Abstract

(57) [Abstract] [Purpose] The present invention aims to provide a new slide-fit type clasp that can be easily inserted and removed and that can be securely fitted around the wrist. [Structure] In the present invention, a slide plate connected to one end of a band can be freely inserted into and removed from the inner surface of the upper box of a three-folded middle clasp formed by folding and unfolding an upper box and a middle plate and a lower plate. , A spring stopper is attached to the back surface of the slide plate, and one-way locking teeth are juxtaposed on the upper surface of the middle plate. When the band is attached around the wrist, the folding of the middle clasp and the slide plate are performed. Is a slide-fit type clasp, characterized in that the band is fitted around the wrist by pushing and holding with the band.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This device is a slide-fit type clasp, specifically, the band can be easily inserted and removed around the wrist by widening the band, and the band can be easily inserted and removed around the wrist by attaching the slide plate with the band. This is a slide-fit type clasp that can be fitted securely.

[0002]

[Prior art]

 Japanese Utility Model Publication No. Sho 54-37656 proposed by the applicant of the present application discloses a three-fold metal fitting in which an auxiliary metal fitting 2 is fitted to an upper box 1, wherein the size of a band wheel is adjusted by adjusting the access to the auxiliary metal fitting 2. It is described that it did.

[0003]

[Problems to be solved by the invention]

 However, since the overhang plate 7 of the above publication is merely an attempt to fit the band ring when worn around the wrist by adjusting the access, the spread of the band ring when deployed is still insufficient, and the overhang plate 7 is fitted around the wrist. There is a problem that it is often difficult to pull out and remove, and there is a problem that it is not possible to fine-tune the band and fit it around the wrist.

[0004]

[Means for Solving the Problems]

 In the present invention, when the clasp is deployed, the slide plate becomes free due to the release of the hook and slides to the full limit to slide and widen the band hoop, so it is easy to insert and remove around the wrist, This problem was solved by pressing the slide plate with the band when folded so that it could be fitted around the wrist without fail.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A three-folded clasp 5 formed by folding an upper box 1, a middle plate 2 and a lower plate 3 and connecting them with pins 4 is formed. Then, a slide plate 6 which can be freely moved in and out is fitted to the inner surface of the upper box 1, and the mounting end of the half band 7 a is fixed to the outer end of the slide plate 6.

An inverted V-shaped spring stopper 9 facing the band 7 is attached to the base rear surface of the slide plate 6. In addition, one-way locking teeth 10 are juxtaposed on the upper surface of the middle plate 2. In other words, the slide plate 6 can be pushed and slid from the band mounting side of the upper box 1 to the non-band 7a mounting side, but the spring pawl 9 hits the pawl 10 in the opposite direction so as not to slide.

A mounting end of the other half band 7 b is fixed to the open end of the lower plate 3. In addition. 12a is a hook for hooking between the lower plate 3 and the middle plate 2, 12b is a hook hole, 13a and 13b are folded-down lower plates 3 and the middle plate 2 and further lower edges 1a and 1a of the upper box 1. The hook is a hook that hooks on the hook.

When the upper box 1, the middle plate 2, and the lower plate 3 of the middle clasp 5 are unfolded, the slide plate 6 becomes free by being latched and unfolded, and as shown in FIG. In order to spread the buckle, it can be fitted around the wrist very easily, and then the clasp 5 is folded as shown in FIG. 3 and the slide plate 6 is further pushed in as shown in FIG. The slide plate 6 is pushed with one end of the band 7a until the band ring fits around the wrist, where the spring stopper 9 comes into contact with the one-way pawl 10 and is hooked.

When pulling out from around the wrist, the upper box 1 or lower of the clasp 5 is deployed. The band is widened by the spread of the slide plate 6, which becomes free when the locking of the spring retaining claw 9 and the one-way pawl 10 is released, so that the band can be easily removed from around the wrist without difficulty. Reference numeral 6a denotes a stopper that contacts the folded end 1b of the upper box 1 in order to prevent the slide plate 6 from being pulled out.

[0010]

[Effect of the invention]

 As described above, according to the present invention, it is possible to securely fit the band ring around the wrist by fitting the slide plate to the inner surface of the upper case of the middle clasp, and pushing and locking the slide plate after mounting around the wrist. There is an effect that it can be done.

[0011] When the clasp is deployed, the slide plate becomes free and slides widely to make the band ring even larger, so that an effect of facilitating fitting and removing around the wrist is achieved.
