Abstract

A sectional door is disclosed that includes a safety system. The safety system includes a shield apparatus, an improved support track, reverse angle track shields, and hemmed roller track edges to prevent injury or harm to body parts errantly placed within or around the support track during the opening or closing of the sectional door. The sectional door includes a plurality of door sections hingedly joined in an edge-to-edge relationship to form the completed sectional door. The sectional door further include support rollers attached to the door sections, and a pair of support tracks, in which the support rollers are confined. Each support roller further includes a circular or rectangular roller shield that is mounted to the axle of the support roller outside of the support track where it is proximate the support track in such a manner as to limit or prevent any fingers from engaging within the support track with the support rollers. The dimensions of the protective shield is larger than the support rollers so as to provide adequate shielding for the support roller. Protective shield wings are provided to enclose the support track and prevent objects from interfering with the roller as well as to provide transport guidance within the support track where track sections meet. Further, the outer edge of the protective shield is blunted or protected in a manner to prevent harm during operation. The reverse angle track shields are constructed of a solid metal piece so as to prevent objects from passing between the support track and a mounting surface. Additionally, the adjacent edge of the support track is also formed into a folded single hem, either outwardly or inwardly, to prevent fingers from being cut as the fingers are brushed aside by the roller shield.
