Abstract

The invention relates to a rolling gate (100), in particular a high-speed rolling gate, comprising a leaf (110) in the form of a flexible curtain, side guides receiving the side edges of the leaf (110) therein and generating drive Drive (140) of the driving force of the door leaf (110), wherein the door leaf (110) has an elastically designed terminal element (112) on the forward edge, which is tensioned by a lateral force component applied laterally between the side guides. In particular, the rolling shutter (100) is characterized in that said driving force of the driver (140) acts on the terminating element (112) of the door leaf (110), thereby providing said laterally applied transverse force component to tension the door leaf ( 110) and a tension component generally directed in the direction of movement of the door leaf (110) to close said door leaf (110). Thus, an improved rolling shutter ( 100 ) is achieved which has a high operating reliability and presents less danger to persons or objects in the event of a collision.

Description

technical field

[0001] The invention relates to a rolling gate, in particular a high-speed rolling gate, comprising a door leaf in the form of a flexible curtain, side guides in which the side edges of the door leaf are received, and a drive generating a driving force for driving the door leaf, wherein the door leaf has Elastically designed terminating element on the forward edge tensioned between the side guides by a laterally applied lateral force component. Background technique

[0002] Roller shutters with a flexible curtain formed of PVC or the like have been used in practice for a long time. It has proven to be of excellent value for creating a draft-tight closure, for example between rooms in a larger hall or the like. Such a roller shutter has the advantage of lower weight compared to a shutter arrangement with a door leaf formed from slats or segments. Therefore, it can be operated at very high speeds.

[0003] Usually, such roller shutters have a roller shaft, a...
