摘要： An articulating leg rest is provided having a first member pivotally connected to a base frame. The base frame may be either connected to or part of a wheelchair frame. A second member is telescopically received by the first member. A drive system includes a motor-driven lead screw. First and second housings each have internally threaded portions engaged with the lead screw. A link connects the first housing to the base frame. The second housing engages the second member. Rotation of the lead screw advances the first housing along the lead screw, moving the link and causing the first and second members to rotate relative to the base frame. Rotation of the lead screw also advances the second housing along the lead screw, causing the second housing to linearly translate the second member relative to the first member.

摘要： A lift mechanism for a wheelchair includes a parallelogram linkage and an actuator for moving the linkage between a retracted position and an extended position to raise and lower a chair. One link of the linkage is slidingly engaged with a rail member. Movement of the linkage is constrained by another link such that as the chair is raised and lowered, the longitudinal position of an occupant's center of gravity relative to the wheelchair frame is substantially maintained. The lift mechanism may be combined with a tilt actuator to allow rotation of the chair. A chair tilt mechanism is also provided having a tilt actuator, a first link slidingly engaged with a rail member and a second link constraining movement of the first link. The tilt mechanism is capable of tilting the chair while substantially maintaining the longitudinal position of the occupant's center of gravity.
摘要翻译： 用于轮椅的提升机构包括平行四边形连杆机构和用于在缩回位置和延伸位置之间移动连接件的致动器以升高和降低椅子。 连杆的一个连杆滑动地与轨道部件接合。 连杆的运动被另一个连杆限制，使得当椅子升高和降低时，乘员重心相对于轮椅架的纵向位置被大体上保持。 升降机构可以与倾斜致动器组合以允许椅子的旋转。 还提供了一种椅子倾斜机构，其具有倾斜致动器，与轨道构件滑动地接合的第一连杆和第一连杆的第二连杆约束运动。 倾斜机构能够在大致维持乘员重心的纵向位置的同时倾斜椅子。

摘要： A pool jet fitting can include an insert housing defining an insert body, a housing channel, and a base disposed within the housing channel. The base can include an outer sidewall that defines an internal chamber. The fitting has a valve disposed within the internal chamber. The valve includes a valve body, a valve channel that extends into the valve body along the first direction, and a valve opening that extends through the valve body and into the valve channel along a second direction that is angularly offset with respect to the first direction. The valve is movable between a first position whereby the valve opening has a first area through which the water flow moves and a second position whereby the valve opening has a second area through which the water flow moves that is greater than the first area.
