Abstract
The device for climbing a pair of ropes (1) includes releasable upper and lower clasps (4,6) for each rope that clamp in response to a downward force acting thereon but relieve when the downward force is relieved and connecting elements for holding a climber, including a seat (7, 12) or harness (23), Each releasable clasp (4,6) has a housing (21); a yoke (3) in the housing (21) provided with an interior space having beveled inclines widening downward; cotters (10) positioned on opposite sides of the rope (1) in the inner space; rollers (11) arranged movably, but securably, between the cotters (10) and the beveled inclines; a compression spring (20) bearing on an upper end of the yoke (3); and a time servo-component (9) arranged at a lower end of the yoke. The time servo-components (9) act on the yokes so that the clasps (4,6), when relieved, automatically clamp the ropes again after a predetermined time interval.
