Description




FIELD OF THE INVENTION




This invention pertains to a signaling device to be worn by a person, and more particularly, to an extensible device which automatically extends to signal the location of a person upon activation of a release mechanism.




BACKGROUND OF THE INVENTION




A number of devices have been developed for signaling the location of a person in the water. It is well known that on an open body of water, particularly one interrupted by waves or other surface irregularities, it can be extremely difficult to locate a person floating in the water, even at relatively close range.




For that reason, a number of inventions have been developed over the years to signal the position of a person in the water. Typical of these devices are those disclosed by Rousseil, U.S. Pat. No. 51,971, Ledochowski, in U.S. Pat. No. 309,032, and Smith, in U.S. Pat. No. 988,830, all of which depict flotation devices to which segmented flag staffs with signaling flags may be assembled and attached.




It is also well known to affix such flag staffs and signaling flags to the flotation vests of those engaged in water sports, as is taught by Oberg, in U.S. Pat. No. 4,035,856, Roe, in U.S. Pat. No. 4,598,661 and Melendez et al., in U.S. Pat. No. 4,752,264. These inventors have developed either fixed or extensible signaling means particularly useful for water skiers.




Efforts have also been made to produce signaling devices which are automatic, extending a flag or warning marker above the head of a person in the water, for example, as taught by Chraghchian et al., in U.S. Pat. No. 5,083,956. This type of device, however, is limited in that the elevation of an extensible signal which relies strictly on flotation, as does Chraghchian, which is limited by the length or travel of the floatable, buoyant element which extends the signal. While efforts at deployment of signaling devices further above the body of the person wearing the device have been attempted, for example, by Crofford, as shown in U.S. Pat. No. 827,350, such devices require a complicated release mechanism which is not easily reusable.




It is apparent, therefore, that there is a need for an improved personal signaling device which deploys at a much greater height from the body of the person, in a method requiring only the simplest of mechanical elements, and which is readily restowable and reusable.




SUMMARY OF THE INVENTION




The present invention, therefore, is an extensible signaling device designed to be integrated with or attached to an article worn by a person, such as a flotation vest.




The device comprises a flag attached to a flexible elongate rod which has sufficient stiffness to maintain an erect configuration when deployed, yet sufficient resilience to allow it to be collapsed in a coil and contained within an enclosure when not in use.




The natural resilience of the rod material is such that release of the rod from its confinement in a container results in the self-deployment, by uncoiling of the rod to its extended position.




The invention is designed to be integrated with a life vest, such as that which might be worn by a water skier, or to be contained within a separable enclosure which may be affixed to such a flotation device, or to any other article of apparel which may be worn by a person. In a still further embodiment, the device may be easily incorporated into an outdoorsman's knapsack or outerwear, allowing the deployment of the warning device by persons other than water skiers, for example, snow skiers in avalanche areas, or hunters or hikers in tall grass environments.

DETAILED DESCRIPTION OF THE EMBODIMENT




The invention and its operation will be easily understood by reference to

FIGS. 1 through 3

. In one embodiment of the invention, an individual, such as a water skier


12


is provided with a self-contained signal assembly invention


10


. The invention comprises a compartment


20


which may be permanently or removably attached to a flotation device


14


, such as a life jacket or life preserver, typically of the vest-type as worn by those participating in water sports. Such flotation device


14


is preferably equipped with fasteners


16


which allow easy donning and removal of the device


14


. The flotation device


14


is provided with a guide


34


through which may be passed a rip cord


32


, which in turn, is provided with a handle


36


. The rip cord


32


engages a closure


30


which holds the compartment


20


in a closed position. Closure


30


may be any of a number of well known rapid opening and closing type closures, such as a conventional zipper, or a hook and loop type fastener. Preferably, the closure


30


traverses fifty percent or more of the perimeter of the compartment


20


. The compartment


20


may be either rigid or flexible. In an embodiment incorporating a rigid compartment


20


, the compartment


20


comprises a hinged enclosure which is held in a closed position by closure


30


. Flexible rod


22


, when stored, approximates the configuration of a helical spring, and urges the two halves of the compartment


20


apart. As long as closure


30


holds compartment


20


in a closed position, the flexible rod


22


is contained. Disengagement of closure


30


allows compartment


20


to open about its hinge, thereby releasing flexible rod


22


. Flexible rod


22


is mounted within compartment


20


in such fashion as to insure that flexible rod


22


extends upwardly from the compartment


20


, above the head of the skier


12


. Compartment


20


may also be a soft-sided compartment constructed of durable fabric. In this embodiment, closure


30


serves to close an opening formed in the perimeter of compartment


20


. Said opening is of sufficient dimension to permit rapid deployment of flexible rod


22


as herein described upon release of the closure


30


which holds the compartment


20


in the closed position.




Within compartment


20


is stored a flexible rod


22


in a coiled configuration


26


. The proximal end of the flexible rod


22


is secured to the inside of the compartment


20


, while the distal end is provided with a flag


24


, preferably of a weatherproof material with a high visibility pattern or color. Flexible rod


22


is comprised of a tough yet resilient weatherproof material which may be fiberglass reinforced plastic, carbon fiber reinforced plastic, or any of a wide variety of spring steel alloys. The inner dimensions of compartment


20


are selected to accommodate the coiled rod


26


, which is the condition of the rod in the “stored” state. Release of closure


30


permits the rear of the compartment


20


to partly separate from the front of compartment


20


allowing flexible rod


22


to deploy once the retaining forces of the walls of compartment


20


have been relaxed by release of the closure


30


. This results in the flexible rod


22


extending to its full length in a whip-like fashion, thereby elevating the rod


22


and its associated flag


24


above the height of the top of the compartment


20


and above the head of the skier


12


.




In operation, assuming that the user of the invention has fallen or is otherwise in need of retrieval, the user grasps the handle


36


and pulls, thereby opening the closure


30


of compartment


20


allowing coil rod


26


to extend to full length.




Once the individual has been retrieved, or it has been otherwise determined that it is no longer necessary for the signal device to be deployed, the flexible rod


22


can be coiled, by hand, into the coiled configuration


26


and again stowed inside compartment


20


by virtue of closure


30


. This design allows for reuse. As can be appreciated from an examination of

FIG. 2

, it is possible to design the assembly


10


to be permanently affixed to a flotation device


14


or, in the alternative, to be removably affixed to such device.




In an embodiment of the invention as shown in

FIG. 3

, rod


22


is provided with a plurality of flags


24


spaced apart along the length of rod


22


, and offering even greater visibility than that provided by a single flag


24


.




In yet another embodiment of my invention, closure


30


may be designed to operate automatically upon contact with the closure


30


with water


18


. In this embodiment, a single catch serves to prevent the opening of compartment


20


. This catch is in the form of a spring-loaded element which is maintained in the closed or locked position by a water soluble pellet. In this embodiment, even if the user of the invention is unconscious or otherwise incapacitated, contact between the water soluble pellet and water results in the immediate dissolution of the pellet and release of the catch, thereby releasing the closure and permitting the coiled rod


26


to be extended into straight rod


22


as above described.




It will be readily apparent to those skilled in the art that the invention may likewise have utility in use by hunters, skiers and outdoorsmen who wish to be able to provide a rapidly deployable visible signal of their presence, for example, in high grass or deep snow. The invention may be fitted to a garment in the same fashion as it is fitted to a flotation vest as above described. In all other aspects, use and deployment of the invention is identical to its use and deployment in a marine setting as above described.




While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, the invention is not limited to those disclosed embodiments. To the contrary, the Applicant intends that this disclosure cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims, which scope is intended to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures as is permitted under the law.
