摘要

This invention can be used PREFERABLY IN THE FIELDS OF MEDICINE AND SPORT IN MACHINES USED TO STRENGTHEN THE MUSCLES IN KNEE AND TRAINING OF KNEE. IN HIS VERSION simpler, the articulated joint comprises two plates (1, 2) which can move freely ATTACH over another, alternatively, a plate (1) or the other (2) can be attached to a fixed structure THROUGH A fastening device. One plate has two openings (2.2, 2.3), wherein the first opening (2.2) located in the center of a plate and is shaped like a rectangle. The second opening (2.3) has a specific shape: the beginning is a circle whose radius is equal to "I"; SUBSEQUENTLY IS A SPIRAL RETURNING TO THE CENTER OF THE PLATE (2). The other plate has two pins (1.2 and 1.3), at a distance "I"; The first pin (1.2) is located in the central part and inserted into the opening (2.2); The second pin (1.3) is in a peripheral position and stands at the second opening (2.3). Alternatively, the plate (2) can be replaced by several superposed plates (3, 4, 5, 6, 7); THE half-plates are arranged in overlapping COUPLES (4, 7 and 5, 6). LAS half plates (4, 7) are secured to the plate (3) by means of a pin (4.1) positioned at the point IDEAL ROTATION (11) AND SO ON MAY ROTATE FREELY half plates (5, 6).
