struts 9, 10 through tunnels 14 of the body of the stiffener 16, 22 are connected with a ratchet mechanism at the level of the knee joint. On the waist belt 1, the lower ends of the support legs of the frame of the easel backpack with the load can be attached to the hooks 2. The articulation of the hinge is provided by a ratchet mechanism, in the knee joint, which is locked by the dog 11, which is one of the ends of the struts 9, 10, which are moved under the action of the body and the gear to the gearing side. At the same time, a complete lack of unity of these hinged connections is provided only in the range of the backbone / bn r stdk / b / ... b 10 in a line, but only in case of the movement of the mass / lai and. the load and down load racks are 9.10 vt ;; the even distribution of these masses on the supporting platforms, Moreover, m1sh1 {s .. notes from the effort to support; ny: mass and load; grow up with. v loaded with only a few muscle muscles that hold the body from tipping over. rtr is the 2U latrrma and hinge 19.

The work of the device in dynamics is characterized by the fact that it takes 6 mass. Weight of one piece on one of the Horv Libra socks of both vogs, frees up the 9V10 racks, as a result of which we support: masses; move the parts of the support platform and the racks to the torsion, and the dog 11 moves away from the gear segment 12, which leads to the release of ratchet engagement in the hinge located on the axis 13. Free displacement of the movable racks 9, 10 relative to the stationary body 15, swivel joints 19, 21 contribute. As a result of the ratchet mechanism being released, the leg becomes fully mobile in the knee joint and can be advanced or the knee bends naturally when squats. When the leg is advanced, a step is taken, the center of gravity is transferred to the forward leg that is extended forward. In this case, the body mass moves down together with the support legs 5, 6 of this leg until the dog 1.1 abuts against the wheel segment 12, i.e. prior to gear ratchet engagement. If the movement is on a horizontal surface, then the forward leg at the moment of support, practically does not bend at the knee joint, mainly the hip and ankle joints work. In this case, a significant portion of the time, the mobility of the knee joint may be blocked. If the movement is carried out over rough terrain, for example, by stairs, then at the moment the center of gravity is transferred to the movable part of the support platform, the knee joint is in a displaced state, i.e. the leg is bent. At the same time, fixing the ratchet mechanism does not lead to complete immobility of the knee joint, because it is possible to completely straighten the legs due to the slipping of the teeth of segment 12 relative to the dog 11. Naturally, the reverse movement in the hinges is blocked due to the inclination of the teeth. The effect of saving muscle effort is provided due to the possible shift of the load on the leg muscles towards the static, when at any stage of movement (bending, unbending) of the leg, the mode of its active rest is possible, when it is possible to relax the muscles that hold body weight. Actually, this effect is also present when lifting weights from the full squat position, because rest at any stage of the movement is possible. Similarly, the effect of relieving muscle load, although to a lesser extent, is present in other modes of movement: walking, running, and the like. Additional safety against injuries in the event of a fall is achieved due to the presence of a protective cap 18, strips 16, 22 and additional racks 6, 9. In order to increase the reliability of operation, in case of jamming or breakage of the ratchet mechanism, an unlocking mechanism is used. To do this, the toe under the heel 26 of the support leg is retracted by the toe of the non-support leg. Previously, it is necessary to unload the supporting platform of the supporting leg. For this purpose, the center of gravity should be transferred to the toe. As a result, the sole of the shoe is removed from the support platform and the stand 26 moves under the heel. In this case, the rods 25 are recessed in the recess 24, compressing the spring 27. The support is fixed by transferring gravity to the supporting leg and the presence of a locking mechanism. If it becomes necessary to turn on the ratchet mechanisms of the leg, then more

vigorous inclination of the body relative to the toe of the supporting leg. In this case, the heel rises and releases the stand 26, which, under the action of the force of the springs 27, moves away from the support platform. Availability

stiffness bars 16.22 allows you to reduce, if necessary, the number of supporting belts 17 to one per rack, because reliable fixation of the limbs when walking is provided.
