<p>An umbrella includes ribs (07), supporting rods (05a, 05b) for placing a cloth cover thereon, connecting rods (06) for supporting the ribs, a main strut (01), and an inside control rod (10). The supporting rods are jointed and are connected with the ribs at the upper ends, and also with a holding ring (02) on the lower ends of the main strut. The connecting rods (06) ae installed between the supporting rods and a holding ring (04) which can move up and down on the main strut where the ribs are installed. The main strut (01) comprises a tube having an open-close control rod (10) inside which can also move up and down. A retractable spring (15) is installed at the end near the umbrella tail portion. An exposed pushable knuckle (100), a reed-dent or latch device (100a) and a latch-like snap pin (11) are disposed on the control rod. When the umbrella is opened, the snap pin is pressed into the strut interior by the slidable holding ring (04) and springs outside when the umbrella is closed. It will stay beneath the holding ring to prevent the ring from further sliding down or to prevent extra extending of the ribs. The open-close control rod (10) and slideable holding ring (04) are jointed together with a pin (14) which extends through aligned grooves (012) in the main strut provided for the slidable holding ring to move up and down. There are three openings (010a, 010b, 011) on the main strut which provides positioning for the knuckle, the reed-dent device and the snap pin with checking effect.</p> |
