Abstract
A replaceable seal for water-tight and fire-resistant sliding doors, in particular for use on board ships and rigs, is roughly trapezoidal in shape having two opposite short sides, a long side therebetween, and a side of intermediate length opposite the long side. The intermediate length side of the seal is intended to lie against one of the arms of a Y-shaped support; one of the short sides of the seal is intended to lie against the upright of the Y-shaped support; the long side of the seat is intended to lie against a fastening device, preferably of a washer held with a bolt and nut; and the second short side forms the sealing surface of the seal for sealing against a door frame.
Claims5
In combination, a seal apparatus and a door leaf, the seal apparatus comprising a replaceable seal (10) mounted on a Y-shaped support (12) having an upright and two arms, said Y-shaped support being provided on a periphery of the door leaf;
