  • Patent number: 9707976
    Abstract: A device that is movable along a track defined by a cable has a main frame including a pair of side walls and a transverse connector by which the side walls are joined together. A pair of pulleys is disposed between the side walls, with the pulleys being engagable with a cable and rotatable for movement of the device along the cable. A fitting by which handles are removably attachable to the main frame is secured between the side walls, and aligned receptacles in the side walls provide for reception of hardware to preclude disengagement of the cable from the pulleys during use.

  • Patent number: 9669319
    Abstract: A cable in suspension (clear span) supports a trolley. At the upper end, a launch block fixed to the cable registers the trolley in all directions, including a safety release link holding the trolley near the launch block. After release and descent with a rider, the trolley strikes an attenuator of distributed springs and spacers. The spring stack absorbs momentum from the trolley, but a leash limits recoil “bounce” after reversing the trolley. A second, recoil, leash resists recoil by capturing a subset of the springs between respective ends of itself and the first leash. The doubly leashed trolley will oscillate to a stop in an equilibrium position.

  • Patent number: 9393496
    Abstract: The lever, wheel and axle, pulley, wedge, screw, and inclined plane are the six Simple Machines of the Classical era. Over 2000 years ago a man from Syracuse used them to create a way to move water against the pull of gravity. The Archimedes' screw is still a standard for simple efficiency. In homage to those early machines and the dreamers who built them, the Human Flying Apparatus provides a carriage, wheels and an axle, a harness, and a braking and steering_system and, in specific embodiments, thrusters, all suspended from a single rail, which allows a human being to soar in simulated flight that is_safe, sustained, and suitable for all skill levels. “For once you have tasted flight, you will walk the Earth with your eyes turned skyward, for there you have been, and there you long to return.

  • Patent number: 9242659
    Abstract: A high-speed magnetic trolley that utilizes an eddy current brake that may reduce the speed of a person in a harness traveling on a relatively steep zip line cable, making it possible to reach a landing brake at a reasonable speed and becomes easy to adjust an amount of braking force needed to reach a desired speed by taking off or adding more magnets without throwing one or more aluminum wheels out of balance. The high-speed magnetic trolley produce an eddy current that generates an opposing magnetic field, which then resists rotation of one or more aluminum wheels providing braking force.

  • Publication number: 20140311376
    Abstract: An improved zip line trolley allowing a rider control of his or her speed while traversing along a suspended cable. The trolley comprises front and back wheels conjoined via left and right trolley plates and a handle bar. Front and back hand brake levers are mounted onto the handle bar. When front and back hand brake levers are squeezed by the rider, they create a constricting force which applies friction to the suspended cable via brake pads. This frictional force slows the rider's speed to his or her desired rate and brings the rider to a safe stop at a precise location along the suspended cable. The rider is able to quickly and easily remove the trolley from the suspended cable and transport it to another.

  • Patent number: 8807292
    Abstract: Improvements in a braking system for a zip line are presented. Braking occurs when a zip line rider makes contact with a braking carriage that slides along the zip line. The braking carriage pulls on a rope. The rope pulls on a length of chain in a chain reservoir to slide and lift the claim through the chain reservoir. The chain reservoir is an elongated tube that is mounted at an angle. As the zip liner moves further into the landing platform they lift a continuing greater amount of chain from the chain reservoir. The angle of the chain reservoir, coefficient of friction between the chain and the chain reservoir affects the pull-back. After the zip liner comes to a complete stop they remove the carriage from the zip line and gravity returns the brake mechanism. Minimum pull-back makes removal of the cable trolley easier.

  • Publication number: 20110303115
    Abstract: A system comprising a cable held in suspension and a trolley traveling along the cable relies on a brake to control velocity and net downhill acceleration of the trolley. The trolley may include a brake pad positioned to contact the cable. At the downhill end of the ride, the lever actuating the brake is caught and lifted by a capture ring, thus relieving the braking load on the trolley. Also, the trolley engages a comparatively modest, second resistance mechanism, such as, for example, a system of springs, that gradually increases in resistance with distance of motion of the trolley thereagainst, bringing the trolley to a gradual halt.

  • Publication number: 20110283913
    Abstract: A novel zip-line construction capable of three-dimensional movement is disclosed. The zip-line construction generally comprises a single or dual cable member having two ends, a trolley assembly having the ability to traverse a desired distance along the cable member and at least one device capable of attaching the cable member to a separate fixed body. The zip-line of the invention expands movement of the traditional zip-line from two-dimensional movement to three-dimensional movement, thereby advantageously providing a longer and more thrilling ride experience.

    Abstract: A transfer device has a roof fixture adapted to be secured to a roof and protrude upwardly. A first support cable is connected to the roof fixture at a first support cable upper end and a second support cable connected to the roof fixture at a second support cable upper end. A control line has a first segment at a first end and a second segment at a second end. A first carrier is suspended from the first support cable via a first trolley, and the first carrier is connected to the first segment of the control line. The first carrier comprises a tray structure having a first cavity for receiving articles. The first carrier has a tray which is pivotally connected to the first carrier to allow pivotal dumping of the contents from the first tray.

  • Patent number: 7966940
    Abstract: A system comprising a cable held in suspension and a trolley traveling along the cable relies on a brake to control velocity and limit net downhill acceleration of the trolley. The trolley may include a brake pad positioned to contact the cable. At the downhill end of the ride, the lever actuating the brake is caught and lifted by a capture ring, thus relieving the braking load on the trolley. Also, the trolley engages a comparatively modest, second resistance mechanism, such as, for example, a system of springs, that gradually increases in resistance with distance of motion of the trolley thereagainst, bringing the trolley to a gradual halt at a rate to improve comfort of a rider and reduce acceleration forces (loads) on the trolley.

  • Patent number: 7966941
    Abstract: An improved zip line trolley allowing a rider control of his or her speed while traversing along a suspended cable (8) as seen in FIGS. 1A and 1B. The trolley comprises front and rear pulleys (44F) and (44R) conjoined via pulley housing (16) with left and right horizontal handles (10L) and (10R) attached to vertical shaft (12). Front and rear hand brake levers (20F) and (20R) are mounted onto left and right horizontal handles (10L) and (10R). When front and rear hand brake levers (20F) and (20R) are squeezed by the rider, they create a constricting force on front left and right calipers (32FL) and (32FR) along with rear left and right calipers (32RL) and (32RR) of FIGS. 2A and 3A. Thus, friction is applied to front and rear pulleys (44F) and (44R) via front left and right brake pads (34FL) and (34FR) along with rear left and right brake pads (34RL) and (34RR).
