The invention relates to a segmented lifting or folding gate, which is vertically movable and consists of a plurality of segments (1), adjacent segments (1) being pivotable relative to one another at their ends along horizontally extending pivot axes (2), comprising a door, which consists essentially of cases and a door leaf, the door leaf being composed of a plurality of door leaf segments (4), which are pivotable relative to one another and whose pivot axes (5) extend coaxially to the pivot axes of the gate segments (2), and wherein the door leaf extends to the floor (6) when the gate is closed, the door leaf or the case being provided with at least one opening (11), at least one sliding bolt (9) being arranged axially in the floor region of the case (10) or of the door leaf, so as to be horizontally displaceable in the main plane of the gate, and the sliding bolt (9) engaging in the opening (11) when the door is closed.
Segmented lifting or folding gate, which is vertically movable and consists of a plurality of segments, adjacent segments being pivotable relative to one another at their ends along horizontally extending pivot axes, comprising a door, which consists essentially of cases and a door leaf, the door leaf being composed of a plurality of door leaf segments, which are pivotable relative to one another and whose pivot axes extend coaxially to the pivot axes of the segments, characterised in that
Segmented sliding or folding gate according to one of the preceding claims, characterised in that the sliding bolts (9) are electromagnetically and/or hydraulically and/or pneumatically and/or mechanically moveable.
Segmented sliding or folding gate according to one of the preceding claims, characterised in that, in the lower edge region of the door leaf, one or more bolts (7) arranged vertically in the main plane of the gate are provided, which, when the door and the gate are closed, engage or engages in one or more openings (8) in the floor.
Segmented sliding or folding gate according to one of the preceding claims, characterised in that the length of the bolts (7, 9) corresponds to three to eight times their diameter.
Segmented sliding or folding gate according to one of the preceding claims, characterised in that, on the bottom edge of the gate, an electrical safety contact strip (3) is provided, and in particular the latter is in three parts.
Segmented sliding or folding gate according to one of the preceding claims, characterised in that a panic lock is mounted on the door.
Segmented sliding or folding gate according to one of the preceding claims, characterised in that the vertically arranged bolts (7) are displaceable and, like the rods (13) are in active connection with the door handle and/or the door lock.
Segmented sliding or folding gate according to one of the preceding claims, characterised in that the door leaf and/or the vertical cases (10) are provided with hook-like devices, the projections engaging on the vertical cases (10) and/or laterally on the door leaves.
Segmented sliding or folding gate according to one of the preceding claims, characterised in that, on both narrow sides in the lower region of the gate, there is mounted a pressure roller (17), which, as the door is being closed, runs on a centring or locking curve (18), which is mounted in the lower part of the gate case.
Segmented sliding or folding gate according to one of the preceding claims, characterised in that the running level of the centring or locking curve (18) is variably adjustable.
