Patent number: 8371951Abstract: A swing ride for providing lateral movement to a plurality of passenger vehicles. The ride includes a center hub rotating about its axis. The ride includes, for each of the passenger vehicles, a vehicle support assembly attached to rotate with the hub. The vehicle support assembly includes a flexible support member attached at a first end to the hub and at a second end to one of the vehicles. The vehicle support assembly includes a fulcrum assembly defining a fulcrum or pivot point for the support member between the first and second ends such that the member has a flexible and variable-length flexible arm attached to the vehicle. The fulcrum assembly is selectively positionable to move the fulcrum point in response to user input at the vehicle such that the passenger interactively moves the fulcrum point and thus moves the vehicle laterally inward and outward relative to the spinning hub.Type: GrantFiled: December 13, 2010Date of Patent: February 12, 2013Assignee: Disney Enterprises, Inc.Inventors: Edward A.

Patent number: 8371227Abstract: A ride system with crossing ride paths. A first omnimover assembly is provided that includes a continuous vehicle chain movable along a first ride path and includes vehicles vertically supported above the track at a first height. A second omnimover assembly is provided with a continuous vehicle chain movable along a second ride path that differs from the first ride path and crosses over the first ride path when viewed in plan view. The second omnimover assembly includes vehicles vertically supported below the upper vehicle track at a second height, which may be the same as the first height such that passengers perceive a risk of a collision at the path intersections. The upper track is at a higher elevation than the lower track such that cross overs occur without interference. A synchronization mechanism is provided that synchronizes the movement of the upper and lower vehicle chains.Type: GrantFiled: July 14, 2011Date of Patent: February 12, 2013Assignee: Disney Enterprises, Inc.Inventors: Edward A.

Publication number: 20130025491Abstract: A floating omnimover ride with high capacity throughput and enhanced control over speeds of passenger boats. The ride includes a water containment structure with spaced apart sidewalls defining an elongated guide channel that defines a loop-shaped ride path or circuit. The ride includes a volume of liquid contained in the guide channel to a desired depth. The ride also includes a chain of passenger boats floating in the liquid contained in the guide channel. Each of the boats is linked to the two adjacent boats with a connecting link such that the chain of boats is a continuous loop. The chain of boats has a length that is approximately equal to a length of the ride path, and during operation of the ride, the boats in the chain are moved along the loop-shaped ride path at a predefined rate by a pump station moving the liquid in the guide channel.Type: ApplicationFiled: July 29, 2011Publication date: January 31, 2013Applicant: DISNEY ENTERPRISES, INC.Inventors: David W.

Patent number: 8342976Abstract: A rotating hub ride configured to position passenger vehicles at different vehicle radii relative to the hub's axis of rotation. The ride includes curved support arms extending outward from the hub, with a first end coupled to the hub at a lower height than a second end of the arm. A vehicle is attached, via a mounting assembly, to each curved support arm to slide radially inward and outward on the arm in response to forces applied to the vehicle due to rotation of the hub, e.g., at two or more hub rotation rates. The arm or track defines a travel path for radial movement of the vehicle. When hub rotation is halted, the vehicle slides inward on the track to a load position corresponding to a minimum vehicle radius. At increasing hub speeds, the vehicle slides outward to position the vehicle in any of a number of vehicle radii.Type: GrantFiled: October 6, 2010Date of Patent: January 1, 2013Assignee: Disney Enterprises, Inc.Inventors: David W.

Patent number: 8337317Abstract: A Ferris wheel-type ride. A lever arm is mounted to the wheel rim to freely pivot between front and rear stops. Passenger gondolas, pivotally attached to the lever arms, travel through four zones experiencing differing ride dynamics. In the first zone, the lever arm abuts the front stop while, in the second, the lever arm is spaced apart from the stops and the lever arm is supported from above by the wheel via the lever arm causing the gondola to be vertically lifted and to rotate slower than the hub rotation rate. In the third zone, the lever arm abuts the rear stop and, in the fourth zone, the lever arm is spaced apart from the stops and is supported from below by the wheel as it falls toward the front stop at a rate greater than the hub rotation rate.Type: GrantFiled: September 16, 2010Date of Patent: December 25, 2012Assignee: Disney Enterprises, Inc.Inventors: David W.

Patent number: 8328367Abstract: A projection system for projecting light such as images or content upon a liquid surface such as a lake or pool surface. The system includes an agitation assembly selectively operable to agitate a portion of the upper surface of liquid to form a projection screen. The system includes a projector assembly projecting or focusing light onto the projection screen on the upper surface of the liquid. The liquid is translucent to light, but the projection screen on the upper surface reflects a portion of the projected light due to the agitation. The agitation assembly may include an aeration system with a distribution manifold and is positioned below the liquid surface and has outlets discharging gas into the liquid such that air bubbles for the screen. The manifold outlets may be provided at two or more depths, whereby two or more portions of the projection screen are generated at differing times.Type: GrantFiled: May 6, 2011Date of Patent: December 11, 2012Assignee: Disney Enterprises, Inc.Inventors: Edward A.

Patent number: 8303426Abstract: A round ride with passenger-initiated motion profiles controlling vertical vehicle movements. The ride includes a drive assembly with a rotating hub that includes support arms extending outward from the structure supporting passenger vehicles. Each of the vehicles includes a triggering device capable of generating either an onboard or offboard discrete signal when operated by a passenger causing a controller to select a motion profile from a number of stored profiles that each defines an actuator motion profile (or angular movement of a support arm about its pivotal mounting point to the rotatable central hub). The motion profiles define different angular rotations for a support arm to cause a vehicle to jump to differing heights, and the profile may be chosen by the controller based on vehicle height and position along the circular path and other environmental inputs such as a game state for the vehicle or a show/ride status.Type: GrantFiled: August 11, 2010Date of Patent: November 6, 2012Assignee: Disney Enterprises, Inc.Inventors: David W.
