Positioning thermoplastics machine housing on parallel upright flanges - using gripping claws integrally moulded to the housing

摘要

Arrangement for fastening a thermoplastics machine, appliance or appts. casing upon a "U"-profiled rail or bar which is gripped by claw-like protrusions at that side of the casing where it is to be fastened, is claimed. The protrusions form an integral feature of the casing. One of the protrusions gripping one of the "legs" of the "U" has inherent spring-like resiliency. Both protrusions are actually extensions of the sidewalls of the casing. The resilient protrusion sits at the end of a tongue formed by two incisions in the wall of the casing.
