Abstract (en)
[origin: EP0045833A2] The invention relates to a rectangular connector for incoming and outgoing air, particularly for domestic flat ducts. The problem underlying the invention is that of providing effective protection against wind and rain for outside use, while however inside connection should also be possible and the flow path should not be impaired. For this purpose the connector has the following features: a) a rectilinear extension piece connected to a top freestanding edge of the upper side of the connector; b) a forwardly extending drip edge of preferably semicircular cross- section at the appertaining bottom freestanding edge of the underside of the connector; c) in each case a lateral connection piece which extends from the drip edge at an angle of about 10 to 30 degrees to the cross-sectional surface of the connector, to the front edge of the extension piece. The invention can be seen most clearly from Figure 2. <IMAGE>
