Abstract

What is described is an arrangement comprising a cable clamp and at least one cable. The arrangement is distinguished by the fact that the cable clamp has at least two openings arranged next to one another through which the at least one cable or in each case one cable is guided with the formation of two cable portions passing through the openings, that the openings each have a clamping slot in a mutually facing opening region, and that the two cable portions are held directly outside adjacent to the openings by a loop of the at least one cable or of a further cable, by means of which loop the two cable portions can be forced into the respective clamping slot.

Description

Arrangement with a rope clamp and at least one rope

Technical area

The invention relates to an arrangement with a cable clamp and at least one rope.

State of the art

For bundling or fixing objects are often cords or

Rubber bands used, which are placed around the objects to be fixed and whose two ends are fixed together by a knot. However, not everyone is practiced in tying knots, even in unfavorable case, knots can hardly be opened again or open unintentionally.

As an alternative to knot so-called cable ties are known and used in many ways. Usually fastenings can only be solved with cable ties by the cable tie is severed and thus destroyed. However, there are also embodiments of resealable cable ties, which can be solved again and thus can be used multiple times.

Cable ties consist of a toothed strip, which is usually made of a rigid plastic. To fix objects, the

Cable ties led around this object and one end of the

Plastic strip led into an opening at the other end of the plastic strip. There, the teeth snap in, so that the plastic strip can not be pulled out of the opening again. To ensure that the teeth on

If plastic strips snap into place sufficiently, cable ties consist of less flexible plastics, e.g. Polyamide or POM. Since the plastic strip is hardly stretchy, however, cable ties also provide a largely rigid

If the fixed objects are subject to movement, the cable tie fixation may loosen after some time. In addition, it can by the comparatively rigid material also come to damage to the objects to be fixed.

In addition to cable ties and the so-called hook and loop fasteners are well known and widely used. Velcro fasteners in the form of elongated fabric-like strips can e.g. to bind objects to fix them. They can be solved easily with significant noise. Like the cable ties, velcro fasteners are usually not extensible in the longitudinal direction and therefore only partially able to keep objects susceptible to long-term stress.

Other known fasteners such as cable clamps are often also rigid, very limited in their adjustment, or complicated to handle, so sometimes additional tools for tightening are required.

Classic rubber bands, which are also widely used for fixing objects, have the advantage over the possibilities already mentioned that they have a high elasticity and thus can hold the applied once and required for fixation voltage long term. Also, the force acting on the objects due to the elasticity is well controllable. The challenge with the use of rubber bands is to fix the rubber bands themselves. Usually the rubber bands are knotted for this purpose.

When the rubber rings are closed, they are usually placed over the respective object (eg a bag) in single or multiple layers. For the user, this process is sometimes cumbersome. With one hand, the objects to be fixed must be held and stretched with the second hand, the rubber band and placed in the same step on the objects to be fixed. In addition, such rubber rings are set in their respective length, so that in each case one of its length suitable rubber must be selected for the fastening task. Often there is also no possibility to put the objects to be fixed over, since they are closed and have no end, or the end is inaccessible. For example, a tree trunk rarely has the Possibility to put something over the treetop, so that a closed rubber ring can not be used here unrestricted for attachment of objects.

Expander ropes circumvent the need for knotting by hooking the rubbers at one or both ends. However, this results in the disadvantage that the expander rope from its length to the respective

Fixing task must fit. The user can not set the length freely.

Classic tarpaulin tensioners, as shown in the specification FR1450821 A or US6389659B, can not be continuously adjusted in their length. The cable length, or in FR1450821 A, the distance between the two balls to each other, largely determines for which size of objects to be fixed, the tarpaulin tensioner is particularly suitable. Only by a multiple wrapping can be responded to different sizes of the objects to be fixed, the effective force is then discretely from the number of wraps.

Further, also referred to as cord stopper rope clamps are known in which the rope is locked with a mechanism having a stopper element, as shown for example in the documents US5697128, US5896623. The

Locking and releasing are effected by operation of the mechanism by operation. Such cord stoppers are widely used, for example, as a closure on sleeping bags, as lacing on trousers, jackets or backpacks. The safety against unintentional release then increases with the restoring force of the mechanism. The disadvantage here is that the user must first overcome a force to release the mechanism before he can move the cord stopper on the rope. Most such mechanisms are implemented in several parts with the inclusion of an additional return spring. However, mechanisms are also known which consist of a single part, as shown for example in EP0775845B1. From the document EP1029466 a device suitable in particular for binding hair is known which consists of a rubber band whose two ends open into a tension element and on the thereby resulting

Rubber band loop a sliding clamp is mounted, which serves to tighten the resulting loop. Like the classic rubber band already mentioned, the device described in the cited document must also be placed over the object to be fixed (end of the hair bundle). In addition, the corresponding clamping device consists of several individual parts, including a return spring, which brings disadvantages in the production and in the operation with it. The user must first release the lock caused by the return spring before moving the clamping element along the

Rubber band loop can move as needed to fix an object.

The document GB2042047 discloses a fastening device for cables with a conical slot. The conical slot allows fixation of the rope by self-locking by pulling the rope into the tapered area of the slot. However, the rope must also be secured against unintentional loosening by means of a knot resembling a cross-strike, which makes the use of the system more difficult.

In the application US4787660A, one of the two cable ends is pulled by a tapered cross-section similar to GB2042047 and thereby fixed. The force required to fix the rope is only during the

Applied fixation process, so that the rope end can be released during movements again from the tapered cross-section.

The document US5791022A discloses a tube with two tapered openings in the outer wall through which the two rope ends of a rope are passed. As with the previously cited documents US4787660A and GB2042047, the cable is locked in that it is guided in the tapered cross-section. The font FR2878925 also uses a tapering cross-section on the outside Rope clamp to secure a rope and thereby keep bags closed. In these devices mentioned, which use a tapered cross-section for fixing the rope in the cable clamp, there is usually the risk that the jammed ropes can be released by a Fehlbelastung again from the clamping area.

The document US2016108989A describes an element for fastening objects with a resilient double-stranded rope. On the rope a rope clamp is firmly anchored. To fix an object outgoing from the cable clamp rope loop is performed completely around the body to be fixed and then locked in the cable clamp, the lock can be done at any position of the cable loop. The rope clamp has an opening which is adapted to the cross section of the rope. During the fastening process, the rope is loaded with tension and thereby reduces its cross-section, so that it can be guided into the groove of the cable clamp. The application NL7700029 is very similar to the aforementioned application US2016108989A, the difference being that it is a single-stranded version of the rope.

The document US4896403 describes a fastening device for a

two-strand rope in the form of a toothed plastic element. To lock a loop of the two-stranded rope is pulled through the plastic element and secured over there teeth against loosening.

US Pat. No. 5,767,700 describes a fixing element for locking a loop which has been guided through the fixing element. The loop may serve to hold or fix another object. This further object to be fixed then exerts a force on the fixing element, whereby the loop is prevented from being released again from the fixing element.

The document DE6931658U describes a cable clamp, for example for towing a vehicle. The rope clamp is the simplest

Embodiment only from a disc with two slots. The first end of the rope is thereby fixed in the rope clamp by friction, whereas the second end of the rope leaves the rope clamp, without being fixed by friction in this. A tensile force must act on this second end of the rope in order to keep the first end of the rope fixed in the clamp. At the open end of the rope then another object (eg the towing vehicle) can be attached.

The document DE6941 149U describes a tow rope with a cable clamp for producing a size-adjustable loop. The protection against loosening takes place in the described invention in that the tow rope contains clamping nipples at its ends. The diameter of the nipple is larger than the diameter

Diameter of the rope. In the unlocked state, the nipples can be inserted into the cable clamp, but slip during locking in a slot whose gap is chosen so that the nipples can not slip out through the gap.

From DE29705188U1 a tension member for fixing the two free ends of a ball chain, as used for example in blinds, disclosed. The tension member has two openings, with a converging tapered cross-section, in which balls of the ball chain are positively fixed.

In the utility model DE20209943U1 a device for adjusting the cable length in hammocks is described. The device consists of a provided with three holes rope clamp through which one end of the serving for fixing cable is guided, the holes have no special shape. Due to the rope guide through the three holes of the rope clamp creates a kind of node construct, which counteracts the release of the rope.

In the application GB2147937 a clamp for setting the rope length is presented, as it is known, for example, in a similar form from the application US6389655B2 and finds widespread for bracing tents or for mounting equipment on boats. The clamp has an elongated shape and contains two holes for the passage of the rope, the hole diameter of the Rope cross-section are adjusted. One end of the rope is fixed to one of the two holes while the rope is slid through the second hole.

In the document US20040194259A1 or US 7 076 845 B2 a cable clamp is described, which has an elongated shape and has along this form one or two holes for the passage of a rope. The rope passed can enclose an object to fix it, and then it is returned again and slipped around the two ends of the elongated rope clamp. To hold the fixation, however, a tensile force must continuously rest on the entire rope. The end of the rope facing away from the fixation area can therefore not remain loose, but it must have a tensile force. The in the application EP2101081

The article described is similar to the structure of the application US20040194259A1, however, the one or both holes are designed in the form of grooves instead of through-holes.

Another fastener is disclosed in Greek specification GR20100100420A. In it a rope is described, whose two ends over a

Additional element are connected to each other, so that forms a loop of the rope. In addition, there is another element on the loop, which encloses the two strands of the loop and is slidable on the loop. To fix an object, the loop can be passed around this object and the additional element can be guided through the loop after the loop has completely enclosed the object. To further fix this initially still fairly fragile attachment, a slider, starting from the additional element, is now displaced in the direction of the object. This will surround the object surrounding it

Loop pulled even further and locked due to the friction of the slider on the rope. However, the slider is barely secured against it, to move away from the object to be fixed and so unintentionally solve the attachment again.

It is known that some cable clamps can cause damage to the objects to be fixed. In the already cited application GB2147937 is a Presented rope clamp, which contains targeted elastic areas, only to such

To avoid damage.

In some of the cited documents, in particular US5791022A,

US4787660A and GB2042047, the rope or ropes during the

Fastening process by a tapered cross section on an additional component (the cable clamp) out. The tapering cross-section leads to an increase in the frictional force between the rope and the rope clamp and thereby secures the rope against loosening. If an unfavorable load, in particular a force against the direction of the rejuvenation acts on the rope, there is nevertheless the risk that the rope will come loose again from the rope clamp.

From US 2017/0108081 A1 a fastening device is to be taken which comprises a closed rope or a closed band, which passes through a

cohesive connection or via a separate element is divided into a smaller and a larger loop. In the area of the larger loop, an elongated toggle button is arranged, which is arranged transversely of two parallel

prevent. The toggle button is slidably disposed along the larger loop for purposes of length adjustment of the fastener. The

Fastener can be used in different ways, namely to form a single, a double or a self-locking closure.

FR 2 445 462 A2 discloses a hook element with a through opening passing transversely through the hook element, through which an elastic cable can be passed. The opening has a first opening area with a round

Cross-section whose cross section is greater than the cable cross-section. The first opening area partially overlaps with a second round

Opening area whose cross-section equal to the rope cross-section in the relaxed Condition is such that the rope can still slide through the second opening area. In the region of the overlap two projections are formed, between which on the one hand the rope can be pulled under elastic deformation, on the other hand, however, an unwanted

From FR 2 855 227 A1 a cable clamp is known, which is designed in the form of a flat elliptical cylinder and which is penetrated in the axial direction by an opening. This has a first opening area, through which the rope can be guided without clamping. The first opening region merges in the radial direction into a second, narrowly tapered opening region into which the cable attached to the cable clamp can be pulled in and clamped.

DE 199 06 120 A1 describes a device for infinitely adjustable fixing of the size of a rope loop placed around an article. The

Device has a holding part for one end of the rope and a clamping part for releasably clamping the returning rope after looping. The clamping part is designed as a cable guide channel, whose side walls have toothed ribs.

Presentation of the invention

The invention has for its object to provide an uncomplicated arrangement with a rope clamp and at least one rope, with the objects

attached and / or held together and that is easy, inexpensive to manufacture, easy to use and reusable.

The solution of the problem underlying the invention is specified in claim 1. The concept of the invention advantageously forming features are the subject of the dependent claims and the further description in particular with reference to the illustrated embodiments.

According to the solution, the arrangement with a cable clamp and at least one cable is characterized in that the cable clamp has at least two juxtaposed openings through which the at least one cable or rope in each case to form two cable sections passing through the openings

passed through. The openings each have a clamping slot in an opening area facing each other. Both cable sections are immediately outside the openings adjacent to a wrap of the at least one rope or another rope taken by the two cable sections in the respective clamping gate are zwingbar. In particular, the two cable sections can be constrained by the looping towards one another in the respective clamping slot.

In a preferred embodiment, the at least one cable or the further cable is elastically extensible or at least elastically extensible

Coupling element connected, that a resulting elastic restoring force forces the cable sections in the clamping scenes. The at least one coupling element may be a section in the at least one cable or the further cable, which has a higher elasticity than the corresponding cable. However, the coupling element can also be designed in the manner of a longitudinally elastic spring which connects the cable ends of the at least one cable or of the further cable. It is also conceivable, however, to couple at least one end of the rope, preferably both ends of the rope, to an object via or one coupling element each. A along the at least one cable or the other cable, the previous elongation counteracting elastic restoring force causes in the area of the wrap that they want to contract. This results in an inward force, the cable sections towards each other in the respective

Klemmkulissen forces. It is particularly advantageous that these resulting from the expansion force or bias of the rope even at unfavorable loads, as they might occur, for example, due to mutual movement of objects to be fastened together, the cable sections in the Holding clamps. The said ropes can be identical or different. In particular, said ropes may comprise exactly one fiber or more fibers. As materials for the rope or for the ropes are in a special way elastomeric materials and rubbers or elastically woven tapes. Particularly preferably, the at least one cable, the ropes and / or the other rope has a Shore A hardness in the range of 40-80 and an elongation at break of at least 100%. In order to improve the handling and to save the rope, the at least one rope, the ropes and / or the other rope may be made of an elastomeric material, which is covered by a tissue.

In a particularly preferred embodiment, the cable clamp is made in one piece. Preferably, the rope clamp is made of a rigid, but at least of a less elastic material than the at least one rope, the ropes or the other rope. As material for the rope clamp are particularly suitable

Plastics such as polyamide, POM, ABS, PC, PE, PVC or similar in their hardness range plastics, metals such as aluminum or steel, wood and / or

Materials with a modulus of elasticity of at least 100 MPa or a Shore D hardness in the range of 50 - 90. The rope clamp has a body with a

Longitudinal extension, which is greater than its transverse extent. Preferably, the cable clamp has a total length in the longitudinal direction of extension, which corresponds at least five times, more preferably at least seven times the diameter of the undeformed rope. The openings enforce the body in

Enforcement directions that are oriented parallel to the transverse extension direction or at an angle of <30 ° to the transverse direction of extension. The openings need not necessarily be made parallel to each other in this case. The respective enforcement direction can be defined as an imaginary connecting line between the centers of gravity of the inlet and outlet surfaces of the respective opening.

Preferably, the openings each have a cross-sectional shape, which tapers in the direction of the other opening continuously or stepwise. In this case, the cross-sectional shape in the tapered region has at least one region with one clear width with w <0.7 d _s , preferably w <0.6 d _s , particularly preferably w <0.5 d _s , on which is part of the respective clamping slot.

In particular, the cross-sectional shape of the cable sections is deformed by the clamping slot, for example from circular to a flattened shape. In addition to the change in the cable cross-section, a displacement of the cable material in the cable direction can also occur due to the clamping. Depending on the elastic properties of the rope or ropes, the cable cross section approaches the circular shape with the diameter d _s at a greater or smaller distance from the openings. The cross-sectional shape of the openings has an extension in

Longitudinal direction or in a direction perpendicular to the respective

Enforcement direction, here referred to as width, on, which consists of a first region and a second region and in total at least twice the rope diameter d _s corresponds. Particularly preferred is a width bi of the first region with bi> 1, 3 ^* d _s and a width of the second region with b> 1, 5 ^* d _s .

Preferably, the openings are mirror-symmetrical, with a

Normal vector of the plane of symmetry is oriented parallel to the direction of the longitudinal extent. Particularly preferably, the openings are mirror-symmetrical and parallel.

Each of the clamping scenes preferably has at least two mutually facing contact surfaces, with which the cable sections come into contact at least during clamping. In this case, at least one of the contact surfaces a

Surface structuring to increase acting between the cable sections and the clamping backdrop friction forces. The contact surfaces are formed by opposite opening wall sections delimiting the opening.

In a further preferred embodiment, the cable clamp has a slot which passes completely through the cable clamp, wherein the openings in the area are interconnected between the clamping slots via the slot such that the cross-sectional shapes of the openings merge with each other to form a single closed contour. This embodiment may have advantages in the production, as well as a rope ring, such as a closed rubber band, can be subsequently introduced into the cable clamp, which is no longer possible with two separate openings or holes. Alternatively, the cable clamp may have two slots which make the openings accessible from the outside from the longitudinal direction of extension. Again, there is the possibility to subsequently introduce a rope ring, since the two openings or holes are held open by the slot to the outside of the rope clamp. In principle, therefore, in each of these preferred embodiments, the cable sections can be introduced via the slot or slots transversely to the respective enforcement direction in the openings.

Preferably, the cable clamp on two surface sections, in which the

Open respectively open, wherein at least the surface portion on sides of the wrap in a region which comes into contact with the wrap, concave. Due to the concave design of the cable clamp in the direction of the enforcement of the openings or the enforcement direction of the cable sections carried out increases the force of the first wrap on the two strands in the direction of the clamping scenes or in the direction of the second region. The security against loosening is thereby further increased.

The cable ends are connected in a preferred embodiment directly by a cohesive, positive, or force or frictional connection or indirectly by means of a connecting element or a tension element to form a closed cable ring, so that on both sides of the cable clamp each have a loop, namely a first and a second loop forms. The wrap is part of the first loop that includes the

Rope sections on the side of the first loop or on the side of the second loop. The tension element simplifies the handling of the arrangement in that it does not have to be pulled directly on the rope or on the ropes. In addition, that can Tension element be used in the manufacturing process as a connecting element to connect an open rope, such as a rubber band to a cable ring or close.

Preferably, the cable clamp is relative to a plane perpendicular to

Transverse extension direction a first and a second side can be assigned. On the first side of the rope clamp to the rope sections subsequent first

Cable sections are directly or indirectly connected to a first object. On the second side of the cable clamp to the cable sections subsequent second cable sections are connected to each other or at least one securing means is arranged by means of a complete pulling the second cable sections can be prevented through the openings. The other rope is fixed with its loose ends to form a loop on the first object or a second object. Instead of attaching two ropes to the first object, a loop or two open ends of a rope can be passed through an opening passing through the first object. In this case, the first cable sections and the second cable sections are part of the same cable. In the simplest case, the securing means may be knots on the ends of the rope whose diameter is greater than the inside width of the openings. It is also conceivable, however, a circlip through which the open ends of the rope are passed.

In a further preferred embodiment, an additional element, in the form of a clamping ring, is provided with at least one passage opening, through which cable sections emerging from the cable clamp can be guided, and through which the exiting cable sections occupy a distance corresponding to a distance of the cable sections guided in the openings if they are fixed in the clamping scenes.

In a further preferred embodiment, the surface structuring is spatially directed. The surface structuring has at least one, preferably two or more ribs on the at least one

Contact surface are arranged and include the transverse extension direction at an angle between 0 ° and 15 °. 5

The advantage of the arrangement according to the invention is that the

Different objects can be fixed to itself or to other objects. In particular, the assembly is in a variety of ways for attaching, wrapping, bundling or closing objects

usable in different sizes. The arrangement can be after use

solve uncomplicated and non-destructive and can then be reused. The force acting on the object to be fixed can be adjusted continuously and can be readjusted even after fixing has already taken place. When using an elastic rope, such as a rubber band, the force effect remains due to the elasticity of the rubber band even when the object is moved or exposed to vibration. The user does not need to press any additional fixing mechanism. The use of elastic ropes and the manner of wrapping also has the further advantage that the objects to be fixed are touched only by the rope or the ropes of elastic material, but not, or at least only with little force, of the Rope clamp, so the risk of

Damage to the objects to be fixed is low. The for the

Inventive arrangement required components are simple and

inexpensive to produce. It is particularly advantageous that on the rope or band no adapted to the size of the cable clamp, prefabricated or manufactured by means of an additional connecting element loop must be provided.

Ways to carry out the invention, industrial usability

Figures 1 a-c show different variants of an arrangement of a

Rope clamp and exactly one rope, which can be arranged according to the invention for fixing objects. 1 a shows the simplest case of a cable clamp 1 and a closed cable ring 2, for example in the form of a closed rubber band, in which the rubber band is guided through two similar openings 3, 3 'of the cable clamp 1. The rubber band is then divided by the rope clamp 1 in two sides, each forming one of the rope clamp 1 outgoing rubber band loop 21, 22. The loop size changes each time by moving the Rope clamp along the rope or the cable sections. The two openings 3, 3 'of the cable clamp 1 are here arranged parallel and mirror-symmetrical and have a tapered opening cross-section, wherein the two openings 3, 3' tapered facing each other tapered. For the assembly, the cable 2 can be guided with the open ends through the openings 3, 3 'and then connected in a material-locking, positive or positive fit (FIG. 1 a) or by means of a connecting element 20 (FIG. 1 b). In Fig. 1 b is additionally or alternatively to

Connecting element 20 a cohesive, non-positive or positive connection 19 of the rope ends indicated. The connecting element 20 shown in FIG. 1 b can simultaneously serve as a tension element and improve the handling of the arrangement in that it does not have to be pulled directly on the rope. The connection of the rope ends can also be done by simple knotting (not shown). Fig. 1 c shows a further variant in which the rope ends are individually secured against accidental slipping out of the openings 3, 3 '. For this purpose, for example, at each end of the rope a securing means 39, 39 '- as such may also serve a knot at the end of the rope - are attached, as shown simplified in Fig. 1 c.

In Fig. 1 d, a rope 2 is shown with an elastic coupling element 43. In this case, the rope 2 itself and also the part of the rope which later forms the wrap 6 (FIG. 3a) can have a lower elasticity. The

Restoring force, which then forces the cable sections 4, 4 'into the clamping scenes 5, 5', results from an elastic stretching of the coupling element and is transmitted via the cable. Such a coupling element may for example be an elastic spring.

FIG. 2 a shows the basic structure of the cable clamp 1. This has a body 30 with a longitudinal extension 7 in the longitudinal direction of extension 31 and a

Transverse extension 8 in the transverse direction of extension 32 and a high extension 9 in the direction of extension 33. The openings 3, 3 'pass through the cable clamp completely in the direction of enforcement, which here coincides with the transverse extension direction. The openings 3, 3 'here have, by way of example, a cross-sectional shape on, which consists of the segments of a large and a small circle, which are each connected by straight lines, which open tangentially to the circles. The openings 3, 3 'thus have tapered opening areas 14, 14', which form the clamping scenes 5, 5 '.

However, the penetration directions 34, 34 'of the openings need not be aligned parallel to the transverse extension direction 32, nor must the openings through the cable clamp 1 have the same cross-sectional shape or cross-sectional area. Thus, the cable clamp 1 shown in Fig. 2b, for example, openings 3, 3 'with enforcement direction 34, 34', which include an angle α, a '0 with the transverse extension direction 32. In addition, Fig. 2b also shows

Openings 3, 3 ', whose cross-sectional area is not constant through the cable clamp, but which widens in Fig. 2b to the rear in the direction of enforcement 34, 34'.

In Fig. 2c, the cable clamp 1 is shown in cross-section, together with the

Cable sections 4, 4 ', respectively before and after the clamping. Evident is the significant cross-sectional reduction and cross-sectional shape change that the

Rope sections 4, 4 ', which preferably have a round rope cross section in the undeformed state, experienced at entry or in the terminal backdrop.

In Fig. 2d, the various opening areas are specified in more detail. The openings 3, 3 'have a cross-sectional shape, each having a first region 13, 13' and a respective second region 14, 14. The first region 13, 13 'is preferably adapted to the cable cross-section, that the rope or the cable sections 4, 4 'in the undeformed state or in only slightly stretched state, in which the

Rope sections 4, 4 'experience a slight reduction in cross-section, preferably less than 20% of the cross-sectional area, through which the cable clamp can be pulled without experiencing any jamming. Slipping of the rope clamp without external influence but can by such

Dimensioning of the first area 13, 13 'can be avoided. The first region 13, 13 'preferably has at least one extension in Longitudinal direction bi, bi ', which corresponds at least to the rope diameter d _s .

The second region 14, 14 'has a reduced inside width w <0.7 d _s, preferably w <0.6 d _s, more preferably w <0.5 d is _s.

The second area 14, 14 'defines the contour of the clamping slot 5, 5' of the respective opening 3, 3 'in the considered cross-sectional plane. Also, the second region 14, 14 'preferably has at least one extension in the longitudinal direction b, b', which corresponds at least to the rope diameter d _s . Preferably, the first 13, 13 'and the second region 14, 14' starting from the respective center of the region on a distance D to each other, which corresponds at least to the rope diameter.

If the cable sections 4, 4 ', which have an undeformed circular cable cross-section, are introduced into the second region 14, 14' or into the clamping guide 5, 5 ', they undergo at least one cross-sectional deformation so that they flatten out against the contact surfaces Assume 16 adapted cross-sectional shape (Fig. 2c). Due to the change in cross section, in the cable sections 4, 4 '

Restoring forces induced that lead to a pressing of the cable sections 4, 4 'to the opposite contact surfaces 16 of the clamping scenes 5, 5' and thus to an increase in the friction between the cable sections 4, 4 'and the contact surfaces 16. With appropriate design of the Klemmkulisse the

Contact surfaces 16 merge into each other. Due to the increased friction, the cable clamp 1 can not be moved or only with significantly higher force along the rope 2. A further increase in the frictional forces between the deformed cable sections 4, 4 'and the contact surfaces 16 can be achieved in that the contact surfaces 16 at least partially have a friction-increasing surface structuring. Moreover, this deformation or

Pinching also lead to an extension of the rope sections. The induced by the extension of the cable sections restoring force causes an increase in the clamping force. Between the first region 13, 13 'and the second region 14, 14' may extend a transition region 29, 29 ', in which the cross-sectional shape of the opening 3, 3' tapers continuously or abruptly.

Fig. 3a shows how a portion of the loop 21 forms the loop 6, the running in the openings 3, 3 'cable sections by acting in the direction of the taper of the openings 3, 3' (see arrows in Fig. 3a and arrows in Fig. 2c) directed elastic force in the clamping scenes pulls or counteracts emergence of the cable sections from the clamping scenes. FIGS. 3b and 3c show two variants of how the arrangement according to the invention for fixing objects, here by way of example for bundling pins 25, can be used. The first loop 21 is guided around the objects / pins 25 and then slipped over the second loop 22 and the cable clamp 1. The first loop 21 encloses the pins 25, as well as the emerging from the cable clamp 1 sections of the first loop 21 (or the second loop 22 in Fig. 3c). To lock the arrangement, the second loop 22 is now pulled away from the user by the objects / pins 25 to be fixed and the cable clamp 1, wherein the cable clamp 1 is pressed by the user to the objects / pins 25 to be fixed. As a result, a tensile stress is exerted on the first loop 21, which leads to the penetration of the two cable sections 4, 4 'into the tapered, second regions 14, 14' of the openings 3, 3 ', which comprise the clamping guides 5, 5', and which both cable sections 4, 4 'thus arrested. Since the tension on the first loop 21 is maintained even with slight movements, the two are

Rope sections 4, 4 'in the tapered second portions 14, 14', which are part of the respective clamping scenes 5, 5 ', held and secured. The fastening is now complete. To release the connection, it is sufficient to pull the cable clamp 1 away from the fixed objects 25.

One way of fixing one object to another can be realized by passing the first loop 21 through an eyelet or opening in one of the objects and then slipping it over the second loop 22 and the cable clamp 1. This creates a similar arrangement as in Fig. 5a, only with the difference that not rope ends are fixed by two different ropes on the object 25, but the first loop 21 by a

Opening in the object 25 (not shown in Fig. 5a) is passed.

An alternative way in which the first loop 21 may comprise the cable clamp 1 is shown in FIG. 3c. In this variant, the first loop 21 is slipped over the two longitudinal ends 36, 36 'of the terminal 1, instead of having to be guided over the second loop 22. Also in this variant results in a force from the first loop 21 on the two guided by the terminal

Rope sections 4, 4 ', so that they are pressed and locked in the tapered, second regions 14, 14' of the openings 3, 3 '.

Figures 4 and 5a and 5b show a second embodiment of the

Arrangement according to the invention, in which a cable 2 is passed through the cable clamp 1 with the formation of a loop, and the loop 6 is formed by a section of a further cable 40. The two open ends of the rope 2 and of the further rope 40 can be fastened to one and the same object 25 (FIG. 5a) or to two different objects 25, 26 (FIG. 5b), the two different objects 25, 26 respectively Be part of another object. Thus, for example, according to Fig. 5a with the ropes of the

inventive object 25 are fixed to the object 26.

In order to fix the object 25 to the object 26, as shown in FIG. 5a, the first loop 21 is guided in a first direction and the second loop 22 is guided around the object 26 in a second direction and the first loop 21 passes over the second one Loop 22 and the rope clamp 1 slipped so that both loops together enclose the object 26. Subsequently, the loop 22 is pulled away from the object 26 by the user while the cable clamp 1 is pressed by the user to the object 26. As a result, on the first loop 21 a

Tensile applied, which leads to the locking of the two cable sections 4, 4 'in the (in Figure 5a not visible) clamping scenes 5, 5'. In FIGS. 5a and 5b Optionally elastic coupling elements 43 indicated, which have a higher elasticity than the cable 2 and the further cable 40. Such a coupling element 43 may be an elastically extensible rope that is part of the at least one cable 2 or the other cable 40, an elastic spring, or even an elastic part of objects to be fixed, such as an elastic fabric to a backpack, from the the ropes come out.

To fix the object 25 on the object 26, as shown in Figure 5b, the first loop 21 is slipped over the second loop 22 and the cable clamp 1 so that it encloses the emerging from the cable clamp 1 sections of the second loop 22. To tighten the assembly, the cable clamp is held by the user and pulled on the second loop 22 so that parts of the rope pieces 1 1, 1 1 'are pulled through the cable clamp and the loop 22 increases to form a tensile stress. Due to the size of the

User applied traction between the cable clamp 1 and the loop 22, the force acting between the object 25 and the objects 26 tensile force is determined. Between the pieces of rope 1 1, 1 1 'and the other cable 40 then sets a balance of power, so that acting on the rope 40 and the first loop 21 tensile force causes the two cable sections 4, 4' in the

Clamping scenes 5, 5 'to be pulled.

Instead of a rope 2, the formation of a loop through the

Rope clamp 1 is guided, two separate ropes (not shown) can alternatively be performed through the openings 3, 3 'of the cable clamp 1, the ends of which are connected cohesively, non-positively or positively, so that in turn forms a kind of loop. The ends can also remain open.

In a preferred embodiment, a still

Securing element / additional element 28 may be provided in the form of a displaceably mounted clamping ring (FIG. 4) which is arranged on the side of the cable clamp facing away from the loop and by which the cable sections are held directly outside the cable clamp 1 at a distance from one another Distance of the cable sections 4, 4 'in the clamping scenes 5 corresponds (Fig. 4). If the clamping ring 28 is pushed in the direction of Seilklennnne 1, this also causes a force on the two cable sections 4, 4 'in Seilklennnne 1 in the direction of the taper. The security against loosening can be increased with such a clamping ring 28.

FIGS. 6a and 6b disclose two embodiments of the cable clamp in which a previously closed cable ring is still connected to the cable clamp 1

can be assembled. For this purpose, the cable clamp 1 according to Figure 6a has a slot 17 which passes through the cable clamp 1 as the openings 3, 3 'completely and the two openings 3, 3' connects over their entire extent through the cable clamp 1 therethrough. A rope section of the rope ring may then pass through the slot 17 from one of the openings e.g. 3 in the other opening, e.g. 3 ', be pulled over.

Alternatively, as shown in Figure 6b, the apertures 3, 3 'may extend outwardly through a respective slot 17', 17 ", i.e. over their entire extent

Be open in the direction of enforcement, so that the cable sections 4, 4 'of the cable ring from the outside into the openings 3, 3' can be inserted. It is particularly advantageous if the slot width is smaller than the rope diameter d _s , so that the cable clamp 1 can not inadvertently come off the cable ring. Of course, the must

Slit width, taking into account the elastic properties of the rope 2 and the cable clamp 1 be chosen to be large enough that the or the cable sections 4, 4 'transverse to the cable direction through the slot 17 and the slots 17', 17 "can be pulled through.

FIGS. 7 show two openings 3, 3 'with an alternative cross-sectional shape. The slight widening 41, 41 'of the openings 3, 3' in each case in the direction of the other opening causes the user of the cable clamp to tactfully perceive a type of engagement when locking the cable sections in the clamping slot. However, the widened area is still sufficiently narrow dimensioned that a clamping of the rope can be done in this area. The openings 3, 3 ' 5 here have a two-dimensional cross-sectional shape, which is asymmetrical with respect to the longitudinal extension direction 31. In general, an asymmetrical design of the cross-sectional shape can offer to the

Rejuvenation direction of the openings 3, 3 'to the direction of the end of the wrap 6 ultimately on the cable sections 4, 4' acting forces (see arrows in Fig. 3a) adapt.

Fig. 8a shows a body 30 of a rope clamp 1, in which the surfaces in which the openings 3, 3 'open, are made plan. In contrast, Fig. 8b shows a cable clamp 1 with a waisted body 30. This has at least in the longitudinal direction 31, a concave line 18, so that the contraction of the wrap 6 is facilitated due to the elastic force acting along the rope 2 restoring forces. In Fig. 9 a button-like design rope clamp 1 is shown, in which at least one of the surfaces is concave. Here too, the concave shape 18 serves to reinforce the force effect of the loop 6 on the two cable sections emerging from the clamp 1 and thus to increase the safety against loosening of the cable clamp 1.

FIGS. 10 to 12 show further different embodiments of the invention

Cable clamp. Thus, Fig. 10 shows an elongated rope clamp 1, the ends 36, 36 'are not planed, but - for example, tapered - taper. The ends 36, 36 'but can also be performed rounded. By the tapered ends 36, 36 'can be, for example, the first loop 21 easier pull over the cable clamp 1, whereby the handling is improved.

Figures 1 1 and 12 show cable clamps whose body in

Transverse extension direction 32 are bent and thus form a concave portion 18 at least on one side, so that the contraction of the

Wrap 6 due to the elastic acting along the rope 2

Restoring forces is facilitated. The cable clamp 1 shown in FIG. 12 also has areas 37, 37 'which are widened in the vertical direction and which have a handle structure 38 are equipped. This shape additionally facilitates the handling of the rope clamp. 1

In Figures 13a and 13b, a further advantageous embodiment of a cable clamp 1 is shown. The rope clamp 1 is characterized by a non-linear taper of the cross-sectional shape of the opening 3, 3 'from the first region 13, 13' over the

Transition region 29, 29 ^' to the second region 14, 14' from. In the second region 14, 14 ', the contact surfaces are oriented almost parallel to one another, ie

Normal vectors n1, n1 'of the lower contact surfaces 16 shown in FIG. 13b close in the second region with the normal vectors n2, n2' of the upper ones

Contact surfaces 16 an angle γ, γ 'from 165 ° to 180 °. The resulting only small change in the clear width w, w 'of the opening 3, 3' in the second region 14, 14 ^' is particularly advantageous in terms of clamping action and allows even better protection against accidental release of the rope 2 from the clamped State. Due to the over-proportional increase in the clear width of the openings 3, 3 'in comparison to the second area 14, 14' at least in the transitional area 29, 29 ', the cable clamp 1 can be used in contrast to a

Cable clamp with in the longitudinal direction 31 linearly changing

Form opening width shorter. The rope clamp 1 is very easy to use and has a very good clamping action. In the following, particularly preferred values are given for the openings 3, 3 'of the cable clamp 1 in this exemplary embodiment:

0.7 ^* d _s <w1, w1 '<1, 2 ^* d _s

0.3 ^* d _s <w, w '<0.5 ^* d _s (For example, the inside width w, w' over the width b, b 'can be from 0.5 ^* d _s to 0.3 ^* d _s . lose weight)

1, 1 ^* d _s <b1, b1 '<1, 3 ^* d _s

1, 1 ^* d _s <b, b '<1, 4 ^* d _s

The total width 15 is in a range between 2.3 ^* d _s and 2.8 ^* d _s . 7

FIG. 14 shows a further preferred embodiment of the cable clamp 1

shown. This has at the contact surfaces 16 a directional structuring 44, 44 ', for example in the form of a corrugation or grain on. The structuring 44, 44 'is preferably oriented in a direction consistent with the

Transverse extension direction 32 forms an angle ß, ß 'between 0 ° and 15 °. The thus directed structuring 44, 44 'represents a further improved protection against unwanted loosening.

A structuring oriented parallel to the transverse extension direction 32, i. ß, ß 'equal to 0 °, offers as a further advantage of the user tactile perceptible

Engage.

A directional structuring 44, 44 'with angles ß, ß'> 0 °, in particular with angles ß, ß 'between 5 ° and 15 °, additionally leads to the cable sections 4, 4' when moving the cable clamp 1 in the direction of When loosening the cable clamp 1, the cable sections 4, 4 'are forced out of the respective clamping link 5, 5'. The directed

Structuring thus provides additional support to the invention underlying preferred principle of action, according to which the wrap 6 exerts an inwardly directed force on the cable sections, so they are forced towards each other in the respective clamping scenes.

A rope clamp 1 with a directional structuring 44, 44 'with angles ß, ß'> 0 ° then has a preferred side on which then the wrap 6 should come to rest, or a direction in which the cable clamp 1 to close should be moved, and a direction opposite thereto, in which the cable clamp 1 should be moved to open. In embodiments with tension member 20, as shown in Figure 1 b, the preferred side is defined by the tension member 20 (cable clamp moves away from the tension member 20 during tightening). at

Embodiments such as in Figure 1 c is also a preferred page given after here only on one side of the cable clamp 1, a loop 22 is formed. If the entire fastener the operator does not suggest a preferred direction, so it is appropriate to provide the cable clamp 1 and / or the cable 2 with a corresponding feature. In this way, for example, be made known to the user, which loop 21, 22 he to the

should attach fastened object.

The concrete design of the directional structuring 44, 44 ', for example, number, geometry (among other height, width, length, cross-sectional shape, angle ß, ß', distance of the individual structures, especially in view of the mating of the material of the rope and the material of the cable clamp resulting sliding friction, the geometry of the opening 3, 3 'in particular in the second region 14,14', the elastic properties of the rope and the force to be used for pulling / loosening force to be selected.

Directed structuring 44, 44 'can be, for example, one or more rib-like elevations arranged in parallel on the contact surfaces 16

be provided, for example, by 0.03 ^* ds to 0.1 ^* ds rise from the respective contact surface 16. In the case of a plurality of rib-like elevations arranged in parallel, for example, they may have a spacing of between 0.1 ^* ds and 0.3 ^* ds. The longitudinal direction of the rib-like elevations or

Ribs in this case corresponds to the direction of structuring.

In principle, beyond the examples shown, all are disclosed

Body shapes can be combined with all opening shapes. All the cable clamps can be used in all shown embodiments of the arrangement according to the invention.
