Description

The present invention is directed to a lock for a door, a window or the like, with a lock housing, in which a locking mechanism is received with a locking element and a driving element, which cooperates with a lock cylinder. The locking mechanism further comprises a selector element, which is movable between at least two selector positions for the conversion of the functional properties of the lock.

Locks of this type have a lock housing to receive a locking mechanism, which according to the present invention, each mechanical element is understood as part of the locking mechanism. Consequently, the locking mechanism comprises at least one locking element, which can be understood as a door latch, as a door latch or as a door bolt. The locking element is formed with a mechanical connection to the driving element, which is rotatably received within the lock housing and which is designed for an operative connection with the lock cylinder. Consequently, the driver can be rotated by the rotation of a key which is inserted in the lock cylinder. The rotational movement of the driver element permits retraction of the latch member from a protruding position to a retracted position of the latch member into the lock housing to open the door or window made with the lock.

In addition, locks are known in which a selector element is integrated. The selector element is intended to change the functional properties of the lock, whereby the operation of the movement of the selector element is carried out manually. The Lock housings are usually formed with a forend, and the selector element has an operating element which extends through the forend and is manually movable. The functional properties of the lock may relate to a determination of the door latch or door handle or it is possible to influence the behavior of the lock mechanism. The selector element is switchable between different selector positions, wherein at least two positions are provided, into which the selector element can engage.

The patent FI 876 82 discloses a door lock with a lock housing, which is designed with a forend and a locking element. In addition, a driver element for operation with a key is provided as part of the locking mechanism, wherein force transmission means for a manual movement of the locking element from a protruding closing position to a retracted position are known. Furthermore, the lock housing on a selector element for the conversion of the functional properties of the castle. Disadvantageously, the lock is formed with a closing member which is movable only by the power transmitting means in conjunction with the operation by a key from a blocking position in which the movement of the selector element is prevented, and a release position in which the movement of the selector element is allowed is. This means that a key is necessary to change the selector position of the selector element. Furthermore, a key for rotation of the driver element is required, which must be held with a first hand, wherein the selector element must be moved manually with a second hand. Consequently, two hands are necessary to change the selector position.

It is therefore the object of the present invention to provide a lock with a locking mechanism which has a selector element which can be easily operated and has a safety release arrangement to prevent an automatic changeover of the selector position.

This object is achieved by a lock with a selector element according to the teaching of claim 1 of the present invention. A preferred embodiment of the present invention is defined by the subclaims.

The invention includes the technical teaching that the movement of the selector element is independent of the driver element executable, wherein release means are provided for interacting with the selector element, such that the release means must be activated before the selector element is displaceable between the selector positions.

According to the invention, a mechanical locking system for blocking the selector element via the driver element is avoided. The selector element can be changed without an operation of the driver element, which means that a key for rotation of the lock cylinder is not necessary. The person who is provided to operate the selector element does not need a key for the lock, but this must activate the release means. The release agent must be activated in advance before the selector element is displaceable between the selector positions.

According to a first embodiment of the invention, the release means comprises a pin element as part of the locking mechanism, which is arranged in a cuff, which is the front side of the lock housing forms. The pin member protrudes from the forend and is manually movable between an engaged position and a release position. The pin element is designed for vertical impressions in the forend. The protruding position of the pin element forms the engagement position, and the selector element is not switchable between the Selektorpositionen. When the pin member is pushed vertically into the forend, the release position is reached and the selector member can be switched between the selector positions.

According to a preferred embodiment, the forend extends in the mounted state along the vertical direction of the lock housing on the front side, wherein the selector element is movable parallel to the extension direction of the cuff. Consequently, the position of the selector element can only be changed when the door or the window is open. Otherwise, the pin element would not be reachable. Usually, the extension of the cuff is arranged in the vertical direction with respect to the vertical extent of the door leaf, and the selector element can be moved between an upper, a middle and, for example, a further lower position.

A further embodiment of the present invention provides a pin element which is movably received in the selector element, wherein the direction of movement of the pin element is aligned perpendicular to the direction of movement of the selector element. The selector element is designed with a hole into which the pin element is inserted. The displacement of the pin element is guided through the hole in the selector element, so that the pin element is guided when it is pressed into the forend. Consequently, the face plate and the selector element are arranged close to and parallel to each other. If the selector position is to be changed, a person must manually push the pin element into the selector element, and must do so Switch selector element between positions while holding the pin member in the depressed position.

The present invention is also embodied with a closing mechanism which has a stop element for blocking the movement of the selector element via a positive locking geometry. The positive engagement geometry includes stop bars and a hook shape disposed between the selector element and the stop element, the hook shape being adapted to engage the stop bars.

The positive connection between the stop element and the selector element prevents the displacement of the selector element when the hook shape engages in the stop bars. Each stop button forms a specific selector position, and the number of selector positions corresponds to the number of stop pins into which the hook shape of the selector element can be inserted.

According to a first arrangement, the hook shape is designed as part of the selector element, while the stop bars are each formed as part of the stop element. According to a second arrangement, the hook shape is designed as part of the stop element, while the stop bars are formed as part of the selector element. The stop bars and the hook shape can be designed as individual parts, wherein the hook shape and the stop bars are made in one piece with the selector element or with the stop element.

The stop member is pivotally received by a pivot axis within the lock housing, the pin member having a pressure side disposed adjacent to the stop member. The pressure side of the pin member is disposed opposite from the side of the pin member which extends through the forend and to which it can be manually pressed. If that Pin element is pressed through the hole in the selector element, the pressure side pushes the stop member in the release position, while the stop member pivots about the pivot axis. Only when the pin element is pressed into the forend, the positive connection between the hook shape and the associated stop stamp is released and the selector element can be switched between the Selektorpositionen.

According to a preferred embodiment, the selector element is designed with at least one notch to cooperate with a detent element. The latching element is arranged in a stationary position within the lock housing and has a latching nose for engagement in the notches on the selector element. The selector element can only be moved in the direction of change between different selector positions. Consequently, the selector element forms a stationary part with respect to the direction of movement of the latching element, wherein the latching element and in particular the latching lug forms a movable part. The latching notches within the selector element are formed in a wave structure and the latching lug can slide along the wave structure. The latching effect is based on a spring-back effect of the latching element, wherein a preferred material of the latching element comprises a synthetic material such as a plastic. The wave structure comprises wave crests and wave troughs, the wave troughs corresponding to the assigned selector positions into which the selector element has to engage. Due to the spring-back effect of the latching lug, the latching lug can slide along the shaft structure and firmly locks the selector element in the assigned selector positions.

According to a further embodiment, the forend has a recess into which the pin element is inserted, wherein the recess has an elongate shape in the extension direction of the cuff.

Within the recess, the pin element can be displaced along the elongated direction. Even if the pin member extends through the forend and is not pressed into the forend, it is received within the recess to allow closing of the door or window into which the lock is received, since the pin member does not cover the whole Castle stands out.

Another embodiment of the present invention provides a selector element which cooperates with a mechanical arrangement or with an electrical arrangement. The selector element can be designed to block the door latch, the door handle or the lock cylinder. Furthermore, the lock may comprise an electrical arrangement, which may be designed as an electrical switching element, as an electrical actuator or as a sensor element for detecting the functional properties of the lock with respect to the switching state. Thus, the selector element may comprise mechanical-electrical interaction means.

Another preferred embodiment of the present invention includes release means for interacting with the selector element, which are embodied as at least one electrical actuator that cooperates with the stop element to change over the engagement situation between the hook shape and the stop rules. The electric actuator may be operable by an external control unit to enable or disable manual operation of the selector element. Consequently, the electric actuator may act as an alternative to the pin member, and the switching of the selector element between the various selector positions may be carried out via a remote control unit. In buildings with a large number of different doors with associated door locks, a central control unit may be adapted to control the release of the selector element changeover between its positions.

Fig. 5

shows a further perspective view of the lock with a locking mechanism having a locking element which interacts with the selector element.

FIG. 1 shows a plan view of the lock 1 according to the present invention. The lock 1 comprises a lock housing 2 with the top cover removed to show the lock mechanism is received within the lock housing 2. The locking mechanism has a locking element and a driver element 4, wherein the locking element (not shown) in the lock housing 2 by a turning of the driver element 4 is retractable. The locking mechanism comprises a selector element 5 which is displaceable between different selector positions A, B and C, wherein the selector element 5 is shown in its position A. Depending on the selector position A, B or C, the lock 1 may have different functional properties, which may relate to a blocking of the mechanical connection between the driver element 4 and the locking element, a blocking of the door latch, etc.

The displacement of the selector element 5 can be effected by an activation of the release means, which comprises a pin element 6, which can be understood as part of the closing mechanism and which is arranged in a face plate 7, which forms the front side of the lock housing 2. The pin member 6 protrudes from the forend 7 and is manually movable between an engaged position and a release position, wherein the pin member 6 is manually pressed into the forend 7 vertically. Consequently, the pin member 6 is movably received within the selector element 5 via a hole, and the direction of movement of the pin member 6 is aligned perpendicular to the direction of movement of the selector element 5, which corresponds to the extension direction of the Stulpes 7. In the figure, the pin element 6 is not pressed into the forend 7 and the selector element 5 is not displaceable between the selector positions A, B and C. The pin member 6 includes a pressure side 6a for abutting a stop member 8 which is pivotally received within the lock housing 2 via a pivot axis 10 and which pivots to the release position by manual pressure on the pin member 6. A spring element 13 biases the stop element 8 into an engagement position with the selector element 5. The engagement arrangement blocks the Movement of the selector element 5 via a form fit geometry. The interlocking geometry comprises a plurality of stop bars 8a and 8b, wherein more than two stop bars 8a, 8b may be provided. The selector element has a hook shape 5a, which is designed to engage in the stopper bosses 8a or alternatively 8b. In the figure, the hook shape 5a is engaged with the stopper boss 8a, and the selector element 5 is set at the selector position A. Consequently, the selector position A can not be switched to the selector position B or C.

In FIG. 2 is a plan view of the lock 1 according to the FIG. 1 shown, wherein the release means to enable the selector element 5 are activated. The pin member 6 is pressed into the forend 7, and the stopper member 8 is pivoted about the pivot axis 10 against the spring tension of the spring element 13 via the pressure side 6a. In this arrangement, the selector element 5 is displaceable between the selector positions A, B and C, since the positive connection between the selector element 5 and the stop element 8 is not engaged. As shown, the hook shape 5a of the selector element 5 does not engage in one of the stopper bosses 8a or 8b of the stopper member 8. The release of the selector element 5 is made possible without a rotation of the driver element 4, since only the pin element 6 has to be pressed into the forend 7. As further shown, the pin member 6 is designed as part of the release means and as an actuator for switching the selector position. As a result, only one hand is necessary to change the selector position without the use of a key to rotate the driver element 4.

FIG. 3 shows the lock 1 with a selector element 5, which is arranged in the selector position B. The pin element 6 is pressed into the forend 7 and received within a recess 9, which forms an elongated shape within the Stulpes 7. The hook shape 5a is not with the stopper 8a or the stopper 8b engaged, and the selector element 5 is parallel to the extension direction of the Stulpes 7 movable.

According to the FIG. 3 For example, an electrical actuator 12 is shown in an exemplary manner that forms another release means and that is intended to cooperate with the stop member 8. The electric actuator 12 may be embodied as a lifting magnet having a connecting armature in order to form a connection between the stop element 8 and the electric actuator 12. When the electric actuator 12 is activated, the stop member 8 can be pivoted about the pivot axis 10, and the selector element 5 is released for switching the selector position A, B or C without pressing the pin member 6. The position of the electric actuator 12 within the lock housing 2 is shown by way of example only and may be positioned within the lock mechanism in any other manner.

FIG. 4 shows a perspective view of the lock 1, comprising a locking mechanism with a locking element 3, which is shown in a protruding position. Further, the hook shape 5a is shown on the selector element 5, which engages in the stopper 8b of the stop element 8. Furthermore, the pivot axis 10 is shown for pivotally receiving the stop element 8 within the lock housing 2. In addition, the parallel arrangement of the selector element 5 to the forend 7 is shown, wherein the direction of displacement of the selector element 5 is indicated by a double arrow. Furthermore, the driver element 4 is shown, which is rotatably received within the lock housing 2. In addition to a - not shown - door handle, the locking element 3 can be withdrawn by turning the driver element 4, which represents only an optional feature of the lock 1. Furthermore, the pressure side 6a of the pin member 6 is shown, wherein the pin member 6 within the Stulpes 7 is arranged. When the pin member 6 is depressed, the locking member 3 can be moved to a retracted position, which can be fixed by a change of the selector position.

FIG. 5 shows a further perspective view of the lock 1 with the lock housing 2, the forend 7 and the locking element 3 and the arrangement of the selector element 5. The selector element 5 is designed with at least one notch 5b, wherein the selector element 5 is made of a sheet metal material and the notches 5b within the selector element 5 are formed by a wave structure with wave crests and troughs. The notches 5b are arranged such that they interact with a detent element 11, which has a detent 11a for engagement in the notches 5b of the selector element 5. The locking element 11 is received within the lock mechanism in the lock housing 2 and fixed stationary. The locking lug 11a is arranged at the end of a spring projection, and designed for spring-back, when the selector element 5 switches its position and the locking lug 11a slides along the wave structure of the Selektorelementes 5. Due to the arrangement of the notches 5b for interaction with the detent 11a of the detent element 11, the selector element 5 is designed with selector positions A, B and C, which have a detent effect in their specific positions.

The present invention is not limited to the embodiment described above, which is given by way of example only and within the Schutzumpfanges of the present invention, which is defined by the appended claims, can be changed. Consequently, the invention is also applicable to various embodiments of the lock 1, in particular concerning the execution of the locking element 3, the Carrier element 4 and the interaction between the release agent and the selector element. 5
