Alarm systems for automotive vehicles
First Claim
1. An alarm system for automotive vehicles having a horn and a source of electrical power comprising:
- front and rear indicator lamps;
a power activating and deactivating switch connected to said source of electrical power and switchable between system activated and system inactivated positions;
a system activating means inter-connected to said power activating and deactivating switch;
an activated alarm system maintaining means associated with said system activating means;
an alarm system inactivating means associated with said source of electrical power and said system activating means for inactivating said alarm system when said source of electrical power is at a predetermined voltage level; and
a plurality of parallel connected switching means associated with vehicle movable structural panels switchable between off and on positions by the opening and closing respectively of said panels, whereby when said power activating and deactivating switch is in said system activated position and at least one of said plurality of parallel connected switching means is repositioned from an off to an on position said system activating means activates said alarm system causing said horn to intermittently blast and when said at least one of said plurality of parallel connected switching means is returned to its off position said activated alarm system maintaining means causes said horn to intermittently blast until said power activating and deactivating switch is returned to its deactivated position or said source of electrical power reaches said predetermined voltage level.

Abstract
An alarm system for an automotive vehicle. In one embodiment the opening of selected movable vehicle structural panels when the alarm is activated causes intermittent operation of the vehicle brake lights, front turn signal lights and the blasting of the vehicle horn. In a second embodiment the opening of selected movable vehicle structural panels when the alarm is activated causes intermittent operation of the vehicle parking lights front and rear, the blasting of the vehicle horn and includes an indicator for determining the on or off status of the parking lamps from within the vehicle. In both embodiments diodes are used to allow normal operation of the hazard lamps, turn signal, horn and parking lamps of the vehicle without activating the alarm system.

8. An alarm system for automotive vehicles having front and rear turn signal lamps operated either by a turn signal indicator, hazard warning or brake switch circuits, a horn and a source of electrical power comprising:
-
a single pole-single throw, anti-theft switch having first and second connections, said first connection connected to said source of electrical power; an arming relay having an input and output, said input is connected to said second connection of said anti-theft switch; a holding relay interconnected to said output of said arming relay and said second connection of said anti-theft switch; a flasher element having an input and output connection, said input connection connected to the output of said anti-theft relay; a plurality of parallel connected mechanical switching means associated with the vehicle access panels, switchable between on and off positions, whereby when said anti-theft switch is in a position to connect said source of electrical power to said arming and holding relay and at least one of said plurality of parallel connected mechanical switching means is switched from an open to a closed state by the opening of its associated vehicle access panel, said arming relay activates, supplying said source of electrical power to the input of said flasher element causing said horn to be intermittently activated and deactivated and when said at least one of said plurality of parallel connected switching means is returned to its off position, said holding relay causes said arming relay to remain activated until said anti-theft switch is returned to a position wherein the electrical power is removed from said holding relay. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
