Description

Technical Field

[0001] This invention generally relates to the field of energy steering chains for guiding conduits such as cables or hoses. Typically, energy steering chains are used to guide a supply line for electricity, data, or media between an interface and a movable consumer, which is relatively movable to this interface. They typically comprise multiple links that are oscillatingly connected to each other.

[0002] The present invention particularly relates to a so-called dividing slat or partition slat for a link in an energy guiding chain. Background Technology

[0003] At least a portion of a link consists of two laterally outwardly arranged side plates or side members and at least one transverse slat (sometimes also called a crossbar), which holds the side plates parallel. One or more transverse slats can be fixedly or detachably connected to the side plates (so-called open slats). Viewed in a cross-section perpendicular to the longitudinal direction of the energy guiding chain, the side plates and transverse slats define the receiving space within the link. Thus, the links collectively form a longitudinally continuous guiding channel in which conduits are received.

[0004] In applications with multiple guided pipelines, it is advantageous to subdivide the receiving space, or guiding channel, into separate areas, i.e., to create an internal partition of the energy guiding chain. This, in particular, reduces or avoids friction between pipelines caused by relative motion in different radii of curvatures, or turning arcs. In principle, pipelines with significantly different diameters should be guided separately. Internal partitioning also allows for permanent arrangements of weight distribution in cases where pipelines have different weights.

[0005] Internal partitioning is especially designed to prevent unwanted movement of tubing in the guide channels, such as twisting (so-called "plugging") or movement of tubing on top of each other, which could, for example, cause the hose to be crushed by heavy wires.

[0006] To allow for vertical subdivision, i.e., to divide the width of the receiving space, dividing strips or partition strips are provided. They run substantially parallel to the side panels and are generally positioned on the transverse strips. For example, the applicant's utility model DE 29907 443 U1 or patent application DE 43 13 242 A1 describes dividing strips for segments of the energy guiding chain.

[0007] To make horizontal divisions, that is, to subdivide the usable height of the receiving space, so-called grid bases (also known as frame bases, insert bases, etc.) are set up, similar to crossbeams. These grid bases serve as supports for pipelines. They run parallel to the transverse slats (i.e., substantially perpendicular to the side panels) and are typically held on dividing slats or partition slats. Grid bases are described in patent EP 0 343192 B1.

[0008] Currently, dividing slats are understood as special partition slats having at least one side, preferably both sides, a plurality of supports or devices for mounting the grid base. Therefore, dividing slats inherently offer various possibilities for selectively mounting the grid base within an interior space.

[0009] The applicant's patent EP 0 343 192 B1 also discloses a proven construction method for a dividing slat that allows for height division by means of finely segmented grid bases. EP 0 343 192 B1 discloses a dividing slat having a plate-like base with upper and lower end regions for releasable fastening to a transverse slat, two large main sides, and two opposing narrow sides extending in the height direction between the end regions. A plurality of retaining grooves are provided on each of the two main sides, extending substantially perpendicular to the height direction. Optionally, a plate-like grid base can be moved into and held in each retaining groove at corresponding ends, wherein the grid base forms a key on the end side that functions in conjunction with the retaining groove in the form of a keyway connection.

[0010] These dividing strips allow for fine segmentation in the height direction. Compared to a coherent receiving opening or break for the grid base, a smaller grid size is achieved through the smaller spacing between retaining slots, allowing for selective positioning of the grid base.

[0011] For assembly, the principle is to achieve easy handling and assemblability of components used for internal partitioning with minimal time and effort. For maintenance purposes, such as replacing pipelines, the separate areas of the internal partitioning of the receiving space should be easily accessible, which typically requires removing the grid floor. It is also desirable to be able to easily change the partitioning as needed, such as when further subdivision is required later. In existing solutions for internal partitioning, there is room for improvement in terms of ease of handling, or user-friendliness. Summary of the Invention

[0012] Based on the described prior art, the first objective of this invention is to provide a solution for internal partitioning, and in particular a partition strip further developed for this purpose, which simplifies handling during assembly and maintenance or is configured to be more user-friendly.

[0013] This is achieved using the dividing strips according to the invention, or using the links according to the invention, or using the energy guiding chain according to the invention.

[0014] According to the invention, in the dividing slats or partition slats, at least some, and preferably all, retaining grooves are respectively implemented as being continuous from one narrow side to the other and having an introduction opening on each narrow side. Thus, a grid bottom can be introduced through the respective introduction opening from both sides of the chain, or from both sides, or in both (travel) directions, and therefore can be selectively introduced into and removed from the respective retaining groove in one of two opposite assembly directions. Furthermore, according to the invention, the dividing slats are provided with a locking device or locking mechanism that locks one or more assembled grid bottoms to prevent unwanted movement in the two assembly directions and thus prevent unwanted loosening from the respective retaining grooves.

[0015] Maintaining accessibility of the slot in two opposite directions provides a decisive advantage in practice when inserting and removing the grid base and improves user-friendliness, as the user no longer needs to pay attention to the specific assembly and disassembly directions of the grid base. Alternating operation in both directions is also feasible, which can be advantageous in the case of multiple grid bases stacked vertically. Different feasibility exists regarding locking mechanisms, especially those that allow for operation with minimal force.

[0016] The insertion and removal of the grid bottom in the corresponding holding slot can be achieved, in particular, by translating it in and out along the longitudinal direction of the energy guide chain, or perpendicular to the height direction.

[0017] To this end, the proposed dividing strip has, at least in the main portion of the retaining groove, and preferably in each retaining groove, a first inlet opening on one narrow side and a second inlet opening on the opposite narrow side, meaning the retaining groove is open or accessible on both sides. This can be particularly configured for all retaining grooves on both main sides. With these two inlet openings, each retaining groove is essentially inserted in the longitudinal direction of the energy guide chain and is thus open on both sides. The retaining grooves respectively retain the ends of the corresponding configurations of the grid bottom in a direction perpendicular to the substrate. The retaining grooves preferably run perpendicular to the height direction and parallel to the main plane between the two main sides of the substrate. The retaining grooves can particularly be implemented as a cut-out in the main side, the cross-section of which, perpendicular to the main plane, allows for shape-locking retention, especially in the form of a keyway connection, for example, using a dovetail shape or a T-shape.

[0018] Depending on the structural height, the narrow side can form the longitudinal side of the main side, where the end region shows the short side. The directional terms "height" and "width" refer to the receiving space and currently indicate the direction in a cross-sectional plane perpendicular to the longitudinal direction of the energy guide chain. Currently, "horizontal" means in the direction of the width of the receiving space, and "vertical" means in the direction of the height of the receiving space, regardless of the actual, spatial orientation of the chain links. The terms "up" and "down" should not be understood as absolute, but rather to refer to exemplary spatial arrangements and are interchangeable for this purpose. Currently, the terms "parallel" and "vertical" should be understood technically rather than strictly geometrically. Minor deviations from geometric parallelism with small angular dimensions are also understood as parallel.

[0019] To avoid the force required for locking the grid bottom in a force-locking manner, a preferred embodiment includes a locking slider that is movable in the height direction between a locked and unlocked position within the receiving portion of the base and has locking elements, each of which is associated with a retaining groove. Each locking element can move into its associated retaining groove to engage securely with the grid bottom (particularly with the recesses on the end side of the grid bottom). Preferably, all necessary locking elements are disposed on the same locking slider, such that the number of locking elements is commensurate with the total number of retaining grooves.

[0020] Here, each locking element preferably functions as a locking element or a blocking element in conjunction with a recess on the grid bottom that serves as a collector for locking elements.

[0021] For example, a locking slider can be centrally located for retaining grooves on both main sides, with a locking slider for the retaining groove on each main side. Alternatively, a common locking slider can be provided on each of the two main sides on the two narrow sides to block the end portions of the grid bottom. Therefore, the locking device can essentially consist of a locking slider centrally located within the base. In a particularly preferred embodiment, a common, centrally located locking slider is provided for the retaining grooves on both main sides. Here, the plate-like base can comprise two plate portions, preferably identical in structure or manufactured as identical pieces, each plate portion forming a plurality of continuous retaining grooves on its outer side and a slot for the locking slider on its inner side. The plate portions can be interconnected by suitable connecting elements, particularly by conjugate connecting elements or by snap fasteners, etc.

[0022] To further simplify operation, the locking slider may have at least one actuating protrusion protruding on a narrow side of the base, allowing for simplified manual operation similar to a sliding button. Preferably, operability on both sides is also achieved here by having two opposing, preferably symmetrical, actuating protrusions protruding on one of the narrow sides of the base. Here, the actuating protrusions can form sliding buttons on their end sides.

[0023] The locking slider is preferably implemented as a single piece with the bolt element and, if necessary, as a single piece with the operating protrusion.

[0024] In another embodiment, the locking device has two locking sliders. These locking sliders are movable in the height direction between a locked position and an unlocked position in the receiving portion of the base and have locking elements, such as locking elements corresponding to the number of retaining slots. Here, each locking element is also preferably associated with a retaining slot and movable within this retaining slot to securely cooperate with the grid bottom (e.g., a recess on the end side). In this embodiment, the base can have two receiving portions that are offset perpendicular to the height direction for corresponding to one locking slider. Here, one of the two receiving portions, or the locking slider supported therein, can be provided on each main side.

[0025] In all embodiments having one or more locking sliders, it is advantageous that each locking slider, in the unlocked position, protrudes along the height direction in the upper or lower end region of the base with an end protrusion. This achieves, and ensures, by closing the transverse slats: the locking slider moves into the locked position, i.e., in the case of closed transverse slats and links, securing the base to prevent undesirable loosening. Thus, it also blocks or prevents undesirable unlocking in the case of closed links (with transverse slats fitted on both sides), since unlocking is only possible when the transverse slats are open. Preferably, the locking slider is configured such that it can protrude alternately beyond the upper and lower end regions with the end protrusion, depending on which transverse slat is open (inner radius or outer radius), and has a suitable structural height.

[0026] However, a suitable locking device does not necessarily have to be implemented as a locking device with a sliding element. In a simple, alternative embodiment, the locking device can have cooperating locking elements. For example, cooperating locking recesses and / or locking protrusions can be provided on the retaining groove and the end region of the grid bottom into which they are inserted. Here, it is preferable to provide at least one locking recess and / or locking protrusion on each retaining groove for engaging with the locking element on the corresponding conjugate end side of the grid bottom. Supplementally or alternatively, a spring-loaded locking tongue is also considered as a locking element, preferably a locking tongue on the end of the grid bottom. The locking tongue can cooperate with the corresponding locking edge (e.g., the locking recess) at the limiting interface of the locking groove. In particular, spring-loaded locking tongues or locking hooks can be provided on both sides of the end area of ​​the grid bottom that is embedded in the locking groove. The locking tongues or locking hooks work together with the corresponding locking edges on the limiting interface of the locking groove, for example in the form of barbs, to block or lock the grid bottom to prevent unwanted loosening in the longitudinal direction, and are ineffective when being moved in.

[0027] To ensure a secure, shape-locking hold in the horizontal direction, or perpendicular to the main plane, the retaining grooves on both main sides each have a T-shaped cross-section perpendicular to the main plane, so as to work in conjunction with corresponding protrusions at the ends of the grid base to retain the grid base. Alternatively, a dovetail-shaped or similar cross-section can be provided instead of a T-shaped cross-section.

[0028] Preferably, the retaining grooves extend parallel to each other and are perpendicular to the height direction, extending continuously from one narrow side to the other. Preferably, the retaining grooves are arranged in pairs on each main side, facing away from each other, at the same height, but this is not mandatory. Currently, the so-called side members used to abut against the side plates (i.e., those with retaining grooves on one side) are also understood to be dividing strips.

[0029] Preferably, the two end regions of the base have fastening devices to be loosely fastened to the upper and lower transverse slats by force locking and / or shape locking. Here, at least one end region, preferably both end regions, can be implemented as locking feet for locking with transverse slats in a structural form known per se.

[0030] Preferably, the substrate is configured to be mirror symmetrical about its height center plane, such that the end regions can be interchanged at the top and bottom, and this orientation is not important during assembly.

[0031] Due to the equal operability on both sides, it is preferable to set various symmetrical characteristics of the dividing strips.

[0032] Preferably, the substrate is configured to be mirror-symmetrical about its principal plane, which is particularly advantageous when a common sliding or locking element is used on both principal sides. Alternatively, the substrate can be configured to be axisymmetric about its height center axis, for example, if each principal side has its own sliding or locking element.

[0033] This invention is particularly advantageous when there is a finely segmented internal division with a relatively large number of positions for the grid base, i.e., if at least five retaining slots are provided on each main side, a wide range of options are available. Especially when using locking sliders, all introduced grid bases can be locked and unlocked simultaneously with a single operation.

[0034] To further simplify the setup, each retaining groove has two inlet openings with opposing, end-side inlet ramps or inlet chamfers. Such inlet ramps or inlet chamfers can be arranged in pairs on both sides in a mirror-symmetrical arrangement about the longitudinal axis of the retaining groove.

[0035] The present invention also relates to a link for an energy steering chain, the link comprising two side plates and at least one transverse strip, the at least one transverse strip connecting the side plates to define a receiving space for a conduit, wherein the link has two or more dividing strips according to the invention and at least one grid base held at the end by these dividing strips respectively. The present invention also relates to an energy steering chain comprising a plurality of links, wherein at least every second link has dividing strips according to the invention. Furthermore, the present invention relates to a kit for internal partitioning of links in an energy steering chain, the kit comprising at least two dividing strips according to the invention and at least one corresponding grid base, and the last page of the invention relates to an application of dividing strips according to the invention for internal partitioning in an energy steering chain.

Detailed Implementation

[0037] Figure 1 and Figure 2A An exemplary internal structure of a link 10 of an energy guiding chain 1, shown in an exploded view or previous view, is illustrated. This energy guiding chain is used to actively guide conduits, such as cables and hoses (not shown). Multiple links 10 are perpendicular to... Figure 2A The links 10 are interconnected in a swingable manner along the longitudinal direction L of the plane to form an energy guiding chain 1. The longitudinal direction L corresponds to the longitudinal extension of the guided conduit. Here, the link 10 is composed of a single piece and has at least two side plates 11. In each or, for example, every second link 10, the side plates 11 (as shown in Figures 1 and 2A) are box-shapedly fixedly connected by two parallel, identical transverse strips 12, spaced apart in the transverse direction Q perpendicular to the longitudinal direction L of the link 10 and kept parallel to each other.

[0038] In the illustrated embodiment, the transverse slat 12 is detachable (so-called open slat). For this purpose, the transverse slat 12 is secured by a fastening region on its end side, for example by means of the corner 110 on the side plate 11 (in... Figure 1 The clamping receiving part (shown in the middle) is fastened to the side plate 11 in a way that allows it to loosen or swing. The transverse slats 12 of the link 10 are spaced apart from each other in the height direction H. The height direction H runs perpendicular to the longitudinal direction L and perpendicular to the transverse direction Q. The side plate 11 and the transverse slats 12 define a receiving space 14 for the pipeline to be guided. Therefore, the two transverse slats 12 can be implemented as open slats to allow access to the receiving space 14 in the open state.

[0039] The energy guide chain 1 consists of multiple links 10 that are oscillatingly connected to each other in the longitudinal direction L. When guiding the pipeline between two relatively movable connection points, the energy guide chain 1 can form an upper segment, a lower segment, and a segment (i.e., a steering arc) that bends around the steering axis between them. The structure of the energy guide chain 1 itself is known and can be arbitrary, for example, having bent side plates or having alternating inner and outer plates as side plates 11. In particular, a two-piece link is considered, in which the two side plates 11 and the transverse slats 12 are manufactured from a single block, i.e., manufactured in one piece, and only the other transverse slat 12 is detachable (not shown).

[0040] For the purpose of internal partitioning, it is known that, as in Figure 2A As exemplarily shown, vertical dividing strips 20 are provided for dividing the receiving space 14 in the lateral direction Q and horizontal grid bases 18 are provided for dividing the receiving space 14 in the vertical direction H.

[0041] The dividing slats 20 typically have a plate-like or flat base 13 with a main plane that runs parallel to the side plates 11 in the longitudinal direction L and the height direction H in the predetermined assembly state of the dividing slats 20 in the link 10. The grid bottom 18 is similarly constructed as a plate and runs parallel to the transverse slats 12 in the link 10 in the predetermined assembly state. The dividing slats 20 and the grid bottom 18 can be arranged in the same manner on every nth link 10, especially on every second link 10, so that the receiving space 14 can be set as a constant compartment or grid 140 for orderly and better protected guidance of the pipeline. Figure 2A The illustrations shown here are merely exemplary and simplified; typically, additional dividing strips 20 and additional grid bases 18 are provided.

[0042] The dividing slat 20 has two end regions 16a and 16b in the height direction H, each with a corresponding fastening device (here, a corresponding clip-shaped locking foot 160). These end regions 16a and 16b can be fastened to one of the end regions 16a and 16b on the end side 23 of the transverse slat 12 at selectable positions in the transverse direction Q, or in the length direction of the transverse slat 12, and in the longitudinal direction L, for example, by a locking connection. The transverse slat 12 can have a rack along its end side 23, as in… Figure 1 As shown, it is used in conjunction with the locking feet 160 of the dividing slats 20. The transverse slats 12 are locked at least in the longitudinal direction L of the link 10, or in the direction of the width of the transverse slats 12.

[0043] The grid base 18 can be placed on the dividing strip 20 in a selectable step with respect to the height direction H. Figure 1 and 2A This example exemplarily shows only one grid base 18, which divides a portion of the receiving space 14 between two dividing slats 20. The base 13 of the dividing slats 20 also has two opposing main sides 15 and two opposing narrow sides 17, the main sides being parallel to the main plane orientation, and the narrow sides extending perpendicularly to the main sides 15 in the height direction H from an upper end region 16a to a lower end region 16b. The base 13 has a plurality of identically configured retaining grooves 19 on its main sides 15 to receive the grid base 18. The retaining grooves 19 extend parallel to each other and perpendicularly to the height direction H from one narrow side 17 to the other. Each retaining groove 19 opens into a corresponding inlet opening 170 at each narrow side 17. Thus, the correspondingly shaped ends of the grid base 18 can enter into the corresponding retaining groove 19 of each narrow side 17, i.e., can be moved in and out in each of the two assembly directions along the longitudinal direction L.

[0044] Figure 3The first embodiment of the dividing slats 30 is shown in an exploded view. To secure the grid bottom 18 and prevent unwanted movement in the longitudinal direction L and accidental loosening from the retaining groove 19, the dividing slats 30 have a locking device with a locking slider 31.

[0045] The dividing strip 30 has a base 33, which is in the principal plane (see...) Figure 2A The WW in the diagram is mirror-symmetric and consists of two identical plate portions 33a. Similarly, each of the plate portions 33a is symmetrical about a height-central plane perpendicular to the principal plane. Furthermore, each of the two structurally identical plate portions 33a is symmetrical about a central axis point, which serves as... Figure 3 The dashed line in the middle passes through the center of symmetry in the two plate sections 33a.

[0046] The plate portion 33a has an outer side 35 and an inner side 36 opposite to the outer side 35. The outer side forms one of the main sides 15 of the base and has a retaining groove 19. The inner side has a locking protrusion 37a and a corresponding recess 37b, serving as a connecting element for locking with the second plate portion 33a to form the base 33. The inner side 36 also has a cross-shaped slot 32. If the two plate portions 33a are combined to form the base 33, the slot 32 forms a receiving portion 34 for locking the slider 31, so that the locking slider 31 can be centrally received in the base 33.

[0047] The locking slider 31 is supported in the receiving portion 34 of the dividing strip 30 in a manner movable between a locked position and an unlocked position in the height direction H. Figure 3 In the embodiment shown, the locking slider 31 is implemented in a cross shape, having a vertical beam 311 extending in the height direction H and a horizontal beam 312 perpendicular to the vertical beam 311. Currently, the terms "vertical" and "horizontal" refer to the predetermined position of the locking slider 31 within the link 10, where vertical means along the height direction H and horizontal means along the longitudinal direction L. Spatially oriented energy varies depending on the position of the link, or energy guiding chain.

[0048] The locking slider 31 has actuating protrusions 38 at each end of the horizontal beam 312, which are ergonomically shaped for manual movement of the locking slider 31 between an unlocked and a locked position. When the locking slider 31 is fitted between the two plate portions 33a of the base 33, the two actuating protrusions protrude from the narrow side 17 of the base 33. For this purpose, the slot 32 is also cross-shaped and passes into the narrow side 17.

[0049] The vertical beam 311 has a row of locking elements 39 in the form of block-shaped protrusions on both sides, the number of which corresponds to the number of retaining grooves 19 on the corresponding main side. The locking elements 39 protrude in a direction perpendicular to the main plane and are arranged with the same vertical grid spacing as the retaining grooves 19. The locking slider 31 and the locking elements 39 are made into a one-piece injection molded part.

[0050] When the locking slider 31 is in the locked position, the bolt element 39 extends into the corresponding retaining groove 19 and is positioned approximately in the center there.

[0051] Figure 4A , 4B The grid base 18 is shown, which is plate-shaped and longitudinally elongated, having an extension in the transverse direction Q between its ends 48. Figure 4B In the end-side view, each end 48 has an end-side protrusion 48a that extends in the longitudinal direction L and complements the profile of the retaining groove 19, which is T-shaped in the illustrated embodiment, for moving the end 48 into the retaining groove 19. Alternatively, it could be another, for example, dovetail-shaped profile of the retaining groove 19 and the end 48 of the grid base 18. This profile secures the moved-in grid base 18 in the transverse direction Q perpendicular to the main plane of the dividing strip 30.

[0052] To secure the grid base 18 in the longitudinal direction L (i.e., in the longitudinal direction of the retaining groove 19), each end of the grid base 18 has a recess 46 for cooperating with the corresponding latching element 39. For the end 48 of the grid base 18 to be moved into the retaining groove 19, the locking slider 31 must be in the unlocked position. When the end 48 of the grid base 18 is received in the retaining groove 19, the locking slider 31 can move to its locked position, in which the latching elements 39 extend into the retaining groove 19 and engage with the recesses 46 on the end side of the grid base 18. In this position, the grid base 18 is fixed or locked to the dividing strip 30 in the longitudinal direction L and cannot move along the retaining groove 19 or can only move slightly.

[0053] Figure 5A and 5B (and respectively as magnified local areas) Figure 6A and 6B A side view along the longitudinal direction L shows the unlocked position ( Figure 5A , 6A ) and lock position ( Figure 5B , 6B The dividing strip 30 of the locking slider 31 in the lock. The retaining groove 19 is free in the unlocked position to move into the bottom of the grid 18, while in the locked position, the retaining groove 19 is blocked by the associated bolt element 39.

[0054] Figure 7A A side view along the longitudinal direction L shows a dividing strip 30 with a grid bottom 18 that moves into a retaining groove 19 and a locking slider 31 in the locked position. Figure 7B The cross-section of the principal plane of grid base 18 is shown, which extends in the longitudinal direction L and the transverse direction Q. Let's take a look. Figure 7A and 7B As can be seen best, the grid bottom 18 is secured on the one hand by the T-shaped profile of the retaining groove 19 to prevent movement in the height direction H and the lateral direction Q, and on the other hand by the shape-locking engagement between the recess 46 of the grid bottom 18 and the corresponding bolt element 39 of the locking slide 31 to prevent movement in the longitudinal direction L.

[0055] The locking slider 31 is constructed to be both point-symmetric and mirror-symmetric, each having three planes of symmetry. Thus, it can lock the grid base 18 to both sides of the dividing slats 30 and can be unlocked in two directions along the vertical. This is particularly advantageous in links 10 where the two transverse slats 12 are implemented as open slats. Therefore, the locking slider 31 can be unlocked on each of the transverse slats 12 as needed.

[0056] The locking slider 31 can be moved from the locked position to the unlocked position in two directions along the height direction H. In addition to displacement by manipulating the protrusion 38, locking can also be achieved by pressing the vertical beam 311. For this purpose, end protrusions 82 are formed at the ends of the vertical beam 311, which protrude from the base 33. In the unlocked position of the locking slider 31 received in the base 33, depending on which direction along the height direction H the locking slider 31 is moved to unlock, one of the end protrusions 82 protrudes from the base 33, such as... Figure 8A As shown, by moving the end protrusion 82 upward as shown, the locking slider 31 moves into the locked position. This can be achieved, in particular, by closing the opened transverse slat 12. This prevents the unlocked dividing slat 30 from remaining in the closed, ready link 10, or from causing self-locking.

[0057] Figures 9A to 11C Another, second embodiment of the dividing slat 90 is shown. The difference from the dividing slat 30 is that the base 93 of the dividing slat 90 can be manufactured in one piece. For example... Figure 10AAs shown, the one-piece base 93 is plate-shaped and has two opposing main sides 95 and two opposing narrow sides 97. The main sides run parallel to the main plane, and the narrow sides extend perpendicularly to the main sides 95 in the height direction H from the upper end region 16a to the lower end region 16b. Similar to the embodiment described above, the end regions 16a, 16b are equipped with locking feet 160. The base 93 has a plurality of identical retaining grooves 19 on its main sides 95 to receive the grid bottom 18. The retaining grooves 19 extend parallel to each other and perpendicularly to the height direction H from one narrow side 97 to the other. Each retaining groove 19 opens at each narrow side 97 into one of the two end side inlet openings 170. The corresponding profiled end of the grid base 18 can be moved into the corresponding retaining groove 19 of each narrow side 97, that is, it can be moved in and out in each of the two assembly directions along the longitudinal direction L or along the width of the dividing strip 90 and the grid base 18.

[0058] exist Figures 9A to 11C In this design, the dividing strip 90 has two locking sliders 91 for securing the inserted grid base 18 in the retaining groove 19, with one locking slider corresponding to each main side 95 of the base 93. Each of the locking sliders 91 is movable along the height direction H in a corresponding receiving portion 94. The receiving portion 94 is configured as a recessed portion on the corresponding main side 95 of the base 93. The base 93 has central symmetry, allowing the dividing strip 90 to be inserted by twisting 180° about the height direction H, the longitudinal direction L, or the transverse direction Q.

[0059] Here, the two locking sliders 91 are identical. (As in...) Figure 10B As shown, the locking slider 91 has the shape of a longitudinally elongated strip or beam with a plurality of locking elements 99, which are constructed as protrusions. In the unlocked position of the locking slider 91, as in... Figure 9A In or as Figure 11A As shown in the detailed section, the protrusion or locking element 99 is located between the retaining grooves 19 with respect to the height direction H, so that the end of the grid bottom 98 can be moved into or out of the retaining groove 19.

[0060] The grid base 98 is plate-shaped and has T-shaped protrusions 98a at its ends, corresponding to the profile of the retaining groove 19, to function in conjunction with the retaining groove 19. As another difference from the first embodiment, the respective ends of the grid base 98 do not have two recesses 96 for receiving the locking elements 99. Therefore, the grid base 98 can be configured as mirror symmetrical. The distance between the respective recesses 96 and the respective longitudinal narrow sides of the grid base 98 in the longitudinal direction L corresponds to the distance between the corresponding receiving portion 94 and the closest narrow side of the base 93. An embodiment is also conceivable that does not have recesses 96 in the grid base but has end-side locking portions on the two end edges.

[0061] When the locking slider 91 in the receiving section 94 is shifted or moved into the locking position in the height direction H, such as in Figure 9B Or rather Figure 11B (Without a base) or Figure 11C As shown, the locking element 99 extends perpendicularly to the main side 95 into the retaining groove 19. In this locked position of the slider, the base 98 is secured to prevent unwanted movement along the retaining groove 19.

[0062] Figures 12A-13B Another embodiment of the dividing strip 120 is shown, which is manufactured in one piece but does not have a locking slider. As in the embodiment shown above, the dividing strip 120 also has a symmetrical, plate-like base 123 with two main sides 125 and two narrow sides 127. Each of the main sides 125 has a row of profiled retaining grooves 19 to receive and form-lock the ends 128a of the grid base 128. In this embodiment, the retaining grooves 19 also extend continuously from one narrow side 127 to the other and are open or accessible on both sides, i.e., in the introduction openings 170 on each of the narrow sides 127. The grid base 128 has protrusions at its ends that correspond to the profile of the retaining grooves 19 and extend in the longitudinal direction L. Here, the grid base 128 inserted into the retaining grooves 19 is secured by a locking latching element to prevent movement along the retaining grooves 19. For this purpose, a locking cam 124 is constructed on the end 128a of the base 128, which engages with a corresponding locking recess 122 on the main side 125 of the base 123. An inverted configuration with a locking cam on the base is also conceivable.

[0063] The link 10 and all the components described above, especially the dividing strips 20, 30, 90, 120, are preferably manufactured as plastic parts by injection molding.
