Definitions

  • the present invention relates to a flexible object, in particular a shoe insert, with a flat base body which is intended to be placed on a flat surface of an at least substantially rigid object, the base body having a first, load-bearing layer and a second material layer, which is one of the Associated sides of the base layer and whose thickness is smaller than the thickness of the base layer, and with an adhesion promoter, which is attached in places on the surface of the second material layer intended to rest on the rigid object.
  • This shoe insert includes a absorbent layer, which contains cotton-like material. There is a layer of fibers on the top of this absorbent layer, which prevents the foot of the insole user from coming into contact with the material of the absorbent layer. This is necessary because the material of the absorbent layer has a very low abrasion resistance.
  • the other surface of the absorbent layer is covered with a fleece or tissue, which are designed in such a way that they give the shoe insert the stiffness required for the use thereof.
  • the underside of this third layer of material is provided with an anti-slip covering. This anti-slip covering can completely or only partially cover the underside mentioned.
  • the object of the present invention is to specify a flexible object, in particular a shoe insert, in which it does not slip on a firm and flat surface. And if such a slip occurs, then this object should automatically get into its plane and correct position.
  • the object shown in perspective in FIG. 1 can represent part of a shoe insert.
  • the present subject matter can also form part of other items.
  • Such objects can be, for example, a textile fabric, compact plastic, glass, metal, minerals, fleece, felt, foam, leather, synthetic leather, etc.
  • Such objects can be intended to rest on a flat surface of an object, which can be made of leather, synthetic leather, wood, marble, stone, metal, glass, compact plastic or which is designed as a textile fabric. So that the description of the subject matter is easy to understand, it is set out below in connection with the use of the same as a component of a shoe insert.
  • This shoe insert has an absorbent layer 1, the thickness of which in the finished product essentially determines the thickness of this product.
  • the thickness of the absorbent layer 1 in the finished product is between approximately 1 mm and 5 mm.
  • the absorbent layer 1 expediently extends over the entire area of the shoe insert.
  • Loosely carded wadding or wadding wastes that are produced in the production of other wadding products can form the material of this absorbent layer 1.
  • the wadding can consist exclusively of cotton fibers or it can form a mixture of subordinate fibers.
  • this layer can contain cotton and rayon fibers which are connected to one another with the aid of a fiber made of a suitable material.
  • Such an adhesive fiber can be a synthetic fiber and it can in particular be a polyethylene fiber.
  • the absorbent layer can contain 70% cotton or viscose and 30% polypropylene fibers.
  • a stabilization layer 2 is assigned to the absorbent layer 1 and this stabilization layer 2 is located on that side of the absorbent layer 1 which faces the insole of the shoe.
  • the stabilization layer 2 is designed in such a way that it gives the shoe insert the rigidity required for pushing it into a shoe.
  • this layer 2 is designed so that it has an anti-slip effect when the shoe is worn.
  • the stabilization layer 2 is made of a fibrous material in which the fibers form several layers.
  • the material of this layer must be a sealable material. It can be a fleece or a tissue. If the layer 2 is made of a fleece, then it can advantageously contain vascular fibers. These fibers can be about 40mm long and their thickness can be 3.8 decitex.
  • the fibers of the fleece are connected to each other with the help of a binder. Such a mixture can contain 75% fibers and 25% binder.
  • the binder can be based on synthetic rubber.
  • this non-woven fabric 2 can also be made of 100% polypropylene. This material advantageously contains color pigments that make it easier to distinguish between the top and bottom of the shoe insert.
  • the fibers in the fleece of the stabilization layer 2 are arranged in such a way that they run parallel to one another.
  • Such one Fleece is also known as longitudinal layer fleece.
  • the direction of the fibers lying parallel to each other practically coincides with the longitudinal direction of the shoe insert. It may be advantageous if there is a non-zero angle between the direction of the fibers and the longitudinal direction of the shoe insert. This can be the case, for example, when slipping of the shoe insert at an angle to the longitudinal direction of the shoe or the same is to be prevented.
  • the stabilizing layer 2 can be made of a tissue.
  • the tissue should have a rough to wavy surface. Crepe paper, for example, can be used for such purposes.
  • the side or surface of the absorbent layer 1 facing away from the stabilization layer 2 is assigned a layer 3, which can also be referred to as a cover layer 3.
  • This cover layer 3 advantageously completely covers the upper side of the absorbent layer 1 and thus forms the upper end of the shoe insert.
  • the surface layer 3 is designed in such a way that it is permeable to foot sweat, but that it cannot be wetted by this liquid. Thanks to this training the cover layer 3 also forms, among other things, a spacer between the absorbent layer 1 and the foot of the shoe wearer.
  • the surface layer 3 is made of fibers which form at least one layer. These fibers must be made of a relatively tear-resistant material because the body weight of the user of the present shoe insert must be absorbed by these fibers, as will be seen from the following. In addition, the material of these fibers must be sealable.
  • the fibers of the surface layer 3 can form a fleece or a fabric.
  • the fleece of the cover layer 3 can be 100% polypropylene, whereby this layer or the fibers thereof can be colorless. In any case, this cover layer 3 should have a different color than the stabilization layer 2, so that the aforementioned optical or color distinction between the top and the bottom of the insole is easily possible. An easy or problem-free distinction between the two sides of the insole is necessary because only the underside of the sole has anti-slip equipment.
  • the base body 5 of the shoe insert has cutouts 6 which are made in at least one of the sides or surfaces of the base body 5.
  • cutouts 6 are made in at least one of the sides or surfaces of the base body 5.
  • Recesses from the two sides of the base body 5 are made in this.
  • These recesses can be designed as depressions or blind holes 7 or as holes or through openings 8. If the recesses 6 are designed as through holes 8, then these holes 8 should, among other things, allow or promote a flow of air across the shoe insert.
  • the depressions 7 made in the opposite sides of the base body 5 lie opposite one another. However, it is possible to implement these depressions in the opposite sides of the base body 5 in the plane of the base body 5 of the shoe insert (not shown). In such a case, the central axes of the recesses 7, which are offset from one another, do not coincide.
  • the cutouts 6 are produced in such a way that the layer material or the base body 5, which has the layers 1, 2 and 3, is guided between heated rolls of a calender.
  • the two rollers have projections, the height of which is approximately half the thickness of the shoe insert - higher projections, or the height of which is less than half of the thickness mentioned - lower projections.
  • the projections stand like spikes from the surface of the respective heated roller and they advantageously have the shape of a truncated pyramid.
  • This truncated pyramid has either a square or a rectangular base area and is connected to the roller over the larger base area thereof.
  • the mandrels are distributed on the surface of the respective heatable roller in such a way that they form patterns. If the cutouts 6 in the opposite sides of the base body 5 are to lie exactly opposite one another, then the calender rolls are driven synchronously in such a way that the central axes of the roll mandrels lying opposite one another coincide.
  • the end face of the truncated pyramid and at least a portion of the pyramid walls adjoining this end face penetrate into the layers 1, 2 and 3 of the base body 5.
  • the end face of the truncated pyramid pushes or pushes the material of layers 1 to 3 in front of this end face and brings it into the interior of the absorbent layer 1.
  • the fibers of the stabilization layer 2 and the cover layer 3 are thermoplastic, the fibers or sections thereof in the effective area of the respective mandrel become after a corresponding heating, by which sections of the side walls of the truncated pyramid adjoining the end face of the projection are pulled to the side and at the same time into the depth of the laminated body 5.
  • the thickness of these drawn sections 9 of the outer material layers 2 or 3 can be reduced if the depth of the recess 6 is greater than the diameter of the outer mouth of this recess 6.
  • These runners 9 are located in the interior of the laminated body 5, they form a lining of the side walls of the recesses 6 and the thickness of this lining 9 can decrease with the increasing depth of the recess 6.
  • the shorter or lower roll mandrel leaves a depression 7 in the laminated body 5, which also has a bottom 10 in addition to the side walls 9 mentioned.
  • the fiber material of this recess floor 10 forms a coherent layer with the fiber material of the side linings 9.
  • This base 10 is formed by the material of the outer layers 2 and 3, which has pushed the end face of the truncated pyramid in front of it.
  • the fiber material of the absorbent layer 1 is compressed between the bottoms 10 of the mutually opposite depressions 7.
  • the thickness of this fiber layer can be selected by selecting the height of the shorter roll mandrels or by changing the distance between the calender rolls.
  • Two opposing longer roll mandrels create a hole 8 in the laminated body 5.
  • the end face of the roll mandrel which has the shape of a truncated pyramid, breaks through the outer fiber layers 2 and 3 during penetration into the layers 1 to 3.
  • the remaining material of the outer fiber layers 2 and 3 as well as the material of the suction layer 1, which was initially still between the roll mandrels, is displaced from the space between the mandrel end faces when the end faces of the opposite mandrels meet and pushed to the side, where it forms material accumulations 11 . Since the material of at least the outer layers 2 and 3 is also sealable, the inner edges of the linings 9 are welded together in the opposite recesses 6 and the material accumulations 11 mentioned form the weld seam.
  • the inner wall of the hole 8 comprises two wall sections 9, each of which has the shape of the shell of a truncated pyramid.
  • the narrower parts of these truncated pyramids face one another and are connected to one another by means of the weld seam 11. Accordingly, the diameter of the hole 8 is the smallest approximately in the middle of the thickness of the base body 5.
  • the fibers of the outer layers 2 and 3 have a length of, for example, 4 cm.
  • the diameter of the mouth of the respective recess 6 is approximately 1 mm and the distance between two adjacent recesses 6 is only a few millimeters.
  • a practically undeformed section 12 or 13 of the relevant outer fiber layer 2 or 3 lies between two cutouts 6, which are made in the base body 5 from one of the outer fiber layers 2 or 3.
  • the recesses 6 are designed only as depressions 7 with a base 10, then the end parts of the bent fibers of the outer fiber layers 2 and 3 are held in the region of the base 10 mentioned. This is because they were compressed and welded together in the area of the floor 10 under the action of heat and pressure.
  • the recesses 6 are not only in a row (FIG. 2) but are distributed over the surface of the base body 5 (FIG. 1), the approximately arcuate sections 12 and 13 of the surface layers 2 and 3 run practically in every direction. This results in a skin 15 on the respective surface of the base body 5, which is three-dimensional and which increases the rigidity of the base body. Between the skins 15 on the two sides of the base body 5 is the material of the absorbent layer 1, which is enclosed between them and in some cases also pressed together. This improves further the rigidity of the base body 5.
  • the subject has active ingredients. These are in the form of a liquid and this liquid is enclosed in microfine gelatin capsules 16 or the like. These capsules 16 can be distributed over the surface of the cover layer 3, where they can be exposed to a direct influence on the one hand of body heat and on the other hand of foot pressure. Individual capsules 16 can also easily be located in the cutouts 6. Such capsules 16 come later to release their content, which extends the duration of effectiveness of the substances released.
  • the capsules 16 can also be accommodated in the top layer 3 or even in the layers 1 and 2 below. Under the influence of body heat and changing loads on the shoe insert, the capsules 16 are blown up and the contents thereof are released. Since all capsules are not blown up immediately, the active ingredient can be released over a longer period of time.
  • the active ingredient can be a fragrance or a specific active ingredient, such as a fungicide, antiperspirant, bactericide or the like.
  • One of the sides or surfaces 21 of the base body 5 of the flexible object is for resting on a flat surface 17 of an at least substantially rigid object.
  • This side 21 of the flexible object is provided with an adhesion promoter or adhesive medium which is only applied in places or regions.
  • the material of the adhesion promoter forms islands 25, which are embedded in the adhesive side 21 of the base body 5 of the object.
  • the islands 25 have a base 26 and a summit 27.
  • the base 26 is located below the surface of the base body 5 or the stabilization layer 2 and it enables the island 25 to be firmly anchored in the material of the base body 5.
  • the islands 25 advantageously have a circular circumference.
  • the diameter of this circumference is about 1mm or less.
  • the islands 25 can have the shape of a hemisphere or a spherical cap.
  • the height and shape of the island 25 is chosen so that it can be well anchored in the material of the base body 5.
  • the hemispherical or cap-shaped island 25 meets this requirement well because the greatest width of the base 26 of such an island 25 lies in the area of the base 29 of the base 26.
  • the stabilization layer 2 can have a thickness of a few tenths of a millimeter. In such a case, approximately one half of the height of the hemisphere 25 can represent the base 26 and the other half of the hemisphere, which protrudes from the stabilization layer 2, the tip 27. Since the height of the base 26 is greater than the thickness of the stabilizing layer 2, the lowest and widest section 29 of the base 26 is even embedded in the material of the absorbent layer 1. Since the side walls of the hemisphere or the spherical cap, which extend from the base surface 29, converge towards the apex 28, the material of the absorbent layer 1 and of the lower outer fiber layer 2 can rest on or on these side walls and for good holding of the island 25 in the base body 5 contribute.
  • Suitable measures ensure that the material of the adhesive medium penetrates into the material of the base body 5 so that the anchoring of this adhesive medium in the material of the base body 5 is greater than the later adhesion of the islands 25 to the object 17.
  • the adhesion promoter is made of a material that remains practically permanently sticky even after setting, whereby this material can contain latex.
  • the composition of the material of the adhesion promoter is set in such a way that the cohesion in the material is greater than the adhesion of this material with regard to of the material of that object 17 on which the flexible object 5 is intended to rest.
  • the material of the adhesion promoter can contain a dye or / and fragrances and other active ingredients.
  • the material of the adhesion promoter 25 can contain plastic compounds such as nitrile latex, acrylic latex, styrene latex, etc. This material can have the form of a paste or powder or a film, and it is applied or introduced onto the base body 5 using suitable technologies.
  • This mixture results in a paste with a viscosity of about 10 to 11 Pas (100 to 110 poise), which is printed as a pattern on the base body 5 using a stencil printing machine. After drying at about 140 degrees Celsius, the water of the paste is evaporated and a grid of slightly sticky islands 25 remains. These islands 25 represent the actual adhesion promoter.
  • the distribution of the islands 25 from the adhesive material over the surface of the base body 5 can be calculated using a computer in such a way that it is correct for the respective application. This is possible because the adhesive material forms points or only small areas, islands 25. With the help of a calculation, the intensity of the adhesion of the object 5 to an object 17 can be set precisely by a suitable choice of the number of islands 25 per unit area of the base body 5 according to the respective purpose. This was previously not possible because the adhesive surface was covered with the material of an adhesion promoter. The only change in the adhesiveness was possible only through variations of the adhesive material, which was very cumbersome.
  • the material of the bonding agent does not have to be changed, but it is sufficient according to the present invention to change the number and / or the size of the islands 25. Such changes can be carried out without any problems in the printing press in question.
  • the islands 25 make it possible to achieve different adhesive strengths in certain areas of the same object, which was also not previously possible.
  • the flexible object shown in perspective in FIG. 1 has the middle layer 1, the lower layer 2 and the Cover layer 3 of the sole according to FIG. 2.
  • the underside of the second or lower layer 2, which is thinner than the first layer 1, is provided with the islands 25 described.
  • Such a base body 5 is provided with the cutouts 6, which have also been described. These recesses 6 are designed as holes 8 which pass through all three layers 1 to 3. However, it goes without saying that these cutouts 6 can also be designed only as depressions 7 or that such a base body 5 can have both depressions 7 and holes 8.
  • the object has a whole number of cutouts 6, which form patterns. 1 and 3 a pattern is shown which contains two types of recesses 6, actually holes 8.
  • the two types of recesses 6 have a rectangular cross section.
  • the length of the first recesses 61 is smaller than the length of the second recesses 62.
  • the width of the recesses 61 and 62 of the two types is approximately the same.
  • the longer cutouts 62 form parallel rows 32 in the base body 5, which are at a distance from one another.
  • the cutouts 62 in the respective row 32 are oriented such that the longer sides 33 thereof run parallel to one another.
  • the distance between two Recesses 62 lying next to one another are larger than the shorter side 34 of the cutout 62.
  • the cutouts 62 in the adjacent rows 32 are arranged offset to one another such that one of the cutouts 62 of the one row 32 is practically in the middle of the distance between two adjacent cutouts 62 the adjacent row 32.
  • the shorter recesses 62 likewise form rows 35 which run parallel to one another and are at a distance from one another. In each case one of these rows 35 lies between two rows 32 with the longer recesses 62, so that these two types of rows 32 and 35 alternate with one another.
  • the longer sides of the shorter recesses 61 lie obliquely to the longitudinal axis L of the respective row, the longitudinal sides closing different angles with the longitudinal axis L of the row 35.
  • the angle between the longitudinal side of the recess 612 and the longitudinal axis L is only 45 degrees.
  • a cutout of the second type ie 612, so that these two types of cutouts 611 and 612 alternate with one another.
  • the shorter recesses 611 and 612 of a row 35 are oriented and arranged with respect to the longer recesses 62 of the two immediately adjacent rows 32 such that the long sides of the shorter recesses 611 and 612 run parallel to a line which the end parts of the staggered to each other connects longer recesses 612 of the adjacent rows 32.
  • One end part of two mutually adjacent, longer cutouts 62 in one of the adjacent row 32 are each assigned two shorter cutouts 611 and 612 of the row 35 at one end, which converge with increasing distance from the longer cutouts 62.
  • the end portions of these shorter recesses 611 and 612 which are closer to one another are then assigned to one end of one of the longer recesses 62 from the row 32 which lies on the other side of the row 35 with these shorter recesses 611 and 612.
  • hexagonal patterns are formed in which two adjacent, longer and rectangular cutouts 62 form two longer sides of a hexagon.
  • a pair of concurrent and shorter recesses 611 and 612 is assigned to the end parts of these longer recesses 62.
  • An important feature of the present invention resides in that the islands 25 made of an adhesive material on the underside of the object are located only in those areas of the base body 5 which lie between adjacent cutouts 6 in the base body 5. This is shown in FIG. 3, in which a section of the object according to FIG. 1 is shown in a top view.
  • the material 5 provided with adhesive medium 25 is only partially covered.
  • the base body of the object therefore remains permeable to air and moisture if it was previously.
