Description
- This invention relates to an umbrella, more particularly to a safety umbrella with an operating sleeve operable to move a runner between upper and lower positions.
- A conventional umbrella, such as that disclosed in
U.S. Patent No. 5,964,235 , includes a runner slidably sleeved on a central shaft to spread and collapse a rib-and-stretcher assembly to which a canopy is fastened. A resilient tongue extends from a ferrule secured on an upper end of the central shaft, and has a distal hook end biased away from the central shaft to be retained in a slot in the runner when the runner is moved upwardly for spreading the canopy. However, when a user presses the distal hook end for downward movement of the runner, the user's finger may get hurt, especially for children. - Moreover, wire ends of a fastening wire wound on the ferrule for pivotally connecting the ribs to the ferrule, and wire ends of a fastening wire wound on the runner for pivotally connecting the stretchers to the runner expose may prick the canopy and the user' s hand and finger during opening or closing of the umbrella.
- An object of the present invention is to provide an umbrella which can be operated safely to spread and collapse a canopy, and which has a simple and rigid structure.
- According to this invention, the umbrella includes a central shaft extending in a direction of an axis, a top notch member fixed on an upper end of the central shaft and including a notched wheel, a rib assembly pivotally connected to the notched wheel for mounting a canopy thereon, a runner sleeved on and movable relative to the central shaft between upper and lower positions and including a notch disc, an operating sleeve, and a stretcher assembly pivotally connected to the notched disc and the rib assembly so as to stretch or retract the rib assembly when the runner is moved to the upper position or the lower position.
- The top notch member includes an upper shell which extends from the notched wheel and which has a smaller dimension than that of the notched wheel, and a resilient tongue which has a tongue body that extends downwardly from the upper shell and that terminates at a hook end. The hook end extends radially to cooperate with the tongue body to form an actuated shoulder surface that faces upwardly. The notched disc has a surrounding passage which surrounds the axis and which is configured for exposing two twisted ends of a lower wire ring. The runner includes a lower shell which extends from the notched disc, which has a smaller dimension than that of the notched disc, and which has a slot that is disposed adjacent to the notched disc and that extends radially therethrough. The slot is configured to permit the hook end to be retainingly engaged therein immediately after an upward movement of the runner to the upper position by thrusting the hook end into the runner against its biasing action.
- The operating sleeve has an inner sleeve surface which surrounds and is axially movable relative to the lower shell. The operating sleeve includes an actuating friction block which is disposed on the inner sleeve surface and adjacent to the slot. The actuating friction block has an actuating friction surface which is configured to face downwardly and to be matingly engaged with the actuated shoulder surface when the hooked end is retained in the slot at the upper position. When the operating sleeve is moved axially away from the upper position, the actuated shoulder surface is pressed by the actuating friction surface to withdraw the hook end inwardly and radially so as to disengage the hook end from the slot, thereby allowing the runner to move toward the lower position. The operating sleeve has a shielding tab which extends upwardly and which is disposed radially and outwardly of the notched disc so as to shield the twisted ends of the lower wire ring.
- By virtue of the operating sleeve and the shielding tab, the umbrella can be operated safely and conveniently without running any risk of injury to the user and the canopy during operation.

Thehook end 223 extends radially to cooperate with thetongue body 221 to form an actuatedshoulder surface 224 that faces upwardly. Aramp 225 is disposed on the actuatedshoulder surface 224, and is inclined from thehook end 223 toward thetongue body 221. Thenotched wheel 21 has a plurality ofupper notches 215 formed in an outer surrounding surface 214 thereof and angularly displaced from one another about the axis (L), and a surroundinggroove 216 surrounding the axis (L) and communicated with theupper notches 215 for receiving anupper wire ring 71 that engages arib assembly 61 to be pivotally connected to thenotched wheel 21 for mounting the canopy thereon. Specifically, thetop notch member 20 has anupper shielding cavity 213 which is disposed on theupper shell 23 and adjacent to thenotched wheel 21 for accommodating two twisted wire ends of theupper wire ring 71 exposed from the surroundinggroove 216, thereby preventing prick injury to a user and the canopy. - The
runner fastener 30 includes arunner 40 and anoperating sleeve 50. - The
runner 40 includes anotched disc 41 and alower shell 42 which extends from thenotched disc 41 and which has a smaller dimension than that of thenotched disc 41. With reference toFig. 2 , thenotched disc 41 has a plurality oflower notches 412 formed in an outer surroundingsurface 411 thereof and angularly displaced from one another about the axis (L), and a surroundingpassage 413 surrounding the axis (L) and communicated with thelower notches 412 for receiving a lower wire ring 72 (seeFigs. 4 and5 ) that engages astretcher assembly 62 to be pivotally connected to thenotched disc 41. Thestretcher assembly 62 is pivotally connected to therib assembly 61 so as to stretch or retract therib assembly 61 when therunner fastener 30 is moved to the upper position or the lower position. The notcheddisc 41 has aninner guideway 44 which extends axially to permit insertion of thetongue body 221 thereinto. Thelower shell 42 has aslot 43 which is disposed adjacent to the notcheddisc 41 and communicating with theinner guideway 44. Theslot 43 extends radially through thelower shell 42 to permit thehook end 223 to be retainingly engaged therein immediately after an upwardmovement of therunner 40 to the upper position by thrusting thehook end 223 into therunner 40 against its biasing action. In particular, theslot 43 has a larger width in a circumferential direction than that of theinner guideway 44 so as to form a pair of retaining stays 431 (seeFig. 2 ) therebetween. Further, therunner 40 has aflange 422 extending radially and outwardly from a lower end of thelower shell 42 to define anabutment shoulder surface 423 facing upwardly, and an axially extendingkey 424 disposed on theflange 422. - With reference to
Fig. 3 , theoperating sleeve 50 includes asleeve body 51 which has aninner sleeve surface 511 surrounding and axially movable relative to thelower shell 42, an actuatingfriction block 52 which is disposed on theinner sleeve surface 511 and adjacent to theslot 43, and ashielding tab 53 which extends upwardly from thesleeve body 51. The actuatingfriction block 52 has an actuatingfriction surface 521 which is inclined and faces downwardly to be matingly engaged with theramp 225 of the actuatedshoulder surface 224 when thehooked end 223 is retained in theslot 43 at the upper position (as shown inFig. 4 ). The innersleeve wall surface 511 has a small-diameter surface region 513 which is fittingly sleeved on and slidably movable relative to thelower shell 42, and a large-diameter surface region 514 which extends downwardly from the small-diameter surface region 513 to define a surroundingabutting surface 516. An axially extendingkeyway 515 is formed in the innersleeve wall surface 511 to be engaged with thekey 424 to serve as a key-and-keyway structure so as to guide axial movement of theoperating sleeve 50 relative to thelower shell 42. -
Figs. 4 and5 illustrate therunner fastener 30 in the upper position, i.e., in an opened state. In this state, thetongue body 221 is received in theinner guideway 44 and thehook end 223 is retained in theslot 43 to have the actuatedshoulder surface 224 abutting against the retaining stays 431 (seeFig. 2 ) so as to retain therunner fastener 30 to thetop notch member 20, thereby holding the umbrella in the opened state. By means of the engagement of thekey 424 and thekeyway 515, angular displacement of theoperating sleeve 50 relative to therunner 40 is prevented such that theramp 225 can confront and be in slidable frictional engagement with the actuatingfriction surface 521. - Referring to
Fig. 6 , when it is desired to close the umbrella, theoperating sleeve 50 is moved axially and downwardly. By means of the friction engagement of the actuatingfriction surface 521 with theramp 225, the actuatingfriction block 52 can readilypress the actuatedshoulder surface 224 to withdraw thehook end 223 inwardly and radially so as to disengage thehook end 223 from theslot 43, thereby allowing the runner fastener 30 to move toward the lower position. As shown inFig. 7 , due to the surroundingabutting surface 516 which is brought to abut against theabutment shoulder surface 423, therunner 40 is moved downwardly with theoperating sleeve 50 to the lower position while preventing theoperating sleeve 50 from slipping from therunner 40. - When it is desired to open the umbrella, by pressing the
operating sleeve 50 upwardly, thetongue body 221 is inserted into theinner guideway 44 from thehook end 223. Thehook end 223 is thrust inwardly against its biasing action and subsequently is retained in theslot 43 when the runner fastener 30 reaches the upper position. - As illustrated, by virtue of the
operating sleeve 50, operation of the umbrella of this invention is safe and convenient. Theshielding tab 53 is disposed radially and outwardly of the notcheddisc 41 so as to shield the twisted wire ends of thelower wire ring 72, and theupper shielding cavity 213 can accommodate the twisted wire ends of theupper wire ring 71. Hence, the umbrella can be operated safely and conveniently without any risk of injury to the user and the canopy during operation.
