Adjustable dumbbell system
DCFirst Claim
1. An adjustable dumbbell system, comprising:
- (a) a dumbbell comprising;
(i) a handle;
(ii) an inner support mounted on the handle and substantially fixed relative to the handle;
(iii) an inner disc rotatably mounted on the handle;
(iv) a plurality of intercoupled collars each including at least one flange, the plurality of intercoupled collars being further intercoupled with the inner disc;
(v) a rotational interference device for coupling the inner disc to the inner support;
(vi) a selector device intercoupled with the plurality of intercoupled collars and the inner disc; and
(b) a base support comprising;
(i) a plurality of weights, each weight having a tab;
(ii) a plurality of positioning walls for supporting the weights; and
(iii) an actuator for releasing the rotational interference device, whereby some combination of the plurality of weights are selected by engaging the at least one flange of at least one of the collars with the tab of the weight.

Abstract
A dumbbell is described including a handle having a grip and at least one end, an inner plate mounted on the handle adjacent the grip, in a fixed rotational orientation, a support plate rotationally mounted on the handle adjacent the inner plate, at least one collar rotationally mounted on the handle adjacent the support plate, and rotationally fixed with the support plate, a selector knob rotationally mounted on the handle adjacent the at least one collar, and rotationally fixed with the collar, a weight plate removably mounted on the handle adjacent the at least one collar, and a means for selectively securing the support plate to the inner plate to resist the rotation of the support plate, collar and selector knob with respect to the inner plate and handle.

6. A dumbbell and base system comprising:
-
a variable weight dumbbell having at least one weight plate, and having means for selecting the at least one weight plate on the dumbbell to provide the desired weight load, and means for disabling said means for selecting; a base for receiving said dumbbell; means for selectively securing said dumbbell in said base when said means for selecting is not fully engaged; and wherein said means for selecting is operable only when said dumbbell is positioned in said base and said means for disabling is actuated only when said dumbbell is removed from said base. - View Dependent Claims (7, 8)

23. A dumbbell and base system comprising:
-
a variable weight dumbbell comprising; at least one weight plate; a selection device operably associated with the at least one weight plate to provide a desired weight load; and a locking device operably associated with the selection device to disable the selection device; a base for receiving said dumbbell comprising; at least one protrusion selectively operable with the selection device to secure the variable weight dumbbell to the base when the selection device is not fully engaged; wherein the selection device is operable only when the dumbbell is positioned in the base, and the locking device is actuated only when the dumbbell is removed from the base. - View Dependent Claims (24, 25)
