[Detailed description of the invention]

[0001]

This invention is based on means for attaching other members to a plate-like surface of a panel or the like, in particular, by using a clip which is inserted and locked in a mounting hole provided in the plate-like surface of a panel or the like. The present invention also relates to the provision of a clip used to lock another member end to the plate-like surface.

[0002]

2. Description of the Related Art In the case where another member having a relatively soft mounting end is assembled and fastened to a so-called plate-shaped surface such as fastening a kick plate made of plastic to a body panel of an automobile, Clips as shown in FIG. 8 were commonly used.

In this type of clip, an outward flange 1 is provided at an opening edge of a synthetic resin clip cylinder A so as to be inserted and locked in a mounting hole H of a plate-like material P such as a body panel. An elastic locking piece for holding the hole edge of the mounting hole H with the flange 1 is provided on the outer periphery of the clip cylinder A, and the clip cylinder A inserted into the mounting hole H is assembled to the plate-like object P. The mounting end S 'of the mounting object S such as a kicking plate is fixed to a metal stopper member B assembled in the clip cylinder A.
In particular, the metal stopper member B has a pair of side pieces 3 and 3 formed in a U-shape so that the mounting end S ′ of the object S can be inserted and locked between the stopper members B.
Are held in the clip cylinder A in a state where they are opposed to each other, and an elastically deformable locking projection 5 that fits below the projection 4 provided on the inner wall of the clip cylinder A is provided. The stopper member B housed in the clip cylindrical body A has a configuration in which the stopper member B has an outwardly projecting state and further has a check pawl 6 so as to project between the side pieces 3. The locking projection 5 is pressed against the projection 4 on the inner wall of the clip cylinder A to prevent the clip projection A from slipping out of the clip cylinder A, and to prevent the clipping piece 5 from being inserted between the opposing side pieces 3, 3. The check claw 6 bites the mounting end S ′ of the mounting object S.

[0004]

However, in such a clip, the convex portion 4 provided on the clip cylinder A is provided.
Does not have a sufficient protruding height, the stopper member against the convex portion 4 can be subjected to slight elastic deformation toward the mutually constricted side of the side pieces 3, 3 of the stopper member B locked thereto. B, the locking state of the locking projection 5 is lost, and the stopper member B has a disadvantage that it comes out of the clip cylinder A together with the attachment S attached to the stopper member B.

[0005] In the case where the protrusion 4 provided on the clip cylinder A can be provided with a sufficient protruding height from such a point, the engagement of the stopper member B housed in the clip cylinder A can be improved. The stopper convex portion 5 is securely locked by the convex portion 4 of the clip cylinder A, so that the mounting member S can be attached even when a strong pulling force is applied to the mounting member S mounted on the stopper member B. Although the object S has a feature of being stably held by the clip, it has a disadvantage that the stopper member B or the attached object S once assembled cannot be easily removed from the clip cylinder A.

When the projection 4 of the clip cylinder A is designed to have a sufficient protruding height, the resin molding of the projection 4 may be performed on the opening side and the bottom side of the clip cylinder A, or on the opening side. It is necessary to remove the mold from at least two directions, that is, the side and the peripheral side, and the molding die becomes complicated, and a large amount of molding time is required. Further, in the die-cutting molding of such a clip cylinder A, a hole Y for die-cutting is inevitably provided in the cylinder part of the clip cylinder A inserted and locked in the plate-shaped material P, There was difficulty in locking the attached object S to the plate-shaped object P in a water-tight or air-tight manner.

[0007] In view of the disadvantages of the conventional clip, the present invention makes it possible to water-tightly and air-tightly mount an object S to be attached to a plate-like object P such as a panel. It is an object of the present invention to provide a low-cost clip that can detach the attached stopper member B and the object S attached to the stopper member B.

[0008]

A clip according to the present invention comprises a plastic clip cylinder A and a metal stopper member B incorporated in the clip cylinder A to achieve the above object. The clip cylinder A is configured such that an upper end is open and a bottom portion having an outward flange 1 on the open edge is closed at a bottom. The metal stopper member B to be incorporated in the first embodiment is configured to have a pair of side pieces 3 and 3 that are open at least at the upper end and that are spaced apart from each other. Next, each side piece 3, 3 of the stopper member B is provided with a check pawl 6 projecting between the side pieces 3, 3, and the clip on the side opposite to the protruding side of this check claw 6 is provided. A locking projection 5 that locks to the projection 4 that is raised on the inner wall of the cylindrical body A is provided in a protruding state. Further, on the outer periphery of the clip cylinder A, there is provided an elastic locking piece 2 which clamps the hole edge of the mounting hole H of the plate-shaped material P between the clip 1 and the flange 1.
Further, on the outer periphery of the clip cylinder A between the convex portion 4 and the flange 1, a position in contact with the hole edge of the mounting hole H is a raised portion 7, and the position including the raised portion 7 is included. The peripheral wall of the clip cylinder A is configured to be elastically deformable.

[0009]

[Function] The clip according to the present invention has a distinctive feature described above,
In particular, since the plastic clip cylinder A constituting the clip is configured to be closed at the bottom, the plate-like material P
There is no leakage of rainwater or the like from the side of the mounted object S attached to the plate member P, and the mounting hole H in the plate-shaped object P functions to be closed in a water-tight and air-tight manner.

A portion between the convex portion 4 of the clip cylinder A and the flange 1 and in contact with the hole edge of the mounting hole H is a raised portion 7 and includes the raised portion 7. Since the peripheral wall of the clip cylinder is provided so as to be elastically deformable, at least the upper part of the convex portion 4 of the clip cylinder A inserted into the mounting hole H of the plate-like object P is deformed to the side where it is narrowed to each other, It functions to prevent the stopper member B, which is accommodated below the convex portion 4, from coming off.

Further, the raised portion 7 of the clip cylinder A elastically deformed toward the side narrowed by the hole edge of the mounting hole H of the plate-like object P releases the pressing force against the raised portion 7. As a result, the clip cylinder A returns to the old position together with the projections 4 that are pressed and deformed toward the mutually constricted sides, and the elastic deformation function of the peripheral wall portion of the clip cylinder A including the protruding portion 7 causes the inside of the clip cylinder A to move. The stopper member B and the member S to be mounted incorporated in the first member are detached from each other.
