ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cart, and more particularly, to a cart for transportation, which is easily assembled.
2. Background of the Related Art
A cart is used for various purposes. Especially, it is mainly used as a means for carrying food in restaurants or hotels. The cart is widely used in America so that lots of carts produced in Korea are exported to America.
A conventional cart
1
that has been manufactured and sold in Korea and America so far, shown in
FIG. 1
, is constructed in a manner that a plurality of trays
10
each of which has frame wall
11
, leaving only one side open, are joined with a vertical supporting member
20
, which is bent at right angle, using bolts
21
and nuts. A handle
30
is also joined with the supporting member
20
using the bolt
21
by means of a handle support
31
.
Accordingly, the conventional cart
1
has problems that its manufacturer should punches bolt joint holes and its importer has a cumbersome process of assembling the components of the cart using bolts
21
. Furthermore, since the bolts
21
are exposed to the outside, it spoils the beauty of the cart. This deteriorates competitiveness in terms of design.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to a cart that substantially obviates one or more problems due to limitations and disadvantages of the related art.
An object of the present invention is to provide a cart for transportation, which has a beautiful appearance and is easily assembled without having a separate tool in such a manner that components such as trays, supporting members, a handle and wheels are joined together using a connecting member having insertions formed at both ends thereof instead of bolts.
It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
