Abstract
A debris collection device with a self cleaning retention system that is designed for powered tools such as a sander. One embodiment of the system has an inflatable collection bag and a bag retention system, which further includes an integral bag adapter nozzle for retaining the collection bag to the debris exhaust of a tool such as a sander. For one embodiment of the debris collection device, the retention system can also has a tube, pipe or bracket which connects the adapter to powered tool such as a sander.
Claims10
A debris collection device with a self sealing retention system comprising:
- a.) a bag having a reclosable zippered opening constructed such that when the zippered opening is zipped closed the bag defines a substantially closed interior volume whereby only a small debris entry opening remains;
- b.) a substantially tubular resilient elastomeric adapter having an interior hollow substantially cylindrical channel extending therethrough end to end and where an exterior surface of said adapter has forward and aft protrusions formed therein and proximately spaced apart from each other forward to aft along a length of said adapter defining a valley between said forward and aft protrusions;
- and
- c.) where the adapter is inserted lengthwise through the debris entry opening and the inner edges of the debris entry opening are fixedly attached to the adapter in the valley of the adapter such that the interior channel of the adapter communicably links the interior volume of the bag with an exterior area surrounding the bag.

A debris collection device with a self-sealing retention system comprising:
- a.) a bag having a reclosable zippered opening constructed such that when the zippered opening is zipped closed the bag defines a substantially closed interior volume whereby only a small debris entry opening remains;
- b.) a sleeve open on opposing ends and a mouth of one end secured to and about the inner edges of the debris entry opening;
- c.) a substantially tubular resilient elastomeric adapter having an interior hollow substantially cylindrical channel extending therethrough end to end where an interior wail of the channel has a protruding bead ring and where an exterior surface of said adapter has forward and aft protrusions formed therein and proximately spaced apart from each other forward to aft along a length of said adapter defining a valley between said forward and aft protrusions;
- and
- d.) where the adapter is inserted lengthwise through the debris entry opening and further through the interior of the sleeve and the sleeve is fixedly attached to the adapter in the valley of the adapter such that the interior channel of the adapter communicably links the interior volume of the bag with an exterior area surrounding the bag.

- d.) where the adapter is inserted lengthwise through the debris entry opening and further through the interior of the sleeve and the sleeve is fixedly attached to the adapter in the valley of the adapter such that the interior channel of the adapter communicably links the interior volume with an exterior area surrounding the bag;
- and
- e.) an elongated extension tube having a recessed ring area formed in an exterior surface on an exit end of the extension tube where the exit end of the extension tube is press fit lengthwise through the interior channel of the adapter a distance sufficient to mate the recessed ring area and the protruding bead ring.
