Definitions

  • the present invention relates to single-pushbutton-operated full automatic umbrella and, more particularly, to umbrella in which a single pushbutton can be operated single-handedly in automatically opening and extending the umbrella stick when it is in the closed position and in automatically closing and collapsing the umbrella when it is in the opened position.
  • an automatic umbrella belongs to either of the three following types: 1. umbrella which can be extended automatically but can not be collapsed, and which needs manual operation in closing, 2. umbrella which can be extended automatically, but needs manual operation in closing and collapsing, and 3. umbrella which can be extended and closed automatically but can not be collapsed.
  • Prior art on automatic umbrella can readily be had from, for example, U.S. Patent No. 3,856,030 to Sato.
  • the former two types of umbrella which can be opened automatically but can not be closed likewise may be designated as semi-automatic ones while the umbrella of the last type which is automatically openable and closable can be designated as full automatic one; nevertheless, the umbrella of the last type can not be collapsed, accordingly the stick of which has to be much longer and is therefore not suitable for keeping inside a case or luggage to be carried along in travelling.
  • the umbrella has two pushbuttons for operations of opening and closing respectively; as a result, an accidental touch of a wrong button often-ends in contrary action and may cause malfunction to the umbrella components.
  • the present invention is aimed at providing a full automatic umbrella which can be opened and closed, but also collapsed and contracted automatically so that its length is shortened consequently to be suitable for carrying along in travelling, and in addition, which is convenient to operate.
  • the full automatic umbrella of the present invention comprises: an inner tubular shaft member 1 having at one end a handle 11, an outer tubular shaft member 2 slidably and retractably mounted on the upper end of said inner shaft 1 and provided at the top an intermediate ring'21, an upper tubular shaft member 3 retractably inserted in the upper end of said outer shaft 2 and provided at the top thereof an upper ring 31, a sliding tubular member 4 slidably mounted on said outer shaft 2 and having at the upper end a lower ring 41, a rib assembly 5 having collapsible ribs couplingly and collapsibly pivoted at the upper ring 31, intermediate ring 21 and lower ring 41, a control unit 6 housed in said inner shaft 1, adapted for controlling the opening and closing of-the umbrella by operating a control ring 61 provided at the upper end of the handle and a first coil spring 7 disposed between the intermediate ring 21 and the lower ring 41 and the two coil springs, second and third, 8A, 8B located in the lower inner

  • the lower end of one side of said shaft 2 in relation to the V-shaped guide-groove 10 is formed by press-molding with an inwardly projecting portion 23 to provide a means for engagement with afore-said engaging member 18 in preventing the lower inner shaft 1 from slipping out of the outer tubular-shaft 2.
  • a further opening 25 is defined in one side near the middle portion of the outer shaft 2 and accommodated therein the spring pawl 66 has the upper end fixedly attached to the wall of -said shaft and the free end protruding outwardly from said opening 25 to be engaged with aforesaid sliding tubular member 4.
  • the upper inner tubular shaft 3 has an upper ring 31 mounted on its upper end-while its lower end is retractably inserted in the upper portion of the outer tubular shaft 2.
  • the sliding tubular member 4 is a short piece of tube having at the upper end a lower ring 41 mounted thereon and in the wall of the lower end portion relative to the notch 22 of the outer tubular shaft 2 formed with an opening 42 to be engaged with the locking head 153.
  • the rib assembly 5 comprises a plurality of first main ribs 51 having each one end pivotably connected to the upper ring 31 and each of the other end extending downwards, a plurality of first auxiliary ribs 52 having each one end pivotably connected to a cramp fitting 51a disposed in slightly to the middle of said first main ribs 51, a plurality of the second main ribs 53 having each-upper end pivotably connected to each of the other end of said first auxiliary ribs 52 and the lower end being free and extending downward, a plurality of supporting ribs 54 having each one end pivotably connected to the lower ring 41 and the other end pivotably connected to the cramp fitting 53a disposed in close to the upper portion of said second main ribs 53, and a plurality of second auxiliary ribs 55 having each one end pivotably connected to the intermediate ring 21 and'the other end pivotably connected to the cramp fitting 54a disposed in slightly to the middle of the supporting ribs 54 and whereto the lower end of the first main ribs also pivotably connected.
  • the control unit 6 comprises a control ring 61 being axially and slidably mounted on the lower end of the lower inner shaft 1 above the upper portion of the handle 11, a sleeve 65 being slidably housed in the outer tubular shaft 2 in slightly the upper portion with one side of the lower portion thereof provided with an axial slot 651, a spring pawl 66 having one end fixed to the upper end of the sleeve 65 and the free end protruding out in aforesaid axial slot 651, an actuating member 62 having a space 621 between the two side walls with the spring pawl 66 engaged therein, a pulling rod 63 being disposed in the lower inner shaft 1 and'the outer tubular shaft 2 with one end thereof being connected to the lower end of the actuating member 62 by a pin 67 and the other end thereof formed with a hook end 631 to be accommodated in the center cavity 13 of the handle 11, and a return spring 68 being disposed in between the control ring 61 and the handle 11.
  • control ring 61 is provided with a tubular portion 611 which is retractably inserted in the center cavity 13 of the handle 11 and which at the inner end is fixed with a pin 612 adapted to be hooked over by the hook end 631 of the pulling rod 63.
