[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trolley to which a shelf board can be attached and used.

[0002]

2. Description of the Related Art Conventionally, a truck of this type has a truck body on which casters are mounted, a pair of shelf frames detachably attached to both ends of the truck body, and both ends of the pair of shelf frames are detachable. It is composed of a shelf board that can be mounted as possible.

[0003]

When the conventional cart is not used, a shelf frame is detached from the cart body when the cart is not used, and the cart is stored in a state of standing against a wall surface of a storage room. For this reason, there were drawbacks that the bogie main body and the shelf frame were separated and had to be searched during use, and the storage space became large.

The present invention has been made in view of the above-mentioned conventional drawbacks,
It is an object of the present invention to provide a bogie that can be stored in the height of the bogie main body while being able to be locked to the main body of the bogie at the time of storage so as to prevent the storage space from falling apart. .

[0005]

In order to achieve the above-mentioned object, the present invention provides a rectangular base plate, a pair of fixed casters mounted on a bottom surface near both sides of the center of the base plate, and the base. A trolley comprising a pair of free casters attached to bottom portions near both sides of both ends of the plate, and a pair of shelf frame support pipes respectively attached to bottom portions near both sides of both ends of the base plate. In a bogie comprising a main body and a pair of shelf frames removably attached to a pair of shelf frame support pipes of the bogie main body, the bogie when the pair of shelf frames is not used, A truck is constituted by a fixed caster storage portion and a shelf frame support pipe storage portion on the pair of shelf frames so as to be able to abut on the bottom surface of the main body.

[0006]

In the truck constructed as described above, when not in use, the shelf frame can be locked to the fixed casters and the free casters of the truck body which stands up.

[0017]

[Effects of the present invention] As is clear from the above description, the following effects can be obtained in the present invention.

(1) A rectangular base plate, a pair of fixed casters mounted on a bottom portion near both sides of the center of the base plate, and mounted on bottom portions near both sides of both ends of the base plate, respectively. A pair of free casters, a bogie body comprising a pair of shelf frame support pipes respectively attached to the bottom portions near both sides of both ends of the base plate, and a pair of shelf frame support pipes of the bogie body. In a trolley comprising a pair of shelf frames removably mounted and projecting upward from the trolley body, the pair of shelves are configured so that the pair of shelf frames can be abutted on the bottom surface of the trolley body when not in use. Since the fixed caster storage section and the shelf frame support pipe storage section are formed on the frame, when not in use, remove the pair of shelf frames from the bogie body,
The trolley body can be engaged with a pair of fixed casters of the trolley body standing against a wall surface or the like to be positioned so as to contact the bottom surface of the trolley body. Therefore, many carts can be stored and stored in a small space.

(2) By the above (1), the pair of shelf frames can be locked to the bogie main body during storage so as to contact the bottom surface of the bogie main body, so that the bogie main body and the pair of shelf frames are separated. It can be stored in a tidy condition without becoming tidy. Therefore, it is possible to easily set and use the used state without looking down the shelf frame or the like at the time of use.

(3) According to the above (1), it is only necessary to form the fixed caster storage section and the shelf frame support pipe storage section on the pair of shelf frames, so that the embodiment can be easily implemented.

(4) According to the above (1), a pair of shelf frames can be stored within the height of the carriage body even during transportation, so that many carriages can be stored and transported in a small space. Therefore, it can be efficiently transported at a low transportation cost.

(5) Claim 2 has the same effect as (1) to (4).
