Bending tool
First Claim
1. A bending tool for bending a sheet material into a section, comprising a first bending member having a first bending projection formed with a bending edge of a substantially right angle and a first groove having a predetermined depth and an adjustable width and disposed in juxtaposition with said first bending projection, and a second bending member having a second bending projection formed with a bending edge of a substantially right angle and a second groove having a predetermined depth and an adjustable width and disposed in juxtaposition with said second bending projection, wherein said first and second bending members are disposed to be movable in opposition to each other in such a manner that a perpendicular bisector extending through the apex of the bending edge of said first bending projection passes substantially a center of said second groove, while a perpendicular bisector extending through the apex of the bending edge of said second bending projection passes substantially a center of said first groove.

Abstract
A tool for bending a sheet material into a L-like or Z-like section. A pair of bending members each having a bending edge and a rectangular cavity formed in juxtaposition are disposed movably toward and away from each other so that the bending edge of one of the bending members is movable into the cavity of the other bending member and vice versa. The cavity is of such a cross section that a major surface of the sheet material being bent is left free from the inner wall of the cavity.
