Definitions

  • the invention relates to a device for controlling and regulating a physical exercise apparatus as well as to the apparatus provided with such a device, whether it is a muscular and / or physiotherapy apparatus. .
  • the piston divides the cylinder into two separate chambers, of variable volumes and filled with this hydraulic fluid.
  • the two chambers of variable volumes are interconnected by a circuit allowing the fluid to go alternately from one compartment to the other, passing at least in one direction of movement, by a regulating member such as a choke, preferably adjustable.
  • the devices provide a second circuit controlled by a second regulating member, the distribution to one or the other of the circuits according to the direction of movement is then ensured by non-return members.
  • FR-A-2,162,715 a device which makes it possible more particularly to produce rhythmic elongations on a member to be re-educated.
  • This device mainly comprises a single-acting cylinder, the movable part of which is connected to the member to be treated.
  • the exhaust is caused by the action of a return spring on the piston while the intake and the exhaust are controlled by solenoid valves controlled by a cyclic control device. .
  • One result which the invention aims to obtain is a physical exercise device applicable both to bodybuilding and to rehabilitation.
  • Another result that the invention aims to obtain is a device for controlling and regulating such an apparatus which can ensure return to the initial position or allow such return without effort.
  • the subject of the invention is a device of the aforementioned type opposing the resistance to the flow of a hydraulic fluid to the muscular force developed by a user on an operating member associated with a piston of a jack so to order the displacement in a cylinder of a jack which it splits into two separate chambers, of volumes variables, at least one of which houses this hydraulic fluid, is connected to a hydraulic fluid reservoir open to the atmosphere by a return line to the reservoir placed under the control of a regulating means, the device further comprising at less a means for controlling the forced circulation of this fluid from the reservoir to the jack to supply the latter under a certain pressure without going through the regulating means.
  • This device is characterized in that the network comprises in parallel with the pressure regulation means at least one flow limiting device and in series with the pressure regulation means and this flow regulation body at least one selection means sending through one or the other of these elements of the fluid from the corresponding chamber.
  • the piston 4 is conventionally connected to an operating member 9.
  • a jack 3 with a rotary piston 4 has been shown, but this has no limiting value for the invention and is given only by way of preferred example, the preference being linked to the equality of the active surfaces of this piston.
  • the operating member 9 shown is a lever whose connection with the rotation shaft 10 of the piston 4 is not shown.
  • the fluid circulating in the network 2 is preferably a hydraulic fluid.
  • the network 2 comprises two main branches 11, 12 plunging independently into a reservoir 16. Each branch originates in the exhaust orifice 13 or 14 of one of the opposite chambers 7 , 8.
  • At least one regulating means 15 is provided which controls the return to reservoir 16 of the fluid coming from the corresponding chamber of the jack and this, preferably, adjustable.
  • the reservoir 16 of hydraulic fluid is open to the atmosphere.
  • the device 1 instead of comprising only at least one means 15 for regulating the circulation of the fluid issuing from a chamber of the jack, the device 1 also comprises at least one means 17 for controlling the forced circulation of this fluid from the reservoir up to this chamber to supply the latter under a certain pressure without going through said regulation means.
  • the circulation control means 17 comprises on the one hand, a pump 18 for pressurized circulation of the fluid withdrawn from the reservoir 16 and, on the other hand, arranged on the discharge pipe 19 of this pump, a connection to a element 20 limiting the pressure of the fluid, an element 21 limiting the flow of the fluid and finally an element 22 non-return, for its part, oriented to prevent any return to the reservoir without passing through the means 15 of regulation.
  • the members 20, 21 are adjustable.
  • one of the branches 11, 12 of the network 2 is connected to one of the chambers 7, 8 of the jack 3 by a simple pipe 23 connected to the reservoir 16 which allows this same compartment to call the fluid present in the reservoir 16 by simple vacuum.
  • the network 2 does not transmit the pressure prevailing in one of the chambers 7,8 to the other chamber as it would in the case of a closed circuit.
  • each means 15 for regulating the circulation of the fluid comprises at least one member 24 limiting the pressure of the fluid, in particular to a predetermined value P.
  • the corresponding branch comprises a first conduit 25 for connection to said regulating means and then another conduit 26 for connection to the reservoir 16.
  • the pressurized fluid from the pump 18 is returned to the chamber 7 or 8 by a circuit placed outside the influence of the regulating means 15.
  • the forced circulation control means 17 draws the fluid from the reservoir through a pipe 49 and by the discharge pipe 19 returns it to the chamber 7 at the level of the pipe 25 connecting the chamber to the regulating means 15.
  • the fluid which is in the chamber 7 has its pressure which rises until it reaches a value determined by the adjustment of the regulating means 15 to oppose the user a given force.
  • the regulating means 15 releases the fluid, which via the line 25 escapes from the chamber 7 then passes through the regulating means 15 and the line 26 to finally flow into the reservoir 16.
  • the user may wish the lever to be returned to the initial position. For this, he can release the lever so that the pressure in the network drops and that the non-return element 22 equipping the source 17 is released.
  • the value of the pressure delivered by the pump 18 under the control of the limiting element 20 is chosen to be just sufficient to return the lever 9 to the initial position.
  • the limiting element 21 determines a flow rate of fluid delivered by the pump 18 which is just sufficient to recall the operating member 9 to the initial position without brutality for the user.
  • the regulating means 15 and / or the pump 18 comprises means allowing the fluid to rise freely towards the jack so that the user can himself recall the lever 9 in the initial position.
  • This will, for example, be a bypass controlled by a non-return valve (symbolized in phantom in Figure 1).
  • the device comprises a double-acting cylinder, each of the two chambers of which is connected to the reservoir by a branch of the network.
  • these are each controlled by independent regulation means 15a , 15b.
  • Each chamber 7, 8 is then also placed under the influence of a regulating means 15a, 15b.
  • the two circuits 25-28 each connecting one of the chambers 7, 8 to its regulating means 15a, 15b is associated with a circuit 27, 37 passing through at least one selection member 30, 31 for the direction of flow.
  • these circuits 27, 37 pass through a distribution member 32 which allows, on the one hand, the distribution of the fluid pressurized by the pump 18, selectively at the one or the other of the circuits 27, 37 connected to one or the other of the chambers 7, 8 of the jack 3 and, on the other hand, to call in at least one of these chambers 7, 8 of the fluid withdrawn from reservoir 16 by simple depression.
  • the distribution member 32 is a drawer distributor of the type with three positions and four orifices 33 to 36.
  • the four orifices are divided into two groups of two adjacent orifices 33, 34 and 35, 36.
  • Two orifices 33, 34 of a group are respectively connected to the reservoir 16 and to the pump 18, while the two orifices 35, 36 of the other group are respectively connected to each chamber 7, 8 by a pipe 27, 37.
  • One of the positions of the drawer and, preferably, the central position allows, by its internal circuit, to put simultaneously in communication the two orifices 35, 36 associated with the chambers 7, 8 with that 33 associated with the reservoir 16.
  • one of the chambers 7, 8, pressurized by the actuation of the lever 9 drives the fluid through one of the regulating means 15a, 15b while the other chamber set in vacuum draws fluid from reservoir 16.
  • the operating member 9 can be actuated in one direction to oppose the user a determined resistance, and after the latter has released the lever 9, it will be returned to the initial position by the pressurized fluid directly from pump 18.
  • the network 2 further comprises, in parallel with the pressure regulation means 24a, 24b, at least one flow restrictor member 38a, 38b and in series with the means regulating pressure 24a, 24b and this flow regulating member 38a, 38b at least one means 39a, 39b for selecting the shipment through one or the other of these elements 24a, 38a and 24b , 38b of the fluid from the corresponding chamber 7 or 8.
  • This is for example a drawer distributor of a remote-controlled type and with two positions and three orifices.
  • the distribution member 32 selects that of the chambers which is connected to the pump using at least two detection means 41, 42 which respectively produce at least one control signal 43, 44 towards the control means 45, 46 of the distributor 32, when they detect the arrival of the operating member 9 in one of the predetermined extreme positions 47, 48 defined by said detection means 41, 42 ..
  • the amplitude of the reciprocating movement is a function of the positions of the detection means 41, 42.
  • the speed of movement of the operating member 9 can also be adjusted by acting on the element 21 for controlling the flow rate of the pump 18.
  • the device allows the force imparted to the user by the operating member 9 to be adjusted exactly by adjusting the pressure imposed in the return by the regulating means 24a, 24b.
  • the detection of the operating member 9 in a determined position should not systematically induce the previously stated mode of operation.
  • the actuator should only be printed with an action that is just sufficient for this return.
  • the device 1 is equipped with an attenuating means 50 which, under the action of the control means 17 of the circulation of the fluid, makes it possible to return the operating member 9 towards one of these extreme positions 47, 48 with a force just sufficient for this recall.
  • the attenuating means 50 comprises, disposed on a load shedding line 51a, 51b connected, on the one hand, to the tank 16 and, on the other hand, at any point 52 of the discharge pipe 19 of the means 17 for circulating the fluid, a limiting element 53 placed under the control of an isolation member 54 which is controlled by any known means during the recall of the operating member to allow the action of the limiting element 53.
  • the limiting element 53 is a limiter of the flow rate of the fluid to a value substantially close to the maximum flow rate of the circulation means 17 of said fluid, so as not to bring the cylinder as the 1st overflow and this at a very low pressure taking into account the main flow to the tank.
  • the limiting element 53 is a pressure limiter to a value, for example, of ten bars, just greater than the pressure necessary to balance the resistance normally opposed to the return of the operating member and whatever 'in any case, significantly lower than that, for example of a hundred bars, at which the main limiter 20 acts.
  • the isolation member 54 is controlled by a timed relay (not shown) which, for its part, receives, for example, information at the time of the order in reversing the position of the distributor 32.
  • the device of the invention can also be equipped with at least one means 55 for measuring the pressure which, before any action on the operating member, directly displays the value of the force to be imparted to the operating member 9 depending on the setting of the main limiter 20.
