[0003]

[Problems to be solved by the present invention] Conventional stock car
There is no problem when transporting or storing luggage in a warehouse with loads, but when not in use, there is a drawback in that a storage space for the trolley is required. In the case where the pair of shelf frames is detachable from the cart so that they can be detached and stored when not in use, the cart, the pair of shelf frames and the shelf board are likely to fall apart, it is difficult to organize and set, and it is set when used. However, there was a disadvantage that it took time and effort.

The present invention has been made in view of the above-mentioned conventional drawbacks,
When not in use, the locking pieces of the shelf member can be supported in a suspended state by engaging with a pair of locking pieces formed on the shelf support bar of the shelf frame. It is an object of the present invention to provide a stock cart that can reliably prevent the protrusion from protruding to the outside. In addition, the present invention allows a shelf member or a movable shelf frame to be suspended and stored in a fixed shelf frame when not in use, and can be nested in this state.
The purpose is to provide a stock cart that can store the objects.

[0005] The above and other objects and novel features of the present invention will become more completely apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are merely for explanation and do not limit the scope of the present invention.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a truck and a pair of shelves each having a shelf support bar attached to a front end and a rear end of the truck. A pair of shelf frames, a pair of locking pieces protruding upward formed at portions near both ends of the shelf board support bar near one upper part of the pair of shelf frames, and located between the pair of shelf frames. An L-shaped shelf member that can also be used as a side frame serving as a shelf plate, and a U-shaped member formed at a position near both sides of both ends of the shelf plate member and engaged with the pair of locking pieces. A stock cart is constituted by two pairs of locking pieces bent in a shape.

[0007]

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