Some people prefer a supine position when sleeping, while others prefer a lying position (also called a side-lying position). Further, for example, some people who have accumulated fatigue all over their body due to long working hours take a prone position and fall asleep on the bed. As described above, people sleep in various sleeping positions, and there is a demand for pillows that can accommodate various sleeping positions.

The present invention provides a pillow that can accommodate various sleeping positions.

A pillow according to the present invention comprises a first pillow member and a second pillow member used in combination with the first pillow member. The first pillow member comprises a head support part on which at least a person's head rests, and a pair of head support parts which are formed integrally with the head support part and protrude obliquely downward from the head support part and are line-symmetrical with respect to the center line of the head support part. and a recess bounded by the lower end of the head support and the inner edges of the two protrusions. The recess has an opening width that fits the shoulders of a person lying down. The second pillow member has a base on which the head support of the first pillow member can rest.

According to the pillow according to the present invention, various sleep positions can be accommodated. In the supine position, the pair of protruding portions of the first pillow member are positioned laterally around the person's head and neck, so that the person's head is firmly supported, gently wrapped, and placed stably. placed. Since the head support is placed on the base of the second pillow member, even if the weight of the head is applied to the area of the head support, only the area of the head support does not unnaturally fall downward. do not have. This maintains a natural supine posture.

In the lying position, the arm can be passed through the space created below the overhang. As a result, the protruding portion is superimposed on the upper part of the arm, and even if the sleeping posture changes during the lying posture and the arm becomes a pillow, the weight of the head applied to the arm is moderately absorbed or dispersed. be able to. Further, in the lying posture, in addition to the normal lying posture, the sleeping posture can be taken with the arms extended toward the head side from the horizontal position of the shoulders. The movement of extending the arms above the head is also a stretching movement that loosens the muscles around the shoulders. It is also possible to smoothly change the sleeping position between the lying posture and the lying posture.

In one embodiment of the first pillow member, the longitudinal length of the head support is at least three times the depth of the recess, and the length of a straight line connecting the center of the head support and the tip of each overhang is: Longer than the vertical length of the head support. This allows the first pillow member to be dimensioned more suitable for resting a person's head.

Another embodiment of the first pillow member is curved at the top of the head support and at the tip of each ledge, wherein the curvature at the top of the head support is the curvature at the tip of each ledge. Larger radius of curvature. As a result, the first pillow member has a rounded shape, and the feeling of fit and the sense of security are improved.

In preferred embodiments of the first and second pillow members, the first and second pillow members are substantially identical in planar shape, and the second pillow member is the head support portion of the first pillow member. a pair of protrusions formed integrally with the base and projecting obliquely upward with respect to the base and forming line symmetry with respect to the center line of the base; an upper end of the base and two extensions; and a recess surrounded by the inner edge of the protrusion.

As a result, the pillow according to the present invention can accommodate various sleeping positions. That is, in the prone position, the right arm and the left arm can be passed through the left and right spaces, respectively, and the protruding portion of the second pillow member can be embraced, so that the natural prone position can be maintained. Since the head can be fitted in the depression of the recess of the second pillow member, a feeling of fit and security can be obtained, and breathing is easy. Furthermore, by placing the arms on the protruding portion of the second pillow member, the user can assume a prone posture with both arms extended toward the head at a gentle slope, so that the muscles around the shoulders can be relaxed. It can also be used as a relaxing stretching action.

In another preferred embodiment of each of the first and second pillow members, each of the first and second pillow members is a cloth bag filled with a filler having cushioning properties, and the first and second pillow members are filled with a cushioning material. The filler with which the cloth bag is filled is a softer material than the filler with which the cloth bag of the second pillow member is filled. Thereby, the cushioning property of each pillow member becomes more suitable, and the comfort during sleep is improved.

A preferred embodiment of the pillow is a pillow cover that can accommodate the first and second pillow members while the head support portion of the first pillow member is placed on the base portion of the second pillow member. further provide. Thereby, the positional relationship of the first pillow member and the second pillow member, that is, the degree of overlap is appropriately maintained.

FIG. 5 is a plan view schematically showing a first mode of use of the pillow.

The first mode of use is a mode corresponding to a supine posture, and the pillow 1 is used in the first stacking manner shown in FIG. In the supine posture, a person's head 90 is placed on the head support portion 11 of the first pillow member 10 .

In the first mode of use, the head support portion 11 and the pair of overhanging portions 12, 13 of the first pillow member 10 form a substantially L-shape, and the pair of overhanging portions 12, 13 are positioned to support a person's head. It is located laterally around the neck from the portion 90 . As a result, the head 90 is firmly supported, gently wrapped, and placed stably. Since the head support portion 11 is placed on the base portion 21 of the second pillow member 20, even if the weight of the head portion 90 is applied to the area of the head support portion 11, the pair of overhanging portions 12 and 13 will not be affected. As a result, only the area of the head support portion 11 does not unnaturally drop downward. This maintains a natural supine posture.

FIG. 6 is a plan view schematically showing a second usage mode of the pillow, showing a state in which the pillow is lying down on the right side as viewed from a person. A right arm 91 in a normal recumbent posture is indicated by a chain double-dashed line.

The second mode of use is a mode corresponding to the lying posture, and the pillow 1 is used in the first stacking manner shown in FIG. 3, as in the first mode of use. Further, in the same manner as in the first mode of use, the person's head 90 is placed on the head support portion 11 of the first pillow member 10 even in the lying posture.

In the second mode of use, in addition to the normal lying posture, the lying posture can also be taken with the right arm 91 passing through the space 15 created below the projecting portion 12 . As a result, the protruding portion 12 overlaps the upper part of the arm 91, and even if the sleeping posture changes during the recumbent posture and the arm becomes a pillow, the weight of the head 90 applied to the arm 91 is moderately reduced. Can be absorbed or dispersed. Furthermore, in a lying posture using a conventional rectangular or L-shaped pillow, it was not easy to raise the right arm 91 toward the head 90 from the horizontal position of the shoulder. 1, the right arm 91 can be smoothly raised toward the head 90 from the horizontal position of the shoulder. As a result, in the lying posture, the sleeping posture can be taken with the right arm 91 extended toward the head 90 from the horizontal position of the shoulder. The action of extending the arms 91 and 92 above the head 90 also serves as a stretching action for loosening the muscles around the shoulders.

In addition, in the example shown in FIG. 6, the state of lying down on the right side is illustrated, but the same applies to the case of lying down on the left side. That is, in the second mode of use, in addition to the normal lying posture, the lying posture can be taken with the left arm 92 passing through the space 15 formed below the projecting portion 13 .

Moreover, between the second mode of use and the first mode of use, the method of stacking the pillow 1 and the position on which the head 90 is placed are common. Thereby, the person can smoothly change the sleeping position between the second usage mode and the first usage mode.

FIG. 7 is a plan view schematically showing a third usage mode of the pillow.

The third mode of use is a mode corresponding to the prone posture, and the pillow 1 is used in the second stacking manner shown in FIG. In the prone posture, the area around the chin of the head 90 from the chest of the person is placed on the base portion 21 of the second pillow member 20 .

It is located laterally around the neck from 90 . Further, since the base portion 21 is placed on the head support portion 11 of the first pillow member 10, a space 25 is created below the projecting portions 22 and 23. As shown in FIG. As a result, the right arm 91 and the left arm 92 can be passed through the left and right spaces 25, respectively, and the protruding portions 22 and 23 can be embraced, thereby maintaining a natural lying prone posture. Since the head 90 can be fitted into the depression of the recess 24, a feeling of fit and security can be obtained, and breathing is easy.

FIG. 8 is a plan view schematically showing a fourth usage mode of the pillow.

The fourth mode of use is also a mode corresponding to the prone posture, and the pillow 1 is used in the second way of stacking shown in FIG. 4 as in the third mode of use. As in the third mode of use, the area around the chin of the person's chest to the head 90 is placed on the base portion 21 of the second pillow member 20 .

In the fourth mode of use, the user can take a prone posture with both arms 91 and 92 extended toward the head 90 side. The outstretched left and right arms 91 and 92 are supported by the left and right projecting portions 22 and 23, respectively. At this time, since the base portion 21 is placed on the head support portion 11 of the first pillow member 10, the overhanging portions 22 and 23 integrally formed with the base portion 21 are gently inclined, and both arms 91 , 92 also become gentle. This maintains a natural lying-down position. Since the head 90 can be fitted in the depression of the recess 24, a feeling of fit and security can be obtained, and breathing is easy. The action of extending the arms 91 and 92 above the head 90 is also a stretching action for loosening the muscles around the shoulders.
