JPS599390B2 - How to install a receiver on an automobile molded ceiling - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION One method for attaching a molded ceiling to an automobile body is to drive the receivers 7 into predetermined positions on both edges of the ceiling material 8, insert the metal fittings 7A into the receivers 7, There is a method of inserting the head 7'A of the insert 7A into the insertion hole 10B of the garnish IOA provided at the front and rear of the ceiling panel 10.

FIG. 3 shows a conventional method of driving a receiver into a ceiling material that is attached to a vehicle body using this type of method.

That is, the receiving metal 13 is held with the leg blade 13A facing downward on a driving tool having a magnet 12 attached to the center of the lower surface of the base 11, and the interior material 14 placed on the support base 15 is placed underneath.
1 by pressing the driving tool downward.
3 was being driven into the interior material 14.

At this time, since the retainer 13 is held on the lower surface of the holder by the magnetic adsorption of the magnet 12, there is a high risk that the position and orientation of the retainer 13 may shift when driving the retainer 13 into the interior material 14. .

Furthermore, the mounting of the receiving metal 13 on the lower surface of the driving tool is done manually, and it is difficult to maintain a constant mounting position and direction, especially when a large number of receiving metal 13 are successively installed.

In addition, the length of the leg blade of the receiver 13 and the unevenness of the bevel, the interior material 1
4. Due to the presence of unevenness on the surface, etc., the receiving plate 13 is
It is almost impossible for all the leg blades to come into contact with the surface of the interior material 14 at the same time when driving, and therefore the position and direction of the receiver 13 almost always deviates during driving.

Therefore, in most cases in the conventional method, the positions of the receivers 13 driven into the interior material 14 are slightly shifted from each other, or the orientations of the receivers 13 are not constant.

The present invention improves the above-mentioned drawbacks of the prior art, makes it easy to install the driving tool in a fixed position and orientation, and prevents the position and orientation from shifting when driving into interior materials. The purpose of this tool is to accurately drive the receiver into a predetermined position, and it uses a driving tool with a magnet installed in the center of the upper surface of the base and support frames attached to both edges so that they can move in and out. The main points are as follows.

The present invention will be described with reference to an embodiment shown in FIG. is provided, the fitting groove 2 communicates with the outside through the outer structure 2A, and a stepped portion 2B is provided below the fitting groove 2. Further, a support frame 3 is slidably fitted into the support frame 3. has spring grooves 3A near both ends,
A spring 4 is inserted into the spring groove 3A from the base of the fitting groove 2, and a stepped portion 3B that engages with the stepped portion 2B of the fitting groove 2 is provided on the inner surface of the support frame 3.

Four parts 5 are provided on the upper surface of the base part 1 in accordance with the shape of the base part of the receiver 7 to be held, and a magnet 6 is embedded in the center part of the four parts 5.

The upper surface of the base part 1 of the main driving tool having the above-mentioned structure is used as a holding part, on which the receiver 7 is placed, and the receiver 7 is held by being magnetically attracted by the magnet 6.

At this time, the support frame 3 supports the receiver 1 from both sides of the receiver 7 via the leg blades 7B of the receiver 7, so when the receiver 7 is manually placed on the holder, the support frame 3 supports the receiver 1. 7 to a predetermined position and orientation.

After holding the receiver 7, the support rod 3 comes into contact with the leg blade γB of the receiver 3 to prevent the receiver 7 from shifting in position and direction.

Once the receiver 7 is placed on the driving tool, an interior material such as a ceiling material 8 is placed thereon.

Furthermore, the receiving metal 7 is driven into the ceiling material 8 by pressing it in the direction of the arrow in FIG. 7 using the pressing tool 9 from above.

At this time, as described above, the leg blade 7B of the receiver 7 is attached to the support frame 3.
Since the receiving plate 7 is in contact with the supporting plate 7, the position and direction of the receiving plate 7 are fixed by the support frame 3, and the supporting frame 3 lowers against the spring force while fixing the receiving plate 7 in this way.

As shown in FIG. 7, at the same time as the leg blade 7B of the receiver 7 is driven into the ceiling material 8, the support frame 3 is pushed by the surface of the ceiling material 8 and separates from the leg blade 7B, but at this time the leg blade 7B has already been Since the bracket 7 is slightly driven into the ceiling material 8 at a predetermined position and orientation, the receiver 7 is driven deeper while its position and orientation are fixed.

In addition, since the leg blades 7B of the receiver 7 are provided with a slight outward opening, the resistance of the ceiling material 8 during driving opens them further outward as shown in FIG. 8, thereby increasing the pull-out strength of the receiver 1. becomes a dog.

After driving the receiving metal 7, if the pressing tool 9 and the ceiling material 8 are removed from the driving tool, the support frame 3 will rise again by the spring force.

Thus, as shown in FIG.
is fixed.

The ceiling material 8 to which the support plate 7 is fixed in this way is shown in Fig. 1.
Attach to the vehicle body in the same manner as shown in Figure 2.

In this embodiment, the receiver is driven into the interior material by lowering the pressing tool with the driving tool facing upward, but it is also driven into the interior material by lowering the driving tool itself with the driving tool facing downward. You can put money into it.

As described above, the present invention fixes the mounting position and orientation by magnetically attracting the receiver with the magnet attached to the center of the upper surface of the base, and supporting the receiver from both sides of the receiver with the support frame. Therefore, when attaching the receiver to the deep holder, the receiver is guided by the support frame so that it is placed on the driving tool in a predetermined position and orientation. The mounting position and orientation of the receiver are fixed even when the receiver is driven into the ceiling material, so the receiver can be driven into the interior material at a predetermined position and in a predetermined direction accurately. becomes possible.

Furthermore, since the support frame is retractable, it does not become an obstacle when inserting the receiver.
