Abstract
A swing with a pivotably attached tray for pivotable movement about a generally vertical axis, a vibrating mechanism attachable to a seat bottom of the swing, wheels mounted on a frame for selective engagement with the floor when the frame is tilted back when grasping a pair of handles on the frame, a lost motion coupling mechanism for a motorized drive mechanism, and a reclinable seat with an adjustment wire for selecting different reclined positions.
Claims17
A motorized swing for a child, comprising:
- a support structure;
- a child support, including a hanger arm extending from a child seat, the hanger arm being pivotably attached at an end distal from the child seat to the support structure;
- and
- a drive mechanism including:
- a motor assembly connectable to a power source, the motor assembly producing reciprocating motion;
- and
- a lever coupled to the motor assembly at a first end, the lever coupled to the hanger arm at a second end, and the lever converting the reciprocating motion from the motor assembly to a pivoting motion in the hanger arm and child seat.
4 more elements
A motorized swing for a child, comprising:
- a support structure having a left side and a right side, with a cylindrical opening defined in each side;
- a child support pivotably attachable to the support structure, the child support including a pair of axles, journaled in the respective cylindrical openings in the respective sides of the support structure, a pair of arms, directly connected to the respective axles, and a seat connected to and supported by the pair of arms;
- and
- a drive mechanism couplable to the support structure and the child support, the drive mechanism including:
- a motor assembly connectable to a power source, the motor assembly producing reciprocating motion;
- and
- a lever coupled to the motor assembly at a first end, and the lever coupled to one of the pair of axles at a second end, the lever converting the reciprocating motion from the motor assembly to pivoting motion in the pair of arms and the seat.

A motorized swing for a child, comprising:
- a support structure;
- a child support, including a hanger arm extending from a child seat, the hanger arm being pivotably attached at an end distal from the child seat to the support structure;
- and
- a drive mechanism including,
- a motor assembly connectable to a power source, the motor assembly producing reciprocating motion;
- and
- a lever coupled to the motor assembly at a first end, the lever coupled to the hanger arm at a second end, and the lever converting the reciprocating motion from the motor assembly to a pivoting motion in the hanger arm and child seat;
- wherein the lever is coupled to the motor assembly by a gear on a drive shaft of a motor, the gear rotating a wheel which is pivotably coupled to an actuator which imparts pivoting motion to the lever;
- and
- wherein the actuator is an elongated slotted housing that is moved in a substantially longitudinal manner, the housing receiving a portion of the lever within the slot.

A motorized swing for a child, comprising:
- a support structure;
- a child support, including a hanger arm extending from a child seat, the hanger arm being pivotably attached at an end distal from the child seat to the support structure;
- and
- a drive mechanism including,
- a motor assembly connectable to a power source, the motor assembly producing reciprocating motion;
- a lever coupled to the motor assembly at a first end, the lever coupled to the hanger arm at a second end, and the lever converting the reciprocating motion from the motor assembly to a pivoting motion in the hanger arm and child seat;
- and
- an angular position sensor disposed relative to the support structure and the child support to sense position information relating to the pivotable position of the child support relative to the support structure, the sensor being operative to generate a signal indicative of the position information to the motor assembly.

A motorized swing for a child, comprising:
- a support structure,
- a child support, including a hanger arm extending from a child seat, the hanger arm being pivotably attached at an end distal from the child seat to the support structure;
- and
- a drive mechanism including,
- a motor assembly connectable to a power source, the motor assembly producing reciprocating motion;
- and
- a lever coupled to the motor assembly at a first end, the lever coupled to the hanger arm at a second end, and the lever converting the reciprocating motion from the motor assembly to a pivoting motion in the hanger arm and child seat;
- wherein the power source to which the motor assembly is connectable is a battery having a battery voltage at a nominal level, and further wherein the motor assembly includes a drive circuit that maintains a constant amplitude for the pivotable motion of the child support as the battery voltage decreases from the nominal voltage to 75% of the nominal voltage.
