Abstract

A fixture for holding workpieces at predetermined angles while they are being interconnected includes a pair of legs and a hypotenuse forming a right triangle, whose three vertices are truncated to enable the fixture to function as a jig, as a template, or as a bending tool. Workpieces may easily be attached to the fixture, obviating the need for special clamps.

Claims

1. A fixture comprising

a pair of mutually perpendicular legs,

a bridge interconnecting said legs, said bridge extending obliquely to each of said legs,

a pair of end portions, one on each of said legs, each end portion extending obliquely to its respective leg, and

a hypotenuse member extending between said end portions, the hypotenuse member being oblique to each of said legs,

said legs, bridge, end portions and hypotenuse member defining a polygon lying in a plane, each of said legs, bridge, end portions and hypotenuse member being disposed with its width extending perpendicular to said plane.

2. The invention of claim 1, further comprising a first gusset connected between the bridge and each of said legs.

3. The invention of claim 2, wherein said first gusset is attached at the middle of the width of the members to which it is attached.

4. The invention of claim 2, further comprising second and third gussets, each connected between one of said legs, a respective end portion, and said hypotenuse member.

5. The invention of claim 4, wherein each of said second and third gussets is attached at the middle of the width of the members to which it is attached.

6. The invention of claim 1, wherein said legs and said hypotenuse member each have plural through holes by which workpieces may be attached to the fixture.
