Abstract: A collaborative play toy generally includes a plurality of satellite assemblies capable of a first movement and a second movement, and a center assembly coupled to the plurality of satellite assemblies. The center assembly is configured to move in response to the first movement of a first satellite assembly and to create a second movement in a second satellite assembly.

Abstract: A playground device, in the nature of a teeter-totter, includes first and second spaced base members. An arcuate rail is coupled to the base members in an upright arc. An arcuate member surrounds at least a portion of the rail and is mounted for to-and-fro movement relative to the rail. User platforms or other user-friendly features are mounted on the tube. A biasing mechanism coacts between the member and the rail to bias the member toward a predetermined preferably central position on the rail, while allowing the tube to move to-and-fro on the rail.

Abstract: A playground apparatus (10) for children to slide across while hanging by their hands is disclosed. The apparatus includes a support structure (12, 16, and 20) holding multiple rails (18), preferably five, horizontally above the ground and above the heads of the children. The rails are generally parallel one to another and include gentle curves along their length. Handhold assemblies (22) are slidably coupled to each of the rails and include two grips (40) on each assembly for users' hands. The grips are disposed below the rails and the handhold assemblies include partitions (46) between the rails and the grips to protect the children's hands from the rails. The handhold assemblies include channels (44) in which the rails are received and allowed to slide. The channels are wider in their middle portions than at their ends to accommodate the curves in the rails.

Abstract: In accordance with the present invention, a playground carriage (10) is provided for moving people (100) from one play area to another. The playground carriage comprises a rotatable support pipe (12) having a first end (14) and a second end (16). The support pipe extends between a first vertical column (18) and a second vertical column (20). A manually-operated crank (22) having a first end (24) and a second end (26) is also included. The manually-operated crank extends between the first vertical column and a third vertical column (48). The first end of the crank is coupled to the first end of the support pipe so that manually turning the crank rotates the support pipe. A carriage (28) for carrying people is mounted to the support pipe. The carriage is advanced along the support pipe by a carrier (30).
