  In the multiple sliding door device configured as described above, there are various means for attaching the second guide member to the stationary member, and as one of them, in other words, at a position away from the door pocket, An attachment member for attaching the second guide member is disposed at a position exposed from the door pocket, and the attachment member is arranged so that the thicknesses of the first and second door bodies from the surface of the stationary member on which the attachment member is arranged. It is supposed to have a protruding amount in the vertical direction.

  As described above, when the mounting member for mounting the second guide member is provided on the stationary member, the first door body is attached to the first guide member that is mounted on the stationary member before the second guide member. When the attachment member is already provided on the immovable member when performing the operation of arranging the door to be freely opened and closed, the attachment member and the door pocket are arranged on the first guide member of the first door body. Therefore, there is a need for a device that allows the first door member to be arranged on the first guide member without being affected by these attachment members and the door pocket.

  An object of the present invention is to facilitate the arrangement work of the first door body on the first guide member without being affected by the mounting member for the second guide member for guiding the second door body and the door pocket. Is to provide a multiple sliding sliding door device.

  The multiple sliding door device according to the present invention includes at least first and second door bodies, openings opened and closed by these door bodies, and the door bodies when the openings are opened. The first door body is guided to open and close by a first guide member attached to a stationary member, and the second door body is attached to the stationary member. The opening / closing movement is guided by the two guide members, and the position of the first door body when the opening is closed is closer to the door pocket than the position of the second door when the opening is closed. In the multiple sliding sliding door device, the stationary member is provided with an attachment member for attaching the second guide member at a position away from the door pocket, in other words, at a position exposed from the door pocket. And Moreover, the mounting member has a protruding amount in the thickness direction of the first and second door bodies from the surface of the stationary member on which the mounting member is disposed. The mounting member and the door pocket The distance between the first door body and the opening / closing movement direction is larger than the dimension of the first door body in the opening / closing movement direction, and the operator's hand placing the first door body on the first guide member is It is the size which can be inserted between the attachment member and the first door body and between the first door body and the door pocket.

  In this invention, the attachment member for attaching the 2nd guide member which guides the 2nd door body protrudes in the thickness direction of the 1st and 2nd door body from the surface of the stationary member in which this attachment member is arranged. Even if it has quantity, the space | interval in the opening / closing movement direction of the 1st and 2nd door body between this attachment member and a door pocket is larger than the dimension of the opening / closing movement direction of a 1st door body, and 1st Since the operator's hand that arranges the door body on the first guide member is sized to be inserted between the attachment member and the first door body and between the first door body and the door pocket, the first door The operation for arranging the body on the first guide member can be easily performed by the operator holding the first door body and lifting it up without being affected by the attachment member and the door pocket.

  In the present invention described above, the protruding amount of the first and second door bodies in the thickness direction with respect to the mounting member from the surface of the stationary member may be an arbitrary amount. It is to make it smaller than the distance from the said surface of a member to the surface by the side of the stationary member of a 1st door body, and the other example is the said stationary amount from the said surface of a stationary member to the stationary member of a 1st door body. The distance to the side surface is the same as or larger than this distance.

  Moreover, the arrangement position in the thickness direction of these door bodies about the 1st and 2nd door bodies may be arbitrary positions, for example, the arrangement position of these door bodies is the thickness of these door bodies. Another example is that the position of these door bodies is set to the same position in the thickness direction of these door bodies, and one door body is placed inside the other door body. It is to be a nesting type that can be invaded.

  The amount of protrusion in the thickness direction of the first and second door bodies of the mounting member from the surface of the stationary member is larger than the distance from the surface of the stationary member to the surface of the first door body on the stationary member side. In this case, the second guide member attached to the attachment member can be penetrated into the first door body, and when the second guide member is penetrated into the first door body in this way. The second door can be a telescopic door that can enter the first door.

  Furthermore, in this invention, the position of the edge part by the side of the door of an attachment member may be arbitrary positions, For example, the position of the edge part by the side of the door of an attachment member is the door edge side of a 2nd guide member. It is to make it the same or substantially the same as the position of the end of the.

  According to this, it becomes possible to make the part of the 2nd guide member attached to an attachment member into the long part of the 2nd guide member including the edge part by the side of the door of the 2nd guide member, and to the attachment member. 2 The mounting strength of the guide member can be increased.

The structure for doing so may be an arbitrary structure. For example, at least one of the first door body and the second door body has moved the second door body, which has been retracted together with the first door body to the position where the opening is opened, is moved to the closed side by a predetermined distance. Sometimes, a locking member is provided in which the first door body and the second door body are connected and locked together, and when the second door body is moved further to the closing side, both door bodies are engaged with this engagement. It is configured to move together by the stop member. Another example is to always connect the first door body and the second door body and use an interlocking mechanism for interlocking and opening and closing these door bodies.

  An example of such an interlocking mechanism includes two rotating bodies arranged in the first door body apart from each other in the opening and closing direction, and hung around these rotating bodies and coupled to an immovable member. And a string-like member that is coupled to the second door body on the opposite side of the location where it is coupled to the stationary member.

  According to this interlocking mechanism, when either one of the first door body and the second door body is moved by manual operation or automatic movement means, the first door body and the two rotating bodies are connected to each other. The second door body moves in conjunction with each other, the first door body becomes a low-speed door body that moves at a low speed, and the second door body becomes a high-speed door body that moves at a high speed.

  The string-like member in this interlocking mechanism may be a metal wire, a synthetic resin string, a fiber string, a composite material of these, a flat belt, a timing belt, a chain, etc. But it is optional.

  The form of the door pocket described above is arbitrary, and this door pocket may be, for example, an externally exposed door pocket that can be visually recognized from the outside, or a wall storage type door pocket that is housed inside a wall. These door pockets may be double-sided door pockets having portions covering both sides in the thickness direction of the first and second door bodies housed inside the door pocket, and the thicknesses of the first and second door bodies. A single-sided door pocket having a portion covering only one side in the vertical direction may be used.

  In addition, the first guide member and the second guide member in the multiple sliding door device according to the present invention may guide the upper part of the first door body and the second door body, or may guide the lower part, It is also possible to guide both the bottom and the bottom. That is, the present invention can also be applied to an upper guide type multiple sliding type sliding door device in which the movement guidance of the first and second door bodies by the first and second guide members is performed above the door bodies. The present invention can also be applied to a lower-guiding multiple sliding sliding door device performed at the lower part, and can also be applied to an upper and lower both-guiding multiple sliding sliding door device performed at both the upper and lower portions of the door body.

  Further, the present invention can also be applied to a sliding door device in which the first and second door bodies are upper-suspended door bodies suspended from the first and second guide members.

  In addition, when the door body is a top-suspended door body, the top-suspended system may be a guide rail system using a guide rail or a slide rail system using a slide rail.

  The guide rail system is a guide rail attached to a stationary member as a guide rail, and a roller provided on the door body is slidably engaged with the guide rail. The slide rail system is a stationary rail system. A guide member attached to the member is a slide rail, and a slide bearing provided on the door body is slidably engaged with the slide rail.

  Further, the present invention can be applied to a multiple sliding door device having two door bodies, and also to a multiple sliding door device having three or more door bodies. Can be applied.

  Further, the present invention is applied to a multiple sliding sliding door device in which at least one of the first and second door bodies is opened and / or closed by an automatic closing device. In addition, the present invention is also applicable to a multiple-sliding type sliding door device in which at least one of the first and second door bodies is manually opened and / or closed. be able to.

  Furthermore, the opening and closing movement form of the first and second door bodies guided by the first and second guide members is arbitrary. In other words, the first and second guide members that guide the first and second door bodies may be those that guide these door bodies linearly or may guide them in a curved line. In order to close the second door body close to the building frame or the like, the first and second guide members move the first and second door bodies substantially in parallel in the thickness direction of these door bodies. It may be moved in the width direction of the door body (the opening / closing movement direction of the door body).
