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.

摘要： In accordance with an embodiment, a pool jet fitting can include a housing and a redirector coupled to the housing. The housing can include a housing body and a bore that extends through the housing body along a first direction. The bore is configured to receive a water flow. The redirector is disposed within the bore of the housing. The redirector can define an opening through which the water flow moves. The redirector can include an actuator that is configured to automatically move the opening from a first configuration to a second configuration upon application of heat to the water flow by a heater. The water flow through the opening has a first trajectory when the opening is in the first configuration and a second trajectory when the opening is in the second configuration. The second trajectory is different than the first trajectory relative to the first direction.

摘要： A curb-climbing rear wheel drive power wheelchair is disclosed having a pair of drive wheels, at least one ground-engaging idler wheel connected to the frame forward of the drive wheels and at least one anti-tip wheel mounted above ground aft of the drive wheels. Each drive wheel and an associated drive assembly are mounted to a motor support bracket that is pivoted to the frame of the wheelchair. The drive assembly is mounted such that its motor is angled upward and rearward from the bracket. The anti-tip wheel is attached to one motor support bracket such that pivoting of the motor support bracket causes vertical displacement of the anti-tip wheel.

摘要： A power wheelchair is provided having one or more anti-tip wheels for stabilizing the movement of the frame about the drive wheels. An anti-tip wheel is attached to the end of a suspension arm which is pivotally attached to the frame of the wheelchair. A spring resiliently supports the anti-tip wheel in a neutral position relative to the ground upon which the drive wheels of the wheelchair normal ride. A retaining system selectively fixes position of the anti-tip wheels relative to the frame. The retaining system employs a plurality of teeth, with one portion disposed in combination with said suspension arm, and at least one other tooth disposed for engaging said one portion to provide unidirectional retention of the position of said suspension arm relative to the frame. The engagement of the teeth to lock the position of the suspension arm may be responsive to the torque generated by the motor.

摘要： A bi-directional anti-tip system for a wheelchair includes a pair of anti-tip system subassemblies actively lifting a leading anti-tip wheel when traveling in either forward or reverse directions. The anti-tip system subassemblies operate to couple a leading anti-tip wheel to the drive assembly such that pivot motion thereof effects vertical displacement of the leading anti-tip wheel and to decouple a trailing anti-tip wheel from the drive assembly to null pivot motion inputs therefrom. In one embodiment, rheonetic links actively couple and decouple the anti-tip system subassemblies. The system may also include compliant bearings or extensible links for inward displacement of the anti-tip wheel upon impact with a curb.

摘要： An anti-tip system is adapted for use in a powered wheelchair for purposes of curb-climbing and ride stability. The anti-tip system includes at least one anti-tip wheel, a suspension arm for mounting the anti-tip wheel and a pair of links coupling the suspension arm to the main structural frame of the wheelchair. Each of the links is pivotally mounted to the main structural frame of the wheelchair about a first pivot point and is pivotally mounted to the suspension arm about a second pivot point. In a first embodiment of the anti-tip system, the links include an upper and lower link, wherein the upper link is extensible to facilitate angular displacement of the suspension arm to permit rearward displacement of the anti-tip wheel in response to an externally applied load.

摘要： An anti-tip system is provided for improving the stability of a powered vehicle, such as a powered wheelchair. The vehicle includes a drive-train assembly which is pivotally mounted to a main structural frame. A suspension system biases the drive-train assembly and its connected anti-tip wheel to a predetermined resting position. The drive-train assembly bi-directionally rotates about a pivot in response to torque applied to or acceleration forces on the vehicle. A linkage arrangement is provided and is characterized by a suspension arm pivotally mounting to the main structural frame about a pivot at one end thereof and an anti-tip wheel at the other end. The linkage may further include at least one link operable to transfer the bi-directional displacement of the drive-train assembly to the suspension arm. The link may include a bell crank member and/or may be resiliently compressible.

摘要： An active anti-tip system is provided for a wheelchair having a main structural frame and a drive assembly. The anti-tip system includes at least one anti-tip wheel, a suspension arm assembly pivotally mounting the anti-tip wheel to the main structural frame, a pendulum mount for coupling the drive assembly to the main structural frame and intermeshing gears for conveying the motion of the drive assembly to the suspension arm assembly. The pendulum mount causes the drive assembly to traverse in a substantially horizontal path in response to torque input from the drive assembly. The motion of the drive train assembly is converted to pivot motion of the suspension arm by the intermeshing gears. The pivot motion of the suspension arm assembly causes the anti-tip wheel to be raised for curb/obstacle climbing and effectively lowered for pitch stability.
