Appl. No.:

09/422394

Abstract:

A marine ladder includes a catch mechanism in which a catch tyne is directly secured to the marine ladder without the need for additional structural members or support. The catch tyne is formed as a substantially L-shaped member that dependingly connects to a transverse bar on the dock-anchored frame of the ladder and defines a channel for receiving a leg of a user-selected one of the un-shaped rungs on an elongated ladder portion. The ladder portion is slidably engageable with and along the anchored frame to thereby selectively adjust the height of the ladder and thereby accommodate ready movement of persons between a dock and a proximate watercraft disposed at relatively different elevations.

Abstract:

A swing ladder has a mounting bracket and a ladder body pivotally connected to the mounting bracket. The bracket has a pinhole formed therein and a release pin secured thereto. The ladder body includes a long section with steps, a short section parallel to the long section, and a curved section connecting the short section and the long section. The short section of the ladder body has two pinholes formed therein on each side of the connecting device. The release pin is inserted into the pinhole in the bracket and one of the two pinholes in the short section of the ladder body for locking the ladder body in a down position or an up position.
