Description

  The present invention relates to a sleeping aid having a floor portion and a ceiling portion and provided with an opening into which a user's head can be inserted.

  Conventionally, a sleeping aid that covers the periphery of the head has been proposed in order to promote sleep at bedtime (see Patent Document 1). Such a sleeping aid can improve sleep state by reducing sound and light reaching the user's head from the surroundings.

Utility Model Registration No. 3156927

  If there is a wall surface just above the user's head, the user can easily feel a sense of pressure. If the user feels a sense of pressure, sleep introduction is hindered, so it is desirable that a space as large as possible be secured above the head. The sleeping aid of Patent Document 1 has a problem that in a configuration in which the upper part of the head is surrounded as shown in FIG. 3, the cloth hangs relatively near the head, so that the user can easily feel a feeling of pressure.

  An object of the present invention is to propose a sleeping aid and a pillow unit capable of improving the comfort at bedtime.

One aspect of the present disclosure made to solve the above-described problem is a floor and an upwardly convex shape, and an internal space is formed between the floor and the user's head. And a ceiling part provided with an opening that can be inserted. In this sleeping aid, in the ceiling portion, the region at the highest position among the inner side surfaces constituting the internal space passes through the center in the left-right direction of the opening as viewed from above, and is orthogonal to the left-right direction. It is comprised so that it may be located on the straight line which has length in the front-back direction.

  Since the ceiling part covers the periphery of the head, the sleeping aid configured in this way can suppress light and sound reaching the head. Moreover, the area | region which exists in the highest position among the inner surfaces which comprise internal space exists on the straight line of the front-back direction which passes the center of the left-right direction (center of the width direction) of opening. In other words, when the head is inserted into the internal space, the upper part of the head in the internal space has a height higher than the surrounding area, so that the user is less likely to feel a pressure.

Therefore, the sleep assisting device can improve the comfort at bedtime. Therefore, the user can fall asleep smoothly and can sleep well by reducing the disturbance of sleep due to sound and light.
Further, in the sleep assisting device described above, when the sleeping assisting device is projected onto a plane whose normal direction is the front-rear direction, the area of the opening on the projection surface is smaller than the area of the internal space on the projection surface. It may be configured as follows.

  Since the opening of the sleep assisting device configured in this way is narrower than the internal space, it is possible to reduce the sound and light entering from the opening when the user inserts the head into the internal space. Moreover, since the internal space is wider than the opening, the user is less likely to feel pressure. Therefore, such a sleeping aid can improve the comfort at bedtime.

  Moreover, you may comprise the said bed assisting tool as follows. The ceiling part has an arcuate support member in which both ends in the length direction are connected to the floor part and the center part is convex upward. When the state in which the support member is not receiving a load from the outside is a first state, the support member is connected to the floor portion at both end portions in the length direction as compared to the first state. The distance between them is approaching, and the second state is a state having a restoring force to return to the first state.

  In the sleeping aid configured in this way, the support member is bent in a so-called arch shape and has a restoring force, and therefore, it is difficult to bend inward. Therefore, since the support member can suppress the shape change of the ceiling portion, the sleeping aid can maintain the shape for a long period while reducing the use of strength parts such as metal wires.

  Further, the support member in the above-described sleeping aid may be a plate-like member, and may be configured such that a cross section by a plane having a normal direction in the vertical direction at the end in the length direction is an arc shape. .

  In the sleep assisting device configured as described above, the shape of the cross section by the plane described above is a strip shape in which the width direction of the plate is long and the thickness direction of the plate is short. And since the cross-sectional shape is arcuate, the support member is bent around the length direction of the plate. Therefore, the strength of the support member is increased, and the shape of the support member can be further prevented from collapsing.

  Further, in the above-described sleeping aid, the support member is a plate-like member, and the two support members are arranged side by side so that the end portions in the width direction intersecting the length direction are adjacent to each other. Furthermore, in the end of one of the support members, a straight line connecting both ends of the length direction in a cross section by a plane having the vertical direction as a normal direction, and the cross section of the other support member in the cross section The two support members may be connected to the floor portion so that a straight line connecting both end portions in the length direction intersects.

  In the sleep assisting device configured in this way, the direction in which the shape of each of the two adjacent support members tends to collapse is different, so that the shape change of one support member can be suppressed by the other support member, and the ceiling portion The shape change can be suppressed to a higher degree.

  Further, in the sleeping aid described above, the ceiling portion includes a first layer having sound absorbing properties, a second layer having light shielding properties, and a covering member covering the first layer and the second layer. It may be configured.

The sleep assisting device configured in this way has high sound absorption and high light shielding properties, so that comfort at bedtime is improved.
Moreover, the other aspect of this indication made in order to solve the problem mentioned above is provided with the sleeping assistance tool of 1 aspect of this indication mentioned above, and the pillow arrange | positioned at the said floor part in the said sleeping assistance tool. This is a pillow unit.

  If it is the pillow unit comprised in this way, there can exist an effect | action and effect similar to the sleeping aid mentioned above.

Embodiments of the present invention will be described below with reference to the drawings.
[Embodiment]
(1) Overall Configuration The sleeping aid 1 of the present embodiment includes a floor portion 11 and a ceiling portion 21 as shown in FIGS. 1 (A) and 1 (B) and FIGS. 2 (A) to 2 (D). It has a hollow dome shape, so-called “kamakura” shape. A space in which the pillow 3 can be placed is formed on the upper side of the floor 11.

The floor 11 is a sheet-like member whose outer edge on the opening 2 side is linear and the other outer edge is curved. The floor portion 11 can be folded freely, but is formed of a material having low stretchability.
The ceiling portion 21 has a convex shape upward, and forms an internal space with the floor portion 11. The lower end of the ceiling part 21 is connected to the floor part 11.

  The sleeping aid 1 is provided with an opening 2 through which the user's head can be inserted into the internal space. The edge portion of the opening 2 includes a portion that is an end portion of the floor portion 11 and a portion that is an end portion of the ceiling portion 21. That is, the opening 2 is a portion where a gap between the floor portion 11 and the ceiling portion 21 is greatly opened.

  The ceiling part 21 includes a front part 22, a central part 23, a left back part 24, and a right back part 25. Each of these parts is configured by covering an elastically deformable plate-like elastic substrate with a covering member. Here, the plate shape means that the dimension in the length direction and the width direction is larger than the dimension in the thickness direction, and the dimension in the thickness direction does not change greatly as a whole.

  As shown in FIGS. 2 (A) and 2 (C), the ceiling portion 21 has a region (region 21a) at the highest position among the inner side surfaces constituting the internal space, as viewed from above. It passes through the center of the direction (the center in the width direction) and is positioned on a straight line (on the straight line 5) having a length in the front-rear direction perpendicular to the left-right direction.

  FIG. 3 shows a projection view of the sleeping assisting device 1 when the plane in which the front-rear direction is the normal direction is the projection plane. The opening 2a in the projection view is accommodated in the internal space 7 in the projection view. Therefore, the area of the opening 2 a is smaller than the area of the internal space 7. Moreover, the opening 2a is smaller than the internal space 7 in the left-right direction mainly in the lower part of the sleeping aid 1 including the connection part of the floor part 11 and the ceiling part 21.

  The elastic base material (31a-31d) of each part is shown in FIG. The elastic base material includes a first support member 31 a constituting the front part 22, a second support member 31 b constituting the central part 23, a left back base material 31 c constituting the left back part 24, and the right back part 25. It is divided into a right rear base material 31d to be configured. For convenience of explanation, a generic term for these members is referred to as an elastic base material 31.

Since each part of the ceiling part 21 is obtained by covering the elastic base material 31 with a covering member, the shape of each part of the ceiling part 21 is substantially the same as the shape of the elastic base material 31.
The elastic base material 31 described in FIG. 4 shows a state in which no external load is applied. In this state, the elastic base material 31 is flat.

  The first support member 31a has a length on one side, and its main surface has a slightly warped shape. Edge portions 37a at both end portions in the length direction (arrow B in the figure) have a curved shape protruding from the center. Although the length in the width direction (arrow C in the figure) intersecting the length direction is shorter than the length direction, it is sufficiently longer than the dimension in the thickness direction.

  The second support member 31b has a length on one side, and its main surface has a slightly bowed shape. Edges 37b at both ends in the length direction (arrow D in the figure) have a curved shape protruding from the center. In the central portion in the length direction, the dimension in the width direction (arrow E in the figure) is smaller than both end portions.

The left back substrate 31c and the right back substrate 31d are substantially fan-shaped and are symmetrical to each other. These are also formed with rectangular through holes 33a and 33b.
FIG. 5 is a cross-sectional view taken along the line AA in FIG. The front part 22, the central part 23, and the left back part 24 are configured by covering the entire periphery of the elastic base material 31 (31 a to 31 c) with a covering member 32. A light shielding sheet 35 having a light shielding property is disposed on the inner side surface of the elastic base material 31. The same applies to the right rear surface portion 25 and the right rear surface base material 31d (not shown in the figure).

That is, the ceiling portion 21 includes a layer of the elastic base material 31, a layer of the light shielding sheet 35, and a covering member 32 that covers the elastic base material 31 and the light shielding sheet 35.
As the elastic substrate 31, foamed polyurethane is used. In addition to this, a sponge-like material such as foamed plastic (polystyrene, polyolefin as an example) can be used, but it is not limited to these as long as it has a suitable elasticity, and various materials can be used. . Since the above-mentioned foamed plastic has an excellent sound absorption property, the sound reaching the user's head can be highly reduced.

  As the light shielding sheet 35, an aluminum sheet obtained by evaporating aluminum on a synthetic resin sheet is used. Various materials can be used as the light-shielding sheet as long as they have light-shielding properties, but they reach the user's head by using sheets with extremely high light-shielding properties such as metal-containing sheets and light-shielding fabrics. It is possible to reduce light to be highly reduced.

The elastic base material 31 is an example of the first layer in the present invention, and the light shielding sheet 35 is an example of the second layer in the present invention.
All the covering members 32 covering the respective parts are connected, and the covering member 32 and the floor portion 11 are also connected. Therefore, the bed assisting tool has the floor portion 11 and each portion constituting the ceiling portion 21 integrated.

  The position in the thickness direction where the front part 22 and the central part 23 are connected is the inner position, that is, the position on the inner space side. Similarly, each of the central portion 23, the left back surface portion 24, and the right back surface portion 25 is connected at an inner position.

  As shown in FIG. 1A and the like, the first support member 31a (front portion 22) and the second support member 31b (center portion 23) are connected to the floor portion 11 at both ends in the length direction. , The central portion has an arc shape protruding upward, that is, a so-called arch shape.

  That is, the first support member 31a and the second support member 31b are different from a state in which no load is received from the outside as shown in FIG. 4, and the distance between both ends in the length direction is made closer by applying the load. And it is connected with the floor part 11 in the state which has the restoring force which is going to return to the state which has not received the load. The floor portion 11 is spread in a planar shape by this restoring force.

  The state having a restoring force means a state in which each supporting member is bent and deformed, and when the connection by the floor portion 11 is released, the degree of bending is reduced by elasticity. Each support member is preferably bent and deformed within the range of elastic deformation.

  In addition, the state which is not receiving the load from the outside as shown in FIG. 4 is an example of the 1st state in this invention, and the state connected as shown in FIG. 1 (A) and FIG. 2 is the 1st state in this invention. It is an example of the state of 2.

  The first support member 31a and the second support member 31b are arranged side by side so that the end surfaces in the width direction are adjacent to each other. Specifically, the end portion 38a shown in FIG. 4A and the end portion 38b shown in FIG. 4B are arranged adjacent to each other.

  FIG. 6 is a cross-sectional view taken along line FF in FIG. This cross-sectional view is a cross-sectional view taken along a plane whose vertical direction is the normal direction, in other words, a plane parallel to the direction in which the floor portion 11 expands. Since this plane is a plane at a position along the floor portion 11, the cross section 41a of the first support member 31a and the cross section 41b of the second support member 31b are cross sections at their lengthwise ends.

  The cross section 41 a and the cross section 41 b are strips that are long in the width direction of each support member and short in the thickness direction, and have an arc shape along the outer edge of the floor portion 11. That is, the front part 22 and the center part 23 are connected to the floor part 11 with the ends bent in an arc shape.

  Further, a straight line G connecting both end portions in the length direction in the cross section 41a and a straight line H connecting both end portions in the length direction in the cross section 41b intersect each other. As a result, as shown in FIG. 2 (C), the sleeping aid 1 has a shape that bulges outward with the above-described intersection as a protruding end.

  FIG. 7 is a diagram illustrating a state in which the sleeping assisting device 1 is folded. First, the front portion 22 is folded inside the central portion 23, and then the center in the length direction of the central portion 23 and the connecting portion of the left back portion 24 and the right back portion 25 are folded into a small group as shown in FIG. be able to.

(2) Effects The sleeping aid 1 of the present embodiment is used by inserting the head from the opening 2 into the internal space formed by the floor 11 and the ceiling 21 so that the ceiling 21 is the head. Since the surroundings are covered, it is possible to reduce the light and sound that reach the head from the outside, and to form an environment where it is easy to sleep.

  Further, the region 21a at the highest position among the inner side surfaces constituting the internal space passes through the center in the left-right direction of the opening 2 as viewed from above, and is located on a straight line having a length in the front-rear direction. Since it is comprised, a big space | interval can be formed between the head and the ceiling part 21, and it can suppress that a user learns a feeling of pressure.

  Therefore, the sleep assisting device 1 can improve the comfort of the user at bedtime, and can promote the user's smooth sleep and the user's sleep. In particular, since the present embodiment has a kamakura shape, a “feeling of wrapping” is born thereby, so that comfort can be further improved.

  The sleep assisting device 1 is configured such that the area of the opening 2a on the projection plane is smaller than the area of the internal space 7 when projected onto a plane whose front-rear direction is the normal direction. That is, the opening 2 is narrower than the widest part of the internal space.

  Therefore, it is possible to reduce the sound and light entering from the opening 2 when the user inserts the head into the internal space. Moreover, since the internal space is wider than the opening, the user is less likely to feel pressure. Therefore, such a sleep assisting device 1 can improve the comfort at bedtime.

  In the above embodiment, the opening 2 has a particularly narrow width in the left-right direction. When narrowing the opening 2, if the height in the vertical direction is simply reduced, the user may feel a strong sense of obstruction. In such a sleeping aid 1, the height of the opening 2 is reduced. Compared to the case, it is convenient that the feeling of occlusion is less likely to be strong.

  Moreover, in the sleeping aid 1 of this embodiment, the 1st support member 31a and the 2nd support member 31b are bent, and are made into arch shape. By being configured in this way, the sleeping aid 1 can suppress the shape change of the ceiling portion 21 and can maintain the shape for a long period of time.

  The reason can be estimated as follows, for example. Each supporting member has a restoring force to return to a flat plate shape. The floor portion 11 is connected to a support member, applies a reaction force of the restoring force to the support member, and pushes the central portion of the support member upward. In this manner, the central part is pushed up by the reaction force, thereby suppressing the sag of the central part due to gravity.

  Moreover, as for the said sleeping aid 1, the lower end part connected with the floor part 11 in the 1st support member 31a and the 2nd support member 31b is curving in the arc shape centering on a length direction. By bending in this way, the strength of each support member is increased, and the shape of the ceiling portion 21 can be further prevented from collapsing.

  Moreover, since the said sleeping assistance tool 1 differs in the length direction of the cross section in the lower end part of the 1st support member 31a arrange | positioned adjacently and the 2nd support member 31b, the direction in which they are easy to break shape differs. Therefore, the shape change of one support member can be suppressed by the other support member, and the shape change of the ceiling part 21 can be suppressed to a higher degree.

  Moreover, in the said sleeping assistance tool 1, since the width | variety of the center part of the 2nd support member 31b is small in the length direction, as a result of being able to implement | achieve weight reduction of a center part, the drooping of the ceiling part 21 can be suppressed. .

  Moreover, in the said sleeping assistance tool 1, since it becomes easy for air to flow through the through-holes 33a and 33b, the excessive raise of internal temperature and a breathlessness can be suppressed. Since the through holes 33a and 33b are formed on the opposite side of the opening 2, the through holes 33a and 33b are located in the direction of the crown when in use. Therefore, the light entering from the through holes 33a and 33b is difficult to reach the eyes.

  Moreover, the pillow unit composed of the sleeping aid 1 and the pillow 3 can exhibit the same operations and effects as the sleeping aid 1 described above. In that case, the pillow 3 may be formed integrally with the floor portion 11 or the like, or may be configured to be detachable.

[Other Embodiments]
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various forms can be taken as long as they belong to the technical scope of the present invention.

  (A) In the said embodiment, although the 1st support member 31a and the 2nd support member 31b illustrated the structure which is flat form in the state where the load is not applied, the shape may not be flat form. For example, even if the shape is curved in an arch shape in the state where no load is applied, if the degree of bending is further increased and the state has a restoring force when connected to the floor portion 11, There is an effect.

  (B) In the said embodiment, although the structure which maintains a dome shape with the elastic base material 31 was illustrated, the sleeping aid 1 may have members, such as a column for maintaining a shape. However, by using the support member as in the present invention, it is possible to reduce the amount of the member necessary for maintaining the shape.

  (C) In the above embodiment, the end portions of the first support member 31a and the second support member 31b are connected to the floor portion 11 so as to form an arc shape, and the length directions of the cross sections 41a and 41b are different. Was illustrated. However, these features may have only one or none of them.

  (D) In the above-described embodiment, the sleep assisting device 1 has been illustrated with a configuration in which the respective units are integrated, but may be configured to be splittable. For example, the structure by which each part of the floor part 11 and the ceiling part 21 is connected with a hook-and-loop fastener or a line fastener may be sufficient.

  (E) In the above-described embodiment, the sleep assisting device 1 has a configuration having a so-called kamakura shape in which a portion other than the opening has a curved shape, but may have a shape other than that. For example, a rectangular box shape may be used, and in this case, it may be configured such that the highest region of the internal space exists on a straight line in the front-rear direction passing through the left and right center of the opening. In addition, when the sleeping aid is configured to have a substantially hemispherical shape (a dome shape that is substantially circular in a top view) except for the opening as in the above embodiment, the load applied to the ceiling portion 21 is dispersed. And deformation of the shape can be suppressed.
