Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention concerns a push-type clasp for leather bands and urethane bands.

[0002]

[Prior art]

 This type of push-type Nakadome is disclosed in Japanese Utility Model Publication No. 3-35130 previously registered by the present applicant. The publication describes that a push button protruding from one side of the upper box and a band stab stop box consisting of a stab stop projection and an opening / closing lid are provided on an extension of the clasp connected to the upper box. .

[0003]

[Problems to be solved by the invention]

 However, this publication has a problem in that the push button for pushing protrudes from the upper box, so that it is unexpectedly pushed against another object and the clasp expands, and the structure is complicated and the manufacturing cost is reduced. There was a problem that it was not possible and the design lacked simplicity.

[0004]

[Means for Solving the Problems]

 According to the present invention, a notch is provided on the side wall of the upper box, a spring-tensioned push portion is faced to the notch, a two-folded clasp is connected to the upper box, and the lower plate of the clasp is slightly bent. It has a reinforced structure and is formed in a thin shape that easily fits around the wrist, and in addition to a hook for hooking on and off the opening / closing hole of the push part on the middle of the lower plate, one end of a leather band and a urethane band. An adjust mechanism for adjusting the band length, consisting of a through hole to be inserted through the back and a parallel stop hole of the band to select and stab the band, is provided, and the push part is suddenly pushed and the clasp is pressed. In addition to eliminating deployment, the structure was simplified to solve the above problems.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, description will be made with reference to the drawings.

A part of the top plate 2 and a part of the side wall 3 of the upper box 1 are cut out to form a cutout part 4 for operation, and a part of a push part 5 which is spring-fitted to the cutout part 4 faces. An opening / closing stop hole 6 is provided on the lower surface in the middle of the back surface of the push portion 5 when the push portion 5 is pressed and closed by spring pressure when the push portion 5 is released. Reference numeral 7 denotes an upper plate that is pin-connected to one side of the upper box 1 and 8 denotes a lower plate (rail).

The lower plate 8 has a reinforced structure that bends into a V-shape that is shallow when viewed from the side. The lower plate 8 is made thin so as to easily fit around the wrist of the wearer. And a through hole 11 through which one end of the leather band and urethane band 10 can be freely inserted and removed from the open end side, and two stab stoppers 12 provided on the back surface. An adjustment mechanism for adjusting the length of the band 10 is provided. Reference numeral 13 is a parallel stop hole provided in the band 10.

[0008] One end of the leather band or urethane band 10 passes through the through-hole 11 from the bent end of the lower plate 8 with its length adjusted, and is attached to the lower surface of the lower plate 8. The other end of the band 10 is inserted into the end of the upper box 1 with a watch case (not shown) interposed therebetween and the pin 13 is fixedly connected thereto.

When folded, the two-fold type clasp consisting of the upper box 1, the upper plate 7 and the lower plate 8 folds the band loop when folded, and the opening and closing stop hole against the spring 9 against the spring pressure. When the push part 5 is pushed, the opening / closing stop hole 6 is opened and the hook 9 is released, so that the middle clasp is expanded and the band ring is expanded.

[0010]

[Effect of the invention]

 As described above, according to the present invention, since the push portion is accommodated in the cutout portion of the upper box, there is an effect that the possibility that the clasp is suddenly developed against another object is eliminated. Since the lower plate of the clasp has a reinforced structure that bends slightly, it has the effect of being able to be formed in a thin shape that fits easily around the wrist. In addition, one end of the band can be easily adjusted in length by the adjustment mechanism using the bottom of the through hole in the lower plate, which has the effect of preventing the band from folding and the effect of simplifying the adjustment mechanism. .

In addition, since the structure of the push-type middle clasp is simplified, the production cost is reduced and the design is improved.
