  • Patent number: 5782283
    Abstract: A pinch-proof garage door for protecting human fingers from being pinched is disclosed. The garage door includes a plurality of horizontally-aligned garage door panels. Each garage door panel has a top male portion and a bottom female portion. Top male and bottom female portions of adjacent garage door panels cooperate with each other in such a manner so as to minimize a gap therebetween, thereby protecting human fingers from being pinched by both the inside and the outside of the garage door. Each garage door panel is securely fastened to a structural member which supports the weight of the panel. Adjacent structural members are vertically aligned with one another and are coupled together by a hinge pin and hinge leaf. Each structural member cooperates with an adjacent hinge leaf so as to prevent human fingers from being pinched by the inside of the garage door.

  • Patent number: 4589240
    Abstract: A door panel having an insulating foam core and a pair of rigid inner and outer skins preferably formed of steel or other metal. The skins have side flanges with hook portions that mechanically interlock. The interlocking flanges provide a method of mechanically attaching the inner and outer skins of the panel to each other by utilizing the compression and spring back of the core during assembly. A resilient thermal barrier element is interposed between the interlocking flanges to prevent them from making direct contact with each other while at the same time sealing the joint, the thermal barrier element also including a cushioning bead engagable with a similar bead of another door panel to provide a weather seal therebetween. The method of making the panel is also disclosed.
