Rear wheel assemblies (B) are connected with the left and right side frame portions such that the rear wheels are connectable to the frame in any one of a plurality of positions and with an adjustable camber. A pair of front wheel assemblies (C) selectively interconnect front wheels with the frame with any one of a plurality of adjustable height, inward-outward, and forward-aft positions. An operator supporting seat (D) having a segmented center portion and an outer portion is selectively interconnected with the left and right side frame portions. A folding mechanism (E) enables the left and right side frame portions to be folded together for easier transportation and storage.

摘要： The sports wheelchair includes a one-piece, welded tubular frame assembly (A). A pair of rear wheels (30) are horizontally and adjustably positionable in a rear wheel mounting plate (34). The mounting plate has a plurality of slots (36, 38, 40) and a plurality of alternating ridges (44) and valleys (46) which mesh with like ridges (50) and valleys (52) on an axle receiving assembly (42). A pair of front wheels (80) are mounted with a front wheel mounting assembly (82) to be selectively positioned in any one of three vertical positions (FIGS. 6, 8, and 9). The front wheels are further mountable on the inside or the outside of a lower horizontal frame portion (10) and in any one of a plurality of positions fore and aft along the horizontal frame portion. The user is supported by a fabric seat (170) which is laced to upper horizontal frame portions (12) and to a back structure (150). The back structure is connected with the frame structure by a hinge (152) such that the back is selectively foldable for easier transportation. A foot supporting structure (180) is selectively positionable in any one of a plurality of positions. A roller (202) is positioned on the foot support to inhibit the chair from tipping forward. A shield (210) inhibits the fingers of the user or others from engaging spokes of the rear wheel and causing injury.

摘要： A stroller base (A) detachably receives a seat structure (B) therein. The base includes forward wheel assemblies (12), rearward wheel assemblies (14) for rollably supporting the base, and wheel lock structures (60) for selectively locking the rear wheels against rotation. An upper base frame portion (20) is collapsable to a folded position (FIG. 3) and raiseable to a seat structure receiving position (FIG. 2). The upper base frame portion includes a channel guide (30) having a transverse slot (38) therein. The detachable seat structure includes a seat frame (80) with a plurality of patient supporting pads (90, 92, 94, 96) adjustably mounted thereon. Handles (84) selectively enable an attendant to lift a rearward portion of the detachable seat structure. A transverse seat frame member (88) is selectively received in the channel guide slot as the seat structure is positioned thereon and selectively lifted out of the channel guide slot as the seat is lifted therefrom. The seat frame adjustably mounts a footrest structure (140) and a roller (130) at a forward, lower end thereof. In operation, the attendant pivots the detachable seat structure about the transverse seat frame member to raise the roller above a door sill of a motor vehicle. The stroller is moved forward with the forward wheel assemblies passing below the door sill and the roller passing above the door sill. The attendant lifts the detachable seat structure by the handles raising the transverse bar from the channel guide and pivoting the chair about the roller until it is positioned over the seat of the motor vehicle. Thereafter, the base is folded and disposed in the trunk of the motor vehicle.
摘要翻译： 婴儿车座（A）可拆卸地容纳座椅结构（B）。 底座包括前轮组件（12），用于可滚动地支撑底座的后轮组件（14）和用于选择性地锁定后轮以防旋转的轮锁结构（60）。 上部基座框架部分（20）可折叠到折叠位置（图3）并且可升高到座椅结构接收位置（图2）。 上基架部分包括其中具有横向狭槽（38）的通道引导件（30）。 可拆卸的座椅结构包括具有可调节地安装在其上的多个患者支撑垫（90,92,94,96）的座椅框架（80）。 手柄（84）选择性地使服务员能够抬起可拆卸座椅结构的后部。 当座椅结构位于其上时，横向座椅框架构件（88）被选择性地容纳在通道导槽中，并且当座椅被提升时，横向座椅框架构件88被选择性地容纳在通道导槽中。 座椅框架可调节地将搁脚板结构（140）和辊子（130）安装在其前端的下端。 在操作中，服务员围绕横向座椅框架构件枢转可拆卸的座椅结构，以将辊子升高到机动车辆的门槛上方。 婴儿车向前移动，前轮组件通过门槛下方，辊子通过门槛上方。 服务员通过手柄提升可拆卸的座椅结构，该把手从导槽引导件提升横向杆，并使座椅绕着滚轴转动，直到其位于机动车辆的座位上方。 此后，基座被折叠并设置在机动车辆的行李箱中。

摘要： A collar or body portion (40) has an inner surface (42) that defines a circular bore (44) therethrough. A cam surface (46) is recessed into the collar portion from the circular bore. The collar is disposed with a tubular member (22) extending through the circular bore with a spring biased detent (30) engaging the cam surface. A series of upper plateaus or segments (60) and lower plateaus or segments (62) hold the detent against the cam surface as the collar is rotated. A handle portion (64) facilitates manually rotating the collar to depress or release the spring biased detent.

摘要： A low profile wheelchair includes first and second frame portions that may be selectively spaced apart in an operative position and brought together in a stored position. Armrests, seat back, and footrests are each pivotally mounted to the frame portions so as to minimize the height and length of the wheelchair in a storage position.
