  • Patent number: 10603993
    Abstract: Apparatus and associated methods relate to a storage container and storage container lid configured for stowage and extraction of panels, the panels having complementary mating interfaces that cause the panels to stack onto one another as the panels enter the storage container lid, and to couple to one another as the panels are extracted from the storage container lid. In an illustrative example, the mating interface for the panels may include a first linearly decreasing section, a linearly increasing section, and a second linearly decreasing section that complements the mating interface of an adjacent panel. The panels may slide along a channel into and out of an opening in the storage container lid. A panel storage system may advantageously store panels in the lid of the storage container, while still providing access to the contents of the storage container by opening of the lid.

  • Publication number: 20020084041
    Abstract: An aperture, covering including track-guided interconnectable panels that are compactly stored in a storage area containing weight counterbalancing mechanisms, such as a compressed spring, is described. When the panels are stacked in the storage area and removed one at a time, the first panel is removed from the storage area and enters the track. As the first panel moves through the track, it interlocks with the second panel and forces the second panel out of the storage area and into the track. Interlocking and removal of the panels continues until all of the panels are removed or the first panel reaches the end of the track. Weight counterbalancing can be assisted by track-contained mating mechanisms, cable and ball drive mechanisms, or other counterbalancing methods. The resulting aperture covering requires minimal storage space for the open aperture position, minimizes exposure to potentially hazardous counterbalancing mechanisms, and allows for heavy-weight panel construction.
