  • Device and method for lifting a pool skimmer basket
    Patent number: 8042849
    Abstract: The present invention is directed to a skimmer basket lifting tool that enables a user to engage and remove a skimmer basket for cleaning without having to contact the debris accumulated within the basket. The skimmer basket lifting tool comprises a lifting handle which has both a proximal and a distal end, a base portion, including an attachment point for engaging the distal end of the lifting handle, and a pair of opposed skimmer basket crossbar engagement elements extending downward from the base portion. The opposed crossbar engagement elements are oriented such that rotation of the base portion, following insertion of the base portion into a skimmer basket housing, results in reversible engagement of the opposed crossbar engagement elements with the skimmer basket crossbar. This reliable, reversible engagement enables the skimmer basket to be lifted from the skimmer basket housing.
