Abstract: An anti-pushback mechanism for a wheelchair provides for a side mounted lever to allow the wheelchair to move in a forward motion only, a rearward motion only, or a neutral position where it can be pushed in any direction. This lever is connected to a ratcheting style gear that stops rollback when engaged. A torsion spring moves the chair forward slightly as the user stands to keep the chair close to the user and prevent falling. The invention may be provided as an add-on kit for existing wheelchairs. The kit would consist of a center axle, the ratchet gear, the torsion spring, the crossbar frame, the actuating lever, a guard for the lever, and any associated clamps and fasteners.

Abstract: A wheelchair anti-rollback device utilizes one-way roller clutches which incorporate a selectable free-rotation functionality such that the wheelchair user can select between anti-rollback and free-wheeling modes. The anti-rollback mode is of utility when the wheelchair user is propelling up ramps. The modal selection is by means of a knob positioned on the centerline rotation axis of the mechanism. The mechanism also included functionality that allows mode change from anti-rollback to free-wheeling to be made at any time, including while the chair is on an inclined ramp. The invention can incorporated into the hub of the rear wheels of a wheelchair or into the toggle mechanism of typically used to actuate parking brakes. When incorporated into a wheelchair, the invention gives the wheelchair user greater control and ease in ascending ramps.

Abstract: A hydraulic pump assembly for a hydraulic vehicle brake system includes a drive motor, preferably an electric motor, and a piston pump. The hydraulic pump assembly has a worm gear, preferably a ball screw unit, which converts a rotating output movement of the drive motor into a translatory drive movement of the piston pump or the pump piston. A method is provided for manufacturing the hydraulic pump assembly. A vehicle brake system includes the hydraulic pump assembly.

Abstract: A rotor turning system includes a fixture plate configured for attachment to a gearbox, a locking mechanism configured for attachment to the fixture plate, and a reaction fixture configured for attachment to the locking mechanism. The rotor turning system is configured to permit rotation of the rotor only when rotational torque is applied to the locking mechanism, and this rotation is in only one rotational direction.

Abstract: A transmission clutch module includes an inner race, an outer race, and a plurality of race engaging pawls adapted to selectively secure the races together in either a locked position or an unlocked position. The clutch module includes 5 an actuator cam configured to be moved between two angularly spaced positions to control the pawls. The inner race is comprised of two axially spaced inner race plates axially secured together by rivets for retaining, and accommodating angular limited movements of the pawls. The pawls are circumferentially disposed about the inner race plates, and are radially outwardly biased by springs 10 to engage the outer race, unless blocked by the actuator cam. The pawls are weighted at one end, so that at a threshold speed of the inner race, they can overcome spring resistance to disengage from both the actuator cam and the outer race.

Abstract: An actuator is provided for preventing rotation of a rotary component and includes a first pawl pivotable about a first pivot axis and engageable with the rotary component for preventing rotation of the rotary component in a first rotary direction. A second pawl is pivotable about a second pivot axis and engageable with the rotary component for preventing rotation of the rotary component in a second rotary direction opposite the first rotary direction. The pawls are each biased toward an engaged position with the rotary component by a pawl spring. A first and a second solenoid each include an electrically activated solenoid and an armature movable from a first position for holding the pawls out of engagement with the rotary component to a second position for allowing the pawls to be engaged with the rotary component.

Abstract: A mode selector mechanism for a selectable one way clutch assembly includes a lever moveable between a first position, a second position and a third position. A lever biasing device biases the lever in a first direction. A piston acts in opposition against the lever biasing device to move the lever in a second direction opposite the first direction. The piston is actuated by a variable hydraulic signal. The lever is disposed in the second position when the variable hydraulic signal includes a fluid pressure between a first fluid pressure and a second fluid pressure. The lever is disposed in the third position when the variable hydraulic signal includes a fluid pressure greater than the second fluid pressure. The lever is disposed in the first position when the variable hydraulic signal includes a fluid pressure less than the first fluid pressure.

Abstract: A parking brake apparatus may include a parking brake actuator that has a housing that is fixed to a transmission case and a piston including a piston rod, wherein the piston is mounted in the housing to reciprocate along the housing, a lever pivotally coupled to the transmission case, wherein one end portion of the lever is pivotally connected to the piston rod, a sprag rod that is pivotally connected to the other end portion of the lever, and an operational elastic member that is disposed around a rotary shaft of the lever and elastically supports the lever in one rotational direction against the transmission case, wherein the rotary shaft is rotatably coupled to the transmission case.

Abstract: A damper includes a frame, a main gear mounted to the frame for rotation about an axis of rotation, and a spring operably connecting the main gear and the frame such that rotation of the main gear tensions the spring. The main gear has a circumferential recess formed therein that defines a circumferential channel or reel. An elongated flexible member is wrapped around the main gear, disposed within the circumferential channel. A gear damper is mounted to the frame and is operably engaged with the main gear to dampen rotational movement of the main gear. The damper can be configured for one-way and two-way damping.

Abstract: A force-limiting rotary lock (20) for a shaft (21) mounted on a housing (22) for rotational and axial movement relative thereto, broadly includes a lug member (28) provided on the shaft, and a pawl (51) mounted on the housing. The pawl is movable relative to the housing between first and second positions. The pawl is operatively arranged to engage the lug when the pawl is in its first position (shown in FIG. 3) to prevent further rotation of the shaft in one angular direction, and to be disengaged from the lug when the pawl is in its second position (shown in FIG. 2) to permit rotation of the shaft in either angular direction. A cam (25) is mounted on the shaft, and a follower (49) is mounted on the housing for selectively moving the pawl between the first and second positions when the shaft is axially displaced from its predetermined position.

Each cabinet is fitted with an extendable privacy partition (80), an automatically deployed safety-spacer assembly (110), and is capable of accepting both factory-finished and custom-fabricated furniture and fixture infill packages (24) that provide the activity spaces (23) created in between the cabinets with all of the appurtenances necessary to particularize these spaces into functionally specific rooms. A continuous conductor rail (100) supplies power, telephone, and data to the residential program deck.

Abstract: A clutch assembly includes a driving member rotatable about a first axis; a pair of driven members, disposed on respective sides of the driving member for rotation about the first axis; and a pinion that simultaneously meshes with gear teeth defined on each driven member such that rotary power transmitted between the driven members through the pinion causes the driven members to rotate in opposite rotational directions. A coupling is disposed between the driving member and each driven member. Each coupling includes a strut that is selectively permitted to mechanically couple the driving member and a given driven member for rotation in one direction while permitting overrun in the other direction. Each coupling further includes a strut retainer that prevents the struts from mechanically coupling the driving member with the given driven member when the strut retainer assumes a predetermined rotational position with respect to the given driven member.
