Abstract
A fashionable life saving device utilizes the look of casual clothing such as shorts, pants, bathing suits or skorts to disguise inflatable chambers, a gas canister and safety devices including a manual inflation tube, thereby providing a subtle way to ensure safety in and around the water. When inflated, the chambers rest under the users arms, but are safely attached to his waist or the lower part of his body for security and safety.
Description




BACKGROUND OF THE INVENTION




The present invention relates to the field of inflatable safety devices that may be worn by men and women with or as articles of clothing, and more particularly to a flotation device that may be manually activated to release an inflatable element which is designed to rest around the torso and under the arms of the user when inflated while remaining anchored at the waist.




There are many devices known in the art for use in the water that provide flotational assistance to the user. A large proportion of personal flotational devices in use today are designed to be separate from a person's bathing suit. Some are made of bulky flotational materials, while others must be inflated by one's breath or by an external pump. Still others incorporate compressed air canisters. Many of these devices, while providing a large amount of flotational support, are bulky and too unwieldy to carry while performing basic tasks or engaging in water sports.




Many people die each year by drowning. In 1997 alone, more than 4,050 people drowned in the United States. Drowning may be caused by cramps or by exhaustion. Exhaustion can be brought about by swimming too long or far or by performing other activities that cause exhaustion. Other deaths occur when people are caught in rip tides or are involved in boating accidents. The common factor in all of these is the inability of a person to keep their face above water. While people may know of the risk of drowning, many do not take flotational devices with them that may keep them afloat before they enter the water or begin activities near the water.




U.S. Pat. No. 3,935,608, to Freedman et al. (the “'608 patent”), is directed to an article of clothing having a pocket portion containing an inflatable envelope and a compressed fluid container for inflating the envelope whereby, upon inflation, the envelope is forced out of the pocket portion and serves to provide flotational support to the user. The compressed fluid canister of the '608 patent is located at the user's back. See

FIGS. 2 and 3

. There is a means on the fluid container for actuation to release the fluid therefrom and inflate the envelope. See Claim


1


.




The device of '608 patent has several disadvantages. First, the location of the fluid canister of the device is unwieldy; users may not have the time or presence of mind in an emergency situation to reach behind themselves and activate a buoyancy device. Secondly, the envelope of the device “may be deflated by simply unscrewing the screw from the insert.” Col. 2, L. 13-14. Given that the invention of the '608 patent is designed to be worn as an article of clothing and generally only activated during times of emergency, it may be worn frequently or for long periods of time without being activated. Further, it may be moved, dropped or jostled. The invention of the '608 patent will probably also experience vibrations from a car or boat motor. All of these could serve to loosen the screw which is the seal between the air inside the envelope and the environment. As such, there is a substantial risk that the invention may fail when called upon to provide flotational support during an emergency. Further, since the user has access to the screw, human error in replacing the screw may cause a malfunction during an emergency.




U.S. Pat. No. 5,954,556, to Powers, (the “'556” patent), is directed to an inflatable life saving belt comprising a gas source that is linked to reusable inflatable bags at multiple locations on the belt. The gas source of the invention of the '556 patent may include pressurized vinegar and baking soda or pressurized gas. The belt is worn around the waist of the user. The inflatable chambers which are spaced around the belt are attached thereto. This life saving belt does not provide for a means to release the inflated portion from the waist of the user or expand the belt such that it will rest around the upper portion of the torso.




Since the inflated chambers remain at the user's waist, the flotational support provided by the invention of the '556 patent would be awkward and unwieldy. The user would continuously have to tread water or swim in order to keep his head above water. An additional risk that may be caused by this type of support is that uneven inflation caused by malfunction of the chambers may cause the wearer to tilt so that his head is under water. Further, given that the support comes from around the waist or lower torso, the invention of the '556 patent is not suitable for the support of an injured or tired user. One who is injured or tired needs a device that will hold their head above water without any energy being expended by the user.




The vast majority of devices in this field which utilize canisters of compressed gas fail to recognize an obvious safety concern: rupturing of the canister. Pressurized canisters can rupture when struck with an appropriate amount of force. Generally, canisters associated with inflatable devices are located about the torso of the individual. In an emergency situation, the user may be falling into the water or onto debris that are in the water (if a boat capsized, for example). If the canister were to be between the user and the water or a hard object, it would be subjected to a forceful blow. In some situations, this or other forceful blows could cause the canister to rupture. Given that most of a human's vital organs are located in the torso, locating the canister around the torso of the user is an ill-advised risk.




These same inventions also fail to recognize that having a canister pressing into the wearer's back or torso is uncomfortable, especially when sitting or lounging in the sun, as many do while near the water.




There is a need for a flotational device that minimizes the potential for harm from compressed air canisters and incorporates safety features that is comfortable, fashionable and that may be worn inconspicuously by the user such that it does not interfere with the user's normal activities, both above the water, below the water and on land, and which may be activated when the user so desires.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




FIG.


1


(


a


) provides a view of the waist strap or belt-like portion


11


as would be worn by the user to firmly secure the present invention to the user's waist. This may be generally located inside the envelope portion


19


of the invention. The belt


11


is constructed of strong yet lightweight material, such as nylon. While materials recommended by the U.S. Coast Guard are preferable, any material that is strong and lightweight is appropriate. The belt has a buckle


12


that may be designed to make a clicking or snapping noise when closed. As shown in FIG.


1


(


b


), the belt


11


may be adjustable so that it can be made to fit different waist sizes.




FIG.


1


(


b


) provides a view of one embodiment of the belt or waist portion of the present invention when the inflatable chambers are inflated. The straps


15


are attached to the belt


11


at


13


and extend upwards towards the inflated chambers


32


. The straps may be attached by heat welding, glue, stitching, or any other appropriate method. In an alternate embodiment of the present invention, the straps are attached by the use of safeguards


14


. See FIG.


1


(


c


). A safeguard


14


is a piece of nylon, canvas or other strong suitable material that is attached to the belt and/or inflatable chamber that ensures that, should the straps


15


become separated from their attached area, they remain in their appropriate spacing around the invention.




A safeguard


14


is generally attached to the desired surface at two ends, with an open space in between the ends through which a strap


5


may move. These safeguards also ensure that the personal flotation device will be more securely fastened to the belt. On the inflatable chambers, the safeguards may be located on the side of the chamber closest to the wearer's chest and on the side that is open to the air.




FIG.


2


(


a


) provides a view of the compressed gas canister and ripcord mechanism. The ripcord


21


is depicted as having a handle


22


that is in the form of a rectangle. It should be understood that any shape which is easily grabbed, such as a ball or bar, would be appropriate for the handle. The ripcord


21


may be made of any durable material. The cartridge mechanism


24


which releases gas from the canister when the ripcord is pulled may be any such mechanism as is known in the art. The cartridge mechanism


24


is protected by a durable hard or semi-hard cover


23


. The compressed gas cartridge


25


may be secured by screwing it to the cartridge mechanism


24


.




Referring now to FIG.


2


(


b


), a portion of the ripcord


21


and the handle


22


stay on the exterior of the bathing suit so that the inflating device is readily accessible to the user. The compressed gas cartridge, mechanism and cover (not shown) are encased in a durable casing


26


as protection. This helps to ensure that the present invention will remain operative regardless of the activities in which the user engages prior to activating the inflation mechanism. This casing will protect both: (1) the gas canister against blows that could cause rupturing and (2) the user, should the canister rupture or explode.




FIG.


2


(


c


) provides a view of an embodiment of the present invention in its deflated state. In this embodiment, the invention resembles a pair of men's shorts or swim trunks. The inflatable chambers


32


(not shown) are enclosed in the envelope portion


19


of the shorts


30


. This portion of the invention which resembles an article of clothing


30


will be referred to as the body of the invention. The phrase “the lower portion of the invention” refers generally to the body of the invention and the elements and area associated therewith. Upon inflation, the chambers


32


expand rapidly, thereby exiting the body of the invention


30


through the flap


18


of the envelope portion


19


by breaking the stitching, opening corresponding hook and loop fasteners such as Velcro®, or by opening or breaking a similar closure. FIG.


2


(


c


) also shows the ripcord


21


, the handle


22


, and the pocket


29


enclosing the compressed gas cartridge


25


and mechanism


24


on the leg portion


27


. While the ripcord and handle are depicted as being located at the waist side of the compressed gas canister, it should be understood that the automatic inflation device could be inverted.




FIG.


2


(


c


) also shows that the handle


22


that is attached to the exposed portion of the ripcord


21


is held to the leg portion of the invention


27


by a strap


28


that lies over the handle. The strap


28


ensures that the ripcord


21


and handle


22


remain on the exterior of the invention and within easy reach of the user. The strap


28


may be any piece of cloth or other material. The strap


28


is attached to the leg portion


27


of the current invention by means of stitching, corresponding hook and loop fasteners such as Velcro® or other fastening means that are strong, but easily releasable. The strap


28


will prevent the ripcord from being pulled accidentally. Ripcord


21


extends from handle


22


into pocket


29


, where it is connected to the cartridge mechanism


24


(not shown). Pocket


29


, which is not accessible to the user, encloses the compressed gas cartridge, mechanism and casing, thus concealing them from the casual observer. Further, this prevents the compressed gas cartridge, mechanism and casing from moving excessively.




FIG.


2


(


c


) additionally shows that the belt


11


may be incorporated into the shorts


30


of one embodiment of the present invention. The buckle


12


may be seen as located on the exterior of the invention and accessible to the user at all times through a hole in the ‘flap’


18


of the envelope


19


. While not shown, the belt


11


extends from the buckle


12


and is located within the envelope portion. In this embodiment, inflatable chambers (not shown) are located in the envelope


19


that is formed in the upper portion of the shorts. The chambers


32


are rolled so that they push out against the ‘flap’


18


of the envelope


19


as the gas enters them. This pressure causes flap


18


to separate from the envelope portion


19


of the shorts in the area of the dotted line. In this way, the flap will be separated on one edge and the inflatable chambers will be released so that they may float to rest under the user's arms.




It should be understood that, while FIG.


2


(


c


) depicts the present invention as being a pair of man's shorts, the invention may also take the form of a man's swimsuit, a woman's one-piece bathing suit, a bikini, a swimsuit, a wetsuit, a drysuit, shorts, pants, or shorts that are designed to resemble skirts (skorts).





FIG. 3

illustrates the automatic inflating portion of the invention. The compressed gas cartridge


25


is attached to an inflating gas tube


31


that runs along the straps


15


(for simplicity, the belt is not shown in this figure) that hold the inflatable portion


32


of the present invention to the belt or waist portion


11


. In an alternate embodiment of the present invention, the straps


15


may hold the inflatable chambers to the portion


30


of the present invention that resembles an article of clothing. When the compressed gas cartridge


25


is activated by the ripcord


21


, gas quickly flows out of the cartridge, through the inflating tube


31


and into the inflatable portion of the present invention


32


. A partially cut-away view is shown so that it may be seen how inflating tube


31


, protecting tube


32


and strap


15


may fit together.




In

FIG. 3

, the inflating gas tube


31


is encased by a second tube


33


which is generally slightly larger and stronger that provides protection from any damage which may be caused by water activity. The second tube


33


may be made out of nylon, plastic or other strong, flexible material. The inflating gas tube


31


and the protective tube


33


meet an inflatable chamber


32


through a one-way airtight valve


35


that prevents gas from traveling back out of the airtight system of the present invention once the user has activated the gas canister.




In one embodiment of the present invention, the strap


15


has an interior hollow portion through which the gas tube


31


and protective tube


33


could travel to the inflatable portion


32


. In this embodiment, there is an entrance hole


34


where the gas tube enters the strap near the waist area and an exit hole


35


where the gas tube exits the strap near the inflatable chamber area. In another embodiment, the gas tube


31


and protective tube


33


run from the compressed gas canister to the inflatable portions


32


following a route that is substantially parallel to the straps. In yet another embodiment, the protective tube


33


is attached to the strap


15


by stitching (shown in

FIG. 3

with hash marks), heat welding, glue or the like.




FIG.


4


(


a


) provides another illustration of the manual inflation and whistle features of the present invention. There is a manual inflating attachment


41


that includes a mouthpiece


42


. This permits the user to inflate a potentially malfunctioning inflatable chamber by means of blowing air through the mouthpiece


42


.




The mouthpiece


42


is connected to an air tube


43


that is encased by a slightly larger and stronger second tube


44


which protection the air tube


43


, particularly from water activity. The second tube may be made out of nylon, plastic or other strong, flexible material. The air tube


43


and its protective tube


44


should be long enough so that the mouthpiece


42


may easily reach the wearer's mouth. This may be accomplished by including additional tube length in the envelope


19


.




The manual inflating attachment


41


has a one-way valve


45


located in close proximity to the mouthpiece


42


that prevents air from traveling back out of the airtight system of the present invention once the user has caused it to enter the system by breathing into the mouthpiece


42


of the manual inflating attachment


41


. The valve


45


also ensures that air remains in the tube


43


after the wearer has used the manual inflating attachment


41


. This ensures that the air tube will float in the water within easy reach of the user in case it is needed a second time.




FIG.


4


(


a


) also illustrates a whistle


46


directed in an opposite direction to the manual inflating mouthpiece


42


. In a preferred embodiment of the present invention, the whistle mouthpiece


47


points “up” towards the user's torso and the oral inflation mouthpiece


42


points “down” towards the user's feet when attached at the user's leg. This orientation permits easier access to the manual inflatable valve when necessary. The inflation mouthpiece/whistle combination may be attached or secured to the leg portion


55


of the present invention by means of stitching, corresponding hook and loop fasteners such as Velcro® or other fastening means that are strong, but easily releasable.




FIG.


4


(


b


) illustrates how the manual inflating portion and the whistle are connected to the inflatable chambers


32


. The manual inflating attachment is connected to the chambers by means of an air tube


43


that runs substantially parallel to the straps that hold the inflatable portion of the present invention to the belt-like portion of the present invention. The air tube


43


is contained inside a protective tube


44


. As with the gas tube


31


the air tube and its protective tube may be attached to or run along or inside the straps


15


of the present invention. Attachment to the strap may be achieved by way of stitching (shown in FIG.


4


(


b


) with hash marks), heat welding or other means sufficient to hold the tube


44


to the strap


15


and prevent separation of the two.




As further demonstrated in FIG.


4


(


b


), the air tube branches before reaching the chambers so that each chamber has its own supply of air. The protective tube


44


similarly branches. The ends of the air tube enter the inflatable chambers at their upper end through one-way valves


53


. These one-way valves


53


may be heat-welded or similarly sealed to the inflatable chamber


32


to ensure that there is no malfunction. The air tube


43


and the protective tube


44


should be long enough to reach the chambers with enough extra material to withstand any extra pull at activation while the mouthpiece is anchored on the “leg” portion of the present invention. The mouthpiece


42


of the manual inflating attachment and the optional whistle


46


are located at the lower end of the air tube


43


, where they are secured to the leg portion


27


(not shown) of the present invention.




FIG.


4


(


c


) provides an illustration of a view of the whistle/mouthpiece combination. The mouthpiece


42


and optional whistle


46


are enclosed in a casing


48


to protect them and keep them clean or free from debris. This casing may be of any material, but plastic is suggested for its lightweight yet strong properties. The casing


48


has a plurality of caps


47


which allow the user to access either the whistle, the mouthpiece, or both. The air tube (shown in protective tube


44


) is secured to the casing


48


through a one-way airtight seal similar to seal


53


.





FIG. 5

provides an inflated view of the present invention in which the inflatable portion is separated into two chambers


32


at the portions of the chest and back that are approximately half way between the user's shoulders (only the front portion shown). These chambers


32


may be joined to each other by any means as are known in the art. The gas tube


31


and air tube


43


run from the lower portion of the invention to the inflatable chambers generally along the same path as the straps


15


that run along the users chest. They may run also inside the straps. In order for the gas tube


31


and air tube


43


to reach both chambers


32


, the straps


15


that are on the portion of the invention that is to the front of the user each have several small holes


51


through which the tubes extend on their route to the middle of the user's torso. The air tube


43


and the gas tube


31


each “fork” or branch at


52


such that they may inflate both chambers at the same time and in the same amount. The second tubes


33


and


44


similarly branch. There is a one-way valve (not shown) at each point where a tube enters a chamber to ensure that a properly functioning chamber will remain inflated and not be affected by any subsequent disruption or loss of pressure in the inflating system. There is also a seal


53


around each air or gas tube as they enter their chamber to ensure that the chamber inflates properly and does not lose air or gas.




As shown in

FIG. 6

, in one embodiment of the present invention, there is a patch


61


which covers the area in which the air tubes


43


and the gas tubes


31


enter the inflatable chambers


32


. The patch may be heat sealed, glued, or otherwise joined with the inflatable chambers in an airtight manner. As a further means of protection, there may be an additional, similar patch that substantially covers this first patch


61


. It is preferable if the lengths of air tube


43


and gas tube


31


which run from the straps


15


to the valves


53


where they enter the inflatable chambers


32


are completely protected by such patch. The outermost patch may be reflective or brightly colored in order to attract attention to the user and facilitate rescue.




In an alternate embodiment of the present invention (not shown), there may be a patch on the inside of the inflatable chambers that covers any surfaces that may irritate the skin of the wearer after the invention has been inflated.

42


and whistle portion


46


of the present invention. There is a reflecting member


71


running along and encircling the body of the manual inflatable valve and whistle portion of the invention. This reflecting member


71


may take the form of an unbreakable mirror or any other reflecting device. The reflecting member


71


is shown in this embodiment of the invention as being hexagonal, but it should be understood that any shape which provides adequate reflection. The reflecting member may also be in the form of a pyramid so that it reflects light in all directions.

In one embodiment of the present invention, the rip cord and air canister are located on one “leg” of the invention, while the whistle and manual inflation tube should be located on the other. It should be noted that, for convenience in description, and because most people are right handed, the invention is described as having the air canister on the right and the whistle and manual inflation tube on the left. However, the present invention may be constructed with the manual inflation apparatus on either the left or right, the gas canister on either the left or right, or both on either leg.




The present invention has several safety features built into its design. First, the inflatable portion of the present invention is composed of at least two separate chambers such that the invention will provide flotational support in case of a malfunction by one of the chambers. In one embodiment of the present invention, these chambers meet on the front and back of the torso at the position that is approximately half of the distance between the user's shoulders. In case of a malfunction in the discharge of the compressed gas, the user can hold onto the inflated chamber with one arm and reach the manual inflation tube with the other arm. If the chambers were positioned such that they separated at the sides of the user's body, the user's head could be caused to be pushed either forward or back. This would be detrimental in the typical emergency situation, when the user is struggling to keep their head above water.




Another safety feature is the durable patches


61


which cover the area in which the air and gas tubes enter the inflatable portion


32


and protect the seal between the tubes and the chambers where the tubes enter the chambers. Since the patches are preferably airtight, they also provide a defense in the case of a leak in the one-way valve or the seal. In this manner, air will be prevented from escaping into the environment from this location.




The manual inflation tube is an additional safety feature. In case of a malfunction with the gas canister, the user may blow into the manual inflation valve, which is located within easy reach of their left hand. While being a slower form of inflation, it would still provide the user with flotational support. This valve would also be beneficial in the case of a slow leak. If the user was floating for a longer period of time and a slow leak developed, the user could counteract this through manual inflation.




Another safety feature is the placement of the compressed gas canister. If the canister ruptures, it can cause damage to the area surrounding it. Many flotation devices which use compressed gas canisters locate the canister on the torso of the user. In the case of a malfunction of the canister or cartridge mechanism, the placement of the canister on the user's leg is preferable since the thigh contains fewer vital organs than the torso.




A further safety feature is a whistle that is attached within easy reach of the user's hand. The whistle may be single-toned or play multiple notes. This will permit the users to attract attention to themselves.




The reflecting member


71


is a safety feature that may be used to attract attention to the user. It will reflect light in all directions, so it may attract attention to the user even if the user does not see the potential rescuer. This may also be utilized by the user to attract attention if the user is too tired to blow on the whistle.




The inflatable chambers of the present invention may be brightly colored in order to stand out against a watery background. The bright colors would also make the victim stand out against other backgrounds, like the brush of the shoreline. Reflective or neon patches or tape


61


placed on other surfaces of the present invention would similarly facilitate a rescuer's search.




Once activated, the safety device of the present invention cannot be reused by the wearer unless the re-packed and certified by the factory. There, the chambers are deflated and the canister of compressed gas is replaced. This ensures that the inflatable chambers and tubes are correctly packed in the envelope portion and that the safety device is in working order. Further, it prevents human error by those who are not trained to handle the preparation of the present invention from affecting the performance of the invention.




A depth valve or sensor gauge may be incorporated into the present invention such that if the user is pulled underwater to a predetermined depth (15 feet, for example), the increased pressure from the water would trigger the safety mechanism and cause the present invention to inflate, thus bringing the user to the surface. This could occur if the user was snorkeling and was caught in an underwater current. Alternatively, the user could be surfing, fall, potentially even hit his head, and be pulled under by a wave.




Preferably, the depth valve could be adjusted at the factory to pre-determined depths that are shallower for the novice and deeper for the more advanced swimmer. Thus, the present invention would allow people who are inexperienced with the water to be more comfortable, yet not inconvenience those who are more experienced with an early discharge.




Another benefit of the depth valve is that it could bring the bodies of drowned victims to the surface for easier location.




The present invention is designed so that it is comfortable and able to be worn for long periods of time. As such, the discomfort that is usually a disincentive for people putting on bulky and uncomfortable inflatable life saving devices prior to when they are needed is greatly alleviated. The present invention is sufficiently comfortable such that it may be put on when the user is getting ready to go boating, to the beach or to another activity near or involving water and worn all day. The ease and comfort of wearing the present invention will make it easier for the user to wear it for longer periods of time, making it more likely that the user will be wearing the present invention should any emergency arise.




Proper use of the present invention may be facilitated by printing, embroidering or otherwise placing the instructions for use on the invention within easy view of the user. These could be written or in the form of pictures.




The present invention, when inflated, provides flotational support around the torso of the user. Such support is more stable and secure than other means which tilt or angle the user in the water, since the angling of the user may inhibit swimming or turning motions. Additionally, such support is preferable in an emergency situation to those devices that force the user to hold onto them. In an emergency situation, the user may be panicked or injured. This may cause the user to let go of a detatched inflation device or to allow it to slip from his grasp. In contrast, since the user puts the inflatable portion of the present invention on before the emergency situation arose, he will not have to put it on, grab it or hold onto it in an emergency situation. Once the user activates the present invention by simply pulling on a readily accessible cord, the inflatable chambers of the present invention will rise to rest under the arms of the user. This is beneficial, especially for the tired or injured user.




The fact that the inflatable portions are anchored to the lower portion of the user provides additional security because this prevents the inflatable chambers from slipping over the head of the user. The user may relax, knowing that the inflatable portion will not slip off, even if he relaxes his arms or passes out.




Once the tube is inflated, the user may hold onto either the tube or the straps for a more secure feeling. The straps may also be used as a handhold by a rescuer who is trying to grab hold of the victim or tow them to safety. In the alternative, a rescuer may ‘hook’ a pole or similar object under the straps to pull the wearer to safety.




The belt closing mechanism may be designed to make a clicking or snapping noise. This will provide the user with audio assurance that the present invention is being worn properly.




The inflatable chambers, while preferably annular, may be U-shaped, half-round, rectangular, spherical or any other shape which is suitable for providing similar flotational support.




While the description above refers to particular embodiments of the present invention, it will be understood that many modifications may be made without departing from the spirit thereof. The accompanying claims are intended to cover such modifications as would fall within the true scope and spirit of the present invention.




The presently disclosed embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims, rather than the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
