Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in attachments for cargo handling vehicles.

2. Description of the Related Art Conventionally, there are attachments for a forklift truck, which is a cargo handling vehicle, such as a pallet fork, which is provided with a cargo loading surface and can be used during cargo handling.

However, with such conventional attachments,
This was done with a focus only on the usability of the cargo handling vehicle, and the attachment does not serve any purpose when removed from the cargo handling vehicle. In small businesses, etc., such attachments are convenient when using a cargo handling vehicle, but removing them and storing them when not in use is wasteful and requires space, so they are practically difficult to use. There was.

The present invention has been made by focusing on such conventional problems, and aims to solve the above problems by allowing an attachment having a load placement surface to be used as a transport vehicle when separated from a cargo handling vehicle. The purpose is

In order to achieve such an object, in the present invention, in an attachment for a cargo handling vehicle having a cargo loading surface on the main body, a carriage of the cargo handling vehicle is provided which is movable up and down on the rear part of the attachment and the back surface provided upright on the main body. In addition to providing a detachable part that can be engaged and detached, wheels for transportation are provided below the cargo loading surface of the main body, and when the cargo handling vehicle is used, it is attached to the carriage, and when the cargo handling vehicle is not in use, it can be quickly removed and moved. It is designed so that it can be used as a transport vehicle that can be moved by wheels.

Hereinafter, one embodiment of the present invention will be described based on the drawings. Note that similar parts in each embodiment are designated by the same reference numerals, and redundant explanation will be omitted.

1 to 3 show a first embodiment of the present invention, in which an attachment (3) is removably attached to a carriage (2) of a cargo handling vehicle (1), which is a forklift truck.

The carriage (2) is the mast (11) of the cargo handling vehicle (1).
The lift bracket (2 is supported by the mast aυ,
A carriage frame (C) is solidly supported by the lift bracket (221), and the carriage frame (C) is fixedly supported by the side frame plate (24) H.
A fork support bar (c) is passed over the upper part of the fork support bar (c), a reinforcing plate to which the lift bracket (2) is fixed is passed below it, and a lower frame plate to which the lift bracket is fixed in the same way is placed below it. (b) will be handed over.

Attachment 3) has a back part (to) that serves as a handle when used as a transport cart, which is provided at the rear end of the main body C3 having a cargo placement surface (3υ), and the back part (to) has two ends. A handle pipe field is passed between the upper ends of the support leg 341.(34), and a connecting member (support) is passed below it,
The base height (3'n) of the supporting legs (34), (34) is supported so as to be able to be raised and lowered via the axis side 1 country on the support protrusions (to), (to) provided protruding from the body part country. A stopper (41) is provided on the base (37), and a stopper receiving part (4υ is provided, 4 stopper t41) and a stopper receiving part are provided on the support protrusion (to) to catch the stopper when the back part is raised. (4υ is a screw that holds the back part in an upright state (4υ allows for screw connection.
1) Moving wheels 143 below. +Q... is attached, and one of the moving wheels (43, H has a brake (
44) are provided. Then, a locking/disengaging member (51) is fixed to the handle pipe +351 made of the rear part, and the main body part 4
The pressing flange 6'2I at the rear end and the engaging/disengaging member (51) form an engaging/disengaging portion. That is, in the lower part of the engaging and disengaging member (b), a disengaging groove 53) that engages with the fork support barge 9 of the carriage (2) is formed, and a pressing flange 62 is formed.
1 faces rearward and is in contact with the lower frame plate (27) of the carriage (2).

In the attachment (3) having the above configuration, when using the attachment, the stopper (40) and the stopper receiving part (4υ) are in contact with each other in an upright state, and the screw (40) is fixed by boiling so that it does not fall down. , Load the luggage onto the wheels (431 is attached, so it can be moved as is, and the loading surface is 0]),
It can be used as a transport cart by holding the handle pipe 05), and after lowering the carriage (2) sufficiently, as shown in the second section, move the fork support bar (2ω) to the engaging and disengaging member 6.
If you lift the attachment (3) by aligning it with the engagement/disengagement groove (5) in 1), the pressing flange (broom) of the attachment (3) will come into contact with the lower frame plate of the carriage (2), and it will be lifted further. If so, the attachment (3) is attached to the carriage (2) and can be raised and lowered together with the cargo handling vehicle (
1) It can be used for cargo handling. Attachment (3) can be removed by reversing the procedure.

As shown in Fig. gitfl, the fork u314 can be laid down to the side of the cargo handling vehicle (1) so as not to get in the way. Furthermore, in this embodiment, since the engaging/disengaging member l51) is provided on the upper part of the back surface, it is easy to see and remove it from the carriage (2).

FIGS. 4 and 5 show a second embodiment of the present invention, in which a T-shaped engaging/disengaging member 6υ is fixed to a connecting member (36) made of the back surface.

6 to 8 show a third embodiment of the present invention,
1) of the engaging/disengaging member is made movable relative to the handle pipe field,
The engaging/disengaging member 6υ can be fixed to the handle pipe (39) by a threaded rod 551 rotated by a lever (54), and a connecting member (a downward hook member 66 at 361) is fixedly attached to the hook member (support). on the bottom frame plate of the carriage (2) (
27), and the connecting member (end) is pressed against the lower frame plate (5) instead of the pressing flange 5 of the above embodiment, and the engaging/disengaging member 6υ is made movable. Therefore, even if the centers of the cargo handling vehicle (1) and the attachment (3) are misaligned, they can be hooked to the center of the carriage (2) by adjusting the engaging/disengaging member 51). , the connection member (to) and the lower frame plate (27) will not separate, and the attachment (3) can be stably mounted on the carriage (
2) It has the advantage of being able to be installed.

FIG. 9 shows a modification of the structure for fixing the engaging and disengaging member 51), in which a chamfered portion 57) is formed on the handle pipe 09, and after being pushed by the threaded rod 5!19, the engaging and disengaging member 6υ rotates. I tried not to do that.

Fig. 10 shows another modification of the structure for fixing the engaging/disengaging member 51), in which a sharp corner 6 mark is formed at the tip of the threaded rod (G), and a sharp corner (6) is formed on the handle pipe (to). A square groove 59 is formed to fit into the locking member (51) so that the engaging/disengaging member (51) does not rotate.

According to the attachment according to the present invention, the attachment can be used as a transport vehicle and can be quickly attached to and detached from the carriage of a cargo handling vehicle.
It can be selectively used as part of a cargo handling vehicle or as a transport vehicle as needed, and can be effectively used even in small-scale businesses.
