Definitions

  • Resin-soaked papers are fed to a press together with the backing plate in the manufacture of laminate panels. Under the supply of heat and pressure, the papers are glued to the carrier plate.
  • the decorative paper already has the layer with the abrasion-resistant particles.
  • cord or rod-like elements Between the panels.
  • the cord or rod-like elements consist wholly or partly of compressible material.
  • the cord or rod-like elements are able to compensate for shrinkage and expansion phenomena, so that gaps in the joints can be avoided.
  • connections for electricity, etc. distributed over a room are permanently installed. Either there are already fixed cable feeds in the ground. Alternatively or additionally, cables are brought over the ceiling coming from above to the desired location.
  • connection in the floor is excellent and can hardly be changed in retrospect. If cables are brought over the ceiling, in particular the appearance is adversely affected. Also, the effort is still relatively large here. Laying is always to be carried out by a specialist, especially since a stable attachment to the ceiling is necessary.
  • the document EP 1 308 577 A2 discloses a floor system with a plurality of panels. Known panels thereof may be carriers of a lighting element, which are connected by means of a mounting frame with the corresponding panel.
  • the document EP 1 308 577 A2 has been republished and is therefore to be considered only in the assessment of novelty.
  • the object of the invention is to provide a kit of the type mentioned, which can be handled flexibly, so for example allows a flexible supply of cable or hose feeds.
  • kit for a covering with the features of claim 1, it is possible to integrate a supply of cables or hoses in the panels. Since the panels can be laid on a screed or the like at any time and also easily removed again, a flexible installation, for example, along the hollow body is possible. Rod-like or cord-like elements can serve directly as a current conductor or be designed hose-shaped. A power supply in the middle of a room is possible without problems. An elaborate ceiling construction or early planning for a fixed installation is not required.
  • the components comprise panels, which are formed from a base body with at least one passage for the passage of cables or hoses and a cover.
  • the lid can in particular be positively connected to the main body. Below the cover then a cable or hose can be laid. Laying is particularly easy, because only laid and then still a lid must be attached.
  • the attachment of the lid can be done inter alia by gluing.
  • the lid is fastened in a form-fitting manner. This type of attachment
  • it is particularly easy to handle.
  • it is in principle possible to solve the cover in a simple way again. For example, at a later date another cable can be easily laid or an existing one replaced.
  • the main body for the passage of cables or hoses Can be connected to other panels. Seen from the common surface and / or the common underside, there are preferably elongated one or more recesses for the passage of cables or hoses in the main body.
  • a cable duct can be provided as a precaution in the covering.
  • the covering is formed by conventional panels, as known from the prior art.
  • the connection between the panels and / or between the panels and the base body takes place in particular by means of tongue and groove connections with further locking means as are known, for example, from EP 1 024 234 B1.
  • the bonding can then be done without glue.
  • a subsequent release of the panels is then possible in principle.
  • An already laid cable channel can then be subsequently changed by disassembly of the covering and relocation.
  • a cable duct can be easily installed later at the desired location.
  • the main body is provided with a lid. With the lid, the recess is closed in the body.
  • the recess serves for the passage of cables or hoses.
  • the main body with the lid represents a panel in the context of the invention.
  • the lid for closing a recess which is provided for the passage of cables or hoses, advantageously has on the underside latching means by which the lid can be positively secured to at least one component, in particular to the abovementioned body in a form-fitting manner.
  • the locking means consist in an easy-to-manufacture embodiment of substantially vertically downwardly leading flanks.
  • at the end of the respective flank there is at least one laterally projecting locking element.
  • the flanks are suitably designed elastically. The locking element passes through the latching so behind a projection in the associated component, that thereby the positive locking is effected.
  • the respective locking element engages around the respective projection such that the lid can not be released from the component by a simple pulling movement.
  • the lid can be solved depending on the embodiment by parallel displacement relative to the component. This variant is to be preferred if the cable channel is to be protected against unauthorized access, for example in public areas or in front of children. Alternatively, the cable duct in public areas so on a component fastened, screwed so that, for example, a release can only be achieved by means of tools.
  • the aforementioned locking elements do not engage behind or behind the projections in such a way that disengagement by pulling the cover upwards away from the covering is no longer possible.
  • This variant is preferable when it comes to ease of use and special protection against unauthorized access is not required.
  • main body with recesses for the passage of cables or hoses wherein the main body can be connected to each other in particular via a tongue and groove connection so that the recesses provide a common channel or a common groove for the passage of cables or hoses. In this way it is possible to provide a channel of any length for the passage of cables or hoses.
  • the components are located in the recesses provided in particular cables for the management of electrical power.
  • the cables are or will then be properly connected to the plugs or sockets, thus providing a conventional connection for power.
  • Holes in the lid serve to lead hoses or cables at the desired location from the cable channel formed, for example, by the base body and cover at the desired location in the covering or lead out.
  • a cover has been placed on a base body, it advantageously forms a common planar surface with the base body.
  • a smooth finish is achieved so that no protrusions can make trip hazards.
  • the surface formed may be provided with slightly protruding nubs, for example, to prevent slipping on the surface.
  • the cable channel is then preferably laid along a step. In this way he fulfills a dual function. On the one hand, a person is particularly protected against slipping at the stage. The nubs also signal a special danger spots. On the other hand, it serves the cable or hose feedthrough.
  • the recess for the passage of cables or hoses in a base body extends from one end face to the opposite end face so as to be able to connect a plurality of recesses to form a continuous channel.
  • a recess in a body for the passage of cables or hoses is advantageously accessible from one side open, and especially from the lining surface ago. So can be placed in the recesses in a laid covering from the top comfortably a cable. The access to the recess is then limited in the surface preferably by protruding rounded nubs. Due to the rounding on the relevant surface, it expands slightly towards the outside. As a result, the placement of a lid and the associated closure of a recess is facilitated. Damage to edges is thereby avoided. If the lid also has nubs, the transition between the base body and the lid is advantageously virtually imperceptible.
  • the main body which has a recess for the passage of cables or hoses, preferably comprises projecting elevations, on which the associated lid, which is provided for closing the recess, rests in the closed state.
  • the lid is thus on relatively small areas. Small contact surfaces On the one hand, they can be manufactured relatively simply with precision so as to ensure a smooth covering surface. The risk of disturbing pollution z. B. in the form of dust is relatively small for small contact surfaces. Further, the surveys can also serve the subdivision of a recess in several areas, so that cables can be reliably separated spatially separated if necessary.
  • a recess is not closed by a cover, then the recess is advantageously accessible from the outside in the case of a laid covering, and expands altogether at the edge outwards.
  • a lid can be very easily put on. Alternatively, it is possible that the lid tapers downwardly to easily put it on.
  • the main body may be formed in one embodiment as a heating or cooling element or include heating or cooling elements. It thus serves to control the temperature in a room. Underfloor heating systems have the disadvantage of reacting too slowly. Furthermore, the control is difficult. By the main body directly represents a heating or cooling element, or heating elements, a much more direct contact is made to the room compared to conventional underfloor heating. The known problems with underfloor heating can be significantly reduced.
  • the base body and / or the lid made of metal, in particular aluminum.
  • Metal allows a stable production of filigree structures and is therefore to be preferred.
  • a basic body has a recess for the passage of cables or hoses, this is advantageously divided by a dividing wall into at least two areas. Several cables or hoses can then be installed spatially separated, which is often desirable for reasons of clarity and / or safety.
  • the coupling elements mentioned in the preceding paragraph allow the affected two components (panels and / or basic body) to be positively connected both perpendicular to the common surface and also parallel to the common surface and at the same time can be connected to each other perpendicular to the common joint. Laying is so easy and can even be done by laymen.
  • the aforementioned gap or recess occurs in particular on the surface of two panels, which forms the visible part of a floor or wall cladding. From the surface then the cord or rod-like element is visible. In the locked state, the cord or rod-like element is particularly dimensioned such that it completely fills the width of the gap. Advantageously, the cord or rod-like element is slightly wider. It is then in the compressed state within the gap.
  • panels connected integrally to the panel can be provided which consist of a wooden material and which can nevertheless be displaced relatively easily along a common connecting joint even when two panels are interlocked with one another. If the gap with the cord-like or rod-like element is located on the visible surface, then new design possibilities open up as a concomitant feature. In the joint area, for example, black rubber or silicone material becomes visible. The surface of the panel may otherwise have a strong contrast thereto.
  • the cord or rod-like element is color-matched to the visible surface.
  • the customer can freely choose the color of the border and also modify it later. So it is possible to vary the appearance of already laid panels with a relatively small effort, without having to remove the flooring.
  • the recess provided on the surface by two adjoining panels thus offers, in addition to the technical advantage of easier displaceability, the possibility of being able to easily modify optical impressions.
  • the cord or rod-like element can be subsequently pressed or inserted from the surface into the gap or the recess. However, it may also already be connected to a panel, in particular if the cord or rod-like element consists of a compressible material. Subsequent insertion of a separate cord or rod-like element in a gap, however, has the advantage that the panels can be moved particularly easily, as long as the cord or rod-like element is not yet inserted.
  • the cord or rod-like element typically has a diameter or a width of at least 0.5 mm, preferably of at least 1 mm, particularly preferably of at least 2 mm.
  • the width does not regularly exceed 10 mm, unless a larger width is desired for visual reasons.
  • the width is less than 5 mm, more preferably less than 3mm. In principle, however, smaller or larger widths or diameters may be provided, for example for optical reasons.
  • the cord or rod-like element is in the locked state between two surfaces which cause a lock.
  • these can be the areas that are called contact areas here.
  • the cord then consists in particular of an elastic material such as rubber or silicone.
  • the cord or rod-like element is then in particular partly in a depression and is pushed further into this or even completely when panels are locked together.
  • a panel is latched in a second by a rotary movement or a lowering movement, which is known for example from the document DE 20008708 U1.
  • the cord or rod-like element is pressed into the recess, Due to the presence of a game now one panel can be pushed further in the direction of the other panel. As a result, the depression is released again. The cord or rod-like element relaxes and thus passes between the two (contact) surfaces, which cause a lock.
  • the aforementioned recess is preferably immediately before the transition to the locking element, in this recess is the cord or rod-like element inserted or has already been attached to the factory here, so for example vulcanized.
  • a gap or a recess remains on the surface.
  • a second cord or rod-like element is then introduced.
  • a cord or rod-like element made of compressible material may already be attached to the surface at a joint edge of a panel. This can be advantageous to achieve the aforementioned design effects or to compensate for stresses that are practically unavoidable especially in a wood material.
  • the cord or rod-like element may for example be pressed into a corresponding depression. Subsequently, the panels are pushed towards each other. In a corresponding embodiment, in this successive slide a Pen pass into a groove and thus cause a locking perpendicular to the common surface.
  • the aforementioned cord or rod-like element finally relaxes and passes between the two locking contact surfaces.
  • the cord or bar-like element may have a circular or triangular-shaped diameter. However, if it is introduced from the surface last, it may be advantageous that the cord or rod-like element is designed hook-shaped on two opposite sides. If the cord or rod-like element is pressed into a gap from above, these hooks act like barbs. If the cord or rod-like element is pressed into the gap, then the visible surface of the cord or rod-like element can be made flat, so as to provide a surface finish with the remaining surface of the panels.
  • a curved recess for example, can be provided so that obliquely protruding hooks can be pressed better into the gap.
  • the cord or bar-like element advantageously comprises a thread that can not be stretched practically.
  • the thread is then always wrapped by a compressible material. This ensures that the cord or rod-like, consisting of a compressible material element is not disadvantageously stretched by the pressing in a gap or in a recess. If the cord or rod-like element initially stretched, it will contract again when laid. This undesirable areas would occur in the recesses or columns, which are not filled with a cord-like or rod-like element.
  • a connection is possible by a panel is first lowered perpendicular to the other.
  • the one panel is arranged parallel to the second.
  • the narrow sides are provided with such locking elements when the surface of a panel is rectangular.
  • the longitudinal sides are then preferably designed such that a connection usually requires a rotational movement about a connecting joint around. If a panel is connected on the longitudinal side by a rotational movement with the longitudinal side of a second panel, then a narrow side can at the same time reach the corresponding locking or coupling element of an already installed panel. It is also the narrow side of the already laid panel.
  • Moving further may be particularly undesirable if there is a small protrusion, for example because of a door frame, in a room to which a panel should possibly be closely adjacent. Then it is particularly advantageous to be able to connect panels by a lowering movement.
  • the narrow sides can be obtained, for example, in the manner known from the document DE 20008708 U1, as far as the coupling elements known therefrom relate to a connection by lowering.
  • the cord or bar-like element may have a substantially rectangular or square diameter in order to effect a surface finish on the surface.
  • a cord or rod-like element has the desired elasticity or flexibility when the width or the diameter can be reduced by compression. Solid metal or wood is not compressible.
  • the claimed dimensions of the panels are advantageous because they can be handled easily. In particular, dimensions below 100 cm are advantageous because then the panels can be easily transported even in the trunk of limousines.
  • rod-like or cord-like elements are provided, these are preferably such that the restoring forces that occur due to the rod-like or cord-like elements are such that no gap remains on the surface. It is therefore advantageous that a rod-like or cord-like element which adjoins the visible surface of the panels, can cause relatively low restoring forces. Panels are not pressed so much undesirable far.
  • the restoring forces can be suitably adjusted by selecting the materials that make up the rod or cord-like element. Additionally or alternatively, the cross sections can be suitably chosen.
  • the rod-like or string-like element adjacent to the surface therefore preferably has a larger area in cross-section than that of the other rod or cord-like element.
  • a cord or rod-shaped element causes a locking of two panels in one of said directions, that is, for example, perpendicular to the common surface of the panels.
  • two panels are locked together and at the same time perpendicular to the common joint with each other when the rod or cord-shaped element is pushed into a corresponding recess.
  • the cord or rod-shaped element in the simplest case has a rectangular cross-section.
  • the coupling elements of the two panels to be connected include recesses, which also have a rectangular cross-section. If the two panels joined together, so for example by moving in a plane, so finally an end position is present, in which the two aforementioned recesses border with the rectangular cross-sections.
  • connection in which a connection is made on the basis of a tongue and groove connection, an elastic lip or flank together with further locking elements are provided so as to allow a positive connection by moving in a plane, damage can occur in particular when the material is relatively rigid. This is particularly the case when the coupling elements consist of a wood material, such as HDF or MDF. These easily possible damage to the coupling elements can be avoided in the aforementioned embodiment.
  • the connection can be very stable mechanically, since vertical or undercut contact surfaces can be provided. Even with inclined contact surfaces, as these are known from document EP 00843763 B1, a more stable mechanical connection can be achieved be made possible because an elastic edge is not required and the locking element can protrude relatively far.
  • the rod or cord-like element has, for example, a constriction in cross section.
  • the rod or cord-like element In order to push the rod or cord-like element in recesses in coupling elements, so as to lock two panels together, the rod or cord-like element is preferred a smooth surface to keep sliding friction forces occurring during insertion low.
  • the rod-like or cord-like element then consists in particular of non-compressible or hardly compressible material in order to be able to avoid a gap on the surface of the panels even if no additional rod-like or cord-like element is to be introduced on the surface.
  • Teflon may therefore be appropriate.
  • HDF, MDF also have relatively smooth surfaces and therefore can also be used with preference.
  • a rod made of metal or with a metallic surface has a smooth surface and can therefore preferably be used.
  • the rod or cord-like element tapers advantageous at least one end.
  • the embodiment in which the insertion of a rod-shaped or cord-shaped element brings about a locking of two panels is provided on narrow sides of panels which have a rectangular surface. Panels are then joined together on the longitudinal sides, in particular by a rotary movement. If necessary, narrow sides of already laid panels are then pushed towards each other. Finally, the rod or string-like element is pushed in on the corresponding narrow side. Narrow sides, between which the rod or cord-shaped element is pushed in for the purpose of locking, are to be preferred, since here the distance is comparatively short. Accordingly short, the rod or cord-shaped element is to push in to lock two panels accordingly.

  • a method for laying the covering elements or panels comprises the following steps.
  • a first panel has already been laid. It has laterally lower projecting flanks. In the above edge is a groove-shaped recess. Either in this recess or in a recess within the recess, a cord (or rod), the radially elastic can be deformed, inserted.
  • the cord or rod preferably consists of a tendon of a material with low elastic properties, which is enveloped by an elastic material such as rubber. Due to the tendon, the cord (rod) does not change its length.
  • a second panel is connected with one side, and preferably its longitudinal side to the first example, obliquely connected by pivoting in the common panel plane with the already laid panel so that they are connected to each other parallel to the common surface and perpendicular to the common joint by positive engagement , Depending on the embodiment, the connection can also be done by lowering one panel over the other.

  • a spring of a panel enters the groove of another panel.
  • the two panels are thus also connected to each other vertically to the floor level. If necessary, the two last laid panels are pushed in the direction of the already laid panel, whereby a classic tongue and groove connection is brought about. Due to the classic tongue and groove connection, the two panels are locked vertically to the smoother surface by positive locking.

  • the dimensions of the cross-section of the channel 42 are adapted to the cord-shaped element 18 so that it will not twist within the channel 42.
  • due to the adaptation it is practically impossible to insert the cord-shaped element 18 through 90 ° into the channel 42.
  • the tool 40 is used as a laying aid for laying the panels 1, 2, 2a. With the assistance of the laying aid, the cord-like element 18 is brought into the joint 11, which is formed by the panels 1 and 2.

  • the width of the spring 46 is initially outwardly and in particular down or forward dimensioned so that it can be inserted into the gap of the joint 11, which remains at the surfaces of two joined panels 1, 2 at least. If, for example, the spring 46 tapers sufficiently downwards, the spring 46 can be brought into the aforementioned gap 11 coming from above by lowering it. If the spring 46 tapers towards the front, this taper 47, 49 can be introduced into the gap 11 and thus the spring 46 can be brought between the panels 1, 2.
  • the wider portion 48 of the spring 46 is sized so that the two panels 1 and 2 are pressed apart when the spring 46 is further inserted between the panels 1 and 2 and thus the wider area 48 passes suitably between the panels 1 and 2.

  • the laying aid or the tool 40 is provided in one embodiment with rollers 51 and 52 in order to easily move the tool 40 along the connecting joint 11 with the aid of the rollers 51, 52. Otherwise, the tool 40 slides over the panels 1 and 2. There is a risk that the surface of the panels 1 and 2 may be damaged.

  • the dimensions are preferably dimensioned to leave a small clearance between the cord-like element 18 and the pressed-apart panels 1 and 2 to facilitate insertion of the cord-like element 18 into the connection joint 11.
  • the cord-like element 18 thus usually arrives from above into the connecting joint 11.
  • the connecting joint 11 behind the laying aid 40 closes again slightly due to the pressure which has been caused by the first, compressed, cord-like element 22. If the connecting joint 11 has closed again somewhat, then the cord-like element 18 is held in place by means of a suitably provided dimensioning and / or shape by positive locking and / or frictional engagement between two panels 1 and 2.
  • the tool 40 has at the rear end near the end wall 45 in an advantageous embodiment, a roller 51 which rolls above the connecting joint. This ensures that a smooth transition between the panels 1 and 2 and the cord-like element 18 on the surface is achieved. This case is not shown in FIGS. 15 a and 15 b.
  • the laying aid 40 is moved until a first transverse joint 60 is reached, as can be seen from FIG. 16, which shows a plan view of panels 1, 2, 2a. Behind the laying aid 40 a cord-like element 18 is then already got into the joint 11.

  • the eccentric member 70 may be bent at the end of the lever 73 so that this bent end 74 can be inserted into the lateral groove of one of the two panels 2 or 2a. Thus, the 90 ° rotated position of the eccentric member 70 is held. Otherwise, otherwise ensure that the eccentric member 70 is held in the rotated position.
  • the transverse side 60 is in particular a narrow side if the panels 1, 2, 2a have a rectangular surface.
  • the eccentric 70 is rotated back to the starting position.

  • the fixation may have been achieved by positive engagement and / or frictional engagement. According to Figure 17, the fixation is achieved in particular due to positive engagement, but also due to adhesion, since then the cord-like element 18 is slightly pressed with the preferred elongated cross-section in the joint.
  • the eccentric 70 is then pulled out of the channel 71 or a corresponding gap.
  • the laying aid 40 is moved on until the next transverse joint is reached.

  • the laying aid 40 laterally has a recess.
  • the laying aid 40 is moved during the laying so that the recess is aligned with a joint, the transverse side of a 60, in particular a narrow side comes from.

  • the spring 46 below the laying aid is such that it tapers over its entire length downwards so that the spring can be used coming from above into the joint. This is particularly advantageous when walls limit the lateral access to a joint.
  • a taper or step-shaped narrowing 76 downwards.
  • the tool 40 with the underlying spring 46 is then matched to this gap with the constriction 76, that the pressing apart of the two panels 1 and 2 is achieved only due to a pressure in the lower region, ie in the region of the constriction 76 and Rejuvenation is exercised.
