Patent ID: 7073628

Claim:
A climbing device for a climber climbing or descending at least one weight-bearing element ( 1 ), said device comprising releasable clasps ( 4 , 6 ) each comprising means for clamping said at least one weight-bearing element ( 1 ) in response to a downward force acting thereon and means for releasing said at least one weight-bearing element ( 1 ) when said downward force is relieved; and connecting means ( 7 , 8 ; 17 ) attached to said clasps ( 4 , 6 ) for holding and supporting said climber so that said climber is able to apply and relieve said downward force; wherein each of said clasps comprises a resilient time servo-component ( 9 ) acting on said means for clamping said at least one weight-bearing element to again clamp said at least one weight-bearing element ( 1 ) when a predetermined time interval starting with relief of said downward pressure expires, wherein said resilient time servo-component is an elastic rubber member, a hydraulic spring or a pneumatic spring and said means for clamping said at least one weight-bearing element comprising inclined bevels pivotably mounted in said housing and forming an interior space widening downward; cotters positioned on opposite sides of said at least one weight-bearing element in between said inclined bevels; rollers arranged movably, but securably, between said cotters and said inclined bevels in said interior space; wherein said inclined bevels are connected to said resilient time servo-component so that said inclined bevels respond to said time servo-component when said time servo-component acts on said means for clamping.
