Abstract:
Wheelchair drive boost apparatuses, drive assisted wheelchairs, and wheelchair drive boost systems are disclosed. A wheelchair drive boost apparatus includes a housing, a drive wheel including a drive axis that is movable with respect to the housing, a drive lever that engages with the drive wheel to cause the drive wheel to rotate, a transmission that couples the drive lever to the drive wheel, and an engager having a first position and a second position. The engager is configured to move the drive axis with respect to the housing.

Claim (Index 37):
A wheelchair drive boost system comprising:\n a wheelchair comprising a first main wheel and a second main wheel; a first wheelchair drive boost assembly comprising a first drive lever, a first drive wheel frictionally contacting the first main wheel, and a first transmission that couples the first drive lever to the first drive wheel via a first one-way engagement mechanism; and a second wheelchair drive boost assembly comprising a second drive lever, a second drive wheel frictionally contacting the second main wheel, and a second transmission that couples the second drive lever to the second drive wheel via a second one-way engagement mechanism, wherein:\n a forward movement of the first drive lever causes the first drive wheel to propel the first main wheel forward and a forward movement of the second drive lever causes the second drive wheel to propel the second main wheel forward, and \n the first transmission and the second transmission each multiply the respective forces applied to the first drive lever and the second drive lever to increase a force of the forward movements of the respective first main wheel and second main wheel.
