Abstract

The present invention relates to a fence system (2) with a number of welded wire mesh panels (4) which are attached to posts (6) erected between the welded wire mesh panels (4). The posts (6) consist of first angle profiles (12) which have insertion slots (28) into which the transverse wires (8) of a welded wire mesh panel (4) are inserted, and then a fixing element (22), which also has insertion slots (28), is placed onto the transverse wires (8). The fence system (2) is therefore limited to welded wire mesh panels (4), first angle profiles (12) and fixing elements (22) which are connected to each other without tools via the suitably shaped insertion slots (28).

Description

[0001] The present invention relates to a fence system comprising a number of welded wire mesh panels which are attached to posts erected between the welded wire mesh panels.

[0002] A fence system is known from German patent application DE 20 2009 016 369 U1. Such fence systems are used in particular as protective devices for machines and / or equipment. It is mandatory to cover and protect the moving parts of machines and / or equipment in such a way that people are not exposed to any danger. Corresponding regulations are contained, for example, in standards EN 12100, EN 294, EN 811, EN 953, and EN 1088, as well as in the Machinery Directive. The size of the fence systems, i.e., the height and width of the individual elements such as posts and protective grilles, as well as their distance from the danger zone, depends on the machines and / or equipment and the potential hazard they pose. This, in turn, influences the thickness of the protective grilles and the dimensions of the posts. For example, parts that might fly off the machine and / or equipment must be caught by such a protective device with welded wire mesh panels and posts.

[0003] Welded wire mesh panels are available as purchased components in a variety of square or rectangular grid sizes, for example, 20, 30, 40, or 50 mm, and in various wire thicknesses from 2 to 8 mm. They must be securely attached to the posts. The welded wire mesh panels described in German patent DE 20 2009 016 369 U1 are held in a frame that encompasses the panel and is, in turn, attached to the adjacent posts. The frames and posts are connected by fittings that must be attached to the frame and posts during fence assembly. Screwing the frames to the posts is very time-consuming. The welded wire mesh panels must also have been pre-installed in their respective frames or welded to them. Overall, this makes the manufacturing and assembly of the fence system very complex.The complex installation also prevents easy and quick access to the area enclosed by the fence in the event of repairs and maintenance work.

[0004] The object of the present invention is to simplify the manufacture and assembly of a fence system.

[0005] The problem is solved for a fence system of the generic type by the features of claim 1.

[0006] The fence system has a number of posts from which the welded wire mesh panels are suspended. The posts are elongated, vertically installed load-bearing elements within buildings and supported in the ground.

[0007] At least one fence post has a first angle profile with at least two legs. This first angle profile can be bent or rolled from sheet metal. The material thickness and type depend on the intended use. The first angle profile can have an L- or U-shaped cross-section.

[0008] At least one of the legs of the first angle profile has openings on its free outer edge containing a number of insertion slots that extend inwards from the free outer edge. Each insertion slot forms a channel into which transverse wires of a welded wire mesh panel can be inserted. The inward extension means that the insertion slots extend over a portion of the width of the leg in which they are located. The insertion slots are closed at their ends opposite the opening. The end of an insertion slot acts as a stop for a wire inserted into it. Therefore, a welded wire mesh panel, with its transverse wires inserted into the slots, can only be inserted as far as the slot allows.The insertion slot can be straight, simply curved, or multiply curved. If the slot slopes downwards, at least partially, from the opening, the transverse wires, after passing through the opening, are automatically drawn deeper into the slot by the weight of the welded wire mesh panel. This facilitates installation on-site. Furthermore, if the welded wire mesh panel is struck from the side, it will not simply slip out of the insertion slot unless it is also lifted. The insertion slots can also have a labyrinthine design, which further prevents the transverse wires from unintentionally slipping out.

[0009] When this description refers to a welded wire mesh panel, this term is not limited to welded wire mesh panels in the strict technical sense. The term also covers designs of flat elements that have projections on their lateral edges, which, like the transverse wires of a welded wire mesh panel, can be inserted into the slots of the first angle profile. In this respect, the term "welded wire mesh panel" is also synonymous with, for example, closed sheet metal panels, plexiglass sheets, or even boxes with correspondingly shaped projections on the sides, which can be installed in a fence system via these projections, similar to a welded wire mesh panel.

[0010] The insertion slots in the first angle profile are parallel to each other and each has a channel width that corresponds at least to the wire diameter of the transverse wires of a welded wire mesh panel, by which the panel is inserted into the slots in the first angle profile. The width of an insertion slot can remain constant or vary along its length. The insertion slots can also be so wide that the leg of the first angle profile containing the insertion slots has a comb-like design, with only narrow teeth protruding between the slots. The parallel orientation of the insertion slots also allows the transverse wires of a welded wire mesh panel to be inserted into the openings of the insertion slots with a single insertion motion and then further lowered into the slots without individual wires becoming jammed.

[0011] Advantageously, the spacing and number of insertion slots correspond to the spacing and number of transverse wires of the welded wire mesh panel in the area of ​​the angle profile. Otherwise, individual wires extending to the first angle profile, for which there is no suitable insertion slot in the first angle profile, would block the insertion process. However, a welded wire mesh panel does not necessarily have to extend over the entire height of the first angle profile. The panel can be shorter than the first angle profile to which it is attached. It is also possible to attach several welded wire mesh panels to two angle profiles that are separated by height.

[0012] For welded wire mesh panels with different mesh spacings, different first angle profiles with correspondingly differently arranged and dimensioned insertion slots are required. These can be kept readily available as part of a modular system to meet various technical requirements. For example, first angle profiles with 30 mm spacing and insertion slots spaced 30 mm apart can be provided for welded wire mesh panels with a 40 mm spacing, and so on.

[0013] In the area of ​​the leg of the first angle profile equipped with the insertion slots, at least one fixing element with a number of insertion slots is placed onto the transverse wires of the welded wire mesh panel suspended in the first angle profile. The above descriptions of the insertion slots in the first angle profile apply accordingly to the design of the insertion slots in the fixing element. The purpose of the fixing element is to secure the transverse wires of a welded wire mesh panel in the respective insertion slots. Since the insertion slots in the leg of the first angle profile are open in the direction of the corresponding openings, a welded wire mesh panel could fall out of the insertion slots if struck, without an attached fixing element. To prevent this, the fixing element is used to secure the transverse wires of the welded wire mesh panel in the insertion slots of the first angle profile.The fixing element has a shape suitable for its function and can, for example, be designed as a flat sheet metal strip or as the leg of a second angle profile, whereby such an angle profile can then, for example, have an L- or U-shaped cross-sectional shape.

[0014] To allow a fixing element to be slid onto the transverse wires of a welded wire mesh panel suspended in the first angle profile, the openings of the insertion slots formed in the fixing element are located on the outer edge pointing in the direction of the insertion slots in the leg of the first angle profile. This arrangement of the openings and the orientation of the insertion slots in the fixing element allows the fixing element to be moved towards the first angle profile from the same direction as the welded wire mesh panel during installation. Within the area of ​​the insertion slots, the fixing element can then be slid over the transverse wires of the welded wire mesh panel held in the first angle profile and pushed through the welded wire mesh panel.

[0015] The insertion slots in the fixing element form channels through which the fixing element can be slid over the transversely extending wires of a wire mesh panel suspended in the first angle profile. The inward extension direction means that the insertion slots in the fixing element extend over a portion of the fixing element's width. The insertion slots in the fixing element are closed at their ends opposite the opening. The ends of the insertion slots in the fixing element form a stop for the fixing element, which has been slid over the transversely extending wires of a wire mesh panel suspended in the first angle profile.The insertion slots formed in the fixing element can have an arrangement or course along their length that blocks or hinders a pull-off movement of the fixing element, at least in a horizontal direction. In this way, the transverse wires inserted into the insertion slots in the first angle profile are also fixed in their installed position and secured against falling out in the event of an impact.

[0016] The insertion slots in the fixing element extend inwards from the outer edge in a direction opposite to the insertion slots in the first angle profile. This orientation of the insertion slots makes it possible to position the fixing element with its formed openings against the transverse wires and then move the fixing element further towards the welded wire mesh and the first angle profile, so that the transverse wires of the narrowed welded wire mesh insert into the insertion slots in the fixing element and the fixing element partially penetrates the welded wire mesh.

[0017] The insertion slots in the fixing element are parallel to each other and each has a channel width that corresponds at least to the wire diameter of the transverse wires of the welded wire mesh panel that is inserted into the slots in the first angle profile. The width of an insertion slot in the fixing element can remain constant or vary along its length. Due to the parallel orientation of the insertion slots, the fixing element can be slid over the transverse wires of a welded wire mesh panel inserted into the first angle profile and pushed through the mesh of the panel. To do this, the fixing element is positioned with the openings of the insertion slots against the transverse wires and then pushed further towards them, so that the transverse wires are lowered deeper into the insertion slots without any individual wires becoming jammed.Advantageously, the spacing and number of insertion slots correspond to the spacing and number of transverse wires of the welded wire mesh panel suspended in the first angle profile. Otherwise, individual wires extending to the fixing element, for which there is no suitable insertion slot in the fixing element, would block the sliding motion. Therefore, different fixing elements with correspondingly differently arranged and dimensioned insertion slots are required for welded wire mesh panels with different grid dimensions. These can be kept readily available as part of a modular system to meet various technical requirements.

[0018] For the fixing element to function correctly, it is not necessary for it to extend to the same height as the first angle profile and / or the welded wire mesh panel. In particular, the fixing element can be shorter than the first angle profile and / or the welded wire mesh panel. The fixing element also does not necessarily have to be a single piece extending the full height of the first angle profile and / or the welded wire mesh panel. For easier installation, several short fixing elements can be attached to a long first angle profile post, distributed across the height of the first angle profile and / or the welded wire mesh panel.

[0019] The first angle profiles and fixing elements can be bent or rolled from metal sheets. The insertion slots in the first angle profiles and fixing elements can be punched or laser-cut from the sheets.

[0020] Only one side end of a single welded wire mesh panel can be attached to the leg of the first angle profile, meaning that two first angle profiles and two fixing elements are used for each welded wire mesh panel in the fence system. However, the side ends of two consecutive welded wire mesh panels in the fence system can also be attached to the leg of a first angle profile, and the two welded wire mesh panels attached to the first angle profile can be secured with a fixing element in the area of ​​this first angle profile. With this type of installation, only one first angle profile and one fixing element are required per welded wire mesh panel; the last first angle profile and the last fixing element of the chain in a fence system are not included in this count.Finally, it is possible, in the case of a fence system and a first angle profile with a U-shaped cross-section, to hang a first lateral end of a welded wire mesh panel into each free leg of the first angle profile and to secure it with a fixing element.

[0021] The welded wire mesh panels can be hung directly and without tools in the first angle profiles of the posts, without an additional frame, before the fixing elements are then attached to the panels. No connecting parts such as brackets, angles, screws, etc., are required. This significantly reduces manufacturing and assembly costs, and the amount of material needed for the fence is also lower compared to conventional fencing systems. As a result, the fence is considerably more cost-effective to produce.

[0022] The first angle profiles and fixing elements, which may also be designed as second angle profiles, as well as the associated welded wire mesh panels, can be kept in a modular system in various material thicknesses, dimensions, divisions and wire thicknesses, which makes it possible to create fence systems in almost any size to suit almost any protection requirements.

[0023] For the stability of the fence system constructed in this way, it is important that the numerous individual transverse wires of a welded wire mesh panel, by which the panel is suspended from a first angle profile, create a corresponding number of connection points between the panel and a post. The welded wire mesh panel is no longer connected to the post, for example, only at the top and bottom with individual tabs, but rather a welded wire mesh panel with a 40 mm grid spacing has 50 transverse wires along its 2 m height, which can be inserted into a corresponding number of slots. These 50 transverse wires alone provide considerable holding power.By additionally securing the transverse wires inserted into the slots in the first angle profile with the fixing element, even higher loads acting on the welded wire mesh panel can be transferred and dissipated to the post via the comparatively high number of connections and the fixing element, without the welded wire mesh panel being forced out of its installed position. The proposed connection technique, which eliminates the need for a frame surrounding the welded wire mesh panel, does not compromise the security of the fence system.

[0024] The process of mounting a welded wire mesh panel to two posts equipped with the proposed fastening system is remarkably simple: two angle brackets are fixed to the ground at the desired distance from each other at the fence installation site. The welded wire mesh panel is then inserted into the slots in the angle brackets, with the transverse wires at its side ends. Finally, the fixing element, with its corresponding slots, is simply slipped over the transverse wires of the welded wire mesh panel to complete the installation. Removing the welded wire mesh panel for maintenance or repair work on the fenced-in machinery is easily accomplished by simply reversing the above procedure. Replacing a damaged welded wire mesh panel is also easily accomplished in this way.

[0025] The grid pattern of the welded wire mesh panels allows for length and angle adjustment between the panel and a post. Angle adjustment with a non-linear arrangement of posts and panels is possible if the insertion slots and transverse wires in their connection area have sufficient degrees of freedom relative to each other, allowing the transverse wires to be positioned at an angle to the connection point, thus acting as a hinge. This allows a fence to have a non-linear course in sections. When a welded wire mesh panel is inserted into the first angle profile, the two vertical wires closest to the insertion slot act as stops, allowing the panel to be slid back and forth along the length of the fence.With a 40 mm grid spacing for a welded wire mesh panel, the panel can be shifted up to 40 mm from one stop to the other. Furthermore, it is possible to attach a welded wire mesh panel not only to its outermost grid in the lateral direction, but also to any of the subsequent grids in the first angle profile. Therefore, a post does not need to be positioned with millimeter precision; the fence system has tolerances along its length across the grid sections, allowing minor inaccuracies in post positioning to be compensated for by length adjustment.

[0026] The first angle profile and the fixing element together form a post of the fence system. The fixing element can be designed so that it can also be connected to the ground, for example, by a base plate. The fixing element can also be connected to the first angle profile if necessary, for example, using clamps, screws, or other fasteners. The first angle profile and the fixing element are positioned directly adjacent to each other.

[0027] The fixing element is one leg of a second angle profile. Designing the fixing element as a second angle profile with at least one additional leg stiffens it against potential torsional and bending movements. This makes the fence system significantly more stable. In the installed position, one leg of the second angle profile can cover the connection area between the suspended welded wire mesh panel and the first angle profile, which is more aesthetically pleasing. Furthermore, the fixing element, designed as a second angle profile, is easier to handle because it is easier to grip and less prone to flexing during installation.

[0028] The first and / or second angle profile is designed as a U-profile, and the two legs extending from the base of the U-profile(s) have openings at their free outer edges for insertion slots into which the transverse wires of a welded wire mesh panel suspended from the first angle profile are inserted. Due to the double bending, the U-profiles are very rigid and can bear high loads. Within a U-profile, the respective legs can be bent at right angles to each other. The U-profiles can together form a post. One of the two U-profiles can have a slightly wider base than the other, so that the two lateral legs of this U-profile encompass the two lateral legs of the other U-profile. The U-profiles can then support each other.The two free legs of a U-profile can also be used to hang an end of a welded wire mesh panel on each leg, which theoretically allows for an endless linking of welded wire mesh panels with posts arranged in between to form a fence system, with each welded wire mesh panel then being held by one leg of a U-profile.

[0029] According to one embodiment of the invention, the welded wire mesh panel is bent at least once in its upper and / or lower region. This bending increases the inherent stiffness of the welded wire mesh panel. The panel can also be bent multiple times, for example, to form a cable duct at the upper or lower end. The load-bearing capacity of the bent welded wire mesh panels can be increased, if required, by sheet metal profiles that are connected to the panel in the bending area. The sheet metal profiles can simply be inserted into a bent recess, or they can additionally be screwed or welded to the welded wire mesh panel.

[0030] According to one embodiment of the invention, the insertion slots formed in the first angle profile extend, at least partially, down into a plane below the respective opening from the direction of the openings, and the insertion slots formed in the fixing element extend, at least partially, up into a plane above the respective opening from the direction of the openings.

[0031] According to one embodiment of the invention, the first angle profiles used have a base plate for fixing them to the ground. The base plate can be provided with several extensions, each having one or more recesses for passing ground anchors. The recesses can have circumferential contours that define holes of different sizes, in order to allow ground anchors of varying thicknesses to pass through a correspondingly suitable hole in the recess. In addition to the first angle profile, the base plate can be connected to a fixing element via suitable connecting elements, which, for example, enable a non-destructively detachable connection by means of a snap-fit ​​or screw connection, or by welding.

[0032] According to one embodiment of the invention, at least one clamping bracket for connection to an attachment is mounted on at least one of the posts. Clamping brackets can be used, for example, to attach hinges or a lock case for a door to a post. Depending on the application, the number and design of the clamping brackets can be appropriately tailored and dimensioned.

[0033] According to one embodiment of the invention, at least one mounting bracket is attached to at least one of the posts by means of a plug-in tab inserted into a slot. One or more slots can be easily punched or laser-cut from the material of the first angle profile or the fixing element. This creates a fastening option that allows mounting brackets to be attached to a post without tools. The plug-in tabs formed on a mounting bracket have a suitable shape and dimensions that ensure simple and secure attachment of the mounting bracket to the post. The mounting brackets can be used, for example, to attach cable ducts, lamps, control cabinets, fuse boxes, and the like to the fence system.

[0034] According to one embodiment of the invention, at least one leg of the first angle profile and / or the fixing element is installed in the fence system at an angle relative to the vertical. The first angle profile and the fixing element can be installed vertically in the fence system. However, due to the leg being angled like a strut, higher forces can be absorbed and transferred into the ground in the event of an impact by a vehicle, person, or object against the welded wire mesh panel.From a side view, the first angle profile and / or the fixing element has a general triangular shape, whereby the legs of this triangular shape can be aligned along or parallel to the base profile and to the orientation of the usually vertically oriented wire mesh mat, and the leg, which is aligned with its transverse axis parallel to the longitudinal orientation of the wire mesh mat, forms the hypotenuse by virtue of its oblique position.

[0035] According to one embodiment of the invention, at least one first angle profile and an associated fixing element are connected to a welded wire mesh panel at a point between its lateral ends. This mounting position can be implemented either only at this point or in addition to first angle profiles and fixing elements connected to the welded wire mesh panel at its ends. The first angle profiles and / or the fixing elements used can be anchored to the ground or simply suspended from the welded wire mesh panel. They can effectively reinforce and stiffen a welded wire mesh panel in its installed position, for example, because a recess in the welded wire mesh panel, such as a door opening for an access door or a service hatch, weakens it. The posts then serve as a frame and / or stop for fixtures.

[0036] The first angle profiles and fixing elements positioned between the lateral ends of a welded wire mesh panel—just like those positioned at the lateral ends—do not need to extend exactly over the entire height of the panel, but can also be shorter or longer. Upright posts can be connected to each other by appropriately designed cross profiles for stiffening purposes or simply for aesthetic reasons.

[0037] An additional first angle profile with a fixing element can be useful, for example, if the welded wire mesh panel has a bend to form a corner in the fence system, and a post needs to be placed in precisely this corner for structural or aesthetic reasons. If one or more first angle profiles and associated fixing elements are connected to the welded wire mesh panel at any point between the side ends, this can also serve to attach control boxes, electrical distribution panels, or infill materials other than the welded wire mesh panel itself, such as sheet metal panels, polycarbonate sheets, and the like. When installing control boxes or electrical distribution panels on the welded wire mesh panels, the cavities in the first angle profiles, fixing elements, and the folded edges of the welded wire mesh panels can be effectively used for cable routing and installation.The first angle profiles and fixing elements mounted between the side ends of a welded wire mesh panel can be installed during the initial construction of a fence system, but it is also possible to install them later in a fence system.

[0038] According to one embodiment of the invention, a cable channel is formed on a wire mesh panel, which is composed of at least one first angle profile and at least one fixing element. The at least one first angle profile can be bent or rolled from a metal sheet, or cast or extruded as a plastic molded part. The material thickness, shape, and selected material depend on the specific application. For example, the first angle profile can be a profile with an L- or U-shaped cross-section. The insertion slots in the first angle profile can be punched or laser-cut from the sheet metal.

[0039] The first angle profile and the first fixing element are attached to opposite sides of the welded wire mesh panel. By positioning these components on opposite sides of the panel, they can be counter-locked and permanently fixed to the panel. To create a cable duct of a desired length, several first angle profiles can be used. It is also possible to use multiple fixing elements for one or more first angle profiles.

[0040] The first angle profile has at least two spaced-apart legs that define a receiving space for cables. The surfaces of the two legs shield the receiving space both inwards and outwards. The receiving space is designed to accommodate the cables. The two legs are connected by a base that shields the receiving space defined by the first angle profile from another side. After the first angle profile is attached to a wire mesh panel, the receiving space is bounded by the wire mesh panel on the side where the first angle profile is placed with its open cross-section. In this way, the receiving space is bounded and protected in a direction perpendicular to the direction of the cables laid in the cable duct.

[0041] The cross-sectional area of ​​the first angle profile is designed to provide a sufficiently large free cross-sectional area to accommodate the cables to be laid within it. For example, in the case of a U-shaped angle profile, the width of the legs supporting the first angle profile on the wire mesh panel determines the internal height of the receiving space, while the width of the base determines the width of the receiving space. Depending on the dimensions of the leg and base widths, different sized receiving spaces can be created. It is possible to keep various first angle profiles on hand, similar to a modular system, to allow for the use of cable ducts of different sizes as needed.Angle profiles with a small free cross-section of the receiving space can be used when only a single cable with a small cross-sectional area is to be laid in the cable duct, for example, to connect a switch, push button, light barrier, display, or camera—accessible from the outside of the fence or mounted outside the fence—to a machine control system. However, an angle profile with a comparatively large free cross-section of the receiving space can also be used to route many individual cables or one or more cables with a comparatively large cross-section along the fence.

[0042] At least one of the legs of the first angle profile has openings on a free outer edge, each containing a number of insertion slots that extend inwards from the free outer edge of the leg. Each insertion slot forms a channel through which the angle profile can be slid onto a transverse bar of the welded wire mesh panel. The inward extension means that the insertion slots extend over a portion of the width of the leg in which they are located. The insertion slots are closed at their ends opposite the opening. The end of each insertion slot acts as a stop for the bar onto which the angle profile with the insertion slot is slid.An angle profile, which is slid onto the transverse bars of the welded wire mesh panel using its insertion slots, can only be pushed onto the panel as far as the slots extend. The insertion slots can be straight, simply curved, or multiply curved. If the insertion slots are directed upwards, at least partially, from the openings, the angle profile's legs, after passing the transverse bars, slide automatically or with assistance along the slots into the spaces between the bars and through the plane of the welded wire mesh panel. This particularly simplifies the installation of the cable ducts on the construction site.If the angle profile is struck from the side, it will not simply slide out of its mounting position along the insertion slots, provided the angle profile is not also lifted. The insertion slots can also have a labyrinthine design, which further prevents the angle profile from unintentionally slipping out of the transverse bars.

[0043] The insertion slots in at least one first angle profile are parallel to each other and each has a channel width that corresponds at least to the thickness of transverse bars of the welded wire mesh panel. The width of an insertion slot can remain constant or vary along its length. The insertion slots formed in the first angle profile can have an arrangement or orientation along their length that prevents or hinders the angle profile from being pulled out, at least in a horizontal direction. In this way, the angle profile is at least partially secured against falling out upon impact. The insertion slots can also be so wide that the leg of the first angle profile with the insertion slots has a comb-like design, in which only narrow teeth protrude between the insertion slots.The parallel arrangement of the insertion slots also allows the legs of the angle profile with the openings and insertion slots to be pushed onto the transverse bars of the wire mesh mat with an insertion movement and then further lowered into the wire mesh mat without the legs becoming jammed with individual bars.

[0044] The spacing and number of insertion slots can correspond to the spacing and number of transverse bars of the welded wire mesh panel in the area of ​​the angle profile. Otherwise, individual bars extending to the first angle profile, for which there is no suitable insertion slot in the first angle profile, would block the insertion movement. The legs can also be made of different widths, so that where no insertion slots are formed, the legs end at the same point where the insertion slots would end in wider sections. The legs can then be designed, for example, to have projecting tabs at intervals of 25 cm or 50 cm, in which the insertion slots are formed, while the remaining free outer edges of a leg only rest on the surface of a welded wire mesh panel or even maintain a slight distance from it.

[0045] An angle profile does not necessarily have to extend over the entire height of the welded wire mesh panel. It is advantageous for the angle profile to be only as long as the cable duct is required on the welded wire mesh panel. The angle profile can then be cut to the appropriate length. It is also possible for the welded wire mesh panel to be less high than the angle profile, so that the cable duct extends beyond the panel, for example, to run the cable duct to the ceiling of a hall. It is also possible to run a single long angle profile along several welded wire mesh panels and hook it into them.

[0046] Since welded wire mesh panels are typically composed of bars arranged at right angles to each other, it is particularly easy to create cable ducts on welded wire mesh panels using an angle profile, whether the cable runs vertically or horizontally. An angle profile can be attached to a welded wire mesh panel not only vertically but also horizontally using its insertion slots. Because diagonal cable duct runs are often undesirable or even prohibited, this is not a significant disadvantage. With appropriate connectors or angle pieces, it is possible to attach diagonally running cable ducts to a welded wire mesh panel using an angle profile, or to create a cable duct with a stepped design that, in total, also runs diagonally across a welded wire mesh panel.

[0047] For welded wire mesh panels with different mesh spacings, different first angle profiles with correspondingly differently arranged and dimensioned insertion slots are required. These can be kept readily available as part of a modular system to meet various technical requirements. For example, first angle profiles with 30 mm spacing and insertion slots spaced 30 mm apart can be provided for welded wire mesh panels with a 40 mm spacing, and so on.The first angle profiles and fixing elements, which may also be designed as second angle profiles, as well as the associated welded wire mesh panels, can be kept in a modular system in various material thicknesses, dimensions, divisions and bar thicknesses, which makes it possible to create cable ducts on welded wire mesh panels in almost any size to suit almost any protection requirements.

[0048] At least one angle profile is hung in the welded wire mesh in the assembly position in such a way that transverse bars of the welded wire mesh run transversely through insertion slots in the angle profile.

[0049] The fixing element is connected to the at least one first angle profile via at least one connecting element. The at least one first angle profile, located on opposite sides of the welded wire mesh panel, and the at least one fixing element are connected to each other in their installed position via the connecting element(s). If the fixing element is larger than the grid dimension of the welded wire mesh panel, it cannot slip through a grid of the panel when connected to the first angle profile. In this way, the fixing element counteracts the first angle profile. For the fixing function of the fixing element, it is not necessary that it extends over the same height as the first angle profile and / or the welded wire mesh panel. In particular, the fixing element can be shorter than the first angle profile and / or the welded wire mesh panel.The fixing element does not necessarily have to be a single piece extending the full height of the first angle profile and / or the welded wire mesh panel. For easier installation, several short fixing elements can be attached to a long first angle profile and distributed across its height and / or the welded wire mesh panel.

[0050] The connecting elements do not have to be separate components, but can also be an integral part of the first angle profile and / or the fixing element. For example, the first angle profile and / or the fixing element can have corresponding and appropriately positioned hooks and hook receptacles that allow the fixing element to be hooked onto the first angle profile. Alternatively, the connecting elements can be designed as separate components, such as push or pull screws, that connect the first angle profile and the fixing element. These screws pull the angle profile and the fixing element towards each other and towards the wire mesh panel, or push them away from each other, so that the contours of the insertion slots interlock with the bars of the wire mesh panel.Instead of push or pull screws, eccentric clamping levers can also be used, which can be inserted into suitable openings and tightened without tools. When connected to a fixing element located on the other side of the welded wire mesh panel, at least the first angle profile can no longer be lifted off the panel without damage. The fixing element can also be designed so that it rests laterally against at least one leg of the first angle profile. If the leg is screwed to the fixing element in a direction parallel to the plane of the welded wire mesh panel, the first angle profile is also fixed in its installed position. The fixing element can be designed as a flat plate, an L- or U-shaped profile, or as any other three-dimensional body that is too large to fit through an open grid of the welded wire mesh panel. The material for the fixing element can be, for example, metal or plastic.

[0051] The installation of the cable duct according to the invention is considerably simplified. In particular, it is possible, as a first step, to attach the cables to be protected by the cable duct directly to the wire mesh panel at the point where the cable duct will later run. The cable(s) can be attached to the wire mesh panel quickly and easily, for example, using cable ties. With such an open installation of the cables, they are very accessible and can therefore be easily positioned and secured. If care has been taken during the installation of the cable(s) to ensure that they are located precisely where the cable duct will later be positioned, it is possible to place at least one angle profile onto the already installed cables in such a way that they are concealed by the first angle profile and are located within the receiving space formed in the first angle profile.If, during the insertion movement, the first angle profile is placed onto the wire mesh panel in such a way that the openings of the insertion slots are precisely aligned with the transverse bars of the wire mesh panel, it is possible to push the legs of the first angle profile further through the grid openings between the transverse bars of the wire mesh panel, so that the transverse bars of the wire mesh panel are positioned in the insertion slots. As soon as the legs of the first angle profile have penetrated the grid openings between the bars in the wire mesh panel, the receiving space in the first angle profile is completely closed, thus creating a closed cable duct.To complete the assembly, it is only necessary to fix the first angle profile in its installation position by connecting the fixing element to the first angle profile from the opposite side of the wire mesh mat using the connecting elements.

[0052] The first angle profile designed according to the invention makes it considerably easier to mount a cable duct on a wire mesh panel. If the cable duct is to be dismantled later, or if further cables are to be installed or removed from the cable duct, the cable duct can also be easily removed from the wire mesh panel by reversing the work sequence.

[0053] When this description refers to a welded wire mesh panel, the term is not limited to welded wire mesh panels in the strict technical sense. The term also covers designs of flat elements that have a structure similar to the transverse bars of a welded wire mesh panel, allowing for the attachment of an angle profile with its integrated slots. In this respect, the term "welded wire mesh panel" is also synonymous with, for example, sheet metal panels, plexiglass sheets, or boxes with correspondingly designed protrusions that enable the attachment of an angle profile by sliding the legs of the angle profile with the slots onto transverse elements, similar to a welded wire mesh panel in a fence system.

[0054] According to one embodiment of the invention, the first angle profile is designed as a profile with a U-shaped cross-section, in which the legs project at a right angle to the base. In this embodiment, the first angle profile is connected to the wire mesh panel via both legs and is thereby securely held in its mounting position. The angle profile can be manufactured cost-effectively. The receiving area has a rectangular cross-section, so that it can easily be placed like a cover onto a cable bundle laid on a wire mesh panel.

[0055] According to one embodiment of the invention, the legs of the first angle profile have separate recesses. These recesses can be used to guide cables out of or into the cable duct. The recesses can be located at regular intervals along the legs. The presence of recesses in the legs does not significantly increase the risk of damage to the cables within the cable duct because the legs are difficult to access from the side, thus reducing the risk of foreign objects striking the profile or liquids or sparks entering the cable duct through the recesses. With recesses in the side legs, the base of the angle profile can remain closed, ensuring that the protective function of the angle profile is fully maintained on this surface.

[0056] According to one embodiment of the invention, the insertion slots are sized such that, even when a transverse bar of the wire mesh panel is inserted into the respective slot, there is still room for a cable to pass through. If the insertion slots are dimensioned so that, even when the angle profile with the insertion slots is hooked into a wire mesh panel, a cable can still be guided through the insertion slot from the outside into the receiving space or from the receiving space to the outside, it is possible to dispense with separate openings for cable passages. The cables can then be easily guided into and out of the cable channel at points predetermined by the spacing of the insertion slots.

[0057] According to one embodiment of the invention, the first angle profile is made of a metallic material. The metallic material is well-suited to dissipating heat generated in the cables. This prevents higher cable temperatures and the resulting higher resistance and correspondingly higher power consumption. The metallic material also shields the cables against potential electromagnetic interference. Furthermore, the emission of high-frequency interference energy is reduced by a metallic angle profile.

[0058] According to one embodiment of the invention, in a vertical mounting position of the first angle profile on a welded wire mesh panel, the insertion slots extend upwards from the openings. The vertical mounting position of the first angle profile refers to a position in which the longitudinal center axis of the angle profile is at least approximately vertical. When, in this orientation, the insertion slots extend upwards from the opening, the angle profile, during installation, slides downwards along the transverse bars of the welded wire mesh panel, following the path of the insertion slots. The insertion movement of the first angle profile into the welded wire mesh panel is facilitated by its own weight, and the insertion slots guide the profile during this movement.Due to its own weight, an angle profile can only be removed from its installed position if it is lifted out following the angle of the insertion slots. The angled shape of the insertion slots thus provides a self-locking mechanism for the first angle profile in its installed position.

[0059] According to one embodiment of the invention, the fixing element is designed as a second angle profile with at least two spaced-apart legs, at least one of which has a number of openings on a free outer edge from which insertion slots extend inwards. The insertion slots in the second angle profile are parallel to each other and each has a channel width that corresponds at least to the thickness of the transverse bars of the welded wire mesh panel. A fixing element designed in this way can be mounted on a welded wire mesh panel in the same manner as described above for a first angle profile.To allow a fixing element to be slid onto the transverse bars of a welded wire mesh panel suspended in the first angle profile, the openings of the insertion slots formed in the fixing element are located on the outer edge, pointing in the same direction as the insertion slots in the leg of the first angle profile. This arrangement of the openings and the orientation of the insertion slots in the fixing element allows the fixing element to be moved towards the first angle profile during assembly and slid over the transverse bars of the welded wire mesh panel in the area of ​​the insertion slots. At least one leg of the first angle profile is also slid onto these bars. The insertion slots in the fixing element extend inwards from the outer edge of one leg in a direction opposite to that of the insertion slots in the first angle profile.This arrangement of the insertion slots allows the fixing element, with its integrated openings, to be positioned against the transverse bars. The fixing element can then be moved further towards the welded wire mesh panel and the first angle profile, so that the transverse bars of the welded wire mesh panel are inserted into the slots in the fixing element, and the fixing element partially penetrates the welded wire mesh panel. The design options described above for a first angle profile apply accordingly to the second angle profile sheet.

[0060] According to one embodiment of the invention, the fixing element is designed as a profile with a U-shaped cross-section, and the legs of the profile have a width such that, in the mounting position of the fixing element, they define a receiving space between them. With a suitably dimensioned leg width, the fixing element protects a further circumferentially enclosed receiving space on the opposite side of the wire mesh panel, which can also be used as a cable duct or for other purposes.

[0061] According to one embodiment of the invention, at least one pressure screw is used as a connecting means for connecting the first angle profile to a fixing element.

[0062] According to one embodiment of the invention, the components of the fence system are conductively connected to one another. This conductive connection allows fault currents from an electrical system present at any of the components to be dissipated into the ground. Grounding serves to prevent dangerous voltages and protect electrical systems and people from damage. The fence system components, due to their conductive connection, are conductive elements that are connected to the ground either directly or via additional connecting elements to ensure a good connection to the earth. If the metallic components are electrically insulating, painted, or otherwise coated, the coating can be bridged by bridging elements – such as screws that make direct contact with the metal.If the components of the fence system are made of an electrically non-conductive material, they can be provided with a conductive coating to ensure grounding.

[0063] According to one embodiment of the invention, the free-supporting ends of welded wire mesh panels are connected to each other by means of at least one first angle profile and at least one fixing element, which are attached to opposite sides of the welded wire mesh panels. Welded wire mesh panels are offered in standard widths, which, depending on the application, are not wide enough to bridge the gap between two adjacent posts. In such a case, it is possible to attach one side of a welded wire mesh panel to each post, whereby the width of the welded wire mesh panels is selected such that their free ends almost touch. The free gap between the free ends of the welded wire mesh panels can then be bridged by the first angle profile and the at least one fixing element.Since the angle profile and at least one fixing element bridge the free ends of the welded wire mesh panels and are inserted into the transverse wires in opposite directions via their slots, the first angle profile and the at least one fixing element interlock with each other, thereby also securing the free ends of the welded wire mesh panels to each other. In contrast to the example described above with two welded wire mesh panels, more than two panels can also be linked together in this manner. Because the welded wire mesh panels do not require downward support across their width, portals can be constructed using these panels, leaving openings underneath for material transport, conduits, passageways, and the like.

[0064] According to one embodiment of the invention, a vertically extending wire is held at each free-supporting end of the bridged welded wire mesh panels between one leg of the first angle profile and the at least one fixing element, such that the first angle profile and / or the at least one fixing element transmits tensile forces between the free ends of the welded wire mesh panels. This embodiment utilizes the vertically extending wires of the free ends of the welded wire mesh panels to generate resistance forces against pull-out movement of the legs suspended in the welded wire mesh panels and against oscillation movements of the free ends.

[0065] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. All features and combinations of features mentioned above in the description, as well as those subsequently mentioned in the description of the figures and / or shown in the figures alone, are usable not only in the combinations specified but also in other combinations, provided that no compelling technical obstacles prevent this.

[0066] The invention will now be explained in more detail with reference to preferred embodiments and the accompanying drawings.

[0067] They show: Fig. 1: A fence system from a frontal view, Fig. 2: A detailed view of the upper part of a post, Fig. 3a - 3c: different views of a first angle profile, Fig. 4: an alternative design for a fence system, Fig. 5: a close-up of the section containing circle B in Fig. 4 marked upper corner area, Fig. 6, Fig. 6a: an alternative design of a barred mesh mat, Fig. 7: a section of a fixing element, and Fig. 8: A possible way of attaching a post to a welded wire mesh panel, as seen from above. Fig. 9: A perspective view of a section of a wire mesh panel with a mounted cable duct, Fig. 10: a side view of a section of a mounted cable duct, and Fig. 11: A top view of a cable duct mounted on a wire mesh panel.

[0068] The Fig. Figure 1 shows a fence system 2 from a frontal view. A welded wire mesh panel 4 is attached to two posts 6 at its sides within the fence system 2. The welded wire mesh panel 4 is composed of a number of transverse wires 8 and vertical wires 10. The two posts 6 are supported on the ground by a base plate 12.

[0069] The Fig. Figure 2 shows a detailed view of the upper section of a post 6. The post 6 is composed of a first angle profile 12 and a second angle profile 14. In the illustrated embodiment, both angle profiles 12 and 14 are U-shaped. The first angle profile 12 has a leg 16a into which the welded wire mesh panel 4 with the transverse wires 8 is suspended. The second angle profile 14, whose leg 16b forms a fixing element 22, is placed on top of the first angle profile 12 and the transverse wires 8. Leg 16b overlaps leg 16a in certain areas. Leg 16b also penetrates the welded wire mesh 4 between the transverse wires 8. Legs 16a and 16b each have a screw hole 18 through which the two angle profiles 12 and 14 can be connected with a screw. The welded wire mesh 4 is bent at least once in its upper and / or lower area.

[0070] The Fig. Figures 3a-3c show different views of a first angle profile 12. Fig. Figure 3a shows a side view of the first angle profile 12 and thus of the leg 16a, which Fig. 3b a frontal view and the Fig. 3c a top view of the first angle profile 12. in the Fig. 3a and Fig. In Figure 3c, the free outer edges 24 are clearly visible, in which the openings 26 of the insertion slots 28 are located. The insertion slots 28 extend inwards from the free outer edge 24. The insertion slots 28 are parallel to each other and each has a channel width that corresponds at least to the wire thickness of transverse wires 8 of a bar mesh panel 4, with which a bar mesh panel 4 is suspended in insertion slots 28 located in the first angle profile 12. The insertion slots 28 formed in the first angle profile 12 extend, viewed from the openings 26, at least partially downwards into a plane below the respective opening 26. Fig. The shape of the U-profile is also clearly recognizable in 3c.

[0071] The Fig. Figure 3c also shows details of the base plate 20. The base plate is provided with three outriggers 30 with recesses 32 for ground anchors to facilitate wobble-free installation of the post, even on uneven ground. Shims can be placed under the outriggers 30 in the area of ​​the recesses 32 to further compensate for any unevenness in the ground. The top view shows the circumferential contours of the recesses 32, through which ground anchors can be inserted. The circumferential contours define holes of varying sizes. Depending on the load, ground anchors of different strengths can therefore be used. The base plate 20 can be welded to the first angle profile 12, or the base plate 20 can be bolted to the first angle profile 12.

[0072] The Fig. Figure 4 shows an alternative design of a fence system 2. The welded wire mesh panel 4 is designed in two parts: the upper part closes the gap between the two posts 6 in a conventional manner, while the lower part is designed as a gate 34. The lower welded wire mesh panel 4, designed as a gate 34, is framed by a frame 36, which is connected to one of the posts 6a via clamping brackets 38. The clamping brackets 38 and the frame 36 are connected to each other by hinges. On the side of the gate 34 opposite the post 6a with the hinges, another clamping bracket 38 is attached to the post 6b, which serves as a mounting for the lock case 40. The welded wire mesh panel 4 in the gate 34 has two recesses 42. The lower recess 42 serves to accommodate the bracket for the door handle and the lock, while the upper recess 42 serves as a window to allow monitoring of the interior of the fence system.In contrast to this embodiment, clamping brackets 38 can also be used for other fastening purposes. They can then be designed to suit the specific application. The clamping brackets 38 can be designed as a U-profile section, the opposite legs of which are tightened together at their free ends with clamping screws.

[0073] The Fig. Figure 5 shows a close-up of the upper corner area of ​​the Fig. In the embodiment shown in Figure 4, a mounting bracket 44 is attached to the post 6a by means of a plug-in tab 46 inserted into a slot 48. The first angle profile 12 even has two plug-in slots 48 into which two plug-in tabs 46 are inserted. The mounting bracket 44 can be inserted into and removed from the slots 48 without tools using the plug-in tabs 46. The mounting bracket 44 can be used to attach various components. In the illustrated embodiment, the mounting bracket 44 is hook-shaped and can therefore serve directly as a support for electrical cables or water pipes.

[0074] In the Fig. 4 and Fig. In the embodiment shown in Figure 5, the wire mesh panel 4 is not made of longitudinally and transversely running wires, but rather of a sheet metal panel from which the rectangular recesses 52 are punched or laser-cut. The remaining webs 50 between them form a grid-like structure. In contrast to the embodiment shown, any other shapes and patterns of recesses 52 and webs 50 can also be incorporated into the sheet metal panel. In the lateral edge region, however, the recesses 52 and webs 50 must be shaped and arranged so that they fit into the insertion slots 28 in the first angle profile 12 and the fixing element 22.

[0075] The Fig. Figure 6 shows an alternative embodiment of a barred mesh panel 4, which can be made, for example, from a metal sheet or other flat material to fill an area between two posts 6, as is also the case in the Fig. 4 and Fig. 5 is used. In the edge areas, the sheet metal plate is bent, as is particularly evident in the Fig. This can be seen in the enlarged section of the upper corner area shown in 6a, which is marked with circle A in the Fig. 6 is marked. In the enlarged view it is also clearly visible that the webs 50 formed in the edge area together with the beveled leg 54 form a channel for receiving tabs of the first angle profile 12 and the fixing element 22 inserted through the channel.

[0076] The Fig. Figure 7 shows a section of a fixing element 22. The fixing element 22 is provided with a number of insertion slots 28, by means of which the fixing element 22 can be placed onto the transverse wires 8 of the bar mesh panel 4 suspended in the first angle profile 12. The openings 26 of the insertion slots 28 are located in the fixing element 22 at the outer edge 24, which points in the direction of the insertion slots 28 in the leg 16a of the first angle profile 12. The insertion slots 28 in the fixing element 22 extend inwards from the outer edge 24 in a direction opposite to that of the insertion slots 28 in the first angle profile 12. The insertion slots 28 in the fixing element 22 have a parallel course to each other and each has a channel width that corresponds at least to the wire thickness of the transverse wires 8 of the bar mesh mat 4, which is hooked into the insertion slots 28 in the first angle profile 12.The insertion slots 28 formed in the fixing element 22 extend, at least in sections, from the openings 26 upwards into a plane above the respective opening 26.

[0077] The Fig. Figure 8 shows a possible mounting option for a post 6 at any point on a welded wire mesh panel 4 from a top view. The welded wire mesh panel 4 is folded over twice at its upper end by 90°. A first angle profile 12 with insertion slots 28 is placed onto the transverse wires 8 on one side of the vertical surface of the welded wire mesh panel 4. A fixing element 22 is then placed onto the transverse wires 8 on the other side of the welded wire mesh panel 4. Further components can now be attached to the first angle profile 12 and the fixing element 22. The first angle profile 12 and the fixing element 22 can also be supported on the ground, thus fulfilling the function of a post 6. The first angle profiles 12 and fixing elements 22 mounted in this way can also be used to frame an opening in the welded wire mesh panel 4, for example, openings for feeding material in and out.The first angle profile 12 and the fixing element 22 can be connected to each other by one or more cross braces.

[0078] The Fig. Figure 9 shows a perspective view of a section of a wire mesh panel 4 with a mounted cable duct 112. The cable duct 112 is composed of at least one first angle profile 114 and at least one fixing element 122. The cable duct 112 and the fixing element 122 are attached to the wire mesh panel 4 on opposite sides. The fixing element 122 is designed as a second angle profile 116 with at least two spaced-apart legs 118b. The first angle profile 114 is designed as a profile with a U-shaped cross-section, in which the legs 118a project at a right angle to the base 34. The two spaced-apart legs 118a of the first angle profile 114 define a receiving space 124 between them for receiving cables.

[0079] The Fig. Figure 10 shows a side view of a section of an assembled cable duct 112 in its installed position. The view reveals the transverse bars 8 and a longitudinal bar 10 of the wire mesh 4, particularly with highlighted lines in the center of the drawing. The outlines of the first angle profile 114 and the second angle profile 116 are shown superimposed in solid lines. The outline of leg 118a of the first angle profile 114 is highlighted in wider lines in the upper part of the drawing, and the outline of leg 118b of the second angle profile 116 is highlighted in wider lines in the lower part of the drawing. The first and second angle profiles 114 and 116 have a U-shaped cross-section and are connected to each other by a base 134.

[0080] The leg 118a of the first angle profile 114 has openings 128a at a free outer edge 126a for a number of insertion slots 130a, which extend inwards from the free outer edge 126a. The insertion slots 130a in the first angle profile 114 are parallel to each other and each has a channel width that corresponds at least to the thickness of transverse bars 8 of the welded wire mesh panel 4. In a vertical mounting position of the first angle profile 114 on the welded wire mesh panel 4, the insertion slots 130a extend upwards from the openings 128a. The first angle profile 114 is inserted into the welded wire mesh panel 4 such that transverse bars 8 of the welded wire mesh panel 4 are located in the insertion slots 130a. The fixing element 122 is connected to the first angle profile 114 via a connecting element 132.The connecting element 132 is shown only in dashed lines; in the illustrated embodiment, it is designed as a pressure screw which is connected to the first angle profile 114 via a thread 136 and is supported by the pressure head 138 on the inside of the second angle profile 116.

[0081] The Fig. Figure 11 shows a top view of a cable duct 112 mounted on a wire mesh panel 4. In this view, it is clearly visible that the first angle profile 114 and the fixing element 122, which in the exemplary embodiment is designed as a second angle profile 116, are arranged on opposite sides of the wire mesh panel 4. The receiving spaces 124a and 124b are also clearly visible in this view. It is also clearly visible that these receiving spaces 124a, 124b are enclosed in the transverse direction by the angle profiles 114, 116 and the transverse bars 8 of the wire mesh panel 4.

[0082] The invention is not limited to the above embodiments. It will not be difficult for a person skilled in the art to modify the embodiments in a manner that appears suitable to them in order to adapt them to a specific application.
