Description

"IMPROVEMENTS INTRODUCED IN FOOTBALL FOOTBALL SOLES AND FOOTWEARS DONATED BY EXPANSIBLE MEDIA".

TECHNICAL FIELD

The present invention relates to footwear and sole improvements of footwear generally having expandable means, which have been notably developed for immediate adaptation to various foot sizes and shapes by numerically altering footwear; said alteration or expansion is accomplished through the integration of interconnecting means and extenders that allow the perfect comfort of the user; For this purpose, the improved footwear is transversely split, forming two complementary parts, namely: leather front set and coupling sole and rear leather set and adjustment sole; the rear adjusting assembly comprises extension means configured by at least one tongue-shaped spacer provided with engaging and locking elements and with respect to a regulating cavity provided in the front leather coupling assembly; In order for the footwear to be mounted and adjusted to the user's foot, adjustment means configured by elastics, velcro or others are provided between the front and rear assemblies, besides having a protective insole.

TECHNICAL BACKGROUNDS

As is well known, ideal footwear should have essential fabric shape and quality characteristics, such as adequate toe size in the toe box, softness in the inner sole of the foot, concordance of the foot curvature of the foot. sole with the curvature of the sole and especially the size of the footwear should be proportional to the size of the foot, ie without too much play or too tight.

The daily use of improper and uncomfortable shoes, ie narrow, tight or very large shoes can lead to numerous complications, such as injuries, permanent deformities, ingrown toenails, blisters, chilblains, especially for users who remain in position for a long time. orthostatic.

However, there are a number of unexpected factors that make it impossible to wear suitable footwear that, at the time of purchase, often presents comfort, such as: abnormal accumulation of muscle tissue, long trips by plane or bus, menstrual periods, skin burns. sun, generalized allergy, venous insufficiency, malnutrition, contraceptive intake, among others.

Another factor that promotes the rapid and frequent disabling of a shoe is the acquisition of it during the growth phase of children, where it is verified that through the constant growth of the feet the prolonged use of a shoe is impossible or it can make that the child uses the shoes incorrectly, that is, tight or narrow hindering the proper development of the feet.

Currently, there are some models of children's shoes, female and / or men in the market that have the closure of the leather by means of velcro allowing the volumetric widening of the footwear and, consequently, a limited extension of its useful life. However, this closing means does not change the length of the sole and leather making it impossible to use the same shoes during child growth.

In searches conducted in database was found a document no. MU 8402467-4 deals with the adjustment device that allows the increase of the useful life of a children's footwear as its application allows a change in the size of the footwear. Such adjustment device consists of the mounting of toothed gear and insole next to the cursor component, and the practical effect obtained is based on an action of changing the size of the footwear. The first intervention to change the length is performed by inserting a screwdriver-like tool through the slot provided in the toothed gear component, generating the vertical displacement of the so-called horizontal beam portion of this component. The result is the release of the teeth along the aligned hollow elements of the cursor component, allowing the displacement force of the assembled component to be applied, resulting in a longer final configuration where locking of this new configuration is achieved when the new alignment is made. between teeth elements of the toothed ratchet component and aligned hollow elements of the cursor component; The coil spring brings the base of the tool to the original position, raising the teeth again, providing a new fit between the parts.

The main drawback of this document is the fact that it presents great complexity of the elements that develop the longitudinal displacement between the parts that make up the footwear promoting an increase in the value of the product, in addition to making the concert impossible in a possible break. BRIEF DESCRIPTION OF OBJECT

With the intention of providing improvements to the consumer market, the applicant has developed improvements made to sole and leather of footwear generally with expandable media, notably designed for immediate adaptation to various foot sizes and shapes by numerical alteration through the integration of media. interconnectors and extender media. applied between the front set of leather and sole and the rear set of leather and sole, allowing greater user comfort, as it eliminates frequent replacement of shoes due to discomfort or growth of the feet of children and young people.

To this end, the improved footwear is transversely split, forming, as stated above, two complementary parts, namely: a front set of leather and coupling sole and a rear set of leather and adjustment sole, the set of which The rear adjustment includes an extender configured by a tongue provided with locking means when engaging a corresponding adjustment cavity provided in the front assembly of leather and coupling sole.

In order to keep the footwear always mounted and adjusted to the user's foot, automatic or manual interconnecting means are provided that adjust between the sets, which can be configured by elastic, velcro or other means and which are applied to the side walls. front and rear assemblies.

In this way, the user, by means of longitudinal decoupling of the front coupling assemblies and after adjustment of the improved footwear, chooses the best grading for the footwear through the grading means provided in the set formed by the tongue and its cavity, as well as the lateral adjustment means, formed by the elastic and others, and after adjustment of the shoe the user introduces the respective protective insole.

It is, therefore, the object of the present invention to provide that the footwear is provided with interconnecting and extending means that allow, quickly and practically, the anatomical adjustment of the footwear on the user's foot, enabling the adaptation of said footwear to the dimensional variations that may occur. it may be the accompaniment of numerical variations of infant feet or in relation to physical impairments such as swelling and others.

Another objective achieved with the present improvement in footwear is the fact that the bipartition of the footwear allows the assembly of various models, simply by having the front part of one shoe receive the rear part of another shoe with identical footwear. fitting and mounting characteristics, which can alternate colors and shapes.

Another advantage lies in the fact that the horizontal extension of the footwear promotes economy, especially in children's numbers where growth is accelerated.

DETAILED OBJECT DESCRIPTION

With reference to the drawings, the present invention relates to "PERFORMANCE INTRODUCED IN SOLES AND FOOTWEAR GENERATED FOOTWEAR", more specifically footwear (1) with extension (ME) and interconnecting (MI) media. applicable to leather (C) and sole (S) assemblies, notably designed for immediate adaptation to various foot sizes and shapes through numerical change, allowing for greater user comfort, reducing the time for such frequent replacement. footwear (1), whether as a result of numerical variation (infant feet) or for physical adaptations (swelling and other disorders).

According to the present invention, the footwear (1) is transversely split forming two complementary parts, namely: a leather front and coupling sole assembly (2) and a rear assembly of adjustment sole (3), to which the extension means (ME) and interconnecting means (MI) are applied for horizontal extension (PH), said extension means being configured by a coupling spacer (4) in the central tongue (4a) which, in turn, has engaging and clamping means (MF) for adaptation and mounting in the regulating cavity (5) disposed in the leather assembly and coupling sole (2).

Said central tab (4a) extends from the front face (3b) of the sole (3a) of the regulating assembly (3) formed by a plate (4b) whose clamping and engaging means (MF) are, in a constructive option, configured by multiple graduating shoulders (4c) which remain arranged transversely, orderly and parallel to each other, preferably arranged on the upper face (4d) of said central tab (4a) thus forming multiple areas in individual recesses (4e) in which Velcro strips (VI) or the like are applied, while the entire lower face (4d ') of said central tab (4a) receives the complementary strap of the velcro portion (V2).

Said regulating cavity (5) of the coupling assembly (2) has a peripheral shape identical to the peripheral shape of the plate (4b), and the coplanar face (5a) of the central tongue (4a) of the regulating cavity (5) is provided with multiple recesses (5b) corresponding to the graduating shoulders (4c) of said central tab (4a) also configuring areas in individual recesses (5c) where velcro portions (VI ') corresponding to the velcro portions (VI) of the central tab are applied. (4a).

The coplanar face (5d) the velcro portion (V2) of the central tongue (4a) has the complementary velcro portion (V2 ') by configuring the locking and locking means (MF) of the central tab (4a) in the regulating cavity (5).

Said interconnecting means (MI), in a constructive option, is configured by side flaps (6) disposed on each leather portion (C) of both coupling front (2) and rear adjustment (3) assemblies, whose inner faces (6a ) and outer (6a ') of each flap (6) comprise corresponding velcro portions (V3) for attachment and anatomical adjustment to the user's feet when horizontally extending the footwear.

Thus, the distance (x) between each grading shoulder (4c) and the distance (y) between each corresponding recess (5b) determines the horizontal extension (PH) and gradation desired by the user by longitudinally decoupling the coupling assemblies ( 2) and adjustment (3) of footwear (1).

Said footwear (1) also accompanies a set of protective insoles (PP) of various sizes for introduction after mounting the footwear (1).

Admittedly, when the present invention is put into practice, modifications may be made with respect to certain details of construction and shape, without implying departing from the fundamental principles which are clearly substantiated in the claim framework, thereby extending that the terminology employed was for the purpose and not for limitation.
