## Background
FIELD OF THE INVENTION
The present invention relates to autobody tools, in particular, to a vehicle door aligning and leveling tool.
BACKGROUND OF THE INVENTION
It is a common problem in automotive vehicles that the hinged door of an automotive vehicle is misaligned during the initial manufacture. This misalignment causes the door to not properly close or be misaligned when closed. Misalignment may cause air gaps in the seal of a closed vehicle door leading to noise heard by the driver, among other problems.
Overcoming such a misalignment is often completed by a mechanic or other automotive worker by applying a force to the lower portion of the vehicle door to improve its alignment. This may be accomplished generally by the crude method of grabbing a vehicle door with the hands and pushing or pulling on the vehicle door to improve alignment of the vehicle door. The method of grabbing a vehicle door with the hands often results in injury to assembly plant workers or other automotive workers. This method can often damage the vehicle door by either damaging the paint or leaving an indentation in the bottom of the vehicle door.
It is one object of the present invention to provide an improved alignment tool which can be used to apply force to the vehicle door without the danger of damaging the surface of the vehicle door. It is another object of the invention to provide an apparatus which avoids scratching or damaging of any paint or any deformation of any vehicle door structure.
Yet another method of alignment involves kneeling on the ground and pulling or pushing the bottom of the vehicle door with hands to level and align the vehicle door. Again, this method often results in injury to assembly plant workers or other automotive workers.
Another object of the present invention is to minimize risk of injury to assembly plant workers or other automotive workers when aligning a vehicle door by means of using their hands or knees when aligning the vehicle door.
Vehicle door designs often vary greatly in different models and makes of vehicles. It is an object of the invention to provide an apparatus which is simple and universal to all automotive vehicle doors and structures. It is another object of the invention to provide an apparatus which will cooperate with a wide variety of automobile and vehicle structures.
Accordingly there exists a need for a tool more suitable for correcting common misalignment and level problems in vehicle doors.
SUMMARY OF THE INVENTION
The present invention is for a tool for use in aligning and leveling a vehicle door. A vehicle door typically has a door lock assembly which receives a lock pin on the door frame to secure the vehicle door in a closed position. Accordingly, the corresponding vehicle door typically includes a recess for accepting the lock pin on the door frame. The tool of the preferred embodiment includes an elongated member having a support member extending downwardly from the elongated member towards a vehicle door. The tool further includes a head member attached to the elongated member adapted to engage a vehicle door lock recess of a locking means of a vehicle door. The door leveler further includes a support plate attached to the support member adapted to rest against a vehicle door.
In another embodiment of the present invention, the elongated member may be configured with an ergonomic design to reduce burden on users of the door leveler. An ergonomic configuration of the elongated member may increase maneuverability of a vehicle door during the leveling process. The ergonomic configuration of the elongated member may include a series of bends in the elongated member. This ergonomic configuration lowers the user grip area from the head member allowing a user to gain more control and improve user lift ability. The ergonomic bends allow the grip area of the device to be substantially parallel while substantially lower than the working area of the vehicle door. Lowering the grip area allows a user of the door leveler to exert more force on the door leveler while minimizing risk of injury.
The vehicle door leveler is intended to assist in the lifting, pushing and pulling processes when aligning and leveling a vehicle door. The head member engages the vehicle door lock recess while the support plate simultaneously braces against the vehicle door. The user of the vehicle door leveler then uses the elongated member to pull or push the vehicle door in turn causing the vehicle door to move in accordance with proper alignment of the vehicle door.
A support member may extend downwardly from the elongated member to the vehicle door at various different points on the elongated member. The support member acts as a brace to further simplify use of the vehicle door leveler and to minimize burden on the user of the vehicle door leveler.
The support plate includes a front surface and a rear surface. The rear surface of the support plate is secured to the support member. The front surface of the support plate has a resilient surface adapted to prevent scratching of the paint or other damage to the vehicle door.
The foregoing and other objects, embodiments, features and advantages of the invention will become readily apparent from the following detailed description which proceeds with references to the accompany drawings.

DETAILED DESCRIPTION OF THE INVENTION
The present invention is a tool for use in aligning and leveling a vehicle door. A vehicle door typically includes a door lock assembly which receives a lock pin on the door frame to secure the vehicle door in a closed position, as shown in FIG. 1. The corresponding vehicle door typically includes a recess for accepting the lock pin on the door frame. FIG. 1 depicts an idealized motor vehicle 10 having a vehicle body 18 on which vehicle door 12 is hingedly mounted. Vehicle autobody workers are often required to reposition the vehicle door 12 with respect to vehicle body 18 in order to properly align and level the vehicle door 12 with respect to vehicle body 18. Movement is accomplished when the user of the vehicle door leveler 20 pushes and pulls on the elongated member 24 of the vehicle of the vehicle door leveler 20 (as shown by movement arrows 14, 16). Said pushing of the vehicle door 12 facilitates the alignment process allowing workers to properly align the vehicle door 12.
The vehicle door leveler 20 in the embodiment here specifically disclosed is primarily formed of an elongated member 24, here shown in the form of a tubular shaft. Elongated member 24 may also be, but not limited to, in the form of a rectangular elongated member or other variations of an elongated member not otherwise depicted.
Elongated member 24 may optionally include a series of bends. Elongated member 24 bends are depicted at 52 and 54. Elongated member 24 may include between zero and four bends, not otherwise depicted in the drawings. The bends 52 and 54 are intended to improve usability to a user of the door leveler. This ergonomic configuration lowers the user grip area from the head member allowing a user to gain more control and improve user lift ability. The ergonomic bends allow the grip area of the device to be substantially parallel while substantially lower than the working area of the vehicle door. Lowering the grip area allows a user of the door leveler to exert more force on the door leveler while minimizing risk of injury.
Elongated member 24 may include more or less than the two bends 52 and 54 depicted in the drawings. Elongated member 24 may have a medial portion 38 between a grip portion 36 and a distal portion 40. Bends 52 and 54 may be provided at the joints of the medial portion 38, grip portion 36 and the distal portion 40. Bends 52 and 54 are discussed in further detail in this description.
Elongated member 24 includes a head member 22 adapted to engage a recess 30 on a side panel 32 of a vehicle door 12. Head member 22, as depicted in FIG. 2, may be U-shaped. Head member 22 could form several other different shapes including, but not limited to, a rectangular shaped head member, a circular shaped head member, a tubular shaped head member, etc.
Elongated member 24 further includes a support member 28 which extends downwardly from the elongated member 24 to the side panel 32 of the vehicle door 12. In one embodiment, support member 28 is fixedly secured to elongated member 24 at the joint 34. In another embodiment, support member 28 is rotatably mounted to elongated member 24 at the joint 34. The support member 28 is designed to minimize burden on the user of the vehicle door leveler 20. The support member 28 acts as a brace to further simplify use of the vehicle door leveler 20. The support member also provides an ergonomic benefit to the user of the vehicle door leveler 20 by reducing the force needed to raise and lower the vehicle door.
The vehicle door leveler is depicted in a series of embodiments shown in FIGS. 3-9. These various embodiments have different configurations of bends and support member placement.

Generally, elongated member 24 is formed of a medial portion 38 between a grip portion 36 and a distal portion 40. Grip portion 36, medial portion 38 and distal portion 40 are formed of a single contiguous piece. Bends 52 and 54 may be provided at the joints of the medial portion 38, grip portion 36 and the distal portion 40. Bend 54 is measured by an angle ‘x’ as shown in FIGS. 3, 4, 5, 8 and 9 on the topside of the elongated member 24. Bend 52 is measured by an angle ‘y’ as shown in FIGS. 3, 4, 5, 8 and 9 on the underside of elongated member 24. Both angles ‘x’ and ‘y’ have a measure between 90°-270°. Bend 52 may also be measured by angle ‘z’ measured on the topside of the elongated member 24. Angle ‘z’ may have a measure between 60°-310°. Angles ‘x’, ‘y’ and ‘z’ are independent of each other and may have different measurements.
The first, second, third, fourth, seventh and eighth embodiments, as depicted in FIGS. 3, 4, 5, 8 and 9, respectively, include a series of two bends located at 52 and 54. In the first, second, third, fourth, seventh and eighth, angles ‘x’, ‘y’ and ‘z’ may have a measure between 90°-270°.
As depicted in FIGS. 6 and 7, fifth and sixth embodiments, respectively, angles ‘x’, ‘y’ and ‘z’ may have a measure of 180°. When angles ‘x’, ‘y’ and ‘z’ have a measure of 180°, the elongated member 24 is perfectly straight.
The vehicle door leveler is depicted in a series of embodiments shown in FIGS. 4-10. These various embodiments have different configurations of support member 28 placement. Support member 28 placement on the elongated member 24 may vary. Placement of the support member 28 on the elongated member 24 may either be closer to the head member 22, centered on the elongated member 24, or closer to the grip portion 36. The support member 28 may also extend downwardly toward the vehicle door from the grip portion 36, the medial portion 38 or the distal portion 40 of the elongated member 24. For example, FIG. 3 (first embodiment), the support member 28 extends downwardly from the grip portion 36 of the elongated member 24. In FIG. 4 (second embodiment), the support member 28 extends downwardly from the grip portion 36 of the elongated member 24. In FIG. 5 (third embodiment), the support member 28 extends downwardly from the medial portion 38. Various placements of the support member 28 may improve user maneuverability.
Support member 28 includes a support plate 26. In the preferred embodiment, support plate 26 is fixedly secured to the support member 28. Support plate 26 may also be rotatably mounted about support member 28 or otherwise movable on support member 28. Support plate 26 includes a rear surface 48. Support plate 26 connects to support member 28 on a location on the rear surface 48 of the support plate 26. Support plate 26 also includes a front surface 46. Front surface 46 of support plate 26 is covered, at least partially, with a resilient surface 50. Resilient surface 50 may include, but is not limited to, a cloth material, flexible rubber or other polymer material, nylon, foam, cotton substrate . . . etc. Resilient surface 50 is designed to prevent scratching, denting, or other damage to the vehicle door 12.
As demonstrated by the use in FIG. 2, head member 22 is adapted to engage a recess 30 of a side panel 32 of a vehicle door 12. The operator of the vehicle door leveler 20 may either lift or push down on the vehicle door leveler 20 to attain the proper level and alignment of the vehicle door 12. Support member 28 and support plate 26 are adapted to engage the side panel 32 of the vehicle door 12. The support member 28 acts as a brace to further simplify use of the vehicle door leveler 20. The support member also provides an ergonomic benefit to the user of the vehicle door leveler 20 by reducing the force needed to raise and lower the vehicle door.
FIG. 7 depicts yet another embodiment wherein support member 28 includes a support member bend 56. Support member bend 56 may improve usability for the user of the vehicle door leveler. The bend may reduce the ergonomic burden on the user of the vehicle door leveler.
