Description

The present invention relates to a spacer, which

  preferably, is arranged on the back of a floor or wall covering. This spacer serves mainly to receive electrical cables and to guide them, correspondingly to the data

  space under the pavement in the intended direction.

  The object of the invention is to provide a spacer with which the laying of cables between the ground or the wall and a wall or floor plate having a visible edge is simple and can be carried out in series. in an economical way. This object is achieved, according to the invention, in that the spacer is flat and has, at least on one of its planar sides, projections, in particular in the form of buttons, leaving between them

  intermediate spaces to form cable passages.

  According to an advantageous embodiment, the spacer is formed of a plurality of individual bodies, in particular with symmetry of revolution, closed on one side or open forming said projections. Between said bodies are formed channels, which serve to guide the electric cables. A particularly economical and simple embodiment as regards the assembly consists in that said bodies are formed by connected hollow cylinders

  to each other by radial ties.

  The spacer according to the invention has the advantage that it can be made in one piece, in the form of an injection-molded body, in particular a synthetic material, such as PVC, polyurethane or polyamide. , polypropylene or ebonite. It is advantageous to use recovered polypropylene, which in this way is subjected to recycling to thereby contribute to the protection of the environment. The availability 1 of recovered polypropylene waste far exceeds the needs. To oppose an electrostatic charge, it may be advantageous to use, as a raw material for injection molding, a flame-retardant polypropylene, in which a proportion by weight of 5 to 25%

special smoke is mixed.

  According to another preferred embodiment, on the underside of the base layer (flexible) of a slab or strip of carpet, slab or strip of PZV or the like, as a floor covering, can be fixed a dsal plate 1.0 mm to 6.0 mm thick, made of alumrinium or any suitable metal, hard PVC foam or any suitable hard foam, or hard fiber plating or ana.ogue. The part

  The upper floor is thus formed according to the floor plan.

  the invention is laid, removably, on the baseplate fixed (glued or screwed) with buttons facing up on the floor. Moreover, on the lower 2- side of the hard backing plate, projecting elements with a spacing of 30.0 to 50.0 cm can be protruded, so that they are used for fastening. mutual friction in the interspaces of the buttons of the base plate. The shape of the weft elements is derived from the shape of the interspaces between the buttons of the base plate, while the size of the individual weft elements is chosen so that they are in contact with at least six buttons

  when mounted in the base plate.

  According to another preferred embodiment, the hard backing plate is provided, in place of the weft elements, on the underside of a layer of foam rubber / thin cellular product or a layer of flexible material that can adhere, in which the buttons of the plate

  1 base can easily sink for their fixation.

  In another embodiment, a modified polypropylene or a recovered polypropylene is used to improve the

  electrical conductivity of the button base plate.

  According to another embodiment in polypropylene injection molding, the buttons of the base plate have only a very small conicity related to the production technique (which can only be determined by measurement), so that the buttons appear cylindrical with a round base surface, or parallelepipedic or cubic with a quadratic basic surface. For such a shape of the buttons, there is a higher load capacity than for a conical shape and, for the same useful width of the channels formed by the buttons, a smaller space

  buttons relative to each other at the upper edges

  of them. This further results in an increase in the load capacity of the flooring according to the invention. According to another preferred embodiment, recesses are arranged between the buttons for the base plate, to save weight, raw material and material costs. The recesses may have a

  round, quadratic or other suitable form.

  According to a preferred embodiment in polypropylene injection molding, the buttons are open at the top, to save weight, raw material and material costs. According to another preferred embodiment of the base plate with polypropylene buttons, which can be used preferably as a wall covering, the buttons have, on their upper front side, an opening, which is smaller than the internal diameter of the buttons. , so as to form an inwardly directed edge. The openings may have a round, quadratic or other suitable shape. In the openings, it is possible to insert (glue) elements, to the outward projecting part of which hooks, rings or the like may be arranged for the installation of tools, materials, etc. in workshops. for fixing objects to be displayed (in exhibition stands, in shops and exhibition halls and the like). A particular advantage is that the (fixing) elements can be arranged individually and of course. depending on the particular case of use, without

  additional cost and duration.

  According to another embodiment. button base plate, holes for scn screws: provided in the base plate, to facilitate additional fixation to

using screws.

  According to another embodiment of the invention, the conical knobs are made so that the side walls are reinforced towards the plate of polypropylene.

  base, to obtain a higher load capacity.

  In another embodiment for particularly high load capacities, as may be required in factories, workshops or the like, the button base plate may be made from sheet steel or other appropriate metal supports by a cold-forming process or other

appropriate.

  According to another preferred embodiment, the buttons have a quadratic opening, the inwardly extending walls of which form a right angle of 900 with respect to the base plate. On the upper front side of the buttons, the opening is made so

  it creates a setback oriented inward.

  The opening is intended for receiving plug-in elements, which are made so that they are completely inserted into the buttons and are flush with the top edge of the buttons. The upper faceplate of the plug-in elements further rests on the recess facing inwards and is held fixedly there. The plug-in elements are provided with a cross slot, which allows a hold against the inner wall of the buttons, and they are provided with more than one hole for a screw. By installing the holding devices already described in a general manner or the like on the plug-in elements by means of a screw, the four wings formed by the cross slot are spread apart and press the plug-in element more firmly.

in the buttons.

  According to an advantageous embodiment of the button base plate, the opening already described generally has an octagonal shape, which, because of the contact surfaces more

  with plug-in elements, facilitates the installation of

  removal and removal of these elements. At the same time, the octagonal shape of the openings reduces the need for raw material and material costs compared to the quadratic openings described above. The base plate is at the same time made so that it projects on two sides arranged with respect to each other at right angles, so that it also serves as a spacer with respect to the plate adjacent when laying plates on walls or on the floor. The outer edge of the protruding parts is curved concavely according to the radius of the buttons and receives, in these curvatures, the buttons of the adjacent plate, so that, in addition to the spacing

  1 correct buttons relative to each other,

  at the same time is guaranteed during installation.

  The top faceplate of the plug-in elements is provided, in a particular embodiment, with a sticky tape on both sides, for fixing the ground element which rests thereon, such as carpet slabs, PVC slabs or the like. , or, when the button plate is used as a wall covering, to fix wall cladding or the like.

industrial products.

  It is also advantageous to choose a type of material

  raw material such as flame retardant polypropylene.

  it is furthermore advantageous to make the button plate electrically conductive by correspondingly modifying the raw material, for example by using (mixing) special carbon black to eliminate static charges and to improve the resistances. surface and interior. The proportion by weight of the substance

  conductive can be between 5 and 25%.

  The base plate 25 is preferably formed with holes for screws 27, in order to fix it in addition to or instead of the usual fixing on the floor or wall surfaces (without additional preparatory work such as the

  subsequent drilling of screw holes).

  In general, like parts are designated by the same reference numbers as in the previous figures. FIG. 4 shows a modified embodiment, in which a base plate 28 has round recesses 29 between

open buttons 30.

  Figure 5 shows a slightly modified embodiment of a base plate, in which the buttons 30 are formed by hollow cylinders connected to each other in the manner of a grid by radial cross members 32 '.

  Figure 16 is a top view and Figure 17 is a cross-section of another button plate 25, which may be used both as a floor plate and as a wall plate. The buttons 45 have a conical shape with an inclination angle of the lateral surfaces with respect to the base plate 25, which is between 600 and 890. The quadratic opening 46 on the front face of the buttons 45 forms an annular shoulder internal 47 from 1 to 2 mmr wide and 1

at 2 mm deep.

  The internal surfaces of the openings 46 are arranged at an angle of 900 relative to the base plate 25. The openings 4E serve to receive plug-in elements 4z, which can be pressed fully into the buttons, so that the front plate 49 of FIG. the plug-in element 48 rests on the internal recess and is a flower of the upper end face of the bumps 45 (see

also Figure 17).

  The plug-in elements 48 have, at their lower part, a cross slot 5O0 (FIG. 18) which fixes the plug-in elements 48 with slight pressure in the bzutohs 45. The plug-in elements are additionally provided with a screw hole. 27, which (as already described) serves for the installation of rings, hooks, containers and the like. The plug-in element thus formed is also advantageous for fixing plugs or protective plates, plug-in sockets and the like in places where the

  cables laid under the flooring must be completed.

  The plug-in elements allow the screwing of protective sockets, plug-in sockets and the like without additional mounting, such as holes, dowels and the like. In another embodiment, the faceplate 49 of the plug-in member 48 is provided with a sticky tape on both sides, to fix slabs that rest thereon or, when using the button plate as a wall covering , attach additional wall cladding or the like. Figures 20, 21,22 and 23 show finally another preferred embodiment of the button plate 25, wherein the buttons 55 have at their inner periphery an octagonal opening 54. The opening receives plug elements 48, which The shaft is split and each has a cross slot 50 and a screw hole 51. In the plugged state, the plug-in elements 48 are flush with their front plate 49 of the front surface of the buttons 55. The octagonal shape of the openings facilitates the introduction and removal of the plug-in elements 48, as the resistance is low because of the small contact area between the buttons and the plugs.

plug-in elements.

  As appears in particular in FIG. 20, the rectangular button plate has on two neighboring longitudinal sides projections of the same length 56, the length of which corresponds to the mutual spacing of the

  buttons. These protrusions may be engaged, in correspondence

  form, by their front edge with, each time, a protrusion 55 of a neighboring button plate. In the case shown, the projections are concavely curved and receive, in these concave recesses, the corresponding convex shape projections of neighboring plates. Thanks to this, a correct installation of the button plates on the floor and on the wall is ensured, without it being necessary to use additional auxiliary means, such as

  laying jigs or spacer models or the like.

  As can be seen, in the case of the button plates described, each of these is a series of economically feasible plates which can be laid under the floor mat or a covering. wall, may consist of a colored imperfect material. For this reason, the material to be used can be

  a material for recovery or recycling.
