Automatic fire protection closure for automatic closing of openings

The invention relates to an automatic fire protection closure for automatically closing openings in walls and / or ceilings of fire section separations, preferably for use in rooms connected by means of transport rails, by means of

- A complete independent structural unit, in which essentially the simultaneous application of the functional principle of a slide that can be moved parallel to the fire section separation, is provided with an inner cutout and in which a separated section of the transport rail is fastened, followed by intermediate frames ¬ named, and a door pivotable by 90 ° to 180 ° about a pivot point, hereinafter called sealing element, and by their constructively predetermined interaction the desired goal is achieved.

The building regulations of the federal states and the technical rules of the insurers require the building to be divided into fire sections. 1 Technical change and rationalization through

Automation requires a simultaneous and increasing ^¬ connection of the individual building sections ^¬ by means of transport systems. This also creates openings in the fire compartment dividers.

5 openings which are only permitted in exceptional cases and which are usually to be closed by self-closing fire-resistant closures.

To securely close _. To ensure openings in 0 fire section separations, so-called "fire protection closures" are arranged at the relevant points, which are to automatically, safely and immediately close the use-related opening in the event of a fire. Furthermore, these "fire protection closures" should at least correspond in their classification to the fire resistance duration of the wall and / or ceiling on which they are used.

0 The area of application for fire protection closures and their structural design is diverse.

One essentially divides into two main groups, which - as the definition of the term below shows - differ significantly from the technical task and therefore also in its conception.

1st group: fire protection barriers for generally 0 ^' used openings

2nd group: Automatic fire protection closures for openings in transport systems

5 The two groups differ as "Fire barriers for generally used openings" (1st group) are standardized or constructionally approved components in the form of self-closing doors and closures, such as. B. flaps, roller shutters, gates, in the known designs. They are closed and / or close automatically in the event of a fire. With a few exceptions, they are only used for wall openings that end with the lower edge on the upper edge of the floor.

10 d. H. Fire protection closure and floor together form the protective function. They cannot be used for ceiling openings.

"Automatic Feüerschutzabschlusse for" Öff- ^{■ * •} * ^• * ^{'calculations} in transport equipment "(second group) are also parts by building requiring approval Bau¬, but in the form of self-closing valves or flaps al¬ also considering ler possible interfering influences of Transport

In the event of a fire, close the opening automatically, securely and immediately. Their suitability is also checked for their interaction with transport systems; in the vast majority of cases they are completely integrated in the technical system of transport

25 system integrated and work there fully automatically in the transport rhythm.

It is therefore no longer a question of conventional "components", but of construction elements which are the same

30 times are "component" of the building and "machine part" of the transport system. Furthermore, with a few exceptions, they are used for wall openings, the lower edge of which is at a certain distance from the upper edge of the floor

35 lies. They can also be used for ceiling openings. In addition - in contrast to Group 1 - an acceptance test on the building may be necessary.

As the above comparison shows, in view of the existing building inspectorate and / or underwriting regulations and because of the different requirements for the functional technology, it is not possible for group 1 fire protection closures if there are openings to be secured in fire compartment separations through which the transport systems are led to use.

For such needs, only fire protection closures of group 2 can be used, and only if their usability has been demonstrated.

In operational practice, there are two functionally different basic types (systems) of so-called ^* "fire protection closures in the course of rail-bound conveyor systems", ie fire protection closures of group 2, namely:

System A = open as scheduled System B = closed as scheduled

A comparison of the two systems makes it clear that very different requirements are placed on the qualification of the fire protection closures and on any additional components that may be present, such as. B. devices for moving out rail pieces of the transport systems.

With system A it is only a matter of ensuring the movement processes of the fire protection closures and the additional components only a few times. Experience shows that simplified technical solutions can lead to the goal here.

With System B, things are very different. These protective seals are completely integrated in the technical system of the transport system and work there fully automatically in the transport rhythm. As a result, they perform a double function, namely:

- During normal transport operation, the fire protection closures are loaded just like any other "machine part" of the transport system because of their mechanical, electrical and functional connection. They are therefore inevitably subject to wear and tear in daily operation. From the point of view of the fire protection engineer, they are therefore used for other purposes.

- In the event of a fire, the same fire protection closings should still meet all the requirements of their fire protection task in the sense of a "component" of the building.

The contradiction contained in this double function does not do justice to the current practice of the known fire protection closures in most cases, because usually only the fire protection suitability is proven and assessed in the test certificates. The buyer and / or user of a "fire protection conclusion in the course of rail-bound conveying systems" can be confident that the fire protection protection effect specified and guaranteed in the fire protection standard will be achieved, whether the expected technical 1 However, usability in relation to the needs of the transport system is not yet certain.

5 The suitability of technical usability lie with the respective transport system, the selection criteria listed below zu¬ grunde by which today Feüerschutzabschlusse ben ne¬ the obvious fire protection ^• ^"• must be designed 0 protective effect:

- How easy is the fire protection closure? Do the fire protection closures have sufficient mechanical strength for transport, especially taking into account the circumstances that after unloading at the construction site, the fire protection closures generally have to be transported to the installation site and then to the installation position under difficult path conditions?

Can transport damage have negative effects on the later operation of the transport system? ^• (The construction structure provides information about this.

- How easy is the fire protection closure to maintain?

A fire protection closure for sealing and closing openings in walls and ceilings is known from European Patent Specification 0003614, in which a sealing element which can be displaced parallel to the separation of the fire section moves from a parking position located "next to the opening" in front of the opening in the event of a fire In addition to a whole series of considerable advantages over the state of the art, the fire protection closings have in the sense of the solution published therein. two major disadvantages. These are:

- To create the parking space next to the opening to be closed, a considerable amount of space is required, which is generally not available at the construction site or is very difficult to create.

- In order to seal in the area of the transport rails to ensure ^', they must Feüerschutzab¬ conclusion with an additional device ver¬ see, by means of which, before or v / hile the closing operation of the sealing element Bautei¬ le of the transport rails from the path of movement removed and how they z.

- 0029230 - 0033126

- 0029563 - 0034705 This state of the art, which is hereby known, does not provide a sufficient solution in the sense of the building and testing principles for standard-compliant constructions and with regard to the needs of the transport system industry which exist at the same time. This is essentially because:

- The well-known fire protection closures made of steel and sheet steel have a high mechanical strength, but due to their thermal bridges due to the design and material characteristics, the temperatures on the side facing away from the fire are too high. In addition, these constructions have the property of warping in the event of one-sided fire exposure. The passage to the fire section to be secured is opened, which means that fire and smoke can then pass through without further hindrance.

The known fire protection closures, in which the support frame and sealing element are made entirely of fire protection insulation panels and which close horizontally and vertically, have serious disadvantages owing to the physically determined property of the construction materials used in connection with the selected construction structure. Thus, the structural components made from this material do not have sufficient inherent strength, which is evident from the breakage rates during transport.

In addition, there are considerable difficulties in assembly on the construction site. For example, it is due to the unavoidable unevenness of the surface of walls and ceilings ^• permanently damage in the form of breakdown of the support frame, even if the fixing screws with great care intensified by the fact that the fitter at the construction site, and this is even due to the design, has to dismantle the fire protection closure assembled in the production for the most part in order to be able to carry out the assembly. After assembly or fastening to the fire wall, the fire protection closure is actually completed, the high error rate that is observed to be observed must be described as a serious disadvantage.

- The well-known fire protection closures, in which a sealing strip arranged at the lower or side end of the movable sealing element, also foaming, engages a 4 - 5 mm wide slot • of the component of the transport system that is passed through the fire wall opening and thus a certain seal is to be achieved, no fire tests positive could exist because this constructive training still leaves so much free passage that fire and smoke can pass through without further hindrance. This free passage essentially arises from the fact that the materials used for foaming have the property of foaming only in the direction of the plate thickness, but not in the longitudinal and transverse direction of the plate. But exactly this material behavior would be necessary to close the remaining free passages. However, such a material is not available. Another disadvantage is that

4 - 5 mm wide necessary slot in the transport rail, which causes increased wear and tear for the operation of the transport system.

- - conditional reasons are equipped with a simple linear-acting spiral tension spring as a closing element, which, due to its operating characteristics, does not allow closing from all positions, in particular intermediate positions, into the exact end position of the sealing element. As fire tests show, in the event of a fire, it is of crucial importance whether the movable sealing element reaches the exact end position or not.

The known fire protection closures are equipped with a drive system in the form of toothed racks, chains or guide rods, in which the drive motor engages directly, the outlet of the drive motor after switching off via the limit switch and the position of the sealing element in the closed state certainly. As in the betrieb¬ union practice current and voltage fluctuations un ^¬ are preventable, shows the drive motor different leak paths. Consequently, for this reason, an exact compliance with the Endstel¬ development of the sealing element with this drive system does not ^"accurately determined.

- The known fire protection closures have to be installed on the construction site after a complicated and therefore complex assembly process, in which the subsequent safety for guaranteeing fire protection depends to a very decisive extent on the manual skills and the current, very different possibilities of Fitter depends on the construction site. Taking into account the fact that fire protection barriers generally have to be installed either in narrow lift shafts or in hard-to-reach places on walls and ceilings, this poses a considerable security risk, above all visible that any assembly errors during the building inspection can no longer be determined. These would only show up in the event of a fire and thus have a disastrous effect.

- The known fire barriers, in which a separated component of the transport rails is fastened to the slide element, cannot give the necessary support for proper transport operation in relation to the forces acting on the transport goods. In addition, the required exact end position of the separated component of the transport rail in the normal transport position cannot be guaranteed with the linearly operating drive technology used.

- Although the European patent application with the publication number 0033126 is known, in which a technical solution idea is described which deals with the problem of moving out rail parts. The technical proposals made therein already point to certain possible solutions, but generally assume that a movable rail part is attached to a slide-like sealing element and, together with this, completely moves out of the opening during the closing process becomes. The movable rail part is thus in the region in which the sealing element overlaps the opening when the fire protection closure is closed, which causes considerable sealing problems. Practice has proven that constructions based on this solution concept cannot be realized.

The invention ^'is therefore the object zu¬ round as Bereicherun of the prior art to create a further fire protection closure in which the present position can be solved with simpler technical means and which takes up much less space in the area around the opening.

The object is achieved in the invention in that

Metal profiles, preferably angle profiles, form an outer circumferential surrounding frame into which the insulating sealing frame made of fire protection plates with the circumferentially inserted sealing lips is fastened by means of a screw connection in such a way that the overlap (a) occurs as planned,

- The intermediate frame made of fire protection plates, which is framed by a metal frame, can be moved at a regular distance (f) from the insulating sealing frame via precision running rails. "" is connected to the outer frame, thereby making it parallel. can be moved without contact to the insulating sealing frame,

- The intermediate frame is dimensioned so much larger in its outer dimensions than the clear width of the opening that the various overlaps (b), (c) and (d) are created as planned, the overlap (d) depending is dimensioned by the different height dimension (e) of the transport rail, furthermore the clear width of its inner cutout, which corresponds to the clear width of the opening, and in the area of the overlap (b) of the sealing lips inserted and protruding in the insulating sealing frame suitable sealing groove for the penetration depth (e) are incorporated, so that at all points the distance (f) is planned,

- the rimmed with a metal frame Dichtele¬ ment of fire-protection plates so by strong hinges to the outer perimetrical ver¬ prevented is that it, by 90 ° is pivotable about the pivot point, with its longitudinal axis parallel to the fire section separator to 180 ^9, the same width as the intermediate frame has, but is dimensioned in height so that it can be freely pivoted over the fixed transport rail, but at the same time, at least the overlaps (q) and (h) occur when the fire protection closure is closed,

- The separated section of the transport rail is fastened on the inside of the inner cutout of the intermediate frame running transversely to the direction of transport to a console especially suitable for load-carrying and thus during the closing operation in the direction of movement (82) together with the intermediate frame from the Rail assembly of the transport rail is moved out by the lifting movement (i) in the direction of the center of the opening (10),

- The lifting movement (i) of the entire intermediate frame including the separated section fastened in it is actuated in both directions by a door-closer (38) via a positively guided and thus positively-controlled drive unit and actuated by the door closer (38) and via the pivot point by 90 ° to 180 ° pivotable sealing element, which consists of a guide rail fastened to the lower part of the intermediate frame, one therein Drive lever I can be swiveled 0 ° to 180 ° and either a reversing gear with three shaft ends and a pair of bevel gears or a bearing block (83) with a continuous shaft, a drive lever III fixedly arranged thereon, the connecting rod provided with ball joints and the one on the Axle attached drive lever IV is, whereby the. Connection to the axis mounted in the fulcrum is established. which is in turn firmly connected to the pivotable sealing element via the hinges, so that the pivoting movement of the sealing element inevitably leads to the lifting movement (i) from the intermediate frame or vice versa, or ^•

- The lifting movement (i) of the entire intermediate frame via drives which are independent of the pivotable sealing element, but not shown in the drawing, such as energy accumulators in the form of tension springs or counterweights, or movement elements in the form of electrical lifting magnets or rotating magnets, pneumatic or hydraulic actuating cylinders or ei¬ nes electric motor with a reduction gear attached, and

- That a drive is provided, which acts either on the free shaft end of the reversing gear, on the drive lever I, on the pivotable axis or on the sealing element.

In a further embodiment and for the purpose of automatic operation, the object is achieved with the invention in that

- The drive lever II, which executes the pivoting movement of preferably 90 °, is fastened to the free shaft end of the deflection gear, with this pivoting movement of the drive lever II via the deflection gear, the coherent and coordinated movements of the drive lever I, the intermediate frame and the axis of the sealing element described in patent claim I are forcibly carried out,

the pivoting movement of the drive lever II itself takes place in both directions via a positively guided and thus with a positively controlled connection unit which consists of the drive lever II, the drive rod I, which is adjustable in length by means of a thread in a ball head, including a transverse bolt, the drive rod II, which is firmly inserted in the end for the calculated path (k) of the transverse bolt, elongated guide is incorporated, the lever arm, the locking device, the separable locking system (eg holding magnet), the lever arm, the drive device, the gear mechanism and the drive motor exists, whereby the connection to the drive unit deflection gear is established,

the length of the elongated guide machined in the drive rod II is such that the pivoting path of the driving lever II, preferably 90 °, and the pivoting path (62) of the rotation around the pivot bolt are determined by the displacement path (k) of the transverse bolt defined therewith The point of the pivotable lever arm is 90 ° plus x °, where x ° corresponds to the size which is necessary to move the cam disc, which is arranged on the same pivot point and is fixedly connected to the lever arm via a shaft, in a mode of operation of the Only pivot the drive so far in the opening direction that the lifting rod is raised in the direction of movement by means of a roller so that the de- NEN locking bolt locked sealing element is unlocked from this holding position and can thus pivot freely when opened by the pivoting movement of the drive lever II,

- A drive device is arranged on a support arm, in which a lever arm pivotable on a shaft / axis of the locking device by a certain number of degrees, from which the connection to the connecting unit is made, via the separable locking system acting as a driver from that on the same axis alignment mounted lever arm, which is connected to the drive motor via a gear transmission, ^*

- The closing device is arranged so that the pivotable lever arm, when it is released by separating the hold-open system, has reached its closing direction that it automatically strives for when the pivotable sealing element stands in front of the opening and seals it as planned, the drive lever II is in the closed position,

a commercially available mechanical-hydraulic door closer is used as the locking device, the closing energy of which is generated by the drive motor with each pivoting movement of the lever and from position to position,

- The lever arm thus preloaded in position is held there by the separable locking system connected to a fire monitoring system (not shown in the drawing), a holding magnet as the locking system and, if none

Drive motor is used, the lever arm is preloaded by hand and the gene plate of the hold-open system is attached to the frame of the fire protection closure,

- On the outer peripheral frame on the console is arranged in the direction of movement telescopically operating drive device, the extendable drive rod on the pivotally mounted about the pivot point of the axis and z. B. is articulated via a welding point firmly connected to the swivel lever drive lever V,

- On the swivel lever (lol) the separable and acting as a hold-open device is arranged so that the swivel lever is connected to the swivel sealing element, whereby the drive separation (102) is created.

- Mounted on the outer frame of the door closer, the pivotable locking lever at the upper end of the drain roller, which rolls in the guide rail attached to the sealing element and that the door closer has reached its closed position when the movable sealing element in front of the closing opening.

The advantages achieved by the invention are, in particular, that a fire protection closure for use with rail-bound transport systems is made available, with which openings in fire compartment partitions can be sealed and sealed in accordance with the regulations for standards-compliant constructions , which is easy and safe to transport, in which the assembly process is uncomplicated and safe, the regular function tests are easy to carry out, and low maintenance required, which has sufficient mechanical strength so that the movement-related number of movements is also achieved with a motor drive, the closing device of which ensures a precise end position of the movable sealing element in the closed state, which has an emergency closing device which mechanically closes the opening from any position, in particular intermediate position, of the movable sealing element, even in the event of a power failure and simultaneous fire, and which requires a small amount of space around the opening. The invention can advantageously be used for almost any type of transport system and can be used both horizontally and vertically.

The fire protection closure created in this way is fastened to the fire compartment separation "(11) by means of the fastening brackets (14) using fastening elements (70), usually metal expansion anchors Wall is also shown in Fig. 1 that the mass balance (45) via deflection rollers (44) and a roller chain (43) is connected to the intermediate frame (18). The roller chain (43) and the connections to the mass balance (45) and the intermediate frame (18) are dimensioned so that the full weight of the mass to be balanced can be absorbed even under direct fire over the entire period of the fire. The mass balance (45) is additionally accommodated in a protective tube, which, however, does not have to perform a fire protection task, is only attached for accident prevention measures. The sealing element (22) is connected to the axis (19) by means of a strong hinge (27) and can thus be pivoted in a bearing via the pivot point (20) into the pivoting region (21). The bevel gear (37) is attached to the underside of the axis (19) and represents the connection via the second bevel gear to the drive unit (23). Via the drive lever I (35), a positively guided connection to the intermediate frame ^' (18) is thus established via the connecting unit (23) by means of the drain roller (34) and the guide rail (33).

This creates a device in which the pivotable sealing element (22) acts as a drive for the lifting movement (17) of the intermediate frame (18). In the reverse sequence, the intermediate frame (18) can also act as a drive for the pivoting movement (21) of the sealing element (22).

In the non-motor-driven version, the drive device (59) and the connection unit (47) up to the drive lever II (46) are omitted. The closing operation is thus carried out by the energy-storing door closer (38), which is mechanically connected to the sealing element (22). In the open position, the sealing element (22) is replaced by a ^"" (not shown) Holding magnets of the fire monitoring system are held. In the event of a fire, the holding magnet is de-energized and releases the sealing element (22), as a result of which the door closer (38) comes into effect. In the closed position, locking takes place via the locking bolts (65). When the sealing element (22) is brought back into the open position, the door handle (73) is actuated by hand, as a result of which the locking bolts (65) are unlocked. With each opening and closing movement, the intermediate frame (18) with the screwed-on section of the transport rail (12) carries out the lifting movement with dimension (i). The stroke movement (i) depends on the length of the drive lever I (35) and its swivel path (40).

In the version with motor drive, the door closer (38) is omitted at this point and all movements are carried out by the drive device (59). Furthermore, the door handle (73) is omitted and the sealing element (22) is locked and unlocked via the locking bolts (65) by means of the lifting rod (66), which is actuated by the cam disk (64).

Fig. La shows the fire protection closure as explained in the description of Fig. 1, but in a modified form. The drive lever I (35) is fastened on the continuous shaft (84), which in turn is rotatably mounted in the bearing block (83). The drive lever III (87) is fastened on the outside of the bearing block (83) on the continuous shaft (84). This drive lever III (87), which can be pivoted by the same degree as the drive lever I (35), is connected to the drive lever IV (88) via the connecting rod (86) provided with ball joints (85) The axis (19) is connected to the sealing element (22) via hinges, so that the lifting movement (i) is forcibly carried out by the intermediate frame (18) with the pivoting movement of the sealing element (22) or vice versa.

Furthermore, FIG. 1 a shows the telescopic drive device (96), which is connected to the drive lever V (99), which in turn is firmly connected to the swivel lever (101) and, via the separable fixed device (57), onto the sealing element (22 ) works.

2 also shows the fire protection closure in the front view, but in the open position. The sealing element (22) is parallel to the transport direction. The intermediate frame (18) is lowered to its lower position, so that transport operation is possible via the separated section (29). In the version without a motor drive, the door closer (38) is in its pretensioned position and exerts a closing pressure on the sealing element (22). This is recorded by the Haftmagrieter not drawn. In the motor-driven version, the drive device is in the open position (81). The circumferential sealing lip (16) ^' can be seen in the intermediate frame (18), which engages in the sealing groove (41) of the sealing element (22) in the closed state.

Fig. 2a also shows the fire protection closure in the front view, but in the open position and in a modification of the description in Fig. 2. The sealing element (22) is parallel to the direction of transport, the movable part (90) of the intermediate frame (18th ) is at its lowest position '- 1 lowered so that transport operation is possible via the separated section (29). The fixed part (89) of the intermediate frame (18) is in its position. remained, thereby the free space 5 (m) was formed. The door closer (38) is in its pretensioned position and exerts a closing pressure on the sealing element (22). The drive rod (98) of the drive device (96) is in its extended position. 0

FIG. 3 shows a section along the line AA through FIG. 1 the fire protection closure in the closed state and shows how the fire protection system works. The intermediate frame (18) has moved upwards and the sealing element (22) has been pivoted in. The labyrinth seal between the sealing element (22) and intermediate frame (18) is produced with the aid of the sealing lips (16). The transport rail (12) is interrupted in the area of the separated section (29), the lower part of the intermediate frame (18) is inserted into this interruption. With the help of the overlaps (b), (g) and (h) the seal for the fire compartment separation (11) is created. The intermediate frame (18) and the separated section (29) of the transport rail (12) is shifted by the dimension (i). In the lower part of the drawing, the drive unit (23) is shown including the drive lever I (35), the deflection gear (36) and the axis (19). The upper section shows how the fire protection insulating plate (71) and the elastic seal (69) are used to carry out the step-by-step sealing. The same sealing system is used with the help of the fire protection insulation plate (72) on the lower part of the intermediate frame (18). Fig. 3a shows a section through Fig. La along the line DD. The fire protection closure is in the closed state. The movable part (90) of the intermediate frame (18) has moved upwards and abuts the fixed part (89) of the intermediate frame (18). The intermediate frame (18) is thus closed. The sealing element (22) is pivoted in, so that a circumferential overlap of the opening (10) in the fire compartment partition (119) is now ensured. The separated part (29) of the transport rail (12) is now in the region of the opening ( 10) The door closer (38) has reached its closed position.

Fig. 4 shows in a section along the line

B-B through Fig. 2 the fire protection closure in its open position. The insulating sealing frame (18) is moved into its lower position, the sealing element (22) is swung out. Transport operation takes place in this position, the separated section (29) being inserted into the gap between the two transport rails (12).

4a shows a section through FIG. 2a along the line E-E. The fire protection closure is in the open position. The movable part (90) of the intermediate frame (18) is moved into its lower position, which creates free space (m) for the fixed part (89) of the intermediate frame (18). The separated section (29) has thus moved into the gap in the transport rail (12) so that transport operation can take place. The sealing element (22) is pivoted out and is parallel to the transport direction.

5 shows in a section along the line CC through FIG. 1 the fire protection closure in the closed position. its state. The sealing element (22) moves on the web (21) into the open position. It pivots around the pivot point (20). The locking bolts (65) hold the fire protection closure in the closed position. By means of the lifting rod (66), the locking bolt (65) can be moved by the motor drive, so that the sealing element (22) is released for opening.

6 shows by means of the detail section I the mode of operation of the drive device (59) ". By means of the pivoting movement carried out by a motor drive (61) via the gear transmission (60). (62) of the lever arm (58) of the drive device is connected to the drive rod I ( 50), the transverse bolt (51) is firmly attached to the drive rod I (50). The upper part of the drive rod I (50) protrudes by a certain amount into the guide of the drive rod II (53) In this drive rod II (53) the elongated guide with the dimension (k) is worked in, in which the cross pin (51) can move linearly back and forth. This ensures that the lenear movement required to open the fire protection closure the drive rod I (50) by the lever arm (58) only takes place when the cam disk (64) fixedly attached to the same axis of the lever arm (58) has raised the lifting rod (66) to such an extent that the locking mechanism gelungsbolzen (65) the Have released sealing element (22) for opening. The idler roller (76) is attached to the lifting rod (66). This runs on the Ober¬ surface of the cam (64) ab.Eine such drive ^¬ device then always used when Fe ¬ erschutzabschlusse have to be moved by the drive. On the support arm, not shown, on which the locking device (55) is also located the axis (63) pivotable about a certain number of degrees driven lever arm (58) by means of a fixedly mounted on this lever arm separable Feststellanla¬ ge (57), which acts as a carrier, with the lucht in the same Achsenf ^'(63) pivotally (62) Arranged lever arm (54) of the closing device (55) is connected. The drive separation (56) is created by the drive device (59) thus created. The lever arm (58) which can be pivoted on the circular arc (62) is switched off in the two end positions by limit switches (not shown). The drive motor (61) with the reduction gear attached drives the shaft on the axle (63) with the lever arm (58) attached via the gears (60) and an adjustable torque clutch (not shown). The drive disconnect (56) is an essential and important feature in the operation of the present invention. It is necessary because the pivotable lever arm (58) can remain in the upper end position or in any conceivable intermediate position between the upper and lower end position as a result of a power failure or other disturbances. If a fire alarm occurs in such a case, the hold-open system (57) is separated by a smoke detector, the lever arm (54) pretensioned by the locking device (55) is released and the locking device (55) moves the lever arm (54) into the closed position ( 67). This system ensures that even in the event of a power failure it is ensured that the movable sealing element (22) is in front of the opening (10) in the event of a fire. The lever arms (54) and (58) moved together are indicated by dashed lines in the open position (68).

7 shows a detail II in an enlargement of the sealing system in the lateral area.

With the help of the mounting bracket (14) is the outer Enclosing frame (13) made of metal profiles attached to the fire section separation (11). The insulating sealing frame (15) made of fire protection insulating plates is fastened in the outer surrounding frame (13). From the end of the outer peripheral frame (13) to the front edge of the opening (10), the elastic seal (69) between the fire compartment partition (11) and the insulating sealing frame (15) is located in the space thus created. The sealing lips (16) are also embedded in the insulating sealing frame. These sealing lips protrude into the sealing groove (41) of the intermediate frame (18) provided for this purpose. The intermediate frame (18) is enclosed in a metal frame (26). The intermediate frame (18) is connected via this metal frame (26) to the outer surrounding frame (13) via the precision guide elements (25). As a result, the intermediate frame (18) can move at a distance (f) from the insulating sealing frame (15) parallel to the fire compartment separation (11). On the side opposite the sealing grooves (41) is the

Sealing lip (16) is arranged, which in turn protrudes into the sealing groove (41) in the sealing element (22). The sealing element (22) is. edged with the metal frame (28) and itself consists of fire protection insulating plates. The locking bolts (65) are firmly connected to the lifting rod (66) and hold the sealing element (22) pressed against the intermediate frame (18) in the closed state. For the purpose of special smoke sealing, the elastic sealing profile (42) is also attached in the area of the metal frame (26) of the intermediate frame (18). The inner cut-out (31) of the intermediate frame ^'(18) has the same size as the inside diameter of the opening (10) in the Brandab¬ separation cut (11).

Fig. 8 and 9 show attachment details for the (12) in variants, depending on the purpose of the transport system for the fire protection closure. is used.

Fig. 10 shows a detail section through Fig. La along the line G-G. In the area between the

Sealing grooves (16) have the cross-section-reducing bores (92) made along the line G-G. This reduction in cross section serves to reduce the heat flow.

Fig. 11 shows a detail section through Fig. 10 along the line G-G. The supporting console (32) is, for. B. ge by drilling out full material characterized by the bores (92) reduced in cross section. The reduction in cross-section must be calculated in terms of engineering so that, on the one hand, there is still sufficient static strength for the function of the bracket (32), but on the other hand, only so much residual cross-section should remain that 5 - 10% of the original amount of heat still flows.

It is important that this cross-sectional reduction is carried out approximately in the middle of the overlap area (b).

Fig. 12 shows in detail the arrangement of the telescopic drive device (96). The sealing element (22) is in the closed position in front of the opening. The bracket (97) is attached to the outer frame (13). The drive device (96) is pivotably attached to this console. On the opposite side, the drive device (96) is connected via the drive rod (98) to the drive lever V (99), which in turn is connected to the pivot lever (101), for. B. is firmly connected by the welding point (100). A unit which can be pivoted together is thus formed between the drive lever V (99) and the pivoting lever (101). On the outer end of the pivot lever (101) is the separable locking device (57), for. B. arranged a holding magnet. The counter plate of this holding magnet is fixed on the sealing element (22), so that the holding magnet and counter plate can act as drivers. The closing lever (103) of the door closer (38) is parallel to the fire compartment separation.

Fig. 13 shows the drive device (96) in the half-extended position. The drive rod (98) works in the direction of movement (95), the drive lever V (99) swivels about the pivot point (20). The pivot lever (101) performs the same movement. The sealing element (22) is also pivoted about the pivot point (20) via the locking device (57). The run-off roller (104) of the locking lever (103) of the door closer (38) rolls off in the guide rail (105), which is firmly attached to the sealing element (22). This forced operation makes the door closer (38). curious; excited. As a result of this pretensioning, the door closer (38) exerts a closing pressure on the sealing element (22) in the direction (94). In the event of a power failure for the drive device (96) and simultaneous fire alarm, which separates the locking device (57), the door closer (38) closes automatically via the closing lever (103) without the influence of external energy, by pulling the sealing element (22) over the pivot point (20) in the direction (94) in front of the opening (10) in the fire section (11).

14 shows the movement system as described above in the open position. Compared to FIG. 13, the drive rod (98) of the drive device (96) continues to move in the direction of movement (95). As described in FIG. 13, reached the open position. The door closer (38) is now in its final, prestressed position and exerts a closing pressure on the sealing element (22) in direction (94) via the closing lever (103). In the event of a fire alarm and a simultaneous power failure, the locking device (57) automatically disconnects. Due to the closing pressure of the door closer (38), the sealing element (22) moves on the web (102) in the direction of the fire compartment separation (11). The intermediate position (111) of the sealing element is intended to represent the movement sequence, which is shown in dashed lines. After the fire alarm has been cleared and the energy for the drive device (96) has been switched on again, the pivoting lever (101) is moved back to the starting position as shown in FIG. 12 via the movement of the drive rod (98). The live fixed device (57) is automatically coupled to the counter plate on the sealing element (22) and the entire movement system is ready for operation again.

The invention is not restricted to the exemplary embodiments shown and described. In particular - as shown alternatively in FIG. 3 - the sealing element (22) can be arranged offset by 9-0 ° and thus open and close via the movement path (112). An additional bevel gear drive (not shown) is required, which transmits the pivoting movement of the sealing element (22) to the drive lever I (35) in the manner described above. Furthermore, it is e.g. B. possible to use a modified, modified type in other transport systems. The invention also includes all fachmän¬ African modifications and further developments as well as partial _nd sub-structures of the described and / or illustrated features and measures.
