It is a figure which shows the folding door unit of a 4th modification.

  First, it will be described from the background that came to the idea of the folding door unit of the embodiment. FIG. 1A is a plan view schematically showing a folding door unit 100 of a reference example. The folding door unit 100 of the reference example constitutes a part of the partition wall 22 using a plurality of folding doors guided by the guide rail 24. The partition wall 22 has a corner portion 22c. In the present specification, the center of the groove width of a rail groove 24d (described later) of the guide rail 24 is indicated by a one-dot chain line.

  The folding door unit 100 includes a unit folding door 20 having a first door body 28 and a second door body 30, and a corner vertical gutter 25 that constitutes a corner portion 22 c of the partition wall 22. The corner vertical gutter 25 is connected to the first door body 28 disposed on the side of the partition wall 22 close to the corner portion 22c.

  The corner vertical rod 25 has a rod guide 42 that is guided by the guide rail 24 with rotation around the guide shaft 46. The first door body 28 and the second door body 30 have a door guide 44 that is guided by the guide rail 24 with rotation around the guide shaft 46.

  The guide rail 24 includes a first straight section 24a and a second straight section 24b that extend in different directions, and a corner section 24c that forms a corner that connects the first straight section 24a and the second straight section 24b. The first straight section 24 a is arranged in the vertical direction with respect to the unit folding door 20 of the folding door unit 100. The second straight section 24 b is arranged in the vertical direction with respect to the other folding door 18 adjacent to the folding door unit 100. These positional relationships are based on the premise that when the partition wall 22 is formed, the folding door 18 or the folding door unit 100 is located at a position (hereinafter referred to as a partitioning position).

  Consider a case in which the folding door unit 100 at the partition position is moved so as to pass through the corner section 24c of the guide rail 24. In this case, the external force Fa toward the second straight section 24b is applied to the corner vertical wall 25. At this time, the external force Fa applied to the corner downside 25 is transmitted to the first door 28 adjacent to the corner downside 25. As a result, the door guide 44 hits the guide rail 24, and the first door body 28 cannot move in the same direction as the external force Fa applied to the corner hoist 25. The external force Fa applied to the corner downer 25 is converted into a rotational force Fb around the guide shaft 46 of the first door 28. The rotational force Fb is applied in the direction in which the unit folding door 20 is folded. For this reason, as shown in FIG.1 (b), when passing the corner area 24c of the guide rail 24, the folding operation | movement of the unit folding door 20 will be needed.

  If the folding operation of the unit folding door 20 is required, if there is an obstacle 102 in the vicinity of the unit folding door 20, it interferes with the obstacle 102 with the folding operation, and the unit folding door 20 is further moved. Can become unfoldable. As a result, the folding door unit 100 cannot be moved so as to pass through the corner section 24c of the guide rail 24, which adversely affects the usability.

  FIG. 2 shows the folding door unit 10 of the embodiment in which this countermeasure is taken. The folding door unit 10 of the embodiment has guides 42 and 44 in which only the corner downside 25 and the second door 30 are guided to the guide rail 24 with rotation around the guide shaft 46, and the first door 28 is Does not have such a guide. This is because the corner vertical fence 25 and the second door 30 are provided with locations that are guided by contact with the guide rail 24, and the first door 28 is provided with a location that is guided by contact with the guide rail 24. Is not provided. Thereby, when the corner vertical fence 25 and the second door 30 are guided to the guide rail 24 via the guides 42 and 44, the first door 28 is not restrained by the guide rail 24. Relative displacement is allowed.

  Consider the case where an external force Fa toward the second straight section 24b is applied to the corner vertical wall 25 using the folding door unit 10 as described above. In this case, when the external force Fa is transmitted to the corner vertical shaft 25, a situation in which the guide of the first door 28 hits the guide rail 24 does not occur. The external force Fa applied to the corner vertical rod 25 is transmitted together with the first door body 28 to the second door body 30, and is converted into a rotational force Fc around the guide shaft 46 of the second door body 30. The rotational force Fc is applied in a direction in which the unit folding door 20 is extended, and rotates the unit folding door 20 around the guide shaft 46 while avoiding the folding operation of the unit folding door 20.

  As a result, as shown in FIG. 2B, when the folding door unit 10 is moved so as to pass through the corner section 24c of the guide rail 24, the folding operation of the unit folding door 20 can be avoided. Accordingly, the folding door unit 10 can be moved while avoiding interference with the obstacle 102 due to the folding operation of the unit folding door 20, and good usability can be obtained. Hereinafter, details of the folding door unit 10 will be described.

As for a pair of guide wall part 24e, the mutual front-end | tip part is faced | matched by the expectation direction Y (it mentions later).

  The description of the folding door unit 10 will be described. FIG. 8 is an enlarged view of the folding door unit 10 of FIG. The folding door unit 10 includes a unit folding door 20 and a corner vertical gutter 25 that constitutes a corner portion 22 c of the partition wall 20. In this specification, when the unit folding door 20 of the folding door unit 10 is in the extended state, the left-right direction when the folding door unit 10 is viewed from the front is referred to as a door width direction Pa, and the depth direction is sometimes referred to as a forecast direction Pb. Here, the extended state refers to a state in which the first door body 28 and the second door body 30 of the unit folding door 20 are extended linearly.

  The unit folding door 20 includes a first door body 28 and a second door body that are rotatable about the rotation shaft 32 by connecting inner ends 28a and 30a in the door width direction Pa via the rotation shaft 32. 30. The first door body 28 is disposed closer to the corner portion 22 c of the partition wall 22 than the second door body 30. The first door body 28 and the second door body 30 are provided with bearing portions 33, and individual rotation shafts 32 are rotatably supported by the bearing portions 33. In the embodiment, the two rotating shafts 32 constitute a part of an integrated part. The rotation shaft 32 extends in the vertical direction, and is provided between the first door body 28 and the second door body 30 on the internal space side (one side) in the expected direction Y.

  FIG. 9 is a view of a part of the folding door unit 10 as seen from the expected direction Y. FIG. As shown in FIGS. 8 and 9, the door bodies 28 and 30 include a rectangular panel body 34 such as a translucent glass panel, and flanges 36 and 38 that surround the four circumferences of the panel body 34. The eaves 36 and 38 include two vertical eaves 38 on both sides in the door width direction Pa.

  The corner downer 25 has a long and hollow structure in the vertical direction as a whole. The corner downer 25 is connected to the outer end 28b of the first door 28 in the door width direction Pa. Thereby, when it is necessary to slide the folding door 20 for units and the corner vertical shaft 25 along the guide rail 24, these can be moved integrally. For example, as shown in FIG. 5, a case is assumed in which a plurality of folding doors 18 and folding door units 10 are collected in one place.

  The folding door unit 10 of the embodiment includes a hinge mechanism 40 that connects the outer end portion 28b of the first door body 28 and the corner vertical shaft 25 so as to be rotatable around the hinge shaft 40a. The hinge mechanism 40 of the embodiment is a single-axis hinge mechanism having a single hinge shaft 40a. The hinge shaft 40a extends in the vertical direction, and is provided on the outer space side (the other side) in the expected direction Y between the first door body 28 and the corner vertical rod 25.

  Here, as described above, in the folding door unit 10 of the embodiment, the corner vertical fence 25 and the second door 30 have the guides 42 and 44 guided by the guide rail 24, and the first door 28 has the guide. There is a feature not to do. This point will be described in detail.

  Please refer to FIG. The corner vertical rod 25 includes an upper rod guide 42 -A guided by the upper guide rail 24 and a lower rod guide 42 -B guided by the lower guide rail 24. The upper hook guide 42-A is provided at the upper end of the corner vertical hook 25, and the lower hook guide 42-B is provided at the lower end of the corner vertical hook 25.

  The second door 30 includes an upper door guide 44 -A guided by the upper guide rail 24 and a lower door guide 44 -B guided by the lower guide rail 24. The upper door guide 44 -A is provided at the upper end portion of the vertical fence 38 at the outer end portion 30 b of the second door body 30, and the lower door guide 44 -B is provided at the lower end portion of the vertical fence 38.

  Since the upper side guide 42-A, the lower side guide 42-B, the upper side door guide 44-A, and the lower side door guide 44-B are common in many respects, these common points will be described with generic names. Sometimes. The generic name here refers to a name in which “upper side, lower side” at the beginning and “-A, -B” at the end are omitted.

  The upper side guide 42-A and the lower side guide 42-B of the embodiment include a guide shaft 46 that protrudes from the corner vertical side 25 to both sides in the vertical direction, and a roller 48 that is rotatably attached to the distal end portion of the guide shaft 46. Have The upper door guide 44 -A and the lower door guide 44 -B of the embodiment are also rotatable to the guide shaft 46 protruding from the outer end portion 30 b of the second door body 30 on both sides in the vertical direction and the tip end portion of the guide shaft 46. And a roller 48 attached thereto.

  Please refer to FIG. The guide shaft 46 is disposed in the rail groove 24 d of the guide rail 24. The guide shaft 46 is guided by the guide rail 24 by sliding along the rail groove 24 d of the guide rail 24. The roller 48 is disposed on the back side of the pair of guide wall portions 24 e of the guide rail 24. The roller 48 is guided by the guide rail 24 by rolling along the inner wall surface of the guide rail 24.

  In the upper heel guide 42 -A and the upper door guide 44 -A of the embodiment, the roller 48 is supported by the guide wall portion 24 e of the upper guide rail 24. Thereby, the corner vertical rod 25 and the second door body 30 are supported by the upper guide rail 24 via the upper rod guide 42-A and the upper door guide 44-A. When the lower side guide 42-B and the lower door guide 44-B of the embodiment are to be displaced upward, the displacement is caused by the contact between the guide wall portion 24e of the lower guide rail 24 and the roller 48. It can be regulated.

  Under the above configuration, the folding door unit 10 is guided to the guide rail 24 along with the folding operation and the extension operation of the unit folding door 20, and can be opened and closed through the folding operation and the extension operation. At this time, as shown in FIG. 8, the folding door unit 10 rotates the corner vertical rod 25 and the first door body 28 in the direction P1 around the guide shaft 46 of the rod guide 42, and the guide shaft 46 of the door guide 44. It can be opened and closed with the rotation of the second door 30 in the surrounding direction P2.

  Here, as described above, the corner vertical rod 25 and the second door 30 have the rod guide 42 and the door guide 44 that are guided by the guide rail 24 with the rotation around the guide shaft 46. On the other hand, the first door body 28 does not have a guide that is guided by the guide rail 24 with rotation around the guide axis. Thus, as described above, when the folding door unit 10 is moved so as to pass the corner section 24c of the guide rail 24, the folding operation of the unit folding door 20 can be avoided.

  FIG. 10 is a diagram illustrating the folding door unit 10 of the first modification. The folding door unit 10 of the first modified example is different from the folding door unit 10 of the embodiment in that the corner vertical wall 25 and the first door body 28 are integrated so as not to be relatively displaced. In configuring the partition wall 22, consider the case where the unit folding door 20 is located at the partition position where the unit folding door 20 should be disposed. At this time, when folding the unit folding door 20, the direction in which the inner end portions 28a, 30a of the first door body 28 and the second door body 30 start moving is defined as an opening direction Pc. Consider a case where an obstacle is arranged in the opening direction Pc with respect to the outer end portion 28b of the first door body 28. The obstacle in this example is the column 14 of the outdoor structure 12.

  Under this case, in the folding door unit 10 of the first modified example, the first door body 28 can only rotate around the guide shaft 46 of the rod guide 42, and the outer end portion 28b of the first door body 28 is an obstacle. It becomes easy to interfere with.

  On the other hand, the folding door unit 10 of the embodiment includes a hinge mechanism 40 that connects the outer end portion 28b of the first door body 28 and the corner vertical rod 25 so as to be rotatable around the hinge shaft 40a. Therefore, as shown in FIG. 11, the outer end portion 28b of the first door 28 can be moved in the direction Pe away from the obstacle on the side opposite to the opening direction Pc. This can be realized by rotating the first vertical body 28 and the corner vertical rod 25 around the hinge shaft 40 a while rotating the corner vertical rod 25 in the direction Pd around the guide shaft 46 of the rod guide 42. Thereby, it becomes easy to open the unit folding door 20 while avoiding interference between the outer end portion 28b of the first door body 28 and an obstacle.

Next, other features of the folding door unit 10 will be described.
FIG. 12 is a diagram showing the guide rail 24 and the saddle guide 42 and the surrounding structure in a simplified manner. The guide shaft 46 of the eaves guide 42 is disposed in the rail groove 24 d that constitutes the second straight section 24 b of the guide rail 24. As a result, the guide shaft 46 of the rod guide 42 is disposed at a position where it can abut on the wall surface of the guide rail 24 that constitutes the second straight section 24b in the extending direction X of the first straight section 24a. In the present embodiment, the extending direction X of the first straight section 24a is the frontage direction X. This advantage will be described.

  FIG. 13 is a view showing the folding door unit 10 of the second modification. In the folding door unit 10 of the second modified example, the guide shaft 46 of the eaves guide 42 is disposed in the rail groove 24 d that constitutes the corner section 24 c of the guide rail 24. In this case, a case is considered in which the folding door unit 10 is arranged at the partition position while the folding door unit 10 is guided by the first straight section 24a of the guide rail 24. In this case, an external force Fd in the extending direction X of the first straight section 24a is input to the folding door unit 10 so that the folding door unit 10 is guided along the first straight section 24a of the guide rail 24. At this time, the external force Fd input to the folding door unit 10 causes an overrun in which the guide shaft 46 of the heel guide 42 is guided in the direction Pf along the corner section 24c. As a result, it becomes difficult to position the folding door unit 10 in the extending direction X of the first straight section 24a.

  On the other hand, according to the embodiment, as shown in FIG. 12, when the external force Fd along the extending direction X of the first straight section 24a is input to the folding door unit 10, the second straight section of the guide rail 24 is provided. The guide shaft 46 of the eaves guide 42 abuts against the wall surface constituting 24b. Thereby, when it is going to stop the folding door unit 10 in a partition position, the overrun in which the corner vertical fence 25 is guided along the corner area 24c can be prevented. As a result, the folding door unit 10 can be easily positioned in the extending direction X of the first straight section 24a.

  Note that, under this configuration, compared to the second modification of FIG. 13, the amount of movement of the corner vertical fence 25 in the direction Pg away from the folding door 18 adjacent to the folding door unit 10 (hereinafter referred to as the adjacent folding door 18) is as follows. Can be big. Therefore, while avoiding interference with the adjacent folding door 18, the corner vertical rod 25 can be easily rotated around the guide shaft 46 of the rod guide 42, and the unit folding door 20 can be easily opened.

  FIG. 14A is an enlarged view showing a part of FIG. As shown in FIG. 12 and FIG. 14A, the folding door unit 10 has a lock member 50 that can lock the corner vertical shaft 25 to the guide rail 24. When the corner vertical shaft 25 is locked to the guide rail 24, the corner vertical shaft 25 has a role of easily positioning the unit folding door 20 and the adjacent folding door 18 by abutting against each other.

  The lock member 50 is built in the corner vertical shaft 25. The lock member 50 is supported so as to be movable up and down with respect to the corner vertical shaft 25. An operation member (not shown) is supported by the corner downside shaft 25 so as to be able to be raised and lowered, and the lock member 50 is raised and lowered in conjunction with a manual operation on the operation member. As shown in FIGS. 14 (a) and 14 (b), the lock member 50 moves up and down with respect to the corner vertical fence 25, so that the protruding amount in the vertical direction from the corner vertical fence 25 changes, and the guide rail 24. The rail groove 24d is inserted and removed.

  As shown in FIG. 12, the lock member 50 is inserted into and removed from the rail groove 24 d in the first section 50 a of the guide rail 24 that is inserted into and removed from the rail groove 24 d and the corner section 24 c of the guide rail 24. A second portion 50b. The first portion 50 a and the second portion 50 b of the lock member 50 according to the embodiment have a shape that can be fitted into the first straight section 24 a and the corner section 24 c of the guide rail 24.

  The lock member 50 is inserted into the rail groove 24d of the guide rail 24 and comes into a locked state in which the corner vertical rod 25 is locked to the guide rail 24 by abutting against the wall surface constituting the first straight section 24a of the guide rail 24. Become. When the lock member 50 is in the locked state, the lock member 50 is disposed at a position where it can contact the wall surface of the guide rail 24 that constitutes the first straight section 24a in the extending direction Y of the second straight section 24b. Is locked in the direction Y. In the present embodiment, the extending direction Y of the second straight section 24b is the outgoing width direction Y. When the lock member 50 is extracted from the rail groove 24d of the guide rail 24 and is in a position where it cannot be contacted horizontally with the wall surface of the guide rail 24 that constitutes the first straight section 24a, The unlocked state allows 25 relative displacements.

  The lock member 50 can be switched to be locked or not by moving up and down with respect to the rod guide 42 of the corner vertical rod 25. This advantage will be described.

  In order to firmly lock the corner vertical rod 25 using the lock member 50, it is preferable that the overlap margin in the vertical direction of the lock member 50 with respect to the guide rail 24 is larger when the lock member 50 is in the locked state. In order to realize this, it is preferable that the stroke amount of the lock member 50 in the ascending / descending direction can be increased.

  Consider the case where the rod guide 42 of the corner vertical rod 25 and the lock member 50 can be moved up and down integrally. Since the scissors guide 42 serves the purpose of being guided by the guide rail 24, an overlap margin in the vertical direction with respect to the guide rail 24 is required regardless of whether or not the lock member 50 is locked. Therefore, when the stroke amount of the lock member 50 is increased, an extra height dimension of the guide rail 24 is ensured so that the rod guide 42 that moves up and down in conjunction with the lock member 50 does not interfere with the guide rail 24. Will have to do.

  On the other hand, in the embodiment, it is possible to switch the presence or absence of the lock by raising and lowering the lock member 50 with respect to the hook guide 42 of the corner vertical hook 25. In this case, when the stroke amount of the lock member 50 is increased, the hook guide 42 does not move up and down in conjunction with the lock member 50, so that the height of the guide rail 24 is avoided in order to avoid interference between the hook guide 42 and the guide rail 24. It is not necessary to secure extra. As a result, the stroke amount of the lock member 50 can be increased while suppressing an increase in the height dimension of the guide rail 24, and the corner vertical rod 25 can be firmly locked to the guide rail 24 using the lock member 50.

  Please refer to FIG. A central position Cp between the guide shaft 46 of the heel guide 42 and the guide shaft 46 of the door guide 44 is located between the inner end portion 28 a of the first door body 28 and the inner end portion 30 a of the second door body 30. Is provided. In order to realize this, the door width dimension which is a dimension along the door width direction Pa of the first door body 28 is set to be smaller than the door width dimension of the second door body 30. This advantage will be described.

  Fig.15 (a) is a figure which shows a part of the folding door unit 10 of a 3rd modification. In this figure, the unit folding door 20 of the folding door unit 10 is in a folded state. In the folding door unit 10 of the third modified example, the first door body 28 and the second door body 30 have the same door width dimension. In this case, the first door 28 and the corner vertical wall 25 (location of the space Sa) must be arranged side by side in the direction Ph along the guide rail 24, and the dimension of the folding door unit 10 in the direction Ph is excessive. Increase.

  FIG.15 (b) is a top view which shows the state which folded the unit folding door 20 of embodiment. Since the folding door unit 10 of the embodiment satisfies the above-described conditions, when the unit folding door 20 is in the folded state, the first door body 28 and the corner vertical wall 25 are placed in the door width direction Pa of the first door body 28. Are lined up. Thereby, when the unit folding door 20 is in the folded state, it is not necessary to arrange the first door body 28 and the corner vertical wall 25 side by side in the direction Ph along the guide rail 24. Therefore, the size of the folding door unit 10 in the direction Ph along the guide rail 24 can be reduced.

  FIG. 16 is a diagram illustrating the folding door unit 10 of the fourth modified example. In the folding door unit 10 of this example, free relative displacement around the hinge shaft 40a of the first door body 28 and the corner vertical wall 25 is allowed. Consider a case in which external force Fe is applied to the first door body 28 toward the second door body 30 in order to guide the folding door unit 20 of the folding door unit 10 along the guide rail 24 in a folded state. . In this case, since free relative displacement between the first door body 28 and the corner vertical shaft 25 is allowed, even if an external force Fe is applied to the first door body 28, the external force Fe is a corner in the same direction. It becomes difficult to be smoothly transmitted to the downspout 25. As a result, the entire folding door unit 10 may be difficult to move smoothly along the guide rail 24.

  As a countermeasure, the folding door unit 10 according to the embodiment includes a position holding mechanism 54 that can hold the first door body 28 and the corner vertical wall 25 in a relative position when fully closed, as shown in FIG. Here, when fully closed, the folding door unit 10 is also in the partition position.

  The position holding mechanism 54 of the embodiment uses the attractive force of the magnets 54 a and 54 b as a holding force for holding the relative position between the first door body 28 and the corner vertical rod 25. Specifically, the position holding mechanism 54 includes a first magnet 54a attached to one of the butted portions of the corner downside 25 and the first door body 28, and a second magnet 54b attached to the other of the butted portions. The first magnet 54a and the second magnet 54b are magnetized with different polarities. The first magnet 54a and the second magnet 54b act as a holding force by an attractive force attracting each other when the first door body 28 and the corner vertical shaft 25 are in the relative positions when fully closed. When the first door 28 and the corner vertical rod 25 are given an external force that overcomes the holding force in the direction Pj against the holding force, the first door 28 and the corner vertical rod 25 can be relatively displaced with rotation around the hinge shaft 40a.

  According to this, when the unit folding door 20 is in the folded state, when the external force Fe is applied to the first door 28 toward the second door 30 to be guided along the guide rail 24, the external force Are easily transmitted to the corner downer 25 as a force in the same direction. As a result, the entire folding door unit 10 can be easily moved along the guide rail 24 using the external force Fe applied to the first door body 28.
