Reinforcing or restraining strap or gusset system for rear wall member of bulk material cargo container liner

摘要

An external reinforcing strap system for a bulk material cargo container liner comprises a plurality of vertically spaced, horizontally oriented reinforcing straps, or a plurality of horizontally spaced, vertically oriented reinforcing straps and a plurality of vertically spaced, horizontally oriented reinforcing straps, to have their tension levels individually adjusted in an independent manner in order to provide selected sections of the external reinforcing strapping system with requisites amount of tension. In addition, a substantially U-shaped reinforcing gusset system is also disclosed which provides the necessary reinforcement for the rear wall member of the bulk material cargo container liner but with a simplified structure effectively eliminating the aforenoted strapping system.

主权项

1. A reinforcing strapping system for use in connection with the rear end wall member of a bulk material cargo container liner in order to prevent the out-ward bulging of the rear end wall member of the bulk material cargo container liner, comprising:
a plurality of vertically spaced, horizontally oriented reinforcing straps; a plurality of horizontally spaced, vertically oriented reinforcing straps crossing said plurality of horizontally oriented reinforcing straps so as to form with said plurality of horizontally oriented reinforcing straps a grid-type arrangement which comprises a plurality of intersection points defined between said plurality of vertically oriented reinforcing straps and said plurality of horizontally oriented reinforcing straps at locations at which said plurality of horizontally oriented reinforcing straps cross said plurality of vertically oriented reinforcing straps; and a plurality of tubular sleeve members through which said plurality of vertically oriented reinforcing straps are respectively and individually movably disposed, wherein said plurality of tubular sleeve members are fixedly attached to the rear end wall member of the bulk material cargo container liner substantially along their entire length, except at said plurality of intersection points defined between said plurality of vertically oriented reinforcing straps and said plurality of horizontally oriented reinforcing straps at said locations at which said plurality of horizontally oriented reinforcing straps cross said plurality of vertically oriented reinforcing straps, so as to define unattached portions of said tubular sleeve members which define a plurality of passageways through which said plurality of horizontally oriented reinforcing straps can respectively and individually pass, whereby said plurality of horizontally oriented reinforcing straps and said plurality of vertically oriented reinforcing straps are freely movable with respect to each other even at said plurality of intersection points forming said grid-type arrangement of said plurality of horizontally oriented reinforcing straps and said plurality of vertically oriented reinforcing straps.
