Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device used for detachably attaching a molding or the like to a window opening edge of an automobile.

[Conventional technology]

In the case where a long object such as a decorative molding or a weather strip is attached along the side edge of a plate-like object such as a panel so as to sandwich the side edge portion, it is disclosed in Japanese Utility Model Publication No. 61-21286. For example, a seal mounting device or a molding mounting device disclosed in Japanese Utility Model Publication No. Sho 61-31852 has been used.

Each of the clips for attaching seals or moldings shown in these publications has a shape to be attached to a long sealing material or molding material and a locking structure fixed to the sealing material or the like. In addition, the panel has a groove in which an upright side edge plate portion of a panel or the like is fitted, and is mounted and used so as to straddle the upright side edge plate portion of the panel or the like.

Then, the sealing material or the like attached to the upright side edge plate portion of the panel or the like is attached to the mounting clip of the sealing material or the like so that the sealing material does not come off or slip off from the mounting surface. The locking projection provided is locked in a hole formed in the surface of the panel or the like, so that the state of attachment to the panel or the like can be stably maintained.

In order to lock the mounting clip such as the sealing material to the panel or the like, a locking projection that elastically deforms is provided on a surface of the clip where the upright side edge portion of the panel or the like fits, and the panel or the like is locked. When the clip is pushed in so as to straddle the side edge plate portion, the locking projection is elastically deformed, and the locking projection elastically returns into a hole provided in a surface of a panel or the like. It was used so as to be locked.

[Problems to be solved by the invention]

However, such a conventional mounting clip such as a sealing material is strongly locked in a mounting hole of a panel or the like in a direction opposite to a fitting direction of the mounting clip, that is, in a direction in which the fitting clip is pulled out. The mounting clip has been strongly locked in the mounting hole of the panel or the like also in a direction orthogonal to the fitting direction of the mounting clip.

Therefore, the clip attached to the side plate of the panel or the like is completely fixed to the surface of the mounting panel or the like. Prepare a special tool that can be inserted into the groove of the clip where the plate part fits, and push this tool into the groove of the clip where the side edge plate part such as the panel fits, and insert it into the hole of the clip etc. It was necessary to remove the clip so that the locked projection was bent out of the hole.

However, the clip incorporated in the side edge plate portion of the panel or the like often has a sealing material or the like so as to cover the clip, and the clip incorporated in the panel or the like using the tool described above. Was extremely difficult to dismantle.

In view of this, some attempts have been made to detach the seal member or the like integrally attached to the clip in a state where the seal member or the like is directly peeled off from the surface of the panel or the like.

However, in such a method, when the sealing material or the like is removed, the sealing material or the clip portion is apt to be damaged or broken, and it is difficult to reuse these detached parts in spite of much labor required for the removal. was there.

The locking device according to the present invention can stably attach and maintain a long object such as a sealing material or a molding to a side edge of a panel or the like in consideration of the inconvenience of the conventional clip, and if necessary, An object of the present invention is to provide an easily replaceable locking tool such as a sealing material or a molding.

[Means for solving the problem]

The locking device C according to the present invention achieves the above-mentioned object, and is configured by combining the configuration of the locking device C with a plate-shaped main body 1 provided integrally, an upper locking leg 2, and a lower locking device. The stopper leg piece 3 and the elastic locking piece 4 were first directed toward the lower portion of the plate-shaped main body 1 above the plate-shaped main body 1 along one surface a of the plate-shaped main body 1. An upper locking leg 2 is provided, and the plate-shaped main body 1 is provided with a lower portion of the plate-shaped main body 1 along a surface b opposite to the surface a on which the upper locking leg 2 is provided. A lower locking leg 3 is provided facing the upper side of the main body 1, and then a separate elastic locking piece 4 is attached to the plate-shaped main body 1 from the lower side to the upper side of the plate-shaped main body 1. And the free end side of the elastic locking piece 4 protrudes toward the upper locking leg piece 2. The elastic locking piece 4 protrudes at least toward the upper locking leg piece 2. Vertical side edges in the width direction of which portions are configured as chamfer 4a.

[Action]

In the locking device C according to the present invention, one side edge of the molding M having the inverted U-shaped cross section between the plate-shaped main body 1 and the lower locking leg 3 is inserted and locked. At the same time, the other side edge of the molding M which is attached so as to straddle the locking tool C is engaged with the lower edge of the upper retaining leg piece 3 to be assembled with the molding M.

Further, a side edge plate on which the panel P rises between the plate-shaped main body 1 of the locking member C and the upper locking leg 2 while elastically bending the upper locking leg 2. The elastic locking piece 4 provided on the plate-shaped main body 1 is inserted by inserting the
Is bent toward the plate-shaped main body 1 by the side edge plate portion of the panel P, and the elastic locking piece 4 elastically returns into the hole t provided in the panel P and the locking member C Is fixed to the surface of the panel P.

In this state, when the molding M attached to the surface of the panel P is pulled in a direction opposite to the direction of the fitting,
Elastic locking piece 4 of locking tool C attached to this molding
Is engaged with the edge of the hole t of the panel P, and the molding M is prevented from coming off from the panel P.

Next, the molding M attached to the surface of the panel P
Is pulled in a direction perpendicular to the fitting direction,
The elastic locking piece 4 of the locking tool C attached to the molding M has its chamfered surface 4a in contact with the edge of the hole t of the panel P, and the molding M is further pulled. Hole t
The surface 4a rides on the edge of the hole, and finally the elastic locking piece 4 completely comes out of the hole t, and the panel P of the locking tool C
The locked state with respect to is lost.

In this state, the molding M can be removed from the panel P by pulling the molding M in a direction opposite to the fitting direction.
