Abstract
Abstract An anti-theft lock for association with a vehicle part (e.g., trunk, or hood) or system (e.g., fuel line, or hydraulic brake) has a passage which permits normal operation except when closed after manual operation of a push-button lock. To prevent long term bleed down, advantageous means are provided so that it is the thief himself who sets the brakes, closes off the gas line, or whatever.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
163 words
In an anti-theft locking device for automotive applications, a lock of the push-to-lock, key-turn-to-unlock type, a pair of spring material hook arms having portions secured to be stationary with stationary portions of the lock and having other portions forming hooks adapted to be sprung apart, a rod or tube means connected to linearly move and circumferentially turn with a relatively movable portion of the lock, a wedge means associated for movement with the rod or tube and configured and arranged so that the push-to-lock function of the lock (e.g., key-hole at 12 o''clock) causes the wedge to (1) force the hook arms apart, (2) thereafter be restrained by the hook arms as they snap inwardly with such restraint of the wedge continuing until such time as there is a key-to-unlock function (e.g., key-hole at 3 o''clock, just before return to 12 o''clock for key removal), and a spring means for forcing the wedge to clear itself from the hooks for the key-to-unlock function.

Claim 3
Dependent Claim
106 words
The combination of claim 1 further characterized by, a customary o.e.m. fluid pressure system for the vehicle, an added piston-cylinder combination the cylinder of which is relatively stationary and has an inlet port and an outlet port and fluid pressure passage means therebetween while the piston of the combination is associated for movement with the rod and wedge for selectively closing and opening said passage means in the cylinder, and a check means which prevents total but permits some communication between inlet and outlet for a key lock locked time, whereby to prevent long term bleed-down while preventing substantial movement of the vehicle in city traffic.
