Description

Technical Field

[0001] The present invention relates to a displacement device for forcibly displacing sashes, especially sliding sashes, window sashes or doors relative to a window sash or door frame as described in the preamble of claim 1, wherein the direction of displacement is transverse to, especially perpendicular to, the main plane of the window sash or door. Background Art

[0002] In various embodiments, movable sashes are known as sliding sashes or movable parallel sliding sashes of window sashes or doors, and in the simplest case, the movable sashes consist of a sash as a sliding sash which is movably arranged in an external frame for opening and closing, and another door element or window element (e.g. a vertical sash or a fixed domain) which is also arranged in the frame.

[0003] The closed sliding sash can be locked to the frame on the side facing away from the door element or window element by operating the operating mechanism provided in the sash, and is thus protected from unauthorized opening. The sliding sash with parallel placement that can be moved in parallel is often movably accommodated above or below the sliding sash. When opening, usually with the aid of an operating handle on the sliding sash, the sliding sash is placed perpendicular to the main plane of the frame with the sealing part, whereby the sliding sash is more easily moved. The opened sliding sash can be pushed in front of the vertical sash located next to it. In the open position of the sash relative to the frame, the parallel placement sash with a smaller placement size is only constructed for free pushing. When closing, the sliding sash is pulled onto the frame, wherein the sealing part of the sash is pressed against the frame. Opening and closing can also be achieved by electric, hydraulic or pneumatic actuators.

[0004] A device is known from DE7127697U. By means of an offset movement transverse to the plane of the sliding leaf frame, a sealing of the sliding frame leaf relative to the door and window wall frame can be achieved. A pair of pulleys held by a pulley support is used here, which are slidably supported on bolts fixed to the sliding frame leaf. The sliding leaf also contains a movably supported frame strip, which carries the sliding profile. If the frame strip moves at this time, the entire sliding leaf moves due to the profile starting against the fixed sliding element, so that the bolt penetrates the sliding element and the spring is compressed. If the frame strip is moved back again, the spring relaxes and the sliding leaf is guided back to its starting position again.

[0005] The pulley pair has a narrow middle area on the bolt of the push-pull sash. In the present invention, in order to make the push-pull sash perpendicular to the plane of the door and window wall frame and offset relative to the door and window wall frame, the sliding profile is supported by the wedge surface of the sliding element by means of a wedge surface. The disadvantage here is that due to the asymmetric force action, a torque acts on the bolt, and the torque is transmitted from the bolt to the pulley through the narrow part of the pulley support part, and is then introduced into the slide rail by the pulley. The torque causes the bolt to tilt and get stuck in the accommodating element and the pulley support part, so that the aforementioned structure is difficult to move. This structure is structurally expensive, requires space, and is not suitable for providing a low-cost implementation in the case of greater load reduction (when more than two pulley pairs are required).

[0006] EP 0 600 102 A1 discloses an accessory for forcibly placing a leaf in a tipped-over position or a push-pull position.

[0007] A sliding door unit is known from DE102016119515A1, which has a door and window frame and a sliding door movable in the door and window frame, wherein at least one accessory is constructed. A plurality of locking bolts that can be engaged with the attached locking element are provided at the height of the frame profile of the door and window frame. A plurality of locking bolts that are respectively engaged with the closed housing on the door and window frame are also optionally provided at the height of the frame profile of the sliding door. In one design, a blocking element is provided, and if the locking bolt is in the driving-in position, the blocking element blocks the operation of the sliding door locking. When the locking bolt is in the driving-out position and can be locked by means of the locking element, the sliding door is locked. The blocking element can be engaged with the locking bolt or with the member connected to the locking bolt, so as to block the operating element for locking the sliding door in the retracted position of the locking bolt. The operating element for locking the sliding door can only be fully moved in the driving-out position of the locking bolt.

[0008] Furthermore, EP 2 778 329 B1 discloses a multi-part closing body having a fixing element for fixing to a beam and a closing element receptacle for receiving a closing element. The closing element receptacle has a slot-shaped receptacle for the closing element. A damping element is arranged between the closing element receptacle and the fixing element and dampens the impact of the closing element against the slot-shaped receptacle.

[0009] The design with the slot-shaped receiving portion is relatively complex and therefore expensive to manufacture. The disadvantage arising here is that, due to tolerances in the fittings, the closing body may tilt and get stuck, which can make the aforementioned structure difficult to move or even impossible to use.

[0010] EP2682545B1 discloses a closing device for a sliding door or sliding window, which has a supporting element fixed to a sliding sash, a fixed frame or a fixed area of ​​the sliding door or sliding window. In addition, a push-pull member that can move transversely to the supporting element is arranged on the supporting element, and the push-pull member cooperates with the closing device through a control element having an operating device of the sliding door. The latch pin and the closing body (which has a mushroom head receiving portion) are brought in by the mushroom head of the latch pin through the movement of the latch pin parallel to its longitudinal direction in a form-locked manner, wherein the mushroom head receiving portion circumferentially surrounds the mushroom head in the form of a segment, so as to displace the sliding sash perpendicularly to its plane and lock it in its push-pull direction.

[0011] The latch pin requires a precise fit in the latch receptacle. Even the slightest deviation can cause the latch bolt to tilt or get stuck, so that a secure locking operation is no longer possible. Furthermore, no braking or damping effect occurs while the locking position of the closure is held securely. Therefore, a locking sound and an uncontrolled displacement movement of the sliding door from the parallel opening position to the secure locking position relative to the frame cannot be ruled out. Summary of the invention

[0012] The object of the present invention is to provide a functionally safe, reliable and compact displacement device for a window sash or door, in particular as a sliding sash placed in parallel, which has a locking device, which can overcome the aforementioned disadvantages, is inexpensive and is accompanied by a good visual effect of the window sash or door, and can be assembled, adjusted and locked in a simple, fast, safe, reliable and precise manner in a sealed manner with less structural space.

[0013] According to the invention, this object is achieved by a displacement device with a locking device according to claim 1. The features of the dependent claims provide advantageous embodiments of the invention.

[0014] It is important here that the displacement device can be functionally mounted on the horizontal and vertical beams of the leaf in the circumferential direction of the groove, wherein, in the case of the displacement device being arranged at the horizontal leaf, the displacement device forcibly guides the leaf vertically into the placement position from the frame into the free operating area and guides the leaf relative to the frame during the movable displacement. According to the invention, the displacement device with the coupled locking element is fixed to the vertical beam of the leaf on the opposite closed side of the operating drive controlled by the operating handle, and the displacement device can be guided into a locked closed position or an unlocked and movable open position by means of a latching element located on the vertical frame.

[0015] Here, the locking element has a latching bolt which penetrates through a through hole of the vertical beam transversely to the main plane of the leaf and is guided displaceably in the longitudinal direction of the center axis. The latching element preferably has a recess with an opening arranged perpendicularly to the main plane of the movable leaf, into which the latching bolt of the locking element engages in a locking manner in a forced displacement from the parallel position of the leaf toward the beam of the frame.

[0016] According to the invention, an element is provided in the recess, which in the recess loads the latch bolt with an elastic force against the longitudinal axis of the latch bolt and transversely to the main plane of the leaf, so that the latch bolt is introduced into the locking element in a braking and damping manner for the locked closed position. In addition, the forced displacement of the leaf by the displacement device and the operating mechanism from the locked closed position to the open, parallel position for the leaf movement relative to the frame is supported by the element in the recess of the latch element through the elastic force of the reaction to the latch bolt, and the locked closed position is accompanied by the latch bolt arranged on the leaf being embedded in the latch element fixed to the frame. The leaf is advantageously pressed into the open, parallel position during the forced opening, which simplifies the operation of the leaf. In addition, the force-loaded element supports the locked position of the latch bolt in the recess of the latch element, preventing undesired movement of the movable leaf by reducing the freedom of movement.

[0017] The resulting dimensional deviations and tolerances can be automatically compensated by the free space in the recess by means of the limiting measures of the force-loaded element of the latching element relative to the latching bolt. The locking and unlocking of the latching bolt in the latching element arranged on the frame can be achieved by the element loaded with a spring force without tilting or difficulty in movement. In addition, the locking is implemented in a damping and braking manner by the element loaded with a spring force.

[0018] For a continuous and securely maintained engagement of the latch bolt in the recess of the latch element circumferentially, the element is displaced toward the inner wall of the recess. Preferably, during the forced controlled locking process, from a parallel position of the movable leaf relative to the frame, the movable leaf relative to the frame is locked in a braked and play-free manner when the latch bolt enters into the opening and then into the recess, with the impact of the elastic element. With the forced controlled placement of the leaf relative to the frame in the parallel and movable position for unlocking, the latch bolt is forcibly displaced out of the recess of the latch element through the opening into the free operating area. The elastic element automatically assumes a position of reduced space in the recess with the departure from the inner wall, which position is simultaneously the initial position of the elastic element in the locking element.

[0019] It is functionally and manufacturing-technically advantageous if the latching element is formed from a first closing element and a second closing element. Here, the first closing element has a recessed hole for a fastening element, preferably a fastening screw, arranged on the visible surface for fastening the frame to the beam. The first and second closing elements together form a one-piece structural unit by a form-fitting or force-fitting connection.

[0020] In order to securely and reliably retain the latch bolt in the latch element, the first closing element has a hollow body in the form of a concave housing, which has a recess. The second closing element is designed to be almost flat. In addition, the force-loaded element is arranged on the closing element, which protrudes convexly from the flat surface of the closing element into the free operating area. In the assembled state and when the closing element is effectively connected to the closing element, the element is oriented toward the closing element and is arranged in the recess in an adjustable manner by positioning the loading position of the reaction force.

[0021] Preferably, the second closing element is made of a spring-elastic material, for example a plastic material or a spring plate. The material selection of the closing element results in a simple structure and simple production, so that the elastic element is also made in a one-piece construction consisting of the closing element, for example by an injection molding process or by a molding technique.

[0022] Fixed in its position and loaded with force, the latch bolt is controlled to enter the opening of the latch element by an operating mechanism with a displacement device. As the free end of the latch bolt rests on the elastic element, the clamping effect increases towards the end of the recess until the latch bolt advantageously occupies a secured position in the latch element. In short, the elastic element is infinitely spaced apart from the flat inner wall of the second closing element in the recess at an acute angle, which increases towards the end of the recess. The flap-like shaping of the elastic element is such that the opening is connected to the flat surface of the closing element and is movable in the recess in a free operating area, extending towards the end and separated from the closing element. Here, the elastic element is in a position in which it was originally not loaded. In the position in which the elastic element is loaded, the acute angle is reduced.

[0023] The element is preferably made of plastic material due to good sliding properties for the latch bolt to slide into the locked closed position and cost-effective production for achieving a spring effect in the element. However, other materials are also possible, such as the aforementioned spring plate or a plate with a spring loaded with force. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 1 In the front view, a window or door 4 is shown, which has a fixedly mounted sash or a fixed door region 39 in a fixedly standing frame 3 and is also equipped with a movable sash 2. Figure 1 As can be seen, the movable leaf 2 can be moved relative to the fixedly standing frame 3 and relative to the fixedly mounted leaf or door region 39. Figures 1 to 7 The closed position of the locking device shown is adjusted to the Fig. 9 and Fig.10 and can then be moved horizontally from the region of the through-opening of the stationary frame 3 to in front of the fixedly mounted wing or fixed door region 39.

[0041] In order to achieve two positions for parallel placement and movement of the leaf 2 relative to the fixed frame 3 and relative to the fixedly mounted leaf or fixing area 39, a special fitting arrangement is provided between the leaf 2 and the fixedly mounted frame 3, namely the so-called parallel placement-pushing fitting. Figure 1 and Figure 2 The operating handle 40 on the movable wing 2 has an operating mechanism 5 for operating the transmission system, which has Figure 2 The displacement device 1 according to the invention of the locking device 42 shown in FIG. Figure 2 Another locking device 41 and the driving element 23 in the embodiment. In addition, according to Figure 1The slide rail 21 is fixed on the frame 3 of the present invention, and the slide rail 21 is fixed on the frame horizontal lower beam and the frame horizontal upper beam 43, 44. The locking device 41 with a latch is located on the operating transmission system of the operating mechanism 5, and is connected with the closing plate arranged on the frame 3, contributing to the locking operation together, and promoting the longitudinal movement and lateral movement of the push-pull wing 2 (in certain cases, through the oblique latch and the closing plate arranged on the frame 3 and the operating mechanism 5).

[0042] according to Figures 3 to 7 , the displacement device 1 has a control element 8, which is formed by a control web 9 and has a control cam or guide element 11, 11' at a free first end 10, which can be rotatably controlled on a cover rail 15 about a pivot point 16 at a free second end 14. In addition, the displacement device 1 is formed identically on the respective horizontal lower and horizontal upper beams 29, 30 of the movable wing 2. In the displacement device 1, it must be taken into account that its frame-side articulation position formed by the control cams 11, 11', i.e. the control cams 11, 11', according to Figure 1 The horizontal guide rails 21 can be permanently embedded in the horizontal lower beam and the horizontal upper beam of the frame or in the crossbeams 43, 44 of the fixedly standing frame 3, and the synchronous movement of the control elements 8 provided for external placement is ensured.

[0043] By following Figure 3 The control contour 12 provided on the control connecting plate 9 makes the rotatable displacement of the control connecting plate 9 possible, and the control contour and the control bolt 13 act together, and the control bolt is located on the operating transmission rod 7 of the displacement device 1 and is coupled to the transmission rod of the operating mechanism 5. The control bolt 13 is preferably configured as a large-head bolt, and is moved along with the reciprocation of the operating mechanism 5 through the control contour or recess 70 of the control connecting plate 9 provided in the longitudinal direction of the movable operating transmission rod 7. Here, the control contour 12 and the control bolt 13 are coordinated with each other, so that when the control bolt 13 moves, the control connecting plate 9 can be pivoted on the free second end 14 on the fixed pivot point 16 provided on the cover rail 15, transversely to the circumferential direction 6 of the tongue and groove. The pivot point 16 is completed by the large-head bolt and by the control bolt according to Figure 3 The control connecting plate 9 is held in a fixed position in a rotatable and safe manner by means of the large-headed bolt of the control bolt 13 .

[0044] exist Figure 4 In order to reduce the friction resistance and driving noise between the control pin 13 and the control contour 12 , a displaceable pulley or sliding sleeve 36 is provided, which is inserted on the control pin 13 in a displaceably supported manner.

[0045] In order to forcibly control the control element 8 arranged on the displacement device 1, the control connecting plate 9 is provided with a connecting element from the sash 2 to the frame 3. By means of the forced conduction of the control connecting plate 9 of the sash 2 relative to the frame 3, and by means of vertically displacing the sash 2 from the locked closed position and the driven-in position of the displacement device 1 toward the free operating area of ​​the sash 2 relative to the frame 3, and by means of conversely displacing the sash 2 from the parallel placement position of the sash 2 relative to the frame 3 and the driven-out position of the displacement device 1 toward the closed position, the control contour 12 is arranged according to Figure 3 , Figures 5 to 7 The circumferentially closed portion forms a closed guide for the safe and reliable sliding of the control bolt 13. Figure 3 The coupling elements 19, 20 are constructed on the free ends 17, 18 of the operating transmission rod 7 of the displacement device 1, and the coupling elements are connected to the transmission rod of the operating mechanism 5 circumferentially or partially circumferentially, wherein the control cam 11 is connected to the guide rail 21 horizontally arranged on the frame 3 in a pivotable and movably guided manner by means of the horizontal arrangement of the displacement device 1 on the leaf 2. By means of the vertical arrangement on the leaf 2, the displacement device 1 has a locking element 46 on the control connecting plate 9 of the control element 8, and the locking element is locked in an operative connection with the latching element 24 arranged on the vertical beam 32 of the leaf 2 by means of the vertical arrangement of the displacement device 1 on the vertical beam 32 of the leaf 2, and the locking element 46 can be disengaged from the latching element 24 as the leaf 2 relative to the frame 3 is forcibly displaced into the parallel placement position.

[0046] The displacement device 1 and the operating mechanism 5 are arranged covered in the region of the tongue and groove between the sash 2 and the frame 3 of the window or door 4 in the standardized profile groove 26 of the sash 2. For this purpose, the operating mechanism 5 and the displacement device 1 are designed to fit in the width 27 of the profile groove 26 and are no larger than 18 mm in size, wherein the control connecting plate 9 is provided with its Figure 3 The width 28 of the groove is slightly wider in the longitudinal extension relative to the circumferential direction 6 of the groove.

[0047] For the pivoting movement of the control lug 9 of the control element 8 , the control lug 9 projects beyond the profile groove 26 toward the frame 3 in a pivotally movable manner by means of the control cams 11 , 11 ′.

[0048] In accordance with Figure 1At least one driving element 23 is arranged on the horizontal wing lower beam 29 for parallel movement. The driving element is designed to safely and reliably bear the weight of the movable wing 2, and it works together with the lower slide rail 21 in the horizontal frame lower beam 43 of the fixed frame 3.

[0049] The control cam 11 and the driving element 23 are guided and arranged offset from each other transversely to the driving direction of the sash while lying flat on a connecting strip (not shown). Here, the control cam 11 and the driving element 23 are respectively secured from falling off by guides extending parallel to each other, by grooves and connecting strips 35, and are controllably guided on the guide rail 21. A pulley or sliding sleeve 31 is rotatably inserted on the control cam 11. In order to better guide the driving element 23, the connecting strip 35 is designed to have rounded corners at its free end. The connecting strip and the connecting strip 35 visible from the inside of the building together form a guide for the control cam 11 as a groove. The displacement device 1 fixed to the sash 2 and movably connected to the frame 3 in the guide rail 21, and the driving element 23 fixed to the sash 2 and movable in the guide rail 21 on the frame 3, connect the movable sash 2 to the frame 3. For this purpose, the displacement device 1 is arranged according to Figure 1 The horizontal lower beam and the horizontal upper beam 29, 30 of the wing leaf 2, and according to Figure 3 The control element 8 is coupled with the movable transmission rod of the operating mechanism 5 with the operating transmission system when the operating handle 40 is operated, so as to forcibly and controlledly move the sash 2 from the locked closed position to a position placed and movable perpendicular to the frame 3, so as to move the sash 2 parallel to the frame 3. Independent of the displacement device 1 and the operating mechanism 5, the pulley 45 is provided according to Figure 1 The driving element 23 is automatically moved into a freely movable position together with the sash 2 by means of a placement mechanism (not shown) arranged on the driving element 23, and can be movably controlled by the guide rail 21. Due to the separate structure relative to the driving element 23, the control element 8 and the guide element with the control cam 11 of the displacement device 1 do not require any structural measures for reducing the load. When the control connecting plate 9 pivots from the pivot point 16 toward the control cam 11, an angle is generated, which determines the distance between the sash 2 relative to the frame 3 from the closed position to the parallel placement position of the sash 2 relative to the frame 3. The distance resulting from the angle enables the sash 2 to be moved on the frame 3 without contact along the axis according to the control connection plate 9. Figure 1 The arrow directions 22 are guided so as to be movable past each other.

[0050] According to Figure 1The displacement device 1 is mounted on the vertical beam 32 of the wing 2 and according to Figures 5 to 7 The displacement device 1 is adapted to the locking element 46 of the frame 3, and the locking device 42 is constructed by means of the latching element 24 arranged on the frame 3, which is located on the opposite side of the closed side of the locking device 41 of the operating transmission system, and the operating transmission system has the locking element 46 arranged there. Figure 5 and Figure 6 For this purpose, the control element 8 has a locking element 46 on the control flange 11', which is connected to the control flange 11' in a form-fitting manner (for example plugged or locked) with simple means. The locking element 46 is formed by a connecting body 47 and by a large bolt of a latch bolt 48 having a disk body 49.

[0051] It has also proven to be cost-effective if the latching insert 51 for forming the latching bolt 48 and the large bolt of the plate 49 has a recess 70 on one side of the latching element 24 for the lateral insertion of the plate 49 together with the latching bolt 48. In this case, the latching element 24 is formed by a first closing element 75 forming a housing 55, which is formed by a plate 83 and a hollow body 84 fastened to the plate. The housing 55 and the plate 83 together form a one-piece structural unit.

[0052] according to Figure 5 and Figure 6 , the connecting body 47 securely accommodates the latching bolt 48, in the present variant, in a hole 53. Not shown, the connecting body 47 also has a locking nut in the press-fit connection state, in the present embodiment a locking nut M8 in accordance with DIN 985. The latching bolt 48 is screwed into the internal thread of the locking nut by means of a thread not shown. The connection of the latching bolt 48 and the locking nut makes it possible to adjust the locking element 46 relative to the latching element 24 by means of the rotation obstacle present in the locking nut, when the latching bolt 48 is simultaneously in the safety position. The connecting body 47 also has a receptacle for the control cams 11, 11', which is also a hole 54. The connection of the control cams 11, 11' and the connecting body 47 relative to the control element 8 can be carried out in a locking manner or by a fixed form-fitting fit or force-fitting fit.

[0053] according to Figures 5 to 7The latch bolt 48 of the locking element 46 is transverse to the movement direction of the transmission rod of the operating mechanism 5 and transverse to the movement direction of the operating transmission rod 7 of the displacement device 1, and is oriented in the circumferential direction 6 of the tongue and groove, transverse to the main plane of the wing 2 at an angle of 90° in the direction away from the wing 2 and perpendicular to the visible surface of the frame 3, and perpendicular to the direction of the placement movement of the wing 2 relative to the frame 3.

[0054] In order to control the latch bolt 48 arranged on the movable leaf 2 to enter the Figure 7 The latching element 24 is fixed on the vertical beam 32 of the frame 3, the recess 70 has an opening 71 arranged perpendicular to the main plane of the movable wing 2, and the latching bolt 48 of the locking element 46 is forcibly displaced from the parallel and movable position of the movable wing 2 toward the beam 32 of the frame 3 and then lockedly embedded in the opening.

[0055] According to the invention, an element 72 is provided in the recess 70, which, as it enters the recess 70, loads the latch bolt 48 with a spring force against the longitudinal axis 73 of the latch bolt 48 and transversely to the main plane of the leaf 2, so that the latch bolt 48 is braked and damped when introduced into the locked closed position according to the invention. Figures 11 to 14 in the latch element 24.

[0056] During the forced displacement of the leaf 2 by the displacement device 1 and the operating mechanism 5 from the locked closed position, in which the latching bolt 48 arranged on the leaf 2 engages with the latching element 24 fixed to the frame 3, into the open, parallel position for the displacement of the leaf 2 relative to the frame 3, the element 72 provided in the recess 70 of the latching element 24 supports the opening and simplifies the operation by the elastic force reacting against the latching bolt 48. The tolerance between the recess 70 of the latching element 24 and the latching bolt 48 in the locked closed position is no longer taken into account by the element 72 loaded with force.

[0057] The locking and unlocking of the latch bolt 48 in the latch element 24 arranged on the frame 3 can be achieved by means of a ramp 85 provided on the opening 71 of the recess 70 for the latch bolt 48 to go up the ramp 85 from the plate 49 and by means of a Figure 8 The element 72 loaded with elastic force is realized without tilting or being difficult to move. In addition, the locking is buffered and braked by the element 72 loaded with elastic force.

[0058] according to Figures 11 to 14, the element 72 is displaced toward the inner wall 74 of the closure element 76 by the load of the latching bolt 48 in the recess 70. During the forced controlled locking process from the parallel position of the movable leaf 2 relative to the frame 3, when the latching bolt 48 enters the opening 71 and then enters the recess 70, the movable leaf 2 is braked and damped by hitting the elastic element 72. In addition, the latching bolt 48 is positioned in the recess 70 without play. Not shown, the latching bolt 48 and thus the displacement device 1 are unlocked from the recess 70 of the latching element 24 by the actuating mechanism 5 in the reverse sequence. In this case, the latching bolt 48 is forcibly displaced from the recess 70 of the latching element 24 through the opening 71 into the free actuating region for the unlocked parallel position and the displaceable position of the leaf 2 relative to the frame 3. As the contact of the locking bolt 48 on the elastic element 72 decreases, the flap-like element 72 automatically assumes its originally produced position in the recess 70 . In this case, the elastic element 72 moves away from the inner wall 74 in the recess 70 and reduces the free space in the recess 70 .

[0059] The latch element 24 is based on Figure 5 The first and second closure elements 75 and 76 are composed of a first closure element 75 and a second closure element 76. The closure element 75 is composed of a hollow body 84 and a plate 83 for forming the opening 71 and the recess 70. For fixing on the beam 32 of the frame 3, the plate 83 has a sink hole 82 that is easily accessible on the visible surface 80, and the sink hole is used for a fixing element, preferably a fixing screw. The first and second closure elements 75, 76 are connected by a form-locking or force-locking connection to form a one-piece structural unit. For this purpose, a fixing element 86 is provided on the closure element 76 on one side of the inner wall 74, and the fixing element is embedded in a recess (not shown) of the closure element 75 in a locking manner.

[0060] In addition to the other locking elements of the locking device 41, the embodiment of the locking device 42 enables the leaf 2 to be securely and reliably held relative to the frame 3 according to the Figure 5The latch bolt 48 with the disk 49 or head arranged on the free end of the pin 87 is arranged in the latch element 24 of the first closing element 75 from behind in the hollow body 84 of the recess 70 of the housing 77 of the concave configuration, wherein one side of the disk 49 is covered and the pin 87 remains freely accessible. The second closing element 76, which is designed almost as a flat surface, closes the second open side of the flat end 81 of the disk 49. The element 72 arranged on the closing element 76, which is loaded with force, protrudes from the flat surface of the closing element 76 toward the recess 70 of the hollow body 84 into the free operating area and reduces the space formed between the closing element 75 and the closing element 76.

[0061] In addition, according to Figure 5 The second closure element 76 shown is made of a spring-elastic plastic material or a spring plate. Therefore, the spring-elastic element 72 and the fixing part 86 are produced in one piece from the closure element 76, for example, by an injection molding process or a forming technique.

[0062] according to Figures 9 to 12 , the latch bolt 48 is moved into the opening 71 and further into the recess 70 by forced controlled entry of the operating mechanism 5 with the displacement device 1 into the closed position for locking the window sash or door. Here, as the acute angle 79 of the flap-shaped latching element 24 decreases to almost zero, the clamping force of the force-loaded element 72 on the latch bolt 48 increases continuously. The latching element 24 and the flat closing element 76 then form neat flat surfaces. Fig.13 and Fig.14 In the embodiment shown in FIG. 2 , the latching bolt 48 is in the locked end position in the latching element 24 , with the free end 81 of the latching bolt 48 resting against the spring element 72 and against the end 78 of the recess 70 , thereby clamping the free end 81 of the latching bolt 48 against the spring element 72 and against the end 78 of the recess 70 .

[0063] The element 72, which is infinitely adjustable and elastic, is used for adjusting the window or door 4 from the position of the movable leaf 2 relative to the frame 3 and according to the Figure 1 and Figure 2 The locked closed position of the locking devices 41, 42 is unlocked and the flap 2 is forcibly moved in a controlled manner to a parallel and movable position of the flap 2 relative to the frame 3 as shown in the arrow direction 22 for opening the flap 2. In this case, the acute angle 79 increases continuously from the flat inner wall 74 of the second closure element 76 toward the interior of the recess 70 to the originally produced starting position.

[0064] according to Figure 5 and Fig.10The flap-like shaping of the elastic element 72 is such that the opening 71 adjoins the flat surface of the closure element 76 and is movable in the free operating area in the recess 70, extending toward the end 78, and separated from the closure element 76. Here, the elastic element 72 is in a position in which it is originally not loaded.
