The rope (4) with a hook (18) is wound on the pulley (3) which is fastened on the axis (2). The axis (2) is displaced outside the contour of the pulley (3) groove and is attached to the end of the L-shaped housing (1). The other end of the L-shaped housing (1) is fixed to the belt (10). The pulley (3) is connected to the lever (12) on which end an axis (14) is fixed with a handle (15) rotating on it. The L-shaped housing (1) is attached to the crank (17). The pulley (3) is fixed to the shaft (7) parallel to the axis of rotation of the pulley (3) on which the shackle (8) is thrown on. The shackle (8) is connected by the rope (9) with a annular belt (10) for a leg. The shaft (7) on the hinge (13) with an axis perpendicular to the shaft (7) with the axis (14) and the handle (15) at the end the lever (12) is attached. The end of the L-shaped housing (1) via the rope (21) the second annular belt (22) is attached for the second leg.EFFECT: device is folded and fits in the pocket; the lifting and descent is carried out by one arm and one leg.6 cl, 5 dwg |
