Definitions

• holes 2 are made for the anchoring screws 3 to the side floats 7, and for the anchoring screws 4 of the longitudinal bars 5 that will support the seat and other passenger accommodation elements.
• the crossbars 1 keep the two lateral floats 7 together, being introduced into holes 8 that cross them transversely, while the longitudinal bars 5 provide rigidity to the floating structure of the water skate, when screwed with the screws 9 to the crossbars 1.
• Such longitudinal bars 5 are embedded in casings or holes 25 in the form of a box made in the upper part of the side floats 7 and that cross them transversely, so that once the bars 5 are placed and screwed, the surface of the float is completely She at the same level.
• the bars 5 have the peculiarity that their screwed ends to the side float 7 are introduced only to the plane of central symmetry thereof, so that in the case of the construction of a water skate of more than one place they can share the float with another equal bar belonging to another adjacent square.
• the side floats 7 have a cross section such that the upper part is flat to facilitate screwing and sliding of the pieces, while leaving widening towards its lower part, in the area between the rudders and the paddle wheels, to increase the buoyancy in the area where the user sits and slide over the surface of the water, trying to minimize the submerged part.
• the side floats 7 end in a thinner tip in front, to slide better over the water and compensate for the additional buoyancy due to the front float 10, as well as leaving enough width for the placement inside the entire structure of the elements of Propulsion and front float.
• crankshaft 11 struts on both sides the vane wheels 12 to an inner stop 13 of the crankshaft.
• This crankshaft is characterized in that its ends 14 are machined and finished in a square or polygonal section 15, so that the hollow of the axle 16 of the vane wheels 17 has the same section, thus allowing the integral rotation of the crankshaft 11 and the wheels of pallets 12 and their easy placement.
• these have at the ends of their tube or central axis 18 two holes 19 for the accommodation of two lateral pins 20, which allow to fix even more the paddle wheels 12 to the crankshaft 11.
• the crankshaft 11 has a length such that its ends finished in square or polygonal section 15 arrive just up to the plane of symmetry of the float 7, of form that would touch the end of another adjacent crankshaft 11.
• This end of square or polygonal section 15 cannot rotate, which is why it must be housed in a cylindrical symmetry piece 23 with an inner tube of the same section, which rotates to its once inside a box-shaped or parallelepiped piece 24 with a tube-shaped hollow that allows the rotation inside the cylindrical part 23.
• These pieces 23 and 24 are made of a low friction plastic material with high resistance to The same, since one turns in solidarity with the crankshaft 11 inside the other.
• this piece To prevent this piece from leaving its place, it has a cylindrical stop 29 at one end, so that when these stops are placed on the inner sides of the side floats 7, they cannot leave the structure. In the case of a multiplace skate, such parts are placed with this same arrangement alternately every two passengers.
• a tip-finished float 10 is placed, which can be placed by horizontal sliding below the crankshaft 11 and incorporating a gap 30 capable of accommodating the user's crankshaft, pedals and feet.
• Other embodiment of the invention would incorporate a front float of similar characteristics
• the float incorporates a skate-shaped bottom with one or two surfaces to support the feet, being open to the passage of water, serving only protection screen against the impact of waves and as an additional buoyancy element.
• the front float 10 requires a front curved bar 32 and two rear Z-bent bars 33 for attachment to the side floats 7.
• the bar 32 is attached to the front float 10 and can insert its ends into the inner holes of the pairs of holes 34 made in the sliding bezel 26, parallel to the longitudinal axis of the water skate, stopping thereon, and fixing with the pair of screws 35.
• the outer hole of the pair of holes 34 is free to engage the front float 10 of the other passenger, if any.
• the two bars folded in Z 33 are introduced in tubular housings 36 made in the sliding trim pieces 26, and pivoting on this axis, are anchored to flanges 37 practiced in the lower part of the same. These bars 33 anchor the structure and allow the front float 10 not to be released or broken if the passenger supports the feet strongly.
• the rudders 38 have a pivot 39, with a stop washer 40, and are introduced in the tubular housings 41 for the rudders 38, practiced in the stern of the side floats 7. These rudders 38 are fixed in the housings 41, using a pin 42 that crosses it, as well as a piece with a double outer pulley 43, keeping the rudders 38 placed in that position.
• the double pulley piece 43 uses one of them to accommodate the synchronization rope of the rudders 44, which keeps the rudders 38 parallel at all times, and the other to fix the control rope of the rudder 45, which is fixed to the piece with double pulley 43 using hook rings 46 that prevent sliding.
• the double pulley piece 43 has two upper stops 47 located diametrically opposite, so that they restrict the angle of rotation of the rudders 38 to less than 180 ° when tripping over the lugs 48 located very close to the side floats 7, which at the same time they serve to guide the rudder control rope 45 towards the double pulley piece 43.
• the side floats 7 have keels 49 that direct the flow of water towards the rudders 38, increasing the maneuverability of the water skate.
• the rudder control rope 45 runs embedded between a pair of longitudinal flanges 50 arranged along the upper part of the side float 7, between the double pulley piece 43 and the rudder support pylon 51, which is anchored to the float side 7 by means of screws 52.
• the rudder control rope 45 rises from the flanges 50 through the inside of the pylon 51 to a support end with two washers or tubes integral with the pylon 51, between which two tubes with an inner hole are fitted square 53 and a cylindrical side stop that prevents its exit from the hole, as well as a reel 54, also with a square inner hole.
• the square pivot 55 of the flywheel 56 is fitted and slid, using a pin 57 as a stopper that crosses the square pivot 55 of the flywheel 56.
• the spool 54 has two rings 57 in which the ends of the rudder control rope 45.
• the reel 54 also does it, winding one end of the control rope of the rudder 45 hooked to the rings 57 and unwinding the other. It is thus possible to pull the piece with double pulley 43 in the correct direction and turn the two rudders 38 in a synchronized manner.
• the steering wheel 56 is rotated comfortably with the handle 58 and its length can be adjusted by adjusting the distance of the square pivot 55 to the passenger's seat or arm.
• the synchronization rope of the rudders 44 extends to all the parts in double pulley of each and every one of the rudders of the boat, using the appropriate hook rings.
