摘要： 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. The pear-shaped openings allow vertical articulation of the chassis relative to the seat in certain instances when a bump, depression or other irregularity on a travel surface is encountered by usually one of the wheels of the wheelchair. This articulation enables the wheelchair to insulate its occupant from shocks caused by such irregularities, and also maintains all wheels of the wheelchair in continuous contact with the travel surface to preserve occupant steering control and stability of the wheelchair.
摘要翻译： 轮椅包括可拆卸地安装在横梁式底盘上的刚性软垫座椅。 该座椅包括大致正方形的框架，该框架具有从框架的四个角中的每个角落悬挂的U形夹组件。 设置在座椅框架的对角相对的前角和后角处的第一对U形夹组件中的每一个形成有对准的大致梨形的开口。 设置在座椅框架的另一个对角相对的前角和后角处的第二对U形夹组件中的每一个形成有对准的大致水平的椭圆形开口。 形成有对准的开口的倒置的大致U形的安装支架设置在一对底盘侧框架中的每一个的每个端部上。 每个U形夹组件可与相应的一个U形支架接合，使得所接合的支架的相应开口对准。 快速释放销穿过每组对齐的开口，将座椅固定到底盘上。 在某些情况下，通常轮椅上的轮子之一遇到行程表面上的凸起，凹陷或其他不规则性时，梨形开口允许底架相对于座椅垂直铰接。 这种关节使得轮椅能够使其乘客与由此类不规则引起的冲击隔离，并且还使轮椅的所有轮子与旅行表面持续接触，以保持轮椅的乘员转向控制和稳定性。

摘要： 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.

摘要： 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.

摘要： 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. The trays are molded with a grid of slots and holes to receive and support snap-in zig-zag wire forms which may be used as tray back stops or to subdivide the trays to handle a variety of paper sizes or other items.
摘要翻译： 用于在工作表面上的空间分隔件和家具系统上支撑和存储纸，参考材料和其它类似物品的组件包括具有一个或多个水平突出的悬臂的成对垂直垂直延伸的支架。 每个支架包括上钩和下脚的替代形式，其保持支架垂直并且手臂水平。 钩和脚可移除地固定到支架的端部，并且根据组件安装在空间分配器系统上的高度采用替代脚。 支架可以安装在空间分配器系统的任何地方。 臂依次以卡合的方式支撑几个形式或尺寸的模制塑料托盘，其互连成对的托架。 臂部分是圆形的，并且托盘的边缘设置有向下转动的圆形边缘，其卡在臂上。 部分关闭这种开口的突出部有助于将托盘保持在臂上。 托盘被模制成具有狭槽和孔的格子，以接收和支撑嵌入式之字形线形式，其可用作托盘后挡块或细分托盘以处理各种纸张尺寸或其它物品。

摘要： 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.

摘要： 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.
