Definitions
- the present invention relates to a rappelling device, consisting of a slide piece working together with rope, which has a guide channel through which the rope can be passed and the slide piece or a carrying device for a belt or the like.
- the slider has an approximately U-shaped guide channel for receiving a rope and the point of engagement for the support device lying in the region of the axis of symmetry of the U-shaped guide channel is arranged in an area opposite the rope exit openings.
- a descender device of the aforementioned type is known from US-A-16 16 924.
- the guide channel in the subject of US-A-16 16 924 has an additional loop which serves to increase the sliding resistance of the guide channel.
- the present invention has for its object to improve a descender device of the generic type in such a way that its braking effect is sufficiently dependent on weight.
- the support device cooperates with a movable pressure piece, the pressure piece engaging in an opening running transversely to the guide channel and pressing the rope in the intended loaded condition.
- a further development of the invention provides that the carrying device is movably connected to the slider and can engage in the guide channel in such a way that, depending on the load, e.g. a person, braking a pressure piece acts on the rope.
- the slider is symmetrical and the rope ends are equipped with the same means for hooking or the like on a fixed bearing, after a person has been roped off, the rope can be pulled up with the slider and is easily changed, i.e. the free end of the rope located below is then connected to the fixed bearing and is immediately ready for use again.
- an opening 5 Opposite the free pipe ends 11, 12, preferably on an axis of symmetry A, is an opening 5 which receives a pressure piece 4.
- This pressure piece 4 is operatively connected to a support device 3.
- the opening 5 is dimensioned so that the pressure piece 4 can engage in the clear cross section of the guide channel 2 and thus can press on the rope 13.
- the pressure piece 4 in the area of the contact with the rope 13 has a shape adapted to the course of the guide channel 2.
- FIG. 4 shows the inner surface 16 of a slide piece 10a designed as a half-shell 17.
- Fig. 6 shows a possible form of use of the abseiling device.
- a cable end 131 opens at a stationary support point 21. Because the point of application of the support device 3 on the slide 10 lies opposite the cable outlet openings 7, the slide aligns in the manner shown in FIGS. 6-8.
- the other end of the rope 132 is guided sharply around the upper rounded edge 19, which leads to further friction between the slider and the rope.
- the person abseiling has the option of using little force, i.e. Traction to determine the sinking speed at the free end of the rope 132.
- this control of the sinking speed and of course also the stopping can be carried out by a person on the ground.
- the abseiling device can also be used in the reverse direction.
- the possibilities of use according to FIG. 7 u. 8 will be provided especially if the person to be abseiled is not able to do this himself.
- FIGS. 9 and 10 Another embodiment of the invention is shown in FIGS. 9 and 10.
- the representation is simplified to a great extent in order to simplify the clarity.
- the upper web 140 is not rigidly connected to the slider 100, but rather is displaceably mounted along the axis x-x.
- guidance is provided by tabs 141 connected to the web 140.
- a plate 142 connected laterally to the tube 90 is connected to the U-shaped tube 90.
- This plate is used in that the upper web 140, the free tube ends 11 u. 12 no longer stabilized, on the one hand the strength and on the other hand the guiding of the tabs 141 and thus the web 140.
- the guiding takes place by means of bolts 144, 145 penetrating the interior 143. These bolts are guided in elongated holes 146 in the plate 142. It should not be left unmentioned that when the overall construction is e.g. Metal or plastic casting is formed, differently designed guide means can be used without departing from the scope of the invention.
- a two-armed locking lever 147 is connected to the plate 142.
- One end of the lever 147 is connected to a corrugated brake pad 148, which can penetrate into the interior of the tube through an opening 149.
- the web 140 is pushed away from the slider 100 in the direction of the axis x-x by the action of a spring 153. This gives the person rappelling or the assistant the opportunity to stop the rappelling process.
- the lever 147 or the brake pad 148 is pressed against the rope at an acute angle and the rope is prevented from sliding in the direction of the arrow 152. Only when the person abseiling or the auxiliary person pulls on the free end of the rope 151 is the effect of the brake pad 148 canceled, because the web 140 and the tabs 141 are moved against the action of the spring 153 in the direction of the sliding piece 100.
- a bolt 144 connected with tabs 141 penetrates an elongated hole 154 in the lever 147.
- the elongated hole 154 is arranged in such a way that the lever 147 undergoes such a rotation that the brake pad 148 moves away from the cable.
- a further lever 147 a is shown in dashed lines. This is a mirror image in the manner described above in the abseiling device.
- the dashed representation is intended to provide a better overview.
- the device is equipped with two levers because, as described above, the abseiling device according to the invention is symmetrical and can be operated in both directions.
