[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal device for a forklift truck capable of reliably preventing rainwater or the like from entering.

[0002]

2. Description of the Related Art Conventionally, a forklift truck is provided with a counterweight at a rear portion of a vehicle body in order to stabilize a cargo operation. In front of the counterweight is a power room that houses the engine, etc.
As shown in FIG. 5, the hood a is openable and closable, and a seal member c is provided at the rear of the hood a to prevent rainwater and dust from entering through a gap between the hood a and the counterweight b. The seal member c is fitted to the tip of a reinforcing rib d protruding inside the hood a. When the hood a is closed, the lower end of the seal member c is brought into contact with the upper surface of the counterweight b from above. It has become. In the drawing, e indicates a vent hole opened in the reinforcing rib d. Further, as an example in which the sealing member c is fitted to the tip of the reinforcing rib d,
Some are shown in FIG. 5 and FIG.

[0003]

However, in the case where the sealing member c is fitted to the reinforcing rib d as in the conventional sealing device, the ventilation hole e opened in the reinforcing rib d has the invasion direction of rainwater, dust and the like. The drawback is that rainwater and dust easily enter the power room. Further, when electric components such as a motor are provided in the power room, there are disadvantages such that these electric components are deteriorated early due to rainwater, dust, or the like, or break down. This invention has been made for the purpose of eliminating the above-mentioned conventional disadvantages, and it is an object of the invention to provide a seal device for a forklift truck which can surely prevent intrusion of rainwater or the like.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a forklift truck having a power room partially covered by a hood which can be freely opened and closed, and a counterweight provided behind the power room. A sealing member for preventing a rainwater or dust from entering the power chamber by forming a fold-back portion for reinforcement at a peripheral portion of the hood which can be opened and closed, and making contact with an upper surface of the counterweight at the fold portion; And a vent hole is opened vertically in the folded portion.

[0005]

According to the above configuration, since the directions of entry of rainwater and dust do not coincide with the ventilation holes, it is possible to reliably prevent rainwater and dust from entering the power room.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with reference to the drawings shown in FIGS. FIG. 1 is a side view of a forklift truck, FIG. 2 is a plan view near a power room, and FIG. 3 is an enlarged cross-sectional view taken along line AA of FIG. In these figures, reference numeral 1 denotes a vehicle body, and a mast 2 is provided upright at a front portion. A fork 4 is mounted on a finger board 3 which is mounted on the mast 2 so as to be vertically movable. A power room 5 containing an engine (not shown) is provided at the rear of the vehicle body 1.
The periphery of the power room 5 is covered with a hood 8, a driver's seat 6 is provided on the hood 8, and a counterweight 7 is provided behind the power room 5.

The rear portion of the hood 8 is openable and closable by a hinge 9, and a reinforcing fold 8a is formed at the rear edge of the openable hood 8 by folding a part of the hood 6. . The folded portion 8a is shown in FIG.
As shown in FIG. 7, a plurality of circular or rectangular vents 8b which are curved in an arc shape along the arc of the counterweight 7 and open vertically in a horizontal portion are formed. Also, a sealing member 10 is provided at the leading edge of the folded portion 8a.
Is fitted. The seal member 10 is integrally formed of an elastic body such as rubber, and the folded portion 8 is formed on a side surface.
A concave groove 10a is formed so as to be fitted to the leading edge of the groove a.

On the lower surface, a cylindrical seal portion 10b is formed along the longitudinal direction. When the hood 8 is closed, the seal portion 10b is formed on the upper surface of a step 7a formed at the front of the counterweight 7. To prevent rainwater, dust, and the like from entering the power chamber 5. In the figure, reference numeral 12 denotes electrical components such as a motor installed in front of the counterweight 7 in the power room 5.

The operation of the forklift truck will now be described. When the forklift truck is operated, the hood 8 covering the rear portion of the power chamber 5 is closed, and the seal member 10 fitted to the fold-back portion 8a for reinforcement uses the hood 8 due to its own weight. Counter weight 7
3 is pressed against the upper surface of the stepped portion 7a as shown in FIG. Therefore, when working in the rain or in a place where there is a lot of dust, even if rainwater, dust or the like enters through the gap 13 between the rear end of the hood 8 and the counterweight 7 as shown in FIG. In order to prevent this, it is possible to prevent intrusion into the power chamber 5. In addition, since the ventilation hole 8b formed in the folded portion 8a is opened in the vertical direction,
This does not coincide with the direction of entry of rainwater or dust, whereby it is possible to prevent rainwater or dust from entering the power chamber 5 through the ventilation hole 8b.

[0010]

[Effects of the Invention] As described in detail above, this invention forms a fold-back portion for reinforcement on the periphery of the hood which can be opened and closed,
A seal member for preventing rainwater and dust from entering the power chamber is provided in the folded portion, and a ventilation hole is opened in the folded portion in a vertical direction. Since it is attached, there is no need to provide a reinforcing rib on the hood, and the structure of the hood can be simplified, so that the hood can be provided at low cost. In addition, since the ventilation holes that connect the power room and the outside air are opened in the vertical direction, it is difficult for rainwater and dust to enter the power room, and the electrical components installed in the power room are quickly deteriorated by rainwater and dust. It can also eliminate disadvantages such as breakage and breakdown.
