Definitions
- the present invention relates to a clamping device and a method for securing an object to a guide element with a clamping device.
- Climber either via a rope which runs between him and a second security person or a fixed point (stand), with intermittent intervening hooked at regular intervals, or a rope which firmly on a rock wall, buildings, masts o.a. artificial or natural structures.
- the first described safety and climbing method is generally called the ascent, while the second method is called via ferrata
- a via ferrata set This set consists of two ends, each with a carabiner, a drop shock absorber and a binding device. Basically, both ends of the via ferrata set are hung in the safety rope. At each anchorage, the one, then the other, end of the set must be hung first. That way you are secure at all times. Nevertheless, a fall on a via ferrata always carries a high, often even fatal, risk of injury, as the top of the fall usually falls several meters unrestrained down the safety rope. A violent impact on rock ledges and edges also increases the risk of injury. bell on climbing climbs should therefore be avoided at all costs.
- the invention is solved with a clamping device and a method for securing an object to a guide element with a clamping device according to the independent claims.
- a clamping device has a Clamping sleeve with a clamping area and a clamping body.
- the clamping sleeve is designed to guide a guide element, such as a cable or a guide rail, along an inner surface of the clamping sleeve.
- the inner surface has in the clamping area along the guide direction, for example, the cable direction or the
- the guide member has a wedge-shaped inner profile, which along a central axis, e.g. a cable central axis or a guide rail central axis, the guide element tapers.
- the clamping body is movably mounted in the clamping area between the inner surface and the guide element such that a blocking position can be taken in, in which the clamping body can be clamped between the inner surface of the clamping area and the guide element.
- a relative movement between the guide element and clamping sleeve is prevented due to the jammed clamp body.
- a method for securing an object, in particular a person, a climber or an object, to a guide element (cable, guide rail) with a clamping device.
- a guide element is guided along a clamping region of an inner surface of a clamping sleeve of the clamping device.
- the inner surface in the clamping region has a wedge-shaped inner profile along the guide direction of the guide element, which extends along a central axis of the
- the clamping body is movably mounted in the clamping area between the inner surface and the guide element such that a blocking position can be assumed, in which the clamping body is clamped between the inner surface of the clamping area and the guide element.
- the described clamping device can be used when climbing along a guide element, e.g. along a guide rail or a rope to be moved in a climbing direction, wherein in a reverse direction to the climbing direction of the clamping body is guided by the wedge-shaped clamping region in the radial direction to the central axis (Seilstoffachse) such that the smallest diameter of the wedge-shaped clamping sleeve the clamp body to the Guide element (rope, guide rail) presses, so that a clamping force is generated, which prevents further slippage of the clamping device along the guide element in the reverse direction.
- a guide element e.g. along a guide rail or a rope to be moved in a climbing direction
- guide element can be understood to mean a guide rail or a cable, wherein the guide rail or the cable can be attached along the object (mountain wall, building wall) in order to fix the climber to the cable or the guide rail can have any diameter
- the diameter of the collet may be adapted to receive and slide along the guide member, and the diameter of the collet may be greater than the diameter of the guide member, by means of movement Nevertheless, a clamping device with a firmly standardized clamping sleeve can be adapted to different diameters of guide elements.
- the guide element has a central axis, for example a cable central axis or a guide rail central axis, wherein the central axis extends along an extension direction of the guide element, for example the cable or the guide rail.
- clamping sleeve can be used to describe a sleeve which is open or closed along the guide direction (eg the cable direction) .
- the clamping sleeve can, for example, completely enclose the guide element (eg hollow cylinder shape) or have a U-profile (U-shaped profile) the clamping sleeve only partially surrounds the guide element (rope).
- wedge-shaped may be an inner profile of an inner surface of the clamping sleeve are described which, for example, along the guide direction a decreasing cross-section or
- the wedge-shaped clamping sleeve can have an inner profile which can taper in the radial direction to a central axis (cable central axis) of the guide element.
- the clamping body can be mounted in the clamping area between the inner surface and the guide element such that the clamping body is movable along the clamping area in the guide direction and in a direction radial to the central axis, so that in a blocking position of the clamping body between the clamping area and the guide element can be clamped.
- the clamping body can be mounted in the clamping region of the clamping sleeve in the direction of the central axis (cable central axis) radially and longitudinally movable relative to the central axis. Due to the relative movement between the clamping sleeve and the guide element, the clamping body is moved accordingly within the clamping sleeve. Along one Ascending direction or climbing direction along the guide member, the clamping sleeve moves along the climbing direction, said relative climbing movement between clamping sleeve and guide element moves the clamping body along the clamping area in a freewheeling position.
- the clamping body In the free-running position, the clamping body is in the region of the wedge-shaped clamping region, in which the clamping sleeve has the largest possible diameter or not the smallest diameter. In other words, in the region of the largest diameter, the largest distance between the inner surface of the clamping sleeve is given and in the region of the smallest diameter, the smallest distance between the inner surface and the guide element is given. In freewheeling position of the clamp body no clamping forces are transmitted or built up by the wedge-shaped inner surface of the clamping sleeve and the guide element.
- the clamping body is moved along the wedge-shaped inner surface by the relative movement between clamping sleeve and guide element in such a way that the clamping body moves in the direction of the region of the clamping sleeve with the narrowest cross section or the smallest Clamping sleeve diameter of the clamping sleeve moves.
- a clamping force is transmitted to the clamping body and on the guide member by the wedge-shaped inner surface. This clamping force generates a jamming of the clamping body between the clamping sleeve and guide element, so that the blocking position occurs. In such a blocking position is not relative Movement between clamping sleeve and guide element along the locking direction possible.
- the clamping sleeve If the clamping sleeve is again moved in the climbing direction relative to the guide element, the clamping sleeve with the wedge-shaped inner surface slides over the clamping body and the guide element such that this clamping body again moves in the direction of the larger diameter of the clamping sleeve and thus no longer transfers clamping force to the guide element becomes. As a result, the clamping device can be moved again in the climbing direction along the guide element.
- a climber can continuously climb up along a guide rope attached to a wall, for example, without having to produce a fixed connection to a wall hook after a certain climbing section.
- a climber can climb the wall continuously in the climbing direction, in the event of a crash almost directly the clamping body transmits a clamping force to the guide element (cable, guide rail) and a fall movement in the reverse direction is prevented. This ensures a uniform short fall distance at any time or in each climbing section of the climber, since in the reverse direction, the relative movement between the clamping sleeve and guide element is almost immediately prevented.
- the clamping device can provide a blocking position, the fall path to each point of climbing on a guide element is constant and minimized so that there is little case delay due to a drastic delay at high fall speeds.
- the clamping device further comprises a housing.
- the housing is designed to receive the clamping sleeve in such a way that the clamping sleeve is movable relative to the housing along the central axis. Since the clamping sleeve is housed in the housing, the clamping sleeve can be protected, for example against external influences such as a rockfall or other jamming. Without a housing, for example, the clothing of a climber could prevent the movement between the clamping sleeve and guide element. By collapsing the ferrule, pinching, e.g. clothing, and thus provide better functionality.
- Clamping device further comprises a spring element.
- the spring element is arranged between the housing and the clamping sleeve such that the clamping sleeve along the guide element due to the spring force in a clamping position is movable. In the clamping position of the clamping body is due to the wedge-shaped inner surface between the
- the spring element can thus be generated a spring force which biases the clamping sleeve in a rest position such that the blocking position is set without movement of the clamping device on the guide element as a starting position. Only when the Climber by pressing a climbing or climbing movement along the climbing direction of the guide member shifts the clamping device, the bias or the spring force of the spring element is exceeded, so that the clamping sleeve moves only relative to the guide member and the clamping body releases, so that no more clamping force is transferred to the guide element.
- the clamping device can be preset in its safest setting. In other words, are located by the bias by means of the spring element, the clamping sleeve and the clamping body in an initial position always in the blocking position, whereby the security can be increased.
- the housing has a first guide groove extending perpendicularly (radially) to the central axis.
- the clamping body is guided displaceably in the first guide groove.
- the clamping body can be mounted such that it is displaceable exclusively in the desired direction, for example radially to the central axis.
- the clamping body can move along the first guide groove away from the guide element (remove from the central axis), when the clamping sleeve is displaced such that the inner surface of the clamping sleeve in the region of the guide groove is further spaced than the diameter of the guide element. Then, the clamping body along the first guide groove can move away from the guide element, so that the guide element is no longer jammed by the clamping body. This allows the clamping device along the guide element to be moved. Furthermore, removal of the clamping device from the guide element can be facilitated. Likewise, adaptation to different diameters of the guide elements is possible by the clamping body guided in the radial direction.
- the embodiments of the first guide groove also apply to the second guide groove described below.
- the clamping sleeve has a second guide groove extending along the wedge-shaped inner surface of the clamping sleeve.
- the clamping body is guided displaceably in the second guide groove.

An abrasion of the clamping body and the inner surface of the clamping sleeve can thus be reduced.
- the clamping body can be forcibly guided by the first guide groove and the second guide groove.
- the second guide groove may for example be a slot-shaped groove or a through-groove, wherein the clamping body extends through the second guide groove and is slidably mounted in the first guide groove.
- the clamping body In a relative movement between the clamping sleeve and the housing, the clamping body is positively guided.
- a movement of the clamping sleeve along the guide element (rope) causes the second guide groove leads the clamping body perpendicular to the guide element or leads away from the guide member.
- the clamping body is additionally supported in a direction perpendicular to the central axis by the first guide groove creates a movement dependence between the housing and the clamping sleeve. If, for example, the housing is moved in the direction of the guide direction and relative to the clamping sleeve, a positively driven movement of the clamping body is produced, namely perpendicular to the central axis of the guide

- FIG. 4 shows schematically a sectional view of the clamping device from FIG. 3.
- FIG. 1 shows a clamping device 100 which has a clamping sleeve 101 with a clamping region 104 and a clamping body 102.
- the clamping sleeve 101 is designed to guide a guide element 107 along an inner surface of the clamping sleeve 101.
- the inner surface has in the clamping region 104 along the guide direction of
- Guide element 107 (e.g., along the rope direction of the rope) has an inner profile which tapers along a central axis M.
- the clamping body 102 in the clamping region 104 between the inner surface and the guide element (rope, guide rail) 107 is movably mounted such that a locking position is ingested, in which the
- Clamping body 102 is clamped between the inner surface of the clamping portion 104 and the guide member 107.
- the clamping body 102 is movable along the clamping area 104 in the guide direction and along a direction radial to the central axis M, so that in a blocking position of the clamping body 102 between the clamping area 104 between the inner surface of the clamping portion 104 and the guide member 107 can be clamped.
- the clamping sleeve 101 partially encloses the guide element 107 with a U-shaped profile, as shown in FIG. 1, or completely in the form of a hollow cylinder.
- the guide element 107 may be a guide cable or a guide rail, which is fixedly attached to a wall to be climbed (building wall or mountain wall).
- the clamping sleeve 101 is formed wedge-shaped in the radial direction to the central axis M of the guide member 107.
- the wedge-shaped design of the inner surface of the clamping sleeve 101 in the clamping region 104 means, for example, that the clamping sleeve 101 has a narrowest diameter at one point and at another Point along the guide member 107 has a largest diameter.
- the distance of the inner surface of the inner profile in the clamping region 104 in the direction wedge tip to the guide member 107 is narrowest and in the opposite direction to the wedge tip, the inner surface is furthest from the guide member 107.
- the clamping body 102 can move.
- the clamping body 102 may, for example, have a spherical shape or a cylinder or roller shape.
- the clamping body 102 may be formed such that it is rollable along the guide member 107 and along the inner surface of the clamping sleeve 101, so that a friction loss of the clamping body 102 on the inner surface of the clamping sleeve 101 or on the guide member 107 is reduced.
- the reverse direction SR is shown in the arrow direction. If the clamping device 100 moves in the direction of the locking direction SR, this simulates, for example, a crash of the climber along the guide element 107. If the clamping device 100 moves in the direction of the locking direction SR, the clamping sleeve 101 also moves in the direction of the locking direction SR.

- the clamping body 102 can move along the inner surface of the clamping sleeve 101. In this case, the clamping body 102 move in the opposite direction to the taper of the inner surface of the clamping sleeve 101, so that the clamping body 102 can no longer transfer a clamping force Fk on the guide member 107.
- the clamping body 102 are thus, for example, when floating the clamping sleeve 101 in the climbing direction floating or playing stored, so that no power transmission between the clamping body 102, the clamping sleeve 101 and the guide member 107 takes place.
- the entire clamping device 100 can be moved in the direction of the climbing direction, or against the locking direction SR in the climbing direction.
- Clamping device 100 can be provided, which can be constantly moved along the climbing direction on a guide rope, without the climber must make further attachment steps. Another backup on different hooks in the climbing wall can be neglected. Thus, the length of fall as a result Crash are minimized because immediately after the beginning of the fall of the climber, the clamp body 102 is movable into a blocking position, wherein the clamping device 100 is fixed to the guide member 107.
- a receiving device 106 is shown, to which a tether or a carabiner can be attached, which fastens the climber to the clamping device 100.

This can ensure that with no movement of the clamping device 100 is always the Locking position is taken to prevent an automatic slippage of the clamping device 100 on the guide member 107, for example.
- a first guide groove 109 may be introduced, which extends radially to the cable center point M.

- the clamping body 102 In a relative movement between the clamping sleeve 101 and the housing 103, the clamping body 102 is forcibly guided.
- a movement of the clamping sleeve 101 along the guide element (cable) 107 causes the second guide groove 110 leads the clamp body 101 perpendicular to the guide element (rope) 107 or away from the guide element (rope) 107.
- the clamping body 101 is additionally supported in a direction perpendicular to the central axis M by the first guide groove 109 If, for example, the housing 103 is moved in the direction of the central axis M and relative to the clamping sleeve 101, a positively driven movement of the clamping body 102 and corresponding to the housing 103 is generated and vice versa.
- a further spring element 115 can be arranged in the first guide groove 109 or the second guide groove 110, wherein the further spring element 115 biases the clamping body 102 in the direction of the guide element 107.

- each locking pin 113 is displaceably mounted in the clamping device 100, for example on the housing 103.
- Each locking pin 113 in this case has an area which can slide over the opening of the U-shaped profile of the clamping sleeve 101, so as to provide a closed cross-section or a closed loop, in which the guide element 107 can be enclosed.
- the locking pin 113 can also have a latching groove 201, which can be latched with corresponding first latching elements 111 and second latching elements 112.
- the locking pin 113 can be pushed for example over the open side of the U-profile of the clamping sleeve 101 to enclose the guide member 107 and engage the second latch member 112 in the latching groove 201 in a defined closed position to prevent further displacement of the locking pin 113. Also, in an open position of the lock pin 113, the first lock member 111 may be engaged with the lock groove 201 to hold the open position of the lock pin 113. Thus, unwanted adjustments of the opening of the U-profile of the clamping sleeve 101 can be avoided and, for example, an unintentional withdrawal of the guide member 107 can be prevented from the clamping sleeve 101.
- a tension spring may be arranged in the clamping device 100 to apply a biasing force to the locking pin 113, which biases the locking pin 113 into the closed position.
- the locking pin 113 is brought into an intermediate position, that is in a position in which no latching element 111, 112 is engaged in the latching groove 201, the locking pin 113 permanently in the closed position. A slipping of the guide member 107 from the clamping sleeve 101 in an intermediate position of the locking pin
- the actuation button 114 may be arranged on the clamping device 100 or on the housing 103.
- the actuation button 114 may, for example, by pressing in Direction of the first latch member 111 and / or the second latch member 112 are pressed so as to push out the first latch member 111 and / or the second latch member 112 from the Einrastnut 201 to selectively move the locking pin 113 in a closed position or in the open position.
- Fig. 1 and Fig. 2 further shows two locking pins 113.
- Both locking pins 113 can be moved individually or together.
- these may be e.g. be attached to an actuating disc, so that upon rotation of the actuating disc both locking pins 113 are moved simultaneously and opened.
- the actuation button 114 can also be set up such that an actuation leads to a decoupling of all first and / or second latching elements 111, 112.
- Fig. 1 and Fig. 2 show an embodiment of the clamping device 100, in which the housing 103 and the locking pins 113 are circular.
- a locking of the clamping device 100 by means of the locking pin 113 can be implemented with one hand.
- the climber can press the actuating button 114 and thus simultaneously release all the locking pins 113 to move the locking pins 113 from the closed position to the open position and vice versa.
- the locking pins 113 can be attached to a gripping surface or an actuating disk, which by the
- FIGS. 1 and 2 the climber can press the actuating button 114, thus unlock the locking pins 113 and move the locking pin 113 in a closed position or in an open position in a clockwise or counterclockwise direction by means of the grip element 116.
- Fig. 3 shows a sectional view of the clamping device 100 of FIG. 1 in an operating state in which the clamping sleeve 101 opposite to the locking direction SR along the guide member 107 is movable.
- the clamping body 102 has now moved, for example because of the relative movement between the clamping sleeve 101 and the guide element 107, in a region of the clamping region 104 in which there is a greater distance between the inner surface of the clamping sleeve 101 and the guide element 107.
- the distance is so great that no clamping force FK is transferred from the clamping sleeve 101 via the clamping body 102 to the guide member 107.
- the clamp body 102 is no longer clamped. Since no clamping force Fk acts more, the clamping sleeve 101 and thus the entire clamping device 100 can move along the guide member against the locking direction SR.
- the distance of the inner surface of the clamping sleeve 101 to the guide element 107 in the largest diameter of the clamping sleeve 101 may correspond to a diameter of the clamping body 102.
- the region of the largest diameter of the inner surface of the clamping sleeve 101 in the clamping region 104 can also be selected larger than the diameter of the clamping body 102.
- a further spring element 116 can be installed, which spring force forces a movement in the direction of the smallest diameter of the inner surface of the clamping sleeve 101 in the clamping region 104.
- FIG. 3 shows the locking mechanism with the locking pins 113, the latching elements 111, 112 and the handle element 116.
- Fig. 4 shows schematically a sectional view of the clamping device
- Fig. 4 shows the clamp body 102 in a side view.
- the clamp body 102 has a cylindrical shape, with pin-like shoulders or pins projecting from the base surfaces. These pins can be in the first guide groove 109 in the housing 103 and / or in the second guide groove 110 in the clamping sleeve
- the clamp body 102 can be guided specifically.
- the cylindrical main body In addition to the cylindrical main body, the
- Clamping body 102 also spherical, cylindrical or cone-like body shapes.
