- This exoskeleton 1 has two legs 2 and 3 and a frame 4.
- the frame is intended to be fixed on the back of a user by means of connecting means 47 of the harness type and to support a load 48.
- Each leg of the exoskeleton also includes a connecting member with the user's foot which will be described in more detail in the following description.
- the two legs 2 and 3 are of the telescopic type, that is to say that they comprise at least two segments that nest and slide into each other.
- the legs 2 and 3 comprise three segments 20, 21, 22 and 30, 31, 32 which fit together and slide into each other.
- Each leg 2, 3 is connected at one end to the frame 4, by means of a first hinge. This end of the leg corresponds to the free end of the upper segment 20, 30 of the leg 2, 3.
- each leg 2, 3 is connected to a connecting member 6, 5 by a second hinge 60, 50 which will be described in more detail with reference to Figures 6A-6B and 7A-7C.
- This end of the leg corresponds to the free end of the lower segment 22, 32 of the leg 2, 3.
- Figure 1 shows that these second joints 60, 50 are located behind the feet of the user, when it has coated the exoskeleton.
- the two legs 2 and 3 are located at the rear of the body of the user, no connection between the legs 2 and 3 and the legs of the user being necessary.
- This exoskeleton is not of the anthropomorphic type and the weight of the load fixed on the frame is directly transferred to the ground, without passing through the body of the user.
- FIG. 2 in which the load 48 placed on the frame 4 is schematically represented by dashed outlines.
- Figure 2 confirms that the exoskeleton according to the invention has no element on the sides of the user. It can not interfere with the movement of the user's arms.
- the legs of the exoskeleton remain at the back of the user's body regardless of the cycle of use (walking, running, squatting, knees to the ground %), and this at all times.
- the positioning of the legs at the back of his body allows the user to position himself naturally forward, as when he does not wear the exoskeleton.
- the exoskeleton comprises means for actuating the legs which are preferably located in the lower part of the frame 4.
- actuation means are controlled, also in a conventional manner, by means of movement detection means of the user and means for measuring the positions of the exoskeleton, as well as means for detecting the contact on the ground to ensure the phase transition between the two legs.
- these different means are connected, via a WiFi connection and / or wired through the legs, to a control device connected to the means actuating the legs and comprising, in known manner, a microprocessor, storage means and calculation means arranged to react with the indications obtained by the detection means.
- This control device thus makes it possible to control means for actuating the telescopic legs. This allows the user to walk with the exoskeleton even on uneven ground, as illustrated in FIGS. 3A and 3B.
- Figure 4A illustrates the exoskeleton 1 in a folded position. In this position, the different segments constituting each leg are nested within each other.
- the frame 4 is, in the example shown, the rack type carrier. It essentially comprises two elements 40 and 41 which are substantially perpendicular to each other.
- the first element 40 is intended to come into contact with the back of the user when the latter carries the exoskeleton and the second element 41 is intended to receive the load.
- These two elements 40 and 41 each define a plane, the plane of the first element 40 being substantially vertical when the exoskeleton is in use and the plane defined by the second element 41 being substantially horizontal in this situation.
- the second element 41 is designed to receive the means 45 for actuating the legs.
- the connecting element 6 and the second element 41 of the frame 4 are placed on the ground and the first hinge 42 is located substantially in the middle portion of the first element 40 of the frame.
- the harness 47 of the frame 4 is then substantially opposite the first element 40 of the frame.
- the exoskeleton In this folded position, the exoskeleton has a minimal footprint which is also used for its storage.
- the load is positioned on the frame 4 and then secured to the latter.
- the user can then position himself at the front of the exoskeleton and equip himself with the connecting elements 6, 5 of each of the legs 2, 3 as well as the harness 47 in an indifferent order, the frame 4 still remaining on the ground .
- the user controls the actuating means 45 of the legs, for example by means of a button 460 located at the end of the strap 46 whose length is adjustable (for example an electric cable of the spiral cable type).
- the exoskeleton 1 is positioned on the user as shown in FIG.
- first joint of each leg is able to move along an L-shaped rail 44.
- the movement of the joint along the rail can be synchronized with the movement of the legs to a position locking. It can also be passive.
- a telescope may be provided between the harness and the first frame member to allow height adjustment between them. The telescope is locked when the exoskeleton is in the position illustrated in FIG.
- FIGS. 5A and 5B illustrate the articulation between the legs and the frame.
- FIG. 5A is a schematic side view of the frame 4, with the first and second elements 40 and 41 of the frame 4.
- the second element 41 supports a rod 410 of X axis.
- This axis X is substantially perpendicular to the first element 40 of the frame and is intended to be substantially parallel to the anteroposterior axis of the user.
- each leg 2, 3 ends with a bent element 200, 300.
- the first articulation 42, 43 of each leg comprises a bent element 420, 430. At one end, this bent element 420, 430 is articulated around the axis X, this axis being therefore common to the two legs 2 and 3.
- this rotational assembly is obtained thanks to a sleeve 421, 431, through which rod 410 of the frame passes, and located at one end of the bent element 420, 430.
- this articulation is obtained by inserting the other end of the elbow element 420, 430 in a sleeve 201, 301 located at the end of the elbow element 200, 300 of each leg 2, 3.
- FIG. 5A illustrates the two legs 2 and 3 in the rest position, that is to say when the user stands straight and is static. The user is therefore in the position illustrated in FIG. 5A
- each of the axes Y2 and Y3 is situated substantially on the perpendicular common to the corresponding telescopic leg and the X axis.
- the Y2 and Y3 axes are always perpendicular to the X axis but they are inclined relative to the plane defined by the second element 41 of the frame.
- each leg may move away from a positive angle when the leg is forward and a negative angle when the leg is backward.
- the deflections around the axes Y2 and Y3 are between about 65 ° and -10 °.
- the articulation about the X axis allows the abduction and adduction of the elbows 420 and 430 (and thus the legs 2 and 3) relative to the frame 4 of the exoskeleton.
- the deflections of this articulation about the X axis are for example between 0 °, corresponding to a leg in the upright position, and 20 °, when the leg is outside the median plane of the body.
- the X axis is common to both legs and is positioned substantially in the sagittal plane.
- the two legs form an angle between them (for example by 10 °), so that they are further apart at the level of the feet of the user than at the level of the first articulations.
- each leg could be articulated at the sleeves 421 and 431 around two parallel axes and spaced from each other by a distance of about 100 mm.
- these two axes will be substantially symmetrical with respect to the sagittal plane.
- the two legs can extend substantially vertically as shown in Figure 2.
- the two axes Y2 and Y3 are then substantially in the plane of the second element 41 of the frame.
- passive elements are provided such as springs which are fixed at one end to the frame 4 and at the other end to the upper segment. 20, 30 of the leg 2, 3. These passive elements allow to generate an elastic return around a given position, for example the upright position and feet of the user.
- the articulation about the axes Y2 and Y3 can be left free when the joints 42, 43 are positioned substantially in line with the center of gravity of the load.
- Y3 could also be equipped with elements passive, like springs, or a motorization.
- the exoskeleton according to the invention makes it possible to dispense with motorisation at the level of the hip, such as is provided in particular in the exoskeleton described in document US 2012/0156661.
- This engine is designed to compensate for the torque created by the lever arm between the user's hips and the center of gravity of the load. By positioning the articulation substantially in line with the center of gravity of the load, this residual torque is eliminated.
- the connecting element comprises a sole.
- the foot of the user is not in direct contact with the ground.
- the connecting element 6 comprises a fixed part 61 and a movable part 62.
- the fixed portion 61 has an inverted L shape extending in a plane parallel to the sagittal plane.
- the small branch 610 of the L extends substantially vertically when the exoskeleton is placed on the ground, the large branch of the L 611 being in contact with the ground and forming a sole.
- the small branch 610 carries the hinge 60 with the leg 2 of the exoskeleton. It can be a ball joint type.
- the large branch 611 carries another fixed element 612 which supports a hinge 613 with the movable part 62 of the connecting element.
- the hinge 613 is located substantially at the level of the metatarsophalangeal joint of the foot of a user.
- fastening means 620 are secured to the movable part 62. These means 620 make it possible to maintain the foot of the fixed user relative to the movable part 62.
- FIG. 6A shows that, when the user's foot is on the ground, the mobile part 62 rests on the large branch 611 of the fixed part 61.
- FIG. 6B shows that, when the user lifts his foot, the mobile part 62 rotates around the hinge 613. The movable part 62 then departs from the large branch 611 of the fixed part 61 of the connecting element 6.
- the measuring means making it possible to detect the movements of the user comprise, for example, two force sensors placed in the sole plate 611 of the fixed part 61, to measure the load transfer of the user on the foot.
- These measuring means also include a potentiometer for detecting the angle of heel detachment of the user.
- This information is processed conventionally to control the means for actuating the legs, so as to follow the movements of the user.
- the invention also provides another embodiment of the connecting element, wherein it has no sole, the foot of the user coming directly into contact with the ground.
- the connecting element 7 comprises a rigid element 71 of U-shaped caliper type with two side walls 710 and 711 intended to come on either side of the user's foot and a bottom 712 connecting the two side portions 710 and 711 and intended to come in front of the heel of the user.
