pull rope 60.

  The mounting rod 22 is capable of being supported on a floor surface and it has right and left parts opposite to each other in a longitudinal direction, as well as an intermediate part interposed between the right parts and left. In this embodiment, the physical culture device further comprises a support rod 23 arranged to be spaced from the mounting rod and parallel to this mounting rod and a support bar 21 extending in the first transverse direction for interconnect the intermediate part, as well as the support rod 23, so as to form a support frame 20 in the form of an I. The physical training device may also comprise a mounting seat 30 disposed on the support frame 20. The mounting seat 30 has a transverse plate 31 and front and rear side plates 32, 33 extending longitudinally from the front and rear edges of the transverse plate 31. The front and rear side plates 32, 33 have bottom ends which are fixed respectively to the mounting rod 22 and to the support bar 21. A reinforcing plate 34 extending obliquely has an upper end ure connected to a junction between the transverse plate 31 and the rear side plate 33, and a bottom end fixed to the support bar 21, so as to strengthen the connection of the

  mounting seat 30 with support frame 20.

  The right and left shafts 35 define first and second axes respectively and have upper and lower right and left ends. The lower right and left ends are fixed to the intermediate part of the mounting rod 22 respectively near the right and left parts. The upper right and left ends are respectively opposite the lower right and left ends in a respective direction among the first and second vertical directions which are parallel to the first and second axes respectively. The shafts 35 on the right and on the left are arranged on the same longitudinal plane and are inclined respectively towards the right and left portions of the mounting rod 22 in a substantially V-shaped configuration, such that the cones 35 of right and left form the same angle with the surface of the floor.

  right and left around the first and second axes respectively and to be able to rotate relative to these trees on the right and left. The right tubular member has upper and lower right tubular parts 401, 402 opposite one another in the first vertical direction. The left tubular member 40 has upper and lower left tubular parts 401, 402 opposite one to the other.

  the other in the second vertical direction.

  The right pedal 42 has parts of the proximal and distal right opposite one another in a first radial direction relative to the first axis. The left pedal 42 has proximal and distal left portions opposite to each other in a second radial direction relative to the second axis. The right and left proximal parts are anchored on the upper tubular parts 401 of the right and left and rotate respectively with these parts

tubular 401.

  The pulley member 53 is arranged to be capable of rotating around a third axis, and it is spaced from the intermediate part of the mounting rod 22 in a first transverse direction relative to the longitudinal direction. The pulley member 53 has upper and lower major friction surfaces, opposite one another, and a groove or crown 531 arranged to surround the third axis and to connect the upper and lower main friction surfaces. The gente 531 has an annular groove extending inwards and radially to receive the cable or

the pull rope 60.

  The traction cord 60 has first and second ends fixed respectively to the lower tubular parts 402 on the right and on the left, as well as an intermediate friction segment interconnecting the first and second ends and

  arranged to be wound around the gente 531.

  When the lower right tubular part 402 rotates around the first axis in the direction opposite to that of the clockwise, under the effect of an external and lateral walking action of the right foot of a user stepping on the pedal right 42, the second end is pulled by the first end to force the lower left tubular part 402 to pivot in the opposite direction to that of clockwise, so as to produce a resistance to a walking action towards the outside and side of the user's left foot walking on the left leg 42 to move the lower left tubular part 402, so as to rotate it clockwise via the upper left tubular part 401 Thus, the physical training device according to the invention simultaneously allows walking and skiing exercises, while ensuring a damping effect without

  that it is necessary to provide a hydraulic cylinder.

  A mounting pin 54, provided with a threaded part 541, is disposed on the support bar 21, and it extends along the third axis, so as to be mounted in rotation with the pulley member 53. A support block 70 of generally rectangular shape is also disposed on the support bar 21 near the support bar 23, and the mounting pin 54 extends upwardly through the support block 70. This block support 70 is provided to allow the pulley member 53 and the cable or traction cord 60 to be substantially on the

  same plan, so as to facilitate operation.

  The physical training device further comprises upper and lower friction members 56, 57, a thrust member 51, a lower cover member 52 and a friction adjustment member 55. The upper friction member 56 is mounted on the mounting axis 54 and is movable along the third axis. The upper friction member 56 has a downward friction braking surface disposed opposite the upper main friction surface of the pulley member 53 and movable towards this friction surface, so as to create a traction force or pull applied to the upper main friction surface, so as to produce an increased tensile strength of either of the first and second

  ends of the tracion rope 50.

  The lower friction member 57 is mounted on the mounting pin 54 and is disposed on the opposite side of the pulley member 53 relative to the upper friction member 56. The lower friction member 57 has a surface up friction friction brake located opposite the lower main friction surface of the pulley member 53, so as to create a pull or pull force applied to the lower main friction surface, when the upper friction 56 is moved to the pulley member 43, so as to bring the lower main friction surface into friction contact with the friction braking surface upward, so as to produce increased tensile strength of the one of the first and second ends of the rope

pulley 60.

  The thrust member 51 is mounted on the mounting pin 54 and is movable towards the friction surface

  main upper, along the third axis.

  The pushing member 51 is provided with a periphery surrounding the third axis and a retaining wall 511 extending from the periphery in an axial direction parallel to the third axis and towards the lower friction member 57, so as to house the pulley member 53 along and inside the

  upper and lower friction members 56, 57.

  Thus, the traction rope 60 is prevented from escaping from the gente 531 of the

pulley 53.

  The lower cover member 52 and fixed to the support block 70 and the mounting pin 54 passes, in sequence, through the lower cover member 52, the lower friction member 57, the pulley member 53, the upper friction member 56, and the thrust member 51, so that the threaded portion 541 will protrude from the member

thrust 51.

  The friction adjustment member 55 is disposed outside of the thrust member 51 and abuts against this thrust member 51. The friction adjustment member 55 is screwed onto the threaded part 541 of the mounting pin 54, which projects from the thrust member 51, so that the screw movement of the friction adjusting member 55 along the third axis brings the friction braking surface down of the upper friction member 56 toward or away from the upper main friction surface of the pulley member 53, so as to increase or decrease the

tractive force.

  The physical training device also comprises link arms 44 on the right and on the left and levers 412 on the right and on the left. The link arms 44 on the right and on the left respectively have coupling ends 441 on the right and on the left coupled to rotate with a respective one of the lower tubular parts 402 on the right and on the left, and connected ends 442 on the right and of left extending respectively from the right and left coupling ends in two radial directions relative to the first and second axes respectively, and connected to the first and second ends of the pull cord 60, respectively. The connected ends 442 of right and left are arranged so as to be spaced from the floor surface or

the mounting rod 22.

  The levers 412 on the right and on the left fixed to rotate with a respective one of the upper tubular parts 401 of the right and of the left and of the seat ends of the right and of the left extending respectively from the anchoring ends of the right and on the left in two radial directions relative to the first and second axes, respectively, and supporting the right and left pedals 42, respectively. In addition, right and left damping or stop pads 43 are respectively arranged on the right and left anchoring ends opposite the right and left pedals 42 to come into abutment against the rod. support 23, when the levers 412 on the right and on the left move downward, so as to perform a shock absorption function

or depreciation.

  In service, when the user alternately actuates the pedals 42 with the two feet, his weight being placed on one of the feet, the pedal 42 carrying most of the user's weight will be pressed down. In the embodiment shown in Figures 4 and 5, the left pedal 42 is pressed down. As the right and left pedals 42 are pivotally mounted on the right and left arres 35, when the left pedal 42 is pressed, the upper left tubular part 401 fixed to the left lever 412 rotates around the second axis in clockwise, so as to bring the left lever 402 with the left pedal 42, to pivot outwards and laterally with respect to the support bar 21, until the shoe stop 43 on the left lever 412 abuts against the support bar 23 or until the user switches or puts his weight towards the right foot. The movement of the left pedal 42 forces the traction cord 60 connected to the link arm 44 on the left on the lower left tubular part 402, to pull the right link arm 44 on the lower right tubular part 402 towards the inside with respect to the support bar 21, via the pulley member 53 (see FIG. 5). Referring to FIG. 6, when the user places his weight with his right foot to press the right pedal 42 downward, a resistance resulting from the traction of the traction cord 60 on the right link member 44, is encountered. When the user rotates the right pedal 42 along the right lever 412 anticlockwise around the first axis, the right pedal 42 moves laterally and outward relative to the support bar 21, and the right link arm 44 simultaneously pulls on the draw rope 60, so that the latter pulls the left link arm 44, so as to pull the left pedal 42 towards the inside with respect to the support bar 21. In this way, the user can simultaneously carry out downward movements and pivoting outward movements to train the leg muscles. We can also train the back muscles,

kidneys and spine.

  In addition, compared with conventional physical training apparatus for walking training which use hydraulic cylinders to achieve a damping effect, the present invention which achieves the desired damping effect by the arrangement of the rope or the traction cable 60, is simpler in its structure. In addition, replacing the pulling rope or cable 60

  is relatively easy and inexpensive.
