Description

[Detailed description of the invention] This invention relates to a clip for removably fixing a C-shaped cross-section member on a metal plate, particularly a clip suitable for fixing a molding to the body of an automobile. It is written as mall.

) and a mounting body that is attached to a hole in a metal plate. It was designed to be removably fixed on a metal plate.

The present invention will now be described with reference to the illustrated embodiments.

A indicates a molding, and B indicates a metal plate.

In this embodiment, the molding A has a metal channel material a as its core and a plastic material a′ on its outer surface using the insert molding method.
The metal plate B has a plurality of mounting holes dotted in rows along the mounting position of the molding.

1 is an insert made of plastic, which can be inserted from one end into the metal channel material a of the molding, or inserted into the channel material with the long side facing the longitudinal direction of the molding, and then rotated inside to insert the long side into the metal channel material a of the molding. The channel material a has a flat plate shape that can be inserted into the channel material orthogonally to the longitudinal direction of the mold
It integrally has an obliquely outward projecting piece 2 on one side facing one side edge of the body, and the width W between the other side 1' of the insertion body 1 and the outer surface of the free end of the projecting piece 2 is equal to that of the channel. It is larger than the inner width W between the side edges of material a.

Therefore, the insertion body 1 is held at a predetermined position in the channel material a by the force that causes the overhanging pieces 2 to bend inwardly within the channel material and the overhanging pieces 2 to expand outward.

This insertion body 1 has two openings 3', 3' and a bridge section 3 provided between them, and the lower surface of the bridge section 3 has an elongated groove 4 along the bridge section.

5 is a mounting body similarly molded from plastic, and metal plate B
When it is pushed into the mounting hole from the front side, it passes through the mounting hole while being deformed, and when it passes through the predetermined state, it is locked to the mounting hole irreversibly due to the restoring force. A sucker-shaped or washer-shaped seal portion 7 that tightly adheres to the surface of the metal plate around the frame for sealing, and a pair of engaging portions 8 that protrude from the surface of the seal portion 7 and engage with the bridging portion 3 of the insertion body. and a protrusion 9 protruding from the surface of the sealing part 7 so as to be located between the pair of engaging parts 8 and projecting into the groove 4 on the lower surface of the bridging part 3.

In this embodiment, the mounting part 6 is an anchor type fastener consisting of a shaft 10 hanging down from the center of the inner surface of the seal part and a pair of locking legs 11, 1m extending diagonally upward from the lower end of the shaft 10. When pushed in from the front side, the locking legs 11, 11 are deflected inwardly at the edge of the mounting hole, respectively, and the outward step 11' at the end of each locking leg 11.11 is bent separately at the edge of the mounting hole. The locking legs 11.11 then move back outwards somewhat and then step 11.
' is attached to the edge of the mounting hole and cannot be removed.

The insertion of the mounting portion 6 into the mounting hole is limited to the above state by the seal portion 7 coming into pressure contact with the surface of the metal plate around the mounting hole.

Therefore, when the mounting part 6 is mounted in the mounting hole, the sealing part 7 comes into close contact with the surface of the metal plate and airtightly seals the mounting hole.

However, the mounting part 6 is not necessarily limited to the anchor-type fastener as in this embodiment, and as described above, it is inserted into the mounting hole while being deformed from the front side and is mounted irreversibly, and the seal part 6 is attached in the mounted state. Other types of fasteners may be used as long as they provide a seal at 7.

The engaging parts 8 are opposed to each other with the protrusion 9 in between, and have hooks 8' projecting in the direction of each other at their upper ends.

The opposing surfaces of both hooks 8', 8' are sloped, and when the hooks are relatively pressed against the bridging part 3 from below, the retaining parts 8, 8 are pushed outward on the lower surface of the bridging part. Proceed through the openings 3', 3' from bottom to top, and when the hooks 8', 8' pass the top surface of the bridge section 3, the engaging sections 8, 8 return to their original positions and engage the top surface of the bridge section with the hooks. Match.

In this state, the protrusion 9 fits into the groove 4.

Note that the length L of the groove 4 is longer than the length 1 of the protrusion 9.

Furthermore, as is clear from FIG. 4, the left and right upper surfaces 12, 12 of the bridge portion with which the hook 8' of the engaging portion 8 engages are sloped to facilitate the disengagement of the insertion body 1 and the mounting body 5. In addition to leaving it as
The bridging portion is made gradually thicker from the bottom to the top, so that both sides 13, 1'3 are sloped, and when the hooks of the retaining pieces are engaged, the engaging pieces can be placed so as to gradually expand. preferable.

In order to fix the molding A on a metal plate, the molding is made to hold a required number of insertion bodies 1 at intervals corresponding to the mounting holes bored in the metal plate.

Then, engage the mounting body 5 with the retaining part 8.8 to each insertion body 1 as described above, and push the mounting part 6 of each mounting body into the mounting hole arranged in a row, or The mounting body may be mounted in each mounting hole using the mounting portion 6, and the insertion bodies held by the moldings may be pressed against the respective engaging portions of the mounting body.

In this case, as described above, the length L of the groove 4 of the insertion body is greater than the length 1 of the protrusion 9 of the attachment body, and the protrusion 9 can move in the longitudinal direction of the molding within the groove 4 by the difference. Therefore, even if the position of the insertion body held in the molding is slightly shifted in the longitudinal direction of the molding with respect to the mounting hole of the metal plate or the mounting body attached to it, this error can be absorbed and the molding can be fixed without any problem. be able to.

Even if a force is applied to the molding in the width direction when the molding is fixed, the protrusion 9 fitted in the groove 4 of the insertion body counteracts this force, so that the retaining part 8 is bent and the hook 8' is removed from the bridge part 3. prevent

Also, when it is necessary to remove the molding for repairs, painting, etc., insert a thin tool under the molding, and use the tool to pry the molding onto the metal plate, and the top surface of the bridge section will hook 8', 8'.
is pushed upward to spread out the engaging portions 8.8, so that the insertion body is removed from the mounting body.

Therefore, the molding can be removed relatively easily.

In addition, if the upper surface of the bridge part 3 is placed as the slope 12.12 as described above, this slope 12 will act as a hook to push the hooks 8', 8' upward and spread the engaging parts 8, 8 apart. This makes removal of the molding easier.

After the removed molding is repaired and painted, it can be reattached by pressing the insertion body to the engagement portion of the attachment body.

As is clear from the above, according to the present invention, the inserter 1 to be inserted and held in the molding and the body of the mount 5 to be attached to the mounting hole of the metal plate are respectively molded of plastic, and the inserter and the mount are engaged. This allows the molding to be removably fixed on the metal plate, and there is no problem even if the position of the insertion body held by the molding is slightly different from the mounting hole or the mounting body attached to the molding in the longitudinal direction of the molding. It can be installed without any trouble, and there is no need to take the trouble of accurately aligning the position of the insertion body.

In this embodiment, when the insertion body is inserted and held in the molding, the bridge portion 3 faces in the longitudinal direction of the molding, but it may be made to face in the width direction of the molding.

Further, protrusions 15 are integrally provided on the upper and lower surfaces of the insertion body 1,
When inserting into the molding, the insertion body should be inserted into the side part 1' and the overhanging piece 2.
In addition, it is preferable that the protruding portion 15 is also brought into sliding contact with the inner surface of the molding.

In particular, when a protrusion is provided at the center of the upper surface of the overpass section 3, the hooks 8', 8' of the engaging sections 8, 8 are raised above the upper surface of the overpass section in order to engage the upper surface of the overpass section 3. The space necessary for protrusion can be reliably maintained by this protrusion 15'.
