Definitions
- the invention relates to the technical sector of analysis and measurement devices for biomechanical medical use in particular, medical and sports.
- Apparatuses which make it possible to measure the angular variations between in particular the tibia and the femur, corresponding in particular to the flexion and extension movements during walking. On the other hand, such devices give no indication of the support forces.
- the measurement does not differentiate the support of each leg, which is not a problem for the analysis of the race, because there is hardly ever a simultaneous support of the two legs, the support being essentially monopodal, but this which is prohibitive for walking, given that there is systematically a simultaneous support of the two legs, the support being of the bipodal type, - the measurement of the tangential forces is impossible.
- the object of the invention is to remedy these drawbacks in a simple, safe, efficient and rational manner.
- the problem which the invention proposes to solve is to offer physiologists and orthopedists a solution capable of measuring the vertical and horizontal forces, that is to say the tangential forces, of the supports on the ground, in particular of several steps successive, by advantageously but not limitingly separating the supports exerted by the right leg of those exercised by the left leg.
- a device for measuring the forces exerted by each leg during walking which comprises at least one assembly equipped with a motorized treadmill, mounted in a chassis constituted by a rigid structure receiving the various elements of the belt for its training, said structure being carried by force measurement sensors secured to a common plate for support on the ground, in order to measure the vertical and tangential forces.
- the device comprises two independent assemblies arranged one next to the other, in a parallel manner, for correspond to each of the legs, each of the assemblies being subjected, in a separate manner, to the force measurement sensors carried by the common ground support plate.
- each of the structures comprises an upper part in the form of a rectilinear beam, arranged for the mounting of an endless belt mounted in combination with drive rollers fixed to each end of said beam, said structures being arranged opposite one another, so as to position the belts in an almost contiguous manner, avoiding contact between the two carpets.
- the sensors can be quartz force sensors capable of measuring the three components orthogonal to a dynamic force acting in any direction.
- the sensors are fixed to each of the ends of each chassis.
- FIG. 1 is a plan view of the device.
- FIG. 2 is a view in longitudinal section considered along line 2.2 of FIG. 1.
- Figure 3 is a cross-sectional view taken along line 3.3 of Figure 2.
- the device comprises two independent assemblies (E1) and (E2), arranged one next to the other, in a parallel manner.
- Each assembly (E1) and (E2) constitutes a support frame (1), shaped for mounting a motorized conveyor belt (2).
- Each of the chassis (1) is subject to force measurement sensors (3) carried by a common ground support plate (4).
- each of the chassis is shaped to constitute a rigid structure and isolated in space, in order to be able to effectively measure, the vertical and tangential forces in combination with the sensors (3), in complete independence of friction.
- each of the structures comprises an upper part in the form of a rectilinear beam (5), having a slot (5a) for the passage of the endless belt (2a) of the conveyor belt (2).
- the upper strand (2b) of the strip rests on a plate or sole (5e) whose contact surface with the strip is treated to improve sliding.
- This beam (5) can be in one piece or composed of two parallel beams (5b) (5c) delimiting the slot (5a), the beams being coupled two by two, by a lateral beam (5d).
- the beam (5) whatever its embodiment, can also be coupled at its underside and, on the side of its outer arm, to another spar (6), whose essential function is to increase still the rigidity of the beam (5).
- this spar (6) projects beyond the transverse faces of the beam (5) and may have support flanges (7) for mounting the drive rollers (8) and (9) of the belt (2).
- one of the rollers (8) for example, is motorized.
- the roller (8) can directly integrate a motor, or be coupled by any known means and suitable for an independent motor (10), so as to drive each of the belts (2) in a direction opposite to that of walking.
- the entire chassis as defined rests on the support plate on the ground (4) by means of the sensors (3).
- the underside of each of the beams (5) has a rectified rail (11) on which one of the ends of the sensors (3) is fixed.
- the other end of the sensors is fixed on parallel rails (4a) of the common ground support plate (4).
- the two chassis are strictly identical and are arranged opposite one another in a parallel manner, by being coupled to the common plate (4), by means of the sensors (3), leaving a very small space. It follows that the treadmills (2), after mounting on the corresponding drive rollers (8) and (9) are independent, but are almost contiguous.
- the latter are advantageously constituted by quartz force sensors, capable of measuring the three orthogonal components of a dynamic or almost static force, acting in any direction.
- these sensors can be of the type sold by the company KISTLER INSTRUMENTS.
- the entire device as described is controlled by any system for processing and analyzing the measurements taken. Provision is also made, to stiffen the whole of the beam (5), to connect the two parallel longitudinal members (5b) (5c), with spaced vertical bars (12). Note that the stiffness bars of the beams of the two opposite assemblies are fixed two by two regularly alternately, to reduce the space between said two beams, after coupling on the common ground support plate in combination with the sensors
- the device finds an application essentially for measuring the forces in the case of the race where the supports are essentially of the monopodal type.
