ABSTRACT:
TECHNICAL FIELD
The present invention relates to a louver assembly and wherein the louvers are each provided with a connector which is engaged by an end recess of a connecting arm of a control rod, having at least two spaced-apart arms, whereby to articulate the louvers about their pivot connections to orient and maintain them at a desired angle.
BACKGROUND ART
Shutter structures are known and comprised of louver assemblies having control rods which permit the louvers to pivot in synchronism to a desired position from a closed position to an open position. Examples of such louver adjustment mechanisms are disclosed in U.S. Pat. Nos. 5,187,896, 2,309,354 and 2,037,176. A disadvantage of such louver adjusting mechanisms is that although some of these may provide adjustment to position a plurality of louvers at a desired angle, their mechanisms do not provide for the louvers to remain at that angle when subjected to wind pressure. Accordingly, depending on the wind orientation, it is conceivable that in a room some shutters which are positioned over a window opening facing the wind may be oriented at different angles or shut as compared with shutters of other window openings oriented differently with respect to the wind. This will affect the ventilation of a room or the amount of light which is desired to penetrate the particular room. These adjusting mechanisms are also difficult to assemble due to their many component parts and are difficult to repair. There is therefore a need to provide a louver assembly with an adjustment mechanism which can secure and maintain louvers at a desired angular orientation and which is simple to install and repair.
SUMMARY OF INVENTION
It is a feature of the present invention to provide a louver assembly with a multi-position adjustment mechanism which substantially overcomes the above-mentioned disadvantage of the prior art and which fulfills the desired need.
Another feature of the present invention is to provide a louver assembly and wherein connectors are detachably secured in an edge of louvers and wherein a control rod is provided with connecting arms having an end recess which can clampingly engage the connectors and maintain the louvers angulated at a desired angle in a shutter frame.
Another feature of the present invention is to provide a shutter frame incorporating therein the louver assembly and adjustment mechanism of the present invention.
According to the above features, from a broad aspect, the present invention provides a louver assembly comprising two or more louvers of substantially rectangular outline and having pivot means at opposed ends thereof adapted for hingedly securing the louvers between opposed styles of a shutter frame for pivoting motion of the louvers in the frame on a longitudinal axis of the louvers. Each of the louvers has a connector secured to an inner longitudinal side edge thereof. The connector has a cavity with a connector rod extending thereacross and extending co-extensively to the longitudinal axis. The connector rod has engageable means on an outer surface thereof. A control rod is provided with two or more transverse connecting arms each having a connecting end recess. The connecting end recess has connecting means formed in a curved clamping inner face thereof for receiving the engageable means of the connector rod captive therein by clamping pressure of the connecting end recess about the connector rod whereby to angulate the louvers at a desired angle with respect to their longitudinal axis.
