Description

The invention relates to a pivoting latch for a door opener with a door opener housing, wherein the pivoting latch has a latch base body and can be mounted pivotably and lockably in the door opener housing.

Adjustable swivel traps for door openers, especially for electromagnetically actuated door openers, are known. A generic pivoting latch is for example in the DE 196 42 924 C1 disclosed. The pivot latch has on the latch base on an adjustable locking block against which the door leaf-side latch strikes when closing a door. The door opener is installed in a door frame or preferably in two-leaf doors preferably in the passive leaf. To adjust the position of the locking block on the base part of the pivot latch sees the DE 196 42 924 C1 an adjusting screw in front, the screw head is mounted rotatably and axially fixed alternatively in the case base body or in Sperrkloben. The adjusting screw engages with a threaded portion in the other component. About fixing screws of the locking block is fixed in position.

The door opener of DE 196 42 924 C1 has proven itself for many years. However, there are applications in which an increased stability of the door opener against external effects of violence and burglary attempts is desirable. Does it come with the door opener of DE 196 42 924 C1 by force of action to damage or even breakage of the mounting screws, or the locking block is defective for other reasons, the door opener no longer has a component which can interact with the lock latch. The door would open unauthorized in such a situation.

The invention is therefore an object of the invention to provide a pivotal latch, which is characterized by increased security against violence and despite a defective locking block is still functional.

The object is achieved with a pivoting latch for a door opener with a door opener housing, wherein the pivotal latch has a latch base, and is pivotally and lockably storable in the door opener housing, and with a stop at least two divided, so that the pivot latch has a Justieranschlag and a blocking stop, wherein the Justieranschlag and the blocking stop on the trap base are arranged offset relative to each other. Preferred developments are specified in the dependent claims.

The core idea of the invention is a pivoting latch with an at least two-part stop, wherein the stops are offset relative to each other. With a stop is thus hereinafter in the context of the invention, in particular the lock trap stop meant. When closing a door, the latch falls into the lock trap receiving space of a door opener and strikes in the opening direction of the door against the present on the trap body of the door opener stop. According to the invention, instead of the usually one-piece stop, which is designed to stop the latch, an at least two-part latch latch stop is provided on the latch base. By a relative offset of these stops to each other different functions such as adjustment and locking or security functions can be assigned to the respective attacks. The invention is thus characterized by a pivotal latch with functionally graduated stops. Preferably, the Justieranschlag used to set the door opener and the blocking stop as the Justieranschlag downstream safety stop. The blocking stop is arranged in the manner in the door opener that this blocked even with a defective Justieranschlag the latch of a door lock with the door lock engaged and thus maintains the closed state of the door. According to the invention can be ensured by the at least two-part stop thus even with a broken stop, such as a broken Sperrkloben the proper functionality of a door opener with a pivot latch according to the invention, since the latch of a door opener correspondingly arranged door lock now can strike against the at least one blocking stop.

The pivoting latch according to the invention is particularly suitable for integration into a radio door opener. For wheeled door openers, the pivotal latch pivots along the door pivot housing along a pivot axis orthogonal to the pivoting plane. By the comparatively Space-saving arrangement of the functional elements, the pivot latch can be particularly well installed in the housing of a radio door opener.

Preferably, the Justieranschlag is in relation to the blocking stop such a staggered arranged on the pivot latch, that when the door is closed, the latch first strikes exclusively against the Justieranschlag. Due to the offset, the adjustment stop is thus functionally upstream of the blocking stop with respect to the opening position. A functional Vorlagerung the Justieranschlags before the blocking stop has the advantage that only a vote must be made on the Justieranschlag for installation and proper operation of the door opener. Thus, it is particularly preferred if the functionally upstream at least first stop closing and adjusting functions and the functionally downstream second stop has, for example, backup functions.

In a preferred embodiment, the adjustment stop and the blocking stop are arranged side by side on the case base body. This embodiment is characterized by its particularly high operational reliability. Side by side refers to the fact that the adjustment stop and the blocking stop are parallel to the pivot axis of the pivot latch. Preferably, the Justieränschlag and the blocking stop are overlapping in the axial direction of the pivot axis. Alternatively, the components which form the stops, but also interlock and / or overlap. This embodiment is partly advantageous for optical or fire protection aspects.

It is particularly advantageous if the Jüstieranschlag is displaceable on Fallengrundkörper. This embodiment allows a particularly simple installation of the door opener and also allows a quick and easy adjustment of the door opener, for example, changed environmental conditions, as they are observed for example in the so-called bimetallic effect of doors. The adjustment stop can therefore be changed in its positioning and then determined for the operation of the door opener on the trap body.

Preferably, the blocking stop is designed to be more resistant to the influence of corrosion than the adjusting stop or arranged on the pivoting catch. Such an arrangement is characterized by an increased burglary protection or by a superior reliability. For this purpose, on the one hand the blocking stop per se be made of particularly resistant materials, such as special alloys or specially hardened steels. On the other hand, the connection between the blocking stop and the trap base body can be made particularly stable. Here is, for example, the use of special screws made of hardened metals or alloys or even permanent connections such as Verbolzungen, welds, etc. possible.

Furthermore, it is preferable to attach the blocking stop fixed to the case main body. By a stationary connection of the blocking stop with the case main body particularly stable connections and thus particularly safe swing traps can be obtained. Under stationary design are to be understood in this connection types of connection, which are irreversible at least from the moment of installation of the pivoting latch in a door opener. These can be, for example, adhesive, welded or riveted joints.

Preferably, moreover, the blocking stop is formed integrally with the case base body. An advantage of this massive embodiment is the significantly increased stability of the blocking stop with respect to the trap base body. A violent opening of the door, in which a door opener is incorporated with inventive pivoting trap, is considerably more difficult because no weakening connecting element between the blocking stop and the trap base body is present. Furthermore, a one-piece design of the blocking stop with the trap base is particularly advantageous in terms of manufacturing costs and maintenance and care work on the pivoting latch.

Preferably, the pivotal latch has an adjusting stopper and first and second blocking stops, wherein the adjusting stop and the first and second blocking stops are juxtaposed and the adjusting stop is disposed between the two blocking stops, the first and second blocking stops being in alignment. The advantage of this particular embodiment lies in the particularly high stability of the pivotal latch against violence. In the case of a defective Justierfalle the latch strikes simultaneously against the two aligned and functionally identical outer blocking stops, so that the outgoing of the latch bolt forces are distributed to both stops or a punctual load only a blocking stop is prevented. Due to the spacing of the two blocking stops each other, a particularly uniform closing stability of the door latch carrying the pivoting latch according to the invention is also achieved.

Particularly effective is a pivotal latch according to the invention, when two similar blocking stops are arranged on the pivoting latch. Due to the similar design of the blocking stops succeeds in this particular embodiment, a homogeneous force distribution in a failure of the Justieranschlags particularly well. The use of similar blocking stops is over In addition, for the production of a pivoting latch according to the invention advantageous because fewer different components are needed.

In a particularly preferred embodiment, a locking pawl on the pivot latch is present, which has the Justieranschlag, which is connected via a screw connection of a screw and a sliding block with the latch base body, wherein the screw is guided by the locking block and attached to the latch body longitudinal slot, and the sliding block is displaceable on the side opposite the locking block of the case base body and guided in a guide. Due to the arrangement of the Justieranschlags on a locking block, the Justieranschlag itself already an increased stability, so that the overall security of a door opener is increased with inventive pivoting latch. In order to position the locking block and thus also the Justieranschlag on the pivot latch, the locking block is connected via a screw with the case base body. A screw connection has the advantage that it can be solved for adjusting the locking block, with which the locking block can then be moved or moved on the case base body.

For the operation of the pivoting latch, however, it is important that the locking block is fixed and thus the latch can counteract. For this purpose, the screw is tightened and clamped, so that the locking block is fixed in its position on the case base body frictionally and optionally also positively. The use of a screw and slot nut screw connection is particularly user-friendly and reliable. By guiding the sliding block, tilting of the sliding block or unfavorable positioning of the sliding block is prevented. Both the locking block and the case base body therefore have mutually complementary guide means, wherein guide means are to be understood as meaning all devices which enable a defined and at least partially offset movement of the locking block on the case base body.

The movement or displacement of the locking block is carried out, for example stepwise by mutually corresponding positive locking grooves on the locking block and the fallen body. At the contact surfaces between the Justieranschlag (or the adjustment stop forming component) and the Fallengrundkörper directed transversely to the adjustment direction of the Justieranschlags gear teeth, for example in the form of intermeshing grooves, be present. The Justieranschlag and the Fallengrundkörper can then be offset by one or more teeth in the adjustment direction against each other. The adjustment direction in the sense of the invention in this case comprises both opposing displacement directions of the Justieranschlags on Fallengrundkörper. This adjustment is thus designed form-fitting. The teeth are preferably formed in such a way that an adjustment in 1-millimeter increments is possible.

Particularly advantageous, however, is the infinitely variable adjustability of the position of the locking pawl on the latch base body, since in this way a maximum amount of adjustability of the locking pawl is made possible. For this purpose, the fixing of the locking block is non-positively, for example, by tightening a screw, as already described above, which connects the locking block with the Fallengrundkörper. In this variant, the mutually complementary guide means of the locking block and the falling body are usually formed flat or without teeth or the like. The locking block and the fallen body are thus continuously adjustable to each other.

According to FIGS. 1 to 3 the door opener 1 a pivot latch 2, a door opener housing 3, a Justieranschlag 5, a first blocking stop 4, a second blocking stop 6, a Fallengrundkörper 7, a Sperrkloben 8, a bore 9, a contact plate 10, a countersunk screw 11, a sliding block 12 and a slot 13 on.

The door opener 1 belongs to the genus of Radustüröffner, the pivotal latch 2 is also suitable for other types of door opener. Typically, the door opener 1 is installed in a door frame of a single-leaf door, or preferably in the passive leaf of a double-leaf door and cooperates with the latch of a door lock (not shown). The lock latch of the door lock engages with the door closed at least one of the stops 4 to 6.

The door opener 1 has the pivoting latch 2, the Justieranschlag 5, the first blocking stop 4 and the second blocking stop 6, wherein in the illustrated embodiment, the two outer stops, the first blocking stop 4 and the second blocking stop 6, fixed and integral with the Fallengrundkörper. 7 the pivot latch 2 are formed. The two outer stops 4 and 6 are also similar and functionally identical. The mutually spaced stops 4 to 6 are arranged parallel to the pivot axis next to each other and without overlap. The middle adjustment stop 5 is displaceably arranged on the trap base 7, i. the position of the Justieranschlags 5 can be varied and then determined non-positively.

The Justieranschlag 5 is formed by the L-shaped two-legged locking block 8, wherein the one leg of the guide of the locking block 8 is used on the Fallengrundkörper 7 and is in contact with this. The other leg forms the adjustment stop 5, against which the latch strikes in the closed state of the door. To adjust the position of the Justieranschlags 5 of the locking block 8 is from an extended position in which it is flush with the first blocking stop 4 and the second blocking stop 6, so that the blocking stops 4 to 6 are aligned, orthogonal to the pivot axis of the pivot latch 2 displaceable. Accordingly, the locking block 8 in the Fig. 1 to 3 shown in a retracted position, so that the adjustment stop 5 is arranged laterally offset from the first blocking stop 4 and the second blocking stop 6. The locking block 8 is thus shifted against the opening direction of the door (arrow direction of the arrow A). In this illustrated embodiment, a latch with the door first hits against the functionally upstream Justieranschlag 5, wherein the first blocking stopper 4 and the second blocking stopper 6 are non-contact with the latch. The blocking stops 4 and 6 are the adjustment stop 5 thus functionally downstream in the opening direction of the door.

If in the event of a violent attempt to open the door should break the locking block 8 from a certain violence, the adjustment stop 5 of the locking block 8 would not be able to retain the latch of the door in the closed state. In this situation, the latch now strikes the downstream first blocking stop 4 and the second blocking stop 6. These are due to their integration in the case base body 7, which are present in total as a component, much more stable than the locking block 8. This prevents opening of the door despite defective locking block 8.

To realize the door opener function, it is possible to swing the pivot latch 2 remotely into the door opener housing 3. Fig. 3 shows the pivot latch 2 in pivoted in the door opener housing 3 state. For this purpose, the door opener 1 corresponding control devices and connections for power and signal supply (not shown). In addition, in the Fig. 1 to 3 illustrated preferred door opener 1 is provided with a contact plate 10, which is pressed with the door closed by the latch in the direction of the door opener. Typically, the contact plate 10 is part of a potential-free changeover contact and serves, for example as a feedback contact to ensure the closed state of the door for example, a closing control system.

For attachment and fixation of the locking block 8 on the case base body 7, the pivotal latch 2 has a screw connection. The screw is composed of a countersunk screw 11 and a sliding block 12 together. The countersunk screw 11 is guided by a conical bore 8 mounted in the locking bolt 8 and engages on the locking block 8 opposite side of the Fallengrundkörpers 7 in the sliding block 12. The conical bore is almost centered on the standing with the Fallengrundkörper 7 in contact part of the Sperrklobens. 8 appropriate. The adjacent to the locking block 8 Fallengrundkörper 7 has to guide the countersunk screw 11 a slot 13. The slot is arranged such that the countersunk screw 11 can be guided along the pivot plane of the pivotal latch 2 by the latch base body 7, wherein the countersunk screw 11 can be moved along the slot 13 in the pivoting plane of the pivoting latch 2. The Fig. 2 and 3 show that the tip of the countersunk screw 11 engages in the sliding block 12, which is guided on the locking block 8 opposite side of the case base body 7.

To lock the Sperrklobens 8, the countersunk screw 11 is tightened and clamped. For this purpose, the sliding block 12 has an external thread (not shown) of the countersunk screw 11 corresponding internal thread (not shown). The sliding block is guided along guides 14, which run parallel to the longitudinal extent of the elongated hole 13. The described screw connection structure is particularly advantageous, in particular with regard to the stability of the locking of the locking block 8, but also with regard to wearing parts. Thus, this particular arrangement allows complete replacement of the Verschraubungsmechanismusses without having to replace other components of the door opener 1. This is particularly advantageous for doors in which frequent adjustment of the locking block 8 is required.

From the 4 to 6 the detailed structure of the pivotal latch 2 shows. The trap base body 7 is mounted in the door opener housing via a bolt (not shown) which runs through the bore 9, which runs coaxially to the pivot axis of the pivoting latch 2. Furthermore, the trap base body has the first blocking stop 4 and the second blocking stop 6, which project from the latch base body 7 in the manner of a hook or protrude away from the surface of the trap base body at a right angle to the stop faces facing away from the opening direction of the door. In addition, a slot 13 is centrally attached to the case base body 7, through which the countersunk screw 11 of the screw is guided. According to the invention, the pivoting catch 2 further comprises an adjusting stop 5, which is formed by the locking block 8 and is displaceably arranged on the latching base body 7. To connect the locking block 8 with the case base body 7, the countersunk screw 11 of the screw through the locking block 8 is performed. For this purpose, the locking block 8 has a conical bore which is formed corresponding to the countersunk head region of the countersunk screw 11. Further, the countersunk screw 11 is guided through the slot 13 of the case base body 7 and engages from the direction of the Sperrklobens 8 behind the slot in a provided with an internal thread (not shown) bore in the sliding block 12 a. Fig. 4 shows a guide area in the case base body 7, along which the sliding block 12 can be moved.

Fig. 6 To lock the locking block 8 to hold the Justieranschlag 5 ultimately in a fixed position, the countersunk screw 11 is tightened, so that a frictional connection between the locking block 8, the Fallengrundkörper 7 and the sliding block 12th is reached.
