  • Patent number: 6996888
    Abstract: A method for displaying an advertisement panel upon a road barrier having a base, a vertical partition having front and rear surfaces, and transverse cavities extending between the surfaces, using a display assembly having a panel sleeve and a pair of mounting brackets for securing the sleeve against the barrier. Each mounting bracket has an insert for extending partially into the transverse cavities. One mounting bracket is mounted against the vertical partition front surface and the other against the vertical partition rear surface. The inserts of the mounting brackets are simultaneously brought into close proximity within the cavities and are mated to hold the brackets and the panel sleeve securely against the vertical partition. The panel sleeve is secured to the mounting bracket and has a horizontal top lip and a horizontal bottom lip. The advertising panels may be easily inserted therebetween for display and removed when desired.

  • Patent number: 6763626
    Abstract: An advertising display system, for use with a portable toilet housing having four walls and four corners connecting the four walls. A bracket assembly is attached vertically along each corner. At least three panel assemblies are each selectively mounted between two of the bracket assemblies such that each panel assembly arcs outward to create a substantially semi-cylindrical configuration by the panel assembly which spans across one of the walls. Each panel assembly includes outer panels and a changeable printed sheet extending therebetween. Each bracket assembly includes a T-bracket which provides a space between the T-bracket and the corner of the portable toilet housing to secure one of the panel assemblies therebetween.
