Abstract
Abstract A ventilator for panel mounting, for example in a glass window pane or an automobile car body panel, consists of a hollow main body having a stem carrying an electrically driven fan and fixed through a hole in the panel, and two branches off the stem to each of which branches is connected as a prolongation thereof an elongate flexible duct having a plurality of vent openings. The duct preferably has a shutter behind the vent openings and internal air guides in the form of resilient sheet material housed in grooves formed in two opposite sidewalls of the duct for directing a proportion of the airflow to each opening. The ducts may be rotatable about their longitudinal axes and can be sprung off for cleaning. The main body may house a replaceable air filter element.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
184 words
A ventilator adapted for panel mounting comprising a hollow body member having a stem and at least one side branch leading off the stem, means associated with said stem adapted to secure said stem within a hole cut in a panel for mounting the ventilator to the panel, an elongate duct member communicating with said at least one branch of said body member and mounted with respect to said body member so as to form a general prolongation of said branch, a plurality of vent openings in said duct member, shutter means slidably mounted within said duct member behind said vent openings and manually operable to vary the area of said vent openings, internal air guide means within said duct member, which air guide means comprise strips of resilient sheet material housed in grooves formed in two opposite inside walls of said duct member, and which sheet material strips divide the interior of said duct member into a plurality of separate air-flow passageways corresponding in number to the number of said vent openings, and each of said vent openings communicating with an individual passageway.
Claim 2
Dependent Claim
184 words
A ventilator adapted for panel mounting comprising a hollow body member having a stem and at least one side branch leading off the stem, means associated with said stem adapted to secure said stem within a hole cut in a panel for mounting the ventilator to the panel, an elongate duct member communicating with said at least one branch of said body member and mounted with respect to said body member so as to form a general prolongation of said branch, a plurality of vent openings in said duct member, shutter means slidably mounted within said duct member behind said vent openings and manually operable to vary the area of said vent openings, internal air guide means within said duct member, which air guide means comprise strips of resilient sheet material housed in grooves formed in two opposite inside walls of said duct member, and which sheet material strips divide the interior of said duct member into a plurality of separate air-flow passageways corresponding in number to the number of said vent openings, and each of said vent openings communicating with an individual passageway.
Claim 3
Dependent Claim
82 words
A ventilator as claimed in claim 1, comprising means mounting said duct member for rotation about its longitudinal axis with respect to said body member, including means rotatably mounting one end of said duct member on said body member and spring clip means releasably and rotatably retaining the other end of said duct member whereby on flexing of said spring clip means to release the said other end of said duct member said duct member can be detached from said body member.
