DESCRIPTION INTRODUCED IN SEMI-RIGID MIDDLE REAR MIDDLE REGULATION, preferably applies to shoes (S), the highlight of which is the posterior middle portion made of semi-rigid thermoplastic material (1) injected into the arcuate shape with inferior concavity (2) and superior convexity (3), which gives a spring effect when walking.

Description

"PROVISION INTRODUCED IN PALM WITH SEMI-RIGID REAR MIDDLE REGION"

It addresses the present Utility Model Patent application for an unpublished "SEMI-RIGID MIDDLE REAR MIDDLE ARRANGEMENT" especially an insole with the common front, but with the anterior middle portion formed by semi-rigid thermoplastic material and anatomical, where comfort is given precisely by the spring effect, resulting from the resilience of such material when subjected to the particular efforts of walking.

The insole is commonly used in the footwear sector especially in shoes and, considering the high degree of competitiveness of this sector, is that manufacturers seek frequent innovations that combine aesthetics and functional aspects focused on comfort and health.

The feet of the human being are highly demanded since it is the point of contact / support with the ground in walking, being normal the appearance of injuries and pain in everyday life.

This is due to the loosening or ligament shortening of the plantar fascia, which alters physiological curvature resulting in impaired foot functionality.

Some footwear by nature of design or frequent use cannot provide an ideal pattern of plantar pressure distribution, and the solution to this problem is the use of insoles.

In a particular study on the distribution of strength in the foot, it was observed that the hindfoot region had the highest load, as well as the forefoot. According to the three regions of the foot which are: hindfoot (which determines the pressure exerted on the calcaneus); forefoot (determines the pressure on the heads of the metatarsals and toes, and the midfoot representing the pressure normally exerted on the external longitudinal arch of the foot, approximately 60% of the weight is distributed on the heel, 34% on the forefoot and 6% on the midfoot.

As a result, the manufacturer who is most attentive to the technical and

Anthropometric measurements of the feet should adequately compensate their products for different load requirements, including in accordance with the focus of this privilege request, by improving and improving the insoles using new technologies and features. The current state of the art anticipates some patent documents which

on the subject under consideration, such as MU8802400-8, entitled "VENTILATION DRAIN APPLIED APPLICATION", requests the privilege of a vented insole whose heel region is formed by a massive semi-long projection just to enter the cavity. compatible on the sole. In this case, the insole aims to promote circulation

air inside the shoe.

Also part of the state of the art is Pl 0400961 -4 "Constructive Arrangement Introduced in Footwear Assembly Process with Impact Absorbing Device and Resulting Product". Composed of a footwear sole element, composed of a recess in the front portion and another recessed element in the rear portion to which the damping element fits, thus obtaining a sole and damper assembly which, once joined to the assembled leather element, obtains the final leather assembly. and sole, which is complemented by the placement of an insole and heel element inside. The combination of materials proposed above creates a recess to be filled with more flexible material, which over time generates a natural wear of the softer part that gradually becomes an inconvenience, as the user's foot becomes in direct contact. with the peripheral part or, more rigid. That is, the softer part that was previously slightly higher than the rest is ineffective and lower.

Aware of the state of the art, its shortcomings and limitations, the inventor, after study and research, created the "SEMI-RIGID MIDDLE POSITION ARRANGEMENT" in question, which is generally an insole where comfort is not It is associated with the softness of the material used but rather with the use of semi-rigid material in the middle and anterior portion, which added to the concave shape gives a spring effect resulting in a softer gait and a feeling of lightness. This portion is obtained in thermoplastic injected in the arcuate shape convex in the region in contact with the footwear and convex in the opposite face where there are some foam grafts below the leather finish. Finally, at the front the insole features a foam blade attached to the rigid back and top leather trim.

In short, the claimed innovation has the most important advantages:

> The semi-rigid material produces a spring effect providing a smooth and light gait;

> Higher strength, prevents deformation with use;

> Stabilizes the foot;

> Ensures greater safety when walking;

> Comfortable, even for those with flat feet. The following explains the model with reference to the accompanying drawings, in which they are shown by way of illustration and not limitation:

The "Arrangement Introduced in Semi-Rigid Posterior MIDDLE WEEK", which is the subject of this Utility Model Patent Application, applies preferably to shoes (S), the highlight of which is the posterior middle portion made of semi-rigid thermoplastic material ( 1) Injected into the arched shape with lower concavity (2) and upper convexity (3), which gives a spring effect when walking.

The innovative insole (P) has its front part (A) made of foam (4) covered by leather trim (5). The highlight of the insole (P) is the fact that it has the posterior middle portion (MP). that is, the contiguous front part (A) explained above is made of semi-rigid injected thermoplastic material (1), with an arcuate contour delineating a concavity (2) on the underside supporting the shoe (S) and, convexity ( 3) superior in contact with the foot following its ergonomics. Thus, the combination of the semi-rigid material (1) and the shape gives a spring effect during walking, which is performed with great comfort. Between the semi-rigid material (1) and the leather finish (5) are strategically positioned foam grafts (6), further enhancing the feeling of lightness and comfort. Finally, the insole may have a fastening system made of shoes by means of velcro (7).

Therefore, the present utility model application is new and inventive thanks to the spring effect achieved by differentiating itself from the other insoles whose comfort is directly related to the softness of the material with which it is manufactured, which added to the industrial application deserves the privilege.
