Abstract: A pushbutton switch for use in a keyboard attached to a computer system, word processor, electric typewriter, etc., is implemented to give the operator both a tactile feel and a click sound when a key is entirely depressed. The switch comprises a housing, an actuating arm, a stem and a leaf spring mechanism. The leaf spring has an upright portion with a hook, a bent portion, a spring portion and a protruding portion. It is mounted in the housing such that when the stem is partially depressed, it forces the upright portion to slant toward the inner surface of side wall of the housing and the spring portion to be compressed. When the spring is depressed beyond a certain position, the protruding portion of the leaf spring slips off the ledge of the step portion of the side wall of the housing, causing the bent portion to snap toward and collide with the outer surface of the stem, thus producing the desired click sound.

Abstract: An article carrier attachable to a front brace of a walker and composed of a flexible material whereby the article carrier is foldable with the walker as the walker is collapsed for storage or transport. The article carrier has front and rear panels which extend generally over the width of the walker and has side panels the width of each of which is less than about 5 inches to reduce instability effects of the carrier which might otherwise result if the carrier were positioned too far outside of the space between the walker legs while at the same time reducing the space taken up by the carrier between the walker legs so that more comfortable use of the walker may be afforded the user. Tabs are provided on the side panels to attach to the respective front legs of the walker to prevent "bunching" of the article carrier toward the center. Thus, increased mobility may be provided to the user for a more independent and higher quality life.
