  In the double sliding type sliding door device shown in the above-mentioned Patent Document 1, the second guide rail for guiding the opening and closing movement of the second door body is attached to the first door body. As the overall weight increases, the structure of the first door body becomes complicated. For this reason, in order to install the conventional double-sliding type sliding door device in the field, first the first guide rail is attached to guide the opening and closing movement of the first door body, and then the first door body is mounted. In order to be movable along the first guide rail, an operation of movably engaging the first roller with the first guide rail is performed. In this operation, the operator lifts the entire first door body. Is done by. However, lifting the first door body to which the second guide rail is attached requires great labor for the operator. For this reason, the device which aims at weight reduction of a 1st door body is calculated | required.

  An object of the present invention is to provide a multiple sliding sliding door device that can reduce the overall weight of the first door body for opening and closing the opening together with the second door body.

  The multiple sliding door device according to the present invention includes at least first and second door bodies, and first and second guide members that guide the door bodies in the opening / closing movement direction, The opening is opened and closed by the movement of the first and second door bodies in the same direction, and the opening is opened and closed in the opening and closing movement direction when the second door body moves forward toward the closing side rather than the first door body. Closed by the shifted first and second door bodies, the first guide member is disposed above the first door body, and an upper portion of the first door body is movably engaged with the first guide member. A first engaging portion is provided, and the first door body is a top-suspended door body suspended from the first guide member at the first engaging portion, and the second guide member is Arranged above the second door body, the upper part of the second door body is movable to the second guide member In the multiple pulling type sliding door device which is provided with a second engaging portion to be engaged, and the second door body is an upper hanging door body suspended from the second guide member by the second engaging portion, The first guide member for the first door body is attached to an immovable member that is stationary with respect to the first and second door bodies, and the second guide member for the second door body. Is attached to an immovable member which is immovable with respect to the first and second door bodies.

The second guide member for guiding the opening and closing movement is also attached to the stationary member that is stationary relative to the first and second door bodies.

  That is, in the present invention, unlike the first door body of the conventional multiple sliding door device, the second guide member for the second door body is not attached to the first door body.

  For this reason, according to this invention, the weight reduction of the whole weight of a 1st door body can be achieved. Thereby, when installing the multiple-sliding type sliding door device on the site, an operator can disengage the first door body in order to engage the first engagement portion provided on the upper portion of the first door body with the first guide member. The effort required to lift the whole will be reduced.

  Furthermore, according to the present invention, since the second guide member for the second door body is not attached to the first door body, the structure of the first door body can be simplified.

  In the present invention, the type, structure, etc. of the immobile member are arbitrary. As a first example, the immovable member to which the first guide member is attached is an upper frame member (so-called “eyeless”). The immovable member to which the guide member is attached includes a first frame member disposed on the door end side of the first and second door bodies, and a second member disposed on the door bottom side of the first and second door bodies. Examples of the frame member include a frame member in which the second guide member is installed between the first frame member and the second frame member. Further, as a second example of the immovable member, an example in which the immovable member to which the first and second guide members are attached is an upper frame member.

The spring force is accumulated in the spiral spring of the spiral spring mechanism by the string-like member 61 fed out from the automatic closing device 60. Then, when the hand is released from the gripping portion 58, the second door body 22 is automatically closed and moved by the accumulated spring force, and the first door body 21 also has the speed of the second door body 22 via the interlocking mechanism 50. Close and move at half speed. For this reason, the sliding door device according to the present embodiment is a self-closing type sliding door device in which the two door bodies 21 and 22 automatically move to the position shown in FIGS. 1 and 2 where the doorway 2 is fully closed. It has become.

  Further, as shown in FIGS. 4 and 7, a rotary brake device 70 is disposed on the above-described first component portion 21A of the first door body 21, and FIG. A further enlarged view of this brake device 70 is shown. As shown in FIG. 4, the brake device 70 in which the storage case is indicated by a two-dot chain line includes two brackets 33 provided for each of the first rollers 32 of the first door body 21. It is attached to the bracket 33 on the door end side. That is, in the present embodiment, the bracket 33 is a member for attaching both the first roller 32 and the brake device 70 to the first door body 21, and the member is shared.

  As shown in FIG. 12, the rotary brake device 70 has a pinion gear 72 that meshes with the rack member 71. The rotation center shaft 73 of the pinion gear 72 has a thickness of the door body 21 as shown in FIG.
