l

The present invention relates to a gymnastic and rehabilitation apparatus which uses the principle of braking by direct magnetic resistance to stress all the parts of the body at the same time.

Braking by direct magnetic resistance of a mobile element provided with magnetic means which moves on a metallic surface is the braking of this mobile element by its own magnetic means which apply this mobile element on the metallic surface and so that this braking is done silently smoothly and without vibration the friction surfaces which are in contact, which concern on the one hand the movable element provided with its magnetic means and on the other hand the metallic surface, are covered with a material which promotes the sliding of the mobile element on the metal surface which material meets the standards of tribology (which is the science of friction) so that this sliding is optimal.

Claim 7 of patent FR 1300148 presents the basic concept of an analytical type device which works an upper limb or a lower limb and which operates according to the principle of braking by direct magnetic resistance. This device consists in sliding with his hand or his foot a mobile element provided with magnets on a metallic surface positioned vertically. The contact face of the second braking part which allows the magnets to be flush with the metal surface is covered with a material which ensures the sliding of the movable element on the metal surface like a polyester fabric for the contact face and a pvc sheet for the metal surface, but this device of claim 7 of patent FR 1300148 malfunctions for four reasons:

The mobile element is multidirectional unlike the other devices of this patent and this multidirectional movement imposes on the second braking part and on its contact face abrupt changes of direction which strike and therefore wear the sliding materials.

- The non-fixity of the second braking part which slides in the body of the movable element (box 20 b) causes lateral play of this second braking part and its contact face which also irritates the sliding materials. .

- The vibrations and detachments of 1 moving element require 1 assistance from

1 ’other hand to properly apply 1’ moving element to the metal surface.

- The work of the lower limb is tedious

This analytical device, which is intended for a single upper limb or a single lower limb, therefore has no place in a rehabilitation room or a gym.

We can see that the only way to slide smoothly and smoothly, without detachment and without vibration mobile mobile element on the metal surface, is to grasp this mobile element with both hands and move it on the metal surface with all upper body, but this metal surface is unsuitable and the movable member is subjected to even more aggressive movements which tend to eat away at the sliding material which covers its contact face and to scratch the underlying sliding material which covers the metal surface. This aggressiveness of the movable element on these sliding materials is due on the one hand to the multidirectional movement of the movable element and to the lateral play of the contact face of the movable element and on the other hand to the hardness of the material. of the contact face of one movable element and the roughness of this contact face. These asperities are found in the angles of this contact face, when it is for example square or hexagonal, or in 1 ’angle of its periphery when it is delimited at right angles, etc.

The present invention relates to a gymnastic apparatus which follows from the preceding observations, namely that the sliding of the movable element on the metal surface can only be done with the two upper limbs on a suitable metal surface and this sliding must be the least aggressive possible for the sliding materials which cover the contact face of the movable element and the metal surface. For this reason this gymnastic and reeducation apparatus is characterized in that it is essentially intended for the direct work of the two upper limbs and therefore relates to both the mobile element whose characteristics are to reduce the aggressiveness of the contact face and the metal surface whose characteristics are to promote specific or overall work of the body:

The moving element: The contact face which allows the magnets to be flush must be as less aggressive as possible for the sliding materials underlying the moving element and the metal surface. For this reason, whatever the magnetization system put in place to apply 1 movable element to the metal surface, the contact face of 1 movable element meets at least three characteristics:

- The contact face is preferably fixed to the body of 1 mobile element to avoid any lateral play of this contact face and this fixing can be done by screw or by a tenon / mortise assembly.

- The roughness formed by the angles of this contact face must be reduced to the maximum: this contact face is preferably circular, its periphery is rounded or biased. Similarly, the magnets are preferably circular and are housed in circular wells whose upper periphery is rounded or biased.

- The contact face can be made of a material which is both flexible and incompressible:

: Soft: to soften the contact of all the projecting parts of the contact face with the sliding materials underlying the contact face and the metal surface.

: Incompressible: to avoid the prominence of the magnets relative to the contact face when the contact face of the movable element slides on the metal surface and thus avoid this prominence of the magnets injuring the underlying sliding materials.

The material of the contact face may be different from the material of the rest of the movable element and may be made of rubber, felt, cork, silicone, leather, etc.

The metal surface: it is configured according to three characteristics so that the direct work of the upper limbs on the metal surface leads to the indirect work of the trunk and of the two lower limbs, that is to say without effective participation of the two lower limbs on the metal surface:

- It can be delimited in order to impose a defined path on 1 moving element. For example: the sun with its rays, a spiral, the eight elongated by Γ infinite.

- It can be perforated with tiny holes to reveal LED micro-bulbs connected to an electronic system which lights these bulbs in a defined direction and rhythm so as to impose on the mobile element a defined trajectory and cadence.

- It can be simply large enough to allow a subject to express himself freely by sliding the moving element in all directions without vertical and horizontal limitation.

For this bodybuilding machine to be very effective, it is necessary to reconsider the relationship between the movable element and the metal surface both at the level of the sliding of the movable element on the metallic surface to ensure the gripping with two hands of The movable element only at the level of the attraction force which exists between the magnets of the movable element and the metal surface.

The two-hand sliding of the movable element on the metal surface can be improved by enlarging the contact face of the movable element with the metal surface (this enlargement of the contact face of the movable element being a function of the support polygon of the resultant of the forces applied by the magnets on the metal surface), by the addition of a new handle which will further stabilize the mobile element on the metal surface and as we will see in another chapter the sliding of the mobile element on the metal surface is improved above all by the quality of the sliding materials which cover on the one hand the metal working surface and on the other hand the friction face of the mobile element with the metal surface which quality must meet the imperatives of tribology which is the science of friction

The attraction force of the magnets of the movable element by the metal surface can be improved by increasing the power of each magnet, by increasing their number, by increasing the thickness of the metal surface. but also and above all by varying the distance between the magnets and the metal surface, the theme of which will be dealt with in a particular chapter.

The quality of this gymnastic and rehabilitation device depends on the one hand on the quality of sliding between the mobile element and the metal working surface and on the other hand on the quality of the magnetic resistance between the mobile element and the surface. working metal which must be constant when a given subject slides this mobile element on the metal surface.

The quality of the sliding:

In order for the sliding of the movable element on the metallic surface to be of good quality, it can be seen that on the one hand, the sliding material which covers the metallic surface must be considered and, on the other hand, the sliding material which covers the area of contact of the movable element with the metal working surface, these two materials having to meet the requirements of tribology so that the movable element can slide as perfectly as possible on the metallic surface and as noisily as possible, that is to say without vibration and smoothly, without damage or scratching for sliding materials:

- The material which covers the metallic surface can be a very hard and very smooth coating which adheres to the metallic surface like a thermo-lacquered paint, vitrified enamel, an epoxy resin or even a melamine paint etc ...

This material which covers the metallic surface can be a material which is not adherent to the metallic surface and which is fixed on this metallic surface constituted by a rigid plastic sheet which resists abrasion such as polyethylene, pmma, formica , or some pvc etc ...

NB: pvc, pmma or any hard and transparent plastic material not only allow the mobile element to slide on the metal working surface but also offer the possibility of interposing between the metal surface and this transparent plastic sheet a poster , a photo, an exercise grid or even a thin tapestry, a painting etc ... Thus giving an aesthetic note to this bodybuilding and cardio - training device.

- The material which covers the contact area of the movable element with the metallic surface must respond as perfectly as possible to the laws of tribology so that the sliding of the movable element on the coating of the metallic surface occurs most naturally possible, that is to say without vibration, smoothly, without noise and without scratching.

So that the contact area of the movable element with the material which covers the metal surface is as less aggressive as possible, we can consider at least two elements which allow on the one hand a more flexible contact of the contact area of the movable element. with the material which covers the metallic surface and on the other hand a better sliding of this contact zone of one movable element on the material which covers the metallic surface.

So that the contact of the movable element with the material which covers the metal surface is less hard and therefore less aggressive, it is possible to ensure, as it is written above, that the lower part of the movable element which allows the magnets is made of a more flexible material such as cork, leather, polystyrene, rubber, silicone etc.

To improve the sliding of the contact zone of the movable element with the material which covers the metallic surface, it is possible to cover this contact zone with a material which corresponds to tribology (which is the science of friction) and which is compatible. with the material which covers the metal surface, this material being able to be a flexible and nevertheless very resistant fabric such as polyester, nylon, or polyamide etc ...

The quality of the magnetic resistance:

The effort and therefore the braking produced during the sliding of the mobile element on the metal working surface is caused by the magnets or any magnetized means which may be under the mobile element and more particularly in the contact zone of 1 movable element with the metallic surface, which magnets or magnetized means oppose Γ projection of Γ movable element on the metallic surface.

To vary the force produced during the sliding of the mobile element on the metal surface, one can play on many factors including the thickness of the metal of the metal surface, the attraction of which by the magnets is proportional to its thickness, on the more or less power of the magnets, on the number of magnets, one can also vary the force of attraction of the magnets by the metal of the metallic surface which is function of the distance which separates the magnets from the metal. To vary the distance which separates the magnets from the movable element of the metal from the metal working surface, all the mechanical means are used which bring the magnets closer or further away from the metal surface, these means possibly being constituted by a system of screws or slide which nevertheless reveals an air cushion very detrimental to magnetization between the magnets and the metal of the metal surface, or a system of shims interposed between the magnets and the metal surface as described in patent FR number 1300148 which removes the air cushion that exists between the magnets and the metal surface, which removal of air cushion greatly promotes magnetization. This distance can be varied by covering the contact face of the movable element (that which allows the magnets to be flush) with a sliding material of different thicknesses, etc.

The metal working surface of this gymnastic and rehabilitation device which is intended for the two upper limbs can possibly allow analytical work of each lower limb but above all to adjust to the size of a small or large subject thanks to mechanical means which make it possible to vary the height of this work surface such as a counterweight system which opposes the weight of the apparatus by means of a rope which slides in a pulley, or also a gear wheel system linked to the work surface that is raised or lowered on a rack with a crank etc ...

According to the different embodiments:

The usual way to use this direct magnetic resistance weight training machine intended for the direct work of the two upper limbs and for the indirect work of the trunk and the upper limbs is to move the metal work surface on a wall or on any vertical plane well anchored to the ground, to place the base of the apparatus at the mid-thigh of a subject of average size and to take care that it is of a sufficiently important dimension as well in width as in height for that a given subject placed in the middle of the device can grasp the movable element with his two hands and express himself completely by sliding it on the metal surface according to the configurations of this metal surface:

This metallic surface can take variable forms depending on the boundaries or not which are given to this metallic surface:

This metal surface can be delimited in several nonlimiting ways and these delimitations will determine the trajectory of the mobile element and specifically solicit the body:

- It can have the shape of a sun with its rays (or of a flower with its petals, or of a star with its branches) and a given subject realizes a movement in star by sliding 1 movable element starting from center of the sun toward the end of each of its rays in a back and forth motion. These devices which allow a movement in star also present an economic advantage because the metal working surface is made up of various parts during its assembly - for example the central and circular part of the sun can be represented by a circle which adjoins the rays of the sun. which are represented by rectangles and if only one part of the metal working surface is damaged we can change only this part and not the whole surface as would be the case for a device whose surface would be one holding, square or circular for example, and which also allows a star movement from the center.

- This metallic work surface can have the shape of a spiral which invites the subject to slide the mobile element from the periphery towards the center and vice versa.

- This metallic surface can have the shape of an elongated eight reproducing in this the Greek letter Omega on which a subject slides the movable element to thus achieve an excellent movement which solicits the body as a whole and improves laterality disorders as in children than in adults.

The metal working surface can be free of any particular delimitation and have a classic shape: it can be circular, square or rectangular so that a subject can grasp the movable element with two hands and slide it over the metal surface locally according to small kineses and especially as far as possible according to large kineses by making him describe infinite movements such as letters, numbers, horizontal or vertical hatching, circles which become larger and larger, or even movements in a star by sliding the movable element in all directions from the center.

This last classic form of the metal work surface can be perforated by a system of small holes which reveal tiny LED bulbs which are connected to a computer system which allows the lighting of these bulbs according to a circuit and a speed defined at 1 'advance in order to propose to a subject the exercise to be carried out and its cadence.

The metal working surface, whether it is specifically delimited or devoid of any delimitation, is preferably positioned on a vertical plane but can be tilted degree by degree from the vertical position to the horizontal position.

The metal working surface of this gymnastic apparatus can therefore be delimited in a specific way or quite simply have a classic shape and the dimensions of this metal working surface depend on the size of the subject who slides the movable element with its two hands as far as possible on the metal surface and we can consider that for a subject of lm60 the dimension of the working surface can be a square of lm50 on the side or a circle of lm50 in diameter and for a subject of lm90 the dimension of the work surface can be a square of 2.50 m on a side or a circle of 2.50 m in diameter or even beyond.

The accompanying drawings illustrate the invention:

FIG. 1 shows a sagittal section of the assembly composed by the movable element 1a and the metal surface (12) and more particularly the constituent parts of the movable element (la), which are the body of the movable element ( 2), the body (4) which constitutes the contact face (5) and which is fixed to the body (2) by a tenon / mortise assembly (4 '), the magnets (7) and the shim system (14) which allows to vary

3064928 the distance between the magnets (7) from the metal surface (12), the sliding material (8) which covers this contact face (5), and the handle (9) of the movable element (la).

The moving element:

The contact face (5) itself:

- The delimitation (3) between the body (2) of the movable element and the body (4) of the contact face (5) suggests that the body (4) and therefore the contact face (5) are of a different material with respect to the body (2) of the movable element. This material is both flexible and incompressible and can be rubber, cork, leather, etc.

- The periphery (6) of this contact face (5) is rounded as well as the periphery (6) of the well (7a) in which the magnets (7) are located so as not to damage the sliding material first of all (8) of the contact face (5) and then the sliding material (13) of the metal surface (12).

Magnets (7):

They are preferably circular and are contained in a circular well (7a) whose upper periphery (6) is rounded or biased so as not to damage the coating materials of the mobile element (5) and of the metal surface (12). . Likewise, the upper face of these magnets (7) is just below (a few microns) from the contact face (5) in order to avoid the prominence of these magnets which also risks damaging the underlying coating materials. .

The sliding material (8):

- It can be flexible and very resistant at the same time and allows the sliding of the contact face (5) on the coating (13) of the metal surface (12) and this flexible and resistant material (8) can be represented by a polyamide, nylon or polyester fabric etc ...

The handle (9) and the body (2) of mobile mobile element:

They can be designed in the same block or be independent of each other (by a fitting, clipping, screwing (10) or other system) and must resist the sudden movements imposed on the movable element by its user.

The metal surface (12):

It consists of a metal plate which attracts magnets such as steel and this metal plate is coated with a material (13) which promotes the sliding of the movable element (la) on this metal surface (12) . The material (13) which covers the metal plate (12) can be non-adherent or adherent to this metal plate: in the first case it can be constituted by a plastic sheet of the pvc or polyethylene style and in the second case it can be constituted by a thermo-lacquered paint or a resin etc.

Figure 2 shows a bottom view of one movable element (la) which is constituted by the contact face (5) which is preferably circular and the wells (7a) which are also circular and in which the magnets are housed (7). The delineation in dotted line (6) of the circumference of the contact face (5) and of the wells (7a) in which the magnet (7) mark Γ is rounded which allows to reduce the roughness of the contact face which does not must not strike or irritate its own coating material (8) and the coating material (13) of the metal surface (12).

Figure 3 shows three examples, certainly not limiting, of movable elements (la) each provided with a means which makes it possible to adjust the intensity of the attraction of the magnets (7) of the movable element (la) metallic surface (12) by varying the distance which separates the magnets (7) from this metallic surface (12) and these three examples are constituted by:

- A coating (8) of different thicknesses on the contact face (5) .Fig 3a

- A system of shims (14) of different thicknesses. Fig 3b

- A system of screws (15) or slides etc. Fig 3c.

Figure 4 shows the metal surface (12) in common use: here it is square, positioned on a vertical plane, the base of this metal surface is raised and is located approximately at the mid-thigh of a medium-sized subject while the height is determined according to the highest point that the subject can touch with his hand and the width by the most lateral point that he can touch with his left hand and with his right hand. Figure 4 shows a subject which is in the middle of the metal surface and which causes the movable element to form a large circle by sliding it over the metal surface:

Figure 4a shows the subject when in extreme extension standing on tiptoe, Figure 4b shows the subject when it is in maximum lateral extension and Figure 4c shows the subject when it is in maximum flexion with the back straight. These three figures show the indirect but total participation of the two lower limbs and the trunk.

he

FIG. 5 shows some of the infinite delimitation possibilities that can be given to the metal surface in order to impose a defined trajectory on the movable element which trajectory will stress the body in a particular way: we therefore see that this surface can take the form of a sun with its rays (16) of a spiral (17) or of an elongated figure eight (18) etc ...

FIG. 6 shows the infinite possibilities of movement offered by the sliding of the mobile element on a metallic surface (12) sufficiently large to allow for example to draw the elongated eight of the infinity (18) of the letters (19) of the numbers (20), horizontal and vertical hatching (21) and above all the star movement (22) which consists in pushing the movable element in all directions from the center and which stresses the body remarkably.

FIG. 7 shows a metal surface (12) perforated with tiny holes revealing tiny bulbs (23) of the LED style which light up to give a trajectory (24) to the mobile element and thus define the exercise to be executed, and the speed of light of which determines the speed of execution of the exercise.

FIG. 8 shows the apparatus whose weight of the metal working surface (12) on which the movable element is slid is counterbalanced by a counterweight system (25) which opposes the weight of the surface metal (12) Γ through a rope (26) which slides in a pulley (27).

As has been said previously, this weight training machine uses the principle of direct magnetic braking and consists in taking with the two hands the handle (9) of a mobile element (la) provided with magnetic means (7) to slide it on a metal surface (12) adapted with the whole of its body, that is to say with the participation of the trunk and of the lower limbs. The contact face (5) of the movable element (la) must not attack the coating materials (8) and (13) of the contact face (5) itself and of the metal surface (12) and for this reason the body (4) of this contact face (5) is above all fixed to the body (2) of the movable element (la) by a system of screws or tenons / mortises to avoid any lateral play, its angles are rounded (6) to eliminate all kinds of roughness and it is made of a flexible and incompressible material at the same time. The contact face (5) of the movable element (la) and the metal surface (12) are therefore both covered with a material (8) and (13) which promotes the sliding of the movable element (the ) on the metal surface.

This gymnastics and rehabilitation device alone fulfills several qualities: it is very efficient, compact, has a real aesthetic and above all its cost price is particularly low since it is easily constructed with very simple.
