Definitions

  • the present invention relates to a device for assisting the movement of the feet, intended in particular to promote the circulation of blood in the lower limbs, in particular for people who have difficulty walking or who are physically unable to walk. walk.
  • Document FR.A.2 490 967 has also proposed a pedal device of simpler basic design which requires an active movement of flexion-extension of the articulation of the foot, while the movement of the knee is maintained very weak and the hip is almost completely at rest.
  • This device consists of a base inclined in a plane towards the user, on which are rotatably mounted, by their lower ends, two pedals practically parallel to each other provided, at their lower part, with elastic means which push them, so continues, to a lower position.
  • the goal that the applicant has set is to propose a simplified device which allows the user to carry out the flexion movement - extension of the articulation of the foot, without any external constraint.
  • the device for moving the feet of the invention comprises in a known manner from the aforementioned documents a chassis, suitable for being placed on a work surface, and at least one housing for the feet, which is mounted to oscillate around an axis.
  • the axis of oscillation of the housing is located in an area which corresponds substantially to the axis of articulation of the two feet of the user in position in the housing, the more the housing is secured to the chassis, according to said oscillation axis, at a height such that there is no contact with the work surface when the housing oscillates around its axis.
  • the housing is somehow suspended from the axis of oscillation like a swing.
  • the feet rest only on the housing which can oscillate freely, without constraint, around its axis. Due to the location of the axis of oscillation of the housing according to the zone of the axis of articulation of the two feet when they are placed in the housing, it is understood that the movement of the foot thanks to the device of the invention will not cause any difficulty for the user.
  • the housing being constituted by a bottom for the sole of the foot, a rear upright forming a rim for heel and two lateral uprights, each lateral upright is secured to the chassis by a rod forming an axis of oscillation.
  • the bottom is composed of several transverse, individual plates, the two ends of which are fixed to the lateral uprights and which are angularly offset and are shaped according to the general natural shape of the sole of the foot.
  • This particular arrangement allows a better fit of the device to the feet of the user and provides better comfort during its use.
  • the rear upright is advantageously inclined relative to the general direction of the bottom, by an angle of the order of 100 to 130 °. This avoids any possible crushing of the Achilles tendon when the foot is extended.
  • the chassis providing the seat of the device on the work surface is made up of a U-shaped frame, the lateral branches of which have a step in height for fixing the axis of rotation and the central branch of which is opposite the rear part of the housing, in the operating position.
  • a frame can advantageously be produced by molding a thermoplastic material.
  • the device of the invention may have only one housing for both feet; in this case the oscillation movement is identical for both feet.
  • This very simple version can be recommended for people with specific problems on a given leg, the valid leg can cause movement of the other foot.
  • It can also include two housings, one for each leg, each housing oscillating independently of the other along the same axis of oscillation.
  • the chassis which comprises a U-shaped frame, also comprises an intermediate branch, mounted inside the U, equidistant from the two lateral branches plus the axis of oscillation of a housing. given is fixed to the step in height on the one hand of the middle branch and on the other hand of a lateral branch.
  • the device for assisting the movement of the feet of the invention may also include at least one protective coating for the feet, for example in a textile material, capable of coming to fit on or around the housing.
  • the protective covering which fits over the housing, acts as a sort of slipper, integrated into the device.
  • it may include means for driving the axis or axes of oscillation in oscillation.
  • the device 1 for assisting the movement of the feet which is shown in FIG. 1 is a simplified version in which the two feet will be animated together with the same movement.
  • This device 1 comprises a frame 2 which must ensure the stability of the device when it rests on the work surface 3.
  • This frame 2 must also serve as a support for the housing 4 for the feet of the user. More precisely, this housing 4 is mounted oscillating with respect to the frame 2, along a common axis of oscillation D.
  • the frame 2 has a general U-shape, with two lateral branches 2 a and 2 b and a central branch 2 c .
  • Each of the two lateral branches 2 a , 2 b has a step in height 2 d , which, in the example illustrated, has the shape of an isosceles triangle with the vertex which is opposite the work plane 3 .
  • the housing 4 has a bottom 5, two lateral edges 6, 7 and a rear edge 8.
  • the rear edge 8 keeps the user's foot at the heels in the housing 4.
  • the two lateral flanges 6, 7 of the housing 4 are secured to the two lateral uprights 2 a , 2 b of the frame 2 by systems of rods and rivets not shown, which are mounted towards the upper end of the elevations 2 d of the uprights lateral 2 a , 2 b , aligned with each other, along the axis of oscillation D.
  • the bottom 5 of the housing 4 is preferably made up of transverse plates, 5 a , 5 b , 5 c , from the front to the rear of the housing, in consideration of the position of the user. Said transverse plates are separated from each other. They are fixed at their two ends to the side edges 6, 7.
  • Each transverse plate 5 a , 5 b , 5 c is moreover angularly offset with respect to the general direction of the bottom 5, so as to conform as perfectly as possible to the natural shape of the soles of the user's feet, when those these are in position in the housing 4.
  • the frame 2 and the housing 4 are advantageously made by molding in a thermoplastic material.
  • the operation of the foot movement aid device is as follows.
  • the user is preferably seated, barefoot, or feet in socks. It has its two feet next to each other in the housing 4 so that its heels are applied to the rear edge 8.
  • the implementation of the device is done at the discretion of the user, by simple tilting of the housing 4 relative to the axis of oscillation D. This tilting of the housing 4 and therefore of the feet of the user causes a movement of extension and retraction of the leg muscles which activates blood circulation.
  • FIG. 3 shows the position taken by the foot 9 during tilting of the housing 4 towards the front, that is to say during the movement of the foot corresponding to an extension.
  • FIG. 4 shows the position taken by the foot 9 during the tilting of the housing 4 towards the rear, which corresponds to the retraction movement of the foot 9.
  • the leg itself 10 retains the same position in the two movements of extension and retraction of the foot: only the foot 9 moves.
  • the position of the axis of oscillation D has been determined relative to the housing 4 so that this axis of oscillation D is in the zone which corresponds substantially, for the two feet 9, to the axes of articulation of the foot c that is to say substantially at the level of the malleoli of the tibia and the fibula.
  • This is a necessary condition so that the movement of the feet, which is achieved by means of the device 1 by the swinging around the axis of oscillation D, is as natural as possible, reproducing the movement of the ankles, without displacement of the legs. back and forth.
  • the housing 4 must be at a sufficient height relative to the axis of oscillation D so that there is no contact between said housing 4 and the worktop 3 at any time.
  • a device 1 has been produced which is suitable for a large majority of users, with the following configuration.
  • the height H of the axis of oscillation D relative to the work plane is of the order of 110 mm.
  • the distance L from the axis of oscillation D to the rear edge 8 is of the order of 85 mm.
  • the distance l from the axis of oscillation D to the general direction of the bottom 5 is of the order of 60 mm.
  • FIG. 2 shows a perspective view of an alternative embodiment of a device 11 for assisting the movement of the feet on which the movement of each foot is independent.
  • This device 11 is particular compared to that which has just been described by the fact that it has two housings 12, 13, one for each leg, said housings being mounted oscillating with respect to the same axis of oscillation D.
  • the frame 14, which has the same U-shaped configuration as the previous frame 2 has a middle branch 15, with a step in height, of triangular shape.
  • the housings 12, 13 are secured to the frame 14 by rod / rivet systems, not shown, which are mounted at the upper ends of the notches in height of the lateral uprights 14 a , 14 b and of the median upright 15, as is clearly seen on the figure 2.
  • the housings 12, 13 are adapted to the natural configuration of the base. Their bottom is also composed of three transverse plates which can have a slightly curved shape.
  • the rear part of the housing includes not only the rear flange 16 on which the heel rests, but also a transverse plate, arranged more in height, forming a rear extension 17.
  • the rim 16 is inclined relative to the general direction F of the bottom by an angle a which is of the order of 110 to 130 °.
  • the rear extension 17 is also inclined in the same direction, with respect to the rear edge 16. This arrangement is understandable on examination of FIG. 3.
  • the rear extension 17 makes it possible to support the foot during the extension movement.
  • the position of the rear extension 17 is such that it does not cause contact with the work surface 3 during the retraction movement of the foot, as illustrated in FIG. 4.
  • the user can carry out any movement of the feet simultaneously and with the same rocking as was the case of the device 1 with a single housing or alternatively simultaneous movements of the two feet or to movements involving only one foot at a time, the other being at rest.
  • the invention is not limited to the embodiment which has just been described by way of example. It is also understood that the operation which has just been described while the user was in a seated position, can also extend to persons having a lying position. It suffices for this to secure the device so as to avoid any sliding, during use, on the work surface.
  • the device can also be equipped with a protective coating, in particular in a textile material, making it possible to protect the feet of the user during use.
  • a protective coating in particular in a textile material, making it possible to protect the feet of the user during use.
  • this coating of use just fits on or around the housing so as to integrate with it. It surrounds the user's foot to form an envelope, protecting the foot in particular from the cold, like a slipper or a heater.
  • the primary goal sought by the applicant is to propose a simplified device, allowing the user to spontaneously perform simple movements of the ankles, it is nevertheless possible to match the device of the invention with complementary means making it possible to assist the user in the practice of these movements.
  • complementary means may for example consist of means for oscillating the rods mounted on the axis of oscillation of the device, so that the housing or the housings are driven in a rocking movement at a predetermined angle of oscillation. and according to a frequency also predetermined. Under these conditions, the device of the invention becomes a medical exerciser.
  • Said additional means can, in another example, consist of means for braking the housings during their rocking, forcing the user to exert a certain pressure to carry out said movements.
