Description

The invention relates to a device for preventive and / or therapeutic bodybuilding of the abdominal belt.

Background of the invention

Back pain is one of the most common ailments in the world. The World Health Organization (WHO) estimates that in the world, 80% of people have suffered at least once in their lives. It is also one of the leading causes of medical consultation.

The socio-economic impact is significant, so the WHO has developed a neurosurgery working group to put in place a public education program to prevent back pain.

A key point of this prevention is the locking of the back which passes by the contraction of the abdominal and dorsal muscles so as to make the column and the pelvis integral. The axis of movement is around the hips.

Another point emphasizes the importance of bending your knees keeping your back straight; hence the importance of developing the abdominal-lumbar muscle strap: the ventral and dorsal belt to form a true muscle corset.

This can help to compensate for bad attitudes that in the long run become harmful and painful for the spine, as indicated on 14 September 2012 on its website, the Collaborating Center of the World Health Organization for Research and Development. Training in Neurosurgery: http://undospourlavie.org.

The abdomen is held only by the abdominal muscles which are divided into four types, whose fibers are oriented vertically, obliquely downward, then upward, and horizontally. This provides real protection, especially since there is no bone in the abdomen, and it becomes important to maintain these muscles.

Gymnastics, stretching and strength training can help keep your back healthy, but the stresses of life today leave little time for this activity.

Summary of the invention

The main purpose of the invention is therefore to propose an apparatus which, while being accessible to all and not very restrictive, allows, as a preventive or therapeutic measure and in just a few minutes a day, to obtain in the short term beneficial effects for its user.

• un socle;
• une barre s'élevant perpendiculairement au socle;
• une partie de support d'utilisateur fixée à ladite barre, cette partie comprenant une partie rotative comportant des moyens de maintien de pied, une paire d'armatures latérales et une paire de plaques incurvées fixées à une extrémité des armatures latérales ; et
• des moyens d'entraînement, pour entraîner en rotation la partie rotative par rapport au reste de la partie de support d'utilisateur.

This apparatus comprises:

• a pedestal;

Detailed exposition of the invention Principle of the device

The principle of the device is to rotate the entire body around the longitudinal axis of the latter. The pelvic girdle and the lower limb are maintained by a tubular structure adaptable according to the morphology.

• l'utilisateur s'installe debout sur la partie « rotative » 10 en mettant les pieds dans des étriers 5 ;
• il règle ensuite le système de maintien du bassin pour un confort optimal. Pour cela, il approche de lui les armatures latérales 10 (celles-ci pivotent librement) et ajuste leur longueur en fonction de celle de ses jambes. Il verrouille cette longueur par un bouton de réglage, suivant le même principe que celui de l'adaptation de la hauteur de la selle d'un vélo d'appartement. Ces armatures sont composées de tubes verticaux télescopiques et de plaques incurvées 14 prévues pour englober le bassin. Des repères de position par couleur identique de chaque côté permettent de régler les deux armatures à la même longueur. Les plaques incurvées, rigides et généralement métalliques, sont recouvertes de mousse pour éviter le contact du métal avec le bassin et prévenir des meurtrissures ;
• le maintien des plaques incurvées contre les hanches est assuré par le serrage d'une ceinture élastique munie d'une bande auto-agrippante, autour du bassin.
• l'utilisateur place ensuite les mains sur des poignées situées à proximité des plaques métalliques entourant son bassin. Dans cette position, il est prêt pour la rotation qu'il actionne au moyen du bouton rotatif (bouton de rotation).

The installation steps are as follows:

• the user stands upright on the "rotating" part 10 by putting his feet in stirrups 5;
• it then adjusts the pelvic support system for optimal comfort. For that, he approaches him the frames Lateral 10 (these rotate freely) and adjusts their length according to that of his legs. It locks this length by a knob, following the same principle as that of adapting the height of the seat of a exercise bike. These frames are composed of vertical telescopic tubes and curved plates 14 provided to encompass the basin. Position markers with the same color on each side allow the two frames to be adjusted to the same length. The curved, rigid and generally metallic plates are covered with foam to prevent contact of the metal with the basin and prevent bruising;
• the retention of the curved plates against the hips is ensured by the tightening of an elastic belt provided with a self-gripping band around the pelvis.
• the user then places his hands on handles located near the metal plates surrounding his pelvis. In this position, it is ready for the rotation it activates by means of the rotary knob (rotation knob).

The simple fact of keeping the body in its rectilinear axis during the rotation involves the abdominal belt (not counting the square of the loins and the spinal muscles which also maintain the column). There is only to fight against gravity.

Adjusting the exercise intensity

Preferably, the user also settles, once installed, the intensity of the exercise by turning a tilt rotary knob having for example 10 positions.

The larger the number chosen, the greater the angle of inclination of the body relative to the vertical.

The rotation starts when the selected degree of inclination is reached. The duration of rotation is generally chosen between 1 to 10 minutes using another rotary knob (tilt knob).

The intensity of bodybuilding is proportional to the inclination of the body. The beginner will begin with an inclination of 10 to 20 degrees.

The apparatus preferably includes an emergency stop button whereby the user will have the ability to stop the device at any time.

It can be provided that each incrementation of the rotary knob increases the inclination of 10 degrees by rotation about the hinge to the bar 18.

Similarly, it can be expected that each rotation time can be increased using the other adjustment button in steps of 1 minute.

Technical details in relation to the figures 1) Control electronics 1

The device is controlled / controlled by an XILINX brand programmable logic controller (CPLD) and reference card XC95144XL. The electronic card is contained in a housing.

2) Geared motors 2 and 3

Two identical geared motors can be used to perform both movements.

The side geared motor 2 allows to set the inclination and the bottom 3 to rotate the user on itself.

Geared motors 2.3 are for example of the brand LEROY SOMER and reference Minibloc MVAE 346.0 NU HM MUT 6P LS71M_P 0,12kW B14 230V 50Hz.

4) Electric cylinder 4

• LINAK LA 28 2 1 R 0 + 0 0 400 0 0 1.

An electric cylinder (visible in particular on the figure 4 ) can be used. For example, we can choose the following reference:

• LINAK LA 28 2 1 R 0 + 0 0 400 0 0 1.

5) Rotary Buttons (not shown)

These buttons can be arranged on the housing containing the electronic card 1. They are preferably easily manipulated and can have ten positions.

6) Emergency stop button (not shown)

Preferably, an emergency button is also provided, for example on the housing of the electronic card 1.

It is desirable that it remains within reach regardless of inclination and rotation.

7) Stirrups 5

They constitute foot insertion areas. It is preferable that the user only uses sports shoes for a good support of his feet.

The user just has to put his feet in the stirrups. This area serves only as "footrest" since the user is maintained by its center of gravity so by the area offering the most security: the pool.

8) Abdominal tightening belt (not shown)

The body of the user is held by clamping around his pelvis by means of an elastic belt provided with self-gripping strips. This belt encloses the curved plates 14 surrounding the basin.

9) Ball bearings 7

Two pairs of ball bearings can be used. One can choose for example the type is 6006 whose dimensions are d = 30 / D = 55 / B = 13.

10) Base

The base can be composed of an assembly of several tubes 8 and 19 resting on the ground. These tubes have for example a square cross section of 50 mm side.

11) The bar 18 is generally perpendicular to the base, that is to say vertical. It may consist of a tube similar to that of tubes 8 and 19. 12) The tilting part is the support part of the user, it is generally formed of tubes 9 having a square cross section of 50 mm and forming the non-rotating part (hereinafter referred to as "rest") and a rotating part comprising tubes 10 having a square cross section of 40 mm and which are articulated to a central tube 15 may also have a square cross section of 40 mm.

The rotating part preferably also comprises sliding tubes 6 which may have a square cross section of 35 mm.

Operation, effects and advantages of the apparatus according to the invention and its use

The strong point of the device according to the invention is primarily the configurable aspect of its actuators according to the budget and frequency of use of the purchaser.

Then comes the innovative and very effective nature of this system. Indeed, it provides a complete musculation of all the back and abdominal muscles in one exercise, regardless of the level of training of the person, especially as the latter chooses the angle of inclination and the rotation time. The difficulty can be increased as and when training, which allows to note the progress and motivate the user.

Simplicity and safety of use must also be emphasized. Features such as small footprint and moderate weight, allowing for easy handling and easy installation of the device, are appreciated. Finally, a weight machine requires some comfort to motivate regular use. These aspects are a guarantee of success for the purpose of such a device: a harmonious abdominal and dorsal bodybuilding, allowing to adopt a good posture in everyday life and to reduce certain back pains.

Use in the weight room requires professional quality equipment. The geared motor for inclination 2 is therefore recommended.

An individual will generally look for a lower cost. The tilt motor gearbox can then be replaced by an electric jack 4 (the latter being about 2 times cheaper).

It will be possible to apply the same reasoning for the transmission of the rotational movement. According to the budget of the purchaser, he will have the possibility of having the option "flexible transmission" 11, with set of pulleys 12 and belt 13 (cf. Figure 7 ). Indeed, to lighten the tilting assembly, the rotational geared motor 3 can be fixed to the frame 8. A flexible transmission 11 ( Fig. 8 ) will then be used to transfer the rotational movement to the tilting part 9.

The fact that the user keeps his body straight limits the risk of false movement, since there is no lumbar rotation, the trunk is rectilinear and the abdomen held muscularly. All this of course on the condition of gaining body muscle and not to relax undergoing gravity. People with back pain will appreciate this analgesic position and the fact of not having a load to wear. The simple fact of keeping the body in its straight axis during the rotation involves the abdominal belt (not to mention the square of the loins and the spinal muscles that also maintain the spine).

The apparatus according to the invention is characterized by rotating the entire body in the longitudinal axis. The pelvic girdle and the lower limbs are maintained by a tubular structure adaptable according to the morphology.

The user is standing, feet in the stirrups 5 on the "rotating" portion 10. It is maintained at the pelvis by curved plates, which are attached to two side frames consist of vertical telescopic tubes. The length of these frames is adjusted to that of the legs by a knob located on each of the armatures and identical position marks on each side to adjust the two frames to the same length.

The user then locks these settings by tightening a belt around the pelvis.

He finally places his hands on handles 16 located on either side of the metal parts 14 surrounding his pelvis. The position is ready for rotation.

The user turns the rotary knob to choose one of the programs that will define a tilt angle. He also chooses the rotation time by a rotary knob. This modularity allows a use adapted to the level training of each and a possible evolution in the difficulty of the effort. The apparatus is controlled by an electronic card 1, contained in a box, based on a programmable logic circuit.

It is better to have an emergency stop button so that you can stop the machine at any time.

A simple explanation is necessary to use this device since it suffices to remain in the rectilinear axis of its own body.

The user does not need to be accompanied to use the device according to the invention because it is autonomous at each step.

The public is also looking for a safe use, which is ensured by the right position of the body and the ability to stop the machine at any time.

Another advantage of the device according to the invention is its small size, often appreciated by the individual, but also in the weight room. It takes up little space because only the size of the base takes up space, the rest being in height.

Finally, the apparatus of the invention remains manipulable and lightweight (weight less than 50 kg) compared to other weight machines.
