Abstract

Abstract A distress and emergency signaling device which takes the form of a base member attached to a conventional photographic flash cube. The flash cube is of the type that does not require any electrical energy from an outside source. A base is attached to the flash cube. Within each base are a plurality of manually movable members with there being a separate member for each flash bulb of the flash cube. Operation of a movable member causes release and movement of a wire to strike a metallic rod connected to a particular flash bulb of the flash cube which causes flashing of the bulb.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 233 words
A distress and emergency signaling device comprising: a flash cube constructed of a plurality of flash bulbs, each said flash bulb being separately activatable by activation means, said flash cube being polygonal shaped forming four in number of sides, there being a separate flash cube for each said side, said activation means for each said bulb comprising a cocked member under a continuous spring bias; and a base fixedly attached to said flash cube, said base having a cross-sectional size substantially equal to the cross-sectional size of said flash cube, said base including manually operable actuation means, said actuation means comprises a separate actuation member for each said flash bulb with there being four in number of said actuation members, each said actuation member to connect with a separate said cocked member, each said actuation member being slidably mounted for lineal movement within a groove formed within a said base with there being a separate said groove for each said actuation member, said lineal movement for each said actuation member being directly in line with its respective said flash bulb, each said groove being sufficiently recessed so each said actuation member is totally recessed within said base to prevent accidental operation of said actuation members, upon manual operation of a said actuation member the said cocked member for the respective said flash bulb is activated which causes flashing of the said flash bulb.
Claim 2
Dependent Claim 233 words
A distress and emergency signaling device comprising: a flash cube constructed of a plurality of flash bulbs, each said flash bulb being separately activatable by activation means, said flash cube being polygonal shaped forming four in number of sides, there being a separate flash cube for each said side, said activation means for each said bulb comprising a cocked member under a continuous spring bias; and a base fixedly attached to said flash cube, said base having a cross-sectional size substantially equal to the cross-sectional size of said flash cube, said base including manually operable actuation means, said actuation means comprises a separate actuation member for each said flash bulb with there being four in number of said actuation members, each said actuation member to connect with a separate said cocked member, each said actuation member being slidably mounted for lineal movement within a groove formed within a said base with there being a separate said groove for each said actuation member, said lineal movement for each said actuation member being directly in line with its respective said flash bulb, each said groove being sufficiently recessed so each said actuation member is totally recessed within said base to prevent accidental operation of said actuation members, upon manual operation of a said actuation member the said cocked member for the respective said flash bulb is activated which causes flashing of the said flash bulb.
Claim 3
Dependent Claim 35 words
The signaling device as defined in claim 1 wherein: each said actuation member being biased into snug contact with the walls of its respective said groove, whereby undesired sliding movement of said members is prevented.
