  • Patent number: 11071879
    Abstract: The descender comprises a handle and a cam that are movable between a securing position and a sliding position of the rope. The cam defines a first stop and a second pin. The handle has a first pin coming into contact with the first stop to form a first mechanical link and a second stop coming into contact with the second pin. Movement of the handle results in movement of the cam between the securing and sliding positions. In a threshold position of the handle, the first mechanical link is interrupted and the cam returns to the securing position. The second stop is movable with respect to the handle by means of a spring. When movement of the handle takes place, the second pin comes into contact with the second stop before the handle stresses a spring and reaches the threshold position.

  • Patent number: 11052270
    Abstract: A vertical fall arrest safety device travels along a rail of a vertical track and is configured for quick attachment and detachment anywhere along the rail. The device has a mounting body having side rail engagements configured for slidably engaging behind the edges of a rail of the vertical track in use. The engagements are spaced and staggered so as to receive the rail therebetween when the mounting body is at an angle, and then slidably attach to the rail when the mounting body is twisted into alignment with the rail. The device also has a lever pivotally coupled to the mounting body at a fulcrum. As such, when a downward force is applied to a connection point of a distal end of the lever, an opposite distal end of the lever frictionally engages the rail.
