said intermediate arch tray assembly being attached to said lower arch tray assembly so that said lower arch tray assembly moves with the user's lower set of teeth in a horizontal direction relative to each of said intermediate arch tray assembly and said upper arch trat assembly that is connected to said intermediate arch tray assembly, whereby to correspondingly adjust the position of the user's lower jaw relative to the position of the user's upper jaw.

2 . The jaw displacement oral appliance recited in claim 1 , wherein the second coupler at each of the pair of sides of said intermediate arch tray assembly includes a pair of pins that are axially aligned with one another to be received by and snapped into said interlocking engagement with the each of each of said first couplers.

3 . The jaw displacement oral appliance recited in claim 2 , wherein the catch of each first coupler has a laterally extending catch hole and the pair of axially aligned pins of each second coupler is received within said catch hole at which to be snapped into said interlocking engagement with said catch so as to prevent a separation of said upper arch tray assembly from said intermediate arch tray assembly.

4 . The jaw displacement oral appliance recited in claim 3 , wherein the pair of axially aligned pins of each second coupler are flexible so as to bend away from one another in order to accommodate the catch of each first coupler moving therebetween by which to enable each pair of pins to be received by said catch within the catch hole thereof.

5 . The jaw displacement oral appliance recited in claim 3 , wherein the catch hole of each first coupler is higher in a vertical direction than a cross section in the vertical direction of each of the pair of axially aligned pins of each second coupler received within said catch hole, such that said pair of pins are slidable vertically upward through said catch holes.

6 . The jaw displacement oral appliance recited in claim 2 , wherein each pair of axially aligned pins of said second couplers are separated from one another by a gap, and respective ones of the catches of said first couplers are configured to move through said gaps so that said pairs of axially aligned pin are snapped into said interlocking engagement with said catches.

7 . The jaw displacement oral appliance recited in claim 1 , wherein said lower arch tray assembly has a position adjustment block located at each of the pair of sides thereof and said intermediate arch tray assembly has a locking channel located at each of the pair of sides thereof, said position adjustment blocks being received within and slidable through respective ones of said locking channels when said lower arch tray assembly moves in said horizontal direction relative to each of said intermediate arch tray assembly and said upper arch tray assembly that is connected to said intermediate arch tray assembly.

8 . The jaw displacement oral appliance recited in claim 7 , wherein each position adjustment block and each locking channel located at each pair of sides of the lower and the intermediate arch tray assemblies has a set of teeth, the sets of teeth of said position adjustment blocks and said locking channels lying in meshing engagement with one another, whereby said lower arch tray assembly and said intermediate arch tray assembly are mated in releasable locking engagement with one another.

9 . The jaw displacement oral appliance recited in claim 8 , wherein said intermediate arch tray assembly is responsive to compressive squeezing forces being simultaneously applied to the pair of sides thereof to compress said intermediate arch tray assembly and thereby move the sets of teeth of said rocking channels out of their meshing engagement with the sets of teeth of the position adjustment blocks to enable said position adjustment blocks to slide through said locking channels and said lower arch tray assembly to move in said horizontal direction relative to each of said intermediate arch tray assembly and said upper arch tray assembly that is connected to said intermediate arch tray assembly.

10 . The jaw displacement oral appliance recited in claim 1 , wherein each of said upper, said intermediate and said lower arch tray assemblies has an arcuate configuration with a curved front that matches a bite pattern of the user's upper and lower sets of teeth.

11 . The jaw displacement oral appliance recited in claim 1 , wherein the pins of said second couplers located at each of the pair of sides of said intermediate arch tray assembly are snapped into said interlocking engagement with respective ones of the catches of said first couplers located at each of the pair of sides of said upper arch tray assembly to establish the hinges at which said upper arch tray assembly is rotated relative to said intermediate and said lower arch tray assemblies.

12 . The jaw displacement oral appliance recited in claim 1 , wherein said upper arch tray assembly that is pivotally connected to said intermediate arch tray assembly is unable to become separated and float free from said intermediate arch tray assembly when the user's mouth is opened during sleep.

13 . A jaw displacement oral appliance configured to be inserted in a mouth of a user to adjust the position of the user's lower jaw relative to the user's upper jaw so as to maintain an open airway to the user's throat through which the user can breathe while sleeping, said jaw displacement oral appliance comprising:

an upper arch tray assembly including an upper tooth impression liner configured to receive an upper set of teeth of the user's upper jaw during sleep, said upper arch tray assembly having an accurate configuration with a curved front and a pair of sides that are spaced from and lie opposite one another;

a lower arch tray assembly including a lower tooth impression liner configured to receive a lower set of teeth of the user's lower jaw during sleep, said lower arch tray assembly having an arcuate configuration with a curved font and a pair of sides that are spaced from and lie opposite one another; and

an intermediate arch tray assembly lying between said upper and said lower arch tray assemblies and having an arcuate configuration with a curved front and a pair of sides that are spaced from and lie opposite one another,

said upper, said intermediate and said lower arch tray assemblies lying one above the other, and said upper arch tray assembly having a first coupler located at each of the pair of sides thereof and said intermediate arch tray assembly having a second coupler located at each of said pair of sides thereof and being pivotally connected in interlocking engagement to respective ones of said first couplers to prevent said upper arch tray assembly from being sated from said intermediate arch tray assembly and to establish a hinge at which said upper arch tray assembly is rotated with the user's upper set of teeth through an angle relative to said intermediate and said lower arch tray assemblies such that said upper arch tray assembly pivots upwardly and away from said intermediate and said lower arch tray assemblies and the user's lower set of teeth when the user's month is opened during sleep,

wherein the first coupler that is located at each of the sides of said upper arch tray assembly is a catch having a catch hole formed therein and the second coupler that is located at each of the sides of said intermediate arch tray assembly includes a pair of pins that are axially aligned with one another and snapped into receipt by and into said interlocking engagement with said catch at the catch hole thereof so as to establish said hinge at which said upper arch tray assembly is rotated, said catch hole having a size that is higher in a vertical direction than a cross section in the vertical direction of said pair of pins to permit said pair of pins to move vertically through said catch hole and said upper arch tray assembly to correspondingly move up and down relative to said intermediate and lower arch tray assemblies when the user's mouth is opened and closed during sleep.

14 . The jaw displacement oral appliance recited in claim 13 , wherein each of the pair of pine of the second coupler that is located at each side of said intermediate arch tray assembly is flexible by which to cause said pair of pins to be snapped into said receipt by and said interlocking relationship with the catch at said catch hole thereof to establish said hinge.
