Mucha gente cree que los patinadores sobre hielo usan cuchillas porque, al ser muy delgadas se reduce el rozamiento pudiendo así deslizarse por el hielo. La verdad es que el rozamiento que sufren los patinadores sólo depende de su peso y de un numerito llamado coeficiente de rozamiento que depende únicamente del hielo y el tipo de metal. Por este motivo daría igual que patinaran sobre una cuchilla o sobre una plancha de metal pues el rozamiento es el mismo. La explicación que se da se encuentra basada en una fórmula que expresa que la temperatura a la que el hielo se funde depende de la presión que sufre de forma que cuanta más presión sufre el hielo menor es su temperatura de fusión y antes se funde. Pero eso no es así porque lo que en realidad ocurre es que el hielo se funde por fricción y no por presión. Además el uso de cuchillas está indicado para facilitar los giros. Many people believe that ice skaters use blades because, because they are very thin, friction is reduced and can slide through the ice. The truth is that the friction suffered by skaters only depends on their weight and a number called friction coefficient that depends solely on ice and the type of metal. For this reason it would not matter if they skated on a blade or on a metal plate because the friction is the same. The explanation given is based on a formula that expresses that the temperature at which the ice melts depends on the pressure it suffers so that the more pressure the ice suffers, the lower its melting temperature is and before it melts. But that is not so because what actually happens is that the ice melts by friction and not by pressure. In addition the use of blades is indicated to facilitate the turns.
Se encuadra en la industria de las afiladoras de cuchillas y, dentro de ésta, de afiladoras para cuchillas de patinaje. ANTECEDENTES DE LA INVENCION It fits in the industry of the sharpeners of blades and, inside this one, of sharpeners for blades of skating. BACKGROUND OF THE INVENTION
Actualmente se conoce el documento 318391 que describe una afiladora convencional pero fijada al suelo por tres patas 203907 propone unas cuchillas afiladoras que mediante una palanca cambian el conjunto
formando espacios nuevos que periten la entrada de la cuchilla a afilar aunque sea de distinta forma. El documento ES1010122 narra tres piedras de esmerilas situadas formando un triangulo de modo que su base se encuentra ocupada por un empujador que acerca la pieza a afilar con una cuchilla dentada. Document 318391 is currently known, which describes a conventional sharpener but fixed to the ground by three legs. 203907 proposes sharpening blades that change the assembly using a lever. forming new spaces that allow the entrance of the blade to be sharpened even if it is in a different way. Document ES1010122 narrates three grinding stones located in a triangle so that its base is occupied by a pusher that approaches the piece to be sharpened with a serrated blade.
Esto que se conoce presenta los inconvenientes que a continuación se indican: This is known to have the following drawbacks:
- El documento 318391 posee el inconveniente de que no es transportable quedando fijado al suelo o bien moviéndose mediante acople de ruedas - Document 318391 has the disadvantage that it is not transportable being fixed to the ground or moving by means of wheel coupling
- El documento 203907 es más bien para afilar cuchillas pequeñas y de formas diferentes amén de sólo copilar una serie de formas y no todas las necesarias. - Document 203907 is rather for sharpening small and differently shaped blades in addition to only compiling a series of shapes and not all of them necessary.
- El documento ES1010122 tiene la desventaja de que se depende da las piedras esmeriladas para hacer cualquier afilado pudiendo fallar en cualquier momento. - Document ES1010122 has the disadvantage that it depends on the ground stones to make any sharpening and may fail at any time.
Frente a estos inconvenientes la invención propuesta presenta las siguientes ventajas: Faced with these drawbacks, the proposed invention has the following advantages:
No es una máquina de afilar fija al suelo y por tanto imposible de transportar. Al encontrarse compuesta de una base laminar e incorporar en su dorso las piedras y el piñón cremallera se convierte en una sola pieza solidaria que es fácil de manejar y, por tanto, de transportar.
No posee cambio de forma sino que son piedras de esmerilado que funcionan de una forma longitudinal y paralela a la cuchilla por lo que su sencillez le hace ser una máquina precisa para el afilado de cuchillas para patines. It is not a sharpening machine fixed to the ground and therefore impossible to transport. Being composed of a laminar base and incorporating the stones on the back and the rack and pinion becomes a single piece that is easy to handle and, therefore, to transport. It does not have a change of shape but they are grinding stones that work longitudinally and parallel to the blade so that its simplicity makes it an accurate machine for sharpening roller blades.
No depende de una estructura prefijada y unida mediante cintas capaz de romperse en un momento dado sino que se sostienen gracias a un resorte que mantiene las piedras en su lugar hasta que se conectan con la cuchilla donde el resorte salta y se posicionan exactamente en el lugar central de las cuchillas de los patines para afilarlos con certeza. It does not depend on a predetermined structure and joined by tapes capable of breaking at a given time but rather they are supported thanks to a spring that holds the stones in place until they connect with the blade where the spring jumps and is positioned exactly in place. center of the blades of the skates to sharpen them with certainty.
Requiere un mínimo de mantenimiento pues el conjunto es sencillo y solo consiste en un piñón y una cremallera amén de los brazos pivotantes y el resorte. It requires a minimum of maintenance because the assembly is simple and only consists of a pinion and a rack in addition to the pivoting arms and the spring.
Ahorra mucho tiempo porque las piedras efectúan solas el movimiento tanto de ida como de venida debido a la cremallera y al piñón. It saves a lot of time because the stones make the movement both back and forth due to the rack and pinion.
No hay peligro de que el usuario pueda cortarse o dañarse al encontrarse todo el conjunto en el dorso de la base que es el firme para los patines. There is no danger that the user can be cut or damaged when the whole assembly is found on the back of the base that is the skates firm.
Fácil de manejar pues consiste en activar el engranaje que traslada a las piedras esmeriles.
DESCRIPCION DE LA INVENCION Easy to handle because it consists of activating the gear that moves to the emerald stones. DESCRIPTION OF THE INVENTION
A modo de explicación de la invención, y para lograr los objetivos y evitar los inconvenientes indicados en anteriores apartados, la máquina afiladora de cuchilla de patines objeto de la presente invención se constituye a partir de una base de metal, donde se encuentran instaladas al menos dos láminas rígidas en cuya abertura se sitúa el patín y su cuchilla intercalándose esta última entre ambas laminas y sobresaliendo por el envés de la base fijándose el patín mediante tornillos y pieza de abrace que uniendo ambas láminas aseguran la posición de la cuchilla y por extensión del patín. El conjunto de las piedras de esmerilar consiste en; dos brazos pivotantes de forma que, mediante la acción de un resorte, existe la tendencia a mantenerse en posición elevada, por encima de las láminas de sujeción, pero que ante el encuentro con la cuchilla cede realizando un guiado mientras ejerce presión, que se usa para realizar el afilado. El avance longitudinal se produce por la acción de un conjunto piñón y cremallera y una pareja de carriles de circulación. Opcionalmente se incluye un perfil de apoyo cuya función es la de bajar la piedra por debajo de las láminas, con objeto de evitar que, en caso de una mala fijación o inexistencia del patín, el accionamiento del equipo provoque desperfectos en las láminas o en las piedras de afilado. By way of explanation of the invention, and to achieve the objectives and avoid the inconveniences indicated in previous sections, the roller blade sharpening machine object of the present invention is constituted from a metal base, where at least they are installed two rigid sheets in whose opening the skate and its blade are placed, the latter being inserted between the two sheets and protruding through the underside of the base, fixing the skate by means of screws and a clamp piece that joining both sheets ensures the position of the blade and by extension of the roller skate. The set of grinding stones consists of; two pivoting arms so that, by means of the action of a spring, there is a tendency to remain in an elevated position, above the clamping plates, but that when faced with the blade, it yields by guiding while exerting pressure, which is used to sharpen. The longitudinal advance is produced by the action of a rack and pinion assembly and a pair of traffic lanes. Optionally a support profile is included whose function is to lower the stone below the sheets, in order to avoid that, in case of a bad fixation or absence of the skate, the operation of the equipment causes damages in the sheets or in the sharpening stones
El funcionamiento comienza cuando el patín o los patines se insertan entre las ranuras existentes entre las láminas rígidas. Entonces se aprietan los tornillos que movilizan una pieza de abrace y ésta avanza
cerrando las láminas, fijando el patín por presión. Las piedras de esmerilado que se encuentran montadas sobre los brazos pivotantes se posicionan a una altura por encima del final de la cuchilla del patín por la acción que el resorte ejerce sobre aquellas. Al activar el funcionamiento del equipo las piedras comienzas a girar y el conjunto de piedras y brazos avanza sobre el carril de circulación en paralelo a la cuchilla del patín. El centro del perfil de las piedras de esmeril coincide con el centro de las cuchillas y cuando la piedra topa con las cuchillas el resorte cede amoldándose la posición de la piedra al perfil de la cuchilla afilándola. Una vez llegado al final de su recorrido lineal en donde se excede de la longitud del patín, la piedra comienza a desplazarse en la misma dirección pero en sentido contrario y vuelve a afilar la cuchilla. Operation begins when the skate or skates are inserted between the slots between the rigid sheets. Then the screws that mobilize a clamp piece are tightened and it advances closing the sheets, fixing the skate by pressure. The grinding stones that are mounted on the pivoting arms are positioned at a height above the end of the skate blade by the action that the spring exerts on them. When activating the operation of the equipment, the stones begin to rotate and the set of stones and arms advances on the circulation lane parallel to the skate blade. The center of the profile of the emery stones coincides with the center of the blades and when the stone meets the blades the spring yields by adjusting the position of the stone to the profile of the blade sharpening it. Once at the end of its linear path where the length of the skate is exceeded, the stone begins to move in the same direction but in the opposite direction and sharpens the blade again.
Opcionalmente, existe un contador de usos exterior, que ayuda al usuario a identificar el momento del cambio de piedra de afilado. Optionally, there is an external uses counter, which helps the user to identify the moment of the change of sharpening stone.
También opcionalmente se incluye un soporte para una piedra plana cuyo uso es el de eliminar rebabas laterales existentes en la cuchilla del patín tras su afilado. Optionally also includes a support for a flat stone whose use is to remove existing burrs on the blade of the skate after sharpening.
