Abstract
An elongated safety bar comprises first and second spaced apart flanges and first and second webs which interconnect the associated side edges of the first and second flanges, the second flange, when viewed in cross section, including a flat central portion, and the first flange, when viewed in cross section, including a central portion which is parallel to the flat central portion of said second flange, and opposite generally semicircular end portions, these end portions extending away from the side of an imaginary plane defined by the flat central portion of the first flange opposite the side facing of the second flange. The second flange is longer, viewed in cross section, than the first flange, thus providing the safety bar with a closed, generally trapezoidal-shaped cross section.
Claims10
An elongated safety bar which is resistant to lateral deformation in a collision, said elongated bar including first and second spaced apart flanges which extend the length of said safety bar and first and second webs which extend the length of said safety bar, the first and second webs respectively interconnecting the associated sides of said first and second flanges so as to provide said safety bar with a closed, generally trapezoidal-shaped cross section;
- said second flange, when viewed in cross section, defining a flat central portion and opposite end portions;
- said first flange, when viewed in cross section, defining a flat central portion and opposite end portions, said central portion of said first flange being parallel to said flat central portion of said second flange, and said opposite end portions of said first flange being generally semi-circular in shape and extending away from an imaginary plane defined by the flat central portion of said first flange on the side thereof opposite the side facing said second flange;
- said second flange, when viewed in cross section, being longer than said first flange, such that said first and second webs diverge from one another as they extend from said first flange to said second flange;
- said elongated safety bar being resistant to buckling by forces applied against said semi-circular end portions of said first flange and in the general direction of said second flange.
