ATTORNEYS United States Patent Ofice 3,434,470 Patented Mar. 25, 1969 3,434,470 SNORE INHIBITING DEVICE James C. Strickland, 181 Walter Hays Drive, Palo Alto, Calif. 94303 Filed May 27, 1966, Ser. No. 553,332 Int. Cl. A61f 5/56 US. Cl. 128136 6 Claims ABSTRACT OF THE DISCLOSURE This invention relates to an oral device used to prevent snoring and, more particularly, to such a device adapted to be fitted on the upper teeth.
The invention resides in a plate adapted to be positioned within the mouth and in the U-shaped space defined by the upper teeth. The plate has mounting structure which releasably grips the upper teeth so that the plate is removably maintained in this space. In this position, the plate considerably reduces the effective volume of the air flow passage through the mouth. Thus, less air can flow through the mouth in either direction. As a result, snoring is substantially eliminated since the snoring is a function of the volume rate of flow of air through the mouth. A portion of the air flow inhaled and exhaled must therefore be directed through the nose in bypassing relationship to the mouth, a condition which is to be desired to minimize snoring.
Snoring occurs when the uvula and the soft palate at the back of the mouth vibrate in response to the flow of air past these tissues. It has been reasoned that snoring will be minimized or eliminated if air flow through the mouth is inhibited. With this end in view, anti-snore devices in the past have generally been of a construction which completely blocks the air flow through the mouth. All inhaled and exhaled air thus has to travel through the nose so that the vibratory tissues which cause snoring remain substantially unaffected by the air flow.
The prior devices are not satisfactory because they are cumbersome in the mouth and are uncomfortable to the user. To be efiective, they must be custom made since teeth configurations vary between individual users. To reduce the size of the device to avoid discomfort would increase the danger of swallowing the device during use.
The present device overcome the disadvantages of the prior structures by providing a device of simple and rugged construction which is effective in minimizing or substantially eliminating a snoring condition even though it only partially restricts the air flow through the mouth. Thus, the desired result is attained without causing the user to sufier the discomfort which arises from completely blocking the mouth. The device also does not interfere with tongue movements and it is safe to use in that it cannot be swallowed nor can it cause harm to the teeth or gums. The device can be produced at minimum cost with readily available, inexpensive materials and through the use of well-known techniques. It can be used over and over again and can be easily sterilized for re-use. The device is adjustable so that it can fit in the mouths of different individuals and can be used by children as well as adults.
It is therefore the primary object of this invention to provide an oral device to prevent snoring wherein the presence of the device within the mouth reduces the volume of the effective air passage therethrough to reduce the volume rate of air flow through the mouth and thereby minimize the vibrations of tissues which generally cause a snoring condition.
Another object of the invention is to provide a device of the type described which does not cause discomfort to the user or harm the teeth or gums during use.
Another object of the present invention is to provide a device of the type described which is adjustable in size so that it can be used by different individuals having respective upper teeth mouth configurations.
A further object of the invention is to provide a snorepreventing device which is simple nad rugged in construction, is inexpensive to produce from materials rendering it usable over and over again, and is of a size which cannot be swallowed during sleep.
Other objects of this invention will become apparent as the following specification progresses, reference being had and to the accompanying drawing wherein:
FIG. 1 is a top plan view of the device;
FIG. 2 is a rear elevational view of the device looking in the direction oflines 22; and
FIG. 3 is a cross sectional view taken along line 33 of FIG. 1.
A preferred embodiment of the device is denoted by thenumeral 10 and includes a tooth-engaging member 12 to which aflat plate 14 is coupled.Member 12 is U-shaped to conform to the generally U-shaped configuration of the upper teeth and defines a pair of spaced, opposedsides 14 interconnected by abight 16.Sides 14 andbight 16 are formed from a yieldable material and are transversely U-shaped as shown in FIGS. 2 and 3 to define a tooth-receivinggroove 18 the width of which is such as to permitmember 12 to frictionally engage the upper teeth whendevice 10 is in the mouth. Thus,member 12 may be releasably positioned on the upper teeth with the front teeth in the portion ofgroove 18 defined bybight 16 and the side teeth in the grooved portions defined bysides 14.Member 12 has a construction similar to that of tooth protectors used in certain sports. Preferably, rubber or a suitable plastic material is used to formmember 12 to provide the yieldable characteristics therefor. The yieldability ofmember 12 will permit it to be fitted on various sets of teeth.
Plate 14 fills the U-shaped, planar space defined bysides 14 andbight 16. To provide for adjustability ofdevice 10,plate 14 has a pair of relativelyshiftable plate sections 20 and 22, which are connected tomember 12 and are disposed in overlapping relationship to each other. Each section has an arcuate outerperipheral edge 24 rigidly connected to the adjacent portion of the innerperipheral surface 26 ofmember 12. Eachedge 24 extends from anouter location 28 adjacent to thecorresponding side 14 to aninner location 30 as shown in FIG. 1. Acontinuation 32 of eachedge 24 is spaced inwardly fromperipheral surface 26 to allowmember 12 to be deformed sufiiciently to fit a particular set of upper teeth.
Edges 24 may be bonded by a suitable adhesive to member 12 or may be integrally secured thereto such as by moldingmember 12 andplate sections 20 and 22 in the same molding process. In either case,plate 14 effectively closes the space defined by the U-shaped configuration ofmember 12.
In use,device 10 is put into the mouth and placed on the upper teeth. Fitting of the device may be required and this can be accomplished by deforming or manipulatingmember 12 until it substantially conforms to the U-shaped configuration of the teeth. The overlapping, relatively shiftable feature ofplate sections 20 and 22, as well as the yieldability ofmember 12 permits this fitting to be accomplished.
Sincemember 12 frictionally engages the teeth, it cannot be dislodged during sleep. Moreover, it is sufficiently large that it will not be swallowed.
In its operative disposition,plate 14 reduces the volume of the air passage through the mouth and causes all inhaled air to pass beneath its under surface. This is becausesections 20 and 22 isolate the region aboveplate 14 with the region therebelow. Thus, any air above the plate must first pass downwardly about therearmost edges 34 ofsections 20 and 22 before it can be expelled from the mouth.
By reducing the volume of the air flow passage through the mouth, the volume rate of flow of air is reduced. Thus, a certain portion of air must pass into, through and out of the nose. Since snoring is a function of the total volume of air being inhaled and exhaled through the mouth, it follows that snoring will be minimized or substantially eliminated by this volume reduction in the mouth. This resistance to complete air flow through the mouth inhibits the build-up of resonant tissue vibrations which are the source of the snoring condition.
Device can also be used on denture plates as well as natural teeth. It can be used by children as well as adults and can be used over and over again without replacement. It is easily sterilized since plate sections and 22 can be separated slightly for cleaning purposes.
While one embodiment of this invention has been shown and described, it will be apparent that other adaptations and modifications can be made without departing from the true spirit and scope of the invention.
