Description
TITLE : SAIL OR SURF BOARD TO KAYAK CONVERSION KIT
FIELD OF THE INVENTION
The present invention relates to an accessory arrangement for converting a water buoyant board such as a sail board or surf board into a kayak type paddling craft.
BACKGROUND OF THE INVENTION
Water sports are becoming increasingly popular. Costs and physical size constraints can prevent the use of kayaks in a large number of cases and use of surf and sail boards is often prevented due to lack of wind or waves.
A conversion kit to convert a sail or surf board into a water bicycle is described in U.S. patent 4,511,338 dated April 16, 1985 entitled "Water bicycle and detachable device therefor", inventor Noel Fanelli.
Another conversion kit is described in U.S. patent 5,377,607 dated January 3, 1995 entitled "Conversion arrangement for sail board with seat", inventor Gerald S. Ross.
Still another conversion kit is described in U.S. patent 4,752,261 dated June 21, 1988 entitled "Auxiliary seat for surf boards", inventor Michael A. Rosello Zoya.
The Fanelli patent describes the use of board encircling straps to secure the conversion kit to the board but otherwise has no relation to a kayak type paddling craft. The Ross patent shows in figure 3 the board used as a kayak, however the seat is adjustable but not the foot rest, therefor the seat cannot be conveniently positioned in the region of the buoyant center of the board irrespective of the user's height.
The Zoya patent shows an arrangement in which the distance between the foot rest and seat can be adjusted to suit the height of the user but the kit frame rests flat on the surf board and therefore could not conveniently clear feet anchoring straps and mast anchors normally portruding form the top wall of a sail board. Also, adjustment of the distance between the foot rest and seat is difficult to achieve.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figure 1 shows a conventional sail board A, with a top wall B, a bow C and a stern D.
5 The conversion kit or accessory arrangement in accordance with the present invention, when installed on board, enables a user U to ride the resulting craft as a kayak type paddling craft, using a hand held double paddle oar O while facing toward bow C.
The conversion kit of the invention comprises a chassis 4 of generally rectangular shape and composed of longitudinal rails 8 and front and back cross-members 10 rigidly interconnecting the rails 8. As shown in figure 5, a flat bar 12 is secured by bolts 14, underneath each cross-member 10, and suction cups 16 are secured to the ends of each flat bar 12 to adhere to the top wall B of sail board A; board encircling straps 18 are secured at their ends to strap anchor bolts 20 secured to the cross-members 10 and underlying flat bars 12. Each strap 18 is provided with strap tighteners 22 of conventional construction. By tightening the straps, the suction cups are flattened against the board and yet the chassis 8, 10 is fumly held in upwardly spaced relationship with the top wall B so that it will clear any portruding parts of the sail board such as its foot anchoring straps and mast anchors.
In an alternative arrangement as shown in figure 6, the board encircling straps 18 are replaced by another anchoring system including screw inserts 24 permanently positioned within the top wall B and screws 26 carried by the cross-members 10 and flat bars 12 and conveniently screwed within screw inserts 24. After removal of the chassis, screw inserts 24 are closed by conventional plugs.
A molded seat 28 is permanently secured to the rear end portion 30 of each rail 8, the seat extending across board A; front end portions 32 of both rails 8 support a foot rest 34 of inverted V shape cross-section which includes a feet abutting wall 36 which faces rearwardly of the craft and is downwardly rearwardly inclined. Foot rest 34 further includes a pair of slide members 38 of channel shape fitting over the channel shaped rails 8 of the chassis 4 The slide members 38 are provided with a hole 40 adapted to come in selecting register with anyone of several locating holes 42 made in the rails 8 for insertion of a locking pin 41 (figure 11 ). Therefore, the foot rest can be longitudinally adjusted and locked in adjusted position.
It is obvious that the chassis 8,10 can be adjustably secured on the board A
longitudinally of the latter so as to position the seat 28 in the region of the buoyant center of the board A to obtain a minimum of water resistance when the user U is paddling. The foot rest can then be adjusted along rails 8 for maximum paddling efficiency and comfort of the user in accordance with his height.
The feet abutting surface 36 has a sufficient area to receive user's feet in side by side position and is conveniently downwardly rearwardly inclined so that the user's feet can exert a maximum pressure on the same when the user is paddling.
Since surf board A is quite narrow, and user U sits higher on the same, oar O, when paddling, easily clears the sides of the sail board A.
The accessory arrangement 4 can be optionally fitted with a rudder system which includes an over stern rudder 44 (see figures 7 to 12) which is secured at 45 to a rudder bracket 46 fitted with a pivot rod 48 pivotally mounted on a mounting plate 50 to be secured to the stern D by suitable fasteners. A double arm 52 is secured to the top of the pivot rod 48 and carries studs 54 which are equally spaced from rod 48. Foot rest 34 has a front protuberance 56 forming a journal for a control rod 58 to the lower end of which is secured a double arm control 60. A pair of steering cables 68 running longitudinally of the board and under rails 8, are attached at their ends to the outer ends of the two double arms 52 and 60.
A control stick 70 is secured to the top end of control rod 58 by means of its flanged split sleeve 72 and with the interposition of a washer 74. Control stick 70 has an enlarged free end portion 76 which extends between the user's feet so as to be pushed right or left by the same; control stick 70 freely extends within a top notch 78 of foot rest 34.
The e$'ective length of each cable 68 can be adjusted; for instance each cable 68 is terminated by a chain 80, any chain link of which can be selectively fitted over a stud 54 of rudder double arms 52. Therefor cables 68 are maintained taut between double arm 52 and 60 irrespective of the longitudinally adjusted position of foot rest 34.
It is therefore the main object of the present invention to provide a conversion kit of the character described which obviates the above noted disadvantages, more particularly in which the foot rest is adjustable with respect to the seat for maximum comfort and performance.
Another object of the invention is to provide a conversion kit of the character described in which the foot rest and seat are mounted on a chassis which is spaced above the top wall of the board so as to clear the feet anchoring straps and the mast anchor normally found on a sail board.
Another object of the present invention is to provide a conversion kit of the character described incorporating a steering assembly including a foot rest mounted control stick accessible to the user's feet and connected to the stern mounted rudder via adjustable cables, maintained taut despite the variable distance between the adjustable foot rest and the seat.
Another object of the invention is to provide a converted craft which, depending on the type of basic board being used, emulates closely the performance of river flat water racing and recreational kayaks and surf ski and wave ski kayaks and as such may be used for training and recreational purposes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figure 1 shows a conventional sail board A, with a top wall B, a bow C and a stern D.
5 The conversion kit or accessory arrangement in accordance with the present invention, when installed on board, enables a user U to ride the resulting craft as a kayak type paddling craft, using a hand held double paddle oar O while facing toward bow C.
The conversion kit of the invention comprises a chassis 4 of generally rectangular shape and composed of longitudinal rails 8 and front and back cross-members 10 rigidly interconnecting the rails 8. As shown in figure 5, a flat bar 12 is secured by bolts 14, underneath each cross-member 10, and suction cups 16 are secured to the ends of each flat bar 12 to adhere to the top wall B of sail board A; board encircling straps 18 are secured at their ends to strap anchor bolts 20 secured to the cross-members 10 and underlying flat bars 12. Each strap 18 is provided with strap tighteners 22 of conventional construction. By tightening the straps, the suction cups are flattened against the board and yet the chassis 8, 10 is fumly held in upwardly spaced relationship with the top wall B so that it will clear any portruding parts of the sail board such as its foot anchoring straps and mast anchors.
In an alternative arrangement as shown in figure 6, the board encircling straps 18 are replaced by another anchoring system including screw inserts 24 permanently positioned within the top wall B and screws 26 carried by the cross-members 10 and flat bars 12 and conveniently screwed within screw inserts 24. After removal of the chassis, screw inserts 24 are closed by conventional plugs.
A molded seat 28 is permanently secured to the rear end portion 30 of each rail 8, the seat extending across board A; front end portions 32 of both rails 8 support a foot rest 34 of inverted V shape cross-section which includes a feet abutting wall 36 which faces rearwardly of the craft and is downwardly rearwardly inclined. Foot rest 34 further includes a pair of slide members 38 of channel shape fitting over the channel shaped rails 8 of the chassis 4 The slide members 38 are provided with a hole 40 adapted to come in selecting register with anyone of several locating holes 42 made in the rails 8 for insertion of a locking pin 41 (figure 11 ). Therefore, the foot rest can be longitudinally adjusted and locked in adjusted position.
It is obvious that the chassis 8,10 can be adjustably secured on the board A
longitudinally of the latter so as to position the seat 28 in the region of the buoyant center of the board A to obtain a minimum of water resistance when the user U is paddling. The foot rest can then be adjusted along rails 8 for maximum paddling efficiency and comfort of the user in accordance with his height.
The feet abutting surface 36 has a sufficient area to receive user's feet in side by side position and is conveniently downwardly rearwardly inclined so that the user's feet can exert a maximum pressure on the same when the user is paddling.
Since surf board A is quite narrow, and user U sits higher on the same, oar O, when paddling, easily clears the sides of the sail board A.
The accessory arrangement 4 can be optionally fitted with a rudder system which includes an over stern rudder 44 (see figures 7 to 12) which is secured at 45 to a rudder bracket 46 fitted with a pivot rod 48 pivotally mounted on a mounting plate 50 to be secured to the stern D by suitable fasteners. A double arm 52 is secured to the top of the pivot rod 48 and carries studs 54 which are equally spaced from rod 48. Foot rest 34 has a front protuberance 56 forming a journal for a control rod 58 to the lower end of which is secured a double arm control 60. A pair of steering cables 68 running longitudinally of the board and under rails 8, are attached at their ends to the outer ends of the two double arms 52 and 60.
A control stick 70 is secured to the top end of control rod 58 by means of its flanged split sleeve 72 and with the interposition of a washer 74. Control stick 70 has an enlarged free end portion 76 which extends between the user's feet so as to be pushed right or left by the same; control stick 70 freely extends within a top notch 78 of foot rest 34.
The e$'ective length of each cable 68 can be adjusted; for instance each cable 68 is terminated by a chain 80, any chain link of which can be selectively fitted over a stud 54 of rudder double arms 52. Therefor cables 68 are maintained taut between double arm 52 and 60 irrespective of the longitudinally adjusted position of foot rest 34.
