Automatic Door Bottom With Intumescent Extended Drop
An automatic door bottom to seal a gap between a door bottom and a door sill and includes a drop bar assembly with a seal element is held in a channel mounted on a door. The automatic door bottom also includes a spring-loaded, slidable pushrod assembly which, upon closure of the door, forces the seal element out of the channel and into contact with the door sill. Upon door opening, the slidable pushrod assembly is released and retracts the seal element back into the channel. Further included within the channel is an intumescent material also communicating with the drop bar assembly, where, when exposed to heat or high temperature, forcefully expands within the channel to force the seal element out of the channel and into sealable contact with the door sill, thereby preventing fire expansion through a gap around the door.
