Description

TECHNICAL FIELD

[0001] The present invention relates to a sliding door unit and a sealing unit, in particular for a building. The invention relates to sliding doors and sliding windows, which are collectively referred to as sliding doors below. STATE OF THE ART

[0002] Doors, especially entrance doors, patio doors, balcony doors and sliding windows of buildings, require seals to protect against sound, drafts, light penetration, sometimes also smoke and, depending on the location, rain.

[0003] So-called drop-down seals are known for the lower area of ​​doors. These seals have sealing strips that can be moved using a lowering mechanism. The sealing strip seals the gap between the underside of the movable door leaf and the floor. A release button protruding from the front of the door leaf is pressed in or pulled out through the door frame when the door leaf is closed, acting on a lowering mechanism that lowers the sealing strip against a spring force. When the door leaf is opened, the sealing strip is raised again thanks to the restoring force of the spring. Such drop-down seals have the advantage that, when the sealing strip is raised, they do not slow the movement of the door leaf. These drop-down seals have proven themselves for years for doors with pivoting door leaves. An example with a press-in release button is disclosed in EP 0 509 961 A1. An example with a pull-out release is described in EP 2 888 428 A1.

[0004] The use of such drop-down seals in sliding doors is more complex because the leverage of pivoting door leaves is missing, requiring greater force to press the release button when closing. Furthermore, a sliding door leaf that is not locked will automatically reopen due to the return force of the spring.

[0005] WO 2017 / 068173 A1, WO 2017 / 190799 A1, and WO 2017 / 191273 A1 therefore disclose sealing units for sliding doors with an activation unit, which has a stationary, upwardly directed support surface and a support element that can be moved with the sliding door leaf and pivoted about an axis. When the sliding door leaf is closed, the support element rests with one end on the stationary support surface, causing it to pivot and allowing a second end to actuate the release button of the lowering mechanism. The stationary support surface is arranged laterally offset from the retaining profile rail of the sealing device and extends in the longitudinal direction of the retaining profile rail. This seal has proven effective for sealing the top and bottom of the sliding door leaf. When the door leaf is closed, no restoring forces from the spring-loaded door seal act on the movable door leaf.The movable sliding door leaf remains in the closed position without locking. Even when closing and opening the sliding door leaf, no significant additional force is required from the user. This type of seal is now known on the market as "zero force."

[0006] However, to seal the sides of the sliding doors, i.e. for vertical sealing, brush, lip or tube seals are still used, which are arranged either in the door frame and / or in the sliding sliding door leaf. PRESENTATION OF THE INVENTION

[0007] It is therefore an object of the invention to provide a sliding door unit and a sealing unit that optimizes the vertical sealing of a sliding door.

[0008] This object is achieved by a sliding door unit having the features of patent claim 1 and a sealing unit having the features of patent claim 15.

[0009] The sliding door unit according to the invention comprises at least one displaceable sliding door leaf and at least one vertical sealing device. The sealing device is arranged in or on the sliding door leaf. It has a longitudinal direction that extends perpendicular to a sliding direction of the sliding door leaf. The sealing device seals the sliding door leaf against a wall or door frame over almost its entire height. It comprises a retaining profile rail, an actuating mechanism, and a sealing strip arranged on the retaining profile rail. When the sliding door leaf is closed, the sealing strip can be automatically moved relative to the retaining profile rail by means of the actuating mechanism in order to seal against the wall or door frame. It has a triggering means protruding from the retaining profile rail for automatically actuating the sealing strip.The sliding door unit has a stationary activation unit which has a contact surface against which the triggering means rests when the sliding door leaf is closed and which is aligned such that a force component parallel to the longitudinal direction of the sealing device acts on the triggering means and counteracts a restoring force, such as a return spring, of the actuating mechanism.

[0010] The term "wing" is used in this text for the movable part of the door; it does not necessarily have to be pivotable, but can also be exclusively sliding or sliding and lifting.

[0011] Preferably, the contact surface is perpendicular to the longitudinal direction of the sealing device or forms a curved or flat inclined surface that runs obliquely to the longitudinal direction of the sealing device. The contact surface extends in particular perpendicularly or obliquely to the longitudinal direction of a retaining profile rail of the sealing device.

[0012] The special arrangement of the activation unit enables vertical sealing of the sliding door without the need for protruding seals on the visible sides of the door leaf, the door frame, or the wall. Furthermore, a seal can now be installed on the visible side of the door leaf. The vertical seal no longer needs to be attached to the front of the sliding door leaf.

[0013] In particular, it allows the use of familiar drop-down seals for the vertical sealing of the sliding door leaf. This minimizes manufacturing costs and reduces the product range. Furthermore, optimal sealing effectiveness is ensured.

[0014] Another advantage is that they allow the door to be closed with relatively little effort. Another advantage is that, even with this sealing device, no forces act on the closed, but not locked, sliding door leaf that could reopen it. Thus, the advantage of the "zero-force" sealing units mentioned above is utilized, while the activation unit can be designed in an extremely space-saving manner.

[0015] Preferably, the sealing device is arranged on or in the sliding door leaf such that the direction of movement of the sealing strip is perpendicular to the direction of movement of the sliding door leaf. This means that the seal seals on a front or rear side of the door leaf.

[0016] Preferably, the activation unit has a contact surface against which the triggering means rests when the sliding door leaf is closed and along which the triggering means moves during closing. As a result, a force component parallel to the longitudinal direction of the sealing device (D) acts on the triggering means to actuate the triggering means.

[0017] In some embodiments, the contact surface and the run-up surface are aligned with each other or are identical. In these embodiments, they form a common, preferably flat and preferably horizontally extending plane. In other embodiments, the contact surface borders the run-up surface but has a different configuration. For example, the contact surface runs horizontally and the run-up surface is an inclined surface. Other variants are explained further below.

[0018] In some embodiments, the release mechanism is arranged within the retaining profile rail or protrudes laterally from the retaining profile rail. Preferably, however, the release mechanism protrudes from the front or side of the retaining profile rail. When the sliding door leaf is closed, the release mechanism can preferably be pressed longitudinally into the retaining profile rail or pulled out of the retaining profile rail in order to move the sealing strip into a sealing position by means of the actuating mechanism.

[0019] In some embodiments, the release means can be pressed into the retaining profile rail when the sliding door leaf is closed in order to exert a compressive force on the actuating mechanism.

[0020] In other embodiments, the triggering means can be pulled out of the retaining profile rail when the sliding door leaf is closed in order to exert a pulling force on the actuating mechanism.

[0021] In some embodiments, a release mechanism is provided at only one end of the sealing device. In other embodiments, a release mechanism is arranged at each end of the retaining profile rail, with both being push-in or pull-out, or with a first push-in and the other pull-out.

[0022] Preferably, the triggering means comprises a rod-shaped base body and an end region, wherein the end region rests against the triggering means when the sliding door leaf is closed, and wherein the rod-shaped base body extends in the longitudinal direction of the sealing device and is operatively connected to the actuating mechanism. These preferred embodiments have the advantage that a variety of known and proven types of sealing devices can be used in the sliding door unit and sealing unit according to the invention.

[0023] The release mechanism preferably comprises a known or newly designed release button or an actuating roller. In some embodiments, the release mechanism comprises a roller or wheel with a rotation axis that runs perpendicular to the longitudinal direction of the sealing device and perpendicular to the sliding direction of the sliding door leaf. In these embodiments, the release mechanism can thus be designed in a space-saving and cost-effective manner.

[0024] In some embodiments, the triggering means has a free end that is beveled. This preferably, but not exclusively, applies to actuating buttons, including rod-shaped ones. This shape facilitates sliding on the contact and / or contact surface. The end, whether beveled or not, is preferably provided with a sliding layer.

[0025] In some embodiments, the inclined free end is chamfered at its front surface. This design is particularly suitable for release devices that can be pressed in upon closing.

[0026] In some embodiments, the angled free end forms a slanted surface that slopes toward the retaining profile rail. This design is particularly suitable for release devices that can be pulled out during closing.

[0027] The activation unit is fixed in place. It can be attached to the door frame, the wall, or a track or guide rail of the sliding door. In particular, it can be glued or attached with nails or screws. In other embodiments, the activation unit is an integral part of the track, support rail, or door frame.

[0028] The activation unit can be designed in different ways. It is preferably a one-piece construction. It preferably has a base body or consists of the base body, at least one surface of which forms the contact surface and, if present, the contact surface. The activation unit can thus be manufactured simply and cost-effectively, and can be designed in a space-saving manner.

[0029] In preferred embodiments, the base body of the activation unit has a flat, horizontally extending surface that forms only the contact surface. The contact surface, if present, is formed in a different shape and / or orientation, but preferably in the same base body.

[0030] In some embodiments, there is no additional, differently shaped and / or aligned run-up surface, but the contact surface is sufficiently long to also form the run-up surface.

[0031] In further embodiments, the base body has a flat or curved inclined surface, wherein the inclined surface forms the run-up surface and / or the contact surface.

[0032] In some embodiments, the inclined surface is inclined away from the retaining profile rail, particularly when the release means is pressed in when the door is closed.

[0033] In other embodiments, the inclined surface is inclined towards the retaining profile rail, particularly when the release means is pulled out when the door is closed.

[0034] In further embodiments, the activation unit comprises a roller, wherein the roller forms the contact and / or run-up surface. The roller is preferably rotatably mounted in a base body. In some embodiments, the contact surface of the roller is arranged downstream of the sliding door in the closing direction. However, the roller preferably also forms the contact surface.

[0035] In some embodiments, the base body has a valley or depression, with the release mechanism extending into the valley or depression when the sliding door is closed. This optimally secures the release mechanism and locks the sliding door. When opening the sliding door, a slightly increased force is required to allow the release mechanism to leave the valley or depression. This prevents the sliding door from being displaced by a gust of wind, a small child, or a pet.

[0036] The sealing unit according to the invention comprises the sealing device described above and the stationary activation unit of the sliding door unit described above. It can preferably be used in sliding doors that run in front of or within the wall, i.e., also for sliding doors with pockets or panels. It preferably seals on the visible side of the door frame or wall.

[0037] The activation unit can be installed above and / or below the door leaf, in particular on the door frame or floor or ceiling, on the wall or on the running or guide rail.

[0038] Further embodiments are specified in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Identical parts are provided with the same reference symbols. DESCRIPTION OF PREFERRED EMBODIMENTS

[0041] The Figures 1 and 2 show the same sliding door device according to the invention from two sides. It has a guide rail S arranged at the upper end and a sliding door leaf F that can be moved relative to a wall W and above a floor B. The illustration is purely schematic and does not show all the components of a sliding door. However, these are well known and therefore will not be described here.

[0042] The sliding door unit according to the invention has door seals. Any upper and lower door seals are not shown. They are known. However, the vertical sealing devices D are shown. In this example, sealing devices D are present at both ends of the sliding door leaf T. In this example, they are arranged on a rear side of the door leaf T, i.e., facing the door frame, particularly since the sliding door leaf T extends outside the door opening.

[0043] Figure 3shows part of a known drop-down seal or a sealing device D with a movable sealing strip 3. The sealing device D has a U-shaped, downwardly open retaining profile rail 1, on or in which the sealing strip 3 is arranged. The sealing strip 3 usually comprises a support profile rail (not visible in the figure) and a one-part or multi-part sealing profile. The sealing strip 3 can be actuated by means of a usually spring-loaded actuating mechanism arranged inside the retaining profile rail 1. A first release means 40, here a release button, protrudes from the support profile rail 1 on one side. Depending on the embodiment, a protruding first release means 40 is present on both end faces of the support profile rail.If the release button 40 is pressed in the direction of the support profile rail 1, the external force is transmitted to the actuating mechanism against a spring force, and the support profile rail, together with the sealing profile arranged thereon, is moved out of the support profile rail 1 transversely to the longitudinal direction of the support profile rail 1. When the force is applied to the release means 40, the restoring force of the spring pulls the sealing strip 3 back toward the support profile rail 1 or into it.

[0044] In Figure 4 An alternative embodiment of a sealing device is shown. It has the same features as the sealing device according to Figure 3 The only difference lies in the design of the trigger element. The second trigger element 41 shown here has a roller that can pivot or rotate about an axis arranged perpendicular to the longitudinal direction of the retaining profile rail 1.

[0045] Figure 5shows a sealing device D according to Figure 3 , arranged in a sliding door leaf T. The slide rail S is not shown. However, a door roller 6 shows how a possible connection of the door leaf T with the slide rail S can be designed.

[0046] In this example, the sealing device D is arranged in a groove N of the sliding door leaf T. It can be attached in a manner customary for drop-down seals, for example, using end-face brackets. These are not shown in the schematic drawing. The sealing device D is arranged perpendicular to the direction of movement of the door leaf T. The direction of movement is indicated by an arrow.

[0047] The sealing device D preferably extends over the entire height of the door leaf T. In this example, the triggering means 40 protrudes upwards. It thus protrudes from the support profile rail 1 and the door leaf T. An activation unit 50 is arranged in the end region of the closing path of the door leaf T. In the example, it is according to Figure 5 arranged, preferably fastened, on the slide rail S (not shown). The activation unit 50 consists of a substantially cuboid-shaped base body 500. It will be explained in more detail later in the text.

[0048] In Figure 5 The state of the door leaf T is shown shortly before the sliding door closes. The sealing device D and thus the trigger element 40 have just reached the activation unit 50. The sealing strip 3 has not yet been activated.

[0049] In Figure 6The closed state of the door leaf T is shown. The sealing device D and thus the trigger element 40 are located below the activation unit 50. The sealing strip 3 is actuated and rests against the wall W. The sealing device D forms a vertical seal of the door leaf T.

[0050] In the Figures 7 and 8 The triggering means and the activation unit are shown in a first embodiment. They are designated as the first triggering means 40 and the first activation unit 50. The first triggering means 40 is a trigger button with a cylindrical base body 400 and a beveled free end 401. The free end 401 is preferably provided with a sliding layer or the button is made of a plastic.

[0051] The first triggering means 40 is connected to an actuating rod 2. Its position relative to the actuating rod 2 is preferably adjustable via a threaded connection. When the sliding door is closed, the actuating rod 2 transmits the force acting on the first triggering means 40 to the actuating mechanism.

[0052] The first activation unit 50 has a cuboid-shaped base body 500 with flat surfaces. One end face is beveled. It forms a contact surface 501. The surface of the base body 500 adjacent to the beveled surface 501, here the lower surface, forms a contact surface 502. Figure 7The closing direction of the sliding door leaf T is indicated by an arrow. When the door leaf T is closed, the first release means 40 is pushed toward the stationary activation unit 50. The free end 401 strikes the inclined run-up surface 501 and slides along it, whereby the first release means 40, i.e., the release button, is pressed into the retaining profile rail 1, and the actuating mechanism moves the sealing strip 3 into the sealing position.

[0053] The first activation unit 50 is mounted such that the first triggering means 40 rests against the horizontally extending contact surface 502 when the sliding door leaf T is in the closed position. As a result, the restoring forces of the actuating mechanism act only in the vertical direction. They cannot reopen the sliding door leaf T automatically.

[0054] In the Figures 9 and 11 The position is shown before the sealing strip 3 is activated. In the Figures 10and 12 the closed position with sealing strip 3 is shown.

[0055] When opening the sliding door leaf T, the first release means 40 slides in the opposite direction of the arrow according to Figure 7 toward the inclined run-up surface 501 and is released again. The restoring force of the actuating mechanism can retract the sealing strip 3 back to the retaining profile rail 1.

[0056] In the Figures 13 to 21 Further embodiments of triggering means and activation units are shown, which can be used in the same way as described above. Further embodiments are possible.

[0057] In the Figures 13 and 14The first triggering means 40 is combined with a second activation unit 51. This second activation unit also has a cuboid-shaped base body 510 with a beveled surface 511 on the front side. However, a roller 512 is held in the base body 510. The beveled free end of the first triggering means 40 slides along this roller 512 when the sliding door is closed and rests against the roller 512 with the outermost edge of the free end 401 in the closed state. The roller 512 thus forms the contact surface as well as the contact surface.

[0058] In the embodiment according to Figure 15The first activation unit 50 is combined with a second triggering means 41. The second triggering means 41, in turn, has a cylindrical base body 40 connected to an actuating rod 2. A roller 411 is arranged at the free end, which slides along the inclined run-up surface 501 and, when the sliding door is closed, rests against the horizontally extending, flat contact surface 502.

[0059] In the embodiment according to the Figures 16 and 17 The first trigger element 40 is combined with a second activation unit 52. The second activation unit 52 has a cuboid-shaped base body 520 without any bevels. The exclusive contact surface for the first trigger element 40 is a flat, horizontally extending surface, which forms the contact surface 522.

[0060] Figure 17a shows a variant of the sixth activation unit 56, which represents a variant of the third activation unit. It has a wedge-shaped base body 560 that forms an inclined contact surface 562.

[0061] In the embodiment according to the Figures 18 and 19 The first trigger element 40 is combined with a third activation unit 53. The third activation unit 53 has a cuboid-shaped base body 530 with a rounded or curved end face, which forms the contact surface 531. The surface immediately adjacent in the closing direction is again flat and horizontal and forms the contact surface 532.

[0062] In the embodiment according to the Figures 20 and 21The first trigger element 40 is combined with a fourth activation unit 54. The fourth activation unit 54 has a cuboid-shaped base body 540, the end faces of which are rounded or curved and the central region of which forms a depression or valley. The first rounded end face in the closing direction of the sliding door forms the run-up surface 541, the central depression-shaped or valley-shaped area forms the contact surface 542, and the rear end face forms a limiter. The trigger element 40 rests in the depression or valley and thus fixes the sliding door in the closed position and prevents it from opening even with a small external force. The limiter is not absolutely necessary. The elevation of the run-up surface 541 relative to the contact surface 542 is sufficient to prevent it from opening. The elevation 543 serves as a damper for the closing movement of the sliding door leaf T.

[0063] In the Figures 25 and 26A release by pulling is shown. The release means 42 in turn has a rod-shaped base body 420, which is arranged in a sleeve 2. The free end 421 forms an inclined surface directed towards the retaining profile rail 1. The activation unit 55 has a wedge-shaped base body 550 with an upwardly directed inclined surface 552. When the door leaf T is closed, the inclined surface 421 of the release means 42 slides along the inclined surface 552 of the activation unit 55 and rests against it when the door is closed. The inclined surface 552 of the activation unit 55 thus forms the contact surface and the contact surface. The arrow in Figure 25 shows the closing direction of the door. The arrow in Figure 26 shows the pulling movement acting on the lowering mechanism.

[0064] The activation units and triggering devices mentioned above can be combined as desired.

[0065] In the above examples, the triggering means 40, 41, 42 protrudes vertically upwards and the activation unit 50, 51, 52, 53, 54, 55, 56 is arranged above the sliding door leaf T. Alternatively or additionally, a triggering means 40, 41 can protrude vertically downwards and the activation unit 50, 51, 52, 53, 54, 55, 56 can be arranged below the sliding door leaf T. This is shown in the Figures 22 to 24 shown.

[0066] The sliding door unit and the sealing unit according to the invention enable optimal vertical sealing of sliding doors. LIST OF REFERENCE SYMBOLS
