The door body 3 is attached by engaging with the engagement receiving portion 53 of the engagement brake 1/54 fixed to the front surface of the door body 41.

This sea urchin, this I7! It is easy to incorporate the leisure equipment into the furniture main body member 5.

Next, the operation of the door device of this embodiment will be explained.

To hear the door body 3 in the closed state, first slide the door body 3 forward. In other words, when you pull the door body 3 forward,
The front and rear movable rail 23 slides forward with respect to the front and rear fixed rail 22 of the front and rear slider 21, and in front of this (i:Q +J on the front side of the C co-moving 1 knoll 23, the left and right slider 4
The door body 3 connected to 1 through the connecting plate 6G moves toward 11.

When operating the front and rear slider 21 as described above, the rollers 24 and 25 provided on each rail 22 and 23 make the movement of the front and rear movable rail 23 smooth, and the left and right synchronization mechanism as described in 11a. By plowing 31, the glide J of both longitudinally movable rails 23 located on both sides of the furniture main body member 5 is synchronized, so that the door body 3 tends to tilt in the left-right direction.

In addition, when sliding the door body 3 forward, both [J-ra holders 51.
A position control roller 57 and a guide roller 5B provided on the holder plate 52 slide along both holder plates 13, respectively, and guide the holder in the front and rear direction.

In addition, with the movement of the front and rear movable rail 23 to the front I),
The vertical synchronization 7-memory 73 engaged with the engagement plate 72 provided on the rear movable rail 23 is
3b as a center, and the vertically synchronized shaft 74 fixed to this shaft receiving portion 73b also rotates.

As the shaft 74 rotates, the rear arm rest 76 to which the supported portion 78a is fixed to the shaft 14 is rotated.
rotates, and accordingly, the back-and-forth movable plate 78 connected to this rear arm body 76 moves forward by an amount equal to the amount of movement of the back-and-forth movable rail 23. Therefore, due to the function of the vertical synchronization mechanism 71, the movement of the lower part and the upper part of the door body 3 is synchronized, so that the door body 3 does not tilt backward ^η.

Furthermore, when the door body 3 is pulled out forward, the support rollers 55 and 56 provided on the front sides of the left and right sliders 41 are positioned slightly above the support rail 62. Therefore, in this state as well as in the closed state of the door body 33, the load of the door body 3 is supported by the left and right sliders 41 in the folded state and the upper support rail 80 of the vertical tuning mechanism 71.

Next, the door body 3 is slid to the left by the left and right slider 41, and the door body 3 is placed on the front side of the external door body 4 (E) to open the front opening 2 of the furniture main body member 5. In other words, the left and right fixed rails 4 fixed to the front and rear movable rails 23
2, the inner left and right movable rail 44 and the door body 3 are engaged and the outer right movable rail 43 is slid (
From this, slide the door body 3 to the left.

At this point, the right roller holder 51 fixed to the outer right movable rail 43 is provided with a
7 is a position regulating rail G1 fixed to the frame body 11
This prevents the door body 3 from moving in the IQ direction. Along with this, the left side [1-Guide 1 provided on the holder 52]-R! ) 11 comes into contact with the front surface of the rear vertical plate portion 66c of the connecting plate 66 of the adjacent door body 4, and the adjacent door body 4 opens! It prevents the IJ block and also prevents the opening of the door body 3 from hitting the rear block J.

In addition, the left and right sliders 41 supporting the lower part of the door body 3 are supported only by the front and rear movable rails 23, and the front and rear movable rails 23 have a slight play due to the front and rear fixed rails 22. Since it is supported, door body 3
When the left and right sliders 41 are slid half the length in the lateral force direction, the extended left and right sliders 41 tilt slightly due to the load of the door body 3, and the support rollers 5G provided on the sides of the outer left and right movable rails 43 move toward the adjacent side. The support rail 62 provided on the furniture main body member 6 is brought into contact with the support rail 62 . That is, at the stage when the left and right sliders 41 are extended and it is no longer desirable to apply the load of the door body 3 to the left and right sliders 41, the load of the door body 3 is supported by the support rollers 56.

Therefore, the durability of the left and right sliders 41 is increased, and the left and right movement of the door body 3 becomes smoother.

As described above, the sliding mechanism of the door body 3 in the left-right direction includes the left-right fixed rail 42 fixed to the front-back movable rail 23 and the left-right movable rail 43 slidably supported by the left-right fixed rail 42. .44, so
Since the amount of sliding of the door body 3 in the front-rear direction does not require much precision, manufacturing becomes easy. In addition, the roller 56 that supports the load of the door body 3 comes into contact with the rail 62 on the adjacent door body 4 side after the left and right sliders 41 have expanded to a certain extent, so that the rail 62 is approximately the width of the door body 4. It is sufficient that the lengths are the same, and no great precision is required for the joints of the respective rails 62 provided corresponding to the respective door bodies 3 and 4.

Note that the movement of the door body 3 is performed by moving the horizontal plate portion 66 of the connecting plate 6G.
The flange 68 provided at the door a is locked by coming into contact with the side edge of the connecting plate 66 of the adjacent door body 4.

By the way, as mentioned above, in the vertically synchronized machine R471, the arm bodies 76 and 77 that connect the back and forth moving plate 78 that controls the upper support roller 8o and the fixed plate 75 fixed to the furniture main body member 5 are connected to each other. Since the distance between the shaft portions 76b and 77 which are pivotally connected to the forward and backward moving plate 78 is smaller than the distance between the supported portions 7Ga and 77 which are pivotally connected to the fixed plate 75, As shown by the solid line, when the three bodies 3 are placed backwards (17), the front i! In other words, when the door body 3 is turned 11, the longitudinal movement plate 78 tilts forward and to the left.
Since the upper support roller 8oS provided in the upper support rail 81 of the door body 3 is located closer to the center thereof,
This door body 3 is supported in a more stable state, and when the door body 3 is opened, the upper support roller 80 is located closer to the other door body 4, so that the door body 3 is more easily supported. Listening becomes possible.

Then, in order to close the opened door body 3 again, this door body 3
Just slide it to the right, then slide it backwards.

In the above embodiment, the front opening 2 of the furniture body 1 is opened and closed by a pair of door bodies 3.4, but the number of door bodies 3, 4 is not limited to two; Three or more door bodies may be provided facing the opening 2.

[Efficacy of invention Song Dynasty]

According to the present invention, the left and right slider that allows the door body to move left and right is constituted by the left and right fixed rails that are fixed to the front and rear movable rails, and the left and right movable rails that are supported by the left and right fixed rails so that they can move freely. , the sliding movement m of the door body in the front-rear direction does not require a large amount of time t5, and since the left and right movable rails are provided with rollers that slide on the rails fixed to the furniture body, the load on the left and right sliders is reduced. I wish I could make it smaller.
6. The operation of the door body is now smoother, and the rollers are brought into contact with the rail on the adjacent door side with the left and right sliders extended over a predetermined length. It only needs to be of a certain length, and the joints between the rails corresponding to each door body do not require much opening.
Therefore, manufacturing is also facilitated.
