Definitions

  • the present disclosure relates to personal hydration reservoirs.
  • Adequate hydration is critical in maintaining the body's homeostasis. Maintenance of adequate hydration becomes both more important and more difficult as the duration of a strenuous physical activity increases.
  • Various techniques have been employed to maintain hydration during activity. The most common are pre-hydration, in which an athlete consumes large quantities of fluids before starting an activity, and carrying additional fluids in some external container.
  • pre-hydration is of limited utility. Since consumption of excessive quantities of fluid may cause bloating, nausea, and hyponatremia, an athlete often cannot pre-hydrate sufficiently to avoid dehydration during extended strenuous activity. Unless a reliable source of hydration is readily available, dehydration and loss of performance will occur.
  • An athlete may carry a much greater volume of fluids in external containers than may be comfortably consumed in a short period of time, allowing the athlete to rehydrate more or less continuously for the duration of an activity.
  • the quantity of fluids available for hydration is limited only by what the athlete is willing to carry.
  • Fluids are relatively heavy and change shape and shift position easily in response to motion and pressure. Since most athletes find it awkward and tiring to carry more than very small fluid containers by hand while active, a preferred method for carrying fluids relies on a backpack that holds one or more watertight containers.
  • a variety of personal hydration systems have evolved to fill this need.
  • a popular personal hydration system takes the form of a small, frameless backpack.
  • the backpack contains hydration system components and usually additional space for personal items such as clothing, food, and first aid supplies.
  • Typical hydration system components are a flexible plastic reservoir with a one to three liter capacity; a hose, one end communicating with the reservoir and the other end closed by a bite valve; and a fill cap or roll top as a means for fluid to enter and fill the reservoir.
  • the hydration system components are integrated into the small backpack to ease their removal for cleaning and re-filling.
  • the hydration reservoir is located in a dedicated compartment behind the surface of the backpack that contacts the user's back. This compartment keeps the backpack's contents separate from the reservoir and keeps the pack contents dry and further protects the reservoir from accidental puncture.
  • the reservoir compartment also holds the weight of the fluid-filled reservoir closer to the individual's center-of-mass, thus enhancing balance and stability.
  • the reservoir when the reservoir is filled with fluid it assumes a columnar or semi-cylindrical shape in response to internal fluid pressure. Since most personal hydration systems are designed to accept a semi-cylindrical reservoir, this shape fits most hydration systems. However, the reservoir's columnar or cylindrical shape forces the reservoir away from user's back and thus away from his or her center-of-mass, creating a tendency for the pack to roll from side-to-side in response to changes in direction by a user.
  • Hydration packs therefore often incorporate load control features designed to arrest this motion, adding weight and expense in the form of straps, connectors and fabric. Taken together with the dedicated reservoir compartment these load control features can greatly increase the difficulty of installing and removing a reservoir for cleaning and filling.
  • a reservoir attachment system that secures a reservoir within a pack while allowing quick removal and installation would provide a significant benefit for hydration pack users. Disclosure of Invention
  • I provide an apparatus for temporarily attaching a fluid reservoir to a backpack.
  • the fluid reservoir has a bladder, a handle, an orifice for filling the bladder, a cap for sealing the orifice, a tube for withdrawing fluid from the bladder, and a bite valve to control fluid flow from the tube.
  • the handle is attached to the bladder at an upper handle end and a lower handle end.
  • a central portion of the handle arches away from the bladder between the upper and lower ends of the handle.
  • the central portion of the handle is wider than the upper and lower ends of the handle.
  • the backpack contains a reservoir compartment with an hourglass-shaped frame secured within.
  • the frame is a loop of stiff material with a wide upper lobe, a wide lower lobe, and a narrow frame waist disposed between the upper lobe and the lower lobe.
  • the lower end of the handle is narrower than the frame waist.
  • the central portion of the handle is wider than the narrowest portion of the frame waist.
  • the fluid reservoir may be at least partially inserted into the reservoir compartment so that the handle passes through the upper lobe of the frame and within the frame waist until the narrowest portion of the frame waist is disposed between the bladder and the handle, effectively securing the handle within the frame and discouraging the reservoir from shifting or rolling in response to movement of the pack.
  • the frame may be attached directly to the pack or contained within a frame sleeve within the reservoir compartment, the frame then forming a reservoir attachment slot within the frame sleeve.
  • a reservoir support strap may attach to the reservoir to support at least a portion of the weight of the fluid reservoir.
  • the edges of the handle may curve away from the bladder to facilitate insertion of the handle within the frame.

  • a hydration backpack may be equipped with a simple and effective fluid reservoir attachment system in which a reservoir structure easily engages a structure on the pack to hold the reservoir securely in place.
  • Fig. 1 shows a perspective view of an elongated, flexible fluid reservoir 100 with a handle 110 shaped to engage a tapered slot within a hydration backpack.
  • the reservoir 100 includes a collapsible bladder 102, the handle 110, an orifice and cap 108, a tube 104, and a bite valve 106.
  • the bladder 102 is made of flexible plastic sheets welded together at the edges. Fluids within the bladder 102 may be withdrawn through a tube 104 that is opened or closed by the bite valve 106.
  • the bladder 102 may be emptied or filled through the orifice (not visible) that sealed by the cap 108.
  • the lower end 116 and the upper end 118 of the handle 110 are attached to the bladder 102 near opposite ends of the bladder 102.

  • a reservoir attachment slot 504 is formed into the rear wall 518 of the reservoir compartment 502 by the frame 200 (in broken lines).
  • the frame waist 206 gives shape and some rigidity to the rear wall 518 to create a slot rim 516 on either side of the reservoir attachment slot 504.
  • the reservoir 100 (for clarity, shown without the tube 104 and bite valve 106) may be easily and securely attached to the hydration backpack 500 by orienting and inserting the reservoir 100 into the reservoir compartment 502 so that the lower end 116 of the handle 110 slides into the reservoir attachment slot 504. As the handle 110 slides down into the reservoir attachment slot 504, the narrow lower end 116 of the handle 110 and the transverse cross-sectional curve of the handle 110 allow the edges 114 of the handle 110 to pass freely between the opposing sides of the slot rim 516 within the reservoir attachment slot 504.
  • the end-to-end arch of the handle 110 allows the edges 114 of the central portion 112 of the handle 110 to project and slide behind the slot rim 516.
