    [0001] FIELD OF THE DISCLOSURE The present invention relates to the field of assistance with displacements. More particularly, the invention relates to a device for assisting the movements of which the progression is done by markets, steps or steps not slipped.
    [0002] BACKGROUND OF THE INVENTION In the field of travel assistance, numerous devices have been developed, with the aim of helping persons with reduced mobility or of relieving persons temporarily disabled and in the rehabilitation phase, or to assist hikers on difficult terrain.
    [0003] The devices, the simplest and best known, are walking devices such as cane, cane, cane with support for the elbow, mountain cane and walker with wheels. These devices comprise a manual gripping member and an elongate portion whose end is intended to bear against the ground; they can be used singly or in pairs for some. The document FR2845894 for example describes a device characterized in that it comprises a resilient energy recovery means for projecting the elongated part (of a cane for example) forward during the detachment of the lower end of the by restoring the elastic energy stored during the support of the hand on the manual gripping member. These devices are simple and accessible, but do not provide assistance with the movement of the lower limbs. The movement aid of the lower limbs is particularly developed in devices of the type 3034986 2 "exoskeletons". Thus, EP1637113 discloses a walking aid device having a hip joint power generating system for providing an auxiliary force to the movement of a lower limb. and on the other hand, a knee joint rotation power generation system. The two systems are interconnected. The device comprising these systems as well as fixing means on the human body, are worn by the user, at the waist and laterally at the lower limbs. Document EP2554150 mentions another type of device integral with the user's lower limb, comprising thigh, leg and foot units as well as joint units, connected to one another and located on the front and the side. external of the lower limb. Document US20090014042 describes another type of device, aimed at reducing the load on the user's legs. This device is maintained at the level of the crotch and at the feet of the user, the mechanical and connecting systems being located between the 2 lower limbs.
    [0004] These devices have the disadvantage of being difficult and restrictive to use because their introduction, porting and removal are not easy. Other, simpler devices are provided at the level of the user's shoe. The document FR2972906 discloses a shoe comprising a footwear and a sole, this sole comprising two main parts hinged together. These two parts are articulated along a first horizontal transverse axis located substantially under the natural articulation between the forefoot and the rear part of the foot. A system consisting of spring lever arms, hinge pins and elastic modulus (forming a damper) gives the 3034986 3 shoe the characteristic of: (1) transform, during the impact of the shoe on the ground , the kinetic energy in potential energy, by putting the elastic modulus under pressure (2) to maintain the module under pressure in phase 5 of support of the foot on the ground, (3) to release the elastic modulus in phase of propulsion (when the foot stands up to take another step). US6684531 and US5282325 describe 10 different types of spring shoes. The soles are equipped with spring systems, assisting in particular the lifting of the heel of the user during a walking action, and thus reducing the muscle energy to be produced by the calf.
    [0005] These shoes provide assistance to the lower limbs during a walking or running action. The main disadvantage is that the energy restored remains low, because it is more or less proportional to the energy resulting from the impact of the shoe on the ground.
    [0006] EP2699323 relates to a system for assisting the movements of a user's foot, adapted to a support, gliding board or snowshoe. It comprises a footwear portion whose front end is pivotally mounted relative to the support and a spring securable to the support so as to be applied to a bearing zone of the footwear part by exerting pressure on said bearing zone. when it is close to the support. In this case also, the energy restored is a function of the energy resulting from the movement of the user as well as the stiffness of the spring. For the comfort of the user, a lower spring stiffness seems preferable, but will bring less assistance to the effort.
    [0007] It is an object of the present invention to provide a motion assistance device which obviates the disadvantages of state of the art devices. An object of the present invention is in particular to provide a simple device for use and installation, allowing the user to adapt the desired level of assistance to the lower limbs, by an external supply of energy , of adjustable intensity.

    [0010] BRIEF DESCRIPTION OF THE DRAWINGS The invention will be better understood in the light of the following description of the particular and nonlimiting embodiments of the invention with reference to the attached figures among which: FIG. embodiment of the invention, intended to assist a movement in steps or markets, comprising a handle operable by the upper limbs of a user; FIG. 2 shows a view from above of the displacement assistance device according to the first embodiment, having a variant of shape of the first and second planar bodies; - Figure 3 shows a top view, according to the sectional plane A shown in Figure 1, the displacement assistance device according to the first embodiment; FIG. 4 shows a sectional view of a variant of the displacement assistance device according to the first embodiment; FIG. 5 shows a second embodiment of the invention intended to assist a displacement in slipped steps, comprising a handle actuable by the upper limbs of a user; - Figure 6 shows a third embodiment of the invention for assisting a displacement in steps 3034986 8, comprising a cylinder actuated by a motor, which is controlled by a control circuit; FIG. 7 presents another embodiment of the invention intended to assist a displacement by market or run. DETAILED DESCRIPTION OF THE INVENTION FIG. 1 represents a first embodiment of the invention. In this figure, a displacement assistance device comprises a first element consisting of a first planar body 1, for example of rectangular parallelepipedal shape, the length of which is in the direction of travel and the width is perpendicular to the direction of travel. walking. By way of illustration, the first planar body 1 may have a length of the order of 15 to 35 cm and a width of about 5 to 15 cm. In practice, the dimensions can be adapted to the size of the feet and / or shoes of the user.
    [0011] The upper face of this first planar body 1 is intended to be in contact with a foot of a user. By contact means direct or indirect contact via a support. For example, the upper face of the first planar body 1 may be in direct contact with the foot of the user or in indirect contact with it, by means of a shoe or other support. The upper face of the first planar body 1 comprises fastening means 3 for hanging a foot or a shoe of the user. These fixing means 3 are for example hooks, present at the front portion and the rear portion of the first planar body 1 and able to hook on the shoe of the user. They may also be made of thongs, able to secure the foot or the shoe. According to an alternative embodiment, this first planar body 1 is formed directly by the sole of the shoe, and in this case it is not necessary to have additional fixing means. The displacement assistance device also comprises a second element 2 forming a second planar body 2, for example of rectangular parallelepipedal shape, opposite the first planar body 1 and articulated with respect thereto. By way of illustration, the first 1 and the second planar body 2 may be made of at least one light material from: a type of wood a rigid plastic a light alloy based on aluminum and / or titanium a composite material of carbon fiber type.
    [0012] According to an advantageous variant, the second planar body 2 is hollowed out and allows the interlocking of the first planar body 1, as illustrated in FIG. 2. This particular shape favors the lightness of the assistance device for displacements and reduces its bulk. The first planar body 1 and the second planar body 2 are connected by connecting means 4 allowing the spacing of one relative to the other, for example by pivoting and / or by translation. It may be for example a hinge fixed on the underside of the first planar body 1 and on the upper face of the second planar body 2, in their front parts in the direction of travel, as shown in FIG.
    [0013] In a variant of this embodiment, the connecting means can be mounted on movable slides 5 slidable in longitudinal translation on at least one rail 6; the rail 6 is itself fixed on the upper face of the second planar body 2, as illustrated in FIG. 3. The movable slides 5 are lockable, thus making it possible to position the connecting means (for example the axis of the hinge ) between the front and the middle portion of the second planar body 2, and then lock them when using the device. The longitudinal translation of the connecting means makes it possible to modify the position of the first planar body 1 with respect to means 7, 8, 9, 10 to apply a thrust force tending to separate the two planar bodies from one another.
    [0014] The spreading amplitude can thus be adjusted according to the needs of the user. The displacement assistance device according to the first embodiment comprises the means 7, 8, 9, 10 10 for applying a thrust force, tending to move the first and second planar bodies 2 away from each other. These means comprise a handle 7 actuated by an upper limb of the user, cooperating with a spacer placed between the first 1 and the second planar body 2. This spacer 15 constitutes a lever transmitting a thrust force, generated by the actuation of the actuable handle 7 forward in the direction of travel, and tending to move the first 1 and the second planar body 2. In the particular example shown in Figures 1 and 3, the piece 20 spacer comprises: - an axis of rotation 8, said transverse, because perpendicular to the longitudinal axis of the second planar body 2; this transverse axis of rotation 8 is fixed on the second plane body 2 and advantageously located in a front part thereof, that is to say between the front and the median of the second planar body 2; two lever arms 9 secured at one of their ends to the transverse axis 8; a spacer 10 connecting the other ends of the lever arms. Advantageously, the spacer 10, parallel to the transverse axis 8, is in contact with a rear portion of the first planar body 1. When the thrust force is transmitted from the actuable handle 7 to the spacer, the spacer 10 pushes the rear portion of the first planar body 1, which tends to move away from the second planar body 2, as shown in Figure 1. To limit the friction due to contact between the spacer 10 and the first planar body 1, the spacer 10 5 may advantageously comprise a roller bearing. Moreover, the lower face of the first planar body 1, in particular in the rear zone of contact with the spacer 10, may be provided with a material that minimizes the rolling resistance of the roller bearing, for example a steel sheet. 10 of 2mm thick. According to a variant, the connecting means and the means for applying a thrust force can be arranged so as to form a deformable parallelogram-type system, allowing the first flat body 1 to be raised relative to the second planar body 2, as illustrated. in Figure 4. This shows for example a variant with 4 lever arms, at rest (a) and lifting situation (b).
    [0015] The actuatable handle 7 is connected to one end of the transverse axis of rotation 8 and is substantially perpendicular to the lever arms 9. In a position of use, the user's shoe being hooked to the first planar body 1 according to its length, the articulation 25 between the first 1 and the second planar body 2 being located at the front and the spacer 10 at the rear, the actuatable handle 7 is located on the side corresponding to the outside of the foot of the user, allowing gripping by the associated upper limb.
    [0016] The connection between the actuable handle 7 and the transverse axis of rotation 8 may be fixed or adjustable, for example by means of a ratchet mechanism or a clutch mechanism. These mechanisms make it possible to adapt the position of the handle to the morphology of the user, for an ergonomic grip. For example, the clutch mechanism adjusts the angle between the actuable handle 7 and the lever arms 9, in steps of 0.5 ° to 5 °. The adjustment of this angle also makes it possible to adapt the thrust force transmitted to the first planar body 1 and thus to modulate the intensity of the external energy supplied.
    [0017] According to a preferred variant, the actuatable handle 7 consists of two parts, a base connected to the transverse axis of rotation 8 and a removable part. The base may for example be constituted by a tube of internal diameter of 2cm and length 20cm. The removable portion may for example consist of a dural tube, aluminum alloy and copper resistant and lightweight, outer diameter 2cm and length between 90 and 150cm. The removable portion may be inserted into the base 15 to use the movement assistance device and transmit thrust forces to the lower limbs; this removable portion may also be removed from the base on a ground that does not require external energy supply to the lower limbs.
    [0018] According to this first embodiment, the motion assistance device can be used to walk or run, in flat or steep terrain. The user positions each of his feet on a device, secures his shoes with the first planar bodies 1 through the fastening means 3, the second planar bodies 2 being in contact with the ground. The user, in the rest position, has an actuable handle 7 to his right (relative to the device secured to his right foot and hereinafter referred to as the actuable handle 30) and an actuable handle 7 to his left (relative to the device secured to with his left foot and subsequently called the 7 left sleeve), which he can seize to start his progression at no markets or at a pace.
    [0019] 35 In a walking process, there is an alternation of temporal phases describing the movement of the feet: 3034986 13 - DG phase: right foot resting on the ground in the CEO position, left foot mobile until reaching a more advanced position PGG - Phase GG: left foot resting on the ground in PGG position, 5 moving right foot until reaching a more advanced position PpG + i - Phase Dn + 1: right foot resting on the ground in position Ppn + i, movable left foot up 'to reach a more advanced position PGG + 1 10 - Phase Gn + 1: left foot resting on the ground in position PGG + 1, right foot moving until reaching a more advanced position Ppn + 2 - Etc ...
    [0020] 15 Correlatively, the movement of the arms usually consists of an alternation of swaying forward and backward, in opposition to the movement of the feet: 20 - Phase DG: right foot in ground support in the position CEO, left foot mobile up to to reach a more advanced position PGG, right arm in forward swinging, - Gn phase: left foot resting on the ground in PGG position, moving right foot until reaching a more advanced position PDn + i, left arm in front swinging - Phase Dn + 1: right foot resting on the ground in position Ppn + i movable left foot until reaching a more advanced position PGG + 1, right arm swinging forward, - Phase Gn + 1: left foot resting on the ground position PGn + i 30 movable right foot to reach a more advanced position PDn + 2, left arm in forward swing, - Etc ... During DG phase, the user has his right foot in ground support, the left foot is mobile to reach a more advanced position and correlates the right arm moves forward; it thus pushes the actuable handle 7 straight forward, which generates a thrust force transmitted by the spacer to the first planar body 1 of the device secured with his right foot. The first planar body 1 deviates from its rest position opposite the second planar body 2, and lifts the user's right foot. This uprising initiates the movement of the right foot, foot support during phase Dn. The left foot reaches its more advanced position PGn: we then go to the Gnr phase during which the left foot is resting on the ground. The right foot is movable to reach a more advanced position 10 Ppn-ri, correlatively the user operates a movement of the left arm forward, it thus pushes the handle 7 left to the front, which generates an effort of thrust transmitted by the spacer to the first planar body 1 of the device secured with his left foot. The first planar body 1 deviates from its rest position vis-a-vis the second planar body 2, and raises the user's left foot. This uprising initiates the movement of the left foot, support foot during the Gn phase. The right foot reaches its more advanced position PDn + i: it then goes to the Dnilf phase during which 20 the right foot is in support of the ground. And so on. The displacement assistance device according to the invention thus provides during each time phase when the bulk of the weight of the body rests on a given foot, an external energy (generated by the movement of the arm, in this first embodiment). allowing to lift or help lift the foot, and facilitating the walking process. The intensity of the supplied energy, which can be associated with the spacing distance between the first and second planar bodies 2, is dependent on the range of motion of the arms and the angle between the handle. actuable 7 and the lever arms 9 of the spacer. Thus, for an identical arm movement, the displacement assistance device according to the invention makes it possible to adapt the intensity of the energy supplied by adjusting the angle between the actuatable handle 7 and the lever arms. , in particular by implementing a link comprising a clutch mechanism. For example, in the rest position, if the actuable handle 7 makes an angle of 10 ° forward relative to the vertical position, the actuation of the handle 7 by the upper limb of the user in use phase will transmit less thrust energy than when the actuable handle 7 is initially adjusted to the vertical position. If, in the rest position, the actuable handle 7 makes an angle of 10 ° to the rear relative to the vertical position, actuation of the handle by the upper limb of the user in the use phase will transmit more than thrust energy. According to a variant particularly adapted to a progression in rise with a strong inclination, the second flat body 2 may be provided with an additional heel, 15 to reduce the external energy input to lift or help lift the foot, and facilitating uphill walking. Fig. 5 shows a second embodiment of the invention. The displacement assistance device of the second embodiment also comprises a first element 1 forming a first planar body 1 and a second element 2 forming a second planar body 2, interconnected by connecting means 4 allowing the pivoting of relative to each other. The second planar body 2 comprises fastening means 30, making it possible to secure its lower face with a ski. According to an alternative embodiment, the second planar body 2 may be the ski itself. The upper face of the first planar body 1 comprises fastening means 3 for hanging a shoe, and in particular a ski boot. According to a variant, the first planar body 1 may be the sole of the ski boot itself.
    [0021] The connecting means 4 between the first 1 and the second planar body 2 as well as the means 7, 8, 9, 10 for applying the thrust force may be the same as those described in the first embodiment. According to this second embodiment, the device for assisting the movements can be used to slide, in flat or steep terrain and in particular to make trips in ski touring or cross-country skiing. The user positions each of his feet on a device, solidarises his shoes with the first planar bodies 1 through the fastening means 3, the second planar body 2 being secured to the skis. The user, in the resting position, has an actuable handle 7 on his right (relative to the device secured to his right foot and subsequently called the actuatable handle 7 right) and an actuable handle 7 to his left (relative to the device secured to with his left foot and subsequently called the actuable sleeve 7 left), which he can grasp to start his progression with slipped steps. During a progression with slipped steps, there is the alternation of the temporal phases described above. The displacement assistance device is therefore performed in the same manner as described above.
    [0022] The actuable handles 7 having a removable part are particularly suitable for this type of use: in fact, when the ground is for example downhill, the user no longer needs to bring external energy for his progression. , can remove the removable parts of the associated bases and use them as conventional sticks, helping in particular to keep the balance.
    [0023] Figure 6 shows a third embodiment of the invention.
    [0024] This embodiment differs from the previous ones in particular by the means used to apply the thrust force tending to move the first 1 and second planar body 2 of the assistance device to displacements. In this embodiment, these means comprise a jack 12 actuated by a motor 13 and controlled by a servocontrol circuit 14. The jack 12 can be in a lowered position, at rest or in a high position, able to apply the pushing force. For this high position 10 of the jack 12 transmits a thrust force to the first planar body 1, the latter comprises a stop 15 vis-à-vis the cylinder 12. The control circuit 14 can be connected to sensors 16 by For example, pressure or movement, located at the upper face of the first planar body 1. According to the information received by the sensors 16, the circuit 14 controls the motor 13 to actuate or not the actuator 12. The circuit servo 14 can also be connected to a manually operable button. During his movement, the user can thus decide when he wishes to trigger the external supply of energy, able to relieve his lower limbs and necessary for its progression. The various means for applying the thrust force tending to move the first and second planar bodies 2 of the displacement assistance device, described for the three preceding embodiments according to the invention, can also be combined, in a fourth embodiment according to the invention, not shown.
    [0025] Fig. 7 shows a fifth embodiment according to the invention. The motion assistance device has a first member 17 that can be attached to the heel or instead of the heel of the user's shoe. The fastening means 19 are for example hooks or glue.
    [0026] The connecting means between the first 17 and the second element 18 are constituted by a bellows system 20, the assembly formed by the first element, the second element and the bellows constituting a cavity 21. A pipe 22 connected to 5 this cavity 21 is connected to a pump 23, which is part of the means for applying the thrust force tending to move the first 17 and the second element 18. In the rest position, the displacement assistance device has the first 17 and second element 18 very slightly spaced, the bellows 10 being in the retracted position. In the active position, the pump 23 injects a fluid, for example air, into the pipe 22 to fill the cavity 21. Thus, the air pressure in the cavity 21 allows the first 17 and the second element to be displaced. 18. This pump 23 can be operated manually or by an electric motor. For manual actuation, it will be introduced in particular a system of the type of old pumps to sulfate, for which the actuation of a lever 24, by the arm of the user, allows the pressurization of a fluid.
    [0027] According to this fifth embodiment, the motion assistance device can be used to walk, run or slide, in flat or steep terrain.
    [0028] The user sets a first member 17 at each heel of his shoes. The pump 23 can be placed in a backpack carried by the user. In the case of manual actuation of the pump 23, two levers 24 which are grippable by the right and left hands of the user are connected to the pump 23. The right lever 24 actuates the pump 23 which sends fluid into the cavity 21 of the device integral with the right shoe; the left lever 24 actuates the pump 23 which sends fluid into the cavity 21 of the device integral with the left shoe.
    [0029] Then there is the alternation of the temporal phases during a displacement, described previously.
    [0030] During phase Dn, the user has his right foot resting on the ground, the left foot is movable to reach a more advanced position and correspondingly the right arm operates a downward movement; it thus pushes the right lever 5 downwards, which actuates the pump and generates a thrust force, related to the pressure of the fluid, transmitted to the first element 17 of the device secured with its right heel. The first member 17 moves away from its rest position opposite the second member 18, and raises the right heel of the user. This uprising initiates the movement of the right foot, foot support during phase Dn. The left foot reaches its more advanced position PGn, the left arm moves upwards. We then go to phase Gn, during which the left foot is in support of the ground. The right foot is movable to reach a more advanced position Ppn-ri, correlatively the user operates a movement of the left arm down, it pushes the lever 24 left down, which actuates the pump and generates an effort thrust, related to the pressure of the fluid, transmitted to the first element 17 of the device secured with its left heel. The first member 17 deviates from its rest position vis-à-vis the second member 18, and raises the left heel of the user. This uprising initiates the movement of the left foot, support foot during the Gn phase. The right foot reaches its more advanced position, the right arm moves upwards. We then go to the phase Dn + 1, during which the right foot is in support of the ground. And so on. The movement assistance device according to the invention thus provides during each time phase when most of the weight of the body rests on a given foot, an exogenous energy to lift or help lift the back of the foot, and facilitating the walking process. By exogenous energy source is meant any energy that is not directly derived from the kinetic or potential energy of the displacement itself. As has been explained in the description of the different embodiments of the invention, this source of exogenous energy can be derived from the upper limbs of the user or from a source of electrical energy. According to a variant, the pump 23 can be activated by an electric motor, controlled by a control circuit connected to sensors. In this case, the electric motor, the control circuit and the connection systems can be arranged in a backpack worn by the user. 10
