Definitions

  • the invention relates to a lamella for an industrial door according to the preamble of claim 1, an industrial door according to claim 8 and a method for producing such a lamella according to claim 11.
  • roller doors are known in practice, which are designed according to the shutter principle with a door leaf of fins and an upper winding shaft. These roller doors are suitable as exterior finish for buildings z. B. during business interruptions, but are normally held in the open position during operation, since opening and closing movements require a lot of time due to the very slow running.
  • the lamellae of these high-speed industrial doors are usually made of aluminum. In practice, however, it is often desired that the area behind a closed gate is visible, so that, for example, not from both sides forklift want to pass through the first opening gate.
  • a transparency of the door leaf is desired, as it is known for example from so-called soft PVC roller doors.
  • These can also be designed as high-speed roll-up doors, wherein the door leaf is designed as a curtain, which is wound up when opening the door above the door opening.
  • This curtain made of soft PVC or the like can be formed substantially over the entire surface, ie transparent over the entire door height away.
  • the windings of the door curtain are here as in conventional roller doors in the winding directly on each other so that they scratch and pollute accordingly, which reduces the transparency of the blind over time.
  • Another disadvantage of these roller doors is that this curtain, although usually held at the side edges in vertical guides, tends to buckle in the central area at higher wind forces due to stretching of the material.
  • this frame-like lamella consists of an upper and lower profile strip, which are rigidly connected to each other at their respective end regions and larger door widths in the central region of the door leaf via a vertical web. The vertical webs are bolted to the moldings.
  • Another disadvantage of this design is the significantly higher assembly costs in the provision of such a transparent blade against a lamella produced as a one-piece profile.
  • the cost of such a transparent lamellae are therefore several times the price of conventional lamellas. They are therefore used, if at all, only as viewing slits in a small portion of the door leaf.
  • the US 4,569,383 describes the example of a sectional door a construction in which panels such as glass, etc. are held in the individual sections.
  • a respective frame is provided, wherein the frame elements surround the associated panel on all sides and record this form-fitting manner in grooves, in which the edges of the panel are inserted.
  • a filler material such as a putty is provided.
  • an industrial door is also known in which slats made of extruded plastic are used. These can be designed to be transparent completely or even only in a partial area. Since the lamellae are made of, for example, GFRP or PMMA, they have a very low weight in comparison to lamellae made of aluminum. The use of this plastic slats of a flexible material is thereby possible according to this known industrial door in that the spiral portion of the side guide has a steadily curved spiral shape, so that the dynamic loads of the door leaf can be kept within limits. This industrial door has proven to be very advantageous in practice for many applications. Thus, very high speeds of up to 3 m / s can be reliably achieved here. At the same time it is also possible to form the door leaf substantially continuously transparent.
  • JP-A-08240084 a blade with the features of the preamble of claim 1 has become known.
  • the invention is based on the object, a generic blade in such a way that a reliable connection between the individual parts of the lamella is achieved that the door leaf of an industrial door while maintaining the well-known, for example, from the high-speed spiral door suitability for an outdoor - variable designable and especially is transparently aussentbar. Furthermore, the invention is intended to provide a corresponding industrial door and a method for producing such a lamella.
  • a blade having the features of claim 1.
  • This has two extending over the length of the lamella profile elements and arranged between them, optionally transparent plug-in plate, wherein the profile elements each have a substantially U-shaped profile groove for receiving the longitudinal edges of Have insertion plate, and wherein between the longitudinal edges of the insert and the inner surface of the profile groove in each case an elastomeric plastic part in the press fit, that is under deformation of the plastic part relative to the unloaded state, is arranged.
  • the press fit of the plastic part between the edges of the insert and the inner surface of the profile groove is such that it produces holding forces against withdrawal of the insert from the profile, wherein it has a relative movement of the insert relative to the profile elements in the longitudinal direction of the lamella allows.
  • this blade is even better for an industrial door, which serves as an outer closure and thus is exposed to thermal effects such as direct sunlight.
  • the different coefficients of linear expansion of the materials therefore do not lead to any tension in the profile elements or on the plug-in plate.
  • the elastomeric plastic part absorbs these expansion forces and, due to its elasticity, permits a relative movement in the longitudinal direction of the lamella.
  • the industrial door according to the invention can then be used reliably even for very large door widths of six meters and more.
  • Another advantage of the slats according to the invention lies in the fact that this mechanism of action is independent of the material of the insert comes into play.
  • the design freedom in the manufacture of the lamellae expands example, all or even some of the slats of an industrial door with transparent plug-in, or perforated insert plates made of metal, as well as color-designed plug-in plates, etc. are provided. This allows orders to be made according to customer requirements.
  • Another essential advantage of the invention is that for the first time even without much effort, a variation of the slat width, i. the division of the door leaf, can be performed.
  • a variation of the slat width i. the division of the door leaf.
  • only the width of the plug-in plate corresponding to the desired pitch of the door leaf to choose, while such a variation, for example, in the extruded plastic slats only by providing a new, costly extrusion tool is possible.
  • an industrial door equipped with the lamellae according to the invention continues to provide a reliable outer seal and can be operated without problems at high speeds of, for example, 3 m / s.
  • it is also suitable for large gate widths.
  • the plastic part may be made of EPDM, i. an ethylene-propylene rubber.
  • EPDM i. an ethylene-propylene rubber.
  • This material has been found in experiments to be particularly suitable for the purpose of the invention.
  • this material has a good resistance to weathering and ozone and is reliably applicable at very different operating temperatures.
  • the mechanical properties of this plastic are particularly well suited to produce the inventive purpose of a reliable and stable coupling of the insert with the profile elements.
  • Another advantage is when the plastic part is prefabricated as a U-profile. This ensures that the plastic part reliably comes to rest at the desired location and does not slip during the production of the interference fit. This simplifies the production of the lamellae according to the invention and increases the reliability of the industrial door.
  • the legs of the U-shaped plastic part may have at their free ends a clear width from each other, whose dimension is less than the thickness of Plug-in plate is. This ensures that the plastic part is even more stable on the plug. The elastomeric plastic part can thereby perform its function even more reliable.
  • the plastic part can be even more accurately applied to the edge of the insert.
  • the recesses make sure that the plug-in plate can be inserted to the crosspiece of the plastic part, wherein the edges engage in the recesses on the longitudinal edges of the insert. As a result, undefined states in this area can be better avoided.
  • the elastomeric plastic part can be inserted in a simpler way and more accurately in the profile.
  • this inlet slope controls the stretching of the elastomeric plastic part during the Eindrückvorgangs so that this step can be carried out with greater process reliability.
  • an industrial door is provided with the features of claim 8.
  • a method of manufacturing a sipe comprising the steps of: positioning opposing longitudinal edges of a male plate with respect to a respective U-shaped profile groove on two profile elements extending over the length of the sipe, arranging an elastomeric plastic part respectively between the longitudinal edges of the insert plate and the U-shaped profile groove, and merging the insert plate and the profile elements, wherein the elastomeric plastic part is pressed in between and deforms.
  • This method is characterized by the fact that with high process reliability and relatively little design effort a blade with the desired properties can be reliably produced.
  • process problems such as in the initially discussed bonding of the plate can be avoided in the profile elements, since according to the invention can be dispensed with a bond entirely.
  • the plastic part may in this case be designed as a U-profile and be attached to the respective longitudinal edge of the plug-in.
  • an industrial door 1 has a door leaf 2 which has a plurality of laths 21 connected to each other in an angled manner as well as a closing profile 22 for the bottom-side closure.
  • the industrial door 1 is shown in the open state, in which the door leaf 2 is wound in the region of the gate lintel, not shown to form a spiral.
  • the lamellae 21 are connected to each other via not shown Schamier pleaseden, said hinge means can be individual hinges between the slats or a continuous over the Torblatt basically hinge each in the region of each side edge of the door leaf 2.
  • a plurality of rollers 23 are arranged on the side edges of the door leaf 2 in a known manner, which engage in the guide rails 3 and serve for the lateral guidance of the door leaf 2.
  • a blade 21 is shown in section.
  • the lamella 21 has two mutually mirror-image formed profile elements 211 and 212, which are present in the installed state respectively adjacent to the adjacent lamella.
  • a plug-in plate 213 is arranged, which is indirectly connected via a respective elastomeric plastic part 214 and 215 with the profile elements 211 and 212.
  • the profile element 212 is shown in more detail. It has a profile groove 2121, the inner surface of which contains a toothing 2122.
  • the toothing 2122 is designed such that the teeth extend parallel to the bottom of the profile 2121.
  • an inlet bevel 2123 is formed at the open end of the profile 2121 on both sides.
  • the further geometry of the profile element 212 is determined in a known manner from the structure of the door leaf 2, so that can be dispensed with a detailed explanation for this purpose.
  • the elastomeric plastic part 215 is shown in cross section. This is made as a molded part made of EPDM and has two legs 2151 and 2152, which are interconnected via a transverse web 2153. On the inside of the thus U-shaped plastic part 215 recesses 2154 and 2155 are further formed, which are present at the transition between the legs 2151 and 2152 and the transverse web 2153.
  • FIG. 4 The drawn in Fig. 4 with a solid line shape of the plastic part 215 corresponds to the built-in, ie the plugged onto the plug 213 position.
  • the delivery state of the plastic part 215 is also indicated by dashed lines. It can be seen that the legs 2151 and 2152 of the plastic part 215 have at their free ends a clear width from each other, the dimension of which is less than the thickness of the plug 213.
  • the profile element 211 which is not described here in detail here, is analogous, ie. mirror image formed to the profile element 212, as shown in FIG. 2 can be seen.
  • the plastic part 214 which is likewise not described in detail, corresponds in its shape to the plastic part 215, wherein it is merely attached in opposite orientation to the other longitudinal edge of the plug-in plate 213.
  • Fig. 5 is shown in more detail and in a schematic representation of how the individual elements of a blade 21 are connected together.
  • the plastic part 215 is first attached to a longitudinal edge of the insertion plate 213 only partially shown here. Subsequently, these preassembled elements are inserted into the profile groove 2121 of the profile element 212, which is only partially shown here.
  • the elastomeric plastic part 215 is elastically deformed. If necessary, it slides into the profile groove 2121 under a draft, if appropriate via the inlet bevels 2123 (see FIG. Once the inserting operation is completed, the elastomeric plastic part 215 tends to contract again and finally is stuck in the space in the interior of the profile groove 2121.
  • the plastic part 215 comes into engagement with the toothing 2122. Since the plastic part 215 at the same time comes to lie under permanent deformation in the profile 2121, the pressure is transmitted to the main surfaces on the longitudinal edge of the plug 213, so that it is held reliably , The connection in the region of the profile element 211 is produced analogously.
  • the plug-in plate 213 is fixed in this way, it continues to be elastically clamped between the profile elements 211 and 212. Therefore, on the one hand a very high holding force - a typical amount is 300 N / dm - against pulling out the plug 213 from the profile elements 211 and 212 achieved, and on the other hand is still a relative movement of the plug 213 against the profile elements 211 and 212, in particular in the longitudinal direction the lamella possible, so that tensions due to a different expansion of the materials can be avoided by thermal action.
  • the elasticity of the plastic part is overcome at some point and there is a (reversible) sliding movement at the interfaces. This sliding movement occurs where the friction is the lowest, such as between the plug-in plate or the web and the elastomeric plastic part.

  • An example would be in addition to NBR, CR, TPE and EPM also a butyl rubber or Neoprene polychloroprenes.
  • the plastic part must not be prefabricated as a U-profile, but can also be delivered as a flat web, which is positioned centrally between the profile 2121 and the edge of the plug 213 and then pressed.
  • the free ends of the legs 2151 and 2152 of the plastic part 215 have a smaller inside diameter than the plug-in plate 213 is thick.
  • according to the invention can be dispensed with a bonding at the junction plug 213 / plastic part 215 or plastic part 215 / profile 2121.
