Description

The invention relates to a protective door according to the preamble of claim 1

Protective doors or security doors of the aforementioned Art are well known and, for example, in each Office building in use, so it so far no special requires written proof. These safety doors so they do not block the way unnecessarily, as a rule kept open by means of so-called locking devices. The protective door consists of a door leaf, which in case of fire on the one hand a smoky conclusion between the two of creates escape route areas to be separated and that itself has a certain fire resistance to the two Rescue route areas in case of fire, at least for a certain Time (for example 30, 60 or 90 minutes) safely from to separate each other. For example, according to the standard T30 RS (see also DIN 4102 and DIN 18 095) are such Provide protective doors in an escape route every 30 m. by virtue of the vertically extending, at corresponding wall or Blockzarken attached swivel axes of the door leaves is the Rescue route in the area of the protective doors disadvantageously restricted, which, for example, in hospitals moving Beds in the corridors (escape routes) difficult or hindered. Furthermore, if no locking device is provided, darken these self-closing trained doors beyond the rescue route, which according to the currently known state of the Technology only by using very cost-intensive, glazed Protective doors can be changed.

As these safety doors are installed regularly only for reasons of safety be (have) and only very rarely the need exists As a rule, these doors are actually subdivided the trained as a conventional way as a connecting passage To use escape route, is the desire that one as little as possible of these safety doors sees or that this the use of serving as an escape route a little as possible hinder.

The invention is therefore based on the object, a protective door of the type mentioned in the simplest possible way to continue to form that this regular use the escape route as little as possible, in Fire but ensures a safe fire.

This task is with a protective door of the aforementioned Type by the listed in the characterizing part of claim 1 Characteristics solved.

According to the invention, it is thus provided that the pivot axis horizontally arranged near the ceiling and the door leaf as a rule (ie if there is no fire) by the locking device is positioned plane-parallel to the ceiling is. In principle, the protective door is like one on the ceiling fastened flap formed in the event of fire swivels and divides the escape route into two rooms. The In addition, the statement "near the ceiling" expresses that the pivot axis, for example, in a suspended Ceiling at least closer to the ceiling than the ground is assigned, preferably of course in this case in the plane of the suspended Blanket. Furthermore, the proviso "plane-parallel to Ceiling "express that the door leaf, at least substantially parallel to the ceiling, so in this way, as a rule at the same time as an inconspicuous false ceiling to serve. On a preferred construction will be below discussed in more detail.

For the sake of completeness, reference is made here to DE 28 25 865 Al referenced from the indeed known a flap for animals is, but this has no fire protection function and is in addition, even regularly only as part of the door leaf a larger door for people trained.

Other advantageous developments emerge from the dependent Claims.

The protective door according to the invention including its advantageous Further developments according to the dependent claims below with reference to the drawing of an embodiment explained in more detail.

It shows

FIG. 1
in section from the side of an escape route (escape direction F) with the protective door according to the invention in the closed state (fire);
FIG. 2
in section the escape route according to Figure 1 with the protective door according to the invention in the open state (standard case);
FIG. 3
in section from the front the curse path according to Figures 1 and 2 with the protective door according to the invention in the closed state (fire);
FIG. 4
in section the transition region between wall and protective doors according to section BB in Figure 3.

In the figures 1 to 4, a preferred embodiment of Protective door according to the invention for a rescue route 1 from different View positions shown. This includes a pivotally mounted door leaf 2 with one at the one Side edge 3 provided pivot axis 4. Here is the door leaf 2 operatively connected to a locking device 5, the this usually holds in open position or in case of fire puts in closed position while the one floor 33, Walls 9 and a ceiling 6 having rescue route 1 in two Rooms 7, 8 divides. The rescue route 1 has, for example the cross-sectional dimensions 2.5 m (width) x 3 m (height).

Essential for the protective door is now (and this applies to all possible embodiments) that the pivot axis 4 horizontally running arranged near the ceiling 6 and the door leaf 2 as a rule by means of the locking device 5 plane-parallel is positioned to the ceiling 6.

As already mentioned, the protective door functions to a certain extent like a flap, which as a rule (Figure 2) the rescue route completely free and in case of fire (Figure 1 and 3) for a smoke-tight finish between the by the Folding down the door panel 2 resulting rooms 7 and 8 provides.

To ensure that escaping persons in case of fire even with the protective door already folded down, still light can save, it is provided that the door leaf 2 in the direction of escape F is formed aufschwenkbar. One of room 7 The coming person can therefore, as will be discussed in more detail, the door leaf 2 burst open in the direction and in this way get into room 8. For this purpose, as shown in FIGS. 1 and 3, advantageously provided that on the door panel 2 preferably an actuating element 10 on both sides (eg a door handle) is arranged for manual operation of the protective door. This Actuator 10 is operatively connected to a locking mechanism 12 (shown schematically in FIG. 3), which in turn is arranged on the walls 9 of the escape route 1 Closure elements 22 can be brought into engagement (see in particular FIG. 4). These closure elements 22 For example, they are attached to the wall 9 before plastering Molded strips that after plastering (the plaster is represented by those marked with small triangles Layer) form the wall surface in a planar manner. According to Figure 2 may remain only the edges of the Strip and the recess for the locking bolt of the locking mechanism 12 visible. Alternatively, of course, come also strips (eg L-shaped strips), which protrude slightly from the wall (for example, when attached after plastering) and in this way also as a stop for the door leaf 2 and as compensation for uneven walls serve.

To ensure that in case of fire no smoke from one Room 7, 8 can overflow to the other, is at the side edges the door leaf 2 in case of fire intumescent intumescent material 23, preferably expandable graphite, arranged. About that In addition, as shown in Figure 4, preferably on the Side edges of the door leaf 2 elastic sealing lips 24 are arranged.

To users of the aisle (escape route) before folding down warning the guard is beneficial in Rescue Route 1 Optionally, an optical and / or acoustic signal generator 11 (eg warning lamp, siren) arranged, which (which is not extra is shown) electronically with the locking device. 5 is interconnected.

Another essential aspect of the invention Protective door is that the door leaf 2 a the escape route 1 about corresponding width and height (remaining joints deducted), d. H. in contrast to the previously known protective doors with vertical pivot axes is the new Protective door (apart from those exemplified above, at the walls 9 fixed strips) practically frameless.

With regard to the already generally mentioned locking device 5 is advantageously provided, this particular for the Fire a locking mechanism 12 and in particular as a rule, means for keeping open 13 of the door leaf. 2 includes. The latter preferably consist of at least one a cable 14 having cable 15, the one from the ceiling 6 arranged cable lift mechanism 16 is formed is, wherein the Seilaufzugsmechanismusabgewande end of the rope 14 is connected to the door leaf 2. The cable lift mechanism 16 preferably comprises at least one (shown are two) spring-driven Seilaufwickelrolle 17th

Furthermore, it is advantageously provided that the means for keeping open 13 of the door leaf 2 comprise an electromagnet 18, which is arranged on the ceiling 6 and usually with a provided on the door leaf 2, magnetically active counter element 19 is contact-connected. As a rule, the door leaf is so (in addition to the force of the cable lift mechanism) much like at a conventional locking system by electromagnetic force held in open position.

For automatic actuation of the locking device 5 in Fire (ie to fold down the door panel 2) are the Means for keeping open 13 of the door panel 2 preferably electronically connected with a smoke detector 20. This smoke detector 20 can, for example, as shown in Figures 1 and 2, be arranged on a false ceiling.

To the protective door according to the invention particularly easy on site to be able to mount, is advantageously provided that the Swivel axis 4 of the door leaf 2 on a positioned on the ceiling 6 Receiving box 21 is arranged. In the recording box 21 are preferably the means 13 for holding open the door leaf 2 arranged. This embodiment is beyond also because of particular importance, because in escape routes there is almost always a false ceiling to accommodate installations, like pipes and lines, visually and also fire protection technology to be disconnected from the rescue route. These are preferably both the receiving box 21 and the false ceiling fire resistant formed (eg with a fire resistance F30, F60 or F90). The receiving box 21 can thus, as in the Figures shown, positioned at the level of the false ceiling become; the folded-up door leaf 2 then forms the optical Graduation. The decor in this case are any Given design options.

Another advantageous developments with regard to the assembly the protective door according to the invention consists in (see 3), that the door leaf 2 at least from a support frame 25, which is preferably assembled from so-called C-profiles is, and optionally one or more arranged thereon Plate elements 26 is formed. Regarding the plate elements 26 is also advantageously provided that these are formed from calcium sulfate, calcium silicate or vermiculite and optionally via a tongue and groove system 27 or in several, mutually offset layers are interconnected.

To the safety gate, which is yes due to the requirements regarding Fire resistance and smoke protection is relatively heavy, It is advantageous to be able to move easily (to open and to swing) provided that on the door panel 2 at least one (shown two) vertically extending guide rail 28 are arranged is, with one end 29 of a guide rod 30 slidably stored in the guide rail 28, the other end 31 of the guide rod 30 is rotatably hinged to the ceiling 6 and the Seilaufzugsmechanismusabgewande end of the cable 14 at the guide rail side end 29 of the guide rod 30 is attached is. Kinematically this results in a during the pivoting movement changing point of attack of the rope 14 on the door leaf 2. This in turn means that the to be applied for pivoting force changes, namely in the Way that the auxiliary power of the cable lift mechanism 16 at closed position is relatively small, but with increasing Opening angle becomes larger. This can be (as Ensure that the opening of the Protective door (if the locking mechanism 12 is not closed is) only a maximum force of 100 N required is.

Furthermore, it is advantageously provided that for unambiguous determination the protective door in closed position in the area of Swivel axis 4 an acting on the door leaf 2 auxiliary pressure spring 32 (here leaf spring) is arranged.

Finally, it is advantageous to reduce the pivoting range provided that the door leaf 2 at least two parts trained, with a preferably about half the door height arranged, horizontally extending hinge the two so resulting parts together. At this Embodiment is moreover an appropriate one if necessary Locking mechanism provided to the two parts to connect with each other in case of fire to a stiff door leaf.
