 With reference to these drawings, according to mn non-limiting embodiment in which the device of the invention is coupled to an ordinary rehabilitation cycle according to FIGS. 1 and 2. An electric gearmotor group with variable speed (2), remotely controlled by the user, drives the pedal (11) of the cycle (1) in a uniform rotational movement by means of a belt pulley system (3 and 4).

This rotational movement, regulated by the flywheel (7), is transformed into a translational movement communicated by two telescopic connecting rods, of different length (8 and 9). These connecting rods (8-9) are linked to the crank pins, formed by the axes (10) of the pedals (15) of said cycle (1), by means of a hook (6) carrying out two pivot vulture connections of the axes. orthogonal (10 and 14) of respective direction (Y and Z). A tensioner (15) is provided; its usefulness is explained in figure 3. The pivot connection of the hook (6) on axis (10) can be removed by a simple movement from bottom to top, the ends of the hooks (6) being elastic.

 According to Figure 3, there is a late-form (16) on which s: - nt fixed two slides (17 and 19) orientable around a vortical axis (22), tooth the spacing is adjustable thanks to a light oblong practiced in (16), cais not visible in this drawing. These slides (17 and 19) guide in translation the carriages (16 and 2G) driven by the telescopic balls (8-9) of different initial length, described in the preceding paragraph, FIGS. 1 and 2.

 the user is seated on an ordinary seat (23), independent of the system and which can be conveniently placed as a function of the length of his jasps and according to the type of rehabilitation sought.

 The elongated legs of the user rest per heels in the mobile heels (29) fixed on the carriages (18 and 20) visible in Figures 9, 10, 12 and 20.

 A tensioner (13), announced for the explanation of FIG. 1 and of FIG. 2, fixed to the cycle (i) on the one hand and to the small cliariot (18) on the other hand, makes it possible to regularize the movement of back and forth of the carriages (18 and 20). When the legs are close together, the tensioner is stretched; when the legs are spread apart, he is relaxed, his relaxation helping the legs apart.

 When the electric gearmotor group (2) starts up - variable speed, and controlled remotely by the user seated on his seat (23), the uniform rotation movement of the crankset (1 î) is transformed into translational movement thanks to to the two connecting rods (8 and 9) connected to the small and large carriage (18 and 20). The connecting rods (8 and 9) with the carriages (18 and 20) are connections with orthogonal axes, one of horizontal axis (Y) between (34 and 21), the other of vertical axis (Z) between (21 and 26) visible in Figures 10,11 and 12. The legs of the user driven by the carriages (18 and 20) therefore undergo a scissor movement whose amplitude varies according to the different adjustments of the slides ( 17 and 19), connecting rods (8 and 9), crank arms (11).

 According to Figure 4, the ens: tle of the device in linear configuration (17 and 19) horizontal, in the remote position, is obtained by loosening the axes (2,) of the slides (17 and 19) and sliding them in: the oblong slots of the support (16). See Figures 6, 7 and 8.

 The description of the use in this configuration remains identical to that (: ui was made for Figure 3. THE difference lies essentially in that the back and forth movements of the legs of the user are done from '' an initial position of the legs more spread apart.

 According to FIG. 5, the set carriage (18) and the connecting rod (9) are disconnected from the drive movement. Only the large carriage (20) continues to be driven in its rectilinear translational movement.

 The user stands upright, supported on a bar (24) fixed to theirs, one foot on the ground, the other foot in footwear (25) resting on the platform of the large carriage (20). The movement obtained on the leg corresponds to a simulation of walking.

The heel piece (29) and its support (28) fig. 10 can be removed or lowered to fac flex the knee and foot during exercise.

 According to Figure 6, we note in particular the two oblong lights.

 destiny: es to receive the axes (22) of the slides (17 and 19) for their possible adjustments.

According to Figures 7 and 8, we note in particular the slides (17 and 19) bevelled at their ends vis-a-vis, as well as the position of their axis (22) always for possible adjustments. The slides (17 and 19) are constructed in the manner of two lateral grooves, ensuring the guiding of the carriages (18 and 20) Figures 3,4,5,9,10 and 12.

 According to FIG. 9, there is the small trolley (18) constructed in the manner of a roller skate. I1 is intended to slide in (17) Figure 7 in particular.

This carriage (16) supports the heel piece (29) mounted on a tube (28) which can slide in (27). In (59), Figure 20, we will see that the tube (26) receiving the tube (26) is adjustable an orientation. In this figure, it is represented by the number (58)
The pin (27) is intended to fix the tube (28) sliding in (26). The height adjustable third heel (29) is in pivot connection with a vertical axis with respect to (28). The heel piece (29) in the form of a curved upwardly curved side is provided at one end with stop elements.

 According to FIG. 10, the description of the large carriage (20) is identical to that of the carriage (18) with regard to the fixing and the height adjustment of the heel piece (29). On the other hand, we notice an elongated platform that can be raised, but invisible on this drawing. This platform is intended to receive the foot shoe (25) of the user. Cespied (25) Figure 5, is wedged forward by the fixed stop (31) having the shape of a tilting toe clip, and at the rear by the adjustable stop (32) and having the shape of a clip.

 Figure 12 us against the same carriage (20) in its slide (1 c).

 According to Figure 11, we have a front and top view of the telescopic rods (8 or 9) connecting the crankpins to the carriages (10 and 18-20) by their tube (25). These connecting rods are essentially different by the presence of a tube (6) longer than the tube (9). for the rest, the beautiful ones (S-9) are strictly identical.

 At one end of the tube (8-9) is fixed an elastic hook (6) by a pivot link with vertical axis (14). In this tube (8-s) slides another tube (33) identical for the two connecting rods (8-9) whose axial position is adjustable. The ex trésity of the tube (33) is terminated by a yoke (34) receiving by a pivot link with a horizontal axis the ring (21). This ring (21) will adjust to the tube (? 6) of the carriages (18-20) following a pivot connection with a vertical axis Z.

 According to FIG. 13, we have a variant representation of the training code where the electric gearmotor groups (3S) with variable speed and controlled from a distance by the user, are directly integral with the supports (41) of the squirrels (35). Each geared motor (38) is provided with a single plate (37) with its crank pin (35) adjustable in spacing, to which is coupled each of the telescopic rods (36) and of identical length.

 When the gearmotor groups (38) start up in synchronization by phase opposition, the scissors (35), moving the axes (40) and coupled to the connecting rods (36) thanks to the axes or marie tons ( 49) figure 20 of articulation in spherical connection, fixed on the lateral part of said slides (35), are moved back and forth more or less rapid depending on the speed chosen.

 According to FIG. 14 in correspondence with FIG. 13, we additionally kill the slide assembly (35), parallel axis (40), slides (41), support platform (43) of slide (41) provided with means lifting as jack (45). This jack is disposed between the slide support platform (43) (41) and a second support platform (44). The end of the platform (43) and of the platform (44) opposite the jack (45) is articulated around a transverse axis (46). The carriage (35) is coupled to the connecting rod (36 ) by articulation axis (49), FIG. 20, and at the other end to the @ neton (39) duplateau (37) of the electric geared motor group (35). This means that the back-and-forth, when the gearmotor (38) is put into motion, is also carried out on an inclined plane. An axis (42) is provided for orientation, spacing adjustment and fixing of the slide (41).

 According to Figure 15, the slide device (41) criss-cross (35) is also designed in the manner of an open in its upper Matie and in one of its side parts. These openings are provided so as not to impede the movement back and forth when the heel extension tube (29) is fixed on the slider (35) on the one hand, and on the other hand when the connecting rod (36), previous figure, is ae- coupled to the axis (49) of the slide (35) in sherical connection in figure 20. This slide device (41) has along its length two parallel axes (4C) fixed to the front and to the rear supporting rings or sleeves integral with the base of the slides (35). All of which acts as a slide.

 According to FIG. 16, we have a representation of the second traveling mode, where the electric geared motor group (47) with variable speed controlled by stance by the user is fixed between slide support (41). I1 has its transverse shaft on which, on each side of said geared motor (47) is fixed a plate (37) with each its crankpin (39) Figure 13, in opposite direction and adjustable ea spacing, which allows an amplitude greater of the back-and-forth. Two telescopic connecting rods (36), of the same length, connect the slides (35) thanks to the spherical connecting axis visible in (49) figure -20, to the crankpins (39) of the gearmotor plates (37) (47). When the gearmotor group (47) is started up, there is also a back and forth movement, of greater or lesser amplitude, according to the adjustment of the connecting rods (36) and the crankpins (39) of slides (41) fi gure 14. The advantage is to have only one gearmotor group (47) without synchronization means as in the representation in figure 13.

 According to Figure 17, we have a representation of the slide support device (41), slide (35) with its connecting rod (36) coupled on the one hand to the crank pin (39) of the plate (37) of the electric geared motor group (47) , and on the other hand to the scissor (, 5) by an axis (49) Figure 2C.

 Figure 18 shows us in correspoadance Figure 13 in another configuration of use of the whole of the electrical gearmotor group device (38) with their plates (37) and their crankpins (39), their telescopic connecting rods (36) coupled to said gearmotors (36) and trolleys (35), thanks to the crankpins (49) Ligure 20.

 The two opposite ends are raised by means such as jacks (45) thanks to the articulation around a transverse axis (46) at the end connecting the tiltable lateform (43) and a second platform (44) .

 On the tilting lateforne (43) is fixed the gearmotor (38, and the connecting rod (36), rod (35) slide (40) slide support (41) assembly. The latter set retained by a fixing and orientation (42) between (41) and (43). The second platform (44) has at the bottom a fixing axis (48) intended to receive the oblong light of a third support platform (16) figure (6), for any adjustments.

 According to FIG. 19 corresponding to FIG. 16 in another configuration, this no longer leaves the opposite ends, FIG. 17, yes are raised, but the most distant.

 To do this, the entire slide support device (41), scissors (35) connecting rods (36), r: geared motors (38), first platform (43) second platform (44) has sabi a rotation of 180 degrees thanks to the axis (48) at the bottom of the second platform (44) pivoting in the oblong lumen of the third platform (i 6). The advantage of this system is to have only two trics (45) at the most distant end or opposite for the lifting of the whole device designed to receive the heel pieces (29) adjustable in orientation indicated in figure 20 in (59).

 Figure 20 shows a variant of the previous arrangements. L: configuration described in this figure allows the following rehabilitation exercise: the user seated on the seat (23) lengthens his legs horizontally, the heels placed on the heel pieces (29). The legs will also undergo a back-and-forth movement as in Figures 3 and 4, when the electric gearmotor unit is started (2) in Figure 1, but with the difference that this scissor movement is also done according to the plans inclined, facing or back to back. See also Figures 14-18-19.

 The device is joined by a base (16) provided with 8 yokes (53 to 56) distributed symmetrically. A plate (5G) provided at its ends with two tubes (51) to (52) receives a slide support (4í) orientable around an axis (42).

 The plate (50) can be fixed in different ways on the support (16).

Movement in a horizontal plane:
- End (52) in clevis (55), end (51) in (55).

 - End (52) in clevis (54), end (51) in (56).

Movement in an inclined loop:
- End (52) in yoke (53), end (51) raised by ladder (57)
spun on (16) in yoke (55) or (56) - End (51) in yoke (54), end (51) lifted p - ladder (57)
fixed on (16) in the yoke (55) or (56)
- End (51) in yoke (56), end (52) rewashed by (57) fixed in
(54) or 53
- End (51) in clevis (55), end (52) relave by (57) fixed in
(54) or (53) the same configuration applies symmetrically.

 Figure 21 is a representation of the lifting scale (57) fixed on (51) or (52) and in (54) to (56) by axis rods (60) held in place by a pin. View F shows the articulation of the tube (58) with respect to the cuff (35), the adjustment of which allows the heel support (29) to be kept vertical, when the back-and-forth is effected on an inclined rising plam or descending. This adjustment can be made by means of (59) having radial grooves allowing good stability of the link @ to be obtained. The description of the carriage (35), sliding axes.

re (4Ci) was previously made figure 15.

 C @ tte variant proposed by Figures 20 and 21 uses the device of Figure 1 and 2 with the rehabilitation cycle (1) and the electric geared group (2) driving the telescopic rods (8 and 9).

 By cons, the carriages (i6 and 20) and the slides (17-19) are replaced by ~ the water grout device (35) axes (40) mounted on (41), described in Figures 13, 14, 15 and following. The connecting rods (6 and 9) are coupled to the slides (35) by axis (49) of articulation in spherical connection, fixed on said slides.
