Description

POSTUROLOGY DEVICE, PARTICULARLY SUITABLE FOR
POSTURAL CORRECTIONS
The present invention relates to a posturology device, particularly suitable for postural corrections.
Currently, the field of orthopedics offers a plurality of footbeds intended to perform several functions, from improving the comfort of the shoe in which they are used, to becoming an actual posturology device adapted to correct the posture of the user.
These footbeds of the known type are formed generally by two layers which are mutually associated and are intended respectively to make contact with the foot of the user and with the inner side of the sole of the shoe in which the footbed is applied.
In greater detail, footbeds are known which are made of various materials, for example leather, fabric, rubber or other material, are mutually joined by means of stitches and/or adhesive and on which there are portions that correspond to precise regions of the sole of the foot, so as to constitute a precise plantar mapping that provides a one-to-one match between a region of the foot and a region defined by the mapping on the footbed.
Each region of the foot in fact corresponds to a specific muscle chain that supports said region, as is known from medical textbooks.
In order to apply pressure on said regions of the foot, said portions of footbeds of the known type are made of materials that are harder than the rest of the footbed or are filled, for example with polyurethane chips (PPT), thus providing specific proprioceptive stimuli.
However, this solution of the known type does not provide valid help toward correct posture but stimulates only the muscle chains, alleviating any inflammations, and corrects muscle and joint pains that derive indeed from incorrect postures, without however preventing postural defects that are not diagnosed until they become a cause of discomfort.
Correct posture is in fact simply the most suitable position of our body in space to perform the antigravity functions with the smallest dynamic and static energy expenditure.
The aim of the present invention is to overcome the drawbacks cited above, by providing a posturology device that is capable of correcting incorrect postures and at the same time teaches the user to assume correct positions with a sort of postural gymnastics.
Within this aim, an object of the present invention is to provide a posturology device that thanks to its particular constructive characteristics is capable of giving the greatest assurances of reliability.
Another object of the invention is to provide a posturology device that uses easily commercially available materials and is therefore easy to provide and therefore economically competitive if compared with footbeds of the known type.
This aim, as well as these and other objects that will become better apparent hereinafter, are achieved by a posturology device, particularly suitable for postural corrections, comprising a footbed that is provided by at least two layers which are mutually associated and are adapted to define a plurality of mutually isolated closed interspaces, characterized in that it comprises rounded granules that can move freely within at least one of said closed interspaces so as to provide the central nervous system with a continuous variation of the perception of balance that is different so as to activate at each step muscle chains of the user that are responsible for postural adaptation thereof.
Further characteristics and advantages of the invention will become better apparent from the description of a preferred but not exclusive embodiment of a posturology device, particularly suitable for postural corrections, according to the invention, illustrated by way of non limiting example in the accompanying drawings, wherein:
Figure 1 is a perspective view of the posturology device according to the present invention; Figure 2 is an exploded perspective view of the posturology device according to the present invention;
Figure 3 is a sectional view of the device shown in Figure 1, taken along the sectional line III-III.
With reference to the figures, the posturology device, particularly suitable for posture corrections, generally designated by the reference numeral 1, comprises a footbed 2 that is provided by at least two layers 3 and 4, an upper one and a lower one, which are mutually associated and are adapted to define a plurality of interspaces 5, 6, 7 and 8 which are closed and mutually isolated.
More specifically, the upper layer 3 and the lower layer 4, which can be made of fabric, rubber, leather or other material and are respectively intended to make contact with the foot of the user and with the inner side of the sole of the shoe in which the footbed 2 is applied, are mutually associated by means of stitches 11 that delimit at the same time the closed interspaces 5, 6, 7 and 8.
In the proposed embodiment, there are four closed interspaces and in greater detail:
- a first closed interspace 5 that has a substantially triangular plan shape with rounded corners and is defined at a first end portion of the footbed 2 that is intended to make contact with the toes of the foot of the user,
- a second closed interspace 6 that has a substantially elliptical plan shape and is defined at a central portion of the footbed 2, proximate to the first end portion, and is intended to make contact with the transverse arch of the foot of the user,
- a third closed interspace 7 that has a substantially elliptical plan shape and is defined at a second end portion of the footbed 2, which is opposite the first end portion and is intended to make contact with the heel of the foot of the user, and
- a fourth closed interspace 8 that has a substantially trapezoidal plan shape and is defined at the central portion of the footbed 2 between the second closed interspace 6 and the third closed interspace 7.
According to the invention, rounded granules 9 are provided that can move freely within at least one of the closed interspaces 5, 6, 7 and 8 in such a manner as to provide the central nervous system with a continuous variation of the perception of balance that is different, so as to activate at each step muscle chains of the user that are responsible for his postural adaptation.
In greater detail, in the proposed embodiment the rounded granules 9 are accommodated in the first three closed interspaces 5, 6 and 7.
Such rounded granules 9 comprise substantially spheroidal bodies, for example made of glass with variable dimensions with a maximum diameter that is substantially equal to 1 mm or is in any case smaller than 3 mm.
Advantageously, the upper layer 3, intended to make contact with the foot of the user, is made of a material that has a thickness substantially of 0.6 mm and is characterized by elastic anisotropy so as to give the footbed 2 a longitudinal elasticity coefficient that is smaller than the transverse elasticity coefficient.
In this manner it is possible to contain the longitudinal elongations of the upper layer 3 under the weight of the user, so as to ensure a uniform distribution of the rounded granules 9 contained in the closed interspaces 5, 6 and 7.
As regards the lower layer 4, the latter is substantially 2 mm thick and is made of rubber with a smooth face and a corrugated face, so as to allow optimum sliding of the rounded granules 9 within the closed interspaces thanks to the smooth face that is directed inwardly, while the lower part in contact with the shoe, which is of the rough knurled type, creates higher friction and does not allow the sliding of the footbed 2.
Conveniently, the closed interspaces 5, 6 and 7 and 8 are provided on the footbed 2 according to precise lines that are known from specialist medical studies in podology, posturology and sports medicine so as to represent a precise mapping of the terminal system of the foot.
In this manner, wearing the posturology device 1 in normal shoes a situation that is similar to, and better than, walking barefoot is created, with an infinite amount of information to the terminal system of the foot, which can vary and is continuous, and is produced by the continuous and imperceptible movement of the spheroidal bodies having different dimensions.
The central nervous system reacts to these stimuli with a continuous motor response to adaptation, performing a sort of postural gymnastics.
Advantageously, there is an additional reinforcement layer 12 that is interposed between the two layers 3 and 4 at least at the first three closed interspaces 5, 6 and 7.
Such additional reinforcement layer 12 is associated with the upper layer 3 by adhesive bonding with water-based glues substantially along its entire extension, so to prevent the formation of creases of the materials of which the additional reinforcement layer 12 and the upper layer 3 are made.
In this manner, the rounded granules 9 are contained between the lower layer 4, intended to make contact with the inner sole of the shoe in which the orthopedic device 1 is inserted, and the additional reinforcement layer 12.
Furthermore, such additional reinforcement layer 12 is also made of a material that has an elastic anisotropy in order to give locally to the footbed 2 a longitudinal elasticity coefficient that is greater than the transverse elasticity coefficient.
More specifically, the additional reinforcement layer 12 and the upper layer 3 are mutually crossed with respect to their anisotropic directions, so as to give rise to a stronger structure, avoiding structural yielding in the longitudinal and transverse direction located at the closed interspaces 5, 6 and 7, reducing over time the negative effect of excessive elasticity. Furthermore, at least one reinforcement element 10 is provided that is accommodated in one of the closed interspaces 5, 6, 7 and 8 and, more specifically, in the fourth closed interspace 8.
The insertion of such reinforcement element 10, for example with a thickness comprised between 0.4 and 0.6 mm, provides a structural reinforcement that avoids the "crease" effect of the yielding of the upper layer 3 and at the same time allows optimum flexibility and adaptation to any possible shape of the shank of the shoe.
In practice it has been found that the posturology device particularly suitable for postural corrections, according to the invention, achieves fully the intended aim and objects, since it allows to create a continuous variation of the perception of balance transmitted by the foot to the central nervous system, which thereby has a continuous adaptation motor response, such as to improve the general muscle tone and the entire postural system, limiting the risk of joint lesions and avoiding chronic muscular pain.
It is in fact clear from what has been described above that the use of the posturology device, according to the present invention, entails a true postural gymnastics which unconsciously helps the user of the footbed to find an optimum posture at each step thanks to the constant variation of the feeling of balance perceived at each step.
In particular, the application of proprioceptive stimuli that modulate the signal of the receptor organs of the muscle and of the skin make the user react, unconsciously and step after step, to the continuous balance variations caused by the support provided by the rounded granules accommodated inside the footbed.
Therefore, the risk of inflammation and injuries is avoided, so as to avoid muscle and tendon fatigue caused by incorrect postures and so as to enhance the physical and athletic qualities of the user.
Another advantage of the orthopedic device according to the present invention resides in that the metatarsal tray thus structured is optimized to be worn even in high-heeled shoes without allowing an unpleasant accumulation of the rounded granules and together with the semirigid insert of the mid- foot provides perfect functionality, comfort and adaptability even in high-heeled shoes.
Another advantage of the orthopedic device according to the present invention resides in that the dual-layer structure, localized at the first three closed interspaces, produces greater comfort in the metatarsal region, which notoriously has a functional overload, protecting against excessive friction with the rounded granules 9, therefore, a better quality of the stimulus. Excessive friction would also produce, again to the detriment of the quality of the stimulus, muscle microcontractures of the foot and possible metatarsal pain.
Another advantage of the posturology device according to the invention resides in that it is extremely flexible and versatile, so that it can be used in any type of shoe.
The posturology device, particularly suitable for postural corrections, thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
All the details may further be replaced with other technically equivalent elements.
In practice, the materials used, as well as the contingent shapes and dimensions, may be any according to requirements and to the state of the art.
