(Configuration - Details of the configuration of the second opening/closing body)
Returning to FIG. 1, next, details of the configuration of the second opening/closing body 50 will be described. However, the second opening/closing body 50 can be manufactured in any shape, method, and material, unless otherwise specified.

(Configuration - Details of the configuration of the second opening/closing body - First feature)
First, regarding the first feature of the configuration of the second opening/closing body 50, the second opening/closing body 50 slides relative to the frame 10 as the first opening/closing body 30 slides, and the first opening/closing body 50 slides relative to the frame 10. 30, when the second opening/closing body 50 comes into contact with an obstacle B (e.g., a person, an animal, or an object) that exists on either side of the opening 3 in the expected direction. The first opening/closing body 30 is configured to be able to rotate without interfering with the sliding movement of the first opening/closing body 30 by contacting the first opening/closing body 30.

Specifically, the second opening/closing body 50 functions as a door body for a swinging door (in FIG. 1, a door body for a single-opening type swinging door that can be opened toward the indoor side and the outdoor side of the room). It is configured. More specifically, as shown in FIG. 1, FIG. 2, and FIG. It is one door body consisting of a surface material 53 and a second core material 54, and is rotatably supported with respect to the first opening/closing body 30 by an upper second hinge part 62a and a lower second hinge part 62b. It is constructed as a door body.

In addition, regarding the method of connecting the second opening/closing body 50 to each of the upper second hinge part 62a and the lower second hinge part 62b, the upper second hinge part 62a of the second opening/closing body frame 51 is The part near the end of the lateral force bone 51c on the door end side is connected to the upper horizontal part 31e of the lower first lateral force bone 31d in the door end side first opening/closing body 30b, and the lower second Via the hinge portion 62b, the lower second lateral force bone 51d of the second opening/closing body frame 51 is connected to a portion near the end on the door end side and the lower first lateral force bone 31d of the first opening/closing body main body 30b on the door end side. It is connected to the lower horizontal portion 31f of. Further, when the second opening/closing body 50 and the obstacle B come into contact with each other, when the second opening/closing body is pressed by the obstacle B with a force greater than a predetermined amount, the second opening/closing body is connected so as to rotate. ing. Note that this "predetermined amount" is determined, for example, from the viewpoint of usability of the second opening/closing body 50, so that the sliding movement of the first opening/closing body 30 is not hindered, and the second opening/closing body 30 is not prevented from sliding while the first opening/closing body 30 is sliding. It is desirable to set the amount to such an extent that the second opening/closing body 50 does not rotate when there is no contact between the body 50 and the obstacle B, and for example, it may be set based on experimental results or the like.

Furthermore, regarding the opening degree of the second opening/closing body 50 (specifically, the opening degree from the second fully closed state to the second fully open state), for example, if an obstacle B exists near the opening 3, In such a case, it is desirable to set the opening degree so that the first opening/closing body 30 can be slid to the first fully open position, and for example, it may be set to 90 degrees or more. However, the angle is not limited to this, and may be set to less than 90 degrees, for example.

Due to this first feature, as shown in FIG. 6, when an obstacle B exists on either side of the opening 3 in the direction of view (in FIG. 6, the obstacle B is on the indoor side of the room). ), when sliding the first opening/closing body 30, the second opening/closing body 50 is moved so that even if the second opening/closing body 50 comes into contact with the obstacle B, the sliding movement of the first opening/closing body 30 is not hindered. It can be rotated (the same applies when the obstacle B exists on the outside of the room). Therefore, compared to the case where the second opening/closing body 50 is not provided, the first opening/closing body 30 can be reliably slid and the usability of the opening/closing body 20 can be improved. Moreover, since the second opening/closing body 50 is a door body for a swinging door, when sliding the first opening/closing body 30, compared to a door body for a folding door, for example, the sliding movement of the first opening/closing body 30 is Since the second opening/closing body 50 can be easily rotated without being obstructed, usability of the opening/closing body 20 can be easily improved.

(Configuration - Details of configuration of second opening/closing body - Second feature)
Returning to FIG. 1, the second feature of the configuration of the second opening/closing body 50 is as shown in FIGS. 1 and 5. and is provided in the lower part of the first opening/closing body 30.

It is provided in the corresponding part.

With such a second feature, as shown in FIG. 50 is provided on the door end side of the first opening/closing body 30, the second opening/closing body 50 is brought into contact with the obstacle B sooner so that the sliding movement of the first opening/closing body 30 is not obstructed. The body 50 can be rotated, making it easier to slide the first opening/closing body 30. Further, when an obstacle B exists on the floor surface 4 near the opening 3, the second opening/closing body 50 is surely brought into contact with the obstacle B so that the sliding movement of the first opening/closing body 30 is not obstructed. The second opening/closing body 50 can be rotated, making it easier to slide the first opening/closing body 30.

(Configuration - Details of configuration of second opening/closing body - Third feature)
Returning to FIG. 1, regarding the third feature of the configuration of the second opening/closing body 50, the upper second hinge portion 62a and the lower second hinge portion 62b are connected to the shaft portion 42a of the door roller portion 42 when viewed from the forward direction. (A shaft-like body that connects the main body of the door roller part 42 and the first opening/closing body 30. Hereinafter referred to as the "door roller side shaft part 42a") It is arranged at a position on the same straight line as the portion 42a.

Specifically, as shown in FIGS. 1 and 5, as described above, the second indoor surface material 53 is configured to be flush with the first indoor surface material 33, and the door roller The side shaft portion 42a is disposed approximately at the center in the left-right direction of the upper end portion (specifically, the upper surface of the upper first transverse force bone 31c) of the first door opening/closing body main body 30b. The shaft portions of the upper second hinge portion 62a and the lower second hinge portion 62b are arranged with the door roller side shaft portion 42a on the same straight line (not shown) along the vertical direction when viewed from the forward direction. has been done. More specifically, the upper second hinge portion 62a and the lower second hinge portion 62b are arranged so that the positions in the left-right direction of the respective shaft portions of the upper second hinge portion 62a and the lower second hinge portion 62b match the positions in the left-right direction of the door roller side shaft portion 42a. The second hinge portion 62a and the second lower hinge portion 62b are arranged.

Due to such a third feature, as shown in FIG. 50 corresponding to the second hinge part 62 (upper second hinge part 62a and lower second hinge part 62b) does not enter the obstacle B side and moves along the left-right direction (especially in FIG. (b) to (d)), it is possible to avoid the sliding movement of the first opening/closing body 30 being inhibited by the contact between the portion of the second opening/closing body 50 corresponding to the second hinge portion 62 and the obstacle B. , it becomes easier to slide the first opening/closing body 30. In particular, even when the obstacle B in FIG. 6 is present in close proximity to the first opening/closing body 30, it is possible to slide the first opening/closing body 30. In addition, in the embodiment, "a portion of the second opening/closing body 50 corresponding to the second hinge section 62" refers to a portion of the second opening/closing body 50 that overlaps with the second hinge section 62 when viewed from the plane direction. This section will be described as a portion or a portion near it (specifically, the second outdoor surface material 52 or the second indoor surface material 53 located on the obstacle B side).

For example, as shown in FIG. 7, the upper second hinge part 62a and the lower second hinge part 62b are arranged at a position closer to the door end side of the first opening/closing body 30 than the door roller part 42 when viewed from the forward direction. (Specifically, when the upper second hinge part 62a and the lower second hinge part 62b are arranged closer to the door end side than the door wheel side shaft part 42a), the first Even if the opening/closing body 30 slides, the portion of the second opening/closing body 50 corresponding to the second hinge portion 62 does not enter the obstacle B side, and moves so as to be located on the outside of the room relative to the opening 3. (See especially FIGS. 7(b) to 7(d)), the sliding movement of the first opening/closing body 30 is caused by the contact between the portion of the second opening/closing body 50 corresponding to the second hinge portion 62 and the obstacle B. Obstruction can be avoided, and the first opening/closing body 30 can be slid more easily. In particular, even when the obstacle B in FIG. 7 is present in close proximity to the first opening/closing body 30, it is possible to slide the first opening/closing body 30.

On the other hand, as shown in FIG. 8, the upper second hinge part 62a and the lower second hinge part 62b are arranged at a position closer to the door end of the first opening/closing body 30 than the door roller part 42 when viewed from the forward direction. (Specifically, when the upper second hinge part 62a and the lower second hinge part 62b are arranged closer to the door end side than the door wheel side shaft part 42a), the first opening/closing When the body 30 slides, the part of the second opening/closing body 50 corresponding to the second hinge part 62 enters the obstacle B side, so that the part of the second opening/closing body 50 corresponding to the second hinge part 62 and the obstacle B The sliding movement of the first opening/closing body 30 is inhibited by the contact with the first opening/closing body 30. However, if the obstacle B is located on the indoor side of the room relative to the locus of movement of the portion of the second opening/closing body 50 corresponding to the second hinge part 62 when the first opening/closing body 30 slides, the obstacle Since it is possible to avoid contact between B and the end of the second opening/closing body 50 on the door end side, the sliding movement can be performed.

(Configuration - Details of configuration of second opening/closing body - Fourth feature)
Returning to FIG. 1, next, regarding the fourth feature of the configuration of the second opening/closing body 50, the second opening/closing body 50 is provided with a switching section 70.

(Configuration - Details of the configuration of the second opening/closing body - Fourth feature - Switching part)
The switching unit 70 changes the rotational state of the second opening/closing body 50 into a state in which rotation of the second opening/closing body 50 is permitted (hereinafter referred to as a “rotation permissible state”) and a rotational state of the second opening/closing body 50. A switching means is provided for switching to a state in which the rotation is restricted (hereinafter referred to as a "rotation restriction state"). The switching unit 70 is configured using, for example, a known locking device (for example, a French lock), and is provided on the door end side of the second opening/closing body 50, as shown in FIG. It includes a main body (not shown) and an operation section 71.

The switching unit main body is the basic structure of the switching unit 70 and is provided inside the second opening/closing body 50. Further, this switching section main body is configured using, for example, a lock section of a known locking device, etc. Specifically, when the switching section main body is moved upward by operation of the operating section 71, the upper end of the switching section main body The opening/closing section is configured to be able to be inserted into an insertion section (not shown) provided in the first opening/closing body main body 30b on the door end side.

The operating section 71 is for operating the switching section main body. This operating section 71 is configured using, for example, an operating section of a known locking device, and specifically, by operating the operating section 71 upward, the rotational state of the second opening/closing body 50 can be changed. By switching to the restricted state and operating the operating section 71 downward, the rotational state of the second opening/closing body 50 can be switched to the rotational permission state, and the rotational state after the switching can be maintained. It is configured as follows. Further, as shown in FIG. 1, the operating section 71 is provided on the outdoor side of the room of the second opening/closing body 50, and is connected to the switching section main body by a fixture or the like.

With such a fourth feature, the rotational state of the second opening/closing body 50 can be switched between the rotational permission state and the rotational restriction state. Therefore, for example, when there is no obstacle B in the vicinity of the opening 3, the rotational state of the second opening/closing body 50 is switched to the rotation restriction state, thereby preventing the second opening/closing body 50 from being accidentally opened by the object passing through. The first opening/closing body 30 can be reliably slid by preventing the operation, or by switching the rotation state of the second opening/closing body 50 to the rotation allowing state when the obstacle B exists, and the situation It becomes possible to use the opening/closing body 20 according to the situation.

(Folding door action)
Next, the function of the folding door 1 will be explained. The effect of this folding door 1 is greatly affected by the effect when the obstacle B is located on the indoor side of the room rather than the opening 3, and the effect when the obstacle B is located on the indoor side of the room than the opening 3. Although they are separated, these effects are substantially the same, so below, only the effects when the obstacle B is located closer to the indoor side of the room than the opening 3 will be explained. Note that this action is based on the premise that the opening/closing state of the opening 3 is in the fully closed state, and the rotation state of the second opening/closing body 50 is in the rotation restricted state, as shown in FIG. 6(a). If object B, a person, falls on the indoor side of the room rather than the opening 3, the administrator who is on the outdoor side of the room rather than the opening 3 opens the first opening/closing body 30 in order to rescue the person. The explanation will be made assuming that the opening operation is performed.

First, when the opening operation of the first opening/closing body 30 is performed after the rotation state of the second opening/closing body 50 is switched to the rotation permissible state by the administrator via the operation unit 71 of the switching unit 70, the second opening/closing body 50 is opened. The first opening/closing body 30 and the second opening/closing body 50 slide relative to the frame 10.

Next, when the second opening/closing body 50 (specifically, the door end side portion of the second opening/closing body 50) comes into contact with the person while the first opening/closing body 30 is being opened, 6(b), while the second opening/closing body 50 rotates, the first opening/closing body 30 and the second opening/closing body 50 continue to slide.

Next, when the opening operation of the first opening/closing body 30 is further advanced, the second opening/closing body 50 rotates so that the opening degree of the second opening/closing body 50 becomes larger, as shown in FIGS. 6(c) to (d). However, the sliding movement of the first opening/closing body 30 and the second opening/closing body 50 continues until they are fully opened.

Due to this action, even if the second opening/closing body 50 comes into contact with a person, the second opening/closing body 50 can be rotated so as not to hinder the sliding movement of the first opening/closing body 30, and the first opening/closing body 30 can be rotated. It can be slid reliably. Therefore, for example, the rescue work for the above-mentioned person can be carried out reliably.

For example, if the first opening/closing body 30 is opened and then the first opening/closing body 30 is closed while the person is in a fallen state, the second opening/closing body 50 is closed to the person. The first opening/closing body 30 and the second opening/closing body 50 can slide relative to the frame 10 while the second opening/closing body 50 rotates due to contact with the frame body 10, so the sliding movement is performed until the fully closed state is reached. be able to.

(Effects of embodiment)
According to the embodiment, the first opening/closing body 30 is rotatably supported on the frame 10 provided at the periphery of the opening 3, and the first opening/closing body 30 is slidable relative to the frame 10. The first opening/closing body 30 opens and closes the opening 3 by doing so, and the second opening/closing body 50 is rotatably attached to the first opening/closing body 30. Accordingly, when the first opening/closing body 30 slides with respect to the frame 10, the obstacle B existing on either side of the opening 3 in the viewing direction and the second opening/closing body 30 are moved. The second opening/closing body 50 is provided with a second opening/closing body 50 that can be rotated so as not to hinder the sliding movement of the first opening/closing body 30 due to contact with the body 50. When sliding the first opening/closing body 30, the second opening/closing body 50 can be rotated so as not to prevent the sliding movement of the first opening/closing body 30 even if the second opening/closing body 50 comes into contact with the obstacle B. can. Therefore, compared to the case where the second opening/closing body 50 is not provided, the first opening/closing body 30 can be reliably slid and the usability of the opening/closing body 20 can be improved.

Further, the first opening/closing body 30 is capable of sliding so that the end of the first opening/closing body 30 on the door side approaches the obstacle B when opening the opening 3; Since the opening/closing body 50 is provided on the door end side portion of the first opening/closing body 30, when the first opening/closing body 30 slides so that the door end side portion of the first opening/closing body 30 approaches the obstacle B, Compared to the case where the second opening/closing body 50 is provided on the door end side of the first opening/closing body 30, the second opening/closing body 50 is brought into contact with the obstacle B more quickly so that the sliding movement of the first opening/closing body 30 is not obstructed. The second opening/closing body 50 can be rotated, and the first opening/closing body 30 can be easily slid.
