Likewise, unless stated otherwise, use of verbs in the past tense (present perfect or preterit) is not intended to indicate or imply that the invention has been previously reduced to practice or that any testing has been performed.

(14) Referring now specifically to the drawings, a personal standing balance assist assembly according to one exemplary embodiment of the present disclosure is illustrated in FIGS. 1 and 2, and shown generally at broad reference numeral 10. The exemplary balance assist assembly 10 is especially applicable for use in a recreational watercraft, such as a sit-on-top fishing kayak 11, having conventional parts and features including a deck 12, cockpit 14, seat 15, foot wells 16, and hull 18, and a number of molded-in scupper holes 20 or scuppers. Each scupper hole 20 extends vertically from the deck 12 to the hull bottom 18A (See FIG. 7), and ordinarily functions to drain water away from the deck 12 to keep water from accumulating inside the kayak 11 during use. There are typically one to six scupper holes 20 in a kayak spaced apart in and around the cockpit, foot wells and other areas of the deck 12.

(15) Referring to FIGS. 1, 3, and 4-7, the exemplary balance assist assembly 10 comprises a height-adjustable balance assist pole 31, a top scupper plug 32, a bottom hull plug 33 and an elongated assembly connector 35 interconnecting the scupper plug 32 and hull plug 33 at opposite ends of the scupper hole 20. The adjustable balance assist pole 10, described further below, is substantially hollow and includes pole-end inserts 37, 38 at respective proximal and distal ends 31A, 31B, and an ergonomic soft-grip handle 39 at its distal end 31B for being grasped an occupant (not shown) in a standing position on the kayak 11. As best shown in FIG. 7, the pole-end insert 37 has a cylindrical body 37A, an integrally formed tapered fitting 37B, and a central throughbore 37C extending through the body 37A and tapered fitting 37B. The cylindrical body 37A resides inside the balance assist pole 31 at its proximal end 31A, while the tapered fitting 37B extends outwardly from the pole end 31A. In exemplary embodiments, each of the pole-end inserts 37, 38 may be formed of a metal, molded plastic or high durometer rubber. The pole-end inserts 37, 38 may be affixed to the balance assist pole 31 using adhesives or other bonding agents, or by close frictional engagement with inside walls of the pole 31.

(16) The exemplary scupper plug 32 is located adjacent the proximal end 31A of the balance assist pole 31, and comprises an integrally joined two-piece assembly including a molded rigid core 41 and frustoconical outside liner 42. The core 41 defines a relatively large top socket 44 extending to an inside annular shoulder 45 and a smaller diameter, internally threaded throughbore 46 extending from the shoulder 45 to a bottom end of scupper plug 32. The top socket 44 is configured to closely receive the tapered fitting 37B of pole-end insert 37 at the proximal end 31A of the balance assist pole 31. The outside liner 42 covers an entire length of the core 41 and may be affixed to the core using a suitable adhesive, ultrasonic welding or the like. When the assembly 10 is installed, as described further below, the exemplary scupper plug 32 closely engages an interior wall of the scupper hole 20 adjacent a top mouth 20A of the hole. The scupper plug 32 may be uniquely designed to fit kayaks of different manufacturer brands and styles, and may be readily removable and exchangeable. The exemplary outside liner 42 of the scupper plug 32 is fabricated of a hard durable plastic (e.g., ABS) to create a precise no-friction fitavoiding inadvertent lodging of the assembly 10 inside the scupper hole 20 of the kayak 11.

(17) As best shown in FIGS. 1, 3, and 7, the assembly connector 35 comprises an elongated stainless steel assembly bolt 51 having an enlarged cross-slotted or single slotted head 52, and a threaded length 53. The threaded length is sufficient to extend through the scupper hole 20, through aligned throughbores 46 and 37C of scupper plug 32 and pole-end insert 37, and into the hollow proximal end 31A of the balance assist pole 31. The hull plug 33 is carried by the assembly bolt 51 proximate the bolt head 52 and directly adjacent an enlarged annular (rubber) washer 54, and is precisely molded for a close no-friction fit adjacent a bottom mouth 20B of the scupper hole 20. In the exemplary embodiment, the hull plug 33 has an integrally formed disk-shaped top portion 33A and a stepped-down annular flange 33B configured to seat directly against an internal shoulder 20C of the scupper hole 20 proximate the bottom mouth 20B. When the assembly bolt 51 is tightened using a suitable hand tool (e.g., screwdriver, socket driver/wrench), the threaded length 53 operatively mates with the internally threaded throughbore 46 of scupper plug 32, such that the scupper plug 32 and hull plug 33 are urged into close contact with the kayak 11 proximate respective top and bottom mouths 20A, 20B of the scupper hole 20, thereby securing the balance assist assembly 10 to the kayak 11. The exemplary scupper plug 32 and hull plug 33 may be engineered to the exact dimensions of the kayak scupper hole 20 for a perfect no-friction fit at opposing top and bottom mouths of the hole.

(18) Referring to FIGS. 3-5, 7, 8 and 9, the exemplary balance assist pole 31 of assembly 10 comprises telescoping inner and outer hollow tube sections 61, 62, coupling 63, tube cap 63A, and a quick-release circular clamp 64. The tube sections 61, 62 may be fabricated of a rigid material, such as anodized aluminum, carbon fiber, fiberglass, or plastic. The quick-release clamp 64 incorporates a pivoted lever 65 and clamp collar 66. The clamp collar 66 is designed to operatively engage the coupling 63 in a manner which restricts linear sliding movement of the outer tube section 62 relative to the inner tube section 61. As demonstrated in FIGS. 8 and 9, the height of the balance assist pole 31 is adjusted by first opening the pivot lever 65 to release the clamp collar 66see direction arrow 71 in FIG. 8. With the clamp collar 66 released, the occupant of kayak grasps the handle 39 and gently lifts the balance assist pole 31 vertically to slidably telescope the outer tube 62 relative to the inner tube 61, as demonstrated by arrow 72 in FIG. 9. Once the balance assist pole 31 is lengthened to a desired extent, the pivoted lever 65 is returned to its original closed position (see direction arrow 73) locking the clamp collar 66 around the coupling 63 to frictionally set the position of outer tube 62, thereby locating the handle 39 of balance assist pole 31 at a comfortable height for use by the standing occupant. The exemplary balance assist assembly 10 creates an additional point-of-contact to help the kayak occupant maintain balance while standing on the cockpit floor, gunwales, seat platform or other deck surface of the kayak 11. Using the present assembly 10, the lateral load and stresses are uniquely transferred outside of the scupper hole 20 to stronger more durable structure of the kayak deck 12 and hull 18.

These terms are also utilized herein to represent the degree by which a quantitative representation may vary from a stated reference without resulting in a change in the basic function of the subject matter at issue.

(20) Exemplary embodiments of the present invention are described above. No element, act, or instruction used in this description should be construed as important, necessary, critical, or essential to the invention unless explicitly described as such. Although only a few of the exemplary embodiments have been described in detail herein, those skilled in the art will readily appreciate that many modifications are possible in these exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the appended claims.

(21) In the claims, any means-plus-function clauses are intended to cover the structures described herein as performing the recited function and not only structural equivalents, but also equivalent structures. Thus, although a nail and a screw may not be structural equivalents in that a nail employs a cylindrical surface to secure wooden parts together, whereas a screw employs a helical surface, in the environment of fastening wooden parts, a nail and a screw may be equivalent structures. Unless the exact language means for (performing a particular function or step) is recited in the claims, a construction under 35 U.S.C. 112(f) [or 6th paragraph/pre-AIA] is not intended. Additionally, it is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
