It is good. In this case, the lower rail 24 may be provided on the floor surface or embedded in the floor. In addition, various opening frames can be used.

These folding doors 10 and 10 have substantially the same configuration, and each has a structure in which adjacent door plates 11 and 11 of a plurality (four in the illustrated example) of door plates 11 are connected to each other by a connecting member 18 so as to be foldable. Has been.
In this embodiment, each folding door 10 connects the adjacent door plates 11 and 11 by the connecting member 18 so that each door plate 11 may be folded substantially parallel as shown in FIG.1 (b) and FIG.3 (b). It is made the structure. In the illustrated example, each folding door 10 has a structure that is folded substantially in parallel so that opposing surfaces of adjacent door plates 11 are close to or in contact with each other.

  As shown in FIGS. 2 and 3, the connecting member 18 is paired up and down, and spans the upper end surface and the lower end surface of the side end portion on the connecting side in the door width direction of the adjacent door plates 11, 11. Thus, it is set as the plate shape arrange | positioned. The connecting members 18 and 18 are provided with insertion holes for stoppers (rotating shafts) that serve as connection-side rotation fulcrums 17 of the door plates 11 such as pins, bolts, and screws. Each connecting member 18 is attached to the upper end surface and the lower end surface of the side end portion on the connecting side of 11 and 11. By these connecting members 18, the door plates 11 are connected to each other so as to be rotatable about the connecting side rotation fulcrum 17 and can be folded substantially in parallel. Further, the side end portion on the connection side of each door plate 11 protrudes outward in the door width direction so as not to cause interference and rubbing when the folding door 10 is opened and closed, and the connection side rotation fulcrum 17 is provided. The arc shape has a substantially circular center. In the example of the figure, the both side edge parts 12 and 13 of the door width direction of each doorplate 11 are shown as the circular arc shape.

For example, a recess that embeds a mounting blade, a mounting block, or the like is provided on a surface that faces each other when folded or an end surface of the connection side, and a digging hinge or the like disposed so as to be embedded in this recess A hinge such as a hidden hinge may be employed as the connecting member. In addition, it is possible to employ various connecting members such as hinges. In this case, a hinge pin such as a hinge may be grasped as the connecting side rotation fulcrum.

As shown in FIG. 2, each door plate 11 is vertically elongated and has a substantially rectangular flat plate shape. In this embodiment, the door plate 11 has a relatively thin thickness. The thickness dimension of the door plate 11 may be thinner than that of a conventional folding door, which is generally about 25 mm to 35 mm, and may be about 10 mm to about 20 mm, for example.
1 and 3B, each door plate 11 is rotatable with respect to the upper and lower rails 22 and 24 disposed in the opening 7 with the approximate center in the door width direction as a rotation fulcrum 14. As shown in FIG. The rotation fulcrum 14 is movable along the upper and lower rails 22 and 24.
In this embodiment, a runner 15 serving as a pivot fulcrum 14 is provided at the upper end of each door plate 11 so as to be rotatable with respect to the door plate 11, and a pivot 16 serving as a pivot fulcrum 14 is provided at the lower end of each door plate 11. An example is shown.

As shown in FIG. 3A, the runner 15 has a rolling portion and a rotation shaft that becomes a rotation fulcrum 14 that is rotatably connected to the rolling portion. A rolling portion of the runner 15 is engaged with and supported by an upper rail 22 provided on the upper frame 21, and can run along the longitudinal direction of the upper rail 22.
As shown in FIG. 3A, the pivot 16 has a substantially cylindrical shape, engages with a lower rail 24 provided on the lower frame 23, and is movable along the longitudinal direction of the lower rail 24. Yes.
The pivot fulcrum 14 of the door plate 11 is not limited to the one shown in the figure as long as it can rotate with respect to the rails 22 and 24 and can move along the rails 22 and 24. Various runner members, pivots, guide pieces and the like can be used. Moreover, it is good also as an aspect which provides only the runner 15 as the rotation fulcrum 14, without providing the lower rail 24 and the pivot 16 engaged with this. Further, the structure is not limited to the upper suspension type as shown in the figure, and may be a lower load type structure. In this case, a pivot, a guide piece or the like may be provided on the upper end side of the door plate 11, a runner member, a door wheel or the like may be provided on the lower end side of the door plate 11, and rails corresponding thereto may be provided vertically.

Moreover, in this embodiment, as shown in FIG.1 (b) and FIG.3 (b), the rotation fulcrum 14 of each doorplate 11 and the wall surface (indoor side wall surface) 5 by the side of the indoor space of the partition wall 4 and wall thickness. The upper and lower rails 22 and 24 are arranged so as to be substantially the same position in the direction. That is, the rails 22 and 24 are provided so that the upper and lower rails 22 and 24 and the left and right indoor side wall surfaces 5 of the opening 7 are located in substantially the same vertical surface area.
A handle 19 is provided at one end of the door plate 11 disposed on the center side in the width direction of the opening 7 of each folding door 10. The position where the handle 19 is provided and the shape of the handle 19 can be appropriately set according to the number of the door plates provided (odd or even).
As shown in FIGS. 1 and 3, the folding door 10 configured as described above is opened and closed (folded and unfolded) with a handle 19 or the like. At the time of opening and closing, the pivot fulcrum 14 of each door plate 11 of each folding door 10 moves along the rails 22 and 24 while rotating with respect to the rails 22 and 24 and is connected by the connecting member 18. The adjacent door plates 11 rotate about the connection side rotation fulcrum 17.

When the folding door 10 is unfolded and the opening 7 is closed as shown in FIG. 1A, the door plates 11 of the folding door 10 are arranged in a straight line. In the illustrated example, each door plate 11 is arranged in a straight line on the rails 22 and 24 so as to extend along the door width direction.
On the other hand, when the folding door 10 is folded and the opening 7 is opened as shown in FIGS. 1B and 3B, the door plates 11 of the folding door 10 are orthogonal to the longitudinal direction of the rails 22 and 24. It arrange | positions so that the door width direction may be along with the direction (wall thickness direction) to do. As described above, in this embodiment, the rotation fulcrum 14 at the center of the door width direction of each door plate 11 is moved along the rails 22 and 24. Therefore, when the folding door 10 is folded, both end portions 12 and 13 in the door width direction of the door plates 11 are in a state of protruding to the indoor space 2 side and the storage space 3 side with the rails 22 and 24 interposed therebetween. . That is, as shown in FIG. 3B, the indoor space side end portion 12 of each door plate 11 protrudes toward the indoor space 2 along the wall thickness direction from the rails 22 and 24, and the storage space side end portion 13 It will be in the state which protruded in the storage space 3 side along the wall thickness direction rather than each rail 22 and 24. FIG.

The projection size of each door plate 11 toward the indoor space 2 is smaller than a conventional folding door whose one side end in the door width direction is guided along the rail, whereas the projection toward the storage space 3 side. The dimensions tend to be large compared to such conventional folding doors. For this reason, it may be considered that the storage space 3 cannot be used efficiently.
Therefore, in the present embodiment, as shown in FIGS. 1B and 3B, the storage space side end 13 of each door plate 11 in the state in which the folding door 10 is folded is replaced with the storage space 3 of the partition wall 4. It is set as the structure located in the indoor space 2 side rather than the wall surface (storage side wall surface) 6 of the side. That is, the storage space side end 13 of each door plate 11 in a state in which the folding door 10 is folded is positioned closer to the indoor space 2 along the wall thickness direction than the vertical surface area connecting the left and right storage side wall surfaces 6 of the opening 7. It is supposed to be a structure.

In this embodiment, as shown in FIG.3 (b), the door width dimension W1 of the doorplate 11 of each folding door 10 is set so that it may become the said structure. The door width dimension W1 of the door plate 11 is the wall thickness direction from the pivot fulcrum 14 provided at the approximate center of the door width direction of each door plate 11 guided by the rails 22 and 24 to the storage side wall surface 6 as described above. It can be set according to the dimension W2 along. That is, it is only necessary to set so that a half of the door width dimension W1 is smaller than the dimension W2. Moreover, according to the opening width dimension (dimension between the prospective surfaces of the left and right vertical frames 25, 25) of the opening 7 so that the door width dimension W1 of each door panel 11 satisfies the above-described conditions, The number of sheets may be set to an appropriate number.
The general wall thickness dimension is, for example, about 70 mm to 250 mm, but the type of building structure (wooden frame structure, framed wall structure, steel structure, RC structure, etc.), and the partition wall 4 is a structural wall. Depending on whether it is a (bearing wall) or a partition wall, the dimensions are often standardized to some extent. Similarly, the opening width dimension of the opening 7 is often a standardized dimension to some extent. In such a case, according to these standardized wall thickness dimensions and opening width dimensions, the position along the wall thickness direction of the rotation fulcrum 14 (that is, the rails 22 and 24 provided in the opening frame 20). The position along the wall thickness direction), the door width dimension W1 and the number of door plates 11 can be set in advance. In this case, these can be manufactured in advance in a factory or the like as a folding door device provided with the folding door 10 and the opening frame 20 set as appropriate.

According to the storage opening / closing structure 1 according to the present embodiment having the above-described structure, the storage space 3 is efficiently used while reducing the projecting dimension of the folding door 10 toward the indoor space 2 when opening / closing and opening. can do.
That is, the storage space side end 13 of each door plate 11 in a state in which the folding door 10 is folded is configured to be positioned closer to the indoor space 2 than the storage side wall surface 6 of the partition wall 4. Therefore, when the folding door 10 is opened / closed and opened, the folding door 10 can be prevented from interfering with stored items, shelves and the like stored in the storage space 3, and the storage space 3 can be used efficiently. .
In addition, each door plate 11 of the folding door 10 can be rotated with respect to the rails 22 and 24 disposed in the opening 7 with the approximate center in the door width direction as a rotation fulcrum 14, and the rotation fulcrum 14 is set to the rail 22, 24. 24 is freely movable. Therefore, when folded, the dimension protruding toward the indoor space 2 with respect to the rails 22 and 24 can be made relatively small.
That is, according to the storage opening / closing structure 1 according to the present embodiment, while the storage space 3 can be used efficiently, the projecting dimension of the folding door 10 toward the indoor space 2 at the time of opening / closing and opening can be reduced. Can be small. Therefore, the folding door 10 can be opened smoothly, and the effective space of the indoor space 2 can be increased.

Moreover, in this embodiment, the folding door 10 is made into the structure which connected the door plates 11 with the connection member 18 so that each door plate 11 may be folded substantially parallel. Therefore, the effective width dimension of the opening 7 can be efficiently increased.
Furthermore, if the thickness dimension of each door plate 11 is made relatively thin as described above, the effective width dimension of the opening 7 can be increased more effectively.

  Moreover, in this embodiment, the rails 22 and 24 are arrange | positioned so that the rotation fulcrum 14 of each doorplate 11 may become the indoor side wall surface 5 of the partition wall 4 and the substantially same position in a wall thickness direction. Therefore, the door width dimension W1 of the door plate 11 can be made relatively large while the storage space 3 can be used efficiently, and the required number of door plates 11 can be made relatively small. In addition, if the arrangement position along the wall thickness direction of the rails 22 and 24 is on the side opposite to the storage space (front side) from the indoor side wall surface 5, the number of door plates 11 can be further reduced. The opening frame 20 and the folding door 10 in the folded state protrude relatively large from the indoor side wall surface 5 toward the front side. Therefore, the rails 22 and 24 are disposed so that the rails 22 and 24 are disposed substantially at the same position in the wall thickness direction with the indoor side wall surface 5 and located closer to the storage space 3 than the indoor side wall surface 5. Is preferred.

In the above-described example, an example in which two sets of folding doors 10 and 10 are arranged in the opening 7 is shown. However, a mode in which one set of folding doors 10 is arranged, or three or more folding doors 10 may be provided. It is good also as an aspect which arranges.
Moreover, in the above-mentioned example, although the folding door 10 provided with the four door boards 11 is illustrated, what is necessary is just to set it as the folding door 10 provided with the appropriate number of door boards 11 according to the above required number of sheets. Moreover, although two sets of folding doors 10 and 10 with the same number of door plates 11 are illustrated, folding doors having different numbers of door plates may be adopted. In the storage opening opening / closing structure 1 according to the present embodiment, the door width dimension W1 of the door plate 11 is relatively small and the number of the door plates 11 tends to be relatively large as compared with the conventional one. Therefore, by making the number of the door plates 11 of the two sets of folding doors 10 and 10 different, the summing position of the folding doors 10 and 10 can be adjusted in the width direction of the opening 7, and the degree of freedom of these summing positions is relatively large. Can be increased. As a result, it is possible to relatively increase the degree of freedom of the opening start position of each of the folding doors 10 and 10 (that is, the position along the width direction of the opening 7 of the door plate 11 having the handle 19).

Furthermore, although the example which made the ceiling side of the opening 7 to the middle of the partition wall 4 is shown in the example of a figure, it is good also as the opening 7 made into the height dimension to a substantially ceiling. In this case, you may make it arrange | position so that the upper frame 21 provided with the upper rail 22 may be embedded in a ceiling.
Furthermore, in the example of the figure, the prospective dimension of the opening frame 20 is made smaller than the wall thickness dimension of the partition wall 4, and an example in which the dust part is formed only on the indoor space 2 side is illustrated. You may make it employ | adopt the opening frame in which a dust part is formed also in the storage space 3 side. In this case, you may make it grasp | ascertain the finding surface by the side of the storage space of this opening frame as a wall surface by the side of the storage space. Moreover, you may make it employ | adopt the opening frame 20 in which such a Chile part is not formed.
In the above-described example, the folding door 10 is illustrated as being foldable until the door plate 11 of the folding door 10 is in a substantially parallel state in the open state, but a folding door that is not in a substantially parallel state in the open state is employed. You may do it.
