Description

The invention relates to a mounting rail, in particular for applications in the field Building technology, according to the preamble of claim 1.

The field of home technology includes assembly applications in the electrical and sanitary sector, in the heating sector as well as in ventilation and air conditioning technology. To a high Flexibility, for example when laying cables, pipes and the like, too are often not directly on a wall, ceiling or floor installed, but first mounting rails are attached to which suitable Fasteners for the cables, pipes and the like are attached. Of the The use of mounting rails makes it very quick and easy if necessary Moving attachment points for cables, pipes and the like without this new holes must be drilled to anchor the fasteners. The fasteners can be easily moved along the mounting rail and be installed at the desired location. Mounting rails are also used for others Areas of application, for example to hang false ceilings Luminaires can be flexibly installed locally, etc. to be used wherever there is great flexibility in the arrangement of Attachment points is desired.

Mounting rails are known from the prior art which have a rectangular or have a square cross-section and dovetail-like on all four sides are profiled. In this way, fasteners can be on all four outer sides be fitted with connecting parts which correspond to the dovetail-like Side profiling are formed. Mounting rails are also known, which have an approximately C-shaped cross section. This one-sided open Mounting rails are mounted with their closed back on the surface or suspended from the ground. The fasteners are on the side or inserted on the face side into the open slot and, for example, by turning the Connection part mounted in the rail. Some of these well-known C-rails have at the edge of the open slot an inward toothing, which with a corresponding teeth on the connecting part of a fastener interacts and this against unintentional movement in the Mounting rail secures.

These known mounting rails have for the respective application Advantages on. C-rails are preferred for suspensions because they are simple Allow mounting of the fasteners, their connecting parts relatively easy can be designed. The hanging connection of the fasteners is easy to accomplish; moving the fasteners in the mounting rails with Internal toothing is easy to loosen and reassemble Fasteners can be carried out. Dovetail-shaped Mounting rails with connection options on the outer surfaces of the rail are very suitable for rail constructions where several rails are used connected to each other, for example to create a frame.

One is from EP-A-0 638 758, which forms the generic prior art Mounting rail, especially for applications in the field of building technology, known. she consists of an elongated rail body of approximately C-shaped cross section, the a perforated back wall and protruding from it at right angles Has side walls. The side walls are on their opposite the rear wall free end forming two substantially parallel to the back wall extending webs bent and bordered one in the longitudinal direction of the Mounting rail running slot.

The known mounting rail has longitudinal and transverse beads in its wall parts, the serve to stiffen the sheet material. In particular, to improve rigidity Double beads are provided, which are S-shaped or Z-shaped in cross section. The double beads each consist of two parallel beads, the opposite Directions from the sheet metal plane of the side walls and the rear wall deformed are immediately merged. The outer surfaces of the Mounting rail always surmounted by at least one bead. This has the disadvantage that the mounting rail with its rear wall or with a side wall is not in flat system comes to the underground, but always only on the outside facing beads. Through the outward facing beads in the Sidewalls, the width of the mounting rail does not match the width of the back surface; rather, this is determined by those areas of the beads that the Most protrude from the outer surfaces of the side walls. This can be a precise location It is difficult to position and fasten the mounting rail. Dimensional tolerances at The deformation of the beads can, for example, in the arrangement of the mounting rail lead to great difficulties in an underfloor duct. To the angled flanges that border the longitudinal slot are suitably designed Attachment elements attachable. There are no other connection options intended.

The object of the invention is to provide a mounting rail which is universal can be used. The mounting rail is designed with various connection systems be compatible to allow different types of fastenings for are best suited to the respective application. It is supposed to be a mounting rail be created that is suitable for arrangement on the ceiling, wall and floor and can also be installed at a distance from the ground. The mounting rail should in particular Suspensions allow and should also create frame-like constructions enable.

These tasks are solved by a mounting rail, which the in characterizing section of claim 1 has listed features. The Mounting rail according to the invention, in particular for applications in the field Domestic engineering, consists of an elongated rail body of approximately C-shaped Cross section; the one with perforations and at right angles from it has protruding side walls. The side walls are on the back wall opposite free end forming two substantially parallel to the The rear wall of the extending webs is bent and bordered one in the longitudinal direction of the Mounting rail running slot. Profiles are in each side wall provided that extend over the length of the mounting rails. The Profiles in the opposite side walls are symmetrical to each other arranged and have a depth which is the width of the edge of the slot Do not exceed webs.

Because the C-rail is equipped with profiled side walls, the Mounting rail can be used universally and for attachments to the ceiling on the Suitable for walls and floors and for installations at a distance from the surface. The C-profile open on one side allows the connection of fastening elements, their Connecting parts can easily be inserted into the slot. That way it is mounting rail according to the invention in the usual way together with Suspension elements can be used. Those in the side walls are symmetrical to each other arranged profiles increase the possible uses of the mounting rail, by also connecting parts and connecting parts for the rails, which on the along the Profiles running in the side walls are matched to the Mounting rail are attachable. In this way, the mounting rails for example, to be assembled into a frame system. The Mounting rail can also be used in connection with fasteners be, which encompass the mounting rail or through the open slot in the Are fixed inside the rail. The connecting parts are hook-like in the Profiling inserted or hung. The combination of longitudinal slot and longitudinal running profiles also allows the connection of several different ones Fasteners on the same length section of the mounting rail. This can be from Be advantageous if, for example, a side wall or the slot of the mounting rail is difficult or impossible to access due to spatial conditions. Instead of how so far, in such cases move the attachment point or the The mounting point can be implemented by choosing the mounting rail a fastener adapted to the given space conditions maintain a connection part that is matched to the accessible profiles become. By the depth of the profiles the width of the edges of the longitudinal slot The slim line of the mounting rail is retained. The Profiles in the side walls of the mounting rail increase the bending stiffness and thus the permissible load. This makes the mounting rail lighter become.

It turns out to be useful if the symmetrical profiles formed, facing inner surfaces of the side walls projecting Wall sections have a distance from each other, the width of the slot corresponds. In this way, the obstacles protruding into the rail interior Wall sections of the profiles that engage in the longitudinal slot Connecting parts of fasteners are not, and these can be used in the usual way Be moved longitudinally along the mounting rail.

By forming the symmetrical profiles, the outer surfaces of the Corresponding wall sections of the profiles protruding from the side walls have a distance from one another which corresponds to the width of the rear wall, the total width of the mounting rail corresponds to the width of the rear wall. By the longitudinal profiles arranged in the side walls become the External dimensions of the mounting rail have not been changed.

In an advantageous embodiment of the invention, the profiles have a dovetail cross section. They cover each side wall at least one groove-like depression, which starts in one side wall Extends towards the opposite second side wall, the groove-like Undercut is formed and a smaller on the side wall Has slot width than at the bottom of the groove. Through the longitudinal grooves with dovetail-like cross-section in both side walls arise inside the rail hook-like projections, which are easy to hook Allow fasteners. Also encompassing the mounting rail Fastening elements can be hooked into the longitudinal grooves very easily. The dovetail-like longitudinal grooves are particularly suitable for receiving Correspondingly trained connecting parts of fasteners formed, which are attached to the outer surfaces of the side walls. Here the dovetail shape has the advantage that the mounted fastening part, is supported in the longitudinal groove, in particular in the case of a lateral connection.

The undercut groove-like depressions are advantageously symmetrical in themselves formed, their side surfaces opposite the vertical on the side wall of the Mounting rail are inclined at an angle of approximately 10 ° to approximately 25 °. The Angle of inclination of the side surfaces of the groove-like depressions result in hook-like Connection areas that are sufficiently deep. The symmetrical training the groove-like depressions ensures in all positions of the mounting rail comparable conditions for the connection of fasteners. Especially preferred positions for fastenings on the side walls are avoided.

For the bending stiffness of the mounting rail, it proves advantageous if the parallel webs running to the slot have a greater wall thickness than that Side walls. The increase in wall thickness is preferably by flanging the webs in the direction of the associated side wall. By the wall thickness of the Is increased, the permissible load of the mounting rail is increased.

The wall thickness increase of the webs also has the advantage that the Provide knurling or toothing on the rear wall facing side of the webs can be. Knurling or toothing allows in connection with suitable trained connecting parts a pre-fixation of the fasteners. After Fixing the fasteners increases the knurling or gearing permissible shear load.

The connection options for different fasteners are at Mounting rail according to the invention is further enlarged in that in the Perforations are provided on the side walls, in a grid or in an integer Multiples of the grid of the rear wall perforations are arranged. Through the perforations In the side walls, for example, bolts can be pushed through other elements are suspended or fastened in another way. For example Cable ties can be easily inserted through the perforations in the side walls, to tie up cable strands in this way, etc. By punching the holes in the Sidewalls in the grid or in an integer multiple of the grid of Back wall perforations are arranged, can be avoided that when cutting the Mounting rail sawn holes or perforations on the edge of the rail occur. Is used when cutting the mounting rail in the area between two Back panel perforations said that there is none in the side walls Perforations are sawn through.

The back wall perforations advantageously consist of a periodic sequence of Holes of different diameters and contours together. This allows the Use of different types of fasteners with different Diameters and contours based on the specific application and / or the underground are optimized. The back wall perforations are periodic recurring sequence what the preparation, such as drilling, of the base for the mounting of the rail easier. Preferably, the Perforations arranged in a centimeter grid.

A particularly good ratio of dead weight and permissible load capacity of the Mounting rail results for wall thicknesses of approximately 0.5 mm to approximately 2.0 mm. Out For reasons of corrosion protection, the mounting rail is made of sheet steel, which is galvanized, is preferably pre-galvanized, or consists of a stainless steel alloy.

The invention is explained in more detail below with reference to exemplary embodiments illustrated in the drawings. Show it:
