EP2208846B1 - Device for controlling the closing sequence of double-leafed revolving doors - Google Patents

Description

The invention relates to a device for controlling the closing sequence of two-leaf swing doors by means of a slide rail closer, wherein the one door is a unterschlagender, so-called passive leaf and the second wing is a sweeping, so-called scroll.

The device according to the invention is particularly advantageous for such doors, which have to meet a security claim, in particular for fire doors with so-called panic and escape function, advantageously applicable.

Fire doors must prevent the spread of fire from the room on one side to the room on the other side of the door for a certain amount of time specified by the relevant standard. Of course they can only do that if they are properly closed. Due to folds which represent a projection of one door leaf in front of another door leaf, it is necessary for the proper closing of a double-leafed fire door to close the wings in the correct order. This is the case when, from the open state, the passive leaf is first brought into the closed position and only then is the active leaf. To ensure that this takes place safely even in case of fire, the wings are not only provided with a drive which automatically moves the door in the closed position, but also with a device for controlling the closing sequence. This device is intended to cause the two door leaves to be closed automatically in the correct order.

If, when the inactive leaf is open, the active leaf also open, for example driven by a spring, executes a closing movement leading the inactive leaf, then this closing movement is stopped by the action of the device for controlling the closing sequence at a certain opening angle until the inactive leaf is in its closing movement the active leaf sufficiently far ahead, so that the correct closing sequence is guaranteed.

In sliding rail door closers a pivoting arm protrudes from a door leaf to a sliding block, which is mounted longitudinally movably in a sliding rail arranged on the upper frame part of the door frame. With the door closed, that end of the swivel arm, which is fastened to the door leaf, lies closer to the pivot axis of the door leaf than that end of the swivel arm which is connected to the sliding block. During the majority of the closing pivoting movement of the door leaf, the sliding block slides in the slide rail away from the axis of rotation of the door leaf.

The DE 33 36 739 C2 shows a device of the generic type. The sliding block for the inactive leaf and the sliding block for the active leaf are guided in a common slide rail. For the above-described controlling the closing sequence of the two door wings, the movement of the sliding blocks associated with the two door leaves is mutually forcibly associated with their movement. When the inactive leaf is opened beyond a certain minimum opening angle, any closing movement of the active leaf is stopped at a certain opening angle by blocking the sliding block connected to the inactive leaf via a pivoting arm against movement in the sliding rail away from the rotary axis of the inactive leaf by a holding mechanism. The blocking action of the holding mechanism is canceled only by closing the passive leaf by a protruding from the sliding block of the passive leaf in the direction of the holding mechanism of the active leaf part by the movement of the sliding block of the passive leaf with said holding mechanism comes into contact and thereby releases the blocking effect.

For this closing sequence control to work, it is important that when the passive leaf is opened, the active leaf is above the said waiting position, ie over a certain minimum opening angle out, open. Furthermore, it is important that when closing the passive leaf and already released from the blockade active leaf, the closing movement of the active leaf that of the passive leaf can not catch up prematurely.

All this is easily adjustable when the waiting position of the active leaf is at a very large opening angle and if it can be ensured that the active leaf is forcibly opened during an opening movement of the passive leaf at least up to this position. This co-opening is done by drivers such as in the AT 403 400 B and in the DE 10 200 403 1937 A1 described. It has proved to be disadvantageous that the minimum opening angle of the active leaf required for the proper functioning of the closing sequence control is so great that visually very troublesome large drivers are necessarily required for this purpose. Thus, a major advantage of Gleitschienentürschließern, namely their visual unobtrusiveness, counteracted.

The cause of the disturbingly large minimum opening angle is that, for geometrical reasons, the ends of the pivot arms connected to the sliding blocks in the last part of the closing movement of the door leaves are hardly moved away from the pivot axis of the relevant door leaf, and often even toward it. For holding the active leaf in the waiting position and for the defined release of the active leaf from this position, it is necessary that the Gleitsteinpositionen necessarily connected to the respective door positions lie in such a range of movement of the sliding blocks, in which these during a closing movement of their door leaves a clear Movement component from the axis of rotation of their door wing have away.

The EP 1 333 142 A2 describes a closing sequence control for double-winged swing gates with slide rail door closer, wherein the passive leaf attributable to the sliding block during the last part of the closing movement of the passive leaf on the axis of rotation of the inactive leaf. This movement is translated into an oppositely directed movement of a transmission part in the slide rail, ie away from the axis of rotation of the passive leaf, by which the barrier of the active leaf against closure is canceled. The construction requires the attachment of a Übersatzungsteils on the slide and it is only applicable if then the lock of the active leaf is to be solved at such an opening angle of the inactive leaf, in which the sliding block of the inactive leaf during the closing movement of the inactive leaf clearly on the axis of Steady to move.

The object underlying the invention is to improve the known, based on slide rail closers devices for controlling the closing sequence of two-leaf swing doors to the effect that when opening the inactive leaf with a smaller minimum opening angle of the active leaf, the Auslangen can be found. The limitations of the construction methods according to EP 1 333 142 A2 brings with it, should be overcome.

The invention is illustrated by means of sketchy drawings to different execution principles. The drawings are not meant to be limiting. Fig. 1 : shows on the basis of a diagram and a geometry sketch, the movement of a slide rail end of a swing arm in dependence on the opening angle of a door leaf. This illustration is valid both for designs according to the prior art, as well as for construction according to the invention. Fig. 2 : shows with view from below a first, not inventive variant of an arrangement of a sliding block and a relative to the sliding block by movement of the sliding arm connected to the pivot arm forcibly moving part. Fig. 3 : shows a perspective view of a second, non-inventive embodiment of an arrangement of a sliding block and a relative to the sliding block by movement of the sliding arm connected to the pivot arm forcibly moving part. Fig. 4 : shows in perspective view the parts of Fig. 3 in a changed relative position to each other and from a slightly different line of sight Fig. 5 shows a view from below in a partial sectional view of a third embodiment of an inventive arrangement of a sliding block and a relative to the sliding block by movement of the sliding arm connected to the pivot arm forcibly moving part.

Fig. 6 : shows with view from below a fourth, non-inventive embodiment of an arrangement of a sliding block and a relative to the sliding block by movement of the sliding arm connected to the pivot arm forcibly moving part.

The upper part of Fig. 1 is a partial sectional view from above of a pivotable about an axis 11 door 1, from the upper end face of a pivot arm 2 to a sliding block 3 in a slide rail 4 projects, which is aligned horizontally, parallel to the closed door plane. For reasons of visibility of the slide 4 in Fig. 1 only their situation indicated by dashed lines.

The lower part of Fig. 1 is a diagram showing the displacement s of Gleitsteines 3 relative to its position with the door closed 1, depending on the opening angle of a door leaf 1. Positive displacement means increased distance of the sliding block to the axis of rotation 11 of the door leaf.

It can be seen that, in the illustrated geometric relationships, the sliding block 3 is only displaced in the direction of the rotation axis 11 during the closing movement of the door leaf as long as the opening angle of the door leaf is more than approximately 15 °. At a smaller opening angle of the sliding block 3 is moved away from the axis of rotation 11.

Regardless of whether the wing 1 is a leaf or a passive leaf, according to the prior art, only that pivoting range of the door leaf 1 for the Controlling the closing sequence to be used, which exceeds that dead - point angle is at which the linear direction of movement of the associated sliding block reverses with uniform angular movement of the door leaf. According to the invention, however, the permissible swivel angle range is extended downwards, since not the immediate movement of the sliding block is used for the control of the closing sequence, but the movement of a relatively moved to separate part, which in the relevant part of the closing movement of the door leaf, which he is assigned by a transmission mechanism forcibly more than the sliding block is moved parallel to the orientation of the slide away from the axis of rotation of the door leaf.

The interaction of this separate, belonging to a door part with a part of the other door to control the closing sequence by blocking or allowing a movement, for example, according to the known from the prior art means for the interaction of the two each other door associated sliding blocks and therefore is not part of deeper discussions here. In the most common mode of operation for a locking part is used stationary in the slide, on which the movement of the active leaf associated part (sliding block) at clearly open wing away from the axis of rotation of the active leaf away, as long as blocked by a from the inactive wing at its Closing movement of the axis of rotation away moving part (sliding block), which usually comes in its movement via a connecting rod with the locking part and / or held on the locking part, the passive leaf associated part in contact, the blockage is canceled.

In the non-inventive embodiment of Fig. 2 is a sliding block 23.1 guided linearly movable in the slide 4 and pivotally connected to the axis indicated by dash-dotted lines with the pivot arm 22. A second part 23.3, which either holding part (a Passive leaf) or release part (of a moving leaf), is also linear at the, the pivot axis of the door remote side of the sliding block slidably disposed in the slide rail 4. The pivot arm 22 protrudes with an end beyond the fulcrum on the sliding block 23.1 and comes towards the end of his taking place when closing the associated door leaf rotation with this end on a surface of a portion 23.2 of the holding or release member 23.3 in contact and slides along this surface , Since the radial distance of said surface on the part 23.2 to the axis of rotation of the swivel arm on the sliding block 23.1 decreases with the direction of rotation of the said end portion of the swivel arm 22, the holding or releasing part 23.3 is pushed away from the sliding block 23.1 by the end region of the swivel arm 22. It is advantageous to form the surface on the part 23.2 with respect to the axis of rotation of the swivel arm on the sliding block 23.1 as a logarithmic (equiangular) spiral, since then takes a uniform translation of the angular rotation of the pivot arm in a relative linear movement between the sliding block 23.1 and holding or releasing part 23.3 ,

Via a rod 5, the holding or releasing part 23.3 can cooperate with other parts in the same way as a sliding block according to the prior art for the purpose of regulating the closing sequence.

In the non-inventive embodiment of Fig. 3 and Fig. 4 For example, the slider 33.1 is pivotally connected to the pivot arm 32 at the axis indicated by a dot-dash line. A holding or releasing part 33.3 is likewise arranged so as to be linearly displaceable in the slide rail 4 at the side of the sliding block 33.1 remote from the pivot axis of the door leaf. The pivot arm 32 protrudes with an end portion 32.1 beyond the pivot point on the sliding block 33.1 out and comes towards the end of his taking place when closing the associated door leaf rotation with an inclined plane 33.4 of a translation part 33.2 into engagement. The translation part 33.2 lies between the sliding block 33.1 and the holding or releasing part 33.3 and abuts on a second translation part 33.11 also via an inclined plane 33.5. The second translation part 33.11 could also be formed integrally with the sliding block 33.1. By pressure of the end area 32.1 of the pivot arm 32 during the last part of the closing movement of the associated door leaf, the translation part 33.2 is displaced normal to the pivot plane of the pivot arm 32 against the second inclined plane 33.5. At this he slides off, whereby he receives a parallel to the slide rail 4 movement component, by which he moves the holding or releasing part 33.3 away from the sliding block 33.1. The holding or releasing part 33.3 in turn acts like the holding or releasing part 23.3 described for the previous example for the purpose of controlling the closing sequence with the sliding block or holding or releasing part of the second door leaf.

By applying two oblique planes acting in different directions Fig. 3 and Fig. 4 instead of only one inclined plane according to Fig. 2 , a larger gear ratio of the way can be achieved without it comes through friction to a self-locking and you can achieve more favorable balance of power in the parts involved in the translation.

The embodiments according to Fig. 2 to Fig. 4 are advantageous especially for passer-side application, so suitable for moving a holding part, since it does not have to work on the parts involved in the translation taking place on an inclined plane relative displacement to the outside and thus (theoretically) no external force to be overcome must, but only with stopped relative movement between the individual parts a force needs to be transmitted.

In the inventive arrangement of Fig. 5 is a translation part 43.2 with the pivot arm 42 into engagement and even on the sliding block Gleitsteinteil 43.1 rotatably mounted. A holding or releasing part 43.3 is movably guided on the sliding block 43.1 parallel to the longitudinal direction of the slide rail 4. via a radially far outwardly projecting extension 43.4 is the translation part 43.2 via flanks of a recess on the holding or Release part 43.3 with this on the principle of interaction of gear and rack engaged. Upon rotation of the translation part about its axis on the sliding block, the holding or releasing part is thereby displaced linearly relative to the sliding block. The holding or releasing part 43.3 is that which cooperates with other - not shown here - parts, which are attributable to the second door, for the purpose of controlling the closing sequence.

The construction according to Fig. 5 is also good for a stand-side application, so suitable for moving a release part.

In the non-inventive embodiment of Fig. 6 a sliding block 63.1 is linearly guided in the slide rail and pivotally connected to the pivot arm 62. A second part 63.3, which is either holding part (of a passive leaf) or release part (of a moving leaf), is also arranged to be linearly displaceable in the slide rail on the side of the sliding block remote from the pivot axis of the door leaf.

The pivot arm 62 protrudes with an end portion on the fulcrum on the sliding block 63.1 and comes towards the end of his taking place when closing the associated door leaf rotation with this end on a surface of an attachment part 63.2, on the holding or. Release part 63.3 is rigidly fixed, in contact and slides along this surface. Since the radial distance of said surface of the attachment 63.2 to the axis of rotation of the pivot arm on the sliding block 63.1 with the rotation of said end portion of the pivot arm 62 in the parallel to the slide rail (whose direction in, Fig. 6 is indicated by the longer dot-dashed line) decreases, the holding or releasing part 63.3 is pushed away by the end portion of the pivot arm 62 of the sliding block 63.1 away.

To this, in itself Fig. 2 to Fig. 4 shown principle is in Fig. 6 additionally illustrates that the attachment part 63.2 is adjustably mounted on the holding or releasing part 63.3 - by a screw-slot arrangement 63,4 -, so that thus a move the range of movement of the holding or release part 63.3 opposite the sliding block 63.1 and thus an accurate Einjustieren the tripping behavior is enabled.

Additionally is in Fig. 6 shown how the sliding block 63.1 and the holding or release part 63.3 by the arrangement of a spring 63.5 - in the example shown, a compression spring - can be moved together so that the end portion of the pivot arm 62 on the aforementioned surface of the attachment part 63.2 always applied to pressure.

In all embodiments, the pivoting movement of a pivoting arm is translated into a linear movement of a holding or releasing part relative to the sliding arm connected to the sliding block.

When dealing with the individual embodiments, it quickly becomes clear that, due to the great variety of useful embodiments of mechanical translations, adjustable fastenings and arrangements of springs, beyond the examples shown, there is a largely incomprehensible variety of useful variants for a device of the type mentioned , A significant advantageous difference from the prior art is that at least for one of the two parts, holding part or release part not just a sliding block is used, but a relatively movable, driven by the closing movement of a door part, which during the relevant angular range of the closing movement of the Door leaf relative to the sliding block performs a significant movement in the direction away from the axis of rotation of the relevant door leaf.

For reasons of reliability in case of power failure and fire, it makes sense at least to apply only mechanical transmission elements for driving the required relative movement between the individual parts involved in the control of the closing sequence.

Due to the construction methods according to the invention, it is easily possible to give the release of the closing movement of the active leaf until almost completely closed passive leaf. It also makes it possible to set the waiting position of the active leaf at a very small opening angle. Through these possibilities safety and comfort are gained and it can be costly and unsightly Mitnehinerklappen eliminated.

The following claims relate exclusively to the construction according to Fig. 5 , The construction according to the Figures 2 . 3 . 4 and 6 are not affected by the claims.
