Description

The invention relates to an actuating device with an emergency unlocking device for a lock with a lock follower, a further actuating device for a lock with a lock follower and a locking system for mounting on a door leaf with one of such actuating devices.

It is known from practice to use handles designed as door handles to actuate a lock of a door, which are arranged on both large surfaces of the door and are connected to one another via a polygonal pin. The handles are arranged non-rotatably on the polygonal pin, so that a synchronous adjustment movement occurs when one of the handles is actuated. The polygonal pin passes through a lock follower of a mortise lock, which is inserted into a corresponding lock receptacle of the door leaf. The lock follower represents a polygonal receptacle with which the polygonal pin is positively and non-positively engaged. The polygonal pin is usually designed as a square pin, so that the lock follower forms a square receptacle. In the case of doors to sanitary rooms in particular, such as bathrooms or toilets, it may be necessary to secure the room in question from the inside. Various locking mechanisms are known for this. For example, a lock can be used that has a bolt that can be actuated by means of a key. A door can be opened in an emergency using the emergency release device.

The object of the invention is to provide an actuating device for a lock that can be actuated safely and easily.

According to the invention, this object is achieved by the actuating device having the features of claim 1 .

According to the invention, an actuating device for a lock with a lock follower is therefore proposed, comprising a polygonal pin which has a first end area on which a first handle is arranged and a second end area on which a second handle is arranged. The polygonal pin is designed in several parts and comprises a base pin and a slide which can be adjusted relative to the base pin parallel to the axis of the polygonal pin between an engaged position in which it can be brought into engagement with the lock follower and a locked position in which the polygonal pin can be moved relative to the lock follower is rotatable or in which the polygonal pin can be blocked with respect to rotation about its axis. On the side of the second handle, the slide interacts with an emergency release device, the emergency release device comprising a release means that is subjected to pressure and can be displaced within the second handle, for the axial displacement of the slide into the engaged position.

The slide of the actuating device according to the invention thus produces the form fit between the polygonal pin and the lock follower. If actuation of the lock follower is to be prevented by means of a handle, the slide can be disengaged with respect to the lock follower. This then corresponds to the blocking position of the slide, in which on the one hand the polygonal pin can be rotated relative to the lock nut, so that when one of the handles is actuated via the polygonal pin, no torque can be applied to the lock nut or, on the other hand, the polygonal pin can be blocked with regard to rotation about its axis , so that when one of the handles is actuated via the polygonal pin, no torque can be entered into the lock follower.

The emergency unlocking device makes it possible for a door to be opened in an emergency, even if the slide initially assumes its locked position and it is not possible to actuate the lock follower using the second handle.

Relocatable can be understood to mean displaceable. A relocation can be understood to mean a displacement or a displacement. The polygonal pin can be designed as a square pin.

The slide is preferably designed in one piece. The slide is preferably designed in several parts, in particular in two parts. The slider is particularly preferably designed as a sliding clutch.

The unlocking means is preferably designed in one piece. The unlocking means is preferably designed in several parts, in particular in two parts. In the case of large doors, a multi-part construction can be useful in order to reduce the displacement path. The unlocking means is particularly preferably arranged within a cylindrical recess of the second handle.

In a preferred embodiment of the actuating device according to the invention, the slide comprises an engagement section which can be engaged with the lock follower in the engaged position, and a locking section which is tapered relative to the engagement section and which can be rotated relative to the lock follower in the locked position. To reach the blocking position, the tapered blocking section is shifted into the lock follower, whereas in the engaged position, in which the lock follower can be actuated by one of the handles, the engagement section of the slide is arranged in the lock follower. Alternatively, a means can be provided which is set up to block the polygonal pin from rotating about its axis when the slide is in the blocking position.

In order to ensure a precisely positioned displacement of the slider when adjusting between the engaged position and the locked position, it is advantageous if the base pin has a guideway for the slider. It is also conceivable, of course, for the guideway to be realized by appropriate folds or the like, which are formed on the slide itself.

In a special embodiment of the actuating device according to the invention, the base pin has a taper in the region of which the engagement section and the locking section of the slide are arranged. The effective area of the slider is thus always arranged in a defined area of the base pin.

In order to be able to move the slider between its end positions, ie between the blocking position and the engaged position, it expediently comprises an actuating element which is arranged on the first handle and can be actuated manually. The first handle is therefore preferably the handle that is arranged on the side of the door that points in the direction of the room to be secured.

For example, the actuating element is a pin, which preferably has a radial alignment with respect to the axis of rotation of the polygonal pin, is guided in a slot in the first handle and reaches through a wall of the handle. However, it is also conceivable that the actuating element emerges from the first handle at the end face and can be gripped manually by a user.

In a preferred embodiment of the actuating device according to the invention, the slide on the side of the second handle interacts with the emergency release device. This ensures that a door can be opened in an emergency, even if the slide initially assumes its blocked position and it is not possible to actuate the lock follower using the second handle.

In a special embodiment of the actuating device according to the invention, the actuating device comprises an adapter piece, with the second handle being connected to the adapter piece in a rotationally fixed manner, and the emergency release device comprising a spring means, with the spring means being arranged inside the second handle, and with a first end of the spring means rests against the unlocking means and a second end of the spring means rests against a support surface of the adapter piece. The spring means is preferably a spiral spring or rubber, in particular industrial rubber such as ^Fibroflex® . As a further alternative, a spring-magnet system can be arranged within the second handle as the spring means. The spring means is preferably arranged within the cylindrical recess of the second handle.

In a further embodiment of the actuating device according to the invention, the actuating device comprises a rosette, with the adapter piece being rotatably mounted in the rosette. In other words, the second handle is rotatably connected to the rosette.

In a preferred embodiment, the base pin and the slide are guided at least partially through the support surface in the axial longitudinal extension. Preferably, the base pin and the slide are at least partially guided in the axial longitudinal extent by the spring means, preferably through a hollow space formed by the spring means. Leading can also be understood as penetrating.

In a further preferred embodiment, the slider is secured to the base pin in the axial direction. In yet another preferred embodiment, the slide rests on the front side of the base pin in the engaged position.

The slide can include a stop for the unlocking means on the end face facing the emergency unlocking device. This makes it possible to shift or move the slide as a result of actuation of the unlocking means.

In a particularly preferred embodiment, the unlocking means has a tool attachment, with the second handle comprising an opening for receiving a tool in the tool attachment. The unlocking means can be relocated or moved in a simple manner by means of the tool.

In a particularly preferred embodiment, the unlocking means is set up to move the slide into the engaged position. For this purpose, the unlocking means can hit the stop of the slide in order to move the slide into the engaged position.

In a special embodiment, the slide has an upstand, an embossing or a projecting section to limit the depth of insertion into the lock follower, which is arranged on the side of the slide opposite the base pin. As a result, it is possible in a simple manner to determine the insertion or insertion depth of the slide. To limit the depth of insertion or insertion, the upstand, the embossing or the protruding section can contact the lock follower when the slide is pushed in or inserted into the lock follower.

The invention also relates to an actuating device for a lock with a lock follower, comprising a polygonal pin which has a first end area on which a first handle is arranged and a second end area on which a second handle is arranged. The polygonal pin is designed in several parts and comprises a base pin and a slide which can be adjusted relative to the base pin parallel to the axis of the polygonal pin between an engaged position in which it can be brought into engagement with the lock follower and a locked position in which the polygonal pin can be moved relative to the lock follower is rotatable or in which the polygonal pin can be blocked with respect to rotation about its axis. To limit the depth of insertion into the lock follower, the slide has an upstand, an embossing or a projecting section, which is arranged on the side of the slide opposite the base pin.

The subject matter of the invention is also a locking system or lock system for mounting on a door leaf, which includes a lock with a lock follower and an actuating device of the type described above. The polygonal pin of the actuating device passes through the lock follower, with the slide being displaceable or displaceable relative to the base pin parallel to the axis of the polygonal pin in such a way that it is in engagement with the lock follower in engagement and can be rotated relative to the lock follower in the locked position or with respect to a rotation can be locked around its axis.

Further advantages and advantageous configurations of the subject matter of the invention can be found in the description, the drawing and the claims.

figure 11

a plan view of a first handle of the lock system.

In figure 1 a door leaf 10 is shown, which is provided with a lock system 12 shown in an exploded view. The lock system 12 includes a mortise lock 14 which is inserted into a recess 16 in the door panel 10 which is formed on a longitudinal edge of the door panel 10 . The mortise lock 14 has a lock follower 18 which forms a square socket and is accessible via recesses 20 which are formed on the two large surfaces of the door leaf 10 .

The lock system 12 comprises an actuating device 22, which has a first handle 24, which is attached to the large area of the door leaf 10 facing the space to be locked, and a second handle 26, which is attached to the large area of the door leaf 10 facing away from the room to be locked . The operating device 22 comprises an adapter piece 61, the second handle 26 being connected to the adapter piece 61 in a rotationally fixed manner. Furthermore, a rosette 25 is arranged between the door leaf 10 and the second handle 26 , the adapter piece 61 being rotatably mounted in the rosette 25 .

The first handle 24 is slipped onto a first end region of a polygonal pin 28 and is thus connected to it in a rotationally fixed manner. The second handle 26 is attached to a second end area of the polygonal pin 28 and is therefore likewise connected to it in a rotationally fixed manner. The polygonal pin 28 is used to transfer the adjustment forces introduced into the handles 24 and 26 to the lock follower 18 so that actuation of the handles 24 and 26 leads to actuation of a latch 30 of the mortise lock 14 .

The polygonal pin 28, which penetrates the lock follower 18, is designed in several parts and includes a base pin 32, which is in the Figures 2 to 4 is shown on its own, and a slide 34, which in the Figures 5 to 8 is shown on its own. The slide 34 rests on the upper side of the base pin 32 and is guided in guideways 36 of the base pin 32 in such a way that it can be displaced parallel to the axis of rotation of the polygonal pin 28 relative to the base pin 32 . For guidance in the guide tracks 36 of the base pin 32, the slide 34 has two strip-like guide sections 38 and 40, between which an active section 42 is arranged. The active section 42 comprises a locking section 44 and an engagement section 46.

Like in the Figures 5 and 6 shown, the slide 34 has an upstand or embossing 33 to limit the depth of insertion into the lock follower 18 . The raised edge or embossing 33 is arranged on the side of the slide 34 opposite the base pin 32 . To limit the insertion depth, the raised edge or embossing 33 contacts the lock follower 18 when the slide 34 is pushed in or inserted into the lock follower 18.

As figure 8 it can be seen that the engagement section 46 has a U-shaped cross section, the outer dimensions and angle of which correspond to the inner dimensions of the lock follower 18 . When the engagement section 46 is arranged in the lock follower 18 and one of the handles 24 and 26 is actuated, an actuation takes place the case 30. The locking portion 44 has, like figure 7 can be seen, an arcuate cross section, the radius of which is selected such that it can rotate freely together with the base pin 32 when it is arranged in the lock follower 18 and when one of the handles 24 and 26 is actuated, without the latch being actuated 30 is coming. This position of the slide 34 corresponds to the locked position, whereas the position of the slide 34 in which the engagement section 46 is arranged in the lock follower 18 corresponds to the engaged position.

In order to be able to adjust the slider 34 between the engaged position and the locked position, an actuating pin 48 is fastened to the guide section 38 in an end area. The actuating pin 48 can be inserted into a bore (not shown) of the slide 34 by means of a fastening means 50 . A panel 51 is placed on the actuating pin 48 .

The actuating pin 48 has a radial orientation and passes through a slot 52 which is formed on a shaft section of the handle 24 and extends parallel to the axis of the polygonal pin 28 . The actuating pin 48 can thus be gripped manually by a user. The elongated hole 52 has a length that corresponds to the adjustment path of the slide 34 between the engaged position, in which the latch 30 can be actuated, and the blocking position, in which the polygonal pin 28 rotates idly in the lock follower 18 when one of the handles 24 and 26 is actuated and the latch 30 is not actuated.

In order to be able to move the slide 34 from the locked position into the engaged position from the side of the handle 26 in an emergency, the actuating device 22 is provided with an emergency release device 54 which can be actuated using a tool, for example a screwdriver or the like.

The slide 34 interacts with the emergency release device 54 on the side of the second handle 26 . The emergency unlocking device 54 comprises an unlocking means 56 which is pressurized and can be displaced within a cylindrical recess in the second handle 26 for the axial displacement of the slide 34 into the engaged position.

Furthermore, the emergency release device 54 includes a spring means 60, the spring means 60 being arranged within the cylindrical recess of the second handle 26. A first end of the spring means 60 rests on the unlocking means 56 . A second end of the spring means 60 rests against a support surface 62 of the adapter piece 61 . The base pin 32 and the slide 34 are guided at least partially through the support surface 62 in the axial longitudinal extension. Furthermore, the base pin 32 and the slide 34 are at least partially guided by the spring means 60 in the axial longitudinal extension.

The slide 34 has on the emergency release device 54 facing end face a stop 35 for the unlocking means 56, which in the figure 6 is shown, and is made in one piece with the slide 34. The unlocking means 56 has a tool attachment 58 , the second handle 26 including an opening 27 for receiving the tool 70 in the tool attachment 58 . The unlocking means 56 is set up to move the slide 34 into the engaged position.

In the figure 9 the emergency release device 54 is shown in a non-activated state. In the figure 10 the emergency release device 54 has been activated. The emergency actuator 54 operates with reference to FIG figures 9 and 10 in the manner described below.

Starting from the locked position of the slide 34, the tool 70 is guided through the opening 27 of the second handle and attached or introduced into the tool attachment 58 of the unlocking means 56. As a result of a compressive force (to the left in the plane of the drawing) on the tool 70 in the axial direction of the tool 70 , the unlocking means 56 is displaced in the direction of the stop 35 of the slide 34 against the spring force of the spring means 60 . In the process, the slide 34 is displaced in the direction of the first handle 24 . The slide 34 is preferably displaced until the slide 34 rests against the base pin 32 at the front. The engagement section 46 of the slide 34 is thus displaced into the lock follower 18, which in turn actuates the latch 30 and the door leaf 10 can be opened when the handle 26 is actuated and the polygonal pin 28 is rotated. The slider 34 is then in the engaged position.

After removing the tool from the actuating device 22, the pressurized unlocking means 56 moves back into its original position (to the right in the plane of the drawing). The slider 34 can thus be adjusted again between the engaged position and the locked position by means of the actuating pin 48 .

The first handle 24 as shown in figure 11 is shown has a first marking 64 and a second marking 66 which are arranged on both sides of the slot 52 . When the actuating pin 48 is inserted, either the first marking 64 or the second marking 66 is visible. The markings are used to indicate whether there is either an engaged position or a locked position.
