Abstract

One of the normally active double doors has an anti-panic lock with catch bolt (1), while the other door is normally inactive and also has a counter-lock (2) with anti-panic lock. The counter-lock has a top and bottom edge bolt (3,4) with drive mechanisms and a striking-plate opening (5) for the catch bolt. The counter-lock has a horizontally movable ejector (6) ejecting the catch bolt out of the striking-plate opening. The connections for the top and bottom edge bolts with their drive mechanisms are formed by threaded points (7) on the ends of the edge bolts facing the counter-lock. The threaded points are screwed into nuts (8) which are fixed into the drive pieces (16,17) of the edge bolts.

Description

The invention relates to a counter lock in the preamble of claim 1 Art.

For emergency doors with double leaves and with an anti-panic opening it is envisaged that one of the door leaves is normally active, while the other is usually inactive. This means, that only the normally active door leaf in normal Terms of use is open (no emergency situation), whereby the entrance or passage through one of the door panels is sufficient. In this case it is normal inactive door leaves permanently locked. Usually active door leaf is with a lock with a latch with a Anti-panic opening by means of a push rod, a door handle or doorknob. The normally inactive door leaf is provided with a counter lock, on which the present Invention relates, this counter lock a striking plate for the latch of the normally active door lock and respective upper and lower square bolts or locking bars having. The counter lock also enables an anti-panic opening (using a push rod, door handle or doorknob), at the at the same time drive devices for the bolt and one Ejection device are actuated, which the trap from the Strikes plate opening, which overall ensures that in an emergency, the normally inactive door leaf can move without Disability opens even if the normally active one Door leaf is not operated.

With such counter locks for anti-panic emergency doors must be sure that both the bolt bolt from their striking plate openings on the upper part of the door frame or pulled out on the floor as well as the latch of the lock in the active door leaf safely from the strike plate of the counter lock is expelled.

To ensure this is a reliable connection each transom with its drive device and the Ejection device required for the trap. The square bars must not shift relative to their drive device, because this changes their effective length with respect to the Lock points would change that in the top and bottom Frame parts of the door are formed. If not reliable Connection exists, gravity and that act through that continuous beating of the normally active door wing Vibrations and the actual actuation of the counter lock together in order to progressively sink the square bolt to work. The relative drop in the top Edge locks can have the consequence that there is no closure on the upper closure point with the frame gives more, in In this case, the normally inactive door leaf can only be its lower square bolt is fixed. On the other hand, it can relative lowering of the lower transom a permanent locking condition cause what in the lower frame part of the door is particularly serious if it is an anti-panic emergency door which, due to its peculiarity, is without any Disability must open at all times, and especially then when an emergency occurs.

Furthermore, it is known in counter locks, the work movements the drive devices for the edge bolts and the Ejecting device via levers that are very easy to effect reach the amplitudes required for these working movements can, even if there is a game in the connection facilities the bolt or its connection to the Drive device occurred. The disadvantage of this known Lever mechanisms are that they are very complicated and are not very compact. On the one hand, these properties make it more difficult the creation of standardized dimensions for the distances between the edge of the counter lock and the axis of the bolt bolt as well the axis of the rotating nut that is actuated to open of the counter lock itself, and on the other hand these properties result in considerable dimensions for the Counter lock housing, which makes this difficult to adapt to the castle in terms of its external design, which is built into the normally active door leaf.

The invention is based, a counter-lock the task to create the type mentioned, with a compact structure safe actuation of the Edge bolt and the ejection device allows.

This object is achieved by the invention defined in claim 1 solved.

Advantageous refinements and developments of the invention result from the subclaims.

The counter lock according to the invention results in a precise and reliable connection of the edge bolts with their drive devices.

The connection devices of the upper and lower edge bolts with their respective drive devices are preferred formed in that this bolt has respective thread tips have, which are screwed into respective nuts, which in the drive devices of these bolt bolts or locking bars are set, preferably a self-locking leaf-shaped Brace is provided which is in the form of a first and second leg formed "U", each against the first and second end faces of the nuts abut these end faces with respect to first and second end faces the forward movement direction of these thread tips at Are screwed into these nuts. The first and second legs have respective first and second openings on in the axial direction with the bore of the nut are aligned, the first or relatively wide opening has a diameter which is suitably somewhat larger than the outside diameter of the thread tips, while the second or relatively narrow opening has a diameter that between the core diameter and the outside diameter of the Thread tips are.

This connection of the edge bolts by means of a self-locking Bracket gives the desired reliability and a large one Simplicity and economy. For coupling the edge bolt the thread tip passes through its drive device of the square bolt the upper opening without difficulty the self-locking bracket and is in the mother of the Drive device screwed in until the thread tip is open protrudes from the other side of the mother. Then the bevel occurs End of this thread tip into the second opening (narrow Opening) and jammed when trying to screw it in again the beginning of the thread due to its larger size Outside diameter in the second opening, then at further screwing causes the axial pressure of the thread tip, that the second leg of the clip is taken, which causes tilting and elastic opening of the Parenthesis results, so that almost only part of the edge the first opening (wide opening) against the edge of the threads strikes and jams, the further screwing is prevented. The more you try to screw in to continue, the more the deadlock increases in the first opening of the bracket. In this way becomes a connection of the edge bolt with its drive device with the desired strength and reliability achieved.

Furthermore, it is preferably provided that the drive movements the bolt and the ejector over one special mechanism are syrichronized, which in the Opening the counter lock simultaneously pulling back of the two drive devices (with the respective bolt bolts) and ejecting the latch of said lock caused by the ejector. For this purpose, the Drive devices of the upper and lower transom through respective upper and lower slides formed in the vertical direction are guided and their vertical displacements to each other and to the one guided in the horizontal direction Movement of the ejection device via a rotating disc are related, the three radial guide slots, namely has first, second and third guide slots, in those in the longitudinal direction of the first, second and third bolts are performed, each with the ejector, with the upper slide or with the lower slide are connected. The ejection device has respective front and rear end faces against the trap or against the End of a radial arm come to rest, which rotates with it a rotatable nut is connected to the opening process of the counter lock is operated. This concept of the mechanism enables much more compact constructions than the known ones Constructions based on power transmissions pivotable lever. On the one hand, this enables creation standardized dimensions for the distances between the edge of the Counter lock and the axis of the bolt and the axis of the rotatable nut, and on the other hand there is a larger Flexibility in terms of the dimensions of the housing Counter lock so that this matches the design of the lock of the normally active door leaf and other elements of the Construction of the door can be customized.

The working movement of the ejection device takes place between respective rear or rest positions and front or ejection positions, with the striking plate opening in the rear position the trap mentioned and the radial Arm of the rotating nut is in the non-twisted or rear Position while in the front position of the ejector the front face smooth with the front edge of the counter lock can lock and the radial arm in in a twisted or forward position. This rear and forward positions of the ejector respective states of a relative relaxation or tension an elastic spring associated with the ejector is such that this elastic spring the required Drive for the automatic return of the ejector their rear position generated once the trigger of the upper Locking point was pressed against the door frame and the radial arm of the rotatable nut returned to its rear position with other elastic return devices is driven, which is assigned to the nut are.

In the accompanying drawings is a preferred embodiment the new counter lock (2) for the normally inactive door leaves of an emergency door with two door leaves and one Anti-panic device shown. Generally the counter-lock points (2) (Figures 1 and 8) upper and lower locking bars or square bolts (3) or (4) to lock the door wing opposite upper and lower door frame parts not shown on and forms a striking plate opening (5) for the latch (1) Lock that is in the normally active door leaf of the door is installed. Both the lock and the counter lock (2) each have an anti-panic opening function via a push rod, a door handle or a doorknob. At the counter lock the anti-panic opening process simultaneously causes the retraction the upper and lower square bolts (3) and (4) and that Ejecting said trap via an ejection device (6).

To precisely control the positions and movements of the To achieve an edge bolt is a special, simple and effective arrangement of the connecting means of the upper and lower edge bolt (3) or (4) with respective upper (16) and lower (17) slides provided in the vertical direction at the time the ejector (6) is moved in the horizontal direction. Still is a compact and simple device is provided which a Synchronization of the vertical and opposite retraction movements the upper and lower slides (16, 17) and the horizontal displacement of the ejector (6) results.

The connection (Figures 2 to 7) of the upper and lower square bolts (3, 4) with their drive devices achieved that this bolt bolt (3, 4) on the counter lock facing ends with respective thread tips (7) provided, which are screwed into respective nuts (8) fixed in the drive devices of the edge bolt (3,4) are. Here is a self-locking leaf-shaped bracket (9) provided the shape of a by two legs, a first Leg (10) and a second leg (11), formed "U" has, each against first (12) and second (13) end faces the nuts (8) rest, these end faces being the first (12) and second (13) end faces with respect to the forward movement the thread tips (7) when screwing into these nuts (8) are designated. The first (10) and second (11) legs have respective first (14) and second (15) openings that aligned in the axial direction with the bore of the nut (8) are. The first or relatively wide opening (14) has one Diameter, which is suitably slightly larger than that Outside diameter of the thread tips (7), while the second or relatively narrow opening (15) has a diameter, that between the core diameter and the outside diameter of this Thread tips (7).

The thread tip passes through to establish the connection (7) of the upper (3) or lower (4) edge bolt with a suitable one Play the first opening (14) of the first leg (10) the clamp (9) and is screwed into the nut (8) as far as that it projects over the second end face (13) of this mother. Then the thread tip (7) penetrates into the second opening (15) of the second leg (11) and jams when screw in further because the outside diameter of the thread the thread tip (7) larger than the diameter of the second Opening (15) is. When screwing in the thread tip further (7) the second leg (11) is forced into the nut (8), to separate from the second end face (13), at the same time the clamp (9) is opened and pivoted, which is why results in part of the edge of the first opening (14) in the Thread of the thread tip (7) penetrates and at one small additional rotation against the thread of the thread tip (7) jammed. At this apex of handling, a firm and reliable connection evoked its fixing against vibrations caused when the door is opened and in relation to the dead weight of the transom (3,4) ensures.

For fastening the nut (8) is (Figures 2, 6 and 7) provided that this nut (8) two diametrically opposite Has circumferential projections (30) in respective slots (31) project, which are formed in parallel flanges (32) are that of the upper (16) and lower (17) sliders project, which form the drive devices, one the flanges (32) are initially slightly bent to the Attachment of the mother (8) to allow for what this Flange (32) back on to the other flange (32) bends back parallel position.

The vertical retractions of the upper (3) and lower (4) Edge bolt and the horizontal movement of the ejector (6) are preferably by means of (Figures 1 and 8 to 14) rotatable disc (18) related to each other, the three radial guide slots, namely a first (19), a second (20) and a third (21) guide slot, in those in the longitudinal direction respective first (22), second (23) or third (24) bolts are guided, each with the ejector (6), the upper slide (16) or the lower Slider (17) are connected. The ejection device (6) has respective front (25) and rear (26) end faces on the each against the trap (1) or against the outer end of a radial arm (27) come to rest, the non-rotatable with a rotatable nut (28) is connected, which in the implementation of the Opening the counter lock (2) is operated.

A simple view of Figures 1 and 8 makes it possible to recognize that this simple solution is much more compact Constructions that have a large availability in place result in the construction and arrangement of the remaining elements (radial arm (27), nut (28)) facilitates and more convenient dimensions for the housing of the counter lock (2). Farther shows the comparison between Figures 1 and 8 in a clear manner the operation of this simultaneous operation device by means of the disc (18). Figures 9 to 14 show the simple assembly of the disc (18) with respect to the ejection device (6), the upper slide (16) and the lower slide (17).

In order to effect the ejection process, the ejection device moves (6) horizontally between respective rear or rest positions and front or ejection positions, whereby in the rear position mentioned, the striking plate opening (5) the trap (1) can accommodate and the radial arm (27) of the rotatable nut (28) in the non-twisted or rear Position. In the front position of the ejector (6) the front face can be smooth with the front face lock the counter lock (2), and the radial arm (27) is in a twisted or forward position, these rear and front positions of the ejector (6) respective states of relative relaxation or Tension of an elastic spring (29) correspond to the Ejection device (6) and the slides (16 and 17) assigned is.
