Method and device for rocking baby cribs, strollers and other objects on wheels
A motor with apparatus comprising a series of connected links to change the circular motion of the motor to a linear motion and from the linear motion to a continuous oscillation to and fro which motion is transferred to an arc shaped rocker cradle. A wheel of the stroller or other object sits in the rocker cradle and the stroller or other object is thereby rocked to and fro.
This invention is in the field of rocking equipment and in particular a device that may be applied to baby strollers, cribs and other wheeled objects that rock the stroller, crib or other object, for example, to comfort a baby and assist it to fall asleep.
BACKGROUND OF THE INVENTIONMany patents have revealed a wide range of methods and devices to assist babies to fall asleep. Examples of such inventions are Australian Patent No. 2131483 and U.S. Pat. No. 6,519,792 issued to Chen both of which patents are bulky and less portable than the present invention. U.S. Pat. No. 5,002,144 issued to McMahon attempts to provide an orbital movement rather than the simpler to and fro movement.
This innovation is another and unique device that combines novelty, versatility to fit a wide range of styles, kinds, and manufactures of baby strollers, cribs and other wheeled objects.
SUMMARY OF THE INVENTIONIt is to be understood that both the foregoing general description and the following detailed description present embodiments of the invention and are intended to provide an overview or framework for understanding the nature and character of the invention as it is claimed. The accompanying drawings are included to provide a further understanding of the invention and are incorporated into and constitute a part of this specification. The drawings illustrate various embodiments of the invention and, together with the description, serve to explain the principles and operations of the invention but not to limit the invention to these descriptions only.
This invention comprises a motor with apparatus comprising a series of connected links to change the circular motion of the motor to a linear motion and from the linear motion to a continuous oscillation to and fro which motion is transferred to an arc shaped rocker cradle. A wheel of the stroller or other object sits in the rocker cradle of this invention and the stroller or other object is thereby rocked gently to and fro.
The power could be supplied from mains electricity or from batteries and a timer device could enable the rocking to switch off after a chosen amount of time. The rocking cradle is easily transferable and transportable and is made to fit virtually any size wheel used for strollers, cribs and other wheeled objects without special adaptor devices.
There could be a gear to make the rocking faster and slower while the motor rotates at a constant speed. There could be a physical stopper at both ends of the rocking cradle to prevent the stroller or crib wheel from exiting from the rocking cradle unintentionally.
The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments of the invention and together with the description, serve to explain by way of example only, the principles of the invention:
As will be appreciated the present invention is capable of other and different embodiments than those discussed above and described in more detail below, and its several details are capable of modifications in various aspects, all without departing from the spirit of the invention. Accordingly, the drawings and description of the embodiments set forth below are to be regarded as illustrative in nature and not restrictive.
At the distal end of the connecting rod 136 is a pin that slides in a slit in the motor stand and slit 123. The slit is not visible in
There is a slit 154 in which a connector pin slides up and down.
Claims
1. A method and device for rocking baby strollers, cribs and other wheeled objects comprising,
- a. a power source to provide electric power to a motor,
- b. a motor that turns a disc drive,
- c. a bearing a-centrically positioned in the said disc drive,
- d. a connecting arm attached at one end to the said a-centric bearing and at the other end to a bearing in a groove via a static slit,
- e. a grooved arm housing the said bearing in the said groove pivotally moved back and forth making a rocking movement,
- f. a means to connect the said grooved arm to a rocking cradle into which can be placed the wheel of a child's carriage, stroller or other wheeled object,
- whereby the rotating movement of a motor is transposed into linear movement and the linear movement is transposed into a rocking movement to enable a motor to rock a child's crib, stroller or other wheeled object.
2. A method and device for rocking baby strollers, cribs and other wheeled objects as claimed in claim 1 wherein there is a physical stopper in the said rocking cradle to prevent the said wheel from being rocked out of the said rocking cradle.
3. A method and device for rocking baby strollers, cribs and other wheeled objects as claimed in claim 1 wherein the said power source is mains electricity.
4. A method and device for rocking baby strollers, cribs and other wheeled objects as claimed in claim 1 wherein the said power source is at least one battery.
5. A method and device for rocking baby strollers, cribs and other wheeled objects as claimed in claim 1 wherein the speed of the rocking of the said rocking cradle is determined by a gear mechanism.
6. A method and device for rocking baby strollers, cribs and other wheeled objects as claimed in claim 5 wherein the said speed is varied with the aid of resistors in the electrical circuit.
7. A method and device for creating a rocking movement comprising,
- a. a power source to power a motor that turns a disc,
- b. an acentric connection from the said disc to a pivoted groove via a static slit, thereby creating a rocking movement in the said pivoted groove as the said motor turns.
