Abstract
A person and a buoyant component can be attached while the buoyant component is detachably mounted on a boat. Also, flotation systems can include buoyant components with head openings and shoulder structures with arm openings. Also, a flotation system can further include a lanyard structure and an attachment structure connected to the lanyard structure and capable of attachment to a person, with the lanyard structure being sufficiently long to allow a range of motion when the buoyant component is fixed in position, such as mounted on a boat. Also, a flotation system can further include one or more detachably mountable structures allowing detachable mounting on a boat. The mounting can be sufficiently detachable and the lanyard structure sufficiently strongly connected to the person and the buoyant component and sufficiently short in length that, if the person goes overboard, the buoyant component detaches from the boat and goes overboard too.
Description
- This application claims priority from U.S. Provisional Application No. 60/749,452, filed Dec. 12, 2005 and incorporated herein by reference.
- The present invention relates generally to flotation of a person.
- A wide variety of flotation devices and techniques have been developed, particularly to protect people from drowning when boating. Although some flotation devices are designed to be thrown to a person who is already in the water, others are designed to be worn on a boat in case one unexpectedly goes overboard.
- U.S. Pat. No. 5,588,892 is one of many patents that have been issued on flotation devices, and describes examples of devices that can be worn similarly to vests. U.S. Pat. Nos. 6,537,119 and 6,638,126, describe examples of flotation devices that include a buoyant collar or member with a neck opening through which a person's head extends.
- It would be advantageous to have improved techniques for personal flotation.
- The invention provides a variety of embodiments, including methods, flotation systems, and products. In general, each embodiment involves a buoyant component.
- These and other features and advantages of exemplary embodiments of the invention are described below with reference to the accompanying drawings.
-
FIG. 1 is a perspective view of a person wearing a flotation system while being supported in a body of water by a buoyant component of the system. -
FIG. 2 is top view of components of the flotation system shown inFIG. 1 . -
FIG. 3 is a perspective view of components of an alternative implementation of a flotation system. -
FIG. 4 is a schematic diagram showing how a product that includes a flotation system similar to that inFIG. 3 can be installed on a boat. -
FIGS. 5A and 5B together are a series of cartoon-like scenes illustrating installation and use of a flotation system like those inFIGS. 1-4 . -
FIG. 6 is a schematic perspective view showing a person's range of motion while attached by a lanyard structure to a buoyant component as inFIGS. 1-5B . -
FIG. 7 is a cutaway view showing a person sitting in a boat while attached by a lanyard structure to a buoyant component as inFIGS. 1-5B . -
FIG. 7A is cutaway view similar to that inFIG. 7 , showing the person going overboard and the buoyant component detached from the boat. - In the following detailed description, numeric values and ranges are provided for various aspects of the implementations described. These values and ranges are to be treated as examples only, and are not intended to limit the scope of the claims. In addition, a number of materials are identified as suitable for various facets of the implementations. These materials are to be treated as exemplary, and are not intended to limit the scope of the claims.
- As used herein, the term “flotation” refers to buoyancy-based support of a person in a liquid such as water, whether in an indoor or outdoor pool of any kind or in an ocean, lake, river, stream, pond, or any other body of fresh- or saltwater. The term “person” refers generally to one's body together with other items ordinarily worn on one's body, including clothing, jewelry, eyewear, and so forth. A device that can support a person solely by flotation is referred to herein as a “personal flotation device” or “flotation device”, whether or not it satisfies any particular criterion; in other words, a flotation device may not meet requirements of the U.S. Coast Guard or other agencies. A “flotation system” is a combination of two or more parts or components that together can function as a flotation device; one component can, for example, be a “buoyant component”, meaning a component that is buoyant in water.
- The implementations described below address problems that frequently arise with flotation devices. One important problem is that people seldom wear flotation devices. In general, most flotation devices must be worn in order to be helpful when one is unexpectedly thrown overboard, but studies have shown that people typically do not wear flotation devices, even when legally required. Another set of problems relates to putting on flotation devices when in the water. Furthermore, the implementations address problems in attaching flotation devices to a person's body while on a boat.
- In the implementations described below, flotation systems or parts or components of flotation systems are referred to as “attached” to persons or to other things or vice versa, and operations that are performed that “attach” flotation systems or parts or components of flotation systems to persons or to other things or vice versa; the terms “attached”, “attach”, and related terms refer to any type of connecting that could be performed in the context. In contrast, the more generic term “connecting” includes not only “attaching”, but also making other types of connections such as between parts formed as a single piece of material by molding or other fabrication.

FIG. 1 showsperson 10 supported inwater 12 byflotation system 14.FIG. 2 is a top view offlotation system 14, further illustrating features shown inFIG. 1 . -
Flotation system 14 illustratively includes closed-cell foam component 16, a buoyant component that a person can wear to remain afloat in water in which the person cannot stand.Component 16 is illustratively rectangular and box-shaped, measuring approximately 12″×24″ with a thickness of 2-3″, but could have any other suitable shape and dimensions. It is contemplated thatcomponent 16 will be sufficiently large to provide approximately 18 lbs. of flotation. In general,component 16 could be provided in different sizes suitable for differently-sized people.Flotation system 14 could include any other appropriate type of buoyant component, such as a semi-hard, hollow, lightweight plastic component formed by a roto-molding or blow-molding process, as from Sterling Technologies of Erie, Pa. Also,component 16 could include fabric filled with inherently buoyant material, such as Styrofoam® or could be an inflatable structure. -
Component 16 has opening 20 defined in it, which could, for example, be a result of cutting or otherwise removing material fromcomponent 16 or could result from molding or otherwise producingcomponent 16 to have opening 20 defined in it.Opening 20 is illustratively circular and approximately 10″ in diameter, but could have any size or shape that allows the head ofperson 10 to easily pass through it. - Attached to
component 16 arestraps Straps loop openings 30, examples of shoulder structures that can be connected to a buoyant component. Between each ofstraps component 16 is a respective arm opening through which the arms ofperson 10 are shown extending inFIG. 1 .FIG. 1 also shows, however, thatstraps alternative positions component 16, so thatflotation system 14 could be worn with either side ofcomponent 16 upward.Straps loop openings 30 as illustrated inFIGS. 1 and 2 . - As illustrated in
FIG. 1 ,component 16 is structured and each ofstraps component 16 so that the head ofperson 10 is held out ofwater 12 by buoyancy when the head extends through head opening 20 and at least one of the arms ofperson 10 extends through the respective arm opening of the respective one ofstraps FIGS. 1 and 2 also illustratestructure 40, connected tocomponent 16 and also capable of being attached toperson 10. -
Structure 40 includes spring-actuatedsnap hook 42, an example of a clasp, clamp, or other part ofstructure 40 that can be connected tocomponent 16. In the illustrated example,hook 42 is connected tocomponent 16 by being attached tostrap 24, but a part ofstructure 40 could be connected tocomponent 16 in any suitable way. In particular,hook 42 could alternatively be connected to the part ofstrap 24 on the either side ofcomponent 16, with connection on one side being shown inFIG. 1 and connection on the other being shown inFIG. 2 . Similarly,snap hook 44 is part of an attachment structure that can be attached toperson 10. In general, an advantage of spring-actuated snap hooks as illustrated is that they are strong, inexpensive, and easily and quickly attached and detached. - In the illustrated example, the attachment structure also includes
belt 46 which can be attached around the waist ofperson 10.Belt 46 includesring 48, so thathook 44 can easily be attached to and detached frombelt 46 by connecting toring 48, thus connectingbelt 46 tostructure 40. - Although illustrated as part of
structure 40,belt 46 could take many different forms, and is but one example of howstructure 40 could be attached toperson 10.Belt 46 could be the trouser belt ordinarily worn byperson 10 but fitted with a strong loop such as a brass ring, a key ring, or the like, to accommodatesnap hook 44 or another clasp or clamping device onstructure 40; this technique may be appropriate in situations in whichperson 10 is wearing clothing with a belt that is not covered by a jacket and is therefore easily accessible. In another approach,structure 40 could itself include a suitable length of line that can be wrapped around the waist ofperson 10 and snapped, clasped, clamped, or otherwise attached to itself bysnap hook 44 or other clasp or clamping device; this approach may be appropriate in emergency situations, for example, but may be too cumbersome for everyday use. Alternatively,belt 46 could be a separate belt, advantageously designed to be universally functional, lightweight, appropriate in strength, durable in outdoor use, and structured withring 48 or other part to accommodatesnap hook 44 or other clasping or clamping device.Belt 46 could be provided in more than one size, to accommodate differently sized waists; in each size, however,belt 46 could be adjustable in length, as would be possible, for example, for a webbed belt with plastic interlocking buckles at its ends. - Rather than attaching
structure 40 to the waist ofperson 10, it could conceivably be attached to any other appropriate part of the body ofperson 10. Other parts may, however, be disadvantageous. For example, attachment to an arm, a leg, or the neck would be cumbersome and would have an abnormal appearance for typical boating situations, while a belt around the waist is neither cumbersome nor abnormal. Also, as described below,flotation system 14 is designed to be put on easily and quickly donned byperson 10 after falling intowater 12, which might be difficult ifstructure 40 were tied or otherwise attached to a wrist or ankle, thus interfering with the natural movement of one's arms and legs to keep from sinking and to graspcomponent 16. -
Structure 40 is an example of a “lanyard structure”, meaning a structure that includes a rope or other line-like part and can be used to connect things on a boat.Structure 40 could be implemented in a wide variety of ways. In a simple implementation,structure 40 can include one or more strands of nylon rope or another appropriate line. - As shown in
FIGS. 1 and 2 ,structure 40 can have a length between snap hooks 42 and 44 that is substantially longer than necessary whenflotation system 14 is being worn byperson 10. As explained in greater detail below, the length ofstructure 40 can be long enough to allow person 10 a range of motion whencomponent 16 is fixed in position, such as by being mounted on a boat. For the purpose of mounting,flotation system 14 also includes Velcro® strips 50 and 52, examples of detachably mountable structures that allowcomponent 16 to be detachably mounted on a boat. -
Strips component 16 for detachable mounting to a boat. Hook-and-loop material such as from Velcro® is an especially convenient fastening material, especially if structured to withstand the effects of water, humidity, sun, and other environmental factors present on a typical boat. Various mechanically mounted structures could also be used, such as suction cups oncomponent 16, a hook oncomponent 16 to hang over the inside of a boat, or knobs or other protuberances fromcomponent 16 that can be attached to spring clamps on the inside of a boat that extend horizontally to allowcomponent 16 to be pressed between two arms and to be pulled out whenstructure 40 is pulled. Also,component 16 could be attached directly to the inside of a boat using adhesive of a type that would break whencomponent 16 is pulled upon bystructure 40. In general,component 16 must be held firmly enough against the boat so that wind will not blow it from its position. - A prototype flotation system similar to that shown in
FIGS. 1 and 2 has been successfully implemented and tested. But many other implementations would come within the scope of the invention. -
FIG. 3 shows an alternative implementation to that shown inFIGS. 1 and 2 .Flotation system 54 illustratively includescomponent 56, a blow-molded, hollow, water-tight, buoyant box dimensioned similarly tocomponent 16 as described above, and with opening 58 similar in size to opening 20, above.Component 56 also includes protrudingknobs component 56. Compared to a closed-cell foam implementation, a blow-molded implementation, such as with techniques mentioned above in relation toFIGS. 1-2 , is expected to be advantageous: It will be less expensive for mass production quantities, it will look better due to rounded exterior surfaces, mounting structures such asknobs - At each corner of
component 56, one ofknobs 60 is formed, illustratively extending outward fromcomponent 56 in its lengthwise direction. Each ofknobs 60 has a hole through it, so that straps 64 and 66 can be attached as shown, such as by knotting. As can be seen, the positions of arm openings instraps component 56—the arm openings will be available regardless of which side ofcomponent 56 is upward. -
Knob 62 similarly has a hole in it for knotting or other attachment ofline 68, part of the lanyard structure offlotation system 54; the remainder of the lanyard structure can be implemented as described above in relation toFIGS. 1 and 2 .Knob 62 is illustratively shown at one of the sides, extending laterally outward fromcomponent 56. As withknobs 60 andstraps component 56 does not affect the freedom of movement ofline 68, due to the positioning ofknob 62. -
FIG. 4 illustrates in greater detail how a flotation system similar tosystem 54 could be installed for use on a boat. As shown, the flotation system can be packaged in the form ofproduct 70 withbox 72 holding unassembled parts or components of the flotation system as well as other components necessary for installation.Box 72 is merely an illustrative container, and various other types of containers could be used. -
Product 70 includes Velcro® strips 80 and 82, examples of fixed mounting structures that can be attached to a boat. As illustrated by the arrows with the adjacent circled numbers “1”, the installation process can begin by mountingstrips gunwale 84 abovedeck 86.Strips gunwale 84 in any appropriate way, such as with an adhesive backing or other appropriate attachment. Similarly, as noted above, strips 80 and 82 are but one example of many different types of fixed mounting structures that could be used. - Once strips 80 and 82 have been attached, subsequent installation operation includes mounting
component 56 ongunwale 84, as indicated by the arrow with the adjacent circled number “2”. For this purpose, strips 80 and 82 must be positioned with the same spacing asstrips component 56. When mounted ongunwale 84,component 56 is out from underfoot. - Comparing
components 56 inFIGS. 3 and 4 , one can see thatcomponent 56 inFIG. 4 could be obtained by turningcomponent 56 inFIG. 3 upside down and positioning it withknob 62 andline 68 to the rear ofbox 72 and therefore not visible. Alternatively, the two could be alternative implementations, withcomponent 56 inFIG. 4 being attached similarly tocomponent 16 inFIGS. 1 and 2 . If attached similarly tocomponent 16 rather thancomponent 56 as inFIG. 3 , another installation step, which could be performed before, between, or after the operations described above, is to connectsnap hook 42 ofstructure 40 tocomponent 16, such as by attaching it to strap 24. Here again,snap hook 42 could be attached to any other appropriate part of the flotation system for connection to the buoyant component, possibly including an additional component (not shown) specially designed for this purpose. -
FIGS. 5A and 5B (not drawn to scale) show a series of cartoon-like diagrams illustrating in greater detail how a system likeflotation systems person 10 is installing or otherwise interacting with aflotation system 100, which could be implemented as described above or in any other suitable way.Flotation system 100 includesbuoyant component 102 withhead opening 104 and also includeslanyard structure 106. - In
scene 110, which can occur afterstrips person 10 mountsbuoyant component 102 ongunwale 84, such as by positioning strips likestrips strips scene 112,person 10 connectsstructure 106 tocomponent 102, such as by attachingsnap hook 42. Then, inscene 114,person 10 attachesstructure 106 to him- or herself, such as by putting onbelt 46. As noted above, the operations shown inscenes person 10 is not wearingcomponent 102 but is remotely attached to it bystructure 106. -
FIG. 6 illustrates the situation that exists after the operations inscenes person 10 is attached to one end ofstructure 106. The other end ofstructure 106 is attached tocomponent 102, which is detachably mounted ongunwale 84.Structure 106 has a length such thatperson 10 has a range of motion ondeck 86, the outer boundary of which is indicated byline 120. Althoughstructure 106 can have any appropriate length, in many situations it will suffice ifperson 10 can move roughly 6′ from a seated position—for further movement or when docked,person 10 could detachstructure 106, such as by detachingsnap hook 44. As a result of the range of motion,person 10 can move about ondeck 86 to perform various activities, such as fishing over the side of the boat, stowing or retrieving gear in a nearby part of the boat, or moving to a nearby seat or other position ondeck 86.Deck 86 is illustrative of a “deck area”, meaning a deck, bottom, or other floor-like part of a boat on which a person can walk or otherwise move about the boat. -
Scene 130 inFIG. 5A illustrates a situation like that shown inFIG. 6 , but withperson 10 about to be thrown overboard fromdeck 86 overgunwale 84 and intowater 12. As shown inscene 132,structure 106 can extend to its full length asperson 10 falls towardwater 12, at whichpoint component 102 begins to detach fromgunwale 84 due to the force exerted by the weight ofperson 10 throughstructure 106. As shown, ifperson 10 goes overboard from within the range of motion permitted bystructure 106,component 102 is sufficiently detachable fromgunwale 84 andstructure 106 has sufficiently strong connections toperson 10 and tocomponent 102 and a sufficiently small length, such as between snap hooks 42 and 44, thatcomponent 102 detaches fromgunwale 84 and goes overboard connected toperson 10 bystructure 106. Then, as shown inscene 134,component 102 is completely detached from gunwale 84 and followsperson 10 intowater 12. -
Scene 140 illustrates howperson 10 can manually pull onstructure 106 in order to pullcomponent 102 through the water towardperson 10. Whencomponent 102 is close toperson 10,person 10 can manually graspcomponent 102 and move it so that the head ofperson 10 passes throughhead opening 104, as shown inscene 142.Person 10 can then, with bended arms, locate thearm openings straps straps person 10 can move the arms through the arm openings, as shown inscene 146. - Finally, as shown in
scene 148,person 10 can lower the arms to holdcomponent 102 in place on the shoulders and around the neck ofperson 10. In this position, the bulk of the body can hang substantially straight down, supported by the straps or other structures that extend under the armpits.Component 102 is effectively locked in place across the shoulders because the natural position of the arms at rest keeps each of the straps in position without further effort. The head is positioned approximately straight up above the surface ofwater 12. -
FIGS. 7 and 7 A illustrate two scenes depicting another implementation in whichflotation system 100 as inFIGS. 5A-6 is used inboat 200, a small boat with gunwale height of approximately 2 feet and beam width of approximately 6 feet. Such boats are appropriate, for example, for fishing or other recreational purposes. Althoughdevice 100 includes features described above in relation toFIGS. 5A-6 ,lanyard structure 106 may be shorter than would be appropriate on a larger boat, to ensure thatbuoyant component 102 is detached fromboat 200 ifperson 10 goes overboard. In addition,person 10 will generally sit onseat 202 rather than walking around as inFIGS. 5A and 6 . - In
FIG. 7 ,person 10 is sitting onseat 202 and fishing. Meanwhile,person 10 is wearingbelt 212, which is connected tocomponent 102 bylanyard structure 106. Because of the small size ofboat 200,structure 106 lies slack in the bottom of the boat, but is sufficiently short to detachcomponent 102 ifperson 10 goes overboard. - In
FIG. 7A ,boat 200 has tipped andperson 10 has lost balance and is about to go overboard. As a result,structure 106 has tightened anddetached component 102 from its mounting toboat 200, andcomponent 102 will followperson 10 overboard. Once in the water,person 10 can usestructure 106 to retrieve and wearcomponent 102, as described above in relation toFIG. 5B . - A flotation system implemented as described above is particularly advantageous compared with flotation devices that must be worn in order to be useful. With the implementations described above, a person can be attached to the flotation system yet be free to move around an area of the boat. Then, if thrown overboard, the person will be followed into the water by the flotation system's buoyant component and will be able to retrieve it and wear it while in the water.
- Use of flotation systems implemented as in
FIGS. 1-7A illustrates examples of a method that includes attaching a person and a buoyant component while the buoyant component is detachably mounted on a boat near a deck area. In specific implementations, the method can also include attaching a lanyard structure with a first part connected to the person and a second part connected to the buoyant component, and the lanyard structure can have a sufficiently great length between the first and second parts that the person has a range of motion on the deck area. The method can also include, before attaching the person and the buoyant component, detachably mounting the buoyant component to the boat. - Use of flotation systems implemented as in
FIGS. 1-7A also illustrates examples of a method of using a flotation system that includes a buoyant component with a head opening defined therein and with one or more shoulder structures connected to it. Each shoulder structure has a respective arm opening through which an arm can be put.
