DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cart for transporting goods loaded on pallets in a distribution center, a factory, a warehouse or the like.

[0002]

2. Description of the Related Art Conventionally, in a distribution center, a factory, a warehouse, or the like, as a cart for transporting loads loaded on pallets, a pallet on which loads are loaded as shown in a perspective view of FIG. A main plate 15 having a flat plate shape for mounting is provided. Four self-propelled wheels 16 are attached to a lower portion of the main plate 15, and a downward U-shaped handrail body 17 is fixed to one end of the main plate 15. I was In such a cart, the pallet on which the load is placed is placed on the main plate 15, and the load is conveyed by the operator pushing or pulling the handrail body 17.

[0003]

In such a conventional cart, the main plate on which the pallet on which the cargo is placed is placed in a flat plate shape, so that the area occupied by the main plate is large, and the cart is large. There is a problem that a large storage space for storing the cart is required when storing the cart. Furthermore, after a large number of luggage is transported using a large number of trolleys, when collecting empty trolleys by truck etc., a large number of trolleys may be loaded on the truck bed by the main plate with a large occupied area. There was also a problem that it could not be done. An object of the present invention is to solve these problems.

[0004]

According to a first aspect of the present invention, there is provided a foldable frame, a self-propelled wheel is mounted on a lower portion of the frame, and a pallet on which a load is placed is mounted on an upper portion of the frame. Trolley with a pallet guide body.

According to a second aspect of the present invention, in the first aspect, the frame is a hand cart having a parallel link formed by axially attaching two elongated main frames and two elongated link plates. I do.

According to a third invention, in the first or second invention, there is provided a hand cart having a bar-shaped handrail attached to one end of a frame.

[0007]

[Operation] According to the first or second or third invention,
By making the frame foldable, when folded,
The occupied area of the cart can be reduced, and a large storage space for storing the cart can be eliminated when the cart is stored.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a hand truck according to the present invention will be described. As shown in the plan view of FIG. 1 and the side view of FIG. 2, the cart has a frame 1 that can be folded, and the frame 1 is a main frame that is elongated in the front and rear directions in two parallel traveling directions. 2 and two parallel thin plate-like link plates 4 which are attached to the main frame 2 via a rotary shaft 3 via a rotating shaft 3 to form a parallel link. In the above, the two link plates 4
The main frame 2 of the book is folded close to the main frame. A hole is formed in each of the main frame 2 and the link plate 4, and a fixing knock pin 5 is inserted therein to fix the main frame 2 and the link plate 4 so that the frame 1 is not folded. To A downward U-shaped bar-shaped handrail 6 is attached above the rear ends, which are the front and rear ends of the two main frames 2 in the frame 1, and the handrail 6 also rotates with respect to the main frame 2. Make it freely attachable and removable.

A self-propelled wheel 7 is attached to a lower portion of each of the two main frames 2 of the frame 1 before and after the main frame 2. In addition to the caster wheel 8, the one attached to the rear side of the main frame 2 is a swivelable caster wheel 9.

A pallet guide 10 for fitting a pallet on which luggage is placed is mounted on each of the upper portions of the two main frames 2 of the frame 1. The pallet guide 10 is attached to the front and rear ends of the main frame 2. L-shaped brackets are fixed to each other, and the distance between the front and rear pallet guide bodies 10 is set to be the same as the outer dimension of the pallet on which the load is placed. Thus, when the pallet is placed on the frame 1, the pallet guide 1 attached to the front and rear of the main frame 2 in the frame 1
0 is inserted so as to sandwich the outside of the pallet.

In such a hand cart, the pallet on which the load is placed is placed on the frame 1 so as to fit into the pallet guide body 10, and the worker pushes or pulls the handrail body 6 so that the load is reduced. Can be transported.

On the other hand, at the time of storage without carrying the luggage, as shown in the explanatory view of FIG. 3, the two link plates 4 and the handrails 6 of the frame 1 are folded down to form the two main frames 2. And the frame 1 can be folded down so that the occupied area can be reduced, so that a large storage space for storing the push cart can be eliminated when the push cart is stored. Further, by removing the handrail body 6 as needed, it is possible to further reduce the size. By making the carts small and compact in this way, a large number of carts can be used to transport a large number of luggage, and then, when collecting empty carts by trucks, a large number of carts can be placed on the truck bed. A push cart can be loaded, and work can be performed efficiently.

Further, since the frame 1 is formed in a parallel link shape from the two main frames 2 and the two link plates 4, the number of parts can be reduced and a simple structure can be achieved. The operation can be performed smoothly.

[0014] The push cart according to the present invention includes:
The handrail body 6 is not limited to the one described in the above-described embodiment.
Was attached, as shown in the side view of FIG.
The handrail 6 may not be attached to the main frame 2, and the connecting tool 11 may be attached to the front and rear of the frame 1 so that the handrail can be connected to another hand cart. Further, as shown in the side view of FIG. 5, the front and rear lengths of the main frame 2 are shortened, and a pallet guide body 10 is fitted to the front and rear of the main frame 2 so as to sandwich the inside of the pallet. May be used. Further, as for the self-propelled wheels 7 attached to the main frame 2, the front side is a fixed caster wheel 8 and the rear side is a swivel caster wheel 9, but these may be arranged in reverse. Alternatively, all self-propelled wheels may be fixed caster wheels 8 or swivel caster wheels 9.

[0015]

According to the present invention, since the frame is foldable, the occupied area of the cart can be reduced when the frame is folded. When the cart is stored, a large storage for storing the cart is provided. Space can be made unnecessary, and after loading a large number of luggage using a large number of carts, loading a large number of carts into the truck bed when collecting empty carts by truck etc. Work can be performed efficiently.
