Embodiment Construction

[0029]Referring to the above figures, the brake assembly of the invention, generally designated by numeral 1, will be advantageously fitted, as shown in FIG. 7, to a exercise cycling apparatus A.

[0030]The exercise apparatus comprises a support frame B for the rear wheel of a bicycle, attaching means M for securing the wheel hub to the frame B, a roller C designed to come in contact with the wheel to be rotated by a user through the application of a torque and the brake assembly 1 designed to generate a resistance torque opposing the user-applied driving torque.

[0031]As shown in FIG. 1, the assembly 1 basically comprises rotor means and stator means, generally designated with numerals 2 and 3 respectively, which are enclosed in two protective casings G and G′, which also contain the roller C.

[0032]A pair of magnetic elements 4, 4′ are associated to the rotor means 2, which include a support disc 11, and are designed to be rotated about a longitudinal axis X through the action of a us...

Abstract

A brake assembly for exercise cycling apparatus comprises rotor means (2) with at least one pair of magnetic elements (4, 4′) adapted to be rotated about a longitudinal axis (X) by a user who applies a driving torque thereon, stator means (3) adapted to cooperate with the at least one pair of magnetic elements (4, 4′) to generate a resistance torque adapted to oppose the above driving torque, guide means (7) associated to the rotor means (2) to cause translation of the magnet elements (4, 4′) along respective directions (d, d′) having at least one radial component to cause variation of the resistance torque proportionally to the driving torque. The magnetic elements (4, 4′) are reciprocally coupled to make the displacement thereof along directions (d, d′) mutually dependent and with substantially the same length (l, l′).

Description

FIELD OF THE INVENTION[0001]The present invention finds application in the field of sport and leisure accessories, and particularly relates to a balanced magnetic brake assembly for exercise cycling apparatus.[0002]The invention further relates to an exercise cycling apparatus incorporating such assembly.BACKGROUND OF THE INVENTION[0003]Exercise cycling apparatus are known which essentially comprise a support frame having a bolt for locking the hub of the rear wheel of a bicycle so that the latter can rotate by contact engagement with a horizontally extending roller by applying a driving torque which is variable according to the pedaling force exerted by the user.[0004]Such roller is braked by a brake assembly suitable to generate a resistance torque opposing the applied driving torque to simulate a more or less difficult route, thereby training the muscular and cardiovascular systems of the user. The resistance torque is typically generated by various types of means: mechanical, hy...
