Definitions

  • the invention relates to an arrangement with a cable clamp and at least one rope.
  • Rubber bands used which are placed around the objects to be fixed and whose two ends are fixed together by a knot.
  • knots can hardly be opened again or open unintentionally.
  • Cable ties consist of a toothed strip, which is usually made of a rigid plastic. To fix objects, the
  • 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
  • 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.
  • 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.
  • the rubber rings 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.
  • 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.
  • 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.
  • 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.
  • the device described in the cited document must also be placed over the object to be fixed (end of the hair bundle).
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a rope clamp is firmly anchored.
  • the rope clamp has an opening which is adapted to the cross section of the rope.
  • 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.
  • 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.
  • another object eg the towing vehicle
  • 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
  • the nipples 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • Additional element are connected to each other, so that forms a loop of the rope.
  • another element on the loop which encloses the two strands of the loop and is slidable on the loop.
  • 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.
  • a slider, starting from the additional element is now displaced in the direction of the object. This will surround the object surrounding it
  • 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.
