发明名称 Safety rail for collapsible bleachers
摘要 A collapsible bleacher safety railing for use in conjunction with collapsible bleacher assemblies which are well known and in common use. The railing includes vertical upright support members on which are mounted telescoping hand rail sections therebetween and which include safety panels mounted between the support members below the hand rail. The safety panels eliminate the need for multiple guard rails or comparable guard members and extend and collapse with the bleacher assembly. In one form of the invention, the top edge of the planar safety panel may replace the telescoping hand rail. The vertical support members are preferably angle bars positioned to nest together upon collapse of the bleacher. An improved form of safety hand rail is disclosed.
