Abstract
A device which protects against the unauthorized taking of an automobile by rigidly joining the shaft of a gearshift lever to the grip portion of a hand brake. The device has application to autos equipped with a console mounted gearshift and parking brake and includes a plunger activated lock assembly having easily releaseable features.
Claims11
An anti-theft device for locking the shaft of an auto gearshift lever to a parking brake which comprises:
- (1) an elongated hollow body having a longitudinal chamber which includes a concavity for receiving the grip portion of a hand brake;
- (2) a solid flat extension member of rectangular configuration hingedly secured within said chamber, said member having an upper surface, a lower surface, opposing sidewalls and opposing endwalls and including:
- (a) a plurality of apertures which are serially arranged along a line to extend into said member;
- (b) a longitudinal bore extending for about half the length of said member and having an axis parallel to and spaced from said aperture line and terminating in a bore opening which is adapted to receive the circular rod of the member described in (3) infra;
- (c) a set screw and a threaded bore which is adapted to receive the set screw in perpendicular communication with said longitudinal bore;
- (3) a generally F-shaped retaining member consisting essentially of a flat segment having an arcuate cutout to which has been joined a circular rod which is slidingly engaged within said longitudinal bore and which may be held in place by threadedly engaging said set screw within said threaded bore;
- (4) a hollow elongated sleeve which slidingly receives said extension member, said sleeve having an upper surface, a lower surface and sidewall surfaces, including on said upper surface a lock equipped with a depressable plunger for engaging an aperture in said extension member and further including on said upper and lower surfaces at their terminal ends, arcuately shaped cutouts which lie in registry to receive the shaft of said gear shift lever.

An anti-theft device for locking the shaft of an automobile gearshift lever to a parking brake comprising:
- an elongated body having a longitudinally extending chamber extending inwardly from one end thereof for receiving the grip portion of a parking brake,
- a flat extension member hingedly secured at the other end of said body to extend in a longitudinal direction therefrom, said extension member having a flat upper surface and a flat lower surface,
- a plurality of apertures formed in a portion of said extension member, said apertues being arranged in a spaced apart serial relationship along the length of said extension member,
- a longitudinal bore in said extension member extending longitudinally inwardly from one end thereof, spaced from and along side of said apertures and providing a bore opening in said one end of said extension member,
- a retaining member including a flat segment portion defining a cutout for surrounding a portion of the shaft of a gearshift lever, said retaining member including a rod portion slidingly received in said longitudinal bore in said extension member and extending therefrom in a longitudinal direction to join with said segment portion,
- means for securing said retaining member in a set position relative to said extension member,
- an elongated sleeve having a longitudinally extending internal chamber for slidably receiving said segment portion of said retaining member and the portion of said extension member having said apertures formed therein, said sleeve having an upper wall located adjacent said upper surface of said extension member and a lower wall located adjacent said lower surface of said extension member, said sleeve having wall means cooperable with wall means of said retaining member and said extension member so that said sleeve is slidable longitudinally relative to said retaining member and said extension member, and
- a lock means mounted on said upper wall and including a depressible plunger for engaging an aperture in said extension member,
- said sleeve having a cutout at an extended end thereof adapted to surround a portion of the gearshift lever shaft, said cutout in said retaining member and said cutout in said sleeve member cooperating to form a locking enclosure extending completely around the gearshift lever shaft when said device is in its locking position.
