Anti-Snoring Apparatus

The present invention relates, in general, to neck collars and, particularly, to an anti-snoring device for maintaining almost erect the head of the sleeper so that the chin does not slump on the chest.

Snoring is a rough, hoarse noise produced by the vibration of air waves passing through a partially obstructed trachea. The trachea is the main trunk of a system of tubes through which air passes to and from the lungs. When the head is held erect, air passes through the trachea unimpededly. However, if the head and neck are flexed, the trachea also becomes flexed. There is then created, at the point of flexion, a point of partial obstruction. Air passing through this point of partial obstruction causes vibration which produce the unpleasent sound referred to as snoring. The trachea can become flexed when a person is sleeping. Such a condition can occur when the head of the sleeper droops and the chin rests on the chest. By elevating the chin away from the chest, the trachea is straightened and the problem is solved. The effectiveness of the principle of elevating the chin is demonstrated by the fact that in all life threatening situations involving asphyxia, this procedure is mandated as the first step before artificial respiration is to be administered. A further support of the theory is in drawing attention to the fact that no one snores when awake even if lying in bed; because when awake, the head subconsciously is kept elevated away from the chest by the pulley action of the muscles at the back of the neck. This control is relaxed during unconsciousness.

When the present theory embodied in this invention was first expressed, it was presented as a suggestion, without any critical study, that the ordinary flat cervical collar used for sprained necks might also serve as a device to keep the chin elevated. Subsequent observation soon demonstrated that the principle which determined the effectiveness of the flat collar in relieving the pains of a sprained neck, is diametrically opposite to that which would make an anti-snoring device useful. In the former, the intended purpose is primarily to restrict the movement of the head from side to side; since in neck sprains, downward movement of the head does not cause much pain. To be truly effective, the sprain collar must be wide enough to envelope at least the lower portion of the chin to immobilize the head. When this, however, has been attained, it is then easy for the chin to slip downwards between the edges of the enveloping collar and still rest on the chest, thereby militiating against its use as an effective and dependable anti-snoring device. In addition, such collars substantially restrict movement of the head and neck in all directions, and therefore are uncomfortable to wear and interfere with normal sleep of the wearer. Specifically, whereas it is the forward flexion of the cervical vertibrae that creates the restriction of the trachea leading to snoring, such existing collars contrastingly restrict side and back flexion of the neck unnecessarily.

Accordingly, the present invention has, as an object, the provision of an anti-snoring apparatus which maintains the chin markedly above the sleeper's chest.

It is a further object of the invention to provide a flexible anti-snoring apparatus.

Still another object of the invention is to provide an anti-snoring apparatus which is held securely around and under the neck and under the chin.

Yet, another object of the invention is to provide an anti-snoring apparatus which is simple to construct and reliable in its use.

A further object of the present invention is to provide such advantageous functions while not unduly or unnecessarily restricting other normal movement of the head or neck to thereby maximize the comfort and acceptability of the apparatus and permit normal sleep.

These and other objects of the invention will become apparent upon consideration of the accompanying specification and drawings.

The present invention comprises an anti-snoring apparatus for preventing a sleeping person from making snoring sounds.

The apparatus comprises a cylindrically shaped body which encircles a sleeper's neck. Because the apparatus is to be worn while sleeping, the cylindrical body has a cross-sectional diameter so calculated as to allow free side-to-side movements of the head, yet, prevent its downward flexion on the chest. The cylindrical body has a first and second end. Extending from each such end is a connecting cord keeping each such end in close proximity at the rear of the sleeper's neck. The apparatus is attached around the user's neck by straps. These straps maintain the cylindrical body, intermediate the first end and second end, beneath the user's chin. In one embodiment of the invention, neck straps are provided, which adjust to the diameter of the user's neck. In a second embodiment, head straps are provided which adjust to diameter of the user's head.

The apparatus is a flexible collar having a resilient core covered with a soft, absorbent fabric. The resilient core can be made from foam rubber and the soft fabric can be satin.

The attachment straps each has a first end attached to the cylindrical body. The second end of each strap has a hook-and-loop fastening material attached thereto. When the straps are attached together, the anti-snoring apparatus is maintained securely and comfortably beneath the user's chin.

Snoring is caused by the passage of air through a partially obstructed trachea. This can occur during sleep when the head slumps or droops on the chest. Therefore, an effective way to eliminate snoring is by elevating the chin from the chest. This must be done in a comfortable manner so as not to interrupt the sleeping person. The present apparatus allows free movement of the head and neck in all directions with the exception of downwards. Therefore, a person can comfortably sleep without disturbing others by snoring. The anti-snoring device will prevent the sleeper from snoring and not the snorer from sleeping.

While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail, several specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiments illustrated.

A preferred embodiment of the invention is shown in FIG. 1, where anti-snoring apparatus 10 has a cylindrically shaped body 11 surrounding the user's neck. The cylindrically shaped body 11 is covered by a soft fabric 12 so as not to irritate user's skin.

The rear elevational view of FIG. 2 shows cylindrically shaped body 11 in an unflexed position. Body ends 14a and 14b are held at the rear of user's neck by cord 13. Cord 13 attaches to body ends 14a and 14b by end connectors 15a and 15b. Because anti-snoring apparatus 10 must fit comfortably around user's neck, clasp 16 is provided to effectively adjust the length of cord 13.

The mid-point 17 of cylindrically shaped body 11 is maintained under user's chin by neck attachment straps 18a and 18b. Restraining bands 19a and 19b surround cylindrically shaped body 11 and secure neck attachment straps 18a and 18b thereto. Neck attachment straps 18a and 18b attach to each other at the rear of the user's neck by means of a hook-and-loop fastening method. A multiplicity of hooks 20 attach to neck attachment strap 18a and cooperate with a multiplicity of loops 21 attached to neck attachment strap 18b. The fastener can be adjusted to comfortably maintain mid-point 17 beneath user's chin.

In the top view of FIG. 3, cylindrically shaped body 11 is shown in a flexed position. This flexed position is maintained by attaching neck attachment straps 18a and 18b to each other, and effectively shortening cord 13. Body ends 14a and 14b do not join together directly at the rear of user's neck. Rather, they are connected by cord 13. This allows for more comfort in wearing of the anti-snoring device 10 while lying on the back and so does not prevent the user from sleeping.

FIG. 4 is an enlarged view of the fasteners attached to neck attachment straps 18a and 18b. The diameter of the user's neck will determine the overlap of the loop portion 21 with the hook portion 20.

The cross-sectional view of FIG. 5 shows soft fabric cover 12 surrounding foam rubber core 22 of cylindrically shaped body 11. The foam rubber core 22 will compress when user's head is moved, however, cylindrically shaped body 11 is non-collapsible and will prevent user's chin from contacting user's chest.

A second embodiment of the invention is shown in FIG. 6, where cylindrically shaped body 23 has head attachment straps 24a and 24b. The head attachment straps 24a and 24b are positioned behind the user's ears and attach to each other on top of the user's head.

The rear elevational view shown in FIG. 7 shows body 23 in an unflexed position. Cylindrically shaped body 23 has head straps 24a and 24b attaching to restraining bands 25a and 25b. Head straps 24a and 24b attach to each other across the top of the user's head by means of a hook-and-loop fastening means. A multiplicity of hooks 26 attached to head strap 24a, cooperate with a multiplicity of loops 27, attached to head strap 24b. Head straps 24a and 24b maintain midpoint 28 securely beneath the user's chin. Cord 29 attaches to body ends 30a and 30b by end connectors 31a and 31b and maintains body ends 30a and 30b at rear of user's neck.

Anti-snoring apparatus is constructed to be lightweight and comfortable to wear when sleeping. It allows free rotation of the user's head and does not immobilize the user's cervical vertebrae. The anti-snoring apparatus maintains a clear airway through user's trachea by preventing user's chin from coming in contact with user's chest. An unobstructed trachea will allow a sleeping person to inspire and expire air without making a snoring sound.

The foregoing description and drawings merely explain and illustrate the invention and the invention is not limited thereto except insofar as the appended claims are so limited as those skilled in the art having the disclosure before them will be able to make modifications and variations therein without departing from the scope of the invention.
