DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
E! patín acuático tiene un único concepto inventivo pero varias formas de realización posibles, empleando las mismas piezas y elementos en todas ellas pero cambiando su disposición. Describiremos pues con detalle una de las formas de realización y posteriormente describiremos las características y difrencias de las distintas formas posibles de realización.AND! Water skate has a unique inventive concept but several possible embodiments, using the same parts and elements in all of them but changing its arrangement. We will then describe in detail one of the embodiments and then describe the characteristics and differences of the different possible embodiments.
El patín acuático consta, como se ve en Ia Figura 13 y en Ia Figura 14, de dos plataformas de flotación, delantera 1 y trasera 2, que se pueden plegar Ia una sobre Ia otra, de forma coincidente, según un eje 3 transversal a Ia embarcación. Ambas plataformas de flotación están realizadas en una sola pieza, o en varias, convenientemente pegadas, atornilladas, remachadas o unidas por cualquier método, con tal de que cada una de ellas forme una sola unidad estructuralmente rígida y de gran robustez. Cada una de estas dos plataformas de flotación 1 y 2 son simétricas respecto a un plano imaginarlo de simetría longitudinal vertical que pasa por el centro de Ia embarcación.The water skate consists, as seen in Figure 13 and Figure 14, of two flotation platforms, front 1 and rear 2, which can be folded one on the other, coincidentally, along an axis 3 transverse to The boat Both flotation platforms are made in one piece, or in several, conveniently glued, screwed, riveted or joined by any method, provided that each of them forms a single structurally rigid and highly robust unit. Each of these two flotation platforms 1 and 2 are symmetrical with respect to an imaginary plane of vertical longitudinal symmetry that passes through the center of the vessel.
Ambas plataformas de flotación, 1 y 2, disponen, cada una de ellas, de una pieza o elemento central, a modo de bandeja, que sirve de unión para los elementos de su estructura, una delantera 4 y otra trasera 5, simétricas respecto al plano de simetría longitudinal vertical que pasa por el centro de Ia embarcación. Ambas unen a modo de puente dos semiflotadores delanteros 6 en Ia plataforma de flotación delantera 1 , iguales entre sí y simétricos respecto al plano de simetría longitudinal vertical que pasa por el centro de Ia embarcación, y dos semiflotadores traseros 7 en Ia plataforma de flotación trasera 2, también iguales entre sí y simétricos respecto al plano de simetría longitudinal vertical que pasa por el centro de Ia embarcación. La bandeja central 5 de Ia plataforma de flotación trasera 2 dispone de unas molduras antideslizantes 8 y sirve de asiento para el pasajero, teniendo para ello una forma adecuada para que resulte cómodo. La bandeja central 4 de Ia plataforma de flotación delantera 1 es más pequeña, y sirve de unión entre los dos semiflotadores delanteros 6. Las plataformas de flotación 1 y 2 disponen de unos tubos a modo de bisagra 9 y 10, por dentro de los cuales se ensarta, transversalmente a Ia embarcación, una barra 11, cilindrica, rígida y gruesa, como eje de plegado de Ia misma, que se fija con una arandela de tope 12 y un pasador 13, como se aprecia en Ia Figura 12, Ia Figura 13 y Ia Figura 14.Both flotation platforms, 1 and 2, each have a central part or element, as a tray, which serves as a union for the elements of its structure, a front 4 and a rear 5, symmetrical with respect to the Vertical longitudinal symmetry plane that passes through the center of the boat. Both join as bridge two front semi-floats 6 on the front flotation platform 1, equal with each other and symmetrical with respect to the vertical longitudinal symmetry plane that passes through the center of the boat, and two rear semi-floats 7 on the rear flotation platform 2, also equal to each other and symmetrical with respect to the vertical longitudinal symmetry plane that passes through the center of the boat. The central tray 5 of the rear flotation platform 2 has non-slip moldings 8 and serves as a seat for the passenger, having a suitable shape for it to be comfortable. The central tray 4 of the front flotation platform 1 is smaller, and serves as a connection between the two front semi-floats 6. The flotation platforms 1 and 2 have hinged tubes 9 and 10, inside which a bar 11, cylindrical, rigid and thick, is attached, transversely to the vessel, as a folding axis thereof, which is fixed with a stop washer 12 and a pin 13, as seen in Figure 12, Figure 13 and Figure 14.
Como se ve en Ia Figura 5 y en Ia Figura 6, cuando Ia embarcación se encuentra plegada, Ia plataforma de flotación delantera 1 descansa de forma coincidente con Ia plataforma de flotación trasera 2, haciendo tope sobre los flotadores o alguno de los elementos adosados a los mismos. Cuando Ia embarcación se encuentra desplegada, los semiflotadores delanteros 6 y los semiflotadores traseros 7 se alinean para constituir conjuntamente dos flotadores laterales alargados, semejantes a los de un catamarán, partidos por Ia mitad. El corte en Ia zona de contacto entre los semiflotadores 6 y 7 es tal que no hay discontinuidades, oquedades ni salientes bruscos, sino que se consigue un perfil continuo e hidrodinámico entre ambos que facilita el deslizamiento de Ia embarcación en el agua. Cada uno de los semiflotadores 6 y 7 presenta longitudinal y simétricamente, en su parte inferior, un engrosamiento en forma de quilla 14, que confiere a los mismos solidez y resistencia frente a choques y roces contra el suelo durante el transporte, acabando en unas aletas finales posteriores 15, fusionadas a los semiflotadores traseros 7.As seen in Figure 5 and Figure 6, when the boat is folded, the front flotation platform 1 rests coincidentally with the rear flotation platform 2, stopping on the floats or any of the elements attached to the same. When the vessel is deployed, the front semi-floats 6 and the rear semi-floats 7 line up to jointly constitute two elongated side floats, similar to those of a catamaran, split in half. The cut in the contact area between the semi-floats 6 and 7 is such that there are no discontinuities, cavities or sharp projections, but a continuous and hydrodynamic profile between the two that facilitates the sliding of the boat in the water is achieved. Each of the semi-floats 6 and 7 has longitudinally and symmetrically, in its lower part, a keel-shaped thickening 14, which gives the same strength and resistance against shocks and rubs against the ground during transport, ending in fins later finals 15, fused to the rear semi-floats 7.
Estas aletas 15 son responsables de un direccionamiento eficiente del flujo del agua hacia los timones de dirección 16, para aumentar Ia maniobrabilidad de una embarcación tan pequeña. Éstas están reforzadas para evitar su rotura por choque o roce con el suelo, ya que también sirven para proteger ambos timones 16 cuando se transporta por tierra.These fins 15 are responsible for an efficient direction of the water flow towards the steering rudders 16, to increase the maneuverability of such a small boat. These are reinforced to avoid their breakage by shock or rubbing with the ground, since they also serve to protect both rudders 16 when transported by land.
Como se ve en el despiece de Ia Figura 12, la barra 11 del eje de plegado de Ia embarcación ensarta, en sus extremos, dos palancas de control del timón 17, iguales y simétricas, unas ruedas laterales 18 que protegen las palancas de control del timón 17 contra choques o roces cuando la embarcación plegada se arrastra por el suelo, y unas arandelas antifricción 19 que suavizan el movimiento de las palancas de control del timón 17.As seen in the exploded view of Figure 12, the bar 11 of the folding axis of the vessel struts, at its ends, two control levers of the rudder 17, equal and symmetrical, side wheels 18 that protect the control levers of the rudder 17 against shocks or friction when the folded boat crawls on the ground, and anti-friction washers 19 that soften the movement of the control levers of rudder 17.
Para evitar el plegado del patín acuático mientras se desplaza por el agua, dos bastidores en forma de U de perfil tubular (redondo, cuadrado, rectangular o poligonal), delantero 20 y trasero 21 , que pueden ser huecos y / o macizos, mantienen alineadas y ancladas rígidamente las dos plataformas de flotación, delantera 1 y trasera 2.To avoid folding the water skate while traveling through the water, two U-shaped racks of tubular profile (round, square, rectangular or polygonal), front 20 and rear 21, which can be hollow and / or solid, keep aligned and rigidly anchored the two flotation platforms, front 1 and rear 2.
Como se ve en Ia Figura 9 y en Ia Figura 10, Ia plataforma de flotación delantera 1 tiene al menos un par de salientes o ensanchamientos 22 (en el lado interior, en el lado exterior o en Ia parte superior de los semiflotadores delanteros 6, según Ia forma de realización de Ia invención), dispuestos simétricamente con respecto al plano de simetría longitudinal vertical que pasa por el centro de Ia embarcación. Cada uno de estos salientes o ensanchamientos 22 está atravesado longitudinalmente por un agujero 23. La bandeja central 4 de Ia plataforma de flotación delantera 1 también está atravesada por un par de agujeros 24, practicados longitudinalmente y de forma simétrica con respecto al plano de simetría longitudinal vertical que pasa por el centro de Ia embarcación, (en el lado interior, en el lado exterior o en Ia parte superior de los semiflotadores delanteros 6, según Ia forma de realización de Ia invención).As seen in Figure 9 and Figure 10, the front flotation platform 1 has at least one pair of projections or widenings 22 (on the inner side, on the outer side or on the top of the front semi-floats 6, according to the form of embodiment of the invention), arranged symmetrically with respect to the plane of vertical longitudinal symmetry that passes through the center of the boat. Each of these projections or widenings 22 is crossed longitudinally by a hole 23. The central tray 4 of the front flotation platform 1 is also crossed by a pair of holes 24, practiced longitudinally and symmetrically with respect to the longitudinal symmetry plane vertical that passes through the center of the boat, (on the inner side, on the outer side or on the top of the front semi-floats 6, according to the embodiment of the invention).
La plataforma de flotación trasera 2 también se encuentra atravesada por uno o dos pares de agujeros paralelos 25, también longitudinales y practicados de forma simétrica con respecto al plano de simetría longitudinal vertical que pasa por el centro de Ia embarcación (en el lado interior, en el lado exterior y / o en Ia parte superior de los semiflotadores traseros 7, según Ia forma de realización de Ia invención), con Ia particularidad de que al menos el par de agujeros 24 y uno de los pares de agujeros 25 están practicados a Ia misma altura, con los de lado derecho y los del lado izquierdo de Ia embarcación perfectamente alineados entre sí, ya que son los responsables de anclar el bastidor en U delantero 20.The rear flotation platform 2 is also crossed by one or two pairs of parallel holes 25, also longitudinal and practiced symmetrically with respect to the vertical longitudinal symmetry plane that passes through the center of the boat (on the inner side, in the outer side and / or in the upper part of the rear semi-floaters 7, according to the embodiment of the invention), with the particularity that at least the pair of holes 24 and one of the pairs of holes 25 are made to the same height, with those on the right side and those on the left side of the boat perfectly aligned with each other, since they are responsible for anchoring the front U-frame 20.
Los pares dé agujeros 23, 24 y 25 tienen todos ellos el mismo perfil que los tubos de los bastidores en forma de U 20 y 21. Las dos ramas del bastidor en forma de U 20 se pueden introducir así consecutivamente en los agujeros 23, 24 y 25 de ambos lados, derecho e izquierdo del patín acuático, pudiendo deslizarse longitudinalmente con respecto a Ia embarcación, y manteniendo las dos plataformas de flotación 1 y 2 abiertas, sin posibilidad de plegado, cuando sus extremos están introducidos en los pares de agujeros 25 de Ia plataforma de flotación posterior 2.The pairs of holes 23, 24 and 25 all have the same profile as the tubes of the U-shaped frames 20 and 21. The two branches of the U-shaped frame 20 can thus be introduced consecutively into the holes 23, 24 and 25 of both sides, right and left of the water skate, being able to slide longitudinally with respect to the boat, and keeping the two flotation platforms 1 and 2 open, without the possibility of folding, when their ends are introduced into the pairs of holes 25 of the rear flotation platform 2.
Sacando los extremos del bastidor en forma de U 20 de tales pares de agujeros 25 se permite el plegado de la embarcación. Esto se aprecia en Ia Figura 5 y en Ia Figura 6. La plataforma de flotación trasera 2 tiene al menos un par de salientes o ensanchamientos 26 (en el lado interior, en el lado exterior o en Ia parte superior de los semiflotadores traseros 7, según Ia forma de realización de Ia invención), dispuestos simétricamente con respecto al plano de simetría longitudinal vertical que pasa por el centro de Ia embarcación. Cada uno de estos salientes o ensanchamientos 26 está atravesado longitudinalmente por un agujero 27. La bandeja central 5 de Ia plataforma de flotación trasera 2 también está atravesada por un par de agujeros 28, longitudinalmente y de forma simétrica con respecto al plano de simetría longitudinal vertical que pasa por el centro de Ia embarcación (en el lado interior, en el lado exterior o en Ia parte superior de los semiflotadores traseros 7, según Ia forma de realización de Ia invención). La plataforma de flotación delantera 1 se encuentra atravesada por uno o dos pares de agujeros paralelos 29, también longitudinalmente y de forma simétrica con respecto al plano de simetría longitudinal vertical que pasa por el centro de Ia embarcación (en el lado interior, en el lado exterior y / o en Ia parte superior de los semiflotadores delanteros 6, según Ia forma de realización de Ia invención), con Ia particularidad de que al menos el par de agujeros 28 y uno de los pares de agujeros 29 están practicados a Ia misma altura, con los de lado derecho y los del lado izquierdo de Ia embarcación perfectamente alineados entre sí, ya que son los responsables de anclar el bastidor en U trasero 21. Los pares de agujeros 27, 28 y 29 tienen todos ellos el mismo perfil que los tubos de los bastidores en forma de U 20 y 21. Las dos ramas del bastidor en forma de U 21 se pueden introducir así consecutivamente en los agujeros 27, 28 y 29 de ambos lados, derecho e izquierdo del patín acuático, pudiendo deslizarse longitudinalmente con respecto a Ia embarcación, y manteniendo las dos plataformas de flotación 1 y 2 abiertas, sin posibilidad de plegado, cuando sus extremos están introducidos en los pares de agujeros 29 de Ia plataforma de flotación delantera 1.Removing the ends of the U-shaped frame 20 from such pairs of holes 25 allows folding the boat. This is seen in Figure 5 and Figure 6. The rear flotation platform 2 has at least one pair of projections or widenings 26 (on the inner side, on the outer side or on the top of the rear semi-floats 7, according to the embodiment of the invention), arranged symmetrically with respect to the vertical longitudinal symmetry plane that passes through the center of the boat. Each of these projections or widenings 26 is crossed longitudinally by a hole 27. The central tray 5 of the rear flotation platform 2 is also crossed by a pair of holes 28, longitudinally and symmetrically with respect to the vertical longitudinal symmetry plane passing through the center of the boat (on the inner side, on the outer side or on the top of the rear semi-floats 7, according to the embodiment of the invention). The front flotation platform 1 is crossed by one or two pairs of parallel holes 29, also longitudinally and symmetrically with respect to the vertical longitudinal symmetry plane that passes through the center of the boat (on the inner side, on the side exterior and / or in the upper part of the front semi-floaters 6, according to the embodiment of the invention), with the particularity that at least the pair of holes 28 and one of the pairs of holes 29 are made at the same height , with those on the right side and those on the left side of the boat perfectly aligned with each other, since they are responsible for anchoring the rear U-frame 21. The pairs of holes 27, 28 and 29 all have the same profile as the tubes of the U-shaped frames 20 and 21. The two branches of the U-shaped frame 21 can thus be introduced consecutively into the holes 27, 28 and 29 of both sides, right and left of the water skate, being able to slide longitudinally with respect to the boat, and keeping the two flotation platforms 1 and 2 open, without the possibility of folding, when their ends are inserted in the pairs of holes 29 of the front flotation platform 1.
Sacando los extremos del bastidor en forma de U 21 de tales pares de agujeros 25 se permite el plegado de Ia embarcación. Esto se aprecia en Ia Figura 5 y en Ia Figura 6. Al disponer no de uno, sino de dos bastidores en U contribuyendo a mantener el patín acuático desplegado, se tiene mayor seguridad de que éste se mantenga así durante Ia flotación, aunque uno de los dos bastidores se rompiera o se saliera de su sitio.Removing the ends of the U-shaped frame 21 from such pairs of holes 25 allows folding the boat. This can be seen in Figure 5 and Figure 6. By having not one, but two U-frames contributing to keep the water skate unfolded, it is more certain that it remains so during flotation, although one of The two racks would break or get out of place.
Como se ve en Ia Figura 17 y en Ia Figura 18, el bastidor en U delantero 20 dispone de unos pedales 30, alojados en unos goznes de giro 31, atornillados al propio bastidor en U delantero 20, que permiten el giro de al menos una rueda de paletas 32, de un tamaño tal que permite el plegado de Ia estructura del patín acuático sin problemas de espacio. El bastidor en U trasero 21 dispone de unos goznes 33 sobre los que pivota una barra de perfil redondo doblada en U 34 que soporta el respaldo 35 del pasajero. El bastidor en U delantero 20 tiene, practicados simétrica y verticalmente en ambas ramas del mismo, un par de agujeros 36, iguales y simétricos respecto al plano de simetría vertical longitudinal que pasa por ei centro de Ia embarcación, y un par de ranuras 37, también ¡guales y simétricas respecto al plano de simetría vertical longitudinal que pasa por el centro de Ia embarcación.As seen in Figure 17 and Figure 18, the front U-frame 20 has some pedals 30, housed in turning hinges 31, screwed to the front U-frame 20 itself, which allow the rotation of at least one paddle wheel 32, of a size that allows the folding of the structure of the water skate without problems of space. The rear U-frame 21 has hinges 33 on which a round U-bent round bar 34 pivots that supports the passenger's backrest 35. The front U-frame 20 has, symmetrically and vertically in both branches thereof, a pair of holes 36, equal and symmetrical with respect to the longitudinal vertical symmetry plane that passes through the center of the vessel, and a pair of grooves 37, also equal and symmetrical with respect to the plane of vertical symmetry longitudinal that passes through the center of the boat.
Tanto en el par de agujeros 36 como en el par de ranuras 37 se pueden encajar un par de pasadores 38, que atraviesan verticalmente a su vez los salientes 22 de ios semiflotadores delanteros 6. Cuando el par de agujeros 36 está atravesado por este par de pasadores 38, el bastidor en U delantero 20 está anclado y no puede deslizarse longitudinalmente, estando colocado de forma que sus extremos no se introducen en el par o pares de . agujeros longitudinales 25 de Ia plataforma de flotación trasera 2, Io que permite que el patín acuático se pueda plegar sobre su eje 3. Cuando el parde pasadores 38, atravesando los salientes 22 de los semiflotadores delanteros 6, están colocados en el par de ranuras 37, el bastidor delantero 20 puede desplazarse longitudinalmente según el eje de Ia embarcación una longitud igual a Ia de este par de ranuras 37, permitiendo el desplazamiento de los pedales 30 y de Ia rueda de paletas 32 con respecto a Ia posición del pasajero, pero de forma que en cualquiera de estas posiciones sus extremos están introducidos en el par o pares de agujeros longitudinales 25 de Ia plataforma de flotación trasera 2, de forma que el patín acuático no puede plegarse sobre su eje 3.A pair of pins 38 can be fitted both in the pair of holes 36 and in the pair of slots 37, which pass vertically in turn the protrusions 22 of the front semi-floats 6. When the pair of holes 36 is crossed by this pair of pins 38, the front U-frame 20 is anchored and cannot slide longitudinally, being positioned so that its ends are not inserted into the pair or pairs of. longitudinal holes 25 of the rear flotation platform 2, which allows the water skate to be folded on its axis 3. When the pin wall 38, crossing the projections 22 of the front semi-floats 6, are placed in the pair of slots 37 , the front frame 20 can move longitudinally along the axis of the boat a length equal to that of this pair of grooves 37, allowing the displacement of the pedals 30 and the paddle wheel 32 with respect to the position of the passenger, but of such that in any of these positions its ends are inserted in the pair or pairs of longitudinal holes 25 of the rear flotation platform 2, so that the water skate cannot be folded on its axis 3.
Para fijar posiciones intermedias de desplazamiento del bastidor en U delantero 20, de los pedales 30 y de Ia rueda de paletas 32 con respecto al pasajero, unas pequeñas asas o anclajes pivotantes y / o deslizantes 39, colocadas simétricamente en ambas ramas del bastidor 20, pueden girar y / o deslizarse sobre unas pequeñas bisagras o soportes 40, encajándose según posiciones prefijadas en dos filas de muescas o agujeros 41, practicadas simétricamente en el lado interior, exterior o superior (según Ia forma de realización de Ia invención) de los semiflotadores delanterosTo fix intermediate positions of displacement of the front U-frame 20, of the pedals 30 and of the vane wheel 32 with respect to the passenger, small handles and pivoting and / or sliding anchors 39, symmetrically placed on both branches of the frame 20, they can rotate and / or slide on small hinges or supports 40, fitting according to predetermined positions in two rows of notches or holes 41, symmetrically practiced on the inner, outer or upper (according to the embodiment of the invention) of the front semi-floaters
6 y / o en Ia plataforma central 5. El pasajero usa ambas manos para desbloquear tales anclajes pivotantes y / o deslizantes 39 y los empuja hacia delante o hacia atrás, así como los pedales usando los pies, anclando el bastidor en U delantero 20 en Ia posición deseada.6 and / or in the central platform 5. The passenger uses both hands to unlock such pivoting and / or sliding anchors 39 and pushes them forward or backward, as well as the pedals using the feet, anchoring the front U-frame 20 in The desired position.
El bastidor en U trasero 21 tiene, practicados simétrica y verticalmente en ambas ramas del mismo, un par de agujeros 42, iguales y simétricos respecto al plano de simetría vertical' longitudinal que pasa por el centro de Ia embarcación, así como un par de ranuras 43, también iguales y simétricas respecto al plano de simetría vertical longitudinal que pasa por el centro de Ia embarcación.The U - frame rear 21 has, symmetrical practiced and vertically in both branches thereof, a pair of holes 42, equal and symmetrical with respect to the plane vertical 'longitudinal symmetry passing through the center of Ia vessel, and a pair of slots 43, also equal and symmetrical with respect to the longitudinal vertical symmetry plane that passes through the center of the vessel.
Tanto en el par de agujeros 42 como en el par de ranuras 43 se pueden encajar verticalmente un par de pasadores 44, que atraviesan a su vez los salientes 26 de los lados interiores de los semiflotadores traseros 7. Cuando el par de pasadores 44, atravesando los salientes 26, están colocados en el par de agujeros 42, el bastidor en U trasero 21 está anclado y no puede deslizarse longitudinalmente, estando colocado de forma que sus extremos no se introducen en el par o pares de agujeros longitudinales 29 de Ia plataforma de flotación delantera 1, con Io que no impide que el patín acuático se pueda plegar sobre su eje 3.In both the pair of holes 42 and the pair of slots 43, a pair of pins 44 can be fitted vertically, which in turn pass through the projections 26 of the inner sides of the rear semi-floats 7. When the pair of pins 44, passing through the projections 26, are placed in the pair of holes 42, the rear U-frame 21 is anchored and cannot slide longitudinally, being positioned so that its ends are not introduced in the pair or pairs of longitudinal holes 29 of the platform front flotation 1, with what does not prevent the water skate from folding on its axis 3.
Cuando el par de pasadores 44, atravesando los ensanchamientos 26 de los flotadores traseros 7, están colocados en el par de ranuras 43, el bastidor trasero 21 puede desplazarse longitudinalmente según el eje de Ia embarcación una longitud igual a Ia del par de ranuras 43, permitiendo el desplazamiento de Ia barra de soporte 38 del respaldo 39 con respecto a Ia posición del pasajero, pero de forma que en cualquiera de estas posiciones sus extremos están introducidos en el par o pares de agujeros longitudinales 29 de Ia plataforma de flotación delantera 1, de forma que el patín acuático no puede plegarse sobre su eje 3.When the pair of pins 44, crossing the widenings 26 of the rear floats 7, are placed in the pair of slots 43, the rear frame 21 can move longitudinally along the axis of the vessel a length equal to that of the pair of slots 43, allowing the displacement of the support bar 38 of the backrest 39 with respect to the position of the passenger, but in any way of these positions its ends are introduced in the pair or pairs of longitudinal holes 29 of the front flotation platform 1, so that the water skate cannot be folded on its axis 3.
Para fijar posiciones intermedias de desplazamiento del bastidor en U trasero 21, y de inclinación del respaldo 35 para acomodar al pasajero, dos barras dobladas en L 45, atornilladas, remachadas o pegadas al bastidor en U trasero 21, llevan en sus extremos dos asas o anclajes 46, pivotantes y / o deslizantes, que encajan en dos filas simétricas de muescas o agujeros 47, practicadas en los lados exteriores de los semiflotadores traseros 7, que fijan el mismo en Ia posición deseada, de forma que puedan ser fácilmente asidos por el pasajero para desbloquear, desplazar y volver a bloquear todo el conjunto usando ambas manos a Ia vez.To fix intermediate positions of displacement of the rear U-frame 21, and of inclination of the backrest 35 to accommodate the passenger, two bars bent in L 45, screwed, riveted or glued to the rear U-frame 21, carry at their ends two handles or anchors 46, pivoting and / or sliding, which fit into two symmetrical rows of notches or holes 47, made on the outer sides of the rear semi-floats 7, which fix it in the desired position, so that they can be easily grasped by the passenger to unlock, move and re-lock the entire assembly using both hands at the same time.
Cuando se pliega el patín acuático, los dos bastidores en U 20 y 21 quedan unidos mediante las dos piezas terminales 48, que sirven de anclaje de ambas y de asa para el transporte por arrastre del patín acuático, manteniéndolo cerrado. Para facilitar el transporte del mismo, las quillas de los flotadores vienen equipadas con unas pequeñas ruedas reforzadas 49, dispuestas en el plano vertical de simetría de las mismas.When the water skate is folded, the two U-frames 20 and 21 are joined together by the two end pieces 48, which serve as an anchor for both of them and as a handle for dragging the water skate, keeping it closed. To facilitate its transport, the keels of the floats are equipped with small reinforced wheels 49, arranged in the vertical plane of symmetry thereof.
El respaldo 35 del pasajero se encuentra ensartado, mediante una barra recta 50 y una arandela tope 51 con un pasador 52, en Ia plataforma de flotación posterior 2 mediante las bisagras 53 y 54. Unas pestañas o ganchos posteriores 55 permiten su enganche y desenganche a Ia barra de soporte y regulación del respaldo, posibilitando abatir el respaldo hacia abajo al plegar Ia embarcación, para permitir el acoplamiento de Ia rueda de paletas 32.The passenger's backrest 35 is threaded, by means of a straight bar 50 and a stop washer 51 with a pin 52, on the rear flotation platform 2 by means of hinges 53 and 54. Tabs or rear hooks 55 allow it to be engaged and disengaged. The support and backrest adjustment bar, making it possible to lower the backrest when folding the boat, to allow the coupling of the paddle wheel 32.
Los goznes de giro 31 y 33, atornillados a los bastidores en U 20 y 21, hacen las veces de tope. Tales elementos tropiezan con los salientes 22 y 26 de los semiflotadores, de forma que evitan siempre que los bastidores se salgan de los pares de agujeros 23 y 24, y 27 y 28, respectivamente, manteniéndolos siempre ensartados en los mismos, a no ser que se desatornillen de los bastidores en U 20 y 21. Por su posición no evitan, sin embargo, que los bastidores en U 20 y 21 se salgan de los pares de agujeros 25 y 29 y que por tanto el patín acuático se pueda plegar, ya que Ia función de anclaje recae sobre los pares de pasadores 38 y 44.The hinges 31 and 33, screwed to the U-frames 20 and 21, make the butt times Such elements collide with the protrusions 22 and 26 of the semi-floaters, so that they always prevent the frames from leaving the pairs of holes 23 and 24, and 27 and 28, respectively, always keeping them strung thereon, unless unscrew from the U-20 and 21 frames. Due to their position, they do not prevent the U-20 and 21 frames from leaving the pairs of holes 25 and 29 and therefore the water skate can be folded, as that the anchoring function falls on the pairs of pins 38 and 44.
La plataforma de flotación trasera 2 tiene en sus extremos de popa unos agujeros verticales 56, que permiten el encaje y giro vertical de los dos timones 16, que quedan confinados en su posición mediante unas piezas de fijación con una polea horizontal 57.The rear flotation platform 2 has at its stern ends vertical holes 56, which allow the vertical engagement and rotation of the two rudders 16, which are confined in position by means of fixing pieces with a horizontal pulley 57.
Por esta polea horizontal 57 discurre una cuerda de control del timón 58, unida a las dos palancas de control del timón 17, sincronizando y arrastrando en su giro los timones 16. Como se ve en Ia Figura 15, al empujar hacia adelante cualquiera de las dos palancas 17, se tensa Ia cuerda de control del timón 58, se arrastran los timones hacia el lado escogido y simultáneamente Ia cuerda de control del timón 58 tira de Ia otra palanca 17 hacia atrás. Al tirar de una o de las dos palancas de control del timón 17 hacia atrás se destensa Ia cuerda de control de timón 58, Io que permite el plegado del patín acuático sin desengancharla, ganando facilidad de uso y tiempo de ocio con ello. Los extremos de las palancas de control de timón 17 quedan protegidos del contacto con el suelo por las ruedas laterales 18.On this horizontal pulley 57 runs a rudder control rope 58, attached to the two control levers of rudder 17, synchronizing and dragging rudders 16 in its turn. As seen in Figure 15, when pushing any of the Two levers 17, the rudder control rope 58 is tensioned, the rudders are dragged to the chosen side and simultaneously the rudder control rope 58 pulls the other lever 17 backwards. Pulling one or both of the rudder control levers 17 backwards pulls the rudder control rope 58, which allows folding the water skate without unhooking it, gaining ease of use and leisure time with it. The ends of the rudder control levers 17 are protected from contact with the ground by the side wheels 18.
La embarcación dispone de dos cajones laterales 59, constituidos por dos pequeños huecos simétricamente practicados en Ia parte superior de los semiflotadores traseros 7, de forma que quedan a ambos lados del respaldo 35 y del asiento, cerrándose cada uno de ellos con una pequeña tapa basculante 60, que gira sobre una bisagra 61, en sentido transversal al de Ia embarcación. Un pequeño tope 62 limita el ángulo de apertura de Ia tapa 60 y un asidero 63 facilita poder abrirla y cerrarla. Las tapas 60 tienen una superficie superior curvada que les permite ser empleadas como reposabrazos. Al plegarse Ia embarcación estas tapas 60 se introducen, encajando perfectamente, en sendos huecos 64 practicados en Ia parte superior de los semiflotadores delanteros 6 de Ia plataforma de flotación delantera 1, de forma que los cajones no impiden ni dificultan el plegado de Ia estructura. Tanto los cajones 59 como los huecos 64 tienen unos pequeños agujeros que permiten el drenaje de agua. Para plegar Ia embarcación, se procede en cinco fases: a) Desbloqueando los pares de asas pivotantes y / o deslizantes 39 y 46, se sacan los pares de pasadores 38 y 44, tanto de los pares de agujeros que atraviesan verticalmente los pares de salientes 22 y 26 de los semiflotadores delanteros 6 y traseros 7, respectivamente, como de los pares de ranuras 37 y 43 de los bastidores en U delantero 20 y trasero 21 , respectivamente. b) Se sacan hacia afuera los bastidores en U delantero 20 y trasero 21 , haciendo coincidir los pares de agujeros 36 y 42 de los mismos con los pares de agujeros verticales que atraviesan los pares de salientes 22 y 26 de los semiflotadores delanteros 6 y traseros 7, respectivamente. c) Se introducen los pares de pasadores 38 y 44 atravesando los agujeros verticales de los salientes 22 y 26 de los semiflotadores delanteros 6 y traseros 7 y los pares de agujeros 36 y 42 de los bastidores en U delantero 20 y trasero 21. d) Se saca Ia barra 34 de las pestañas 55 del respaldo 35 y se abate éste hacia atrás, el cual queda colgando hacia abajo, encajado entre Ia rueda de paletas 32 y el bastidor en U trasero 21. e) Cogiendo el asa 48 delantera, se pliega Ia parte delantera de Ia embarcación sobreThe boat has two lateral drawers 59, consisting of two small holes symmetrically made in the upper part of the rear semi-floats 7, so that they remain on both sides of the backrest 35 and the seat, closing each of them with a small tilting cover 60, which rotates on a hinge 61, transverse to that of the vessel. A small stop 62 limits the opening angle of the lid 60 and a handle 63 makes it easy to open and close it. The covers 60 have a curved upper surface that allows them to be used as armrests. When the boat is folded, these covers 60 are inserted, fitting perfectly, into two holes 64 made in the upper part of the front semi-floats 6 of the front flotation platform 1, so that the drawers do not prevent or hinder the folding of the structure. Both the drawers 59 and the holes 64 have small holes that allow water to drain. To fold the boat, we proceed in five phases: a) Unlocking the pairs of pivoting and / or sliding handles 39 and 46, the pairs of pins 38 and 44 are removed, both from the pairs of holes that cross the pairs of projections vertically 22 and 26 of the front and rear semi-floats 6, respectively, as of the pairs of grooves 37 and 43 of the front and rear U-frames 20, respectively. b) The front 20 and rear 21 U-racks are pulled out, matching the pairs of holes 36 and 42 thereof with the pairs of vertical holes that cross the pairs of projections 22 and 26 of the front and rear semi-floats 6 7, respectively. c) The pairs of pins 38 and 44 are introduced through the vertical holes of the projections 22 and 26 of the front 6 and rear semi-floats 7 and the pairs of holes 36 and 42 of the front and rear U-frames 20. d) The bar 34 is removed from the tabs 55 of the backrest 35 and the latter is folded back, which is hanging down, fitted between the paddle wheel 32 and the rear U-frame 21. e) Taking the front handle 48, the front part of the boat is folded over
Ia trasera, acoplando las dos piezas 48 entre sí y cerrando con el anclaje o muesca de que disponga.The rear, coupling the two pieces 48 together and closing with the anchor or notch available.
Para abrir el patín se realiza el proceso inverso.To open the skate the reverse process is performed.
Siguiendo el concepto inventivo descrito anteriormente, hay varias realizaciones posibles de Ia invención, cuyos dibujos simplificados se pueden ver en las Figuras 19 a 22. En un grupo A de tres realizaciones posibles de Ia invención, las ramas de los dos bastidores en U 20 y 21 , los salientes de los semiflotadores 22 y 26, y los pares de agujeros 23, 24, 25, 27, 28, 29, se encuentran en los lados interiores de los semiflotadores 6 y 7. Con esta disposición, las ramas de los bastidores en U 20 y 21 , y por tanto los elementos anteriormente enumerados que permiten su alojamiento y desplazamiento horizontal, pueden estar a diferente altura, con dos planos de deslizamiento horizontales distintos para los dos bastidores en U 20 y 21 (caso de las formas de realización A1 yFollowing the inventive concept described above, there are several possible embodiments of the invention, whose simplified drawings can be seen in Figures 19 to 22. In a group A of three possible embodiments of the invention, the branches of the two U-20 frames and 21, the protrusions of the semi-floats 22 and 26, and the pairs of holes 23, 24, 25, 27, 28, 29, are located on the inner sides of the semi-floats 6 and 7. With this arrangement, the branches of the frames in U 20 and 21, and therefore the elements listed above that allow their accommodation and horizontal displacement, can be at different height, with two different horizontal sliding planes for the two U-frames 20 and 21 (in the case of the embodiments A1 and
A2), o a Ia misma altura, con un único plano de deslizamiento horizontal para ambos bastidores 20 y 21 (caso de Ia forma de realización A3). En este último, las ramas de los bastidores en U 20 y 21 acaban en extremos tubulares que permiten su introducción y encaje mutuo. Para ello los salientes de los semiflotadores 22 y 26 y los pares de agujeros longitudinales 23, 24, 25, 27, 28 y 29 se encuentran a Ia misma altura, con Ia particularidad de que los pares de agujeros 24 y 29 y los pares de agujeros 25 y 28 son los mismos al coincidir en el mismo plano. En un grupo B de tres realizaciones posibles de Ia invención, las ramas de los dos bastidores en U 20 y 21, los salientes de los semiflotadores 22 y 26, y los pares de agujeros 23, 24, 25, 27, 28, 29, se encuentran en los lados exteriores de los semiflotadores 6 y 7. Con esta disposición, las ramas de los bastidores en U 20 y 21, y por tanto los elementos anteriormente enumerados que permiten su alojamiento y desplazamiento horizontal, pueden estara diferente altura, con dos planos de deslizamiento horizontales distintos para los dos bastidores en U 20 y 21 (caso de las formas de realización B1 y B2), o a Ia misma altura, con un único plano de deslizamiento horizontal para ambos bastidores 20 y 21 (caso de Ia forma de realización B3). En este último, las ramas de los bastidores en U 20 y 21 acaban en extremos tubulares que permiten su introducción y encaje mutuo. Para ello los salientes de los semiflotadores 22 y 26 y los pares de agujeros longitudinales 23, 24, 25, 27, 28 y 29 se encuentran a Ia misma altura, con Ia particularidad de que los pares de agujeros 24 y 29 y los pares de agujeros 25 y 28 son los mismos al coincidir en el mismo plano. En un grupo C de una única realización posible de Ia invención C1, las ramas de los dos bastidores en U 20 y 21 se encuentran en el mismo plano de deslizamiento horizontal, desplazándose ambos sobre ranuras y agujeros practicados alineada y horizontalmente en Ia parte superior de los semiflotadores 6 y 7, a Io largo de su plano de simetría longitudinal vertical, y por debajo de los tubos 9 y 10 de Ia bisagra del patín acuático, puesto que de pasar por arriba de ésta el patín no podría plegarse, y tampoco pueden atravesar Ia barra del propio eje de Ia bisagra de plegado. Los salientes de los semiflotadores 22 y 26, y los pares de agujeros y ranuras 23, 24, 25, 27, 28 y 29 se encuentran todos a Ia misma altura y alineados en cada uno de los lados de Ia embarcación (derecho e izquierdo), a Io largo del plano de simetría longitudinal vertical de cada uno de los semiflotadores 6 y 7. Los extremos de los bastidores en U 20 y 21 acaban en extremos huecos o macizos rebajados, como en Ia forma de realización A3, de forma que cada extremo se encaja y embute en el del bastidor contrario para formar en conjunto un bastidor rectangular exteπsible y desplazable. Al haber un único plano de deslizamiento, al igual que en Ia realización A3, los pares de agujeros 24 y 29 y los pares de agujeros 25 y 28 son también los mismos en esta realización.A2), or at the same height, with a single horizontal slide plane for both frames 20 and 21 (case of embodiment A3). In the latter, the branches of the U-frames 20 and 21 end in tubular ends that allow their introduction and mutual fit. For this, the protrusions of the semi-floats 22 and 26 and the pairs of longitudinal holes 23, 24, 25, 27, 28 and 29 are at the same height, with the particularity that the pairs of holes 24 and 29 and the pairs of holes 25 and 28 are the same when they coincide in the same plane. In a group B of three possible embodiments of the invention, the branches of the two U-frames 20 and 21, the projections of the semi-floats 22 and 26, and the pairs of holes 23, 24, 25, 27, 28, 29, They are located on the outer sides of the semi-floats 6 and 7. With this arrangement, the branches of the U-frames 20 and 21, and therefore the elements listed above that allow their accommodation and horizontal displacement, can be different height, with two different horizontal sliding planes for the two U-frames 20 and 21 (case of embodiments B1 and B2), or at the same height, with a single horizontal sliding plane for both frames 20 and 21 (case of the shape of embodiment B3). In the latter, the branches of the U-frames 20 and 21 end in tubular ends that allow their introduction and mutual fit. For this, the protrusions of the semi-floats 22 and 26 and the pairs of longitudinal holes 23, 24, 25, 27, 28 and 29 are at the same height, with the particularity that the pairs of holes 24 and 29 and the pairs of holes 25 and 28 are the same when they coincide in the same plane. In a group C of a single possible embodiment of the invention C1, the branches of the two U-frames 20 and 21 are in the same plane of horizontal sliding, both moving on grooves and holes practiced aligned and horizontally in the upper part of the semi-floats 6 and 7, along its plane of vertical longitudinal symmetry, and below the tubes 9 and 10 of the hinge of the water skate, since if it passes above it, the skate could not be folded, nor can they cross the bar of the axis of the folding hinge itself. The protrusions of the semi-floats 22 and 26, and the pairs of holes and grooves 23, 24, 25, 27, 28 and 29 are all at the same height and aligned on each side of the vessel (right and left), along the vertical longitudinal symmetry plane of each of the semi-floats 6 and 7. The ends of the U-frames 20 and 21 end at hollow or solid-cut ends, as in the embodiment A3, so that each end is fitted and embedded in that of the opposite frame to together form an extendable and movable rectangular frame. Since there is a single slide plane, as in the A3 embodiment, the pairs of holes 24 and 29 and the pairs of holes 25 and 28 are also the same in this embodiment.
En un grupo D de dos realizaciones posibles de Ia invención D1 y D2, los dos bastidores en U 20 y 21 se deslizan en un mismo plano de deslizamiento horizontal en ranuras y agujeros longitudinales practicadas en Ia parte superior de los semiflotadores 6 y 7, como en Ia realización C1, pero en este caso los extremos de tales bastidores no se embuten mutuamente, con Io que los pares de agujeros 23, 24 y 25 están alineados entre sí en cada lado de Ia embarcación, pero no con los pares de agujeros 27, 28 y 29, y ambos bastidores tienen diferentes anchuras. En Ia forma de realización D1 el bastidor en U trasero 21 es más ancho que el bastidor delantero en U20, y en Ia forma de realización D2 sucede Io contrario.In a group D of two possible embodiments of the invention D1 and D2, the two U-frames 20 and 21 slide in the same horizontal sliding plane in grooves and longitudinal holes made in the upper part of the semi-floats 6 and 7, as in the embodiment C1, but in this case the ends of such frames are not mutually inlaid, so that the pairs of holes 23, 24 and 25 are aligned with each other on each side of the vessel, but not with the pairs of holes 27 , 28 and 29, and both frames have different widths. In the embodiment D1 the rear U-frame 21 is wider than the front frame in U20, and in the embodiment D2 the opposite occurs.
Las formas de realización C y D tienen el inconveniente de eliminar los cajones laterales 59 y sus tapas reposabrazos 60, ya que las barras de los bastidores en U 20 y 21 invaden el espacio destinado a los cajones, y los huecos 64 donde se embuten las tapas de los mismos.Embodiments C and D have the disadvantage of eliminating the side drawers 59 and their armrest covers 60, since the bars of the U-frames 20 and 21 invade the space destined for the drawers, and the gaps 64 where the caps of them.
El requisito para que Ia embarcación no se pliegue es que cada uno de los agujeros de los pares de agujeros 24 y 25, y 28 y 29, estén alineados entre sí para permitir el encaje de los extremos de los bastidores en U 20 y 21. En las formas de realización A1, A2, A3, B1, B2, y B3 las ramas de los dos bastidores en U 20 y 21 son rectas, de forma que en cada lado de Ia embarcación los agujeros 23, 24 y 25 están alineados entre sí, así como los agujeros 27, 28 y 29.The requirement for the boat not to fold is that each of the holes in the pairs of holes 24 and 25, and 28 and 29, are aligned with each other to allow the fit of the ends of the U-frames 20 and 21. In the ways of embodiment A1, A2, A3, B1, B2, and B3 the branches of the two U-frames 20 and 21 are straight, so that on each side of the vessel the holes 23, 24 and 25 are aligned with each other, as well as holes 27, 28 and 29.
Otras formas de realización de Ia invención A1\ A2\ A3', B1', B2', B3', se diferencian de las anteriores en que los bastidores en U tienen en sus ramas curvadas en sentido vertical y / o horizontal, de forma que los pares de agujeros 23 no estén alineados con los pares de agujeros 24 y 25 y / o los pares de agujeros 27 no estén alineados con los pares de agujeros 28 y 29. Estas curvas pueden servir de tope del bastidor delantero en U 20 contra los salientes 22 de los sem ¡flotadores delanteros 6, para que éste no se salga de su sitio, y de tope del bastidor trasero en U 21 contra los salientes 26 de los semiflotadores traseros 7, para que éste tampoco se salga de su sitio, pero de forma que se permite en Ia posición de estos topes el plegado de Ia estructura del patín acuático, de forma que Ia única manera de extraer el bastidor es desatornillando o desmontando los pares de salientes 22 y 26, que forzosamente deben estar entonces fabricados en una piezas separables de las plataformas de flotación.Other embodiments of the invention A1 \ A2 \ A3 ', B1', B2 ', B3', differ from the previous ones in that the U-frames have curved branches vertically and / or horizontally, so that the pairs of holes 23 are not aligned with the pairs of holes 24 and 25 and / or the pairs of holes 27 are not aligned with the pairs of holes 28 and 29. These curves can serve as a stop of the front frame at U 20 against the projections 22 of the front half-floats 6, so that the latter does not leave its place, and abutment of the rear U-frame 21 against the projections 26 of the rear semi-floats 7, so that it does not leave its place, but so that in the position of these stops the folding of the structure of the water skate is allowed, so that the only way to remove the frame is by unscrewing or disassembling the pairs of projections 22 and 26, which must necessarily be manufactured in a separable parts of the pl flotation ataformas.
Pueden realizarse asimismo combinaciones mixtas, en los que Ia disposición de elementos de las plataformas de flotación delantera 1 y trasera 2, y los bastidores en U delantero 20 y trasero 21 siguen dos formas de realización distintas, asegurándose el anclaje de Ia estructura de flotación, aunque complicando y encareciendo el producto. Es posible combinar entre sí de dos en dos, aplicándolas a las plataformas de flotación delantera 1 y trasera 2, aquellas realizaciones en que los extremos de los bastidores en U no se embuten mutuamente, es decir las realizaciones A1, A2, B1, B2, D1, D2, A1 ', A2', B1', B2', DT, D2', Io cual da un gran número de combinaciones posibles. Ya indicamos anteriormente que podía haber uno o dos pares de agujerosMixed combinations can also be made, in which the arrangement of elements of the front and rear flotation platforms 2, and the front and rear U-frames 20 follow two different embodiments, ensuring the anchoring of the flotation structure, although complicating and making the product more expensive. It is possible to combine with each other two by two, applying them to the front 1 and rear 2 flotation platforms, those embodiments in which the ends of the U-frames are not mutually inlaid, that is, embodiments A1, A2, B1, B2, D1, D2, A1 ', A2', B1 ', B2', DT, D2 ', which gives a large number of possible combinations. We already indicated earlier that there could be one or two pairs of holes
25 paralelos entre sí, y uno o dos pares de agujeros 29 paralelos entre sí. En las combinaciones mixtas anteriores de plataformas de flotación distintas se precisa de dos pares de agujeros 25 y dos pares de agujeros 29 paralelos para alojar las ramas de dos bastidores de diferente anchura y / o altura. 25 parallel to each other, and one or two pairs of holes 29 parallel to each other. In the previous mixed combinations of different flotation platforms, two pairs of holes 25 and two pairs of parallel holes 29 are required to accommodate the branches of two frames of different width and / or height.
