Apparatus for prevention of key locked in car
First Claim
1. An apparatus for generating an alarm corresponding to a person egressing a compartment through a doorway while leaving an article behind, comprising:
- a sensing means mounted adjacent the doorway;
a sensed element carried by the person through the doorway;
a shielding element adapted to coact with the sensed element for preventing the sensed element from being sensed by said sensing means, said shielding element having means applied thereon for connecting said article to said shielding element; and
wherein said article comprises an ignition key for a car, and said compartment comprises an automobile.

Abstract
A method and apparatus for preventing a person from leaving an enclosed space having a door while leaving an article behind, such as preventing a driver from leaving an automobile while leaving the ignition keys within the automobile. Sensing elements are mounted on opposite sides of the door and a sensing device is located with the person. A shield which is adapted to cover the sensed element is attached to the ignition key. When the driver leaves the car without the ignition key, and without the shield covering the sensed element, the sensing device sounds an audible or visual alarm.

8. A method for preventing unintentional egress from a vehicle while leaving the ignition key within the vehicle, comprising the steps of:
-
providing a sensing device adjacent a vehicle door; providing a first part which can be sensed by said sensing device to be retained by a driver of the vehicle; and providing a second part connected to said ignition key, said second part fashioned to shield said first part from said sensing device; causing said sensing device to activate an alarm when said first part egresses with the driver past the sensing device without being shielded by said second part.

9. An apparatus for preventing unintentional egress from a vehicle while leaving the ignition key within the vehicle, comprising:
-
a sensing device mounted adjacent a door of the vehicle; an alarm device operatively connected to said sensing device to be activated by said sensing device for generating a user recognizable alarm; a first part which is sensed by said sensing device upon departing the vehicle when not shielded by a second part to activate said alarm device to generate a user recognizable alarm, and retained by an operator of the vehicle; a second part connected to an ignition key of the vehicle, said second part fashioned to shield said first part from said sensing device. - View Dependent Claims (10, 11)
