Abstract: A new helmet mirror comprises an articulated two-piece body having the mirror on one piece and an attachment device on the other piece. For most applications the attachment device comprises an adhesive for attachment directly to the clear face shield of a snowmobile helmet. The mirror and the adhesive are on the back of the respective pieces and the fronts of the respective pieces are smoothly contoured to reduce wind resistance and aerodynamic forces applied to the mirror body at high speeds. In an alternative embodiment a third piece comprising a link joins the mirror piece to the attachment piece with two articulation joints. The link is aerodynamically shaped to substantially reduce vibration of the mirror at high speeds and thereby reduce the forces applied to the articulation joints which retain the mirror in the proper viewing position.

Abstract: Electrical plug and socket assemblies for interconnecting electrical cables and extension cords comprising one or two piece molded bodies that form a streamlined bulbous shape when engaged. The plug and socket are engaged by pulling in substantially opposite directions and disengaged by pushing apart. The engagement of the plug with the socket thus tightens when the cables are pulled as distinguished from a conventional plug and socket. The molded plastic portions of each one or two piece plug or socket body are identical, the metal prongs or contacts being insertable during assembly to make a plug or socket respectively. The one piece body includes a hinge joining the outside female portion to the inside male portion and can be molded as one unit. The two piece body is identical except for the deletion of the hinge joining the pieces. Upon assembly of the cable and prongs or contacts into the male portion, the male portion is folded and secured into the female portion.
