ABSTRACT:
An extendible handle assembly for an umbrella includes an adapter for coupling to a shaft and a sleeve. The sleeve has a series of grooves, and the adapter has tabs which move within the grooves. The adapter and the shaft move axially relative to each other in order to extend the length of the handle. In another embodiment, the handle construction has an adapter, an inner sleeve, and a shell. The adapter and inner sleeve each have tabs which mate with grooves in the inner sleeve and the shell, respectively. The adapter may be rigidly coupled to the shaft with threads, or may have a switch operated opening mechanism.
