Definitions

  • the invention relates to an exercise device intended in particular for rehabilitation, training and investigation of neuro-muscular function.
  • the present invention provides an improved exercise machine.
  • the apparatus of the invention comprises a fixed frame, a working member intended to be connected to the subject to be exercised, a driving member, a transmission device mounted between the driving member and the working member, and means for adjusting, controlling and quantifying the force and / or the displacement of the working member as a function of determined parameters.
  • this transmission device comprises, mounted in parallel between the driving member and the working member, on the one hand a force coupler whose transmitted torque is adjustable, and on the other hand share a one-way drive means, which connects the working member to the motor member when the ratio of their speeds in absolute value exceeds a predetermined threshold.
  • a frame 1 supports a motor 10, the output shaft of which is connected to a reduction gear. 11 irreversible.
  • the motor and the gearbox are for example the MELY-CLERELY 0/3000 rpm 400 watts models.
  • the output shaft 20 of the reduction gear 11 is supported at its other end by a bearing 12. In the intermediate part, it is provided with a notched crown of fairly large diameter 21. At its other end, it is provided with a second notched crown of smaller diameter 30.
  • This crown 23 is connected to the large crown 21 by a first transmission chain 22.
  • a rope-holding drum 50 is mounted rotating on the shaft 4.
  • the rope 5 comes out between two rope guide shafts 51 and 52, to come to its free end to form a loop 55 on which is mounted for example a handle 56, as regards the musculature of the arms. Any other suitable means of gripping and / or fixing will be used for other parts of the body, such as the legs.
  • the right flange of the drum 50 is integral with the outer ring of an electromagnetic powder clutch 35.
  • This clutch is for example of the MEROBEL EAT 120 type.
  • the internal crown 35bis of the clutch 35 is mounted integral with the shaft 4.
  • the so-called “eccentric” chain of motion made up of the elements 10, 11, 21, 22, 23, 4, 35bis, transmits its angular speed N 2 to the rope-holding drum 50 when the inductor winding of the clutch 35 is put under pressure.
  • This chain therefore tends to wind the rope on the drum and to drive the patient's arm by the handle 56; if the operator resists too strongly, the clutch "slips", and there is relative movement between the crowns 35 and 35bis, but with transmission of a calibrated force on the rope in the direction of rewinding.
  • the tared force depends on the adjustment of the intensity of the excitation current which flows through the clutch inductor 35.
  • the outer ring of the 1 "clutch 35 is also connected to a latching system 36 (or freewheel), which receives its movement from a notched ring 33.
  • the notched crown 33 is driven in the opposite direction to the movement imparted to the shaft 4 by the chain 22.
  • This drive in the opposite direction is obtained by a second chain 32, which is wound on the notched crown 30 already mentioned, on two return crowns 34 and 35, to finally come to drive the crown 33 upside down.
  • N 1 the speed of rotation of the shaft 20
  • N 2 the speed printed by the belt 22 to the shaft 4 in a first direction
  • N 3 the lower speed that the belt 32 can print to the drum in the opposite direction, that is to say in the direction of the needles of a watch.
  • the clockwise direction corresponds to the unwinding of the rope 5 on the drum 50
  • the anticlockwise direction corresponds to the winding of the rope 5 from the drum 50.
  • the latching 36 does not transmit any force to the external crown 35 and to the drum 50 which is linked to it, as long as the action developed by the patient who pulls on the rope by the handle 56 does not tend to impart to him the same speed direction but greater than the speed imposed on the latching 36 by the so-called "concentric" chain of motion constituted by the elements 10, 11, 20, 30, 32, 33.36.
  • the maximum linear speed of unwinding of the rope is preset, independently of the intensity of the forces exerted by a servo-control which is exerted on the motor and reduction unit 10 and 11, as will be seen below.
  • the resistance to the unwinding of the rope is then directly controlled by the active traction force that the patient develops.
  • this function can be called muscular training in the "concentric dynamic slave mode”.
  • the apparatus according to the invention also makes it possible to develop static muscular contractions, as well as eccentric dynamic contractions obtained by the so-called eccentric chain mentioned above. As will be seen below, these three modes of exercise can be linked in a predetermined manner.
  • the two eccentric drive chains 10, 11, 21, 22, 23, 4, 35bis, and concentric drive 10, 11, 20, 30, 32, 33, 36 have so far a common drive source 10, 11.
  • It includes the device (s) for effort and / or position detector (s) and the transmitter transmitting without link the signals from this (these) detector (s) to the receiver-iecoder located in the block vs.
  • Block C is the mobile unit, made available to the subject to be trained and specialized personnel monitoring or programming the exercises of one or more subjects.
  • It includes training cycle programming devices; visualization functions for cycled operations and the magnitudes of the efforts or positions actually developed or achieved; fault or performance reporting and counting systems; the elements producing the output signals intended for recording (for example on plotter x (t) or xy); the elements making it possible to program the duration of the functions in the chosen cycle; operating systems either manual or automatic, programmable in time and / or programmable according to the delivered or rewound length of the wire.
  • a fixed link by an interconnection cable is established between blocks A and C to convey electrical power and adjustment signals.
  • FIG. 3 (and / or 3bis), illustrating a certain number of sub-blocks of an electrical diagram in principle.
  • the sub-blocks A are intended to be part of the fixed wall frame of FIG. 2, constituting a working unit A.
  • the block B is a sensor circuit which is physically located between the working unit A and the handle 56 for example held by the patient.
  • the sub-blocks C are part of a mobile unit made available to the trained subject, as well as to that of the specialized personnel who direct the exercise of one or more patients.
  • FIGS. 1A, 1B and 1C It is the block A which brings together the mechanical elements illustrated in FIGS. 1A, 1B and 1C.
  • an electronic circuit is provided consisting of five separate plates.
  • the board Al defines the general supply circuit from the sector. It consists of a button with two general commissioning states, capable of cutting the phase and the neutral.
  • This pusher noted 101 is associated with a control lamp 102. Downstream of the switch thus formed is provided a low voltage safety supply with high insulation 105.
  • This supply supplies the various currents in particular at six volts necessary for the electronic circuits. It also feeds by self-excitation a relay 103, capable of cutting the circuit of the general supply by its movable contacts 103A and 103B.
  • the electrical circuit for controlling the relay 103 passes through a manual switch 104 with a push button in a state made available to the patient in the event of difficulties, the patient can therefore at any time interrupt the operation of the device.
  • an automatic detector such as a circuit breaker (not shown) in the input of the general circuit at 220 volts 50 Hertz.
  • a block 110 serving for the supply of the mobile unit C, of which it therefore constitutes the first module C1.
  • a set of wires connecting with a ground or earth therefore goes to the mobile unit C from the housing 110.
  • a plate A2a again appears the motor 10 and its reduction gear 11.
  • the general alternating supply excites a variator 121, which is connected to the terminals of the control and servo circuit 122 of the motor 10.
  • the excitation of the motor is provided by a block 123, in a manner known per se.
  • the block J22 includes a potentiometric unit 125, which defines the maximum speed of the motor as a function of the exercise which the patient must perform.
  • the potentiometer 125 has a value of 10 KQ
  • the work unit includes a relay plate C2.
  • this plate C2 will provide on four wires an indication of current representative of a minimum rewinding force or torque. This information is applied to a current generator 140, which receives the general electrical supply, and controls the powder clutch 35.
  • the current generator is the MEROBEL type 1 model.
  • a potentiometer 145 allows the minimum rewinding torque of the rope to be defined.
  • the pitcher B It is an autonomous unit provided with a battery 150, which supplies a transmitter circuit 151, operating for example at 27.2 MHz.
  • a sensor 155 which is for example of the strain gauge type, is fixed to a deformable metal plate. This plate can be incorporated into the wire guide rollers 51 and 52, when these support most of the force transmitted by the rope. As a variant, the wafer could be directly incorporated into the cable itself, in the vicinity of its end 55.
  • a multi-channel transmitter can be provided, when several parameters are to be monitored simultaneously and / or sequentially.
  • the mobile unit C constitutes an autonomous control and monitoring desk allowing an experienced operator to control all the functions or exercises that the patient will undergo and perform, who will be informed by this mobile unit of the effectiveness and respect for scheduled activity
  • a receiver 160 tuned to the same frequency as the transmitter 151 receives the signal therefrom.
  • the receiver 160 is provided with an output level adjustment by a potentiometer 161. It is supplied like the other elements of this box C by the supply 110 already mentioned.
  • the signal supplied by the receiver 160 is applied to a force display circuit, denoted 163.
  • This display circuit can comprise different types of displays, in particular a row of light-emitting diodes producing a chain of light points the length of which varies with the magnitude of the effort developed.
  • a galvanometer can be used as a variant.
  • the output of this case 163 can be connected to an adapter 165 intended to be in turn connected to a recorder by output lines S1 and S2.
  • the recorder is not shown.
  • This time-programmable sequence can be replaced by a programmable sequence depending on the length of the unwound rope (or the length of rewound rope).
  • In 171 are illustrated the electroluminescent displays indicating the current function.
  • In 172 are illustrated the adjustment potentiometers which form part of the abovementioned RC circuits, and allowing the adjustment of the duration of activation of each flip-flop, for example from 0 to 20 seconds.
  • the device (A) can be used or not, in a pulley therapy cage; the rope 5 allows either analytical or functional use, which combines the mobility of several body segments in several planes.
  • the programmable speed of unwinding of the rope makes it possible to execute more or less rapid, reproducible activities, depending on the objective sought.
  • the enslavement of the resistance, to the developed tensile force makes it possible to train the subject always to the maximum of his possibilities, regardless of the position adopted for a given speed. In addition, this enslavement cancels the painful sector which sometimes appears during the lifting of direct loads.
  • the programmable device allows the subject to be trained specifically in cycles associating different muscular contractions: concentric slave, static and / or eccentric.
  • the detection of the developed force, reflected in a visualization system provides a bio-feedback technique, useful for the subject, to control his activities.
  • this device by virtue of the programmable aspect of the cable rewinding efforts and of the switchable sequences, can be used for the purposes of joint traction and of osteo-articular postures.
