EASY AND QUICK FOOTWEAR INSERTION AND SUBJECTION FOR SPORTS PRACTICE AND DAILY USE

Technical sector

The present invention is part of the footwear sector, especially in the 5 for sports practice as well as in the manufacture of conventional footwear.

Background of the invention

In the field of footwear different innovations are known aimed at facilitating the insertion of footwear in a simple and comfortable way without the need to bend down and not even in some of them the contribution of the hands is necessary for its placement, these ideas allow the use of these garments in elderly people with greater comfort or even constitute the only way to place them without needing help from another person, similarly they are very useful for other people who have some type of limitation in their mobility. In this way, as described, the state of the art includes inventions that include different mechanisms aimed at maximizing the area of footwear through which the foot or mouthpiece is introduced, constraining it after collation, these solutions are of complex manufacture and use; A sample of this typology can be seen in the patent document with publication number 20 ES2258936 of the applicant Francis Raluy who has the means to move the

Shoe instep or W02009 / 014433 requested by Tech-Nische Universiteit Delfit et al. which, by means of a hinge, divides the footwear into two movable parts, allowing the foot to fit comfortably in its opening position, closing this hinge by means of a locking system to hold the foot. Another 25 types of solutions mainly affect the area that constitutes the heel of the footwear so that when the foot is introduced through the mouth of the footwear it does not yield, this reinforcement acting as a shoehorn, this solution is usually achieved by cooperation of the mouthpiece that has a sufficient rigidity to maintain its shape in the introduction of the 30 foot analogously to the tongue in the case of laced footwear, in fact the applicant himself of the present application collects a solution that allows a comfortable way and simple the placement of footwear without the need to bend down or use your hands, with publication number U1180058 entitled shoe

Easy and quick insertion, although it presents technical solutions that improve the state of the art such as a removable tongue or the realization of an elastic instep whose stiffness allows the insertion of the foot and in turn acts as a tongue.

The technical problem apparently solved by the typologies of the reinforced heel type described stiffen this area in excess, being able to cause in the first instance discomfort in its normal use that is, when it is simply provided with a footwear with these stiffening reinforcements. This stiffening can generate, in sports practice or in daily use on a walk, an injurious impact on the portion of the Achilles heel near the calcaneus, with the execution of the plantar flexion of the foot (contrary to the dorsal) as well as dismiss its use if the lesion is already present.

Therefore, the applicant does not know of solutions such as that recommended in the present invention that offer compatibility between an easily inserted shoe that is biomechanically compatible with sports practice in a safe way.

Object of the invention

Provide the footwear industry in general, although especially the one dedicated to the preparation of sports footwear with means to achieve the easy and rapid insertion of the foot in the footwear without the need to bend down or use the hands for its placement or support, making compatible the necessary stiffness with biomechanical criteria, especially designed for sports practice where the explosive charges existing in athletic practice subject the calcaneus / Achilles tendon joint to strong solicitations, as well as in those footwear intended for continuous pressure work as in You spend long full days either static or walking.

Description of the invention

It is known the difficulty that some people have for different reasons to put on and fasten their shoes, it is also of interest in sports to have a simple technical solution that allows this progress, but

that is careful with the biomechanical requirements associated with this area of the foot and the strong solicitations to which it is subjected, especially in continuous work and in sports practice as previously stated. The proposed invention has means to stiffen the heel area, these means consist of incorporating a body of semi-rigid nature located in the described area that will allow to guarantee the dimensional integrity of the footwear, especially in footwear that by its nature has a heel pad too flexible; This stiffener body starts from the inside floor of the footwear, not exceeding the area occupied by the calcaneus bone, from this height a second stiffening body emerges characterized by having its subsequent displacement allowed, pivoting in the contact area with the preceding one, this allows Maximize the mouth of the footwear, preventing this rear area from being closed by the movement of the foot in the footwear, in addition to providing a support surface with a “slide” effect for the base of the heel of the foot in the footwear process. This second body is characterized by freeing the contact area with the start of the Achilles tendon considered from the heel, thereby avoiding fatigue due to the repetitive impacts that occur on the rigid heels of other quick-insert shoes, so that the geometry with which it is conceived will always run on the sides of the tendon, as it can be by way of example an element next to a "U". Both bodies will be made preferably in plastic materials defining their degree of stiffness / elasticity by means known as the change of materials, presence of nerves, notches or by the selective change of their thicknesses. Versions are designed to ensure that the area of the mouth of the footwear retains its shape in the insertion of the foot, providing this area with a body that surrounds the aforementioned designed opening with a combination of its stiffness / elasticity that allows it to slightly retract insert the foot but it can regain its strength when this external pressure ceases while maintaining its initial form. Versions are provided in which this described body can be easily inserted during the manufacture of footwear by inserting it between the outer layer of finish and the inner lining, this semi-rigid body will preferably be made of plastic, elastic and consistent material, the perimeter area being close to the mouthpiece provided with a rounding radius that contributes to the foot entering the footwear more comfortably and easily, orienting the foot towards the mouthpiece or insertion zone by a funnel effect;

in the case that the shoe has laces and / or tongue, the body inserted in the mouth will have a through opening (not shown) located under the area covered by the laces in such a way that the tensioning and tying of the laces is allowed, this Tying operation is performed the first time we put on the footwear, or if the user wants to readjust the tension of the laces, not being necessary for the placement or relocation of the footwear.

Versions are planned in which the part of the hunt that wraps the instep of the foot consists of a flexible material in order to facilitate the insertion of the footwear and its retention.

5 Description of a preferred embodiment

A preferred embodiment is cited by way of example, being independent of the object of the invention the materials used in its manufacture, as well as the methods of application and all the accessory details that may arise, as long as they do not affect its essentiality.

10 The footwear of this preferred embodiment has means to facilitate its insertion without the need to bend down or use your hands during this operation, these means are provided by a stiffening element (2) located in the heel area that, starting from the sole, rises to cover the calcaneus bone, giving additional consistency to footwear whose heel (3) due to its construction may not have sufficient stiffness and deform when the foot is introduced. From this described stiffening element, a second stiffening body part (1), which allows a relative rotation with respect to the first in the direction outside the mouth as shown in Figure 2, allows to improve the insertion of the foot while preventing this area from invading the mouth. This second stiffening body has the characteristic of not invading the contact area of the Achilles tendon, which is of the utmost importance to prevent possible injuries due to impact and repetitive friction, in this way it is characterized by reinforcing both sides of it, in this embodiment It preferably takes a form close to a "U" (1) Figure 3. The degree of stiffness / elasticity of both bodies is achieved by means known as the choice of materials or the compromise between their thicknesses, reinforcements or notches. Cooperating with the elements described, the recommended footwear comprises an element (4) to ensure that the mouth area will maintain its shape when we insert the foot through it, it covers at least the perimeter of the mouth so that it has the sufficient rigidity to maintain its shape as described but in turn allow the mouth to recover the small deformations that it may have suffered after entering the foot. The perimeter area of the mouth has a rounding (5) to the outside of it that facilitates the
