Definitions

  • the invention relates to a high-speed door.
  • High-speed doors are used, for example, on doors in warehouses so that they can be opened and closed quickly. These are doors with a flexible door leaf that is wound onto a shaft to open it. Such a door is made, for example, of WO 2016/131476 A1 Such doors are used, for example, to close cold storage or freezer rooms and must therefore have sufficient insulation properties.
  • the high-speed door has a flexible door leaf which is attached to a rotating shaft in such a way that it can be wound up by rotating the shaft.
  • the shaft is connected to a suitable rotary drive, for example an electric motor, and can preferably be driven in both directions of rotation so that the door leaf can be wound up and unwound again.
  • a suitable rotary drive for example an electric motor
  • the movement of the door leaf can be assisted by gravity or, if the weight of the door leaf is sufficient, it can also be carried out by gravity alone, at least in sections.
  • the door leaf is made of a felt material.
  • Felt has good insulation properties, sufficient flexibility for winding up and, in addition, good durability.
  • the felt material is provided with a vapor-tight coating on at least one surface.
  • the vapor-tight coating prevents moisture from penetrating the felt material through the surface. The penetration of moisture would be particularly problematic if used as a door that closes off a deep-freeze room, as the moisture could freeze in the felt material and the felt material would then no longer be sufficiently flexible for winding up. In addition, moisture would impair the insulation properties.
  • the vapor-tight coating is formed on at least one surface, preferably at least on the surface that faces a room with air humidity. When used as a cold room door, this is in particular the warm side of the high-speed door.
  • the door leaf is provided with a vapor-tight coating on each of its two opposite surfaces. This prevents moisture from penetrating the felt material on each side.
  • the vapor-tight layer also preferably has a smooth surface that is easy to clean and its appearance, for example the color, can be designed as desired.
  • the felt material is preferably a felt made of natural and/or artificial fibers.
  • Natural fibers can be, for example, wool fibers
  • the felt is preferably a wool felt, ie preferably a felt material that is made entirely from natural wool.
  • Such a wool felt has good insulation properties, can be used in a wide temperature range and, as a natural product, also has good ecological properties.
  • synthetic fibers can also be mixed into the felt material or the felt material could alternatively be made entirely from synthetic fibers, depending on the application.
  • the felt material is designed in such a way that it can be used in a temperature range of -40°C to +80°C, more preferably up to +150°C.
  • the door leaf is therefore suitable for use in cold or deep-freeze rooms as well as for applications in which heated rooms are to be closed, for example rooms for drying and/or curing certain products.
  • the vapor diffusion-tight coating is made of a plastic material and more preferably of a polyurethane material.
  • plastic materials have good elasticity or flexibility, which is necessary to enable the door leaf to be rolled up.
  • plastic coatings can be easily attached to the felt material and can ensure the desired vapor diffusion tightness. It is particularly preferably a polyether-based polyurethane. This has the desired cold resistance.
  • other materials that have the desired barrier effect against vapor can also be used.
  • These can be suitable plastic materials or metal-containing coatings. Multilayer coatings can also be used.
  • the vapor diffusion-tight coating is preferably designed in such a way that it has a flexibility that allows the door leaf to be rolled up even at temperatures below 0°C and more preferably at temperatures below -20°C. This flexibility or elasticity preferably ensures that the door leaf can be rolled up even in curvature radii of less than 10 cm without the coating breaking or tearing. The desired elasticity at low temperatures enables the high-speed door to be used to close deep-freeze rooms.
  • the vapor-diffusion-tight coating is UV-stable. This can be ensured by an additional surface coating or, in the case of a single-layer coating, by a suitable coating material.
  • the coating is considered UV-stable if it has a durability that is usual for such high-speed doors when exposed to daylight and direct sunlight. This is preferably at least five years, more preferably more than ten years.
  • the UV stability also ensures color stability of the coating material, so that the optical properties of the door leaf do not change substantially over its service life, even when exposed to sunlight.
  • the vapor-diffusion-tight coating is glued to the felt material and/or cast or melted onto the felt material.
  • the coating material can be applied in liquid or pasty form to the surface of the felt material and possibly pressed onto it before it then takes on its final strength. This can be done by cooling or chemical curing.
  • the coating material can be solvent-based. It can be applied, for example, using calender rollers.
  • the side edges of the felt material are further preferably sealed, preferably sealed with a plastic material. If both surfaces of the felt material are provided with a coating, the free side edges of the felt material remain, which can then be closed by a seal. But even if only one surface of the felt material is provided with the coating, it can be expedient to additionally seal the side edges.
  • the sealing is preferably carried out with a material that corresponds to the material of the coating or has similar chemical properties.
  • a liquid sealing material is particularly preferably used, which can penetrate into the structure of the felt material from the side edge and hardens within the structure, thus sealing the side edge.
  • a liquid plastic such as liquid silicone could be used for this.
  • the seal for the side edges is also preferably made of a material that is vapor diffusion-tight.
  • the side edges are located in the area of a door frame, they are exposed to less significant temperature differences, so that in individual cases less condensation of moisture is to be expected in these areas, so that the edge sealing can in individual cases be less diffusion-tight than the coating of the surfaces.
  • the door leaf can have at least two interconnected layers of felt material, which are preferably glued together.
  • the formation of several layers of felt material enables, on the one hand, different felt materials to be connected to one another.
  • a double-sided coated door leaf from felt layers coated on one side by connecting, in particular glued, two felt layers, each provided with a coating on one surface, such as the vapor diffusion-tight coating, to one another on their uncoated surfaces.
  • the different layers of felt material can also be sewn together. If the coating is penetrated in the process, it is advantageous to cover the areas of the seams with another layer of vapor diffusion-tight material, in particular to glue them over. In a similar way, other production-related breaks in the coating can also be subsequently closed or sealed.
  • the door leaf can be designed as a double door leaf.
  • a double door leaf has two door leaf parts which are arranged in such a way that they extend parallel to one another and are spaced apart from one another in a direction transverse to their surface. In this way, a cavity is formed between the two door leaf parts.
  • the two door leaf parts are connected to one another at the lower end. This is preferably done in an arc-shaped deflection of the door leaf parts so that the two door leaf parts can be made from one piece.
  • a corresponding door leaf material is folded over by 180 degrees in the area of the deflection so that two spaced-apart, parallel-extending door leaf parts are created, which are connected in the area of the deflection by a substantially semicircular cross-section.
  • a running weight can be arranged in the area of the deflection, which preferably extends essentially over the entire width of the door leaf.
  • the running weight weighs down the door leaf so that the door leaf parts are always kept stretched. It also supports the unwinding of the door leaf because it pulls the door leaf downwards due to its weight.
  • a design without a running weight is also possible.
  • Such a double door leaf has better insulation properties on the one hand, but on the other hand it also enables it to be rolled up and pressed onto a door frame very easily.
  • One of the door leaf parts is preferably connected at its upper end to the at least one rotatable shaft in order to be able to wind up the door leaf.
  • This is preferably the door leaf part which is further away from a door frame.
  • the other door leaf part is preferably fixed at its upper end.
  • the door leaf is preferably fixed in an area of the upper end of the door frame, more preferably in the area of the horizontal upper part of the door frame.
  • a door leaf designed and arranged in such a way is wound up in such a way that the first door leaf part is wound up on the shaft and the deflection moves upwards. This means that the door leaf part fixed at the upper end is unrolled or lifted off a door frame from its lower end when it is wound up.
  • a double door leaf can be designed in such a way that the two door leaf parts are of different thicknesses.
  • the door leaf parts are defined as those surfaces which, when closed, extend between the top and bottom of the door.
  • the different thicknesses have the advantage that, for example, the side of the door leaf facing a cold area can be made thicker and thus have better insulation properties, while the second door leaf part, which faces a warmer area, can be made thinner in order to reduce the mass of the door leaf for winding up.
  • the different thicknesses of the door leaf parts can be realized, for example, by a multi-layer structure in which the thinner door leaf part has one less layer of material or layer of felt material than the thicker part.
  • the thicker door leaf part can be made of two layers and the second layer of felt material can end in the area of the lower end of the door leaf, in particular in the area of the deflection, while the first layer of felt material is passed through and also forms the second door leaf part.
  • This can also be achieved in a corresponding manner with more than two layers.
  • Both door leaf parts can be provided with a vapor diffusion-tight coating on one or both surfaces, as described above.
  • door leaf part does not have to have vapor diffusion-tight coatings.
  • one door leaf part could have a different type of coating on at least one surface.
  • the door leaf part that is not exposed to cold If the wall is facing a cold room or is not adjacent to a cold room, it does not necessarily have to be vapour-tight on both sides or it may not have to be vapour-tight at all.
  • the high-speed door has a door frame against which the door leaf rests in a sealed manner when closed.
  • a contact area of the door leaf rests in a sealed manner on the door frame.
  • the door leaf can be guided in a guide, whereby the guide can be designed, for example, such that one side of the guide presses the door leaf against the door frame when closed.
  • the door frame and the door leaf can be designed such that the door leaf adheres to the surface of the door frame in order to achieve the sealed arrangement. This can be done, for example, by magnetic forces.
  • Such a design has the advantage that the door leaf and the door frame can be designed such that the door leaf rests on the outside of the door frame and can move freely in a direction away from the door frame.
  • This is an advantage in cold rooms, for example, since such a high-speed door can be opened from the inside by pushing it away from the door frame even if the drive fails. Damage to the door leaf is also prevented if, for example, a forklift truck accidentally drives into the closed door. In such a case, the door leaf can swing away from the door frame without having to be wound up.
  • the gate frame can have permanent magnets. These can be embedded in the gate frame or applied as a magnetic strip to the surface of the gate frame.
  • the permanent magnets are preferably arranged on the vertical sides of the gate frame over the entire height of the gate, so that a tight fit of the door leaf to the door frame can be achieved over the entire height.
  • ferromagnetic metal elements are arranged in the door leaf at least in one contact area in such a way that the door leaf is held magnetically in contact with the door frame when it is closed.
  • the contact areas of the door leaf preferably extend along the side edges of the door leaf over its entire height.
  • the metal elements are preferably arranged distributed over the entire height so that they can adhere to correspondingly distributed magnetic elements or permanent magnets.
  • a large number of individual metal elements for example metal plates or metal plates, are arranged in the door leaf, which are movable relative to one another.
  • the metal elements do not impair the flexibility of the door leaf and do not hinder winding.
  • the metal elements are further preferably embedded in the felt material or located inside the felt material so that the contact area on its surface is not impaired by the metal elements and a tight fit to the door frame can be achieved in this area due to the flexibility of the material.
  • pockets in which the ferromagnetic metal elements are arranged can preferably be formed in the interior of the felt material adjacent to at least one side edge, preferably adjacent to both vertical side edges.
  • the pockets can be made, for example, as incisions from the side edge. Metal plates can be inserted into these incisions from the side edge. After the metal elements have been inserted, these pockets are preferably sealed or glued to the side. In this way, the metal elements are held securely in the pockets inside the felt material.
  • the seal is preferably the same seal with which the entire side edge of the felt material is sealed, i.e. as described above, preferably a seal which is applied in liquid form to the side edge. and can therefore run into the bag and close or seal it securely.
  • the high-speed doors shown have a door frame 2, which consists of two side frame parts 4, which extend essentially vertically, and an upper horizontally extending frame part 6.
  • a rotatable shaft 8 is arranged, which extends horizontally and is driven by an electric drive motor 10.
  • the high-speed gate according to Figure 1 furthermore has a flexible door leaf 12, which is connected at its upper end to the shaft 8, so that the door leaf 12 can be wound up on the shaft 8 by rotating the shaft 8.
  • the door leaf 12 is made of a felt material in a flexible manner, as will be explained below with reference to the Figures 6 to 8 described in more detail.
  • a simple door leaf is provided, ie there is a single door leaf part which comes into contact with the door frame 2 and can be wound onto the shaft 8.
  • a door leaf 14 is used, which is designed as a double door leaf.
  • the door leaf 14 is formed from a door leaf web, which is deflected or folded over by 180 degrees at the lower end, so that the Figure 4 and 5 forms a loop shape that can be seen in the side view.
  • two door leaf parts 16 and 18 are formed in the closed state, which are connected to one another at the lower end via a deflection or a bend 20.
  • the first door leaf part 16 which is located closer to the door frame 2 or comes into contact with it, is fixed at the upper end 22 to the upper frame part 6 of the door frame 2.
  • the upper end of the second door leaf part 18 is connected to the shaft 8 or is wound up on the shaft 8.
  • the second door leaf part 18 is wound up and at the same time the first door leaf part 16 is pulled off the door frame 2 from its lower end and pulled upwards.
  • the deflection 20 or the arch 20 also moves upwards and the gate opens.
  • the shaft 8 is turned in the opposite direction and the gate slides downwards again or falls downwards due to the force of gravity.
  • a magnetic holding device is provided in this embodiment.
  • permanent magnets in the form of magnetic strips 26 are arranged in the two side frame parts 4. These magnetic strips can also be designed as magnetic strips on the surface of the side frame parts 4.
  • the door leaf 14 rests on the surface of the side frame parts 4 with lateral contact areas 28, which border on the side edges of the door leaf.
  • ferromagnetic metal elements in the form of metal plates 30 are arranged in the interior of the first door leaf part 16, as in Figure 8 you can see.
  • Figure 8 shows a schematic section of the door leaf part 16.
  • the metal plates 30 are attracted by the magnetic force of the magnetic strip 26, so that the door leaf part and thus the entire door leaf 14 is held on the door frame 2.
  • the door leaf 14 with the door leaf part 16 only rests on the surface of the door frame 2.
  • This is an advantage, for example, in cold stores or cold storage rooms, as the door can always be opened from the inside.
  • the door can also open if a transport device such as a forklift truck accidentally drives into the door from the inside.
  • the door leaf 14 then simply swings open in the direction of arrow B and then falls back against the door frame 2, where it is then held tightly in place again.
  • the metal plates 30 at the lower end of the door leaf 14 are pulled one after the other in a horizontal direction from the door frame 2 or the side frame parts 4.
  • the arrangement of a large number of metal plates 30 ensures the mobility of the door leaf 14, which is necessary for winding up.
  • the design of the door leaves 12, 14 is described in more detail on the basis of the Figures 6 to 8 which schematically show a section of a door leaf 12 or 14.
  • the door leaf is made of felt, in particular wool felt.
  • the door leaf 12, 14 has a wool felt layer 32, which is provided on its opposite surfaces with a coating 34 which is vapor-tight and firmly connected to the felt material.
  • This vapor-tight coating 34 can be made of polyurethane, preferably a polyether-based polyurethane, for example, and can be glued, cast or melted directly onto the surface of the wool felt 32.
  • the coating 34 is so flexible that the door leaf 12, 14 can be rolled up and down repeatedly, even at low temperatures.
  • either a thicker layer of wool felt 32 can be used or, as in the example according to Figure 7
  • two layers of wool felt 36 are connected to one another, for example glued, to form a door leaf.
  • the wool felt layers 36 are each coated on one surface with a 34 and the two wool felt layers 36 are glued together on the side that has no coating, so that overall a door leaf 12, 14 is created, which is provided on its two outer, opposite surfaces with a coating 34, as described above.
  • pockets 40 are cut into the felt material from the side edge 38.
  • the metal plates 30 are pushed into these pockets 40 from the side edge and are glued in the pockets 40, for example by sealing the side edges 38 with a liquid plastic compound.
  • such pockets 40 with the metal plates 30 are preferably only formed in the gate leaf part 16.
  • the pockets 40 are preferably cut into the wool felt layer 36, which later faces the gate frame 2, so that the metal plates 13 are located closer to the gate frame 2.
  • the door leaf 12 is preferably held in another way on the door frame 2, for example by additional pressing elements not shown here.
  • the magnetic holding device ie the magnetic strips 26 and the metal plates 30, can be dispensed with.
