Definitions
- the invention relates to a floor carpet laying system with a carpet which forms the usable surface with its front side and an anchoring means which can be fastened to the floor and which has hooking elements projecting upwards which come into hooking engagement with the back of the carpet facing away from the pile side.
- a floor carpet laying system of this type is already known from EP 0 321 978 B1.
- the back of the carpet has loop elements which project beyond the base of the goods and with which hooks of the anchoring means which can be fastened to the floor come into engagement.
- the invention has for its object to provide a floor carpet laying system that ensures an improved anchorage between carpet and floor.
- this object is achieved according to the invention in that the back of the carpet facing the anchoring means is formed by a loop-free material and in that a micro-adhesive fastener with hooking elements in the form of stems with end-to-end thickening is provided as anchoring means that get caught with the loopless back of the carpet.
- a micro-adhesive closure that is particularly well suited for the system according to the invention is known from DE 196 46 318 A1. Depending on the product base of the carpet to be laid, ie depending on the structure of the back, a micro-adhesive fastener with a thickness of the carrier of the hooking elements of 0.1 to
- the thickening of the stems of the interlocking elements can have the shape of mushroom heads or plate-shaped heads, the heads being preferably provided with concave depressions on their top.
- a method for the particularly simple production of micro-adhesive closures with such hooking elements is proposed in German patent application 198 28 856.5.
- the indentations of the heads can be provided with an adhesive which brings about an additional connection to the back of the carpet, for example by doctoring.
- the back of the carpet can be provided with textile materials in the form of felts or nonwovens, also loose leno fabrics or smooth knitted fabrics, and non-woven textiles (non-woven materials).
- Fig. 1 shows a schematically simplified and broken drawn
- FIG. 1 is a perspective, greatly enlarged view of a
- Micro-plastic fastener part a single interlocking element being shown even more enlarged and cut;
- Fig. 3 is a view corresponding to Fig. 2, wherein depressions on the top of the heads of the hooking elements are provided with adhesive, and
- FIG. 4 shows a top view of the loop-free back of the carpet of FIG. 1 that has been broken off and drawn into an approximately natural size.
- FIG. 1 shows an enlarged, schematically simplified representation of a section of a floor carpet with pile elements 1 of a conventional type which extend upwards from a connecting layer 3 and form the pile side of the carpet which serves as a usable area.
- the back 5 facing away from the pile side is formed by a loopless material.
- Materials that give the carpet structure a certain stiffness, directional stability and cut resistance can be used. These can be felts or nonwovens, which get their mechanical cohesion through tufting processes and are glued to the connection layer 3 of the carpet. Loose leno fabrics or smooth right / left knits and other so-called non-woven materials are also suitable for this.
- FIG. 2 shows a section of a strip of a microplastic adhesive fastener 7, as shown in DE 196 46 318 A1.
- a film-like carrier 9 is formed with stems 1 1 protruding from the upper side thereof
- Carrier 9 from about 0.1 to 0.5mm. Other packing densities and / or thicknesses of the carrier 9 can of course be considered depending on the particular circumstances.
- the thickened heads 13 of the stems 11 are deformed into a mushroom or plate shape with a concavely curved upper side, so that a depression 15 is formed within the edge of the heads 13.
- the depression 15 of the heads 13 is filled with an adhesive 17.
- an adhesive 17 This can be applied by brushing or knife coating, in order to effect an additional binding after the hooking operation has been carried out with the back 5 of the carpet in question.
- Suitable adhesives are, for example, acrylate-based adhesives, for example 2-ethylhexyl acrylate or butyl acrylate, preferably in different mixing ratios, in order to vary the plasticization, plasticity and adhesive strength as desired and as required.
- the adhesive fasteners 7 can be provided in the form of long strips or tapes when laying carpets from wall to wall. When laying the carpet in tile form, shorter strip sections which are suitably adapted to the individual tiles can be provided.
