Abstract

PURPOSE:To obtain a high-reliability, thin, and small-sized timepiece case by inserting a plate-shaped member into a horizontal groove provided under a glass edge which is inserted into a collar part provided on a body and bringing this plate-shaped member into contact the lower face of the collar part to fix the glass edge to the body. CONSTITUTION:A glass edge 11 is inserted to a body 13 from above, and thereafter, the space in the diametral direction between the glass edge 11 and the body 13 is used to insert a fixing member 15 to a groove part 11a of the glass edge from the side of a rear cover, and the glass edge is fixed in the axial direction by this insertion, and the fixing member 15 is fixed to a body inside face 13a by welding, caulking, or the like. In this case, assembling is made easier if inserting parts 15a-15c of the fixing member are bent to use their elasticity. Since an adhesive or the like is not used at all, this fixing is permanent. Consequently, the reliability of quality is high, and this timepiece case is used without anxiety for a long time.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for fixing the glass edge of a watch case to a body, and is particularly effective in fixing a non-circular glass edge to a non-circular body. .

An object of the present invention is to obtain a reliable thin and small watch case by securely fixing the glass edge of the watch case to the case, and to obtain a watch case with a variety of designs.

A conventional watch case is shown as a typical example in FIG. 1, in which a glass 2 is integrally fixed to a non-circular glass edge 1 by press-fitting, caulking, etc., and a lower part 1a of the glass edge 1 is attached to an upper part 3a of a body 3. A dowel 4a is fixed with adhesive and provided on the outer periphery of the non-circular back cover 4 in a groove 3C provided on the inner lower part 5b of the body.
It was designed to be fixed by spraying and engaging.

In this structure, the glass edge 1 and the body 3 are fixed with adhesive, but the adhesive deteriorates over time due to changes in humidity and temperature, resulting in the fatal possibility of peeling off. Due to these drawbacks, the fixation between the glass rim and the body was incomplete.

The present invention is intended to eliminate the above-mentioned drawbacks, and relates to a structure in which a glass edge, in which the glass is integrally fixed by press-fitting, caulking, etc., is fixed to the body without using an adhesive.

This makes it possible to obtain a watch case that is highly reliable and small in size, as well as a watch case with a wide variety of designs.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. so as to be engaged with the groove 11a at the bottom of the body 13 and fixed to the inner surface 13a (inner surface) of the collar of the body 13 by welding, caulking, etc.
This is the fixed part side where the arranged planar shape is approximately plate-like.

The fixing part 15 is made by bending and forming a plate material as shown in FIG.
The part a is the part that engages with the groove 11a of the glass edge 11, and the parts 15 (115e, i5f) are the parts that are fixed to the inner surface 13a of the barrel 15 in FIG. 2 by welding and caulking.

An example of how to attach the glass edge 11 in the embodiment shown in FIG.
The fixing member 15 is inserted into the groove 11a of the glass edge using the radial gap to fix the glass edge in the axial direction, and then the fixing member 15 is fixed to the inner surface of the body 13a by welding, caulking, etc. At that time, as shown in FIG.
If 5&, 15b, and 15c are bent to take advantage of their elasticity, assembly becomes easier.

In this case, since no adhesive or the like is used, this fixation is permanent. Therefore, it is reliable in terms of quality and can be used with confidence over a long period of time.

FIG. 4 shows an embodiment in which a simple glass edge 21 is fixed to the body 23, whereas FIG. 2 shows an embodiment using a glass edge in which the glass is integrally fixed. It is something that The principle of this fixing structure is exactly the same as that shown in FIG. 25 is a plate-like member. In this case as well, since no adhesive is used, this fixation is permanent.

Therefore, it is highly reliable in terms of quality and can be used with confidence for a long period of time. 22 is glass.

FIG. 5 also shows the glass edge 31 and body 33 of the embodiment shown in FIG.
A gasket 37 is provided between the two to ensure a tight seal between the two, and the entire watch case is made of a wood structure. This completely protects the internal clock mechanism. 35 is a plate-like member.

By adopting the structure as described above, the present invention has an extremely reliable fixing structure and advantageous design compared to conventional watch cases in non-circular shaped cases where it is difficult to attach the watch glass to the body. This makes it possible to obtain a watch case that is extremely effective and has a wide range of uses.

Claims (1)

[Claims] In a structure in which a glass rim in which non-circular glass is integrally fixed is fixed to a non-circular shaped body, the glass rim is inserted upward into the brim provided above the body, and the lower part of the inserted glass rim is placed. A watch case characterized in that a plate-like member is inserted into the provided horizontal groove and the plate-like member comes into contact with the lower surface of the buckle part, thereby fixing the glass glass green to the case.
