发明名称 Non-removable picture frame hanger and hanging method
摘要 A non-removable hanger for a picture frame comprises a pair of flat hanger members having openings at each end, threaded fasteners for pivotably attaching lower ends of the hanger members to opposite vertical sides of the frames and threaded fasteners for attaching upper ends of the hanger members to the wall. The hanger members are attached to the wall after being attached to the back of the frame by rotating or pivoting the picture frame against the wall so that the ends of the hanger members are alternately exposed. The exposed ends are screwed into the wall. A spring lock engages the hanger members and prevents them from pivoting once the frame is mounted and positioned in its proper vertical position.
