    The invention relates to an adjustable weight training device with reactive triggering with the force allowing an agonist / antagonist musculation in contractions: concentric, isometric and eccentric. It consists of: - a reversible motorized support on which a part of the body is connected and which delivers a load of bodybuilding, - a fixed support so that another part of the body can be supported to provide an effort on the motorized support. A system for detecting the user's effort makes it possible to control the motorization of the mechanism in the opposite direction or to stop it if the user's effort becomes insufficient. The device according to the invention is particularly intended for concentric and eccentric isometric musculation transferable to training for all sports activities.

    [0001] The present invention relates to a motorized device in two reversible operating directions which reacts to a user effort by generating a force and a reverse movement, thus allowing agonist / antagonist musculation in contractions: concentric, isometric or eccentric, according to the instruction display of the force of the motorization and from any position of the motorized device. The device ceases operation as soon as the user stops his effort. Bodybuilding machines are traditionally constituted by systems configured specifically to have a functioning to work either in bodybuilding contractions: eccentric and isometric, or in bodybuilding contractions: concentric and isometric, or for some rehabilitation machines only in bodybuilding in isometric contraction. It is recalled that: if the user moves a load in a movement opposite to the direction of the load; it is in concentric contraction, - if the user maintains the load in static position, it is in contraction isometric, - if the user is driven by the load having the same movement as the direction of the load by slowing the movement of the load, it is in eccentric contraction. - an agonist / antagonist musculation alternately solicits a muscle (agonist) and its antagonist muscle, thanks to opposing movements and efforts such as: pushing-pulling, lifting-descending, pedaling in one direction-in-the-other. -the main agonist / antagonist muscles are the pairs: biceps-triceps, quadricepsischiojambiers, abdominals-lumbar ... Many experts give the eccentric contraction of strength training virtues superior to that of the concentric contraction with nevertheless some risks of ruptures muscle fibers and higher recovery times. Agonist / antagonist musculation is particularly recommended for a harmonious and balanced development of the musculature. Most weight machines work in concentric contraction, it is the user who moves the mass, but if the user relaxes his effort, the load causes the user to move; it is then an eccentric pseudo-contraction. We say pseudo because in this case the user is stronger than the load; it is only a voluntary diminution of his effort which allows the charge to train him. Few machines allow the operation in true eccentric contraction that is to say when the load exceeds the real physical possibilities of the user. In real eccentric contraction the user can only slow the movement of the load, the load must be greater than its physical capabilities. The problem in eccentric contraction resides in the return of the load in its initial position because it exceeds the concentric effort capacity of the user. Thus, it is possible to slow down the descent of a load that can not be lifted but once this load has arrived, for example at the low point, it will not be possible to raise it to the high point without outside help. Most motorized machines for eccentric contraction bodybuilding are based on principles of displacement of gravity masses but have motorized systems often pneumatic which allow to: - to relieve the user during the phase of concentric contraction during which it displaces the gravity load with an engine that tends to operate in the opposite direction to the gravity load, - or to increase the gravity load used in concentric contraction when the user works in eccentric contraction by partial motorization, coming to exert an effort in the gravitational load direction and stop its action at the end of the bodybuilding movement in eccentric contraction. The motorized weight systems in eccentric contraction without gravity mass, mainly pneumatic, do not allow the user to stop when he wants to stop his effort; the motorized movement goes to the end of its movement and it is at the end of the race that a sensor 20 or a stop can stop the movement. For safety reasons, the displacement of motorized eccentric contraction weight training systems is initially configured between an adjustable starting point and an adjustable end point to prevent the user from being trapped by a load. he can not move because he is superior to his physical abilities. Pneumatic weight training systems equipped with cylinders provide motorized displacement forces that are, by design, different in and out. Indeed, in a direction of movement, the section of the cylinder rod decreases the thrust surface reducing the force accordingly. Electric motorized systems other than treadmills are used mainly in rehabilitation by accompanying movements eccentric contraction or concentric users, but these systems favor a single direction of operation. These systems do not have two directions of operation and are not completely reversible. Thus, during a session, in the same phase, the user will not be able to reverse, abruptly, the direction of his effort to make the antagonistic muscles work on the initial effort; current systems do not adapt instantly to the user's effort. At the moment, it is necessary at best to stop the machine and configure it in the reverse movement, if it exists.
    [0002] The electric treadmills used in bodybuilding are concentric contraction weight training treadmills based on the variation of resistance to the pushing force, they do not allow weight training in eccentric contraction by not putting the user under active muscle stress generated by a motorized movement inverse to the thrust force.
    [0003] This is what OMESI RONEN presents in his invention WO 99/52601 entitled "treadmill driving traction forces and thrust" filed March 5, 1999 and published October 21, 1999. In this case, the electric motor n 'is used in brake resistant to the thrust force of the user. Displacement is caused only by the effort of the user when it is greater than the braking force of the carpet. The carpet can not put the user under muscular strain. This mat does not allow weight training in eccentric contraction or bodybuilding isometric contraction. Other motorized electrical systems are based on linear motors which resist the efforts of the user generating a musculation in concentric contractions and isometric but not eccentric. This is the invention WO 2011140432 (A1) entitled "linear motor system for a weight training device."
    [0004] The electrically powered weight training devices do not allow prolonged use in isometric contraction because it imposes a stop movement with maintenance of the driving force which causes a rise in temperature of the engine which no longer runs while consuming energy which will cause a degradation of the system. This disadvantage can be circumvented by the addition of a cooling system to DC motors, brushless motors, stepper motors, ... These industrially used systems are expensive and sophisticated control, they are not used in existing bodybuilding applications. The electric motorization from rotating engines is poorly adapted to a concentric contraction weighting in which the effort of the user is stronger than the force of the motor and imposes a direction of displacement opposite to the direction of the motor. This mode of operation implies a reversible motorization. The fact that the motor rotates in the opposite direction of the direction of its torque requires that: the motor maintains its constant torque in the rotation imposed by the effort of the user, the associated mechanical transformation of movement is reversible, the speed reduction system, often associated with the motor (geared motor), is also reversible. There are systems that have torque limiters that allow a prolonged effort without electrical heating during the blocking of the movement by the user and which are perfectly reversible, but these systems have only one operational sense for the user. The second direction of the motorization is only used for a return to the initial position.
    [0005] As part of bodybuilding, in the same sequence the user must be able to move from a phase during which its movement is imposed by the motorized driving force to a phase during which it is stronger than the motorized driving force and it reverses the movement of the motorized mechanism. The motorized weight training machine must therefore be able to pass in the same sequence of an eccentric contraction weight training phase to a concentric contraction weight training phase and vice versa. Moreover, in order to preserve the perception of the fight against a force, this reversibility of movement must be carried out with maintenance of the intensity of the motorized force. Most mechanisms allow this constancy of the motorized force; the force required for the reversal of movement is different from the initial force of the motorized system. The reversibility of displacement is accompanied by a variation in the efficiency of the motorized mechanism. In general, the force that causes the reversal of movement is greater than the initial force of the motorized system. Reversibility with conservation of mechanical or electrical efficiency is technically possible but the solutions are expensive and technologically sophisticated, leaving the traditional framework of existing motorized weight machines. Motorized weight machines, when in a cycle of operation do not allow the user to stop his effort during movement, to physically recover from his effort or change position to then resume his work weight training in the position where it stopped, with the same set point of the motorized force and this in the three modes of contraction: concentric, isometric, eccentric. In the case of a work with a vertical force in contractions: concentric, isometric or eccentric, the user produces a vertical force of lifting of a load or a force downwards in forced descent of a load directed towards the High, there is no motorized machine that allows a user to build muscle in a contraction register determined balanced weight training agonist / antagonist. Currently, a user can not exert a vertical force-lifting effort in contraction (concentric or eccentric) of the agonist muscle: the biceps, and suddenly reverse his effort by pushing the bar down with the same kind of contraction as in amount (concentric or eccentric) of the antagonist muscle: the triceps. The current motorized machines are not reversibly motorized in both directions of operation and do not stop the motorization of the load as soon as the user releases his effort of lifting or lowering. They also do not allow the activation of the engine as soon as the user again provides a significant effort, thus ensuring the complete safety of the exercise. It is therefore impossible to instantly alternate efforts upwards with efforts downwards with each time a motorized opposition force constant in one direction or the other. Agonist / antagonist musculation is therefore impossible in the same phase of vertical work.
    [0006] In the context of muscular work in contractions: concentric, isometric and eccentric, specific to the rotational movement, there is no motorized machine that stops the motorization of the load as soon as the user releases his rotational force in a direction or in the other and which engages the engine as soon as it provides again a significant effort in one direction or the other. It is therefore impossible to instantly alternate rotational forces in one direction with rotational forces in the other direction with each time a motorized opposition force constant and reversible in one direction as in the other. The agonist / antagonist musculation is therefore impossible in the same phase of work in rotation. There is no motorized device that allows a cyclist to intensively train the legs in eccentric contraction. Currently, on motorized pedaling machines, the motorized pedals do not provide a reverse torque and greater torque than the user so as to impose a reverse rotation movement to that sought by the user. A cyclist can not therefore muscling his legs in eccentric contraction in a pedaling action on a motorized weight machine. Recall that eccentric contraction is the most effective contraction in gaining strength. In the context of a horizontal muscular work in contractions: concentric, isometric and eccentric, where the user provides a horizontal force back and forth or backwards, resting on the ground, there is no motorized machine that stops the motorization of the load as soon as the user releases its thrust or pulling force and engages the engine as soon as it provides again a significant effort, thus ensuring the complete safety of the exercise. It is therefore impossible to instantly alternate efforts forward with efforts backward with each time a motorized opposition force constant in one direction or the other. Agonist / antagonist musculation is therefore impossible in the same phase of horizontal work. Currently, a complete bodybuilding session requires a lot of time because there are many muscles to work. In order to reduce the time required for weight training or fitness athletes, the traditional motorized weight systems do not allow to perform in a single motorization: an eccentric weighting, concentric and isometric, the whole body of the user by putting in muscular stress of the supports of the hands to the supports of the feet, safely and without the use of gravitational loads. All bodybuilding machines for upper body or upper body and lower body bodybuilding are organized around the movement of a force acting on the upper body, mainly on the arms or shoulders. The load moves towards the user, thanks to its supports in connection with the ground, the user exerts an effort on the load; either he contains it and he does not move, either he pushes it back and advances on its supports, or he can not push it back and he backs on its supports. This is the case of the weight machines used by rugby players, to practice the practice of melee. Currently, this type of motorized drive machines does not allow the user to have an extended displacement on its supports; movements are limited to the stroke of motorized mechanisms acting on the upper body.
    [0007] There is no reversible motorized muscular machine with two directions of movement, organized around the motorized movement of the user's ground support towards a fixed support of the upper body. Such a system would reduce congestion while maintaining the same muscle demands and allow a total muscle stress. In order to make the bodybuilding action more complex in order to work a maximum of muscles in a minimum of time, the current motorized machines do not allow the technological associations of different motorized weight systems. A technological association of different motorized systems would allow the assembly of complex weight machines justified by a gain in overall bodybuilding time. For example, from a motorized machine with horizontal displacement and a motorized machine with vertical displacement, both possessing a homogeneous and compatible technology, it would be a question of constituting a complex machine of motorized musculation allowing to work at the same time horizontally and vertically in the three modes of contraction: concentric, isometric and eccentric. The motorized weight machines do not deliver a progressive force to avoid muscle or joint injuries of the user mainly in the case of an eccentric contraction weight training with motor load greater than the physical capabilities of the user. Thus, in summary, the analysis of previous techniques shows that there is no motorized weight training machine allowing, in the same exercise, alternating work of agonist and antagonist muscles. This kind of exercise would allow balanced muscle development of agonist / antagonist muscle sets such as: biceps-triceps, quadriceps-hamstrings, abdominal-lumbar. Ideally, this motorized bodybuilding machine could allow this agonist / antagonist musculation, in the three modes of contraction: concentric, isometric and eccentric. The device according to the invention overcomes all these disadvantages. Whatever the direction of use, horizontal, vertical or rotary, it comprises, in fact, a motorized mechanism with two reversible directions of operation each having a direction, a speed, a force of advance and a fixed support. The user leans on the motorized mechanism with a part of the body, the other part of the body is in connection with the fixed resistant support allowing the user to take a support to exert a force opposite to the motorized force.
    [0008] As soon as the user exerts a force on the motorized mechanism in one of the two directions of movement of this mechanism, the motorization generates a force of direction opposite to the direction of the effort of the user and seeks to move in the direction of the strength of the mechanism. The initial effort of the user can be made from any position of the motorized mechanism and in any direction. The motorized mechanism will react in opposition to this initial effort and stop exerting force and moving as soon as the user relaxes his effort. The actual displacement of the motorized mechanism depends on the effort of the user: - if the effort of the user is less than the motorized force the mechanism will move in the direction of the motorized force; the user works in eccentric contraction, -if the user's effort is equal to the motorized force, the mechanism will not be able to move but will continue to exert its force; the user works in isometric contraction, -if the user's effort is greater than the motorized force, the reversibility of the motorized mechanism will allow a displacement opposite to the direction of the motorized force; the user works in concentric contraction. In the three previous cases, the use of an appropriate system based on electromagnetic coupling transmits a constant torque to the mechanism and is maintained regardless of the direction of displacement imposed or suffered by the user. This transmitted torque comes partially or completely from the engine torque, depending on the electromagnetic coupling setting.
    [0009] To enable this operation, the device must have a system for detecting the direction of the user's effort so that the direction of the force of the motorization and the resulting displacement can be controlled accordingly. The intensity of the force of the motorized mechanism is easily adjustable via the electromagnetic coupling. This intensity is a set value that the electromagnetic coupling retains during the operating cycle regardless of the phases of use; concentric contraction, isometric contraction or eccentric contraction. To allow safe operation, it is necessary to implement minimum forces of tripping and stopping the motorized mechanism, to prevent a child can start the system or a tired user is blocked under the motorized load . The device therefore comprises a system that allows the user to detect the intensity of the minimum effort to control: - the stopping of the motorized mechanism as soon as the user provides a force of an intensity lower than this value of safety, - the setting in motion of the motorized mechanism as soon as the user provides a force of an intensity higher than this security value.
    [0010] A system allows to regulate this minimum safety effort. A traditional automation (programmable logic controller, electronic card, cable technology, ...) manages the system but nevertheless has some specificities: -a system for viewing the user's effort time, -a system for visualizing the system. the posture of the user during the effort, a progressivity in the application of the set force. - a speed adjustment of the displacement. Thus, the motorized mechanism according to the invention, allows to have in the same exercise the ability to work the agonist and antagonist muscles in contractions: concentric, isometric and eccentric without changing the motorized machine or configuration or adjustment of this machine motorized. In order to meet the different needs of users, from the same motorized mechanism according to the invention, the device declines mainly in three structural positions: horizontal, vertical and rotation. The motorizations: horizontal and vertical, can be combined and create a complex machine of bodybuilding allowing to reduce the time devoted to the exercises of musculation. The horizontal configuration comprises: - The reversible motorized mechanism, as described above, which drives a treadmill in the directions, front and rear, on which the user can make a forward and backward effort, a support support fixed horizontally, consisting of a horizontal cross linked to the motorized mechanism by two vertical elements of adjustable height on which the user bears with the top of his body. For example, if the user pushes the belt backwards, the system reacts and moves the belt forward by exerting a force equal to the set value, if the user pushes the belt forward, the The system reacts and moves the belt backwards by exerting a force equal to the set value. If the user pushes less than the set value the moving of the mat will put the user into eccentric contraction. If the user pushes as much as the set value the movement of the mat will be zero but the force will be present, opposed to the effort and constant. The user will be in isometric contraction. If the user pushes more than the set value the movement of the carpet will be in the direction of the effort of the user; it will be in concentric contraction. If the user stops pushing the mat stops. If the user alternates backward thrust with a forward thrust he is in agonist / antagonist bodybuilding.
    [0011] The vertical configuration comprises: - a reversible motorized mechanism as indicated above which drives two slides connected by a sliding horizontal crossbar in vertical supports in the up and down directions, on which the user can perform with the upper body an effort of ascent and descent, a low support support constituted by a fixed horizontal support, linked to the vertical motorized mechanism on which the user bears with the lower part of his body. Thus: - if the user exerts a force on the bar upwards, the system reacts and sets the bar downwards by delivering a force equal to the set value, - if the user exerts a force on the bar downwards, the system reacts and moves upwards, delivering a force equal to the set value. if the user exerts a force less than the set value, the displacement of the bar will put the user in an eccentric contraction. -If the user pushes as much as the set value the movement of the bar will be zero but the force will be constant. The user will be in isometric contraction. if the user pushes more than the set value, the displacement of the bar will be in the direction of the effort of the user; it will be in concentric contraction. if the user stops exerting an effort on the bar the system stops. if the user alternates a bar lift with a bar descent; he is in agonist / antagonist bodybuilding. The rotary configuration comprises: - a reversible motorized mechanism as indicated above which drives a lever or pedals in rotation about the motor axis which rotates in both directions, on which the user can perform with the arms or with the legs an effort rotation, -a support support constituted by a fixed support linked to the motorized mechanism on which the user bears with another part of his body. For example, if the user turns the force lever in one direction, the system reacts and turns the force lever in the opposite direction, exerting a torque equal to the set value.
    [0012] If the user exerts a force lower than the set value the rotation of the lever will put the user in eccentric contraction, his support will move driven by the movement of the lever. If the user pushes as much as the set value the movement of the lever will be zero but the torque will be constant. The user will be in isometric contraction. If the user pushes more than the set value the movement of the lever will be in the direction of the effort of the user; it will be in concentric contraction.
    [0013] If the user stops exerting a force on the lever, the system stops. If the user alternates a rotational effort in one direction with a rotational effort in the other direction; he is in agonist / antagonist bodybuilding. The rotary device according to the invention of the motorized mechanism allows a cyclist to perform a weight training legs eccentric contraction. A motorized pedals according to the invention can provide a torque greater than the torque of the user and impose a reverse rotation movement to that sought by the user. This will be a real eccentric contraction very effective, which will allow the user to gain muscle power. If the user provides a torque equal to the pedal operator's setting, the user will be in isometric contraction; the exercise will be static but also very effective in gaining muscle power. If the user provides a torque greater than the adjustment of the pedal operator, the user will be in concentric contraction; we will then find the existing principles of motorized exercise bikes.
    [0014] A complex machine may be constituted by a motorized machine with horizontal structure as described above and a motorized machine with vertical structure as described above. The vertical motorized structure being mounted in place of the vertical fixed support of the horizontal motorized machine. Thus, we built a complex machine with two motorized systems of the same composition and homogeneous control.
    [0015] The attached drawings illustrate the invention: FIG. 1 represents the device of the invention with motorized mechanism in the horizontal plane with a front movement of the mat that reacts and opposes the rearward force of the user on the carpet. Figure 2 shows the device of the invention with motorized mechanism in the horizontal plane with a rearward movement of the carpet that reacts and opposes the forward effort of the user on the carpet. Figure 3 shows the construction of the horizontal motorized system and more particularly the drive of the treadmill supporting the efforts of the user. FIG. 4 shows the device of the invention with motorized mechanism in the vertical plane with a movement of the motorized slideways that react and oppose the downward force of the user on the crossmember. FIG. 5 represents the device of the invention with motorized mechanism in the vertical plane with a downward movement of the motorized slides that react and oppose the user's upward force on the crossmember.
    [0016] Figure 6 shows the construction of the vertical version of the device of the invention.
    [0017] Figure 7 shows the device of the invention with motorized mechanism in rotation with a rotational movement of the lever which reacts and opposes the user's rotational force of rotation on the lever. Figure 8 shows the device of the invention with motorized mechanism in rotation with a rotational movement of the lever which reacts and opposes the user's anti-clockwise rotation force on the lever. Figure 9 shows a combination of the horizontal motorized mechanism with the vertical motorized mechanism. Figure 10 shows a possible application of the combination of the horizontal motorized system with the vertical motorized system. This application concerns the game of rugby in its thrust phase in melee. With reference to FIGS. 1, 2 and 3, the device applied to a horizontal motorization comprises: a horizontally motorized low support consisting of a rotating carpet (1) on which the user bears (2) with his feet, fixed high support (3) constituted by a bar on which the user bears with his hands. The motorization of the belt (1) is achieved by an electric geared motor (5) of 550 watts with two directions of rotation. This geared motor has a torque of 80 Nm with an output speed of 10 rpm. The output shaft of the gearmotor is connected in rotation to a clutch (4) to magnetic powder of transmissible torque adjustable by electrical control (8) 0-10 volts with a maximum torque equal to 64Nm. The output shaft of the clutch is coupled to a general drive shaft which will transmit torque and operating speed to the belt (1). The magnetic powder clutch (4) provides a constant torque proportional to the intensity of a magnetization current of the powder. The higher the current, the greater the magnetization and the more the clutch can transmit torque. This current is adjusted using a control module managed by a 0-10 volt potentiometer (8) located on the control panel (9) available to the user. The torque transmitted by the powder clutch is perfectly reversible; the reversal of direction requires no additional effort and the programmed torque is maintained regardless of the direction of rotation. When the effort of the user on the belt generates a torque greater than the value of the torque provided by the clutch, the clutch output movement is reversed but the setpoint torque and its direction are maintained. the clutch resists the concentric contraction of the user; the clutch torque behaves like a constant brake.
    [0018] When the user's effort on the belt generates a torque equal to the value of the torque provided by the clutch, the output movement of the clutch is zero but the setpoint torque and its direction are maintained. the clutch resists the isometric movement of the user; the clutch torque behaves like a fixed load equal to the effort of the user.
    [0019] When the effort of the user on the belt generates a torque lower than the value of the torque provided by the clutch, the clutch output movement imposes its direction and its value on the belt .The clutch torque is motor, the low supports of the user move in the opposite direction of the direction of his effort; the user is in the phase of bodybuilding contraction eccentric, under the muscular stress he will be forced to move his feet.
    [0020] This geared motor (5) is controlled by an electronic variator to adjust the base speed of the carpet which is equal to 10 cm / s. This frequency variator also makes it possible to program a progressive rise in the intensity of the driving force as well as the progressiveness of the setting in motion. The motorized weight-training mechanism providing horizontal forward or backward movements, as previously described, drives a specific treadmill (1) from a general drive shaft (11). On the general transmission shaft (11), 2 pinions (12) freewheel are mounted in opposition. According to the direction of rotation that is controlled by the general transmission shaft, the transmission of the motorization will be either to the "front" shaft (13) or to the "rear" shaft (14). Thus, when the carpet must unfold forwardly are the gears of the "front" shaft (13) which are driven, the gears of the "rear" shaft (14) remaining free and when the carpet must be unrolling backwards are the gears of the "rear" shaft (14) which are driven, the gears of the "front" shaft (13) remaining free. A torque retention system provided by the magnetic powder clutch transmits an adjustable torque from 0 to 64 Nm constant whatever the movement of the belt.
    [0021] The carpet consists of rigid boards (10) 80 cm long, 12.5 cm wide and 3 cm thick. These boards roll on a bearing path (15) linked to the frame. This ball raceway allows a consequent reduction in the mechanical friction of the boards on the low support. These boards are guided laterally by lateral guides, this guidance allows a non-focused effort of the user. The driving of the carpet of boards is carried out by a system of pinions (16), chains of transmission (17), chains of fixation of the boards (18) and free wheels (12) allowing the upper part of the carpet of always be stretched regardless of the direction of rotation of the motor. The carpet assembly (1) thus formed allows the user to be able to push with his feet by exerting forward or backward thrust forces of up to 250 daN. The high support consists of a simple horizontal force bar (3) connected to the frame of the lower support (20) by vertical uprights (21). These uprights have a hinge (22) for detecting the direction of the forward or backward force on the carpet by a magnetic position sensor (23) indicating that the user creates a rearward force on the carpet by pushing on the stress bar and a magnetic sensor (24) indicating that the user creates a forward effort on the mat by pulling on the stress bar. Compression springs (28) in the same zone are calibrated to a minimum safety value and require the user to compress them to allow the sensors to trigger movement. If the force is less than the safety value, these same springs bring the high support back to the middle position thereby stopping the movement of the belt by deactivation of the position sensors. The traditional control cabinet (25) comprises an industrial programmable logic controller or an electronic card that manages the operating cycle, safety and management of power energy through the variable speed drives associated with the motors. The dialog member with the user allows: -the adjustment of the force of the belt (26), -the speed of movement of the motorization (27), -the visualization of the effort time. An auxiliary element consists of a webcam type camera that allows the user to see his posture effort on a screen and correct it. With reference to FIGS. 4, 5 and 6, the device applied to a vertical motorization comprises: a high support constituted by a force bar connected to the frame by two motorized slides (31) vertically, guided in vertical uprights ( 32) fixed on the low support. a fixed low support (33) constituted by a flat support on which the user bears with his feet. The motorization of the vertical slides is achieved by an electric geared motor (34) of 90 watts with two directions of rotation. This geared motor has a torque of 20 Nm with an output speed of 10 rpm. The output shaft (37) of the gearmotor is rotatably connected to a clutch (35) magnetic powder torque transmissible adjustable 0-10 volts electrical control with a maximum torque equal to 12Nm. The output shaft of the clutch is coupled to a general transmission shaft (38) which will transmit the torque and operating speed to the vertical slides (31).
    [0022] The clutch (35) magnetic powder provides a constant torque proportional to the intensity of a magnetization current of the powder. The higher the current, the greater the magnetization and the more the clutch can transmit a large torque. This current is adjusted using a control module managed by a 0-10 volt potentiometer (8) located on the control panel (25) available to the user.
    [0023] The torque transmitted by the clutch (35) powder is perfectly reversible; the reversal of direction requires no additional effort and the programmed torque is maintained regardless of the direction of rotation. When the effort of the user on the bar (30) generates a torque greater than the value of the torque provided by the clutch, the clutch output movement is reversed but the setpoint torque and its direction are maintained. The clutch torque resists the concentric contraction movement of the user; the clutch torque behaves like a constant brake. When the effort of the user on the bar (30) generates a torque equal to the value of the torque provided by the clutch, the clutch output movement is zero but the setpoint torque and its direction are maintained. The torque of the clutch resists the movement in isometric contraction of the user; the clutch torque behaves like a fixed resistance equal to the effort of the user. When the effort of the user on the bar (30) generates a torque lower than the value of the torque provided by the clutch (35), the clutch output movement imposes its upward or downward direction and its force to the bar (30) .The clutch torque creates the displacement, the high supports of the user move in the opposite direction of the direction of his effort; the user is in eccentric bodybuilding phase, under the muscular stress he will be forced to raise or lower his arms. This geared motor is controlled by an electronic variator to adjust the base speed of the carpet which is equal to 3 cm / s.
    [0024] This frequency variator also makes it possible to program a progressive rise in the intensity of the driving force as well as the progressiveness of the setting in motion. The motorized weight-training mechanism providing upward or downward vertical movements, as previously described, drives guide rails in a specific vertical support from a general drive shaft.
    [0025] The movement is transmitted by a rack and pinion system: the pinion (43) is fixed on the fixed vertical upright (32) and the rack (42) on the mobile vertical upright (31). The connection between the output of the clutch (35) and the pinion (43) is effected by a chain transmission (36) of a small pinion of 20 teeth to a pinion of 40 teeth, this transmission will reduce the speed and increase the torque.
    [0026] Each vertical upright is composed of a fixed part (32) in connection with the frame and a movable part (31) guided in vertical translation by bearings (44) fixed on the fixed upright (32). The force bar (30) is connected to the movable portion via a mechanism (39) for detecting the direction of effort of the user and to verify that the minimum safety effort is reached. This detection is effected by means of a magnetic position sensor (40) indicating that the user creates an upward force on the force bar (30) and a magnetic sensor (41) indicating that the user creates a downward effort on the stress bar (30). Compression springs located in the same zone are calibrated to a minimum safety value and require the user to compress them to allow the sensors to trigger the movement. If the force is less than the safety value, these same springs bring the bar (30) to the middle position thereby stopping the movement of the slides by deactivation of the position sensors. The traditional control cabinet (25) comprises an industrial programmable logic controller or an electronic card that manages the operating cycle, safety and management of power energy through the variable speed drives associated with the motors. The dialog member with the user allows: the adjustment of the vertical force (8), the speed of movement of the motorization (26), the visualization of the effort time. Referring to Figures 7 and 8, the device applied to a rotary actuator comprises: - a reversible motorized support (53) which rotates in both directions a force lever (51) on which the user exerts a rotational force . an auxiliary support (52) fixed which the user bears. The motorization of the force lever (51) is performed by an electric geared motor (53) of 550 watts with two directions of rotation. This geared motor has a torque of 80 Nm with an output speed of 10 rpm. The output shaft of the geared motor (54) is rotatably connected to a magnetic powder clutch (56) of transmissible torque adjustable by electrical control (8) 0-10 volts with a maximum torque of 64Nm. The output shaft of the clutch (55) is coupled to a general drive shaft which will transmit torque and operating speed to the force lever (51). The magnetic powder clutch (56) provides a constant torque proportional to the intensity of a magnetization current of the powder. The higher the current, the greater the magnetization and the more the clutch can transmit a large torque. This current is adjusted using a control module managed by a 0-10 volt potentiometer (8) located on the control panel (9) available to the user. The torque transmitted by the powder clutch is perfectly reversible; the reversal of direction requires no additional effort and the programmed torque is maintained regardless of the direction of rotation. When the effort of the user on the force lever (51) generates a torque greater than the value of the torque provided by the clutch, the clutch output movement is reversed but the target torque and its direction are The torque of the clutch resists the concentric movement of the user; the clutch torque behaves like a constant brake.
    [0027] When the effort of the user on the force lever (51) generates a torque equal to the value of the torque provided by the clutch, the clutch output movement is zero but the target torque and its direction are The torque of the clutch resists the user's isometric movement; the clutch torque behaves like a fixed resistance equal to the effort of the user. When the effort of the user on the lever (51) generates a torque lower than the value of the torque provided by the clutch, the clutch output movement imposes its direction and its value on the lever ( 51) .The couple of the clutch creates the displacement, the support of the user on the lever (51) move in the opposite direction of the direction of his effort; the user is in the eccentric bodybuilding phase, under the muscular stress he will be forced to rotate his supports by accompanying the movement of the force lever (51). This geared motor is controlled by an electronic variator to adjust the basic speed of the lever which is equal to 10 rpm. This frequency variator also makes it possible to program a progressive rise in the intensity of the driving force as well as the progressiveness of the setting in motion. The motorized body-building mechanism providing rotational movements in one direction or the other, as previously described, drives a force lever rotated by the general transmission shaft (). The transmission of the movement is carried out directly on the general transmission shaft.
    [0028] The force lever contains a mechanism to detect the direction of the user's effort and to verify that the minimum safety effort is reached. This detection is carried out by means of a strain gauge (56) indicating that the user creates a force in one direction on the lever and a strain gauge (57) indicating that the user creates an effort in the other direction on the lever of force. A rotating joint (55) retrieves information on the direction of the effort of the user and on a threshold of minimum intensity of this effort. This intensity threshold will require the stopping of the motorized mechanism if it is not reached or the start of the motorized mechanism if it is reached and exceeded. With reference to FIG. 9, the device applied to combinations of motorized weight-training mechanisms comprises: the horizontally powered motor-driven mechanism moving a treadmill as illustrated in FIG. 1, FIG. 2, FIG. 3. A vertically powered mechanism of FIG. bodybuilding displacing a horizontal force bar as illustrated in FIG. 4, FIG. 5, FIG. 6-a combination of the two motorized mechanism control systems. The arrangement of the two devices is organized as follows: the support plate (33) of the vertical device is removed, the articulation (22), the zone (6) with the detection system (23) (28) and (24) of the horizontal device are transferred on the upright 32 of the vertical system, - the control part is managed with traditional automation, which is only the juxtaposition of the two control systems of the horizontal device and the vertical device. The operation takes the characteristics of both horizontal and vertical devices. Initially, the user is supported with his feet on the low support and in connection with the top of his body on the high support. The horizontal motorization relates to the front and rear horizontal moving belt, the bar (30) being fixed in the horizontal direction. The vertical motorization relates to the bar (30) with vertical displacement of rise or fall. The two modes of horizontal and vertical stresses can work simultaneously or one without the other. The value of the horizontal force of the belt (1) and the value of the vertical force of the bar (30) are adjustable on a control panel (9). The value of the horizontal speed of the low support and the value of the vertical speed of the high support are adjustable on a control console.
    [0029] It is the effort of the user forwards or backwards on the belt (1) which triggers the movement of the belt (1) with the force set at the set point. It is the user's effort of raising or lowering on the bar (30) which triggers the setting in motion of the bar (30) with the force set to the set value. These efforts are only taken into account if they exceed a minimum security value that prevents children from using the system. If during use the user does not provide the minimum safety effort the corresponding movement stops, thus allowing the user to stop the constraint when he wishes. For the motorization of the carpet (1): - if the user produces a minimum force in a rear direction on carpet, the carpet will advance and put the user in physical constraint between the carpet (1) and the bar (30), - if the user produces a minimum force in the forward direction on the mat (1), the mat (1) will back down and put the user in physical constraint between the mat (1) and the bar (30), -if the user provides an equal and opposite force to the strength of the belt (1), the belt (1) will be blocked in its advance but the strength of the belt (1) will remain equal to the set value and continue to apply on the user, the user will be in isometric weight training, -if the user provides a greater effort and opposite to the strength of the mat (1), the mat (1) will reverse its direction of movement but the driving force of the mat (1) will remain equal to the set point and will continue to apply on the user in the original direction, the user will be in bodybuilding concentric, -if the user provides a lower force and opposite to the strength of the carpet (1), the carpet (1) will continue its direction of movement forcing the user to move its supports on the carpet (1) to find a new position of effort on the mat (1), the user will be in eccentric weight training. For the motorization of the bar (30): - if the user produces a minimum climbing effort on the bar (30), the bar (30) will descend and put the user in physical constraint between the mat (1) and the bar (30), - if the user produces a minimum descent force on the bar (30), the bar (30) will rise and put the user in physical constraint, -if the user provides an equal and opposite effort the bar (30) will be blocked in its advance but the force of the bar (30) will remain equal to the set value and continue to apply to the user, the user will be in isometric weight training, -if the user provides a greater force and opposite to the force the bar (30), the bar (30) will reverse its direction of movement but the driving force the bar (30) will remain equal to the set value and will continue to apply on the user in the original sense, the user will be in concentric musculation, -if the user provides a lower and opposite force force the bar (30), the bar (30) will continue its direction of movement forcing the user's upper supports to follow the movement of the bar (30), the user will in eccentric bodybuilding. In both cases, the user will be able during the same exercise to move alternately from an eccentric thrust movement on the belt (1) towards the rear to an eccentric movement of forward thrust, a concentric movement of pushing the belt (1) backwards to an eccentric forward thrust movement, an eccentric bar climb movement (30) to an eccentric downward movement and a concentric bar climb movement (30) to a concentric movement of descent. Realizing a real session of agonist / antagonist musculation. With reference to FIG. 10 The combination of the systems defined according to the invention makes it possible to create a push-training machine in melee specific to the rugby game.
    [0030] This system consists of: the horizontal motorized mechanism according to the invention, as previously described and illustrated by FIGS. 1, 2 and 3, of the vertical motorized mechanism according to the invention, as previously described and illustrated by FIGS. and 6. - a constructive organization as previously described and illustrated in Figure 9. A quilted yoke (60) is attached to the force bar (30) which is animated with a vertical movement. The player pushes backwards on the mat (1), the mat reacts and exerts a force forward putting the player into muscular strain. If the player provides a greater effort than the mat, the mat moves backwards; the movement of the player corresponds to that of a player who advances. If the player provides less effort than the mat, the mat moves forward; the movement of the player corresponds to that of a player who recoils. If with the upper body, the player exerts an upward effort, the yoke will force down. If with the upper body, the player exerts a downward effort, the yoke will force upward.
    [0031] The resulting displacement of this player-versus-motorized fight will be the movement imposed by the player if he is stronger than the machine or moving the machine if he is stronger than the player. The fight ends as soon as the player relaxes his effort; the motorized machine stops its movement. The device according to the invention is particularly intended for the training of athletes: - sports halls by allowing users: - to solicit in a short time a maximum of muscle groups, - to work safely in eccentric weight training that corresponds to the case where the loads cause the movements by putting the user in resistance. This is the most effective bodybuilding mode but the fact that the load dominates the user makes it dangerous with traditional devices. The device according to the invention allows the blocking of the load as soon as the user disengages. -to work in the same exercise, without changing the supports, the agonist and antagonist muscles alternately following the two directions of motorization in the three modes of contraction: isometric, concentric and eccentric, thus ensuring a balanced bodybuilding. - to rugby clubs by climbing on the bar (30) a yoke of rugby. Such a system will allow to train individually to thrust in melee. After disassembly of the yoke, the system will find a configuration for use of complex bodybuilding. - cyclists who want to gain pedaling power by working on a pedal that allows eccentric muscular contractions. The pedal motor tries to turn the pedals in the opposite direction to that of the user.5
