BACKGROUND OF THE INVENTION
It is frequently desirable for a boat to have a dinghy or similar tender that travels with the boat. A particular example is a sailboat having a keel that may extend four or more feet below the water line of the boat. The presence of the keel means that a dinghy or tender is necessary for passengers and crew to reach land without swimming to land. However, particularly on recreational vehicles, and even those of large size, transporting a dinghy takes up valuable space in or on the boat.
Accordingly, many boats store the dinghy on the transom of the boat. However, devices for attaching a dinghy are cumbersome and expensive, and usually require fixing a mounting bracket or other foundation to the boat. A mounting usually requires drilling undesirable holes into the boat hull, which is usually fiberglass. Further, known devices for mounting a dinghy to the transom of a boat are expensive, frequently costing $1500.00 or more.
There is a need for a transom lift for boats that is inexpensive and easy to use and to which a dinghy can be mounted for transport by the boat without taking up valuable space on the deck of the boat or in a cockpit or cabin of the boat. There is a need for a transom lift that permits the presence of a transom mount ladder.
SUMMARY OF THE INVENTION
The present invention is a transom lift for boats that can be used for transporting a dinghy. The device provides a platform that can also be used for storing and transporting other objects, such as large coolers. Further, the present invention can also be used as a swim platform.
The transom lift according to the invention has generally parallel and vertical members that fit inside of generally vertical and parallel sides of transom mount ladders found on boats, and particularly sail boats. Hooks extend from the generally parallel members, and are constructed and arranged to fit over the steps of the transom mount ladder. A supported planar member or platform extends from a lower portion of the generally vertical spaced apart elongated and parallel members. The transom lift is manually raised and lowered by pulling on an upper end of the transom lift using the transom mount ladder as a guide for vertical movement of the transom lift. Hooks are positioned relative to the steps of the transom mount ladder to position the planar member or platform in the desired vertical position, which may be positioned above or below the water line.

DESCRIPTION OF PREFERRED EMBODIMENTS
FIG. 1 shows the transom lift for boats in isolation and not engaging a transom mount ladder. The transom lift comprises generally vertical, spaced apart, elongated and parallel members 2,4. These members are defined by a left side and a right side that are connected at an upper end. In a preferred embodiment, the upper end is formed as having a generally arcuate shape on a left side and a generally arcuate shape on a right side, with a generally horizontal top portion that forms a handle 16 for assisting vertical movement of the transom lift for boats.
In a preferred embodiment, the left side and the right side of the generally vertical, spaced apart, elongated and parallel members 2,4 are hinged. The hinges 12,14 are preferred to be approximately midway between an upper end of a handle of the generally vertical, spaced apart, elongated, and parallel members and the planar member or platform 6.
Structural supports 28 may be provided between the generally vertical, spaced apart, elongated, and parallel members to provide rigidity for the transom lift. As shown in FIG. 1, two (2) generally horizontal structural supports are provided that join the left side to the right side of the generally vertical, spaced apart, elongated, and parallel members 2,4, with one support present above the hinges 12,14 and one support present at a lower end of the generally vertical, spaced apart, elongated, and parallel members.
As shown in FIG. 2, the transom lift for boats comprises hooks 8,10 that are constructed and arranged for positioning over a step of the transom mount ladder 30. The hooks are preferred to extend generally horizontally from the left side and right side of the generally vertical, spaced apart, elongated, and parallel members 2,4. The hooks may have a generally vertical portion as shown in this embodiment. The generally vertical portion of the hooks is present opposite the left side and the right side of the generally vertical, spaced apart, elongated, and parallel members, and extends vertically downward.
Further, as shown in the drawing figures, the platform 6 extends from the generally vertical, spaced apart, elongated, and parallel members 2,4 and opposite the hooks 8,10. The platform is supported and preferred to be generally planar on a top surface thereof, and is positioned generally horizontally and extending from the generally vertical, spaced apart, elongated, and parallel members.
As shown in FIG. 4, a pair of spaced apart supports 18,20 extend from a lower end of the generally vertical, spaced apart, elongated, and parallel members 2,4 with one of the supports extending from the left side, and one of the supports extended from the right side. The supports extend generally horizontally from the generally vertical, spaced apart, elongated, and parallel members.
The spaced apart supports 18,20 may be joined to a member 22 that extends downwardly from the platform for mounting the platform to the spaced apart supports. The spaced apart supports may engage voids in the member 22 that allow the platform 6 to be removed from the transom lift. Removable pins 32 may be positioned at or near the end of the spaced apart supports that hold the platform in position but allow the platform to be removed as desired.
In a preferred embodiment, the spaced apart supports are hingeably connected to the generally vertical spaced apart elongated and parallel members. Hinges 24,26 allow the platform to be folded upwardly for storage. Similarly, as shown in FIG. 3 and FIG. 4, the upper portion of the generally vertical spaced apart elongated and parallel members may also be folded so that the upper right side becomes generally parallel to the lower right side, and the upper left side becomes generally parallel to the lower left side. These hinges allow storage of the device when not in use since storage is limited on most boats, and particularly sailboats.
FIG. 6 demonstrates the transom mount ladder 30 mounted to the transom 32 of a sailboat 34. The transom mount ladder has a plurality of steps, demonstrated by steps 36,38, 40. As shown in FIG. 6, the transom mount ladder is positioned in an upward and generally vertical position so that the steps are inverted. The transom mount ladder is placed in this position by the ladder being hingeably connected to the transom of the sailboat, as is typical for transom mount ladders on sailboats. The sailboat that is shown has what is known as a reverse transom. That is, the lower portion of the transom extends further out than the upper portion of the transom. Reverse transom sailboats are particularly desirable when the transom lift of the present invention is used, with the angle of the reverse transom aiding lifting and positioning of the transom lift.
FIG. 7 shows a transom lift according to an embodiment of the invention mounted to the transom mount ladder 30 that is in the inverted position shown in FIG. 6 so that the steps are inverted. The hooks 8,10 are positioned over step 40 of the inverted transom mount ladder. The hooks are positioned over the step with the generally horizontal portion of hooks being positioned over the step, with the generally vertical portion of the hook extending over the side of the step of the transom mount ladder that is closest to the transom of the sailboat.
FIG. 8 shows another view of the transom lift positioned on the transom mount ladder 30 and in the position shown in FIG. 7. A dinghy is 42 positioned adjacent to the platform 6 and ready for loading. In this view, the dinghy is floating in water and the platform is positioned below the water line by virtue of the hooks being positioned on the lowest step 40 when the transom mount ladder is positioned in the inverted position. The dinghy is rotated to the vertical position as shown in FIG. 11. The dinghy may be secured by a line tied to the dinghy and the transom lift and other structures of the sailboat. The transom lift is pulled upwardly using the transom mount ladder as a guide as described. The transom lift and dinghy are positioned above the water line for transport.
FIG. 9 demonstrates the transom mount lift having been repositioned to a higher step 38 on the inverted ladder by pulling upwardly on the handle 16 of the transom lift. The pair of generally vertical, spaced apart, elongated, and parallel members 2, 4 are positioned inside of the generally vertical spaced apart and parallel supports of the transom mount swim ladder. Since the pair of generally vertical spaced apart, elongated, and parallel members are between the generally vertical and spaced apart supports 44,46 for the swim ladder, the generally vertical and spaced apart supports of the swim ladder act as a guide or track as the transom lift is manually pulled upwardly from the position of FIG. 8 to the position of FIG. 9. The transom lift may be pulled upwardly by the handle 16, or it may be pulled upwardly using a halyard of the boat or other mechanical device.
The dinghy 42 may be mounted to the platform 6 by rotating the dingy about 90° from the position of FIG. 8 so that a side of the dinghy rests on the platform 6. The transom lift may then be repositioned so that the platform is above the water line as shown in FIG. 9, which is the desired position when the boat or sailboat is underway. FIG. 9 shows the platform as having a large cooler 48 positioned thereon. FIG. 9 shows the upper portion of the generally vertical, spaced apart, elongated and parallel members 2,4 folded to the position shown in FIG. 4.
The transom lift may also be positioned substantially below the water line as shown in FIG. 10. When the transom mount ladder 30 is folded downwardly, the transom lift may be positioned on a step of the transom mount ladder. The transom mount ladder is not inverted. Normally, positioning the platform on the top step 40 when the transom mount ladder is not inverted will place the platform 6 at a sufficient depth for practical use.
