Definitions

  • This invention relates to an automatic foldable umbrella, more particularly to an automatic foldable umbrella which is operable effortlessly.
  • a conventional automatic foldable umbrella as disclosed in U.S. Patent No. 6,684,893 B2 is shown to include a handgrip 1, an operating unit 2, a central shaft unit 3, a central spring 4, a top hub 5, a runner 6, a rib-and-stretcher unit 7, and a cord unit 8.
  • the operating unit 2 has a retained protrusion 202 disposed on a movable ring 201 to be retained in a retaining hole 602 in the runner 6 so as to hold the central shaft unit 3 in a folded position while the central spring 4 is in a compressed state, a spring-biased actuator 203 pivotably mounted on the movable ring 201 to be turnable to disengage from or engage a retained block 801, and a push button 204 manually operable to move the movable ring 201.
  • the central shaft unit 3 includes lower, middle and upper shafts 301, 302, 303 telescopically coupled to one another.
  • the cord unit 8 has a connected end secured to the top hub 5, and extends to be wound on a pulley 601 mounted on the runner 6 and a pulley 501 mounted on the top hub 5 to terminate at an anchoring end that is secured with the retained block 801.
  • the retained block 801 is retained at a retaining region 301' of the lower shaft 301 to hold the cord unit 8 in a tensed state so as to maintain the rib-and-stretcher unit 7 in a spread position when the central shaft unit 3 is moved to an extended position by the biasing action of the central spring 4, as shown in Fig.
  • the central spring 4 since the central spring 4 must be made to have a biasing force sufficient to move the central shaft unit 3, the runner 6, and the rib-and-stretcher unit 7 to open the umbrella, a relatively large manual force is required to compress the central spring 4 for folding the central shaft unit 3, which is inconvenient to the user, especially for a woman or a child, and which may cause injury to the user once the user inadvertently lets the umbrella slips from his/her grasp during folding.
  • An object of the present invention is to provide an automatic foldable umbrella which can be operated easily and effortlessly so as to reduce the risk of the umbrella slipping from a user's grasp during folding.
  • the automatic foldable umbrella includes: a central shaft unit having upper and lower shafts which are telescopically coupled to each other along an axis, and which respectively have top and bottom ends; at least one middle shaft having upper and lower ends which are respectively inserted into and sleeved on the upper and lower shafts; and an inner tube which has an attachment end that is disposed to be moved with one of the upper and middle shafts and which extends downwardly to terminate at an abutment end.
  • the lower shaft has a retaining region.
  • a central spring is disposed in the lower shaft to bias the middle shaft to move relative to the lower shaft from a folded position to an extended position.
  • a top hub is disposed on the top end of the upper shaft.
  • a runner is sleeved on and movable relative to the upper shaft between distal and proximate positions relative to the top hub.
  • a rib-and-stretcher assembly pivotally interconnects the top hub and the runner so as to be moved from a collapsed position to a spread position when the runner is displaced from the distal position to the proximate position.
  • a first force transmitting unit includes: a first direction reversing member disposed on the upper shaft and distal from the top end; a second direction reversing member disposed on the middle shaft adjacent to the upper end; a first cord having a first connected end tensely moved with the top end of the upper shaft, a first cord segment which extends downwardly from the first connected end in the upper shaft to be wound on the first and second direction reversing members, and further downwardly into the inner tube, and which terminates at an anchoring end; and a retained member which is connected with the anchoring end and which is displaceable between retained and released states, where the retained member is retained with and removed from the retaining region, respectively.
  • the first direction reversing member When the middle shaft is biased to move from the folded position to the extended position, and when the retained member is kept in the retained state, the first direction reversing member is pulled up by the first cord segment to move toward the second direction reversing member so as to displace the upper shaft to a stretched-out position.
  • the first direction reversing member When the retained member is displaced to the released states, the first direction reversing member is set free and is allowed to descend, thereby permitting the upper shaft to move downward relative to the middle shaft to a retracted position while the rib-and-stretcher assembly is displaced to the collapsed position.
  • a second force transmitting unit includes: a third direction reversing member disposed on the upper shaft adjacent to the top end, and a second cord having a second connected end tensely moved with the middle shaft, and a second cord segment which extends upwardly from the second connected end to be wound on the third direction reversing member and which is led downwardly to terminate at a third connected end that is connected to the runner.
  • the runner is moved from the distal position to the proximate position when the upper shaft is displaced from the retracted position to the stretched-out position.
  • the upper shaft can be moved downward relative to the middle shaft when the rib-and-stretcher assembly is collapsed, a compression force required to displace the central shaft unit to the folded position is significantly reduced. Hence, the folding operation of the central shaft unit can be conducted in a convenient and effortless manner.
  • the first embodiment of an automatic foldable umbrella is shown to comprise an operating unit 10, a central shaft unit 30, a central spring 40, a top hub 50, a runner 60, a rib-and-stretcher assembly 70, a first force transmitting unit 80, and a second force transmitting unit 90.
  • the operating unit 10 has a mounting shell 11, a spring-biased push button 12 which is manually movable relative to the mounting shell 11 and which has a retaining portion 121, an actuator 13 which is pivota by mounted on the push button 12 and which has an engageable end 131 that is turnable between non-actuatable and actuatable positions, and a torsion spring 14 disposed to bias the actuator 13 to the actuatable position.
  • the central shaft unit 30 includes upper and lower shafts 32, 31 which are telescopically coupled to each other along an axis (L), and which respectively have top and bottom ends 320, 310 that are respectively mounted in the top hub 50 and the mounting shell 11, at least one middle shaft 33 having upper and lower ends 334, 335 which are respectively inserted into and sleeved on the upper and lower shafts 32, 31, and an inner tube 34 which has an attachment end 343 that is secured to the top hub 50 and which extends downwardly to terminate at an abutment end 344 that is not beyond the upper shaft 32 .
  • the retaining portion 121 and the actuator 13 of the operating unit 10 are disposed opposite to each other in terms of the axis (L).
  • the lower shaft 31 has a retaining region 311 adjacent to the bottom end 310, and an abutment region 312 located above the retaining region 311.
  • the upper shaft 32 has an outer passage 321 disposed offset from the axis (L) .
  • the middle shaft 33 has a plug 331 which is disposed in the upper end 334 and which has a through hole 333 that extends along the axis (L) such that the inner tube 34 is slidably fitted through the through hole 333.
  • the inner tube 34 surrounds the axis (L) to define an inner passage 341, and an axial slot 342 configured to communicate the outer passage 321 with the inner passage 341.
  • the central spring 40 is a compression spring 40 which is disposed in the lower shaft 31 and which abuts against the abutment region 312 and the plug 331 to bias the middle shaft 33 to move upwardly relative to the lower shaft 31 from a folded position to an extended position.
  • the runner 60 is sleeved on and movable relative to the upper shaft 32 between distal and proximate positions relative to the top hub 50.
  • the rib-and-stretcher assembly 70 pivotally interconnects the top hub 50 and the runner 60 so as to be moved from a collapsed position to a spread position when the runner 60 is displaced from the distal position to the proximate position.
  • the first force transmitting unit 80 includes a first direction reversing member 83 disposed in the outer passage 321 of the upper shaft 32 and distal from the top end 320, a second direction reversing member 84 disposed on the plug 331 of the middle shaft 33, a first cord 81 having a first connected end 811 which is secured in the outer passage 321 adjacent to the top end 320, a first cord segment 813 which is disposed in the outer passage 321, which extends downwardly from the first connected end 811 to be wound on the first and second direction reversing members 83, 84, and further downwardly through the axial slot 342 into the inner passage 341 of the inner tube 34, and which terminates at an anchoring end 812, and a retained member 82 which is connected with the anchoring end 812.
