Description

Suspension rail and method for manufacturing an integrated suspension rail [OOO1] The present disclosure relates to a suspension rail integrated into a carrier plate and to a method for manufacturing a suspension rail integrated into a carrier plate. Furthermore, the present disclosure relates to such a suspension rail with an integrated light strip.

[0002] From EP 0 891 858 A2, a sandwich panel with an integrated profile for fastening purposes is known, which is particularly suitable for use in vehicle construction. The profile is integrated into the sandwich panel starting from a front side, so that on the one hand a large area of ​​coverage is required and on the other hand any tensile loads are only inadequately absorbed by the sandwich panel.

[0003] Hanging rails are used, for example, to attach curtains, drapes, privacy screens, sunshades, and the like to walls or ceilings. Hanging rails can also be used, in principle, to hang pictures, mirrors, and the like. This disclosure specifically relates to hanging rails used in residential buildings, office buildings, retail stores, and the like.

[0004] Hanging rails are designed, for example, as curtain tracks, drapery rails, and the like. An exemplary design of a curtain track is known from DE 20 2011 105 092 U1. Hanging rails typically comprise a profile rail with at least one receiving groove into which gliders, rollers, or similar components are inserted to secure an object to be hung.

[0005] Suspension rails, for example, are designed as surface-mounted rails, meaning they can be placed on an existing wall or ceiling surface as a separate element and attached there.

[0006] This is often satisfactory from a functional point of view, but not from an aesthetic one. Integrated, ideally invisible designs are frequently perceived as high-quality. Such a "recessed" arrangement of a suspension rail is often only achievable with considerable effort or is simply impossible due to structural reasons.

[0007] Against this background, the present disclosure aims to provide a method for manufacturing a suspension rail integrated into a carrier plate, and such a suspension rail itself, which allows for an aesthetically pleasing, virtually invisible design. In particular, the suspension rail should be easily integrated into a given room design, for example, by incorporating a specific color scheme (painting) or a specific surface finish. Furthermore, the suspension rail should be installable with minimal subsequent effort (labor, mess, etc.) after any drywall work or similar construction.

[0008] According to a first aspect, the present disclosure relates to a method for manufacturing a suspension rail integrated into a carrier plate, comprising the following steps: Provision of a carrier plate having a front and a back, wherein the carrier plate has a thickness between the front and the back, Provision of a profile rail with a receiving groove, machining of the carrier plate from the back to create a receiving profile for the profile rail, wherein the receiving profile extends from the back to the front and ends at least partially in front of the front, so that a thin-walled wall section remains in front of the receiving groove, Inserting the profile rail into the receiving profile of the carrier plate, and Joining the profile rail to the carrier plate, in particular by bonding, wherein the receiving groove faces the front, and wherein the carrier plate covers the receiving groove at least partially on the front.

[0009] This allows for a visually appealing, integrated design, resulting in a minimalist ("clean") aesthetic. The time required to install such an embedded suspension rail is significantly reduced compared to retrofitting it into existing structures. The suspension rail is particularly suitable for integration into plasterboard and similar building panels or cladding boards. The profile rail is designed, for example, as an extruded profile made of an aluminum alloy. Plastic profiles are also conceivable. The profile rail is, for instance, manufactured using an extrusion process.

[0010] The groove for the mounting plate is intentionally designed so that it does not initially extend completely through the carrier plate. In other words, the profile rail is not necessarily visible from the front of the carrier plate at first. Access to the mounting groove can be created later. This allows the front of the carrier plate to be completely painted over, and the thin section of wall in front of the mounting groove can be removed later.

[0011] In one exemplary design, only a small slit is visible from the front after access to the receiving groove has been provided. The support structure is largely invisibly integrated into the carrier plate.

[0012] The joining process includes, for example, joining by adhesive bonding. The remaining wall thickness of the thin-walled wall section is, for example, less than 1.0 mm. In one exemplary embodiment, the remaining wall thickness is less than 0.5 mm. In another exemplary embodiment, the remaining wall thickness is approximately 0.3 mm.

[0013] A concealed suspension rail integrated into a mounting plate can initially be installed "as a precaution" in a building. The profile rail with its integrated groove can remain completely invisible at first. The front of the mounting plate can, for example, be painted or otherwise decorated. If a suspension rail is required later, the groove can be made accessible by removing at least part of the thin-walled section. This significantly reduces the workload and mess compared to retrofitting / attaching suspension rails.

[0014] It goes without saying that a mounting plate can have one or more profile rails. For example, combinations of curtains, drapes, and / or sun protection elements often require several parallel mounting grooves. Accordingly, multiple profile rails can be integrated into a single mounting plate. If only a subset of the mounting grooves is needed initially, it is not necessary to expose all of them.

[0015] According to another exemplary embodiment, it is provided that single-track (one receiving groove) and multi-track (two, three or more parallel receiving grooves) systems can be realized with only one type of profile rail when the corresponding number of profile rails is integrated into a carrier plate.

[0016] According to an exemplary embodiment, the method further comprises the step of removing at least part of the thin-walled wall section after the joining step, so that an access slot of the receiving groove becomes accessible. In this way, a continuous access slot can be created along the longitudinal extent of the profile rail.

[0017] The thin-walled section of the wall is removed to provide access to the receiving groove. This can be done immediately after the joining step. However, it is also conceivable to remove the thin-walled section of the wall much later. This could, for example, only be done once the carrier plate with the integrated receiving rail has been installed in a building.

[0018] In other words, the carrier plate can be coated on its front side, for example with wall paint or ceiling paint, wallpaper, or similar. Afterwards, the thin wall section in front of the access slot can be selectively removed.

[0019] According to another exemplary embodiment, the step of removing at least part of the wall section comprises pulling out a strip inserted into the receiving groove, the strip removing the wall section as it is pulled out through the access slot. The strip can be described, for example, as a perforation strip. The strip is adapted, for example, to the width of the access slot in order to expose it across its entire width. The strip itself serves as a tool for removing the thin-walled wall section.

[0020] According to another exemplary embodiment, the step of removing at least part of the wall section comprises separating the wall section with a cutting tool that engages the support plate from the outside at the front. The cutting tool could be, for example, a knife. By way of example, the cutting tool is designed as a double knife with parallel blades whose spacing is adapted to the width of the access slot. By way of example, the cutting tool is a milling cutter whose working width is adapted to the width of the access slot.

[0021] In another exemplary embodiment, the carrier plate is a gypsum board, which, together with other gypsum boards, can be mounted on a wall or ceiling to provide an integrated suspension rail. In this way, the integrated suspension rail can be installed quickly and easily thanks to its carrier plate. Flush integration into existing wall and / or ceiling designs can be achieved. A gypsum board typically has a paper facing on both sides. Therefore, even with a thin remaining wall section, good coverage of the mounting groove on the front is ensured. The strength of the gypsum board is not compromised if the profile rail is properly joined to the carrier plate, for example, by bonding it with adhesive over a large area.

[0022] In another exemplary embodiment, the profile rail has lateral support legs on the back of the mounting plate, which are recessed into the receiving profile, resulting in a flat back surface of the mounting plate. This allows the suspension rail to bear high loads. The lateral support legs rest on the mounting plate in an area where the plate is not excessively weakened by the receiving profile. In this example, the receiving profile also provides a recess for the lateral support legs. This results in a flush finish on the back of the mounting plate as well. The lateral support legs of the profile rail can also be used to create a material-fit connection between the profile rail and the mounting plate.

[0023] According to another exemplary embodiment, a support strip, designed in particular as a fabric strip, is attached to the back of the carrier plate, covering at least the profile rail and two sections of the carrier plate adjacent to the profile rail. The support strip can be combined with the lateral bearing legs of the profile rail to create a firm connection between the carrier plate and the profile rail, and to increase the overall strength of the integrated suspension rail thus produced.

[0024] The support strip can be bonded to the back of the carrier board, for example, with a material-bonded connection, and additionally to the profile rail if required. The support strip is preferably sufficiently thin to ensure continued good workability of the carrier board, for example, when combined with other adjacent gypsum plasterboard panels.

[0025] According to a further exemplary embodiment, the method also includes inserting a guide rail, made in particular of a plastic material, into the receiving groove, wherein the guide rail has an open profile with the opening facing the front. The guide rail can be inserted into the receiving groove to minimize friction during the movement of objects (curtains, drapes, sunshades, and the like) held in the suspension rail. The guide rail can increase the service life of the suspension rail. The guide rail can be designed as a wear part and be replaceable.

[0026] According to another exemplary embodiment, the guide rail has a handle for disassembly purposes on a profile base facing the rear. In this way, the guide rail can be selectively removed from the receiving groove of the profile rail without damaging the integrated receiving rail.

[0027] According to a further exemplary embodiment, the profile rail has, in addition to the receiving groove, at least one fitting recess extending at least partially parallel to the receiving groove, wherein two profile rails facing each other end-to-end are joined by inserting a connecting pin into the at least one The recesses of the two profile rails are aligned and connected. This ensures precise alignment of adjacent support plates during the installation of the mounting plate with the integrated suspension rail. This allows the guide length of the suspension rail(s) to be increased as needed.

[0028] For example, the profile rail has two locating recesses between which the receiving groove is formed. In this way, two adjacent profile rails can be precisely aligned with each other in several axes.

[0029] According to another exemplary embodiment, the connecting pin is at least partially conical. This has the advantage that the connecting pin cannot penetrate arbitrarily deep into the fitting recess when inserted. This prevents the connecting pin from being pushed completely into one of the two profile rails when two adjacent profile rails are brought into close proximity.

[0030] In another exemplary embodiment, the profile rail extends along a curved path. This allows for the provision of curved sections. For example, a 90° deflection is achieved in this way, where the end faces of the profile rail are offset from each other by 90°. Similar to the otherwise straight profile rails, the curved profile rail can also be made of metal (e.g., aluminum profile), plastic, or similar materials. By providing curved sections, various configurations and designs of suspension rails can be realized.

[0031] According to another exemplary embodiment, the procedure further comprises the following steps: Provision of a light strip comprising a longitudinally extending profile made of a soft plastic, in particular a closed profile with a rectangular cross-section, which is at least partially transparent, adapted to a depth of the receiving groove and a width of the access slot. and features a plurality of light sources arranged in a series along a longitudinal extension of the light strip, and Insert the light strip through the access slot into the receiving groove, with one front side of the profile adjacent to the front side of the carrier plate being flush with the front side of the carrier plate.

[0032] This expands the range of applications for the suspension rail. The suspension rail can be used to provide aesthetically pleasing lighting.

[0033] The soft plastic used is, for example, a silicone material, rubber, TPE, or similar. The profile of the light strip is intentionally designed with a slight oversize compared to the width of the access slot, so that the light strip adheres automatically to the groove. The light strip is sufficiently flexible to allow for curves and similar shapes.

[0034] The light strip can be purchased by the meter, for example, and extended across adjacent plasterboard panels with an integrated hanging rail. This creates a high-quality, seamless look.

[0035] According to a further aspect, the present disclosure relates to an integrated suspension rail comprising: a carrier plate having a front and a back, wherein the carrier plate has a thickness between the front and the back, and a profile rail with a receiving groove, wherein the profile rail is inserted into a receiving profile produced by machining the carrier plate from the back and joined there to the carrier plate, wherein the receiving profile extends from the back to the front and terminates at least partially in front of the front, leaving a thin-walled section in front of the receiving groove. wherein the receiving groove faces the front, and wherein the support plate on the front at least partially covers the receiving groove, so that an access slot of the receiving groove is concealed.

[0036] It is understood that the manufacturing process and the suspension rail disclosed may be further developed by means of identical or similar features. The embodiments described within the scope of this disclosure can be applied to both the manufacturing process and the suspension rail disclosed.

[0037] It is understood that the features of the disclosure mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present disclosure.

[0038] Further features and advantages of the present disclosure will become apparent from the following description of several preferred embodiments with reference to the drawings. These show: Fig. 1 : a front view of a suspension rail integrated into a support plate; Fig. 2: a front-end partial view of a support plate, which is ready for the integration of a profile rail to form a suspension rail; Fig. 3: a front-end partial view of a carrier plate into which a receiving profile has been inserted; Fig. 4: an exploded end-face view of a carrier plate and a profile rail, before a joining process; Fig. 5: a front view of a receiving rail integrated into a carrier plate with a closed front in front of the receiving groove and with a rear support band; Fig. 6: an end-face view of a receiving rail integrated into a carrier plate to illustrate the removal of a thin-walled wall section to provide access to the receiving groove; Fig. 7: an end-face view of a profile rail with inserted running rail and a rollable object carrier arranged there; Fig. 8: another view based on Fig. 7 without the inserted rolling slide; Fig. 9: a front view of an integrated suspension rail with support plate; Fig. 10: another view, based on Fig. 9, of an integrated mounting rail with two parallel profile rails; Fig. 11: another view, based on Fig. 9, of an integrated mounting rail with three parallel profile rails; Fig. 12: a partial view of the front of two adjacent plasterboard panels with integrated suspension rail, which are joined together; Fig. 13: an enlarged view of a connecting pin for connecting adjacent suspension rails; Fig. 14: a view of a front side of a plasterboard panel with integrated suspension rail with curved profile rail to provide an arc, to connect two suspension rails offset by 90°; Fig. 15: a front-end sectional view of a light strip that can be inserted into a suspension rail; and Fig. 16: a front view of a mounting rail integrated into a carrier plate with an inserted light strip.

[0039] Fig. 1 illustrates a partial view of an end face of an integrated suspension rail 10. The suspension rail 10 comprises a support plate 12 (only partially shown in Figures 1-6) into which a profile rail 14 is inserted. The profile rail 14 forms a receiving groove 16, which is accessible via an access slot 18.

[0040] Fig. 2 shows the carrier plate 12 in its unprocessed state. The carrier plate 12 is designed, for example, as a plasterboard panel. The carrier plate 12 comprises a front 20 and a back 22. The carrier plate 12 has a thickness 26 between the front 20 and the back 22.

[0041] Fig. 3 illustrates, based on Fig. 2, a machined state of the carrier plate 12. Starting from the back side 22, the carrier plate 12 was machined to form a receiving profile 24. The machining can include, for example, milling, grinding, and similar processes. The receiving profile 24 extends from the back side 22 towards the front side 20. However, the receiving profile 24 does not completely sever the carrier plate 12. Instead, a thin-walled section 28 remains, so that even after machining, the carrier plate 12 (initially) has a continuous front side 20 that is uninterrupted in front of the profile rail 14.

[0042] Fig. 4 illustrates a step in which the profile rail 14 (still in sections) is fed to the receiving profile 24 of the carrier plate 12. In the exemplary embodiment, the profile rail 14 has two support legs 30, 32 which, in the joined state, are associated with the back side 22 of the carrier plate 12. The joining of the profile rail 14 to the carrier plate 12 can be achieved, for example, by material bonding using an adhesive layer 34. In this way, despite the weakening of the carrier plate 12 by the insertion of the receiving profile 24, a sufficiently rigid and strong structure of the integrated suspension rail 10 can be ensured.

[0043] In Fig. 4, two locating recesses 36 and 38 are also indicated, adjacent to the receiving groove 16. The locating recesses 36 and 38 serve to align two profile rails 14 to be combined along their longitudinal extent. Each locating recess 36 and 38 can accommodate a connecting pin that can be inserted into the locating recesses 36 and 38 of two opposing profile rails 14 (see also Fig. 12 and Fig. 13).

[0044] Fig. 5 illustrates a state in which the suspension rail 10 has been created by joining the support plate 12 with the profile rail 14. The support plate In the state shown in Fig. 5, 12 is still closed at the front 20, compare the remaining thin wall section 28.

[0045] Fig. 5 further illustrates that a support strip 42 can optionally be used to additionally secure the assembly of the carrier plate 12 and the profile rail 14 on the rear side 22. The support strip 42 is, by way of example, a fabric strip that can be bonded to the rear side 22 of the carrier plate 12 and, if necessary, to the profile rail 14. In the embodiment according to Fig. 5, the width of the support strip 42 covers the width between the bearing legs 30, 32 of the profile rail 14, as well as the adjacent areas of the rear side 22 of the carrier plate 12.

[0046] Fig. 5 further illustrates that, in the exemplary embodiment, the profile rail 14 has inclined surfaces 46, 48 facing the front 20. Due to the inclination of the inclined surfaces 46, 48, the width of the thin-walled wall section 28 at the front 20 is reduced. The inclined surfaces 46, 48 together form a V-shape, the apex of which is interrupted by the access slot 18. On the one hand, the wall section 28 should be thin enough to be easily separated in a subsequent step. On the other hand, the structural and visual integrity of the support plate 12 at its front 20 should be maintained, regardless of whether the wall section 28 is closed or open. The inclined surfaces 46, 48 contribute to this.

[0047] Fig. 6 illustrates that the thin-walled wall section 28 can be separated from the front 20 of the support plate 12 to expose an access slot 18 to the receiving groove 16. The separation of the wall section 28 can be accomplished, for example, by means of a strip 50 extending through the receiving groove 16 along the longitudinal extent of the profile rail 14. The strip 50 can be pulled out from the front 20 (compare the arrow labeled 52), thereby separating the thin-walled wall section 28. It is understood that the wall section 28 can also be opened by other means, such as using a separate cutting tool. The cutting tool is, for example, a milling cutter, a knife, or a double knife with parallel-spaced blades adapted to the width of the access slot 18.

[0048] Additionally, Fig. 6 shows the integrated suspension rail 10 in a mounted state on a wall or ceiling 54, with its rear side 22 facing the wall or ceiling. The suspension rail 10 can be mounted directly on the wall / ceiling 54 with the mounting groove 16 open or concealed, or via a suitable support structure (drywall battens, laths, etc.).

[0049] Fig. 7 illustrates an end view of the profile rail 14, with a guide rail 60 inserted into the receiving groove 16. The guide rail 60 is made, for example, of a plastic material, optionally with a sliding coating. The guide rail 60 can also be referred to as an inlay. In the orientation shown in Fig. 7, the guide rail 60 comprises a downwardly open profile 62, the opening of which faces the access slot 18.

[0050] In the exemplary embodiment, the guide rail 60 carries rollers 64 on both sides within its profile 62. These rollers are supported on guide legs 70, 72 of the profile rail 14 via the guide rail 60. The rollers 64 support a support 66, only partially shown in Fig. 7, which, for example, holds a curtain.

[0051] Fig. 8 illustrates an exemplary embodiment of the guide rail 60, wherein a handle 76 is provided on a profile base 74 of the profile 62, which, in the assembled state, faces the rear side 22 of the support plate 12. The handle 76 can be accessed, for example, with a suitable tool (special pliers, pull hook, or the like) in order to pull the guide rail 60 out of the receiving groove 16 as needed. In this way, the guide rail 60 can be replaced if it becomes worn.

[0052] Figures 9, 10, and 11 illustrate various configurations of integrated suspension rails 10, 110, and 210, each comprising at least one profile rail 14 embedded in a gypsum board 80. The suspension rail 10 shown in Fig. 9 has a single profile rail 14. The gypsum board 80 forms the support plate 12, which carries the profile rail 14. The width of the support plate 12 is denoted by 82 in Fig. 9. In the exemplary embodiment, the width 82 of the support plate 12 is 280 mm, without this being to be understood as a limitation. The thickness 26 of the support plate is 12.5 mm in the exemplary embodiment, without this being to be understood as a limitation.

[0053] Fig. 9 illustrates that the profile rail 14 is deliberately not inserted centrally into the support plate 12. This makes the integrated mounting rail 14 suitable for various applications and installation conditions. Based on Fig. 9, Figs. 10 and 11 show configurations with more than one profile rail 14. The suspension rail 110 according to Fig. 10 has two parallel profile rails 14. The suspension rail 210 according to Fig. 11 has three parallel profile rails 14. This allows for multi-track configurations with several mounting grooves. It is conceivable to initially use only one of the profile rails 14 in the configurations according to Figs. 10 and 11 by providing the mounting groove 16 by removing the thin-walled section 28. This allows for the creation of additional mounting grooves 16 if needed later.

[0054] Fig. 12 shows a schematically simplified partial view of the front 20 of two suspension rails 10 with profile rails 14, which, as disclosed, are integrated into plasterboard panels 80. The profile rails 14 have locating recesses 36, 38 in which connecting pins 88 are seated. In this way, the two adjacent profile rails 14 can be aligned with high precision. Fig. 13 illustrates an exemplary embodiment of the connecting pin 88. In this embodiment, the connecting pin 88 is tapered towards its first end 90 and towards its second end 92. This prevents the connecting pin 88 from sliding completely into only one of the two profile rails 14 to be connected.

[0055] Fig. 14 shows a schematically simplified partial view of a front face 20 of several plasterboard panels 80 with profile rails 14 integrated according to the disclosure. In this way, a combined rail arrangement 94 is obtained from three suspension rails 10, 10', 10", according to the disclosure, which includes a 90° deflection. In Fig. 14, the reference numeral 96 denotes a curved path. A profile rail 14 can extend along the curved path 96 to form an arc. Thus, the end faces 98 of such a profile rail 14 are not parallel to each other, but offset by an angle. In this way, a connection / deflection between non-parallel profile rails 14 can be created. In particular, a 90° deflection is suitable for guiding curtains or the like around corners. This can also be achieved with integrated suspension rails produced according to the disclosure.

[0056] Fig. 14 further illustrates insertion openings, designated 84, in the respective receiving groove 16 of the profile rails 14. The insertion openings 84 simplify the installation and removal of curtains, drapes, and similar items. The insertion openings 84 have a width or diameter that is greater than the width of the access slot 18. The insertion openings 84 can be closed as needed to securely hold curtains, drapes, and the like in the receiving groove 16. The insertion openings 84 can be provided in the profile rails 14 "at the factory." However, it is also conceivable to subsequently create the insertion openings 84 as needed by drilling out or milling the access slot 18 of the profile rails 1.

[0057] Fig. 15 illustrates a profile 102 of a light strip 100 in a sectional view. The profile 102 comprises, for example, a soft plastic, such as a silicone-based material. In this way, the profile 102 and the light strip 100 formed by it are elastic and deformable. The profile 102 is designed, for example, as a hollow profile. Within the profile 102, a film strip 106 is formed, for example, which carries several light sources 104 (here in the form of LEDs) that are arranged in a row, offset from one another, along the longitudinal extension of the light strip 100 (perpendicular to the plane of view in Fig. 15). The profile 102 includes a transparent section 108, which is particularly more transparent than other areas of the profile 102.

[0058] Fig. 16 illustrates an embodiment in which the light strip 100 illustrated in Fig. 15 is inserted into the receiving groove 16 of the profile rail 14 of a suspension rail 10 produced according to the disclosure. The profile 102 of the light strip 100 is adapted to the receiving groove 16 with respect to its height and width and in particular- The profile 102 is adapted to the width of the access slot 18. Due to the sufficiently flexible design of the profile 102, the light strip 100 can be pressed into the receiving groove 16 and sit there automatically, even if its width is slightly greater than the width of the access slot 18. In this way, the integrated suspension rail 10 can also be used to provide lighting effects.
