Kayak

Abstract

The invention relates to a kayak comprising a light and stylish hull with a propeller mounted on the underside thereof, said propeller being actuatable by means of pedals mounted in front of and above a seat, the pedals and propeller being connected by means of a transmission that passes through the inside of the hull and below the surface thereof. Two rudders are arranged at the rear.

A kayak comprising: a hull having a seat for a user; a propeller mounted at a bottom of said hull at a rear thereof; a plurality of pedals mounted in front of and above said seat, said plurality of pedals cooperative with said propeller so as to actuate said propeller; a transmission cooperative with said propeller and said plurality of pedals, said transmission arranged at an inner area of said hull and underneath a surface of said hull; a pair of rudders mounted at the rear side of said hull, said pair of rudders being symmetrically located with respect to a median longitudinal plane of said hull; and a control positioned at one side of said seat, said control cooperative with a transmission cable that activates said pair of rudders, said hull forming a trilobular cross section at a bottom thereof, said trilobular cross section having a main central body and a pair of auxiliary side bodies, said main central body reducing in depth toward a rear part thereof and delimited at a stern of said hull by a cross-sectional plane, a front part of said main central body ends in a narrowing bow, said pair of auxiliary side bodies forming a pair of rear extensions with respect to said central body, said pair of rudders being mounted on said pair of rear extensions, said pair of auxiliary side bodies forming a pair of front extensions which narrow gradually and run separate from a central body bow without reaching an end thereof.

2. The kayak of claim 1, said hull forming a hold behind the seat which is accessible through an upper opening, said upper opening having a cover that can selectively close said upper opening.

3. The kayak of claim 1, said hull forming a recessed area in front of said seat, said recessed area being longitudinally crossed by an intermediate separation with a double wall projecting upwardly with respect to a surface of said hull and perpendicularly passed through by an axis of said pair of pedals, said pair of pedals having a pinion positioned between walls of said double wall, said transmission running through the walls of said double wall.

4. The kayak of claim 1, said central body having a lower projection at the rear part thereof, said propeller being mounted on said lower projection.

(2) FIG. 1 is a top plant view of the kayak.

(3) FIG. 2 shows a side elevation view of the same watercraft.

(4) FIG. 3 is a longitudinal schematic section of the kayak, according to the median longitudinal plane thereof.

(5) FIG. 4 is a section of the opening giving access to the hold, having a closing cover, taken according to the cutting line IV-IV of FIG. 1.

DETAILED DESCRIPTION OF AN EMBODIMENT

(7) FIGS. 1 and 2 show a plant and a side elevation view of the kayak of the invention, comprising a hull which, as it is represented in FIGS. 5 to 11, forms in the inner area thereof a trilobular cross section, having a main central body (1) and two auxiliary side bodies (2 and 3). The central body (1) features a height approximately constant between sections (9 and 11), whereas the bottom features an upward slope from section 9, reducing the height of said body, ending in a cross sectional plane (4) which limits this central body at the rear thereof. Meanwhile, the auxiliary side bodies (2 and 3) keep an approximately constant height over the entire length thereof and run substantially parallel to each other, extending, from the cross sectional plane (4) limiting the central body (1) at the rear part thereof, in portions (5 and 6) in each one of which there is a rudder (7) mounted, as it can be better appreciated in FIG. 2.

(8) On the other hand, the central body (1) forms a bow (8) that narrows gradually tapering to a point, the two side bodies (2 and 3) forming two front extensions (9 and 10), being substantially parallel, which run at both sides of the bow (8) of the central body, without reaching the end thereof.

(9) The stability of the craft is thus enhanced by means of the lateral bodies (2 and 3).

(10) The central body (1) is provided, at the top part thereof, with an intermediate platform on top of which a seat (11) or more (as many as the number of users the craft is designed for) are mounted by means of longitudinal rails (12) which make it possible to adjust the position of said seat/s.

(11) Behind the seat (11) the hull of the central body (1) forms a hold (13) that is provided with an access opening, FIG. 4, in the perimeter of which a ring (14) is mounted, for example one made of a plastic material, over which a closing cover (15) can be adjusted, preferably made of an elastically flexible material.

(12) In front of the seat (11) the central body (1) of the craft forms a recessed area (16), FIGS. 1 and 9, which is longitudinally crossed by an intermediate separation (17) featuring a double wall (18). A pedal mechanism (19 is mounted in this intermediate separation, the axis (20) of which passes perpendicularly through the two walls (18), between which the pinion (21) of this pedal mechanism is located.

(13) As it can be seen in FIG. 3, the hull is provided, at the rear part thereof, in the area having a smaller height, with a central projection (22) on which a propeller (23) is mounted, being actuated by the pedal mechanism (19) through a transmission (24) running over the inner area of the intermediate separation (17).

(14) As it can be seen in FIGS. 2 and 3, the pedal mechanism (19) is located in front of and slightly above the seat (11) surface.

(15) The rudders (7) can be actuated by means of a cable, not shown, from a control (25) located at one side of the seat (11), being both rudders (7) actuated together from the control (25).

(16) With such a conformation, the kayak of the invention can be easily actuated by a person situated in a comfortable position on the seat (11) and using the control (25) to control the rudders (7) from an easily accessible location. Furthermore, the kayak of the invention may also be propelled by means of a double-bladed paddle featuring a conventional design and operation.

(17) On the other hand, having a hold (13) with a water-tight cover (15) makes it possible to transport different objects or goods without the risk of them getting wet.

(18) Although in the example represented in the drawings the kayak is provided only with one seat, for a user, the watercraft could be provided with two or more seats, each one having a pedal mechanism associated to the chain or means of transmission for the propeller operation, all that by only increasing the hull length.
