发明名称 Three-dimensional picture corners
摘要 Injection molded corners for framing pictures are designed to be attached to each corner of a picture and operate as both a hanger for a picture, as well as a means of providing a three-dimensional effect by holding the picture away from a supporting wall. The corners can be decorative so as to function totally as a frame, and a small injection molded pin is abuttable against the cardboard backing of a picture to effectively lock the corners in position.
