Next, the control mechanism of the drive machine M441 will be explained with reference to FIGS. 1 and 2.

81 is a transmitter that transmits an infrared signal, and this transmission 1
1181 has a plurality of operation buttons 81a.

Further, a receiver 82 for receiving a signal transmitted from the transmitter 81 is disposed at the lowermost portion of the front surface of the furniture main body 11. Furthermore, a control device 83 for controlling the electric motor 1fi 43 is provided, for example, on the bottom rear side of the furniture main body 11.
is provided, and the receiver 82 is connected to this control device 83.
and limit switch 77 are electrically connected.

Then, according to the signal received by the receiving 1fi82,
The electric power converter 43 is configured to be started or stopped in either forward or reverse direction.

Further, when the limit switch 77 is opened, the electric motor 43 is stopped.

Next, the operation of the furniture door device will be explained.

By operating the transmitter 81, the user can
can be opened and closed. That is, when an appropriate operation button 81a of the transmitter 81 is pressed and an infrared signal is transmitted from the transmitter 1fi81 to the receiver ll182, the control device 83 turns on and off the electric motor 43 according to the signal received by the receiver 82. control, and the door body 13 opens and closes.

As shown in FIG. 1 etc., when the output shaft of the electric motor 43 is rotated in one direction (the positive direction) with the door body 13 blocking the front opening 12 of the furniture body 11, this rotation occurs. The motion is transmitted to the left and right synchronized shafts 53 via the pulley 47, round belt 55, and pulley 54.

When the rear timing pulley 56 at both ends of the shaft 53 rotates, the timing belt 66 stretched between the timing pulley 56 and the front timing pulley 64 rotates and is connected to the timing belt 66. The frame body 18 connected via the body 73 retreats. At this time, the roller 21 provided on the frame body 18
is transferred over the rail groove 17a of the rail 17 that supports the load of the door body 13. Along with that, this body rest 1
The side part of the door body 13, which is rotatably connected to the door body 8 via a hinge 19, also moves backward, but at first, the guide roller 27 of the door body 13 moves in the left and right direction of the guide groove 29 of the furniture body 11. 29a and then at the bent portion 29c, and moves outward in the left and right direction while retreating, so the door body 13 moves outward from the guide roller 27 as shown by the chain line in FIGS. 2 and 7.
The side opposite to one hinge also rotates in the direction in which it moves forward. At this time, the angle that the door body 13 makes with respect to the frame body 18 at the hinge 19 also changes, but this angle is uniquely determined based on the positional relationship between the frame body 18 and the guide roller 27 whose angle does not change.

Then, after the guide roller 27 moves toward the front-rear direction part 29b at the guide W429, the door body 13 moves toward the furniture body 1.
It retreats parallel to the side plate 11a of No. 1. Furthermore, for example, as shown by the chain line in FIG.
1, the pressing piece 76 of the frame body 18 is pressed by the roller 79 of the actuator 77a of the limit switch 77 on the rear side, the limit switch 77 is activated, and the electric motor 43 is stopped. . In this way, the front opening 12 of the furniture body 11 is opened, and the door body 13 is housed within the furniture body 11.

On the other hand, when the output shaft of the electric motor 43 is rotated in the opposite direction with the door body 13 open, the frame body 18 moves forward, and the door body 13 operates in the reverse process to the above-mentioned process. The front opening 12 of the furniture body 11 is closed by the door body 13. Note that when the door body 13 reaches the closed position, the suppressing piece 16 of the frame body 18 is pressed by the roller 79 of the actuator 77a of the front limit switch 77, the limit switch 77 opens, and the electric motor 43 stops.

In the end, the door body 13 moves as shown in FIG. 7, but the left and right door bodies 13 move symmetrically.

Further, when the door body 13 operates to open and close, that is, when the frame body 18 moves back and forth, upper and lower pinions 35 supported by a vertical synchronized shaft 34 common to the frame body 18 are provided on the rail 17 on the furniture body 11 side. By relocating while meshing with the locks 32, the movements of the upper and lower parts of the door body 13 are synchronized.

Therefore, even though the drive mechanism 41 is provided in a position biased toward the upper side of the door body 13, the upper side of the door body 13 may tilt backward when the door body 13 is opened, and the upper side of the door body 13 may tilt backward when the door body 13 is closed. The upper side does not tilt toward the building, and the door body 13 operates reliably and stably.

Furthermore, since the protrusion 35a of the pinion 35 provided on the frame body 18 and the guide slider 22 are engaged with the guide 1I117b of the rail 17, tilting of the frame body 18 in the left-right direction is also prevented.

According to the above configuration, since the door body 13 is opened and closed by the electric motor 43, it can be opened and closed easily and reliably.

Furthermore, by operating the separate transmitter 81, the user can control the electric motor 43 from any location, making the opening/closing operation even easier. Particularly, when a television, stereo, etc. that are similarly remotely controlled are housed in the furniture body 11, there is no need to go to the door body 13 just to open and close the door body 13, which is very convenient. Furthermore, it is also possible to control both the door body 13 and the television or the S-areo housed in the furniture body 11 using the same transmission R81, thereby making it even more convenient.

In addition, in the support mechanism 16 of the door body 13, the door body 13 is connected to the frame body 18 by a hinge 19, and the frame body 18 is connected to the rail 17 on the furniture body 11 side via rollers 21.
The guide roller 27 of the door body 13 is engaged with the guide W429 of the furniture body 11, and the door body 13
is firmly supported and its posture is reliably determined, so the drive mechanism 4 has a simple structure.
1, it becomes possible to electrically drive the door body 13.

Further, since the drive mechanism 41 converts rotation into linear motion using the pulleys 56, 64 and the belt 66, the structure is simple and compact. Moreover, the pulley is 56.6
4 and the belt 66 are the timing pulley 56, 64 and the timing belt 66, so there is no slippage and they operate reliably. Furthermore, the belt 6 is tightened by the tension roller 69.
Since 6 is under tension, - layer is certain.

Furthermore, since the left and right door bodies 13 are operated by one electric motor 4!343, the movements of both door bodies 13 can be reliably synchronized.

Further, since the N mower 43 is disposed at the upper rear part of the furniture main body 11, it is advantageous in terms of space, for example, when storing a television whose rear lower side protrudes.

Furthermore, since there is the vertical tuning mechanism 31, as mentioned above,
Even if the drive mechanism 41 is located on the upper side, the door body 13 operates stably, and therefore there is no need to provide drive mechanisms on both the upper and lower sides.

In addition, in the said Example, the number of the door bodies 13 was two, but the number of the door bodies 13 may be one.

〔Effect of the invention〕

According to the present invention, the following effects can be obtained.

In the furniture door device according to claim 1, the door body is horizontally rotatably connected by a hinge to a frame body supported on the furniture body via rails and rollers so as to be freely movable after movable. Since the guide bin is engaged with the guide groove provided in the furniture body, the door is rotated and driven to move between a position where it closes the front opening of the furniture body and a position where it overlaps with the inner surface of the furniture body. Not only can the body be firmly supported, but also the posture of the door body can be determined reliably.
It is also possible to reliably operate the door body with a drive mechanism that has a simple structure and does not take up much space. In this way, since the door body is driven by the electric motor, the opening/closing operation of the door body, which is driven in a relatively complicated manner as described above, becomes extremely easy.

Further, in the furniture door device according to claim 2, racks are provided at the upper and lower parts of the furniture body, and pinions supported by a common shaft at the upper and lower parts of the frame body are respectively engaged with the racks. Even if the mechanism is installed in a position biased towards the upper side of the door body, the movement of the upper part of the door body and the movement of the lower part can be reliably synchronized. There is no need to.

Furthermore, in the furniture door device according to claim 3, the transmitter and the reception and control device provided on the furniture body can:
Since the door body can be opened and closed by remote control, opening and closing becomes even easier. Especially when a remotely controlled television, stereo, etc. is housed in the furniture body, there is no need to go to the door just to open and close it, which is very convenient.
