STATE OF THE TECHNIQUE

[0002] Currently, within sports training, the adaptation of the training load to the specific moment of an articular movement developed by a subject who is performing training exercises is becoming increasingly important.

[0003] Likewise, in the functional recovery of a subject, which presents a temporary or permanent functional limitation, the improvement of muscle tissue plays a very important role depending on the application of loads for performing repetitive exercises with loads or weights in the body. weather. [0004] One of the most studied aspects, in strength training and functional recovery, is how to adapt the load to the joint angle of the bone levers involved in the movement, as they are elements that will condition the final result of the work done.

MODE OF REALIZATION

[0017] In relation to Figures 1 to 3, where a training device for applying a fixed or variable load is shown, depending on the collection of torque data in the array, controlled vertically. The device The training device is an electromechanical device comprising a clamping frame to which a motor of the servomotor type 1 1 is mechanically fixed, which drives a first axis 12 of rotation to which a first 21 cogwheel or pinion wheel and a clutch 22 transmitter is mechanically coupled. free wheel. [0018] The servomotor 1 1 rotates counterclockwise, that is, the direction of rotation and torque applied is counterclockwise, so that the clutch 22 is locked when the first 12 axis rotates counterclockwise.

[0019] The freewheel transmitter clutch 22 is also mechanically coupled to a braking or brake device so that a first 14 piece of the brake is mechanically coupled from its inner part to the outside of the transmitter clutch 22.

[0020] When the clutch 22 is locked, the first 14 piece of the brake also rotates jointly with the transmitter clutch 22.

[0021] One end of the first 14 part of the brake comprises a set of gear teeth by means of which it is also mechanically attachable to a gear tooth assembly of a second 13 part of the brake.

[0022] If the second 13 piece is engaged with the first 14 piece of the brake, it prevents the first 21 pinion from turning.

[0023] The second 13 part of the brake is mechanically fixed to the support frame of the training device by means of a fixing assembly 31 comprising a set of fastening parts and fasteners of the pin type.

[0024] However, the second 13 part of the brake has a degree of freedom to move horizontally to and from the first 14 part of the brake so that the first 14 part of the brake can be mechanically coupled to stop the circular movement of the first 12 axis.

[0025] An actuator device 51 of the solenoid type is mechanically coupled to the second 13 part of the brake to provide a control movement of coupling or disengagement of the first 14 part of the brake depending on the selected operating mode, ie mode of operation. selected training for the subject that is interacting with the device training.

[0026] The first 21 pinion cooperates mechanically with a second 32 cogwheel or pinion to transmit the turning movement of the first 12 axis to a second 33 axis of rotation. The transmission of the turning movement is carried out through a transmission 34 of the roller chain type.

[0027] The second 33 axle comprises a third 36 cogwheel or pinion at the end proximal to the skate 41.

[0028] The second 32 pinion is integrally coupled with a freewheel receiver clutch assembly 35 that locks when its axis rotates clockwise or clockwise.

[0029] Skate 41 includes a fourth 43 pinion and a fifth 44 pinion; a linear bearing 45 that runs longitudinally a vertical guide 46 at the lower end of which an absorber of the compression spring type fixed to the clamping frame has been arranged, so that in case the skate 41 lowers without any brake, the compression spring cushion the fall of the skate and avoid the breakage of any element of the training device.

[0030] A sixth 37 pinion bearing a bearing incorporated is attached to the clamping frame in such a way that a transmission of the open roller chain type 42 and whose ends are mechanically fixed to the clamping frame of the training device, cooperates with the third , fourth, fifth and sixth sprockets 36, 37, 43, 44 so that the skate 41 performs an upward or downward vertical movement guided by the guide or vertical bar 46.

[0031] The receiver clutch 35 is locked when its outer part rotates counterclockwise, dragging a second 33 axis in a turning movement which, in turn, vertically displaces a slider or skate 41 by means of a second pinion 32 .

[0032] Therefore, when the second pinion 32 rotates counterclockwise, the skate 41 moves vertically downward. Consequently, the servomotor 1 1 supplies a rotating movement which is transformed into a vertical linear movement.

[0033] For example, when the third 36 pinion rotates counterclockwise, the Skate 41 performs a downward vertical movement.

[0034] Therefore, by providing a linear upward movement on the skid 41, the third 36 pinion rotates clockwise transmitting the turn to the second 33 axis so through the cooperation of the second 35 receiving clutch, the roller chain 34 , the first 21 sprocket is provided a clockwise rotation movement to the servomotor 1 1. Therefore, the subject being trained overcomes the torque applied by the motor representing the load on the skate 41.

[0035] A subject wishing to exercise a set of muscles of his body must move the skate 41 vertically upward as if it were a plate or weights.

[0036] The above describes the movement of the skate 41 when the first and second brake parts 13, 14 are disengaged, that is, the solenoid is actuated. [0037] In relation now to Figures 5 and 6, it should be noted that the subject who is performing a training exercise displaces an element or bar mechanically connectable to the skate 41. For example, in the case that a bar of Exercise is associated with the skate 41, a pair of hooks with a suspension system are arranged at both ends of said bar to dampen a possible blow generated when the subject performing an exercise leaves the exercise bar in a rest position. The suspension system comprises a compression spring.

[0038] When solenoid 51 is not actuated, that is, the first and second brake parts 13, 14 are coupled, the movement of the upward skid 41 is equivalent to that described above.

[0039] When the skate 41 is moved downward, the pinion 36 rotates counterclockwise by transmitting its torque to the second shaft 33 attachable to the receiving clutch 35. The first 21 pinion is locked counterclockwise by means of the transmitter clutch 22 and the brake 13, 14; consequently, the torque supplied by the servomotor 1 1 is not transmitted to the second pinion 32 and, therefore, the receiving clutch 35 does not transmit any torque.

[0040] Skate 41 lowers without any load and the second 33 axis rotates freely in counter-clock wise. The subject who is performing a training has to overcome exclusively the torque supplied when providing an upward movement movement to the skate 41.

[0041] The torque supplied by the servomotor 1 1 is controllable by a motor controller 61 that continuously receives a position signal from the skid 41. The motor controller is localizable at one end of the second 33 axis.

[0042] Controller 61 stores a set of torque patterns internally so that a certain torque pattern associated with a particular type of training exercise can be selected. The standard torque pattern curve is shown on an audiovisual screen, see figure 4.

[0043] The controller 61 generates and supplies a signal of change or modification of the torque applied by the servo motor 1 1 depending on the value of the position signal of the second received 33 axis, of the selected training pattern and / or of the position on the pattern curve that the subject being trained is developing.

[0044] Therefore, the servomotor 1 1 supplies at all times a desired torque to a standard torque curve selected under the supervision and control of the controller 61. The selection of a standard torque curve and / or the introduction of a standard curve Torque in the controller is done through an alphanumeric keyboard and / or through a USB port, arranged for this purpose in the controller 61.
