DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention provides a resistance mechanism with improved stability for ski simulation equipment, which uses a plurality of springs that have wear protection elements at their ends, which reduce the stresses caused by anchoring on the base elements of the equipment and the exercise platform so that the terminations of said springs do not undergo alterations or lose their tenacity, which significantly increases the useful life of said elements. In addition, the resistance mechanism with improved stability for ski simulation equipment of the present invention is designed to transmit the forces applied on the rails of the ski simulation equipment directly to the ground of support, so that vibration is reduced of the rails and the use of the equipment by users of greater weight is allowed.

[0018] To achieve the above, the resistance mechanism with improved stability for ski simulation equipment of the present invention is made up of a reinforcing frame (I) and a sliding platform (II), adapted to be used in ski simulation equipment (A) that have a base made up of two transversal ends (a and a) joined together by a bridge (b). Said reinforcing frame (I) and sliding platform (II) will be described in more detail below.

Reinforcing Frame (I)

[0019] The reinforcing frame (I) is made up of two convex tubulars (1) that have anchoring bases (la) at their ends and lower reinforcing arches (2) arranged on their concave surface, said lower reinforcing arches (2) being joined at its distal end, by a crosspiece (3) that has on its lower surface, a pair of cylinders made of elastomeric material (4); an anchoring block (5) with a receiving tubular (6), which has at its ends, threaded locks (7) that allow said receiving tubular (6) to be extracted from the anchoring block (5) and; a folding lock (8), attached in a swinging way by screws to the anchoring block (5), which has a pedal (9) at its lower end and an elongated arm (10) with a terminal hook (11) at its other end. Said reinforcing frame (I) is adapted to be attached by screws to the transversal ends (a and a) of the base of the ski simulation equipment (A) using the anchoring bases (1a), in this way any force applied on the convex tubulars (1), it is transmitted along them and sent to the supporting ground through the lower reinforcement arches (2) and the anchorage bases (1a), in such a way that each one of said convex tubulars (1) has 3 force discharge points, which significantly increases the stability of the ski simulation equipment, reducing the vibrations caused by the exercise routines and also increases the structural force, so the equipment can support users weighing up to 150 kg without suffering deformations, consequently increasing the safety of the ski simulation equipment.

Sliding Platform (II)

[0020] The sliding platform (II) is made up of two support structures (12) each one with two perpendicular square profiles (13a and 13b) that receive bearings (14) between them and an absorption block (14a) arranged in its distal end to prevent the sliding platform (1) from crashing against the transversal ends (a and a) of the base of the ski simulation equipment (A); a connection stringer (15) designed to join the support structures (12) together by means of screws, which has a perpendicular tubular in its middle part (16) with threaded locks (17) at its ends; a plurality of springs (18) that each provide 20 kg of resistance, with terminal rings with O-rings (19), adapted to be received in the perpendicular tubular (16), being secured to it by the threaded locks (17), in such a way that when the sliding platform (II) is placed on the reinforcement frame (I), the free ends of the springs (18) can be anchored to the receiving tubular (6) in a separable way, securing them by means of the threaded locks (7); an anchoring bar (19) arranged in one of the absorption blocks (14), adapted to interact with the terminal hook (11) of the elongated arm (10), so that when pressing the pedal (9) of the folding lock (8), said terminal hook (11) is connected to the anchoring bar (19), blocking the sliding platform (II) on the reinforcing frame (I), to allow a user to climb onto the ski simulation equipment and; a pair of anchor points arranged in the support structures (12), designed to store the springs (18) when they are not used.

[0021] Likewise, the sliding platform (II) can also comprise a pair of casings (20) and (21), adapted to cover the adjacent ends of the perpendicular square profiles (13a and 13b) of the support structures (12) in order to serve as anchor points for tilting pedals.

[0022] In order to demonstrate the advantages of the resistance mechanism with improved stability for ski simulation equipment of the present invention, a comparative study was carried out in which a ski simulation equipment with a resistance mechanism of elastic bands with conventional support frame and resistance mechanism with enhanced stability of the present invention. In said study, both equipment underwent a stress test in which their platform was oscillated for 50,000 cycles by placing a 70 kg weight on it, monitoring the entire test with seismographs attached to the equipment bridge. Once the stress test was completed, the elastic bands and springs (18) were subjected to a traction test in which the traction force of said elements was assessed after being subjected to the stress test, comparing the results with the obtained with bands and springs (18) that were not subjected to the stress test. Likewise, a visual inspection was carried out to assess the presence of cracks and deformations in the bands and springs (18) after being subjected to the wear test.

[0023] After the comparative study was carried out, it was observed that the bands used in the wear test lost 45% of their traction force with respect to the bands used as a reference pattern and presented cracks along their surface. In contrast, the springs (18) subjected to the same treatment did not present a decrease in their tensile strength, and no cracks or alterations were observed on their surface after their visual inspection. It should be noted that the vibration level in both equipments during the test was significantly different, presenting a reduction of approximately 70% of the vibration in the equipment that used the resistance mechanism with improved stability of the present invention, with respect to the readings obtained by the equipment with bands.

[0024] On the other hand, both equipments underwent a load resistance test with dead weight, in which bags with weights were placed on the equipment platforms, increasing the load of the same of 5 by 5 kg. After each weight increment, a visual inspection of the equipment rails was performed and deviations in their curvature were measured. The equipment with bands and conventional frame, presented a deviation in the curvature of its rails from a weight of 125 kg, while the equipment with the resistance mechanism of the present invention presented a deviation in the curvature of its rails until reaching the 155 kg.

[0025] The aforementioned results show that the use of the resistance mechanism with improved stability for ski simulation equipment of the present invention significantly reduces the vibration of the equipment compared to the conventional mechanism of elastic bands, observing a decrease of up to 70% in vibrations and, furthermore, it prevents the loss of tension in the equipment, since even after 50,000 repetition cycles, the springs (18) of the resistance mechanism of the present invention maintain their traction force.

[0026] The present invention has been described in accordance with a preferred embodiment; however, it will be apparent to a technician with average knowledge in the matter, that modifications may be made to the invention, without departing from its spirit and scope.
