Description

2702508 -

  The present invention relates to a device for training and / or rehabilitating a person in an aquatic environment as well as the associated reeducation method. Rehabilitation pools are well known in the medical community and more particularly for

rehabilitation exercises.

  Indeed, people working in water are relieved by Archimedes' push which reduces 1 o their own weight and provides them with homogeneous support

on all parts of the body.

  This has a beneficial effect on both the joints

than on the muscles.

  However, these pools pose several problems.

  These pools have a given depth, which corresponds to

  generally lays in immersion up to the shoulders

of a person of average height.

  Also, people of lower height are embarrassed.

  born by depth and tall people

  size are not sufficiently submerged.

  In large pools, the solution

  consists of providing a sloping pool bottom.

  In smaller pools, the solution

  tion consists of providing an attached, movable floor

  in height, which forms a walking corridor.

  Such corridors are suspended from an external arm secured to a screw-nut assembly resting on the

  peripheral edge of the pool, just like the

  positive for launching in a basket.

  The person goes back and forth on this cou-

  to sleep in order to exercise.

  We understand that only certain parts of the body

  are requested which limits the effects of re-

  education and variety of exercises.

  The rehabilitation and / or training pools for sportsmen are of increasing size

  on the one hand restricted to limit investments

  operating costs and on the other hand to allow the number to be multiplied in order to vary the applications including within a

same establishment.

  This is how swimming pools are more and more often provided with a counter-current installation.

  despite the small size of the catchment area,

  high performance sports and variants

rehabilitation exercises.

  The power of the current is adjustable and even pro-

  grammable with time-power cycles.

  The water flows generated forming the currents have been improved and some swimming pools are equipped with a

  paddle wheel arranged at one end of the lower

  sin which pushes back a lami- flow at the other end

  through a suitable opening and after-

  wise under the pool bottom, more particularly in a double bottom provided for this purpose or by lateral channels formed laterally in the pool itself. Such pools are sold in particular

  under the trademark "Swimex Pool".

  In order to improve rehabilitative exercises

  tion, the present invention provides an improvement

  counter-current type swimming pools by

  combining with a movable floor, adjustable in height

tor.

  Indeed, people can remain static while working certain parts of the

  body only by exerting a resistant effort.

  In addition the person can expose his body in all orientations, face, side, profile and more thanks to the combined effect of the height adjustment,

  the targeted areas are perfectly targeted.

  This device nevertheless retains the advantages of the movable floor in the sense that it allows a passage from the apparent weight to the actual weight.

  In the case of the present invention, the effect

  so much is even more interesting since it allows to vary an additional parameter which is the

force generated by the current.

  The device according to the invention also makes it possible to conserve the advantages relating to the gradual launching or reduction of depth for the

  short people, especially children.

  The device according to the invention furthermore comprises very specific means of displacement in height of the floor which limit the overall height, which are simple to produce, which

  offer all the guarantees of security and which

  put the clutter in the pool.

  To this end, the device according to the invention, intended for sports training and / or the rehabilitation of people in an aquatic environment, is characterized in that it comprises a basin provided with means for circulating water in order to create a current in a given direction and a movable floor provided with means of displacement in height compared to the bottom

  of this basin so as to adjust the immersion height

person.

  According to another characteristic of the invention, the current is oriented along the longitudinal axis of the basin. Preferably, the current is a

  surface laminar current over a given height. According to one embodiment, the floor covers the entire bottom of the basin.

  According to one embodiment of the invention, the means of displacement in height comprise four bent arms, articulated relative to the edge of the

  swimming pool at one of their ends and fitted with

  support elements provided to cooperate with the underside of the floor at the other end, as well as

  lifting means arranged between the edge of the

cine and each of the arms.

  According to another characteristic, the floor comprises

  takes retractable guardrails defining

walking paths.

  The floor includes a moving mat driven in

  displacement in the same direction as the current.

  The rehabilitation process according to the invention which puts

  using the device of this same invention

  is to submerge the person, to adjust the cost

  rant with a power adapted to the capacities of resistance of this person, and progressively,

  during the same session or successive sessions

  ves, to raise the floor so as to transfer the resistance forces to the current in force of

  recovery of the person's own weight.

  The method also provides for orienting the person relative to the direction of the current according to the therapies

and affected areas.

  You can also place the person on the floor in a high position and then immerse him gradually

by lowering this floor.

  The invention is described below according to a mode of

  particular realization with regard to the an-

  attached to which: FIG. 1 represents a perspective view of the basin according to the invention equipped with a current generator,

  Figure 4 shows schematically the ram-

  retractable bards provided on the movable floor, FIG. 5 represents a movable floor with movable conveyor, and FIGS. 6 A and 6 B represent two of the phases

of the method according to the invention.

  In Figure 1 there is shown, the basin 10 of the device which is equipped with a movable floor 12 comprising means 14 for displacement in height

  of this floor and means 16 for circulating

  tion of water so as to create a stream of water.

  The pelvis is substantially rectangular in shape

  to allow good water circulation

  song that the direction of the current generated by the means for circulating the water is oriented

  along the longitudinal axis of this basin.

  As shown schematically on

  Figures 2 and 3, the circulating means

  tion of the water comprises a pump 18, means for pumping the water into the basin at one of the ends and means 22 for sucking the water from

the opposite end.

  Between the two there are water supply pipes

  tion. Preferably, a double bottom is provided under the bottom of the basin, which allows circulation of the

  return flow without disturbing the outward flow.

  In known manner, there are basins equipped in this way which also include a pump of the impeller type with a water outlet mouth in the basin which is rectangular in shape, which makes it possible to generate a flow of water. laminar on

  a given and limited height, of the order of 40 cen-

timers to fix ideas.

  These circulation means are adjustable and

  some are equipped with a timer for recording

  record specific sequences with a chain

pre-established.

  The floor 12 comprises a plate 24 of dimensions substantially equal to the interior dimensions of the basin. The height displacement means 14 comprise

  four arms 26 bent Each of these arms is articulated

  butted around an axis 28 integral with the edge of the pelvis

  by one of its ends while the other ex-

  end supports the end of a transverse shaft 30

sal mounted free to rotate.

  The arms are arranged laterally and are housed between the edge of the basin and the edge of the floor because the two shafts, each located between the two arms of the same end of the basin, are arranged under

the movable floor plate.

  Cylinders 32 are arranged between each of the arms and the edge of the basin. These cylinders are connected so

  known to a pressure center, not shown.

  In Figure 4 there is shown the floor 12 and more simply the plate 24 on which there is provided a pair of guardrails 34 retractable between two positions one vertical in which

  said guardrails are protruding and the other horizon-

  in which the guardrails are in boxes

  ments 36 arranged in the thickness of the plate.

  The movements of these guardrails may be advanced

  taggedly motorized but they can be put

  in place manually without significant effort.

  In FIG. 5, a variant of the floor is shown in which the plate 24 is equipped with a

2702508-

  moving belt 38, which is driven by mo-

  tor 40, waterproof and advantageously housed in the tension and drive drums 42 of this mat. The operation of the device which has just been described is indicated below because it makes it possible to put

  implementing a therapeutic rehabilitation process.

  A first known use of this device consists in adjusting the depth of water as a function of the size of the individual, in particular if it is a child. This is advantageous for learning to

swimming for example.

  Another known use, also preserved with this device, is the progressive launching

  of a person as he becomes accustomed

mance and its aquaticity.

  The new possibilities of rehabilitation that

  cure the original combination of a basin with an artificial current and a movable floor, are

many.

  If we refer to Figures 6 A and 6 B, we can better

understand these possibilities.

  In FIG. 6 A, the current flows over a height h with a force F compatible with the capacities

of this person.

  In this case, the floor is in the low position,

  giving the basin its maximum water height.

  The person is submerged, so that his weight is an apparent weight, that is to say the weight of the

  person diminished by Archimedes' thrust.

  Given the strength of the current, the person is

  forced to bend over to resist what makes tra

  valuing certain elements of the body.

  During this stage the person does not feel the

  body weight, which frees it to work

to be specific.

  In addition, it can be seen that the current exerts its action up to the upper part of the bust,

  all in the case of a laminar current, which lo-

  properly balances the person's reaction efforts.

  During the same exercise, the floor can be

  high so as to modify, on the one hand the point of im-

  1 O pact of the current and on the other hand to transfer the

  resistant efforts of the person in efforts of re-

taking his own weight.

  The method also provides for placing the person of

  face but also to orient it with respect to the di-

  rection of the current so as to make work

simulate all areas of the body.

  This was impossible beforehand Indeed alone

  walking allowed people to work

  sounds submerged This posed a problem when the joints were not functioning properly

for example.

  In addition it was impossible to make the back muscles work with a resistant effort because walking backwards is difficult to conceive and in all

  the efforts made are not enough

  fisantes. The possibilities and variations of exercises are multiplied by the accessories available such as the guardrails or the moving mat whether in the

  part of rehabilitation or sports training

tif.
