Abstract: A combined suspension-safety support system and a children's jumper incorporated therewith. The combined suspension-safety support system comprises a primary suspension support system configured for suspending a child-receiving seat platform under normal operating conditions and a redundant secondary safety support system configured for engagement when the primary suspension support system fails.

Abstract: Track assemblies and track assembly kits for children's ride-on vehicles, as well as children's ride-on vehicle systems, according to the present disclosure are configured for assembly and disassembly of a track assembly. Track assemblies may include elongate rail members, couplers that are configured to couple together two elongate rail members, and optionally tie members that include one or more couplers. Generally, track assemblies comprise a left rail (including longitudinally aligned elongate rail members) and a right rail (including longitudinally aligned elongate rail members) in a spaced-apart and parallel relationship. Elongate rail members, couplers, and/or tie members are configured to releasably and repeatedly couple together. In the disassembled state, the component parts may be stored and/or shipped compactly. In the assembled state, the track assembly may define a track path, and the track assembly may be configured to guide the children's ride-on vehicle along the track path.

Abstract: A toy power tool is shown having a tool-holding housing and a handle housing rotatably connected at interfacing surfaces inclined to the central axes of both housings. Relative rotation of the housing about a transformation axis perpendicular to the inclined interfacing surfaces transforms the tool from one desired configuration to another. A 180.degree. rotation of the tool-holding housing relative to the handle housing transforms the tool between a straight configuration with the central axes of the housings being aligned, and a L-shaped configuration with the central axes of the housings being at right-angles. Detents between the interfacing surfaces position the housings at the desired configurations, and double as switches that are connected to a sound producing circuit on a printed circuit board mounted parallel to the interfacing surfaces. An internal gear mechanism converts linear input motion to the relative rotary motion of the housings.
