Description

 SHOES WITH REMOVABLE HEEL

 TECHNICAL FIELD OF THE INVENTION The present invention relates to the technical field of mechanics, and specifically in the footwear industry, since it provides a shoe with removable heel.

BACKGROUND DK THE INVENTION

The heel is a rigid element that is part of the footwear, is attached to the back of the sole using various manufacturing techniques. Its main function is to act as a heel support, although for many people its aesthetics can also be considered as the most characteristic function: an example of this is to give the wearer greater height, reduce the dimensions of the foot with the naked eye, lengthen the legs and even show social or economic status.

The heel varies in its shape and size according to the various types of footwear in which it is used, so it can measure from a few millimeters to several centimeters in height or the area of contact with the surface.

Its classification is according to the use and region of the footwear; heel properties refer to its design, the materials with which it is manufactured, the different manufacturing techniques and its dimensions.

The beginnings of the heel date back to the Egyptians, when the handling of the cavalry was easier to using a little platform on the feet was the first approach to cowboy boots.

 In some of Leonardo Da Vinci's sketches, we can see men with high heels performing cavalry activities, we can realize that at this time the heel was a functional element, away from the aesthetic sense of our time.

It was at the wedding of Henry II of France and Catalina de Médici, in which a lady used this garment is documented for the first time, it was the perfect showcase for a new fashion, where all the girls wanted to acquire this new and modern accessory. Not only women at this time used heels, men also loved this trend, so the shoemaker's job was booming right now, one of the most renowned was Nicolás Lestage, who designed several models for King Louis XIV , even Madame de Pompadour, I get to use many of her designs.

This fashion spread rapidly in European courts and evolved until, in the twentieth century, certain heels exceeded 10 centimeters which forced those who used them to perform real juggling to avoid losing their balance. Currently a "normal" heel reaches 15 centimeters.

In 1760 an Italian merchant and designer, called Giacomo Pirandelli baron of Styletto, invented the stiletto heel, with the purpose of improving the performance of the riders and as a support for the spurs, the invention was a success and evolved to become a Essential element in women's clothing. Today, those who wear high heels are almost exclusively women, except in the case of men's boots (which also has its female counterpart). The heeled shoe is a common element of the dress of all social classes in many countries and cultures of the world, being used equally in everyday clothing as in the gala; There are a variety of styles, sizes, designs, colors and prices. The stiletto heel is one that has the quality of finishing at a point with a considerable length and is mainly used for events and social gatherings. Some women pay high sums of money for brand designs of shoes that wear this type of heel. In events of global interest, it is common to observe celebrities wearing this type of footwear.

The boot with heel is a garment made of leather or imitations of it, it is frequently used in equine and livestock activities.

Another type of boot is "The Cowboy Boot" which has as its main feature the thick heel, sometimes made of wood, or synthetic imitations of it and is characterized by an internal inclination. One of the most characteristic components is the "pointed", or "semi-pointed" tip, which may or may not have a bushing. The cowboy boot is used by both men and women.

Thick heeled shoes have positioned themselves in the last decade as an element of everyday women's clothing, mainly because it guarantees greater stability than the stiletto heel, without losing the rest properties of this type of shoe. There are a variety of shapes and styles in this type of heel.

The short heel is also frequently used by women; Many girls and teenagers begin using this type of heel first in order to gain experience in its use.

The use of technology in various areas of the industry has allowed revolutionizing the products offered, allowing to solve common problems, such as versatility and cost reduction; and the footwear industry is no exception, technology has been implemented in footwear, particularly women's, in order to have interchangeable heels, and the same shoe

A technical search was carried out regarding footwear with interchangeable heel and it was found that Tanya Heath Paris® is currently the brand through which a Canadian designer markets what she claims to be "the world's first multi-height shoes with removable heel". Just press a button inside the sole and slide the heel out to exchange it for another. The same in the opposite direction: with moving the heel inwards and listening to the internal click they will be fixed. However, it can be seen that the sole bridge that is formed is rigid and cannot be used without a high heel since its shape is not modified and if you want to use it at floor level, its configuration does not allow it. Another drawback with this shoe, is that to release the heel, the footwear must be removed from the foot, in order to be able to press the button that releases the heel, which makes the heel change uncomfortable and not so efficient. In 2008, the Mossto ® brand was born, developing an exclusive technology of interchangeable heels that allows you to vary the heel height quickly and easily without altering the aesthetics of the product. The design of the pieces and the use of new generation magnets allow a quick change in heel height, achieving a secure connection at the same time. They studied the morphology of the foot and the plantar pressures at different heights to develop a last designed to maintain comfort in different positions. However, the technology does not allow footwear to be used without a heel, if desired, it only helps to have a great diversity of heel shapes and sizes, but allows the removal of said heel.

The international publication of a patent application, number WO2007045699, published on April 26, 2007 with the title "REMOVABLE FOOTWEAR", describes a shoe comprising two independent pieces, but fixed together by means of snap fasteners, capable of being combined with other fasteners such as "sailboat" strips. The piece is integrated by the corresponding sole and the cut of the footwear, while the piece is made up of the heel in combination with a template with built-in cambrillón, being the fastening elements for the fixation between both pieces provided in the sole and in the insole , preferably in correspondence with the area of the enclosure of such elements. This document still, when mentioning that they are two independent pieces, the footwear cannot be used if they are separated, which makes it difficult to use, and due to the complexity of the sole, it is not possible to store several accessories in a simple way, to be able to combine them to the user's taste Another document is the United States patent number US8141275 (Bl), published on March 27, 2012 with the title "HEEL WITH PROTECTIVE COVER FOR SHOES", and describes a heel of a shoe that is protected by a protective cover that It has a conical sleeve with a wide upper end, a narrow lower end, and a wide upper end opening for the insertion of a heel of a shoe. The protective cover includes a fixing tab extending upwardly from the upper end of the sleeve and fixing tabs extending upwardly from the upper end of the sleeve. The heel of a shoe is inserted into the wide upper end of the sleeve, with the fixing tongue and the fixing eyelashes folded on the side and into the shoe so that a foot inserted in the shoe retains the fixing tabs and the fixing tabs coupled by a friction between the foot and the inside of the shoe. Like the inventions described above, it does not allow footwear to be used without a heel if desired.

One is the United States of America patent number US9326565 (Bl), published on May 3, 2016 with the title "HEEL WITH PROTECTIVE SHOE FOR SHOES", said patent describes a shoe with interchangeable attachable heel that includes an arranged connection post on a sole of a shoe, said connecting bridge is disposed between a stem and a counter of said footwear, in which an upper plate, arranged on top of at least one attachable heel, is connectable to the connecting bridge by means of a coupling , then, whereby a rhombus-shaped projection arranged above the upper plate is positioned to engage the interior to a connection opening arranged in the center over the bridge of sliding connection, and each of a pair of arcuate rails, slidably engages within each of a pair of arc-shaped channels arranged in the connection bridge, whereby a plurality of pins are extensible to the interior to each of a plurality of holes arranged in the connection bridge and the attachable heel, is conveniently insurable for custom wear on the connection seat, as desired.

Finally, U.S. Patent No. US9332806, published on May 10, 2016, describes a shoe that includes a sole that has a cavity, a first heel set and a second heel set that can be transferred from a position storage in the cavity to an unfolded position. In the deployed position, the second heel is below a heel part of the sole so that the contact surface of the second heel assembly is positioned in contact with the ground in case of wear, so that the shoe has a greater surface area of contact with the second heel assembly in the deployed position. Like the inventions described above, it does not allow footwear to be used without a heel if desired.
