ROLLER DOORS

摘要

A roller door having a seal means (30) which is attached to the door shutter (22) at a location such that when the door is in its closed condition, the seal extends from the face of the door and extends outwardly therefrom and contacts the door sill (13) and, when the door is opened, the seal means (30) is caused to be located between the portion of the shutter to which it is connected and the portion of the shutter which lies directly thereover, the seal means is of such a form that when so located it has little effect on the form of the rolled shutter. The embodiment shows the seal means being formed of an extrusion of a resilient material which, when unconstrained has a substantial depth extending outwardly of the door but which can reduce to a minimal depth when pressure is applied thereto. The seal means (30) may have extensions along each side which can be received in recesses on the face of the shutter.
