Abstract
A vent coupler has first and second leg portions and a latch element extending between the leg portions. The coupler may be formed from a single piece of wire and be detachably coupled to a vent damper. The latch element is inserted into a respective air flow slot of a vent cover to engage the vent cover and couple the vent cover to the damper. The coupler may be constructed to permit flexing of the coupler during the insertion process, with the coupler being biased to engage the vent cover when no longer flexed. The vent coupler may snap onto and grip upper and lower edges of an end wall of the damper housing to mount the coupler to the damper. A filter housing may be detachably coupled to the damper housing to support a filter on the opposite side of the damper housing from the vent cover.
Claims23
A vent assembly for a duct opening comprising:
- a damper having a housing with first and second end walls, each end wall having an upper and lower edge portion;
- a vent cover having a plurality of air passageway slots through which air passes through the vent cover, a first of such slots being positioned adjacent to the first end of the damper housing and a second of such slots being positioned adjacent to the second end of the damper housing when the vent cover is in a first position overlying the damper;
- a first vent cover coupler having a first end wall edge engager which engages the upper and lower edge portions of the first end wall and a first latch portion extending from the damper housing into the first slot when the vent cover is in the first position, with the first vent cover thereby being associated with the first slot, a second vent cover coupler having a second end wall edge engager which engages the upper and lower edge portions of the second end wall and a second latch portion extending from the damper housing into the second slot when the vent cover is in the first position, with the second vent cover coupler thereby being associated with the second slot, the first and second vent cover couplers thereby coupling the damper housing to the vent cover when the vent cover is in the first position, at least one of the first and second vent cover couplers comprising a resilient element which is flexed in a first direction to permit insertion of the first and second vent cover couplers into the associated first and second slots, the resilient element moving in a second direction opposite to the first direction and into engagement with the associated slot when no longer flexed.
A coupler for interconnecting a vent cover having vent slots to a damper housing having at least one wall with upper and lower edge portions, the coupler comprising:
- a body having first and second spaced apart upright elongated legs and a first latch portion extending between the first and second legs, each of the first and second legs including an upwardly opening lower hook positioned to receive the lower edge portion of the at least one wall on the hook and an upper recess defining portion which defines a downwardly opening recess spaced from the hook, the downwardly opening recess being positioned to receive the upper edge portion of the at least one wall, each of the first and second legs also including a leg section extending from the hook to the recess defining portion;
- and
- the latch portion being sized for insertion into one of the vent slots to engage the vent cover.
A vent assembly for a duct opening comprising:
- a damper having a housing with first and second end walls, each end wall having an upper and lower edge portion;
- a vent cover having a plurality of air passageway slots through which air passes through the vent cover, a first of such slots being positioned adjacent to the first end of the damper housing and a second of such slots being positioned adjacent to the second end of the damper housing when the vent cover is in a first position overlying the damper;
- a first vent cover coupler having a first end wall edge engager which engages the upper and lower edge portions of the first end wall and a first latch portion extending from the damper housing into the first slot when the vent cover is in the first position, with the first vent cover thereby being associated with the first slot, a second vent cover coupler having a second end wall edge engager which engages the upper and lower edge portions of the second end wall and a second latch portion extending from the damper housing into the second slot when the vent cover is in the first position, with the second vent cover coupler thereby being associated with the second slot, the first and second vent cover couplers thereby coupling the damper housing to the vent cover when the vent cover is in the first position, at least one of the first and second vent cover couplers comprising a resilient element which is flexed in a first direction to permit insertion of the first and second vent cover couplers into the associated first and second slots, the resilient element moving in a second direction opposite to the first direction and into engagement with the associated slot when no longer flexed;
- each of the first and second vent couplers being formed from a single continuous piece of wire;
- the first end wall edge engager being sized to snap fit onto the first end wall and the second end wall edge engager being sized to snap fit onto the second end wall;
- the first coupler including first and second spaced apart upright elongated legs and the first latch portion extending between the first and second legs of the first coupler, each of the first and second legs of the first coupler including an upwardly opening lower hook positioned to receive the lower edge portion of the first end wall on the hook and an upper recess defining portion which defines a downwardly opening recess spaced from the hook, the downwardly opening recess being positioned to receive the upper edge portion of the first end wall, each of the first and second legs of the first coupler also including a central leg section extending from the hook to the recess defining portion;
- the second coupler including first and second spaced apart upright elongated legs and the second latch portion extending between the first and second legs of the second coupler, each of the first and second legs of the second coupler including an upwardly opening lower hook positioned to receive the lower edge portion of the second end wall on the hook and an upper recess defining portion which defines a downwardly opening recess spaced from the hook, the downwardly opening recess being positioned to receive the upper edge portion of the second end wall, each of the first and second legs of the second coupler also including a central leg section extending from the hook to the recess defining portion;
- wherein the damper housing has an exterior and an interior and wherein the central leg sections of the first and second couplers are each positioned at the exterior of the damper housing, each central leg section having an upper end portion which extends away from the exterior surface of the end wail to which the respective coupler containing the central leg section is mounted, and wherein each leg includes a latch supporting portion having a first section which extends inwardly from the recess defining portion of the leg to a location inwardly of the end wall to which the coupler including the leg is mounted and a second section extending upwardly and outwardly from the first location, the latch portion comprising a cross—piece extending between the second sections of the first and second legs of the coupler which includes the latch portion.
5 more elements
A vent assembly for a duct opening comprising:
- a vent cover with at least first and second spaced-apart air flow slots;
- a damper housing;
- and
- a damper clip means formed of wire for detachably coupling the damper housing to the vent cover.
1 more element
A clip for detachably coupling a damper housing to a slot of a vent cover the damper housing having at least one end wall, the clip comprising:
