Patent attributes
An upright type vacuum cleaner has a locking to selectively restrain the pivoting of a handle assembly when the handle assembly is pivoted to be in a right angle with respect to a base. The locking device includes a locking portion disposed at a side of the base, a locking protrusion movably disposed at the handle assembly and selectively moving between a locking position where the locking protrusion contacts with the locking portion and an unlocking position where the locking protrusion releases out of the locking portion, and a pedal member pivotably disposed at the handle assembly to move the locking protrusion. As the pedal member is disposed at the handle assembly, the size of the base can be reduced and the manipulation of the pedal member becomes easy.
