  • Patent number: 8382646
    Abstract: The invention relates to a walking aid for a mechanically driven treadmill, comprising at least one tractive element that is guided over two respective deflection rollers and that is driven directly or indirectly by means of the treadmill. The tract of said element that directly faces the treadmill belt is displaced in the same direction as said belt and the tract of the element that faces away from the belt is displaced in the opposite direction to the latter. The aid also comprises at least one fixing element, which is located on the tractive element, for supports for part of the feet and/or legs.

  • Patent number: 6348025
    Abstract: A treadmill with at least one endless belt provided with a plurality of tread lamellae and guided around two deflection pulleys which are arranged one behind the other with parallel axes, the deflection pulleys being smooth in the area where they are in contact with the belt and at least one belt being implemented as a flat belt. Each tread lamella is provided with at least one engagement element projecting from the lower surface of the tread lamella. In addition, at least two stabilizers are provided, which are connected to the deflection pulley such that they are secured against rotation relative thereto, a stabilizer of this kind being in engagement with an engagement element on the lower surface of a tread lamella when the circumferential area of the deflection pulley, which rotates in synchronism with the stabilizer, is in contact with the at least one belt, and at least one stabilizer being always in engagement with the engagement element of a tread lamella.

  • Patent number: 5577598
    Abstract: In moving conveyors or treadmills with variable inclination, there is provided an apparatus for controlling the conveyor speeds, which apparatus comprises a brake band with the aid of which the circumference of a friction disk fixed for rotation with a driven shaft can be acted upon. With the aid of the control apparatus the moving conveyor is the more strongly braked the higher the inclination is that has been chosen for the moving conveyor so as to guarantee that the predetermined conveyor speed is always observed during operation.
