Definitions

  • the present invention relates to a roadblock according to the preamble of claim 1.
  • Roadblocks of this type have the disadvantage that either the spikes of steel belt tires traveling over them can be put on the belt ineffectively if their anchoring on the plate is too weak or that the lock (after the spike has been inserted) is carried away by the tire and is inoperative for subsequent vehicles if the mandrel is too tightly connected to the plate.
  • the object of the present invention is to improve a roadblock of the type mentioned in such a way that the mandrels also withstand steel belt tires without the barrier being carried along by the tire after the mandrel has been retracted.
  • the spikes are fastened to the plate in a sufficiently stable manner and suddenly detach from it when the tire itself rolls onto the plate.
  • One of the legs is bent in the direction of travel. After using the roadblock, it is therefore possible to replace the torn out thorns by placing a new thorn in the socket and using pliers to press the two legs against the thorn foot be clamped.
  • the embodiment according to claim 2 also has the advantage that a destroyed socket can be replaced by a new one by loosening the screw.
  • the embodiment according to claim 3 prevents ice formation in the venting channel by the relaxing air, as a result of which the vehicle to be stopped can be stopped more quickly.
  • a roadblock according to the invention has a flexible band 1 with end handles 2. These are used to handle the lock when laying out and clearing away. At regular intervals, 2 rigid plates 3 are attached to the belt 1 between the handles. Each plate 3 carries two mandrels 4. These are perpendicular to the plates 2. Due to the flexibility of the belt, the roadblock can be stowed in a small box like an ammunition belt and can therefore be stored and transported in a space-saving manner.
  • the mandrel 4 (FIG. 2) has a cylindrical base 5, a cylindrical shaft 6 and a conical section 7 forming the tip.
  • the mandrel is provided with a hollow core 8 open in the longitudinal direction.
  • a slot 9 on the side of the mandrel cuts the hollow core 8, as a result of which it is also open to the outside at its front end.
  • the apex angle 10 of the mandrel tip is less than 35 °, preferably 25 to 30 °.
  • the largest diameter of shaft 6 and section 7 is less than 8 mm.
  • the entire length of the mandrel can vary between 25 mm and 60 mm.
  • the conical section 7 has a region 12 with a barb structure. For this purpose, shoulders 13 and 14 undercut by recesses are formed in the cone jacket.
  • the size of the distance 11 depends on the size of the apex angle 10. It is inversely proportional to this. It must be chosen so large or small that the spike penetrates from the tire over the shoulder 13 when it is first run over. As the tire continues to rotate, the mandrel is fully retracted and not flung away. The size of the distance 11 is calculated according to the empirical formula:
  • the distance 11 may not exceed 8 mm and for an apex angle 20 ° not more than 14 mm.
  • the mandrel 4 is held in a version 15. This consists of a base plate 17 protruding from the U-shaped two legs 18 upwards. A central bore 16 passes through the base plate 17. The legs 18 have a ring-shaped cross-section and lie against the foot 5 of the mandrel 4.
  • the plate 3 consists of a carrier plate 19 and a counter plate 20, between which the band 1 is firmly clamped. Coaxially with the mandrel 3 or the bore 16, the plates 19, 20 and the band 1 are penetrated by a bore 21. A self-tapping screw 22 is screwed into the bore 16 from below through the bore 21. It forms a firm connection between the plates 19, 20, the band 1 and the socket 5. The mandrel 1 is clamped with its foot 5 between the legs 18 of the socket 15.
  • the legs 18 on the socket 15 are dimensioned such that their greatest width "b" is roughly equal to their smallest distance "a". With a width "b" of 9 mm the distance "a” is preferably 6 to 8 mm. As a result, the legs 18 have sufficient stability to clamp the mandrel 4. But are they flexible enough when a car tire runs over the spike to bend outwards and release the spike.
  • the sockets 15 are preferably attached to the belt 1 in such a way that the legs 18 are oriented transversely to the direction of travel (arrow P in FIG. 3). During the penetration of the mandrel into a car tire, the mandrel is initially slightly inclined in the direction of travel of the car, the plate 3 lifting slightly. As soon as the ascending car tire hits the plate, it is folded down onto the street and the leg 18 lying in the direction of travel is bent over and releases the foot of the mandrel.
  • the hollow core 8 has a larger diameter in the foot 5 than in the shaft 6 and opens out with a conical widening outwards. This results in an increasing diameter towards the rear in order to gradually relax the air emerging from a tire. This prevents temporary ice formation and a delay in air leakage.
