1. The Field of the Invention
This invention relates to hydration systems for providing fluids like water upon demand to a user.
2. The Relevant Technology
Personal hydration systems range from what could be regarded as the well known canteen (See one new example in U.S. Des. Patent No. 187,112 (Allenbach)) to bottles to bladders carried on the back of the user much like a back pack; See U.S. Pat. No. 6,032,831 (Gardner, et al). In some versions, a tube extends from the back of the pack to the front with a bite valve on its end which the user places in his/her mouth and operates by biting upon the valve to open and close it. See U.S. Pat. No. 6,039,305 (Hoskins, et all). While retention of the bite valve in the mouth is preferred, some users find it uncomfortable or inconvenient to retain it in the mouth particularly when involved in vigorous exercise or activity. Thus, the bite valve is sometimes removed after use and when so removed is coated with saliva so that contaminants may easily attach to it.
In some known systems, the bite valve out of the mouth is free to move about substantially unrestrained. Examples can be seen in U.S. Pat. No. 6,497,348 (Forsman). Thus in use the bite valve when removed from user's mouth, hangs free, allowing it to bounce or touch the user's clothing. Of course, if and when allowed to swing free, the bite valve can contact other persons, plants, the ground or other substrates or things that can contaminate the bite valve. In other circumstances, the bite valve may become entangled in equipment such as bicycle cables or trapped between the seat and gas tank of a motorcycle, which may separate the valve from the tube and thus unintentionally empty the contents of the hydration system. In such cases, the safety of the user may be compromised by a lack of restraint of the bite valve.
Thus it is desirable that systems be available to hold the bite valve when not in use. Schemes to effect such restraint have been ineffective in holding the bite valve. Clips, clamps, hook and pile connectors and the like have been suggested which all require user manipulation of something mechanical to effect connection or disconnection. However, taking the time and attention to refasten a bite valve to its securing means can have disastrous consequences for activities that require utilizing both hands at all times (e.g. rock climbing, extreme downhill skiing, motocross, kayaking, etc.).
Hence, a hydration system that is not truly a “hands free” system may be dangerous to operate under conditions where a user cannot manually reattach the bite valve to its holding system. Accordingly, there is a need for an improved arrangement to hold the bite valve and reduce its exposure to contamination and/or entanglement. Such an improved arrangement should be easy to operate and not require user manipulation to effect restraint.
A hydration system provides liquid to a user upon demand. The system includes a support means for removable attachment to the body of a user. A support means can be back pack, a waist belt or other system or structure to removably affix the hydration system to the body so that it is available for a wide range of suitable applications and in performing a wide range of action. The support means has a front portion, such as, for example, the belts or straps of a back pack, for positioning proximate the front or mouth of a user.
The desired hydration system also has container means for retaining fluid therein. Any suitable container configured to retain liquid and configured to be carried by a user is within contemplation. However, the bladder versions depicted are preferred for cost and convenience. The container means is associated with and supported by said support means. Desirably, the support means is some kind of pack structure configured to hold and retain the container means.
The container means has at least one fill-port means arranged for transmitting fluid into and desirably out of the container means. The container means also has a separate discharge port means for transmitting said fluid out of the container means. Also included is transmission means for transmitting the fluid from a proximal end through a length to a distal end. The proximal end is connected to the discharge port means for receiving the fluid from the discharge port means for communication or transmission through its length to its distal end. Bite valve means is connected to the distal end of the transmission means and is configured for positioning in the mouth of the user and operable by biting thereon. It is configured to be operable between a first closed position inhibiting the flow of fluid there though and a second open position in which the fluid passes there through.
The preferred system also includes retaining means for removably retaining the bite valve means to the front portion of the support system. The retaining means has a first element attached to the front portion and a second element attached to the bite valve means. The bite valve out of the user's mouth is movable between a stored position in which the first element and said second element are attracted toward each other and attached and a free position in which the second element is detached from the first element.
In a preferred configuration, the support system is a pack, which may be back pack, a fanny pack or any other pack device for attachment to and/or suspension from and on the body of a user. The container means may be a canteen or preferably a bladder sized to be positioned in the back pack.
Most preferably, the first element of the retaining means is a first magnet and the second element is a second magnet, selected to be attracting toward or with the first magnet. When the bite valve is allowed to swing free the second magnet attached thereto and the first magnet are attracted toward each other such that the first magnet attaches to the second magnet when in proximity. The distance in which the magnetic force is sufficient to attract the first magnet toward the second magnet will vary based on the strength and size of the magnets. Magnets may be selected to have a magnetic field to attract one to the other when spaced apart a distances from up to about 1 inch to about 4 inches. More desirably, the first magnet and the second magnet are selected to be cylindrical in shape and most desirably are rare earth magnets.
In desired configuration, the transmission means is a discharge tube having a length selected to extend over the shoulder of the user to position its distal end proximate the first magnet for movement into the stored position.
In preferred personal hydration systems, the bite valve has a housing and a sleeve sealingly and rotatably positioned in said housing. The first mange is attached to the housing. Preferably, the sleeve includes a head having an aperture. A tooth assembly for positioning in the mouth of the user is inserted into the aperture of the head. Desirably the sleeve is rotatable relative to the housing.
In alternate configurations, the support system is a back pack with a strap that extends over the shoulder. The strap has a length to extend along the front of the body for further extension along the torso toward the back and for reconnection to the back pack. The first element includes a buckle attached and movable along the length of the strap most preferably to a location, so that when the bite valve is not in the user's mouth, it can hang down along the user's front with the bite valve magnetically attaching to the buckle so that the user need not use any hands to effect the attachment.
The buckle desirably includes top belt receptacle and bottom belt receptacle each configured to slidingly receive the strap. Most preferably, each buckle has a perimeter and a first slot extending from the perimeter to the top belt receptacle, and a second slot extending from said perimeter to said bottom belt receptacle. The first slot and second slot both are sized to receive said strap there through. Thus, the buckle can be easily attached to and removed from the strap.
These and other objects and features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.
To further clarify the above and other advantages and features of the present invention, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It is appreciated that these drawings depict only typical embodiments of the invention and are therefore not to be considered limiting of its scope. The invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
While the user is not illustrated or depicted, the typical user is a human to whom the hydration system attaches. However, it is within contemplation that the hydration system 10 could be attached to different animals who may be trained to operate a bite valve which may be reconfigured for use by an animal.

The pack 12 also includes a chest strap 45 that is optional but preferred, which attaches by suitable clips or connectors to and extends between the left strap 40 and the right strap 42 to hold the left shoulder support 22 and the right shoulder support 44 in alignment and hold them in place.
The bladder 14 is here shown in cut-away. It is positionable in the pack 12 through the zippered opening 58. Of course once in the pack 12, the bladder 14 is fully supported. Other arrangements for supporting a container means like the bladder 14 in or on the pack 12 may be used including hooks, hook and pile connectors and a pouch. The nature of the connection or retention is limited only to those that allow the container means to discharge the liquid upon demand.

The first element is here shown to be a first magnet 80 attached to a buckle 82. The buckle 82 is mounted to the right shoulder support 24 and more particularly the right shoulder strap 42. The second element is also a magnet 84 mounted to the housing 86 of the bite valve 20. With the bite valve 20 removed from the user's mouth and in a free position, it should fall toward the user's waist retainer 44 and proximate the buckle 82. The first magnet 80 and the second magnet 84 are selected to have a magnetic force of attraction so that the second magnet 84, when proximate the first magnet 80, moves toward and attaches to the first magnet 80 thereby placing the bite valve 20 in a stored or fixed condition and keeping the discharge tube 18 from becoming entangled with an impediment. Accordingly, a user's hands are free to concentrate on and engage in an activity, and not placing the bite valve in a stored or fixed condition when not in the user's mouth.
The magnetic force of the magnets 80 and 84 may be selected in different magnitudes (gauss) such that the magnetic force is sufficient to attract one to the other when the magnets are a pre-selected distance from each other such as 1 inch, 2 inches, 3 inches and 4 inches.
In use, the user may place the bite valve 20 in the user's mouth and by biting on the bite valve 20, causing it to go from a closed position inhibiting fluid flow to an open position to allow fluid to flow. When done, the user may remove the bite valve 20 and allow it to drop into general alignment with the buckle 82 so that the magnets attract one to the other and place the bite valve 20 in a stored position so that a user is not required to manually make the connection. Discharge tube 18 and bite valve 20 are no longer free to swing about and into contact with clothing, other people, the ground, bushes and trees and another material or become dangerously entangled in equipment such as bicycle spokes and motorcycle wheels, gas tanks and handlebars.
To replace the bite valve 20 in the user's mouth, the user need only grip the proximal end 76 of the discharge tube 18 and pull it and the bite valve 20 apart so that the user may place the valve in the user's mouth to operate the bite valve to extract the fluid 16. The fluid may be any suitable or desired fluid such as water, or a similar hydrating fluid such as sport drinks, energy drinks, juices or the like.

It should be understood that other forms of bite valves may be used along with any suitable discharge tube. In addition, other magnets may be used so long as they provide sufficient force to hold the bite valve in place against the buckle or other suitable structure, so that a user is not required to use manual manipulation to bring the bite valve in close proximity with the buckle to facilitate the action of the force.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
