Abstract
The disclosed signal device has a base plate and a signal plate, each plate having a threaded member secured relative thereto. A helical coil spring is threaded onto the respective threaded members, to become fixed between said base and signal plates. The signal plate has adjacent an edge remote from the spring, a tab portion angled about an axis disposed transverse to the threaded member. A double sided adhesive tape, bonded on one side to the face of the base plate remote from said spring, has the other side on the base plate, but it is yet covered by a removable facing. After removing the tape facing, the base plate may be positioned with the adhesive side against the exterior wall structure of a roadside mailbox, at a suitable spacing from the adjacent open end and door of the mailbox. Thus, when positioned, the signal plate and tab may be moved according to the flex of the spring, to a lowered position where the tab may be locked adjacent the closed door of the mailbox, to hold the signal plate set in the lowered position. The signal plate tab, upon said door being opened, is released to allow the signal plate to be moved automatically by the flexure of the spring to an elevated position upstanding from the mailbox, to be visible from afar. The elevated signal flag may advise that the mail carrier has deposited mail in the mailbox.
