Definitions

  • the invention relates to a door blank, in particular a front door or front door blank, having a core and a frame, the frame comprising a plurality of elongated members extending around the core and thus substantially defining the periphery of the door blank.
  • the plurality of elongated elements in this case comprises at least one composite material exhibiting, elongated reinforcing element.
  • Conventional door blanks belonging to the upper quality class are typically made of high quality and relatively expensive materials.
  • Such high quality materials such as Although natural wood and steel ensure a certain quality of the product, their use at the same time contributes to higher production costs and an increased burden on the environment through a higher demand for wood stocks and higher energy consumption.
  • a door blank of the type mentioned is installed, for example, in a door, which is sold by the company VARIOTEC under the name "outer door type All Weather VS".
  • two reinforcing elements made of a metal-free fiber-plastic composite are provided on the lock side of this door blank.
  • the two reinforcing elements have the form of flat strips.
  • the flat strip-like reinforcing elements do not extend over the entire thickness of the door blank, but they are instead inserted in recesses which are provided on two opposite sides of elongated wood elements.
  • this construction is relatively complex and also still provides no satisfactory stability with increased demands on this.
  • the present invention is therefore an object of the invention to produce a high-quality door blank from inexpensive and / or environmentally friendly materials, the production over that which is known from the prior art, simplified and the stability of the door blank is to be further increased.
  • the at least one elongated reinforcing element comprises an outer area formed of a composite material, in particular of a fiber-reinforced composite material, and further comprising at least one inner area which is free of composite material, wherein the outer region - viewed in a sectional plane orthogonal to the longitudinal extension direction of the at least one elongate reinforcing element - surrounds the at least one inner region, at least in sections.
  • the composite according to the present invention extends not only on at least one side of the door blank; rather, an essential component of the door blank itself, namely at least one of the elongate elements that extend around the core, at least in regions, consists of a composite material, in particular a fiber-reinforced composite material.
  • the reinforcing elements according to the invention can be prefabricated separately from the actual production of the door blank. If necessary, they only have to be cut to the correct size. Then, instead of from the state of the Technique known elongated elements that do not comprise composite, can be used. The additional step of coating at least one side of the door blank with a layer of fiber-reinforced composite material can thus be dispensed with during the production of the door. The production is therefore easier and cheaper.
  • the door blank according to the invention has the advantage that the at least one reinforcing element contributes to a significantly higher stability of the door blank.
  • the flat-strip-like reinforcing elements of the VARIOTEC door blanks are in fact designed as solid profiles. They thus offer, despite the use of a relatively large amount of expensive fiber-plastic composite material, only a relatively low resistance to certain types of stress. In particular, bending loads about an axis orthogonal to the longitudinal extension direction of the reinforcing elements can only be insufficiently absorbed by these flat strip-like reinforcing elements.
  • the reinforcing element according to the invention which has a "hollow profile", i. in which a composite outer region surrounds a composite-free inner region - at least in sections - a markedly higher resistance to such types of stress, without, however, needing to significantly increase the amount of the composite material to be used.
  • the at least one reinforcing element extends substantially over the entire thickness of the door blank, the expense and thus the costs during assembly of the door blank can be reduced.
  • the production of the reinforcing element according to the invention is usually more complicated than the production of a flat strip-like reinforcing element with a solid profile, as already mentioned above, the reinforcing elements according to the invention can be used as a substitute for the conventionally used, composite-free elongated elements, so that no additional processing steps during installation of the door blank are required.
  • corresponding recesses in the elongated wood elements must first be provided, into which the flat strip-like reinforcing elements then have to be inserted.
  • door blank is understood to mean an article which, in contrast to a manufactured door comprising a door blank, does not yet have fittings and also no cover layer or cover layers which extend over the front and / or sides Rear side of the door blank extends or extend.
  • composite material or “fiber-reinforced composite material” is to be understood as meaning, in particular, a material which comprises (synthetic) resin or another plastic as an essential constituent and which contains fibers such as carbon fibers, glass fibers or Metal fibers, is offset, or in which such fibers are incorporated in the plastic.
  • surrounded is to be understood as meaning that the exterior area not only adjoins only the at least one interior area; Rather, this is to be understood by the fact that the outer region has a - arbitrarily shaped - concave portion which is formed around a correspondingly convex shaped counter portion of the inner area around.
  • the outside area can also completely surround the at least one interior area.
  • the concave portion of the outer region can be shaped, for example, round or oval, but it is generally advantageous if it is angular, preferably rectangular.
  • elongated with regard to the elongated elements surrounding the core is to be understood as meaning that the corresponding element has a clearly recognizable preferred direction into which it extends, preferably in a straight line.
  • the corresponding element may also have a kink or a curve or bend, so that its main extension direction is not rectilinear.
  • the "outer region" of the reinforcing element is to be understood as meaning an integrally formed section of the reinforcing element.
  • the at least one elongated reinforcing element during assembly of the door blank according to the invention as a replacement for a conventional elongated element, which does not have a composite material
  • the at least one elongated reinforcing element has a rectangular, for example square, cross-sectional shape. It is preferred in view of a simple manufacture, although the at least one inner region has a rectangular cross-sectional shape. In principle, however, the at least one inner region can also have a different cross-sectional shape, such as, for example, a circular, semicircular or oval cross-sectional shape.
  • cross-sectional shape of the elongate reinforcing member or its outer portion or its at least one inner portion it is always meant the cross section in a sectional plane orthogonal to the longitudinal extension direction of the corresponding reinforcing member.
  • the exterior region may surround the at least one interior region on at least two sides, preferably on at least three sides, more preferably on all four sides.
  • the at least one inner region is filled with a solid material, such as wood, the outer region can thus receive the material of the at least one inner region largely in a form-fitting manner.
  • the outer region surrounds at least 50%, preferably at least 75%, more preferably at least 90%, and most preferably 100% of the circumference of the at least one inner region.
  • the outer area completely surrounds the at least one inner area.
  • the outer area may also have the shape of a C-profile or a double-T-beam.
  • the outside area can also have several interior areas, of which at least one is completely surrounded by the outside area, whereas at least one other interior area is only partially surrounded by the outside area.
  • the outer area made of the composite material can be produced inexpensively by an extrusion method. With such an extrusion method, hollow profiles with almost any desired cross-sectional shape can be manufactured relatively easily and thus inexpensively in large numbers.
  • the at least one elongate reinforcing element can have a plurality of interior areas, for example four interior areas.
  • the interior areas could be spatially separated from each other by at least one divider.
  • the at least one separating web is preferably formed from the composite material, in particular fiber-reinforced composite material, of the outer region, and preferably integrally with the remaining outer region.
  • the at least one separating web is part of the outer region of the elongate reinforcing element.
  • the at least one separating web is formed from a composite material-free material. In this case, it is part of the interior, the interior then comprising several different composite-free materials
  • the at least one interior area is free of any solid material.
  • the at least one interior area can be filled, for example, only with air. Under certain circumstances, however, this can lead to a reduced insulation capability of the door blank, in particular to sound. Therefore, it is alternatively proposed that the at least one inner region is filled with a solid material, which is not a composite material.
  • This may be e.g. to act a, preferably light, wood, which has correspondingly good sound-insulating properties and is of lesser weight and also more cost effective than the composite material.
  • Other fillers may be, for example, perlite or plastic and / or metal foams. Foams are therefore particularly well suited, as they are relatively light and provide good thermal insulation.
  • the at least one elongated reinforcing element contributes to the stability of the door blank when the core is surrounded by elongate reinforcing elements substantially all around its circumference.
  • This may be done in a similar manner as is known in the art of doors having a steel frame.
  • the elongate reinforcing elements according to the present invention have various advantages.
  • composite materials in particular fiber-reinforced composite materials, are significantly lighter than steel, with at the same time, or even better, mechanical or thermal resilience.
  • the thermal expansion of composites is in most cases much lower, and thus more favorable, than in steel.
  • the thermal expansion of the materials used can play a role, since it can lead to distortion of the door in the use of materials with a large coefficient of thermal expansion, such as steel, under severe temperature fluctuations under certain circumstances.
  • the core of the door blank will in most cases be substantially rectangular, with two lateral edges, an upper edge and a lower edge. Such cores are easy to cut and fit well in shape to doors, which are also usually also rectangular.
  • the at least one elongate reinforcing element extend substantially either parallel to the two lateral edges of the core or parallel to the upper and lower edges of the core.
  • the core is surrounded by the elongated reinforcing elements substantially all around its circumference, two elongated reinforcing elements could extend parallel to the lateral edges of the core, whereas two further elongated reinforcing elements extend parallel to the top and bottom edges of the core.
  • the two elongated reinforcing elements extending parallel to the lateral edges of the core may sandwich between the two elongate reinforcing elements extending parallel to the upper and lower edges of the core, preferably directly adjacent thereto adjacent; or the two elongate reinforcing elements extending parallel to the upper and lower edges of the core, can sandwich and preferably also directly abut the two elongate reinforcing elements extending parallel to the lateral edges of the core.
  • no such elongate reinforcing element could be assigned to one or more edges of the core, so that, for example, only one edge or two or three edges of the core is reinforced with such elongate reinforcing elements.
  • the at least one elongate reinforcing element can be thought of forming the at least one elongate reinforcing element shorter than half the length of the respective edges of the core to which it extends in parallel.
  • angle corner pieces can also be provided in one piece.
  • a door according to the invention will preferably have four angle corner pieces, but possibly only two or three. The two legs of an angle corner piece may have the same length.
  • the at least one elongate reinforcing element is at least half as long, preferably at least 3 ⁇ 4 as long and more preferably at least as long as the respective edges of the core to which it is extends parallel.
  • the door blank is formed substantially rectangular, with a hinge side and a parallel thereto extending lock side, and with a head side and a parallel extending bottom side, which is at least one elongated Reinforcement substantially parallel to the hinge side and the Schtossseite of the door blank or parallel to the head side and the bottom side of the door blank extends.
  • the at least one elongated reinforcing element extends substantially over the entire length of the respective sides of the door blank to which it is parallel. As a result, however, one would see a piece of the elongated reinforcing element on the corresponding sides of the door blank from the outside, which might not be visually appealing.
  • the production of the finished door from the door blank in the edge region of the door blank still hinges and / or a pawl and possibly a lock are to be mounted. Because the subsequent Processing of a composite material, in particular of a fiber-reinforced composite, is difficult, it is preferable to provide wood in the outer region of the door blank, as in conventional doors also.
  • the at least one elongated reinforcing element is shorter than the respective sides of the door blank to which it extends in parallel.
  • the at least one elongate reinforcing element is arranged between the core and at least one additional elongated element, which is not an elongated reinforcing element.
  • the additional elongate member may be substantially made of wood and serve to provide additional hardware at the appropriate location of the finished door, such as a vertically extending rod for closing and / or pressing the door.
  • the at least one elongated reinforcing element extend over the entire thickness direction of the door blank.
  • the at least one elongated reinforcing element extends over the entire thickness direction of the door blank, this relatively much force acting on the door blank record.
  • the at least one elongate reinforcing element can be made correspondingly narrow.
  • the invention relates to a door with a previously described door blank.
  • the door preferably comprises at least one front-side cover plate, which extends substantially over the entire front side of the door blank, and / or a rear-side cover plate, which extends substantially over the entire rear side of the door blank.
  • the door can already be provided with fittings.
  • the door may have a door lock, a door handle and / or fittings for door hinges.

  • the edges 112-118 of the core 110 in this embodiment all directly adjoin each one of the reinforcing elements 124a-124d.
  • the core 110 of the door blank 100 is thus on all sides of the elongated reinforcing elements 124a-124d surround. These can absorb very well acting forces due to their arrangement on the finished door.
  • the elongated elements 122a-122d are arranged. These, like the elongated element 122e, e.g. made of a solid natural wood, which gives the finished door to the outside a visually solid and high-quality impression and also relatively easy to work, for example, to attach fittings or install a lock.
  • the respectively outermost elongated element 122b and 122d extends over the entire length or height of the door blank. An observer will most likely be able to see the hinge and lock side of the four narrow sides of the built-in, finished door. Since the door blank in this embodiment on the hinge and the lock side has no joints, the observer of the finished door can thus be given the impression that the door blank is made of a single, solid wood sheet.
