Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a bag-shaped member with a locking claw, and more specifically, to a bag-shaped member with a locking claw, for example, a bag-shaped member that fits into a mounting stud protruding from the body of an automobile or the like. This invention relates to a bag-shaped member made of synthetic resin with a locking claw, such as a clip for attaching a weather strip (or molding) or a footrest for an automobile.

[Conventional technology]

As a conventional bag-shaped member with a locking claw,
For example, there is a clip 1 for attaching a weather strip shown in FIG. As shown in FIGS. 10 and 11, this clip 1 is formed in the shape of a hollow bag with an open bottom, and the hollow portion has a predetermined shape and a protrusion extending laterally to the opening direction. A pair of locking claws 2 having a width are protruded. An outward flange 3 is provided along the outer periphery of the opening of the clip 1, and a pair of positioning protrusions 4 are provided at predetermined positions on the lower surface of the flange 3.
is formed.

As shown in FIG. 11, when fixing the weather strip 6 attached to the body 5 of an automobile, etc., the weather strip 6 can be fixed with a clip using the protrusion 4 and the positioning hole (not shown) of the weather strip 6. 1, fit the bag-shaped hollow part of the clip 1 into the stud 7 protruding from the body 5,
The locking pawl 2 is locked to the collar 8 of the stud 7, and the locking force is used to press and fix the weather strip 6 to the body 5 side by the flange 3.

[Problem that the invention attempts to solve]

However, when fitting the clip 1 to the stud 7, the flange 8 of the stud 7 is engaged because the locking pawl 2 protrudes sideways with respect to the opening direction of the clip 1, which is the fitting direction of the stud 7. The retaining claw 2 is forced into the retaining claw 2 while being forced outward, and in this process, the tip of the synthetic resin retaining claw 2 is often shaved off into a round shape, as shown in FIG. For this reason, the locking pawl 2 cannot maintain the protrusion width h (see FIG. 12) and the approximately triangular cross-sectional shape necessary for effectively locking the flange 8. There was a problem that 1 could easily come off the stud 7.

Note that if the locking pawl 2 of the clip 1 is made larger than planned, the protrusion width necessary for fitting the stud 7 can be obtained, but simply increasing the protrusion width of the locking pawl 2 will not allow the stud to fit. This has the disadvantage that it becomes difficult to attach the bag-shaped member. In addition, the locking claw 2
Since the portion to be shaved is roughly limited, simply increasing the protrusion width of the locking pawl 2 is not effective.

Therefore, the present invention provides that when a bag-shaped member with a locking pawl is fitted into a mounting stud with a flange, even if the tip of the locking pawl is scraped off by the flange, The technical problem to be solved is to maintain the protrusion width and cross-sectional shape that can be effectively locked.

[Means for solving problems]

The technical means for solving the above problems includes a bag-shaped hollow part that protrudes from the body of an automobile or the like and can fit into a mounting stud having a flange on the tip side, and a predetermined part of the hollow part. A bag-shaped member made of synthetic resin has a pair of locking claws that can be locked to the flange of the stud protruding horizontally with respect to the fitting direction of the stud, on both sides of the stud. The retaining claw includes an effective claw portion having a protruding width and a cross-sectional shape that can be effectively engaged with the flange of the stud, and a scraping claw portion adjacent to the effective claw portion and having a larger protruding width than the effective claw portion. They were each formed by the following.

In the above technical means, the bag-shaped member is not limited to a mounting clip such as a weather strip or molding, but also includes, for example, a box-shaped stud-fitting footrest with an open bottom, and various other bag-shaped members. include.

The stud may be any stud that protrudes from the body of an automobile or the like and has a flange protruding from the tip side. Examples include T-shaped studs, so-called stud bolts with heads, or screws fixed to the body. The material of the stud may be any material that has a predetermined hardness and can be molded, such as metal or synthetic resin.

[Effect]

When fitting the bag-shaped member to the mounting stud, the flange of the stud is pressed into contact with the sharpening claw part of the locking claw that protrudes widely, and the cutting claw part is press-fitted while prying the entire bag-shaped member outward. be done.

During press-fitting, the tips of the scraping pawls are rounded off, but this prevents the effective pawls from being scraped off and maintains a predetermined protrusion width and cross-sectional shape.

〔Example〕

Next, an embodiment of the present invention will be described based on FIGS. 1 to 8.

As shown in Figures 1 and 2, the clip 9 made of synthetic resin has a hollow square shape in the center, rectangular in this example, and an open bottom (lower part in Figure 1). Bag-shaped stud fitting part 10
It is equipped with A pair of flat board parts 11 extend from the lower part of the stud fitting part 10 in the left and right directions, and are slightly inclined downward along the lower part of the stud fitting part 10 and the peripheral edge of the board part 11. An outward facing flange 12 is formed.

Inside the stud fitting part 10, from predetermined positions corresponding to each other on a pair of side walls 13 along the longitudinal direction, a pair of opposing locking claws protrude laterally with respect to the opening direction of the stud fitting part 10. 14, and a thick wall portion 16 is formed on the back side of the locking pawl 14, that is, between the locking pawl 14 and the top plate portion 15 of the stud fitting portion 10.

As shown in FIGS. 3 and 4, the locking pawl 14 has a pawl width W necessary for locking with a stud 17 (see FIG. 5), which will be described later. It consists of a scraping claw part 14a formed at the top and effective claw parts 14b integrally formed on both sides of the scraping claw part 14a. Effective claw portion 14b
In order to obtain an effective locking force with the stud 17, as shown in FIG. It is formed. Further, the scraping claw portion 14a is formed to have a protrusion width h2 larger by a predetermined amount than the effective claw portion 14b.

Furthermore, as shown in FIG.
is provided.

This embodiment is constructed as described above and is used as follows.

That is, as shown in FIG. 5, a mounting stud 17 having an oblong flange 20 projecting in the radial direction is provided on a body 19 of an automobile or the like,
On this body 19, there is an insertion hole 2 for the stud 17.
Overlay the weather strip 22 with the weather strip 1. Then, attach the clip 9 to the stud 17 that protrudes upward from the weather strip 22 from the insertion hole 21.
The stud fitting portion 10 is fitted. At this time, the clip 9 is positioned with respect to the stud 17 by aligning the pair of alignment holes 23 provided in the weather strip 22 with both of the protrusions 18.

When the stud fitting part 10 is fitted to the stud 17 in this way, the locking pawl 14 that protrudes laterally to the opening direction of the stud fitting part 10, which is the fitting direction of the stud 17, is attached to the collar part 20 of the stud 17. Because of interference, as shown in FIG. 6, both locking claws 14
is forced outward by the collar 20 and press-fitted into the stud 17.

However, what is pressed against the flange 20 at this time is
Among the locking claws 14, the scraping claw portion 14 with a large protrusion width
Therefore, the tip of the scraping claw portion 14a is rounded off as shown in FIG. 7, but this prevents the effective claw portion 14b from coming into contact with the collar portion 20.

Therefore, even after the clip 9 is attached to the stud 17, the effective claw portion 14b maintains the cross-sectional shape and protrusion width that allow it to effectively engage the flange portion 20, so that the clip 9 is not attached to the stud 17. It is effectively locked and fully performs the function of fixing the weather strip 22 to the body 19 side.

In the above embodiment, the locking pawl provided on the clip may have an effective pawl portion at the center in the width direction and a scraping pawl portion on both sides (not shown). In addition, as shown in FIG.
When the flange portion 20 is circular, it is preferable that the cutting claw portions 14a and the effective claw portions 14b of the locking claw 14 have their respective tips arranged in an arc shape.

[Effect of idea]

The present invention maintains the protruding width and cross-sectional shape of the locking pawl that can be effectively locked to the flange when fitting the bag-shaped member with the locking pawl to a mounting stud equipped with a flange. be able to.

Therefore, the bag-shaped member with the locking claw can be prevented from coming off the stud, and the bag-shaped member with the locking claw can be sufficiently fitted to the stud.
