20120273283 | MIDWHEEL DRIVE WHEELCHAIR WITH INDEPENDENT FRONT AND REAR SUSPENSION - A wheelchair includes a frame, and a front pivot arm pivotally mounted to the frame at a front pivot point, the front pivot arm having a caster for supporting the frame. A rear pivot arm is pivotally mounted to the frame at a rear pivot point, the rear pivot arm having a caster for supporting the frame. A ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction. | 11-01-2012 |
20120138376 | MIDWHEEL DRIVE WHEELCHAIR WITH INDEPENDENT FRONT AND REAR SUSPENSION - A wheelchair includes a frame, and a front pivot arm pivotally mounted to the frame at a front pivot point, the front pivot arm having a caster for supporting the frame. A rear pivot arm is pivotally mounted to the frame at a rear pivot point, the rear pivot arm having a caster for supporting the frame. A ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction. | 06-07-2012 |
20120013098 | WHEELCHAIR MODULAR REAR SUSPENSION - A modular rear suspension system resiliently supports a wheelchair. The system includes a suspension mount having an upper shackle and a link arm mount. The link arm mount of the suspension mount has an upper pivot and a lower pivot. An axle tube is configured to rotatably support a pair of rear wheels, and an axle tube clamp engages an end of the axle tube. The axle tube clamp has a pivot and a lower shackle. The axle tube includes a link arm tube mount having a pivot. An upper link arm is supported for pivoting movement between the link arm mount upper pivot and the link arm tube mount pivot. A lower link arm is supported for pivoting movement between the link arm mount lower pivot and the axle tube clamp pivot. A resilient member is pivotally connected between the upper and lower shackles. | 01-19-2012 |
20110172503 | Physiological Data Collection System - A physiological data collection system that includes a recorder box having a memory device. The recorder box is in communication with a plurality of external sensors and a plurality of internal sensors. The physiological data collection system further includes a speaker and a controller, each in communication with the recorder box. The controller is provided for controlling the operation of the recorder box. The physiological data collection system further includes a set of ancillary functions that support and improve data integrity, usability, cost effectiveness and reliability of the system. | 07-14-2011 |
20110089665 | Locking Cable Actuator - A cable actuator comprises a housing, a handle, and a locking pin. The handle is pivotally connected to the housing and is moveable between a released position and a locked position. The handle has a slot that terminates in a locking detent. The locking pin has a first end configured to pass through the slot and a second end configured to engage the locking detent. The locking pin is biased toward engagement with the locking detent such that when the lever is pivoted to the locked position, the locking detent aligns with the locking pin permitting the second end to engage the locking detent. | 04-21-2011 |
20100194162 | Wheelchair Having Pivoting Backrest Frame Assembly - A wheelchair comprises a base frame, a backrest frame and a hinge assembly. The base frame has first and second side frame members. The hinge assembly connects the backrest frame to a portion of the base frame for selective pivotal movement. The hinge assembly includes a locking mechanism configured to provide selective discrete locking positions of the backrest relative to the base frame. The locking mechanism includes a locking pin and a plurality of cooperating locking apertures. The locking pin is adapted to selectively engage one of the plurality of locking apertures to define a backrest angle relative to the base frame. One or more plugs are adapted to engage one or more of the plurality of locking apertures to prevent the locking pin from cooperating with the plugged locking aperture. | 08-05-2010 |
20100194071 | WHEELCHAIR HAVING HEIGHT-ADJUSTABLE AXLE MOUNTS - A wheelchair frame assembly comprises a frame member having a first leg adapted to support a seat and a second leg configured to support a caster wheel. An axle mounting assembly connects an axle tube to the frame member. The axle mounting assembly includes an axle tube mount, a frame mount, and a spacer. The spacer is configured to alter the distance between the frame member and the axle tube and transfer longitudinal forces between the axle tube mount and the frame mount. | 08-05-2010 |
20100132120 | Adaptive Seat Cushion Having A Pressure-Relieving Structure - A seat cushion system includes a seat cushion assembly and at least one supplemental pad attached to a portion of the seat cushion assembly. The seat cushion assembly and the at least one supplemental pad include chambers that may be filled with a fluid to provide isolation between a user and a wheelchair or other seating structure. | 06-03-2010 |
20100090437 | Wheelchair Comprising A Foot Support - A wheelchair comprises a pair of spaced apart side frame tubes and a pair of foot support frames. Each of the foot support frames has a first end configured to connect to the side frame tubes and a second end configured to receive a cross member. The cross member interconnects the second ends of the foot support frames and supports a foot support assembly. | 04-15-2010 |
20100052334 | PIN RELEASE ASSEMBLY - A pin release assembly comprises an outer housing that is held in place to allow the outer housing to only rotate. An inner spool is supported for axial movement in relation to the outer housing. Rotation of the outer housing axially moves the inner spool. The inner spool is operatively connected to a latch pin to selectively project and retract the latch pin. | 03-04-2010 |
20090145677 | PERSONAL MOBILITY VEHICLE HAVING A PIVOTING SUSPENSION WITH A TORQUE ACTIVATED RELEASE MECHANISM - A personal mobility vehicle includes a power-driven base unit that supports a suspension system. The suspension system includes a front suspension arm that supports a front caster wheel and includes a suspension stop. A drive unit is pivotally supported on the base unit by a torque arm. The torque arm selectively disengages the suspension stop to allow movement of the front caster wheel in response to the terrain traversed. | 06-11-2009 |
