Definitions

  • the invention relates to a descender, in particular for mountaineering or speleology and also for rescue.
  • This descender can be used with a single rope or a double rope.
  • This type of device is used today by mountaineers for abseiling on single or double ropes.
  • An already old and still widely used device is in the form of an eight with two closed rings, one of which serves as a means of attachment to the mountaineer's harness.
  • This device has several faults, including the installation of this descender requires that it be completely free, which represents a big risk because it can be dropped and thereby lost. In addition, this descender heats up a lot during use. This is why many inventors have sought to improve this kind of device.
  • the objects of the present invention are to provide an improved descender over existing descenders.
  • the descender according to the invention will be insured against loss by clumsiness, in the sense that there will be no need to detach it from the harness to set it up; it will also present particularly studied forms so as to reduce friction.
  • Figure 1 we see the descender in its most complete embodiment. It presents in plan a body 1 which has approximately the shape of a pear whose tail is directed downwards.
  • the upper part of the body has a ring 2, while the lower part 23 is massive as seen in Figure 2.
  • the massive part 23 has two grooves 3 and 4 substantially parallel. These grooves 3 and 4 are located in a plane parallel to the plane of the ring 2.
  • the ring 2 has approximately the shape of a semicircle slightly flattened at its upper part. The purpose of this flattening is to separate the strands of rope well.
  • the grooves 3 and 4 arise on the massive part 23 at 11 and 12 and end in the same way on the other side of the massive part 23.
  • the massive part 23 still has a groove 13 delimiting a surface 24 comprising a protuberance 10.
  • the protuberance 10 in the embodiment shown came directly with the body 1. But in a variant the protuberance 10 could be attached to the surface 24 and fixed by a screw.
  • the descender In the lower part, in FIGS. 1 and 2, the descender has a hole 18 intended to receive a carabiner fixed to the harness of the mountaineer.
  • the safety device consists of a hollow cylindrical part 5 articulated on the solid part 23 along the axis 6 parallel to the plane of the ring 2.
  • the part on which the part 5 is articulated came with the body 1, but it could also be attached and fixed for example by means of a screw.
  • a piston 15 pushed towards the outside of the part 5 by a spring 17.
  • the piston has a small handle 14 allowing it to be maneuvered.
  • Figures 1 and 2 the safety device is shown in the locked position, that is to say that the piston is engaged in a hole in the protrusion 10, which prevents the part 5 from moving.
  • To unlock the device simply bring the handle 14 into the slot 16 by a light press followed by a rotation of 90 o .
  • the descender shown in FIGS. 1 and 2 also has two diametrically opposite T-shaped protrusions 7 on the ring 2 and an extension perpendicular to the plane of the ring having a hole 8.
  • FIG 6 the descender is shown in the rescue position for a minor casualty or for the descent or climb of the load.
  • the strands B1 and B2 being hooked to an anchor point, for example a peak, while the strands B3 and B4 representing the strands B1 and B2 after their passage in the descender go up towards the user who is at the point of anchoring.
  • the injured person or the load being fixed by a carabiner passed through hole 18.
  • the descender functioning as a pulley the two ropes moving in the same direction.
  • FIG. 7 there is shown a simplified embodiment not including the extension having the hole 8.
  • the descender is shown in the belay position of a second climber by a first climber in the relay.
  • the descender is fixed to an anchor 22, for example a piton, by a carabiner 21 passed through the hole 18.
  • the strands B3 and B4 go towards the second climber who is climbing, while the strands B1 and B2 which represent the strands B3 and B4 respectively after their passage in the descender are in the hand of the first climber who ensures.
  • the strings travel in the opposite direction.
  • the strand B2, B4 circulating in the groove 3 moves in the anticlockwise direction, while the strand B1, B3 moves in the clockwise direction. Note that the strands B3 and B4 are well separated which prevents twisting of the strings.
  • the descender in a simplified version without the extension comprising the hole 8 is shown in the momentary stop position during an abseiling.
  • the strands B1 and B2 go towards an anchor point, while the strands B3 and B4 which represent the strands B1 and B2 respectively after their passage in the descender hang in a vacuum.
  • the mountaineer being fixed to the descender by a carabiner passed through the hole 18.
  • Each strand B1 and B2 after passing through the grooves 3 and 4 is wound around a T-shaped protrusion so as to self-lock by tightening.
  • FIG. 3 there is shown the descender in the same embodiment as that of Figure 8 in an extended stop position during an abseiling, for example to plant a peak.
  • the strands B1 and B2 go towards an anchor point, while the strands B3 and B4 represent the strands B1 and B2 after their passage in the descender hanging in the vacuum.
  • the blocking is done as in the case described with reference to FIG. 8 by self-tightening by winding on the T-shaped protrusions 7 but in addition the strand B2, B4 comes to clamp the strand B1, B3 by tightening.
  • the body 1 of the descender can be produced by molding, for example, in synthetic material or in aluminum alloy.
