Selectorized dumbbell using commodity weights
First Claim
1. An adjustable dumbbell, comprising:
- (a) a handle including a grip;
(b) a plurality of weights, wherein each weight comprises;
(i) a pair of carriers;
(ii) at least one interconnecting member extending between the carriers and joining the carriers together in longitudinally spaced apart relationship with the carriers and interconnecting member(s) of each weight being separate and distinct from the carriers and interconnecting member(s) of the other weights and from the handle, wherein the carriers of different weights are longitudinally spaced apart at progressively greater distances to allow the carriers to be disposed in a nested and stacked arrangement with respect to one another; and
(iii) a weight plate removably attached to each carrier.

Abstract
This invention relates to a selectorized dumbbell having a handle that can be dropped down between nested left and right stacks of weight plates. The weight plates can comprise individual weights or a pair of weight plates, one from each stack, can be connected together to form a single weight. A selector is provided to allow the user to select a desired number of weight plates from each stack and couple such weight plates to the handle to provide an adjustable weight dumbbell. Each weight includes a weight frame having at least one carrier to which a commodity weight can be fastened. The dumbbell can be shipped by the manufacturer with empty weight frames to reduce shipping costs. When the dumbbell with empty weight frames reaches a destination, the dumbbell can be completed by securing commodity weights to the carriers on the respective weight frames.

11. A selectorized dumbbell, which comprises:
-
(a) a handle; (b) a plurality of weights that can be nested together forming a nested first stack of weight plates and a nested second stack of weight plates, the first and second stacks of weight plates being separated by a gap that is large enough to accommodate at least a portion of the handle therebetween; (c) a selector movable by the user between different positions to allow a desired number of weight plates from each of the first and second stacks to be coupled to either end of the handle when the handle portion is located in the gap between the first and second stacks and the selector is manipulated by the user; and (d) wherein each weight comprises; (i) a weight frame that includes at least one vertically extending carrier; and (ii) a weight plate having a central hole, wherein the weight plate is removably secured to the carrier of the weight frame; and (iii) wherein the carrier includes a cylindrical hub received in the central hole of the weight plate such that the weight plate is concentrically received around the cylindrical hub of the carrier when the weight plate is removably secured to the carrier. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A selectorized dumbbell, which comprises:
-
(a) a handle; (b) a plurality of weights that can be nested together forming a nested first stack of weight plates and a nested second stack of weight plates, the first and second stacks of weight plates being separated by a gap that is large enough to accommodate at least a portion of the handle therebetween; (c) a selector movable by the user between different positions to allow a desired number of weight plates from each of the first and second stacks to be coupled to either end of the handle when the handle portion is located in the gap between the first and second stacks and the selector is manipulated by the user; and (d) wherein each weight comprises; (i) a weight frame that includes at least one vertically extending carrier; (ii) at least one commodity weight which comprises a cast iron weight plate of the type having a central hole that can be slipped onto a bar of a non-selectorized barbell or dumbbell; (iii) a fastener for removably holding the commodity weight to the carrier on the weight frame to allow the commodity weight to be used on the selectorized dumbbell. - View Dependent Claims (19)

20. A selectorized dumbbell, which comprises:
-
(a) a handle; (b) a plurality of weights that can nested together forming a nested first stack of weight plates and a nested second stack of weight plates, the first and second stacks of weight plates being separated by a gap that is large enough to accommodate at least a portion of the handle therebetween; (c) a selector movable by the user between different positions to allow a desired number of weight plates from each of the first and second stacks to be coupled to either end of the handle when the handle portion is located in the gap between the first and second stacks and the selector is manipulated by the user; and (d) wherein each weight comprises; (i) a weight frame; and (ii) at least one commodity weight which comprises a cast iron weight plate of the type having a central hole that can be slipped onto a bar of a non-selectorized barbell or dumbbell; and (iii) a fastener for removably holding the commodity weight on the weight frame to allow the commodity weight to be used on the selectorized dumbbell, wherein the fastener comprises a tie for tying the commodity weight to the weight frame.

21. A selectorized dumbbell, which comprises:
-
(a) a handle; (b) a plurality of weights that can be nested together forming a nested first stack of weight plates and a nested second stack of weight plates, the first and second stacks of weight plates being separated by a gap that is large enough to accommodate at least a portion of the handle the therebetween; (c) a selector movable by the user between different positions to allow a desired number of weight plates from each of the first and second stacks to be coupled to either end of the handle when the handle portion is located in the gap between the first and second stacks and the selector is manipulated by the user; and (d) wherein each weight comprises; (i) a weight frame that includes a portion that coacts with the selector to determine if the weight is coupled to the selector or not; (ii) a carrier on one end of the weight frame, wherein the carrier has a vertically projecting portion that extends substantially vertically beyond the selector coacting portion of the weight frame; and (iii) a weight plate removably secured to the vertically projecting portion of the carrier.

22. A method of providing a selectorized dumbbell to a user located in a destination remote from a manufacturer of the dumbbell, which comprises:
-
(a) manufacturing a selectorized dumbbell having a handle, a selector, and a plurality of weight frames for providing a plurality of weights that can be nested together forming a nested first stack of weight plates and a nested second stack of weight plates, the first and second stacks of weight plates being separated by a gap that is large enough to accommodate at least a portion of the handle therebetween, each weight frame having at least one carrier for securing to the weight frame a commodity weight of the type comprising a cast iron weight plate having a central hole therethrough with the commodity weight being of the type that can be slipped onto a bar of a non-selectorized barbell or dumbbell; and (b) completing the weights of the non-selectorized dumbbell by removably attaching commodity weights of the type described above to the carriers provided on the respective weight frames. - View Dependent Claims (23)
