Mechanism and method for performing force impulses in tendon systems

Abstract

The subject of the invention is a mechanism and method for the implementation of assistive or resistive forces or force impulses in tendon systems during walking on a treadmill, which enables the implementation of the established method of training the maintenance of dynamic balance during standing or walking. The mechanism consists of a source (1) of rotary mechanical energy, which is mechanically connected to the mechanical axis (3) via an axial coupling (2), whereby the mechanical axis (3) is supported in two places by bearings (4), and on a mechanical axis (3) a winding reel (5) is attached in a fixed manner through the central roller (5'), and in which between the sides of the winding reel (5) eccentrically with respect to the axis of rotation of the reel (5) a tensioning cylinder (5") is installed in a fixed manner. The central roller (5') and the tension roller (5") of the winding reel (5) are concentrically embraced by the cylinders (6, 7), each of which can rotate freely around its own roller. Through the gap between the central roller (5') and the tension roller (5") passes and moves freely in the tangential direction relative to the central cylinder (5') a rigid tendon (8), which is at one end attached to the cuff (14), which embraces the selected segment of the human body, and on the other end is connected with a connecting joint (9) to an elastic element (10) of weak stiffness, which provides tension to the tendon (8) and which is attached directly or indirectly to a fixed point (12) at the opposite end via the pulley (11) or the tensioning of the rigid tendon (8) can also be done in such a way that instead of the elastic element (10), the rigid tendon (8) is directly connected either to an elastic element of constant stiffness or a weight is suspended on it via a pulley.
