Benefits of technology
The present invention is a dust containment apparatus that can be easily attached to a wall, ceiling, or surface to collect dust or particles during work. It consists of a bag with two openings, one large enough to encompass the work area and one for the worker's hand and tools. The bag can be securely attached to the surface with the first opening around the work area. The second opening is designed to fit snugly around the worker's hand, wrist, or arm where it enters the bag. This invention helps to prevent dust or particles from spreading during work, making it easier to keep the workplace clean.
Problems solved by technology
Drilling holes, sanding or performing other types of work on interior walls, ceilings or other surfaces can generate a great deal of dust and other particulates.
Drywall is commonly used to make interior walls and ceilings, and the dust and other particulate that are generated from sanding or cutting through drywall can be extremely fine and difficult to contain.
Drywall dust is extremely lightweight, and can easily becoming airborne and travel throughout room or the job site.
Drywall dust is also a known health hazard and a huge nuisance in remodeling and new construction.
It can easily be drawn into a home's ventilation system, spreading through the home and causing problems with the ventilation system.
The problem is particularly serious when repairs or work are being done on a wall or surface within an existing room that already contains furniture, equipment or other items, because the dust will settle onto and into the items.
Drywall dust harms computer and audio equipment.
Drywall dust can also contaminate every finish in a home or other building, including wall and trim paint, wood finishes, hardwood floors and other surfaces.
However, the devices tend to be bulky, heavy and costly.
However, while such systems can prevent generated dust from escaping beyond the defined space, the dust will still settle inside that space and onto any items that are inside the space.
The dust must eventually be swept or vacuumed up, which can take a great deal of time and effort.
Further, although this approach can be well suited for large-scale construction projects, it is not well suited for situations in which small, isolated repairs or installations are to be performed on a relatively small section of a pre-existing wall within a room.

Embodiment Construction
[0015]Turning first to FIG. 1, a dust containment apparatus 10 comprises a bag 12 having a first end 14 and second end 16. At the first end 14, the bag 12 has a first opening 18 formed therein. At the second end 16, the bag 12 has a second opening 20 formed therein.
[0016]As shown in FIG. 2, the device is adapted to have the first end 14 of the bag 12 affixed to a wall, ceiling or other surface (element 22 in FIG. 2), with the perimeter of the first opening 18 surrounding the area of the surface where the work is to be performed. A person's hand (element 24 in FIG. 2) can be inserted into the bag 12 through the second opening 20 while gripping a hand tool (element 26 in FIG. 2), which can be powered or non-powered.
[0017]The first opening 18 has a perimeter that is large enough to encompass the area of the surface where work is to be performed. The second opening 20 is also preferably circular with a perimeter that is large enough to permit a person to insert his or her hand and a han...

A portable, removable dust containment system is disclosed for capturing and containing the dust generated by work performed on a work surface, such as the wall or ceiling inside a room. The device includes a transparent plastic bag with a first large opening at one end, and with the bag tapering to a smaller second opening at a second end. The device is removably affixed by an adhesive onto a wall surface, with the perimeter of the first opening surrounding an area where work is to be done on the wall. The user extends his or her hand through the second opening and closes the second opening. Any dust generated by the work is captured and contained within the bag and can be discarded when the bag is removed from the wall.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This patent application claims priority to U.S. Provisional Application No. 61 / 454,478, filed Mar. 18, 2011.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention pertains generally to the field of portable dust containment systems for use in construction or renovation projects. More particularly, the invention pertains to a relatively small, portable dust containment apparatus that can be removably affixed onto a wall, ceiling or other surface, covering a relatively small area where the surface is to be sanded, cut or otherwise worked upon, to capture and contain dust that is generated by the work.[0004]2. Description of the Related Art[0005]Drilling holes, sanding or performing other types of work on interior walls, ceilings or other surfaces can generate a great deal of dust and other particulates. This is particularly true when the walls or ceilings are constructed using drywall (also known as plasterboa...
