2. Description of the Related Art An outset type sliding door of this type is found, for example, in Japanese Patent Laid-Open No. 2001-227249. There, a pair of upper and lower guide rails and a pair of left and right vertical frames that connect the left and right ends of both rails constitute an opening frame,
A pair of left and right sliding door panels are supported by the opening frame so as to be openable and closable in the left-right direction. The guide rail and vertical frame are
Each is formed of an aluminum strip, and in each case, a fastening seat to be screwed to the inner surface of the opening of the cabinet is integrally formed.

The sliding door of the present invention is provided with a self-closing mechanism. When the sliding door panel is closed to a predetermined position, the self-closing mechanism automatically closes the sliding door panel to the closing position thereafter.
Keep the sliding door panel closed. A self-closing mechanism of this type is known, for example, from Japanese Patent Publication No. 5-23763. There, a self-closing mechanism is provided between the drawer and the side wall of the drawer frame.The self-closing mechanism slides a slider that is biased to move freely by a spring and a pair of pins provided on the slider. The guide member and the switching pin provided on the drawer side for switching the posture of the slider are used as the element members. When the drawer is opened from the closed position, the slider moves along with the switching pin while resisting the biasing force of the spring. At the end of the guide groove, a switching groove for switching the attitude is provided, and when one pin of the slider enters the previous switching groove, the slider is switched to the connection standby attitude and held at the corresponding position. When the posture of the slider is switched, the engagement state between the switching pin and the slider is released, so that the drawer can be freely opened.
When the drawer is closed, the switching pin is re-engaged with the slider to switch the slider to the connecting posture, so that the drawer is pulled by the spring.

The projecting length of the front base portion 52 is set to be about half of the projecting length of the rear base portion 53, and the runner 16 is received by the inner end surfaces of the two 52 and 53 formed in a stepwise manner in the left-right direction. Stoppers 52a and 53a are provided so as to project. Figure 8
As shown in FIG. 5, the stoppers 52a and 53a contact the concave circumferential groove of the roller 25 and regulate the movement of the runner 16 in the direction of coming out of the upper rail 2.

A slide groove 56 that opens upward is formed in the guide portion 54, and a first pin 61 and a second pin 62 of a slider 49, which will be described later, are slidably engaged with the slide groove 56 that is opened in the front wall of the guide portion 54. The left and right laterally long guide grooves 48 are formed respectively, and the entire slider 49 is incorporated into the slide groove 56 from the opening upper surface side. The holder 47 is the upper rail 2 as shown in FIG.
With respect to the bottom surface side, it is assembled and fastened with a total of three screws 57. Therefore, the guide rail 6 includes a front base portion 52.
The portion where the rear base portion 53 and the rear base portion 53 fit is cut off in advance.
In addition, the holder 4 that is assembled to the left end of the upper rail 2
Reference numeral 7 is the same component as the holder 47 and is mounted by reversing the left and right. Therefore, in the holder 47 assembled to the left end of the upper rail 2, the front and rear projection lengths of the front base portion 52 and the rear base portion 53 are reversed in relation to each other (see FIG. 12).

In FIG. 1 and FIG. 5, the slider 49
Is a plastic molded product in which a hook-shaped buffer arm 60 is integrally formed on the inner end side of a plate-shaped base 59, and the first pin 61 slidably guided to the guide groove 48 on the left and right of the front surface of the base 59. The second pin 62 is integrally provided, and a catching groove 63 that allows the operation pin 46 to be engaged and disengaged is cut out at the lower end of the base 59.

The slider 49 is fitted into the slide groove 56 of the holder 47 from above and the first and second pins 61 and 62 are guided and engaged in the guide groove 48.
As shown in 0, one end of the spring 50 is hooked on a locking pin 64 provided on the upper rear surface of the slider 49, and the other end of the spring 50 is hooked on a pin 65 fixed to the holder 47 side to slide the slider 49 into a sliding door. Always pull back and urge the panels 4R and 4L toward the closed end. Incidentally, the tension of the spring 50 acts in a direction in which the slider 49 is always rotationally displaced in the clockwise direction. However, the first and second pins 61,
When 62 is simultaneously engaged with the guide groove 48, the upper wall of the guide groove 48 receives the previous moment via the first pin 61, so that the slider 49 maintains the connecting posture shown in FIG. 10B. to continue.

In order to switch the slider 49 between the connection standby position and the connection position in conjunction with the opening / closing operation of the sliding door panels 4R and 4L, the inner end of the guide groove 48 is bent upward as shown in FIG. The switching groove 67 is formed in a communicating manner. As described above, since the clockwise moment acts on the slider 49, when the first pin 61 is guided into the switching groove 67, the slider 49 moves.
Is tilted and displaced as shown in FIG.
0 is received by the regulation wall 68 at the inner end of the slide groove 56, and switches to the connection standby position. In this state, since the first pin 61 is received by the switching groove 67, the slider 49 is not pulled back to the closed end side by the spring 50, and the connection standby posture is continuously maintained. At this time, the capture groove 63 is obliquely inclined, and the opening at the lower end thereof faces the movement trajectory of the operation pin 46 fixed to the runner 16.
In FIG. 5, reference numeral 69 is an end cap fitted and fixed to the side end of the lower rail 3.

Now, from the above state, the sliding door panel 4 on the right side

Tilt operation. As a result, the first pin 61 disengages from the switching groove 67 and moves to the guide groove 48 side, and at the same time, the operation pin 46 completely engages with the catching groove 63. When the first pin 61 moves to the guide groove 48, the previous movement restricting action of the first pin 61 is released, so that the slider 49
Is forcibly moved to the closing side by receiving the urging force of the spring 50, and is maintained in the connecting posture shown in FIG.
Therefore, when the sliding door panel 4R is closed to a predetermined position, the sliding door panel 4R can be closed by the self-closing mechanism 5 and the closed state can be maintained. Panel 4R and slider 4
9 Operation pin is captured via 46, and sliding door panel 4R
It closes and eliminates the rebound caused by the reaction force.

Also in the left sliding door panel 4L, the sliding door panel 4L is similarly closed by the self-closing mechanism 5,
It can be kept closed. By reversing the above procedure, the operation pin 46 is disengaged from the catching groove 63, so that the sliding door panels 4R and 4L can be fully opened. That is, in the state where the first pin 61 is fitted in the switching groove 67, the slider 49 is held in the connection standby posture by the spring 50, and only in this state the operating pin 46 is held.
Can be engaged with and disengaged from the capture groove 63.
