Relocation device for the forced relocation of a sash, in particular a sliding sash, a window or a door

Description

[0001] The invention relates to a displacement device for the forced displacement of a sash, in particular a sliding sash, 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.

[0002] 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 in an outer frame to be slidable for opening and closing, and of another door or window element, for example a fixed sash or fixed panel, also arranged in the frame.

[0003] 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 integrated into the sash, thus preventing unauthorized opening. Horizontally movable sliding sashes with a parallel stop mechanism are usually mounted above or below the sash so that they slide smoothly. When opened, typically using an operating handle on the sash, the sash is stopped perpendicular to the main plane of the frame, with the seals aligned, allowing it to slide more easily. The opened sliding sash can then be slid in front of an adjacent fixed sash. Parallel stop sashes with a small stop distance to the frame when open are designed solely for free sliding. When closing, the sliding sash is pulled towards the frame, pressing the sash seals against the frame again.Opening and closing is also possible via electric, hydraulic or pneumatic actuators.

[0004] A device is known from DE 7127697 U. The offset movement, perpendicular to the plane of the sliding sash frame, enables a seal between the sliding sash and the frame. This is achieved using pairs of rollers held by a roller bearing, which are slidably mounted on a bolt attached to the sliding sash frame. A slidably mounted strip, carrying a guide profile, is also incorporated in the sliding sash. When the strip is moved, the entire sliding sash shifts against a fixed guide element due to the engagement of the guide profile, causing the bolt to penetrate the guide element and compressing the spring. When the strip is moved back, the spring relaxes, returning the sliding sash to its initial position.

[0005] The roller pairs have a narrow central section on the sliding sash bolt. To move the sliding sash perpendicular to the frame, the guide profile engages with a wedge-shaped surface against a wedge-shaped surface of the guide element. This design has the disadvantage that, due to the asymmetrical force application, a torque is introduced into the bolt. This torque is then transmitted from the bolt, via a narrow section of the roller bearing, into the rollers and from there into the track. This torque causes the bolt to tilt and jam in both the mounting element and the roller bearing, resulting in stiff operation of the described design. The present design is structurally complex, requires space, and is not suitable for providing a cost-effective solution when dealing with high loads requiring more than two roller pairs.

[0006] EP 0600102 A1 discloses a fitting for forcibly locking a wing into the tilt or sliding position.

[0007] German patent DE 102016119515 A1 discloses a sliding door unit comprising a frame and a sliding door that can be moved within the frame, in which at least one fitting is installed. Several locking bolts are provided along the height of a frame profile of the frame, which can engage with a corresponding locking element. Alternatively, several locking bolts can also be provided along the height of a frame profile of the sliding door, each of which engages with a locking housing on the frame. In one embodiment, a locking element is provided that prevents the sliding door lock from being actuated when the locking bolt is in a retracted position. The sliding door locks when the locking bolt is in the extended position and can engage with the locking element.The locking element can engage 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 only fully movable when the locking bolt is in the extended position.

[0008] Furthermore, EP 2778329 B1 discloses a multi-part locking piece comprising 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 towards the slot-like receptacle.

[0009] The design with a slot-like recess is complex to manufacture and therefore expensive. A disadvantage of this design is that tolerances in the fitting can cause the locking piece to tilt and jam, which can render the aforementioned construction difficult to operate or even unusable.

[0010] EP 1580362 B1 discloses a sliding door, a sliding window with a sliding panel and with a lateral boundary located in the opening direction of the sliding panel, along which the sliding panel is slidable in the opening and closing directions and with which the sliding panel overlaps in the sliding direction, wherein the sliding panel can be locked and unlocked by means of at least one controllable locking mechanism, which is provided between the sliding panel and the lateral boundary in the area of ​​the overlap and comprises locking elements on both sides, which can be moved relative to each other transversely to the main plane of the sliding panel into a locking state, in which they overlap each other transversely to the main plane of the sliding panel and block the sliding panel against movement in the sliding direction, or into an unlocking state by means of at least one push rod arrangement movable parallel to the main plane of the sliding panel.in which they release the sliding panel for movement in the sliding direction, wherein at least between a push rod arrangement and one of the cooperating locking elements a deflection gear is provided, by means of which movements of the push rod arrangement parallel to the main plane of the sliding panel can be converted into movements of the associated locking element transverse to the main plane of the sliding panel. A locking bolt is guided slidably in a guide sleeve on the sliding panel side transversely to the main plane of the sliding panel.

[0011] Furthermore, reference is made to DE 2331735 A1, which describes a device for at least gas-tight locking of gate leaves to circumferentially bounding frames. After being inserted into the passageway or opening, the gate leaves can be pressed against elastically compliant sealing elements attached to the frames by means of metallic edgings by means of several locking mechanisms of essentially identical design, each with a closed metallic sealing strip facing the sealing plane and arranged circumferentially. For this purpose, the bolts are arranged in the free end section and have a turned pin that is encompassed by one end section of the helical compression spring, while the opposite end section of the helical compression spring is supported in a cylindrical bushing, which is inserted into recesses in the upward-facing inner leg of the lower double-T profile.the downward-pointing inner leg of the upper double-T profile is attached. Both end sections of the helical compression spring are thus sufficiently supported in the transverse direction, preventing it from breaking out of the axial spring direction.

[0012] The locking bolt requires a precise fit to engage the bolt. Minimal deviations can cause the locking bolt to tilt or jam, preventing secure locking.

[0013] The invention is based on the objective of providing a reliable and compact relocation device with a locking device for a window or door, in particular a sliding sash as a parallel-tilt sliding sash, which eliminates the aforementioned disadvantages, is cost-effective with good aesthetics for the window or door, and can be mounted, adjusted and locked in a simple, quick, safe and precise manner with little installation space.

[0014] According to the invention, the problem is solved by the displacement device with a locking device according to claim 1. Advantageous embodiments of the invention are described in the features of the dependent claims.

[0015] The essential feature here is that the displacement device can be functionally mounted in the circumferential direction of the rebate on both the horizontal and vertical stiles of the sash. The displacement device, when positioned on the horizontal sash, forcibly moves the sash vertically into a closed position away from the frame into a free operating area and guides the sash against the frame during a sliding 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 side of the actuating handle controlled by the actuating mechanism. It can be controlled by a locking element located on the vertical frame into a locked closed position or an unlocked and sliding open position.

[0016] The locking element comprises a locking bolt that extends transversely through a through-hole in the vertical frame, perpendicular to the main plane of the wing, and is guided longitudinally relative to the central axis by a guide sleeve located in the through-hole. Preferably, an elastic element is arranged in a bore of the guide sleeve. The bore has a larger cross-section than the bolt. The elastic element grips the locking bolt within the bore, thus compensating for the difference in cross-section between the bolt and the bore, and holds the locking bolt in a slidable position at a predetermined distance from the inner surface of the guide sleeve. Due to the elasticity of the element, the locking bolt is guided by a spring force around the elastic element, allowing it to slide longitudinally relative to the central axis of the guide sleeve.Furthermore, the locking bolt has freedom of movement within the bore of the guide sleeve up to the inner wall of the bore. Any resulting dimensional deviations and tolerances are automatically compensated for by the resulting clearance within the bore for the locking bolt. Locking and unlocking the locking bolt in the locking element mounted on the frame is achieved without any jamming or stiffness, thanks to the 360° freedom of movement around the central axis of the locking bolt.

[0017] For a consistently seated locking bolt in the bore of the guide sleeve, the elastic element according to the invention consists of several individual segments, each extending with a free first end towards the central axis of the guide sleeve, wherein the segments preferably form a ring around the central axis of the bore, which is smaller than or at least corresponds to the circular cross-section of the locking bolt, and wherein the respective second free ends of the segments are integrally connected to the bore of the guide sleeve and form an integral component with the guide sleeve.

[0018] To facilitate easy installation of the guide sleeve into the through-hole on the vertical spar, the circular outer surface of the guide sleeve is designed with a diameter smaller than that of the through-hole of the vertical spar.

[0019] In an advantageous embodiment, the guide sleeve is secured in the through-hole by a collar projecting annularly at the free end of the circular outer surface of the guide sleeve, which abuts an outer surface of the vertical stile after complete assembly. Apart from the collar, the guide sleeve sits within the through-hole of the vertical stile. Preferably, the guide sleeve extends through the entire cross-section of the through-hole, so that the locking bolt can be controlled by the guide sleeve within the cross-section of the vertical stile.

[0020] A further advantage for simple and cost-effective installation is the chamfer or radius at the second free end of the guide sleeve. The chamfer allows the guide sleeve to be adjusted to the through-hole and then inserted into it.

[0021] The guide sleeve is preferably made of a plastic material due to its good sliding properties and cost-effective manufacturing, enabling a spring-like effect to be implemented within the guide sleeve. However, other materials are also possible.

[0022] To ensure the guide sleeve is securely held in the through-hole, retaining projections are provided at intervals on the outer surface of the guide sleeve. These projections extend convexly along the length of the guide sleeve and clamp it in the through-hole of the vertical spar. Alternatively, rings with a hook-like free end, also convex to the outer surface, can be used. For secure retention of the guide sleeve in the installed state, the retaining projections engage a web of the profiled wing in a snap-fit ​​manner. Another option for securely fastening the guide sleeve in the through-hole of the wing is to clamp the retaining projections to the walls of the through-hole.

[0023] Further advantageous designs can be seen in the drawings. They show: Fig. 1 is a perspective view of a front view of a window or door in the closed position, shown from the inside of the room, with a sliding sash and an operating mechanism concealed on the sliding sash but shown visible for identification, with a displacement device for a parallel locking and resting function and with a fixed sash attached to the frame.

Fig. 11 and Fig. 12 and Fig. 14 a perspective view from the rear of a guide sleeve according to the invention Fig. 11 and Fig. 12 .

[0024] The Fig. 1The drawing shows a front view of a window or door 4, which has a fixed sash or door panel 39 mounted in a fixed frame 3 and is also equipped with a movable sash 2. The movable sash 2 is positioned relative to the fixed frame 3 and the fixed sash or door panel 39 from the side shown in the drawing. Figs. 1 to 8 from the indicated locked closed position adjustable into a parallel, unlatched position and then slidable horizontally from the area of ​​the passage opening of the fixed frame 3 in front of the fixedly installed sash or the fixed door panel 39, as shown in the Fig. 1 as can be seen with the arrow direction indicator 22.

[0025] In order to enable these two positions for parallel positioning and sliding of the sash 2 relative to the fixed frame 3 and to the fixed sash or the fixed panel 39, a special fitting arrangement, namely a so-called parallel positioning sliding fitting, is provided between the sash 2 and the fixed frame 3, from which the Fig. 1 and Fig. 2 an actuating handle 40 on the sliding wing 2, an actuating mechanism 5 with an actuating gear, the displacement device 1 according to the invention, and in Fig. 2 a locking device 41, 42 and the running element 23. Furthermore, the frame 3 is fitted with Fig. 1A guide rail 21 is attached to the lower and upper horizontal frame members 43, 44. A locking device 41 with bolts on the actuating gear of the actuating mechanism 5, in conjunction with a strike plate arranged on the frame 3, contributes to locking and promotes the longitudinal and lateral movement of the sliding sash 2, optionally in conjunction with the actuating mechanism 5 by means of beveled bolts and strike plates on the frame 3.

[0026] The relocation device 1 indicates Figs. 3 to 8A control element 8 is provided, which consists of a control tab 9 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. Furthermore, the displacement device 1 is identical on the respective lower and upper horizontal rails 29, 30 of the movable wing 2. The displacement device 1 must be designed so that its frame-side pivot points, formed by the control cam 11, 11', engage the horizontal guide rail 21 in the lower and upper horizontal frame rails or crossbeams 43, 44 of the fixed frame 3. Fig. 1 can constantly intervene and a synchronous movement of its control element 8 arranged for display is ensured.

[0027] The rotatable displacement of the control tab 9 is effected by a control contour 12 arranged on the control tab 9. Fig. 3This enables the control bolt 13, which is coupled to the actuating linkage 7 of the displacement device 1 and to the linkage of the actuating mechanism 5, to interact with the control bolt 13. The control bolt 13 is preferably designed as a mushroom bolt and passes through the control contour or recess 12 of the control tab 9, which is arranged longitudinally to the movable actuating linkage 7, during the stroke of the actuating mechanism 5. The control contour 12 and the control bolt 13 are coordinated such that, when the control bolt 13 moves, the control tab 9 can pivot transversely to the circumferential direction 6 of the fold at the fixed pivot point 16 located on the cover rail 15 at the second free end 14. The pivot point 16 is designed as a mushroom bolt, and the control bolt 13 is designed as follows: Fig. 3 , the control tab 9 is held securely in a fixed position so that it can rotate freely.

[0028] In Fig. 4To reduce frictional resistance and running noise, a movable roller or sliding bushing 36 is arranged between the control bolt 13 and the control contour 12, which is movably mounted on the control bolt 13.

[0029] For the forced control of the control element 8 arranged on the displacement device 1, the control tab 9 forms a connecting element from the sash 2 to the frame 3. With the forced transmission of the control tab 9 from the sash 2 to the frame 3 and with the displacement of the sash 2 from a locked closed position and retracted position of the displacement device 1 perpendicularly in the direction of a free actuation field from the sash 2 to the frame 3 and conversely from a parallel 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 is Fig. 3 , Figs. 5 to 8completely enclosed and forms a securely sliding closed guide for the control bolt 13. After Fig. 3 and Fig. 5Coupling elements 19, 20 are formed at the free ends 17, 18 of the actuating linkage 7 of the displacement device 1, which form a coupling connection with the linkage of the actuating mechanism 5, partially or fully around the wing 2 and the frame 3, wherein with horizontal arrangement of the displacement device 1 on the wing 2 the control cam 11 is pivotably and slidably 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 stile 32 of the sash 2, is operatively locked to a locking element 24 arranged on the vertical stile of the frame 3 in the closed position of the sash 2 to the frame 3, and with a forced displacement of the sash 2 to the frame 3 into a parallel position, the locking element 46 can be released from the locking element 24.

[0030] The displacement device 1 and the actuating mechanism 5 are concealed within a standardized profile groove 26 of the sash 2 in the area of ​​a rebate 25 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 designed with a width 27 adapted to a conventional profile groove 26 and are dimensionally no larger than 18 mm, with the control tab 9 having a width 28 Fig. 3 in its longitudinal extension to the fold circumference direction 6, it is slightly wider.

[0031] 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 beyond the profile groove 26 in the direction of frame 3.

[0032] On the lower horizontal wing spar 29 after Fig. 1, at least one running element 23 is arranged for parallel displacement, which is designed to safely support the weight of the movable wing 2 while cooperating with a lower running rail 21 in the lower horizontal frame member 43 of the fixed frame 3.

[0033] The control cam 11 and the running element 23 are guided on a web (not shown) of the track 21 and are arranged transversely to the direction of travel of the sash 2, offset from each other. The control cam 11 and the running element 23 are each secured against falling out of the track 21 by means of parallel guides running through a groove (not shown) and the web on the track 21, and are guided in a controllable manner on the track 21. A roller or sliding bushing 31 is rotatably mounted on the control cam 11. To improve the guidance of the running element 23, the web is rounded at its free end. The web and a web 35 visible from the inside of the building together form the groove-shaped guide for the control cam 11.

[0034] The displacement device 1, attached to the sash 2 and movably connected to the frame 3 in the track 21, and the running element 23, attached to the sash 2 and slidable in the track 21 on the frame 3, connect the slidable sash 2 to the frame 3. For this purpose, the displacement device 1 is attached to the lower and upper horizontal stiles 29, 30 of the sash 2 according to Fig. 1 arranged and includes according Fig. 3 The control element 8, which, upon actuation of the actuating handle 40, is coupled to the movable linkage of the actuating mechanism 5 with the actuating gear, forcibly moves the sash 2 from a locked closed position into a position perpendicular to the frame 3 and movable for parallel movement of the sash 2 along the frame 3. Independently of the displacement device 1 and the actuating mechanism 5, the running element 23 is Fig. 1The sash 2 is automatically moved into a freely movable position by means of a parking mechanism (not shown) arranged on the running element 23, with rollers 45, and can be moved via the running rail 21. Due to their separate construction from the running element 23, the control elements 8 and the guide elements with the control cam 11 of the displacement device 1 require no structural measures for load transfer. During the pivoting movement of the control tab 9 from pivot point 16 to the control cam 11, 11', an angle results that determines the distance between the sash 2 and the frame 3 from the closed position to the parallel position of the sash 2 relative to the frame 3. The distance obtained from this angle allows the sash 2 to move without contact against the frame 3 in the directions of arrow 22. Fig. 1 to be moved past each other.

[0035] With the installation of the relocation device 1 after Fig. 1on the vertical spar 32 of the wing 2 and adapting a locking element 46 to Figures 5 to 8 The displacement device 1, together with a locking element 24 arranged on the vertical beam of the frame 3, forms a locking device 42 on the opposite side to the locking side of the locking device 41 of the actuating gear with the locking element arranged there. Further to Fig. 5 and Fig. 7 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, by being plugged in or snapped into place. The locking element 46 consists of a connecting piece 47 and optionally of a locking bolt 48 with a mushroom-shaped bolt forming a plate 49, or a locking bolt, also referred to as a pin 50, as shown in the Figures 5 and 7 is shown.

[0036] It also proves cost-effective that the locking element 24, depending on the design of the locking element 46, has different locking engagements 51, 52, either with the locking bolt 48 and the plate 49 forming mushroom bolts or with the locking bolt 50 in a mirror-rotated configuration. Thus, locking engagement 51 has a recess on one side of the locking element 24 for lateral engagement of the plate 49 with the locking bolt 48, and locking engagement 52 has a bore for vertical engagement of the locking bolt 50. The locking element 24 consists of a housing 55, which comprises a base plate 58 and a hollow body 59 attached to it. The housing 55 and the base plate 58 together form a single-piece assembly.

[0037] The connecting piece 47 securely receives the locking bolt 48, 50, in this embodiment within a bore 53. Furthermore, the connecting piece 47 (not shown) features a lock nut in a press fit; in this embodiment, a lock nut M8 according to DIN 985. The locking bolt 48, 50 is screwed into the internal thread of the lock nut via a thread (not shown). The connection between the locking bolt 48, 50 and the lock nut allows the locking element 46 to be adjusted relative to the locking element 24, while simultaneously ensuring the locking bolt 48, 50 is held securely in position by the anti-rotation feature in the lock nut. The connecting piece 47 also has a receptacle, likewise a bore 54, for the control cam 11'. The connection between the control cam 11' to the control element 8 and the connecting piece 47 can be detented or secured by a positive or non-positive fit.

[0038] After Figs. 9 to 12The locking bolt 48, 50 of the locking element 46 is aligned transversely to the direction of movement of the linkage of the actuating mechanism 5 and the actuating linkage 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 away from the sash 2 through a through-hole 70 of the vertical mullion 32 of the sash 2, perpendicular to the visible surface of the frame 3 and perpendicular to the stopable movement of the sash 2 towards the frame 3. The locking bolt 48, 50 is slidably guided within the through-hole 70 by a guide sleeve 71.

[0039] The guide sleeve 71 demonstrates this. Figs. 13 and 14A bore 72 with an elastic element 73. The elastic element 73 encompasses the outer surface of the locking bolt 48, 50 and holds the locking bolt 48, 50 under force in a position adjustable transversely to the main plane of the sash 2 and perpendicular to the frame 3. The locking bolt 48, 50 is in a non-contact position at a predetermined distance from the bore 72.

[0040] The elastic element 73 consists of Fig. 13 The guide sleeve 71 consists of several individual segments 74, each extending with a free first end 75 towards the central axis 76 of the guide sleeve 71. A ring 77 is formed around the central axis 76 in the bore 72, the ring being smaller than or at least equal to the outer diameter 78 of the locking bolt 48, 50. The respective second free ends 79 of the segments 74 are integrally connected to the bore 72 of the guide sleeve 71.

[0041] For easy assembly of the guide sleeve 71 according to Figs. 9 to 14 into the through-bore 70, the circular cross-sectional surface 80 of the guide sleeve 71 is formed with a diameter smaller than that of the through-bore 70 of the vertical spar 32.

[0042] To limit the position during the installation of the guide sleeve 71 in the through-hole 70, the guide sleeve 71 has a first free end 81 on its circular outer surface 80. Fig. 13 a ring-shaped protruding collar 82, which comes into contact with an outer surface 83 of the vertical spar 32. At the other second free end 84 of the guide sleeve 71 Figs. 13 and 14 , a chamfer 85 is arranged which allows the guide sleeve 71 to be adjusted to the through bore 70 before assembly, thus facilitating the pressing or insertion of the guide sleeve 71 into the through bore 70.

[0043] Furthermore, the guide sleeve 71 shows Figs. 13 and 14Retaining projections 86 are provided on the cylindrical surface 80 in the longitudinal direction. The retaining projections 86 can be elastically designed, but should at least achieve a clamping effect when the guide sleeve 71 is pressed into the through-hole 70 of the vertical spar 32. In the installed state of the guide sleeve 71 in the through-hole 70, Figs. 11 to 14 The retaining projections 86 engage behind a web (not shown) of a profiled wing 2 of the vertical spar 32, with the collar 82 abutting the outer surface 83 of the spar 32. The guide sleeve 71 is secured against displacement in the longitudinal direction of the central axis 76. A secure hold is also achieved by sufficient clamping of the retaining projections 86 in the through-hole 70.

[0044] Choosing to manufacture the guide sleeve 71 from a plastic material offers not only cost advantages. The guide sleeve 71 also exhibits very good sliding properties, is easy to assemble, and can be manufactured as a single piece with the elastic element 73 and the retaining projections 86.

[0045] In locked position after Figs. 5 to 8 The locking element 46 is positively connected to the locking element 24 arranged on the vertical stile of the frame 3. In the position of the sash 2 parallel to the frame 3 (not shown), the locking bolt 48, in conjunction with the plate 49 (collectively referred to as a mushroom bolt), remains engaged with the locking element 24, while the locking bolt 50 is in a disengaged position. By sliding in the direction of arrow 22 to Fig. 1When the wing 2 is moved against the frame 3 in the direction of the open position for free passage through the window or door 4, the locking position of the mushroom bolt 48, 49 between the locking element 24 is also released when the wing is in a vertical position, so that the mushroom bolt 48, 49 as well as the locking bolt 50 are in a free operating field.
