Description

Technical Field

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

[0002] EP2829679B1 discloses a door of this type, which allows heavy leaf loads to be supported. However, in order to seal this known door, a stop must be provided for the leaf in the sill area. Therefore, the barrier-free degree of the known door is not enough.

[0003] To make the home suitable for seniors, it is desirable to design the sliding doors to be as barrier-free as possible.

[0004] DE 10 2016 105 941 Al discloses the use of a substantially flat sill with drainage openings.

[0005] DE102017130894A1, DE102017130912A1, DE102019135411A1, DE102020102901A1, DE202017001325U1, EP3502399B1, EP3596295B1 and NL2004524C disclose low-obstacle lift sliding doors.

[0006] DE 10 2019 211 790 Al and DE 10 2019 211 794 Al disclose fittings for low-obstacle sliding doors with transversely parkable sashes (extension transverse to the door's sliding rails).

[0007] A problem with known low-obstruction sliding doors is that the sash becomes increasingly heavy due to the multiple glazing and the increased size, so that lateral parking of the sash can only be achieved in a constructionally complex manner. Summary of the invention

[0008] Therefore, the task of the present invention is to provide a sliding door which is simple in design, can bear heavy leaf loads, is reliable in sealing and is barrier-free.

[0009] According to the invention, this object is achieved by a door as claimed in claim 1. The dependent claims provide preferred developments.

[0010] Therefore, the object of the present invention can be achieved by a door as described at the beginning, the sill of which has a groove on the upper side, whose respective maximum horizontal width (perpendicular to the extension of the sliding rail) does not exceed 50 mm, in particular 45 mm, preferably 40 mm and / or whose respective maximum vertical depth does not exceed 3 mm, in particular 2 mm.

[0011] The door of the present invention allows the door to pass through the threshold without any hindrance even if the door is very heavy.

[0012] Position designations such as "upper", "lower", "above", "below", "lateral", "transverse", etc. relate to the assembly state of the door.

[0013] The roller element can be designed in multiple parts and have, for example, a suspension device and / or a vertical height adjustment device.

[0014] The guide rail can be designed in particular in the form of an upwardly directed rail or running groove.

[0015] Particularly preferably, the leaf extends into the leaf groove of the sill at the bottom. The door is thus particularly well sealed.

[0016] Here, the upper side is understood to be the upper tension envelope surface of the sill. Therefore, the upper side of the sill defines an imaginary envelope surface. If a thick or hard cloth is placed on the sill, it will fall on the upper side of the sill.

[0017] A door having the following characteristics:

[0018] a) Threshold with slide rails;

[0019] b) a leaf movable parallel to the slide rail, the leaf being supported downwardly on the slide rail by a door carriage;

[0020] The carriage has a roller component having rollers rolling on a guide rail and a control slide extending at least in sections obliquely to the main plane of the sash, wherein the roller component is designed to be movable transversely to the main plane of the sash;

[0021] and the sash has a transmission rod having a control pin arranged or formed on the transmission rod, the control pin extending into the control slide slot, so that movement of the transmission rod in its longitudinal direction causes movement of the roller member transversely to the main plane of the sash, thereby causing the sash to move transversely to the slide rail;

[0022] The leaf is thereby partially sunk at its underside into a leaf recess of the sill, so that the leaf extends partially below the top side of the sill.

[0023] The above described door represents an independent aspect of the present invention. The above described combination of features may be combined with all other features described herein.

[0024] It is particularly preferred that the upper side of the sill is perpendicular to the slide rail and the angle between the upper side and the horizontal plane is no more than 25°, particularly no more than 20°, preferably no more than 15° at any position. In this way, the sill can be rolled over particularly easily.

[0025] The leaf groove or the leaf can have a sealing strip extending parallel to the slide rail and sealing the leaf relative to the sill in its closed position.

[0026] The leaf can extend below the uppermost end of the slide rail on the lower side. Thus, although the door is barrier-free, its sealability is particularly good.

[0027] A door, wherein the door has the following features:

[0028] a) Threshold with slide rails;

[0029] b) a leaf movable parallel to the slide rail, the leaf being supported downwardly on the slide rail by a door carriage;

[0030] The carriage has a roller component having rollers rolling on a guide rail and a control slide extending at least in sections obliquely to the main plane of the sash, wherein the roller component is designed to be movable transversely to the main plane of the sash;

[0031] and the sash has a transmission rod having a control pin arranged or formed on the transmission rod, the control pin extending into the control slide slot, so that movement of the transmission rod in its longitudinal direction causes movement of the roller member transversely to the main plane of the sash, thereby causing the sash to move transversely to the slide rail;

[0032] The sash extends in its lower section below the uppermost point of the slide rail.

[0033] The above described door represents an independent aspect of the present invention. The above described combination of features may be combined with all other features described herein.

[0034] The slide rail can be constructed on a track which can be locked, clamped and / or pressed, in particular vertically, onto at least one other part of the sill. In a further embodiment of the invention, the slide rail is constructed on a swingable track. The track can preferably be swung in about the longitudinal axis of the slide rail or about an axis extending parallel to the longitudinal axis of the track. Particularly preferably, the track is locked to at least one other part of the sill in its mounting end position. In this way, the slide rail is particularly easy to mount.

[0035] The slide rail may be arranged or formed on an accessory component of the sill. The accessory component may convert a non-barrier-free door into a barrier-free door.

[0036] Particularly preferably, the slide rail is formed on a track that can be locked, clamped and / or pressed into the accessory part. In particular, the track can be swung into the accessory part and locked.

[0037] The sash may have an extension member extending downwards on the underside. The extension member may be subsequently mounted on the sash to provide a sash that extends further downwards.

[0038] In another preferred embodiment of the invention, the groove on the upper side of the sill is delimited by jumpers extending parallel to the track, which jumpers are located in a (virtual) plane. Whenever the upper side is interrupted by a groove, two jumpers are formed at the two upper corners of the groove. When a walker or a wheelchair passes over the groove, the wheels of the walker or wheelchair should jump from one jumper to the opposite jumper.

[0039] In a particularly preferred design of the present invention, the vertical height difference of all adjacent jumpers (having grooves between them) is less than 3 mm, particularly less than 2 mm, particularly preferably less than 1 mm, and the width of the groove is less than 50 mm, particularly less than 45 mm, preferably less than 40 mm.

[0040] This design makes it possible to roll over the threshold with particularly little resistance.

[0041] If the carriage has a fastening element arranged on the sash, which fastening element has a guide slot through which the control pin passes, loads transverse to the main plane of the sash can be safely guided away by the carriage. The roller element can be arranged on the fastening element so as to be movable transverse to the main plane of the sash. Preferably, the roller element is guided on the fastening element by a dovetail guide.

[0042] The sill can have a first guide groove extending parallel to the track, in particular directly beside the slide rail, wherein the first projection of the carriage extends downward beyond the at least one pulley into the first guide groove, so that when the leaf is loaded transversely to the main plane of the leaf, the carriage can be supported by the first projection on the side wall of the first guide groove or on the side of the slide rail. In this way, forces acting transversely to the main plane of the leaf, such as wind forces or forces of attempted entry, can be reliably introduced, while still ensuring that the door is unobstructed. Alternatively or additionally, the first projection can also extend downward beyond the upper side.

[0043] The first projection can have a bearing which can roll on the side wall of the first guide groove or on the side of the guide rail when the leaf is loaded transversely to the main plane of the leaf. This ensures low-friction and low-noise movement of the door parallel to the extension direction of the guide rail, even in the case of heavy loads on the leaf transversely to its main plane or structural deviations in the sill area.

[0044] The bearing can be constructed in multiple parts. The bearing can have a sleeve and a sleeve. The sleeve preferably has a low friction coefficient, for example, it is designed with PTFE.

[0045] The roller component may have a rivet pin for fixing the bearing. Alternatively or additionally, the first protrusion may have a cap for retaining the bearing.

[0046] The roller component may include an attachment with the first protrusion, which is fastened to the roller component body. The attachment is preferably fastened to the roller component body in a rotationally fixed manner. The attachment may be riveted to the roller component body.

[0047] Preferably, the roller component body has a downwardly extending fastening pin for receiving a transverse roller, and the accessory is fastened to the transverse roller, thereby making it convenient to retrofit the accessory.

[0048] Furthermore, the roller element can have a second projection which extends downward beyond the at least one pulley into the first guide groove so that the sash is supported by the second projection on the side wall of the first guide groove or on the side of the guide rail when the sash is loaded transversely to the main plane of the sash. Alternatively or additionally, the second projection can also extend downward beyond the upper side.

[0049] The second projection is particularly preferably arranged or formed on the attachment. The second projection ensures that a relatively large force can be guided out. Thus, forces transverse to the main plane of the sash can also be guided out to the sill without generating a torque on the attachment.

[0050] The first protrusion and the second protrusion may be configured identically.

[0051] In addition to the first guide groove, the sill can also have a second guide groove extending parallel to the slide rail, especially close to the slide rail, wherein the slide rail is located between the two guide grooves, and wherein another protrusion extends downward beyond the at least one roller (especially the upper side) into the second guide groove, so that when the sill is loaded transversely to the main plane of the sill, the slide bracket is supported on the side wall of the second guide groove or the side of the slide rail through the other protrusion.

[0052] The second guide groove may be formed in a mirror-symmetrical manner with respect to a virtual plane located in the middle of the slide rail, the virtual plane extending vertically and in the longitudinal direction of the slide rail.

[0053] The first guide groove and the second guide groove may be configured identically.

[0054] The design of the door can be further simplified if the attachment is designed to be radially symmetrical with respect to a (virtual) plane extending vertically and centrally in the longitudinal direction of the guide rail.

[0055] The horizontal width of the upper groove perpendicular to the slide rail is greater than 0 mm, particularly greater than 1 mm, and preferably greater than 5 mm. The vertical depth of the upper groove is greater than 0 mm, particularly greater than 1 mm, and preferably greater than 2 mm.

[0056] Other advantages of the present invention are derived from the description and the drawings. Likewise, according to the present invention, the above-mentioned features and the features described below can be used individually or in any combination. The embodiments shown and described should not be understood as exhaustive, but have exemplary features for explaining the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] FIG. 1a shows a door 10 with a leaf 12 and a threshold 14. The threshold 14 has a slide rail 16 which in this case extends into or out of the plane of the paper. The leaf 12 is supported on the slide rail 16 by a carriage 18. Figure 1a The fan 12 is shown in the unlocked state.

[0074] Figure 1b The door 10 according to FIG. 1a is shown in a locked state. Figure 1b As can be seen, the carriage 18 has a fastening component 20, which is immovably arranged on the leaf 12. The carriage 18 also has a roller component 22, which can move horizontally and transversely (here perpendicularly) to the fastening component 20. Here, the fastening component 20 can move transversely to the extension direction 24 of the slide rail 16 (indicated by a circled cross in Figure 1b). More precisely, the fastening component 20 can be forced to move transversely, here perpendicularly, to a virtual plane 26 at the center of the slide rail 16, which extends vertically and in the longitudinal direction of the slide rail 16. The movement of the leaf 12 transversely, here perpendicularly to its leaf main plane 28 (which extends parallel to the midplane 26 here) causes the leaf 12 to transfer from the unlocked state shown in Figure 1a to the locked state shown in Figure 1b.

[0075] 1b, it can also be seen that the leaf 12 is sealed relative to the sill 14 in the locked state by a sealing device 30. The sealing device 30 extends parallel to the midplane 26. The sealing device 30 has a sealing strip 31, which is arranged on the leaf 12 or (as in the present case) on the sill 14.

[0076] In order to achieve a good sealing effect and still realize an obstacle-free design of the door 10, the lower end of the leaf 12 extends into the threshold 14, more precisely, into the leaf groove 32 of the threshold 14. In this case, the lower end of the leaf 12 extends below the upper side of the slide rail 16, that is, the leaf 12 extends with its lower side below the uppermost surface section of the slide rail 16.

[0077] Figure 2a Another embodiment of a door 10 with a leaf 12 is shown, which has an extension part 34 at the lower end. The extension part 34 projects into the leaf recess 32 of the sill 14.

[0078] In addition to the scallop groove 32, the sill 14 also has a first guide groove 36 and a second guide groove 38 on the upper side. The slide rail 16 is directly adjacent to these guide grooves 36 and 38. In general, the scallop groove 32 and the guide grooves 36 and 38 represent the grooves 40 of the sill 14. The sill 14 can have more grooves 40 on its upper side 42. The upper side 42 can be understood as the envelope surface (at Figure 2a In the sectional side view of FIG. 4 , the envelope curve of the upper side 42 is indicated by a dashed line). When observing the upper side 42, "soft parts", such as the sealing strip 31, are preferably not taken into account.

[0079] Figure 2b Show Figure 2a The door 10 in the embodiment is in a locked state. Figure 2b It can be seen that the maximum width B of each groove 40 does not exceed 50 mm. Alternatively or additionally, the maximum depth T of each groove 40 does not exceed 3 mm. In this way, the sill 14 is designed to be particularly easy to drive over.

[0080] Figure 3a A further embodiment of a door 10 with a leaf 12 and a threshold 14 is shown, in which the leaf 12 passes through the upper side 42 of the threshold 14 at the lower end but ends above the running rail 16 .

[0081] 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 groove 40 (see Figure 2b The jumpers 44a-d are preferably located on a virtual plane 46 so that the sill 14 can be rolled over particularly easily. The vertical height difference of all adjacent jumpers 44a-d (with a groove 40 between them) is preferably less than 3 mm, in particular less than 2 mm.

[0082] Figure 3b Show Figure 3a The door 10 in the embodiment is in a locked state. Figure 3bIt can be seen that the threshold 14 has at least one accessory part 48a, 48b, here two accessory parts 48a, 48b. This / these accessory parts 48a, 48b make it possible to retrofit the door into a barrier-free door 10. In contrast, it is understood that the threshold 14 can also be designed in one piece.

[0083] In this example, the guide rail 16 is formed on a rail 50, i.e. a rail-shaped component, here a plate-shaped component. The rail 50 can be pivoted about an axis 52 so that it can be easily mounted on the accessory part 48b. The axis 52 extends parallel to the longitudinal axis of the guide rail 16. In the pivoted state, the rail 50 is locked on the accessory part 48b. In an alternative design, the rail 50 can be formed integrally with the accessory part 48b. In other words, the accessory part 48b itself can contain the guide rail 16.

[0084] A preferred design of the carriage 18 for the barrier-free door 10 is described below.

[0085] Figure 4a A transmission rod unit 54 is shown with a transmission rod 56 and a control pin 58. The control pin 58 is arranged or formed rotatably or non-rotatably on the transmission rod 56. The transmission rod 56 is arranged on the sash 12 so as to be movable in the direction of its longitudinal axis 60 (see, for example, FIG. 1a).

[0086] Figure 4b The slide 18 is shown with a fastening member 20 which can be mounted on the sash 12 (see FIG. 1a). The fastening member 20 has a guide slot 62. The control pin 58 (see FIG. Figure 4a ) passes through the guide slot 62 and extends into the control slot 64 of the roller element 22. The roller element 22 can be guided transversely, here perpendicularly, to the longitudinal axis 60 (see FIG. Figure 4a )—or the longitudinal extension direction of the guide slot 62—moves relative to the fastening component 20.

[0087] The roller element 22 has at least one roller 68 a , 68 b , here exactly two rollers 68 a , b .

[0088] The movement of the roller assembly 22 is controlled by the movement of the transmission rod 56 in the direction of its longitudinal axis 60 (see Figure 4a ) is carried out. Figure 4c and Figure 4d Provide explanation.

[0089] Figure 4c and Figure 4d The control pin 58 (shown in dashed lines) is shown Figure 4a ) is a top view of the carriage 18. Figure 4c and Figure 4dIt can be seen that the control link 64 is designed 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 roller assembly 22.

[0090] Figure 5a and Figure 5b A variant of a carriage 18 is shown with an attachment 70. The attachment 70 is arranged on a (in particular vertically extending) fastening pin 72 of the roller element 22. The fastening pin 72 is part of the roller element body 73. The attachment 70 is preferably riveted on.

[0091] The attachment 70 has a first protrusion 74 and a second protrusion 76. In this example, these protrusions 74 and 76 can be designed to be identical. Figure 2a ), these projections 74, 76 are arranged on the same side of the carriage 18. Due to the arrangement on the same side of the carriage 18, the attachment 70 is arranged on the fastening pin 72 in a particularly torsionally fixed manner.

[0092] In order to make the movement of the carriage 18 particularly quiet even when there are tolerances in the door 10 due to its construction (see FIG. 1a), the projections 74, 76 can have bearings 78, 80. The bearings 78, 80 can each have a sleeve 82, 84 and / or a cap 86, 88.

[0093] Figure 6a and Figure 6b A variant of the carriage 18 is shown, in which the projections 74, 76 carry bearings 78, 80, wherein the bearings 78, 80 are fixed by rivets 90, 92, respectively. The bearings 78, 80 have sleeves 82, 84 and sleeves 94, 96, respectively. The sleeves 94, 96 can be made of a low-friction material, such as PTFE (polytetrafluoroethylene). The sleeves 94, 96 can also be formed integrally with the sleeves 82, 84, respectively.

[0094] Figure 7a and Figure 7b Another variant of the carriage 18 is shown with a first protrusion 74, a second protrusion 76 and further protrusions 98, 100. These protrusions 74, 76, 98, 100 are formed symmetrically with respect to the midplane 26 (see FIG. 1 b), so that these protrusions 74, 76, 98, 100 can extend into two guide grooves 36, 38 (on both sides of the slide rail 16, see FIG. 1 b). Figure 2a ).

[0095] from Figure 1a to Figure 2bIt can be seen that this / these protrusions 74, 76, 98, 100 are preferably designed to be deeper in the vertical direction than the upper side of the guide rail 16, in particular than the upper side 42. Therefore, this / these protrusions 74, 76, 98, 100 preferably protrude below the upper edge of the guide rail 16, in particular below the upper side 42.

[0096] In summary, therefore, looking at all the figures, the present invention relates to a door 10 with an unobstructed sill 14. The sill 14 preferably has a groove 40 on its upper side 42, whose width B is less than 50 mm and / or whose depth T is less than 3 mm. The leaf 12 can pass through the upper side 42 in the leaf groove 32. The leaf 12 can be lower than the vertical uppermost dimension of the slide rail 16. In the event of wind loads or attempted intrusion, a reliable sealing or lateral support of the leaf 12 can be achieved by at least one protrusion 74, 76, 98, 100 of the carriage 18 extending into the guide grooves 36, 38. Preferably, the protrusions 74, 76, 98, 100 extend further downwards than the pulleys 68a, b of the carriage 18. The present invention makes it possible to form a particularly stable but still unobstructed door 10.
