Definitions

  • the present invention concerns a means as defined in the preamble to claim l.
  • This means comprises an elongated net which has been arranged to grab hold of the moving vehicle, which net comprises a head rope and a foot rope.
  • the means comprise a pair of masts, which masts have been set up at both ends of the net and have been arranged to keep the net tensioned between the masts.
  • the means comprise brake members, which have been connected between the net and the substantially rigid support points to both net ends and which brake members have been arranged to absorb the kinetic energy of the moving vehicle.
  • the means comprise stationary parked anchoring vehicles, which have been arranged to anchor stationary the support points of the brake members.
  • a towing hook is required in the anchor vehicle in order to attach the brake members.
  • a towing hook or a towing loop is however not in certain countries a standard accessory of a police car, so the anchor vehicles do not always provide proper attachment points for brake members.
  • the known mast constructions for hanging up the net are unpractical and clumsy with their long support legs.
  • the unconnected masts may fly uncontrolled and harm the persons or the vehicles in the surrounding during the arresting.
  • the masts may also get attached to the net and get pressed against the body of the arrested vehicle thus causing damages to it.
  • An additional problem is, that the masts may get damaged in the above mentioned situations.
  • the object of the invention is to eliminate the drawbacks mentioned above.
  • Especially the object of the invention is to present a means for stopping a land vehicle, which is fast to deploy for use and which is suitable for use also with such anchor vehicles, with are not supplied with towing loop or such ready attachment points.
  • the object of the invention is additionally to present a means, where both the mast and the brake members can be supported with the aid of the anchor vehicle.
  • the object of the invention is to present a means, which is completely safe for the persons both in the vehicle to be stopped and in the surrounding of the arresting site. Furthermore, the object of the invention is to present a means, which does not harm the anchor vehicle or the vehicle to be stopped.
  • the object of the invention is to present a means, which enables a complete "surprise attack” towards the vehicle to be stopped, ie. an arrest without any advance warning.
  • the means of the invention for slowing down and/or stopping the motion of a land vehicle is characterized by that which has been stated in claim l.
  • the means comprise a support body, which supports to a wheel of the anchor vehicle; and a mast and/or the support point of the brake member has been joined to the support body.

It is possible to support only the mast to the support body, if the anchor vehicle has some other suitable attachment point, e.g. a towing hook for the brake members.
  • the support body can be constructed only for supporting of the mast, in which case the structure can be made very lightweight. If the anchor vehicle has not a suitable attachment point for brake members, one can also attach the brake members to the support body, in which case naturally the support body construction becomes heavier.
  • the masts have been arranged to pivot upon the support body between the substantially horizontal downlaying position and the substantially vertical upraised position; that into the system belong a force member to turn the mast between the downlaying and the upraised position, and a locking device to lock the mast to the downlaying and/or the upraised position.

  • the support ' body includes grab handles, which have been arranged to support to the wheel periphery surface and sides at least at three different points; and that intermediate distance between the grab handles is adjustable and can be fixed in order to adjust the attachment for different sizes of the wheels.
  • the attachment point of the'brake member locates substantially at the level of the wheel center; and that * the mast has been arranged to pivot upon a swivel, which locates within a distance from the attchment point and above it.
  • the pull force will be set to affect on the support body about at the level of the wheel center, the pull force will not tend to twist the grab handles loose from the wheel.
  • the pivoting point of the mast locates above the mentioned attachment point, the mast can not get mixed in with the opening process of the brake member.
  • the force member comprises a pull member', like a rod or a cable, to pull the mast up from its downlaying position and a gas generator fitted with an explosive charge in order to generate the pull into the pull member.
