Frame, more particularly for a picture
First Claim
1. A frame for a picture comprising:
- profiled rails joined together at the corners of the frame by means of corner-connectors, each of said rails comprising a cavity and two webs extending in the longitudinal direction of the rail, and said two webs having an opening between them also extending in the longitudinal direction of the rail, said cavity being formed from a substantially U-formed portion of the profiled rail comprising of rearwardly directed legs each carrying one of said two webs, each web projecting laterally toward the web carried by the other leg ,each of said corner-connectors comprising two plugs formed integrally with each other in a single piece, each plug being inserted from an end inside the cavity of a rail,at least one of the webs comprising a retaining element projecting rearwardly behind the rear surface of said at lest one web,each plug comprising in the vicinity of said retaining element a resilient tongue with a free end which extends outwardly from the cavity through the opening between said two webs, said tongue being formed integrally with the plug and having a width which is at the most equal to the width of said opening,at least one laterally projecting hook element being provided at said free end of the tongue, said hook element extending outside said cavity and overlying said rear surface of said at least one web, said tongues and lateral hook elements having a maximum width no wider than the width of said plugs, andmeans for locking said hook element to said retaining element.

Abstract
A frame, more particularly for a picture, comprises profiled rails which are joined together at the corners of the frame by a corner-connector. Each corner-connector comprises two plugs arranged respectively in a cavity in each profiled rail, and each of the cavities comprises an opening extending in the longitudinal direction. The object to be achieved is a functionally reliable joint between the profiled rails which is simple to produce and can easily be released when required. To this end, each plug comprises a tongue which passes through the opening in the cavity and which engages, by means of a hook element or the like, behind a retaining element. A retaining element of this kind is arranged on at least one web of the profiled rail.

8. A frame according to claim I, wherein the leg of profiled rail (2) located at the outer margin of the frame carries an L-shaped leg (56) extending forwardly and laterally toward the Center of the frame, said cavity (14) and said corner connectors comprising the plugs (16, 18) are arranged behind the outer edge of a member (52) enclosed by the frame, and the outer margin said enclosed member (52) is overlapped in front only by the laterally extending portion of the L-shaped leg (56).
- 12. A frame comprising a plurality of profiled rails joined together by corner connectors to form corners of the frame, each of said rails comprising a cavity and two webs extending in the longitudinal direction of the rail, said two webs defining between them an opening also extending in the longitudinal direction f the rail, each of said corner-connectors comprising two plugs, each plug being inserted from an end inside the cavity of a rail, at least one of the webs comprising a retaining element projecting rearwardly behind the rear surface of said at least one web, each plug comprising in the vicinity of said retaining element a resilient tongue with a free end which extends outwardly from the cavity through said opening, said tongue having a width which is at the most equal to the width of said opening, at least one hook element extending outside said cavity behind said rear surface of said at least one web, and means for locking said hook element to said retaining element, said retaining element being arranged at an angle to said rear surface of said at least one web and being obtained by stamping out and rearwardly bending a portion of the web, said retaining element comprising a first engaging surface remote from a corner against which a second engaging surface on the tongue and the hook elements bears, and wherein said first and second engaging surfaces are arranged at an angle to the outer surfaces of the webs so that said tongue is urged towards said outer surfaces of the webs by the resulting wedging action.
