Abstract

A pin-retained clip having a pin holder and a pin with a peripheral groove near its forward end. The pin holder is formed by bending a single oblong bendable sheet-like spring material at the center in its longitudinal direction. When bent, the material has, in a side view, a triangular shape having the top and a pair of inclined sections on both sides of the top. At the top is formed a pin retaining hole for inserting the pin. Also, a pair of holding members is projected from peripheral edge sections in the longitudinal direction of the pin retaining hole. The pair of holding members is projected in the same direction as the inclined sections and has a length that engages into the peripheral groove of the pin inserted in the pin retaining hole. In the clip, inserting the pin requires small force but drawing out the pin requires large force, and the clip can be released from a retained state by simple operation.

Description

Pinned fasteners Technical Field

The present invention relates to a pin-type fastener comprising a pin and a pin. The present invention is particularly preferably applied to fasteners for ornaments such as tie tacks, pin brooches, earrings, necklaces, etc., but fasteners for various articles of relatively small size other than ornaments.

Also applies. Background art

book

Conventionally, pin-type fasteners for body ornaments such as earrings have been provided with pin 1 having a circumferential groove 2 near the tip as shown in FIG. 1 (a) (not shown). In general, a structure is used in which the fastening member 3 of the pin fastener is inserted into a position where it engages with the circumferential groove 2 and fixed. Then, the pin 1 can be removed from the pin fastener by detaching the fastening member 3 from the circumferential groove 2 by an appropriate operation.

In particular, in recent pinning type fasteners, there are many structures in which the fastening member enters and leaves the circumferential groove of the pin using a spring material having an elastic deformation function. Since normal pin fasteners are small in size, it is reasonable to simplify the fastener structure with a pinning mechanism that uses spring material.

[Reference 1] JP 2 0 0 2-3 3 6 0 1 4

As a first prior art, in the earring fastener proposed in the above-mentioned document 1, a hole 6 is formed in the guide portion 5 which is the central portion of the substrate 4 as shown in FIG. 2 (a). Provided. A cylindrical guide piece 7 is fitted into the hole 6, and a pin is inserted through the through hole 8 of the guide piece 7. On the other hand, an elastic piece 9 with a guide groove 10 is formed around the substrate 4. The elastic piece 9 is gently bent toward the back side of the substrate 4 to form a loop portion 11. In other words, As shown in (b), the pin 12 is inserted from the guide part 5 side of the substrate 4, and the loop part 11 is bitten into the peripheral groove 13 to fasten the pin 12.

Next, as a second prior art, a pin fastener shown in cross-sectional views in FIGS. 3 (a) and (b) is also proposed. In this pin fastener 14, a pair of fastening members 16 made of an elastically deformable material is housed inside a force par 15 that is generally circular or elliptical. These fastening members 16 are configured substantially symmetrically about a central pin insertion portion 17 and have a pin fastening arm 18 and a holding arm 19 each having the shape shown in the figure.

In the pinned state, as shown in FIG. 3 (a), the holding arms 19 of both the fastening members 16 press the other fastening member 16 in the opposite direction, and as a result, a pair of pinning arms 1 8 is pressed in the direction of pin insertion part 1 7. Therefore, the pin (not shown) in the pin insertion part 17 is fastened by a pair of pinning arms 1 8.

When pulling out the pin from the pin fastener 1 4, push the button part 2 0 protruding from the fastening member 1 6 to the outside of the cover 1 5 toward the center. Then, as shown in FIG. 3 (b), the pair of pinning arms 18 are separated from the pins against the urging force of the holding arms 19 to release the pinned state.

However, in the first and second prior arts described above, the fastening member of the pin fastener (that is, the loop part 11 in the first prior art and the pin fastening arm 18 in the second prior art) is not connected to the pin. This is a structure in which it is brought into contact with the circumferential groove from the radial direction (right side direction). In such a structure, the pin input (the force required to insert the pin into the pin fastener) and the pin pulling force (the force required to pull out the pin without removing the fastening member) are basically The same strength. Therefore, if the pin 揷 input is set small in consideration of the ease of pinning operation, the pin pulling force is also reduced. As a result, for example, when the piercing is caught on the hair, the pin may come off even if the pinning operation is not performed. Therefore, it is less likely that the earrings will drop out or be lost without knowing it.

Next, in the first prior art described above, a very small cylindrical guide piece 7 is manufactured, and it is necessary to fit this into the hole 6 of the substrate 4. Furthermore, it is necessary to fix this fitting portion by means such as welding. In the second prior art described above, it is necessary to accurately manufacture a pair of pin fasteners 14 having a very small and complicated shape and to assemble them to the cap 15. Therefore, it is necessary to increase the production cost and the yarn cost. Disclosure of the invention

An object of the present invention is to provide a pinning type fastener that has a small pin insertion force but a large pin pulling force, and that can be easily released from a pinned state by a simple operation. . Another object of the present invention is to make the structure of such a fastener a simpole and reduce its manufacturing cost.

(First invention)

The first invention of the present application comprises a pin clamp and a pin provided with a circumferential groove in the vicinity of the tip, and the pin fastening member is inserted into the circumferential groove of the pin to fasten the pin. A fastener that releases from the circumferential groove and releases the pinned state,

The pin clamp is made of a single rectangular thin hook-shaped spring material that can be bent, and the center portion in the longitudinal direction of the spring material is bent into an acute or arcuate shape, thereby forming the top portion and its top portion. A triangular side surface formed of a pair of inclined portions on both sides is provided, and a pin retaining hole for inserting a pin is provided at the top portion, and a pin is formed from a peripheral portion in the longitudinal direction of the pin retaining hole. It is a fastener in which a pair of the fastening members of a length that bites into the circumferential groove of the pin inserted into the fastening hole is projected in the same direction as the inclined portion.

Next, embodiments of the present invention will be described with reference to the drawings. The technical scope of the present invention is not limited by the following examples.

Example 1

(Production process and configuration of Example 1)

Fastener 2 1 consists of pin 2 2 and pin 2 3.

FIG. 4 (c) shows a mold cage member 24 for producing the pin clamp 22. This template member 24 is formed by subjecting a rectangular thin plate-like panel material that can be bent and elastically deformed to punching or other appropriate processing. A central portion 25 (a portion surrounded by a broken line) of the template member 24 is a portion for forming a pinning hole. In the central part 25, by providing notches 26 in a certain shape A pair of fastening members 27 are formed which face along the longitudinal direction of the mold cage member 24 and gradually narrow toward the tip. A small space 28 is cut out between the tips of the pair of fastening members 2 7, which is calculated and calculated accurately. In other words, a pinning hole is formed in the central part 25, and a pair of fastening members 2 7 project from the peripheral edge in the longitudinal direction of the pinning hole toward the central part. The space 28 is left between the tips.

The central portion 25 of the template member 24 is bent into an arc shape as shown in FIG. 4 (a). At that time, it is preferable to fix the bent shape by heat treatment. The pair of fastening members 27 is not bent. Both ends in the longitudinal direction of the template member 24 may be folded along the broken line 29. A shallow groove-shaped cut may be provided in the portion indicated by the broken line 29 to facilitate this folding.

The pin clamp 22 formed in this way is made of a single rectangular thin plate spring material, and the central portion of this spring material is a top portion 30 bent into an arc shape, and on both sides of the top portion 30. Has a triangular side shape with a pair of slopes 3 1. The top part 30 bent into an arc shape has a shape in which a pair of fastening members 27 protrude from the peripheral edge part in the longitudinal direction of the pin fastening hole. Since the pair of fastening members 27 are not bent, they project in the same direction as the inclined portion. The pair of fastening members 2 7 protrudes to a length so as to bite into the peripheral groove 3 2 of the pin when the pin 2 3 is inserted into the pin fastening hole.

(Use state of Example 1)

The fastener 2 1 according to Example 1 is used as follows. That is, when pinning the fastener 2 1, the pin 2 3 is inserted into the pinning hole of the top portion 30 from the bottom side in the triangular shape of the pin 2 2. At that time, the pin 23 is inserted while elastically deforming the pair of retaining members 27 protruding from the pin retaining holes and pushing them outward. Since the pair of fastening members 27 protrudes in the same direction as the inclined portion 31, the pair of fastening members 27 does not show a strong resistance to the insertion of the pin described above. When the circumferential groove 2 3 a of the pin 2 3 reaches the protruding position of the retaining member 2 7, the retaining member 2 7 elastically returns to its original shape and enters the circumferential groove 2 3 a of the pin 2 3. Pinning is complete. When the fastening member 2 7 enters the peripheral groove 2 3 a of the pin 2 3, a light hammering sound is emitted, so that the completion of the pinning can be easily confirmed. For this reason, the fastener 21 can be securely pinned. In the case of the fastener 2 in the pinned state, the fastening member

2 Circumferential groove 2 with 7 protruding in the opposite direction to the direction in which pin 2 3 comes out 2

3 Since it bites into a, the pin 2 3 cannot be removed from the pin fastener 2 2 if left as it is. For this reason, even if the pinning 2 2 or the pin 2 3 is hooked on, for example, the hair or other members, the pinning state is maintained, and there is no problem such as loss due to falling off of the ornament.

To release the pinned state of the fastener 2 1, pinch each end of the pair of inclined portions 3 1 of the pin 2 2 with, for example, the thumb and forefinger, and (b) in Fig. 4 Apply a force in the direction of the arrow shown in (the direction of compression between the ends of the inclined part 31). By this operation, as shown in FIG. 4 (b), the top part 30 of the pin 22 2 is elastically deformed so as to bend more sharply.

This situation is illustrated in more detail in FIG. (A) in FIG. 8 shows the top 30 in the pinned state, and (b) in FIG. 8 shows the top 30 in releasing the pinned state. As shown in FIG. 8 (b), the pair of fastening members 27 are displaced in the direction of opening each other by causing elastic deformation so that the top 30 of the pin fastener 2 2 bends sharper. To do. Accordingly, the pair of retaining members 27 is separated from the peripheral groove 23a force of the pin 23. Therefore, pin 2 3 can be easily removed from pin 2 2.

Example 2

(Production process and configuration of Example 2)

The fastener 3 2 according to this embodiment includes a pin 3 3 and the same pin 2 3 as in the first embodiment. The pin clamp 33 is manufactured using a template member 34 shown in FIG. 5 (b). The mold member 3 4 is made of a material that can be bent and has elastic deformation ability.

The template member 34 is provided with a notch 2 6 in the central portion thereof in the same manner as the template member 24 described above, thereby forming a pair of fastening members 2 7 and a space 28. Only In the template member 34, extension portions 35 for forming a bottom side portion 37 to be described later are provided at both ends in the longitudinal direction. In the extended portion 35, a pin through hole 36 is formed in a portion immediately below the top portion 30 when the bottom portion 37 is formed. Since the pin through hole 36 is formed in an oval shape that is long in the left-right direction in the figure, the inserted pin 23 can be relatively moved in the left-right direction.

The center portion of the template member 34 in the longitudinal direction is bent into an arc shape as shown in FIG. 5 (a) to form a pair of inclined portions 31 with the top portion 30. Further, the extended portion 35 which is the end portion of the inclined portion 31 is bent along the broken line in FIG. 5B to form a pair of bottom portions 37 that overlap each other. These broken lines may be provided with shallow groove-like cuts to facilitate this folding. The pin through hole 36 is located immediately below the top portion 30 of the bottom side portion 37.

Further, the tips of the pair of bottom side portions 37 have lengths that do not reach the base of the other bottom side portion 37, respectively. Therefore, as shown in FIG. 6 (a), when the pin 3 of the fastener 3 2 is released, the top 30 of the pin fastener 3 3 is elastically deformed so as to bend more sharply. Hanarare.

As shown in FIG. 5 (b), an ear piece 38 is formed at one end of the extension 35. As shown in FIG. After the bottom portion 37 is formed as described above, the ear piece 38 is bent in the direction of the other bottom portion 37. The same applies to the ear pieces illustrated in the following embodiments, but the ear pieces 38 may be provided with shallow groove-shaped cuts for easy folding along the broken lines shown in the drawings. good. By bending the above-mentioned ear pieces 38, the bottom portions 37 of both are constrained to each other in a state where a relative sliding operation in the longitudinal direction is possible.

(Use state of Example 2)

The usage state of the fastener 3 2 according to the second embodiment is the same as that of the first embodiment except for the following points. That is, in the pinning of the fastener 3 2, the pin 2 3 is passed through the pin through hole 3 6 from the bottom side in the triangular shape of the pin fastener 3 3 and then inserted into the pinned hole of the top portion 30. Pinned pin 2 3 and pinned 3 3 Are constrained to move at two points: a pinning hole at the top 30 and a pin through hole 36 at the bottom 37. As a result, the pin 3 3 does not swing relative to the pin 2 3, so that the pinned ornament does not swing unstably.

Furthermore, since the bottom portions 37 of both sides are bound to each other by the ear pieces 38, the structural strength of the pin clamp 33 is high. In addition, since both the bottom side portions 37 can perform a relative sliding operation in the longitudinal direction, even if the ear pieces 38 are provided, the pinning state as described in the first embodiment is canceled. Pinning 3 3

FIG. 7 is a perspective view of the fastener 32 in the pinned state.

[Modification of Example 2]

In the second embodiment, a template member 39 shown in FIG. 6 (b) may be used. In this template member 39, the pair of retaining members 40 is not shaped to become gradually thinner toward the distal end than the aforementioned template members 24, 34, but the same width from the proximal end to the distal end.

Similar to the template member 24 according to the first embodiment, the template member 43 can be bent and is a rectangular thin plate spring material made of a material having an elastic deformation capability. It is formed by performing appropriate processing such as punching. A pin hole 4 5 is simply formed in the central portion 4 4 of the template member 4 3. At both ends in the longitudinal direction of the central portion 4 4, extension portions 3 5 similar to the template member 34 according to the embodiment 2 are provided, and pin through holes 3 6 are formed in these extension portions 3 5. is doing.

On the other hand, the folded pieces 46 are projected in the short direction from the left and right side portions of the pin fastening holes 45 in the central portion 44. Furthermore, from these folded pieces 4 6 the center A pair of fastening members 47 are provided so as to protrude into the pin fastening holes 45 when folded back on the portion 44. Between the tips of the pair of fastening members 47, a space 49 equivalent to the space 28 in the case of the template member 24 is set. Each of the folded pieces 4 6 is provided with an ear piece 48.

The center portion in the longitudinal direction of such a template member 43 is bent into an arc shape in the same manner as in the first embodiment to form a pair of inclined portions 31 with the top portion 30. Further, by bending the extended portion 35 which is the end of the inclined portion 31 along the broken line in FIG. 9, a pair of base portions 37 that overlap each other is formed. The extended portion 35 may be provided with a shallow groove-shaped cut for easy folding along the broken line shown in the figure. The pin through hole 36 is located immediately below the top part 30 in the bottom part 37. The tips of the pair of bottom portions 37 are not long enough to reach the base of the other bottom portion 37, respectively.

Further, the pair of folded pieces 46 are bent so as to overlap each other on the surface of the inclined portion 31 along the broken line shown in the figure. The folded piece 46 may be provided with a shallow groove-shaped cut for easy folding along the broken line shown in the figure. As a result of such folding forming, the pair of fastening members 47 projected from the pair of folded pieces 46 protrudes toward the center portion of the pin fastening hole 45. The above-mentioned ear pieces 4 8 are bent in the direction of the inclined portion 31 to be locked to the inclined portion 31, and the folded pieces 4 6 are brought into close contact with the inclined portion 31 by the ear pieces 48. .

(Use state of Example 3)

In the fastener 4 according to Example 3, there is a structural difference in that the fastening member 4 7 protrudes from the folded piece 46. However, the operation to pin the fastener 4 1 and the pinned state are released. This operation is the same as that in the first embodiment.

Further, as in the case of Example 2, the pin ² 3 and the pin 4 2 in the pinned state are two points, that is, the pin hole 4 5 at the top 30 and the pin through hole 3 6 at the bottom 3 7. Since the movements are restrained in each other, the pinned ornaments do not swing unstable.

[Modification of Example 3] Although not shown in the figure, as a modification of the third embodiment, as in the second embodiment, an ear piece provided on one of the bottom portions 37 is bent in the direction of the other bottom portion 37. Thus, it is also preferable that the bottom side portions 37 of both sides are restrained from each other in a state in which relative sliding motion in the longitudinal direction is possible.

Example 4

(Production process and configuration of Example 4)

As shown in FIG. 11 (a), the fastener 50 according to the present embodiment includes a pin 51 and the same pin 23 as in the first embodiment. The fastener 50 is preferably applied to a neckless, for example, and the pin clamp 51 and the pin 23 are respectively connected to the neckless chain 52.

The pin 51 is manufactured by using a mold member 53 shown in FIG. 11 (b). The template member 5 3, like the template collar member 24 according to the first embodiment, can be bent and is a rectangular thin plate spring material made of a material having elastic deformation ability. It is formed by performing appropriate processing such as punching. In the central portion 54 of the template member 53, a pair of fastening members 27 are formed with a space 28 in the middle by providing cuts 26 in a fixed shape.

An extension portion 35 similar to the template member 34 according to the second embodiment is provided at one end portion in the longitudinal direction of the central portion 54, and a pin through hole 36 is formed in the extension portion 35. On the other hand, at the other end in the longitudinal direction of the central portion 54, an extension portion 56 for forming a rising portion 55 described later is provided. Then, a pair of ear pieces 58 protrude from the distal end portion of the extension portion 56 via a planned bending portion 57 indicated by a broken line in the short direction.

In the fastener 50 according to the fourth embodiment, as in the second embodiment, the pin 2 3 and the pin 51 in the pinned state are the pin hole of the top portion 30 and the bottom portion 37. Because the movement is restrained at two points with the pin through hole 3 6, the pinned ornaments do not swing unstable.

Further, since the fastener 50 is formed in a thin shape, for example, when used as a necklace, since the swelling of the fastener hidden under the clothing is small, the appearance and appearance are good. In addition, the fastener 50 is stabilized by the presence of the rising portion 55. In addition, shelter member 59 surrounding the tip of pin 23 inserted into the pinning hole is formed, so the fastener 50 is inadvertently handled and the sharp tip of the pin pierces the wearer's finger or skin. Can be prevented.

The state of use of the fastener according to Example 6 is basically the same as in Examples 1 and 2.

In other words, when pinning the fastener, the pin 23 is inserted into the pinning hole 71 of the top portion 69 from the bottom side of the triangular shape of the panel member 67 in the pinning 66. At that time, the pin 23 is inserted while pushing the retaining member 77 projecting into the pin retaining hole 71 outward. Since the pair of fastening members 77 protrudes in the same direction as the inclined portion 70, they do not show a strong resistance to the insertion of the pin 23 described above. When the circumferential groove 2 3 a of the pin 2 3 reaches the protruding position of the retaining member 7 7, the retaining member 7 7 returns to the original position and enters the circumferential groove 2 3 a of the pin 2 3, Complete.

When the fastening member 7 7 enters the circumferential groove 2 3 a of the pin 2 3, a light impact sound is emitted, so that the completion of the pinning can be easily confirmed. For this reason, the fastener can be securely pinned. In the pinned state, the fastening member 7 7 is biting into the circumferential groove 2 3 a in a state protruding in the direction opposite to the direction in which the pin 2 3 is pulled out. Does not come out of pin 6 6. For this reason, even if the pin clamp 6 6 or the pin 23 3 is caught by, for example, hair or other members, the pin clamp state is maintained, and there is no inconvenience such as loss due to falling off of the ornament.

When it is desired to release the pinned state of the fastener, each end of the pair of inclined portions 70 of the panel member 6 7 is pinched with, for example, the thumb and the index finger, and the space between the ends of the inclined portion 70 is compressed. Apply force in the direction of By this operation, as shown in FIG. 14 (b), the top portion 69 of the panel member 67 is elastically deformed so as to bend more sharply. One pair of bases 7 3 Space left at the tip of 7 7 4 Force This inertial deformation is allowed. Due to this elastic deformation, when the space 74 is eliminated as shown in FIG. 14 (b), the pin 23 is passing through the hole formed by the pair of notches 75. It becomes. Due to such elastic deformation of the panel member 67, the pair of fastening members 77 are displaced in the direction of opening each other. Accordingly, the pair of retaining members 7 7 is detached from the circumferential groove 2 3 a of the pin 2 3. Therefore, the pins 2 6 can be easily removed from the pins 6 6. Further, in pinning the fastener, the pin 23 is allowed to pass through the space 74 from the bottom side in the triangular shape of the spring member 67 and then inserted into the pinning hole 7 1 of the top portion 69. The pin 2 3 and the pin 6 6 in the pinned state are restrained from moving at two points of the pin retaining hole 7 1 and the bottom 7 3 of the top 69. Therefore, the pin clamp 6 6 does not swing relative to the pin 23, so that the pinned ornament does not swing unstably. Industrial application fields
