ABSTRACT:
An impact resistant assembly is provided which comprises a longitudinal, molded shaft composed of a thermoplastic material and having screw threads at one end thereof and a planar head plate at the opposite end. Adjacent to the head plate is an upper cylindrical shaft section upon which is securely positioned a metal collar, which is preferably provided with an enlarged metal rim, to support the head plate and adjacent cylindrical shaft section against substantial deformation during the subsequent molding thereon of a resilient, head member which is formed from a thermosetting material. It has been found that the combination of the planar head plate and the adjacent metal collar is essential to form the desired impact resistant assembly having the resilient, impact resistant head member molded thereon. The impact resistant assemblies of this invention are particularly suited for use in bowling alley backstops which are subjected to repeated and severe direct impacts by bowling balls of high mass.
