Description

[Detailed Description of the Invention] Technical Field The present invention is a fixing device that integrally fixes and holds a guide rail for guiding a sunroof movably arranged on the roof of a vehicle body. A holding member made of a plate material having a bottom wall, a pair of side walls that stand up integrally from each side end of the bottom wall and face each other, and a presser claw integrally connected to the upper end of each side wall; The present invention relates to a fixing device that includes a bolt and a nut for fixing a holding member to a vehicle body, holds a guide rail inside the holding member, and fixes it to the holding member using a presser claw.

2. Prior Art It is well known that a guide rail for guiding a sunroof of an automobile is fixedly held on the vehicle body by the above-mentioned type of fixing device, and FIGS. 5 and 6 show examples of the prior art.

Holding member 1a of fixing device 15a shown here
These include a bottom wall 4a, a pair of side walls 5a, 5a rising integrally from each side end thereof and facing each other, and a presser claw 6 integrally connected to the upper end of each side wall 5a, 5a.
a and 6a, and the entire structure is made of a thin plate material formed in a substantially U-shape. Holding member 1
The bottom wall 4a of a is fixed to the vehicle body 3 by a bolt 7a and a nut 8a screwed thereto,
A guide rail 2 for guiding the sunroof is then inserted into the holding member 1a. At this time, the presser claws 6a, 6a are usually raised as shown by broken lines in FIG. It is inserted into the holding member 1a while being pushed in a direction perpendicular to the paper surface of FIG. Holding member 1a
The latter direction is often adopted when the rail 2 cannot be inserted into the holding member 1a from above due to the presence of another object above the holding member 1a. After the guide rail 2 is placed in the holding member 1a, the presser claw 6 is caulked as shown in FIG. 6 to securely hold the rail 2 in the holding member 1a. In this way, the guide rail 2 is fixed to the vehicle body 3.

As mentioned above, the guide rail 2 is inserted into the holding member, but at that time the guide rail 2 is inserted into the holding member 1.
The insertion work is very difficult because it hits the side walls 5a, 5a of a. In particular, when inserting the guide rail 2 in a direction perpendicular to the paper plane of FIG. 5, it is particularly difficult to perform the insertion operation if the guide rail 2 is long or curved. In addition, there is a possibility that the guide rail 2 may hit the holding member 1a and the guide rail 2 may be damaged. In order to eliminate such a drawback, it is possible to widen the distance between the side walls 5a, 5a of the holding member 1a, but in this case, after the rail 2 is fixed, it will shake against the holding member 1a, There is also a limit to how wide the walls 5a, 5a can be.

When crimping the presser claws 6a, 6a after inserting the guide rail 2, if the crimping force is too small, the holding force of the guide rail 2 will decrease; If the rail 2 has been subjected to surface treatment, there is a risk of it being scratched or peeled off. Furthermore, caulking requires more man-hours and is not desirable in terms of work efficiency.

Purpose The purpose of the present invention is to provide a fixation device that eliminates the above-mentioned conventional drawbacks.

Configuration In order to achieve the above object, the present invention provides a fixing device of the type described at the beginning, in which, before the holding member is fixed to the vehicle body, both side walls of the holding member are expanded from each other centering on the bottom wall side, and a bent portion is formed at a transition portion of the bottom wall to each side wall, and the bolt is connected to a mounting hole formed in a substantially central portion of the bottom wall and a corner formed in the vehicle body and aligned with the mounting hole. inserted into the hole from inside the holding member such that the head thereof is located inside the holding member;
and a square part formed between the head of the bolt and the threaded part fits into the square hole to inhibit rotation of the bolt relative to the vehicle body, and in a state before the holding member is fixed to the vehicle body, The head of the bolt is in contact with the engaging part of the bent part, and the bent part is inserted into the bolt after the guide rail is placed on the head of the bolt with the pair of both side walls opened and expanded. When the nut screwed into the threaded part of the bolt is tightened to fix the holding member to the vehicle body, the head of the bolt and the vehicle body are pressed together and bent into an overlapping state, resulting in damage to both side walls. The cross section is approximately Z-shaped so that the guide rails are rotated in the direction of closing each other and both presser claws fix and hold the guide rail. ,
We propose a configuration in which each reinforcing bead is formed.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows the appearance of an automobile in which a sunroof 10 is disposed on the roof of a vehicle body 3 so as to be movable in the direction of arrow A, and FIG. 2 shows a cross section taken along the line -- in FIG. Sunroof 10 is roof panel 1 of vehicle body 3
A fixing device 15 according to the present invention is disposed in the opening formed in the roof panel 1 and located below the roof 10, and the guide rail 2 is integrated with the vehicle body 3 by the fixing device 15. It is held fixed. Inside this rail 2, there is a sunroof 1
A guide roller (not shown) attached to the sunroof 10 is rotatably fitted thereto, and the sunroof 10 can be moved in the direction of arrow A by the rolling of the roller. In this way, the guide rail 2 serves to guide the sunroof 10.

The fixing device 15 includes an appropriate number of holding members 1 and holding members 1
It has bolts 7 and nuts 8 for fixing it to the vehicle body. The holding member 1 is made of a thin plate material, and the bolt 7
and a bottom wall 4 fixed to the vehicle body 3 by nuts 8.
, a pair of side walls 5, 5 that stand up integrally from each side end and face each other, and presser claws 6, 6 that are integrally connected to the upper end of each side wall 5, 5, and a holding member. A guide rail 2 held inside the holding member 1 is fixed to the holding member 1 by presser claws 6, 6.

Here, the difference from the conventional fixing device will be made clear by explaining the method of fixing the guide rail 2.

First, before inserting the guide rail 2 into the holding member 1, as shown in FIGS. 3 and 4, the holding member 1 is placed on the vehicle body 3, and the mounting hole formed approximately in the center of the bottom wall 4 is 30 and the bolt 7 is inserted into a square hole 31 formed in the vehicle body 3 and aligned with the mounting hole 30. At this time, the bolt 7 is inserted from inside the holding member 1, that is, from above, so that the head 16 of the bolt is located inside the holding member 1. Also bolt 7
In this case, a bolt is used in which a square part 17 is formed between the head 16 and the threaded part, and this square part 17 fits into a square hole 31 in the vehicle body 3 formed in a shape that matches the bolt. . Therefore, bolt 7 is attached to vehicle body 3.
Rotation is prohibited for. Tighten the nut 8 screwed into the threaded part of the bolt 7 to attach the holding member 1 to the vehicle body 3.
However, in the state before this fixation, the both side walls 5, 5 of the holding member 1 are expanded from each other centering on the bottom wall side as shown in FIGS. 3 and 4, and at this time, Bent parts 40, 40 having a substantially Z-shaped cross section are formed at the transition portions of the bottom wall 4 to the side walls 5, 5, and one of the bent parts abuts the lower surface of the head of the bolt 7, an engaging part 18, It consists of 18. In the state shown in FIGS. 3 and 4, the head 16 of the bolt is in contact with the engaging portions 18, 18 and is floating upward from the surface of the vehicle body 3. Further, as shown in FIGS. 2 to 4, the presser claws 6, 6 of the holding member 1 are bent in advance relative to the side walls 5, 5 in a direction in which they approach each other.

With both side walls 5, 5 opened and expanded as described above, insert the guide rail 2 into the holding member 1 from above or while sliding it in a direction perpendicular to the paper surface of FIG. 2 onto the head 16 of the bolt 7. At this time, both side walls 5, 5 are open to each other, so even if the guide rail 2 is long or somewhat curved, it can be easily inserted into the holding member 1 without damaging the rail 2. can be inserted.

Next, a nut 8 screwed into the threaded part of the bolt 7
Turn and tighten to fix the holding member 1 to the vehicle body 3. At this time, as mentioned above, bolt 7
Since the rotation of the bolt 7 is prevented, the bolt 7 sequentially moves downward as the nut 8 rotates, and the head 16 of the bolt 7 pushes down the engaging portions 18, 18 of the bottom wall 4. As a result, both bent portions 40, 40 of the bottom wall 4
is compressed by the head 16 of the bolt 7 and the vehicle body 3, and at this time, since the bent portion 30 is formed in a Z shape, the bent portion 18, 1, which bears the most load,
8; 19, 19 are bent and deformed, and both bent portions 40, 4
0 is folded into an overlapping state. Along with this, both side walls 5, 5 rotate in the direction of closing each other, and when the tightening of the nut 8 is completed, both presser claws 6, 6 press down the upper surface of the guide rail 2, as shown in FIG. , the rail 2 is fixedly held on the holding member 1.
At this time, since the holding member 1 is also fixed to the vehicle body 3 with bolts 7 and nuts 8, the rail 2 is firmly fixed to the vehicle body 3.

In order to reliably rotate the side walls 5, 5 when tightening the nut and to firmly hold the guide rail 2 after rotation, it is necessary to increase the rigidity of the side walls 5, 5 so that they do not deform themselves. Desirably, according to the configuration according to the present invention described above, when the guide rail 2 is fixedly held by the side walls 5, 5 and the presser claws 6, 6, both bent portions 40, 40 of the bottom wall 4 are folded. Since the guide rail 2 is deformed in the same state, the rigidity of the base portions of the side walls 5, 5 is increased, and the guide rail 2 can be firmly held. Moreover, both side walls 5, 5 and bottom wall 4
Reinforcement beads 20, 20; 21, 21 are formed in the area between the guide rail 2 and the respective presser claws 6, 6, respectively, and this also increases the rigidity of the side walls 5, 5, and the guide rail 2. can be held firmly. Furthermore, even when the bending portions 40, 40 are bent and deformed, the side walls 5, 5 are prevented from changing their shape or being greatly bent. In this way, the bent portions 40, 40
Since the rigidity of each side wall 5, 5 can be increased by the deformation of the holding member 1 and the reinforcing beads 20, 21, a decrease in rigidity can be prevented even if the plate thickness of the holding member 1 is made thin. Therefore, the bent portions 40, 40 can be easily deformed, and a large force is not required to tighten the nut 6. In addition, since the bolt is not configured to be screwed into a screw hole formed in the bottom wall and the side wall is rotated by tightening the bolt, the plate thickness of the holding member 1 can be reduced compared to the case where a screw hole is formed in the bottom wall. It can be made thin and the nut 6 can be turned with little force.

Effects According to the present invention, the guide rail can be easily inserted into the holding member, and the guide rail can be fixed simply by tightening the nut screwed onto the bolt, making the work simple. Moreover, there is no need to swage the presser foot. Therefore, it is possible to shorten the working time and improve the finished quality. In addition, instead of forming a screw hole in the bottom wall and tightening a bolt screwed into the hole to rotate both walls, there is no need to form a screw hole in the bottom wall, so the thickness of the holding member can be reduced. Since it can be formed thinly and the rigidity of the side wall can be increased by the deformation of the bent portion and the reinforcing bead, this also allows the holding member to be formed thinly. Therefore, it is possible to reduce the operating force when tightening the nut while deforming the bent portion. Furthermore, since the bolt does not rotate when tightening the nut, there is no need to tighten the nut while holding the guide rail by hand, which improves work efficiency.
