(54) ВЕЛО ТРЕНАЖЕР(54) LED TRAINING SIMULATOR

Изобретение отнсх:итс к устройствам дп тренировки велосипепистов в несеаонное врем года.Invention otnh: itc to devices dp training cyclists in the non-seasons.

, Известен вепотренажер, содержащий смонтированное на раме средство дл создани нагрузки, включающее установленные на раме ролики дл опоры колес .велосипеда, кинематически св - занные между собой tl.The known exercise machine contains a load-generating means mounted on the frame, including rollers mounted on the frame for supporting the wheels of the bicycle, kinematically connected to each other tl.

Однако втот вепотренажер имеет сложную конструкцию, так как средство дл создани нагрузки содержит также рот-орный насос, сообщающийс с жидкосртным резервуаром.However, this heating apparatus has a complex structure, since the load generating means also contains a rotary pump communicating with the fluid reservoir.

Цель изобретени - упрощение конструкции вепотренажера.The purpose of the invention is to simplify the design of a heat exchanger.

Поставленна цель достигаетс тем, что ведомый ролик имеет переменное сечение, одно из которых соответствует сеченик) ведущего ролика.The goal is achieved by the fact that the driven roller has a variable cross section, one of which corresponds to the cross section of the drive roller.

Кроме того, ведомый ролик может быть выполнен в виде усеченного конуса или ик1еть два цилиндрических участкаIn addition, the driven roller can be made in the form of a truncated cone or two cylindrical sections

разного сечени , соединенных между собой коническим участком.different sections, connected by a conical section.

На фиг. 1 изображен предлагаемый велотренажер в аксонометрии; на фиг. 2 и 3 - ведомый ролик, варианты вьшолне- ни .FIG. 1 shows the proposed exercise bike in axonometry; in fig. 2 and 3 - driven roller, options for execution.

Устройство содержит раму 1 и смонтированное в ней средство дл создани нагрузки, включающее установленные . на раме ведущие ролики 2 и 3 и ведомый ролик 4, кинематически св занный посредством гибкого элемента 5 с ведущим и имекший переменное сечение, одно из которых А-А соответствует сечению ведущего ролика (фиг. 2 и 3).The device comprises a frame 1 and a load generating means mounted therein, including the installed ones. on the frame there are leading rollers 2 and 3 and a driven roller 4, kinematically connected by means of a flexible element 5 to a leader and having a variable cross section, one of which A-A corresponds to the cross section of the leading roller (Fig. 2 and 3).

Ведомый ролик может иметь как форму усеченного конуса (фиг.З), так и форму двух цилкАдров 6 и 7 разного сечени , соединенных между собой коничес1ШМ участком 8.The driven roller may have the shape of a truncated cone (FIG. 3), as well as the shape of two cylinders 6 and 7 of different sections, interconnected by a conical section 8.

Пользуютс велотренажером следующим образом.Use the exercise bike as follows.

Claims

Wheels 9 and 1 of the bicycle are mounted on rollers. When pedaling, the rotation from the wheel 9 of the bicycle through the driving roller 2 and flexible input 5 is transmitted to the driven roller 4 and the wheel io of the bicycle. At the same time, the athlete pr "depresses the braking moment on the driven roller MT Р R в, where Р is the weight of the athlete and the bicycle that comes on the driven roller, and R is the radius of the driven roller. When installing a bicycle on different Hbife sections of the driven roller changes the nature of the workout, imitating both driving on flat terrain — when the driving and the driven rollers are equal, and driving uphill and downhill, when the driven roller’s cross section is correspondingly big EB1I mennip the sick Claims 1. An exercise bike containing a means for co-loading that is loaded onto a frame, including rollers mounted on the frame to support the wheels of the bike, kinematically interconnected, characterized in that, in order to simplify the design. variable settlement, one of which corresponds to the cross section of the leading roller.

2. The exercise bike according to claim 1, about the t of l and the fact that the driven rock is made in the form of a truncated cone.

3. The exercise bike of claim I, of which is that the driven roller has two cylindrical sections of different cross-section, interconnected by a conical section. Sources of information taken into account during the examination 1. USSR author's certificate No. 35373О, cl. A 63 B 69/16, 1970.
