Description

[0001] Displacement device for the forced displacement of a sash, in particular a sliding sash, a window or a door

[0002] The invention relates to a displacement device for the forced displacement of a wing, in particular a sliding wing, of a window or a door relative to a frame of the window or door in a direction transverse, in particular perpendicular, to the main plane of the window or door according to the preamble of claim 1.

[0003] Sliding sashes as sliding sashes, or sliding and parallel sliding sashes of a window or door are known in a wide variety of designs and in the simplest case consist of a sash arranged as a sliding sash in an outer frame for opening and closing and of another door or window element, for example a passive sash or a fixed field, also arranged in the frame.

[0004] The closed sliding sash can be locked to the frame on the side facing away from the door or window element by activating an operating mechanism provided in the sash, thus securing it against unauthorized opening. Horizontally movable sliding sashes with a parallel stop device are usually mounted so that they can be moved above or below the sliding sash. When opened, usually using an operating handle on the sliding sash, the sliding sash is positioned perpendicular to the main plane of the frame with the seals, which makes it easier to run. The opened sliding sash can then be slid in front of an adjacent inactive sash. Parallel stop sashes, with a small clearance between the sash and the frame when open, are designed solely for free sliding. When closing, the sliding sash is pulled towards the frame, with the sash seals pressing back against the frame.Opening and closing is also possible via electrical, hydraulic or pneumatic actuators.

[0005] A device is known from DE 7127697 U. The offset movement transverse to the plane of the sliding sash frame enables the sash to be sealed against the outer frame. This involves pairs of rollers held by a roller bearing, which slides on a bolt attached to the sash frame. The sliding sash also houses a slidably mounted strip, which carries a run-up profile. If the strip is moved, the entire sliding sash slides against a fixed run-up element due to the profile running into it, so that the bolt penetrates the run-up element and the spring is compressed. If the strip is moved back again, the spring relaxes and ensures that the sliding sash is returned to its original position.

[0006] The pairs of rollers have a narrow central section on the bolt of the sliding sash. In order to move the sliding sash perpendicular to the plane of the frame against the frame, the ramp profile is adjusted with a wedge surface against a wedge surface of the ramp element. This has the disadvantage that, due to the asymmetrical force application, a torque is introduced into the bolt, which is transferred from the bolt via a narrow section of the roller bearing to the rollers and from there into the track. This torque leads to tilting and jamming of the bolt in the receiving element as well as in the roller bearing, so that the previously described construction is sluggish. The present construction is structurally complex, requires space, and is not suitable for providing a cost-effective solution for high load transfer that requires more than two pairs of rollers.

[0007] EP 0600102 A1 discloses a fitting for forcibly placing a sash in the tilt or sliding position.

[0008] DE 102016119515 A1 discloses a sliding door unit with a frame and a sliding door that can be moved within the frame, in which at least one fitting is installed. A plurality of locking bolts are provided along the height of a frame profile of the frame, which can be brought into engagement with an associated locking element. Alternatively, a plurality of locking bolts can also be provided along the height of a frame profile of the sliding door, each of which can be brought into engagement with a lock housing on the frame. In one embodiment, a blocking element is provided that blocks actuation of a sliding door lock when the locking bolt is in a retracted position. The sliding door is locked when the locking bolt is in the extended position and can effect locking with the locking element.The locking element can be engaged with the locking bolt or a component connected to the locking bolt to lock an actuating element for locking the sliding door when the locking bolt is in the retracted position. The actuating element for locking the sliding door is then fully movable only when the locking bolt is in the extended position.

[0009] Furthermore, EP 2778329 B1 discloses a multi-part locking piece with a fastening part for attachment to a stile and a locking element receiving part for receiving a locking element. The locking element receiving part has a slot-like receptacle for the locking element. A damping element is arranged between the locking element receiving part and the fastening part and dampens the impact of the locking element in the direction of the slot-like receptacle.

[0010] The design with a slot-like receptacle is complex to manufacture and therefore expensive. This has the disadvantage that tolerances in the fitting can cause the striker to tilt and jam, which can render the previously described design stiff or even unusable.

[0011] EP 2682545 B1 discloses a locking arrangement for a sliding door or sliding window, comprising a bearing element which is fastened to a sliding sash, a fixed frame, or a fixed panel of the sliding door or sliding window. Furthermore, a slider is arranged on the bearing element so as to be movable transversely thereto, said slider cooperating with a locking arrangement via a control element with an actuating device of the sliding door. A locking pin and a striker, which has a mushroom head receptacle, are inserted in a form-fitting manner by a mushroom head of the locking pin by a movement of the locking pin parallel to its longitudinal direction, wherein the mushroom head receptacle circumferentially surrounds the mushroom head in sections in order to displace the sliding sash both perpendicular to its plane and to lock it in the sliding direction.

[0012] The locking pin must fit precisely into the locking slot. Even the slightest deviation can tilt or jam the locking pin, preventing a secure locking action. Furthermore, a braking or damping effect that ensures a secure hold in the locked position of the locking assembly is not provided. Locking noises and uncontrolled displacement movements from the parallel, open position toward a secure locking position of the sliding door relative to the frame cannot therefore be ruled out.

[0013] The invention is based on the object of providing a functionally reliable and compact displacement device with a locking device for a window or a door, in particular a sliding sash as a parallel-positioning sliding sash, which eliminates the above disadvantages and is cost-effective with a good appearance for the window or door and can be mounted, adjusted and locked in a simple, fast, safe and precise manner with little installation space.

[0014] According to the invention, the object is achieved by the displacement device with a locking device according to claim 1. Advantageous embodiments of the invention emerge from the features of the subclaims.

[0015] What is essential here is that the displacement device is functionally mountable in the circumferential direction of the rebate on the horizontal stile of the sash and on the vertical stile of the sash. The displacement device is arranged on the horizontal sash, forcibly moves the sash vertically into a stowed position away from the frame into a free operating field, and guides the sash against the frame during a displaceable displacement. According to the invention, the displacement device is attached to the vertical stile of the sash with a coupled locking element on the opposite locking side of the actuating handle-controlled actuating gear and can be controlled into a locked closed position or an unlocked and displaceable open position with a locking element on the vertical frame.

[0016] The locking element comprises a locking bolt that extends transversely to the main plane of the sash through a through-hole in the vertical stile and is guided for displacement longitudinally relative to the central axis. The locking element preferably has a recess with an opening arranged perpendicular to the main plane of the movable sash, into which the locking bolt of the locking element engages, forcibly displacing the sash from a parallel, stowed position toward the stile of the frame.

[0017] According to the invention, an element is arranged in the recess that applies spring force to the locking bolt in the recess, counter to the longitudinal axis of the locking bolt and transverse to the main plane of the sash, so that a braked and damped insertion of the locking bolt into the locking element for a locked closed position is achieved. A forced displacement of the sash by the displacement device and the actuating mechanism from the locked closed position, with engagement of the locking bolt arranged on the sash in the locking element attached to the frame, into the open and parallel position for displacement of the sash relative to the frame, is additionally supported by the element in the recess of the locking element through the counteracting spring force on the locking bolt.During forced opening, the sash is advantageously pushed into the open and parallel position, which makes it easier to operate. Furthermore, the force-loaded element in the recess of the locking element supports the locked position of the locking bolt and prevents unwanted movement of the sliding sash by reducing its freedom of movement. Any resulting dimensional deviations and tolerances can be automatically compensated for by the free space within the recess, with further limiting measures provided by the force-loaded element of the locking element to the locking bolt. Locking and unlocking of the locking bolt in the locking element arranged on the frame can be achieved without tilting or stiffness thanks to the spring-loaded element. Furthermore, locking is dampened and braked by the spring-loaded element.

[0018] To ensure that the locking bolt is held securely and consistently within the recess of the locking element, the element moves toward an inner wall of the recess. During the positively controlled locking process, the sliding sash is preferably braked from a parallel position to the frame as the locking bolt enters the opening and then into the recess, stopping against the elastic element, and positioned to lock with zero play. With the positively controlled positioning of the sash relative to the frame for an unlocked, parallel, and movable position, the locking bolt is forcibly moved from the recess of the locking element through the opening into a free operating area.When removed from the inner wall, the elastic element automatically assumes a space-reducing position in the recess, which simultaneously represents the starting position of the elastic element in the locking element.

[0019] Functionally and technically advantageous, the locking element consists of a first locking element and a second locking element. The first locking element has countersunk holes arranged on a visible surface for fastening devices, preferably for fastening screws, for attachment to a frame member. The first and second locking elements together form a one-piece unit through a positive or non-positive connection.

[0020] To ensure the locking bolt is securely held in the locking element, the first locking element has a hollow body with a recess in the form of a concave shell. The second locking element is almost flat. In addition, the force-actuated element is arranged on the locking element, which protrudes convexly from the flat surface of the locking element into a free actuation field. In the assembled state and with the locking element operatively connected to the locking element, the element is aligned in the direction of the locking element and can be adjusted in position in the recess by applying a counterforce. The second locking element is preferably made of a spring-elastic material, for example a plastic material or a spring plate.A simple design and simple production results from the choice of material for the closure element, so that the elastic element in a one-piece construction is also made from the closure element, for example by an injection molding process or by forming technology.

[0021] Once fixed in position and subjected to force, the locking bolt is guided into the opening of the locking element by the controlled inlet of the actuating mechanism with the displacement device. As the free end of the locking bolt engages the elastic element, the clamping effect increases toward the end of the recess until the locking bolt advantageously assumes a secured position in the locking element.

[0022] In simplified terms, the elastic element is continuously spaced from the flat inner wall of the second closure element in the recess at an acute angle that increases toward the end of the recess. The flap-like shape of the elastic element is connected to the flat surface of the closure element for opening and, extending toward the end, is movable within the recess, detached from the closure element, within a freely movable area of ​​action. The elastic element is initially in an unstressed position. In the stressed position of the elastic element, the acute angle decreases.

[0023] The element is preferably made of a plastic material due to its good sliding properties for the locking bolt to move into the locked closed position and its cost-effective production due to the spring action implemented in the element. However, other materials are also possible, such as a spring plate or a plate with a force-loaded spring, as already described above.

[0024] Further advantageous embodiments are shown in the drawings. They show:

[0037] Fig. 1 of the drawing shows a front view of a window or a door 4 which has a stationary sash or a fixed door field 39 in a fixed frame 3 and which is also equipped with a movable sash 2. The movable sash 2 is adjustable relative to the fixed frame 3 and the fixed sash or door field 39 from the locked closed position indicated in Figs. 1 to 7 into a parallel, stowed position according to Figs. 9 and 10 and can then be moved horizontally from the area of ​​the passage opening of the fixed frame 3 in front of the fixed sash or the fixed door field 39, as can be seen from Fig. 1 with the indication of the arrow direction 22.

[0038] In order to enable these two positions for parallel parking and sliding of the sash 2 relative to the fixed frame 3 and to the fixedly mounted sash or the fixed field 39, a special fitting arrangement, namely a so-called parallel parking sliding fitting, is provided between the sash 2 and the fixed frame 3. In Figs. 1 and 2, this fitting comprises an actuating handle 40 on the displaceable sash 2, an actuating mechanism 5 with an actuating gear, the displacement device 1 according to the invention with a locking device 42 shown in Fig. 2 and a further locking device 41 in Fig. 2, and the running element 23. In addition, a running rail 21 is fastened to the lower and upper horizontal frame members 43, 44 on the frame 3 according to Fig. 1.A locking device 41 with bolts on the actuating gear of the actuating mechanism 5 in conjunction with a striking plate arranged on the frame 3 contribute to the locking and promote the longitudinal and lateral movement of the sliding leaf 2, if necessary in cooperation with the actuating mechanism 5 by means of bevelled bolts and striking plates on the frame 3.

[0039] 3 to 7, the displacement device 1 has a control element 8 which consists of a control plate 9 which is rotatably controlled about a pivot point 16 at the second free end 14 on a cover rail 15 and has a control cam or guide element 11, 11' at the first free end 10. In addition, the displacement device 1 is designed identically on the respective lower and upper horizontal beams 29, 30 of the movable sash 2. With the displacement device 1, it must be ensured that its frame-side articulation points, formed by the control cam 11, 11', of the control cam 11, 11' can constantly engage the horizontal guide rail 21 in the lower and upper horizontal frame beams or cross beams 43, 44 of the fixed frame 3 according to Fig. 1 and that a synchronous movement of its control element 8 arranged for deployment is ensured.

[0040] The rotatable displacement of the control plate 9 is made possible by a control contour 12 according to Fig. 3 arranged on the control plate 9, which interacts with a control bolt 13 coupled to the actuating rod 7 of the displacement device 1 and to the rod of the actuating mechanism 5. The control bolt 13 is preferably designed as a mushroom pin and passes through the control contour or recess 70 of the control plate 9 arranged in the longitudinal direction to the movable actuating rod 7 with the stroke of the actuating mechanism 5. The control contour 12 and the control bolt 13 are coordinated with one another in such a way that when the control bolt 13 moves, the control plate 9 can be pivoted transversely to the circumferential direction 6 of the fold at the second free end 14 on the cover rail 15. With the execution of the pivot point 16 by a mushroom bolt and the mushroom bolt of the control bolt 13 according to Fig.3, the control tab 9 is held in a fixed position so that it can rotate and move.

[0041] In Fig. 4, in order to reduce the frictional resistance and the running noise between the control pin 13 and the control contour 12, a movable roller or sliding bush 36 is arranged, which is movably mounted on the control pin 13.

[0042] For forced control of the control element 8 arranged on the displacement device 1, the control tab 9 represents a connecting element from the sash 2 to the frame 3. With forced transfer of the control tab 9 from the sash 2 to the frame 3 and with displacement of the sash 2 from a locked closed position and retracted position of the displacement device 1 perpendicular in the direction of a free operating field from the sash 2 to the frame 3 and vice versa from a parallel parked position of the sash 2 to the frame 3 and extended position of the displacement device 1 in the direction of the closed position, the control contour 12 according to Fig. 3, Fig. 5 to Fig. 7 is circumferentially closed and forms a securely sliding closed guide for the control bolt 13. According to Fig.3 coupling elements 19, 20 are formed on the free ends 17, 18 of the actuating rod 7 of the displacement device 1, which coupling elements form a circumferential or partially circumferentially detachable connection with the rod of the actuating mechanism 5, wherein with a horizontal arrangement of the displacement device 1 on the wing 2, the control cam 11 is pivotably and displaceably guided with the guide rail 21 arranged horizontally on the frame 3.With a vertical arrangement on the sash 2, the displacement device 1 has a locking element 46 on the control tab 9 of the control element 8, which, with a vertical arrangement of the displacement device 1 on the vertical beam 32 of the sash 2, is operatively locked to a locking element 24 arranged on the vertical beam of the frame 3 in the adjacent closed position of the sash 2 to the frame 3, and with forced displacement of the sash 2 to the frame 3 into a parallel parked position, the locking element 46 can be released from the locking element 24.

[0043] The displacement device 1 and the actuating mechanism 5 are concealed in a standardized profile groove 26 of the sash 2 in the region of a rebate between the sash 2 and the frame 3 of the window or door 4. For this purpose, the actuating mechanism 5 and the displacement device 1 are adapted in width 27 to the profile groove 26 and are dimensionally no larger than 18 mm, with the control tab 9, with its width 28 according to Fig. 3, being slightly wider in the longitudinal direction relative to the rebate circumferential direction 6.

[0044] For a pivoting movement of the control tab 9 of the control element 8, the control tab 9 with the control cam 11, 11' projects pivotably over the profile groove 26 in the direction of the frame 3.

[0045] On the lower horizontal wing spar 29 according to Fig. 1 , at least one running element 23 for parallel displacement is arranged, which is designed so that the weight of the movable wing 2 is safely carried, while it cooperates with a lower running rail 21 in the lower horizontal frame spar 43 of the fixed frame 3.

[0046] The control cam 11 and the running element 23 are guided on a web (not shown) and arranged offset from one another transversely to the running direction of the sash 2. The control cam 11 and the running element 23 are each secured against falling out by means of guides running parallel to one another through a groove and the web 35 and are guided in a controllable manner on the running rail 21. A roller or sliding bushing 31 is rotatably attached to the control cam 11. To improve the guidance of the running element 23, the web 35 is rounded at its free end. The web 35 and a web 35 visible from the inside of the building together form the guide for the control cam 11, which is designed as a groove. The displacement device 1, which is fastened to the sash 2 and movably connected to the frame 3 in the guide rail 21, and the running element 23, which is fastened to the sash 2 and displaceable on the frame 3 in the guide rail 21, connect the displaceable sash 2 to the frame 3.For this purpose, the displacement device 1 is arranged on the lower and upper horizontal beams 29, 30 of the sash 2 according to Fig. 1 and, according to Fig. 3, comprises the control element 8 which, upon actuation of the actuating handle 40 coupled to the movable rods of the actuating mechanism 5 with the actuating gear, moves the sash 2 in a forced manner from a locked closed position into a position parked perpendicular to the frame 3 and displaceable for parallel displacement of the sash 2 along the frame 3. Independently of the displacement device 1 and the actuating mechanism 5, the running element 23 according to Fig. 1 with rollers 45 is automatically moved into a freely displaceable position with the sash 2 by means of a parking mechanism (not shown) arranged on the running element 23 and can be displaced via the running rail 21. The control elements 8 and the guide elements with the.

[0047] Control cams 11 of the displacement device 1 do not require any structural measures for load transfer due to their separate construction from the running element 23. During the pivoting movement of the control plate 9 with output from the pivot point 16 to the

[0048] Control cam 11 results in an angle that determines a distance from the sash 2 to the frame 3 from the closed position to the parallel parked position of the sash 2 to the frame 3. The distance obtained from the angle enables the sash 2 to be guided past each other on the frame 3 in the arrow directions 22 according to Fig. 1 without contact.

[0049] By mounting the displacement device 1 according to Fig. 1 on the vertical spar 32 of the sash 2 and adapting a locking element 46 according to Figures 5 to 7, the displacement device 1 with a locking element 24 arranged on the frame 3 forms a locking device 42 on the opposite side to the closure side of the locking device 41 of the actuating gear with the locking element 46 arranged there. Further according to Fig. 5 and Fig. 6, the control element 8 on the control cam 11' has the locking element 46, which is positively connected to the control cam 11' by simple means, for example, pluggable or latched. The locking element 46 consists of a connecting piece 47 and a locking bolt 48 with a mushroom head bolt forming a plate 49.

[0050] It also proves cost-effective that the mushroom-shaped bolt, which forms a locking engagement 51 for the locking bolt 48 and the plate 49, has a recess 70 on one side of the locking element 24 for lateral engagement of the plate 49 with the locking bolt 48. The locking element 24 consists of a first locking element 75 forming a housing 55, which consists of a plate 83 and a hollow body 84 attached thereto. The housing 55 and the plate 83 together form a one-piece structural unit.

[0051] According to Fig. 5 and Fig. 6, the connecting piece 47 holds the locking bolt 48 in a fixed manner, in this variant in a bore 53. Furthermore, the connecting piece 47 has a lock nut (not shown) in a press connection, in this embodiment an M8 lock nut according to DIN985. The locking bolt 48 is screwed into the internal thread of the lock nut with a thread (not shown). The connection of the locking bolt 48 and the lock nut enable the locking element 46 to be adjusted to the locking element 24 while at the same time securing the position of the locking bolt 48 due to the rotation lock in the lock nut. Furthermore, the connecting piece 47 has a receptacle, also in the form of a bore 54, for the control cam 11, 11'. The connection between the control cams 11, 11' to the control element 8 and the connecting piece 47 can be made by locking or by a fixed positive or non-positive fit.

[0052] According to Fig. 5 to 7, the locking bolt 48 of the locking element 46 is oriented transversely to the direction of movement of the rods of the actuating mechanism 5 and the actuating rods 7 of the displacement device 1 in the rebate circumferential direction 6 transversely to the main plane of the sash 2 at a 90° angle in the direction away from the sash 2 perpendicular to the visible surface of the frame 3 and perpendicular to the adjustable movement of the sash 2 to the frame 3.

[0053] For a controlled entry of the locking bolt 48 arranged on the sliding sash 2 into the locking element 24 fastened to the vertical beam 32 of the frame 3 according to Fig. 7, the recess 70 has an opening 71 arranged perpendicular to the main plane of the sliding sash 2, into which the locking bolt 48 of the locking element 46 engages, forcibly displacing the sliding sash 2 from a parallel and displaceable position in the direction of the beam 32 of the frame 3 and subsequently locking it.

[0054] According to the invention, an element 72 is arranged in the recess 70, which element applies spring force to the locking bolt 48 when it is inserted into the recess 70, counter to the longitudinal axis 73 of the locking bolt 48 and transverse to the main plane of the leaf 2, so that a braked and damped insertion of the locking bolt 48 into the locking element 24 according to Figs. 11 to 14 is achieved for a locked closed position. During the forced displacement of the sash 2 by the displacement device 1 and the actuating mechanism 5 from the locked closed position with engagement of the locking bolt 48 arranged on the sash 2 in the locking element 24 fastened to the frame 3, into the open and parallel position for displacement of the sash 2 to the frame 3, the element 72 in the recess 70 of the locking element 24 supports the opening by the counteracting spring force on the locking bolt 48 and facilitates operation.Tolerances between the recess 70 of the locking element 24 and the locking bolt 48 in the locked closed position are eliminated by the force-loaded element 72.

[0055] The locking and unlocking of the locking bolt 48 in the locking element 24 arranged on the frame 3 can be achieved without tilting or stiffness by a ramp 85 arranged at the opening 71 of the recess 70 for the locking bolt 48 to run from the plate 49 onto the ramp 85 and by the spring-loaded element 72 according to Fig. 8. Furthermore, the locking is dampened and braked by the spring-loaded element 72.

[0056] According to Fig. 11 to Fig. 14, the element 72 is displaced by stress on the locking bolt 48 in the recess 70 in the direction of an inner wall 74 of a locking element 76. During the positively controlled locking process from the parallel parked position of the displaceable sash 2 to the frame 3, the displaceable sash 2 is braked and damped as the locking bolt 48 runs into the opening 71 and then into the recess 70 with a stop against the elastic element 72. In addition, the locking bolt 48 positions itself in the recess 70 without play. Not shown, the unlocking of the locking bolt 48 and thus of the displacement device 1 via the actuating mechanism 5 from the recess 70 of the locking element 24 takes place in the reverse order.In this case, the locking bolt 48 is forcibly displaced from the recess 70 of the locking element 24 through the opening 71 into a free operating area for an unlocked, parallel position and a displaceable position of the sash 2 relative to the frame 3. As the contact of the locking bolt 48 with the elastic element 72 decreases, the flap-like element 72 automatically assumes its originally established position in the recess 70. In doing so, the elastic element 72 moves away from the inner wall 74 in the recess 70 and reduces the free space in the recess 70.

[0057] According to Fig. 5, the locking element 24 consists of a first locking element 75 and a second locking element 76. The locking element 75 is composed of a hollow body 84 for forming the opening 71 and the recess 70, and of a plate 83. For attachment to the beam 32 of the frame 3, the plate 83 has easily accessible countersunk holes 82 for fastening means, preferably for fastening screws, on a visible surface 80. The first and second locking elements 75, 76 together form a one-piece structural unit through a positive or non-positive connection. For this purpose, fastening means 86 are provided on the locking element 76 on the side of the inner wall 74, which engage in a locking manner in recesses (not shown) of the locking element 75.

[0058] A secure hold of the sash 2 relative to the frame 3 in the locked closed position according to Fig. 5 is achieved, in addition to the other locking elements of the locking device 41, by the design of the locking device 42. The locking bolt 48, with a plate 49 or head arranged at the free end of a pin 87, is arranged in the form of a concave jacket 77 in the locking element 24 of the first locking element 75 in the hollow body 84 of the recess 70, engaging behind it, whereby one side of the plate 49 is covered and the pin 87 remains freely accessible. The second locking element 76, which has a nearly flat surface, closes a second open side of the flat end 81 of the plate 49.The force-loaded element 72 arranged on the closure element 76 lifts off convexly into a free actuation field from the flat surface of the closure element 76 in the direction of the recess 70 of the hollow body 84 and reduces the space formed between the closure element 75 and the closure element 76.

[0059] Furthermore, the second closure element 76 shown in Fig. 5 is made of a resilient plastic material or a spring sheet. Thus, the resilient element 72 and the fastening means 86 can be manufactured in one piece from the closure element 76, for example, by an injection molding process or by forming technology.

[0060] According to Figs. 9 to 12, the locking bolt 48 is moved by the positively controlled entry of the actuating mechanism 5 with the displacement device 1 into the opening 71 and further into the recess 70 for the locked, closed position of the window or door. The clamping force of the force-loaded element 72 on the locking bolt 48 continuously increases, with the acute angle 79 of the flap-like locking element 24 decreasing to almost zero. The locking element 24 and the flat closure element 76 then form a uniformly flat surface. In Figs. 13 and 14, the locking bolt 48 is in the locked end position in the locking element 24, with the free end 81 of the locking bolt 48 resting against the elastic element 72 and a clamping effect at the end 78 of the recess 70.Not shown, the continuously adjustable and elastic element 72 for unlocking the window or door 4 moves from the adjacent position of the sliding sash 2 to the frame 3 and the locked closed position of the locking devices 41, 42 according to Fig. 1 and Fig. 2 by the actuating mechanism 5 with the actuating rod 7 in a positively controlled manner in the direction of the parallel and sliding position of the sash 2 to the frame 3 for opening the sash 2, as shown in the direction of arrow 22. The acute angle 79 increases continuously from the flat inner wall 74 of the second locking element 76 in the direction of the inner space of the recess 70 up to an originally produced starting position. According to Fig. 5 and Fig.10, the flap-like shape of the elastic element 72 is elastically connected to the opening 71 on the flat surface of the closure element 76 and, extending toward the end 78, is movable in the recess 70, detached from the closure element 76, within a free operating field. The elastic element 72 is in an originally unstressed position.
