Abstract: A mid-wheel drive wheelchair can have various suspensions for the drive wheel such as a rigid connection to the wheelchair frame or a resilient connection thereto. The wheelchair has at least one anti-tip front wheel stabilizer, which is rigidly, i.e. non-resiliently, connected to the frame and accordingly the wheelchair frame moves up and down with the anti-tip wheel upon encountering a bump, hill, etc. The height of the anti-tip wheel above the travel surface is adjustable and accordingly the wheel can be set to a specific height.

Abstract: The power wheelchair includes an anti-tip assembly extending from the frame. The anti-tip assembly includes a plate secured to the frame via a dampening mechanism. A first arm extends from the plate and is mounted thereto for a limited amount of relative movement. A grounding engaging wheel disposed on a distal end of the arm is urged toward the ground surface by a biasing spring interposed between the arm and the plate. As the wheelchair begins to tip, anti-tip or resistive forces are generated initially by the biasing spring. This resisting force continues in a linear fashion until relative movement between the arm and the plate ceases. Thereafter, further resistive forces are provided by the dampener as movement of the plate toward the frame is resisted in a linear fashion by the dampener.

Abstract: A wheelchair includes a rigid upholstered seat removably mounted on a crossbrace-type chassis. The seat includes a generally square-shaped frame having a clevis assembly depending from each of the four corners of the frame. Each one of a first pair of the clevis assemblies disposed at diagonally opposed front and rear corners of the seat frame is formed with aligned generally pear-shaped openings. Each one of a second pair of the clevis assemblies disposed at the other diagonally opposed front and rear corners of the seat frame is formed with aligned generally horizontal elliptical-shaped openings. An inverted generally U-shaped mounting bracket formed with aligned openings is disposed on each end of each one of a pair of chassis sideframes. Each clevis assembly is engageable with a respective one of the U-shaped brackets so that the respective openings of the engaged brackets are aligned. A quick release pin is passed through each set of aligned openings to secure the seat to the chassis.

Abstract: A convertible wheelchair permits change over from an attended wheelchair arrangement to a self propelled wheelchair arrangement. The wheelchair accommodates both lateral and longitudinal dimensional changes. Further, the seat can pivot relative to the frame, as well as permitting a seat back to tilt relative to the seat portion. In the attended wheelchair arrangement, the rear wheels are simultaneously locked.

Abstract: An office space dividing system comprising office furniture components in combination with a plurality of structural rectangular frames having openings which may be left open or closed in varying degrees with a wide variety of fill options, which may be readily changed, to create the desired degree of privacy. The system combines the advantages of a full height office partition system with lockable doors, and an open plan panel system. An enlarged cornice accommodates both wiring and ambient lighting, with a cornice to ceiling space being left open or closed with a clerestory, as desired, without compromising the ability to install lighting fixtures and wiring. The rectangular frames have mitered stiles which, when assembled with other frames, and/or mitered fill pieces, create columns defining vertical wire ways which communicate with cornice wiring, work surface height wiring, and/or base wiring, as desired.

Abstract: An assembly for supporting and storing paper, reference materials and other like items on a space divider and furniture system off of work surfaces includes paired hanging vertically extending brackets having one or more horizontally projecting cantilevered arms. Each bracket includes an upper hook and alternative forms of a lower foot which maintains the brackets vertical and the arms horizontal. The hook and feet are removably secured to the ends of the brackets and the alternative feet are employed depending on the height at which the assembly is mounted on the space divider system. The brackets may be mounted anywhere along the space divider system. The arms in turn support with a snap fit several forms or sizes of molded plastic trays which interconnect the paired brackets. The arms are circular in section and the edges of the tray are provided with downwardly turned circular edges which snap over the arms. Projections partially closing such openings assist in retaining the trays on the arms.
