Definitions

  • the invention relates to a beacon foot joint with a fork, between the arms a shaft of the beacon is pivotally mounted and a locking device, which removably holds the shaft in the upright position.
  • the beacon sheet indicates guidance and warning beacons for securing road construction sites usually at the bottom of a shaft that fits into a hole Footplate made of recycled material is inserted. If the beacon sheet from one Vehicle is started, it should fold over without the footplate strikes so that the occurrence of major personal injury or property damage is avoided becomes. This folding of the beacon sheet can be done by a predetermined breaking point reach or kink, but is preferably for this purpose specially designed beacon foot joint is provided.
  • a beacon ankle of the type mentioned, but not specifically for Beacons, but generally for traffic signs, are described in DE 197 20 084 A1.
  • the locking device is by a Pin formed, which is offset to the pivot axis by the arms of the fork and extends through the shaft and is sheared off when the beacon is approached. To however, this shearing only occurs when the load is jerky, when the beacon is approached at a relatively high speed. Become frequent the beacons on road construction sites, however, from construction vehicles with relative approached at low speed. In this case, the impact energy is sufficient not shear off the pin, and instead the shaft or one of these The shaft and the beacon tube stiffening the beacon blade are bent or kinked, so that the beacon becomes unusable.
  • a beacon foot joint in which a Shoe into which the shaft of the beacon can be inserted can be pivoted in a recess the footplate is stored.
  • the locking device is here by spring clips formed, which are attached to the footplate and with projections in engage corresponding recesses in the shoe.
  • this construction is relatively complex and requires a special adjustment of the footplate.
  • the object of the invention is to provide a beacon ankle that is constructive is simple in construction and yet with high reliability it is damage-free Turning the beacon sheet allows.
  • the resilient arms of the fork give way, and the projections give way Free the beacon so that the beacon is folded over. Because the resilient elements formed here directly by the arms of the fork, the joint has a total a very simple structure, and it can be manufactured inexpensively.
  • the shaft of the beacon can simply be inserted into the fork from above so that it is only through the projections formed on the arms is held.
  • the shaft is preferably held by a bolt, which is in a position offset from the projections in height through the arms of the fork and through the shaft and pulling it out prevents the shaft upwards and at the same time a defined joint axis forms.
  • the beacon sheet thus remains in the folded state the footplate connected so that the beacon blade even at high speed is not flung away and endangers people.
  • the fork is on a foot part trained, which can be inserted into the opening of the footplate.
  • This construction therefore does not require any special adjustment of the base plate, so that conventional foot plates that have a standardized insertion hole for the shaft of the Have beacons equipped with the beacon foot joint according to the invention.
  • the foot part is preferably inserted into a sleeve-shaped adapter is in turn locked in the opening of the footplate, and the locking of the The adapter is secured by the inserted foot section, as in the European one Patent application 01 124 005 of the applicant is described.
  • the lock is, for example, a bayonet lock reached. If at the beacon foot joint the shaft of the beacon blade is held by a bolt on the fork and thus on the foot part, so this bolt can be used to produce the lock Torque are transmitted from the beacon blade to the foot part.
  • the torque transmission can also be achieved that the shaft is designed as a square and the fork one to this Square forms a complementary receptacle for the shaft.
  • the projections that the locking device form, in pairs opposite each other on the arms of the fork be designed so that they encompass the shaft on all four edges.
  • the fork and the foot part can be combined in a particularly advantageous manner Be designed as a plastic injection molded part.
  • the beacon sheet 10 is a Blow mold made of plastic, which has a shaft 14 with a square at the lower end Has outer cross section, which is held in the beacon foot joint 12 is.
  • the shaft 14 is formed by a beacon tube 16 designed as a square and stiffened the beacon sheet 10.
  • the beacon foot joint 12 has the shape of a fork 18, the base leg is formed by a circular flange 20, two of which Raise arms 22.
  • the arms 22 lie flat on opposite sides of the Shaft 14 and each have on the inner surfaces facing each other two strip-shaped vertical projections 24 on the shaft 14 at its four Grasp edges.
  • the arms 22 are formed as a hollow body made of plastic and are each below the projections 24 to an elastically flexible Web 26 constricted so that the upper ones provided with the projections 24 Allow the ends of the arms 22 to bend apart elastically.
  • the webs 26 are limited by semicircular recesses in the transverse direction 28 in the inner surfaces of the arms and through them opposite U-shaped recesses 30 in the outer surfaces.
  • the two arms 22 are connected by a bolt 32, which extends through the shaft 14 and the beacon tube 16 and an articulated axis of the beacon foot joint.
  • the fork 18 is molded in one piece onto a plastic foot part 34.
  • the Foot part 34 has the shape of a cylindrical sleeve that passes through at the upper end the flange 20 is completed and several on its peripheral surface Bayonet projections 36 carries.
  • At the bottom of the foot 34 has resilient Locking cams 38, which are incorporated into the wall of the sleeve.
  • FIG. 2 illustrates the attachment of the beacon ankle 12 to a footplate 40.
  • the base plate 40 has an opening 42 with a square cross section, into which an adapter 44 is inserted from above.
  • the adapter 44 has one on the cross section of the opening 42 adapted square outer cross section and has a flange 46 at the upper end which is on the top of the footplate 40 rests.
  • the adapter 44 has locking claws 48 which are attached lock the bottom of the footplate.
  • the inner cross section of the adapter 44 is adapted to the outer cross section of the cylindrical foot part 34, so that the foot part 34 can be inserted into the adapter from above.
  • In the peripheral wall of the adapter 44 are locking slots 50 for the bayonet projections 36 recessed.
  • the beacon sheet 10 initially held in a position rotated by 45 ° with respect to FIG that the bayonet projections 36 point to the corners of the square opening 42.
  • the foot part 34 is then inserted into the opening of the adapter 44 from above.
  • the locking cams 38 spring back inwards so that the foot part 34 continues to introduce.
  • the bayonet projections 36 enter vertical grooves a, which are formed in the inner surface of the adapter 44 and at the bottom End in the locking slots 50. If the bayonet projections 36 butt against the lower edges of the locking slots 50, that can Do not insert foot section 34 deeper.
  • the beacon sheet is then moved around its vertical Center axis rotated by 45 ° into the position shown in Figure 2.
  • the torque is thereby by the bolt 32 and by the rigid lower regions of the Arms 22 from the shaft 14 onto the beacon ankle 12 and the foot part 34 transmitted without the upper ends of the arms 22 being significantly loaded.
  • the bayonet projections 36 enter the Locking slots 50, so that the foot part 34 in the vertical direction in the Adapter is locked.
  • the locking cams 38 fall into slots 52 of the adapter.
  • the lower The end of the foot part 34 then supports the locking claws 48 from the inside, so that also the latching of the adapter 44 is secured in the opening of the footplate 40.
  • the flange 20 of the beacon foot joint 12 is now a short distance above of the flange 46 of the adapter 44 and prevents the ingress of dirt into the adapter.
  • the arms 22 and the articulation axis of the beacon foot joint are located thus above the base plate 40.
  • the shaft 14 and the beacon tube 16 have a certain ground clearance within the fork 18 so that they are Allow to pivot about the hinge axis without hitting the flange 20.
  • FIG. 4 shows an external view of one of the arms 22, which is a hollow body is formed and stiffened by ribs 54, 56. Rib 56 defines one circular recess in which a nut 58, which secures the bolt 32, protected is included. In the other arm 22, which cannot be seen in FIG. 4 the head of the bolt 32 is received in a corresponding manner.
  • Figure 5 shows how the shaft 14 of the beacon blade is held by the projections 24 becomes.
  • the vertical distance of the protrusions 24 from the central axis of the bolt 32 is larger than half the width of the shaft 14. If the shaft 14 in the horizontal position according to Figure 6 was flipped, the projections are therefore 24 above the shaft 14 so that the arms 22 are in the neutral position can spring back. In this way, material fatigue is avoided.
  • the shaft 14 can be temporarily bent apart Swing arms 22 back into the upright position, where he passes through again the protrusions 24 are secured so that the beacon is ready for use again.
