Abstract
A child motion device has a frame assembly configured to rest on a floor surface. A support arm assembly is coupled to and cantilevered from part of the frame assembly above the floor surface. A child supporting device is supported by the support arm assembly. A bounce mechanism of the device is employed to reciprocally bounce the child supporting device above the floor surface.
Claims22
A child motion device comprising:
- a frame assembly configured to rest on a floor surface;
- a bounce mechanism;
- a support arm assembly coupled by a four-bar linkage arrangement to and cantilevered from part of the frame assembly above the floor surface;
- and
- a child supporting device supported by the support arm assembly,
- wherein the bounce mechanism is part of the support arm assembly and includes an adjustable spring mechanism configured to move the four-bar linkage arrangement;
- and
- wherein the bounce mechanism is employed to reciprocally bounce the child supporting device above the floor surface.

A child motion device comprising:
- a frame assembly having a base section configured to rest on a floor surface that lies in a generally horizontal reference plane and having an upright section extending upward from a part of the base section;
- a bounce mechanism;
- and
- a support arm cantilevered radially outward from the upright section and coupled to the upright section by a four-bar linkage, the support arm being configured to support a child above the floor surface,
- wherein the bounce mechanism includes an adjustable spring mechanism is configured to move the four-bar linkage and impart a reciprocating bouncing motion to the child.
2 more elements
A child motion device comprising:
- a frame configured to rest on a floor surface that lies in a generally horizontal reference plane;
- a cantilevered arm with one end coupled via a four-bar linkage to a part of the frame and having a free end positioned above the floor surface, the free end of the support arm being moveable within a generally vertical plane;
- an adjustable spring coupled to the four-bar linkage;
- and
- a child supporting device on the arm spaced above the floor surface, wherein the adjustable spring can bounce the free end of the support arm in a reciprocating path within the generally vertical plane to thereby bounce the child supporting device.
