LENS ARRANGEMENT FOR INTEGRATION INTO A WALL, WALL-INTEGRATED DEVICE WITH A CONNECTION HOUSING AND THE LENS ARRANGEMENT, METHOD OF INSTALLING THE DEVICE, AND TRANSPORTATION INSTALLATION WITH THE DEVICE

摘要

Wall-integrable lens arrangement and wall-integrated device with a connection housing and such a lens arrangement. The connection housing (7, 11) has a radiation-emitting element (10). It is arranged on a (first) side of a wall (3) and has a housing-side attachment (8) with a housing-side connecting member (8.2). A lens arrangement (20) has a lens head (6) that is transparent to the radiation in the direction of the second side of the wall (3) and to which a lens-side attachment (6.1) with a lens-side connection member (6.2) adjoins. The wall (3) has a wall breakthrough (5) through which at least one of the attachments (6.2, 8) projects, the housing-side connection member (8.2) and the lens-side connection member (6.2) being mutually engaged. The wall breakthrough (5) and at least one attachment (6.1, 8) that projects through it are complementary and formed in such manner that the lens arrangement (20) is arranged in a pre-specified horizontal position or rotational position and secured in this position against rotation.
