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.

A swing system may include a bucket-style swing seat, with a front support portion and a back support portion. A grip may be provided at the top edge of the outer face of the swing. The back support portion of the swing may have a height greater than the front support portion, and this high molded backing may also be provided with a top edge that curves outwardly. The high-molded backing may provide additional comfort for a child in the swing, as well as a grip for the caregiver pushing the swing.

An infant swing rocking chair includes a frame, two rocking bars and a chair assembly. The two front legs are arc posts protruding forward; the front legs and rear legs are hinged through the leg joint, and the front legs and the rear legs have two working positions of unfolding & supporting and folding; the rocking bar has the working position of rocking and the working position of locating; the bottom of each rocking bar is hinged with the chair assembly through the chair joint to make the chair assembly have the working position for the swing and the working position for the rocking chair; and the infant swing rocking chair has two use modes: a swing and a rocking chair.

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.

Disclosed is a swinging drive control apparatus, including a controller and a motor, where the controller detects a counter-electromotive force of the motor and drives the motor according to the detection result. Also disclosed is a corresponding method, including: measuring a counter-electromotive force of a motor in a previous cycle; and comparing a maximum counter-electromotive force value with a preset value, and calculating a PWM pulse duty factor in a next cycle. By directly detecting the counter-electromotive force of the motor without using a sensor, the present invention implements swinging frequency and phase tracking as well as swinging amplitude control, and simplifies a control system.

Presented here is an apparatus that includes a dual rail structure, an attachment mechanism, a child seat and upright supports. The apparatus can be 5 feet tall, 5 feet wide, and 2 feet deep. The upright supports lift the dual rail structure above the ground. The adjustable elastic cords can be connected to and suspended from the dual rail structure using wheels, which can traverse the dual rail structure. The child can be placed so that the child can walk, swing, and/or jump. The seat can rotate 360 with respect to the dual rail structure, enabling the child to change direction of motion within the dual rail structure. The entire apparatus can be collapsed using joints, which enable the bars of the apparatus to fold and/or disconnect for compact packing and easy transport.

The application relates to a vertically reciprocating cradle. The vertically reciprocating cradle comprises a mattress for bearing a baby and an elastic support structure for supporting the mattress, wherein the elastic support structure comprises a limiting plate, a middle connector and two elastic frames, and wherein each of the two elastic frames comprises an upper support frame and a lower limiting frame, the upper support frames of the two elastic frames are connected with the middle connector, and a limiting unit is formed on the limiting plate, and the two lower limiting frames are matched with the limiting unit, respectively; and wherein a connecting unit is formed at one end of a lower end surface of the mattress and connected with the middle connector, and the other end of the mattress is inclined downwards. The inclined mode enables the baby to be less prone to milk regurgitation.

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.
