Definitions

  • the present invention is therefore an object of the invention to provide a security device for securing a person on a rope, which can be used ideally in high ropes gardens and therefore on the one hand must be easy to use and on the other hand provides a high level of security for the person to be secured.
  • the invention is based on the general idea to provide a safety device for securing a person to a rope, which has a substantially C-shaped, rigid body, so that the securing device is easily hooked into the safety rope over a laterally arranged on this body opening portion , wherein at the same time a self-locking locking mechanism is provided, which is on the one hand to operate and on the other hand in the locked state, the laterally arranged on the body opening portion closes and thereby fixes the safety device inextricably on the rope.
  • a self-locking locking mechanism is provided, which is on the one hand to operate and on the other hand in the locked state, the laterally arranged on the body opening portion closes and thereby fixes the safety device inextricably on the rope.
  • the C-shaped body at least one pulley is rotatably mounted, which rolls on or on the rope, in particular a safety rope, during operation of the securing device.
  • At least two rollers are provided, through which a jam-free method of securing means along the rope can be effected.
  • the at least one role is designed extremely smooth.
  • the securing mechanism on a backup role which is moved when locking on a side opposite the pulleys against the rope, so that with fully locked securing mechanism on the one hand, the rope between the / the pulley (s) and the backup roller fixed and on the other hand, the opening portion the backup roll is closed.
  • An accidental suspension of the safety device from the rope is thus effectively excluded, whereby the safety of the safety device to the person securing can be guaranteed to a particularly high degree.
  • the safety device according to the invention is - as mentioned above - to operate with only one hand and at the same time with respect to their total weight so light that they are concerned for an application in a climbing or high ropes course, which usually only lay people dealing with the safety device, easily suitable. Due to the special shape of the safety device, a pinching of the fingers between the safety device and the cable is avoided during hooking into the rope, which occurs again and again in existing systems, especially when laymen operate them.
  • the securing mechanism which is preferably biased by a spring means in its locked state, on the other hand, a correspondingly high security need or security feeling of a layman, who usually has rarely to do with such safety devices are met. This is particularly important for the acceptance in, almost exclusively by lay people attended, high ropes gardens of crucial importance.
  • a center of gravity of the securing device lies in the region of the arm protruding from the C-shaped body, so that the securing device in the unloaded state with the arm pointing downwards hangs vertically on the rope and is thus always optimally positioned (cable pulley).
  • arm below As a result, in the case of horizontal and obliquely upward or downward travel, the securing device can always optimally run along the cable without getting caught. The user can thereby focus on walking the stations and is not disturbed in his freedom of movement.
  • the safety device according to the invention is always stable in position, namely with the arm down, fixed to the rope, with a one-handed operation, so loosening or securing the securing device from / to the rope is possible.
  • Another advantage of the C-shaped arm protruding arm is also that the user when driving on a so-called. Zipline, has the ability to grip the protruding arm of the safety device with one hand, without risk to run the hand to the rope or between safety device and rope (danger of injury). This makes it possible for the user to stabilize his body position when driving on a zip line, so that an unintentional rotation about the body axis of the user can be prevented.
  • a pushable unlocking lever is provided with a locking slide, which must be moved to release the unlocking lever against the rope and thus usually against gravity and formed is that it is fixed in locking device hanging on the rope due to gravity in a lock-unlocking position.
  • the protruding from the C-shaped body of the safety device arm is dimensioned so that the center of gravity of the safety device is located in this arm, so that in a hanging on the rope safety device, the arm usually shows vertically downwards. This is also for gripping for a person operating the safety device, particularly favorable.
  • At least one holding opening is provided on the C-shaped body, to which, for example, a safety rope or a pull rope can be suspended.
  • a further, redundant securing of the securing device can thus be achieved by, for example, securing a securing cable likewise connected to the rope to the securing device.
  • a holding opening which may be formed, for example, as an eyelet, even for a rescue, in which one, for example, unconscious, person hanging on the rope and from Rescue workers must be recovered.
  • the rescue forces along the rope can get to the person injured and in the retaining opening of the safety device of the accident victim, attach one end of a traction cable, so that the accident victim can then be pulled with this traction cable to a more accessible rescue location.
  • a holding opening can also be used for other attachments.
  • a braking device is provided on the securing device, by means of which a relative speed of the securing device with respect to the rope is delayable.
  • a braking device allows a departure with the safety device according to the invention along a non-horizontal rope, after which, depending on the slope of the rope, the braking device is used to throttle the departure speed.
  • the braking device can be operated manually, for example, or depending on the speed itself trigger, so that a predetermined maximum speed is not exceeded due to the existing braking device. As a result, a particularly safe departure of the person to be secured on the rope is possible without fear that this gets too high a speed due to the inclination of the rope.
  • a securing device 1 for securing a person not shown on a rope 2, a substantially C-shaped, rigid body 3, in which two pulleys 4 and 5 are rotatably mounted (see also Fig. 4 ), which roll on or on the rope 2 during operation of the securing device 1.
  • two pulleys 4 and 5 are rotatably mounted (see also Fig. 4 ), which roll on or on the rope 2 during operation of the securing device 1.
  • FIGS. 1 to 5 is in each case exemplarily shown the preferred embodiment with two pulleys 4,5 and described.
  • the body 3 is usually made of a solid material, for example of metal.
  • the two, in the body 3, rotatably mounted pulleys 4,5, are also formed for example of metal, or of a durable plastic and have a concave and adapted to an outer contour of the rope 2 tread.
  • a protruding arm 7 is further provided, which is for example formed integrally with the body 3 or at least firmly connected thereto.
  • a lockable locking mechanism 8 is arranged, which moves when locking a backup roller 9 on one of the pulleys 4 and 5 opposite side against the cable 2 (see. Fig. 2 ).
  • the rope 2 between the pulleys 4 and 5 and the pulley 9 is fixed and on the other hand, the opening portion 6 closed by the backup roller 9, so that accidental release of the security device 1 can be safely excluded from the rope 2.
  • the securing mechanism 8 is via at least one spring device 10, according to the in the Fig. 1 to 5 illustrated safety device 1 via two spring devices 10 and 10 ', biased in its locked state. Can unlock the locking mechanism 8 by pressing an unlocking lever 11 against the forces exerted by the spring means 10 and 10 '.
  • a locking slide 13 is provided on the unlocking lever 11, which must be moved to release the unlocking lever 11 against the rope 2 and usually against gravity.
  • the arm 7 protruding from the body 3 fixes the center of gravity of the securing device 1 in such a way that, when the safety device 1 is suspended from the cable 2 in the unloaded state, it usually points vertically downwards (cf. Fig. 2 ).
  • the user by the arm 7 to stabilize his body position during a descent along an inclined rope 2 and thus to prevent accidental rotation about the body axis of the user.
  • the locking slide 13 To release the unlocking lever 11, thus the locking slide 13 must be moved upwards, so that it is usually fixed by the force of gravity in one, the release lever 11 blocking position in the cable 2 hanging and unloaded security device 1.
  • the arm 7 and the release lever 11 and the locking slide 13, are designed so that they can be operated with one hand, whereby the handling of the security device 1 according to the invention is significantly simplified.
  • Fig. 3a and 3b so jump according to the Fig. 3a a locking contour 14 into the eye, via which the locking slide 13 for unlocking the securing device 1, as shown in FIG Fig. 3a shown must first be moved.
  • a braking device not shown, is arranged on the securing device 1, by means of which a relative speed of the securing device 1 can be delayed with respect to the cable 2, whereby in particular cable runs on diagonally tensioned cables 2 are possible.
  • a braking device may be manually operable, for example, or automatically brake, for example by means of a centrifugal clutch, if a predefined rolling speed is reached or exceeded.
  • the securing device 1 Since dealing with such security devices 1, especially in the field of high ropes gardens, usually done by laymen, the securing device 1 according to the invention should at least complicate a pinching of objects and / or limbs between the rope 2 on the one hand and the pulleys 4 and 5 on the other hand. For this reason, the C-shaped body 3 is longitudinally of the rope 2 on the pulleys 4 and 5, so that usually trapping of objects or limbs is not possible.
  • a connection between the person to be secured and the securing device 1 can take place via a not shown safety rope or securing band, which is connected via a retaining opening 21 fixed to the securing device 1.
  • the safety device 1 With the safety device 1 according to the invention it is thus possible for the first time to provide a safety device 1 which is particularly suitable for ropes, which on the one hand is also easy to operate by laymen and on the other hand ensures adequate protection of the persons to be secured via the safety device 1 despite the ease of operation.
  • the safety device according to the invention has the great advantage that it is much lighter and thus easier to handle, while it is designed much more robust compared to conventional, used for mountaineering, safety devices, and thus Even the increased load requirements in high ropes gardens for a long time withstands.
