ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method for containing debris during a cut out procedure within a ceiling of a building.
2. Background of the Prior Art
Installing grills or registers into an existing ceiling is typically a two man procedure. One man is positioned within the attic to perform the actual cut out procedure while another man is positioned underneath the area to be cut in order to capture the debris that is created during the cut off procedure. This second man holds a receptacle about the area to be cut out in order to capture the debris. Without this second man, substantial debris falls underneath the cut out area, such debris being unwelcome by the owner of the building upon which the procedure is being performed. Therefore, the second man used for capturing the debris before it enters the area underneath the cut out procedure area is an essential component of the job. Although this two man system achieves its intended purpose, it is manpower intensive and its relatively economically inefficient.
Therefore, there is a need in the art for a system that allows a single worker to perform a cut out procedure within an existing ceiling without the need for an additional worker and without creating a mess underneath the work area. Such a system must allow the worker to effectively perform the cut out procedure and must capture the resulting debris without creating a mess underneath the cut out area. Such a system must be relatively simple and straightforward to implement and must rely on relatively simple tools to achieve its intended purpose.
SUMMARY OF THE INVENTION
The method for capturing debris of the present invention addresses the aforementioned needs in the art. The method allows a single worker to perform a cut out procedure and capture the debris thereby created without making a mess underneath the cut out area. The method incorporates a tool which is of relatively simple design and which is easy to operate. The method is simple in design and implementation.
The method for containing debris around a cut out area of the present invention comprises the steps of providing a telescoping pole having a first end and a second end. Providing a base and attaching, either fixedly or removably, the first end of the telescoping pole to the base. Providing a receptacle having a closed bottom with an inset cup, and an open top having an outer periphery and attaching the second end of the telescoping pole, either fixedly or removably, threadably or otherwise, to the cup of the receptacle, and positioning the receptacle such that the outer periphery encompasses the cut out area. The receptacle has a shape that conforms to the shape of the cut out area (generally rectangular for an air conditioning grill, generally round for a light, etc). The receptacle is made from a resilient material such as plastic so that it conforms to the cut out area and provides a relatively air tight fit around the cut out area in order to prevent debris from escaping therefrom. The receptacle also applies pressure to the cut out area, reducing vibration during the cut out procedure and allowing a tighter cut. A compression fitting or any other appropriate locking mechanism can be used to lock two sections of the telescoping pole in place once the receptacle is positioned snugly against the ceiling.
