发明名称 Anti-theft device for automobile doors
摘要 A device for securing the latch buttons of automobile door locks against tampering from the outside of the vehicle comprises a sleeve engaged upon the shaft of the latch button with a depression, or counterbore, in the upper surface of the sleeve for receiving the lower face of the button proper in the closed - pushed-down - position. The sleeve is preferably made of a plastic or metal material and may be provided with a roughened or knurled outer surface to ease lifting the latch button into the open position. A locking tab may depend from the sleeve and be engaged in a separate lock attached to the inner face of the automobile door.
