Definitions

  • a security door of the construction described at the beginning is known from the German utility model 75 25 876 become.
  • the gas-tight door described here has a locking mechanism on each side of the door leaf for opening and closing the latter has an actuator.
  • the hollow seal is on one of those Actuator switchable pressure device connected, with a closing or an opening the position of the actuating element an associated printing device in a flowable medium in the hollow seal under pressure setting first position is switchable. Hence hangs the filling of the hollow seal ultimately from the position of the actuating element belonging to the closing mechanism from.
  • the well-known hollow seal also serves at most, a gas-tight seal between Manufacture door leaf and door frame.
  • Security doors and especially sterile doors are used generally to delimit safety and sterile areas.
  • This can be, for example pathogen-free areas (e.g. SPF animal husbandry, cell and tissue cultures) with the exclusion of ubiguinary germs using positive room pressures as well act like infectious areas (viruses, bacteria, Fungi, yeasts, spores, etc.) to prevent Environmental contamination using negative Room presses.
  • pathogen-free areas e.g. SPF animal husbandry, cell and tissue cultures
  • infectious areas viruses, bacteria, Fungi, yeasts, spores, etc.
  • bio and genetic engineering security areas as well as from physical and chemical security areas typical applications for a security or sterile door.
  • bio and genetic engineering Security areas is required to exclude to reach ubiquitous germs. The demarcation of wants physical security areas, for example environmental contamination from radionuclide areas Prevent air transfer and nuclide carryover.
  • the circulating Door frame a lintel element, door reveal elements and has a door sill element.
  • the door frame is with connected to the assigned room wall, which is is preferably a lightweight wall, because at Sterile areas often have metal walls in sandwich construction be used.
  • Security doors are in different designs known.
  • One embodiment is particularly practical known, in which the door leaf in his Door leaf edge, facing the frame, a circumferential, the Has a sealing hollow profile belonging to the sealing system, which is connected to the door leaf.
  • the Hollow gasket is not a hose gasket, though a hose seal means a seal, which have a round or rectangular tube cross-section has that is inflatable.
  • Sealing hollow profile is a longitudinal one, in cross section M-shaped indentation provided, which is located under the influence of the pressure medium causing the seal as it were protruding and into an assigned depression borders as well as inversely with pressure relief moved back.
  • the invention is based on the technical problem such a security door, especially a sterile door, to create, in which both the seal and the pressure relief and associated opening of the Door leaf, can be done in very short periods of time and which is independent of mechanical devices Locking enabled.
  • the invention proposes to achieve this object a generic security door, in particular Sterile door for access to security rooms and Sterile rooms opening, before that Compressed air source, the compressed air line system and the Compressed air inflow cross section of the hose seals so are set up that the sealing force in addition closed door leaf against the door frame via friction locking locked quickly and securely, and that that Pressure relief system and the compressed air discharge cross section the hose seal are set up so that the door leaf locked via friction locking in one Relief period from 1 to 6 seconds, preferably from 1 to 3 seconds.
  • the invention is based on the knowledge that at Use one for appropriate pressures of the pressure medium installed hose seal on a positive Locking between door leaf and door frame can be dispensed with using the sealing profile, if the sealing force is chosen and set up so large will be that the locking is done by friction can. This avoids and from fitting problems resulting disadvantages. From the fact that very high Pressures of the pressure medium and therefore very high sealing forces are used, it also follows that the Sealing and associated locking in extremely short period of time and that because of the high restoring forces even in extreme the pressure relief of the hose seal and thus the opening of the door leaf can be achieved.
  • the extremely quick locking and opening of the door leaf is optimized in that a sufficiently large compressed air inflow cross section and compressed air discharge cross section for the hose seal is realized.
  • High pressures of the Pressure medium which is not just compressed air, but can also be a different gas, says Pressures in the order of, for example, 3 and more bar.
  • an electrical proximity switch e.g. Reed contact is checked.
  • a manual valve can be used in the pressure relief system installed for emergency release in case of danger be, for example, next to the door frame the wall and with which the door leaf is independent opened by the electronically controlled sealing system can be.
  • the door leaf and the surrounding one Door frame preferably matched rounded Corners in order to ensure a flawless even in the corner areas Sealing between the sealing counter surface and the To reach the hose seal.
  • Rounding the frame corners can be done using appropriate fillers the door frame only for walls with a lightweight construction only the invention sees a minimal wall support before that the door frame has high strength and inherent rigidity and consequently as self-supporting Door frame is formed.
  • the Hose sealing facing sealing surface preferably designed as a smooth surface so far To facilitate disinfection measures. For this reason is also on a fold in the door frame and the door leaf waived. Because bacteria to be killed are in tight Hardest to hit niches.
  • the gap between that Door leaf and the door frame is so wide that sufficient access to the hose seal for the disinfectant.
  • the door leaf is standing within the scope of the invention essentially symmetrical Frame profile, so that the disinfectant effect on both Sides is equivalent.
  • the invention further provides that the door leaf is designed as a double-leaf door leaf is and that the door leaf and possibly the door frame soundproof and possibly heat-insulated with insulation material are. This becomes a requirement in the animal sector to suppress extraneous noise. The sound insulation is clear about the values of comparable doors out.
  • the door leaf is a smooth wall Door leaf with just one handle, e.g. Shock or pull handle, and optionally a door window.
  • the hose seal consists preferably of permanently elastic material and is therefore characterized by a long service life.
  • the Compressed air inflow cross section and the compressed air outflow cross section are identical. A sufficiently large cross-section for a quick inflow of compressed air in the train the seal and a quick discharge of the compressed air can be reached in the course of opening the door leaf implement, for example, an elongated hole cross section.
  • the compressed air inflow cross section and Compressed air discharge cross section of 2 or more compressed air channels are formed in the door leaf, via hose plug-in couplings are connected to the hose seal and are connected to the compressed air line system.
  • the hose plug-in couplings ensure an in manufacturing technology particularly simple embodiment.
  • the hose seal arranged in a circumferential groove of the door leaf, in such a way that they come on in a depressurized state the upper edge of the groove closes as well as in the inflated State protrudes beyond the top edge of the groove.
  • the hose seal can have a circular cross section.
  • the double-shell Training the door leaf brings the further Advantage that foaming can be carried out.
  • This also applies to the door frame, so that the invention Security door also soundproof at the same time and can be carried out with thermal insulation.
  • the security door 1 shown in Fig. 1 is for a enabling access to a safety or sterile room Room opening determined. If you take the other figures added, you can see that the security door is a door frame 2 and has a single-leaf door leaf 3, which with With the help of door hinges 4 is connected to the door frame 2. For the rest is a sealing system that can be switched on and off 5 provided with pressure medium actuation, to which a plurality of components and assemblies belonging below are explained.
  • the door leaf 3 carries in its door leaf edge, the frame facing a circumferential hose seal 6, the Sealing system 5 heard. You can see the circumferential Hose seal 6 in FIGS. 3 and 4 and in sections 5 and 6.
  • the sealing system 5 is predetermined Inflatable sealing force against an autogenous restoring force. 6 shows the inflated state. Autogenous restoring force means that the restoring force due to the elastic deformation of the hose seal 6 developed when inflated.
  • the facing the door leaf 3 Frame surface is as flat, and in working condition practically non-deformable sealing counter surface 7 is formed. For this purpose, reference is also made to FIG. 6. Practically non-deformable means that a positive connection between the inflated hose seal and the Counter sealing surface does not enter.
  • Fig. 1 takes one that the sealing system 5 a pressure medium source 9, preferably a compressed air source or another gas source, a compressed air line system 10 with control valves 11 and a pressure relief system 12 with a control system. With these components is when turned on Sealing system 5, the hose seal 6 inflatable. at turned off sealing system 5 is the hose seal 6 inflatable, under the influence of the already explained restoring forces.
  • the pressure medium source 9 and the pressure medium line system 10 are set up so that the sealing force against the closed door leaf 3 Door frame 2 securely locked using a friction lock.
  • the Pressure relief system 12 is set up so that it Door leaf 3 locked in a frictional engagement Relief period of just a few seconds unlocked.
  • the restoring force of the hose seal 6 is corresponding dimensioned.
  • the invention is the hose seal 6 in a circumferential groove 13 of the door leaf 3 inserted, and in such a way that they are in the pressure-relieved state at the top edge the groove 13 closes, as shown in FIG. 5 in particular and 6.
  • the interpretation is like this hit that in the inflated state the hose seal 6 protrudes over the upper edge of the groove 13.
  • the hose seal 6 has in the embodiment in the pressure-relieved Condition an essentially rectangular tube profile.
  • the compressed air line system 10 connecting components 14, which has a door hinge 4 and a hinge 15 inserted into the door leaf 3 are and connected to the hose seal 6 there become.
  • the door leaf 3 is a double-shell in the embodiment Door leaf 3, it is for the purpose of sound and Thermal insulation as well as frame 2 are foamed.
  • the door leaf 3 and the surrounding door frame 2 face each other coordinated rounded corners.
  • the door leaf 3 is as a smooth-walled door leaf with only one handle 16 and a door window 17.
  • the compressed air inflow cross section and the compressed air outflow cross section of the Hose seal 6 are of two compressed air channels 18 in the Door leaf 3 formed by hose plug-in couplings the hose seal 6 are connected and with the Compressed air line system 10 are connected.
