Description

  The present invention relates to a cover for a shoe insole, which consists of a single-sided closed tube made of elastic fabric.

  The use of insoles is known to improve in-shoe comfort and improve hygienic conditions. Insoles are also used to keep the cool air acting on the sole from the floor away from the foot. Known insoles are made from very different materials, for example leather, plastic or cork. Furthermore, the insole can be manufactured from a combination of different materials. Furthermore, it is known that the insole is provided with layers of different materials on one or both sides. Therefore, for example, in order to protect against cold, it is known to form an aluminum layer on the lower surface of the insole, whereas on the surface of the insole a layer made of textiles is known.

  In particular, insoles with holes, for example, are known to provide improved ventilation within the shoe to improve the pneumatic environment within the shoe. The use of insoles with activated carbon to improve the hygiene of shoes is known. Furthermore, the production of insoles made of composite materials is known. The composite material comprises, for example, surface active means or deodorizing means or consists of a disinfectant or PH buffer that improves shoe hygiene.

  Based on the prescribed properties of the composite material, the use of insoles gives satisfactory results. However, a weakness in using known insoles is that known insoles are not universally usable based on their shape and size. Furthermore, because the insole is based on a natural degradation process and loses effectiveness over the period of use, the air and hygienic environment within the shoe is exacerbated despite the use of the insole.

  In order to improve the effect of the known insole, the insole can be made washable in order to rinse out the contained bacteria and the like from each shoe, depending on the material forming the insole. However, this significantly accelerates the degradation process. Furthermore, it takes time to handle. This is because, for example, the drying process of the sole sometimes takes time.

  The problem is that it appears in all areas of use of the shoe. However, the problem is particularly serious when different users use the same shoes, particularly when ski shoes, skate shoes or bowling shoes are rented, for example. Here, the known insole cannot guarantee that the shoe is completely hygienic whenever the shoe is handed over to a new user. In addition, sanitary problems occur particularly in sports where shoes are used without wearing socks, as is the case with track and field athletes.

  Therefore, the present invention provides a countermeasure. The object of the present invention is to improve a cover for a shoe insole of the type mentioned at the outset in order to improve the air activity and hygienic properties in the shoe easily and at the same time very effectively.

  In order to solve this problem, in the configuration of the present invention, the cover is made of a single-sided tube made of an elastic fabric, and the cover has an opening.

  The present invention provides a cover for a shoe insole that contributes to a clear improvement in the climate and hygiene within the shoe. Since the cover is formed in a tube shape and is elastic, the cover 1 is optimally adapted to the shape of the insole. Therefore, the cover can also be used for shoes such as athletic sports shoes that require extremely high fitting accuracy.

  Further, the cover provides an advantage that each can be easily put on the insole. After use of the shoe, the cover is removed from the insole and can be washed in a conventional manner. This clearly improves the hygiene in the shoe. Furthermore, based on the material, the drying time is clearly reduced compared to a washable insole so that, for example, a cover washed at night can be used again the next morning. This provides a significant improvement with respect to comfort in terms of the insoles washability compared to insoles with air or hygiene improving properties.

  Further refinements and configurations of the invention are described in the dependent claims.

  A cover for an insole of a shoe according to the present invention is composed of a tube made of elastic fabric and closed on one side, and the cover is provided with an opening.

  The cover of the invention advantageously has its opening surrounded by an elastic band.

  In the cover of the invention, the fabric is advantageously made from yarn.

  The cover of the invention advantageously has the property that the yarn reduces friction.

  In the cover of the invention, the yarn advantageously has an antifungal effect.

  In the cover of the present invention, the yarn advantageously has an antibacterial effect.

  The cover of the present invention is advantageously provided with a functional surface on the side facing the foot.

  The cover of the invention advantageously has pile yarns whose functional surfaces are arranged in a pile.

  In the cover of the present invention, the pile yarn is preferably a silver yarn.

  In the cover of the invention, the pile yarn preferably has a core made of polyamide, which core is surrounded by a layer made of silver.

  The cover of the invention is advantageously provided with at least one air passage in the functional area.

  The best mode for carrying out the present invention will be described in detail with reference to the drawings.

  The cover 1 selected as an example is used to cover the insole 2 of a shoe (not shown). The cover 1 is made of an elastic fabric 11 and has the shape of a tube closed on one side. Thereby, the opening 3 is formed. This opening 3 is surrounded by a band 4. The band 4 is also elastically configured in this embodiment.

  The material used for the cover 1 can be selected virtually arbitrarily. The most important requirement for the material of the fabric 11 or the yarn forming the fabric 11 is that the fabric 11 can expand and contract. As a result, the cover 1 adheres well to the insole 2 and wrinkle formation is avoided when a shoe equipped with the insole and the cover is worn. In addition, yarns that reduce friction, for example Dynema or PTFE, can be used to prepare the fabric. This significantly reduces the risk of skin irritation or foam formation. Furthermore, it has proven to be advantageous if the fabric 11 of the cover 1 consists of very fine fiber yarns. The ultrafine fiber yarn is advantageously made of polymer fibers. It is also possible to use polyamide fibers, aramid fibers or acrylic fibers.

  The risk of foot diseases such as fungal infections can be reduced by using antibacterial or antifungal threads. For this, in particular yarns made of silver or copper or yarns coated with silver or copper are suitable.

  The opening 3 has a smaller diameter than the narrowest part of the insole 2. As a result, the opening 3 is not affected by the arrangement form of the opening 3, and a tensile force is applied to the fabric 11 in the covered state. Therefore, the opening 3 exists in any case based on the elastic configuration of the fabric 11. The tension of the cover 1 is reinforced. In the present embodiment, the opening 3 is placed on the surface of the insole 2 facing the ground, that is, the area of the heel on the lower surface in the covered state. This position is particularly advantageous here as it also excludes any loss of comfort here. Since the cover 1 can be configured differently, the opening 3 is arranged in another area of the insole 2. In this case, however, care must be taken that the rolling via the footpad is not impaired.

  The band 4 surrounding the opening 3 is configured in the form of a cuff in this embodiment. The band 4 is dimensioned relatively wide and thus has a high tension. At the same time, the band 4 is made very thin, so that the hindrance to comfort is avoided.

  A functional surface 5 is provided on the surface of the cover 1. This functional surface 5 may be configured differently and serves to improve the comfort or characteristics of the cover 1.

  In this embodiment, the functional surface 5 has a yarn forming a pile arranged in a pile shape, that is, a pile yarn 6. These pile yarns 6 extend over the entire surface. In a variant of the exemplary embodiment, the functional surface 5 may only partially comprise the pile yarn 6. For example, the toe area can be left free.

  The pile yarn 6 forms the surface of “Ring”. This configuration can also be referred to as a “loop”. The processing is performed, for example, by edging (Kanten), whereby the pile yarn 6 is formed into a wrinkle. The wrinkled shape of the pile yarn 6 provides a relatively tight surface when weaving into the fabric on the side facing the skin. As a result, about 80% of the foot sole is in contact with the pile yarn 6. A plurality of small piles in principle behave like a microscopically small file, so that dead skin cells can be scraped without damaging live skin cells. Thus, bacteria in the foot are removed from the medium. The scraped dead skin cells fall between the piles so that contact with the foot no longer takes place. When the cover 1 is washed, dead skin cells are immediately removed from the functional aspect.

  The pile yarn 6 is a silver yarn in this embodiment. These silver threads have a core 61 made of polyamide. The core 61 is surrounded by a layer 62 made of silver (FIG. 4). The core 61 is practically inelastic and is woven into the yarn forming the fabric. The coating of the yarn 6 forming the pile is preferably effected by electroplating. Layer 62 may be made of copper, gold, polytetrafluoroethylene, or the like in the variation of this embodiment. Different effects can be achieved by different configurations of layer 62. For example, an antifungal effect can be obtained with copper. In contrast, a layer made of polytetrafluoroethylene reduces the friction of the cover.

  Since the layer 62 is completely closed, the pile yarn 6 cannot absorb moisture such as sweat. Rather, sweat is sent in the direction of the fabric. Accordingly, the woven fabric or the yarn forming the woven fabric has air active properties. Therefore, the woven fabric or the yarn forming the woven fabric can contain moisture and foreign matter. This provides a substantially closed dry surface on the surface of the cover 1. This surface provides a much more comfortable wearing sensation. At the same time, the fabric prevents sweat from penetrating into the insole. This provides insole protection while preventing the insole from contributing to the deterioration of air and hygiene in the shoe due to absorbed moisture.

  Further, at least one air passage 7 is provided on the functional surface 5 of the cover 1. This air passage 7 contributes to the improvement of the air in the shoe. The air passage 7 enables air circulation in the shoe. During this air circulation, air can pass through the plurality of air passages and below the foot sole. As a result, very good ventilation of the footsole is achieved. Due to the movement of the foot in the shoe itself that provides the pumping effect required during exercise, dirty or moist air can be discharged even under the foot via the air passage 7.

  In this embodiment, three air passages 7 are provided. By these air passages 7, the pile-like configuration of the functional surface 5 is blocked. The air passage 7 can be formed by simply blocking the (high pile) pile, but can also be formed from an air-regulated mesh fabric. If the thickness of the mesh knitted fabric approximately corresponds to the thickness of the functional surface 5, a constant surface is provided. This effectively affects the comfort.

  In the variant of this embodiment, the air passages 7 can also be arranged radially. This arrangement of the air passages 7 provides a wide area of the functional surface 5 so that moisture can be carried out from the entire tread area. In this case, the width and length of the air passage 7 can usually be freely selected. The length and number of the air passages 7 are variable. By increasing the length or width of the air passage 7 or increasing the number of the air passages 7, the air that can be conveyed can be improved.

  A slip-resistant surface can be provided on the lower surface of the variation of this embodiment. The anti-slip surface is in contact with the shoe when the cover 1 is covered, thus preventing the insole 2 with the cover 1 from slipping in the shoe.
