Abstract
Cleaning apparatus for the glazing in an atrium-type roof structure (10) comprises an elongate brush (14) rotating about its axis and mounted at opposite ends in carriages (18, 20) running on guide rails (16, 16A) which can move non-synchronously so as to change the angular orientation of the brush, which is formed with two telescopic parts (22, 24) to enable it to change its length as its angular orientation changes (FIGS. 1 and 3). Also described is apparatus for cleaning a barrel arch-type glazed roof structure.
Claims15
Apparatus for cleaning the glazing of a non-planar glazed roofing structure, the apparatus comprising an elongate brush;
- means for driving the brush along a path of movement so as to sweep the brush across the glazing;
- two end mountings on each of which the brush is mounted at a respective end region thereof for rotation about its longitudinal axis, the end mountings being independently movable between one end of said path of movement of the brush and the other end of said path;
- first driving means for rotating the brush about its elongate axis independently of said movement of the end mountings, wherein the brush includes length varying means for enabling the brush to change its effective length between the end mountings when said end mountings move relative to each other, during the movement of the brush along said path.
Apparatus for cleaning the glazing of a non-planar glazed roofing structure, the apparatus comprising an elongate brush;
- driving means for rotating the brush about its longitudinal axis and for driving the brush along a path of movement so as to sweep the brush across the glazing;
- two end mountings on each of which the brush is mounted at a respective end region thereof for rotation about its longitudinal axis, each said end mounting being moveable between one end of the path of movement of the brush and the other end of said path;
- said driving means comprising first driving means for rotating the brush about its longitudinal axis independently of said movement of the end mountings and second driving means for moving at least one end mounting along at least part of its path of movement independently of the other end mounting.
