A carpenter tool includes a triangular body having a hypotenuse edge opposite a right corner, a first edge extending between the right corner and the hypotenuse edge, and a second edge extending between the right corner and the hypotenuse edge opposite the first edge. A fence is pivoted to the first edge for movement between first and second positions. In the first position, the fence is normal to the triangular body. In the second position, the fence is coplanar to the triangular body.

Multi-axis alignment tools are described. The tools are usable to arrange workpieces across a variety of different axes and orientations and to ensure consistent and durable alignment of various workpieces while providing access for working thereon, which is not possible using conventional tools.

A stepwise and stepless adjustable square, including: a stock; a blade; a first alignment structure; a second alignment structure; a spring device; and a knob movable between a first position and a second position, wherein in the first position the first and second alignment structures at certain angles between the stock and the blade align and engage such that a force of the spring device is reduced compared to the force at angles where the first and second alignment structures do not align for stepwise adjustment, and wherein in the second position the second alignment structure is moved axially away from the first alignment structure, whereby the first and second alignment structures are separated from each other, and a first surface associated with the blade is brought into frictional engagement with a second surface associated with the stock for stepless adjustment.

A projection system includes: a projection device that includes a laser scanner and projects one or more drawings individually onto work spots in a work site; and an adjustment unit configured to adjust at least one of (i) a quantity of the one or more drawings to be simultaneously projected by the projection device or (ii) a setting parameter regarding a mode of projection performed by the projection device.

A projection method, which is executed by a projection device, for projecting drawing data for a building onto a projection plane of the building under construction includes: measuring a distance from each of three or more points which are not aligned in a straight line and are on either of two non-parallel straight lines on the projection plane to the projection device using a distance meter included in the projection device; and projecting the drawing data onto a projection position on the projection plane which is determined based on the distance measured and the angle of the distance meter at the time at which the distance is measured.

A horizontal portion of a frame, as a door header, of a predetermined length for installation between two adjacent studs of a stud wall spaced from one another. An installation tool, releasably mounted on a respective stud via a magnetic attachment, supports a respective end of the horizontal portion adjacent the metallic stud during attachment of the horizontal portion to the stud. A kit formed of at least one horizontal portion and at least one installation tool is also provided.

A scribe for measuring and marking pipe protrusions on a cabinet panel may include a foot designed to be positioned against a ground surface, the foot sized to accommodate placement of an end of an elongate rail therein; a housing sized to encircle a portion of the elongate rail; a pair of adjustment arms pivotably attached to the housing; a pipe measuring component slidably attached to each of the pair of adjustment arms; and a pipe return alignment protrusion extending from an outer surface of the housing, the pipe return alignment protrusion sized to accommodate an end of a pipe return line therein.

A system and method are provided for designing/creating, preparing, and installing a natural stone tiled surface at a site that provides a perception of randomness to the observer while actually following a predefined pattern that facilitates simple installation by unskilled trades and allows for the advanced preparation of the stone tiles used. Advanced preparation of the stone tiles allows the offloading of at least some cutting, preparation and installation steps normally required onsite, to an offsite location. The system relies on the tessellation or tiling of a specific outline of an irregular concave polygon, that itself includes an internal set of irregular convex polygon shapes. The tessellation of an outline that includes such a set of shapes provides an optical effect that makes it difficult for an observer to recognize the repeating nature of the stones within the patterned outline. The system can include one or more orthogonal reference lines to align with reference edges.

A bendable tube having pre-marked horizontal and vertical alignment guides which allow a user to form successive bends of the tube in the same plane. The horizontal and vertical alignment guides are coplanar with a horizontal plane and a vertical plane which axially bisect the tube and are perpendicular to each other. The horizontal and vertical alignment guides allow the tube to be precisely aligned within a bending apparatus, ensuring that the horizontal alignment guides remain coplanar with the horizontal plane when performing a horizontal bend, and that the vertical alignment guides remain coplanar with the vertical plane when performing a vertical bend.
