  • Device to automatically roll up bands
    Patent number: 5996923
    Abstract: The present invention automatically rolls up bands, such as curtains, sunshades and mobile panes. The present invention consists of a tubular structure which incorporates in its interior a spindle with two sections threaded in opposite directions acting, thorough rotation, upon corresponding mobile structures on each side, displacing them and causing a compression or traction of a spring placed between them. The tubular structure has in its interior side longitudinal protuberances, which fit into corresponding slits of the mobile structures, thus rotating as they move.
