Abstract
Abstract A plurality of sign various sizes of sections are similarly formed so that a plurality of selected sign sections may be positioned vertically and/or horizontally abutting such as a lower first and intermediate second both secured to spaced, vertical ground supporting posts and the intermediate second and an upper third both secured to spaced, vertical tying members. Each sign section has spaced, front and rear, sheet-like face panels adhesively secured internally to a honeycomb core and at edge portions to upper, lower and side border members extending between the face panels. Each sign section has opposite unitary border members having in transverse cross section upper U-shaped and lower inverted U-shaped portions vertically spaced by a central vertical portion, a longitudinally extending, C-shaped chamber being formed between the upper and lower portions and rearwardly of the vertical portion opening rearwardly through a vertically intermediate, horizontal slot formed by flange extensions of the upper and lower portions. These C-shaped chambers are dimensioned for slidably and nonrotatably receiving heads of fastening bolts therein through enlarged slot openings with shanks of the bolts projecting rearwardly through the slots for securement to the ground supporting posts or tying members or both. In vertically abutting sign sections, the side border members are vertically extending and outwardly opening, U-shaped cross section extending vertically upwardly covering end extremities of the upper border members with water drain openings being formed through the side border members horizontally into the upper portions of the upper border members. Between abutting sign sections, H-shaped cross section alignment members are positioned partially in each of the opposed open border member portions retaining alignment between the abutting sign sections.
