[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery fixing device mounted on a battery-powered forklift.

[0002]

2. Description of the Related Art In a battery-powered forklift equipped with a battery as a driving source, after the battery is stored in a predetermined position, a stopper device provided on a frame of a vehicle body is manually operated to lock and lock the battery. Was.

As this stopper device, a rotary type or a pin insertion type is known.
FIG. 7 shows an example of the rotation type. In the figure, reference symbol S denotes a stopper pivotally attached to the vehicle body frame. When the stopper is rotated counterclockwise as shown by a solid line, the lock state is established, and the battery B can be prevented from falling off. The lock is released by rotating clockwise as shown by.

[0004] In the conventionally known manual stopper device as described above, after the battery B is mounted and stored, the stopper S may be forgotten to be applied. The battery B may move and jump out, causing an accident of falling off, which is extremely dangerous.

[0005]

SUMMARY OF THE INVENTION The purpose of the present invention is to solve the above-mentioned problems, and when a battery is mounted on a battery-powered forklift,
When the storage is completed, the stopper automatically operates to be in a locked state, thereby preventing the battery from accidentally jumping out and falling due to forgetting to apply the stopper.

[0006]

SUMMARY OF THE INVENTION The present invention provides a means for solving the above-mentioned problems. The invention provides a means for supporting a swingable stopper 5 via a pin P on a body frame 1 of a battery-powered forklift. A vertical contact plate 3 and a guide plate 4 having a horizontal oblique side protrude from one end of the battery 2, and the stopper 5 is normally held in the lock position a by its own weight. The battery forklift lifter 2 is pushed back to the open position B by the oblique side of the guide plate 4 and returned to the locked position a upon completion of the storage, engages with the abutment plate 3 and is automatically locked. The invention is based on the fixing device.

[0007]

Since the present invention has the above-mentioned structure, the stopper 5
Is always held in the locked position by its own weight,
When the battery 2 is pushed into the storage position when the battery 2 is mounted and stored, the battery 2 comes into contact with the oblique side of the guide plate 4 protruding horizontally at one end of the battery 2 and is pushed back to the open position B, and when the storage is completed. The contact with the guide plate 4 is released to return to the locked position, and the battery is automatically locked by engaging with the vertical contact plate 3, so that the battery falls due to forgetting to apply the stopper as in a conventionally known manual locking device. Accidents can be prevented.

1 to 6 show an embodiment of the present invention. 1 is a side view of a battery mounting portion showing a state in which a battery is stored in a vehicle, FIG. 2 is a front view thereof, FIG. 3 is a side view showing a main part of the present invention, FIG. 4 is a front view, and FIG. FIG. 6 is a partially enlarged side view showing a state where a guide roller is attached to a stopper.

In FIG. 1, reference numeral 1 denotes a body frame of a vehicle body, on which a battery 2 is mounted and housed, as shown in FIGS. That is, the battery 2
In order to inspect and maintain the battery, a battery receiving stand (not shown) is installed adjacent to the side of the vehicle body, the battery 2 is pulled out in the pull-out direction indicated by an arrow A in FIG. The battery 2 is pushed in the storage direction shown by the arrow and stored in a predetermined position.

Reference numeral 3 denotes a backing plate which projects vertically from one end of the battery 2 and 4 denotes a guide plate which also projects horizontally from one side of the battery 2. The guide plate 4 has a plane right-angled triangular shape, and the longer side of the two sides that are at right angles to each other is the battery 2,
The short side is fixed to the backing plate 3. The means for attaching the backing plate 3 and the guide plate 4 is optional, but is preferably fixed to the battery 2 by welding or other fixing means.

Reference numeral 5 denotes a stopper which is supported at an appropriate position on the frame 1 via a pin P so as to be able to swing (rotate). The stopper 5 is normally held by its own weight at a lock position a shown by a solid line. 1 is in contact with the upper surface,
b engages with the backing plate 3 to lock. Reference numeral 6 denotes a battery roller which is supported in parallel on the frame 1 and serves as a guide roller when the battery 2 is pulled out and pushed in. Reference numeral 7 denotes a roller provided on the base-side projecting portion 5b of the stopper 5, which is provided as necessary as described later.

With the above-described structure, the battery 2
Is pulled out for inspection and maintenance and is on the cradle,
The stopper 5 is held at the solid line position A by its own weight.
In order to store the battery 2 in this state, the storage direction B
(Perpendicular to the plane of the paper in FIG. 3).
And the guide plate 4 is sequentially a → as shown in FIG.
Take the position of b → c, and stop 5 with guide plate 4
Are sequentially displaced from the stage in contact with the hypotenuse, and rotate counterclockwise in FIG. 3 with the pin P as a fulcrum.
It reaches the position b shown by the two-dot chain line, but when the storage is completed,
The contact with the guide plate 4 is released and the guide plate 4 returns to the position indicated by the solid line by its own weight, and the projection 5b engages with the backing plate 3 and is automatically locked. When pulling out the battery 2 from the storage position, the stopper 5 may be manually pulled up to the position B to release the lock, and then pulled out in the arrow A direction.

As shown in FIG. 6, a guide roller 7 corresponding to the guide plate 4 is provided on the overhang portion 5b of the stopper 5.
Is provided, the contact resistance between them can be reduced, and the rotation of the stopper 5 can be performed more smoothly when the battery 2 is stored.

[0014]

According to the present invention, a swingable stopper 5 is pivotally supported on a frame 1 via a pin P, and one end of a battery 2 has a vertical contact plate 3 and a horizontal oblique side. A guide plate 4 is protruded, and the stopper 5
It is always held in the lock position a by its own weight,
When the battery 2 is mounted and stored, the guide plate 4 is pushed back to the open position B by the oblique side, and when the storage is completed, the guide plate 4 is returned to the lock position A and engages with the abutment plate 3 to be automatically locked. The battery is automatically locked when it is pushed in, while it is manually opened when it is pulled out.This prevents the battery from accidentally popping out due to forgetting to apply the stopper.The lock is automatic and the opening is manual, so it is always on the safe side. Works and is extremely safe.
