Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

WHAT IS CLAIMED IS:

1. An inflatable product, comprising:

a product body defining a sealed interior product chamber; and

a pump comprising:

a housing mounted to the product body and defining an interior housing chamber having an inner end in fluid communication with the interior product chamber and an outer end in fluid communication with ambient air around the product body;

an air mover assembly having an activated configuration and a deactivated configuration;

a switch having an activated position which causes the air mover assembly to activate, and a deactivated position which causes the air mover assembly to deactivate; and

a cover sized and configured to mount to the outer end of the housing to seal the interior housing chamber in a closed position, and to allow air to flow through the outer end in an open position, the cover having a switch activator configured to place the switch in the deactivated position as the cover is advanced from the open position to the closed position.

2. The inflatable product of claim 1, wherein the activated position of the switch includes a pair of activated positions respectively corresponding to an inflation and deflation of the inflatable product.

3. The inflatable product of claim 1, wherein the air mover assembly comprises:

a motor having an output shaft;

an air mover fixed to the output shaft and configured to move air upon activation of the motor.

4. The inflatable product of claim 3, wherein the switch is configured to allow electrical current to flow to the motor in the activated position, and to prevent electrical current from flowing to the motor in the deactivated position.

5. The inflatable product of claim 4, further comprising a power supply mounted to the

housing, the power supply selectively electrically connected to the motor via the switch.

6. The inflatable product of claim 5, wherein:

the switch comprises a double pole double throw switch having a first switch portion which activates a first switch terminal to make a first electrical connection to the motor, the first electrical connection driving the air mover in a first direction; and

the double pole double throw switch having a second switch having a second switch portion which activates a second switch terminal to make a second electrical connection to the motor, the second electrical connection driving the air mover in a second direction opposite the first direction.

7. The inflatable product of claim 6, wherein the switch activator includes a first leg oriented to engage the first switch portion and a second leg oriented to engage the second switch portion when the cover is in the closed position.

8. The inflatable product of claim 7, wherein the switch selectively makes an electrical connection between the motor and a rechargeable battery mounted in the housing of the pump.

9. The inflatable product of claim 3, wherein the air mover comprises an axial-flow fan.

10. The inflatable product of claim 9, wherein the pump further comprises a baffle cover mounted on the housing and disposed between the axial-flow fan and the interior product chamber.

11. The inflatable product of claim 1, wherein the pump further comprises a resilient O-ring mounted on the cover and positioned to be disposed between the cover and the housing when the cover is in its closed position, such that the O-ring seals the interior housing chamber from the ambient air.

12. The inflatable product of claim 1, further comprising an auxiliary air supply mounted on the product body and in fluid communication with the interior product chamber, the auxiliary air supply having an internal chamber, the auxiliary air supply compressible to discharge air from the internal chamber to the interior product chamber.

13. A pump for use in connection with inflatable products, the pump comprising:

a housing defining an interior housing chamber having an open inner end and an open outer end opposite the inner end;

a motor mounted to the housing;

an air mover fixed to the motor and driven by the motor when the motor is activated; a power supply mounted to the housing;

a switch having electrically connected to the motor and the power supply, the switch having an activated position in which electrical current is allowed to flow from the power supply to the motor, and a deactivated position in which electrical current is prevented from flowing from the power supply to the motor; and

a cover sized and configured to mount to the outer end of the housing to seal the interior housing chamber in a closed position, and to allow air to flow through the outer end in an open position, the cover having a switch activator configured to place the switch in the deactivated position as the cover is advanced from the open position to the closed position.

14. The pump of claim 13, wherein the power supply comprises a battery.

15. The pump of claim 13, wherein the power supply comprises a power port configured to be connected to an external source of electrical power.

16. A method of inflating an inflatable product, the method comprising:

opening a cover to establish a fluid communication between an interior chamber of the inflatable product and ambient air;

activating a pump to direct a flow of air between the interior chamber and the ambient air; and

closing the cover to seal the interior chamber of the inflatable product from the ambient air, the step of closing the cover simultaneously deactivating the pump.

17. The method of claim 16, wherein:

the step of activating the pump comprises actuating a switch contained within a pump housing into a first switch configuration; and

the step of deactivating the pump comprises actuating the switch into a second switch configuration.

18. The method of claim 17, wherein:

the step of actuating the switch contained into the first switch configuration is done manually by an operator; and

the step of actuating the switch contained into the second switch configuration is done by the abutting the switch with a portion of the cover as the cover is closed.

19. The method of claim 16, wherein the step of activating the pump comprises turning an axial fan of the pump in a first direction to direct the flow of air into the interior chamber from the ambient air, whereby the inflatable product is inflated.

20. The method of claim 19, further comprising activating the pump to turn the axial fan of the pump in a second direction opposite the first direction to direct the flow of air from the interior chamber toward the ambient air, whereby the inflatable product is deflated.
