LOCKING SYSTEM AND DOOR AND WINDOW WITH LOCKING SYSTEM

Description

[0001] The invention relates to a locking system. Furthermore, the invention relates to a door or window with the locking system.

[0002] It is known in practice to use handles designed as doorknobs to operate a door lock. These handles are arranged on both large surfaces of the door and connected to each other via a polygonal spindle. The handles are mounted on the polygonal spindle in a rotationally fixed manner, so that a synchronous adjustment movement occurs when one of the handles is operated. The polygonal spindle engages the 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 spindle engages in a form-fitting and force-fitting manner.

[0003] The polygonal spindle is usually designed as a square spindle, so that the lock follower forms a square socket. Particularly with doors to sanitary rooms, such as bathrooms or toilets, it may be necessary to secure the room from the inside. Various locking mechanisms are available for this purpose. For example, a lock can be used that has a bolt that can be operated with a key. The emergency release device can be used to open a door in an emergency.

[0004] US Pat. No. 1,768,193 discloses a locking system for a door leaf, comprising a lock with a lock nut and an actuating device. The actuating device comprises a polygonal pin on which a slide is slidably mounted. The slide can be moved between a locking position, in which a locking portion of the slide engages with a recess formed in a lock housing, and a release position, in which the engaging portion of the slide is pulled out of the recess in the lock housing.

[0005] From the publication DE 20 2021 101 322 U1, an actuating device for a lock is known, in which a multi-part polygonal pin is formed, comprising a base pin and a slide. The slide can be displaced on the base pin such that, in a locked position, the polygonal pin can be freely rotated relative to a lock nut. In a released position, the polygonal pin engages with the lock nut, so that the lock can be actuated by actuating a handle.

[0006] The object of the invention is to create a locking system that is safe and easy to operate.

[0007] This object is achieved according to the invention by the locking system having the features of patent claim 1.

[0008] According to the invention, a locking system for mounting on a door leaf is proposed, comprising a lock with a lock nut and an actuating device, wherein the actuating device comprises a polygonal pin which passes through the lock nut and 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 is adjustable relative to the base pin parallel to the axis of the polygonal pin between a release position in which rotation of the polygonal pin about its axis is possible relative to a blocking element arranged on the lock, and a blocking position in which rotation of the polygonal pin about its axis is blocked by means of the blocking element.

[0009] If the lock nut is to be prevented from being operated by a handle, the slider can be engaged with the blocking element. This corresponds to the locked position of the slider, in which the polygonal pin is blocked from rotating around its axis, so that when one of the handles is operated, no torque can be applied to the lock nut via the polygonal pin. In other words, the slider creates a positive connection between the polygonal pin and the blocking element.

[0010] If operation of the lock nut using a handle is to be permitted or achieved, the slide can be disengaged from the blocking element. This then corresponds to the release position of the slide, in which the polygonal pin can be rotated about its axis, so that when one of the handles is operated, a torque can be applied to the lock nut via the polygonal pin. In other words, there is no longer a positive connection between the polygonal pin and the blocking element. However, a positive connection is or can be established between the polygonal pin and the lock nut.

[0011] A locking system can be understood as a lock system. "Displaceable" can be understood as "slidable." Displacement can be understood as a shift or a movement. The polygonal pin can be designed as a square pin or a push-button pin.

[0012] The slide is preferably formed as a single piece. The slide is preferably formed as a multi-piece, particularly a two-piece, slide. The slide is particularly preferably formed as a sliding coupling.

[0013] In a preferred embodiment of the locking system according to the invention, the slider comprises a blocking section that engages with the blocking element in the locked position, and a release section that is tapered relative to the blocking section and that is rotatable or twisted relative to the blocking element in the release position. "Engagement" can be understood as a positive fit. The release section can have a rounded or arcuate cross-section.

[0014] To reach the locking position, the blocking section is moved into the blocking element, whereas in the release position, in which the lock nut can be actuated by means of one of the handles, the release section of the slider is moved into the blocking element.

[0015] In the locking system according to the invention, the polygonal pin penetrates the blocking element. The blocking element has an opening to accommodate the polygonal pin. In other words, the polygonal pin is guided through an opening in the blocking element. The opening in the blocking element has a cross-section that corresponds to the cross-section of the polygonal pin. This allows for a positive fit and / or displacement of the slider.

[0016] Fasteners such as screws or rivets can be used to attach the blocking element to the lock. Preferably, the blocking element is attached or arranged to the lock in a force-fitting manner. In other words, the blocking element is connected to the lock in a rotationally fixed manner. According to the invention, the blocking element is a sheet metal. Preferably, the blocking element is made of metal or metal and plastic.

[0017] In a particular embodiment of the locking system according to the invention, the slider comprises an engagement portion that engages or can be brought into engagement with the lock nut. Preferably, the engagement portion is arranged displaceably in the lock nut, independent of the release or locking position.

[0018] To ensure precise positioning of the slider when adjusting between the release and lock positions, it is advantageous for the base pin to have a guideway for the slider. It is also conceivable, of course, that the guideway be realized by corresponding bevels or the like formed on the slider itself.

[0019] In a special embodiment of the locking system according to the invention, the base pin has a tapered portion, in the area of ​​which the engagement section, the release section, and the blocking section of the slider are arranged. Thus, the effective range of the slider is always located within a defined area of ​​the base pin.

[0020] To enable the slide to be moved, it advantageously comprises an actuating element arranged on the first handle and operable manually. The first handle is thus preferably the handle arranged on the side of the door facing the room to be secured.

[0021] For example, the actuating element is a pin, which is preferably radially aligned with respect to the rotational axis of the polygonal pin, is guided in a slotted hole in the first handle, and extends through a wall of the handle. However, it is also conceivable for the actuating element to protrude from the front side of the first handle and be manually graspable by a user.

[0022] In the locking system according to the invention, the slider 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 slider initially assumes its locked position and the lock follower cannot be operated using the second handle.

[0023] In a further preferred embodiment of the locking system according to the invention, the emergency release device comprises a pressurized release means which can be displaced within the second handle for axially displacing the slider into the release position.

[0024] The slider can cooperate with an emergency release device on the side of the second handle, wherein the emergency release device comprises a pressurized release means that can be displaced within the second handle for axially displacing the slider into the release position.

[0025] The unlocking means is preferably formed as a single piece. The unlocking means is preferably formed as a multi-piece, particularly a two-piece, structure. For thicker doors, a multi-piece design may be useful to reduce the displacement path. The unlocking means is particularly preferably arranged within a cylindrical recess in the second handle.

[0026] In a special embodiment of the locking system 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 bears against the unlocking means and a second end of the spring means bears against 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®. Further 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.

[0027] In a further embodiment of the locking system 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.

[0028] In a preferred embodiment of the locking system according to the invention, the base pin and the slider are guided at least partially through the support surface in their axial longitudinal extension. Preferably, the base pin and the slider are guided at least partially through the spring means, preferably through a cavity formed by the spring means, in their axial longitudinal extension. Guiding can also be understood as penetration.

[0029] In a further preferred embodiment of the locking system according to the invention, the slider is secured to the base pin in the axial direction. In yet another preferred embodiment, the slider rests against the base pin at its end in the release position.

[0030] The slider may include a stop for the release mechanism on the end face facing the emergency release device. This makes it possible to displace or slide the slider upon actuation of the release mechanism.

[0031] In a particularly preferred embodiment of the locking system according to the invention, the unlocking means comprises a tool attachment or an actuating guide, wherein the second handle comprises an opening for receiving a tool in the tool attachment or in the actuating guide. The unlocking means can be easily displaced or shifted using the tool.

[0032] In a particularly preferred embodiment of the locking system according to the invention, the unlocking means is configured to move the slider into the release position. For this purpose, the unlocking means can preferably strike or engage the stop of the slider, thereby moving the slider into the release position.

[0033] In a special embodiment of the locking system according to the invention, the slider has an upstand, an embossing, or a projecting section to limit the insertion depth into the lock nut. This upstand, an embossing, or a projecting section 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.

[0034] The invention also relates to a door or window with a locking system.

[0035] Further advantages and advantageous embodiments of the subject matter of the invention can be found in the description, the drawings and the patent claims.

[0036] An embodiment of a locking system according to the invention is shown schematically in the drawing and is explained in more detail in the following description. It shows: Figure 1 shows a perspective view of a door leaf with a lock, an actuating device for the lock and an emergency release device in an exploded view; Figure 2 shows a plan view of a base pin of a polygonal pin of the actuating device; Figure 3 shows a longitudinal section through the base pin along the line II in Figure 2 ; Figure 4 a section through the base pin along the line II-II in Figure 3; Figure 5 a top view of a slider of the polygonal pin; Figure 6 a longitudinal section through the slider along the line III-III in Figure 5 ; Figure 7 a section through the slide along the line IV-IV in Figure 6 ; Figure 8 a section through the slide along the line VV in Figure 6 ; Figure 9 a section through the slide along the line VI-VI in Figure 6 ; Figure 10 a perspective view of the polygonal pin from Figure 1 ; Figure 11 shows a section through the door leaf with the lock, the actuating device for the lock and an emergency release device in the assembled state; Figure 12 shows a further section through the door leaf with the lock, the actuating device for the lock and an emergency release device in the assembled state; Figure 13 shows a perspective view of the lock before mounting a blocking element; and Figure 14 shows a perspective view of the lock after mounting the blocking element.

[0037] In Figure 1 A door leaf 10 is shown, which is provided with a locking system 12 shown in an exploded view. The locking 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 formed on the two large surfaces of the door leaf 10. Furthermore, the locking system 12 comprises a blocking element 17, which forms a square receptacle. The blocking element 17 can be attached to the mortise lock 14 by means of fastening means (not shown).

[0038] The locking 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 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 includes 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.

[0039] The first handle 24 is attached to a first end portion 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 portion of the polygonal pin 28 and is thus also connected to it in a rotationally fixed manner. The polygonal pin 28 serves to transmit the adjustment forces applied to 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.

[0040] The polygonal pin 28, which passes through the lock nut 18 and the blocking element 17, is designed in 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 9is shown in isolation. The slider 34 rests on the upper side of the base pin 32 and is guided in guideways 36 of the base pin 32 such that it can be displaced relative to the base pin 32 parallel to the axis of rotation of the polygonal pin 28. For guidance 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 blocking section 43, a release section 44, and an engagement section 46.

[0041] As in the Figures 5 and 6As 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 side of the slider 34 opposite the base pin 32. To limit the insertion depth, the raised edge or embossing 33 contacts the blocking element 17 when the slider 34 is displaced to the right in the plane of the sheet.

[0042] How Figure 7 As 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 engaged 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.

[0043] How Figure 8As can be seen, the release section 44 has an arcuate cross-section, the radius of which is selected such that, when arranged in the opening 19 of the blocking element 17 and when one of the handles 24 and 26 is actuated, it can rotate freely together with the base pin 32, so that the latch 30 is actuated.

[0044] How Figure 9 As can be seen, the engagement portion 46 has a U-shaped cross-section, the outer dimensions and angle of which correspond to the inner dimensions of the lock nut 18. The engagement portion 46 is arranged in the lock nut 18. Actuation of the latch 30 is only possible when the release portion 44 is located in the opening 19 of the blocking element 17. Conversely, the latch 30 is not actuated when the blocking portion 43 is located in the opening 19 of the blocking element 17.

[0045] To adjust the slide 34, an actuating element in the form of an actuating pin 48 is attached to the guide section 38 in one 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 cover 51 is mounted on the actuating pin 48.

[0046] The actuating pin 48 has a radial orientation and extends through an elongated hole 52 formed on a shaft portion of the handle 24 and extending parallel to the axis of the polygonal pin 28. Thus, the actuating pin 48 is manually graspable 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 locked position, in which the polygonal pin 28 cannot rotate in the lock nut 18 upon actuation of one of the handles 24 and 26, thus preventing the latch 30 from being actuated.

[0047] In order to be able to move the slide 34 from the locking position to the release 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 (not shown), for example a screwdriver or the like.

[0048] 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 release position.

[0049] 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 against 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 by the support surface 62 in their axial longitudinal extension. Furthermore, the base pin 32 and the slide 34 are guided at least partially by the spring means 60 in their axial longitudinal extension.

[0050] The slide 34 has on the end face facing the emergency release device 54 a stop 35 for the release means 56, 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 a tool in the tool attachment 58. The unlocking means 56 is configured to displace the slider 34 into the release position.

[0051] 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 actuation device 54 operates with reference to the Figures 9 and 10 in the manner described below.

[0052] Starting from the locked position of the slide 34, the tool 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 compressive force acting on the tool (to the left in the leaf plane) in the axial direction of the tool, the unlocking means 56 is displaced towards the stop 35 of the slide 34 against the spring force of the spring means 60. In doing so, the slide 34 is displaced towards the first handle 24. Preferably, the slide 34 is displaced until the end face of the slide 34 rests against the base pin 32. This displaces the release section 44 of the slide 34 into the blocking element 17, whereby in turn, upon actuation of the handle 26 and rotation of the polygonal pin 28, the latch 30 is actuated and the door leaf 10 can be opened. The slide 34 is then in the release position.

[0053] After removing the tool from the actuating device 22, the pressurized release mechanism 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 release position and the locking position using the actuating pin 48.

[0054] The first handle 24 may have a first marking and a second marking (not shown) arranged on either side of the elongated hole 52. When the actuating pin 48 is inserted, either the first marking or the second marking is visible. The markings serve to indicate whether a release position or a lock position is present.
