Description

[Detailed Description of the Invention] The present invention relates to a stand 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 angle of inclination is determined by tightening or fixing with screws and nuts.

However, with such a configuration, as the angle of inclination from the vertical plane increases, the center of gravity of the table clock becomes further away from the center of rotation, resulting in a larger rotational moment, and beyond a certain angle, the tilted position cannot be maintained and becomes unstable. It became.

Furthermore, if it were to be supported even at a large angle of inclination, a correspondingly stronger support mechanism would have to be used, which would make the device bulky.

This invention eliminates the above-mentioned drawbacks. By providing multiple protrusions on both sides of the frame of a watch, etc., and holding these with the legs of the stand, the watch etc. can be tilted stably at any angle. It provides a stand that allows you to

Embodiments of the present invention will be described below based on the drawings.

In Figures 1 to 4, both sides 2 of a frame 1 of a watch, etc.
, 2, a plurality of protrusions 3, 3a, 3b, . . . are disposed oppositely and project outward.

These protrusions engage with retaining parts provided on the legs 6 of the stand, which will be described later, to hold a clock or the like, and are provided at positions corresponding to the respective inclination angles.

The stand 4 has a substantially U-shape formed by the legs 6 and the connecting portion 6a, and is configured to substantially surround the rear of the frame 1.

The legs 6, 6 are rotatably supported by pins 5 at opposing positions on the lower ends of both side surfaces of the frame.

A long retaining portion 7 is provided on the inner surface of the leg portion 6, that is, on the surface in contact with both side surfaces 2 of the frame body, and below this retaining portion, projections 3.3a, 3b, 3C... . . . is provided with a notch 8 into which it can fit.

With the above configuration, when setting the front face 9 of a clock etc. in a position where it is easy to see, by placing the stand 4 horizontally and tilting the table clock etc. to the desired angle, the front face 9 of the clock etc. When the protrusion 3 is at the 3' position, the retaining part 7 of the stand
, the inclined surface angle θ of the table clock etc. is reliably held at this position.

If you want to increase the angle of inclination further, by pressing down on a table clock, etc., either the frame 1 or the stand legs 6, or both, will bend due to the protrusions 3, causing the protrusions 3 to bend.
passes over the retaining part 7, enters the notch part 8, and enters the next protrusion 3.
a comes into contact with the retaining portion 7 at position 3a', and the inclination angle is maintained at this position.

As the usage conditions change in this manner, the protrusions 3 to 3C sequentially abut on the retaining portions with the pin 5 as the center of rotation, thereby maintaining their respective inclination angles.

When storing a table clock or the like, the stand 4 is tightly fitted into the rear part of the frame 1 (as shown by chain lines in FIG. 1).

At this time, all of the protrusions 3' to 3C' are in the notch 8.

Note that the configuration of the protrusions 3 to 3C is not limited to the upper side, and their spacing, number, etc. may be set as appropriate.

Each protrusion is provided with a recess 2a on both sides 2 of the frame body for housing the spring, as shown in FIG.
0 may be housed and the ball 11 may be inserted.

In this case, when the ball 11, which is a protrusion, rides over the engaging portion 7, the ball retreats into the recess 2a due to the compression of the spring 10, so that the inclination angle can be changed smoothly.

Note that in this case, the cutout portion 8 is not necessary.

Furthermore, even in the examples shown in Figures 1 to 5, if the elasticity of the legs or the frame is appropriately set, even without the notch 8, the frictional force between the inner surface of the legs and the protrusions, and the frictional force between the protrusions and the The holding force with the joining portion works synergistically to ensure sufficient holding even at large inclination angles.

According to the example shown in FIGS. 7-8, the protrusions 13, 13a,
13b and 13C are formed so that the diameters of the protrusions gradually increase upward.

In this case, the protrusions 13, 13a, 13b...
Since the holding force between the and the engaging part 7 also increases sequentially, it acts to cancel out the rotational moment that increases as the inclination angle of the table clock, etc. increases, so that the table clock, etc. is stably held with a constant force.

As described above, according to the present invention, the inclination angle of the table clock etc. is maintained by the engagement between the protrusion provided on the frame of the table clock etc. and the retaining part of the stand. Compared to a device that maintains the inclination angle at the center of rotation with the Can hold table clocks etc. with force and at any angle.

Further, since no holding force is applied to the center of rotation, there is no need to provide a holding mechanism in this part, and it is only necessary to be able to rotate freely, resulting in a simple configuration.

In addition, when changing the tilt angle, the table clock or the like can be simply pressed downward by hand, making it easy to operate when in use.

Furthermore, if the diameter of the protrusion on the frame is changed, the holding force increases in proportion to the rotational moment that increases as the inclination angle deepens, so it is possible to always hold a table clock etc. with a stable and constant force. can.
