Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a clasp length adjusting device for a wristwatch band.

[0002]

[Prior Art]

 Conventionally, as a structure for adjusting the length of the clasp of the clasp of the wristwatch band, there are structures shown in FIG. 5 (Japanese Utility Model Laid-Open No. 51-19865) and FIG. 6 (Japanese Utility Model Laid-Open No. 51-18168).

In the structure of the clasp length adjusting device for the clasp of the prior art described above, the band-shaped hole 12 and the band-shaped hole recess 13 are provided on both side surfaces of the upper box 11, and the spring rod 14 that engages with the band-shaped hole recess 13 is provided. Both ends of the slide plate portion 15 are engaged with each other.

In the above-described conventional length adjusting method, the watch band is attached to the arm, the amount of adjustment according to the thickness of the arm is visually set, and then the watch band is removed from the arm. The spring rod 14 or the slide plate 15 is pressed toward the upper box, and both ends of the spring rod 14 or the slide plate 15 engaged with the band hole concave portion 13 of the upper box 11 are moved toward the band hole 12. It became movable, and the length was adjusted by moving the above-mentioned amount measured visually.

[Problems to be solved by the device]

 The conventional watch band adjustment structure is a structure in which it is attached to the arm once when adjusting, a guideline for the amount of adjustment is set by eye measurement, and the amount of adjustment is adjusted after detaching from the arm. The ambiguous setting of the adjustment amount may cause the adjustment amount to be improper and the adjustment amount to be measured again. Furthermore, when the watch band is folded into the upper box, the band always presses against the spring rod or slide plate, and force is applied in the direction in which the engagement between the band hole and the spring rod or slide plate is released. There was a sufficient risk of disengagement when working. An object of the present invention is to solve the above-mentioned problems and provide a wrist watch band structure having a good wearing feeling, which fits to the thickness of the arm while being worn on the arm, and there is no danger of easy disengagement even after fitting. Especially.

[0006]

[Means for Solving the Problems]

 The present invention is a foldable upper box attached to the tip of one band, band holes provided on both sides of the above box, band hole recesses provided in the middle of the band holes, and the other band. A clasp consisting of a slide attached to the tip of the slide, two push plates in the slide that are pressed outward by springs, and a locking part that prevents the push plate from popping out. In the structure, usually, the protrusion of the push plate inserted into the band hole is held in the band hole recess, and by pushing the push plate, the protrusion is disengaged from the band hole recess, The clasp of a wrist watch band, wherein the slide is adapted to be slidable in the upper box.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of the clasp of the present invention, FIG. 2 is a side view of the upper box of the clasp of the present invention, FIG. 3 is a perspective view showing a coupling state of the band and the slide of the present invention, and FIG. FIG. 3 is a partially cutaway plan view showing the internal structure of the slide of FIG.

The upper box 1 has a band-shaped hole 2 symmetrically formed on its side surface, and a plurality of band-shaped hole recesses 3 formed in the band-shaped hole 2 at regular intervals. The slide 4 has in it two push plates 5 which are pushed outward by springs 6. The push plate 5 is prevented from coming off by a locking portion 4a of the slide 4 and a locking portion 5b provided on the push plate 5. Further, the push plate 5 has a projection 5a which engages with the band-shaped hole recess 3 of the upper box 1, and when the push plate 5 is pushed, the engagement is released. The band 7 is joined to the slide portion 4.

Next, a procedure for assembling the clasp according to the present invention will be described. First, the push plate 5 of the slide 4 in which the push plate 5 and the spring 6 are incorporated is pushed into the slide 4 joined to the band body 7, and the upper box 1 is inserted in the longitudinal direction. Since the upper box 1 has the band-shaped hole 2 and the band-shaped hole recess 3, the push plate 5 is engaged with the band-shaped hole 2 by moving the slide 4 in the longitudinal direction. At this time, the force of the spring 6 causes the push plate 4 to pop out of the band-shaped hole recess 3 and the assembly is completed.

Next, the operation of the present invention will be described. By pushing the push plate 5 protruding from the band-shaped hole 2 of the upper box 1 from both sides with fingers, the projection 5a provided on the push plate 5 is disengaged from the band-shaped hole recess 3 of the upper box 1 and moved in the longitudinal direction of the band. It will be possible. By pushing and moving the push plate 5 to an arbitrary position and releasing the finger, the projection 5a provided on the push plate 5 pops out due to the force of the spring 6, and the projection 5a is re-engaged with the band-shaped hole concave portion 3 of the upper box 1 and is lengthened. Directional movement is fixed. The push plate 5 has a structure in which the locking portion 4a provided on the slide 4 and the locking portion 5b of the slide plate 5 are engaged with each other so that the push plate 5 does not come off.

As described above, according to the present invention, since the push plate 5 can be moved while pushing the finger on the wrist while the watch band is attached to the wrist, the push plate 5 can be moved on the spot without the need to remove it from the wrist for adjusting the length. It can be adjusted to fit the thickness of the arm, and the slide 4 does not exert any force to disengage the upper box 1 and the band 7, so you can freely and safely adjust it while wearing it on your arm. It is a wristwatch band structure.
