Description

Technical field

The technical solution relates to a specially made sock with the characteristics of footwear, which is easy to store and is used occasionally instead of classic shoes.

BACKGROUND OF THE INVENTION

For the purpose of foot protection and human walking, the most commonly used means is shoe. We know a wide range of shoes, which differ mainly in their appearance and properties according to their purpose and use. From women's high heels to sports shoes for hiking. All types of shoes have a similar construction, despite the differences in their shape. For the purpose of isolating and protecting the human foot from the ground and the weather, a sole can be added to the heel on which the upper part of the shoe is attached, either as an elastic slip-on part or with a mechanism (laces, buckles, Velcro). From the medical point of view, the biggest drawback of classic solid-soled footwear is that the human foot is physiologically adapted to walk barefoot, and especially orthopedically inadequate footwear can be harmful to health just by pointing to the shape and shape of the arch of the human foot.

Such a disadvantage is to some extent eliminated by footwear which has a weakened sole and movement in it should simulate walking barefoot. This trend is indicated mainly by the English term "barefoot". Barefoot shoes have a thin sole (from about 3 to 6 mm). In addition to barefoot shoes, you can distinguish the shoe with the so-called minimalist sole, which has a thickness of about 7 to 13 mm. The aim of the weak sole is to provide maximum sensory feedback to the brain (so-called proprioception) because 70% of the information the brain receives about movement comes from nerve endings that are located on the human feet. Technical solutions for shoes with minimal soles are based on the fact that the better and more direct the contact of the foot with the ground, the more natural is the movement and response of the human body to the environment in which it moves.

Barefoot shoes, as well as a classic shoe with a fixed sole, however, is less portable and does not serve occasionally when it is necessary, especially specialized sports shoes to buckle and it is not practical to carry classic shoes. A typical example is a trip on inline skates, when most of the time the user wears a shoe with wheels, but on these skates must not everywhere, typically to public transport, or. there is an increased risk of injury when overcoming various obstacles with this footwear (stairs, hills, uneven terrain). For the purpose of fastening, the user would need to carry solid footwear which is not storable, heavy and occupies space.

This disadvantage is partially eliminated by transport sleeves or socks with a non-slip layer, however, when wearing such socks the protection of the human foot against undesirable influences in the form of sharp edges, moisture, dirt etc. is not sufficiently addressed. Known solutions include eg patent CN 104432579 A or US 2015320139 A1 . In both cases, however, it is a textile solution having the character of a sock rather for wearing in domestic conditions.

The inventor's task was to develop a solution that would allow for easy and storable transport in the size of a rolled-up sock, while providing sufficient protection for the foot against moisture, abrasion, damage or dirt.

The essence of the technical solution

The above drawbacks are largely eliminated by a sock with a reinforced wear layer consisting of a sock body and an upper edge of a stretch fabric according to this technical

The solution is based on the fact that the sock body is formed in its sole part by a reinforced wear layer. The wear layer, consisting of one or more layers of a polymer blend or similar material (e.g., latex, nitrile, polyurethane or PVC) of different thickness and texture, has a toe front protection in the toe of the toe in the form of an increased height of the reinforced wear layer. In addition, the wear layer has a heel protection in the rear part of the foot. Achilles tendon in the form of increased height of this heel part of the reinforced wear layer. The increased height of the protective layer is also applied along the (edges) of the foot to isolate the foot from external influences. The sock with a reinforced wear layer preferably has an instep portion of the sock body formed of an elastic breathable material to provide sufficient comfort when moving and protecting the foot. The upper edge of the stretch fabric sock may further comprise a rubber non-slip band on its inner side in contact with the human foot.

A sock with a reinforced wear layer according to this invention has several advantages over the prior art. One of them is that it allows its user to transport easily and conveniently, which can be rolled into a roll like an ordinary sock. Combined with this first advantage, the second advantage is at the same time, despite all the low weight, almost full foot protection and the possibility of using a technical solution as a full-size shoe, which still gives the human foot enough freedom, protection, yet feeling close to barefoot. Thanks to the material applied to the reinforced wear layer, the sock has anti-slip and anti-abrasive properties.

Clarification of drawings

The technical solution will be explained in more detail by means of the drawing, in which Fig. 1 shows a sock with a reinforced tread layer showing its individual parts.

Example of technical solution implementation

Example 1

The sock with a reinforced wear layer consists of a sock body 1 consisting of a mixture of natural and man-made fibers, and an upper edge 4 of a stretch fabric, which is composed mainly of elastic man-made fibers with an admixture of rubber. The sock body 1 is provided with two layers of polymer blend in its lower sole. Thus, the layers as a whole form a thickened wear layer 2 on the sock body 1. In its rear heel part, the tread layer 2 is applied higher and forms a protection 6 of the heel, respectively. Achilles tendons. The reinforced wear layer 2 is also applied to the sides of the foot.

The instep part 3 of the sock body 7 and the sock body 1 are made of a stretch material of a mixture of natural or artificial fibers.

Example 2

The sock with a reinforced wear layer consists of a sock body 1 consisting of a mixture of natural and man-made fibers, and an upper edge 4 of a stretch fabric, which is composed mainly of elastic man-made fibers with an admixture of rubber. The sock body 1 is provided with one thick layer of polymer blend in its lower sole. After application, the layer is etched chemically to achieve a structured surface. The etched layer of the polymer blend as a whole forms a thickened wear layer 2 on the sock body 1. The thickened wear layer 2 is pulled in its front toe part almost to the instep part 3 of the sock body 1, where it protects the 5 toes of the foot. In its rear heel part, the tread layer 2 is applied higher and forms a protection 6 of the heel, respectively. Achilles tendons. The reinforced wear layer 2 is also applied on the sides

Example 3

The sock with a reinforced wear layer consists of a sock body 1 consisting of a mixture of man-made fibers and an upper edge 4 of a stretch fabric, which is made up mainly of elastic man-made fibers with an admixture of rubber. The sock body 1 is provided in its lower sole with one continuous layer of polymer blend to which, after application and drying, a second layer of polymer in the form of non-slip dots (drops) is applied. Thus, both applications of the polymer blend as a whole form a thickened wear layer 2 on the sock body 1. In its rear heel part, the wear layer 2 is pulled upwards and forms a protection 6 for the heel or the heel. Achilles tendons. Reinforced tread layer 2 pulled out at the sides of the foot. The instep part 3 of the sock body 1 is made of a stretch material of a mixture of natural or artificial fibers.

Industrial applicability

Sock with reinforced wear layer can be used in almost any wear instead of classic solid footwear, especially in situations where it is necessary to carry spare shoes or shoes for change (eg inline skating, cycling, climbing, etc.), or. where it is not necessary to wear classic solid shoes (in gyms, yoga and similar exercises, on the beach, etc.).
