  • Patent number: 11130665
    Abstract: A mobile recreational lift system, comprising a first lift vehicle and a second lift vehicle, each lift vehicle having an observation platform for carrying passengers, and an articulating lift mechanism for elevating the observation platform above a ground surface. The lift vehicles are positioned at an observation site in a paired configuration, allowing the observation platforms of both vehicles to be elevated simultaneously while retaining the ability to be independently controlled. The lift mechanisms are also adapted to move the observation platforms laterally, allowing the observation platforms to be placed in close proximity to allow the passengers to interact. If one of the lift vehicles malfunctions, the other lift vehicle may immediately position its observation platform to aid the passengers of the malfunctioning vehicle. Cameras mounted on each observation platform are adapted to capture images of the other observation platform and the passengers therein, from a variety of perspectives.

  • 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.
