DESCRIPTION OF PREFERRED EMBODIMENTS
[0074] Different suspension assemblies 2 according to the invention of sliding doors 1 are shown in FIGS. 1 to 12. Identical or functionally equivalent elements of the different embodiments are in each case provided with the same reference signs hereunder.
[0075] FIG. 1 shows a two-leaf sliding door 1 which is assembled according to the intended use and has two door leaves 3 which for closing a passage opening provided in a wall W are displaceable along the closing direction marked with arrows. The two door leaves 3 herein are mutually displaceable so far that the two main closing edges 31 of the door leaves 3 come to bear on one another. For opening the sliding door 1, the two door leaves 3 are displaceable away from one another counter to the direction of the arrows. The closing direction herein extends perpendicularly to the direction of passage of the door. Sealing means for mutually sealing the door leaves 3 in the closed state of the sliding door 1 can in each case be provided along the main closing edges 31.
[0076] In order to enable displacing of the door leaves 3, the latter are hung so as to be displaceable on the wall W by means of a suspension assembly 2. The suspension assembly 2 is attached to the wall W so as to be stationary above the passage opening. The suspension assembly 2 has a horizontally running direction of longitudinal extent; the suspension assembly 2 extends parallel to the floor B in the longitudinal direction, said floor B delimiting the passage opening to be closed by the sliding door 1 toward the bottom.
[0077] The door leaves 3 have in each case an upper closing edge 32. Attached to the latter is/are in each case one or a plurality of carriages 7 which are not visible in FIG. 1 but can be seen in FIGS. 3 and 5, and which serve to hang the respective door leaf 3 on the suspension assembly 2. The lower closing edges 33 of the door leaves 3 run in each case directly along the floor B. First guiding means which for guiding the door leaves 3 interact with a second guiding means provided on the floor B in order to achieve a guided displacement of the door leaves 3 are preferably provided on the lower closing edges 33. The first guiding means can be, for example, one or a plurality of guiding blocks which engage in a guide rail that is provided on the floor B and is open toward the top. The guide rail is preferably sunk into the floor B.
[0078] A preferred first embodiment of a suspension assembly 2 according to the invention, as can be used in the sliding door 1 shown in FIG. 1, for example, will now be described by means of FIGS. 2 to 5. The suspension assembly 2 of FIGS. 2 to 5 can however also be used in other sliding doors 1 such as, for example, also in single-leaf sliding doors or in sliding doors with more than two displaceable door leaves 3.
[0079] For fastening the suspension assembly 2 to the wall W, the suspension assembly has a suspension part 4 which is shown in a stand-alone view in FIG. 2 in the state assembled on the wall W. The suspension part 4 in the present exemplary embodiment is a profiled rail, i.e. the suspension part 4 has a consistent cross section in terms of area and shape along its entire longitudinal extent. The cross section of the suspension part 4 can be readily seen in FIG. 2, the latter showing the frontal end of the profiled rail.
[0080] As can be seen in FIG. 2, the suspension part 4 has a wall portion 41 which runs vertically in the cross-sectional view and by way of which the suspension part 4 bears on the wall W. Fastening means such as, for example, bores or depressions provided with rearward engagement elements, are formed on the wall portion 41 so as to fasten the suspension part 4 to the wall W and in particular anchor said suspension part in the latter.
[0081] A door leaf portion 42 extends from the wall portion 41, at the lower end of the latter in the cross-sectional view, so as to be approximately perpendicular from the wall W toward the front in the direction of passage. The door leaf portion 42 serves to hold and in particular hang the door leaf, or door leaves, 3. The door leaf portion 42 for this purpose has a free end which forms a bearing element 43 which serves to bear the carriage, or carriages, 7 attached to the door leaves 3. The bearing element 43 here is covered with a covering 45 which forms a running surface 44. The carriage, or carriages, 7 in the state assembled according to the intended use, bear on the running surface 44, which here is curved convexly toward the top, in such a manner that said carriages 7 are displaceable along the running surface 44 in the longitudinal direction of the suspension part 4.
[0082] As in the present exemplary embodiment, depressions, guide rails, threaded bores, etc., for attaching various construction elements of the sliding door to the suspension part 4, such as sealing means or sensors, can be formed on the lower side of the door leaf portion 42.
[0083] A component portion 46 extends from the upper end of the wall portion 41 in the cross-sectional view of FIG. 2 so as to be approximately perpendicular from the wall W toward the front in the direction of passage. The component portion 46 has a free end which extends so as to be slightly inclined upward and forms a lower support element 47. As can be readily seen in FIG. 2, the lower support element 47 does not extend as far outward in the horizontal direction as the running surface 44. As a result, the space is clear for hanging a door leaf on the running surface 44, without the lower support element 47 getting in the way of the door leaf and in particular a carriage attached to the latter. Above the point from which the lower support element 47 extends so as to be inclined upward, the component portion 46 forms an upper support element 48 in the form of a projection which extends perpendicularly outward in terms of the wall W. However, the upper support element 48 is designed to be significantly shorter than the lower support element 47. The two support elements 47 and 48 have in each case a hook-shaped termination on their free end. In the lower support element 47, the hook extends upward, and downward in the upper support element 48. The component portion 46 by way of the two support elements 47 and 48 serves to hold a component part 5 (see FIGS. 4 and 5) to which are attached a drive motor 61 and further mechanical or electrical components.
[0084] Owing to the component portion 46, the wall portion 41 and the door leaf portion 42, the suspension part 4 has a C-shape design in the cross-sectional view.
[0085] FIG. 3 shows the same suspension part 4 attached to the wall W as in FIG. 2, but having a carriage 7 hung thereon. The carriage 7 comprises at least one roller and 72 by way of which the carriage 7 bears on the running surface 44 of the suspension part 4. The roller 72 has a concavely designed radial external face which is designed to be complementary to the running surface 44 which is convexly curved upward. The carriage 7 is guided by this when displaced along the running surface 44. Owing to the covering 45, which however also could be dispensed with in other embodiments, the rolling of the roller(s) 72 on the running surface 44 is performed in a particularly noise-reduced manner. The covering 45 is preferably produced from a plastics material.
[0086] The roller, or rollers, 72 is/are attached to a main support part 75 of the carriage 7 so as to be freely rotatable thereon, said main support part 75 running vertically in the cross-sectional view. A connecting element 71 which serves to fasten a door leaf 3 is attached to the lower end of the main support part 75. The connecting element 71 is usually attached to the upper closing edge 32 of the door leaf 3. For reasons of visualization, the door leaf 3 is not shown in FIGS. 3 and 5. The main support part 75 is advantageously adjustable in its height so that the spacing between the roller 72 and the connecting element 71 can be adjusted within specific limits.
[0087] Moreover, a counterpressure roller 73 is attached so as to be freely rotatable on the main support part 75 of the carriage 7. The counterpressure roller 73, the function thereof being explained further below with reference to FIG. 5, is disposed on the same side of the main support part 75 as the roller 72. However, said counterpressure roller 73 is positioned so as to be somewhat offset from the suspension part 4, as can be readily seen in the view of FIG. 3. Moreover, the counterpressure roller 73 is disposed somewhat higher than the roller 72 on the main support part 75.
[0088] Dogs 74 are attached to the main support part 75 on that side of the main support part 75 that lies opposite the roller 72 and the counterpressure roller 73, thus on the side facing away from the suspension part 4, said dogs 74 extending perpendicularly outward from said main support part 75. In the state assembled according to the intended use, the dogs 74 interact with a force-transmitting element such as, for example, a drive belt, the latter being connected to a drive motor, in order for the displacement of the door leaves 3 to be automated.
[0089] The component part 5 having the drive 6 attached thereto is shown in FIG. 4. FIG. 4 shows a lateral view onto an end face of the component part 5 which is designed as a profiled rail.
[0090] The component part 5 has a connecting portion 51 which during assembling of the suspension assembly serves to hang the component part 5 in the suspension part 4. The connecting portion 51 extends approximately along the horizontal direction and, in the state assembled according to the intended use, toward the suspension part 4. Said connecting portion 51 has a free end which extends so as to be slightly inclined downward toward the suspension part 4 and forms a hanging element 52. The hanging element 52 on the outer end forms a hook-shaped termination, whereby the hook extends slightly upward. Moreover, the connecting portion 51 on its lower side forms a flat counter running surface 53 which serves for bearing and rolling on the counterpressure rollers 73 attached to the carriage 7.
[0091] The connecting portion 51, on its side that faces away from the suspension part 4, transitions into an assembly portion 54 which extends outward along the horizontal direction. Various mounting elements such as, for example, bores, rearward engagement elements, assembly rails, etc., are formed on the lower side of the assembly portion 54. These mounting elements serve to attach the most varied components to the suspension assembly 2, such as in particular the drive 6. However, arbitrary further components can also be attached to the assembly portion 54 such as, for example, control elements, sensors, a mains supply unit, a travel detection unit and/or a transmission unit for communicating wirelessly or by wire with an external device.
[0092] The drive 6 shown in FIG. 4 has a drive motor 61 and an angle gearbox 62 connected thereto. A drive wheel 63 which serves to drive a drive belt not illustrated in the figures is attached to the gearbox 62 by way of a shaft. In the state assembled according to the intended use, the dogs 74 attached to the carriage, or carriages, 7 bear in each case on an element of the drive belt which runs horizontally along the upper closing edge 32, and as a result are entrained by the drive belt in a movement of the latter, as a result of which the sliding door 1 opens or closes, respectively. All of the components of the drive 6 are attached to the assembly portion 54 of the component part 5 from below, for example screwed thereto.
[0093] The assembled state according to the intended use of the suspension assembly 2 is shown in FIG. 5: The component part 5 by way of its hanging element 52 is hung on the component portion 46 of the suspension part 4 which is attached above the door passage opening on the wall W. The hanging element 52 of the component part 5 herein protrudes into the intermediate space which is formed by the lower support element 47 and by the upper support element 48. Because the lower support element 47 extends slightly upward toward its free end, and the hanging element 52 extends slightly downward toward its free end, the lower support element 47 and the hanging element 52 run parallel to one another in the hung state, as can be seen in FIG. 5.
[0094] As can moreover be seen in FIG. 5, the component part 4 in the hung state is supported from below by the lower support part 47 in a first support point S1, on the one hand, and supported from above by the upper support part 48 in a second support point S2, on the other hand. The center of gravity SP of the unit including the component part 4, the drive motor 61 and the further components, thus in particular the gearbox 62 and the drive wheel 63, lies approximately at the location indicated in FIG. 5 and is thus significantly spaced apart from the first support point S1 in the horizontal direction toward the outside. In this way, the first support point S1 is disposed so as to be spaced apart along the horizontal direction between the second support point S2 and the center of gravity SP of the component part 5 including the components 61, 62, 63 attached to the latter.
[0095] The component part 5 is thus supported from below by means of the lower support part 47 in the first support point S1. Due to gravity, the component part 5 is pulled toward the floor B in the center of gravity SP. However, this force acting toward the floor B is absorbed on the side lying opposite the first support point S1 by the upper support element 48 in the second support point S2, as a result of which the component part 5 has an overall stable position.
[0096] An inadvertent extraction of the hanging element 52 of the component part 5 from the component portion 46 of the suspension part is prevented by the two hooks which hook into one another and are formed on the respective free ends of the upper support element 48 and of the hanging element 52. Once the component part 5 has been hung on the suspension part 4 it is however advisable to fasten the two parts to one another by means of a securing element for safety reasons. For this purpose, the component part 5 and the suspension part 4 can in particular be screwed to one another at suitable locations.
[0097] As can moreover be seen in FIG. 5, the counterpressure roller 72, which is attached to the carriage 7, is disposed directly below the counter running surface 53 or even bears on the latter in the hung state of the component part 5. As a result, it can be prevented that the door leaf 3 attached to the carriage 7 pivots along the direction of passage. The counterpressure roller 72, which in other embodiments can also be designed as a counterpressure sliding element, as a result prevents in particular also that the door leaf 3 can be detached from the suspension part 4 in the completely assembled state of the sliding door 1.
[0098] The method for assembling a sliding door 1 having a suspension assembly designed according to FIGS. 2 to 5 is derived from the sequence of FIGS. 2 to 5:
[0099] In a first step, the suspension part 4 is fastened to a wall W above a passage opening (FIG. 2). In a second step, one or a plurality of door leaves 3 are hung on the suspension part 4 (FIG. 3). For this purpose, the carriage, or carriages, 7 attached to the door leaf 3 are placed on the running surface 44 of the suspension part 4 by way of the rollers 72 of said carriages 7. Because the component part 5 is in this instance not yet attached to the suspension part 4, and the space above the running surface 44 is clear for this reason, hanging the door leaf, or door leaves, 3 on the suspension part 4 is performed in a particularly simple manner. During hanging, space is in particular also available in the region of the counterpressure roller(s) 73. As a next step, the component part 5 to which the drive motor 61 and the further components 62, 63 are preferably already attached (FIG. 4) is then hung on the suspension part 4 (FIG. 5). For this purpose, the component part 5, with the hanging element 52 in front, has to be simply introduced into the space between the two support elements 47 and 48 of the component portion 46. Owing to the design of the hanging element 52 on the one hand, and of the upper support element 47 on the other hand, the hanging element 52 for this purpose can simply be placed on the lower support element 47 and subsequently be advanced obliquely downward along the latter up to the detent. As a result, the component part 5 is hung on the suspension part 4 in a stable position. For safety reasons, it is advisable to then also secure the component part 5 on the suspension part 4 with the aid of one or a plurality of securing elements 55. As a last step, a drive belt can then also be attached to the drive wheel 63 so as to connect the latter to the dogs 74 of the carriage, or carriages, 7.
[0100] The component part 5 on its outer end facing away from the suspension part 4 can have one or a plurality of connecting structures so as to enable a cover element, for example in the form of a sheet-metal cover plate, to be attached. The sheet-metal cover plate, or cover plates, can be attached to the component part 5 at the end of the assembling method, i.e. once the drive wheel 63 has been connected to the dogs 74 by way of a force-transmitting element.
[0101] Shown in FIG. 6 is a suspension assembly according to another embodiment which however is also according to the invention. The embodiment of FIG. 6 differs from that of FIGS. 2 to 5 only in the design embodiment of the component portion 46 of the suspension part 4 and of the connecting portion 51 of the component part 5.
[0102] In the embodiment of FIG. 6, the component portion 46 of the suspension part 4 is formed by a simple web which extends perpendicular toward the outside from the wall W and on its free end has a slightly upward protruding projection and forms a hook-shaped termination as a result.
[0103] The hanging element 52 of the connecting portion 51 is formed conjointly by two horizontal webs that extend so as to be mutually parallel, whereby the lower web extends somewhat farther toward the suspension part 4 than the upper web. The upper web on its free end has a slightly downward protruding projection and forms a hook-shaped termination as a result.
[0104] For hanging the component part 5, the latter is hung on the suspension part 4 in such a manner, as is shown in FIG. 6, that the horizontally protruding web of the component portion 46 is pushed into the intermediate space which is delimited by the two parallel webs of the hanging element 52 of the connecting portion 51. The free end of the web formed by the component portion 46 in the process supports the component part 5 from below in a first support point S1. Somewhat spaced apart therefrom, the component portion 46 simultaneously supports the component part 5 from above in a second support point S2. In this way, the web formed by the component portion 46 simultaneously forms here the lower support element 47 (in the region of its free end) as well as the upper support element 48 (in a region between the free end and the wall portion 41). The positions of the first and of the second support point S1, S2 and of the center of gravity SP of the component part 5 including the drive motor 61 and the further components attached thereto are however similar to those in the embodiment shown in FIG. 5.
[0105] Moreover shown in FIG. 6 is a securing element 55 in the form of a screw-and-nut connection between the component part 5 and the suspension part 4.
[0106] A further embodiment of a suspension assembly 2 according to the invention is shown in FIGS. 7 to 12. As can be seen in FIG. 7, the lower support element 47 here extends somewhat farther toward the outside in the direction of the component part 5, but still just not as far as the running surface 44. The lower support element 47 in the region of its free end forms a hook toward the top, said hook on its side that faces away from the component part 5 having an oblique face. The oblique face forms an undercut. In comparison to the embodiment of FIGS. 1 to 5, the lower support element 47 moreover extends, from the wall portion 41, somewhat more in the horizontal direction toward the outside, i.e. the inclination of the lower support element 47 obliquely toward the top is less pronounced here. As a result, the lower support element 47 on its lower side forms a counter running surface 49 which serves for rolling on one or a plurality of counterpressure rollers 73 of the carriage 7. Otherwise, the design of the upper part of the suspension part 4 is very similar to that of the suspension part 4 in FIG. 2.
[0107] The lower part of the suspension part 4 of FIG. 7, having the door leaf portion 42 and the bearing element 42, is likewise designed to be very similar to the lower part of the suspension part 4 of FIG. 2. In comparison to the embodiment of FIG. 2, the bearing element 43 and thus the running surface 44 are disposed to be somewhat higher above.
[0108] The carriage 7, which can be seen in FIG. 8, differs from that of FIG. 3 in particular in that the counterpressure roller 73 here is disposed so as to be offset somewhat farther to the inside, i.e. toward the roller 72. As a result, the counterpressure roller 73 bears on the counter running surface 49, or rolls on the latter, respectively, which herein is formed by the suspension part 4 instead of the component part 5, as mentioned. The rolling action of the counterpressure rollers 73 on the suspension part 4 instead of on the component part 5 has the advantage that noise emissions can be reduced as a result.
[0109] The component part 5 illustrated in FIG. 9 differs from that of the embodiment of FIGS. 1 to 5 only in the region of the connecting portion 51. The connecting portion 51 has a hanging element 52 that runs horizontally here and has a lower bearing face which on the side facing away from the suspension part 4 is delimited by an oblique face. The oblique face, which forms an undercut, extends from the lower bearing space toward the top at an acute angle.
[0110] FIG. 10 shows the component part 5 hung on the suspension part 4 and secured on the latter in a suspension assembly 2 assembled according to the intended use. The component part 5 by way of its hanging element 52 bears on the lower support element 47 of the suspension part 4, and is supported by the latter from below in a support point S1. As can be seen in the detailed view of FIG. 11, the hanging element 52 (as here) and/or the lower support element 47 can in each case have a local elevation, e.g. in the form of a material thickening, in the region of the support point S1, so as to define the position of the support point S2. The hanging element 52, by way of its free end, bears on the upper support element 48 from below, the latter supporting the hanging element 52 from above in a further support point S2, i.e. absorbing part of the weight of the component part 5 including the components attached thereto. As can moreover be seen in FIG. 10 and in particular in FIG. 11, the lower support element 47 and the hanging element 52 herein are hooked into one another in the region above the counter running surface 49, i.e. the two oblique faces formed by the lower support element 47 and by the hanging element 52 bear on one another.
[0111] Securing the component part 5 on the suspension part 4 can be seen when viewing FIGS. 10 to 12 in combination. One or a plurality of securing elements 55, which here are formed by loose groove blocks, serve this purpose. The securing elements 55 here are in each case disposed on the lower side of the component part 5, between the lower support element 47 of the suspension part 4 and a face of the component part 5 that extends perpendicularly downward. As a result, the groove blocks are thus disposed between the suspension part 4 and the component part 5. The positioning of the groove blocks on the lower side of the component part 5 makes it particularly easy for a technician to attach said groove blocks to the suspension assembly 2, and to subsequently activate them for securing even when a door leaf 3 and the drive 6 and further components have already been attached to the suspension assembly.
[0112] The securing elements 55, which are designed as groove blocks and can be readily seen in particular in FIG. 12, have an overall flat shape, and on their lower side have an engagement structure in the form of a Torx structure. The Torx structure serves to rotate the groove block by means of a tool, and defines a rotation axis of the groove block. An Allen key structure, a slot structure or any other structure may be provided instead of a Torx structure. The groove blocks have in each case two eccentric external faces disposed on opposite sides of the groove blocks. When the groove block is rotated by means of a tool, the eccentric external faces are in each case pressed increasingly against the suspension part 4, or the component part 5, respectively, as a result of which the oblique face of the hanging element 52 is drawn increasingly toward the oblique face of the lower support element 47 (see FIG. 10). In this way, the component part 5 and the suspension part 4 can be braced in a very simple yet efficient manner with the aid of the groove blocks, and said component part 5 is secured in terms of its position as a result and in particular secured against falling off. The groove blocks thus form bracing elements. Securing by means of groove blocks has proven particularly advantageous in particular when the construction surface, or the wall W, is uneven, which could lead to (minor) deformations of the suspension part 4 during assembling. As opposed to screws, groove blocks moreover have the advantage that the latter can be used at arbitrary locations and in arbitrary numbers along the profiled rails 4, 5.
[0113] In order to prevent the securing elements 55, or the groove blocks, from falling down when they have not yet been fully tightened, the groove blocks bear in each case peripherally on horizontal holding webs of the suspension part 4 and of the component part 5. If the grooves are correspondingly sized, the groove blocks in the untightened state can in this way even be held firmly on the suspension assembly 2 to some extent.
[0114] It goes without saying that the above invention is not limited to the present embodiments, and a multiplicity of variants are possible. In this way, the suspension part and the component part may also have other cross-sectional shapes, for example, and do not even have to be designed mandatorily as profiled rails. Instead of the drive, other components of the sliding door can also be attached to the component part. The drive 6 in this instance could be attached to another support part, or else for example directly to the suspension part, or be disposed at another location, for example in the region of the lower closing edge 33. A multiplicity of further variants are possible.
