Patio dive doors for marine vessels having a swim step assembly
A marine vessel has a hull and a swim patio which is movable into a closed position in which the swim patio closes the hull and into an open position in which the swim patio provides platform on which a person can stand and dive into the water. The swim patio comprises a swim step assembly which is movable relative to the swim patio into and between a stowed position in which the swim step assembly is hidden in the swim patio and a deployed position in which the swim step assembly extends downwardly from the swim patio in the open position for the person to climb into or out of the water.

2 . The marine vessel according to claim 1 , wherein the swim patio is pivotable into the closed position and into the open position.
3 . The marine vessel according to claim 2 , wherein the swim patio comprises a lower end and wherein the swim patio pivots about the lower end.
4 . The marine vessel according to claim 3 , further comprising an actuator configured to automatically pivot the swim patio into the closed position and the open position.
5 . The marine vessel according to claim 2 , wherein the inner hull sidewall is pivotable relative to the hull into the closed position and the open position, the inner hull sidewall providing the platform in the open position.
6 . The marine vessel according to claim 5 , wherein the swim step assembly comprises a frame assembly which in the stowed position is entirely hidden in the swim patio.
7 . The marine vessel according to claim 6 , wherein the outer hull sidewall is coupled to the inner hull sidewall by the frame assembly, and wherein the frame assembly is retractable and extendable to position the swim step assembly in the stowed position and the deployed position, respectively.
8 . The marine vessel according to claim 7 , wherein the frame assembly in the stowed position is enclosed in a cavity which is at least partially defined by the inner hull sidewall and the outer hull sidewall.
9 . The marine vessel according to claim 7 , wherein the frame assembly comprises a base frame which is fixed to the inner hull sidewall and frame linkage which is pivotably coupled to the base frame and pivotably coupled to the outer hull sidewall.
10 . The marine vessel according to claim 7 , further comprising an actuator configured to automatically move the swim step assembly into the stowed position and the deployed position.
11 . The marine vessel according to claim 10 , wherein the actuator comprises a hydraulic actuator.
12 . The marine vessel according to claim 10 , wherein the actuator comprises a linear actuator.
13 . The marine vessel according to claim 1 , wherein the swim patio in the stowed position is flush with the hull.
14 . The marine vessel according to claim 13 , wherein the inner hull sidewall is pivotable relative to the hull into the closed position and the open position, the inner hull sidewall providing the platform in the open position and wherein the swim step assembly comprises a frame assembly which in the stowed position is entirely hidden in the swim patio.
15 . The marine vessel according to claim 13 , wherein the inner hull sidewall is pivotable relative to the hull into the closed position and the open position, the inner hull sidewall providing the platform in the open position, wherein the swim step assembly comprises a frame assembly which in the stowed position is entirely hidden in the swim patio, and wherein in the deployed position the outer hull sidewall provides a lower swim step of the swim step assembly.
16 . The marine vessel according to claim 15 , wherein the swim step assembly further comprises an intermediate swim step located between the platform and the lower swim step.
17 . The marine vessel according to claim 15 , wherein the frame assembly in the stowed position is fully enclosed in a cavity which is at least partially defined by the inner hull sidewall and the outer hull sidewall.
18 . A marine vessel for operating in a body of water, the marine vessel comprising:
a hull; and
a swim patio having a swim step assembly, wherein the swim patio is movable into a closed position in which the swim patio closes the hull and into an open position to provide a platform on which a person can stand and dive into the water, wherein the swim step assembly comprises an inner hull sidewall and an outer hull sidewall movably coupled to the inner hull sidewall, wherein the swim step assembly is movable relative to the swim patio into and between a stowed position in which the swim step assembly is at least partially hidden in the swim patio and a deployed position in which the swim step assembly extends downwardly from the swim patio in the open position for the person to climb into or out of the water, wherein the outer hull sidewall is unhidden when the swim patio is in both the stowed position and the deployed position, and wherein in the deployed position the outer hull sidewall provides a lower swim step of the swim step assembly.
19 . The marine vessel according to claim 18 , wherein the swim step assembly further comprises an intermediate swim step located between the platform and the lower swim step.
20 . A marine vessel for operating in a body of water, the marine vessel comprising:
a hull; and
a swim patio having a swim step assembly, wherein the swim patio is movable into a closed position in which the swim patio closes the hull and into an open position to provide a platform on which a person can stand and dive into the water, wherein the swim step assembly comprises an inner hull sidewall and an outer hull sidewall movably coupled to the inner hull sidewall, wherein the swim step assembly is movable relative to the swim patio into and between a stowed position in which the swim step assembly is at least partially hidden in the swim patio and a deployed position in which the swim step assembly extends downwardly from the swim patio in the open position for the person to climb into or out of the water, wherein the outer hull sidewall is pivotably coupled to the inner hull sidewall as a four-bar mechanism such that the outer hull sidewall is unhidden when the swim patio is in both the stowed position and the deployed position.
