Abstract

PURPOSE:To store a number of stock carts in a small space by engaging locking pieces of a shelf plate member with a pair of locking pieces formed on a shelfplate supporting bar of a shelf frame in a suspending condition to prevent the locking pieces from being projected outward of the locking pieces. CONSTITUTION:A truck having casters and capable of nesting consists of a trapezoidal frame 2 with its rear part open, a fixed shelf frame 15 of the rear end part having each shelf plate supporting bar, and a movable shelf frame 23 which is same widthwise and small in height, and removable. A shelf plate member 31 which is commonly used as a side frame is used as a shelf by being supported by a shelf plate supporting bar 17 of the fixed shelf frame 15 and a shelf plate supporting bar 25 of the movable shelf frame 23, and suspended from the outside of the fixed shelf frame when not in use by engaging hook- shaped locking pieces 34, 34 with the locking pieces 20, 20. Then, the movable shelf frame 23 is removed from the truck, and arranged along the inner surface of the fixed shelf frame 15, and suspended therefrom by locking nesting hooks 28, 28 with the shelf plate supporting bar 17 on the highest part, preventing the locking pieces from projecting outward.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stock cart used for carrying and carrying luggage and for storing and storing luggage in a warehouse.

[0002]

2. Description of the Related Art A conventional stock cart is a dolly to which casters are attached, a pair of shelf frames attached to the front and rear parts of the dolly, and a shelf whose both ends are supported by the pair of shelf frames. It is composed of a board.

[0003]

[Problems to be Solved by the Invention] Conventional stockcar
There is no problem when transporting or storing in a warehouse where luggage is loaded, but there is a disadvantage that a storage space for a trolley is required when not in use. In addition, it is difficult to organize the dolly, the pair of shelf frames, and the shelves that can be detached and stored when not in use because the pair of shelf frames can be detached from the dolly, and it is difficult to order and set them when using. There was a drawback that it was troublesome.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
When not in use, the locking pieces of the shelf plate members can be supported in a suspended state by engaging with the pair of locking pieces formed on the shelf plate support bar of the shelf frame. The purpose of the present invention is to provide a stock cart that can surely prevent the protrusion from protruding into a hindrance. Further, according to the present invention, a shelf board member or a movable shelf frame can be suspended and stored in a fixed shelf frame when not in use, and nesting can be performed in this state.
The purpose is to provide a stock cart that can store carts.

The above and other objects and novel features of the present invention will be more fully apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are for explanation only and do not limit the scope of the present invention.

[0006]

In order to achieve the above object, the present invention has a pair of carriages and a pair of shelf support bars mounted so as to face the front and rear ends of the carriages. Of the shelf frame, a pair of upwardly projecting locking pieces formed at a portion of the pair of shelf frames near both ends of the shelf support bar near the top, and located between the pair of shelf frames. And a U-shaped member, which is formed on both sides of both ends of the shelf member and which engages with the pair of locking pieces, is bent into an L shape. A stock cart is composed of two pairs of locking pieces.

[0007]

In the stock cart constructed as described above, the pair of locking pieces formed on the shelf supporting bar of the shelf frame does not project outward from the shelf frame, and the pair of engaging pieces are engaged. The locking piece of the shelf board member can be engaged with the stop piece to support it in a suspended state.
