Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a door panel assembly, and more particularly to a door panel assembly having flexible hinge members for flexibly coupling door panels together.




2. Description of the Prior Art




Typical door panel assemblies may comprise a number of parts or elements that may be assembled together, and that may be coupled to the other door panels. For example, U.S. Pat. No. 5,634,998 to Schiedegger et al. discloses one of the typical door panel assemblies having a number of parts or elements to be assembled together. However, the door panels include a solid structure that may not be foldably or flexibly coupled to the other door panel devices.




The applicant has developed another typical door panel assembly which has been issued as U.S. Pat. No. 5,782,282 to Chen, and which includes two or more door panels that may be foldably coupled together, for allowing two or more door panel assemblies to be foldably or pivotally coupled together. However, the door panels may be folded relative to each other, but may not be flexibly coupled together.




The applicant has further developed the other typical door panel assembly which has been issued as U.S. Pat. No. 6,330,902 B1 to Chen, and which includes two or more door panels that may be flexibly coupled together with flexible links, for allowing two or more door panel assemblies to be flexibly coupled together. However, the flexible links of the door panels are slidably engaged in the door panels and may not be solidly secured to the door panels.




The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional door panel assemblies.
