Abstract
Abstract A solar ventilator (1) is fittable to an edge (2) having first and second sides corresponding to first and second regions. The edge can be of a barrier, e.g. of a movable window of a motor vehicle or of a building. The ventilator has a suspension (5) for suspending the ventilator from the edge so that the ventilator will be adjacent the first region. The ventilator has a housing (4) having inlet and outlet portions (11,12) for enabling air to be transferred therebetween from a region to the other region. A fan (13) is comprised by the housing so as to enable the transfer of air. A solar generator (15) drives the fan. The ventilator may be arranged for direct or indirect reception of solar radiation.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
139 words
A solar ventilator for fitting to an edge of a member having first and second sides corresponding to first and second regions, the ventilator comprising: suspension means for suspending said ventilator from said edge so that said ventilator later will be adjacent to said first region; housing means having at least one inlet and at least one outlet, said one inlet being adapted to receive air from one of said regions, said one outlet being adapted to discharge to the other of said regions said received air; fan means comprised by said housing means so as to enable said reception and discharge of air; and solar generator means for driving said fan means in response to solar radiation; said suspension means comprising at least one extension means respectably adjustably projectable from at least one side of said suspension means.
Claim 2
Dependent Claim
