Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a roof reinforcement.

[0002]

2. Description of the Related Art Roof reinforcements have both ends attached to left and right roof side panels to reinforce a vehicle body roof. FIG. 4 shows a mounting structure of the roof reinforcement in a vehicle having a high ceiling such as a wagon vehicle. In the roof reinforcement 1, the middle portion is gradually curved, and both ends are curved with a large curvature. The right and left roof side panels 2 are superposed at right angles from above and fastened by screws 3. In this structure for mounting the roof reinforcement, the roof reinforcement 1
Has a hat-shaped cross section, a concave portion 4 protruding outward at the center of the end, and a screw insertion hole 5 is formed in the concave portion 4. The screw 3 is inserted into the screw insertion hole 5, and the screw 3 is screwed into the roof side panel 2 to fasten the roof reinforcement 1 to the roof side panel 2.

[0003]

However, in the above-described structure for mounting the roof reinforcement, the end of the roof reinforcement 1 is fastened by one screw 3, so that the roof reinforcement 1 is attached to the roof side panel. 2 may be fixed (tilted) out of a predetermined direction (perpendicular direction). In such a case, as shown in FIG. 5, one side of the roof reinforcement 1 is lifted up at the center of the roof panel 6 in the width direction, and there is a case where bonding cannot be performed. Further, there is a possibility that the adhesive 7 may be peeled off even if the bonding is forcibly performed, and in that case, there is a possibility that deformation (deformation) may occur in the roof panel portion A of one of the remaining bonded portions. There is. In order to prevent such a situation, as shown in FIG. 6, as shown in FIG. 6, the roofing reinforcement 1 is fastened to the roof side panel 2 at two places by using two screws 3, thereby securing the roofing reinforcement 1. The roof side panel 2 is installed in a correct posture, but in this case, the installation of the roof reinforcement 1 requires time and effort. Moreover, in the normal screw fixing structure, the screw insertion hole 5 of the roof reinforcement 1 is formed larger than the diameter of the screw 3 to absorb the mounting error. As a result, it is difficult to accurately set the roof reinforcement 1 with accuracy.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object thereof is to easily attach a roof reinforcement to a roof side panel in a proper posture and to increase strength. It is another object of the present invention to provide a structure for mounting a roof reinforcement for further improving the appearance.

[0005]

In the structure for mounting a roof reinforcement according to the present invention, a bead is formed at an end of the roof reinforcement along the longitudinal direction of the roof reinforcement, and a roof side panel is formed. On the mounting surface of the roof reinforcement,
Forming a bead facing the bead of the roof-free reinforcement, fitting the bead, positioning the roof-free reinforcement on the roof side panel, and fixing the roof-free reinforcement to the roof side panel. It is characterized by:

According to the structure for mounting a roof-free reinforcement of the present invention, the bead of the roof-free reinforcement can be fitted to the bead of the roof side panel to position the roof-free reinforcement. Therefore, the roof reinforcement is fixed to the roof side panel with a single screw in a predetermined position, the adhesion between the roof reinforcement and the roof panel is assured, the mounting work is easy, and the bead is used to secure the body. Strength also increases.

In the structure for mounting a roof reinforcement according to the present invention, in claim 1, the two beads are formed, and the roof reinforcement and the roof side panel are screwed between them. .

[0008] According to the roof-reinforcement mounting structure of the present invention, the head of the screw is located between the beads,
Since the head of the screw does not protrude from the roof reinforcement, the appearance is improved.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example in which the structure for mounting a roof reinforcement according to the present invention is applied to a one-box car. This vehicle 10 has a slide door 10a in the middle of both sides of the vehicle body. The roof 10b located at the front end and the rear end of the sliding door 10a
Has roof side panels 11 arranged on both sides of the vehicle.
Roof Reinforcement 12
Is arranged.

[0010] Those roof reinforcements 12
The middle part is slightly upwardly curved in accordance with the shape of the roof 10b, and both ends are downwardly curved with a large curvature as shown in FIG. Further, the roof reinforcement 12 has two beads 13 extending at both ends thereof in the longitudinal direction of the roof reinforcement 12 and protruding inward. The beads 13, 13 are joined together toward the middle part of the roof reinforcement 12, and become one large bead at the middle part to define a cross section of the roof reinforcement 12 in a hat shape. . The roof reinforcement 12 has elongated holes 1 formed in flat portions 14 defined between the beads 13 at both ends.
5 are formed.

On the other hand, a step 16 which is opened upward is formed in a mounting portion of the roof side panel 11 to which the roof reinforcement 12 is attached, and a bead 13 of the roof reinforcement 12 is formed in the step 16. , 13 are formed. further,
An emboss 19 is formed in a flat portion 18 defined between the beads 17.

In the structure for mounting the roof reinforcement as described above, first, the beads 13 of the roof reinforcement 12 are fitted to the beads 17 of the roof side panel 11 to position the roof reinforcement 12. Aim. Next, the tapping screw 20 is screwed into the emboss 19 of the roof side panel 11 through the long hole 15 of the roof reinforcement 12. Then, the tapping screw 20 becomes the emboss 19
The roof thread panel 12 is fastened to the roof side panel 11 by cutting the female screw into the roof side panel 11.

In the above embodiment, the tapping screw 20 is used.
Is screwed into the emboss 19 of the roof side panel 11, but a common screw (bolt) may be used instead of the tapping screw 20, and the tip of the screw may be fastened by a nut. In this case, the roof side panel 1
1, a screw insertion hole is formed instead of the emboss 19, and the roof side panel 11 is formed so as to match the screw insertion hole.
Nuts may be welded to the back side of. Further, in the above embodiment, the two beads 13 and 17 are formed on the roof reinforcement 12 and the roof side panel 11, but the number of the beads may be one or three or more. . Furthermore, in the above embodiment, an example is shown in which the present invention is applied to a one-box car, but the present invention is not limited to a one-box car.

[0014]

As described above, the mounting structure of the roof reinforcement according to the present invention has the following effects. The bead of the roof reinforcement is fitted to the bead of the roof side panel to position the roof reinforcement, and the screw is then used to fasten the roof reinforcement to the roof side panel. Therefore, the Rufley Reinforcement is
With one screw, it can be attached to the roof side panel accurately and in the correct posture, the glue between the roof reinforcement and the roof panel is ensured, the installation work is easy, and the bead increases the body strength.

Further, according to the present invention, since two beads are formed and the head of the screw is located between them, the head is accommodated in the roof free reinforcement, so that the appearance is improved.
