BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to aquatic accessories; and more particularly to an aquatic accessory adapted to removably attach to a shoe for providing enhanced swim performance.

2. Related Art

Aquatic sports, and in particular swimming and snorkeling, are highly popular and continue to experience growth each year. Moreover, fins for swim use have become increasingly popular among aquatic enthusiasts.

Fins for swim use generally include a surface area that is larger than that of a human foot. Such fins are useful for providing enhanced swim performance due to an increased propulsive force resulting from the additional surface area. Thus, a user equipped with swim fins generally is capable of swimming faster, and with less effort, than would otherwise be required, allowing the user to swim longer distances while exerting less energy.

Commonly available fins are generally categorized into two forms; i.e. (i) adjustable-strap fins, and (ii) full-foot fins.

Some known adjustable-strap fins have a strap attached at opposite sides. The strap is adjustable for fitting to the foot of an individual user. These fins are worn in place of the user's shoe, thus requiring a user to remove the shoes before installing the fins prior to a swim. Certain problems exist with adjustable fins. For example, straps can loosen in the water or break, and shoes must be left behind or stored away when engaging in aquatic activity. In general, adjustable-strap fins offer minimal comfort since the foot cavity is not sized for an individual user.

Some known full-foot fins include a cavity adapted to approximate the user's foot and generally feature a rigid or semi-rigid heel counter. Problems include, for example, strict fitting requirements necessitating the costly production of a large number of different size fins to accommodate different foot sizes. The actual dimensions of the foot pocket vary widely between brands, making a proper fit difficult. In addition, some known full-foot fins cannot be adjusted for tightness or comfort on the user's foot, and shoes must be left on land or stored away when engaging in aquatic activity with the fins.

Accordingly, these and other problems substantiate a need for improved aquatic accessories.

SUMMARY OF THE INVENTION

In various embodiments, an aquatic accessory includes a receptacle portion adapted to frictionally attach to a user's shoe, and a fin portion extending outwardly from the receptacle portion. In some embodiments, the receptacle portion includes a base extending from an apex to a bottom edge and having an upper surface extending from the apex to an upper edge, the upper surface being connected to the base at a first and second side thereof. The upper edge and bottom edge collectively form a rim. In some embodiments, the fin portion includes a planar fin surface extending outwardly from the base toward a distal lip, the distal lip being disposed opposite of the rim.

In certain embodiments, an inner surface of the receptacle includes one or more gripping members to enhance the frictional attachment of the receptacle portion to the user's shoe. Moreover, frictional retention is further improved with one or more of the gripping members being oriented at an angle toward the apex of the receptacle.

In these and other embodiments, the frictional attachment is further enhanced where the receptacle is fabricated from a stretchable material such that the rim is expandable from a first rest circumference to a second expanded circumference. In this regard, the stretchable receptacle is adapted to provide a radial attachment force for added frictional retention to the shoe of a user.

Other features and benefits of the aquatic accessory are further described in the following detailed descriptions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following description, for purposes of explanation and not limitation, details and descriptions are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments that depart from these details and descriptions without departing from the spirit and scope of the invention as set forth in the appended claims. Certain embodiments will be described below with reference to the drawings wherein illustrative features are denoted by reference numerals such that one having skill in the art may appreciate the features and benefits of the various embodiments of the invention.

In some embodiments, an aquatic accessory is adapted to receive at least a portion of a user's shoe at a receptacle portion and frictionally attach therewith. The aquatic accessory further includes a fin portion extending outwardly from the receptacle portion, the fin portion being adapted to provide enhanced swim performance.

Now turning to the drawings, FIGS. 1-8 illustrate various features of an aquatic accessory in accordance with various embodiments.

FIG. 1A illustrates the aquatic accessory 1a according to an embodiment. The aquatic accessory 1a includes a planar fin portion 4 and a receptacle portion 3 adapted to at least partially receive and affix to a shoe 2 of a user.

FIG. 1B illustrates an aquatic accessory 1b according to another embodiment. The aquatic accessory 1b includes a planar fin portion 4 and a receptacle portion 3 adapted to at least partially receive and affix to a shoe 2 of a user. Moreover, the receptacle portion 3 includes an open toe formed by a hole defined by the apex of the receptacle portion 3. The hole 16 can be of any size and generally permits a toe portion 17 of the user's shoe 2 to at least partially protrude through the hole 16. Additionally, one or more apertures 18 may be disposed on a surface of the planar fin portion 4 for receiving one or more decorative inserts.

FIG. 2 further illustrates the aquatic accessory 1b substantially as depicted in FIG. 1A. The aquatic accessory includes a receptacle portion 3 having a base 7 extending from an apex of the receptacle to a bottom edge 10 and having a length and width associated therewith. The receptacle portion includes an upper surface 5 extending from the apex 15 to an upper edge 9. The upper surface 5 is attached to the base at a first side 6 and a second side 19 (see e.g., FIG. 3) thereof. The upper edge 9 and bottom edge 10 collectively define a rim. In this regard, the base 7 and upper surface 5 are connected to form a cavity defined by an interior portion of the receptacle. The cavity is adapted to receive at least a portion of the user's shoe 2 (not shown in FIG. 2). Moreover, at least a portion of the shoe 2 is frictionally retained by an interior surface of the receptacle. A fin portion 11 is attached to the receptacle and extends outwardly from the apex 15 toward a distal lip. In some embodiments, the fin portion 11 can include a surface area substantially larger than a surface area defined by the length and width of the base 7, and therefore may further be substantially larger than a surface area of the user's foot. Various shapes or designs of the fin portion can be incorporated into the several embodiments depending on manufacturer and user specifications. Thus the shape, design and/or size of the fin portion 4 as depicted is not intended to be limiting in scope.

The frictionally-attached aquatic accessory provides a fast and effective means for attaching a fin device to the shoe of a user. In this regard, the shoe of the user provides a comfortable fit, and the accessory adds the functionality of a swim fin to the shoe. The fin accessory is removable without the requirement of unbuckling or loosening a strap.

In some embodiments, the aquatic accessory can be mated with a shoe fabricated from a water-resistant, lightweight, and flexible material such as, for example, ethylene-vinyl acetate (EVA), polyurethane (PU), polyvinyl chloride (PVC), synthetic rubber, and other similar compositions. The elastic modulus and coefficients of friction of these and similar polymer compositions provide an excellent mechanical basis for friction-attachment with the accessory.

FIG. 3 further illustrates the aquatic accessory according to a bottom perspective view. The aquatic accessory is shown having an optional tread portion 13, the tread portion being adapted for wear on a land surface such as, for example, concrete or asphalt, among others. Although the tread is illustrated, it should be noted that a tread pattern is not a required feature, and that a similar aquatic accessory can be manufactured with no tread without diverting from the spirit and scope of the invention.

Additionally, frictional tabs 8a-b can be provided for (i) assisting a user with shoe insertion and attachment with the accessory, and (ii) frictional retention for maintaining the aquatic accessory in attachment with the user's shoe. In certain embodiments, the tabs can be oriented inward for providing a spring force sufficient to enhance the attachment of the aquatic accessory with the user's shoe. FIGS. 2-4 further illustrate a pair of tabs 8a and 8b, a first tab 8a is attached to the rim 9 of the accessory at the first side 6 and extends outwardly therefrom, and a second tab 8b is attached to the rim 9 of the accessory at the second side 19 and extends outwardly therefrom.

FIG. 4 depicts a rear view of the aquatic accessory according to an embodiment of the invention. The cavity of the aquatic accessory comprises an interior surface 21 having gripping members 14 disposed thereon. The gripping members provide a means for frictionally retaining the portion of the user's shoe being engaged by the interior surface of the accessory.

The gripping members can be grouped into one or more traction groups. In this regard, a plurality of traction groups help to provide added frictional forces for retaining attachment between the accessory and the shoe. FIG. 4 illustrates a first traction group 22 and a second traction group 23, wherein each of the traction groups include one or more gripping members. Any number of traction groups, or gripping members therein, can be provided such that a frictional attachment can be effectuated. However, it should be noted that in many cases two or more traction groups have been shown to increase frictional attachment between the shoe and accessory.

While FIG. 4 illustrates an embodiment having a plurality of gripping members, it should be noted that the gripping members are not necessary in all embodiments. Accordingly, in some embodiments the accessory does not comprise gripping members. In such embodiments the accessory is fiction attached with a relatively large surface area of the cavity being mated surface to surface against an inserted shoe. In addition, the cavity and rim may be increasingly flexible and stretched upon insertion of a shoe such that a retention force created by the cavity against the outer surface of the shoe provides useful gripping or retention.

FIG. 5 is a table illustrating examples of gripping members that may be incorporated into the various embodiments of the invention. It should be noted that although certain examples are provided, the table is not intended to be exhaustive of the numerous shapes and configurations of gripping members for use with the invention. Rather, the illustrative examples depict triangle gripping members, cylindrical gripping members, square gripping members, and angled gripping members. Furthermore, it should be noted that angled gripping members have been shown to enhance frictional retention of a shoe when inserted into the aquatic accessory when the angled gripping members are angled toward the apex of the accessory. Additionally, such angled gripping members if angled toward the rim of the accessory will inhibit insertion of the shoe and may not provide the desired frictional retention. Therefore, angled gripping members should be carefully designed, and preferably angled toward the apex of the receptacle portion for providing the intended frictional retention.

Moreover, FIG. 6 depicts an embodiment of the invention wherein at least a portion of the gripping members 14 are oriented at an angle toward the apex 15 of the receptacle portion. The angled gripping members facilitate the ease of entry of a shoe into the cavity of the accessory, and additionally provide added frictional attachment with an inserted shoe. In this regard, up to all of the gripping members can be angled, or a portion can be angled with the remaining portion being substantially vertical. Similarly, up to all gripping members within a traction group can be similarly oriented at an angle toward the apex. Furthermore, it has been determined that increased frictional attachment is observed with the gripping members being oriented at an angle toward the apex of the receptacle.

FIG. 6 further illustrates the base 7 of the receptacle portion extending from the apex 15 to a bottom edge 10. The upper surface 5 of the receptacle extends from the apex 15 to an upper edge 9. Gripping members 14 can be positioned within an interior surface of the cavity and may be disposed on the inner surface of the upper portion of the receptacle or the inner surface of the base portion of the receptacle. The fin portion 4 extends from the receptacle portion to a distal tip 20.

In accordance with certain other embodiments of the invention, at least a portion of the fin accessory may be fabricated from a stretchable material; i.e. a material having an elastic modulus suitable for retractably stretching from a rest state to an expanded state. Examples of stretchable materials include, for example, polyurethane (PU), thermoplastic polyurethane (TPU), ethylene-vinyl acetate (EVA), rubbers, elastic polymers, and similar materials.

In one embodiment, the rim of the aquatic accessory is adapted to expand from a first rest width and/or circumference to a second expanded width and/or circumference. The accessory having an expanded rim width and/or circumference is referred to as being in an expanded state, wherein the rim width and/or circumference is in the expanded state is greater than that in the rest state. When in an expanded state, the rim is adapted to provide an attachment force directed radially inward, otherwise referred to herein as a “radial gripping force”. The radial gripping force is used to enhance the frictional attachment mechanism for attaching the accessory to an inserted shoe.

In another embodiment, the accessory is adapted to provide a radial gripping force toward an inserted shoe, and gripping members for added frictional attachment of the accessory with an inserted shoe.

In various embodiments described herein, the aquatic accessory is frictionally attached to the shoe of a user; however certain other embodiments further describe a supplemental attachment means for attaching the aquatic accessory to the shoe.

• • For example, the shoe may include one or more apertures and the accessory may include a securing element for inserting into the aperture such that the accessory may be mechanically attached to the shoe of the user. A securing element can be attached to one or more sides or tabs of the accessory and adapted for positioning adjacent to a conjugate aperture of an inserted shoe.

In another embodiment, the accessory may comprise a first slot disposed at a first side of the accessory and a second slot disposed at a second side of the accessory.
