Definitions

  • the present invention relates to a device for installing a winding shaft of a vertically opening roller door, with a bearing block arranged on the winding shaft and a bearing block holder which is arranged on a frame of the roller door.
  • the present invention relates to a method for installing a winding shaft of a vertically opening roller shutter, and to such a roller shutter.
  • the first step in installing a vertically opening roller shutter is to set up the frames. These are the vertical parts of the goal frame, which include the guide rails for the goal hanging. Depending on the installation situation, the frames are either mounted on or in a building opening, or they are attached to a floor surface and protrude vertically without any additional connection points.
  • the cross connection is then installed, whereby a profile is usually installed to connect the upper ends of the previously constructed gate frames. If the roller shutter is used to close a building opening, you can also use the option of attaching the cross connection to building elements.
  • the winding shaft is installed, usually with the door curtain wound up. This is done by fixing the bearing blocks pre-assembled on the winding shaft to the gate frames, for which screws are usually used.
  • panels are attached to the gate frames and/or the cross connection. On the one hand, these serve to protect against the entry of dirt and, on the other hand, to prevent improper manipulation of the roller shutter and its components.
  • the most complex and therefore critical step in installing roller shutters is the installation of the winding shaft. Since the door curtain is often already wound onto the winding shaft, it can weigh up to several hundred kilograms. For this reason, the rough placement of the winding shaft is usually done using a forklift. The exact alignment and fixation using screws is then carried out manually, although this step is not only made more difficult by working at height, but often also has considerable potential for accidents. For this reason, the possibility of fine adjustment, which is often provided by the elongated holes in the frame, is usually not taken into account.
  • the present invention is therefore based on the object of describing a device which simplifies the installation of a winding shaft of a vertically opening roller shutter.
  • a roller shutter with such a device and a method for installing a winding shaft of a vertically opening roller shutter are further aspects of the invention.
  • a device has a bearing block and a bearing block receptacle.
  • the bearing block is already arranged or pre-assembled on the winding shaft to be installed. This can be an axially closed bearing block, if it is mounted on an axial end of the winding shaft, or an axially continuous bearing block, if further components, such as a drive motor, are on the side of the bearing block facing away from the door curtain Winding shaft can be arranged.
  • the bearing block has a rectangular shape, at least in sections, when viewed in the axial direction of the winding shaft. Its depth is chosen such that a bearing that is sufficiently dimensioned for the forces introduced by the roller shutter can be accommodated in it.
  • the bearing block holder is the counterpart to the bearing block described above. It essentially consists of three sections.
  • the fastening section rests on the side of a gate frame facing the gate curtain, which in the context of the present application includes both the vertical guide and the head plate located above it.
  • the fastening section is fastened to the gate frame, i.e. the vertical guide and/or the head plate, using a suitable fixing means. This can be done either via releasable connecting means, such as screws, or via an inseparable connection, such as a welded connection.
  • the sliding section of the bearing block holder extends at right angles away from the fastening section and thus in the direction of the door curtain. According to the name, this is the section over which the bearing block slides into its final position in a manner described later.
  • the sliding section is arranged inclined.
  • the end stop is located at the deeper end of this inclination. Just like the sliding section, this extends in the direction of the goal curtain, vertically away from the top plate of the goal frame. Together with the sliding section, the end stop describes an angle which is less than 90° in the initial state, i.e. before the winding shaft is installed.
  • the flexibility of the transition area between the sliding section and the end stop is selected such that this angle is increased by the force exerted by the weight of the winding shaft with the curtain wound up.
  • the geometry of the sliding section and end stop essentially corresponds to the shape of the bearing block, which defines an end position for the latter.
  • the connection between the winding shaft and the bearing block also defines the closing level of the door curtain via the design and positioning of the bearing block holder.
  • the inclination of the sliding section of the bearing block receptacle is selected such that the bearing block arranged on the winding shaft can slide down the sliding section and assume its final position solely by gravity. It depends largely on which material pairing is present in the contact area between the bearing block holder and the bearing block. If the corresponding coefficient of static and/or dynamic friction is higher, the inclination is chosen to be somewhat steeper, whereas if the coefficient of static and/or dynamic friction is lower, a flatter inclination is provided.
  • a provision is provided for fixing the bearing block in the end position of the bearing block receptacle.
  • a screw connection for example, is suitable as such a precaution, but other suitable fixations are also conceivable.
  • two screws for fastening the bearing block are provided per bearing block receptacle. This represents a good compromise between additional installation effort and improved security.
  • a roller shutter according to the invention includes a device in one of the embodiments described above. Compared to roller shutters known from the prior art, this roller shutter is significantly easier to install. On the one hand, this significantly shortens the time required for assembly. On the other hand, the safety of the people carrying out the assembly is also improved, since the number and complexity of the work steps to be carried out at height is reduced.
  • the invention further includes a method for installing a winding shaft of a vertically opening roller shutter.
  • a bearing block is mounted on a winding shaft.
  • an axially closed bearing block comes into consideration, if this is intended for mounting on an axial end of the winding shaft.
  • this can also be an axially continuous bearing block if further components, such as a drive unit, are to be arranged on the winding shaft on the side of the bearing block facing away from the door curtain.
  • a bearing block holder is pre-assembled on a head plate of a door frame of a roller door.
  • This bearing block holder corresponds to the bearing block holder described above, which means that it has, among other things, an inclined sliding section and an end stop. If two bearing blocks according to the invention were or are being pre-assembled on the winding shaft in the first method step, a bearing block holder is pre-assembled on each of the two gate frames in the second method step.
  • the bearing block pre-assembled on the winding shaft is then placed on the pre-assembled bearing block holder. If corresponding components are provided on both axial sides of a gate curtain or on both gate frames, both bearing blocks are placed on the respective assigned bearing block receptacles. In a final process step, the bearing block slides down the sliding section of the bearing block holder based on gravity until it reaches the end stop and assumes the end position defined by it. Once this step is completed, the winding shaft is also placed exactly in its working position.
  • the gravity-based placement of the bearing block in the final position is supported manually and/or mechanically. This makes it possible to compensate for inaccuracies when placing the bearing block on the bearing block holder with manageable effort.
  • an exact positioning of the bearing block in the bearing block holder can be achieved by manually and/or mechanically influencing the gravity-based sliding.
  • the bearing block is fixed in this after it has reached its end position predetermined by the end stop of the bearing block receptacle.
  • Various types of detachable and non-detachable connecting means are conceivable for this. It has proven to be particularly expedient to fasten the bearing block to the bearing block receptacle using at least one screw, preferably two screws. Such a fixation supports the absorption of the inertial forces that occur during operation of the roller shutter and thus prevents the bearing block from slipping or jumping out of the bearing block holder.
  • the method described above significantly shortens the time required to install a winding shaft of a vertically opening roller shutter. At the same time, the number of manual work steps that often have to be carried out at great heights is reduced, which significantly reduces the risk of accidents when installing the winding shaft.
  • Fig. 1 shows a device known from the prior art for installing a winding shaft 12 of a vertically opening roller shutter 10.
  • the roller shutter 10 comprises a winding shaft 12, which is shown in the illustration Fig. 1 a gate curtain is wound up.
  • a bearing block 14 is arranged on the winding shaft 12 and serves to support the winding shaft 12 and to absorb the forces acting on the winding shaft 12.
  • the bearing block 14 is fixed in the axial direction on a gate frame 18, which in the context of the present application includes both a vertical guide and a head plate.
  • the gate frame 18 is equipped with elongated holes for this purpose, which enable precise placement of the bearing block 14 and thus the winding shaft 12.
  • the bearing block 14 is designed to be axially continuous, since a drive motor 24 including necessary additional components such as controls and gears is arranged on the side of the bearing block 14 facing away from the door curtain.
  • FIG Fig. 2 A method for installing a winding shaft 12 using the device described above is shown in FIG Fig. 2 schematically illustrated.
  • a bearing block 14 was pre-assembled on the winding shaft 12.
  • the winding shaft 12 with the bearing block 14 arranged on it and the already wound door curtain is now roughly placed at the later installation location. Due to the heavy weight and often great height at which the installation takes place, this step is usually carried out with a forklift or other more or less suitable aid.
  • the fine adjustment and fixation of the bearing block 14 on the gate frame 18 is then carried out manually, with this step posing a significant risk of accidents due to the height and weight of the winding shaft 12. This means that the possibility of exact placement of the winding shaft 12, which is provided by the elongated holes provided in the gate frame 18, is often not perceived or cannot be perceived.
  • the device according to the invention dispenses with such a possibility of fine adjustment and instead enables a method that allows faster installation with a reduced risk of accidents for the installation personnel.
  • Fig. 3 shows a roller shutter 10 according to the invention with such a device.
  • an axially continuous bearing block 14 is arranged on a winding shaft 12.
  • the device according to the invention now comprises a bearing block receptacle 16. This consists of a fastening section via which the bearing block receptacle 16 is fixed on the gate frame 18.
  • the bearing block holder 16 includes a sliding portion 20 which is inclined and an end stop 22 which extends from the lower end of the sliding portion 20 at an acute angle in a substantially upward pointing direction.
  • a method according to the invention for installing a winding shaft 12 of a vertically opening roller shutter 10 is based on the schematic illustration in Fig. 4 to be introduced.
  • the rough placement of the winding shaft 12 is again carried out using a forklift or other suitable lifting device.
  • the bearing block 14 slides down the sliding section 20 to the end stop 22.
  • the high weight of the winding shaft 12, which is transferred to the bearing block receptacle 16 via the bearing block 14, causes the originally acute angle between the sliding section 20 and the end stop 22 to be deformed into a right angle. This gives the bearing block 14 a flat contact with both the sliding section 20 and the end stop 22, which defines the end position of the bearing block 14.
