SHEET 3 [1F 3 H9010 Inventor Lloyd H. Busby COMBINATION LADDER AND HOIST APPARATUS BACKGROUND OF THE INVENTION 1. Field of the Invention:
The present invention relates to a device for Stowing a dinghy from a large boat.
2. Description of the Prior Art:
Numerous brackets have been proposed for being mounted from the transom of a large boat for stowing a dinghy. Many of these prior art brackets include clamps for clamping to the side of a dinghy so the opposite side of such dinghy may be pivoted upwardly to support the dinghy from such clamps. Stowing devices of this type are shown in U.S. Pat. Nos. 3,422,241, 3,2l6,388 and 3,143,991. Stowing devices of this type are impractical to mount from the transom of many boats and are inconvenient to use since nearly perfect alignment is required between the clamps and the dinghy rail.
SUMMARY OF THE INVENTION 'The combination ladder and hoist apparatus of present invention is characterized by a ladder having means on its upper extremity for being mounted from a transom of a large boat. Hook means if formed on the lower extremity of the ladder for hooking to the rail formed by the upper extremity of a gunwale on one side of a dinghy to be stowed. An abutment post projects from the upper extremity of the ladder for abutting the side of the dinghy opposite the one side and hoisting means is provided for securing the dinghy in position on the hook means and abutting the abutment means. Consequently, the dinghy may conveniently be floated athwartship adjacent the transom and the rail hooked on the hook means. The opposite side of the dinghy may then be raised into position abutting the abutment means to thereby stow the dinghy in supporting position on the hook means and abutted against the abutment means.

DESCRIPTION OF THE PREFERRED I EMBODIMENTS Referring to FIG. 1, the combination ladder and hoist apparatus of present invention includes a ladder, generally designated 21, which is formed on its upper extremity with a pair of forwardly projecting mounting arms 23 and 25 and on its lower extremity with rearwardly projecting hooks 27 and 29. Mounted on the upper extremity of the ladder 21 are a pair of rearwardly projecting abutment posts 31 and 33. Consequently, a dinghy, generally designated 35, may be brought adjacent the combination ladder and hoist apparatus as shown in FIG. 1, and one side thereof hooked on the hooks 27 and 29 and the opposite side thereof hoisted to pivot such dinghy about the hooks 27 and 29 to the position shown in FIG. 10 to engage the bottom wall of the dinghy with the abutment posts 31 and 33 to maintain such dinghy stowed on its side as shown in FIG. 10. I
Referring to FIG. 1, relatively large pleasure boats, generally designated 37, are frequently formed on their stern with a vertically extending transom 39 which terminates at its upper edge with a flat horizontal surface 41. The combination ladder and hoist apparatus 21 includes a pair of vertically extending side members 45 and 47 which are bent to project forwardly on their upper extremity to form the mounting arms 23 and 25.
A pair of hanger cleats 51 and 53 are mounted on the top edge 41 of the transom 49 and include inverted U- shaped bales 55 and 57 for receipt of the mounting arms 23 and 25. The mounting arms 23 and 25 are formed on their forward extremity with upturned retaining flanges 61 and 63 which are projected through the bales 55 and 57 and engage therebehind.
Connected between the lower portions of the vertical members 45 and 47 is a horizontally extending step in the form of an angle iron 67.
The abutment posts 31 and 33 are in the form of rearwardly projecting rods which are threaded on their forward extremities and screwed into internally threaded bores formed in the vertical side members 45 and 47 as shown in FIG. 8. The rear extremities of such abutment posts have cushioning pads 71 and 73, respectively, inserted thereover for protecting the bottom of the dinghy 35 against damage.
Referring to FIG. 4, the hooks 27 and 29 are formed with respective through bores which may have lines 72 threaded therethrough and knotted as shown in FIGS. 9 and 10.
Referring to FIGS. 1 and 9, dinghies 35 are frequently formed with vertically projecting side walls which form gunwales 74 that are turned outwardly on their upper extremities to define outwardly projecting flanges in the form of peripheral rails 76.
In operation, the combination ladder and hoist apparatus may be mounted from the boat 37 by securing the mounting brackets 51 and 53 to the upper edge of the transom 39 by means of screws 78 (FIG. 3). The combination ladder and hoist apparatus may then be conveniently mounted to the transom 39 by merely rotating such apparatus to a somewhat horizontal position and inserting the retaining flanges 61 and 63 through the respective bales 55 and 57 and then rotating the lower extremity of such ladder downwardly to orient the ladder vertically at the rear of the transom 39 as shown in FIG. 1. The ladder apparatus will then be held securely in position and ready for use.
When it is desirable to stow the dinghy 35 from boat 37, the operator thereof may paddle such dinghy adjacent the transom 39 as shown in FIG. 1 and rock the one side thereof upwardly to hook the rail 76 over the hooks 27 and 29 as shown in FIG. 9. The operator may then grasp upper edge 41 of the transom 39 and place a foot on the step 67 and climb from the dinghy 35 while leaving the rail 76 hooked on such hooks 27 and 29.
respective lines may then be secured to cleats to hold the dinghy in its stowed position.
Referring to FIGS. 5 and 6, the combination ladder and hoist apparatus shown therein is substantially the same as that shown in FIG. 1 except that the mounting arms 23 and 25 are formed with through bores 85 and 87, respectively, for receipt of respective upwardly projecting studs 91 and 93 included in respective mounting brackets 95 and 97 mounted on the upper edge 41 of the transom '39.
The side members 45 and 47 are formed with a pair of respective prongs 101 and 103 which project downwardly beyond the hooks 27 and 29 and are telescopically received in respective bales 105 and 107 of respective mounting brackets 111 and 113 secured to the outboard side of the transom 39. Consequently, the combination ladder and hoist apparatus shown in FIG. 5 is secured firmly to the transom 39 at both its upper and lower extremities.
From the foregoing it will be apparent that the combination ladder and hoist apparatus provides a convenient and inexpensive means for stowing a dinghy from a large boat and also provides a ladder for egress from such dinghy to the large boat.
