DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fall prevention device for a legged device for preventing a fall due to vibration caused by an earthquake.

[0002]

2. Description of the Related Art Heretofore, among various devices, there is a legged device provided with legs at four positions in front, rear, left and right. A leg-mounted device has a smaller installation width than a device without a leg to be directly installed, and has a surface with a low center of gravity due to the legs, and lacks stability. Means of fixing and supporting directly on the installation surface using a mold is adopted.

[0003]

In order to prevent the equipment with legs from tipping over, it is necessary to make mounting holes on the equipment side and on the installation surface side, respectively, since an L-shaped fitting is used, and the installation work is troublesome. In addition, when the position is changed after the installation is completed, the mounting hole must be processed again, which is troublesome and time-consuming, and the installation cannot be easily changed.

Accordingly, the present invention focuses on the space formed on the bottom surface of the device main body by the height of the legs of the device with legs,
An object of the present invention is to provide a fall prevention device for a legged device that can reliably and firmly prevent a fall without processing a mounting hole or the like.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, there is provided an upper base member having an adhesive mat mounted on an upper surface thereof and having a rotation restricting portion;
A lower-side base member having a rotation-restricting portion opposed to the upper-side base member and constantly in contact with the rotation-restricting portion so as to be vertically movable, and an adhesive mat attached to a lower surface; And an adjustment support mechanism for bringing the adhesive mat of the lower base member into contact with the installation surface.

[0006] Thus, after the fall prevention device is placed and set in the space formed at the bottom of the legged device near the four legs, the adhesive mat of the upper base member is attached to the device body by the adjustment support mechanism. The installation is quickly completed by bringing the bottom surface of the base member and the adhesive mat of the lower side base member into contact with the installation surface, respectively.

Therefore, it is not necessary to machine the mounting hole, and the position can be easily changed after the mounting is completed.

On the other hand, the adhesive mats of the upper side base member and the lower side base member ensure a supporting state in which the adhesive mats are securely brought into close contact with the bottom surface and the installation surface of the device main body, respectively. However, we were able to confirm the prevention of falling by eliminating the positional shift of the equipment.

According to the second aspect of the present invention, the upper base member and the lower base member are formed in a plate shape, whereby the size from the lower base member to the upper base member is small and thin. If the space at the bottom of the device main body is large, it can be used even in a small space.
