ABSTRACT:
A turn button for a picture frame back includes an elongated metal body portion. A pivot boss is provided on the bottom side surface adjacent to a first end. The pivot boss includes an upstanding cylindrical wall with a free upper edge and an aperture therethrough for rotatably securing the turn button to a first portion of a picture frame. The free upper edge of the cylindrical wall serves as a cutting edge and is capable of piercing through a picture frame back. A smooth glide pad is also provided and has a substantially smooth outwardly facing surface for engaging a second portion of the picture frame in order to retain a second portion in a predetermined position relative to the first portion and to avoid excess damage to the picture frame back. A turning knob is also provided to facilitate hand manipulation of the turn button by the user. The use of the cylindrical wall as a cutting edge avoids the use rivets for attachment and the pre-punching of holes into the picture frame back prior to installation of the turn button.
