◎ Outline of Embodiment Generally, as shown in FIG. 1A, for jewelry such as pierced earrings and neckties, a pinned decorative body 10 and a pin 11 of the pinned decorative body 10 are detachably attached. It also includes a pin fastener 1 for fastening the pinning ornament 10 having the pin 11 inserted in the pin hole of the mounted portion to the mounted portion. The pinned decorative body 10 here means a decorative body to be pinned, and includes not only a decorative body with a pin but also a pinned decorative body. Further, the pin 11 is not limited to a pin 11 having a curved tip shape, but also includes a pin 11 having a sharp needle shape.
The pin fastener 1 shown in FIG. 1 (a) is a schematic representation of an outline of an embodiment to which the present invention is applied, and is a state before the pin 11 of the pinned decorative body 10 is attached. Is shown.
In this example, the pin fastener 1 has a pin insertion hole 2a on the side where the pin 11 is inserted, and an inner housing 2 having a hollow portion 2b leading to the pin insertion hole 2a, and the pin 11 are inserted. It has a bottomed cavity 3a that opens to the side, and the inner housing 2 is slidably housed in the cavity 3a in contact with the bottom of the cavity 3a to cover the outer peripheral portion of the inner housing 2. The outer peripheral cover 3 and the urging element 4 for urging the inner housing 2 to the bottom of the hollow portion 3a of the outer peripheral cover 3 in the insertion direction of the pin 11 and the pin provided in the hollow portion 2b of the inner housing 2. When inserting the pin 11 into the insertion hole 2a, the pin 11 is pinched while moving the inner housing 2 in the pull-out direction, and when the pin 11 is pulled out from the pinched state, the pin is moved while moving the inner housing 2 in the pull-out direction. It is provided with a pin pinching element 5 for releasing the pinching state of 11.

In such a technical means, a metal such as SUS is used, although the molding material of the inner housing 2 and the outer peripheral cover 3 is arbitrary.
In this example, the inner housing 2 may have a pin insertion hole 2a and a hollow portion 2b, and the inner housing 2 may be composed of one part or a combination of a plurality of parts. It may be configured.
Further, the outer peripheral cover 3 has a hollow portion 3a in which the inner housing 2 is slidably stored, and broadly includes a cavity portion 3a that is housed so as to cover the outer peripheral portion of the inner housing 2. Here, the inner housing 2 may be completely housed in the cavity 3a of the outer peripheral cover 3, or a part of the inner housing 2 may be arranged so as to protrude from the cavity 3a. include. However, in the latter aspect, when the user grips the outer peripheral cover 3 of the pin fastener 1, the outer peripheral cover 3 is outward from the peripheral edge of the opening 3b end so as not to simultaneously grip the protruding portion of the inner housing 2. It is preferable to select so that it does not squeeze out. Further, the shape of the outer peripheral cover 3 is cylindrical, and the outer peripheral shape includes an arbitrary shape such as a spherical shape or a star shape.

Further, the urging element 4 urges the inner housing 2 toward the insertion direction side of the pin 11 with respect to the hollow portion 3a of the outer peripheral cover 3, and when the inner housing 2 moves in the pull-out direction, when the pin 11 is detached. It suffices to function so as to return the inner housing 2 into the cavity 3a of the outer peripheral cover 3.
Further, the pin pinching element 5 sandwiches the pin 11 inserted from the pin insertion hole 2a of the inner housing 2 and releases the pin 11 pinching state when the pin 11 is pulled out. When the pin 11 is inserted, the pin 11 is pulled out. The pin 11 may be pinched or the pin 11 may be released from the pinched state while sometimes moving the inner housing 2 in the pull-out direction. For example, the circumferences of the plurality of spheres 5a and the hollow portion 2b of the inner housing 2 It may be configured in combination with the inclined surface 5c formed on the wall surface, or may be an embodiment using a sphere holder 5b that slidably holds the sphere 5a.

Further, the method of using the pin fastener 1 according to this example is as follows.
First, a case where the pinning decoration body 10 is attached to the pinning tool 1 will be described. As shown in FIG. 1A, the pin 11 of the pinning decoration body 10 is inserted into the pin insertion hole 2a of the inner housing 2. do it. At this time, the pin 11 is inserted into the inner housing 2 through the pin insertion hole 2a and reaches the pin holding element 5 built in the inner housing 2. Here, assuming that the pin holding element 5 is of an embodiment composed of, for example, a plurality of spheres 5a and an inclined surface 5c, the pin 11 advances through a passage portion surrounded by the plurality of spheres 5a, and a plurality of spheres 5a are formed. The sphere 5a is pushed outward by the pin 11 and slides along the inclined surface 5c formed on the inner wall surface of the hollow portion 2b. At this time, the pressing force acts on the inclined surface 5c from the plurality of spheres 5a in the direction orthogonal to the inclined surface 5c, and the component force component of the pressing force toward the pull-out direction of the pin 11 causes the inner housing 2 to have a pressing force. A part is drawn out as shown by the virtual line in FIG. 2 (a). Then, the pin 11 passes through the passage portion surrounded by the plurality of spheres 5a, and the pin 11 is sandwiched when the plurality of spheres 5a are pressed against a predetermined position on the inclined surface 5c. As a result, the pin 11 of the pinning decoration 10 is held in the restrained state in the pinning tool 1.

On the contrary, when the pinning decoration 10 is removed from the pinning tool 1, the pin 11 of the pinning decoration 10 may be pulled out in the direction of the arrow as shown in FIG. 1 (b). At this time, since the pin holding element 5 holds the pin 11, when the pin 11 is pulled out in the pulling direction, the inner housing 2 is pulled out from the outer peripheral cover 3 against the urging force of the urging element 4. Along with this, the inclined surface 5c of the inner housing 2 is displaced in the drawing direction, and the sliding resistance between the plurality of spheres 5a and the inclined surface 5c is reduced. Therefore, the holding force of the pin 11 by the plurality of spheres 5a is weakened, and the pin 11 is pulled out from the pin holding element 5. When removing the pinning decoration 10, if the pin 11 to be pulled out is caught by the pin holding element 5 of the pin fastener 1, the pin 11 is pushed in while rotating and pulled out again. It suffices to perform the operation.

Next, a typical mode or a preferable mode of the present embodiment will be described.
First, as a preferred embodiment of the inner housing 2, there is an embodiment in which the hollow portion 2b is provided on the side opposite to the pin insertion hole 2a and has a pin receiving element 6 for receiving the inserted pin 11.
In this example, the pin receiving element 6 is added to the opposite side of the pin insertion hole 2a in the hollow portion 2b of the inner housing 2. Here, the pin receiving element 6 may be provided in the hollow portion 2b of the inner housing 2, may be fixedly provided in the inner housing 2, or may be provided on the outer peripheral cover 3 side. It may be arranged so as to project so as to be relatively movable in the inner housing 2 through a through hole at the end of the housing 2. Further, the pin receiving element 6 provided on the outer peripheral cover 3 side may penetrate the center of the bottom of the outer peripheral cover 3 and project to the outside, and also broadly includes a mode in which the pin receiving element 6 penetrates but does not project to the outside or does not penetrate. .. As for the method of fixing the pin receiving element 6 to the center of the bottom of the outer peripheral cover 3, a screw type, brazing, or the like may be appropriately selected.

Further, as a preferred embodiment of the outer peripheral cover 3, there is an embodiment in which the insertion port 3c of the pin 11 is provided at the bottom of the cavity 3a. This example is a mode in which the tip end side of the pin 11 inserted into the pin fastener 1 can be inserted from the insertion port 3c of the outer peripheral cover 3, as compared with the mode in which the outer peripheral cover 3 does not have the insertion port 3c of the pin 11. Therefore, it is preferable that the outer shape of the outer peripheral cover 3 can be reduced.

Further, as a typical embodiment of the pin holding element 5, as described above, an inclined surface 5c formed so as to reduce the diameter of the inner wall surface of the hollow portion 2b of the inner housing 2 toward the pin insertion hole 2a side. It has a plurality of spheres 5a slidably accommodated along the inclined surface 5c, and is pinned by the plurality of spheres 5a sliding along the inclined surface 5c when the pin 11 is inserted into the pin insertion hole 2a. An aspect of sandwiching the eleven is mentioned. The degree of inclination of the inclined surface 5c may be appropriately selected, but if the inclination angle of the inclined surface 5c with respect to the center line direction of the cavity 3a of the outer peripheral covering 3 is θ, it is about 10 ° to 20 °. It is preferable to select. When θ is selected to be less than 10 °, when the pin 11 is inserted, the sliding resistance between the plurality of spheres 5a pushed away by the pin 11 and the inclined surface 5c tends to become extremely large, and the pinning decoration 10 On the other hand, if θ is selected to exceed 20 °, the sliding resistance between the plurality of spheres 5a pushed away by the pin 11 and the inclined surface 5c becomes small. There is a concern that the pin 11 is easily held by the pin holding element 5 and the pinning decoration 10 is easily removed.
In this example, as the pin holding element 5, a plurality of spheres 5a and an inclined surface 5c formed on the inner wall surface of the hollow portion 2b of the inner housing 2 are combined, and FIGS. 1 (a) and 1 (b) show. As shown, when the pin 11 is inserted and when the pin 11 is detached, the pin 11 is pinched and the pin 11 is released while the inner housing 2 is moved in the drawer direction.

Further, as a preferred embodiment of the pin holding element 5, as shown in FIG. 1A, a plurality of spheres 5a are slidably provided in the hollow portion 2b of the inner housing 2 and a plurality of spheres 5a are placed on the outer circumference in the hollow portion 2b. Non-contact is maintained at the central portion along the center line of the cover 3, and movement of the outer peripheral cover 3 in the center line direction is restricted, and movement is possible in at least the radial direction of the outer peripheral cover 3 in the radial direction and the circumferential direction.

This example is an effective embodiment in which a sphere holder 5b is used and a situation in which a plurality of spheres 5a are immobile in the hollow portion 2b of the inner housing 2 is avoided.

Further, in the embodiment in which the inner housing 2 has the pin receiving element 6, as a typical embodiment of the spherical holder 5b, the inner housing 2 is formed in an inverted truncated cone shape along the inclined surface 5c shape of the inner housing 2, and is formed with the pin receiving element 6. An embodiment in which they are arranged separately can be mentioned. This example is a spherical holder 5b separated from the pin receiving element 6, and is a hollow portion of the hollow portion 2b of the inner housing 2 surrounded by an inclined surface 5c located on the pin insertion hole 2a side of the pin receiving element 6. It is arranged as an independent part in 2b.
Further, in the embodiment in which the inner housing 2 has the pin receiving element 6, another typical embodiment of the spherical holder 5b is a holder body formed in an inverted truncated cone shape along the inclined surface 5c shape of the inner housing 2. An embodiment having a holder guide portion that protrudes from the holder body toward the pin receiving element 6 and is slidably guided in the pin receiving element 6 can be mentioned. This example is a mode in which the spherical holder 5b is guided and moved along the pin receiving element 6, and the holder guide portion is not limited to a cylindrical one that is slidably fitted to the pin receiving element 6, and a plurality of guides are provided. It may be composed of legs.

An embodiment in which the guide protrusions are slidably engaged with each other can be mentioned. This example is a preferable mode for guiding and moving the sphere holder 5b along the pin receiving element 6, and the sphere holder 5b is slid in a derotated state to smoothly perform the sliding operation of the sphere holder 5b. Is possible. Here, the guide protrusions may be provided at a plurality of places, but may be provided at one place. Further, the guide groove is not limited to the bottomed groove, but also includes a slit.
In this example, while the force is applied in the direction of pulling out the pin 11, the sphere 5a in the sphere holder 5b keeps pressing and holding the pin 11, and it is proportional to the tilt angle θ of the inclined surface 5c to pull out as it is. It is necessary to apply the force that has been applied. At this time, the inclination angle θ of the inclined surface 5c is an important parameter for allowing the spherical holder 5b to move together with the pin 11 and for pulling out only the pin 11 without difficulty if further force is applied. That is, it is not preferable that the inclination angle θ of the inclined surface 5c is too wide or too narrow to move the sphere holder 5b when the pin 11 is pulled out. The inclination angle θ is preferably 10 ° to 20 °.

Further, as a preferred embodiment of the inner housing 2, when the pin 11 is not inserted, the inner housing 2 is housed in the cavity 3a so as not to protrude from the outer surface of the outer peripheral cover 3. In this example, the inner housing 2 does not become an external protrusion protruding from the outer peripheral cover 3.
Further, as another preferred embodiment of the inner housing 2, when the pin 11 is not inserted, a surface portion having a surface portion facing the opening 3b of the cavity portion 3a of the outer peripheral cover 3 and being connected to the outer surface portion of the outer peripheral cover 3 is provided.

In this example, the pin fastener 1 can be used as a part of the decorative body, and from a different point of view, it is effective in using the decorative body such as a pearl as a decorative cover body and changing it to a decorative pin fastener. It can also be regarded as a technology. In this aspect, the decorative cover body may be the whole or a part of the outer peripheral cover 3.

<Stopper wall>
Further, the stopper wall 60 is composed of a crosspiece formed at the tip of the cylindrical tube 41 of the pin receiving tube 40, and in this example, the stopper wall 60 is arranged so as to face the second cavity portion 33b side of the cover main body 31. There is.

<Inner case>
In this example, the inner case 50 is integrally molded using, for example, a steel material such as SUS, and is slidably accommodated along the center line of the cavity 33 of the outer cover 30 as shown in FIG. 3 (b). It is composed of a cylindrical hollow cylinder 51 to be formed. The hollow tubular body 51 of this example has a storage chamber 54 as a hollow portion inside, and a pin insertion hole 52 into which a pin 110 of a decorative body 100 with a pin is inserted is formed at one end of a side wall portion. A through hole 53 into which the pin receiving cylinder 40 is slidably inserted is formed in the other end side wall portion.
In particular, in this example, since it is necessary to incorporate a coil spring 70, a component of the pin holding mechanism 80, and the like into the hollow cylinder 51 which is the inner case 50, for example, a through hole 53 of the hollow cylinder 51 is opened. A method is adopted in which one end side wall portion is composed of a removable lid member 51b.
Further, in this example, the storage chamber 54 is slightly larger than the first storage chamber 54a and the first storage chamber 54a having an inner diameter space in which the pin receiving cylinder 40 and the stopper wall 60 can be accommodated in a non-contact manner. The area is divided into a second storage chamber 54b having an inner diameter and having a space in which the inner diameter is gradually reduced toward the pin insertion hole 52 side.

In this example, the hollow cylinder 51 has a small diameter portion accommodated in the first hollow portion 33a of the outer cover 30 and a large diameter portion in the second outer cover 30 with the stepped portion 55b of the second stage as a boundary. It is accommodated in the cavity 33b.

<Coil spring>
In this example, as shown in FIGS. 2 (b) and 3 (c), the coil spring 70 has a side wall portion at one end and a pin receiving cylinder 40 in which a through hole 53 of the hollow cylinder 51, which is an inner case 50, is opened. Both ends are hooked between the stopper wall 60 provided at the tip of the pin receiving cylinder 40 and wound around the pin receiving cylinder 40.

<Pin pinching mechanism>
In this example, as shown in FIGS. 4A and 3D, a plurality of pin holding mechanisms 80 are provided in the second storage chamber 54b of the hollow cylinder 51 which is the inner case 50 (three in this example). By accommodating the sphere 81 (pieces) and using the structure of the second accommodating chamber 54b, the pin 110 of the decorative body 100 with a pin inserted into the pin insertion hole 52 of the inner case 50 is sandwiched at a predetermined position. It is something to do.
In this example, as shown in FIGS. 4 (b) to 4 (d), the second storage chamber 54b has a structure in which the inner diameter is reduced as the distance from the first storage chamber 54a is increased, but the cross section thereof. As the surface shape, a triangular shape of Ruro is selected, and a substantially U-shaped guide groove 54 m is formed in the vicinity of the apex of the triangular shape of Ruro to stably accommodate a plurality of spheres 81. A peripheral wall surrounding the second accommodation chamber 54b (all peripheral walls including the guide concave groove 54 m) is formed with an inclined surface 82 inclined in a direction of reducing the diameter toward the pin insertion hole 52 side. In the accommodation chamber 54b, when the pin 110 inserted from the pin insertion hole 52 enters the passage portion surrounded by the plurality of spheres 81, the plurality of spheres 81 move outward as the pin 110 enters. It is pushed away and slidably moves along the inclined surface 82 of the guide concave groove 54 m, and the pin 110 is held in a state of being pressed against the three spheres 81 at a predetermined position.
The inclination angle θ of the inclined surface 82 with respect to the center line direction of the hollow cylinder 51 may be appropriately selected, but is in the range of 10 ° to 20 ° in consideration of the sliding resistance between the sphere 81 and the inclined surface 82. It is selected as appropriate in.

-Manufacturing method of pin fasteners-
As shown in FIGS. 3 (a) to 3 (d), in order to manufacture the pin fastener 20 by using each component of the pin fastener 20, the procedure as follows may be performed.
First, of the hollow tubular body 51 as the inner case 50, the lid member 51b having the through hole 53 is temporarily removed, and a plurality of spheres 81 are accommodated in the second accommodating chamber 54b of the hollow tubular body 51. , One end of the coil spring 70 is placed on the stopper wall 60 attached to the pin receiving cylinder 40, and the pin receiving cylinder 40 and the coil spring 70 are inserted into the hollow cylinder 51 from the opening from which the lid member 51b of the hollow cylinder 51 is removed. After accommodating in the accommodating chamber 54a and the second accommodating chamber 54b, the opening of the hollow tubular body 51 is closed with the lid member 51b. At this time, the pin receiving cylinder 40 is inserted into the through hole 53 of the lid member 51b, and the other end of the coil spring 70 is pushed by the lid member 51b. Next, the inner case 50 in which each part was incorporated was inserted into the cavity 33 from the opening 32 side of the outer cover 30, and the pin receiving cylinder 40 protruding from the inner case 50 was opened at the bottom 34 of the outer cover 30. It is inserted into the insertion hole 35 and is arranged so as to project to the outside of the outer cover 30. In this state, the pin receiving cylinder 40 is fixed to the edge of the insertion hole 35 so that the protruding dimension of the pin receiving cylinder 40 becomes a predetermined value, and the inner case 50 is accommodated in the cavity 33 of the outer cover 30. It should be.

-How to use the pin fasteners-
<Mounting operation of decorative body with pin>
When the decorative body 100 with a pin is attached to the pin fastener 20, as shown in FIGS. 2 (b) and 5 (a), the pin of the decorative body 100 with a pin is inserted into the pin insertion hole 52 of the pin fastener 20. 110 may be inserted.
At this time, the pin 110 is inserted into the inner case 50 through the pin insertion hole 52, and advances through the passage portion surrounded by the plurality of spheres 81 built in the inner case 50. Then, the plurality of spheres 81 are pushed outward as the pin 110 is pushed in, and as shown in FIGS. 4 (a) and 5 (b), the plurality of spheres 81 are formed on the inclined surface 82 surrounding the circumference of the second storage chamber 54b. It slides along the insertion direction of the pin 110. In this state, since the plurality of spheres 81 are pressed outward against the inclined surface 82, the inner case 50 is in a state of slightly protruding in the direction of being pulled out from the hollow portion 33 of the outer cover 30. Then, the pin 110 passes through the passage portion surrounded by the plurality of spheres 81 and is received by the pin receiving cylinder 40, and when the plurality of spheres 81 are pressed into a predetermined position on the inclined surface 82, the pin 110 is pressed. Hold it in the same state. As a result, the pin 110 of the decorative body 100 with a pin is held in a restrained state in the pin fastener 20.
In this example, even if the thickness of the pin 110 is different, the amount of movement of the plurality of spheres 81 to the outside changes according to the thickness of the pin 110, and the inner case 50 is accompanied by this. The withdrawal amount changes, and a plurality of spheres 81 hold the pin 110 in a pressurized state.

<Removal operation of decorative body with pin>
On the contrary, when the decorative body 100 with a pin is removed from the pin fastener 20, the pin 110 of the decorative body 100 with a pin is pulled out in the direction of the arrow as shown in FIGS. 2 (b) and 5 (c). do it. At this time, since the plurality of spheres 81 of the pin holding mechanism 80 pressurize and hold the pin 110, even if the pin 110 is to be pulled out in the pulling direction, the plurality of spheres are moved along with the movement of the pin 110 in the pulling direction. The 81 slides along the inclined surface 82 in a direction in which the diameter is reduced, and the pressure holding force of the pin 110 by the plurality of spheres 81 is further increased. Therefore, as shown in FIG. 5D, when the force in the pull-out direction of the pin 110 is further strengthened, the restrained state by the pin 110 by the plurality of spheres 81 is maintained, and the inner case 50 becomes the urging force of the coil spring 70. It is pulled out by the pin 110 against it, and a part of the inner case 50 is arranged so as to project from the cavity 33 of the outer cover 30. In this state, the pressure holding force of the pin 110 by the plurality of spheres 81 is still strong, so even if the pin 110 is to be pulled out as it is, it is difficult to pull it out.
Therefore, in this example, if the pin 110 is once pushed in as shown in FIG. 6 (a) while rotating the pin 110 as shown in FIG. 5 (e), the pin 110 is rotated. Since the sliding resistance between the pin 110 and the plurality of spheres 81 is reduced, and further, the plurality of spheres 81 slide in the direction of increasing the diameter along the inclined surface 82 as the pin 110 is pushed in. The pressure holding force of the pin 110 by the plurality of spheres 81 is temporarily weakened. In this state, when the pin 110 is pulled out again in the direction of the arrow as shown in FIG. 6 (b), the pin 110 is pulled from the passage portion surrounded by the plurality of spheres 81 as shown in FIG. 6 (c). After being pulled out, it is pulled out from the pin insertion hole 52 of the inner case 50. After that, when the pin 110 is completely pulled out from the pin fastener 20, as shown in FIG. 6D, a plurality of spheres 81 located near the apex of the triangle of Ruro are formed as the pin 110 rotates. The inner case 50 moves in the direction of rotation, whereby the inner case 50 rotates while twisting and deforming the coil spring 70. Therefore, when the pin 110 is pulled out, the restrained state of the plurality of spheres 81 by the pin 110 is released, and the coil spring 70 is released. After the inner case 50 rotates a little due to the return action of the twisting deformation, the inner case 50 returns to the inside of the cavity 33 of the outer cover 30 by the urging force of the coil spring 70 as shown in FIG. 6 (e). Return to the initial position.

-Ingenuity of decorative body with pin-
As shown in FIG. 7A, the pinned decorative body 100 has a constriction 111 having a small-diameter recess in a part of the pin 110 so that the pin 110 cannot be easily removed from the pin fastener 20. There is an embodiment of providing the above. In this case, when the pin 110 is inserted into the pin fastener 20, as shown in FIG. 7B, a pressure holding force P acts on the pin 110 from a plurality of spheres 81. Even if an external force in the pull-out direction suddenly acts on the pin 110 and the pin 110 moves in the pull-out direction, as shown in FIG. 7 (c), when a plurality of spheres 81 engage with the constriction 111 of the pin 110, the pin The movement of the 110 in the pull-out direction is effectively suppressed, and the situation where the pin 110 is easily disengaged is avoided.
When such a decorative body 100 with a pin is used, the operation of attaching and detaching the decorative body 100 with a pin to the pin fastener 20 may be performed as shown in FIGS. 5 and 6, and the pin without a constriction 111 may be performed. The operability of attaching and detaching the decorative body 100 with a pin is better maintained as compared with the case of using the decorative body with a pin.

In this example, the inner case 50 behaves as if it is slightly pulled out from the outer cover 30 by inserting the pin 110 into the pin insertion hole 52, but the withdrawal amount of the inner case 50 is a passage portion surrounded by a plurality of spheres 81. It is presumed that it is roughly proportional to the size of the gap.
That is, as shown in FIGS. 7 (d) and 7 (e), the gaps between the plurality of spheres 81 are expanded by inserting the pins 110 into the inner case 50, the plurality of spheres 81 rub against the inclined surface 82, and the inclined surface 82 It is presumed that the pressing force Q acts in the vertical direction with respect to the above, and the inner case 50 is slid in the drawing direction by the extraction direction component Q1 of the pressing force Q.
Here, as shown in FIG. 7 (d), assuming that the diameter of the inscribed circle in the gap between the passage portions of the plurality of spheres 81 is h (for example, 0.4 ψ (corresponding to mm)), the constriction 111 of the pin 110 You can roughly match the size. In the case of this example, the pin 110 is not held by the pin fastener 20 with the pin 110 of h or less. Then, in the pin 110 having a diameter larger than h (however, less than 1.0 ψ), the inner case 50 is once pulled out from the outer cover 30 in a state where a plurality of spheres 81 are fitted in the constriction 111 of the pin 110. Also exhibits the behavior of returning to the original flat or near-flat state facing the opening 32 of the outer cover 30.
As described above, in this example, the larger the gap between the thickness of the pin 110 and the constriction 111, that is, the smaller the diameter of the constriction 111, the more difficult it is for the pin 110 to come off from the pin fastener 20. In other words, the force for pulling out the pin 110 required when removing the decorative body 100 with a pin is increased. On the contrary, when the constriction 111 becomes shallow or the pin 110 having no constriction is used, the pin 110 can be easily pulled out from the pin fastener 20, so that the inclination angle θ of the inclined surface 82 is set small. is required.

In this example, as shown in FIGS. 11A to 11D, the spherical holder 90 has an inverted truncated cone shape along the inclined surface shape of the second storage chamber 54b in the hollow tubular body 51 which is the inner case 50. Has a holder body 91 of. Here, the holder main body 91 is provided separately from the pin receiving cylinder 40, and is connected between the disc-shaped top 91a and the disc-shaped bottom 91b having a diameter smaller than that of the top 91a by the body portion 91c. A through hole 92 through which the pin 110 of the decorative body 100 with a pin passes is formed in the center of the top portion 91a, the body portion 91c, and the bottom portion 91b, and the body portion 91c is formed with respect to the center line of the through hole 92. A plurality of (three in this example) spherical holding holes 93 are opened at substantially equal angular intervals in the radial direction.
In this example, the sphere holder 90 is slidably provided in the second storage chamber 54b, and the plurality of spheres 81 held in the sphere holding holes 93 are not in contact with each other at the central portion along the center line of the through hole 92. In addition to restricting the movement of the through hole 92 in the center line direction and the circumferential direction, the through hole 92 is made movable in the radial direction. In this example, since the sphere holder 90 adopts an aspect of restricting the movement of the plurality of spheres 81 in the circumferential direction of the through hole 92, the work of incorporating the plurality of spheres 81 into the sphere holder 90 can be easily performed. Is preferable. Further, although the sphere holder 90 restricts the movement of the plurality of spheres 81 in the circumferential direction, a plurality of sphere holders 90 are rotatable about the center line direction of the through hole 92 with respect to the second accommodation chamber 54b. The sphere 81 of the above is movable in the circumferential direction with the rotation of the sphere holder 90. The structure of the sphere holder 90 may be such that the movement of the plurality of spheres 81 in the circumferential direction is not restricted, and the sphere holder 90 is arranged so as not to rotate with respect to the second storage chamber 54b. It may have been done.

-Manufacturing method of pin fasteners-
As shown in FIGS. 9 to 11, in order to manufacture the pin fastener 20 by using each component of the pin fastener 20, the procedure as follows may be performed.
First, of the hollow cylinder 51 as the inner case 50, the lid member 51b having the through hole 53 is once removed, and the sphere holder in which the three spheres 81 are held in the second storage chamber 54b of the hollow cylinder 51. 90 is accommodated, and then one end of the coil spring 70 is placed on the stopper wall 60 attached to the pin receiving cylinder 40, and the pin receiving cylinder 40 and the coil spring 70 are placed from the opening from which the lid member 51b of the hollow cylinder 51 is removed. Is housed in the first storage chamber 54a and the second storage chamber 54b of the hollow cylinder 51, and then the opening of the cylindrical tube 51a of the hollow cylinder 51 is closed with the lid member 51b. At this time, the pin receiving cylinder 40 is inserted into the through hole 53 of the lid member 51b, and the other end of the coil spring 70 is pushed by the lid member 51b. Next, the inner case 50 in which each part was incorporated was inserted into the cavity 33 from the opening 32 side of the outer cover 30, and the pin receiving cylinder 40 protruding from the inner case 50 was opened at the bottom 34 of the outer cover 30. It is connected to the insertion hole 35. In this state, the inner case 50 may be accommodated in the cavity 33 of the outer cover 30.

-How to use the pin fasteners-
<Mounting operation of decorative body with pin>
When the decorative body 100 with a pin is attached to the pin fastener 20, the pin 110 of the decorative body 100 with a pin may be inserted into the pin insertion hole 52 of the pin fastener 20 as shown in FIG. 8 (a). ..
At this time, the pin 110 is inserted into the inner case 50 through the pin insertion hole 52, and advances through the through hole 92 of the spherical holder 90 built in the inner case 50. Then, the plurality of spheres 81 held in the sphere holder 90 are pushed outward (corresponding to the radial direction of the through hole 92) as the pin 110 is pushed in, and the inclined surface surrounding the circumference of the second storage chamber 54b. It slides along the 82 in the insertion direction of the pin 110. In this state, since the plurality of spheres 81 are pressed outward against the inclined surface 82, the inner case 50 is in a state of slightly protruding in the direction of being pulled out from the hollow portion 33 of the outer cover 30. Then, when the pin 110 passes through the through hole 92 of the sphere holder 90 and is received by the pin receiving cylinder 40, and the plurality of spheres 81 are pressed against the predetermined positions of the inclined surface 82, the pin 110 is pressurized. Hold it. As a result, the pin 110 of the decorative body 100 with a pin is held in a restrained state in the pin fastener 20.

<Removal operation of decorative body with pin>
On the contrary, when the decorative body 100 with a pin is removed from the pin fastener 20, the pin 110 of the decorative body 100 with a pin may be pulled out in the direction of the arrow as shown in FIG. 8 (b). At this time, since the plurality of spheres 81 held by the sphere holder 90 of the pin holding mechanism 80 pressurize and hold the pin 110, even if the pin 110 is pulled out in the pulling direction, the pin 110 is pulled out. Along with the movement of the plurality of spheres 81, the plurality of spheres 81 slide in a direction in which the diameter is reduced along the inclined surface 82, and the pressure holding force of the pin 110 by the plurality of spheres 81 is further increased. Therefore, when the force in the pull-out direction of the pin 110 is further strengthened, the restrained state by the pin 110 by the plurality of spheres 81 held in the sphere holder 90 is maintained, and the inner case 50 resists the urging force of the coil spring 70. It is pulled out by a pin 110, and a part of the inner case 50 is arranged so as to project from the cavity 33 of the outer cover 30 by a dimension m. In this state, the pressure holding force of the pin 110 by the plurality of spheres 81 is still strong, so even if the pin 110 is to be pulled out as it is, it is difficult to pull it out.
However, when a part of the inner case 50 protrudes from the cavity 33 of the outer cover 30 by m, when the top portion 91a of the spherical holder 90 abuts on the end of the pin receiving cylinder 40, the inside of the cavity 33 of the inner case 50 Since the relative movement of the sphere holder 90 is restricted, the movement of the plurality of spheres 81 held in the sphere holder 90 in the center line direction is restricted. Therefore, when the inner case 50 further protrudes from the hollow portion 33 of the outer cover 30 after the relative movement of the sphere holder 90 is restricted, the plurality of spheres 81 held by the sphere holder 90 have an inclined surface 82. The pressure and holding force of the pin 110 by the plurality of spheres 81 are temporarily weakened due to the relative movement in the direction of increasing the diameter. In this state, when the pin 110 is further pulled out, the pin 110 is pulled out from the through hole 92 of the spherical holder 90 and then pulled out from the pin insertion hole 52 of the inner case 50.
After that, when the pin 110 is completely pulled out from the pin fastener 20, the inner case 50 returns to the hollow portion 33 of the outer cover 30 by the urging force of the coil spring 70 and returns to the initial position.

◎ Deformation form 2-1
In the second embodiment, the inner case 50 has a structure completely accommodated in the cavity 33 of the outer cover 30, but the present invention is not limited to this, and is shown in FIGS. 12 (a) and 12 (b), for example. As described above, for example, a projecting portion 57 projecting from the hollow portion 33 of the outer cover 30 is formed on the outside of the damming wall 56 of the hollow tubular body 51 which is the inner case 50, and further, the projecting portion 57 is formed with a crossguard of the cover main body 31. The collar portion 57a corresponding to the portion 31a may be formed.
Here, the protruding dimension of the protruding portion 57 from the end of the cover main body 31 may be appropriately selected, but if the protruding dimension of the protruding portion 57 is too large, when the user grips the outer cover 30, the inner cover 30 is inner. There is a possibility that the protruding portion 57 of the case 50 is also gripped together, and in this case, the operation of temporarily pulling out the inner case 50 when the pin 110 is pulled out is impaired, which is not preferable. Further, it is preferable that the flange portion 57a of the protruding portion 57 does not project outward from the flange portion 57a of the cover main body 31 of the outer cover 30. By doing so, when the user grips the outer cover 30, it is possible to suppress the concern that the flange portion 57a of the protruding portion 57 of the inner case 50 is gripped together.

FIG. 13 (a) is a cross-sectional explanatory view showing a state before mounting the decorative body with a pin of the pin fastener according to the third embodiment, and FIG. 13 (b) shows a state when the decorative body with a pin is removed from the pin fastener. It is sectional drawing explanatory drawing.
-Overall configuration of pin fasteners-
In FIG. 13A, the basic configuration of the pin fastener 20 is substantially the same as that of the second embodiment, but the spherical holder 90 has a different configuration from the second embodiment. The components similar to those of the second embodiment are designated by the same reference numerals as those of the second embodiment, and detailed description thereof will be omitted here.
In this example, the spherical holder 90 forms a through hole 92 in the center of the holder main body 91 (which includes a top portion 91a, a bottom portion 91b, and a body portion 91c) and penetrates the body portion 91c, as in the second embodiment. It has a plurality of spherical holding holes 93 extending radially from the holes 92, but unlike the second embodiment, a cylindrical holder guide portion 94 is provided around the through hole 92 of the top portion 91a of the holder main body 91. It is provided. The holder guide portion 94 projects toward the pin receiving cylinder 40 side and is slidably guided in the cylindrical tube 41 of the pin receiving cylinder 40.
In this example, the holder guide portion 94 is composed of a cylindrical member, but is not necessarily limited to this, and a plurality of holder guide legs are slidably guided in the cylindrical tube 41. It may be arranged as follows.
According to this example, the pin fastener 20 can be used substantially in the same manner as in the second embodiment, but the holder guide portion 94 can slide along the center line direction of the pin receiving cylinder 40. In the accommodation chamber 54 of the inner case 50, the spherical holder 90 moves along the center line direction of the inner case 50 while maintaining a stable posture. Therefore, it is possible to apply the pressure holding force of the plurality of spheres 81 to the pins 110 of the decorative body 100 with pins in a well-balanced manner.

◎ Embodiment 4
FIG. 14 (a) is a cross-sectional explanatory view showing a state before mounting the decorative body with a pin of the pin fastener according to the fourth embodiment, and FIG. 14 (b) shows a pin receiving cylinder and a spherical holder which are components of the pin fastener. It is a perspective explanatory drawing which shows.
-Overall configuration of pin fasteners-
In FIG. 14A, the basic configuration of the pin fastener 20 is substantially the same as that of the third embodiment, but the spherical holder 90 has a different configuration from the third embodiment. The components similar to those of the third embodiment are designated by the same reference numerals as those of the third embodiment, and detailed description thereof will be omitted here.
In this example, the sphere holder 90 includes a holder body 91, a through hole 92, a sphere holding hole 93, and a holder guide portion 94, as in the third embodiment, but the holder guide portion 94 and the pin receiving cylinder 40 are provided. Has a different configuration from the third embodiment.
In this example, as shown in FIG. 14B, the holder guide portion 94 has a pair of holder guide legs 94a arranged so as to face each other around the through hole 92 in the top portion 91a of the holder main body 91, and each holder. A locking claw 94b bent toward the opposite side to the opposite direction is formed at the tip of the guide leg 94a.
Further, the pin receiving cylinder 40 has an annular engaging groove 42 formed in the peripheral wall at the tip end portion of the cylindrical tube 41, and is further cut into the cylindrical tube 41 from the end portion located on the opposite side of the stopper wall 60. A pair of strip-shaped guide slits 43 are formed, and the bottom of each guide slit 43 functions as a locking wall 44.
In this example, the pair of holder guide legs 94a of the holder guide portion 94 are slidably guided in the cylindrical tube 41 of the pin receiving tube 40, and the locking claw 94b slides along the guide slit 43 of the cylindrical tube 41. Then, it is locked to the locking wall 44 to stop the movement.

According to this example, when the pin 110 of the decorative body 100 with a pin is attached to the pin fastener 20, the operation is substantially the same as in the third embodiment, but the decorative body 100 with a pin is removed from the pin fastener 20. In some cases, the action is slightly different from that of the third embodiment.
That is, when the decorative body 100 with a pin is removed from the pin fastener 20, the pin 110 of the decorative body 100 with a pin may be pulled out in the direction of the arrow as shown in FIG. 15 (a). At this time, since the plurality of spheres 81 held by the sphere holder 90 of the pin holding mechanism 80 pressurize and hold the pin 110, even if the pin 110 is pulled out in the pulling direction, the pin 110 is pulled out. When the plurality of spheres 81 slide in a direction in which the diameter is reduced along the inclined surface 82 with the movement of the spheres 81, the pressure holding force of the pin 110 by the plurality of spheres 81 is further increased.
Here, when the sphere holder 90 moves in the pulling direction as the pin 110 is pulled out, the sphere holder 90 hits the dam wall 56, and thereafter, the locking claw 94b of the holder guide leg 94a of the holder guide portion 94 receives the pin. The inner case 50 is arranged so as to project from the cavity 33 of the outer cover 30 by m1 until the guide slit 43 of the cylinder 40 slides and hits the locking wall 44. During this time, although the inner case 50 is pulled out, since the sphere holder 90 is also pulled out in the inner case 50, the pressure holding force of the pin 110 by the plurality of spheres 81 does not change, and the pin 110 should be pulled out as it is. Even so, it is difficult to pull it out.

However, when the pin 110 is further pulled out in the pulling direction while the position of the spherical holder 90 is stopped, as shown in FIG. 15B, the inner case 50 opposes the urging force of the coil spring 70 and the inner case 50 becomes the outer cover 30. It is assumed that the cavity 33 is pulled out to a position further protruding by m2 (m2> m1).
In this state, when the inner case 50 further protrudes from the cavity 33 of the outer cover 30 after the relative movement of the sphere holder 90 is restricted, the plurality of spheres 81 held by the sphere holder 90 have an inclined surface. The relative movement is performed in the direction of increasing the diameter with respect to the 82, and the pressure holding force of the pin 110 by the plurality of spheres 81 is temporarily weakened. In this state, when the pin 110 is further pulled out, the pin 110 is pulled out from the through hole 92 of the spherical holder 90 and then pulled out from the pin insertion hole 52 of the inner case 50.
After that, when the pin 110 is completely pulled out from the pin fastener 20, the inner case 50 returns to the hollow portion 33 of the outer cover 30 by the urging force of the coil spring 70 and returns to the initial position.

I have. The components similar to those of the second embodiment are designated by the same reference numerals as those of the second embodiment, and detailed description thereof will be omitted here.
In this example, as shown in FIGS. 16 to 19, the outer cover 30 has a cover main body 31 substantially similar to that of the second embodiment, but unlike the second embodiment, the opening 32 of the cover main body 31 is formed. For example, a pair of positioning grooves 31c are formed on the inner peripheral edge of the side.
Further, the pin receiving tube 40 is composed of a cylindrical tube 41, and is inserted into the insertion hole 35 formed in the bottom portion 34 of the cover main body 31 in a state of penetrating the cylindrical tube 41, and the tip portion of the cylindrical tube 41 is inserted into the cover main body 31. It is arranged in the cavity 33 of the above. In this example, the cylindrical tube 41 is fixed to the outer surface of the bottom 34 of the outer cover 30 with a fixative 45.
Further, the inner case 50 is made of a hollow tubular body 51 as in the second embodiment, a pin insertion hole 52 is formed in one end side wall portion of the hollow tubular body 51, and a through hole 53 is formed in the other end side wall portion. It is formed, and a storage chamber 54 is secured in the hollow cylinder 51. In this example, the accommodation chamber 54 is provided adjacent to the first accommodation chamber 54a having a space having an inner diameter that allows the pin receiving cylinder 40 and the stopper wall 60 to be accommodated in a non-contact manner, and the first accommodation chamber 54a. A second accommodation chamber 54b having a space whose inner diameter is gradually reduced toward the pin insertion hole 52, and an auxiliary accommodation having a larger diameter than the pin insertion hole 52 and a smaller diameter than the small diameter portion of the second accommodation chamber 54b. The area is divided into the chamber 54c.
Further, a positioning protrusion 58 that engages with the positioning groove 31c of the cover body 31 of the outer cover 30 is formed on the peripheral wall of the hollow cylinder 51 near the pin insertion hole 52.
The stopper wall 60, the coil spring 70, and the pin holding mechanism 80 are substantially the same as those in the second embodiment.
Further, in this example, the auxiliary accommodating chamber 54c accommodates an auxiliary coil spring 71 that urges the spherical holder 90 in the same direction as the urging direction of the coil spring 70 with a urging force weaker than that of the coil spring 70.

-Manufacturing method of pin fasteners-
As shown in FIGS. 16 to 19, in order to manufacture the pin fastener 20 by using each component of the pin fastener 20, the procedure as follows may be performed.
First, of the hollow tubular body 51 as the inner case 50, the lid member 51b having the through hole 53 is temporarily removed, and the auxiliary coil spring 71 is accommodated in the auxiliary accommodating chamber 54c of the hollow tubular body 51. The sphere holder 90 in which the three spheres 81 are held is accommodated in the second accommodation chamber 54b, and then one end of the coil spring 70 is placed on the stopper wall 60 attached to the pin receiving cylinder 40 to form a hollow cylinder. After accommodating the pin receiving tube 40 and the coil spring 70 in the first storage chamber 54a of the hollow tubular body 51 from the opening from which the lid member 51b of the hollow cylinder 51 has been removed, the opening of the cylindrical tube 51a of the hollow tubular body 51 is opened by the lid member 51b. Close it. At this time, the pin receiving cylinder 40 is inserted into the through hole 53 of the lid member 51b, and the other end of the coil spring 70 is pushed by the lid member 51b. Next, the inner case 50 in which each part was incorporated was inserted into the cavity 33 from the opening 32 side of the outer cover 30, and the pin receiving cylinder 40 protruding from the inner case 50 was opened at the bottom 34 of the outer cover 30. It is inserted through the insertion hole 35, and the pin receiving cylinder 40 is fixed to the outer cover 30 using the fixing tool 45. In this state, the inner case 50 may be accommodated in the cavity 33 of the outer cover 30.

-How to use the pin fasteners-
<Mounting operation of decorative body with pin>
When the decorative body 100 with a pin is attached to the pin fastener 20, as shown in FIGS. 16A and 16B, the pin 110 of the decorative body 100 with a pin is inserted into the pin insertion hole 52 of the pin fastener 20. do it.
At this time, the pin 110 is inserted into the inner case 50 from the pin insertion hole 52, passes through the hollow portion of the auxiliary coil spring 71 built in the inner case 50, the through hole 92 of the spherical holder 90, and the pin receiving cylinder 40. It progresses to. Then, when the pin 110 passes through the through hole 92 of the sphere holder 90, the plurality of spheres 81 are pushed outward as the pin 110 is pushed in, along the inclined surface 82 surrounding the circumference of the second storage chamber 54b. Slides in the insertion direction of the pin 110. After that, the pin 110 is received by the pin receiving cylinder 40, and when the plurality of spheres 81 are pressed against the predetermined positions of the inclined surface 82, the pin 110 is held in a pressurized state. As a result, the pin 110 of the decorative body 100 with a pin is held in a restrained state in the pin fastener 20.

<Removal operation of decorative body with pin>
On the contrary, when the decorative body 100 with a pin is removed from the pin fastener 20, the pin 110 of the decorative body 100 with a pin may be pulled out in the direction of the arrow as shown in FIGS. 20 (a) to 20 (f). good. At this time, since the plurality of spheres 81 of the pin holding mechanism 80 pressurize and hold the pin 110, even if the pin 110 is to be pulled out in the pulling direction, the plurality of spheres are moved along with the movement of the pin 110 in the pulling direction. The 81 slides along the inclined surface 82 in a direction in which the diameter is reduced, the pressure holding force of the pin 110 by the plurality of spheres 81 is further increased, and the sphere holder 90 abuts against the bottom of the second storage chamber 54b.
In this state, as shown in FIG. 20 (b), when the force in the pull-out direction of the pin 110 is further strengthened, the restrained state of the pin 110 by the plurality of spheres 81 is maintained, and the inner case 50 has the urging force of the coil spring 70. It is pulled out by the pin 110 against the above, and a part of the inner case 50 is arranged so as to project from the cavity 33 of the outer cover 30.
After that, when a force is applied in the direction of pulling out the pin 110, the sphere 81 in the sphere holder 90 bites into the material of the pin 110 and the inclined surface 82 to hold the pin 110 and the sphere holder 90, but the auxiliary coil spring 71 causes the auxiliary coil spring 71. Otherwise, even if the pulling force of the pin 110 is released, the pin 110 is not released from the bite of the sphere 81, and the pin 110 and the sphere holder 90 may continue to be held. Further, even if the pulling force is released and the pin 110 is released from the restrained state by the sphere 81 in the sphere holder 90 and is pulled out, the sphere holder 90 is moved toward the pin insertion hole 52 by a natural force such as gravity. Once the pin 110 is released from the sphere 81 in the sphere holder 90, the pin 110 is held by the sphere 81 in the sphere holder 90 again, and the pin 110 cannot be pulled out. The auxiliary coil spring 71 is added to keep the sphere holder 90 released from the restrained state by the pin 110 at a position away from the pin insertion hole 52 and to prevent the pin 110 from being held by the sphere 81 in the sphere holder 90 again. Is.

21 (a) and 21 (b) show the main part of the pin fastener according to the sixth embodiment.
In the figure, the pin fastener 20 has a mode different from that of the first to fifth embodiments.
In this example, the outer cover 30 has a bottomed cylindrical cover main body 31 having a hollow portion 33 and a pin receiver fixed to an insertion hole 35 formed in the bottom portion 34 of the cover main body 31 via a flange portion 40f. It is equipped with a cylinder 40.
Further, the inner case 50 is configured by joining two cup-shaped

case parts

50a and 50b at the time of assembly, and the first case part 50a located on the upper middle side of FIG. 21A is the first storage chamber. It has a substantially cylindrical shape that secures 54a, and a through hole 53 through which the pin receiving cylinder 40 is inserted is formed at the bottom thereof, and a second case part 50b located on the lower middle side of FIG. 21 (a). Has a substantially inverted truncated cone shape in the outer shape for securing the second accommodation chamber 54b, and a pin insertion hole 52 is provided at the bottom thereof.
Further, in this example, the inner case 50 is completely housed inside the opening 32 of the cavity 33 of the outer cover 30.

Further, the pin holding mechanism 80 can slide a plurality of spheres 81, an inclined surface 82 formed on the inner wall surface of the second storage chamber 54b, and a plurality of spheres 81, for example, substantially as in the second embodiment. It is provided with a spherical holder 90 to be held in.
However, in the pin pinching mechanism 80 of this example, unlike the second embodiment, a ring tube 85 having a substantially inverted truncated cone shape is arranged on the inner peripheral wall of the second case part 50b, and the inner circumference of the ring tube 85 is arranged. The surface is formed as an inclined surface 82. Further, the spherical holder 90 has a holder body 91 having a substantially inverted truncated cone shape as in the second embodiment, but the top portion 91a of the holder body 91 is positioned so as to be fitted in the pin receiving cylinder 40. A cylinder portion 95 is provided, and the spherical holder 90 is fixed to the pin receiving cylinder 40.
Further, in this example, the top portion 91a of the holder body 91 functions as a stopper wall 60, a coil spring 70 is wound around the pin receiving cylinder 40, and one end of the coil spring 70 is an inner case 50. The inner case 50 is urged in a compressed state by locking it to the bottom of the first case part 50a and locking the other end to the stopper wall 60.

According to the present embodiment, when a decorative body with a pin (not shown) is attached to the pin fastener 20, as shown in FIGS. 21 (a) and 21 (b), the pin of the inner case 50 of the pin fastener 20 is attached. The pin 110 may be inserted into the insertion hole 52. At this time, when the pin 110 reaches the passage portion surrounded by the plurality of spheres 81 of the pin holding mechanism 80, the plurality of spheres 81 held by the sphere holder 90 are pushed outward (through hole 92) as the pin 110 is pushed. It is pushed away (corresponding to the radial direction of) and slides along the inclined surface 82 toward the insertion direction of the pin 110. In this state, since the plurality of spheres 81 are pressed outward against the inclined surface 82, the inner case 50 is slightly pulled out in the direction of being pulled out from the inside of the cavity 33 of the outer cover 30, but in this example. Since the inner case 50 is housed in a position deeper than the opening 32 of the cavity 33 of the outer cover 30, it is in a state of not protruding outward from the opening 32 of the cavity 33 of the outer cover 30. .. Then, when the pin 110 passes through the through hole 92 of the sphere holder 90 and is received by the pin receiving cylinder 40, and the plurality of spheres 81 are pressed against the predetermined positions of the inclined surface 82, the pin 110 is pressurized. Hold it. As a result, the pin 110 of the decorative body with a pin is held in a restrained state in the pin fastener 20.
When removing the decorative body with a pin from the pin fastener 20, the pin 110 sandwiched by the pin sandwiching mechanism 80 may be pulled out while the outer cover 30 is gripped.
