Abstract:
1. An apparatus for holding transport curtains in place comprising: a lower frame; wheels operatively attached to the frame for permitting the lower frame to move over a surface of a road; a floor attached to the lower frame; an upper frame operatively attached to the lower frame; a track disposed on the upper frame; a roof operatively attached to the upper frame; a curtain operatively attached to the upper and lower frame for selectively providing a barrier to access to the floor in a first position of the curtain and providing access to the floor in another position of the curtain; a trolley wheel assembly disposed on the track of the upper frame to permit the trolley wheel assembly to move along the track at times; a first post member pivotally attached at the top thereof along a first substantially horizontal axis to the trolley wheel assembly, said first post having a bottom end; a second post member pivotally attached to the first post member along a second substantially horizontal axis at a first end of the second post member, the second post member having a second end; the second post member having a first pivotal position in alignment with the first post member and a second pivotal position pivoted away from and therefore not in alignment with the first post member; a dampening cylinder having a first end pivotally attached to the first post member and a second end pivotally attached to the second post member for preventing the first and second members from pivoting from the first to the second pivotal position too quickly; and a locking mechanism operatively attached to at least one of the first and second post members for selectively holding the first and second post members in the first position thereof.
