Patent ID: 8668630

Claim:
An add-on weight kit for a selectorized dumbbell having a first set of a plurality of nested weights that include a plurality of horizontal rails that overlie one another in at least one vertically extending rail array, a first handle having an array of vertically spaced openings that are aligned with spaces below the rails in the rail array, and a selector comprising a connecting pin that includes at least one connecting prong that is horizontally insertable into one of the vertically spaced openings on the handle to slide below the rail of a selected weight to thereby couple the selected weight and all other weights whose rails lie above the rail of the selected weight to the handle, wherein the add-on weight kit comprises: (a) a second set of a plurality of nested weights that include a plurality of horizontal rails that overlie one another with the rails of the second set being arranged to underlie the rails of the first set to form a downward continuation of the rail array of the first set when the first and second sets of weights are used together; (b) a second handle that is physically separate and distinct from the first handle, that is taller than the first handle, and that can be alternatively used in place of the first handle only by removing the first handle from the selectorized dumbbell and by inserting the second handle into the selectorized dumbbell in place of the first handle, wherein the second handle has a bottom portion that includes a plurality of vertically spaced openings that are aligned with spaces below the rails of the second set of weights for reception of the connecting prong in the same manner as the connecting prong is received in the openings on the first handle, wherein the second handle is used in place of the first handle when the first and second sets of weights are used together such that reception of the connecting prong below the rail of a selected weight in the second set of weights will couple the selected weight in the second set, all other weights in the second set whose rails lie above the rail of the selected weight in the second set, and all of the weights of the first set to the handle to thereby allow the total weight of the dumbbell to exceed what would have been obtainable from the first set of weights alone; and (c) wherein the weights of the first set of weights have a first uniform height relative to one another, wherein the weights of the second set of weights have a second uniform height relative to one another with the second uniform height being greater than the first uniform height such that the weights of the second set of weights will rest on a horizontal support surface while the weights of the first set of weights will be elevated above the support surface when the second handle is coupled to the first set of weights and at least one of the weights of the second set and the dumbbell is laid down on the support surface.
