Description

[Detailed Description of the Invention] The present invention relates to a device for fixing a frame member of a side cover of an electrical device, etc., which is relatively light and does not vibrate.

In a conventional device of this type, for example, a device for fixing frames 1 and 2 to which a cover B of a lighting fixture A is attached as shown in FIG.
As shown in Fig. 2, an L-shaped stopper 3 was passed between a pair of frame members 1 and 2, and the stopper 3 and frame members 1 and 2 were fixed with screws 4, etc. If not tightened, both frame members 1
, 2 may rattle and the stopper 3 may come off. Also, since the stopper 3, which is a separate part, is attached to the frame members 1 and 2, the frame members 1,
It took a long time to assemble the second item.

In view of the above-mentioned points, the present invention aims to provide a fixing device that can easily assemble and fix frame members, and can also firmly fix the frame members by simply tightening them slightly with screws.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 5. In the figures, 1 and 2 are frame members for attaching the cover B of the lighting fixture A, and the fixing device according to the present invention is as follows: A cantilevered elastic piece 5a is integrally formed of synthetic resin on the inner surface of the end of one frame material 1 and protrudes horizontally at right angles to the side surface of the frame material 1. The elastic piece 5 is attached to the inner surface of the end of the
A receiving piece 6a for fitting into the receiving piece 6a is integrally protruded from synthetic resin, and has a tapered shape for press-fixing the elastic piece 5a fitted to the receiving piece 6a to the receiving piece 6a in an elastically deformed state. A tapered screw 7 is fitted into the elastic piece 5a and the receiving piece 6a so as to bite into the elastic piece 5a and the receiving piece 6a.

Further, the elastic piece 5a is disposed on the upper part of the inner surface of the end of the one frame member 1, and the receiving piece 6b is disposed on the lower part, and the other frame member 2
The receiving piece 6a is on the upper part of the inner surface of the end, and the elastic piece 5 is on the lower part.
b is arranged.

Each of the elastic pieces 5 a and 5 b has a minute gap d
A pair of elastic elements 5C, 5d formed horizontally with
It is composed of

On the other hand, each of the receiving pieces 6a, 6b is connected to the elastic piece 5a, 5b.
A pair of receiving portions 6C and 6d are arranged in the vertical direction with a gap in which the elastic holes 5C and 6d can be fitted, and a pair of receiving portions 6C and 6d are disposed in the center between the receiving portions and fit into the gap d between the elastic holes 5C and 5d. elastic piece guide part 6
It is composed of e.

A tapered notch 8 into which the wooden screw 7 is fitted is formed in the guide portion 6e.

Next, to explain the operation, in order to fix the pair of frame members 1 and 2, first move the frame members 1 and 2 closer together as shown by the arrows in FIG. , 6b, respectively, and the backs of the elastic pieces 5a, 5b are brought into contact with the inner surfaces of the frame members 1, 2.

In this case, since the elastic pieces 5a and 5b protrude from the frame members 1 and 2 at right angles, both frame members 1 and 2 intersect at right angles.

Then, the screws 7 are fitted into the notches 8 of the guide portions 6e of the receiving pieces 6a, 6b, and the elastic pieces 5a, 5b and the guide portions 6
If the tapered screws 7 are fitted into the holes 6c and 5d, the tip ends of the pair of elastic elements 5C and 5d will be separated from each other, forming the pair of receiving portions 6C96d of the receiving pieces 6a and 6b.
press against.

Therefore, the elastic piece 5a of one frame member 1 can be prevented from sliding in the upward direction along the inner surface of the other frame member 2, and the screw 7 can be prevented from biting into the guide portion 6e and the elastic piece 5a. Since the elastic piece 5a is fitted, it is possible to prevent the elastic piece 5a from coming out from the receiving piece 6a toward the head side of the screw 7, that is, in the upward direction. Since the elastic piece 5a is interposed in the receiving piece 6a, it is possible to prevent the elastic piece 5a from being pulled out in the upward and downward direction, and as a result, the elastic piece 5a cannot be pulled out from the receiving piece 6a in three directions.

Furthermore, in this example, each of the frame members 1 and 2 is provided with an elastic piece 5a,
5b and receiving pieces 6a, 6b, the frame members 1, 2
is more firmly fixed.

In addition, in the present invention, the elastic pieces 5a, 5b and the receiving piece 6a
, 6b are made of metal or synthetic resin, but if they are made of synthetic resin, screws 7 are provided in order to bite into the elastic pieces 5a, 5b and the receiving pieces 6a, 6b. Requires threaded groove.

It is preferable to use sharp pitched wood screws instead of smooth pitched screws.

As is clear from the above description, the present invention is a fixing device for fixing a pair of frame members such as electrical equipment, in which a pair of frame members is arranged in parallel with each other at the end of one frame member with a small gap d. Cantilevered elastic pieces 5a, 5 consisting of a pair of elastic elements 5C, 5d
A pair of receiving portions 6C and 6d are provided integrally and projectingly, and are arranged in parallel at the end of the other frame member with a gap that allows the elastic piece to fit externally. The elastic element 5C arranged in the center
, 5d, an elastic piece guide portion 6e with a notch that can fit into the gap d between
Receiving pieces 6a and 6b are provided, and the elastic element fitted between the receiving part and the elastic piece guide part is elastically deformed toward the receiving part, and the elastic element is elastically deformed to the inner surface of the receiving part. A screw 7 for press-fitting and fixing is fitted into the notch 8 of the elastic element, the receiving piece part and the elastic piece guide part.

Therefore, according to the present invention, instead of screwing the screw all the way to its head, the screw is only slightly bitten into the elastic piece and the receiving piece, and the pair of elastic elements of the elastic piece are inserted into the receiving piece. The frame material can be firmly fixed by being press-fitted to the inner surface of the receiving part, and even if the gap between the receiving part and the elastic piece guide is set to be slightly larger than the thickness of the elastic piece, the elastic piece will not be deformed by the screw. So,
The elastic element can be fixed extremely firmly to the receiving part, making it easy to fit the elastic element. Furthermore, since the elastic piece and the receiving piece are integrated with the frame material, assembly and fixing of the frame material is easy. It has excellent effects and can be done quickly.
