Description

[Detailed description of the invention] The present invention relates to a backrest device for a forklift.

An example of a backrest for a conventional forklift is shown in FIG. That is, in the figure, l is a fork, 2 is a mast, 3 is a fork carriage that is equipped with the fork l and moves up and down guided by the mast 2, and a pair of left and right lifts that go up and down along the mast 2 via rollers (not shown). It consists of a bracket≠, a pair of upper and lower finger bars 5 fixed to the rifted platform, and an integral backrest≦ fixed to the side of the finger <−r by tightening with bolt nuts. 7 is a lift cylinder, t is a chain wheel support fixed to the tip of the movable part of this lift cylinder 7, and ri is this support rvc.
A rotatably supported chain wheel, IO, is a lift chain that is suspended from this wheel 9, has a distal end connected to the fork carriage 3, and a proximal end fixed to a stationary part of the front cylinder 7. A pair of left and right forks l are attached so that their upper and lower ends are hooked onto finger bars, respectively, so that they can be used to carry loads on pallets. It also has the function of supporting cargo in places such as transport, and preventing cargo from collapsing.

However, such forklifts have had various problems as listed below.

(1) It is not possible to transport small items that are not loaded onto pallets.

(2) When transporting low-height cargo, the backrest remains fixed even though it is not necessary, so it obstructs the driver's forward view.

(3) The fork/fork is extremely dangerous because its two claws always protrude toward the front of the vehicle. The present invention was made by focusing on these conventional problems, and the main body of the backrest device The purpose of the present invention is to solve the above-mentioned problems by forming the backrest into a pallet shape, making the backrest main body rotatable around the base of the fork, and covering the upper surface of the fork in a horizontal state.

The embodiment shown in the drawings will be described below, with the same parts as the conventional one being given the same reference numerals. In FIGS. 2 and 3,
As before, the fork L has finger par 3 at its upper and lower ends.
It is attached in a hooked state. The main body // of the backrest device MVc is formed in the shape of a pallet. That is, the plate thickness is about 2.3 to 11. j All flat plate/
7 lunges on the outer periphery of /a excluding the vicinity of the base of fork l/
/l) is formed, and a plurality of through holes //c, //c, . There are 7 tips on both ends of the lower finger bar j.
Platen 1 that extends to near the base of the oak l. /2. /2
The base of is the mounting bolt/3. /3 is installed. Pins /Q, /Q are attached to both sides of the upper end of the pallet-shaped backrest body // by welding.

/Q is the platen) /Z, pin hole provided at the tip of /2 /3. /3 is rotatably inserted. As a result, the pallet-shaped hackrest main body l/ha can be rotated around the base of the fork l, forming a backrest device M, and as shown in FIG. It is meant to be covered. A bolt insertion hole 16 is bored in the side surface of the upper end of the pallet-shaped backrest body //, and on the other hand, when the pallet-shaped backrest body l/ is in a vertical state (
(See Fig. 3) A bolt hole /7 is formed at a position opposite to the bolt insertion hole /A, and a fixed head bolt /g inserted through the bolt insertion hole /6 can be screwed into this bolt hole 17. It has become.

Next to this configuration, in the case of transporting small bulk items, the second
As shown in the figure, if the pallet-shaped backrest main body /l is set in a horizontal state, small items can be transported in large quantities without a pallet by placing them on the pallet-shaped backrest main body //.

In this case, if the fixing bolt l is screwed into bolt hole /7, there is no risk of losing it.

On the other hand, in the case of transporting a large object, as shown in FIG. 7, the pallet-shaped backrest main body l/ is maintained in a vertical position, so that cargo handling work can be performed according to the same specifications as a conventional forklift.

As described above, the present invention has the following effects.

(1) Small bulk items can be easily transported without using pallets.

(2) In the work of transporting small objects, the backrest main body is not located where it should be conventionally, so good visibility can be obtained.

(3) Safety is improved because the backrest body functions as a safety cover that covers the fork.

(4) When working with the backrest main body in a vertical position, the front surface of the backrest main body is a smooth flat plate, so there is no possibility of damaging the cargo.

(5) Compared to conventional forklifts, it is capable of transporting loose items, cardboard items, heavy items, etc. for multiple purposes.
