Abstract
Abstract A lock mechanism preferably for use in a motor vehicle is disclosed and includes safety features to prevent an operator from leaving the keys in the vehicle when it is left unattended. One important purpose of the present invention is to provide means for preventing the operator from starting the vehicle after a proper key has unlocked the lock mechanism, without first withdrawing the key from the lock mechanism. After the key has been extracted, the lock mechanism can then be rotated to a vehicle start position, and the key need not be inserted again to thereafter rotate the lock mechanism to its locked position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
155 words
A lock comprising; a mounting housing, a key-receiving means rotatable within said housing including a key-receiving opening and means for locking the key-receiving means against rotation, said locking means operable by the insertion of a proper key in the key-receiving opening to free the key-receiving means for rotation, and means coupled between the mounting housing and the keyreceiving means for preventing rotation of said key-receiving means after said key-receiving means has been freed for rotation and before said key-receiving means has reached a vehicle start position, said mounting housing having means defining a slot extending lengthwise of said housing, said locking means including a plurality of pins that are alignable when the proper key is inserted in the key-receiving opening to free the key-receiving means for rotation, and that are free to extend into sAid slot when the means for preventing rotation has stopped further rotation of the key thereby enabling withdrawal of the key.
Claim 2
Dependent Claim
155 words
A lock comprising; a mounting housing, a key-receiving means rotatable within said housing including a key-receiving opening and means for locking the key-receiving means against rotation, said locking means operable by the insertion of a proper key in the key-receiving opening to free the key-receiving means for rotation, and means coupled between the mounting housing and the keyreceiving means for preventing rotation of said key-receiving means after said key-receiving means has been freed for rotation and before said key-receiving means has reached a vehicle start position, said mounting housing having means defining a slot extending lengthwise of said housing, said locking means including a plurality of pins that are alignable when the proper key is inserted in the key-receiving opening to free the key-receiving means for rotation, and that are free to extend into sAid slot when the means for preventing rotation has stopped further rotation of the key thereby enabling withdrawal of the key.
Claim 3
Dependent Claim
57 words
A lock as set forth in claim 1 wherein said means for preventing rotation includes a ball bearing, said key-receiving means having a passage therein for accommodating said ball bearing, said mounting housing having a groove therein for accommodating said ball bearing when said lock is in a locked position with said key inserted into said lock.
Claim 4
Dependent Claim
49 words
A lock as set forth in claim 2 wherein said groove in said mounting housing terminates in a shoulder against which said ball bearing may move to prevent further rotation of said key-receiving means relative to said mounting housing as long as said key is in said key-receiving means.
Claim 5
Dependent Claim
40 words
A lock as set forth in claim 1 wherein said means for preventing rotation is operative after said key has been withdrawn from said key receiving means to allow said key-receiving means to be rotated to the vehicle start position.
Claim 6
Dependent Claim
170 words
A lock comprising; a mounting housing, a key-receiving means rotatable within said housing including a key-receiving opening and means for locking the key-receiving means against rotation, said locking means operable by the insertion of a proper key in the key-receiving opening to free the key-receiving means for rotation, and means coupled between the mounting housing and the key-receiving means for preventing rotation of said key-receiving means after said key-receiving means has been freed for rotation and before said key-receiving means has reached a vehicle start position, said locking means including a locking member and a plurality of actuable members each having a surface engageable with the key when the key is inserted in the key-receiving means and a second surface having a notch therein for accommodating the locking member, all said notches being aligned when the proper key is inserted to enable freeing of the key-receiving means for rotation, at least one of said actuable members having a notch that has a length greater than the length of other notches.
Claim 7
Dependent Claim
170 words
A lock comprising; a mounting housing, a key-receiving means rotatable within said housing including a key-receiving opening and means for locking the key-receiving means against rotation, said locking means operable by the insertion of a proper key in the key-receiving opening to free the key-receiving means for rotation, and means coupled between the mounting housing and the key-receiving means for preventing rotation of said key-receiving means after said key-receiving means has been freed for rotation and before said key-receiving means has reached a vehicle start position, said locking means including a locking member and a plurality of actuable members each having a surface engageable with the key when the key is inserted in the key-receiving means and a second surface having a notch therein for accommodating the locking member, all said notches being aligned when the proper key is inserted to enable freeing of the key-receiving means for rotation, at least one of said actuable members having a notch that has a length greater than the length of other notches.
