Description

The invention relates to an arrangement for fastening a rail.

Such arrangements are known from the prior art and are used, for example, in dry construction. Attaching a rail to a fixed structure, such as a ceiling or a wall, usually serves to suspend a ceiling or to wall a wall in order to secure the cover elements required therefor to the rail.

For fixing the rail to the fixed structure, different elements are known from the prior art. Such an element is a spacer, which can also be referred to as a direct hanger. Such a spacer element comprises a base region with which the spacer element can be fixed to the fixed structure. Furthermore, the spacer element comprises two spacer strips arranged on opposite sides of the base region. These spacer strips can either be designed to be stretched, so that they are flush with the base area, which is generally flat, or else they are angled, so that the spacer strips are arranged perpendicular to the base area. To fasten the rail to the fixed structure, the spacer element is first fixed to the fixed structure and then the rail is fixed to the spacer strips of the spacer at a defined distance from the fixed structure.

Another element for securing a rail to a fixed structure is also known in the art and may also be referred to as a direct hanger become. Such as hereinafter referred to as clamping device element comprises a base plate which engages over an open side of the rail. The clamping device further comprises hook elements to fix them to the rail. For fixing the rail to the fixed structure, the clamping device is first clamped to the rail and then fixed to the fixed structure. However, it is also customary to first fix the clamping device to the fixed structure and to clamp the rail only in the subsequent step. Depending on the length of the rail and weight of the top members, the number of spacers and / or clamps per rail will vary, however, at least two such members are necessary for securing the rail to the fixed structure.

Both elements for attaching a rail to a fixed structure may be mutually supplementary used in attaching a rail to a fixed structure.

However, previously known elements or previously known arrangements for attaching a rail to a fixed structure are problematic in terms of their adjustability and their handling during assembly.

In the sense of a high-quality fastened rail or multiple rails, it is necessary that they are all aligned in a defined position to each other. In most cases, it is desirable that they are arranged on the solid structure so that subsequently mounted top elements can form a flat surface and unsightly bulges are avoided. Such alignment of the rails to each other is difficult and very power-consuming to produce in oblique ceilings or vaulted ceiling gradients for the person to be assembled or the persons to be assembled. So far, it is usual for fastening and / or horizontal alignment and producing a mounting position of a rail, for example on a ceiling, that a person or a fitter by means of a measuring device such as a centimeter measure the distance between the rail and the ceiling or the floor and the rail holds so that the second mechanic can fix the rail to the spacer. To date, at least two fitters have always been necessary for such an adjustment.

The invention is therefore based on the object to provide an arrangement for fastening a rail, which overcomes the disadvantages of the prior art, in particular by the fact that the arrangement with respect to the adjustability and handling comprises optimized elements.

This object is achieved by the arrangement for fastening a rail with the features of claim 1.

According to the invention, therefore, an arrangement for fastening a rail is proposed, which has two side walls and a bottom and is designed substantially as a C-profile, on a fixed structure, comprising a spacer, which has a base area and two on opposite sides of the base area and perpendicular to this arranged spacer strips, which are aligned parallel to the side walls of the rail, and a clamping device, comprising a base plate which engages over an open side of the rail, and at least two hook elements, so that the clamping device with the rail can be hooked. The arrangement according to the invention for fastening a rail is characterized in that a fixing element is arranged on opposite sides of the base plate of the clamping device, which in each case comprises at least one resilient fixing tongue with a strip side facing the spacer strip and an outer side facing away from the strip side in that, in a mounting position, it acts on one of the spacer strips of the spacer element by means of a pretension so that the clamping device is fixed to the spacer element.

By means of the arrangement according to the invention, it is possible for a single fitter to adjust the rail in a simple manner and without the aid of a second fitter and fasten it to the fixed structure. This is achieved in that the resilient fixing tongue acts on the spacer bar, that the previously clamped with the clamping device rail is held by this fixation.

To fasten the rail to a fixed structure, the spacer element is first of all fixed to the solid structure. The two spacer strips of the spacer are aligned perpendicular to the fixed structure. In the clamping device, the rail is clamped. The fitter grasps the rail and the clamping device jammed with the rail and guides it to the spacer fixed to the fixed structure. The installer spends the rail in the space between the two spacer strips of the spacer element, so that the at least two fixing tongues act on one of the two spacer strips and thus fix the clamping device and the rail jammed on the clamping device to the spacer element. As a result, a secured position is set, in which the installer can release the rail, because the spring force of the fixing tongues is so large that it fixes the rail in the secured position. In the secured position, the fitter can adjust the rail along the spacer strips of the clamping device and thereby produce a horizontally arranged rail or at least a uniform rail distribution on a ceiling or defined rail courses and their orientation defined each other. If the rail is fixed, the installer can then connect the rail as previously known manner. This connection is usually made by screwing.

In a preferred embodiment of the arrangement for securing a rail according to the invention, each of the two fixing elements comprises a back plate which is arranged substantially perpendicular to the base plate of the clamping device, two side plates arranged on two opposite sides of the back plate, which are substantially perpendicular to the back plate and the Are arranged facing away from the base plate, and two on one of the two side plates arranged end plates, which are arranged substantially parallel to the back plate and extending towards each other. By this embodiment of the fixing a Fixierlasche is formed, which is advantageous in fixing the clamping device to the spacer. The spacer strips of the spacer element can be easily threaded into the formed tab of the fixing element. In this tab, the spacer bar of the spacer is also guided. The guiding is therefore advantageous because an inadvertent abutment on the rail perpendicular to the course of the spacer strips after threading preserves the adjustment. Between the two to each other extending end plates of a fixing element, a gap is provided which is so large that it can be penetrated by a screw or a screw head. Such a distance is advantageous because an inserted screw leaves the two end plates and thus the fixing tongues unimpaired. The fixing elements can thereby retain the formed tab shape, so that after loosening the screw during a conceivable dismantling of the rail, the rail remains fixed by the fixing tongues.

In a further preferred embodiment of the arrangement for fastening a rail according to the invention, at least one of the two fixing elements for one of the two spacer strips at least one guide means which guides the at least one spacer bar during the interaction with the at least one fixing element. A guide facilitates the work of the mechanic to a considerable extent, since it directs the fixing element or the rail in a desired position, thereby preventing jamming of the rail with the fixing. If the fixing element is designed as a tab, it is conceivable, for example, to design the guide as a guide tongue which is partially punched out of the side plates. Such a guide tongue prevents tilting of one of the spacer strips in a fixing element designed as a tab. If such a guide tongue is executed in each of the two side plates, the fixing element is centered independently with respect to the corresponding spacer strip.

In a further preferred embodiment of the arrangement for fastening a rail according to the invention, at least one fixing head is arranged on the strip side of the fixing tongue. Such a fixing head can be designed, for example, as a soldering point or as a welded point. However, it is also conceivable to produce such a head by means of a corresponding forming process. Such a head is advantageous because it can engage in recesses of the spacer. Such recesses may be, for example, holes in commercially available spacers. Through the head and the interaction with one of the recesses, it is possible to provide a step-dependent arrangement available. By the head, which engages in a recess, it is also possible, a relatively stable Establish fixation between the fixing of the clamping device and the spacer bar of the spacer.

In a further preferred embodiment of the arrangement for fastening a rail according to the invention, at least one fixing catch and / or at least one fixing tooth is arranged on the strip side of the fixing tongue. Such a Fixierraste may for example be designed as a folded free end of the fixing, which extends in the direction of the spacer. It is also conceivable from the fixing partially punched out Fixierraste. A fixing tooth can for example be formed by means of forming from the fixing itself or fixedly attached to this. It is conceivable that the at least one fixing catch and / or the at least one fixing tooth extends transversely to a longitudinal course of the fixing tongue over the entire width of the fixing tongue. However, it is also conceivable to carry out the at least one fixing catch and / or the at least one fixing tooth shorter. By means of the at least one fixing catch and / or the at least one fixing tooth and the interaction with a correspondingly designed spacer strip, it is possible to provide a step-dependent arrangement. In addition, it is possible to produce a relatively stable fixation between the fixing element of the clamping device and the spacer strip of the spacer element.

In a further preferred embodiment of the arrangement for fastening a rail according to the invention, a release projection is arranged on the fixing tongue, so that the fixing tongue can be manipulated against its bias. Such a release projection allows the removal of the fixation between the fixing tongue and the spacer bar of the spacer. If a fixing head, a fixing catch or a fixing tooth is provided on the fixing tongue, it is advantageously possible by means of the release projection to dissolve the engagement produced by one of the three elements. If the fixing tongue is executed without one of the three elements, it is possible by means of the release projection to manipulate the fixing tongue counter to its pretension in such a way that the friction between the fixing tongue and the spacer strip is reduced or eliminated.

In a further preferred embodiment of the arrangement for fastening a rail according to the invention, at least one of the two fixing elements comprises more than one fixing tongue, in order to allow a firmer fixing in contrast to the arrangement of one and to reduce the possibility of jamming during the production of the assembly position.

In a further preferred embodiment of the arrangement for fastening a rail according to the invention, the spacer element on at least one spacer bar on at least one fixing recess, which corresponds to the at least one fixing head. Such a Fixierausnehmung can be performed by the spacer bar thorough or not by cross. An advantage of such a Fixierausnehmungen is the secure locking of the fixing head with the spacer bar of the spacer and the reduced weight of the spacer.

In a further preferred embodiment of the arrangement for fastening a rail according to the invention, the spacer element on at least one spacer bar on at least one sawtooth-like profile strip, which corresponds to the at least one Fixierraste and / or at least one fixing tooth. An advantage of such a sawtooth-like profile strip is the secure locking of the at least one Fixierraste and / or the at least one fixing tooth with the spacer bar of the spacer element.

Further advantages and advantageous embodiments of the subject matter of the invention are the description, the drawings and the claims removed.

FIG. 1 shows an arrangement for securing a rail 2 to a fixed structure, not shown. The solid structure may be, for example, a ceiling or a wall of a room in a building. The arrangement comprises a spacer element 10 and a clamping device 30.

The rail 2 is designed as a commercially available C-profile rail (CD 60/27). The rail 2 has two side walls 4, which are aligned parallel to each other and arranged perpendicular to a bottom 6. Both side walls 4 have at their edge facing away from the bottom 6 in each case one extending in the longitudinal direction of the rail 2 kinking.

The clamping device 30 comprises a base plate 32 which engages over an open side of the rail 2. At the the open side of the rail 2 cross-edges of the base plate 32 is disposed on both sides of a vertical longitudinal center plane of the rail 2, depending on a fixing element 50. Each of the two fixing elements 50 has a back plate 54, such as FIG. 2 shows. The back plate 54 is arranged perpendicular to the base plate 32 and is thus aligned in a mounting position parallel to the side wall 4 of the rail 2. At the lying in the longitudinal direction of the rail 2 edges of the back plate 54 each have a side plate 56 is arranged. The side plates 56 are aligned substantially perpendicular to the back plate 54 and are facing away from the rail 2. On each of the two side plates 56 a respective end plate 58 is arranged, which is arranged substantially parallel to the back plate 54. The two end plates 58 of a fixing element 50 extend towards each other, so that a tab is formed by said arrangement of the back plate 54, the two side plates 56 and the two end plates 58.

Each of the end plates 58 includes a fixing tongue 52. The fixing tongue 52 is integral with the end plate 58 and partially punched out of this. The fixing tongue 52 is the base plate side fixedly connected to the end plate 58 and provided with a bias in the direction of the back plate 54.

The back plate 54 has serially arranged holes, which allow a passage of a screw and the screwing of the clamping device 30 with the rail 2. At both transverse to the vertical longitudinal center plane of the rail 2 edges of the base plate 32 hook elements 34 are formed. These hook elements 34 engage with the bends of the side walls 4 of the rail 2 and thus fix the clamping device 30 to the rail 2.

The spacer element 10 of the arrangement comprises a base region 12 on which spacer strips 14 are arranged on both sides of the vertical longitudinal center plane of the rail 2. The spacer strips 14 are aligned in the mounted state perpendicular to the base region 12 and thus extend parallel to the side walls 4 of the rail 2. The spacer strips 14 pass through the tabs formed by the fixing elements 50. The spacer strips 14 each have two profile strips 18 on their sides facing the fixing tongues 52. The profiled strips 18 are designed sawtooth-like and correspond to the respective fixing tongue 52 and the fixing teeth arranged thereon. The spacer strips 14 have in their longitudinal direction in rows arranged holes, which allow the passage of a screw and the screwing of the spacer 10 with the clamping device 30 and the rail 2.

FIG. 3 shows a detailed view of a fixing element 50 according to the invention. In each of the two side plates 56 of the fixing element 50, a guide device 60 is arranged. The guide device 60 is in each case formed integrally with the corresponding side plate 56. The guide means 60 has a tongue-like shape which is bent over its length in the direction of the tab formed by the back plate 54, the side plates 56 and the end plate 58. The illustrated fixing element 50 has no holes for screws, so that it is possible to use thread-cutting screws in a meaningful way.

The FIGS. 4 to 8 show different embodiments of the fixing tongue 52 in a schematic view from a perspective direction of the tab formed. In the FIG. 4 The illustrated fixing tongue 52 protrudes into the tab and has a friction surface 70 on its side facing the back plate 54. If the tab of the fixing element 50 is penetrated by the spacer strip 14, the fixing tongue 52 rests with its friction surface 70 against the spacer strip 14. This concern is caused by the introduced into the fixing tongue 52 bias. The bias introduced in this embodiment is sufficient to fix the clamping device 30 and a clamped or screwed to the clamping device 30 rail 2.

In the FIG. 5 The illustrated fixing tongue 52 has a fixing head 62 in the region of its free end. The fixing head 62 is arranged facing the back plate 54. For fixing the clamping device 30 to the spacer 10 of the fixing head 62 engages in one of FIG. 10 pictured Fixierausnehmungen 16 a. The fixing tongue 52, which in FIG. 6 is shown, has at its free end a kinking, which is designed as a fixing peg 64. The Fixierraste 64 is arranged largely perpendicular to the surface of the fixing tongue 52 and projects in the direction of the back plate 54. To fix the clamping device 30 to the spacer 10, the fixing tongue 64 engages in the profile strip 18 of the spacer bar 14, which in FIG. 9 is shown. The fixing tongue 62, which in FIG. 7 is shown, has a curved shape mainly in the direction of the back plate 54 and a friction surface 70 on. While the fixing tongue 52 extends in its upper region in the direction of the back plate 54, its lower region of the back plate 54 extends away. At the outer end or at the end of the lower region of the fixing tongue 52, a bend is arranged, which is designed as a release projection 66. This release projection 66 is arranged largely perpendicular to the region of its arrangement on the surface of the fixing tongue 52 and the back plate 54 faces away. The release projection 66 protrudes through a recess formed by the partial punching of the fixing tongue. The in the FIG. 8 shown fixing tongue 52 has two fixing teeth 68, which extend in the direction of the back plate 54 and are arranged transversely to the Fixierzungenverlauf. To fix the clamping device 30 to the spacer 10, the fixing teeth 68 engage in the corresponding profiled strip 18 of the spacer bar 14.

The FIGS. 9 and 10 show two embodiments of a spacer 10 according to the invention. The base portion 12 has two recesses with which the spacer 10 can be fixed to the fixed structure. The spacer strips 14 of in FIG. 9 shown spacer 10 have two extending in the longitudinal direction of the spacer bar 14 profile strips 18. The profile strips 18 are serrated transversely to the longitudinal course and can correspond to the corresponding fixing tongue 52 of the fixing element 50. The spacer 10 off FIG. 10 has Fixierausnehmungen 16 in its spacer bars 14 on the fixing recesses 16 are arranged on both sides of row-like arranged boreholes parallel to these and can correspond to the corresponding fixing tongue 52 and the corresponding fixing head 62 on the fixing tongue 52.
