Foot, Hand, Or Seat Operated Patents (Class 472/108)
  • Publication number: 20140309047
    Abstract: In one example, a teeter totter is provided that includes four support arms spaced apart at substantially equal angular intervals, with a seat being attached to each of the support arms. A hub of the teeter totter includes top and bottom plates which cooperate to at least partly define four sockets, and each of the sockets receives an end of a corresponding support arm. A plastic receiver is connected to the hub, and a plastic pivot is rotatably engaged with the receiver such that the pivot and the receiver cooperate to enable simultaneous movement of the seats in three dimensions. Finally, a base is provided that supports the pivot.

  • Patent number: 7717799
    Abstract: An improved teeter-totter has a pair of seats mounted at opposite ends of a longitudinal seat support member. The seat support member is suspended from overhead pivots by a pair of linkage arms to provide riders with a motion that combines the up-and-down arcuate motion of a conventional teeter-totter with a back-and-forth gliding motion, thus creating a more stable and balancing effect allowing users of different weights, to use the teeter-totter without other counter balance features.

  • Publication number: 20080300063
    Abstract: Playground equipment may include a seesaw. The seesaw may include a first seat and a second seat facing the first seat. The playground equipment may include one or more additional seats that may face away from the first and second seats and which may be disposed at least proximate a pivot point of the seesaw. The playground equipment may be sized and configured to rock back and forth, for example, in a direction different from the direction that the seesaw moves.

  • Patent number: 6929551
    Abstract: An amusement swing apparatus for children and adults alike and more particularly, a horizontal rotating manually operated swing. It can be conceptualized as two seesaws lapped in the middle at right angles, but instead of the riders going up and down, they remain in a horizontal plane and rotates about the centre point. Where these beams cross at the middle, they are supported on a housing that carries two bearings, one on top of the housing and one at the bottom. This housing is fitted to a vertical shaft that passes through the centre of the lapped beams and allows the housing with the lapped beams to rotate freely around it. The shaft is firmly fixed to the ground or floor surface. Four or six legs, attached to a flange welded to the shaft add support to the structure. These legs spread out evenly around the flange and are fixed to the ground or floor surface. The four outer ends of the beams have seats for persons to sit on.

  • Patent number: 6899631
    Abstract: A seesaw having an elongated planar member assembly, an axle assembly, and a ratchet-and-pawl assembly. The planar member assembly includes an elongated planar member. The axle assembly includes an axle member, an elongated radial extension, and a pair of wheels. The extension member extends radially between, and is coupled to, the axle member and the planar member. The pair of wheels is coupled to the axle member with one wheel disposed on each side of the planar member. The ratchet-and-pawl assembly includes a toothed gear, which is coupled to the axle member, and a pair of pawl assemblies. Each pawl assembly has a pawl member coupled to the planar member and structured to engage the toothed gear.

  • Patent number: 6722996
    Abstract: A moving 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, a user support mechanism, and a user engagement mechanism. The user support mechanism pivotally mounts to the frame structure, while the user engagement mechanism pivotally mounts to the user support mechanism. The user engagement mechanism may have engagement members for engaging said frame structure. 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 mechanism 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 mechanism backward and forward may produces different seat movement, including rotation about the base of the frame structure.

    Abstract: A pivoting 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 backward and forward, not by pushing against the ground with the feet of the users. The apparatus may be configured so that rocking the user engagement means backward and forward may produce different seat movement. The apparatus may also take the form of a single user see-saw and an exercise machine, with an optional weight support member for weighing down one side.

  • Patent number: 5885163
    Abstract: A rotating riding toy for children has adjustability in the linkage which causes the riding toy to rotate. It has been found that such adjustability can affect the ease of pumping or driving the riding toy rotationally as well as the rotational speed obtained. In addition, the seats are positionally adjustable to accommodate smaller and larger children. Quick release pins are envisioned for removing stabilizing legs from a base member to afford breakdown of the mechanism and portability.

  • Patent number: 5512018
    Abstract: A wheeled seesaw amusement device having a tubular frame with telescopic sections capable of having vary length. The tubular sections interconnect at opposite ends to form contact sections with the ground. The frame is supported by an axle mounting a pair of wheels and by strut members pivotally carried by the axle. The position of the strut members relative to the frame can be varied to alter the vertical height of the frame.

  • Patent number: 5269735
    Abstract: A floor-borne fitness apparatus with variable stepping heights includes an upper stepping floorboard and substructural parts which can increase the height and/or the inclination of the floorboard. The apparatus has at least one attachment element which can cooperate with an exercise expander band. The floorboard cooperates with the substructural parts in such a way as to form a positively engaging support unit. Such construction prevents the unintended tilting of the apparatus.
