Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an upright device that can be used for table clocks, photo frames, and the like.

[Prior Art] Conventionally, this type of upright device is rotatably formed by fitting the shaft of the stand into a hole in a bearing plate that protrudes rearward from a frame, and the stand is rotated by an appropriate degree determining means. It is constructed so that the opening angle can be determined (Utility Model Application No. 51-6967).

[Problem that the invention aims to solve] However, because of this configuration, if a strong external force is applied to the stand, stress may concentrate on a part of the bearing plate, causing cracks or damage. . Furthermore, since the bearing portion is exposed to the outside, there are disadvantages such as unsightliness.

Therefore, an object of the present invention is to provide an upright device that will not be damaged even if stress is concentrated on a portion of the bearing plate.

[Means for Solving the Problems] The present invention is characterized in that the rear end surface of the bearing pedestal protruding rearward from the frame body closely faces the inner surface of the back cover, and a bearing groove is formed in the rear end surface of this bearing pedestal. is provided, and the shaft of the stand is configured to be bearing between this bearing groove and the inner surface of the back cover.

[Function] As a result, even if a strong external force is applied to the stand,
The stress is dispersed in the bearing pedestal and back cover that surround the shaft of the stand, and stress concentration does not occur, so damage to the bearing part can be prevented. Also, since the bearing part is located inside the back cover, it eliminates the unsightly appearance of it being exposed to the outside.

[Example] An example in which the present invention is applied to a portable watch will be described with reference to the drawings.

A clock movement 1 is fixed to a mounting plate 3 which is fixed to a frame 2. A dial plate 4 is attached to the front surface of the mounting plate 3, and a front cover 5 is fitted to the frame body 2. The frame body 2 is fitted into the outer circumferential frame 6, and the entire body is connected integrally by screwing the back cover 7 to the mounting plate 3 with screws 8.

Bearing plates 9, 9 are integrally provided rearwardly protruding from the back side of both sides of the frame 2 as shown in the second and fourth figures, and the rear end surfaces of these bearing plates are connected to the inner surface of the back cover 7. close to. The rear end surface of the bearing stand 9 is provided with U-shaped bearing grooves 9a, 9a.

As shown in Figure 7, the back cover 7 has a hole 7a into which the watch movement 1 is fitted, and U-shaped notches 7b, 7b are formed oppositely at both left and right ends of this hole. be.

The shape of the stand 10 is approximately semi-circular as shown in the first and fifth figures, and the shape of the stand 10 is approximately semi-circular as shown in the first and fifth figures.
It is located around the outer circumference of the lower half of the back. At both ends of the stand 10, bearing parts 10a, 10a penetrate into the interior through cutouts 7b, 7b of the back cover 7, as shown in the figure. The shafts 10b, 10b protrude along the inner surface of the back cover and are located in the bearing groove 9a of the bearing stand 9.
For this reason, the shaft 10b is supported by the bearing groove 9a and the inner surface 7c of the back cover 7 facing the bearing groove 9a, as shown in the second and third figures.

Triangular adjustment protrusions 10c protrude from both ends of the stand 10, and as shown by the chain line stand 10' in FIG. The angle is determined in degrees.

Therefore, in order to assemble the upright device of the present invention, first bend the tip of the semicircular arc-shaped stand 10 slightly inward, and connect the shafts 10b, 10b to the notches 7 of the back cover 7.
b, 7b. This allows stand 10
The bearing portions 10a, 10a pass through the notches 7b, 7b, and the shafts 10b, 10b protrude along the inner surface of the back cover 7.

Then, when the watch movement 1 is fitted into the hole 7a of the back cover 7 and fixed to the mounting plate 3 with the screws 8..., the shafts 10b and 10b are inserted into the bearing groove 9a of the bearing stand 9.
The inner surface 7c of the back cover is supported between this bearing groove and the inner surface 7c of the back cover facing the bearing groove. stand 10
As shown in the first and third figures, the tip surface of the shaft 10b is
In addition to contacting the inner surface of the frame 2, the bearing portion 10a
Since its inner surface is in contact with the outer circumferential surface of the timepiece movement 1, it can no longer bend inward, preventing it from falling off and providing an appropriate slip torque.

The stand 10 is swung around the shaft 10b, and at the position of the stand 10' indicated by the chain line in FIG. Able to stand up stably.

[Effects of the invention] As described above, according to the invention, the shaft of the stand is supported inside the back cover between the bearing groove of the bearing stand protruding from the frame and the inner surface of the back cover. Stress does not concentrate and damage to the bearing part does not occur. Also, since the bearing part is not exposed to the outside, it is not unsightly. Furthermore, the structure is simple and assembly is easy.
