Abstract

PURPOSE:To prevent heat generated by the head of the human body from staying in a pillow by forming air flow-in/flow-out ports connected to a void portion and the outside of the side portions of a pillow body and providing one or a plurality of coil springs inside the void. CONSTITUTION:A void portion 1 is formed inside a pillow body A and air flow-in/flow-out ports 2 connected to the void portion 1 and the outside of the side portions of a pillow body A are formed, and one or a plurality of coil springs 8 are provided in the void portion 1 in such a way that the longitudinal direction of the coil springs 8 is nearly conformed to the horizontal direction of the pillow body A, thus forming a pillow having a heat radiating property. Due to the existence of the void portion 1 and the air flow-in/flow-out ports 2, air flows into and out of the pillow body A, thereby promptly cooling the same to prevent the temperature rise thereof. When the head of the human body is placed on the pillow body A, compressing the same with its weight, even though the void portion 1 is slightly compressed, it can be prevented that the void portion 1 is crushed resulting in the interrupted flow-in/flow-out of air because of the coil spring 8.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 16.

A is the pillow body, which is shaped like a flat rectangular parallelepiped. The pillow body A is made of an elastic and flexible material such as sponge, and there is a void l inside the pillow body A.
is formed. An air inlet/outlet 2 communicating between the cavity 1 and the outside of the pillow body A is formed on the side of the pillow body A. The cough side part consists of a side part on the end side in the longitudinal direction (horizontal direction in FIG. 2) and a side part on the end side in the width direction (vertical direction in FIG. 2). In the embodiment, the structure of the pillow body A is formed from a plurality of elastic and flexible pieces such as sponges, and as shown in FIGS. 1 and 2, the upper surface of the pillow body A is The substantially flat upper member a and the lower member forming the lower surface are formed of an intermediate member C which mainly forms the width direction side portion and the longitudinal direction side portion at an intermediate position above and below. First, the intermediate member C is placed and fixed on the lower member, and the upper member a is fixed on the intermediate member C. Here, in order to form the cavity 1, the intermediate members c, c facing each other on the inner side of the upper surface of the lower member are provided with an appropriate interval (sixth
(See Figures 9 to 9).

Further, in order to form the air inlet/outlet 2, the intermediate members c and c are arranged at an appropriate distance from each other at the outer end of the upper surface of the lower member (see Figs. 6 to 9). Alternatively, a hole may be formed directly in the intermediate member C and used as the air inlet/outlet 2.

There are various examples of the shape of the cavity 1, and as shown in FIGS. 6 to 9, there is a rectangular parallelepiped shape similar to the pillow body A, and a cross shape when the pillow body A is viewed from above. There are some that are formed into an X-shape, and others that are formed in an X-shape.

According to the embodiment of the shape of the cavity 1, the intermediate member C is
It is formed in the shape of a rectangular parallelepiped, a cube, or a triangular prism.

In addition, the pillow body A is not composed of small pieces such as the upper member a, the lower member and the intermediate member C as described above.
It is actually made of a single piece of sponge material in the shape of a rectangular parallelepiped.
The inside is often hollowed out to form a void 1.
The air inlet/outlet 2 is formed when hollowing out the gap 1, but an auxiliary piece 3 is used to prevent the coil spring 8 and the pipe-shaped elastic body described later from coming out of the gap 1. Therefore, the air inlet/outlet 2 may be set to an appropriate width (see FIGS. 2, 3, etc.).

In this way, the pillow body A has the void 1 formed inside,
As long as the air inlet 2 is formed at the corner between the widthwise side and the longitudinal side, or the widthwise side and the longitudinal side, the invention is not limited to the above embodiments. .

Next, a large number of chevron-shaped small protrusions 4 may be formed on the upper surface of the pillow main body A (see FIG. 1). In addition, small holes 5, 5 communicating between the cavity 1 inside the pillow body A and the upper surface of the pillow body A are provided.
．． ... may be drilled in large numbers. ! f Many small holes 5,5. A part of the... may extend to the vicinity of the two air inlets.

Such small protrusions 4 and small holes 5 are formed in the upper member a when the pillow main body A consists of a plurality of small pieces.

Next, grooves 6 that are approximately parallel to the longitudinal direction (direction perpendicular to the plane of paper in FIG. 3) and have a flattened arc shape in cross section may be formed on substantially the entire upper surface of the pillow body A (see FIG. 1, (See Figures 3, 10, and 11).

The groove 6 is something that the human head comes into contact with, and the groove 6
The arc-shaped part is extremely gentle and can stably support the back of the head of the human body.

Further, a substantially arcuate constriction 7 may be formed in at least one direction substantially orthogonal to the longitudinal direction of the groove 6 of the pillow body A. That is, at approximately the center of the groove 6 of the pillow body A in the longitudinal direction, an arcuate constriction 7 may be formed in either or both of the directions substantially perpendicular to the longitudinal direction. (See Figure 10). The neck portion of the human body comes into contact with the constricted portion 7, and together with the groove 6, supports the human head, so that no strain is placed on the neck in particular.

The grooves 6 and constrictions 7 formed on the upper surface of the pillow body A as described above are formed on the upper member a when the pillow body A is composed of a plurality of small pieces. However, depending on the case, the upper part of the intermediate member C may be appropriately formed into an inclined shape or an arc shape to form the groove 6 and the constricted part 7 together with the upper member a.

A coil spring 8 is installed inside the gap l. The coil spring 8 is installed inside the pillow body A so that its expansion and contraction direction substantially coincides with the planar direction of the pillow body A, and there are various embodiments in which the coil spring 8 is installed inside the pillow body A.

First, as shown in FIG. 2, FIG. 6, and FIG.
When the space 1 has a substantially rectangular parallelepiped shape, one or more coil springs 8 (three in the figure) are installed in parallel along the longitudinal direction of the space 1.

Further, as shown in FIGS. 7 and 8, when the cavity 1 is cross-shaped, a portion parallel to the longitudinal direction (horizontal direction in FIG. 8) of the pillow body A when viewed from the plane of the pillow body A. A long coil spring 8 is provided in the width direction (vertical direction in FIG. 8) of the pillow body A, and short coil springs 8, 8 are arranged on both sides of the long coil spring 8 in parallel to the width direction (vertical direction in FIG. 8). are arranged respectively.

Further, as shown in FIG. 9, when the cavity 1 is formed in an X-shape, the long coil spring 8 is placed on one diagonal line when viewed from the plane of the pillow body A, and the long coil spring 8 is placed on the other diagonal line. In this case, short coil springs 8.8 are arranged on both sides of a long coil spring 8.

When the coil spring 8 is installed in such a way that the direction of expansion and contraction of the coil spring 8 is parallel to the plane direction of the pillow body, it is preferable that the diameter of the coil spring 8 is slightly smaller than the height h of the gap l. When the human head is placed on the pillow body A, first, only the pillow body A is compressed by the weight of the human head, and then the cavity 1 is also compressed appropriately as shown in FIG. , the upper part of the gap l comes into contact with the coil spring 8, and the coil spring 8 has a diameter R+ approximately equal to its height h+, as shown by the chain line in FIG.
It has a mechanism to contract in an inclined manner, and by the time the coil spring 8 starts to contract, only the members such as the sponge of the pillow body A are contracted first, so that flexibility during use can be maintained.

A sheet 9 of gauze, cloth, or the like may be wrapped around the coil spring 8, as shown in FIGS. 4 and 5. The sheet 9 preferably has 5 air permeability. The reason why the sheet 9 is wound around the coil spring 8 in this way is that a plurality of coil springs 8 are wrapped in the cavity 1.
．． This is to prevent the coil springs 8 and 8 or the coil spring 8 and the pillow body A from becoming entangled when the coil springs 8 and 8 are arranged in parallel.

Next, as shown in FIG. 14, the coil spring 8 may be provided vertically within the gap l, with the expansion and contraction direction of the coil spring 8 perpendicular to the plane direction of the pillow body A. At this time, the lower end of the coil spring 8 can be fixed to a flexible flat plate made of rubber, synthetic resin, etc. that matches the planar shape of the cavity 1, and the entire flat plate can be housed in the cavity 1.

Further, as shown in FIG. 11, a tubular core material 10 may be installed inside the cavity 1 instead of the coil spring 8. The tubular core material 10 is made of rubber.

It is made of an elastic material such as synthetic resin or metal, and is formed into a hollow cylindrical shape so that the diameter is approximately equal to the diameter of the coil spring 8. The tubular core material 10 is
It is preferable to use a material that is as elastic and resilient as possible. Further, as shown in FIG. 13, the tubular core material 1
A large number of small through holes 10a may be bored in the side surface of the 0 to improve ventilation. The tubular core member 10 is also arranged in various states in the cavity l, similar to the arrangement state of the coil spring 8.

11 in the figure is a pillow cover.

〔Effect of the invention〕

First, in the invention of claim 1, a cavity 1 is formed inside the pillow body A, an air inlet/outlet 2 communicating with the cavity 1 and the outside of the side of the pillow body A is formed, and a coil spring 8 is formed. so that the longitudinal direction of the pillow body A and the horizontal direction of the pillow body A approximately match,
- By making the pillow have heat dissipation properties with a plurality of coil springs 8 provided in the cavity 1, first of all, the heat generated from the human head does not get trapped in the pillow body A during sleep, making it comfortable. Second, the pillow body A has appropriate flexibility and has excellent restorability.

To explain these effects in detail, first, a cavity 1 is formed inside the pillow body A, and an air inlet/outlet 2 is formed that communicates between the cavity l and the outside of the side of the pillow body A. Air always flows in and out of the main body A. Therefore, even if the heat generated from the body temperature of the human head is transmitted to the pillow body A, due to the existence of the gap 1 and the air inlet/outlet 2, air flows in and out, and the pillow body A is immediately cooled. It is possible to prevent the temperature rise of A, allowing a comfortable sleep, and the effect is especially great when used in the summer.

Also, in the cavity 1, one or more coil springs 8 are arranged parallel to the plane direction of the pillow body A, so that the human head is placed on the pillow body A, and its weight is applied to the pillow body A. Even when compressed, the gap 1 is slightly compressed, but the coil spring 8 can prevent the gap 1 from collapsing and preventing air from flowing in and out. In addition, the coil spring 8 is not blocked from entering or exiting air at any point in its longitudinal direction (expansion/contraction direction), and the inside of the cavity 1 can be cooled uniformly at all times.

Moreover, since the coil spring 8 can be deformed even in a direction substantially perpendicular to the direction of expansion and contraction (see FIG. 3), the pillow body A
Comfortable elasticity can be obtained by the synergistic effect of the expansion and contraction of the coil spring 8 and the expansion and contraction of the coil spring 8.

Next, in the invention according to claim 2, a cavity l is formed inside the pillow body A, an air inlet/outlet 2 communicating between the cavity 1 and the outside of the side of the pillow body A is formed, and a coil spring is formed. so that the longitudinal direction of 8 and the horizontal direction of the pillow body A substantially match,
One or more coil springs 8, 8. ... is provided in the cavity 1, and a sheet 9 is wound around each coil spring 8 to form a pillow with heat dissipation properties.
Inside the coil springs 8, 8. ... etc. can be prevented from intertwining. That is, a plurality of coil springs 8,
When arranged approximately parallel to each other in the cavity 1, each coil spring 8.8 deviates from a predetermined position, and the coiled portions of adjacent coil springs 8, 8 overlap each other, causing the coil springs 8, 8 to become aligned. As a result, the volume occupied within the cavity 1 decreases, and even if the cavity 1 is compressed, the space necessary for air to flow in and out cannot be maintained.
Furthermore, as the adjacent coil springs 8.8 become entangled and become one, the elasticity of the coil spring 8 hardens, which adversely affects the elasticity of the pillow body A.
Alternatively, the coil spring 8 may bite into the pillow body A and damage the pillow body A, but by wrapping the sheet 9 around the coil spring 8, adjacent coil springs 8 are prevented from overlapping each other in the coiled part. ,
It is possible to provide a pillow that can prevent entanglement, prevent damage due to biting between the coil spring 8 and the pillow main body A, has elasticity over a long period of time, has a restoring force, and has heat dissipation properties.

Note that if the sheet 9 is made of a material with good air permeability, such as gauze, cloth, or flexible wire mesh, air can flow in and out between the inside of the coil spring 8 and the gap 1.

Next, in the invention according to claim 3, a gap l is formed inside the pillow main body A, an air inlet/outlet 2 communicating with the gap l and the outside of the side of the pillow main body A is formed, and a coil spring is formed. By making the coil spring 8 a heat dissipating pillow provided in the cavity 1 so that the direction of expansion and contraction of the coil spring 8 is perpendicular to the horizontal direction of the pillow body A, the vertical direction of the cavity 1 and the coil spring 8 is equal to the expansion/contraction direction, and when the cavity 1 is compressed, the coil spring 8 acts effectively in the expansion/contraction direction.
Particularly, even when the human head is extremely heavy, it is possible to prevent the cavity 1 from collapsing.

Next, in the invention of claim 4, a cavity 1 is formed inside the pillow body A, an air inlet/outlet 2 communicating between the cavity 1 and the outside of the side of the pillow body A is formed, and the cavity A coil spring 8 or a tubular core material 10 is provided in the pillow body A, and grooves 6 that are substantially parallel to the longitudinal direction and have a flat arc shape in cross section are formed on substantially the entire upper surface of the pillow body A, thereby providing a heat dissipating pillow. When the head of the human body comes into contact with the upper surface of the pillow body A, the occiput of the human body fits within the flat arc-shaped groove 6, and the surface of the groove 6 uniformly supports the occiput of the human body, so that the posture during sleep is correct. can be kept correctly.

Next, in the invention of claim 5, a cavity 1 is formed inside the pillow body A, an air inlet/outlet 2 is formed that communicates between the cavity 1 and the outside of the side of the pillow body A, and the cavity 1 is provided with a coil spring 8 or a tubular core material 10, and the upper surface of the pillow body has a small hole 5.5.
By forming a pillow with heat dissipation properties in which a large number of
．． . . . immediately takes in the heat generated by body temperature from the human head into the cavity 1 in the pillow main body A, and at the same time, the air flowing in and out of the cavity 1 from the air inlet 2 enters the human head from the small hole 5. This prevents the temperature of the pillow body A from rising, and at the same time cools the head appropriately, allowing a cool and comfortable sleep.

Next, in the invention of claim 6, a cavity 1 is formed inside the pillow body A, an air inlet/outlet 2 is formed which communicates between the cavity 1 and the outside of the side of the pillow body A, and the cavity The portion 1 is provided with a coil spring 8 or a tubular core material 10, and a groove 6 that is substantially parallel to the longitudinal direction and has a flat circular arc cross section is formed on substantially the entire upper surface of the pillow body A. Since the pillow has heat dissipating properties and has a substantially arcuate constriction 7 formed in at least one of the directions orthogonal to the direction, the constriction 7 appropriately protects the neck of a sleeping human body. That is,
Conventionally, during sleep, the neck of the human body is in the air because the head is supported by a pillow and is not supported, so the M of the neck
The quantitative burden is extremely large, and it actually causes fatigue during sleep.

Therefore, by bringing the head of the human body into contact with the groove 6 and the neck into contact with the constriction 7, the head and neck are brought into contact with the pillow body A.
This provides even support and allows you to sleep in optimal conditions.

Next, in the invention of claim 7, a cavity 1 is formed inside the pillow body A, an air inlet/outlet 2 communicating with the cavity 1 and the outside of the side of the pillow body A is formed, and the cavity By making the pillow having a heat dissipating effect by incorporating the tubular core material 10 having elasticity in the portion 1, it is possible to easily manufacture the pillow having the heat dissipating effect of the present invention.

That is, the tubular core material 10 is made of rubber, synthetic resin, metal, etc., and even if it has moderate elasticity, it is less able to maintain a predetermined shape against external forces than a coil spring. It's easy. Therefore, when pushing the tubular core material 10 into the cavity 1 of the pillow body A, it is easier to push it than the coil spring 8, and the present invention can be manufactured easily.
