Description

The invention relates to an actuating device for a lock with a lock nut and a locking system for mounting on a door leaf with one of such actuating devices.

The documents US 2019/136581 A1 and CN 106 121 379 A show, for example, an actuating device for a lock with a lock nut and a corresponding locking system according to the state of the art.

It is known in practice to use handles designed as doorknobs to operate a door lock. These are arranged on both large surfaces of the door and are connected to one another via a polygonal pin. The handles are arranged on the polygonal pin in a rotationally fixed manner, so that a synchronous adjustment movement occurs when one of the handles is operated. The polygonal pin passes through a lock nut of a mortise lock, which is inserted into a corresponding lock receptacle in the door leaf. The lock nut represents a polygonal receptacle with which the polygonal pin engages in a form-fitting and force-fitting manner. The polygonal pin is usually designed as a square pin, so that the lock nut forms a square receptacle. In particular with doors in sanitary rooms, 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 purpose. For example, a lock can be used that has a bolt that can be operated using a key. A door can be opened in an emergency using the emergency release device.

The invention is based on the object of creating an actuating device for a lock which can be operated safely and easily.

This object is achieved according to the invention by the actuating device having the features of claim 1.

According to the invention, an actuating device for a lock with a lock nut is proposed, comprising a polygonal pin which has a first end region on which a first handle is arranged and a second end region on which a second handle is arranged. The polygonal pin is designed in several parts and comprises a base pin and a slider which comprises an actuating element which is arranged on the first handle and can be actuated manually and which can be adjusted relative to the base pin parallel to the axis of the polygonal pin between an engagement position in which it can be brought into engagement with the lock nut and a blocking position in which the polygonal pin can be rotated relative to the lock nut or in which the polygonal pin can be blocked with respect to rotation about its axis. The slider interacts with an emergency release device on the side of the second handle, the emergency release device comprising a pressure-loaded release means which can be displaced within the second handle for axially displacing the slider into the engagement position.

The slide of the actuating device according to the invention thus creates the positive connection between the polygonal pin and the lock nut. If actuation of the lock nut by means of a handle is to be prevented, the slide can be disengaged from the lock nut. This then corresponds to the locking 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 no torque can be introduced into the lock nut via the polygonal pin, or on the other hand the polygonal pin can be blocked with respect to rotation about its axis so that when one of the handles is actuated no torque can be introduced into the lock nut via the polygonal pin.

The emergency release device makes it possible to open a door in an emergency, even if the slide initially assumes its locked position and it is not possible to operate the lock nut using the second handle. The term "relocatable" can be understood as "slidable". A relocation can be understood as a shift or a displacement. The polygonal pin can be designed as a square pin.

Preferably, the slide is designed as a single piece. Preferably, the slide is designed as a multi-piece, in particular two-piece. Particularly preferably, the slide is designed as a sliding coupling.

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

In a preferred embodiment of the actuating device according to the invention, the slide comprises an engagement section which can be brought into engagement with the lock nut in the engagement position, and a locking section which is tapered relative to the engagement section and which can be rotated relative to the lock nut in the locking position. To reach the locking position, the tapered locking section is thus displaced into the lock nut, whereas in the engagement position in which the lock nut can be actuated by means of one of the handles, the engagement section of the slide is arranged in the lock nut. Alternatively, a means can be provided which is designed to block the polygonal pin from rotating about its axis in the locking position of the slide.

In order to ensure that the slider is moved precisely when adjusting between the engaged position and the locked position, it is advantageous if the base pin has a guide track for the slider. It is of course also conceivable that the guide track is realized by corresponding bends or the like that are formed on the slider itself.

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

In order to be able to move the slide between its end positions, i.e. between the blocking position and the engagement position, according to the invention it comprises an actuating element which is arranged on the first handle and can be operated manually. The first handle is therefore preferably the handle which is arranged on the side of the door which faces in the direction of the room to be secured.

For example, the actuating element is a pin that preferably has a radial orientation with respect to the axis of rotation of the polygonal pin, is guided in an elongated hole in the first handle and passes through a wall of the handle. However, it is also conceivable that the actuating element emerges from the front side of the first handle and can be grasped 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 locked position and it is not possible to operate the lock nut using the second handle.

In a special embodiment of the actuating device according to the invention, the actuating device comprises an adapter piece, wherein the second handle is connected to the adapter piece in a rotationally fixed manner, and the emergency release device comprises a spring means, wherein the spring means is arranged within the second handle, and wherein a first end of the spring means rests on the release means and a second end of the spring means rests on a support surface of the adapter piece. Preferably, the spring means is a spiral spring or a rubber, in particular industrial rubber, such as Fibroflex ^® . Alternatively, a spring-magnet system can be arranged within the second handle as the spring means. Preferably, the spring means is 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, wherein the adapter piece is 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 their axial longitudinal extension. The base pin and the slide are preferably guided at least partially through the spring means in their axial longitudinal extension, preferably through a cavity formed by the spring means. Guiding can also be understood as penetrating.

In a further preferred embodiment, the slide is secured to the base pin in the axial direction. In a still further preferred embodiment, the slide rests against the base pin on the front side in the engaged position.

The slide can comprise a stop for the unlocking means on the front side facing the emergency release device. This makes it possible to move or shift the slide as a result of actuating the unlocking means.

In a particularly preferred embodiment, the unlocking means has a tool attachment, wherein the second handle comprises an opening for receiving a tool in the tool attachment. The unlocking means can be easily displaced or moved using the tool.

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

In a special embodiment, the slider has an upstand, an embossing or a projecting section to limit the insertion depth into the lock nut, which is arranged on one of the sides of the slider opposite the base pin. This makes it easy to determine the insertion or insertion depth of the slider. To limit the insertion or insertion depth, the upstand, the embossing or the projecting section can contact the lock nut when the slider is inserted or inserted into the lock nut.

The invention also relates to a locking system or lock system for mounting on a door leaf, which comprises a lock with a lock nut and an actuating device of the type described above. The polygonal pin of the actuating device passes through the lock nut, wherein the slider can be moved or displaced 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 nut in the engaged position and can be rotated relative to the lock nut in the locked position or can be blocked with respect to rotation about its axis.

Further advantages and advantageous embodiments of the subject matter of the invention can be taken from the description, the drawing and the claims.

Figure 11

a top 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 comprises a mortise lock 14 which is inserted into a recess 16 of the door leaf 10 which is formed on a longitudinal edge of the door leaf 10. The mortise lock 14 has a lock nut 18 which forms a square receptacle 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 surface of the door leaf 10 facing the room to be locked, and a second handle 26, which is attached to the large surface of the door leaf 10 facing away from the room to be locked. The actuating device 22 comprises an adapter piece 61, wherein the second handle 26 is 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, wherein the adapter piece 61 is rotatably mounted in the rosette 25.

The first handle 24 is placed on a first end area of a polygonal pin 28 and is thus connected to it in a rotationally fixed manner. The second handle 26 is placed on a second end area of the polygonal pin 28 and is thus also connected to it in a rotationally fixed manner. The polygonal pin 28 is used to transfer the adjustment forces entered into the handles 24 and 26 to the lock nut 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 nut 18, is made up of several parts and comprises a base pin 32, which is inserted into the Figures 2 to 4 shown in isolation, and a slider 34, which is in the Figures 5 to 8 is shown on its own. The slider 34 rests on the top of the base pin 32 and is guided in guideways 36 of the base pin 32 such that it can be moved parallel to the axis of rotation of the polygonal pin 28 relative to the base pin 32. To guide it in the guideways 36 of the base pin 32, the slider 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.

As in the Figures 5 and 6 As shown, the slider 34 has a raised edge or embossing 33 to limit the insertion depth into the lock nut 18. The raised edge or embossing 33 is arranged on one of the sides of the slider 34 opposite the base pin 32. To limit the insertion depth, the raised edge or embossing 33 contacts the lock nut 18 when the slider 34 is inserted or introduced into the lock nut 18.

How Figure 8 As can be seen, the engagement section 46 has a U-shaped cross-section, the external dimensions and angles of which correspond to the internal dimensions of the lock nut 18. When the engagement section 46 is arranged in the lock nut 18 and one of the handles 24 and 26 is actuated, an actuation takes place the trap 30. The locking section 44 has, as Figure 7 can be seen, an arcuate cross-section, the radius of which is selected such that when arranged in the lock nut 18 and when one of the handles 24 and 26 is actuated, it can rotate freely together with the base pin 32 without the latch 30 being actuated. This position of the slide 34 corresponds to the blocking position, whereas the position of the slide 34 in which the engagement section 46 is arranged in the lock nut 18 corresponds to the engagement position.

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

The actuating pin 48 has a radial orientation and passes through an elongated hole 52 that 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 manually grasped by a user. The elongated hole 52 has a length that corresponds to the adjustment path of the slide 34 between the engagement position in which the latch 30 can be actuated and the locking position in which the polygonal pin 28 rotates freely in the lock nut 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 locking position into the engagement position from the side of the handle 26 in an emergency situation, the actuating device 22 is provided with an emergency release device 54 which can be actuated by means of a tool, e.g. 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 release device 54 comprises a pressurized release means 56 that can be displaced within a cylindrical recess of the second handle 26 for axially displacing the slide 34 into the engaged position.

The emergency release device 54 further comprises a spring means 60, wherein the spring means 60 is arranged within the cylindrical recess of the second handle 26. A first end of the spring means 60 rests on the release means 56. A second end of the spring means 60 rests on 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 guided at least partially through the spring means 60 in the axial longitudinal extension.

The slide 34 has a stop 35 for the release means 56 on the front side facing the emergency release device 54, which in the Figure 6 is shown, and is manufactured in one piece with the slider 34. The unlocking means 56 has a tool attachment 58, wherein the second handle 26 comprises an opening 27 for receiving the tool 70 in the tool attachment 58. The unlocking means 56 is designed to displace the slider 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 operating device 54 operates with reference to the Figures 9 and 10 in the manner described below.

Starting from the locking position of the slide 34, the tool 70 is guided through the opening 27 of the second handle and placed or inserted into the tool attachment 58 of the unlocking means 56. As a result of a pressure force acting (to the left in the leaf plane) 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. The slide 34 is thereby displaced in the direction of the first handle 24. The slide 34 is preferably displaced until the slide 34 rests on the front side against the base pin 32. The engagement section 46 of the slide 34 is thus displaced into the lock nut 18, which in turn actuates the latch 30 when the handle 26 is actuated and the polygonal pin 28 is rotated, and the door leaf 10 can be opened. The slider 34 is then in the engaged position.

After the tool has been removed from the actuating device 22, the pressurized release means 56 returns to its original position (to the right in the plane of the sheet). The slide 34 can then be adjusted again between the engaged position and the locked position by means of the actuating pin 48.

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