Suela para calzado de seguridad y calzado provisto de la mismaSole for safety footwear and footwear provided therewith

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION

La presente solicitud tiene por objeto el registro de una suela para calzado de seguridad, así como un calzado provisto de dicha suela.The purpose of this application is to register a sole for safety footwear, as well as footwear provided with said sole.

Más concretamente, la invención propone el desarrollo de una suela que cumple satisfactoriamente con la ergonomía y las propiedades de seguridad.More specifically, the invention proposes the development of a sole that satisfactorily meets ergonomics and safety properties.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Como es bien sabido, en la industria del calzado se tiende, por un lado, a fabricar un calzado cada vez más cómodo y, al mismo tiempo, con mayores prestacionesAs is well known, in the footwear industry there is a tendency, on the one hand, to manufacture increasingly comfortable footwear and, at the same time, with better features.

Existen sectores en los que se requiere que la utilización de un calzado de seguridad por parte de los trabajadores a fin de cumplir con determinadas condiciones de seguridad.There are sectors in which the use of safety footwear by workers is required in order to comply with certain safety conditions.

En principio, al hablar de calzado de seguridad se suele identificar con un calzado para proteger a los trabajadores de los riesgos que pueden encontrarse en el medio laboral, pensando como tal en un entorno industrial o bien aquellos grupos que corresponden a cuerpos de seguridad o emergencias, estando el calzado provisto de al menos una capa inferior o base y una capa hecha de un material con propiedades antiperforantes.In principle, when talking about safety footwear, it is usually identified with footwear to protect workers from the risks that can be found in the workplace, thinking as such in an industrial environment or those groups that correspond to security forces or emergencies. , the footwear being provided with at least a bottom or base layer and a layer made of a material with anti-perforation properties.

No obstante, se ha detectado un inconveniente en este tipo de calzado debido a que la estructura que lo conforma está centrada esencialmente en las características de seguridad, descuidando las relativas al confort, por lo que con el transcurso del tiempo durante una jornada laboral puede resulta un calzado que aumenta la fatiga en la zona de los pies del usuario.However, a drawback has been detected in this type of footwear due to the fact that the structure that makes it up is essentially focused on safety features, neglecting those related to comfort, so that over time during a working day it can become a shoe that increases fatigue in the area of the user's feet.

Estas molestias pueden generar problemas de salud como por ejemplo una fascitis plantar u otras patologías, por lo que existe la necesidad de encontrar una suela para calzado de seguridad que no solamente cumpla con los requisitos de protección, sino que además sea cómodo para el usuario.These discomforts can cause health problems such as plantar fasciitis or other pathologies, which is why there is a need to find a sole for footwear of security that not only meets the protection requirements, but is also comfortable for the user.

Además, el solicitante no tiene conocimiento en la actualidad de una invención que disponga de todas las características que se describen en esta memoria.In addition, the applicant is not currently aware of an invention that has all the characteristics that are described in this specification.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

La presente invención se ha desarrollado con el fin de proporcionar una suela para calzado de seguridad que se configura como una novedad dentro del campo de aplicación y resuelve los inconvenientes anteriormente mencionados, aportando, además, otras ventajas adicionales que serán evidentes a partir de la descripción que se acompaña a continuación.The present invention has been developed in order to provide a sole for safety footwear that is configured as a novelty within the field of application and solves the aforementioned drawbacks, also providing other additional advantages that will be evident from the description. which is attached below.

Es por lo tanto un objeto de la presente invención proporcionar una suela para calzado de seguridad, del tipo que comprende un cuerpo monobloque provisto de una capa inferior, hecha por ejemplo, a partir de material termoplástico inyectado, con propiedades antideslizantes apta para el contacto con el suelo que define un alojamiento. En particular, la invención se caracteriza por el hecho de que incluye una capa superior situada en el alojamiento de la capa inferior, que es apta para entrar en contacto con el pie del usuario, estando esta capa superior hecha de material espumado y una capa intermedia con propiedades antiperforantes interpuesta entre la capa superior e inferior que está hecha de material textil no tejido a partir de la disposición entrelazada de múltiples fibras de alta tenacidad.It is therefore an object of the present invention to provide a sole for safety footwear, of the type comprising a monobloc body provided with a lower layer, made for example from injected thermoplastic material, with non-slip properties suitable for contact with the floor that defines an accommodation. In particular, the invention is characterized by the fact that it includes an upper layer located in the housing of the lower layer, which is suitable for coming into contact with the user's foot, this upper layer being made of foamed material, and an intermediate layer with anti-perforation properties interposed between the upper and lower layer that is made of non-woven fabric from the interlaced arrangement of multiple high-tenacity fibers.

Preferentemente, la capa superior está hecha de poliuretano, mientras que las fibras de la capa intermedia pueden ser de kevlar®.Preferably, the upper layer is made of polyurethane, while the fibers of the intermediate layer can be made of kevlar®.

Ventajosamente, para mejorar la ergonomía, la capa superior presenta un espesor no uniforme que tiene un decrecimiento del espesor en la dirección desde la zona del talón hacia la zona de la puntera.Advantageously, in order to improve ergonomics, the upper layer has a non-uniform thickness that decreases in thickness in the direction from the heel area towards the toe area.

Gracias a esta disposición específica de las distintas capas que conforman la suela, la pisada recae directamente sobre la capa espumada, mejorando así la ergonomía y comodidad de un calzado provisto de dicha suela, lo que implica también generar un menor cansancio y menor desgaste muscular y óseo de los pies del usuario. Thanks to this specific arrangement of the different layers that make up the sole, the footprint falls directly on the foamed layer, thus improving the ergonomics and comfort of footwear equipped with said sole, which also implies less fatigue and less muscle wear and tear. bone of the user's feet.

Es también otro objeto de la invención proporcionar un calzado que comprende un corte adherido a una suela como la descrita anteriormente.It is also another object of the invention to provide footwear comprising an upper adhered to a sole as described above.

La suela para calzado de seguridad descrita representa, pues, una estructura innovadora de características estructurales y constitutivas desconocidas hasta ahora para el fin a que se destina, razones que unidas a su utilidad práctica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita.The described sole for safety footwear represents, therefore, an innovative structure with structural and constitutive characteristics unknown until now for the purpose for which it is intended, reasons that, together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity that is requested.
