Rotating and sliding boarding door assembly systems for a vessel and a vessel having the same
The present invention relates to a rotating and sliding boat boarding door mechanism configured to aid the vessel's occupants in their ingress and egress to and from the vessel. More particularly, the present invention provides a rotating and sliding boat boarding door assembly and system that slidingly moves into a recess in the vessel's exterior (e.g., side, transom, and/or gunwale) that has been configured to receive and maintain the boarding door assembly in a position where it is out of sight when fully recessed.
1. A rotating and sliding boarding door assembly for a boat, comprising:
an upper portion configured to be positioned in an opening in a boat hull when the assembly is in a closed position;
a lower portion configured to be positioned below said upper portion in the opening when the assembly is in the closed position;
one or more actuators coupled with said upper portion and said lower portion, said one or more actuators being configured to rotate and slide the upper and lower potions into a recess in a hull of the boat; and
one or more tracks, slideably coupled with at least one of the upper and lower portions, for guiding said at least one of the upper and lower portions into said recess.
2. The boarding door assembly as recited in claim 1 , further comprising a retractable recess cover to cover the recess in the hull when the door assembly is in a closed position.
3. The boarding door assembly as recited in claim 1 , wherein said upper portion is shaped to match a shape of the recess.
4. The boarding door assembly as recited in claim 3 , wherein said upper portion is shaped to match a cross-sectional shape of said recess.
5. The boarding door assembly as recited in claim 1 , wherein said upper portion is rotatably coupled with said lower portion.
6. The boarding door assembly as recited in claim 1 , further comprising a controller for controlling actuation of the one or more actuators, and said controller is configured to move said upper and lower portions between the closed position and the open position.
7. The boarding door assembly as recited in claim 6 , wherein the controller may be remotely controlled by a wireless remote control.
8. The boarding door assembly as recited in claim 1 , further including a step portion configured to be positioned to cover an exposed portion of the hull opening when the door is in the open position and to rotate upward into the cockpit to allow the door to be moved into the closed position.
9. The boarding door assembly as recited in claim 8 , further including a ram portion, positioned on a leading bottom edge of the lower portion, said ram portion being shaped to lift said step portion so that it rotates upward into the cockpit as the door moves into the closed position, and to lower said step portion to be positioned so as to cover the exposed portion of the hull opening when the door moves to the open position.
10. The boarding door assembly as recited in claim 1 , wherein said one or more actuators includes a first linear actuator for rotating said upper portion, a second linear actuator for securing said upper portion when the door assembly is in the closed position by extending at least one pin which can be secured into a recess in the hull, and a third actuator for sliding said lower portion and said upper portion, together, into the recess.
