Abstract

Abstract An air register with a filter element for filtering particulars from the air flowing from the ductwork into a room. The filter element is replaceable as necessary and is sandwiched within a recess in the register face plate by a pivotable retaining plate. The retaining plate lockingly engages the face plate to retain the filter across the openings of the register. The retaining member facilitates replacement of the filter without having to remove or disassemble the body of the register.

An air register for dispensing air into a room, said register comprising: a body portion having a fluid passageway directing air through said register; a fixed face plate having at least one opening for the flow of air through said face plate, said face plate fixedly mounted to said body portion such that said body portion depends from an inner surface of said face plate and said face plate forming a support surface, said at least one opening of said face plate directing substantially all air flow from said fluid passageway through said register; a retaining plate pivotably mounted to an outer surface of said face plate, said retaining plate lockingly engaging said face plate for selective pivotal opening of said retaining plate relative to said fixed face plate; and a filter element positionally captured between said fixed face plate and said pivotable retaining plate to remove airborne particles flowing through said register, said filter element selectively removable from between said face plate and said retaining plate upon pivotably opening said retaining plate relative to said face plate.
Claim 2
Dependent Claim 178 words
An air register for dispensing air into a room, said register comprising: a body portion having a fluid passageway directing air through said register; a fixed face plate having at least one opening for the flow of air through said face plate, said face plate fixedly mounted to said body portion such that said body portion depends from an inner surface of said face plate and said face plate forming a support surface, said at least one opening of said face plate directing substantially all air flow from said fluid passageway through said register; a retaining plate pivotably mounted to an outer surface of said face plate, said retaining plate lockingly engaging said face plate for selective pivotal opening of said retaining plate relative to said fixed face plate; and a filter element positionally captured between said fixed face plate and said pivotable retaining plate to remove airborne particles flowing through said register, said filter element selectively removable from between said face plate and said retaining plate upon pivotably opening said retaining plate relative to said face plate.
Claim 3
Dependent Claim 40 words
The register as defined in claim 1 wherein said face plate includes a recessed seat formed on said outer surface for receiving said filter element, said at least one opening for the flow of air disposed in said recessed seat.
Claim 4
Dependent Claim 23 words
The register as defined in claim 2 wherein said retaining plate includes a plurality of openings for dispensing air flowing through said register.
Claim 5
Dependent Claim 41 words
The register as defined in claim 2 wherein said retaining plate includes at least one pivot finger formed along a first edge of said retaining plate, said at least one pivot finger received in corresponding slots formed in said face plate.
Claim 6
Dependent Claim 47 words
The register as defined in claim 4 and further comprising locking means for lockingly engaging said retaining plate to said face plate, said locking means including locking tabs formed on said retaining plate, said locking tabs selectively lockingly engaging said face plate upon closing said retaining plate.
Claim 7
Dependent Claim 23 words
The register as defined in claim 1 wherein said body portion includes at least one adjustable louver for controlling airflow through said register.
Claim 8
Dependent Claim 31 words
The register as defined in claim 6 wherein said body portion forms a rectangular tube directing airflow through said register, said at least one adjustable louver disposed within said rectangular tube.
Claim 9
Dependent Claim 203 words
An air register for dispensing air into a room, said register comprising: a rectangular body portion having a fluid passageway directing air through said register; a rectangular face plate having an outer support surface, an inner surface and at least one opening for the flow of air through said face plate, said body portion fixedly mounted to said inner surface with said fluid such that said face plate extends across said fluid passageway with said fluid passageway in direct fluid communication to direct air flow through said at least one opening, said face plate including a recessed seat formed in said outer support surface of said face plate; a filter element seated within said recess of said face plate across said at least one opening of said face plate; and a retaining plate pivotably attached to said outer surface of said face plate and selectively closable to positionally capture said filter element between said fixed face plate and said pivotable retaining plate within said recessed seat, said retaining plate including a plurality of fixed vanes whereby air flowing through said register is filtered of airborne particles by said filter element and disposed into the room by said fixed vanes of said retaining plate.
Claim 10
Dependent Claim 203 words
An air register for dispensing air into a room, said register comprising: a rectangular body portion having a fluid passageway directing air through said register; a rectangular face plate having an outer support surface, an inner surface and at least one opening for the flow of air through said face plate, said body portion fixedly mounted to said inner surface with said fluid such that said face plate extends across said fluid passageway with said fluid passageway in direct fluid communication to direct air flow through said at least one opening, said face plate including a recessed seat formed in said outer support surface of said face plate; a filter element seated within said recess of said face plate across said at least one opening of said face plate; and a retaining plate pivotably attached to said outer surface of said face plate and selectively closable to positionally capture said filter element between said fixed face plate and said pivotable retaining plate within said recessed seat, said retaining plate including a plurality of fixed vanes whereby air flowing through said register is filtered of airborne particles by said filter element and disposed into the room by said fixed vanes of said retaining plate.
Claim 11
Dependent Claim 35 words
