Abstract

A wall-integrable lens arrangement and a wall-integrated device with a connection housing and such a lens arrangement includes a connection housing having a radiation-emitting element. The connection housing is arranged on a first side of a wall and has an attachment portion and a connecting member. A lens arrangement has a lens head that is transparent to the radiation and an attachment portion and a connection member. The wall has a wall breakthrough through which at least one of the attachment portions projects, the connection members of the connection housing and the lens arrangement being mutually engaged. The wall breakthrough and at least one of the attachment portions that projects through it are complementary and formed in such a manner that the lens arrangement is maintained in a pre-specified horizontal position or rotational position and secured in the position against rotation.

Dependent claims

A lens installation comprising a wall-integrable lens arrangement intended to be fastened to a wall and to which a connection housing can be mounted, the lens arrangement having a lens head that is transparent to radiation, an attachment portion and a connecting member, the attachment portion projecting into a wall breakthrough having at least two discrete opposed conical surface portions and the connecting member serving to be connected by a connecting member of the connection housing;

characterized in that the attachment portion of the lens arrangement is formed complementary to the breakthrough and has at least two discrete attachment contact surfaces in the form of conical surfaces positioned opposite each other in respect to a longitudinal axis of the attachment portion and complementary to the conical surface portions of the wall breakthrough such that it is inserted and is maintained in a pre-specified fixed horizontal rotational position defined by the position of the attachment conical surfaces of the wall breakthrough and is secure against rotation in the wall breakthrough.

A lens installation, comprising a wall-integrated lens system comprising a connection housing, a lens arrangement and a wall, the connection housing having at least one of a radiation-emitting or a radiation-absorbing element, being arranged on a first side of the wall, and having an attachment portion and a connecting member;

the lens arrangement having a lens head that is transparent to the radiation of the radiation-emitting and radiation-absorbing element in a direction outwardly from a second side of the wall and having an attachment portion and a connecting member;
the wall having a non central-symmetric wall breakthrough through which at least one of the connection housing and lens arrangement attachment portions at least partially project, the housing and lens arrangement connecting members being in mutual engagement;
characterized in that the wall breakthrough and at least one of the at least one attachment portions projecting through the wall breakthrough are each complementarily formed with at least two discrete opposed attachment contact surfaces in the form of conical surfaces portions, and are inter-engaged whereby the attachment conical surfaces are positioned opposite each other in respect to a longitudinal axis of the attachment portion such that the lens head is maintained in a pre-specified fixed horizontal or rotational position defined by the position of the attachment conical surfaces of the wall breakthrough and secured in the position against rotation.
