Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an attachment device suitable for use in attaching, for example, leather, synthetic resin, metal watch bands, etc. to a stopper.

``Prior Art'' Conventionally, when attaching a watch band made of leather, synthetic resin, or metal to the wrist, for example, a pin with a buckle (or buckle) is engaged with a hole formed in the leather band. In use, the length of one band piece is adjusted by fitting the tip of one band piece into the buckle and pulling it back. The operation involved fitting the holes in the attached rods and fitting the free straps to the tips of the loose band pieces.

However, due to these operations, the surface of the band is likely to be rubbed and deformed when it is fitted with the buckle, and even if the band is made of high-quality leather, it may be damaged by the buckle. In addition, the connection between the buckle and the band is done by fitting the attached rod and the attached hole, and the fixation in the length direction of the band is unstable. There was also the problem that the appearance of the building was damaged by the prominence of the objects.

``Problems that the invention seeks to solve'' Therefore, as a result of intensive research to solve these problems, the applicant and others have developed a method that replaces the buckle-applied fastener with a conventional mainly metal watch band. If you connect a leather band, etc. to the applied two-fold stopper or three-fold stopper, the band itself will not be damaged, and the excellent advantages of these fasteners can be obtained. I came to the idea that it could be done.

However, these types of two-fold and three-fold stoppers are designed to connect metal bands, so in order to connect a leather band or the like to these fasteners, for example, It is necessary to create a pin insertion hole etc. by folding back the end of the band piece, and as a result, the thickness of this part becomes thicker, making it impossible to connect it to the fastener, or deteriorating the aesthetic appearance. Problems such as

The present invention effectively solves these problems, and has a simple structure that allows leather bands, synthetic resin bands, and metal bands to be easily turned into two-fold or three-fold fixing brackets. It is an object of the present invention to provide an attachment device for a watch band that can be worn.

``Means for Solving the Problems'' In order to achieve the above object, the present invention provides a method for connecting a band piece between a bottom plate that is hinged to a fold-in piece of a stopper and supports the back side of the band piece, and the bottom plate. A cover plate attached in a clamping manner, a support shaft integrally protruding from the inner surface of the cover plate and penetrating the band piece and having a screw hole at the tip, and a support shaft that is inserted into the screw hole of the support shaft through the bottom plate. It consists of a mounting bolt that is screwed together.

"Embodiment" An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, what is indicated by the symbol A is a band piece of a watch band made of leather or synthetic resin, and what is indicated by the symbol B is a stopper that connects the pair of band pieces A to each other. In the illustrated example, the stopper B includes a connecting bottom plate 1 that contacts the skin, first and second fold-in pieces 2 that are hinged to both ends of the connecting bottom plate 1 and overlapped on the connecting bottom plate 1. 3, and a locking means 4 for locking the folding pieces 2, 3 to the connecting bottom plate 1 when the folding pieces 2, 3 are folded over the connecting bottom plate 1, and the locking means 4
is a pair of locking pieces 5 formed by cutting and raising a part of a plate material on the first and second folding pieces 2 and 3;
and a through hole 6 that engages with the locking piece 5.

Reference numeral 10 indicates a watch band attachment device according to the present invention, which includes a bottom plate 11 that is hinged to the fold-in pieces 2 and 3 of the stopper B and supports the back side of the band piece A; A cover plate 12 is attached to sandwich the band piece A between the cover plate 12, a supporting shaft 13 integrally protrudes from the inner surface of the cover plate 12, passing through the band piece A, and having a threaded hole at the tip. A mounting bolt 14 is screwed into the screw hole of the support shaft 13 through the bottom plate 11.
It is composed of.

The free end of the bottom plate 11 bends inward (upward in FIG. 2) to form a biting part 15 for the band piece A, and a pair of bolt holes 16 are formed on the bottom plate 11. has been done.

On the other hand, a portion of the cover plate 12 is curved downward (downward in FIG. 2) so as to surround the end of the band piece A, and its tip 12a is further bent inward to form the tip of the fold-in piece 2. (hinge part). Width dimension of this cover plate 12
D ₁ is set longer than the width dimension D ₂ of the bottom plate 11 . Note that side plates 17 may be provided on both sides of the cover plate 12 to cover the sides. On the other hand, the length L ₁ of the cover plate 12 is set longer than the length L ₂ of the bottom plate 11, as shown in FIG. It's starting to stand out.

A support shaft 13 protruding from the inner surface of this cover plate 12
This prevents the band piece A from coming off, and is inserted into a bolt hole 18 formed in the band piece A.

In addition, in the figure, what is indicated by the reference numeral 20 is a spacer with a bolt hole 20a disposed between the band piece A and the bottom plate 11.

Next, the operation of the mounting device of the present invention constructed as described above will be explained.

To connect the band piece A to the fastener B using the attachment device 10, as shown in FIG. Attach the end of band piece A to the
The mounting bolt 14 may be screwed onto the support shaft 13 via the bottom plate 11 by pressing it against the bottom plate 11 which is hinged to the tip (free end) of the support shaft 13 .

This assembly is a simple operation of simply inserting each member (band piece I, cover plate 12, etc.) and connecting them with bolts, and does not require any special technology or equipment for the assembly. By forming a bolt hole 18 in the metal watch band made of leather, synthetic resin, or metal, it is possible to
Since it can be easily connected to a folding stopper, etc., it improves the applicability of leather, synthetic resin, or metal watch bands to two-fold or three-fold fixings. Can be done. Also,
In this manner, when the mounting device 10 is assembled, the tip 12a of the cover plate 12 comes into elastic contact with the hinge portions of the folding pieces 2 and 3 and pushes the band piece A, thereby preventing the band piece A from loosening. It has the advantage of being effective.

Also, attach a watch to one side of the band,
When wearing this watch on your wrist, for example, fold it over the connecting bottom plate 1 using the first folding piece 2, and insert the locking piece 5 of this folding piece 2 into the through hole 6. and engage the edge of the hole, and at the same time, insert the second folding piece 3 into the first folding piece 2.
The locking piece 5 may be engaged with the through hole 6 by folding it in the same manner as above.

Also, to remove the watch band from your wrist, etc.
Using the cover plate 12 as a mark, the cover plate 12 may be pulled up to release the engagement between the locking piece 5 and the through hole 6.

In the above embodiment, the watchband stopper B was shown as a two-fold stopper in which the two folding pieces 2 and 3 were hingedly connected to both ends of the connecting bottom plate 1. The fasteners are not limited to this, and may have other structures.

"Effects of the Invention" As explained above, the present invention is a watch band attachment device that connects a pair of watch band pieces to a stopper that connects them to each other. The mounting device is integrated into a bottom plate that is hinged to the folded piece of the stopper and supports the back side of the band piece, a cover plate that is attached to the bottom plate in a manner to sandwich the band piece, and an inner surface of the cover plate. It consists of a support shaft that protrudes through the band piece and has a threaded hole at its tip, and a mounting bolt that is screwed into the threaded hole of this support shaft through the bottom plate, so it can be made of leather or synthetic resin. Made by
A metal watch band can be easily connected to a two-fold stopper or a three-fold stopper to improve its applicability, and the watch band will not be damaged during use. You can get the great benefits of
