Description

NON-SLIP INVISIBLE SOCK STRUCTURE

Technical Field of the Invention: The present invention relates to a novel invisible sock structure that cannot be seen from outside of shoe, that does not slip from foot ' s surface through the natural rubber structure it comprises and that wraps firmly around the foot.

State of the Art :

There are various types of sock utilized within the state of the art. One of these types is invisible sock structures namely no- show socks sized in such a way that it cannot be seen from the outside of the shoe structure. The subject matter invisible sock structures are predominantly used for aesthetic purposes by their users who wants to wear socks but do not want their socks to be seen from outside. Therefore, users prefer invisible socks in cases where they do not want socks they wear to be seen from outside. Sizes of invisible socks are selected in such a way that they will not exceed the sizes of shoes and thereby designed in a manner that wraps around the foot structure entirely. In addition to their use for aesthetic purposes, they are frequently preferred for daily use because of their structural simplicity and since provide ease of use.

It is observed that users of invisible socks experience various problems in the state of the art based on the extensive use of invisible sock structures. Slipping of invisible sock structures from foot or shoe surfaces over time is the leading issue among these problems. A condition such as this may result in various injuries by inducing loss of balance during movement for people who are wearing invisible socks. Even if an injury is not within occasion, there are circumstances in which users' feeling of discomfort during use can be observed. Furthermore, based on the slipping of invisible socks during the use towards aesthetic purposes, situations involving the appearing of sock structure from outside of the shoe may occur. A situation such as this gives rise to the emergence of an aesthetic problem that users do not want to experience.

The fundamental solution utilized within the state of the art in order to prevent invisible sock structures from slipping foot surface or shoe's interior, is the procedure towards the positioning of materials such as silicone, etc. in the shape of a fine strip to the cuff portion of the sock fitting to Achilles tendon part in the heel region's upper section of the invisible sock structure. By means of this process, a silicone-like structure increases friction between the foot structure and invisible sock by gripping on foot surface from Achilles tendon region, thus reducing slipping intensity.

Even though the coating process of sock's cuff portion which comes into contact with Achilles tendon with a material such as silicone, etc. utilized in the state of the art reduces the intensity of slipping, desired performance cannot be achieved. The main reason behind this is that the friction coefficients of silicone, etc. structures remain insufficient in terms of efficacy in applied quantities. Since the applied area is solely the side surface of sock's cuff portion with only Achilles tendon section, adequate friction force cannot be generated.

The subject matter silicone, etc. material application method also constitutes different disadvantages. One of these problems is the obligation of carrying out an additional process performed in order to attach silicone, etc. structure to invisible sock structure. In attaching of silicone, etc. structure to the invisible sock structure, and additional process such as sewing or pressing is carried out during production process. This results in lengthening of manufacturing process. Furthermore, manufacturing cost increases depending on the processing and usage of silicone, etc. materials. In addition to inefficiency of silicone, etc. materials attached to invisible sock structures in terms of providing adequate friction force, in cases where these materials are exposed to water or get wet due to perspiration friction capabilities drop even further. Therefore, circumstances such as these, cause slipping problems to be on the increase in the state of the art and prevent the usage of materials like silicone, etc. in invisible sock structures from being an adequate solution against problems of slipping.

Another problem encountered regarding invisible sock structures commonly used in the state of the art is the necessity towards additional processes during production for properly finishing of cuff portions. In cases where abovement ioned cuff finishing stitches are not made, it is observed that cuff portions of invisible sock structures are unraveled in a short span of time. Hence, an additional cuff finishing sewing process that lengthens the manufacturing process becomes necessary in order to obtain a proper invisible sock structure.

Disclosure of the Invention:

The present invention relates to a novel invisible sock structure (1) that cannot be seen from outside of the shoe during use and that does not slip from the surface of foot structure or from the inner surface of the shoe through the uncoated natural rubber threads it comprises.

The invisible sock structure (1), as it can be seen in both Figure 1 and Figure 2, comprises a novel cuff portion (2) produced by using a special weaving process. Aforesaid sock cuff (2) structure provides non-slip characteristic to the subject matter invention invisible sock (1) structure.

The inner part of the sock cuff (2) structure, as it can clearly be seen in Figure 3, is composed of natural rubber threads utilized in their pure state that does not contain any coating layer upon. Abovementioned uncoated natural rubber threads constitute inner section of the sock cuff (2) portion of the subject matter invention invisible sock (1) structure by means of being sewn in knitting form as a standard thread structure. The part remaining outside of the sock cuff (2) portion of the subject matter invention invisible sock (1) structure is constituted by any type of standard thread structures that are being utilized in sock manufacturing. Both sock cuff (2) portion and other invisible sock (1) portions remaining outside of this portion can be constituted within the same sewing line. Uncoated natural rubber threads that constitute the structure of the sock cuff (2) possess the same structure with other threads that can be used within the same sewing and weaving lines.

Because uncoated natural rubber threads are obtained through purely natural means and are not subjected to any type of coating processes, they are not only an affordable raw material but also have high friction coefficients based on the characteristic features of the rubber. By means of being sewn in knitting form in particular, extending of surface areas that come into contact with foot structure and the inner surface of shoes whereby the intensity of the friction force generated is increased. Thus, maximum level gripping of invisible sock (1) structures on to foot surfaces of users is achieved. The inner surface of the sock cuff (2) which is composed of uncoated natural rubber threads, ensures remaining stable on its location by firmly gripping on foot surfaces of users. Therefore, the subject matter invisible sock (1) structure does not slip from users' feet and does not constitute problems such as going out or running inside of the shoe.

Since uncoated rubber threads are utilized within the inner part of the sock cuff (2) portion of the subject matter invention invisible sock structure (1), problems such as abrasion of sock cuff (2) structure due to usage or unraveling over time are not encountered. Moreover, since uncoated natural rubber does not suffer from a loss in terms of its high friction coefficient characteristics in case of getting wet, depending on its physical characteristics, occurrence of potential slipping problems which users may encounter during use of the invisible sock (1) due to wetting are avoided.

Uncoated natural rubber threads within the structure of the subject matter invisible sock (1) are only used in the inner part of the sock cuff (2) portion. However, this condition may vary based on preference. Therefore, uncoated natural rubber threads can be utilized within different portions of invisible sock (1) structure in case it is preferred. For instance, usage amount of uncoated natural rubber threads can be reduced by means of constituting only the portion that comes into contact with Achilles tendon of sock cuff (2) structure out of uncoated natural rubber threads. Or friction force with a different intensity can be generated by constituting a portion located at the tip of the foot out of uncoated natural rubber threads.

Since any materials like silicone, etc. are not utilized in abovementioned invisible sock (1) structures, no additional combining processes are needed. This provides shortening of the manufacturing process. Because any additional materials such as silicone, etc. are not needed manufacturing costs are also reduced. Furthermore, executing of the production process with a single sewing procedure and the fact that no further processes are needed provide facilitation in manufacturing. Therefore, with the subject matter invention invisible sock (1) structure, a novel invisible sock (1) structure that is cost effective, that can be produced through a single manufacturing process and that has maximum level non-slip characteristics is provided.
