  • Patent number: 5729866
    Abstract: A retractable handle assembly for a suitcase includes a handle with an actuating member. Each end of the actuating member is connected to an end of a rod which is received in an inner tube slidably received in an outer tube. The outer tube has an inner side with a plurality of protrusions extending radially therefrom so as to define a plurality of recesses. A first member disposed on the other end of the inner tube has a top from which a flexible plate depends. The plate has a block disposed at a distal end. The second end of the rod is connected to a second member. The second member pushes the block against the inner side of the outer tube. When the actuating member is lifted, it lifts the rod and frees the block. The inner tubes can then be lifted.
