Description

Technical Field

[0001] The invention relates to a door (door, sliding door or window door) according to the preamble of claim 1, the door having a slide rail, a door leaf movable parallel to the slide rail and a slide, the slide rail having a threshold, the door leaf being supported on the slide rail at the bottom by the slide. The slide has a rolling part, which has at least one pulley and a control slide extending at least partially obliquely to the main plane of the door leaf. The rolling part is designed to be movable transversely to the main plane of the door leaf. The door leaf has a transmission rod, which has a control pin arranged or constructed on the transmission rod, which extends into the control slide, so that the movement of the transmission rod in the direction of its longitudinal axis causes the movement of the door leaf transversely to the slide rail. Background Art

[0002] A door of this type is known from EP 2 829 679 B1, which allows heavy door leaf loads to be taken up. However, in order to seal the known door, it is necessary to provide a stop for the door leaf in the threshold region. Therefore, this known door is only insufficiently designed to be free of obstacles.

[0003] In order to construct elderly-friendly housing, sliding doors need to be constructed to be as barrier-free as possible.

[0004] DE 10 2016 105 941 A1 discloses the use of a threshold which is as flat as possible with a water drain opening.

[0005] DE 10 2017 130 894 A1, DE 10 2017 130 912 A1, DE 10 2019 135 411 A1, DE 10 2020 102 901 A1, DE 20 2017 001 325 U1, EP 3 502 399 B1, EP 3 596295 B1 and NL 2 004 524 C disclose barrier-free lift-sliding doors.

[0006] From DE 10 2019 211 790 A1 and DE 10 2019 211 794 A1 fittings for barrier-free sliding doors with a door leaf having a transverse adjustment (transverse to the extension of the running rail of the door).

[0007] A problem with known barrier-free sliding doors is that, due to their multiple layers of glazing and increasing size, the door leaf becomes increasingly heavy, so that a lateral adjustment of the door leaf can only be achieved in a constructionally complex manner. Summary of the invention

[0008] The object of the present invention is therefore to provide a movable door which is of simple construction, can withstand heavy door leaf loads, can be reliably sealed and is of unobstructed construction.

[0009] This object is achieved according to the invention by a door according to claim 1. The dependent claims reflect preferred developments.

[0010] The object according to the invention is therefore achieved by a door as described at the outset, wherein the threshold has a first guide groove which extends parallel to the guide rail, in particular directly adjacent to the guide rail, wherein a first projection of the carriage extends downward over at least one roller into the first guide groove, so that when the door leaf is loaded transversely to the main plane of the door leaf, the carriage can be supported by the first projection on the side walls of the first guide groove or on the side of the guide rail. In this way, forces acting transversely to the main plane of the door leaf, for example due to wind or attempted entry, can be reliably introduced, wherein the accessibility of the door is also ensured. Alternatively or additionally, the first projection can extend downwardly beyond the upper side.

[0011] The door according to the invention enables barrier-free traversability of the threshold even with heavy door leaves.

[0012] The position designations “upper”, “lower”, “above”, “below”, “lateral”, “transverse” etc. relate to the assembly state of the door.

[0013] The rolling part can be designed in multiple parts and have, for example, spring elements and / or vertical height adjustment elements.

[0014] The slide rail can be designed in particular in the form of an upwardly directed rail or a slide recess.

[0015] Here, "upper side" is understood to mean the tensioned upper envelope of the threshold. The upper side of the threshold thus defines an imaginary envelope surface. If a thick or dense cloth is placed on the threshold, it will lie flat on the upper side of the threshold.

[0016] If the carriage has a fixed part arranged on the door leaf with a guide slot through which the control pin passes, loads transverse to the main plane of the door leaf can be transmitted particularly reliably by the carriage. The rolling part can be arranged on the fixed part in a movable manner transverse to the main plane of the door leaf. The rolling part is preferably guided on the fixed part by a dovetail guide.

[0017] The first projection can have a bearing which can roll on the side walls of the first guide groove or on the side of the guide rail when the door leaf is loaded transversely to its main plane. This allows a low-friction and low-noise movement of the door parallel to the extension of the guide rail even when the door leaf is loaded transversely to its main plane or structural deflections occur in the area of ​​the threshold.

[0018] The bearing can be constructed in multiple parts. The bearing can have a bushing and a sleeve. The bushing preferably has low friction values, for example due to being constructed from PTFE.

[0019] The rolling part may have a rivet bolt for fixing the bearing. Alternatively or additionally, the first projection may have a cap for retaining the bearing.

[0020] The rolling part can have an attachment with a first protrusion, which is fixed to the rolling part body. The attachment is preferably fixed to the rolling part body in a non-twistable manner. The attachment can be riveted to the rolling part body.

[0021] The rolling part body preferably has a downwardly extending fixing pin for receiving a transverse wheel on which the attachment is fixed. Thus, the attachment can be easily retrofitted.

[0022] The rolling part can also have a second projection, which extends downward over the at least one pulley into the first guide groove, so that the door leaf can be supported on the side wall of the first guide groove or on the side of the guide rail by the second projection when the door leaf is loaded transversely to the main plane of the door leaf. Alternatively or additionally, the second projection can extend downward over the upper side.

[0023] Particularly preferably, the second projection is arranged or configured on the attachment. The second projection ensures that greater forces can be taken up. As a result, forces can be directed further transversely to the main plane of the door leaf into the threshold without generating a torque on the attachment.

[0024] The first protrusion and the second protrusion may be configured identically.

[0025] In addition to the first guide groove, the door sill can also have a second guide groove extending parallel to the slide rail, in particular directly adjacent to the slide rail, wherein the slide rail is located between the two guide grooves, and wherein a further protrusion extends downward over at least one pulley, in particular over the upper side into the second guide groove, so that when the door leaf is loaded transversely to the main plane of the door leaf, the slide can be supported on the side wall of the second guide groove or on the side of the slide rail by the further protrusion.

[0026] The second guide groove may be configured to be mirror-symmetrical with respect to a virtual plane in the middle of the slide rail, the virtual plane extending vertically and in the longitudinal direction of the slide rail.

[0027] The first guide groove and the second guide groove may be configured identically.

[0028] The construction of the door is further simplified if the attachment part is designed mirror-symmetrically with respect to a (virtual) plane extending vertically and centrally in the longitudinal direction of the guide rail.

[0029] The horizontal width of the upper recess perpendicular to the slide rail is greater than 0 mm, especially greater than 1 mm, preferably greater than 5 mm. The vertical depth of the upper recess is greater than 0 mm, especially greater than 1 mm, preferably greater than 2 mm.

[0030] Further advantages of the present invention are derived from the description and the drawings. Likewise, the above-mentioned features and the features still to be described in further detail can be used individually or in any combination according to the present invention. The embodiments shown and described should not be understood as an exhaustive enumeration, but rather have exemplary features for describing the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Figure 1a The door 10 is shown with a door leaf 12 and a threshold 14 . The threshold 14 has a guide rail 16 which in the present case extends into the plane of the paper or extends out of the plane of the paper. The door leaf 12 is supported on the guide rail 16 by a carriage 18 . Figure 1a The door leaf 12 is shown in an unlocked state.

[0049] Figure 1b Shows the locked state according to Figure 1a Door 10. From Figure 1b It can be seen that the carriage 18 has a fixed part 20 which is arranged immovably on the door leaf 12. The carriage 18 also has a rolling part 22 which can be moved horizontally and transversely (here vertically) relative to the fixed part 20. Here, the fixed part 20 can be moved transversely to the extension direction 24 of the guide rail 16 (in Figure 1b More precisely, the fixing part 20 can be movable in a controlled manner transversely (here perpendicularly) to an imaginary plane 26 in the middle of the guide rail 16, which extends vertically and in the longitudinal direction of the guide rail 16. The movement of the door leaf 12 transversely (here perpendicularly) to its main leaf plane 28 (which here extends parallel to the center plane 26) causes the door leaf 12 to move from Figure 1a The unlocked state shown is Figure 1bThe lock state transition is shown.

[0050] from Figure 1b It can also be seen that the door leaf 12 is sealed relative to the threshold 14 in the locked state by a seal 30. The seal 30 extends parallel to the center plane 26. The seal 30 has a sealing strip 31 which is arranged on the door leaf 12 or, as in the present case, on the threshold 14.

[0051] In order to achieve a good seal and also an obstacle-free design of the door 10, the door leaf 12 projects at the lower end into the threshold 14, more precisely into the door leaf recess 32 in the threshold 14. In the present case, the door leaf 12 projects at the lower end below the upper side of the running rail 16, that is, the door leaf 12 extends with its lower side below the uppermost surface section of the running rail 16.

[0052] Figure 2a An alternative embodiment of a door 10 is shown with a door leaf 12 which has an extension 34 at the lower end. The extension 34 projects into the door leaf recess 32 of the threshold 14.

[0053] In addition to the door leaf recess 32, the threshold 14 has a first guide groove 36 and a second guide groove 38 on the upper side. The guide rail 16 is adjacent to the guide grooves 36, 38. In general, the door leaf recess 32 and the guide grooves 36, 38 represent a recess 40 of the threshold 14. The threshold 14 can have further recesses 40 on its upper side 42. The upper side 42 is understood here to mean an envelope surface (at the bottom) covering the threshold 14. Figure 2a In the sectional side view of FIG. 4 , the envelope of the upper side 42 is drawn by a dashed line). When observing the upper side 42, "soft components", such as the sealing strip 31, are preferably not taken into account.

[0054] Figure 2b Shows the locked state Figure 2a Door 10. From Figure 2b It can be seen that the respective maximum width B of the recess 40 does not exceed a value of 50 mm. Alternatively or additionally, the respective maximum depth T of the recess 40 does not exceed a value of 3 mm. The threshold 14 is thus designed to be particularly easy to cross.

[0055] Figure 3a A further embodiment of a door 10 with a door leaf 12 and a threshold 14 is shown, wherein the door leaf 12 projects at the lower end through an upper side 42 of the threshold 14 and ends above the running rail 16 .

[0056] The upper side 42 has jumpers 44a, 44b, 44c, 44d extending parallel to the slide rail 16. Figure 3a The jump lines 44a-d define the horizontal width B of the recess 40 (see Figure 2bThe jumpers 44a-d are preferably located on a virtual plane 46, so that the threshold 14 can be climbed over particularly easily. The vertical height difference of all adjacent jumpers 44a-d, between which there is a recess 40, is preferably less than 3 mm, in particular less than 2 mm.

[0057] Figure 3b Shows the locked state according to Figure 3a Door 10. From Figure 3b It can be seen that the threshold 14 has at least one attachment portion 48a, 48b, here two attachment portions 48a, b. The attachment portions 48a, b enable the door to be subsequently converted into an accessible door 10. It should be understood that the threshold 14 can also be constructed in one piece.

[0058] Here, the slide rail 16 is constructed on a track 50, that is, a track-shaped (here plate-shaped) component. The track 50 can be swung around an axis 52 so that it can be easily assembled on the attachment part 48b. The axis 52 extends parallel to the longitudinal axis of the slide rail 16. When swung inward, the track 50 is locked on the attachment part 48b. In an alternative configuration, the track 50 can be constructed in one piece with the attachment part 48b. In other words, the attachment part 48b itself can contain the slide rail 16.

[0059] A preferred configuration of the carriage 18 for the barrier-free door 10 is described below.

[0060] Figure 4a The drive rod unit 54 is shown with a drive rod 56 and a control pin 58. The control pin 58 is arranged or designed to be rotatable or non-rotatable on the drive rod 56. The drive rod 56 is arranged on the door leaf 12 (see for example) in a manner that it can move in the direction of its longitudinal axis 60. Figure 1a )superior.

[0061] Figure 4b The invention shows a device which can be mounted on the door leaf 12 (see Figure 1a ) on the carriage 18 of the fixed part 20. The fixed part 20 has a guide slot 62. The control pin 58 (see Figure 4a ) protrudes through the guide slot 2 and into the control slot 64 of the rolling part 22. The rolling part 22 is guided transversely (here perpendicularly) to the longitudinal axis 60 of the transmission rod 56 (see Figure 4a ) or the longitudinal extension of the guide slot 62 is movable relative to the fixing part 20.

[0062] The rolling part 22 has at least one pulley 68a, 68b, here exactly two pulleys 68a, b.

[0063] The movement of the rolling part 22 is forcibly controlled by the transmission rod 56 (see Figure 4a) is carried out in the direction of its longitudinal axis 60. This is referred to below Figure 4c and 4d To explain.

[0064] Figure 4c and Figure 4d The top view shows the control pin 58 (drawn in dashed lines) (see Figure 4a ) of the carriage 18. Figure 4c and 4d As can be seen in FIG. 1 , the control slot 64 is configured to be at least partially inclined with respect to the longitudinal axis 60 (see Figure 4a ), so that movement of the control pin 58 causes lateral movement of the rolling portion 22.

[0065] Figure 5a and Figure 5b A variant of a carriage 18 is shown with an attachment 70. The attachment 70 is arranged on a fixing pin 72, in particular extending vertically, of the rolling part 22. The fixing pin 72 is part of a rolling part body 73. The attachment 70 is preferably riveted.

[0066] The attachment 70 has a first protrusion 74 and a second protrusion 76. As in the present case, the protrusions 74, 76 can be constructed identically. Figure 2a ), the projections 74, 76 are arranged on the same side of the carriage 18. Therefore, they protrude into the same guide grooves 36, 38. Due to the arrangement on the same side of the carriage 18, the attachment 70 is arranged on the fixing pin 72 in a particularly torsion-proof manner.

[0067] In order to even in the door 10 (see Figure 1a ), the projections 74, 76 can have bearings 78, 80. The bearings 78, 80 can each have a sleeve 82, 84 and / or a cover 86, 88.

[0068] Figure 6a and 6b A variant of the carriage 18 is shown, in which the projections 74, 76 have bearings 78, 80, wherein the bearings 78, 80 are fixed by rivets 90, 92, respectively. The bearings 78, 80 have sleeves 82, 84 and bushings 94, 96, respectively. The bushings 94, 96 can be made of a low-friction material, such as PTFE (polytetrafluoroethylene). The bushings 94, 96 can also be constructed in one piece with the sleeves 82, 84, respectively.

[0069] Figure 7a and 7bAnother variant of the carriage 18 is shown having a first protrusion 74, a second protrusion 76 and further protrusions 98, 100. The protrusions 74, 76, 98, 100 are configured to be oriented with respect to the center plane 26 (see Figure 1b ) symmetrically, so that the protrusions 74, 76, 98, 100 protrude into the two guide grooves 36, 38 (on both sides of the slide rail 16, see Figure 2a ).

[0070] from Figures 1a to 2b It can be seen that one or more projections 74, 76, 98, 100 are preferably configured vertically deeper than the upper side of the guide rail 16, in particular deeper than the upper side 42. One or more projections 74, 76, 98, 100 preferably protrude below the upper edge of the guide rail 16, in particular the upper side 42.

[0071] Thus, by reviewing all the figures, the invention relates to a door 10 with an obstacle-free threshold 14. Reliable sealing or lateral support of the door leaf 12 in the event of wind loads or attempted intrusion is achieved by at least one projection 74, 76, 98, 100 of the carriage 18, which extends into the guide grooves 36, 38. The projections 74, 76, 98, 100 extend further downwards than the rollers 68a, b of the carriage 18. The invention makes it possible to construct a particularly stable and obstacle-free door 10.
