MOUNTING DEVICE WITH AN EXTENSION

Description

[0001] The invention relates to a mounting device with a boom.

[0002] These mounting devices are used in installation technology and are designed to support loads such as cable ducts, cable trays, and cable ladders, as well as the media lines they support, such as electrical cables, water pipes, and the like. The mounting devices comprise a support profile, e.g., a ceiling support, to which at least one bracket is mounted on one side or on opposite sides. Brackets are traditionally bolted to the support profile.

[0003] [1], EP1155638A1, discloses a boom that can be detachably mounted on a ceiling support provided with mounting holes for this purpose. The boom consists of a support arm used to support the load and a head piece connected to it, which also has a mounting hole. The boom is mounted using hook-shaped connecting elements that are inserted into the mounting holes. The boom can therefore be mounted on the ceiling support at a selectable height and, depending on the type of ceiling support, (z.B. The disadvantage of this bracket is that it is very complex to manufacture. The support arm is welded to the corresponding mounting part, which not only involves considerable effort but also has other disadvantages.

[0004] On the one hand, it's important to note that booms often carry heavy loads and are therefore subject to severe mechanical stress. Poor welds can crack, rendering the load unsafe.

[0005] Although the connectors can create a positive connection between the boom and the ceiling support without the use of screws, handling the hook-shaped connectors during installation, especially while standing on a ladder close to the ceiling, poses considerable difficulties. Especially at low temperatures, it is often difficult for the installer to insert the relatively small connectors into the selected opening in the ceiling support and the opening in the boom head. Wearing protective gloves further complicates the installation process.

[0006] [2], EP1804354A2, discloses a support profile having elongated holes at regular intervals and a bracket that can be connected to the support profile by an adapter. The bracket has a front plate with an opening on the side facing the support profile. The adapter comprises a plate that can be hooked into a longitudinal opening of the support profile on one side with at least one first hook and has a second hook on the other side that can be hooked into the opening of the front plate of the bracket. After the bracket has been installed and a cable tray has been placed on it, the second hook of the adapter connected to the bracket and the front plate of the bracket are subjected to high tensile forces, resulting in limited load-bearing capacity. The second hook, which is cut out and shaped from the adapter and is subjected to tensile stress, can deform further, causing the bracket to tip over under increased load.It should be noted that during the installation of cable trays and cable ducts, very high loads often act on the booms. This can happen, for example, if the installer leans on the installed cable tray or cable duct. In such cases, there is a safety risk even for the installer if the boom should become loose.

[0007] It should be noted that even with this solution, the assembly of the boom is difficult if the installer is wearing gloves.

[0008] Another disadvantage of this solution is that the boom can easily come loose if the installer bumps into it. For example, if the boom is impacted from below, it can easily become detached from the hook. A stable and secure connection is only achieved once a load has been placed on the boom.

[0009] Another disadvantage of known cable routing devices is that mechanical forces are transmitted undamped over large distances, so that noises can spread and strong forces can also act on distant device parts, which can possibly result in the device parts becoming loose.

[0010] [3], EP 2846428A1, discloses a mounting device with an angle element, by means of which cable tray elements of a cable tray that are differently aligned to one another and held by brackets can be connected to one another. The angle element has one or more segments that are tailored such that the cable tray elements, aligned at a corresponding angle to one another, can be connected to one another. Since segments are not available in any shape, only certain mutual orientations of the cable tray elements can be realized. Furthermore, the one-piece angle element is relatively bulky and can only be manufactured and installed with corresponding effort.

[0011] EP3664236A1 discloses a mounting device comprising at least one support profile having a side part provided with a series of regularly spaced profile openings, and a bracket connected to the support profile. The bracket comprises a head piece having an elongated connecting part and connected to one of the side parts of the support profile, and a support arm connected to the head piece, which comprises a support plate to which an angled side plate adjoins on both sides.

[0012] EP0575269A1 discloses a device for suspending cable ducts, comprising a support profile having a side part provided with a series of regularly spaced profile openings, and brackets connected to the support profile. The brackets each comprise a head piece that is screwed to the side part of the support profile.

[0013] EP2846428A1 discloses an angle element for cable carriers and a cable carrier with this angle element.

[0014] The present invention is therefore based on the object of creating an improved mounting device with a support profile and a boom.

[0015] The mounting device should be able to advantageously install any cable routing devices, such as cable trays, cable ladders or wire mesh trays.

[0016] The boom and the assembly device with the support profile and the boom should be simple in design and be able to be manufactured with low labor costs and high quality.

[0017] The mounting device should preferably allow the installation of cable routing devices that are aligned parallel to each other or form any angle to each other. Complex angle elements should be eliminated. The mounting device, which comprises one or more support profiles, should make it particularly easy to install cable routing devices that can have any desired layout with multiple changes of direction.

[0018] Booms should be designed to be particularly simple and can be assembled with just one movement, possibly with just one hand. In particular, the boom should be easy and safe to install, even by installers wearing protective gloves.

[0019] The installation of the boom should immediately result in a stable and secure connection between the boom and the support profile. Accidental release of the boom due to careless movement against the boom should be virtually impossible.

[0020] In cable routing devices comprising mounting devices according to the invention, acting forces should preferably not be transmitted over large distances and the transmission of noise should be prevented.

[0021] This object is achieved with a mounting device with a support profile, which has the features specified in claim 1. Advantageous embodiments of the invention are specified in further claims.

[0022] The mounting device comprises a support profile, preferably a ceiling support, which has at least one side part provided with a series of profile openings preferably regularly spaced from one another, and a boom connected to the support profile, which boom has a head piece connected to one of the side parts, and a support arm connected to the head piece, which comprises a support plate to which an angled side plate is connected on one or both sides.

[0023] According to the invention, the head piece has an elongated connecting part to which a hook-shaped holding part is connected, wherein the elongated connecting part is inserted through a first profile opening within the support profile to a second profile opening at which the holding part protrudes from the support profile and is suspended on the support profile, and that an end piece of the at least one side plate rests adjacent to the first profile opening on the associated side part of the support profile.

[0024] The support profile and the boom can be manufactured cost-effectively and with high quality using simple tools, if necessary as a single piece from a metal plate or sheet. It is advantageous to use raw materials with a protective coating that is not, or only minimally, damaged during processing. For example, Sendzimir galvanized metal pieces are used to manufacture the booms.

[0025] The support profile and the boom can advantageously be manufactured in one piece, resulting in low manufacturing costs and high strength of the support profile and the boom as well as the assembled assembly device.

[0026] The cantilever can be installed particularly easily by inserting the connecting piece, guided by the retaining piece, into the first profile opening and guiding it to the second profile opening, where it is hooked in. During this process, the cantilever rotates almost automatically, rotating it from an inclined position to an alignment parallel to the support profile. After this rotation, the end piece of at least one side plate rests against the corresponding side part of the support profile, preventing further rotation of the horizontally aligned cantilever, even when loaded.

[0027] The end piece of at least one side plate or the end pieces of the two side plates of the cantilever can preferably be countersunk into recesses on the corresponding side part of the support profile. The recesses are preferably designed as grooves or channels, which preferably serve as guide rails. The assembled cantilevers are therefore automatically held in the desired orientation and can, if necessary, slide along the recesses or guide rails under load if the head piece, the connecting part, or the holding part are elastically designed or if an elastic part is provided.

[0028] The boom can therefore be grasped by the support arm with one hand and easily connected to the support profile using the described movement. The assembly process can be carried out with one hand, protected against cold and injury by a glove if necessary. The installer, standing in an exposed position, for example, on a ladder, thus has one hand free to protect themselves while assembling the boom with the other hand in one easy movement.

[0029] A particularly advantageous feature is that, after simple installation, the brackets according to the invention no longer detach from the support profile, even under accidental force. After manual installation, the brackets can only be released from the support profile by a specific release movement, thus preventing accidental or spontaneous detachment. Despite, and also because of, the simple design of the mounting device, this results in increased operational reliability.

[0030] The first and second profile openings can follow one another directly or be separated from one another by at least one third profile opening. Furthermore, the first and second profile openings can be provided on the same side part of the support profile or on opposite sides of the support profile. The first profile opening is located above or below the second profile opening. Based on the present invention, brackets can therefore be advantageously implemented that are suspended from the support profile in different ways, with the connecting part always running within the support profile or on the rear side of the side part of the support profile to which the bracket is attached.

[0031] In preferred embodiments, the connecting part and / or the holding part are designed to be resilient. Alternatively or additionally, the holding part can be provided with a resilient part, a metal spring, or a plastic element, optionally protected by metal elements, which is supported on a corresponding part of the support profile. This easily imparts elasticity to the mounting device, allowing it to dampen acting forces, in particular vibrations and noise, and prevent them from propagating further.

[0032] The holding part preferably has a terminal part that runs at least approximately parallel to the connecting part and is directed with its free end toward the support arm of the boom. The terminal part is preferably tongue-shaped and bent outward at the end so that it can easily enter the second profile opening.

[0033] Preferably, the end piece is curved and / or spring-loaded so that it can hold the gripped side piece without play. A light tap on the support profile allows the boom to be moved to its end positions or released again.

[0034] In preferred embodiments, the preferably spring-elastic end part of the holding part is designed as a locking element, so that it can engage in a recess or profile opening in the support profile. When the bracket is inserted, a locking connection is automatically created, which secures the bracket. This locking connection can be easily released again, for example, by bending back the end part with a screwdriver.

[0035] The connecting part and / or the holding part preferably have at least one through-opening for the passage of a locking screw or mounting screw. In preferred embodiments, a through-opening of the connecting part and a through-opening of the holding part are arranged coaxially to one another so that a locking screw or a mounting screw can be guided through both through-openings. At least one of the through-openings is preferably designed as a threaded bore into which a locking screw or a mounting screw can be screwed. The bracket can be locked to the support profile by means of the locking screw, which is screwed, for example, into a third profile opening provided between the first and second profile openings. Alternatively, a bracket can also be fastened to a wall by means of a mounting screw.

[0036] Furthermore, a mounting device with a boom is disclosed which can be connected to a support profile as described or in another way and which has a head piece and a support arm which is preferably connected integrally to the head piece and which comprises a support plate to which an angled side plate is connected on one or both sides. The support plate of the support arm is wider than the support profile so that opposite ends of two cable routing devices can be placed and preferably fixed on the support plate. Mounting elements or wing elements, for example, are provided to hold the cable routing device. Cable routing devices such as cable trays, cable ladders or wire mesh trays can be aligned parallel to one another on the support plate or optionally angled relative to one another so that they enclose an angle in the range of, for example, 90° to 270°.Instead of an angle piece, a correspondingly designed bracket is therefore provided. Brackets with a widened support plate are preferably mounted on the mounting device, which comprises several spaced-apart support profiles mounted, for example, on the ceiling, at the points where the ends of two cable routing devices, which may be inclined relative to each other, are to be held. Complex angle pieces and their assembly can therefore be dispensed with. DESCRIPTION

[0037] One or more outriggers can be attached to a support profile on each side panel at a selected height.

[0038] The profile openings in the support profile are identical or different, e.g., rounded or polygonal, and arranged at a regular or irregular spacing. At least two of the profile openings, or a first profile opening and a second profile opening, and the length of the connecting part are selected to match each other. If the spacing of the profile openings is regular, the brackets can be moved and installed in equal steps. The invention is explained in more detail below with reference to the drawings. Herein: Fig. 1a shows a mounting device 3 according to the invention with a support profile 2, which has three side parts 2A, 2B, 2C provided with profile openings 21, 22, and with a boom 1, which comprises a support arm 11 with a support plate 111, to which an angled side plate 112 is connected on each side, and a head piece 12, which is connectable to the support profile 2 and which has an elongated connecting part 121, to which a hook-shaped holding part 13 is connected; Fig. 1b the boom 1 of Fig. 1a mounted on a wall (not according to the invention); Fig. 2a the mounting device 3 with the support profile 2 and the bracket 1 of Fig. 1a when inserting the holding part 13 and the connecting part 121 into a first profile opening 21A on the side part 2B of the support profile 2; Fig. 2b the mounting device 3 of Fig. 2a after the complete passage of the connecting part 121 through the first profile opening 21A; Fig. 2c the mounting device 3 of Fig. 2b after rotating the boom 1 and screwing the holding part 13 into a second profile opening 21B; Fig. 2d the mounting device 3 of Fig. 2c after vertically moving the boom 1 and hanging the holding part 13 on the side part 2B; Fig. 3a the mounting device 3 in the position of the boom 1 of Fig. 2c with a locking screw 8, which is inserted into openings 120 (see Fig. 1a ) and 130 in the connecting part 121 and in the holding part 13; Fig. 3b the mounting device 3 of Fig. 3a after vertically moving the boom 1 and hanging the holding part 13 on the side part 2B as well as locking the boom 1 by screwing in the locking screw 8; Fig. 3c the holding part 13 of the boom 1 with an end part 131, which has a locking element 1311 that can lock into the adjacent profile opening 22; Fig. 4a the mounting device 3 of Fig. 3a with a preferably designed boom 1, whose support arm 11 has a wider support plate 111, stabilizing elements 1121, 1121S and holding elements 1111; Fig. 4b the boom 1 of Fig. 4a with a perforated support plate 111, not covered by claims; Fig. 5 a mounting device 3 with the boom 1 of Fig. 4b and 2 cable trays 4A and 4B placed thereon; Fig. 6a the mounting device 3 of Fig. 5 with deflectable wing profiles 5A, 5B, not covered by claims; and Fig. 6b the mounting device 3 of Fig. 6a with deflected wing profiles 5A, 5B, not covered by claims.

[0039] Fig. 1a shows a mounting device 3 according to the invention with a support profile 2, e.g. a ceiling support mountable on a ceiling, and with a boom 1 mountable on the support profile 2.

[0040] The support profile 2, preferably made from a single piece of metal, is a multiply folded metal sheet having three side parts 2A, 2B, 2C, each provided with profile openings 21, 22 arranged at regular intervals. On the fourth side, the end pieces of the support profile 2 are turned inwards towards each other in a claw-like manner and each provided with a row of teeth. The support profile 2 is shown as an example and can have any side parts and identical or different, rounded or polygonal profile openings. For the present invention, it is essential that at least one side part 2A, 2B or 2C is provided with profile openings suitable for suspending the boom 1. The boom 1, preferably made in one piece from a single piece of metal, comprises a support arm 11 and a head piece 12. The support arm 11 has a support plate 111, to which an angled side plate 112 is connected on each side.The headpiece 12, which can be connected to the support profile 2, comprises an elongated connecting part 121, to which a hook-shaped retaining part 13 is connected. The length of the connecting part 121 is selected according to the distance between the profile openings 21, 22 of the support profile. If different materials are used for the support arm 11 and the headpiece 12, they can also be connected to each other. For example, the headpiece 12 is made of a resilient metal.

[0041] In Fig. 1a an elastic element or a spring is shown, which symbolizes that the connecting part 121 is preferably elastic or the holding part 13 is provided with an elastic element, z.B. a plastic buffer. The connecting part 121 can be made of spring steel and / or provided with a wave shape.

[0042] In this preferred embodiment, the holding element 13 has a terminal part 131 aligned parallel to the connecting part 121 and with its free end pointing towards the support arm 11. The terminal part 131 is provided with a through-opening 130 arranged coaxially with a through-opening 120 in the connecting part 121. Preferably, at least one of the through-openings 120, 130 is provided with a screw thread into which the locking screw or mounting screw 8 shown can be screwed. By means of the screw in the form of a locking screw 8, the boom 1 mounted on the support profile 2 can be locked. Using the screw 8 in the form of a mounting screw, the boom 1 can alternatively also be mounted on a wall 9.

[0043] The Figuren 2a , 2b , 2c and 2dshow the simple process of mounting the boom 1 on the support profile 2. This process can be performed quickly and safely with just one hand, protected by a glove if necessary. The support profile is cut along its longitudinal axis, so the assembly process is clearly visible.

[0044] Fig. 2a shows the mounting device 3 with the support profile 2 and the boom 1 of Fig. 1a when inserting the holding part 13 and the connecting part 121 into a first profile opening 21A on the side part 2B of the support profile 2. For this purpose, the boom 1 is rotated slightly counterclockwise so that the holding part 13 can be inserted into the first profile opening 21A.

[0045] Fig. 2b shows the mounting device 3 of Fig. 2a after the connecting part 121 has been completely passed through the first profile opening 21A. The boom 1 is now rotated clockwise so that the end part 131 of the holding part 13 can be passed through the second profile opening 21B.

[0046] In Fig. 2b Preferably provided recesses 201 in the side part 2B are symbolically shown by dot-dash lines. The recesses 201 are intended to accommodate the end pieces 1121 of the side plates 112. After the end pieces 1121 are screwed into the recesses 201, the boom 1 is held immobile laterally. The boom 1 can only be moved vertically upwards and downwards along the recesses 201, which form guide rails. The recesses are, for example, longitudinal grooves or stepped edges.

[0047] Fig. 2c shows the mounting device 3 of Fig. 2b after rotating the boom 1 and screwing the holding part 13 with the exposed end part 131 into the profile opening 21B. In this position, the support arm 11 is aligned at least approximately horizontally. The connecting part 121, which is preferably inclined by 90°, runs at least approximately parallel to the longitudinal axis of the support profile 2. To complete the assembly process, the boom 1 is now simply moved vertically downwards.

[0048] Fig. 2d shows the mounting device 3 of Fig. 2c after the vertical displacement of the boom 1 downwards and the resulting hooking of the holding part 13 onto the side part 2B.

[0049] Fig. 3a shows the mounting device 3 in the position of the boom 1 of Fig. 2c with a locking screw 8, which fits into the through holes 120 (see Fig. 1a ) and 130 in the connecting part 121 and in the holding part 13.

[0050] Fig. 3b shows the mounting device 3 of Fig. 3a after vertically moving the boom 1 and hanging the holding part 13 on the side part 2B as well as locking the boom 1 by screwing in the locking screw 8.

[0051] Fig. 3c shows the holding part 13 of the boom 1 with an end part 131, which has a locking element 1311 that can lock into the adjacent profile opening 22. The end part 131 is preferably tongue-shaped and / or elastic, so that it can easily overlap the second profile opening 21B and, with the locking element 1311, can re-enter the adjacent profile opening 22. After assembly of the boom 1, it is thus automatically secured by the locking connection even without inserting a locking screw. The locking connection can be easily released again, e.g., using a screwdriver by lifting the end part 131.

[0052] Fig. 4a shows the mounting device 3 of Fig. 3a with a support profile 2 and a preferably designed boom 1, the support arm 11 of which has a wider support plate 111. The support plate 111 is wider than the facing side of the support profile 2, on which the boom 1 is suspended. Typically, the booms 1 are narrower than the support profile 2 or have approximately the same width. Preferably designed booms 1, on the other hand, have a support plate 111 that is wider than the support profile 2 or the facing side of the support profile 2. The width of the support plate 111 can be greater than the width of the support profile 2 by a factor in a range of preferably 1.5 - 10 or more. The width is preferably selected according to the corresponding cable routing devices and their type of installation.

[0053] The support plate 111 can be designed symmetrically or asymmetrically. Furthermore, the support plate 111 can be rectangular, triangular, or polygonal.

[0054] The support plate 111 may also have stabilizing elements such as beads, deformations and the like.

[0055] The angled side plates 112 adjoining the support plate 111 have optionally provided exposed angular end pieces 1121, which are directed from both sides against the support profile 2 and enclose it between them. The end pieces 1121 of the side plates 112 can also be guided straight backward and provided with threaded holes into which screws 1121S are inserted, which are screwed against the support profile 2 in order to fix the boom 1 relative to the support profile 2. Furthermore, it is possible to provide collar-shaped end pieces of the support plate 111 of the support arm 11, which partially enclose the support profile 2. In particular, if the head piece 12 of the boom 1 is held in the associated opening with virtually no play, such stabilizing parts can be dispensed with.

[0056] In this preferred embodiment, holding elements 1111 are provided on the support plate 111, which allow a cable guide device to be fixed thereon.

[0057] Fig. 4b shows the boom 1 of Fig. 4a with a support plate 111 having mounting openings 1110 that allow a cable guide device to be fixed thereon. Preferably, the support plate 111 of the inventive bracket 1 has retaining elements 1111 according to Fig. 4a and / or mounting openings 1110 according to Fig. 4b on.

[0058] Fig. 5 shows a mounting device 3 with the boom 1 of Fig. 4b and two cable trays 4A and 4B placed thereon, each of which, in this preferred embodiment, has a base plate 41 with longitudinal perforations 410 and side walls 42 adjoining it on both sides. Instead of the cable trays shown, any other cable routing devices, such as cable trays, wire mesh trays, or the like, can be placed thereon.

[0059] The cable guide devices 4A, 4B, which rest with their ends on the support plate 111, can be rotated relative to each other in both directions over a wide range. In the configuration shown, the cable guide devices 4A, 4B enclose an angle a on the facing side that is less than 180°. However, the cable guide devices 4A, 4B can also be rotated such that they enclose an angle a on the facing side that is less than 180°. The angle a is typically in the range of 90° - 270°, with the angle a typically in the range of 135° - 225°.

[0060] It is evident that the cable routing devices 4A, 4B or cable trays can be selectively rotated relative to one another and easily fixed in a specific position. For this purpose, for example, at least one fixing element or mounting element 1111, such as a screw or a pin, is passed through an opening 410 in the base plate 41 of the cable tray 4 and further through a corresponding mounting opening 1110 in the support plate 111. The mounting element 1111 can be connected to the support plate 111 or inserted by the installer. Alternatively, cable ties can also be passed through the mounting openings 1110 and the longitudinal perforations 410.

[0061] In the illustrated embodiment, a triangular portion of the support plate 111 is kept free between the ends of the cable guide devices 4A, 4B, which connects virtually seamlessly to the base plates 41 of the cable guide devices 4A, 4B. The ends can also connect to each other across the entire width of the cable guide devices 4A, 4B if they are adapted to each other at the front by bevel cuts SA, SB or SA', SB'.

[0062] The bracket 1 therefore forms a connecting piece for connecting cable trays 4A, 4B. The brackets 1 can have any designed head pieces 12, which can be connected to the mounting profile 2 in any way, z.B. hung or screwed.

[0063] Fig. 6a shows the mounting device 3 of Fig. 5 with deflectable wing profiles 5A, 5B, which have base pieces 51 with longitudinal openings 510 and side pieces 52 with longitudinal openings 520. The wing profiles 5A, 5B are held in a preferably rotatable and fixable manner by the support plate 111 or the holding elements 1111 provided thereon or by further mounting elements. In the embodiment shown, the wing profiles 5A, 5B are parts cut out of a cable tray 4 or 4A and 4B. Since the cable trays 4 or 4A and 4B are stackable, they can also be inserted into the wing profiles 5A, 5B without play and can be easily fixed. For example, cable ties are inserted through the openings 420, 520 in the side walls 42 of the cable trays 4A and 4B and the side pieces 52 of the wing profiles 5A, 5B.

[0064] Fig. 6b shows the mounting device 3 of Fig. 6a with deflected wing profiles 5A, 5B, which can be easily fixed in the respective position, preferably by means of screw sets or cable ties.

[0065] The mounting device 3 can further comprise a plurality of mounting profiles 2, each with at least one boom 1. For example, the mounting device 3 according to the invention is used to realize a cable route, which at each point of a path change has a mounting profile 2 with a boom 1 according to Fig. 5 or 6a As mentioned, the preferably designed brackets 1, which form a connecting piece or an angle piece, can be connected to the mounting profile 2 in any manner.
