[0002]

2. Description of the Related Art An industrial vehicle of this type, for example, a forklift, has a body 5 of a forklift 51 as shown in FIG.
A load is placed on a fork 52 provided on the front side of 1a and transported to a predetermined place. A counter weight 53 is provided on the rear side of the vehicle body 51a. When a load is placed on the fork 52, the center of gravity of the forklift 51 moves forward, and the rear side of the forklift 51 rises. For this reason, a counterweight 53 serving as a weight is provided on the rear side of the forklift 51. Thereby, the cargo handling stability of the forklift 51 and the running stability of the forklift 51 are maintained.

An engine hood 54 is provided in front of the counterweight 53 so as to cover an engine (not shown), and a seat 55 is fixed on the engine hood 54. The engine hood 54 is rotatably connected to the counterweight 53 via a hinge member 56. When checking the engine, the engine hood 5
4 is released.

[0004]

In order to maintain the stability and the like of the forklift 51, it is necessary to make the counterweight 53 heavy, and the counterweight 53 becomes large. In the conventional forklift, since the upper surface of the engine hood 54 and the upper surface of the counterweight 53 are formed at substantially the same height, the rear portion of the vehicle body 51a is relatively long, and the turning radius of the forklift is large. There is a demand that the turning radius be reduced in order to enhance the workability of the forklift, and in order to satisfy this demand, it is necessary to shorten the body length of the forklift 51. Then, while securing the weight of the counterweight 53, the forklift 5

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) A first embodiment in which the present invention is embodied in a forklift will be described below with reference to FIGS.

As shown in FIG. 1, a fork 2 is provided in front of a vehicle body 1a of a forklift 1 as an industrial vehicle. On the other hand, in order to secure the stability of the forklift in loading and transporting the fork 2,
On the rear side of a, a counter weight 3 serving as a weight is provided. The rear side of the counterweight 3 is formed in an arc shape. The counter weight 3 is formed vertically long in order to shorten the length in the front-rear direction, and the upper end of the counter weight 3 is formed higher than the upper end of the engine hood 4. A notch 3b is provided on the front side of the counterweight 3. The counter weight 3 is formed by filling a hollow body formed of an iron plate into a predetermined outer diameter shape with lead.

The counterweight 3 has a recess 3a on the upper surface near the engine hood 4. FIG. 2 (a)
As shown in the figure, the concave portion 3a is formed by a substantially semi-cylindrical hollow which is also opened to the engine hood 4 side.
Further, the bottom surface of the concave portion 3a is formed horizontally. The position where the recess 3a is provided is a position corresponding to the seat when the engine hood is fully opened, that is, when the opening angle of the engine hood where the upper surface of the engine hood 4 is vertical is 90 degrees, the rear end 5a of the upper end of the seat 5 is located It is provided so as to be in a position to contact the bottom surface.

An engine hood 4 is provided in front of the counterweight 3 so as to cover an engine (not shown), and a seat 5 is fixed on the engine hood 4.

Behind the engine hood 4, two columns 7 for supporting the head guard 6 are provided. FIG.
As shown in (a), the column 7 is disposed at a position corresponding to the notch 3b provided in the counterweight 3.

As shown in FIGS. 2 (a) and 2 (b),
, A first bracket 8 is attached. The first bracket 8 is formed of a square plate. Further, it is fixed to the column 7 by welding. On the other hand, a second bracket 9 is attached to the engine hood 4. The second bracket 9 is formed in an L shape, and is fixed to the upper rear portion of the engine hood 4 by welding. The second bracket 9 is rotatably supported on the first bracket 8 via a rotation shaft 10. The engine hood 4 can be opened up to an opening angle of 90 degrees (a state in which the upper surface of the engine hood 4 is vertical).

Next, the operation of the forklift 1 configured as described above will be described. When performing operations such as maintenance and inspection of the engine, the operator opens the engine hood 4. As shown by a two-dot chain line in FIG. 1, when the engine hood 4 is opened, the engine hood 4 and the seat 5 are rotated rearward about the rotation shaft 10. Then, the seat 5 is rotated until the upper end rear portion 5a of the seat 5 comes into contact with the bottom surface of the recess 3a of the counterweight 3, and a part of the seat 5 is accommodated in the recess 3a. At this time, the opening angle of the engine hood 4 is substantially 90 degrees.

Since the concave portion 3a is provided on the upper surface of the counterweight 3, the rear end 5a of the upper end of the seat 5 has the concave portion 3a.
The engine hood 4 is opened until it contacts the bottom surface of the engine hood.
For this reason, even in the forklift 1 in which the upper end of the counter weight 3 is provided at a position higher than the upper end of the engine hood 4, the opening angle of the engine hood 4 is increased, and work such as maintenance and inspection of the engine is facilitated.

Further, since the opening angle of the engine hood 4 becomes substantially 90 degrees, the center of gravity of the engine hood 4 and the seat 5 moves to the counterweight 3 side. Therefore, the engine hood 4 and the seat 5 are locked in the concave portions 3a, and there is no need to lock the engine hood 4 with a stay or the like.

On the other hand, the counterweight 3 has a shorter length in the front-rear direction, but is formed vertically longer than the upper end of the engine hood 4. Therefore, there is no problem in the role of the counterweight 3 as a weight. Therefore, the forklift 1 is also stable during the loading and unloading work of the forklift 1. In addition, the overall length of the vehicle body 1a is reduced by an amount corresponding to the reduction in the length of the counter weight 3 in the front-rear direction,
The turning radius of the forklift 1 is reduced.

According to the above embodiment, the following effects are obtained. (A) Since the concave portion 3a is provided in the counter weight 3, when the engine hood 4 is opened, a part of the seat 5 is accommodated in the concave portion 3a, and the engine hood 4 is fully opened compared to the case where the concave portion 3a is not provided. Opening angle becomes larger.

(B) Since the opening angle of the engine hood 4 is substantially 90 degrees, the engine hood 4 and the seat 5 are locked in the concave portions 3a, and there is no need to lock the engine hood 4 with a stay or the like. .

(C) When the counter weight 3 is vertically elongated,
Since the upper end of the counter weight 3 is formed higher than the upper end of the engine hood 4, even if the length of the counter weight 3 in the front-rear direction is reduced, there is no problem in the role of the counter weight 3 as a weight. Therefore, the forklift 1 is also stable during the loading and unloading work of the forklift 1. In addition, by reducing the length of the counterweight 3 in the front-rear direction, the overall length of the vehicle body 1a is reduced, and the turning radius of the forklift 1 can be reduced. As a result, workability of the forklift 1 is improved. (Second Embodiment) Next, a second embodiment will be described with reference to FIG.
A description will be given according to (a) and (b). In this embodiment, the same members as those in the first embodiment are denoted by the same reference numerals, and detailed description is omitted. Therefore, the following description focuses on differences from the first embodiment.

As shown in FIGS. 3 (a) and 3 (b), this embodiment differs from the first embodiment in that the shape of the recess 3a is different. The recess 3a is provided with the engine hood 4
Is formed so that the accommodation space 11 exists below the seat 5 in a state where a part of the seat 5 is accommodated in the concave portion 3a when the seat is fully opened. That is, as shown in FIG. 3A, a substantially semi-cylindrical concave portion is further provided at the bottom of the concave portion 3a on the engine hood 4 side. Therefore, the recess 3
The bottom of a has a step. A protrusion 12 is formed on the bottom surface of the recess 3a on the engine hood 4 side as a restricting portion extending in the left-right direction on the engine hood 4 side. The ridge 12 is formed with a communication portion 15 that connects the inside 13 and the outside 14 of the concave portion 3a. In addition, the concave portion 3
The position at which a is provided is the same as in the first embodiment.

In this embodiment, a recess is further provided at the bottom of the recess 3a on the engine hood 4 side, so that the accommodation space 11 exists below the seat 5 even when the engine hood 4 is fully opened. Therefore, even when the engine hood 4 is fully opened, small items can be placed in the housing space 11.

Further, since the protrusion 12 is provided on the engine hood 4 side, when the concave portion 3a is used as a small container, small items placed in the concave portion 3a are hard to come out of the concave portion 3a and hardly fall from the forklift 1. Become.

Further, since the communication portion 15 is provided on the ridge 12, even if rainwater enters the recess 3a, the rainwater flows out of the recess 3a through the communication portion 15. According to this embodiment, the following effects are obtained in addition to the effects of the first embodiment.

(A) Even when the engine hood 4 is fully opened, the housing space 11 is present in the recess 3a.
a can be used as a accessory case. (B) Since the ridge 12 is provided on the engine hood 4 side, when the recess 3a is used as a small container when the engine hood 4 is closed, the small ridge 1 prevents the small item from coming out of the recess 3a.
2 makes it difficult to drop from the forklift 1.

(C) Since the communicating portion 15 is provided on the ridge 12, even if rainwater enters the concave portion 3a, it flows down through the communicating portion 15 and does not accumulate in the concave portion 3a. The embodiment is not limited to the above, and may be, for example, the following case. The opening angle when the engine hood 4 is fully opened is not limited to 90 degrees, and may be any opening angle that does not interfere with maintenance and inspection work, and may be smaller than 90 degrees. In this case, a stay for maintaining the open state is required. Therefore, the opening angle is 9
It is preferable that the angle is 0 degrees or more. If the angle is larger than 90 degrees, the width of the engine hood 4 needs to be smaller than the width of the column 7. The bottom surface of the concave portion 3a may be formed so as to be inclined downward toward the engine hood 4, for example, as shown in FIG. In this case, even if rainwater enters the concave portion 3a, it flows down due to the inclination, and the rainwater does not accumulate in the concave portion 3a. The buffer member 16 may be attached to the bottom of the recess 3a as shown in FIG. As the cushioning member 16,
For example, there are rubber and sponge. In this case, even if the seat 5 hits the recess 3a, the seat 5 is less likely to be damaged. The shape of the concave portion 3a may be any shape as long as a part of the seat 5 can be accommodated. For example, the concave portion 3a has a hole formed by cutting out only the position of the upper surface of the counter weight 3 where the seat 5 contacts. Is also good. Further, a groove extending in the front-rear direction or the left-right direction may be formed on the upper surface of the counterweight 3. The shape of the seat 5 is not limited to the shape in which the back of the backrest is inclined rearward, and may be, for example, a shape in which the back of the backrest is formed perpendicular to the upper surface of the engine hood 4. In this case, when the engine hood 4 is fully opened, not only the upper end 5a of the seat 5 but also the upper surface of the back of the backrest of the seat 5 may contact the bottom of the recess 3a. In the second embodiment, a hole may be formed instead of the communication portion 15. The hole may be provided on the side instead of being provided in front of the concave portion 3a. Even in this case, the rainwater flows down through the hole, and the rainwater does not accumulate in the recess 3a. The configuration of the counterweight 3 is not limited to the one described above, and may be entirely formed of lead or casting. The engine hood 4 may be rotatably connected to the counterweight 3 via a hinge. The protrusions 12 may be any as long as they can lock small items placed in the recesses 3a and can prevent the load from dropping. For example, the protrusions 12 may be dotted. ○ The mounting position of the first bracket 8 is the engine hood 4
As long as it is rearward, for example, it may be mounted so that the position of the rotating shaft 10 is higher. In this case, as the position of the rotating shaft 10 rises, the seat 5 hardly comes into contact with the concave portion 3a of the counterweight 3 and the engine hood 4
Opening angle becomes larger.

In the following, technical ideas other than the claims that can be grasped from the above embodiment will be described together with effects. (1) An industrial vehicle according to any one of claims 1 to 5, wherein the width of the engine hood is smaller than the width between the columns. In this case, the opening angle of the engine hood can be set to 90 degrees or more. In addition, since the center of gravity of the opened engine hood and the seat moves to the counterweight side, there is no need to lock the engine hood with a stay or the like in the fully opened state.

(2) The industrial vehicle according to any one of claims 1 to 5, wherein the industrial vehicle is a forklift. In this case, it is possible to provide a forklift capable of reducing the turning radius and sufficiently securing the opening angle of the engine hood.

[0036]

As described above in detail, according to the first to fifth aspects of the present invention, since the recess is provided in the counterweight, when the engine hood is fully opened, a part of the seat is in the recess. The opening angle of the engine hood is larger than in the case where it is accommodated and there is no concave portion. Further, since the counterweight is vertically elongated and the upper end of the counterweight is formed higher than the upper end of the engine hood, the length of the counterweight can be reduced while securing the weight of the counterweight. Therefore, the body length of the forklift is reduced, and the turning radius of the forklift can be reduced.

According to the second aspect of the present invention, it is difficult for rainwater to collect in the recess. According to the invention described in claim 3,
Even if rainwater enters the recess, the rainwater flows down due to the inclination, and the rainwater does not accumulate in the recess 3.

According to the fourth aspect of the present invention, even when the engine hood is fully opened, the accommodating space exists in the recess, so that the recess can be used as a small container. In addition, since the restricting portion is provided on the engine hood side, when the concave portion is used as a small container when the engine hood is closed, the small portion can be prevented from coming out of the concave portion by the restricting portion, so that the small portion does not easily fall from the forklift. Further, since the communication portion is provided in the regulating portion, even if rainwater enters the recess, the rainwater flows down through the communication portion, and the rainwater hardly collects in the recess.

According to the fifth aspect of the present invention, even if the seat hits the recess, the seat is less likely to be damaged.
