ABSTRACT:
A collapsible work support device for use either as a work bench, or as a saw horse when used in conjunction with another such device. The device has an elongated beam used as the principal working member, which is placed on a separate support assembly consisting of a main support and two side supports hingedly attached thereto. The side supports are placed in an open position to cooperate with the main support to form a three-sided member for supporting the beam when in position for use. When the device is to be collapsed for storage, the top beam is removed, the side supports are folded into a closed position flat against the main supports, and the top beam is turned sideways and secured to the support assembly into the collapsed position. The device then becomes a compact unit that may be easily transported or stored.
