<p>A safely operable handle device includes a grip shell (200) coupled to a telescopic central shaft unit (300), a retained block (720) releasably blocked so as to hold the umbrella in an opened state, a reel member (10) rotatably mounted in the grip shell (200) and biased by a coil spring (30), a cord (20) reelable on the reel member (10) and coupled to one of a top notch (400) and the retained block (720), an actuator (43), and a unidirectional retaining mechanism. Upon application of a pressing force to telescopically fold the central shaft unit (300), and upon movement of the actuator (43) in response to a stroke movement of a push button (45), the reel member (10) turns in a counterclockwise direction to reel in the cord (20), and is prevented from turning in a clockwise direction so as to hold the central shaft unit (300) in position to thereby avoid undesirable extension of the central shaft unit (300).</p> |
