Definitions

  • the invention relates to a roller door, in particular a high-speed roller door, according to the preamble of claim 1.
  • Rolling doors with a flexible curtain made of PVC o. The like. Have long been used in practice. They have proven to be excellent to wind-tight completion, for. to produce between individual rooms in larger halls or the like. Compared to door arrangements with door leaves made of lamellae or sections, such roller doors have the advantage that they have a lower weight. They can therefore be operated at very high speeds.
  • roller doors usually have a winding shaft on which the curtain is wound up when opening.
  • lateral edges of the curtain are guided in associated lateral guides to produce here also a substantially windproof closure.
  • conventional roller doors are usually provided with a rigid end plate at the leading edge of the door leaf. This is usually designed as a metal profile and stiffens the curtain transverse to the direction of movement of the door leaf.
  • this end plate extends into the area of the lateral guides and has a predetermined weight, so that the curtain is stretched in the direction of movement over its entire width between the end element on the one hand and the winding shaft on the other hand.
  • the end plate is guided on both sides by means of slides in the lateral guides that it is trapped in the direction of movement of the door leaf, but can pivot transversely to this.
  • the end plate is here on both sides in such a way connected with tension cables, that even with a swinging of the end plate a train connection between the door drive and the end plate is maintained.
  • the tension cables are here resiliently biased, whereby a corresponding movement path is made possible. They support a provision of the end plate in its normal position. As far as there is no collision case, these tensioning cables serve both as in the already explained construction to tension the curtain in the direction of movement of the door leaf.
  • Another systematic approach for a collision protection device on a roller door is from the EP 2 402 543 A2 or the DE 20 2010 007 949 U1 known.
  • This roller shutter whose curtain is motor-driven on a winding shaft in a conventional manner or unwound, has no end plate of a rigid metal profile or the like, but a closing element, which is elastic in itself and thus in the plane of the curtain and transverse thereto deformable executed. This makes it possible to avoid obstacles and thus avoid damage.
  • the closing element has a joint body and / or a chain, which can also be prestressed by means of an elastic traction means. In this case, the joint body or the chain on a certain weight, so that the closing element automatically assumes a stretched position under the influence of gravity.
  • a traction means such as a rubber cord or a rubber band is used, whereby at the same time the door curtain is stretched in the direction of movement of the door leaf.
  • the weight of the joint body or the chain on the end element by gravity acts supportive.
  • elastic traction means promote the closing process.
  • one of the traction means also serves as an indicator for the presence of a collision case in that it cooperates with a sensor which detects the position of the traction means in the region of the terminating element. If there is a collision case, the orientation of the traction means changes, so that here the sensor can deliver a corresponding signal.
  • a disadvantage of the roller door according to the EP 2 402 543 A2 is, however, that the joint body or the chain must have a very considerable weight so that they can fulfill the desired function for tensioning the curtain or to support the closing movement of the same. Due to the mass thus given these elements continue to pose a risk to the leading edge of the roll-up doors persons or objects, so that it still can cause injury or damage. Since the closing element is not rigid here, there is also an increased risk that it will tilt in the course of the closing operation of the door leaf.
  • This known roller shutter is driven in a conventional manner by the operation of the winding shaft, on which the curtain is wound up when the roller shutter is opened.
  • a ballast tube is also arranged at the foremost end of the leading edge, which is filled with a deformable material such as sand.
  • This ballast tube provides a weight at the bottom of the lifting gate shown, which not only supports the closing process itself, but also biases the curtain in the vertical direction. However, this additional weight limits the opening speed.
  • the present invention is based on EP 0 675 261 A1 as the closest prior art.
  • the invention is therefore based on the object to improve a generic roller door such that this represents a reduced risk for persons or objects in the collision trap with high reliability during operation.
  • the driving force for closing the door opening at such a roller shutter although it is formed with a flexible curtain with a Behangabschnitt and an elastic, so in itself freely elastically deformable end element, can also act on the closing element.
  • the driving force for closing the door opening at such a roller shutter although it is formed with a flexible curtain with a Behangabschnitt and an elastic, so in itself freely elastically deformable end element, can also act on the closing element.
  • the risk of damage to goods and / or implements in the event of a collision decreases.
  • the end element is less susceptible to damage even then.
  • the pulling force component for closing the door leaf provided on the roller door according to the invention thus represents an active drive by means of which this movement can be controlled more precisely than via the passively acting systems with the weight in the prior art.
  • roller shutter according to the invention is then independent of a specific orientation, so that it need not necessarily be arranged as a lifting door with an upright orientation as in the prior art, but also, for example, allows an oblique or horizontal termination between rooms or different areas.
  • Another advantage of the rolling door according to the invention is that it can be used with high reliability and is characterized by longevity.
  • roller door according to the invention can in this case have a surprisingly simple construction. It is thus hardly prone to failure and also inexpensive to provide. In many applications, a waiver of additional safety devices such as Torlichtgittersysteme or the like is also possible.
  • the drive of the roller door in the region of the lateral guides each have a pulling member which transmits the driving force to the closing element of the door leaf.
  • This allows a particularly simple structural design of the drive system and is characterized by a high reliability.
  • Such traction devices have long been used on roller doors and have proven very successful.
  • the tension member is formed in two parts with a drive part and a tensile force transmission part, wherein the drive part is designed to transmit the driving force as an endless element, and wherein the Traction transmission part transmits the transmitted with the drive part driving force to the end element of the door leaf.
  • the drive part is designed to transmit the driving force as an endless element
  • the Traction transmission part transmits the transmitted with the drive part driving force to the end element of the door leaf.
  • the drive part of the tension member may be formed at least in a partial section as a toothed belt, chain or the like. With such elements, a positive connection for the tension member can be provided, whereby a particularly reliable operation of the roll-up door is made possible.
  • the tensile force transmission part of the tension member is designed as a pull rope. As a result, a transfer of the tensile forces can be permanently achieved in a proven manner.
  • the construction of the roller door according to the invention is further simplified. Then you can dispense with a separately designed counterbalance regardless of the drive.
  • the roller shutter according to the invention then receives a particularly compact and simple design.
  • the drive has a pulley arrangement over which the tension member is guided.
  • the drive arrangement can be advantageously controlled so that with a small movement path on the drive element such as a pinion on the engine a certain Torblatthog is achieved.
  • this also allows the acting forces to be set advantageously.
  • the closing element of the door leaf is coupled on both sides with a carriage which moves together with the closing element guided in the lateral guides and carries a deflection device, via which the pulling member in each case from the lateral guides to the end element is deflected out.
  • the tension member is aligned with respect to the end element, that it provides a particularly suitable division of the driving force in the lateral force component or the tensile force component.
  • the angle with which the pulling member acts on the closing element, regardless of the closed state of the door leaf is always the same by the closing element with moving carriage.
  • the same tensile component is accordingly applied to the closing element of the door leaf over the entire closing process.
  • the same lateral force component is provided for tensioning the closure member.
  • the carriages are guided by means of rollers in the lateral guides, they can be guided with low friction and therefore have a high life expectancy.
  • the reliability of the roller door according to the invention further increases.
  • the closing element of the door leaf is detachably coupled to the respective slide on both sides in such a way that it can be deflected out of the door leaf plane in the event of a collision.
  • the roller door according to the invention provides a kind of active collision protection device and not only provides a passive protection device by the elastically formed end element. The risk of damage to the rolling door according to the invention or of affected objects, etc. in the course of a collision is thereby significantly reduced.
  • the two-sided tension members are still connected to the end element of the door leaf, this is not fully released and also traceable by means of the traction elements in its normal position.
  • the slides are each connected via a latching connection with side edge elements of the closure element.
  • a locking connection can be canceled in the event of a collision non-destructive and then re-manufacture. This further reduces the risk of damage to the terminating element in the event of a collision.
  • a latching connection is a reliable coupling way, which permanently enables trouble-free normal operation of the rolling door according to the invention.
  • the latching connection is configured such that the side edge elements of the closure element automatically engage in the carriage when the closing element is deflected in the course of a closing movement of the door leaf. This is possible in a very short time and with little effort a restoration of the normal state of the rolling door according to the invention after a collision trap.
  • it is provided for the first time within the scope of the invention to perform this return to the normal position not in the course of an opening movement of the door leaf, but a closing movement.
  • At least one carriage has a sensor device which detects the coupling state between the carriage and the terminating element. In this way, a particularly reliable detection of a collision case is possible. It is irrelevant whether the coupling state has been canceled by a lateral emergence of the closure element from the Torblattebene or by an elastic deformation of the closing element in the Torblattebene.
  • the sensor device By the sensor device, a corresponding fault routine can be promptly and reliably initiated. This is usually at least that the roller door opens and thus provides a greater clearance height in the door opening.
  • a first embodiment of a roll-up door 100 is shown.
  • the leading edge is the edge region or the edge on the hanging section 111, which lies in front when closing the door leaf 110 in the direction of movement.
  • the roller door 100 which is designed here as a lifting door, further comprises a winding shaft 120, on which the door leaf 110 is wound when opening the roll-up door 100.
  • the roller door 100 includes lateral guides 130, one of which in Fig. 2 is shown, and in which lateral edges of the door leaf 110 are received.
  • the roller door 100 also includes a drive 140, which generates a driving force for driving the door leaf 110.
  • the Fig. 2 As can be seen from this, it has a Zargenkasten 131 which forms an inlet funnel 132 in the region of the associated lateral edge of the door leaf 110, which opens into a guide gap 133.
  • the inlet funnel 132 has an opening angle of approximately 100 °.
  • the guide gap 133 is selected so that the door leaf 110 can be guided with play therein.
  • the drive 140 has a motor 141, which is coupled via a transmission gear 142 with the winding shaft 120.
  • the motor 141 By the motor 141, the winding shaft 120 is set in rotary motion.
  • the door leaf 110 is wound onto the winding shaft 120 or unwound therefrom.
  • a drive pinion 143 which drives a pulling member 144, is also arranged laterally outside the winding region for the hanging section 111.
  • This pulling member 144 serves to apply a driving force for closing the door leaf 110 on the closing element 112.
  • a transverse force component is applied to the closing element 112 with which it is tensioned transversely between the two lateral guides 130.
  • the closing element 112. is not configured as a rigid component, but designed to be elastic. It is therefore freely deformable per se both in the plane of the curtain and transversely thereto and can accordingly adapt to obstacles or elastically deform around them without damaging or permanent changes in shape occurring on the closing element 112.
  • the closing element 112 is formed by a pocket formed of a flexible material at the leading edge, such as the hanging material, into which a lighter, more flexible and cushioning body, such as e.g. Foam or the like is inserted. Without the transverse force components applied by the pulling member 144 on both sides, the closing element 112 would be flexible or deformable even at low lateral forces and could not produce a reliable closure in the bottom area.
  • the tension member 144 has a toothed belt 145, which interacts positively with the drive pinion 143.
  • the pulling member 144 has a pull cable 146, which receives the driving force of the toothed belt 145 and further transmits.
  • a weight 147 is provided, on which on one side of the toothed belt 145 and on the other side of the pull cable 146th is attached.
  • the drive 140 further includes a tension spring 148, which is fixed on the bottom side and cooperates with the pull cable 146.
  • the drive 140 still has a buffer container 149 for the toothed belt 145.
  • the toothed belt 145 is fixed in this buffer container 149 with the interposition of a spring arrangement, not shown.
  • the buffer container 149 is also adapted to accommodate a loose of the toothed belt 145 when closing the door leaf 110 in a certain frame; at a greater length of the tension-free end of the toothed belt 145, the supernatant simply overhangs laterally.
  • the toothed belt 145 runs over the drive pinion 143 until the door leaf 110 has reached its open position. In order to mitigate here the stopping of the door leaf 110 at the upper end of the door opening, dampens the already mentioned, not shown spring in the buffer tank 149 the last portion of the movement path of the toothed belt 145th
  • the drive 140 further includes a pulley assembly 150, over which the pull cable 146 runs.
  • the traction cable 146 is first guided over a deflection roller 151 at the free end of the tension spring 148, as in particular from Fig. 1 is recognizable.
  • the pull cable 146 is then guided over a further deflection roller 152 on the weight 147.

  • the weight 147 is pulled upward in the direction of the winding shaft 120 via the toothed belt 145.
  • the lots on the toothed belt 145 is then moved into the buffer container 149 or suspended laterally next to it.
  • the door leaf-side end of the pull cable 146 engages in an ever smaller angle relative to the footprint of the roll-up door 100 on the closing element 112, as in particular Fig. 4 is apparent. Accordingly, an ever-increasing lateral force component acts on the side edge elements 113 of the closing element 112.
  • the pulling cable 146 is approximately at an angle of 40 ° -50 ° to the associated side edge element 113 on the closing element 112. The transverse force component present thereby is sufficient to to properly tension the end member 112 in the transverse direction between the side guides 130.
  • the weight 147 When the door leaf 110 is completely closed, the weight 147 reaches its highest position above the footprint of the roller shutter 100. Furthermore, the tension spring 148 is also maximally tensioned in this state. This ensures that the door leaf 110 opens in case of emergency, for example, in case of power failure automatically.
  • the weight 147 and the tension spring 148 thus represent a counterweight device which actively supports an opening movement of the door leaf 110.
  • the motor 141 is driven in the opposite direction, so that the hanging section 111 is wound on the winding shaft 112.
  • the leading edge of the door leaf 110 is gradually released via the toothed belt 145 and the traction cable 146, so that a controlled opening movement of the door leaf 110 and a wrinkle-free winding of the same on the winding shaft 120 is made possible.
  • the loose in the toothed belt 145 is thereby pulled out of the buffer container 149 until it is resiliently fastened in the buffer container 149.
  • This spring force prevents a hard stopping of the door leaf 110 in the course of the winding process. As a result, damage to the door panel 110 can be reliably avoided.
  • the weight 147 is then in its lowest, the footprint closest standing position and the tension spring 148 is largely relaxed.
  • the door leaf 110 of the roll-up door 100 is thus actively pulled by the pulling action on the pull cable 146 of the pulling member 144 in its closed position, the pull cable 146 for this purpose provides a directed substantially in the direction of movement of the door leaf tension component. At the same time, however, the pull cable 146 also provides a lateral force component on the end member 112 by which it is tensioned transversely between the side guides 130.
  • the elastically formed closing element 112 is able to deform, despite the tension caused by the transverse force components, and thus to avoid damage to the closing element 112 or the impacting object.
  • the tension spring 148 releases a certain length of pull cable 146 in a predetermined manner in accordance with the acting force in a predetermined manner, so that the closure element 112 can execute a corresponding deformation.
  • the force acting on the closing element 112 in the event of such a collision is thus resiliently received by the tension spring 148 via the pulley arrangement.
  • tension spring 148 acts in the course of the opening or closing movement also compensating in terms of the one hand by the winding shaft 120 and on the other hand forces applied by the pulling member 144 on the door leaf 110.

Furthermore, the roller door 200 includes a winding shaft 220 and side guides 230, of which only one is indicated in the figures for the purpose of illustration. Finally, the roller shutter 200 also includes a drive 240 for providing the driving force for the operation of the door leaf 210.
  • each of the lateral guides 230 a Zargenkasten 231 on.
  • This contains an inlet funnel 232, which opens into a guide gap 233, in which the door leaf 210 is received with play.
  • the drive 240 includes a motor 241 and a transmission gear 242, in particular in the Fig. 5b and 6b is recognizable. Thus, the winding shaft 220 is driven. On this also a drive pinion 243 is arranged, which cooperates with a pulling member 244.
  • the tension member 244 is here in this embodiment designed in several parts and has a drive part and a tensile force transmission part.
  • the drive member includes a timing belt 245 and a drive cable 246a. These are formed in this embodiment as an endless element, that is arranged to each other so that they can transmit a traction circumferentially.
  • the traction transfer member includes a traction cable 246 which ultimately transmits the traction to side edge members 213 of the end member 212.
  • the weight 247 is received between one end of the toothed belt 245 and the drive cable 246a.
  • the drive cable 246a is finally deflected over a bottom-mounted pulley 254 and guided to a stop 255. At this stop 255, the other end of the toothed belt 245 is attached.
  • the pull cable 246 is also attached to the weight 247. It is also guided via a pulley arrangement 250 to the side edge element 213 on the closing element 212.
  • the pulley arrangement 250 for this purpose includes a deflection roller 251 on the tension spring 248 and a further deflection roller 252 on the weight 247 similar to the configuration in the first embodiment.
  • the pull cable 246 is then deflected over a bottom-mounted deflection roller 253 such that it can finally engage the side edge elements 213 of the closure element 212.
  • the pull cable 246 extends on both sides via a slide 260, which is guided in the region of the associated lateral guide 230.
  • the carriage 260 has for this purpose rollers 261, by means of which it is supported adjacent to the guide gap 233 within the frame box 231 and is moved in a rolling motion.
  • the carriage 260 further comprises a deflection section 262, here in the form of a roller, by means of which the traction cable 246 is deflected in such a way that it under a certain, in all closed positions of the door leaf 210 same angle on the side edge element 213 of the closing element 212 engages.
  • the carriage 260 is moved with the closing element 212 with, when the door leaf 210 is moved.
  • each side edge element 213 of the end element 212 has a latching hook 214, which engages positively in a latching nose 263 on the slide 260. This connection is solvable in the event of a collision.
  • a sensor element 265 is further arranged on the carriage 260. This cooperates with a sensor part 215 on a side edge element 213. If the relative position of the sensor part 215 changes relative to the sensor element 265, it is possible to detect a swiveling of the closure element 212 out of the door leaf plane and / or a deformation of the closure element 212 in the door leaf plane and initiate a fault routine or the like.
  • the sensor consisting of the sensor element 265 and the sensor part 215, is designed here as a magnetic switch.
  • the operation of the roll-up door 200 is basically similar to that of the roll-up door 100 according to the first embodiment.
  • a drive force is also exerted on the drive pinion 243 by the motor 241 via the transmission gear 242 such that the toothed belt 245 pulls the weight 247 in the direction of the winding shaft 220.
  • the drive cable 246a is tightened, which in turn pulls the stopper 255 down and thus keeps it by the peripheral configuration with the timing belt 245 this under tension.
  • the door leaf 210 is released from the winding shaft 220.
  • the motor 241 is driven in the opposite direction, so that the door leaf 210 is wound onto the winding shaft 220.
  • the toothed belt 245 is driven in a direction in which the weight 247 can be lowered toward the footprint of the roll-up door 200. Accordingly, also relaxes the tension spring 248, and the pulley assembly 250 is the Glasseil 246 such a lot given that this allows the pulling up of the leading edge of the door leaf 210.
  • the stopper 255 meets a corresponding frame-side counterpart, thus preventing a winding of the door leaf 210 beyond a predetermined point.
  • the stopper 255 is in this case resiliently biased, so that there is no abrupt stopping of the door leaf here.
  • the deflection section 262 on the respective carriage 260 causes the pull cable 246 to always engage at the same angle on the side edge element 213 of the closure element 212.
  • the ratio of the size of the transverse force component to the tensile force component therefore remains the same in all closed positions of the door leaf 210.
  • the size of the transverse force component and the tensile component increases in each case with progressive approach to the closed position of the door leaf 210 due to the increasing bias of the tension spring 248.
  • the leading edge of the door leaf 210 with the closing element 212 disposed thereon is stretched in all positions of the door leaf 210.
  • the configuration of the rolling gate 200 also allows emergency opening in the event that, for example, the power supply fails. Then, the door leaf 210 opens by itself due to the mass of the weight 247 and the bias of the tension spring 248th
  • the roller door 200 allows a center section of the closure element 212 to be pivoted out of the door leaf plane in the event of a collision.
  • the in Fig. 8 shown latching connection between the side edge elements 213 and the respectively associated carriage 260 repealed.
  • the latching hook 214 is disengaged from the locking lug 263.
  • This state is in Fig. 9 shown.
  • the connection of the pull cord 246 and the end member 212 is maintained. This facilitates the restoration of the latching connection between the end element 212 and the slide 260. In the case of the roller door 200, this takes place during the closing of the door leaf 210.
  • the locking lug 263 on the carriage 260 has a shape which is complementary to the inlet funnel 232 of the lateral guides 230 configured.
  • the carriage 260 can be particularly well on the associated Zargenkasten 231 lead.
  • the latching hook 214 on the side edge element 213 has on the side facing thereto a corresponding configuration matching the inlet funnel 232, so that thereby the threading of the closure element 212 is facilitated in the event of a collision.
  • the inlet funnel 232, the snap hook 214 when reinserted into the latch 263 side such that the restoration of this locking connection is particularly reliable possible.
  • a quick return of the roller door 200 is possible in its normal operating state after a collision case.
  • roller door 200 in the figures is explained in detail only with reference to a side edge area. It is understood that the configuration in the region of the other lateral guide is substantially mirror-inverted.
  • the invention allows, in addition to the illustrated embodiments, further design approaches.
  • the weight 147 or 247 can be dispensed with. This is particularly the case when the tension spring 148 or 248 provides a sufficient restoring force for an emergency opening of the roller door 100 or 200, or such emergency opening function is not required.
  • the tension member 144 or 244 may also have a tension band instead of a toothed belt or a chain, which may be e.g. is wound in the region of the winding shaft 120 and 220, respectively.
  • the closing element of the door leaf on both sides can also be detachably coupled to the respective slide such that it emerges from this connection in the event of a collision, without leaving the door leaf level. This is the case, for example, when the door leaf is lowered to an obstacle when closing.
  • the end element in the Torblattebene solves the connection to the respective carriage.
  • connection between the carriage 260 and the end element 212 can also be done in a different way than via a latching connection. So here, for example, a cohesion can be produced by magnetic forces. Alternatively, it is also possible to produce a correspondingly predetermined releasable connection by means of shear pins or the like.
  • the restoration of the connection between the closing element 212 and the associated carriage with a swung-out closing element 212 can also take place in another way and elsewhere in the path of movement of the door leaf 210. For example, this is also possible at the upper end of the lateral guides 230 adjacent to the winding shaft.
  • the sensor device with the sensor element 265 and the sensor part 215 can also be dispensed with if such an automatic detection of a collision case does not appear necessary.
  • any other type of sensor can be used to detect a collision case.
  • the deflection section 262 can also be designed in the form of a sliding guide or the like instead of the illustrated roller.
  • the two illustrated embodiments each show roller doors in the form of lifting gates.
  • other orientations of the door leaf are possible, such as inclined or horizontally oriented door leaves.
