Granted: 2018-08-07
Abstract: A powered wheelchair 100 with a tilt mechanism having multiple pivots that allows the wheelchair 100 to be driven and steered with or without the use of hands. The wheelchair 100 has two spaced apart drive wheels 101, each mounted to a separate shaft 104 that is independent of the other drive wheel. A drive controller drivingly coupled to the shafts 104 and the drive controller is housed within a base 102 that is pivotally situated on the shafts 104. A seat 103 mounted on a tilt mechanism enables the seat to tilt in a forward, backward, left and right direction as a result of the user displacing their body weight in either of those directions. The tilt mechanism includes three pivots, a primary pivot P1, secondary pivot P2 and tertiary pivot P3. The primary pivot P1 pivotally connects the base 102 to the shafts 104. The secondary pivot P2 is situated above and adjacent the base 102 so that the respective ends of the rod 105 are pivotally connected to the base 102. The tilt mechanism and the drive controller are connected to a weight displacement sensor to control the movement and direction of travel of the wheelchair 100. Both the primary and secondary pivots P1 and P2 allow the seat 103 to pivotally move in a forward and backward direction (103F, 103B) relative to the wheels 101 and such movement is sensed by the weight displacement sensor that in turn causes the drive controller to impart drive to one or both of the drive wheels to move the wheelchair 100 in the sensed direction e.g. forward or backward. The secondary pivot P2 enhances the offset of weight transfer by a user so as to cause increased control of the back or forward tilt (103F, 103B) of the seat 103 relative to the shaft 104 which is not possible with just a primary pivot P 1 . The tertiary pivot P3 is situated above the secondary pivot P2 and is situated below and adjacent the seat 103 so as to pivotally connect the respective ends of the rod 105 to the seat. Tertiary pivot P3 allows the tilt mechanism to tilt the seat 104 in left and right directions (103R, 103L) and the weight displacement sensor upon sensing left or right movement causes the drive controller to impart drive to one or both of the drive wheels to turn the wheelchair 100 left or right.

Abstract: A cam and groove coupling joint has a male coupling having a substantially tubular body that includes a pair of grooves in the body and a female coupling having a substantially tubular body that includes two pairs of lugs on the body and further includes pins that are supported by each pair of lugs. A pair of cam arms are pivotally mounted to the pins between the lugs. The cam arms are movable between an open position in which the male coupling is free to move relative to the female coupling and a closed position in which a cam of each cam arm engages the groove to lock the male coupling inside the female coupling. A wire clip secures the cam arms in the closed position, the wire clip being movable between a secured position in which the wire clip secures the cam arm to prevent opening of the cam arm and an unsecured position in which the cam arm is free to be opened, wherein the wire clip has a first segment of wire extending through holes in the lugs such that the wire clip is able to slide orthogonally with respect to the cam arm while being permanently mounted to the female coupling and wherein the wire clip has a second segment substantially parallel to the first segment that is extendable over the cam arm to secure the cam arm.
