Description

Technical field

The invention relates to a fitness machine comprising a fixed frame with a left side panel, a right side panel and a front handle, wherein the fixed frame accommodates two parallel tracks, the running surface of which is shaped into a continuous concave arc and the running surface of the tracks .

BACKGROUND OF THE INVENTION

A number of fitness and exercise equipment and machines lack equipment that would imitate the movement of an athlete on a snowboard or downhill skis. At the same time, this movement is very suitable for loosening the lumbar and pelvic area and it would be appropriate to practice this movement skill in connection with rehabilitation exercises and the like.

US 2006179938 A1 discloses a leg force measuring device for assessing the needs of an athlete in the selection of skis, snowboard, ski boots. However, the device is not suited to induce cyclic relaxed movement, which is in turn required of the fitness machine.

EP 1510236 B1 discloses a training device for downhill skiers and snowboarders. The device allows simulation of edging on a ski and snowboard simulator and ascertaining the force action of the trainer on the simulator. Also, this device does not allow the movement to imitate skiing or snowboarding.

The essence of the technical solution

The aim of this technical solution is to design a device that would allow easy access to tools and variability of exercises, especially with a focus on skiing and snowboarding.

The object of the invention is achieved by a fitness machine according to the invention, which consists in that each treadmill comprises two traverses detachably detachable with a tread plate, each tread plate being connectable with two travels mounted on one track or with two travels each of which is stored on a different lane.

The device allows the practitioner to perform sliding movements of the legs along the paths, thereby achieving appropriate movements of the spine, head, etc. The practitioner has a secure support in the parts of the frame that surround it and which can be held in various ways. The walk-in trolley contains two traverses connected detachably to the walk-on plate. The unification of the travels increases the series production of the travels, bringing the following additional advantages, which result from the fact that the travels of one pedestrian trolley can be connected to the pedal pad so that the pedal trolley is supported by both traverses the trolley is supported by its travels on both lanes transversely to the direction of their length. This makes it possible to broaden the variations of the exercises in principle, since by simple adjustment the machine can be used in the position of the trainee facing in the direction of the lanes and their curves, or standing sideways to this direction.

Preferably, each track is formed by two parallel running surfaces. It is particularly advantageous if the running surface is in this case formed by a tube of circular cross-section. Such a design guarantees the stiffness of the tracks and the stability of the means of travel and thus also of the trainer.

Sufficient stiffness of the tracks and stability of the travel means is also achieved if the travel track is formed by a flat profile in whose upper surface two parallel grooves are formed in the direction of the flat profile for the travel wheels of the treads.

In addition, the walk-in trolley can be coupled with an adjustable brake that can be used to change the load that the practitioner has to exercise.

- 1 GB 26530 U1

The exercise can also be modified due to the fact that at least one travel is provided with an eye by means of which it is possible to lock the treadmill in a fastening sleeve fixed to the machine frame. In this way, essentially one foot tied to the treadmill can be locked against the track and only one foot can be used to move the body. In this connection, it is furthermore advantageous if at least two fastening sleeves are fixedly connected to one another in the direction of the length of the travel path. This allows you to change the position of the tethered leg relative to the curved track after a period of exercise.

Further features and advantages of the technical solution are defined in other dependent protection claims.
