Description

Technical Field

[0001] The present invention relates to a sliding bearing assembly comprising a slider and a track according to the preamble of claim 1, and to the application of a component of the track for implementing such a sliding bearing assembly. Background Technology

[0002] Such sliding bearing assemblies include a slider and a track as elements configured corresponding to each other. While the track is typically fixed in position to a building structure, such as a room wall or floor, or to a device arranged on the room wall and / or floor, the slider can be guided to move along the track. In a given operating state of such a sliding bearing assembly, the slider is arranged on the track in such a configuration that, through the mutual engagement of the track and the slider, the slider is fixed in its position relative to the track perpendicular to the longitudinal direction, while it is capable of sliding along the track in the longitudinal direction, and its position perpendicular to the longitudinal direction remains unchanged. The track typically has an extension length in the longitudinal direction that is at least 4 times, particularly at least 5 times, particularly at least 10 times, particularly at least 15 times, and particularly at least 20 times, the extension length of the slider in the longitudinal direction. For many applications, the longitudinal displacement of the slider, in multiples of its extended length as exemplified above, is important so that the slider can reliably be guided along the track over the corresponding displacement length, for example, for transporting devices or components of devices mounted on the slider, such as tool components or support and / or gripping devices for transport systems. To achieve the desired characteristics, the track typically has a guide section and the slider has a guide receiver, wherein, in the operating state of the sliding bearing assembly, the track is arranged in the guide receiver such that a limiting wall constructed by the guide receiver fixes the position of the guide section within the guide receiver perpendicular to the longitudinal direction; however, the slider's displacement relative to the track, and therefore the movement of the guide section and the guide receiver in the longitudinal direction, is possible. The guide receiver is typically constructed as a through-hole that passes uninterruptedly through the slider in the longitudinal direction.

[0003] One challenge in implementing such sliding bearing assemblies lies in configuring the elongated track or the elongated guide section of the track such that the slider can be guided to move relative to the track with the lowest possible friction. In the prior art, it is known to manufacture the track from components pinned together and thus tightly abutted and fixed in position, or as a one-piece component of the required length depending on the application, for example as an extrusion or die casting. Generally, preferably, at least the guide section of the track, and especially the entire track, is made of metal, particularly a metal alloy. However, the manufacture of such long, one-piece tracks is laborious and costly due to storage, transportation, and handling of the track during its manufacture. In particular, such tracks are typically manufactured by fastening fastening elements to a prefabricated shaft forming the guide section of the track, by means of which the track can subsequently be secured to a base. This fastening is particularly problematic when implementing tracks for sliding bearing assemblies used in food manufacturing. This type of sliding bearing assembly, particularly relevant to the present invention and suitable for use in food manufacturing processes, is typically manufactured in accordance with hygiene guidelines according to DIN EN1672-2, thus making it particularly easy to clean. In particular, such sliding bearing assemblies are not allowed to have gaps that allow dirt to accumulate and become difficult or impossible to remove during routine cleaning. In the track implementation described above, fastening elements are typically welded to the shaft to prevent gaps. Welding of components, and especially subsequent post-weld treatment, ensures that the sliding bearing assembly meets standard surface requirements so that it can be easily cleaned in operation, for example, using cleaning fluids such as water or water-based cleaning fluids comprising water and chemicals dissolved in it, for example, with a flushing pressure of 25 bar. However, welding at long tracks is laborious, as it requires welding equipment capable of receiving long shafts or tracks, and welding numerous fastening elements results in a significant heat input and thus a risk of thermal deformation. Summary of the Invention

[0004] As a solution to the task upon which this invention is based, the present invention proposes a sliding bearing assembly having the features of claim 1. This sliding bearing assembly includes a slider and a track extending longitudinally, wherein the track includes a guide section having a total extension length in the longitudinal direction. The slider has a guide receiving portion for receiving the guide section. In the operating state of the sliding bearing assembly, the guide section is arranged in the guide receiving portion. From the operating state, the slider can continuously slide relative to the track in the longitudinal direction along the guide section over its total extension length, while its position perpendicular to the longitudinal direction is continuously fixed due to the guide section arranged in the guide receiving portion. The sliding bearing assembly according to the invention may have other features disclosed herein in conjunction with such sliding bearing assemblies. Preferably, the sliding bearing assembly according to the invention meets the requirements according to DIN EN 1672-2. According to the invention, the track has a plurality of track sections arranged sequentially in the longitudinal direction and collectively forming the guide section of the track, wherein corresponding two adjacent track sections in the longitudinal direction are spaced apart by a longitudinal distance. Deviating from the known prior art methods of implementing tracks using track components (i.e., arranging the guide sections of the track as directly, especially with material locking, as possible), this invention is based on the understanding that by arranging the longitudinally adjacent track sections of the track at intervals, the track can be implemented particularly simply and cost-effectively, and despite such spacing, it can still be ensured that the slider can be guided and moved reliably along the track with low friction over the entire extension of the guide section. The intentionally set longitudinal spacing ensures that there is free space between the track sections, which can be easily flushed. Furthermore, the intentionally set longitudinal spacing in some embodiments allows for a particularly simple arrangement of the track sections flush with each other. In one embodiment, the track sections are constructed as longitudinally spaced sections of a track component manufactured as a single piece. In an alternative embodiment, the track has multiple track components, which are manufactured independently of each other and thus configured as individual track components. Each track component comprises one of the track segments, and in particular, another track segment of the track, which is explained in more detail below. These track components are aligned and fastened to the carrier to realize the track. It has proven particularly advantageous to set the longitudinal spacing between two adjacent track segments, i.e., the distance between their longitudinal ends facing each other relative to the longitudinal direction, to be greater than 3 mm, especially at least 5 mm, especially at least 6 mm, especially at least 7 mm. This, in particular, ensures the particularly advantageous washability of the track. Furthermore, it has proven particularly advantageous to set the longitudinal spacing to be less than 15 mm, especially less than 10 mm.This ensures the slider's low-friction displacement with minimal disruption along the total length of the guide section of the track. It should be considered that the guide section is constructed from multiple track segments, each of which constitutes a portion of the total longitudinal length of the guide section, such that when the slider begins to move relative to the track along the total length of the guide section from the operating state, the slider moves along all track segments. The operating state here refers to the specific arrangement between the track and the slider. In the operating state, the slider is in a specific longitudinal position relative to the track, wherein the guide section of the track is arranged in the slider's guide receiving portion.

[0005] In one embodiment, each track segment has a guide region extending over at least 80% of the longitudinal extension of the track segment, and each track segment has a cross-section in the guide region corresponding to a guide receiving portion. When the slider moves within the guide region by means of its guide receiving portion, the guide receiving portion preferably remains uniformly abutted against the corresponding cross-section of the track segment throughout the entire longitudinal extension of the guide region. The guide region is spaced apart from at least one longitudinal end of the corresponding track segment, wherein the track segment preferably has a chamfer between the longitudinal end and the guide region, such that the cross-section at the longitudinal end is smaller than the cross-section within the guide region. Particularly preferably, the chamfer, i.e., the outer side of the track segment within the chamfered region, has an angle between 30° and 80°, particularly between 45° and 70°, relative to the longitudinal direction. Preferably, the track segment has the same cross-section throughout its guide region. Preferably, the track segment has an average cross-section over its guide region, wherein the cross-section at the longitudinal end is smaller than the average cross-section of the guide region. Generally, preferably, each track segment has a guide region, as explained above, extending over at least 80% of its longitudinal extension, and the track segment has a cross-section in the guide region corresponding to the guide receiving portion, as explained above. The guide region is spaced apart from at least one longitudinal end of the corresponding track segment, and the cross-section at the longitudinal end is smaller than the cross-section within the guide region, particularly smaller than the average cross-section of the track segment over the guide region. Preferably, the cross-section at the longitudinal end is less than 90%, particularly less than 80%, and particularly less than 70% of the cross-section within the guide region. Preferably, the guide region is spaced apart from two longitudinal ends of the corresponding track segment, and at each of the two longitudinal ends, the cross-section is smaller than the cross-section within the guide segment. Preferably, a chamfer is provided between the respective longitudinal ends and the guide region, as explained above. Preferably, the above characteristics apply to all track segments. Preferably, the chamfer extends over a longitudinal extension of less than 10 mm, particularly at most 5 mm, particularly greater than 2 mm, and particularly greater than 3 mm. The inventors have recognized that by setting a longitudinal spacing between adjacent track segments in the longitudinal direction and by varying the cross-section of the respective track segments, it is possible to ensure, in a particularly simple manner, that the slider slides along the track with low friction, even at discontinuities between the track segments. Generally preferably, one or more track segments are constructed as hollow cylinders, wherein a tapered deviation relative to the shape of the hollow cylinder is formed at the chamfer. Typically, the chamfer is constructed to be completely surrounding the longitudinal direction.

[0006] In one embodiment, at least a portion of the guide receiver is constructed of a sliding section of a slider, on which the slider abuts against a specific track segment in the operating state. In the operating state, the slider, along with its longitudinal extension, preferably extends only within the longitudinally extending region of one of the track segments. In a preferred embodiment, the slider and its sliding section abut against only one specific track segment in the operating state. This abutment can be direct abutment or abutment with a small gap. In any case, by abutting against the sliding section, the position of the specific track segment relative to the slider is fixed in any direction perpendicular to the longitudinal direction. Preferably, in the operating state, the slider abuts against only one specific track segment with its sliding section. The sliding section has a longitudinally extending length in the longitudinal direction that is at least 1.5 times, particularly at least 2 times, and particularly at least 3 times, the specific track segment being spaced apart from the other track segments of the track adjacent to the specific track segment in the longitudinal direction by the longitudinal distance. Preferably, the sliding section has a longitudinal extension length that is a corresponding multiple of each of the longitudinal spacings, by which a specific track section is spaced apart from a track section at each of its longitudinal ends, the track sections being arranged adjacent to the specific track section at their respective longitudinal ends. By providing sliding sections with a correspondingly large longitudinal extension, particularly low-friction displacement of the slider along the track can be ensured, even at discontinuities between two adjacent track sections. In one embodiment, the sliding section has a plurality of lower sliding sections spaced apart from each other in the longitudinal direction; in another embodiment, the sliding section is constructed uninterrupted along its entire longitudinal extension. Generally preferably, the sliding section of the slider is made of a sliding material, especially a friction polymer. Generally preferably, a sliding plastic is used as the sliding material. This is understood herein as a polymeric material having a low coefficient of friction relative to the stainless steel that serves as the sliding mating element. Preferably, without lubrication, the sliding plastic has a coefficient of friction of <0.3, especially <0.25, especially <0.2, relative to stainless steel. Suitable sliding plastics include thermoplastic polymers such as polyethylene, polypropylene, polyacetal, polycarbonate, polyamide, polyvinyl chloride, polytetrafluoroethylene, and thermosetting phenolic resins. To further reduce friction, these plastics can be filled with lubricants, particularly finely powdered solid lubricants such as molybdenum disulfide or graphite. Such lubricant-containing polymers are also known as friction polymers. In one embodiment, the slider, as a separate component, has a slider body on one hand and at least one sliding element on the other, wherein the sliding element is made of a sliding material, and preferably, the sliding section is constructed from the at least one sliding element. Preferably, the sliding element is formed by injection molding.Preferably, the sliding element is constructed as a hollow cylinder, wherein, particularly preferably, the hollow cylinder has a longitudinally penetrating slit in its cylinder wall, through which a web section of the track extends in the running state, the web section connecting the guide section of the track to the track body. In one embodiment, the slider is generally made of a sliding material, particularly as a one-piece component, especially by means of injection molding, or by processing (e.g., milling) a semi-finished product pre-extruded from the sliding material.

[0007] Generally, the sliding section has a stop section that, in operation, rests against a guide section of the track, wherein every two adjacent stop sections are spaced apart from each other relative to the direction of rotation about a longitudinal axis extending in the longitudinal direction. This ensures, on the one hand, reliable guidance of the slider perpendicular to the longitudinal direction relative to the track by the stop sections, and on the other hand, the washability of the sliding bearing assembly by the spacing between the stop sections. Preferably, the stop sections are spaced apart in such a way that the guide sections have flushing recesses between the stop sections relative to the direction of rotation, and / or, the sliding sections have flushing recesses between the stop sections relative to the direction of rotation, such that in the operating state, flushing channels are constructed between the two stop sections, extending between the guide and sliding sections of the track and thus also between the guide receiving sections. Preferably, the flushing channels extend continuously in the longitudinal direction and are open at both longitudinal ends, allowing cleaning fluid to enter the flushing channel at one longitudinal end and exit at the other longitudinal end. Therefore, the flushing channels are externally accessible at both longitudinal ends in the operating state of the sliding bearing assembly. Preferably, two adjacent flushing recesses or flushing recesses and the stop sections arranged between them are parallel to each other and extend parallel to the longitudinal direction. Particularly preferably, the flushing recesses or flushing channels extend within an angular range in a rotational direction about the longitudinal axis, this angular range being at least 0.7 times, particularly at least 0.9 times, particularly at least 1.0 times, particularly at least 1.2 times, particularly at least 1.5 times, and particularly at least 2.0 times, the angular range in which the stop section extends in the rotational direction. It should be considered that the extension of the stop section along the rotational direction, i.e., the angular range in which the stop section extends, is defined such that, in the operating state, the stop section provides a stop for the guide section during movement away from the axis of the guide receiving portion. The sufficient width of the flushing recesses or flushing channels relative to the rotational direction provides sufficient flushability or sufficient cleaning possibility for the component in the operating state. Therefore, the sufficient width of the flushing recesses or flushing channels ensures that, at any possible location of the guide section in the guide receiving portion, there is always sufficient intermediate space between the boundary wall and the guide section due to the flushing recesses, thereby ensuring cleaning possibility. Particularly preferably, the flushing channels have a net diameter of at least 2 mm, especially at least 3 mm, especially at least 4 mm, especially at least 5 mm, in a direction extending perpendicular to the longitudinal axis.Particularly preferably, the flushing channels have a net cross-section of at least 4 square millimeters, particularly at least 6 square millimeters, particularly at least 10 square millimeters, and particularly at least 15 square millimeters in their longitudinal extension in a direction perpendicular to the longitudinal axis. Therefore, when cleaning the sliding bearing assembly, the cleaning fluid can flow through the net cross-section.

[0008] In one embodiment, each track segment has a fastening recess extending perpendicular to the longitudinal direction. In an embodiment that can be particularly advantageously combined with the above embodiments, each track segment is connected to a fastening block having a recess for introducing a fastening device to fasten the block to a substrate. Generally, the substrate can be provided by the carrier illustrated herein. The fastening recess can be configured, for example, as a fastening hole, and the recess can be configured, for example, as a hole. The fastening recess is preferably configured to allow the introduction of a fastening device for fastening the respective track segment to the substrate by means of the fastening device. Alternatively, the fastening recess can be configured such that a fastening device for fastening the track segment to the fastening block by means of the fastening device can be introduced into the fastening recess. Generally preferably, the fastening recess is configured as a blind hole type, such that it is not a through hole through the track segment. This may be particularly advantageous for cleaning purposes and / or for low-friction sliding guidance. Particularly preferably, in the operating state of the sliding bearing assembly, the upper side of the corresponding track section is closed at the height of the fastening recess, while the lower side is provided with an opening by the fastening recess. This prevents dirt from accumulating in the fastening recess as much as possible. Generally preferably, the sliding bearing assembly includes at least one fastening device, wherein the corresponding track section and / or the corresponding fastening block is fastened to the substrate by means of the fastening device, particularly to a substrate constructed of a carrier. For example, the fastening recess or recess may have internal threads, thereby enabling the track section or fastening block to be fixed to the substrate or carrier in a simple manner by means of screws. Generally preferably, the track section and the respective fastening block and / or the respective fastening device are all made of metal, wherein preferably, each track section is equipped with at least one fastening block and / or at least one fastening device.

[0009] In one embodiment, the track sections are respectively connected to fastening element materials in a locking manner, particularly by means of adhesive bonding or welding. The fastening element can be constructed as a fastening block as illustrated herein. The locking connection between the fastening element and the track sections is particularly advantageous in preventing the accumulation of contaminants at the transitions between the fastening elements. Particularly preferably, the sliding bearing assembly comprises a plurality of track components, each comprising at least one track section and a fastening element, wherein the sliding bearing assembly is achieved by arranging the different track components and their track sections spaced apart from each other in the longitudinal direction (particularly fixed to the carrier). Generally preferably, the track sections can be independently fastened to the carrier. Preferably, each track section is manufactured independently as a separate component. Particularly preferably, in the operating state of the sliding bearing assembly, all track sections are fastened to the carrier and spaced apart from each other in the longitudinal direction as illustrated.

[0010] In one embodiment, at least two longitudinally adjacent track sections are connected to each other in operation by a hinge, the track sections being arranged at an angle to each other by the hinge. The hinge arranged between the two longitudinally adjacent track sections preferably spans at least a portion of the longitudinal distance between the two track sections. Preferably, the hinge defines a hinge axis extending perpendicular to the longitudinal direction, wherein adjacent track sections are pivotable about the hinge axis by means of the hinge, wherein they have an angle defined about the hinge axis, preferably 180°, in operation. Here, this angle relates to the track section axis of the respective track section, wherein in operation, the track section axis of the adjacent track sections extends in the longitudinal direction, such that a slider in operation can be displaced relative to the track in the longitudinal direction parallel to the track section axis over the two adjacent track sections and over the longitudinal distance between them. The track section axis is therefore the axis along which the slider is guided to move relative to the track section. Preferably, the sliding bearing assembly is configured to adopt an angled state from the operating state, wherein adjacent track sections pivot about a hinge axis by means of a hinge, preferably at least 30°, particularly at least 45°, particularly at least 60°, particularly at least 90°, wherein, preferably, during the pivoting process that switches the sliding bearing assembly from the operating state to the angled state, the slider remains arranged on one of the two adjacent track sections. Generally preferably, in one embodiment, the hinge is spaced above the two adjacent track sections in a vertical direction perpendicular to the longitudinal direction, wherein the upper side forms the vertical end of the track section. In one embodiment, the hinge is arranged vertically below the adjacent track sections. Generally preferably, the carrier has two carrier elements, wherein one of the adjacent track sections is fastened to each of the carrier elements, wherein the carrier elements are connected to each other by hinges, particularly pivotally connected to each other about the hinge axis of the hinge. Therefore, it is preferred that the track sections are pivotable to each other by means of the carrier elements and the hinges arranged between them.

[0011] Generally preferably, the track section is made of metal. Generally preferably, the guide receiving part of the slider, and especially the entire slider, is made of a sliding material. Generally preferably, the entire track is made of metal.

[0012] In one embodiment, the track has another guide section, which is constructed from a first group of track sections and a second group of track sections. The first group of track sections is arranged parallel to the second group of track sections. Therefore, the track section axis of the first group of track sections extends parallel to the track section axis of the second group of track sections in the operating state. Furthermore, the parallel arrangement of the first and second groups of track sections refers to the operating state. In the transverse direction perpendicular to the longitudinal direction, the first group of track sections is spaced apart from the second group of track sections. In the advantageous sliding bearing assembly embodiment described above, the slider has another guide receiving portion assigned to the other guide section, such that in the operating state, the guide section is arranged in the guide receiving portion and the other guide section is arranged in the other guide receiving portion. Therefore, the slider can be guided by its two guide receiving portions on the two guide sections of the track and move relative to the track in the longitudinal direction, wherein the other guide section and the other guide receiving portion can be configured correspondingly to each other and can have the features currently described with reference to the guide receiving portion and guide section. By providing guide receivers and additional guide receivers, as well as guide sections and additional guide sections, particularly reliable and load-bearing guidance of the slider relative to the track can be ensured. In one embodiment of the advantageous sliding bearing assembly, the sliding bearing assembly has another slider with another guide receiver assigned to the other guide section, wherein the other guide receiver of the other slider can be configured to correspond to the other guide section of the track, as explained herewith reference to the guide receivers and guide sections. This sliding bearing assembly offers the particular advantage that the two sliders can be supported with displacement in the longitudinal direction on the same track.

[0013] Generally, preferably, the track segments of the first group are staggered relative to the track segments of the second group in the longitudinal direction. Therefore, the longitudinal ends of the track segments of the first group are staggered relative to the longitudinal ends of the track segments of the second group in the longitudinal direction, preferably by at least twice, particularly at least five times, particularly at least ten times, the maximum longitudinal spacing between two longitudinally adjacent track segments in one of the groups, and / or, preferably by at least 10%, particularly at least 20%, particularly at least 30%, of the longitudinal extension length of the shorter of the two track segments with staggered longitudinal ends in the two groups. In the staggered arrangement of the longitudinal ends of the two track segments in the two groups, this naturally refers to the staggered arrangement of the longitudinal ends of those track segments extending parallel and side-by-side within the same longitudinal extension section in the two groups. Through the staggered arrangement of the track segments, the longitudinal spacing between two longitudinally adjacent track segments in the corresponding group is staggered relative to the longitudinal spacing between two track segments in the other group, wherein this staggering is, of course, a staggering in the longitudinal direction. By staggering the arrangement, it is possible to ensure particularly reliable guidance of the slider throughout the entire guide section and especially throughout the entire other guide section of the track, because the slider with two guide receiving parts can always be guided in such a longitudinal region on one of the two guide sections of the track, in which the other guide section of the track has a discontinuity due to the longitudinal spacing between its two track sections.

[0014] In one embodiment, the corresponding track sections of the first group and the track sections of the second group are integrated into a single track component. This simplifies the manufacturing of the sliding bearing assembly. Particularly preferably, the individual track components can be independently fastened to a carrier. Particularly preferably, the track sections integrated into the corresponding track components are non-detachably connected to each other. For example, both track sections integrated into the track component can be welded to a fastening block, by means of which the track component can be fixed to the carrier or substrate, especially as explained above.

[0015] The invention also relates to the application of separate track components for realizing a longitudinally elongated track. The track is suitable for use in a sliding bearing assembly that includes a slider in addition to the track. The track has a guide section having a total extension length in the longitudinal direction. The slider has a guide receiving portion for receiving the guide section. In the operating state of the sliding bearing assembly, the guide section is arranged in the guide receiving portion. From the operating state, the slider can slide continuously relative to the track in the longitudinal direction along the guide section over its total extension length, while its position perpendicular to the longitudinal direction is continuously fixed due to the guide section arranged in the guide receiving portion. In the application according to the invention, the track components are arranged sequentially in the longitudinal direction, spaced apart from each other, thereby forming a track, wherein each track component separately constitutes a track segment of the track and the track segments together constitute a guide segment of the track. In one embodiment, the track component has other components in addition to the track segment, such as a fastening block and / or another track segment. Preferably, the track components for realizing the track are fixed to the carrier in a longitudinally spaced manner and arranged sequentially in the longitudinal direction, and are fixed in a particularly detachable manner, particularly by means of at least one fastening device.

Applications of the invention can have the features described in conjunction with embodiments of the sliding bearing assembly according to the invention. Sliding bearing assemblies according to the invention can have the features illustrated in conjunction with embodiments of applications according to the invention.

[0017] The invention will now be explained in more detail with reference to the seven accompanying drawings and embodiments.

[0018] It shows: Figure 1 The track of the sliding bearing assembly according to the present invention in the schematic diagram; Figure 2 According to the schematic diagram Figure 1 A top view of the track section along the longitudinal direction in the implementation method; Figure 3 According to the schematic diagram Figure 1 Detailed view of the track section of the implementation method; Figure 4 : A track according to another embodiment of the sliding bearing assembly according to the invention in a schematic diagram; Figure 5: Track of another embodiment of the sliding bearing assembly according to the present invention in different schematic diagrams; Figure 6 : Track of another embodiment of the sliding bearing assembly according to the present invention in different schematic diagrams; Figure 7: Various components of another embodiment of the sliding bearing assembly according to the present invention in different schematic diagrams. Detailed Implementation

[0019] exist Figure 1 The schematic diagram illustrates a track 1000 according to one embodiment of a sliding bearing assembly based on the present invention. The track 1000 of this embodiment has exactly one guide section, which is formed by three track segments 1 of the track 1000. These three track segments 1 are each constructed as a column type extending in the longitudinal direction X, which is generally advantageous according to the present invention. To construct the guide section of the track 1000, the track segments 1 are arranged successively in the longitudinal direction X, wherein corresponding two adjacent track segments 1 are spaced apart from each other by a longitudinal distance S. Here, the longitudinal distance S refers to the distance between the two mutually facing longitudinal ends of two adjacent track segments 1. Figure 1 In the implementation of the track 1000 track segment 1, Figure 2 and Figure 3 Further schematic diagrams are shown in more detail. Combined with... Figures 1 to 3 As can be seen, each of the track segments 1 has a first longitudinal end 11 and a second longitudinal end 13, between which the track segment extends in its longitudinal length. Starting from the respective longitudinal ends 11, 13, each of the track segments 1 has chamfers 12, 14, such that the diameter of the track segment 1 perpendicular to the longitudinal direction X increases from the respective longitudinal ends 11, 13 toward the longitudinal center of the track segment 1, which is generally advantageous according to the invention. Thus, the track segment 1 has a diameter D2 at each of its two longitudinal ends 11, 13, and in the guide region indicating the longitudinal region of the track segment 1 spaced apart from the longitudinal ends 11, 13, it has a diameter D1 that is significantly larger than the diameter D2. The guide region and the respective longitudinal ends 11, 13 are connected to each other by the respective chamfers 12, 14, and the guide region has a constant diameter D1 over its entire longitudinal extension, which is generally advantageous according to the invention. Generally preferably, the guide region has the same maximum diameter D1 throughout its entire longitudinal extension, which, as explained herein, is significantly larger than the maximum diameter D2 provided at the two longitudinal ends of the track section 1.

[0020] exist Figure 3The lower side of track section 1 is shown, where the term "lower side" refers to the vertically downward side when the sliding bearing assembly is in operation. A plurality of fastening recesses 15 are provided on this lower side, into which pins and / or externally threaded screws can be inserted to secure the track section to the carrier.

[0021] exist Figure 4 The schematic diagram illustrates a track 1000 according to another embodiment of the sliding bearing assembly of the present invention. The track 1000 includes, in addition to a first guide section, another guide section extending parallel to the first guide section but spaced apart from it in a transverse direction Y perpendicular to the longitudinal direction X. The first guide section is formed by a first group of track sections 1, while the other guide section is formed by a second group of track sections 100, wherein the track 1000 includes both the first group of track sections 1 and the second group of track sections 100. The first group of track sections 1 are staggered relative to the second group of track sections 100 in the longitudinal direction X, such that a corresponding one of the track sections 1, 100 of one group extends in a section (relative to the longitudinal direction X) where a longitudinal spacing, as explained, is provided between two adjacent track sections 1, 100 of the other group in the longitudinal direction X. Furthermore, the configurations of the track sections 1, 100 correspond respectively to... Figures 1 to 3 The configuration of track segment 1 is illustrated in the embodiment shown.

[0022] In Figure 5 (including) Figure 5a and Figure 5b The diagram schematically illustrates a track 1000 according to another embodiment of a sliding bearing assembly based on the invention. Track 1000 includes two track components 103 and 104, each having a track section 1 and two fastening blocks 17. The track section 1 is configured similarly to the reference diagram. Figures 1 to 4The illustrated track segment 1, however (in the case of constructing corresponding track components 103, 104) is connected to two fastening blocks 17 respectively, by means of pins fixing the fastening blocks 17 to the fastening recesses 15 and subsequently welding the fastening blocks 17 to the corresponding track segment 1. The track components 103, 104 of the track are constructed identically. Generally preferably, the track according to the embodiment of the invention has multiple track components 103, 104, wherein at least most, especially all, of the track components 103, 104 are constructed identically. In the current sliding bearing assembly, the track components 103, 104 are respectively fastened to the carrier elements 3, 4 of the carrier. Currently, the carrier elements 3, 4 are wooden boards. Carrier elements 3 and 4 are connected to each other by means of hinge 5, wherein hinge 5 defines a hinge axis extending perpendicular to the longitudinal direction X, such that carrier elements 3 and 4, and thus track components 103 and 104 fixed thereon, are supported by means of hinge 5 so that they can pivot about the hinge axis. Although Figure 5b The track 1000 shown is in its shape as it is in the operating state of the sliding bearing assembly, but... Figure 5a The middle track components 103 and 104 are at an angle to each other. Figure 5a and Figure 5b The slider of the sliding bearing assembly is not shown, but its placement would be natural to those skilled in the art.
