Description

It relates to a pillow that can support the head, cervical spine, and shoulders by changing the support height of the cervical spine by inverting a part of the pillow and connecting it in opposite positions.

Pillows have a great influence on the quality of sleep, as it is said that you cannot sleep if you change the pillow. By using a pillow that suits your physical condition, you can rest your overworked cervical spine and ensure a good night's sleep. In modern society, there is a tendency to use electric appliances such as smartphones for a long time, and the burden on the cervical spine is increasing, so the importance of pillows is increasing.

Conventionally, many pillows with a bale-shaped cross section and a double-humped shape have been used, but since these pillows support only the cervical spine and the head, there is a gap in the shoulder part and the cervical spine. Was not enough to support. As a result, the cervical spine and shoulders were strained, and it was not possible to sleep soundly.

As a remedy, pillows that can support not only the cervical spine and head but also the shoulders have been proposed. For example, in Patent Document 1, the space is made more efficient and the handling is simplified by folding it into a small size in an unused state, and the user's cervical spine and various parts of the body are maintained in a natural state in the used state. Pillows have been proposed that can keep warm around the shoulders as well as possible.

Patent Document 2 proposes a pillow having a simple shape that is comfortable and comfortable for the user by changing the hardness of the supporting portion to ease the burden on the user's neck at bedtime.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the pillow 1 has a main body 10 and an inclination adjusting body 20, and these are held in a connected state by a connecting device 30. The pillow 1 is placed on the mounting floor 100, and the contact surface 23 and the first contact surface 23 and the first are in a state where the mounting surface 14 of the main body 10 and the first ground contact surface 21 of the inclination adjusting body 20 are in contact with the mounting floor 100. The contact surface 11a comes into contact with each other. Further, the contact surface 23 and the second contact surface 12a come into contact with each other in a state where the tilt adjusting body 20 is inverted and the mounting surface 14 and the second ground contact surface 22 are brought into contact with the mounting floor 100.

The main body 10 is a member that mainly supports the cervical spine and the head, and as shown in FIG. 2, the cross-sectional shape is defined by the first support surface 11, the second support surface 12, the recessed support surface 13, and the mounting surface 14. Will be done.

The first support surface 11 is a portion mainly for supporting the cervical spine, and has a first contact surface 11a that is entirely formed of a curved surface and can contact the contact surface 23 of the inclination adjusting body 20. There is. Similarly, the second support surface 12 is also a portion mainly for supporting the cervical spine, and has a second contact surface 12a that is entirely formed of a curved surface and can contact the contact surface 23 of the inclination adjusting body 20. doing.

The first support surface 11 and the second support surface 12 are curved surfaces that are convex upward. The curved surface along the cervical spine can support the cervical spine evenly. Regardless of this, if the curvature is smaller than the curved surface along the cervical spine, it is possible to give an appropriate stimulation to the cervical spine. Further, the height H1 of the first support surface 11 is set higher than the height H2 of the second support surface 12. This allows the cervical spine to be supported at different heights.

The first contact surface 11a and the second contact surface 12a have a so-called point-symmetrical shape in which one of them is rotated to overlap the other at the same position. Further, each end portion is connected to the end portion of the mounting surface 14. The mounting surface 14 is a flat portion, and the pillow 1 is stably placed in contact with the mounting floor 100.

The recessed support surface 13 is a portion mainly for supporting the head, and is provided in connection between the first support surface 11 and the second support surface 12. The concave support surface 13 is a curved surface that is concave downward. The head can be supported evenly by forming a curved surface that follows the shape of the head.

The tilt adjusting body 20 is a member mainly for supporting the vertebrae and shoulders from the lower joint of the cervical spine, and as shown in FIG. 3, the cross-sectional shape is the first ground contact surface 21, the second ground contact surface 22, and the contact. It is a substantially triangular cross-sectional shape defined by the surface 23.

The first ground contact surface 21 and the second ground contact surface 22 are rectangular flat surfaces, and when the inclination adjusting body 20 is placed on the mounting floor 100, it comes into contact with the mounting floor 100. Further, each of them is connected by a connecting contact 25. The length L1 of the first contact patch 21 in cross-sectional view is set shorter than the length L2 of the second contact patch.

In cross-sectional view, the angle formed by the first contact patch 21 and the second contact patch 22 is preferably about 20 degrees. It is said that the optimum angle when sleeping is about 15 degrees, but this is the result of considering the sinking during use.

The contact surface 23 is a curved surface that is in contact with the ends of the first ground contact surface 21 and the second ground contact surface 22 and is concave toward the joint contact 25. The shape is the same as that of the first contact surface 11a and the second contact surface 12a.

The main body 10 and the tilt adjusting body 20 are connected to each other via connecting devices 30 provided at both side ends (front side and back side in FIG. 1). The connecting device 30 has a structure in which strings 31a and 31b having expansion and contraction performance are connected via a plug-in type connecting tool 32. The string 31a is fixed to the main body, and the string 31b is fixed to the inclination adjusting body 20. The connector 32 has a structure in which it is connected and integrated by inserting it, and separated by pulling it out. As a result, the main body 10 and the tilt adjusting body 20 are separably connected.

Examples of the main body 10 and the tilt adjusting body 20 are urethane foam covered with a cloth. Cost reduction can be achieved by making each inside a single structure. The hardness of the main body 10 and the inclination adjusting body 20 may be the same or different. By appropriately and appropriately setting the hardness of the main body 10 and the inclination adjusting body 20, the pillow can be made suitable for people of various body shapes such as fat people and thin people.

A standard usage mode of the pillow 1 will be described with reference to FIG.

The main body 10 and the tilt adjusting body 20 are placed on the mounting floor 100. With the mounting surface 14 and the first ground contact surface in contact with the mounting floor 100, the connector 32 is inserted. As a result, the compressive force is urged on the entire surface of the first contact surface 11a and the entire surface of the contact surface 23, and the main body 10 and the inclination adjusting body 20 are integrated.

In this state, the first support surface 11 mainly supports the cervical spine, the second contact patch 22 of the tilt adjusting body 20 mainly supports the vertebrae and shoulders, and the concave support surface 13 mainly supports the head. The support height of the cervical spine at this time is the height H1 of the first support surface.

As shown in FIGS. 5A and 5B, conventionally, a bale-shaped pillow 2 and a double-humped pillow 3 have been widely used. Since these pillows do not support the shoulders, they place a heavy burden on the cervical spine and are likely to affect sleep quality such as stiff shoulders, insomnia, and snoring. Since the pillow 1 shown in the present embodiment can integrally support the head, the cervical spine, and the shoulders, the quality of sleep can be improved.

The second ground contact surface 22 and the first support surface 11 are set to be connected with the same gradient. As a result, a continuous and smooth supporting surface can be obtained, and the supporting pressure can be made uniform from the cervical spine to the shoulder.

Since the first contact surface 11a and the contact surface 23 having the same shape as the first contact surface are curved surfaces, the range of compressive force in which the connection area is greatly urged as compared with the case where each is a flat surface. Is widened, and the integration of the main body 10 and the tilt adjusting body 20 is further promoted. As a result, it is possible to avoid the occurrence of a gap between the main body 10 and the tilt adjusting body 20 at bedtime.

By reversing the tilt adjusting body 20, the entire surface of the second contact surface 12a comes into contact with the entire surface of the contact surface 23 in a state where the compressive force is urged, and the main body 10 and the tilt adjusting body 20 are integrated. To do. The support height of the cervical spine at this time is the height H2 of the second support surface. Since this state is almost the same as the above-mentioned contents, the description thereof will be omitted.

As described above, the cervical spine support height when the first contact surface 11a and the contact surface 23 are in contact with each other is the height H1 of the first support surface, and the inclination adjusting body 20 is inverted to form the second contact surface. The height of the cervical spine support when the contact surface 23 is brought into contact with the 12a is the height H2 of the second support surface, which is lower than the height H1 of the first support surface.

Since the second contact patch 22 is longer in cross-sectional view than the first contact patch 21, the second support is provided when the support height of the cervical spine is increased, that is, when the cervical spine is supported by the first support surface. The range of supporting the shoulder can be set wider than when the cervical spine is supported by the surface.

Suitable pillow heights vary depending on the body shape, such as large people, small people, fat people, thin people, people with deep curves of the cervical spine, and people with shallow cervical spine. The pillow shown in this embodiment is a pillow that can support from the head to the cervical spine to the shoulder, can support the cervical spine at different support heights, and can change the support range of the shoulders, and is preferably used by many people. It will be a pillow that you can do.

For example, it is common for large people to increase the support height of the cervical spine. In this case, the shoulder is supported by the second contact patch 22. Since the length of the second contact patch 22 is longer than the length of the first contact patch 21 in cross-sectional view, the support range can be widened according to the size of the shoulder of a large person. In addition, for a small person, the support length of the shoulder can be shortened by lowering the support height of the cervical spine, and in either case, it can be set appropriately.

Other usage modes will be described with reference to FIGS. 4A, 4B, and 4C.

As shown in FIG. 4A, the main body 10 may be laminated on the tilt adjusting body 20 with the mounting surface 14 of the main body 10 facing up. The height of the pillow can be increased so that the head and cervical spine can be supported at a suitable height when lying down and relaxing.

As shown in FIG. 4B, the main body 10 may be laminated on the inclination adjusting body 20 in a state where the first ground contact surface 21 and the mounting surface 14 are in contact with each other. In this case, the height of the pillow can be further increased.

As shown in FIG. 4C, by placing the arm on the concave support surface 13 and the neck to chest on the first support surface 11 and the second ground contact surface 22, the patient can lie down in a comfortable prone position. The usage modes shown in FIGS. 4A to 4C are merely examples, and it goes without saying that various other usage modes can be supported.

The pillow according to the present invention has great industrial applicability because it can improve the comfort at bedtime for people of various body shapes and can be used in various modes.
