Radio controlled boat lift
First Claim
1. In a boat lift for selectively raising and lowering a boat out of and into the water, the boat lift comprising at least one inflatable pontoon, a framework attached to and supported by said pontoon, valve means to control flow of air into and out of said pontoon for inflating and deflating same, and means to generate a supply of pressurized air for inflating said pontoon, the improvement comprising means to remotely actuate said valve means and pressurized air generation means to selectively inflate or deflate the pontoon from on board the boat, and thereby selectively, remotely, raise or lower the boat lift.

Abstract
A remote controlled boat lift comprises a remote transmitter unit that can selectively transmit one of two pre-determined RF signals, an up receiver and down receiver connected to operate a pressure pump system and valves for selectively inflating and deflating a pontoon supported framework for docking a boat.

- 4. A remote control for a pneumatically operated boat lift, said remote control being adapted for operation from on board a boat, said pneumatically operated boat lift comprising at least one inflatable pontoon, valve means to control flow of pressurized air into and out of said pontoon, and a pressure pump, the remote control comprising a transmitter having means to transmit one of two pre-determined signals, a receiver means, said receiver means being responsive to said transmitted signals, electrical control means connected to the valve means and pressure pump and responsive to said receiver means to either inflate the pontoon or deflate the pontoon in response to the signal received from the transmitter.

9. A remote controlled boat lift control for selectively raising or lowering a boat lift out of or into the water, said control being adapted for operation from on board a boat, the boat lift comprising a framework for supporting the boat, a pontoon secured to the framework, and a pressurized air supply, the boat lift control comprising:
- a transmitter having means to transmit one of two pre-determined signals;
a pair of receivers, each receiver being tuned to only one of the pre-determined signals;
a pair of electrically operable pneumatic valves, one of said valves being connected between the pressurized air supply and the pontoon to control the inflation thereof, the other of said valves being connected between the pontoon and the atmosphere to control the deflation thereof; and
a pair of relays, each of said relays being connected between one of the receivers and one of the valves so that as either one of the receivers responds to its tuned signal, its associated relay operates its associated valve to either inflate or deflate the pontoon to thereby raise or lower the boat lift. - View Dependent Claims (11)
