[Figure 2] A perspective view showing a specific configuration example of an interlocking door, which is the first embodiment of the present invention. [Figure 3] A perspective view showing the main part of a modified example of the interlocking door, which is the first embodiment of the present invention. [Figure 4] A plan view conceptually illustrating the configuration and operation of an interlocking door, which is a second embodiment of the present invention. [Modes for carrying out the invention]

[0011] <First Embodiment> Figure 1 conceptually illustrates the configuration and operation of an interlocking door, which is a first embodiment of the present invention, in a plan view. The interlocking doors shown in the figure, for example, demarcate a crossing Y that crosses a passage X on which an automated guided vehicle travels, and consist of a pair of opening / closing doors 1A and 1B located at one entrance / exit Y1 and the other entrance / exit Y2 of the crossing Y. In this embodiment, the pair of opening / closing doors 1A and 1B each consist of two doors 11A, 12A and doors 11B, 12B, i.e., a total of four doors 11A, 12A, 11B, and 12B. As will be described in detail later, these four doors are connected by a link mechanism. When one of these four doors (for example, door 11A in Figure 1(a)) is rotated in the opening direction (direction of the solid arrow in Figure 1(a)), which is the direction that crosses the passage X, the other doors connected by the link mechanism rotate in conjunction in the opening direction (direction of the dashed arrow in Figure 1(b)), opening up to demarcate the crossing Y (Figure 1(c)). Furthermore, from this open state, if one of the four doors (for example, door 11B in Figure 1(d)) is rotated in the closing direction (in the direction of the solid arrow in Figure 1(d)), the other doors connected by the link mechanism will rotate in conjunction in the closing direction (in the direction of the dashed arrow in Figure 1(e)), closing the passageway Y and resulting in a closed state (Figure 1(f)).

[0012] Next, a specific example of the configuration of the interlocking doors will be explained. Figure 2 is a perspective view showing a specific example of the configuration of the interlocking doors. As shown in the figure, the four doors 11A, 12A, 11B, and 12B each include support columns 111A, 121A, 111B, and 121B that rotate in the opening or closing direction. The support columns 111A and 121A of the two doors 11A and 12A that constitute the opening and closing door 1A located at one entrance are connected by a first link mechanism 2. The support columns 111B and 121B of the two doors 11B and 12B that constitute the opening and closing door 1B located at the other entrance are connected by a second link mechanism 3. Furthermore, the first link mechanism 2 and the second link mechanism 3 are connected by a third link mechanism 4. Furthermore, the four doors 11A, 12A, 11B, 12B and the supporting columns 111A, 121A, 111B, 121B attached to them, as well as the first link mechanism 2, the second link mechanism 3, and the third link mechanism 4, are attached to a frame 5 consisting of four columns 51A, 51B, 51C, 51D and four beams 52A, 52B, 52C, 52D, forming an interlocking door system as a whole.

[0013] Next, the configurations of the first link mechanism 2, the second link mechanism 3, and the third link mechanism 4 will be described. The first linkage mechanism 2 includes a pair of right-angle gears 21A and 21B and a rod 22 connecting the pair of right-angle gears 21A and 21B. The right-angle gear 21A consists of a gear 211A attached to the upper end of the support column 111A and a gear 212A attached to one end of the rod 22, and transmits the axial rotation of the vertically positioned support column 111A to the axial rotation of the horizontally positioned rod 22. The right-angle gear 21B consists of a gear 211B attached to the upper end of the support column 121A and a gear 212B attached to the other end of the rod 22, and transmits the axial rotation of the vertically positioned support column 121A to the axial rotation of the horizontally positioned rod 22. The second link mechanism 3 has the same configuration as the first link mechanism 2 and includes a pair of right-angle gears 31A and 31B and a rod 32 connecting the pair of right-angle gears 31A and 31B. The right-angle gear 31A consists of a gear 311A ​​attached to the upper end of the support column 111B and a gear 312A attached to one end of the rod 32, and transmits the axial rotation of the vertically positioned support column 111B to the axial rotation of the horizontally positioned rod 32. The right-angle gear 31B consists of a gear 311B attached to the upper end of the support column 121B and a gear 312B attached to the other end of the rod 32, and transmits the axial rotation of the vertically positioned support column 121B to the axial rotation of the horizontally positioned rod 32. The third link mechanism 4 includes a link piece 41 attached to one end of the rod 22, a link piece 42 attached to one end of the rod 32, and a link bar 43 connecting the link piece 41 and the link piece 42, and transmits the axial rotation of the rod 22 to the axial rotation of the rod 32. That is, the third link mechanism 4 connects the first link mechanism 2 and the second link mechanism 2 so that the rod 22 of the first link mechanism 2 and the rod 32 of the second link mechanism 3 rotate in synchronization.

[0014] As described above, in this embodiment, the four doors 11A, 11B, 12A, and 12B are connected by the first link mechanism 2, the second link mechanism 3, and the third link mechanism 4. As described above, when one of these four doors is rotated in the opening direction, the other doors rotate in the opening direction in conjunction. Hereinafter, as an example, the interlocking of the other doors 12A, 11B, and 12B when the door 11A is rotated in the opening direction will be described for each door while referring to FIG. 2.

[0015] <Interlocking with Door 12A> (1) When the door 11A is rotated in the opening direction, the support column 111A of the door 11A rotates axially in the direction of arrow R1. (2) The axial rotation of the support column 111A is transmitted to the axial rotation of the rod 22 by the orthogonal gear 21A of the first link mechanism 2, and the rod 22 rotates axially in the direction of arrow R2. (3) The axial rotation of the rod 22 is transmitted to the axial rotation of the support column 121A of the door 12A by the orthogonal gear 21B of the first link mechanism 2, and the support column 121A rotates axially in the direction of arrow R3. (4) Due to the axial rotation of the support column 121A, the door 12A rotates in the opening direction.

[0016] <Interlocking with Door 11B> (1) When the door 11A is rotated in the opening direction, the support column 111A of the door 11A rotates axially in the direction of arrow R1. (2) The axial rotation of the support column 111A is transmitted to the axial rotation of the rod 22 by the orthogonal gear 21A of the first link mechanism 2, and the rod 22 rotates axially in the direction of arrow R2. (3) Due to the axial rotation of the rod 22, the third link mechanism 4 slides in the direction of arrow L. (4) The sliding of the third link mechanism 4 causes the rod 32 of the second link mechanism 3 to rotate axially in the direction of arrow R4. (5) The axial rotation of the rod 32 is transmitted to the axial rotation of the support column 111B of the door 11B by the orthogonal gear 31A of the second link mechanism 3, causing the support column 111B to rotate in the direction of arrow R5. (6) The door 11B rotates in the opening direction due to the rotation of the support column 111B.

[0017] <Linkage to Door 12B> (1) When the door 11A is rotated in the opening direction, the support column 111A of the door 11A rotates on its axis in the direction of arrow R1. (2) The axial rotation of the support column 111A is transmitted to the axial rotation of the rod 22 by the orthogonal gear 21A of the first link mechanism 2, causing the rod 22 to rotate in the direction of arrow R2. (3) The rotation of the rod 22 causes the third link mechanism 4 to slide in the direction of arrow L. (4) The sliding of the third link mechanism 4 causes the rod 32 of the second link mechanism 3 to rotate axially in the direction of arrow R4. (5) The axial rotation of the rod 32 is transmitted to the axial rotation of the support column 121B of the door 12B by the orthogonal gear 31B of the second link mechanism 3, causing the support column 121B to rotate in the direction of arrow R6. (6) The rotation of the support column 121B causes the door 12B to rotate in the opening direction.

[0018] Thus, when door 11A is rotated in the open direction, the other doors 12A, 11B, and 12B rotate in the open direction in conjunction, resulting in an open state that partitions the crossing Y as shown in Figure 1(c). Also, as described above, when one of the four doors is rotated in the closed direction from the open state, the other doors rotate in the closed direction in conjunction. Below, as an example, the linkage of the other doors 12B, 11A, and 12A when door 11B is rotated in the closed direction will be explained for each door.

[0019] <Linkage to Door 12B> (1) When the door 11B is rotated in the closing direction, the support column 111B of the door 11B rotates on its axis in the opposite direction to the direction of arrow R5 described above. (2) The axial rotation of the support column 111B is transmitted to the axial rotation of the rod 32 by the orthogonal gear 31A of the second link mechanism 3, causing the rod 32 to rotate in the opposite direction to the arrow R4 direction described above. (3) The axial rotation of the rod 32 is transmitted to the axial rotation of the support column 121B of the door 12B by the orthogonal gear 31B of the second link mechanism 3, causing the support column 121B to rotate in the opposite direction to the direction of arrow R6 described above. (4) The rotation of the support column 121B causes the door 12B to rotate in the closing direction.

[0020] <Interlocking to door 11A> (1) When the door 11B is rotated in the closing direction, the support column 111B of the door 11B rotates on its axis in the opposite direction to the direction of arrow R5 described above. (2) The axial rotation of the support column 111B is transmitted to the axial rotation of the rod 32 by the orthogonal gear 31A of the second link mechanism 3, causing the rod 32 to rotate in the opposite direction to the arrow R4 direction described above. (3) Due to the rotation of the rod 32, the third link mechanism 4 slides in the opposite direction to the direction of arrow L described above. (4) The sliding of the third link mechanism 4 causes the rod 22 of the first link mechanism 2 to rotate on its axis in the opposite direction to the direction of arrow R2 described above. (5) The axial rotation of the rod 22 is transmitted to the axial rotation of the support column 111A of the door 11A by the orthogonal gear 21A of the first link mechanism 2, causing the support column 111A to rotate in the opposite direction to the direction of arrow R1 described above. (6) The door 11A rotates in the closing direction due to the rotation of the support column 111A.

[0021] <Interlocking to door 12A> (1) When the door 11B is rotated in the closing direction, the support column 111B of the door 11B rotates on its axis in the opposite direction to the direction of arrow R5 described above. (2) The axial rotation of the support column 111B is transmitted to the axial rotation of the rod 32 by the orthogonal gear 31A of the second link mechanism 3, causing the rod 32 to rotate in the opposite direction to the arrow R4 direction described above. (3) Due to the rotation of the rod 32, the third link mechanism 4 slides in the opposite direction to the direction of arrow L described above. (4) The sliding of the third link mechanism 4 causes the rod 22 of the first link mechanism 2 to rotate on its axis in the opposite direction to the direction of arrow R2 described above. (5) The axial rotation of the rod 22 is transmitted to the axial rotation of the support column 121A of the door 12A by the orthogonal gear 21B of the first link mechanism 2, causing the support column 121A to rotate in the opposite direction to the direction of arrow R3 described above. (4) The rotation of the support column 121A causes the door 12A to rotate in the opening direction.

[0022] Thus, when door 11A is rotated in the open direction, the other doors 12A, 11B, and 12B rotate in the open direction in conjunction, resulting in a closed state that blocks the crossing Y, as shown in Figure 1(f). Figure 2 shows this closed state. As described above, the interlocking doors of this embodiment can demarcate a crossing path Y that traverses the passage X. This allows people to safely cross the passage X.

[0023] Although the first embodiment has been described above, the present invention is not limited to this embodiment. The main modifications are described below. Variant example (1) In this embodiment, the first link mechanism 2, the second link mechanism 3, and the third link mechanism 4 are positioned above each door, but they can also be positioned below each door. Furthermore, the configuration of each link mechanism is not limited to the configuration shown in Figure 2. For example, the third link mechanism 4 can be configured to include a pair of sprockets 44, 45 and a chain 46 connecting the pair of sprockets 44, 45, as shown in Figure 3. That is, the third link mechanism 4 shown in Figure 3 includes a sprocket 44 attached to the other end of the rod 22 of the first link mechanism 2, a sprocket 45 attached to the other end of the rod 32 of the second link mechanism 3, and a chain 46 connecting the sprockets 44 and 45, and transmits the axial rotation of the rod 22 to the axial rotation of the rod 32.

[0024] Variant example (2) In this embodiment, the opening / closing doors 1A and 1B are each composed of two doors, but the opening / closing doors 1A and 1B may each be composed of one door. In this case, to prevent the doors from interfering with each other when they rotate in the opening or closing direction, the door of opening / closing door 1A can be formed in a comb-like shape, and the door of opening / closing door 1B can be formed in a comb-like shape that is staggered from the door of opening / closing door 1A. Alternatively, the door of opening / closing door 1A can be provided only on the upper part of the support column, and the door of opening / closing door 1B can be provided only on the lower part of the support column opposite the support column on which opening / closing door 1A is installed, thereby avoiding interference between the doors. However, in this case, depending on the size of the automated guided vehicle and the configuration of the doors, a shortcut may be created between the passage X and the crossing Y. Therefore, to ensure complete safety, it is preferable that the opening / closing doors 1A and 1B each be composed of two doors, as in this embodiment.

[0025] <Second Embodiment> Figure 4 conceptually illustrates the configuration and operation of an interlocking door, which is a second embodiment of the present invention, in a plan view. The interlocking doors shown in the figure demarcate two passages, a first passage X' and a second passage Y', that intersect at an intersection. The interlocking doors consist of a pair of opening / closing doors 1A' and 1B' located at one entrance / exit X1' and the other entrance / exit X2' of the first passage X'. In this embodiment, the pair of opening / closing doors 1A' and 1B' each consist of one door 11A' and one door 11B', i.e., a total of two doors 11A' and 11B'. These two doors 11A' and 11B' are connected by a link mechanism (not shown). When one of these two doors (for example, door 11A') is rotated in the first direction (direction of the solid arrow in Figure 4(a)), which is the direction that demarcates the first passage X', the other door 11B' connected by the link mechanism rotates in conjunction in the first direction (direction of the dashed arrow in Figure 4(a)), resulting in the first state of demarcating the first passage X' (Figure 4(b)). Furthermore, from this first state, if door 11A' is rotated in a second direction opposite to the first direction (in the direction of the solid arrow in Figure 4(b)), the other door 11B' connected by the link mechanism will rotate in conjunction in the second direction (in the direction of the dashed arrow in Figure 4(b)), resulting in a second state where it partitions the second passage Y' (Figure 4(a)). In this embodiment, various well-known link mechanisms can be appropriately used as the link mechanism connecting the two doors 11A' and 11B'.

[0026] Thus, the interlocking doors of this embodiment can separate the two passages, the first passage X' and the second passage Y', that intersect at an intersection. This allows people to safely pass through either the first passage X' or the second passage Y'.

[0027] In this embodiment, the opening / closing door 1A and the opening / closing door 1B are each made up of one door, but as in the previous embodiment, the opening / closing door 1A and the opening / closing door 1B may each be made up of two doors.

[0028] As described above, the interlocking doors of the present invention can partition two passages, such as a crosswalk (Y) that crosses a passage (X), or a first passage (X') and a second passage (Y') that intersect at an intersection. This allows, for example, a person to safely cross a passage where an automated guided vehicle is traveling. Furthermore, with the interlocking doors of the present invention, when one passage (Y, Y') is partitioned, the other passage (X, X') is blocked by the doors, so, for example, when an important person is passing through, they can easily cross the passage (intersection) without being seen or seen by onlookers. In this case, the interlocking doors of the present invention also serve as a screen from the outside. [Explanation of Symbols]
