Description

CALZADO ERGONÓMICO ERGONOMIC FOOTWEAR
D E S C R I P C I Ó ND E S C R I P C I Ó N
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un calzado que ha sido concebido y estructurado en orden a conseguir para el mismo un alto grado de ergnomía, es decir, una óptima relación entre el calzado y el pie del usuario, especialmente a nivel de Ia puntera y el talón.The present invention relates to footwear that has been conceived and structured in order to achieve a high degree of ergnomy for it, that is, an optimal relationship between the footwear and the user's foot, especially at the level of the toe and the heel.
De forma más concreta, el objeto de Ia invención es conseguir un efecto amortiguador las partes extremas del calzado-, las destinadas a entrar en contacto con los dedos del pie y con el talón, que son las que se ven normalmente sometidas a impactos o roces, incrementando considerablemente el confort que dicho calzado ofrece al usuario en su uso al andar.More specifically, the object of the invention is to achieve a damping effect on the extreme parts of the footwear, those intended to come into contact with the toes and heel, which are those that are normally subjected to impacts or friction. , considerably increasing the comfort that said footwear offers to the user in its use when walking.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Como es sabido, en Ia estructuración de un calzado participa un corte, generalmente de piel, de naturaleza textil o de otro material apropiado, que se complementa interiormente con un forro, descansando éste último directamente sobre Ia superficie del pie.As it is known, in the structuring of a footwear a cut, generally of leather, of a textile nature or of another appropriate material, is involved, which is complemented internally with a lining, the latter resting directly on the surface of the foot.
Habitualmente, tanto para dar forma al calzado como para proteger las zonas extremas del pie de posibles agresiones exteriores, entre el corte y el forro se establece a nivel anterior del zapato un tope de un material rígido y a nivel del talón un contrafuerte de igual o similar naturaleza. Estos elementos, al tiempo que protegen el pie del exterior, someten tanto a los dedos como a los talones a un roce continuo, efecto que no es posible amortiguar con un simple forro.Usually, both to shape the footwear and to protect the extreme areas of the foot from possible external aggressions, between the cut and the lining a top of a rigid material is established at the level of the shoe and at the heel level a buttress of the same or similar nature. These elements, while protecting the foot from the outside, subject both the fingers and heels to a continuous friction, an effect that is not possible to cushion with a simple lining.
Con independencia de que habitualmente los forros se obtienen a base materiales baratos, al objeto de solventar el problema anteriormente citado, en ocasiones dichos forros incorporan una lámina esponjosα pαrα dar Ia sensación de amortiguación, pero este efecto desaparece rápidamente, y el contacto del pie se produce sobre el forro, que se deteriora al cabo de un período de tiempo relativamente corto, por los esfuerzos que sufre al andar y por el contacto y presión tanto de los dedos y uñas como del talón.Regardless of the fact that the liners are usually obtained based on cheap materials, in order to solve the aforementioned problem, sometimes these liners incorporate a sheet esponjosα pαrα give the sensation of damping, but this effect disappears quickly, and the contact of the foot is produced on the lining, which deteriorates after a relatively short period of time, due to the stresses that it suffers when walking and the contact and pressure of both fingers and toes and heel.
Esto no sólo supone un deterioro para el calzado, sino efectos negativos sobre los pies del ususario, con ennegrecimiento de las uñas, por Ia propia acción de las yemas de los dedos, agudizándose en aquellos que requieran acciones de frenado brusco, dado que los forros de pala no garantizan características de amortiguación como anteriormente se ha dicho. En tareas como Ia de conducir, se sufren especialmente estas deficiencias, donde el pie asume posturas para el control en los pedales y donde Ia mayor fuerza del pie recae sobre los dedos, que son los que realizan estos movimientos y por Io tanto se ven afectados por el constante rozamiento con el forro.This not only implies a deterioration for the footwear, but negative effects on the feet of the user, with blackening of the nails, by the very action of the fingertips, becoming more acute in those that require sudden braking actions, given that the linings Blade does not guarantee damping characteristics as previously stated. In tasks such as driving, these deficiencies are especially suffered, where the foot assumes positions for control on the pedals and where the greatest force of the foot rests on the fingers, which are those that perform these movements and therefore are affected by the constant friction with the lining.
La problemática anteriormente expuesta se acentúa cuando el calzado incorpora a nivel de Ia puntera casquillos metálicos protectores de golpes externos, determinantes de un altro grado de dureza en esta zona anterior del calzado.The aforementioned problem is accentuated when the footwear incorporates at the level of the toe cap metal bushings that are protective of external blows, determining a high degree of hardness in this anterior area of the footwear.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El calzado que Ia invención propone ha sido concebido en orden a resolver de forma plenamente satisfactoria Ia problemática anteriormente expuesta, incorporando medios de amortiguación y medios anti-choque tanto para los dedos y las uñas del pie como para Ia zona del talón, que son concretamente las zonas en las que, debido a Ia movilidad del pie al andar, se producen notables fricciones con el forro, ya que es en esta zona donde se produce el último contacto del pie con el suelo, en cada paso que se da al andar.The footwear that the invention proposes has been conceived in order to solve in a fully satisfactory manner the above-mentioned problem, incorporating damping means and anti-shock means both for the toes and toenails and for the heel area, which are specifically the areas in which, due to the mobility of the foot when walking, there are notable frictions with the lining, since it is in this area where the last contact of the foot with the ground occurs, in each step that occurs when walking.
Para ello y de forma más concreta, Ia invención consiste en sustituir tanto el tope delantero como el contrafuerte del calzado por respectivαs piezas b¡-dens¡dad, es decir, piezas con densidad muy diferente en su cara externa que en su cara interna, de manera que esta diferencia de densidad hace que Ia capa externa de tales piezas resulte dura y rígida, manteniendo Ia función clásica de estruca antideformación para el calzado y protección para el pie, mientras que Ia capa interna, con una menor densidad, determina un contacto suave y acolchado para el pie, obviamente a través del forro interior del mismo, aportando un alto grado de confort al calzado, que se mantiene inalterado a Io largo del tiempo.For this and more specifically, the invention consists in replacing both the front stop and the buttress of the footwear by respective b-density pieces, that is, pieces with very different density on their outer face than on their inner face, so that this difference in density makes the outer layer of such pieces hard and rigid, maintaining the function classic anti-deformation shoe structure and foot protection, while the inner layer, with a lower density, determines a soft and padded foot contact, obviously through the inner lining of the foot, providing a high degree of comfort to the footwear, which remains unchanged over time.
Se consigue de esta manera que todas las partes más sensibles del pie, especialmente las yemas de los dedos, se encuentren asistidas por materiales elásticos de alta densidad, con alta capacidad anti-choque, que eliminan Ia problemática convencional anteriormente expuesta.It is achieved in this way that all the most sensitive parts of the foot, especially the fingertips, are assisted by elastic materials of high density, with high anti-shock capacity, which eliminate the conventional problem described above.

PREFERRED EMBODIMENT OF THE INVENTION
A Ia vista de las figuras reseñadas, puede observarse como el calzado ergonómico que se preconiza está constituido, como cualquier calzado convencional, a partir de una suela (1 ), habitualmente recubierta por una plantilla interior (2), suela a cuyo perímetro se fija el corte (3), generalmente de piel, dotado de un forro o revestimiento interior (4).In view of the figures outlined, it can be seen how the ergonomic footwear that is recommended is constituted, like any conventional footwear, from a sole (1), usually covered by an interior insole (2), sole at whose perimeter it is fixed the cut (3), usually made of leather, provided with a lining or inner lining (4).
En principio, el calzado sería del tipo de los que entre el corte (3) y el forro (4) se sitúa a nivel de Ia puntera un tope y anivel del talón un contrafuerte, para dar Ia adecuada rigidez y protección a estas zonas del calzado, pero sin embargo y de acuerdo con Ia invención, tope y contrafuertes son sustituidos por respectivas piezas (5) y (6), de configuración y dimensiones similares al tope y contrafuerte a los que sustituyen, pero con Ia particularidad de que cada una de éstas piezas presenta características de bi-densidad, concretamente una capa externa (7) de mayor densidad, merced a Io que dicha capa resulta dura y rígida, cumpliendo Ia función clásica del tope o de contrafuerte de armar el calzado y proteger al pie de posibles impactos, y una capa interior (8) de densidad considerablemente menor, mucho más blanda y esponjosa, que es Ia que confiere al calzado el efecto amortiguador en las citadas zonas de Ia puntera.y el talón, incrementando de forma muy considerable tanto el confort del calzado como Ia vida útil del mismo, es decir potenciando de forma muy considerable Ia ergonomía en Ia normal utilización del calzado, concretamente haciendo que las partes tradicionalmente más duras del mismo, en Ia que habitualmente se producen los mayores daños sobre los pies, ofrezcan un contacto suave, blando y altamente confortable, sin menoscabo del efecto de armado para el corte del calzado y del efecto protector para los pies frente a agentes o impactos externos. In principle, the footwear would be of the type that between the cut (3) and the lining (4) is placed at the level of the toe cap and heel level a buttress, to give adequate rigidity and protection to these areas of the footwear, but nevertheless and according to the invention, stop and buttresses are replaced by respective pieces (5) and (6), of similar configuration and dimensions to the butt and buttress to those that replace, but with the particularity that each of these pieces it has bi-density characteristics, specifically an outer layer (7) of greater density, thanks to the fact that said layer is hard and rigid, fulfilling the classic function of the buttress or buttress of assembling the footwear and protecting the foot of possible impacts, and an inner layer (8) of considerably lower density, much softer and spongy, which is the one that gives the shoe the cushioning effect in the aforementioned areas of the toe and heel, increasing in a very considerable way both the comfort of the footwear and its useful life, that is to say, greatly enhancing the ergonomics in the normal use of the footwear, specifically making the traditionally tougher parts of it, in which the greatest damage usually occurs on the feet, offer a soft, soft and highly comfortable contact, without prejudice to the effect of arming for the cut of the footwear and the protective effect for the feet against agents or external impacts.
