ROLLER SHUTTER FOR OPENING AND CLOSING A DOORWAY
The invention relates to a roller shutter for opening and closing a doorway (12) having a door blade (11), the door blade (11) comprises several rigid shutter elements (13) which are hinged with each other, the shutter elements (13) are guided by side rails (18) at opposed sides of the doorway (12), wherein each shutter element (13) provides an end piece (19) at each horizontally spaced end of the shutter element (13) for spacing layers of rolled up shutter elements (13) apart from each other, each end piece (19) has at least one concave section (27) for coiling the end pieces (19) on a coiling device (14) and/or in layers on top of each other. For reducing the risk of weakening a connection between the end piece (19) and the shutter element (13), for reducing noise and/or vibrations during the opening and/or closing of the door way and/or to increase the stability of the roller shutter the roller shutter (10) is characterized in that at least some of the end pieces (19) having at least one plane gliding section (28), the plane gliding section (28) is arranged for interacting with a slide guide (36) of the side rail (18) for leading the end pieces (19) into and/or out of the side rails (18).
