| 20150291262 | RETRACTABLE MARINE BOARDING LADDER - The present system is directed in various embodiments to marine ladders comprising movement assistance for the transition from a deployed position to a stowed position and to assist in controlling the transition from the stowed position to the deployed position. In certain embodiments, the gas springs and associated pivot point brackets hold the deployed ladder biased in the deployed position with a biasing force that may be overcome by application of force by the user to initiate an automatic stowing process. The initial force to initiate the stowing process is provided by the force of water flowing against an aft-mounted ladder as a result of the boat moving forward. In the case of movement assistance from the stowed to deployed position, the user applies force to initiate the transition while the gas springs apply an opposing force that slows the transition for safety. | 10-15-2015 |
