Abstract

The invention concerns a closure with a lock casing (2) which can be mounted on a door or window and in which at least one bolt (2.3) is displaceably mounted. The closure further comprises an engagement housing (3) which can be mounted on a frame and into which the bolt (2.3) is introduced in the closed position. A secure key-less lock which is easy to handle is produced in that, in the closed position, the bolt (2.3) engages with an associated holding element (3.5) provided in the engagement housing (3) such that the bolt (2.3) is prevented from being moved by the handle (4.3) into the open position. In order to release the locking connection, an actuating member (3.4) is provided which can be guided out of only one rest position against spring pretension. The bolt (2.3) can only be moved by the handle (4.2) into the open position when the actuating element (3.4) is simultaneously held in its position in which the locking connection is released.

Description

Lock for a door or window

The invention relates to a closure with a lock box that can be attached to a door or a window, in which at least one bolt and one lock between a closed position in which the bolt is moved out of the lock box and an open position in which the Bolt is pushed into the lock box, reciprocating control that can be operated with a handle device are accommodated, and with an engagement housing which can be attached to a frame opposite the lock box and into which the at least one bolt is inserted in the closed position.

Such closures are known, for example, as retrofittable security closures for windows. On the one hand, a lock box with a handle is mounted on the movable window frame in such a way that a bolt which can be moved out with the handle and which is mounted in the interior of the shooting box is moved out to the free edge of the movable window frame, and on the other hand is adjacent to the shooting box on the fixed window frame , an intervention box with an insertion opening for the led bolt mounted. In the firing position, the handle is locked with a key, so that the necessary security against unauthorized opening of the window is provided. It is perceived as a disadvantage that every time you leave the house all locks must be locked with the key.

The invention is based on the object of providing a closure which offers the necessary security without being locked with a key and which ensures easy handling.

This object is achieved with the features of claim 1. According to this, it is therefore provided that the bolt is locked in the closed position on an associated holding element provided in the engagement housing, so that movement of the bolt with the handle into the open position is blocked. To release the locking connection, one against a spring preload from only one Resting position deflectable actuating element is provided and that the latch can only be moved into the open position by means of the handle if the actuating element is simultaneously held in its position which removes the latching connection. When moving the latch with the handle, such as. B. a handle, in the closed position this locks automatically, so that the window or the door from cannot be easily levered out on the outside. To open the breech, the actuating element blocking the latching position must first be deflected counter to the spring preload and held in this position in order to be able to use the handle to bring the bolt back into the open position from the firing position inserted into the engagement housing. In this way, several actuation processes are required at the same time to open the lock, so that an unauthorized person cannot easily open it and a child safety device is also formed. The closed position is also secured. Two alternative Ausgestaltungs¬ possibilities are that the handle consists of a handle mounted on the shooting box and that the actuating element is provided on the lock box, the at least one bolt being spring-biased and deflectable by means of the actuating element and the associated holding element being fixedly arranged in the engagement housing , or that the actuating element is provided on the engagement housing, wherein the at least one holding element is mounted such that it can be deflected against a spring preload by means of the actuating element. The latching mechanism and the locking thus achieved, as well as the release mechanism, are designed in a simple and advantageous manner in this way.

If it is provided that the actuating element is arranged on the upper side of the lock box or the engagement housing facing away from the door, the window or the frame and can be actuated with the hand operating the handle, the actuating element can easily be released simultaneously with the handle ¬ give the lock to be operated. It is advantageous here if the actuating element can be pressed in in a direction perpendicular to the upper side of the engagement housing or the lock box.

A simple construction of the closure and a reliable function are achieved in that the actuating element has a bolt-shaped part with a tapered section and / or a ball on its side facing away from the top of the lock case or engagement housing and that the Actuating element protrudes over the top or in a recess introduced into it.

A clear functioning of the lock is further favored by the fact that the at least one bolt is slidably mounted perpendicularly to the adjacent door or window side in bolt guides of the lock case and in a side lying parallel to the direction of displacement a locking recess with a steep locking flank acting in the opening direction and that the holding element can be deflected perpendicularly to the direction of displacement of the bolt against the spring preload of a spring by means of a locking bevel attached to it and / or on the bolt and can be locked in the locking recess with a steep counter-locking flank in the closed position.

Further advantageous measures for the construction and operation consist in the fact that the at least one bolt engages in the outside of a parallel to the displacement direction, perpendicular to the central transverse plane of the engagement housing and that the latching recess on the side facing away from the central transverse plane The outside of the bolt is arranged such that the holding element assigned to the bolt has a beveled or rounded deflection slope which interacts with the tapered section and past which the tapered section passes while the actuating element is pressed in, so that the holding element with its counter-locking flank comes out of the locking recess ¬ mung is deflected.

A simple, good function ensuring structure, which also offers increased stability and security, is achieved by the measures that the actuating element is arranged in the central transverse plane of the engagement housing on its top, that two holding elements are mirror-symmetrical and perpendicular to each other in corresponding guide receptacles the Verschieb¬ direction of the bars are slidably mounted that the two bars also Mirror-symmetrically to a central transverse plane of the locking box are mounted so that they can be pushed out parallel to it, that the latches are articulated at their end areas facing away from the sliding-out ends to lever-like adjusting elements which are each pivotably mounted on a bearing pin which is fixed with respect to the locking box and on theirs by the other end regions remote from the bolts are articulated and that a control disk is rotatably mounted in the shooting box, which has a control cam into which a coupling element of the two other end regions of the actuating elements engages.

If it is provided that the handle engages in a correspondingly adapted receptacle of the control disk by means of a square piece, the handle being arranged with its axis of rotation in the central transverse plane of the shooting box on the upper side thereof, there are not only advantages in terms of operation and appearance, existing door or window handles can also be used.

In all embodiments, the locking process is possible due to the locking mechanism by actuating the handle alone and only for opening the actuating element and the handle have to be actuated at the same time.

The invention is explained in more detail below using an exemplary embodiment with reference to the drawings. Show it:

Fig. 1 is a perspective view of a closure with a

Lock case and an access housing,

Fig. 2 shows the essential parts of the lock case and the elements and included therein Fig. 3 shows the essential parts of the engagement housing and the elements accommodated therein.

1 shows a closure 1 with a lock case 2 and an engagement housing 3 in perspective. The lock case 2 is mounted on the edge region of a window sash or a door, while the engagement housing 3 is attached to the lock case 2, on a fixed frame section.

The lock case 2 has a case body 2.1 and a case lid 2.2. On the top of the box body 2.1 facing away from the window or the door, a handle 4 is mounted with an attachment 4.1. On the side of the lock case 2 facing the free edge of the window sash or the door, in the closed position of the handle 4, an upper and a lower latch 2.3 are pushed out in the direction of the engagement housing 3 and engage in insertion openings 3.3 of the engagement housing 3. In a central transverse plane of the engagement housing 3 parallel to the direction of displacement of the latches 2.3 and perpendicular to the door or window or frame, an actuating element 3.4 is provided which is accessible from the top of the engagement housing 3 and can be pressed into the interior of the engagement housing 3 perpendicularly thereto. In the shooting position shown, a grip part 4.2 of the grip 4 stands down.

A box body 2.1 of the lock box 2 is shown at the top in FIG. 2. The box body 2.1 has various shapes on its inside, such as two threaded bores 2.1 1, a control disk receptacle 2.5 'for a control disk 2.5 shown further below in FIG. 2, two locking guides 2.3' and two bearing journals 2.6 for receiving two shown below the box body 2.1 Control elements 2.4. The actuating elements 2.4 punched out of flat material, for example, each have openings in the form of elongated holes 2.42 and 2.41 at their two opposing end regions and at their mutually facing end regions, into the connecting bolts 5 for the articulated coupling of the two actuating elements 2.4 on the one hand and coupling of the belts shown on the side gel 2.3 on the other hand. In the present case, the bolts 2.3 are themselves provided with pins 2.31 for articulated connection to the actuating elements 2.4. The actuating elements 2.4 are guided onto the bearing journals 2.6 by means of a respective bearing journal receptacle 2.43 and are pivotably held there. The control elements 2.4 are also shown in a longitudinal section under the top view. The bars 2.3 are provided on their outer longitudinal side facing away from the central transverse plane with latching recesses 2.32 and on the end face with insertion bevels.

Below the actuating elements 2.4, the control disk 2.5 is shown in FIG. 2, which has a control curve 2.51 and an engagement 2.52 for a square, which on the other hand is inserted into the handle 4. The control disk 2.5 is articulated to the receptacles 2.42 of the actuating elements 2.4 with a connecting pin 5, the connecting bolt 5 projecting into the control curve 2.51. When turning the control curve 2.5 by means of the handle 4 and the square projecting into the engagement 2.52, the actuating elements 2.4 held on the two bearing pins 2.6 are pivoted, so that the two bolts 2.3 in the bolt guides 2.31 for taking the firing position out of the lock box 2 guided and retracted to assume the open position in the lock case 2, the direction of displacement of the bolt 2.3 being perpendicular to the front edge of the lock case 2 or the edge of the door or window. The lock case 2 is closed with the case cover 2.2 shown below in FIG. 2, for which purpose screws (not shown) are inserted through lead-through openings 2.21 and tightened in the threaded bores 2.1 1. 3 shows the engagement housing 3 with a housing block 3.1 and a housing cover 3.2. Various receptacles are molded into the housing block 3.1, including two insertion openings 3.3 for the latch 2.3, for two holding elements 3.5, which can be displaced transversely to the direction of displacement of the latch 2.3, for two springs 3.6, which hold the retaining elements in the spring receptacles 3.6 ' 3.5 push together towards the central transverse plane, and an opening 3.8 for a ball 3.42 of the actuating element 3.4. Furthermore, threaded bores 3.9 are provided in the housing block 3.1, into which screws which are passed through screw openings 3.9 'of the cover 3.2 are screwed.

The holding elements 3.5 are inserted into the corresponding receptacles of the housing block 3.1 so as to be displaceable perpendicular to the direction of displacement of the latches 2.3 and pressed against one another by means of the spring 3.6. At their mutually directed end regions, each holding element 3.5 has a deflection slope 3.7, which cooperates with a tapered section 3.43 of the actuating element 3.4 such that when the actuating element 3.4 is pressed in perpendicularly to the upper side of the housing block 3.1, the two holding elements 3.5 counter to the spring force of the springs 3.6 are pushed apart. Likewise, the two holding elements 3.5 are pushed apart when the latches 2.3 are inserted, which slide along with their run-on bevels along corresponding counter-bevels of the holding elements 3.5 until they engage with the holding elements, hook-shaped sections of the holding elements 3.5 in the latching recesses 2.32 of the Engage latch 2.3 and prevent the latch 2.3 from being pushed back into the open position with steep counter-latching flanks, which interact with the steep latching flanks of the latch 2.3. The locking position is shown schematically in Fig. 3 in the second lowest figure. The handle 4 is also blocked against pivoting. Pushing the latches 2.3 back into the open position by means of the handle 4 is only possible if the actuating element 3.4 with the ball 3.42 and the bolt-shaped part 3.41 arranged underneath against the bias of the spring 3.6 and, if appropriate, an additional Lichen (not shown) return spring for moving apart the holding elements 3.5 is pressed. The holding elements 3.5 move outwards and the steep locking flanks of the locking recess 2.32 on the one hand and the counter-locking flanks 3.51 interacting therewith are disengaged.

Alternatively, the holding elements 3.5 can also be arranged fixedly in the engagement housing 3 and the actuating element can be arranged on the shooting box in such a way that when it is actuated, the latches 2.3 are brought out of engagement with the holding elements 3.5 against a spring force. Appropriate scope must be provided in the bolt guide.

Instead of the push-in actuating element with a deflection bevel, an actuating element with a deflection eccentric that can be rotated with a small lever is also conceivable and the latching between holding elements and latch can be achieved with holding elements and / or deflecting elements mounted in a lever-like manner.

The measures described allow simple locking, with only the handle 4 having to be actuated in order to deflect and latch the bolts 2.3. To unlock, however, the actuator 3.4 must be pressed, and at the same time the handle 4 must be operated. A complicated operation with a key is avoided by the described construction of the lock, so that locking cannot be forgotten either. The closure is stable and also safe against considerable leverage. Existing handle elements can simply be plugged on and reused.
