DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

(6) As illustrated in FIG. 1, a system constructed in accordance with the principles herein is shown generally at 100. The system is suitable for use in a cushion, pillow, or any other suitable device. The system 100 includes a first chamber, or first reservoir compartment, 110. The first chamber 110 is connected to a second chamber, or second reservoir compartment, 120 via a selective control mechanism 130. The selective control mechanism 130 selectively enables opening and closing of at least one portal 250 of the system 200, as shown in FIG. 2.

(7) The first and second chambers 110, 120, respectively, are prefilled with a suitable fill material 140, and sealed to form closed chambers. The selective control mechanism 130 is connected to the first and second chambers 110, 120 so that fill material 140 can be selectively moved from the first chamber 110 to the second chamber 120 via the selective control mechanism 130.

(8) A system 100 constructed in accordance with the principles herein provides ergonomic/orthopedic improvements on adjustable pillows, by utilizing extended compartments which act as reservoirs for filling.

(9) In an embodiment, portal 250 can be fitted with an elastic assembly 260, as illustrated in FIG. 2D. The elastic assembly can include a bungee cord 265, a lock 270 provided on the bungee cord 265, an inlet 275 and an outlet 280 for threading the bungee cord 265 through a cover 285 of the system 200. The inlet 275 and outlet 280 can be sealed using any suitable mechanism, such as, for example, grommets 290 applied to the cover 285. Alternatively, as shown in FIG. 3, portal 350 can include a fully internally located selective closing mechanism 330, such as, for example, magnets, Velcro, an internal elastic or bungee, or any other suitable mechanism for selectively connecting a first chamber 310 and a second chamber 320 of the system 300.

(10) In yet another embodiment, a portal of the system can be selectively operated by a fully external selective control mechanism, such as, for example, a clamping device, a fabric tie, or any other suitable mechanism.

(11) Portal 250 can open and shut internally to allow the user to re-distribute filling until the pillow is the correct circumference for their individual tastes, without having to open the system 200 in order to adjust the firmness of the system 200.

(12) Advantageously, a system constructed in accordance with the principles herein is much simpler to operate than other adjustable systems, such as adjustable pillows. The system is a self-contained unit with an internal mechanism of operation. The system does not require the use of pumps/does not need to be blown up or deflated. The system can be utilized in a number of settings and positions. The system can include a variety of filling materials, such as, for example, absorbent filling. Absorbent filling is advantageous over the use of buoyant pneumatics encased within plastic or rubber. The system will adjust for a broader range of users' shapes and sizes, conforming to fit more naturally. The system can be configured to either alleviate undesired pressure, or provide increased resistance. The system makes use of existing surface area to alleviate undesired pressure and achieve a desired firmness.

(13) As illustrated in FIGS. 3A-3D, a system shown generally at 300 constructed in accordance with the principles herein can include a one-piece, self-contained unit with a main reservoir compartment, or chamber 310 in the center, and two relief reservoirs, or chambers 320 on either side of the chamber 310. The pillow can have a U shaped curve, and be filled with a suitable fill material, such as, for example micro beads, 335 as shown in FIG. 3B.

(14) The system 300 can include an outer shell 340 formed of one or more suitable materials, such as, for example, microfiber. Between the main chamber 310 and side reservoirs 320 is a portal 350, shown in more detail in FIG. 3D, which allows for the fill material 335 to be distributed from one compartment, or chamber, to the next. Finger-sized webbing loops 360 on either side of the system 300 can oppose one another, to serve as handles for opening the portal 350. In an embodiment, hook and loop fasteners can be used internally to selectively close the portal 350. Alternatively another suitable internal device, such as, for example, elastic as illustrated in FIG. 3D can be used to selectively close the portal 350. Webbing loops 360 can then be pulled apart, separating hook and loop fasteners and opening the portal 350. Once portal 350 is open, filling 335 is able to flow from one compartment to the next.

(15) A non-adjustable area 370 between the reservoirs can also be filled with a suitable fill material, such as, for example, micro beads, if desired.

(16) Once portal 350 has been opened, filling can be distributed amongst the reservoir compartments 320, allowing the circumference of the pillow to adjust for the user's desired level of resistance, or firmness.

(17) In yet another embodiment constructed in accordance with the principles herein, a system shown generally at 400, in FIGS. 4A and 4B includes chambers, or reservoir compartments 410 formed in a straight cushion, such as, for example, a pillow body. The sectional view illustrated represents an internal view of the three reservoir compartments, including a main reservoir 420 and the reservoirs 410 horizontally bisecting the upper and lower halves of the system 400.

(18) The side reservoir compartments 410 can be emptied and all of filling material, or filling 430 can be moved to rest within the main reservoir compartment 420 without having to readjust the material from inside the system 400. The movement of the filling 430 to the main reservoir 420 results in an overall increase in circumference of the main reservoir 420, thereby adjusting the firmness of the compartment. Portal 440 is then closed maintaining full circumference of the system 400.

(19) FIG. 4B further illustrates that the side reservoir compartments 410 are full, and filling 430 has been distributed throughout the body of the system 400. This results in an overall decrease in circumference of the main reservoir 420. Portal 440 is open, which allows filling 430 to be re-distributed at will throughout the system 400.

(20) A few exemplary alternative embodiments constructed in accordance with the principles herein include the following modifications: a) an expandable/adjustable outer shell which allows for filling to be packed looser or tighter; b) portals between reservoir compartments can remain slightly open at all times; c) materials such as elastic or magnets can be used to open/close portals; d) buttons or a draw-string assembly can be used to open/close portals; e) varying the size of main cushion body and reservoirs to allow for greater range of anatomical support; f) reservoir extensions can be rotated to accommodate ergonomic needs of user; g) a straight cushion body; h) varying a shape of the system main reservoir and side reservoirs; i) varying handles for portal opening to allow for varied size pulls; j) system stuffed with a varying range of fillings to allow for multiple instances of therapeutic application; k) an outer shell comprised of a number of different materials; l) a pillow including a non-prefilled reservoir; and m) increasing or decreasing the number of reservoirs.

(21) As illustrated in FIG. 5, a method of adjusting fill material volume between chambers in a fixed, closed system, shown generally at 500, according to the principles herein can include the following steps. First, a first chamber is prefilled with a fill material at 510. Next, a second chamber is prefilled with the fill material at 520. The first and second chambers are sealed to form the closed system at 530. A selectively operable system is inserted between the first and second chambers at 540. The fill material is selectively movable by selective operation of the selectively operable system to adjust the firmness of the chambers of the system at 550.

(22) In accordance with the principles herein, the term fixed, pre-filled chamber of the system is defined by a chamber that is pre-filled and sealed, and where once sealed, no additional fill material can be added to the system from outside the system.

(23) While the exemplary embodiments of the present disclosure are presently considered to be preferred, various changes and modifications can be made without departing from the spirit and scope of the principles disclosed herein. The scope of the principles disclosed herein is indicated in the appended claims, and all changes that come within the meaning and range of equivalents are intended to be embraced therein.
