Description

[0001] The present invention relates to a railing system and a method for assembling a railing system.

[0002] From EP 3 951 113 A1, a railing module is known, comprising a T-nut, a first profile, and stabilizing means arranged on the first profile. The first profile has a T-slot, wherein the T-nut can be inserted into the T-slot in a first orientation and can be positively locked in the T-slot from the first orientation to a second orientation by a rotation within the T-slot, or that the T-nut is profiled and can be slid into the T-slot.

[0003] German patent DE 10 2023 000 441 A1 discloses a railing system for mounting railing panels for privacy and wind protection and for fall protection on balconies, loggias or terraces. The railing system comprises a handrail with a handrail cover that completely conceals the tensioning screws used to tighten the railing panels.

[0004] The present invention aims to propose a railing system that has easy-to-assemble components and is aesthetically pleasing. A further objective is to propose a suitable method for assembling the components of the railing system. The railing system can, in particular, be a balustrade system, for example, for a balcony, a Juliet balcony, or a staircase.

[0005] A railing system is proposed as a solution, comprising: a base profile having a base section with several openings for fasteners, a first side with an outer bearing element and a second side with an outer positive locking element, wherein the outer bearing element and the outer positive locking element are oriented in opposite lateral directions from the base section;A mounting profile which can be detachably connected to the base profile in a way that overlaps the base profile, wherein the mounting profile has a first side wall section with an inner bearing element which can be brought into positive engagement with the outer bearing element of the base profile by lateral insertion, and a second side wall section with an inner positive locking element which can be brought into engagement with the outer positive locking element of the base profile by lateral displacement of the mounting profile in the opposite direction, wherein, in the engaged state of the positive locking elements, a recess is formed between the base section of the base profile and the projection of the mounting profile; and a locking element which can be inserted into the recess so that the mounting profile is secured against lateral movement relative to the base profile.

[0006] The locking element prevents the mounting profile from being pried out of the base profile. When installed, the mounting profile covers the base profile. The base profile is attached to a fixed component using fasteners, such as screws or other fasteners, which are inserted through the openings in the base profile and connected to the fixed component. This design places the fasteners within the profiles or conceals them within the mounting profile. This results in an attractive design with smooth surfaces, meeting high aesthetic standards. The two profiles can be connected or disconnected without screws using the locking element. When in use, the locking element prevents the mounting profile from being pried out.Therefore, it can also be described as an anti-levering device.

[0007] The overlapping or spanning arrangement of the mounting profile on the base profile justifies the designation of outer bearing element or outer positive locking element on the base profile, and inner bearing element or inner positive locking element on the mounting profile. The mounting profile is approximately U-shaped, with a first side section or leg, an opposing second side section or leg, and a base section connecting them. One of the side sections supports or encompasses the inwardly directed bearing element, and the other side section supports or encompasses the inwardly directed positive locking element. The base profile is essentially designed as an I-profile, with the bearing element and the positive locking element formed at the two ends, pointing in opposite directions away from the base section when viewed in cross-section through the profile.

[0008] For assembly, the mounting profile is placed onto the base profile and moved laterally, essentially perpendicular to the profile, until the inner bearing element engages positively with the outer bearing element. In this position, the mounting profile is secured against lifting from the base profile on the bearing side and can be lowered onto the base profile with the other side. With the mounting profile lowered onto the base profile, it is then moved laterally in the opposite direction, perpendicular to the profile, so that the inwardly directed positive locking element of the mounting profile engages with the outwardly directed positive locking element of the base profile. The locking element is then inserted into the recess, thus fixing the mounting profile transversely to the base profile. In the assembled state, the outer and inner bearing elements form a first bearing or...The connection point, and the outer and inner positive locking elements, form a second bearing or connection point. The maximum overlap of the bearing elements at the first connection point is greater than the maximum engagement path of the positive locking elements at the second connection point.

[0009] In cross-section, the base profile has its greatest width between its two ends, while the mounting profile has a mounting opening with a smallest width between its two side wall sections. The smallest opening width of the mounting profile is, in particular, smaller than the greatest width of the base profile. This design creates undercuts at the two bearing points when assembled, preventing the mounting profile from lifting off the base profile. Preferably, the bearing section of the mounting profile, viewed in cross-section through the profile, has a greater width than the width of the lateral displacement required to engage the outer positive locking element with the inner positive locking element.

[0010] In one embodiment, the inner and outer bearing elements can each be designed as longitudinal projections or webs that can be laterally slid into one another. The outer web engages in a longitudinal groove formed between the inner web and the base section. The outer positive-locking element of the base profile can be designed as a lateral longitudinal groove, and the inner positive-locking element as a longitudinal projection or web. However, a kinematic reversal is also possible, with the outer positive-locking element designed as a web and the inner positive-locking element as a groove. The positive engagement is achieved by laterally sliding the mounting profile relative to the base profile, i.e., transversely to the longitudinal extent of the profiles.

[0011] According to one embodiment, the base profile can have support surfaces on its upper side against which the mounting profile, with its corresponding contact surfaces, can rest during lowering. By supporting the mounting plate in a direction orthogonal to the base section, the mounting plate is held at such a distance from the base plate that the corresponding bearing elements or positive locking elements are aligned, enabling them to engage with each other through a simple transverse movement.

[0012] The base profile and / or the mounting profile are preferably made of a corrosion-resistant metal, in particular of anodized aluminium or an aluminium-containing alloy, although other materials are also possible in principle.

[0013] The described profile connection consisting of a base profile and a mounting profile can, in principle, be used or implemented at one or more points in the railing system.

[0014] In one possibility, the base profile is the top profile of a baluster system, and the mounting profile is a handrail of the baluster system. In this case, the top profile is understood to be the profile that is placed on the balusters and firmly connected to them by the fasteners. In this design, the locking element is preferably designed so that it can be inserted without tools, in particular by positive locking into the longitudinal recess. This design also allows the locking element to be easily removed for maintenance or repair work and then reinstalled. Specifically, the locking element, viewed in cross-section, can have an extended head section that is elastically shaped in the later direction, so that it can be clipped into the longitudinal recess with an undercut.The locking element can be designed, in particular, as an elongated locking profile, with, for example, two or more locking elements being used per meter along the railing system. The locking element can be made of a plastic, especially a polyamide.

[0015] In a second possibility, the base profile is a fastening profile, and the mounting profile is a baluster support profile of the baluster system. In this design, the fastening profile is understood to be the profile of the baluster system that is rigidly connected to a fixed component such as a base plate. The baluster support profile is the profile that carries the balusters. In this design, the locking element is preferably L-shaped and has an actuating section and a locking section. The locking element can be inserted into a space formed between the outer bearing element and the fixed component until the locking section is flush with the longitudinal recess. In this inserted state, the locking element can be rotated about a pivot axis so that the locking section is pivoted upwards and engages in the longitudinal recess. In this way, the baluster support profile is secured against lateral movement relative to the fastening profile.The locking section of the locking element, viewed in cross-section through the longitudinal recess, can have two lateral projections that engage with an undercut into the longitudinal recess. The actuating section can have engagement means at its free end for a tool to rotate the locking element. Preferably, in this embodiment, the locking element is made of a non-corrosive metal, in particular stainless steel. In a further embodiment, a locking element can be provided which, in the locked position of the locking element, can be slid onto it to secure the locking element against unwanted rotation. The locking element can be designed in the form of a clamp having two clamping arms with locking lugs. The clamping arms can grip the locking element laterally. When slid onto the locking element, the locking lugs engage positively in lateral recesses of the locking element.The locking element is preferably made of a plastic, in particular a polyamide.

[0017] The Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 to Fig. Figure 9, which are described together below, show a railing system 2 according to the invention, comprising a support profile arrangement 3 and a handrail profile arrangement 4. The railing system 2 is designed here as a bar railing system, but is not limited to this. The railing system can be used, for example, for safety on a balcony, a Juliet balcony, or a staircase.

[0018] According to the invention, at least one of the two profile arrangements, i.e., the support profile arrangement 3 and / or the handrail profile arrangement 4, comprises a base profile 6, 106, a mounting profile 7, 107, and a locking element 20, 120. The construction and assembly of the support profile arrangement 3 and the handrail profile arrangement 4 largely correspond to one another, so that the basic principle of the railing system 2 according to the invention and its assembly are explained below with reference to the handrail profile arrangement 4. For the purposes of this document, those details of the support profile arrangement 3 that correspond to those of the handrail profile arrangement 4 are designated with reference numerals raised by the number 100.

[0019] The base profile 6 comprises a base section 8 with several through-openings 9 for fasteners 10, a first side 11 with an outer bearing element 12, and a second side 13 with an outer positive-locking element 14. The outer bearing element 12 and the outer positive-locking element 14 are oriented in opposite lateral directions extending from the base section 8, transversely to the longitudinally extending base profile. Here, the longitudinal direction is designated L and the transverse direction generally Q, with specific directions designated Q1 and Q2.

[0020] The mounting profile 7, viewed in cross-section, is designed in the form of a cover or U-shape, so that it can be connected to the base profile 8 in a covering manner. Specifically, the mounting profile 7 has a first side wall section 15 with an inner bearing element 16, which can be brought into positive engagement with the outer bearing element 12 of the base profile 6 by being inserted laterally in direction Q1, and a second side wall section 17 with an inner positive locking element 18, which can be brought into engagement with the outer positive locking element 14 of the base profile 6 by laterally sliding the mounting profile 7 in the opposite direction Q2. When the positive locking elements 13 and 14 are engaged, a longitudinal recess 19 is formed between the base section 8 of the base profile 6 and the inner bearing element 16 of the mounting profile 7.To secure the mounting profile 7 against lateral movement in the transverse direction Q, a locking element 20 is inserted into the recess 19. In this way, the mounting profile 7 is fixed to the base profile 6.

[0021] In the present embodiment, the outer and inner bearing elements 12 and 16 are each designed as longitudinal projections or webs that can be slid laterally into one another. The outer bearing element 12 engages in a longitudinal groove 21 formed between the inner bearing element 16 and the base section 8. The outer positive locking element 14 of the base profile 6 is designed as a longitudinal groove in the second side 13, into which the inner positive locking element 18, designed as a projection, engages. In this way, a positive locking connection is established in the vertical direction H, so that the mounting profile 7, designed as a handrail, can no longer be lifted off the base profile 6. The longitudinal projection, which can also be referred to as a pin or longitudinal web, is preferably slightly conical inwards so that it can be easily inserted into the longitudinal groove of the base profile 6.

[0022] The base profile 6, viewed in cross-section, has a maximum profile width B6 between its two ends. The mounting profile 7 has a mounting opening 22 between its two side wall sections 15 and 17, with a minimum opening width B22 (compare Fig. 4C). It can be seen that the smallest opening width B22 of the mounting profile 7 is smaller than the largest profile width B6 of the base profile 6. This design creates undercuts at the two lateral bearing points when the profile is mounted, thus preventing the mounting profile from lifting off the base profile in the vertical direction H. Preferably, the bearing section 16 of the mounting profile 7 has a cross-sectional width B16 greater than the width of the lateral displacement path in order to engage the outer positive locking element 18 with the inner positive locking element 14.

[0023] In the present embodiment, the base profile 6 has a support surface 23 on its upper side, against which the mounting profile 7 can rest with a corresponding contact surface 25 when the first bearing point is threaded in or lowered. By supporting the mounting profile 7 in a direction orthogonal to the base section 8, it is held at such a distance from the base profile 6 that the corresponding bearing elements 12, 16 and the corresponding positive-locking elements 14, 18 are positioned so that they can engage with each other by a simple transverse movement. Optionally, an elastic element 26, for example in the form of a longitudinally extending rubber profile, can be arranged between the base profile 6 and the mounting profile 7. The elastic element 26 can, for example, be inserted in a longitudinal groove 24 on the upper side of the base profile 6, bearing against the mounting profile 7 under elastic preload.In this way, the two profiles are elastically supported against each other in the vertical direction H, so that unwanted rattling can be avoided.

[0024] In the handrail profile arrangement 4 described here, the locking element 20, which is included as a detail in the Fig. As shown in Figures 3A to 3C, the locking element 20 is preferably designed to be inserted without tools, in particular by positive locking and clipping into the longitudinal recess 19. This design allows the locking element 20 to be easily removed for maintenance or repair work and then reinstalled. In cross-section, the locking element 20 has a base section 27 and an extended head section 28 projecting from it. The head section 28 is elastically shaped in the transverse direction Q so that it can be clipped into the longitudinal recess 19 with an undercut. For this purpose, the head section 28 can be formed at the ends of two leg sections 29, 29', which are elastically resilient relative to each other in the transverse direction. The base section 27 has a width B27, which at least largely covers the opening formed between the first side 11 of the base profile 6 and the first side wall section 15 of the mounting profile 7.As especially in the . Fig. 3B and Fig. As can be seen in Figure 3C, the locking element 20 is designed in particular as an elongated locking profile, the length L20 of which is preferably more than twice as long as the width B27. For example, two or more locking elements 20 per meter can be used or clipped in along the railing system 2.

[0025] The locking element 20 can be made of a plastic, in particular a polyamide. The base profile 6 and / or the mounting profile 7 are preferably made of a corrosion-resistant metal, in particular anodized aluminum or an aluminum alloy, although other materials are also possible in principle.

[0026] The assembly of the handrail profile arrangement 4 is described below using the following: Fig. 4A to 4D explained in more detail.

[0027] As in Fig. As shown in Figure 4A, the mounting profile 7 is first placed at an angle onto the base profile 6 and then moved laterally so that the inner bearing element 16 engages positively with the outer bearing element 12, or the outer bearing element 12 engages in the longitudinal groove 21. For simplified lateral insertion of the mounting profile 7 into the base profile 6, the inner bearing element 16 can have a tapered section 42 at its inner upper end, allowing it to be easily slid under the outer bearing element 12 at an angle. The lateral movement is indicated by arrow P1. Fig. In the position shown in 4A, the mounting profile 7 is secured against lifting off the base profile 6 on the bearing side.

[0028] The next step, which involves Fig. As shown in Figure 4B, the mounting profile 7 can be lowered onto the base profile 6 with its other side. The pivoting movement around the first bearing point (12, 16) is indicated by arrow P2. In the pivoted or lowered state onto the base profile 6, the inner positive locking element 18 is aligned with the inner positive locking element 14. In the next step, the mounting profile 7 can be moved laterally in the transverse direction Q2. This movement is indicated by arrow P3. During the lateral movement, the inwardly directed positive locking element 18 of the mounting profile 7 engages with the outwardly directed positive locking element 14 of the base profile 6. This creates the longitudinal recess 19 on the side that was first engaged, between the outer bearing element 12 of the base profile 6 and the inner bearing element 16 of the mounting profile 7. This state is shown in Figure 4B. Fig. 4C is shown. The locking element 20 is then inserted into the recess 19, so that the mounting profile 7 is fixed relative to the base profile 6 in the transverse direction Q. The clipping movement is shown in Fig. 4D is represented by the arrow P4. The extended head section 28 engages on the inner side in a lateral undercut 43 of the base profile 6 and on the outer side in an undercut formed by the taper 42 of the inner bearing element 12. In the assembled state, the outer and inner bearing elements 12, 16 form a first bearing or connection point, and the outer and inner positive locking elements 14, 18 form a second bearing or connection point. The Fig. The arrangement shown in 4A to 4D is designed or depicted without the optional elastic element.

[0029] As mentioned above, the described profile arrangement consisting of base profile 6 and mounting profile 7 can, in principle, be used at various points within the railing system 2. The following section illustrates this. Fig. 5, Fig. 6, Fig. 7, Fig. 8 to Fig. 9 describes the support profile arrangement 3, which can be designed according to the invention as an alternative or supplement to the handrail profile arrangement 4. The construction and assembly of the support profile arrangement 3 largely corresponds to that described in the Fig. 2, Fig. 3 to Fig. Section 4 describes the handrail profile arrangement 4, so that reference is made to the description above to avoid repetition. Identical or corresponding details are indicated by numbers raised by 100.

[0030] In the support profile arrangement 3, the base profile 106 is a fastening profile, and the mounting profile 107 is a bar support profile of the bar railing system 2. The fastening profile is understood to be the profile of the bar railing system 2 that is firmly connected to a fixed component 30, such as a base plate. The bar support profile is the profile that carries the railing bars 5.

[0031] In the first step, the base profile 106 is fastened to the substrate with appropriate anchors or fasteners 110, for example with concrete screws in concrete. Fig. Figure 9A shows the state in which the base profile 106 is connected to the stationary component 30. The bar support profile with the pre-assembled railing bars 5 is then attached at a slight angle to the outside of the base profile 106 and slid to the left under the outer support element 112 of the base profile 106 using the inner bearing element 116 of the mounting profile 107. This causes the positive locking element 118, which projects inwards from the side wall 117, to extend beyond the base profile 106. Furthermore, the two interlocking bearing elements 112 and 116 form a bearing point around which the bar support profile can pivot. The bar support profile, or mounting profile 107, can then be lowered on the left side so that it is parallel to the base profile 106.Finally, the mounting profile 107 is pushed to the right so that the inwardly projecting positive locking element 118, which here is designed in the form of a tapered projection, slides or is pushed into the side of the base profile 106, which is designed accordingly as a groove, together with the outer positive locking element 114. This state is shown in . Fig. 9B shown.

[0032] In the next step, the profile arrangement 3 is secured by means of the locking element 120, with particular reference initially to the Fig. Sections 6A to 8B will discuss the design of the locking element 120 in more detail.

[0033] As especially in the Fig. 6C and Fig. As can be seen in Figure 6D, the locking element 120 is preferably L-shaped and comprises an actuating section 31 with a locking section 32 projecting at an angle from it. The locking element 120 can be inserted in a flat position into the space 33 formed between the outer bearing element 112 and the stationary component 30 until the locking section 32 is aligned with the longitudinal recess 119. In this inserted position, the locking element 120 can be rotated about its axis of rotation A, so that the locking section 32 is pivoted upwards and engages in the longitudinal recess 119.

[0034] The locking section 32 of the locking element 120, viewed in longitudinal section through the locking element, can have two lateral projections 34, 34' which can engage with an undercut into the longitudinal recess 119. The actuating section 31 can have engagement means 35 at its free end for a tool 41 to rotate the locking element 120 about its axis A. For example, the engagement means 35 can be designed in the form of an internal hexagon socket opening into which an external hexagon key can engage positively. It is understood that other tools or engagement means are also possible, such as slotted or Phillips head profiles. Fig. In Figure 9B, the locking element 120 is inserted flat into the recess 33, with the tool 41, here in the form of an external hexagon key, also shown, inserted into the engagement means 35. The locking element 120 can then be rotated 90° to the left using the tool 41. This is shown in Fig. 9C is represented by the arrow P5.

[0035] The corner area of ​​the locking section 32, located at the top in the direction of rotation from the flat to the up position, can have a flattened section 36 or a rounded edge to prevent collision with the outer bearing element 112 or to prevent it from rotating into the closed position. The locking section 32 of the locking element 120, now pointing upwards after being rotated 90° from the flat position, thus blocks the bar support profile and prevents unintentional disassembly of the entire module.

[0036] In a further optional embodiment, a locking element 37 can be provided which, in the closed position of the locking element 120, can be slid onto it to secure the locking element against unintentional rotation. The locking element 37, which is shown as a detail in the Fig.The clamp shown in Figures 7A to 7C is designed in the form of a clamp having two clamping arms 38, 38' with locking lugs 39, 39' at their ends. The clamping arms 38, 38' can laterally engage the locking element 120, with the locking lugs 39, 39' engaging positively in lateral recesses 40, 40' of the locking element 120 when slid into place. The clamp prevents the locking element 120 from unintentionally returning to its flat initial position. When clipped in, it can only be intentionally released by hand or with the aid of a suitable tool, such as needle-nose pliers.

[0037] Preferably, in this embodiment, the locking element 120 is made of a non-corrosive metal, in particular stainless steel. The locking element 37 is preferably made of a plastic, in particular a polyamide.

[0038] For each profile element or mounting profile 107, at least two locking elements 120 or securing elements 37 are preferably provided. In this way, the bar beam profile is secured against lateral movement relative to the fastening profile along its entire length.

[0039] For additional tensioning of the mounting profile 107 relative to the base profile 106 in the transverse direction Q, lateral clamping devices can optionally be provided, which generate a preload force between the side wall section 117 and the base profile 106. For this purpose, for example, at least two threaded studs (not shown) can be screwed through the side wall section 117 per module, the inner ends or screw tips of which can bear against a lateral upper end of the base profile 106 above the positive locking element 114. This creates a counter-pressure against the anti-levering device, so that the mounting profile 107 is clamped relative to the base profile 106 in both transverse directions.

[0040] As a further option, at least two boreholes per module can be drilled through the side wall section 115 on the mounting profile 107 or bar support profile from the outside, through which a filler, for example a two-component mortar, can subsequently be injected. After injection, the mortar hardens, thus permanently preventing the profiles from shifting.

[0041] Another special feature of the present embodiment is that the base profile 6 has two support surfaces 123, 123' on its upper side, against which the mounting profile 7 can be supported in the vertical direction H with corresponding contact surfaces 125, 125'. Optionally, compensating strips can be applied to the profile contact surfaces 125, 125', so that direct contact with the opposing surfaces 123, 123' is established.

[0042] Optionally, the mounting profile 107 can be prestressed in the vertical direction H against the base profile 106 using suitable prestressing devices (not shown). For this purpose, two threaded rods can be inserted from above through the handrail profile 6 and through the baluster itself to the base profile 106 in a subset of the balusters, particularly on the outermost right and left balusters of each module. The threaded rods can be screwed through a threaded hole in the mounting profile 107 and supported at their lower end against an upper support surface of the base profile 106. By screwing in the threaded rod, the mounting profile 107 is prestressed against the base profile 106 in the vertical direction, so that this connection is free of play.At the upper end, the threaded rods can pass through openings in the handrail profile 6, so that torque can be introduced into the threaded rods from above on the pre-assembled module in order to screw the mounting profile 107 to the base profile 106 at the lower end.

[0043] Overall, the railing system 2 according to the invention enables the two profiles of the railing system to be easily connected to each other by means of a surface-mounted assembly and insertion, whereby two-sided bearing points can be realized without visible screws. The locking element 20, 120 or anti-lever device required for this purpose serves to secure the mounting profile 7, 107 against unintentional or intentional prying out of the base profile 6, 106.
