Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a metal support used for attaching an automobile ceiling material to a vehicle body.

Various methods are used to attach automobile ceiling materials to the vehicle body, and one method, as shown in FIG. 1 and FIG. There is a method of driving the receiver into a predetermined position, inserting the insert 21A into the metal 21, and inserting the head 21'A of the insert 21A into the insertion hole 22B of the garnish 22A provided at the front of the ceiling panel 22.

Conventionally, this type of support has a metal base 11 and a leg force 12 extending vertically from the four corners of the lower surface of the base 11, as shown in FIG. When the ball is hit, the leg force 12 may bend inward or outward as shown in FIG. 4, and the angle of bending is not constant.

If there are such variations in the way the leg force 12 bends, the strength of the gold fixation of the receiver may vary, and the surface of the ceiling material 13 may bulge.

For example, if the angle of bending of the leg force 12 is small, the gold will easily come out of the receiver, and if the angle of bending of the leg force 12 is small, the gold will easily come off the receiver. If it is too small, the tip of the leg force will reach near the surface of the ceiling material 13 and press the vicinity of the surface of the ceiling material 13, resulting in the ceiling material 13
A bulge 13A is produced on the surface.

An object of the present invention is to improve the above-mentioned drawbacks, and when driving metal into a ceiling material, the receiver makes the bending direction and bending angle of the metal legs substantially constant, thereby improving the fixing force of the metal legs and eliminating variations. At the same time, the purpose is to prevent the surface of the ceiling material from blistering, and the main point is that the legs are opened outward at an angle of 10±2°.

The present invention will be described with reference to an embodiment shown in FIG. Served.

Leg strength 2 is opened outward at an angle of 10±2°.

The above receiver is attached to a predetermined location of a molded ceiling material 3 consisting of a laminate of a so-called resin board 3A in which gold A is bonded with fibers using a synthetic resin binder and a facing material 3B in which a polyvinyl chloride sheet is mounted on a urethane foam. To drive, as shown in Fig. 1, a recess 4A is provided on the upper surface of the receiver to which the metal A plywood part 1 is to fit, and a magnet 5 is attached to the center of the recess 4A. When the plywood part 1 made of gold A is fitted into the recess 4A of the fitting 4, the gold A plate is magnetically fixed by the magnet 5.

In this way, the receiver A is attached to the driving tool 4.

At this time, in order to make the angle of the leg force 2 of the metal A meaningful, the above-mentioned receiver should be placed in the recess 4A of the driving tool 4 as shown in FIG.
It is necessary to make the depth of the support approximately equal to the thickness of the base plate part 1 of gold A so that the recess 4A accommodates only the base plate part 1 and allows the leg 2 portion to come out from the recess 4A.

For example, if the leg force 2 portion is also accommodated in the recess 4A, the peripheral wall of the recess 4A will prevent the leg force 2 from opening outward when driving into the ceiling material.

In this way, the receiver presses the driving tool 4 with metal A attached to a predetermined location of the ceiling material 3 placed on the base 6.

At this time, if the recess 4A is not formed in the metal A attachment part of the receiver of the driving tool 4, the leg force 2 may not be driven into the ceiling material 3 due to the pressing resistance and may open.

The side wall of the recessed portion 4A is made of plywood portion 1 of gold A for the receiver in the case of - driving.
By fixing the periphery, the receiver prevents the gold A from shifting.

Thus, as shown in FIG. 8, the bracket A is driven into the ceiling material 3, and its leg force 2 uniformly opens outward at a substantially constant angle due to the internal resistance of the ceiling material 3.

Table 1 shows the relationship between the angle of the leg force of the uke hakin and the variation in the bending of the leg force when the uke hakin is driven.

Table 1 shows the results of a test conducted on 1000 gold supports by hammering them into ceiling materials.

One uke is about gold and there are four legs, so M240
It is 00.

Looking at Table 1, when θ=8°, the leg force always bends outward, and no blisters are observed on the surface of the interior material.

If θ exceeds 12°, the leg force will not be able to sink into the interior material and will open up on the surface layer.

For the main receiver A, insert the insertion fitting 4 into the lower part of the base part 1 of the receiver A as shown in FIG.

Thus, in Fig. 10, the book holder is the ceiling material 3 to which gold A is attached.
This ceiling material 3 is attached to an automobile ceiling panel in a manner similar to that shown in FIGS. 1 and 2.

In the receiver of the present invention, the legs 2 extended from the four corners of the lower surface of the plywood part 1 are opened outward at an angle of 10±2°, and in order to drive this, the receiver is attached to the upper surface. Plywood part 1 of A
Using a driving tool 4 provided with a recess 4A that fits properly and has a depth equal to the thickness of the plywood part, the recess 4A of the driving tool 4 is used.
By fitting the plywood part 1 of gold A into the receiver, the receiver becomes gold A.
Since it is attached to the driving tool, when it is driven into the ceiling material, the leg force 2 is smoothly embedded into the ceiling material, and the leg force 2 is attached to the driving tool recess 4A.
It always bends outward without being obstructed by the surrounding wall, and the angle of bending is also approximately constant.

Therefore, the adhesion force of the gold to the ceiling material is improved and remains approximately constant, and no bulges are corrected on the surface of the ceiling material.
