Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a roll bar mounting device provided in an open vehicle to protect the head of an occupant.

``Prior Art'' Automobiles designed to be able to travel off-road are equipped with roll bars to protect the heads of occupants in the event of an overturn.

FIG. 7 shows this type of automobile. Reference numeral 1 denotes a roll bar, which is hollow and has a rectangular cross section. As shown in FIG. 7, the roll bar 1 has a downward U-shape, and both ends thereof are attached to the side plates 2 of the vehicle body.

The mounting structure of the roll bar 1 to the vehicle body side plate 2 is as shown in an enlarged view in FIG.
are fixed to the inside of both ends of the roll bar 1 by welding 4, the lower part of this bracket 3 is fixed to the car body side plate 2 with bolts 5, and the stay 7, which is fixed to both the front and rear sides of the roll bar 1 by welding 6, is fixed to the car body with bolts 8. It was stuck to other parts of the side plate 2.

``Problems to be Solved by the Invention'' In the conventional mounting structure as described above, there was a problem in that the bracket 7 appeared on the outside, causing unevenness in that part and spoiling the aesthetic appearance.

Furthermore, since the bracket 3 and the stay 7 are separate parts, it is difficult to position them, the installation is troublesome, and parts management at the factory becomes complicated.

This idea solves these conventional problems,
To provide a roll bar mounting device that improves aesthetics and can be easily mounted.

``Means for Solving the Problems'' The roll bar mounting device of this invention has an upper bent portion formed by bending the four sides of a flat plate portion upward, and a rectangular opening in the center of the flat plate portion. The upper bent portion of the extension bracket includes a pair of lower bent portions formed downward facing each other on both front and rear sides of the opening, and a plate fixed to the pair of lower bent portions. the lower bent portion and the plate are inserted between the inner panel and the outer panel of the vehicle side plate, the flat plate portion is placed on the upper surface of the vehicle side plate, and the plate is attached to the inner panel. It is characterized by being fixed to the inner surface of.

``Function'' The structure is such that the flat plate part is placed on the top surface of the vehicle side plate and the plate is fixed to the inner surface of the inner panel, making positioning easy during installation and preventing the extension bracket and plate from being exposed to the outside. , the appearance is improved.

``Example'' Next, an example of this invention is shown in Figures 1 to 6.
The diagram will be explained.

FIG. 1 is a perspective view of an extension bracket 9 according to this invention, which is formed by punching and bending a single iron plate. An upper bent portion 11 bent upward, a pair of opposing lower bent portions 13 bent downward from both front and rear sides of a rectangular opening 12 provided at the center of the flat plate portion 10, and a pair of opposing lower bent portions 13. It consists of a plate 15 having a U-shaped planar shape fixed by welding 14 between bent portions 13, and a hole 16 for bolt insertion is bored in the plate 15.

FIG. 2 is an enlarged sectional view of an embodiment of this invention applied to the part indicated by the arrow in FIG. 7, and FIG. 3 is a sectional view taken along the line - in FIG. 1 is an inner panel 20 and an outer panel 21
are fixed by welding 22 at both ends to form a hollow interior, and the lower end, that is, the inner surface of the hollow part of the end of the roll bar 1, which is the attachment part to the vehicle body side plate 2, is shown in FIG. The upper bent portion 11 of the extension bracket 9 is inserted, and the upper bent portion 11 is fixed to the inner surface of the hollow portion at the end of the roll bar 1 by welding 17 (see FIG. 3).

As shown in FIGS. 4 and 5, the vehicle body side plate 2 has an inner panel 23 and an outer panel 24 welded together.
It is fixed and formed into a hollow shape. The lower bent portion 13 of the extension bracket 9 and the plate 15 fixed thereto by welding 14 are inserted into the interior of the vehicle body side plate 2 through a hole 18 provided on the upper surface of the vehicle body side plate 2, and the flat plate Part 10 (see Figure 3)
is placed on the upper surface of the vehicle body side plate 2 via a sealing rubber 19 (see FIG. 2).

A recess 26 is formed in the inner panel 23 of the vehicle side plate 2, and a bolt 27 inserted into the recess 26 and a nut 28 screwed into the recess 26 allow the lower plate 15 of the extension bracket 9 to be fixed.
is fixed to the inside of the side plate 2. In this case, the nut 28 is preferably welded to the hole 16 of the plate 15.

In the embodiment described above, the recess 2 of the vehicle side plate 2
Extension bracket 9 plate 1 inside 6
5 is in direct contact with the inner panel 23, however, as shown in FIG. 6, another member, the gusset 29, may be interposed by being fixed to the inner panel 23 by welding 30. In this way, the rigidity of this portion can be increased.

"Effect of the invention" As explained above, this invention has an upper bent part 11 of the extension bracket 9 on the inner surface of the hollow part of the end of the roll bar 1, which is the attachment part to the side plate 2 of the vehicle body.
and a plate 1 fixed to the lower bent portion 13 of the extension bracket 9 and the lower bent portion 13.
5 is inserted between the inner panel 23 and outer panel 24 of the vehicle side plate 2, and the plate 15 is fixed to the inside of the inner panel 23. Therefore, when attaching the roll bar 1 to the vehicle side plate 2, To,
Upper bent portion 11 of extension bracket 9
After fixing to the inner surface of the hollow part of the roll bar 1 end,
By placing the flat plate part 10 on the upper surface of the vehicle body side plate 2, the flat plate part 10 acts as a stopper, and the work of fixing the plate 15 and the inner panel 23 can be performed extremely easily and smoothly. There is.

In addition, the roll bar 1 can be attached to the vehicle body side plate 2 by only using the extension bracket 9 and the plate 15 fixed to it, without using the stay 7 as in the conventional case, so the mounting structure is different from the conventional one. Since the parts are not visible from the outside, the appearance can be improved, and the number of parts is reduced to one, which has the effect of simplifying parts management in the factory.
