The aim of the invention is to provide a rubber profiled safety strip or an elastic profiled safety strip which can carry out a signaling function. To this end a profiled safety strip (10) is provided for a door (15) of a transport means, wherein the profiled safety strip (10) contains an opaque elastic main part (11) in which at least one receiving region (17, 18) is formed, and in the at least one receiving region (17, 18) an insert strip (12, 31) is disposed, which contains at least one light source (13, 32) and is made of an elastic material that is at least partly transparent.

The modular, retractable barrier is a room partition. The modular, retractable barrier comprises one or more barrier structures. Each of the one or more barrier structures comprises a plurality of scroll rods and a mesh barrier. The mesh barrier is a scroll like structure. When each of the plurality of scroll rods is separated the mesh barrier is deployed in the space between each of the plurality of scroll rods to form a barricade structure. When the plurality of scroll rods is later brought together, the mesh barrier is retracted. The modular, retractable barrier is a modular structure wherein any first barrier structure selected from the one or more barrier structures can be removably attached to any second barrier structure selected from the one or more barrier structures such that overall span of the barricade formed by the modular, retractable barrier can be increased.

The present invention is directed to a roll-up wall. The roll-up wall and its components may be used to divide existing larger spaces into smaller spaces with a sound-attenuating barrier. In this invention a sound-attenuating panel is attached to a roller drum which, when turned on its axis by a winding mechanism, deploys or retracts the sound-attenuating panel. This invention discloses details of the sound-attenuating panel, the roller drum, a sound-attenuating guide system, a lower sound-attenuating seal, and an interlocking system. More particularly, this invention discloses an interlocking system which removably attaches a sound-attenuating panel to a roller drum. This invention discloses a plurality of embodiments of the interlocking system and provides detailed descriptions of each embodiment.
