Abstract

A two-leaf door has a fixed leaf (2) and a through-passage leaf (3) one after the other in the aforementioned order by a door-closing-sequence-control device, in order that closure is ensured and that collision of the rebate overlapping portions (7, 8) on the end sides is avoided. In order that, when the fixed leaf (2) is opened, e.g. in an emergency situation, the through-passage leaf (3) is likewise pushed open at least to the extent where the closing sequence can be ensured, the upper rebate (9) of the fixed leaf (2) contains a driver (10) which has a flat rail (11), projecting beyond the end edge of the fixed leaf (2), and, at the front end of the flat rail, a pivotable lever (12), which projects even further. The driver (10) engages in the upper rebate (15) of the through-passage leaf (3). The overlapping portion of the rebate (15) or (7) is reinforced by a metallic cover (21). The flap rail (11) has a bore for a locking means (4) and a depression (16) for the insertion of a guide plate (17). The lever (12) can be pivoted on the flat rail (11), counter to the spring force, in the direction of rotation of the fixed leaf (2).

Description

PICKERS FOR MOUNTING IN THE UPPER DOOR OF A DOUBLE LEAF DOOR

Technisches GebietTechnical area

The invention relates to a driver for mounting in the upper door rebate of a standing wing of a two-leaf door, in particular a fire or smoke protection door with full panic equipment and with an attacking on the wing and an associated wing door Schließgestgestereinrichtung, which at a self-closing first the wing and then only the wing moved into the closed position, wherein the driver protrudes beyond the end face of the vertical door rebate of the upright wing and urges the heel on opening the upright wing and swings back when closing by the Türschließfolgesteuereinrichtung of the end face of the retained wing against spring force.

Stand der TechnikState of the art

Two-leaf doors in fire and smoke protection design with panic function must be equipped so that they close automatically after any panic-like leaving the rooms. It should indeed be ensured that no oxygen is introduced into the building interior and that the fire is limited to the interior and is deleted by automatic systems there. However, this automatic closing of the double-leaf door can be a problem when the wing closes first, because the wing then struck on the rollover of the door rebate of the already closed wing and a door gap remains open. To prevent this, door lock controllers are known. If, for example, in the event of panic both the wing and the leaf have been pushed open, all these devices ensure that the leaf will remain in a slightly open position (for example 30 ° opening angle) when it closes automatically to allow the closing wing to pass first to reach the closed position. Then follows the pedestrian wing. It can close collision-free, with the wing flap folding sealingly into the complementary vertical wing fold.

This locking system with the door-closing control device according to the above functional description presupposes that the aerofoil has been opened at least as far (ie, for example 30 °), that the waiting position for advancing the standing wing has been reached. If, for example, in the case of panic only the wing is pushed open, then the case could occur that it strikes against the rollover during closing despite the door-closing control device lacking a sufficient opening angle of the pusher and thus a tight closing of the two-part door is not guaranteed. This problem has already been identified and therefore describes the

a driver, which is mounted on the wing and the foot when opening the wing so far that the waiting position (eg 30 ° opening angle) of the pusher is reached and thus the door closing sequence (first closes the wing and then only the sash) guaranteed is. For this purpose, a driving lever is pivotally mounted in the upper fold of the upright wing, which projects beyond the front edge of the upright wing and engages in the fold of the pusher. A run-up shoulder of the driving lever visibly emerges from the fold, is visibly attached to the door surface of the pusher and takes this one piece as soon as the wing is opened. It is thus ensured that the active leaf is correspondingly wide open in order to allow the self-closing of the upright wing this collide on the wings without collision. Thus, the far overhanging catch lever does not collide with the walking leaf when closing the upright wing, it is - as described - rotatably mounted in the rebate of the upright wing. So he can swing back when closing and in contact with the waiting in the wings to pass the wing at the wing. Apart from the visible start shoulder and another visible stop there is the serious disadvantage that a vertical wing lock up is not possible, because the pivoting cam lever would collide with the bolt.

Darstellung der ErfindungPresentation of the invention

The invention aims to provide a solution to this problem with simultaneously completely concealed arrangement with closed double-leaf door.

This is achieved in that the driver has a flat rail, which is rigidly screwed into the upper door rabbet and as a rigid component, the front of the upright wing to the leaf out beyond that hinged at the free end of the flat rail, a lever in the plane or parallel plane of the flat rail is and that the angle of rotation is limited by the extended position in continuation of the flat rail starting on a rotational direction corresponding to the direction of rotation of the upright wing. As a result of the pitch of the driver in a rigid recessed in the groove recessed flat rail and in a rotatably hinged in the cantilever lever are no moving components in the fold. Thus, no additional area must be milled out in the fold, in order to allow there to pivot. Also, there may be no collisions with an upper floor wing latch lack of pivoting in the fold. This can easily enforce the flat rail.

It is useful if a stop for the pivoting range of the lever is provided on the flat rail to which the lever rests in its extended position in continuation of the flat rail and prevents pivoting of the one-armed lever against the opening movement of the upright wing, but releases in the opening direction. The stop is immediately part of the driver construction and a vote on the door leaf thickness, as in the case of the aforementioned

, not necessary.

The assembly of the driver may be formed in such a way that the lever is biased by spring force against deflections from the extended position relative to the flat rail. It is not necessary to mount several construction elements independently of each other.

The design is such that it can be used with any wing-door lock. For this purpose, the flat rail has a bore for the passage of a bolt of the lock for the upright wing in the door frame.

A specific embodiment is characterized in that a recess in the region of the bore for receiving a guide plate for the locking is provided in the flat rail and that the recess has further holes for screwing the guide plate in the fold. The recess may be matched in their dimensions to common guide plates for the bolt on push rods or the like.

In order to arm the contact area of the driver, namely the lever in continuation of the flat rail on the inside of the supernatant in the fold, it is advantageous if the rear wing in the contact area of the driver inside the rollover of the fold and the front side a support, in particular a metal angle to Reduces friction and reduces wear.

Kurze Beschreibung der ZeichnungenBrief description of the drawings

An embodiment of the subject invention is shown in the drawings. Fig. 1 shows a two-leaf door with wings and wings in the closed state from above; 2 shows a driver when opening the upright wing in the driver function. and FIG. 3 shows the driver during automatic closing in passing the upright wing on the wing which is initially waiting in a sufficiently open position due to the door closing control.

Bester Weg zur Ausführung der ErfindungBest way to carry out the invention

According to FIG. 1, a two-leaf door with a standing wing 2 and a footer 3 is provided in a door frame 1. The standing wing 2 is provided with a lock 4 for the door frame 1 and has a handle 5 (for example a handle bar) for unlocking and pressing the standing wing 2. The aerofoil 3 is equipped with a standard handle set 6 for a latch lock or the like. Not shown is a door-closing control device approximately in the form of two door closers, which engage the upright wing 2 and on the aerofoil 3. They ensure that the e.g. in the event of a panic, standing and

active wings

2 and 3 are automatically closed for reasons of fire protection - with the special feature that the active leaf 3, before reaching the closed position, is closed in an open position of e.g. 30 ° remains and waits ("waiting position") until the wing 2 has passed and closed. If this is not the case, then there would be a collision on the basis of the front door rabbets 7 and 8. To ensure that when pressing the upright wing 2 of the rotary wing 3 is at least so far taken that the above Waiting position (eg 30 ° opening angle) is reached, the upright wing carries in its upper fold 9 in a dimensionally accurate cut a driver 10. This includes a rigidly bolted to the upright 2 in the fold 9 flat rail 11, which projects beyond the frontal fold 8. At the free end of the flat rail 11, a lever 12 is pivoted to its extension. A pin 13 forms a stop and ensures that the lever 12 can only be rotated in the direction of rotation of the upright wing 2. Due to a spring in the pivot bearing 14, the lever 12 is biased toward the extended position shown in Fig. 1, so that the lever 12 rests against the pin 13 under spring force. As can be seen from Fig. 1, the driver 10 engages deep in the upper fold 15 of the pusher 3 a. The driver 10 is arranged completely hidden and not visible from the outside or from the room side.

The lock 4, namely a locking pin, engages through the flat rail 11. For this purpose, a recess 16 is provided in the illustrated embodiment in the flat rail 11, in which a guide plate 17 is inserted for the lock 4 and secured by two screws through

holes

18, 19 in the flat rail 11 in the upper fold 9 of the upright wing 2. An adaptation to different bolt cross sections or diameter is possible.

2 shows only the frontal regions of the upright wing 2 and the rotary wing 3. The upright wing 2 has been unlocked by actuation of the handle 5 (for example a horizontal grip rod) and pushed open in the direction of the arrow 20. The lever 12 of the driver 10 slides with its rounding along a support 21 made of metal and opens the pedestrian wing 3. The lever 12 can not retreat, because it rests against the pin 13. As a result, the leaf 3 is pressed by the driver 10 so far that the waiting position in the context of Türschließfolgesteuerung (ie 30 ° opening angle) is reached and thus the automatic closing the closing sequence (first closes the wings 2 and then only the wings. 3 ) is complied with.

Fig. 3 shows the automatic closing of the open wing 2 in the direction of arrow 22 on the open, waiting wing 3 over. The lever 12 abuts on the aerofoil 3, namely on the armor 21 reinforced by the overlap of the front-side fold 7 and deviates back against spring force in the manner of a spring detent. The flat rail 11 has a projecting length, which can happen without collision. Thus, the upright wing 2 reaches its closed position in which the lock 4 projects automatically and fixes the upright wing 2. Only then is released by the door closing control of the pedestrian wing from its waiting position and brought into the closed position.
