ABSTRACT:
The invention relates to a dual locking mechanism for umbrella handles that is provided inside an umbrella handle to engage the locating hole of an umbrella runner. Normally, the locking mechanism is used as the securing means to hold the runner in a position where the umbrella is close. If the umbrella will be kept in a storage place for a long duration, users can further press the runner into the handle to alter the umbrella to its most compact configuration thereby saving space and providing convenience of storage.
