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.

Abstract: The present invention refers to a treadmill comprising a moving belt and holding means with the aid of which the weight of the user's body can be counterbalanced at least partially, said invention providing the feature that said holding means include at least one support means for weights which can be added one by one and which serve as counter-weights.

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.

Abstract: The present invention refers to a toothed-belt and V-belt for treadmills, comprising an endless belt, which is provided with a plurality of tread lamellae and which is guided around two deflection pulleys. At least one of the deflection pulleys comprises a sliding disk member and a toothed-disk member in juxtaposition, and the belt comprises, in juxtaposition, a toothed-belt area associated with the toothed-disk member of the deflection pulley and a V-belt area abutting on the sliding disk member of the deflection pulley. The main force for driving the belt is transmitted via the sliding disk member and the V-belt area. The toothed-disk member of the deflection pulley preferably has toothed areas and toothless areas, which are alternately and equidistantly arranged throughout the circumferential surface thereof.

Abstract: An elongated frame retains a pair of drums, sheaves, pulleys or the like, at the ends of the frame, one of which is preferably power driven; the movable surface includes a plurality of step elements which have a flat top surface, preferably covered with a resilient surfacing, such as foam rubber, carpeting, or the like, to form an endless flexible belt which may be a composite of an endless belting to which slats are secured. The slat elements span the width of the apparatus and, in cross section, preferably have T-shape. A series of back-up support rollers with lateral guide flanges are located beneath the upper run of the movable support surface, with at least one elastic cushion support between the rollers and the slats, for example formed of an endless rubber V-belt in contact with the lateral flanges of the support rollers to accept lateral forces arising in use.
