Definitions

• the invention relates to a method for releasably attaching an object to a surface, the object being fastened by means of two flat structures coated on one side with a pressure sensitive adhesive, the flat structures on the other side having corresponding connecting elements for the positive connection of these other sides to one another and the fabrics are in particular formed as tapes.
• the surface mentioned is a vertical wall, but it can also be horizontal or sloping surfaces such as ceilings or sloping walls.
• Such a system of tapes for carrying out this method is known as "tesa Velcro tape self-adhesive" from Beiersdorf AG.
• the fastening system consists on the one hand of a so-called hook tape which is provided on one side with a pressure sensitive adhesive and on the other side with a large number of hooks which are usually used for Velcro fasteners.
• the other band of this fastening system is in turn coated on one side with a pressure sensitive adhesive, but on the other side carries a fleece into which the hooks of the other band can engage.
• the hook tape and the fleece tape with their Velcro connection sides are placed on top of one another and pressed together.
• the adhesive side of the loop tape After removing a cover paper from the adhesive side of the loop tape, the adhesive side of the loop tape is glued to the object to be fastened and pressed firmly. After peeling off the cover paper on the adhesive side of the hook tape, it is glued to the cleaned surface and pressed firmly.
• the object is thus attached to the surface on the one hand, but can be removed from the surface again by detaching the two bands from one another.
• a disadvantage of this known fastening system and method is that after the attached object has been detached, the hook band remains on the surface, which is not only unsightly, but is also impractical, since this surface area can no longer be used for other purposes. If the hook band is also to be removed from the surface, it is necessary to first detach a small part of one end of the hook band so that the user's hand can grip the hook band at all and then pull it off the surface.
• Adhesive strips and corresponding fastening methods are also known, which are available from Beiersdorf AG under the trade names "tesa Power Strips” or "tesa Poster-Strips".
• the only difference between the two types is the strength of the pressure sensitive adhesive and the geometric shape.
• the approximately 2 to 3 cm long and 2 cm wide strips essentially consist of a very elastic pressure sensitive adhesive.
• the area of one end is covered on both sides with a cover film.
• the entire surface of both sides is covered with a further protective paper in a manner known per se.
• a strip is removed from its protective paper and glued to the back of the object to be fastened.
• the cover films on both sides of one end of the strip cannot be removed.
• the back of the object is glued to the surface and pressed on.
• the user's fingers grasp the end of the strip covered by the cover film and pull in the direction of the longitudinal axis of the strip. Due to the high elasticity of the Adhesive material increases its length and shortens its width, whereby the pressure sensitive adhesive detaches from the wall. It is also important in this process that the strips are always drawn parallel to the surface. If you pull at an angle, there is a risk that the strip will tear.
• the fastened object can be detached from the wall without residue and without destruction, but a great deal of effort is required to detach it.
• the object has been glued to the surface for the first time, it is no longer possible to easily correct the position of the object. Such a correction is often desirable in order to align pictures, posters etc. straight on a wall.
• a tape coated on one side is also known under the trade name "Duotec" from Binder.
• the band has on the other side mushroom-shaped projections which extend vertically outwards from the surface of the band. These projections are at such a distance from one another and such a geometry that when two pieces of the tape are placed one on top of the other with the adhesive sides facing outwards, the mushroom-shaped projections engage in the manner of a Velcro fastener.
• the special thing about this tape is that the corresponding connecting elements do not have a different shape in this case.
• the invention is therefore based on the object of developing a method of the type mentioned at the outset, which enables detachable fastening of the object to the surface and residue-free and non-destructive detachment of the object and of the flat structure, which does not require any great effort.
• the attached object should be able to be aligned on the surface in a simple, quick and problem-free manner.
• the fabric can have any shape, but the shape of a band is preferred.
• the fabric is already pre-folded by the manufacturer, so that the user only has to glue the sides, which are only on the outside, coated with pressure-sensitive adhesive, on the one hand to the object and on the other hand to the surface.
• the order of sticking does not matter. Usually, however, you first glue the fabric to the back of the object and only then to the surface. But the reverse order is also within the scope of the invention.
• volume For the sake of simplicity, the following is referred to as a volume, without the invention being restricted to this special geometric shape.
• the method according to the invention offers a considerable advantage over the known prior art mentioned above.
• the handle can be completely covered by the object, since the attached object can be folded away from the wall to detach the object so that the "handle" is accessible, so that this handle does not necessarily have to protrude beyond the attached object.
• a two-part object having a rail can also be pushed apart. But due to the handle provided with the cover film, a considerable part of the adhesive surface is lost.
• Another disadvantage which does not occur with the object according to the invention, lies in the problems with the handling of the said adhesive strip provided with a handle.
• the consumer is not aware that he should not remove the cover film of the handle. Since the consumer is used to remove protective films from adhesive strips, it is therefore more common that he also removes the cover film from the handle, so that the actual advantage of the handle, namely to be a handling aid when detaching, is lost.
• the method according to the invention enables the object already glued to the surface to be adjusted.
• the object is folded away from the wall at a small angle, the corresponding connecting elements detaching from one another, the object is adjusted and finally pressed onto the surface again, the said connecting elements intermeshing again and fixing the object in the selected position on the wall ,
• the corresponding connecting elements mentioned can be designed differently.
• the corresponding connecting elements consist of hooks and loops of a Velcro connection.
• the corresponding connecting elements can also consist of mushroom-shaped pins, as have already been mentioned above in the explanation of the prior art, and loops.
• the thickened ends of the mushroom-shaped lugs engage in the loops.
• the two corresponding connecting elements are constructed in the same way and in particular consist of mushroom-shaped pins.
• the connection is achieved similarly to the well-known volume with the trade name "Duotec" from Binder.
• belts made of material which is formed into waves arranged in parallel and 180 ° out of phase. A connection is obtained by pressing wave crests with a precise fit into wave valleys. Seen from above, perpendicular to the direction of the waves, there are webs on the wave crests or valleys that can be angled relative to the band plane and thus prevent accidental separation of the band parts that are connected to one another.
• the other side of the band carrying the two different types of connecting elements is divided in two in the transverse direction and in particular divided into two halves of equal size, one area being one type of connecting element and the other Area which has a different, corresponding type of connecting elements.
• the two different types of connecting elements are applied in a certain pattern on the mentioned side of the band.
• This can be a stripe or raster pattern.
• the band halves are folded together in such a way that connecting elements of the same type lie on one another, the object is not fixed. Such a possibility could be advantageous in certain cases.
• a statistical distribution of the different connecting elements is also possible.
• pressure-sensitive adhesive is used at least on parts of the inner side of the tape, the adhesion of the inner tape parts to one another not exceeding 50% of the adhesion of the outer pressure-sensitive adhesive to the substrates object and wall.
• the invention relates to a flat structure, in particular adhesive tape, for releasably attaching an object to a surface, one side of the flat structure being coated with a pressure-sensitive adhesive and the other side having at least one type of connecting element which is of a different, corresponding type of Connection elements is capable of positive connection.
• adhesive tape is known under the trade name "tesa Velcro tape self-adhesive" from Beiersdorf AG.
• the other side of the flat structure of the type mentioned has both corresponding types of connecting elements.
• These types of fasteners can e.g. B. are hooks and loops of a known Velcro connection.
• the corresponding connecting elements can be designed in different ways.
• the corresponding connecting elements consist of hooks and loops of a Velcro connection.
• the corresponding connecting elements consist of mushroom-shaped pins and loops, as has already been stated above.
• the distribution of the two different types of fasteners on the other side of the belt can vary depending on the requirements.
• it is preferred that the other side of the band is divided in two in the transverse direction and in particular is divided into two halves of equal size, one area having one type of connecting element and the other area having the other corresponding type of connecting element. The advantages of such an arrangement have already been mentioned above.
• the fabric has an elastic support.
• the tape can be removed by pulling at an angle to the wall of> 90 °. It is also possible that the "handles" known from the prior art for these adhesive strips are attached, if one is willing to accept the associated disadvantages. In this case the tape can be removed by pulling parallel to the wall.
• Pressure sensitive adhesives which are also called “pressure sensitive adhesives” and are abbreviated to "PSA" are adhesives that remain permanently sticky and tacky in solvent-free form at 20 ° C and adhere immediately to almost all substrates with low substrate specificity and light pressure.
• Pressure sensitive adhesives are used almost exclusively for coating substrates, e.g. B. paper or foil tapes, adhesive labels or self-adhesive decorative foils used.
• the actual adhesives are applied to the carrier in the form of solutions, dispersions or melts. Low-viscosity, solvent-free, reactive systems (polyurethane systems) are also used for this.
• the pressure-sensitive adhesive layer is present as a thin film on the carrier and is coated with suitable anti-adhesive materials, e.g. As silicone paper or siliconized polyethylene film covered. Sometimes you apply the pressure-sensitive adhesive to the cover material and transfer the pressure-sensitive adhesive film formed to the actual carrier in a reverse process.
• polyacrylic acid esters, polymethacrylic acid esters, polyvinyl ethers and polyisobutene types are also frequently used, likewise mostly in combination with resins.
• Silicone resin pressure sensitive adhesives are also known for special applications.
• the dispersion pressure sensitive adhesives are primarily based on dispersions of polyacrylic acid, eg. T. also built on special vinyl acetate copolymers, with resins usually being added here too.
• hotmelt PSAs mainly use two polymer bases, ethylene-vinyl acetate copolymers and styrene-butadiene or styrene-isoprene block copolymers, which are also referred to as thermoplastic rubbers.
• a pressure-sensitive adhesive is made up of a high-polymer base resin, which determines the cohesion property and the specific adhesion, and tackifying resins (so-called tackifiers), whereby the tackifying resin can also be replaced by low-molecular-weight portions of the base polymer in some systems.
