Description

[0001] The invention relates to a carriage arrangement for displacing a wing, in particular a sliding wing, a sliding door or a sliding window relative to a frame of the sliding door or a sliding window in a direction transverse, in particular perpendicular, and parallel to the main plane of the sliding door or a sliding window according to the preamble of claim 1.

[0002] Sliding sashes as sliding sashes, or sliding and parallel sliding sashes of a sliding door or sliding window are known in a wide variety of designs and in the simplest case consist of a sash as a sliding sash that is arranged so that it can be moved in an outer frame for opening and closing, and of another door or window element that is also arranged in the frame, for example a passive sash or a fixed field.

[0003] The closed sliding sash can be locked on its outer side of a building, away from the door or window element, by activating an operating mechanism provided in the sliding sash on the frame, 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 pushed in front of an adjacent inactive sash. Parallel stop sashes have a small stop dimension in the open position of the sliding sash to the frame; they are designed solely for free sliding.When closing, the sliding sash is pulled toward the frame, pressing the sliding sash seals back against the frame. Opening and closing can also be controlled via electric, hydraulic, or pneumatic actuators.

[0004] 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.

[0005] The pairs of track 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 run-up profile is adjusted with a wedge surface against a wedge surface of the run-up 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 track roller bearing to the track rollers and from there into the track rail. This torque leads to tilting and jamming of the bolt in the receiving element as well as in the track 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 track rollers.

[0006] Furthermore, WO 2025 / 045421 A1 discloses a carriage assembly for the slidable mounting of a lift-and-slide element, for example a lift-and-slide door or a lift-and-slide window. The carriage assembly can be raised and lowered on a guide rail, wherein the carriage assembly comprises a carriage and a base part attachable to the lift-and-slide element, which base part is coupled to the carriage and has a raised position relative to the carriage and a lowered position relative to the carriage. For a predefined position between the raised and lowered positions, including the raised and lowered positions, a fixation made of a plastic material is effective in the predefined position between the base part and the carriage, which maintains the predefined position. After a first actuation of the lift-and-slide element, the fixation breaks.Reuse of the fixation is no longer possible.

[0007] This assembly guide describes the fixation of a lift-and-slide carriage unit, which uses a locking pin to prevent the carriage from shifting during height adjustment. Operating the fitting releases the locking pin once and cannot be reused.

[0008] Furthermore, reference is made to EP 3078795 B1. The subject matter is a support device for a sliding door, wherein the support device has a carriage for hooking into a guide track and a securing device with a locking element, wherein the locking element prevents the support device or the carriage from being lifted out of the guide track in a securing position, wherein the locking element automatically assumes the securing position after the support device has been hooked into the guide track and / or wherein the locking element is linearly movable or displaceable into or out of the securing position. The support device has a securing element in the form of a cover or cap, which is visible in the installed state and which, in the mounted state, limits movement of the locking element by means of a mechanical blocking.

[0009] The known locking element features movable fixing elements that secure a carriage unit after assembly. However, it does not fulfill the purpose of an assembly aid that locks a carriage unit against possible rotational movement between a support arm and a control plate and is reusable when actuated in the assembled state.

[0010] In principle, it is possible to mount the carriage assembly in the pre-designed groove of the sliding sash and then place the sliding sash onto the frame to ultimately create a sliding connection. In this case, restrictions could arise during the installation of a carriage assembly with a projection device for parallel pivoting on the sliding sash if the projection device of the carriage assembly, which is pivotally mounted on the carriage, is inadvertently adjusted. This increases installation time and makes coupling the functional components more difficult. Incorrect installation could impair the functionality of the sliding door or sliding window and even damage the sliding sash. For optimal operation of the sliding door or sliding window, it must therefore be ensured that the carriage assembly eliminates the aforementioned disadvantages.

[0011] The invention is based on the object of providing a functionally reliable and compact carriage arrangement of a sliding door or a sliding window, 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 sliding door or the sliding window and can be installed and adjusted in a sealing manner in a simple, fast, safe and precise manner with little installation space.

[0012] According to the invention, the object is achieved by the carriage arrangement according to claim 1. Advantageous embodiments of the invention emerge from the features of the subclaims.

[0013] The invention relates to a sliding door or sliding window comprising a fixed leaf or fixed door panel mounted in a fixed frame and additionally equipped with a movable leaf as a sliding leaf. The movable leaf is adjustable relative to the fixed frame and the fixed leaf or door panel from the locked closed position to a parallel, stowed position and can then be moved horizontally from the area of ​​the passage opening of the fixed frame in front of the fixed leaf or fixed door panel.

[0014] To enable these two positions for parallel storage and sliding of the sliding sash relative to the fixed frame and the fixed sash or fixed field, a special fitting arrangement, namely a so-called parallel storage sliding fitting, is provided between the sliding sash and the fixed frame. For operating the sliding door or sliding window, the parallel storage sliding fitting has an operating handle on the sliding sash, an operating mechanism with an operating gear, a displacement device, and a carriage arrangement according to the invention. In addition, a guide rail is attached to the frame on the lower and upper horizontal frame members. For locking, corresponding bolts are arranged on the operating gear of the operating mechanism, which, in conjunction with locking parts arranged on the frame, contribute to the locking.

[0015] The displacement device attached to the sliding sash is connected to pivot points on the frame. With the displacement device engaging the lower and upper horizontal frame members or the cross member, and the coupling connection of the actuating mechanism and the carriage arrangement according to the invention, synchronous movement of the sliding sash for opening and closing on the frame is ensured.

[0016] The displacement device for opening and closing the sliding sash is rotatably displaceable relative to the frame, with the displacement device interacting with the actuating rod and the rod stroke of the actuating mechanism in a movably coupled manner. The actuating mechanism, the displacement device, and the carriage arrangement according to the invention are preferably arranged concealed within the sliding sash in a so-called fitting groove, functionally movable in the circumferential direction of the fold.

[0017] The carriage arrangement according to the invention preferably comprises, in addition to a movable carriage on the guide rail, a deployment mechanism for displacing the sliding sash relative to a frame of the sliding door or sliding window in a direction transverse and perpendicular to the main plane of the sliding door or sliding window. The carriage interacts with the lower guide rail in the lower horizontal frame rail of the fixed frame, displaceable in parallel on the lower horizontal sash member, wherein the carriage consists of a housing with rollers mounted thereon. Upon actuation of the actuating mechanism, the displacement device and the deployment mechanism positively displace the sliding sash into a position parallel to the frame, wherein the sliding sash can then be controlled by the carriage via the guide rail so as to be displaceable freely from the frame.

[0018] Structurally simple and functionally reliable, the opening mechanism comprises a control plate and a support arm rotatably connected to the control plate. The support arm is rotatably connected to the control plate at a first free end. A second free end of the support arm is rotatably or pivotably connected to the housing of the carriage. For simplified and concealed installation of the carriage assembly according to the invention on the lower horizontal sash member of the sliding sash by means of a force-fitting fastening of the control plate, preferably using fastening screws, an assembly aid is provided on the control plate. During the assembly process of the carriage assembly in the sliding sash, the carriage assembly according to the invention remains in a fixed assembly position with the support arm resting on the housing, wherein the support arm and the control plate are inhibited against possible rotation by the assembly aid.

[0019] During the assembly position, the support arm of the carriage arrangement according to the invention is retracted so far that the support arm is covered by the housing in a virtually parallel position, with the sliding sash being spaced apart from one another parallel to the frame. When the carriage arrangement is assembled and the actuating mechanism is coupled, the sliding sash can be moved from the parked assembly position to the frame into a resting and locked closed position. The movement of the sliding sash is achieved by a positively controlled function of the displacement device. During the displacement of the sliding sash from the parked position parallel to the frame towards the resting position to the frame, the assembly aid is automatically adjusted from a fixed mountable position of the carriage arrangement together with the housing against the direction of movement of the sliding sash when the housing is in a resting position against the housing.To achieve this, the support arm of the extension device pivots from its initial position, parallel to the housing—which is the assembly position of the carriage assembly according to the invention—to an angled position relative to the housing. The support arm thereby forms an acute angle to the housing.

[0020] When the sliding sash is positioned parallel to the frame, the sliding sash can be moved parallel to the sliding door or sliding window in an open position, which creates a free passage.

[0021] The assembly aid is advantageously designed as a locking element and is mounted in a guide groove of the control plate so as to be displaceable transversely to the direction of displacement of the carriage arrangement.

[0022] Simple and cost-effective, the locking element is structurally essential and features a stop with a stop surface. When the support arm is in abutting and parallel position with the housing, the locking element is in an active position relative to the housing, with the stop surface resting flat against a flat side of the housing. This represents a non-adjustable passive position for the extension mechanism and the assembly position for the carriage arrangement according to the invention.

[0023] The parallel, parked and movable position of the sliding sash is also the assembly position of the carriage assembly. During the movement of the sliding sash from the parallel, parked and movable position toward the adjacent and / or locked position relative to the frame, the locking element moves automatically or in a forced manner by sliding in the guide groove together with the housing in the opposite direction to the sliding sash's direction away from the frame. The position assumed by the locking element on an outer side of the control plate represents a released and freely movable active position of the deployment mechanism of the carriage assembly from a fixed assembly position by the assembly aid. Preferably, and important for the inventive carriage assembly, the locking element continuously retains its functionality for further fixing of the carriage assembly even when it leaves the fixed position.

[0024] The locking element remains in the guide groove on the outside of the control plate, which has a beneficial effect on the function of the carriage arrangement, as it enables the support arm to adjust the opening mechanism without contact and without resistance.

[0025] For a functional assembly aid of the carriage arrangement, the locking element is simply moved from a passive position into the assembly position with contact with the stop surface on the flat side of the housing during a first assembly or a subsequently recurring assembly in the lower horizontal wing spar, with the locking element seated on the outside of the control plate.

[0026] To ensure the locking element is optimally positioned in the guide groove, especially in the assembly position, and to maintain the position of the rotating control plate and the pivoting support arm of the carriage assembly, the assembly aid features a releasable locking mechanism. The locking element forms a locking connection with the control plate in the assembly position of the assembly aid and in the passive position of the extension mechanism.

[0027] The locking device, with its locking recesses arranged on the outer edges of the locking element, is easy to manufacture, cost-effective, and functionally efficient. When the locking element is moved in the guide groove of the control plate to the assembly position for a passive position of the extension mechanism, the recesses engage with locking projections in the guide rail, thus securing the carriage assembly according to the invention in a fixed position.

[0028] The locking element is simple and cost-effective, made from a spring-elastic band material or plastic. To ensure the assembly aid's full functionality, the locking element is angled at an angle of almost 90° and is divided into two plates with different functions. The first plate forms the stop with the stop surface for the housing, which also serves as a plane for manual actuation. The second plate forms a guide plate, which, adapted to the guide groove of the control plate, enables secure and movable guidance in the guide groove of the assembly aid.

[0029] The locking element, designed as a single unit, ensures secure, horizontal sliding movement within the flat plane of the control plate. While securely preventing vertical displacement relative to the control plate, the guide groove in the control plate is divided into a first level and a stepped second level in cross-section. The locking element and its guide plate are designed to slide and guide according to the stepped cross-section of the guide groove.

[0030] The locking element can be moved in a stable and safe manner in the control plate with the guide plate of the locking element resting on the first level of the guide groove and lateral guidance within the second level into the respective functional positions, such as the assembly position or the passive position, of the carriage arrangement.

They show: Fig. 1 a perspective view of a front view of a sliding door or sliding window in the closed state, shown from the inside of the room, with a sliding sash and an operating mechanism concealed on the sliding sash but visible for identification purposes, with a displacement device for a parallel storage and locking function, a carriage arrangement according to the invention and with a fixed sash on the frame, Fig. 2 an enlarged section after Fig. 1 in a perspective view of the carriage arrangement according to the invention from above in a coupling position with an assembly aid in an active position, the fixed position, for the deployment mechanism of the carriage arrangement, Fig. 3 a perspective view according to Fig. 2 with a control plate of the carriage arrangement and a locking element of the assembly aid, Fig. 4 the carriage arrangement with the assembly aid according to Fig. 2 in a front view, Fig. 5 a side view of the carriage arrangement with the assembly aid according to Fig. 2, Fig. 6 a top view of the carriage arrangement with the assembly aid according to Fig. 2, Fig. 7 a bottom view of the carriage arrangement with the assembly aid according to Fig. 2, Fig. 8 an enlarged section after Fig. 1 in a perspective view of the carriage arrangement according to the invention from below in a coupling position with the assembly aid in an active position to the extension mechanism of the carriage arrangement, Fig. 9 a sectional view through the lower horizontal beam of the sliding door or sliding window according to Fig. 1 with the carriage arrangement according to the invention in a profile groove of the sliding sash positioned parallel to the frame, in a side view in operative connection with a guide rail arranged on the frame and with the assembly aid in an assembly position of the extension mechanism of the carriage arrangement resting against a housing of the carriage, Fig. 10 a sectional view through the lower horizontal beam of the sliding door or sliding window according to Fig. 1 with the carriage arrangement according to the invention in a profile groove of the sliding sash resting on the frame, in a side view in operative connection with a guide rail arranged on the frame and with the assembly aid in a passive position resting on a housing of the carriage with the support arm of the extension mechanism of the carriage arrangement extended, Fig. 11 a sectional view through the lower horizontal beam of the sliding door or sliding window according to Fig. 1 with the carriage arrangement according to the invention in a profile groove of the sliding sash positioned parallel to the frame, in a side view in operative connection with a guide rail arranged on the frame and with the assembly aid in a position away from the housing of the carriage and inoperative with respect to the opening mechanism of the carriage arrangement, Fig. 12 an enlarged section after Fig. 1 in a perspective view of the carriage arrangement according to the invention from above in a coupling position with the assembly aid in a passive position to the extension mechanism, Fig. 13 a perspective view according to Fig. 12 with a control plate of the carriage arrangement and a locking element of the assembly aid, Fig. 14 the carriage arrangement with the assembly aid according to Fig. 12 in a front view, Fig. 15 a side view of the carriage arrangement with the assembly aid according to Fig. 12, Fig. 16 a plan view of the carriage arrangement with the assembly aid according to Fig. 12, Fig. 17 a bottom view of the carriage arrangement with the assembly aid according to Fig. 12 and Fig. 18 an enlarged section after Fig. 12 in perspective view of the carriage arrangement according to the invention from below in a coupling position with the assembly aid in a passive position to the extension mechanism.

[0032] The Fig. Figure 1 shows a front view of a sliding door or sliding window 1, which has a fixedly mounted leaf or a fixed door panel 3 in a fixed frame 2 and which is also equipped with a movable leaf 4 as a sliding leaf. The movable leaf 4 is pivotable relative to the fixed frame 2 and the fixed leaf or door panel 3 from the position shown in the Fig. 1 and Fig. 10 indicated locked closed position into a parallel parked position according Fig. 9 and Fig. 11 and then displaceable from the area of ​​the passage opening of the fixed frame 2 in the horizontal direction in front of the fixed leaf or the fixed door field 3, as can be seen from the Fig. 1 with the indication of the arrow direction 5.

[0033] In order to enable these two positions for parallel parking and sliding of the sliding sash 4 relative to the fixed frame 2 as well as to the fixed sash or the fixed field 3, a special fitting arrangement, namely a so-called parallel parking sliding fitting, is provided between the sliding sash 4 and the fixed frame 2, of which Fig. 1 an actuating handle 6 on the sliding sash 4, an actuating mechanism 7 with an actuating gear and an actuating rod, a displacement device 8 and a Fig. 1 to Fig. 18 has a carriage arrangement 9 according to the invention. In addition, the frame 2 according to Fig. 1, a guide rail 12, 12' is attached to the lower and upper horizontal frame members 10, 11. For locking, corresponding bolts are arranged on the actuating gear of the actuating mechanism 7, which, in conjunction with a locking part arranged on the frame 2, contribute to the locking.

[0034] The displacement device 8 attached to the sliding sash 4 is Fig. 1 is connected to frame-side pivot points. With the engagement of the displacement device 8 on the lower and upper horizontal frame members 10, 11 or on the cross member 13, 14 and the coupling connection of the actuating mechanism 7 and the carriage arrangement 9 according to the invention, a synchronous movement of the sliding sash 4 for engaging and disengaging from the frame 2 is ensured.

[0035] The displacement device 8 for the opening and closing of the sliding sash 4 is rotatably displaceable relative to the frame 2, wherein the displacement device 8 interacts with the stroke of the actuating rod of the actuating mechanism 7 in a movably coupled manner. Fig. 1, the actuating mechanism 7, the displacement device 8 and the carriage arrangement 9 according to the invention are arranged concealed within the sliding sash 4 in a so-called fitting groove 15 in the folding circumferential direction 16 so as to be functionally movable.

[0036] After the Fig. 1 to 18, the carriage assembly 9 according to the invention comprises, in addition to a movable carriage 17 on the guide rail 12, a projection mechanism 18 for displacing the sliding sash 4 relative to a frame 2 of the sliding door 1 or the sliding window in a direction transverse and perpendicular to the main plane of the sliding door 1 or the sliding window. The carriage 17 acts on the lower horizontal sash beam 19 according to Fig. 1, Fig. 9 to Fig. 11 parallel to the lower guide rail 12 in the lower horizontal frame member 10 of the fixed frame 2, wherein the carriage 17 consists of a housing 20 with rollers 21, 21' mounted thereon. The displacement device 8 and the opening mechanism 18 displace the sliding sash 4 upon actuation of the actuating mechanism 7 in a Fig. 10 and Fig. 11 from the frame 2 parallel offset position into a free operating field, wherein the sliding sash 12 can then be controlled by the carriage 17 via the guide rail 12 past the frame 2.

[0037] After the Fig. 2 to Fig. 18, the deployment mechanism 18 has a control plate 22 and a support arm 23 rotatably connected to the control plate 22. The support arm 23 extends according to the Fig. 2, Fig. 7 and Fig. 17 with a first free end 24, a rotatably mounted connection with the control plate 22. With a second free end 25, the support arm 23 is rotatably connected to the housing 20 of the carriage 17. For a simplified and concealed installation of the carriage assembly 9 on the lower horizontal sash member 19 of the sliding sash 4 by means of a force-locking fastening of the control plate 22 with fastening screws (not shown), an assembly aid 26 is provided on the control plate 22, which in the assembly position rests against the housing 20. In the assembly position of the carriage assembly 9, the support arm 23 is located according to the Fig. 2 to 9 in the retracted state, almost parallel to the housing 20 or the carriage 17, which represents the parallel parked position of the sliding sash 4 to the frame 2 in the assembled state. In the assembled state of the carriage arrangement 9 and the coupling connection of the actuating mechanism 7, the sliding sash 4 can be transferred from the parked mounting position to the frame 2 into an adjacent and also locked closed position. The movement of the sliding sash 4 is achieved by a positively controlled function of the displacement device 8. During the displacement of the sliding sash 4 from the parallel parked position to the frame 2 to Fig. 9 in the direction of the adjacent position to the frame 2 after Fig. 10, the mounting aid 26 is automatically adjusted from a fixed mountable position of the carriage assembly 9 together with the housing 20 in the opposite direction to the movement of the sliding sash 2. The support arm 23 of the opening device 18 pivots from its adjacent parallel position to the housing 20 to Fig. 2 to Fig. 9 into an angled position to the housing 20 after Fig. 10 and Fig. 12 to Fig. 18. The angle of the support arm 23 to the housing 20 is an acute angle.

[0038] In parallel position of the sliding sash 4 to the frame 2 after Fig. 9 and Fig. 11, the sliding sash 4 can be moved parallel to the sliding door or sliding window 1 into an open position, which forms a free passage for the sliding door or sliding window 1.

[0039] After the Fig. 2 to Fig. 18, the assembly aid 26 is designed as a locking element 27. From the Fig. 2 to 9 and Fig. 12 to Fig. 18, the locking element 27 is mounted in a guide groove 28 of the control plate 22 so as to be displaceable.

[0040] Furthermore, the locking element 27 points to the Fig. 2 to 9, a stop 29 with a stop surface 30. When the support arm 23 is in a parallel position with respect to the housing 20, the stop surface 30 is in a passive position of the extension mechanism 18 with supporting contact with a flat side 31 of the housing 20 for the assembly position.

[0041] During the movement of the sliding sash 4 from the parallel parked and movable position to Fig. 2 to Fig. 9, which is the assembly position of the carriage assembly 9, in a direction of the adjacent and / or locked position to the frame 2 according to Fig. 10 and Fig. 12 to 18, the locking element 27 adjusts automatically or in a forced manner by sliding in the guide groove 28 together with the housing 20 and in abutting position against the housing 20, away from the frame 2, against the direction of the sliding sash 4. The position assumed by the locking element 27 on an outer side 32 of the control plate 22 represents a released and freely movable active position of the extension mechanism 18 of the carriage arrangement 9 from a fixed mounting position by the mounting aid 26.

[0042] The locking element 27 arranged on an outer side 32 of the control plate 22 according to Fig. 11 to Fig. 18, enables the support arm 23 to be adjusted without contact and without resistance, whereby the locking element 27 in this position can be functionally reused and assumes a waiting position for a possible stop aid.

[0043] For a functional assembly aid 26 of the carriage arrangement 9, the locking element 27 is manually moved in the guide groove 28 into the assembly position with contact with the stop surface 30 on the flat side 31 of the housing 20 during a first assembly or a subsequently recurring assembly in the lower horizontal wing spar 19 from a passive position with the locking element 27 seated on the outer side 32 of the control plate 22 for an assembly position of the carriage arrangement.

[0044] To secure the position of the locking element 27 in the guide groove 28, in particular in the assembly position and to maintain the position of the rotatable control plate 22 and the pivotable support arm 23 of the carriage arrangement 9, the assembly aid 26 has Fig. 3 and Fig. 13 has a locking device 33. The locking element 27 forms a locking connection with the control plate 22 in the assembly position of the assembly aid 26 and in the passive position of the deployment mechanism 18.

[0045] After Fig. 3 and Fig. 13, the locking device 33 has locking recesses 34 on the outer edges of the locking element 27, which, when moved in the guide groove 28 into the assembly position for a passive position of the extension mechanism 18, engage in locking projections 35 and achieve a fixed position of the carriage arrangement 9.

[0046] The locking element 27 is manufactured simply and cost-effectively from a spring-elastic band material or from a plastic. For the complete functionality of the assembly aid 26, the locking element 27 is Fig. 3 and Fig. 13 is angled at an angle 37 by almost 90° and is divided into two differently functional plates, whereby the first plate forms the stop 29 with the stop surface 30 for the housing 20, which is also used as a plane for manual actuation, and the second plate forms a guide plate 36, which, adapted to the guide groove 28 of the control plate 22, enables a secured and displaceable guide in the guide groove 28 of the assembly aid 26.

[0047] For horizontal displacement of the locking element 27 within the flat plane of the control plate 22 with secure hold against vertical adjustment to the control plate 22, the guide groove 28 in the control plate 22 is divided in cross section into a first plane 38 and a second plane 39, wherein the locking element 27 with its guide plate 36 is designed to be displaceably guided and adapted to the stepped cross section of the guide groove 28.

[0048] Stable and safely guided, the locking element 27 is guided in the control plate 22 according to the Fig. 2 to Fig. 18 with support of the guide plate 36 of the locking element 27 on the first level 38 of the guide groove 28 and lateral guidance within the second level 39.
