Abstract

A device for adjusting the height of a bar to suspend it by keeping feet on the ground with the hips and knees bent at right angles to rehydrate its intervertebral discs. The invention relates to a device for quickly and accurately varying the height of a bar, prevent rotation and sliding so that the user can hang safely. The device consists of two lateral uprights, a suspension bar and two shims. The two identical amounts are to be fixed on each side of the door frame or the walls of a corridor or in the corner of a room by the addition of wedges at 45 °. They are provided over the entire length of their inner face of a vertical central slide and regularly spaced transverse grooves. The two shims are positioned in the grooves of the uprights according to the chosen height. They provide adjustment and vertical locking of the bar positioned on them. The protuberance of the wedges and the difference in height of the indentations of the ends of the bar allow by turning to refine centimeter its vertical adjustment and ensure the self-locking device. Thus the user can hang from a bar ideally placed in height. Once his suspensions are made he reposition the bar in the up position to free the passage. This device according to the invention is mainly intended for the rehydration of intervertebral discs by suspension at home or another place to prevent and relieve back pain.

Description

The present invention relates to the field of public health, more particularly the prevention and the relief of back pain, at home, at the workplace or at another place. The present invention relates to a device for making suspensions by keeping feet on the ground, hips and knees bent at 90 ° to reverse the compression action of gravity on the intervertebral discs to rehydrate. Today back pain has become a fatality that few people escape for lack of effective prevention. The main cause of back pain is progressive dehydration of the intervertebral discs, which causes their compression. Indeed when we are standing or sitting under the action of compression due to gravity, our intervertebral discs dehydrate gradually during the day. During the night, following the horizontal position our discs recover the lost water. We can assume that gradually during the day the damper role of our records becomes less and less effective which is harmful to their pressure distribution. In addition, with age, nocturnal recovery becomes incomplete, so our discs undergo during our life a progressive dehydration which unfortunately results in their loss of functionality and their premature aging. To slow down this aging, it would be necessary from time to time during the day to reverse the action of gravity on our intervertebral discs to rehydrate them. There are some paramedical devices dedicated to this purpose and that can be used at home. The reversed board, the Nubax Trio and the Soulagedos are the best known. They reverse the action of gravity on the spine by different mechanisms. For the inverted plank, the user sits obliquely upside down while being held by the feet, so the action of gravity is reversed. For the Nubax, the user kneels in an apparatus where his pelvis is blocked by a strap, and his arms are by two supports placed under the armpits. When he leans forward, traction is exerted on his column by a lever effect. For the Soulagedos, the head is placed in a support, and the stretching is done from the cervical ones while sitting or standing. These three devices are dedicated to reverse the action of gravity on the intervertebral discs, but they nevertheless have major disadvantages. Their use is both special and specific. Their price is of the order of 300E or more and they are relatively bulky so difficult to stoker. These disadvantages mean that few people get them. There are other devices to reverse the action of gravity on the spine, but they are professional and can not be used by a particular at home. The best known are the traction table and computerized neurovertebral decompression table. 3037813 - 2 - There are therefore few functional devices that can be used at home to reverse the action of gravity on the spine in order to rehydrate its intervertebral discs, an action that can be called "hydrometric stretching". These hydrometric stretches can also be done by hanging at a bar. 5 In this case, the hips should be bent at 90 ° in order to release the abdominals, ie the legs stretched out with their feet on a hold, or keeping their feet on the ground with the knees flexed as well as the hips at 90 °. Weight bars for doing push-ups at home can be used to achieve this kind of suspension. The suspension while keeping the feet on the ground is by far the most functional, as it does not require a large hold or other stakeholder to support the feet in place of the hold, and the performer does his stretches safely, because he keeps his feet on the ground. On the other hand to hang the legs bent at 90 ° while keeping feet on the ground, requires a height of bar substantially equal to the size of its user. On the market we find many types of bars for doing tractions at home. Some are to be fixed on the top of the door jamb and are not adjustable in height. If this height is suitable for doing tractions, it is not to make suspensions by keeping feet on the ground hips and knees bent at 90 °. They will not be able to allow us to do hydrometric stretching. A well known device consists of a telescopic bar disposed on the door frame 20 of a door or between two walls. This telescopic bar by its screw system ensures its maintenance by compression against the amounts of the door jamb or the walls of a corridor. Unlike bars attached to the upper part of a door jamb, it can be installed at the desired height for hydrometric stretching. But its installation is not simple and it takes a while. As a safety measure it is delivered with anti-rotation screws which it is imperative to use, because under the action of the weight of its user the bar has a tendency to slip and to continue to screw or even to unscrew if it is used in the wrong way. So to use the bar, it will be better each time screw it and probably unscrew it to remove it, which can quickly become binding. Another attachment of this bar consists of spoilers screwed on the inside of the uprights and intended to receive the ends of the bar, making it safer and more easily removable for use. In this case, the spoiler attachment height gives the bar height. If you want several bar heights, it will increase the number of spoilers. This type of attachment due to spoilers prevents the bar from sliding along the uprights but does not prevent it from rotating when it is used, so it is always advisable to use anti-rotation screws.

To make push-ups the bar can be placed at a height high enough to not disturb the movements of everyday life in an apartment, so you can fix it properly and leave it in place. On the other hand, a bar placed for hydrometric stretching is lower (heights of its users) and must therefore be moved with each use. The time lost in the installation and removal of this type of bar may discourage hydrometric stretching, especially since it must be ensured that the bar holds well before hanging. This type of bar is an effective solution for doing pull-ups at home, but is not the right solution when the bar needs to be moved several times a day. There are also porticos where you can vary the height of the bar to hang but their size, their weight and their aesthetics make them more likely to be installed in a gym than in an apartment. We conclude that there is no truly functional device for performing hydrometric stretching for a person or family at home or for a group of people in a workplace where sizes may vary between larger and smaller. the smallest of several tens of centimeters. The present invention therefore aims to remedy these drawbacks. More particularly, the present invention aims to provide a device usable at home or at a workplace, which allows each user to quickly adjust the height of a suspension bar to its size to make hydrometric stretching safely and to move it just as quickly so that it is not embarrassing. According to a first feature the device comprises two identical lateral supports to be fixed on the door jamb or on either side of the walls of a corridor or in the right angle constituted by two walls with the addition of calluses to 45 °. These amounts have over the entire length of their inner face, on the one hand a central slide intended to receive the ends of the bar and the wedges it blocks laterally and on the other hand a regularly spaced repetitive system intended to receive the shims. Thus the wedges allow the vertical locking of the bar and a first adjustment of its height. This repetitive system is materialized by transverse grooves of the width of the uprights, or according to a variant, by holes in the slide. The wedges have protuberances, or alternatively, lugs. The protuberances of the holds have two functions. They make it possible to block the wedges laterally in the wings and also to adjust the vertical adjustment of the bar by turning the wedges in the transverse grooves by a height corresponding to their size. The ends of the bar have indentations of different sizes, which also have two functions. They make it possible to block the shims in depth in the slide and also because of their difference in height, to adjust by turning the bar up its vertical adjustment. The combination of these three adjustment systems of the bar allows to refine its height to centimeter along the length of the uprights. So once the amounts fixed and the bar cut to the right length, to suspend in order to do hydrometric stretching, the user or users just have to place the wedges in the grooves chosen. They can possibly refine the height adjustment of the bar using the possible reversals of the wedges and the bar. Once its hydrometric stretches are complete, the user moves the bar and shims up to free the passage before another use. This handling only takes a few seconds each time and the bar remains available at hand ready to be used again. Unlike telescopic bars, our bar can not turn under the weight of its user. Indeed, because of its indentations our bar rests by a flat surface on the 10 wedges. In addition its flat central part adapted in thickness to the slides into which it is inserted, also prevents it from pivoting. Similarly it can not slip because the holds are not likely to come out of the grooves due to the notches of the bar which under the weight of the user remains well wedged on the holds behind the scenes. Our device can, contrary to all devices for the prevention of back pain, be of ecological interest and of sustainable development since it can be made entirely of wood. Another interest is its customizable aesthetic appearance. The bar is made of ash, hardwood and soft. The uprights and wedges are made of hardwood: oak, ash, elm, chestnut, cherry ... These woods can be treated natural or painted to adapt to a rustic or modern habitat. Our suspension bar can also be used for push-ups or other weight-training exercises because of its strength and attachment well above that of a telescopic pull bar. But its main interest is its functionality of use and its cost of manufacture. The attached drawings illustrate the invention: FIG. 1 represents a partial profile view of the internal face of an amount.

Figure 2 shows a slightly side view of a wedge with protuberance in its two possible positions in a groove. Figure 3 shows the end of a bar seen from the front in its two possible positions on the protrusion of the wedge. Figure 4 shows the bar in cross section.

Figure 5 shows an amount of the hole variant. Figure 6 shows a wedge with pins corresponding to the variant of the uprights with holes. With reference to these drawings, the device comprises two identical lateral uprights (1) whose inner face is provided with a longitudinal central slide (4) intended to receive the bar (2) and the wedges (3) which it ensures the lateral locking. . This inner face of the uprights (1) is also provided with a system for locking and vertical adjustment of the bar materialized by transverse grooves (5) spaced regularly by a few centimeters and intended to receive the shims (3). ). Thus the shims (3) placed in the transverse grooves (5) ensure the locking and the first vertical adjustment of the bar (2). The shims (3) by turning allow to vary the bar height of the height of the protuberance (6) is 2cm. The bar (2) has at its 5 ends notches (7 and 8) which allow to block the shims (3) deep in the slide (4), making the assembly a self-locking system. The difference in size of the indentations (7 and 8) of the ends of the bar (2) also allows its turning to vary its height of the difference in the size of the notches (7 and 8) is 1 cm. These three adjustment systems make it possible to adjust the height of the bar (2) to the centimeter on the length of the uprights (1).

To avoid sharp angles the uprights (1) are bevelled at their low end, as their edges between the inner face and the side faces are rounded. The edges (9) of the bar are rounded to favor its holding by its users. The central portion (10) of the bar is flat and its thickness corresponds to the width of the slide (4). The variant with the parts (1 ', 3', 5 ', 6') will have the same operating principle.

By way of non-limiting example: the uprights (1) or (1 ') will have dimensions of the order of 550 mm for the length, 70 mm for the width and 24 mm for the thickness. The slide (4) will have the length of its amount (1) or (1 '), its depth will be of the order of 12mm and its width of the order of 23.2mm. The transverse grooves (5) will have the length of the width of their upright (1) and the dimensions of the order of 12 mm for the depth and 10 mm for the height. Their centers will be spaced 40mm apart. - The shims (3) have a thickness of the groove depth (5) is 12 mm and a height of 9.9mm adapted to the height of the grooves (5) for a length of 60mm. The protuberances (6) of the wedges (3) will have a width of 23 mm adapted to the slide (4) and a height of 20 mm. -For the variant, the holes (5 ') will have a depth and a diameter of 10mm and their spacings will be spaced 30mm. The shims (3 ') will have a length of 80mm, the lugs (6') will have a diameter and a depth of 10mm and their spacings will be spaced 30mm. The outer edges of the lugs (6 ') will be placed at 10mm and 30mm from the ends of the shim (3'). 30 -The bar (2) will be precut on one side and the indentations (7 and 8) will have dimensions of about 12mm for their depth and 5mm and 15mm for their height. The bar will have dimensions of about 50mm for the width and 23 mm for the thickness. Its length for the standard version will be of the order of 900mm, which allows an adjustment to all the doors of the market. It will be adjusted in length according to the difference between the amounts (1) or (1 ') fixed. 35 -Long versions can be envisaged, just adapt all the dimensions of parts 3037813 - 6 - to physical constraints. Another variant may be envisaged with shims (3) of less thick metal and transverse grooves (5) less thick and less spaced. The device according to the invention is particularly intended for the rehydration of intervertebral discs by suspension at home, at work or elsewhere, to prevent and relieve back pain.
