Embodiment Construction

[0023]The collective views in FIGS. 2 through 4 show the invention apparatus, generally denominated 10, comprises a debris trap and filter to cover floor vent openings to be used during construction of residential or commercial buildings that use a forced air HVAC system. Device 10 prevents common construction debris (e.g. pieces of wood, wire, wallboard scraps, nails, bottles, paper and cups) as well as compound dust, sawdust and sweeping compound from entering the duct boots through the floor vent openings and settling in the duct work.

[0024]FIG. 1 is a sectional view of a typical floor (1) and vent opening (2) with connecting duct boot (3) and the HVAC duct (4).

[0025]FIG. 2 shows the various components of device 10. The device 10 blocks relatively large debris pieces including sawdust, plasterboard shavings, nails, and the like by way of a screen or mesh 5 (made of paper or wire) disposed across an upper portion of the device. Smaller debris and fine particulates are entrapped wi...

Abstract

A temporary debris trap and air filter which may be installed on floor vent openings in the early stages of home or commercial construction. After the floors are cut open for vent openings, the trap and filter is laid over the opening and easily affixed by adhesive strips on the flanges. The screen on top prevents construction debris from entering the duct boots and duct system and the filter below prevents dust and fine particles from entering the system while simultaneously allowing the free flow of cooled or heated air to enter the room area. The air will not be obstructed so the building and construction materials can be acclimatized during the construction period, the HVAC system can be tested and adjusted for proper air balance and the construction workers can breath filtered and conditioned air.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Provisional Application Ser. No. 60 / 877,980 filed Jan. 2, 2007.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.REFERENCE TO A MICROFICHE APPENDIX[0003]Not applicable.BACKGROUND INFORMATION AND DISCUSSION OF RELATED ART[0004]In modern home building construction, HVAC systems typically sheet metal ducts that are routed to communicate with one or more vent openings in the floor of a given room. A preformed sheet-metal “boot” is fitted inside the perimeter of each opening for connection with the duct work. Two common sized of floor vent openings are 4 in. by 10 in. and 4 in. by 12 in. FIG. 1 illustrates a typical floor boot and duct installation.[0005]It is not unusual for workers to allow the floor boot to remain uncovered during construction, and it is customary to operate the HVAC system to control the ambient temperature in the rooms under construction to permit th...
