Boat driver door and ladder assembly

Abstract

A dive door and ladder assembly includes a door positioned on the side of a boat, preferably in a rearward or aft position. The dive door is attached to a horizontally oriented hinge on a bottom portion thereof, and opens by pivoting inwardly and downwardly (vertically). When the door is in an open position, the underside of the door is generally in a horizontal plane with the upper surface of the doorway, forming a platform for divers and snorkelers to stand on. The upper surface of the doorway further includes a small hatch that may be opened to reveal a compartment therebelow. A collapsible ladder may be positioned within the compartment, in a collapsed state, and may be pulled upwardly from the compartment and folded over the side of the boat, through the doorway and extended into the water.

DETAILED DESCRIPTION OF THE INVENTION

(11) The present invention includes, in a first embodiment, a diver door 10 that includes a hinge on a bottom portion thereof, so that the diver door opens inwardly and swings downwardly in a vertical direction. When the door 10 is in the open position, the bottom surface 12 of the door forms a platform 14 that is generally in the same plane as the upper surface of the doorway 16, as shown in FIG. 1. The platform 14 is preferably raised above the level of the deck, so that a user may step up onto the platform 14 from the deck of the boat prior to entering the water. In a preferred embodiment, the upper surface of the doorway 16 includes a hinged hatch 18 that may be opened to reveal a compartment 20 below the doorway. A collapsible ladder 22 is positioned within the compartment 20 in a collapsed state, and the ladder 22 may be pulled upwardly from the compartment 20, as shown in FIGS. 4 and 6, and folded over the side of the boat and extended downwardly into the water, as shown in FIGS. 1 and 5.

(12) The diver door 10, in a preferred embodiment, has a thickness equal to that of the side of the boat, so that the outer surface of the door is flush with the outer hull, and the inner surface of the door is flush with the inner surface of the side wall of the boat, as shown in FIG. 2. Optionally, a strip of sealing material, such as rubber, silicone, or the like, may be positioned between the door and the doorway (when the door is in a closed position), in order to prevent water from leaking through the seams between the door and doorway. One or more latches 24 may lie placed in any desired position for locking the door 10 into a closed position. A pair of latches 24 are shown on an upper surface of the door 10 in FIG. 2.

(13) The compartment 20 preferably includes a hinged compartment hatch 18 that may be opened in order to pull the ladder 22 out or place the ladder 22 back in, as shown in FIGS. 4 and 6. Otherwise, when the ladder 22 is either in the storage position, or is in the operable position extending down into the water, the hatch 18 may be closed in order to provide a platform for divers and snorkelers to stand on. The platform 14 is formed by the upper surface 16 of the doorway (and compartment hatch 18) on one side of the hinge, and the bottom surface 12 of the door 10 (when the door 10 is in the open position) on the other side of the hinge, as illustrated in FIG. 1.

(14) The ladder 22 is preferably collapsible in a telescopic manner as shown in FIG. 6, although other types of collapsible ladders may be used. In one embodiment, the ladder 22 includes a pivoting attachment 26 at one end that is attached to a vertically oriented track 28 within the compartment 20, so that the ladder 22 may slide upwardly and downwardly along the track 28 within the compartment 20. When the ladder 22 is raised from the compartment 20, the pivoting attachment 26 allows the ladder 22 to be folded over the side of the boat, as illustrated in FIGS. 1 and 5. The hatch 18 may include a notch 30, so that the pivoting attachment 26 may extend through the notch 30 while the hatch 18 is in the closed position, which allows for the ladder 22 to be extended into the water while the hatch 18 is closed, as shown in FIG. 1. This arrangement allows the ladder 22 to remain connected to the compartment 20 (and by extension, the boat) both while the ladder 22 is in the extended position, and when the ladder 22 is collapsed and stored within the compartment 20. Optionally, the ladder 22 may be detached from the track 28 within the compartment 20 for repair, maintenance, cleaning or replacement.

(15) The ladder 22 is preferably formed as a single or double telescoping post 32 having a series of steps 34 extending outwardly from the post 32 on either side thereof, as shown in FIGS. 1, 4, 5 and 6. This arrangement allows a user who is wearing fins or flippers to use the steps 34 more easily, because the fin does not have to fit between posts on either side of the step 34. It is contemplated, however, that other types of collapsible ladders may be used, including rope ladders, and telescoping ladders having two longitudinal posts with rungs or steps in-between.

(16) Optionally, a latch, strap or securing mechanism may be used to securely fasten the ladder 22 in the collapsed state within the compartment 20, in order to keep the ladder 22 from rattling or moving excessively while in the stored position, and particularly while the watercraft is underway in choppy or heavy seas.

(17) In one embodiment, the door includes an inner wall that is wider than the outer wall, forming an inner lip 36, as shown in FIG. 2B. This arrangement is particularly advantageous for providing a water-tight seal around the door frame, because a sealing material may be placed around the lip 36 (or door frame), where the lip 36 comes into contact with the door frame or doorway.

(18) Optionally, it is contemplated that the doorway, hatch 18, ladder assembly 22 and compartment 20 may be used without the door, so that there is simply an opening in the hull of the boat, and the compartment hatch 18 opens to reveal the ladder 22 in the collapsed state. The ladder 22 may be extended upwardly from the compartment 20 and dropped over the side of the boat, as described above, and the compartment hatch 18 may then be closed. In this embodiment, the door 10 may be removable, or the assembly may simply be used without a door, so that the doorway is simply a permanent opening in the side of the hull to be used for egress and ingress.

(19) Although the present invention has been described in considerable detail with reference to certain preferred versions thereof, other versions are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred versions contained herein. All features disclosed in this specification may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.
