[Prior Art]

 As in the case of mounting a side protector molding on the surface of an automobile body panel, a trough-shaped first member B (a molding in the illustrated example) having a pair of facing engaging grooves 20, 20 and an engaging hole. When assembling with the plate-shaped second member C having H (the body panel of the automobile in the illustrated example), clips A ′ as shown in FIGS. 9 and 10 are used in each direction.

This kind of clip A ′ is twisted in the trough portion of the first member B, and the short side of the pair of engaging grooves 20 and 20 in the first member B. It is composed of a rectangular head portion 1 into which the edge portions 1a, 1a are pushed and locked, and a leg portion 2 projecting integrally from the head portion 1. A pair of elastic locking pieces 3, 3 extending from the tips of the legs 2 toward the head 1 side are provided so as to gradually widen between the respective free ends. The hole edge h 1 of the engaging hole H of the second member C is held between the head 1 and the head 1. Further, the head 1 has a shape in which it is tightly fitted in the engagement groove 20, 20 of the first member B in a twisted state, and the leg 2 is covered with the soft resin material K. There is. Further, a part of the surface of the head 1 which is continuous with the legs 2 is covered with the soft resin material K, and the peripheral edge of the soft resin material K covering the surface of the head 1 is covered by the head. It is configured as a flange portion 4 which is erected from the surface of the portion 1 toward the circumferential side of the head portion 1 in an inclined manner.

The clip A ′ having such a configuration has a gutter shape between the engagement grooves 20 and 20 in a state where the long side edge portion 1b is along the engagement groove 20 of the first member B. The clip A ′ in the trough-shaped portion and twisting the clip A ′ in the state where the clip A ′ is accommodated in the gutter-shaped portion, so that the short side edge 1a of the head 1 of the clip A ′ is engaged with the engaging groove. Assemble by pressing firmly into the inside of 20, 20, and then put the assembled first member B of this clip A'onto the second member C and attach the leg 2 of the clip A'to the second. The first member B and the second member C are used by being inserted and locked in the engaging hole H in the member C to be assembled.

The clip A ′ having such a structure is assembled in a state of being hidden on the mounting surface side of the first member, and is assembled at an arbitrary position of the engaging groove 20 of the first member B. Since it can be attached and can be moved along this engaging groove 20, it was suitable for attaching decorative materials such as side protector moldings to the decorative surface such as the outer surface of the body panel of the automobile. .. Especially, when high makeup characteristics are required for assembling the members and the engaging holes for assembling are previously provided on the assembling decorative surface, the engaging holes can be securely and reasonably clipped. In order to insert and lock the leg portion 2 of A ′, it is necessary that the clip A ′ can be assembled or moved and assembled to the first member B at any time and any position. It is usually preferable that the leg portion 2 has a configuration in which the portion 2 does not damage the surface of the second member C and the hole edge h of the engagement hole H. These conditions are not included in the clip A ′. The gap was also satisfactory. Further, the engaging hole H in the second member C provided for assembling the first member B is surely sealed by the flange 4 made of the soft resin material K, and it is possible to ensure the high sealing performance. It was made possible to assemble the first member B to the second member C.

[0006]

[Problems to be solved by the device]

 However, in such a conventional clip A ′, the short side edge portion 1b on the head 1 of the clip A ′ assembled to the first member B is not covered with the soft resin material K, and this short length is short. Since the side edge portion 1b is a molding surface of a hard and low-slip synthetic resin molding forming the main body of the clip A, the engaging grooves of the first member B facing each other. The head 1 of the clip A ′, which is strongly pushed and locked between 20 and 20, moves along the engaging groove 20 or loosens to the untwist side. As a result, a plurality of clips A ′ are attached to the first member B in advance, and the legs 2 of the clip A ′ are sequentially attached to the second member C with the clips A ′ attached to the second member C. At the time of assembling work such as inserting into the engaging hole H, the mounting clip A ′ is apt to be displaced or misaligned, so that the members cannot be assembled with each other. Also, without assembling the two members C, the legs 2 of the clip A'of the first member B are not positioned in the engaging holes H of the second member C, and the assembling of both members is not particularly performed. In this case, the mounting surface of the second member or the mounting surface of the clip A ′ of the first member may be deformed, and the plating film on the peripheral edge of the engaging hole H may be damaged. There was an inconvenience of causing rusting on the second member.

From this point, as shown in FIG. 10, after the clip A ′ is assembled in a twisted state with respect to the first member B, the short side edge 1a of the clip A ′ is attached. The metal openings 20a of the engaging grooves 20, 20 on both sides are caulked 20b, and the clip A'assembled by the caulking 20b is moved along the groove direction and loosened toward the untwisted side. Attempts were made to suppress the and. When the caulking 20b is applied to the first member B to which the clip A'is assembled in this way, the front surface of the first member B, which is the decorative surface, is swollen by the caulking 20b. However, there is a disadvantage that the first member B does not function as a decorative material because the cosmetic properties of the first member B are significantly impaired.

Further, in the above-mentioned clip A ′, assembling with the second member C is buffered by the soft resin material K and the flange 4 made of the soft resin material K on the leg portion 2. Since the assembling of the first member B to the member B was simply by pushing the short side edges 1a of the head 1 into the engaging grooves 20, 20 facing each other, the first member assembled to the clip A ' There was a problem that a chattering noise was generated between the member B and the member B.

In view of the inconvenience of such a conventional mounting clip, in particular, a molding clip, the present invention allows the first member B to be simply twisted into the engaging grooves 20, 20. Is securely locked by the first member B, the mounting posture is stably maintained continuously, and there is no chattering during vibration between the first member B and the first member B to be mounted. The purpose is to provide a clip suitable for easy and accurate assembly with the second member C.

[0010]
