  • Patent number: 7322395
    Abstract: Disclosed is a tambour door comprising a door leaf that can be rolled up. The door comprises a vertical roller frame for receiving the door leaf, a sliding bar, to which the rollable door leaf is fixed, and an upper horizontal guide rail, in which the sliding bar is displaceably mounted. The invention facilitates a particularly simple, space-saving, modular construction. The rear face or external face of the roller frame is fixed to a wall and the guide rail is configured as a floating guide rail, which is fixed on one side at least indirectly to the roller frame and on the other side in a fixing element that is fastened at least indirectly to a wall. The door can be used as a lavatory door, or in situations requiring privacy protection for a door opening that economizes on space as much as possible.
