Emergency signal

An emergency signal comprising:

• a base;
• signalling means spaced from said base and including high intensity flash lamp means;
• window means in said signalling means adjacent said high intensity flash lamp means;
• a DC power source for energizing said flash lamp means;
• actuating means in said base electrically connected through switch means to power source, said high intensity light flashes being visible through said window means when said switch means is closed;
• storage capacitor means connected across said flash lamp means;
• means connected to said flash lamp means for triggering said flash lamp means into conduction;
• oscillator means coupled to said source of DC power;
• a DC/AC inverter connected to the output of said oscillator means and to said DC power source;
• an AC/DC converter and voltage multiplier connected between said DC/AC inverter and said storage capacitor means;
• a feedback network;
• comparator means connected between said feedback network and said oscillator;
• and
• means for coupling the voltage output from said voltage multiplier to said feedback network, said comparator means actuating said oscillator means when a predetermined reduction in the voltage on said storage capacitor means is detected;
• whereby said storage capacitor means is maintained at a desired voltage level sufficient to actuate said flash lamp means as desired.

An emergency signal comprising:

• a base member;
• at least one plural-sided telescoping box deployable from a stored mode nested within said base to an extended mode;
• detent means for releasably retaining said box in the extended mode;
• said box having a light-transmitting symbol on at least one side thereof;
• means inside said box for illuminating the respective symbol thereon;
• a top attached to said box when in the extended mode;
• and
• latch means for latching said top to said base with said box inside to define a self-contained container when not in use.

An emergency signal comprising:

• a base member;
• a light transmissive top rotatably mounted to said base member;
• high intensity flash lamp means within said top;
• a DC power source comprising battery means mounted in said base member;
• and
• lamp control means mounted in said base member;
• said top having a plurality of operative positions, the signal being in a quiescent state when said top is in a first position, said battery means being accessible for removal from said base member when said top is in a second position, and said lamp being actuated when said top is in a third position.

An emergency signal comprising:

• a base member;
• at least one second member telescopically connected to said base member, said base member and said second member being together in a stored mode and being separated in an operative mode;
• means for releasably retaining said base member and said second member in the stored mode;
• at least one of said base member and said second member having a light transmissive surface on at least one side thereof;
• means inside said one member for illuminating said light transmissive surface;
• and
• control means for actuating said illuminating means.

An emergency signal comprising:

• a housing formed with at least two triangular surfaces;
• light transmissive window means in at least one of said surfaces;
• means for supporting said housing on a substantially flat surface;
• a high intensity lamp within said housing positioned so as to be visible through said window means;
• lamp control means mounted in said housing.
