Description

"Leichtstab" Fritz Becker,Bonn Die Erfindung betrifft einen Leichtstab der rohrförmig ist,beliebigen Querschnitt hat und aus glasfaserverstärktem Kunststoff besteht,dessen Glasfasern in der Rohrwand vornehmlich parallel zur Rohrachse verlau- fen und der im Innern Versteifungen hat,Er kann für sich allein,z.B! als Sportgerät wie Sprungstab oder z.B.als Pioniergerät wie begeh und befahrbare Planke,oder als Bauelement mit gleichen oder anderen Bauelementen zusammen z.B.für den Hau von Flugzeugen,Luftschiffen oder Zelt-und Hallenkonstruktionen u.ä.,eingesetzt werden. Er muss zu diesem Zweck besonders leicht sein und hohe Festigkeiten und EJmtizität aufweisen. Sprungstäbe aus glasfaserverstärktem Kunststoff sind bekannt.Sie be- stehen aus einem Rohr in dessen Wand die Glasfasern vornehmlich paral- lel zur Rohrachse verlaufen.Sie sind verhältnismässig dickwandig und daher schwer.Beim Bruch zersplittern sie in lanzenförrige spitze Split- ter und haben scho viele schwere Unfälle verursach-.
