Automobile car door lock opener and closer

Claim 2

For use with the locking mechanism for automobile doors including a button and dependent shank slidable up and down in the door structure and projecting above the window sill, a car door lock opener operable from the driver''s seat for lifting the button and shank to unlock the door locking mechanism comprising: a. a weighted slide member having substantially unobstructed outer surface walls, b. an elongated handle attached to one side of said slide member, c. bifurcated means on a forward extension of said weighted slide member at a right angle to said handle, said bifurcated means comprising prongs extending substantially in a plane along the axis of the handle and being spaced relative to one another so that the slot defined between the prongs is of a width to surround the shank of the locking mechanism, d. said forward extension on the slide member having a lower surface cut away and lying in a plane spaced above the plane of the lower edge of the slide member, and e. a fulcrum at the meeting lower edge of the slide member and its forward extension so that the slide member is rockable up and down for initial convenient entry of the forward extension beneath the button and a final rocking of said extension upwardly to pry the button and entrained shank up to release the lock.

Claim 3

A device as claimed in claim 1 further comprising g. a hammer head on the handle offset angularly from the claw by which through the raising and lowering movement of the free end of the handle a blow or blows may be delivered to the button for driving same down to cause locking of the door.

Claim 4

For use with the locking mechanism for automobile doors including a button and dependent shank slidable up and down in the door structure and projecting above the window sill, an article of manufacture comprising, a device operable from the driver''s seat for lifting the button and shank to unlock the mechanism comprising a. a slide member adapted to slide along the window sill, b. a handle attached to the member and reaching at least to the extended hand of the operator whereby the operator may conveniently cause the slide member to slide along the sill and engage the button, c. means on the member for lifting the button and entrained shank incident to the sliding movement of the member along the window sill toward the button whereby to release the locking mechanism comprising d. a forward extension on the slide member adapted to enter beneath the button and having an upper edge inclining from its free end upwardly toward the slide member for automatically effecting raising movement of the button as the slide moves along the window sill toward and beneath said button, said member having, e. an abruptly raised surface adjacent to and inwardly of the upper edge of the forward extension for imparting a final abrupt lifting force to the button and the shank of great magnitude to overcome any friction between the shank and the door structure to insure the dislodgment of the button and shank during the final stage of the sliding movement of the slide member toward and beneath the button, said member having, f. a lower edge inclining downwardly toward the slide member and said member also having, g. a gently curving convex surface adjacent to and inwardly of the lower edge of the forward extension to provide a lower fulcrum on which the slide member may be rocked on the window sill to elevate the forward extension in the act of prying the button and shank to an upper-unlocked position, the extension further having, h. a slot opening through the outer end of the extension with prongs at the sides of the slot adapted to extend beneath opposite sides of the button while the shank occupies the slot, said prongs being substantially parallel to one another so that the slot is of uniform width throughout its entire length, and i. the ends of said prongs having rounded off surfaces.

Claim 5

For use with the locking mechanism for automobile doors including a button and dependent shank slidable up and down in the door structure and projecting above the window sill, an article of manufacture comprising, a device operable from the driver''s seat for lifting the button and shank to unlock the mechanism comprising a. a slide member adapted to slide along the window sill, b. a handle attached to the member and reaching at least to the extended hand of the operator whereby the operator may conveniently cause the slide member to slide along the sill and engage the button, c. means on the member for lifting the button and entrained shank incident to the sliding movement of the member along the window sill toward the button whereby to release the locking mechanism comprising d. a forward extension on the slide member adapted to enter beneath the button and having an upper edge inclining from its free end upwardly toward the slide member for automatically effecting raising movement of the button as the slide moves along the window sill toward and beneath said button, said member having, e. an abruptly raised surface adjacent to and inwardly of the upper edge of the forward extension for imparting a final abrupt lifting force to the button and the shank of great magnitude to overcome any friction between the shank and the door structure to insure the dislodgment of the button and shank during the final stage of the sliding movement of the slide member toward and beneath the button, said member having, f. a lower edge inclining downwardly toward the slide member and said member also having, g. a gently curving convex surface adjacent to and inwardly of the lower edge of the forward extension to provide a lower fulcrum on which the slide member may be rocked on the window sill to elevate the forward extension in the act of prying the button and shank to an upper-unlocked position, the extension further having, h. a slot opening through the outer end of the extension with prongs at the sides of the slot adapted to extend beneath opposite sides of the button while the shank occupies the slot, said prongs being substantially parallel to one another so that the slot is of uniform width throughout its entire length, and i. the ends of said prongs having rounded off surfaces.

Claim 6

A device as claimed in claim 3 further comprising j. means on the slide member for driving the button and shank downwardly to cause locking of the mechanism, said slide member and said driving means being of substantial weight so that their mass times velocity (MV) equation will be proportional to the work it is calculated to perform in the hand of the operator.
