[1. Outline of cushion device and cushion material]

(1) A cushion device included in the present embodiment includes a cushion material having a placement surface for a user, and a mechanism for bending the cushion material in a direction intersecting the placement surface. The plurality of first portions extending in the first direction in the in-plane direction of the mounting surface, and the second portion formed integrally with the first portion between the plurality of first portions and more easily deformable than the first portion. And having.

The cushion device is a device having a cushion, and here is a device having a cushion including a cushion material having a mounting surface of the user. The cushion device is, for example, a mattress, a nursing bed, a massage chair, a chair, a vehicle seat, and the like.

The mechanism for bending the cushion material in the direction intersecting the placement surface is a mechanism for pushing up the cushion material, for example, when the placement surface is the upper surface. The mechanism for pushing up the cushion material includes, for example, an air cell. Instead of the air cell, a cell (fluid cell) filled with a fluid such as an actuator or a liquid may be used. The actuator is, for example, a fluid actuator such as a motor drive actuator, an air cylinder, or a hydraulic cylinder.

Since the first portion and the second portion are formed on the upper surface of the cushion material, a mechanism for bending the cushion material in a direction intersecting the placement surface is provided in the second direction orthogonal to the first direction. The pushed-up force is absorbed by the second part and is not easily propagated. Therefore, the range in which the pushed-up force acts can be local in the second direction. On the other hand, in the first direction, the range in which the pushed-up force acts to function as a rib that propagates the pushed-up force of the first portion is wide. That is, the range in which the cushion material is pushed up can be made different between the first direction and the second direction. Thereby, the user on the upper surface of the cushioning material can effectively perform, for example, “waist twist” or “upper body wake-up”.

(2) Preferably, the second part is a groove formed between the plurality of first parts. By forming the groove portion and the peak portion (line) extending in the first direction on the upper surface of the cushion material, the line is pushed up when the user placed on the upper surface of the cushion material is pushed up by expansion of the air cell or the like. Deform.

(3) Preferably, the cross section orthogonal to the first direction of the first portion is triangular. Thereby, the angle of the surface in contact with the user placed on the upper surface of the cushion material that is deformed as the line is pushed up changes. For this reason, the user can feel the push-up of the cushion material even when it is in contact with the cushion material.

(4) Preferably, the cushion material is divided | segmented into the 2nd direction orthogonal to a 1st direction. Thereby, not only the folding property and the carrying property of the cushion material are improved, but also the propagation of the pushing-up force by the mechanism in the first direction is divided. Thereby, the force of the mechanism to push up can be made to act on a user effectively.

(5) Preferably, the first direction is a height direction of the user placed on the placement surface. Thereby, in the direction orthogonal to the height direction, the force pushed up by the mechanism for bending the cushion material is absorbed by the groove portion of the line and hardly propagates. Therefore, the range in which the pushed-up force acts can be local in the direction orthogonal to the height direction. On the other hand, in the height direction, the range in which the force that is pushed up acts to function as a rib that propagates the force that pushes up the line is wide. That is, the range in which the mattress is pushed up can be made different between the height direction and the direction orthogonal to the direction. Thereby, the user on the upper surface of the mattress can effectively perform, for example, “waist twist” or “upper body wake-up”.

(6) Preferably, the cushion material includes a first layer that constitutes the placement surface, and a second layer that constitutes the back surface side of the placement surface formed of a material harder than the material of the first layer. It is a structure. By molding the first layer with a soft material, it is possible to ensure cushioning for the user by the first layer. By providing the second layer formed of a material harder than the first layer below the first layer, the range pushed up by the underlying push-up mechanism becomes wider than when there is no second layer. As a result, the pressure per unit area applied to the first layer is reduced, and the material of the first layer is less likely to be crushed. Thereby, the force of the mechanism to push up can be made to act on a user effectively. In addition, when the cushion material is composed only of the first layer made of a soft material, the first layer may sink too much and the user may experience a feeling of bottoming out. The feeling of bottoming is a feeling of contact such as a floor, a resin plate, a push-up mechanism, etc., received through a soft layer. The feeling of bottoming is reduced by providing a relatively hard second layer.

(7) Preferably, the first part and the second part are provided in the first layer. Thereby, the force of the mechanism for bending a cushion material can be made to act on a user effectively.

(8) The cushion material included in the present embodiment is a cushion material having a placement surface for the user, and includes a plurality of first portions extending in a first direction in the in-plane direction of the placement surface, and a plurality of first portions. And a second portion that is formed integrally with the first portion between the one portions and that is more easily deformed than the first portion. This cushion material is, for example, for a cushion device having a mechanism for bending the cushion material in a direction intersecting the placement surface. That is, this cushion material is for the cushion device according to any one of (1) to (7). Therefore, when used in this manner, the cushion material has the same effects as the cushion device described in (1) to (7).

[2. Example of cushion device and cushion material]
[First Embodiment]
<Configuration of sleeping device>
FIG. 1 is a perspective view showing an outline of the configuration of the sleep device 100 according to the present embodiment. FIG. 2 is a block diagram showing an outline of the configuration of the sleep device 100. The vertical direction (up and down direction) is the Z direction, one direction perpendicular to the Z direction (left and right direction) is the X direction, and the direction perpendicular to the Z direction and the X direction (front and back direction) is the Y direction. In each direction, a direction toward the + side is referred to as a + direction, and a direction toward the − side is referred to as a − direction.

Referring to the drawing, sleep device 100 is a body support unit, and includes a mat body 10 that is a mattress and a control unit 40 that controls sleep device 100. FIG. 3 is an exploded perspective view of the mat body 10. The mat body 10 is an example of a cushion device.

The mat body 10 is installed on the floor surface or the like so that the upper and lower surfaces are horizontal and the longitudinal direction coincides with the Y direction. The surface in the + Z direction is the upper surface, and the back surface (the surface in the -Z direction) is the lower surface. The mat body 10 supports a user P lying on the upper surface. The mat body 10 includes a urethane layer 17, an air cell 31, a resin layer 16 that is a support member for the urethane layer 17 and the air cell 31, and a cover layer 60 that is a surface member, which are laminated. The urethane layer 17 in the mat body 10 is a cushion material. The upper surface of the urethane layer 17, that is, the upper surface of the mat body 10 is a mounting surface for the user. The placement surface is not limited to being placed directly on the surface by the user, but means a surface on the user side placed on the mat body 10. The cushion material is, for example, a foamed resin having cushioning properties. The foamed resin is, for example, urethane foam, and the urethane layer 17 is made of urethane foam. The air cell 31 and the resin layer 16 are mechanisms for pushing up the urethane layer 17. Pushing up the urethane layer 17 refers to bending the urethane layer 17 in a direction intersecting the upper surface which is the mounting surface. The direction intersecting the upper surface includes + Z direction and generally + Z direction.

The mat body 10 is divided in the X direction so that three portions of the first mat portion 11, the second mat portion 12, and the third mat portion 13 are arranged in order in the Y direction. When the user P lies on the upper surface of the mat body 10 with his / her foot in the + Y direction and the head in the opposite direction (−Y direction), the first mat portion 11 supports the head / shoulder of the user P and the second mat It is assumed that the part 12 supports the trunk and the third mat part 13 supports the legs.

A connecting portion 14 having a notch structure is formed on the lower surface side of the joint surface between the first mat portion 11 and the second mat portion 12. A similar connecting portion 15 is formed on the upper surface side of the joint surface between the second mat portion 12 and the third mat portion 13. Thereby, the mat body 10 can be folded in three.

The third mat portion 13 is formed by laminating a resin layer 16F, a urethane layer 17F, and a cover layer 60 that is a surface member. As shown in FIG. 3, a cover layer for the third mat portion 13 may be further laminated between the urethane layer 17 </ b> F and the cover layer 60. The same applies to the other mat portions. Two air cells 31C and 31To are disposed between the resin layer 16F and the urethane layer 17F.

The second mat portion 12 is formed by laminating a resin layer 16B, a urethane layer 17B, and a cover layer 60. Four air cells 31HiL, 31HiR, 31L, and 31Th are disposed between the resin layer 16B and the urethane layer 17B. The air cells 31HiL and 31HiR arranged in parallel in the X direction are also referred to as air cells 31Hi.

The first mat portion 11 is formed by laminating a resin layer 16H, a urethane layer 17H, and a cover layer 60. Five air cells 31HeL, 31HeR, 31SL, 31SR, and 31B are arranged between the resin layer 16H and the urethane layer 17H. The air cells 31HeL and 31HeR arranged in parallel in the X direction are represented as air cells 31He, and the air cells 31SL and 31SR are represented as air cells 31S.

The air cell 31 is connected to a pump box 32 disposed outside via an air tube 33 and a solenoid valve 34. As an example, a connector box 35 is provided at the end of the third mat portion 13 in the Y direction. The connector box 35 has a connection port for connecting an air tube 33 extending from the pump box 32, and connects the air tube 33 extending from the pump box 32 to the air tube 33 inside the mat body 10 through the connection port. The pump box 32 contains a pump (not shown). In addition to the air tube 33, a distribution line for supplying power to the electromagnetic valve 34 and the control unit 40 is also connected from the pump box 32 to the connector box 35.

FIG. 4 is a view for explaining an arrangement state of the air cells 31 in the mat body 10. Referring to FIG. 4, when user P lies on his back on the upper surface of mat body 10, air cells 31HeL and 31HeR are on the left and right of user P's head, and air cells 31SL and 31SR are below the left and right shoulders. The air cell 31B is under the back, the air cells 31HiL and 31HiR are on the left and right waists, the air cell 31L is below the center of the waist, the air cell 31Th is below the buttocks, the air cell 31C is under the knees, and the air cell 31To is It is assumed to be placed under both calves.

As an example, the control unit 40 is disposed at the end of the third mat portion 13 in the Y direction. The control unit 40 includes a CPU (Central Processing Unit) and a memory 20 (not shown), and controls the sleep device 100 as a whole. The memory 20 stores a program executed by the CPU, and stores data related to the stretch course. Specific examples of the stretch course will be described later.

The control unit 40 has a control unit 43 that controls driving of the pump built in the pump box 32 and opening / closing of the electromagnetic valve 34. When the control unit 43 opens the electromagnetic valve 34 and drives the pump box 32, the air cell 31 connected to the released electromagnetic valve 34 among the plurality of air cells 31 expands, and the urethane layer 17 The portion overlapping the expanded air cell 31 is pushed up. Thereby, a part of the body of the user P lying on the upper surface of the mat body 10 and in contact with the above portion is lifted. The control part 43 can maintain the maximum expansion state of the air cell 31 by continuing to drive the pump. Moreover, the control part 43 stops the drive of a pump after that, and the expansion state of the said air cell 31 is maintained by closing the solenoid valve 34, As a result, the user's P body part was lifted. State is maintained.

When the control unit 43 opens the electromagnetic valve 34 in a state where the pump is stopped, the air in the air cell 31 connected to the released electromagnetic valve 34 among the plurality of air cells 31 is exhausted and expanded. Shrink. As a result, the portion of the urethane layer 17 that overlaps the air cell 31 and has been pushed up returns to its original position. As a result, the part of the user P's lifted body returns to the original position.

The control unit 40 includes a transmission / reception unit 44 that enables transmission / reception of data to / from the smartphone 56. The transmission / reception unit 44 performs wireless communication with the smartphone 56 as an example. Communication between the transmission / reception unit 44 and the smartphone 56 may be wired communication. The smartphone 56 is an example of a device that accepts an input operation on the control unit 40 by the user P. As another example, the smartphone 56 may be a remote controller 50 or the like. Similar to the communication with the smartphone 56, the communication with the remote controller 50 may be a wireless communication or a wired communication. In the case of wired communication, as an example, a communication box 51 is provided at an end portion of the first mat portion 11 in the −Y direction. The communication box 51 has a connection port for connecting a communication cable to an external device such as the remote controller 50, and relays communication with the control unit 40 through the connection port.

<Structure of urethane layer>
FIG. 5 is a schematic view of a part of the urethane layer 17 and shows the horizontally placed urethane layer 17 as viewed from above. Referring to FIG. 5, the urethane layer 17 has a two-layer structure including a first layer 17a on the upper surface side and a second layer 17b on the lower surface side. The first layer 17 a is a layer facing the user P lying on the upper surface of the mat body 10, and the second layer 17 b is a layer in contact with the air cell 31.

On the upper surface of the first layer 17a, a plurality of first portions extending in a first direction in the in-plane direction that is the horizontal direction of the upper surface of the mat body 10, and a first portion between the plurality of first portions are integrated with the first portion. And a formed second portion that is more easily deformed than the first portion. In the example of FIG. 5, the in-plane direction is an arbitrary direction in the XY plane. The first direction is orthogonal to the direction in which the mat body 10 is divided. In the present embodiment, the direction in which the mat body 10 is divided is the X direction, the first direction is the Y direction (FIG. 5), the first portion is a peak portion 18A extending in the Y direction, and the second portion is adjacent. It is the groove part 18B pinched | interposed into the mountain part 18A to do.

Preferably, as shown in FIG. 5, a plurality of groove portions 18B are provided in parallel to the X direction. In the following description, a shape in which a pair of peak portions 18A and groove portions 18B are alternately arranged is also referred to as a line. Since the line is formed on the upper surface of the first layer 17a, when the user P lying on the upper surface of the mat body 10 is lifted by the expansion of the air cell 31, the line is deformed along with the expansion of the air cell 31, thereby The position of the first layer 17a that contacts the user P changes. Since the cross section parallel to the XZ plane of the mountain portion 18A has a triangular shape, the angle of the surface in contact with the user P changes when the position of the first layer 17a in contact with the user P changes. For this reason, the user P can feel the push-up of the mat body 10 even when the user P touches the mat body 10.

The first layer 17a and the second layer 17b are each formed of a foamed resin such as urethane foam. For example, the first layer 17a and the second layer 17b are different in material or density. The material of the second layer 17b is harder than the material of the first layer 17a. By forming the first layer 17a from a soft material, cushioning to the user P by the first layer 17a can be ensured. On the other hand, if there is no second layer 17b and only the first layer 17a is made of a soft material, the material of the first layer 17a is crushed by the expansion of the air cell 31 below, and the upper surface of the mat body 10 is lying on the upper surface. In some cases, the user P is not pushed up. In addition, when a line is formed on the first layer 17a, when the material of the first layer 17a is crushed, the user P is contacted by a surface instead of the line, so that the feeling of pressure on the user P may increase. is there.

In that respect, by providing the second layer 17b formed of a harder material below the first layer 17a, the range pushed up by the expansion of the air cell 31 below is wider than the case where there is no second layer 17b. Become. As a result, the pressure per unit area applied to the first layer 17a is reduced by the expansion of the air cell 31, and the material of the first layer 17a is not easily crushed. Thereby, the behavior of the air cell 31 can be made to act on the user P effectively.

<Control by control unit>
The control unit 43 of the control unit 40 controls driving of the pump and opening / closing of the electromagnetic valve 34 according to the stretch course stored in the memory 20. FIG. 6 is a diagram for explaining a specific example of the stretch course stored in the memory 20 and shows “waist twist”, “cross twist”, and “upper body wake” in the stretch course. FIG. The figure shows the passage of time from the left to the right, and the times t1, t2, t3,. In the figure, the hatched air cell indicates that it has expanded, and the non-hatched air cell indicates that it has not expanded.

Referring to the drawing, the control unit 43 inflates the air cells 31 below the left and right hips and the center of the waist at time t1, expands the air cells 31 below the left waist and the center of the waist at time t2, and performs time t3. The air cell 31 below the right waist and the center of the waist is expanded at time t4, the air cell 31 below the center of the left waist and the waist is expanded at time t4, and the air cell 31 below the center of the right waist and waist is expanded at time t5. By the control from time t2 to t5, the user P is subjected to stretching in which the waist is twisted left and right. In addition, the user P can adjust the position on the upper surface of the mat body 10 so that the waist part coincides with the position lifted by the air cell 31 by the control at time t1.

Referring to the figure, the control unit 43 inflates the air cells 31 under the left and right shoulders and the left and right hips at time t1, and inflates the air cells 31 under the left shoulder and the right waist at time t2 with a “cross twist”. At time t3, the air cell 31 below the right shoulder and left waist is expanded, at time t4, the air cell 31 below the left shoulder and right waist is expanded, and at time t5, the air cell 31 below the right shoulder and left waist is expanded. Under the control from time t2 to t5, the user P is subjected to stretching in which the waist and shoulders are twisted to the left and right opposite to each other. Note that the user P can adjust the position on the upper surface of the mat body 10 so that the left and right shoulders and the left and right waists coincide with the positions lifted by the air cell 31 by the control at time t1.

Referring to the figure, the control unit 43 inflates the air cell 31 under the head left and right, the left and right shoulders, and the back by “upper body wake-up”. By this control, the user P is subjected to a force that allows the upper body to be lifted.

<Effect of Embodiment>
In the mat body 10 included in the sleeping device 100 according to the present embodiment, one or more lines extending in the Y direction are formed in the first layer 17a of the urethane layer 17 that is a cushioning material. 7 and 8 are diagrams for explaining the influence of the lines provided in the urethane layer 17 on the deformation of the urethane layer 17. 7 shows a cross section of the urethane layer 17 parallel to the XZ plane, and FIG. 8 shows a cross section of the urethane layer 17 parallel to the YZ plane.

FIG. 7 shows the behavior of the air cells 31HeL and 31HeR and the deformation of the urethane layer 17H, taking as an example the urethane layer 17H of the first mat portion 11 and the air cells 31HeL and 31HeR arranged below the urethane layer 17H. Are described. Referring to FIG. 7, only one air cell (air cell 31HeL in the case of FIG. 7) of air cell 31HeL and air cell 31HeR arranged in parallel in the X direction expands, and the other air cell (the air cell in the example of FIG. 7). 31HeR) is not expanded, the urethane layer 17 directly above the air cell 31HeL is pushed up with the expansion of the air cell 31HeL in the cross section parallel to the XZ plane including the position directly above the air cells 31HeL and 31HeR of the urethane layer 17. It is done. On the other hand, the pushing-up force due to the expansion of the air cell 31HeL is absorbed in the groove portion 18B of the line in the X direction and hardly propagates. Therefore, the range to be pushed up can be local in the X direction.

FIG. 8 shows, as an example, the urethane layer 17H of the first mat portion 11 and the air cells 31HeR and 31SR arranged in parallel in the Y direction below the behavior of the air cells 31HeR and 31SR and the deformation of the urethane layer 17H. Are described. Referring to FIG. 8, only one of the air cells 31HeR and 31SR arranged in parallel in the Y direction (air cell 31HeR in the case of FIG. 8) expands, and the other air cell (air cell in the example of FIG. 8). 31SR) is not expanded, the urethane layer 17 directly above the air cell 31HeR is pushed up with the expansion of the air cell 31HeR in the cross section parallel to the YZ plane including the position directly above the air cells 31HeR and 31SR of the urethane layer 17. It is done. Further, the peak portion 18A of the line functions as a rib that propagates the force pushed up by the expansion of the air cell 31HeR, and propagates in the Y direction. As a result, the pushed up range is wide in the Y direction.

A configuration shown in FIG. 9 is given as a comparative example in which the range pushed up by the air cell 31 is local in the X direction and wide in the Y direction. The configuration according to the comparative example shown in FIG. 9 is divided into two parts in the X direction, three parts in the Y direction, and the mat parts 11R, 12R, 13R arranged in the Y direction and the mat parts 11L arranged in parallel in the X direction. , 12L, 13L. An air cell 31 is disposed in each mat portion.

The mat main body 10 having the configuration of the comparative example shown in FIG. 9 can divide the propagation of the pushing-up force due to the expansion of the air cell 31 in both the X direction and the Y direction. That is, each mat portion is pushed up by the expansion of the air cell 31, and the pushing-up force does not propagate to the adjacent mat portions.

Even if the mat body 10 has such a structure, it seems that the propagation of the pushing-up force due to the expansion of the air cell 31 can be controlled similarly to the mattress according to the first embodiment. However, in the configuration of FIG. 9, the foldability and portability of the mat body 10 are inferior. For this reason, the mat body 10 according to the present embodiment is configured as shown in FIGS. 1 to 5 in consideration of foldability and portability.

If the pushing-up force due to the expansion of the air cell 31 acts in a wide range in the X direction, the urethane layer 17 may be pushed up in the X direction as a whole in the “waist twist” shown in FIG. As a result, the user P cannot be effectively placed in different postures.

On the other hand, the force that is pushed up by the expansion of the air cell 31 is localized in the X direction (FIG. 7), so that the posture of the user P can be effectively different between the right and left in the “waist twist” shown in FIG. It can be made. That is, at time t2, the left waist and the center of the waist can be lifted and the right waist can be prevented from being lifted. At time t3, the right waist and the center of the waist can be lifted and the left waist can be prevented from being lifted. By repeating this, an effective waist twist is realized.

Further, when the pushing-up force due to the expansion of the air cell 31 is localized in the Y direction, the urethane layer 17 may be pushed only in the vicinity of the air cell 31 in the Y direction only in the “upper half body” shown in FIG. is there. As a result, the user P cannot be lifted in the height direction effectively.

On the other hand, since the pushing-up force due to the expansion of the air cell 31 becomes wide in the Y direction (FIG. 8), the user P can be effectively moved in the height direction in the case of “upper body raising” shown in FIG. Can be lifted.

Furthermore, since the mat body 10 is divided in the direction (X direction) perpendicular to the direction in which the line extends (Y direction), not only the folding and carrying properties of the mat body 10 are improved, but also the air cell 31 Propagation in the Y direction of the pushing-up force due to expansion is interrupted. Thereby, in the “cross twist” shown in FIG. 6, it is possible to effectively make the user P have different postures on the left and right and top and bottom.

The projection 18a is fitted into the recess 42a at the position where the first connector 45 and the second connector 19 are coupled, and the state where the projection 18a is fitted into the recess 42a is maintained by the spring. Thereby, joining with the 3rd mat part 13 and the connector box 35 can be ensured.

<Communication box structure>
FIG. 21A is a schematic diagram showing the structure of the communication box 51. The communication box 51 is a triangular prism-shaped box disposed at the corner 52A of the mat body 10 at the end of the first mat 11 in the Y direction, and FIG. 21A is viewed from above (in the −Z direction). It is a view).

Referring to the drawing, the communication box 51 has a first side surface 51a parallel to the YZ plane and a second side surface 51b parallel to the XZ plane, which are adjacent to each other via the intersection 52. The first side surface 51a and the second side surface 51b are respectively continuous with the first side surface 11a parallel to the YZ plane of the first mat portion 11 and the second side surface 11b parallel to the XZ plane. Accordingly, the first side surface 51a and the first side surface 11a are included in the second side surface 10b parallel to the YZ plane of the mat body 10, and the second side surface 51b and the second side surface 11b are parallel to the XZ plane of the mat body 10. It is included in the side surface 10e. The communication box 51 may be integrated with the first mat portion 11.

The communication box 51 further has an upper surface 51c that is continuous with the upper surface 11c of the first mat portion 11 and a lower surface 51d that is continuous with the lower surface 11d of the first mat portion 11 with the first side surface 51a and the second side surface 51b interposed therebetween. . Therefore, the upper surface 51c and the upper surface 11c are included in the upper surface 10c parallel to the XY plane of the mat body 10, and the lower surface 51d and the lower surface 11d are included in the lower surface 10d.

A part of the intersecting portion 52 in the height direction (Z direction) and excluding the portion 51e having a predetermined thickness from the upper surface 51c constitutes a notch. That is, a range excluding the portion 51e having a predetermined thickness from the upper surface 51c in the height direction of the intersecting portion 52 is cut out by the surface 54A. For example, the surface 54A is a flat surface 54A. The surface 54A may be a curved surface. The flat surface 54 </ b> A is a surface including the extending surface 54. In other words, a portion 51e having a predetermined thickness from the upper surface 51c constitutes a flange portion 51e. The flange 51e protrudes without being adjacent to the first side surface 51a and the second side surface 51b in the range from the extended surface 54 to the intersecting portion 52.

FIG. 21B is a diagram for explaining the extended surface 54 and is a schematic view of the mat body 10 as viewed from above (viewed in the −Z direction). Referring to the figure, intersection 52 is cut out by a plane 54A having an angle θ1 with respect to first side surface 51a and an angle θ2 with respect to second side surface 51b. The range between the first side surface 51a and the second side surface 51b of the flat surface 54A constitutes the extended surface 54. In other words, the extending surface 54 is located in a direction from the intersecting portion 52 toward the diagonal of the intersecting portion 52 of the rectangular mat body 10. A first opening 53a cut out in the plane 54A is formed in the first side surface 51a, and a second opening 53b cut out in the plane 54A is formed in the second side surface 51b. One continuous opening 53 is formed.

Note that the fact that at least a part in the height direction of the intersecting portion 52 is not cut does not mean that the extended surface 54 is manufactured by the notch manufacturing method, and the extended surface 54 is notched. It means that it is a shape. The notched surface, that is, the extended surface 54 is also referred to as a notch.

The extended portion 54 a of the communication cable 57 is disposed in the notch, that is, the extended surface 54. The extension part 54a is, for example, a connector to which the terminal 57a of the communication cable 57 can be attached and detached. In both the first opening 53a and the second opening 53b, the communication cable 57 extending from the extending portion 54a can pass.

Preferably, the angles θ1 and θ2 are 0 to 90 degrees. Thereby, the extended surface 54 makes an angle with respect to each side surface 51a, 51b. Preferably, the angles θ1 and θ2 are 45 degrees or approximately 45 degrees. This corresponds to that the angle formed by the extending direction of the communication cable 57 from the extending portion 54a with respect to the first side surface 51a and the second side surface 51b is 0 to 90 degrees, preferably 45 degrees. Accordingly, even when the communication cable 57 is connected from either of the side surfaces 51a and 51b, the curvature of the communication cable 57 can be increased, and the burden on the communication cable 57 can be suppressed.

Preferably, the extended surface 54 is continuous with the first side surface 51a at the peripheral edge 55a of the first opening 53a, and is continuous with the second side surface 51b at the peripheral edge 55b of the second opening 53b. That is, the extending surface 54 is continuous with no step between the peripheral edges 55a and 55b. Preferably, the extending surface 54 is integrally formed with both side surfaces 51a and 51b. Thereby, the communication cable 57 can be easily connected from either side of the side surfaces 51a and 51b, and molding is facilitated.

<Relationship between connector box and communication box>
When the mat body 10 is provided with two boxes which are the connector box 35 and the communication box 51, they are respectively connected to two sides adjacent to both sides of the same side surface of the mat body 10. Located in the vicinity. That is, referring to FIG. 15, connector box 35 is arranged at corner 36A between first side surface 10a adjacent to + Y side of second side surface 10b, and communication box 51 is adjacent to -Y side. It arrange | positions at the corner | angular part 52A between the 3rd side surfaces 10e. In this example, two extending portions that extend two different cables are provided on the same mat body 10, but two extending portions that extend the same cable have the same mat body 10. May be provided.

<Structure of cover>
FIG. 22 is a diagram illustrating a first example of the passage hole 61 of the cover 60, and is a schematic view of the corner portion 36 </ b> A with the cover 60 attached and the connector box 35 removed. Referring to the drawing, the passage hole 61 is in a range where the peripheral edge portion 61a does not overlap the peripheral edge portion 81a of the joint surface 81 of the third mat portion 13 with the connector box 35 in a state where the cover 60 is mounted on the mat body 10. It is an opening provided in the cover 60. That is, the size of the passage hole 61 is larger than the connector box 35. Therefore, the air tube 33 extended from the extension part 37a can pass through. Accordingly, the cover 60 is not sandwiched when the connector box 35 is attached, and the connector box 35 can be easily attached to and detached from the third mat portion 13.

FIG. 23 is a view showing a second example of the passage hole 61 of the cover 60. Referring to the drawing, in the second example, the pinching allowance 62 that protrudes inwardly from the peripheral edge portion 81 a of the joint surface 81 of the third mat portion 13 in a state where the cover 60 is attached to the mat body 10 in the passage hole 61. Is provided. The pinching allowance 62 exists between the peripheral edge portion 81 a of the joint surface 81 and the peripheral edge portion 18 b of the recess 18. Preferably, the pinching allowance 62 includes side pinching allowances 62a and 62b protruding from the both sides of the joint surface 81 to the inner side (left side and right side) of the peripheral portion 81a, and from the upper side to the inner side of the peripheral portion 81a (lower side). And an upper pinching allowance 62c that protrudes from the top. As a result, the clamping margin 62 is sandwiched between the third mat portion 13 and the connector box 35 when the connector box 35 is mounted. This effectively prevents the cover 60 from being displaced after the connector box 35 is mounted.

When the communication box 51 is a detachable member, the passage hole 65 (see FIG. 15) of the cover 60 provided at a position corresponding to the intersecting portion 52 is also the same as the configuration shown in FIGS. .

The cover 60 is not limited to a so-called box type, and may be a bag shape that includes the mat body 10. In this case, a slide fastener is provided on the side surface of the cover 60 over the entire circumference. Thereby, mounting | wearing to the mat body 10 of the cover 60 becomes easy.

Since the connector box 35 and the communication box 51 are provided at both ends of the second side surface 10b of the mat body 10, preferably the slide fastener over the entire circumference is connected to the second side surface 10b of the cover 60 and the first side. It is divided into a side surface 10a, a third side surface 10e, and a fourth side surface 10f. Thereby, even when the cables are connected to the connector box 35 and the communication box 51, the cover 60 can be easily attached to the mat body 10.

<Effect of Embodiment>
The sleeping device 100 according to the present embodiment, which is an example of a stationary device, is configured such that a cable can be extended from the extending portion to both the first side surface and the second side surface sandwiching the intersection. Part. Specifically, at least part of the height direction of the corner portion of the mat body 10 is cut out by a plane having an angle with respect to both the first side surface and the second side surface, The surface on the outer peripheral side of the mat body 10 in the range sandwiched between the first side surface and the second side surface constitutes an extended surface, and the extended portion is provided on the extended surface. Thereby, even if it has a case where it has only one extension part 37a, the cable can be extended to both the first side face and the second side face.

In the case of the connector box 35, referring to FIG. 18A, the air tube 33 is inserted into the first opening 38a from the first side surface 35a, and the air tube 33 is inserted into the second opening 38b from the second side surface 35b. Thus, the air tube 33 can be inserted into the extending portion 37a which is an opening. In the case of the communication box 51, referring to FIG. 21A, the communication cable 57 is inserted into the first opening 53a from the first side surface 51a, and the communication cable 57 is inserted into the second opening 53b from the second side surface 51b. By inserting, the terminal 57a of the communication cable 57 can be connected to the extending part 54a which is a connector.

Since the cable can be extended from any side surface, the cable can be extended from the other side surface even if the mat body 10 is installed so that one of the side surfaces is in contact with the wall surface. Therefore, restrictions on the installation of the mat body 10 due to the extending direction of the cable can be reduced, and the degree of freedom in the layout of the living room can be significantly improved.

The extending surface 37 is disposed at an angle at which the plane including the extending surface 37 intersects both of the two planes including both side surfaces 35a and 35b, so that the air tube 33 is inserted into either side of the side surfaces 35a and 35b. Even if it is a case, the curvature of the air tube 33 extended from the extension part 37a can be enlarged. Therefore, the burden on the air tube 33 can be suppressed. The same applies to the communication box 51. In particular, since the air tube 33 has hardness and may have a high internal pressure, it becomes difficult to connect when the curvature is small. Furthermore, when the power tube is included in the air tube 33, the size of the air tube 33 is increased, so that the connection becomes difficult when the curvature is decreased. Therefore, it is more effective when the cable is the air tube 33.

As shown in FIG. 18A, the flange portion 35e and the receiving plate 13e are formed so as to protrude toward the intersecting portion 36, whereby an extension portion 37a is provided between the protruding flange portion 35e and the receiving plate 13e. Is sandwiched. Thereby, the connection part to the air tube 33 and the extension part 37a in the connector box 35 is protected. As shown in FIG. 21A, only the collar portion 51e may be formed so as to protrude toward the intersecting portion 52, and may be cut out to the lower surface 11d. Thereby, the communication cable 57 can be easily extended also from the lower surface 11d side in which the opening was formed. In this case, it is preferable that the flange 51e on the upper surface 51c side of the upper surface 51c and the lower surface 51d has a protruding shape. Thereby, even when the user P lies on the upper surface 10c of the mat body 10 and is weighted from above, direct weighting to the extending portion 54a can be prevented. Thereby, damage to the communication cable 57 extended from the extension part 54a can be suppressed.

In addition, when the two extension parts 37a and 54a which each extend two cables are provided in the same mat main body 10, the extension parts 37a and 54a and two side surfaces adjacent to the both sides of the same side surface 10b and By forming in the vicinity of each of the two corners 36A and 52A, the side surfaces 10a, 10e, and 10f other than the side surface 10b side can be installed in contact with the wall surface. Therefore, even when the two extending portions 37a and 54a are provided, it is possible to reduce the restrictions on the installation of the mat body 10 depending on the extending direction of the cable, and to improve the degree of freedom of the layout of the living room. .
