Description

Hydraulic massage device

The present invention relates to a hydraulic massage device that gives hydraulic stimulation to a user lying on a support sheet.

Conventionally, there has been known a hydraulic massage device that gives a user lying on a support sheet stimulation by hydraulic pressure (for example, Patent Document 1). In this type of massage device, the opening of the water tank is covered with a support sheet to form a sealed space, and this space is filled with a liquid such as water. Furthermore, an injection nozzle is disposed at the bottom of the water tank, and liquid is injected from the injection nozzle toward the support sheet. In this way, the user lying on the support sheet is given hydraulic stimulation through the support sheet, and the user is massaged.

JP 2010-253288 A

In the hydraulic massage device having the above configuration, the support sheet is made of a material rich in elasticity in order to effectively stimulate the user. For this reason, the support sheet bends relatively easily when the upper surface is pressed, and a certain amount of labor is required for the user to lie on the support sheet alone.

Also, when the user is an elderly person or the like, when the support sheet is greatly bent beyond the user's expectation when seated, the user may lose balance and hinder smooth operation. . For this reason, although assistance of an attendant is needed for an elderly person, even if it receives assistance of an attendant, an elderly person will take comparatively big labor.

In view of the above problems, an object of the present invention is to provide a hydraulic massage device that can effectively reduce the burden on the user when lying on a support sheet.

The first aspect of the present invention relates to a hydraulic massage device. The hydraulic massage apparatus according to this aspect includes a water tank having an open upper surface, a support sheet that covers the upper surface of the water tank, and an injection unit that is disposed in the water tank and injects liquid in the water tank toward the support sheet. And a support portion that is installed in the water tank and supports at least a part of the peripheral portion of the support sheet from the lower surface side.

According to the hydraulic massage device according to this aspect, since a part of the support sheet is supported from the lower surface side by the support part, this part is difficult to bend even if the user is seated. Thereby, since a user can sit down on a support sheet smoothly, the burden at the time of a user lying on a support sheet can be reduced effectively.

In the hydraulic massage device according to this aspect, the support portion may include a bag member that expands when gas is fed into the inside.

In this case, the hydraulic massage device according to this aspect may further include a gas introduction unit that sends the gas into the bag member. Here, when the gas is introduced into the bag member by the gas introduction portion, the upper portion of the bag member may be in contact with the lower surface of the support sheet. If it carries out like this, since a support sheet is directly supported by a bag member, the structure of a support part can be simplified. Further, when the gas is introduced into the bag member and swells, the volume in the water tank increases by the amount of the gas sent into the bag member, but since this volume increase is suppressed by the support sheet, the pressure in the water tank increases. It is done. For this reason, the pressure of the part of the support sheet which is not supported by the support part increases, and the support sheet is difficult to bend even if the user is seated or hands on this part. Thereby, a user's burden at the time of lying on a support sheet can be reduced still more effectively.

In this case, the hydraulic massage device according to this aspect may further include a gas removing unit that extracts the gas from the inside of the bag member. Here, when the gas is extracted from the bag member by the gas removing unit, the bag member is stagnated and the upper portion of the bag member is separated from the lower surface of the support sheet. In this case, for example, when massage is performed, the bag member is folded and separated from the lower surface of the support sheet, so that the portion of the support sheet supported by the bag member is supported by the bag member in the same manner as the other portions. No state. Therefore, in the case of a massage, a part becomes hard and does not give the user a sense of incongruity, and a comfortable massage effect can be provided to the user. Moreover, since the pressure in a water tank becomes low by stiffening a bag member in this way, a support sheet becomes easy to bend. Thereby, it becomes easy for a user to be buried in a support sheet, and the massage effect with respect to a user can be heightened.

In this case, the hydraulic massage device according to this aspect may further include a control unit that controls the gas introduction unit and the gas removal unit. Here, at least when the user is seated on the support sheet, the control unit introduces the gas into the bag member to bring the upper portion of the bag member into contact with the lower surface of the support sheet, and at least massage In operation, the gas may be extracted from the bag member to separate the bag member from the lower surface of the support sheet. In this way, a comfortable massage effect can be provided to the user while proceeding with smooth seating.

In the hydraulic massage device according to this aspect, the support portion may further include a support body interposed between the bag member and the support sheet. Here, when the bag member is filled with the gas, the upper portion of the support may be in contact with the lower surface of the support sheet. If it carries out like this, compared with the case where it supports directly with a bag member, a support sheet can be supported more stably. Therefore, the burden on the user when sitting can be more effectively reduced.

The second aspect of the present invention relates to a hydraulic massage apparatus that performs massage by spraying a liquid filled in a sealed space onto a user. The hydraulic massage device according to this aspect includes a support sheet that is disposed above the liquid and supports a user, an ejection unit that ejects the liquid filled in the sealed space toward the support sheet, and the sealing A pressure adjusting unit that changes the pressure in the space.

According to the hydraulic massage device according to this aspect, when the pressure in the sealed space is increased by the pressure adjusting unit, the support sheet is difficult to bend even if the user is seated. Thereby, since a user can sit down on a support sheet smoothly, the burden at the time of a user lying on a support sheet can be reduced effectively.

In the hydraulic massage apparatus according to this aspect, the pressure adjusting unit may include a bag member installed in the sealed space, and the bag member may be configured to expand when gas is fed into the inside. If it carries out like this, gas will be sent in and a bag member will swell and the pressure in sealed space will be raised. For this reason, the pressure concerning a support sheet increases and even if a user seats, a support sheet becomes difficult to bend. Thereby, the burden at the time of a user lying on a support sheet can be reduced effectively.

In this case, the pressure adjusting unit may further include a gas introducing unit that sends the gas into the bag member and a gas removing unit that extracts the gas from the bag member. If it carries out like this, since the pressure in sealed space will become low by stiffening a bag member in the case of a massage, a support sheet will become easy to bend. Thereby, it becomes easy for a user to be buried in a support sheet, and the massage effect with respect to a user can be heightened.

In the hydraulic massage apparatus according to the present aspect, the pressure adjusting unit includes a control unit that controls the pressure in the sealed space, and the control unit is configured so that at least when the user is seated on the support sheet, The pressure in the sealed space may be increased, and at least during a massage operation, the pressure in the sealed space may be reduced compared to when sitting. In this way, a comfortable massage effect can be provided to the user while proceeding with smooth seating.

As described above, according to the present invention, it is possible to provide a hydraulic massage device that can effectively reduce the burden on the user when lying on a support sheet.

FIG. 1A is an exploded perspective view showing a configuration of a water bed 1 according to the present embodiment. For convenience, FIG. 1A shows X, Y, and Z axes orthogonal to each other. The XY plane is parallel to the horizontal plane, and the Z-axis direction is the vertical direction.

As shown in FIG. 1A, the water bed 1 includes a water tank 10, a support frame 20, and an airbag 30.

The water tank 10 is composed of a vertically long hull having an open upper surface, and has a symmetrical shape in the X-axis direction. In plan view, the upper surface of the aquarium 10 has a rectangular outline with rounded corners. The water tank 10 is provided with two shelves 10a parallel to the XY plane at a predetermined depth from the upper surface, and a bottom 10b parallel to the XY plane at a position deeper than these shelves 10a.

Further, a hole 14 (see FIG. 3A) is provided in the inner wall surface on the X axis negative side, and a hole 15 (see FIG. 3A) is provided on the shelf 10a on the X axis negative side (see FIG. 3A). a)) is provided. Further, the thermistor 16 is inserted into the water tank 10 from the side surface on the Y axis positive side, and the temperature detection part of the thermistor 16 is positioned inside the water tank 10. The

holes

12 and 13 are connected to a suction port and a discharge port of a temperature controller 80 (see FIG. 2B), which will be described later, through a pipe, and the

holes

14 and 15 are respectively connected to a pump 40, which will be described later. It connects with the suction inlet and discharge outlet of (refer Fig.2 (a)) via piping.

The support frame 20 is composed of a rectangular frame with an open upper surface. The contour of the upper surface of the support frame 20 is slightly smaller than the contour of the upper surface of the water tank 10. Moreover, the dimension of the support frame 20 in the depth direction is larger than the dimension of the water tank 10 in the depth direction. Therefore, when the water tank 10 is fitted into the support frame 20 from above, the outer peripheral edge of the water tank 10 is placed on the upper frame of the support frame 20, and the water tank 10 is supported by the support frame 20. A support plate 21 is attached to the support frame 20 by welding. The support plate 21 is provided with a pump 40 and a circuit board 50 (see FIG. 2A), and a pump 70 and a temperature regulator 80 (see FIG. 2B).

The airbag 30 is a bag member that is inflated when the inside is filled with gas (air in the present embodiment). A tube 31 connected to the inside of the airbag 30 is connected to the end portion of the airbag 30 on the Y axis positive side. The air bag 30 is inflated as shown in FIG. 1 (b) when air is sent into the inside through the tube 31 in the stiff state as shown in FIG. 1 (a). At this time, the lower surface 32 and the upper surface 33 of the airbag 30 change from a state where they are close to each other as shown in FIG. 1A to a state where they are separated from each other as shown in FIG.

In FIG. 1A, the shape of the airbag 30 in a folded state is illustrated so that the side surface is folded for convenience, but may be a shape other than the shape shown in FIG. . For example, the shape of the airbag 30 in a stagnation state may be a shape in which the lower surface 32 and the upper surface 33 overlap and the side surface extends outward from the lower surface 32 and the upper surface 33.

When the user sits on the water bed 1 and lies down, the airbag 30 is in a bulged state (hereinafter referred to as “maximum state”) as shown in FIG. In addition, the air bag 30 is in a state of being massaged to the minimum (hereinafter referred to as “minimum state”) as shown in FIG. The operation of the water bed 1 will be described later with reference to FIGS. 5 (a) to 8 (b).

During assembly, the water tank 10 is fitted into the support frame 20 from above. Subsequently, the lower surface 32 of the airbag 30 is fixed to the shelf 10a on the X axis positive side with an adhesive, and the tube 31 is passed through the hole 11 from the upper side. The gap between the tube 31 and the hole 11 is filled with putty or the like. Thus, after the water tank 10 is attached to the support frame 20 and the airbag 30 is attached to the water tank 10, the pump 40, the circuit board 50, the pump 70, and the temperature controller 80 are installed on the support frame 20.

FIG. 2A is a perspective view showing a state in which the pump 40, the circuit board 50, the pump 70, and the temperature controller 80 are installed on the support frame 20, and FIG. It is a side view which shows the state of a) typically. In addition, in FIG.2 (b), illustration of the support frame 20 is abbreviate | omitted for convenience.

Referring to FIG. 2 (a), the pump 40 is installed on the support plate 21. The intake port 41 and the discharge port 42 of the pump 40 are respectively connected to the holes 14 and 15 (see FIG. 3A) of the water tank 10 through piping. The circuit board 50 is installed on the support plate 21 while being stored in the storage box 60. Specifically, the storage box 60 is installed on the support plate 21, and the circuit board 50 is stored in the storage box 60. The storage box 60 also stores electrical systems other than the circuit board 50.

Referring to FIG. 2 (b), the pump 70 is installed on the support plate 21. The vent 71 of the pump 70 is connected to the valve 72. The valve 72 is configured to be switchable between a state in which air passes (hereinafter referred to as “open state”) and a state in which air does not pass (hereinafter referred to as “sealed state”) by being electrically driven. In the non-driven state, the open state or the sealed state can be maintained. The valve 72 is connected to the tube 31 of the airbag 30 via a pipe. The pump 70 includes a positive pressure source 70a and a negative pressure source 70b (see FIG. 4). The positive pressure source 70 a is configured to be able to send air into the interior of the airbag 30, and the negative pressure source 70 b is configured to be able to extract air from the interior of the airbag 30.

The temperature controller 80 is installed on the support plate 21. The intake port 81 and the discharge port 82 of the temperature controller 80 are connected to the hole 12 and the hole 13 of the water tank 10 through piping, respectively. The temperature controller 80 includes a pump (not shown), a heating unit, a cooling unit, and a pipe, and heats the liquid (water in the present embodiment) taken from the hole 12 in the heating unit, or Then, after cooling in the cooling section, it is discharged from the hole 13. Whether heating or cooling is performed is determined by the CPU 51 (see FIG. 4) of the circuit board 50 so that the temperature detected by the thermistor 16 becomes a predetermined temperature.

After the above assembly is performed, the injection unit 90 (see FIG. 3A) is installed in the water tank 10.

FIG. 3A is a plan view schematically showing a state in which the injection unit 90 is installed in the water tank 10. In FIG. 3A, the support frame 20 and the airbag 30 are not shown for convenience.

The injection unit 90 includes two pulleys 91, a belt 92 stretched between the pulleys 91, a moving plate 93 coupled to the belt 92 and supported so as to be movable in the Y-axis direction, and rotatable on the moving plate 93. And two supported rotors 94. The two rotors 94 are each provided with an injection port 95 for injecting water. Water is supplied to the injection port 95 via a water supply port (not shown). The water supply port is connected to the hole 15 of the water tank 10 through an elastically deformable pipe 96. Therefore, when the pump 40 is driven, water taken from the hole 14 is jetted from the jet port 95.

One of the two pulleys 91 is driven by a motor (not shown). As a result, the two rotors 94 move in the Y-axis direction together with the moving plate 93, and the two rotors 94 rotate on the moving plate 93 around the Z axis. Thereby, the injection port 95 rotates around the Z axis. Thus, the injection port 95 is moved in the Y-axis direction while rotating.

After that, a support sheet 110 (see FIG. 3B) is attached to the water tank 10 so as to cover the entire upper surface of the water tank 10. Moreover, the housing | casing 120 (refer FIG.3 (b)) is installed so that the circumference | surroundings of the support frame 20 may be covered. Thus, the assembly of the water bed 1 is completed.

FIG. 3B is a perspective view showing the water bed 1 after assembly.

The support sheet 110 is provided with a water supply hole 111 and a lid 112 that closes the hole 111. The support sheet 110 is made of a material rich in elasticity, and is attached to the water tank 10 so that there is no liquid leakage. In addition, the housing 120 is provided with a display input unit 130 for receiving an input by the operator and displaying the operation state of the water bed 1. The display input unit 130 is configured by a touch panel, for example. The display input unit 130 is connected to the circuit board 50 (see FIG. 2A) by electrical wiring.

After the water bed 1 is assembled as described above, water is supplied from the hole 111 to the water tank 10 until the water tank 10 becomes full. Thereafter, the hole 111 is closed by the lid 112. In this way, the sealed space formed by the water tank 10 and the support sheet 110 is filled with water.

FIG. 4 is a block diagram showing the configuration of the water bed 1.

The circuit board 50 is provided with a CPU 51, a memory 52, and an interface 53. The CPU 51 controls each unit according to a program stored in the memory 52. The CPU 51 outputs a control signal to each unit through the interface 53 and receives a signal from each unit through the interface 53. The pump 70 includes a positive pressure source 70 a and a negative pressure source 70 b, and air can be taken in and out of the airbag 30.

FIGS. 5A and 5B are flowcharts showing control by the CPU 51. FIG. 6A and 6B are views showing a state where the user is seated on the water bed 1 and a state where the user lies on the water bed 1.

Referring to FIG. 5A, when the operator performs an operation to turn on the power of the water bed 1 with respect to the display input unit 130 (S101), the CPU 51 opens the valve 72 and turns on the pump 70. The driving of the positive pressure source 70a is started (S102). Thereby, air is sent into the airbag 30. As will be described later, when the power of the water bed 1 is turned off, air is extracted from the inside of the airbag 30. Therefore, when the power of the water bed 1 is turned on, the air inside the airbag 30 is not air. Is not included.

Subsequently, when a predetermined time elapses after the driving of the positive pressure source 70a is started (S103: YES), the CPU 51 closes the valve 72 and stops driving the positive pressure source 70a (S104). As a result, the airbag 30 reaches its maximum state as shown in FIG. 1B, and the upper surface 33 of the airbag 30 abuts on the lower surface of the support sheet 110. Then, the CPU 51 displays a message indicating that it is possible to get on and off the display input unit 130 (S105).

In addition, the time for driving the positive pressure source 70a is a time until the airbag 30 is changed from the minimum state to the maximum state by the positive pressure source 70a, and this time is stored in the memory 52 in advance. Further, the height of the airbag 30 is set so that the upper surface 33 of the airbag 30 comes into contact with the lower surface of the support sheet 110 when the airbag 30 reaches the maximum state.

Next, the first user arrives, and this user sits on the front side of the center of the support sheet 110 as shown in FIG. 6A, and on the support sheet 110 as shown in FIG. 6B. Lying down. Thereafter, the operator inputs a massage start instruction to the display input unit 130. When a massage start instruction is input (S106: YES), the CPU 51 opens the valve 72 and starts driving the negative pressure source 70b (S107). Thereby, air is extracted from the inside of the airbag 30. Subsequently, when a predetermined time has elapsed after the drive of the negative pressure source 70b is started (S108: YES), the CPU 51 closes the valve 72 and stops the drive of the negative pressure source 70b (S109). As a result, the airbag 30 is in the minimum state as shown in FIG. 1A, and the upper surface 33 of the airbag 30 is separated from the lower surface of the support sheet 110. And the drive of the injection part 90 is started (S110) and the massage with respect to a user is performed.

The time for driving the negative pressure source 70b is a time until the airbag 30 is changed from the maximum state to the minimum state by the negative pressure source 70b, and this time is stored in the memory 52 in advance. When the airbag 30 is in the minimum state, the upper surface 33 of the airbag 30 is in a state of being most separated from the lower surface of the support sheet 110. At this time, since the airbag 30 is small, even if the injection unit 90 is driven, the swing of the airbag 30 due to the water flow generated in the water tank 10 is suppressed.

Next, when the massage for the user is completed, the operator inputs a replacement instruction to the display input unit 130 in order to replace the user. When the replacement instruction is input (S111: YES), the CPU 51 returns the process to S102. Thereafter, the processing of S102 to S104 described above is performed, and a message indicating that the airbag 30 is in the maximum state and that it is possible to get on and off in S105 is displayed.

When confirming the message displayed in S105, the operator urges the user lying on the support sheet 110 to get off the water bed 1. Thus, the user sits on the front side of the support sheet 110 from the state lying on the support sheet 110 as shown in FIG. get off. Then, when the next user arrives and this user lies on the support sheet 110 as shown in FIGS. 6A and 6B, the operator starts massage on the display input unit 130. An instruction is input (S106: YES). In this way, the processes after S107 are performed, and the processes of S102 to S111 are repeated.

Referring to FIG. 5B, when the operator performs an operation to turn off the power of the water bed 1 with respect to the display input unit 130 (S201: YES), the CPU 51 starts the processes after S202. The operation for turning off the power of the water bed 1 can be accepted by the display input unit 130 only when no massage is performed, that is, when the airbag 30 is in the maximum state.

When an operation to turn off the power is performed (S201: YES), the CPU 51 displays a message on the display input unit 130 for confirming to the operator whether the power-off process can proceed (S202). The operator confirms that there is no user on the water bed 1, and inputs an instruction to proceed with the power-off process to the display input unit 130. When an instruction to proceed with the power-off process is input (S203: YES), the CPU 51 performs the same process as S107 to S109 (S204 to S206) to bring the airbag 30 to the minimum state. Thereafter, the CPU 51 executes a shutdown process and turns off the power (S207).

The operation of the display input unit 130 may be performed by the user as well as by the operator as described above. When the user is an elderly person, it is desirable that the worker assists the user when getting on and off the water bed 1.

<Effect of Embodiment>
According to the present embodiment, the following effects can be achieved.

When the user gets on and off the water bed 1, as shown in FIG. 1 (b), the airbag 30 is brought into a maximum state. Thereby, the lower surface side of the support sheet 110 near the X axis positive side and the center in the Y axis direction (sitting position) is supported by the upper surface 33. Therefore, the support sheet 110 becomes difficult to bend at the sitting position, and the user can sit on the support sheet 110 smoothly and lie on the support sheet 110.

FIGS. 7A to 7C are views schematically showing the state of the airbag 30 and the support sheet 110. FIG.

Immediately after the power is turned on and during massage, the airbag 30 is in a minimum state as shown in FIG. From this state, air is sent into the airbag 30 and the airbag 30 is brought to a maximum state as shown in FIG. As a result, the upper surface 33 of the airbag 30 contacts the lower surface of the support sheet 110, and the lower surface of the support sheet 110 is supported by the upper surface 33 at the seating position P <b> 1 where the user sits on the support sheet 110. In this state, when the user who is going to perform massage sits on the support sheet 110 as shown in FIG. 7C, the support sheet 110 becomes difficult to bend at the seating position P1. Accordingly, the user can smoothly sit at the sitting position P1, and therefore, the burden on the user lying on the support sheet 110 can be effectively reduced.

Also, when the massage is finished and the user gets off the water bed 1, the air is sent into the airbag 30 and the airbag 30 is brought to the maximum state. Accordingly, the lower surface of the support sheet 110 is supported by the upper surface 33 at the seating position P1. Therefore, the user lying on the support sheet 110 can smoothly sit at the sitting position P1 and get off the water bed 1.

Further, the lower surface of the support sheet 110 is supported by the upper surface 33 of the airbag 30, and the upper surface 33 is moved up and down by taking air into and out of the interior of the airbag 30. Thereby, the lower surface of the support sheet 110 can be supported by a simple configuration without using a complicated mechanism.

In addition, air is sent into the airbag 30 as described above, and the airbag 30 is changed from a stagnation state as shown in FIG. 7A to a swelled state as shown in FIG. 7B. When changed, the volume in the water tank 10 is increased by the amount of air fed into the airbag 30, while this increase in volume is suppressed by the support sheet 110. Thereby, since the pressure in the water tank 10 is increased, the pressure of the portion of the support sheet 110 that is not supported by the airbag 30 is increased, and the support sheet 110 is not easily bent even if the user is seated or hands on this portion. Become. Thereby, the burden on the user when lying on the support sheet 110 and when getting off the water bed 1 can be more effectively reduced.

Further, during the massage, as shown in FIG. 1 (a), the airbag 30 is in a minimum state. Accordingly, the upper surface 33 of the airbag 30 moves downward, and the lower surface side of the seating position of the support sheet 110 is not supported by the upper surface 33, so that the support sheet 110 at the seating position is soft as in the other positions. Become. Therefore, during massage, a part of the support sheet 110 becomes hard and does not give the user a sense of incongruity, and a comfortable massage effect can be provided to the user.

FIGS. 8A and 8B are diagrams schematically showing the state of the airbag 30 and the support sheet 110. FIG.

Immediately after the user lies on the support sheet 110, the upper surface 33 of the airbag 30 is in contact with the lower surface of the support sheet 110 as shown in FIG. At this time, since the portion on the X axis positive side of the recumbent position P2 where the user lies is supported from the lower surface side by the airbag 30, this portion is harder than the other portions. In the state of FIG. 8A, the user's right hand is hung on this hard part, so the user feels uncomfortable on the right hand part. However, during the massage operation, air is extracted from the inside of the airbag 30 from this state, and the airbag 30 is brought into the minimum state as shown in FIG. Thereby, the upper surface 33 of the airbag 30 is separated from the lower surface of the support sheet 110, and the lower surface of the support sheet 110 at the lying position P <b> 2 is not supported by the upper surface 33. Therefore, at the time of a massage operation, a part of the support sheet 110 at the recumbent position P2 becomes hard and does not give the user a sense of incongruity, and a comfortable massage effect can be provided to the user.

Moreover, since the pressure in the water tank 10 becomes low by massaging the airbag 30 as shown in FIG. 8B during the massage, the support sheet 110 is easily bent. Thereby, it becomes easy for a user to be buried in the support sheet 110, and the massage effect with respect to a user can be heightened.

<Example of change>
While the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made to the configuration example of the present invention.

For example, in the above embodiment, the airbag 30 is installed by fixing the lower surface 32 to the shelf 10a with an adhesive. However, the present invention is not limited to this, and the installation of the airbag 30 may be performed by fixing the lower surface 32 and the shelf 10a with Velcro (registered trademark), and fixing the airbag 30 with the bottom end surface of the airbag 30 interposed therebetween. May be performed.

FIG. 9A is a diagram showing a configuration in the case where the bottom end surface of the airbag 30 is sandwiched and fixed. In this case, the lower surface 32 of the airbag 30 is longer than the upper surface 33 of the airbag 30 in the X-axis direction. The end surfaces on the X axis positive side and the X axis negative side of the lower surface 32 are pressed from above by a fastening member 211 whose length in the Y axis direction is substantially the same as that of the airbag 30, and the fastening member 211 is secured by a plurality of screws 212. It is fixed on the shelf 10a.

In the above embodiment, the positive pressure source 70 a is driven for a predetermined time, so that the upper surface 33 of the airbag 30 is in contact with the lower surface of the support sheet 110. However, the present invention is not limited to this, and the state where the upper surface 33 is in contact with the lower surface of the support sheet 110 is detected by a contact sensor 220 installed on the upper surface 33 of the airbag 30 as shown in FIG. Also good. In this case, as shown in FIG. 9B, the driving of the positive pressure source 70a is started from the state where the airbag 30 is stagnated, and the upper surface 33 comes into contact with the lower surface of the support sheet 110 by the contact sensor 220. When detected, the valve 72 is sealed, and the driving of the positive pressure source 70a is stopped. In addition, in this structure, the structure which connects the contact sensor 220 distribute | arranged in the water tank 10 to the interface 53 (refer FIG. 4) by wire or radio | wireless is provided.

In the above embodiment, the airbag 30 is switched between the maximum state and the minimum state by driving the positive pressure source 70a and the negative pressure source 70b for a predetermined time. However, the present invention is not limited to this, and how much air is filled in the airbag 30 is detected by a pressure sensor 230 provided between the valve 72 and the tube 31 as shown in FIG. You may make it do. In this case, when air is sent into the airbag 30 and the pressure sensor 230 detects that the pressure inside the airbag 30 is equal to or higher than a predetermined value, the valve 72 is sealed and positive pressure is applied. The driving of the source 70a is stopped. When the air is extracted from the inside of the airbag 30 and the pressure sensor 230 detects that the pressure inside the airbag 30 is equal to or lower than a predetermined value, the valve 72 is sealed, and the negative pressure source The driving of 70b is stopped.

In the above embodiment, the upper surface 33 of the airbag 30 supports the lower surface of the support sheet 110. However, the present invention is not limited to this, and another member may be provided between the upper surface 33 and the support sheet 110. good. The other members in this case are preferably made of a material harder than the upper surface 33 when the airbag 30 is in the maximum state.

FIG. 10A is a diagram showing a configuration in the case where the plate member 240 is provided between the upper surface 33 and the support sheet 110.

A plate member 240 that rotates about an axis 241 extending in the Y-axis direction is installed above the airbag 30. One end of the string 250 is fixed to the lower surface 242 of the plate member 240, and the other end of the string 250 is fixed to the upper surface 33 of the airbag 30. As shown in FIG. 10A, when the airbag 30 is in the minimum state, the plate member 240 is pulled downward by the string 250, and the upper surface 243 of the plate member 240 is separated from the support sheet 110.

When air is sent into the airbag 30 from the state shown in FIG. 10A, the lower surface 242 of the plate member 240 is pushed upward by the upper surface 33 of the airbag 30, and as shown in FIG. 10B. In addition, the upper surface 243 of the plate member 240 is in contact with the support sheet 110. In this state, when the valve 72 is sealed, the burden on the user when lying on the support sheet 110 can be reduced as in the above embodiment.

In this case, the support sheet 110 can be supported more stably than in the case where the support sheet 110 is directly supported by the airbag 30 as in the above embodiment. That is, although the upper surface 33 of the airbag 30 is hardened to some extent by being filled with air, if the user's weight is applied to a part of the upper surface 33 (sitting portion) when seated, this portion may be slightly recessed. . On the other hand, when the hard plate member 240 is interposed between the upper surface 33 and the support sheet 110 as in this modified example, the seating portion of the plate member 240 is unlikely to be partially recessed. A user can be supported stably. Therefore, the burden on the user when sitting can be more effectively reduced.

In addition, in FIG. 10 (a), (b), although the board member 240 and the upper surface 33 of the airbag 30 were connected with the string 250, it may connect not only with this but with the adhesive agent. Further, the plate member 240 is rotated about the shaft 241 by the airbag 30, but the present invention is not limited to this, and the plate member 240 may be rotated by a motor or the like.

Further, in the above embodiment, by using the negative pressure source 70b, the air inside the airbag 30 is extracted, and the state in which the upper surface 33 of the airbag 30 is in contact with the lower surface of the support sheet 110 is separated. And migrated. However, the present invention is not limited to this, and the airbag 30 may be provided with a contracting means such as a spring so that the airbag 30 can autonomously crawl.

FIG. 11A is a schematic diagram when the airbag 30 in this case is viewed in the positive direction of the X-axis.

A plate member 260 that covers the upper surface 33 is provided on the upper surface 33 of the airbag 30. The upper end of the spring 270 is fixed to the lower surface of the Y-axis positive side and the Y-axis negative side end of the plate member 260, and the lower end of the spring 270 is fixed to the shelf 10a. In a state in which no air is contained in the airbag 30, the upper surface 261 of the plate member 260 is separated from the lower surface of the support sheet 110 by the contraction force of the spring 270 as shown in FIG. In this case, the tube 31 is provided near the center of the lower surface 32 of the airbag 30, and the hole 11 is also provided near the center of the shelf 10a.

When air is sent into the airbag 30 from the state shown in FIG. 11A, the airbag 30 inflates against the contraction force of the spring 270, and as shown in FIG. The upper surface 261 of 260 is in contact with the lower surface of the support sheet 110. In this state, when the valve 72 is sealed, the burden on the user when lying on the support sheet 110 can be reduced as in the above embodiment. Further, when the valve 72 is opened in the state of FIG. 11B, the upper surface of the plate member 260 is separated from the lower surface of the support sheet 110 due to the contraction force of the spring 270. For this reason, according to the structure of Fig.11 (a), (b), the negative pressure source 70b is omissible.

In addition, the spring 270 shown to FIG. 11 (a), (b) may be installed in the inside of the airbag 30, as shown to FIG.11 (c), (d). In this case, the plate member 260 is omitted, and the upper surface 33 of the airbag 30 is supported by the contraction force of the spring 270 as shown in FIG. The state is separated from the lower surface of 110. Also in this case, when air is sent into the airbag 30 from the state shown in FIG. 11C, the airbag 30 inflates against the contraction force of the spring 270, and as shown in FIG. The upper surface 33 of the airbag 30 contacts the lower surface of the support sheet 110.

Moreover, in the said embodiment, although the area | region where the upper surface 33 of the airbag 30 supports the lower surface of the support sheet 110 was a part of the peripheral part of the support sheet 110, it is not restricted to this but a user seats. Depending on the position, the installation position of the airbag 30 and the width of the airbag 30 in the Y-axis direction may be set as appropriate. Further, the region in which the upper surface 33 of the airbag 30 supports the lower surface of the support sheet 110 is not limited to the peripheral portion of the support sheet 110, and the support sheet is provided as long as the driving of the injection unit 90 and the water flow generated by the injection unit 90 are not hindered. It may be extended to near the center of 110.

In the above embodiment, the pump 70 is configured to include the positive pressure source 70a and the negative pressure source 70b. However, the configuration is not limited thereto, and the pump 70 may be configured to include only the positive pressure source 70a. In this case, when the valve 72 is opened when the air is extracted from the inside of the airbag 30, the airbag 30 is unlikely to be in the minimum state, but a predetermined amount of air is released from the inside of the airbag 30, Similar to the above embodiment, the upper surface 33 of the airbag 30 is separated from the lower surface of the support sheet 110.

In the above embodiment, after the positive pressure source 70a is driven for a predetermined time, the valve 72 is sealed to trap the air inside the airbag 30, but the valve 72 is not used. In addition, the air inside the airbag 30 may be trapped. For example, the air inside the airbag 30 may be confined by continuing to drive the positive pressure source 70a while the user gets on and off. Further, a check valve may be provided between the tube 31 and the vent hole 71 of the pump 70 to confine air inside the airbag 30. In this case, a valve may be provided between the tube 31 and the check valve, and the air inside the airbag 30 may be extracted by opening the valve.

In the above embodiment, the lower surface of the support sheet 110 is supported by the upper surface 33 of the airbag 30, and the upper surface 33 moves up and down as air is taken in and out of the interior of the airbag 30. However, the present invention is not limited thereto, and the member that supports the lower surface of the support sheet 110 and the means for moving the member up and down may be performed by other mechanisms. For example, in FIGS. 10A and 10B, instead of the airbag 30 and the string 250, a mechanism for rotating the plate member 240 around the shaft 241 and maintaining the plate member 240 in a horizontal state is provided. May be. In FIGS. 11A and 11B, a mechanism for moving the plate member 260 up and down, such as a jack mechanism, may be provided instead of the airbag 30 and the spring 270.

In the above embodiment, the airbag 30 is set to the maximum state in response to the replacement instruction input by the operator after the massage is finished. However, when the massage is finished, the airbag 30 is automatically set. May be in the maximum state. For example, the airbag 30 may be automatically set to the maximum state after a predetermined time has elapsed since the end of the massage.

In the above embodiment, the gas stored in the airbag 30 is air, but other gases may be used. When other gas is used, a space for storing the gas is provided in the pump 70, and the pump 70 is configured to send the stored gas into the airbag 30. Moreover, in the said embodiment, although the liquid filled in the water tank 10 was water, another liquid may be sufficient.

Moreover, in the said embodiment, if the airbag 30 changes to the inflated state as shown in FIG.7 (b), the pressure in the water tank 10 will be raised and the support sheet 110 which is not supported by the airbag 30 will be shown. The part of became difficult to bend. Thus, when the airbag 30 is inflated to increase the pressure in the water tank 10, the burden on the user when lying on the support sheet 110 and getting off the water bed 1 can be effectively reduced. Hereinafter, a modified example of the embodiment focusing on this will be described.

The configuration of this modification will be described with reference to FIGS. 12 (a) and 12 (b) and FIGS. 13 (a) and 13 (b). 12 (a), 12 (b) and FIGS. 13 (a), 13 (b), the X axis in FIGS. 1 (a), 1 (b), 2 (a), 2 (b) of the above embodiment. The Y axis is rotated by 180 degrees with the Z axis as the central axis. Further, in the description of the configuration described below, only the points where the present modified example is modified from the above embodiment will be described.

As shown in FIG. 12 (a), in this modified example, a bottom 10c parallel to the XY plane is provided at a position deeper than the shelf 10a of the water tank 10. The bottom 10c is located on the Y axis negative side of the shelf 10a on the X axis negative side, and is located on the same plane as the bottom 10b. In the present modification, the hole 11 is provided in the bottom 10c. As shown in FIGS. 12A and 12B, in this modification, the length of the airbag 30 in the Y-axis direction is shorter than that in the above embodiment, and the tube 31 is formed of the airbag 30. Is connected to the lower surface 32.

Also in this modified example, the assembly is performed in the same manner as in the above embodiment. At this time, the lower surface 32 of the airbag 32 is fixed to the bottom surface 10c with an adhesive. Moreover, in this modification, the partition member 17 is installed between the bottom 10b and the bottom 10c. Thus, after assembling as shown in FIGS. 13 (a) and 13 (b), each part is further installed in the same manner as in the above embodiment, and as shown in FIG. 3 (b), substantially the same as in the above embodiment. The water bed 1 having the appearance is completed.

Next, the operation of this modification will be described with reference to FIGS. 14 (a) to 14 (c) and FIGS. 15 (a) and 15 (b).

Immediately after the power is turned on and during massage, the airbag 30 is in a minimum state as shown in FIG. At the time of sitting, air is sent into the airbag 30 from this state, and the airbag 30 is brought to a maximum state as shown in FIG. As a result, water in a space closed by the water tank 10 and the support sheet 110 (hereinafter referred to as “sealed space”) tends to spread from the upper surface of the water tank 10 to the outside. Therefore, the pressure in the sealed space is increased. For this reason, the pressure concerning the support sheet 110 is raised. In this state, even if a user who wants to perform massage sits on the support sheet 110 as shown in FIG. 14C, the support sheet 110 is difficult to bend. Therefore, since the user can sit on the support sheet 110 smoothly, the burden when the user lies on the support sheet 110 can be effectively reduced.

Also, when the massage is finished and the user gets off the water bed 1, the air is sent into the airbag 30 and the airbag 30 is brought to the maximum state. Thereby, the pressure in sealed space is raised and the pressure concerning the support sheet 110 is raised. Therefore, the user lying on the support sheet 110 can smoothly sit on the support sheet 110 and get off the water bed 1.

Further, the pressure in the sealed space can be changed by taking air into and out of the airbag 30. Thereby, the pressure in sealed space can be changed with a simple structure, without using a complicated mechanism.

Further, during the massage, as shown in FIG. 12 (a), the airbag 30 is in a minimum state. Thereby, since the pressure in sealed space becomes low, the pressure concerning the support sheet 110 becomes low. Thereby, the support sheet 110 becomes easy to bend and a comfortable massage effect can be provided to the user.

Immediately after the user lies on the support sheet 110, the airbag 30 is in the maximum state as shown in FIG. During massage, air is extracted from the inside of the airbag 30 from this state, and the airbag 30 is brought to a minimum state as shown in FIG. Thereby, since the pressure in sealed space becomes low, the support sheet 110 becomes easy to bend. Therefore, it becomes easy for the user to be buried in the support sheet 110, and the massage effect for the user can be enhanced.

In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
