Abstract: A door strut construction includes a strut having a top cross wall connecting lateral side walls that are part of a truncated isosceles triangle and wherein the lateral cross wall joins first and second spaced pylons attached to the top edge of the side walls and further wherein the bottom edge of the side walls include projecting plate members having upstanding, outside lips for reinforcement. The strut further includes lateral ribs positioned in the upper half region of the side walls to improve torsion resistance.

Abstract: Adjacent panels of a folding door included opposed edges having a tongue and groove, pinch proof construction. The panels are formed of spaced sheet metal sections with an insulating form between the sections. The panels are hinged along their opposed side edges by hinges with attachable bracket and brace members for support of edge mounted rollers and reinforcing cross braces.

Abstract: The present invention relates to a pinch-proof garage door for protecting human fingers from being pinched. The garage door includes a plurality of horizontally aligned garage door panels. Each garage door panel has a male portion and a female portion, wherein the male and female portions cooperate with each other to such a manner so as to minimize a gap therebetween. Each garage door panel is removably connected together by a hinge assembly which cooperates with an the garage door panels so as to prevent human fingers from being pinched by the inside of the garage door.

Abstract: A series of rectangular horizontal, garage door panels are joined together by an integral hinge construction which enables the panels to be manufactured at a factory site and assembled at a construction site. The panels as well as the hinge elements may be fabricated from a fiberglass, reinforced, composite or other polymeric materials to enhance the durability of the garage door construction.

Abstract: A door assembly having articulated segments includes at least one support assembly for bracing the door assembly against lateral forces. This support assembly includes guide members secured to the door segments and articulated locking members disposed in sliding relation with the guide members. The locking members move between a first predetermined position in which they allow the door segments to pivot with one another and a second position in which they bridge the door segments and prevent them from pivoting with one another.

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.

Abstract: A door assembly includes an articulated door with rollers mounted along its edge portions and guide and support tracks for securing the door to a wall with an opening that the door closes. The assembly also includes bracket members for supporting the door when a load displaces the door a predetermined distance in a direction generally perpendicularly to the face of the door when the door lies in a closed position.

Abstract: A closure apparatus for closing an opening in a partition with a frame disposed around the opening includes a drum member rotatably mounted to the partition at the top end of the opening. It also includes a curtain member secured to the drum member. The curtain member winds around the drum member to move out of the opening in the partition; and it extends from the drum member to close the opening. A counterweight connected to the drum member offsets the weight of the curtain member; and a reducing weight reduces the weight of the counterweight to allow the curtain member to drop from a raised position. An activating assembly engages the reducing weight with the counterweight and allows the curtain member to unwind from the drum member and close the opening.
