摘要:
A storing and transporting system for compact discs (“CD's”) for recorded audio materials and related accessory materials such as notebooks or booklets comprising an outside case of flat, clamshell configuration defining two storage areas, and one or two box-like disc containers of similar configuration to be nested in the storage areas and each having a tray-like body for holding a stack of discs in flexible storage envelopes. Guides and partitions in the case define the two storage areas and hold the stored items snugly therein, and the containers have removable retainers for holding a selected number of disc envelopes therein. Integral recessed latches hold the covers releasably in closed positions, and the case and the container are sized to receive and hold preselected numbers of discs and booklets of related materials so as to be highly versatile in use, and are provided with convenient label areas.
摘要:
Longitudinal and rotational movement of a rocking chair during the rocking motion is substantially prevented with a rocking chair having a pair of transversely-spaced, generally longitudinally extending rockers that converge at a first angle. A base is provided having a pair of transversely-spaced, generally longitudinally extending channels that converge at a second angle at least approximately the same as the first angle. The channels are positioned to underlie the rockers as the rocking chair is rocked. The transverse width of each channel is sufficiently wider than the transverse width of the respective rocker to accommodate the rocker within the channel during rocking motion of the chair, and is sufficiently narrower than the transverse width of the respective rocker to prevent substantial longitudinal movement of the rockers within the channels.
