Description

SPINE EXTENSION AND STRETCHING DEVICE

The present invention relates to devices for extending, stretching and exercising the spine allowing the user to massage and care for the back by lying on the device, in particular to work the spine.

The present invention aims to provide an extension and stretching and exercise device which is suitable for massaging the column in several places, in particular its extremities, being suitable for both the neck and the lower back simultaneously. .

PRIOR ART

Back massage devices are known which have a curved surface and allow a massage to be performed on a single zone, the neck or the back, such as those described in the documents USD877916 S1, USD820460 S1 or US20140115789 A1. For the sake of adapting to the area to be massaged, the device comprises a curved surface possibly equipped with massaging protrusions.

This solution is nevertheless unsuitable for massaging several areas and requires the use of several different devices, which implies an imprecise and complex installation to be set up by a single user. In particular, the user is not guided in his adjustment of the massage devices when he has to use several of them, and he can twist his back while positioning them, or position himself badly without realizing it. Moreover, the known devices are not both adjustable to operate for the neck or for the back and adjustable to adapt to the morphology of different users. Furthermore, the use of several similar devices instead of a large device such as that of the invention can lead to slippage and difficulties in maintaining position. Above all, no adjustable means specific to this activity is known in the prior art.

The object of the invention is to overcome at least some of the aforementioned drawbacks and to propose a stretching, extension and exercise device suitable for massaging both the neck of the user and part of his back, for example the lower back, and which is capable of combining the advantages of speed, simplicity and reliability for its implementation, and this, over a wide range of human morphologies.

In view of the foregoing, the subject of the invention is a stretching, extension and exercise board for the spine composed of two bases and a flat connecting element extending along a longitudinal axis between the two bases and adapted to connect the two bases together, each base comprising a base and a flexible panel detachably linked to the base, each flexible panel comprising a first face comprising a plurality of protrusions distributed over said first face and a second face facing the base opposite the first face and having no protrusion, the bases comprising means for holding the flexible panels in the curved position, in which position the flexible panels are curved so that the first face is convex so as to present the outward protrusions to allow the massage of a user, said holding means consisting of at least two parallel grooves provided in each base and adapted for the insertion of two opposite ends of the flexible panels.

Preferably, the bases comprise an upper base and a lower base, and the connecting element is adapted to mechanically connect the upper base to the lower base.

For example, the connecting element is mounted fixed in relation to the bases.

Advantageously, the connecting element is mounted in sliding connection with respect to the two of the bases.

According to one embodiment, the connecting element comprises an extension transverse to the longitudinal axis and that of the bases with respect to which the connecting element is mounted in sliding connection comprises a window in which said transverse extension is inserted in such a way to be able to slide longitudinally in said window, said transverse extension acting as a stop against two opposite edges of the window for the limitation of longitudinal sliding.

In one embodiment, each base comprises a mat through which at least one of the two parallel grooves is made.

Advantageously, the protrusions are at least partly formed of hemispheres approximately fifteen millimeters in diameter in diameter arranged longitudinally and spaced every approximately twenty-five millimeters apart on the first, convex face of each flexible panel.

The spine stretching, extension and exercise board may further provide that at least one of the flexible panels has a longitudinally extending through slot in the center of the flexible panel.

Preferably, the protrusions form at least two parallel rows and the through slot extends between the two parallel rows of protrusions.

The invention relates to a stretching, extension and exercise board for the spine in which the connecting element also has protrusions distributed longitudinally thereon.

DETAILED DESCRIPTION OF FIGURES

There illustrates the spinal extension, stretching and exercise board of the invention.

In the first embodiment illustrated in , we see that the extension, stretching and exercise board for the spine is divided into several parts on which the user comes to lie on his back.

The Spine 1 Spine Extender, Stretcher and Exerciser has two 3.5 bases. These are intended to allow stretching and extension of the user's spine. Indeed, the devices of the prior art only allow a partial massage of the column, either of a part of the back, or of the neck, which is contraindicated since the spine is a sequence of vertebrae which form a unit to work as a whole.

It is known that the exercises and devices allowing a complete work of the spine act very favorably on the mobility and the flexibility of this one, in particular with regard to the blockages and specific pains of the back.

It also allows you to perform more complete sets of exercises that reduce stress and help relieve or eliminate back pain.

As illustrated by Figures 2 and 3, the device for extending and stretching the spine 1 comprises a flat connecting element 7 extending along a longitudinal axis X, between the two bases 3.5.

The connecting element 7 allows a connection in length, along the X axis, and therefore according to the elongation in length of the column of the user who comes to lie on his back on the bases 3.5 and the connecting element 7.

The connecting element 7 extends between the two bases 3.5, which makes it possible to link them and to keep them in a good position of alignment, and prevents the user from doing exercises with his column curved, which can happen without him realizing it with the current devices, in particular because these are in several disjointed parts.

The connecting element 7 is thus adapted to connect the two bases 3.5 together.

The bases 3.5 may comprise an upper base 3 and a lower base 5, and the connecting element 7 is adapted to mechanically connect the upper base 3 to the lower base 5.

The lower base 5 intended for the spine, more particularly at the bottom of the spine, is larger, of the order of three hundred and eighty millimeters, than the upper base 3 intended for the neck, the order of two hundred and twenty millimetres.

Each base comprises a base 11.19 and a flexible panel 13.15 detachably linked to the base 11.19.

Provision is made, as shown, for example two bases 3.5, so two panels 13.15.

These panels 13.15 are placed on a base 11.19 by creating a shape of an arc in order to support the neck as well as the lower spine of the user.

Each flexible panel 13,15 has a first face, which is the top face as shown, and intended to accommodate the spine of the lying user.

The first face or upper face comprises a plurality of protrusions 16, 21 distributed over it.

These panels 13,15 are for example made of plastic. They are removable and easily removable for easy cleaning, to change the type of protrusions 16, 21, and also to reduce the size of the device 1 when it is stored.

Each flexible panel 13,15 has a second face opposite the base 11,19 opposite the first face and having no protrusion.

The protrusions 16,21 are approximately fifteen millimeters in diameter arranged longitudinally and spaced every approximately twenty-five millimeters apart on the first, convex face of each flexible panel 13,15.

The protrusions 16,21 form reliefs which can be of different sizes and shapes, and for example made of plastic.

It is of course possible to provide shapes of the protrusions adapted to the work of the back, other than shapes of massage balls, such as pyramidal, cylindrical, hemispherical shapes… and to plan to mix several different shapes.

The second side is the one that forms the underside of the panels 13.15 in the illustrations, and which faces the base 11.19 and indirectly to the ground.

Panels can be made from hard foam, like many existing products on the market, to form domed pads that can be added or detached from the 3.5 base and swapped out with shaped protrusion panels or in different styles or heights.

The pedestals 11,19 include means for holding 25,27,29,30 flexible panels 13,15 in the curved position.

These holding means 25,27,29,30 are illustrated more particularly in .

They allow the curved maintenance of the flexible panels 13,15, and constitute, like the connecting element 7, a novelty compared to the prior art.

In the curved position, the flexible panels 13,15 are curved so that the first face is convex so as to present the protrusions 16,21 outwards. This allows the massage of a user, to work his spine.

The holding means 25,27,29,30 consist of at least two parallel grooves 25,27,29,30 provided in each base 11,19 and adapted for the insertion of two opposite ends of the flexible panels 13,15.

There shows that the grooves 25,27,29,30 can in particular be slightly oblique thanks to an inclined rim 26 in each groove 25,27,29,30 with respect to the vertical, so as to accommodate the flexible panels 13,15 which fit into it by entering obliquely.

An advantage of the 25,27,29,30 grooves is that the user does not feel it when lying on them, unlike other solutions.

Several grooves can be provided, for example three parallel grooves, as illustrated, which makes it possible to easily adjust the height of curvature of the flexible panels 13,15, and thus adapt the curvature to the arch of the user, to his desire for comfort. , or to change exercise.

The bases 3.5 then each have four grooves to accommodate the panels 13.15, namely a single slot and three opposite grooves.

The panels 13,15 flex and fit into the single slot on a first edge, which is the longest edge if the plinth is trapezoidal in shape, while there are three slots on the opposite side to adjust the height of the arch formed by each panel 13,15 curved when in bending.

The three spaced grooves 25,27,29,30 in which the flexible panels 13,15 can connect make it possible to define three positions per base 3.5, which is generally sufficient to modify the height of the two arches formed according to the user preference, for a possible setting ranging from three hundred to five hundred millimeters.

Provision can also be made for the connecting element 7 to be mounted fixed relative to one of the bases 3.5. We can of course provide that it is fixed with respect to the two bases 3.5.

Advantageously, the connecting element 7 is mounted in sliding connection with respect to the two bases 3.5.

Thus, the connecting element 7 can be in sliding connection with respect to one of the bases 3.5 and fixed with respect to the other, or in sliding connection with respect to the two bases 3.5, or even fixed by compared to the two bases 3.5, all configurations being possible for this device.

The interest of a fixing relative to one of the bases 11,19 or both, is the absence of need for adjustment relative to this one or to these, while the adjustable connection allows an adjustment making the device adaptive.

According to one embodiment, in the case of the assembly of the connecting element 7 in sliding connection, the connecting element 7 comprises for example an extension 35 transverse to the longitudinal axis X. That of the bases 3.5 with respect to to which the connecting element 7 is mounted in sliding connection then further comprises a window 37 in which said transverse extension 35 is inserted so as to be able to slide longitudinally in said window 37.

We can thus define a longitudinal adjustment of the spacing of the bases 3.5 according to the size of the user.

The transverse extension 35 then acts as a stop against two opposite edges of the window 37 to limit the longitudinal sliding.

A plurality of windows can be provided, forming a notch, in which the transverse extension 35 can be inserted and blocked, at the option of the user, for maintaining the longitudinal adjustment of the distance chosen between the two bases 11,19 according to the window.

It is also possible to provide that the element 7 passes through at least one of the bases 11,19 and slides therein.

The free sliding junction of the connecting element 7 with respect to the bases 11,19 allows the two bases to slide freely back and forth depending on the size of the user.

Each base 11,19 may further comprise a mat 9,17 through which is made at least one of the two parallel grooves 25,27,29,30.

The mat 9.17 can be used to pad all or part of the space between the base 11.19 and the panel 13.15.

It can be maintained by a rim 31,33 arranged all around the base 11,19.

The back exercise board may further provide that at least one of the flexible panels 13,15 has a through slot 19,23 extending longitudinally in the center of the flexible panel 13,15.

The central slot 19.23 allows good positioning and support of the spine.

Preferably, the protrusions 16.21 form at least two parallel rows and the through slot 19.23 extends between the two parallel rows of protrusions 16.21.

Alternatively, provision can also be made for the connecting element 7 to be made in two complementary parts extending along the axis X from each base 11,19, for example two straps, complementary by mutually cooperating attachment means such as male and female elements, velvet and hooks, two adhesive parts, or even protrusions and holes...

It is in fact possible to provide that the connecting element 7 also comprises protrusions distributed longitudinally thereon.

These protrusions are, for example, balls, elongated bar-shaped bumps, etc. The user can thus benefit from an additional massage along the spine between the two 3.5 bases.

The protrusions of the connecting element 7 can also be adapted to cooperate with complementary protrusions or holes for maintaining and adjusting the connecting element and therefore the distance between the two bases 3.5.

In the lying position on the device 1, the user can remain still or add exercises, for example balancing between the two bases 3.5, this improves posture and reduces or even eliminates back pain. It is advisable to lie on the device before going to bed for best results.
