Abstract
Abstract A vehicle shift lever locking mechanism for retrofitting to motor vehicles includes in one form a universal adapter to enable the locking mechanism to be fitted to shift levers of a wide variety of motor vehicles. The universal adapter is received at least in part within a handle and a locking assembly is also received in part within the universal adapter and the handle so as to mechanically interlock the components in assembled relationship. The handle is designed to overlie the fastening arrangement which secures the universal adapter to the shift lever and thus prevents unauthorized removal of the locking mechanism. Embodiments of the locking mechanism are suited for either cable or rod actuated shift mechanisms. In another form the locking mechanism is formed for attachment to a steering column shift mechanism and includes a lock assembly movable within a housing mounted on the steering column to a position in which the lock assembly prevents pivotal releasing movement of the shift lever.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
148 words
In a motor vehicle having a shift mechanism including a releasable latch mechanism for retaining the shift lever in a preselected position, an improved locking mechanism for preventing movement of said shift lever from said preselected position, said lock system being characterized by: a handle member having a bore provided therein; a universal adapter member disposed within said bore and including an opening in one end thereof adapted to telescopically receive an end portion of said shift lever; means for securing said universal adapter to said shift lever; and selectively actuable locking means disposed within said handle member, said locking means, said locking means including a portion extending through an opening provided in said universal adapter adjacent the other end thereof so as to be operable to mechanically interlock said universal adapter and said handle member in assembled relationship and to selectively prevent release of said latching mechanism.
Claim 2
Dependent Claim
148 words
In a motor vehicle having a shift mechanism including a releasable latch mechanism for retaining the shift lever in a preselected position, an improved locking mechanism for preventing movement of said shift lever from said preselected position, said lock system being characterized by: a handle member having a bore provided therein; a universal adapter member disposed within said bore and including an opening in one end thereof adapted to telescopically receive an end portion of said shift lever; means for securing said universal adapter to said shift lever; and selectively actuable locking means disposed within said handle member, said locking means, said locking means including a portion extending through an opening provided in said universal adapter adjacent the other end thereof so as to be operable to mechanically interlock said universal adapter and said handle member in assembled relationship and to selectively prevent release of said latching mechanism.
Claim 3
Dependent Claim
42 words
A lock system as set forth in claim 1 wherein said opening in said universal adapter is sized in accordance with an outside diameter of said shift lever whereby said lock system may be fitted to a wide variety of motor vehicles.
Claim 4
Dependent Claim
44 words
A lock system as set forth in claim 1 wherein said locking means includes a locking cylinder movably disposed within said bore and having a radially outwardly projecting tab portion, said tab portion being operable to mechanically interlock said handle and said universal adapter.
Claim 5
Dependent Claim
71 words
A lock system as set forth in claim 3 wherein said shift lever is hollow and said shift mechanism further includes a rod member projecting upwardly through said hollow shift lever, said rod member being upwardly spring biased and forming a part of said latching mechanism, said lock system further comprising means for moving said rod inwardly with respect to said shift lever in response to movement of said locking cylinder.
Claim 6
Dependent Claim
66 words
A lock system as set forth in claim 4 wherein said means for moving said rod comprise a plunger member disposed between said rod and said cylinder, said rod acting against said plunger whereby said locking cylinder is normally biased into a position projecting outwardly from said handle member, movement of said locking cylinder into said handle member being operable to effect movement of said rod.
Claim 7
Dependent Claim
17 words
A lock system as set forth in claim 4 wherein said plunger is secured to said rod.
Claim 8
Dependent Claim
49 words
A lock system as set forth in claim 5 further comprising a tab portion on said locking cylinder, said tab portion being radially movable with respect to said cylinder and selectively receivable within a recess provided in said handle member to prevent movement of said cylinder and said plunger.
