An overload protection is provided to guard against faulty sequence.

Description

The invention relates to a closing sequence controller for a self-closing, a door comprising a passive leaf and an active leaf, in particular a fire door, wherein the active leaf by means of a releasable from the passive leaf Locking mechanism can be determined.

Double-leaf doors of the type mentioned overlap each other in the Middle area, so that the one, forming a passive leaf one Has stop for the other door leaf forming the active leaf, a certain closing sequence is required to close them tightly is when the door panels should be closed properly. To For this purpose, closing sequence controllers are used, which are always the ones for the aforementioned proper closing required sequence ensure the transitions of the two wings into the closed position. A certain order of closing movement of both door leaves is also therefore necessary to get the usually with a lock Only let the active leaf reach the closed position when the the door stop, usually the striking plate or the like having standing leaf is closed.

DE 33 36 739 C2 discloses a closing sequence controller for a self-closing, a door comprising a passive and a moving wing, in particular Fire protection door, known, the door wing each with a swivel arm are connected to the door frame, the swivel arm of the active leaf can be ascertained by means of a locking member which can be released from the passive leaf. The end of the swivel arm of the active leaf is on the door frame side with a sliding guide attached to the door frame guided slider provided, which is lockable by the locking member. The Inactive leaf interacts with an axially adjustable thrust member that acts to release the locking of the slider on the locking member.

Although this construction ensures a safe and reliable Closing sequence control, but it consists of a large number of individual parts, that not only require a lot of space, but also that they are expensive to manufacture are. In particular, due to the relatively elongated training of the thrust member requires the well-known closing sequence controller for both Attachment to the door as well as a lot of space during storage. The many Individual parts also make up the entire closing sequence controller relatively heavy and complicated to set up, so that maintenance or repair work are laborious and time consuming to perform. Because of the large number of parts can also store and stock spare parts be a problem.

The object of the present invention is therefore the above eliminate the disadvantages mentioned and a mechanical Closing sequence controller to create a secured closing sequence double-leaf door guaranteed, but with as few and as possible simply constructed components.

This object is achieved by the features of claim 1.

• der Sperrmechanismus weist mindestens eine axial bewegbare erste Schubstange und ein Sperrelement auf,
• zwischen der ersten Schubstange und dem Sperrelement ist ein bewegbares Sperrglied angeordnet, welches entweder nur eine Bewegung der ersten Schubstange oder nur eine Bewegung des weiteren Sperrelementes zulässt.

According to the invention, the closing sequence controller for a self-closing door comprising a fixed leaf and a moving leaf, in particular a fire door, in which the moving leaf can be locked by means of a locking mechanism that can be released by the fixed leaf, has the following features:

• the locking mechanism has at least one axially movable first push rod and a locking element,
• A movable locking member is arranged between the first push rod and the locking element, which allows either only a movement of the first push rod or only a movement of the further locking element.

Such a closing sequence controller can, for. B. be constructed so that within a basic body is used for the sliding guide at every necessary point which is then fixed at the required point. Consequently is an individual adjustment to the door sizes or to the locking behavior of the doors adjustable. Inside the body are in the longitudinal direction two parallel holes in which Push rods are introduced, each through the sliders of the Standing or moving leaf can be controlled. These are push rods formed so that they are spring-loaded and stops at their ends exhibit. Together with the push rods, the locking member works that z. B. is inserted within a recess in the base body. The Locking element is movably arranged within the recess. The Locking element is removed from its respective position by the push rods then pushed out when evasion of the locking member is possible. To allow the locking member to evade, are located in the push rods indentations preferably in the form of a circumferential groove.

As a result of this configuration, the structure is simple and simple Components a closing sequence controller provided that a secured Guaranteed closing sequence. The construction also has the advantage that the entire closing sequence controller is very compact and can therefore be easily and conveniently installed and removed, e.g. B. at a repair or for maintenance purposes. Since it is made up of only a few and relatively small individual parts, is not just the storage of the whole Closing sequence controller, but also the provision of individual or Spare parts simple and uncomplicated and require little space. at The closing sequence controller can perform maintenance and repair work after the present invention because of its light weight also easily be installed or removed. Later retrofitting is also possible possible within the slide rail.

Figure 11:

a second embodiment of the invention Closing sequence controller.

1 to 10 is the structure and operation of a closing sequence controller according to a first embodiment of the present invention shown. This closing sequence controller is particularly suitable for one Door with a moving leaf and a passive leaf (not in the figures shown) each connected to the door frame via a swivel arm are. The door frame side end of the swivel arm Inactive leaf with one in or on the door frame Slide guide 1 slidably guided leaf slide 2 provided. Furthermore, the end of the swivel arm of the active leaf is on the door frame side with one also slidably guided in the sliding guide 1 Provide active leaf slide 3.

The active leaf, the passive leaf, the door frame and the two swivel arms are general state of the art and are therefore not described in detail here shown or explained.

The closing sequence controller according to a first embodiment of the present The invention comprises a base body 4, which in the sliding guide 1 between the passive leaf slide 2 and the active leaf slide 3 is provided fixed. In the base body 4, two are parallel and in Holes 5a, 6a for receiving which run in the longitudinal direction of the sliding guide 1 a passive leaf push rod 5 and a moving leaf push rod 6 introduced. Here are the passive leaf push rod 5 and Active leaf push rod 6 displaceable in the longitudinal direction of the bores 5a, 6a, if they from the passive leaf slide 2 or from the Active leaf slider 3 are applied. The passive leaf push rod 5 and the active leaf push rod 6 each have at their ends Attacks 7 on. In addition, each of the two push rods 5, 6 each provided with a circumferential groove 5b, 6b. Both push rods 5, 6 are preferably each by a coil spring 5c, 6c in opposite Directions biased so that the passive leaf push rod 5 in the direction of the fixed leaf slide 2 and the active leaf push rod 6 are preloaded in the direction of the active leaf slide 3.

In the base body 4 there is a between the two bores 5a, 6a Recess 8 provided in which a locking member 9 in the form of a rolling element, preferably a cylinder is arranged. The recess 8 is designed so that the locking member 9 in one direction can move transversely to the direction of movement of the push rods 5, 6. Moreover is the locking member 9 dimensioned and arranged so that it either on one side or on the other side over the recess 8 protrudes and with the protruding part either in the hole 5a for the passive leaf push rod 5 or in the hole 6a for the Active leaf push rod 6 protrudes with the protruding part either in the circumferential groove 5b of the leaf push rod 5 or in the Circumferential groove 6b of the active leaf push rod 6 engages. The locking member is thus floating and embedded within the base body 4 controlled via the push rods 5, 6 by the sliders 2 and 3.

The following is the function of the closing sequence controller according to the invention explained.

In Fig. 1 the position of the closing sequence controller is at the zero position of a door shown, in which both door leaves are closed. In this position are the fixed leaf slide 2 on the fixed leaf push rod 5 and the active leaf slide 3 on the active leaf push rod 6 and tension the coil springs 5c, 6c so that the two push rods 5, 6 are in the position shown in Fig. 1. Is located the circumferential groove 5b of the passive leaf push rod 5 in the area of Recess 8, while the center of the circumferential groove 6b of the active leaf push rod 6 by a distance x from the center of the recess 8 or the middle of the locking member 9 is removed. As a result of this arrangement stands the locking member 9 in the bore 5a for the passive leaf push rod 5 and engages in the circumferential groove 5b (see also FIG. 3). So that is Inactive leaf push rod 5 latches while the active leaf push rod 6 can move freely, i.e. is not in the rest position.

The distance x between the center of the circumferential groove 6b and the center of the Recess 8 or the locking member 9 ensures that the Active leaf slide 3 at the minimum open bracket and thus corresponds the path that the active leaf slide 3 to reach the Minimum open angle covered.

If the active leaf is now opened, the active leaf slide moves 3 to the left in Fig. 2. Due to the preload of the coil spring 6c, the active leaf push rod 6 follows the active leaf slide 3 long until it abuts the base body 4 with its stop 7. This state where the active leaf is opened and the passive leaf is closed is shown in Fig. 2.

When the active leaf is closed again, the active leaf slide presses 3 the active leaf push rod 6 again in their shown in Fig. 1 Nullage back. The active leaf can therefore be opened and opened as required be closed as long as the passive leaf is closed.

If the passive leaf is now opened in addition to the active leaf (cf. Fig. 4), remove both sliders 2, 3 from the base body 4. Here the active leaf push rod 5 follows the active leaf slide 3 until it abuts with its stop 7 on the base body 4. In this position the Circumferential groove 6b of the active leaf push rod 6 directly above the recess 8, so that the locking member 9 due to the spring tension standing leaf push rod 5 now in the circumferential groove 6b of the active leaf push rod 6 is pressed. This is the passive leaf push rod 5 released and moves in Fig. 4 to the right until it with their stop 7 abuts the base body 4. This state is in FIG. 5 shown. The active leaf push rod 6 is now blocked during the Inactive leaf push rod 5 is freely movable.

The sequence of movements described above also takes place, of course Active leaf and passive leaf can be opened at the same time.

When the active leaf and the passive leaf close, the active leaf slide moves 3 against the active leaf push rod 6 and is in this Position held because the locking member 9 has no way in the circumferential groove 5b of the passive leaf push rod 5 and thus the Active leaf push rod 6 locked in the locked position. The passive leaf slide 2 is in turn able to push the passive leaf push rod 5 in to press their starting position since it is not in the resting position, is not prevented from moving by the locking member 9. Only when the passive leaf push rod 5 is in the starting position can the active leaf slider 3 or the spring force the locking member 9th press into the circumferential groove 5b of the standing flight push rod 5 and thus move the active leaf push rod 6 to its zero position and the passive leaf push rod 5 lock. This ensures a correct closing sequence.

The sequence of movements in the closing sequence controller during the closing process is shown in Figs. 6 to 8.

FIGS. 9 and 10 show a closing sequence controller, as already described above shown with an overload protection. Therefor is located within the base body 4 in the area of the passive leaf push rod 5 preferably in the area of the locking member 9 an additional Recess 10. The recess 10 is in its longitudinal extent limited laterally by the bores 5a, which merge into the recess 10. The width of the recess preferably extends in Direction towards the wall of the sliding guide 1.

Now the active leaf slider 3 continues in the direction of the base body 4 pressed, so the active leaf push rod 6 with its outer circumference the locking member 9 against the outer circumference of the passive leaf push rod Press 5. Despite the open inactive leaf, this gives way the existing recess 10 from the side (see Figures 9 and 10). It is therefore a deliberate overpressure and therefore a closure of the active leaf in front of the passive leaf. By overload protection it is avoided that the closing sequence controller is damaged if z. B. willfully pressed the active leaf in front of the passive leaf. It it is understood that the base body 4 is designed so that everyone required position within the sliding guide 1 inserted and fixed can be. This is an individual adaptation to the building situation given the door.

The above description of the exemplary embodiments according to the present Invention serves only for illustrative purposes and not for Purposes of limiting the invention. Are within the scope of the invention various changes and modifications possible without the scope to leave the invention and its equivalents.
