A controller proper (6) actuated by the transmission sits on the closer (2b) of one leaf (1b) and has a member (61) which contacts the transmission member while the door is being closed, being actuated dependent on the position of the transmission. The controller proper controls a lock. Preferably, the member is adjacent to the transmission at small door opening angles and is remote from it when the door is open more widely.

Description

The invention relates to a device for regulating the closing sequence of two-leaf Doors with one that cooperates with an overhead closer Inactive leaf and one with an overhead closer and a blocking device interacting active leaf, with a controlling the blocking device Control device, with one connected to the passive leaf or a Part interacting actuator and the actuator with the control device connecting transmission link.

Such a closing sequence control is e.g. B. in doors with an embezzling and an overlapping wing is required. Only if the embezzling Inactive leaf before the overlap active leaf comes into the closed position ensures the proper closing of the door.

From DE-OS 34 06 433 is a two-leaf door with such a closing sequence control known. The correct closing sequence is realized in that the Active leaf via a valve in the hydraulic circuit of the active door closer blocked for a long time until the passive leaf is closed.

From DE-OS 33 29 543 a similar device is known in which the Active leaf is blocked by a device on the door closer linkage. Also this blocking device is operated with a Bowden cable operated by the passive leaf driven.

Furthermore, e.g. from DE-OS 38 00 694 and DE-OS 36 04 091 similar Arrangements with sliding arm door closers known in which to block the Active leaf The sliding arm of the active door closer is blocked until the inactive leaf is in the closed position. The blocking device of the active leaf is controlled by a control device, which one with the sliding arm of the passive leaf closer cooperating actuator and a Bowden cable that connects the actuator to the blocking device.

In all of the above-mentioned embodiments, part of the Bowden cable is freely visible and freely accessible from the outside. As a rule, this is the partial route, in which the Bowden cable from the door frame to the door closer of the active leaf to be led.

The object of the invention is a closing sequence control for double-leaf doors develop which is reliable and a visually appealing design having.

The object is achieved with the subject matter of patent claim 1.

The transmission link is in the area of the door frame between two positions movably arranged, the switching positions by the two positions the control device can be defined. The control device is on the door closer of the active leaf preferably on the closer spring mounted on the door leaf Receiving door closer housing arranged and has a control member preferably control lever, which is only in the course of the closing process of The active leaf comes into active contact with the transmission element, the control element is operated according to the defined switching position. Preferably when the control member is actuated, the blocking device for determining the Active wing triggered or canceled.

The control member can be designed as a preferably pivotable control lever his. The starting position of the control lever can be in a 180 ° Range can be variably adjustable.

The length of the control lever is preferably variably adjustable or changeable.

Characterized in that the control element only in operative connection in the course of the closing process with the transmission link, there are new design options. In a preferred embodiment, the transmission link is a profile preferably formed cover profile, which extends across the entire door width extends and is slidably mounted between two side caps. By a return spring, which is arranged in one of the cover caps acted on the cover profile in the direction of a first switching position. In this as Switch position designated locking position, the control lever runs when closing of the active leaf on the cover profile, whereby it is deflected and thereby a locking device arranged in the moving door closer for locking of the active leaf operated.

In preferred embodiments, it is provided that the cover profile is L-shaped a horizontal leg and a vertical leg is formed, wherein the height of the vertical leg preferably corresponds to the height of the rails, in which one from the closer of the passive wing or the active wing driven closer arm is guided with a slider or the like. The vertical leg of the cover profile can be in a common plane with the Front surface of the door closer housing lie and cover the rails, whereby the horizontal leg of the cover profile connects to the rails. The vertical legs of the cover profile can have a convex shape.

The actuator can be motion-coupled to the transmission element. Preferably it is provided that the actuator is L-shaped with a horizontal Leg and a vertical leg is formed, the vertical Leg is connected to the vertical leg of the cover profile and the horizontal Leg connects below the rails to the door frame.

Furthermore, the cover profile has a gap for receiving the control lever. The second switching position of the cover profile, which is called the release position is defined by the fact that the recess when closing the active leaf aligned with the control lever. In this way, the active leaf can close by moving the control lever into the gap without being operated.

The closing sequence control is ensured in that the passive leaf in Closed position on a slide rail arranged in the area of the passive leaf and acts on the actuator connected to the cover profile. With the passive leaf open the cover profile is in the locked position under the action of the return spring. A tapered active leaf meets the cover profile and with the control lever is determined until the inactive leaf has reached its closed position. In In the closed position, the passive leaf actuates the actuator, whereupon the cover profile in the Release position shifted and the blocking of the active leaf released becomes.

In Figure 1 , a two-leaf door 1 is shown with a closing sequence control according to the invention. The door 1 has two stop door leaves 1a and 1b. The right wing 1a in FIG. 1 is articulated on its right vertical edge via two bands 12 on the right vertical spar of the door frame 11. In a corresponding manner, the left wing 1b is articulated on its left edge via two bands 12 on the left frame spar 11.

The right wing 1a has a stop web 13 on which the overturning Rebate web 14 of the left wing 1b in the closed state of the door 1 invests. This makes it necessary to close the door 1 first right wing 1a - the so-called passive wing - and then the left wing 1b - the so-called active leaf - comes into the closed position. Of course you can in other versions also the left wing as the passive wing and the right wing Wing can be designed as a moving wing. On the fixed leaf 1a there is an overhead one Door closer 2a attached, the closer shaft 3a with a closer arm 31a is connected. The closer arm 31a is in an on the upper horizontal spar of the door frame 11 attached slide rail 4a guided by the arm 31a with a slider 41a articulated at its free end, which also can be designed as a roller, engages in the rail 4a. In corresponding The active leaf 1b is also provided with an overhead door closer 2b, the closer arm 31b connected to the closer shaft 3b in the Rail 4b is guided.

On the upper horizontal frame 11, a cover profile 5 extends over the entire Width of the door 1 and covers both slide rails 4a and 4b. The Cover profile 5 is between two side caps 51 in the horizontal direction slidably mounted. The two cover caps 51 are stationary on the frame 11 attached. The two end positions of the cover profile 5 make two Switch positions for actuating a control device 6 defined. The one on the active wing door closer 2b arranged control device 6 has a vertically the control housing 61 protruding control lever 61. The control lever 61 serves to determine the active leaf 1b when the passive leaf 1a and controls for this purpose a blocking device arranged in the active leaf door closer 2b. The blocking device can be, for example, a Act the valve in the hydraulic circuit of the leaf door closer 2b.

A first switching position of the cover profile 5 is a locked position, in which a control lever 61 assigned to the control device 6 at Closing the active leaf 1b on the cover profile 5 and thereby the Active leaf door closer 2b associated blocking device for determining the Active leaf 2b actuated. In a second, referred to as the release position Control position 61 is aligned with the closing of the active leaf 1b a gap 55 arranged in the cover profile 5, so that the active leaf 1b without Operation of the control lever 61 can close.

The cover profile 5 is arranged by a cover cap 51 in the passive leaf side Return spring 54 is applied in the direction of the locking position. Is to one end of the spring 54 at the outer end of the passive leaf cover 51 attached and the other end of the spring 54 at the right-hand end of the cover profile 5. Under the action of the return spring 54, the cover profile 5 at opened passive leaf 1a pulled to the right into the locked position so that the Active leaf 1b before reaching the closed position by operating the control lever 61 is determined on the cover profile 5. When the inactive leaf 1a is closed, the Glider 4a of the passive leaf 1a with one between the two rails 4a, 4b arranged actuator 52 together, whereby the cover profile 5 in its release position is moved, and the active leaf 1b can close completely.

Figure 2 shows an enlarged perspective view of the active leaf door closer 2b with the closer shaft 3b. The housing 21 of the door closer has a main part 21a, the structure of which corresponds to conventional door closers with a hydraulic piston-cylinder system and in whose hydraulic circuit a valve or a blocking device is arranged to fix the sliding arm 4b. Such a device is described for example in DE-OS 33 29 543. At its end facing the hinge side, the housing 21 is extended by an add-on part 21b which receives the control device 6 with the control lever 61.

The housing 21, including the attachment 21b, has a cuboid shape with a convex front 22. Between main part 21a and Attachment 21b remains a gap 23 open toward the front 22, with a Depth of approximately two thirds of the housing diameter. In the gap 23 is the Control lever 61 about a parallel to the longitudinal axis of the leaf door closer 2b Axis rotatably mounted. He is not represented by a spring, for example a spiral spring, held in the starting position shown, in which it projects vertically or almost vertically above the top of the housing. The control lever 61 is used to actuate the locking device for the determination the active leaf 1b.

The blocking device is in the illustrated starting position of the control lever 61 released in the active leaf closer 2b, i.e. that the active leaf 1b continues can move in the closing direction. When the inactive leaf 1a is closed the cover profile 5 in the release position in which the control lever 61 with the Gap 55 is aligned. During the closing process, the control lever 61 engages in the gap 55 in the cover profile 5, but without being deflected. Accordingly, it can the active leaf 1b reach its closed position without being detected. at opened passive leaf 1a is the cover profile 5 by the force of the spring 54 in moved horizontally to its locked position, in which the control lever 61 and the gap 55 are no longer in alignment. When closing the Active leaf 1b hits control lever 61 before it reaches the closed position front vertical leg 5b of the cover profile 5, whereby it from his vertical starting position is deflected. By deflecting the control lever 61 the blocking device in the active leaf door closer 2b is actuated and the Active leaf 1b determined in its current position and in another Closing movement prevented. However, the active leaf 1b can be used again at any time be opened. The temporary determination of the active leaf 1b is necessary so that the passive leaf 1a pass the active leaf 1b and before this the Can reach the closed position. When it reaches the closed position, it is operated with the Slider 41a of the passive leaf 1a connected bolt 43, the actuator 52, whereby the cover profile 5 is moved back to its original release position, in the gap 55 is aligned with the control lever 61. The previously deflected control lever 61 snaps back into the starting position and releases the blocking device free, whereupon also the active leaf 1b closes completely and the rebate 14 of the active leaf 1b in the correct manner on the stop web of the passive leaf 1a comes to rest.

There is an adjusting screw 62 on the side surface 21c of the add-on part 21b, with the help of which the starting position of the control lever 61 varies by up to 180 ° can be. This is necessary, for example, if the one shown Active leaf door closer 2b is not as shown in Figure 1 on one on the left Aisle 1b arranged on the door side, but on a right-hand side Active leaf 1b is mounted. The housing 21 of the leaf door closer 2b is mounted tilted by 180 ° and the control lever 61 would move vertically point below and could no longer come into contact with the cover profile 5. By loosening the set screw 62, the control lever 61 is released from the blocking device decoupled. Then he can pivot freely into his new starting position become. As soon as the control lever 61 is optimally aligned, it becomes locked again by means of the set screw 62 and connected to the blocking device. This method advantageously allows adaptation of the Door closer 2b to local conditions.

By changing the starting position of the control lever 61 by means of the adjusting screw 62 the door angle can also be set up to which the Active leaf 1b can maximally close with the passive leaf 1a still open. This Door angle must be large enough to make the passive leaf 1a problem-free To allow passage through the active leaf 1b. This door angle can be enlarged be by the starting position of the control lever 61 a bit in the direction of Door 1 is inclined and the control lever 6 thus earlier when closing on the Cover profile 5 meets. Conversely, the door angle can be reduced by using the Starting position of the control lever 6 is tilted a bit away from the door 1.

An adaptation of the starting position of the control lever 61 is also possible for that in FIG. 6 shown assembly of a leaf door closer 2b on a door 1 with a rollover Door leaf 1c required. In this version it is on the wing 1b arranged door closers 2b opposite the slide rail 4b and the cover profile 5 moved forward. Accordingly, it is necessary to start of the control lever 61 to incline clearly to the by the overlapping door leaf 1c to compensate for the path difference.

Figure 3 shows a section along line III in Figure 1, but in the closed state of the passive leaf 1a. The passive leaf closer 2a with the piston-cylinder system 24 is fastened to the upper horizontal edge of the passive leaf 1a via two screw connections 25. The slide rail 4a of the fixed-leaf door closer 2a is fastened to the door frame 11 via screw connections 42. The closer arm 31a connected to the closer shaft 3a is articulated via a bolt 43 to the slider 41a guided in the rail 4a.

The slide rail 4a is, as already described in FIG. 1, with a continuous one L-shaped cover profile 5 dimmed, which is shown in Figure 1 side cover caps 51 is placed. The cover caps 51 arranged stationary on the frame 11 and the cover profile 5 is on the cover caps 51 slidably mounted. As best seen in Figure 3, the horizontal leg 5a of the cover profile 5 to form a continuous Surface directly on the horizontal upper edge of the slide rail 41a. The lower end of the vertical leg 5b of the cover profile 5 is approximately at the level of horizontal lower edge of the slide rail 4a, but is offset a little to the front. The arrangement of the cover profile 5 is chosen so that it is in one plane the front surface 22 of the door closer housing 2a. For further improvement of the overall visual impression, the vertical leg 5b of the cover profile 5 one of the front side 22 of the door closer housing 21 comparable convex Curvature on.

The actuator 52 is arranged in the area between the two rails 4a and 4b. The actuator 52 has a short vertical leg 52a, which connected to the vertical leg 5b of the cover profile 5 via clamping screws 53 and a horizontal leg 52b, which is immediately below the plane of the slide rails 4a, 4b extends to the door frame 11. there The actuator 52 also covers part of the passive leaf side from below Rail 4a. In addition, the horizontal leg 52 serves as a screen to that remaining between the two slide rails 4a, 4b and the cover profile 5 Cover opening.

When the inactive leaf 1a closes, the slider 41a moves to the left end of the slide rail 4a and the bolt 43 comes into abutment with the right end of the actuator 52. The closing force of the inactive leaf 1a makes the actuator 52 and the cover profile 5 connected to the actuator 52 moved against the force of the return spring 54 in the release position shifted towards the active leaf side. In this position, that is to say when the passive leaf 1a is closed, the gap 55 in the cover profile 5 is aligned with the control lever 61 arranged on the door closer 2b. When the active leaf 1b is closed, the control lever 61 can enter the gap 55 and the active leaf 1b can reach its closed position without that the control lever 61 is actuated. This position of the control lever 61 when the active leaf 1b is closed is shown in FIG .

FIG. 5 shows a representation corresponding to FIG. 4 for an open and locked active leaf 1b. The inactive leaf 1a not shown in the figure is also in the open position, which is expressed in that the cover profile 5 is moved under the action of the return spring 54 to the inactive leaf side in its locked position, in which the gap 55 is not aligned with the control lever 61 , In this case, the control lever 61 strikes the vertical leg 5b of the cover profile 5 when the active leaf 1b closes. While the leaf 1b is still moving a little further, the lever 61 is pivoted out of its initial position and thereby actuates the blocking device arranged in the active leaf closer 2b. By releasing the blocking, the active leaf 1b is locked in its current position and prevented from moving further in the closing direction, but can be opened again at any time. In the meantime, the passive leaf 1a passes the fixed active leaf 1b and actuates the actuator 52 when the closed position is reached, as a result of which the cover profile 5 is shifted into its release position, in which the gap 55 is aligned with the control lever 61. The control lever 61 now snaps back into its starting position under the action of a spring arranged in the control device 6 and thereby releases the blockage. Thus, the active leaf 1b can then close completely.

A safety valve in the hydraulic circuit of the leaf door closer 2b allows the active leaf 1b manually when applying greater forces despite detection to spend the closed position. The control lever 61 can easily over the position shown are deflected around, closing the active leaf 1b without damaging or bending the control lever 61 or the To enable blocking device.

FIG. 6 shows a representation corresponding to FIG. 4 for a door 1 with a door leaf 1c overturning. In such a case, the door closer 2b is offset to the front relative to the slide rail 4b and the cover profile 5, since the door leaf 1c rests on the frame 11 and does not end flatly with it as shown in FIGS. 4 and 5. This would mean that the control lever 61 comes into contact with the cover profile 5 too late when the active leaf 1b is closed and the passive leaf 1a is still open. The door angle, at which the active leaf 1b would be determined, would under certain circumstances no longer be sufficient to allow the passive leaf 1a to pass. In order to nevertheless achieve timely actuation, the starting position of the control lever 61 is clearly inclined towards the door, as already described under FIG. 2.

However, the invention is not limited to the transmission mechanism shown. In alternative designs, it is also possible to cover profile 5 to be arranged stationary with the gap 55 and instead a separately arranged one To use transmission member, which is actuated by the actuator 52 and covers or releases the gap 55 when actuated.

Furthermore, instead of a hinge-side assembly, the door closer 2a, 2b is also mounting on the opposite hinge side possible. There are no restrictions from this in the function of the invention. A necessary adjustment of the Length of the control lever 61 is simple by screwing on a Adapter piece possible.
