[0099] The leg load module 3 that is connected to the leg pedals 11 is mounted on the horizontal support 20.

[0100] The hand load module 2 that is connected to the hand pedals 10, the control unit 14, the user trunk support 25, the visual display device 19 are mounted on the console bar 21.

[0108] The hand load module 2 comprises the frame-shaped housing 4 in which the hand load unit 4, the shaft 8 of the hand pedals with the flywheel 39 which are kinematically interconnected by means of the belt drive 40 are mounted.

[0109] The rotational speed measurement means 12 for the shaft 8 of the pedal in the form of the apertured disc 42 that is secured on the shaft 8 and the optical pair being reflector-sensitive element 43 that is secured to the housing 4 is arranged on the bearing assembly 41 of the shaft 8 of the hand pedals with the flywheel 39 in the place of securing the circular rotation driving lever 44 of the hand pedal 10 to the shaft 8.

[0110] The hand pedals 10 which are configured as a system of levers which are interconnected by the pivots and which consist of the circular rotation driving lever 44 that is secured on the shaft 8, the horizontal telescopic lever 45 that is configured to adjust the movement of one portion of the lever relative to another one and of the vertical lever 27, are secured rightwards and leftwards on the shaft 8 of the leg pedals with the flywheel 39. The handle 46 of the hand pedal 10 is arranged on the horizontal lever 45.

[0111] The housing 4 with the assemblies mounted thereon may be equipped with the protective decorative envelope, thereby forming a visually unified module.

[0112] The power supply unit 47 may be arranged on the rear side of the top portion of the console bar 21.

[0113] The supporting frame 1 of the training machine, according to the first and to the second embodiments of the invention, may be equipped with the adjustment means, namely, with the knobs 48 for adjusting the mounting height of the trunk support 25, the knobs 49 for adjusting the ellipsoidal nature of the movement path of the hand pedals 10 due to the mutual movement of the telescopic elements of the horizontal lever 45, the knobs 50 for fixing the hand load module 2 on the console bar 21, the knobs 51 for adjusting the mounting height of the hand load module 2 on the console bar 21 depending on the user's height, the knobs 52 for adjusting the inclination angle of the telescopic supporting lever 22, the knobs 53 for adjusting the ellipsoidal nature of the movement path of the leg pedals 11 due to the mutual movement of the telescopic elements of the horizontal lever 36.

[0114] The training machine, according to the first embodiment of the invention, operates as follows.

[0115] The user stands on the foot rests 37 of the leg pedals 11, holds the handles 46 of the hand pedals 10 with his/her hands, and, if necessary, rests with his/her thorax onto the support 25 depending on the inclination angle of the trunk.

[0116] A certain load level is set on the load units 6 and 7.

[0117] The user begins to rotate the hand pedals 10 and the leg pedals 11 simultaneously. Upon the beginning of the rotation of the shafts 8 and 9 of the load modules 2 and 3, signals from the optical pairs 34 and 43 are transmitted to the control unit 14 constantly.

[0118] In view of the fact that the hand load module 2 and the leg load module 3 are not coupled mechanically, the users find it difficult to achieve and to maintain the synchronous rotation of the hand pedals 10 with the leg pedals 11 or to maintain the training mode with a preliminary defined asynchronous rotation of the pedals.

[0119] If there is a difference in the rotational speeds, then the control unit 14, using a comparator device known from the prior art, will determine the difference in the rotational speeds and will generate a signal, according to which, a signal to increase the load will be transmitted to the load unit of the load module that has a greater speed. The increase, as compared to the preliminary defined load, will be carried out via the increase of the current that is supplied to the corresponding load unit.

[0120] Said load increase is sensed by the user as a tactile feeling and begins to equalize the speeds, thereby achieving the synchronism or the defined level of the difference in the rotational speeds (asynchronism) of the hand pedals 10 and the leg pedals 11.

[0121] At the same time, the control unit 14 forms signals regarding the training parameters being a magnitude of the speeds, the load level, the training time for the visual display device 19 that is configured as a monitor (a touch screen).

[0122] The control unit 14 also may be configured using a microprocessor, thereby providing wide opportunities for selection, fixation, changing, and memorizing the training modes and changing the magnitude of the additional load caused by the difference in the rotational speeds of the pedals.

[0123] The training machine for the simultaneous training of the human shoulder girdle and the pelvic girdle and the trunk muscles, according to the second embodiment of the invention, as compared to the training machine, according to the first embodiment, further comprises, in each of the load modules 2, 3, the electric motor 15, 16 that is kinematically coupled to the load unit 6, 7 and to the shaft 8 and 9 of the corresponding pedals and is connected to the control unit 14. Therewith, the kinematic coupling may be configured using the mechanical or electromagnetic clutches 17 and 18.

[0124] Therewith, according to the second embodiment of the invention, the control unit 14 is configured to receive and to process the information regarding the rotational speed of the shafts 8 and 9 of the pedals 10 and 11, to switch on, to switch off, to adjust the rotation torque and to adjust the rotational speed of the electric motors 15, 16.

[0125] The presence of these features has provided the possibility of compensating the load momentums which objectively exist in the load modules without the load units due to friction. That is, it is possible to provide the movement of the pedals with a zero load or even with a negative load, when the pedals themselves move the user's hands and legs at the given speeds in the synchronous or asynchronous modes.

[0126] These modes may be used for the warm-up mode or for the rehabilitation training modes of the users having very fragile muscles.

[0127] Therewith, the training machine is configured to switch off the electric motors 15, 16 if there is no external contact with at least one pedal 10 and/or 11 which is very important in terms of the user's safety and makes his/her injuring impossible, e.g., if there are accidental situations or the individual feels unwell during the training. An information regarding an absence of this contact is transmitted to the control unit 14 due to the arrangement of the prior art sensors on the foot rests 37 of the leg pedals 11 and on the handles 45 of the hand pedals 10, the sensors are capable of generating a signal, when there is or there is no human hand or leg touch, or when there is a certain pressure. They may represent capacity sensors, strain gauges or a combination thereof.

[0128] Therefore, the claimed invention (variants) enables to increase the quality and the efficiency of the trainings significantly by providing the balanced involvement of all groups of the user's muscles and to select the optimal training mode depending on the user's fitness level and health state due to providing the multi-function effective training machine for training the human trunk muscles, shoulder girdle and pelvic girdle, which implements the possibility of synchronizing the movements made by the upper and lower limbs due to adjustment of the load level applied to the pedals depending on the efforts applied by the user, as well as to inclusion of the warm-up mode or the learning mode of the trainings with minor, zero or negative loads, when the pedals rotate without any efforts applied by the user both in the synchronous and the asynchronous rotation.

[0129] Therewith, the above-described exemplary embodiments of the invention should be used as an illustration only and should not limit the scope of the invention. Obvious modifications of the embodiment of the invention may be easily made by persons skilled in this field of art without falling beyond the essence thereof.
