Definitions
- the field of the present invention relates to a physical training machine for walking and running also known as a "treadmill”.
- Such machines are generally used in fitness rooms, hotels, sports clubs or even at home.
- Running is one of the most popular sports these days to keep in shape or to develop skills or qualities for playing other sports such as football, handball or basketball among others.
- running is a millennial activity, in our developed environment, outdoor running must often be practiced on rigid surfaces with low rebound, in particular on roads or paved paths.
- These training machines allow an athlete to train for running regardless of the weather outside.
- these machines can provide the athlete with a racing profile adapted to their performance and advancement in training, from beginners to high performance athletes.
- Various treadmills comprising rollers which are fixed in a frame, the rollers being surrounded by an endless rubber band which serves as an interface to the athlete's feet.
- shock absorbers known as a rubber "silent block” or air cushions (see for example WO92 / 11905).
- the runner For most people, the runner first places the heel of the foot and then unrolls the sole of the foot. It is therefore an attack on the ground with the heel of the foot, followed by a progressive course of the plant which will end in an impulse to carry out a new stride and so on.
- the foot When the foot is attacked by the heel, there is therefore no cushioning of the shock and the shock is amplified by the locking of the joints, the leg being stretched when in contact with the ground.
- the shock wave is not absorbed and will therefore spread throughout the body from the heel to the shin, the knee, the hip, the back to finish its course at the top of our skull.
- the foot Due to the inertia of the cushioning system of known training machines, the foot is exposed to shocks and "feels" the support as a stroke on a rigid surface.
- known systems do not or hardly adapt to runners with different physiognomy, in particular in terms of weight and bearing power.
- the object of the present invention is therefore to propose a physical training machine for walking and running which can reduce shock when the runner places his heel on the treadmill. Indeed, it is desired to obtain a running surface of the flexible soil, forest soil type.
- the present invention relates to a physical training machine for walking and running, comprising
- each roller is carried by a transverse axis the ends of which are connected by associated individual dampers interposed between the support structure and the transverse axis.
- the machine according to the invention may also include one or more of the following characteristics taken alone or in combination.
- the support structure has a rectangular shape, for example a rectangular box, and each individual shock absorber has a damping axis perpendicular to the plane defined by the support frame.
- Each individual damper can be a magnetic vibration damper, in particular with adjustable stiffness, or a hydraulic vibration damper, in particular with adjustable stiffness.
- each individual damper comprises a guide barrel perpendicular to the plane defined by the support structure, a piston arranged movable in translation in the guide barrel and a damper element one end of which bears against the bottom of the guide barrel and the other end of which bears against the piston.
- the individual damping element includes in particular a helical spring.
- the drive machine comprises a member for adjusting a prestressing force of each individual damping element.
- This member for adjusting a prestressing force comprises, for example for each of the ends, at least one adjustment bar, one longitudinal face of which bears between the ends on a face opposite that of the individual shock absorbers, the bearing force of the adjustment bar being adjustable.
- the drive machine further comprises an endless belt running around the set of rollers.
- the drive machine comprises at least one electric motor for driving at least one roller.
- the drive machine can further comprise a battery and a control circuit configured to be able on the one hand to switch the electric drive motor as a generator in order to allow the recovery of electrical energy and on the other hand to power the electric motor so that it drives at least one roller at a set speed.
- the diameter of the rollers is between 25mm and 35mm, in particular 28mm and in that the distance between two rollers is between 1mm and 4mm, in particular equal to 2mm.

- transverse axis 17 end for example in a ball joint 21 and are connected by associated individual shock absorbers 23 interposed between the support structure 13 and the transverse axis 17.
- the transverse axis 17 is fixed to the ball joint 21 for example by screwing or by welding.
- the ball joint 21 includes another hole or tapping to be able to accommodate an axis 25 of force recovery forming one 27 of the ends of an individual damper 23.
- the other end 29 of the individual shock absorber 23 is fixed to the support structure 13.
- the support structure 13 has for example a rectangular shape in the form of a bowl (see for example FIG. 4) with a peripheral strip provided with holes 31 allowing its fixing in the running plate 7 which comprises a housing of suitable size for this purpose.
- each individual damper 23 has a damping axis perpendicular to the plane defined by the support structure 13 or by all of the rollers 15.
- the shock absorbers 23 can be of several types. In particular, they can be passive or active to simulate different types of soil, adjustable or not in stiffness, for example to adapt to the weight of the runner, with or without an integrated sensor to deliver finer measurements on the runner's way of running.
- passive damper whose elastic stiffness is not adjustable, in particular with reference to FIGS. 4 to 7.
- each individual damper 23 comprises a guide barrel 33 perpendicular to the plane defined by the support structure 13, a piston 35 arranged movable in translation in the guide barrel 33 and a damper element 37, one end of which is in abutment against the bottom of the guide barrel 33 and the other end of which is in abutment between the piston 35.
- the piston 35 comprises for example a sliding pin 39 which slides in the guide barrel 33 and which is surmounted by a support washer 41.

- a sensor for example a strain gauge or a pressure sensor.
- Such sound sensors for example connected to the on-board computer of the display and control device 5.
- these sensors can make it possible to measure the weight of the runner and if necessary adapt the stiffness of the individual shock absorbers 23 as a function of this weight.
- each individual damper 23 can comprise a magnetic vibration damper, in particular with adjustable stiffness (for example that described in the article "Design of a magnetic vibration absorber with tunable stiffness" in the Nonlinear Dyn review of 26 March 2016 in the name of S. Bennachio, A Mahler, J. Boisson and C. Touzé) or a hydraulic vibration damper, in particular with adjustable stiffness (for example a hydraulic damper whose fluid contains magnetic particles which can be subjected to an electromagnetic field which changes the viscosity of the shock absorber fluid and therefore its stiffness).
