Description

[Detailed Description of the Invention] The present invention relates to a stand device that can tilt the front surface of a table clock, frame, etc. to make it easier to see.

Conventionally, when tilting a table clock, etc., a stand is attached to support it, a hole is made at the lower end of the leg of this stand, this is set as the center of rotation, and a screw, etc. is inserted into this hole to form the frame of the table clock. The position of the inclination angle is determined by tightening or fixing with screws and nuts to stabilize the slip torque.

However, with such a configuration, as the angle of inclination from the vertical plane increases, the center of gravity of the table clock, etc. becomes farther from the center of rotation, resulting in a larger rotational moment. It became.

Furthermore, if an attempt was made to support the device even at a large inclination angle, the device would have to be constructed with a stronger support mechanism, resulting in an oversized device, and it would also be difficult to adjust the slip torque after assembly.

The present invention eliminates the above-mentioned drawbacks by providing a swing center shaft on the lower edge of a watch, etc., and installing a long leaf spring on the leg of the stand opposite to this, increasing or decreasing the pressing force of the leaf spring against the shaft. By being adjustable, the stand provides a strong holding force that can withstand any angle of inclination.

The present invention will be explained with reference to the drawings.

Reference numeral 1 denotes a watch, in which a front frame 2 and a rear frame 3 house a watch mechanical body 4.

A stepped portion 5a is formed on the outer periphery of the back surface of the rear frame 3, and a frame-shaped stand 5 is fitted into this stepped portion.

At the center of the lower edge 3b of the rear frame 3, a mounting portion 7 for the swing center shaft 6 is formed in a layer over almost the entire lower side of the watch.

A swing center portion 8 protruding toward the mounting portion 7 is formed on the edge 5a of the stand 5 facing the lower edge 3b of the rear frame.

The swinging center part 8 has openings 8a and 8b on the surfaces facing the side plates 7a and 7b of the mounting part 7, and the center shaft 6 passes through the openings 8a and 8b to open the swinging center part 8. Penetrating.

A plate spring 9 made of stainless steel or the like is housed in the swinging center 8 and is brought into contact with the central shaft 6.

This leaf spring corresponds approximately to the length of the swing center portion 8, and has two U-shaped bent portions 10a and 10b formed in the middle, and the back surface of the bent portion is used for slip torque adjustment. The springs lla and llb press the leaf spring 9 in the direction of pressing the central shaft 6.

The screws 11a and 11b pass through the trap section 12 provided at the center of the stand 5.

13 is the back plate of the stand 5, and screws 11a, 1
Holes 13a and 13b are formed at positions opposite to 1b, and can be moved forward and backward by turning screws from the outside.

14 is a protrusion provided on the inner surface of the rear frame 3, and is a projection provided on the inner surface of the rear frame 3.
This is to determine the degree of

In this example, surfaces 6a and 6b are formed in the axial direction on a part of the outer circumferential surface of the swing center shaft 6, as shown in the fourth figure.
It is possible to come into contact with the leaf spring 9.

This is intended to facilitate the stabilization of the leaf spring at the position where it contacts this surface, thereby producing a click effect, but is not necessarily required.

Because of this configuration, when assembling, first insert the leaf spring 9 into the swinging center part 8 through the opening 8a, and then insert the swinging center part into the mounting part 7 of the rear frame 3 and the left side plate 7a in FIG. If the central shaft 6 is inserted into the opening 8a through the hole in the side plate 7a, and the swinging center part 8 is gradually brought into close contact with the mounting part 7,
The central shaft 6 passes through the other opening 8b and the other side 7b, and is fixed in contact with the protrusion 14.

After this, the rear frame 3 may be fixed to the front frame 2.

Turn the screws 11a and 11b to attach the leaf spring 9 to the bent part 1.
It is pressed against the central shaft 6 via 0a and 10b.

If the screw is tightened strongly, a large slip torque will be obtained between the shaft 6 and the leaf spring 9, and if the screw is loosened, the slip torque will be reduced.

To stand the watch 1 vertically, the stand 5 is swung in the direction of the arrow 15 as shown in the first figure, and when the stand 5' is placed in a horizontal position as shown by the chain line, the watch stands vertically.

In order to stand the watch at a desired tilt angle, it is sufficient to stop the swinging of the stand 5 in the direction of arrow 15 at the desired position.

For large rotational moment at this time, screw 11
A, 11 and b should be screwed in firmly and adjusted to a large slip torque.

Further, if the surface 6b is formed on the shaft 6 in accordance with the most frequently occurring angle of inclination, for example, 45 degrees, the leaf spring 9 will come into contact with the surface 6b at this angle of inclination, so that a click action can be achieved.

When storing the stand 5, it may be placed in the position shown by the solid line in FIG.

At this time, if the leaf spring 9 is brought into contact with the surface 6a of the central shaft 9, a click action will be applied to the position when the stand is stored.

The slip torque can be adjusted at any time after the stand is assembled.

As described above, according to the present invention, a long leaf spring is placed in opposition to the central axis of the swing, and the pressing force of the leaf spring against the shaft can be adjusted, so that it can be used as the tilt angle of a table clock increases. It can sufficiently withstand the rotational moment that increases due to movement, and can always hold a table clock or the like at any angle with stable force.

Since the pressing force of the leaf spring can be adjusted from the outside, it can be arbitrarily and easily adjusted when it is desired to increase the spring force during use.

If a click surface is provided on the shaft, it can be clicked at frequently used angles of inclination, and more stable holding can be achieved.
