DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hood for an industrial vehicle which is a cover for a battery or an engine of an industrial vehicle represented by, for example, a forklift.

[0002]

2. Description of the Related Art Heretofore, as this kind of hood for industrial vehicles, for example, a square horn having a square shape has been used. However, the left and right corners on the front end side of the hood are rounded so as not to be an obstacle when an operator (operator) gets on and off, so that smooth getting on and off is possible.

Here, a conventional hood for an industrial vehicle used for a forklift will be described with reference to FIGS. 9 and 10. FIG. That is, in FIG. 9, reference numeral 30 denotes a forklift, and a hood 32 provided with a seat 31 of the forklift 30 on an upper surface thereof is provided so as to cover a plurality of batteries (not shown).

As shown in FIG. 10, the bonnet 32 has a pair of left and right C chamfers 33a at the front end thereof.
The hood body 33 includes a plurality of screw portions 33c for attaching the seat 31 to the flat portion 33b, and a pair of left and right corner members 34 attached to the pair of left and right C chamfers 33a by welding. The corner member 34 is made of sheet metal, is formed by a die press, and is flatly contacted and welded to the C chamfered portion 33a without any gap, and a corner R formed on the back surface of the flat portion 34a. Perpendicular to the flat portion 34a and the corner R portion 34b, the bonnet body 3
The horizontal portion 34 connected substantially in parallel to the two flat portions 33b
c.

[0005] Even if the corner R portion 34b hits a leg of an operator (operator), the corner R portion 34b can smoothly get on and off. After the welding operation of the bonnet main body 33 and the corner member 34, the raised portion of the weld bead on the surface is ground and removed by a grinder.

[0006]

However, according to the bonnet 32 described above, the corner member 34 must be separately formed and welded to the bonnet main body 33. After the welding, the raised portion of the weld bead is ground and removed. Since it must be done, the number of finishing steps increases. This is disadvantageous because it increases the manufacturing cost. Further, the grinding and removing operation is performed manually, and if the grinding and removing are performed excessively, the bonnet body 33 or the corner member 34 will be damaged. As a result, there is a problem that the appearance quality is deteriorated, and the number of finishing steps is further increased.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a bonnet for an industrial vehicle which has a rounded front end to improve ease of getting on and off and has a small number of finishing steps.

[0008]

According to a first aspect of the present invention, there is provided a bonnet for an industrial vehicle having a seat provided on an upper surface side. The shape of the bonnet body is made of metal, and a pair of left and right notches are formed at the front end side of the bonnet, and non-metal corner members are attached to these notches.

Therefore, according to the first aspect of the present invention, since the non-metallic corner member can be easily attached to the cutout portion of the bonnet body using a bolt or the like, the welding operation and the grinding and removing operation after the welding operation are performed. Becomes unnecessary.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below.
A state adopted in a forklift (an example of an industrial vehicle) will be described with reference to FIGS.

FIG. 1 shows a hood 1 for an industrial vehicle such as a forklift, in which a seat 31 can be mounted on the upper surface side. This bonnet 1 is a bonnet body 2
And the corner member 3.

As shown in FIG. 3, the bonnet main body 2 is formed in a convex shape by forming a pair of left and right notches 2a and 2b at the front end of a square metal plate.
As shown in FIG. 5, the left and right projections behind the notches 2a and 2b are upper U-shaped sections 2 having an inverted U-shaped cross section.
c and 2d are separately press-molded to increase the thickness when viewed from the side. As shown in FIG. 6, in the next step, the edge 2 e of the convex portion is press-formed into a curved end 2 f that gradually tilts downward, and the front portion of the bonnet body 2 is further rounded. Shape. A plurality of screw portions 4 for mounting the seat are provided from substantially the center of the square to the front.

As shown in FIG. 1, the resin-made corner member (an example of a non-metallic corner member) 3
A and 2b are formed in an inverted U-shape in cross section in the same manner as the upper protruding portions 2c and 2d. The shape of the inverted U is gradually reduced toward the front end. Further, at the rear end portion of the corner member 3, an insertion portion 3a which can be fitted inward from the front with respect to the front end portions of the upper protruding portions 2c and 2d is continuously provided rearward. An engaging portion 3b which can be fitted from the side to the lower side of the side end portion such as the end portion 2f is continuously provided inward, and these insertion portions 3a and the engaging portion 3b are
It is integrally formed at the time of resin molding of the corner member 3 made of resin.

The operation of the above embodiment will be described below. Insertion portion 3 of corner member 3 made of resin
a can be fitted inside the front end portions of the upper protruding portions 2c and 2d by bolts (not shown) or the like, and the locking portions 3b can be fitted below the side end portions such as the curved end portions 2f. And can be attached by bolts (not shown) or the like. This eliminates the need for a welding operation and a grinding removal operation after the welding operation.

The seat 31 can be attached to the threaded portion 4 of the bonnet body 2 using bolts (not shown) or the like. Thus, the hood 1 can be assembled as shown in FIG.

The cross section of the corner member 3 made of resin has an inverted U shape.
Since the edge 2e of the convex portion is formed as a curved end 2f which gradually tilts downward, the leg of the operator (operator) is formed of a resin corner member. Even if it hits No. 3, it can be easily slid, and the getting on and off property improves.

Further, the left and right upper protruding portions 2c and 2d and the curved end portion 2f of the bonnet main body 2 are press-formed in separate steps, respectively, so that each of them is integrally formed by press-forming in the same step. In comparison with the case, even a different model in which the width of the bonnet main body 2 changes can be formed without changing the die press. When the longitudinal direction of the bonnet body 2 changes, the press forming performed in the above-described separate steps or the press forming performed in the same step can be performed without changing the die press.

Therefore, by forming the bonnet in separate press steps, it is possible to cope with another type of industrial vehicle whose length in the width direction is changed by the same die press.
As a result, production equipment investment costs can be reduced.

Next, another embodiment of the present invention will be described with reference to FIG. This hood 1A for industrial vehicles is:
It is used in forklifts with engines, etc.
The upper protruding portions 2c, 2d, and 2g are integrally formed in right and left and rear U-shape, and the edge portion 2e of the convex portion is formed in a curved end portion 2f that gradually tilts downward. The left and right edges 2e, 2h, 2i, 2j are formed deep downward, and the resin corner member (an example of a non-metal corner member) 3A is formed along the notches 2a, 2b.
The joining margins 3c and 3d are joined together without any gap using bolts (not shown) or the like, and are formed so as to be integrally curved with the upper protruding portions 2c and 2d and the curved end portion 2f. ing. And the left or right notch 2a,
2b. Other than this configuration, the configuration is the same as that of FIG.

With such a configuration, the joining margin 3c of the resin corner member 3A can be fitted under the front end portions of the upper protruding portions 2c and 2d and attached by bolts (not shown) or the like. Then, the joining margin 3d is fitted under the side end portion of the curved end portion 2f, and a bolt (not shown) is inserted.
It can be attached by such as. Thus, as in FIG. 1, the welding operation and the grinding and removing operation after the welding operation are not required.

The seat 31 can be attached to the screw portion 4 of the bonnet body 2A using bolts (not shown) or the like, whereby the bonnet 1A can be assembled.
Further, even when the leg of the operator (operator) hits the corner member 3A made of resin, the leg can be easily slipped, so that the getting on and off property is improved.

Next, still another embodiment of the present invention will be described.
A description will be given based on FIG. Here, compared to FIG. 1, an opening 5 is provided on the inner side surface of the corner member 3B made of resin so that four fingers can enter. Other than this configuration, the configuration is the same as that of FIG.
