(54) РОЛИКОВАЯ ЛЫЖА(54) ROLLER SKI

Изобретение относитс к спортивному инвентарю и касаетс конструкции роликоэой лыжи.FIELD OF THE INVENTION The invention relates to sports equipment and relates to the construction of a roller skier.

Известна роликова лыжа, содержаща установленное на колесах основание с расположенным на нем механизмом ограничени обратного хода колёс, выполненнЕлм в виде подпружиненного тормозного рычага, шарнирно соединенного с основанием, и поворотную платформу со спортивным креплением 1 .A roller skier is known, having a base mounted on wheels with a wheel restraint mechanism located on it, made in the form of a spring-loaded brake lever pivotally connected to the base, and a turntable with a sport mount 1.

Однако в известной роликовой лыже не обеспечиваетс получение различной отдачи (прокат назад), что не позвол ет имитировать толчок от м гкой и жесткой лыжни.However, in a known roller ski, it is not possible to obtain different kickbacks (rolled back), which does not allow imitating a push from a soft and hard track.

Целью изобретени вл етс приближение условий тренировки в несезон ,ное врем к естественным услови м 13ИМЫ путем имитации реальных фаз лыжного хода..The aim of the invention is to approximate the training conditions in the off-season, time to the natural conditions of 13% by simulating the real phases of a ski course.

Поставленна цель достигаетс тем, что в роликовой лыже, содержащей установленное на колесах основание с размещенным на нем механизмом ограничени обратного кода колес, выполненным в виде подпружиненного тормозного рычага, шарнирно соединенного с основанием, и поворотную платформу со спортйвным креплением, тормозной рычаг выполнен регулируемым по длине.The goal is achieved by the fact that in a roller ski containing a base mounted on wheels with a wheel restraint restriction mechanism placed on it, made in the form of a spring-loaded brake lever pivotally connected to the base, and a turntable with a sports mount, the brake lever is adjustable in length .

На фиг. 1 изображена роликова 5 лыжа, вид сбоку; на фиг. 2 - то же, вид сверху; на фиг. 3 - разрез А-А на фиг. 1; на фиг. 4 - разрез Б-Б на фиг. 1; на фиг. 5 - разрез В-В на фиг. 1; на фиг. 6 - разрез Г-Г на FIG. 1 shows a roller 5 ski, side view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. one; in fig. 5 shows a section B-B in FIG. one; in fig. 6 - section GG on

10 на фиг. 7 - разрез Д-Д на фиг. 4; на фиг. 8 - вид Е на фиг. 7. Роликова лыжа содержит основание 1, на котором креп тс кронштейны 2 и 3, подп тник 4 и шарнирно посажен15 ный хомут 5, на конце которого находитс крепление 6 дл спортивной обуви. Кронштейн 3 удерживает подшипник 7 (фиг. 3 и 4), на который опираетс ось 8 (фиг. 7). На концах оси 10 in FIG. 7 is a section d-d in fig. four; in fig. 8 is a view E of FIG. 7. Roller ski contains base 1, on which brackets 2 and 3 are fastened, bow 4 and a hinged clamp 5, at the end of which there is a fixture 6 for sports shoes. The bracket 3 holds the bearing 7 (Fig. 3 and 4), on which the axis 8 is supported (Fig. 7). At the ends of the axis

20 8 креп тс колеса 9 и 10, имеющие возможность вргицатьс независимо одно от другого за счет втулки 11. Кроме того, на кронштейне 3 шарнирно крепитс механизм ограничени 25 обратного хода. Этот MexaHHst содержит тормозной рычаг 12, шарнирно установленный на кронштейне 3, который жесткосв зан с основанием 1, причем ось поворрта рычага 12 смещена относительно оси вращени колес 9-и 10 The 20 8 wheels 9 and 10 are fastened, which can be independently independent of each other due to the hub 11. In addition, on the bracket 3, the backstop limiting mechanism 25 is hinged. This MexaHHst contains a brake lever 12, hinged on the bracket 3, which is rigidly attached to the base 1, and the axis of rotation of the lever 12 is offset relative to the axis of rotation of the wheels 9 and 10

Claims

30 to create a self-sealing effect. At the opposite end of the lever 12, an adjustable clamping bar 13 is fastened, passing into the brake caliper, which is pressed to the inner surfaces of the rims of wheels 9 and 10 by a spring 14. The contact point of the clamping plate 13 with the rims of the wheels is rubberized with a strap 15. The spring 14 is attached at one end to the bar 13, another to the bracket 16 belonging to the base 1. The bracket 16 has a number of holes for adjusting the tension of the spring. On the bracket 2 a wheel 17 is fastened (fig. 3), having the same diameter with wheels 9 and. 10. Roller ski works as follows. With a push (reverse) for friction and eccentricity of the levers 12, the presser bar 13 locks the wheels 9 and 10, while the levers are rotated along the radius R. By adjusting the radius R, the bar 13, you can reproduce different conditions of recoil of the roller ski from the soil cover, so as the departure, Rr changes the angle ot, which leads to different deformations of the rubber on the inner surfaces of the rims of wheels 9 and 10. This brings the training conditions in the off-season time to the natural conditions of winter. During the forward stroke, the bar 13 unlocks the wheels 9 and 10, allowing them to rotate freely. By adjusting the force of pressing the plank 13 to the inner surface of the rims of the wheels of the spring 14, various conditions of sliding of the ski along the track can be reproduced. To brake roller skid on any part of the track, you need to push the bracket 16 in the direction of the arrow G. After the push, the foot moves upward along the radius R due to the hinged clamp 18, without allowing the wheels 9, 10 and 17 to come off the ground. In the proposed roller ski, thanks to the simple reverse gear mechanism, it is possible to simulate various conditions of slip and recoil. The introduction of the brake provides a safety feature on. any sections of the track. An invention of Roller skis comprising a base mounted on wheels with a mechanism for limiting the return motion of the wheels, made in the form of a spring-loaded brake lever pivotally connected to the base, and a turntable with a sport mount, which is different in that with the aim of approaching the training conditions in the off-season, to the natural conditions of winter, by simulating the real phases of the stroke, the brake lever is adjustable in length.
