FIELD: mechanics. ^ SUBSTANCE: fitness system loader consists of a base structure, two holders (the adjusting one and the sliding one) mounted on mutually opposite sides of the base structure by way of one end of each holder being attached to the base structure, a working element and a drive element. The base structure consists of a frame, lateral stoppers and a bow positioned within a plane perpendicular to the frame with the bow arc centre positioned on the straight line coinciding with the adjusting holder fixation axis; the adjusting holder free end is equipped with a device interacting with the bow so that to enable smooth slide along the latter and stepless lock of the adjusting holder position. The sliding holder is attached onto the base structure opposite the frame, positioned on an axis parallel to the adjusting holder fixation axis. The working element ends are attached to the free ends of the adjusting holder and the sliding holder. With the holders in the neutral position the axis of the adjusting holder fixation to the frame coincides with the axis of the working element fixation to the sliding holder. ^ EFFECT: smooth load regulation. ^ 2 dwg |
