Apparatus for learning to ski

Claim 2

Apparatus for learning to ski, characterized by the fact that it comprises harness means (2) which permit supporting the skier (1) off balance just before his fall, said harness means being connected to a movable carriage (6) by means of retention straps (13a, 13b), said carriage (6) being movable on a roller track which serves as a rail (8), in which the carriage (6) is mounted on rollers, and comprises brake means (10a, 10b), and in which, in order to adjust the application and/or release of the brake means (10a, 10b) as a function of the weight of the skier, cross bars (3 and 4) having several holes (21) are disposed along the longitudinal axis, and in which oppositely acting springs (R 1 , R 2 and R 3 , R 4 ) and an actuating lever (14), having notches (16, 17) which cooperate with a pawl (18), permit exact adjustment of the moment at which the retention straps (13a, 13b) will act on the cross bars (3 and 4) so as to apply the brake means (10a, 10 b) on a vertical wall of said rail (18).

Claim 3

Apparatus for learning to ski, characterized by the fact that it comprises harness means (2) which permit supporting the skier (1) off balance just before his fall, said harness means being connected to a movable carriage (6) by means of retention straps (13a, 13b), said carriage (6) being movable on a roller track which serves as a rail (8), in which the carriage (6) is mounted on rollers, and comprises brake means (10a, 10b), and in which the retention straps (13a, 13b) are secured to the ends of two cross bars (3 and 4) which at their other ends (12a, 12b) carry brake shoes (10a, 10b), the assembly of cross bars (3, 4) and shoes (10a, 10b) being mounted on the chassis (5) of the movable carriage (6), pivotably about axles (25a, 25b), and in which a lever (14) mounted pivotally on one said cross bar (4) by its axis (15) has notches (16 and 17) which register with a pawl (18), which is at this level on the other cross bar (3); a spring (R 4 ) acting to maintain the lever (14) raised in a position in which the pawl (18) is engaged in one or the other of the notches (16 or 17).

Claim 4

Apparatus for learning to ski, characterized by the fact that it comprises harness means (2) which permit supporting the skier (1) off balance just before his fall, said harness means being connected to a movable carriage (6) by means of retention straps (13a, 13b), said carriage (6) being movable on a roller track which serves as a rail (8), in which the carriage (6) is mounted on rollers, and comprises brake means (10a, 10b), and in which the retention straps (13a, 13b) are secured to the ends of two cross bars (3 and 4) which at their other ends (12a, 12b) carry brake shoes (10a, 10b), the assembly of cross bars (3, 4) and shoes (10a, 10b) being mounted on the chassis (5) of the movable carriage (6), pivotably about axles (25a, 25b), and in which a lever (14) mounted pivotally on one said cross bar (4) by its axis (15) has notches (16 and 17) which register with a pawl (18), which is at this level on the other cross bar (3); a spring (R 4 ) acting to maintain the lever (14) raised in a position in which the pawl (18) is engaged in one or the other of the notches (16 or 17).

Claim 5

Apparatus for learning to ski according to claim 1, characterized by the fact that one spring (R 1 ) tends to move the brake means (10a, 10b) relative to said vertical wall of the rail (8), while two oppositely acting springs (R 2 and R 3 ) tend to move the brake means in the opposite direction.

Claim 6

Apparatus for learning to ski according to claim 2, characterized by the fact that after applying the brake means, the skier, to start again, can pull on a cable (23) by means of a handle (24), this cable (23) lowering the control lever (14) which frees the pawl (18) from its notch (16), the brake means releasing under the action of lever (14) which resets the cross bars (3 and 4).
