LEG AND TABLE HAVING THE LEG}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leg and a table having the leg, and more particularly, to a leg and a table having the leg, which can stably support the upper plate by firmly supporting the leg and preventing deformation such as bending.

Generally, the desk needed to read or write a book is composed of a top plate, a bridge supporting the top plate, and a drawer for storing various objects and documents. Depending on the position of the drawer, a number desk and a pumping desk In addition to being distinguished in recent years, such as a typing desk is sometimes produced for special purposes.

Also, depending on the material, it is divided into a steel material and a wood desk. However, in the case of a steel material desk, there is a problem such that corrosion can not be used for a long time due to corrosion or rusting and a drawer is twisted. , Legs and supporting parts are mainly made of steel.

Typically, such a wooden desk is manufactured by cutting a plate material formed by inserting a reinforcing material between a wood or an outer plate made of a pair of plywood to manufacture various types of upper plates, and a side plate is installed on both sides below the upper plate, A connecting box and a rear plate for blocking the rear portion of the side plate, and a support portion is provided at the bottom portion of the side plate to prevent shaking.

As for the desk, it has been proposed in Korean Utility Model Laid-Open No. 20-2008-0004080 (name of design: prefabricated table which can control the height of each leg).

In addition, the second upper beam 232 supports the upper plate 100 while being supported by the connection beam 210 through the second connection rib 234.

In addition, the second middle beam 233 is disposed in parallel with the connection beam 210 at the other side of the connection beam 210. In addition, the lower side of the second middle beam 233 is connected to and supported by the second lower beam 231. The upper side of the second middle beam 233 supports the second upper beam 232.

The second lower beam 231 and the second middle beam 233 are connected in various ways and the second middle beam 233 and the second upper beam 232 are connected in various ways.

For example, the second lower beam 231 may protrude a plurality of second lower fitting protrusions 235, or may protrude a second lower fitting protrusion 235 having a polygonal shape in plan view.

In addition, the second middle beam 233 forms a second lower fitting hole 237 to receive the second lower fitting protrusion 235 one-to-one below. Thus, the second lower beam 231 and the second middle beam 233 are assembled to prevent rotation, respectively.

In addition, the second upper beam 232 protrudes from the plurality of second upper fitting protrusions 236 or protrudes from one of the second upper fitting protrusions 236 having a planar polygonal shape.

In addition, the second middle beam 233 forms a second upper fitting hole 238 to receive the second upper fitting protrusion 236 one-to-one on the upper side. Thus, the second upper beam 232 and the second middle beam 233 are assembled to prevent rotation, respectively, arbitrarily.
