ABSTRACT:
A telescoping platform assembly able to convert each unit of distance moved by a driver into two, four, or greater number of units of platform extension includes five or more interconnected slide members. The interconnected slide members are extended by operation of a powered driver coupled to the second slide member cooperating with first, second, and third cable and pulley mechanisms. The first cable and pulley mechanism couples the first, second, and third slide members together so that the third slide extends twice as far as the second slide member. The second cable and pulley mechanism couples the second, third, and fourth slide members together so that the fourth slide members extends three times as far as the second slide member. The third cable and pulley mechanism couples the third, fourth, and fifth slide members together so that the fifth slide member extends four times as far as the second slide member. Thus, the first, second, and third coupling mechanisms cooperate to extend the platform four times the total extension of the second slide member. Fourth, fifth, and sixth cable and pulley mechanisms are similarly coupled to the slide members to retract the telescoping platform assembly from the extended position.
