This article relates to a footrest device.

[Conventional technology]

Conventional footrest devices of this type are, for example,
As disclosed in Publication No. 7299, one side of two support rods is rotatably supported on both sides of the foot space of the desk, and a mounting plate is placed between the other ends relative to the support rod. A rotatably supported chair is provided, but when the foot is placed on the placement plate, the top surface of the foot is always in contact with the sole of the foot, and when the chair is pushed into the foot space, the Although moving the placing plate backwards was effective, it was extremely unstable during use and dangerous when rising suddenly. Further, as disclosed in Japanese Utility Model Application Publication No. 59-29938, the mounting plate is pivoted to the side plates on both sides of the foot space of the desk using pins protruding from both sides of the rear end of the mounting plate. A foot rest device is provided in which the above-mentioned placing plate is supported substantially horizontally with support dowels protruding from the front of the side plate, but although it is stable during use, it is difficult to store the chair in the foot space. In this case, the mounting plate must be rotated rearward by hand or foot, which poses a problem in operability.

[The problem that the idea attempts to solve]

In view of the above-mentioned situation, the present invention aims to solve the problem by providing extremely stable operation when using the chair with the feet placed on the placing plate, and also ensuring that the placing plate does not move when the chair is pushed into the foot space of the desk. To provide a footrest device for a desk that automatically rotates rearward and allows a chair to be easily stored in a foot space.

[Means to solve the problem]

In order to solve the above-mentioned problem, this invention rotates the mounting plate on both side plates facing the foot space of the desk using a pivot attached to the lower end of the mounting bracket that protrudes downward from the rear of both sides. A support dowel is protrudingly provided at the side plate position forward and above the pivot point to support the mounting plate movably and to hold the mounting plate substantially horizontally in a freely rotating state, and furthermore, the mounting plate is held in a predetermined position. A footrest device for a desk is constructed by protruding from a proper position on the side plate a stopper that prevents the rearward rotation in a state in which the footrest is rotated angularly upward and rearward.

Further, the center of gravity of the mounting plate and the mounting bracket as a whole in a state where rearward rotation is prevented by the stopper is configured by protruding the stopper at a position forward of the pivot point.

Furthermore, a mounting bracket is provided in which one piece of the L-shaped metal fitting bent at a right angle is used as a mounting piece to the aforementioned mounting plate, the other piece is used as a hinge piece, and a pivot is provided on the side at the end of the hinge piece. It was constructed using

The mounting plate is configured by fixing a slider to the front end thereof, by forming a slope inclined downward and rearward, or by protruding a roller.

[Effect]

The desk footrest device of the present invention, which is constructed as described above, pivots the rear portions of both sides of the placement plate to the side plates on both sides of the foot space of the desk using mounting brackets, and makes the placement plate substantially horizontal. Since the mounting plate is supported by support dowels protruding from the side plate, the mounting plate does not move when the feet are placed on the mounting plate, and the lower ends of the mounting brackets protruding downward from the rear of both sides of the mounting plate. By pivoting on a pivot provided on the side of the section, and positioning the supporting dowel to protrude from the side plate forward and above the pivot point,
When the chair is pushed into the foot space, the mounting plate automatically rotates upward and backward until it is stopped by a stopper.

In addition, by setting the protruding position of the stopper so that the center of gravity of the mounting plate and the entire mounting bracket, which are prevented from rotating backwards by the stopper, is in front of the pivot point, the chair, etc. When the backward rotational force is released, the mounting plate automatically rotates forward and restores the state on which the feet can be placed.

Further, by providing a slider, an inclined surface, or a roller at the front end of the placing plate, the backward rotation of the placing plate when the chair is pushed is made smoother.
