Watercraft swim platform with deployable steps
Boats can include a swim platform with an integrated system of steps that can be selectively deployed and retracted. Such platforms can be attached to a transom of a boat or can be fabricated as an extended portion of the boat's hull. In another embodiment, deployable steps can be integrated with a boat's hull as a side-entry door. In order to reconfigure the step system into a deployed configuration, a linkage is actuated that causes the step system to unfold, forming steps (or a seating configuration) at least partially below the water line. Since the steps can be deployed below the water line, a swimmer can more easily get on board the boat.
1. A deployable step system for a watercraft, the system comprising:
a first platform;
a second platform; and
a linkage movably coupling the first and second platforms together such that the system is reconfigurable from a retracted configuration to a deployed configuration in which the first and second platforms each move to create steps,
wherein the first platform is above the second platform while the system is in the retracted configuration,
wherein the first platform is below the second platform while the system is in the deployed configuration, and
wherein as the system reconfigures from the retracted configuration to the deployed configuration: (i) the first platform pivots by at least ninety degrees and (ii) the second platform pivots less than 90 degrees.
2. The system of claim 1 , further comprising an actuator coupled to the linkage and operable to drive reconfiguration of the system between the retracted configuration and the deployed configuration.
3. The system of claim 2 , wherein the actuator is a linear actuator.
4. The system of claim 2 , wherein the linkage includes a hard stop such that while the system is in use in the deployed configuration the hard stop bears forces applied by the use rather than the actuator.
5. The system of claim 1 , further comprising a swim platform with which the system is integrated, the swim platform configured for extending from a transom of a boat.
6. The system of claim 5 , further comprising a first upright panel disposed between the second platform and the swim platform while the system is in the deployed configuration.
7. The system of claim 6 , further comprising a second upright panel disposed between the first and second platforms while the system is in the deployed configuration.
8. A watercraft deployable step system, comprising:
a first platform;
a second platform;
a linkage configured to connect both of the first platform and the second platform to a boat, wherein:
the linkage is connected to each of the first platform and the second platform in a manner that (i) enables the first platform to rotate at least ninety degrees between a retracted state to a deployed state, and (ii) enables the first platform to transition from a location that is above the second platform in the retracted state to a location that is below the second platform in the deployed state; and
each of the first platform and the second platform are located below a swim platform of the boat in the deployed state;
a swim platform with which the deployable step system is integrated, the swim platform configured for extending from a transom of a boat; and
a first upright panel disposed between the second platform and the swim platform while the system is in the deployed state.
9. The system of claim 8 , further comprising an actuator coupled to the linkage and operable to drive reconfiguration of the system between the retracted state and the deployed state.
10. The system of claim 9 , wherein the actuator is a linear actuator.
11. The system of claim 9 , wherein the linkage includes a hard stop such that while the system is in use in the deployed state the hard stop bears forces applied by the use rather than the actuator.
12. The system of claim 8 , further comprising a second upright panel disposed between the first and second platforms while the system is in the deployed configuration.
13. A watercraft swim platform system, comprising:
a swim platform with an upper surface; and
a deployable step system integrated with the swim platform and comprising:
a first platform;
a second platform;
a linkage movably coupling the first and second platforms together such that the system is reconfigurable between: (i) a retracted configuration in which the first platform forms a portion of the upper surface of the swim platform and (ii) a deployed configuration in which the first and second platforms create two steps that are each below the upper surface of the swim platform; and
a first upright panel disposed between the second platform and the swim platform while the system is in the deployed configuration.
14. The system of claim 1 , further comprising a linear actuator coupled to the linkage and operable to drive reconfiguration of the system between the retracted configuration and the deployed configuration, and
wherein the linkage includes a hard stop such that while the system is in use in the deployed configuration the hard stop bears forces applied by the use rather than the actuator.
15. The system of claim 13 , wherein as the system reconfigures from the retracted configuration to the deployed configuration: (i) the first platform pivots by at least ninety degrees and (ii) the second platform pivots less than 90 degrees.
16. The system of claim 13 , further comprising a second upright panel disposed between the first and second platforms while the system is in the deployed configuration.
