  • the other end of the second pulling rope ( 34 ) extends through an opening ( 321 ) of a connecting tube ( 32 ) and then passes by the roller ( 331 ) of the sliding element ( 33 ) and eventually returns to the connecting tube ( 32 ) and is tied to the opening ( 321 ).
  • the bullet-shaped plunger ( 35 ) has a reduction segment ( 352 ).
  • a hollow guide tube ( 36 ) is disposed in the driving portion ( 30 ), with the bullet-shaped plunger ( 35 ) pressing against the lower end of the guide tube ( 36 ).
  • the guide tube ( 36 ) transmits a compression force to the spring ( 16 ) in the umbrella rod portion ( 10 ).
  • the actuating portion ( 40 ) is used to provide gripping convenience to users. It comprises an inner seat ( 41 ), a retainer ring ( 42 ), a movable block ( 43 ), an intermediate element ( 44 ), a push button seat ( 45 ), a push plate ( 46 ), an inner tube ( 47 ) and a lock plate ( 48 ). With this actuating portion ( 40 ), users can urge the push plate to actuate the opening and closing operation of an umbrella.
  • the inner seat ( 41 ) is a hollow block with one end extended to form a tubular portion ( 411 ). Inside the inner seat ( 41 ) near the upper end is a groove ( 412 ) extending along the inner wall. Two protrusions ( 413 ) are symmetrically disposed on opposite wall surfaces and extend to the tubular portion ( 411 ). Further, a slot ( 414 ) is provided on the inner wall surface at a proper position.
  • a retainer ring ( 42 ) is generally a loop with a slant raised block ( 421 ) on one side.
  • the retainer ring ( 42 ) is situated in the groove ( 412 ) of the inner seat ( 41 ) to press against a spring ( 422 ) by the slant raised block ( 421 ).
  • the movable block ( 43 ) is provided on the center with an axial hole ( 431 ), on a pair of opposite sides with a bulged strip ( 432 ) and an opening ( 433 ) respectively, and on another pair of opposite sides with a curved recess ( 434 ).
  • a spring ( 435 ) is disposed under the movable block ( 43 ) to support it and two curved recesses ( 434 ) are engaged with two protrusions ( 413 ) so that the bulged strip ( 432 ) can move in the slot ( 414 ) under the guidance of protrusions ( 413 ).

  • the bullet-shaped plunger ( 35 ) is locked and thus the first and the second pulling ropes ( 31 , 32 ) can move relative to each other with the aid of the roller ( 331 ) of the sliding element ( 33 ) and the pulley ( 151 ) of the coupling tube ( 15 ). Thereby, the pulling ropes can be fully extended.
  • FIG. 7 the movements of closing the umbrella are shown.
  • users want to close and collapse the umbrella they just need to depress the push plate ( 46 ) of the actuating portion ( 40 ) once again.
  • Depression of the push plate ( 46 ) makes the intermediate element ( 44 ) squeeze the spring ( 443 ) and urges the stud ( 442 ) of the intermediate element ( 44 ) to get into the opening ( 433 ) and to move the bullet-shaped plunger ( 35 ).
  • the bullet-shaped plunger ( 35 ) loses the constraints of the hook portion ( 481 ) of the lock plate ( 48 ) and rises quickly. This can be seen from FIGS.
  • the multiple folding umbrella structure according to the invention not only has easy-to-operate and quick-to-response advantages but also has the merits of simple constituents and low cost in manufacturing and assembling. It is particularly suitable for mass production. It indeed has the essence of a patent and thus we hereby apply for a patent grant.
