A davit is a crane which projects over the side of a ship and is used especially for lifting boats, anchors, and other such objects. A davit can be a convenience or often a necessity in lifting a dinghy or personal watercraft in and out of a boat. Davits must be designed with sufficient structural integrity to withstand the loads for which they are intended. Typically, then, a davit is at best awkward in appearance. Davits also usually occupy space that could otherwise be used in alternate ways. Most modern boats are extremely concerned with appearance and space utilization. Consequently, typical davits are complex, multi-jointed, hinged devices which attempt to conserve space. What is needed is a basic davit that is not readily apparent to the eye, but can be pivoted and used effectively, then stowed in a manner which does not detract from a boat's appearance or available space. The present apparatus provides these advantages.
The rotating davit apparatus relates to davit systems and more especially to a rotating davit with a one-piece lift arm which blends with a boat arch.
The general purpose of the rotating davit apparatus, described subsequently in greater detail, is to provide a rotating davit apparatus which has many novel features that result in an improved rotating davit apparatus which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.
To attain this, the rotating davit apparatus provides for fit next to an existing boat arch. The apparatus is also provided with a modified arch, as desired by the customer. The apparatus is designed to blend into the shape of boat arches, and is thus provided in a plurality of sizes and lift arm angle variations. The apparatus can be used singularly or in pairs, triplet, or as a quad installation wherein 4 apparatuses are mated to the arch. The apparatus provides utility as well as aesthetic appeal. The basic design provides for relatively inexpensive production and sale.
Thus has been broadly outlined the more important features of the improved rotating davit apparatus so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
An object of the rotating davit apparatus is to provide rotational capability.
Another object of the rotating davit apparatus is to fit congruently with an arch of a boat.
A further object of the rotating davit apparatus is to provide at least 180 degrees of pivot for each apparatus.
An added object of the rotating davit apparatus is to conceal the pulleys and part of the cable of the apparatus.
And, an object of the rotating davit apparatus is to provide an aesthetically pleasing davit which is visually unobtrusive.
Yet another object of the rotating davit apparatus is to be basic.
Another object of the rotating davit apparatus is to be aerodynamic.
These together with additional objects, features and advantages of the improved rotating davit apparatus will be readily apparent to those of ordinary skill in the art upon reading the following detailed description of presently preferred, but nonetheless illustrative, embodiments of the improved rotating davit apparatus when taken in conjunction with the accompanying drawings.
In this respect, before explaining the current embodiments of the improved rotating davit apparatus in detail, it is to be understood that the rotating davit apparatus is not limited in its application to the details of construction and arrangements of the components set forth in the following description or illustration. Those skilled in the art will appreciate that the concept of this disclosure may be readily utilized as a basis for the design of other structures, methods, and systems for carrying out the several purposes of the improved rotating davit apparatus. It is therefore important that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the rotating davit apparatus. It is also to be understood that the phraseology and terminology employed herein are for purposes of description and should not be regarded as limiting.
With reference now to the drawings, and in particular

The apparatus 10 is provided for fit to an existing arch 85, which is modified. The apparatus 10 is also provided with a modified arch 85B included. The apparatus 10 provides for proper aerodynamics, whether fitted in singular or multiple apparatus 10 use.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the rotating davit apparatus, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the rotating davit apparatus.
Directional terms such as “front”, “back”, “in”, “out”, “downward”, “upper”, “lower”, and the like may have been used in the description. These terms are applicable to the embodiments shown and described in conjunction with the drawings. These terms are merely used for the purpose of description in connection with the drawings and do not necessarily apply to the position in which the rotating davit apparatus may be used.
Therefore, the foregoing is considered as illustrative only of the principles of the rotating davit apparatus. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the rotating davit apparatus to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the rotating davit apparatus.
