TODAY’S PATENT – SIGN POST

The sign post was invented by Duane D. Barth was assigned Heritage Products Intl., Inc., which was granted patent on Apr 27, 1982 by the USPTO bearing the patent  number US4326352A.

A sign post has a hollow post with a cross arm assembly inserted into the upper end of a post and a stake inserted into the lower end. Hooks and a slotted member are attached to the horizontal tube of the cross arm assembly. To make the cross member, a vertical guide member is inserted through a hole in a horizontal support member and fastened to that member. The vertical guide member is sufficiently long to extend both above and below the horizontal support member. A cap member fits about the upper portion of the vertical guide member.

Additionally, a slotted member is attached to the top of the horizontal support member with threaded hooks inserted through holes from the bottom side of the horizontal support member. This allows one sign to be hung from the hooks below the horizontal support member and another sign to be inserted into the slot of the slotted member above the horizontal support member. The stake component has smaller cross-sectional dimensions than the post. It has metal expander elements attached in a spaced apart relationship on its upper portion. The outer contour of the expander elements allow the post to slide snugly over the stake and expander elements.
