    Abstract: A wheelchair wheel lock system is provided that can be adapted for either pull-to-lock or push-to-lock operation. The wheel lock system includes a function plate with first and second pivot holes. An operating lever is attached to the function plate, and rotation of the lever causes rotation of the function plate and thereby moves a contact arm into engagement with the wheel of the wheelchair to lock the wheel against movement. The operation of the wheel lock system is changed between push-to-lock and pull-to-lock by adapting the function plate to rotate about either the first pivot hole or the second pivot hole. The operating lever can be attached to the function plate in a variety of orientations, providing added flexibility in the operation of the wheel lock system.

    Abstract translation: 提供了一种轮椅锁定系统，可以进行拉锁或按锁操作。 轮锁系统包括具有第一和第二枢转孔的功能板。 操作杆附接到功能板上，并且杆的旋转引起功能板的旋转，从而使接触臂移动到与轮椅的轮子接合以锁定车轮以防止运动。 通过使功能板相对于第一枢轴孔或第二枢轴孔旋转来改变锁定系统的操作在推动锁定和拉动锁定之间。 操作杆可以以各种方向安装到功能板上，为车轮锁系统的操作提供了额外的灵活性。

    Abstract: A tiltable seating frame (10) for selectively positioning seating in a wheelchair, in which a seat platform (12) has opposing sides (18) that each extend to an arcuate distal edge (20) and each side defines an arcuate slot (22) parallel to the distal edge. A base (14) has opposing sides (70) that receive pairs of front and rear rollers (72, 74) on which the distal edges (20) travel. Each side (70) also receives a guide roller (76) attached intermediate and vertically spaced relative to the front and rear rollers (72, 74). The guide rollers (76) extend through the respective arcuate slot (22) of the seat platform (12), to guide the movement of the seat platform (12) relative to the base (14).

    Abstract: A caster block for receiving a caster wheel for a wheelchair, in which a housing defines a central bore and spaced-apart bores for bolts to connect the caster block to the wheel chair. A resilient core in the central bore defines recesses in opposing distal ends for bearing races. A shaft of a caster wheel extends through the core. A wheel lock for restraining a wheel on the wheel chair has a bottom plate with a flange extending to one side to define a recess between an accurate cavity and a mounting block. An edge of a top plate matingly engages the cavity. The top and bottom plate sandwich a frame member. A handle with a lock arm pivotally connects to the bottom plate. A pin extends from the lock arm, and engages a wheel upon movement of the handle, to secure the wheel from rotation.

    Abstract: A wheelchair having a chassis formed of flat plate which is folded to define a lower chassis, a chassis back, and an upper chassis. The lower and the upper chassis each have a pair of elongated substantially parallel arms that extend from respective land portions of the chassis. The arms define openings in distal portions for receiving caster wheels. Drive wheels connect to axle mounts that are selectively positioned for track, camber, and height, which axle mounts connect to the chassis back. A seat support attaches to the chassis for supporting a person in the wheelchair and includes independently adjustable height, longitudinal position relative a seat back, and angle. A pair of push handles attach to the chassis back and pivotally connect to the seat support for selective positioning of the angle of the back.

    Abstract: This wheelchair incorporates a unitary supporting frame for the drive wheels and swivalable casters, and an adjustable seating assembly. The supporting frame is adjustable to change the wheelbase, track, and frame pitch and thereby shift the user's center of gravity and orientation with respect to the wheels. In a preferred embodiment provision is made for adjusting and maintaining the alignment of the wheels and casters. The seating assembly allows the seat and seat back to be positioned independently to suit the user's size, posture, balance, and other physical characteristics. A powered seat mount allows the user to raise and lower the seating assembly.
