Abstract: The disclosure concerns an inner duty belt and related system. The inner duty belt has an inner side and an outer side, and includes a waist portion having a first touch fastener coupled to the outer side, an attachment portion having a connecting element configured to engage with the waist portion, and a flexible portion disposed between the waist portion and the attachment portion. The flexible portion is configured to fold upon convergence of the waist and attachment portions. The flexible portion of the inner duty belt allows the inner duty belt to easily increase and decrease in circumference while engaged with an outer duty belt.

Abstract: A baseball practice system for training one in pitching, throwing, fielding, catching, and batting. The practice system is portable and collapsible having a removable pitching component on one side and a batting and netting on the other side. The pitching component has a strike-zone opening and one or more pockets in a catch sack in back of the strike-zone opening. The netting is of an elastic material suited to rebound a ball thrown on the netting for the purpose of practicing throwing, catching, and fielding. A ball component, attached to elastic cords, is suspended outward and downward from a forward extending member adjacent to the top of the baseball practice system. An adjustment and locking member adjacent to the rear of the forward extending member adjustably secures in place an upper cord which is attached to a ball.

Abstract: A hingedly collapsible batting practice device with a top v-shaped component hingedly connected to two side members and supportable in an approximate horizontal orientation. A rear member attaches to the top of each side member. A bottom v-shaped component hingedly connected to the two side members with a support member for supporting the two side members in an approximate vertical orientation. Each v-shaped component is also hinged at the front to permit each side of the component to pivot toward each other to facilitate collapsing the device. An elastic cord attached to the rear member extends frontward and downward from the top v-shaped component and supports a ball at its terminal end. A non-elastic cord is attached to the ball and each loose end of the non-elastic cord is attached to the bottom v-shaped component.
