SHOE HEEL WITH POLYURETHANE DERIVATIVE AND PRODUCTION
METHOD THEREOF
Technical Field
The invention relates to the heel used in men's and women's shoes.
The invention relates in particular to shoe heel with polyurethane derivative used in men's and women's shoes which is light, easy to produce and has a flexible structure and production method thereof.
Background of the Invention
Today, the shoe sector is advancing rapidly and various models are offered on the market with aesthetics and elegance given a particular importance. It is of great importance that said shoes, in addition to being aesthetically appealing and elegant, do not adversely affect foot health and shoes that are comfortable to use are developed.
One of the crucial parts of shoes that affect foot health is the heelpiece, known as the shoe's heel part.
With the heel being the part which carries the load of the body, it is important in terms of foot health that this part is comfortable.
Because the heels, used in the present state of the art, do not produce flexion in a desired manner during walking, they cause pain in our feet and heels at the end of the day. Heels, which cannot provide full flexion by the nature of the materials used, also, being rigid, apply a pressure to the heel zone during walking.
Again, because of the nature of the material used, said heel is heavy and this increases the total weight of the shoes and causes fatigue in the feet of the user.
Difficulties are experienced from time to time in the production of said heels. In terms of the process, it is a long and laborious work.
In today's technology, materials such as IMITATION LEATHER, MDF, HDF, which are arduous to prepare are being used for the production of heels. Processes such as carving out the insides of the heels produced with said materials, affixing the layers one by one, as well as bringing along additional workmanship, extend production time and complicate the production.
The difficulty of bonding the leather which is placed in front of the said heel also causes problems experienced in the production.
In the present state of the art, in a helpful model application, number TR 2005 00060, regarding the subject, the expressions "The presence of a leverage system which applies the sole profile most accommodating for human and foot health, made to conform to the sole profile of our feet and with the geometric system of the shoe sole, used for pressing on the ground and lifting off the heel, with a leverage support to press on the ground and the road, with a breadthwise leverage support at the joining point of the foot sole border and the foot talus foot sole border, the functioning of the leverage and lifting the heel off also when the body weight is added and facilitating a forward motion of the leg simultaneously with the step with the body in comfort and, with the repeating of our steps in both of the feet, ensuring that effort is dispensed in the shoe which we have developed" are mentioned.
In the application mentioned, a mechanical shoe providing ease of walking is referred to.
Again in the present state of the art, in a helpful model application, number TR 2004 02324, regarding the subject, the expressions "The invention relates to a heelpiece (heel) machine, used in the production of heels that are used in feet protective and rest wear such as shoes, high boots, boots and slippers, comprising at least one heel, at least one heel compression jaw which shapes the said heel and which embodies it at least one heel pad and which comprises arms with mobile upper and lower sections that are placed near the said pad in order to form the ovalness of the external and the internal sides." are mentioned.
Also in the application referred to a machine us for heel production is mentioned.
Due to the disadvantages mentioned above, a quest was embarked on, for an innovation in the production of shoe heels.
Disclosure of the Invention
Based on this state of the art, the object of the invention is to construct a heel which eliminates the disadvantages mentioned.
Another object of the invention is to construct a lightweight structure that provides ease for the user.
Another object of the invention is the construct a structure which is easy to manufacture due to the fact that it does not involve processes such as the carving out of the insides of said heels and binding the layers one by one.
Another object of the invention is to construct a structure having a shorter production time.
Another object of the invention is to construct a structure which enables the flexion of the heel zone of the feet in the desired form during walking.
Another object of the invention is the construct a structure which prevents foot health problems which may arise subsequent to walking, by providing ease of walking for the user.

Detailed Description of the Invention
The invention relates to a shoe heel with polyurethane derivative (2) used in men's and women's shoes, which is lightweight, easy to manufacture and has a flexible structure, and to the production method thereof.
In Figure -1 the side view of the polyurethane derivative shoe heel (2), the subject matter of the invention, is shown.
The invention .comprises the shoe heel with polyurethane derivative (2) and the coating layer (1 ) positioned around the said shoe heel with polyurethane derivative (2).
For the production of the invention, metal forms in the shape of the heel are used. Firstly the coating layer (1 ) prepared in various millimeters and layers are wrapped onto the inner side surfaces of the said metal form. As for the inner surface, adhesive is applied on the inner face of the said coating layer (1 ).
Later, a polyurethane or derivative material is injected into the said metal form. The said polyurethane material assumes the heel shape of the form inside the said form and takes shape as the shoe heel with polyurethane derivative (2). The said shoe heel with polyurethane derivative (2) is bonded to the coating layer (1 ) wrapped around it via the adhesive on the internal surface of said coating layer (1 ).
Thus, the said shoe heel with polyurethane derivative (2) is removed from the form, with the coating layer (1 ) wrapped around it.
In a preferred embodiment of the invention the said coating layer (1 ) is made from leather or imitation leather.
In a preferred embodiment of the invention, the leather (3.1 ) is positioned on the front area of the said cover (3).
The external appearance of the shoe heel with polyurethane derivative (2) mentioned is that of an imitation leather or leather heel, since completely enveloped in the coating layer (1 ).
Because that section of the mentioned polyurethane derivative shoe heel (2) which is in contact with the ground assumes the shape of the form it is used as
the cover (heel base) (3). Thus, the cover (3) section is also removed from the form in one piece, without any need for an additional layer.
In the preferred embodiments of the invention the mentioned polyurethane derivative shoe heel (2) is made from a TPU, poly, PVC type material.
The scope of protection of this application is specified in the Claims section and may not be limited to those described in the foregoing absolutely for representative purposes. It is evident that a person specialized in the technology can construct the innovation introduced with the invention by using similar constructions and/or can apply this construct in other fields used in the technology serving a similar purpose. Therefore, it is also evident that such constructs shall be devoid of the criteria of innovation, and particularly of surpassing the present state of the art.
