Abstract

A remotely controlled hood lock release blocker assembly for preventing the release of a vehicle hood latch which includes a cable coupled to the hood release. The cable is secured to a platform journaled for rotation along the full length of a limited arc required to effect release of the hood latch and one of an electromagnetically controlled lever and mechanical dead bolt is provided for interfering with the rotation of the platform the full length of the limited arc preventing completion thereof whereby to prevent release of the hood. A control device in the form of a key operated energizing device for the electromagnet or a key operated control for withdrawing the lever and dead bolt respectively, is provided remote from the blocker assembly for changing the condition of the lever and dead bolt from interferent to non-interferent condition respectively.

Claims

1. A remotely operable blocker assembly for a vehicle hood lock release mechanism, said mechanism including a pivotable latch and a keeper, said pivotable latch retained by the keeper and a cable coupled to the latch and manipulatable to release the latch from the keeper permitting release of the hood, said blocker assembly comprising:

a base plate mounted along a length of the cable, guide means for leading a length of the cable through said assembly, platform means journaled on said base plate for rotation through a limited arc, said platform means secured to said length of said cable so that the full extent of said arc is required to release the latch, an upstanding stop on said platform means and rotatable therewith, means projectable across the path of said upstanding stop to interfere with passage thereof through the full extent of said limited arc and remote means for operating said projectable means between the interferent and noninterferent condition.

2. The blocker assembly as claimed in claim 1 including clamp means secured to said platform means, said cable provided with a sheath, said length of cable having a portion bared of said sheath and said bared portion being clamped to said platform means, whereby manipulation of said cable effects rotation of said platform means along said limited arc.

3. The blocker assembly as claimed in claim 2 in which said clamp means comprise a plate and fastening means tightly securing said plate to said platform means at a location spaced from said stop, said plate having a surface facing said platform means and a transverse groove formed herein, said bared cable portion being seated within said groove.

4. The blocker assembly as claimed in claim 3 in which said groove has at least one coined portion at least at one of the exit and entrance thereto to define a smooth tapered entrance and/or exit respectively for said bared portion and reduce frictional wear thereon.

5. The blocker assembly as claimed in claim 1 including means operable manually to release said projectable means from said interferent condition.

6. The blocker assembly as claimed in claim 1 wherein said projectable means comprise an elongate member having a pair of opposite end portions and a mid-portion, a housing having opposite walls and slot means in said walls suitable for receiving said elongate member mounted therethrough, an electromagnet seated within said housing below said mid-portion, resiliient means secured to said electromagnet and said mid-portion spacing same, electrical circuit means coupled to said electromagnet for energizing same, one end of said elongate member extending across the path of said stop, said one end normally being in interferent condition relative said path of said stop and in non-interferent condition when said electromagnet is energized.

7. The blocker assembly as claimed in claim 5 in which said manually operable means comprise a flexible length secured to the opposite end portion of said elongate member and extending toward an underside of the vehicle.

8. The blocker assembly as claimed in claim 1 in which said projectable means includes a housing having opposite end walls and located next adjacent said path, aperture means in said walls, a dead bolt assembly seated within said housing, said dead bolt assembly including a pin member of size and configuration suitable for passage through at least said aperture means formed in the housing wall next adjacent said path and in interferent relation thereto.

9. The blocker assembly as claimed in claim 1 in which said platform means comprise a planar plate member, means securing said plate member to said base plate journaled for rotation along a limited arc, a second stop on said plate member adjacent said guide means.

10. The blocker assembly as claimed in claim 9 including spring means secured to said guide means and said second stop to return said plate member to its initiate condition when said rotation thereof has been completed.

11. A remotely operated hood lock release blocker assembly for a vehicle having a hood latch and a cable secured to the hood latch, the cable being manipulatable to release the hood latch, said assembly comprising:

a base plate mounted along a length of said cable, a rotatable platform connected to said cable and journaled on said base plate for rotation between a first condition and a second condition enabling release of the hood lock, blocker means intermediate said first and second conditions for preventing said platform from reaching the second condition, said blocker means including a blocking member disposed between a first interferent position intermediate the path of said platform preventing said platform from reaching the second condition and a second position permitting said platform to reach said second condition, and means operable upon said blocking member for placing same in one of said first or second positions.

12. The blocker assembly as claimed in claim 11 in which said blocking member comprises an electromagnetically controlled lever.

13. The blocker assembly as claimed in claim 11 in which said blocking member comprises a mechanically operated dead bolt.

14. The blocker assembly as claimed in claim 11 in which said cable is provided with a sheath and includes a portion bared of said sheath, said bared portion being flexed during limited rotation ofs aid platform, means for clamping said bared portion to said platform, said platform having an upstanding stop on a portion thereof, said blocking means intercepting said stop prior to the platform reaching its release condition.

15. The blocker assembly as claimed in claim 11 including means biasing said platform automatically to return same to its first condition when the cable is released.

16. The blocker assembly as claimed in claim 11 including means manually operable to release said blocking member from its interferent position.

17. The blocker assembly as claimed in claim 11 in which said blocking means comprise a lever having a pair of opposite end portions and a mid-portion, an electromagnet, said lever disposed overlying said mid-portion overlying said electromagnet, one end of said lever extending in interferent relationship with rotation of said platform when said electromagnet is de-energized and in non-interferent relationship when said electromagnet is energized, and electrical circuit means coupled to said electromagnet for energizing and de-energizing same.

18. The blocker assembly as claimed in claim 17 including means coupled to the other end of said lever for manually changing the condition of said lever from interferent condition to non-interferent condition.

19. The blocker assembly as claimed in claim 11 in which said blocking means comprise a dead bolt assembly including a bolt member capable of being thrust across said path of an upstanding stop on said platform in said first condition, and means for operating said dead bolt including remote key operated means.
