Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
In a motor vehicle electrical system including an ignition switch having a plurality of positions selectively operable by an actuating mechanism on a longitudinally movable actuator bar, the improvement comprising: a. at least two solenoids having rams with a common longitudinal axis; b. a T-shaped locking member having two opposed legs and a third leg normal thereto; c. one said solenoid being attached to one said opposed leg and being operative to move said T-shaped blocking member to a first position wherein the said third leg prevents longitudinal movement of said actuator bar to at least one of the positions of said ignition switch; d. a second said solenoid being attached to the other of said opposed legs and being operative to move said T-shaped blocking member to a second position wherein the actuator bar is unobstructed of longitudinal movement by said third leg; and e. means for operating each said solenoid independently of the other.
Claim 2
Dependent Claim
156 words
In a motor vehicle electrical system including an ignition switch having a plurality of positions selectively operable by an actuating mechanism on a longitudinally movable actuator bar, the improvement comprising: a. at least two solenoids having rams with a common longitudinal axis; b. a T-shaped locking member having two opposed legs and a third leg normal thereto; c. one said solenoid being attached to one said opposed leg and being operative to move said T-shaped blocking member to a first position wherein the said third leg prevents longitudinal movement of said actuator bar to at least one of the positions of said ignition switch; d. a second said solenoid being attached to the other of said opposed legs and being operative to move said T-shaped blocking member to a second position wherein the actuator bar is unobstructed of longitudinal movement by said third leg; and e. means for operating each said solenoid independently of the other.
Claim 3
Dependent Claim
48 words
The ignition switch of claim 1 wherein said ignition switch has ''''accessory,'''' ''''lock,'''' ''''off,'''' ''''on,'''' and ''''start'''' positions in that order and wherein the locking member when in its first position prevents movement of the actuating mechanism of the actuator bar into the ''''off,'''' ''''on,'''' and ''''start'''' positions.
Claim 4
Dependent Claim
28 words
The ignition switch of claim 2 wherein the locking member in the first position prevents movement of the actuating mechanism of the actuator bar from the ''''lock'''' position.
Claim 5
Dependent Claim
25 words
The ignition switch of claim 2 further comprising signalling switch means operative when the actuating mechanism of the actuator bar is in the ''''off'''' position.
Claim 6
Dependent Claim
48 words
The ignition switch of claim 1 wherein the actuator bar moves through a gate when it is unobstructed and wherein the said third leg is operative to block said gate and prevent longitudinal movement of said actuator bar through said gate when said one said solenoid is activated.
