Description

The invention relates to a locking system. Furthermore, the invention relates to a door or a window with the locking system.

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 a locking system that can be operated safely and easily.

According to the invention, this object is achieved by the locking system having the features of patent claim 1 .

According to the invention, a locking system for mounting on a door leaf is therefore proposed, comprising a lock with a lock follower and an actuating device, the actuating device comprising a polygonal pin which reaches through the lock follower and which has a first end region on which a first handle is arranged and a second Has an end area on which a second handle is arranged Lock arranged blocking element is made possible, and a blocking position is adjustable in which rotation of the polygonal pin is blocked about its axis by means of the blocking element.

If the lock follower is to be prevented from being actuated by means of a handle, the slide can be brought into engagement with the blocking element. This then corresponds to the blocking position of the slide, in which the polygonal pin is blocked from rotating about its axis, so that when one of the handles is actuated via the polygonal pin, no torque can be introduced into the lock follower. In other words, the slide creates a form fit between the polygonal pin and the blocking element.

If an actuation of the lock follower is to be permitted or achieved by means of a handle, the slide can be disengaged with respect to the blocking element. This then corresponds to the release position of the slide, in which the polygonal pin can be rotated about its axis with respect to rotation, so that when one of the handles is actuated via the polygonal pin, a torque can be entered into the lock follower. In other words, there is no longer a form fit between the polygonal pin and the blocking element. A form fit will or can be produced between the polygonal pin and the lock follower.

A locking system can be understood to mean a lock system. 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 or pusher 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.

In a preferred embodiment of the locking system according to the invention, the slide comprises a blocking section which is in engagement with the blocking element in the blocking position, and a release section which is tapered relative to the blocking section and which can be twisted or twisted relative to the blocking element in the release position. Being engaged can be understood as being in a form fit. The release portion may have a rounded or arcuate cross section.

To reach the blocking position, the blocking section is shifted into the blocking element, whereas in the release position, in which the lock follower can be actuated by one of the handles, the release section of the slide is shifted into the blocking element.

In a special embodiment of the locking system according to the invention, the polygonal pin passes through the blocking element. The blocking element preferably has an opening for receiving the polygonal pin. In other words, the polygonal pin is guided through an opening in the blocking element. The opening of the blocking element preferably has a cross section which corresponds to the cross section of the polygonal pin. As a result, a form fit and/or a displacement of the slide are possible.

Fasteners, such as screws or rivets, can be used to fasten the blocking element to the lock. The blocking element is preferably fastened or arranged in a non-positive manner on the lock. In other words, the blocking element is non-rotatably connected to the lock. The blocking element can be a metal sheet. The blocking element is preferably made of metal and/or plastic.

In a special embodiment of the locking system according to the invention, the slider comprises an engagement section which is in engagement with the lock follower or with her can be brought into engagement. The engagement section is preferably arranged in the lock follower so that it can be displaced independently of the release or the blocking position.

In order to ensure a precisely positioned displacement of the slider when adjusting between the release position and the blocked 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 locking system according to the invention, the base pin has a taper in the region of which the engagement section, the release section and the blocking section of the slider 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 slide, 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 locking system 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 further preferred embodiment of the locking system according to the invention, the emergency unlocking device comprises an unlocking means, which is subjected to pressure and can be displaced within the second handle, for the axial displacement of the slide into the release position.

The slide can interact with an emergency release device on the side of the second handle, the emergency release device comprising an unlocking means that is pressurized and can be displaced within the second handle for the axial displacement of the slide into the release position.

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 special embodiment of the locking system according to the invention, the actuating device comprises an adapter piece, with the second handle being non-rotatably connected to the adapter piece, 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 locking system 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 of the locking system according to the invention, 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 of the locking system according to the invention, the slide 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 release 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 of the locking system according to the invention, the unlocking means comprises a tool attachment or an operating guide, the second handle comprising an opening for receiving a tool in the tool attachment or in the operating guide. The unlocking means can be relocated or moved in a simple manner by means of the tool.

In a particularly preferred embodiment of the locking system according to the invention, the unlocking means is set up to move the slide into the release position. For this purpose, the unlocking means can preferably strike or act on the stop of the slide in order to move the slide into the release position.

In a special embodiment of the locking system according to the invention, 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 subject of the invention is also a door or window with a locking system.

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

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 . Furthermore, the lock system 12 includes a blocking element 17, which forms a square receptacle. The blocking element 17 can be attached to the mortise lock 14 by means of attachment means (not shown).

The lock system 12 also includes an actuating device 22, which has a first handle 24, which is attached to the large surface of the door leaf 10 facing the space to be locked, and a second handle 26, which is attached to the large surface of the door leaf 10 facing away from the space to be locked is. The actuating device 22 includes 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 attached to a first end region of the polygonal pin 28, which is designed as a square, 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 passes through the lock follower 18 and the blocking element 17, 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 9 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 blocking section 43, a release 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 depth of insertion, the raised edge or embossing 33 contacts the blocking element 17 when the slide 34 is displaced to the right in the plane of the page.

As figure 7 can be seen, the blocking section 43 has a U-shaped cross section, the outer dimensions and angle of which correspond to the inner dimensions of the opening 19 of the blocking element 17 . The blocking section 43 is in engagement with the blocking element 17. When the blocking section 43 is located in the blocking element 17 and one of the handles 24 and 26 is actuated, the latch 30 is not actuated.

As figure 8 As can be seen, the release section 44 has an arcuate cross section, the radius of which is selected in such a way that it can rotate freely together with the base pin 32 when it is arranged in the opening 19 of the blocking element 17 and when one of the handles 24 and 26 is actuated, so that the latch 30 is actuated.

As figure 9 can be seen, the engaging portion 46 has a U-shaped cross section, the outer dimensions and angle with the inner dimensions of Lock follower 18 correspond. The engagement section 46 is arranged in the lock follower 18 . Actuation of the latch 30 is only possible when the release section 44 is in the opening 19 of the blocking element 17 . Conversely, the latch 30 is not actuated when the blocking section 43 is in the opening 19 of the blocking element 17 .

In order to be able to adjust the slide 34, an actuating element in the form of an actuating pin s48 is fastened to the guide section 38 in an end region. 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 release position, in which the latch 30 can be actuated, and the blocked position, in which the polygonal pin 28 cannot be in the lock follower 18 when one of the handles 24 and 26 is actuated can rotate and thus no actuation of the case 30 takes place.

In order to be able to bring the slide 34 from the locked position into the release 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 (not shown), 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 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 release position.

Furthermore, the emergency release device 54 includes 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 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 a tool in the tool attachment 58 . The unlocking means 56 is set up to move the slide 34 into the release position.

In the figure 11 the emergency release device 54 is shown in a non-activated state. In the figure 12 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 is passed 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 in the axial direction of the tool, 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. Thus, the release portion 44 of the slide 34 is pushed into the blocking element 17, whereby in turn, when the handle 26 is actuated and the polygonal pin 28 is rotated, the latch 30 is actuated and the door leaf 10 can be opened. The slider 34 is then in the release 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 slide 34 can thus be adjusted again between the release position and the locked position by means of the actuating pin 48 .

The first handle 24 can have a first marking and a second marking (not shown), which are arranged on both sides of the elongated hole 52 . When the actuating pin 48 is inserted, either the first marking or the second marking is visible. The markings are used to indicate whether there is either a release position or a locked position.
