Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a structure for mounting a dial to a wooden frame.

[Prior Art] Conventionally, as a method of attaching a dial to a wooden frame, first, the dial and the dial receiver are positioned, and then the two are attached by double-sided adhesive tape or the like, and then the letter is attached. A method is known in which a board support is attached to a wooden frame with screws or the like. As a method of positioning the dial and the dial receiver, there is a method of visually aligning the convex portion provided on the outer periphery of the dial and the concave portion provided on the outer periphery of the dial receiver. As another method for positioning the dial and dial support, a method is known in which a bent tongue is provided on a part of the outer periphery of the dial and the tongue is fitted into a hole provided in the dial support. ing.

[Problems to be Solved] In the first conventional method, it is difficult to accurately align the position of the dial. Further, in the second conventional method, a hole for positioning or a part of the tongue is visible, which is not preferable for a luxury timepiece. Further, the dial plate having the tongue piece for positioning has a problem that the cost is increased because the spacer is used when the component is transported in order to prevent the occurrence of scratches.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a dial plate mounting structure for a wooden frame which allows accurate and easy alignment of the dial plate with the support plate without damaging the appearance.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the feature of the mounting structure of the dial to the wooden frame of the present invention is that the wooden frame and the metal supporting plate located on the back surface of the wooden frame are provided. ,
It consists of a dial sandwiched between the wooden frame and the support plate, and a fixing screw for fastening the support plate to the wooden frame.At the fastening position of the fixing screw, the dial has a long hole and the support plate has a through hole. , Each of which is formed in a positional relationship facing each other, and a bent portion having a width equal to or slightly smaller than the width of the long hole is formed on the peripheral edge of the through hole of the support plate toward the wooden frame side. When the fixing screw is fastened, the tip of the bent portion penetrates the long hole and bites into the wooden frame.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings. Figure 1,
In FIG. 2, a metal support plate 2 is provided on the back surface of the wooden frame 1.
Is located.

In FIG. 2, a dial 3 is arranged on the front surface of the support plate 2, and the dial 3 is sandwiched between the wooden frame 1 and the support plate 2. An elongated hole 3a is formed in the lower portion of the dial plate 3. A through hole 2b is formed in the lower portion of the support plate 2, and a tongue-shaped bent portion 2a is formed by bending toward the wooden frame side at the peripheral portion of the through hole and the bent portion 2a is formed. The height is larger than the thickness of the dial plate 3.

The long hole 3a and the through hole 2b are formed so as to face each other, and the width W (shown in FIG. 3) of the bent portion 2a is equal to the width w (shown in FIG. 3) of the long hole 3a. The width is formed to be slightly smaller than that, and the bent portion 2a can penetrate the elongated hole 3a.

Fastening of the support plate 2 to the wooden frame 1 is performed by screwing a fixing screw 4 to the wooden frame 1 from a back surface of the support plate 2 through a dial plate 3 arranged on the front surface of the support plate 2. . When the fixing screw 4 is fastened to the lower portion of the support plate 2, the fixing screw 4 is screwed to the wooden frame 1 through the through hole 2b and the long hole 3a from the rear surface of the bent portion 2a, and is bent. The tip portion 2c of the portion 2a penetrates the elongated hole 3a and bites into the wooden frame 1.

Therefore, the alignment between the dial plate 3 and the support plate 2 is accurate and easy. The area occupied by the through hole 2b and the bent portion 2a is formed small, and the brim portion 4a formed on the head of the fixing screw 4 can cover the area occupied by the through hole 2b and the bent portion 2a. The bent portion 2a is not visible even from the back side of the wooden frame 1. Therefore, the appearance is not spoiled.

In FIG. 1, a mechanical mounting plate 5 is provided on the back surface of the support plate 2.
Is provided, and the timepiece mechanical body 6 is attached to the central portion of the mechanical body mounting plate 5. On the upper portion of the back surface of the support plate 2, there is provided a hook metal 7 for hooking a hook screw (not shown) or the like planted on a wall surface or the like. The hook metal 7 is swingably attached to the machine body mounting plate 5, and can be taken out as shown in a chain line when the clock is hooked. A hook recess 2d is provided on the upper rear surface of the support plate 2. The hooking recessed portion 2d can be locked to a locking screw or the like instead of the locking metal fitting 7 when it is desired to make the locking metal fitting 7 invisible from the front of the wooden frame 1.

[Effect] As described in detail above, according to the present invention, at the fastening position of the fixing screw, the long hole is formed in the dial plate and the through hole is formed in the support plate so as to face each other, and the support is provided. Since a bent portion having a width equal to or slightly smaller than the width of the long hole was formed by bending toward the wooden frame side in the peripheral portion of the through hole of the plate, positioning and fixing of the support plate to the wooden frame can be performed. By using the bent portion for ensuring the accuracy, the dial plate and the support plate can be aligned accurately. Further, in the fastening state of the fixing screw, the tip of the bent portion penetrates the elongated hole and bites into the wooden frame, so that there is a great effect that the appearance is not damaged.
