    摘要： A structural support assembly, more particularly incorporating a joint useful in the preparation of structural support assemblies such as ladders, scaffolds and trusses. The joint has a male member (42) with an open-ended hollow projection which defines an inner wall and an outer wall. The joint also has a wooden female member having a socket defined by a groove in the form of a closed loop having opposing walls. The projection of the male member is fitted in a clearance fit in the socket and is secured therein by a binding material which contacts the inner and outer walls of the projection and the opposing walls of the socket. The binding material also permeates the female member surrounding the socket. A process for the preparation of such structural supports is also described.

    摘要： The present invention discloses a device for use in carpentry, painting, and other construction. The device has two side members (12, 14) shaped generally as quadrilaterals with the first side member (12) being a mirror image of the second side member (14). A first surface (64) joins a first edge (16) of the first side member to a fifth edge (24) of the second side member. A second surface (66) joins a second edge (18) of the first side member to a sixth edge (26) of the second side member. The fourth edge (22) of the first side member and the eighth edge (30) of the second side member have teeth (76, 78, 80, 82) which engage a surface. The fourth edge and the eighth edge also have cut outs (86, 88) which assist in engaging a ladder. A handle (118) can be provided for easy carrying. A third surface (68) joins the first side member to the second side member.

    摘要： The invention provides a tripod assembly comprising a plurality of legs, a central support member, and a central post. Each of the legs is pivotably coupled to the central support member. The central support member surrounds the central post. A plurality of columns is disposed in a nested arrangement for relative axial movement in a telescopic fashion along an axis of the plurality of columns between a fully-extended position and a collapsed position. The columns are received in the central post when the columns are in the collapsed position. A first end of a connecting rod is coupled to one of the columns. A bracket assembly is coupled to a second end of the connecting rod and is configured to receive a rung of a ladder therein. A bracket member is coupled to an uppermost column and includes a channel configured to receive a second rung of the ladder therein.
