  A guide member 27 is attached to the lower end surface of the central door 5, while a guide rail 31 is installed on the floor surface 29 below it, and the tip of the guide member 27 slides in the groove of the guide rail 31. It is possible to fit. Further, J-shaped guide brackets 33 are attached to lower ends of the front surface 5a and the rear surface 5b of the central door 5, respectively.

  On the other hand, a groove 35 is provided in each of the lower end surfaces of the front and rear doors 3 and 7, and both ends in the left-right direction of the groove 35 are closed. The guide bracket 33 is attached so that the front end portion faces outward in the front-rear direction, supports the doors 3 and 7 on both front and rear sides, and the front end portion is slidably fitted in the groove 35.

  FIG. 3 is a plan view of the sliding door 1 when the opening 9 is opened. In FIG. 3, the hanging door interlocking tool 25 and the guide bracket 33 are omitted. FIG. 4 is an enlarged view of a portion IV in FIG.

  As shown in FIGS. 3 and 4, the front and rear doors 3 and 7 have the same left and right width, and the left and right widths are smaller than the central door 5. A long handle 37 extending in the vertical direction is attached to the door end side (right side end) of the front door 3 and the door end side (left side end) of the rear door 7.

  The handle 37 is made of, for example, an aluminum material or a resin material, and has the same vertical dimension as the doors 3 and 7. The handle 37 has an F-shaped cross section, a fixed portion 37a fixed to the rear surfaces 3b and 7b of the doors 3 and 7, a hook portion 37b on which a finger is hung, a positioning portion 37c for positioning the handle 37, have.

  The fixing portion 37a has a rectangular plate shape that is elongated in the vertical direction, and has a lateral width that is greater than the difference between the lateral widths of the doors 3 and 7 and the central door 5. And the fixing | fixed part 37a is fixed to the rear surface 3b, 7b of each door 3 and 7 in the left-right direction inner side edge part, and protrudes in the left-right direction outer side. This projecting dimension coincides with the difference between the left and right widths of the doors 3 and 7 and the central door 5.

  The hook portion 37b has a rectangular plate shape elongated in the vertical direction, and extends forward from the protruding end of the fixed portion 37a. Therefore, a hook recess 39 opened forward is formed by the hook portion 37b, the protruding portion of the fixed portion 37a, and the end surfaces 3c and 7c on the side where the handle 37 of each door 3 and 7 is attached. The hook portion 37b has a front-rear width of about half of the thickness of each door 3, 7, for example, a front-rear width of about 20 mm when the thickness of the door 3, 7 is about 36 mm. The front-rear width may be equal to or less than the thickness of the doors 3 and 7. Further, the hook portion 37b has a triangular cross section, and the left and right outer end surfaces are along the front-rear direction, while the left and right inner end surfaces are inclined inward in the left and right directions toward the front. Since it is inclined in this way, it is easy to hook a fingertip.

  The positioning portion 37c protrudes forward from the fixed portion 37a. This positioning portion 37c has a front-rear width smaller than the thickness of each door 3 and 7 in order to avoid a doorwheel (not shown), and contacts the end surfaces 3c and 7c on the side where the handle 37 is attached. It touches. The distance between the positioning portion 37c and the hooking portion 37b coincides with the difference between the left and right widths of the doors 3 and 7 and the central door 5.

At this time, since the left and right widths of the front door 3 and the rear door 7 to which the handle 37 is attached respectively coincide with the left and right widths of the central door 5, the doors 3 and 7 are at the door end side end of the central door 5. Therefore, the effective opening area of the opening 9 can be ensured without protruding toward the door end.

  When closing the opening 9 thus opened, first, a finger is inserted from the front into the hooking recess 39 of the rear door 7. At this time, since the space S is formed between the hook portion 37b and the central door 5, a finger can be safely inserted. Next, the door 7 is moved by pulling the handle 37 to the left. And when the front-end | tip part of the guide bracket 33 attached to the rear surface 5b of the center door 5 contact | abuts to the obstruction | occlusion end of the left side in the groove | channel 35 of the rear door 7, the center door 5 will turn into the rear door 7. In conjunction with this, the slide 9 moves to the left, and the opening 9 is closed.

  On the other hand, when opening the opening 9 from the closed state, a finger is inserted into the hook recess 39 of the rear door 7 from the front, and the door 7 is slid to the right. When the front end of the guide bracket 33 attached to the rear surface of the central door 5 comes into contact with the closed end on the right side of the groove 35 of the rear door 7, the central door 5 is interlocked with the rear door 7. Then, it slides to the right and the opening 9 is opened. Here, when the opening 9 is fully opened, the finger inserted into the hooking recess 39 is in a state of being hooked on the hooking portion 37b, and between the hooking portion 37b and the central door 5 on the front side thereof. Since the space S is secured in this way, it is possible to avoid the fingers being pinched by the hook portion 37b and the central door 5 as described above.
