Abstract: In combination with a body defining an annular space and a member received for rotation or linear movement within the annular space, an annular seal arrangement includes a first sealing member defining a first sealing portion disposed in constant engagement with a peripheral surface of the member during the rotation or the linear movement thereof, a second sealing member defining a second sealing portion disposed in constant engagement with the first sealing member and radially aligned only with the first sealing portion, and a fluid pressure directed at least onto the second sealing member, whereby the second sealing portion is configured to bias the first sealing portion into the constant engagement with the peripheral surface of the member.

Abstract: A portable motorcycle covering for enclosing and protecting therein a motorcycle includes an elongated floor cover on which the motorcycle rests, and the floor cover has a circumferential lip to prevent water from coming on to the floor cover. A flexible and collapsible protective cover is integrally attached to at least one half of the floor cover and is capable of pivotal movement between an open position, wherein the motorcycle can be placed on the floor cover, and a closed position, wherein the motorcycle is fully enclosed by the protective cover. A plurality of u-shaped crosspieces create a support frame for the protective cover, and the crosspieces pivot in sequential order for creating the support frame and deploying the protective cover when the leading crosspiece positioned adjacent the opening of the protective cover is grasped and pivoted by the individual.
