  However, in the configuration of Patent Document 1, the internal structure of the pen is complicated, and in the configuration of Patent Document 2, a bulky jig other than the pen is required, leading to an increase in cost. Although the jig of Patent Document 3 has a simple structure, there is a disadvantage in that it also increases the cost and bulk because a metal must be used for the material so that the pen tip can be securely picked by a pair of clamping parts. . Such bulkiness also leads to inconvenience in storage and distribution.

  An object of the present invention is to realize a shaft-shaped member removal tool and a shaft-shaped member set that effectively solve these problems.

  In order to achieve this object, the present invention takes the following measures.

That is, the shaft-shaped member removal tool according to the present invention is integrally provided with a shaft portion and a head portion having a diameter larger than the tip portion at a position continuous to the tip portion of the shaft portion. And a shaft-like member that is attached to the attachment object with its head exposed, and for removing the shaft-like member from the attachment object, the head of the shaft-like member can pass through The first opening and the second opening formed of a round hole through which the tip of the shaft portion of the shaft-shaped member can pass and the head cannot pass are formed in a sheet-like base material, and the circle forming the second opening The openings are formed in a state where the openings are in communication with each other so that the opening edge of the hole is substantially C-shaped, and the tip of the shaft portion of the shaft -shaped member is moved to the first by moving the substrate relative to the shaft -shaped member. through an opening positioned at a site its outer periphery is engaged along the inner periphery of the second opening, the axial part of the substrate in this state It allows characterized by being adapted to be added to the force to pull out the opening edge of the second opening is hooked from the periphery of the shank to the head to the shaft-like member from the attachment object pulling.

  In this way, as long as the opening edge of the second opening is hooked on the head and pulled, the head is compressed in the reduced diameter direction without causing liquid scattering or the like, and the substrate is The possibility of detachment is reduced, and the shaft-like member can be pulled out reliably. Moreover, since the force at the time of pulling out the shaft-like member can be received with the strength of the base material through the opening edge of the base material, it is not necessary to use a metal jig etc. with sufficient durability even with a resin sheet or the like. And since a base material is a sheet form, it also becomes easy to handle in a state which is not bulky.

  In order to simply use the sheet-like base material, a knob for pulling a part of the base material in the axial direction is the same as the first opening and the second opening in the base material. It is desirable to set it to the surface.

The shaft portion and a head portion having a diameter larger than that of the tip portion are integrated with the shaft portion, and the head portion and the head portion of the shaft portion are exposed to be attached to the attachment object. In a removal tool for pulling out the shaft-shaped member from the attachment object, the first opening through which the head of the shaft-shaped member can pass and the tip of the shaft portion of the shaft-shaped member And a second opening through which the head cannot pass is formed in a state where the openings are in communication with each other in a sheet-like base material, and the base member is moved relative to the shaft-like member to thereby move the base member. By positioning the tip of the shaft portion inside the second opening through the first opening and pulling a part of the base material in the axial direction in this state, the opening edge of the second opening is hooked on the head. In constructing the shaft-shaped member such that a force in the direction of pulling out from the attachment object can be applied. The present invention in order to facilitate withdrawal picking substrate, the substrate includes a pair of bent pieces which are bent chevron and a bottom piece bent further in the direction of polymerizing with each other from the front end of these bent pieces, the group knob for pulling the portion of the timber in the axial direction is set to the pair of bent pieces, the first opening and the second opening, characterized in that it is formed respectively on the bottom piece.

  As a suitable application example of the present invention, there is a case where the shaft-shaped member is a pen tip and the attachment object is a writing instrument body provided with a cylindrical portion into which the pen tip is inserted.

  In order to configure the removal tool efficiently without waste and to be able to handle it with the shaft-shaped member, the removal tool constitutes a mount to be accommodated in the bag body, or the removal tool is cut from the mount to be accommodated in the bag body. It is desirable that the shaft-shaped member and the mount are accommodated in the bag body in a state where the shaft-shaped member is backed up on the mount and the shaft-shaped member set is formed.

  Alternatively, it is also preferable to form a hollow case with the removal tool, or to form the removal tool at a position where it can be cut off from the hollow case, and to accommodate the shaft-shaped member in this case to form a shaft-shaped member set. is there.

  Since the present invention has the configuration described above, it is possible to configure a detaching tool for pulling out a shaft-shaped member such as a pen tip or a thumbtack with a very simple configuration with little cost, and the bulkiness is also effective. Therefore, it can be used as a new and useful tool for removing a shaft-shaped member and a shaft-shaped member set which can be eliminated and the convenience of storage and distribution is improved.

Hereinafter, some embodiments of the present invention will be described with reference to the drawings.
(First embodiment)

  The removal tool 1 of this embodiment shown in FIG. 1A is used for pulling out a pen tip 2 that is a shaft-like member from a pen body 3 that is an attachment object. The nib 2 is made of felt or the like, and the nib 2 and the pen body 3 constitute a writing instrument such as an oily or aqueous marker.

  The nib 2 is integrally provided with a shaft portion 21 and a head 22 having a diameter larger than that of the tip 21a at a position continuous to the tip 21a of the shaft portion 21, and the tip 21a of the shaft portion 21. The shaft portion 21 is fitted into the cylindrical portion of the pen body 2 with the head portion 22 exposed. The diameter of the shaft portion 21 is increased again on the proximal end 21b side than the distal end 21a, and the distal end 21a constitutes a constricted portion between the head portion 22 and the proximal end 21b. Hereinafter, the tip 21a is also referred to as a constricted portion 21a as necessary.

And the removal tool 1 of this embodiment consists of the structure which used the comparatively hard resin sheet (for example, PET of thickness about 0.8 mm) as the base material 1a, and opened the polishing hole 11 in this base material 1a. . The polishing hole 11 is formed by partially polymerizing a relatively large-diameter round hole 12 and a small-diameter round hole 13 so that the opening edge of the small-diameter round hole 13 is substantially C-shaped . The large-diameter round hole 12 is the first opening of the present invention through which the head 22 of the nib 2 can pass, and the small-diameter round hole 13 allows the constricted portion 21a to pass through and the head of the nib 2 Reference numeral 22 denotes a second opening of the present invention that cannot pass through.

  In the case of the pen tip 2 to which this embodiment is applied, the width w of the constricted portion is set to about 0.8 to 1 mm, the depth d is set to about 0.5 mm, and the diameter m of the head 22 is set to about 5 to 6 mm. Has been.

Then, as indicated by an arrow in FIG. 1A, the head portion 22 of the pen tip 2 is inserted into the first opening 12 to position the constricted portion 21a at the opening edge. by relatively moving the timber 1, 1 a constricted portion 21a of the pen tip 2 as shown in (b) with the first opening 12 is moved to the inside of the second opening 12 of the tip end of the shaft portion 21 The constricted portion 21a is positioned at a portion that engages along the inner periphery of the second opening 12 made of a round hole, and the knob portion 14 set as a part of the base material 1 in that state is in the axial direction indicated by an arrow in the figure. By pulling, the opening edge of the second opening 13 is hooked from the periphery of the shaft portion 21 to the head portion 22 so that a force in the direction of pulling out the pen body 2 from the pen body 3 can be applied.

  The knob 14 in this case is set to a peripheral edge on the same surface as the first opening 12 and the second opening 13 in the base material 1a, specifically, two opposing sides. By pulling 14 and operating in the axial direction, a drawing force along the axial direction can be applied to the pen tip 2 through the base 1a.

  In this way, if the pen tip 2 has the shaft portion 21 and the head portion 22, as long as the opening edge of the second opening 13 is hooked on the head portion 22 and pulled, the head portion 22 is used as in the case of using pliers. The base 1 can be pulled out from the pen body reliably without reducing the possibility that the base material 1 is detached from the pen tip 2 even when it is pulled out. it can. Moreover, since the force for pulling out the pen tip 2 can be received by the member strength of the base material 1 through the opening edge of the base material 1a, a metal jig or the like is used with sufficient durability even with a resin sheet or the like. In addition, since the substrate 1a is in the form of a sheet, it can be easily handled without being bulky.

  In particular, the knob 14 for pulling a part of the base material 1a in the axial direction is set on the same surface as the first opening 12 and the second opening 13 in the base material 1, and is in the form of a sheet. Since the base material 1 can be used by simply hooking and pulling it immediately in the form of a sheet, it is easy to use, and the bulk of the base material 1a when not in use is only the thickness, and the handling convenience is extremely It will be good. Furthermore, since the pair of opposite sides is used as a knob 14 and can be picked with the thumb and forefinger and pulled in the axial direction as much as possible, the pulling force can be applied to the pen tip 2 as straight as possible, and the pen can be efficiently used. The tip 2 can be pulled out.

When the resin sheet is made of a softer or thinner material, the base material 101a of the removal tool 101 is composed of a pair of bent pieces 110a and 110b as shown in FIG. Polishing holes 111a and 111b similar to the above may be formed in 110a and 110b, and the polishing holes 111a and 111b may be superposed in the thickness direction by folding in half. In addition to setting the knobs on the two opposite sides as described above, it is also effective to set the knob 114 on the edge opposite to the fold line so that the bent pieces 110a and 110b are bound together. is there.
(Second Embodiment)

  The removal tool 201 of this embodiment shown in FIG. 3 and FIG. 4A is also used to pull out the pen tip 2 that is a shaft-like member and has the same configuration as that of the above-described embodiment from the pen body 3 that is an attachment object. Is done.

  The removal tool 201 of the present embodiment uses a relatively thin and soft resin sheet (for example, PET having a thickness of about 0.3 mm) as a base material 201a, and the base material 201a is a pair of bent pieces 210a that are bent into chevron shapes, 210b, and bottom pieces 210c and 210d that are bent in a direction that overlaps with each other from the ends of the bent pieces 210a and 210b. A part of the base material 201a is axially arranged as indicated by an arrow A in FIG. For pulling, a knob 214 is set near the folding line of the pair of bent pieces 210a and 210b, and polishing holes 211a and 211b are formed in the bottom pieces 210c and 210d, respectively. These polishing holes 211a and 211b are obtained by partially superposing and communicating a relatively large-diameter round hole 212a and a small-diameter round hole 213a (212b and 213b). The large-diameter round holes 212a and 213a The first opening of the present invention through which the head portion 22 of the nib 2 can pass is formed, and the small-diameter round holes 213a and 213b can pass through the constricted portion 21a and the head portion 22 of the nib 2 cannot pass through. It is the same as that of the said embodiment by the point made into 2nd opening. The polishing holes 211a and 211b move in a direction in which the bent pieces 210a and 210b approach or move away from each other, and along with this, the first and second openings 212a and 212a move along the direction in which the bottom pieces 210c and 210d move relative to each other. 213a (212b, 213b) are adjacent to each other, and the first openings 212a, 212b are overlapped with each other as shown in FIG. 4B, and the second openings 213a, as shown in FIG. It is comprised so that 213b can take the state which superposes | polymerizes.

  In this embodiment, a tongue-like operation piece 215 protrudes from one bottom piece 210c and is pulled out through a slit 216 provided at a cut and raised position at a boundary portion between the other bottom piece 210d and the bent piece 210b. When the operation piece 215 is operated as shown by an arrow B in FIG. 4A, the first openings 212a and 212b are superposed with each other as shown in FIG. The relative positions of the bottom pieces 210c and 210d are switched to a state where the second openings 213a and 213b are superposed as shown in c).

  Thus, by inserting the head portion 22 of the pen tip 2 into the first openings 212b and 212a up to the constricted portion 21a in a state where the first openings 213a and 213b are overlapped, and operating the operation piece 215 from this position. The bottom pieces 210c and 210d of the base material 201a are moved relative to the pen tip 2, and the constricted portion 21a is positioned inside the portion where the second openings 213b and 213a overlap each other. Then, in this state, by pulling the knob 214 of the base material 201a in the axial direction indicated by the arrow A in FIG. 4A, the opening edges of the second openings 213a and 213b are hooked on the head 22, and the pen tip 2 can be applied with a force in the direction of pulling out from the pen body 3. What is indicated by reference numeral 217 in FIG. 3 is a slit for easily deforming the bent pieces 210a and 21b to make it easier to pick the knob 214.

  Even in this case, as long as the pen tip 2 has the shaft portion 21 and the head portion 22 and the opening edges of the second openings 213a and 213b are hooked on the head portion 22 and pulled, the head portion 22 is reduced in the diameter reducing direction. Therefore, the pen tip 2 can be reliably pulled out from the pen body 3 without reducing the possibility of the base material 201a coming off when being pulled out. Moreover, since the force for pulling out the nib 2 is received by the strength of the member in the surface direction of the base material 201a through the opening edge of the base material 201a, a metal jig that is sufficiently durable with a resin sheet or the like in this case as well. In addition, since the base material 201a has a sheet shape when it is unfolded, it can be easily handled without being bulky.

  In particular, in this embodiment, the operating force when picking and pulling the knob portion 214 acts equally on the pen tip 2 from the pair of bottom pieces 210c and 210d. Therefore, as shown in FIG. Thus, a pulling force can be applied, and the pen tip can be pulled out straight and efficiently.

In addition, the polishing holes 211a and 211b provided in the pair of bottom pieces 210a and 210b in FIG. 4 have a direction in which the bent pieces 210a and 210b move in a direction toward or away from each other as in the removal tool 201 ′ illustrated in FIG. The first openings 212a and 212b and the second openings 213a and 213b may be adjacently opened in the orthogonal direction. In this case, the pen tip 2 is inserted into the first openings 212a and 212b in a state where the first openings 212a and 212b and the second openings 213a and 213b are superposed from the beginning, and then the substrate By moving the pen tip 2 to the second openings 213a and 213b side by moving the 201a relative to each other, the pen tip 2 can be pulled out in the axial direction as in the above embodiment.
(Third embodiment)

  The removal tool 301 of this embodiment shown in FIG. 6 is also used for pulling out the pen tip 2 that is a shaft-like member and has the same configuration as that of the above-described embodiment from the pen body 3 that is an attachment object.

  The removal tool 301 of the present embodiment also uses a relatively soft resin sheet (for example, PET having a thickness of about 0.3 mm) as a base material 301a, and has a hole 311 in a form in which the upper bases of the trapezoid face each other. The first opening 312 that allows the head 22 of the pen nib 2 to pass through is formed in a portion close to the lower bottom of both sides, and the periphery of the portion (stenosis) where the upper bases of the center overlap each other is the pen tip The second constricted portion 21a is a second opening 313 through which the head portion 22 cannot pass.

  Then, the pen nib 2 is inserted into one of the pair of first openings 312 and 312 provided in the base member 301a as indicated by an imaginary line in FIG. 6B, and then the constricted portion 21a is inserted into the second portion 21a. The bent portion 310a, 310b on both sides is folded into a valley fold with the portion where the constriction portion is provided as a fold line, and the knob portion 314 set at a part thereof is pinched in the axial direction. By pulling, the opening edge of the second opening 313 is hooked on the head 22 so that a force in the direction of pulling out the pen body 2 from the pen body 3 can be applied.

In this way, the pen tip 2 can be pulled out even if the base material 301a is thin, and a pulling force can be applied to the pen tip 2 along the axial direction as much as possible, thereby simplifying the structure.
