Description

Angle connector for mounting guide rail
Technical Field
The invention relates to an angle connector for mounting rails having the features of the preamble of claim 1.
Background
The mounting rail is, for example, suspended below a ceiling or fastened horizontally or vertically at a ceiling, wall, column or the like and is used for fastening and/or laying cables, cable trays, pipelines, wiring boards or the like. The mounting rail is usually made of sheet metal by bending and has a rectangular tube profile which is open at one point and which has longitudinal grooves running through in the longitudinal direction in the longitudinal sides. In the longitudinal side opposite the longitudinal groove, the known mounting rail has holes spaced apart in the transverse center, in particular round, oblong and/or square holes. In the other longitudinal side, the mounting rail can also have a hole. The invention is not limited to the described mounting rail.
In order to fasten the ends of the mounting rails at the longitudinal sides of the first mounting rail, angle connectors with a U-shaped profile are known, which are arranged or arranged transversely or obliquely to the first mounting rail, the inner cross section of which corresponds to the outer cross section of the first mounting rail. In the following, the mounting rail, the ends of which are fastened at the longitudinal sides of the first mounting rail, at which the mounting rail arranged transversely or obliquely thereto is fastened, is also referred to as "second mounting rail" or "butted mounting rail", and the first mounting rail is referred to as "butted mounting rail". When the mounting rail extends horizontally, the angle connector is placed from above onto the first mounting rail, wherein it is oriented such that its U-shaped contour is open at the bottom. At one side, the angle connector has another oppositely directed U-shaped profile. By "oppositely directed" is meant that the U-shaped profile is open at opposite sides. The other U-shaped profile is located at the longitudinal side of the first mounting rail when the angle connector is placed onto the first mounting rail, and the other U-shaped profile is open above when the angle connector is placed with its open side onto the first mounting rail from below upwards. The other, upwardly open U-shaped profile forms, at the longitudinal sides of the first mounting rail, fastening means for the end of the second mounting rail, which are arranged or arranged transversely or obliquely to the first mounting rail, into which fastening means the end of the second mounting rail can be inserted or, in general, with which fastening means the end of the second mounting rail can be fastened at the longitudinal sides of the first mounting rail.
Patent application EP1561956 a1 discloses a two-part or multi-part angle connector for mounting rails, which has a U-shaped profile that can be placed onto a first mounting rail from above, which U-shaped profile has a groove in its side faces, on each of which side faces a further U-shaped profile can be hung with its opening into the groove opposite the opening of the angle connector as a fastening means for the end of the mounting rail. When the U-profile hangs at the side of the angle connector, the lug of the other U-profile engages under the longitudinal edge of the angle connector, so that the U-profile can not be lifted.
Disclosure of Invention
The object of the invention is to provide an angle connector for a mounting rail, which angle connector can be easily fastened to the mounting rail.
According to the invention, this object is achieved by the features of claim 1. The angle connector according to the invention has a fastening device for one end of a second mounting rail, which is referred to here as the "mating" mounting rail, which is arranged transversely or obliquely to the first, here referred to as the "mating" mounting rail, and a hook-like fastening element for fastening the angle connector at the mating mounting rail. For fastening, the hook-shaped fastening elements of the angle connector are hooked on the side of the mating mounting rail opposite the fastening means of the angle connector and hold the angle connector on the mating mounting rail by form-locking with the mating mounting rail. The hook-shaped fastening element of the angle connector according to the invention overlaps the mating mounting rail from the longitudinal side, on which the fastening device of the angle connector is located, toward the opposite side of the mating mounting rail, at which the hook-shaped fastening element hangs, when the angle connector is fastened as intended at the mating mounting rail and the hook-shaped fastening element hangs at the side of the mating mounting rail opposite the fastening device for the end of the mating mounting rail. The docked and docked mounting rails are preferably arranged in one plane, but can also have a height offset, i.e. lie in different planes.
According to the invention, the hook-shaped fastening element is S-or Z-shaped, so that it can engage with the bottom at an undercut on the opposite side of the mating mounting rail from the fastening device, when the hook-shaped fastening element hangs as intended at the opposite side of the mating mounting rail. "opposite" does not necessarily mean opposite longitudinal sides of the docked mounting rail, but for example also means that the through-going longitudinal groove of the docked mounting rail is remote from the edge of the fastening means of the angle connector. The "opposing" is in particular the half of the fastening means of the docked mounting rail facing away from the angle connector. The hook-shaped fastening elements can engage, for example, the bottom of the edge of the hole as an undercut in the mounting rail.
One configuration of the angle connector according to the invention provides for the docked mounting rail to have a through-going longitudinal groove which extends in the longitudinal direction of the docked mounting rail and thus transversely to the docked mounting rail. The edges of the longitudinal groove are bent inwards into the abutting mounting rail and form an undercut. The hook-like fastening element is S-or Z-shaped such that its base engages one of the inwardly bent edges when the angle connector, as specified, hangs up at the abutting mounting rail. In particular, the docked mounting rail has two inwardly bent edges at both sides of the longitudinal slot, wherein the hook-shaped fastening element bottom engages the edge facing away from the mounting rail to be docked.
One embodiment of the invention provides that the angle connector has an abutment for the longitudinal side of the mating mounting rail. The abutment can be, for example, a flat plate which abuts externally against the longitudinal side of the docked mounting rail when the angle connector, as specified, is hung from and fastened to the docked mounting rail. Hook-shaped fastening elements project from the side of the abutment for the docked mounting rail opposite the fastening means for the end of the docked mounting rail. The hook-shaped fastening element projecting from the abutment on the fastening device at the end of the mounting rail for docking is thus arranged relative to the fastening device at the abutment for the longitudinal side of the docked mounting rail.
One configuration of the invention provides for the abutment of the angle connector to be used on the longitudinal side of the mating mounting rail. In particular, the hook-shaped fastening element projects obliquely at an acute angle from the abutment. In particular, the abutment is flat and the hook-shaped fastening element projects obliquely at an acute angle to this plane.
In particular, the fastening element is arranged at a first end of the abutment and is bent in an S or Z shape such that a free end of the fastening element points away from a second end of the abutment, which is opposite the first end of the abutment.
The hook-shaped fastening elements are preferably integral components of the angle connector according to the invention. For example, the angle connector with its hook-shaped fastening element is produced in one piece from a sheet metal material by bending and/or bending.
One configuration of the invention provides a U-shaped bracket as a fastening means for the end of the butted mounting rails, into which bracket the end of the butted mounting rails can be inserted. A bracket can also be understood as a profile. The hook-shaped fastening elements are in particular longer than half the clear width of the U-shaped bracket. The term "width" here means the distance between the inner sides of the legs of the U-shaped support facing each other. "Length" relates in particular to the distance of the free end of the hook-shaped fastening element from the abutment of the angle connector.
In one embodiment of the invention, the hook-shaped fastening elements of the angle connectors have serrations, meshes, serrations or the like at the free ends, which may be molded into the mating mounting rail or engage in complementary serrations, meshes, serrations or the like at the mounting rail, and/or which improve the force-locking and/or form-locking, in particular in the longitudinal direction of the mating mounting rail, at which the hook-shaped fastening elements are or are to be hooked.
One preferred configuration of the present invention provides threaded holes (i.e., through holes for penetrating fasteners such as screws, bolts, etc.) to secure the angle connectors at the mating mounting rails. The threaded bore is in particular in a bend arranged at the abutment, which bend is arranged at the second end of the abutment. The spacing of the hook-shaped fastening element from the bent-over portion corresponds substantially to the height of the abutting mounting rail. The threaded bores of the angle connectors are in particular located on the side of the angle connectors opposite the mating mounting rail, as are the hook-shaped fastening elements, when the angle connectors are arranged as intended on the mating mounting rail.
The assembly according to the invention provides two mounting rails, from which one end of the butted mounting rail is fastened at its longitudinal side by means of an angle connector of the aforementioned kind.
In one embodiment of the assembly according to the invention, the angle connector has an abutment which abuts externally against the one longitudinal side of the mating mounting rail. The hook-shaped fastening elements of the angle connectors overlap the mating mounting rail transversely to the contact point of the angle connectors and engage in the openings of the mating mounting rail. Such as a hole or a longitudinal slot in the butted mounting rail. The hook-shaped fastening element can overlap the abutting mounting rail above, below or laterally. At the side of the abutment remote from the angle connector, for example at the edge of the bore or longitudinal groove remote from the abutment, the mounting rail to which it is butted has an undercut. The side of the abutment remote from the angle connector can also be understood as the side of the docked mounting rail opposite the fastening means of the abutment or of the end of the mounting rail for docking. The undercut can be formed, for example, by an inwardly projecting flange of a longitudinal groove of the mounting rail, which surrounds the hole, or an edge which is bent inwards into the mounting rail. The hook-shaped fastening elements of the angle connector according to the invention engage with their bottoms in the interior of the mating mounting rail, where the angle connector is fastened. The hook-shaped fastening elements of the angle connector engage with their bottoms in undercuts on the side opposite the abutments and hold the abutments of the angle connector by form-locking at the longitudinal side of the mating mounting rail. The hook-shaped fastening element does not necessarily have to hold the abutment of the angle connector forcibly against the longitudinal side of the mating mounting rail, but rather, owing to the gap, an intermediate space can be created between the abutment of the angle connector and the longitudinal side of the mating mounting rail.
According to one embodiment of the assembly according to the invention, the angled connector is provided with a bent-over portion with a threaded bore, so that the angled connector can be fastened with a fastening element at the abutting mounting rail. Fastening can be achieved, for example, by screwing the angle connector with the docked mounting rail by means of a T-head screw or a rectangular nut. Fastening (which can also be referred to as fixing) the hook-shaped fastening elements of the tightening angle connector to the mating mounting rail or, in any case, preventing the hook-shaped fastening elements from being able to become detached from the mounting rail. This ensures that the abutments of the angle connectors remain at the longitudinal sides of the docked mounting rail and that the docked mounting rail is not tilted when loaded with the docked mounting rail fastened thereto transversely or obliquely with the angle connectors, i.e. the docked mounting rail does not swing about its longitudinal axis when loaded with the docked mounting rail. By the hook-shaped fastening elements of the angle connectors according to the invention hanging at the mating mounting rail and the angle connectors being fixed at the opposite sides of the mating mounting rail, the connection is more stable than without being fixed at the opposite sides, since twisting of the mating mounting rail is avoided. The opposite side of the mating mounting rail, at which the hook-shaped fastening element of the angle connector is suspended and to which the angle connector is fixed, is in particular different from the opposite side at which the fastening device for the end of the mating mounting rail is arranged and at which the hook-shaped fastening element is suspended.

Detailed Description
The angle connector 1 according to the invention shown in fig. 1 is made of sheet steel and has a clip 2 which is C-shaped in side view and a bracket 3 which is U-shaped in cross section and which can also be understood as a fastening device 4 for the ends of an undepicted mounting rail, which is also referred to below as a butt-joint mounting rail.
The C-clip 2 is bent from a steel strip of constant width and has a flat central piece 5 which forms an abutment 6 for abutment at a longitudinal side of a mounting rail 7, which is also referred to below as the butted mounting rail. At the end of the center piece 5, the C-clip 2 has a right-angled bend 8 with a through-hole as a threaded hole 9.
At the end opposite the fold 8, the center piece 5 of the C-clip 2 of the angle connector 1 according to the invention has a hook-shaped fastening element 10, which, viewed transversely to the C-clip 2 (i.e. viewed in the longitudinal direction of the C-shaped contour of the clip 2), can be understood as being S-or Z-shaped. The hook-shaped fastening element 10 projects from the central part 5 of the C-clip 2, which forms the abutment 6, on the same side as the fold 8. The hook-shaped fastening element 10 first projects at right angles from the flat central part 5 of the C-clip 2 by a small piece, then extends at a slight incline away from the abutment 6 in the direction toward the fold 8 and, at the end, is bent, viewed from the side, into a hook 11 which points away from the fold 6. In the central part of the hook-shaped fastening element 10, which extends at an acute angle relative to the central part 5 of the C-clip 2 of the angle connector 1 according to the invention, which forms the abutment 6, the hook-shaped fastening element 10 extends away from the abutment 6 in a direction slightly inclined toward the fold 8.
The free end edge of the hook 11 of the hook-shaped fastening element 10 of the angle connector 1 facing away from the fold 8 is serrated, i.e. the end edge of the hook 11 has serrations 12, which can be seen in fig. 2.
A U-shaped bracket 3 projects at right angles from the central part 5 and, like the fold 8 and the hook-shaped fastening element 10, on the opposite side, the U-shaped bracket 3 forming a fastening device 4 for the end of a second, mating mounting rail, not shown. In this embodiment, the U-shaped bracket 3 is a steel profile which is welded to the center piece 5 of the C-clamp 2. The U-shaped bracket 3 is open on the side where the fold 8 is located and is closed at the side where the opposite, hook-shaped fastening element 10 is located.
The angle connector 1 according to the invention can be produced and/or shaped differently from the described embodiments, it can be produced without bent and welded sheet metal and, moreover, does not have to be produced from metal.
As shown in fig. 3, in order to secure the angle connector 1 transversely at the longitudinal side 13 of the docked first mounting rail 7, the angle connector 1 is fitted from one side at the longitudinal side 13 of the docked mounting rail 7. In the depicted embodiment of the invention, the abutting mounting rail 7 is a double mounting rail, which consists of two identical mounting rails, which are welded to each other with their bottom sides abutting each other. The welded mounting rails each have a through-going longitudinal groove 14 in the longitudinal center plane of the mounting rail 7, wherein the longitudinal grooves 14 are located in opposite sides of the double mounting rail. The edges 15 of the longitudinal groove 14 are bent inwards into the mounting rail 7 and form an undercut 16 at the mounting rail 7 or in the mounting rail 7.
In this embodiment the mounting rail 7 to be docked extends horizontally and its longitudinal slots 14 are above and below. Other orientations of the docked mounting rail 7 are also possible.
For fastening at the longitudinal side 13 of the docked mounting rail 7, as is depicted in fig. 3, the angle connector 1 according to the invention is fitted obliquely at the longitudinal side 13 of the docked mounting rail 7 such that its hook-shaped fastening element 10 enters into one longitudinal groove 14 of the mounting rail 7 and the longitudinal edge of the mounting rail 7 in the inner corner of the C-clip 2 of the angle connector 2 is placed at the transition from the flat center piece 5 forming the abutment 6 to the hook-shaped fastening element 10 of the C-clip 2 of the angle connector 1. Subsequently, the angle connector 1 is turned around the longitudinal side of the mounting rail 7 in such a way that the center piece 5 of the C-clip 2 of the angle connector 1, which center piece forms the abutment 6, comes into abutment with the longitudinal side 13 of the mounting rail 7, as is shown in fig. 4. The fold 8 now overlaps one of the two sides of the abutting mounting rail 7 with the longitudinal slot 14, and the threaded hole 9 is in the center of one of the two longitudinal slots 14 of the mounting rail 7. The hook-shaped fastening element 10 and the fold 8 of the angle connector 1 overlap the abutting mounting rail 7 at the opposite longitudinal side. The abutment 6 of the angle connector 1 is located on the longitudinal side 13 of the adjoining mounting rail 7, which connects the overlapping hook-shaped fastening element 10 to the two longitudinal sides of the fold 8.
By turning the angle connector 1 with the center piece 5 forming the abutment 6 over to the longitudinal side 13 of the mating mounting rail 7, the hook 11 at the end of the hook-shaped fastening element 10, viewed from the abutment 6 of the angle connector 1, reaches behind the edge 15 of the longitudinal groove 13 on the side of the mounting rail 7 opposite the fold 8, which is bent inward into the mounting rail 7, so that the bottom of the hook 11 engages the edge 15 of the longitudinal groove 13 of the mounting rail 7, which forms the undercut 16. By engaging the bottom with the edge 15 forming the undercut 16, the hook-shaped fastening element 10 holds the angle connector 1 against lateral pulling at the longitudinal side 13 of the mating mounting rail 7 by form-locking. The angle connector 1 cannot be pulled out laterally from the longitudinal side 13 of the mounting rail 7, wherein gaps can occur between the abutment 6 of the angle connector 1 and the longitudinal side 13 of the mounting rail 7 due to play and/or tolerances, when the angle connector 1 is pulled transversely to the mounting rail 7.
The oblique fitting of the angle connector 1 at the longitudinal side 13 of the mating mounting rail 7 and the tilting of the angle connector 1, such that its abutment 6 comes into abutment with the longitudinal side 13 of the mounting rail 7 and the bottom of the hook 11 of the hook-shaped fastening element 10 engages with an edge 15, which is bent inward into the mounting rail 7 and forms an undercut 16, can also be understood as the hook-shaped fastening element 10 hanging at or in the mounting rail 7. The hook-shaped fastening element 10 of the angle connector 1 according to the invention is hooked on the center piece 5 forming the abutment 6 and on the edge 15 of the longitudinal groove 16 in the mounting rail 7 remote from the U-shaped bracket 3, which can also be understood as the side of the mounting rail 7 opposite the longitudinal side 13 of the angle connector 1 or of the mounting rail 7 at which the angle connector 1 is fastened or fastened.
For the connection with the docked mounting rail 7, the not drawn, docked mounting rail enters the U-shaped bracket 3, which forms the fastening device 4 of the angle connector 1. The ends of the abutting mounting rails can be screwed and/or hooked, for example, to the U-shaped bracket 3. The butted and the butted mounting rail 7 are in one plane, however can also have an offset with respect to each other. In this embodiment the docked mounting rail is arranged transversely to the docked mounting rail 7, however an arrangement with the docked mounting rail inclined to the docked mounting rail 7 is also possible. The butted mounting rail can have a different cross section than the butted mounting rail 7, which can be in particular a single mounting rail having a longitudinal slot at one longitudinal side and a hole in the transverse center of the opposite longitudinal side. The mounting rail 7 to be docked does not have to be a double mounting rail 7, but can be a single mounting rail (not shown). In the depicted embodiment the butted mounting rail and the butted mounting rail 7 are of the same width and as wide as the inner width (or clear width) of the U-shaped bracket 3 forming the fastening means 4 for the ends of the butted mounting rails. The hook-like fastening elements 10 of the angle connector 1 according to the invention are longer than half the width of the mating mounting rail and/or half the width of the mating mounting rail 7 and/or than half the inner width or half the clear width of the U-shaped bracket 3.
When the hook-shaped fastening element 10 is suspended in the mating mounting rail 7 by turning the angle connector 1 with its abutment 6 from the outside onto the longitudinal side 13 of the mounting rail 7, the serrations 12 at the end edges of the hook-shaped fastening element 10 enter from the inside into abutment with the mounting rail 7 and, if necessary, are molded into the mounting rail 7. This increases the friction and, if necessary, forms a form-lock which makes it difficult for the angle connector 1 to move in the longitudinal direction of the mounting rail 7.
The angle connector 1 is fixed, i.e. fastened, at the mounting rail 7 by means of a rectangular nut 17, which is held on the side of the fold 8 in the mounting rail 7 and is placed transversely in the mounting rail 7 by means of a holder 18, and by means of a screw as a fastener 19, which is introduced into the rectangular nut 17 through a threaded hole 9 in the fold 7 of the angle connector 1 and is screwed. Furthermore, the fastening element 19 and the rectangular nut 17 tighten the fold 8 from the outside against the mounting rail 7 and the hook 11 of the hook-shaped fastening element 10 from the inside against the mounting rail 7 on the opposite side of the mounting rail 7. The serrations 12 at the end edges of the hook-shaped fastening elements 10 are thereby molded into the mounting rail 7 from the inside, if necessary, increasing the resistance of the angle connector 1 to movement in the longitudinal direction of the mating mounting rail 7.
In fig. 5 and 6, the angle connector 1 according to the invention with its hook-shaped fastening element 10 is merely hooked into the longitudinal groove 14 of the mating mounting rail 7 at the top, so that the abutment 6 of the angle connector 1 abuts on the outside at the longitudinal side 13 of the mounting rail 7. The hooking is effected as described above with reference to fig. 3 and 4, wherein in fig. 5 and 6 the angle connector 1 is oriented in the opposite direction such that the hook-shaped fastening element 10 is located above, but not below. It is sufficient to fasten the angle connector 1 at the longitudinal side 13 of the mating mounting rail 7 by hooking the hook-shaped fastening elements 10 of the angle connector internally at the opposite side of the mounting rail 7, an additional screw connection on the opposite longitudinal side of the mounting rail 7 (i.e. the longitudinal side lying below in fig. 6) is also possible, as is shown in fig. 4 (there, however above), but not necessary. The fold 8 with the threaded bore 9 can be omitted, as long as no screw connection of the angle connector 1 to the mounting rail 7 is provided. Thus, the angled connector 1 is depicted in fig. 5 and 6 without the fold 8. For the description of fig. 5 and 6, reference is additionally made to the description of fig. 1 to 4. Like elements are denoted by like reference numerals throughout the drawings.
One abutting mounting rail forms an assembly of two abutting mounting rails 7 according to the invention, which are arranged transversely or obliquely to one another (i.e. not extending from one another), the ends of which are fastened as drawn at the longitudinal sides 13 of the abutting mounting rails 7 with the angle connectors 1 according to the invention.
