Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a connecting structure of a wooden frame watch case and a glass plate.

(Prior Art) FIG. 4 shows a conventional joint structure of a wooden frame watch case and a glass plate. A small-diameter opening 4 is provided in the front of the wooden frame case 2, and a large-diameter opening 8 for mounting the glass plate 6 is provided in the rear. The glass retainer 10 is formed of a synthetic resin member having an L-shaped cross section. The front edge 7 of the glass plate 6 is brought into contact with the step surface 12 of the wooden frame case 2, and the glass presser 10 is firmly connected to the wooden frame case 2 with the nails 14, so that the glass plate 6 is made into the wooden frame case. Is bound to two.

(Problems to be solved by the invention) In the conventional glass pressing structure shown in FIG. 4, when the pressing force in the direction of the glass plate 6 by the pressing member 10 is excessive when the nail 14 is driven, the glass plate 6 is It cracks and nails again
If the driving position of 14 is shifted downward in FIG. 4, the glass plate 6 will rattle. Therefore, the work of driving the nail 14 was troublesome. Further, if the thickness direction of the glass plate 6 is not pressed down tightly, the glass plate 6 will rattle also in the plane direction, and especially when the design pattern is printed on the glass plate 6, the print deviation is conspicuous. There was a problem that the value decreased.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to provide a glass holding structure which facilitates the glass holding work.

(Means for Solving the Problems) In order to achieve the above object, according to the present invention, a timepiece wooden frame case having a small diameter opening in the front and a large diameter opening in the rear, and the small diameter opening. A glass plate that is larger and smaller than the large-diameter opening, one end of which is fixed to the inner surface of the large-diameter opening, and a curved portion that is formed by bending from the inner surface to the center of the case. The movable end of the curved portion has a pressing portion that presses the side edge of the glass plate, and the stepped surface of the wooden frame case, the curved portion, and the elastic glass pressing portion that holds the glass plate by the pressing portion, It is characterized by being composed of.

(Embodiment) An embodiment according to the present invention is shown in FIGS.
The same members as those in the conventional example of FIG. 4 are designated by the same reference numerals, and detailed description thereof will be omitted.

An elastic glass retainer 16 made of an elastic member is fixed to the large diameter opening 8. As shown in FIG. 2, the elastic glass retainer 16 has a wedge-shaped connecting arm 18 having an uneven surface formed inside and the connecting arm 18
And a glass holding portion 22 provided at the movable end of the bending portion 20. The elastic glass retainer 16 is fixed to the wooden frame case 2 by fitting the connecting arm 18 into the fixing hole 24 provided in the large-diameter opening 8.

When connecting the glass plate 6 to the wooden frame case 2, the glass plate 6 is inserted from the large-diameter opening 8 side, and the side end of the glass plate 6 is pressed against the curved portion 20 of the elastic glass retainer 16 to be pushed in. Since the length of the glass holding portion 22 is set to be substantially the same as the thickness of the glass plate 6, when the side edge of the glass plate 6 gets over the curved portion 20 and is sandwiched by the glass holding portion 22, the glass holding portion 22 is held. The front edge is in contact with the step surface 12 of the wooden frame case 2, and the glass plate 6 is pressed from both sides in a well-balanced manner by the elastic glass retainers, so that the center of the glass plate 6 and the center of the small-diameter opening 4 are substantially aligned. .

FIG. 3 shows another elastic glass retainer 26 according to the present invention. The elastic glass retainer 26 is provided with a hole 28 that is firmly fixed to the wooden frame case 2 with a wooden screw or the like.

(Effect of the Invention) According to the present invention, since the elastic glass retainer itself is connected to the wooden frame case before the glass plate is attached, the glass plate is not broken by the impact when the glass retainer is attached unlike the conventional case.
The glass plate can be easily joined by pushing it in from the large-diameter opening of the wooden frame case, and both ends of the glass plate are pressed in good balance by elastic glass retainers, so the center of the glass plate is the small-diameter opening of the wooden frame case. It is installed almost in the center of. As a result, when the glass plate is provided with the design pattern, the pattern shift or the like does not occur at all.
