Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chin support tool for suppressing opening of the oral cavity during sleep.

The following [1] to [3] are examples of chin support tools for suppressing opening of the oral cavity during sleep.
[1] Equipped with a ring-shaped mandibular holding band that spans between the top of the head and the lower jaw, and a maxillary holding band that extends on both left and right sides along the upper jaw of the mouth, so that the lower jaw does not descend and the upper jaw is A belt-like structure that is tightened and fixed so as not to be lifted (see Patent Document 1).
[2] A device in which the upper edge of a supporter wrapped around the neck is brought into contact with the mandible to suppress the lowering of the mandible (see Patent Document 2).
[3] A harness made of resin is placed under the chin on the front side of the neck to suppress the descent of the lower jaw during sleep (see Patent Document 3).

Utility model registration No. 3191180 (see paragraph "0021" and drawings "Fig. 1" and "Fig. 5") Utility model registration No. 3210961 (see paragraphs "0013" and "0014" and "Fig. 1" and "Fig. 2" of the drawings) Utility model registration No. 3106876 (see paragraphs "0024" and "0025" and "Fig. 1" and "Fig. 4" of the drawings)

In the structure shown in Patent Document 1, a belt-shaped belt is provided around the mouth and over the top of the head, and is fixed by strongly tightening, so there is a problem that it is uncomfortable and difficult to sleep. There is In addition, with this structure, the hair is held by the belt and becomes curled, and there is a fear that the hair styling process after waking up will be troublesome.
The structure shown in Patent Document 2 is for stabilizing the neck by winding a band-like supporter around the entire neck. Therefore, even if it is effective for the purpose of protecting the neck, it is difficult to use it for sleeping because it gives a feeling of oppression when sleeping with it wrapped.
In the structure shown in Patent Document 3, a member composed of a resin base material, an adhesive member, an exterior material, etc., molded in a shape close to the front side around the neck is attached to the user in a supine posture. It is used by bringing it into contact with the front side around the neck. In this case, even if there is a certain degree of adhesiveness due to the resin material, it is easy to come off from under the chin or shift due to changes in the sleeping posture of the user, and it cannot be said to be practical.

To provide a chin support with a simple structure, which can easily suppress unconscious opening of the oral cavity and can be worn in a state of less discomfort during sleep.

The chin support of the present invention comprises a chin support that can contact the lower side of the mandibular body of the chin, and a wearing strap that presses and urges the chin support against the chin of the user. The chin support is provided on both the left and right sides of the part corresponding to the lower side of the mandibular body, the mandibular part located away from the chin part at the front end of the mandible toward the angle of the mandible as a contact target. The left and right chin support portions are provided with cushion portions that abut on the lower jaw portion, and the chin support portion is placed in contact with the lower jaw portion at a portion of the chin support portion that faces the front surface of the user's neck. It is characterized in that it has a recessed space forming portion that creates a gap between it and the front surface of the user's neck when it is worn.

According to the present invention, a pair of right and left chin support portions composed of a cushion member capable of abutting against the lower jaw portion of the jaw is provided. The support is in contact. Due to this contact, the chin support suppresses the descent of the jaw, and there is an effect that it is easy to suppress the opening of the oral cavity during sleep.
At this time, even if the sleeping posture of the user changes, such as when the user rolls over, the chin support is pressed and urged against the chin of the user by the wearing strap, so that the lower jaw and the chin support do not contact each other. There is no big change in the contact state, and it is easy to stably suppress the lowering of the jaw.
In addition, since there is a recessed space forming portion that creates a gap between the front surface of the user's neck and the chin support in the worn state at a location facing the front surface of the user's neck, there is a risk of pressing the front side of the neck. It can be used in a small amount.
That is, generally, the neck does not have a perfect circular cross-sectional shape, but has a tapered cross-sectional shape in which the place where the Adam's apple is located protrudes forward. For this reason, if a mere belt-shaped body is wrapped around the neck, there is a tendency for the person to feel suffocation due to pressure on the place where the Adam's apple exists. In contrast, in the present invention, since the recessed space forming portion is formed on the front side of the neck on the side of the chin support, the front side of the neck is less likely to be pressed by the chin support.
As a result, a chin support tool that is easy to wear in a state of less discomfort during sleep can be obtained with a simple structure in which a recessed space forming part is simply provided between the left and right chin support parts. .

In the above configuration, it is preferable that an air passage for opening the recessed space forming portion to the outside in front of the neck portion is formed in the intermediate portion of the position connecting the left and right chin support portions.

By providing this configuration, the recessed space forming portion communicates with the outside in front of the neck through the ventilation path, and hot air is less likely to be trapped in the recessed space forming portion.

In the above configuration, it is preferable that the chin support section is configured to be separable into the left chin support section and the right chin support section.

With this configuration, the chin support can be separated into the left chin support and the right chin support, and can be easily attached and detached by a winding operation.
In addition, when the wrapping operation is performed, the right and left chin support portions can be attached and detached from each other at the front portion of the face instead of at the lateral portion or the rear portion of the face. Therefore, even though it is attached to the underside of the chin, where it is difficult to see visually, it is possible to accurately grasp the attachment/detachment position by keeping the distance between the fingers without relying on visual observation, and perform the attachment/detachment operation in a comfortable posture. Easy to do.

In the above configuration, the chin support is provided with a connection piece at an end opposite to the side provided with the attachment strap, among both ends of the cushion in the left-right direction, The cushion portion is configured by connecting a front cloth positioned on the front surface of the chin support and a rear cloth positioned on the rear surface of the chin support portion, and the connecting piece portion is located on the front side of the boundary portion between the front surface and the rear surface of the cushion portion. is preferably provided at a position biased to the

By providing this configuration, the cushion portion of the chin support portion can be positioned outside the chin support portion by a straight line that connects the attachment band portion located on one end side in the left-right direction and the connecting piece portion located on the other end side. The inner side, that is, the side where the neck portion exists, has a larger volume than the inner side.
Therefore, it is easy for the user to put the cushion part on the laterally outward side of the lower jaw part while the cushion part is put under the lower jaw part. In other words, it becomes easier to maintain a state in which the lower jaw is firmly supported.

In the above configuration, the cushion member includes a first cushion layer portion that can face and abut on the lower jaw portion, and a second cushion layer portion that is located farther from the lower jaw portion than the portion facing the lower jaw portion of the first cushion layer portion. and a cushion layer portion, wherein the second cushion layer portion preferably has an elastic restoring force greater than that of the first cushion layer portion.

With this configuration, the cushion member has a multi-layered structure consisting of the first cushion layer portion and the second cushion layer portion. It is easy to properly maintain the feel at the chin support and the support function at the chin support.

In the above configuration, the first cushion layer portion is a fluid layer configured to be shape-changeable by filling a fluid cushion material that can flow inside the first cushion layer portion, and the second cushion layer portion. It is preferable that the layer portion is a repulsive layer containing an elastic body capable of volume elastic deformation.

With this configuration, the fluid layer, which is configured to be shape-changeable with the fluid cushion material inside, deforms into a shape that follows the shape of the lower jaw, contacts the lower jaw over a wide area, and the contact surface Since the surface pressure is reduced, it is easy to obtain a good feeling of use. At the same time, the appropriate repulsive action of the repulsive layer makes it easy to suppress the movement of the jaw toward the opening side.

In the above configuration, the first cushion layer portion includes an outer storage bag that stores the fluid cushioning material, and the second cushion layer portion includes an elastic body capable of volume elastic deformation inside the outer storage bag. An inner storage bag is provided, and the inner storage bag has an inner communication port formed on one end side of the storage space portion, which can communicate with the inner space of the outer storage bag, and the other end side, which communicates with the outside of the outer storage bag. Advantageously, a possible external communication opening is formed.

With this configuration, the inner storage bag can be used as a guide cylinder for guiding filling of the fluid cushioning material into the first cushion layer portion of the outer storage bag. Therefore, it is not necessary to separately provide a guide tube necessary for guiding the filling of the fluid cushioning material into the outer storage bag and an inner storage bag and guide tube for accommodating the elastically deformable elastic body.
As a result, the overall structure is simplified and the appearance of the cushion portion is improved, compared to the case where the guide tube leading to the first cushion layer portion and the guide tube leading to the second cushion layer portion are separately provided. Easy to keep.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.
Note that the front-rear direction, the left-right direction, and the up-down direction in the description of the embodiments are described as follows unless otherwise specified.
In other words, for convenience of explanation, the case where the chin support 1 of the present invention is attached to the user's body in an upright position is described as a reference, although this is different from the normal sleeping pattern.
According to this standard, the direction in which the front side of the user in an upright posture faces (see arrow F in FIGS. 1 and 2) is "front", and the direction in which the back side faces (see arrow B in FIGS. 1 and 2) is "back". , the direction corresponding to the right side (see arrow R in FIGS. 1 and 2) on the basis of the upright forward posture is "right", and the direction corresponding to the left side (see arrow L in FIGS. 1 and 2) is "left". Similarly, the upper side (see arrow U in FIGS. 3 and 4) in an upright posture is "up", and the lower side (see arrow D in FIGS. 3 and 4) is "down".

〔overall structure〕
As shown in FIGS. 1 to 6, the chin support 1 includes a chin support 2 that abuts the chin, and a wearing band 4 for attaching the chin support 2 to the user's body. I have.
The chin support 2 abuts on the lower side of the chin to provide resistance to the downward movement of the chin, thereby suppressing the movement of the mouth toward the opening side during sleep. A cushion material 30 (see FIG. 6) is provided inside the body 20 (corresponding to an outer housing bag).
The attachment band 4 is for stabilizing the position and posture of the chin support 2 with respect to the user, and is made of an elastic band-like member such as a rubber band that can be stretched.

[Chin support]
As shown in FIGS. 3 and 4, the chin support 2 abuts on the mandibular portion C0 of the mandibular body of the user's jaw, which is positioned away from the mandibular angle C2 relative to the chin portion C1 at the front end position. It is an object and is provided on both the left and right sides.
Each of the left and right chin support portions 2 has a body portion 2A (corresponding to a cushion portion) formed in a circular shape when viewed from the front, as shown in FIG. . A front connecting portion 2B (corresponding to a connection piece portion) located at the end of the neck N near the front side is provided at the left-right end of the main body portion 2A, and the side near the rear of the neck N is provided. A band connecting portion 2C for attaching the wearing band portion 4 is provided at the end of the belt.

FIG. 6 shows the cross-sectional shape of the left body portion 2A of the body portion 2A shown in FIG. 5, taken along the line VI-VI in the thickness direction.
As shown in FIG. 6, the body portion 2A is formed in a circular shape when viewed from the front, but when viewed in cross section, the dimension in the vertical direction, which is the outer diameter d1, is larger than the dimension in the thickness direction d2. It has an oval shape. In other words, the overall shape of the main body 2A is generally close to a sphere, but not a perfect sphere, but a sphere that is slightly compressed in one direction.

As shown in FIGS. 3, 4 and 6, the body portion 2A abuts on the lower jaw portion C0 near its upper portion.
At this time, when the user is lying in a supine position, the head is slightly lifted by the pillow, and the distance between the lower jaw part C0 and the part in the vicinity of the chest facing the lower jaw part C0 is slightly shortened. As a result, the lower portion of the body portion 2A comes into contact with a portion of the body facing the lower jaw portion C0, such as a part of the body near the clavicle, and the body portion 2A supports the lower jaw portion C0 from below.

When the user is lying in a recumbent position, the distance between the lower jaw portion C0 and the portion of the body facing the lower jaw portion C0 is not necessarily shortened, but the main body portion 2A is a wearing belt portion. Since it is attached around the neck at 4, it is avoided to leave the abutment position with respect to the lower jaw portion C0.
Then, in the lying posture, part of the main body 2A is sandwiched between the head and the pillow and fixed in position, or part of the main body 2A is positioned between the head and the futon or either the left or the right. The body portion 2A abutting on the lower jaw portion C0 suppresses the lowering of the lower jaw portion C0.

The left and right main body portions 2A are provided with front connecting portions 2B at the ends near the front side of the neck portion N, and band connecting portions for attaching the wearing band portions 4 to the ends near the rear side of the neck portion N. 2C is provided.
The vertical width h1 of the front connecting portion 2B and the belt connecting portion 2C is set to be smaller than the outer diameter d1 of the main body portion 2A. Therefore, a space h2 corresponding to the vertical height of the air passage 5 is formed between the lower edge of the front connecting portion 2B and the part of the body that faces the front connecting portion 2B. The lateral width w1 of the air passage 5 is determined by the interval between the left and right body portions 2A.

When the chin support part 2 is viewed from above, as shown in FIG. 2, the left and right body parts 2A are attached to the left and right sides of the user's neck N at positions slightly closer to the front side. At this time, the front portions of the left and right body portions 2A are connected by the front connecting portion 2B, and the band connecting portions 2C provided at the rear portions of the left and right body portions 2A are connected via the mounting band portion 4. As shown in FIG.
With the chin support 1 attached, a recessed space forming portion is formed between the front neck portion Nf where the Adam's apple exists on the front side of the neck portion N, the front connecting portion 2B, and the left and right body portions 2A. S is formed. Due to the presence of this recessed space forming portion S, a gap is generated on the front side of the neck portion N, and it is possible to avoid the neck front end portion Nf from being pressed from the front side by the chin support portion 2, so that the chin can be held in a state of less pressure. The support part 2 can be attached.

In order to maintain the state in which the space is formed by the recessed space forming portion S, the left and right body portions 2A are attached as shown in FIGS.
That is, with the upper parts of the left and right main body parts 2A in contact with the lower jaw part C0, the front parts of the main body parts 2A at positions facing the neck N are connected to each other via the left and right front connecting parts 2B. The rear portions of the left and right main body portions 2A are connected via the attachment band portion 4. As shown in FIG. At this time, the length of the front connecting portion 2B in the left-right direction is set and the length of the wearing belt portion 4 in the left-right direction is adjusted so that the front connecting portion 2B does not press the vicinity of the neck front end portion Nf of the neck portion N. A recessed space forming portion S is formed between the front connecting portion 2B and the neck front end portion Nf.
The space formed by the presence of the recessed space forming portion S communicates with the outer space of the chin support 1 via the air passage 5 existing below the front connecting portion 2B. In other words, the ventilation path 5 serves as an air supply/exhaust path capable of discharging hot air trapped in the gap and introducing outside air into the gap.

The front connecting portions 2B connecting the front portions of the left and right body portions 2A are provided with male and female hook-and-loop fasteners 24 on the rear facing surface of one front connecting portion 2B and the front facing surface of the other front connecting portion 2B. be. Therefore, by holding the left and right front connecting parts 2B with the left and right hands respectively to engage and disengage the male and female hook-and-loop fasteners 24, the chin support 1 can be easily attached to and released from the neck N.
In other words, it is difficult to directly see the lower side of the mandibular portion C0 by oneself. I will have to do it by hand. For this reason, if the structure of the connecting means for engaging and disengaging the front connecting portions 2B is complicated, it is likely to be difficult to visually check in a mirror in which the left and right sides are reversed or to operate by fumbling. Since the hook-and-loop fastener 24 is used as a connecting means for engaging and disengaging the front connecting portions 2B, it is easy to operate simply by moving the surfaces of the hook-and-loop fastener 24 from each other. Moreover, since the engagement/disengagement operation is performed on the front side of the neck portion N, there is little left-right sensible deviation, and the operation can be performed relatively easily in a supine posture without the need for visual observation.

The attachment strap 4 is provided at the end on the side closer to the rear side of the neck N at the end on the side opposite to the side on which the front connecting portion 2B is provided among the left and right ends of the body portion 2A. It is connected to the band connecting portion 2C.
One end side of the mounting band 4 is sewn to the band connecting portion 2C of one of the band connecting portions 2C provided on the left and right body portions 2A.
The other end side of the wearing belt portion 4 is connected by a fastener 25 such as a synthetic resin or metal adjuster or joint attached to the belt connecting portion 2C of the other main body portion 2A. By appropriately changing the connecting length of the attachment strap 4 to the fixture 25, the attachment state of the chin support 1 to the neck N can be adjusted.

[About the cushion part]
In the left and right body portions 2A, a cushion material 30 is sealed inside bag-shaped cover bodies 20 (corresponding to outer storage bags).
The bag-shaped cover body 20 is formed by stitching together a fabric peripheral edge portion 21a of the front fabric 21 located on the front side and a fabric peripheral edge portion 22a of the rear fabric 22 located on the rear side, so that the upper and lower sides are circular. It is formed in an arcuate bag shape.
At least one of the front fabric 21 and the rear fabric 22 is preferably made of a biaxially stretched fabric. In this embodiment, the front cloth 21 is composed of a non-stretchable or less stretchable cloth material, and the rear cloth 22 is composed of a stretchable stretch cloth.

In the front cloth 21 and the rear cloth 22, the front connecting portion 2B is integrally formed with a series of cloths at the edge portions closer to the front side, and the band connecting portion 2C is integrally formed with a series of cloths at the edge portions closer to the rear side. formed.
As shown in FIGS. 1 and 5, a reinforcing belt 23 is provided across the front surface of the front cloth 21 from the front connecting portion 2B to the belt connecting portion 2C. The reinforcing band 23 is provided with a hook-and-loop fastener 24 for engaging and disengaging at the end on the front connecting portion 2B side.

A cushion material 30 is provided inside the cover body 20 .
The cushion material 30 includes a first cushion layer 31 that can face and contact the lower jaw portion C0, and a second cushion layer that is located farther from the lower jaw portion C0 than the portion of the first cushion layer 31 facing the lower jaw portion C0. 32 , and is composed of a combination of the first cushion layer 31 and the second cushion layer 32 .

The first cushion layer 31 in the cover body 20 is a layer filled with a fluid cushion material 31a that allows relatively free movement within the first cushion layer 31 . As the fluid cushioning material 31a, for example, fine granular cushion beads made of a polyurethane material are used.
The fluid cushioning material 31a is provided inside the closed space inside the cover body 20 in such a manner that the fine particles can flow. In other words, each cushion bead has a certain degree of elastic repulsive force, but can flow inside the cover body 20 so that the surface pressure is evened according to the pressure acting from the outside of the cover body 20. is enclosed in In this manner, the cushion beads are allowed to move only within the internal space of the cover body 20, so that the surface shape of the cover body 20 can be varied in various ways. As a result, the first cushion layer 31 does not have a large repulsive force, but functions as a cushion.

The second cushion layer 32 is enclosed inside the inner bag 26 (corresponding to an inner housing bag) positioned inside the cover body 20 . That is, the second cushion layer 32 is positioned inside the cover body 20 while being surrounded by the first cushion layer 31 such as cushion beads enclosed in the cover body 20 . In this state, the second cushion layer 32 is located farther from the lower jaw portion C0 than the portion of the first cushion layer 31 facing the lower jaw portion C0.
An elastic body 32 a capable of volume elastic deformation is enclosed inside the inner bag 26 so as to constitute the second cushion layer 32 . As the elastic body 32a, cotton made of a polyurethane material, sponge rubber, or the like is used. Therefore, the second cushion layer 32 is configured to play a role as a repulsion layer having an elastic restoring force greater than that of the first cushion layer 31 enclosing the cushion beads.

The inner bag 26 also serves as a filling guide tube for filling cushion beads into the cover body 20 .
That is, as shown by the solid line in FIG. 8, the inner bag 26 is connected to the inside of the cover body 20 via the cylindrical connecting portion 27 (corresponding to the inner communication port) while protruding outside the cover body 20. The inner bag 26 is formed with an opening 26a (corresponding to an outer communication port). In this state, the cushion beads can be filled into the cover body 20 from the opening 26 a of the inner bag 26 through the inner bag 26 and the cylindrical connecting portion 27 .
Then, the inner bag 26 can change its position to enter the inside of the cover body 20, as indicated by the phantom lines in FIG. In this state, the elastic body 32a can be inserted into the inner bag 26 from the open end 27a of the cylindrical connecting portion 27. As shown in FIG.

The order is as follows: as shown by the solid line in FIG. A first cushion layer 31 is provided outside the inner bag 26 within the cover body 20 by filling the cushion beads in the inner bag 20 and sewing or bonding the opening 26a of the inner bag 26 to close it.
After that, the inner bag 26 is turned upside down and pushed into the cover body 20 so as to be in the state shown by the phantom lines in FIG. A second cushion layer 32 is provided if the body 32a is filled. As a result, the cushion material 30 formed by combining the first cushion layer 31 and the second cushion layer 32 is sealed inside the main body 2A.
The elastic body 32a constituting the second cushion layer 32 filled in the inner bag 26 is less likely to leak out from the cylindrical connecting portion 27. As shown in FIG. Therefore, it is not necessary to close the open end 27a of the cylindrical connecting portion 27 to the outside. It may be closed by an appropriate means such as adhesion.

[About the front connecting part]
The front connecting portion 2B is configured as follows.
As shown by the solid line in FIG. 7, the front connecting portion 2B is provided at a position shifted toward the front surface Ff from a boundary portion 28 between the front surface Ff and the rear surface Rf in the main body portion 2A in plan view.
A boundary portion 28 between the front surface Ff and the rear surface Rf is generally at a position substantially coinciding with the cloth material peripheral edge portions 21a and 22a where the front cloth 21 and the rear cloth 22 are joined. When the portion 2B is positioned, it will be in the position indicated by the phantom lines in the figure.

As described above, when the front connecting portion 2B is attached to the main body portion 2A while being biased toward the front face Ff side from the boundary portion 28, it is possible to slip under the lower jaw portion C0 within the total volume of the main body portion 2A. It is easy to ensure a large proportion of the volume of the part.
That is, when the body portion 2A is attached to the circumference of the neck portion N, a force is applied to pull the front connecting portion 2B and the band connecting portion 2C in opposite directions. At this time, looking at the volume of the body portion 2A with the line segment L1 connecting the front connecting portion 2B and the belt connecting portion 2C as a boundary, the volume on the side where the neck portion N exists from the line segment L1 is larger than the line segment L1. is larger than the volume on the side away from the neck N.
Therefore, the volume of the portion of the lower jaw portion C0 that can be slipped under, that is, the volume on the side of the line segment L1 on which the neck portion N exists, is larger than the volume on the opposite side of the line segment L1. This makes it easy to secure the volume of the body portion 2A necessary for supporting the lower jaw portion C0 without increasing the volume of the entire body portion 2A more than necessary.

[Another Embodiment 1]
