EXPOSICIÓN DETALLADA DE LA REALIZACIÓN PREFERENTE DE LA INVENCIÓN DETAILED EXHIBITION OF THE PREFERRED EMBODIMENT OF THE INVENTION
La presente invención es una suela para calzado que comprende una cama (1) de poliuretano y un colchón (2) de poliuretano, en la que la densidad de la cama (1) es mayor que la densidad del colchón (2) . The present invention is a sole for footwear comprising a bed (1) of polyurethane and a mattress (2) of polyurethane, in which the density of the bed (1) is greater than the density of the mattress (2).
En esta descripción de suela se utiliza el término "cama" para referirse a las configuraciones conocidas cuya forma incluye una cavidad en la parte superior, la opuesta al suelo, que alberga la otra parte de la suela, conocida como "colchón". Esta "cama" también es mencionada en la técnica como "cuna" y "bar¬ co", y en inglés como "foot bed" . In this sole description, the term "bed" is used to refer to known configurations whose shape includes a cavity in the upper part, the opposite of the floor, which houses the other part of the sole, known as "mattress". This "bed" is also mentioned in the art as "cot" and "bar ¬ co", and in English as "foot bed".
La densidad del poliuretano del colchón (2) hace que éste sea muy ligero en relación con la cama (1), además este material tiene memoria de forma y recupera¬ ción con lo que cumple su principal función que es aportar comodidad en la pisada. The density polyurethane mattress (2) makes this very light in relation to the bed (1), also this material has shape memory and retrieves ¬ thus fulfills its main function is to provide comfort in the tread.
En la realización más simple y general de esta realización, la cama (1) presenta distribuidas en su superficie interior (1.1) protuberancias (1.3). Éstas son configuraciones que se extienden como volúmenes que se proyectan a partir de la superficie principal en cuestión . In the simplest and most general embodiment of this embodiment, the bed (1) has protrusions (1.3) distributed on its inner surface (1.1). These are configurations that extend as volumes that are projected from the main surface in question.
En esta descripción, la denominación "interior" referido a las superficies de los elementos de la suela,
se refiere a la posición más cercana al pie. De la misma manera, la denominación "exterior" se refiere a la posición más cercana al suelo. In this description, the designation "interior" referred to the surfaces of the sole elements, It refers to the position closest to the foot. In the same way, the term "exterior" refers to the position closest to the ground.
De igual forma, el colchón (2) presenta configu¬ raciones huecas (2.3) distribuidas en su superficie exterior (2.2) en contacto con la cama (1) que se co¬ rresponden con las protuberancias (1.3). Similarly, the mattress (2) has hollow portions Configu ¬ (2.3) distributed over its outer surface (2.2) in contact with the bed (1) which co ¬ rresponden the protrusions (1.3).
Es decir, el colchón (2) presenta unas oquedades o configuraciones huecas (2.3) de la misma forma y dimensión que las protuberancias (1.3) de manera que las unas se corresponden perfectamente con las otras. That is, the mattress (2) has hollow holes or configurations (2.3) in the same shape and dimension as the protuberances (1.3) so that some correspond perfectly with the others.
La distribución de protuberancias (1.3) y confi¬ guraciones huecas (2.3) se lleva a cabo por las superfi¬ cies correspondientes, desde un mínimo de dos hasta tantas como quepan físicamente en dichas superficies. The distribution of protuberances (1.3) and confi guration ¬ hollow (2.3) is carried out by superfi ¬ corresponding surfaces, from a minimum of two to as many as physically fit on said surfaces.
Las protuberancias (1.3) y configuraciones hue¬ cas (2.3) se pueden distribuir bien en zonas concretas de la suela, tacón y puntera por ejemplo, según el tipo de calzado. The protrusions (1.3) and hue settings ¬ cas (2.3) can be distributed well in specific areas of the sole, heel and toe for example, depending on the type of footwear.
De todas formas, con el fin de conseguir un efecto masajeante o que ayude a activar la circulación sanguínea en el pie, las protuberancias (1.3) y configu¬ raciones huecas (2.3) se colocan distribuidas por todas las superficies correspondientes de la suela según estudios biomecánicos, consiguiendo así suelas anatómi¬ cas, conocidas en ortopedia como plantillas "fakir". However, in order to achieve a massaging effect or help activate blood circulation in the foot, the projections (1.3) and Configu ¬ hollow portions (2.3) are placed distributed over all corresponding surfaces of the sole according studies biomechanical and Anatomical soles getting ¬ cas, known in orthopedics as templates "fakir".
Las dimensiones de las protuberancias (1.3) y configuraciones huecas (2.3) dependen de cada caso y según se busque dureza, amortiguación, flexibilidad,
etc. Así, cada necesidad necesita unas dimensiones así como diferentes espesores de la cama (1) y del colchón (2) . The dimensions of the protuberances (1.3) and hollow configurations (2.3) depend on each case and according to hardness, damping, flexibility, etc. Thus, each need needs dimensions as well as different thicknesses of the bed (1) and the mattress (2).
Los diferentes usos mencionados hacen que en unas ocasiones unos tipos geométricos sean más adecuados que otros y que incluso puedan combinarse entre sí dentro de una misma suela. The different uses mentioned sometimes make some geometric types more suitable than others and can even be combined with each other within the same sole.
Así, las protuberancias (1.3) y las configura¬ ciones huecas (2.3) son troncos de pirámide con la base mayor por debajo de la base menor en una variante de la realización mencionada. Thus, the protrusions (1.3) and configured hollow ¬ tions (2.3) are truncated pyramids with the larger base below the smaller base in a variant of the embodiment mentioned.
0 bien, las protuberancias (1.3) y las configu¬ raciones huecas (2.3) son troncos de conos con la base mayor por debajo de la base menor. 0 well, the protrusions (1.3) and Configu ¬ hollow portions (2.3) are truncated cones with the greater base below the smaller base.
También, las protuberancias (1.3) y las configu¬ raciones huecas (2.3) son prismas, o bien son cilindros. Also, the protrusions (1.3) and Configu ¬ hollow portions (2.3) are prisms or cylinders are.
E incluso se demuestra la utilidad en diferentes ensayos de que las protuberancias (1.3) y las configura¬ ciones huecas (2.3) son semiesferas. And even utility is demonstrated in the different assays that the protrusions (1.3) and configured hollow ¬ tions (2.3) are hemispheres.
Como se ha mencionado más arriba, una realiza¬ ción preferida es en la que todas las protuberancias (1.3) y todas las configuraciones huecas (2.3) de una misma suela son iguales. As mentioned above, one performs ¬ tion is preferred in that all protrusions (1.3) and all configurations hollow (2.3) of the same sole are equal.
Las características expuestas se ven mejoradas si además de la comodidad que proporcionan los dos poliuretanos de diferente densidad se añade un colchón de gas entre ambos. De esta forma, se puede decir que hay tres métodos para aportar comodidad en la pisada: un
poliuretano de relativa baja densidad, un colchón de gas y un poliuretano de mayor densidad que el anterior. The exposed characteristics are improved if, in addition to the comfort provided by the two polyurethanes of different density, a gas mattress is added between them. In this way, it can be said that there are three methods to provide comfort in the tread: a Relatively low density polyurethane, a gas mattress and a higher density polyurethane than the previous one.
El colchón de gas se crea en el curado del po¬ liuretano, ya que la reacción química provoca gas, y se sitúa entre el extremo superior de una protuberanciaThe gas cushion is created in the curing of po ¬ liuretano, since the chemical reaction causes gas, and is between the top end of a protrusion
(1.3) y su correspondiente configuración hueca (2.3) en una cámara de gas (3), en la que dicho gas queda atrapa¬ do entre la cama (1) y el colchón (2) . (1.3) and its hollow configuration (2.3) in a gas chamber (3), wherein said gas is trapped between the bed do ¬ (1) and mattress (2).
Una configuración preferente de la cámara de gas (3) que se ha comprobado de óptimo funcionamiento es una esfera cuyo estrechamiento que la une a la correspon¬ diente configuración hueca (2.3) permite el paso del gas pero no del poliuretano. A preferred embodiment of the gas chamber (3) which has been found optimal operation is a sphere whose narrowing that joins the tooth correspon ¬ hollow configuration (2.3) allows the passage of gas but not of the polyurethane.
Entre cámaras de gas puede haber conductos que las comuniquen, no mostrados en las figuras, de manera que permiten el paso de gas de unas a otras, por ejem¬ plo, de la zona de la puntera al talón y viceversa, ayudando en el rodaje de la pisada y la comodidad gene¬ ral del calzado. Between gas chamber may have passages that communicate, not shown in the figures, so as to allow the passage of gas from one to another, EG ¬ plo, the forefoot area to the heel and vice versa, helping in the shooting tread and gene ¬ ral comfort footwear.
En correspondencia, según un plano vertical co¬ incidente con el plano longitudinal de las protuberan¬ cias (1.3) y las configuraciones huecas (2.3), en la superficie interior (2.1) del colchón (2) en contacto con el pie se disponen configuraciones semiesféricasCorrespondingly, a vertical plane co ¬ incident with the longitudinal plane of protuberan ¬ ences (1.3) and hollow configurations (2.3), on the inner surface (2.1) of the mattress (2) in contact with the foot configurations are arranged hemispherical
(2.4) con la base en dicha superficie interior (2.1) del colchón ( 2 ) . (2.4) with the base on said inner surface (2.1) of the mattress (2).
Estas configuraciones se suelen utilizar en los casos en que el espesor total de la suela sea pequeño, ya que contribuyen a la comodidad general aun con dimen¬ siones de altura de la semiesfera, es decir el radio, de
aproximadamente 1mm. These settings are usually used in cases where the total thickness of the sole is small, contributing to the overall comfort even with dimen ¬ sions height of the hemisphere, ie the radio, about 1mm
Por ello, estas configuraciones semiesféricas (2.4) pueden aportar amortiguación en la pisada, lo cual se mejora añadiendo una ranura (2.5) que rodea su base de manera que se mejora el funcionamiento elástico de estas configuraciones, a modo de superficies flotantes. Therefore, these hemispherical configurations (2.4) can provide damping in the tread, which is improved by adding a groove (2.5) that surrounds its base so that the elastic performance of these configurations is improved, as a floating surface.
Otra mejora en la aportación de efectos benefi¬ ciosos en la suela viene dada por la inclusión de ele¬ mentos electromagnéticos cuyo campo contribuye a incrementar los beneficios mencionados de masaje y activación. Asi, entre la cama (1) y el colchón (2) se dispone al menos un imán permanente (4) que se alberga en la correspondiente configuración hueca (2.3) del colchón ( 2 ) . Another improvement in providing ¬ benefi cial effects in the sole is given by the inclusion of ele ments ¬ electromagnetic field which contributes to increase the benefits mentioned massage and activation. Thus, between the bed (1) and the mattress (2) there is at least one permanent magnet (4) that is housed in the corresponding hollow configuration (2.3) of the mattress (2).
Con el fin de preservar la cama del desgaste por el uso y mejorar la adherencia de toda la suela en la pisada, además la suela comprende una lámina (5) de poliuretano antideslizante dispuesta en la superficie exterior (1.2) de la cama (1) de manera que la superfi¬ cie exterior (5.2) de dicha lámina está en contacto con el suelo. In order to preserve the bed from wear and tear and improve the adhesion of the entire sole in the tread, the sole also comprises a sheet (5) of non-slip polyurethane arranged on the outer surface (1.2) of the bed (1) so that the outer superfi ¬ surface (5.2) of said sheet is in contact with the ground.
El procedimiento de fabricación de una suela de calzado según se ha descrito comprende las siguientes etapas : The manufacturing process of a shoe sole as described comprises the following steps:
-colocación del colchón (2) de la suela ya formado en la tapa del molde; -placing the mattress (2) of the sole already formed in the mold cover;
-introducción del poliuretano de la cama (1) por colada en el molde; -introduction of the bed polyurethane (1) by casting in the mold;
-cierre del molde; -Closure of the mold;
-curado del poliuretano de la cama (1) envol¬ viendo al colchón (2);
-apertura del molde; - Polyurethane bed curing (1) wrapping ¬ looking at the mattress (2); -open the mold;
-retirada de la suela. -removal of the sole.
Cualquiera de las variantes mencionadas incluye estas etapas. Any of the variants mentioned include these stages.
En particular, cuando la suela incluye imanes (4), antes del cierre del molde se colocan éstos en el colchón (2) ya formado. In particular, when the sole includes magnets (4), before closing the mold they are placed on the mattress (2) already formed.
La sujeción del colchón (2) en el molde se lleva a cabo por métodos conocidos como vacio, agujas, pestaña periférica, etc., que aseguren la posición del mismo durante el colado y curado del poliuretano.
The fastening of the mattress (2) in the mold is carried out by methods known as vacuum, needles, peripheral flange, etc., which ensure its position during the casting and curing of the polyurethane.
