Abstract
Abstract A handle device includes a tube, a seat secured to the tube and having a channel for slidably receiving one end of one or more hand grips. The hand grips each has a slot for slidably receiving a fastener which is engaged through the hand grips and for allowing the hand grips to be folded to a compact folding position. The fastener has a neck engageable into the hand grip for solidly securing the hand grips to the seat. A bar is engaged onto the hand grip, and a quick release fastener is engaged through the bar and secured to the seat for clamping the bar to the hand grip.
