[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forklift truck loading and unloading device in which a fork is prevented from swinging at a portion where a finger bar and a fork are engaged.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 5 and 6, a forklift truck has a vertically long lift bracket 1 mounted on a pair of left and right masts standing upright in front of a vehicle body.
Are mounted on the left and right lift brackets 1 at upper and lower sides, respectively, and the fork 3 is engaged with the finger bars 2. In this engaging portion, the fork 3 is engaged so as to be able to slide left and right along the finger bar 2.

[0003]

In the conventional cargo handling device for a forklift truck, since the engagement portion between the finger bar and the fork is in a loose fit state, the fork swings due to vibrations of the vehicle body during running and the finger. It collides with a bar and generates noise. The purpose of the present invention is to solve these problems.

[0004]

According to the present invention, in order to solve the above-mentioned problem, one end of the fork is in elastic contact with the rear surface of the vertical portion of the fork, and
Is in contact with the rear surface of the lower finger bar,
The upper side of the fork is pressed forward against the finger bar
The lower side of the fork is pressed rearward.
By providing the pulling member on the fork, the swing of the fork is suppressed to prevent the generation of noise.

[0005]

[Embodiment] A first embodiment of a forklift truck cargo handling device according to the present invention will be described with reference to FIGS. In a conventional cargo handling device, a fork 3
Pins 6 are respectively fixed so as to protrude right and left on the rear surface of the vertical portion near the upper portion where the finger bar 2 engages, and wire-shaped spring members 5 are respectively attached to the pins 6.
Is provided. The center of the spring member 5 is pivotally supported by the pin 6, one end of the spring member 5 is in elastic contact with the rear surface of the lower finger bar 2, and the other end is in elastic contact with the rear surface of the vertical portion of the fork 3. And the upper surface of the fork 3 is pressed forward against the lower finger bar 2 by being elastically contacted with the lower finger bar 2 and the vertical rear surface of the fork 3 as a fulcrum. 3, the lower side is pressed rearward.

Next, a second embodiment will be described with reference to FIGS. In a cargo handling device similar to the conventional one, a pin 8 is fixed via a block 7 near the upper portion of the vertical portion of the fork 3 where the finger bar 2 engages with the lower finger bar 2. A spring member 5 is supported. The spring member 5 is bent downward in a direction away from the fork 3, and is bent in the opposite direction at the tip of the spring member 5, and its tip is elastically contacted with the rear surface of the lower finger bar 2. A shaft 9 is attached to the other end in the width direction. A plate cam 10 is supported at one end of the shaft 9 in an orthogonal direction, and a hexagon bolt head-shaped projection 11 is formed on the plate cam 10. Have been. By rotating the projection 11 of the plate cam 10 with a spanner or the like to rotate the plate cam 10 to separate the other end of the spring member 5, the spring member 5 uses the contact portion of the pin 8 as a fulcrum. The lower finger bar 2 is pressed against the lower finger bar 2 by being elastically contacted with the lower finger bar 2 so that the upper side of the fork 3 is pressed forward and the lower side of the fork 3 is pressed rearward. is there.

Since the spring member 5 can easily release the operation of pressing the fork 3, the fork 3 can be slid left and right along the finger bar 2 as in the related art after the release. .

[0008]

[Effects of the Invention] As described in detail above, the present invention relates to a forklift truck cargo handling device in which one end of a forklift truck has a fork.
Elastic contact with the rear of the vertical part, the other end is the rear of the lower finger bar
To the finger bar below.
The upper side of the fork is pressed forward and the lower side of the fork is
The fork is provided with a spring
The fork allows the fork to be firmly supported by the finger bar via the spring member. Accordingly, when vibration occurs in the vehicle body, the swing of the fork can be suppressed, collision with the finger bar can be prevented, and generation of noise can be prevented. Moreover, in the spring member
The upper side of the fork forward against the lower finger bar
To fork and push the lower side of the fork backward.
Therefore, when placing luggage on a fork,
To increase the force of the fork and to further suppress the fork's swing.
Noise can be greatly reduced when transporting luggage.
You. Also, the spring member has one end behind the vertical part of the fork.
And the other end to the rear of the lower finger bar
Simplifies the pressing action of the spring member.
Can be released, fork along finger bar
The operation of sliding right and left can be easily performed.
