ABSTRACT:
An integrated handle for telescoping tubes includes a handle assembly, at least one ball housing assembly, at least one connecting rod, and at least one set of telescoping tubes. The handle assembly comprises a handle, a cover, a button, and at least one lever. The ball housing assembly comprises a ball housing, a cam rod, a spring, and at least one ball. The cam rod slidably fits inside the ball housing. An upward movement of the cam rod forces at least one ball out, a downward motion allows retraction of at least one ball. The set of telescoping tubes comprises an upper and lower telescoping tube. The lower telescoping tube has a plurality of locking holes disposed at different heights. At least one upper telescoping tube is fastened to the bottom of the handle. When it is desired to extend or retract the integrated handle for telescoping tubes, the button is depressed which pushes the cam rod in a downward movement through the connecting rod and releases force on at least one ball contained in the ball housing. When the button is released, at least one ball is forced outward by the cam rod and locks into at least one locking hole disposed in the lower telescoping tube.
