Definitions

  • the invention relates to a door, in particular a roller door, according to the preamble of patent claim 1.
  • Such doors are realized, for example, as so-called roller doors, in which the door leaf forms a possibly multi-layered coil in the open position above the wall opening.
  • the door leaf can have a number of door leaf segments arranged one behind the other in the direction of door leaf movement.
  • At least one stabilizing device extending perpendicular to the door leaf movement, approximately horizontally or approximately perpendicular to the movement path, is arranged between two door leaf segments. The mutually facing edge regions of the door leaf segments, which extend approximately perpendicular to the movement path, are held on the stabilizing device.
  • the door leaf segments When entering the open position and in the open position itself, the door leaf segments are deflected. This section of the track is also referred to as the deflection section.
  • the door leaf segments are made of a flexible base material, such as polycarbonate, which allows the door leaf segments to bend following the deflection section.
  • These door leaf segments also referred to as discs below, thus form bending areas of the door leaf, at least in the area between the stabilizing devices.
  • the familiar roller shutters can also be used as so-called high-speed doors for closing industrial buildings.
  • the stabilization of the door leaf movement by the stabilizing devices arranged between the individual door leaf segments, together with the flexible design of the door leaf segments themselves, enables door leaf speeds of 2 m/sec or more during opening and closing.
  • Gates according to the preamble of patent claim 1 are in the DE 3609194 A1 and the DE 2707474 A1 described.
  • the object of the invention is to provide doors with door leaves having bending areas, in particular roller doors, whose external appearance is hardly affected even in high-speed operation and under demanding weather conditions.
  • This invention is based on the discovery that the hard coating successfully used in industrial sectional doors on a bending area subject to bending during door leaf movement leads to the formation of microcracks, which in many cases impair the external appearance more than the damage caused by door leaf movement without appropriate equipment in the bending areas and/or by weather influences.
  • the dynamic loads regularly occurring in the deflection area during the opening and closing movement lead to the observed defects.
  • a functional film i.e., a structurally coherent surface structure
  • the structural properties of the functional film can be adjusted to accommodate the regular dynamic loads during door leaf operation.
  • the films can be provided with appropriate deformability, In particular, they can be equipped with elastic deformability and/or extensibility, which can easily handle the alternating bending (stretching and compression) when passing through the deflection sections.
  • a boundary layer can be formed between the base material and the functional film, which also withstands the occurring load changes without damage.
  • the laminated film also counteracts noise development. This is evident, on the one hand, in the reduction of running noises generated during door leaf movement. On the other hand, a reduction in rattling noises can be observed when external pressure is applied to the door leaf in the closed position, particularly when a part of the door leaf that is in the bending area is mounted in a floating manner (see below). Furthermore, the laminated functional film can reduce noise emissions from a hall enclosed by the door leaf.
  • the functional film laminated to the base material according to the invention can impart a desired external appearance to the door leaf in addition to or as an alternative to the improved resistance to impairments of the external appearance. If the priority in selecting the functional film is to avoid impairments of the external appearance, it is preferred within the scope of the invention if a boundary surface of the functional film facing away from the base material has a higher scratch resistance according to DIN EN ISO 12137 than the base material.
  • the functional films can be designed to be transparent overall. However, the use of colored films is also conceivable, which can impart improved mechanical properties to the bending area in addition to the desired colorful impression.
  • the functional films can be mixed with coloring pigments and/or equipped with corresponding translucent tints. They can be equipped with various types of filters or mirror coatings. In regions with high solar radiation, a mirrored film provides protection from sunlight while simultaneously allowing light to enter.
  • a boundary surface of the functional film facing away from the base material can be at least partially mirrored and/or decorated with a pattern, such as a carbon-look, wood-look, or brushed aluminum pattern.
  • a corresponding design freedom can hardly be realized in an economically viable manner by selecting the base materials for the bending area, because these base materials, such as polycarbonate sheets, can only be obtained with color pigments or special features in very large quantities, so that a design of the optical appearance via the starting material for the bending area is hardly economically viable.
  • Functional films usable within the scope of the invention are available in a wide variety. If they have a thickness of 0.2 mm or less, in particular 0.15 mm or less, but at least 0.01 mm, preferably at least 0.04 mm, they can be laminated to the base material without significantly impairing the overall mass of the door leaf, but with sufficient mechanical stability to maintain the desired function.
  • the functional film can be laminated to the base material using an adhesive, such as a pressure-sensitive acrylate adhesive.
  • a suitable adhesive is characterized by sufficient elasticity while ensuring sufficient adhesion.
  • the functional film can also be repositioned.
  • the adhesive can be provided in the form of an adhesive layer of the functional film, which, after being laminated to the base material, forms a boundary layer between the base material and other film layers of the functional film.
  • the base material itself is provided with the adhesive before lamination.
  • the functional film can include a PVC layer.
  • Functional films suitable for manufacturing the inventive gates which are already equipped with a pressure-sensitive acrylic adhesive as a precursor, are offered under the trade names 3M Wrap Film 2080 and 3M Scotchcal Film Clear View 8150. These functional films comprise a cast PVC layer and a layer of a pressure-sensitive acrylic adhesive.
  • the cast PVC layer can have a layer thickness of 50 ⁇ m to 100 ⁇ m.
  • the adhesive layer can have a thickness of less than 30 ⁇ m.
  • the various functional films with a cast PVC layer and a pressure-sensitive acrylic adhesive are particularly advantageous in combination with a base material made of Polycarbonate is used.
  • the door leaf preferably forms a multi-layer coil in the open position.
  • 3M Obsidian Sun Protection Film comprises a clear first outer layer comprising polyethylene terephthalate (PET), a dye-added PET core layer comprising one or more dyes selected from the group consisting of Pigment Yellow 147, Pigment Red 177, Pigment Blue 60, Pigment Black 31, Pigment Red 149, and Pigment Red 122.
  • the films further comprise a second outer layer comprising PET.
  • the film is fade-resistant after exposure to 300 MJ/ m2 total irradiance integrated over the 259 nm to 385 nm band and time.
  • the Obsidian solar control film may optionally be laminated to the base material using a pressure-sensitive acrylic adhesive.
  • the door leaf comprises a plurality of door leaf elements arranged one behind the other in the direction of door leaf movement, at least one of which comprises a bending region, wherein at least one stabilizing device extending perpendicular to the direction of door leaf movement is arranged between two door leaf segments and the mutually facing edge regions of the door leaf segments are held on the stabilizing device and at least one edge region of at least one segment is held floatingly on the stabilizing device such that a relative movement of this edge region with respect to the stabilizing device is possible at least in the direction of door leaf movement. Impairment of the visual appearance of corresponding roller doors is reduced if the edge region of at least one segment, which can also be referred to as the bending region of this segment, is equipped with a functional film. In this case, the floating mounting can effectively reduce the abrasion marks in the edge region of the segment by means of the functional film.
  • hinge arrangements can be provided to guide the door leaf movement on edges of the door leaf that run at least partially in the direction of gravity in the closed position and are fastened to the door leaf, each of which can have a plurality of hinge members that are articulated to one another with respect to hinge axes that run perpendicular to the lateral edges and approximately parallel to the plane of the door leaf.
  • the space requirement in the open position is reduced by at least some of the segments of the door leaf being made of a flexible base material, such as a polycarbonate sheet, to provide bending areas. which, even in the open position, adapts to the coil to be formed, thus enabling a small spiral diameter in the open position.
  • the segments of the known gates can be equipped with a functional foil.
  • impairments of the segments occurring within the scope of this invention can already be reduced by using a functional film
  • impairments can also be prevented by floating mounting of the door leaf segments with respect to the stabilizing device, without thereby impairing the overall stability of the entire construction.
  • the floating mounting of the door leaf segments and the use of a functional film in the area of this floating mounting work synergistically to avoid visual impairments.
  • stabilizing devices and any existing joint arrangements form a stable framework via which forces arising during the door leaf movement can be transmitted, without the need for rigid fastening of the door leaf segments, which may be provided with a functional coating, to the stabilizing devices in order to stabilize the overall arrangement. Therefore, a floating bearing, which allows a relative movement of the edge areas of the door leaf segments with respect to the stabilizing device, can be realized without impairing the door leaf movement or the stability of the entire door construction.
  • the floating bearing allows for the absorption of any play or relative movements that may occur between the stabilising device and the door leaf segment during the door leaf movement, without causing damage or visual impairment to the door leaf construction due to excessive force.
  • the visual impairment can be additionally counteracted by equipping the door leaf segments with a functional film.
  • the floating bearing not only enables relative movement between the edge area of the door leaf segment and the stabilizing device in the direction of door leaf movement, but also, if necessary, in a direction parallel to the floating edge area or perpendicular to the direction of door leaf movement, so that even slight deviations of the door leaf movement from the specified path hardly cause damage to the door leaf segments.
  • a synergistic effect can also be achieved here through the use of a functional film proposed by the invention.
  • the relative movement of the floating edge region of at least one door leaf segment with respect to the stabilizing device is limited by means of a limiting arrangement, wherein the limiting arrangement becomes effective in particular in the case of a relative movement in a direction parallel to the direction of movement of the door leaf.
  • the limiting arrangement has an extension of the floating edge region in a thickness direction running perpendicular to the door leaf plane spanned by the door leaf movement direction and the stabilizing device, and a receptacle formed in the stabilizing device for the extension of the edge region held floating thereon, wherein the receptacle has an opening penetrated by a transition region of the segment between the extension and a region of the segment exposed outside the stabilizing device, the width of which opening in the thickness direction is greater than the thickness of the transition region in the thickness direction, but smaller than the dimensions of the extension in the thickness direction.
  • the stabilizing device is designed according to the WO 2018/219512 A1 expediently carried out by a stabilizing profile with a receiving area for receiving the extension of the edge area of the door leaf segment, wherein the receiving area of the stabilizing profile is adapted to the dimensions of the door leaf segment in such a way that the door leaf segment can be attached to the stabilizing profile.
  • a further limitation of the relative movement of the edge area of the door leaf segment with respect to the stabilizing device or the stabilizing profile can be achieved if the support is limited by a floor on the side opposite the opening, whereby the distance between the opening of the support and the floor in the direction of door leaf movement is greater than the length of the extension of the floating edge area in the direction of door leaf movement.
  • the difference in dimensions determines the possible play of the floating support of the edge area with respect to the stabilizing profile.
  • the door leaf segment is formed from a web-like material, wherein the extension of the door leaf segment can be formed by bending the floating edge region with respect to a bending axis running parallel to the stabilizing device.
  • the extension of the door leaf segment can be formed by bending the floating edge region with respect to a bending axis running parallel to the stabilizing device.
  • no additional component is required to form the extension of the door leaf segment.
  • the bending of the door leaf segment in the edge region running perpendicular to the direction of movement can be achieved, for example, by a roll-forming process.
  • the edge region of the door leaf segment can be bent back on itself, for example in the manner of a hook, in order to thus obtain an extension of the floating edge region in the thickness direction.
  • a method for producing a door according to the invention is essentially characterized by laminating a functional film onto a base material made of flexible material.
  • the functional film can have an adhesive layer with which it is adhered to the base material.
  • the functional film For lamination, the functional film, together with the base material, can pass through a nip formed between two rollers of a laminator.
  • a laminator To prevent bubble formation during lamination of the functional film, it has proven advantageous to divert fluids from a boundary layer formed between the functional film and the base material through fluid channels in the functional film. These fluid channels can be provided in the adhesive layer of the functional film.
  • the wall area of the door leaf segment is to be bent back onto itself in the manner of a hook as explained above, it has proven advantageous in the production of doors according to the invention if the functional film is laminated to a flexible base material in the form of a plastic sheet, preferably consisting at least partially of polycarbonate and/or SAN, and an edge of the plastic sheet equipped with the functional film is bent over along a bending line running parallel to this edge. If the segment prepared in this way is inserted into the stabilizing device, improved wear resistance can be achieved in the area of the floating bearing of the segment.

  • Fig. 1 shows two door leaf segments 110 and 120 of a door leaf 100 of a door according to the invention, arranged one behind the other in the direction of door leaf movement indicated by the double arrow P.
  • the door leaf segments consist at least partially of a flexible material and form bending regions of the door leaf.
  • At least one door leaf segment, preferably each door leaf segment, can be equipped with a functional film on at least part of its outer boundary surface.
  • a stabilizing device designed as a stabilizing profile 200 is arranged between the door leaf segments 110 and 120. The stabilizing profile 200 extends in a direction perpendicular to the direction of door leaf movement P, approximately in the plane of the door leaf.
  • An upper edge of the door leaf segment 120 is held on a further stabilizing profile 200, just as a lower edge of the door leaf segment 110 is also held on a lower stabilizing profile 200.
  • the stabilizing profiles 200 are attached to a joint arrangement 300 extending approximately parallel to the direction of door leaf movement or parallel to a lateral edge of the door leaf 100.
  • the joint arrangement 300 comprises a plurality of joint members 310 arranged one behind the other in the direction of door leaf movement and connected to one another in an articulated manner with respect to joint axes running perpendicular to the direction of door leaf movement P.
  • Three joint members 310 are arranged between each two adjacent stabilizing profiles 200. In other embodiments of the invention, only one or two or four or more joint members can be provided between the stabilizing profiles 200.
  • a stabilizing profile can also be provided in the region of each connection between successive joint members.
  • the hinge assembly has guide rollers 320 on its side facing away from the door leaf segments 110 and 120, which are rotatably mounted with respect to roller axes running parallel to the hinge axes.
  • the guide rollers 320 are arranged in pairs in the region of a hinge axis in such a way that they can accommodate a guide web between them and can roll on opposing boundary surfaces of the guide web, thus enabling guidance of the door leaf movement, as in the PCT/EP2019/058221 described.
  • an upper edge region 112 of the door leaf segment 110 extending parallel to the joint axes and parallel to the stabilizing profile 200 is arranged in a receptacle 240 of the stabilizing profile 200.
  • the upper edge 112 of the door leaf segment 110 is designed by bending the upper edge of the door leaf segment 112 onto itself as an extension in a door leaf plane perpendicular to the door leaf plane determined by the door leaf movement direction P and the stabilizing profile 200. Starting from the extension 112, the door leaf segment 110 extends downwards with a transition region through an opening 250 of the stabilizing profile 200 and is exposed outside the opening 250, as shown in Fig. 1 can be seen.
  • the door leaf segment 120 has an extension 122 accommodated in a receptacle 230 of the stabilizing profile 200. Starting from the extension 122, the door leaf segment 120 extends upwards with a transition region through an opening 225 and is exposed outside the opening 225.
  • the opening 250 is delimited by boundary surfaces 232 and 242, the distance between which in a direction parallel to the door leaf thickness direction is less than the thickness of the extension 112, but greater than the thickness of the transition region of the door leaf segment 110 between the extension 112 and the area exposed outside the stabilizing profile 200.
  • the opening 225 is delimited by boundary surfaces 212 and 222, the distance in the door leaf thickness direction being less than the thickness of the extension 122, but greater than the thickness of a transition region between the extension 122 and the region of the door leaf segment 120 exposed outside the stabilizing profile 200.
  • the stabilizing profile 200 is designed in two parts, consisting of two detachably connected parts 210 and 220.
  • the recess 240 at the lower edge of the stabilizing profile 200 is formed entirely by the first stabilizing profile part 210, while the receptacle 230 at the upper edge of the stabilizing profile 200 is formed by the two stabilizing profile parts 210 and 220.
  • a first boundary surface 212 of the mouth 225 is formed by the first stabilizing profile part 210, while a second boundary surface 222 of the receptacle 230 is formed by the second stabilizing profile part 220.
  • an upper edge of a shutter leaf segment can be inserted into the receptacle 240 in a direction parallel to the stabilizing profile 200, with a transition region between the extension 240 and a region of the shutter leaf segment exposed outside the stabilizing profile 200 passing through the opening 250.
  • the module thus prepared can be threaded into a guide device, which can consist of a guide web arranged between the guide rollers 320.
  • a lower edge 122 of the door leaf segment can be placed against a boundary surface 212 of the first stabilizing profile part 210 and the second stabilizing profile 220 can be clipped onto the first stabilizing profile 210 to form the mouth 225, which is penetrated by the transition region between an extension of the door leaf segment received in the receptacle 230 and a region of the door leaf segment exposed outside the stabilizing profile 200.
  • the distance between the opposing boundary surfaces 212 and 222, or 232 and 242, of the orifices 225 and 250, respectively, is greater than the thickness of the transition areas penetrating these orifices. This prevents a clamping effect in the transition areas.
  • the distance between the opening 225 or 250 and the bottoms of the receptacles 230 and 240 opposite the corresponding openings 225 or 250 is greater than the length of the extensions 122 or 112 in the direction of door leaf movement. This enables a relative movement of the door leaf segments 110 and 120 with respect to the stabilizing profile 200.
  • a sealing material can be arranged, which may swell if moisture penetrates.
  • a damping element 230 is arranged between the bent lower edge of the disc 120 forming the extension 122 and the lower boundary surface of the part 220 of the stabilizing profile 200.
  • This damping element 230 seals the disc 120 floatingly mounted in the stabilizing profile 200, and on the other hand, preloads the disc 120 floatingly mounted in the stabilizing profile 200, helps compensate for tolerances, and holds the disc 120 taut in its position.
  • the damping element 140 reduces noise that can occur when the bent lower edge of the disc 120 is moved in the receptacle 230 and strikes the lower boundary surface of the part 220 of the stabilizing profile.
  • the door leaf segments comprise two panes 120a and 120b, or 110a and 110b, which run essentially parallel to one another and are each designed as flexible polycarbonate panes.
  • the lower edges of the panes 120a and 120b are each provided with an extension formed by bending these edges, which are mounted in a floating manner in receptacles 230a and 230b of the stabilizing profile 1200.
  • the upper edges of the panes 110a and 110b of the lower segment are held in receptacles 240a and 240b of the stabilizing profile 1200.
  • An air cushion 180 which promotes thermal insulation, is formed between the panes 120a and 120b, or 110a and 110b.
  • the air cushion 180 is closed at the edges running parallel to the direction of movement P of the segments 120 and 110 by elastic pads 190 provided between the discs 120a and 120b or 110a and 110b.
  • These pads 190 can be designed as elastic bars.
  • elastic pads made of a foam material can be used, which are glued in or mechanically fixed.
  • the elastic design of the pads 190 also allows the necessary mobility when wrapping the door leaf into the spiral guide track when reaching the opening position.
  • fan-shaped plastic elements which are connected to each other like hinges, can be clipped onto the pane in the chamber 180.
  • the screws shown are designed to compensate for the offset between the pane and the stabilizing profile in the wall area. This can improve the sealing of the door leaf in the closed position.
  • the embodiment of the invention shown differs essentially from that shown in the Fig. 4 explained embodiment, the chamber 2230b of the stabilizing profile 2200, which serves to receive the extension 230b at the lower edge of the disc 110b, has a greater depth in the direction of door leaf movement than the chamber 230a, which serves to receive the extension 122a formed at the lower edge of the disc 110a.
  • the stabilizing profiles 3200 are constructed in three parts overall, with parts 3210, 3220, 3230 being constructed consecutively in the direction of the door leaf thickness.
  • the part 3210 which is located inside in the closed position of the door leaf, as is the part 3220 of the stabilizing profile 3200, which is located outside in the closed position, is made of a metallic material. This gives the stabilizing profile the necessary stability.
  • the parts 3210 and 3220 are connected to one another via connecting elements 3230 made of thermally insulating material, such as plastic.
  • a stabilizing profile 400 is provided between the stabilizing profiles 200 fixed to the lower and upper edges of the panes 110, 120, which is fastened exclusively to the joint members of the joint arrangement 300.
  • This additional stabilizing profile 400 can be positioned independently of the pane geometry and can be attached to position a lintel seal depending on the height of the wall opening.
  • the stabilizing profile 400 is equipped with a sealing element 410 on its side facing away from the panes 110, 120, while on the side facing the pane 120 it is designed with hose seals 420 that rest against the pane 120.
  • the additional stabilizing profile 400 is not fastened to the pane 120, it can be fastened to any joint members 310 regardless of the pane geometry.
  • the position of the seal 410 can thus be adapted to the height of the wall opening. This not only improves the sealing effect but also increases the overall stability of the roller shutter.
  • the invention is not limited to the exemplary embodiment explained with reference to the drawing.
  • the extensions in the area of the edges of the door leaf segments can also be formed by glued or welded piping.
  • the stabilizing profiles 200 can be designed as a single piece, so that the extended edges of the door leaf segments must be inserted laterally into the stabilizing profiles.
  • guide arrangements in which guide rollers are accommodated in a guide rail can also be used.
  • a contactless magnetic guide can also be used.
  • the functional films used according to the invention can also comprise so-called low-E films with a high degree of reflection. This allows good thermal insulation to be achieved with a comparatively thin pane thickness.
  • the stabilizing devices of doors according to the invention can also be covered with film to enable a uniform door leaf design.
