Abstract

An unlocking device (10) for unlocking a vehicle door in the absence of a key. The unlocking device (10) comprises an elongated shank (12) having a first end portion (14) and a second end portion (16). The first end portion (14) of the shank (12) carries a first linkage engaging means (18) and the second end portion (16) of the shank (12) carries a second linkage engaging means (20). The first and further linkage engaging means each defines an arm (22) having an outboard end provided with a U-shaped engaging member (24) for selectively engaging and actuating the door lock linkage (28) of the vehicle door.

Claims

1. An unlocking device for unlocking a vehicle door without a key, said vehicle door including a door lock linkage, the auctuation of which unlocks said vehicle door, said unlocking device comprising:

an elongated shank having a first end portion and a second end portion, said shank being provided with indicia means for marking the desired depth of insertion of said unlocking device into said vehicle door; and

a first linkage engaging means at said first end portion of said shank for selectively engaging and actuating said door lock linkage, said first engaging means including an arm defineing a first length, said arm having an outboard end provided with a U-shaped engaging member for releasably engaging said linkage.

2. The unlocking device of claim 1 wherein said device further comprises a further linkage engaging means at said second end portion of said shank for engaging and actuating said door lock linkage, said further linkage engaging means including an arm defining a second length, said second length being greater than said first length, said arm having an outboard end provided with a U-shaped engaging member for releasably engaging said lock linkage.

3. The unlocking device of claim 2 wherein said U-shaped members of said first and further linkage engaging means comprise a first side portion attached to said arm and a second side portion defining a pointed free-end portion.

4. The unlocking device of claim 1 wherein said U-shaped member defines an outer surface portion provided with a plurality of teeth for selectively engaging said door lock linkage.

5. The unlocking device of claim 1 wherein said U-shaped member defines an outer surface portion provided with a plurality of teeth for selectively engaging said door lock linkage.

6. An unlocking device for unlocking a vehicle door without a key, said vehicle door including a door lock linkage, the actuation of which unlocks said vehicle door, said unlocking device comprising:

an elongated shank having a first end portion and a second end portion, said shank being bendable such that said unlocking device can be selectively reconfigured to facilitate the unlocking of a variety of said vehicle doors, said shank being provided with indicia means for marking the desired depth of insertion of said unlocking device into said vehicle door;

a first linkage engaging means at said first end portion of said shank for selectively engaging and actuating said door lock linkage, said first engaging means including an arm defining a first length, said arm having an outboard end provided with a U-shaped engaging member for releasably engaging said linkage, said U-shaped member including a first side portion attached to said arm and a second side portion defining a pointed free-end portion, said U-shaped member further defining an outer surface portion provided with a plurality of teeth for selectively engaging said door lock linkage; and

a further linkage engaging means at said second end portion of said shank for engaging and actuating said door lock linkage, said further linkage engaging means including a further arm defining a second length, said second length being greater than said first length, said further arm having a outboard end provided with a further U-shaped engaging member for releasably engaging said door lock linkage, said further U-shaped member including a first side portion attached to said further arm and a second side portion defining a pointed free-end portion, said further U-shaped member further defining a outer surface provided with a plurality of teeth for selectively engaging said door lock linkage.

7. The unlocking device of claim 6 wherein said free-end portion of said second side portion of each said U-shaped member is outwardly flared to facilitate the engaging of said door lock linkage.

8. The unlocking device of claim 6 wherein said first and further linkage engaging means define first and further narrowed flank portions.

9. An unlocking device for unlocking a vehicle door without a key, said vehicle door including a door lock linkage, the actuation of which unlocks said vehicle door, said unlocking device comprising:

an elongated shank having a first end portion and a second end portion; and

a first linkage engaging means at said first end portion of said shank for selectively engaging and actuating said door lock linkage, said first engaging means including an arm defining a first length, said arm having an outboard end provided with a U-shaped engaging member for releasably engaging said linkage, said U-shaped member including a first side portion attached to said arm and a second side portion defining a pointed free-end portion, and including a further portion connecting and extending between said first side portion and said second side portion.

10. The unlocking device of claim 9 wherein said further portion of said U-shaped member is provided with a flattened outer surface for providing a further engaging surface for engaging said linkage.

11. An unlocking device for unlocking a vehicle door without a key, said vehicle door including a door lock linkage, the actuation of which unlocks said vehicle door, said unlocking device comprising:

an elongated shank having a first end portion and a second end portion, said shank being bendable such that said unlocking device can be selectively reconfigured to facilitate the unlocking of a variety of said vehicle doors;

a first linkage engaging means at said first end portion of said shank for selectively engaging and actuating said door lock linkage, said first engaging means including an arm defining a first length, said arm having an outboard end provided with a U-shaped engaging member for releasably engaging said linkage; and

a bend chart illustrating at least one preferred angular configuration into which said shank can be bent to facilitate the engaging of said door lock linkage, whereby said shank is positioned to overlay said bend chart and bent to correspond to said preferred angular configuration.
