Folding carpenter's square, bevel, and sliding bevel

摘要

A combination carpenter square and bevel/sliding bevel having three triangle-shaped adjoining legs, with an articulating joint between the hypotenuse leg and each adjoining leg. The other two non-hypotenuse legs are capable of forming a substantially 90 degree angle between the two non-hypotenuse legs to function as a carpenter's square. At least one of the articulating joints at the hypotenuse leg is capable of tightening and loosening. The hypotenuse leg also consists of a slot positioned longitudinally of the hypotenuse leg. The tightening and loosening articulated joint joins the hypotenuse leg with an adjacent non-hypotenuse leg through the slot, which allows the adjacent non-hypotenuse leg movement about the joint relative to the hypotenuse leg to function as a bevel. The articulated joints allow the combination square and bevel/sliding bevel to be folded into a compact shape.
