Today’s invention attempts to overcome the problem of placing baggage items on an overhead location in public transport.
Often I see people struggling to achieve this, either because the bag is too heavy, or they can’t manage to squat and thrust it into place without endangering people sitting below.
A curved shelf section would be installed at frequent intervals along a carriage/compartment/cabin. A cable would run from a catch attached to the shelf to a pulley in the ceiling.
Attaching bags to a hook on the upper end of the cable would allow them to be hoisted aloft and secured there, without causing a safety issue for those seated below. Use of extra pulleys would increase the mechanical advantage available. The slight slope of the shelf would allow the baggage items to descend later under control.
