Personal flotation device with passive location and identification system and method of use

Abstract

A Personal Flotation Device (PFD), in the form of a vest or like garment, and having a quiver-like receptacle attachment, hinged to the garment for flexibility, is provided. The quiver attachment houses a mast and flag attached to a small flotation device, such that when the user enters the water the flotation device causes the mast and attached flag to rise so that the flag can be seen from a distance and the wearer identified thereby. The quiver element is attached such that it can place the extended mast and flag unobtrusively and at a distance from the wearer's head for comfort. The quiver element comprises a housing for the mast and flotation device and is permeable to water; the quiver element is shaped to guide the mast and flag linearly at an angle to the longitudinal axis of the wearer. The device allows for the flag to be interchanged with other flags so as to better identify the wearer from other users.

DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENT

(19) While the present invention is susceptible of embodiments in various forms, there is shown in the drawings and will hereinafter be described some exemplary and non-limiting embodiments, with the understanding that the present disclosure is to be considered an exemplification for the invention and is not intended to limit the invention to the specific embodiments illustrated. In this disclosure, the use of the disjunctive is intended to include the conjunctive. The use of the definite article or indefinite article is not intended to indicate cardinality. In particular, a reference to the object or a object is intended to denote also one of a possible plurality of such objects.

(20) Referring now to the drawings, in one embodiment of the invention, a personal flotation device (PFD), here in the form of a life vest, 10 is shown, in FIG. 1, having an identification and location system 11 comprising a receptacle or pouch 12, a receptacle separator 14 and a buoyant locator/identifier 15 (most clearly shown in FIG. 9). The receptacle separator 14 acts as a divider between the life vest 10 and receptacle 12, allowing receptacle 12 to position itself angularly away from the life vest wearer's 17 head 19, allowing, as will be explained below, for the system 11 to be deployed while maintaining separation between the locator/identifier 15 and the wearer's head 19 in all directions. In this way, the identification and locator/identifier 15 can be deployed without disturbing the wearer 17. Additionally, when created with a flex material, as shown in the drawing figures, receptacle separator 14 allows receptacle 12 to distribute the forces created by the water entering the buoyant locator/identifier 15 such that it lessens the feeling that user being dragged or pulled by the extending flag 52.

(21) In some embodiments, the receptacle separator 14 may be comprised of a durable, flexible material that angles the receptacle 12 away from the life vest 10 as substantially shown in FIGS. 3 and 10. In some embodiments of the present invention, separator 14 may be made out of a mesh material to allow the free flow of water therebetween and to decrease the overall weight of the life vest 10. It will be understood by persons having ordinary skill in the art that the separator 14 can be made from different materials and in different ways, including the use of materials that can flexibly attach the separator 14 to the life vest 10 so that the separator 14 can pivot away from the life vest 10, including one or more cord, chain, rope, or solid material panel or panels including such items made from cloth, plastic, metal or synthetic materials.

(22) As shown in FIGS. 1 through 3 (and others), receptacle 12 comprises a front panel 12a and a rear panel 12b, a bottom 16, a lower opening or window 18 in front panel 12a, a top 20, and an upper window 22 in front panel 12a. Front panel 12a and rear panel 12b are attached together at their sides and bottoms to form receptacle 12, which as illustrated can be formed in the manner of a quiver for arrows, having an opening 30 in top 20 such that a locator/identifier 15 can be placed therein. While the term window is used in describing the openings in panel 12a, persons having ordinary skill in the art will understand that the windows are substantially panels of material perforated to allow water to more readily enter receptacle 12 when it is submerged but limiting the amount of open area so that structural integrity is maintained. The perforations 12p can be of any desired shape and can be made into a desirable pattern both for functional and aesthetic reasons. It will be understood, by persons having ordinary skill in the art that, receptacle 12 can be made in any manner that allows both the placement of a locator/identifier 15 and the infiltration of water therein, and that the illustrated embodiment is merely one exemplary of this element of the present invention. Further, it will be understood that locator/identifier 15 can be easily removed from receptacle 12 so that it can be cleaned, repaired or replaced as needed or removed to reduce weight in situations where the device is not needed.

(23) In some embodiments, receptacle bottom 16 can be fully enclosed in a pre-formed shape, such as the curved edge shown in FIGS. 1 through 3 (and others); additionally, it will be seen that it is not necessary to attach the bottoms of panels 12a and 12b for their entire lengths in order to enclose locator/identifier 15; and that allowing the bottom to be partially open can aid in the entry of water into receptacle 12. In the present embodiment, lower window 18 comprises an open section in panel 12a, formed and configured to match the structure of receptacle 12 and is located adjacent to bottom 16; upper window 22 is placed adjacent to receptacle top 20 and comprises a similar structure to window 18. It will be understood by persons having ordinary skill in the art that the open sections in panel 12a can be made of different sizes and shapes from those show and from each other in anyone device.

(24) As shown in the figures, in the present embodiment, receptacle top 20 comprises flaps 24 adjacent to opening 30. It will be understood that flaps 24 can either be attached to receptacle 12 as separate sections or can be formed as part of rear panel 12b, wherein once assembled flaps 24 can extend over and onto front panel 12a, all without departing from the novel scope of the present invention. Each flap 24 individually extends alongside the edges of the receptacle top 20, partially covering opening 30 but allowing an open area 30a near the center of opening 30. As shown in FIG. 4, flaps 24, at top 20, comprise an exterior surface 28 and an interior surface 26 and flap interior surfaces 28 comprise fastening means such as, for example, hook and loop fasteners, snaps or buttons and others, to enclose and retain locator/identifier 15 within receptacle 12.

(25) Referring now to FIGS. 5 and 6, there is shown the elements of locator/identifier 15, shown outside of receptacle 12 for illustrative purposes. It will be seen that locator/identifier 15 comprises a housing 32 created to fit closely within and work in cooperation with receptacle 12. Housing 32 comprises a first and second body shell 33 sealed together with a formed top 38 and bottom 36. Persons having ordinary skill in the art will understand that housing 32 can be created in any manner that provides a structural enclosure for the elements of locator/identifier 15. Referring now to FIG. 7, which is a cut-away illustration of elements, in place, of life vest 10, receptacle 12, separator 14 and locator/identifier 15. It will be seen that housing 32 has an exterior surface 40 and an interior surface 42; housing support exterior surface 40 is shown adjacent to the inner surface 12i of receptacle 12. In the present embodiment, the housing 32 is shown to be comprised of two separate sections 33 fastened together using any one or more of adhesives, fasteners (such as screws, rivets, plastic connectors, metal connectors), or molded together in any number of processes well known to persons having ordinary skill in the art.

(26) FIG. 7 further illustrates a float 44 and a mast or pole 46 within housing 32; float 44 is shown adjacent to the housing interior surfaces 42 and is generally circular in shape to fit within the bottom 36 of housing 32. It will be seen in FIG. 9 that float 44, in the preferred embodiment, is disk shaped and formed either of buoyant materials or as an empty shell to provide buoyancy. A mast 46 connects to float 44 at a first end 46a and its second end 46b extends through the hollow housing 32 (see, FIGS. 6 and 8). As shown in FIGS. 5 and 6 the mast 46 exits the housing 32 through the housing end-hole 48 located at the top portion of housing 32. It will be understood that mast 46 can be comprised of either substantially rigid or substantially flexible material depending on the application of the locator/identifier 15 and other aspects of the present invention. In some embodiments, the mast 46 may be comprised of a substantially soft flexible, extremely lightweight material that has a tendency not to absorb water or other liquids.

(27) As shown in FIG. 9, locator/identifier 15 comprises a mast 46, a stopper 50, a flag 52, and an end cap 54, and as shown in FIG. 6, mast 46 is held partially outside of housing 32 and stopper 50, flag 52 and end cap 54 are entirely outside of housing 32. Stopper 50 is designed to provide a connection point for flag 52, such that different flags can be interchanged to provide a variety such that the wearer can be more readily found amongst other such devices in use. Referring to FIG. 1A, it can be seen that the flag 52 can be removed from mast 46 for storage or to interchange flags.

(28) In a case where a mast that is of smaller length is used, the stopper 50 further limits the amount of retraction of the mast 46 into the housing 32 and also keeps flag 52 from sliding into housing 32. Stopper 50 and end cap 54 are formed to the shape and size of mast 46 on each end of the flag 52 as shown in FIGS. 5 and 6. In some embodiments, stopper 50 can be comprised of one main section or two separate sections. Stopper 50 and/or the end cap 54 can be either statically or dynamically positioned on mast 46. Further, stopper 50 and/or end cap 54 can be comprised of a substantially soft or substantially rigid material that has the tendency not to absorb water or other liquids. End cap 54 in a preferred embodiment is rounded so as to help prevent injury from an unprotected mast 46. In yet another form, flag 52 may contain a message area where messages or other information can be placed on flag 52 itself, as an additional safety measure (such things as a telephone number or identifying information can be placed thereon).

(29) Referring again to FIGS. 5 and 6, housing 32 further comprises a housing support end hole 48, extending from the receptacle opening 30 (as shown in FIGS. 1-3). In some embodiments, the receptacle flaps 24 adjacently form and fasten around the housing support end hole 48 as shown in FIGS. 1 to 5.

(30) In one embodiment of the invention, float device 44, when outside of water, sits in its neutral position adjacent to the bottom portion of the housing 32. In some embodiments, float device 44 can be comprised of a substantially solid but buoyant cylinder such as a hockey puck. In an alternative form, float device 44 may be substantially cylindrical with a hollow or solid core either substantially larger or smaller than a hockey puck. In yet other forms, the cross-sectional area of the housing 32 and/or float device 44 may be square, octagonal, circular, or a variety of other shapes and cross-sections provided that float device 44 can intake sufficient amount of force to raise or extend the flag system 15. In an alternative embodiment, float device 44 is not required; in this form, mast or pole 46 acts as the float device within the housing 32.

(31) Referring to FIGS. 5 and 8, it will be seen that housing 32 may be have a plurality of water inlet openings 34, a housing bottom 36, and a housing top 38. In some embodiments, housing bottom 36 and housing top 38 can be formed and connected by flat surfaces of housing 32. All of the flat surfaces of housing 32 may comprise water inlet openings 34; such openings 34 can be spaced in a curved or wave-like configuration as illustrated in FIG. 5 or in any manner fixed or random as desired or desirable. In an alternative form, housing 32 can be made either entirely or partially of screen or mesh materials and the water inlet openings 34 can then be part of such screen or a mesh material. FIGS. 2 and 12 show the device in use with mast 46 extended through length 56, to illustrate the mechanism of the life vest system 10 when the float device 44 is forced upward from water entering the housing 32 through the water inlet holes 34.

(32) FIGS. 1-2 and 11 further illustrate the traditional structures of a life vest such as a left arm opening 58, a right arm opening 60, a neck opening 62, a front vest locking system 64, adjustable straps 66, and a front zipper 68. In an alternative embodiment, these traditional structures may be adjusted in shape, size, and/or configuration to better equip to the life vest system 10. Further, it will be understood that the vest of the present invention can be created with neutral buoyancy such that the wearer can be in the water and not in a lifesaving position (that is the buoyancy of the vest of the invention need not lift and, as necessary, rotate the wearer to place the wearer's face at the surface)as the vest can be used while playing, the lifesaving mode is not necessary to daily use and would inhibit play. Instead the vest could act as water wings to help buoy the user without inhibiting play. Additionally, as shown in FIG. 12, the device can include a locking ring 70, or like item, to clamp flag 52 in an erect position while out of the water, so as to help identify and locate the wearer on land. Locking ring 70 can be made in any manner well known to persons having ordinary skill in the art.

(33) It will be understood that an identification and location system 11 made of a receptacle or pouch 12, a receptacle separator 14 and a buoyant locator/identifier 15 can be made separate from a PFD 10, as shown in FIG. 13, and provided with attachment means 74, such as the strap system shown, so that it can be worn separately, or with fasteners, such as hook and loop fasteners or snaps (not shown) so that it can be added to existing PFDs 10 or any type of clothing or object, to provide similar passive identification and location means in other situations where floatation and water are not necessarily and an issue, but location in large crowds is paramount, without departing from the novel scope of the present invention.

(34) The above described location and identification systems and their components can be made of a variety of different materials. In some embodiments, it can be made of plastic, metal, wood, foam, nylon and/or a variety of different materials and/or combination of materials to allow for proper operation of the life vest system as described herein. Specific embodiments of novel methods and apparatus for construction of the Personal Flotation Device with Passive Location and Identification System and Method of Use according to the present invention have been described for the purpose of illustrating the manner in which the invention is made and used. It should be understood that the implementation of other variations and modifications of the invention and its various aspects will be apparent to one skilled in the art, and that the invention is not limited by the specific embodiments described. Therefore, it is contemplated to cover the present invention any and all modifications, variations, or equivalents that fall within the true spirit and scope of the basic underlying principles disclosed and claimed herein.
