Description

RELATED APPLICATIONS

This application claims benefit of priority of Provisional Application Ser. No. 60/765,721, filed Feb. 7, 2006, hereby incorporated by reference in its entirety.

BACKGROUND OF INVENTION

a. Field of Invention
The invention relates generally to an apparatus and method for use in an automotive manufacturing and repair process, and, more particularly, to an apparatus for mounting and handling of automotive doors and other such components.
b. Description of Related Art
During the manufacture of automobiles, doors and other such components are generally installed onto an automobile in an assembly line process. After initial alignment and installation of an automobile door, ideally the door would not have to be removed. However, it is often necessary for doors and similar components to be periodically removed at different stages of the manufacturing process for installation of sub-components and/or application of treatments to the door itself. In a similar manner, repair of a door and/or repair of a door subcomponent often requires the removal of the door.
Due to the significant amount of weight and dimensions of a typical automobile door, it is often difficult for an individual person to remove, handle, align, and/or install a door. Additional persons and/or apparatus are thus required during such processes. In order to minimize the number of personnel needed for such operations, in some assembly or repair operations, an apparatus for supporting automobile doors and allowing work to be performed thereon may be provided. Known apparatus for supporting doors during their removal and repair have been problematic due to the potential for a door to be misaligned upon the apparatus. In an assembly line atmosphere, the misalignment and unpredictable positioning of a door upon a device can lead to inefficiency during such operations and can even be a source of danger to a user.
There are generally two types of known apparatus for supporting automotive doors during removal and repair operations. One such apparatus includes a series of clamping devices used to align and secure the door upon the apparatus. This apparatus is inefficient in use in that it requires the completion of multiple tasks by a user prior to the door being secured upon the apparatus. During the time where all of the clamps are being engaged, the door may fall from the apparatus causing damage to the door and/or potentially injure the user. Further, the multiple clamps cause variation in the points of contact with the door, increasing the potential for misalignment and/or inconsistent alignment upon the apparatus.
In another known apparatus, the door is placed on mounting beds. In this apparatus, the door is arranged onto the apparatus and is held practically upright between the mounting beds. The mounting beds are predetermined, static points of contact between the apparatus and the door. This type of apparatus has a tendency to cause damage to the door either at the points of contact, or by the door falling off the apparatus. Another drawback to the mounting bed apparatus is that the apparatus does not easily adapt to different size doors, and further, precision work is made difficult because the door is not secured, but it is merely held in place.
It is therefore desirable for an apparatus to allow a user to efficiently and consistently work upon a secured door. It is also desirable for the apparatus to be easy to use, without compromising how securely the door is supported, for the apparatus to be operable in a minimal number of steps for securing a door, and for the apparatus to be capable of securing a door without damage.

SUMMARY OF THE INVENTION

The present invention overcomes the drawbacks and deficiencies of the aforementioned automotive door support apparatus by providing an automobile door support apparatus including an apparatus support frame, and a door support frame adjustably connected to the apparatus support frame. The door support frame may include first and second support members, and an underside support member connected to the first and second support members. An underside brace may be connected to the underside support member and configured to support an underside of an automobile door. A cable rod may be provided and include first and a second ends. The first end may be configured to receive and maintain a support cable in a predetermined orientation and the second end may be adjustably connected to either the apparatus support frame or the door support frame.
