  • Patent number: 10037718
    Abstract: A sign post and sign system comprising a base may be connected to a vertical post. A four-way connector may attach horizontal stems to the vertical post. Rotatable or non-rotatable fasteners may be positioned on the upper or lower side of the horizontal stems. Rotatable fasteners may be connected to the horizontal stems to support rotation of a connected sign in an axis parallel to the horizontal stems. A one piece or two-piece cap design may be connected to the four-way connector. Lights, wiring, batteries, and/or a solar panel may be integrated into the sign system. A sign may be attached between the vertical post and the horizontal post to support rotation of the connected sign in an axis parallel to the vertical post. Rotatable fasteners may be connected to the horizontal stems to support rotation of a connected sign in an axis parallel to the horizontal stems.
