Abstract: An air conditioner cover, for covering an air conditioner having an air conditioner face, comprising a main housing defining a main cavity which is sized to cover a portion of the air conditioner rearward of the air conditioner face. The main housing has a front panel, four peripheral walls, and a mouth opening opposite the front panel. A flange extends perpendicular to the peripheral walls at the mouth opening. A seal comprising four angled gaskets extends around the mouth opening, each angled gasket extending from one of the peripheral walls and having a triangular cross section. The angled gaskets allow the air conditioner to easily slide into the mouth opening until the air conditioner face meets the front panel, but resists removal therefrom, to hold the air conditioner cover securely upon the air conditioner. The front panel has a decorative covering to match the decor of the room in which the air conditioner is located.

Abstract: An environmental shield secureable to a helmet, protecting a wearer. The helmet includes a rigid outer shell and a perforate liner positioned within the outer shell, leaving a space between a portion of the outer shell and the liner. The environmental shield can include a flexible sheet like main portion that shields the wearer when worn secured to the helmet. This shield includes an attaching portion of the main portion that is configured to secure the shield to the liner of the helmet in such a way that preserves the space between the liner and helmet so that air can flow into the helmet. Alternatively, the environmental shield can include a quadrilaterally shaped flexible sheet like main portion. This shield has two elongated flaps along one side of the main portion. Receded regions extend along adjacent sides from the flaps, and sloped so that the width of the shield increases. Shoulders protrude from the receded regions increasing the shield's width.
