The present invention relates to a segmented, combination level and square that has a rotating joint. In a preferred embodiment, this hand tool provides the user with many optional tools in one. The tool can be configured as a level, a T-square, a framing square, a T-bevel, or a pocket square. In a preferred embodiment, this multi-segmented combination tool also provides the user with a convenient way not only to configure a level, in one inch increments, to any length from several inches to at least ten feet in length, but also to create more than one tool at a time such as a T-level and a framing square. In other preferred embodiments, the user is provided with optional features that enable them to carry on-site a single tool that can perform all tasks needed to do general construction layout such as roof framing.

A detachable rotating joint means comprises a male coupling member connected to a female coupling member by a combination disengaging and angle setting means disposed about the female coupling member, said rotating joint means being able to establish a predetermined number of angles between the male coupling member and the female coupling member, wherein: a) the female coupling member has a top, a bottom, a first lateral exterior surface, a second lateral exterior surface, a distal end, and a proximal end, wherein; i) the proximal end is dimensioned and configured so as to form a circular arc of up to about 180 degrees extending from the top to the bottom; ii) a receiving slot is disposed about the proximal end, said receiving slot extending vertically from the top to the bottom of the female coupling member, thereby forming a first lateral interior surface, a second lateral interior surface, and a distal interior surface, at least a portion of said distal interior surface dimensioned and configured as a circular arc that can function as a bearing race; iii) a shaft opening is disposed horizontally from the first lateral exterior surface through the first interior lateral surface and into the second lateral interior surface, the axis of the shaft opening being within the circle formed by the circular arc on the proximal end; and iv) an interior recess is disposed on the second lateral interior surface, said interior recess encompassing the shaft opening; b) the combination disengaging and angle setting means disposed about the female coupling member comprises: i) a shaft having a distal end and a proximal end, said shaft being disposed in the shaft opening and being dimensioned and configured so as to move laterally within the shaft opening and to be within the shaft opening in the first lateral exterior surface and the second lateral interior surface; ii) a spring means disposed about the shaft so as to apply a laterally outward force on the shaft away from the second lateral interior surface and towards the first lateral exterior surface; and iii) a circular disc having a plurality of splines disposed about the circumference of the disc in a pattern corresponding to the predetermined angles, said splined disc being connected to the shaft so as to be concentric with the circular arc on the proximal end of the female coupling member, being disposed within the receiving slot when no force is applied inwardly to the shaft, and being dimensioned and configured such that the splined disc is larger than the shaft opening and is able to be received within the interior recess; wherein when an inward force is applied to the shaft, the spring is compressed, and the splined disc is received into the interior recess, only a portion of the shaft remaining in the receiving slot; and c) the male coupling member has a top, a bottom, a first lateral exterior surface, a second lateral exterior surface, a distal end, and a proximal end, wherein the proximal end of the male coupling member is in a mating relationship with the receiving slot and the splined disc of the female coupling member, said proximal end comprising: i) a circular member, a portion of which forms a bearing surface, said circular member being dimensioned and configured so as to be able to be received within the receiving slot of the female coupling member such that the bearing surface is adjacent to the bearing race on the distal interior surface of the receiving slot when an inward force is applied to the shaft and the splined disc is received within the interior recess; ii) a center opening disposed concentrically with the circumference of the circular member, said opening being dimensioned and configured with splines so as to mate with the splined disc in the female coupling member when the proximal end of the male coupling member is in the mating relationship with the female coupling member; and iii) a shaft slot extending from the circumference of the circular member to the center opening, said shaft slot being dimensioned and configured to be larger than the shaft in the female coupling member so as to allow the circular member to be received within the receiving slot whereby the center opening is concentric with the splined disc when the inward force is applied to the shaft.
