Abstract
An exercise dumbbell includes a handle member and weights positioned at opposite ends of the handle member. An additional weight forms a box about the handle member and the end weights. At least one weight selector is movably mounted on the handle member to selectively engage the end weights. At least one connector is movably mounted on the box weight to selectively engage the handle member. A circuit includes at least one sensor that generates a signal that represents how much force is required to lift the handle member and any weights secured thereto, and a display that displays the force. At least one latch prevents movement of the selector and/or the connector when the handle member is removed from a support base for the weights and the handle member.
Claims24
An exercise dumbbell, comprising:
- a first set of weights;
- a second set of weights;
- and
- a handle assembly disposed between the first set of weights and the second set of weights, wherein each of the weights in the first set wraps around a first end of the handle assembly, and each of the weights in the second set wraps around an opposite, second end of the handle assembly, wherein the handle assembly includes at least one selector for movement into and out of underlying engagement with the weights.
An exercise dumbbell, comprising:
- a first set of weights;
- a second set of weights;
- and
- a handle assembly disposed between the first set of weights and the second set of weights, wherein the handle assembly includes (a) at least one selector for movement into and out of underlying engagement with the weights;
- (b) at least one sensor for sensing which said weights said at least one selector is currently underlying;
- and (c) an electronic display operatively connected to said at least one sensor for displaying a weight amount based on the weight of the handle assembly and which said weights said at least one selector is currently underlying.
An exercise dumbbell, comprising:
- a first set of weights;
- a second set of weights;
- a handle assembly disposed between the first set of weights and the second set of weights, and including at least one selector for movement into and out of underlying engagement with the weights;
- and
- a box-shaped weight disposed about the first set of weights and the second set of weights, wherein a connector on the box-shaped weight is movable into and out of underlying and overlying engagement with the handle assembly.
An exercise dumbbell, comprising:
- a first set of weights;
- a second set of weights;
- a handle assembly disposed between the first set of weights and the second set of weights, wherein the handle assembly includes (a) a first end disposed adjacent the first set of weights;
- (b) a second end disposed adjacent the second set of weights;
- (c) a hand grip interconnected between the first end and the second end;
- and (d) at least one selector for movement into and out of underlying engagement with the weights;
- and
- a hand grip supplement releasably connected to the handle assembly directly beneath the hand grip, wherein the hand grip supplement cooperates with the hand grip to provide a relatively larger, second hand grip having a discrete profile as compared to the hand grip.
An exercise dumbbell, comprising:
- a first set of weights;
- a second set of weights;
- a base having a first end sized and configured to support the first set of weights, and a second end sized and configured to support the second set of weights, and an upwardly facing bearing surface;
- and
- a handle assembly disposed between the first set of weights and the second set of weights, wherein the handle assembly includes (a) at least one selector for movement into and out of underlying engagement with the weights;
- (b) a member that aligns with and engages the bearing surface when the handle assembly is resting on the base;
- and (c) an electronic display operatively connected to the member, wherein the display presents a first visible signal to indicate that a person may safely operate the selector, because the handle assembly is resting on the base, and the display alternatively presents a second visible signal to indicate that it is unsafe for a person to operate the selector, because the handle assembly is removed from the base.
