Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band-shaped accessory worn on the body such as a wrist watch, a bracelet, a necklace, etc., and more particularly to a pin for connecting a piece constituting a band.

[0002]

2. Description of the Related Art A belt-shaped accessory including a plurality of members rotatably connected to each other is widely used. For example,
In the bracelet, a main body portion on which pyroxene or the like is arranged and a band for winding the main body portion around a wrist are rotatably connected to each other. Further, in the wristwatch, the main body that houses the movement, that is, the case, and the band for winding the case around the wrist are rotatably connected to each other. Also,
Nakadome and the band are also rotatably connected to each other.
Known clasps used for the band-shaped accessory include clasps that can enlarge and reduce the circumference of the band, and clasps that can connect and separate one band from the other band.

FIG. 27 is a cut-away plan view showing a part of a wristwatch band. A metal piece 1 has a pair of projections 3 formed on both sides opposite to the center projection 2 on one side in the longitudinal direction of the band.
And adjacent pieces are rotatably connected by a connecting pin 4. More specifically, a connecting hole 5 is formed in the central convex portion 2, a connecting hole 6 having a smaller diameter than the hole 5 is formed in the convex portion 3, and a split pipe 8 having a slit 7 in the longitudinal direction is inserted into the hole 5. Has been done. By inserting the convex portion 2 of one piece into the concave portion 9 between the both convex portions 3 of the other piece and inserting the pin 4 into the split pipe 8, the pipe expands and presses against the inner wall of the hole 5, Is fixed to the pipe 8, and the pin and the convex portion 3 are rotatably connected.

Usually, the relative rotation between one piece and the other piece about the connecting pin as an axis is limited to a range of a predetermined angle. That is, as shown in FIGS. 28A and 28B, the piece 1
When the other piece 1b is rotated with respect to a, when the angle formed by both pieces reaches a specific angle, the lower portion 2b of the convex portion 2 of the piece 1a and the lower portion 9a of the concave portion 9 of the piece 1b come into contact with each other. ,
Relative rotation of both pieces is blocked beyond this angle.

[0005]

However, when a wristwatch is used, an external force for further rotating the piece may be applied to the piece from the state shown in FIGS. 28 (a) and 28 (b). . Then, as shown in FIGS. 29A and 29B, the one connecting hole 5 and the other connecting hole 6 are separated from each other in the longitudinal direction and the thickness direction of the band. Therefore, connecting pin 4
Shear force is applied to. When the bending of the connecting pin bent by this shearing force exceeds its elastic limit, FIG.
As shown in (a), the connecting pin is plastically deformed into a bent state. When the connecting pin bends in this way, the pieces cannot rotate and the band cannot be worn on the body. Such a problem often occurs not only between two pieces but also between two members rotatably connected to each other.

For example, when the piece is rotated with respect to the case, when the angle between the two reaches a specific angle, the case and the piece come into contact with each other, and the relative rotation of the both is prevented. When the piece is further rotated from this position, the pin connecting the case and the piece is bent similarly. Similarly, when the piece is rotated with respect to Nakadome, when the angle between the two reaches a specific angle, Nakame and the piece come into contact with each other, and the relative rotation between the two is blocked. If the piece is further rotated from this position, the pin connecting Nakadome and the piece will be bent.

The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a belt-shaped accessory including at least two members rotatably connected to each other. It is an object of the present invention to provide a structure in which the connecting pin connecting both members is prevented from bending due to the relative rotation of the members.

[0008]

In order to achieve this object, a belt-shaped accessory according to a first aspect of the invention according to claim 1 is a connecting pin for connecting one member to another member adjacent to one member. A space formed in at least one of the one member and the other member and allowing the elastic bending of the connecting pin. With this configuration, even if an excessive external force is applied to the connecting pin due to the relative rotation of the one member and the other member, the connecting pin is allowed to elastically deform in the space, so that the connecting pin does not bend. .

Here, it is preferable that the space portion is formed in at least one of the opening portion of the one connecting hole and the opening portion of the other connecting hole facing each other. Further, the space portion is communicated with the connection hole, along the axial direction of the connection pin,
It can be a recess recessed toward the inside of the member.
Further, it is preferable that the space portion has a portion that is wider than the connecting hole along the radial direction of the connecting hole. Further, it is preferable that the space portion is a cylindrical recess that is concentric with the connecting hole and has an inner diameter larger than the inner diameter of the connecting hole. This facilitates drilling of the connecting hole and the space.

When it is necessary to make the space portion large in the radial direction of the connecting hole, an opening portion may be provided to connect the space portion and the outside of the member. In this case, the opening is
It is preferable to open the back surface of the member. As a result, the opening is not visually recognized, so that the appearance of the belt-shaped accessory is not impaired.
Further, the opening may be opened in a gap between one member and the other member. Even in this case, the opening is not easily visible. Of course, in one of the connecting holes, both the opening facing the other connecting hole and the opening of the other connecting hole facing the one connecting hole,
The space portions may be formed to face each other. As a result, large elastic deformation of the connecting pin is allowed, and the spatial allowance of the connecting pin in the axial direction is further increased. Therefore, the connecting pin is less likely to bend. Further, it is preferable to use a connecting pin made of a highly elastic metal because the connecting pin is less likely to bend.

In order to achieve the above-mentioned object, the belt-shaped accessory of the second invention according to claim 12 is one connecting hole provided in one member and the other connecting hole provided in the other member. And a coupling pin made of an elastic metal, which is inserted into and, and the opening of one coupling hole and the opening of the other coupling hole which face each other in cooperation with the relative rotation of the one member and the other member. And an expansion means for expanding the space therebetween. With this configuration, when one member and the other member are rotated relative to each other, the space between the opening portion of the one connecting hole and the opening portion of the other connecting hole is expanded by the expanding means, and the space is expanded. Since the elastic deformation of the connecting pin made of elastic metal is allowed inside, the connecting pin does not bend. This expansion means is formed on each member,
Including that the connecting pin penetrates an inclined surface inclined with respect to the axis of the connecting pin. Further, when the connecting pin made of elastic metal is used, it is preferable to provide a retaining means for preventing the connecting pin from being pulled out from the connecting hole of the piece. That is, if the connecting pin repeats elastic bending, it may move in the connecting hole along the axial direction, and the end of the connecting pin may
The piece may protrude from the connecting hole of the piece and the connecting pin may come off the piece. As this retaining means,
Means for interfering the both ends of the connecting pin and the piece with each other so that the connecting pin does not come out of the piece is preferable. By adopting such means, it is possible to prevent the connecting pin from being pulled out while allowing elastic deformation of the connecting pin. The one member and the other member in the present invention may be a piece and a piece, a main body portion and a piece, or a clasp and a piece. Here, the main body may be a wristwatch case.

[0012]

1 is a cutaway plan view showing a part of a first embodiment in which the present invention is applied to a wristwatch band, FIG.
(A) and (b) are plan views and side views when one piece is rotated to one side, and FIGS. 3 (a) and (b) are plan view and side surfaces when one piece is rotated to the other. 4 and 5 are perspective views of the piece. As shown in FIG. 4, the piece 10 has a protrusion 11 at the center on one side in the longitudinal direction of the band and a pair of protrusions 12 at both ends on the other side, and a recess 13 is formed between them. ing. A connecting pin 14 (FIG. 1) is inserted into the convex portion 11 and a connecting hole 15 having a diameter that allows the piece to rotate is formed.
On the other hand, the convex portion 12 is formed with a connecting hole 16 having the same diameter as the hole 15 on the outer side, and a cylindrical space portion 17 having a larger diameter than the hole 16 on the inner side.
Are formed.

The connecting pin 14 is made of a metal having an extremely high elasticity. Then, as shown in FIG. 1, the connecting pin 14 is inserted into the hole 16, the space 17 and the hole 15 of the adjacent pieces 10a and 10b, and both ends of the pin are expanded into hemispheres by a riveting punch to form a rivet head 14a. Use as a retainer. That is, since the connecting pin 14 has a high elasticity, there is a possibility that the connecting pin 14 may escape if it is repeatedly bent and extended in the connecting holes 15 and 16. Therefore, it is preferable to provide a retaining means for preventing the escape.

Next, the operation will be described. Figure 2 (a)
When the piece 10b is rotated counterclockwise as shown in FIG. 3 (b), the lower edge of the convex portion 11 of the piece 10a and the bottom wall of the concave portion 13 of the piece 10b come into contact with each other, and FIG. When the piece 10b is rotated in the clockwise direction as shown in (), the corners of the protrusions 12 come into contact with the corners of the piece 10a. Then, when the bridge is excessively rotated, the connecting pin 14 having superelasticity is shown in FIG.
Then, the space 17 is elastically deformed downward in the plane of FIG.
In (a), it elastically deforms above the paper surface. Since it is elastically deformed, the piece can be returned to its original state, and the pin returns to its original linear shape. Therefore, the size of the space 17 is set so as to allow deformation in the elastic region, that is, the diameter and axial length of the cylindrical space are selected accordingly. As described above, according to the present invention, the connecting pin is returned to the original state without being plastically deformed, so that the wearability of the belt-shaped accessory can be secured.

The connecting pin 14 is made of, for example, stainless steel,
It may be made of a known metal that has been conventionally used for the connecting pin, such as titanium or a titanium alloy. The space portion 17 allows the deformation of the connecting pin 14 within the elastic region regardless of the material of the connecting pin 14. However, it is preferable that the connecting pin 14 is made of a material having an ultrahigh elasticity because it is more difficult to bend. A shape memory alloy can be used as the metal having ultrahigh elasticity. Specifically, Ni-Ti, Ni-Ti-Cu, Ni-Ti
-Fe, Ni-Ti-Nb, Ni-Ti-Zr, Ni-

The material of the connecting pin can be selected from alloys such as Si-Cr-Ni.

FIG. 5 is a perspective view showing a modification of the first embodiment. The space 17 shown in FIG. 4 cannot be processed without using a special tool. This modification solves the problem. In this example, the space portion 20 is opened downward by the parallel inner wall. Such a shape can be easily formed, for example, by milling or pressing. FIG. 6 is a perspective view showing a second embodiment of the present invention, and FIG. 7 is a cut-away plan view showing an elastically deformed connecting pin. In this embodiment, the pair of spaces 21 are formed in the central convex portion 23 of the piece 22. That is, the connecting hole 24 is formed in the central portion of the convex portion 23, and the concentric and large-diameter space portions 21 are formed on both sides thereof. On the other hand, a connecting hole 26 is formed in each of the other pair of convex portions 25. Connecting pin 2
7 is elastically deformed as shown in FIG. The space portion which is open outward in the lateral direction as described above can be processed extremely easily.

FIG. 8 is a perspective view showing a modified example. In this example, the space portion 27 is further formed to be deviated laterally in the band longitudinal direction, and the opening portion 27a is formed therein. That is, when a large-diameter space portion is required, it may not fit in the convex portion 28. In such a case, if the opening 27a is formed on the upper surface of the convex portion 28, the appearance of the band is deteriorated. Therefore, the connecting hole 29 is slightly offset outward in the longitudinal direction so that the opening is formed outward.
