[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal holder used for fixing a mounted member (for example, a dash panel of an automobile) to a fixing member (body).

[0002]

2. Description of the Related Art Conventionally, when a dash panel of an automobile is fixed to a body side, a metal holder is mounted on the dash panel side in advance, and a tip end of the holder is fixed to a fixing hole on the body side. To secure the entire body. Specifically, as shown in FIG. 7, a mounting boss 34 protrudes from a part of the dash panel 30 (made of synthetic resin), and the holder 32 is mounted here. On the other hand, the holder 32 is formed by integrally bending a thin metal plate, and is provided with an engaging portion 35 which is inserted into a fixing hole 33 on the body 31 side in a state of being prevented from falling off. ing. The engaging portion 35 has a substantially barbed shape as a whole, and both upper and lower pieces are bent and deformed to be elastically engaged with the fixing holes 33. The rear portion of the holder 32 is provided with a mounting boss 34 of the dash panel 30.
The holding portion 36 is fitted into the holding portion 36. The holding portion 36 is formed by bending both side edges of the holder 32 inwardly to form a substantially C-shaped section.
A pair of locking claws 37 is formed at a part of the opening edge thereof, and is prevented from falling off by being cut into the upper surface of the mounting boss portion 34.

[0003]

As described above, since the conventional holder 32 is formed by fitting the holding portion 36 to the outer shape of the mounting boss portion 34 and merely holding it by being fitted, If there is a processing error in any of the fitting side and the height (thickness) dimension of the fitting side, rattling easily occurs. That is, the conventional holder 32 cannot absorb such a processing error, and this causes rattling after the dash panel 30 is assembled.

The material of the dash panel 30, including the mounting boss 34, related to the fixing to the body 31 is made of a synthetic resin as described above or of a metal, and The proper use is made according to the method. In this case, the thickness of the mounting boss portion 34 of the metal member is greater than that of the resin member. Therefore, the internal height (H dimension shown in FIG. 8) of the holding portion 36 is also set accordingly, but the dimension setting is currently limited to about 2 mm, and processing is performed below this. Not easy. For this reason, the conventional one cannot sufficiently cope with the thin mounting boss part 34, and as described above, it causes rattling.

The present invention has been devised in view of such conventional problems, and an object of the present invention is to provide a holder which can fix an object to be mounted without play.

[0006]

In order to achieve the above object, the structure of the present invention relates to a fixing member which is mounted on a thin plate-like mounting boss protruding from a part of a member to be mounted. The holding member for fixing the mounted member to the fixed member side by being combined, an engaging portion integrally formed of a thin plate made of spring steel and capable of engaging with the fixed member, and the mounting boss portion. And a flexure piece which can be elastically contacted with the mounting boss portion, and a hole formed in the mounting boss portion separately and independently from the mounting boss portion. Alternatively, a retaining claw for preventing the mounting boss from being detached in a direction opposite to the external fitting direction by being elastically hooked on the step portion is provided.

[0007]

[Action]

When the holding portion of the holder is fitted into the mounting boss of the object to be mounted, the bending piece is bent and deformed and comes into contact with the mounting boss with elasticity. In this state, if the engaging portion of the holder is engaged with the fixing member, the mounted object is assembled to the fixing member.

[Effects of the Invention] The effects of the present invention are as follows. In a state in which the holding portion is fitted into the mounting boss portion, the bending piece elastically contacts the upper surface of the boss portion, thereby absorbing a processing error between the boss portion and the holding portion and securing the close contact between the two. . Thereby, while being able to cope with the thin boss portion, the play between the holder and the mounted member is eliminated, and the mounted member can be assembled to the fixed member without play.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; FIGS. 1 to 4 show a first embodiment of the present invention, and FIG. 1 shows a related portion for fixing a dash panel (mounted member) 1 of an automobile to a body 2 side. One side is made of a thin metal plate. A mounting boss portion 4 for mounting the holder 3 is integrally formed on a part of the mounting boss portion 4 so as to protrude left and right through a stepped surface 5, and a through hole 6 is opened in the center of the mounting boss portion 4. I have.

The holder 3 is formed by bending a thin plate made of spring steel, and is disposed at the front of the holder 3 for fixing to the body 2 side, and at the rear of the holder 3. It is formed integrally with the holding portion 8 which is disposed and fixed to the dash panel 1 side.

As in the prior art, the engaging portion 7 has a generally barbed shape as a whole, and includes a pair of locking pieces 9a and 9b projecting up and down in the figure and having different widths.
In FIG. 1, the upper locking piece 9a is formed by folding the front edge of the holder 3 with an upward slope, and has locking edges 10a and 10b bent obliquely downward at the leading edge. On the other hand, the lower locking piece 9b is formed by cutting and raising while leaving both side edges of the holder 3 substantially the same width, and in this case, the lower locking piece 9b is formed by the upper locking piece. 9a, it is bent substantially in common with the folded edge, and is projected so as to have a substantially symmetrical gradient with the upper locking piece 9a. Similarly, a locking edge 10b is formed symmetrically bent at the tip. I have. The engaging portion 7 thus formed
In addition to the above, a good flexibility is provided so that both locking pieces 9a and 9b can pass through the mounting hole 11 on the body 2 side, and both locking edges 10a and b are elastically attached to the hole edge of the mounting hole 11. Engagement can be prevented from falling off.

A mounting boss 4 is provided on the rear side of the holder 3.
A holding portion 8 for attachment to the vehicle is provided. The holding portion 8 can almost match the outer shape of the mounting boss portion 4,
The both side edges of the holder 3 are bent symmetrically so that the vertical cross section is substantially C-shaped, and the opening at the rear end face becomes the insertion port 12 to the mounting boss 4. . Further, as shown in FIG. 2, both opening edges facing each other in the holding portion 8 are formed to be curved inward and along the entire edge to form a bending piece 13 which can elastically contact the mounting boss portion 4. However, when both flexures 13 are in a free state, the height from the bottom surface of the holding portion 8 to the tip of both flexures 13 is set appropriately smaller than the thickness of the mounting boss 4.

Further, a rear end portion of the holding portion 8 (insertion port 1)
An inwardly tapered surface is formed on the two bent pieces 13 so as to reach the two bending pieces 13 so that the fitting operation to the mounting boss 4 can be performed smoothly (see FIG. 3). . Furthermore, a retaining claw 14 is formed by cutting and raising the bottom surface of the holding portion 8, and can be engaged with the through hole 6 of the mounting boss portion 4.

Next, the operation and effect of the holder of the present embodiment configured as described above will be specifically described. First, the work of attaching the holder 3 to the attachment boss 4 is performed. In this case, the mounting boss 4 is fitted and inserted into the insertion opening 12 of the holding portion 8, but even if there is a deviation in the height direction, the insertion operation is guided by the tapered surface 15, so that the operation can be performed smoothly. Can be. Further, the insertion operation is performed while bending the both bending pieces 13. Then, if the opening edge of the insertion opening 12 is pushed until it contacts the two step surfaces 5 on the dash panel 1 side, the retaining claw 1
4 is engaged with the through hole 6 to complete the mounting of the holder 3 on the mounting boss 4.

Thereafter, when the engaging portion 7 of the holder 3 is pushed in so as to fit the mounting hole 11 of the body 2,
A and b pass through the mounting hole 11 while flexing and deforming, and after passing through, elastically return, the locking edges 10 a and b engage with the mounting hole 11. As a result, the retainer 3 is prevented from falling out of the body 2, so that the fixing of the dash panel 1 to the body 2 is completed.

As described above, according to the holder 3 of the present embodiment, the elasticity of the flexible piece 13 is used to make contact with the mounting boss 4 so that the thickness of the mounting boss 4 or the holding portion 8 can be improved. Even if there is a variation in the internal height of the head, this can be effectively absorbed to enable the rattle-free holding. Therefore, it is possible to enhance the reliability of mounting the dash panel 1. In addition, since the internal height of the holding portion 8 does not necessarily have to be strictly set in accordance with the thickness of the mounting boss portion 4, the bending process of the holder 3 is facilitated and the thin mounting boss portion 4 is formed. Can respond. Furthermore, since the insertion operation to the mounting boss portion 4 is guided by the tapered surface 15 of the holding portion 8, an effect that the insertion operation can be smoothly performed even in the insertion opening 12 having an extremely small insertion area is obtained.

FIG. 5 shows a second embodiment of the present invention. In this embodiment, the boss 4 is attached to the bottom of the holding portion 8.
The bulging portion 16 for receiving the bulge is formed along the length direction. The reason why the bulging portion 16 having the predetermined height is formed as described below is that the height distance between the linear portions on both side surfaces of the holding portion 8 is secured longer, and the mounting boss portion 4 is formed. This is because the play in the lateral direction can be restricted.

That is, as shown in FIG. 8, the holding portion 8 needs to be bent with a predetermined curvature R at each corner, and if it is bent at a right angle, a crack is generated. Therefore, in the case of the holding portion 8 in which the internal height cannot be sufficiently secured to cope with the thin mounting boss portion, the R surface set at each corner as described above causes the holding surface 8 on both sides of the holding portion 8 to be formed. The length of the straight portion (a portion for receiving both side edges of the mounting boss portion 4) cannot be sufficiently secured.

However, by forming the bulging portion 16 on the bottom surface of the holding portion 8, the vertical play with respect to the mounting boss portion 4 is regulated, so that the height distance between the linear portions on both side surfaces is secured. As a result, rattling in both the left and right directions can be reduced.

The other structure is the same as that of the first embodiment, so that the same operation and effect can be exhibited.

FIG. 6 shows a third embodiment of the present invention. In this embodiment, locking steps are provided on both side surfaces of the mounting boss 4 as means for preventing the holder 3 from coming off the mounting boss 4. 17, a pair of retaining claws 18 engageable with these are cut and raised on both sides of the holding portion 8 on the holder side. Others are the same as the first and second embodiments.
