~IELD OF THE INVENTION
The present invention relates to autobody too]s and in particular to a door 1atch alignment tool.
BAC~GRO~ND OF THE INVENTION
Door latch misalignment occurs usually in older or damaged vehicles, and less often in new vehicles where the door simply has not been assembled in proper alignment with the autobody.
The problem can also arise in the course of correcting misalignment of the so-called "character lines"
(surface contours or other body panel shapes, or other exterior details such as paint work, decals or other decorative or functional trim). The first step in realigning the character lines is to loosen the striker from the door post and reposition it either up or down by an amount equal to the amount of misalignment that is observed between corresponding features on the door and the balance of the body. The striker is then secured in its new position, and if the repositioning is in any way substantial then the latch and striker plate will be vertically misaligned as a consequence of adjusting the striker.
In either case the problem manifests as difficulty in operating the door. For the purposes of this patent specification, misalignment shall refer to vertical misallgnment between the latch and striker of the automobile ~ door assembly.

.,, In prior attempts at correcting the door latch misalignment problems, recourse was typically taken to the use of a lever, such as a length of the so called "2x4~' wall studding. With the door of the car at least partially opened, one end of this lever was then placed on the sill of the door opening, with an intermediate portion of the stud being positioned beneath the open door in contacting relation therewith, and the other, free end extending beyond the exterior of the door. The free end was then lifted to force the door back into the desired alignment. A number of difficulties are associated with this practice.
When the lever is lifted against the bottom of the door, the tendency is for the door to move along the stud, with the result that the force applied to the door tends to curl the bottom of the door panel rather than lifting the door ?
upwardly against its hinges. In addition, the lifting force is applied to the lower surfaces of the door, and the load bearing capacity of this portion of the door may not be sufficient to allow the door latch to be realigned without crushing the bottom of the door. This problem is exacerbated in older cars where rust has further weakened the bottom of the door.
Also, the height of the free end of the stud in such an application is only slightly above floor level unless the car is first placed up on jacks. In addition to being inconvenient and time consuming, the use of jacks can be dangerous~ since considerable leverage force is sometimes required to correct the misalignment.

-the other hand, there is the very real risk of back injury to an operator who must bend down to exert leverage from a point so close to floor level.
Accordingly there exists a need for a tool more suitable for correcting common misalignment problems in door latches.
SUM~ARY OF THE INVENTION
In accordance with the present inventlon there is provided an autobody door latch alignment tool including:
strike pin engaging means adapted to engage, and be rotatable about a strike pin mounted on a first door post of an autobody opposite a second door post arranged apart from and generally parallel to the first door post;
door latch engaging means adapted to engage a door latch on a misaligned door that is hung by hinges from the second door post of the autobody, with the door latch engaging means being arranged in mutually spaced apart relation from the strike pin engaging means each at respective points defining a chord along an arc subtended by an angle of the doors rotation about the hinges; and, : lever arm means;
said door latch engaging means and strike pin engaging means being interconnected through means extending transversely to , said chord, and being adapted to be secured in fixed relation :: with said lever arm means, in which arrangement the strike pin ':~ 3 .
~ 3~160~
engaging ~eans is operable to act as a fulcrum when securely engaged in rotatable relation with the strike pin, in response to an application of leverage through the lever arm ~eans fro~
a point remote from both the strike pin engaging means and the door latch engaging means, and the door latch engaging means is operable in conjunction therewith and when engaged with the door latch, to exert a corrective bending moment through the door to the hinges thereof.
Preferably a first portion of the means interconnecting the door latch engaging means and the stri~e pin engaging means e~tends in a first direction from the strike pin engaging means alony the side of the chord opposite the arc, to a second portion extending in a second direction transversely of the chord to a third portion extending in a third direction, on the side of the chord adjacent the arc, to the door latch engaging means.
In one embodiment the tool of the present invention includes a strike pin engaging means which comprises an elongated rectangular bar having an open ended slot arranged in one end thereof. The slot is adapted to receive and engage a portion of the strike pin, which is typically an elongated cylinder, in interfitting relation therewith.
Various slot shapes can be used. For example the slot may be defined between a pair of mutually opposed, parallel sides, or may instead comprise a plurality of nested slQts arranged with the widest slot nearest the slotted end of ; the bar, with successively narrower nested slots arranged in order of decreasing slot width. In accordance with another i .' .
embodiment of the invention the slot has a generally triangular shape with its base opening GUt from the end of the bar, and having sides converging inwardly towards an apex at a point on the bar, spaced apart from opening in the end thereof.
In some applications, the strike pin comprises an elongated cylindrical portion having a first diameter adjacent where it is fixed at one end to an autobody, and a larger diameter portion arranged at the opposite end thereo~. The larger diameter portion may, for example, comprise a disk shaped stop arranged in coaxial relation with the elongated cylindrical portion at the end thereof opposite the end that is fixed to the autobody. In such an arrangement the tool according to one embodiment of the present invention is preferably adapted to engage the elongated cylindrical portion of the strike pin between the two portions of the bar that define the mutually opposed sides of the slot, where the distance between the two portions of the bar is larger than the diameter of the strike pin, but smaller than the diameter of the disc shaped stop.
In a preferred embodiment of the tool of the present invention the end of the bar bearing the slot is lateral~y offset from the door latch engaging means through a compound angle bend in the bar intermediate between the slot and the door latch engaging means. Through the improved clearance from adjacent body parts associated ~ith this arrangement it is possible to locate the tool in use, such that the door need be only slightly ajar, and the corrective bending moment can ~ , ' ' ' ~31~60~
be applied primarily upwArdly to the door, and the mechanical advantage of the avallable leverage can be maximized.
The elongated rectangular bar is preferably also adapted to receive a threaded portion of the door latch engaging means in secured threaded relation with a complimentary tapped bore located in the bar in spaced apart relation from the slot.
The door latch engaging means is preferably adapted to extend outwardly from the bar, and have the same, (typically generally cylindrical), shape as the strike pin.
In this embodiment the door latch engaging means is operable to engage with the door latch in substantially the same way as the strike pin. The tool according to one aspect of the present invention will include a plurality of demountable door latch engaging pins of various sizes, each adapted be secured, one at a time, to the bar and to be used in conjunction with respective ones of a corresponding plurality of variously sized door latches found on different makes and models of automobiles.
