Description

[0001]
BACKGROUND OF THE INVENTION
The present invention belongs to an engine hood of an industrial vehicle, and particularly relates to an improvement of a lock mechanism of the engine hood.
[0002]
[Prior art]
For example, in the case of a forklift that is one of industrial vehicles, the lower part of the driver's seat is an engine hood 4 as shown in FIG. 3, and when adjusting the engine, the engine hood can be opened from the front side. ing.
Such an engine hood of an industrial vehicle has a lock mechanism including a hook 12 provided on the vehicle body 9 side and a locking body 3 provided on the engine hood 4 side as shown in FIG. The hook 12 is locked by locking. The operation for opening the engine hood 4 is performed by operating the cable 5 provided at the lower end of the hook 12 to rotate the hook 12 about the rotation shaft 12a to release the engagement with the locking body 3. The hood is lifted by hand.
[0003]
[Problems to be solved by the invention]
The engine hood of the above industrial vehicle is usually sealed with a band-shaped rubber body 11 or the like in the open portion or the like, and the surface is often smooth and round in appearance. The opening operation is troublesome because there is no part that can be hooked, and even when the lock is released, the engine hood 14 has its own weight.
Therefore, an object of the present invention is to provide an engine hood for an industrial vehicle that can be easily opened and opened without changing the appearance, even if the engine hood has a smooth appearance and has no part to be touched. is there.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, an engine hood for an industrial vehicle according to the invention of claim 1 is locked by a lock mechanism provided between the engine hood and the vehicle body, and is incorporated into the lock mechanism when the lock is released. In an engine hood of an industrial vehicle that pushes up an engine hood by a push-up mechanism , the lock mechanism includes a locking body provided on the engine hood, a hook that pivotally locks on the locking body by pivoting on the vehicle body, and a hook. And the push-up mechanism is integrated with the hook so as to press the locking body from below when the hook rotates and releases the engagement with the locking body. The hook is rotated by the operation of the cable and the lock is released, and the engine hood continues to the push-up member. Characterized in that it is pushed up Ri.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described with reference to the drawings. FIG. 1 shows a lock mechanism 10 which is a main part of an engine hood of an industrial vehicle of the present invention, and FIG. 2 shows an operation mechanism when the lock mechanism 10 is applied to a forklift.
[0007]
As shown in the drawing, the lock mechanism 10 is composed of a hook 2 and a locking body 3 and has the same configuration as that of the above-described conventional technique. More specifically, the hook 2 having a locking recess 2b in the upper portion is formed at the center. A rotating shaft 2a provided in the vicinity is pivotally supported by the vehicle body 9, and a cable 5 having an opposite end connected to a release lever 7 provided at a lower portion of a steering (not shown) is connected to the lower portion. Reference numeral 6 denotes a spring having one end locked to the lower end of the hook 2 and the other end locked to the vehicle body 9. The hook 2 is always attached to the locking body 3 by the spring 6. It is energized. The locking body 3 is a rod-shaped body extending in the left-right direction of the vehicle, and both ends thereof are fixed to the engine hood 4 with bolts.
Reference numeral 1 denotes a push-up member protruding from the hook 2, which is formed so that the engaging portion 1a abuts against the locking body 3 from below during the unlocking operation. The same members as those in FIG. 4 are given the same reference numerals.
[0008]
Next, the opening operation of the engine hood having the above configuration will be described. First, when the release lever 7 is operated (pulled toward the driver's seat), the cable 5 is pulled, the hook 2 rotates against the tension of the spring 6, and the hook 2 is unlocked from the locking body 3. . At this time, the engaging portion 1 a of the push-up member 1 comes into contact with the lower portion of the locking body 3. When the release lever 7 is further pulled and the hook is further rotated, the push-up member 1 operates to lift the locking body 3, and a gap is generated between the vehicle body 9 and the engine hood 4.
[0009]
Therefore, even if there is no part where the engine hood is caught, the engine hood can be easily opened by inserting the hand into the gap. For example, this operation may be performed by operating the release lever 7 with the left hand and lifting the engine hood with the right hand.
[0010]
Thus, even if the surface of the engine hood is smooth and there is no part to be caught, when the unlocking operation is performed, a gap is generated in the lower part of the engine hood, so that it can be easily opened. Furthermore, since it has a simple configuration in which a push-up member is provided on the hook, it can be implemented at a low cost.
[0011]
In the above embodiment, the push-up member protruding from the hook is in contact with the lock body locked by the hook to generate a gap, but the portion where the push-up member comes into contact is a lock body. There is no need to contact the engine cover so that a gap is generated between the engine cover and the vehicle body. In addition, the shape and configuration of each part may be changed as appropriate without departing from the spirit of the present invention.
[0012]
【The invention's effect】
As described above in detail, according to the first aspect of the present invention, when the unlocking operation is performed, a gap is generated in the lower portion of the engine hood, so that even an engine hood having a design that does not catch a hand can be easily opened. Can be operated.
[0013]
And since it is the simple structure which provided only the raising member in the hook, it can implement at low cost.
