Variable force mouth exerciser
View Patent ↗The invention described herein relates to a mouth exerciser for providing a variable resistive force against which a user may exercise their mouth and jaw muscles. The apparatus may be selectively configured between a plurality of resistive force settings, thereby enabling a user to adjust their exercise routine as desired. The mouth exerciser may be particularly adapted to fit the topography of a particular user's oral cavity and may be easily disassembled for storage and transport.
1. An apparatus for strengthening a jaw, the apparatus comprising:
a pair of mouthpieces, each mouthpiece comprising a first end, a second end, and an arcuate extent therebetween, each mouthpiece further comprising upper and lower surfaces, the lower surface being substantially flat and the upper surface including a pair of raised ridges extending from the first end to the second end;
a pair of mouthpiece trays, each mouthpiece tray having a first end, a second end, and an arcuate extent therebetween, each mouthpiece tray further comprising upper and lower surfaces, the lower surface being substantially flat and the upper surface including a pair of raised edges extending from the first end to the second end, each mouthpiece tray receiving a corresponding mouthpiece, wherein the lower surface and the raised ridges of each mouthpiece are frictionally engaged to the upper surface and the raised ridges of each mouthpiece tray, thereby holding each mouthpiece in place;
a pair of connector plates, each connector plate having a first end and a second end, the first end of each connector plate connected to the lower surface of one of the mouthpiece trays and the second end of each plate including an aperture;
a primary tension coil having a first end, a second end, and a coiled extent therebetween, each end including a pin, each pin removeably positioned through the aperture of the corresponding connector plate, at least a portion of the second end of the primary tension coil including a pair of grooves formed along its length, the primary tension coil having first and second orientations, the first orientation having a greater distance between the first and second ends than the second orientation, the primary tension coil biased in the first orientation;
a pair of secondary tension coils having a first end, a second end, and a coiled extent therebetween, each secondary tension coil positioned adjacent the primary tension coil and having first and second orientations, the first orientation having a greater distance between the first and second ends than the second orientation, the secondary tension coils biased in the first orientation;
a rectangular tension plate fixedly connecting the first ends of the primary and each secondary tension coil; and
a tension adjustor having a primary aperture and a pair of secondary apertures, the primary aperture slidably received by the second end of the primary tension coil and including a pair of detents engaging the grooves of the primary tension coil, the tension adjustor having a first orientation and a second orientation, wherein in the first orientation the tension adjustor engages only the second end of the primary tension coil, and wherein in the second orientation the tension adjustor further engages the second ends of the secondary tension coils.
2. The apparatus as described in claim 1 , wherein the mouthpieces are molded to a user's mouth.
3. The apparatus as described in claim 1 further configured to be disassembled for ease of storage.
