Description

The invention relates to a bracket clamp for mounting of pipes or cables, with multiple pipes or cables are arranged axially parallel to one another, consisting of a trough-shaped, approximately U-shaped ge curved bracket, which is a tube or Cable underneath comprehensively and / or supporting one Building ceiling, a rail or a profile angle be is fixable, with several brackets to form axially parallel, one above the other Cable or pipe receptacles can be plugged on top of each other and can be locked in the stack position thus formed.

From DE 38 18 362 A1 a clamp is generic known in accordance with which the bracket made of channel profiles can be put together. It can be seen that the channel profiles can be plugged on top of each other,  because on the one hand in the base of the channel profile Receiving groove and on the other hand at the leg ends of the Channel profile opposing locking lugs are arranged. However, pushing one another on Channel profiles with their thighs excluded. In addition, there is no with these channel profiles Tolerance compensation possible because there is only one fixed Rest position there. In addition, this training is insofar disadvantageous, as mutually transverse channels (cable receiving channel or receiving channel for the additional Fastening element and groove in the base) have to be asked, which inevitably leads to ferti technical disadvantages. Finally is assembly is also time-consuming because it is tailored to each corresponding pipe or cable diameter Channel profiles, which are also to be manufactured separately, selected from the range and combined with each other must be renated.

Based on this state of the art, the Er the task is based on a clamp  Generic type to create that simple Manufacturing allows a particularly simple assembly.

To solve this problem is for the generic clamp suggested that the brackets with their legs on which in a Direction across to the female recorders Distance from each other locking lugs and locking receptacles are arranged, can be pushed onto each other.

The training according to the invention enables him Significant tolerance compensation, because the one on the other her thighs slidable gutter-shaped temples according to the inserted pipe or cable diameter knives can be pushed onto a passport. It can So identical channel profiles for the production of the Strap clamps are used, which at the same time the Assembly effort reduced.

In addition, the manufacture of these gutter-shaped brackets simplified because the arrangement of the detents and rest recordings on the thighs to an uncomplicated Manufacturing leads.

From DE-PS 9 32 190 is a channel profile be knows, in each case two, but different Lich trained channel profiles with their legs can be pushed onto one another in opposite directions and also the locking receptacles or the locking lugs on the Legs are arranged, however, these are locking means not seen in the longitudinal extension of the legs with Ab stood apart from each other, but they are in arranged at the same height.

The channel profiles according to the invention can be made of sheet metal bent or made of plastic. To the place fixed mounting can be the topmost in the installation position Channel profile, which forms the bracket, ent have speaking recesses to get into a profile rail or the like can be inserted. The gutters in the installation position below shaped brackets are located on top of each Lichen-shaped bracket slidable and in the Lockable target position. This arrangement enables for example in the top gutter-shaped bracket  first insert a cable or pipe and this top gutter-shaped bracket stationary, for example to be attached to a C-profile rail. Below can then another cable or pipe into another gutter-shaped bracket can be inserted, which with its Thighs on the legs of the first bracket can be pushed and locked.

If several cables or pipes are to be held, the desired number of tubes or number of cables is thus speaking the desired number of stirrups one on top of the other stackable. This training is advantageous for assembly adherent, since not all ver parallel to each other ver placed pipes or cables in a bracket must and then the bracket must be attached, but each individual pipe or cable can be in a separate one gutter-shaped bracket arranged and on the in the one position above the bracket are attached. The arrangement of the catches and snap-in receptacles is used for Securing the stack position. Only the one in the installation top bracket is with hook or similar Be Fastening elements provided on a profile rail  or can be attached to a profile iron. The in the Installation position below the gutter-shaped bracket are each formed identically, with the on push the bracket (across the axis) the ent intervene in the latching recesses can, so that the stack position is secured.

To prevent the superimposed ones channel-shaped bracket axially ver relative to each other can slide, it is provided that on the legs the bracket transverse to the longitudinal axis of the gutter and parallel to the legs extending, the axial Ver sliding of the stirrups to each other blows are arranged.

These stops can be made at the edge and / or strip-like projections or Recesses or the like can be formed there on the one hand, allow the brackets to run across the axis tion to push each other, the webs and off  form introductory aids, also in the introduction build a relative axial displacement of the bracket the web parts and recess is prevented.

Furthermore, it is preferably provided that in assembly position top bracket fixed attachment are arranged in the middle.

It is further preferred that the fixed attachable Fasteners by a between the legs of the top bracket attachable head piece formed are.

The head piece can be locked for the purpose of attachment be cash. It can be profiled so that it is connected to a C-profile rail, on profile iron or the like is hangable. It is also possible to use the headpiece to provide a screw passage opening so that the head piece directly on a building ceiling or the same is screw-fastened.

It is also preferably provided that the locking lugs on the or near the free leg ends of the bracket are arranged and the recesses on the base  protruding from the temple, parallel to the thighs extending and away from the thighs Approaches are trained.

With this training, it becomes a double channel shape formed, the upper one for inclusion in the installed position a cable or pipe is suitable, so that first this gutter-shaped bracket on the one above is snap-fit. The following in the installation position trough-shaped bracket can in turn be a cable or pipe record, with the locking leg of the upper bracket form a gutter shape at the head, which also at least partially includes the pipe or cable. The according to the base of the bracket is almost a double gutter formed, on the one hand in the installation lay leg up and on the other hand leg protrude below.

A preferred further development is seen in the fact that the locking lugs and recesses through axially parallel to Bracket-running serrations are formed, the Locking lugs on the inside of the legs  free leg ends are arranged and the rest recesses on the parallel to the legs extending approaches are formed.

This toothing can be designed as a single toothing, so that only one detent in a particular Target position is achievable. But it can also be used as a multi-tooth toothing be formed so that a larger rest area is available, the form-fitting Pinching cables or pipes of different Diameter allows.

It is also advantageous if the serrations behind are cut.

The undercut formation of the serrations is in front in part, especially in an apprenticeship where the weight of the inserted cables or pipes exerts tensile moment on the undercut toothing, so that due to the weight load the bracket increasingly are held in the closed position.  

A preferred development is also ge see that the headpiece is fixed in a fixed position bare C-profile rail can be inserted and one has rectangular locking approach, the Transverse extent in one direction smaller than the one guide gap of the C profile rail and in the 90 ° ge turned transverse extent larger than the insertion gap, but smaller than the clear width of the C profile rail is.

It can preferably be provided that the head piece on its face two with different Distance from the end face, essentially has rectangular locking lugs, a larger side of which is adjacent to the end face longer than the distant one.

All of the embodiments show clamps for holding pipes or cables, the pipes or cables not being drawn for reasons of clarity. The clamps are designed so that several pipes or cables can be arranged parallel to each other one above the other. In a first embodiment, which can be seen from Fig. 1, the bracket of the bracket clamp is formed by a channel profile 1 , on which further channel profiles 2 identical space shape can be pushed. The channel profiles 1 , 2 are U-shaped and have notches 3 , 4 on their legs, which protrude beyond the outer surface of the legs. As seen in the leg longitudinal direction 2, the trough sections at a distance from the notches 4 detent recesses 5, which cuts through From formed of the bar arms, addition are attached to the legs of the channel sections 1, 2 transversely to the channel longitudinal axis and parallel to the legs extending, the axial Movement of the channels profiles 1 , 2 stops 6 formed from each other. The stops 6 are formed in the exemplary embodiment according to FIG. 1 by the web parts that have been preserved between the recesses 5 . At these web parts the mutually facing edge of the engaging detents 3 , 4 put on, so that in the detent position, which is shown in FIG. 1, a secure fixation of the channel profiles 1 , 2 to one another is ensured.

The top channel profile 1 in the assembly position has cutouts 7 , which are used to fix the channel profile 1 to a C-profile rail. For this purpose, the channel profile can be inserted into a corresponding C-profile rail, the edge area of the C-profile delimiting the slot engaging in the slots 7 .

The embodiment according to FIG. 2 is essentially the same as the embodiment according to FIG. 1, but in the embodiment according to FIG. 1 the cable or tube inserted into the uppermost channel profile 1 is in the installed position on the C-profile rail or used to hold the clip supports a similar fixed built-in part. In the embodiment according to FIG. 2, the uppermost channel profile 1 is designed such that it can be snapped onto a corresponding cable or pipe. For this purpose, the base of the uppermost channel profile 1 is curved upwards in the installed position and, in the drawing, has a longitudinal slot below, into which a corresponding pipe or cable can be inserted. In this way, the uppermost pipe or cable in the installed position cannot be placed on the parts of the fixed attachment (for example a C-profile rail), but it bears against the rounded part 8 of the uppermost channel profile 1 .

While in the exemplary embodiments according to FIGS . 1 and 2, the channel profiles 1 , 2 can be formed, for example, from sheet metal, in the further embodiments an injection molded part is provided. In the embodiment according to FIGS. 3 to 5, the bracket is formed by identical channel profiles 9 , each of which can be pushed onto one another with its legs. Here, too, each channel profile 9 is U-shaped and has catches 10 and catch receptacles 11 on its legs. In addition, stops 12 , 13 are arranged on the legs, which extend transversely to the longitudinal axis of the channel and parallel to the legs and prevent the axial displacement of the channel profiles 9 from one another. The parts 12 are projecting webs, while the stop parts 13 are recesses running in the longitudinal direction of the legs, into which the webs 12 can be inserted. In this embodiment, the locking lugs 10 are arranged relatively on the inside at the free leg ends of the channel profile 9 , while the locking recesses projecting beyond the base 13 of the channel profile 9 , extending parallel to the legs and facing away from these approaches 14 . The base 13 is in the installation position both upward and downward ge rounded formed so that it can underlie or grasp a portion of an inserted tube or cable. The locking lugs 10 and locking recesses 11 are formed by axially parallel to the channel profile behind cut rows of teeth, which form an additional union clamping area for the cable or pipe to be clamped. For the purpose of fixed attachment of the bracket clamp formed from a plurality of channel profiles 9 , a head piece 15 or 16 is provided, which corresponds to de latching recesses 17 comparable to the latching recesses 11 of the channel profile 9 and also has sling means 12 in the form of webs, which also impact means in the forming grooves or recesses 13 of the uppermost channel profile 9 in the installed position can be inserted. The head piece has a gutter-shaped profile pointing toward the clamp 9 , so that an inserted cable or pipe is at least similar in shape.

Both head pieces 15 and 16 shown in the drawing can be inserted into a fixedly attachable profile rail 18 , 19 or 20 and have substantially rectangular or diamond-shaped locking latches 21 , 22 and 23 respectively. The transverse extent of the locking lugs 21 to 23 is in one direction smaller than the insertion gap of the associated C-profile rail 18 , 19 or 20 and in the 90 ° rotated transverse extension larger than the insertion gap, but smaller than the inside width of the associated C. - Profile rail 18 , 19 or 20 .

In the embodiment of FIGS. 9 through 11 of the locking lug 23 is formed by a so-called screw hammer head which is fixed to the base of the head piece 16. The head piece can be fastened to the associated C-profile rail 18 in such a way that it can be inserted into the gap of the C-profile rail 18 from below in the orientation shown in FIG. 11 and then by turning the head piece 16 by is transferred to the position shown in Fig. 10 90 °, in which the locking lugs engage over the ends of the legs of the C-profile rail 18. In this position, on the screw shaft of the locking screw 23 designed as a hammer head screw on screwed fastening nut 24 can be tightened so that the fixation on the C-profile rail 18 is ensured.

In the embodiment according to FIG. 6 to 8 are on the head piece 15, in particular at its end face, two different distances from said end face of ordered, substantially rectangular locking lugs 21, 22 are provided, of which the end face Benach barter (21) has a greater side length than the distant de ( 22 ).

This arrangement serves that the arrangement on a larger C-profile rail 20 by means of the locking approach 21 is possible, but also the attachment to a smaller C-profile rail 19 by means of the locking approach 22 is made possible. The locking approaches can be inserted into the slot of the corresponding C-profile rail 19 or 20 and secured in position by turning 90 °. For this purpose, in the embodiment, for example, integrally formed with the head piece 15 locking lugs 21 , 22 tightening surfaces 25 , so that a torque is exerted when twisting and a frictional clamping connection between the locking approach and the legs of the C-profile rail.

In the exemplary embodiment according to FIG. 12, the channel profile is designed similarly to the embodiment according to FIG. 3, although the channel profile 26 in the area of the recesses 11 is covered by cap-like molded parts 27 . The parts 27 have insertion openings 28 , into which the legs of an identical channel profile 26 located below can be inserted (from below), so that the locking projections 10 can engage in the locking recesses 11 . The lateral displacement of the profiles Ver is then ensured by the channel-like design of part 27 . Since with this design of the channel profile 26 a subsequent release of the interlocked channel profiles 26 is very difficult, if at all, is shown in FIG. 13 a further variant in which the additional parts 27 in the drawing below are just the same Have insertion openings 28 for the legs of the channel profile 26 , but these parts 27 are formed on their upper edge in the drawing, for example via film hinges, on the outer surfaces of the legs of the channel profile 26 . Furthermore, these parts 27 have detents 28 at their free ends, which can be engaged in corresponding recesses in the body of the channel profile 26 . If the snap connection is to be released with this clamp, the parts 27 can be swung open, after which the locking connection between the engaged detents 10 and locking recesses 11 can be canceled by engagement by means of a screwdriver or the like.

In the exemplary embodiments according to FIGS. 14 and 15, the bracket of the bracket clamp assembled from a plurality of channel profiles 29 , 30 is comprised of a further bracket 31 , 32 , the leg length of which is greater than the clear height of the assembled bracket, consisting of the channel profiles 29 , 30 , is. The further bracket 31 and 32 has at its free leg ends fasteners 33 for fixed attachment, in particular for order in C-rails. In the base of the further bracket 31 , 32 , a screw spindle 34 is rotatably mounted in a thread formation which has an outer hand 35 and has a cable or pipe support surface 36 at its inner end. The gutter profiles 29 , 30 are aligned with the base of the further bracket 31 or 32 legs (ie pointing downward of the opening), the legs being at the base of the gutter profile 29 below or on the support surface 36 of the Support screw spindle 34 . The contact surfaces 37 of the base of the channel profiles 29 and the contact surface 38 of the support surface 36 each have converging, in particular rounded flanks, so that the free leg ends of the channel profiles 30 and 29 , which are supported thereon, approach each other when the screw spindle 34 is tightened. An additional clamping range is thus realized, which ensures that the inserted cables or pipes are firmly clamped by the legs of the channel profiles 29 , 30 .

In the embodiment according to FIG. 14, an adapter 39 is also arranged at the upper end of the further bracket 31 , by means of which the leg length of the further bracket 31 can be increased, provided that further channel profiles 29 are to be used subsequently.

The adapter has holding means 40 which can be coupled to the point where the fastening means for the fixed fastening of the further bracket 31 are arranged. Furthermore, the adapter in turn has such connection means at its upper, free end that can be used for fixed attachment, for example for use in a C-profile rail.
