Abstract

A roller ski comprising a foot plate (6) supported by a forward and a rear pneumatic rubber wheel (7, 8) and provided with rigid supporting members (9) arranged to support the user's leg laterally at a level between the foot and the knee and at the same time to allow the leg to move freely in the longitudinal direction of the roller ski.

Description

The invention relates to training devices for skiers in the zone zone season, in particular to roller skis. Known roller skis, containing a platform mounted on uniaxial wheels, a carrier fixed to the toe part of the boot and stabilization of the tibia, located above the platforms above the ski boot. Their disadvantage is inconvenient in use, because the stabilization of the torus stabilizer is connected with it through a cuff located under the knee and able to move both along the lower leg and twist, which can cause shrinkage of the lower leg, the appearance of abrasions on the skin and lead to incorrect movement of the skier. The purpose of the invention is to simulate the natural movements of the skier. The goal is achieved by the fact that in roller skis containing a platform mounted on uniaxial wheels, a carrier mount for the toe part of the boot and a shin stabilizer located above the platform above the tail shoe, the shin stabilizer contains two rigid arched frames fixed to the axles of the wheels and located on both sides the plate of the Form is symmetrical to its longitudinal axis. FIG. 1 shows a roller Alji side view; in fig. 2 - the same top view; in fig. 3 - skis in work. Roller skis contain a platform 3 mounted on uniaxial wheels 1 and 2, a carrier mount 4 of the toe part of the boot and a stabilizer 5 of the lower leg, located above the platform above the ski boot 6 and made in the form of two rigid frames 7 of arch shape fixed on the wheels x 8 and located on both sides of the platform is symmetrical to its longitudinal axis. The ends of the frames and the platform are formed at the junction of their holders in which the hubs of the wheels are fixed. The latter are preferably pneumatic and of sufficiently large diameter. Skis can have wings 9 over the wheels. The height of the frames is such that their upper parts are always located above the ski boot, regardless of the position of the foot. Since the stabilizer frames are located at the same mutual distance between the front and rear wheel hubs, the natural movement of the leg is ensured, as in conventional skis, when the foot rotates relative to the nose mount. When a skier moves, his legs are constantly supported from the sides by frames 6, which allows for training on terrain with different terrain and ground.

Claims (1)

ROLLER SKIS containing a platform mounted on uniaxial wheels, supporting the toe of the boot and the shin stabilizer located above the platform above the ski boot, with the exception of the fact that, in order to simulate the natural movements of the skier, the tibia stabilizer contains two rigid arched frames fixed on the axles of the wheels and located on both · sides of the platform symmetrically to its longitudinal axis.
