Description

Driven bolt lock

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

Generic drive bolt-locks are already known. From the DE3535344A1 For example, it is already known to provide a drive bolt shift shell in which a trigger latch is provided with a sloped contact surface and a stepped latch tail. A cylindrical portion of the latch tail passes through a guide, on which a latch spring is supported and penetrates with a stepped smaller by a phase of the tail tail diameter shaft. A tapered end portion passes through a cross slide, which is associated with a stop of the drive bolt. The phase of the trap tail is arranged so that it attacks at Gehäuseeinwärts displaced trap at an edge of the cross slide and releasably displaced the shoot bolt. The control is accordingly on the slope surfaces of the phase of the tail tail. The disadvantage is the multi-part design and that the case must be adapted to the respective opening direction.

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. Also envisaged is a lockpipe also penetrating and under spring force switching latch, which is to press on impact with the door frame and thereby pivots 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 im Lock housing accommodated clamping plate, which allows the drive bolt not only in its fully retracted position but to block it in any other Einfahrstellungen. 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 out of the locking recess with the locking arm and the spring-loaded latch closes.

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

To solve this problem, the invention provides that the release means consists of a displaceable in the direction of movement of the drive bolt on the lock plate protruding button, which is associated with the blocking element on a plane inclined to the direction of displacement first surface. Locking element and buttons are therefore independent components that can be arranged spatially spaced from each other. Here are the used funds easily procured and easy to produce and cause the required movement path with a small size. According to the invention, the probe has a spherical shape and interspersed with a spherical segment section in a castle cuff direction conically narrowing hole whose light breakthrough is dimensioned transversely to the castle cuff extension smaller than the ball diameter. This embodiment requires a particularly simple and at the same time effective embodiment, since the spherical surface of the probe in conjunction with the inclined surface of the blocking element forms an ideal translation, which leads to a relatively large movement of the blocking element with little movement of the probe.

It is also advantageous if the inclined first surface opposite a mirror image of the first surface inclined second surface of the lock housing and the button is movably mounted between these surfaces. The floating support of the spherical button between the inclined surfaces ensures sufficient advance of the ball segment.

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.

Further advantageous embodiments will be apparent from the drawings. It shows:

• Fig. 1 a schematic overview of a two-leaf door with a floating bolt latch,
• Fig. 2 the drive bolt lock and associated therewith espagnolette fitting,
• Fig. 3 a longitudinal section of Fig. 2 with deactivated blocking element, and
• Fig. 4 a cut accordingly Fig. 3 with activated locking member.

In the Fig. 1 is designated in the schematic representation with 1 of the moving leaf with 2 of the inactive leaf and with 3 of the frame. An attached to the inactive leaf 2 espagnolette 4 can be operated via a pusher 5. In this case, deviating from the illustration, a folding lever mounted in the fold between the aisle and inactive leaf 1, 2 can be provided, which is accessible only when the active leaf 1 is open.

The inactive leaf 2 can be fixed to the frame 3 with the active leaf 1 open via the latch component 6 and its latch 7. The latch 7 engages in a closing opening of a frame-side striking plate, which in turn projects in the direction of the inactive leaf 2 Cam 8 carries. 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 the Fig. 2 Details of the locking member 6 can be seen. Thus, the latch 7 does not precede the open wing 2 in its locking position, 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.

The locking member 6 is drivingly connected to a coupling 11 on the drive rod 9, not shown here. 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. 2 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.

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 a drive rod 9 of the espagnolette lock 4. The drive rod 9 is federkraftschlagt and in the in the Fig. 3 shown locked position urged.
The bolt 7 passes through a passage opening 16 of the lock plate 13, which takes place in the illustrated embodiment at a located between the lock housing 12 and the locking member 6 gap 17, in which the activated locking element 15 accordingly Fig. 4 protrudes. This eliminates the need for a corresponding production of the passage opening 16 and on the other hand, the claimed space is reduced.

From the synopsis of Fig. 3 and 4 It can be seen that the activated blocking element 15 dips into the recess 7 'of the bolt 7 and is mounted displaceably in the lock housing 12 substantially transversely to the direction of movement of the bolt 7. 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 blocking element 15 is the triggering 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 first surface 20.

As can be seen from the figures, the probe 19 has a spherical shape interspersed with a spherical segment portion 21 in the direction of Schlossstulps 13 conically narrowing bore 22. In this case, the clear diameter 23 of the bore 22 is dimensioned at least transversely to the Schlossstulp extent smaller than the ball diameter, so that an escape of the button 19 is excluded in this direction. In the opposite direction of the button 19 is located on the inclined first surface 20 mirror-inverted opposite inclined second surface 24 of a mounted in the lock housing base plate 25 at. Due to this arrangement, the button 19 is movably mounted between these surfaces 20, 24 and is due to the Federkraftbeaufschlagung and the funnel-shaped receptacle in the in Fig. 4 situation urged.

The spherical shape of the probe 19 and its storage within each transverse surfaces 20, 24 and the tapered edge of the bore 22 cause on the one hand a freely rotatable low-friction mounting of the probe 19, which makes no additional fasteners required. In this case, the inclined surfaces 20, 24 in conjunction with the spherical 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.

The lock housing 12 and / or the lock face 13 consist of a substantially U-shaped profile section in which the base plate 25 leading the locking element 15 is received. On the base plate 25, the compression spring 18 is supported. The base plate 25 and the lock plate 13 are connected to one another via a screw 26.

The function of the drive bolt latch 10 is apparent from the FIGS. 3 and 4 , When the inactive leaf 2 is closed, the button 19 is urged over a frame-side stop, not shown here, into the space 27 resulting between the lock plate 13, the base plate 25 and the blocking element 15, resulting in a displacement of the blocking element 15 in the Fig. 3 leads to the left. As a result, the blocking element 15 is outside the range of displacement of the bolt 7, which is released and conditionally preceded by his outgoing from the espagnolette lock 4 Federkraftbeaufschlagung.

If the latch 7 is withdrawn by actuation of the espagnolette lock 4 and the fixed leaf 2 is swung out of the frame 3, then the button loses its support in the free space 27 and is due to the action of the compression spring 18 in the Fig. 4 pushed up. The blocking element 15 which moves with the surface 20 is displaced to the right and, with its end facing the latch 7, projects past the end of the lock housing 12 and engages behind one of the locking edges 28, 29.

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 28, 29.
