  • a core rod 32 firmly mounted at one end to the core member, and after having passed through a ring 33 firmly mounted at the lower end of the intermediate shaft member 3, the core rod is firmly connected to a core member 35 which is firmly mounted at the upper end of the lower inner shaft member 4 by way of a pin 34. Therefore, the aforementioned coil spring is actually sitting on the ring 33 and the core member 35 at the opposite ends thereof.
  • a tip portion 36a thereof is engaged into a small opening 1a formed in a wall of the outer shaft member 1 through a corresponding opening of the grip sleeve member.
  • a second latch 38 having a tip portion 38a protruding through an elongated opening 39, the protruded tip portion 38a being adapted to engage into a small opening 1b formed in the wall of the outer shaft member 1 at a portion a little below the small opening 10.
  • the latch 38 is further formed with a push button portion 38b extruded through the elongated opening 39 of the lower inner shaft member 4, while the grip sleeve member 23 is formed with a longitudinal groove 23a framed with protecting wall members 23b to provide a space for housing the push button portion 38b in the umbrella closed condition as shown in FIG. 1 so that the push button portion 38b is not carelessly operated.
  • the grip 9 is provided with a bead ring 40 adapted to be movable for an extent along the axis of the grip 9 so as to selectively engage with and collect the tip portion of the ribs 5 as well as to cover the push button portion 38b.
  • the bead ring 40 In operation, starting from the fully closed condition as shown in solid lines in FIG. 1, the bead ring 40 is first shifted downward, whereby the tip of the ribs 5 are released and take a little opened condition as shown by phantom lines in FIG. 1.
  • the latch 36 is pressed so as to disengage the tip portion 36a from the small opening la of the outer shaft member 1, whereby the anchoring of the grip sleeve member 23 to its lowermost portion is released and the grip sleeve member goes upward under the action of the elastic force exhausted by the compression coil springs 10 and 21 until the grip sleeve member 23 comes to the position as shown in FIG. 2 where the umbrella is fully opened.
  • the coil spring 21 wound around the sleeve 14 will extend, and since the lower end of the coil spring 21 is supported by the ring 20 which is connected with the intermediate inner shaft member 3 by way of the pin 19, the spring force of the coil spring 10 and that of the coil spring 21 act in opposition via the pin 19, and when the two counter forces have balanced, the extension of the coil spring 10 is once held and thereafter the extension force of the coil spring 21 acts mainly to urge the sleeve 14 and the third ring 14a upward along the outer shaft member 1. After the extension force of the coil spring 21 has somewhat weakened, the coil spring 10 will act again to urge the ring 20 upward, and in this manner the coil springs 10 and 21 are interrelatedly extended while extending the shaft of the umbrella.
  • the auxiliary ribs 13 are turned up and the umbrella is opened.

  • the fourth ring 22 and the grip sleeve member 23 are pulled up until they take the positions as shown in FIG. 2.
  • the coil spring 10 Due to the relative extention of the outer shaft member 1 and the lower inner shaft member 4, the coil spring 10 is extended so much that the extention force thereof is reduced almost to zero, and at the same time as the coil spring 10 loses its extention force, the coil spring 21 is also relieved from its counter force, and thus the coil spring 21 extends and loses its extention force.
  • the elastic energy accumulated in the assembly of the spokes 25 starts to act and close the umbrella as the elastic belt members 26 and 27 will resume their straightened shape.
  • the grip sleeve member 23 is lowered until it takes the position as shown in FIG.
  • the shaft in the extended condition as shown in FIG. 3 is contracted by applying compression force at opposite ends of the shaft, i.e., at the tip of the upper inner shaft member 2 and the grip 9, wherein as the compression force is applied, the lower inner shaft member 4 is inserted more deeply into the outer shaft member 1 by compressing the coil springs 10 and 21 until at last the tip portion 38a of the latch 38 engages into the small opening 1b of the outer shaft member 1.
  • the push button portion 38b of the latch 38 is reduced to be a small projection formed with an inclined edge adapted to come in engagement with an upper end of of a sleeve portion 40a of the bead ring 40.
  • the grip 9 is formed with a counterbore 41 at its upper end portion adapted to receive the lower end portion of the sleeve 40a and a coil spring 42 is housed in the counterbore 41 in a manner of being wound around the lower inner shaft member 4 and lightly urge the bead ring 40 upward so that the bead ring 40'is kept in a position to automatically engage with the tips of the ribs but can be easily lowered to release the tips of the ribs when required.
  • the bead ring 40 is pushed upward by fingers so that the upper end of the sleeve 40a slides over the inclined edge of the push button portion 38b by urging the latch 38 to its disengaging position where the tip portion 38b of the latch 38 is disengaged from the small opening 1b of the outer shaft member 1.
  • the sleeve member 23 is formed with a cover portion 23b adapted to cover the push button portion 38b of the latch 38 in the fully closed condition as shown in FIG. 11.
  • a third ring mounted on said shaft below said second ring and pivotably carrying said supporting rods pivotably supporting said extensible rods;
  • a fourth ring mounted on said shaft below said third ring and pivotably carrying at a site other than the pivotal point of each of said extensible rods, said spokes pivotably supporting said ribs;
  • said second ring menas being capable of urging said upper and intermediate shaft members apart with respect to said outer and lower'shaft members;
  • first latch means for opening the umbrella said latch means being capable of disengageably engaging said fourth ring;
  • said second latch means being provided in the lower portion of the lower shaft member and being capable of releasing the outer shaft member from its engagement with the lower shaft member
  • said spokes are constituted by pairs of elastic belt members, each pair being associated with a corresponding one of said ribs, wherein the elastic belt members belong to adjacent pairs are interconnected intermediate the span thereof, whereby, as the umbrella is opened, the ribs of each pair are elastically bowed laterally intermediate the span thereof to store force for aiding collapsing the umbrella;
  • said fourth ring including means housing said second latch means when the umbrella is closed, to prevent accidental finger-release of the second latch means.
  • each individual of said elastic belt members of each pair belonging to each one of said ribs is interconnected with each other individual in the same pair intermediate thespan thereof between the one, outer end thereof which is pivotably connected to said rib and the site where the adjacent pairs are connected with that pair.
