JPS584302Y2 - Television receiver plaque mounting device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plaque mounting device for a television receiver.

Doors used in television receivers are often molded from synthetic resin and have an aluminum plaque glued to the surface.

Since the coefficient of thermal expansion of the door and the aluminum plate is different, there will be a difference in the mutual expansion and contraction.

At this point, warping will occur if the rigidity of the adhesive between the door and the aluminum plate is weaker than the mutual expansion and contraction force.

To increase the rigidity of a door and an aluminum veneer glued together,
It is necessary to increase the inner thickness of each other, add ribs, and add aluminum, which increases costs.

Furthermore, if the mutual rigidity is made sufficiently strong, if the adhesive strength between the aluminum pelmet and the door is weaker than the mutual expansion and contraction force, the mutual adhesive will peel off and the adhesive strength must be increased, again causing an increase in costs. becomes.

The unique feature of this invention is that it eliminates the above-mentioned conventional drawbacks and is a mounting device that prevents warping that occurs due to the difference in thermal expansion when attaching an aluminum plate to an adherend such as the door of a television receiver made of synthetic resin. is to provide.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, an aluminum decorative plate 1 has a protrusion 3, and a door 4 has a hole 5 into which the protrusion 3 is inserted.

A cushioning material 2 is inserted between the aluminum decorative plate 1 and the door 4, and after inserting the protrusion 3 into the hole 5, the aluminum decorative plate 1 is attached to the door 4 by bending the protrusion and the protrusion 3 as shown in FIG.

At this time, since the cushioning material 2 is placed between the aluminum decorative plate 1 and the door 4, an appropriate pressing force is constantly applied between the bent portion of the protrusion 3 and the door 4 due to the elasticity of the cushioning material 2, thereby preventing backlash. Aluminum decorative plate 1, cushion material 2, and door 4 are mutually displaced due to differences in thermal expansion due to temperature differences.
By mutually shifting, it is possible to prevent warpage from occurring.

In this way, the hole 5 of the door 4 according to the present invention is formed by the aluminum decorative plate 1.
It has a sufficient size so that the end faces of the aluminum decorative plate protrusion 3 and the hole 5 will not come into contact and restrict their movement even if there is mutual displacement caused by the difference in the coefficient of thermal expansion between the aluminum decorative plate protrusion 3 and the door 4. Insert the cushioning material 2 between the board 1 and the door 4, insert the aluminum decorative plate protrusion 3 into the hole 5 of the door 4, and then bend the door 4 so as to insert it and attach the decorative plate 1 to the door 4. For example, the aluminum decorative plate is held not only by the plastic deformation of the protrusions 3, but also by the elasticity of the cushioning material 2, a moderate pressing force is applied between the decorative plate 1 and the door 4, eliminating play. When the displacement force due to thermal expansion of the aluminum decorative plate 1 and the door 4 becomes stronger than the pressing force, misalignment occurs between the decorative plate 1 and the cushion material 2, and between the cushion material 2 and the door 4, and warping can be prevented. .

As described above, according to the present invention, when attaching an adherend such as a television receiver door made of synthetic resin to an aluminum plaque, it is possible to eliminate the difference in thermal expansion between the two, which was a problem with conventional methods. This has the effect of completely preventing the occurrence of warping and making it possible to have an inexpensive structure.
