Patent ID: 8316584

Claim:
A fire safety-structural element for doors or windows, comprising: at least one fire safety glass unit defining a plane and serving as a door or window leaf, the fire safety glass unit being insertable into an opening with a frame in a building to close off the opening; a telescoping element between at least one side edge of the fire safety glass unit and a fixed element of the frame and adjacent the side edge, the telescoping element comprising a first stationary part, and a resilient second, displaceable part; a free interspace being formed between the two parts of the telescoping element and in each of two outer regions of the free interspace, one elastic element, each elastic element being a tape of a material foaming under heat impact, the two tapes being disposed transversely to the plane of the fire safety glass unit with a free spacing with respect to one another; and a joint gap being formed between the resilient second part of the telescoping element and the fire safety glass unit, and, in the event of fire, the resilient second part is displaceable relative to the first part so that the joint gap is closed off by direct contact between the resilient second part of the telescoping element and the fire safety glass unit.
