Abstract

PURPOSE:To make it possible to process static electricity securely in a simple structure by providing a conductive brush at one of a supporting body of a sliding body and the sliding body, and guide rails where the conductive brush contacts at the other. CONSTITUTION:Guide rails 3, 4 consisting of stainless plates are provided facing each other on both inner sides of a supporting body 1 and both outer sides of a drawer 2, and a conductive brush 8 is provided horizontally by means of a screw 7 at an angle 6 fixed at one inner side of the supporting body 1. The conductive brush 8 protrudes through a slit 31 provided along the length of the center part of the guide rail 3 to the side of the guide rail 4 on the side of the drawer 2 to contact the protruding side of the guide rail 4. If static electricity is produced by friction between the guide rails 3, 4 when the drawer 2 is used, the static electricity is let to escape through the angle 6 with the supporting body 1 acting for earth because the conductive brush 8 contacts the guide rail 4 constantly.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for treating static electricity generated in sliding parts such as metal desks and cabinet drawers.

(Prior Art) In recent years, computers have become more sophisticated and smaller, and desks and cabinets incorporating computer bodies and terminals have come into widespread use.

As computers become more sophisticated, the elements built into them have become more sensitive to the environment, and in particular malfunctions due to static electricity have become a major problem, and various countermeasures have been taken. One countermeasure is to connect each part with a ground wire or apply masking paint to the parts where they are connected to ensure continuity, and to release the static electricity to other parts. However, it was not sufficient as a countermeasure against static electricity in sliding parts such as drawers.

Therefore, as a countermeasure against static electricity in sliding parts such as drawers, methods such as connecting the drawer and the main body with a ground wire, and the so-called pantograph method in which a springy metal piece is slid on a conductive metal rail have been used. Proposed.

(Problems to be Solved by the Invention) According to the former method of using a ground wire, the ground wire may get caught or become tangled with the constituent members of the drawer when the drawer is taken out or put in, and when the drawer is pulled out, There was the trouble of having to remove the ground wire. In addition, the latter pantograph method has the disadvantage that metals come into contact with each other, which causes wear and generates a harsh frictional noise when sliding.

SUMMARY OF THE INVENTION An object of the present invention is to provide a static electricity treatment device for sliding bodies such as drawers that does not require troublesome handling and does not generate unpleasant frictional noises when sliding.

(Means for solving the problems) The present invention provides a conductive brush 8. The other side is provided with guide rails 3°4.3a and 4a with which the conductive brush contacts.

(Function) During use, static electricity generated as the sliding bodies 2, 2a slide is removed through the conductive brushes 8, 8a, and the supporting bodies 1, 1a or the sliding body 2.2a to which they are attached act as a ground. miss

(Example) An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

A drawer 2, which is a sliding body, is provided in a supporting body 1 of a drawer made of metal so that it can be taken in and out.

Guide rails 3 and 4 made of stainless steel plates are provided on both inner sides of the support body 1 and on both outer sides of the drawer 2 in opposing positions.
This is provided. The guide rail 3 on the side of the support body 1 is formed in a channel shape, and is fixed to the inner surface of the support body 1 with a mounting bracket 5.

The guide rail 4 on the side of the drawer 2 is formed into a bridge shape in cross section, and its protrusion is slidable within the guide rail 3 on the side of the support body.

By the way, a conductive brush 8 is attached to an angle 6 fixed to the inner surface of one side (right side in FIG. 1) of the support body 1 with a screw 7.
It is installed horizontally. The conductive brush 8 protrudes toward the guide rail 4 on the drawer 2 side through a long hole 31 provided in the center of the guide rail 3 in the longitudinal direction, and is in contact with the side surface of the protrusion of the guide rail.

Therefore, when using the drawer 2, the guide rails 3 and 4
When static electricity is generated due to friction between the brushes, the conductive brush 8
Since it is in contact with the guide rail 4, the support body 1 becomes grounded through the angle 6, and static electricity can be dissipated.

In this example, the conductive brush 8 is directly attached to the support body 1, but instead of this, the upper horizontal portion 32 of the lower guide rail 3
(FIG. 1) and may be brought into contact with the guide rail 4.

Further, other examples are shown in FIGS. 4 and 5. In this example, a conductive brush 8a is attached to one side of the drawer 2a via an angle 6a. The tip of the conductive brush 8a is always in contact with the inner surface of the guide rail 3a on the support body 1a side through the long hole 41a of the guide rail 4a.

In this example, when static electricity is generated, the user becomes grounded through the drawer 2a.

The present invention can be used not only for desks but also for metal furniture such as cabinets.

(Effects of the Invention) According to the present invention, static electricity can be reliably disposed of with a simple configuration, and the conventional problems of entanglement of ground wires when handling moving objects such as drawers and generation of friction noise when sliding are avoided. Therefore, it can be easily applied without significantly changing the sliding mechanism of current desks, etc.
