Workbench with four detachable legs

Abstract

A workbench includes two opposite sides each having a connection member mounted thereon. Four stationary members respectively mounted to two opposite ends of each of the two connection members. Four sleeves respectively mounted to two opposite ends of each of the two connection member and extending through the connection member and the stationary member. Four legs respectively inserted into a corresponding one of the four sleeves for supporting the top of the workbench.

1 . A workbench with four legs that are easily detached from the workbench after being used for a period of time, the workbench comprising:
 a top including two side walls respectively extending downward from two opposite sides thereof and each side wall having a vertical portion and a horizontal portion;   two connection members respectively fixed to an underside of the top and connected to a corresponding one of the two horizontal portions, each connection member having two opposite ends each having a first hole defined therethrough, each connection member having two first tubes extending from a top thereof and enclosing a corresponding one of the two first holes, a first flange inward extending from a tapered inner periphery of each of the two first tubes;   four stationary members respectively fixed to two opposite ends of each of the two connection members, each stationary member having a second hole defined therethrough, a second tube extending from a top of each of the tour. stationary members and enclosing the second hole, a second flange extending inward from a tapered inner periphery of each of the four second tubes, each second tube aligning with a corresponding one of the four first tubes;   four sleeves respectively inserted into the aligned first and second tubes, each sleeve having a tapered outer periphery relative to the aligned first and second tubes and a vertical inner periphery, two first grooves defined in the tapered outer periphery of each of the sleeves, the first and second flanges respectively engaged with a corresponding one of two first grooves to prevent the sleeve from overly extending toward the underside of the top of the workbench, two lips inward extending from the vertical inner periphery of each of the four sleeves; and   four legs respectively inserted into a corresponding one of the four sleeves, each leg having a plurality of second grooves defined in an outer periphery thereof, the plurality provided to receive the two lips of the corresponding sleeve to hold the leg in place for supporting the top of the workbench;   whereby:   the sleeves are made of flexible material so that the size of the legs can be made slightly larger than an inner diameter of the sleeves so that the sleeves are slightly expanded when the legs are inserted therein and the expansion of the sleeves makes the first and second flanges be securely engaged with the first grooves; and   the sleeves do not overly moved toward the top of the workbench even a heavy load is applied on the top due to the engagement among the first grooves, the first flange and the second flange, and the legs do not overly move toward the top of the workbench due to the engagement of the lips and the second grooves such that the legs can be easily separated/detached from the sleeves when needed.
