Frame construction

Claim 1

In an improved construction for a frame composed of hollow members anchored at the corner by a spring member, the improvement comprising: a. a generally hollowed spring member within the hollow members including i. a central rib portion, alignment means depending from the central rib portion, including an outwardly extending corner alignment member abutting the outer walls of the hollow members adjacent the corner, and an inner alignment member having feet abutting the inner walls of the hollow members adjacent the corner and then extending a distance therealong from the corner, ii. two yieldable arms depending from the central rib portion and received within the hollow members, each arm including a wall member abutting the outer walls of the hollow members, the arms spaced from and of greater length than the feet of the inner alignment member, the end of the wall member being further from the corner than the end of the feet of the inner alignment member; iii. a channel member secured to the end of the wall member, abutting the outer walls of the hollow members and extending inwardly toward the inner walls of the hollow members, the channel member having a foot defined at its inner end, extending toward but spaced from the feet of the inner alignment member and spaced from the wall member, b. securement means extending inwardly from the outer walls of the hollow members for engaging the channel members, displacing and placing the arms under stress in a spring-loaded condition, causing an engagement between the spring member and the hollow members c. said engagement causing formation of internal forces resulting from the engagement between the securement means and channel members, the spring member being spring-loaded and allowing application and adsorption of external bending forces, without damage to the frame.
