Abstract
A corner key for securing channel members to form a frame, such as a gate frame which consists of two substantially identical mating members. Each of the members is in the form of two identical sections joined substantially at right angle to each other. There is at least one transverse groove on the face of each section which will mate with the other member so that when the mating faces of the identical members of the key are placed face to face apertures are provided in the corner key. These apertures are adapted to receive fastening means which tend to wedge the members apart thus creating a tighter fit in the channel member.
Claims3
A corner key for use in securing channel members together to form a frame, said corner key comprising a pair of mating substantially identical members, each said member having two sections joined at their ends to form an L-shaped corner key, at least one transverse groove in a mating face of each of the sections adjacent an end thereof so that when mating identical members are placed face to face said grooves provide threaded transverse apertures which are less than cylindrical, whereby cylindrical threaded bolts inserted in said apertures cause said members to be urged apart, one said transverse groove in one section of said member having a thread which is one-half turn ahead of the thread in said groove of said other section of said member so that mating threaded grooves will provide a threaded aperture to receive said bolt.
