Description

The invention relates to a drive bolt lock mechanism according to the preamble of claim 1.

The DE 3535344 A1 discloses a lifter bolt latch in which an auxiliary latch projects beyond the latch cuff and is displaced perpendicular to the crease when the blade is closed by the frame. The auxiliary trap has on its tail tail a conical taper, which is associated with a recess of a blocking element. In the activated state of the locking element, the thickened portion of the latch tail enters into opening, which is thereby withdrawn from the drive bolt. In the deactivated position, ie with the sash open, the auxiliary latch is urged by a spring in front of the forend and the conical taper engages with the smaller diameter portion of the opening in the locking element, which thereby kraftbeaufschlagt via a second spring can reach its locking position. The design requires in addition to several components and a large amount of space that must be created by a recess.

The JP S528097 U shows a Treibriegelschaltschloss in which the biased into its closure position drive bolt is held by a trigger. The trigger is a pivotally mounted in a housing two-armed lever which abuts against the frame via a first arm and thereby pivoted so that its second arm releases a stop of the drive bolt. As a result, the drive bolt is released and locked. In order to realize the embodiment, the first arm has to abut on the frame visible surface of the frame, which leads to actuating tracks. In addition, the space of the pivotable perpendicular to the frame plane lever is large and requires a corresponding to be made or existing cavity design.

Generic drive bolt-locks are already known. In the from the EP 0859106 B1 Known floating bolt lock the lock plate has a bore which forms a passage opening for a spring-loaded in the direction of its extended locking position drive bolt. It is also provided on the lock housing a spring-loaded clamping plate which surrounds the drive bolt with a clamping eye and to block it in any Einfahrstellungen allowed. Provided is also the castle cuff also penetrating and under spring force switching latch, the at Pressing impingement on the door frame is pivoted while the clamping plate in their release the floating bolt release position.

Treibriegel switch locks above type are also by the DE-PS 2746049 and DE-PS 2912881 known. They are usually installed in the passive leaf double-leaf doors, z. B. according to the DE-GM 8701630 to ensure that the spring-loaded floating bolt is held in its unlocked position with the sash open and only extends into its locking position after the inactive blade has reached its closed position. In this case, then engages the drive bolt with its outer end in the Schliessloch a present on the fixed door frame Schliessblechs, which also serves as a stop for the switching latch. Particular importance is attached to the housed in the lock housing clamping plate, which allows the drive bolt not only in its fully retracted position but also in any other Einfahrstellungen to block. This is important because the Treibriegelstangen not always necessarily have to be fully retracted, for example, large door-folding air. The above-described known switching locks but are still comparatively bulky in design, since they have a conventional trained as a rectangular box lock housing, in which the drive bolt and the switch latch are at a distance next to each other and also require a correspondingly long trained clamping plate. The installation of these known switching locks therefore also requires correspondingly large recesses in the door leaf, usually at the upper wing corner, which is problematic especially in tubular frame doors. Namely, the latter consist of tubular profiles that are mitred and connected to each other via special corner reinforcements. But here, the drive bolt lock mechanism must be installed, which is not only associated with difficulties, but also brings a corresponding weakening just this corner reinforcement with it. Similar embodiments can be found in the EP 0635611 B1 and the EP 1201853 B1 ,

In the from the EP 0859106 B1 Known floating bolt lock the cylindrical drive bolt is received in a clamping sleeve, which in turn is received in a conically tapered sleeve on the inner diameter. The outer sleeve can be relocated via a button relative to the clamping sleeve, so that the drive bolt is released when the button is pressed by engagement with the frame.

From the DE-PS 75175 a lock has become known with an auxiliary trap, the latch is released when pressed back auxiliary latch. For this purpose, the inclined to the latch and limited pivotally mounted auxiliary latch on a locking arm, which is attributable to a locking recess of the bolt. If the auxiliary latch is inserted against a return spring, it pivots this with the locking arm from the locking recess out and the spring-loaded bolt closes.

The invention is therefore based on the object to enable a safe and reliable release of the drive bolt with minimal space.

To achieve this object, the invention provides that the activated locking element is immersed in a recess of the drive bolt, and that only the urging the blocking element in the activated position compression spring over the surfaces of the provision of the button is used. Locking element and buttons are therefore independent components that can be arranged spatially spaced from each other. The funds used are easy to procure and easy to manufacture and cause the required movement with a small size.

A further embodiment provides that the button has a pointed wedge shape and passes through a hole in the lock plate with its roof-shaped end. This embodiment allows a symmetrical configuration of the probe, so that the drive bolt latch can be used for right and left pivoting wings.

To simplify the production of the drive bolt latching mechanism, it is provided that the lock housing and / or the lockthruster consists of a substantially U-shaped profile section, in which a base plate guiding the blocking element is received.

In order to achieve an offset arrangement of the bolt relative to the espagnolette lock, it is provided that the drive rod of the espagnolette lock is associated with a coupling member for connection to the latch. This also ensures that the adaptation of the bolt can take place in or near the upper edge of the wing.

A simple embodiment, which also allows easy adjustability of the bolt, provides that the coupling member has a threaded bore for coupling with a cylindrical rod of the locking member.

If the rod of the locking member is associated with a flat rectangular latch, then in connection with a shape adapted to the bolt passage opening in the drive bolt latch lock anti-rotation is achieved.

In the Fig. 1 is in the schematic representation of an attached to a passive leaf of a two-leaf door espagnolette with 4 designated can be operated in a known manner via a pusher, not shown here.

The inactive leaf can be fixed to the frame even when the active leaf is open via espagnolette lock 4 and the latching component 6, which is coupled thereto in terms of movement, and its latch 7. The latch 7 engages in a closing opening of a frame-side locking engagement 30, which in turn carries a projecting in the direction of the inactive cam. The locking member 6 is coupled via a drive rod 9 with the espagnolette lock 4 and is drivingly connected thereto. The drive rod 9 and thereby also the rigid drive-connected latch 7 are spring-loaded as a result of the design of the espagnolette lock 4 in the closing direction.

In particular, in doors whose wings are composed of hollow sections, there is a need to maintain available in the corner region of the abutting hollow profile bars corner joint and reinforcement machining and not to weaken. Therefore, the drive rod 9 is associated with a coupling member 31 which transmits the movement of the drive rod 9 in an offset plane. For this purpose, the coupling member 31 protrudes from the back of the drive rod 9 and the locking member 6 couples thereto in a recording.
This also ensures that the adaptation of the bolt can take place in or near the upper edge of the wing. In order to allow easy adjustability of the bolt 7, it is provided that the coupling member has a threaded bore 7a for coupling with a cylindrical rod 7b of the locking member. The rod 7b may be formed as a threaded rod. The cylindrical rod of the locking member is associated with the flat rectangular or a flattened at opposite longitudinal edges bar 7. The bolt 7 and the rod 7b are coupled via a threaded connection. Deviating from the illustration, the coupling member may also be arranged in the secondary lock box.

In the Fig. 2a and 2b Details of the locking member 6 can be seen. Thus, the latch 7 does not precede in its locked position with open wing, which would lead to the damage when closing the passive leaf, this can be fixed in its deactivated, ie retracted position. For this purpose, the latch component 6 is assigned a drive bolt latching mechanism 10.

In the exemplary embodiment, the floating bolt lock 10 is assigned to the locking component 6 on the upper edge remote from the rotary axis. However, it may also be attached to the opposite lower wing edge, if necessary, in addition. It is in the Fig. 2b recognizable that the drive bolt latch 10 has a substantially flat rectangular lock housing 12 and that a lock plate 13 forms an upper housing closure. About this lock plate 13 projects a trigger means 14 before. It is also a located on the back of the bolt 7 recess 7 'recognizable. This recess 7 'forms horizontally extending blocking edges.

In the FIGS. 3 and 4 is in longitudinal section respectively the deactivated position of a blocking element 15 (FIG. Fig. 3 ) and its activated position ( Fig. 4 ).
The cross-sectional flat rectangular latch 7 is, as already stated above, drive-coupled via the coupling member 31 to the drive rod 9 of the espagnolette lock 4. The drive rod 9 and thereby also the bolt 7 of the locking member 6 are spring-loaded and in the in the Fig. 2a, 2b shown locked position urged. The bolt 7 passes through a passage opening 16 of the lock plate 13 and the lock housing 12, wherein in the illustrated embodiment, a guide extension 32 is provided on the lock housing 12 on the underside.

From the synopsis of 3 and 4 It can be seen that the activated locking element 15 protrudes into the passage opening 16 of the bolt 7 and is mounted displaceably in the lock housing 12 substantially transversely to the direction of movement of the bolt 7. The passage opening 16 is adapted with play to the cross-sectional shape of the bolt 7. As a result, the latch 7 is mounted against rotation on the drive bolt latching mechanism. In this case, the blocking element 15 is subjected to force by means of a designated 18 and designed as a compression spring force storage device in its activated position.

The locking element 15 is associated with the release means 14, which consists of a displaceable in the direction of movement of the bolt 7 on the lock plate 13 protruding button 19 which is associated with the blocking element 15 at an inclined to the direction of displacement R extending first surface 20.

Evidently the Fig. 5 the button 19 has a pointed wedge shape, the roof-shaped end 33 of the Schlossstulps 13 tapered conically over and this passes through in an opening. In the opposite direction of the button 19 is located on the inclined first surface 20 at. The inclined surface 20 is pulled down to a horizontal web 34 in the illustrated embodiment. At this web 34, the button 19 is in its depressed position. Due to this arrangement, the button 19 is movably mounted between the surface 20, and the web 34 and is due to the Federkraftbeaufschlagung of the blocking element 15 and in the in Fig. 4 situation urged.

Contributing to this is that the probe 19 rests against the inclined first surface 20 with a chamfer-like second surface 35. The obtuse meeting of surfaces is thereby avoided. The urging the blocking element 15 in its activated position spring 18 also serves to return the button 19th

The roof shape of the button 19 and its means of symmetrical mounting in the lock housing 12 allow use of the drive bolt latch 10 on the right and left wings.

In this case, the inclined surfaces 20, 35 in conjunction with the roof shape of the probe 19 also lead to a despite the low ability of the push button 19 large stroke of the locking element 15. This allows a pinpoint sensitive retraction of the locking element 15 at a minimum height, which is also ensured in that the latch 7 is not released until the frame-side latch inlet opening and the passage opening 16 lie opposite one another. Due to the fact that the blocking element 15 is always subjected to spring force, adjustment or adjustment work is unnecessary because of the relative position of the blocking element 15 relative to the latch 7.

The lock housing 12 consists of a substantially U-shaped base plate 25 in which is guided in the locking element 15 and on which also the compression spring 18 is supported. The base plate 25 and the lock plate 13 are firmly connected.

The function of the drive bolt latch 10 is apparent from the FIGS. 3 and 4 , When the inactive leaf is closed, the button 19 is urged by a frame-side stop, not shown here in the extending between the lock plate 13, the base plate 25 and the locking element 15 space 27, resulting in a displacement of the locking element 15 in the Fig. 3 leads to the right. As a result, the blocking element 15 is outside the displacement range of the bolt 7 and is moved out of the passage opening 16, whereby the latch 7 is released and due to its by Espagnolette lock 4 outgoing spring force locking the inactive leaf.

If the latch 7 is withdrawn by actuation of the espagnolette lock 4 and the fixed leaf pivoted out of the frame, then the button 19 loses its frame-side support in the free space 27 and is due to the action of the compression spring 18 in the Fig. 4 pushed up. The with the surface 20 nachrückende blocking element 15 is displaced to the left and occurs with its the latch 7 facing the end in the passage opening 16. The required to open the passive leaf retracted position of the bolt 7 is fixed.

It is readily apparent that the blocking element 15 can also cooperate with the dull end of the bolt 7, so that it requires no special embodiment of the bolt 7 or locking edges.

The blocking element is essentially Z-shaped, so that a stop cooperating with a projection of the base plate 25 results, which limits the blocking element 15 in the unassembled state in its pre-emergence.

The lock housing 12 is designed angular for ease of assembly and thereby engages the wing edge zwekelnkelig, which facilitates the location assignment to the espagnolette lock 4 and the frame-side locking engagement 30.
