Definitions

  • the invention relates to a clamping device with a guideway extending along a guide direction for guiding a cable element through the clamping device, at least one clamping body movably mounted in the guideway for clamping the rope element in the guideway, if this is pulled against the guide direction by the guideway, and at least one Biasing element, through the biasing force of the clamping body is urged from a release position into a clamping position in which it narrows the guideway more than in the release position.
  • rope element is generally a rope-like element such as a natural fiber or synthetic fiber rope, a wire rope, a chain, a Cable, a rope, a cord o. The like understood, which is suitable for guiding through a carabiner opening.
  • a via ferrata set which regularly has two carabiners, a shock absorber and a binding device. Both carabiners of the set are always hooked into the rope element. At each anchoring of the rope element then first one, then the other carabiner of the set must be umgeograph so that the climber is secured at any time on at least one carabiner. Nevertheless, in case of a fall, the climber usually falls over several meters unobstructed down despite securing, because the anchorages are several meters apart. Therefore, falls on via ferrata should be avoided at all costs.
  • two clamping bodies protrude laterally into a guide track in which the cable element is guided.
  • the guideway has a wedge-shaped Inner profile, which tapers along a central axis of the cable element, wherein the clamping body are mounted in the guide track so movable that they can assume a clamping position in which the clamping body between an inner wall of the guide rail and the cable element are clamped.
  • the direction in which a rope element can be pulled through the guideway, without any jamming of the rope element is hereinafter referred to as the guiding direction.
  • the clamping device can be pulled when climbing in a climbing direction along the cable element, wherein the climbing direction of the guide direction is opposite (here is not drawn on the cable element, but on the clamping device held thereon).
  • the clamping body are guided by the wedge-shaped region of the guide track in the radial direction to the middle of the rope, that the guide track is narrowed, so that the clamping body are pressed against the cable element. Further pulling of the cable by the clamping device against the guide direction is thus prevented.
  • a position in which the clamping bodies are so far away from a center of the guideway that the cable element can be easily inserted into the guideway is referred to below as the release position.
  • Adjusting the clamping position in the release position is in the publication WO 2010/142690 A1 described clamping device laboriously, since this requires a complex mechanism must be operated. Possibly. the climber shy away from the effort associated with moving the clamping device at seemingly simple climbing sites, which can lead to dangerous situations and climbing accidents.
  • This object is achieved by a development of the clamping device described above, which is characterized essentially by an actuating mechanism for adjusting the clamping body from the clamping position to the release position with two operating portions which are movable towards each other for actuating the actuating mechanism by pressing force.
  • the clamping body can be adjusted from a clamping position narrowing the guideway into a release position which releases the guideway for insertion of the rope element, in that two actuating sections of an actuating mechanism are moved toward one another.
  • the one operating section is moved towards the guide track starting from one side of the guide track and the second actuating section moves toward the guide track starting from the opposite side of the guide track.
  • the invention is based on the knowledge that in the document WO 2010/142690 A1 described rotary-push mechanism for adjusting in the release position is not optimally adapted to the anatomy of a human hand.
  • the simplest and most comfortable hand movement which can apply a considerable amount of force quickly and easily, is a pressure movement between the thumb and the residual fingers of one hand.
  • the thumb can operate in the clamping device according to the invention, the first actuating element, while the residual finger or the index finger, the second actuating element can be actuated, wherein the actuating portions are moved towards each other by the thus acting counter-pressure forces, whereby the actuating portion is actuated.
  • the two actuating portions are coupled by means of the actuating mechanism to the at least one clamping body such that a movement of the actuating portions toward one another displaces the clamping body from the clamping position into the release position, in which it narrows the guideway less strongly.
  • the actuating mechanism may comprise various types of force deflection mechanisms, of which a force deflection mechanism will be described below by way of example.
  • the actuating portions are each parts of a lever, wherein the two levers are preferably pivotable about transversely, in particular approximately perpendicular to the guide direction axes of rotation.
  • the levers may extend in the unactuated state substantially parallel to the guide direction laterally next to the guideway, wherein they are arranged on opposite sides of the guideway.
  • the pivoting of the lever can take place in such a way that a rear end of the lever which has the actuating portion is pivoted onto the guide track. In the release position, the levers then run at an angle to the guideway.
  • the two levers can be arranged substantially symmetrically about the guide track and each have at a front end the axis of rotation and at a rear end of the actuating portion.
  • the actuating portion may be an outer surface of the lever facing away from the guideway, wherein the outer surfaces are particularly well grasped by the fingers of a hand and can be moved towards each other. Parts of the inner surfaces of the lever can strike each in the release position on an outer wall of the guideway. The user is directly displayed in this way that the release position is reached and the cable element can now be placed in the released guideway.
  • the front ends of the levers can each be attached to a base part of the clamping device via a pivot pin or the like, so that a pivoting of the levers relative to the guide track is possible.
  • a better clamping effect can be achieved by two movable in the guideway clamp body, between which the cable element can be clamped in the clamping position, and which are each arranged closer in the clamping position in the middle of the guideway than in the release position.
  • the middle of the guideway corresponds essentially to the center of the guided in the guideway rope element.
  • the clamping action can be further improved in that the clamping body in the clamping position abut against opposite side walls of the guide track, wherein the side walls gradually diverge in the guide direction.
  • the side walls of the guideway can form a wedge-like or gradually widening profile. In the clamping position, when the cable element is pulled against the guide direction by the guide track, this leads to the clamping of the clamping body between each of the cable element and the associated side wall, whereby the clamping action is made possible.
  • the movement guidance of the clamping body can be effected in that each of the clamping body is guided in a guide groove extending along the guide direction, wherein the guide grooves extending from a clamping portion in which the clamping body are guided in the clamping position to a release portion in which the clamping body in the release position are guided, wherein the two release portions are spaced from each other further than the two clamping portions.
  • the two actuating sections are actuated, the two clamping bodies can be guided along the guide grooves, in each case, from the clamping sections into the release sections which are further apart, so that a narrowing of the guide track is released.
  • the guide grooves may be arranged in a plate-like bottom surface of the guideway substantially symmetrical to the center of the guideway, wherein the two clamping body can protrude starting from the respective guide groove in the interior of the guideway.
  • the closest mutual distance of the two clamping sections perpendicular to the guide direction can be less than 1 cm, preferably less than 0.6 cm, while the widest mutual distance of the two release sections can be more than 2 cm, preferably more than 3 cm.
  • an angle between the clamping sections of the guide grooves and the guide direction is in each case smaller than 30 °, preferably smaller than 15 °, but preferably greater than 5 °, while an angle between the release portions of the guide and the guide direction is greater than 30 °, preferably greater than 60 °.
  • the guide grooves in the guide direction can be removed at an acute angle of less than 30 ° from the center of the guide track.
  • This small angle leads in the unactuated state at any time to a close concern of the clamping body on the cable element guided therebetween, even if act through the cable element transversely directed forces on the clamping body.
  • An angle greater than 5 ° is useful so that the clamping body approach the cable element in its movement against the guide direction.
  • the angle between guide groove and guide direction can gradually increase up to more than 30 °, preferably more than 60 °. This causes that on actuation the operating portions of the clamping body last quickly remove each other in the radial direction, so that the cable element can be easily inserted therebetween.
  • According to a further aspect of the invention is to be reliably prevented that an unintentional force on only one of the actuating portions displaces the clamping body in the release position.
  • An unintentional release of the cable element could cause the clamping action is no longer sufficiently fast attacks, or in extreme cases even to a drop of the clamping device from the rope and thus to a loss of security.
  • Such unintentional force is, for example, possible if the clamping device is accidentally pressed while pulling along the cable element against the rock wall or the like.
  • a securing mechanism provides that the clamping bodies are adjustable from the clamping position to the release position by an essentially identical pressure force on the two actuating sections, while on the other hand the actuating mechanism is characterized by greatly differing pressure forces on the two actuating sections, in particular in one Compressive force on only one of the two operating sections, in a blocking position is adjustable, in which a further movement of the two operating sections is blocked to each other. It is virtually ruled out that both operating sections are inadvertently actuated essentially with an equal compressive force in the amount, so that the risk of unintentional adjustment into the release position is minimized according to the invention.
  • the two actuating portions When the magnitude of the compressive forces acting on the two actuating portions is identical or substantially identical (with the compressive forces in the opposite direction), the two actuating portions are movable towards each other, thereby moving the clamping bodies to the release position.
  • “Essentially identical” may include cases where the magnitude of the force varies by +/- 30% or +/- 50%. However, if the amounts of force differ even more, and in particular when only one of the actuating portions a compressive force acts, the actuating mechanism in a blocking position out in which further movement of the operating portions is blocked from each other. Then also an increase of the unilaterally (asymmetrically) acting pressure forces does not cause the clamping body to move into the release position. Rather, the clamp body remain in the clamping position.
  • Such a blocking position can be realized according to the invention by two guide tracks, each with a substantially parallel to the guide track extending release track, run into the guide elements guided therein when adjusting in the release position, and each having a branching off barrier track, in which the guide elements when adjusting in the Restrict locking position.
  • the locking tracks do not run essentially parallel to the guide track, but transversely thereto, preferably starting from the release track in the direction of the guide track.
  • the guide tracks and the guide elements guided therein are each assigned to one of the two actuating sections, wherein the joint actuation of the two actuating sections with essentially the same compressive force leads to a run-in of the guide elements into the release tracks.
  • the release tracks are sufficiently long so that the guide elements guided therein reach a front end of the release track at the earliest when the clamping bodies are arranged in the release position.
  • the locking track is short so that the guide element guided therein already reaches a front end of the locking track when the clamping bodies are still arranged in the clamping position and not yet in the release position.
  • the guide tracks are introduced into the rear portions of the lever having the actuating portions.
  • the guided in the guide tracks guide elements may be guide pins and / or guide pins, which are forcibly guided at a pivoting of the lever along the guide tracks, so that they coupled thereto via articulated struts carriage along to shift the direction of leadership. Due to the symmetrical arrangement of the lever with guide tracks introduced therein as well as the symmetrical arrangement of the struts with guide elements attached thereto around the guide track, the pressure force of the climber acting transversely to the guide track can be deflected into a thrust force directed in the direction of the guide track, which shifts the slide ,
  • the actuating mechanism may comprise a force deflection mechanism which transmits the compressive force acting on the two actuating sections when actuated transversely to the guide direction onto a carriage such that the carriage with the clamping body coupled thereto is movable in the guide direction.

  • the holding members may be disposed between front and rear abutment surfaces of the carriage so as to follow only movement of the carriage in and against the guiding direction while their movement is released transversely to the guiding direction. Since the holding parts engage around the side walls of the guideway, they follow the radial course of the side walls during a movement in the axial direction, the course of the side walls of the guideway corresponding to the course of the two guide grooves.
  • the biasing member for returning the clamp body to the clamped position may be a spring member such as a coil spring mounted on the carriage and on a base portion of the clamp device. Due to the bias of the spring element of the carriage can be pulled against the guide direction, which in turn leads to the coupled to the carriage clamp body are guided against the guide direction in the clamping portions of the guide grooves in which they narrow the guideway, and what the other causes the operating portions to be urged outwardly away from the track to an unactuated condition.
