Description
- 1. Field of the Invention
- The invention relates to windproof umbrellas and more particularly to a light windproof umbrella.
- 2. Description of Related Art
- Umbrellas are widely used personal articles. It is often that wind will catch an umbrella user unaware and exert a force against an inner surface of a canopy of the umbrella so as to cause the canopy to invert from its normal operable position to an upward convex position.
- Windproof umbrellas are thus developed for windy weather. For example, U.S. Pat. No. 7,980,262 discloses a windproof umbrella comprising a
center post 10 comprising anupper grommet 11, an intermediate fixedring 12, and a lowersliding runner 13; a plurality ofribs 20 each having oneend 21 pivotably secured to thegrommet 11 and anotheropen end 22; a plurality ofmain joints 51 each formed at a portion of therib 20 proximate to theother end 22; a plurality ofstretchers 30 each having oneend 31 pivotably secured to thering 12 and theother end 32 slidably and pivotally secured to themain joint 51; a plurality of auxiliary joints 61 each formed at a portion of thestretcher 30; and a plurality ofstruts 40 each having an oneend 41 pivotably secured to therunner 13 and anotherend 42 moveably secured to the auxiliary joint 61; alower canopy 70 fastened in covering relationship on theribs 20; and anupper canopy 80 having a center secured to thegrommet 11 and an outer peripheral edge positioned over a portion of thelower canopy 70 in covering relationship to all of themain joints 51, wherein wind caught beneath thecanopies canopies upper canopy 80 to lift away from a portion of thelower canopy 70 to form a plurality pairs of communicating inner andouter vent holes 71, 81 with theother ends 32 of thestretchers 30 sliding away from thecenter post 10, each pair of the inner andouter vent holes 71, 81 being defined by the portions of the upper andlower canopies adjacent ribs 20, and the adjacentmain joints 51. - However, a number of drawbacks have been found in the prior art windproof umbrella. In detail, diameters of the
stretchers 30, thestruts 40 and theribs 20 are required to be equal so that the umbrella can withstand the force exerted thereon by strong wind. This inevitably can increase the weight of the umbrella greatly, resulting in a decrease of portability of the umbrella. Further, a person has to exert a great force to grasp thecenter post 10 in windy weather. This can quickly exhaust the strength of the person holding the umbrella. Thus, the need for improvement still exists. - It is therefore one object of the invention to provide a windproof umbrella comprising a center post comprising a top ferrule, an upper grommet, an intermediate sliding ring under the upper grommet, and a sliding runner under the intermediate sliding ring; a plurality of ribs each having one end pivotably secured to the upper grommet and the other end being open; a plurality of main joints each formed at a portion of the rib proximate to the other end of the rib; a plurality of auxiliary joints each formed at a portion of the rib between the main joint and the upper grommet; a plurality of stretchers each having one end pivotably secured to the intermediate sliding ring and the other end moveably secured to the rib; a plurality of struts each having one end pivotably secured to the sliding runner and the other end pivotably secured to the auxiliary joint; a lower canopy fastened in covering relationship to the main joints and portions of the ribs wherein an inner closed edge of the lower canopy is secured to points of the ribs proximate to the auxiliary joints and not covering the auxiliary joints, and an outer peripheral edge thereof is secured to the other ends of the ribs; an upper canopy having a center secured to the upper grommet and an outer peripheral edge positioned over a portion of the inner peripheral edge of the lower canopy and being in covering relationship to the auxiliary joints, wherein wind caught beneath the lower and upper canopies applies pressure to the lower and upper canopies to cause a portion of the upper canopy to lift away from a corresponding portion of the lower canopy to form a plurality of vent holes, slide the other ends of the stretchers toward a direction away from the center post, and slide the intermediate sliding ring downward along the center post.
- The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
-
FIG. 1 is a perspective view of the frame of a light windproof umbrella according to the invention, the umbrella being open and the canopies being shown in phantoms; -
FIG. 2 is a fragmentary view of the umbrella; -
FIG. 3 is an exploded view ofFIG. 2 ; -
FIG. 4 is a side elevation in part section ofFIG. 2 showing the umbrella frame being pushed upward to open; -
FIG. 5 is a view similar toFIG. 4 showing the umbrella frame being pushed downward to close; -
FIG. 6 is a fragmentary view ofFIG. 4 showing a state of the umbrella prior to wind blowing from below; and -
FIG. 7 is a view similar toFIG. 6 showing a state of the umbrella in response to strong wind blowing from below. - Referring to
FIGS. 1 to 7 , a lightwindproof umbrella 1 in accordance with the invention comprises the following components as discussed in detail below. - A
center post 10 comprises atop ferrule 14, anupper grommet 11, an intermediatesliding ring 12 under thegrommet 11, a lowersliding runner 13 under thering 12, and alock 15 adjacent to the slidingmember 13 from below, thelock 15 including an exposedtab 151 adapted to be pressed to unlock thelock 15 for closing theumbrella 1. A plurality ofribs 20 each have oneend 21 pivotably secured to thegrommet 11 and the otheropen end 22. A plurality ofmain joints 51 each are formed at a portion of therib 20 proximate to theother end 22. Themain joint 51 is shaped as a U and comprises a firsttubular end 511 with therib 20 passing through, a secondtubular end 512 also with therib 20 passing through, aU-shaped bar 510 interconnecting the first and secondtubular ends wide channel 513 defined by thebar 510, the first and secondtubular ends rib 20 between the first and secondtubular ends - A plurality of
stretchers 30 each have oneend 31 pivotably secured to thering 12 and theother end 32 shaped as a closed loop and put on thebar 510 of themain joint 51 to be moveably restrained in thechannel 513 with a large moveable extent. A plurality ofauxiliary joints 52 each are formed at an intermediate portion of therib 20 with the increased support of one of a plurality ofstruts 40 to reinforce the whole strength of thewindproof umbrella 1 of the invention. Theauxiliary joint 52 is shaped as a U and comprises a firsttubular end 521 with therib 20 passing through, a secondtubular end 522 with therib 20 passing through, aU-shaped bar 520 interconnecting the first and secondtubular ends narrow tunnel 523 defined by thebar 520, the first and secondtubular ends rib 20 between the first and secondtubular ends struts 40 each have oneend 41 pivotably secured to therunner 13 and theother end 42 shaped as a closed loop and put on thebar 520 to be pivotably restrained in thetunnel 523. - Preferably, the
struts 40 and therib 20 are formed of carbon-fiber-reinforced polymer (CFRP). - Still preferably, the
stretchers 30 are formed of CFRP. A diameter of thestretcher 30 is less than that of therib 20 and thestruts 40, such as one-half of the diameter of therib 20 and thestruts 40. Theelongated stretchers 30 thus have the advantages of being light and strong. - A
lower canopy 70 is fastened in covering relationship to themain joints 51 and portions of theribs 20. In detail, an inner closed edge of thelower canopy 70 is secured to points theribs 20 proximate to but not covering theauxiliary joints 52 and an outer peripheral edge thereof is secured to theother ends 22 of theribs 20. - An
upper canopy 80 has its center secured to thegrommet 11 and its outer peripheral edge positioned over a portion of inner peripheral edge of thelower canopy 70 and being in covering relationship to theauxiliary joints 52. That is, themain joints 51 are covered by theupper canopy 80 so as to form a plurality ofvent holes 71 each being defined by the lower andupper canopies adjacent ribs 20 proximate to themain joints 51. - As shown in
FIGS. 6 and 7 , during rainy, windy weather, wind (as indicated by a plurality of groups of curved arrows ofFIG. 7 ) caught beneath thecanopies umbrella 1 may apply pressure to the undersides of thecanopies upper canopy 80 proximate to themain joints 51 to lift away from the portion of thelower canopy 70 proximate to themain joints 51. As such, a plurality ofvent holes 71 are formed. Also, theother ends 32 of thestretchers 30 slide toward the outer direction as indicated by one hollow arrow proximate to thebar 510 and thesliding ring 12 slides downward along thecenter post 10 as indicated by the other hollow arrow between thesliding ring 12 and thegrommet 11 inFIG. 6 . Therefore, wind passes through thevent holes 71 for escape from theumbrella 1. It is contemplated by the invention that any excessive wind will not invert theumbrella 1 due to the above descriptions and this is the characteristics of the invention. - During rainy, windy weather, wind caught beneath the
canopies umbrella 1 may apply pressure to the undersides of thecanopies upper canopy 80 proximate to themain joints 51 to lift away from each corresponding portion of thelower canopy 70. As discussed above, theother ends 32 of thestretchers 30 are freely and moveably restrained by themain joints 51 in a larger range, theother ends 42 of thestruts 40 are pivotably secured to theauxiliary joints 52, and oneends 41 of thestruts 40 are pivotably secured to therunner 13. Theribs 20 may flexibly bend upward to cause theother ends 32 of thestretchers 30 to slide toward the outer direction (as indicated by arrow inFIG. 7 ). Also, one ends 31 of thestretchers 30 may slide downward along thecenter post 10 to cause theother ends 32 thereof restrained in thechannel 513 to slide toward the outer direction. Further, thestruts 40 may have both ends 41, 42 pivoting about theauxiliary joints 52 and therunner 13. The flexible nature of theribs 20 in cooperation with themoveable ends 32 of thestretchers 30 at themain joints 51 and thesliding ends 31 of thestretchers 30, and the pivotal connections of thestruts 40 to both theauxiliary joints 52 and therunner 13 can prevent theumbrella 1 from being inverted when strong wind blows. - The moveably restrained
other ends 32 of thestretchers 30 in themain joints 51 is the first force connecting thestretchers 30 to theribs 20 and this can achieve an increased flexible adjustment of theribs 20. Further, thechannels 513 of themain joints 51 can provide a large extent of the flexible deformation of theribs 20 and thus increase the resistance of theribs 20 against excessive wind. The above characteristics of thestretchers 30 are carried out by cooperating with thesliding ends 31 thereof. The pivotal fastening of theother ends 42 of thestruts 40 at theauxiliary joints 52 is the second force connecting thestruts 40 to theribs 20. Theribs 20 may bend upward to pull the overlap of thecanopies vent holes 71. Advantageously, excessive wind may escape via thevent holes 71. This is the flexible deformation characteristic of theumbrella 1 for resisting inversion from excessive wind. Theumbrella 1 may return to its original shape when excessive wind is successfully vented. This wind escape characteristic of thewindproof umbrella 1 with an aid of the reinforced configuration in a larger movable range of themain joints 51 and theauxiliary joints 52, together with the first force connecting thestretchers 30 to theribs 20 and the second force connecting thestruts 40 to theribs 20, is unique and novel and can be effectively resistant to inversion from the excessive wind. - While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
