    • A selectorized dumbbell has a plurality of nested weights that provide a stack of left weight plates and a stack of right weight plates. A handle is dropped between the stacks and a selector is inserted into one of a plurality of vertically spaced positions on the handle to couple a selected number of the weights to the handle. The selector has a continuous periphery enclosing an open interior. A user who is exercising with the dumbbell will be alerted to unintended dislodgement of the selector since a portion of the selector's periphery will contact a portion of the user's grip hand, wrist or forearm during such dislodgement. This prevents complete dislodgement and prompts the user to restore the selector to a fully installed position. Side walls of the selector may become curved when the selector is installed to provide an additional frictional force resisting dislodgement of the selector.
    • 一个选择器化的哑铃具有多个嵌套的重物,这些嵌套的重物提供一叠左侧重物板和一叠右侧重物板。 手柄落在堆叠之间,并且选择器被插入到手柄上的多个垂直间隔位置中的一个上以将选定数量的配重连接到手柄。 选择器具有封闭开放内部的连续外围。 锻炼哑铃的使用者将被警告选择器意外移动,因为选择器的周边的一部分将在这种移动期间接触使用者的手部,手腕或前臂的一部分。 这可以防止完全移位并提示用户将选择器恢复到完全安装的位置。 选择器安装时,选择器的侧壁可能会弯曲,以提供额外的摩擦力,阻止选择器移位。
