Seesaw Track Patents (Class 104/79)
  • Patent number: 6862997
    Abstract: This invention relates to an amusement device and method for using an amusement device. The amusement device comprises a guideway being pivotable around a swivel axis, the axis being transverse to the guideway, and a bearing frame carrying, at a distance from the ground, the guideway wherein a passenger carrier is mounted to said guideway and in that the passenger carrier is movable along said guideway. Preferably the guideway is rotatable around an essentially vertical rotation axis.

  • Patent number: 5638755
    Abstract: A trolley includes a track having first and second ends. A pivot is located between the first and second ends of the track so that movement of the first end of the track causes opposite movement of the second end of the track. A counterweight is located near the first end of the track so as to apply downward force. A trolley is movable along a portion of the track located between the pivot and the second end of the track. The trolley has a handle or carriage for a user. The combined weight of the user and the trolley overcomes the counterweight so as to move the second end of the track downward causing the trolley to move along the track toward the second end of the track. The counterforce is sufficient to move the second end of the track upward and to return the trolley to the starting position when the weight of the user is released from the trolley. The trolley moves between a first platform located near the starting position and a second platform lower than the first platform.

  • Patent number: 5174569
    Abstract: A route diverter for selecting a first or a second track route for a slot track vehicle to follow is disclosed. The diverter is engageable with track portions of the first and second routes and comprises a platform and means for supporting the platform for see-saw movement between first and second positions in which the first and second routes are respectively selected, the platform being movable in response to movement of a slot track vehicle past the diverter to change the route selected.

  • Patent number: 4973042
    Abstract: An amusement ride is illustrated having an annular passenger housing (A,A',A",A'") which surrounds a central tower (B, B', B") and is driven relative to the tower in vertical, tilting or wobbling, and/or rotary motion by a drive arrangement (12,16,18,42,44,50). Passsenger containment units (30,64,64') carried on tracks (32) or carriage rings (60,60') are guided in a prescribed path, depending on the configuration of the annular housing, in response to the resultant motion of the annular housing. A simulated effect of annular housing (A') riding atop a geyser (F) may be provided to enhance the ride.

  • Patent number: 4938148
    Abstract: An adjustable seesaw ski-track includes a stationary central part and separate wing sections pivotally connected to opposite sides of the central part, each wing section including a horizontal platform section and a plurality of pivotally connected wing sections extending between the platform and the central part. A coupling rod connects the two wing sections together, and a hydraulic cylinder assembly is connected to one of the wing sections so as to raise and lower its platform section relative to the central part, thus pivoting the wing section upwardly and downwardly relative to the central part, the coupling rod causing the other wing section to respectively pivot downwardly and upwardly relative to the central part.

  • Patent number: 4919052
    Abstract: A track apparatus for a toy racing car includes a car-entry track portion, a car-exit track portion, and a pivotal arm pivotally mounted between the two track portions to carry a car from one portion to the other. The pivotal arm has a stand connected to a distal end thereof which has a retractable stop. When a car travelling with sufficient momentum hits the stop, the pivotal arm is caused to pivot from one position to another, whereby the car is delivered from the car-entry track portion to the car-exit track portion. Upon reaching the second position, the stop is automatically retracted to release the car.

  • Patent number: 4249733
    Abstract: A racing toy including a pair of side-by-side main tracks defining down-hill paths for a pair of gravity operated vehicles. The opposite ends of each track are spaced from each other and a pair of pivotal ramps are disposed in such space so as to in effect interconnect such ends. Each ramp has a vehicle receiving portion at one end and an angularly disposed launching portion and is pivotally supported adjacent the initial elevated end of its respective main track. The ramp may be alternatively moved from a lowermost vehicle receiving position to an elevated vehicle launching position so as to in effect form continuous closed loop trackways around which the vehicles may cycle a desired number of turns. The means for elevating the ramps include outwardly projecting handles for the participants of the toy to appropriately manipulate the respective vehicles across the space defined by the track ends.
