DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The amusement ride for children has an open frame and a swinging passenger carriage suspended from a crossbar carried by two trolleys mounted in parallel tracks on the roof of the open frame. The passenger carriage has an upper platform rotatably mounted on a base platform, rotation of the upper platform being controlled manually by the passenger through rotation of a wheel mounted on a column having an end journaled into a bearing mounted in the base platform. A motor is mounted on the roof frame, the shaft of the motor being connected to the crossbar by a crank and connecting rod to control translational movement of the trolleys, causing the passenger carriage to swing forward and backward. The combination of translational movement and swinging movement of the carriage with rotational movement of the upper platform provides a uniquely thrilling sensation for a child seated on the passenger carriage.

[0015] The open frame includes a rectangular base frame, which may have a floor; a rectangular roof frame having two elongated side rails, two end beams, and a center joist extending between the side rails and defining a trolley half and a drive half; and four corner posts joining the base frame and the roof frame. Two parallel channels extend between the end beam and the center joist in the trolley half, defining the parallel tracks. The two trolleys, mounted on wheels, are mounted in the tracks for translational movement, the trolleys supporting the crossbar. A carriage supporting link is rotatably mounted on opposite ends of the crossbar, respectively. The passenger carriage is mounted between the two links so that the carriage swings back and forth with translational movement of the trolleys.

[0016] As shown in FIG. 1A, the amusement ride for children, designated generally as 10 in the drawings, has a rectangular base frame 12. which may include a floor 14. Four posts 16 extend vertically from the corners of the rectangular base frame 12. The posts 16 support a rectangular roof frame 18, which includes two parallel end beams 20 and two parallel side rails 22 extending between the end beams 20. A center joist 24 extends between the side rails 22 parallel to the end beams 20, dividing the roof frame 18 into a trolley half 26 and a drive half 28. A track structure 30 extends between the end beam 20 and the center joist 24 in the trolley half 26 of the roof frame 18, and a motor platform 32 is mounted in the drive half 28 of the roof frame 18.

[0017] A trolley assembly 34 is mounted in the track structure 30 and is constrained to translational movement between the end beam 20 and the center joist 24 above the trolley half 26 of the rectangular roof frame 18. The trolley assembly 34 includes a crossbar 36 extending laterally between and above the sides of the rectangular roof frame 18. A passenger carriage 38 is suspended from the trolley assembly 34 by two elongated links 40, the links 40 being rotatably mounted at opposite ends, respectively, of the crossbar 36 by suitable roller bearing assemblies or the like so that inertia causes the passenger carriage 38 to swing outward and upward when the trolley assembly 34 reaches the respective ends of the track structure 30 and reverses direction, swinging in a pendulum motion as the trolley assembly 34 engages in reciprocating translational movement.

[0018] The trolley assembly 34 is actuated to engage in translational movement by a motor (not shown in FIGS. 1A-1D; see FIG. 2) mounted on the motor platform 32 of the drive half 28 of the roof. The motor may be an electric motor or a gas-powered motor, and may be reversible, although rotation through 360° will drive the trolley assembly 34 to both ends of the track structure 30, so that one cycle will return the trolley assembly 34 to its starting point. The shaft of the motor is rotatably mounted in an opening formed through a support post 42 extending upward near an edge of the motor platform 32. A crank 44 is fixed to the shaft of the motor for rotation therewith. An elongate connecting rod 46 has one end pivotally attached to the crank 44 and the opposite end pivotally attached to the crossbar 36 mounted on the trolley assembly 34.

[0019] As shown in FIG. 1A, when the crank 44 is rotated to the 3:00 o'clock position, or 0° (behind the connecting rod 44 in FIG. 1A), the trolley assembly 34 is drawn in the track structure 30 to the maximum extent of its travel towards the center joist 24. As shown in FIG. 1B, when the crank 44 is rotated to the 6:00 o'clock position, or −90° (extending downward through an open space in the rectangular roof frame 18 adjacent the motor platform 32), the trolley assembly 34 is translated in the track structure to a position approximately midway between the center joist 24 and the end beam 20 in the trolley half 26 of the roof frame 18. As shown in FIG. 1C, when the crank 44 is rotated to the 9:00 o'clock position, or 180°, the trolley assembly 34 is translated in the track structure to the maximum extent of its travel towards the end beam 20 in the trolley half 26 of the roof frame 18. Finally, as shown in FIG. 1D, when the crank 44 is rotated to the 12:00 o'clock position, or +90°, the trolley assembly 34 is translated back to a position approximately midway between the center joist 24 and the end beam 20 in the trolley half 26 of the roof frame 18.

[0020] As shown in FIG. 2, the motor 48 is mounted on the motor platform 32 in the drive half 28 of the roof frame 18. The motor shaft 50 is retained by the support post 42, through which the shaft 50 extends to connect with the crank 44. The trolley assembly 34 includes two trolleys 52, each trolley 52 being supported on wheels 54 or rollers. The track structure 30 includes two parallel U-shaped channels or tracks 56 extending between the center joist 24 and the end beam 20 in the trolley half 26 of the roof frame 18, the trolley wheels 54 being constrained to roll in the tracks 56. The trolleys 52 ae constrained to translate in unison in the tracks 56 by the crossbar 36 extending through the walls of the trolleys 52.

[0021] The passenger carriage 38 is shown in more detail in FIGS. 3A and 3B. The passenger carriage 38 has a circular base platform 58, the links 40 being rigidly attached to diametrically opposite positions near the perimeter of the base platform 58. A circular passenger platform 60 of smaller diameter than the base platform 58 is rotatably mounted above the base platform 58. A steering post or column 62 extends upward from the center of the passenger platform 60. The passenger platform 60 is rigidly attached to the steering post 62 for rotation therewith. The steering post 62 has a lower end extending below the passenger platform 60 that is journaled into a bearing 64 seated in the center of the base platform 58 to permit rotation of the steering post 62 and the attached passenger platform 60 relative to the base platform 58. In addition, there may be at least one ball bearing 66, roller bearing, or other suitable bearing disposed between the passenger platform 60 and the base platform 58 to reduce friction. The at least one ball bearing 66 may be incorporated into a Lazy Susan bearing having an upper bearing plate 68 attached to the passenger platform 60 and a lower bearing plate 70 attached to the base platform 58. The steering post 62 has an upper end having a wheel 72 attached thereto, which the child or the ride operator may turn to rotate the passenger platform 60 while the passenger carriage 38 is swinging during translational movement of the carriage 38 for an added thrill. One or more seats 74 may be mounted on the passenger platform 60 for the comfort of the children, the seats having a suitable safety belt, strap, or harness attached thereto. As shown in FIGS. 1A-1D, the passenger carriage 38 may also include an outer annular safety handrail 76 attached to the links 40 and posts 77 extending from the base platform 58, and an inner annular safety rail 78 attached to posts 80 mounted on the passenger platform 60.

[0022] Thus, the amusement ride operator may activate the motor 48 in forward and reverse directions to induce swinging motion of the passenger carriage 38 while simultaneously a rider may manually activate rotation of the passenger platform 60 to produce a combination of swinging and rotating sensations in the passenger(s).
