A clamping spring in the form of an arch of resilient wire is mounted on a base which is fixed on the back of one side of a picture frame. The arch is capable of pivotal displacement about an axis which is parallel to the edge of the corresponding side of the picture frame. The lateral arms of the arch extend transversely and terminate in elbowed extremities which are pivotally mounted in the base. Transverse cheeks of the base are located on each side of the arch and are each provided with a flange or groove for locking the corresponding lateral arm of the resilient arch in its position of downward engagement against the base. In this position, the free end of the arch projects inwardly of the frame and is applied against the rear face of the picture. A picture is finally fixed in position when a similar device has been mounted on each side of the frame.
A device for fixing a picture within a frame, said device comprising a base having a flat undersurface lying in a plane, a clamping spring mounted for pivotal movement on the base, said clamping spring having the shape of an arch of resilient wire having lateral arms which are resilient and which terminate in elbowed ends pivotally mounted on the base for swinging movement between an open position and a closed position, said base having recesses thereon which receive and releasably retain said arms only in said closed position of said spring, and cheek means on said base which define a portion of said recesses and which can be passed by said arms only by resilient deformation of said arms upon movement of said spring from said closed position toward said open position, said elbowed ends being disposed above said plane, said arms extending from said elbowed ends beyond said base and passing through said plane and terminating in a cross piece that interconnects said arms and is disposed below said plane.
In combination with a picture frame having an open channel at the rear end and a picture disposed in the frame with the edges of the picture in said open channel, a device comprising a base which is fixed against the back of the picture frame, a clamping spring mounted for pivotal movement on the base, said clamping spring having the shape of an arch of resilient wire having lateral arms which are resilient and which terminate in elbowed ends pivotally mounted on the base for swinging movement between an open position for emplacing or removing the picture in or from the frame, and a closed position in which the clamping spring bears against the back of the picture to hold the picture in the frame, said base having recesses thereon which receive and releasably retain said arms only in said closed position of said spring, and cheek means on said base which define a portion of said recesses and which can be passed by said arms only by resilient deformation of said arms upon movement of said spring from said closed position toward said open position.
