Description

  The present invention relates to a folding door, a window with a folding door, which is attached to a window frame or a shutter of a house or a building, is attached as a door of furniture having a door, or covers and hides a corner of an indoor space. Is.

  In addition to curtains and blinds, sliding doors that can be opened and closed are often attached to windows and shutters of houses and buildings. In particular, if the room with windows and shutters is a Japanese style room, or a room with profound or high-class feeling, paper shoji (paper shoji or wood shoji) may be installed. There is. In addition, not only window frames but also sliding doors and hinged doors that cover the entire wall surface of a room may be installed. This is because by providing a sliding door or hinged door that covers the entire wall surface, the entire wall surface with windows is closed and opened, improving the aesthetics of the entire room and achieving both a sense of openness and privacy. . Alternatively, the storage space can be easily formed in a part of the room by closing and opening the entire wall surface without windows.

  By the way, since such a shoji and a hinged door are opened and closed by a slide type, there exists a problem which cannot open a window or some indoors completely. If it cannot be fully opened, not only does the daylighting of the room weaken, but there is also a problem that the feeling of openness of the room weakens. For this reason, the folding door which covers a window frame and a wall surface may be employ | adopted.

  However, the folding door can bring the door plate to the end on the side of the suspension, but the bent door plate protrudes toward the room as it is. For this reason, the technique which further folds the door_plate | bend bend | folded to the handle side is proposed (for example, refer patent document 1 and patent document 2). These techniques are used to fold the moved door panel by folding it into the first guide groove that is necessary to move the door panel in order to fold the folded door panel. The second guide groove is used.

  Patent document 1 is provided with a folding door shoji on the side of the hanging hand and an open end folding door shoji connected to the folding door shoji. The folding door by which the folding door shoji is folded by the movement of the guide member with respect to the guided groove is disclosed. Here, as described in FIG. 8b of Patent Document 1, the guide groove has a curved guide groove bent from the refracting portion following the straight guide groove. When the guide member provided in the folding door shoji reaches the refracting portion that is the boundary between the linear guide groove and the curved guide groove, the guide member enters the curved guide groove. When the guide member enters the curved guide groove, the folding door shoji comes out before the lower frame, and is folded until the folding door shoji becomes substantially parallel to the lower frame.

  On the other hand, Patent Document 2 has an object of preventing the curved guide groove used in Patent Document 1 from greatly protruding into the room and deteriorating its appearance.

  Patent Document 2 discloses a folding door in which an arm is attached to a moving folding door, and the attached arm is provided with two guide members, and the two guide members move along different guide grooves. The two guide grooves have respective grooves on the indoor side and the window side. The groove on the window side has a refracting portion on the hanging side, and the groove after refracting escapes the guide member to the window side. . As a result, when the folding door is bent, the arm is perpendicular to the frame, and the folding door is folded substantially parallel to the frame.

Thus, all the folding doors in the prior art have a groove connected to the linear guide groove via the refracting portion, so that the door plate is folded and folded.
Japanese Utility Model No. 2-8070 Japanese Patent No. 2575328

  However, when the folding door is not completely folded, there is a problem that a feeling of pressure in the room is generated if the doorboard remains in the front, regardless of whether the folding door is installed on the window frame or the wall surface. is there. On the other hand, the conventional technique for folding folding doors has the following problems.

  In the folding door disclosed in Patent Document 1 and the folding door disclosed in Patent Document 2, the guide groove for moving the moving door plate has a refracting portion in the middle. The guide groove to the refracting portion is used to open the moving door plate, and the guide groove from the refracting portion is used to fold the moving door plate and the door plate on the suspension side.

  When the guide groove has a refracting portion as described above, there is a problem that the movement of the guide member is often not smooth. This is because the guide member that moves the door plate is caught by the refracting portion. In particular, as time passes after the door plate is installed, the sliding of the guide groove and the guide member becomes worse, and therefore the movement of the guide member in the refracting portion tends to become worse. As described above, since the movement of the guide member in the guide groove is not smooth, there is a problem that the user needs to move the door plate with a strong force and the load is large. Since the movement of the guide member has deteriorated, there is also a problem that the folding door is damaged when the user moves the door plate with a strong force.

  Further, as is clear from the drawings disclosed in Patent Documents 1 and 2, in the case of a structure in which the door plate is folded using the refracting portion of the groove, the width of the door plate on the suspension side and the door plate on the moving side are made different. There is a need. For this reason, there is a problem that it looks bad, and there is a problem that the cost in the manufacturing process becomes high. This is a structure in which the door plate is folded by moving the guide groove bent from the refracting part after moving the linear guide groove partway, so the width of the door plate on the suspension side and the moving side is reduced. It is necessary to make them different.

  In addition, even if the door plate is folded, the width of the door plate is different, so that the base of the door plate remains in the window, and the window cannot be completely opened. In patent document 1, in order to move the curvilinear groove after the refracting portion, the moving side door plate remains in the window frame. In Patent Document 2, a groove is formed inside the horizontal frame, and the moving door plate is moved using an arm, so that the moving door plate remains in the window frame inside the horizontal frame. In both Patent Documents 1 and 2, there is a problem that even if the door panel is folded, a part of the door panel remains inside the window frame and the entire window frame cannot be opened.

  Moreover, since the folding door of patent document 2 requires an arm, it also has the problem that a movement tends to worsen over time. Since there are two joint portions between the joint portion of the arm and the guide member, the joint portion of the arm and the door plate, and the door plate to the guide groove, there are many causes that make it difficult to operate or break down. In addition, there is a problem that it becomes difficult to move the door plate due to the deterioration of the arm. In particular, various folding doors using arms have been proposed, but the two parts of the door plate and arm connection part, and the arm and frame connection part in opening and closing the folding door are the mechanism part of the operation, so that only Easy to operate. Of course, failure and deterioration are likely to occur as the number of mechanism parts increases. Moreover, even if the door plate is moved and folded, the arm portion remains in the opened opening, so that there is a problem that visibility and scenery are poor and lack of feeling of opening.

  In addition, when the folding doors of Patent Documents 1 and 2 are installed on the wall surface, the opening is not completely opened, and not only the feeling of opening is bad, but also the luggage is taken in and out of the storage space inside the folding door. There is also a problem that causes trouble.

  In view of the above-mentioned problems, the present invention is a folding door that can smoothly move and fold a door plate over a long period of use and can be completely opened to a window frame and a wall surface corresponding to a folding door portion with little failure and deterioration. The purpose is to provide windows with folding doors.

  In order to solve the above-described problems, the folding door of the present invention includes a suspension door plate, one end of which is pivotally supported by a support member at a predetermined pivot support position, and a folding door plate folded at a connection position at one end opposite to the pivot support position. The movable door plate that can be connected, the horizontal frame having a guide groove that guides the movement of the movable door plate, the hanging door plate and the movable door plate are rotatable, and moved with the suspended folding door plate that is rotated and folded. The movable door plate has a guide that is slidably fitted to the guide groove, and the movable door plate is movable by moving the guide groove in the guide groove. The guide groove has a predetermined start point and a predetermined end point, and is formed obliquely and without refraction from the start point to the end point.

  According to the present invention, the door plate can be smoothly moved and folded during opening and closing. Moreover, even if the usage period is long, there is little deterioration and failure. Even a weak woman, child, or elderly person can easily open and close the doorboard.

  Moreover, since the width | variety of a hanging door board and a movable door board can be made the same, manufacturing cost can also be held down.

  In addition, since the movable door plate can be moved to the storage area and folded, the door plate does not remain in the opening surrounded by the support member and the horizontal frame, and the feeling of opening is enhanced. Of course, when the interior of the folding door is a storage space, it is easier to go to and from the storage space and to put in and out the luggage.

  As a result of the above, it is possible to provide a folding door and a window with a folding door that are excellent in durability and easy to use and enhance the feeling of opening in the room, and also provide a comfortable living space.

  In the present specification, the suspended door plate and the movable door plate may be collectively referred to as a door plate.

  The folding door according to the first aspect of the present invention can be folded with the suspension door plate at one end pivotally supported by the support member at a predetermined pivot support position and at the connection position at one end opposite to the pivot support position. The movable door plate to be connected, the horizontal frame having a guide groove for guiding the movement of the movable door plate, the suspension door plate and the movable door plate are rotatable, and the suspended door plate and the movable door plate that are rotated and folded. The movable door plate has a guide slidably fitted to the guide groove, and the movable door plate is movable by moving the guide groove in the guide groove. The groove has a predetermined start point and a predetermined end point, and is formed obliquely and without refraction from the start point to the end point.

  With this configuration, the door plate moves smoothly without being caught or clogged. Even if the period of use becomes longer, the movement of the doorboard is less likely to be difficult.

  In the folding door according to the second invention of the present invention, in addition to the first invention, the guide groove has a predetermined start point and an end point, and the starting point is the position of the guide when the suspension door plate and the movable door plate are extended. The pivot point side is the end point, and the start point is located on the first direction side for the thickness from the front of the movable door plate to the guide, with respect to the virtual straight line where the pivot point position is substantially parallel to the horizontal frame. The end point is located on the second direction side opposite to the first direction side by the thickness obtained by adding the thickness from the back surface of the movable door plate to the guide to the thickness of the suspension door plate with respect to the virtual straight line.

  With this configuration, when both the suspended door plate and the movable door plate are moved and folded, neither the suspended door plate nor the movable door plate remains in the opening. Further, the suspension door plate and the movable door plate are folded up to a state where the end portions thereof do not protrude from the horizontal frame. That is, it is stored so as to overlap the support member. For this reason, the opening is completely opened.

  In the folding door according to the third invention of the present invention, in addition to any of the first to second inventions, when the guide slides to the vicinity of the end point, the suspension door plate and the movable door plate are pivotally supported. The guide is slidable in the guide groove up to a position where the suspension door plate and the movable door plate can be accommodated in the storage area so as to be substantially parallel to the horizontal frame.

  With this configuration, the door plate is folded to a position substantially parallel to the horizontal frame. In addition, the position where the guide is provided at the tip of the movable door plate is folded based on the pivotal support position of the hanging door plate, so that the door plate is completely removed from the opening. In particular, the suspension door plate and the movable door plate are stored so as to overlap the support member.

  In the folding door according to the fourth aspect of the present invention, in addition to any one of the first to third aspects, the width of the suspension door plate and the movable door plate corresponding to the horizontal frame is substantially the same.

  With this configuration, the door plate is folded substantially parallel to the horizontal frame. As a matter of course, the moving door plate does not leave a part of the opening, not to mention the hanging door plate.

In the folding door according to the fifth aspect of the present invention, in addition to any of the first to fourth aspects, the width corresponding to the horizontal frame of the storage area is larger than the width of each of the suspension door plate and the movable door plate. In the folding door according to the sixth aspect of the present invention, in addition to any of the first to fifth aspects, the storage area is formed on the front surface or the back surface of the support member.

  With these configurations, the folded doorboard overlaps with the support member and is stored, so that a clean appearance is produced.

  In the folding door according to the seventh invention of the present invention, in addition to any of the first to sixth inventions, at least a part of the horizontal frame and the support member is a part of the wall material on which the folding door is installed. is there.

  With this configuration, the appearance of the folding door and its peripheral members in the room is clean. Also, strength is ensured.

  In the present specification, the door is a member provided on the indoor side of a window or a shutter made of various materials such as wood, resin, metal, paper, synthetic wood, and leather.

(Embodiment 1)
(Overview)
First, an overview of the folding door will be described with reference to FIG.

  FIG. 1 is a perspective view of a folding door according to Embodiment 1 of the present invention. Since FIG. 1 is a perspective view seen from an oblique direction, elements provided inside the frame cannot be visually recognized in FIG. However, it will become clear in the other figures and their description.

  The folding door 1 is provided with a support member 2 (not necessarily vertical, as long as it intersects the floor surface) that is erected substantially perpendicular to the floor surface. One end is pivotally supported at the pivot position 11. The movable door plate 6 is connected to the suspension door plate 5 in the lateral direction at the connection position 12. The movable door plate 6 is connected to the suspension door plate 5 so as to be bendable.

  Further, the folding door 1 includes a horizontal frame 4 positioned above the support member 2, the hanging door plate 5 and the movable door plate 6. The horizontal frame 4 may be connected to the support member 2 or may be physically separated from the support member 2 and then connected to a wall or a ceiling. Alternatively, the horizontal frame 4 may be formed as a part of the ceiling. The horizontal frame 4 includes a guide groove 8 that guides the movement of the movable door plate 6.

  The suspension door plate 5 and the movable door plate 6 are rotatable, and the suspension door plate 5 and the movable door plate 6 that are turned and folded are accommodated in a storage area 3 formed on the surface of the support member 2. The The movable door plate 6 has a guide 7 that is slidably fitted to the guide groove 8, and the movable door plate 6 can move as the guide 7 moves through the guide groove 8. The guide groove 8 has a start point 9 and an end point 10, and the guide groove 8 is formed from the start point 9 to the end point 10 obliquely and without being refracted. Here, “not refracted” means that the guide groove 8 does not have a bent portion from the start point 9 to the end point 10.

  The space covered by the hanging door plate 5 and the moving door plate 6 becomes the opening 21 that is opened when the hanging door plate 5 and the moving door plate 6 are stored in the storage area 3. A window frame or a storage shelf is provided over the opening 21. When the suspension door plate 5 and the movable door plate 6 are stored in the storage region 3, the window frame and the storage shelf are opened. When the folding door 1 is closed, the interior of the folding door 1 is closed with respect to the room by the support member 2 and the door board (the hanging door board 5 and the movable door board 6). On the other hand, when the folding door 1 is opened, the opening 21 is opened, and the interior of the folding door 1 can be passed through the opening 21. When a window frame is provided on the inner wall of the folding door 1, the field of view corresponding to the opening 21 is open to the window frame. Or when the storage shelf is provided in the inside of the folding door 1, the utilization of a storage shelf is attained by opening the folding door 1. FIG.

  That is, the folding door 1 has a function of opening the opening 21 connected to a window frame, a storage shelf, or the like, or closing the opening 21. At this time, the folding door 1 realizes closing and opening of the opening 21 facing the window by the moving operation of the suspension door plate 5 and the movable door plate 6.

  The opening 21 is closed by the hanging door plate 5 and the movable door plate 6. That is, the opening 21 is closed when the hanging door plate 5 and the movable door plate 6 are extended. The opening 21 is gradually opened by the movement of the movable door plate 6 according to the guide groove 8. Since the opening 21 is closed, the window frame and the storage shelf at the position corresponding to the opening become invisible. When the opening 21 is opened, the window frame and the storage shelf are visible from the room and opened.

  Next, the outline | summary of the opening / closing operation | movement of the folding door 1 is demonstrated using FIGS.

(Overview of operation)
The movable door plate 6 moves in position when the guide 7 slides in the guide groove 8. Here, since the movable door plate 6 is connected to the suspension door plate 5 so as to be bent at the connection position 12, when the movable door plate 6 moves according to the guide groove 8, the connection position 12 protrudes to the indoor side. The hanging door plate 5 also approaches the pivot support position 11 side in accordance with this protrusion. As the position of the movable door plate 6 approaches the pivot support position 11, the suspension door plate 5 also approaches the pivot support position 11, and opening of the opening 21 proceeds. Furthermore, when the movement of the movable door plate 6 proceeds, the suspended door plate 5 and the movable door plate 6 are rotated together, and the suspended door plate 5 and the movable door plate 6 are folded. Eventually, the opening 21 is opened and the doorboard is folded into the storage area 3 without protruding to the indoor side. Since the suspended door board 5 and the movable door board 6 are rotated and folded in the storage area 3, the door board does not protrude on the indoor side. In addition, all the openings 21 that are regions where the support member 2 remains are opened. For this reason, since the suspension door board 5 and the movable door board 6 overlap with the support member 2 and are folded in the storage area 3, there is no unpleasant projection of the door board indoors, and a part of the door board is in the opening 21. It will not remain. The folded exterior door plate 5 and the movable door plate 6 overlap the support member 2, so that the appearance in the room is clean.

  FIG. 2 is a perspective view of the folding door according to Embodiment 1 of the present invention. FIG. 2 shows a state in which the closed doorboard shown in FIG. 1 is slightly opened. The movable door plate 6 has, for example, a door knob, and the user can move the movable door plate 6 by pulling the door knob. When the door knob is pulled, the guide 7 provided on the movable door plate 6 slides in the guide groove 8 and the position of the movable door plate 6 changes. At this time, the movable door plate 6 moves while protruding toward the indoor side. The suspended door plate 5 connected to the movable door plate 6 so as to be foldable at the connection position 12 starts to protrude to the indoor side by drawing a substantially square shape so as to be pushed out by the movable door plate 6.

  At this time, since the guide element 7 slides in the guide groove 8 which is oblique and has no refraction, the guide element 7 does not get caught or become difficult to move in the guide groove 8. The guide 7 moves smoothly in the guide groove 8. That is, the movable door plate 6 also moves smoothly.

  When the movement of the movable door plate 6 further proceeds, as shown in FIG. 3, the movable door plate 6 and the suspended door plate 5 are completely combined and moved to the support member 2 having the pivot position 11. FIG. 3 is a perspective view of the folding door according to Embodiment 1 of the present invention. FIG. 3 shows a state in which the movable door plate 6 and the suspended door plate 5 are completely combined and approach the pivotal support position 11.

  When the movable door plate 6 and the suspended door plate 5 move to the state shown in FIG. 3, the opening 21 is opened. However, in the state of FIG. 3, since the movable door plate 6 and the suspended door plate 5 that have moved to the support member 2 remain protruding toward the indoor side, the feeling of opening in the room is still insufficient.

  The movable door plate 6 and the suspended door plate 5 that have moved to the support member 2 and joined to each other can be rotated about the pivotal support position 11 (that is, the end point 10 of the guide groove 8). The guide groove 8 has an end point 10 so that the movable door plate 6 and the suspended door plate 5 can be rotated to a position substantially parallel to the horizontal frame 4. For this reason, as shown in FIG. 4, the movable door plate 6 and the suspended door plate 5 are folded to a position substantially parallel to the horizontal frame 4.

  FIG. 4 is a perspective view of the folding door according to Embodiment 1 of the present invention. FIG. 4 shows a state in which the movable door plate 6 and the suspension door plate 5 are rotated and folded to a position substantially parallel to the horizontal frame 4.

  Since the guide groove 8 extends to a position exceeding the position of the support member 2 in the horizontal frame 4, the movable door plate 6 and the suspended door plate 5 which are combined with each other as shown in FIG. That is, the guide element 7 can move not only to the position where the movable door plate 6 and the suspension door plate 5 meet each other as shown in FIG. Due to the movement of the guide 7, the movable door plate 6 rotates so as to push the suspension door plate 5. This is because the suspension door plate 5 is pivotally supported at the pivot support position 11, so that the suspension door plate 5 rotates around the pivot support position 11 by the force pushed from the movable door plate 6. Since the movable door plate 6 is aligned with the suspension door plate 5, the movable door plate 6 is also rotated based on the pivot position 11 in accordance with the rotation of the suspension door plate 5.

  In this way, the moving door plate 6 and the suspension door plate 5 rotate around the pivot support position 11 as the guide 7 moves through the guide groove 8 extending obliquely to a position beyond the support member 2. As a result of the rotation, as shown in FIG. 4, the movable door plate 6 and the suspension door plate 5 are folded so as to be substantially parallel to the horizontal frame 4. At this time, the suspension door plate 5 and the movable door plate 6 are folded into the storage area 3 provided on the surface of the support member 2. Since the horizontal width of the support member 2 is larger than the horizontal width of each of the suspension door plate 5 and the movable door plate 6, the suspension door plate 5 and the movable door plate 6 overlap the surface of the support member 2 as they are. For this reason, the folded suspension door board 5 and the movable door board 6 will be in the state which overlapped with the supporting member 2 completely, when it sees from the indoor side, and it is very refreshing also on an external appearance. Furthermore, the door board does not protrude in the room, and the feeling of opening in the room increases together with the feeling of opening of the opening 21.

  Here, the guide groove 8 in the first embodiment is formed from the start point 9 to the end point 10 obliquely and without being refracted. For this reason, the guide 7 that slides in engagement with the guide groove 8 does not need to go through the refracting portion, and thus operates smoothly. As a result, unlike the conventional folding door, the moving door plate 6 moves smoothly, and the moving operation does not become difficult as the usage period elapses. Moreover, even if it is a weak child, a woman, and an elderly person, the movable door board 6 can be moved without difficulty.

  In particular, in the folding door of the prior art, the user needs to pass through the refracting part of the guide groove when turning the moved movable door plate and the suspended door plate. Since the refracting portion is routed, the guide groove and the guide are damaged, and the difficulty of the moving operation increases with the lapse of the use period.

  On the other hand, in the folding door 1 of Embodiment 1, since the guide groove 8 does not have a refracting part, the guide element 7 is hardly caught or stopped in the guide groove 8. For this reason, the movement operation of the guide element 7 in the guide groove 8 is very smooth, and the operation of the guide element 7 in the guide groove 8 is less likely to deteriorate with the passage of the use period.

  Thus, the folding door 1 of Embodiment 1 has the merit that the door plate can be opened and closed smoothly, and malfunctions that tend to occur over time can be reduced.

  Next, the detail of each part is demonstrated.

(Support member)
The folding door 1 is connected to the support member 2. The support member 2 pivotally supports one end of the hanging door plate 5 at the pivotal support position 11. The shaft support is realized by a hinge or the like. The pivot support position 11 corresponds to a position where the support member 2 and the hanging door plate 5 are in contact with each other. In particular, the pivot support position 11 is a position where the support member 2 and the hanging door plate 5 are in contact with each other, and is suitably on the surface side (inside the room) of the support member 2. This is because the suspension door plate 5 and the movable door plate 6 are folded around the pivot support position 11 by providing the pivot support position 11 on the indoor side. Of course, the pivot support position 11 may be provided in the middle of the support member 2. For example, if the hanging door plate 5 is folded on the front surface of the support member 2 by a component such as a concealed hinge, the pivot support position 11 is located not on the front surface of the support member 2 but on the inside. May be.

  The support member 2 forms a storage area 3 of a door plate (a hanging door plate 5 and a movable door plate 6) that is folded next to the door plate 1 at a position that partitions a certain indoor space. The support member 2 may be formed of an independent plate material like the hanging door plate 5 and the movable door plate 6 or may be formed of a plate material protruding from the wall. Of course, the support member 2 may be formed as a part of the wall. The support member 2 may be a component of the folding door 1 or an external element, and the folding door 1 may be distributed in a state including the support member 2, or the support member You may distribute | circulate in the state which does not contain 2.

  The support member 2 may be formed of various materials such as wood, metal, resin, synthetic wood, paper material, leather material, and the surface may be subjected to a treatment such as a pattern or color. The support member 2 is configured to intersect the floor surface, and is generally configured substantially perpendicular to the floor surface. The opening 21 is formed together with the horizontal frame 4. For this reason, when a window frame is provided inside the folding door 1, the support member 2 may be adjusted to a position along the end of the window frame.

  In addition, it is preferable that the supporting member 2 is the same material, color, and surface treatment as the hanging door plate 5 and the movable door plate 6. This is because when the folding door 1 is closed, all of the support member 2, the suspension door plate 5, and the movable door plate 6 are integrated and can be viewed from the indoor side. Naturally, a clean appearance can be obtained by integrating the support member 2, the suspension door plate 5, and the movable door plate 6 together.

  Moreover, since the supporting member 2 forms the storage area | region 3 which accommodates the folded folding door board 5 and the movable door board 6 in the surface or back surface, the horizontal width of the supporting member 2 is the hanging door board 5 and the movable door board 6. It is preferable that the width is equal to or greater than the lateral width, more preferably substantially the same. Since the horizontal width of the support member 2 is substantially the same as the horizontal width of the suspension door plate 5 and the movable door plate 6, the suspension door plate 5 and the movable door plate 6 accommodated in the storage region 3 are attached to the surface of the support member 2 (this region is This is because, in the storage area 3), it completely overlaps with the support member 2 to produce a clean appearance.

(Storage area)
The storage area 3 is a space that is formed on the front surface or the back surface of the support member 2 and stores the folded hanging door plate 5 and movable door plate 6. When the suspension door plate 5 and the movable door plate 6 are folded on the front side of the support member 2, the storage area 3 is formed on the surface of the support member 2, and the suspension door plate 5 and the movable door plate 6 are on the back side of the support member 2. The storage area 3 is formed on the back surface of the support member 2 in the case of being folded.

  The storage area 3 is a space in which the folded suspension door board 5 and the movable door board 6 are stored on the front surface or the back surface of the support member 2 and is not a space where the area can be divided in appearance. The storage region 3 has an area corresponding to the area of the support member 2.

  When the folding door plate 5 and the movable door plate 6 are folded with the pivotal support position 11 as a base point and folded, they overlap with the support member 2 as they are. Due to this overlap, the folded suspension door plate 5 and the movable door plate 6 are completely integrated with the support member 2 when the folding door 1 is viewed from the front, and a clean appearance is produced.

  When the hanging door plate 5 and the movable door plate 6 are folded on the back surface of the support member 2 with the pivot support position 11 as a base point, the storage region 3 is formed on the back surface of the support member 2.

  As described above, the storage area 3 is formed on the front surface or the back surface of the support member 2, and the folded hanging door panel 5 and the movable door panel 6 are stored so as to be neatly accommodated in the storage area 3.

(Horizontal frame)
The horizontal frame 4 guides the movement of the movable door panel 6. The horizontal frame 4 may be connected to the support member 2, may be formed as a part of the ceiling or wall, and may be separated from the support member 2. The horizontal frame 4 forms the opening 21 together with the support member 2. The opening 21 is shielded by the hanging door plate 5 and the movable door plate 6. In addition to the suspension door plate 5 and the movable door plate 6, when an intermediate plate or the like is provided, or when there are a plurality of suspension door plates and movable door plates, the opening 21 is shielded by these.

  The interior space of the folding door 1 may be provided with a storage space or a window frame. However, since the window frame is preferably completely opened through the opening 21, the window frame corresponds to the opening 21. It is preferable to be provided in the area to be used. Further, the shape of the opening 21 (that is, the shape determined by the shapes of the hanging door plate 5 and the movable door plate 6) may be determined depending on how the window frame and the internal space are used.

  Further, the horizontal frame 4 has a guide groove 8 serving as a reference for moving the movable door plate 6. When the horizontal frame 4 is provided on the upper portion of the support member 2 (that is, the ceiling side in the room), the suspension door plate 5 and the movable door plate 6 move below the horizontal frame 4, so that the guide groove 8 It is formed on the lower surface of the frame 4. On the contrary, when the horizontal frame 4 is provided in the lower part of the support member 2 (that is, the floor side in the room), the suspension door plate 5 and the movable door plate 6 move on the horizontal frame 4, so the guide groove 8. Is formed on the upper surface of the horizontal frame 4.

  Similar to the support member 2, the horizontal frame 4 may be formed of various materials such as wood, metal, resin, synthetic wood, paper material, leather material, and the surface is subjected to processing such as pattern and color. Also good. Further, the horizontal frame 4 may have the same material or the same pattern as the support member 2 or may have a different material or pattern.

(Suspended and moving door panels)
The hanging door plate 5 is a door plate that is pivotally supported by the support member 2 at the pivotal support position 11 among the door plates that open and close the opening 21. For this reason, the suspension door plate 5 does not move at the pivot support position 11, and the position opposite to the pivot support position 11 of the suspension door plate 5 moves with the movement of the movable door plate 6. Since the suspension door plate 5 is pivotally supported at the pivot support position 11, the suspension door plate 5 and the movable door plate 6 move and rotate with reference to the pivot support position 11. The hanging door plate 5 and the movable door plate 6 are connected by a hinge at the connection position 12. Of course, the suspension door board 5 and the movable door board 6 should just be connected by the component which connects two members so that it can be bent other than a hinge.

  The suspended door board 5 and the movable door board 6 may be formed of various materials such as wood, metal, resin, synthetic wood, paper material, leather material, and the surface is subjected to processing such as patterns and colors. Also good. Further, the support member 2 and the horizontal frame 4 may have the same material or the same pattern, or may have a different material or pattern.

  However, it is preferable that the support member 2, the lateral frame 4, the hanging door plate 5, and the movable door plate 6 have the same material and the same color because of the appearance.

  Moreover, the suspension door board 5 and the movable door board 6 may be one each, and at least one may be plural. Further, an intermediate door plate may be provided between the hanging door plate 5 and the movable door plate 6. When at least one of the suspended door plate 5 and the movable door plate 6 is plural or an intermediate door plate is provided, the entire door plate is opened and closed in a form like a folding screen.

  It should be noted that it is appropriate that the hanging door plate 5 and the movable door plate 6 can completely close the opening 21, but there are differences in the shape and area of the opening 21 depending on the convenience of the design and the interior of the room. Also good.

(Movement of guide groove and door plate)
Next, details of the operation in the guide groove 8 will be described with reference to FIGS.

  FIG. 5 is an explanatory diagram showing a movement operation in the guide groove according to the first embodiment of the present invention. FIG. 5 shows a drawing in which the guide groove 8 and the door plate are seen through from above. The folding door shown in FIG. 5 shows a case where the suspension door plate 5 and the movable door plate 6 are folded on the surface of the support member 2. FIG. 5 shows in time series the state in which the door plate moves in accordance with the guide groove 8 in the order of (a) to (e).

  The guide groove 8 is formed in the horizontal frame 4 without being inclined and refracted. Here, the diagonal means that when the horizontal frame 4 is a virtual straight line, the horizontal frame 4 has a direction intersecting with the virtual straight line, and the virtual formed when the hanging door plate 5 and the movable door plate 6 are extended. It also has a direction that intersects with a straight line. In any case, the guide groove 8 is inclined so as to intersect with an imaginary straight line formed when the hanging door plate 5 and the movable door plate 6 are extended. Further, since the guide groove 8 does not have a refracting portion, the guide 7 fitted to the guide groove 8 can move linearly and is not caught during the movement. The moving door plate 6 is moved by the movement of the guide 7 that slides in the guide groove 8, and the hanging door plate 5 is moved along with the movement of the moving door plate 6.

  The guide groove 8 has a start point 9 and an end point 10, and the guide groove 8 is formed from the start point 9 to the end point 10 obliquely and without being refracted.

  In addition, when the number of the suspension door plates 5 and the movable door plates 6 is increased and the horizontal frame 4 is provided with a plurality of guide grooves 8, a plurality of guide grooves 8 are connected to each other so that a refracting portion may be generated. This is not a refraction part in the section from the start point 9 to the end point 10. For example, the two guide grooves 8 are connected to each other at their starting points 9, and this connection portion generates a refracting portion. In this case, the refracting portion is generated at the portion where the starting points 9 are connected to each other, which is different from the element of the present invention, which is diagonal from the starting point 9 to the ending point 10 and has no refracting portion.

  Next, the movement and folding of the doorboard according to the guide groove 8 will be described.

  First, FIG. 5A shows a state in which the suspension door plate 5 and the movable door plate 6 are extended and the opening 21 is closed. The suspension door plate 5 is pivotally supported by the support member 2 at the pivot support position 11. Here, the pivot support position 11 is provided on the surface (that is, the indoor side) of the support member 2. In addition, it is not essential for the pivot support position 11 to be located on the front surface or the back surface of the support member 2, and it may be located at a location inside the support member 2. As long as the hanging door plate 5 is folded on at least one front surface of the support member 2, the pivot support position 11 may be any position.

  The movable door plate 6 is connected to the suspension door plate 5 at the connection position 12, and the movable door plate 6 can be bent with respect to the suspension door plate 5 based on the connection position 12. The movable door plate 6 has a guide 7 that fits into the guide groove 8 at its tip.

  The guide groove 8 has a start point 9 and an end point 10, and the guide point 7 in a state where the suspension door plate 5 and the movable door plate 6 are extended (that is, the opening 21 is closed). The end point 10 exists at a position beyond the support member 2. Since the guide groove 8 is provided up to a position beyond the support member 2, the guide 7 can move beyond the support member 2. In other words, the starting point 9 is a location where the guide 7 included in the moving door plate 6 comes into contact with the guide groove 8 when the hanging door plate 5 and the moving door plate 6 are extended (when the opening 21 is closed). When the hanging door plate 5 and the movable door plate 6 are folded, the guide 7 is in contact.

  When the movable door plate 6 is slightly moved from the state shown in FIG. 5A, the state shown in FIG. 5B is obtained.

  FIG.5 (b) has shown the state in which the guide 7 moved a little.

  The guide 7 moves by sliding in the guide groove 8. As shown in FIG. 5B, when the guide 7 moves in the guide groove 8, the movable door plate 6 also moves. When the movable door plate 6 moves, the movable door plate 6 pushes out the suspended door plate 5 while bending around the connection portion 12. As a result, the hanging door plate 5 and the movable door plate 6 are bent while protruding in a substantially “<” shape on the indoor side. The opening 21 is opened little by little. As the guide 7 moves, the state changes to the state shown in FIG.

  FIG. 5C shows a state in which the guide 7 is moved and most of the opening 21 is opened.

  As the guide 7 moves, the moving door plate 6 also moves, and the hanging door plate 5 and the moving door plate 6 protrude further to the indoor side. In addition, opening of the opening 21 proceeds. The guide 7 proceeds in the oblique guide groove 8 as it is. When the guide 7 further moves, the state changes to the state shown in FIG.

  FIG. 5 (d) shows a state where the movable door plate 6 is brought into contact with the hanging door plate 5.

  As the movement of the movable door plate 6 proceeds, the movable door plate 6 approaches and touches the suspended door plate 5. At this time, the guide groove 8 still leaves room for the guide 7 to move. Since the guide groove 8 leaves room for the guide 7 to move, the guide 7 can further move along the guide groove 8. At this time, the guide groove 8 does not have a refracting part or a bent part (does not have a part that bends by a corner part) and extends obliquely, so that the guide 7 is caught by the refracting part or the bent part. You can move without stopping. In other words, the user can smoothly move the door plate from the state of FIG. 5D to the state of FIG.

  FIG. 5 (e) shows a state in which the hanging door plate 5 and the movable door plate 6 are rotated and pivoted about the pivot support position 11. The suspended door plate 5 and the movable door plate 6 are folded until they are substantially parallel to the horizontal frame 4 while being fitted to each other. That is, the hanging door board 5 and the movable door board 6 are stored in the storage area 3 by being folded until they are substantially parallel to the horizontal frame 4.

  Next, the positional relationship between the start point 9 and the end point 10 of the guide groove 8 will be described with reference to FIG. FIG. 6 is an explanatory diagram of the guide groove in the first embodiment of the present invention. FIG. 6 shows a straight line formed by the shaft support position 11 substantially parallel to the horizontal frame 4 as a virtual straight line 30.

  The starting point 9 of the guide groove 8 is located on the first direction side with respect to the virtual straight line 30 by the thickness from the front surface of the movable door plate 6 to the guide 7. This thickness is the thickness α shown in FIG.

  On the other hand, the end point 10 of the guide groove 8 is located on the second direction side with respect to the virtual straight line 30 by the thickness obtained by adding the thickness from the back surface of the movable door plate 6 to the guide 7 to the thickness of the suspension door plate 5. This thickness is the thickness β shown in FIG.

  When the suspension door plate 5 and the movable door plate 6 are folded on the surface of the support member 2, the first direction side is the back side of the folding door (that is, the internal space side), and the second direction side is the folding door. It is the front side (that is, the indoor side). On the other hand, when the hanging door plate 5 and the movable door plate 6 are folded on the back surface of the support member 2, the first direction side is the front side (inside the indoor space) of the folding door, and the second direction side is the folding door. It is the back side (namely, internal space side).

  The guide 7 is movable to the end point 10 of the guide groove 8. The end point 10 of the guide groove 8 is present at a position moved to the second direction side by the thickness β with respect to the virtual straight line 30. That is, it is located on the second direction side of the virtual straight line 30 by the thickness β. Here, the thickness β is determined by the length obtained by adding the thickness from the back surface of the movable door plate 6 to the guide 7 to the thickness of the hanging door plate 5. When the suspended door plate 5 and the movable door plate 6 are folded, the guide 7 should be positioned on the second direction side with respect to the virtual straight line 30 by the thickness β. Since the guide groove 8 has a start point 9 and an end point 10 at positions necessary for the movement of the guide 7, the hanging door plate 5 and the moving door plate 6 are formed in the horizontal frame 4 as shown in FIG. 6. It is folded up to a position that is substantially parallel to it.

  Thus, in addition to the guide groove 8 being formed without being licked and refracted, the start point 9 is positioned on the first direction side by the thickness α, and the end point 10 is positioned on the second direction side by the thickness β. Thus, the suspended door board 5 and the movable door board 6 are completely folded in the storage area 3. Moreover, neither the hanging door board 5 nor the movable door board 6 protrudes indoors or remains in the opening 21, and the opening 21 is completely opened.

  In addition, if it is a folding door in Embodiment 1, since the end point 10 of the guide groove 8 exists in the position exceeding the supporting member 2, the movable door board 6 is the same position as the end surface of the supporting member 2, or exceeds this. Folded in position. For this reason, even after a movable doorplate is folded like the folding door of a prior art, a part of movable doorplate does not remain in an opening part. As is clear from FIG. 5 and FIG. 6, the suspension door plate 5 and the movable door plate 6 have substantially the same width, and the end portions of the suspension door plate 5 and the movable door plate 6 all reach the pivot support position 11. Can reach.

  Since the pivot support position 11 is located at the boundary between the support member 2 and the opening 21, the end portions of the suspension door plate 5 and the movable door plate 6 can reach the pivot support position 11. As a result, the suspended door plate 5 and the movable door plate 6 are completely removed from the opening 21 to the outside. As a result, the opening 21 is completely opened without being shielded by the door plate. For this reason, the folding door 1 in Embodiment 1 can raise the open feeling of a room | chamber interior and the open feeling of the window provided in the interior space side to the maximum.

  Although FIG. 5 and FIG. 6 have described the case where there is a single guide groove, there may be a plurality of guide grooves, or a plurality of guide grooves may be connected. Here, when a plurality of guide grooves are connected, a refracted portion is generated at the connection position, but this is only caused by connecting a plurality of grooves, and only a single guide groove can be grasped. In this case, there is no refraction from the start point to the end point.

  5 and 6 show a form in which the suspension door plate 5 and the movable door plate 6 are connected to one support member 2, another support member is provided at a position where it is paired with the support member 2. The suspension door plate 5 and the movable door plate 6 may be sandwiched between the two support members, or the plurality of suspension door plates 5 and the movable door plate 6 may be sandwiched between the two support members. It may be.

  An intermediate door plate may be connected between the hanging door plate 5 and the movable door plate 6. In this case, at the connection position 12, the intermediate door plate is connected to the hanging door plate 5, and the other of the intermediate door plates is connected to the movable door plate 6. By connecting the intermediate door plates, the width of the folding door 1 is increased. When the folding door 1 is used as a partition in a large room, it is effective to widen the width of the folding door 1 using an intermediate door plate.

  In Embodiment 1, although the folding door 1 in which the suspension door board 5 and the movable door board 6 were installed was demonstrated, even if it is only the frame for folding doors in which the suspension door board 5 and the movable door board 6 are not installed, it is the above-mentioned. Has an effect. Even if it is only a frame for folding doors, the horizontal frame 4 is provided with a guide groove 8 that is oblique and has no refraction, and the guide groove 8 is smoothly connected to the suspension door plate 5 and the movable door plate 6 that are attached afterwards. It can be moved and folded. In the case of a folding door frame, the support member 2 and the horizontal frame 4 may be assembled. Further, the support member 2 and the horizontal frame 4 may be formed by extending the same members as the walls and the ceiling. The support member 2 may be an external element as an element constituting the folding door 1.

  Naturally, it may be distributed, provided, and sold in the state of the folding door 1, and may be distributed, provided, and sold in the state of the frame for the folding door. The mode of provision may be determined depending on the circumstances of distribution and sales. When only the folding door frame is provided and the folding door frame is attached to the house, the hanging door plate 5 and the movable door plate 6 may be attached. In addition, each member of the folding door 1 (each of the supporting member 2, the lateral frame 4, the hanging door plate 5, the movable door plate 6, etc.) is provided individually, and the individual members are lifted up at the assembly site of a house or building. The folding door 1 may be completed. The folding door 1 may be used as a door of furniture or fittings having a door such as a window frame, a shutter, a closet, or a built-in closet. Alternatively, it may be used as a room divider.

  Although not shown in the drawing, a support frame may be further provided in order to improve the strength of the frame formed by the support member 2 and the horizontal frame 4. The support frame connects the support members 2 to each other at, for example, the opening 21. (It may be substantially parallel to the horizontal frame 4 or may not be substantially parallel).

  As described above, according to the folding door in Embodiment 1, the door plate is smoothly moved and folded, and the opening is completely opened. Furthermore, since the folded doorboard is stored in a clean and overlapping manner with the support member located beside the doorboard, the appearance of the folded doorboard is very clean. In particular, since both the hanging door plate and the movable door plate are completely detached from the opening and folded, the feeling of opening in the room is enhanced, and a high-quality atmosphere is generated. In addition, the movement of the door plate is less likely to deteriorate as the usage period elapses.

(Embodiment 2)
Next, the second embodiment will be described with reference to FIGS. In the second embodiment, a folding door will be described in which two sets of hanging door plates and moving door plates are configured by four door plates. 7 and 8 are front views of the folding door according to Embodiment 2 of the present invention.

  FIG. 7 shows a state in which all the door plates are closed, and FIG. 8 shows a state in which the door plates are folded and the opening 21 is opened. The folding door 40 of FIGS. 7 and 8 includes two suspension door plates 5a and 5b and two movable door plates 6a and 6b, respectively. The folding door 40 includes the support member 2 as in the first embodiment, but the two support members 2a and 2b are provided at both ends, respectively. The movable door plate 6a includes a guide 7a that fits into the guide groove 8a, and the movable door plate 6b includes a guide 7b that fits into the guide groove 8b.

  The support member 2a connects the suspension door plate 5a at the pivot support position 11a. The suspension door plate 5a connects the movable door plate 6a at the connection position 12a. That is, the suspension door plate 5a and the movable door plate 6a are configured as a set with the pivot support position 11a as a base point.

  A region surrounded by the support member 2a, the support member 2b, the horizontal frame 4, and the floor is an opening 21 that is opened and closed by a door plate.

  Similarly, the support member 2b connects the suspension door plate 5b at the pivot support position 11b. The suspension door plate 5b connects the movable door plate 6b at the connection position 12b. That is, the suspension door plate 5b and the movable door plate 6b are configured as a set with the pivot support position 11b as a base point.

  The suspension door plate 5a and the movable door plate 6a are integrally opened and closed, and the suspension door plate 5b and the movable door plate 6b are integrally opened and closed. The suspension door plate 5a and the movable door plate 6a are closed from the support member 2a toward the center of the opening 21 with the pivot support position 11a as a base point, and are moved and folded toward the support member 2a with the pivot support position 11a as a base point. On the other hand, the suspension door plate 5b and the movable door plate 6b are closed from the support member 2b toward the center of the opening 21 with the pivot support position 11b as a base point, and moved toward the support member 2b with the pivot support position 11b as a base point. Then it can be folded. That is, the opening 21 is closed and opened by the set of the hanging door plate 5a and the movable door plate 6a and the set of the hanging door plate 5b and the movable door plate 6b. 7 and 8, two sets of hanging door plates and moving door plates have been described. However, the folding door 40 may include three or more sets of hanging door plates and moving door plates. You may have intermediate boards other than a hanging door board and a movable door board.

  7 and 8 show a state in which the folding door 40 is used as a partition in the middle of the room, but it is needless to say that a use mode other than the partition may be used. For example, after partitioning a part of the room, the inner space side (that is, the back of the folding door 40) may be used as a storage shelf or a closet. Or a window frame may be provided in the wall by the side of internal space, and the folding door 40 may be utilized as a blindfold of the wall containing a window frame.

  Thus, the folding door 40 can be used according to various aspects and situations.

(Guide groove structure corresponding to FIGS. 7 and 8)
Further, as is clear from FIG. 9, in the case of a folding door having two sets of hanging door plates and moving door plates as shown in FIGS. 7 and 8, the guide groove is connected to the two guide grooves. It has a form. FIG. 9 is an explanatory diagram of the guide groove in the second embodiment of the present invention. FIG. 9A shows the door panel as it is stretched, and FIG. 9B shows the folded door panel.

  The horizontal frame 4 of the folding door 40 includes two guide grooves 8a and 8b. Here, as is clear from FIG. 9A, the guide groove 8a and the guide groove 8b are connected to each other at the starting points 9a and 9b, and are physically a single groove. However, only the guide groove 8a and the guide groove 8b are connected for convenience at the start point 9a and the start point 9b, and the horizontal frame 4 has two guide grooves 8a and 8b. The guide groove 8a is slanted from the start point 9a to the end point 10a and has no refraction part, and the guide groove 8b is slanted from the start point 9b to the end point 10b and has no refraction part. Even if a plurality of guide grooves are connected to form a single guide groove from the viewpoint of ease of manufacturing, etc., each guide groove should be “oblique and have no refracting part from the start point to the end point”. It has the elements of the invention.

  The guide groove 8a has a start point 9a and an end point 10a, and extends from the approximate center of the horizontal frame 4 toward the support member 2a. As described above, from the start point 9a to the end point 10a, the guide groove 8a is oblique and not refracted (does not have a refracting portion that is a bent portion).

  Further, as described in the first embodiment, the position of the starting point 9a exists at a position moved by the thickness α in the first direction side with respect to the virtual straight line 30 that the pivot support position 11a forms substantially parallel to the horizontal frame 4. To do. That is, it is located on the first direction side of the virtual straight line 30 by the thickness α. Here, the thickness α is determined by the length from the front surface (interior side surface) of the movable door plate 6a to the guide 7a. The starting point 9b has the same positional relationship as the starting point 9a.

  Further, the end point 10a is present at a position moved by the thickness β toward the second direction side with respect to the virtual straight line 30. The second direction is a direction opposite to the first direction. Here, the thickness β is determined by a length obtained by adding the thickness from the back surface of the movable door plate 6a to the guide 7a to the thickness of the hanging door plate 5a. When the suspended door plate 5a and the movable door plate 6a are folded, the guide 7a should be positioned on the second direction side by the thickness β with respect to the virtual straight line 30. Since the guide groove 8a has a start point 9a and an end point 10a at a position necessary for the movement of the guide 7a, the suspension door plate 5a and the movable door plate 6a are located up to a position substantially parallel to the horizontal frame 4. Folded. Naturally, the end point 10b of the guide groove 8b has the same positional relationship as the end point 10a.

  As described above, the folding door 40 having two sets of the hanging door plate and the moving door plate has a configuration as shown in FIGS. 7 and 8, and the folding door plate and the moving door plate have two sets. The door 40 has a guide groove as shown in FIG. The folding door 40 stores two sets of hanging door plates and moving door plates in storage areas provided in each of the two support members.

(Operation of doorboard in FIGS. 7, 8 and 9)
The operation of the folding door 40 having two sets of the suspension door plate and the moving door plate shown in FIGS. 7 to 9 will be described.

  First, as shown in FIG. 9A, the folding door 40 has all the suspension door plates 5a and 5b and the movable door plates 6a and 6b extended to close the opening.

  The suspension door plate 5a is pivotally supported by the support member 2a at the pivot support position 11a. The movable door plate 6a is foldably connected to the hanging door plate 5a at the connection position 12a. A guide element 7a is provided at the tip of the movable door plate 6a so as to fit in the guide groove 8a. The guide 7a moves in the guide groove 8a. When the movable door plate 6a is pulled out, the guide 7a moves in the guide groove 8a, and the movable door plate 6a and the suspension door plate 5a are gradually expanded in the opening 21 while being bent in the second direction side (indoor side).

  When the guide element 7a comes close to the support member 2a, the movable door plate 6a and the suspension door plate 5a are combined and moved to the position of the support member 2a. When the guide 7a further advances through the guide groove 8a to the end point 10a, the movable door plate 6a and the suspension door plate 5a are folded into the storage area 3a. When folded, the movable door plate 6a and the suspended door plate 5a do not protrude from the horizontal frame 4 in a substantially parallel manner. In addition, as described in the first embodiment, since the movable door plate 6a and the suspended door plate 5a have the same width, a part of the door plate does not remain in the opening 21. Further, since the guide groove 8a is oblique and does not have a refracting portion from the start point 9a to the end point 10a, the guide 7a can move smoothly in the guide groove 8a. Even when the user moves the door plate, the door plate is not caught or clogged in the guide groove 8a, and it is not difficult to move the door plate. Further, even if the usage period is extended, there is no problem that the moving operation becomes difficult.

  Similarly, the suspension door plate 5b is pivotally supported by the support member 2b at the pivot support position 11b. The movable door plate 6b is foldably connected to the hanging door plate 5b at the connection position 12b. A guide element 7b is provided at the tip of the movable door plate 6b so as to fit into the guide groove 8b. The guide 7b moves in the guide groove 8b. When the movable door plate 6b is pulled to the front, the guide 7b moves in the guide groove 8b, and the movable door plate 6b and the suspension door plate 5b are bent to the indoor side and gradually widen the opening 21.

  When the guide 7b comes close to the support member 2b, the movable door plate 6b and the suspension door plate 5b are combined and moved to the position of the support member 2b. When the guide 7b further advances through the guide groove 8b to the end point 10b, the movable door plate 6b and the suspension door plate 5b are folded into the storage area 3b. When folded, the movable door plate 6b and the suspended door plate 5b are substantially parallel to the horizontal frame 4, so that the door plate does not protrude. In addition, as described in the first embodiment, since the movable door plate 6b and the suspended door plate 5b have the same width, a part of the door plate does not remain in the opening 21. Further, since the guide groove 8b is slanted from the start point 9b to the end point 10b and does not have a refracting part (the refracting part is bent), the guide 7b can move smoothly in the guide groove 8b. Even when the user moves the door plate, the door plate is not caught or clogged in the guide groove 8b, and it is not difficult to move the door plate. Further, even if the usage period is extended, there is no problem that the moving operation becomes difficult.

  FIG. 9B shows a state in which the door plate is folded, and the suspended door plate 5a and the movable door plate 6a moved along the guide groove 8a are folded on the surface of the support member 2a (support member 2a). Is the storage area 3a). Similarly, the suspended door plate 5b and the movable door plate 6b moved along the guide groove 8b are folded on the surface of the support member 2b.

  As described above, in the case of a folding door having two sets of hanging door plates and moving door plates as shown in FIGS. 7 and 8, the guide grooves are formed obliquely and without bending from the start point to the end point. Thus, two guide grooves are connected to each other at the starting points and provided in the horizontal frame. Each of the two guide grooves moves one of the set of the suspended door plate and the movable door plate. As a result, each of the set of the suspension door board and the movable door board is folded and stored in the storage area provided in each of the two support members.

  7 and 8, the door plate is folded on the surface of the support member (inside the room), so the first direction is the back side of the support member (inside the internal space 41) and the second direction. Is the front side (inside the room) of the support member.

  In FIG. 9, since the door plate is folded on the surface (inside the room) of the support member, the first direction is the back side of the support member and the second direction is the front side of the support member.

  In any case, the positions of the start point and the end point are determined based on the guides of the movable door plate. By having such a positional relationship between the start point and the end point, the hanging door plate and the movable door plate are completely opened in the opening portion 21 without being left inside the opening portion 21 and are neatly stored in the storage area.

  As described above, even with the folding door 40 having four door plates, the opening 21 is completely opened, and even a weak woman or child can easily open and close the door.

  Note that a window frame may be provided on the inner space side of the folding door 1 or the folding door 40, and the window frame and the folding door may be supplied as a set or installed. For example, you may distribute with the window with a folding door assembled with a window frame. Alternatively, the window frame and the folding door may be distributed separately, and the folding door may be lifted up by the window frame when the house or the building is assembled.

  Further, in the folding doors in the first and second embodiments, the support member 2 may be rotatable about the pivot support position 11. FIG. 10 is a schematic diagram of the folding door according to the second embodiment of the present invention, and FIG. 10 shows a state in which the support members 2a and 2b rotate around the pivot support positions 11a and 11b, respectively. . In addition, when the supporting members 2a and 2b rotate about the pivot positions 11a and 11b, the supporting members 2a and 2b or the suspension door plates 5a and 5b need to be fixed to the ceiling or the floor. In this case, the upper and lower sides of the supporting members 2a and 2b or the suspension door plates 5a and 5b may be connected to the ceiling or the floor in the vicinity of the pivot base point position by tenons or pins.

  The support members 2a and 2b are members serving as references for forming the storage areas 3a and 3b when the suspension door plates 5a and 5b and the movable door plates 6a and 6b are folded, but the suspension door plates 5a and 5b and the movable door plate 6a. , 6b may be completely folded, the support members 2a and 2b themselves may also rotate. This is because the support members 2a and 2b only need to be able to fix the pivot support positions 11a and 11b as the base points for the movement and rotation of the suspension door plates 5a and 5b and the movable door plates 6a and 6b.

  Since the support members 2a and 2b themselves can rotate, the portions of the support members 2a and 2b are opened, and the indoor side and the internal space side can pass through. For this reason, for example, articles can be passed from the position of the support members 2a and 2b to the internal space side or can be carried into a storage shelf or the like provided in the internal space. Since the supporting members 2a and 2b can rotate separately from the suspension door plates 5a and 5b and the movable door plates 6a and 6b to connect the internal space and the room, the usage mode of the folding door is further expanded. For example, the portions of the suspension door plates 5a and 5b and the movable door plates 6a and 6b are provided as human passages, and the portions of the support members 2a and 2b are provided as storage shelves hidden from the passages. Of course, the reverse is also possible.

  Depending on the installation location, the portion hidden by the support members 2a and 2b and the portion hidden by the suspension door plates 5a and 5b and the movable door plates 6a and 6b can be properly used. For this reason, the contractor who constructs the folding door described in Embodiments 1 and 2 can perform various constructions according to the situation of the building to be constructed, and install other furniture and interior decorations that match the folding door. Wide variety of construction, such as using properly.

  Thus, the support member 2a, 2b can be rotated, and the variation in construction of a folding door spreads.

  The modes described in the first and second embodiments are merely examples of the present invention, and include various modifications as long as the gist of the present invention is not impaired.
