Description

The invention relates to a bracket clamp for mounting of pipes or cables, with at least one, preferred as several pipes or cables parallel to each other are arranged one above the other, consisting of an approximately U-shaped bracket, which has a tube inserted into it or cable on the underside to support a building ceiling, rail, profile angle or the same is attachable.

Such clamps are in the prior art known. The U-shaped bracket points to the free leg ends hook-like bends, which are inserted in anchor channels or on the edge edges of profile iron can be hooked. Furthermore there is one with these clamps the basis in a thread formation gripping threaded spindle provided the outside  on the side an actuating handle, for example one Screw head, has and inside the bracket carries a tub-like support surface. In one A clamp or tube can be inserted, whereby then the clamp at the appropriate place fixed profile or fixed rail can be. By means of the threaded spindle, the trough-shaped support surface against the pipe or the Cable sheath can be adjusted so that the tube or Cable pressed against the support profile or the like becomes. There are also clamps to hold known several cables or pipes, in which axles several pipes or cables in parallel one above the other can be held. The length of the stirrups leg of the relative height of the cables or pipes customized. Between the axially parallel one above the other arranged tubes is an insert in each Formed a double channel, so that the Cables or pipes are not directly on top of each other, but with the trough-shaped inserts in between support each other. It is also known about an inserted pipe or an inserted cable  put on another gutter-shaped part, so that the cable or pipe is not attached to bracket parts, but is supported on this trough-shaped part. Especially when arranging several axes tubes arranged in parallel one above the other or Cables in such clamps is the assembly required a lot of effort, since the first cable or pipe has to be inserted into the clamp, then put on a double-channel-shaped part is another cable or pipe can be placed, whereupon a loose double gutter-shaped part must, for example, before the third cable or Pipe can be inserted. Then is possibly the upper gutter-shaped support to arrange part and then the clamp to be attached to the building, for example a profile or a profile rail. Only is a relative fixation of the individual Components to each other by tightening the screw spindle possible, the pretensioning force of  Screw spindle a frictional connection between the individual components is generated.

Based on this state of the art Invention the task of a clamp to create the type mentioned at the beginning their assembly effort is visibly simplified.

To achieve this object, the invention proposes that the bracket by at least one channel profile is formed, on which the same other channels profiles including axially parallel Cable or pipe receptacle arranged one above the other gutters can be plugged on top of each other and so formed stack position are lockable.

With this training, the channel profiles can be made Sheet bent or made of plastic. For fixed mounting, this can be done in the one position of the top gutter profile, which is practically the Forms bracket, have corresponding recesses, to a profile rail or the like  to be able to be pushed. The one in the installation position gutter profiles below are each on the gutter profile above can be pushed and locked in the desired position. These Arrangement makes it possible, for example, in that top gutter profile first a cable or pipe insert and place this top gutter profile fixed, for example on a C profile rail fasten. Then another can follow Cable or pipe in another channel profile be placed, which with his thighs on the legs of the first channel profile pushed on can be and can be locked. If several Cables or pipes are to be kept so the desired number of pipes or cables speaking the desired number of channel profiles stackable together. This is for assembly Training advantageous, since not all axes pipes or cables laid parallel to each other need to be put in a hanger and then the bracket must be attached, but each  single pipe or cable can be in a separate gutter Profile part arranged and on the in the installed position gutter profile located above are attached.

To secure the stack position, it is provided that each Channel profile is U-shaped and at its Legs seen in the transverse to the longitudinal axis of the gutter Longitudinal extension of the same at a distance from one another Has notches and rest recordings.

Only the top channel profile in the installed position, which forms the bow is with a hook or provided similar fasteners a profile rail or a profile iron can be attached are. The ones below in the installed position Channel profiles are each identical, whereby when sliding the channel profiles (across to Axial direction) the corresponding notches in the rest Recordings can grab, so that the stack is secured.  

To prevent the superimposed ones Shift channel profiles axially relative to each other can, it is provided that on the legs of the Channel profiles transverse to the channel longitudinal axis and parallel extending to the legs, the axial Ver sliding of the channel profiles preventing each other Stops are arranged.

These stops can be seen on the edges and / or bars arranged in the middle like projections or recesses or the be formed the same way it the one it allow the channel profiles to run across the axis towards each other, the Webs and recesses form insertion aids, with a relative in the installation position axial displacement of the channel profiles through the Bridge parts and recesses is prevented.

Furthermore, it is preferably provided that in Mounting position of the top channel profile stationary attachable fasteners are arranged.  

Furthermore, it is preferably provided that the location fixable fasteners by a between the legs of the top channel profile attachable, in particular lockable, head piece are formed.

The headpiece can be profiled accordingly that it is on a C-profile rail, on profile iron or the like can be attached. It is also possible that Headpiece with a screw opening provided so that the head piece directly on a Building ceiling or the like screw-fastened is.

It is also preferably provided that the locking lugs at or near the free leg ends of the Gutter profiles are arranged and the Rastaus assumptions beyond the base of the channel profile protruding, extending parallel to the legs and trained from these approaches are.  

With this training, it becomes a double channel Form formed, the upper one for mounting in the installed position a cable or pipe is suitable, so that first this channel profile on the overlying snaps is attachable. The following in the installation position Channel profile can in turn be a cable or pipe take, the locking leg of the upper profile form a gutter shape at the head, which also at least partially includes the pipe or cable. As a result, the base of the channel profile is quasi as Formed double gutter, one of which in the Installation position leg up and on the other Protrude thigh down.

A preferred further development is seen in that the locking lugs and recesses through axis serrations running parallel to the channel profile, in particular undercut teeth are.

This toothing can be designed as a single toothing be, so that only one detent in one  certain target position is achievable. But it can also be designed as a multi-tooth, so that a larger rest area is available that the positive locking of cables or pipes different diameters.

The undercut formation of the serrations is advantageous, especially for training, where the weight of the inserted cables or Pipes a torque on the undercut Teething exercises so that by the weight load the channel profiles increasingly in the closed position are held.

A preferred further development is seen in that the headpiece can be fixed in a fixed position C-profile rail is insertable and one has rectangular locking approach, the Transverse extension in a direction smaller than that Insertion gap of the C profile rail and in the 90 ° turned transverse extension larger than the introducer 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 arranged substantially has rectangular locking lugs, the End face adjacent a greater side length than which has distant.

This training makes it possible to use the head piece to use in profile rails, which different Have slot width.

Another preferred further training consists in that the bracket assembled from channel profiles another bracket is included, the leg length greater than the clear height of the assembled temple is that the further bracket to the free leg end fasteners for fixed attachment has and the base of a screw with external handle and internal cable or pipe support surface in a thread formation is reached.  

The shape of the other bracket corresponds to the essentially the clamp of known clamps, the leg length is chosen so that the maximum necessary number of pipes or cables can be accommodated in the further bracket. To In turn, assembly can be done on the cables or pipes the corresponding channel profiles attached and be locked together so that one in front fixed unit arises, which then in the further Bracket can be used, the stationary, for example can be attached in a profile rail. It is also possible adapter pieces for the other Provide stirrups at the free leg ends are attachable and again recesses or the Have the same, by means of which the adapter pieces can be fastened in profile rails or the like. In this way, the further bracket can be extended provided that such a number of cables or Tubes to be inserted in their total increase the leg length of the further bracket increases. It is also possible to use the other bracket like this broadly train that two or more rows  from parallel to each other and one above the other Pipes or cables including gutter profiles can be accommodated.

A preferred further training is still included seen that the channel profiles with the base of the other stirrups directed legs are and the legs outside at the base of each gutter profile underneath or on the Support surface of the screw spindle can be supported, the contact surfaces of the base and the support surface converging, especially rounded, edges point.

In this training, when tightening the screw spindle of the further bracket each one located therein Channel profile with inserted cable or pipe like this deformed that the legs radially inward on the corresponding pipe or cable jacket to be moved, whereby tension forces acting on the coats be applied.  

Of course it is also possible to get together detached gutter profiles again, using an auxiliary tool, for example a screwdriver, the snap connections releasable are so that the channel profiles are peelable are.

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 inside on the free leg ends of the channel profile 9 , while the locking recesses are formed on the base 13 of the channel profile 9 , extending parallel to the legs and away from this 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 recesses are formed by axially parallel to the channel profile undercut 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 on its upper, free end that can be used for fixed attachment, for example for use in a C-profile rail.

The invention is not based on the embodiment limited, but within the scope of the revelation often variable.

All new, in the description and / or drawing disclosed individual and combination features regarded as essential to the invention.
