DETAILED DESCRIPTION OF ASPECTS OF SOME EXAMPLE EMBODIMENTS

As noted above, embodiments within the scope of the present invention generally relate to boards, such as paddleboards, suitable for use in water sports or other activities. One or more aspects of example embodiments may also find application in equipment such as, but not limited to, surfboards, paipo boards, boards for wind surfers, knee boards, wakeboards, and body boards, examples of which include boards referred to as boogie boards.
With attention first to FIG. 1, an upper perspective view of an example paddleboard 100 is disclosed. The paddleboard 100 may be approximately 10 feet long, although other embodiments may be longer, or shorter. The disclosed example of a paddleboard 100 includes a body 102 having a front 102 a and a back 102 b. In at least some embodiments (and as best shown in FIG. 5), the front 102 a may be turned up, and the back 102 b may have a fish tail configuration. Near the front 102 a, a recess 104 may be defined that provides space for a user to grasp a handle 106 attached to the body 102. The handle 106 can be attached, permanently or removably, to the body 102 in any suitable way. In at least one embodiment, the handle 106 is attached to the body 102 with one or more fasteners 108, such as rivets, pins or screws for example. Embodiments of the paddleboard 100 may include more than one handle 106, and the handle 106 may be plastic, metal or other material. The paddleboard 100 may include one or more plugs 110 that are configured to removably engage the body 102. The plugs 110 may be plastic, rubber, metal, or other material, and may enable a user to drain any water that may have collected within the body 102, and the plugs 110 may include threads configured to engage corresponding threads of the body 102. Some embodiments of the paddleboard 100 may include one or more plugs 112 that include a loop 112 a to which a shock cord, rope, or other element can be attached. As discussed in further detail below, the paddleboard 100 may include one or more fins 200. Finally, at least some embodiments of the paddleboard 100 may include deck covering 114 disposed on at least a portion of the paddleboard 100. In some embodiments, the deck covering 114 comprises ethylene-vinyl acetate material. The deck covering 114 may constitute, or include, a non-slip material or configuration that may enable a user to better grip the paddleboard 100.
With continued reference to FIG. 1, and directing particular attention to the body 102, embodiments of the paddleboard 100 may include a body 102 that is at least partly hollow. In some embodiments, the body 102 is substantially hollow. The body 102 may be formed as part of a unitary, one-piece structure during a blow-molding process and may include one or more tack-offs. Additionally, or alternatively, roto-molding, twin-sheet, and/or other processes may also be employed to produce part or all of the body 102.
The body 102 may include an upper surface 102 c and a lower surface 102 d. As noted earlier, a portion of the upper surface 102 c may be covered with a deck covering 114. The upper surface 102 c and/or lower surface 102 d may incorporate a surface treatment and/or be textured in any desired manner. The texturing can be performed with the use of chemical etching or other processes. The type of texturing, which may be rough, smooth, or some other type, employed may vary from one part of the upper/lower surface 102 c/102 d to another. For example, texturing in the area of the upper surface 102 c where a user is likely to stand, or to grip the paddleboard 100, may be relatively rough so as to enhance the grip of the user.
As shown in the example of FIG. 1, at least a portion of the upper surface 102 c may be recessed such that it lies below a pair of side rails 102 e running along the sides of the paddleboard 100. In other embodiments, the upper surface 102 c is not recessed. The side rails 102 e may curve or slope away from the upper surface 102 c, and their position above the recessed upper surface 102 c may lend rigidity to the paddleboard 100. In the example of FIG. 1, a rib 102 f is provided that runs longitudinally along at least a portion of the length of the paddleboard 100. In terms of its orientation, the rib 102 f may be located proximate, or on, a centerline AA of the paddleboard 100. In the example of FIG. 1, the rib 102 f extends from a location proximate the handle 106 to a location proximate the start of the fish tail configuration, although ribs of longer, or shorter, length may be employed. In some instances, the rib 102 f may be employed by a user to store a paddle or other equipment.
The rib 102 f may be concave, and variables such as the length, width and depth of the rib 102 f can be varied. The rib 102 f may constitute, or include, one or more tack-offs that extend from the upper surface 102 c into the interior (not shown) of the body 102. At least some embodiments of the paddleboard include multiple ribs in the upper surface. The ribs may be substantially the same as each other, or may be different from each other. For example, some ribs may be longer than others, and/or some ribs may be deeper and/or wider than others. In at least one embodiment, the rib 102 f may include one or more scuppers (not shown) which allow water to drain from the paddleboard 100. By way of example, the scupper(s) may comprise a tack-off that has been drilled out, or that has been punched out as part of a molding process.
Among other things, the use of one or more ribs 102 f in the upper surface 102 c may lend strength and rigidity to the paddleboard 100, while also reducing its weight. The strength and rigidity of the paddleboard 100 may be especially enhanced where the rib(s) 102 f constitute, or comprise, one or more tack-offs that extend into the interior of the body 102 toward the lower surface 102 d. In some embodiments, one or more of such tack-offs may contact the interior of the lower surface 102 d while, in other embodiments, one or more of the tack-offs may extend toward, but terminate short of, the interior of the lower surface 102 d. As suggested elsewhere herein, where the rib 102 f comprises a plurality of tack-offs, all of the tack-offs may terminate short of the interior of the lower surface 102 d, or one or more tack-offs may terminate short of the interior of the lower surface 102 d while one or more other tack-offs contact the interior of the lower surface 102, or all of the tack-offs may contact the interior of the lower surface 102 d.
As further indicated in FIG. 1, at least some embodiments of the paddleboard 100 may include one or more recesses 102 g that may be configured and arranged to facilitate gripping, carrying, and/or maneuvering of the paddleboard 100 by a user. For example, the recess(es) 102 g positioned in the rib 102 f may provide a handhold for a user who desires to carry the paddleboard 100 under his arm. Additionally, or alternatively, one or more such handholds can be located in the bottom of the paddleboard 100, such as in the groove(s) 102 k (see FIG. 6), for example.
Directing attention now to FIG. 2, and with continued attention to FIG. 1, some embodiments of the paddleboard 10 may include one or more pad eyes 116 connected to the body 102. The pad eyes 116 may enable a user to removably connect retention elements 118 such as shock cords, ropes, or other devices to the body 102. In the example of FIG. 2, the paddleboard further includes fins 200 that may include loops to which a retention element 118, such as shock cord, rope or other device can be attached. In this way, a user can use the back 102 b of the paddleboard 100 to securely store various items. Although the pad eyes 116 in the example of FIG. 2 are located at the back 102 b of the paddleboard 100, other locations may additionally or alternatively be employed.
With attention now to FIGS. 3 and 4, additional details are provided concerning the example paddleboard 100, shown with the deck covering 114 removed. As indicated in FIG. 3, the upper surface 102 c may include one or more depressions 102 h, one or more of which may be partly, or completely, filled with a filler material 102 i that may be buoyant and comprise expanded polystyrene foam, although other buoyant filler materials may be employed. In the example of FIGS. 3 and 4, four depressions 102 h are provided, although more or fewer depressions can be employed. As well, the configuration, size, location and orientation of the depressions 102 h are presented solely by way of example, and depressions of other sizes, configurations, locations and/or orientations can be employed. One or more of the depressions 102 h may extend partway into the interior of the body 102 toward, but terminating short of, the interior of lower surface 102 d, one or more of the depressions 102 h may extend toward, and contact, the interior of the lower surface 102 d, and some embodiments may include depressions 102 h of both of these configurations.
Among other things, the depressions 102 h may contribute to the strength and rigidity of the paddleboard 100. The buoyant filler material 102 i may improve the overall buoyancy of the paddleboard 100.
With particular reference now to FIGS. 4 and 5, further details are provided concerning attachment of the fins 200 to the body 102 of the paddleboard 100. As indicated in FIG. 4, the body 102 defines a pair of fin housings 102 j in which a corresponding fin 200 is configured to be at least partly received. While two fins 200 are indicated in the example of FIGS. 4 and 5, more, or fewer, fins 200 may be employed in other embodiments. Where more than one fin housing 102 j is provided, one or more fin housings 102 j may include a removable cover in the event that fewer than all the fin housings 102 j are employed. In this way, a user can customize the set-up of the paddleboard 100 by using fewer fins 200 than the maximum that the paddleboard 100 is configured to use. Likewise, the user can customize the placement of the fins 200 in a desired configuration, and can further customize the set-up of the paddleboard 100 by mixing different types of fins in a particular configuration, or by removing one set of fins and replacing those fins with fins having a different physical size and/or configuration.
In order to connect and releasably retain the fins 200 to the body 102, respective fin retention elements 120 are provided. The fin retention elements 120 are configured such that when the upper portion of each fin 200 is inserted into a corresponding fin housing 102 j, the fin retention element 120 can then be secured to the fin 200 and/or the body 102, thereby securing the fin 200 to the body 102. The fin retention elements 120 and the body 102 may include structures configured to releasably engage complementary structure of the fins 200 so that the fins 200 can be removably attached to the body 102. For example, the fin retention elements 120 may be configured to be removably snap-fit into place in the fin housing 102 j and/or onto the fin 200. As another example, the fin retention elements 120 may include threads configured to releasably engage corresponding threads of the fin 200.
As the foregoing makes clear, the fin retention elements 120 are example structural implementations of a means for releasably retaining a fin 200 in one or more positions. Any other structure(s) of comparable functionality may alternatively be employed.
The fin retention elements 120 are configured, in at least some embodiments, to permit adjustments to the position of the fins 200. For example, by loosening and/or removing a fin retention element 120 from a fin 200 and/or the body 102, the rotational position of the fin 200 can then be adjusted. Detents, slots and/or other structures may be provided in the fin housings 102 j, the fin 200, and/or the fin retention elements 120, to enable the fin 200 to be secured to the body 102 in any of a variety of different positions. Such detents, slots and/or other structures may also enable the fin 200 to move through a defined range of motion. In at least some embodiments, the fins 200 may be oriented in the same direction as each other so as to be substantially parallel when residing in a first operating position and, further, the fins 200 may be oriented in different directions from each other so as to be angled toward, or away from, each other when residing in a second operating position. Yet other fin 200 positions may also be defined and employed.
Among other things, the ability to change the orientation of one or more of the fins 200 may allow the user to customize the set-up of the paddleboard to assume various configurations to suit a contemplated use. More particularly, when the fins 200 are angled toward each other in the second operating position, the paddleboard 100 may be in a paddling configuration where such a position of the fins 200 may facilitate tracking of the paddleboard 100 when a user is paddling the paddleboard 100. When the fins 200 are substantially parallel to each other in the first operating position (as best shown in FIG. 6), the paddleboard 100 may be in a surfing configuration where such a position of the fins 200 may facilitate steering control when a user is surfing with the paddleboard 100.
Stated more generally, and as noted earlier, the paddleboard 100 is configured to enable a user to change the set-up of the board, by adjusting one or more of the position, type, and number of the fins, to assume various configurations for different contemplated uses. This attribute of the paddleboard 100 also enables a user to switch out the fins 200 for different types and/or sizes of fins, depending upon the contemplated use of the paddleboard 100. Thus, the fins and fin retention elements collectively comprise an example structural implementation of a means for reconfiguring the board to assume different operating configurations. Any other structure(s) of comparable functionality may likewise be employed.
Turning now to FIGS. 6 and 7, further details are provided concerning aspects of the lower surface 102 d of the example paddleboard 100. In general, and with general reference to FIG. 6, embodiments of the invention may include one, two, three, or more grooves 102 k in a lower surface 102 d of the paddleboard 100. One or more of the grooves 102 k may have the same, or different, configuration, size, and/or orientation, than one or more other grooves 102 k, and the scope of the invention is not limited to any particular number, configuration, size, or orientation of grooves 102 k. As exemplified in FIG. 6, one groove may be longer than another. As well, at least one of the grooves 102 k may be substantially parallel to at least one other groove 102 k. Further, one or more grooves 102 k may be located proximate, or on, the centerline AA of the paddleboard 100. At least one groove 102 k may extend along a substantial portion of the length of the paddleboard 100. As well, at least one groove 102 k may constitute, or comprise, one or more tack-offs. As such, at least a portion of at least one groove 102 k may extend into an interior of the paddleboard 100 toward an interior portion of, for example, the upper surface 102 c (see FIG. 1). Such portion of the groove 102 k may, or may not, actually contact the interior portion of the upper surface 102 c (see FIG. 1).
Referring now to the particular example of FIG. 6, two outer grooves 102 k and one inner groove 102 k are provided. As shown, the outer grooves 102 k are similar to each other in their configuration, size, and orientation, although in other embodiments, the outer grooves, if employed, may be dissimilar to each other in one or more of these aspects. Disposed between the two outer grooves 102 k is an inner groove 102 k that is shorter than the outer grooves 102 k. In the example of FIG. 6, all of the grooves 102 k terminate in approximately the same location near the back 102 b of the paddleboard 100, while the two outer grooves 102 k extend further toward the front 102 a than does the inner groove 102 k. Further, and as indicated in FIG. 6, the outer grooves 102 k may curve inwardly towards each other near the front 102 a of the paddleboard 100, and one, some, or all of the grooves 102 k may have a depth that varies from one part of a groove to another part.
Finally, one or more of the grooves 102 k may include one or more tack-offs 103. One or more of the tack-offs 103 may extend into the interior of the paddleboard 100 and contact a surface in the interior of the paddleboard 100 and/or terminate short of a surface in the interior of the paddleboard 100. In the example of FIG. 6, six tack-offs 103 are indicated, although more, or fewer, tack-offs 103 may be employed.
Among other things, one or more grooves 102 k may serve to enhance the strength and rigidity of the paddleboard 100, particularly in a longitudinal direction generally parallel to the centerline AA, while also facilitating tracking and maneuverability of the paddleboard 100 in use.
With particular attention now to FIG. 8, and renewed attention to FIG. 7, details are provided concerning an example fin 200 such as may be employed in at least some example embodiments. As noted earlier herein, the paddleboard 100 may include one or more fin housings 102 j, each of which is configured to removably receive a corresponding fin. As best shown in FIG. 7, the lower surface 102 d may include a recessed portion 102 d−1 in which a corresponding portion of the fin 200, discussed below, can be seated. The size and/or configuration of the recessed portion 102 d−1 can be varied to define a plurality of different fin 200 positions.
As indicated in FIG. 8, the example fin 200 includes a fin portion 202 configured to extend below the bottom of the paddleboard 100. Atop the fin portion 202 is a seat portion 204 configured to be removably received, or seated, in the recessed portion 102 d−1, as shown in FIG. 7. A shoulder 205 may be provided that interacts with corresponding structure of the paddleboard 100, such as a plurality of notches (not shown) to enable the fin 200 to be secured in a plurality of different orientations relative to the paddleboard 100. A fin post 206 of the fin 200 is configured to extend into the fin housing 102 j of the paddleboard 100 when the seat portion 204 is received in the recessed portion 102 d−1. One or more stabilizer elements 208 may be attached to the fin post 206 and are configured to contact the interior of the fin housing 102 j when the fin 200 is positioned in the fin housing 102 j. Among other things, the stabilizer elements 208 may help to minimize, or eliminate, lateral movement of the fin post 206 in the fin housing 102 j, and thereby enhance the performance of the fin 200 and the paddleboard 100.
With continued reference to FIG. 8, the fin 200 includes a threaded portion 210 that is configured to releasably engage a correspondingly threaded fin retention element 120 (see FIGS. 2 and 4). As a result of this configuration and arrangement of the fin 200 and fin retention element 120, a user can readily loosen the fin 200 so as to be able adjust the rotational position of the fin 200 and point the fin 200 in a desired direction. Subsequent to such an adjustment, the fin 200 can be secured in the desired position by tightening the fin retention element 120 onto the fin 200. As well, the configuration and arrangement of the fin 200 and fin retention element 120 enable a user to remove and/or replace the fin 200 if desired. With reference to both FIG. 8 and FIG. 3, the example fin 200 includes a cap portion 212 that cooperates with the fin retention element 120 to substantially close off the fin housing 102 j when the fin 200 is fully received within the fin housing 102 j. Finally, the example fin 200 includes one or more retention slots 214, or comparable structures, in the upper portion of the fin 200. As indicated in FIG. 2, the retention slots 214 may enable temporary attachment of a retention element 118 to the top of the fin 200.
Embodiments of the fin 200 may comprise any suitable material, including plastic, metal, rubber, carbon or carbon fiber materials, composites, and combinations of any of the foregoing. Some embodiments of the fin 200 comprise a single piece of material, while other embodiments of the fin 200 comprise various portions assembled together to form the final configuration. The geometry of the fin portion 202 shown in the figures is presented by way of example only. In fact, a wide variety of other fin portion 202 geometries may be employed depending upon variables such as the intended use of the fin 200, and the conditions in which the fin 200 is to be employed. For example, a generally triangular fin portion geometry may be useful in some applications. As noted herein, one or more of the fins 200 can be readily removed and replaced with another fin having a fin portion with a different geometry. Moreover, in some instances, fewer than all of the fin housings 102 j may be occupied by a fin.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
