Abstract
A screen printing frame is formed with hollow extruded metal frame members joined at their ends by extruded metal interfitting connectors which are retained within the ends of their associated frame members by frictional engagement supplemented by a bonding agent. The force required to establish the frictional engagement is maintained in the preferred embodiment by elastic flexure of a bowed side wall on each connector arm. The structural members may have prefinished surfaces such as anodized surfaces and are joined together without welding as would mar such surfaces during the welding operation. The amount of metal used for the extrusions has been minimized for cost reduction and to obtain a lightweight structure. Grooves on the interfacing surfaces of the connector arms and the frame members cooperate to form an interstitial lattice which receives a bonding agent. Miter joints at the corners of the structure are sealed by corner webs on the connectors in combination with a bonding agent.
