Vehicular device displaying visible message to following driver - affords choice of messages by rotation of elongated drum in transparent housing with low profile

摘要

A housing (1) extending across the width of the rear window, but not high enough to impair the driver's rearward vision, encloses a hexagonal drum (3) which is rotated about its axis (4) by a belt (6) driven by a roller (5') in the corner of the housing. Each facet (F) of the drum (3) may carry a different message or appeal for the attention of the driver of a following vehicle. The chosen display is positioned by a control on the dashboard. ADVANTAGE - Directions or calls for assistance can be given in clearly visible and quickly recongisable form.
