Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
A device for boosting air flow from heating and air conditioning registers comprised of: an exterior cover containing side margins having a foam rubber backing or gasket with means of installation so as to form a seal between the device and the surface to which the device is attached; elevated or protruding portions in the exterior cover containing two panels or cavities, one of said panels which may have an on-off/variable control switch or other assessories, such as a smoke alarm or air freshener; a central grill section between the two panels containing louvres for directing and diffusing air flow through a central circular portion in the grill section; a housing attached to the interior of said grill section; a fan in said housing which is driven by an induction motor at the center of the blades; a switching mechanism which acts in conjunction with the on-off switch for varying the power supply through the fan; and an electrical wire and plug for providing electrical current to the device.
Claim 2
Independent Claim
169 words
A device for boosting air flow from heating and air conditioning registers comprised of: an exterior cover containing side margins having a foam rubber backing or gasket with means of installation so as to form a seal between the device and the surface to which the device is attached; elevated or protruding portions in the exterior cover containing two panels or cavities, one of said panels which may have an on-off/variable control switch or other assessories, such as a smoke alarm or air freshener; a central grill section between the two panels containing louvres for directing and diffusing air flow through a central circular portion in the grill section; a housing attached to the interior of said grill section; a fan in said housing which is driven by an induction motor at the center of the blades; a switching mechanism which acts in conjunction with the on-off switch for varying the power supply through the fan; and an electrical wire and plug for providing electrical current to the device.
Claim 3
Dependent Claim
17 words
