1. Field of the Invention
The present invention relates generally to the field of umbrellas and more specifically relates to an improved multi-functional umbrella comprising a mister having a variably controllable and pivotal mist head.
2. Description of the Related Art
Umbrellas are a handy and useful tool for protecting a user from getting wet from rain and precipitation, and for shielding a user from harmful rays emanating from the sun. People frequently carry with them an umbrella to be used in case of rain or on hot and sunny days. Since umbrellas are very commonplace in different societies, some people like to accessorize by carrying with them a fashionable or stylish umbrella. Alternatively, some people like to use umbrellas that provide other functions in addition to sun blocking and precipitation (rain) protection. Umbrellas may also have a variety of uses. Parasols are often used by beach goers and are planted in the sand to provide protection from the sun while sun bathing. Alternatively, many home owners enjoy sitting outside during the daytime and setting up a large umbrella to cover patio table or lawn chairs. There are virtually limitless uses for conventional umbrellas.
Many prior art umbrellas suffer from lack of durability. The elements of the weather as well as mechanical use or overuse have made existing umbrellas usable for only short periods of time. For example, problems with umbrella inversion, rusting of the frame, ripping of the material with strong gusts of wind, traction and retraction of the metal parts have reduced the longevity of the average umbrella. The embodiments described herein aim to provide a multi-functional and multi-purpose umbrella with increased durability thus allowing owners to enjoy the use of the umbrella longer than what is typical for an umbrella. It is also desirable to provide an umbrella that is aesthetically pleasing which the conventional versions do not. Exposure to the environment may lead to skin cancers, diseases associated with skin discoloration, blistering, pain which may be unpleasant for many suffers. It is desirable that exposure be minimized to avoid these health risks.
Various attempts have been made to solve the above-mentioned problems such as those found in U.S. Pat. No. 6,886,759 to Okronick; U.S. Pat. No. 5,421,354 to Bolton; U.S. Pat. No. 6,682,000 to Apple; U.S. Pat. No. 7,497,225 to Klein, Jr.; U.S. Pat. No. 7,104,270 to Peter Dong; U.S. Pat. No. 5,143,107 to Jean M. Kelley; and U.S. Pub. Nos. 2008/0179426 to Johnson; 2005/0161066 to Joen-Shen Ma; 2002/0078985 to Fariss Farr; and 2008/0048051 to Chang. This prior art is representative of multi-functional umbrellas. None of the above inventions and patents, taken either singly or in combination, is seen to describe the invention as claimed.
Ideally, a mister-equipped umbrella should provide a user with an easy to open, easy to close (user-friendly), durable umbrella equipped with a mister assembly and, yet would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable mister-equipped umbrella system to enable a user to variably select a misting function to receive a steady supply of mist while being protected from the rays of the sun via an umbrella canopy and to avoid the above-mentioned problems.
In view of the foregoing disadvantages inherent in the known umbrella art, the present invention provides a novel mister-equipped umbrella system. The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a novel and durable umbrella comprising a mister assembly, an ergonomic handle, and possessing other unique characteristics for providing a user with optimal protection from all forms of precipitation and from harmful ultraviolet sun rays. Further, the present invention comprises an aesthetically appealing umbrella that may or may not be solar-powered.
A mister-equipped umbrella system as disclosed herein, in a preferred embodiment, comprising an umbrella assembly having an umbrella shaft, a tube, a runner, a plurality of stretchers, a plurality of ribs each terminating in a tip, a cover comprising at least one UV coating, a handle (having an inner volume for storing batteries and an outer surface for gripping), a fluid reservoir, a pump, a tube, and at least one mister. The umbrella shaft, the tube, the runner, the stretchers, the plurality of ribs, the cover, and the handle in combination form a collapsible umbrella assembly. Further, the umbrella shaft, the tube, the runner, the cover, and the plurality of ribs of the umbrella assembly are deployable from a closed-collected condition to an open condition to shield a user from at least one ambient environmental condition.
The mister in preferred embodiments may be mounted to the tube and the tube may serve to provide fluid communication between the fluid reservoir and the mister. The mister may be battery-powered via the batteries, or alternatively may draw power from a solar power source. The mister is designed to provide an atomized-mist (water—preferably deionized water, reverse osmosis water, to prevent calcium or mineral build up on and in the various components) pumped from the fluid reservoir via the pump, whereby the pump may be powered via the batteries or via the solar powering means. The mister in combination with the umbrella assembly of the mister-equipped umbrella system provides moisture about (on or around) the user to dissipate heat in a hot ambient environmental condition. The UV coating on the cover of the umbrella assembly may further protect the user by shielding him/her from UV rays, thereby promoting a healthy lifestyle in its users.
The user may deploy the collapsible umbrella assembly between a closed condition and an open condition in a conventional umbrella-opening manner by sliding a runner from a down-position to an up-position. Once the runner is manipulated into an up-position, the runner may lock into place via a first locking mechanism. The runner may be connected to a distal end of the plurality of ribs. The sliding motion opens up the cover by extending ribs of the cover outwardly. The collapsible umbrella assembly may be manipulated from an open condition to a closed condition by squeezing in the first locking mechanism and moving the runner from an up-position to a down-position. Once the runner has been manipulated into a down-position it may lock into place via a second locking mechanism. Squeezing the fastener again on the runner may allow for the movement of the runner from a down-position to an upward position. The various parts preferably comprise anti corrosive metal such as aluminum or the like (or non-metal such as plastic or the like) and may also further comprise a lining having an anti rust coating.
The mister-equipped umbrella further comprises a mister assembly, as previously indicated. The mister assembly generally comprises a fluid reservoir, a pump, a tube, and a mister head. The fluid reservoir comprises a canister for storing fluid, such as water which may comprise insulation means. The pump delivers the fluid via the tube to the mister head. In a preferred embodiment, the mister head comprises more than one misting option. For example, mister head comprises options for delivering a single spritz or an incremental (or non-incremental) mist spray. In use, the user may select one of the misting options via operating buttons on a handle of the umbrella.
Push button (operating buttons) may comprise hardened materials: rubber, plastic, silicon base, petroleum-based, plastic, or metal or combination thereof. The operating button(s) may be manually a) pressed once, twice, or multiple times; b) depress until mist is dispensed, depress to spray, depress to stop spray; c) may be black in color, multicolored, white in color, or clear; d) shape may be circular, octagonal, hexagonal, semicircular, linear, geometric or free form; e) placement may be on handle or along stem of the umbrella. The preferred button(s) used may be manually or electrically operated such as those knowledgeable in the art would readily appreciate use thereof. Rheostat-style buttons may be used to control the volume of fluid that may be dispensed.
By way of example the following button may be employed for use with the present invention: a pushbutton switch (a two-position device actuated with a button that is pressed and released). The pushbutton switch used herein preferably has an internal spring mechanism returning the button to its “out,” or “unpressed,” position, for momentary operation. Alternate pushbutton switches that may be used will latch alternately on or off with every push of the button. Other embodiments may use pushbutton switches which will stay in their “in,” or “pressed,” position until the button is pulled back out. The pushbutton switch may have a mushroom-shaped button for easy push-pull action. Buttons as described above are purely intended for enablement purposes and are not to be considered in any way limiting to the buttons that may be used. Selector switches may be used and when used may be actuated with a rotary knob or lever to select one of two or more positions. Selector switch when used can either rest in any of their positions or contain spring-return mechanisms for momentary operation.
The button(s) used may be manual or electrically operated as mentioned. On electric versions the button may be manipulated by being pressed and/or depressed, battery/batteries which may be used for activation may comprise AA, AAA, D, C. Batteries may comprise Lithium Ion versions, solar energy rechargeable batteries; batteries send a signal to the pump to activate or deactivate to cause water to flow or to not flow. Amount of water flowing may be regulated. Water/fluid is pushed or pulled into tubing/pipes located from the reservoir into tubing along the stem of the umbrella where it is dispensed into the mister where the water is concentrated into a fine mist and is dispensed to provide cooling for the user. The rotational mister may be used to change the angle of dispensed water as well as direction of the mist. Diameter of tubing can range from a few millimeters to a centimeter or under a centimeter. Length of the tubing ranges from a few inches up to under 50″. The tubing may be one-piece or connected through one or more joints. If connected through joints tubing diameter may change. Joints may be flexible or inflexible and made out of the same materials as the flexible tubing, hoses, or plastic, PVC, or ABS pipes. Tubing is preferably durable to withstand extreme temperatures and will not melt or crack under normal ambient conditions. The button is pressed and the water travels in the tube then water is dispensed via the tubing it travels through.
Types of tubing may comprise flexible rubber tubing, flexible plastic tubing, flexible silicon-based hoses: nylon, polyurethane, polyethylene, rubber, plastic, PTFE, PVC, silicon-based pipes or ABS pipes. Tubing is in communication with the buttons and mister such that water can be transported as needed. Those with ordinary skill in the art will now appreciate that upon reading this specification and by their understanding the art of operating buttons, tubing as described herein, methods of manufacturing and using will be understood by those knowledgeable in such art.
The mister may be manipulated to spray in various patterns and in various quantities. In another embodiment, the mister-equipped umbrella may comprise an integrated cooler for cooling the fluid. In such a manner, the user may enjoy a steady supply of cool mist on a hot and sunny day.
In a preferred embodiment the umbrella handle functions as the battery holder as well as a means to hold and manipulate the umbrella. As such, the handle may be constructed from a rigid plastic such as ABS, and will be formed internally to support 2 to 4 AA size batteries. The handle will also have means for the user to access the batteries for replacement, and means to make electrical connection between the batteries and the switch and motor components. The batteries may be standard AA size alkaline batteries, and may comprise of 2 or 4 individual cells connected electrically in series.
Means to connect the cells in series is a function of the internal molding and contact wiring of the handle. The push button switch may be a custom construction or may be purchased, and will make electrical connection when pressed, typically designated as a normally open design. When the push button is depressed, the electrical circuit is closed and current will flow, energizing the electric pump motor. The pump mechanism comprises a motor to provide mechanical power and the pump mechanism to generate pressure on the water. The motor may be purchased from a vendor and implemented as a gear motor or may be direct drive. Gear reduction is necessary to provide high torque low speed required by the pump mechanism. The rotational motor output is applied to a mechanical arm, rack and pinion, or other mechanism for conversion of rotational movement to reciprocal movement necessary for the action of the pump.
Referring now to the water pump, it comprises a piston style pump similar to a hand held spray bottle. Pump action requires the plunger or piston to have sufficient force applied to generate adequate water pressure. The pump mechanism comprises a piston in a cylinder along with one or more check valves. The piston travels back and forth in its cylinder, being pushed and pulled in the cylinder by the motor mechanism, causing water to be pulled into and pushed out of the space inside the cylinder cavity. The check valve functions to direct the water flow from the cylinder cavity to the nozzle at the top of the umbrella when the piston is pushed into the cylinder, and water is drawn into the cylinder cavity when the piston is pulled out in the cylinder. The check valve may be a ball style check valve or flapper style check valve.
Water is drawn from the reservoir into the pump through a filter to prevent debris from entering the pump and possibly clogging the spray function. Water is supplied under pressure to the misting nozzle through a small diameter rigid tube.
The misting nozzle may be positioned towards the top of the umbrella shaft, and may include a swivel or other adjustable connection allowing the user to manipulate the direction in which misting occurs. The rigid tubing that supplies the misting nozzle with water may be routed inside of the fixed length (not telescoping) umbrella shaft, exiting the shaft at the top.
The handle may be injection molded ABS or other similar rigid thermoplastic, constructed to hold 2 or 4 AA cells with means to make electrical connections between the cells and connection to the motor and push button switch.
Push button switch may be constructed out of plastic and conductive non-ferrous metal or plated metals that accept solder connections for the electrical connection. The switch may be custom molded and stamped components, or may be purchased as a drop-in component from a number of vendors. Examples of drop-in switches may include the following: Mfg: Mountain Switch; PN: 104-0013-EVX Mfg: C&K Components; PN: 8532MZQE2.
The motor may be a gear reduction motor such as the following: Vendor: ServoCity; PN: 638256 or may be a direct drive motor such as the following: Mfg: Shenzhen A-OK Motor Co., Ltd. PN: FF-360SH-3840
Water reservoir is a custom designed 4 oz to 8 oz plastic bottle with a screw on cap made of high density polyethylene or similar molded plastic.
Small diameter rigid tube delivering water to the nozzle may be made of high density polyethylene or similar plastic, and may have inside diameter of 2 mm to 3 mm, and length of 40 mm to 60 mm.
Certain embodiments may comprise a digital clock with or without an illuminating means such that time may be displayed. A calendar may also be incorporated. A digital interval time indicator/interval selector/timer can allow the individual to select the time interval to which the mister is activated for mist dispensing. This timer may have the ability to digitally display the countdown till mist dispensing. The indicator/interval selector/timer may be powered by a separate battery and or solar panel or solar film.
The umbrella of the present invention may also comprise inversion prevention. Each canopy layer of the spiraled umbrella preferably overlaps and extends outwardly far enough to prevent rain from entering during a strong gust of wind when present. This mechanism along with a combination mesh/flap assembly located concentrically along the spiraled gaps provides support to the umbrella frame and serves to prevent inversion episodes during a windy environment. The flaps may be flat during normal conditions, but to prevent umbrella inversion may expand to allow optimal airflow of air trapped inside of the umbrella canopy. The flaps may connect the upper layer of the umbrella canopy to the middle layer. The lower flap may connect the middle layer of the umbrella to the lower layer of the canopy. The flaps are expandable in strong gusts of wind and expand in order to allow the trapped air inside the umbrella to escape. The stitching of the flaps allows the flaps to function in this way. The flaps may be stitched in one direction for the upper vent. The middle vent may be stitched in the opposing direction for added strength. The lower vent may be stitched in the same direction as the upper vent. This stitching may allow for the canopy to add strength to the umbrella frame and prevents the canopy from separating from the umbrella frame in sheer load. There may be 1, 2, or 3 vents, as desired by the manufacturer. The sun sensitive color change material may be stitched above and below the vents in a spiral fashion to add elegance.
The present invention holds significant improvements and serves as a mister-equipped umbrella system. For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein.

Further, it should be appreciated that cover 130 of mister-equipped umbrella 102 may comprise UV coating 320, as shown in
In an embodiment of mister-equipped umbrella 102, cover 130 may comprise photochromic material sensitive to sunlight intensity. In such a manner, the photochromic material may enable cover 130 to be temperature sensitive and allow for color changes and design appearance to change based on outdoor temperatures a novel and appealing feature for umbrella users. When sunlight or ultraviolet (UV) radiation is applied to cover 130, the dye becomes excited and the molecular structure is changed allowing a specific color to appear. For example, when UV rays 162 strikes cover 130, cover 130 may change to the color yellow (Asian yellow), an especially desirable color to oriental persons, persons whom also have an affinity to use of umbrellas, but who do not prefer black since it is dull and may hold negative cultural significance as a color. This photochromic material may be stitched in certain locations on the canopy (cover 130) (such as in a spiral direction) or may cover the entire canopy with one or more color changing photochromic colors.
When the stimulus from UV rays 162 is removed, the dye will return to a state of rest, which is its colorless form such that it may return to a specified initial (unexcited condition) color such as green (or other preferred color) for example. In addition, cover 130 comprising photochromic material may allow individuals to have standard designs or allow user(s) 140 to add personal designs to mister-equipped umbrella 102. It should be appreciated that photochromic material of cover 130 may turn a variety of colors according to a limited color spectrum based upon preference of user 140.
