Description
- 1. Field of the Invention
- The present invention generally relates to the field of large-sized sun-shading umbrellas and in particular to an umbrella incorporating a cooling device that generates and sprays mists into a space under of a canopy of the umbrella for cooling the space under the canopy.
- 2. The Related Art
- A large-sized sun-shading umbrella, such as a garden umbrella and a beach umbrella, is often fixed on a heavy base or fit into a center hole defined in a table surface, or pierced into the ground to hold the umbrella in an upright configuration. The umbrella has a canopy that can be opened to provide a sun-shaded surface of large area.
- However, in case of intense sun light, together with dry atmosphere, the canopy of the umbrella, although effective in shielding the intense sun light, is not able to eliminate the hot and dry feeling of a person staying in the space under the canopy. This is often observed in beach umbrellas or even garden umbrellas.
- Thus, the present invention is aimed to provide a cooling device for an umbrella to eliminate the hot and drying feeling of a person staying under the canopy.
- Thus, a primary objective of the present invention is to provide an umbrella comprising a cooling device for overcoming the “hot” feeling of a person staying under a canopy of the umbrella.
- Another object of the present invention is to provide an umbrella having a cooling device of simple structure, which emits mists to lower down surrounding temperature under the umbrella canopy.
- To achieve the above objectives, in accordance with the present invention, there is provided a cooling device adapted to combine an umbrella. The umbrella includes an upright central post along which a runner is movable. A crown is mounted to an upper end of the central post. A plurality of ribs is pivoted to and radially extending from the crown and each rib is linked to and driven by a stretcher having opposite ends pivoted to the runner and the rib respectively. A canopy is attached to and supported by the ribs whereby when the runner moves upward/downward along the central post, the canopy is selectively opened/closed. The cooling device is fixed to and movable with the runner along the central post and comprises a casing fit over and movable along the central post. The cooling device defines an interior space forming a water container containing an amount of water and accommodating a mist generator receiving water from the water container and generating mist. Tubes convey the mist to outlet nozzles that are formed in the casing to direct the mist to a space under the canopy for cooling purposes.
- The present invention will be apparent to those skilled in the art by reading the following description of a preferred embodiment thereof, with reference to the attached drawings, in which:
-
FIG. 1 is a perspective view of an umbrella constructed in accordance with the present invention with a canopy inclined; -
FIG. 2 is an enlarged view of a portion of the umbrella taken from a different perspective; -
FIG. 3 is a side elevational view of the umbrella, with a portion of a post and the canopy being omitted for clarity and simplification; -
FIG. 4 is a cross-sectional view of a cooling device incorporated in the umbrella in accordance with the present invention; and -
FIG. 5 is a side elevational view of the umbrella particularly showing extension of a power cord through the umbrella for supplying power to a mist generator of the cooling device. - With reference to the drawings and in particular to
FIGS. 1 and 3 , an umbrella constructed in accordance with the present invention comprises an umbrella frame comprised of acentral post 10, apivot joint 11 rotatably connecting a lower end of a top extension (not labeled) to an upper end of thecentral post 10, arunner 12 slidable along thecentral post 10, acrown 13 mounted to an upper end of the top extension of thecentral post 10, a plurality ofribs 15 each having an inner end pivoted to thecrown 13 and radially extending from thecrown 13 to support acanopy 16, and astretcher 14 having opposite ends pivoted to therunner 12 and substantially a middle portion of eachrib 15 whereby the movement of therunner 12 along thecentral post 10 in upward/downward direction causes thestretchers 14 to drive theribs 15 upwards/downwards thereby selectively opening/closing thecanopy 16. Thepivot joint 11 allows the top extension and thus thecrown 13 to be selectively orientated at different angle with respect to thepost 10 for shielding sun light from different directions. Preferably, a lower end of thecentral post 10 is fixed to and supported by aheavy base 19. - The opening/closing can be manipulated by means of an opening/
closing device 18 mounted to thepost 10. The opening/closing device 18 comprises acrank 17 that drives a reel (not shown) to pull and release a cable that is coupled to therunner 12 thereby causing therunner 12 to move along thepost 10. This is generally known and thus no further detail is needed herein. - Also referring to
FIGS. 1 and 4 , the umbrella of the present invention comprises a cooling device, generally designated withreference numeral 20, mounted to a lower end of therunner 12 and movable wit therunner 12 in opening/closing thecanopy 16. Thecooling device 20 comprises aconic casing 21 having a reduced upper end fixed to the lower end of therunner 12. Theconic casing 21 encompasses and is slidable along thecentral post 10. Thecasing 21 defines a hollow interior that forms awater container 22. Thecasing 21 also accommodates, at a lower portion thereof, amist generator 25 that receives water from thewater container 22 and generates water mist. Thecooling device 20 further comprises a plurality oftubes 26, serving as mist passages extending from themist generator 25 to an outer circumference of thecasing 21 and communicatingmist outlets 27 formed on and preferably equally spaced along the circumferential wall of thecasing 21 for conveying the mist outside thecasing 21 and into a space under thecanopy 16. - The
water container 22 comprises awater inlet 23, preferably selectively closed by a removable cap (not labeled). Thewater inlet 23 extends beyond thecasing 21 for replenishment of water into thewater container 22. A water level indicator 24 (best seen inFIGS. 2 and 3 ) is provided and can be observed outside thecasing 21 for visual inspection of the amount of water residual in thewater container 22 after operations. - The
mist generator 25 comprises an electrically driven device (not shown) that is powered by an external power source. Apower cord 28 is connected to themist generator 25 by a power switch 29 and forms a plug at a distal end thereof for selective connection with the external power source, such as a wall outlet of an electric main. The power switch 29 allows for selective transmission/supply of electrical power received from the plug to themist generator 25. Themist generator 25 is constructed to receive water from thewater container 22 and driven by the electrical power from thecord 28 to generate and supply atomized water in the form of mist through thetubes 26 to themist outlets 27. Themist outlets 27 spray the mist outwards. - Also referring to
FIG. 5 , thecord 28 extends through an interior channel defined along thecentral post 10 to thecrown 13 and then extends along one of theribs 15 and theassociated stretcher 14 to therunner 12 and then to themist generator 25. - In practice, when an operator rotates the
crank arm 17 to operate the opening/closing device 18 for opening the umbrella, therunner 12 moves toward thecrown 13 along thecentral post 10 to expand thecanopy 16. Once thecanopy 16 is expanded, electrical power is selectively supplied to themist generator 25 via the switch 29 and thecord 28. The mist generated by themist generator 25 is supplied to themist outlet 27 that is configured to direct and distribute the mist into the atmosphere under thecanopy 16. Continuously spraying mist into the space under thecanopy 16 effectively lowers down the temperature of the air under thecanopy 16 and makes the space under thecanopy 16 cooled and comfortable. The mist can be stopped by simply switched off the power supply by the switch 29. - To close the umbrella, the operator simply rotates the
crank arm 17 is a reversed direction, which lowers down therunner 12 along thecentral post 10 thereby collapsing thecanopy 16. Thecooling device 20 moves downward with therunner 12 and eventually stops at the lower portion of thecentral post 10, which leaves the packing and storage of the umbrella unaffected. - Although the present invention has been described with reference to the preferred embodiment thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
