Abstract
A device for retrieving small items which have fallen into common residential drains and have become lodged between the drain inlet and the distal end of the drain trap. The device consists of a elongate tubular portion having an inflatable pouch or balloon fixed to one end and a resilient squeezable bulb at the opposing end. Manually depressing the bulb after insertion of the pouch beyond the trap causes the pouch to inflate and engage the side walls of piping of the drain. Lifting the inflated pouch upward to the drain inlet carries any loose items in front of the pouch to the drain inlet for retrieval.
Claims3
A device for retrieving small items lost in a common household drain of the type having a drain opening communicated to a U-shaped trap portion of the drain via conventional piping having interior walls, comprising in combination, an elongate, hollow, flexible tubing portion having an outer diameter significantly smaller than the piping of said drain and a length greater than the distance between said drain opening and a distal end of the U-shaped trap portion;
- an inflatable resilient pouch normally disposed in a deflated condition having a port opening mounted in sealed communication to one end of said flexible tubing portion to form a flexible tip;
- and means for inflating and deflating said pouch connectable to the opposing end of said tubing portion for selectively inflating said pouch to a diameter at least equal to the inner diameter of the piping of said drain for drawing said pouch in slideably and sealed engagement with said interior walls of said piping in a direction toward said drain opening while maintaining said pouch in an inflated condition;
- said means for inflating and deflating said pouch forming a closed pressure system with said pouch and said tubing.
A method for retrieving relatively small items loosely lodged in a U-shaped trap portion of a conventional household drain including conventional piping having interior walls and a drain inlet, comprising the steps of:
- inserting a flexible, hollow tubing portion having an inflatable tip portion normally in a deflated condition into said drain inlet until said tip portion is disposed at or near a distal end of said U-shaped trap portion of said drain with the opposing end of said tubing portion maintained outwardly of said inlet, said tubing portion and said tip portion in its normally deflated condition having an outer diameter significantly less than the inner diameter of the piping of said drain;
- causing air pressure to be introduced into the opposing end of said tubing portion to inflate said inflatable tip portion into force-transmitting engagement with said piping;
- drawing said tubing portion and said inflated tip portion outwardly toward said drain inlet in slideable engagement with said interior walls of said piping until said inflated tip portion is closely adjacent to said drain inlet and maintaining said tip portion in an inflated condition;
- manually retrieving any loose items carried outwardly to said drain inlet in front of said inflated tip portion and then causing air to be released from the opposing end of said tubing portion to deflate said tip portion sufficiently to permit complete removal thereof through said drain opening.
