  The door device G according to the first embodiment is one that is used for opening and closing the passages of various facilities such as public facilities, commercial facilities, and hospitals. The door device G includes a pair of left and right doors 1 that open and close the passage T. An upper frame 2 is provided above the door 1 so as to cross the passage T, and an upper support mechanism 3 is provided in the upper frame 2. In addition, a lower support mechanism 5 is disposed below the door 1 so as to be embedded in the passage T. The upper support mechanism 3 and the lower support mechanism 5 support the door 1 so as to be rotatable about the side end portion of each door 1 and to be movable back and forth in the passage direction. As a result, the door 1 is configured to be openable / closable and movable back and forth. Both the upper support mechanism 3 and the lower support mechanism 5 correspond to the guide support mechanism in the present invention.

  FIG. 4 is a perspective view showing the opening / closing structure of the door 1. An upper end of the door 1 is provided with a guide rail 4 having a constant thickness formed in a flat annular elliptical shape along the longitudinal direction of the door. Further, the upper support mechanism 3 includes a pair of roller-shaped guide members 6 and 7 that are arranged opposite to each other in parallel at a predetermined interval at a passage side location. The guide rail 4 is held between the guide member 6 at the outer side and the guide member 7 at the inner side so as to be rotatable.

  A guide rail 8 having the same specifications is also provided on the lower end surface of the door 1 downward. The lower support mechanism 5 includes a pair of roller-shaped guide members 9 and 10 that are concentric with the above-described guide members 6 and 7 on the passage floor so as to freely rotate. And the guide rail 8 is clamped by these guide members 9 and 10 from inside and outside.

  Here, the guide members 6 and 7 and the guide rail 4 and the guide members 9 and 10 and the guide rail 8 need to be in contact with each other without relative slip. As an example of the means, the main part about the guide rail 4 and the guide members 6 and 7 is illustrated in FIG. As shown in FIG. 5, the gear portion 11 is formed on the outer peripheral surface of the guide member 6 that contacts the outside of the guide rail 4, and the gear portion 12 that meshes with the gear portion 11 is formed over the entire outer periphery of the guide rail 4. Is effective.

  According to the above configuration, when the contact point between the guide member 6 and the guide rail 4 is determined, the minimum rail thickness direction at the contact point matches the center line L connecting the guide members 6 and 7. The posture, that is, the posture of the door 1 is uniquely determined.

  In addition, although illustration is abbreviate | omitted, the contact part of the guide members 9 and 10 and the guide rail 8 is preferable to comprise as shown in FIG.

  In addition, an extension spring 13 is attached to the approximate center of the door 1 in the longitudinal direction of the door. At the upper end of the door 1, a spring support piece 14 is erected so as to be rotatable at the approximate center in the longitudinal direction of the door. Further, a stopper 15 is provided in the approximate center of the upper frame 2. One end of the extension spring 13 is locked to the spring support piece 14, and the other end is attached to the stopper 15. The stopper 15 supports two extension springs 13 attached to the left and right doors 1. The extension spring 13 corresponds to the elastic body in the present invention.

  Next, operation | movement of this door apparatus G is demonstrated based on the stroke diagram of FIGS.

  When the door device G is closed (the state shown in FIG. 6 or 12), each door 1 is in the closed position. At this time, the top of one end of the guide rail 4 in each door 1 is sandwiched between the guide members 6, 7, and the top (end) of the small curvature of one end of the guide rail 8 is the guide members 9, 10. It is in the state of being pinched by. In addition, in FIGS. 6 to 12, it is assumed that a passing object M such as a passerby passes through the door device G from the left to the right.

  In FIG. 7, a passing object M such as a passerby presses the pair of doors 1 in the traveling direction. In addition, in FIG. 7 etc., the force F which acts on the door 1 with the passing thing M is shown typically. As a result, the door 1 is opened in the traveling direction of the passage T integrally with the guide rails 4 and 8 with the tops of the guide rails 4 and 8 held between the guide members 6 and 7 and the guide members 9 and 10 as the center point. Swing. At this time, the pair of guide members 6 and 7 also allow the door 1 to rotate by rolling in response to the opening swing of the door 1. Further, the opening swing of the door 1 increases the distance between the spring support piece 14 and the stopper 15, and the extension spring 13 is extended and deformed. As a result, the door 1 is biased in the direction of the stopper 15 by the restoring force accumulated in the extension spring 13.

  As shown in FIG. 8, the passing object M further applies a force F to the door 1 so that the door surface of the door 1 is along the passage wall (the longitudinal surface of the door 1 is substantially parallel to the passage wall). State).

  In FIG. 9, the passing object M causes the door 1 to apply a force F in the direction opposite to the traveling direction. Thereby, the door 1 moves rearward along the passage wall without being in the way of the passing object M in the open posture. The force F in the direction opposite to the traveling direction continues to act at least until the center of the door longitudinal direction is opposite to the traveling direction with respect to the contact point between the guide members 6 and 7 and the guide rail 4.

  In FIG. 10, when the center in the longitudinal direction of the door is opposite to the traveling direction with respect to the contact point between the guide members 6 and 7 and the guide rail 4, the passing object M is separated from the door 1 and no force is applied to the door 1. The state that does not act. At this time, the force acting on the door 1 is only the restoring force of the extension spring 13, and this restoring force acts in the direction of the stopper 15. According to such restoring force, the contact point between the guide members 6 and 7 and the guide rail 4 reaches the vicinity of the other top of the guide rail 4, and the contact point between the guide members 9 and 10 and the guide rail 8 is the guide rail. 8 near the top of the other.

  In FIG. 11, in accordance with the restoring force of the extension spring 13, the door 1 is further swung forward and swinging forward about the contact portion between the guide members 6, 7 (9, 10) and the guide rail 4 (8). Then, it quickly moves behind the traffic object M and moves to the closed position where the passage T is closed (FIG. 12).

  As described above, in the door device G of this example, when the passing object M opens the door 1, the extension spring 13 is extended and deformed according to the opening movement of the door 1, and the door 1 is urged toward the closed position. The restoring force is accumulated in the extension spring 13. And since it comprised so that the door 1 might be closed and moved by the restoring force of the expansion | extension spring 13, the trouble that the to-be-passed object M closes and moves the door 1 can be saved. Further, by providing the extension spring 13, a simple configuration can be achieved without separately providing a power source such as a motor. Furthermore, since the upper support mechanism 3 and the lower support mechanism 5 guide the door 1 that has been moved to open to the closed position while wrapping behind the article M, the passage of the article M is not hindered.

  13 and 14 are a plan view and a front view of the door device according to the second embodiment, FIG. 15 is an enlarged view showing a holding mechanism of the door device, and FIG. 16 shows a door opening / closing structure of the second embodiment. FIGS. 17A and 17B are plan views showing the door opening and closing structure of the fifth embodiment. In addition, about the same structure as Example 1, detailed description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  The upper and lower ends of the door 1 in this example are provided with guide portions 21 that are formed in an elliptical shape that is flat in the longitudinal direction of the door, and an endless belt 22 is wound around each guide portion 21. Further, a rotary body 23 is provided at a predetermined position near the side edge of the door 1 and on the side of the door 1 so as to be rotatable about the vertical axis. An endless belt 22 wound around each guide portion 21 is wound around the rotating body 23. Further, a pair of front and rear guide rollers 24 for guiding the winding of the endless belt 22 around the rotating body 23 is provided at a fixed position between the rotating body 23 and the door 1. The guide rollers 24 are provided so as to be slidable in directions close to each other, and are urged in directions close to each other by spring members (not shown) to press the endless belt 22 with an appropriate force. In this way, the endless belt 22 is configured to be rotatable, thereby allowing the door 1 to swing open and move back and forth. The endless belt 22, the rotating body 23, and the guide roller 24 form a guide support mechanism that supports the door 1.

  Here, it is necessary that the guide portion 21 and the endless belt 22 are in contact with each other without relative slip. An example of the means is illustrated in FIG. As shown in the figure, the endless belt 22 is constituted by a toothed belt (timing belt) having a tooth portion 25 on the inner periphery, and a tooth portion 26 that meshes with the tooth portion 25 is formed on the entire outer periphery of the guide portion 21. Is effective. Further, it is desirable that the rotating body 23 also includes a tooth portion 27 that meshes with the endless belt 22.

  In addition, the pair of guide rollers 24 is preferably arranged so as to be aligned in the same direction as the passage T. The guide roller 24 is preferably arranged in relation to the rotating body 23 so that the line connecting the center point between the guide rollers 24 and the rotating body 23 is perpendicular to the passage T. Further, the separation between the guide rollers 24 is preferably smaller than the thickness of the door 1 (the length of the door 1 in the minor axis direction). Thereby, the movement (posture) of the door 1 can be suitably regulated by the pair of guide rollers 24. That is, the circumscribed line in the vicinity of the center of the pair of guide rollers 24 when viewed in plan is restricted so as to be always substantially parallel to the line connecting the pair of guide rollers 24 (that is, the passage direction).

  The lower end of the door 1 is provided with a guide rotating member 29 such as a ball or a caster wheel that rolls and moves on the floor of the passage to support the weight of the door 1.

  Furthermore, a holding mechanism 31 that holds the door 1 is provided at the upper and lower ends of each door 1. As shown in FIG. 16, the holding mechanism 31 includes a bearing member 34 in which an upper bearing portion 32 and a lower bearing portion 33 are connected to each other in a vertically rotatable manner, and a first rail 35 and a second rail 36. The first rail 35 extends to the upper end of the door 1 so as to connect both side ends in the longitudinal direction of the door 1. The lower bearing portion 33 is provided so as to be slidable (slidable) along the first rail 35, and only the shaft portion of the lower bearing portion 33 protrudes from the upper surface of the door 1. A second rail 36 is fixedly laid in the upper frame 2 in a direction crossing the passage T. That is, the second rail 36 is provided in parallel with the first rail 35 when the door 1 is in the closed position. One end of the second rail 36 is positioned at substantially the same position as the top of the door 1 on the passage side in the closed position, and extends from the one end to the center of the passage T. However, the length of the second rail 36 is shorter than that of the first rail 35 and is, for example, about the thickness of the door 1 (the length on the short axis side). The upper bearing portion 32 is provided to be slidable (slidable) along the second rail 36. Then, the bearing member 34 slides on the second rail 36 and comes into contact with and separates from the passage wall, so that the door 1 is rotated and moved back and forth, and the door 1 is rotated and the pair of guide rollers. 24 while allowing it to approach or move away from 24. When the door 1 is in the closed position, the bearing member 34 is located closest to the passage wall. The lower bearing portion 33 corresponds to the first bearing portion in the present invention, and the upper bearing portion 32 corresponds to the second bearing portion in the present invention.

  Furthermore, a compression spring 37 is attached to the approximate center in the longitudinal direction of the door 1. In the second embodiment, the compression spring 37 is provided along the second rail 36. One end of the compression spring 37 abuts on the upper bearing portion 32 (bearing member 34), and the other end of the compression spring 37 is the second rail. It is fixed on 36 axes. As clearly shown in FIGS. 17A and 17B, the compression spring 37 is compressed and deformed as the bearing member 34 is separated from the passage wall. The restoring force generated in the compression spring 37 causes the bearing member 34 to move toward the passage wall. It is urged in the direction close to. That is, it is provided so that a greater restoring force acts on the bearing member 34 when the door 1 is open than when the door 1 closes the passage T. The compression spring 37 corresponds to the elastic body in the present invention.

  Similarly, a holding mechanism 31 and a compression spring 37 attached to the holding mechanism 31 are also provided at the lower end of the door 1. The holding mechanism 31 on the lower end side is accommodated in a position where the upper bearing portion 32 and the second rail 36 are dug down the passage T. In addition, since the upper bearing part 32 and the 2nd rail 36 are a channel | path wall side by planar view, and are arrange | positioned under the door 1, it does not become an obstacle for the to-be-passed object M which passes the channel | path T. FIG.

FIG. 18 to FIG. 21 are stroke diagrams showing the opening / closing operation of the door 1 having such a configuration.
In the passage closed state, as shown in FIG. 18, the door 1 is in a closed position across the passage.

  As shown in FIG. 19, the passing object M pushes the door 1 in the traveling direction and swings the door 1 open. The bearing member 34 slides away from the passage wall according to the opening movement of the door 1, and the compression spring 37 is compressed and deformed according to the sliding of the bearing member 34. The bearing member 34 is urged in a direction approaching the passage wall by the restoring force generated in the compression spring 37 that has been compressed and deformed. In addition, in FIG. 19, the force F which the passing thing M acts on the door 1 is shown typically.

  As shown in FIG. 20, the passing object M further moves the door 1 along the side wall of the passage to the side opposite to the traveling direction. At this time, at least the line connecting the center point between the guide rollers 24 and the rotating body 23 is moved until the center in the longitudinal direction of the door is opposite to the traveling direction. In FIG. 20 also, the force F that the passing object M acts on the door 1 is schematically shown.

  As shown in FIG. 21, when the center of the door longitudinal direction is opposite to the traveling direction with respect to the line connecting the center point between the guide rollers 24 and the rotating body 23, the passing object M is separated from the door 1, A state where no force is applied to the door 1 is set. At this time, the force acting on the door 1 is only the restoring force of the compression spring 37 transmitted through the bearing member 34, and this restoring force works in the direction in which the bearing member 34 approaches the passage wall. The bearing member 34 slides in a direction approaching the passage wall according to the biasing force of the compression spring 37, and the door 1 further moves along the passage side wall in the direction opposite to the traveling direction in accordance with the sliding movement of the bearing member 34. To do. When the other top portion of the door 1 reaches the vicinity of the position of the rotating body 23, the door 1 is rapidly closed and swung forward with the top portion as a center, and quickly closes behind the passage M to close the passage T. (FIG. 21).

  As described above, in the door device G of this example, the compression spring 37 is contracted and deformed in response to the opening movement of the door 1, and the door 1 is closed and swung only by the restoring force stored in the compression spring 37. Therefore, it is possible to save the trouble of the passing object M closing and moving the door 1. Moreover, by providing the compression spring 37, it can be set as a simple structure, without providing separately power sources, such as a motor. Furthermore, since the endless belt 22, the rotating body 23, and the guide roller 24 guide the door 1 that has been opened and moved around the back of the article M to the closed position, the passage of the article M is not hindered.

  FIG. 22 is a perspective view of the door device according to the third embodiment. The door 1 according to the third embodiment has a rectangular shape in plan view. At the upper end of the door 1, convex portions 41 are respectively formed at both end portions in the door longitudinal direction. A support shaft 43 is formed at a substantially central portion in the door longitudinal direction. Each convex portion 41 has a cylindrical shape having an equivalent size. Further, the support shaft 43 protrudes to a position higher than the convex portion 41.

  A rail-like object 45 is installed at a height substantially equal to the upper end of the door 1 on the side wall side of the passage. Inside the rail-like object 45, a groove portion 46 is formed in which the convex portion 41 can slide. Further, a notch 47 for engaging the convex portion 41 with the groove portion 46 in the rail-like object 45 is formed at one end of the rail-like object 45. Further, a locking portion 48 that communicates with the groove portion 46 is formed on the other end side of the rail-like object 45, and the convex portion 41 that slides on the groove portion 46 can be guided to the locking portion 48. The locking part 48 is formed with a notch for releasing the holding by the locking part 48 while locking the convex part 41 rotatably and allowing the convex part 41 to move toward the center of the passage. .

  An arm member 51 is provided at the upper end of the rail-like object 45. The arm member 51 is supported so as to be rotatable around a single axis P concentric with the center of the convex portion 41 held by the locking portion 48. The other end side of the arm member 51 holds the support shaft 43 of the door 1 so as to be freely rotatable. Accordingly, the door 1 is pivotally supported by the arm member 51 so as to be rotatable.

  In addition, a torsion spring 53 is provided at the upper end of the rail-like object 45 so as to contact the arm member 51. The torsion spring 53 is attached to the arm member 51 so that the torsion spring 53 is deformed by the arm member 51 that rotates in response to the open swing of the door 1 and is moved to the position of the arm member 51 corresponding to the door 1 in the closed position. Rush. In the third embodiment, the torsion spring 53 urges the base end portion of the arm member 51 so that the angle formed by the arm member 51 and the side wall of the passage T becomes substantially a right angle. Here, the torsion spring 53 corresponds to the elastic body in the present invention. The rail-like object 45 and the arm member 51 correspond to the guide support mechanism in this invention.

  Next, operation | movement of this door apparatus G is demonstrated based on the flowchart of FIGS.

  FIG. 23 shows a state in which the door device G is closed, and the door 1 is in the closed position. At this time, the convex portion 41 closer to the uniaxial P (hereinafter, appropriately referred to as the convex portion 41 near the uniaxial P) is locked to the locking portion 48.

  In FIG. 24, the passing object M presses the pair of doors 1 in the traveling direction. As a result, the convex portion 41 held by the locking portion 48 rotates around its center (concentric with the one axis P), and the door 1 swings open in the traveling direction of the passage T. At this time, the arm member 51 rotates integrally with the opening swing of the door 1 while deforming the torsion spring 53. At this time, the restoring force of the torsion spring 53 is urged to the arm member 51. When the support shaft 43 comes into contact with the rail-like object 45, the opening and swinging of the door 1 around the one axis P is restricted.

  In FIG. 25, when the passing object M further presses the pair of doors 1 in the traveling direction, the door 1 acts as a rotational force around the support shaft 43. At this time, the convex portion 41 held by the anchoring portion 48 moves toward the center of the passage through the notch formed in the anchoring portion 48, and the holding by the anchoring portion 48 is released. At the same time, the door 1 rotates about the support shaft 43. In the door 1 in such an open position, the convex portion 41 (the convex portion 41 far from the one axis P) formed on the other end side is formed in the groove portion 46 formed in the rail-like object 45 through the notch 47. Engaged.

  In FIG. 26, the passing object M is separated from the door 1 so that no force is applied to the door 1. The force acting on the door 1 is only the restoring force of the torsion spring 53 transmitted through the arm member 51, and this restoring force is applied in the direction of moving to the position of the arm member 51 corresponding to the door 1 in the closed position. It is fast. The arm member 51 rotates around one axis P in accordance with the biasing force of the torsion spring 53. Following this rotation, the door 1 closes and swings so that the support shaft 43 moves on a circular path around the axis P. At this time, the convex portion 41 guided by the groove portion 46 slides along the groove portion 46 according to the closing swing of the door 1. For this reason, the door 1 itself rotates around the support shaft 43 due to the positional relationship between the convex portion 41 sliding on the groove 46 and the support shaft 43. As a result, the door 1 moves to the closed position where the passage T is closed while sliding so as to go around behind the traffic object M (FIG. 26).

  As described above, in the door device G of this example, the torsion spring 53 is pressed by the force F that pushes the door 1 when the passing object M swings the door 1 open, and the restoring force stored in the torsion spring 53 is restored. Only by moving the door 1 back and forth in the direction of the passage, the door 1 is closed and swung. Therefore, it is possible to save the trouble of the passing object M closing and moving the door 1 (including the trouble of moving the door 1 back and forth). Further, by providing the torsion spring 53, a simple configuration can be achieved without separately providing a power source such as a motor. Furthermore, since the rail-like object 45 and the arm member 51 guide the door 1 that has been moved open around the back of the passing object M to the closed position, the passage of the passing object M is not hindered.

  The present invention is not limited to the above-described embodiment, and can be modified as follows.

  (1) In each above-mentioned Example, it is not restricted to this which illustrated the extension spring 13, the compression spring 37, and the torsion spring 53 as an elastic body. That is, other types of elastic bodies may be applied as appropriate. Moreover, you may change so that a well-known mechanism like a door closer may be applied.

  Moreover, although the door apparatus G in Example 1 provided the extension spring 13 for every door 1 on either side, it is not restricted to this. FIG. 27 is a partial front view of a door device according to a modified embodiment. As shown in FIG. 27, the stopper 15 may be omitted, and a single extension spring 13 having both ends locked to each spring support piece 14 provided on the left and right doors 1 may be provided. Good.

  Further, instead of the elastic body, a pulley mechanism may be applied. FIG. 28 is a front view of a door device G according to a modified embodiment. As shown in the drawing, a wire 63 with a weight 61 suspended from one end is hung around a pulley 65 and attached to a substantially central portion of the door 1 in the longitudinal direction of the door. As the position of the pulley 65, the front end side in the door longitudinal direction of the door 1 at the closed position is preferable. With this configuration, the door 1 can always be urged toward the closed position by the gravity acting on the weight 61. Thereby, the trouble of the passing thing M closing and moving the door 1 can be saved. The weight 61, the wire 63, and the pulley 65 correspond to the pulley mechanism in the present invention.

  (2) In the first embodiment described above, the guide rail 4 is not limited to the shape described above, and may be formed in a flat oval shape in which, for example, arc portions at both ends are connected by straight portions.

  (3) Although the door apparatus G in Example 1 mentioned above was provided with the guide rails 4 and 8 in the upper and lower ends of the door 1, it is not restricted to this. For example, the guide rail 4 may be changed only at the upper end, or the guide rail 8 may be changed only at the lower end.

  (4) Although the door device G in the first embodiment described above has the extension spring 13 attached only to the upper end of the door 1, it is not limited thereto. For example, the extension spring 13 may be attached only to the lower end of the door 1, or the extension spring 13 may be attached to the upper and lower ends of the door 1, respectively.

  (5) Although the structure in which the tooth portion 26 is formed on the entire outer periphery of the guide portion 21 is shown in the above-described second embodiment, the present invention is not limited to this. For example, as shown in FIG. 29, the tooth portion 26 is formed only in a gently convex region close to the straight line of the door 1 in plan view (in other words, a region having a large curvature that curves in the long axis direction of the door 1). Also good. Even if the tooth portion is provided near the top (near the end) of the small curvature, the tooth portion 25 of the endless belt 22 is not sufficiently engaged, and slippage is likely to occur. Therefore, by configuring as in the above modification, the tooth portion 26 can be formed only in a range in which the endless belt 22 and the guide portion 21 are reliably transmitted.

  (6) Although the toothed belt is illustrated as the endless belt 22 in the above-described second embodiment, the present invention is not limited thereto. Various known belts and various chains may be employed as appropriate.

  (7) In the door device G in the above-described second embodiment, the guide portion 21 is provided at the upper end and the lower end of the door 1, and the endless belt 22, the rotating body 23, and the guide roller 24 are provided in each guide portion 21. However, it is not limited to this. For example, you may provide the guide part 21 only in the upper end of the door 1, or only in a lower end.

  (8) In the first and second embodiments described above, the guide members 6, 7, 9, 10 or the rotation fulcrum of the rotating body 23 provided in a freely rotatable manner are elastically rearward in the opening direction by an external force. It is also possible to provide the accommodation that can move backward or maintain a suitable torque and can move backward, and can be configured to exhibit a buffering function when a passing object collides with the door 1.

  (9) In Example 1 described above, when the center in the longitudinal direction of the door is opposite to the traveling direction with respect to the contact point between the guide members 6 and 7 and the guide rail 4, the passing object M is separated from the door 1, Although no force is applied to the door 1, it is not limited to this. If the door 1 can be moved to the closed position by the restoring force of the extension spring 13, the position where the passing object M moves away from the door 1 and does not apply any force to the door 1 can be appropriately selected and changed. it can. Similarly, in the above-described second embodiment, when the center in the longitudinal direction of the door is opposite to the traveling direction with respect to the line connecting the center point between the guide rollers 24 and the rotating body 23, the passing object M is separated from the door 1. It is in a state where no force is applied to the door 1, but this is not restrictive. If the door 1 can be moved to the closed position by the restoring force of the compression spring 37, the position where the passing object M leaves the door 1 and does not apply any force to the door 1 can be appropriately selected and changed. it can.

  (10) In the door device G in the above-described third embodiment, the arm member 51 is supported by the rail-like object 45, but is not limited thereto. For example, you may change so that the arm member 51 may be supported by the channel | path wall etc., or may be supported by the thing corresponded to the upper frame 2 demonstrated in Example 1. FIG. Also, the fixing position of the torsion spring 53 can be appropriately changed in design according to the support method of the arm member 51.

  (11) In the door device G in the above-described third embodiment, the door 1 has a rectangular shape in plan view, but is not limited thereto. For example, an elliptical shape may be exhibited as in the first and second embodiments.

  (12) In the door device G in the above-described third embodiment, the convex portion 41 and the support shaft 43 are formed at the upper end of the door 1, and the rail-like object 45 and the arm member 51 are arranged on the side wall side of the passage. However, it is not limited to this. For example, you may change so that the said convex part 41 and the support shaft 43 may be formed only in the upper-lower end or lower end side of the door 1. FIG. Correspondingly, the rail-like object 45 and the arm member 51 may be changed so as to be arranged on the upper and lower sides of the passage side wall or only on the lower side.

  (13) Although the door device G of each of the embodiments described above includes the two doors 1, it is not limited to this configuration. For example, the door device G may have a configuration including only a single door 1 (see FIG. 28) or a configuration including three or more doors 1 in a horizontal row. In addition, even if the door apparatus G is the structure provided with only the single door 1, it can comprise so that the channel | path T may be opened and closed.

  (14) In each of the above-described embodiments, a mechanism for holding the door 1 in the closed position may be provided.

Inside the door 1 covered with the plate portion 71, an engagement shaft 73 configured by connecting three rod-like objects so as to be bendable with each other is accommodated and arranged. The front end of the engagement shaft 73 penetrates the side end of the door 1 and protrudes outward. In addition, an engagement groove 77 is formed in the vertical frame 75 disposed on the side of the door 1 at a position facing the tip of the engagement shaft 73. As shown in FIG. 31A, when the door 1 is in the closed position, the tip of the engagement shaft 73 that extends in a straight line is fitted in the engagement groove 77. Here, when the door 1 is moved open, the passing object M first presses the plate portion 71. Thereby, as shown in FIG. 31B, the plate portion 71 is bent so as to bend toward the inner side of the door 1, and the engagement shaft 73 is bent by the bent plate portion 71. As a result, the tip of the engagement shaft 73 is disengaged from the engagement groove 77. Thereby, holding | maintenance of the door 1 in the obstruction | occlusion position is cancelled | released. Subsequently, when the door 1 is pressed, the door 1 swings in a series of open positions. By comprising in this way, when the passing thing M does not pass the door apparatus G, the door 1 can be hold | maintained in the obstruction | occlusion position. Moreover, since the said holding | maintenance can be cancelled | released only by pressing the door 1 when the passage thing M passes, the effort of the passage thing M is not taken.
