1. An exercise dumbbell, comprising:
- a handle member having a first weight supporting section, a second weight supporting section, and a handle that extends therebetween and defines a longitudinal axis, wherein each said weight supporting section has an axially measured length that is bounded by a respective inner end and a respective outer end;
first weights sized and configured to be supported by the first weight supporting section;
second weights sized and configured to be supported by the second weight supporting section; and
a first weight selector associated with the first weight supporting section and the first weights, and a second weight selector associated with the second weight supporting section and the second weights, wherein each said weight selector is movably mounted on the handle member and movable between a respective first latched position, disposed entirely outboard from a respective inner end, and a respective second latched position, disposed entirely inboard from a respective outer end, displaced axially relative to a respective first latched position, and engaging a different combination of respective weights.

Abstract
An exercise dumbbell includes a handle member and weight plates maintained in spaced relationship at opposite ends thereof. Weight selectors are movable into and out of engagement with different combinations of the weight plates to secure a desired amount of mass to the handle. The weight selectors are preferably nested within respective ends of the handle member and accessible via upwardly opening slots in the weight plates.

6. An exercise dumbbell, comprising:
-
a handle member having a first weight supporting section, a second weight supporting section, and a handle that extends therebetween and defines a longitudinal axis, wherein each said weight supporting section includes an axially extending bar; first weights sized and configured to be supported by the first weight supporting section, wherein each of the first weights has an upwardly opening slot that accommodates a respective said bar; second weights sized and configured to be supported by the second weight supporting section, wherein each of the second weights has an upwardly opening slot that accommodates a respective said bar; a first weight selector and a second weight selector, wherein each said weight selector is movably mounted on a respective end of the handle member, and is configured and arranged to selectively engage at least one of the weights associated therewith, and to span at least one other of the weights associated therewith without underlying any portion of said at least one other of the weights; and a first operator member and a second operator member, wherein each said operator member is connected to a respective weight selector and extends upward through at least one said slot in the weights associated therewith. - View Dependent Claims (7, 8, 9, 10)

11. An exercise dumbbell, comprising:
-
a handle member having a handle that defines a longitudinal axis, and axially spaced weight supports disposed at opposite ends of the handle; first weight plates sized and configured to be supported by respective weight supports at a first end of the handle member, including an innermost first weight plate having an innermost surface that faces toward the handle, and an outermost first weight plate having an outermost surface that faces away from the handle; a first weight selector movably mounted on the handle member and movable axially to a position disposed entirely between the innermost surface on the innermost first weight plate and the outermost surface on the outermost first weight plate, and underlying at least one of the first weight plates but less than all of the first weight plates; second weight plates sized and configured to be supported by respective weight supports at a second end of the handle member, including an innermost second weight plate having an innermost surface that faces toward the handle, and an outermost second weight plate having an outermost surface that faces away from the handle; and a second weight selector movably mounted on the handle member and movable axially to a position disposed entirely between the innermost surface on the innermost second weight plate and the outermost surface on the outermost second weight plate, and underlying at least one of the second weight plates but less than all of the second weight plates. - View Dependent Claims (12, 13, 14, 15)

16. An exercise dumbbell, comprising:
-
a handle member having a first weight supporting section, a second weight supporting section, and a handle that extends therebetween and defines a longitudinal axis; first weights sized and configured to be supported by the first weight supporting section; a first weight selector confined to the first weight supporting section and selectively movable in a first direction to engage only a first subset of the first weights; a second weight selector confined to the first weight supporting section and selectively movable in an opposite, second direction to engage only a second, complementary subset of the first weights; second weights sized and configured to be supported by the second weight supporting section; a third weight selector confined to the second weight supporting section and selectively movable in said first direction to engage only a first subset of the second weights; and a fourth weight selector confined to the second weight supporting section and selectively movable in said second direction to engage only a second, complementary subset of the second weights. - View Dependent Claims (17, 18, 19, 20)
