Abstract

Abstract A device capable of being mounted on a horizontal surface of a motor vehicle includes a vertical support for exhibiting interchangeable emergency signs, the support having a leg member mounted thereon for movement into a support stabilizing position about a vertical axis. The signs are slid into place along tracks each having constricted openings for preventing the sign from inadvertently sliding outwardly therefrom.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 295 words
A device capable of being mounted on a horizontal surface of a motor vehicle for exhibiting emergency signs, comprising a flat and elongated upstanding support member for the signs, said support member including at least one pair of elongated open channels facing inwardly toward one another along which the signs may be slid into place, said member further including an imperforate end plate at one end thereof extending across said channels, said member also including an end plate at the opposite end thereof extending across said channels and covering an end of a lower one of said channels for preventing the signs from inadvertently sliding outwardly of said channels, said opposite end plate having an opening therein through which the signs may be inserted, said member further including an elongated screw trough disposed along a lower edge thereof, and an elongated leg member mounted between its opposite ends to said lower edge for pivotal movement about an axis perpendicular thereto by means of a threaded fastener extending through said leg member and threadedly engaging said screw trough, said leg member being pivotable between a position of non-use lying in the plane of said support member and a position of use extending outwardly of opposite sides of said support member, said leg member having a length not greater than the length of said support member, and said fastener being so disposed relative to said leg member opposite ends and relative to said ends of said support member as to permit said leg member to be pivoted into its position of nonuse without extending outwardly of said end plates of said support member, and suction cups being mounted to said support member at said lower edge thereof and to said leg member at said opposite ends thereof.
