Abstract
Abstract A picture frame with a rabbeted inner periphery, forming an abutment for a stack including a glass pane, a decorative insert and a backing plate, has an inner peripheral groove in a plane paralleling the rabbet and another groove transverse to that plane close to the outer edge of the rear face of each of its members. One or more clips of elastic material (metal or plastic) engage each frame member from the rear, each clip having a channel profile with mutually perpendicular lips snap-fitted into the inner and outer grooves and further having at least one dovetailed transverse mortise open toward the interior and the rear of the frame. Each clip is engaged by at least one elbow of similar elastic material with two arms adjoining each other at an acute angle, either of these arms fitting tightly into a corresponding mortise while the other arm bears resiliently upon the rear surface of the stack resting against the rabbet. The clips may be straight bars, slidably fitted onto individual frame members, or angle pieces engaging the corners of the frame.

Claim 1
Independent Claim
214 words
An assembly for mounting a flat carrier of rectangular outline bearing a message to be displayed, comprising: a four-sided frame with a rabbeted inner periphery forming a planar abutment for a front surface of said carrier, said frame being provided on at least two opposite sides with an inner peripheral groove extending parallel to and rearwardly of the plane of said abutment and with a transverse groove extending on a rear face of said frame parallel to said inner periphery; a plurality of clips of elastic material engaging said frame on said opposite sides, each of said clips overlying part of said rear face and having a channel profile with mutually perpendicular first and second lips respectively entering said inner peripheral groove and said transverse groove of the corresponding frame side, each of said clips being further provided with at least one transverse mortise with undercut edges open to the interior and to the rear of the frame; and a plurality of detachable elbows of elastic material respectively engaging said clips, each of said elbows having two arms adjoining each other at an acute angle, one of said arms being frictionally fitted from behind into a mortise of the respective clip while the other arm resiliently bears upon a rear surface of said carrier.
