Definitions

  • the invention relates to a door leaf for a front door comprising a door frame made of hollow plastic profiles, wherein the visible surfaces of the hollow plastic profiles on at least one of the two door sides are covered with a cover plate, preferably with a cover plate that forms the entire visible surface of the door leaf.
  • the invention also relates to a hollow plastic profile for forming a door frame and a method for subsequently producing a door leaf from an existing door leaf.
  • a door frame is first formed from hollow plastic profiles. Insulating material can preferably be arranged between the hollow plastic profiles, in particular in relation to their thickness in the direction between the inside and outside of the door leaf. It is known for such door leaves to connect at least one of the cover plates, e.g. only the outer cover plate facing the outside, to the hollow plastic profiles, in particular also to an insulating material between the profiles, in a shear-resistant manner, e.g. by screwing or gluing.
  • the cover plate can also be attached or at least one cover plate can be provided which is only attached to the insulation material and is preferably arranged between the plastic hollow profiles like the insulation material.
  • the visible surfaces of the plastic hollow profiles not covered by the cover plate on such a side can be covered by facings which are visually identical to the cover plate.
  • the visible surfaces of the plastic hollow profiles are the surface areas that are parallel to the cover plate plane or door leaf plane. These surface areas of the plastic hollow profiles therefore face outwards towards the environment or inwards to the room. The visible surfaces are therefore part of the outer and/or inner profile walls of the respective hollow plastic profile.
  • the tensions in the door are usually also transferred to the adjacent areas, which are also undesirable there and can lead, among other things, to leaks due to the then inadequate installation of seals.
  • Plastic is more likely to twist, meaning that permanent distortion is possible due to the soft material. This results in the disadvantage of deformation of PVC profiles due to thermal expansion, caused by internal stresses as a result of different temperature effects, which must be eliminated/counteracted.
  • the utility model DE 203 14 017 U1 proposes a filling panel which is provided on one side with a layer arranged between the cover layer and the core,
  • the filling plate of a front door is designed in such a way that the warping of the filling plate caused by temperature differences is significantly reduced.
  • the compensation layer has a stabilizing effect on the filling plate, as it only absorbs tensions or forces when the filling plate warps due to temperature differences.
  • the filling plate of the type described here cannot, however, prevent thermal influences between the cover plate and the door frame profiles, or these problems do not occur here. Thermally induced movement of a cover layer relative to a filling made of insulating material still appears to be less critical than thermally induced movement relative to the door frame profiles, as insulating materials already have a degree of flexibility in themselves.
  • the invention is therefore based on the object of improving a door leaf of the type mentioned at the beginning and plastic hollow profiles to be used for it in such a way that the deformations and resulting stresses that occur on the front door due to the different temperature influences are at least reduced, preferably eliminated.
  • a thermally induced influence of a large-area cover plate of a door leaf on the frame construction of the door leaf should be reduced or preferably avoided.
  • a plastic hollow profile for the door frame construction of a door leaf in which at least one fastening recess is arranged in the visible surface to be covered by a cover plate of the door leaf, in particular in the wall of the plastic hollow profile that encompasses the visible surface, wherein at least one, preferably exactly one, sliding element is fastened in the at least one fastening recess, which is mounted in the fastening recess so that it can move in two mutually perpendicular directions parallel to the visible surface.
  • the invention can then provide that in a door leaf formed from such plastic hollow profiles, a cover plate of a door leaf is fastened to the at least one sliding element.
  • a door leaf according to the invention in which in the visible surface covered by the cover plate at least one of the hollow plastic profiles forming the door frame, preferably all of the hollow plastic profiles forming the door frame Plastic hollow profiles, at least one fastening recess is arranged, wherein in the at least one fastening recess at least one sliding element is fastened, which is displaceably mounted in the fastening recess, preferably displaceably mounted in two mutually perpendicular directions parallel to the visible surface, wherein the cover plate is indirectly connected to the door frame via the at least one sliding element.
  • the cover plate can be fixed to the respective thrust element in a shear-resistant manner, i.e. in a fixed position, e.g. by screwing or preferably by gluing or other material bonding.
  • the ability to move between the cover plate and the hollow plastic profiles is then achieved by the movable mounting of the respective thrust element in the hollow plastic profile.
  • the respective thrust element is mounted in the plastic hollow profile in such a way that it is not movable in a direction perpendicular to the visible surface of the plastic hollow profile or is only movable within the flexibility of the material.
  • a fastening recess can be designed as an opening in the visible profile wall of the plastic hollow profile, which surrounds/covers a hollow chamber.
  • the term hollow chamber is intended to include the fact that the hollow chamber in a single profile, which is not yet connected to others to form a frame, is open to the environment in the longitudinal direction of the profile, i.e. at both ends. At least in the cross-section perpendicular to the longitudinal extension, such a hollow chamber has a closed cross-section.
  • Such a fastening recess can be made during the manufacture of a hollow plastic profile, i.e. at a time before the actual door leaf is manufactured. As will be described later, this can also be done subsequently on an existing door leaf.
  • the invention offers the advantage that the sliding element provided enables a different thermal expansion of the cover plate on the inside and outside of the building, or that a thermal expansion of the at least one Cover plate relative to the plastic profiles of the door frame is possible without causing tension between the cover plates or the cover plate and the door frame.
  • the cover plate can make any length changes in any direction parallel to the cover plate plane relative to the plastic hollow profiles, as the cover plate moves the respective thrust element to which the cover plate is attached in the respective plastic hollow profile. The change in the cover plate dimensions therefore does not affect the plastic hollow profile.
  • the thrust element for the front door or door leaf also reduces deformation if the plastic profiles become deformed due to temperature differences. Stresses in both the transverse and longitudinal directions of an element (cover plate/hollow plastic profile), particularly parallel to the cover plate plane, are diverted to the thrust element without being transferred to the other element (hollow plastic profile/cover plate).
  • the sliding element therefore takes on the function of a stress equalizer, with the aim of preventing stress from being transferred to the frame construction of the door.
  • the front door is thus protected from deformation caused by weather.
  • the invention can provide that the plastic hollow profiles of the door frame, which are later assembled to form the door leaf or door panel, are machined on the visible surface on the outside and/or inside of the building, preferably by machining, e.g. drilling or milling.
  • a fastening recess can basically have any shape.
  • the fastening recess can form a round opening or a square opening in the profile wall of the hollow plastic profile that encompasses the visible surface.
  • a cover plate can be attached to several discrete locations, each of which has a sliding element, which are each indirectly connected to the hollow plastic profile via this, or are connected in the finished door leaf.
  • a fastening recess can also extend in a longitudinal direction, e.g. in the form of an elongated hole in the visible surface.
  • Such a fastening recess can form a fastening groove in conjunction with the edge of the recessed profile wall which surrounds the recess.
  • Such a groove can preferably extend in the longitudinal direction of the plastic hollow profile, but also perpendicular to it, or in any other direction.
  • such a fastening groove can be open at the end of the profile. The opening can, for example, be in the miter cut plane of the plastic hollow profile.
  • the groove edges or generally edges of the fastening recess preferably have a thickness corresponding to the opened profile wall and form, at least when viewed in cross section, opposing guide webs for a respective thrust element, against which the thrust element rests in a displaceable manner, in particular with the thrust element engaging around these guide webs.
  • a thrust element can have one groove, e.g. running all the way around the thrust element, or two opposing grooves open in opposite directions, with one said guide web lying in such a groove.
  • the invention can provide that several grooves are arranged one behind the other at a distance, in each of which at least one thrust element, preferably exactly one single thrust element, is slidably fastened or preferably that exactly one single fastening groove is provided in a plastic hollow profile, in particular which extends over the entire length of the plastic hollow profile, wherein preferably at least one thrust element, preferably also exactly one single thrust element, is arranged in such a single fastening groove.
  • This single thrust element can extend the length of the plastic hollow profile minus the displacement path to be taken into account in this direction.
  • the invention can provide, particularly in conjunction with a fastening groove, that the visible surface is completely removed except for areas that form lateral guide webs.
  • the sliding element is inserted into the existing fastening groove from the open end, in particular in such a way that the open visible surface is closed, preferably the stability of the profile is restored.
  • a push element is inserted into the plastic hollow profile from the visible side.
  • a push element can be placed on the fastening recess in a direction perpendicular to the visible surface and pressed into it, in particular with reversible deformation of the edge of the fastening recess and/or the push element at least on its side facing the recess.
  • the invention can provide that the cover plate is connected to the plastic hollow profiles in fixed bearings in some areas and in floating bearings in other areas.
  • the cover plate can preferably be screwed or glued, in particular directly to the plastic hollow profile or indirectly via spacers that simulate the distance between the plate and the plastic hollow profile at the location of a thrust element.
  • the at least one cover plate covering the visible surfaces of the hollow plastic profiles is connected in some areas in a non-displaceable manner to the frame-forming hollow plastic profiles and in some areas indirectly connected in a displaceable manner to the hollow plastic profiles via thrust elements.
  • the thrust elements thus form the floating bearings.
  • the cover plate is immovably connected, preferably by gluing, to a part number of all frame-forming Plastic hollow profiles, preferably a single vertically or horizontally running plastic hollow profile.
  • cover plate can also be immovably connected to an insulating material arranged between the plastic hollow profiles, further preferably wherein the area or areas between the plastic hollow profiles is/are filled with the insulating material, in particular wherein the insulating material is integrally connected to the plastic profiles, preferably by gluing.
  • the respective thrust element is designed as a plastic element, comprising two spaced apart, preferably at least partially parallel spaced apart plates, which are connected by at least one spacer running between them in the spacing direction, wherein the plates form at least one groove between them on their peripheral edge, by which the opening edge / guide web of the at least one fastening recess is enclosed.
  • At least one hollow chamber is formed in the thrust element between the plates, in particular in connection with the at least one spacer.
  • Such a hollow chamber can produce an improved insulating effect of the thrust element, which is particularly advantageous since the opening of the visible surface may reduce the insulating effect of the hollow chamber of the plastic hollow profile underneath. The thrust element can thus compensate for this lost insulating effect.
  • a hollow chamber in the thrust element is also understood to mean that the hollow chamber is open at two ends that are spaced apart in a longitudinal direction of the thrust element.
  • the invention can provide for these ends of the thrust element to be closed, e.g. by wall areas or plugs that are inserted into the open ends of the hollow chamber.
  • the invention can also provide that an insulating material is introduced into a hollow chamber of the thrust element.
  • this can be a foaming material that is injected into the hollow chamber, e.g. a Polyurethane foam. Injection can be done through one or both open ends.
  • the invention can also provide for the areas of the hollow chamber opened by the at least one fastening recess located in the plastic hollow profile to be filled with an insulating material, in particular after the at least one fastening recess or groove has been created.
  • This can preferably be a flexible insulating material, e.g. an insulating wool such as glass wool or rock wool, in particular in such a way that the insulating material can adapt well to the thrust element used and does not hinder the ability to move.
  • a thrust element If viewed in cross-section, its plates form two main webs spaced apart from one another. These main webs are connected to one another by intermediate webs formed by the at least one spacer, preferably with the main webs having the greater wall thickness/larger cross-section in relation to the intermediate webs.
  • the main webs lie parallel to one another at least in some areas, in particular in a central area of their total extension.
  • a guide groove is formed in each case, in which a guide web forming the edge of the opening of the fastening recess, in particular the fastening groove, lies.
  • the depth of the guide groove corresponds, preferably at least, to the thickness of the profile wall on the outside of the building or on the inside of the building that surrounds the visible surface of the hollow plastic profile.
  • both free ends contact the guide web or edge of the fastening recess, preferably thereby preventing any movement of the thrust element perpendicular to the visible surface.
  • the thrust element can preferably be designed as an elongated hollow plastic profile, in particular as an extruded hollow plastic profile.
  • the original visible surface of the plastic hollow profile after machining, preferably by cutting functions as a guide profile in which the thrust element lies and can be moved
  • the sliding element then forms at least part of the new visible surface of the door frame profile.
  • the guide webs on the hollow plastic profile extend at least 10% and no more than 90% into the guide groove on the thrust element. This ensures that the thrust element is adequately fixed in the hollow plastic profile and at the same time there is sufficient space to enable the sliding movement of the thrust element and the cover plate connected to it or to be connected.
  • the opposing thrust elements have a gap between them at the corners of the frame. This is particularly intended for thrust elements that are the only ones to extend in a fastening groove of the hollow plastic profile up to the gap (or twice the gap size) over its entire length.
  • the invention can provide that, viewed in cross section, the main web of the thrust element located in the hollow plastic profile is set back in length at the location of at least one of its free ends, preferably at the location of both free ends, compared to the free end of the other main web. This makes it easier to insert a thrust element into the opened fastening recess/groove.
  • the main web of the thrust element located in the hollow plastic profile can run at least partially in the direction of the other main web at the location of at least one of its free ends, preferably both free ends, in particular bent from a previously parallel course to the other main web, e.g. in the area of the middle of the main web, in the direction of the latter. This also facilitates assembly through the visible surface, especially if the distance between the main webs, in particular in the middle area, is greater than the distance between the free ends.
  • the cover plate on the inside of the building which forms the visible surface of the front door, can completely cover only the insulation material, but preferably not the visible surfaces of the hollow plastic profiles, and is preferably bonded to the insulation material in a material-to-material manner, preferably as an adhesive connection.
  • the cover plate covers the insulation material and the plastic hollow profiles of the door frame in particular completely and is connected in a material-to-material manner, preferably adhesively, both to the insulation material and to the at least one thrust element, preferably to all the thrust elements used. Since the cover plate on the outside of the building is generally exposed to larger temperature fluctuations, it can undergo the associated dimensional changes without transferring forces to the plastic hollow profiles of the frame, since the cover plate is connected to the respective profile via the thrust element(s).
  • the cover plates consist of aluminum, plastic or GRP plates or composite plates. It is provided that the frame receiving the at least one thrust element is preferably made of plastic hollow profiles.
  • the invention can provide that when the cover plate is mounted, the dead weight of the cover plate rests at least predominantly on the lower plastic hollow profile of the door frame.
  • the cover plate can be fixedly attached to this and displaceable to all the others via at least one sliding element.
  • the cover plate can be fixedly attached to a single plastic hollow profile of the frame and displaceable to all the others in sliding elements.
  • the invention also opens up the possibility already mentioned at the beginning of a method for the subsequent production of a door leaf from an existing door leaf according to claim 14.
  • the design also allows a conventional front door to be retrofitted without the use of stress-compensating sliding elements. Even in the event of damage, the front door can be retained in this way and the front door or its door leaf can be repaired using the variant described below.
  • the weather-side cover plate of the front door is removed and the exposed frame surfaces are milled to remove material, so that a recess is created in each hollow plastic profile that takes on the function of a fastening groove.
  • the recesses of all hollow plastic profiles can merge into one another in the corner areas. In such a case, a frame-shaped, circumferentially self-contained fastening recess or fastening groove.
  • the material is cut back so that longitudinal guide bars remain on both sides. Since it is not possible to slide the free profile ends onto the fully welded door frame, the sliding elements for retrofitting are designed so that they can be inserted into the recess from the outside.
  • the two main webs are arranged in an area between their free ends, in particular a central area, at a greater distance from each other than at the free ends, and the free ends of the main web on the inside of the building, which is therefore located in the plastic hollow profile, each end in a clamping area at an angle to the other main web.
  • the opposite free ends of the main web on the outside of the building and the main web on the inside of the building can preferably have ends of the same length on one side.
  • the main web is shorter at its free end on the inside of the building than the free end on the outside of the building.
  • the edge of the push element with the equally long free ends of the push element can be pushed onto a guide bar and the push element can be swung into the fastening groove to close it.
  • the free end of the shortened main bar on the inside of the building can swing past the guide bar.
  • the push element is firmly seated by a transverse push by the fitter so that the guide bar is firmly fixed between the free end of the main bar on the outside of the building and the internal clamping area of the shortened main bar on the inside of the building.
  • the construction of the free ends of the main webs of the thrust element is preferably dimensioned/designed/constructed by the tapered/slanted profile up to the clamping area in such a way that the open ends form the guide groove between them in such a way that the guide webs protrude into the guide groove by at least 10% and at most 90%. This ensures a minimum gap that the thrust element uses as a compensation path in order to compensate for the stresses resulting from temperature effects.
  • FIG. 1 a front door 100 comprising a frame profile 10 and a hollow plastic profile 20 forming the door frame with cover plates 40, 40' and with insulating material 50 in between is shown in section and in the closed state according to the invention.
  • the door leaf according to the invention results from the frame with cover plates and insulation.
  • the frame 10 can consist of a plastic hollow profile with a steel reinforcement 11.
  • the plastic hollow profile 20 has a fastening groove 25 in its outer visible surface as a fastening recess, e.g. which is formed by milling away the originally closed, externally facing surface 22 of the plastic hollow profile or also originally during the Profile production was formed.
  • the visible surface 22 on the outside of the building which is opened in the longitudinal direction, forms an undercut groove, preferably which extends at least in some areas, preferably essentially over the entire length of a plastic hollow profile 22, preferably on all four circumferential plastic hollow profiles 22.
  • An original hollow chamber in the plastic hollow profile can be opened up through the groove.
  • the sliding element 30 is pushed onto the guide webs 23, 24 which delimit the fastening groove 25 and which are part of the visible surface 22, and forms a positive connection with the hollow plastic profile 20.
  • the sliding element is preferably cut to length at 45 degrees at the ends. It also preferably extends almost over the entire length of a door frame profile, in particular over the length of a door frame profile minus a gap (possibly twice) to form an expansion gap 26 between sliding elements adjacent in the corners.
  • the pushed-in sliding elements therefore do not meet flush in the corners, but are spaced apart from one another by a gap 26.

Dimensional changes of the cover plate 40 connected to the respective sliding element 30 are therefore not transferred to the plastic hollow profiles, since in the event of a dimension change, the position of the sliding element in the door frame changes accordingly due to displacement in the fastening groove 25.
  • Warping of the door frame 20 due to temperature differences can thus be minimized or preferably prevented.

  • This allows the thrust element to have a ladder-like shape in cross-section.
  • the main webs correspond to the aforementioned plates and the intermediate webs to the spacer element, which here also encloses two hollow chambers in the thrust element.
  • the hollow chambers can be filled with an insulating material, e.g. foamed.
  • the free ends 34, 34 ⁇ , 35, 35' of the main webs form a guide groove 36 between them, in which the guide webs 23, 24 of the profile wall of the hollow plastic profile that encompasses the visible surface lie, preferably in a form-fitting manner.
  • the free ends of the main webs of the push element thus encompass the guide webs 23, 24.
  • the push element is slidably attached to the guide webs 23, 24.
  • the distance between the two outermost intermediate webs in the sliding element is smaller than the distance between the mutually facing end faces of the opposing guide webs 23, 24.
  • the difference between these distances defines the possible displacement path transverse to the longitudinal direction of the door frame profile.
  • the displacement path in the longitudinal direction is preferably defined by the distance between the adjacent sliding elements in the corners.
  • Figure 1b shows a further embodiment in a detailed view of the mounted sliding element 30 in section.
  • This embodiment provides a pivotable variant of the sliding element in the existing door frame in the event of retrofitting or repair.
  • the two main webs 31, 32 are arranged by the intermediate webs at a distance from each other that is greater than the thickness of the guide webs 23, 24, preferably with the free ends 34", 35" of the main web 31 on the inside of the building being angled in the direction of the opposite main web 32, in particular so that at the narrowest point between the straight free end 34, 35 of one main web 32 and the angled free end 34", 35" of the other main web 31, a clamping area 37, 37' is formed in cross-section, or a clamping line is formed across the extension of the thrust element 30. In the clamping area or on the clamping line, the distance between the free ends 34 and 34" or 35 and 35" can preferably be equal to the thickness of the guide web 23, 24 or preferably smaller than the thickness of the guide web 23, 24.
  • the opposite free ends 34/34" of the main web 31 on the outside of the building and the main web 32 on the inside of the building are of the same length on one side of the thrust element 30, in particular that they end in the same plane, and on the other side the free end 35" of the main web 31 on the inside of the building is shorter than the free end 35 of the main web 32 on the outside of the building, in particular that the free end 35" on the inside of the building is set back from the free end 35 on the outside of the building.
  • the distance between the ends 34 and 35 of the main web 32 on the outside of the building is selected such that this main web 32 cannot be pivoted into the fastening groove. In particular, however, the distance between the free ends 34" and 35" on the inside of the building is smaller as the distance between the free ends 34 and 35 on the outside of the building.
  • the edge or guide groove of the push element with the equally long free ends of the push element 34, 34" is pushed onto a guide web 23 and the push element 30 is pivoted into the fastening groove to close it.
  • the free end of the shortened main web 35" on the inside of the building can pivot past the guide web 24.
  • the push element is firmly seated by a transverse push by the fitter, in particular so that the guide web 24 is between the outside of the building open end of the main web 35 and the internal clamping point 37 ⁇ of the shortened main web 35" on the inside of the building.
  • the construction of the free ends of the thrust element 34", 35" is preferably dimensioned/designed by the course pointing in the direction of the opposite main web up to the clamping areas 37, 37' so that the free ends 34", 35" form the guide groove 36 between them in such a way that the guide webs 23, 24 protrude into the guide groove 36 by at least 10% and at most 90%.
  • the guide groove 36 is preferably considered between an intermediate web and the free end of the (possibly shorter) main web. This ensures a minimum gap between the guide web 23, 24 and the intermediate web, which the thrust element 30 uses as a compensation path in order to compensate for the stresses resulting from temperature effects.
  • Figure 2 shows a frame system 100 according to Figure 1 , in a further embodiment in which the frame is covered on both sides with aluminum facing shells 60.
  • the Figures 3 and 4 show a front door 100 after Figure 1 in the top view in the corner or mitre area.
  • the thrust element provided allows for different thermal expansion of the cover plate on the inside and outside of the building without causing stress. In the longitudinal direction, this results in a displacement path in the thrust element which corresponds to the gap width between the thrust elements 30 opposite each other in the corners, viewed in the longitudinal direction of the respective thrust element 30.
  • the sliding element reduces the deformation of the front door if temperature differences cause the plastic profiles or the Cover plates. Tensions in both the transverse and longitudinal directions are reduced or prevented by the ability to move between the sliding element and the hollow plastic profile of the door frame.
