COMBINED INCREMENTAL LIFT MACHINE

摘要

The present invention pertains to the field of sports and more precisely to that of incremental lift machines. The purpose of this invention is to increase the number of exercises which can be performed using a reduced-size apparatus and to improve the convenience as well as the safety conditions during the use thereof. The incremental lift machine of the present invention comprises an upper base and a lower base which are connected together by stands in the shape of guides, a cable and pulley system in which the pulleys are mounted on the upper base, a tackle block mounted on a carriage arranged on the guides, a cable connected to a set of loads, a rod mounted so that it can be fixed relative to the carriage and the loads, a plurality of fixation members as well as a set of sport accessories. This incremental lift machine is further fitted with a cable tension regulator. The cable and pulley system also includes a spring-loaded pulley which is mounted on the upper base. The rod is arranged so that it can be fixed relative to the upper base. The ends of the cable are fitted with stop safety hooks interacting with the pulleys on the upper and lower bases. The cable tension regulator consists of an eccentric hinge-lever mechanism in the shape of a parallelogram, wherein a pulley is mounted on the axis of one of the levers thereof. The cable tension regulator can also be made in the form of a pulley which is mounted on the rear wall of the carriage, which includes a stored cable capable of deflection and which is covered with a protection casing having open upper and lower portions.
