Description

[Detailed Description of the Invention] The present invention relates to the framework structure of a timepiece.

Wooden frame clocks have been around for a long time, but they have problems with moisture resistance, and dimensional stability is poor due to moisture absorption, etc., which often results in loosening of the front cover. Also, plastic frames are available with wood grain patterns or veneer applied to the surface to give them a wood-like feel, but they have the disadvantage that it is difficult to create a wooden structure where the ends are joined together.

The present invention aims to solve the above-mentioned drawbacks, and one embodiment thereof will be described below.

FIGS. 1 and 2 show an example of a wooden structure of a front frame 1 of a wall clock, in which a plurality of rod-shaped frame members 2 are joined at their end faces to form a framework. Each frame material 2
To explain the structure with reference to FIG. 3, it consists of a hollow outer covering material 3 integrally extruded from plastic, a decorative board 4 such as a veneer laminated to the outer surface of the outer covering material 3, and a square material 5 serving as a core material. It has a composite structure consisting of The outer cover material 3 consists of a central hollow frame 6 with a rectangular cross section, an inner hollow frame 7 and an outer hollow frame 8 located inside and outside of the central hollow frame 6.
has been inserted. In this example, on the rear surface of the central hollow frame 6, a groove 9 is formed in the longitudinal direction in order to cope with dimensional errors in the square timber 5, and the square timber 5 can be seen from there. In addition, the rear surface of the inner hollow frame 7 is
This serves as a holding surface 11 of the front cover 10, and in this example, this holding surface 11 (the rear surface of the inner hollow frame 7) is separated from the side surface of the central hollow frame 6, thereby reducing the elastic force of the inner hollow frame 7. It's increasing. However, it is also possible to make the holding surface 11 integrally connected to the side surface of the center middle frame 6, and in this case also, the inner hollow frame 7 has a certain degree of elasticity. The frame members 2 having such a structure are abutted at their cut ends, and the square members 5 exposed from the end faces are bonded and fixed together with an adhesive to form a frame as shown in FIGS. 1 and 2. A mounting plate 12 is fixed to the front frame 1 constructed in this manner through wood screws 13, and the wood screws 13 pass through the rear groove 9 of the central hollow frame 6 and are screwed into the square timber 5. be. The receiver 14 provided on the mounting plate 12 and the holding surface 10 of the inner hollow frame 7
The outer periphery of the front glass 10 is elastically held between the two. Note that 15 is a clock dial.

According to the above structure, due to the presence of the square timber 5, a wooden structure as shown in FIG. Since it is covered with the hollow frame 6, dimensional deviations due to moisture absorption etc. are less likely to occur. Also, the front cover 1 is attached to the back of the inner hollow frame 7.
Since the outer periphery of the front cover 10 can be pushed elastically, there is no play in holding the front cover 10. Furthermore, even when the cross-sectional shape of the outer covering material 3 is changed in various ways, the square material 5 can be used in common, which is economical, and the mounting plate 12 can be easily mounted using wood screws 13.

Claims (1)

[Claims for Utility Model Registration] (1) The front frame of the watch is framed by a plurality of rod-shaped frame members, each of which consists of a rectangular central hollow frame and inner hollow frames located inside and outside the rectangular central hollow frame. and an outer hollow frame are integrally formed of plastic, a decorative board is attached to the outer surface of the outer cover, and a wooden square piece is inserted into the center hollow frame. Each of the frame members is constructed by joining and fixing the square pieces together at their end faces with an adhesive, and connecting the front face with a part of the mounting plate fixed to the back of the front frame and the back surface of the inner hollow frame. A frame structure for a watch, characterized in that the outer periphery of the cover is clamped. (2) The framework structure of a timepiece according to claim 1 of the utility model registration, characterized in that the back surface of the inner hollow frame is separated from the side surface of the central hollow frame.
