Abstract
Abstract A knockdown picture frame having two perpendicularly arranged pair of opposed frame members, each member having spaced end portions provided with a hole passing therethrough from an opening provided in an outer wall surface to an opening provided in an end wall surface and arranged to mate with a similar hole in the end portion of an abutting frame member. The frame members are connected together by a longitudinally extending, flexible member passing through the holes and having spaced ends fastened together by a loop formed in one end and a disc provided with a pair of holes. The other of the ends of the flexible member is passed through the holes in the disc, the loop in the one end of the flexible member, and between itself and the disc.

Claim 3
Dependent Claim
60 words
A structure as defined in claim 1, wherein each of said end portions is provided with groove means in a rear outer wall surface arranged adjacent said outer wall surface for guiding said flexible member from the opening provided in said outer wall surface to an inner wall surface adjacent said rear outer wall surface for tightening said flexible member.
Claim 4
Dependent Claim
151 words
A knockdown picture frame, comprising, in combination: a. a plurality of frame members, each frame member having spaced end portions disposed in abutting engagement, each end portion provided with a hole passing therethrough from an opening provided in an outer wall surface to an opening provided in an end wall surface and arranged to mate with a similar hole in the end portion of an abutting frame member; and b. means passing through the holes for connecting the frame members together, and including a longitudinally extending, flexible member with spaced ends, and means for selectively fastening together said ends, each of said end portions being provided with groove means in a rear outer wall surface arranged adjacent said outer wall surface for guiding said flexible member from the opening provided in said outer wall surface to an inner wall surface adjacent said rear outer wall surface for tightening said flexible member.
Claim 5
Dependent Claim
151 words
A knockdown picture frame, comprising, in combination: a. a plurality of frame members, each frame member having spaced end portions disposed in abutting engagement, each end portion provided with a hole passing therethrough from an opening provided in an outer wall surface to an opening provided in an end wall surface and arranged to mate with a similar hole in the end portion of an abutting frame member; and b. means passing through the holes for connecting the frame members together, and including a longitudinally extending, flexible member with spaced ends, and means for selectively fastening together said ends, each of said end portions being provided with groove means in a rear outer wall surface arranged adjacent said outer wall surface for guiding said flexible member from the opening provided in said outer wall surface to an inner wall surface adjacent said rear outer wall surface for tightening said flexible member.
Claim 6
Dependent Claim
34 words
A structure as defined in claim 3 wherein said frame members are arranged in perpendicular relation with the end wall surfaces being inclined to form a mitered joint at the corners of the frame.
Claim 7
Dependent Claim
