Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device for a resin molded product, and more particularly to a mounting device for mounting a resin-molded glow socket body to a lighting fixture body directly or via a metal fitting.

Conventional glow socket bodies have generally been attached directly to the lighting fixture body, or by attaching metal fittings to the lighting fixture body and attaching them to the fittings with screws, screws, etc., respectively.

However, this installation method using screws or screws, etc.
Tightening not only makes the work troublesome, but also requires parts such as screws or screws, which causes high costs.

The present invention aims to improve and eliminate the above-mentioned conventional problems and provide a one-touch fitting device for attaching resin molded products.

The configuration of the present invention will be explained below according to the embodiments shown in the drawings.

1 to 3 show a glow socket body (hereinafter referred to as socket body) 1 which is a resin molded product.

In the figure, 2 and 3 are protrusions provided on the left and right sides of the mounting surface 4 of the socket body 1.

The projections 2 and 3 include a small diameter portion a having a thickness corresponding to the thickness of a mating member 5, which will be described later, and a large diameter portion continuous to the small diameter portion a.

Reference numeral 6 denotes a small protrusion provided approximately at the center of the mounting surface 4.

At the bottom of the socket body 1 located above the small protrusion 6, for example, a rectangular through hole 7 and a slit 8 in the horizontal direction along the mounting surface 4 are provided on the front side and the back side of the socket body 1, respectively. The through hole 7 and the slit 8 communicate with each other inside the socket body 1.

In particular, the slit 8 is chamfered so that it becomes narrower from the back side toward the back wall.

On the other hand, as shown in FIG. 4, the mating member 5 has fitting holes 10, 11, and 12 on its mounting surface 9, which correspond to the projections 2.3 and small projections 6 provided on the mounting surface 4 of the socket body 1. ing.

The fitting holes 10 and 11 have large diameter portions 10a and ila through which the large diameter portion a of the protrusion 2. The elongated hole 10b has a width approximately equal to the diameter of the small diameter portion of No. 3, 1
It has 0b.

By the way, the counterpart member 5 having such a configuration may be a lighting fixture main body, or may be a metal fitting attached to this lighting fixture main body.

Next, the case where the socket main body 1 is attached to the mating member 5 will be explained.

First, position the back side C of the socket body 1 on the end face opening side of the mating member 5, and fit the protrusions 2 and 3 of the socket body 1 into the large diameter holes 10a and 11a of the mating holes io and iv of the mating member 5. let

Then, the socket main body 1 is slid from the end surface A side of the mating member 5 toward the mouth side.

The socket body 1 is guided by the small diameter portions a of the protrusions 2 and 3 and the fitting gaps of the long holes 10b and llb of the fitting hole 10°11,
Eventually, one end surface of the small protrusion 6 comes into contact with the end surface A of the counterpart member 5, and the sliding is temporarily stopped.

When a further force is applied in the sliding direction to the socket main body 1 from this state, the bottom surface of the thin socket main body 1 on the small protrusion 6 side moves to the through hole 7 and slit 8 side, as shown in FIG. The small protrusion 6 is bent and rides on the mounting surface 9 of the counterpart member 5.

Subsequently, when further force is applied in the sliding direction to the socket body 1, the small protrusion 6 fits into the fitting hole 12 of the mating member 5, and at the same time, the small diameter portions a of the protrusions 2 and 3 fit into the end faces of the long holes 10b and 11b. They come into contact with each other, and the socket main body 1 is fixed to the mating member 5.

That is, the attachment of the socket body 1 to the mating member 5 is completed.

In this state, the socket body 1 is firmly fixed to the mating member 5 by the fitting relationship between the small protrusion 6 and the fitting hole 12 of the mating member 5, preventing the socket body 1 from being pulled out and shaking.

By the way, in the present invention, by providing the through hole 7 and the slit 8, it is possible to smoothly fit the small protrusion 6 into the fitting hole 12 when attaching the socket body 1 to the mating member 5. In addition, the following installations are possible using these.

That is, as shown in FIG. 6, the mating member 13 has a width that fits in the slit 8 of the socket body 1, and a tongue piece 14 with a width that fits in the through hole 7 is provided at the center of the tip end thereof. As shown in FIG. 7, a hemispherical cut-out piece 15 is provided protrudingly.

Note that the thickness of the counterpart member 13 corresponds to the thickness of the slit 8 and the through hole 7.

The slit 8 of the socket body 1 is inserted into the counterpart member 13 having such a configuration from the tongue piece 14 side.

The bottom surface portions of the slit 8 and the through hole 7 are bent downward and expanded by the length of the cut and raised piece 15, and as soon as the cut and raised piece 15 passes through the through hole 7, it returns with the restoring elasticity peculiar to the resin.

Therefore, the raised piece 15 hooks and locks onto the back surface of the socket body 1, and clamps the rear wall of the socket body 1 between it and the shoulder portions 16 and 17 of the distal end surface of the mating member 13.

In other words, the socket body 1 is firmly fixed. Therefore, by setting the thickness of the slit 8 and the through hole 7 to a thickness other than the small diameter portion, the present invention can be attached to two types of mating members.

As explained above, according to the present invention, a resin molded product can be attached to a mating member in a one-touch manner by simply pushing it in, without using screws or screws, and the attachment operation is extremely simple.

Further, since screws, screws, etc. are not required, the number of parts is small and the product can be provided at low cost.

Furthermore, it is convenient because it can be attached to two types of mating members.

Particularly, when the protrusion is attached to the fitting hole of the mating member, the mounting surface is deformed so as to be inserted into the through hole or slit by the contact of the small protrusion with the mating member, so that the ease of attachment can be significantly improved.
