Appeal No. 2005-0322
Application No. 10/431,268
Representative claim 1 reads as follows:
1. An injection molding machine, comprising:
a stationary platen;
a movable platen constructed for movement relative to the
stationary platen;
at least one tie bar for tension-proof connection of the
stationary and movable platens; and
a traction transmitting securing device including a securing
element, disposed on a rear side of one of the platens, for
interacting with the tie bar within an engagement zone, wherein
one of the securing element and the tie bar has a number of
projections in axial spaced-apart relationship, and the other one
of the securing element and the tie bar has a number of recesses
disposed in axial spaced-apart relationship and engageable by the
projections to establish a form-fitting connection, wherein the
projections and the recesses are pressed together when exposed to
a tensile stress and interlock at an axial clearance which
increases along the engagement zone in axial direction
corresponding to the tensile stress of the tie bar.
