[0008] Technical Field
[0009]
[0010] The present invention relates in general to assemblies of wear members engaged in the ground including connectors for securing excavation wear members in place for their use. More specifically, the present invention relates to fasteners that can use a bypass element to resist passage between the locked and unlocked positions to selectively secure the wear members to other wear members.
[0011] Background
[0012]
[0013] Equipment for the displacement of material, such as excavation buckets found in construction, mining and other earthmoving equipment, usually includes replaceable wear parts such as a tooth geared to the ground. They are usually removably mounted to other base structures, such as excavation buckets and come into abrasive, wear contact with the earth and other materials that are moving. For example, excavating tooth mounts provided in the excavation equipment, such as excavation buckets and the like, normally they comprise a relatively massive adapter part which is suitably anchored to the leading edge of the bucket. The adapter part normally includes a nose projecting forward. A replaceable tooth tip usually includes a rearward facing pocket that removably receives the adapter nose. To retain the tooth tip on the adapter nose, transverse openings generally aligned both on the tip of the tooth and on the nose of the adapter can be formed and a suitable connector structure, such as a pin, is urged and retained in shape. forced into the aligned openings to releasably anchor the replaceable tooth tip over its associated adapter nose.
[0014]
[0015] During normal operations, the tooth undergoes charging in several directions. If the tooth is not positioned over the nose in a stable manner, the loads experienced by the tooth can cause additional wear on the adapter. Accordingly, there is an improved wear member assembly that is selectively mounted on the sear members one on top of the other or on the edge of the bucket.
[0016]

[0089] Detailed description
[0090]
[0091] For the purposes of promoting an understanding of the principles of the present invention, reference will now be made to the implementations illustrated in the drawings and specific language will be used to describe them. In any case, it will be understood that no limitation of the scope of the invention is desired. All alterations and other modifications of the described devices, systems and methods and all other applications of the principles of the present invention are fully contemplated as would normally occur to one skilled in the art to which the present invention relates. In addition, the present invention describes in detail some elements or characteristics with respect to one or more implementations or Figures, when those same elements or characteristics appear in later Figures, without said level of detail. It is completely contemplated that the features, components and / or steps described with respect to one or more implementations or Figures may be combined with the features, components and / or steps described with respect to other implementations or Figures of the present invention. For more simplicity, in some cases the same or similar reference numbers are used in all drawings to refer to the same or similar parts.
[0092]
[0093] The present invention relates to an assembly of wear member geared to the ground that includes a support structure, such as a wear member adapter, which can be secured to a bucket edge and another wear member such as a tooth . The assembly also includes a fastener to hold the tooth on the adapter. The fastener, such as a pin, rotates between an unlocked position in which the pin can be removed from its position within the tooth and a locked position in which the pin is prevented from withdrawing from its position within the tooth. The present invention describes a pin configuration that provides strength when the pin is rotated between the locked and unlocked positions. This resistance provides tactile feedback to the operator.
[0094]
[0095] Figure 1 is an exploded perspective view of a wear member assembly 100. According to the present example, the wear member assembly 100 includes a support structure 102, a wear member 104 such as an excavating tooth and a fastener 106. In this implementation, the support structure 102 is representatively a base adapter having a tapered front nose portion 108 with a leading end 119. Alternatively, the support structure may be an intermediate adapter or other type of support structure. A connector opening 110 that is dimensioned to receive the fastener 106 extends horizontally through the nose portion 108 between its opposite vertical sides.
[0096]
[0097] The wear member 104 is a replaceable digging tooth, but it can also be an intermediate adapter or other type of replaceable wear member. A tapered receptacle surface 112 extends forwardly through a rear end 114 of the wear member 104 and, as better illustrated in Figure 6, is configured to complementarily receive the nose portion 108 when the wear member 104 it is telescoped on the nose part 108. With the wear member 104 operatively disposed on the nose portion 108, the pin opening connector 116 (only one of which is seen in Figure 1) extending through the opposite outer walls 118 of the wear member 104 on the receptacle surface 112 align with the nose connector opening 110. As shown in FIG. also described below, the wear member 104 includes interior side cavities such as a locking flange and / or other features that interconnect with the fastener 106 and cooperate to secure the fastener 106 in place and thereby secure the fastener member. wear 104 to the support structure 102.
[0098]
[0099] Referring now to Figures 2-4, the fastener 106 comprises a main body 126 and a locking detent 128. The main body 126 is formed as a cylindrical elongated solid metal connector pin having a fixed axial length extending along the central longitudinal axis 130. In this implementation example, the main body 126 is formed of a single monolithic material. However, in other implementations, different parts of the main body 126 may be formed of opposed materials coupled or otherwise connected together. In some implementations, different parts of the main body 126 can be welded together to form a monolithic structure with no moving parts. The main body 126 includes a longitudinally extending body part 132, a radially extending locking flap 134 and a tool engagement feature 136.
[0100]
[0101] The body part 132 has a substantially circular cross section along its length and includes a distal end 142 and a proximal end 144. In this implementation, the distal end 142 is substantially cylindrical and has a circumferential circumference that substantially has the same radio. The body portion 132 includes a cylindrical portion 146 that extends between the distal end 142 and the proximal end 144. In this example, the cylindrical portion 146 extends along the side having the locking flap 134. In addition, the part of the body 132 includes a slightly tapered portion 148 extending between the distal end 142 and the proximal end 144. The slightly insulated portion 148 may be disposed on the opposite side of the cylindrical portion 146. In some examples, the tapered part 148 is on the opposite side of the locking flap 134. In some examples, the tapered portion 148 may not be directly opposite the locking flap 134.
[0102]
[0103] Each of the cylindrical part 146 and the tapered part 148 have particular purposes. One of the purposes of the cylindrical part 146 is to provide an equal distribution of the loads to the support structure 102 when the fastener 106 is disposed in the connector opening 110 (FIG. 1) of the support structure 102. This can be observed in the cross-sectional view of Figure 5, which shows a cross-sectional view of the assembled wear member 100. Figure 5 shows the cylindrical part 146 of the fastener 106 that faces and is in abutting contact with an interior wall 160 of the connector opening 110 of the support structure 102. Because the cylindrical portion 146 interconnects and meshes with the inner wall 160 (and is arranged to face the leading end 119 of the support structure), it has a shape to equalize the cylindrical part 146 of the fastener 106, the applied loads are evenly distributed along the loading interface 162 corresponding to the interface of the cylindrical part 146 and inner wall 160. This can extend the useful life of support structure 102 by reducing a chance of deformation that can occur over time with uniformly distributed loads. In addition, the tapered part 148 also has a purpose. Still referring to Figure 5, the tapered portion 148 is shown with increasing spacing from a rear portion 164 of the inner wall 160. In this implementation, the separation is present due to the tapered portion 148, which, in this implementation, extends from the distal end 142 towards the proximal end 144 of the body portion 132. The tapered portion 148 forms a side of the body portion 132 conically shaped. As can be understood from the foregoing description, the cylindrical portion 146 forms the opposite side of the body portion 132. The tapered portion 148 provides additional space toward the distal end 142 for a relatively easier insertion and removal of the fastener 106. from the connector opening 110. During use, debris such as dirt or mud can enter any opening or slot between the components, such as between the fastener 106 and the inner wall 160 of the connector opening 110. These debris can making the removal of the fastener 106 from the connector opening 110 more challenging. The tapered part 148 reduces the friction when the fastener 106 is removed from the connector opening 110. In some implementations, the tapered portion 148 is formed at an angle relative to the longitudinal axis 130 in a range of 1-5 degrees. Other angles are also contemplated, both major and minor. Some fastener implementations are cylindrical along the full length of body part 132. Other implementations are conical along the full length of body part 132. Other implementations are also contemplated.
[0104]
[0105] The distal end 142 of the body part 132 may include an end surface 170 formed at an oblique angle 171 relative to the longitudinal axis 130. In some implementations, the end surface 170 is at the angle 171 selected to be within a range of 20 to 70 degrees relative to the longitudinal axis 130. Some implementations have a range of angles of 35 to 55 degrees. Some end surfaces are at a 45 degree angle. As also described below, this angled end surface can cooperate with the wear member 104 to form a push-out release mechanism that helps remove the fastener 106 from the support structure 102 and the member. of wear 104.
[0106]
[0107] The radially extending locking flap 134 is disposed, in the shown embodiment, towards the proximal end 144 of the main body 126. The locking flap 134 extends radially from the body part 132. In some implementations, the locking flap 134 extends substantially from one side of the main body 126.
[0108]
[0109] In the implementation shown, the locking flap 134 has a relatively greater transverse width W (Figure 2) and a relatively smaller axial length L (Figure 1). Other implementations have a locking flap 134 of a different size. Some blocking alters have substantially a fan shape. Other blocking fins have other shapes. The locking flap 134 has a surface facing the distal end 172, a surface facing the proximal end 174, a leading edge 176 and a trailing edge 178. In some implementations, at least one of the facing surface toward the distal end 172 and the surface facing the proximal end 174 are extends along a plane substantially perpendicular to the longitudinal axis 130. In other implementations, at least one of the surface facing the distal end 172 and the surface facing the proximal end 174 extends at an oblique angle in relation to In a plane substantially perpendicular to the longitudinal axis 130. In such implementations, one or both of the surface facing the distal end and toward the proximal end 172, 174 of the locking flap 134 may form a coil about a portion of the shaft. longitudinal 130. In some embodiments, the surface facing the distal axis 172 is substantially formed within a single plane perpendicular to the longitudinal axis 130 and the surface facing the proximal end 174 includes a tapered portion 177 that forms an angled plane oblique or a flat surface adjacent the leading edge 176 and a flat part 179 parallel to the surface facing the distal end 172 adjacent the trailing edge 178. In some implementations, a third flat portion 181 forms a taper extending from the flat portion 179 toward the trailing edge. The flat portion 181 may be configured to dislodge and remove debris when the fastener 106 is rotated to remove it from the wear member 104 and the support structure 102.
[0110]
[0111] The leading edge 176 and the trailing edge 178 can extend substantially in the same direction from the body part 132. For example, they can be relatively parallel to one another. In some examples, less than 10 ° may be diverted from each other. Accordingly, the locking flap may have a relatively rectangular shape. In some implementations, the leading edge 176 and the trailing edge 178 are angled one relative to the other and can form an angle within a range of 0 to 60 degrees. Accordingly, the locking flap can be in the form of a fan. Other angles and shapes are also contemplated. In some implementations, the maximum distance between the leading edge 176 and the trailing edge 178 may be equal to or less than the diameter of the body part 132. In some implementations, the maximum distance between the leading edge 176 and the trailing edge 178 may be greater than the radius of the body part 132, but smaller than the diameter of the body part 132. In some implementations, the maximum distance between the leading edge 176 and the trailing edge 178 may be greater than the diameter of the body. body part. In some embodiments, the axial length L or the thickness of the fin of Lock 134 at the leading edge 176 is smaller than the axial length L or the thickness of the locking flap 134 at the trailing edge 178. In some implementations, the locking flap may have a radial height greater than the radius of the part of the block. body. In some implementations, the axial length L or the thickness of the locking flap 134 at the leading edge 176 is greater than the axial length L or the thickness of the locking flap 134 at the trailing edge 178. In some examples, both the The surface facing the distal end 172 as the surface facing the proximal end 174 of the locking flap may be substantially parallel to one another. In other words, there may not be a taper of the surface facing the distal end 172.
[0112]
[0113] The gear engagement to the tool 136 is disposed at the distal end 142 of the body part 132 and is configured for and arranged to interface with a tool that a user can employ to move the fastener 106 from an unlocked condition to a condition blocked up. In the implementation example shown herein, the gear-to-tool feature 136 is formed as a hexagonal head projecting from one end of the body part 132. Other implementations of the gear-to-tool feature may include a cavity or depression formed at one end of body part 132. The protrusion or cavity may have a hexagonal shape as shown, alternatively may have a square shape, a star, or other shape that may allow engagement with the tool.
[0114]
[0115] In this implementation, the body portion 132 includes a groove 180 dimensioned and arranged to receive the locking detent 128. The groove 180 may be disposed at the proximal end 144 between the locking flap 134 and the gear engaging feature 136 Here, the groove 180 is formed radially within a plane substantially perpendicular to the longitudinal axis 130. In some implementations, the groove 180 extends around only a part of the circumference of the body part 132. In other implementations, the groove 180 extends completely around the circumference of the body part 132. Here, as can be seen in Figure 4, the groove 180 extends only around the a part of the circumference of the body part 132 to minimize any chance of the locking catch 128 inadvertently slipping around the circumference of the body part 132. Other spring designs, including elastomeric or polymeric systems, are also contemplated. .
[0116]
[0117] The locking catch 1728 can be transported and supported by the body part 132. The locking catch 128 can project radially outwardly from the body part 132 and can help maintain the fastener 106 in a locked condition and / or not blocked as a user wishes. In the implementation shown, the lock detent 128 comprises a C-shaped resilient ring that fits inside the groove 180 and the body portion 132. Here, the C-shaped lock retainer 128 includes a protruding part 182 formed of a flexible protrusion and a portion of the spring 184 formed of a C-shaped elastic ring. In this implementation, the legs fit within the groove 180 in such a way that they are flush with or below an outer surface of the part of the body. body 132. The protruding part 182 projects radially outwardly beyond the outer surface of the body portion 132. When the fastener 106 is rotated between an unlocked condition and a locked condition, the projecting portion 182 can be compressed into radial or elastic shape. When the fastener 106 reaches the unlocked condition and / or the locked condition, the projecting portion 182 may be allowed to bounce radially back towards its original condition. This may provide a user with a tactile sensation indicating that the fastener 106 is completely within the locked condition or the unlocked condition, while at the same time, it may contribute to preventing the inadvertent rotation of the fastener from the locked condition to the non-blocked condition. blocked up. This will become more evident in the following discussion.
[0118]
[0119] While the disclosed embodiment employs an elastic ring style locking retainer, other locking retainers are also contemplated. For example, some detents have a different shape from the C shape. Some extend completely around the body part 132. Other implementations employ an elastomeric projection extending from the exterior surface of the body portion 132. When moving between an unblocked condition and a blocked condition, the elastomeric projection can be compressed and then expanded when it is correctly located in the blocked or unblocked condition. The elastomeric locking catch would reduce the possibility of inadvertent rotation during use from the locked condition to the unlocked condition. Other locking catches include spring-loaded seals. Others are also contemplated.
[0120]
[0121] Figure 6 shows in more detail the wear member 104 including the tapered receptacle surface 112 extending through the rear end 114. With reference to both Figure 5 and Figure 6, the wear member 104 includes the openings of connector pin 116 on both opposite sides of the wear member. In the implementation shown, both connector pin openings 116 extend from an outer surface of the outer walls 118 towards the receptacle surface 112. In some other implementations, only one connector pin opening 116 extends from the outer surface toward the receptacle surface 112. In such an implementation, the opposite connector pin opening 116 can be formed only on the inner surface of the receptacle area 112. As shown in Figure 5, the connector pin openings 116 are aligned with each other. Such that the fastener 106 can extend and mesh with the connector pin openings 116 on both opposite sides of the wear member 104.
[0122]
[0123] In this implementation, the connector pin openings 116 include a release opening 202 and a locking opening 204. The release opening 202 is formed as a counter drilling passage extending from the interior wall 203 of the wear member 104. towards the outer wall 118. Accordingly, the detachment opening 202 includes a larger diameter portion 206 and a smaller diameter portion 208. The larger diameter portion 206 is sized to receive the distal end 142 of the fastener 106. A bottom surface 210 of the part with a larger diameter 206 is oblique in relation to an axis through the part with a larger diameter 206 which may also be parallel to the longitudinal axis 130 of the fastener 106 when the fastener 106 is arranged in the pin openings 116. In the shown, the bottom surface 210 is angled to be substantially parallel to the end surface 170 of the fastener 106 when the fastener is in a locked condition, in a manner shown in Figure 5. The purpose of the oblique surface to cooperate with the end surface 170 (of the push-out feature) to eject the fastener during rotation is further explained below. The oblique surface is also oblique to a transverse axis passing through both connector pin openings 116. This transverse axis may be coaxial with the shaft 130 shown in Figure 5.
[0124]
[0125] The part with a smaller diameter 208 extends from the bottom surface 210 to the outer wall 118 of the wear member 104. The passage formed by the part with a smaller diameter 208 can provide access to the fastener 106 by a user. This may be useful if for example the clip 106 were housed within the connector opening 110 of the support structure 102 or the connector pin openings 116 of the wear member 104. The passage may allow a user to push the clip to through the connector opening 110. For example, a user can insert an axis through the passage for contact with the distal end of the clip 106 and can touch the end of the shaft to release the clip 106 from the connector opening 110 and / or the connector pin openings 116. Some implementations also include a tool receiver that allows a user to leverage the fastener from the connector pin opening 116 if necessary. For example, the protrusion, flap, or other features on the body part can be used to leverage the fastener 106 from the piercing.
[0126]
[0127] The locking opening 204 has a shape for axially receiving the fastener 106 therethrough and allowing the fastener 106 to be rotated from an unlocked condition to a locked condition. As used herein, the non-locked condition is a position that allows the fastener 106 to be removed from the locking opening 204. The locked condition is a position in which the locking flap 134 is disposed behind the wall that separates the receptacle surface 112 from the external side wall 118. The locking aperture 204 accordingly includes a shape that has a greater size that the axial profile of the fastener 106. The blocking opening 204 is shown in detail in Figures 7 and 8. Figure 7 shows a perspective view of the external part of the locking opening 204, while Figure 8 shows a internal part of the locking opening 204. As seen in Figure 7, the locking opening 204 has a central opening part 209 having a generally bulbous shape, a first region receiving the retainer 211, a second receiving region the retainer 212 and a region receiving the locking flap 214. The first and second regions receiving the retainer 211, 212 extend radially outwardly from the central opening portion 209. A retainer compression region 216 formed in the outer wall 118 of the wear member 104 separates the first and second regions receiving the retainer 211,212. As best seen in Figure 8, the receptacle side of the wear member 104 includes a wear member lock portion 219 having a rear side that forms a locking flange surface 220. In the implementation shown, the surface of locking tab 220. In the implementation shown, the locking tab surface 220 is recessed below the inner wall 203 of the receptacle surface 112. The locking tab surface 220 extends towards a hard mechanical stop 222. When the fastener 106 is positioned in the locking opening 204, it can be rotated in such a manner that the locking flap 134 is behind the wear member locking part 219 adjacent the locking flange surface 220. The hard mechanical stop 222 can prevent over-rotation of the fastener 106 and consequently can ensure that the cylindrical portion of the fastener is correctly aligned with the interface with the int charge erfaz 162 of connector opening 110 (Figure 5).
[0128]
[0129] Figures 9 A, 9B and 9C illustrate a process for rotating the fastener 106 from an unlocked condition to a locked condition according to an implementation example. These Figures show an end view of the fastener 106 and a side view of the wear member 104. Figure 9A illustrates the fastener 106 in an unlocked condition; Figure 9B illustrates the fastener 106 in an intermediate position between the unlocked condition and the locked condition; and Figure 9C illustrates the fastener 106 in a locked condition.
[0130] Figure 9A shows the clamp 106 aligned for insertion through the locking opening 204. In this position, the locking tab 134 is aligned with the region receiving the locking flap 214 and the locking catch 128 is aligned with the first region receiving the retainer 211. In this alignment, the clip 106 extends through the locking opening 204 of the wear member 104, through the connector opening 110 in the support structure 102 and in the opening of detachment 202 in the wear member 104. At the same time, the distal end of the fastener may abut the flat, oblique bottom surface 210 of the release aperture 202 (Figures 5 and 7). With the fastener 106 disposed in this non-locked condition, a user can engage the engaging feature with the tool 136 with a rotating tool, such as a key or plug system, for example, to rotate the fastener 106 from the condition not blocked
[0131]
[0132] Figure 9B shows the fastener 106 in the process of being rotated from the unlocked condition to the locked condition. As shown in Figure 9B, the leading edge 176 of the locking flap 134 begins to slide behind the wear member lock part 219. At the same time, the lock detent 128 moves outward from the first region. which receives the retainer 211 and engages the structure forming the compression region of the retainer 216. As such, a user can tactually feel another resistance to rotation when the locking detent 128 compresses radially while passing through the compression region of the detent 216. The implementation having a locking flap with a surface facing the tapered proximal end 174 can slide against the locking flap surface 220 (Figure 8) which forms a part of the wear member locking part. 219. Since the locking flange surface 220 is at an oblique angle, when the locking flap 134 travels along the locking flange surface 220, the fastener 106 moves axially further inward toward the release opening 202. The oblique nature of the flat bottom surface 210 of the larger diameter portion 216 allows the fastener 106 to advance further towards the release aperture 202. A user continues to rotate the fastener 106 towards the blocked condition.
[0133] Figure 9C shows the fastener 106 in the locked condition. In this condition, the fastener is rotated until the locking flap 134 is completely behind the wear member locking part 214. Here, the facing surface toward the proximal end 174 of the locking flap 134 may be engaged or in position for interconnection with the locking tab surface 220. Also in this condition, the leading edge 176 of the locking tab 134 can be engaged against the hard mechanical stop 222. In this position, the cylindrical portion of the fastener 106 can align with the loading interface 162 of the support structure 102 (Figure 5). At the same time, in this position, the end surface 170 of the fastener 106 can be substantially aligned with the oblique flat bottom surface 210 of the larger diameter part 206 of the release aperture 202. As can be seen in the Figure 9C, the locking detent 128 has moved out of the retainer compression region 216 and into the second region receiving the retainer 212. As the locking detent 128 is compressed, a user can feel the detachment of the retainer in a tactile manner. of lock 128 while moving to the second region receiving the retainer 212. This may signal to the user that the fastener has reached the locked condition. In addition, the locking catch 128 can prevent inadvertent rotation of the fastener 106 back toward the unlocked condition. For example, the relatively higher force required to rotate the locking detent 128 out of the second region receiving the retainer 212 and over the region that compresses the retainer 216 may prevent the fastener from unintentionally or unintentionally rotating when digging, digging, pushing or otherwise use the wear member with its intended purposes.
[0134]
[0135] It is important that the wear member assembly 100 is provided with a release assist mechanism in the shape of the tapered end of the fastener and the oblique bottom surface 210 of the larger diameter portion 206 of the release aperture 202. When a user desires to remove the fastener 106, the fastener 106 of the locked condition shown in Figure 9C can rotate toward the non-blocked condition shown in Figure 9A. When this occurs, the oblique end of the fastener 106 abuts the oblique bottom surface 210 of the larger diameter portion 206 of the release aperture 202. These oblique surfaces push the fastener for displacing it axially towards the blocked opening 204. When the fastener 106 moves towards the blocked opening 204 and can finally project at least partially out of the locking opening 204, the fastener 106 can be more easily grasped and removed from the wear member 104. Accordingly, rotation in the counter-clockwise direction may not only unlock the fastener 106, but may also partially eject the fastener 106.
[0136]
[0137] With the wear member mounted on another structure, such as a bucket, debris such as dirt, mud, clay, etc., can fill the open portions of the locking opening 204. When the fastener is to be removed from the wear member 104 , the trailing edge 178 becomes the leading edge intended to remove or break the hardened earth material in the blocked opening 204. To achieve this, the trailing edge 178 can be formed with a flat surface substantially parallel to the longitudinal axis 130.
[0138]
[0139] In some implementations, the support structure 102 and the fastener 106 are configured such that the fastener 106 does not fully extend through the support structure 102. In these implementations, the support structure 102 may include the bottom surface oblique 210 shown in the peel opening 202. That is, the support structure may include a perforation on each side aligned with the pin openings 116 of the wear member being on the support structure.
[0140]
[0141] The design of the wear member assembly described herein may provide other advantages that can not be obtained by the prior art systems. The simplicity, reliability and form achieved by the fastener, the holes in the wear member and the character of the support structure can provide reliability as well as an efficient, non-hammered mounting of a wear member and removal from a structure. of support.
[0142]
[0143] Figures 10-19C show an implementation of a wear member assembly. Figure 10 is a view of a wear member assembly geared to the ground according to examples of implementations of the present invention. In the implementation shown, the wear member assembly 1000 includes a tooth (or wear member) 1004, a support structure such as an adapter 1002 and a fastener 1006.
[0144]
[0145] Adapter 1002 includes a longitudinally projecting nose that extends into a posterior cavity of tooth 1004 (not shown in Figure 10). The nose may include a transverse hole (not shown in Figure 10) formed therein to receive the fastener 1006. In this implementation example, the tooth 1004 also includes a hole through which the fastener 1006 may be inserted.
[0146]
[0147] Figure 11 illustrates an exploded view of the fastener 1006. Figure 12 illustrates a mounted view of the fastener 1006. Figure 18A illustrates a cross-sectional mounted view of the fastener 1006 disposed within other components of the wear assembly 1000. With reference to these figures and according to the present example, the fastener 1006 includes a rigid body 1201 and a lid 1212. The fastener 1006 also includes a rotation resistant element 1210. The lid 1212 is arranged to be connected to the main body 1201 of such that the rotation resistant element 1210 is maintained between the lid 1212 and the main body 1201.
[0148]
[0149] In the present example, the main body 1201 includes an axis 1204 and a head 1206. An end 1203 of the shaft 1204 includes a feature for pushing 1202, or a release mechanism and the other end of the shaft 1204 is supported and extended from the head 1206. In the present example, head 1206 and shaft 1204 form a single monolithic component. In some examples, head 1206 can be a separate component that can be connected to shaft 1204 to form a single rigid unit. The shaft 1204 includes an elongated cylindrical part having a substantially circular cross section. In some examples, shaft 1204 may taper toward end 1203 to allow easier insertion into the transverse hole in the nose portion and tooth orifice 1104.
[0150] The push out feature 1202 operates in concert with the tooth 1104 or the adapter 1102 such that when the shaft 1204 is rotated, the hole in which it is inserted is pushed out. In the implementation shown, the push-out feature 1202 may be a tapered end. In some implementations, the tapered end is a flat surface at an oblique angle relative to the longitudinal axis of the shaft 1204. The tapered end may be engaged against an angled edge within the tooth 1104 or the adapter 1002 as described above. The rotation of the shaft 1204 can cause the tapered end of the push out feature 1202 to slide against a corresponding tapered surface on the tooth 1004 or the adapter 1002, pushing the shaft 1204 (and similarly the fastener 1006) to move it. axially such that the fastener 1006 can be more easily grasped and removed from the wear member assembly 1000. In the implementation shown, the longitudinal axis 1213 of the shaft 1204 is also on the same line with the axis of the fastener 1006.
[0151]
[0152] The other end 1205 of the main body 1201 includes the head 1206. In this implementation, the head 1206 has a cross-sectional diameter greater than the axis 1204. The head 1206 includes a gear cavity 1222 that opens along the direction axially at the proximal end of the shaft 1204. As will be explained in more detail below, the gear cavity has a size and shape to receive a gear protrusion 1220 of the cap 1212. In the example of implementation shown, the head 1206 1206 it also includes two pin holes 1207 having a size and shape for receiving a holding pin 1226. In the implementation shown, the pin holes 1207 are disposed on opposite sides of the gear cavity 1222 in such a manner that the pin Support 1226 can be positioned in both pin holes 1207 at the same time. After the cap 1212 is inserted into the gear cavity 1222, the holding pin 1226 can be inserted into the pin holes 1207 to hold the cap 1212 in place in relation to the main body 1201. Although the implementation shown includes a single support pin 1226, other implementations use several support pins. Still others use mechanical-mount fasteners that are not support pins. For example, some implementations use adhesives, epoxies, solder, threads, other gear characteristics to secure the lid 1212 to the main body 1201.
[0153]
[0154] In this implementation example, the head 1206 also includes a radially extending locking flap 1224. The locking flap 1224 helps secure the fastener 1006 instead of securing the tooth 1004 in the adapter 1002. For example, when the fastener 1006 is rotated to the locked position, the locking flap 1224 rests behind a surface of the tooth 1004 or the adapter 1002 in a manner that prevents removal of the fastener 1006 from the tooth 1004 or the adapter 1002. Similarly, when the fastener 1006 is in an unlocked position, the locking flap 1224 is positioned such that it fits through a cavity or opening within the tooth 1004 or the adapter 1002, thereby allowing removal of the fastener 1006. If either the locking flap 1224 is disclosed projecting from the head 1206 of the main body 1201, in other implementations, the locking flap is disposed over the lid 1212 or from the e 1204. In some implementations, locking flap 1224 includes axially offset surfaces 1225a, 1225b that lie within parallel planes. In some implementations, one or both surfaces 1225a, 1225b are angled to lie within planes that are oblique to longitudinal axis 1213. In some embodiments, these surfaces may be similar to the surfaces facing the distal end and the facing surface. towards the proximal end 174 described with reference to Figures 2-8 and 9A-9C. The locking flap 1224 can be inclined or have a size similar to the locking flap 134 described herein.
[0155]
[0156] The cap 1212 includes a gear protrusion 1220, a contact portion 1218 and a head 1219. The gear protrusion 120 projecting axially from the contact portion 1218 and has a size and shape to fit within the gear cavity 1222 , as shown in Figures 11 and 18A. In the present example, the gear protrusion 1220 has a cross section with a substantially square shape. Therefore, the gear cavity 1222 also has a substantially square shape. Accordingly, in the implementation shown, the gear cavity 1222 and the gear protrusion 1220 have substantially the same cutting shape cross. Although it is shown with a substantially square shape, other profiles or shapes can be used. In some implementations, the cross-sectional shape of the gear cavity 1222 and the gear protrusion 1220 are formed as rectangular, triangular or other polygonal shapes. Other forms of cross section are also contemplated. Due to the equal shapes or surfaces, the lid 1212 and the main body 1201 can be rotationally fixed to one another. Some implementations are not based on equal shapes or surfaces, but instead rely on the support pin 1226 or other support structure to rotationally fix the cover 1212 and the main body 1201. As can be seen, the gear protrusion 1220 of this implementation also includes a through hole 1217. When the gear protrusion 1220 is fully inserted into the gear cavity 1222, the through hole 1217 is aligned with the pin holes 1207 so that the holding pin 1226 can be inserted all the way through them so as to hold the lid 1212 on the main body 1201. Other mechanisms are also contemplated to secure the lid 1212 to the main body 1201 in such a way that the rotation of the lid 1212 causes the corresponding rotation of the main body 1201.
[0157]
[0158] In the present example, the contact portion 1218 is a non-circular circumferential profile that forms an outer surface of a portion of the lid 1212 and is positioned adjacent the gear boss 1220. The contact portion 1218 has a size and a which form must be received by the rotation resistant element 1210. In this implementation, the contact portion 1218 includes a plurality of substantially planar surfaces that face radially outwardly. These flat surfaces are separated by edges or corners 1229 and are designed to lie flat against the inner surfaces of the rotation resistant element 1210 when the fastener is in the locked or unlocked position. Although described as flat surfaces, the surfaces may have concave or convex portions separated by edges or corners 1229.
[0159]
[0160] The head 1219 of the lid 1212 may have a diameter that is similar or substantially the same as that of the head 1206 of the main body 1201.
[0161] The head 1219 limits or prevents axial translation of the rotation-resistant element 1210 while the lid 1212 is connected to the body 1201. Namely, the body 1219 secures the rotation-resistant element 1210 in place axially, although the head 1219 and the complete cover 1212 can be selectively rotated in relation to the rotation resistant element 1210. The head 1219 also includes a tool connection feature shown as a hole 1216 that can be used to rotate the fastener 1106. In the present example, the hole 1216 has a hexagonal shape and is aligned with the longitudinal axis. Therefore, a tool with a hexagonal shape can be inserted into the hole 1216 and used to rotate the fastener 1106 relative to the rest of the wear assembly 1100. In some examples, a plug 1214 can be inserted into the hole 1216 during the normal operation of the wear member to prevent the accumulation of debris, such as dirt, within the orifice 1216. The plug 1214 may be a rubber or polymer plug that can be removed to provide access to the orifice 1216. In some examples, it may be be a cut 1215 on one of the hexagonal sides of the hole 1216 that allows a tool, such as a screwdriver, to slide inside and remove the plug 1214. In addition, the cut 1215 can provide a hold for the tool to remove dirt and orifice debris 1216 in case the plug 1214 is not used.
[0162]
[0163] The rotation resistant element 1210, sometimes referred to as the locking clip or spring clip, is designed to resist unwanted or unintended rotation of the lid 1212 and the main body 1201 and allow desired or intentional rotational movement of the lid 1212 and the main body 1201. The rotation resistant element 1210 may be similar to the spring portion 184 described above. According to the present example, the rotation resistant element 1210 includes an inner contact feature 1211 and an interference feature 1209. The inner contact feature 1211 includes a plurality of inwardly facing flat surfaces that are configured to engage to the surfaces facing away from the contact portion 1218 of the lid 1212 in such a manner that the flat surfaces of the contact portion 1218 fit rotatably against the flat surfaces of the inner contact feature 1211. The element Resistant to rotation 1210 can be formed from an elastic material that it has elastic characteristics in such a way as to allow the desired or intentional rotation of the lid 1212 and the main body but that the unwanted or unintentional rotation is resisted. Specifically, the rotation of the cap 1212 and the main body 1201 in relation to the rotation-resistant element 1210 between a locked position and an unlocked position will produce the expansion, such as the radial expansion, of the rotation-resistant element 1210. The rotation of the lid 1212 in relation to the rotation-resistant element 1210 pushes the rotation-resistant element 1210 outwards. The compliant and elastic nature of the rotation resistant element 1210 provides resistance to this outward movement and therefore provides resistance to rotation of the fastener 1006 between the locked and unlocked positions. This provides a tactile feedback to the user when the clip rotates between an unlocked position and a nocked position. As such, when a user rotates the lid 1212 and the main body 1201 in relation to the rotation-resistant element 1210, the resistance to rotation increases for a first part of the rotation and is then reduced for a second part of the rotation , providing tactile feedback to the user. Because the resistance to rotation increases during rotation, the tendency of inadvertent rotation can be minimized or prevented.
[0164]
[0165] In the present example, the interference feature 1209 is formed as a single protrusion that is designed to fit within a cavity or slot (not shown) of the tooth 1004 or the adapter 1002. The cavity provides mechanical interference that prevents rotation of the tooth. the interference feature 1209 of the rotation resistant element 1210 in relation to the tooth 1004 or the adapter 1002. Accordingly, when the fastener 1006 is rotated in relation to the tooth 1004 or the adapter 1002, the rotation resistant element 1210 it is not.
[0166]
[0167] Figure 12 illustrates a perspective view of the fastener 1006 with a rotation-resistant member 1210. The cap 1212 is secured to the head 2006 of the shaft 1204. In addition, the rotation-resistant member 1210 fits over the contact portion 1218 and secured in place by the lid 1212 and prevented from being removed without removing the lid 1212.
[0168] In some examples, the rotation resistant element 1210 can be formed with a single monolithic component as shown or described in Figures 11-15. In some examples, however, the rotation resistant element 1210 may include more than one component as shown and is described with reference to Figures 21-24C. For example, the rotation resistant element 1210 may include a bypass member and a separate ring piece (not shown) that fits with the bypass member. In said example, the bypass member may form some of the surfaces of the inner contact feature 1211 while the ring piece may form some of the other inner surfaces of the inner contact feature 1211, or alternatively the bypass member may forming all surfaces of the inner contact feature 1211.
[0169]
[0170] In some implementations, the rotation resistant element 1210 includes a position indicator 1221. The position indicator 1221 is a fixed feature that can be used for reference to identify the relative rotational position of the lid 1212. In the implementation shown , the position indicator 1221 is a depression formed in a surface of the rotation resistant element 1210. A paint or marker of a bright color can be applied in such a way that the indicator of position 1221 is easy to identify for an operator . As can be seen in Figure 12, the lid 1212 can also include indicators 1223. In the example shown, the indicators of the position 1223 are shown as an open padlock and a closed padlock. In some implementations, the indicators of position 1223 are simply lines, points, depressions, or other indicator. In some implementations, these can be painted or colored to be easily visible to an operator. Some implementations do not include position indicators.
[0171]
[0172] Figure 13 illustrates a deflection member 1300 which forms all or part of the examples of rotation resistant elements 1210. In the present example, the diverting member 1300 is a C-shaped member. The bypass member 1300 includes two flexible arms 1302a, 1302b and interference feature 1209. Arm 1302a includes an interior facing upper surface 1304a and arm 1302b includes an upward facing bottom surface 1304b.
[0173] in this implementation, the surfaces 1304a, 1304b are substantially planar. When mounted with the lid 1212, the surfaces 1304a, 1304b can be adjusted against the substantially planar surfaces of the contact portion 1218 (Figure 2A). In the present example, the bypass member 1300 includes a single solid protrusion 1306 that forms the interference feature 1209.
[0174]
[0175] In some examples, the deviation member 1300 can be made of an elastic material such as a plastic or polymer. In some examples, the bypass member 1300 can be made of a metallic material having sufficient flexibility. The resilience allows the arms 1302a, 1302b to flex elastically and separate when a rotational force is applied to the cap 1212 and therefore the contact portion 1218. When the cap 1212 and the main body 1201 are in the locked or locked positions. not locked, then the flat surfaces 1304a, 1304b abut or are disposed adjacent the flat surfaces of the contact portion 1218, providing a bypass force against inadvertent rotation between the locked and unlocked position. However, when the contact part is rotating, the spring arms 1302a, 1302b can flex outwardly, allowing the bypass force to be exceeded and allowing rotation between the locked and unlocked positions. Therefore, the arms provide resistance to said rotational movement between the locked and unlocked positions.
[0176]
[0177] Figure 14 shows the fastener 1006 disposed within a bore or hole 1402 on one side of the tooth 1004. The head 1219 of the lid 1212 is visible while the main body 1201 is disposed in the interior and through the hole 1402. As shown in FIG. can note, the interference feature 1209 of the rotation resistant member 1210 fits within a cavity 1406 within the tooth 1004. In addition, the locking flap 1224 fits within a locking flap that receives the opening or extension 1404 of hole 1402. Figure 14 shows fastener 1006 in the unlocked position with lock adjustment 1224 aligned within extension 1404. With lock flap 1224 aligned as shown, fastener 1106 can be moved axially and removed from the hole 1402 on the side of the tooth 1004. The locked and unlocked positions are also described below.
[0178] Figure 15 illustrates another example of the bypass member for use with or as the rotation resistant element, having the reference number 1500. In a similar manner to the bypass member 1300 discussed herein, the bypass member 1500 includes two arms 1502a, 1502b each of which has an interior surface 1504a, 1504b that is designed for the contact portion of the contact portion 1218 of the cover 1212. The bypass member 1500 also defines an interference feature 1506 that includes two protuberances 1508a, 1508b. the protuberances 1508a, 1508b provide interference with the adapter 1002 or the tooth 1004 in a manner that resists rotation of the bypass member, even when the cover 1212 rotates.
[0179]
[0180] Figure 16 shows the fastener 1006 disposed within the bore or hole 1402 on one side of the tooth 1004. As can be seen, the protuberances 1508a, 1508b of the rotation resistant element fit within a cavity 1406 within the tooth 1004 The locking flap 1224 fits within the opening or extension of the locking flap 1404. The fastener 1006 is shown in the unlocked position and the description of Figure 14 is also applicable here.
[0181]
[0182] Figures 17A-17C show a cross section of the contact portion 1218 in different positions with respect to the inner contact feature 1211. Each of Figures 17A and 17C illustrates the fastener 1006 in one of the locked and unlocked positions. For purposes of explanation only, Figure 17A is treated as the unlocked position and Figure 17C is referred to as the locked position. Figure 17B shows the rotation halfway between the locked and unlocked positions. With reference to Figure 17A in the unlocked position, the locking flap 1224 is positioned such that it allows the fastener to be removed from the wear member 1004 (not shown). In this position, an outer surface 1701 of the contact portion 1218 bears against an inner surface 1702 of the inner contact feature 1211. An outer surface 1703 of the contact portion 1218 faces the interference feature 1209. An outer surface 1705 of the contact part 1218 is supported against an interior surface 1706 of the characteristic of inner contact 1211. An outer surface 1707 of the contact portion faces away from the interference feature 1209.
[0183]
[0184] Figure 17B illustrates the fastener approximately midway between the unlocked position (shown in Figure 17A) and the locked position (shown in Figure 17C). In this position, the outer surface 1701 has moved away from the inner surface 1702. The outer surface 1703 has moved towards the inner surface 1706. The outer surface 1705 has moved away from the inner surface 1706. The outer surface 1707 is It has moved towards the inner surface 1702. This places an outward force on the bypass member 1300. In some examples, the outward force pushes the two flexible arms 1302a, 1302b of the bypass member 1300 outwards. In some examples, the force towards the outside compresses the material forming the arms 1302a, 1302b while the arms remain substantially stationary. In both cases, rotation between the locked position and the unlocked position is resisted, thereby providing tactile feedback to an operator.
[0185]
[0186] Figure 17C illustrates the fastener in the locked position. Therefore, the locking flap is positioned in such a manner as to prevent removal of the fastener from the wear member 1004 (not shown). After rotation towards the locked position, the outer surface 1701 now faces towards the interference feature 1209. The outer surface 1703 now bears against the inner surface 1706. The outer surface 1705 now looks in the opposite direction to the interference characteristic 1209. The outer surface 1707 now bears against the inner surface 1702.
[0187]
[0188] While Figures 17A-17C illustrate only two discrete positions (blocked and unblocked), it is understood that other implementations may include more discrete positions. For example, in the present example, there are four flat surfaces in both the inner contact feature 1211 and the contact part 1218. Therefore, there may be four discrete positions. In some examples, the contact portion 1218 and the interior feature 1211 may have a different number of flat surfaces and allow a number different from discrete positions. For example, there may be three flat surfaces with a triangular shape, thus allowing three discrete positions. Alternatively, there may be five flat surfaces, thus allowing five discrete positions. In such cases, the rotation resistant element resists rotation between the positions and therefore a tactile feedback is provided to the user who is rotating the fastener 1006. Also, for purposes of illustration, the rotational distance between the locked positions and not blocked is 90 °. However, other implementations may be provided to provide any rotational distance between the locked and unlocked positions according to the configuration of the contact portion 1218 and the interior features 1211.
[0189]
[0190] As illustrated, the rotation resistant element 1210 remains in place while the contact portion 1218 of the lid 1212 rotates. In other words, the interior surfaces 1702, 1706 remain in place while the exterior surfaces 1701, 1703, 1705, 1707 rotate.
[0191]
[0192] Figures 18A and 18B illustrate various cross-sectional views of the fastener 1006 in an unlocked position. Figure 18A illustrates a cross-sectional view along the longitudinal axis 1804 of the fastener 1806. According to the present example, the fastener 1006 is shown inserted into the wear member 1004 and the adapter 1002, thereby preventing removal of the wear member 1004 from the adapter 1002. Specifically, the elongated main body 1201 extends through the adapter 1002 and extends into a cavity 1802 formed within an interior surface 1801 on the far side of the wear member 1004. The cavity 1802 includes an inwardly facing tapered surface form 1803 to cooperate with the push out feature 1202 of the fastener 1006. In this implementation, the locking flap 1224 is shown extended outwardly from the main body 1201, although other implementations have the locking flap 1224 extending outwards from the lid 1212. Although it is not quite clear from the perspective of Figure 18A, the locking flap is in a position to allow removal of the fastener 1006. Figure 18A also illustrates the fastener completely assembled with the lid 1212 secured to the main body 1201 with the rotation resistant element 1210 between them.
[0193]
[0194] Figure 18B illustrates a diagonal cross-section along the locking flap 1224. As illustrated, the locking flap 1224 is positioned so as to align with the extension of the hole 1404, thus allowing the removal of the fastener 1006 In addition, the interference feature 1209 is shown positioned within the cavity 1406.
[0195]
[0196] Figure 18C is a diagram showing a view from the inside of the cavity of the wear member 1004. This view shows the hole 1402 through which the locking pin can be inserted. When the locking pin 1006 is first inserted, the locking flap 1224 fits inside the receptacle 1812. When the locking pin 1006 is rotated from the unlocked position to the locked position, the outer edge of the locking flap 1224 moves along the adjacent surface 1818. Furthermore, the surface facing towards the proximal end 1225 a (shown in Figure 12) of the locking flap 1224 bears against the inclined surface 1816. The inclined surface 1816 by it thus acts as a push-in feature because when the locking flap is rotated, the inclined surface pushes the locking pin 1006 along the axial direction further toward the hole 1402. In some implementations, the inclined surface 1816 is a relatively flat ramp. Accordingly, there is a linear relationship between rotation and axial displacement of locking pin 1006 in the hole. In other implementations, the inclined surface 1816 has a relatively smooth curvature. Accordingly, there is a non-linear relationship between the rotation and an axial displacement of the locking pin 1006 in the hole. In still other embodiments, the inclined surface 1816 has a plurality of surfaces that can form a stepped relationship. For example, Figure 18C shows the surface 1816 that is formed of a plurality of levels or stages. In the example shown, the surface 1816 includes three stages, shown as a flat 1816a, a ramp 1816b and a flat 1816c. When the locking pin 1006 rotates, the locking flap slides on the plane 1816a with the axial displacement of the locking pin 1006. It then slides on the ramp 1816b causing a more axial displacement of the locking pin 1006, thereby pushing towards the interior of the locking pin 1006. It then slides on the plane 1816c to be secured in the locked position. Other provisions are also contemplated.
[0197]
[0198] Figures 19A, 19B, 19C illustrate various cross-sectional views of the fastener 1006 in a locked position. According to the implementation shown herein, the fastener 1006 is consequently rotated 90 ° from the position shown in Figures 18A and 18B. In the locked position, the fastener 1006 is advanced into the holes 1404 in the wear member 1004 and the adapter 1002. As can be seen, the outward push feature 1202 of the shaft 1204 forming part of the main body 1201 is adjusted adjacent to the tapered facing surface 1803 in the wear member 1004. In some implementations, the fastener 1006 may extend only partially in the adapter 1002. In said implementation, the tapered surface 1803 may be formed as a part of the adapter 1002. When the fastener 1006 rotates, the outward-pushing feature 1202 engages the tapered surface 1803 and the new rotation pushes the fastener 1006 to move axially from the position shown in Figure 19B to the position shown in the Figure 18.
[0199]
[0200] Figure 19A is a view along the axis of the fastener 1006 placed within the bore or hole 1402 on one side of the tooth 1004 and in the unlocked position. As can be seen, the interference feature 1209 of the rotation resistant member fits within a cavity 1406 within the tooth 1004. In addition, the locking flap is rotated to be positioned behind an interior surface of the wear member 1004.
[0201]
[0202] Figure 19B illustrates a cross section of the fastener 1006 along the longitudinal axis 1804. While the shaft has been rotated in such a manner that the locking flap 1224 is in a different position, the rotation resistant element 1210 and its characteristic of interference 1209 remain substantially within the same position within the cavity 1406. In other words, the main body 1201 and the cap 1212 have been rotated while the rotation resistant element 1210 remains substantially in place.
[0203] Figure 19C illustrates a diagonal cross section along the locking flap 1224. As illustrated, the locking flap 1224 rests behind an interior surface 1902 (also identified as inclined surface 1816 in Figure 18C) of the member. of wear 1004. Therefore, the fastener 1006 is prevented from being removed.
[0204]
[0205] Figure 20 is a flow chart showing an illustrative method for inserting a fastener having a rotation resistant element 1210 as described herein, according to an example of implementation. In the present example, the 2000 method includes, in 2002, inserting a shaft of a fastener through aligned holes of a first wear member and a second wear member. In some implementations, the insured wear member is an adapter or intermediate adapter such as adapter 1002.
[0206]
[0207] In 2004, the 2000 method also includes engaging the gear feature to the tool by inserting a tool into a hole that receives the tool in the fastener. The tool receiving orifice may have a polygonal shape such as a hexagonal shape. Therefore, the tool can have a part with a similar shape to engage the hole that the tool receives.
[0208]
[0209] The method 2000 further includes, while preventing rotation of the spring clamp relative to the first wear member, rotating the main body and the fastener cap from the unlocked position to the locked position. While this occurs, the edges of the flat surfaces facing inward that fit with the flat surfaces facing radially outwardly of the contact portion flex, compress or move arms of the rotation-resistant element.
[0210]
[0211] Figure 21 is a diagram showing a perspective view of a pin 1006 with a multi-component rotation resistant member 2102 having an inner ring 2106 and an outer ring 2104. The rotation resistant member 2102 works in conjunction with the main body 1201 and the lid 1212 in similar to the rotation resistant element 1210 described above. Specifically, the main body 1201 and the cap 1212 rotate together with respect to the rotation resistant element 2102. The components of the main body 1201 and the cap 1212 illustrated in Figure 21 are similar to those illustrated in Figure 11 and are not repeated here.
[0212]
[0213] The outer ring 2104 of the rotation resistant member 2102 includes an interior facing surface 2112 that has a size and shape to fit against an exterior facing surface 2114 of the inner ring 2106. The outer ring 2104 includes a feature interference 2108 which may include one or more protuberances that are designed to fit within a cavity or slot (not shown) in tooth 1004 or adapter 1002. In the present example, interference feature 2108 includes two protuberances 2110. However, in some examples, there may be a single protrusion such as the protrusion shown in Figure 13. In some examples, the outer ring 2104 may be made of a rigid material such as a metal, a compound or other material. Figure 22 shows a closer view of the outer ring 2104.
[0214]
[0215] The inner ring 2106 has a size and shape to fit within the outer ring 2104. Specifically, the outer facing surface 2114 of the inner ring 2106 is designed to fit against the interior facing surface 2112 of the outer ring 2104. The inner ring 2106 includes an ear portion 2113 with a shape such that the outer surface 2114 is not circular. This prevents the rotational movement of the inner ring 2106 with respect to the outer ring 2106. The inner facing surface 2112 of the outer ring 2104 also includes a corresponding non-circular shape. In some implementations, the inner ring 2106 is secured within the outer ring 2104 using an adhesive such as an epoxy, a solder, or other adhesive. In some examples, the inner ring 2106 may not have an ear portion 2113 and instead may be rotatable within the outer ring 2104. In said example, the outer ring 2104 may have an inner surface with a polygonal shape such that a inner ring with a similar polygonal surface can rotate between discrete positions within outer ring 2104.
[0216] The inner ring 2106 includes a group of inwardly facing surfaces 2116. In the present example, the inner ring 2106 includes four substantially planar, inwardly facing surfaces 2116a, 2116b, 2116c, 2116d, which are shown in more detail in the FIGS. Figures 24A-24C. The inward facing surfaces 2116a, 2116b, 2116c, 2116d have a size and shape to fit against the outward facing surfaces of the contact portion 1218 on the lid 1212. The inner ring 2106 may be made from a elastic material such that it can be compressed by rotation of the contact portion 1218 of the lid 1212. For example, the inner ring 2106 can be made of rubber, polyurethane, high density polyethylene, polyoxymethylene, molten nylon and other materials properly elastic. Figure 23 shows a closer view of the inner ring.
[0217]
[0218] Figures 24A, 24B and 24C are diagrams showing the rotation of the pin with respect to the rotation resistant element of Figure 21. Figure 24A shows the pin in an unlocked position. In said position, four inwardly facing surfaces 2116a, 2216b, 2116c, 2116d of the inner ring 2106 fit against the four outwardly facing flat surfaces 1218a, 1218b, 1218c, 1218d of the contact portion 1218. Specifically, surface 2116a rests against surface 1218a. The surface 2116b rests against the surface 1218b. The surface 2116c rests against the surface 1218c. The surface 2116d rests against the surface 1218d.
[0219]
[0220] Figure 24B shows the locking flap 1224 rotating between the unlocked position and the locked position. When the main body 1201 is rotated, the contact portion 1218 is rotated with respect to the rotation-resistant element 2102. Specifically, as described above, the interference feature 2108 rests within a slot or cavity within the tooth 1004 or of the adapter 1002, which prevents the rotation-resistant element 2102 from rotating with the main body 1201. The rotation of the contact portion 1218 with respect to the inner ring 2106 causes the compression of the parts of the inner ring 2106. Specifically, the parts rounded between the flat surfaces facing outwards 1218a, 1218b, 1218c, 1218d are pressed against the supe rfic ie sp la nasquem iran h a ia in te r rio r 2116a, 2216b, 2116 c, 2116d. Therefore, as shown in Fig. 24B, the r e rcom p e rim e of the in te r rio r 21 06 pe rm ete, pe ro re s the ro tation of co ntact 1212 with re sp e ct to th e te ation to th e ro u tion 2102.
