Definitions

  • the invention relates to a door, in particular a motor-driven industrial door, according to the preamble of claim 1.
  • roller doors Such generic industrial doors are used as so-called roller doors.
  • roller doors have a number of advantages, such as a clean, complete closure of the door opening, which optimally protects against heat losses, drafts, unauthorized entry, etc.
  • the disadvantage is that such roller shutters can only be moved at very low speed, partly because they have to be pulled up despite the considerable weight and, on the other hand, tend to buckle and tilt if the downward movement is too rapid. Therefore, such roller shutters are not suitable for bringing about a closure of the door opening when there is considerable traffic through the door opening. Therefore, such roller doors are often used in addition to so-called high-speed doors of a suitable construction, with the daytime
  • High-speed doors enable the climatic closure of the door opening and a comfortable passage, while at night the roller doors ensure permanent closure even against unauthorized entry.
  • the edge of the door opening must be supported on a shaft in order to prevent the profile strips or slats from sagging too much, especially when the door width is large.
  • the windings of the lamellar armor lie against one another under strong pressure and contract further in the course of the movement of the lamellar armor in accordance with the forces which occur, so that strong friction occurs under pressure between the windings.
  • the surfaces of the slats are exposed to heavy loads and become unsightly over time, especially if window openings or similar surfaces with particularly sensitive surfaces are provided in the gate.
  • a further disadvantage is that a safety gear is required for such rolling gates for safety reasons, since with them, for example if the drive shaft breaks, there is the possibility that the slatted armor will be pulled down by its own weight at high speed and thereby endanger people and things considerably .
  • the invention has for its object to provide a door with the essential advantages of conventional roller doors, but which can also be designed for high-speed properties and immediately opens the entire height of the door opening when opened, so that it is suitable for frequent passages with normally closed door .
  • This object is achieved by the characterizing features of claim 1.
  • the slats are arranged in the vertical direction of the door opening and form a laterally standing wrap, the entire passage height is immediately released when the slat armor is opened and an early passage is thus possible. Furthermore, the winding is not subjected to gravity transversely to its longitudinal axis. Rather, the slat armor can be supported in the manner of a sliding gate hanging on its upper edge, for example by conventional guide roller constructions, and is guided on its lower edge, so that when the slat armor moves, only acceleration and friction forces, but not gravity, have to be overcome.
  • the door can be designed with high-speed properties and can thus serve as a permanent, optimal closure of the door opening similar to a roller door, even if frequent traffic through the door opening is to be expected.
  • each door wing consists of two cloth-like plastic sheets with a front end construction. The plastic sheets extend from the strip-shaped end construction to the area of the side wall of the gate opening, where each sheet is individually wound on a winding shaft.
  • Such a door may be an alternative to the current high-speed elastic doors, but it cannot do the function of a roller shutter made of rigid profile strips or slats, because the plastic sheets obviously lack the suitability for this.
  • the good possibility of winding elastic plastic webs is, however, the main idea of this design principle.
  • a relatively good thermal insulation of the door material itself is achieved by the double arrangement of plastic sheets with an air cushion arranged between them, but this is again significantly impaired by the fact that there is no floor-side guidance and therefore a more or less wide floor gap must remain depending on the unevenness of the floor. Sealing by means of brushes or the like attached to the lower edge of the plastic sheets is difficult because the brushes do not allow the unobstructed formation of a clean winding in view of the low thickness of the plastic sheets.
  • a clean, faster and tilt-free running of the slat armor in the closing direction is guaranteed according to claim 5 in that the drive engages pulling in the area of the free edge of the slat armor in the closing direction.
  • the windings of the lamellar armor do not touch each other and are guided at a distance from each other in upper and lower guide profiles. This certainly precludes any damage from mutual contact and friction.
  • the windings between the guide profiles are exposed, ie are not wound on an inner winding shaft. Due to the rigidity of the lamellae on the one hand and the absence of the action of gravity transversely to the axis of the winding on the other hand, such guidance in the central region of the winding can be omitted with regard to the upper and lower guide profiles. This creates a cavity there that can be chosen to be relatively large without the winding diameter therefore becoming excessively large. Therefore, drive units such as, in particular, an electric motor can be arranged in the free interior of the winding, so that, despite a relatively larger diameter of the innermost winding, an overall extremely space-saving design results.
  • winding is arranged in a hinged box according to claim 5, access to the electric motor or the like inside the winding is particularly facilitated. When the gate is closed there is no wrap act so that the electric motor is completely freely accessible after opening the box and is available for maintenance and repair work.
  • a particularly tight closure of the door opening is obtained if, according to claim 6, the slats of the slat armor are connected to one another via sealing bands such as spring steel bands, steel-reinforced rubber bands or the like.
  • sealing bands such as spring steel bands, steel-reinforced rubber bands or the like.
  • a bottom band arranged on the bottom edge of the slat armor is provided, which engages in a narrow slot of a guide rail, a deflection of the slat armor transverse to the direction of movement, for example as a result of wind pressure, is practically completely avoided and at the same time good coverage of the Floor gap reached.
  • guide rollers of the lamellar armor are usually provided, which run in the bottom-side guide rail, as is known per se in sliding gates.
  • the guide rollers are mounted on corresponding retaining bolts on the underside of the gate segment, so that the slot in the guide rail must have a correspondingly large width.
  • a large width of the slot of the guide rail is ins Particularly disadvantageous in industry in particular for driving over the slot, in particular if, for example, pallet trucks with a small wheel diameter of 100 mm or even less are used, which should not feel that the slot is being driven over if possible.
  • the guide rollers are mounted on the end tape, which is fastened in the bottom of the lamellar armor and passes through the slot, so that it can be made extremely narrow. At the same time the occurrence of increased frictional forces due to sliding friction between the end band and the guide profile is reliably avoided.
  • the weight support of the lamellar armor is carried out via idler rollers which are arranged on its upper edge and run in a conventional carrier and guide rail.
  • a hindrance to the free running of the guide rollers by dirt accumulating on the bottom of the guide rail is avoided in that according to claim 12 there is a vertical distance between the lower edge of the guide rollers and the bottom of the guide rail, so that a pocket for receiving dirt that has penetrated is formed.
  • the narrow slot in the areas of the guide rail released by the guide rollers is covered by a spring element in order to minimize the entry of dirt, for example when a vehicle drives over it.
  • the spring element can be elastically displaceable by the rollers and / or the spring steel strip on the underside of the lamellar armor, so that the slot is automatically closed when the lamellar armor is moved into the open position and automatically when the lamellar armor is retracted into the closed position for the guide rollers and of the spring steel strip is opened.
  • the spring element in the region of its free end has a projection which engages in the slot when it is covered.
  • the upper surface of the projection then advantageously connects the two upper edges of the slot almost seamlessly, so that a practically continuous surface is created. This largely avoids the formation of a groove in which dirt could accumulate and fall into the guide rail if the spring element is pushed to the side by the guide rollers or the end band when the door opening is closed.
  • this type of bottom-side guidance is also important for use with conventional ones Sliding or rotary doors.
  • Gates with horizontally running slat armor result in the measures of claims 15 and 16 a particularly clean and simple guidance of the slat armor.
  • the opening speed with respect to the passage width of the door is twice as large as the speed of movement of each slat armor, and the passage opening is first opened in the middle of the door opening, so that particularly rapid passage is possible.
  • Frictional forces occurring due to the smooth running of the slat armor are low, the gate can be operated by hand even without a motor drive.
  • Figure 1 is a perspective view of a gate according to the invention in the closed position.
  • Fig. 2 is a sectional view taken along the line II-II in Fig. 1i
  • Fig. 3 is a partial sectional view along the line III-III. in Fig. 2i
  • Fig. 4 is a sectional view taken along the line IV-IV in Fig. 3i
  • Fig. 5 shows a detail of Fig. 1 in an enlarged view
  • Fig. 6a is a sectional view of the bottom region of the gate in the closed position to illustrate the guide device
  • Fig. 6b is a sectional view of the bottom region of the gate in the open position
  • Fig. 7 shows a further sectional view of the bottom region of the gate in the open position.
  • the illustrated embodiment of a door according to the invention has two lamella armor 2, 2 ', the free edges 4, 4' of which, in the closed position shown, lie against one another in the middle of a door opening 6, so that the door opening 6 is completely covered.
  • the following description relates to the lamellar armor 2 on the left in the figure, but also applies analogously to the lamellar armor 2 'on the right in the figure.
  • the slat armor 2 consists of vertically arranged slats 8 which can be angled relative to one another. In order to release the gate opening 6, the slat armor 2 is moved in the direction pointing to the left in the figure and opened into a winding 13 within a laterally arranged box 11 which can be hinged 10 wrap t (Fi g. 2, 3).
  • the section shown in FIG. 2 along the line II-II of FIG. 1 shows the spiral course of a lower guide profile 14 in which guide rollers 16 run, which are connected to the slats 8 via brackets 18 and an end band 20 (FIG. 6a ).
  • the spiral course of the lower guide profile 14 is selected so that when the lamellar armor 2 is wound up or unwound, contact between the lamellas 8 is excluded.
  • An electric motor 22 is arranged in the space remaining inside the winding 12 (FIG. 3) and is freely accessible when the
  • Lamellar armor 2 is in the closed position, ie there is no winding, and the hinged box 11 is open.
  • the electric motor 22 arranged above the cutting plane is connected to a drive roller 26 via a drive belt 24.
  • a second, concentric drive roller 28 is connected to this drive roller 26, in which a V-belt 30 runs (FIG. 3), which is connected to the lamellar armor 2 via a driver 35 and a connecting part 34 (FIG. 4). If the shaft of the electric motor 22, whose direction of rotation is reversible, rotates clockwise in the figure, the concentric drive rollers 26, 28 are also rotated clockwise. Accordingly, the attached to the V-belt 30
  • the motor 22 is fastened vertically in the interior of the winding 13 to a vertically supported bearing plate 36 and protrudes the drive belt 24 and the drive rollers 26, 28 with the V-belt 30 in connection.
  • Upper guide profiles 38 are further fastened to the bearing plate 3b, which have a course corresponding to the spiral course of the lower guide profiles 14 and connect to a profile bar 39 (FIG. 4) arranged in the region of the gate opening 6.
  • the profile bar 39 (FIG. 4) arranged in the region of the gate opening 6.
  • guide rollers 40 arranged with a vertical axis and support rollers 42 arranged with a horizontal axis.
  • the guide rollers 40 and the support rollers 42 are attached to the connecting parts 34.
  • the upper edges of the slats 8 are attached.
  • the lower area of the slats 8 is covered by the closed, hinged box 11.
  • the driver 33 is fastened with its upper end to the V-belt 30 guided around a deflection roller 44 and attached with its lower end to the connecting part 34 a lamella 8 of the lamellar armor 3 is arranged.
  • a connection corresponding to this connection between the V-belt 30 and a lamella 8 of the lamellar armor 3 is brought about via the driver 33 'between the V-belt 30 and the other lamellar armor 2' which is hidden in the figure.
  • a cover 4b protects the drive and guidance of the lamellar armor 2, 2 'against undesired ingress of dirt and the like.
  • the detail V according to FIG. 1 shown enlarged in FIG. 1 shows lamellae 8, the adjacent lateral edge regions of which are connected to one another via sealing tapes 48 fastened to them.
  • the lower edges of the sealing tapes 48 run flush with the lower edges of connecting parts 50, that is to say they cover the upper edge of the continuous closing tape 20, so that no gap remains in the areas between adjacent slats 8 and a very tight closing of the gate opening 6, which prevents drafts and dust from entering is made possible.
  • a guide rail 52 which is essentially U-shaped is provided for the guide rollers 16.
  • the guide rail 52 is closed off by two cover rails 54, 54 ', which leave a narrow slot 56 free.

  • the spring element 58 is pushed by the guide rollers 16 to the inside of the guide rail 52, which is on the left of the figure, so that it assumes the position shown by releasing the slot 56. If the slats 6 of the slat armor 2 and thus the guide rollers 16 are withdrawn from the guide rail 52 to open the door, the spring element 58 assumes the position shown in FIG. 6b and closes the slot 56. The sliding movement of the spring element 58 is thereby facilitated, that the same.
  • the spring element 58 has a crank 62 in the region of its free end, which engages in the slot 56 when the gate is opened and forms a continuous surface with the upper surfaces of the cover rails 54, 54 'almost seamlessly, so that accumulation of dirt on the upper surface of the crank 62 is largely avoided.
