  • Installation method for a storm door
    Patent number: 7661226
    Abstract: The present invention is a system and method for an easy installation storm door for installation in a home. The door system may include a door panel that is mounted onto two vertical z-bar frames such that the door system can be installed in a left hinge or right hinge format. The z-bar frames are precut at the factory to be shorter than a standard doorframe so that they do not have to be cut during installation. Also included in the system are top and bottom expanders that fit onto a top and bottom side of the door panel so as to selectively adjust the vertical height of the door panel. The top and bottom expanders further insure a reasonable air and moisture barrier between the interior and exterior of the home. The door system further includes a lock assembly that is pre-installed such that it can be utilized whether the door system is installed in a left hinge or right hinge format.

  • Reversible door having mortise hardware
    Patent number: 7117639
    Abstract: A reversible door (10), having a defined top, includes two notches (11, 12) on opposite sides of the door.

Then, a mortised handle assembly (15) is positioned through the holes formed in the notch. A hinge assembly is secured to the opposite side of the door from the handle assembly. A snap cover (14) is positioned in the notch that does not have the handle assembly (15).
