Abstract: A teeter totter apparatus comprises a base portion, a caster assembly including a caster base portion having a plurality of caster base holes for fixing the caster base portion to the base portion, and a caster yoke portion rotationally coupled with the caster base portion allowing rotation of the caster yolk portion about a first axis. A beam portion coupled with the caster yolk portion includes at least one seating portion and is capable of being fixed to the caster yolk portion while allowing the beam portion to rotate about a second axis. In another aspect, a teeter totter apparatus includes a seating portion and opposing seat adjustment portion that sandwich the beam and allow the seat portion to be adjusted in position along the beam. In another aspect, a lazy Susan rotational bearing coupled between the base and yolk portions provides the rotational capabilities for the apparatus.

Abstract: A motion apparatus for use in combination with a standard infant carrier, such as a car seat. The motion apparatus comprises a support structure and a frame for receiving the transportable base of an infant car seat, and a drive assembly, which, when activated causes motion of the infant carrier. Methods and devices of the invention are useful to soothe an infant.

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.

Abstract: An amusement apparatus that includes a base, an arm, a seat biasing device and a arm biasing device. The base is configured for placement on to a generally horizontal surface. The arm has a distal end and a proximal end. The proximal end of the arm is rotatably and pivotally coupled to the base. The distal end of the arm includes a seat. The seat biasing device is coupled to the seat and configured to repeatedly and resiliently contact the surface. The arm biasing device is coupled to a pivot member and the proximal end of the arm. The arm biasing device is configured to upwardly bias the seat of the arm.

Abstract: A rocking and spray system for promoting paired outdoor activity by and cooling for children. The rocking and spray system includes a substantially arcuate hollow cradle portion designed for resting on a support surface such as the ground and for rocking along an arcuate perimeter surface; a pair of seat portions coupled to the cradle portion and positioned adjacent to an associated one of a pair of ends of the cradle portion and designed for supporting a posterior of a human; and a water receiving portion designed for coupling to a conventional garden hose to facilitate routing of water to spray a user.

The biasing member is configured to upwardly bias the seat of the arm. A resilient ball is coupled to the seat.

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.
