Description

Portable and modular device forming a support support for osteo-articular postures

The present invention relates to an extended support device, its manufacturing methods and configuration of use. The support device is intended to support a portion of a user's body during STATCAL postures of osteo-articular corrections and musculo-aponeurotic stretching, in particular concerning deformities of the ankle and foot and consequently the release of associated circulatory venous disorders, or concerning deformations of heads of newborns.

The present invention also relates to a prolonged support device for static postures of osteo-articular correction and musculo-aponeurotic stretching making it possible to correct from the first age certain deformations of the head of newborns such as in particular: plagiocephaly, brachycephaly and congenital torticollis.

A static support device for the foot is described for example in the document EPI 115460, which describes an altuglas device whose design allows the posture of the ankle and the foot and aims to improve the return circulation. This device is equipped with additional altuglas equipment to vary the angle as well as a hemisphere placed under the heel of the device allowing it to tilt sideways. Π is fitted with additional flexible rubber equipment to absorb the load. The device is uncomfortable, unstable, expensive, complicated to manufacture and position.

Cranial orthoses are described for example in documents WO 2005009277, W02010096727, WO98 / 36712, WO 2008/022304, or

W02017042550.

These documents describe orthotics in the form of a shell, enveloping the head and whose internal correction geometry is difficult to grasp and to control once the shell is placed around the head. These orthoses are also uncomfortable and anxiety-provoking for the wearer.

In order to improve comfort and reduce costs, the invention proposes to use open, modular and flexible support systems.

Research on flexible or soft support devices did not reveal any device suitable for the static correction postures targeted by the invention. So :

1 °) The document JPH105257A of 13.1.98, shows a set of modules adaptable in chiropractic, serving as a postural pillow intended to reduce the contractures of the muscles of the neck. Π can be used as a chair or a ventral cushion.

2 °) Document JP2004223082A of 12.8.2004, describes a cushion intended only for wheelchairs or cars, of comfort, capable of adapting the pelvis and the spinal column in a seated position or constraining certain postures of the back in supine position.

3 °) The document EP1609509A1 of 28.12.05 describes a physical exercise mat formed by the assembly of modules of different shapes and sizes used in gymnastics or as a landing mat. This device involves the manufacture of a covering of protection and fixing means for high mechanical stresses.

4 °) The document EP2599527A1 of 5.6.2013 describes modules or associations of triangular prismatic modules in fully expanded polyurethane, which can be provided with an additional coating, the strictly dynamic purpose of which is to work the muscles of the body in catching up with the imbalance caused by these modules The user must constantly contract to find his balance

5 °) The document US2009 / 192028A1 of 30.7.2009 shows a system of wedges and assembly of comfort wedges, complementary to the exercise of yoga or those of Fitness in flexible foam with closed cells with adhesives or other intermediate material separating the different layers. This complex device provides intermediate cushioning layers and fasteners. It is complicated to manufacture.

6 °) Document JP2000 079135A of 21.3.2000 shows a seat cushion, lumbar correction in bar and wedge-shaped. These devices have the disadvantages of being subject to a multiplicity of sizes and shapes, of providing intermediate cushioning layers, of being limited only to lumbar adaptations and to sitting postures.

7 °) Document WO 2008 087594 shows a fitness and therapy mat made of polyurethane with open cells, which is required to increase instability so that the user, unbalanced, contracts and works his muscles to retain himself.

None of these seven flexible devices in is adapted, by its design for vertical postures of passive stretching concerning in particular the deformations of the foot and the head.

The object of the invention is to propose a support device which is inexpensive, comfortable because it is open and flexible, adaptable according to the user and the posture sought, making it possible to support a foot or a head during passive postures, by example in vertical postures for the foot or horizontal postures for the head, postures that use body weight to reduce deformation of the foot, head, or other area of the body concerned.

To this end, the invention provides a support device for osteo-articular postures or muscle stretching, comprising at least two identical prismatic modules forming support wedges for static postures, each prismatic module defining an elastically compressible cushion (by elastically compressible it is understood that the module returns to its rest form in the absence of stress, even if the return to the rest geometry is not instantaneous) said prismatic module being, in the absence of mechanical stress, delimited by:

a first base support lace and a second inclined support face, of substantially equal surface areas, said support faces being rectangular or square, the base support face and the inclined support face meeting in a first edge of the prismatic module, forming an angle of inclination between them,

a third face forming a rectangular lateral face, with a surface strictly less than 1/3 of the surface of the first and 1/3 of the surface of the second bearing face, the third rectangular surface connecting the two bearing faces , and defining a thickness at rest of the module,

a fourth lateral face, and a fifth lateral face opposite to the fourth face, the fourth and the fifth lateral face forming together two triangular bases (for example in the form of isosceles triangles or in the form of right triangle) of the prismatic module, the fourth face and the fifth face each being substantially perpendicular to the two support feces and to the third rectangular face (by substantially perpendicular is meant forming an angle between 80 ° and 100 °).

Each module comprises, defining the bulk of the volume of the prismatic module, a prismatic block of foam produced in a single piece of closed-cell elastomer foam.

The modules are configured so that they can be stacked one on top of the other in various positions, by total or partial contact of a support plate of one module with one or more support plates of one or more other modules , so as to form a support device capable of supporting, in this stacked configuration, without other support than the other modules and a lower horizontal support, a static pressure of a foot, a head or a another portion of the body of a user, the device then comprising in the position of use, at least one stack or a juxtaposition of two stacks of said prismatic modules.

In all of the text, it is considered that two areas are substantially equal if their areas differ by less than 10% in relative value with respect to the largest area.

The device can comprise between 4 and 8 prismatic modules, for example 5 prismatic modules, or more advantageously to optimize both the storage and the variety of use of the device, can include 6 identical prismatic modules.

Preferably, the surfaces of the support faeces of two separate modules differ by less than 15% two by two, advantageously by less than 10% two by two.

Preferably the angles of inclination of two modules of the device differ by less than 15% in pairs, advantageously by less than 5% in pairs.

The coefficient of friction, between the support feces applied one against the other at room temperature (20 ° C) is such that: two modules stacked by the entirety of one of their respective support feces, so that the stack has a horizontal upper fece, the modules being compressed by a vertical distributed force of ION, are prevented from sliding relative to each other under the effect of a horizontal tangential force parallel to the first edges of the modules prismatic, at least up to a tangential force of 15N, preferably at least up to a tangential force of 20N.

The elastomer may for example be of the closed-cell polyurethane type, or may be of the closed-cell EPDM (ethylene-propylene-diene monomer) type, or may be another foamed polymer, preferably with closed cells. By closed cells is meant that the structure of the elastomer has in its mass hollow areas containing bubbles of trapped gas, the contours of these hollow areas each essentially forming a closed cell.

The closed-cell structure allows firmer support for the limb or head (thanks to the elastic air trapped in the cells), and faster elastic return behavior when the mechanical stresses applied to or removed are varied. module. Particularly advantageously, the modules can be made only of foamed elastomeric material, which reduces manufacturing costs. Manufacturing costs are further reduced if all the modules are simply removed by slicing from the same block of foamed elastomeric material. In addition, such a module is durable, because in the event of deterioration of its surface state or surface stain, it suffices to abrade / cut a surface layer of the material to find a module with a surface state close to that initial.

The prismatic shape of the modules can be obtained by cutting a larger block of foamed material. The cutting process (for example a cutting process by slicing) can be chosen such that at the cutting planes, the surfaces of the modules then have micro-reliefs corresponding to the wells formed by the cutting of the cells filled with air from the foamed material. This type of relief of the elastomeric material gives the modules, at the same time a good cleaning ability, a pleasant contact with the skin, and a coefficient of friction facilitating the anchoring of the assembled modules relative to each other, to prevent the upper modules do not slide for example with respect to lower modules.

According to a preferred embodiment, the device comprises a maximum of six perfectly identical modules. According to a first embodiment, the device only comprises six modules. The device can also comprise a rectangular storage container forming a box or storage cover with rectangular faces configured to contain in an adjusted fashion the six non-compressed stacked modules (or tablets of less than 5% of their volume at rest). The dimensions of the container can be for example 335 cm x 155 cm x 55 cm for a first embodiment, or neighboring dimensions differing by less than + -7 cm for each dimension mentioned. Such a compact and light device can be used to produce by stacking modules, typically up to 12 or more varieties of support stacks suitable for 12 different postural applications.

According to a second embodiment, the device comprises, in addition to a group of prismatic modules, a sole forming a mat of constant thickness, the sole being adapted to support at least two entire bearing faces of two modules facing each other by their first respective edges. The sole can advantageously include a thickness made of the same foamed elastomeric material as the prismatic modules. Advantageously, the sole can be produced only from foamed elastomer.

The device may further comprise a parallelepiped storage container forming a box or storage cover with rectangular faces configured to contain in an adjusted manner the prismatic modules and the stacked stack not compressed (or compressed of less than 5% of their volume at rest). The dimensions of the container can be for example 210 x 190 x 130 cm, with a margin of + -7 cm for each side compared to these typical dimensions. Such a compact and light device can be used to produce modules by stacking, in particular 3 varieties of support stacks adapted to 3 different postural applications.

According to a preferred embodiment, the fourth and fifth side surfaces form two symmetrical right triangles from each other. We choose, for these embodiments, to designate by inclined bearing face the bearing face along the longest side of the right triangle, the other bearing face being designated by base bearing face. This configuration makes it easier to manufacture the modules and optimize the consumption of the material used for the modules.

According to a particularly advantageous embodiment, at least one bearing face of each prismatic module has an apparent external surface which results from the cutting surface of the foamed elastomer.

According to a first advantageous embodiment, all the faeces of all the prismatic modules can correspond to cutting planes of the foamed elastomer, the prismatic modules being manufactured in one piece by cutting from this foamed elastomer.

According to another embodiment, the angles of inclination of which are more pronounced than in the first embodiment, one of the support feces may correspond to a cutting plane of the foamed elastomer, and the adjacent support face may be fitted with anchoring devices attached to the foamed elastomer, for example provided with an adhesive layer, to limit the sliding of the latter face relative to the bare cutting faces.

A device according to a first embodiment of the invention may comprise a group of at least two prismatic modules, said at least two modules having the same angle of inclination between 5 ° and 15 °. More advantageously, this same angle of inclination can be between 7 ° and 13 °, preferably between 9 ° and 11 °. This first embodiment is particularly suitable for making stacks suitable for supporting a lower limb of a user.

In this embodiment, the device can include at least two modules, including:

-the base support faeces are rectangular in length between 23 cm and 33 cm, preferably between 25 cm and 31 cm, advantageously between 27 cm and 29 cm, and in width between 7 cm and 17 cm, preferably between 9 cm and 15 cm, advantageously between 11 cm and 13 cm.

-The thickness at rest of the module is between 2 cm and 8 cm, preferably between 3 cm and 7 cm, advantageously between 4 cm and 6 cm,

According to a preferred embodiment, the first edge of each module is sufficiently thin for its height at rest to be less than or equal to 0.8 mm, preferably less than or equal to 0.7 mm, advantageously less than or equal to 0.6 mm.

Measurements of these finest corners of the modules can be obtained in macro photography, the angle of which was compared to a millimeter measurement.

The height at rest can for example be measured when the module is placed on a horizontal plane by its base bearing face, by extending the plane of its inclined bearing face by a geometric plane, by projecting vertically on this plane the material limit of the module at its first edge, and by measuring the smallest distance from the horizontal plane of the projected line thus obtained.

This fineness of the first edge allows continuity of the support area of the user's body, which can be distributed between a contact area with the stacking of modules and a contact area with a more rigid floor, without pain. linked to a break in contact between the two support zones.

Advantageously, the angle of inclination of the modules and the number of modules of the device are designed to make it possible to create a series of at least two stacks, of which, to be adapted to the support posture chosen for the user, at each times the overall angle obtained with respect to the ground is between 5 ° and 40 °, preferably between 7 ° and 36 °, advantageously between 9 ° and 31 °.

The device can advantageously include a maximum of 6 modules, the total weight of the modules being between 500 g and 900 g, preferably between 550 g and 800 g, advantageously between 600 g and 700 g, and the total volume of the modules being between 3.6 dm ³ and 6 dm ³ , preferably between 4 dm ³ and 5.5 dm ³ , advantageously between 4.4 dm ³ and 5.2 dm ³ . This makes sure to have a compact device, light to transport, the density of the module material being nevertheless sufficient to ensure the elastic return necessary for the desired support function.

According to a second embodiment, a device according to the invention may comprise a group of at least two prismatic modules, said at least two modules having the same angle of inclination (63) of between 14 ° and 26 °, preferably between 16 ° and 24 °, advantageously between 18 ° and 22 °. This second embodiment is particularly suitable for making stacks suitable for supporting an infant's head.

Such a device can include at least two modules, including:

the base bearing faces are rectangular or substantially square, the side of the square or the widest of each rectangle being between 7 cm and 16 cm, preferably between 9 cm and 14 cm, advantageously between 10 cm and 13 cm.

-The thickness at rest of the module is between 2 cm and 8 cm, preferably between 1.5 cm and 6.5 cm, preferably between 2 cm and 6 cm, advantageously between 3 cm and 5 cm

Particularly advantageously, the thickness of the modules at the level of the first edge is less than or equal to 0.8 mm, preferably less than or equal to 0.7 mm, advantageously less than or equal to 0.6 mm. It thus leaves no thick relief capable of creating painful support zones for the user.

The overall angle formed by a set of superimposed modules, adapted to the chosen posture can advantageously be between 10 ° and 90 °, in particular 15 ° to 87 °, preferably between 19 ° and 81 °.

The total weight of the device according to this second embodiment is advantageously between 200 g and 240 g, in particular between 210 g and 230 g, preferably between 215 g and 225 g.

The total volume of this device is advantageously between 1 dm ³ and 3 dm ³ , in particular between 1.4 dm ³ and 2.5 dm ³ , preferably between 1.7 dm ³ and 2.2 dm ³ .

In the second embodiment, at least one module is fitted on its base support face, with an attached adhesive layer (65). Several, if not all, modules can be fitted in this way. According to a particularly advantageous embodiment, the self-adhesive adhesive layer can be obtained by depositing on the foamed elastomer, a mesh-forming net, itself coated with adhesive on both sides and protected by a sheet of paper or a protective film. peelable. The quantity of adhesive and the adhesive properties are chosen so that two modules can be assembled and then disassembled at least six times at the level of this adhesive face pressed against a non-adhesive face. The device can thus be used as an infant head support, its geometry being reconfigurable at least six times during the growth of the infant.

Preferably, the adhesive layer covers the entire base bearing face, or forms a network extending from one edge to the other of the base bearing face, for two first opposite edges as well as for the two other opposite edges.

The device according to the second embodiment may further comprise a support sole made of the same foamed elastomeric material as the modules, forming a rectangular mat of constant thickness, between 0.3 cm and 2 cm, preferably between 0.5 cm and 1.5 cm, advantageously between 0.7 cm and 5 1.2 cm, one side of the rectangular mat being at least as long as the first edge of the triangular prismatic modules, and the other side of the mat rectangular being strictly longer than twice the length of a second side of the base bearing face, said second side being perpendicular to the first edge.

The dimensions of the sole can thus correspond to a length between 10 27 cm and 39 cm, in particular between 29 cm and 37 cm, preferably between 31 cm and 35 cm and a width between 10 cm and 20 cm, in particular between 12 cm and 18 cm, preferably between 14 cm and 16 cm.

The upper face of the support sole is intended to receive the self-adhesive base of the prismatic modules which are to be peeled off and re-glued to adjust the settings at least 6 times.

The underside of the support sole can advantageously receive over its entire surface, a self-adhesive adhesive sheet, preferably in permanent screened adhesive adhering by its two faces, the outside of which is protected by a removable sheet of paper. This allows the entire device to be fixed on a support such as a mattress or backsplash of 20 Baby Relax armchairs.

Another fixation is possible for the sole is illustrated in FIGS. 20 and 21: it consists in making two slots at the ends of the sole b and in introducing therein a Velcro or loop type band passing through the sole, and making it possible to adjust the device around a mattress or back of a chair, this operation can be repeated many times.

The invention also relates to a method for manufacturing prismatic modules to form a device as described above, in which:

- we supply a closed cell foam block of elastomer

- at least one prismatic bar with a rectangular base 30 is cut from the elastomer block

-the rectangular prismatic bar is cut into two prismatic blocks with a triangular base, by attacking with a cutting beam or with a cutting tool, one face of the rectangular prismatic bar according to a depth of cut parallel to the directions of four edges of the bar ,

-the two prismatic modules thus cut are separated, at an edge of the module distinct from its first edge.

The method can also comprise a step in which the skin is removed from the molding surface of a block of foamed elastomer, so as to obtain a new block of truly homogeneous material. The fact of eliminating the surface skin of the block 40 makes it possible to avoid the presence of harder zones on or in the prismatic modules, which would go against the comfort of use of the device, or even create support points. painful preventing the use of the module.

Cutting by attacking a prismatic bar from the front by one side, makes it possible to limit the tearing of material that one would have, for example, by attacking a prismatic bar by an edge.

This process makes it possible to obtain two identical triangular prismatic modules and above all, while respecting the slope angle, to obtain a corner thickness less than 0.5 mm, between 0.2 mm and 0.8 mm, in particular between 0.3 mm and 0.7 mm, preferably between 0.4 mm and 0.6 mm.

According to a preferred embodiment, the cutting of the first prismatic bar can be provided to allow cutting of more than two prismatic modules, which then makes it possible to alternate a cutting along a bearing face and a cutting along the height of the modules and facilitates the maintenance of the prismatic bar by its remaining uncut portion.

In the illustrated embodiment, the module is made in one piece, without adhesive, or attachment system attached to the surface. The elastic dimensions and properties of the module are suitable for applications supporting a human foot.

Said prismatic module is, in the absence of mechanical stress, delimited by 40 in particular: a first support face 1 base and a second inclined support face

2, of substantially equal surfaces (ie differing by less than 10% in relative value), said bearing faces being rectangular or square, the base bearing face and the inclined bearing face meeting at a first edge 7 of the prismatic module, forming between them an angle of inclination 4.

The width 1 of the module is between 7 and 17 cm, preferably between 9 and 15 cm, preferably between 11 and 13 cm. A vertical rectangular lateral surface 3 perpendicular to the base, of height h between 2 and 8 cm, preferably between 3 and 7 cm, preferably between 4 and 6 cm and of width identical to that of the base but of length 8 ( hypotenuse) therefore slightly larger. The longitudinal section (hatched area) of module 5 shows a section S in a right triangle 90 ° whose angle a 4 is between 5 ° and 15 °, preferably between 7 ° and 13 °, preferably between 9 ° and 11 °. The cutting thickness of this angle 4, the thinnest varies between 0.2 and 0.8 mm, preferably between 0.3 and 0.7 mm, preferably between 0.4 and 0.6 mm. The angle a 5 is complementary to the angle a 4, the sum of which represents 90 °. No corner is truncated. The assembly of several of these modules allows the creation of passive support posture devices adapted to orthopedic and circulatory problems of the lower limb.

FIG. 2 represents the perspective of a single-piece right triangular prismatic module, according to a second embodiment of the invention with permanent screened adhesive 65 applied to the base, the measurements of which are defined by the dimensions of the head of the newborns and His development. A device comprising an assembly of such modules is intended to support a newborn skull.

This wedge-shaped module corresponding to the second embodiment, comprises: a base surface 60, square, of length L between 7 and 16 cm, preferably between 9 and 14 cm, preferably between 10 and 13 cm, of identical width 1. A surface 62 perpendicular to the base, of height h between 1.5 and 6.5 cm, preferably between 2 and 6 cm, preferably between 3 and 5 cm and of width identical to that of the base. An inclined surface 61, of width identical to that of the base but of length 66 (hypotenuse) therefore of slightly larger surface. The longitudinal section S shows a right triangle section at 90 ° whose angle a 63 is between 14 ° and 26 °, preferably between 16 ° and 24 °, preferably between 18 ° and 22 °. The thickness of the cut at this angle a 63, the thinnest, varies between 0.2 and 0.8 mm, preferably between 0.3 and 0.7 mm, preferably between 0.4 and 0.6 mm. The angle a 64 is complementary to the angle 63, the sum of which represents 90 °. No angle is preferably truncated or changed. The assembly of several of these modules of the second embodiment allows the creation of passive support posture devices adapted to the problems of skull deformation in newborns.

FIG. 2 also shows the perspective of a rectangular sole b, located under the triangular prismatic module a, which adheres to the sole b, the sole b serving to support the module a, or to several modules a (the additional modules do not are not shown in Figure 2). This sole b is characterized by a length L of between 27 and 39 cm, preferably between 29 and 37 cm, preferably between 31 and 35 cm. Its width 1 is between 10 and 20 cm, preferably between 12 and 18 cm, preferably between 14 and 16 cm. Its thickness 69 is between 0.3 and 2 cm, preferably between 0.5 and 1.5 cm, preferably between 0.7 and 1.2 cm. The sole is provided on a whole surface 68 with a permanent screened adhesive 67, covered with a protective sheet.

Regarding the adhesives 65 of the modules intended for postures of the head of newborns, or those 67 applied to the surface of the support sole, several fixing means are envisaged. The one described is 65-67 permanent screened adhesive. It is represented by a synthetic mesh coated with glue on both sides and covered with a paper or film protector. Its advantage is to prevent the material to which it is applied from expanding. It can be peeled off and re-bonded at least six times without damaging it. The goal is to be able to adjust the spacing of the blocks of posture modules A and B - as illustrated in Figures 22-23-24-25-26, as the infant's head develops, and ensure infant a progressive and precise reduction of cranial deformation.

Characteristics of the adhesive in an advantageous embodiment for the device: Adhesive weight between 50 and 100 g / m ² , preferably between 60 and 90 g / m ² , preferably between 70 and 90 g / m ² . Protective weight between 55 and 105 g / m ² , preferably between 65 and 95 g / m ² , preferably between 65 and 85 g / m ² .

Peel strength of the protector between 0.65 and 0.90 N / 5 cm, preferably between 0.70 and 0.90 N / cm, preferably between 0.75 and 0.85 N / cm FINAT standard 3. Peel value on polypropylene after 24 hours between 12 and 16 N / 2.5 cm, preferably between 13 and 15 N / 2.5 cm, preferably between 13.5 and 14.5 N / 2.5 cm standard AFERA 5001. Tackiness or TACK at the loop between 8 and 12 N / 2.5 cm, preferably between 8.5 and 11.5 N / 2.5 cm, preferably between 9 and 11 N / 2.5 cm FINAT standard 9.

Theoretical temperature of use authorized for the adhesive going from -30 ° C to + 110 ° C for example. Can also be used a double-sided adhesive, associated with a paper protector which is a polyester film coated with glue on both sides. It is applied to the base 65 of modules intended for the postures of the head of newborns and those applied to the surface of the support sole (68). It is easier to take off but less resistant to breakage. It is reusable less often, about 4 times.

Regarding the fixing of sole b (Figure 2) on a mattress or against the back of a so-called Relax chair, the Velcro or buckle type strap is to be preferred. It securely fixes the device and prevents it from moving. It is constantly reusable so as not to hinder the fixing of the two stacks of modules A and B. On the assembly of the

Figure 20, the strap S (illustrated in Figure 21) must run through the underside of the sole b, come out through the slots at both ends, cover the adjacent outer edges and be folded under the mattress or behind the backsplash until it is securely connected.

The fineness of the angles 4 and 63 Figures 31-32, forming the first edge of each module, is less than 1 mm and such angles with a fine edge can be obtained as follows: one cuts in the overall mass of a block of elastomer, rectangular prismatic bars with the dimensions appropriate to the required modules, then these rectangular prismatic bars are placed on their profile and finally, before detaching them from the bar, these rectangular prisms are sliced at an angle in order to obtain two identical triangular prisms. This cutting mode is illustrated in Figures 28-29. The goal is not to create any edge whose thickness of the chamfer would be able to deeply mark, or to hurt, during a prolonged posture, the integuments of the user. This process is all the more appropriate when it is addressed to the postures of the head of infants which is very sensitive and malleable. The superimposition of prismatic modules must exert a fade with the sole which serves as support and which supports the head of the new born. This fade can be improved by shifting the first edges of the upper module (s) relative to the first edges of the underlying modules so that a single corner edge at 63 comes into contact with the sole. This leaves a relief of less than 0.5 mm since it is itself flattened by the weight of the head or lower limb.

The choice of the unique elastomeric material used for the realization of the passive stretching posture devices meets precise requirements of firmness and flexibility at the same time, as much to absorb and support a load going up to 120 kg as that not exceeding 1 at 4 kg exerted on a sole whose thickness meets these requirements. The material may be an EPDM (ethylene-propylene-dienomonomer) cellular rubber molded with closed cells. Such an elastomer offers the user high resilience and low remanence (rapid resumption of its initial shape after deformation) very satisfactory. When it comes to hygiene, closed cells protect against moisture and dirt. The use of this material gives the passive stretching posture devices of which they are composed, great efficiency in exceptional comfort.

Example of suitable technical characteristics, alone or in combination between ownership groups for the modules of the devices according to the invention:

As illustrated in FIG. 3, a device for supporting postures of the foot can comprise 4 modules with 6 identical prismatic modules (only 4 modules are shown in FIG. 3), in the assembly illustrated, four prismatic modules are used. The superposition of the modules 10-11-12 forms an anterior block A intended to receive the sole of the foot whose maximum posture angle responds to the total flexion of the ankle of approximately 27 ° C. The block B comprises a rear module 13 in the form of a wedge which slides under the module 10 of the block A and receives the heel of the user. It acts as a shock absorber and stopper and prevents it from rolling back. Indeed, the pressure exerted on the heel by the weight of the body on point 14 combined with the crushing and the roughness of the material prohibits the separation of the blocks A and B. The first edges 7 of each module are all superimposed on along line 14. By block which slides relative to another or sliding from one block relative to another, it is understood throughout the text that the relative position of the blocks can be adjusted before use to adapt the stacking to user needs. When in use, once in chaige, the blocks no longer slide against each other.

The specific assembly of identical non-adhesive modules, in the form of overlapping corners, is intended to receive the passive vertical load from the user. In the embodiment of FIG. 8, the user engages the heel in the stop 13 and the sole of the foot on the upper slope 12 created by the superposition of the three modules 1015

11-12 of block A. Its position is vertical, the knee is stretched. The posture is passive and indicates that to avoid pitching the user should preferably stand against the wall, a door or window handle or other point of support.

Depending on the user's feeling, the angle of flexion posture can be reduced by removing one or two modules from block A, or increased by adding a fourth module superimposed on the previous three, well indicated for maximum stretching, in maintenance. , often contracted muscles of athletes.

The penetration of the module 13 under the module 10 superimposed at the level of the line 14 can vary from% to the length of the module 13 and allows, by sliding, to refine degree by degree, the posture angle by increasing or decreasing the slope according to the need for a precise adjustment of adaptation, at the limit of pain making the application more effective.

This mode of posture (figure 8) allows the stretching of the posterior fascia of the leg, from the sole of the foot to the pelvis. It is an anti-equinism device, it restores flexion of the ankle, reduces pressure on the joints and prevents early osteoarthritis.

Figure 9 similar to Figure 8 shows the implications of the posture obtained by superimposing the modules with the release of venous circulation back on the saphenous vein, the most common place for varicose veins.

In the embodiment of FIG. 10, block A, posterior, comprises three prismatic modules 10-11-12 superimposed and receives on its upper face the heel and the sole of the foot up to the heads of the metatarsals. The angle thus established allows the ankle, the extension of the foot on the leg.

An additional module superimposed on the previous three accentuates the posture angle and can respond to the maximum ankle extension of around 40 °. The anterior block B includes a wedge-shaped module 13 and receives all of the toes on its inclined upper face, lifting them up. The module 13 penetrates from% to Ά of its length under the module 10 to the end point of junction 14. It allows precise adjustment of an angulation at the limit of pain.

The vertical pressure exerted by the weight of the user on the forefoot and toes depresses and blocks the underlying modules which, combined with the roughness of the material, prevents any slipping and keeps the whole in cohesion. This extended posture device stretches the muscles of the anterior compartment of the leg as well as those of the sole of the foot, and in particular those responsible for the hammer toes.

Figure 11 similar to Figure 10 shows the same posture where the superposition of an additional module 15 in the form of a corner, inverted under the module 13 very strongly accentuates the stretching in extension of the hammer toes when the upper edge of the vertical plane 3 figure 1 interferes in the concavity of the toes and pushes them back into straightening.

We can further increase the extension posture angle by adding an additional module superimposed on the upper face 12 of block A.

Figure 4 shows a method of use showing three prismatic modules. A longitudinal module 22 on which the user's foot rests, the heel T on the thinnest part and the front of the GO foot (for big toe and PO for small toe) on the thickest part. Two side modules 20 and 21, superimposed, the finest corners of which are engaged perpendicularly under the front and external part of the longitudinal module 22 making it possible to lift the external edge of the forefoot. This passive posture of the foot is used for the reduction of the deformed foot in varus. The sliding of the modules 20 and 21 under the module 22 makes it possible to refine the posture angle of the forefoot.

FIG. 5 represents the assembly of three modules belonging to a device according to the invention, showing 3 prismatic modules: - Two longitudinal modules 23 and 24, superimposed, on which the foot rests. The T heel on the thinnest part of the modules and the Go and Po forefoot on the thickest part. This allows, by passive stretching posture, to reduce the retraction of the calf and release the tension it exerts on the heel thus facilitating the correction of this deformation; - A lateral module 25, the finest corner of which is engaged perpendicularly under the posterior and internal part of the module 23 exerts a lateral tilting of the heel by lifting its internal edge such that the top rocks outwards and the sole of the heel is raised and look inward.This posture of the foot is used to reduce the talus varus. Sliding the module 25 under the module 23 makes it possible to refine the heel posture angle.

FIG. 6 represents a method of using a stack of 4 prismatic modules of a device according to the invention: - A longitudinal module 28 in the form of a corner on which the foot rests. The heel T on the thinnest part of the module and the Go and Po forefoot on the thickest part; - Two superimposed lateral modules 26 and 27, the finest corners of which are engaged perpendicularly under the front and external part of the module 28, lifting it up; - A lateral module 29, the finest corner of which is engaged perpendicularly under the rear and internal part of the module 28 and lifts it up. The sliding of the front lateral modules 26 and 27 and rear 29, under the module 28, makes it possible to refine the angle of twist of the foot and to make more tolerable the passive posture undergone by the user. This device contributes to the reduction of a twist inside, of the foot.

Figure 7 shows a method of using a group of three prismatic modules. The longitudinal module 32 receives the vertical load exerted by the weight of the user according to the arrangements described T for the heel on the thinner part of the module 32 and the forefoot Po and Go on the thicker stretching part d the calf. The two lateral modules 30 and 31, juxtaposed, perpendicularly engage the thinnest corner along the entire length of the external edge of the module 32 and lifts it up (Two additional modules can be superimposed on the modules 30 and 31 thus increasing the posture angle) .

The sliding of the side modules 30 and 31 under the module 32 makes it possible to refine the internal rotation angle of the foot. This device contributes to the reduction of the internal rotation of the foot or supination.

Figure 12 shows a method of use showing 3 prismatic modules. The module 34 receives the heel T on its inclined face and serves as a stop. Its finest corner is applied perpendicular to point A of module 35, and 36 superimposed at their thinnest parts. On the upper face of the module 36 rest in the established order the small toe upstream and the big toe downstream. The right foot is placed at an angle of 30 ° to 60 ° depending on the angle sought, to obtain an increasingly powerful lowering of the inner arch of the foot by lifting its outer edge. In this same posture, the calf is stretched. This method stretches the arch muscles by decreasing its tendency to increase. The sliding of the perpendicular module 34 under the module 35 makes it possible to refine the posture angle of the foot and makes it more precise and bearable.

FIG. 13 represents an arrangement substantially symmetrical to that of FIG. 12, where the thinnest corner of the module 39 is applied perpendicular to the point A of the modules 37, and 38 superimposed at their thinnest parts. On the upper side of module 38, rest in the established order the big toe Go upstream and the little toe Po downstream. The right foot is placed at an angle of 30 ° to 60 ° depending on the angle sought to obtain an increasingly strong elevation of the internal arch of the foot by lifting its internal edge. In this same posture, the calf is stretched. This method increases the arch of the foot. The sliding of the perpendicular lateral module 39 under the module 37 makes it possible to refine the posture angle of the foot and makes it more precise and bearable.

Note that Figures 4-5-6-7-12-13 illustrate assemblies intended for stretching at the level of a user's right foot.

Figures 14 and 15 show a stack in use configuration showing four prismatic modules distributed in two blocks of two superimposed modules 40-42 and 41-43, opposite longitudinally and joined by their thickest edge. Block B receives the heel at its highest part, block A receives the forefoot at its highest part. The blocks B and A joined together, exert at their highest points on the plantar muscles, a pressure represented by the weight of the body, which makes it possible to stretch them and to strengthen the collapsed bones of the foot. This method can be used to polish the reduction of diminished arch.

Figures 16 and 17 show an assembly with four prismatic modules distributed in two blocks of two superimposed modules 44-46 and 45-47, face to face, longitudinally opposite by the edges of the thinnest corners. The block B receives the heel on the middle part of the upper face of the module 46. The block A receives the head of the metatarsals and the toes on the middle part of the upper face of the module 47. The arch thus left in the void, by the vertical load exerted by the body weight tends to lower, stretching the underlying muscles. This method can be used for the reduction of the raised arch towards the hollow feet.

Figures 18 and 19 show another mode of use showing four prismatic modules arranged differently. The single module B 48 receives the heel at its middle part and serves as a stop. The module A comprises three superimposed modules, the module 49 is arranged in the same way as the model 48. The module 50 is superimposed and inverted in order to obtain a rectangular prism on which the module 52 is added. It receives the front -foot, respects its slope and makes the posture more comfortable Figure 19. Figure 18 shows the module 51 inverted compared to the module 52 in order to increase the height of the passive stretching posture by two heights of modules superimposed by their edge the upper. This method allows for major stretching of the retracted arch muscles and can be used against increased arch.

FIG. 20 illustrates, in configuration of use, another device according to the invention, certain elements of which (prismatic modules a, sole b) are already described in FIG. 2. FIG. 20 represents a global device for passive posture to aid in the reduction of deformations of the head of the newborn and congenital torticollis. It shows a sole b, adhesive 67, on one of its faces or fixed by strap S (illustrated in Figure 21 showing a section C-C 'in Figure 20), on which rest two blocks A and B each formed by several modules bunk.

Each of the modules from 70 to 78 and from 80 to 85, all identical, adheres 65 over its entire surface to the underlying module by its base, by a double-sided adhesive or a permanent screened adhesive. The devices for osteo-articular postures and muscle stretching, applied early from an early age to the congenital torticollis Figures 22 and 23, and to head deformities such as plagiocephaly (Figures 22 and 23), or brachycephaly (Figures 24 -25-26), prevent during the development of the infant, the appearance of possible scoliosis or other vertebral deformities, early osteoarthritis to which are added functional and aesthetic deficits.

The embodiments illustrated in FIGS. 22 to 27 schematically illustrate the contact zones between the skull of a newborn and a support device according to the invention, depending on the position of the skull and the geometry of the skull at the time of support. We see that the pressure zones tend to regularize the shape of the skull.

The angle of the first edge (referenced 63 in FIG. 2) is identical for each module of a given device (device according to the first embodiment, for supporting the lower limbs, or device according to the second embodiment , to support the head of a newborn). The height of its edge, preferably less than 0.5 mm, allows it to withstand prolonged postures without marking or damaging the integuments at the level of the user's support feces by default in relief.

Figures 28, 29 and 30 show cutting diagrams of a manufacturing method according to the invention, method, which allows in the same geometry of a cellular rubber bar, to achieve all the devices described above.

FIG. 28 illustrates a method of cutting modules adapted to orthopedic problems of the lower limb: the rectangular prismatic bar is placed on its narrower side and oriented according to the desired corner angle, then it is cut vertically right through the diagonal. We then obtain two identical triangular prisms. Six modules are sufficient to compose a prismatic module assembly device, ankle and foot corrector.

FIG. 29 illustrates a method for cutting modules adapted to orthopedic problems of the head of newborns: in the same bar, a sheet is sliced horizontally which makes it possible to create the sole on which the blocks A and B rest (illustrated in FIGS. 2 , 20, 22, 23, 24, 25, 26). Then the remaining part of the rectangular prismatic bar described above is placed in the same way and cut vertically along the diagonal. We then obtain two identical triangular prisms. Six modules plus a sole are sufficient to compose a device to correct deformations of the head of the newborn.

Figure 30 shows that in the same bar, one can realize the two devices of the first embodiment and the second embodiment described above.

The invention is not limited to the embodiments described, and can be declined in numerous variants: the device can thus comprise less than six modules, or can comprise at least one module having an angle of inclination substantially different from the tilt angle of the other modules. The prismatic shape of the modules can be obtained by other methods than cutting from the mass, for example by cutting an extruded profile of elastomeric foam, or even by individual molding of each module.

The number of superimposed modules and the spacing of the blocks A and B allow for precise adjustment to vary the posture angles and to adapt them to the user.

The elastic (or viscoelastic) force feedback properties of the material give module assemblies great efficiency in exceptional comfort.

The assembly of simple and identical modules makes it possible to configure the device for a wide variety of static postures recommended in response to the numerous pathological deformations which justify them.

The uniqueness of geometry, the size, the weight and the limited size of the module and the device to which it belongs facilitate the handling, the speed of assembly and the storage of this product. Its simplicity, its stereotype facilitates manufacturing and makes its cost very attractive.

The material is well tolerated by the body. For hygiene, it is recommended to insert a cotton cloth between the user's head and the device.

The invention also relates to an installation procedure for the use of prismatic modules for one or more of the following applications: Reduction of joint limitations and deformations of the bones, ankle and foot. Reduction of muscular, aponeurotic and facial contractures and retractions of the lower limb, from the foot to the pelvis and beyond, by passive vertical support postures, using body weight, and their consequences on circulatory venous return.

The invention relates in particular to an installation procedure for the use of prismatic modules for the flexion posture, stretching of the ankle, the calf Figure 8 and the prevention of heavy legs and varicose veins Figure 9, characterized in that a group of module A present at the forefoot, a height greater than that of module B, of the heel, located in the extension and underlying the block A.

Another installation procedure for the use of prismatic modules is characterized in FIG. 12, in that the module 34 is juxtaposed, side A, perpendicular to the modules 35 and 36, or more, superimposed. This increases the power of the anti-varus posture in the outward orientation, from 30 ° to 60 ° of the foot.

The invention also relates to an installation procedure for the use of prismatic modules for the posture of lifting the internal edge of the forefoot, known as anti-valgus: It is the reverse process of the previous one, characterized in that the longitudinal module 22 is raised to its front and internal half by one or more superimposed modules 20-21, engaged perpendicularly, more or less, under the front and internal half of module 22.

Another installation procedure for using prismatic modules is characterized in FIG. 13, in that the module 39 is juxtaposed, side A, perpendicular to the modules 37 and 38, or more, superimposed. This increases the power of the anti-valgus posture according to the inward orientation, from 30 ° to 60 °, of the foot.

Another positioning procedure for the use of prismatic modules for the posture of lifting the internal edge of the heel known as anti-talus valgus is characterized in FIG. 5 in that one or more superimposed longitudinal modules, 23-24 are raised under their half posterior and internal by module 25 or more, superimposed, engaged perpendicularly under module 23.

An installation procedure is also proposed for the use of prismatic modules for the posture of lifting the external edge of the heel, said anti-talus varus: this is the reverse process of the previous one, characterized in that one or more longitudinal modules superimposed, 23-24 are raised under their posterior and external half by the module 25 or several superimposed, engaged perpendicularly under the module 23.

The invention also relates (FIG. 6) to an installation procedure for the use of prismatic modules in order to practice a reduction of the torsion of the foot inside by a posture combining a lifting of half of the external anterior edge of the foot ( as in Figure 4); and a lifting of the internal edge of the heel (as in FIG. 5), characterized by a longitudinal module 28, the thickest part of which faces forward, the antero-external half of the module 28 being raised by the superposition of two modules 26-27 or more, engaged perpendicularly under the module 28. The module 29 is engaged perpendicularly under the posterior and internal half of the thin part of the module 28, lifting it slightly.

An installation procedure is also proposed for the use of a wedge-shaped module for the posture of lifting the half of the anterior and internal edge of the foot associated with the posture of lifting the external edge of the heel, known as reduction of the torsion of the foot. outside, which combines the reduction of the valgus foot with that of the talus varus of the heel, known as reduction of the torsion of the foot outside. It is the reverse process of the previous one, characterized by: a longitudinal module 28, the thickest part of which faces forward. The antero-internal half of the module 28 is raised by the superposition of two modules 26-27 or more engaged perpendicularly under the module 28. The module 29 is engaged perpendicularly under the posterior and external half of the thin part of the module 28, lifting it slightly.

The invention also relates to a fitting procedure for using prismatic modules for the posture of lifting the external edge of the foot over its entire length called reduction of the internal rotation of the foot or supination, characterized (Figure 7) by: a module longitudinal 32, the thickest part of which faces forward. The juxtaposed modules 30-31, or groups of superimposed modules, penetrate perpendicularly under the entire length of the external edge of the module 32 and lifts it.

In addition, an installation procedure is proposed for the use of prismatic modules for the posture of lifting the internal edge of the foot over its entire length called reduction of the external rotation of the foot or pronation, this is the reverse process of the previous one. Characterized by: a longitudinal module 32, the thickest part of which faces forward. The juxtaposed modules 30-31, or groups of superimposed modules, penetrate perpendicularly over the entire length of the internal edge of the module 32 and lifts it.

The invention also covers an installation procedure for the use of prismatic modules according to different applications, for the reduction of flat foot by elevation of the arch of the foot, characterized in Figure 14 and Figure 15 in that two blocks A and B, of one or two superimposed modules 40-42 and 41-43, longitudinally opposite, are joined by their thickest edge, thus defining a highlight whose angle varies according to the number of superimposed modules.

Finally, and in a nonlimiting manner, the invention proposes an installation procedure for the use of prismatic modules according to different applications for the reduction of the hollow foot by lowering the arch of the foot, characterized in Figure 16-17 and Figure 18 and 19 in that two blocks A and B, of one or two superimposed modules 1617, opposite longitudinally, are joined by their thinnest edge, thus defining an angle open upwards, therefore the amplitude depends on the number of superimposed modules.

Another, more powerful arrangement, aimed at reducing the arch of the hollow foot, by prismatic modules, is characterized in Figure 19 in that blocks B and A are arranged in such a way that the module 48 of block B is located behind block A, the thinnest point facing forward. The block A located in front of the block B, brings together the superposition of the module 49 and the inverted module 50 forming a rectangular prism on which the module 52 is superimposed, accentuating the slope towards the front and the top of the block A corresponding to the forefoot.

Another, even more powerful arrangement, aimed at reducing the arch of the hollow foot, of prismatic modules, is characterized in Figure 18 in that two blocks B and A are arranged in such a way that the module 48 of block B is located in back of block A, the thinnest point facing forward.

Block A located in front of block B combines the superimposition of modules 49 and inverted module 50 forming a rectangular prism on which is superimposed the inverted module 51, increasing the height of the rear wall of block A including the stretching constraint of l forefoot on the heel, therefore from the arch to the lowering.

The invention also covers a support device for passive osteoarticular postures and muscle stretching, for reducing congenital torticollis and plagiocephaly (illustrated in Figures 2,20, 21, 22, 23) characterized in that it comprises:

1 °) A set A in the block of one or more removable modules superimposed 70-7172 mums at their bases with a permanent screened adhesive 65.

2 °) A set B or block of several superimposed removable modules 75-76-7778 whose maximum overall angle does not exceed 90 °, provided at their bases with a permanent screened adhesive 65.

It receives, members on it, the two blocks A and B, adjustable in spacing. The whole forms a device according to the invention.

The invention further relates to a support device for passive osteoarticular postures and muscular stretching, reduction of brachycephaly, Figure 2, 20, 21, 24, 25, 26) characterized in that it comprises:

1 °) A set A or block of one or more superimposed removable modules 8081-82, provided at their bases with a permanent screened adhesive 65.

The device is identical to the previous one for plagiocephaly except that the posture must be alternately reversed daily Figure 24 and 25.

Another arrangement, aimed at reducing brachycephaly by prismatic modules and characterized in FIG. 26 in that the blocks A and B of superposed adhesive modules, namely 80-81-82 and 83-84-85 are perfectly identical in shape and in number, whose spacing allows a balanced corrective posture C-C 'provided that it leaves an underlying corrective vacuum. The blocks A and B adhere the rectangular support sole b Figure 2 - b Figure 20-26 fitted with a permanent screened adhesive 67 or a Velcro or loop type tape Figure 21 for fixing.

The invention further relates to a method for manufacturing prismatic modules illustrated in FIGS. 28, 29, 30, characterized in that the polyurethane bar, detached from the primitive block is placed perpendicularly on its narrower side then at an angle to the desired angle and then cut perpendicularly, which makes it possible to obtain a constant angle of 4 or 63 (Figures 31, 32) whose thinnest cutting thickness varies between 0.2 and 0.8 mm, at least between 0.3 and 0.7 mm, preferably between 0.4 and 0.6 mm. The same bar Figure 28, (Figure 1 and Figures 3 to 19), after having preliminary cut (Figure 29) a rectangular sole, will be cut at a very slightly different angle (Figure 2 and Figures 20 to 27), following the procedure below. above cited in order to obtain the same fineness of cuts as above described, varying between 0.2 and 0.8 mm, at least between 0.3 and 0.7 mm, preferably between 0.4 and 0.6 mm thus avoiding by the superposition, to create a relief likely to mark or injure the user. Bars to which a sheet of 65-67 permanent screened adhesive is fitted. This procedure allows the uniqueness of the two types of modules and above all an ease of production, the scope of which is to manufacture a large number of modular parts for precise and economical assemblies.

The use of a group of identical prismatic modules makes it possible to produce a wide variety of devices, limited to 6 modules per set, suitable for 12 applications relating to FIGS. 1 and 3 to 19 as well as to 3 applications relating to FIGS.

27. This configuration also makes it possible to keep constant the size, the weight, the bulk of the device and by the simplicity of its design, to facilitate handling, speed of assembly, transport and storage.

The modules and assembly of EPDM cellular rubber modules, intended to support the lower limb Figure 1 and of Figure 3 to 19, can dispense with the addition of adhesive surfaces. The material cells are closed inside the initial monolith block but open on its cutting edge. The roughness of these cut cells, the low angle of inclination and the consequent vertical load of approximately 50kg to 100 kg, increase the cohesion between the modules and develop their adhesion between them and their adhesion to the ground. In this device, we can therefore dispense with inserting a non-slip base mat and placing a self-adhesive sheet under each module.

The present invention provides a simple device of multifunctional triangular prismatic monoblock modules, preferably all identical, which can, used assembled or in some cases used individually, serve as support during static postures for prevention and therapy, by passive postures support of deformations of the foot, ankle and head. To date, users rate the device as being absolutely comfortable and practitioners consider it to be remarkably effective.

The devices according to the invention are light, stable and unbreakable.

Their firmness and flexibility confer exceptional comfort and the ability to provide over long hours, the support adapted to a passive posture of correction without injuring the user.

Juxtaposed or superimposed, the modules allow an adaptation of the geometry of the device by spacing the modules from a first assembly position and thus allow, to refine and make more precise, the posture angle so that it is both efficient and bearable.

The modules allow immediate and continuous external visual control, permanently facilitating constant monitoring of the quality of the settings and their rapid adjustment according to changes and progress.

They offer the user absolute freedom of positioning outside the constraints of placing the support point.

The modular devices according to the invention are simple systems, less rigid, less brittle, than known systems, stable, light, adjustable comprising the same number of elements, all identical, compact, easy and quick to handle, which make it possible to numerous postural applications using passive support postures.
