As a type of chair, an air-conditioned chair is known that is equipped with an air outlet that blows out conditioned air supplied from an underfloor space to a seated person (for example, see Patent Document 1). Further, the air outlet provided in the air-conditioned chair described in Patent Document 1 is configured to be opened and closed manually.

Patent No. 5444574

In such air-conditioned chairs, in order to ensure comfort by blowing out conditioned air to the seated occupants, and to reduce wasteful consumption of conditioned air and improve energy savings, it is necessary to set the air outlet appropriately. It needs to open and close at the right time. However, in the air-conditioned chair described in Patent Document 1, the air outlet is manually opened and closed, so opening and closing it frequently requires a great deal of effort, and the air outlet is not opened and closed at an effective time. It was very difficult to open and close it.
In view of this situation, the main object of the present invention is to provide a technology that can improve energy saving while ensuring the comfort of a seated person in a so-called flip-up air-conditioned chair.

A first feature of the present invention is that the seat part is supported so as to be freely changeable between a sitting position extending forward from the lower end side of the backrest part and a retracted position retracting backward from the sitting position, and the seat part is supported under the floor. An air-conditioned chair equipped with an outlet that blows out conditioned air supplied from a space to a seated person,

The air outlet opening/closing mechanism opens and closes the foot air outlet and the backrest air outlet at the same time.

According to this configuration, in a so-called flip-up type air-conditioned chair, by providing the above-mentioned air outlet opening/closing mechanism, the air outlet that blows out the conditioned air supplied from the underfloor space to the seated person can be opened without any effort. The air outlet can be opened and closed at appropriate timing.
That is, when a seated person is seated and the posture of the seat is changed to a seated position, the air outlet is automatically opened by the air outlet opening/closing mechanism to ensure that the airflow from the air outlet is provided to the seated person. Since the conditioned air is blown out, the comfort of the seated occupants can be appropriately ensured without any effort.
On the other hand, when the seated person leaves the seat and the seat position changes to the retracted position, the air outlet opening/closing mechanism automatically closes the air outlet and wastes the conditioned air from the air outlet. Since the blowing is stopped, energy saving can be appropriately improved without any effort.
Therefore, according to the present invention, it is possible to provide a so-called flip-up air-conditioned chair that can improve energy saving while ensuring the comfort of the seated person.
Furthermore, according to this configuration, when a seated person is seated and the posture of the seat is changed to the seated posture, the conditioned air taken into the air intake section is transferred to the foot outlet and the backrest outlet. Conditioned air can be blown out to the seated person from both the foot air outlet and the backrest air outlet, thereby further improving the comfort of the seated person.
Furthermore, since the foot air outlet and the backrest air outlet are both formed in the same air intake part, the air outlet opening/closing mechanism has a relatively simple configuration to connect the foot air outlet and the backrest air outlet. can be configured to open and close at the same time.

A second feature of the present invention is that the seat part is supported so as to be freely changeable between a sitting position extending forward from the lower end side of the backrest part and a retracted position retracting backward from the sitting position, and the seat part is supported under the floor. An air-conditioned chair equipped with an outlet that blows out conditioned air supplied from a space to a seated person,

According to this configuration, in a so-called flip-up type air-conditioned chair, by providing the above-mentioned air outlet opening/closing mechanism, the air outlet that blows out the conditioned air supplied from the underfloor space to the seated person can be opened without any effort. The air outlet can be opened and closed at appropriate timing.
That is, when a seated person is seated and the posture of the seat is changed to a seated position, the air outlet is automatically opened by the air outlet opening/closing mechanism to ensure that the airflow from the air outlet is provided to the seated person. Since the conditioned air is blown out, the comfort of the seated occupants can be appropriately ensured without any effort.
On the other hand, when the seated person leaves the seat and the seat position changes to the retracted position, the air outlet opening/closing mechanism automatically closes the air outlet and wastes the conditioned air from the air outlet. Since the blowing is stopped, energy saving can be appropriately improved without any effort.
Therefore, according to the present invention, it is possible to provide a so-called flip-up air-conditioned chair that can improve energy saving while ensuring the comfort of the seated person.
Further, according to this configuration, when a seated person turns the seat while seated and changes the posture to a seated position, the conditioned air taken into the air intake section is transferred from the footwell outlet to the seat. Air can be blown forward along the bottom surface of the seat to improve comfort at the feet of the seated person.
Furthermore, when such a foot air outlet is provided, the air outlet opening/closing mechanism part is configured to move the rocking plate backward from the foot air outlet to open the foot air outlet when the seat is in the sitting position. , when the seat is in the retracted position, a swing plate is brought into contact with the periphery of the foot outlet from the rear to close the foot outlet. It is possible to realize a configuration in which the foot air outlet is opened and closed in conjunction with the change.

A third feature of the present invention is that the seat part is supported so as to be freely changeable between a sitting position extending forward from the lower end side of the backrest part and a retracted position retracting backward from the sitting position, and the seat part is supported under the floor. An air-conditioned chair equipped with an outlet that blows out conditioned air supplied from a space to a seated person,

According to this configuration, in a so-called flip-up type air-conditioned chair, by providing the above-mentioned air outlet opening/closing mechanism, the air outlet that blows out the conditioned air supplied from the underfloor space to the seated person can be opened without any effort. The air outlet can be opened and closed at appropriate timing.
That is, when a seated person is seated and the posture of the seat is changed to a seated position, the air outlet is automatically opened by the air outlet opening/closing mechanism to ensure that the airflow from the air outlet is provided to the seated person. Since the conditioned air is blown out, the comfort of the seated occupants can be appropriately ensured without any effort.
On the other hand, when the seated person leaves the seat and the seat position changes to the retracted position, the air outlet opening/closing mechanism automatically closes the air outlet and wastes the conditioned air from the air outlet. Since the blowing is stopped, energy saving can be appropriately improved without any effort.
Therefore, according to the present invention, it is possible to provide a so-called flip-up air-conditioned chair that can improve energy saving while ensuring the comfort of the seated person.
Furthermore, according to this configuration, when a seated person turns the seat part to change the posture to a seated position while seated, the conditioned air taken into the air intake part is discharged from the backrest part outlet to the seat.

Embodiments of the present invention will be described based on the drawings.
As shown in FIGS. 1 to 3, the air-conditioned chair 1 according to the present embodiment is mainly used as a plurality of audience seats in a theater, with the backrest 2 facing the legs 4 erected on the floor 60. It has a structure in which the seat portion 3 is supported. In the present application, with the backrest 2 as a reference, the side on which the seat 3 on which a seated person sits is arranged will be referred to as the front side, and the opposite side will be referred to as the rear side.

The seat portion 3 is supported so as to be able to rotate around a substantially horizontal rotation axis 3b along the edge of the rear end portion 3a, and to change its posture between a sitting posture and a retracted posture.
The sitting posture of the seat portion 3 is a posture extending forward from the lower end portion 2a side of the backrest portion 2, as in the air-conditioned chair 1 shown on the left side of FIG. 1 and in FIG. On the other hand, the retracted position of the seat part 3 is rotated around the rotation axis 3b on the rear end part 3a side with respect to the sitting position, as in the air-conditioned chair 1 shown in the right side of FIG. 1 and in FIG. This is a posture in which the person flips up upwards and retreats to the rear of the seated posture.
Further, the rotating shaft 3b of the seat portion 3 is provided with an urging means 45 that urges the seat portion 3 to change its posture from the seating position to the retracted position. Note that as this biasing means 45, a known mechanism such as a torsion spring that applies a repulsive force to the shaft on the seat portion 3 side so as to rotate from the sitting position side to the retracted position side may be adopted, for example. can.
Then, the seated person can manually change the posture of the seat 3 from the retracted posture to the sitting posture against the biasing force of the biasing means 45 and sit on the seat 3 in the sitting posture; When the seated person leaves the seat, the biasing means 45 automatically changes the posture of the seat portion 3 from the sitting posture to the retracted posture.

An underfloor space 55 is formed below the floor 60 on which the air-conditioned chair 1 is installed, and conditioned air SA, which is cold or warm air, is supplied from the air conditioner 50 to the underfloor space 55.
Further, the control device 53 that controls the operation of the air conditioner 50 controls the output of the air supply fan 51 so that the internal pressure of the underfloor space 55 detected by the pressure sensor 52 is maintained at a predetermined set pressure. The amount of conditioned air SA supplied to the space 55 is adjusted.

An air intake part 5 is formed inside the leg part 4 of the air-conditioned chair 1, and is provided below the rear end part 3a of the seat part 3 to take in the conditioned air SA supplied from the underfloor space 55. There is.
The air-conditioned chair 1 has a foot outlet 11 and a backrest outlet 12 as outlets for blowing out the conditioned air SA taken into the air intake section 5 from the underfloor space 55 to the seated person on the seat section 3. It is provided.
The foot outlet 11 is configured as an outlet that opens on the front surface above the air intake part 5 in the leg part 4 and blows out the conditioned air SA from the air intake part 5 to the bottom side of the seat part 3.
On the other hand, the backrest outlet 12 opens in the gap between the rear end 3a of the seat 3 and the lower end 2a of the backrest 2 on the upper surface of the air intake 5, and It is configured as an outlet that blows out the conditioned air SA to the front side of the backrest portion 2 through the gap.
Further, below the seat 3, a protrusion 40, such as a plate-shaped protrusion, is provided that protrudes forward from the lower edge of the foot outlet 11 in order to prevent the foot outlet 11 from being blocked by luggage.

The air-conditioned chair 1 includes a foot outlet opening/closing mechanism 20 that opens and closes the foot outlet 11 in conjunction with changes in the posture of the seat 3 in order to improve energy saving while ensuring the comfort of the seated person. (an example of an air outlet opening/closing mechanism) and a backrest air outlet opening/closing mechanism 30 (an example of an air outlet opening/closing mechanism) that opens and closes the back air outlet 12 in conjunction with a change in the posture of the seat 3. ing. The detailed configuration of each of these outlet opening/closing mechanisms 20 and 30 will be explained below.

The foot outlet opening/closing mechanism 20 opens the foot outlet 11 when the seat 3 is in the sitting position (see FIG. 2), and opens the foot outlet 11 when the seat 3 is in the retracted position (see FIG. 3). It is configured as an air outlet opening/closing mechanism section that closes the air outlet 11. That is, the foot outlet opening/closing mechanism section 20 includes a fixed horizontal plate 21 and a swinging plate 22 provided inside the air intake section 5. The fixed horizontal plate 21 is configured as a plate that is located below the rotation axis 3b of the seat 3 in the sitting position, is fixed to the bottom surface of the seat 3, and extends in a substantially horizontal direction. On the other hand, the swing plate 22 is configured as a plate that is connected to the rear end of the fixed horizontal plate 21 along its edge so as to be freely swingable around a swing shaft 22a consisting of a substantially horizontal hinge or the like. has been done.

As shown in FIG. 2, when the seat 3 is in the sitting position, the fixed horizontal plate 21 is in a reclining position extending substantially horizontally along the bottom of the seat 3, and the swing axis located at the rear end The swing plate 22, which is swingably connected around the swing plate 22a, is maintained in a substantially vertically hanging position due to its own weight. At this time, the swing shaft 22a on which the swing plate 22 hangs is located behind the peripheral edge 11a of the foot outlet 11 in the front-rear direction. Then, the swing plate 22 is moved away from the foot outlet 11, and the foot outlet 11 is opened. In this way, when a seated person manually rotates the seat 3 against the biasing force of the biasing means 45 to change the posture to the sitting posture while seated, the posture of the seat 3 is changed. In conjunction with this, the footwell outlet 11 is automatically opened, and the conditioned air SA taken into the air intake section 5 is blown out from the footwell outlet 11 forward along the bottom surface of the seat 3. The comfort of the underfoot area is improved.
Further, when the foot outlet 11 is opened and the conditioned air S is blown out, the control device 53 that controls the operation of the air conditioner 50 controls the underfloor space 55 detected by the pressure sensor 52 as the conditioned air SA is blown out. In order to suppress the internal pressure from decreasing, the output of the air supply fan 51 is automatically controlled to the increasing side, so the amount of conditioned air SA supplied to the underfloor space 55 is linked to the opening of the foot outlet 11. will be automatically increased.

On the other hand, as shown in FIG. 3, when the seat 3 is in the retracted position, the fixed horizontal plate 21 is in a standing position extending substantially vertically along the seat 3, and around the swing shaft 22a located at the rear end. The swing plate 22, which is swingably connected to the swing plate 22, is maintained in a substantially vertically hanging position due to its own weight. At this time, the swing shaft 22a on which the swing plate 22 hangs is located at approximately the same position as the peripheral edge 11a of the foot outlet 11 or in front of it in the front-rear direction. Then, the swing plate 22 comes into contact with the peripheral edge 11a of the foot outlet 11 from behind, and the foot outlet 11 is closed. Further, a permanent magnet 11b can be provided on the peripheral edge 11a of the foot outlet 11 for magnetically adhering to the metal rocking plate 22 to assist the rocking plate 22 in closing the foot outlet 11. . In this way, when the seated person leaves the seat and the posture of the seat 3 is automatically changed from the seated posture to the retracted posture by the urging means 45, the position of the seat 3 is automatically changed in conjunction with the change in the posture of the seat 3. The foot outlet 11 is automatically closed, and wasteful blowing of the conditioned air SA from the foot outlet 11 is stopped.
Further, when the foot outlet 11 is closed and the blowing of the conditioned air SA is stopped, the control device 53 that controls the operation of the air conditioner 50 detects the pressure with the pressure sensor 52 as the blowing of the conditioned air SA stops. In order to suppress the increase in the internal pressure of the underfloor space 55, the output of the air supply fan 51 is automatically controlled to the decreasing side, so that the amount of conditioned air SA supplied to the underfloor space 55 is equal to It will be automatically reduced in conjunction with the closure. That is, when the wasteful blowing of conditioned air SA from the footwell outlet 11 is stopped, the amount of conditioned air SA supplied from the air conditioner 50 to the underfloor space 55 is reduced, and energy saving is improved.

The backrest outlet opening/closing mechanism 30 opens the backrest outlet 12 when the seat 3 is in the seated position (see FIG. 2), and opens the backrest outlet 12 when the seat 3 is in the retracted position (see FIG. 3). It is configured as an air outlet opening/closing mechanism that closes the partial air outlet 12. That is, the backrest outlet opening/closing mechanism section 30 includes a fixed vertical plate 31 provided inside the air intake section 5. The fixed vertical plate 31 is configured as a plate that is located behind the rotation axis 3b of the seat part 3 in the sitting position, is fixed to the fixed horizontal plate 21 fixed to the bottom surface of the seat part 3, and extends in a substantially vertical direction. ing.

As shown in FIG. 2, when the seat part 3 is in the sitting position, the fixed vertical plate 31 is in a standing position extending in a substantially vertical direction, and the fixed vertical plate 31 is placed above the backrest part air outlet 12. After separating, the backrest outlet 12 is opened. Therefore, when a seated person manually rotates the seat 3 against the biasing force of the biasing means 45 to change the posture to the seated posture while seated, the position of the seat 3 is linked with the change in the posture of the seat 3. Then, the backrest outlet 12 is automatically opened, and the conditioned air SA taken into the air intake part 5 is sent from the backrest outlet 12 to the rear end 3a of the seat 3 and the lower end 2a of the backrest 2. Since the air is blown out to the front side of the backrest portion 2 through the gap between them, the comfort of the back portion of the seated person is improved.

On the other hand, as shown in FIG. 3, when the seat part 3 is in the retracted position, the fixed vertical plate 31 is in a reclined position extending in a substantially horizontal direction, and the fixed vertical plate 31 is located at the peripheral edge of the backrest part air outlet 12. 12a from above, the backrest outlet 12 is closed. A protruding piece 32 is provided that protrudes inward from the inner wall of the air intake portion 5, and its end portion meets the peripheral edge 12a of the backrest outlet 12, which the fixed vertical plate 31 abuts from above. has been done. Therefore, when the seated person leaves the seat and the posture of the seat 3 is automatically changed from the sitting posture to the retracted posture by the urging means 45, the backrest portion The air outlet 12 is automatically closed, and wasteful blowing of the conditioned air SA from the backrest air outlet 12 is stopped. When the unnecessary blowing of conditioned air SA from the backrest outlet 12 is stopped, the amount of conditioned air SA supplied from the air conditioner 50 to the underfloor space 55 is reduced as described above, improving energy saving. be done.

As described above, this air-conditioned chair 1 adopts a configuration in which the conditioned air SA taken into the air intake section 5 is divided into the foot outlet 11 and the backrest outlet 12, so that the opening and closing of the foot outlet is controlled. The mechanism section 20 and the backrest outlet opening/closing mechanism section 30 are constructed integrally with a relatively simple structure so as to simultaneously open and close the foot outlet 11 and the backrest outlet 12.
