LOCKING DEVICE WITH A DAY LOCKING DEVICE AND DOOR OR WINDOW ARRANGEMENT WITH SUCH A LOCKING DEVICE

Description

[0001] The invention relates to a locking device having the features of the preamble of claim 1 and a door or window arrangement having the features of the preamble of claim 12.

[0002] Day release devices of the type mentioned above are known from the prior art and are frequently installed in a door or window in conjunction with a locking device. A door or window typically has a frame that defines an opening and a sash that is pivotally mounted on the frame, the sash closing the opening in a closed position (door or window closed) and opening the opening in an open position (door or window open).

[0003] A day release device, when activated, prevents automatic or self-locking by the locking mechanism when the door or window is closed. This prevents the closed door or window from being opened by applying force to the sash, particularly by pushing on it in the opening direction. When the day release device is deactivated, the door or window locks automatically upon closing using the locking mechanism's automatic latches, and opening by applying force to the sash in the opening direction is not possible.

[0004] EP 3 051 045 A1 discloses a locking device according to the preamble of claim 1, comprising a switching device for activating or deactivating a tag function in a lock system with a push rod and at least one locking element movable by means of the push rod. The switching device has a handle and a locking slide with a projection. The handle activates or deactivates the tag function, whereby, when the tag function is activated, the projection of the locking slide is pressed against the push rod by a spring. When the movable locking element is moved into an unlocked position by means of the push rod, the projection engages in a recess in the push rod and thereby blocks the push rod, so that the locking element remains in the unlocked position.

[0005] EP 3 112 567 A1 shows a device that activates or deactivates a tag function on a lock. The lock includes locking elements that can be actuated by means of a push rod. When the lock is in the unlocked position, the tag function can be activated or deactivated via a rotary switch on the device. The rotary switch has a control projection which, when the rotary switch is actuated, interacts with a recess in the push rod to hold the lock in the unlocked position when the tag function is activated.

[0006] DE 195 06 430 A1 discloses a catch for a tilt-and-turn door. CH 639 169 A5 discloses an edge drive for a window or door.

[0007] The object of the present invention is to provide a locking device with a day release mechanism that has improved properties, in particular is reliable, and can be retrofitted to a door or window with a locking device. A further object of the present invention is to provide a door or window assembly that includes such a day release mechanism.

[0008] The invention solves these problems through the features of claim 1 and claim 12. Advantageous embodiments and further developments of the invention result from the dependent claims.

[0009] The locking device is designed and / or intended for a door or window. The locking device comprises a main lock having a bolt and / or a latch, in particular a conventional latch or a (first) automatic latch, at least one secondary lock having a (possibly second) automatic latch and possibly a conventional latch, and a drive rod.

[0010] The secondary lock is coupled to the main lock by means of the drive rod. The locking mechanism also includes a day latch release. The day latch release has a detent module designed and configured to lock all automatic latches of the locking mechanism in an unlocked position when activated and to release all automatic latches when deactivated. The day latch release also has a holding module designed and configured to hold a sash of the door or window closed when the detent module is activated. When activated and with the door or window closed and equipped with the day latch release, the detent module is held by the holding module, and in particular, is releasably held in this position.In the deactivated state, the locking module is not held by the holding module.

[0011] The locking device can have one, two, or three automatic latches. The locking device comprises a main lock with a latch, in particular a conventional latch or a (first) automatic latch, and / or a bolt, as well as at least one secondary lock with a (second) automatic latch and, optionally, a conventional latch.

[0012] The holding module is designed to keep the door or window sash in a closed position and to release the held sash when a force applied to the sash exceeds a threshold force (limit opening force). When the locking module is held by the holding module, opening the door or window equipped with the day latch requires a force on the sash exceeding the limit opening force. The limit opening force can be the minimum force required for the holding module to release a held locking module. The limit opening force can be in the range of 10 to 50 Newtons.

[0013] Advantageously, due to the limiting opening force required to open the door or window, a greater force is required on the sash when the locking module is held by the retaining module than when the locking module is not held by the retaining module. In particular, holding the locking module in place by the retaining module prevents the closed door or window from opening unintentionally when the automatic latches are in the unlocked position and the locking module is in the activated state. For example, an unintentional force less than the limiting opening force can act on the sash of the closed door or window without actually opening it. Such an unintentional force could be caused, for instance, by a light gust of wind or an unintentional vibration. This makes the day release device particularly reliable.

[0014] The automatic latches can assume either the unlocked or a locked position. All automatic latches of the locking device can be coupled to each other by means of a connecting rod, so that all automatic latches are either in the unlocked or the locked position.

[0015] In the unlocked position, the closed door or window, equipped with the locking device, can be opened by applying force to the sash, particularly by pushing on it from a user, in the opening direction. In the locked position, the closed door or window, equipped with the locking device, cannot be opened by applying force to the sash in the opening direction. In this case, for example, opening the door or window may require, in addition to applying force to the sash, operating a door handle and / or turning a lock cylinder with a key.

[0016] The automatic latches can each be designed as latch bolts. The latch bolt can be slidably mounted and extendable (translational movement along the central longitudinal direction of the latch bolt). The latch bolt can have a latch head (free, possibly protruding end) and a latch tail (rear end, always located within a housing of the locking device). The latch bolt is pre-tensioned, particularly in the extension direction, by means of a spring. The latch bolt can have a chamfer at the latch head. The latch bolt is movable between a retracted position (unlocking position) and a fully extended position (locking position).

[0017] The locking device may include additional secondary locks, each of which has a pivot bolt as its locking element. The pivot bolt may be mounted to pivot about an axis (pivot bolt axis). The pivot bolt may be pivotable between a pivoted position (unlocking position) and a pivoted position (locking position). A spring (e.g., a tension spring) may act on the pivot bolt, biasing it in the pivoting direction, i.e., to pivot outwards.

[0018] The locking module can include a bolt for locking all automatic latches of the locking device in the unlocked position. The bolt can be designed to engage a recess in the locking device's drive rod when activated, thus blocking the drive rod when the automatic latches are in the unlocked position. Advantageously, by locking all automatic latches in the unlocked position, the locking module prevents the door or window equipped with the day latch and locking device from automatically or spontaneously assuming the locked position when it is closed. In the deactivated state, the bolt cannot engage the recess and block the drive rod. In the deactivated state, the automatic latches are unaffected by the locking module and are therefore released by the locking module.

[0019] The locking module may contain a spring, in particular only a single spring. The spring may be designed as a tension spring or a compression spring.

[0020] The locking module can be attached to the sash of the door or window, and the retaining module can be attached to a frame of the door or window, preferably by means of a screw connection. This is a particularly important reason why the day release device can be retrofitted very easily to an existing door or window with a locking mechanism.

[0021] Advantageously, retrofitting eliminates the need to replace a lock in the existing locking mechanism. This makes the day latch compatible with standard lock cases, thus reducing the number of lock case variations. If necessary, the recess for the drive rod may need to be milled during the retrofit.

[0022] The invention thus solves the underlying problem of providing a day release device that has improved properties, in particular is reliable and can be retrofitted to a door or window with a locking device.

[0023] In a preferred embodiment, the locking module can have an operating slide for switching between the activated and deactivated states. The operating slide can be easily operated manually by a user, for example, with one or two fingers (one-handed operation). The operating slide can have a first detent position and a second detent position, with the activated state in the first position and the deactivated state in the second. The first detent position can be different from the second. The operating slide can, for example, indirectly actuate the bolt. The direction of actuation of the operating slide and the direction of movement of the bolt can be orthogonal to each other. Preferably, the first and second detent positions are designed to prevent unintentional actuation of the operating slide.

[0024] Advantageously, the locking module can have a pin. In the activated state, and when the door or window is closed and equipped with the day release device, the pin is held by the retaining module. In the deactivated state, the pin is not held by the retaining module. The pin can also be referred to as a projection.

[0025] Advantageously, the pin can assume a holding position in the activated state and a release position in the deactivated state. In the holding position, the pin can be held by the holding module. In the release position, the pin cannot be held by the holding module. The pin can be biased in the release position towards the holding position, particularly by means of a spring. Preferably, and especially exclusively, the pin can be moved from the release position to the holding position by means of a spring force. The pin can be moved into the holding position or the release position by means of the operating slide. Advantageously, this allows a user to switch between the activated and deactivated states and simultaneously move the pin into the holding or release position when operating the operating slide.

[0026] Specifically, the pin can be arranged on the operating slide. The pin can be attached to the operating slide, for example, by means of a screw connection. Alternatively, the pin and the operating slide can be manufactured as a single unit. The pin arranged on the operating slide advantageously improves the user's grip and operation of the operating slide and enables a compact design for the day release device.

[0027] In a preferred embodiment, the retaining module can include a retaining spring or a retaining magnet. In the activated state, and when the door or window is closed and equipped with the day release device, the pin is held by the retaining spring or the retaining magnet. In the deactivated state, the pin is not held by the retaining spring or the retaining magnet. The pin can be held circumferentially by the retaining spring. The retaining spring can be a clamping spring. The retaining spring can exert a clamping force on the pin when the pin is held by the retaining spring. The clamping force of the retaining spring can depend on the diameter of the pin. For example, a higher clamping force can be achieved with larger diameters. The force required to open the closed door or window can also depend on the clamping force of the retaining spring when the pin is held by the retaining spring.Advantageously, the force required to open the door or window can be adjusted by appropriately selecting the diameter of the pivot. The pivot can be magnetic, and in particular, it can be made of steel. The pivot can be held by the holding magnet by magnetic force. In particular, the pivot can be held by the holding magnet without contacting the holding module. The force required to open the closed door or window can depend on the magnetic force of the holding magnet when the pivot is held by it. Advantageously, using the holding magnet reduces or completely eliminates wear on the pivot and / or the holding module.

[0028] Advantageously, the retaining module can have a recess. In the deactivated state, and with the door or window closed and equipped with the day release device, the pin is positioned within the recess. The pin can be positioned within the recess without contacting the retaining module and / or the recess. Advantageously, frictional forces between the pin and the recess are avoided when inserting or removing the pin from the recess. This allows the pin to be inserted into or removed from the recess without resistance.

[0029] Advantageously, the retaining module can comprise a housing and a retaining element. The retaining element includes the retaining spring or retaining magnet and the recess. The retaining element is movably mounted on or in the housing, in particular within the housing. The retaining element may be movable only along one translational direction, in particular along a longitudinal axis of the retaining element. The retaining element may be formed in one piece. Advantageously, by moving or movably mounting the retaining element relative to the housing, manufacturing tolerances and / or sagging of the door or window sash can be compensated for. The retaining element may have a defined number of cups, in particular 4, 6, or 8 cups.The domes can advantageously increase frictional resistance between the retaining element and the housing to counteract unwanted movement of the retaining element, in particular maintaining a self-adjusted position of the retaining element.

[0030] In another possible embodiment, the retaining module can have a catch device. In the activated state, and when the door or window is closed and equipped with the day release device, the pin is held by the catch device. In the deactivated state, the pin is not held by the catch device. The pin can be held circumferentially by the catch device. The catch device can have at least one catch element. The catch element can exert a clamping force on the pin when the pin is held by the catch device. The catch device can have an elastic element, in particular a spring. The catch element can be pre-tensioned against the pin by the elastic element when the pin is held by the catch device.The force required to open a closed door or window can depend on the clamping force of the catch device when the pin is held by the catch device. Advantageously, the required force to open the door or window can be adjusted by selecting a suitable catch device.

[0031] In another conceivable embodiment, the retaining module can have a recessed element. In the activated state, and with the door or window closed and equipped with the day release device, the pin is located at least partially within the recessed element. In the deactivated state, the pin is located outside the recessed element. The pin can be spring-loaded against the recessed element when it is located within the recessed element. When the door or window is closed, the pin can be pressed against the recessed element in such a way that it slides over an edge of the recessed element and is then pushed into the recessed element by the spring, so that the pin is located within the recessed element.When the door or window is opened, the pin can be pressed against an inner side wall of the recess element in such a way that the pin pre-tensions the spring and slides over the edge of the recess element, thus disengaging from it. The force required to open the closed door or window may depend on the force required to remove the pin from the recess element.

[0032] Specifically, the pin can include a retaining section. The retaining section can have a rectangular, oval, or elliptical cross-section. The pin is movable, in particular exclusively, by means of a rotational movement of the pin between the retaining position and the release position. In the activated state, and when the door or window is closed and equipped with the day release device, the retaining section is held by the retaining module. In the deactivated state, the retaining section is not held by the retaining module. The pin can be rotatable about a longitudinal axis of the pin. The pin can be rotated into the retaining position or into the release position by means of the operating slide. The pin can be arranged on a shaft. The shaft can be rotatably mounted on a housing of the locking module by means of a rotary bearing.The operating slide can have a rack segment and the pin can have a gear, the gear engaging with or meshing in the rack segment to rotate the pin into the holding or release position when the operating slide is actuated. Advantageously, this allows a user to switch between the activated and deactivated states and simultaneously rotate the pin into the holding or release position when the operating slide is actuated.

[0033] The main lock and the secondary lock(s) can be attached to a faceplate of the locking device. The main lock and the secondary lock(s) can be spaced apart from each other along the faceplate, for example, by at least 20 centimeters. Advantageously, the main lock and the secondary lock(s) have spatially separated locking points, which increases the security of a locked door or window. The main lock and the secondary lock(s) can be coupled to each other by means of the drive rod in such a way that the automatic latch(s) simultaneously assume the unlocked position.

[0034] The locking module can be attached to the faceplate, in particular by means of a screw connection. Preferably, the locking module can be attached to the faceplate between the main lock and the secondary lock or one of the secondary locks. The locking module can have a bolt for locking the automatic latch(s) in the unlocked position. The bolt can be designed to engage in a recess in the drive rod when activated, thus blocking the drive rod when the automatic latch(s) are in the unlocked position. Advantageously, by locking all automatic latches in the unlocked position, the locking module prevents the automatic or self-engaging locking of the door or window equipped with the locking device when it is closed. In the deactivated state, the bolt cannot engage in the recess and cannot block the drive rod.

[0035] As already indicated above, the aforementioned task is also solved by a door or window arrangement with the features of the further subordinate claim.

[0036] The door or window assembly, in particular a door or window, comprises a frame that defines an opening and a sash that is pivotally mounted on the frame. In a closed position, the sash closes the opening, and in an open position, it releases the opening. The door or window assembly further comprises a locking device according to the invention as previously described. The retaining module can be attached to the frame, preferably by means of a screw connection. The retaining module and / or the locking module can be arranged such that, when the door or window assembly is closed, the retaining module and the locking module are opposite each other.

[0037] The invention is explained in more detail below with reference to the figures, where identical or functionally identical elements are provided with identical reference numerals, possibly only once. The figures show: Fig. 1 a door or window arrangement in a schematic side view; Fig. 2 a detail and sectional view of section II of Fig. 1 with a day release device; Fig. 3 a sectional view along a line III-III of Fig. 2 ; Fig. 4 the day release device of Fig. 2 in a deactivated state in sectional view; Fig. 5 a sectional view along a line VV of Fig. 4 ; Fig. 6 a retaining element of the day release device of Fig. 2 in a perspective view; Fig. 7 a variant of the holding element of Fig. 6 in an activated state in top view; Fig. 8 the holding element of Fig. 7in the deactivated state in top view; Fig. 9 a variant of the day release device of Fig. 2 in sectional view; Fig. 10 a detail view of a section X of Fig. 9 ; Fig. 11 the day release device of Fig. 9 in the activated state in sectional view; Fig. 12 a detail view of section XII of Fig. 11 ; Fig. 13 another variant of the day release device of Fig. 2 in sectional view; Fig. 14 a detail view of section XIV of Fig. 13 ; Fig. 15 the day release device of Fig. 13 in the activated state in sectional view; Fig. 16 a detail view of section XVI of Fig. 15 ; Fig. 17 another variant of the day release device of Fig. 2 in sectional view; Fig. 18 the day release device of Fig. 17 in the activated state in sectional view, and Fig. 19 a side view in the direction of arrow XIX of Fig. 18 ;

[0038] Figure 1 Figure 10 shows a door or window assembly 10 in the form of a door in a side view. The door or window assembly 10 has a frame 12 that defines an opening 14. Furthermore, the door or window assembly 10 has a sash 16 which is attached to a Fig. 1 The section of frame 12 not shown is pivotally mounted on the frame 12. In a closed position, the sash 16 closes the opening 14, and in an open position, it releases the opening 14. Fig. 1 Figure 10 shows the closed state of the door or window arrangement.

[0039] The door or window assembly 10 includes a locking device 18, which is attached to the sash 16, for example, by means of screws. The locking device 18 is designed as a multi-point locking mechanism. In this example, the locking device 18 has a main lock 20 and two secondary locks 22, as well as two further secondary locks 21. The locking device 18 also has a motor opener 23, by means of which the drive rod 30 can be driven in the opening direction.

[0040] The main lock 20 and the secondary locks 21, 22 are attached to a faceplate 28 of the locking device 18. In this example, the distance between the locks 20, 21, 22 is at least 20 centimeters. The main lock 20 here has, by way of example, a latch 25 and a bolt 27. The latch 25 is designed as a conventional latch in this example, but can optionally be designed as a (first) automatic latch.

[0041] The auxiliary locks 21 each have a pivot bolt 24. Each pivot bolt 24 is pivotally mounted about a pivot bolt axis and can pivot between a pivoted position (unlocking position) and a pivoted position (locking position), wherein in Fig. 1 The extended position is shown.

[0042] The auxiliary locks 22 each have an automatic latch. Additionally, the auxiliary locks 22 can have a conventional latch. In the example, the locking device 18 has two automatic latches. The automatic latches of the auxiliary locks 22 are each designed as a latch bolt 26. Each latch bolt 26 is slidably mounted, and the latch bolt 26 can be moved by means of a translational movement along a central longitudinal direction of the latch bolt 26. Each latch bolt 26 can be displaced between a retracted position (unlocking position) and a fully extended position (locking position). Fig. 1 The locking position is shown.

[0043] The locking device 18 has a drive rod 30 that runs parallel to the faceplate 28. The main lock 20 and the auxiliary locks 22 are coupled to each other by means of the drive rod 30 such that the automatic latches or the latch bolts 26 can be moved from the locked position to the unlocked position. The main lock 20 and the auxiliary locks 21 can be coupled to each other via the drive rod 30 or via another drive rod running parallel to the drive rod 30. When coupled via the additional drive rod, the swing bolts 24 can be moved to the unlocked or locked position via the main lock 20.

[0044] The latch bolts 26 are spring-loaded so that, when the door or window assembly 10 is closed, the latch bolts 26 automatically assume the locked position. In the locked position and when the door or window assembly 10 is closed, the sash 16 cannot be opened except by applying force to the sash 16 in the opening direction. To open the sash 16, a lever handle 32 must be actuated using a door handle (not shown), or a cylinder lock (not shown) inserted into the main lock 20 must be actuated using a key (not shown). Such actuation moves the automatic latches or latch bolts 26 into the unlocking position.In the unlocked position, the door or window assembly 10 can be moved from the closed state to the open state by applying a force to the sash 16 in the opening direction of the door.

[0045] The locking device 18 comprises a day release device 34. The day release device 34 has a locking module 36 and a holding module 38 (in Fig. 1 (each is represented only symbolically).

[0046] In this example, the locking module 36 is arranged between the main lock 20 and one of the secondary locks 22. When the door or window assembly 10 is closed, the holding module 38 is positioned opposite the locking module 36.

[0047] Figure 2 shows a detailed and sectional view of section II according to Fig. 1 , wherein the locking module 36 and the holding module 38 compared to Fig. 1 are shown in more detail.

[0048] In this example, the locking module 36 is attached to the sleeve 28 by means of two screw connections 29.

[0049] In an activated state of the locking module 36, the automatic latches of the locking device 18 are locked in the unlocked position, and in a deactivated state of the locking module 36, the automatic latches are unaffected by the locking module 36. Fig. 2 shows the activated state and Fig. 4 Indicates the disabled state.

[0050] To lock the automatic latches of the locking device 18 in the unlocked position, the locking module 36 has a bolt 40 which is biased towards the drive rod 30 by means of a spring 42 (spring 42 only in Fig. 2(shown). The bolt 40 is engaged in a recess 44 of the drive rod 30 in the activated state due to the preload of the spring 42 when the automatic latches are in the unlocked position, see Fig. 2 The engaged bolt 40 blocks the connecting rod 30.

[0051] To switch between the activated and deactivated states, the locking module 36 has an operating slide 46. The operating slide 46 is movable in one direction parallel to the strike plate 28. The operating slide 46 can be operated by a user when the door or window assembly 10 is open. Operation by a user is easily possible with just one hand (one-handed operation), for example, directly via the operating slide 46 or via a pin 54 coupled to the operating slide 46. The operating slide 46 engages in a first detent position when the activated state is switched and engages in a second detent position when the deactivated state is switched.

[0052] The operating slide 46 is coupled to the latch 40 via a lever 48. The lever 48 is pivotally mounted on a pivot axis 49, specifically on a housing 95 of the locking module 36. The latch 40 is rotatably attached to the lever 48 on a pivot axis 41. The lever 48 has a cam 50. When the operating slide 46 is switched to the activated state, the operating slide 46 slides along the cam 50 into the first detent position and actuates the lever 48 such that the spring 42 moves the latch 40 in the direction of the connecting rod 30. In this example, the actuation direction of the operating slide 46 and the direction of movement of the latch 40 are orthogonal to each other.

[0053] The first detent position is defined by a recess 52 in the lever 48. When the deactivated state is engaged by means of the operating slide 46, the operating slide 46 slides along the cam 50 into the second detent position, thereby actuating the lever 48 such that the bolt 40 is pulled out of the recess 44 by the lever 48. In the deactivated state, the connecting rod 30 is not blocked and all automatic latches are released. In the second detent position, the operating slide 46 is clamped between the lever 48 and the strike plate 28 by the spring 42.

[0054] The locking module 36 has a pin 54. In this example, the pin 54 has a circular cross-section. The pin 54 is arranged on the operating slide 46. The pin 54 is attached to the operating slide 46 by means of a screw connection. In the activated state, the pin 54 assumes a holding position, and in the deactivated state, a release position.

[0055] When the operating slide 46 is actuated, the pin 54 is simultaneously moved. When the operating slide 46 is used to switch to the activated or deactivated state, the pin 54 is simultaneously moved to the holding or release position. Fig. 2 shows the pin 54 in holding position and Fig. 4 shows pin 54 in release position.

[0056] In the activated state and in the closed state of the door or window arrangement 10, the pin 54 is held by the holding module 38, see Figs. 2 and 3 In the deactivated state and in the closed state of the door or window assembly 10, the pin 54 is not held by the retaining module 38, see Figs. 4 and 5 .

[0057] The holding module 38 has a housing 56 and a holding element 58. The holding element 58 without housing 56 is in Fig. 6The housing 56 of the holding module 38 is, for example, attached to the frame 12 by means of a screw connection. The holding element 58 is arranged inside the housing 56. The holding element 58 is symmetrical to the image plane of the Fig. 3 Advantageously, the retaining element 58 can be used for both left-opening and right-opening doors or windows due to its symmetrical property.

[0058] The retaining element 58 has a retaining spring 60 in the form of a clamping spring and a recess 62, see Fig. 6 The retaining spring 60 and the recess 62 are arranged next to each other.

[0059] In the activated state and in the closed state of the door or window assembly 10, the pin 54 is held circumferentially by the retaining spring 60, see Fig. 3When the closed sash 16 is opened in the activated state, a clamping force of the retaining spring 60 must be overcome to push the pin 54 out of the retaining spring 60. Therefore, opening the closed door or window assembly 10 requires a force acting on the sash 16 that exceeds a limiting opening force, where the limiting opening force is greater than the clamping force of the retaining spring 60. The limiting opening force is, for example, 25 Newtons.

[0060] In the deactivated state and in the closed state of the door or window assembly 10, the pin 54 is in the release position and arranged within the recess 62, see Fig. 5 .The pin 54 is not held by the retaining spring 60. The pin 54 can be removed from the recess 62 without resistance. If the closed sash 16 is opened in the deactivated state, the retaining element 58 does not interact with the pin 54. To open the closed door or window assembly 10, a force reduced by the clamping force of the retaining spring is required on the sash 16 when all automatic latches are in the unlocked position.

[0061] The holding module 38 includes at least one free space 64 that allows movement of the holding element 58 within the housing 56. Figs. 3 and 5 Two clearances 64 are shown. The at least one clearance 64 is arranged such that the retaining element 58 can only move in the direction of a longitudinal axis 59 of the retaining element 58. The retaining spring 60 and the recess 62 have chamfers 66, see Fig. 6 .

[0062] If manufacturing tolerances and / or sagging of the wing 16 occur, the pin 54 slides along one of the guide ramps 66 when the wing 16 closes, thereby moving the retaining element 58 in such a way that the manufacturing tolerances and / or the sagging of the wing 16 are compensated for. The retaining element 58 has six cups 68. The cups 68 increase the frictional resistance between the retaining element 58 and the housing 56. This counteracts any unintentional movement of the retaining element 58.

[0063] Figs. 7 and 8 Each shows a top view of a variant 58' of the retaining element of Fig. 6 , which largely corresponds to the retaining element 58 described above. To avoid repetition, reference is therefore made to the preceding explanations, and the following discussion will focus primarily on the differences.

[0064] The retaining element 58' has a retaining magnet. The retaining magnet is arranged inside the retaining element 58'.

[0065] Due to the arrangement of the holding magnet within the holding element 58', the holding magnet is visible in the top view from Figs. 7 and 8 Not recognizable (covered).

[0066] The holding magnet is a bar magnet, with the magnetic field lines 70 of the holding magnet penetrating a further recess 72. The pin 54 is made of steel and is magnetic. In the activated state and in the closed state of the door or window assembly 10, the pin 54 is held contactlessly in the further recess 72 by the holding magnet by a magnetic force. The magnetic field lines 70 penetrate the pin 54, see Fig. 7. This means that opening the closed door or window arrangement 10 requires a force acting on the sash 16 which exceeds a limiting opening force, where the limiting opening force is greater than the magnetic force of the holding magnet.

[0067] In Fig. 8 The deactivated and closed states of the door or window assembly 10 are shown. The pin 54 is positioned within the recess 62. The pin is not penetrated by the magnetic field lines 70 of the holding magnet and is therefore not held by the holding magnet. To open the closed door or window assembly 10, a force reduced by the magnetic force of the holding magnet is required on the sash 16 when all automatic latches are in the unlocked position.

[0068] Figs. 9 to 12 shows a variant 34' of the day release device of Figs. 2 to 6For identical and functionally equivalent elements, the same reference symbols are used, and in this respect, reference is made to the previous explanations. Figs. 1 to 8 Reference has been made. The following discussion will focus primarily on the differences.

[0069] The pin 54' is slidably mounted parallel to a longitudinal axis 74 of the pin 54'. The pin 54' can be extended and retracted. The pin 54' has a pin head 76 and a retaining section 78. The pin 54' is biased towards the sleeve 28 by means of a spring 80. The spring 80 contacts the pin head 76.

[0070] In the holding position, the holding section 78 protrudes partially from the housing 95 of the locking module 36, so that the holding module 38' holds the pin 54' on the holding section 78 when the door or window assembly 10 is in the closed state, see Figs. 11 and 12In the release position, the pin 54' is retracted into the housing 95 of the locking module 36 in such a way that the holding module 38' does not hold the pin 54' on the holding section 78 when the door or window assembly 10 is in the closed state, see Figs. 9 and 10 .

[0071] The pin head 76 is arranged within the housing 95 of the locking module 36 in the release and holding positions. The pin head 76 has a lug 82. The lever 48' rests against the lug 82. The lever 48' has a projection 51 that rests against the lug 82. The lug 82 is biased against the projection 51 by the spring 80.

[0072] The pin 54' is coupled to the lever 48' and the operating slide 46' via the lug 82. The lug 82 is coupled to the lever 48', in particular to the extension 51, such that when switching from the deactivated state to the activated state, the lug 82 is not pulled along by the lever 48', in particular by the extension 51. The lug 82 is not attached to the extension 51. The pin 54' is moved from the release position to the holding position, in particular only, by means of a spring force from the spring 80.

[0073] Advantageously, due to the coupling of the lever 48' with the pin 54' by means of the lug 82 and the extension 51, a user can press on the pin 54' in the holding position without moving the locking module 36 from the activated state to the deactivated state. When switching to the deactivated state, the lever 48' engages the lug 82 and moves the pin 54' into the release position, thus pre-tensioning the spring 80.

[0074] The operating slide 46', which can be operated by one hand, has a projection 47. The projection 47 contacts the lever 48'. The lever 48' has a cam 50' with a first recess 52 and a second recess 53. When the operating slide 46' is switched to the activated state, the projection 47 slides along the cam 50' into the first detent position, thereby actuating the lever 48'. The first detent position is defined by the first recess 52. When the operating slide 46' is switched to the deactivated state, the projection 47 slides along the cam 50' into the second detent position, thereby actuating the lever 48'. The second detent position is defined by the second recess 53.

[0075] The holding module 38' has a snap-lock device 83. The snap-lock device 83 has a first snap element 84 and a second snap element 86. The first snap element 84 is pre-tensioned in the direction of the second snap element 86 by means of an elastic element (not shown). The second snap element 86 is also pre-tensioned in the direction of the first snap element 84 by means of an elastic element (not shown). Both snap elements 84 and 86 each have an entry chamfer 88.

[0076] When the pin 54' is in the holding position, it slides along the guide ramps 88 as the sash 16 closes, pre-tensioning the elastic elements until the pin 54' engages in the catch device 83 and is held circumferentially by the two catch elements 84, 86. The elastic elements press the two catch elements 84, 86 against the pin 54' to hold it in place. If the closed sash 16 is opened in this activated state, a clamping force of the catch device 83 must be overcome to remove the pin 54' from the catch device 83.

[0077] Figs. 13 to 16 shows another variant 34" of the day release device from Figs. 2 to 6 Identical reference symbols are used for identical and functionally equivalent elements, and in this respect, reference is made to the previous explanations. Figs. 1 to 12 Reference has been made. The following discussion will focus primarily on the differences.

[0078] The pin 54'' has a holding section 78' and a drive section 94, see Fig. 14 or 16 The pin 54" is rotatable about its longitudinal axis 74. A shaft 92 is arranged on the drive section 94. The pin 54" and the shaft 92 are formed as a single unit. The shaft 92 is rotatably mounted on the housing 95 of the locking module 36 by means of a rotary bearing 93. The pin 54" is rotatably attached to the housing 95 by means of the shaft 92. The pin 54" is moved between the holding position and the release position by means of a rotational movement.

[0079] The retaining section 78' has an elliptical cross-section. The retaining module 38' has an opening 39 that is larger than the smallest diameter of the elliptical retaining section 78' and smaller than the largest diameter of the elliptical retaining section 78'. In the release position, the pin 54'' is rotated in such a way that it can be inserted into the retaining module 38' through the opening 39 practically unimpeded. In the holding position, the pin 54'' is rotated in such a way that it cannot be removed from the retaining module 38' unimpeded. In the holding position and in the closed state of the door or window assembly 10, the retaining section 78' is held by the retaining module 38', see [reference]. Figs. 15 and 16 In the release position, the holding section 78' is not held by the holding module 38', see Figs. 13 and 14 .

[0080] The holding module 38' has a previously described snap-lock device 83. Reference is made to the preceding descriptions regarding the snap-lock device 83. In the holding position, the holding section 78' is held circumferentially by the two snap elements 84, 86. In the release position, the holding section 78' is not held by the two snap elements 84, 86.

[0081] The drive section 94 is arranged within the housing 95 of the locking module 36 in both the release and holding positions. The drive section 94 has a gear 96. The gear 96 engages with a rack segment 98. The rack segment 98 is integrally formed with the operating slide 46". The operating slide 46" can be operated with one hand. When switched to the activated state by means of the operating slide 46", the rack segment 98 drives the gear 96 to rotate the pin 54" into the holding position. When switched to the deactivated state by means of the operating slide 46", the rack segment 98 drives the gear 96 to rotate the pin 54" into the release position.

[0082] Figs. 17 to 19 shows another variant 34‴ of the day release device of Figs. 2 to 6For identical and functionally equivalent elements, the same reference symbols are used, and in this respect, reference is made to the previous explanations. Figs. 1 to 16 Reference has been made. The following discussion will focus primarily on the differences.

[0083] The pin 54‴ is arranged on the operating slide 46‴. The pin 54‴ and the operating slide 46‴ are integral parts. When the operating slide 46‴ is moved, the pin 54‴ is moved simultaneously. The operating slide 46‴ can be operated with one hand. The pin 54‴ has an arcuate or semicircular positioning surface 100.

[0084] The holding module 38" has a recess element 102. The recess element 102 has an opening 104, which is bounded by a rim 106, see Fig. 19 .

[0085] In the release position, the pin 54‴ is arranged outside the recess element 102, see Fig. 17In the holding position of the pin 54‴ (not shown), the operating slide 46‴ abuts a spring 108 of the locking module 36. The pin 54‴ assumes the holding position only when the door or window assembly 10 is open and in the activated state.

[0086] In the activated state and in the closed state of the door or window assembly 10, the pin 54‴ is biased against the recess element 102 in a further holding position by means of the spring 108 and via the operating slide 46‴, see Fig. 18 The curve 50" is shaped in such a way that the lever 48‴ does not transmit any force to the bolt 40 when the pin 54‴ is moved between the holding position and the next holding position.

[0087] When the pin 54‴ is in the holding position (not shown), when the wing 16 is closed, the positioning surface 100 is pressed against the recess element 102 and the pin 54‴ slides along the recess element 102 in such a way that the operating slide 46‴ is displaced and the spring 108 is tensioned until the positioning surface 100 slides over the edge 106 and the spring 108 pushes the pin 54‴ through the opening 104 into the recess element 102 after overcoming the edge 106, so that the pin 54‴ is partially arranged in the recess element 102 and assumes the further holding position. When the wing 16 is opened, the pin 54‴ is pressed against an inner side wall 110 of the recess element 102 in such a way that the operating slide 46‴ is displaced and the spring 108 is pre-tensioned until the pin 54‴ slides over the edge 106 of the recess element 102 and leaves the recess element 102.
