Patent ID: 7497813

Claim:
A method of adjusting weight on a selectorized dumbbell, comprising the steps of: providing a handle assembly having a handle that defines a longitudinal axis, a first weight supporting section at a first end of the handle, a second weight supporting section at an opposite, second end of the handle, a first weight selector that is movable along the first weight supporting section, and a second weight selector that is movable along the second weight supporting section; providing a first weight and a second weight to occupy respective positions defined by the first weight supporting section, wherein the first weight defines an upwardly closed opening configured and arranged to accommodate the first weight selector, and the second weight defines an upwardly open notch configured and arranged to accommodate the first weight selector; selectively moving the first weight selector between a first latched position, spanning only the first weight and thereby preventing upward movement of the handle assembly relative to the first weight, and a second latched position, spanning only the second weight and thereby freeing the handle assembly for upward movement relative to both the first weight and the second weight; providing a third weight and a fourth weight to occupy respective positions defined by the second weight supporting section, wherein the third weight defines an upwardly closed opening configured and arranged to accommodate the second weight selector, and the fourth weight defines an upwardly open notch configured and arranged to accommodate the second weight selector; and selectively moving the second weight selector between a first latched position, spanning only the third weight and thereby preventing upward movement of the handle assembly relative to the third weight, and a second latched position, spanning only the fourth weight and thereby freeing the handle assembly for upward movement relative to both the third weight and the fourth weight.
