BEST MODE FOR CARRYING OUT THE INVENTION

[0014] Examples of the present invention will be described below.

Example

[0015] An embodiment of the present invention will be described with reference to the drawings. First, FIG. 1 is a perspective view showing an entire image of a sofa 1 as an embodiment of furniture having an illumination function according to the present invention. Yes. The sofa 1 is composed of eight flexible balloons 2a to 2h formed of a translucent translucent polyurethane resin material that is formed as a bag body that can seal a gas (air) inside. The main body is composed of a cushion body 2 and a base 4 arranged below the cushion body 2.

[0016] As shown in Figs. 1 and 2, the cushion body 2 in the present embodiment includes eight norens 2a to 2h that are independently formed in a horizontally long substantially rectangular parallelepiped shape on the base 4. Each balloon is arranged so that the height gradually decreases toward the left and right sides of the central force in FIG. Each of these balloons 2a to 2h is fitted in an annular tube 6 made of a transparent acrylic resin material fixed on the upper surface of the base 4 and arranged so as not to be displaced. A seat for the user is formed on the upper surface of the balloons 2a to 2h.

[0017] The base 4 has a cylindrical shape with a hollow interior, and inside the base 4, as shown in the schematic structural diagram of FIG. 3, the air chambers R of the balloons 2a to 2h, respectively. And a plurality of LED modules 3a to 3h composed of a plurality of LEDs 3 as irradiation means for irradiating the air chamber R of the corresponding balloon upward with downward force, and each balloon 2a to 2h. When there is a change in the air pressure sensor 5 which is arranged corresponding to each air chamber R and detects the pressure in the corresponding air chamber R, and the pressure detected by the air pressure sensor 5 And a control board 11 provided with a control unit 10 as an irradiation control means for performing control to change the light quantity of the LED 3 of the LED module (3a to 3h) corresponding to the air chamber R in which the pressure has changed. It has been.

[0018] The LED modules 3a to 3h and the air pressure sensor 5 are provided in the base 4 as shown in FIG. LED3 in LED module 3a-3h is placed upward so that it can be irradiated from the inside of base 4 toward the upper balloon (2a-2h). Has been. The upper surface of the base 4 is made of a transparent plate (for example, a transparent synthetic resin plate or a glass plate) (not shown). The lanes 2a to 2h arranged in Fig. 1 are irradiated. By irradiating the irradiation light of this LED3 force to the balloons 2a to 2h, the lanes 2a to 2h themselves emit light by the irregular reflection action by the translucent polyurethane resin constituting the balloons 2a to 2h. Will look like.

[0019] The air chamber R corresponding to the detection part of each air pressure sensor 5 is communicated via a communication pipe (not shown), and the gas flowing out from the air chamber R via the communication pipe is inside the air chamber R. Air pressure is detected. In the present embodiment, air (gas) is injected into the air chamber R, but liquid may be injected.

Next, the configuration of the sofa 1 of the present embodiment will be described based on the block diagram shown in FIG. 4. The sofa 1 of the present embodiment includes a plurality of balloons 2 a to 2 that constitute the cushion body 2. 2h, air module 5 in the air chamber 2 of the lane 2, air pressure sensor 5 for detecting the air pressure in the interior R, LED modules 3a to 3h consisting of a plurality of LEDs 3 that irradiate the corresponding balloon 2 from below, and LED modules 3a to 3h The air pressure sensor 5 is connected via an IZO module, and a control board 11 provided with a control unit 10 for controlling each of these units.

Next, the operation of the sofa 1 as the present embodiment will be described with reference to FIG.

[0022] When it is detected that one of the balloons 2a to 2h has been compressed and the air pressure inside the air chamber R has risen to a predetermined reference value, the control unit 10 has reached the predetermined reference value. The LED modules 3a to 3h corresponding to the balloons 2a to 2h are turned on with a predetermined light color (blue in this example), and if the air pressure further increases, the light quantity of the LED 3 is adjusted according to the increase of the air pressure. If the air pressure increases and the air pressure decreases, the light amount of the LED 3 is reduced according to the air pressure reduction. When the air pressure falls below the predetermined reference value, the LED 3 is turned off.

In the present embodiment, the control unit 10 lights the LED 3 with a predetermined light amount corresponding to the pressure range detected by each air pressure sensor 5. As the pressure increases and decreases, the light intensity of LED3 increases or decreases step by step.

Specifically, as shown in FIG. 5, for example, a user sits on the seat on the upper surface of the cushion body 2 so that the vicinity of the center position of the upper surface seat on the cushion body 2 faces downward. When pressed, the LED modules 3d and 3e corresponding to the balloons 2d and 2e near the pressed center are lit with a light intensity corresponding to the pressure detected by the corresponding air pressure sensor 5.

[0025] Here, the balloons 2c and 2f arranged adjacent to the central balloons 2d and 2e are not directly applied with an external force, but are deformed so that the adjacent balloons 2d and 2e expand in the lateral direction. As a result, the air pressure of the air chamber R of the balloons 2c and 2f also rises, so the LED modules 3c and 3f of the corresponding LED modules 3c and 3f also correspond to the pressure detected by the corresponding air pressure sensor 5. Lights up with light intensity.

[0026] Furthermore, the balloons 2b and 2g adjacent to the balloons 2c and 2f are also pressed by the balloons 2c and 2f deformed so as to expand in the lateral direction, so that the LED modules 3b and 3g corresponding to them are Lights up with the light intensity corresponding to the pressure detected by the corresponding air pressure sensor 5.

[0027] In FIG. 5, the higher the density of the diagonal lines, the higher the light intensity of the LED3, and the external force is applied only near the center as indicated by the arrows in the figure. When the power is applied, the area around the center where the force is directly applied becomes brightest, and gradually fades toward the surroundings.

[0028] Thus, in the sofa 1 in this embodiment, when the cushion body 2 is partially pressed, for example, when a person sits on the cushion body 2 or lies down, the pressure is reduced. The irradiation control of the LEDs 3 of the LED modules 3a to 3h corresponding to the air chambers R of the balloons 2a to 2h where the pressure changes has occurred. That is, the irradiation light quantity of the cushion body 2 partially changes (increases or decreases) following the use position of the user, so that not only the vicinity of the user always becomes bright, but also according to the use situation of the user. As a result, the decoration effect in the room increases.

[0029] Further, the control unit 10 in the present embodiment controls the amount of light of the LED 3 for a period (speed) until the air pressure of the predetermined air chamber R rises or falls to the second value. The above Light intensity corresponding to the first value of air pressure Control is performed to slow down the period (speed) of increasing or decreasing to the light intensity corresponding to the second value of air pressure. Specifically, for example, if it takes 500 ms for the air pressure in a predetermined air chamber R to rise to the first value force and the second value, the light quantity of LED3 corresponds to the first value of the air pressure. The time for increasing the light amount to the light amount corresponding to the second value of the air pressure is, for example, 1 second. As a result, the change in light becomes duller than the change in air pressure, and the reaction of light becomes soft. Therefore, the cushioning property of the cushion body 2 made of air can be visually expressed by the effect of light.

[0030] Furthermore, the direction (speed) of changing the amount of light of LED3 when the air pressure in air chamber R rises is higher than when the air pressure falls. Specifically, for example, if it takes 500 ms for the air pressure of a predetermined air chamber scale to rise to the second value, the light intensity of LED 3 corresponds to the first value of the air pressure. Light intensity The time to increase the light intensity corresponding to the second value of the air pressure is 1 second, while the air pressure in the predetermined air chamber R is the second value force 500 ms to decrease to the first value Is required to reduce the light intensity of the LED 3 to the light intensity corresponding to the second value of the air pressure to 1.5 seconds as the light intensity corresponding to the first value of the air pressure. This makes it possible to slow down changes in light without causing stress.

[0031] Note that the irradiation control of the LED 3 by the control unit 10 in the present embodiment is a light amount control (dimming), but, for example, contrary to the embodiment, when the air pressure in the air chamber R increases, It is possible to reduce the amount of light and increase the amount of light in LED3 by lowering the air pressure in air chamber R.

[0032] In addition, the LED3 irradiation control by the control unit 10 is not limited to light amount control (dimming). For example, according to a change in air pressure of the air chamber R, illumination of colored light, lighting, blinking, etc. You may make it perform control of a projection mode. Specifically, control is performed so that all LEDs 3 are lit at normal time, and the irradiation light color of the LED 3 corresponding to the air chamber R in which the air pressure has changed, for example, the gradation of the blue force is changed to red or the like. You may do it.

[0033] In addition, the LED 3 as the irradiation means in the present embodiment is provided in the base 4 that is separable from the cushion main body 2 disposed below the cushion main body 2. Since there is no need to install LED3 etc. inside, not only will it be easier to manufacture, In other words, maintenance and the like can be easily performed.

[0034] In this embodiment, the LED 3 as the irradiation means is disposed below the cushion body 2. The present invention is not limited to this. For example, the LED 3 is the air chamber R of the cushion body 2. You may arrange | position inside. Further, although an LED is applied as an example of the irradiation means, a lamp or the like may be applied.

As described above, the embodiments of the present invention have been described with reference to the drawings. However, the specific configuration is not limited to these embodiments, and there is any change or additional effort within the scope of the present invention. It is included in the present invention.

[0036] For example, in the above embodiment, the force applied to the sofa 1 as an example of furniture is not limited to this. The present invention may be applied to a chair or a bed. Further, the shape of the sofa 1 is not limited to the shape described in the above embodiment.

[0037] Further, the cushion main body 2 in the above embodiment has a force inner chamber R that is configured by a plurality of balloons 2a to 2h that are independently formed. You can configure it with a bano lane.

[0038] Further, in the sofa 1 in the above embodiment, the force that one control unit 10 performs the irradiation control of all the LEDs 3 corresponding to the plurality of balloons 2a to 2h, for example, each balloon 2a to Control units that control LED3 and air pressure sensor 5 corresponding to 2h are electrically connected to each other, and control information is exchanged between the control units to control irradiation of each LED module. Anyway.
