ROD PROVIDING EXTRUSION DRAWING MATERIAL
TECHNICAL AREA
The present invention relates to a feeder pen or mechanical pencil used for drawing out drawing material.
PRIOR ART
Usually, a feed pen is known, described for example in the publication of Japanese unexamined patent application No. 2015-024081. This patent publication describes an application material extraction container which appropriately extracts a filled application material, by operation by a user. This application material extraction container comprises a filling element, a control cylinder, a movable body, and a screw cylinder. The filling element internally comprises a filling zone filled with the application material. The control cylinder is connected to a rear end part of the filling element so that it can rotate relative to the filling element. The relative rotation of the filling member and the actuator moves the movable body in an axial direction. The screw cylinder moves the movable body through this relative rotation.
With the application material extraction container described above, the screw cylinder includes a rear end tube. The control cylinder includes an internal tubular part inserted internally into the rear end tube. On an outer circumferential surface of the inner tubular portion, a protrusion located on a first side, which protrudes outward in a radial direction is provided. On an inner circumferential surface of the rear end tube, a protrusion located on the other side, which protrudes inward in the radial direction and which comes into contact with the protrusion on the first side in a direction of rotation is provided. The protrusion on the other side has elasticity in the radial direction through notches around it. In a state in which the inner tubular part has not yet been inserted inside the rear end tube, an inside diameter of one tip end of the other projection is smaller than an outside diameter of the outer circumferential surface of the end tube In a state in which the inner backward tubular part is inserted, always brought into the other projection is abutted against the outer circumferential surface of the rear end tube.

SUMMARY OF THE INVENTION TECHNICAL PROBLEM
Recently, different types of requests have increased regarding a feeding pen such as the application material extraction container described above. A feed pen which can be easily decomposed, and whose internal components can be easily replaced by a user, was desired. Namely, in the event of a failure of the internal component or a similar failure, a decomposed feed pen to guarantee easy replacement of this component by the user has been desired.
An object of the present invention is to provide a feed pen which can be easily broken down, and whose internal components can be easily replaced.
SOLUTION TO THE PROBLEM
To solve the problems described above, a feed pen according to the present invention comprises a tubular main body, a head tube, a middle tube and a ratchet mechanism. The head tube is a tube configured to be rotatably engaged with the main body. The middle tube has a tube portion configured to be inserted into a rear side portion of the head tube. The middle tube is positioned between the head tube and the main body, and is configured to be rotatably engaged with the head tube. The relative rotation between the head tube and the main body in a first direction moves a drawing material forward inside the head tube. The ratchet mechanism is configured to allow relative rotation between the head tube and the main body in a first direction. The ratchet mechanism is configured to regulate relative rotation in another direction opposite to the first direction. The ratchet mechanism includes an elastic protruding part and a concave-convex part, the elastic protruding part protrudes from an outer surface of the tube part, the elastic protruding part having elasticity in a radial direction, the part concave-convex being disposed on an inner surface of the head tube, the concaveconvex portion being configured to engage with the resilient portion projecting to be movable in an axial direction, and in rotation. A projection disposed at any one of the outer surface of the tube portion and the interior surface of the head tube is configured to removably engage with an annular convex portion disposed at the other in the direction axial.
This feed pen includes the ratchet mechanism which allows relative rotation between the head tube and the main body in the first direction, and regulates relative rotation in the other direction. The ratchet mechanism includes the resilient protruding portion, which protrudes from the exterior surface of the tube portion of the middle tube, and the concave-convex portion on the interior surface of the head tube. In this ratchet mechanism, the concave-convex part on the inner surface of the head tube is movable relative to the elastic part protruding from the outer surface of the tube part in the axial direction. The projection disposed at any one of the outer surface of the tube portion and the interior surface of the head tube removably engages the annular convex portion, which is disposed at the other, in the axial direction. Therefore, the head tube can be removably attached to the middle tube in the axial direction, thereby ensuring easy decomposition by removing the head tube from the middle tube. As a result, in the event of a failure of the internal component or in a similar case, the user can remove the head tube and easily replace the internal component.
The power pen can be configured as follows. The various drawing materials are stored in the head tube. The several sliding parts connected to the several drawing materials are respectively arranged. The plurality of sliding parts can slide relative to the main body by a predetermined amount. An arbitrary sliding part, among the several sliding parts, moves forward by a predetermined amount relative to the main body, so that the drawing material connected to the arbitrary sliding part is exposed from the head tube, and in this state, the head tube and the main body are rotated relatively in one direction, which allows the drawing material to move forward.
ADVANTAGEOUS EFFECTS OF THE INVENTION
According to the present invention, the feed pen can be easily broken down, and the internal component of the feed pen can be easily replaced.

DESCRIPTION OF EMBODIMENTS
The following describes embodiments of the present invention with reference to the drawings. In the following description, identical or corresponding elements are identified by identical symbols, and their description will not be repeated.
Figure 1 is a side view of a feed pen according to the embodiment. Figure 2 is a side view illustrating the feed pen of Figure 1 from which a cartridge is removed. Figure 3 is a vertical cross-sectional view illustrating the feeder pen of Figure 1. As shown in Figures 1 to 3, a feeder pen 100 according to the present embodiment is a multiple pen which sticks out (extract) so suitable any one of several drawing materials M1 to M4 filled inside four respective pipe elements IA to 1D by the operation of a user. In this embodiment, the drawing materials M1 to M4 are drawing materials having colors different from each other.
As drawing materials M1 to M4, for example, the following materials can be used: various cosmetic materials similar to a stick such as lipstick, lip gloss, eyeliner, lip pencil, eyebrow pencil, cheek blush, concealer, cosmetic stick, hair color, and Nail Art; or a core analogous to a stick of stationery material and the like. In addition, very soft stick-like materials (such as having a semi-solid form, a soft solid form, a soft form, a jelly form, a foam form and a paste form having these materials contained) may be used. A thin stick-like item with an outside diameter of 1 mm or less, a common stick-like item with an outside diameter of 1.5 to 3 mm, or a thick stick-like item with a outer diameter is 4mm or more can also be used.
The feed pen 100 includes a head tube 2 and a main body 3 as an external configuration. The head tube 2 internally comprises the pipe elements IA to 1D which load the drawing materials M1 to M4. The main body 3 is connected to a rear end part of the head tube 2, and engages with the head tube 2 so as to be able to rotate relatively. In the following description, an "axial line" means a central line of the feed pen 100 which extends from the front to the rear of the feed pen 100, and an "axial direction" means a direction along the line axial in the direction from front to back. It is assumed that the direction in which the drawing materials M1 to M4 are fed outward is a direction towards the front (direction of movement towards the front), and a direction opposite to the direction towards the front (a withdrawal direction) is a rearward direction.
Figure 4 is a vertical cross-sectional view illustrating a configuration of the tubular element IA and a peripheral area thereof. As shown in Figure 4, a movable body similar to a stick 5A having a thread or a male screw 5a is screwed into an interior of the tubular element IA. The movable body 5A is supported by a tubular support element 6A. The tubular element IA, the movable body 5A and the support element 6A can constitute a replaceable cartridge 10A of the main body 3. As a variant, a combination of the tubular element IA and the movable body 5A can constitute a replaceable cartridge. The pipe elements IB and IC have a configuration similar to the tubular element IA. It is also possible to form cartridges 10B and 10C using the hose elements IB and
IC, movable bodies 5B and 5C, and support members 6B and 6C, respectively. This also applies to the tubular element 1D.
The cartridge 10A comprises a sliding part 8A and a spring 9A (see FIG. 5) at the rear part. The sliding portion 8A is engaged with the support member 6A in the axial direction. The spring 9A pushes the sliding part 8A backwards. The cartridge 10A can be removably attached to the sliding part 8A in the axial direction. Similarly, the cartridges 10B and 10C include sliding portions 8B and 8C and a spring 9B and 9C at the rear portions, respectively. The first one
remaining cartridge component the tubular element 1D so understand similar one sliding part and a spring. Figure 5 and figure 6 are each a view in
perspective in cross-section and a vertical cross-sectional view of the feed pen 100. FIG. 7 is a perspective view in cross-section illustrating a forward movement of the first sliding part 8A. As shown in FIGS. 5 to 7, the head tube 2 and the main body 3 internally comprise the four pipe elements IA to 1D which load the drawing materials M1 to M4, the four mobile bodies, such as the mobile body 5A, the four support elements, like the support element 6A, the four springs, like the spring 9A, and the four sliding parts, like the sliding part 8A. These four pipe elements, four movable bodies, four support elements, four springs and four sliding parts have an identical configuration, except that drawing materials M1 to M4, different from each other, are loaded.
ίο
Consequently, what follows designates each of the four pipe elements, the four mobile bodies, the four support elements, the four springs and the four sliding parts in the form of a tubular element 1, of a mobile body 5, a support element 6, a spring 9, and a sliding part 8. The four cartridges, like the cartridge 10A, and the drawing materials M1 to M4 are indicated as cartridge 10 and drawing material M, respectively.
A middle tube 11 is engaged with a front end of the main body 3 so that it can rotate synchronously. The four support elements 6 are held inside the median tube 11. The median tube and the head tube 2 include a ratchet mechanism which allows relative rotation between the head tube 2 and the main body 3 (the tube median 11) only in a first direction. This ratchet mechanism 12 regulates the relative rotation between the head tube 2 and the main body 3 in another direction opposite to the first direction.
Figure 8 is a vertical cross-sectional view illustrating the head tube 2. As shown in Figure 8, the head tube 2 consists of an ABS resin (a synthetic resin for the copolymerization of acrylonitrile, butadiene and styrene). The head tube 2 has a tubular shape and an opening 2a to cause a front side part of the tubular element to appear on the front end. The head tube 2 includes therein a receiving area 2b for receiving the four cartridges 10. Any of the four pipe members 1, which are disposed within the receiving area 2b, is exposed from the opening 2a forward by the operation of a user.
On a front side of an outer circumferential surface of the head tube 2, an inclined surface 2c is arranged in an inclined manner so as to be tapered forward. An inner circumferential surface 2d on the front side of the head tube 2 is also tapered towards the front side. The inner circumferential surface 2d includes protrusions 2e which have circumferentially a large number of convex portions arranged side by side to engage the pipe elements 1 in a direction of rotation (a direction around the axial line). These convex parts extend in the direction of inclination of the inner circumferential surface 2d. These 2nd projections extend across the entire area from a first end to the other end in this direction of tilt. The circumferential intervals of these 2e projections decrease as they approach the front side.
At a rear side part of the inner circumferential surface of the head tube 2, a concave-convex part 2f, which is a part constituting the ratchet mechanism 12, is arranged. The concaveconvexe part 2f has circumferentially twenty-four parts of irregularities, which are arranged side by side and which extend in the axial direction over a predetermined length. At the rear of the concave-convex part 2f in the inner circumferential surface of the head tube 2, annular convex parts 2g, annular concave parts 2h and annular concave parts 2j are arranged. The annular convex parts 2g engage with the median tube 11 in the axial direction at the rear part of the head tube 2. The annular concave parts 2h are positioned on the front side of the annular convex parts 2g. The annular concave parts 2j are positioned on the rear side of the annular concave parts 2g.
Figure 9A is a side view illustrating the middle tube 11, and Figure 9B is a vertical cross-section view illustrating the middle tube 11. The middle tube 11 is an injection molded product made of POM (Polyacetal), and has a stepped cylindrical outer shape. The median tube 11 comprises a front tube 11a, a central tube 11b and a rear tube 11c in this order from the front to the rear. The central tube 11b has an outer shape having a larger diameter than that of the front tube 11a. The rear tube 11c has an outer shape with a smaller diameter than that of the front tube 11a and the central tube 11b.
The front tube 11a includes elastic projecting portions 11c, which constitute the other part of the ratchet mechanism 12, at two positions opposite to each other in an inner circumferential surface 11d. These elastic protruding portions lie engage with the concave-convex portion 2f on the head tube 2 in the direction of rotation, and are arranged protruding outward in a radial direction. At the peripheral areas of the elastic portions projecting from the front tube 11a, U-shaped bed notches for communicating between the inside and the outside of the middle tube 11 are formed. These bed notches provide radial elasticity to the elastic resilient protrusions. The elastic projecting parts 11e of the median tube 11 are always brought into abutment with the concave-convex part 2f on the head tube 2.
Figure 10 is a cross-sectional view taken along line AA of Figure 1. As shown in Figure 10, the concave-convex part 2f on the head tube 2, which is the first part constituting the mechanism ratchet 12, includes inclined surfaces 2fl and lateral surfaces 2f2. The inclined surfaces 2fl incline relative to the inner circumferential surface of the head tube 2. The side surfaces 2f2 are formed to be approximately perpendicular to the inner circumferential surface of the head tube 2. The elastic portions protruding 11 into the tube median 11, constituting the other part of the ratchet mechanism 12, comprise an inclined surface llel and a lateral surface lle2. The inclined surface llel inclines with respect to the outer circumferential surface of the middle tube 11.
The lateral surface lle2 is formed to be approximately perpendicular to a line tangent to the outer circumferential surface of the median tube 11.
As shown in FIGS. 9A and 9B, the notch reads in the median tube 11 comprises a pair of slots 11g and 11h, and a slot 11d. The slots 11g and 11h are pierced on both sides of the elastic protruding part 11 in the axial direction in the front tube 11a, and extend circumferentially. The slot 11j is pierced on a first side of the elastic protruding part 11 in the circumferential direction in the front tube 11a. Continuously with respect to the slots 11g and 11h, the slot 11j extends in the axial direction. A wall portion surrounded by the notches reads in the front tube 11a forms an arm 11k having flexibility in the radial direction. Therefore, the elastic protruding portion 11, which is disposed on an outer surface at a tip end of the arm 11k, has an elastic force (a pushing force) in the radial direction.
On an outer circumferential surface of the central tube 11b of the middle tube 11, protrusions 11m, an annular convex part of linen and a part of collar 11p are arranged. The projections 11m are removably engaged with the annular convex parts 2g of the head tube 2. The annular convex part linen enters the annular concave parts 2j of the head tube 2 from the rear. The collar part llp is positioned at the rear of the linear annular convex part. In the middle tube 11, a tube part positioned on the front side with respect to the collar part 11 is inserted into the head tube 2 from the rear.
On the rear tube 11c in the middle tube 11, protrusions 11q intended to engage the main body 3 in the direction of rotation are formed to extend in the axial direction. These protrusions 11q are formed at four positions arranged uniformly in the circumferential direction on an outer circumferential surface of the rear tube 11c. A convex part llr intended to come into engagement with the main body 3 in the axial direction is formed at the rear of the collar part llp. This convex part llr extends circumferentially between the projections llq.
An Il support member housing, which is a site for inserting the four sliding parts 8 through the axial direction, divides the middle tube 11 at the inner surface side of the collar part 11p. This support element housing They have circular openings for inserting the sliding parts 8 through the axial direction at four positions arranged uniformly in the circumferential direction.
In the middle tube 11, the front tube 11a and the central tube 11b are inserted towards the inside of the head tube 2 from the rear side. Then, the elastic protruding portions 11 in the front tube 11a engage with the concave-convex portion 2f of the head tube 2 in the direction of rotation. The projections 11m on the central tube 11b engage with the annular convex parts 2g of the head tube 2, and are adapted to the concave annular parts 2h. In addition, the linear annular convex part of the central tube 11b enters the annular concave parts 2j of the head tube 2.
Figure 11A is a vertical cross-sectional view illustrating the support member 6, and Figure 11B is an enlarged view of a front end of the support member 6 of Figure 11A. The support element 6 has a fully cylindrical shape. As the material of the support member 6, POM is used, for example. The support member 6 includes a hole 6a, a movable body pressure portion 6b, and a cylindrical shaped tubular portion 6c. The hole 6a is disposed on the front side of the support element 6, and receives the movable body 5. The movable body pressure portion 6b presses on the movable body 5. The tubular portion 6c extends rearward from the moving body pressure portion 6b.
The movable body pressure portion 6b of the support member 6 includes two slots 6d. The slots 6d extend from the front end to the rear side over a predetermined length so as to be mutually opposite at the level of the inner circumferential surface of the moving body pressing part 6b. With the movable body pressing portion 6b including the slots 6d, the elastic force of the resin of the support member 6 constricts the movable body 5 inward in the radial direction. These slots 6d allow the moving body pressure portion 6d to enlarge the diameter outward in the radial direction.
An extension portion 6g, which expands when viewed from the radial direction, is formed at a rear end of the slots 6d. This extension portion 6g appropriately adjusts the elastic clamping force of the movable body 5 from the movable body pressure portion 6b. Projections 6f are formed in a spiral pattern on an inner surface 6e of the movable body pressure portion 6b. The projections 6f are arranged in three positions on the inner surface 6e of the support element 6 along the axial direction. These projections 6f are brought into abutment with the male thread 5a of the movable body 5 from the outside in the radial direction. It is also possible to engage the movable body 5 in the axial direction, and to removably support the movable body 5 using the support member 6.
Four interior supports 6.
projections 6h are arranged at the level of the tubular part 6c of the element projections 6h are arranged at level with in the uniform manner in and extend in four positions arranged in circumferential direction, axial direction. These projections 6h are arranged in the form of a rotational stop for the movable body 5 with respect to the support element 6 comprising tapered surfaces at the front end. These tapered surfaces 6n cause the projections 6h to have a shape with the help of which the movable body 5 is easily inserted from the front side.
The projections 6h 6n tapered towards
These projections 6h form an internal space of the tubular part 6c of non-circular shape (a cruciform shape) in terms of cross-sectional shape when the tubular part 6c is cut at a plane perpendicular to the axial direction (see FIG. 10 ). The tubular part 6c further comprises through holes 6j having an elliptical shape extending in the axial direction, so as to pass through the interior and the exterior of the support element 6. The through holes 6j support core pins so as to prevent the core pins from being tilted by injection pressure during molding.
On an inner surface at the rear end of the support member 6, a projection 6m and an annular convex portion 6k are formed. The projection 6m engages with the sliding part 8 in the direction of rotation. The annular convex part 6k engages with the sliding part 8 in the axial direction. The 6m projection is arranged on a straight line, like the 6h projections described above.
Figure 12A is a perspective view illustrating the movable body 5, and Figure 12B is a side view illustrating the movable body 5. The movable body 5 has an external shape similar to a stick. As the material of the movable body 5, POM is used, for example. The movable body 5 comprises the male thread 5a and four extend in the axial direction, grooves on the circumference arranged in
5b, which exterior surface. The grooves 5b are four positions arranged uniformly in the circumferential direction,
The movable body 5 has a curved surface portion 5c where the male thread 5a is not formed on the surface at the rear side. This curved surface portion 5c is arranged to wrap around the movable body 5 when the movable body 5 reaches a limit of advance. The insertion of the male thread 5a, which is positioned at the rear of the curved surface part 5c, towards the rear of the projections 6f during the fixing of the support element 6 prevents the movable body 5 from falling from the support element 6. The movable body 5 fully forms the male thread 5a in the axial direction. "Shape fully in the axial direction" includes the case in which the male thread 5a is not partially formed, such as the case in which the curved surface portion 5c is formed in the middle of the movable body 5 in the axial direction, such as embodiment, in addition to the case in which the male thread 5a is formed on all the parts of the movable body 5 in the axial direction.
The four grooves 5b of the movable body 5 are arranged to bring the movable body 5 into the projections 6h of the support element 6 (see FIG. 10). These grooves 5b are arranged to rotate the movable body 5 synchronously with the support element 6. These grooves 5b form the cross-sectional shape when the male thread 5a and the grooves 5b are cut, at the plane perpendicular to the axial direction, in non-circular shape (the cruciform shape) corresponding to the internal space of the tubular part 6c of the support element 6.
A pitch of the male thread distance between the threads axial direction) is, by 1 mm or less, and is usual of the male thread is 6 mm or less. Consequently, a finer step shorter than the
has in the moving body 5 (a net male 5a in the example of 0.3 mm or more than preference 0.6 mm. The not typically 2 mm or more than e, the pitch of the male net 5a East
not common male nets.
The male thread 5a and the grooves 5b of the movable body 5 are inserted from the front into the support element 6 so as to provide a clearance between the grooves 5b and the projections 6h. The engagement of the projections 6f, which are arranged on the inner surface 6e of the support element 6, with the male thread 5a of the movable body 5 supports the movable body 5 via the support element 6. At this instant, the projections 6f push the male thread 5a from the outside in the radial direction, thereby increasing a support force of the movable body 5 by the support element 6.
An extraction part in the form of a column 5d is arranged on the front end of the movable body 5 for situated inside the Extraction part extracting the drawing material M the tubular element 1 forwards 5d comprises a lower surface 5e, which is positioned on the front end, a concave part 5f, which is made concave in transverse shape from the lower surface 5e, a lateral surface 5g, which extends circumferentially, and a tapered surface 5h, which tilts with respect to the lower surface 5e and is continuous with the lower surface 5e and the lateral surface 5g. The concave part 5f is a hole for inserting a tool intended to rotate the mobile body 5 during the fixing of the mobile body 5. The insertion of this tool in this concave part 5f allows the mobile body 5 to turn during the fixing and a similar work, lower surface 5e is a surface for extracting drawing material M towards the front.
The the
Figure 13A is a side view illustrating the tubular member 1, and Figure 13B is a vertical cross-section view illustrating the tubular member 1. The tubular member 1 has an approximately cylindrical shape. As the material of the tubular element 1, PP (polypropylene) is for example used. The coloring of the tubular element 1 with a color identical to the drawing material M or the configuration of the tubular element 1 made of transparent material guarantees easy identification of the color of the drawing material M. A female thread la is formed on the rear side of the inner circumferential surface of the tubular member 1 for moving the movable body 5 in the axial direction. As for the male thread 5a of the movable body 5, a female thread pitch la of the tubular element 1 (a distance between threads of the female thread la in the axial direction) is a fine pitch shorter than the pitch of female threads currents.
At the front of the female thread 1a in the inner surface of the tubular member 1, projections 1b extending in the axial direction are arranged in four positions arranged uniformly in the circumferential direction. These projections 1b guarantee that the drawing material M loaded in the tubular element 1 does not come out. Although the number of protrusions 1b is not particularly limited, the four protrusions 1b also effectively prevent the drawing material M from coming out. A concave groove 1c is disposed on the front side portion of the outer circumferential surface of the tubular member 1 to be engaged with the projections 2e of the head tube 2 in the direction of rotation. Several concave parts extending in the axial direction over a predetermined length are arranged circumferentially side by side on the concave groove le.
FIG. 14A is a side view illustrating the sliding part 8, and FIG. 14B is a perspective view illustrating the sliding part 8. As the material of the sliding part 8, an ABS resin is for example used. The color of the sliding part 8 is for example identical to the color of the corresponding drawing material M. Sliding the sliding part 8 having the desired color forward of a predetermined amount allows the drawing material M having the desired color to be exposed from the opening 2a of the head tube 2.
The sliding part 8 has a shape extending in the axial direction. On a front end of the sliding part 8, four claws 8a are arranged to be inserted into the tubular part 6c of the support element 6 from the rear side. The claws 8a are each arranged in four positions arranged uniformly in the circumferential direction. The claws 8a each have an elastic force in the radial direction, and are removably engaged with the annular convex part 6k of the support element 6. The claw 8a comprises an inclined part 8k, which is tapered towards the before, and a concave part 8m. The concave part 8m engages the annular convex part 6k in the axial direction at a rear end of the inclined part 8k. The supply of the inclined part 8k on this claw 8a forms the sliding part 8 in the form with which the sliding part 8 is easily inserted in the support element 6.
The sliding part 8 comprises a part similar to a stick in the shape of a circular stick 8c around which the spring 9 is wound on the front side. At a rear end of the stick-like part 8c, a flat surface 8d is disposed, projecting from the stick-like part 8c outward in the radial direction. The stick-like parts 8c are inserted through bed openings of the support member housing They of the middle tube 11 in the axial direction. A first end of the spring 9 is brought into abutment with the flat surface 8d. Thus, the sliding portion 8 includes the stick-like portion 8c, which is disposed on the front side, and the flat surface 8d, which projects outward in the radial direction at the rear end of the portion. analogous to a stick 8c, thus having a shape such that the spring 9 is easily fixed.
A rear protruding part 8e of the sliding part the other protruding sliding parts protruding part 8e is arranged on the side 8 to pull and bring back 8. This inward projection in the radial direction in the main body 3, and extends in the axial direction. On the rear end of the sliding part 8, a projecting part 8f, a rear end part 8g and a projecting part 8j are arranged. The protruding part 8f protrudes outward in the radial direction from the main body 3. The rear end part 8g protrudes rearward at the rear end of the sliding part 8, and is hooked to the main body 3. The projecting part 8j projects inwards in the radial direction of the main body 3, and has an inclined surface 8h. The protruding parts 8 of the other sliding parts 8 are brought into abutment with the inclined surface 8h.
The support member 6 is engaged with the front end of the sliding portion 8 configured as described above. At this time, engaging the claws 8a on the sliding portion 8 with the annular convex portion 6k of the support member 6 in the axial direction engages the support member 6 with the front end of the sliding portion 8 in the axial direction, thereby guaranteeing a removable support for the sliding part 8.
Figure 15A is a vertical cross-sectional view illustrating the main body 3, Figure 15B is a side view illustrating the main body 3, and Figure 15C is a cross-sectional view, taken along the line CC in Figure 15B. The main body 3 is an injection molded product made of ABS resin, and has a cylindrical shape with a closed bottom. Notched portions 3a extending in the axial direction to cause the projecting portion 8f of the sliding portion 8 to protrude outward are disposed on the rear side of the main body 3. The notched portions 3a are arranged in four positions arranged uniformly in the circumferential direction.
Flat parts 3b and protruding parts 3c are arranged at the notched parts 3a of the main body 3 inwards in the radial direction. The flat part 3d extends from the notched part 3a inwards in the radial direction. The protruding part 3c extends in the axial direction at the flat part 3b. The rear side of the protruding part 3c extends to a lower surface 3d of the main body 3. As shown in FIG. 6, a displacement of the protruding part 8f of the sliding part 8 forwards along notched portions 3a of the main body 3 moves the rear end portion 8g of the sliding portion 8 forward along the protruding portions 3c.
When the rear end part 8g reaches the front end of the protruding parts 3c, this rear end part 8g enters the notched parts 3a inward in the radial direction, and the rear end part 8g is attached to the front ends of the protruding parts 3c. While the rear end part 8g of a first sliding part 8 (for example, the sliding part 8A in FIG. 6) is hooked to the front ends of the protruding parts 3c, the protruding part 8e of the other part sliding 8 (for example the sliding part 8B in FIG. 6) comes into close contact with the inclined surface 8h of the first sliding part 8.
As illustrated in FIG. 15A, concave grooves 3e, an annular concave part 3f, and an annular concave part 3g are arranged on the front side of an inner circumferential surface of the main body 3. The concave grooves 3e come into engagement with the protrusions llq of the median tube 11 in the direction of rotation. The convex part llr of the median tube 11 engages the annular concave part 3f in the axial direction. The collar part 11p of the median tube 11 enters the annular concave part 3g from the front. The concave grooves 3e extend from the annular concave part 3g, which is positioned on the front end of the main body 3, towards the rear over a predetermined length. The concave grooves 3e are arranged in four positions arranged in a circumferential direction on the inner circumference of the body of the annular concave part 3f extends circumferentially between the concave grooves 3e.
uniform in the main surface 3. The
The four sliding parts 8 are inserted into the main body 3 from the front side. The protruding portions 8f of the sliding portions 8 protrude outward from the notched portions 3a. The median tube 11 enters the front end of the main body 3. When the median tube 11 enters the main body 3, the projections llq of the median tube 11 enter the concave grooves 3e of the main body 3. The convex part llr of the median tube 11 engages the annular concave part 3f of the main body 3 in the axial direction. Next, the collar portion 11p of the middle tube 11 enters the annular concave portion 3g, and thus the middle tube 11 is engaged with the main body 3 so that it can rotate synchronously.
As illustrated in FIG. 5 and FIG. 7, the spring 9 (the springs 9A to 9C) is wound around the stick-like part 8c so as to provide the play with respect to the outer periphery of the stick-like part stick 8c of the sliding part 8. A first end (the front end) of the spring 9 is brought into abutment with the rear wall of the support element housing They at the level of the median tube 11. At the same time, the the other end (the rear end) is brought into abutment with the flat surface 8d, which is positioned close to the center of the sliding part 8 in the axial direction. This spring 9 pushes the sliding part 8 backwards.
The following describes operations of the feed pen 100 configured as described above, for use. The feeder pen 100, in an initial state shown in FIG. 5, positions the four sliding parts 8 at the rear end of the notched parts 3a of the main body 3, and positions the four pipe elements 1 inside the head tube 2. As shown in FIG. 6 and FIG. 7, in this state, a displacement of the sliding part 8A forwards along the notched parts 3a by a predetermined amount moves the cartridge 10A, which is put engaged with the sliding part 8A in the axial direction, towards the front, and the drawing material M1 is exposed towards the front from the opening 2a of the head tube 2.
At this instant, the entry of the front side part of the tubular element IA into the inner circumferential surface 2d of the head tube 2 deforms the stick-like part 8c of the sliding part 8A so as to curve it relative to in the axial direction, and the concave groove 1c of the tubular element IA engages with the projections 2e of the head tube 2 in the direction of rotation. Then, the rear end part 8g of the sliding part 8A enters inwards in the radial direction at the level of the front end of the protruding parts 3c of the main body 3.
In this state, for example, when the user relatively rotates the main body 3 in a first direction (for example clockwise) relative to the head tube 2, the median tube 11, the four sliding parts 8, the four support elements 6 and the four movable bodies 5 begin to rotate in the first direction. The pipe elements IB to 1D where the concave grooves are not engaged with the protrusions 2e of the driving tube 2 rotate in association with the relative rotation in the first direction.
Furthermore, the support element 6A connected to the tubular element 1 where the concave groove le is engaged with the projections 2e of the head tube 2 via the movable body 5A begins to rotate in the first direction in association with the relative rotation in the first direction. The tubular element IA where the concave groove is engaged with the projections 2e of the driving tube 2 does not rotate at the same time as the rotation of the movable body 5A in the first direction, and the movable body 5A rotates so relative to the tubular element IA. Consequently, the relative rotation in the first direction acts as a screwing action between the male thread 5a of the movable body 5 and the female thread la of the tubular element 1, and the movable body 5A begins to move forward. relative to the tubular element IA. When the lower surface 5e of the extraction part 5d of the movable body 5A extracts the drawing material Ml, which is loaded in the tubular element IA, towards the front, the movable body 5A and the drawing material Ml begin to move together forward relative to the tubular element IA.
As illustrated in FIG. 10, at the level of the relative rotation in the first direction, the elastic projecting parts lie, which constitute the ratchet mechanism 12, of the median tube 11 come into engagement with the concave-convex part 2f of the tube head 2 in the direction of rotation, and the elastic force via the notches llf radially pushes the elastic projecting parts. This repeats the engagement and release (the engagement and the release of the engagement) between the elastic protruding portions 11e and the concave-convex portion 2f. That is, the realization of the relative rotation in the first direction with the elastic projecting parts lie and the concave-convex part 2f engaged in the direction of rotation brings inclined surfaces llel of the elastic projecting parts linked in stop with the inclined surfaces 2fl of the concave-convex part 2f. In this state, the inclined surfaces llel slide so as to move upwards above the inclined surfaces 2fl.
After the elastic resilient protruding parts have passed the convex parts of the concaveconvex part 2f, the elastic resilient protruding parts engage with the concave-convex part 2f again in the direction of rotation. Accordingly, each time the elastic projecting portions lie and the concave-convex portion 2f engage with each other and are released therefrom, a rattling sensation is provided to the user. The concave-convex part 2f has twenty-four irregularities arranged side by side in the circumferential direction; therefore, whenever the relative rotation is made in the first direction by 15 °, the rattling sensation is provided to the user.
At the same time, when a user attempts to relatively rotate the main body 3 in the other direction (for example, counterclockwise), which is a direction opposite to the first direction relative to the head tube 2, the lateral surfaces lle2 of the elastic projecting parts lie, which constitute the ratchet mechanism 12, are brought into abutment with the lateral surfaces 2f2 of the concave-convex part 2f, thereby regulating the rotation relative in the other direction. Consequently, the head tube 2 and the main body 3 do not rotate relatively in the other direction. That is, a rotational force (a couple) in the relative rotation in the first direction is set to be a force ensuring easy rotation, while a rotational force in the relative direction in the another direction is established to be a force through which rotation is not easily effected. For example, with the outside diameter of the main body 3 designed around 14 mm, the torque of the relative rotation in the first direction is established to be 0.1 N »m (Newton meter) or less, and the torque of the relative rotation in the other direction is set to be 0.2 N »m or more.
As illustrated in FIG. 6, in the state in which the forward movement of the sliding part 8A displaces the tubular element IA forwards, and the drawing material M1 is exposed forwards, move the the other sliding part 8B forward of the predetermined amount brings the projecting part 8e of the sliding part 8B close to the inclined surface 8h of the sliding part 8A in abutment with the inclined surface 8h of the sliding part 8A. The stop of the protruding part 8e of the sliding part 8B with the inclined surface 8h of the sliding part 8A extracts the sliding part 8A outwards in a radial direction, thereby freeing the rear end part 8g from the part sliding 8A from the front end of the projecting parts 3c. The pushing force by the rear spring 9A pushes and brings back the sliding part 8A towards the rear end position of the notched parts 3a.
As described above, this feeder pen 10 includes the ratchet mechanism 12 which allows the relative rotation between the head tube 2 and the main body 3 in the first direction, and regulates the relative rotation in the other direction. The ratchet mechanism 12 comprises the elastic protruding parts 11e, which protrude from the outer surface of the front tube 11a (the tube part) of the middle tube 11, and the concaveconvex part 2f on the internal surface of the head tube 2. In this ratchet mechanism 12, the concave-convex part 2f of the interior surface of the head tube 2 is movable relative to the elastic protruding portions 11e of the exterior surface of the front tube 11a in the axial direction.
The projections 11m disposed on the outer surface of the central tube 11b (the tube portion) of the middle tube 11 are removably engaged with the annular convex portions 2g, which are disposed on the inner surface of the head tube 2, in the axial direction. Thus, the median tube 11 has a double function of ratchet mechanism 12 by the elastic projecting parts binds and being able to be removably fixed by the projections 11m with the first component. Therefore, the head tube 2 can be removably attached to the middle tube 11 in the axial direction, thereby ensuring easy decomposition by removal of the head tube 2 from the middle tube 11. Consequently, in the case of 'a failure of the component such as the internal cartridge 2, the user can remove the head tube 2 and easily replace the internal component.
Using the feeder pen 100, the pi drawing materials M are stored in the tube of The head tube 2 comprises the several sliding elements 8 connected to the various materials of respective M, and can slide relative to the head users 2. main body drawing parts 3 of the predetermined quantity. Among the several sliding parts 8, the forward movement of any given sliding part 8 relative to the main body 3 by the predetermined amount moves any given drawing material M forwards. As a result, the multiple design materials M can be stored in the feed pen 100 and any given design material M can be moved forward for use.
That is to say that the feed pen 100 comprises the several pipe elements 1, movable bodies 5 and support elements 6. The feed pen 100 comprises the several sliding parts 8 connected to the respective respective support elements 6, and can slide relative to the main body 3 by the predetermined amount. Among the several sliding parts 8, the forward movement of any given sliding part 8 relative to the main body 3 by the predetermined amount exposes any given drawing material M from the head tube 2. In this state, relative rotation of the head tube 2 and the main body 3 in the first direction moves the drawing material M forward. This allows the feed pen 10 to internally receive the multiple design materials M. Even if the multiple design materials M are received, this also ensures that the feed pen is kept at a small diameter.
The feeding pen 100 loads the drawing materials M towards the inside of the pipe elements 1, and receives the mobile bodies 5 inside the pipe elements 1 and the support elements 6. The mobile body 5 forms entirely the male thread 5a in the axial direction. This guarantees screwing and support of the male thread 5a in any given position by the tubular element 1 and the support element 6. The male thread 5a of this movable body 5 is screwed into the female thread 1a of the interior surface. of the tubular element 1, and is brought into abutment with the projections 6f, which are arranged at the rear of the tubular element 1, on the inner surface 6e of the support element 6 from the outside.
Consequently, as shown in FIG. 16A and FIG. 16B, which are views in vertical cross section of the tubular element 1, of the movable body 5 and of the support element 6, the tubular element 1 screwed with the movable body 5 and the support element 6 supporting the movable body 5 can be arranged in the axial direction, thereby limiting a radial enlargement of the feed pen 100. Consequently, this feed pen 100 makes it possible to obtain a feed pen 100 of small diameter.
Using the feeder pen 100, for example, the internal diameter of the thread of the female thread 1a of the tubular element 1 is slightly larger than the internal diameter of the projection 6f of the support element 6. Eu with regard to this, although a clearance is formed between the male thread 5a of the movable body 5 and the thread of the female thread la, a clearance is not formed between the male thread 5a and the projections 6f, thereby ensuring to always bring the projections 6f into abutment with the male thread 5a.
The protrusions 6f of the support member 6 are formed in a spiral pattern on the inner surface 6e of the support member 6. This allows the protrusions 6f to be engaged with the male thread 5a along the form of
male net 5a, in guaranteeing so a increase of the strength ofsupport 6. support net male 5a by element of The element of support 6 understands the slots 6d, stretching in The direction axial from the game
end, on the front side. The provision of these slots 6d guarantees the increase of the radial elastic force at the end portion of the front side of the support element 6. This guarantees the increase of the radial support force by the element of support 6, thereby guaranteeing an even more reliable limitation of the outlet of the movable body 5 from the support element 6.
Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and variants can be made without departing from the scope of the invention, or applications to other elements can be implemented. That is to say that the configuration of the respective components constituting the pen feeder 100 can be modified appropriately without departing from the scope of the invention.
For example, as shown in FIGS. 8 to 9B, the embodiment described above describes the example in which the elastic projecting parts binds from the middle tube 11 and the concave-convex part 2f of the head tube 2 constitute the ratchet mechanism 12, and the projections 11m, which are arranged on the outer surface of the middle tube 11, and the annular convex portions 2g, which are arranged on the inner surface of the head tube 2, are removably engaged in the axial direction. However, as a feeding pen according to a modification, annular convex parts detachably engaging with the elastic resilient protruding parts, which constitute the ratchet mechanism 12, in the axial direction, can be arranged on the inner surface of the head tube 2.
That is, the feed pen according to this modification comprises the tubular main body 3, the head tube 2 and the median tube 11. The head tube 2 is engaged with the main body 3 in order to be able to rotate by relative way. The middle tube 11 has the tube parts (the front tube 11a and the central tube 11b) inserted inside the rear side of the head tube 2. The middle tube 11 is positioned between the head tube 2 and the main body 3. The middle tube 11 is engaged with the head tube 2 to be able to rotate relatively. The relative rotation between the head tube 2 and the main body 3 in the first direction moves the drawing material M forwards inside the head tube 2. The ratchet mechanism 12 allows the relative rotation between the tube head 2 and main body 3 in the first direction. The ratchet mechanism 12 regulates the relative rotation in the other direction opposite to the first direction. The ratchet mechanism 12 comprises the elastic projecting parts 11e and the concave-convex part 2f. The elastic projecting portions lie projecting from the outer surface of the tube portion of the middle tube 11, and have elasticity in the radial direction. The concave-convex part 2f is arranged on the inner surface of the head tube 2. The concave-convex part 2f engages with the elastic projecting parts linked to be movable in the axial direction, and to be rotary. The elastic protruding portions lie removably engaged with the annular convex portion disposed at the inner surface of the head tube 2 in the axial direction.
As described above, using the feed pen according to this modification, the elastic projecting parts 11 are detachably engaged with the annular convex part disposed on the inner surface of the head tube 2 in the axial direction. As a result, the elastic resilient protrusions, which constitute the ratchet mechanism 12, removably engage the annular convex portions of the inner surface of the head tube 2. Thus, the resilient elastic protrusions also have the function of being able to be detachably fixed. Thus, the elastic projecting parts lie can have the function of being able to be fixed in a removable manner. This eliminates the 11m projections.
The embodiment described above describes the example in which the annular convex parts 2g, the annular concave parts 2h, which are positioned on the front side of the annular convex parts 2g, and the annular concave parts 2j, which are positioned on the rear side of the annular convex parts 2g, are arranged on the inner surface of the head tube 2. However, the annular concave parts 2h or the annular concave parts 2g can be omitted. That is, at least any one of the front side of the annular convex portions 2g and the rear side of the annular convex portions 2g can be formed on a flat surface.
The embodiment described above describes the example in which the projections 11m, which are arranged on the outside surface of the middle tube 11, and the annular convex parts 2g, which are arranged on the inside surface of the head tube 2, removably engage with each other in the axial direction. However, aspects of the shape and arrangement of the projections 11m of the middle tube 11 and the annular convex parts 2g of the head tube 2 are not limited to the example described above. Furthermore, instead of the protrusions 11m and the annular convex parts 2g, an annular convex part can be formed on the outer surface of the middle tube 11, and a protrusion can be formed on the inner surface of the head tube 2. This convex part annular on the outer surface of the middle tube 11 can be removably engaged with the projection on the inner surface of the head tube 2 in the axial direction. The embodiment described above describes the example in which the median tube 11 comprises the front tube 11a and the central tube 11b, but however appropriately changing the shape of the median tube is also possible.
As illustrated in FIGS. 11A and 11B, the embodiment described above describes the example where the provision of the slots 6d to the support element 6 increases the radial elastic force at the front end of the support element 6. This support member 6 may further include an elastic portion which provides an elastic force external to the movable body 5, which is internally supported by the support member 6. Specifically, for example, an annular concave portion extending circumferentially can be formed between the several slots 6d of the external surface of the support element 6, and an O-ring, which is an elastic body, can be introduced into this annular concave part. In this case, the introduction of the O-ring in the annular concave part clamps the movable body 5 supported by the support element 6 inwards in the radial direction, thus still reliably preventing the movable body 5 from coming out of the support member 6. That is, the elastic force outward in the radial direction via the elastic part ensures a further increase in the support force by the support member 6
The embodiment described above describes the example where the projections 6f on the support member 6 are formed in the spiral pattern on the inner surface 6e of the support member 6. However, aspects of the shape and the arrangement of the projections formed on the inner surface 6e of the support member 6 are not limited to the example described above. For example, protrusions in a pattern other than the spiral pattern can be arranged in several positions along the axial direction on the inner surface 6e of the support member 6. In this case also, the several protrusions arranged along from the axial direction each press the male thread 5a of the movable body 5 outward in the radial direction. This ensures that the male thread 5a is less likely to come out of the support element 6. Thus, the several projections arranged along the axial direction can increase the resistance against the exit of the male thread 5a.
In addition, the embodiment described above describes the example where the projections 6f of the support element 6 are arranged at the three positions along the axial direction on the inner surface 6e of the support element 6. However, the projection (s) 6f may be arranged in one position, two positions or four or more positions along the axial direction.
As illustrated in FIG. 13B, the embodiment above describes the example where the projections 1b are arranged in four positions arranged uniformly in the circumferential direction on the front of the female thread 1a in the internal surface of the element of tube 1. These projections lb prevent the drawing material M loaded towards the tubular element 1, from coming out. However, measures to prevent the drawing material M from coming out can be taken with elements other than the projections 1b. For example, in place of the projections 1b, measures to increase a coefficient of friction can be taken on the inner surface of the tubular element 1. Alternatively, measures to prevent the exit can be taken by forming the inner surface of the tubular element 1 in a non-circular shape, such as a polygonal shape.
The embodiment described above describes the feed pen 100, a multiple pen, which comprises the drawing materials M1 to M4 having colors different from each other. However, the feed pen may include drawing materials having thicknesses different from each other. In addition, the feed pen can include several drawing materials whose materials or applications are different from each other. The number of drawing materials is not limited to four, but can be two, three, five or more.
Furthermore, the feed pen according to the present invention may not be a multiple pen. That is to say that the feed pen according to the present invention can each comprise one of the drawing material, the tube element, the movable body and the support element.
