Abstract
An exercise dumbbell includes a handle and weight plates maintained in spaced relationship relative thereto. At least one weight selector is movable into and out of engagement with different combinations of the weight plates to secure a desired amount of mass to the handle.
Claims27
A method of adjusting weight resistance to exercise, comprising the steps of:
- providing a weight lifting member having weight supports and defining a longitudinal axis;
- providing weights sized and configured to be supported by the weight supports;
- providing a weight selector having a first end portion sized and configured for insertion into less than all of the weights, and a relatively longer, second end portion sized and configured for insertion into a relatively greater number of the weights;
- and
- alternatively inserting the first end portion and the second end portion into respective weights to secure desired combinations of the weights to the lifting member.
2 more elements
An exercise dumbbell, comprising:
- a handle assembly that defines a longitudinal axis;
- weight supports secured to opposite ends of the handle assembly;
- weights sized and configured to be supported by the weight supports, including a first weight having an outwardly projecting tab that extends laterally in a first direction and defines a first hole, and a second weight having an outwardly projecting tab that extends laterally in an opposite, second direction and defines a second hole, wherein when the first weight and the second weight are axially aligned, each said tab is visible from each end of the longitudinal axis;
- and
- a weight selector configured for insertion through at least one of the weight supports, through the first hole, and alongside of the second weight, and alternatively, for insertion through at least one of the weight supports, alongside of the first weight, and through the second hole.
2 more elements
An adjustable weight exercise apparatus, comprising:
- a weight lifting member that defines a longitudinal axis;
- weight supports mounted on the weight lifting member;
- weights sized and configured to be supported by the weight supports;
- and
- a weight selector having a first end portion configured to select a first combination of the weights upon insertion into a passage defined by at least some of the weight supports, and having a second end portion configured to select a different, second combination of the weights upon insertion into the passage.
2 more elements
An exercise dumbbell, comprising:
- a handle that defines a longitudinal axis;
- weight supports mounted on opposite ends of the handle;
- weights sized and configured to be supported in respective, axially spaced positions defined by the weight supports;
- and
- a weight selector having a first end portion configured to span a first group of the weights upon insertion into a passage defined by at least some of the weight supports, and a relatively longer, second end portion configured to span a second group of the weights upon insertion into a passage defined by at least some of the weight supports.
2 more elements
An exercise dumbbell, comprising:
- a handle assembly having a handle that defines a longitudinal axis;
- first weight supports mounted on a first end of the handle assembly;
- second weight supports mounted on a second end of the handle assembly;
- first end weights configured to be supported in respective, axially spaced positions defined by the first weight supports, wherein the first end weights include a first weight, a second weight that weighs twice as much as the first weight, and a third weight that weighs three times as much as the first weight;
- second end weights configured to be supported in respective, axially spaced positions defined by the second weight supports, wherein the second end weights include a fourth weight, a fifth weight that weighs twice as much as the fourth weight, and a sixth weight that weighs three times as much as the fourth weight;
- and
- at least one weight selector configured to releasably connect different combinations of the weights to the handle assembly wherein the at least one weight selector is inserted through a first passage defined by the weight supports to select a first combination of the weights, and the at least one weight selector is alternatively inserted through a second passage defined by the weight supports to select a second combination of the weights.
