DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stay mounting structure for connecting between two members of a vehicle, for example, between an instrument panel and a floor panel.

[0002]

2. Description of the Related Art Conventionally, a body frame of a vehicle is assembled with side members, cross members, and the like, and a body is assembled above the body member. A stay is then mounted in place as a reinforcement or other support member. A stay is mounted vertically between the instrument panel and the floor panel as a reinforcing member. Japanese Utility Model Laid-Open No. 2-15079 discloses a reinforcing member mounted between a side member and a lateral rod.

[0003]

By the way, when a stay is attached between the instrument panel and the floor panel, if it is attached in the first half of the process, it becomes difficult to attach carpets and mats, and distortions are caused. Adjustment also becomes difficult. As shown in FIGS. 9 and 10, when the bracket 2 is welded to the instrument panel 1 and the bracket 3 is fixed with the screw 4 so that the stay 3 hangs down, the bracket 2 is used.
And the stay 3 are closely attached and fastened. When the both ends of the stay 3 are fastened in the first half of the stroke, there is the above problem. Also,
When one of the stays 3 (not shown) is removed and the screw 4 is rotated around the screw 4 for temporary tightening and fastened in the latter half of the stroke, the stay 3 is rotated to return to the original tightening position.
With the rotation of the screw 4, the screw 4 rotates, and the tightening is loosened or excessively tightened depending on the rotation direction in which the stay 3 is moved.

In addition, the work of attaching the stay 3 is a complicated operation because the two screws are tightened with the screw 4 while supporting the stay 3 and aligning the screw 4 with each other. In addition, the lower part of the stay 3 may not be visible due to poor workability due to an instrument panel projecting above the screw 3.
Is difficult to align.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a stay mounting structure having good workability when reinforcing a vehicle panel or the like in the vertical direction.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, in a stay for connecting members constituting a vehicle, a stepped screw for fastening one end of the stay is provided.
Consists of a head, a shaft, and a screw.
Cone that expands further from the head and further expands toward the head
A trapezoidal shape, and the step for inserting the stepped screw
The hole formed in-is the shaft part and screw part of the stepped screw.
Larger than the diameter of the boundary surface with one side of the peripheral edge of the hole
Form a cylindrical guide shorter than the shaft of the stepped screw
And the stepped screw is inserted into the hole from the one surface side.
The cylindrical guide slides on the peripheral surface of the shaft
Characterized in that the so that. On the other hand, in a stay for connecting members constituting a vehicle, one end of the stay is rotatably mounted on one member, and a notch groove is provided on the other end.
While extending circumferentially from the side to the center of the
The opening side is wide, the center is formed in a circular shape, and both edges of the stay
A bracket, which is the other member to which the other end of the stay is attached.
The flange is formed to have the same width as the width of the slot.

[0007]

According to the present invention, when the stepped screw is inserted into the hole from the side of the stay where the cylindrical guide is formed , the cylindrical guide and the shaft portion of the stepped screw are formed on the peripheral surface thereof. Make sliding contact . And the stepped screw on the mounting side
Of the cylindrical guide and the stepped screw
The shaft part is pressed and the stay can be firmly fixed.
You. Further, even if the stay is displaced from a predetermined position to a member on the mounting side and then returned to the original position, the stay is not loosened. In addition, one end of the stay is rotated to one member
And screw the screw slightly into the bracket beforehand.
When the other end of the stay is rotated and approached to the bracket, the entrance side of the cut groove of the stay is formed widely.
Therefore, it can be easily aligned with the screw.
Further, since the flanges formed on both sides of the stay are fitted to the peripheral edge of the bracket, the mounting position of the stay can be adjusted to the bracket.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. First, FIGS. 1, 2, 4, and 5 will be described. A stay 5 mounted between members of the vehicle is formed in a U-shaped cross section with both sides bent, and is vertically and inclined between a member bracket 7 fixed to an instrument panel member 6 and a floor panel bracket 8. And mounted. A nut 9 is welded to the member bracket 7, and a stepped screw 10 screwed to the nut 9 is composed of a head portion 11, a shaft portion 12, and a screw portion 13. It is formed in the shape of a truncated cone that further expands toward 11.

At the end of the stay 5, a hole 15 larger than the boundary surface 14 between the shaft portion 12 and the screw portion 13 of the stepped screw 10 is formed. 5 is formed at a position inside a flange 17 which will be described later, which is formed by bending the wire 5. As shown in FIG. 5, when the stepped screw 10 is fastened to the member bracket 7, the cylindrical guide 16 is formed to have a size to press against the enlarged peripheral surface of the shaft portion 12, and the length of the cylindrical guide 16 is larger than that of the shaft portion. It has been shortened.

The floor panel bracket 8 to which the other end of the stay 5 is attached projects from a floor panel (see FIG. 8) 18 and is firmly fixed by fins (see FIG. 6) 19 formed on the side surfaces. Has a nut 21 embedded therein.

As shown in FIG. 3, the other end of the stay 5 has a notch groove 22 extending in the circumferential direction from the side surface toward the center, the inlet side is wide, and the center is formed in a circular shape for tightening the screw 23. I have. A flange 17 is formed on both sides of the stay 5 so as to have a width that fits on the periphery of the inclined surface 20 of the floor panel bracket 8 to which the other end of the stay 5 is attached. It is long enough for positioning.

When attaching the stay 5, first, the end of the stay 5 is fastened to the member bracket 7 with the stepped screw 10. At this time, the other end of the stay 5 is rotated about the stepped screw 10 without being tightened and is shifted from a predetermined mounting position. Then, after completing another step, the stay 5 is rotated and pulled down to approach the inclined surface 20 of the floor panel bracket 8.
On the inclined surface 20, a screw 23 is screwed in advance from the surface of the head part with a gap of the width of the stay 5 from the surface, and cuts when the cut groove 22 of the stay 5 is fitted into the gap of the head part of the screw 23. The screw 23 hits the center of the groove 22. Next, as shown in FIG. 7, when the stay 5 is lowered along the axis of the screw 23, the flange 17 is fitted to the peripheral edge of the inclined surface 20. And screw
Tighten 23 and push carpets and mats down to assemble. The screw 23 may be a stud bolt and fastened with a nut.

As described above, the rotation of the stay 5 does not affect the tightening of the stepped screw 10. Therefore, by rotating the stay 5 toward the member bracket 7, the entire body can be conveyed without being bulky. This facilitates the assembly, does not hinder the assembly of other components, and eliminates the necessity of tightening in a line, so that the space required for tightening does not enter. Further, since the other end of the stay 5 can be fitted into the floor panel bracket 8 by using the screw 23 as a guide, the stay 5 can be easily attached even in a place where it cannot be seen. Further, the instrument panel can be forced to hang by pushing the stay 5 into the screw, and the carpet and mats can be assembled while being pushed downward, leading to an improvement in appearance.
