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.
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.
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.

Now turning to the drawings,
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.
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.
