First Claim
Patent Images
1. A safety device on a rope, comprising:
- a first flange-plate and a movable second flange-plate delineating a transverse space in which a roller is arranged fitted on a first spindle integral to the first flange-plate,articulation means of the second flange-plate comprising a second spindle allowing a swivelling movement between a closed position clamping the rope in captive manner in the transverse space, and an open position for fitting the rope on the roller,wherein;
the first flange-plate presents clearance by positioning of the second spindle in an aperture of the first flange-plate, the external diameter of the second spindle being smaller than that of the aperture to define said clearance,and the movable second flange-plate is equipped;
with a securing notch operating in conjunction with the first spindle to block the device in the closed position when the roller is under load,and with a latch actuated by control means to perform unlatching of the latter enabling opening of the second flange-plate when the device is no longer under load.
