Embodiments and Examples of the Invention

 Hereinafter, the present invention will be described more specifically with reference to examples. FIG. 1 shows a forklift equipped with a strip curtain fouling prevention tool 1 according to an embodiment of the present invention. Since the forklift is the same as the forklift of FIG. 4 described above, the same reference numerals in FIG. 1 as those in FIG. 4 are assigned and the description thereof is omitted.

As shown in FIGS. 1 and 2A, the antifouling tool 1 has a rod-like push-back body 4 and a long plate-like fixing member having one end fixed to the push-back body 4. Arms 5 and 5 are provided.

The push-back body 4 is composed of a main body 2 made of a metal pipe and a contact body 3 made of a synthetic resin pipe having an inner diameter larger than the outer diameter of the main body 2. Further, the fixed arms 5 and 5 have a long plate-like shape, one end of which is welded and fixed to the intermediate portion in the longitudinal direction of the main body 2 constituting the push-back body 4 at a predetermined interval. Is bent in an inverted shape, and the other end is a fixing portion 6 having a mounting hole 61 formed therein.

As shown in FIG. 2 (B), the strip curtain antifouling device 1 is attached so as to cover the three abutting members 3 on the main body 2 made of a metal pipe. 3 are fixed to the main body 2 by welding one end of each of the two fixed arms 5 and 5 to the main body 2. Screws 7 and 7 are attached to both ends of the main body 2 so that the contact bodies 3 on both sides do not fall off from the main body 2. It can be easily configured by screwing it in a protruding state.

As shown in FIG. 1, the strip curtain fouling prevention tool 1 is obtained by fixing the fixing portion 6 of the fixing arm 5 to the upper end of the elevating stand e with bolts, nuts and the like. As a result, the pushing and retreating body 4 is attached to the forklift, and is in a state of being disposed substantially in front of the support mast d and the elevating gantry e in a substantially horizontal direction.

In this case, the main body 2 constituting the push-back body 4 is slightly longer than the width of the support mast d of the forklift, and both ends of the push-back body 4 are slightly higher than both side surfaces of the support mast d. It protrudes outward. Further, as described above, the fork f of the forklift also moves up and down with respect to the elevating gantry e, and the backrest m of the fork f rises upward beyond the upper end of the elevating gantry e. The forward projecting width of the body 4 is such that it does not hinder the upward movement of the backrest m.

When the forklift to which the antifouling tool 1 is attached passes through a doorway a of a warehouse having a strip curtain b as shown in FIG. Prior to the support mast d and the elevating stand e, the strip curtain b is pushed and retreated, and the strip curtain can pass through without being stained.

That is, in the strip curtain contamination preventing tool 1 attached to the forklift, as described above, the pushing and retreating body 4 is disposed and fixed substantially in the horizontal direction in front of the forklift support mast d and the elevating stand e. Further, since the pushing / retreating body 4 has a rod shape longer than the width of the elevating gantry e or the support mast d, the forklift to which the antifouling tool 1 is attached is provided at the entrance a of the warehouse to which the strip curtain b is attached. As shown in FIG. 3, the pushing and retreating body 4 comes into contact with the curtain b in front of the support mast d and the elevating gantry e and pushes it away.

Accordingly, the strip curtain b which is pushed away by the pushing / pulling-down body 4 is provided with the hydraulic cylinder g, the lifting / lowering chain j and the chain provided on the inside of the support mast d and the lifting / lowering stand e until the forklift passes. There is no contact with the lifting mechanism such as the gear h, the sliding portion between the lifting frame e and the support mast d, or the sliding portion between the fork f and the lifting frame e. It can effectively prevent fouling.

The antifouling tool 1 of the present embodiment is rotatably attached to the main body 2 of the push-back body 4 when the rod-like push-back body 4 comes into contact with the strip curtain b and pushes it away. Since each of the abutting members 3 abuts on the curtain b and can push back the curtain b while rolling on the surface of the curtain b, the friction between the curtain b and the pushing-back member 4 causes the curtain b to move. Damage can be prevented as much as possible, and the contamination of the curtain b can be more reliably prevented.

Further, the antifouling tool 1 has a push-back body 4 in which a metal pipe main body 2 is covered with a synthetic resin pipe abutment 3, and one end is fixed to the push-back body 4 main body 2. And a fixed arm 5 provided with a forklift fixing portion 6 at the other end, and the fixing portion 6 of the fixed arm 5 is attached to a forklift elevating platform e with bolts and nuts. By fixing and mounting, the rod-like push-back body 4 can be easily arranged and fixed along the horizontal direction in front of the elevating gantry e and the support mast d, and can be provided easily and inexpensively on a forklift. Can be done.

As described above, the strip curtain stain preventing tool 1 of the present embodiment can be configured simply and inexpensively, and can effectively prevent the strip curtain b from being stained.

The strip curtain antifouling device 1 according to the present invention is not limited to the above embodiment, and may be variously modified. For example, in the above-described embodiment, the pushing and retreating body 4 is constituted by the main body 2 of the metal pipe and the contact body 3 of the synthetic resin pipe, but the material may be any material. The pushing and retreating body 4 may be constituted only by the main body 2 and omitted. Further, the fixing portion 6 of the fixing arm 5 and other configurations may be appropriately changed without departing from the gist of the present invention. Further, in the above-described embodiment, the strip curtain contamination preventing tool 1 is attached to the upper end of the elevating gantry e, but the attachment location can be changed as appropriate.
