Benefits of technology
[0009]Thus, the dust-collecting assembly of the present invention avoids the time and inconvenience of connecting a shop-vac to the power tool. It avoids the space requirements of a typical shop-vac. Less electric power is required. Power-tool portability is not affected. Emptying the smaller bag assembly is less work.
Problems solved by technology
Although such a dust-bag arrangement proves useful in some respects, it relies only on the tool-produced airflow.
First, a typical shop-vac is somewhat large and bulky, and connecting it to the dust port involves some time and inconvenience.
Furthermore, the electric power required by a shop-vac can be significant for such a use, and the use of multiple shop-vacs only compounds that concern.
Moreover, use of a shop-vac affects tool portability because the shop-vac must be transported with the power tool.

Embodiment Construction
[0026]FIG. 1 of the drawings shows a power tool dust-collecting assembly constructed according to the invention in the form of a motorized dust bag assembly 10. Generally, the assembly 10 includes an airflow-producing subassembly 11, a bag subassembly 12, and a coupling component 13. Those parts are connected together to form a combination of components (i.e., the motorized dust bag assembly 10) such that the assembly 10 is adapted to be connected to a dust port 14 on a power tool 15 and to be physically supported by the dust port 14 without resting upon a support surface 16 of a table, bench, or other supportive structure.
[0027]As such, the assembly 10 can be connected to and supported by the dust port 14 in place of a commonly used dust bag accessory (not shown) of the type existing in the prior art. So connected and supported, the assembly 10 more effectively captures sawdust and / or other dust produced by the power tool 12 without otherwise affecting operation or portability of t...

Abstract
A power tool dust-collecting assembly for collecting dust from a dust port of a power tool includes an airflow-producing subassembly for sucking sawdust and / or other dust from the dust port. A coupling component is provided for coupling an air-and-dust input port of the airflow-producing subassembly to the dust port of the power tool, and a bag subassembly is included for collecting dust from a dust output port of the airflow-producing subassembly. Those parts form a motorized dust bag that is adapted to be physically supported by the dust port of the power tool without requiring other support. One embodiment includes a secondary input portion of the coupling component for capturing dust from beneath the power tool. Various adapters and accessories enable use for various tasks while disconnected from the power tool.
Description
CROSS REFERENCE TO RELATED APPLICATION[0001]This application is a continuation in part of copending U.S. patent application Ser. No. 11 / 998,490 by the same inventor that was filed Nov. 30, 2007 and later abandoned in favor of and subsequent to the filing date of this application.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]This invention relates generally to the fields of woodworking and power tools, including power saws, power sanders, and the like. It relates more particularly to a dust-collecting assembly for collecting sawdust and / or other dust produced and / or expelled by such a tool, and to accessories for adapting the dust-collecting assembly to other tasks.[0004]2. Description of Related Art[0005]Health, hygiene, and work-site cleanup issues make the production of sawdust and / or other dust by a power tool a major concern. Many dust-collecting techniques and devices have been invented as a result. Some current dust-collecting designs for chop saws, miter saws, and ...
