20130062585 | PORTABLE SAFETY RAIL SYSTEM - A portable safety rail system includes one or more railings inserted into one or more stackable rail bases. Each rail base can include a plurality of apertures for receiving end rail posts of railings through a raised hub defining an open region between the bottom of the hub and the surface on which the rail base rests. Each end rail post can have a stop flange that engages an upper surface of hub when inserted therein and an aperture through the end portion that extends into the open region beneath the hub for receiving a pin to lock the post while allowing rotation of the post. System can also include toe boards that are attached to railings with a mount having an aperture through which railings are extended, allowing the toe boards to also be rotated to be aligned with railings. | 03-14-2013 |
