Tacón para calzado.Heel for footwear.

Object of the invention

La presente invención, tal y como se expresa en el enunciado de esta memoria descriptiva, se refiere a un tacón para calzado cuya finalidad es proporcionar un tacón alto en calzados de mujer, de los que presentan una parte fija y otra móvil respecto de la anterior para mejorar la comodidad al caminar con estos calzados de tacón alto, de manera que el tacón presente una zona de compresión y expansión, con lo que al efectuar la correspondiente pisada se produce una compresión, mientras que al dejar de ejercer la pisada se recupera la longitud natural del tacón. Es objeto de la invención el mejorar inconvenientes que se dan en los tacones existentes de este tipo, tales como ruidos, facilidad de deterioro en la correspondiente estructura del tacón, excesivas fricciones en los laterales del tacón y dificultad en el recambio o variación de la resistencia de los correspondientes medios elásticos en función del peso de la usuaria.The present invention, as expressed in the statement of this specification refers to a heel for footwear whose purpose is to provide a high heel in women's shoes, of which they have a fixed and a mobile part compared to the previous one to improve comfort when walking with these high-heeled shoes, so that the heel presents a area of compression and expansion, so when performing the corresponding tread compression occurs while stop exercising the footprint recovers the natural length of the heel. It is an object of the invention to improve disadvantages that they give in existing heels of this type, such as noise, ease of deterioration in the corresponding heel structure, excessive friction on the sides of the heel and difficulty in the replacement or variation of the corresponding resistance elastic means depending on the weight of the user.

Background of the invention

Son conocidos los inconvenientes que se dan en calzados de tacón alto, tales como dolor de pies, piernas cargadas, dolores de espalda, riesgos de caída u otros. Para solventar esos inconvenientes y mejorar la comodidad de la pisada en zapatos de tacón alto sin perjudicar la estética que proporciona el calzado de tacón alto se han realizado tacones para calzado de altura variable, tales como el descrito en el Modelo de Utilidad 200702131. Estos tacones de altura variable conocidos presentan una parte superior unida a la parte inferior trasera del zapato y relacionada de manera guiada y a través de medios elásticos con una parte inferior del tacón, quedando entre esas partes una zona de compresión y expansión que se comprime disminuyendo la altura del tacón en la correspondiente pisada y que se expande al dejar de ejercer la fuerza de la pisada. Estos tacones de altura variable convencionales presentan inconvenientes relativos a que los referidos medios elásticos están determinados por unos resortes que producen ruidos molestos en los movimientos de compresión y de expansión, y además las estructuras facilitadas por estos tacones de altura variable conocidos carecen de la estabilidad y resistencia que serían deseables, produciéndose excesivas fricciones laterales en el tacón. Otro inconveniente de los tacones convencionales de este tipo consiste en el relativamente elevado coste de cambiar la resistencia de los correspondientes medios elásticos para adaptación a distintos pesos de
usuarias.The inconveniences that occur in high-heeled shoes, such as foot pain, loaded legs, backaches, fall hazards or others are known. To solve these inconveniences and improve the comfort of the tread in high heels without damaging the aesthetics provided by high-heeled shoes, heels have been made for shoes of varying height, such as the one described in the Utility Model 200702131. These heels of known variable height have an upper part attached to the lower rear part of the shoe and related in a guided manner and through elastic means with a lower part of the heel, being between those parts a compression and expansion zone that is compressed by decreasing the height of the heel in the corresponding tread and that expands when you stop exercising the force of the tread. These conventional variable height heels have drawbacks related to the fact that the said elastic means are determined by springs that produce annoying noise in the compression and expansion movements, and also the structures provided by these known variable height heels lack the stability and resistance that would be desirable, producing excessive lateral friction in the heel. Another drawback of conventional heels of this type is the relatively high cost of changing the resistance of the corresponding elastic means for adaptation to different weights of
users.

No conocemos en el estado actual de la técnica ningún tacón para calzado de altura variable que se constituya tal y como lo hace el de la presente invención.We do not know in the current state of the art no heel for footwear of variable height that constitutes such and as does that of the present invention.
