DE4118633A1 - Fast action, fire station door - Google Patents

Abstract

The fast-action door, such as multi-leaf type for a fire station etc. is rapidly opened by a power accumulator, without the need for mains electricity. It has one or more telescopic tube assemblies, whose sections are thrust one inside the other in opposition to a compression, coil spring. The door leaves can be arranged to run up against a shock damper in the opening direction.

Description

The invention relates to the rapid opening of multi-leaf, especially four-wing, fire department high-speed doors. These wings are - using the example of a four-wing gate - Articulated with each other about approximately vertical axes connected or in the approximately vertical side areas of the Frames articulated, otherwise they run towards the middle of the closing gate opening towards the gate wing in the loading rich of their front edges in ceiling rails. These gates must also be used without an intact energy supply casting supply systems, e.g. B. the electrical supply network, work and must therefore be equipped with energy stores.

Gas springs could be used as energy storage devices to open the gate quickly. However, gas springs have insofar as two disadvantages in that it concerns itself on the one hand Lich not set their working pressure and at others with regard to the force or Work characteristics are temperature dependent.

The invention has for its object a quick run gate of the type in question with regard to the opening Force adjustable and thus with regard to the opening area to make speed selectable in such a way that a temperature dependency at least largely avoided is.  

The object is achieved in that a Lift mechanism in the form of a telescopic tube device is provided against the force of a - in particular received in it - compression spring can be pushed into one another is. In a preferred embodiment there is also a Shock absorber provided against which the gate wing or the entire moving door leaf directly or indirectly at transition runs into its open position. It should be noted that the fire brigade gates dealt with here in case of doubt very much must be opened quickly, so that considerable kineti energies are released when reaching the opening position of the door leaf must be intercepted in a shock-absorbing manner.

Basically, two preferred solutions have to be specified, namely:

• 1. The spring telescopic tube is at one end on the inside side of a frame-side gate wing connected, wuh rend the other end of this telescopic tube on an Ausle ger is rotatably held by the running rail or Frame protrudes from inside the equipment hall. To this In this way you get a lever arm that is on the frame side steered gate wing pushes outwards when this is released accordingly. Hangs on this gate wing then, if necessary, the further gate located towards the center of the gate wing, which is guided in a ceiling-side track is. The shock absorption takes place in such a way that on the outside Shock absorber is provided with one on the outer Gate wing or the one facing the center of the gate finally takes effect, attacks. This boom can thereby as an extension or in the area of the roller be arranged, which engages in the running rail. Because of the arrangement of this stop is its way in the direction the track predetermined, so that the shock absorber on this direction of movement can be precisely aligned can, by also fixing it to the frame and arranges its working stroke in the direction of roller displacement.  
• 2. Another solution to the problem is one End of the spring telescopic tube on the running rail or frame lay down while the other end on one inside is directed towards the outrigger of the door leaf, in particular arranged such that the boom around the Frame-side hinge axis of the frame-side gate wing can pivot. Here you could also use the shock absorber Select the arrangement as described for the above solution is provided, but you also have the here Possibility of the shock absorber on the inner tube of the telescope fix the tube and the outer tube with a slot to be provided so that it is opposite the bracket of the The shock absorber can move like this Drawing shows. Then it becomes a driver arranged on the outer telescopic tube, which with a flexible stop of the shock absorber works together. On this way the shock absorber is always applied provided in its precise working direction. Furthermore you can also use this solution in connection with the previous one based arrangement of the spring telescopic tube ver turn.

In general, the following should be noted to solve the problem ten: The characteristic curve of a gas spring is not linear, and in such a way that what to store the force ge in the course of the closing process of the door leaf shoots, relatively high pressures or forces at over lead to the final open position must be spent. The opposite is the characteristic of a normal compression spring approximately linear, which is why the storage of the force in a such spring is easier to do with Consequence that the door leaf is easier in the lock lung can be transferred. If you want the power at a gasfe the influence, so you have to be relatively expensive ger and complicated design variable lever arms provide. In a telescopic tube spring according to the invention on the other hand, the spring tension can be adjusted by itself  appropriate adjustment - for example by means of a counter mother setting - adjust so that

• a) the spring is individually adjustable and
• b) the telescopic tubular spring element for different gates can be used. It should be noted that the Gate widths, for example, between 95 cm and 125 cm vary. The actuation of such different widths Gate leaf elements are not with one and the same gas spring manageable. The adjustability of the telescopic tube spring allows the use of the same el mentes for these different gate wing dimensions.

Another advantage is that such a telephoto Scope tube spring element even with gates already installed can be used later, precisely because the one adjustability of the spring force is given.

Because fire station doors of the type in question here otherwise due to failure, for example network-dependent, ge fed drives must be operable by hand provide manual or rope-operated traps that counter withstand the spring pressure of the lift mechanism. Different pressed, these gates reach their closed position under Be insert a snapper lock, the Rie such a snapper closure by hand using a rope can be actuated. These requirements enable the An organization of the entire gate operating device in the area the upper roller track, so that it from passing vehicles is not reached.

The two drawing figures show the structure of an er power storage according to the invention, together with shock absorber fer in an integrated design.
