Description

Carriage for slidably supporting a load and partition system

The present invention relates to a carriage for slidably supporting a load, in particular a door, a wing or a curtain on a guide profile, with a first section on which two castors are rotatably mounted and a second section suitable for connection to the load , wherein the first section and the second section are rotatably connected to one another via a connecting bearing about a vertical axis.

The invention further comprises a partition system with wall elements which are slidably mounted in a guide device which comprises at least one guide profile.

A carriage and a partition system of the type mentioned are disclosed in DE 196 20 045 C1. The Fig.1 of the accompanying drawings is taken from this document and shows a wall element 10, which with a carriage 12 on two horizontally juxtaposed guide profiles 14th a guide device 16 is slidably mounted. The carriage 12 comprises a first section 18 on which a concave roller 22 and a cylindrical roller 24 are rotatably mounted. Furthermore, the carriage 12 comprises a second section 26, which is formed by a suspension rod and which is rotatably connected to the first section 18 via a connecting bearing 28 about a vertical axis.

On the first section 18 of the carriage 12, two guide rollers 30 are also arranged one behind the other in the running direction, which run along in a guide groove 32 of the guide device 16. The guide rollers 30 cause the carriage 12 to run straight and safely. Since the first section 18 of the carriage 12 can be rotated relative to the wall element 10 via the connecting bearing 28, ^" without the guide rollers 30, the carriage 12 would have a tendency to move when the wall element 10 is moved In the worst case, this could lead to the concave roller 22 jumping off the guide profile 14, but at least leading to a restless, jerky travel of the carriage on the guide profiles 14.

While the carriage 10 from the prior art has good running behavior on straight routes due to its guide rollers 30, problems arise when the carriage is driven around curves. These problems are explained below with reference to the schematic diagrams shown in FIGS. 2 and 3.

2 and 3 schematically show a top view of the guide profile 14 on the left in FIG. 1, which has a straight section which is arranged to the right of the dash-dotted line 34 and a curved section which is to the left of the dash-dotted line Line 34 is arranged. Furthermore, in the top view of FIG. 2, the concave roller 22, which is on the guide tion profile 14 rests, and the two guide rollers 30 arranged one behind the other in the direction of travel are shown, which are guided in the guide channel 32.

2 shows a snapshot in which the carriage 10 (of which only the concave roller 22 and the guide rollers 30 are shown for the sake of clarity) moves to the left. At this time, the leading (i.e., left) guide roller 30 just enters the curved portion of the guide device 16. In the curved section of the guide device 16 shown in FIG. 2, the horizontal distance between the side walls of the guide channel 32 and the guide profile 14 is the same as in the straight section of the guide device 16. Therefore, the leading guide roller 30 lies on both of them when entering the curved area Side walls of the guide trough 32 and would thus be optimally guided.

3 shows the same components of the carriage 12 in a later snapshot, in which the trailing guide roller 30 has just entered the straight section into the curved section of the guide device 16. As can be seen in FIG. 3, the concave roller 22 now lies on a curved section of the guide profile 14. Since the running surface of the concave roller 22 is adapted to the cross-sectional area of the guide profile 14, the concave roller 22 is oriented tangentially to the guide profile 14 as shown in FIG.

A problem with the conventional carriage 12 is that the curve curvature of the guide profile 14 cannot be particularly pronounced because the concave roller 22 would otherwise jam with the edge portions of its tread on the guide profile 14. In practice, a compromise must be found between a relatively small curvature of the guide profile 14 on the one hand and the recess depth of the tread of the concave roller 22 on the other. Such a compromise is usually unsatisfactory because, on the one hand, there are often relatively tight curves in the guide Device 16 must be realized, but on the other hand, it is difficult to dispense with a relatively pronounced concave profile of the concave roller 22, since this improves the running properties and prevents the carriage 12 from jumping off the track.

Another problem is that the combination of guide rollers 30 and guide channel 32 arranged one behind the other is not suitable for guiding the carriage 12 in a curve. It is clear from FIG. 3 that the shape of the guide device 16 shown in FIG. 2, which is obvious at first glance, in which the horizontal distance between the guide profile 14 and the side surfaces of the guide groove 32 is as large in the curve as in the straight one Section, is not suitable since the vertical axes 30a and 30b of the leading or trailing guide roller 30 no longer stand vertically on the guide profile 14 when passing through the curve in the plan view of FIG. 3, but are shifted outward. This means that the outer side wall of the guide trough 32 would have to be guided further outwards as shown in FIGS. 2 and 3, as indicated by the broken line 32 ', so that the guide rollers 30 have space in the guide trough 32. Likewise, the inner side edge of the guide trough 32 would have to be displaced outwards so that the guide rollers 30 are also guided inside when the curve is passed.

However, it is in principle impossible to design the guide trough 32 such that both guide rollers 30 are guided at both times on the inner and on the outer side edge of the guide trough 32 when passing through the curve. To explain this, reference is once again made to the snapshot of FIG. 2, in which the leading guide roller 30 has just entered the curved section of the guide device 16 from the straight section. Since the concave roller 22 is still in the straight section (ie to the right of the dash-dotted line 34) of the guide device 16, the leading guide roller 30 is guided inside and outside when passing from the straight section into the curved section of the guide device 16 from the side edges of the guide trough 32.

However, as shown in FIG. 3, if the trailing guide roller 30 passes from the straight into the curved region of the guide device 16, the concave roller 22 is already in the curved region, so that the carriage 12 is already slightly rotated. This has the consequence that the vertical axis of rotation 30b of the trailing guide roller 30 is no longer above the guide profile 14, but is displaced horizontally outwards relative to this. So that the trailing guide roller 30 can even enter the curved area, the outer side edge of the guide groove 32 at the transition area between the straight and the curved section of the guide device 16 must already be exposed to the outside, as modified by the one shown in dashed lines in FIG Guide groove 32 'is indicated. However, the modified guide trough 32 ′, in turn, cannot guide the leading guide roller 30 on the outside when entering the curved region of the guide device 16, as is clear from FIG. 2.

From the discussion above it can be seen that the guide channel 32 can in principle not be designed so that both guide rails 30 are continuously guided inside and outside when passing through the curve. The result of this is that the carriage 12 is not completely guided when cornering and therefore cannot move smoothly and even around tight curves.

Another carriage is disclosed in CH 634 623 A5. The present invention has for its object to provide a carriage for slidably supporting a load that can travel safely and smoothly around curves.

This object is achieved in a carriage of the type mentioned in that the two rollers viewed in the direction of the carriage next to each other and are arranged in a V-shape to each other so that they can rest together on the same guide profile in the area of the top of the "V".

Due to the "V" position of the rollers, the carriage is safely guided on the guide profile, regardless of whether the guide profile is straight or curved. The castors act both as load-bearing and as leading roles.

Since the rollers lie on the side of the guide profile due to their "V" position, they prevent the carriage from jumping off the guide profile and always align the first section of the carriage tangentially to the guide profile. Unlike a vertical roller rotatably mounted about a vertical axis, the pair of V-shaped rollers of the solution according to the invention does not tend to move transversely to the direction of travel when the carriage is displaced. Therefore, no additional guide rollers such as the guide rollers 32 from the prior art are required in the carriage according to the invention, as a result of which the carriage is simpler and cheaper to construct than known carriages.

In addition, the inclined rollers of the carriage according to the invention can be used to make much tighter turns than a vertically arranged roller with a concave tread, for example the concave one Prior art roller 22 is permitted. This also applies if the rollers of the carriage according to the invention also have concave treads.

The axis of rotation of the connection bearing preferably runs through between the support locations of the two rollers when the carriage is placed on the guide profile. This has the consequence that a slight rotatability of the carriage on the guide profile about a vertical axis does not lead to a horizontal mobility of the load.

A fastening element for fastening the load is preferably provided on the second section, the connection point with the load of which is arranged essentially vertically below (in the case of a suspended load) or vertically above (in the case of a load on the carriage) of the intermediate region between the support points of the two rollers on the guide profile , This prevents the load from applying torque to the carriage. In an advantageous further development, the fastening element is formed by a vertical bolt, the longitudinal axis of which runs between the support points of the two rollers on the guide profile. This pin is preferably in turn part of the connection bearing.

The running surfaces of the two rollers are preferably adapted to the cross section of the guide profile in such a way that they form a support line with the guide profile. As a result, the carriage is guided particularly well on the guide profile. In an advantageous development, the two rollers together grip the guide profile. This prevents the carriage from jumping off the guide profile during operation. The problems described above in the function of conventional carriages have a negative impact on the function of conventional partition systems, in which such carriages are used for the displaceable mounting of partition walls. In conventional partition systems, problems often arise when the partition walls in the guide device have to be driven around curves. Furthermore, problems often arise in conventional partition wall systems if branches are provided in the guide device. Such branches in the guide device are required in particular if a plurality of wall elements which can be arranged one behind the other along a straight section of the guide device, for example in order to divide a space, are to be arranged parallel to one another for storage or parking.

A guide device with branching, which is suitable for parking wall elements, is also described in the above-mentioned DE 196 20 045 C1. Other partition systems with branches in the guide device are known for example from DE 690 22 643 T2, DE 31 48 464 C3 and DE 36 14 627 C2. In all of these known partition systems, the branches are implemented in a relatively complex manner, as a rule using a large number of guide elements such as guide rollers and guide flanges. Nevertheless, despite the complex technology, most of the known partition wall systems do not work very reliably, especially when there are branches in the guide device. Known partition wall systems are usually difficult to handle on branches and are easily damaged, in particular by unskilled or negligent personnel, if their wall elements are moved over branches.

According to a second aspect, the invention is based on the object of further developing a partition system of the type mentioned at the outset in such a way that the wall elements can easily be moved around curves or driven.

This object is achieved in a partition system of the type mentioned in that two of the carriages according to the invention or developed above are arranged one behind the other on the wall elements in the direction of displacement.

The improved running behavior of the carriages according to the invention is directly transferred to the simpler handling of the partition system according to the invention, in particular when cornering in the guide device.

In an advantageous development, the guide device comprises two guide profiles arranged horizontally next to one another and the one carriage runs only on the one guide profile and the other carriage runs only on the other guide profile. The restriction "only on one guide profile" is only intended to express in the present document that the carriages do not run along both guide profiles at the same time. However, this should not, for example, rule out any additional guide means.

Due to the fact that the carriages run along only one of the two guide profiles, the further developed partition system of the invention differs from conventional partition systems with two guide profiles, in particular from the partition system of DE 196 20 045 C1 cited above, in which the carriage 12 according to FIG. 1 rests on both guide profiles 14 of the guide device 16 (and thus not “only on one guide profile”). With partition walls of this type, the two guide profiles of the guide device merge into four guide profiles at a branching point, which are required for the branched guide device. At this transition point, complicated switches or guide elements must be provided, through which the carriages are guided in the predetermined direction at the branching point. In the partition system according to the invention, only the two guide profiles have to be brought apart at a branching point without a switch, an interruption in one of the guide profiles or the like being required. Not only is this much easier and less expensive than in the prior art, it is also considerably less prone to failure.

The carriages in the further developed partition system are preferably arranged on the wall element in such a way that the vertical projection of the center of gravity of the wall element lies on the vertical projection of a line between the support points of the two rollers of the one carriage on the associated guide profile on the one hand and between the support points of the two rollers the other carriage runs on the other guide profile on the other hand. This ensures that no torque is exerted on the carriage by a vertically hanging or standing partition.

The guide device preferably has a section on which the guide profiles are arranged parallel to one another at a distance d. The two carriages are preferably arranged on the wall element in such a way that a vertical central plane of the wall element, arranged parallel to the direction of displacement, runs centrally in this section between the two guide profiles. In an advantageous development, the guide device further comprises a parking area in which the guide profiles are spaced apart from one another by a greater distance than d. Further advantages and features of the invention result from the following description, which in connection with the accompanying drawings explains the invention using exemplary embodiments.

Fig. 21 is a plan view of the carriage of Fig. 19 and 20 when driving through a curve. 4 shows a schematic sectional view of a carriage 36 according to the invention. The carriage 36 has a first section 38, on which two rollers 40 are rotatably mounted via axes 42 (shown schematically). In the cross-sectional view shown, the rollers 40 are arranged next to one another and are arranged in a V-shape relative to one another in such a way that they bear together on a guide profile 44 in the region of the top of the imaginary “V”. In the exemplary embodiment of FIG. 4, the guide profile 44 is semicircular in cross-section and the running surfaces of the two rollers 40 are circularly concave in such a way that they rest against the guide profile 44 along a support line 46 (shown thick for illustration).

The carriage 36 further includes a second portion which is formed from a bolt 48. The bolt 48 is connected to the first section 38 via a connecting bearing 50 so that it can rotate about a vertical axis 52. The axis of rotation 52 of the connection bearing 50 runs between the support points of the two rollers 40 on the guide profile 44. In the exemplary embodiment in FIG. 4, the “support points” are formed by the support lines 46. However, the “support points” can also be formed by support points, for example if the running surfaces of the rollers 40 were not adapted to the cross section of the guide profile 44. The bolt 48 is intended for connection to a load symbolized by a force arrow 53, so that it can be suspended on the bolt 48, pivoted about the vertical axis 52 and displaceably on the guide profile 44.

The carriage 36 is particularly suitable for the sliding mounting of doors (both room doors and, for example, cabinet doors) and wings, in the present description the term "wing" is understood to mean any vertically arranged, straight or curved slidably mounted plate, in particular wall elements of partition systems . sliding parts of shower cubicles u. Like. In addition, the carriage 36 can also be used for hanging curtains.

The two rollers 40 of the carriage 36 have a carrying function on the one hand by holding the carriage 36 hanging on the guide profile 44, and a guide function by causing the first section 38, which is pivotable about the load about the vertical axis 52 , glides smoothly and evenly along the guide profile 44. In particular, the inclined position of the rollers 40 prevents the tendency which is customary in the case of pivotably mounted rollers to move transversely to the direction of travel.

It should be noted that the two contact lines 46 together form a relatively large contact area of the rollers 40 on the guide profile 44. In order to achieve a comparatively large contact area with a vertically arranged roller, for example the concave roller 22 from the prior art of FIG. 1, this would have to have a very strongly concave tread. However, such a strongly concave tread leads to problems if the guide profile is guided around a curve, since the curved section of the guide profile does not fit into the concave tread. In practice, this leads to a restless, unsteady running behavior in the curve, because the edge sections of the concave tread hang on the guide profile.

the inclined arrangement of the rollers 40 in the carriage 36, however, very tight curves in the guide profile 44 can be extended exactly. Since the inclined rollers 40 not only support the carriage 36 but also guide them, no additional guide rollers, such as the guide rollers 30 in the prior art of FIG. 1, are required. As a result, the carriage 36 is structurally simpler and therefore less expensive than known carriages. In addition, it is in principle difficult to guide a conventional carriage with additional guide rollers safely and precisely around curves, as was discussed in connection with FIGS. 2 and 3. This problem does not occur in the carriage 36 according to the invention from FIG. 4, since the rollers 40, due to their V-shaped arrangement, guide the carriage 36 precisely on straight lines and in curves.

5 shows a schematic illustration of a further embodiment 54 of a carriage according to the invention. In contrast to the carriage 36 from FIG. 4, which is designed for the displaceable mounting of a hanging load on a guide profile 44, the carriage 54 is designed for the displaceable mounting of a standing load on a guide profile 56. The carriage 54 has a first section 58, on which two rollers 60 are rotatably mounted via schematically illustrated axes 62. The rollers 60 are in the sectional view shown, i.e. viewed in the direction of travel, arranged side by side and in such a V-shape relative to one another that they bear together on the guide profile 56 in the region of the top of the imaginary “V”. The carriage 54 comprises a second section 64, which is connected to the first section 58 via a connecting bearing 66 so as to be rotatable about a vertical axis 68. The second section 64 has an upper side 70 on which a load can be stored standing. The load is symbolically represented in the illustration in FIG. 5 by a force arrow 72.

6, 7 and 8 different positions of rollers 74 are shown schematically in cross-sectional views. The reference numeral 76 designates the axis of rotation of the associated roller 74, which are all in the plane of the drawing. The running direction of the rollers or an associated carriage runs perpendicular to the drawing plane in the representations of FIGS. 6 to 8. Furthermore, center lines 78 of the rollers 78, which are arranged perpendicular to the axes 76, are drawn in, which also correspond to the running direction of the rollers 74 stand vertically and therefore also lie in the plane of the drawing. The above-mentioned V-position of the rollers means more precisely the V-position of the center lines 78. 6 to 8 each show the bisector 80 of the "V" formed by the center lines 78. This bisector of the angle coincides in the representations of FIGS. 4 and 5 with the vertical axis 52 and 68, respectively.

6 to 8 show different arrangements of rollers 74 which differ primarily in the size of the angle α between the bisector 80 and the center lines 78. 6 shows an arrangement with a relatively small angle α. This arrangement is suitable if only relatively wide curves have to be driven. 7 shows a preferred arrangement in which the angle α is 45 °. In the form of the rollers 74 and α = 45 ° shown in FIG. 7, curves can be made whose radius is only about 10% larger than the radius of the roller 74. FIG. 8 shows an embodiment with an extremely large angle α.

9 to 11 show cross-sectional views of different guide profiles and rollers, the running surfaces of which are adapted to the shape of the guide profile.

9 shows a guide profile 82 which is circular in cross section and on which rollers 84 rest. The treads 86 of the rollers 84 are adapted in cross section of the guide profile 82 such that they form a support line 88 (drawn thick) with the guide profile 82, which together encompass the guide profile 82. This prevents the rollers 84 from jumping off the guide profile 82. 10 shows a cross-sectional view of a diamond-shaped guide profile 90, on which cylindrical rollers 92 rest. The cylindrical rollers 92 each have a section 94 with an enlarged diameter, with which they engage under the guide profile 90. In this arrangement, this also prevents the rollers 92 from jumping off the guide profile 90.

FIG. 11 shows a cross-sectional view of a guide profile 96 with a hexagonal cross-section, on which rollers 98 rest. The running surfaces of the rollers 98 are adapted to the cross section of the guide profile in such a way that they form a support line 100 (drawn thick) with the latter. The support line 100 has a vertical section, which effects a particularly good guidance of the rollers 98 on the guide profile 96, and an inclined portion, which simultaneously performs a leading and a supporting function of the rollers 98 on the guide profile 96.

The guide profiles 82, 90 and 96 of Figures 9 to 11 are formed by commercially available rods with standard cross sections, which do not have to be specially manufactured.

In the following, with reference to FIGS. 12 to 18, in accordance with a further aspect of the present invention, a partition system is described with wall elements which are slidably mounted in a guide device.

12 shows a plan view of a wall element 102 with a first end 104 and a second end 106, on which a first carriage 108 and a second carriage 110 are pivotably mounted. Fig. 13 is a sectional view taken along the line AA of Fig. 12 and shows the first carriage 108 in cross section. 14 is a sectional view taken along line BB of FIG 12 and shows the second carriage 110 in cross section. The first and the second carriage 108 and 110 are constructed identically and differ, as will be explained in more detail below, only in how they are attached to the wall element 102. The cross-sectional representations of FIGS. 13 and 14 show a guide device 112 with a first guide profile 114 and a second guide profile 116, which has been omitted in FIG. 12 for the sake of clarity.

As shown in FIG. 13, the first carriage 108 comprises a first section 118, on which two rollers 120 are rotatably mounted about axes 122. Similar to the exemplary embodiments in FIGS. 4 and 5, the rollers 120, viewed in the direction of travel of the carriage 108, are arranged in a V-shaped manner relative to one another in such a way that they bear together on the guide profile 114 in the region of the tip of the “V”. An upper holding plate 124 is fastened to the first section 118 with two bolts 126 (see also FIG. 12). A lower holding plate 128 is arranged vertically below the upper holding plate 126 and is connected to the upper holding plate 124 by two vertical connecting bolts 130 (see also FIG. 12). In the lower holding plate 128, a vertical support bolt 132 is rotatably mounted about a vertical axis 134. The wall element 102 is suspended from the support bolt 132. The axis of rotation 134 runs, similarly to the carriages of FIGS. 4 and 5, between the contact points of the rollers 120 on the guide profile 114. Thus, due to the weight of the wall element 102, no torque is exerted on the first carriage 108 placed on the guide profile 114.

The structure of the second carriage 110 is identical to that of the first carriage 108 and differs from it only in its arrangement on the wall element 102. This arrangement is described in more detail below. In FIG. 12, a vertical center plane 136, which is arranged parallel to the direction of displacement of the wall element 112, is shown in dashed lines. A line 138 is also drawn in, which runs between the contact points of the two rollers 120 of the first carriage on the first guide profile 114 on the one hand and between the contact points of the two rollers 120 of the second carriage 110 on the second guide profile 116 on the other hand. In the special configuration of the first and second carriages 108 and 110 (see FIGS. 13 and 14), the vertical projection of this line 138 is identical to the vertical projection of a connecting line between the vertical axes of rotation 134 of the carrying bolts 132 of the first and second carriages 108, 110.

The first and the second carriage 108, 110 are arranged on the wall element 102 such that the vertical projection of the center of gravity 139 of the wall element 102 lies on the vertical projection of the line 138. It is thereby achieved that the wall element 102 is held in a vertical position by its own weight, although it is supported on only one guide profile 114 and 116, respectively. Furthermore, the first carriage 108 and the second carriage 110 are arranged on the wall element 102 in such a way that the central plane 136 runs centrally between the first guide profile 114 and the second guide profile 116. Finally, the connecting bolts 130 are arranged between the upper holding plate 126 and the lower holding plate 128 such that they are arranged centrally between the guide profiles 114 and 116 when the first carriage 108 and the second carriage 110 are on the first guide profile 114 and the second guide profile 116 is attached.

15 shows a plan view of the first carriage 108 when cornering in the guide device 112. Due to their inclined or V-position, the rollers 120 of the first carriage 108 cause the first carriage 108 to align tangentially to the first guide profile 114. The first carriage 108 is not hindered by the wall element (not shown in FIG. 15), since it can be pivoted relative to the wall element about the vertical axis 134 (see FIGS. 12 and 13). Since the point of suspension of the wall element 102 on the first carriage 108 is on the vertical axis 134, the pivoting of the first carriage 108 (and likewise the pivoting of the second carriage 110) relative to the wall element 102 does not cause a horizontal displacement thereof. In spite of the pivotable connection to the carriages 108 and 110, the wall element moves safely on a predetermined path.

In FIG. 16, the second carriage 110 is shown when the guide device 112 traverses the same curve as in FIG. 15, but which it travels on the second guide profile 116. From FIGS. 15 and 16 it can be seen that the carriages 108 and 110 of the partition system can travel through relatively tight curves under safe guidance through the V-shaped rollers 120. In fact, in the embodiment shown, the minimum manageable radius of the curve is not limited by the rollers 120, which would enable even narrower cornering. The minimally manageable curve radius is rather limited here by the two connecting bolts 130, which would abut the inside of the second guide profile 116 if the curve radius were even narrower. As shown in FIGS. 13 and 14, the connecting bolts 130 also have a central section with a reduced diameter in order to also abut the inside of the guide profile lying outside in a curve (in FIGS. 15 and 16 of the second guide profile 116) to prevent relatively tight turns.

17 shows a plan view of the guide device 112 of the partition system according to an embodiment of the invention. The guide device 112 has a travel section 140, in which the first guide profile 114 and the second guide profile 116 arrive at a distance d parallel to one another. are ordered. In this travel section 140 of the guide device, a room partition can be constructed from a plurality of wall elements 102 arranged one behind the other. Section 140 is followed by a branching area 142, in which the first and second guide profiles 114, 116 are brought apart. In a parking area 144, the first and second guide profiles 114, 116 are again guided parallel to one another at a distance e that corresponds to the distance between the attachment points of the carriages 108, 110 on the wall element 102.

If the wall element 102 located in the travel section 140 of the guide device 112 in the representation of FIG. 17 is displaced in the direction of the branching area 142, then the leading first carriage 108 on the first guide profile 114 is guided straight through the branching area 142, while the trailing second Carriage 110 is deflected to the right on the second guide profile 116 in the branching area 142. In this way, a plurality of wall elements 102, which are arranged one behind the other in section 140 of guide device 112 in order to form a continuous partition wall, are arranged next to one another in space-saving manner in parking area 144. As a result, the wall elements 102 can be stored in a space-saving manner in the parking area 144 when the partition is not required.

Since the two carriages 108 and 110 of each wall element are each supported on only one guide profile 114 and 116, the branching at 142 can be realized very easily. Although the first end 104 and the second end 106 of each wall element 102 are guided on different tracks after passing through the branching area 142, no switches or crossings are required, which are typically complex and nevertheless have problems in handling and / or in the longevity of the Bring partition system with it. An alternative embodiment of a parking area 144 is shown in FIG. The arrangement of the guide profiles 114, 116 of the guide device 112 causes the wall elements 102 to be rotated when passing through the branching area 142 and to be mounted perpendicular to the direction of construction of the partition. Depending on the available storage space, the arrangement of Fig. 17 or the arrangement of Fig. 18 can be selected. The distance between the two guide profiles 114, 116 in the parking area 144 can also be selected to be shorter than the distance e, which leads to an oblique arrangement of the wall elements 102 in the parking area 144 and may be suitable in order to optimally use the available space.

FIG. 19 shows a further embodiment 150 of a carriage according to the invention in a sectional view which corresponds to that of FIG. 13.

The carriage 150 and its arrangement on the wall element 102 corresponds in many parts to the carriage 108 from FIG. 13. Similar parts in the two carriages 108 and 150 are designated by the same reference numerals and are not described again here.

The carriage 150 differs from the carriage 108 of FIG. 13 in that on its upper holding plate 126 'two pairs of V-shaped rollers 152 and 154 are arranged one behind the other in the direction of travel (in FIG. 19 the rollers 154 are of the Castors 152 covered, see Fig. 20). The pairs of rollers 152 and 154 are each pivotally mounted on the upper holding plate 126 by means of a bolt 156 about a vertical axis. 20 shows a plan view of the carriage 150 from FIG. 19, in which some parts have been omitted for the sake of clarity and the other parts are shown in a transparent manner. As can be seen in FIG. 20, the vertical axis of rotation 134 of the carrying bolt 132 is located centrally between the bolts 156, that is to say centrally between the vertical pivot axes of the pairs of rollers 152 and 154.

The carriage 150 is suitable for slidably supporting even heavier loads, in particular for large wall elements of partition systems, since the load is distributed over two pairs of rollers. In addition, the arrangement of the pairs of rollers 152, 154 in succession together with the double pivotability, namely around the vertical axis 134 on the one hand and around the respective bolts 156 on the other hand, leads to a smooth, precise drive around curves.

21 shows the carriage 150 in a sequence of snapshots when driving through a curve in the guide profile 114. Note how the two pairs of rollers 152, 154 adapt to the curvature of the guide profile by individual pivoting about their vertical pivot axes. It should also be noted that even if one of the pairs of rollers should come out of the ideal track somewhat by pivoting about the vertical axis, the upper holding plate 126 'does not leave the ideal path, which leads to a smooth, smooth running of the carriage 150.

Instead of two pairs of rollers, three or more pairs of rollers can be arranged one behind the other on a carriage, each pivotable about vertical axes, in the direction of travel.
