Abstract: The invention is of a modular chair assembly system which includes a single chair frame design and, to be used in the alternative, a plurality of sled back chair support members and a plurality of clerical style seat support members and clerical style back support members. Chairs of either sled back or clerical style can be assembled with the use of the single frame style.

Abstract: The desk has a top member and two pairs of legs with each pair of legs including a front leg and a rear leg with the front leg effectively having a height greater than that of the rear leg such that the front edge of the top member is higher than the rear edge of the top member. The front edge of the top member has a length greater than the length of the rear edge of the top member such that the top member is generally trapezoidal in shape. The two pairs of legs are secured to the lower side of the top member near its two side edges respectively such that the front legs are located at the front of the desk and the rear legs are located at the rear of the desk and the distance between the two front legs is greater than the distance between the two rear legs. Two of the desks may be nested together by locating the rear legs and the rear portion of the top member of one desk between the front legs and under the front portion of the top member respectively of the other desk.

Abstract: What is disclosed is a collapsible wire rack characterized by two substantially identical and planar ends for receiving a bottom; a pair of horizontal wire members having at both ends a bent hook eye structure for pivotally receiving respective side end wire members to allow collapsibility; the horizontal wire members being affixed to the rectangularly shaped centerpiece; two substantially identical planar sides; more elongate member defining a more supporting top; four sets arranged one at each end of each side of three shortened vertical wire members, two of each set being bent in a U-shaped configuration for carrying a nut means for screwingly, removably receiving a threaded shaft of a caster; and one of each set having a bent hook structure adjacent its lower end and disposed substantially level with the bent hook structure of the vertical wire member of each end for receiving the bottom; a plurality of substantially horizontal wire members connected with the elongate rectangularly shaped centerpiece and

Abstract: A plastic chair which is assembled from only several unitary pieces, some of which can be identical to each other. The chair seat takes the form of a unitary seat-back shell of molded plastic material. The base structure takes the form of two molded plastic pieces having male and female connecting portions to permit joining the pieces of the base merely by fitting them together. Connecting flanges on the seat-back shell permit securing the seat to the connecting portion of the base. The base pieces are secured together by ultrasonic welding and the seat is ultrasonically welded to the base. The method of making the chair includes molding the several pieces from a colorant containing plastic and securing the pieces together. Each leg includes a plurality of webs to permit cutting the legs so a chair of a desired height is obtained while simultaneously obtaining floor engaging glides. Strengthening ribs and rigidity to the chair, and the plastic can include glass fiber reinforcing for additional strength.

Abstract: A chair seat and supporting base for the seat, each of which can be of unitary construction. The base is formed from a plastic material and has legs, the side walls of which merge smoothly into depending peripheral skirts of an upper supporting portion of the base. The legs have a plurality of vertical strengthening webs which are unexposed when the base is in its normal upright position. In addition, there is a grid-work of longitudinal and transverse walls each of which is vertical and which provide additional beam strength and rigidity to the base. Several arrangements are provided for securing a seat-back shell to different embodiments of the base. A unique glide arrangement is also disclosed which permits severing the legs at a desired height to provide chairs of different heights while providing a flat floor engaging glide that is secured against removal, for example, by ultrasonically bonding the glide to the foot of the chair leg.
