Definitions

  • the invention relates to a roller door with the features of the preamble of claim 1.
  • Roller shutters of this type are known - DE-GM 82 06 622 - whereby it is difficult to keep thin and light door leaf curtains in the closed state taut and tight even under the influence of wind.
  • the invention has for its object to provide a roller door of the type in question, the curtain is kept as tight as possible in the closed position, and in addition a space-saving and simple to assemble should be given.
  • the roller shutter shown has no weight compensation spring. Such is often provided inside the winding roller 2, which complicates maintenance. There are other solutions with external counterbalance springs.
  • the gate according to the invention can also be provided with such a weight compensation spring device.
  • the mass of the curtain i.e. the door leaf weight is relatively low, so that a weight balance seems unnecessary.
  • Weight differences between the rolled and the rolled curtain, which act as torque on the axis of the winding roller are - like the acceleration forces - absorbed by the drive, in particular designed as an electric motor, which is common to the winding roller 2 and the conical rope drums 4 Wave 3 attacks.
  • the taper of the cable drum 4 is chosen so that when the curtain 1 rolls into the door leaf closing position and thus in diameter decreasing curtain roll 11, the pull rope 5 is wound, but in the direction of a decreasing diameter in accordance with the decreasing curtain diameter.
  • the tension spring 6 acting on the tension cable 6 is therefore not exposed to any change in length due to the curtain movement itself, so it remains during operation in the same more or less pretensioned working position, in which the curtain is kept so tight that it is faultless in its lateral guides running.
  • the spring is therefore initially only used to compensate for differences in dimensions, such as those that can occur in particular as a result of temperature changes.
  • the two conical cable drums 4 are fixed on the drive shaft 3 with the aid of ratchet wheel and ratchet, the ratchet wheel being rotatably mounted on the shaft 3 and the pawl on an end face of the respective conical cable drum 4.
  • the pawl works in the engagement direction so that in the course of a rotary movement of the cable drum 4 around the shaft 3 and against the latching direction of the pawl, the pull cable 5 is wound onto the cable drum. In this way, the pulling rope 5 can be wound onto the rope drum 4 against the force of the coil tension spring 10 arranged in the lower frame area via the pulley 7, 8.
  • the conical rope drum has the following special feature, which is particularly, if not exclusively, important in connection with the thin, low-weight curtains of roller doors in question: Shortly before the door leaf arrives in the closed position, ie approximately a distance which corresponds to the length of a reel, in the present example approximately 70 cm, the traction cable 5 arrives at the point with the smallest drum diameter in the course of the spiral cable receiving groove of the drum. The rope is thus wound in the course of the closing process of the curtain from one end, for example, seen from the outside of the curtain, with a large diameter of the cable drum in a position with a decreasing diameter, following the guidance of the correspondingly shaped groove in the axial direction of the roll.
  • the traction cable 5 is wound onto a partial area of the cable drum 4, which increases again with regard to the drum diameter in the course of the winding process and also continues the guide groove in this area.
  • the result is that the cable tries to shorten and thus exerts an increasing load on the tension spring 10.
  • a corresponding tensile force is applied to the curtain 1, so that in the closed position it is stretched taut between the ropes and the winding roller 2, such that the curtain is only slightly warped even under strong wind loads, despite the thin design.
  • the cable drum corresponding to the above tension conditions thus has a double-conical shape, the location of the smallest diameter being located off-center between the end faces of the drum, each with an increased diameter.
  • a cable drum shape is not only important for very thin curtains, it can in principle be used for a special tensile load on a roller shutter door in the closed position.
  • a special fixing of the curtain 1 on the winding roller 2 is not necessary because the curtain is only unwound by the winding roller 2 up to about one and a quarter turns. It is therefore sufficient to have the end of the curtain 1 close to the roller on the upper winding roller to fix the surface at the appropriate place, for example to glue it on. For normal operation, the remaining wrap angle of the curtain on the roller is large enough to ensure a non-slip attack between the curtain and the roller, even when viewed from the closed position of the curtain.
  • the relatively thin curtain in question is wound around a roller, the drive shaft 3 of which is rigidly mounted with respect to its spatial position or spacing from the lintel of the opening to be closed. There is therefore no positively controlled displacement movement of the drive shaft 3 depending on the winding condition of the winding roller 2, as can be provided in the case of thicker curtains or lamella door leaves in order to be able to introduce the draining curtain from the curtain winding into the lateral guides as smoothly and as freely as possible.
  • the curtain 1 is steered into its closing plane or its lateral guides with the aid of a support roller 14, the special structure of which is described below:
  • the support roller 14 is provided with a hose-like structure 15, in particular a textile, such as fabric, felt or the like, which is pushed onto the outer surface of a tubular fixed support 16 and is rotatably held thereon about the latter.
  • the hose-like structure 15 can extend over the entire width of the curtain or can be designed and arranged in several parts limited to partial width regions of the curtain.
  • the curtain engages on the outer surface of this tubular sliding textile or the like. The movement of the curtain entrains the hose or structure and rotates it relative to the carrier. Measures to achieve particularly good sliding properties can be taken between the tubular structure and the carrier, this can be achieved by appropriate pairing of materials or by the arrangement of a corresponding one low-friction intermediate layer can be achieved.
  • Such a support or guide roller 14 can be provided between the lintel and the curtain 1, but it can also act on the surface of the curtain 1 facing the interior of the room or can additionally be arranged in this direction, so that a pair of such guide rollers or hose-like structure lead the curtain 1 between them.
  • the guiding properties of such a support roller 14 are so good that even large deflections of the curtain course seen in the direction of movement can be handled effortlessly and with little friction and with wear.
  • the carrier 16 for receiving the tubular structure 15 is fixed and accordingly has only a partial area on which the textile structure must be supported.
  • the cross-sectional dimension of the carrier can accordingly be limited to such a curved wing area. So it does not have to be a pipe, a support with a C-shaped cross section or a similar design can also be used.
  • the radius of curvature of the wing area is primarily determined by the deformability of the curtain.
  • the tubular structure is more flexible than the curtain, so it can undergo greater curvatures, so that one can work with correspondingly narrower "support rollers", the supports of which are significantly narrower than twice the diameter of the radius of curvature and the tube guided on the wing in the area. and the run-up area of the wing passes through a bend that is narrower than this.
  • a special feature of this support roller 14 with the rotating hose is that the moving mass is very small because the hose only has to have a small wall thickness and is the only part of this support device that rotates. Bearing, balancing and, in so far, also abrasion problems, which would be comparable to those of rolling bodies rotatably mounted about relatively thin axes, do not occur.
  • Such a radially projecting flange can be formed, for example, by a so-called collar bushing which has a cylindrical part, onto which the hose is pushed, and which is provided with a radially projecting part, which forms the actual end face or sliding surface.
  • a so-called collar bushing which has a cylindrical part, onto which the hose is pushed, and which is provided with a radially projecting part, which forms the actual end face or sliding surface.
  • the carrier in the wing area or continuously spherical or imitate such a crown by providing some webs on the carrier towards the axial center with increasing diameter and the like and more.
  • the measure to be taken largely depends on the consistency of the hose material; a rigid hose can guide itself, while a hose that tends to bulge or compress in the axial direction may have to be seized separately in the end region (collar bushing).
  • the traction cables must be wound onto the conical cable drums 4 following the course of the groove.
  • the bottle in the frame side area 7, 8 and tension spring 10 are accommodated in a cover 17 and / or if there is a corresponding run-up distance due to the arrangement of a support roller 14 below the winding roller 2 or the cable drums 4, it may be advisable or necessary below the support roller in each side area of the frame frame to arrange a rope pulley, which takes over the guidance of the pull rope 5 from the longitudinal course parallel to the side frame to the groove guide on the associated conical rope drum 4, accordingly, both with regard to the rope deflection around the shaft 3 and in the axial direction of the shaft, distributing around the rope to distribute the cable drum, provided with a corresponding helical groove, with the appropriate axis offset.
  • the fastening of the traction cable or the drum-side traction cable end to the cable drum can be carried out in a simple manner from an assembly point of view, similar to that described in connection with the holding of the curtain on the winding roller 2. If you make sure that one turn of the pull rope remains on the rope drum, the friction is sufficient to hold the rope on the drum without any special definition. For example, you can simply put the rope end through a radially directed hole in the beginning of the spiral groove, which makes assembly very easy.
  • bracket can also be used between the pull rope and the rope drum in a different context than in the roller shutter structure described above with thin curtains, so also in the case of overhead sectional doors whose bottom edge of the door is held with ropes that run up and down on rope drums.
  • the above-described support body is not limited to use with thin-walled curtains of roller doors, but can generally lead roller door leaves, especially those that consist of a thicker and / or stiffer, in particular multi-layered curtain.
  • the particularly good guiding properties of such support rollers can lead to the fact that there is no need to adjust the winding roller shaft as a function of the unrolled door leaf length for introduction into the door leaf guides.
  • the lower edge of the door leaf is formed by a curtain end rail 13, which consists of at least two hollow chamber profiles 18 and 19, one of which is designed as a base body 18, in which the other, serving as a cover part 19 profile can be hung , for which purpose a correspondingly designed cross-sectionally shaped cross-section 20 on the cover part 19 engages over a web 21 which engages in the hook-shaped recess and is provided on the base body 18.
  • a kind of hinge movement about an axis running in the width direction of the curtain is possible between the two profile parts 18 and 19.
  • the cover part 19 a cavity 22 with a rectangular cross section, in which screws (not shown) spaced apart in the width direction of the curtain 1 are received, which engage through the curtain 1 and into a profile section 23 of the base body 18 and are screwed therein.
  • the end profile of the curtain is provided with a rubber sealing bead protruding downwards and bears a yellow-black warning marking 24 on the front of the cover part 19 in the usual way.
