[0009] A preferred embodiment of the present invention is described below.

[0010] In the air mat of the present invention, the pump device may include an air pump and a switching valve for switching between supply and exhaust of the air cell. With this configuration, the structure of the mat body can be simplified compared to when the switching valve is provided in the mat body.

[0011] In the stored state of the air mat of the present invention, the main body of the mat may be wound around the outside of the pump device. With this configuration, the main body of the mat can be stored more compactly than when it is folded.

[0012] In the air mat of the present invention, the outer surface of the pump device may be cylindrical. With this configuration, the mat body can be easily stored by wrapping the mat body around the pump device and wrapping the mat body around the pump device. The cylindrical shape of the outer surface of the pump device does not have to be a perfect cylinder. For example, the cylindrical shape of the outer surface of the pump device includes some irregularities on the outer surface of the pump device as long as it is cylindrical overall.

[0013] In the air mat of the present invention, the surface area of ​​the mat body in the stored state may be 1 / 8 or less of the surface area of ​​the mat body in the used state. With this configuration, the mat body can be stored more compactly than if it were folded in half or in thirds.

[0014] <Example> An embodiment of the present invention will be described in detail below with reference to Figs. 1 to 15. As shown in Fig. 1, the air mat M in this embodiment includes a mat body 10, a connection tube (connection portion) 23, and a pump device 30. The mat body 10 and the pump device 30 are connected by the connection tube 23. The pump device 30 supplies compressed air to the air cells 11 via the connection tube 23. Since the pump device 30 is attached externally to the mat body 10, it is possible to prevent vibrations of the pump device 30 from being directly transmitted to a user lying on the air mat M.

[0015] In the following, the upper side (positive side in the Z-axis direction in FIG. 1) of the air mat M in use will be described as the upper side, and the lower side (negative side in the Z-axis direction in FIG. 1) as the lower side in the description of each component. With respect to the mat body 10, the head side (negative side in the X-axis direction in FIG. 1) will be described as the head side, the foot side (positive side in the X-axis direction) as the foot side, the left side (positive side in the Y-axis direction in FIG. 1) as the left side, and the right side (negative side in the Y-axis direction in FIG. 1) as the right side, based on the orientation of a person lying face up on the mat body 10. With respect to the pump device 30, the side connected to the mat body 10 (negative side in the X-axis direction in FIG. 1) will be described as the front side, the opposite side (positive side in the X-axis direction) as the rear side, the positive side in the Y-axis in FIG. 1 as the left side, and the negative side in the Y-axis in FIG. 1 as the right side.

[0016] As shown in Fig. 1, the mat body 10 has a rectangular shape that is long in the X-axis direction. The mat body 10 includes air cells 11 and a cushioning material 14. The upper and lower surfaces of the mat body 10 are flat surfaces without any irregularities. The connection tube 23 extends outward from the right end of the mat body 10 on the foot side. The connection tube 23 is a bundle of five tubes 24. A connector 25 is provided at the terminal portion of the connection tube 23. The connector 25 is connected to a pump device 30.

[0017] The pump device 30 has a cylindrical outer shape as shown in FIG. 1. The length dimension (dimension in the axial direction) of the pump device 30 is greater than the width dimension (dimension in the direction perpendicular to the axial direction). The length dimension of the pump device 30 is approximately half the left-right dimension of the mat body 10. The pump device 30 has a connection part 31 to which the connector 25 is connected. The connection part 31 is provided on the front end side of the pump device 30. By connecting the connector 25 to the connection part 31, each tube 24 and each pipe line 32 of the pump device 30 are connected. The pump device 30 has a remote control light receiving part 33. The remote control light receiving part 33 is provided on the upper side of the connection part 31. The remote control light receiving part 33 receives an infrared signal transmitted from a remote control. The course of the air mat M is set by the signal received by the remote control light receiving part 33. The pump device 30 has a power supply part 34. The power supply part 34 is an AC adapter that is detachable from the pump device 30.

[0018] As shown in Fig. 2, the air cell 11 has a first air cell 11A, a second air cell 11B, and a third air cell 11C. The first air cell 11A and the second air cell 11B are arranged in a region on the head side of the mat body 10. The third air cell 11C is arranged in a region on the foot side of the mat body 10. The air chambers 12 of the first air cell 11A and the second air cell 11B are divided into left and right. The air chamber 12 of the third air cell 11C is divided into a head side and a foot side.

[0019] As shown in Fig. 2, the air cells 11 are disposed on the upper surface of the air cell holding sheet 13. The air cell holding sheet 13 has a rectangular shape that is long in the X-axis direction. The air cell holding sheet 13 is formed of a nonwoven fabric (e.g., felt). The air cells 11 are sewn and fixed to the air cell holding sheet 13.

[0020] 2, the cushion material 14 is disposed above the air cells 11. The cushion material 14 has a rectangular shape that is long in the X-axis direction. The cushion material 14 is made of an elastic material (e.g., urethane foam). The cushion material 14 has the same size as the air cell holding sheet 13.

[0021] As shown in FIG. 2, an anti-noise sheet 15 is disposed under the cushion material 14. The anti-noise sheet 15 is attached to the underside of the cushion material 14 with an adhesive. The anti-noise sheet 15 is rectangular and slightly smaller than the cushion material 14. The anti-noise sheet 15 is large enough to cover all the air cells 11. The anti-noise sheet 15 suppresses the generation of rubbing noise between the cushion material 14 and the air cells 11. The anti-noise sheet 15 is a sheet that is thinner than the cushion material 14 (see FIG. 4). The cushion material 14 and the air cell holding sheet 13 are fixed at the fixing parts by adhesive. The fixing parts between the cushion material 14 and the air cell holding sheet 13 are provided at the end on the head side and the end on the foot side. The middle parts of the cushion material 14 and the air cell holding sheet 13 (area where the air cells 11 are arranged) are not fixed.

[0022] 2, the five tubes 24 constituting the connection tube 23 are disposed on the lower surface of the air cell holding sheet 13. Of the five tubes 24, one each is connected to the left and right air chambers 12 of the first air cell 11A, one each to the left and right air chambers 12 of the second air cell 11B, and one to the air chamber 12 of the third air cell 11C. The one tube 24 connected to the third air cell 11C has a branched end portion that is connected to two air chambers 12. The air chambers 12 of the first air cell 11A and the second air cell 11B expand and contract individually. The two air chambers 12 of the third air cell 11C expand and contract together.

[0023] As shown in FIG. 3, the air cells 11 are symmetrical with respect to a center line L1 in the left-right direction of the mat body 10. The first air cell 11A, the second air cell 11B, and the third air cell 11C are each rectangular in shape that is long in the left-right direction. The mat body 10 has a first region 16, a second region 17, a third region 18, a fourth region 19, and a fifth region 21 in which the air cells 11 are not arranged. The first region 16 is a region between the first air cell 11A and the second air cell 11B. The first region 16 is a strip-like shape extending in the left-right direction. The second region 17 is a region between the second air cell 11B and the third air cell 11C. The second region 17 is a region wider than the first region 16. The third region 18 is a region on both the left and right sides of the air cell 11. The third region 18 extends continuously over the entire length of the mat body 10. A tube 24 is arranged in the third region 18 on the right side. The fourth region 19 is an end region on the head side. The fourth region 19 has a size suitable for placement of a pillow (see FIG. 12). The fifth region 21 is an end region on the foot side.

[0024] 4, the tubes 24 are fixed to the lower surface of the air cell holding sheet 13 by fixing members 22. The fixing members 22 hold the tubes 24 while allowing movement of the tubes 24 in the extension direction. The tubes 24 pass through through holes 28 formed in the air cell holding sheet 13 and are connected to the air cells 11 arranged on the upper surface of the air cell holding sheet 13.

[0025] As shown in Fig. 4, the cushioning material 14 and the air cell holding sheet 13 are covered by an inner cover 26 and an outer cover 27. The inner cover 26 is configured so as not to be easily removed. The outer cover 27 covers the outside of the inner cover 26. The outer cover 27 is freely removable.

[0026] As shown in FIG. 4, the inner cover 26 has an upper surface portion 26A and a lower surface portion 26B. The upper surface portion 26A covers the upper surface of the cushion material 14. The lower surface portion 26B covers the lower surface of the air cell holding sheet 13. The lower surface portion 26B has a thickness dimension greater than that of the upper surface portion 26A. The lower surface portion 26B is formed from an elastic material. The tubes 24 are embedded in the lower surface portion 26B. This makes it possible to prevent unevenness caused by the tubes 24 from being formed on the lower surface of the mat main body 10.

[0027] As shown in FIG. 5, the pump device 30 has components 35 such as an air pump 36, and a pump cover 42 that houses the components 35 therein. The components 35 have the air pump 36, an air tank 37, an electromagnetic valve unit 38, and a circuit board 39. The air pump 36 operates according to commands from the circuit board 39. The air tank 37 stores compressed air intermittently discharged from the air pump 36. By storing air in the air tank 37, the air is continuously supplied to the air cell 11. The electromagnetic valve unit 38 has five electromagnetic valves (switching valves) 41 and a pipe 32. The electromagnetic valve 41 switches between supplying and exhausting air to and from the air cell 11 according to commands from the circuit board 39. The electromagnetic valves 41 are arranged in a line in the axial direction of the pump device 30 (see FIG. 6). The pipe 32 has a first pipe 32A and a second pipe 32B. The first pipeline 32A communicates between the air tank 37 and each solenoid valve 41. The second pipeline 32B is disposed in the connection portion 31. The second pipeline 32B communicates between each solenoid valve 41 and each tube 24. The circuit board 39 controls the operation of the air pump 36 and the solenoid valve 41. This allows the supply and exhaust of air to and from each air chamber 12 of the air cell 11 to be performed appropriately.

[0028] As shown in Fig. 5, the pump cover 42 includes a cover body 43 divided into an upper and lower portion, and a first lid body 44 and a second lid body 45 which close openings at both ends of the cover body 43. As shown in Fig. 1, the cover body 43 is cylindrical. A leg portion 46 is provided on a lower surface 51 of the cover body 43. The first lid body 44 and the second lid body 45 are circular. The first lid body 44 has a connection portion 31.

[0029] As shown in Fig. 5, the cover body 43 has a first cover body 43A and a second cover body 43B. The first cover body 43A and the second cover body 43B are combined vertically. The first cover body 43A and the second cover body 43B have a semicircular cross section. The dimensions of the first cover body 43A and the second cover body 43B in the vertical direction are equal.

[0030] As shown in FIG. 7, the leg 46 extends continuously in the longitudinal direction of the pump device 30. The leg 46 is provided in the longitudinal center of the second cover body 43B. Both front and rear ends of the leg 46 have first inclined surfaces 47. The vertical position of the lower surface 49 of the leg 46 is the same as the vertical position of the lower surface 51 of the second cover body 43B. Both front and rear ends of the lower surface 49 of the leg 46 have first curved surfaces 48. The first curved surfaces 48 are continuous with the lower surface 49 of the leg 46 and the first inclined surfaces 47. The first curved surfaces 48 make both front and rear ends of the leg 46 round. The lower surface 49 of the leg 46 has mounting portions 52 protruding therefrom. The mounting portions 52 are disposed at both front and rear ends of the leg 46.

[0031] As shown in FIG. 8, a pair of legs 46 are provided on the left and right. The left and right legs 46 are symmetrical with respect to a center line L2 in the left-right direction of the pump device 30. A second inclined surface 53 is provided on the outer side of the left and right legs 46 (on the left side of the left leg 46 and the right side of the right leg 46). The second inclined surface 53 is inclined along the outer surface of the cover body 43. The second inclined surface 53 faces the center of the pump device 30 in the left-right direction from the upper side to the lower side. A second curved surface 54 is provided on the inner side of the left and right legs 46 (on the right side of the left leg 46 and the left side of the right leg 46). The second curved surface 54 is curved from the lower surface 49 of the leg 46 to the lower surface 51 of the cover body 43.

[0032] As shown in Fig. 9, the left and right legs 46 extend in parallel. Two mounting sections 52 are provided on each leg 46. The mounting sections 52 are disposed at the front and rear ends of each leg 46. Each mounting section 52 is elongated in the front-rear direction. The left-right dimension of the mounting sections 52 is smaller than the left-right dimension of the legs 46.

[0033] As shown in Fig. 10, the pump device 30 is wrapped in the mat body 10 when stored. This protects the pump device 30. The mat body 10 is wrapped around the outside of the pump device 30. This causes the entire mat body 10 to be curved. This prevents the formation of folding lines at specific locations on the mat body 10 and prevents damage to specific locations on the mat body 10.

[0034] As shown in FIG. 11, the mat body 10 is wound around the pump device 30 two or more times. The surface 61 of the mat body 10 in a state where it is wound around the pump device 30 (referred to as a stored state) is circular, as shown by the two-dot chain line in FIG. 11. The mat body 10 in the stored state has a portion overlapping twice in the inward and outward directions and a portion overlapping three times. The diameter dimension W of the mat body 10 in the stored state is 1 / 6 or less of the longitudinal dimension of the mat body 10 in the unfolded state. In the stored state, the entire upper surface of the mat body 10 is disposed inside the mat body 10. In the stored state, the lower surface of the mat body 10 has a portion disposed inside and a portion disposed outside. The area of ​​the surface (surface 61) disposed outside of the mat body 10 in the stored state is smaller than the area of ​​the surfaces (upper and lower surfaces) of the mat body 10 in the used state. The area of ​​the surface 61 of the mat body 10 in the stored state is 1 / 8 or less of the area of ​​the surfaces (upper and lower surfaces) of the mat body 10 in the used state. The surface area of ​​the mat body 10 in the used state is the combined area of ​​the upper and lower surfaces of the mat body 10.

[0035] Next, an example of the work of storing the air mat M will be described. First, as shown in FIG. 10(A), the pump device 30 is placed on the end of the upper surface of the mat body 10 on the foot side. When the power is off, air is exhausted from all the air chambers 12, and the upper surface of the mat body 10 is flat. The power supply unit 34 is removed from the pump device 30. The pump device 30 is placed so that its axis faces the left-right direction. The pump device 30 is placed on the left side of the mat body 10. The connection tube 23 is placed on the right side of the mat body 10. The connection tube 23 is loosely rolled up.

[0036] Next, as shown in Fig. 10(B), the mat body 10 is rolled up. The pump device 30 and the connection tube 23 are used as core materials, and the mat body 10 is rolled up around the pump device 30 and the connection tube 23. Since the pump device 30 has a cylindrical outer shape, it is possible to prevent the mat body 10 from being damaged when the mat body 10 is rolled up around the pump device 30.

[0037] 10(C), the mat body 10 rolled up in the stored state is attached with the attached fixing band 62. The mat body 10 can be held in the stored state by the fixing band 62. The mat body 10 in the stored state can be placed against a wall or the like.

[0038] When storing or carrying the air mat M for a long period of time, the mat body 10 is placed in a storage bag 63 as shown in FIG. 10(D). The storage bag 63 has a bag body 64, a lid body 65, and a handle 66. The bag body 64 is cylindrical with one end closed. The lid body 65 closes the opening at the other end of the bag body 64. The handle 66 is fixed to the lid body 65. The side of the mat body 10 where the connection tube 23 is located is inserted into the bag body 64 first. The remote control and power supply unit 34 are placed in a pouch or the like, and inserted into the gap in the center of the mat body 10. The lid body 65 is closed. This completes the process of storing the air mat M.

[0039] Next, an example of how to use the air mat M will be described. First, the user puts the air mat M in a stored state into a usable state. First, the user takes out the remote control and the power supply unit 34 from the storage bag 63. Next, the user turns the storage bag 63 sideways, takes out the mat body 10 from the storage bag 63, removes the fixing band 62, and spreads the mat body 10. By spreading the mat body 10, the pump device 30 appears. Here, if unevenness is formed on the upper and lower surfaces of the mat body, the unevenness may be crushed by maintaining the stored state for a long period of time, and the feeling of use of the mat body may change. However, since the upper and lower surfaces of the mat body 10 are flat surfaces, such deformation of the surface can be prevented. Therefore, it is possible to prevent the feeling of use of the air mat M from changing due to long-term storage.

[0040] Next, the user lays the mat body 10 in the installation location. The installation location may be the top surface of a bed mattress, the floor surface, or the top surface of a mattress or futon laid on the floor surface. The user lays the mat body 10 with the top surface of the mat body 10 facing up and the bottom surface facing down. The user connects the connector 25 of the connection tube 23 to the connection part 31 of the pump device 30. The user places the pump device 30 near the mat body 10 and connects the power supply part 34 to the pump device 30 and the outlet. The legs 46 of the pump device 30 allow the pump device 30 to be stably installed without falling over.

[0041] 12, the user lies on his / her back in the center in the left-right direction of the mat body 10. The upper half of the user's body is placed on the upper sides of the first air cell 11A and the second air cell 11B, and the user's legs are placed on the upper sides of the third air cell 11C.

[0042] Next, the user operates the remote control to select a course. The user can operate the remote control while lying on the top surface of the mat body 10. The user selects one of three courses (see Figs. 13, 14 and 15). The first course is a course that provides the user with an environment that is easy for him / her to sleep. The second and third courses are courses that stretch the user's body. In Figs. 13, 14 and 15, the air cells 11 that inflate when air flows in are shown in grey.

[0043] The first course is a zero gravity motion course that relaxes the user by raising and lowering the user's shoulders and waist, as shown in FIG. 13. In the first course, the left and right air chambers 12 of the first air cell 11A are simultaneously inflated and deflated to raise and lower the user's shoulders. In the first course, the left and right air chambers 12 of the second air cell 11B are simultaneously inflated and deflated to raise and lower the user's waist. In the first course, the left and right air chambers 12 of the first air cell 11A and the second air cell 11B are alternately inflated and deflated to rock the user's back from side to side. In the first course, the air chamber 12 of the third air cell 11C is inflated and deflated to relieve tension in the user's legs 46.

[0044] The second course is a whole body stretching course that stretches the muscles and joints of the user's whole body by giving twisting and arching movements to the user's body as shown in FIG. 14. In the second course, the left and right air chambers 12 of the first air cell 11A are simultaneously inflated and deflated to make the user's chest arch. In the second course, the left and right air chambers 12 of the first air cell 11A are alternately inflated and deflated to make the user's shoulders swing from side to side. In the second course, the left and right air chambers 12 of the second air cell 11B are simultaneously inflated and deflated to make the user's waist arch. In the second course, the left and right air chambers 12 of the first air cell 11A and the second air cell 11B are alternately inflated and deflated to make the user's upper body twist. In the second course, the air chambers 12 of the third air cell 11C are inflated and deflated to make the user's legs 46 rise and fall. The second course applies a twisting motion to the user's waist by alternately supplying and exhausting air to and from the left and right air chambers 12 of the second air cell 11B.

[0045] The third course, as shown in FIG. 15, is a beautiful pelvis stretching course that stretches the muscles and joints of the user's waist by twisting and arching the waist. The third course alternately supplies and exhausts air to the left and right air chambers 12 of the second air cell 11B, thereby swaying the user's waist from side to side and giving the waist a twisting motion. The third course simultaneously supplies and exhausts air to the left and right air chambers 12 of the second air cell 11B, thereby arching the user's waist. The second course raises and lowers the user's legs 46 by supplying and exhausting air to the air chamber 12 of the third air cell 11C.

[0046] In each of the first course, the second course, and the third course, the hardness of the air cell 11 can be adjusted to a desired hardness. The hardness of the air cell 11 can be adjusted to three levels: strong, medium, and weak. The operation time of each course differs depending on the hardness of the air cell 11. When the hardness of the air cell 11 is set to strong, the operation time is longer than when the hardness of the air cell 11 is set to weak.

[0047] The power will turn off automatically when the selected course is completed, or if the user presses the stop button on the remote control.

[0048] Next, the operation and effect of the embodiment configured as described above will be described. The air mat M of this embodiment has a mat body 10 and a pump device 30. The mat body 10 is equipped with air cells 11 and cushioning material 14. The pump device 30 supplies air to the air cells 11 via a connection tube 23 extending from the mat body 10. The pump device 30 is wrapped in the mat body 10 in the stored state. With this configuration, the pump device 30 and the mat body 10 can be stored together in a compact manner, making it easy to store and carry.

[0049] The pump device 30 also includes an air pump 36 and an electromagnetic valve 41 that switches between air supply and exhaust of the air cell 11. With this configuration, the structure of the mat body 10 can be simplified compared to when the solenoid valve 41 is provided in the mat body 10.

[0050] Furthermore, when the air mat M is in a stored state, the mat body 10 is rolled up on the outside of the pump device 30. With this configuration, the mat body 10 can be stored more compactly than when it is folded.

[0051] In addition, the outer surface of the pump device 30 is cylindrical. According to this configuration, the mat body 10 can be easily stored by wrapping the mat body 10 around the pump device 30 and around the outside of the pump device 30.

[0052] Furthermore, the surface area of ​​the mat body 10 in the stored state is ⅛ or less of the surface area of ​​the mat body 10 in the used state. With this configuration, the mat body 10 can be stored more compactly than if it were folded in half or in thirds.

[0053] <Other Examples> The present invention is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments are also included within the technical scope of the present invention. (1) The air mat M described in the above embodiment may be equipped with a heater. This allows the air mat to be used comfortably even on cold days. In addition, the air mat may be equipped with a timer setting function. This allows the heater to be turned on according to the time of waking up, making it more convenient to use. (2) The air mat M described in the above embodiment may be profiled on the upper surface of the mat body, which can improve the body pressure dispersion.
