Description

[0001] Sliding door and method for closing a sliding leaf of a sliding door arranged to be movable in a frame

[0002] The present invention relates to a sliding door with a frame and at least one sliding leaf which can be moved in the frame and which can be moved between a closed position and a parallel stored position via a control device and can be moved along a guide rail in the parallel stored position, and to a method for closing a sliding leaf of a sliding door which is arranged to be movable in a frame.

[0003] EP 3 859 110 B1 discloses a sliding door fitting comprising two carriages movable on a guide rail for supporting the sliding sash, each carriage comprising a roller part and a support part movable relative to the roller part. As a result, the sliding sash can be moved from a closed position into a parallel stored position via a control device by moving a drive rod of the control device so that several control elements are each moved along a curved guide so that the sliding sash can then be moved into the parallel stored position without dragging. In order to securely lock the sliding sash in the closed position, it must be moved into an end position along the guide rail in the frame so that corresponding locking elements can ensure reliable locking. This requires a certain amount of force, especially with heavy sliding sashes.

[0004] It is therefore an object of the present invention to provide a sliding door and a method for closing a sliding leaf of a sliding door which is arranged to be movable in a frame, in which handling is improved.

[0005] This object is achieved with a sliding door having the features of claim 1 and a method having the features of claim 12.

[0006] A sliding door according to the invention comprises a frame and at least one sliding sash which can be moved in the frame and which can be moved between a closed position and a parallel stored position via a control device and can be moved along a guide rail in the parallel stored position. Between the frame and the sliding sash, a self-closing mechanism is provided to hold the sliding sash in the parallel stored position. The self-closing mechanism has a housing and a driver which can be moved along a guide track on the housing and is pre-tensioned into an end position by an energy accumulator and can be coupled to an activator. The self-closing mechanism can therefore pull the sliding sash from an open position to the end position, in which the sliding sash can then be moved from the parallel stored position to the closed position, i.e. perpendicular to the direction of travel of the sliding sash along the guide rail.The self-closing mechanism ensures that the sliding sash is in its final position when closed, before moving perpendicularly from its parallel position into the closed position. This reliably locks the sliding sash and prevents it from moving toward the frame shortly before it reaches the closing position. In addition, the self-closing mechanism reduces the energy required to close the sliding sash, preventing the sliding sash, with its heavy weight, from colliding with the frame at excessive speed, thus reducing the risk of damage.

[0007] Preferably, the driver of the self-closing mechanism is movable along the guide track parallel to the direction of travel of the sliding sash. The driver is then held displaceably relative to the activator in a direction perpendicular to the plane of the sliding sash in the end position of the sliding sash. This allows the activator to remain engaged with the driver, regardless of whether the sliding sash is in the closed position or the parallel parked position. For this purpose, the activator and the driver, in the coupled position, have sufficient overlap in a direction perpendicular to the plane of the sliding sash.

[0008] The travel distance of the sliding sash from the closed position to the parallel-parked position is preferably between 4 mm and 40 mm, in particular between 6 mm and 30 mm. Throughout this travel distance, the activator and driver remain engaged even during movement perpendicular to the plane of the sliding sash between the closed position and the parallel-parked position.

[0009] For effective installation, the activator is fixed to the frame and the self-closing mechanism is held to the sliding sash. For this purpose, the housing of the self-closing mechanism can be arranged in a groove-shaped recess in the sliding sash. The housing of the self-closing mechanism can be at least partially supported laterally to prevent bending even under high loads. Alternatively, it is of course also possible to install the self-closing mechanism on the frame and the activator on the sliding sash. To ensure that the sliding sash can be moved safely into its end position even under high weight loads, the energy storage device is preferably designed as a gas spring. Different gas springs can be used for different weight loads caused by sliding sashes of different sizes.

[0010] In the closed position, the sliding sash preferably rests against the frame via at least one seal. The seal can be provided all the way around, i.e., in a frame-like manner, to ensure a reliable seal between the sliding sash and frame. For optimized thermal insulation, at least two or more seals can be provided at different levels between the sliding sash and frame. In the parallel position, a gap is then provided between the frame and the sliding sash, allowing the sliding sash to be moved without rubbing against the seals.

[0011] To ensure a stable self-closing mechanism, the housing comprises two plates, particularly made of metal or plastic, between which the driver is guided. The energy storage device, particularly the gas spring, can also be arranged between the plates.

[0012] The control device for moving the sliding sash preferably comprises a drive rod fitting with a plurality of control elements, each of which can be moved in a curved guide to move the sliding sash between the closed position and the parallel, parked position. Drive rods of the drive rod fitting can be provided on several sides of the sliding sash, which are coupled via the control elements to corresponding curved guides on the frame or a central joint profile in the frame. The control device for the sliding door fitting can be designed as disclosed in EP 3 859 110 B1. A carriage for supporting the sliding sash can be designed, for example, according to EP 3 321 459 B1.

[0013] In a further embodiment, the self-closing mechanism can comprise a damper, by means of which the movement of the sliding sash from an opening position to the parallel, parked end position can be slowed down. Linear dampers, in particular fluid dampers, can be used as dampers, for example. For a compact design, the self-closing mechanism is preferably arranged between an upper frame profile of the sliding sash and an upper frame profile of the frame. The position of the self-closing mechanism can be arranged closer to the opening side than to the closing side in a plan view of the sliding sash.

[0014] In the method according to the invention for closing a sliding sash of a sliding door arranged to be movable within a frame, the sliding sash is moved from an open position into the closing direction. An activator is coupled to a driver of a self-closing mechanism. This driver is moved along a guide track by an energy accumulator and moves the sliding sash into an end position along the track, in which the sliding sash is positioned parallel to the frame. From this parallel position, the sliding sash is moved into a closed position by a control device, with the activator simultaneously being moved relative to the driver.This ensures that the sliding sash is moved to a final position along the track rail via the self-closing mechanism before the sliding sash is moved perpendicular to the plane of the sliding sash from the parallel position to the closed position via the control device. This ensures reliable locking of the sliding sash and easy handling. It also prevents damage that could otherwise occur due to excessive energy input from the sliding sash into the frame. Furthermore, locking in the wrong position, i.e., not in the final position, is prevented.

[0015] The invention will be explained in more detail below using an exemplary embodiment with reference to the accompanying drawings. They show:

[0020] Sliding sash in the area of ​​a self-closing mechanism; Figures 4A to 4C show several partially sectioned views of the sliding sash with different positions of the self-closing mechanism;

[0021] Figures 5A and 5B show two sectional views through the sliding door in a parallel parked position and a closed position;

[0022] Figure 6 is a perspective view of the self-retracting mechanism, and

[0023] Figure 7 is an exploded view of the self-retraction of the figure

[0024] 6.

[0025] A sliding door 1 comprises a frame 2 in which a sliding sash 3 is arranged. The sliding sash 3 can be moved parallel from the illustrated closed position in a first step as indicated by the arrow, i.e. perpendicular to the plane of the sliding sash 3, and can then be moved from the parallel position along a floor-side guide rail 6 in the opening direction. The sliding sash 3 is arranged in a closed position next to a vertical profile 4 of the frame 2. A vertical center butt profile 5 is located in a central area of ​​the frame 2. In addition to the center butt profile 5, on the side facing away from the sliding sash 3, optionally at least one fixed field with a stationary filling element or at least one further sliding sash is provided. The fittings on the sliding sash 3 can be designed as shown in EP 3 859 110 B1.

[0026] Figure 2 shows a section through the vertical profile 4 of the frame 2 and a profile of the sliding sash 3 in the area of ​​a handle element 30. The handle element 30 can move a drive rod fitting 11 by turning a polygon 7, the drive rod fitting 11 being arranged circumferentially on the sliding sash 3. The sliding sash 3 is U-shaped on the side facing the vertical profile 4 and engages around a projection of the vertical profile 4 with two webs 9. On one side, a seal 8 is held on a web 9 and rests against the projection. The opposite web 9 rests against another seal 8, which is held on a web of the vertical profile 4, so that the sliding sash 3 is sealed by the seals 8 across at least two sealing levels.By turning the handle element 30, the sliding sash 3 in Figure 2 can be moved slightly in the horizontal direction, so that the seals 8 are released and the sliding sash 3 can then be moved along the guide rail 6.

[0027] Figure 3 shows a self-closing mechanism 13 arranged between the sliding sash 3 and the frame 2. The self-closing mechanism 13 is arranged between an upper frame profile of the sliding sash 3 and an upper frame profile of the frame 2. The self-closing mechanism 13 comprises a housing 14 which is fixed to the sliding sash 3 and forms a guide track 16 for a driver 15. The guide track 16 is formed by a slot, but can also be formed by a groove or guide webs on a housing. The guide track 16 comprises an angled end section 17 at one end, on which the driver 15 can be parked. The driver 15 is guided along the guide track 16 by two pins 18 on opposite sides.

[0028] The driver 15 is coupled to an activator 12, which is fixed to the frame 2 and thus arranged in a stationary manner. In an alternative embodiment, the self-closing mechanism 13 can also be mounted on the frame 2 and the activator 12 on the sliding sash 3.

[0029] The self-retracting mechanism 13 comprises a force accumulator 19 in the form of a gas spring, which is mounted on the housing 14 and connected to the driver 15 via a connecting part 20. As a result, the driver 15 is preloaded toward the illustrated end position on the linear section of the guide track 16, with the gas spring being tensioned when the driver 15 moves toward the angled end section 17.

[0030] The housing 14 engages over a holder 21 having an upwardly projecting projection 22. The holder 21 is fixed to the sliding sash 3.

[0031] The function of the self-retractor 13 is shown in Figures 4A to 4C.

[0032] In Figure 4A, the sliding sash 3 is in an open position and has been moved along the guide rail 6 in the opening direction. To close the sliding door 1, the sliding sash 3 is moved in the closing direction, so that the self-closing mechanism 13 with the housing 14 moves close to the activator 12 on the frame 2. The driver 15 is parked at the angled end section 17 of the guide track 16, and the energy accumulator 19 is tensioned.

[0033] Figure 4B shows the coupling of the activator 12 to the driver 15. As the sliding leaf 3 moves in the closing direction, the activator 12 engages a receptacle of the driver 15, pivoting the driver 15 and moving the pin 18 out of the angled end section 17. This allows the energy accumulator 19 to act on the driver 15 and move it along the linear section of the guide track 16.

[0034] The driver 15 is moved by the energy accumulator 19 to an end position shown in Figure 4C. In this position, the sliding sash 3 is located on the vertical profile 4 and thus closes the opening within the frame 2, but is still in the parallel, parked position. From this position, the sliding sash 3 can also be moved again in the opening direction, whereby at the beginning of the opening process the driver 15 is moved along the guide track 16 to the angled end section 17 and in the process tensions the energy accumulator 19. Upon reaching the angled end section, the driver 15 pivots and decouples the activator 12 from the driver 15, so that the sliding sash 3 can be moved freely.

[0035] Figure 5A shows a sectional view through the upper frame profile of the outer frame 2 and the upper frame profile of the sliding sash 3, with the sliding sash 3 in the parallel stowed position. The activator 12 is engaged with the driver 15. It can be seen that the housing 14 of the self-closing mechanism 13 is arranged in a groove-shaped receptacle of the sliding sash 3. The housing 14 rests on the frame profile of the sliding sash 3 on two sides. The groove-shaped receptacle on the sliding sash 3 is wider than the housing 14. In the parallel stowed position, a gap is provided between the seals 8 and the sliding sash 3 or the outer frame 2.

[0036] In Figure 5B, the sliding sash 3 has been moved into the closed position via the control device. In doing so, the sliding sash 3 has been moved to the left compared to Figure 5A, with the activator 12 being displaced relative to the driver 15. However, the overlap of the activator 12 with the driver 15 is so large that even in the closed position, there is engagement between the activator 12 and the driver 15. In the closed position, the sliding sash 3 rests against the frame 2 via at least one seal 8; in the illustrated embodiment, three sealing levels are provided by different seals 8.

[0037] The self-closing mechanism 13 is shown in detail in Figures 6 and 7. The self-closing mechanism 13 comprises a housing 14 with two plates 14a and 14b, preferably made of metal, for example a steel sheet, between which the driver 15 is guided. The driver 15 has openings through which two pins 18 are inserted, so that the driver 15 is guided on opposite sides in a guide track 16 in a metal plate 14a or 14b. The driver 15 also has a receptacle for inserting a section of the connecting part 20, which is connected to the energy accumulator 19. The energy accumulator 19 comprises an extendable piston rod 28, which is connected to the connecting part 20 and presses the driver 15 into the end position on the linear section of the guide track 16. The piston rod 28 is guided by a holder 29 between the two metallic plates 14a and 14b.On the opposite side, the energy accumulator 19 is fixed to a holding element 23, which is screwed to the sliding sash 3 or secured by other fastening means. The two metal plates 14a and 14b overlap the holder 21 and have a recess for this purpose. On the side opposite the holding element 23, another holder 24 is provided, to which the two metal plates 14a and 14b are held via pins 26. The holder 24 can also be screwed to the sliding sash 3.

[0038] In the illustrated embodiment, only one self-closing mechanism 13 is provided between the frame 2 and the sliding sash 3. It is also possible to provide two or more self-closing mechanisms 13 to increase the forces.

[0039] The self-closing mechanism 13 can also have a damper to slow down the movement of the sliding sash 3 in the closing direction and thus prevent loud impact noises. Such a damper can also be mounted separately from the self-closing mechanism 13 between the frame 2 and the sliding sash 3. List of reference symbols
