(54) ТРЕНИРОВОЧНОЕ УСТРОЙСТВО(54) TRAINING DEVICE

Изобретение относитс к устройствам , предназначенным дл лечебной гимнастики. Известно тренировочное устройство, содержащее опорную раму и установленные на ней педальный привод с валом , тормоз, дополнительный тормоз, инерционный механизм и средство дл переменного нагружени Педателй 1. Недостатком известного устройства вл етс то, что оно не обеспечивает возможность тренировки с переменной . нагрузкой одной или двух конечностей Целью изобретени вл етс повыше .ние эффективности тренировки. . Указанна цель достигаетс тем, .что средство дл переменного нагружени педалей состоит из маховика, установленного на валу и взаимодействугацего с тормозом, дополнительным тор .мозом и инерционным механизмом, причем рабоча поверхность маховика выпо нена в виде плавньтх сопр жений поверх ностей выступов и впадин, а дополнинительный тормоз вьтолнен в виде под пружиненной колодки, несущей ролики, установленные от ее поверхности -трени на величину меньшую глубины -поверхности впадины маховика. Кроме Того, инерционный механизм состоит из дисков и соосно св занного с ними ролика, закрепленных на опорной раме посредством подпружиненной штанги, причем ролик контактирует с рабочей поверхностью маховика. На фиг. 1 - изображено тренировочное устройство/ общий вид; на фиг. 2то же, вид сверху; на фиг. 3 - положение маховика и дополнительного тйрмбза в момент создани малой нагрузки; на фиг.4 - положение маховика и дополнительного тормоза в момент создани большой Нагрузки; на фиг. 5 - разрез А-А на фиг. 3; на фиг. 6 - разрез Б-Б на фиг. 4. Тренировочное устройство состоит из опорной рамы 1, спинки 2 кровати, на опорной раме посредстве кронштейна 3 закреплена вилка 4, в которой установлен вал 5 педального привода 6 с шатуном 7. На валу установлен маховик 8, св занный с роликом 9 и дисками 10, закрепленных на штанге 11. Штанга соединена с пружиной 12, обеспечивающей посто нный прижим ролика к маховику. Колодка 13 и колодка дополнительного тормоза 14 закреплены на кронштейне. Усилие поджати регулируетс винтами 15 и 16. А колодкаThe invention relates to devices for therapeutic gymnastics. A training device is known which contains a support frame and pedal drive with a shaft, a brake, an additional brake, an inertial mechanism and means for variable loading of the Pedal 1 mounted on it. A disadvantage of the known device is that it does not provide the possibility of training with a variable. load of one or two limbs. The aim of the invention is to increase the effectiveness of training. . This goal is achieved by the fact that the means for variable loading of the pedals consists of a flywheel mounted on a shaft and interacting with a brake, an additional torus and an inertial mechanism, and the working surface of the flywheel is designed in the form of smooth joints of surfaces of protrusions and depressions, and The additional brake is made in the form of a spring-loaded pad, which carries rollers installed from its surface — a length less than the depth of the surface of the flywheel hollow. In addition, the inertial mechanism consists of disks and a roller coaxially connected with them, fixed to the support frame by means of a spring-loaded rod, the roller in contact with the working surface of the flywheel. FIG. 1 shows a training device / general view; in fig. 2 same, top view; in fig. 3 - the position of the flywheel and additional tyrmbza at the time of creating a small load; Fig. 4 shows the position of the flywheel and the auxiliary brake at the time of the creation of a large Load; in fig. 5 shows section A-A in FIG. 3; in fig. 6 is a section BB in FIG. 4. The training device consists of a support frame 1, a backrest 2 beds, a fork 4 is fixed on the support frame by means of a bracket 3, in which a shaft 5 of a pedal drive 6 with a connecting rod 7 is mounted. A flywheel 8 connected to a roller 9 and discs 10 is mounted on the shaft mounted on the rod 11. The rod is connected to the spring 12, providing a constant clamp roller to the flywheel. The block 13 and block of an additional brake 14 are fixed on an arm. The clamping force is adjusted by screws 15 and 16. And the pad

Claims

745529 of the additional brake is equipped with two rollers 17. On the flywheel there are P oversides of the depression 18 and the protrusion 19. The device works as follows PtLSOtt. . When the pedal drive is arated, the flywheel 8 is set in motion. The pad 13, pressed with the screw 15 to the lead of the protrusion G9, provides a ps-load. With further rotation, the rollers 17 roll off from the surface of the vyptup 19 and the pad of the additional brake 14 is turned on, ... THIS IS SEEDING DOUBLE LIGHT ON THE LOAD. As a result of the rotation of the flywheel 8, the roller 9 is rotated and the disks 10 which facilitate the transition of dead flywheel points. . . Claims 1. A training device, including a support frame K, is mounted on it with a pedal drive with a shaft, a brake, an additional brake, an inertial mechanism and a means for variable loading of pedals, so that The purpose of increasing the training efficiency is to alternately load the pedals. It consists of a flywheel mounted on the shaft and interacting with the brake, an additional brake and inertial mechanism, the working surface of the Vypolnen VB meticulous soft coupling and the additional brake is made in the form of a spring-loaded shoe carrying rollers installed from its friction surface by an amount shorter than the surface depth of the flywheel cavity.

2. The device according to claim 1, which is based on the fact that the inertial mechanism consists of disks and a roller coaxially connected with them, fixed to the support frame by means of a spring-loaded rod, and the roller is in contact with the working surface of the flywheel .
