    • A variable inertia bat weight training aid having a sleeve with radially divided, elongate pockets in which are permanently captured a plurality of weights. One end of the sleeve has a diameter sufficient to receive the barrel of a baseball bat but the other end of the sleeve includes a restricting band having a diameter sufficient to receive the handle of the bat but insufficient to pass over the barrel of the bat. Each weight within an associate pocket may be adjustably positioned along the length of the sleeve and secured in place by a restraining strap in order to vary the inertial resistance of the baseball bat and the perceived weight a batter experiences for warm-up and strength training exercises.
    • 一种可变的惯性蝙蝠重量训练辅助器具有一个具有径向分隔的细长口袋的套筒,其中永久地捕获多个重物。 套筒的一端具有足以容纳棒球棒的筒的直径,但是套筒的另一端包括具有足以容纳蝙蝠的手柄的直径的限制带,但不足以超过蝙蝠的桶。 联合口袋中的每个重量可以沿着套筒的长度可调节地定位并且通过限制带固定在适当位置,以便改变棒球棒的惯性阻力和用于预热和强度训练的感觉体重 。

    • A portable and collapsible storage container formed of rigid, interconnected panels which, when fully assembled, form a self-standing, integrally strong unit and, when collapsed, fold together to occupy a minimal volumetric space. Opposed side walls are hingedly connected to a front frame, and opposed end walls are hingedly connected to a rear wall panel, both to fold inwardly in interlocking fashion such that the side walls overlie the rear panel and the end walls overlie the side walls within the region bounded by the front frame. The storage container may optionally include a door or lid for closure which may be fitted with a lock if desirable. The side walls include means for supporting a removable interior panel to prevent the side walls from folding inwardly which, in turn, prevent the end walls from folding inwardly.
    • 一种便携式和可折叠的存储容器,由刚性的互连面板形成,当完全组装时,它们形成一个独立的,整体强大的单元,并且当折叠时折叠在一起以占据最小的容积空间。 相对的侧壁铰接地连接到前框架,并且相对的端壁铰接地连接到后壁板,两者以互锁的方式向内折叠,使得侧壁覆盖在后面板上,并且端壁覆盖在侧壁内 由前框架限定的区域。 存储容器可以可选地包括用于封闭的门或盖,如果需要,其可以装配有锁。 侧壁包括用于支撑可拆卸内部板以防止侧壁向内折叠的装置,这又防止端壁向内折叠。
