1. Lift-type door having a slatted shutter in guide tracks. 2.1. The prior art rolling shutter doors employed as covers for a door opening, in which the door leaf is laterally guided and vertically raised, exhibit only inadequate high-speed operating properties owing to their design, and cause excessively high noise emission when in operation. 2.2. The lift-type door according to the invention comprises two guide tracks (2, 2'), which are arranged at the two opposing sides (3, 3') of the door opening (1), and a slatted shutter (12) with slats (14) mounted with an intermediate clearance in each case on hinge straps (20 20') such that the joint pins (24, 24') engage within a space (34) between the adjacent slats (14). 2.3. Application of the lift-type door as a high-speed door. 3. Fig. 1.
