Description

[Detailed description of the invention] This invention relates to a handle attachment device used for radio receivers, tape recorders, and other equipment, which has a simple structure, can be easily and securely attached, and provides stable rotational frictional force. The object of the present invention is to provide an excellent handle attachment device that can be used.

Generally, when attaching a handle to a cabinet, the shaft of the handle is inserted into a hole formed in the cabinet, and a stopper is attached to the tip of the shaft inserted into the hole, so that the handle can be rotated freely. It is. However, in this case, in order to ensure sufficient rotational friction force of the handle, a considerably complicated structure is required, which is not very desirable.

The present invention eliminates the above-mentioned conventional drawbacks and provides an excellent handle attachment device that can secure sufficient rotational frictional force with a simple configuration.

Hereinafter, the handle attachment device of the present invention will be explained with reference to drawings of embodiments. In the figure, 1 is a cabinet, 2 is a through hole for a bearing formed in the side plate 1a of the cabinet 1, 3 is a pillow that is integrally formed on the inner surface of the cabinet 1 and has an arcuate bearing part 3a at the tip, and 4 is a A handle, 5 is a shaft attached to the end of the handle 4, 6 is a ring-shaped groove formed in the central outer circumference of the shaft 5, and 7 is fitted to the shaft 5 and is attached to the outer wall of the side plate 1a of the cabinet 1. and the handle 4, 8 is a boss formed at a position facing the concave groove 6 of the shaft 5 when the shaft 5 is inserted into the through hole 2, 9 is one end is a plate spring which is tightened and fixed to the boss 8 by a screw 10, and whose other end is pressed into a concave groove 6 of the shaft portion 5 of the handle 4 which is inserted into the through hole 2 and supported by the pillow 3; 11 is a cabinet; 1 side plate 1
This is a recessed notch that is formed on the outer wall of a and restricts the rotation angle of the handle 4 to a range from the first solid line to the dotted line.

In the above embodiment, when attaching the handle 4, first fit the washer 7 to the shaft 5, and then insert the shaft 5 into the through hole 2 in this state. The outer peripheral portion of the tip abuts against the arcuate bearing portion 3a of the pillow 3. Therefore, in this state, one end of the leaf spring 9 is brought into contact with the groove 6 of the shaft portion 5, and the other end is tightened and fixed to the boss 8 with the screw 10.

By doing so, a large pressing force from the leaf spring 9 acts on the groove 6 of the shaft portion 5, and a sufficient rotational friction force of the handle 4 is ensured. Since the leaf spring 9 is in contact with the groove 6 of the shaft portion 5, the shaft portion 5 will no longer come out, and the handle 4 will be firmly and stably attached.

As is clear from the above embodiment, in this invention, a ring-shaped groove is formed in the shaft of the handle, and a leaf spring is pressed against the groove to apply sufficient rotational friction force to the shaft. The handle is regulated to prevent it from slipping out, the overall structure is extremely simple, and sufficient rotational frictional force is obtained from the handle, which is extremely advantageous in practice. Moreover, the leaf spring that is pressed against the ring-shaped groove provided on the outer periphery of the shaft of the handle has a through hole and a pillow formed to support the handle so as to correspond to a line segment perpendicular to the shaft. Since the leaf spring is screwed onto a boss provided on the inner surface of the cabinet, it has the advantage of being easy to install.
