Abstract
A pop-up mechanism is provided for use on the extendable handle of a wheeled luggage case to allow the extendable handle to be extended out in a pop-up manner that allows the user to easily grip the handle to pull the luggage case on the ground. The pop-up mechanism is simple in construction than those in the prior art so that the manufacture and maintenance can be easily carried out. The pop-up mechanism of the invention includes a fastening device mounting on one of the tubes and an elastic driving device secured to the fastening device. The elastic driving device is formed with a cavity in which an elastic means and a slidable block seated on the elastic means are mounted. The slidable block is slidingly movable in the cavity. When the extendable handle is in a retracted position, the slidable block is urged to compress the elastic means and thus being moved downwardly to a lowest position; and when unlocked, the compressed elastic means is expanded to cause the slidable block and the elongated bars of the extendable handle to be popped up. By utilizing this pop-up mechanism, the assembly and disassembly of the component parts of the pop-up mechanism are easy to carry out, resulting in a reduction in the manufacturing and maintenance costs.
