Abstract

PROBLEM TO BE SOLVED: To automatically adjust the height of a pillow in accordance with the posture of a human body lying on a bed. SOLUTION: The pillow 1 is connected to a pump means 2 by a tube 5. A pressure sensor unit 7 is connected to a mat 6 arranged just under the upper half of the human body with the tube 8. The pressure sensor unit 7 is connected to the motor 4 of the pump means 2. When the human body is lying on its back, the mat 6 receives the pressure of a base area from the upper half body. At the time of lying on its side, pressure is received in a narrow area. Then, the pressure is detected by the pressure sensor '7 so that the injection amount of a fluid from the pump means 2 to the pillow 1 is reduced at the time of lying on the back so as to make the pillow low and the injection amount of the fluid is increased at the time of lying on the side so as to highten the pillow. Therefore, the height of the pillow is automatically adjusted in accordance with the posture of the human body lying on the bed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mache device which can automatically adjust the height of a mache according to the posture of a human body lying on bedding.

[0002]

2. Description of the Related Art Conventionally, macula used at bedtime has been
Various things have been proposed. A human body lying on bedding such as a bed or a futon changes its posture by unconsciously turning over. Is desirably high.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a machera device which can automatically adjust the height of a mache according to the posture of a human body lying on bedding.

[0004]

According to the present invention, there is provided a macula apparatus comprising:
A macula capable of injecting fluid, an elastically deformable mat laid under the upper body of a human body lying on the bedding and injecting fluid, a pressure sensor unit for detecting the pressure received by the mat from the human body, Pump means for injecting and discharging a fluid to and from the macula according to an output signal of the sensor unit.

[0005]

According to the present invention having the above construction, the height of the macula can be automatically adjusted by detecting the pressure applied to the mat from the human body by the pressure sensor unit and driving the pump means according to the detection result. it can.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a plan view of the muffler device, FIG. 2 is a cross-sectional view of the pump means, FIG. 3 is a cross-sectional view of the pressure sensor unit, and FIGS. 4 and 5 are side views when the muffler device is used.

First, the overall configuration of the macula apparatus will be described with reference to FIG. The macula 1 is made of a material such as a rubber bag or a plastic bag into which liquid can be poured. Reference numeral 2 denotes a pump means, which comprises a piston portion 3 and a motor 4. The piston portion 3 and the muffler 1 are connected by a tube 5.
As described later, the pump means 2 injects a liquid into the muffler 1 and discharges a fluid from the muffler 1.

Reference numeral 6 denotes a mat. The mat 6 is laid directly under the upper body of a human body lying on bedding such as a bed or a futon. The mat 6 is an elastically deformable air mat or the like, into which a fluid such as air is injected. Reference numeral 7 denotes a pressure sensor unit, which is connected to the mat 6 by a tube 8 and detects the magnitude of the pressure applied to the mat 6 from a human body. The pressure sensor unit 7 and the motor 4 are connected by a cord 9 via a control unit 10.

Next, the pump means 2 will be described with reference to FIG. The piston portion 3 includes a cylindrical main body 11, a side plate 13 detachably mounted on both side surfaces of the main body 11 with screw portions 12, and a feed screw 14 which is driven by the motor 4 and rotates.
, A nut 15 screwed to the feed screw 14 and a nut 1
5 comprises a tongue piece 16 elastically contacting the inner surface of the main body 11. 17 is a bearing part. The fluid 18 is stored inside the main body 11.

When the motor 4 is driven forward and the feed screw 14 is rotated forward, the nut 15 moves rightward in FIG. 2 along the feed screw 14, whereby the fluid 18 in the main body 11 is moved.
Is pumped through the tube 5 to the muffler 1, which expands. When the motor 4 is reversely driven and the feed screw 14 is rotated in the reverse direction, the nut 15 moves to the left, the fluid 18 in the muffler 1 is returned to the main body 11, and the muffler 1 collapses.

Next, the pressure sensor unit 7 will be described with reference to FIG. Tube 8 extending from macula 1
An elastic bag 20 such as a balloon is attached to the tip of the. Reference numeral 21 denotes a micro switch, and its lever 22
Extend to the elastic bag 20 side. Micro switch 21
Is mounted on an elastic plate 23 such as a leaf spring. The elastic plate 23 is supported by a cylindrical support 24. Support 2
A cover body 25 is screwed to 4 by a screw portion 26. The cover body 25 has a projection 27 protruding toward the elastic plate 23.

When the liquid pumped from the muffler 1 enters the elastic bag 20, the elastic bag 20 expands (see the elastic bag 20 shown by a dashed line) and presses the lever 22. Then, the micro switch 21 is turned on, the signal is sent to the control unit 10 through the code 9 (FIG. 1), and the motor 4 is driven.

This muffler device has the above-described configuration, and the operation will be described next. FIG. 4 shows a state of lying on the bedding 30 facing up (see also FIG. 1), the head is placed on the macula 1, and the mat 6 is laid directly under the upper body. When you are lying on your back like this,
It is desirable that the height h of the macula 1 is low. As shown in FIG. 5, it is desirable that the height H of the macula 1 is higher when the player turns over and changes his or her posture to the side.

By the way, as shown in FIGS. 1 and 4,
When lying on the back, the mat 6 receives a large area pressure from the upper body, so that the elastic bag 2 shown in FIG.
At 0, a large amount of fluid is sent from the mache 1 and swells greatly, and the lever 22 of the limit switch 21 is turned on. On the other hand, when laying sideways as shown in FIG. 5, since the mat 6 receives only a relatively small area of pressure from the upper body, the elastic bag 20 does not expand significantly, so that the lever 22 of the limit switch 21 is not turned on.

As described above, the pressure which the mat 1 receives from the human body varies depending on the posture of the human body, and this is detected by the pressure sensor unit 7 having the elastic bag 20. The motor 4 is driven by the detection signal. When the motor 4 is lying on its side as shown in FIG.
And the height h of the macula 1 is reduced. Also, when lying down as shown in FIG. 5,
The height H of the macula 1 is increased by increasing the injection amount of the fluid 18 into the macula 1. Thus, according to this macula device,
The height of the muffler 1 can be automatically adjusted according to the posture of the human body lying on the bedding 30.

The sensitivity to the pressure sensor unit 7 can be adjusted by rotating the cover 25. That is, in FIG.
Of the micro switch 21 to the elastic bag 20.
, The sensitivity of the microswitch 21 increases, and the expansion of the elastic bag 20 can be detected earlier. Therefore, the user can change the distance between the microswitch 21 and the elastic bag 20 according to his / her preference.

The present invention is not limited to the above embodiment. For example, pump means and pressure sensors
Various things can be applied.

[0018]

As described above, according to the present invention, the pressure received from the human body by the mat is detected by the pressure sensor unit, and the pump means is driven in accordance with the detected result, thereby automatically adjusting the height of the macula. It can adjust comfortably and can realize comfortable sleep.
