Abstract

The holder has a strip provided with perforations (12) and a detachable clamp to grip the cable. The clamp has two limbs (20) with serrations. They act together with at least one tooth (24) located in the vicinity of the perforation. A pivot (26) links the two limbs and supports a lever (28) with an eccentric clamping surface (30) which pivots on it. The area between the pivot ends and at least one limb is designed so that it permits the limbs to be spread apart of pivoted against one another.

Description

The invention relates to a holder for fixing cables, Lines, hoses or the like with one Breakthrough strip and one, the cable or the same overlapping, releasably fixable on the bar Clamping element, the clamping element having two legs Has teeth with at least one tooth in the area of the openings in the bar interact, and with one bearing piece connected at both ends with a leg on which a swivel lever with an eccentric clamping surface can be swiveled is stored.

Such holders are already known from DE 91 15 403 U1. The holder has the shape of a U-shaped bracket whose cylindrical crossbar is a clamping part in the form of a Swivel lever with eccentric hub is mounted. On the outside the leg of the holder part is toothed, by means of which they are inserted into corresponding through openings Engage openings in the holder's strip. Here the strip for the legs of the clamping element has one such opening or opening that is twice the width of the Leg corresponds, with the side flanks of one Half of the opening with its cross section essentially the thickness the leg of the clamping element corresponds and the other The cross section of the opening is slightly larger than the thickness is the leg of the clamping element. For each leg of the  Clamping elements, an opening is provided on the bar, the one half is used exclusively for inserting the legs, while the other half of the opening with their special narrowed design of the side flanks exclusively for actual locking of the legs is determined. After Push the legs in until they are flush Clamping element on the cable to be fixed is the clamping element just to push or close in the other half of the opening move so that a positive connection on all sides arises between the clamping element and the bar.

Although this well-known holder is quite good in practice has proven itself, there is a desire, in particular in terms of handling when setting the cable or to improve leadership. On the one hand is the postponement of the known clamping element in the opening of the bar right cumbersome, especially if several clamping elements for Attachment of several cables, lines or the like to the Bar are arranged. Also the loosening of the clamping element turns out to be difficult under different conditions especially when several clamping elements are side by side the bar are arranged. Also in the known holder the problem arise that the clamping element is not tight and securely set in the restricted area of the breakthrough is what can also be due to the fact that the legs of the Clamping element through the bar or in the openings are not adequately managed.

From DE-PS 90 36 00 is finally a two-part Spacer clamp known with U- or V-shaped Fastening bracket, over which the lower part of the clamp is put up. The legs of this bracket are to arms extended, on which the clamp upper part by means of a Snap connection is held. To release this snap fastening the legs are compressible by means of handling.

In contrast, the invention is based on the object easy to use holder to provide in particular, the clamping element is light and simple on the bar for the purpose of fixing cables or lines or the same can be determined and released again.

This task is carried out with the holder with the aforementioned Features solved according to the invention that the connection area between the bearing piece end and at least one leg is designed such that it is a Spreading movement of the legs or pivoting against each other allows.

In contrast to the rigid legs of the clamping element of the known holder are the holder of the invention Leg of the clamping element over a certain angular range pivotable on the bearing piece for mounting the pivot lever arranged. This gives the possibility that one or also both legs of the clamping element, for example Loosen the clamping element from the bar or a counter holder V-shaped spread outwards. Then the gearing starts the leg out of engagement with the toothing or at least a tooth in the area of the openings and the bar, so that the clamping element is easily and easily removed from the bar can be. Also attaching the clamping element to the Bar is extremely easy perform by simply in the legs of the clamping element the breakthroughs are inserted. In that at least one of the legs is pivotally arranged on the bearing piece, the thigh can be inserted into the opening pivot laterally outwards so that the teeth of the Legs and the groin just together when inserting slide past. After the clamp so far in the Breakthroughs in the bar have been introduced that the prefers eccentric clamping surface of the swivel lever Cable sheath is on the swivel lever from the  Open position pivoted into the closed position, whereby blocking the teeth of the legs and the groin intertwine and secure fixing of the cable, the line or the like is guaranteed on the holder. The holder according to the invention is used for joining and loosening allows only one hand, the interlocking of the leg over at least one tooth in the area of the opening Groin rattles away.

After a structurally extremely simple design Invention is the connection area as a film hinge educated. The connection area between the leg and the bearing piece is preferred as thin bridge formed, under and above the web between the end face of the bearing piece and an inner surface of the leg a clear width is provided so that the leg with respect to the bearing piece pivotable about an axis predetermined by the web axis is. It is understood that other possibilities of pivotable storage of the leg on the bearing piece can be provided, in particular a two or multi-storey structure of the clamping element then comes into question.

In practice, it has proven advantageous that not only at least one of the legs, but both legs are pivotally connected to the respective bearing piece ends.

Advantageously, according to a particular embodiment of the Invention the leg in the toothed section area facing away via the connection area with the Bearing piece outgoing leg section. In contrast to the prior art, in which the bearing piece in the area of Leg ends is arranged in the present case Molded bearing piece in a central area of the legs, so that the legs extend from the connection area extend to both sides.  

The leg section or sections are advantageous as Handling sections formed and in particular have recessed handles on. The clamping element can be attached on or to detach from the bar simply with two fingers one Hand in the area of the handling sections, so that simple one-hand operation by the fitter is possible is.

The legs of the unmounted are particularly advantageous Clamping element aligned to each other so that the Gear sections after assembly with pre-tensioning the teeth in the area of the openings in the bar Stand by. For releasing the clamping element from the bar can this bias by simply squeezing the two handling sections of the clamping element again be canceled and the clamping element after loosening the Swivel lever again from the openings in the bar be removed.

Furthermore, it has proven advantageous that the Swivel levers vary in width starting from the clamping surface tapered towards its free end. Because of this measure can the swivel lever in the area of the connection to the Rake surface have a maximum width, which is approximately the axial length of the bearing piece minus the clear width in Connection area with the legs corresponds. To his free end towards the pivot lever is tapered, so that in the open position of the pivot lever in which this is aligned approximately axially to the legs, still one Pivotal movement of the legs by pressing the Handling sections is given. This measure will the swivel range of the legs is not restricted, nevertheless is for sufficient mechanical stability of the Swing lever worried.  

According to a development of the invention, it is provided that the swivel lever two in opposite swivel directions acting, preferably eccentric clamping surfaces. This double-acting swivel lever enables a fixation of Cables, lines, hoses or the like in opposite Swivel directions so that the swivel lever is independent of the Installation conditions in the direction of the bar Clamp position can be pivoted. Because none protruding parts are present is unintentional Opening excluded, as well as a risk of injury assembly is minimized. Overall results from the double-acting rocker arm a significant Simplification of assembly. Another advantage of the double acting Swivel lever is that it, again, regardless of the Installation conditions, each in such a closed position can be pivoted that one on the fixed cable, Hose, line or the like cannot pivot into the open position. In other words the pivot lever can be in such a closed position swivel that a possibly attacking tractive force tries to turn the swivel lever further into the closed position. In this Case has the pivot lever with its free end in one Direction which is opposite to the attacking pulling force.

According to another advantageous embodiment of the invention the bearing piece has lifting means to limit the Swivel range of the pivot lever on what is mainly at Swing lever with one-sided eccentric clamping surface for Wear comes. In particular, these slings are such trained that the pivot lever is in a range of can pivot almost 180 °.

According to another advantageous embodiment of the invention is the profiling of the teeth in the manner of a sawtooth formed, both flanks of the sawtooth in one acute angle with respect to a transverse plane of the clamping element  or the bar are inclined. While introducing the Leg of the clamping element, the teeth of the clamping element without further ado about the interlocking in the area of Ridges of the bar can ratchet away, so to speak, grasp the teeth according to Art a ratchet or the like automatically into each other if a force to remove the Clamping element is exerted from the openings. The Lock can only be released if by a Compression of the handling sections of the clamping element the teeth of the clamping element and the strip disengaged have been brought. Also an unintentional loosening of the Clamping element in the closed or locked position located pivot lever not easily possible because the special profiling of the teeth a pivoting of the Leg of the clamping element then practically does not allow.

Alternatively, it is also conceivable that to solve the Locked the swivel lever first relaxed or in the Open position must be transferred and only then by a Compression of the handling sections of the clamping element the toothing of clamping elements and bar out of engagement brought. This variant can be constructed, for example a locking of the lever in the mounting position on the holder realize, for example, by undercut the Sawtooth sections on the holder.

Axial guidance of the clamping element in the openings the bar is given by the fact that these openings of the Last have a depth that is the width of the legs only slightly surpasses.

This axial guidance of the legs of the clamping element in the Breakthroughs can be further improved in that the bar, preferably on the underside, has crossbars, that as a guide for those inserted in the openings  Serve legs of the assembled clamping element. A side Tilting or tilting of the clamping element is thus largely avoided.

Cams or are advantageous on the top of the bar Protrusions provided when attaching the cable or the line by swiveling the swivel lever into the Close position easily penetrate the cable sheath and thus for an extremely secure hold of the cable or line the holder.

Advantageously, the bar has two in substantially parallel openings arranged in rows, so that at Define multiple cables or wires on the holder Clamping elements may be offset and adjacent can be fixed to each other on the bar.

According to another advantageous embodiment of the invention there is a toothing in the area of the opening single tooth or sawtooth or the like or two, in particular laterally adjacent to one another or adjacent teeth arranged one behind the other.

The invention is not only for fixing cables and Lines limited. Leave with the holder according to the invention also define hoses, such as feed hoses in the Area of medical technology, gas hoses, garden hoses or also fire hoses.

Further advantages and possible uses of the present Invention result from the following description of a Embodiment.

Fig. 11 is a sectional view of the holder of FIG. 9 in cross section.

The holder 10 shown in the figures for fixing cables, lines or the like consists of a strip 14 and one or more clamping elements 16 which can be fixed thereon. The strip 14 has a plurality of openings 12 arranged adjacent to one another, one or more teeth or a toothing 24 being provided in the region of the openings 12 . The clamping element 16 has two legs 18 , 20 with teeth 22 which cooperate with the teeth 24 in the area of the openings 12 . The adjacent and substantially parallel or slightly inclined to each other arranged legs 18, 20 of the clamping member 16 are connected to each other via a bearing piece 26, in particular the bearing piece 26 at both ends, one leg 18, 20 are integrally formed. A pivot lever 28 with two preferably eccentrically designed clamping surfaces 30 , 84 is fixed in a clamped manner on the bearing piece and is pivotably mounted about the axis of the bearing piece 26 . Handling sections 86 , such as recessed grips, are provided on both sides of the pivoting lever 28 .

The connecting area 32 , 34 between the end of the bearing piece 36 , 38 and at least one leg, but preferably both legs 18 , 20 is designed as a pivot bearing 40 , 42, that is to say a bearing which permits expansion of the legs 18 , 20 . In particular, the connection area 32 , 34 , as can be seen from FIG. 3, can be designed in the manner of a web, for example as a film hinge. The legs 18 , 20 have, in the area facing away from the toothed section 50 , 52 , a leg section projecting beyond the connecting area 32 , 34 with the bearing piece 26 . This leg section is designed as a handling section 44 , 46 and advantageously has recessed grips 48 or the like.

The connecting area 32 , 34 between the bearing piece end 36 , 38 and the legs 18 , 20 can preferably be designed such that the legs 18 , 20 of the unmounted clamping element 16 are oriented inclined to one another, so that the toothed sections 50 , 52 after the mounting of the clamping element 16 on the bar 14 are under tension with the teeth 24 in the area of the openings 12 of the bar 14 in engagement. As can be seen in particular from FIG. 9, the pivoting lever 28 tapers in terms of the width starting from the clamping surfaces 30 , 84 towards its free end, so that the pivoting lever in the open position shown in FIG. 9 expands the toothing sections 50 , 52 the leg 18 , 20 is not in the way by exerting pressure on the handling sections 44 , 46 . Nevertheless, the lever arm of the pivot lever 28 can be connected to the clamping surfaces 30 , 84 over the full width of the clamping surfaces 30 , 84 . Furthermore, stop means for limiting the pivoting range of the pivoting lever 28 are provided on the bearing piece 26 .

As is illustrated in particular in FIGS. 1 and 8, the profiling of the toothings 22 , 24 is designed in the manner of a sawtooth 56 , 58 . Both flanks 60 , 62 of the sawtooth 56 , 58 are inclined at an acute angle 64 , 66 with respect to a transverse plane 68 of the clamping element 16 or the strip 14 . This measure ensures that the clamping element with the toothed sections 50 , 52 can be easily inserted into the openings 12 with the toothed 24 . However, it is not readily possible to pull the clamping element 16 out of the openings 12 with the toothings 24 , since the toothings 22 , 24 mesh with one another in the manner of a locking mechanism due to the special profiling of the saw teeth 56 , 58 . Removal of the clamping element 16 from the strip 14 is only possible if the toothed sections 50 , 52 of the legs 18 , 20 of the clamping element have been moved into an expanded position by actuating the handling sections 44 , 46 . In this respect, it has proven to be advantageous to arrange the toothing 22 on the inwardly facing surface 70 of the legs 20 of the clamping element 16 .

The openings 12 of the strip 14 have a depth 72 which only slightly exceeds the width 74 of the legs 18 . Furthermore, the strip 14 , preferably on the underside, has transverse webs 76 which serve as a guide for the legs 18 , 20 of the mounted clamping elements 16 . Because of this measure, an otherwise possible tilting movement of the clamping elements, in particular when the cables, lines or the like fixed with the clamping elements 16 on the bar 14 are subjected to tensile stress, is avoided. The upper side 78 of the strip 14 is provided with cams or similar projections which, after the pivoting lever 28 has been moved into the closed position, are easily pressed into the jacket of the cables, lines or the like. The strip 14 has two substantially parallel rows 80 , 82 of openings 12 arranged next to one another. Fastening means for the strip 14 , for example bores 54 or the like, can be provided between the rows. The toothing 24 in the area of the opening 12 can consist of a single tooth or sawtooth 58 or also of two teeth arranged adjacent to one another or adjacent one behind the other.

The holder is handled as follows:
To fasten a cable or the like to the holder 10, the clamping element 16 overlaps the cable or the like, the legs 18 , 20 being inserted into the openings 12 in the strip 14 and the pivot lever 28 in the open position resting on the cable sheath. The toothings 22 , 24 engage in the manner of a ratchet and secure the clamping element 16 from sliding out of the openings 12 . The pivot lever 28 is then transferred from the open position to the closed position, with the cable, the line or the like being slightly compressed between the corresponding clamping surface 30 , 84 and the upper side 78 of the strip 14 by means of one of the eccentric clamping surfaces 30 , 84 . By means of this pressure force exerted on the clamping element 16 , the toothings 22 and 24 firmly engage in one another, whereby it is practically impossible due to the special design of the profiling of the saw teeth 56 , 58 to actuate the handling sections 44 , 46 when the clamping element 16 is in the closed position To release pivot lever 28 . The clamping element 16 can only be released when the toothed sections 50 , 52 of the clamping element 16 are spread apart by one-hand operation and the clamping element 16 can be removed from the strip 14 .

Of course, it is also possible that the pivot lever 28 has only one eccentric clamping surface. However, the double-acting swivel lever described above offers the possibility that the fixation takes place in opposite swivel directions, as is indicated in FIGS. 9 and 11 by the dash-dotted position of the swivel lever 28 . This ensures that the pivot lever can be pivoted into the closed position facing the bar, regardless of the installation conditions, so that no protruding parts of the holder are present. Another advantage of the double-acting pivot lever 28 is that it can be pivoted into such a closed position, again regardless of the installation conditions, that a tensile force acting on the fixed cable, hose, line or the like does not pivot the pivot lever 28 in the open position can. In other words, the swivel lever 28 can be swiveled into such a closed position that any tensile force that may be attacking tries to turn the swivel lever further into the closed position. In this case, the free end of the swivel lever points in a direction which is opposite to the tensile force acting on it.
