Definitions

  • the invention relates to a barefoot shoe with bottom and shaft and with locking means for locking the shoe at the foot of a person wearing the shoe and the use of a shoe as barefoot shoe.
  • barefoot walking strengthens muscles, ligaments and joints, improves motor skills, promotes sense of balance and prevents injury. The spine and the rest of the body will benefit as well. Walking barefoot or walking barefoot strengthens the immune system, especially in cold weather. If foot damage is already present, barefoot walking can often correct and alleviate discomfort better than with orthopedic aids.
  • Barefoot walking is considered to be extremely healthy and desirable in many areas of daily life. Basically, one would therefore refrain from shoes, if there were not the risk of injury from lying around objects, rubbish, broken glass, sharp stones, bottle caps, insects, small animals od. Like.
  • One known such outdoor shoe which may be referred to as a sock rather than a shoe, has a dimpled rubber sole which is followed by a fabric upper.
  • This outdoor shoe proves to be problematic especially when used in the wet, since the rubber sole and the textile fabric stored moisture can not deliver as quickly as desired and the foot does not have sufficient support when wet.
  • This well-known outdoor shoe is not able to convey the desired barefoot feeling and thus rather unsuitable as a "barefoot shoe”.
  • swimming shoes are known, which firmly enclose the foot of the wearer with the right size selection. As a result of thin materials such swimming shoes leave a person wearing these shoes feel the ground well and also convey a secure feeling.
  • the disadvantage is that such a swimming shoes wearing person sweats heavily and also swimming shoes when using "on land” are not durable. In the event of moisture, water also accumulates in the swimming shoes and the feet not only stay moist, but literally wet. Also swimming shoes are therefore unsuitable for use as "barefoot shoes”.
  • an outdoor shoe with a sole made of grooved natural rubber and a shaft made of polyamide stretch fabric is known.
  • this outdoor shoe is disadvantageous that the feet sweat quickly and moisture that has penetrated can escape.
  • the sole of this outdoor shoe does not provide adequate support, especially on slippery surfaces. Overall, therefore, this outdoor shoe is not suitable for use as a "barefoot shoe”.
  • Kettenge- weave socks are typically used to protect against injury to the feet, especially in harsh working environments (eg when dealing with chainsaws), and are therefore not designed to be carried in the manner of a "barefoot" without further over and under shoes or socks become. Also, these allow - with respect to the fit only very coarse and not tight fitting - warp socks no fast movements - such as walking, running, climbing over long distances - to, as the loose, very heavy material would swing too much. Their application is therefore limited to the pure body protection while working in one place remaining.
  • a barefoot shoe is to be created, which encloses the feet of a person wearing the barefoot shoe fit and tight fitting and without the risk of injury in a quick change wet, dry, cold, warm, etc. feel. Accordingly, the shoe should be well ventilated and react quickly changing to environmental influences, adapt to the foot like a "second skin", be possible to use even in the cold season and sit firmly on the foot in any weather. Furthermore, the creation of pressure points, blisters, abrasions or the like should be avoided. loading Movements of muscles and tendons in the foot should not be obstructed by the barefoot shoe in any way. The foot should be reliably protected against injury and penetration of interfering foreign bodies should be avoided as far as possible.
  • the barefoot shoe should be as durable as possible, despite constant change between heat, cold, wet and dry. Furthermore, it is desirable that the static friction properties (so-called "grip") of the barefoot shoe are sufficient, even on variable substrates.
  • the barefoot shoe should be quick to clean and offer better hygienic properties than other so-called barefoot products.
  • the aim is that the barefoot shoe is lightweight and flexible and can be designed visually appealing.
  • the object is achieved by the use of a shoe with bottom and shaft and with locking means for locking the shoe at the foot of a person wearing the shoe whose bottom has wholly or partially of annular structures existing areas as Barefoot.
  • a barefoot shoe which has a bottom and a shank and locking devices for locking the barefoot shoe on the foot of a person wearing the barefoot shoe, and whose bottom consists entirely of ring structures or at least partially has exclusively consisting of ring structures areas arise for the person wearing such a shoe, especially when used in the "outdoor” - area, effects on the skin, which are comparable to a "real" barefoot or come close to this, since for the Wearer of the shoe the environmental influences, such as humidity, temperature (heat, cold), surface texture u. Like. Immediately noticeable.
  • the locking devices are at least partially provided in the regions of the shaft which are in the wearing state in the instep or instep region, a tight-fitting yet easily attachable and extendable shoe is created ,
  • the fact that the locking devices are located in the dorsal region is not detrimental to the barefoot shoe - in contrast to the known long-sock warp-knit socks - because the protection of the back of the foot is of secondary importance in a barefoot shoe.
  • the shoe in the dorsal region in particular have a larger opening in the manner of a ballerina shoe, in which case the locking means are formed so that the edge of the opening is acted upon in the manner of a tightening tension with an elastic clamping force.
  • the locking means may also be formed in the manner of known laces or in the manner of buckles or straps fixed with hook and loop fasteners.
  • the bottom consists only partially of ring structures.
  • parts of the floor for example in areas of the arch of the foot, which usually have no direct contact with the ground due to the arch anatomy of the sole of the foot, can be realized by means of other materials.
  • the advantages of the ring structures according to the invention and the advantages of conventional shoe materials can be combined with one another.
  • the locking means may also be provided in the dorsal region.
  • the ring structures are formed open, in contrast, for example, to vulcanized into a rubber layer ring structures od in the field of protective workwear as penetration protection for nails.
  • open ring structures may also include configurations in which, in addition to the ring structures, further substantially permeable fabrics, such as, for example, coarse mesh fabrics, are provided.
  • the barefoot shoe and the structure of the ring structures are designed such that environmental influences can act directly on the foot of a person wearing the barefoot shoe, ie, that the barefoot shoe and the ring structures are ergonomically designed so that the shoes are preferred by a user additional intermediate socks between the foot of the wearer - although the use of intermediate socks, as explained below, is possible - and can be worn without overshoe ,.
  • this results in the advantage of quasi-direct contact of the sole of the foot with the ground with excellent ventilation and faster drying and removal of particulate foreign matter such as sand and at the same time unimpaired protection against injury.
  • the bottom of the barefoot shoe consists entirely of ring structures, and the areas of the shaft adjoining the floor, in particular the toes in the front shoe area and the heel of the person wearing the shoe in the rear shoe area, are integral with the ring structures are formed of the soil and thus also consist of ring structures.
  • the advantages of the present invention are essentially achieved in that at least a portion of the bottom is formed in the form of ring structures and the entire barefoot shoe is designed such that these ring structure portions have an open and / or permeable interface surface. form between the sole of the foot and ground, ie, that the shoe can be worn comfortably without additional socks or overshoes.
  • the remaining parts of the shoe, ie the remaining parts of the bottom and the shaft - can - depending on the specific requirement profiles - either also consist of ring structures, or be made entirely or partially from other customary in the shoe area materials.
  • ring structures are understood to mean fine-meshed flexible surface elements as permeable rasters, which, when loaded by the weight of a person wearing the barefoot shoe, are rigid (surface-stable) and wrap around one another or central holding elements. Metal and / or plastic.
  • the rings of the ring structures may be round, angular (e.g., 4, 6, 8 corners) or oval in shape.
  • the bottom of the barefoot shoe in contrast to solid soles, can be adapted individually to uneven floors. This results in e.g. good holding properties even with problematic substrate conditions such. reached on roots in moist moss growth. Since the foot adapts to the ground due to the relatively small ground support surface of the individual rings of the ring structures and the relatively high weight of the person wearing the shoe with high specific pressure, for example, in moss vegetation on roots press the rings of the ring structures through to the harder wood , which - even when tilted - slipping is unlikely.
  • a person wearing the shoe immediately feels the properties of the ground, temperature differences and differences in humidity at every step.
  • the foot is still better protected by the ring structures from cuts and cuts than in conventional barefoot shoes.
  • Another advantage is that the barefoot shoe can be easily cleaned, for example by washing under running water. Experiments have shown that the barefoot shoe according to the invention does not lead to sore areas, abrasions or bruises on the foot, since the material is applied, with a precise fit However, no permanent friction or permanent pressure exerted on individual sites.
  • the barefoot shoe according to the invention is permeable to air due to the completely permeable grid structure of the ring structures and therefore well ventilated. Due to the flexibility of the ring structures, the area of the barefoot shoe that comes into contact with the substrate adapts perfectly to the respective substructure.
  • the foot can be protected from the cold by thin, arranged inside the barefoot shoe socks, for example, from chloropenic rubber or other suitable, for example, from orthopedic and rehabilitation technology known materials, if necessary.
  • a suitable material is the lining material designed for the care of diabetic patients with the product name Diatex of Erkodent Erich Kopp GmbH (DE).
  • an additional sock for example, made of chloroprene rubber or other suitable materials to pull the outside of the barefoot shoe. This may be useful in situations where the adhesion of the ring structures to certain, especially artificially created, soils, e.g. polished granite, to be improved without losing the additional massage effect.
  • the barefoot shoes according to the invention also have good slip resistance properties, in particular on grown soils, since rings of the ring structures are easily set up on each ground contact and thus the comparatively small contact area remaining with the substrate leads to a high, surface-pressure-preventing surface pressure.
  • the design of the rings of the ring structures, both in terms of ring connections and the number of rings can be chosen so that, for example, thorny brambles or stinging nettles have no chance to touch the foot of the person wearing the barefoot shoe.
  • dirt particles can basically get into the barefoot shoe, but they are "sifted" through the fabric interstices of the ring structures during the entry, so to speak, and pushed out again by the back pressure of the foot.
  • the ring structures used in the barefoot shoe according to the invention are durable and easily tolerate changes between hot and cold, dry and wet od. Like. After wet contact the foot is dry again after a few steps. When passing through a puddle of water, the foot of a person wearing the barefoot shoe is pleasantly cooled and is soon dry again. Due to the open structure of the ring structures and thus their continuity, the environmental influences desired in barefoot running thus act directly on the foot of the person wearing the barefoot shoe, as is otherwise the case only with true barefoot walking or walking.
  • the barefoot shoe according to the invention is flexible due to its ring structures and od for storage, transport od. Like.
  • the barefoot shoe can be brought into virtually any desired shape and occupies much less space than conventional shoes.
  • Suitable materials may be selected from the group of metals, metal alloys, (optionally modified) plastics, fibers or composites. Concrete examples of suitable materials are steel or steel alloys, aluminum or aluminum alloys, titanium / stainless steel or corresponding alloys, silver / gold, Brass or brass alloys, copper or copper alloys (including bronze), hard plastics, fiberglass, carbon fiber or aramids.
  • the rings can be welded or soldered. As far as the rings are made of plastic, they can be fused or glued.
  • the number of rings suspended in each other depends on the particular application and is variable.
  • the ring structure has a plurality of interconnected raster elements, wherein each raster element preferably has four rings each, which are mounted in a common connecting ring.
  • the individual grid elements are connected by the fact that the mentioned four or more rings are each mounted in different, as connecting rings or otherwise designed as the central holding elements further correspondingly formed grid elements.
  • Ring structures within the meaning of the present invention also include so-called metal ring braids or flexible structures referred to as so-called “flexible shed braids” in which a multiplicity of elements designated as “shed” or “capsules” are connected to one another via hinged rings.
  • the dandruff or capsules each have closed flat sides and hinged rings in edge regions of the dandruff or capsules.
  • four rings are each hooked into opposite edge regions and together with the respective scale or capsule form a grid element which is in communication with correspondingly formed further grid elements in that each of the four rings mentioned is in edge regions is hung by four more scales or capsules.
  • the dandruff meshes have through openings through which the environmental influences desired in barefoot walking can reach the foot of a person wearing the barefoot shoe.
  • capsules or scales with structures provided on the ground side can or can be used as a central holding element or as a central holding element.
  • the bottom of the barefoot shoe may, depending on the design, have areas with fewer rings or areas with additional rings of different orientation. Such measures can influence the "grip" behavior of the barefoot shoe.
  • Ring structures made of metal have the advantage of being particularly resistant to ring structures made of other materials.
  • Metal ring structures are particularly suitable for use in areas of high mechanical stress (e.g., changing terrains, hard soils, steep slopes, or the like). Metal ring structures protect against injury.
  • Plastic ring structures have the advantage of being lighter than metal ring structures and more flexible. Ring structures made of plastic are preferably used when it comes to applications with lower mechanical stress (meadows, beaches, soft ground, low risk of injury od. Like.). Barefoot shoes with ring structures made of plastic have a high wearing comfort.
  • Preferred dimensions of the rings of the ring structures provided according to the invention can be, for example:
  • Ring outside diameter between 2 mm and 7 mm; Wire diameter of the ring: between 0.4 mm and 1.25 mm.

  • the rings have a ring outside diameter of 4.0mm and a ring inside diameter of 2.9mm.
  • the wire diameter is 0.55 mm.
  • the shape and construction of the barefoot shoe according to the invention are variable: between the shape of a so-called footlet or a light ballerina shoe and the shape a high-necked, possibly additionally reinforced outdoor shoe, even in boot shape to over the ankle, many variants are conceivable. It is also possible to design the barefoot shoe in the manner of a simple, stretchable sock (with toe-pockets or without toe-pockets). Toe compartments, for example, make sense when the barefoot shoe special requirements (eg climbing requirements) are made.
  • the locking means for locking the shoe to the foot of a person wearing the shoe can be carried out in a conventional manner.
  • Barefoot shoes according to the invention can also have reinforcements and / or additional elements for increasing the grip (so-called "grip improvements"), and also elements for upholstery, insulation or the like.
  • the ring structures may be provided as locking devices, for example, spring-loaded locking hooks, by means of which a stepless lock in correspondingly attached eyelets and the ring fabric itself can be done.
