Abstract

Footwear with interchangeable cuts to different bases and adaptable to the width of the foot, characterized in that it comprises two pieces, a base and a completely separate cut, which allow interchangeability with each other by means of fixing pieces that can be rings, washers, clasps, hooks , buckles or loops in different materials, sewn or glued to the base according to traditional shoemaking methods and that allow assembly with the upper, which is the design and includes a closure system to the base and adjustment to the width of the foot with pieces such as buckles, brooches, hooks, rings, laces or ribbons.

Description

DESCRIPTION

Footwear with interchangeable cuts to different bases and adaptable to the width of the foot

Technical sector

This utility model application belongs to the field of shoe manufacturing and its purpose is to register a shoe manufacturing and design system that allows the upper (everything that is above the sole of the foot) to be exchanged with bases. of footwear (everything that remains under the soles of the foot such as soles, soles, insoles, heels, wedges, platforms, etc.) as well as the adaptation of the models to any foot width through an adjustable closure system incorporated into the design of the outside of the shoe.

Background of the invention

Traditional footwear is made by joining the upper to the base of the shoe by means of adhesives or sewing. There are different methods to assemble them such as glued, injected, vulcanized, kiowa, billy or halley (outside stitching), blake (inside stitching) or goodyear (double stitching), gluing being the most widely used in the industry where high performance glues are used. , resulting in an effective union that allows mass and fast production.

All these traditional shoe assembly or assembly systems do not allow the user to separate the upper from the base in order to combine uppers with different bases, resulting in new models.

In the market we find standard footwear based on anthropometric measurements of the foot that most of the time do not adjust to the real widths, the user having to buy one more size if his foot is wider, something that causes acquired deformations in the foot (bunions, claw toes...) and injuries (eg plantar fasciitis) due to the use of inappropriate footwear. All footwear should respect the length of the foot or length of the plantar surface, as well as the width corresponding to the perimeter of the metatarsophalangeal joints, otherwise excessive pressure will be exerted at the level of the metatarsophalangeal and interphalangeal joints that will cause friction, favoring the appearance of of calluses and that will make the fingers ride and the nails collide with the toe. However, at a commercial level it is not viable to have different widths for each size, so a large part of the population is wearing shoes that do not fit, affecting their health and quality of life.

There is no commercialized shoe model on the market that allows the user to create their own design by buying bases and cuts separately. This exchange would contribute to a more sustainable consumption for the fashion industry. For example, with a base and two uppers, two different models would be obtained and in the event of deterioration of one of the two parts, it could be easily replaced without having to buy a new shoe.

Explanation of the invention

For the development of this type of footwear with interchangeable designs, biomechanical and ergonomics factors have been taken into account in its design, from the conception and manufacture of the product, comfort, safety, efficiency, ease of use, durability and a pleasant appearance, in accordance with the aesthetic trends of the moment.

This shoe with interchangeable designs consists of two parts, the upper and the base.

We call base, everything that is below the sole of the foot and may be formed, depending on the model, by the insole, pads, assembled plant, soles of different materials used in the footwear industry such as leather, jute, rubber , PVC or TPU thermoplastic soles, polyurethane, Eva or crepe among many others, heels, platforms or wedges in all its versions.

The pieces that will be used to assemble the shoe with the upper will be fixed to the base by sewing or gluing. These pieces can be metallic, such as rings, washers, clasps, hooks, buckles, etc. or belt loops in materials such as leather or textiles, among others. The pieces will be assembled to the base using the usual manufacturing systems mentioned above, such as the glued, hand-sewn or machine-sewn system in all its variants (including billy or halley, blake or goodyear), injected or vulcanized, using in each case the necessary machinery, tools and materials.

The cut (everything that remains above the sole of the foot) will be the design and this may consist of one or several pieces, depending on the specific model to be developed. The upper must have buckles, snaps, hooks, rings, laces or ribbons as a closure system adjustable to the base and width of the foot. The upper of a certain design will be manufactured as the upper of a shoe is usually made in its different sections of pattern making, selection of materials, ornaments, cutting, dressing and pasting of the pieces.

The upper will be attached to the base through the aforementioned pieces for assembling the shoe and will adjust to the foot and to the different widths with the adjustable closure system also already described in the previous paragraph.

Consisting of two completely separate parts, cut and base, these can be interchanged with each other.

The base can be found in different shapes, heights, colors, etc. and cutting in different designs, colors, materials, etc. This allows versatility to make all possible combinations, adapting to the tastes and preferences of each user. Also, in the event of deterioration of any of the parts, it makes it possible to replace them separately without having to change the entire shoe, which will have a favorable environmental impact and will extend the useful life of the shoe.

Brief description of the drawings

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part of said description, where, with an illustrative and non-limiting nature, what has been represented has been following:

Figure 1.- Corresponds to a base.

Figure 2.- Corresponds to the fastening piece formed by a leather loop and an oval metallic ring.

Figure 3.- Shows how 4 clamping pieces have been fixed using the method of gluing to the base.

Figure 4.- Shows the cut of the model with a buckle.

Figure 5.- Corresponds to the assembly of the base with the cut of the model.

Preferred embodiment of the invention

This shoe with interchangeable cuts to different bases and adaptable to the width of the foot consists of a base (figure 1) to which four fastening pieces have been fixed (figure 2) by means of the traditional gluing system. These pieces have been placed in different positions (figure 3) according to a cut of a specific model (figure 4).

The upper (figure 4) has been made as traditionally done in the footwear industry, using a buckle (4a) from figure 4 as a closure and adjustment system, and at the opposite end different holes (4b) from figure 4.

Figure 5 shows the result of joining the base of figure 1 with the cut of figure 4. To do this, the end of the cut (4c) of figure 4 is first passed through the clamping piece (3c) of figure 3, leaving the buckle (4a) of figure 4 at the height of the outer face of the ankle. Next, the end of the cut (4c) of figure 4 continues to be passed through the holding piece (3b) of figure 3, crossing the instep of the foot. Continue passing the end (4c) of figure 4 over the fingers to the holding piece (3a) of figure 3. Again the cut crosses the instep introducing the end (4c) of figure 4 through the piece fastening (3d) of figure 3. Finally, after turning the ankle, the end (4c) of figure 4 is inserted through the buckle (4a) of figure 4 using the corresponding hole (4b) of the Figure 4 to achieve an adequate adjustment to the width of the foot.
