[0002] In alternative medicine, it is known to apply small magnets to a user's body in order to create a magnetic field. These magnets are said to be used, in particular, to treat joint or muscle pain, for example.

[0003] However, if these magnets are simply placed on the body, this assumes that the patient does not move unless the magnets fall. If these magnets are held on the body, for example by straps or elastic bands, this implies a tedious manipulation of each magnet to be positioned.

[0004] Finally, it is not possible to position excessively large magnets on the human body due to reasons of weight and bulk. Description of the invention

[0005] One object of the invention is therefore to propose a magnetotherapy installation, which allows a static magnetic field to be applied to a user, in particular when the latter is in a horizontal position (lying down), without the user having to bear the weight of the magnets and in such a way that the user can move during the application of this magnetic field.

[0006] Another object of the invention is to provide an installation which can be easily adapted for use by different users, and which in particular allows this magnetic field to be applied at different points on the body from one user to another.

All the permanent magnets of the frame are fixed so that their respective north poles are oriented towards the top of the frame, and all the permanent magnets of the arch are fixed so that their respective south poles are oriented downwards, or vice versa, so that the magnets of the arch create a magnetic field with the magnets of the frame. The trolley and the frame are equipped of a device for moving said trolley in longitudinal translation relative to said frame and the trolley and the vault are equipped with a device for moving the vault in vertical translation relative to said trolley.

[0009] Thanks to these features of the invention, the user of the installation can easily position themselves on the frame, and then the trolley carrying the vault equipped with magnets can be moved longitudinally and vertically to bring this vault over the area of ​​the user's body that is to be subjected to the magnetic field for the desired duration.

[0060] By referring to [Fig.1], one can see a magnetotherapy installation 1 according to the invention.

[0061] In the following description and claims, the terms "vertical", "horizontal", "upper", "lower", "top" and "bottom" are to be taken into consideration with respect to the normal operating position of the magnetotherapy installation 1, which is that shown in [Fig. 1].

[0062] This installation 1 comprises a frame 2 and a trolley 3, mobile in two dimensions, relative to this frame 2.

[0063] The frame 2 has a longitudinal axis X-X'. It comprises a fixed chassis 21 and a mattress 22, positioned on this chassis, the chassis 21 and the mattress 22 being configured and dimensioned to accommodate a user in a supine position. Thus, the frame 2 is fixed.

[0064] As can be seen in [Fig.2], the frame 21 comprises a platform 210, equipped with legs 211 for supporting this platform. The platform 210 is rectangular.

[0065] Several permanent magnets 23 are fixed to the chassis apron 210. In the embodiment shown in [Fig. 2], the apron 210 is a perforated plate and each magnet is fitted with a threaded rod. The magnets are fixed under the perforated plate so that their threaded rod passes through one of the holes in the perforated plate and protrudes from the upper surface of the plate, and a bolt is screwed onto the threaded rod, thus securing the magnet in place.

[0066] The magnets 23 of the frame could however be fixed in other ways.

[0067] Preferably, these magnets 23 are neodymium magnets. Preferably also These magnets are cylindrical and their magnetization is axial (north pole at one end of the cylinder and south pole at the other end). Preferably, these magnets have an outer diameter of 62 mm, an inner diameter of 6 mm, and a height of 35 mm, these measurements being given plus or minus 0.1 mm.

[0068] The magnets 23 preferably have a strength between 0.38 and 0.40 Tesla, and more preferably each magnet 23 has a strength of 0.4 Tesla (4000 Gauss). All the magnets 23 are fixed so that their respective north poles are oriented towards the top of the frame 2. Their respective south poles are therefore oriented towards the ground on which the frame rests. The reverse is also possible (all the south poles towards the top of the frame).

[0069] Preferably, the magnets 23 are arranged along several axial lines 230 (that is to say (i.e., parallel to the X-X' axis) and parallel to each other. Preferably, the magnets 23 are also arranged in several transverse rows 231 perpendicular to the X-X' axis. This makes it possible to create a regular and constant magnetic field, aligned with the body of the user lying on the frame 2.

[0070] Preferably, the center distance A (measured from center to center) between two magnets 23 in the axial direction (parallel to X-X') is between 130 mm and 150 mm, preferably even more is equal to 140 mm.

[0071] Preferably, the center distance B between two magnets 23 in the transverse direction (perpendicular to X-X') is between 95 mm and 115 mm, preferably even more is equal to 105 mm.

[0072] Furthermore, as can be seen in figures 7 to 10, the carriage 3 and the frame 2 are equipped with a longitudinal translation displacement device 4 of said carriage 3 relative to said frame 2. By "longitudinal translation", we mean a translation along the axis X-X'.

[0073] The longitudinal translation displacement device 4 includes a guide device 41 of the carriage 3 relative to the frame 2 and an actuation device 42 of the carriage enabling the movement of the latter.

[0074] The guide device 41 comprises at least one guide rail 410, fixed to the frame 2 parallel to its longitudinal axis X-X'. Preferably, this rail 410 is fixed along one of the longitudinal edges of the frame 21 of the frame 2. Even more preferably, and as can be seen in [Fig. 2], the device 41 comprises two guide rails 410, fixed respectively along each longitudinal edge of the frame 21. The role of this rail (these rails) will be described later.

[0075] In addition, preferably, the apron 210 is slightly inclined with respect to the horizontal, as seen in the figures and has an upper end 212 and a lower end 213, and to do this, the feet 211 located at the upper end are longer than those located at the lower end.

[0076] According to the embodiment shown in [Fig.3], the trolley 3 preferably comprises a vertical frame 30 and an assembled bracket 31.

[0077] The vertical frame 30 consists of two parallel vertical uprights 301, connected by two horizontal and axial longitudinal members 302 (i.e., extending parallel to the axis X-X' when the carriage 3 is mounted on the frame 2).

[0078] The bracket 31 comprises two horizontal cross members 311, connected to each other at one of their ends by a horizontal axial stringer 312. Each of the two horizontal cross members 311 is further fixed by its free end (those not connected to the stringer 312) to one of the uprights 301. In addition, on each side of the bracket, an inclined bar 313 is fixed between a mid-portion of the cross member 311 and the lower end of the upright 301 so as to resist the forces.

[0079] The carriage 3 further includes at least one pair of rollers 411 which are part of the guide device 41. These rollers can be single or double wheel as shown in the figures.

[0080] In the embodiment shown in the figures, the carriage 3 comprises two pairs of rollers 411, the first pair comprising two rollers fixed respectively on each cross member 311, near the frame 30 and the second pair comprising two rollers fixed respectively at the angle between each cross member 311 and the longitudinal member 312.

[0081] Each pair of roller bearings 411 is received in a guide rail 410, so that each roller bearing 411 can slide inside this rail 410 (see figures 7 to 10).

[0082] As can be seen in these same figures, the actuation device 42 of the carriage 3 comprises a drive belt 420 and a rotating drum 421. One end of the belt 420 is fixed to the upper end 212 of the frame 2 and the other end is fixed to the rotating drum 421.

[0083] The rotating drum 421 is driven in rotation in one direction or the opposite direction by a motor 422, preferably electric. The rotating drum 421 is fixed to the carriage 3, preferably to its vertical frame 30.

[0084] The carriage 3 supports an arch 5, visible in figures 1, 5 and 6.

[0085] The vault 5 includes a curved support plate 51, shaped like a portion of cylinder, with longitudinal axis Xl-X' 1, (see figures 5 and 6).

[0086] Several permanent magnets 52 are fixed to its concave face 510.

[0087] Preferably, these magnets 52 are neodymium magnets. Preferably also, these magnets are cylindrical and their magnetization is axial (north pole at one end of the cylinder and south pole at the other end of the cylinder). Preferably, these magnets have an outside diameter of 72 mm and a height of 37 mm, these measurements being given plus or minus 0.1 mm.

[0088] The magnets 52 preferably have a power between 0.38 and 0.40 Tesla, preferably each magnet 23 has a power of 0.4 Tesla (4000 Gauss).

[0089] Preferably, they are aligned in the form of several axial lines 520 (parallel to the axis Xl-X' 1). Also preferably, the magnets 52 are arranged in several transverse rows 521 perpendicular to the axis X-X'.

[0090] Preferably, the center distance C between two magnets 52 in the axial direction (parallel to Xl-X' 1) is between 130 mm and 150 mm, preferably even more is equal to 140 mm.

[0091] Preferably, the center distance D between two magnets 52 in the transverse direction (perpendicular to X-X') is between 95 mm and 115 mm, preferably even more is equal to 105 mm.

[0092] In the embodiment shown in Figures 5 and 6, the support plate 51 is perforated with perforations 511 and each magnet 52 is fitted with a threaded rod. The magnets 52 are fixed to the perforated plate 51, such that their threaded rod passes through one of the perforations 511 and protrudes from the convex face of the plate 51, and a bolt is screwed onto the threaded rod, thus securing the magnet 52.

[0093] The magnets 52 could however be fixed in other ways.

[0094] All the magnets 52 are fixed so that their respective south poles are oriented downwards (towards the ground), when all the magnets 23 are fixed so that their respective north poles are oriented towards the top of the frame 2. The reverse is also possible (north poles of all the magnets 52 oriented downwards and south poles of all the magnets 23 oriented towards the top of the frame 2).

[0095] Preferably, the magnetic field thus created between the frame 2 and the vault 5 is between 0.010 Tesla and 0.015 Tesla, preferably even more is equal to 0.012 Tesla (120 Gauss).

[0096] In figures 1 and 6, it can be seen that the vault 5 is fixed to the upper part of a vertical support frame 53, so that its longitudinal axis Xl-X'l is slightly inclined with respect to the horizontal.

[0097] By referring to figures 4 and 6, it can be seen that the frame 53 is formed of two parallel vertical uprights 531, connected by two horizontal and axial longitudinal members 532.

[0098] Furthermore, as can be seen in figures 3, 4 and 6, the carriage 3 and the vault 5 are equipped with a vertical translation displacement device 6 of said vault 5 relative to said carriage 3.

[0099] The vertical translation displacement device 6 includes a guide device 61 of the vault 5 relative to the carriage 3 and an actuation device 62 of the vault enabling the vertical displacement of the latter.

[0100] In the embodiment shown in the figures, the guide device 61 of the vault 5 comprises at least two guide bars 611, each of them cooperating with at least one guide bearing 612.

[0101] In [Fig.3], it can be seen that the two guide bars 611 are fixed to the frame 30 of the carriage 3, preferably on the two longitudinal members 302. These guide bars 611 extend vertically.

[0102] In figures 4 and 6, it can be seen that each vertical upright 531 of the frame 53 is provided with at least one guide bearing 612 with a vertical central axis, preferably with two superimposed and coaxial guide bearings 612.

[0103] The frame 53 is assembled to the carriage 3 so that each guide bar 611 is received in a guide bearing 612, here in two superimposed bearings 612, which allows the vertical sliding of the frame 53 and therefore of the arch 5 relative to the carriage 3.

[0104] Although not shown, the reverse is also conceivable, i.e. that the guide bars 611 can be fixed on the frame 53 and be integral with the arch 5 and the guide bearings 612 can be fixed on the carriage 3.

[0105] The actuation device 62 of the arch is preferably at least one cylinder, such as an electric, hydraulic, or pneumatic cylinder, more preferably at least one electric cylinder. Said at least one cylinder 62 comprises a body 621 and a rod 622. Advantageously, the actuation device 62 of the arch is formed by 24V electric cylinders.

[0106] In the embodiment shown in Figures 3 and 4, the cylinder body 621 is fixed vertically to the frame 30, preferably between the two uprights 301 and on the lower longitudinal member 302, and the rod 622 of the cylinder 62 is fixed vertically to the frame 53, preferably between the two uprights 531 and on the upper longitudinal member 532. The reverse is also possible.

[0107] The actuation of the cylinder 62 causes the vertical displacement of the frame 53 and therefore of the arch 5 relative to the carriage 3, in the direction of the ascent or descent.

[0108] When the carriage 3 is mounted on the frame 2, it is positioned so that the arch 5 is located above this frame 2 and the concave face 510 of the arch is oriented towards this frame (see [Fig. 1]). The permanent magnets 23 of the frame create a magnetic field with the permanent magnets 52 of the arch.

One permanent magnet 71 is opposite each heel of the user, and one permanent magnet 71 is opposite the end portion of each foot of the user.

[0118] Preferably, the four permanent magnets 71 fixed on the first auxiliary plate 73 are arranged on the same plane orthogonal to their north poles and are further arranged in pairs, the permanent magnets 71 of each pair being arranged symmetrically with respect to a vertical plane comprising the longitudinal axis X-X' of the frame, and preferably having their north poles oriented in opposite directions.

[0159] The user who is to be subjected to the magnetic field is installed on the frame 2, preferably so that his head is located at the upper end 212.

[0160] The central unit 7 enables the movement of the carriage 3 as follows. Starting from the lower position in [Fig. 8], the central unit 7 drives the motor 422, which rotates the drum 421. As it does so, the drive belt 420 wraps around the drum 421, and since its other end is held at the upper end 212 of the frame 2, the carriage 3 moves towards the upper end 212 (to the right in Figures 8 to 10). Conversely, the rotation of the drum 421 in the opposite direction, coupled with the weight of the carriage, causes it to move towards the lower end 213 (to the left in Figures 8 to 10). The carriage 3 can thus be positioned precisely above the part of the user's body to be treated.

[0161] Furthermore, the central unit 7 allows the vertical movement of the vault 5 by the actuation of the cylinder 62, until the vault 5 and therefore the magnets 52 that it supports are at the correct distance from the user and the magnets 23.

[0162] Advantageously, a vertical limit switch 8 can be attached to the arch 5 (see [Fig. 1]) to detect the presence of the user and stop the vertical movement of the arch 5 before it gets too close to the user. This vertical limit switch 8 is also connected to the central unit 7 to send it the information. Preferably, such a sensor is a laser distance sensor.

[0163] Advantageously, the installation can also be equipped with two axial limit switches 9 for the carriage 3 relative to the frame 2 (see [Fig. 7]). Such sensors 9 are, for example, inductive sensors. One sensor 9 is placed on each side of the carriage 3. The carriage 3 stops when the sensor encounters the limit switch. inductive 9 with a metal tab 91 fixed to each end of the frame 2.

[0164] Installation 1 allows a static magnetic field to be applied to a user, which could have a beneficial effect on certain conditions, including multiple sclerosis, osteoarthritis, tendinitis, osteoporosis, the relief of certain pains and the improvement of wound healing.
