Definitions

  • the present invention relates to a device for retardation. Furthermore, defines relates to application thereof on a roof or in a system for prevention of falling down from the roof.
  • Such a system comprises for example fixed rings that are attached on a roof and to which a lifeline can be fastened that may be fastened to the clothing, belt or trapeze of a roofer.
  • An advantage of such systems is that these may prevent that the roofer falls towards the earth when a falling incident takes place.
  • such a system has an important disadvantage that a falling person maybe stopped abruptly during falling towards the earth. This after breaking off the fall leads to high G. forces and therefore to injuries to the body.
  • a solution that has been thought of in the past is the application of a vertically resilient mast that is placed on top of the roof and that may absorb a part of the shock.
  • Several of such devices would be required on a roof, for one reason while most times several people are working on a roof simultaneously and for another reason while the lines should not be too long or should not get entangled with other objects on the roof of the furthermore, such devices are large objects that are costly to provide and that require additional preparations, such as fastening means on the roof.
  • the present invention provides a device for deceleration for securing of a person against injuries caused by falling, the device comprising:
  • - a house comprising a deceleration channel, - a lead through opening that is arranged at one end of the deceleration channel for leading deceleration member through it,
  • deceleration member that is of an elongate shape and that is arranged in the deceleration channel, in which the deceleration member is subject to friction in the deceleration channel.
  • An advantage of such a deceleration device is that a deceleration of a fall may result by means of the fric- tion caused by the deceleration channel to the deceleration member that is present in the house while the deceleration member is pulled through and wherein the fall deceleration results in a substantial diminishing of the potential G. forces. Because of this, injuries to the body will be diminished.
  • a further advantage of the internal deceleration channel is that the deceleration defined may be embodied in a compact fashion and death because of this no additional facilities are needed on the roof.
  • the deceleration channel of the deceleration device has at least partially a substantially spiralled shape.
  • This spiralled shape provides for the possibility of creating a compact deceleration channel while a sufficient deceleration is achieved.
  • the deceleration device may be built in a compact manner and fit on a roof in a simple manner.
  • the deceleration channel comprises narrow parts or indentations at least as seen in a cross-section.
  • the deceleration member comprises a, in cross-section, protruding element for providing a further retardation. In contact with the wall of the channel, friction is provided which strengthens the retardation. The forcefulness of the deceleration may be set in a predictable manner.
  • a practically important advantage of these embodiments is that an initial threshold setting may be pro- vided. Because of this, it may be prevented that the deceleration member would be pulled out of the channel without a real fall happening, which would diminish the effectiveness of the device.
  • a threshold setting may be provided by means of e.g. a narrowing of the channel with a protrusion of the deceleration member or a combination thereof.
  • a coupling device that may be arranged to the deceleration member for coupling thereto to a belt or a trapeze for coupling of a person to the deceleration device in a safe manner is an advantageous way to practically use the device while at the same time a high level of user friendliness is provided.

  • a shape treatment of a part of the house such as deep drawing, molding, injection mold- ing, rolling etc.
  • the decelera- tion channel around the lead through opening is shaped in such a manner that the deceleration channel moves away from the heat through the opening relatively quickly in a radial fashion as compared to the spiral shape of the deceleration channel relatively far away from the lead .
  • An advantage of this feature is that the deceleration member may be guided in such a manner that the deceleration member may be guided in a predictable manner and by means of a wide curve. Such a feature helps preventing a nod which allows for a hide reliability, even when the device re- sides on the roof for a long time.
  • a further feature for providing a high lifetime is the application of a filler means in the channel, such as a foam, preferably comprising, those cells, and or a water repellent component.
  • a filler means in the channel such as a foam, preferably comprising, those cells, and or a water repellent component.
  • the closedness of the cells provides for a good resistance against intruding humidity.

  • a covering member will during practical use being relatively often embodied as a role of bitumen mate ⁇ rial that is known in itself for providing weather resistance to roofs.
  • An advantage of providing an opening therein is that because of this, the securing device may be mounted in a straightforward manner. It is to be noticed, that irregularities in itself and especially openings in such bitumen material are absolutely undesired and need to be prevented. Because of this, a covering member according to the present invention may be recognized in a straightforward manner.
  • a further advantage of such a covering member is that by means of the reinforcement member and a relatively high pull resistance is obtained as compared to in itself known bitumen material which enables a secure anchoring of the engaging member of the securing device at the under side of the reinforced bitumen roll.
