A fitness device is provided, the fitness device comprising: a spheroidal member having an interior cavity, the spheroidal member comprising a cylindrical portion extending between a first hemispherical endcap and a second hemispherical endcap, wherein a surface of the spheroidal member defines an aperture positioned between the interior cavity and an exterior of the spheroidal member; and a structured surface positioned on the surface of the spheroidal member over the aperture, the structured surface extending into the interior cavity of the spheroidal member.

A drive mechanism which is adapted for use with a swing device includes at least one electromagnetic driving unit and a control unit. The at least one electromagnetic driving unit is adapted to be pivotally connected to a bottom of the swing device. The control unit is electrically connected to the at least one electromagnetic driving unit for controlling the at least one electromagnetic driving unit to be activated and deactivated, so as to generate an intermittent magnetic force to drive swinging movement of the swing device. The swing device including the drive mechanism is also disclosed.

An infant seat includes a seat back member including an outer hub, a seat support member including an inner hub, a seat structure connected to the seat back member, and a locking mechanism including a slide gear and operably disposed on the seat back member. The inner hub is pivotably connected to the outer hub to make the seat back member rotatably connected to the seat support member for forming a cross bar structure. The slide gear is slidable within the outer and inner hubs for engaging with the outer and inner hubs to stop rotation of the inner hub on the outer hub. When the locking mechanism translates the slide gear to an unlocked position, the slide gear is disengaged from the outer hub to make the seat back member rotatable relative to the seat support member for adjusting a tilt angle of the seat structure.

An infant seat includes a seat back member having an outer hub, a seat support member, a base member and a seat structure pivoted to the seat back member and the seat support member, and a locking mechanism including a slide gear and operably disposed on the seat back member. The seat support member has an inner hub pivoted to the outer hub to make the seat back member rotatably connected to the seat support member. The slide gear is transversely slidable within the outer and inner hubs for engaging with the outer and inner hubs to stop rotation of the inner hub on the outer hub. When the locking mechanism translates the slide gear to the unlocked position, the slide gear is disengaged from the outer hub to make the seat back member rotatable relative to the seat support member for adjusting a tilt angle of the seat structure.

A drive mechanism which is adapted for use with a swing device includes two symmetrically-disposed electromagnetic driving units and a control unit. The electromagnetic driving units are adapted to be pivotally connected to a bottom of the swing device. The control unit is electrically connected to the electromagnetic driving units for controlling the electromagnetic driving units to be alternately activated and deactivated, so as to generate an intermittent magnetic force to drive swinging movement of the swing device. The swing device including the drive mechanism is also disclosed.

A move and discover chair helps teachers transition to new education paradigm where children “move” and “discover” education with the teacher positioned in the midst of the children to encourage them in the excitement of learning. The chair stimulates the ability to focus on learning and to be more effective in one's work by allowing some level of movement, balance, fidgeting, and engagement with the background environment. The chair includes a concave end cap with a first side edge and an external concave surface, a convex end cap with a second side edge and an external convex surface, and a center section fixedly positioned between the concave end cap and the convex end cap and with an outer surface that is substantially straight in a directions between the concave end cap and the convex end cap.

Modular furniture systems and methods. The modular furniture systems generally comprise a plurality of support surfaces and/or a plurality of support structures. Each support structure is configured to support the support surface above the ground or floor. In the depicted embodiments, the support surfaces are configured to hold and support a child or infant. In other embodiments, other support surfaces can be used such as tabletops. Generally, the support structures are releasably coupled to the support surface such that they can be assembled and disassembled by the user. The modular furniture system is configured such that each support surface is compatible with a variety of support structures. Similarly, each support structure can be compatible with a variety of support surfaces.

Sensory outputs are synchronized to input tempos for providing soothing and other effects for children and other persons. In example embodiments, juvenile products such as rockers and swings have motors that are controlled to produce an oscillatory motion with an adaptive tempo that is synchronized to rhythmic inputs such as a parent's heartbeat. In other example embodiments, juvenile products such as music players are controlled to output signals to play songs via speakers with an adaptive tempo that is synchronized to rhythmic inputs such as an infant's respiratory rate.

A swing seat includes a frame assembly and a seat assembly. The frame assembly includes a frame unit, and a rotating unit that is connected to a top end of the frame unit and that is rotatable relative to the frame unit about a swing axis which extends in an axial direction. The seat assembly includes a seat member, and a hanger arm. The hanger arm has a hanger portion coupled removably and co-movably to the rotating unit of the frame assembly, and a connecting portion interconnecting the hanger portion and the seat member, such that the seat member is swingable relative to the frame unit of the frame assembly about the swing axis.
