BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. Generally, the forklift 1
As shown by the broken line in FIG. 9, a pair of left and right L-shaped lifts 2 that move vertically are provided on the front surface of the vehicle. On the other hand, as shown in FIG. 2, the extension sheath fork 3 integrally has a mounting piece 3c in which a pin hole 3b is formed at the base end of a hollow sheath body 3a, and is attached to the horizontal fork 4 of the lift 2 of the forklift 1. It is used by fitting on the outside.

In the present invention, the above extension sheath fork 3 is classified by length.
The storage device 5 is stored at intervals and stored in the horizontal fork 4 of the forklift truck 1 in an easily attachable / detachable state. The storage device 5 is attached to a rack body 6 having a sheath fork storage rack and a proper position in the depth of the storage rack. Depth stopper 7 and a pair of left and right positioning members 8a, 8b attached to the front end of the storage rack
Is equipped with.

The rack body 6 is composed of upright columns 9 made of steel or the like.
In addition, horizontal storage shelves in which a vertical frame 10 and a horizontal frame 11 made of the same material are joined are formed in a multi-tiered manner, and the extension sheath fork 3 is placed in the depth direction of the storage shelves.

The depth stopper 7 is made of a frame of L-shaped steel or the like having a predetermined stand-up locking dimension, and is installed in the lateral direction between the vertical frames 10 and 10 of the storage rack. And
The fixed position of the depth stopper 7 is set according to the length of the extension sheath fork 3 placed on the storage rack.

The depth stopper 7 may be mounted between the vertical frames 10 and 10 such that the position thereof cannot be changed, but preferably, the fixing position can be changed along the vertical frame 10 according to the length of the sheath fork 3. Configure Therefore, in the illustrated embodiment, as shown in FIGS. 3 and 4, a slide engaging portion 7b that slides along the vertical frame 10 is integrally coupled to the end portion of the locking frame 7a of the depth stopper 7, and this slide is performed. The engaging portion 7b is provided with a position fixing means 7c such as a tightening bolt for the vertical frame 10 so that the depth stopper 7 can be installed at any position of the vertical frame 10 so that the position can be changed.

The pair of left and right positioning members 8a, 8b are the holding positions of the extension sheath fork 3 placed on the storage shelf and the left and right rising pieces 12a, 12b for restricting lateral movement (lateral displacement).
And a locking member 14 having a front stopper 13 that locks the lower front end edge of the sheath fork 3 placed on the storage rack, with a size corresponding to the interval between the left and right horizontal forks 4, 4 of the forklift. And is fixed to the frontmost horizontal frame 11 of the rack body 6.

As shown in FIG. 5, the positioning members 8a and 8b may be fixed to the horizontal frame 11 such that the locking member 14 is aligned with the space between the horizontal forks 4 and 4 but cannot be changed in position. Since the spacing between the forks 4 and 4 varies depending on the model of the forklift, it is desirable that the forks can be commonly used for these models. Therefore, FIG. 6 and FIG.
The positioning members 8a, 8b are formed by integrating the locking member 14 with a slide frame 15 slidably fitted to the horizontal frame 11 with a coupling frame 16, and tightening bolts or the like attached to the slide piece 15. The position fixing means 17 can fix the horizontal frame 11 at an arbitrary position so that the position can be changed.

Thus, as shown in FIG. 1, the storage device 5 has a storage section for each storage rack of the rack body 6 which is divided into the length of the sheath fork 3 and the width of the left and right horizontal forks 4, 4. It is formed. The storage section of each storage shelf should be able to distinguish the length of the sheath fork from the width of the fork by using different colors and symbols.

When the extension sheath fork 3 mounted on the forklift 1 is stored in a predetermined position of the storage device 5, as shown in FIGS. 7 and 8, after uncoupling the sheath fork 3, the extension sheath fork 3 is removed. Push the mounted horizontal forks 4 and 4 to the depth stopper 7 of the predetermined storage rack, and position the positioning member 8a,
8b, and it is put down on the storage rack so as to fit between the rising pieces 12a and 12b. When the forklift 1 is retracted in this state, as shown in FIGS. 9 and 10, the sheath fork 3 is locked by the front stopper 13 of the positioning members 8a and 8b and stored at a predetermined position on the storage rack. In the embodiment shown in FIG. 1, the sheath forks 3 and 3 are stored in the second storage rack from the top with a horizontal fork width of the forklift 1.

On the other hand, the horizontal forks 4, 4 are connected to the sheath fork 3,
When mounting the forklift 3, the left and right horizontal forks 4, 4 of the forklift 1 are inserted into the pair of sheath forks 3, 3 placed on a predetermined storage rack of the rack body 6, and then slightly lifted to retract the forklift 1. Then, the sheath fork 3,
3 is pulled out while being mounted on the left and right horizontal forks 4, 4.

In the illustrated embodiment, one set of storage shelves is provided for each storage rack, but a plurality of pairs of positioning members 8a, 8b are attached to one storage rack to provide a plurality of storage racks. A storage section can be provided. Further, since the gap between the upper and lower storage shelves may be slightly larger than the thickness of the sheath fork 3, the rack space can be efficiently used.

[0119]

[Effect] In the extended sheath fork storage device of the present invention, since the sheath forks are stored in an organized manner according to their length and width of the forklift, space can be saved and the sheath fork can be detached while operating the forklift. As a result, work efficiency is significantly improved.

By making the depth stopper and the positioning member slidable so that the position can be changed, the storage device can be utilized for various sheath forks.
