  • Patent number: 9415317
    Abstract: A teeter-totter device is provided that includes an elongated beam with slidable weights to balance the load of one or more users on the beam. The device includes a base that rotatably supports the beam and acts as a fulcrum point for the beam to rotate. A seat is disposed on each end of the beam, and one or more channels extend along the length of the beam. Slidable weights are disposed within the channels and are movable along the beam and within the one or more channels, whereby weight along the beam is used to account for a single user, or two users of different weights using the device. The slidable weights are securable into a static position along the length of the channel, thereby adding weight to one side of the beam or the other based on the load in each seat.

  • Patent number: 8100776
    Abstract: A safer, more user-friendly spring-balance single-rider teeter-totter includes manual adjustments for both the vertical position of the spring, which adjusts the rest height of the seat, and the horizontal position of the spring from the pivot, which adjusts the counterbalance resistance. A safety cover may be provided for the spring or other counterbalance mechanism.

  • Patent number: 7682258
    Abstract: An apparatus includes a support member, a moveable member supported by the support member, a user support mechanically associated with the moveable member, and a sound producing mechanism that produces sound as a result of movement of the moveable member between a first position and a second position caused by the user's application of force to the urge the moveable member between the first position and second position. The applications include a play apparatus, wherein the user interacts with the moveable member with the result that the moveable member changes position and a selected sound is thereby produced.

  • Patent number: 7413516
    Abstract: A teeter-totter is constructed with a pair of seats mounted at opposite ends of a rocker beam. The seats, when aligned horizontally, are below the pivot point so as to provide a pendular component of motion. The pivot is supported on an overhead framework and the rocker beam is suspended below the pivot to eliminate the pinch points found in conventional teeter-totter designs. A counterbalance mechanism may be incorporated so that users of different weights remain in balance while operating the teeter-totter.

  • Patent number: 6988951
    Abstract: A system and method are disclosed for providing movement to a person having a person center of gravity and a person moment. The system includes a receptacle configured to allow the person to adjust the person center of gravity, a counterweight for counterbalancing the person moment, a beam connecting the receptacle and the counterweight, a base for supporting the beam, a base joint connecting the base and the beam, configured to allow the beam to rotate with respect to the base joint; wherein an adjustment in the person center of gravity provides rotation of the beam.

  • Patent number: 6872145
    Abstract: A solo-operable seesaw includes a base member having oppositely spaced side sections for engaging a ground surface and further includes a plurality of elongated braces having opposed end portions connected thereto. The seesaw further includes an elongated plank having a first end portion engaged with the base member and selectively pivotable thereabout. The plank further has an oppositely spaced second end portion defining a seat and includes a plurality of elongated handlebars extending outwardly from the plank. The seesaw further includes a mechanism for pivotally lifting the plank upwardly along a predetermined arcuate path after the second end portion of the plank is moved to select lowered positions. The lifting mechanism includes a spring-loaded hydraulic air piston having opposed end portions and a plurality of brackets connected thereto. The lifting mechanism-further includes an elongated swivel pin transversely passing through the plank for connecting same to the base member.

  • Publication number: 20030022723
    Abstract: A turning uplift apparatus is provided which enables the user to utilize the device as a piece of playground or backyard play equipment commonly known as a see-saw. The apparatus includes a frame structure means, a user support means, and a user engagement means. The user support means pivotally mounts to the frame structure means, while the user engagement means pivotally mounts to the user support means. The apparatus is different from the more conventional see-saw apparatuses in that the upward and downward pivoting motion of the user is produced by rocking the user engagement means forward and backward, not by pushing against the ground with the feet of the user. The apparatus may be configured so that rocking the user engagement means backward and forward may produces different seat movement, including rotation about the base of the frame structure means.
