| 96 | Head curtains for dock shelters or dock seals | US12821973 | 2010-06-23 | US08327587B2 | 2012-12-11 | Charles Digmann; Gary Borgerding; Timothy J. Schmidt |
| Head curtains for dock shelters or dock seals are disclosed. An example head curtain assembly for a vehicle loading dock includes a retractable curtain stiffened by a resiliently compressible foam panel that is more flexible about a horizontal axis than about a vertical axis. The difference in directional flexibility can be created by sewing the foam panel to a pliable cover using a series of parallel horizontal thread lines. The thread lines create in the foam a series of compressed indentations that run horizontally across the curtain so that the curtain tends to bend more easily along those lines. The relative stiffness in the horizontal direction enables the curtain to exert an appreciable sealing force against two lateral dock seal members, and the vertical flexibility makes the curtain easy to retract to accommodate vehicles of various heights. Touch-and-hold fasteners make many of the individual components of the head curtain readily replaceable. | ||||||
