Abstract
A lightweight handle for lifting and transporting a heavy-duty container. The handle of the present invention includes a spring return mechanism for automatically storing the shank of the handle when not in use. A further feature of the present invention includes a stop mechanism for limiting the pivotal movement of the handle shank to approximately 90 degrees.
Claims30
A lightweight handle for lifting and transporting a heavy-duty container, comprising:
- a shank member having a hand-grip portion and a pair of pivoting arm members extending from said hand-grip portion, said shank member capable of being pivoted between a first inoperative position and a second operative position, and being returned automatically to said first inoperative position;
- a pair of bracket support members each comprising an elongated base plate and a pair of sidewalls extending therefrom;
- said pivoting arm members each having a respective distal end pivotally secured to said pair of respective bracket support members;
- a pair of pivot pin means each having an axis and two ends, each pivot pin means engaging at one end respective bracket support members to that said pivot pin means rotates about said pin axis, said one end of each pivot pin means fixedly engaged with respective distal ends of said arm members so that said shank member can pivot with respect to said bracket support members, and said other end of said pivot pin means located remotely from said bracket support members;
- and,
- spring means having two distal ends, one of said distal ends of said spring means engaging said bracket support members, the other of said distal ends of said spring means rotatable with said pivot means at said remote end, whereby said spring means will be wound up as said shank member is pivoted from said first inoperative position into said second operative position and, upon release of said shank member from said second operative position, said spring means will bias said shank member into said first inoperative position.
