In addition, the aspect in which the slide rail can be further expanded and contracted in the direction in which one of the two opening / closing bodies 10 and 10 is separated from the other (outward in the width direction of the opening 5) is not limited to the above aspect. Alternatively, both travel type slide rails that can be expanded and contracted may be employed. In addition, a restricting portion such as an appropriate stopper is provided to maintain a state in which the one opening / closing body 10 is in the closed position and the other opening / closing body 10 is in a position substantially coincident with the one opening / closing body 10. It may be. Further, the slide rail is not limited to a mode in which one of the opening / closing bodies 10 can be slid to a position where the other opening / closing body 10 substantially coincides with the one opening / closing body 10 in a state where the one opening / closing body 10 is in the closed position. It is good also as an aspect which can be slid to a position.

The opening / closing device 1 according to the present embodiment configured as described above is opened and closed as follows, for example.
1A, FIG. 2 and FIG. 3A show a state in which the opening 5 is closed with the opening / closing bodies 10 and 10 (slide rails 26 and 26) as the storage positions. In this state, the opening and closing bodies 10 and 10 are arranged side by side so that the front surfaces 11 and 11 and the rear surfaces 12 and 12 are substantially coplanar. That is, in this closed state, the front and rear surfaces 11 and 11 of the opening and closing bodies 10 and 10 are substantially flush with each other, and the rear surfaces 12 and 12 of the opening and closing bodies 10 and 10 are substantially flush with each other. The bodies 10 are arranged side by side along the width direction of the opening 5.
When opening the opening 5 from the closed state, as shown in FIG. 3B, one opening / closing body 10 is set to the front position (see also FIG. 5B). And as shown in FIG.3 (c), this one opening-closing body 10 is slid toward the other opening-closing body 10 side adjacent, and these adjacent opening-closing bodies 10,10 are made to overlap each other back and forth. It is good also as an aspect which arrange | positions and makes the opening 5 open. Or it is good also as an aspect which opens the opening 5 by sliding the other opening-closing body 10 made into the accommodation position with respect to one opening-closing body 10 made into the front position toward the one opening-closing body 10 side ( (See also Fig. 5 (a)). In addition, when one opening / closing body 10 is set to the front position in this way, the butted end portions of the adjacent opening / closing bodies 10 and 10 may be chamfered so as not to interfere with each other.

When one of the two opening / closing bodies 10, 10 is moved in a direction away from the other (outward in the width direction of the opening 5), the one opening / closing body 10 is set to the front position as described above. Then, as shown in FIG. 3D and FIG. 5B, by sliding the one opening / closing body 10 toward the outer side, it is separated from the other opening / closing body 10, and the width direction of the opening 5 The middle side can be opened.
In addition, according to such a structure, the opening-and-closing body 10 and 10 of both sides can be made into a front position, and the width direction intermediate side of the opening 5 can be open | released largely like a draw by sliding to the direction which mutually separates, Further, substantially the entire opening 5 can be opened. Further, the slide dimension in the direction in which one opening / closing body 10 is separated from the other opening / closing body 10 may be a dimension that allows the opening 5 to be opened largely. At least a finger or the like can be inserted between the opening / closing body 10 and the other opening / closing body 10. It is good also as a dimension in which the space to be formed is formed.
Moreover, when closing the opening 5, it is good also as an aspect which closes the opening 5 by each opening-closing body 10 and 10 (slide rail 26, 26) made into the front position. In this case, when opening the opening 5, one opening / closing body 10 may be in the storage position, and any opening / closing body 10 may be slid to open the opening 5.

According to the opening / closing apparatus 1 according to the present embodiment, a plurality of the opening / closing bodies 10, 10 can be arranged so that the front and rear surfaces 11, 11, 12, 12 are substantially flush with each other in the closed state. However, the upper mechanism 20 that guides the upper ends of the opening / closing bodies 10 and 10 can be made compact.
That is, in a state where the opening 5 is closed by the plurality of opening / closing bodies 10, 10, the plurality of opening / closing bodies 10, 10 have their front and rear surfaces 11, 11, 12, 12 substantially in the same plane. Arranged. Therefore, since the plurality of opening / closing bodies 10 and 10 are arranged horizontally and flatly, a clean impression can be given and the appearance can be improved.

Further, the slide rails 26 and 26 for guiding the upper ends of the plurality of opening and closing bodies 10 and 10 are stretched at substantially the same height position just below the lower surface 21a of the upper frame 21 (the top surface of the opening 5). Are held by the rail holding portion 23 so as to be freely displaceable between a storage position positioned so as to be aligned along the front and a front position protruding forward from the storage position. Therefore, the upper mechanism 20 that guides the upper end side of the opening / closing body 10 can be made more compact than a structure in which the two rails are arranged vertically and front and rear.
Further, since the slide rails 26 and 26 are freely displaceable between the storage position and the front position, the degree of freedom when the opening / closing body 10 is slid to be opened can be improved. Can be improved. That is, for example, one of the opening / closing bodies 10, 10 adjacent to the opening / closing body 10 is slid and the other opening / closing body 10 is slid to open the opening 5. Can be opened. Contrary to the above, the opening 5 is opened by sliding any one of the opening / closing bodies 10 and 10 with the one opening / closing body 10 at the front position and the other opening / closing body 10 as the storage position. Can do.

  In the present embodiment, the rail holding portion 23 that holds the slide rail 26 so as to be freely displaceable between the storage position and the front position is provided on the lower surface 21a (top surface of the opening 5) side and the slide rail 26 side. It is set as the link member 23 each connected to. Therefore, for example, the front-rear dimension of the rail holding portion (link member) 23 in the storage position can be reduced as compared with a case in which a slide rail is guided in the front-rear direction. Instead of such a mode, a runner member provided on the upper surface side of the slide rail 26 and a rail provided on the upper frame 21 (the top surface of the opening 5) side for guiding the runner member in the front-rear direction. You may make it comprise a rail holding part.

  Further, in the present embodiment, the slide rails 26 and 26 of the two opening / closing bodies 10 and 10 can be further expanded and contracted in a direction in which one of the opening / closing bodies 10 and 10 is separated from the other. Therefore, it can be opened in a drawing manner, and can be opened in a drawing manner as described above. In addition, when the opening / closing device 1 is installed inside an existing sliding window, the summing unit of the existing sliding window is moved by moving one of the opening / closing bodies 10 away from the other. It is also possible to easily operate a locking member such as a crescent lock provided on the. Accordingly, the opening / closing device 1 can be suitably employed as an inner window of an existing outer window. A structure in which the slide rails 26, 26 of the two opening / closing bodies 10, 10 can be expanded / contracted only to the other side without further expanding / contracting in the direction of separating one of the opening / closing bodies 10, 10 from the other. It is good.

  Furthermore, in this embodiment, the rail holding part (link member) 23 is coupled to the slide rail 26 via the rail attachment member 24 provided with a cover piece 24b that covers the front side of the slide rail 26. In addition, the opening / closing body is provided with a cover piece 14b that covers the front side of the slide rail 26 in the open state while being overlapped with the cover piece 24b of the rail attachment member 24 in the closed state. The slide rail 26 is connected via the member 14. Therefore, since the front surface side of the slide rail 26 can be covered by the cover pieces 24b, 14b of the rail mounting member 24 and the opening / closing body mounting member 14, the slide rail 26 becomes inconspicuous from the front side, and the appearance is improved. Can do. Moreover, since the front side of the slide rail 26 is covered, it is possible to suppress the entry of articles, fingers, and the like into the slide rail 26. Note that both or one of the rail attachment member 24 and the opening / closing body attachment member 14 may not be provided.

In addition, in this embodiment, although the opening / closing apparatus 1 provided with the two opening / closing bodies 10 and 10 is illustrated, it is good also as what was provided with the three or more opening / closing bodies. In this case, the upper mechanism may be appropriately deformed according to the number of opening / closing bodies.
In this embodiment, an example in which the rail holding portion (link member) 23 is connected to the upper frame 21 is shown. However, without providing the upper frame 21, an appropriate amount is provided on the top surface side of the opening 5. It is good also as an aspect connected via a connection member.
