Abstract

The through-way door leaf is fixed by a locking mechanism which is released by the fixed leaf. The locking mechanism has a clamping body (100) which jams the clamping-bar (6) cooperating with the through-way leaf. The fixed leaf cooperates with a release bar (7) which releases the clamped position between the clamping body and the clamping bar. An overload protector (13,14) wholly or partly releases the locking mechanism when great force is exerted on the through-way leaf.

Description

The invention relates to a closing sequence controller for a self-closing, a standing and a wings comprehensive door, especially fire door, wherein the active leaf by means of a releasable from the passive leaf Locking mechanism can be detected and optionally an overload protection having.

Two-leaf doors of the type mentioned overlap each other in the Middle area, so that the one, forming a solid leaf door a Having a stop for the other door wing forming the moving leaf, whereby a certain closing sequence is required for their tight closure is, if the door wings are to be closed properly. To For this purpose closing sequence controllers are used, which always the for the aforementioned orderly closing required order ensure the transitions of the two wings in the closed position. A certain order of closing movement of both leaves is also therefore necessary to the usually provided with a lock Only then let the active leaf reach the closed position, if the the door stop forming, usually the strike plate or the like having passive leaf is closed.

From DE 33 36 739 C2 is a closing sequence controller for a self-closing, a standing and a wings comprehensive door, in particular Fire door, known, whose door wings each with a swivel arm the door frame are connected, wherein the pivot arm of the active leaf can be detected by means of a releasable from the inactive leaf locking member. Here is the door frame end of the swing arm of the active leaf slidable with a mounted in a door frame slide guided slider provided, which is detectable by the locking member. Of the Inactive leaf interacts with an axially adjustable pusher member, the acts to release the determination of the slider on the locking member.

DE-A-3 604 091 discloses all features of the preamble of claim 1.

Although this construction ensures a safe and reliable Closing order, but it consists of a large number of individual parts, not only need a lot of space, but also to produce consuming are. Due to the relatively elongated training in particular the thrust member, requires the known closing sequence control both at the attachment to the door as well as storage a lot of space. The many Items make the entire door lock controller beyond also relatively heavy and complicated in construction, so maintenance or Repairs are laborious and time consuming to carry out. Because of the large number of parts and the storage and provision of Spare parts a problem. Furthermore, there is a risk that at a Closing attempt of the active leaf, if the passive leaf is still open, the locking member is damaged and consequently a subsequent closing attempt of the standing and active leaf in the correct order no longer is possible. Such closing attempts of the active leaf in still open Position of the passive leaf may be due to carelessness respectively.

The object of the present invention is, therefore, the above to eliminate mentioned disadvantages and a mechanical Closing sequence to create a secure closing sequence of a door ensures, but with as few and also simply constructed Achieved components.

The solution of this object is achieved by the features of claim 1.

• Der Sperrmechanismus weist einen Klemmkörper auf, der klemmend auf eine mit dem Gangflügel in Wirkverbindung stehende Klemmstange einwirkt,
• der Standflügel steht mit einer Auslösestange in Wirkverbindung, mit deren Hilfe die Klemmung zwischen dem Klemmkörper und der Klemmstange aufhebbar ist.

According to the invention, the closing sequence controller has the following features for a self-closing door comprising a standing and a moving leaf, in particular a fire-protection door, in which the active leaf can be immobilized by means of a locking mechanism which can be released by the inactive leaf.

• The locking mechanism has a clamping body which acts in a clamping manner on a clamping rod which is operatively connected to the active leaf,
• the inactive leaf is in operative connection with a release rod, by means of which the clamping between the clamping body and the clamping rod can be canceled.

Furthermore, an overload protection is provided, which at high force on the active leaf in its self-locking state release causes the locking mechanism. This is under the term Self-locking on the one hand a violent pushing of the active wing understood with very high forces or the impossibility of squeezing.

As a result of this embodiment of the closing sequence controller according to the invention is achieved that in the case of attacking on the moving wings forces achieved release of the locking mechanism despite open wing is before the locking mechanism due to the attacking forces on Active leaf an impairment or even irreversible damage experiences. In doing so, we only maintain the release of the locking mechanism for so long get how the extra power is effective. After a reduction The power leaves the aisle in its position.

To fix the active leaf with open wing is a in the Sliding guide or slide existing body provided, the includes a clamp body. The clamp body points a sleeve having a tapered interior. In this case, the larger opening of the interior in the opening direction of the moving leaf slider. At the same time is on the active leaf slider a clamping rod firmly attached, resulting in a movement of the Moving leaf slider in the slide with this back and forth. An existing on the passive leaf slider trip bar is also moved with a movement of the passive leaf slider. The Sleeve, which is located in the clamp body, stands under the effect a spring. This is a socket permanently in the direction of the Solid leaf slide loaded. In addition, in the conical tapered Clamping body (interior) a ball race provided to a uniform force transmission from the spring to the ball race and In order to ensure the socket is moreover between the Ball ring and provided in the interior of the sleeve spring a Disc arranged.

As a result of this configuration is made with a few and simple Components provided a closing sequence control, which is a secured Guaranteed closing sequence. The design also has the advantage that the entire closing sequence controller is very compact and therefore easy and convenient to install and remove, z. B. at a repair or maintenance. Since he is only a few and is relatively small items, not only the storage of the entire Closing order, but also the provision of individual or spare parts simple and uncomplicated and requires little space. at Maintenance and repair work, the closing sequence controller after the present invention because of its low weight also problem-free be built or expanded. Also is a later retrofit easily possible.

Furthermore, the necessary force to respond to the overload protection be adjusted continuously. Furthermore, it is possible the overload protection basically switch on or off.

The subclaims have advantageous developments of the invention Go to content.

FIGS. 1 to 6:

The structure and operation of a closing sequence controller according to the invention.

FIGS. 7 to 8b:

The structure and the design of the closing sequence controller according to the invention with an overload protection.

In Figs. 1 to 6, the structure and operation of a closing sequence controller represented according to the present invention. This closing sequence controller is particularly suitable for a door, in which a moving wing and a stationary leaf each via a pivoting arm with the door frame are connected. Here is the door frame end of the swing arm of the inactive leaf with a sliding guide attached to the door frame 1 slidably guided passive leaf slider 2 provided. Farther is the door frame side end of the swing arm of the active leaf with a likewise guided in the sliding guide 1 sliding leaf slider 3 provided.

The active leaf, the fixed leaf, the door frame and the two pivot arms are general state of the art and therefore not closer illustrated or explained ..

The closing sequence controller according to the present invention comprises a Base 4, in the sliding guide 1 between the passive leaf slider 2 and the active leaf slider 3 is provided. By doing Base 4 is a clamping body 100 is arranged. This one has one Sleeve 5 with a tapered interior. The larger opening the interior points in the opening direction of the moving leaf slider 3, d. H. to the right in Fig. 1. On the moving leaf slider. 3 is a clamping rod 6 fixedly attached, which in a movement of the Active leaf slider 3 in the slide 1 with this back and forth emotional. On the passive leaf slider 2, a trip bar 7 is fixed attached, resulting in a movement of the passive leaf slider. 2 also moved. The trip bar 7 is preferably hollow, so that the clamping rod 6 through the main body 4, through the interior the trip bar 7 and preferably also by the passive leaf slider 2 can go through.

In the sleeve 5, a socket 8 is provided, which at least partially under the action of a spring 9 is. In the embodiment, two springs 9 used to achieve a better clamping effect, the one Spring 9a within the tapered interior and the other Spring 9 outside the interior between a stop edge of the Socket 8 and an end face in the region of the smaller opening of the sleeve 5 is provided. By one spring 9, the socket 8 is permanent loaded in the direction of the passive leaf slider 2, d. H. to the left in Fig. 1. The spring 9a presses the ball race in the direction of an inner cone the sleeve 5 (direction locking position) and thus partially the Socket 8 in the direction of the passive leaf slider. 2

In the tapered interior of the sleeve 5 is still a ball race 10 provided. For a uniform power transmission of the spring 9 on the ball race 10 and thus ensured on the socket 8 is is between the ball race 10 and in the interior of the sleeve 5 provided spring 9 a disc 11 is arranged. Furthermore, the Socket 8 via a fuse element 12 in the interior of the sleeve fifth secured so that they do not slip out of the sleeve 5 or fall out can.

In the following, the function of the closing sequence controller according to the invention will now be described explained.

In Fig. 1, the position of the closing sequence controller in the zero position of a door shown, in which both doors are closed. The passive leaf slider 2 and the active leaf slider 3 are in their initial position and arranged on the passive leaf slider 2 trip bar 7 pushes the sleeve 8 of FIG. 1 to the right, so that the ball race 10 can exert no clamping action on the clamping rod 6. Consequently can with the inactive leaf closed the moving leaf slider 3 and so that the active leaf are moved freely, as by the on-wing slider 3 arranged double arrow is indicated in Fig. 2.

As soon as the inactive leaf is opened (see Fig. 3), the passive leaf slider is removed 2 of his shown in FIGS. 1 and 2 zero position and takes the trip bar 7 with it. The socket 8 follows conditionally by the spring (s) 9 of the trip bar 7 until they pass through the fuse element 12 is stopped. Consequently, due to the Spring 9a of the ball ring 10 in Fig. 3 move to the left until, until there is no contact between the bushing 8 and the ball race 10, d. H. until it rests against the inner cone of the sleeve 5. Now is the ball race 10 in its clamping position. Leave in this position the active leaf and thus the active leaf slider 3 only in Move opening direction, d. H. to the right in Fig. 3. A movement in Closing direction is no longer possible, since the ball race 10, the clamping rod 6 clamps and thus prevents their movement in the closing direction (See also Fig. 4).

Now, when the inactive leaf is closed, the trip bar moves 7 together with the passive leaf slider 2 again in the direction to their zero position, d. H. to the right in Fig. 5. This is what happens a contact between the trip bar 7 and the beech 8. At a further movement of the passive leaf slider 2 then pushes the trip bar 7, the sleeve 8 inwardly into the sleeve 5, so that the ball race 10 is released from its clamping position and thereby the clamping bar 6 releases, so that the active leaf in its initial position can move (see Fig. 6). Thus, a correct closing sequence is guaranteed.

After so far the general mode of action of the invention Closing sequence controller has been described below in detail 7 to 8b on the specific embodiment and mode of action the overload protection according to the invention for the closing sequence controller received.

As a comparison of FIGS. 1 and 7 shows, the closing sequence controller according to Fig. 7 additionally an adjusting screw 13 and a lock nut 14 on. The adjusting screw 13 is in this case in the socket 8 by means of a provided in the socket 8 and thread not shown screwed and can be locked by means of the lock nut 14 in position become.

The interaction of the adjusting screw 13 and the lock nut 14th (To lock the adjusting screw) can be in a simple form of the Fig. 7 and 8 and the respective schematic detail enlargements of Fig. 7a and Figs. 8a and 8b.

In Fig. 7 is the closing sequence control according to the invention with overload protection shown in the zero position, d. h., the active leaf slider 3 is freely movable, as long as the passive leaf slider 2 with its trip bar 7 presses the socket 8 to the right. As in particular Fig. 7a is removable, exercises in this state, the ball race 10 no clamping action on the clamping rod 6, since the ball race 10 is not the conical Interior of the sleeve 5 touched.

On the other hand, there is the closing sequence control with overload protection according to FIGS. 8, 8a and 8b in their latching position, d. h., the trip bar 7 of the passive leaf slider 2 is no longer with the socket 8 in touch. In this position, the active leaf slider 3 and thus the active leaf only in the opening direction, d. H. in Fig. 8 in the direction movable to the right.

Now, in the latching position shown in Fig. 8, the adjusting screw 13 used and over the located in the socket 8 thread guided longitudinally movable, can thereby be the clamping force (and thus the Force for forcibly overpressing the active wing) differently set strongly, d. H. when screwing the adjusting screw 13 in the bushing 8 reduces the clamping force and when unscrewing the adjusting screw 13 increases the clamping force. The adjusting screw 13 can be screwed so far into the socket 8 until the contact between ball race 10 and conical interior of the sleeve 5 is solved, even with the inactive leaf. The consequence of this longitudinally movable adjustment of the adjusting screw 13 so conditionally at the same time an adjustment of the clamping force, which by the ball race 10 acts on the clamping rod 6 and leads in the maximum screwed State of the adjusting screw 13 in the socket 8 to turn off the Closing sequence control, as shown in Fig. 8b, if necessary is. The lock nut 14 serves in each case for locking the Adjustment screw 13 in their respective setting position.

In other words, by screwing the adjusting screw 13 in the socket 8 is not only a general overload protection created, but it can also be the degree of overcoming the overload protection required continuous force set become.

Although not shown, the overload protection may also be so be designed that in place of the adjusting screw 13 and the lock nut 14 only the cone angle α shown in Fig. 7a of the conical Interior of the sleeve 5 is designed to be adjustable, to thereby also the strength of the clamping force of the ball race 10 against the clamping bar 6 to be able to adjust.
