Abstract

Abstract A locking apparatus in a motorcar comprises an operating portion connected between a cylinder lock and an electric ignition switch, the operating portion acting on a locking member which is moved back and forth by rotation of the operation member between a locking position and a released position. An engaging member is advanced by the rotation of the cylinder lock to engage the locking member in the released position and prevent movement thereof to the locking position. A stop member is arranged to project when a key is inserted into the lock to block return movement of the engaging member. When the key is removed, the stop member returns to its original position and allows the engaging member to move and free the locking member for movement to its locking position.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 188 words
A locking apparatus for a motorcar having an ignition switch, said apparatus comprising a cylinder lock with a keyway for insertion of a key, the lock including a rotatable operating portion coupled to the switch such that rotation of the operating portion will produce operation of the switch, a locking member having locking and released positions and coupled with said operating portion to be moved between said locking and released positions when the operatiNg portion is rotated, a displaceable engaging member operatively coupled with said cylinder lock to be moved between a first position in which the engaging member locks said locking member in the released position and a second position in which the locking member is released for movement to the locking position, and stop means for blocking movement of the engaging member to said second position when said key is inserted in the keyway, said stop means comprising a pivotal lever having an initial position partly projecting into said keyway, and a pivotal stop member acted on by said lever for movement into blocking position to prevent movement of the engaging member to said second position.
Claim 2
Dependent Claim 188 words
A locking apparatus for a motorcar having an ignition switch, said apparatus comprising a cylinder lock with a keyway for insertion of a key, the lock including a rotatable operating portion coupled to the switch such that rotation of the operating portion will produce operation of the switch, a locking member having locking and released positions and coupled with said operating portion to be moved between said locking and released positions when the operatiNg portion is rotated, a displaceable engaging member operatively coupled with said cylinder lock to be moved between a first position in which the engaging member locks said locking member in the released position and a second position in which the locking member is released for movement to the locking position, and stop means for blocking movement of the engaging member to said second position when said key is inserted in the keyway, said stop means comprising a pivotal lever having an initial position partly projecting into said keyway, and a pivotal stop member acted on by said lever for movement into blocking position to prevent movement of the engaging member to said second position.
Claim 3
Dependent Claim 37 words
A locking apparatus as claimed in claim 1 wherein said operating portion includes a cam engaging said locking member, the apparatus further comprising spring means acting on said locking member urging the same to said locking position.
Claim 4
Dependent Claim 46 words
A locking apparatus as claimed in claim 2 comprising a projection on said engaging member, said locking member having a recess in which said projection is received when the locking member has been displaced to released position and the engaging member is in said first position.
Claim 5
Dependent Claim 65 words
A locking apparatus as claimed in claim 3 comprising a second spring means, said second spring means acting on said engaging member and urging the same to its second position, and a second cam on said cylinder lock, said second cam being positioned to displace the engaging member to said first position against the action of the second spring means when the lock is turned.
Claim 6
Dependent Claim 25 words
A locking apparatus as claimed in claim 4 wherein said locking member and engaging member are supported for movement at right angles to one another.
Claim 7
Dependent Claim 43 words
A locking apparatus as claimed in claim 1 wherein said engaging member is slidable on said cylinder lock and said stop member is pivotal to a raised position external of the cylinder lock to edgewise abut said engaging member in said blocking position.
Claim 8
Dependent Claim 26 words
A locking apparatus as claimed in claim 6 wherein said pivotal lever is eccentrically connected to said cylinder lock for pivotal movement in a slot therein.
Claim 9
Dependent Claim 38 words
A locking apparatus as claimed in claim 7 comprising a fixed pivot for said stop member external of the cylinder lock, said engaging member resting on said stop member when the engaging member is in said second position.
Claim 10
Dependent Claim 20 words
A locking apparatus as claimed in claim 8 wherein said pivotal lever and stop member are pivotal about perpendicular axes.
