Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a ninth attachment structure for attaching a soft member, particularly a resin bumper, to a vehicle body.

[Conventional technology]

Conventionally, as shown in FIG. 3, for example, a box portion 2t is formed on the back surface of a synthetic resin bumper 1 and is combined with a bracket 3, and the bumper +++1 is attached via a mounting pole 3a. It has a structure that screws onto the mounting part of the vehicle body etc. with a nut.

The box part 2 is formed on the back surface of the bumper 1, and has a flange fitting groove 2a into which the mounting flange 3b of the bracket 3 fits.
A drop-off prevention claw 2c is formed on the top flat part of the box part 2 and forms a narrow passage continuous with the T-port insertion hole 2b and the bolt insertion hole 2b.

On the other hand, the bracket 3 has a dust-covered flange 3b that fits into the flange fitting groove 2a, and a mounting bolt 3a erected approximately in the center, which is fitted into the bolt insertion hole.

In addition, as a structure different from the above, when molding the entire bumper 1 with bolts, the mounting part is molded by setting it in a mold and molding at the same time, that is, by insert molding.

[Problem that the invention seeks to solve]

In the case of the mounting structure shown in Figure 3, if it is molded from a hard resin such as polypropylene, there is no problem; however, if it is molded from soft rubber or thermoplastic rubber, the direction of insertion of the bracket and the base Even if the fixing directions of the brackets do not match, there is a risk that the bracket will fall off from the box part, and it may not function as a mounting part.

Further, in the case of the insert molding, when applied to an exterior product such as a bumper, sink marks and the like occur on the outer surface, causing a significant deterioration in appearance quality.

Furthermore, the mold for insert molding has the disadvantage that it is more complicated than that for molding the attachment part of the box part mold.

Therefore, the present invention prevents deterioration of appearance quality, and
Even with soft materials, the mounting bracket can be connected securely.
Moreover, the object is to provide a complete structure of the mounting part that can be molded with a simple mold structure.

[Measures for resolving obstacles]

The flange of the mounting bracket is inserted into the insertion groove of the box portion formed of a soft member, and the fixing flange of the mounting bracket is formed of the soft member and fixed to the stop portion.

〔Example〕

An embodiment of the present invention will be explained with reference to FIGS. 1 and 2.

The figure shows the entire artificial surface of the bumper 8 made of soft synthetic resin such as heat 5] 1m rubber (T, P, R). Insert #It4&t- while forming a box part with
A screw stopper part 6 which can be fastened with a screw screw 7 is constructed at a location different from the box part.

The mounting bracket 5 has a locking flange 5b't on the base 5a.
- forming a locking flange insertion groove 4a of the box portion 4;
It is preferable to form the t0 locking flange 5b on both left and right sides of the fixing flange 5d so that K inserts and locks, and secure fixation is possible.

The base portion 5aK is integrally formed with an extension portion 5ct that connects with the fixing flange 5d, and is connected to a screw stopper 6 formed on the back surface of the bumper 4 by a fixing device 71C such as a screw through a through hole 5f formed in the fixing flange 5d. Let's stick together.

〔Effect of the invention〕

As explained above, this invention has the following configuration, and since the fixing part of the bracket is formed separately from the direction in which the bracket is inserted and locked, the direction in which the vehicle body is fixed and the direction in which the bracket is fixed (sliding direction) are different, and it is difficult to attach to the soft member. Even if the mounting structure of the present invention is applied, the bracket will not be removed from the box part and will not fall.9. Furthermore, the fixing part and hardening part of the bracket are clearly designed to improve the mounting strength of the mounting part.

The mold structure is not so complicated compared to the conventional box mounting structure, and unlike insert molding, there are no sink marks on the outer surface and there is no deterioration in appearance quality. There are advantages.
