Abstract

The safety catch (10) has an L-shaped cross section and is laid flat over the upper edge of the inner door to extend over the gap between the two doors. The vertical flange of the is trimmed to a small width apart from an outer tag (160 to catch the outer door and an inner tag (15) to locate against the inside edge of the inner door. The catch swivels about a vertical axis (12) near the outer edge of the door. The safety catch guides the outer door into the correct closing position without jamming the two doors. The catch is sufficiently slim to fit into the space between the door and the frame and presents a slim fitting without disturbing the shape of the door.

Description

The invention relates to a two-leaf door, in particular fire or smoke protection door in Fully panic equipment with a door closing sequence device acting on both door leaves, preferably installed in the upper edge area of the door leaf, and with a two-armed Driver lever on the passive leaf about a parallel to the wing pivot axis extending axis of rotation is pivotally mounted, which is in the pivot plane extends with one end protruding from the passive wing to the active wing in the event of a panic swinging open of the passive leaf on the active leaf attacks this in advance, which is supported in the ready position with a stop formation on the passive leaf and when both door leaves pass under the action of the door closing follower pivoted into the door closing state when it stops on the active leaf and after passing of the active leaf is pivoted back into its position on the stop formation.

Two-part doors of this type are known, preferably in training as fire or Smoke protection doors, but also in other cases where there is an automatic closing the door arrives for other reasons or is desirable. It is a so-called Door closing device made use of that assigned to each of the door leaves comprises a door closer, which two door closers in dependence on each other working controlled that at the transition of the door from the open to the Always close the passive leaf in the closed position before the active leaf merges into this. This happens regularly in that the active wing in one The remaining swivel range is stopped before the closed position or is significantly delayed in this way, that the passive wing on the possibly leading wing in the The closed position is reached before the active leaf covers this remaining swivel path. Thereby the correct closed position is reached so that the impact bar of the passive leaf and that of the active wing or a central joint fold provided on the wing blades Take both door leaves between them.

Door closing devices are in the area of the upper edge of the door leaf and the Upper frame arranged, in a more elaborate design also in the upper edge area of the door leaves used that the visual impression of the door leaf leaves spared becomes.

Double-leaf doors of this type are primarily used in training as Fire or smoke protection door but also as a windscreen, burglar protection or the like a passage that serves as an escape route. The door is arranged so that it Belching by refugees swings open to the outside. In the event of a panic it is otherwise The usual consequence of opening the active wing first and afterwards, at least after the Fixed leaf no longer ensure, but it can be assumed that the fixed leaf is subjected to an impact force in front of the active leaf. But then there is a risk that the mutually facing end faces of the two tufted leaves collide and that intends to quickly open the door. In full panic gear is such a door therefore beyond the door closing follower device with a driver lever equipped, in the event of a swing-out force first exerted on the passive leaf from this takes the active wing in such a way that it moves simultaneously and preferably is opened increasingly prematurely until the wings are no longer mutual Subject to disability. Since it must be ensured when swiveling back into the closed position must ensure that the passive leaf comes first and only then the active leaf into the closed position, If necessary, the passive leaf must be attached to the closing follower for this purpose stopped or braked active wings can be moved past, why the driver lever when pivoting the passive leaf in the closed position and Passing past the active wing in turn is pivoted by attack on it, until the passive leaf is advanced sufficiently into the closed position that the driver lever freed from his attack on the active wing into his standby position on the Inactive leaf can pivot back, whereupon only the active leaf the rest of the pivoting movement executes in the closed position.

Such driving levers are in the previous version via a fitting element on the the broadside of the passive leaf facing the escape route, that is to say viewed in the direction of escape arranged and grip with a roller on the one pointing in the same direction Broad surface of the active leaf. This creates the aesthetic appearance of the door leaf seen from this direction impaired, veneered doors also result ugly pressure paths of the roller track.

The invention has for its object a door of the type mentioned in her improve visual appearance.

This is achieved according to the invention in that the driver lever on the upper edge the door leaf arranged and in view of the small air gap between the upper edge of the door leaf and corresponding to the upper frame spar, which runs parallel in the closed state is flat.

The flat driver lever appears practically not seen in the direction of escape more in the field of view of the viewer on the broad side of the door, since he is in the gap between the Door leaves and their top edge to the neighboring horizontal frame practically not What seems more disturbing is what also applies to the other broad side of the door, especially when this is provided with a fold covering this joint. The one to the top edge of the door leaf Flat-running driver levers could be a little in this upper edge be let in, in a preferred embodiment, however, it runs entirely immediately adjacent to this upper edge in the joint between this and the neighboring horizontal Zargenholm. The perpendicular to the axis direction of the pivot axes of the door leaves The axis of rotation of the driving lever could be slightly above the upper edge of the passive leaf arranged in the direction of the active leaf and by a supporting part be held, in a particularly preferred embodiment, this axis of rotation of the driving lever however arranged in the passive leaf itself, preferably in a shaft-shaped Element held that from the top edge of the leaf in the interior is stored.

The end of the two-armed driving lever facing away from the active leaf is preferred Version with a downward protruding projection that is in the ready position of the driver lever in the upper edge area, the one that swings open in the event of panic Exposed broadside of the passive leaf is supported. For the case that the broad side of the door leaf pointing in the pivoting direction with a If the fold protrudes upwards, this can support the driver lever can also be provided on the inside of this fold in the ready position.

In a further preferred embodiment, the end area of the active wing facing the two-armed driver lever with a downward protruding shoulder, that as a driver training in the upper edge area of the retreating when swinging open Attacks the broad side of the active leaf and swivels the active leaf in the direction of opening, if the passive wing is pushed open in front of the active wing in the event of panic. Here too If the door is folded accordingly, an attack on the inside of the fold is possible, if the required stability is given.

In another preferred embodiment, the start-up shoulder is in the attack area at the edge area formed on the broad side of the active leaf and / or this Edge area equipped with a strip-shaped attack track, which the friction on the Start-up shoulder is reduced and is resistant to this friction.

Enable the design of the driver lever with a projection and a starting shoulder its manufacture from an angle profile, which is basically made of plastic, preferably but made of steel or stainless steel and, depending on the arrangement, unchanged in this form can form the driver lever. Depending on the structural conditions, weight considerations and the like. In a preferred embodiment, the leg formation between the projection and Start-up shoulder removed.

The driver lever is in the position to ensure that it is in the ready position the projection rests as a stop formation on the edge area of the passive leaf and thus the toggle lever in the closed position of the door in the direction of the successive The upper edges of the door leaves are spring-loaded, which is done in many ways can. In the sense of an undisturbed appearance of the door, one intervenes corresponding spring preferably received in the shaft-shaped element on the Axis of rotation of the lever or the lever itself and is at the other end on the door leaf supported itself or the element; such a spring is preferably a spiral or Torsion spring formed.

To advance the active leaf in the event of the panic-induced opening of the passive leaf ensure, depending on the position of the axis of rotation facing the active wing or on this attacking lever arm of the driver lever be longer than the opposite lever arm striving from the axis of rotation, which is supported on the passive leaf.

The invention is explained in more detail below with reference to the embodiment shown in the drawing. Show it:

Figure 1

in a schematic representation, two top views of a two-leaf door, one in the position when swung open by attacking the passive leaf and the other in the course of an end angle range of the pivoting into the closed state;

Figure 2

a perspective view limited to the upper free corner area of the passive leaf together with driving lever;

Figure 3

a vertical, perpendicular to the broad section seen at the location of the axis of rotation of the driving lever through the passive leaf.

Figure 1 shows in two representations the active leaf 1 and the passive leaf 2 with the active leaf 3 and the passive leaf 4, the active leaf equipped with a lever handle set 7 and the passive leaf with the driving lever 10, which can be rotated parallel to the Swivel axes of the hinges 5 extending axis of rotation 12. The picture above shows that Swinging open the two door wings symbolized by the corresponding arrows from the Closing in the open position, whereby in the event of a panic it is assumed that the opening force is introduced into the passive leaf. In a manner described in more detail later is the driving lever 10 in its pivoting position about the axis of rotation 12 in the drawn position by a stop on the edge area when swiveling retreating broadside 19 of the fixed leaf 4 is held and engages with its start-up shoulder 16 to the lateral edge area of the receding in the pivoting direction Broadside 18 of the active leaf 3, whereby the active leaf 1 with respect to its pivoting movement is taken along by pivoting the passive leaf 2. This happens increasingly prematurely from the closed position, as the figure shows. The thrust shoulder 16 of the driving lever 10 slidably engages in the edge region of the Broadside 18 of the active leaf 3, this sliding attack by appropriately rounded Training the starting shoulder 16 and / or the affected edge area is carefully designed.

The lower illustration shows the door leaf 1 and 2 in the phase of pivoting in the closed position, in which the active leaf 1 by the door closing follower device, not shown is braked or stopped with respect to its swiveling, while the Inactive leaf 2 - so far lagging - in the direction of the arrow there with regard to it the end face 9 facing the active leaf 1 is guided past the end side 8 of the active leaf 1 is, the longer lever arm 13 of the driving lever facing the active leaf 1 10 strikes on the end face area of the active leaf 1 and about its axis of rotation 12 pivoted against the low restoring force of a spring, whereby the stop of the shorter lever arm 14 on the edge region of the broad side 19 of the Leaf 4 stands out. After passing the passive leaf 2 on the active leaf 1 so far over that the lever arm 13 of the driving lever 10 out of engagement with the end face region of the active leaf 1 arrives, the driver lever 10 pivots under the stored one Force of the spring, not shown, back to its ready position, in the the shorter lever arm 14 in contact with the edge region of the broad side 19 of the passive leaf 2 reached. After the transition to the fully closed state, the door is ready to be opened ready in case of panic. The pivot position of the driving lever 10 in the lower Representation - transition to the closed position of the door - is with regard to the pivoting position reproduced schematically.

The partial representation on the upper corner area of the angel facing away from the associated Part of the passive leaf 2 shows the arrangement of the flat driver lever 10 in the Provision position in which the flat part of the driving lever 10 is immediately adjacent runs parallel to the upper edge 11 of the leaf 4 and is straight over the closing joint between the door leaves in the closed position into the area extends above the upper edge 21 (Figure 1) of the non-illustrated active leaf. The driver lever 10 is pivotally mounted about an axis of rotation 12, which in the present case Figure 3 - is held in a shaft-shaped element 17 which from the upper edge 11 of the Inactive leaf 4 seen parallel to the pivot axis of the hinges 5 - Figure 1 - in the Interior of the leaf 4 is inserted engaging. The axis of rotation 12 with element 17 is arranged near the end face 9 of the passive leaf 4 facing the active leaf 1.

The driver lever 10 is in the end region of its shorter, assigned to the passive leaf 2 Lever arm 14 is provided with a lateral projection 15 which projects downwards and into the illustrated, by acting on a arranged in the region of the axis of rotation 12, Not shown spring on the upper edge region of the broad side 19 of the leaf of the passive leaf 4 is present, against which the refugee's opening force acts in the event of panic, and is thus in the standby position in preparation for the panic case. In from the End region facing away from the axis of rotation 12 and projecting in the direction of the active leaf 1 Lever arm 13 of the driving lever 10 projects laterally downwards in the same way a starting shoulder 16 bent, which - as described in connection with Figure 1 - the attack on the upper edge area on the same side as the broad side 19 Broadside 18 of the active leaf 3 is used if the inactive leaf earlier in the event of panic when the active wing is acted on.

The design of the door shown is with one over the end face 9 of the leaf 4 protruding blow bar 20 provided, while on the opposite side of the Active leaf has a rabbet projection - Figure 1 - in such a way that when the door is closed the middle joint gap between the facing end faces of the door leaves on both Door broad sides is covered. Otherwise, the door can go up with a total protruding fold 22 may be provided.

The driver lever 10 shown in perspective in FIG. 2 with its downward protruding bends - projection 15 and starting shoulder 16 - can be manufactured simply gain from a section of a right angle profile in which one the leg area of the angle profile between the projection 15 and the start-up shoulder 16 removed.

Figure 3 shows a section through the corner area according to Figure 2 vertically and perpendicular to the broad sides of the passive leaf 4 through the axis of rotation 12 of the driving lever 10 in association with the upper frame spar 23 of the neighboring frame area. The not Driver lever shown in section runs flat and closely adjacent to the upper edge 11 of the passive leaf 4 in the between this surface and that in the closed state Adjacent wall of the upper frame beam 23 formed air gap 25th The projection 15 and the start-up shoulder 16 face a stop seal 24 or press on this, which in a corresponding stop area of the upper frame spar 23 is formed.

As can be seen in particular in Figure 3, the entire driver lever occurs particularly in the closed door condition on the wide areas of the door does not appear and enables therefore a visually appealing, for example with uninterrupted veneer provided design of the broad sides of the door.
