The Patent Description & Claims data below is from USPTO Patent Application 20070287598, Jaw stretching device.

1. A jaw stretching device, comprising: a base arm including a mouthpiece end and a connection end opposing the mouthpiece end, a piston channel being formed through the base arm between the connection end and the mouthpiece end; a first mouthpiece attached to the base arm at the mouthpiece end, the first mouthpiece being shaped to fit a curvature of teeth; a lever arm including a first and second end, the first end being connected to the connection end of the base arm, the lever arm being capable of rotating relative to the base arm about the connection end; a piston arm including a pivot end, an attachment end, and a length positioned between the pivot end and the attachment end, the length having a curved pattern, the piston arm being positioned in the piston channel, the curved pattern of the length being configured to slide through the piston channel, the second end of the lever arm being attached to the pivot end of the piston arm, the piston arm being capable of rotating relative to the lever arm about the pivot end; and a second mouthpiece attached to the piston arm at the attachment end, the second mouthpiece being shaped to fit the curvature of teeth.

2. The device of claim 1, further comprising a spring arranged to force the base arm and lever arm apart.

3. The device of claim 1, further comprising a limit structure, the limit structure being arranged to limit movement of the piston arm relative to the base arm.

4. The device of claim 1, further comprising a guide mechanism, the guide mechanism being designed to direct motion of the piston arm along a predetermined path.

5. The device of claim 4, wherein the guide mechanism includes guides formed on at least one side of the piston arm and a travel pin disposed on the base arm, the travel pin being arranged to slide in the guide as the piston arm slides through the piston channel.

6. The device of claim 5, wherein the second end of the lever arm is attached to the pivot end of the piston arm with a pivot pin, the lever arm further including a pin channel, the pivot pin being positioned in the pin channel and being capable of sliding in the pin channel as the travel pin slides through the channel on the piston arm.

7. The device of claim 1, further comprising a cushion disposed along at least one of the lever arm and the base arm to provide a grip for a user.

8. The device of claim 1, further comprising a sliding marker disposed on the piston arm, the sliding marker being configured to mark a position on the piston arm relative to a distance between the first mouthpiece and the second mouthpiece.

9. A jaw stretching device, comprising: a base arm including a mouthpiece end and a connection end opposing the mouthpiece end, a piston channel being formed through the base arm between the connection end and the mouthpiece end; a lever arm including a first and second end, the first end being connected to the connection end of the base arm, the lever arm being capable of rotating relative to the base arm about the connection end; a piston arm including a pivot end, an attachment end, and a length positioned between the pivot end and the attachment end, the piston arm being positioned in the piston channel, the second end of the lever arm being attached to the pivot end of the piston arm, the piston arm being capable of rotating relative to the lever arm about the pivot end; and a first mouthpiece is attached at the connection end of the base arm and a second mouth piece is attached at the attachment end of the piston arm with clip sockets, one clip socket being placed between the first mouthpiece and the base arm, and another clip socket being placed between the second mouthpiece and the piston arm, the first and second mouthpieces being capable of being removed from the clip sockets.

10. The device of claim 9, wherein the clip sockets include side openings and the first and second mouthpieces include clips, the clips being arranged to engage the side openings of the clip sockets when one of the first and second mouthpieces is inserted into the clip socket.

11. The device of claim 9, wherein the first mouthpiece has a different length than the second mouthpiece, the mouthpieces being attached to accommodate a user with variation in their bite.

12. A jaw stretching device, comprising: a base arm including a mouthpiece end and a connection end opposing the mouthpiece end, a piston channel being formed through the base arm between the connection end and the mouthpiece end; a first mouthpiece attached to the base arm at the mouthpiece end, the first mouthpiece being shaped to fit a curvature of teeth; a lever arm including a first and second end, the first end being connected to the connection end of the base arm, the lever arm being capable of rotating relative to the base arm about the connection end; a piston arm including a pivot end, an attachment end, and a length positioned between the pivot end and the attachment end, the piston arm being positioned in the piston channel, the second end of the lever arm being attached to the pivot end of the piston arm, the piston arm being capable of rotating relative to the lever arm about the pivot end; a second mouthpiece attached to the piston arm at the attachment end, the second mouthpiece being shaped to fit the curvature of teeth; and a binding structure arranged to hold the first mouthpiece spaced apart from the second mouthpiece.

13. The device of claim 12, wherein the binding structure includes a limit screw attached between the base arm and the lever arm, the limit screw being arranged to abut against one of the base arm and lever arm to adjust the space between the first and second mouthpieces.

14. The device of claim 13, further comprising a compression band attached to the lever arm and the base arm, the compression band being arranged to force the lever arm and base arm together.

15. The device of claim 12, wherein the binding structure includes a control screw attached between the base arm and the lever arm, the control screw being arranged to adjust the space between the first and second mouthpieces when the control screw is rotated in one direction to force the base arm and lever arm apart and when the control screw is rotated in another direction to force the base arm and lever arm together.

16. The device of claim 12, wherein the binding structure includes a set of notches formed into the piston arm, and further comprising a limit clip capable of being attached to the piston arm at a notch in the set of notches, the limit clip being attached in a position to limit movement of the piston arm through the base arm, the position corresponding to the space between the first and second mouthpieces.

17. The device of claim 12, wherein the binding structure includes a ratchet system placed between the piston arm and the base arm to adjust the space between the first and second mouthpieces.

18. The device of claim 17, wherein the ratchet system includes a set of notches formed in the piston arm and a ratchet clip attached to the base arm, the ratchet clip being arranged to insert into a notch of the set of notches and move to another notch in the set of notches in one direction along the piston arm to hold the space between the first and second mouthpieces.

19. The device of claim 12, wherein the binding structure includes a spring arranged to force the base arm and lever arm apart.

20. The device of claim 12, wherein the binding structure includes a set of sockets formed in the piston arm and a set pin, the set pin being selectively placed in one of the sockets to hold the space between the first and second mouthpieces.
