Description

[Technical field]

[0001] The present invention relates to a suspension assembly for at least one leaf of a sliding door, to a sliding door having a suspension assembly of this type, and to a method for assembling a sliding door having a suspension assembly. [Background technology]

[0002] Sliding doors with at least one, and often two, displaceable leaves have been known for a long time. The leaf or leaves can be displaced in most cases perpendicular to the passage direction, so that for example a passage through a wall opening of a building can be opened or closed, respectively. In particular, automatic sliding doors are also known, in which the leaf or leaves do not have to be manually displaced for opening or closing, but this is done by a drive motor. In both cases, the sliding door can be provided with a presence sensor on both sides, so that the automatic opening of the sliding door is initiated as soon as a person approaches the sliding door.

[0003] In most of the sliding doors currently in use, the door or doors are in each case attached to a suspension part, for example in the form of a profile rail, which is rigidly attached to the wall above the wall opening and is used to suspend the door or doors. To allow the displacement of the door or doors, the suspension part usually has a horizontal running surface extending along the wall, on which the door or doors are supported by one or more carriages. In this case, the carriage or carriages are typically attached to the upper closing edge of the door. The door can be moved in the opening and / or closing direction along the running surface via rollers attached to the carriages. Guide means for achieving a guided displacement of the door are most often provided on the lower closing edge of the door. The guide means can be, for example, a guide block attached to the door and protruding into a guide rail provided on the floor.

[0004] The suspension part thus forms the connection between the sliding door or doors and the wall. If the sliding door is an automatic sliding door, it additionally has a drive motor, which is typically stationary in the region of the upper closing edge and is arranged, for example, connected to the carriage or carriages via a rotating belt in order to drive said carriage or carriages. To fasten the drive motor and / or further functional components, such as a control unit, the sliding door most often has a component part that is attached to the wall or suspension part above the door or doors. For ease of assembly and manufacturing, the component part is often attached to the suspension part in the prior art.

[0005] A co-integrated design of the suspension part and the component part, for example where one moulding forms the suspension part and the component part, is typically disadvantageous, especially in terms of assembly. As a result, the installation to be fixed to the wall becomes heavier. Furthermore, due to the additional space required, the component part makes it more difficult to suspend the sliding door or otherwise has to be compromised in this design embodiment of the component part that is expected to suspend the sliding door. Furthermore, the two-part aspect of the suspension part and the component part has the advantage that the assembly can be modular as a result, which potentially allows, for example, the retrofitting of a drive motor to a sliding door that was previously operated manually.

[0006] For the sake of available space and to allow for a simple connection between the drive belt and the carriage(s), the component parts of many sliding doors are arranged and designed in such a way that the drive motor and other components held in the component parts are located outside the carriage(s), i.e. in this case the carriage(s) is located between the wall and the drive motor.

[0007] For example, in the profile suspension for sliding doors shown in Patent Document 1, the rollers are supported on the running surface of a first profile and the linear motor is arranged in the area of ​​a second profile, which is attached to the first profile via a connecting element.

[0008] Patent document 2 discloses a suspension assembly having a base profile which is fixed to a wall and to which another profile is screwed, which on the one hand forms the running surface for the sliding door carriage and on the other hand serves to accommodate the linear drive.

[0009] US Patent No. 5,399,633 discloses a sliding door assembly in which a support profile, which establishes a connection to the wall, forms a running surface for the rollers of a carriage. A component part supporting the drive motor is screwed to the support profile.

[0010] US 6,313,933 discloses a three-part profile for mounting the carriage and further components of a sliding door assembly. A so-called transom profile serves as the connection to the wall and as a support surface for the rollers of the carriage. The support rollers mounted on the carriage are likewise supported on the transom profile. A closure profile is fastened to the transom profile, which likewise has a finishing profile attached to it. The three-profile part forms an interior that is used to accommodate a motor and further components. In this case, the motor is fixed to the transom profile via a retaining plate.

[0011] Prior art suspension assemblies for sliding doors are relatively complicated to manufacture, especially in assembly. Mounting the component parts together with the drive motor and other components is often difficult and time-consuming for technicians, especially due to their location above the door.

[0012] Assembly is further hindered if the carriage is provided with counterpressure elements, such as counterrollers, which support the door against the top so as to prevent it from pivoting in the passing direction. In this case, the door must be assembled with the carriage or carriages precisely in the hanging parts with a small margin for maneuvering, which is usually difficult for the technician due to the heavy weight of the door. [Prior art documents] [Patent documents]

[0013] [Patent Document 1] Spanish Patent Application Publication No. 2401861 [Patent Document 2] DE 102007041360 [Patent Document 3] European Patent Application Publication No. 3176354 [Patent Document 4] WO 99 / 40284 Summary of the Invention

[0014] The object of the present invention is to define a suspension assembly for at least one leaf of a sliding door, which is easy in terms of manufacture and assembly.

[0015] To achieve this object, a suspension assembly is proposed according to claim 1. Furthermore, a sliding door with such a suspension assembly is defined in claim 14. Furthermore, the invention relates to a method for assembling a sliding door with a suspension device according to claim 15. Further embodiments are defined in the dependent claims.

[0016] In the following, position and direction indications, e.g. upper, lower, vertical, horizontal, above, below, etc., in all cases refer to the sliding door, in particular to the suspension assembly assembled on the wall according to the intended use, where the suspension assembly is usually arranged above the door or doors with respect to the direction of gravity.

[0017] The present invention therefore relates to a suspension assembly for at least one leaf of a sliding door, comprising: A suspension part having a running surface and used for suspending at least one door so as to cooperate with a carriage supported on the running surface via a carriage attached to the door and displaceable to roll or slide along the running surface; a component part attached or attachable to the suspension part and used to hold a drive motor and / or another component; To enable a suspension assembly including:

[0018] The suspended part includes at least one lower support element and at least one upper support element, and the component part includes at least one hook element, via which the component part is hooked to the suspended part, such that the hook element is supported downwardly by the lower support element at a first support point and upwardly by the upper support element at a second support point, the first support point being disposed spaced apart between the second support point and a center of gravity of the component part including the component attached to the component part.

[0019] The assembly of sliding doors, in particular suspension assemblies, is significantly simplified in that the component parts can be hooked to the suspension parts as described above. The technician first fastens the suspension part to the wall, then hangs one or more doors on said suspension parts and finally hooks the component parts, preferably including the components attached to the component parts, to the suspension parts. Due to the lower and upper support elements and due to the fact that the hooking elements are supported at both support points, the hooking can be performed in a particularly simple manner, so that the position of the component parts is directly held on the suspension parts depending on the use. The technician does not have to support the weight of the component parts and at the same time does not have to establish, for example, a screw fastening between the component parts and the suspension parts in the process, but instead simply hooks the component parts to the suspension parts. For safety reasons, the component parts can also be finally additionally fixed to the suspension parts by means of fastening elements.

[0020] Also, assembly is simplified for the technician because the component part with the drive motor and / or other components do not have to be attached to the hanging part yet when the door is hung on the hanging part, resulting in less space constraints for hanging one or more doors on the hanging part.

[0021] A hanging part is used to connect, in particular to suspend, one or more doors to a wall. In this context, a wall is understood to be a stationary component, for example of a building. In this case, the wall to which the hanging part is fixed typically defines a sliding door, i.e. in particular a passage opening that is closed or opened by one or possibly several doors. To fix the hanging part to the wall, the hanging part may have corresponding fastening means, for example holes. However, the fastening of the hanging part to the wall may also take place indirectly, for example via an assembly rail fixed to the wall.

[0022] The running surface is preferably oriented upwards, i.e. in a direction extending against gravity, so that the carriage attached to the door is supported on the running surface. The weight of the door is thus absorbed at least partially, preferably to the extent of at least 50%, more preferably to the extent of at least 75%, most preferably to the extent of at least 90%, by the suspension parts via the running surface. The remaining weight of the door can be absorbed, for example, via the floor, in particular via a guide rail provided on the floor. One or more carriages, but preferably exactly two carriages, can be attached to the door, which carriages are supported on the running surface. In order to allow optimal guidance of the carriage or carriages, the running surface is preferably curved upwards or downwards, i.e. is designed convexly or concavely. In this case, the carriage has one or more running elements, respectively, which have a shape complementary to the running surface, i.e. are designed concavely or convexly. The one or more running elements are preferably rollers. In this way, the displacement of the door can be carried out with particularly low friction and noise. It is of course also possible for one or more running elements to be designed as sliding elements, so that when displacing the carriage correspondingly slides on the running surface.

[0023] The component parts are used to attach, in particular, electrical and / or mechanical components to the suspension assembly. The components may in particular be components of a power train and / or a door control unit. A power train component may in particular be a drive motor, which is used to automatically displace the door or doors along the running surface. Alternatively or additionally, the components attached to the component parts may be components of the power train or else gearboxes, drive wheels and / or force transmission elements, such as, for example, drive belts. The control units attached to the component parts may for example comprise a main power supply unit, a computer unit, a storage unit, one or more sensors, a movement detection unit and / or a transmission unit for communicating wirelessly or by wire with an external device. Any further functional units required for operating the door or doors, or otherwise required functional units, such as, for example, a locking device for locking the door or doors in the closed state or a Bowden cable for manual emergency unlocking, may also be attached to the component parts. For this purpose, the component parts preferably have corresponding attachment elements, such as, for example, holes, back engagement elements, assembly rails, etc.

[0024] The component part itself may form a cover for a component housed therein or behind, or may have a connecting structure to which a cover element in the form of a sheet metal cover plate can be attached.

[0025] The component parts are preferably designed to support at least 50% of the weight of the drive motor and / or other component. More preferably, the component parts are designed to support at least 75% and most preferably even exactly 100% of the weight of the drive motor and / or other component. The component parts are further preferably designed such that the drive motor and / or other component is attached to an underside of the respective component part.

[0026] In one particularly preferred embodiment, the lower support element and the upper support element are each formed by a protrusion protruding from the suspension part towards the component part, with the advantage that a hook element, preferably formed by a protrusion protruding from the component part towards the suspension part, can simply be inserted between the lower support element and the upper support element in order to hook the component part to the suspension part.

[0027] The supporting action of the hook element via the two support points can be considered as a physical lever, in that the first support point forms a fulcrum around which the component part can rotate via its hook element. The weight of the component part, including the component attached to it, brings about a rotational force, which is resisted by the upper support element at the second support point on the opposite side of the fulcrum. This means that the weight of the component side is absorbed by the upper support element, so that a force balance is established and the component part is in a stable position.

[0028] The first support points are preferably spaced apart from the second support points and from the center of gravity of the component part. More preferably, the first support points are each horizontally spaced apart from the second support points and from the center of gravity of the component part. The center of gravity is defined by the weight distribution of the component parts, including components attached to the component parts, such as drive motors and / or other components.

[0029] In one particularly preferred embodiment, the suspension part is designed as a profile rail. The profile rail can be designed in particular as a one-piece whole. The material of the suspension part is preferably metal, possibly a plastic material. The metal can be, for example, aluminum.

[0030] The component parts are also preferably designed as profile rails. They can also be designed in particular as a one-piece whole. The material of the component parts is also preferably metal, possibly a plastic material. In this case too, the metal can be, for example, aluminum.

[0031] Producing the suspension parts and / or component parts as profile rails is particularly simple and cost-effective. Furthermore, relatively lightweight profile rails can be produced.

[0032] The upper support element, and preferably also the lower support element, is preferably arranged above the running surface when the suspension assembly is assembled for its intended use, so that the component parts can be hooked to the suspension parts above the running surface, so that a displacement path can be left free along the running surface for one or more doors.

[0033] To prevent the door suspended on the suspension part from pivoting along the passageway direction, one or more counterpressure elements are advantageously attached to said door. The one or more counterpressure elements may in particular be provided on the carriage. The one or more counterpressure elements may in particular be counterpressure rollers which, when the door is displaced, roll on a counterrunning surface preferably provided on the suspension assembly. The counterrunning surface thus serves to come into contact with the counterpressure element attached to the door, in particular with the counterpressure roller attached to the door.

[0034] In some embodiments, this counter-running surface can be formed by a component part. This entails the advantage that the hanging of the door on the hanging part is significantly simplified, since for this only one or more running elements of the carriage need to be arranged on the running surface, without the additional simultaneous consideration of the correct positioning of the counter-pressure element with respect to the counter-running surface. As a result, the door can be hung on the hanging part, in particular also in a slightly inclined position, i.e. pivoted along the passage direction. When the door is hung, it can be vertically aligned on the basis of gravity, if it is not already vertically aligned by gravity. Then, when the component part is hung, the counter-pressure element or elements preferably come into contact with the counter-running surface.

[0035] In another embodiment, however, the counter running surface can instead be formed by a suspended part, which has the advantage that the amount of noise emissions during operation of the sliding door can be reduced.

[0036] The counter surface is preferably located between the first support point and the center of gravity of the component part. In one arrangement of the counter surface of this type, when the component part is hooked, the counter surface typically automatically contacts one or more counter pressure elements. As a result, assembly is made easier.

[0037] When the suspension assembly is assembled for its intended use, the suspension parts with the lower support elements extend outwardly towards the component parts not as far as the running surface or at most as far as the running surface.

[0038] If, when the suspension assembly is assembled for the intended use, the suspension part with its lower support element extends outwardly in the direction of the component parts not as far as the running surface or at most as far as the running surface, it becomes particularly simple for the technician to hang the door on the suspension part, i.e. when the door is attached to the suspension part, the lower support element does not or only to a significantly lesser extent interferes with the door and the components optionally attached to the door, for example by arranging one or more carriages on the running surface of the suspension part. In this case, the space above the running surface on the side of the suspension part facing the mounting of the component parts is typically free, making the hanging of the door on the suspension part particularly simple. In some cases, even the space immediately below the running surface is free.

[0039] In this case, when the suspension assembly is assembled for the intended use, the suspension part extends with the lower support element in the direction of the component part in the same extent as the running surface extends with its outermost end of the lower support element in the direction of the component part, i.e. usually horizontally in the direction of the outside, in the same extent as the running surface extends with its circumferential surface facing the component part. When the suspension assembly is assembled for the intended use, the parts of the suspension part that do not contribute to the absorption of the load occurring at the first support point are typically not considered to be associated with the lower support element. When the suspension assembly is assembled for the intended use, the suspension part extends with the lower support path, for example in particular outwardly in the direction of the component part to the first support point, not as far as the running surface or at most as far as the running surface.

[0040] Furthermore, the suspension assembly preferably comprises a fastening element for fastening the component part to the suspended part, which may for example be one or more screws which are for example screwed through the component part into the suspended part or fastened to the suspended part by means of a nut, in order to prevent the component part from coming off from the suspended part, for example due to external mechanical influences.

[0041] In one particularly preferred embodiment, however, the fixing element is at least one fastening element that is arranged between the suspension part and the component part and is designed to fasten the suspension part and the component part to one another. The fastening element can therefore in particular be fastened between, for example, two mutually facing surfaces of the suspension part and the component part, whereby the parts are pressed away from one another by the fastening element. Advantageously, this results in the suspension part and the component part being pressed in a different location as well, preferably in the region of the hook element, and thus being fastened to one another, whereby a stronger bond is produced between the suspension part and the component part. By using a fastening element that is arranged between the suspension part and the component part, the component part can be fastened to the suspension part in a particularly simple manner.

[0042] For fastening the two components together, fastening elements are preferably arranged on the side of at least one of the suspension part and the component part facing the door, for example typically on the underside, such that after the component part has been hooked onto the suspension part, good accessibility to the fastening elements results in particularly easy fastening.

[0043] The clamping element preferably has at least one eccentric running surface, which can be gradually pressed against the suspended part and / or the component part by rotating the clamping element. The eccentric running surface allows a particularly simple but efficient clamping. The clamping element advantageously has a first eccentric running surface, which can be gradually pressed against the suspended part by rotating the clamping element, and a second eccentric running surface, which can be gradually pressed against the component part by rotating the clamping element in the same direction.

[0044] To facilitate rotation of the fastening element with a tool, the fastening element may have an engagement structure, such as an Allen key structure or a Torx structure.

[0045] The clamping element can preferably be pressed against the suspension part and the component part simultaneously by rotation, so that clamping can be carried out particularly efficiently.

[0046] In one particularly preferred embodiment, the fastening element is a groove block which is held in a groove of the suspension part and / or in a groove of the component part, preferably such that at least one groove is dimensioned in such a way that the groove block can be inserted into the groove with little effort in terms of force, but is reliably held in the groove after insertion, even when the groove block does not yet fasten the suspension part and the component part to one another.

[0047] When the suspension assembly is assembled according to the intended use, the component part is suspended from the suspension part in a particularly stable manner if the second support point is arranged at the same height as the first support point or below the first support point.

[0048] When the suspension assembly is assembled for its intended use, it is particularly easy for the technician to hook up the component parts if the lower support elements extend slightly obliquely upwards in the direction of the component parts, in which case the technician can simply enable the hook elements to slide along the upper surface of the lower support elements in order to hook up the component parts, which simplifies assembly.

[0049] The hook element and the upper support element each preferably form a hook, which are designed to hook-like engage with each other to ensure a connection between the suspension part and the component part when the suspension assembly is assembled for its intended use, and as a result of the hook-like engagement with each other, it is possible to prevent the component part from falling off the suspension part, for example due to unintended mechanical influences.

[0050] The present invention further relates to a sliding door having at least one door and a hanging assembly designed according to the above-mentioned embodiments for hanging the door on a wall.

[0051] The invention furthermore relates to a method for assembling a sliding door with a suspension assembly, which can be particularly preferably designed as described above, the suspension assembly comprising at least one suspension part with a running surface and a component part, the method comprising at least the following steps: -Attach the hanging parts to the wall, -Suspending the door on the suspension parts so that the carriage attached to the door is supported on the running surface; Includes.

[0052] The hanging part includes at least one lower support element and at least one upper support element, and the component part includes at least one hook element, and after hanging the door on the hanging part, the component part is hooked to the hanging part via the hook element such that the hook element is supported downwardly by the lower support element at a first support point and upwardly by the upper support element at a second support point, in which the first support point is disposed spaced between the second support point and the center of gravity of the component part.

[0053] When the door is hung on a hanging part, the hanging part is preferably already attached to the wall.

[0054] Preferably, the drive motor and / or another component is attached to the component part before the component part is hooked to the suspension part, although the drive motor and / or another component may possibly only be attached to the component part once the component part has already been hooked to the suspension part.

[0055] After hanging the component part on the suspension part, the component part is preferably fixed to the suspension part by means of a fixing element, which can be achieved for example by screwing the two parts together.

[0056] Furthermore, after the component part is hooked onto the hanging part, a drive motor attached to the component part is preferably connected to the door via a force transmission element, such as, for example, a drive belt. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0058] In figures 1 to 12 various suspension assemblies 2 according to the invention for a sliding door 1 are shown. Identical or functionally equivalent elements of the different embodiments are in the following provided with the same reference signs in each case.

[0059] In Fig. 1 a two-leaf sliding door 1 is shown, assembled according to the intended use, having two leaves 3 for closing a passage opening in a wall W, which leaves 3 are displaceable along a closing direction indicated by an arrow. In this case, the two leaves 3 are displaceable relative to one another until the two main closing edges 31 of the leaves 3 bear against one another. To open the sliding door 1, the two leaves 3 are displaceable in a direction opposite to the direction of the arrows, so as to move away from one another. In this case, the closing direction extends perpendicularly to the door passage direction. In both cases, sealing means may be provided along the main closing edges 31 for sealing the leaves 3 against one another in the closed state of the sliding door 1.

[0060] To allow the door 3 to be displaced, the door 3 is displaceably suspended from a wall W by a suspension assembly 2. The suspension assembly 2 is attached to the wall W so as to be fixed above the passage opening. The suspension assembly 2 has a longitudinal extension length extending horizontally, and in the longitudinal direction the suspension assembly 2 extends parallel to a floor B, which defines at its lower part the passage opening closed by the sliding door 1.

[0061] Each door 3 has an upper closing edge 32 to which is attached one or more carriages 7, not shown in FIG. 1 but visible in FIGS. 3 and 5, which are used to suspend each door 3 on the suspension assembly 2. Each lower closing edge 33 of the door 3 extends directly along the floor B. To achieve a guided displacement of the door 3, first guide means for guiding the door 3 are preferably provided on the lower closing edge 33, which interact with second guide means provided on the floor B. The first guide means may for example be one or more guide blocks which are provided on the floor B and engage in an upwardly opening guide rail. The guide rail is preferably recessed in the floor B.

[0062] Next, a first preferred embodiment of a suspension assembly 2 according to the present invention, which can be used for example for the sliding door 1 shown in Fig. 1, will be described with reference to Figs. 2 to 5. However, the suspension assembly 2 shown in Figs. 2 to 5 can also be used for other sliding doors 1, for example, a sliding door with one door or a sliding door with three or more displaceable doors 3.

[0063] To fix the suspension assembly 2 to the wall W, the suspension assembly comprises a suspension part 4, which in Fig. 2 is shown alone attached to the wall W. The suspension part 4 is a profile rail in this exemplary embodiment, i.e. the suspension part 4 has a uniform cross section in terms of area and shape along its entire longitudinal extension. The cross section of the suspension part 4 can be easily seen in Fig. 2, which shows the front end of the profile rail.

[0064] 2, the hanging part 4 has a wall 41 which extends vertically in cross section, by means of which the hanging part 4 is supported on a wall W. The wall 41 is provided with fastening means, such as holes or recesses provided with back engaging elements, for example, for fastening the hanging part 4 to the wall W, in particular for mounting the hanging part 4 on the wall W.

[0065] From the wall part 41, the door part 42 extends, in cross section, at the lower end of the wall part 41, approximately vertically from the wall W towards the front in the passage direction. The door part 42 serves to hold, in particular to suspend, one or more doors 3. For this purpose, the door part 42 has a free end forming a support element 43 which serves to support one or more carriages 7 attached to the door 3. The support element 43 is here covered by a cover 45 which forms a running surface 44. On the running surface 44, one or more carriages 7 are supported in the assembled state according to the intended use, and the running surface 44 is here curved convexly upwards, so that the carriages 7 can be displaced along the running surface 44 in the longitudinal direction of the suspension part 4.

[0066] As in the present exemplary embodiment, recesses, guide rails, screw holes etc. may be formed on the underside of the door part 42 for attaching various components of the sliding door, such as sealing means or sensors, to the hanging part 4.

[0067] The component part 46 extends from the upper end of the wall part 41 in a cross-sectional view shown in FIG. 2, so as to be approximately vertical from the wall W toward the front in the passage direction. The component part 46 has a free end that extends slightly obliquely upwards and forms a lower support element 47. As can be easily seen in FIG. 2, the lower support element 47 does not extend horizontally outward from the running surface 44. As a result, there is space for the lower support element 47 to suspend the door from the running surface 44 without interfering with the door and in particular the carriage attached to the door. Above the starting point from which the lower support element 47 extends obliquely upwards, the component part 46 forms an upper support element 48 in the form of a protrusion that extends outward perpendicularly to 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 each have a hook-shaped end at their free end. In the lower support element 47 the hooks extend upwards, in the upper support element 48 the hooks extend downwards. The component part 46 serves via the two support elements 47 and 48 to hold a component part 5 (see Figures 4 and 5) to which a drive motor 61 and further mechanical or electrical components are attached.

[0068] Due to the component part 46, the wall part 41 and the door part 42 the suspension part 4 has a C-shaped design in cross section.

[0069] FIG. 3 shows the same hanging part 4 as in FIG. 2, mounted on a wall W, but with a carriage 7 hung on the hanging part 4. The carriage 7 comprises at least one roller 72, via which the carriage 7 is supported on the running surface 44 of the hanging part 4. The roller 72 has a radially outer surface that is designed concavely and is designed complementary to the upwardly convexly curved running surface 44, so that the carriage 7 is guided during its displacement along the running surface 44. The rolling of the roller 72 on the running surface 44 is effected in a particularly quiet manner by means of a cover 45, which may also be omitted in a further embodiment. The cover 45 is preferably manufactured from a plastic material.

[0070] The roller or rollers 72 are attached to a main support 75 of the carriage 7, on which they are freely rotatable, the main support 75 extending vertically in cross section. At the lower end of the main support 75 a connecting element 71 is attached which is used to fasten the door 3. The connecting element 71 is normally attached to the upper closing edge 32 of the door 3. For illustrative reasons, the door 3 is not shown in Figures 3 and 5. The main support 75 is advantageously height adjustable, so that the distance between the rollers 72 and the connecting element 71 can be adjusted within a given range.

[0071] Furthermore, a counter pressure roller 73 is rotatably attached to the main support part 75 of the carriage 7. The function of the counter pressure roller 73 will be described later with reference to Figure 5, but the counter pressure roller 73 is arranged on the same side of the main support part 75 as the roller 72. However, as can be easily seen in Figure 3, the counter pressure roller 73 is arranged so as to be slightly offset from the suspended part 4. Furthermore, the counter pressure roller 73 is arranged so as to be slightly higher than the roller 72 on the main support part 75.

[0072] On the side of the main support 75 facing away from the roller 72 and the counterpressure roller 73, i.e. facing away from the hanging part 4, a clip 74 is attached to the main support 75 and extends perpendicularly outwards from the main support 75. In the intended assembled state, the clip 74 interacts with a force transmission element, for example a drive belt connected to a drive motor, in order to automate the displacement of the door 3.

[0073] Figure 4 shows the component part 5 with the drive 6 mounted thereon. Figure 4 shows a side view of one end face of the component part 5 designed as a profile rail.

[0074] The component part 5 has a connection part 51, which serves to suspend the component part 5 on the suspension part 4 during the assembly of the suspension assembly. The connection part 51 extends along an approximately horizontal direction and, in the assembled state for the intended use, extends towards the suspension part 4. The connection part 51 has a free end which extends slightly obliquely downwards towards the suspension part 4 and forms a hook element 52. At its outer end, the hook element 52 forms a hook-shaped end, whereby the hook extends slightly upwards. Furthermore, the connection part 51 forms on its underside a flat counter-running surface 53, which serves to come into contact with and roll on a counter pressure roller 73 attached to the carriage 7.

[0075] The connection part 51 transitions into an assembly part 54, which extends outwardly along the horizontal direction, on the side opposite the suspension part 4. On the underside of the assembly part 54, various mounting elements, such as holes, back engagement elements, assembly rails, etc., are formed. These mounting elements are used to mount the most diverse components, such as, in particular, the drive unit 6, to the suspension assembly 2. However, any further components may also be mounted on the assembly part 54, such as, for example, control elements, sensors, a main power supply unit, a movement detection unit and / or a transmission unit for communicating wirelessly or by wire with an external device.

[0076] The drive 6 shown in Fig. 4 comprises a drive motor 61 and an angle gearbox 62 connected to the drive motor 61. A drive wheel 63, used to drive a drive belt (not shown), is attached to the gearbox 62 via a shaft. In the assembled state according to the intended use, the clips 74 attached to the carriage or carriages 7 are supported by elements of the drive belt extending horizontally along the upper closing edge 32, so that they are entrained by the drive belt when it moves, so that the sliding door 1 opens and closes, respectively. All components of the drive 6 are attached from below to the assembly part 54 of the component part 5, for example by screwing to the assembly part 54.

[0077] In Fig. 5, the suspension assembly 2 is shown in an assembled state according to the intended use. The component part 5 is hooked via its hook element 52 to the component part 46 of the suspension part 4, which is mounted above the door passage opening in the wall W. In this case, the hook element 52 of the component part 5 protrudes into the intermediate space formed by the lower support element 47 and the upper support element 48. The lower support element 47 extends slightly upwards towards its free end, and the hook element 52 extends slightly downwards towards its free end, so that, as can be seen in Fig. 5, the lower support element 47 and the hook element 52 extend parallel to each other in the hooked state.

[0078] As can be further seen in Fig. 5, in the hung state, the component part 4 is supported from below at the first support point S1 by the lower support element 47 and from above at the second support point S2 by the upper support element 48. The center of gravity SP of the unit including the component part 4, the drive motor 61 and the further components, in particular the gearbox 62 and the drive wheel 63, is located approximately in the position shown in Fig. 5 and is thus significantly spaced horizontally outward from the first support point S1. In this way, the first support point S1 is arranged horizontally spaced 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 component part 5.

[0079] The component part 5 is therefore supported from below at the first support point S1 by the lower support element 47. Due to gravity, the component part 5 is pulled at its centre of gravity SP towards the floor B. However, this force acting towards the floor B is absorbed at the second support point S2 by the upper support element 48 on the side located opposite to the first support point S1, so that the component part 5 has a globally stable position.

[0080] An inadvertent withdrawal of the hooking element 52 of the component part 5 from the component part 46 of the suspension part is prevented by two interlocking hooks formed at the respective free ends of the upper support element 48 and of the hooking element 52. However, once the component part 5 has been hooked onto the suspension part 4, it is advisable for safety reasons to fasten the two parts to one another by means of fastening elements. For this purpose, the component part 5 and the suspension part 4 can in particular be screwed together in suitable positions.

[0081] 5, the counter pressure roller 72 mounted on the carriage 7 is arranged directly below the counter running surface 53 in the hooked state of the component part 5 or even contacts the counter running surface 53. As a result, the door 3 mounted on the carriage 7 can be prevented from pivoting along the passage direction. The counter pressure roller 72, which can be designed as a counter pressure sliding element in a further embodiment, also prevents the door 3 from being detached from the suspension part 4, in particular in the fully assembled state of the sliding door 1.

[0082] The method for assembling the sliding door 1 with the suspension assembly designed according to Figs. 2-5 is derived from the sequence of Figs.

[0083] In a first step, the suspension part 4 is fixed to the wall W above the passage opening (FIG. 2). In a second step, the door or doors 3 are hung on the suspension part 4 (FIG. 3). For this, the carriage or carriages 7 attached to the door 3 are placed on the running surface 44 of the suspension part 4 via the rollers 72 of the carriage 7. In this case, the suspension part 4 is not yet fitted with the component parts 5, and for this reason there is free space above the running surface 44, so that the suspension of the door or doors 3 on the suspension part 4 is particularly simple. During suspension, the space can also be utilized, in particular in the area of ​​the counterpressure rollers 73. Then, in the next step, the component part 5 (FIG. 4), with the drive motor 61 and the further components 62, 63 preferably already attached thereto, is hooked on the suspension part 4 (FIG. 5). For this, the component part 5 with the hooking element 52 in front must be easily introduced into the space between the two support elements 47, 48 of the component part 46. For this purpose, the design of the hook element 52 on the one hand and the upper support element 47 on the other hand allows the hook element 52 to be simply placed on the lower support element 47 and then advanced diagonally downwards along the lower support element 47 up to a detent. As a result, the component part 5 is hooked to the suspended part 4 in a stable position. For safety reasons, it is then also advisable to fasten the component part 5 to the suspended part 4 by means of one or more fixing elements 55. As a final step, a drive belt is then attached to the drive wheel 63, which can then be connected to the clip 74 of the carriage or carriages 7.

[0084] At its outer end facing away from the suspended part 4, the component part 5 may have one or more connection structures, by means of which a cover element, for example in the form of a sheet metal cover plate, can be attached. The sheet metal cover plate or cover plates can be attached to the component part 5 at the end of the assembly method, i.e. after the drive wheels 63 have been connected to the clips 74 via the force transmission elements.

[0085] Figure 6 shows a suspension assembly according to another embodiment, which is also according to the invention. The embodiment shown in Figure 6 differs from the embodiment shown in Figures 2 to 5 only in the design of the component part 46 of the suspension part 4 and the connection part 51 of the component part 5.

[0086] In the embodiment shown in FIG. 6, the component part 46 of the suspension part 4 is formed by a simple web extending vertically outward from the wall W and having at its free end a protrusion projecting slightly upwards, thereby forming a hook-shaped termination.

[0087] The hook element 52 of the connection part 51 is formed in one piece by two horizontal webs running parallel to one another, the lower web extending slightly further towards the hanging part 4 than the upper web. At its free end the upper web has a projection which projects slightly downwards, thus forming a hook-shaped termination.

[0088] To hook the component part 5, as shown in FIG. 6, the component part 5 is hooked to the suspension part 4 in such a way that the horizontally projecting web of the component part 46 is pushed into the intermediate space defined by the two parallel webs of the hooking elements 52 of the connection part 51. The free end of the web formed by the component part 46 supports the component part 5 from below at the first support point S1 in the process. At the same time, at a distance therefrom, the component part 46 supports the component part 5 from above at the second support point S2. In this way, the web formed by the component part 46 here simultaneously forms a lower support element 47 (in the region of its free end) and an upper support element 48 (in the region between the free end and the wall part 41). However, the positions of the first and second support points S1 and S2 as well as the position of the center of gravity SP of the component part 5 including the drive motor 61 and the further component attached to the drive motor 61 are the same as in the embodiment shown in FIG. 5.

[0089] Furthermore, FIG. 6 shows a fixing element 55 in the form of a screw-nut fastening means between the component part 5 and the suspension part 4 .

[0090] In figures 7 to 12, another embodiment of the suspension assembly 2 according to the invention is shown. As can be seen in figure 7, the lower support element 47 here extends somewhat further outwards in the direction of the component part 5, but still does not extend beyond the running surface 44. In the region of its free end, the lower support element 47 forms an upwardly directed hook, which on the side facing away from the component part 5 has an inclined surface. This inclined surface forms an undercut. In comparison with the embodiment shown in figures 1 to 5, the lower support element 47 extends somewhat further outwards in the horizontal direction from the wall 41, i.e. here the inclination of the lower support element 47 obliquely upwards is less pronounced. As a result, the lower support element 47 forms on its underside a counter-running surface 49, which serves for rolling one or more counter-pressure rollers 73 of the carriage 7. In other respects, the design of the upper part of this suspension part 4 is quite similar to the design of the upper part of the suspension part 4 shown in figure 2.

[0091] The lower part of the suspension part 4 shown in Fig. 7 with the door 42 and the support element 42 is also designed very similarly to the lower part of the suspension part 4 shown in Fig. 2. Compared to the embodiment shown in Fig. 2, the support element 43 and thus the running surface 44 are arranged slightly higher upwards.

[0092] The carriage 7 which can be seen in Fig. 8 differs from the carriage 7 shown in Fig. 3 in particular in that the counter pressure roller 73 is now arranged slightly further inwards, i.e. offset towards the roller 72. As a result, the counter pressure roller 73 either contacts or rolls on the counter running surface 49, respectively, which is now formed by the suspension part 4 instead of the component part 5, as described above. The rolling movement of the counter pressure roller 73 on the suspension part 4 instead of the component part 5 has the advantage that noise emissions can be reduced as a result.

[0093] The component part 5 shown in Figure 9 differs from the embodiment shown in Figures 1 to 5 only in the region of the connection part 51. Here, the connection part 51 has a horizontally extending hook element 52 and, on the side facing away from the suspension part 4, has a lower support surface which is defined by an inclined surface. This inclined surface, which forms an undercut, runs at an acute angle from the lower support space towards the top.

[0094] In Fig. 10, a component part 5 is shown, which is hooked and fixed to the suspension part 4 in the suspension assembly 2 assembled for the intended use. The component part 5 rests on the lower support element 47 of the suspension part 4 via its hook element 52 and is supported by the lower support element 47 of the suspension part 4 from below at a support point S1. As can be seen in the detailed view of Fig. 11, the hook element 52 (in this case) and / or the lower support element 47, respectively, may have a localized protuberance, for example in the form of a material thickening, in the region of the support point S1, which defines the position of the support point S2. The hook element 52 presses via its free end against the upper support element 48 from below, which in turn presses against the hook element 52 from above at another support point S2, i.e. absorbing part of the weight of the component part 5 including the component attached to it. As can further be seen in Figure 10, and in particular in Figure 11, here the lower support element 47 and the hook element 52 engage with each other in a hook-like manner in the area above the counter running surface 49, i.e. the two inclined surfaces formed by the lower support element 47 and the hook element 52 engage with each other.

[0095] The fixing of the component part 5 in the suspension part 4 can be seen in the combined view of Figures 10 to 12. For this purpose, one or more fixing elements 55 are used, which are here formed by loose groove blocks. In this case, the fixing elements 55 are respectively arranged on the underside of the component part 5, between the lower support element 47 of the suspension part 4 and the vertically downwardly extending surface of the component part 5. As a result, the groove block is therefore arranged between the suspension part 4 and the component part 5. The arrangement of the groove block on the underside of the component part 5 makes it particularly easy for a technician to attach it to the suspension assembly 2 and then actuate and fix it, even when the door 3, the drive 6 and further components have already been attached to the suspension assembly.

[0096] The fastening element 55, designed as a groove block, which can be easily seen in particular in FIG. 12, has an overall flat shape and has an engagement structure in the form of a Torx structure on its underside. The Torx structure is used to rotate the groove block with a tool and defines the axis of rotation of the groove block. Instead of the Torx structure, an Allen key structure, a slot structure or any other structure can also be provided. The groove blocks each have two eccentric surfaces arranged on opposite sides of the groove block. When the groove block is rotated with a tool, the eccentric surfaces are gradually pressed against the suspension part 4 or the component part 5, respectively, so that the inclined surface of the hook element 52 is gradually drawn towards the inclined surface of the lower support element 47 (see FIG. 10). In this way, the component part 5 and the suspension part 4 can be fastened very simply and efficiently by the groove block, so that the component part 5 is fixed with respect to its position and in particular fixed against falling. The groove blocks therefore form a fastening element. Fastening by means of groove blocks has proven to be particularly advantageous, in particular when the surface or wall W of the structure is not flat, which may lead to (small) deformations of the suspended part 4 during assembly. In contrast to screws, groove blocks have the further advantage that they can be used at any position along the profile rails 4, 5 and in any number.

[0097] To prevent the fixing element 55 or the groove block from falling off when not yet fully fastened, the groove block is supported in the circumferential direction on horizontal retaining webs of the suspension part 4 and the component part 5, respectively. In this way, the groove block can even be held relatively firmly in the suspension assembly 2, even when not fastened, if the grooves are correspondingly dimensioned.

[0098] Needless to say, the invention is not limited to the present embodiment, and numerous variants are possible. Thus, the suspension part and the component part may, for example, have another cross-sectional shape and do not even necessarily have to be designed as a profile rail. Instead of the drive, another component of the sliding door may also be attached to the component part. In this case, the drive 6 may be attached to a separate support or else, for example, directly to the suspension part, or may be arranged elsewhere, for example in the region of the lower closing edge 33. Numerous further variants are possible. [Explanation of symbols]
