Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a stand mechanism for installing small tabletop devices and instruments on a stand or the like with a fixed structure.

2. Description of the Related Art For data input in information processing systems, so-called cordless input devices are widely used in small machines and various terminals, which allow the direct input of a wide variety of items, a large number of items, or characters without using codes.

For example, if a keyboard is used in such a device, a CRT
A display device, FDP device, etc. consists of a keyboard section, a display tube section, an operation section, etc., and the display tube section, which has a display surface on which images such as characters and images are displayed, is placed on the desk of the installation stand, etc. is set up.

For example, as shown in FIG. 1, the display tube section of this display device is constructed such that the display tube section 1 is mounted on a rotary mechanism 3 provided on a base 2 that can freely rotate and swing, so that the angle of the display surface 4 can be changed. The base 2 can be placed on a desk 5 or the like for easy viewing.

By the way, recent office display devices, etc.
Depending on the operation or purpose, there is a demand for a tabletop type with a swinging structure, and a design that is similar to a stand and is small and smart.

However, with the current fixing method, the rotation mechanism 3 is able to swing and rotate as shown in Figure 1, but the structure of the display tube section 1 is fixed because it is fixedly installed on a desk 5 or the like to maintain stability. Therefore, the base 2 of the mounting base is also large and heavy, and furthermore, there is a disadvantage that it is difficult to move due to the weight.

Therefore, the purpose of the present invention is to eliminate the above-mentioned drawbacks, and is to provide a stand mechanism that has a fixed and movable structure that can withstand the weight of a display device, etc. on the upper part of the stand, by making the polished surface of the stand as small as possible. The purpose of this system is to provide a stand mechanism that comprises a suction fixing structure consisting of a presser plate linked to a lever and an elastic body on the bottom surface of the lower part of the stand for installing small tabletop devices and instruments, etc. on an installation stand. The suction and fixing mechanism includes a lever that swings around a rotational fulcrum fixed to the lower frame of the stand, and an elastic body whose disc-shaped lower surface is in close contact with the installation surface and which is connected to the lever at the center of the upper surface. and a holding plate having a retaining part facing one end of the lever and a pressing part that contacts the peripheral part of the elastic body, and the lever is swung about a rotational fulcrum in a direction to separate the elastic body from the installation surface. At times, one end of the lever engages with the holding part of the holding plate, and the pressing part presses the peripheral part of the elastic body, and the contact surface of the elastic body is deformed, creating a negative gap between the installation base and the elastic body. It is constructed by creating a pressure-tight space.

Below, one embodiment of the stand mechanism according to the present invention is shown in Fig. 2, a cross-sectional front view configuring its suction and fixing structure, Fig. 3 a, a perspective view of the main parts configuring it into a stand, and Fig. 3 b, a perspective view of the main part configuring it into a stand. This will be explained using a perspective view of the structure.

As shown in the figure, the stand mechanism of the present invention is used for small tabletop devices and utensils, etc. A suction fixing structure is provided on the bottom of the stand with a swinging structure, and it can be moved and fixed by operating the lever, providing stability against falling and movement. It is possible to increase the

The stand mechanism of the present invention is as shown in Figure 2.
A suction fixing mechanism 8 is provided on the lower bottom surface 7, and the suction fixing mechanism 8 rotatably supports the lever 10 at a fixed fulcrum 9 of a shaft fixed to the frame of the stand bottom surface 7. 1 faces the engaging portion 15-1 of the presser plate 15.

On the other hand, the lever 10 is rotatably connected to a connecting plate 12 by a rotating shaft 11, and the upper part 13 is rotatably connected to a fulcrum at the lower end of the connecting plate 12. A body 14 is formed.

The disc-shaped lower surface of the elastic body 14 is in close contact with the surface of the installation base, and the lower part of the presser plate 15 is in contact with the periphery of the upper surface.

Further, the holding plate 15 is connected to a stand bottom plate 16 to hold the stand 6 as shown in FIG.

In the stand mechanism constructed in this manner, as shown in FIG. At the center, the tip 10-1 of the lever 10 presses the engaging portion 15-1 of the presser plate 15, and the pressing portion 15-2 presses the disk-shaped periphery of the elastic body 14.

At the same time, the rotating shaft 11 moves upward, and the upper part 13 of the elastic body 14 swings upward via the connecting plate 12.

Then, due to the elasticity of the elastic body 14, a negative pressure is generated in the internal air on the surface that is in close contact with the installation table, and the suction force of the elasticity causes the elastic body 14 to
3, the stand 6 on which the device is mounted is fixedly installed on the desk top 5 or the like of the installation stand, as shown in FIG.

Next, when moving the device, move the lever 6 in the direction of the right arrow a.
If it swings as shown in Figure 2, the lever tip 10-1
is rotated at the rotation fulcrum 9 to release the pressure on the presser plate 15, and the upper part 13 presses the elastic body 14 downward due to the swinging of the connecting plate 12 interlocked with the lever 10, and the negative pressure of the internal air is released. The suction fixing mechanism 8 is released, and the third
As shown in the figure, it can be moved by a swingable stand 6 connected to the display tube section 1 having a display surface 4.

Therefore, with such a stand mechanism, the display tube 1 etc. of the display device can be easily and stably fixed on the desk 5 etc. by the elasticity of the elastic body 14 and the pressure of the presser plate 15 by operating the lever 10 of the suction fixing mechanism 8. If the lever 10 is released, the device can be easily moved from the desk 5 or the like.

In addition, as another embodiment, the embodiment of the stand mechanism of the present invention has been explained using a display device, but as an application of this, for example, the suction fixing mechanism 8 may be provided on a stand for a tabletop fluorescent light of an electric appliance. Accordingly, the aforementioned lever 1
It can be easily fixed to a desk 5 etc. with 0 operations, or moved by releasing it.

As explained in the embodiments above, according to the stand mechanism of the present invention, the suction and fixation mechanism allows the elastic body to be sucked and released by operating the lever of the structure, thereby easily fixing the device or the like on a desk or the like. Since it can be moved again,
The stand is small and lightweight, making it easy to move, and has the advantages of increased stability because it is fixed by the negative pressure of the elastic body using the holding plate.
