Abstract
A miter saw assembly is presented as a power tool, the miter saw assembly includes a base; a fixture supported on said base; a proximal pair of arms, hinged with four hinges to said fixture at a first hinge point; a gear box plate, hinged with four hinges to said proximal pair of arms at a second hinge point; a distal pair of arms, hinged with four hinges to said gear box at a first end, and a second end hinged with four hinges to said distal pair of arms; a gearing assembly hinged to said gear box plate, with a first gear attached to a first one of said proximal pair of arms and a second gear attached to a first one of said distal pair of arms, and a rotary saw, mounted to said second end of said distal pair of arms.
Claims13
A miter saw assembly, comprising:
- (a) a base;
- (b) a fixture supported on said base;
- (c) a proximal pair of arms, having a first length, and hinged to said fixture at a pair of first hinges, such that said proximal pair of arms can swing through a movement plane and having a second pair of hinges opposed to said first pair of hinges;
- (d) a gear box plate hinged in said first dimension to said proximal pair of arms at said second hinge points, and wherein said proximal pair of arms are shaped, said first pair of hinges are positioned on said fixture, and said second hinges are positioned on said gear box plate, such that said gear box plate does not change orientation as said gear box plate is moved about said fixture;
- (e) a distal pair of arms, having a second length, and shaped and hinged to said gear box plate at a first end, and having a second end, opposed to said first end;
- (f) a rotary saw sub-assembly, mounted to said second end of said distal pair of arms;
- (g) a gearing assembly hinged to said gear box plate, but having a first gear rigidly attached to a first one of said proximal pair of arms and a second gear, engaged to said first gear, and rigidly attached to a first one of said distal pair of arms, so that said rotary saw sub-assembly is permitted to move in a first dimension of said movement plane, but remains stationary in a second dimension, orthogonal to said first dimension, as the rotary saw sub-assembly moves through said first dimension.
