Hohlpfosten, insbesondere Straßenleitpfosten, und Verfahren zu seiner Herstellung

摘要

A hollow plastic break-away post for street markers and the like, where an extruded plastic shaft with integrally extruded interior stiffening members are butt-welded to a post base which includes several locking noses on its cylindrical anchoring portion. The post base fits into a fixed anchoring socket and is lockable therein in a bayonet-type lock, the base being capable of yielding elastically to permit the locking noses to snap loose for a damage-free break-away of the post under impact. The locking noses of the base are reinforced and protected against wear by metallic nose inserts which are imbedded in the plastic material.
