Abstract
Description
- This invention relates to swim fins, and particularly to individual swim fins that may be readily coupled together when desired to form a monofin, and likewise readily decoupled when the user prefers to have two separate fins.
- The construction of the instant invention allows the two swim fins to be easily attached to and detached from each other at their respective inner edges, and further includes a stopper means that limits the movement of the fins relative to one another as the fins are coupled together.
- Non-limiting embodiments of the present invention will be described by way of example with reference to the accompanying figures, which are schematic and are not intended to be drawn to scale. In the figures, each identical or nearly identical component illustrated is typically represented by a single numeral. For purposes of clarity, not every component is labeled in every figure, nor is every component of each embodiment of the invention shown where illustration is not necessary to allow those of ordinary skill in the art to understand the invention. In the figures:
-
FIG. 1 depicts a pair of swim fins that have been coupled together in accordance with the instant invention. -
FIG. 2 depicts the swim fins as they are being coupled, or decoupled. -
FIG. 3 is a view from the front edge of the fins, showing the coupling mechanism -
FIG. 4 is a close-up view of the coupling mechanism. - One embodiment of the instant invention is shown in
FIG. 1 .Monofin 10 is formed byswim fins fins foot bed 16 having an opening that allows the user to insert his or her foot into each of the fins. - As shown in
FIG. 2 , the instant construction allows thefins FIGS. 3 and 4 ,fin 14 includes a T-shaped projection 20 on its inner edge, which may be fitted into and slid along aslot 24 formed in a C-shaped projection 22 extending along the inside edge offin 12. Astopper 26 at the end of the slot (i.e., the end of the slot away from the foot opening) prevents thefin 14 and itsprojection 20 from sliding any further after theprojection 20 hits the stopper. Stopper 26 (FIG. 1 ) preferably comprises a wall formed at the end of theslot 24. - The T-
shaped projection 20 onfin 14 has a head that slidably mates with theslot 24 inprojection 22, the C-shaped slot overlapping the head ofprojection 20 and preventing movement offin slot 24 andprojection 20. The height ofprojection 22 inFIG. 4 may be 22 mm, theprojection 20 andslot 26 being appropriately proportioned relative thereto - Fins 12 and 14 may be readily decoupled from each other by sliding the
projection 20 out of theslot 24 in the direction away from thestopper 26. - Fins 12 and 14 may be formed or constructed from known materials, such as a blend of polypropylene (42%), thermoplastic rubber (54%), and polyvinyl chloride (4%).
- Those skilled in the art may readily recognize various alterations, modifications, and improvements. Such alterations, modifications, and improvements are intended to be within the scope and spirit of this disclosure. Accordingly, the foregoing description is by way of example only and is not intended to be limiting.
- From the description of at least one embodiment of the present disclosure, various alterations, modifications, and improvements will readily occur to those skilled in the art. Such alterations, modifications, and improvements are intended to be within the scope and spirit of the disclosure. Accordingly, the foregoing description is by way of example only and is not intended to be limiting.
- While several embodiments of the present invention have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the functions and/or obtaining the results and/or one of more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the present invention. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are mean to be exemplary and the actual parameters, dimensions, materials and/or configurations will depend upon the specific application or applications for which the teachings of the present invention is/are used. Those skilled in the art will recognize or be able to ascertain using no more than routine experimentation, many equivalents to the specific embodiments of the invention described herein. It is therefore to be understood that the foregoing embodiments are presented by way of example only and that, with the scope of the appended claims and equivalents thereto, the invention may be practiced otherwise than as specifically described and claimed. The present invention is directed to each individual feature, system, article, material, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, and/or methods, if such features, systems, articles, materials, and/or methods are not mutually inconsistent, is included within the scope of the present invention.
