Abstract: A carriage assembly and a base therefor, are disclosed. The base comprises a pair of elongated feet, a bi-ended stiffening member and mounting means. The mounting means are located on each of the feet for mounting a portion of a leg of an upstanding, bi-legged frame member. Each foot defines a longitudinal axis between respective ends thereof. Each end of the stiffening member is carried by a respective foot to keep the longitudinal axis of one foot in parallel relation with the longitudinal axis of the other foot thereby providing the base with structural rigidity. Each foot includes respectively a wheel at one end thereof and a pad at an opposite end thereof. As to an individual foot, the wheel is aligned to provide the foot with mobility in the direction of its longitudinal axis, and each such mounting means is superimposed intermediate a certain pair of load-bearing regions of the foot thereby providing the base with stability.

Abstract: An integrally formed joining device is disclosed. The joining device comprises a first and a second backing member portion and a bracing member portion interposed therebetween. The bracing member portion is integrally formed respectively with each of the first and the second backing member portions. The bracing member portion defines a continuous and curved edge for the joining device.

Abstract: A dual purpose bracket is provided for cooperating with a corner post structure to join adjacent sides of a piece of furniture and to mount a caster-receiving socket. This dual purpose bracket comprises a single strip of substantially flat material formed to define a pair of substantially symmetrical joining portions and a socket-receiving portion intermediate and continuous with these joining portions. Each of the joining portions includes a portion locatable substantially coplanar with one of the adjacent sides to be joined and attachable to one adjacent side and to the corner post. The socket-receiving portion comprises a curved surface projecting inwardly with respect to an imaginary corner defined by the adjacent sides, the curvature thereof being similar to the curvature of at least a portion of the caster-receiving socket to receive the caster-receiving socket inwardly of the corner post.
