Abstract
Abstract A do-it-yourself picture frame includes a plurality of edge members, each having a circular or slot-like aperture proximate each end thereof, joined by a plurality of corner members. Each corner member includes first and second perpendicular channels for receiving the ends of adjacent edge members. Each channel is provided with a stop plate against which an end of an edge member may abut and an internally threaded projection which extends into an aperture in an edge member. A screw threadably engages the projection to secure the edge member in its channel.

Total Claims: 15
Claim 1
Independent Claim
106 words
A picture frame comprising: A. a plurality of edge members each having an aperture proximate each end thereof: B. a plurality of corner members for coupling said plurality of edge members together to form said frame, each of said corner members comprising: 1. first and second channels perpendicular to each other for receiving therein ends of adjacent edge members; and 2. an internally threaded projection within each of said channels for passing through said apertures to secure said adjacent edge members to one of said corner members; and C. screw means for threadably engaging said internally threaded projection from a second direction opposite said first direction.
Claim 2
Dependent Claim
106 words
A picture frame comprising: A. a plurality of edge members each having an aperture proximate each end thereof: B. a plurality of corner members for coupling said plurality of edge members together to form said frame, each of said corner members comprising: 1. first and second channels perpendicular to each other for receiving therein ends of adjacent edge members; and 2. an internally threaded projection within each of said channels for passing through said apertures to secure said adjacent edge members to one of said corner members; and C. screw means for threadably engaging said internally threaded projection from a second direction opposite said first direction.
Claim 3
Dependent Claim
33 words
A picture frame according to claim 1 wherein each channel is terminated by a stop plate having a step therein such that said stop plate has an upper edge and a lower edge.
Claim 4
Dependent Claim
30 words
A picture frame according to claim 2 wherein each corner member comprises an inner edge and an outer edge which form first and second sidewalls of each of said channels.
