Pool Lift Portability Method and Apparatus

摘要

An apparatus is provided for rendering a pool lift portable. The apparatus comprises a forewheel assembly comprising a forewheel attached to a base of a pool lift adjacent a forward edge of the base, and a jack comprising a jack wheels. The jack may be attached to the pool lift base in a position where the jack wheel is spaced from the forewheel, and the jack may be actuated to alternately lift and lower the apparatus by alternately moving the jack wheel between extended and retracted positions so as to rotate the pool lift base about the forewheel such that the pool lift base is in contact with a supporting surface when the jack wheel is in its retracted position, and such that the pool lift base is supported in a transport position spaced from the supporting surface by the forewheel and the jack wheel when the jack wheel is in its extended position. The apparatus may include a seat attitude maintenance linkage comprising a single-side two-link crank linkage having a long link spaced to prevent pinching.

1. A pool lift portability apparatus comprising:
a first forewheel assembly configured to be attached to a pool lift base adjacent a forward edge of the pool lift base and comprising a first forewheel supported for rotation about a first forewheel axis; and a jack comprising a first jack wheel supported for rotation about a first jack wheel axis, the jack being configured for attachment to the lift base in a position where the first jack wheel is spaced from the first forewheel, the jack being actuable to alternately lift and lower the pool lift by alternately moving the first jack wheel between extended and retracted positions so as to rotate the pool lift base about the first forewheel axis, the pool lift base being in contact with a supporting surface when the first jack wheel is in its retracted position, and with the pool lift base being supported by the first forewheel and the first jack wheel in a transport position spaced from the supporting surface when the first jack wheel is in its extended position.
