  • This invention relates to a collapsible umbrella which can be automatically opened in a single operation.
  • Collapsible umbrellas are known which comprise foldable ribs and a stick which is made up of two or three sections telescopically slidable into and out of one another, so that the umbrella can be collapsed to a compact overall size.
  • collapsible umbrellas of the prior art are difficult to open from the collapsed state. Particularly, it has been difficult to open a collapsible umbrella of the prior art by one hand.
  • Other disadvantages of collapsible umbrellas of the prior art include the reduction of mechanical strength of the umbrellas due to their collapsible construction and the difficulty with which the ribs of the umbrellas can be brought to their extended positions.
  • a principal object of this invention is to provide a collapsible umbrella which can be opened automatically by one hand by merely depressing a button by a finger.
  • Another object of the invention is to provide a collapsible umbrella of the type described which can be not only opened automatically by pushing a button but also collapsed by a single operation by applying pressure to the portion of the stick of the umbrella ranging from the ferrule to the handle.
  • the aforementioned objects are accomplished by providing the umbrella with a stick which is made up of three sections or outer, intermediate and inner sections which are telescopically slidable into and out of one another.

  • the intermediate stick section mounts therein a second spiral spring of different biasing force from the first spiral spring which is connected at one end to the upper end of the intermediate stick section and abuts at the other end'against a plug blocking the upper end of the inner stick section.
  • the upper rib supporting member secured to the upper end of the outer stick section pivotally supports main rib portions each of which is pivotally connected to a forward rib portion through sliding means which pivotally supports a holding rib connected to a supporting rib.
  • the holding ribs and supporting ribs are pivotally connected to an intermediate rib supporting member and a lower rib supporting member respectively which are slidably fitted over the stick sections.
  • a third spiral spring is mounted between the intermediate rib supporting member and lower rib supporting member.

  • 22a is a pin for pivotally connecting the base of each forward rib portion 17 to the lug 22
  • 23a is a pin for pivotally connecting the other end of each holding rib 18 to the lug 23.
  • each of the holding ribs 18 is pivotally connected at one end to the outer lug 23 of an associated sleeve and at the other end to the intermediate rib supporting member 24 which is adapted-to move up and down in sliding motion along the outer, intermediate and inner stick sections 1, 3 and 4.
  • the member 24 is formed integrally at its lower end with an annular seating portion 25 and at its upper end with a cylindrical portion 26.
  • Each holding rib 18 has secured at its central portion a hinge assembly 27 which pivotally supports one end of one of the supporting ribs 19, the other end of said supporting rib 19 being pivotally connected to a lower rib supporting member 28 which is disposed below the intermediate rib supporting member 24 and adapted to slide along the outer, intermediate and inner stick sections 1, 3 and 4.
  • the lower rib supporting member 28 is integral with a cylindrical member 29 which is loosely fitted over the stick sections.
  • the cylindrical member 29 is integral at its lower end with a reduced portion 30 formed with two axially aligned openings 31 and .31.
  • 32 is a third spiral spring mounted between the lower end surface of the annular seating portion 25 and the upper end surface of the reduced portion 30.
  • 33 is a locking member inserted in the lower end portion of the inner stick section 4 and includes a stop pawl 34 which projects outwardly through an opening 35 formed in the lower end portion of the inner stick section 4.
  • the locking member 33 has a bent lower end portion which projects outwardly through an upper recess 5 of the handle 5.
  • a button 36 is mounted on the lower end of the locking member 33.
  • FIGS. 9 and 10 The detailed construction of the handle mechanism is shown in FIGS. 9 and 10.
  • 38 is a screw connecting the handle 5 to the lower end of the inner stick section 4.
  • 39 is a locking member mounted in the lower end portion of the inner stick section 4, and 40 is a small opening in the section 4 adapted to receive therein the locking member 39.
  • An auxiliary tubular member 41 which is fitted over the lower end portion of the inner stick section 4 is formed with a guide slot 42 for the locking member 33 for both maintaining the umbrella closed and bringing it to the open state.
  • 44 is an opening formed in the auxiliary tubular member 41 for providing relief for the locking member 39.
  • the auxiliary spiral spring 43 is effective to maintain the umbrella the closed state.
  • the auxiliary spiral spring 43 is also effective to facilitate the umbrella opening operation when the button 36 is depressed to release the stop pawl 34 from the opening 31 and to cause the lower rib supporting member 28 to move upwardly by the biasing forces of the spiral springs 6 and 7.
  • auxiliary spiral spring 43 mounted between the lower end of the auxiliary tubular member 41 formed with the slot 42 for guiding the locking means 33 and the lower end of the inner stick section 4 ensures that the stop pawl 34 and engaging opening 35 are engaged positively and permits the former from being released from the latter smoothly and quickly.
  • the provision of the auxiliary tubular member is effective to compensate for the loss of mechanical strength that might otherwise be caused by the formation of the cutout 35 in the inner stick section 4 through which the locking member sticks out.
  • the first and second spiral springs 6 and 7 differ from each other in their biasing forces. If the spring 6 has a lower biasing force than the spring 7, the locking member 12 will first be released from engagement in the small opening 14 to permit the intermediate stick section 3 to be received in the telescopic sliding motion in the outer stick section 1, and then the locking member 13 will be released from engagement in the small opening 15 to permit the inner stick section 4 to be received in telescopic sliding motion in the intermediate stick section 3. If the spring 7 has a lower biasing force than the spring 6, the locking member 13 will first be released from engagement in the small opening 15 to permit the inner stick section 4 to be received in telescopic sliding motion in the intermediate stick section 3 as shown in FIG.
  • the cylindrical member 29 is moved downwardly by one hand while the handle 5 is held by the other hand.
  • the main rib portions 16 and forward rib portions 17 are moved toward the stick by the supporting ribs 19 and holding ribs 18.
  • the third spiral spring 32 is compressed. Further downward movement of the cylindrical member 29 releases the locking member 13 from engagement in the small openings 15, 15 to permit the major part of the inner stick section 4 to be received in telescopic sliding motion in the intermediate stick section when the spring 6 has a higher biasing force than the spring7.
  • the spring 7 is then compressed and the stop pawl 34 is engaged in the opening 31 of the reduced portion 30 as shown in FIGS. 2 and 9.
  • forward rib portions 17 are gathered together and the handle 5 is pushed upwardly while the umbrella is closed, then the forward rib portions 17 are engaged in the recess 5' of the handle 5 (the forward rib portions 17 are omitted in F I6. 10).
