Three-axis ninety-degree triangular brace

Abstract

An open triangle made of rigid material planes each joined ninety degrees to one another and of sufficient thickness, rigidity, precision and construction for the triangle as a whole to serve as a brace for clamping, aligning, and joining workpieces, especially three workpieces at ninety degrees to one another; the opening of the triangular brace serving as a space for the operation of joining the workpieces, especially joining by means of high-heat welding but also by other means of joining, like drilling and fastening with bolts; the triangular brace being constructed of one piece, or a plurality of pieces in which one plane or all planes of the said brace are removable and re-attachable, or rotatable in and out of position, by means of screws, bolts, pins, interlocking tongue-and-groove, magnets, axle for rotation, or other secure means.

Claims

1. An open triangle made of rigid material planes each joined ninety degrees to one another and of sufficient thickness, rigidity, precision and construction for the triangle as a whole to serve as a brace for clamping, aligning, and joining workpieces, especially three workpieces at ninety degrees to one another; the opening of the triangular brace serving as a space for the operation of joining the workpieces, especially joining by means of high-heat welding but also by other means of joining, like drilling and fastening with bolts; the triangular brace being constructed of one piece, or a plurality of pieces in which one plane or all planes of the said brace are removable and re-attachable, or rotatable in and out of position, by means of screws, bolts, pins, interlocking tongue-and-groove, magnets, axle for rotation, or other secure means.

Description

DRAWINGS

[0005] In the following illustrations (FIGS. 1 through 4) the dotted lines represent workpieces to be joined in the aperture of the triangular brace. Clamps, such as c-clamps and vise-grips, and/or magnets, securing the workpieces to the triangular brace are not shown.

DETAILED DESCRIPTION OF THE INVENTION

[0006] An open triangle made of rigid material planes each joined ninety degrees to one another and of sufficient thickness, rigidity, precision and construction for the triangle as a whole to serve as a brace for clamping, aligning, and joining three pieces of material (workpieces), especially at ninety degrees to one another; the opening, or aperture, of the triangular brace serving as a space for the operation of joining said workpieces, especially joining by means of high-heat welding but also by other means of joining, like drilling and fastening with bolts; the triangular brace being of one piece (FIG. 1, 1a), or a plurality of parts in which one plane or all planes (FIG. 2, part 2b and FIG. 3, part 3a) of the triangular brace is (or are) removable and re-attachable, or rotatable in and out of position, by means of screws, bolts, pins, interlocking tongue-and-groove, magnets, axle for rotation, or other means (FIG. 2, parts 2c, and FIG. 3 parts 3b). For some cases of high-heat welding the inner faces of the triangular brace may possess ribs or insulators to prevent heat from dissipating to the material of the triangular brace. The planes of the triangular brace need not be straight “bars” and may be arcs, “L” shapes, etc. (FIG. 4), though such forms will not lay as flat for storage, stacking, and portability. For magnetic steel workpieces, an alternative to clamping the triangular brace to the workpieces will be to fix magnets into the triangular brace, one means being to sandwich bar magnets between faces of the triangular brace.

Novelty:

[0007] Like data-compression in computer systems, simplicity and resource-savings are important. The real novelties of my invention are its simple design, ease of manufacture, relatively light weight, portability, space-savings (stackable), affordability, and usefulness—ability to utilize a plurality of triangular brace units in several places to hold an entire workpiece together in alignment for joining.
