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 the 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. Usually, when opening 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 easier to move. 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] EP1580362B1 discloses a sliding door and a sliding window, which comprises a sliding area and a lateral boundary located in the opening direction of the sliding area, the sliding area is movable in the opening direction and the closing direction along the lateral boundary, and overlaps with the lateral boundary in the moving direction, wherein the sliding area can be locked and unlocked by means of at least one controllable locking portion, the locking portion is arranged between the sliding area and the lateral boundary in the overlapping area, and comprises locking elements on both sides, the locking elements are laterally locked to each other by means of at least one movable push rod device parallel to the main plane of the sliding area. The push-pull region is movable toward the main plane of the push-pull region into a locked state or an unlocked state, in which the locking elements cover each other transversely to the main plane of the push-pull region and prevent the push-pull region from moving in the moving direction, and in which the locking elements allow the push-pull region to move in the moving direction, wherein a steering gear train is provided between at least the push rod device and one of the locking elements cooperating therewith, by means of which a movement of the push rod device parallel to the main plane of the push-pull region can be converted into a movement of the associated locking element transversely to the main plane of the push-pull region. The latch bolt is movably guided in a guide sleeve on the push-pull region side transversely to the main plane of the push-pull region.

[0011] The latch bolt needs to fit precisely with the latch insert. Even the slightest deviation can cause the latch bolt to tilt or get stuck, making secure locking impossible. 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 accompanied by a good visual effect of the window sash or door, and can be assembled, calibrated 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 on 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 provided on the vertical frame.

[0015] Here, the locking element has a latch bolt, which passes through the through hole of the vertical beam transversely to the main plane of the wing and is guided movably in the longitudinal direction of the middle axis by a guide sleeve arranged in the through hole. Preferably, an elastic element is arranged in the hole of the guide sleeve. The cross section of the hole is larger than the cross section of the latch bolt. The elastic element clamps the latch bolt in the hole in a surrounding manner, thereby compensating the cross-sectional difference of the latch bolt relative to the hole and keeping the latch bolt in a movable position at a predetermined spacing from the inner shell surface in the hole of the guide sleeve. Due to the elasticity of the elastic element, the latch bolt is guided movably in the longitudinal direction of the middle axis of the guide sleeve by the elastic force of the elastic element. In addition, the latch bolt has a degree of freedom of movement in the hole of the guide sleeve until the inner wall of the hole. The resulting dimensional deviations and tolerances can be automatically compensated by the free space obtained in the hole relative to the latch bolt. The locking and unlocking of the latching bolt in the latching element arranged on the frame is achieved by a 360° freedom of movement around the center axis of the latching bolt without tilting or difficulty in movement.

[0016] For the continuous engagement of the latch bolt in the bore of the guide sleeve in the circumferential direction, the elastic element is formed by a plurality of individual bows, each of which extends with a free first end toward the center axis of the guide sleeve, wherein the bows preferably form a ring around the center axis of the bore, which ring is smaller than or at least equal to the circular cross section of the latch bolt. The free second ends of the bows are connected in one piece to the bore of the guide sleeve and form a one-piece component with the guide sleeve.

[0017] In order to facilitate the installation of the guide sleeve in the through-hole on the vertical beam, the circular outer surface of the guide sleeve is designed to be smaller in diameter than the through-hole of the vertical beam.

[0018] In an advantageous embodiment, the guide sleeve is fixed in the through-hole by means of a flange protruding in an annular manner at the free end on the circular outer surface of the guide sleeve, which flange bears against the outer surface of the vertical beam after assembly. Apart from the flange, the guide sleeve is located in the through-hole of the vertical beam. Preferably, the guide sleeve passes through the entire cross section of the through-hole, so that the latch bolt can be guided by the guide sleeve in the cross section of the vertical beam.

[0019] Another advantage of simple and cost-effective assembly is that the guide sleeve has a chamfer or radius arranged thereon at its free second end. The guide sleeve can be aligned at the through-hole via the chamfer and then inserted into the through-hole.

[0020] The guide sleeve is preferably made of a plastic material due to good sliding properties and cost-effective production for achieving a spring effect in the guide sleeve. However, other materials are also possible.

[0021] In order to securely hold the guide sleeve in the through-hole, retaining projections are provided at intervals on the outer shell of the guide sleeve, which extend protrudingly in the longitudinal direction of the guide sleeve and hold the guide sleeve in the through-hole of the vertical beam. However, a surrounding ring body with a hook-shaped free end protruding from the outer shell is also possible. In order to securely hold the guide sleeve in the assembled state, the retaining projection engages the connection strip of the molded wing leaf from behind in a locking manner. Another variant for securely fixing the guide sleeve in the through-hole of the wing leaf is to hold the retaining projection in the wall of the through-hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] 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 8 The locked closed position shown is adjusted to a parallel position and can then be moved in a horizontal direction from the region of the through-opening of the stationary frame 3 to in front of the stationary leaf or door region 39 .

[0038] 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. According to the displacement device 1 of the present invention, Figure 2 The locking devices 41, 42 and the driving element 23 in the embodiment of the present invention are shown in FIG. Figure 1 The 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 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 sliding wing 2 (in certain cases, through the oblique latch and the closing plate arranged on the frame 3 and the operating mechanism 5).

[0039] according to Figures 3 to 8, 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 leaf 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 cam 11, in accordance with 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.

[0040] 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 12 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 link plate 9 is held in a fixed position in a rotatable and secure manner by means of a large-head bolt of the control bolt 13 .

[0041] 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.

[0042] 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 vertical displacement of the sash 2 from the locked closed position and the driven-in position of the displacement device 1 to 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 to the closed position, the control contour 12 is arranged according to Figure 3 , Figures 5 to 8 The circumferentially closed portion forms a closed guide for the safe and reliable sliding of the control bolt 13. Figure 3 and Figure 5 The coupling elements 19, 20 are formed on the free ends 17, 18 of the operating transmission rod 7 of the displacement device 1, and the coupling elements partially or circumferentially surround the leaf 2 and the frame 3 to form a coupling connection with the transmission rod of the operating mechanism 5, wherein the control cam 11 is connected to the guide rail 21 arranged horizontally on the frame 3 in a pivotable and displaceable 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, which 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 is forced to move into a parallel placement position relative to the frame 3.

[0043] The displacement device 1 and the operating mechanism 5 are arranged covered in the region of the groove 25 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 adapted to the width 27 of the conventional 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.

[0044] 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 ′.

[0045] 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.

[0046] The control cam 11 and the driving element 23 are guided lying on a connecting strip (not shown) of the guide rail 21 and are arranged offset from each other transversely to the driving direction of the leaf 2. 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 (not shown) and connecting strips on the guide rail 21, 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 is designed with 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.

[0047] The displacement device 1 fixed to the leaf 2 and connected to the frame 3 in a movable manner in the guide rail 21, and the driving element 23 fixed to the leaf 2 and movable in the guide rail 21 on the frame 3 connect the movable leaf 2 to the frame 3. To this end, 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 cams 11, 11', an angle is generated, which determines the distance between the sash 2 and 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 1The arrow directions 22 are guided so as to be movable past each other.

[0048] According to Figure 1 The displacement device 1 is mounted on the vertical beam 32 of the wing 2 and according to Figures 5 to 8 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 vertical beam of 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 arranged there. Figure 5 and Figure 7 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 in or locked) with a simple device. Figure 5 and Figure 7 As shown, the locking element 46 is formed by a connecting body 47 and optionally by a bolt or a locking bolt 50 , also referred to as a pin, which is designed as the locking bolt 48 with a disk 49 .

[0049] It has also proven to be cost-effective if, according to an embodiment of the locking element 46 with a bolt or latch bolt 50 that is formed with a latch bolt 48 and a plate 49, the latch element 24 has different latch inserts 51, 52 that are rotated in a mirrored manner. The latch insert 51 thus has a recess that is present on one side of the latch element 24 and is used for the lateral insertion of the plate 49 together with the latch bolt 48, and the latch insert 52 has a hole for the vertical insertion of the latch bolt 50. The latch element 24 is formed by a housing 55 that is formed by a base plate 58 and a hollow body 59 that is fixed to the base plate. The housing 55 and the base plate 58 together form a one-piece structural unit.

[0050] The connecting body 47 receives the latching bolts 48, 50 in a fixed manner, in the present variant, in bores 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 bolts 48, 50 are screwed into the internal thread of the locking nut by means of a thread not shown. The connection of the latching bolts 48, 50 and the locking nut makes it possible to adjust the locking element 46 relative to the latching element 24 by means of the rotational obstacle present in the locking nut, when the latching bolts 48, 50 are simultaneously in the safety position. The connecting body 47 also has a receptacle for the control cam 11', which is also a bore 54. The connection of the control cam 11' and the connecting body 47 relative to the control element 8 can be carried out in a locking manner or by a fixed positive fit or force fit.

[0051] according to Figures 9 to 12 The latch bolts 48, 50 of the locking element 46 are oriented transversely to the movement direction of the transmission rod of the operating mechanism 5 and transversely to the movement direction of the operating transmission rod 7 of the displacement device 1, transversely to the main plane of the leaf 2 in the circumferential direction 6 of the groove at an angle of 90° in the direction away from the leaf 2, through the through hole 70 of the vertical beam 32 of the leaf 2 and perpendicularly to the visible surface of the frame 3, and perpendicularly to the movable direction of the leaf 2 relative to the frame 3. Here, the latch bolts 48, 50 are movably guided in the through hole 70 by the guide sleeve 71.

[0052] In this regard, according to Fig.13 and Fig.14 , the guide sleeve 71 has a hole 72 with an elastic element 73. The elastic element 73 surrounds the outer shell surface of the latching bolts 48, 50 and holds the latching bolts 48, 50 in an adjustable position transversely to the main plane of the leaf 2 and perpendicular to the frame 3 under load. In this case, the latching bolts 48, 50 are in a non-contact position at a predetermined circumferential spacing from the hole 72.

[0053] according to Fig.13 , the elastic element 73 is composed of a plurality of individual segments 74, each of which extends with a free first end 75 toward the center axis 76 of the guide sleeve 71. Here, a ring 77 is formed around the center axis 76 in the hole 72, which is smaller than or at least equal to the outer diameter 78 of the latch bolts 48, 50. The free second ends 79 of the segments 74 are connected in one piece to the hole 72 of the guide sleeve 71.

[0054] according to Figures 9 to 14 In order to easily fit the guide sleeve 71 into the through hole 70 , the outer shell surface 80 of the guide sleeve 71 , which has a circular cross section, is configured to be smaller in diameter than the through hole 70 of the vertical beam 32 .

[0055] In order to define the position of the guide sleeve 71 when it is assembled into the through hole 80, according to Fig.13 On its circular outer surface 80 , the guide sleeve 71 carries at a free first end 81 an annular protruding collar 82 which rests on an outer surface 83 of the vertical beam 32 . Fig.13 and Fig.14 A chamfer 85 is provided at the other free second end 84 of the guide sleeve 71 , which enables alignment of the guide sleeve 71 relative to the through-hole 70 before assembly and thus simplifies squeezing or pressing the guide sleeve 71 into the through-hole 70 .

[0056] In addition, according to Fig.13 and Fig.14 The guide sleeve 71 has a retaining projection 86 arranged on the outer shell surface 80 in the longitudinal direction. The retaining projection 86 can be constructed to be elastic, but when the guide sleeve 71 is pressed into the through hole 70 of the vertical beam 32, at least a clamping effect should be achieved. Figures 11 to 14 In the state in which the guide sleeve 71 is mounted in the through-hole 70, the retaining projection 86 engages in a locking manner from behind a connection strip (not shown) of the profiled leaf 2 of the vertical beam 32, with the flange 82 abutting against the outer surface 83 of the beam 32. The guide sleeve 71 is secured against displacement in the longitudinal direction of the center axis 76. The secured retention is achieved by the sufficient engagement of the retaining projection 86 in the through-hole.

[0057] In terms of material selection, the guide sleeve 71 made of plastic material is not only advantageous in terms of cost, but also has very good sliding properties, is easy to install, and can be manufactured in one piece with the elastic element 73 and the retaining projection 86 .

[0058] In accordance with Figures 5 to 8 In the locked closed position, the locking element 46 is connected in a form-fitting manner to the latching element 24 arranged on the vertical beam of the frame 3.
