Electromagnetic children's bouncer
View Patent ↗Various embodiments of the present invention are directed to a children's bouncer apparatus. In various embodiments, the apparatus includes a support frame, seat assembly configured to support a child, and bouncer control device. The support frame includes one or more semi-rigid support arms that extend above a base portion and suspend the seat assembly above the base portion. The bouncer control device is configured to impart a driving force on the seat assembly via a magnetic drive assembly, thereby causing the seat assembly to continuously oscillate at the natural frequency of the children's bouncer.

a first magnetic component operatively connected to the housing;
a second magnetic component operatively connected to the mobile member such that the second magnetic component moves toward and away from the first magnetic component as the mobile member pivots, wherein at least one of the first magnetic component and second magnetic component comprises an electromagnet configured to create a magnetic force with the other of the first and second magnetic components when supplied with electric current;
a power supply configured to transmit electric current to the electromagnet; and
a bouncer control circuit configured to generate a control signal that causes the power supply to supply electric current to the electromagnet and thereby generate a magnetic force causing the mobile member to oscillate within the housing.
2. The bouncer control device of claim 1 , wherein the second magnetic component comprises the electromagnet.
3. The bouncer control device of claim 1 , wherein the first magnetic component comprises one or more permanent magnets.
4. The bouncer control device of claim 1 , wherein the mobile member includes a free end and a pivoting end, the pivoting end of the mobile member being pivotally connected to a portion of the housing and the free end of the mobile member being configured to move toward and away from the first magnetic component as the mobile member oscillates; and
wherein the second magnetic component is affixed to the free end of the mobile member.
5. The bouncer control device of claim 4 , wherein one or more weights are affixed to the free end of the mobile member.
6. The bouncer control device of claim 1 , further comprising:
a reciprocating device configured to impart a reciprocating force on the mobile member that drives the mobile member in a direction substantially opposite to the direction in which the magnetic force generated by the first and second magnetic components drives the mobile member.
7. The bouncer control device of claim 6 , wherein the reciprocating device comprises one or more springs.
8. The bouncer control device of claim 7 , wherein the one or more springs are affixed to the housing and positioned to engage the free end of the mobile member.
9. The bouncer control device of claim 1 , wherein the second magnetic component is repelled from the first magnetic component when the electromagnet is energized.
10. The bouncer control device of claim 1 , wherein the second magnetic component is attracted to the first magnetic component when the electromagnet is energized.
11. The bouncer control device of claim 1 , wherein the housing is configured to be removably affixed to the children's bouncer.
12. The bouncer control device of claim 1 , further comprising a bouncer frequency sensor configured to sense the natural frequency of the children's bouncer; and
wherein the bouncer control circuit is configured to supply electric current to the electromagnet such that that the mobile member oscillates at the sensed natural frequency.
13. The bouncer control device of claim 1 , wherein the bouncer control circuit is further configured to receive user input indicating a desired amplitude of motion for the children's bouncer and, based on the user input, supply electric current to the electromagnet such that the amplitude of the mobile member's oscillation corresponds to the desired bouncer amplitude.
14. A children's bouncer apparatus for providing a controllable bouncing seat for a child, the apparatus comprising:
a seat assembly for supporting a child;
a support frame configured to support the seat assembly, the support frame comprising:
a base portion configured to rest on a support surface;
one or more resilient support arms extending upwardly from the base portion to suspend the seat assembly above the support surface, the one or more support arms being configured to flex in order permit the seat assembly to oscillate in response to a motive force; and
a bouncer control device comprising:
a housing secured to at least one of the one or more support arms; and
a magnetic drive assembly positioned within the housing and comprising at least one electromagnet and a mobile member configured to oscillate relative to the housing, the electromagnet being configured to generate a magnetic force causing the mobile member to oscillate and thereby impart a motive force that causes the seat assembly to oscillate.
15. The children's bouncer of claim 14 , wherein the mobile member is operatively connected to the housing and configured to pivot relative to the housing.
16. The children's bouncer of claim 15 , wherein the magnetic drive assembly comprises:
a first magnetic component operatively connected to the housing;
a second magnetic component operatively connected to the mobile member such that the second magnetic component moves toward and away from the first magnetic component as the mobile member pivots, wherein at least one of the first magnetic component and second magnetic component comprises the electromagnet and is configured to create a magnetic force with the other of the first and second magnetic components when supplied with electric current;
a power supply configured to transmit electric current to the electromagnet; and
a bouncer control circuit configured to generate a control signal that causes the power supply to supply electric current to the electromagnet and thereby generate a magnetic force causing the mobile member to oscillate within the housing.
17. The bouncer control device of claim 16 , wherein the second magnetic component comprises the electromagnet.
18. The bouncer control device of claim 16 , wherein the first magnetic component comprises one or more permanent magnets.
