いう設計上の問題もあつた。 FIG. 1 shows a partially cutaway side view of a conventional large watch of this type. In this clock, a back plate 4 attached to the back opening of a cylindrical rear frame 3 is fastened to an anchor bolt 2 embedded in a wall 1 with a hexagonal nut 5, and the rear frame 3 is fixed to the wall 1. A wide diameter portion 6a formed at the rear end of a cylindrical front frame 6 having a small depth is fitted onto the front end of the frame 3 via a rubber packing 7. The front frame 6 is screwed onto the rear frame 3 by a screw 8 at the upper part of the rear end so as to be able to rotate upwardly, and the mechanical body 9 of the watch, the dial 10, the front glass plate 11, etc. are attached thereto. are doing. By the way, each of the above-mentioned members is assembled and attached to the front frame 6 in the following steps. That is, the rear part of the front end flange 6b of the front frame 6 is filled with a sealant such as a rubber seal 12 or putty, and the front glass plate 11 is placed so that the front edge of the front edge is in contact with the rear end of the flange 6b, and then a cylindrical endpaper is placed. Feed 1
3 to the rear peripheral edge of the front glass plate 11. Thereafter, a peripheral wall 1 was formed around the periphery of the dial 10 on the disk to which the machine body 9, hour hand 14, minute hand 15, etc. were attached.
6 is brought into contact with the inner circumferential wall surface of the rear end of the front frame 6, and the bolts inserted through holes drilled in the outer circumference of the front frame 6 are inserted into the circumferential wall 16.
The dial plate 10 is fixed to the front frame 6 by tightening it into a screw hole 17 formed with a counter sink or the like. Incidentally, a plurality of screw holes 17 are required for fixing the dial 10 in order to stably fix the dial 10, but the number of screw holes 17 to be installed varies depending on the size of the watch. For watches with a diameter of about 400φ, four locations are required, and for watches over 600φ, six or more locations are required for strength. And front frame 6 and dial 1
0, it is necessary to match the hole provided in the front frame 6 with the screw hole 17 provided in the peripheral wall 16 of the dial 10 shown in FIG. In this case, it was difficult to achieve accuracy in the pitch between the fastening parts and the dimension from the front end of the front frame 6 to the fastening part, making assembly very difficult. In this case, the holes in the front frame 6 may be formed into elongated holes to absorb dimensional errors, but if installed outdoors, new parts must be added for waterproofing, which increases the number of assembly steps. There is no particular benefit due to the cost increase due to etc.
Moreover, since the above-mentioned screw fastening is determined by the printing of characters on the dial plate, the holes in the front frame 6 and the screw holes 17 in the peripheral wall 16 of the dial plate 10 are drilled in consideration of this. There was also a design problem in that the installation location had to be determined.

針１４、分針１５の駆動軸である。 The present invention will be explained below with reference to examples. 3 to 6 are diagrams showing an embodiment of the present invention,
In order to have the same function as a conventional endpaper, the dial 10 of this embodiment is formed by bending the outer periphery so as to slightly open the diameter forward to form a peripheral wall 16, and further extending the front end of this peripheral wall 16 outward. It is bent to The front side of this outwardly bent piece 18 is connected to the flange 6b of the front frame 6.
This is for pressing against the peripheral rear surface of the front glass plate 11 whose peripheral front surface is placed against the rear end of the front glass plate 11. 19 in the diagram
4 is a holding metal fitting, and this holding metal fitting 19 is formed by bending a metal plate to have a substantially U-shaped cross section. In FIG. A long elongated hole 20 is bored in the hole. And the front piece 1 of this presser metal fitting 19
9b is for pressing against the rear surface of the outwardly bent piece 18 of the dial 10, and the rear piece 19c is for holding during assembly. Note that the rear frame 3 is fixed to the wall surface by fixing the back plate 4 to the anchor bolt 2 with the hexagonal nut 5.
The figure is similar to the conventional example. Further, reference numeral 21 in the figure is a drive shaft for the hour hand 14 and minute hand 15.

螺着するのである。 When fixing the dial 10 and the front glass plate 11 to the front frame 6, first, the peripheral edge of the front glass plate 11 is fitted into the rubber gasket 12 provided at the rear of the flange 6b of the front frame 6, and then the main body 9,
The dial 10 with the hour hand 14 and minute hand 15 attached is fitted into the front frame 6 from the rear opening of the front frame 6, and the outwardly bent piece 18 of the dial 10 is folded into the front glass plate as shown in FIG. 11 through the rubber gasket 12. Next, the front piece 19b is attached to the outer bent piece 18 of the dial 10 while holding the rear piece 19c by aligning the presser metal fitting 19 with the screw hole 22 previously provided in the appropriate position on the peripheral wall of the front frame 6. The screws 23 inserted into the screw holes 22 from the outside of the front frame 6 are inserted into the elongated holes 20 of the presser metal fitting 19, and the hexagonal nuts 24 and The presser metal fitting 19 is temporarily fixed to the front frame 6 by screwing them together.
Next, the screw 23 is tightened while pushing the rear piece 19c of the presser metal fitting 19 forward. In this way, the outer bent piece 18 of the dial 10 and the front glass plate 11 are clamped to the front frame 6 by the flange 6b of the front frame 6 and the presser metal fittings 19 at several locations, respectively. The front frame 6 with the dial 10 fixed thereto fits the front end of the rear frame 3 into the wide diameter part 6a at the rear end, and is screwed onto the rear frame 3 with screws 8 so that it can be opened and closed freely. That's what I do.

This x dimension is equal to the dimension C between the rear surface of the outer bent piece 18 in contact with the rubber packing 12 and the front end of the front frame 6, and the elongated hole 20 shown in FIG.
The center of the semicircular part on the front end side and the front piece 1 of the presser metal fitting 19
If the relationship between the dimension Aa between the front end of 9b and the dimension b between the center of the semicircular portion on the rear end side of the elongated hole 20 and the front end of the front piece 19b of the presser fitting 19 is a+c<x<a+b. good.

るのである。 9 to 11 show another embodiment of the present invention, in which the rear piece 1 of the presser fitting 19 is
9c' is bent to be inclined with respect to the front piece 19b, and a long hole 20' is bored parallel to this inclined rear piece 19c'. Then, the distance between the center of the hexagonal nut 24 (shown in Figure 10) and the apex of the outer shape using the dimension C between the longitudinal center line of the elongated hole 20' and the inner surface of the inclined rear piece 19c'. It is set smaller than dimension A of , and larger than dimension B between the center and the side. However, screw 23
and the hexagonal nut 24 to attach the presser metal fitting 19 to the front frame 6.
When the hexagonal nut 24 is tightened as shown in FIG. 1, the apex of its outer shape abuts against the inner surface of the inclined rear piece 19' of the presser metal fitting 19 as shown in FIG. 9, and its rotation is restricted. become. That is, the inclined rear piece 19c' of the presser metal fitting 19 functions to prevent the hexagonal nut 24 from rotating.

Therefore, the misalignment of the printing of characters etc. on the dial plate can be corrected. This can be easily corrected by rotating the dial, so the fixing position can be set freely.Furthermore, there is no need to provide a screw hole for fixing on the dial, which reduces the number of man-hours required to manufacture the dial. When drilling a screw hole in a frame, it is possible to have a wide tolerance range for the accuracy of the position of the screw hole, making processing very easy, reducing costs and simplifying assembly and manufacturing. has. It also has the advantage that the U-shaped rear piece of the presser metal fitting allows the holding metal fitting to be held during work, resulting in good workability.
