Abstract: A chin protection system for releasable attachment to a wide variety of helmets through the use of an elastically-deformable helmet cover, a pliable retainer, and a chin protector. The system safely attaches to a helmet without any modifications to the helmet and therefore does not impact the warranty or safety rating of the helmet. The helmet cover is designed to stretch and conform to numerous different helmet styles and manufacturers, while serving as an attachment point for the pliable retainer. The pliable retainer provides the tensile force necessary to keep the chin protector in place throughout the range of movement common during sporting activities, as well as during an impact to the chin. The chin protection system may be utilized on any safety helmet including, but not limited to, bike helmets, skateboard helmets, rollerblade helmets, ski/snowboard helmets, motorcycle helmets, go-cart helmets, baseball and softball helmets, and climbing helmets.

Abstract: A molded mailbox having a curved top surface includes flattened vertical surface projecting from each lateral side each sized to receive a decorative plate having a corresponding flattened undersurface. Attachment and detachment is readily achieved by either blind holes formed in the flattened vertical surface that do not compromise the moisture resistance of the mailbox. Through holes in the decorative plate allow insertion of a fastener (e.g., bolt, screw, push-in fastener). Alternatively, attachment is achieved by a flange molded about three sides of the flattened vertical surface to slidingly receive the decorative plate.
