Definitions

  • the invention relates to a worktop unit according to the preamble of claim 1.
  • a worktop is a composite panel consisting of a core panel and a corner panel.
  • the core plate is mostly a chipboard, but it can also be plywood, natural wood or other materials.
  • the check plate which is glued to the top of the core plate, is usually a high-pressure laminate (HPL) plate, although other materials are also known here.
  • HPL high-pressure laminate
  • the cover plate is often bent around the rounded edge of the core plate in a post-forming process and guided down to the underside of the core plate, possibly even covering the entire surface.
  • the composite panels forming the previously described worktops are usually manufactured with a length of several meters and then cut to the length appropriate for the respective application.
  • the width of composite panels is specified, although there are many options.
  • the working depth for worktops is standardized; in the kitchen area, for example, a standard depth of 600 mm is specified for the working area. Thereafter, the manufacturers of composite panels were directed, so that considerable manufacturing capacity is focused on the production of composite panels with certain widths.
  • a greater depth than the standard depth of z. B. 600 mm ge wishes.
  • This wish is taken into account in the known worktop unit from which the invention is based (DUROpal brochure "High-pressure qualities.
  • the range of services from DUORpal" P 69 15982 in that a widening plate is connected to a worktop in an offset plane.
  • the widening plate is located at a distance above the worktop and between the widening plate and the worktop a support and connecting bar running perpendicular to the plane of the worktop and the widening plate is provided as the connecting profile.
  • the support and connecting bar is connected to the top of the worktop with the aid of fastening screws and has an upwardly open groove on its edge facing the widening plate.
  • the widening plate itself is provided on the underside at a certain distance from the front longitudinal edge with a groove running parallel to the longitudinal edge.
  • a double bar can be inserted into the groove of the support and connecting bar on the one hand, and inserted into the groove of the widening plate by clamping.
  • the widening plate is detachably connected to the connecting profile formed by the support and connecting bar.
  • the known worktop unit is structurally very complex, and not only because of the need for an additional support and connection provide bar, but also because of the need to connect the support and connecting bar on the one hand with the worktop, on the other hand with the widening plate as moisture-proof as possible. It has proven to be particularly problematic that the top of the worktop, that is to say the area which is in itself perfectly protected against moisture by the cover plate, must be damaged at the fastening points of the connecting profile. These connection points, mostly in the form of wood screws, are particularly sensitive to moisture with their arrangement on the top of the worktop. In the known worktop unit, you practically cannot do without a permanently elastic sealing material - silicone strips.
  • connection profile must have a minimum distance from the back of the worktop.
  • the invention is based on the object of optimizing the worktop unit of worktop and widening plate, wall cover strip or panel plate explained at the outset in connection technology and in particular with regard to the moisture seal in the connection area.
  • the object presented above is achieved in a worktop unit with the features of the preamble of claim 1 by the features of the characterizing part of claim 1.
  • the formation of a step-like raised rear working area does not in itself require a support and connecting bar.
  • the thickness of a widening plate designed as a composite plate leads to a step-like height shift of several centimeters.
  • the complex connecting profile known from the prior art has now been converted into an extrudable connecting profile which is approximately Z-shaped in cross section.
  • This simple shape of the connecting profile makes it possible to attach it to the back of the worktop with its fastening flange, that is to say to leave the top of the worktop, which is optimally protected from moisture by the cover plate, completely unaffected.
  • the Z-shape of the connecting profile ensures that the strip for connection to the widening plate, the wall cover strip or the panel plate is offset from the fastening flange.
  • connection profile can be optimally sealed in the area of the mounting flange from the worktop, since the rear of the worktop cannot be seen. Sealing measures can therefore be provided here solely from the point of view of sealing technology, without having to take optical aspects into account.
  • Sealing measures can therefore be provided here solely from the point of view of sealing technology, without having to take optical aspects into account.
  • the seal on the top of the worktop it is important that an undamaged cover plate is available, which offers optimal conditions for a flat, moisture-tight seal.
  • the worktop unit shown in FIG. 1 initially has a worktop 1 designed as a composite panel, preferably as a composite panel with a standard width of 600 mm.
  • a widening plate 3 is attached to a longitudinal edge, usually the rear longitudinal edge 2 of the worktop 1. As the other figures show, it does not matter whether this is a widening plate 3, a wall cover strip or a panel plate. These further plates to be attached are each designated with the reference symbol 3.
  • the widening plate 3 is also designed as a composite plate.
  • a connecting profile 4 is provided between the worktop and the widening plate 3.
  • each composite panel consists of a core panel and at least one cover panel, preferably an HPL panel. This has already been explained at the beginning of the general part of the description.
  • Fig. 1 clearly shows that the widening plate 3 on the underside 5 at a certain distance from the front longitudinal edge 6 has a groove 7 running parallel to this longitudinal edge 6.
  • the connecting profile 4 is on the one hand firmly connected to the worktop 1 and on the other hand detachably connected to the widening plate 3.
  • the connecting profile 4 has a strip 8 (tongue and groove connection) which engages in the groove 7.
  • a plurality of strip sections distributed over the length of the connecting profile 4 could also be provided. From the point of view of fastening technology, the connecting profile 4 could also be provided overall in the form of profile sections.
  • FIG. 1 In the exemplary embodiment shown in FIG. 1, but not necessarily present, there is a plastic or rubber sealing profile 9 sealingly resting on the top of the worktop 1.
  • the sealing profiles 9, 11 consist of permanently elastic material, in particular of silicone, wherein the sealing profile 9 can also consist of another plastic material or rubber material.
  • FIG. 4 is expediently used in addition to the figures mentioned in each case, which shows, in sections, the area of the connecting profile 4 particularly large and clearly.
  • the connecting profile 4 is approximately Z-shaped in cross-section with the bar 8
  • one of the bar 8 is substantially perpendicular protruding cross bar 12 and a from the cross bar 12 opposite to the bar 8 substantially vertically projecting mounting flange 13 and is attached via the mounting flange 13 to the longitudinal edge 2 adjacent back 14 of the worktop 1 and that the widening plate 3 or the like with the underside 5 rests directly on the top of the worktop 1.
  • the Z-shape of the connecting profile 4 can be seen particularly clearly from FIGS. 1 and 4.
  • the widening plate 3 is designed as a composite plate with a core plate and HPL cover plate, which is indicated in the drawing without reference numerals being used.
  • the essentially vertical front 15 of the widening plate 3 is thus provided with an HPL surface, so that this front 15, like the top of the widening plate 3, is extremely heat-resistant.
  • the strip 8 is designed as an approximately V-shaped spreading profile, preferably provided with barbed longitudinal ribs 16. This ensures, in particular when using a plastic extruded connecting profile 4, that the clamping forces of the strip 8 in the groove 7 are sufficient to ensure a secure but detachable connection. 4 makes it clear that the tip of the bar 8, which is designed as an expansion profile, facing the groove 7 is beveled in a trapezoidal manner, in order to ensure easy insertion of the bar 8 into the groove 7.
  • the distance of the groove 7 from the front longitudinal edge 6 of the widening plate 3 or the like is expediently 5 to 25 mm, preferably about 10 mm. In the present exemplary embodiment, the distance is approximately 10 mm from the longitudinal edge 6 to the edge of the groove 7 facing the longitudinal edge 6.
  • the Z-shape of the connecting profile 4 allows the realization of two different relative positions of worktop 1 and widening plate 3 or wall edging strip or panel plate, simply by the possibility of fastening the connecting profile 4 to the worktop 1 in a reversed arrangement.
  • the width of the crosspiece 12 of the connecting profile 4 is important for the offset between the two arrangement options. This width can of course be largely dimensioned arbitrarily, the strength of the material used for the connecting profile 4 must be taken into account.
  • the crosspiece 12 has an effective width between 5 and 10 mm, here exactly 7.5 mm. This is the distance between the center planes of the strip 8 and the mounting flange 13. This dimension results in the illustrated embodiment between FIGS. 2 and 3 an offset of 15 mm.
  • the width of the work area available on the worktop 1 is consequently reduced by only 5 mm; in contrast, in the exemplary embodiment of FIG. 3, the width is reduced by a total of 20 mm.
  • the connecting profile 4 should consist of an extrudable plastic, which is preferably PVC.
  • connection profile For the attachment of the connection profile on the worktop, the same connection technology as between the connection profile and the widening plate is also possible.
  • the connecting profile has a bar which projects essentially vertically from the fastening flange and that a corresponding groove is provided on the rear of the worktop.
  • Another fastening alternative is to glue the fastening flange to the back of the worktop.
  • a pure gluing of the fastening flange of the connecting profile to the back of the worktop without further fastening measures is often not without problems with regard to the exact positioning of the connecting profile.
  • a pure glue connection is not always optimal for the shear stresses that occur. Nevertheless, a glue connection naturally has handling and sealing advantages.
  • the top of the worktop is formed from the top around the back of the core plate to the bottom.
  • optimal moisture protection of the back of the worktop can be guaranteed without the basically rectangular arrangement of the top and back of the worktop Worktop.
  • connection profile is then finally completed on the side assigned to the worktop to form a U-shaped bracket profile, so that it can be clamped onto the worktop without further notice.
  • the web covering the worktop on the underside can be formed on both sides.
  • a further connection technology in particular an adhesive connection, only needs to ensure that the connection profile does not slip off the worktop.
  • the fastening flange 13 of the connecting profile 4 is screwed or nailed to the rear 14 of the worktop 1.
  • the fastening flange 13 of the connecting profile 4 be concave, preferably biconcave, on the side coming into contact with the rear side 14 of the worktop 1.
  • a biconcave design takes into account the reversible construction of the connecting profile 4. This cannot be seen particularly clearly in the figures for reasons of drawing. In any case, it is essential that particularly high pressure and thus sealing forces occur at the edges of the mounting flange 13 in this design.
  • a plastic sealing bead in particular a polyurethane sealing bead
  • a diameter of the sealing bead of 0.75 mm should already be sufficient here.
  • Fig. 4 shows with particular clarity that the sealing profile 9 here has a special cross-sectional shape in accordance with a preferred teaching of the invention.
  • the sealing profile 9 assigned to the upper side of the worktop 1 is of approximately L-shaped cross section and has an L-leg 17 between the widening plate 3 or the like and the worktop 1 and the other L-leg 18 engages in the groove 7 and that the width of the groove 7 is matched to the added width of the strip 8 and L-leg 18.
  • the thickness adjustment of the sealing profile 9 and crosspiece 12 of the connecting profile 4 mentioned in the preceding section thus primarily relates to the one L-leg 17 between the widening plate 3 and the worktop 1. Otherwise, FIG.
  • the overall L-shaped sealing profile 9 creates an extremely long sealing joint which has a vertically rising area in the groove 7.
  • the widening plate 3 is therefore optimally protected against moisture.
  • a silicone strip can also be introduced under the sealing profile 9, in particular if the connecting profile 4 is slightly lower than the top of the worktop 1, as has been explained in detail above.
  • the sealing profile 9 has on the free longitudinal edge of the one L-leg 17 a sealing lip 19, preferably projecting on both sides.
  • the sealing profile 9 is made of PVC, in particular hard PVC or hard PVC soft
  • the sealing lip 19 is made of PVC soft according to preferred teaching.
  • An optimal seal is achieved via the sealing lip 19, in particular in the case of a version made of PVC soft, both towards the front 15 of the widening plate 3 and towards the top of the worktop 1. It goes without saying that the sealing lip 19 is designed so far that it is under tension. This can be clearly seen in the figures.
  • the sealing effect of the sealing profile 9 on the upper side of the worktop 1 is largely determined by the surface roughness or surface structure of the worktop 1. This in turn depends on the decor chosen.
  • the surface of the cover plate is smooth regardless of the decor of the cover plate.
  • the surface structure of the worktop cover plate (or the cover plate of the widening plate, the wall cover strip or the panel plate) is consciously modified in an area that is no longer visible or practically no longer visible in the installed state in order to achieve optimum moisture sealing. This is easily possible when the worktop is initially manufactured and leads to excellent results.
  • the sealing profile 11 on the rear side 10 of the widening plate 3 is a seal made of permanently elastic material, in particular a silicone strip. Often such a silicone strip is actually not attached during installation, ie the widening plate 3 or the like is not sealed off from a wall.
  • a further teaching of the invention is that the sealing profile 9 assigned to the top of the worktop 1 and the sealing profile 11 or the like assigned to the back 10 of the widening plate 3 or the like have an identical cross section. Without additional production engineering effort, namely simply by adding twice and possibly attaching the sealing profile 9, 11, an optimal sealing solution is found here. The requirement for sealing with the sealing profile 11 is present, but there is no need to provide a further, costly individual part.
  • the rear 10 of the widening plate 3 or the like applies at a distance from the longitudinal edge which is matched to the width of the transverse web 12 of the connecting profile 4 and is parallel to the longitudinal edge extending groove 20 is provided and that the groove 20 has a width matched to the width of the other L-leg 18 of the sealing profile 11.
  • FIGS. 1 and 4 FIGS. 1 and 4, FIG. 1 for a widening plate 3, and FIG. 4 for a wall cover strip 3.
  • FIG. 1 shows this and the possibility associated therewith to compensate for changes in width of the widened plate 3 or the like which is planed in.
  • Fig. 1 shows that the widening plate 3 provided here is supported on the rear longitudinal edge on a support bar 21 nailed to the wall.
  • the widening plate 3 lies here by its own weight. That is enough for frequent applications.
  • the connecting profile 4 realized according to the invention now offers the possibility of providing the attachment to the rear longitudinal edge in the same way as to the front longitudinal edge of the widening plate 3. In this respect, it is then true, without this being shown, that the widening plate on the underside, at a certain distance from the rear longitudinal edge, has a groove which runs parallel to this longitudinal edge and is matched in width to the width of the strip of the connecting profile.
  • FIG. 5 shows the teaching of the invention applied to a panel plate 3 on a worktop 1.
  • a panel plate 3 often has a thickness of approximately 16 mm. Given the dimensions given in the present exemplary embodiment, this is not sufficient to completely introduce the groove 7 into the lower edge.
  • the groove 7 is embodied here as an angular groove which is open towards the rear of the panel plate 3 and is completed by a reinforcing plate 22, for example made of plywood or the like, which is connected to the panel plate 3 by fastening screws. Otherwise, the panel plate 3 is fastened by means of the connecting profile 4 to the rear side 14 of the worktop 1 in exactly the same way as in the previously explained exemplary embodiments.
