Abstract
The present invention comprises a corner fastener for securing a first and second frame member together to form a corner of a frame. The corner fastener, in one embodiment, includes a first leg member cooperatively connected to a second leg member. Proximal sections of the leg members have raised surfaces which act as a pivoting point when the corner lock is utilized. In addition, the leg members have distal sections which are deformable, during installation, to assist in the alignment and adjustment of the mitre angle.

A unitary corner fastener for use in securing first and second frame members with use of first and second fastening members together to form a corner of a frame, the frame members each having a mitered end and each of the frame members forming an opening and channel cavity at its mitred end, said channel cavities being a first channel cavity in said first frame member and a second channel cavity in said second frame member said channel cavities having first surfaces and second, opposite surfaces, said fastener comprising:
- (a) a first leg member having a first and second end, and a second leg member, having a first and second end, said first ends cooperatively connected to each other at an intersection;
- (b) said leg members in relation to the intersection each having proximal and distal sections;
- (c) said proximal sections each having a threaded aperture formed therein for receiving fastening members;
- and
- (d) said distal sections being offset relative to said proximal sections respectively, whereby when said fastener is inserted in the channel cavities, said distal section of the first leg member contacts the first surface of the first channel cavity and the distal section of the second leg section contacts the first surface of the second channel cavity, wherein said distal sections act as a fulcrum against the first surfaces when the fastening members are tightened through said apertures and brought closer to the frame members by rotation of said fastening members in said threaded apertures, thereby permitting alignment and adjustment of the mitres of the first and second frame members.
A unitary corner fastener for use in securing first and second frame members with use of first and second fastening members together to form a corner of a frame, the frame members each having a mitered end and each of the frame members forming an opening and channel cavity at its mitred end, said channel cavities being a first channel cavity in said first frame member and a second channel cavity is said second frame member, said channel cavities having first surfaces and second, opposite surfaces, said fastener comprising:
- (a) a first leg member having a first and second end, and a second leg member, having a first and second end, said first ends cooperatively connected to each other at an intersection;
- (b) said leg members in relation to the intersection each having proximal and distal sections;
- (c) said proximal sections each having an aperture formed therein through which the fastening members may pass;
- (d) said first leg member having an auxiliary section cooperatively connected to said distal section, said auxiliary section of said first leg having an a threaded aperture for receiving the first fastening member;
- (e) said second leg member having an auxiliary section cooperatively connected to said distal section, said auxiliary section of said second leg having a threaded aperture for receiving the second fastening member;
- and
- (f) said distal sections being offset relative to said proximal sections respectively, whereby when said fastener is inserted in the channel cavities, said distal section of the first leg member contacts the first surface of the first channel cavity and the distal section of the second leg section contacts the first surface of the second channel cavity, wherein said distal sections act as a fulcrum against the first surfaces when the fastening members are tightened through said threaded apertures and brought closer to the frame members by rotation of said fastening members in said threaded apertures, thereby permitting alignment and adjustment of the mitres of the first and second frame members.
A frame corner comprising:
- (a) a first frame member having a mitred end and forming an opening and channel and first channel cavity at its mitred end;
- (b) a second frame member having a mitred end and forming an opening and second channel cavity member at its mitred end;
- (c) both of said cavities having first surfaces and second, opposite surfaces;
- and
- (d) a corner fastener for cooperatively connecting said first frame member to said second frame member, said fastener comprising:
- (i) a first leg member having a first and second end, and a second leg member, having a first and second end, said first ends cooperatively connected to each other at an intersection;
- (ii) said leg members in relation to the intersection each having proximal and distal sections;
- (iii) said proximal sections each having a threaded aperture formed therein for receiving fastening members;
- and
- (iv) said distal sections being offset relative to said proximal sections respectively, whereby when said fastener is inserted in the channel cavities, said distal section of the first leg member contacts the first surface of the first channel cavity and the distal section of the second leg section contacts the first surface of the second channel cavity, wherein said distal sections act as a fulcrum against the first surfaces when the fastening members are tightened through said apertures and brought closer to the frame members by rotation of said fastening members in said threaded apertures, thereby permitting alignment and adjustment of the mitres of the first and second frame members.
A frame corner comprising:
- (a) a first frame member having a mitred end and forming an opening and channel and first channel cavity at its mitred end;
- (b) a second frame member having a mitred end and forming an opening and second channel cavity member at its mitred end;
- (c) both of said cavities having first surfaces and second, opposite surfaces;
- and
- (d) a corner fastener for cooperatively connecting said first frame member to said second frame member, said fastener comprising:
- (i) a first leg member having a first and second end, and a second leg member, having a first and second end, said first ends cooperatively connected to each other at an intersection;
- (ii) said leg members in relation to the intersection each having proximal and distal sections;
- (iii) said proximal sections each having an aperture formed therein through which the fastening members may pass;
- (iv) said first leg member having an auxiliary section cooperatively connected to said distal section, said auxiliary section of said first leg having an a threaded aperture for receiving the first fastening member;
- (v) said second leg member having an auxiliary section cooperatively connected to said distal section, said auxiliary section of said second leg having a threaded aperture for receiving the second fastening member;
- and
- (vi) said distal sections being offset relative to said proximal sections respectively, whereby when said fastener is inserted in the channel cavities, said distal section of the first leg member contacts the first surface of the first channel cavity and the distal section of the second leg section contacts the first surface of the second channel cavity, wherein said distal sections act as a fulcrum against the first surfaces when the fastening members are tightened through said threaded apertures and brought closer to the frame members by rotation of said fastening members in said threaded apertures, thereby permitting alignment and adjustment of the mitres of the first and second frame members.
