Abstract: A mobility device configurable in a first walk configuration and a second stair-climb configuration, including a frame with movable front leg portions, a leg-actuation system connected to the front leg portions and a safety-control device mounted to the frame. The safety-control device includes a configuration selector, and a lever connected to the leg-actuation system and configured to actuate the cable actuation system so as to cause the first and second movable leg portions to move from a first position to a second position. The lever remains locked in a first lever position such that the lever cannot be moved unless the configuration selector is in a depressed position, thereby preventing inadvertent movement of the leg portion.

Abstract: A double opening bag utilizes a single draw cord for closing both ends. The draw cord passes around the periphery of a tubular section of the bag adjacent the two ends. The draw cord extends closely alongside the tubular section when the openings are open. Pulling the draw cord closes both ends and creates slack in the draw cord. The slack is sufficient to serve as a shoulder strap for carrying the bag over a person's shoulder. A partition may be added to the interior of the bag generally between the ends to create two open-ended compartments that close simultaneously with the tubular section ends when the draw cord is pulled.
