Adjustable picture frame
First Claim
1. An adjustable picture frame comprising a plurality of inner and outer frame members which are telescopically displaceable with respect to each other, each frame member having a front wall, two opposed sidewalls and a back wall, said picture frame further having an arresting stud with rounded cam surfaces mounted within each inner frame member so as to project through an opening formed in one side wall thereof, a spring member urging said arresting stud to bear against the adjacent side wall of the associated outer frame member, and at least two longitudinally spaced openings formed in said adjacent side wall for receiving said arresting stud to thereby releasably hold the inner and outer frame members in a predetermined relative position;
- a blocking stud mounted within each inner frame member so as to project through an opening formed in the side wall thereof opposite to said first side wall, said blocking stud having a rounded cam surface facing the outer end of said inner frame member, and a blocking surface extending substantially perpendicular to the longitudinal direction of the frame members, and located oppositely to said rounded cam surface, a spring means urging said blocking stud to bear against said adjacent side wall of the associated outer frame member, and an opening formed in said adjacent side wall near to the outer end of said outer frame member for receiving said blocking stud, thereby preventing further outward movement of said inner frame member with respect to said outer frame member while allowing relative movements of the frame members in the opposite direction.

Abstract
An adjustable picture frame comprising a plurality of inner and outer frame members telescopically displaceable with respect to each other. Each frame member has a front wall, two opposed sidewalls and a back wall. The picture frame has an arresting stud with rounded cam surfaces mounted within each inner frame member so as to project through an opening formed in one side wall thereof and a spring member urges the arresting stud to bear against the adjacent side wall of the associated outer frame member. At least two longitudinally spaced openings are formed in the adjacent side wall for receiving the arresting stud to thereby releasably hold the inner and outer frame members in a predetermined relative position. A blocking stud is mounted within each inner frame member so as to project through an opening formed in the side wall thereof opposite to said first side wall. The blocking stud has a rounded cam surface facing the outer end of the inner frame member, and a blocking surface extending substantially perpendicular to the longitudinal direction of the frame members and located oppositely to said rounded cam surface. A spring means urges the blocking stud to bear against the adjacent side wall of the associated outer frame member. An opening formed in the adjacent side wall near to the outer end of the outer frame member receives the blocking stud to prevent further outward movement of the inner frame member with respect to the frame member, while allowing relative movements of the frame members in the opposite direction.
