    RELATED ORDER
    [0001] The present application claims the benefit of Provisional Patent Application US 61 / 719,634, filed on October 29, 2012, the disclosure of which is incorporated herein by reference. FIELD
    [0002] The present application relates generally to wheels and, more generally, to collapsible wheels and methods for manufacturing collapsible wheels. FUNDAMENTALS
    [0003] Some sports equipment may require a wheeled vehicle for transportation. For example, kayaks can be transported to a river or lake in a wheeled kayak cart. Before launching the kayak into the water, the kayak cart is removed from the kayak and can be stored in the kayak. The kayak cart may have a structure that is collapsible to reduce the cart size when not in use. In another example, an individual playing golf can carry his golf bag on his shoulder, with a pull golf cart or an electric golf cart. Golf traction carts typically have a structure in which two wheels for moving the cart are attached. The frame may also include a handle that is retained by an individual to balance, pull or push the cart and a platform or base to support the individual's golf bag. The frame can be collapsible to reduce the size of the pull cart when not in use for storage and / or transportation. BRIEF DESCRIPTION OF THE DRAWINGS

    [0031] With reference to FIGS. 1 and 2, a wheel 100 according to an example of the apparatus, methods and articles of manufacture described herein is shown. Wheel 100 includes a hub assembly 102 and a tire 104, at least a portion of which is mounted around hub assembly 102 for contact with the ground. Wheel 100 also includes an axle 106 on which hub assembly 102 is rotatably mounted. A wheel 100 or a plurality of wheels 100 can be used on a cart or vehicle to transport any object.
    [0032] FIG. 1 shows wheel 100 in an expanded position. To reduce the size of the wheel 100 for transportation and / or storage, an individual can collapse the wheel 100 to a collapsed position shown in FIG. 2. For example, an automobile trunk may not have enough space to accommodate a golf club pull cart when the pull cart wheels 100 are in the expanded position. By placing the wheels 100 in the collapsed position, the pull cart and wheels 100 can fit in the trunk of the car for transportation. Therefore, the collapse of the wheels from an expanded position to a collapsed position allows the wheels and / or any object to which the wheels are attached to take up less space. In addition, as discussed in detail below, each wheel 100 can be removable from a cart to further reduce the space that can be occupied by the cart and wheels 100.
    [0033] With reference to FIGS. 3 to 6, the hub assembly 102 is shown in the expanded and collapsed positions, respectively. Hub assembly 102 includes a plurality of stacked wheel sections 110. Each wheel section 110 includes a hub section 112 with a central hole 114. Wheel sections 110 can be stacked concentric so that the central holes 114 are axially aligned to form an elongated hole to receive the shaft 106. Each wheel section 110 can include at least one spoke 116 and a rim 118. In the example of FIGS. 1 to 5, each wheel section 110 has a first pair of spokes 116 that protrudes radially from hub section 112 to connect to a first rim 118 and a second pair of spokes 116 that protrudes radially from hub section 112 opposite the first pair of spokes 116 to connect to a second rim 118. Each rim 118 receives and supports a section of tire 104. Each wheel section 110 can include any number of spokes 116 that extend from hub section 112 to one or more rims 118. For example, each ring 118 can be connected to only one ray 116 or a plurality of rays 116. Rays 116 can be of any shape. For example, each radius 116 may be straight, curved at one or more locations along the length of the radius and / or have a curvature. In the examples of FIGS. 1 to 5, spokes 116 can be curved so as to function as springs when wheel 100 is used. Therefore, when forces are exerted on the rim 118 during operation of the wheel 100, the curved shape of each spoke 116 facilitates the elastic folding of spoke 116, so that spoke 116 provides a shock absorbing function.
    [0034] Each wheel section 110 can be freely rotatable about the axis 106, to allow expansion of the wheel sections 110 from a collapsed position shown in FIG. 4 to an expanded position shown in FIG. 3. The number of wheel sections 110, the thickness of each wheel section 110 and / or the radial extent of each wheel section 110 can be determined so that, in the expanded position of wheel 100, a complete circular wheel, i.e. ie, about 360 °, is defined by wheel 100 and the rims 118 provide sufficient support for tire 104 for proper operation of wheel 100. Providing sufficient support for tire 104 at any time during operation of wheel 100 can be defined by the number of points of contact between the wheel 100 and the ground. Each rim 118 can be defined as having a contact point which, although here referred to as a contact point, can represent an area of rim 118 which contacts the ground. Increasing the number of points of contact between the wheel 100 and the ground can increase the stability of the wheel 100, hence increasing the stability of the vehicle, that is, a pulling cart, to which the wheel 100 is attached.
    [0035] The radial extent of each wheel section 110 can determine the radial position of each wheel section 110 with respect to an adjacent wheel section 110 in the expanded position of wheel 100 and the number of wheel sections 110 that may be required . Radial extension 119, as shown in FIG. 5 and as used herein, you can generally define a rim length 118 that contacts the ground during operation of the wheel 100. For example, if each rim 118 of a pair of rims 118 of a wheel section 110 defines a radial extension of fence at 90 °, only two wheel sections 110 may be necessary, so that the rims 118 define a full circle or about 360 ° without generally any overlap or gap between two adjacent rims 118; or each rim 118 can generally define a radial extension of 90 ° in a complete circle defining the wheel 100. In other words, each wheel section 110 can generally define a radial extension of 180 ° in a complete circle defining the wheel. In another example, if each rim 118 of a pair of rims 118 of a wheel section 110 has a radial extension 119 of about 45 °, four wheel sections 110 may be required, that is, eight rims 118, so that the rims 118 define a full circle or about 360 ° without generally any overlap or gap between two adjacent rims 118. Therefore, a general configuration of the wheel 100 can be defined by the following example equation: - C = R (1) NW
    [0036] where W represents the number of wheel sections, N represents the number of opposing rims 118 on each wheel (for example, N is 2 in the example of FIGS. 2 to 5), C represents the number of contact points in the ground and R represents the radial spacing of each wheel section in relation to an adjacent wheel section (in degrees).
    [0037] As described above, increasing the number of contact points between the wheel 100 and the ground can increase the stability of the wheel 100. Each rim 118 can contact the ground at a contact point. By providing multiple points of contact, i.e., multiple rims 118 that contact the ground at any time, the stability of the wheel 100 can increase. In other words, increasing the number of points of contact with the ground at any time during the operation of the wheel 100 increases the width of the wheel 100, thereby increasing the number of wheel sections 110 that can be used to form the wheel 100 .
    [0038] With reference to FIG. 5, an example of the wheel 100 is shown, where each wheel section has a rim 118 which has a radial extension 119 of about 45 °. Therefore, adjacent wheel sections 110 can generally be spaced radially by about 45 ° in the expanded position of wheel 100, as shown in FIG. 5. In the example of FIG. 5, four wheel sections 110, i.e., eight rims 118, would be required to define a full circle or about 360 °. Thus, if wheel 100 is constructed with four wheel sections 110, only one rim 118, that is, a point of contact, contacts the ground at any time. To increase the stability of the wheel 100, sixteen wheel sections 110 can be provided as shown in the example of FIG. 4, so that at any time during the operation of the wheel 100, four points of contact on the wheel 100 contact the ground, that is, four rims 118 define the width of the wheel 100. Any number of wheel sections 110 can be provided for increase or reduce contact points. For example, twenty wheel sections 110 would provide five points of contact with the ground at any time for wheel 100. In another example, twelve wheel sections 110 would provide three points of contact with the ground. According to the above, when each rim 118 extends for about 45 °, at least eight hoops 118 may be required, so that at any time during the operation of the wheel 100 a contact point contacts the ground. To increase the number of contact points along the width of the wheel, when each rim 118 has a radial extension 119 of about 45 °, multiples of four wheel sections 110 can be provided. In the example of FIG. 4, sixteen wheel sections 110 for wheel 100 provide four points of contact at any time during wheel operation as shown in FIG. 6.
    [0039] Increasing the number of wheel sections 110 may increase the stability of the wheel 100 and / or the amount of weight that the wheel 100 can support. However, increasing the number of wheel sections 110 can also increase the size and / or weight of the wheel 100 in the collapsed position. Therefore, the size of each wheel section 110 and other properties of each wheel section 110, as described herein, can be determined depending on the size and load of the cart to which one or more wheels 100 can be attached.
    [0040] FIG. 6 illustrates an expanded position of two wheel sections 110. The rim 118 of each wheel section 110 includes a radial projection 120. With reference to FIGS. 7 to 11, tire 104 may include an inner surface 130 and an outer surface 132. The outer surface 132 may be smooth or threaded. The inner surface 130 can have any configuration to provide support for the tire 104 in the rims 118. In the examples of FIGS. 8 and 9, the inner surface 130 includes a plurality of generally parallel ribs 134 that define a plurality of generally parallel grooves 136 between the ribs 134. Ribs 134 and grooves 136 may radially span a portion of the inner surface 130. In the examples of FIGS. 8 and 9, the ribs 134 and the grooves 136 extend over all 360 ° of the inner surface 130 of tire 104.
    [0041] With reference to FIGS. 10 and 11, the distance between adjacent grooves 136 generally corresponds to the distance between the projections 120 of adjacent wheel sections 110. In addition, the cross-sectional shape of each groove 136 can generally correspond to the cross-sectional shape of the projections 120. Therefore when tire 104 is mounted on wheel sections 110, projections 120 can engage grooves 136 and generally fit into grooves 136. Projections 120 and grooves 136 can have any shape of cross section. In the example of FIG. 11, the projections 120 are shown to have a generally triangular cross-sectional shape and the grooves 136 are also shown to have a corresponding triangular cross-sectional shape. In addition, the size of the grooves 136 can generally correspond to the size of the projections 120. For a tire 104 that is constructed of an elastic material, such as rubber, the grooves 136 can alternatively be formed to be smaller than the projections 120, of so that the grooves 136 elastically expand when receiving the projections 120 to provide an engagement generally forming shape with the projections 120. The tire can be attached to one or more of the rims 118, so that the tire is kept in a wheel-mounted configuration 100 in both the collapsed and expanded positions of the wheel 100.
    [0042] As described above, each wheel section 110 can be positioned relative to an adjacent wheel section 110 at a certain angle during the operation of the wheel 100 to provide a sufficient number of contact points and generally contact point locations. evenly distributed to wheel 100. For example, wheel sections 110 of FIG. 5 are positioned at about 45 ° to each other in the expanded position to provide four contact points evenly distributed at any time during the operation of the wheel 100. The angle between the wheel sections 110 in the expanded position provides a sufficient number of contact points and generally evenly distributes the contact point locations on the wheel can be referred to here as the expansion angle. The expansion angle is shown in equation (1) as the variable R. Thus, the expansion angle for the example in FIG. 5 is about 45 °.
    [0043] As described in detail above and with respect to equation (1), the expansion angle may be different depending on the configuration and / or properties of the wheel sections 110. To limit the expansion of the wheel sections 110 with respect to one each other and / or to provide positioning of the wheel sections 110 relative to each other at the expansion angle, the wheel 100 may include an expansion angle limiting mechanism by which the rotation of each wheel section 110 with respect to a adjacent wheel section 110 is limited to the expansion angle. According to an example shown in FIG. 12, the angle limiting mechanism includes a radial slot 140 in the hub section 112 of each wheel section 110 and a pin 144 that can be located in the hub section 112 opposite the slot 142 in relation to the central hole 114. The length of the arc of each radial slot 140 can generally be no greater than the expansion angle. In the example of FIG. 12, the arc length of the radial slot 140 is about 45 ° which is the same as the expansion angle. When wheel sections 110 are assembled as described in detail below, that is, stacked on top of each other, pin 144 of each wheel section 110 is placed within slot 140 of an adjacent wheel section 110. Therefore, when adjacent wheel sections are rotated relative to each other, pin 144 moves in slot 140. However, the radial movement of pin 144 which defines the radial movement of wheel section 110 having pin 144, is limited by the arc length slot 140.
    [0044] Each slot 140 includes a first end 150 and a second end 152. In the collapsed position of wheel 100, pin 144 of each wheel section 110 is located near the first end 150 of slot 140 of an adjacent wheel section 110 As the wheel 100 is expanded, the pin 144 moves in the slot 140 of the first end 150 until the pin 144 contacts the second end 152 of the slot 140. Thus, the slot 140 limits the rotation of the two adjacent wheel sections 110 in with respect to each other the expansion angle or radial arc length of the slot 140. The position of each slot 140 and the pin 144 can be determined to allow expansion and collapse of the wheel 100 as disclosed. In the example of FIG. 12, the first end 150 of the slots 140 is generally located along a central longitudinal axis 154 of the hub section 112. Consequently, the second end 152 of the slot 140 is located about 45 ° from the first end 150. The pin 144 it is also located on the central longitudinal axis 154, but is located opposite the first end 150 of the slot 140 with respect to the central hole 114. As described in detail below, the arrangement of pin 144 and slot 140, as shown in FIG. 12 allows each wheel section 110 to be rotated with respect to an adjacent wheel section by the expansion angle.
    [0045] After the wheel 100 is expanded, which is defined by each wheel section 110 having the expansion angle relative to an adjacent wheel section 110, the wheel 100 can be held in the expanded position by any type of latch, locking and / or similar mechanisms that prevent the wheel sections 110 from rotating with respect to each other. For example, each wheel section 110 may include an opening (not shown) positioned in hub section 112 so that when wheel sections 110 are in the expanded position of wheel 100, all openings in wheel sections 110 are generally aligned to receive a rod (not shown). Accordingly, the rod prevents the wheel sections 110 from rotating with respect to each other. In another example, a U-shaped support (not shown) which has a width that is generally similar to the collective width of cube sections 112 can be placed over cube sections 112 to prevent cube sections 112 from rotating relatively each other.
    [0046] With reference to FIGS. 13 and 14, the wheel sections 110 can be rotatably mounted on an axis 106. The axis 106 can be defined by a cylindrical axis 160 having a first end 162 and a second end 164. In the example of FIGS. 13 and 14, the shaft 106 may further include a mounting bracket 166 having a first support section 168 and the second support section 170. The mounting bracket 166 may facilitate the mounting or fixing of the wheel 100 to a cart, such as like a golf cart. The wheel sections 110 can be mounted on the axis 160 by inserting the axis 160 from the first end 162 of the central hole 114 of each wheel section 110. The axis 106 may include a mechanism by which the first wheel section 110 is mounted on the axis 160 it is kept stationary to allow expansion of the wheel 100 from a collapsed position. In one example, as shown in FIG. 13, the first support section 160 includes a pin hole 170 for receiving pin 144 of the first mounted wheel section 110. The engagement of pin 144 in pin hole 170 of the first mounted wheel section 110 maintains the first wheel section mounted 110 attached to the first support section 160 to allow expansion of the wheel 100 from a collapsed position to an expanded position. After the wheel 100 is expanded, the pin 144 can be removed from the pin hole 170 to allow rotation of the wheel 100 about the axis 160.
    [0047] The axle 106 may further include a wheel retention mechanism by which the wheel 100 is maintained on the axis 160 during operation of the wheel 100. The wheel retention mechanism may include any configuration to prevent the wheel 100 from sliding to off axis 106 or removed from axis 106 during operation of wheel 100. For example, the first end 162 of axis 160 can be threaded to receive a correspondingly threaded nut (an example is shown in FIG. 22. The nut thread increases the diameter of the shaft 160 at the first end 162 to a diameter that is larger than the central holes 114 of the hub sections 112. In this way, the wheel sections 110 are stopped by the nut when reaching the first end 162 of the shaft 160 .
    [0048] In the example of FIG. 13, axis 160 includes an annular recess 172 at or near the first end 162 of axis 160. As shown in FIG. 14, after the wheel sections 110 are mounted on the axis 160, an elastic clamp 174 can be mounted and pressed on the axis 160, so that the elastic clamp 174 engages and remains in the annular recess 172. The elastic clamp 174 increases the diameter of the axis 160 at the first end 162 to a diameter that is greater than the diameters of the central holes 114 of the hub sections 112. In this way, the wheel sections 110 are stopped by the elastic clamp 174 when reaching the first end 162 of the axis 160 The shaft 106 may also include a washer 176 or the like mounted between the elastic clamp 174 and the last mounted wheel section 110. To provide easier installation of the elastic clamp 174 in the annular recess 174, the first end 162 of the shaft can be tapered , as shown in FIGS. 13 and 14, so that the pressing of the elastic clip 174 at the first end 162 gradually expands the elastic clip 172 when mounted on the axis 160. Thus, the elastic clip 174 remains engaged in the annular recess 172 until it is expanded with or without a tool by an individual to remove the elastic clip 174 from the shaft 160, which then allows removal of the wheel sections from the shaft 160. At the second end 164 of the shaft 160 an annular shoulder 178 can be provided, so that the first mounted wheel section 110 is spaced from the first support section 168.
    [0049] FIG. 2 shows wheel 100 in the collapsed position with tire 104 mounted thereon. Tire 104 may be constructed of an elastic material, such as rubber. In addition, the inner diameter of the tire 104 may be less than an outer diameter of a circle defined by the wheel 100 in the expanded position. In this way, the tire can be easily mounted on the wheel 100 in the collapsed position. However, tire 104 can expand elastically when wheel 100 is expanded. The elastic expansion of tire 104 can create a restoring force on tire 104 by which tire 104 is pressed into rims 118 (for example, projections 120 are pressed into grooves 136) to keep tire 104 on wheel 100 during operation of the tire wheel 100.
    [0050] To expand the wheel 100 from a collapsed position to the expanded position, each of the wheel sections 110 can be rotated manually. In one example, shown in FIGS. 15 and 16, wheel 100 includes a hub cap 200 by which the wheel sections 110 can be rotated with respect to each other to expand wheel 100. Hub hub 200 can include two opposite handles 202 and 204 that can be retained by an individual to rotate hub cover 200. Hub cover 200 may include a pin (not shown) on an internal surface thereof that can engage within slot 140 of the last assembled wheel section 110. Hub cover 200 can be rotatably mounted on shaft 106. Therefore, when hub cover 200 is rotated around shaft 106 by an individual, the pin on the inner surface of hub cover 200 moves in slot 140 of the first wheel section 110 to the pin engages the second end 152 of the slot 140. After the first wheel section 110 is rotated at the expansion angle, the pin 144 of the first wheel section 110 engages the second end 152 with the slots 140 of the second wheel section 110, as described above. Therefore, the further rotation of the hub cap 200 causes the second wheel section 110 to rotate with respect to the third wheel section 110 at the expansion angle. Continuing the rotation of hub cap 200 rotates the remaining wheel sections 110 until wheel 100 is fully expanded. The hub cap 200 can be mounted on the axis 160 between the last mounted wheel section 110 and the elastic clamp 174. When holding handles 202 and 204, an individual can also hold the second support section 166 to provide leverage when expanding the wheel 100.
    [0051] FIGS. 17 and 18 show a wheel 400 according to another example. Wheel 400 is similar in some respects to wheel 100. Therefore, similar parts of wheel 100 and wheel 400 are referred to with the same reference numbers. The wheel 400 includes a plurality of wheel sections 110 that are mounted on an axis 406 (shown in FIG. 17). Axis 406 includes a first end 462 (shown in FIG. 17) and a second end (not shown). The axle 406 receives the wheel sections 110 by being inserted into the central holes 114 of the wheel sections 110. The second end of the axis 406 includes a base 470 which is larger in diameter than the diameter of the central hole 114 of the wheel sections 110 Therefore, when wheel sections 110 are mounted on axle 406, wheel sections 110 are attached to the second end of the axle by base 470. To prevent wheel sections 110 from being removed from axle 406 during wheel operation 400, the second end 462 of shaft 406 can be threaded to receive a correspondingly threaded screw 480. Thus, tightening the screw 480 at the first threaded end 462 on the shaft 406 prevents the wheel sections 110 from being removed from the shaft 406 during the operation of the wheel 400. Alternatively, the wheel 400 may include a wheel retention mechanism similar to the mechanism wheel retention wheel 100, as described in detail above. Wheel 400 includes a hub cap 200, which can be used to expand wheel 400 from the collapsed position to the expanded position as described in detail above with respect to wheel 100.
    [0052] With reference to FIG. 18, the first mounted wheel section 110 may include two opposing handles 502 and 504 on the central hub section 112 which are similar in position to handles 202 and 204 of hub cover 200. In this way, an individual can expand wheel 400 of the collapsed position holding handles 202 and 204 with one hand and turning handles 202 and 204 in one direction and holding handles 502 and 504 with the other hand and turning handles 502 and 504 in the opposite direction to rotate the wheel sections relative to one the other to expand wheel 400 to the expanded position. Handles 502 and 504 can be part of a hubcap (not shown) that is mounted on shaft 406 before the first wheel section 110 is mounted on shaft 406. Alternatively, as shown in FIGS. 17 and 18, handles 502 and 504 can be an integral part of the first assembled wheel section 110.
    [0053] With reference to FIGS. 19 and 20, a wheel 600 according to another embodiment is shown. The wheel 600 is similar in some respects to the wheels 100 and 400. Therefore, similar parts of the wheels 100, 400 and 600 are designated with the same reference numbers. Wheel 600 includes a plurality of wheel sections 610. Each wheel section 610 includes a hub section 612 with a central hole (not shown). Each wheel section 610 includes a pair of generally straight spaced spokes 616 on each side of the perimeter section of hub section 612 that protrudes radially outward and connects to a generally curved rim 618. The distance between each pair of spokes 616 can increase from hub section 612 to rim 618. Thus, each pair of spokes 616 and the corresponding rim 618 define a generally trapezoidal shape. The wheel 600 includes an axle 606 that is mounted through the central holes of the wheel sections 610. The axle 606 and the mechanisms and methods by which the axle 606 is operationally connected to the wheel and the cart are similar to the axle 106 and 406. For therefore, a detailed description of axis 606 is not provided.
    [0054] With reference to FIGS. 21 to 25 a wheel 800 according to another example is shown. Wheel 800 includes a hub assembly 802 and a tire (not shown) that is mounted to hub assembly 802 as described below. Wheel 800 also includes an axle 806 on which hub assembly 802 and a tire are rotatably mounted. Hub assembly 802 includes a plurality of wheel sections 810 that are concentric mounted on the shaft 806. Each wheel section 810 includes a hub section 812 having a central bore 814 for receiving a shaft section 806.
    [0055] The tire can be mounted on a plurality of rims 818 which are positioned along a perimeter of a circle 817 that defines a central plane of the wheel 800. Each rim 818 is generally oriented perpendicular to circle 817 (shown in FIG. 24 ) and is convex in relation to hub sections 812. In this way, each rim 818 is concave with respect to the tire (not shown), in order to receive a curved section of the tire. Each rim 818 is attached to two hub sections spaced 812 by two spokes 816, respectively. The two hub sections 812 to which a rim 818 is attached with spokes 816 are spaced apart, so that spokes 816 form a V-shaped support for each rim 818. For example, as shown in FIG. 22, the spokes 816 supporting a rim 818 are connected to hub sections 812 are spaced by five hub sections 812. Thus, each hub section 812 has a radius 816 on one side of it that partially supports a first corresponding rim 818 and another radius 816 on the opposite side of it which partially supports a second corresponding rim 818.
    [0056] FIGS. 23 to 25 show the expanded position of wheel 800. Spokes 816 are positioned in hub sections 812, such that when wheel 800 is in the expanded position, spokes 816 are evenly distributed around the wheel, that is, radially spaced in circle 817 at a similar expansion angle. In the example of FIGS. 23 to 25, spokes 816 are shown to be generally 30 ° apart in the expanded position of wheel 800. FIGS. 21 and 22 show the collapsed position of the wheel 800. To collapse the wheel 800, the hub sections 812 can be rotated relative to each other until the rims 818 contact each other and prevent further rotation of the hub sections 812. To expand the wheel 800, the hub sections 812 can be rotated in an opposite direction with respect to each other, such that the wheel 800 reaches the expanded position shown in FIG. 23. Since each spoke 816 is located in a different hub section 812, wheel 800 may require less than 180 ° rotation to expand from the collapsed position to the expanded position. Therefore, to expand the wheel 800 from the collapsed position as shown in FIG. 21, radius 820 is rotated clockwise until radius 820 is positioned close to radius 822 and is prevented from further rotation by an expansion limiting mechanism, as described below. Simultaneously, radius 824 is rotated clockwise until it is positioned close to radius 826 and is prevented from further rotation by the expansion limiting mechanism. Thus, the largest rotation of the hub section 812 can be less than 180 ° to expand the wheel from the collapsed position to the expanded position.
    [0057] To prevent further rotation of the hub sections 812 relative to each other when the wheel 800 reaches the expanded position shown in FIG. 23, the wheel 800 may include an expansion limiting mechanism, as described above. In this way, each wheel section 810 can include a radial slot (not shown) in hub section 812 and a pin (not shown) that can be located in hub section 812 opposite the slot in relation to central hole 814. The length of the arc of each radial slot 140 can generally be no greater than the expansion angle. In the example of FIGS. 24, the arc length of the radial slot is about 30 ° which is the same as the expansion angle.
    [0058] A tire (not shown) can be fitted to wheel 800 before or after the wheel is expanded. The tire may be constructed of a solid piece of rubber or other type of plastic material that has sufficient elasticity to allow the tire to be fitted to the 800 wheel. Alternatively, the tire may be in the form of an inflatable tube that can be fitted to the rims 818 Consequently, the tire can be inflated by an individual before operating the wheel 810. Alternatively, the tire can be attached to one or more of the rims 818, so that the tire is kept in a configuration mounted on the wheel 800 on both sides. collapsed and expanded positions of wheel 800.
    [0059] FIGS. 26 to 33 show several sample wheels and / or wheel sections according to the disclosure. A wheel section 1010, as shown in FIG. 26 can include at least one spoke 1016 on each side of a hub section 1012. Wheel section 1010 also includes at least one rim 1018 attached to each spoke 1016. Each spoke 1016 and the corresponding rim 1018 generally define a spoke set and T-shaped rim. A wheel section 1010, as shown in FIG. 27 can include at least one spoke 1116 on each side of a hub section 1112. Wheel section 1110 also includes at least one rim 1118 attached to each spoke 1116. Each spoke 1116 and the corresponding rim 1118 generally define a spoke set and L-shaped rim According to exemplary wheel sections 1010 and 1110, at least one rim and at least one spoke can be attached to each other in any configuration. For example, an end of a spoke can be attached to a center of the rim length, as shown by wheel section 1010, to provide a T-shaped spoke and spoke assembly in general. With the exemplary wheel section 1110, however, the spoke end is attached to one end of the rim. Therefore, a radius and a rim can be attached to each other in any configuration and with any type of displacement in relation to each other.
    [0060] FIGS. 28 and 29 show a 1200 wheel according to another example. Wheel 1200 includes a plurality of wheel sections 1210, where each wheel section 1210 can have a different configuration compared to one or more of the other wheel sections 1210. For example, each wheel section 1210 can have spokes in different shapes. 1216. Spokes 1216 can be straight, curved, L-shaped, Z-shaped and / or any other shape that may be different from spokes 1216 of one or more of the other wheel sections 1210. Depending on the shape of each spoke 1216, each spoke may have a different thickness, be constructed of a different material and / or have a certain property that may be different or similar to one or more other spokes 1216 from one or more other wheel sections 1210. A tire 1204 can be mounted on wheel 1200 in either the collapsed or expanded position of wheel 1200.
    [0061] FIGS. 30 and 31 show a wheel 1300 according to another example. The wheel 1300 includes a plurality of spokes 1316. Each spoke can be flexible so as to deform from an expanded position corresponding to the expanded position of the wheel 1300 to a deformed position corresponding to the collapsed position of the wheel 1300. FIG. 30 shows an example of wheel 1300 in the process of being expanded between the collapsed position and the expanded position shown in FIG. 31. In the extended position of spokes 1316 as shown in FIG. 31, spokes 1316 have sufficient collective stiffness to withstand the loads on tire 1304 and hub assembly 1302, to provide operation of wheel 1300, as disclosed. However, spokes 1316 are flexible, so that wheel 1300 can be collapsed by deforming spokes 1316 to collapse wheel 1300. As shown in the example of FIG. 30, spokes 1316 can be deformed by being folded and stacked on top of each other around hub 1312. spokes 1316 can also provide a shock absorbing function for wheel 1300. Wheel 1300 may include a single hub 1312 to which all flexible spokes 1316 are attached. Alternatively, the wheel 1300 may include a plurality of hub sections, each hub section rotating with respect to an adjacent hub section to facilitate the collapse and expansion of the wheel 1302 to which one or more spokes 1316 can be attached. . As shown in FIGS. 30 and 31, the wheel 1300 may also include a tire 1304 which may be similar to the exemplary tires disclosed herein.
    [0062] FIGS. 32 and 33 show a wheel 1400 according to another example. The wheel 1400 includes a hub 1412 to which the rim 1418 is attached. The rim 1418 includes a first rim section 1420 and a second rim section 1422 that are pivotally mounted to hub 1412 by one or more hinges 1424. As shown in FIG. 33, the first rim section 1420 and the second rim section 1422 can be pivoted on hinge 1424 to collapse wheel 1400 from the expanded position shown in FIG. 32 to a collapsed position (not shown). Thus, the wheel size 1400 can be reduced for storage and / or transportation by collapsing the wheel from the expanded position.
    [0063] With reference to FIG. 34, a section of a wheel 1500 according to another example is shown. Wheel 1500 includes at least one spoke 1516 and at least one rim 1518 that is attached to spoke 1516. Wheel 1500 may not include a one-piece tire similar to the examples described above. Instead, a tire section 1504 is attached to each rim 1518. Therefore, when wheel 1500 is expanded to an expanded position, tire sections 1504 collectively define a tire for wheel 1500. Therefore, the tire stops the wheel 1500 is defined by a plurality of tire sections 1504 and any clearances that may be present between adjacent sections of tire 1504. As with the examples described above, the tire section 1504 can be constructed of an elastic material, such as rubber . The tire sections 1504 can then be attached to a rim 1518 with an adhesive, one or more fasteners and / or one or more other types of fixing devices or procedures.
    [0064] With reference to FIGS. 35 to 41, a wheel 1600 according to another example is shown. Wheel 1600 includes a hub assembly 1602. Wheel 1600 may include a tire (not shown) that can be mounted on hub assembly 1602. Alternatively, wheel 1600 may include a plurality of tire sections as described above with respect to wheel 1500. Alternatively, the wheel 1600 can operate without a tire. Wheel 1600 also includes an axle 1606 on which hub assembly 1602 is rotatably mounted. Hub assembly 1602 includes a plurality of wheel sections 810 that are concentrically mounted on shaft 1606. Each wheel section 1610 includes hub section 1612 having a central bore 1614 for receiving a shaft section 1606.
    [0065] The wheel 1600 includes a plurality of rims 1618 which are configured to define a path in a circumferential or circular strip 1617 having a width 1619. The path defined by the rims 1618 can be substantially continuous. Circular band 1617 defines a tire-like circular contact area (shown in FIG. 38) between wheel 1600 and the ground. In the expanded position of the wheel 1600, each rim 1618 can be oriented in such a way that at least one point on at least one rim 1618 contacts the ground. In one example, each rim 1618 is positioned diagonally in the circular band 1617. Each rim 1618 can be spaced radially from an adjacent rim 1618, as long as the space does not provide a gap large enough to disturb or substantially prevent the smooth roll of the wheel 1600 on the ground. Alternatively, each rim 1618 may not have a radial clearance with respect to an adjacent rim 1618. Alternatively, each rim 1618 may have a radial overlap with an adjacent rim 1618. In the example of FIG. 38, each ring 1618 has a small gap in relation to an adjacent ring 1618. Each ring 1618 can also be curved so as to point to adjacent rings 1618 that are spaced apart at a certain angle are located in the circular band 1617. As shown in FIG. 35, rim 1618 defines a portion of a path in a continuous circle generally at the expanded position of wheel 1600. In other words, the curvature of each rim 1618 can generally follow the curvature for the circle that defines a plane of wheel 1600.
    [0066] Each rim 818 is fixed to two hub sections spaced 1612 by two spokes 1616, respectively. The two hub sections 1612 to which a rim 1618 is attached with spokes 1616 are spaced apart so that spokes 1616 form a V-shaped support for each rim 1618. For example, as shown in FIG. 41, spokes 1616 that support a rim 1618 are connected to hub sections 1612 that are spaced by four hub sections 1612. Thus, each hub section 1612 has a radius 1616 on one side of it that partially supports a corresponding first rim 1618 and another radius 1616 on the opposite side of it which partially supports a second corresponding ring 1618.
    [0067] FIGS. 35, 36 and 38 show the expanded position of the wheel 1600. The spokes 1616 are positioned in the hub sections 1612, such that when the wheel 1600 is in the expanded position, the spokes 1616 are evenly distributed around the wheel, i.e. , radially equally spaced at a similar expansion angle. In the example of FIG. 35, spokes 1616 are shown to be generally 30 ° apart from each other in the expanded position of wheel 1600. FIGS. 37, 39 and 40 show the collapsed position of the wheel 1600. To collapse the wheel 1600, the hub sections 1612 can be rotated relative to each other until the rims 1618 contact each other and prevent further rotation of the hub sections 1612. Each spoke 1616 can have a certain cross-sectional shape to provide a more compact collapsed position for the wheel 1600. For example, each spoke 1616 can have a diamond-shaped cross section, as shown in FIG. 41. Therefore, when the wheel 1600 is collapsed, each spoke 1616 can be positioned in relation to an adjacent spoke 1616 in a complementary or suitably shaped manner. Therefore, rays 1616 can collectively occupy less space compared to a scenario in which each ray 1616 has a certain shape that does not lend itself to such a complementary fit with an adjacent ray 1616.
    [0068] To expand the wheel 1600, the hub sections 1612 can be rotated in an opposite direction to each other, such that the wheel 1600 reaches the expanded position 1612. As each radius 1616 is located in a different hub section 1612, wheel 1600 may need a rotation less than 180 ° to expand from the collapsed position to the expanded position as described in detail with respect to wheel 800, hence it is not repeated here. Thus, the greatest rotation of a hub section 812 can be less than 180 ° to expand the wheel 1600 from the collapsed position to the expanded position.
    [0069] To prevent further rotation of the hub sections 812 relative to each other when the wheel 1600 reaches the expanded position, the wheel 1600 may include an expansion limiting mechanism, as described above. Accordingly, each wheel section 810 can include a radial slot (not shown) in hub section 1612 of 1612 and a pin (not shown) that can be located in hub section 1612 opposite the slot in relation to central hole 1614. The arc length of each radial slot can generally be no greater than the expansion angle.
    [0070] Similar to the example in FIG. 34, each 1618 rim may include a tire section (not shown) that is attached to each 1618 rim. For example, each tire section (not shown) may be a generally rectangular strip of rubber or similar elastic materials that is attached to each rim 1618 along the length of rim 1618. Thus, each tire section generally follows the orientation and spatial position of each rim 1618 in the circular band 1617, as described above. Therefore, when the 1600 wheel is expanded to an expanded position, the tire sections collectively define a tire for the 1600 wheel. As with the examples described above, a tire section 1504 can be constructed of an elastic material, such as rubber . The tire sections can then be attached to a 1618 rim with an adhesive, one or more fasteners and / or one or more other types of fixing devices or procedures.
    [0071] A tire (not shown) can be fitted to the 1600 wheel before or after the wheel is expanded. The tire may be constructed of a solid piece of rubber or another type of plastic material that has sufficient elasticity to allow the tire to be fitted to the 1600 wheel. Alternatively, the tire may be in the form of an inflatable tube that can be fitted to the 1618 rims Alternatively, the tire may be attached to one or more of the 1618 rims, so that the tire is maintained in a configuration mounted on the wheel 1600 in both the collapsed and expanded positions of the wheel 1600.
    [0072] With reference to FIG. 42, a 1700 method for building a wheel according to an example is shown. The method comprises forming a plurality of wheel sections (block 1702) and mounting the wheel sections on an axle (block 1704). The 1700 method may also include forming a tire (not shown) and / or mounting or attaching a tire to the wheel sections (not shown). A wheel according to the disclosure can be constructed of any metal or metal alloys, plastic, composite materials, wood or a combination of these. For example, each wheel section, like the wheel sections 110 of the wheel 100, can be formed in one piece of a plastic material by injection molding. In an injection molding process, a mold can be used that has a cavity that defines a wheel section. Molten plastic material is injected into the mold and cooled. The molded and cooled wheel section is then removed from the mold. The molded wheel section can also be smoothed or cleaned to remove injection molding residues. Alternatively, a wheel section can be constructed by stamping (ie, drilling using a machine press or a stamping press, blanking, engraving, folding, flanging, coining or casting), forging, machining or a combination thereof , or other processes used to manufacture metal, composite, plastic or wood parts. Each wheel section can be formed in one piece. Alternatively, components of each wheel section can be formed by processes and materials described herein and assembled to form the wheel section. For example, wheel section 110 can be formed by assembling a separately manufactured hub section 212, spokes 216 and rim 218. A hub section 212, one or more spokes 216 and a rim 218 can be attached to each other by one or more than adhesives, welding, welding and / or fasteners. The disclosed materials and / or processes can be used to manufacture any of the disclosed wheel, axle and / or tire components. A tire can be made of an elastic material to provide shock absorption for a push cart to which one or more of the disclosed wheels are attached. A tire can be formed of rubber or other plastic materials. A tire can be formed as an inflatable tube or a flexible solid material.
    [0073] With reference to FIG. 43, a 1800 golf cart to support and carry a golf club bag is shown to have 100 wheels. Although the 1800 golf cart is shown with wheels 100, any of the wheels described here can be used with a golf cart pull. Golf cart 1800 may include a frame 1810 on which a golf club bag (not shown) can rest. The golf club bag can also be supported by a lower support 1812, a lower side support 1813 and an upper side support 1814. The frame 1810 can also include one or more straps (not shown) for attaching a golf club bag in frame 1810. Puller 1800 may further include two feet 1820 in 1822 extending out of frame 1810 opposite each other. Each foot supports a wheel 100. The frame may also include a hinge 1824 having two hinge rods 1826 and 1828 through which the feet 1820 in 1822 can be hinged and collapsed so that the feet 1820 and 1822 extend along the frame 1810. The 1810 frame can also collapse on the hinge to provide a compact 1800 golf cart for transport to and from a golf course, driving range or any golf related facility. A collapsed golf pull cart 1800 is shown in FIG. 44. To further reduce the size of the 1800 golf cart, wheels 100 can be collapsed as described in detail here. In addition, wheels 100 can be removed from the push cart 1800 and stored separately. Thus, the use of wheels 100 or any of the wheels described herein can reduce the size of any vehicle, such as a golf cart, for easier storage and / or transportation. Alternatively, a golf club bag (not shown) can include attachment points or axles to directly attach two collapsible wheels as described here in detail to the golf club bag. For example, a golf club bag can be provided with two collapsible wheels that can be stored in one or more golf club bag pockets. An individual can carry the golf club bag or attach the two wheels to an axle in the golf club bag, expand the wheels and pull the golf club bag using the wheels. The use of collapsible wheels, as described in detail in this document, is not limited to golf pulling carts. Collapsible wheels as described in detail in this document can be used for kayak carts, candy carts, small cars that are typically used by children, any type of luggage, luggage carts, coolers and / or any other wheeled utility cart, trailer , closed storage device or a vehicle.
