Description

[Detailed description of the invention] Industrial field of application This invention is for fixing a bag-shaped or tube-shaped member made of a soft material (hereinafter referred to as the "soft part") to a structural member made of a hard material (hereinafter referred to as the "hard member"). This invention relates to a fastening device for

Conventional Technology Clip-shaped clips are conventionally used to fix soft materials such as weather strips used on automobile doors and sealing materials used in refrigerators and heat-insulating containers to hard materials such as the main bodies of automobiles and refrigerators. A fastening member is often used. In addition, after inserting the head of the above-mentioned fastening member into a hole previously provided in the soft member,
The soft member is fixed to the hard member by press-fitting the locking part of the fastening member into the hole on the hard member side, but the head of the fastening member is more likely to come off than the soft member due to the widening of the hole. There are drawbacks.

Problems to be Solved by the Invention In order to improve the above drawbacks, the hole on the soft member side can be made smaller and the head of the fastening member can be press-fitted into this hole. There is a problem that it takes a lot of time to insert the parts, resulting in poor work efficiency.

This invention was made for the purpose of improving the above-mentioned problems.

Means and Effects for Solving Problems A locking portion that can be press-fitted into a locking hole opened in a hard member is provided on one end of the main body, and a hook-shaped locking portion that can be inserted into a soft member is provided on the other end of the main body. A fastening device that allows a soft member to be attached to a hard member without providing a hole in the soft member.

Embodiment An embodiment of this invention will be described in detail with reference to the drawings. In the figure, 1 is a shaft-shaped main body molded from synthetic resin, etc., and a conical locking portion 1a is formed on one end side. . As shown in FIG. 5, the locking portion 1a has a thinner wall on the outer peripheral side, so that it can be easily press-fitted into a locking hole 2a opened in a hard member 2, which will be described later.

Further, a hook-shaped locking portion 1b is formed on the other end side of the main body 1. The hook-shaped locking portion 1b has a horizontal portion 1c bent at right angles to the main body 1, and one end is connected to the tip of the horizontal portion 1c, and is formed into an arc approximately centered on the locking portion 1a. arched part 1
d, and a sharp pointed part 1e is formed at the tip of the arched part 1d, so that it can be easily inserted into the soft member 3.

Next, to explain the function of attaching the soft member 3 to the hard member 2, first, the tip of the hook-shaped locking part 1b is inserted from the outside of the tube-shaped soft member 3 as shown in FIG. 6a. are locked as shown in Figure 6d. Next, align and push the conical locking portion 1a of the main body 1 into the locking hole 2a of the hard member 2 as shown in FIG. 6d, and lock the conical locking portion 1a as shown in FIG. 6e. Bye.

Effects of the invention As detailed above, this invention allows the hook-shaped locking part to be attached to a soft member simply by inserting the hook-shaped locking part into the hard member and rotating the main body around the locking part. Since it can be locked, there is no need to make a hole in the soft member in advance, which allows it to be installed at any position on the soft member, and there is no need to drill holes on the soft member side, reducing man-hours. It will also be possible to reduce this.

Also, once the hook-shaped locking part is inserted into the soft member,
Since the tips of the horizontal portion and the arcuate portion are locked inside the soft member and do not easily come off even if a large force is applied, the soft member can be reliably attached to the hard member or the like.

Moreover, it can be easily mass-produced by molding synthetic resin, etc., and therefore can be provided at low cost.

[Brief explanation of the drawing]
