Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for fixing a watch band and a clasp.

[Conventional technology]

Conventionally, various types have been used to fix one clasp to the other, such as a tri-fold type, a hook type, and a hook type on a separate block. As for fixing the clasp, there were two types: one in which the band was held vertically by rotating a cam, and another in which the band was tightened with a small screw.

[Problem that the invention attempts to solve]

However, with the type in which the band is held vertically by the rotation of the cam, the space required for the cam makes the entire clasp thick, and with the type in which the band is secured by tightening it with a small screw, it is difficult to carry the band while carrying it. There is a problem that serious quality problems such as screw loosening and rusting of screws are likely to occur. I was getting used to the internet, and couldn't find anything that was thin, luxurious, and had stable fixation quality. The present invention is an attempt to solve these problems, and its purpose is to create a product that is thin, has a luxurious feel, is resistant to changes in material over the long term, and has excellent fixation quality for the band and clasp. The objective is to provide a fixing structure for the watch band and clasp.

[Means for solving problems]

The fixing structure of the watch band and clasp of this invention is
A band having an adjustment groove on the back side, a bottom part formed with a protrusion that engages with the adjustment groove of the band, and a side that has a hole into which both ends of a spring bar are inserted and is raised upward from both ends of the bottom part. and a base frame comprising an upper part formed inward from the upper end of the side part in parallel with the bottom part, a band pressing plate installed in a gap between the surface of the band and the upper part of the base frame, and the upper part. The present invention is characterized by comprising a spring bar disposed at the end of the band holding plate in the mounting direction, for positioning the band holding plate, and mounted in holes drilled in both sides of the base frame.

〔Example〕

The present invention will be explained below using figures. As mentioned above, since the present invention can be applied to all types of clasps, the fixing part between the clasp and the clasp will be omitted, and the explanation will be limited to the fixing part between the band and the clasp.

Fig. 1, Fig. 2 A to D, and Fig. 3 A to C show an embodiment of the present invention. Fig. 1 is a sectional view, and Fig. 2 and Fig. 3 are perspective views of each part. It is a diagram. 1
1 is a base frame, 12 is a band, 13 is a band holding plate,
14 is a spring bar. As for the fixing method, base frame 1
The optimum position of the adjustment groove 12a provided in the band 12 is engaged with the protrusion 11a formed on the bottom 11c of the band 12 at right angles to the longitudinal direction of the band 12, and the band surface and both sides of the base frame 11 are engaged. Part 11d
The band pressing plate 1 is inserted inward from the upper end so as to fill the gap between the bottom part 11c and the upper part 11e formed parallel to the bottom part 11c.
3 from the side, and the spring rod 14 is pushed into the hole 11b provided in the side part 11d raised above both ends of the bottom part 11c of the base frame 11, thereby completing the fixing. In other words, before the band holding plate 13 is attached, there is a gap between the top and bottom of the base frame and the band, so the band can slide freely over the positioning protrusion, but when the band holding plate 13 is attached, the band slides freely. Since there is no gap for vertical movement, the band and base frame are fixed. Further, the spring rod 14 is used to prevent the band holding plate from sliding naturally and come off, and also serves to stabilize the fixing quality by holding the band between the base frame and the base frame. Figures 3A and B are Figure 2B
The band holding plate 13 shown in Fig. 1 is shaped to have spring properties, and it absorbs variations in the band holding plate attachment gap due to variations in the thickness of parts, and provides stable fixing quality. Furthermore, FIG. 3C shows another embodiment of the base frame shown in FIG. 2A, and the upper surface of the band of the base frame is not covered all around as in FIG. 2A. It is a characteristic. The shape shown in FIG. 2A is difficult to press-form, but the shape shown in FIG. 3C can be processed only by press-forming. Further, this opening can also be used as a space for a part of the clasp on the other side to enter, which is effective in reducing the thickness.
Next, one embodiment of the present invention will be explained using FIGS. 4 and 5. FIG. 4 is a sectional view, and FIGS. 5A and 5B are perspective views of each component. The basic configuration and mechanism are the same as those shown in Figs. 1, 2, and 3. In this case, the band holding plate 43 has a folded shape as shown in the figure, and its spring property is intended to stabilize the fixing quality. Therefore, it is thicker than in Fig. 1 by the folded thickness, but as shown in Figs. Since the area around the spring bar can be used effectively, a part of the other clasp can be hung or attached to the spring bar. The spring bar 44 is characterized in that it can perform two functions: fixing the band holding plate 43 and fixing the other clasp. The base frame 41 is shown in Figure 3C.
It can also be made into a shape that can be pressed. FIGS. 6 and 7 also show an embodiment of the present invention. FIG. 6 is a sectional view, and FIGS. 7A and 7B are perspective views of each component. The basic configuration is the same as in FIGS. 4 and 5, but the feature in this case is that the spring rod 64 for positioning the band fixing member 63 is first inserted into the band holding plate 63, and then the band is integrated into the band. The band is pressed down by sliding it into the gap between the base frame and the base frame. In this case,
The spring bar is no longer visible from the outside, resulting in a cleaner appearance.

Next, another embodiment of the present invention will be explained with reference to FIGS. 8 and 9. Figure 8 is a sectional view, Figure 9 A.
B shows a perspective view of each component. In each of the above explanations, the fuller slide is possible without cutting the band, but in this case, the feature is that the band is interrupted at the clasp by cutting or removing the frame. It is. The installation method and the like are exactly the same as those described above. The band holding plate has a shape as shown in Figure 9A, but by providing a barb in part as shown in Figure 9B, a space is created around the spring rod, and the spring rod can be attached to the other clasp. It can also be used as a fixing member. Further, as in each of the above-mentioned embodiments, a spring portion may be formed on the band holding plate,
By bending and forming the band, it is possible to stabilize the fixing quality of the band, and as shown in FIG. 6, the spring bar can be covered to give a cleaner appearance. In the case of this structure, by effectively utilizing the part of the clasp where the band does not fit and providing the function of fixing the other clasp there, the clasp as a whole can be made to have a very thin and unified shape. In other words,
This has the advantage that it can be made thinner than the previous example by the thickness of the band.

[Effect of the invention] The watch band and clasp fixing structure according to the invention includes a band having an adjustment groove on the back surface, a bottom portion of the band with a protrusion that engages with the adjustment groove, and a spring bar at both ends of the band. a base frame comprising a side portion having a hole into which the bottom portion is inserted and rising upward from both ends of the bottom portion; and an upper portion formed inward from the upper end of the side portion in parallel with the bottom portion; a surface of the band and the base frame; A band holding plate attached to the gap between the upper part of the frame and a band holding plate provided at an end of the upper part in the mounting direction of the band holding plate and used to position the band holding plate and provided with openings on both sides of the base frame. Since it is composed of a spring bar that is attached to a hole,
The total thickness of the upper part 11e of 1, the band 12, and the band holding plate can be set as the sum of the thicknesses of the upper part 11e of 1, the band 12, and the band holding plate, so it is thin and b.
The band is fixed to the clasp by a band holding plate that is installed in the gap between the top of the base frame and the surface of the band and positioned by a spring bar, and the cam mechanism and screws rotate. Unlike the fastening method, there is no part that loosens or rotates, so the band will not come off the clasp unless the base frame itself or the spring bar deforms, and there will be no problems such as loosening or coming off while carrying. However, it is very good, and has the remarkable effect of being able to provide a fixing structure for the watch band and clasp, with only three components: the base frame, band holding plate, and spring bar.
