The pump includes a cover mounted to a body of the pump and selectively configurable between open and closed positions. In the open position, air is allowed to flow between the inflatable chamber and the ambient air through the pump body. When the cover is closed, the air chamber of the inflatable product is sealed with respect to the ambient air such that air is retained within the inflatable chamber when inflated. A power switch is positioned to be deactivated by the cover when the cover is mounted to the body of the pump, such that replacement of the cover during inflation or deflation of the inflatable product automatically deactivates the pump. ## Claims ### Claim 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 a motor driving an air mover, the 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, the switch comprising 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, the double pole double throw 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; 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. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 1) The inflatable product of claim 1, wherein the motor comprises: an output shaft; the air mover fixed to the output shaft and configured to move the air upon activation of the motor. ### Claim 4 (depends on 3) 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 the electrical current from flowing to the motor in the deactivated position. ### Claim 5 (depends on 4) 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. ### Claim 6 (depends on 1) The inflatable product of claim 1, 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. ### Claim 7 (depends on 6) The inflatable product of claim 6, wherein the switch selectively makes an electrical connection between the motor and a rechargeable battery mounted in the housing of the pump. ### Claim 8 (depends on 3) The inflatable product of claim 3, wherein the air mover comprises an axial-flow fan. ### Claim 9 (depends on 8) The inflatable product of claim 8, wherein the pump further comprises a baffle cover mounted on the housing and disposed between the axial-flow fan and the interior product chamber. ### Claim 10 (depends on 1) 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. ### Claim 11 (depends on 1) 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. ### Claim 12 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; 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; and 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.
