Claim 5

In a motor vehicle having an ignition lock and a parking brake, a stationary member, a parking brake operating member movably mounted on the stationary member and having a normal retracted position and being movable in one direction from the normal position to apply the parking brake and movable in the other direction from the normal position to release the parking brake, the improvement comprising; a cam surface and a shoulder in laterally and longitudinally spaced relation on the parking brake operating member, toggle means pivotally mounted on the stationary member, spring means biasing the toggle means to a normal position, plunger means operatively connected to the ignition lock and being movable within the stationary member in response to movement of the ignition lock between first and second positions, the toggle means engaging the plunger means when in the normal position to prevent movement of the plunger and the ignition lock from the first position to the second position, the cam surface of the operating member engaging and pivoting the toggle means from the normal position when the operating member is moved in the brake applying direction to permit movement of the plunger and ignition lock from the first position to the second position, and means acting to retain the toggle link in pivoted position when the handle assembly is returned from the brake applying direction to the normal position, the shoulder on the handle assembly engaging the plunger when the handle assembly is in the normal position and the ignition lock is in the second position to prevent movement of the handle assembly in the direction to release the parking brake until the ignition lock is returned to first position.

Claim 6

In a motor vehicle having an ignition lock and a parking brake, a stationary member, a parking brake operating member movably mounted on the stationary member and having a normal retracted position and being movable in one direction from the normal position to apply the parking brake and movable in the other direction from the normal position to release the parking brake, the improvement comprising; a cam surface and a shoulder in laterally and longitudinally spaced relation on the parking brake operating member, toggle means pivotally mounted on the stationary member, spring means biasing the toggle means to a normal position, plunger means operatively connected to the ignition lock and being movable within the stationary member in response to movement of the ignition lock between first and second positions, the toggle means engaging the plunger means when in the normal position to prevent movement of the plunger and the ignition lock from the first position to the second position, the cam surface of the operating member engaging and pivoting the toggle means from the normal position when the operating member is moved in the brake applying direction to permit movement of the plunger and ignition lock from the first position to the second position, and means acting to retain the toggle link in pivoted position when the handle assembly is returned from the brake applying direction to the normal position, the shoulder on the handle assembly engaging the plunger when the handle assembly is in the normal position and the ignition lock is in the second position to prevent movement of the handle assembly in the direction to release the parking brake until the ignition lock is returned to first position.

Claim 7

In a motor vehicle having an ignition lock and a parking brake, the combination comprising; a parking brake operating member mounted in the motor vehicle for forward and rearward movement and having a normal retracted storage position, the operating member being movable in the rearward direction from the storage position to apply the parking brake and movable in the forward direction from the normal storage position to release the parking brake, movable toggle means having a normal position relative the operating member, plunger means operatively connected to the ignition lock and being movable relative the operating member in response to movement of the ignition lock between first and second positions, the plunger means engaging the toggle means when the toggle means is in the normal position to prevent movement of the ignition lock from the first position to the second position, a cam surface on the operating member engaging and moving the toggle means from the normal position and out of engagement with the plunger means when the operating member is moved rearwardly to apply the parking brake to permit movement of the ignition lock from the first position to the second position, and means acting to retain the toggle link out of engagement with the plunger means until the parking brake is released by movemeNt of the operating member forwardly of the normal storage position.

Claim 8

In a motor vehicle having an ignition lock and a parking brake, the combination comprising; a parking brake operating member mounted in the motor vehicle for forward and rearward movement and having a normal retracted storage position, the operating member being movable in the rearward direction from the storage position to apply the parking brake and movable in the forward direction from the normal storage position to release the parking brake, movable toggle means having a normal position relative the operating member, plunger means operatively connected to the ignition lock and being movable relative the operating member in response to movement of the ignition lock between first and second positions, the plunger means engaging the toggle means when the toggle means is in the normal position to prevent movement of the ignition lock from the first position to the second position, a cam surface on the operating member engaging and moving the toggle means from the normal position and out of engagement with the plunger means when the operating member is moved rearwardly to apply the parking brake to permit movement of the ignition lock from the first position to the second position, and means acting to retain the toggle link out of engagement with the plunger means until the parking brake is released by movemeNt of the operating member forwardly of the normal storage position.
