  • Patent number: 9700775
    Abstract: A sports swing trainer includes a gripping portion configured to enable a user to grasp the trainer while in a batting stance, an arm positioning portion, and an alignment portion connecting the other two portions together. The arm positioning portion includes parts that simultaneously engage with a top of the shoulder and a brachium of the user when in a proper batting stance, and the arm positioning portion provides tactile feedback reminding the user to begin a swinging motion with hip and leg movements rather than arm movements. The alignment portion may include one or more joints that enable custom positioning of the gripping portion and the arm positioning portion to suit the training needs of many different users. The sports swing trainer provides an easy to manufacture solution for baseball/softball bat swing training which focuses on the mechanics of the swing rather than ball placement and contact.
