초록 ▼

A preferred embodiment of a combination boat lift and dock 10 is described having two spaced pontoons with an intermediate boat support 18. Pivot arm structures 20, 22 pivotally interconnect the boat support 18 with the pontoons. A drive mechanism 24 is connected to the pivot arm structures 20, 22 for pivoting the arm structures downward and inward to move at least one of the pontoons laterally inward toward the other pontoon to raise the boat support to lift a stored boat out of the water. The drive mechanism 24 is also designed to pivot the arm structures upward and outward to move at least one of the pontoons away form the other pontoon to lower the boat support 18 and lowering the boat into the water. The arm structures are pivotally connected to the underside of the pontoons. The dock 10 further includes a pontoon stabilizing mechanism 26 for preventing the pontoons from rocking or tilting.

[ I claim:] [1.] A combination boat lift and dock comprising:a boat dock comprising two floating pontoons spaced on opposite sides of a longitudinal dock axis a sufficient distance to receive a boat there between; in which at least one of the pontoons being movable laterally toward and away from the other pontoon;a central boat support between the pontoons and extending along the longitudinal axis normally beneath the floating boat;said boat support being movable between a lower substantially submerged position beneath the floating boat and an elevated position supporting the boat above the water surface;lateral pivot arms extending between the boat support and the pontoons with inner ends of the arms being pivotally connected to the boat support for pivotal movement about pivot axes on opposite sides of the longitudinal axis and with outer ends of the arms being operatively connected to the pontoons; anddrive mechanism operatively connected to the pivot arms for (1) pivoting the arms downward and inward about the pivot axes moving at least one of the pontoons inward toward the other pontoon thereby raising the pivot axes and lifting the boat support from the lower position to the elevated position to lift the received boat above the water surface; and (2) permitting the arms to pivot upward and outward causing the one pontoon to move laterally away from the other pontoon to move the boat support from the elevated position to the lower position to lower the received boat into the water.
