【Example】

 A first embodiment of an attachment device for a forklift truck according to the present invention will be described. As shown in FIG. 2, a plate part 3 on which a load to be transported can be placed, left and right fork claw insertion parts 4 fixed to the left and right of the lower part of the plate part 3 in the front-rear direction, and the plate part. 3, the plate portion 3 can be installed over the pair of left and right fork pawls 2 of the forklift truck, and the horizontal body 6 and the horizontal body 6 that extend horizontally in the front-rear direction. A vertical body 7 that extends upward at a substantially right angle from the rear end portion forms a plate shape bent in an L shape, and a load can be placed on the horizontal body 6.

The fork pawl insertion portions 4 are fixed to the left and right sides of the lower portion of the lateral body 6 of the plate portion 3, respectively, and as shown in FIG. 3, the lateral dimensions are slightly larger than the lateral width dimension of the fork pawls 2. From the bottom portion 8 having the above and the left and right side portions 9 having the vertical dimension slightly larger than the vertical thickness dimension of the fork claw, the cross section is an upward U-shaped section which is elongated in the front-rear direction, and is formed inside this. The fork claws 2 of the forklift truck can be inserted into the space 10 from the rear side. Further, the fork claw insertion portion 4 has a bottom portion 8 which is directed slightly obliquely forward and upward.

The locking portions 5 are provided on the left and right sides of the rear portion of the vertical body 7 of the plate portion 3, which is a position on the rear side of the position where the fork claw insertion portion 4 is fixed to the plate portion 3. Is. The locking portion 5 includes a pair of left and right base plates 12 that are spaced apart from each other by a dimension slightly larger than the left and right width dimensions of the fork claw 2 having a half-moon shaped hole 11, and the left and right base plates 12. As shown in FIG. 4, after inserting the fork pawl 2 of the forklift truck into the fork pawl insertion portion 4, it is inserted into the hole 11 of the base plate 12 of the locking portion 5, as shown in FIG. By inserting the pin body 13, the pin body 13 is brought into contact with the rear part of the fork claw 2 to prevent the fork claw 2 from coming out of the fork claw insertion portion 4.

By using the attachment device of the forklift truck configured as described above, when carrying a load, as shown in FIG. 5, when the fork pawl 2 is tilted forward, the plate portion 3 is laterally moved. The body 6 is directed forward and downward, and the front end of the lateral body 6 can be brought into contact with the ground. At this time, the fork claw insertion portion 4 fixed to the lower portion of the horizontal body 6 has a bottom portion 8 that is slanted so that it does not collide with the ground. As a result, it is possible to eliminate or reduce the step between the front end of the lateral body 6 of the plate portion 3 and the ground, and the operator can push the load and push the load to the side of the plate portion 3 without lifting the load. It can be loaded on the body 6 and can be unloaded from the horizontal body 6 of the plate part 3 while pushing the load.

In the plate portion 3, as shown in FIG. 6, the front portion of the lateral body 6 of the plate portion 3 is bent slightly downward so that the front end portion thereof easily contacts the ground. May be.

Next, a second embodiment will be described. As shown in FIG. 7, a plate part 3 on which a load to be conveyed can be placed, left and right fork claw insertion parts 4 fixed to the left and right of the lower part of the plate part 3 forward and backward, and the fork claw. The plate portion 3 can be installed over the pair of left and right fork pawls 2 of the forklift truck, and is formed from the lateral body 14 that extends horizontally in the front-rear direction. Therefore, a load can be placed on the horizontal body 14.

The fork claw insertion part 4 is fixed to the left and right sides of the lower part of the lateral body 14 of the plate part 3, and has a bottom part 15 having a lateral dimension slightly larger than the lateral width dimension of the fork claw 2. And the left and right side portions 16 having a vertical dimension slightly larger than the vertical thickness dimension of the fork claw 2 and an elongated U-shaped cross-section upward and backward, and the rear ends of the left and right side portions 16 are The plate portion 3 is formed so as to project rearward from the rear end thereof, and the hole portion 17 is formed therein. As in the first embodiment, the space portion 18 formed inside the hole portion 17 is formed from the rear side of the forklift truck. The fork claw 2 can be inserted, and the bottom 8 of the fork claw insertion portion 4 is directed slightly forward and upward.

The locking portion 5 includes a pin body 19 that can be inserted over holes 17 formed in the rear end portions of the left and right side portions 16 of the fork pawl insertion portion 4, respectively. After inserting the fork pawl 2 of the forklift truck, the pin body 19 of the fork pawl 2 is inserted into the hole 17 of the left and right side portions 16 of the fork pawl insertion portion 4 by inserting the pin body 19 of the fork pawl 2 into the fork pawl 2. The fork pawl 2 is prevented from coming out of the fork pawl insertion portion 4 by being brought into contact with the rear portion.

By using the attachment device of the forklift truck configured as described above, as in the first embodiment, when carrying a load, the worker pushes the load without lifting the load. It can be loaded on the lateral body 14 of the plate part 3 and can be unloaded from the lateral body 14 of the plate part 3 while pushing a load.

[Effect of device]

 According to the present invention, a plate-shaped plate portion that can be installed across a pair of left and right fork pawls provided on the front part of a vehicle body of a forklift truck, and the pair of left and right fork pawls can be inserted by being fixed to the lower portion of the plate portion. Attach the attachment device to the fork claw that consists of the left and right fork claw insertion parts and the locking part that prevents the fork claw inserted in the plate part or the fork claw insertion part that is inserted into the fork claw insertion part from coming out. This eliminates the need for a conventional operator to lift the luggage and load it onto the pallet or unload it when carrying a load, instead of pushing the load onto the plate. Alternatively, the load can be pushed off the plate while being pushed down, which reduces the burden on the operator during work and improves workability. Along with the attempt to above, from being damaged by dropping to the pallet on the ground and the luggage can be prevented. Further, according to the present invention, it is possible to eliminate the need for a pallet at the time of carrying a load, and it is possible to reduce the work cost.
