<Overall structure of side-opening door>
As shown in Figs. 1 to 3, the side-opening door 12 having the smoke-blocking structure according to this embodiment is configured as an automatic door, and the automatic door 12 is provided at the entrance 1. Specifically, a three-sided frame 2 and a threshold 3 are fixed to the opening of the body 1A of the entrance 1, and a plurality of doors are installed on the three-sided frame 2 and the threshold 3 along the door width direction W so as to be able to be opened and closed from one side to the other. In this embodiment, the number of doors is three. The three-sided frame 2 includes an upper frame 21 extending along the door width direction W at the upper part of the door height direction H, and a pair of vertical frames 22 connected to both ends of the upper frame 21 in the door width direction W and extending along the door height direction H. A threshold 3 is provided below the door height direction H of the three-sided frame 2, which is connected to the pair of vertical frames 22 and extends along the door width direction W. As a result, the opening of the entrance 1 is closed by the three-sided frame 2, the threshold 3, and the three doors. Here, the automatic door 12 is an example of a side-opening door.

The automatic door 12 is provided with a drive unit 50 that opens and closes the door along the door width direction W, located on the door depth direction D side of the frame 2 and on the rear surface of the body 1A. As shown in FIG. 2, the drive unit 50 has structures 52 that are raised along the door height direction H on both sides of the door width direction W on the outer periphery of the frame 2, and three rails 54 (see FIG. 4) corresponding to the three doors are provided on the upper part of the structure 52 along the door width direction W, and each door is hung from each rail 54.

[door]
As shown in Fig. 1, the side-opening door is described as a three-leaf side-opening door in this embodiment, and a first door 41, a second door 42, and a third door 43 are provided in the door width direction W. The door width direction W is the closing direction of the side-opening door 12, and the direction facing the opposite direction is the opening direction of the side-opening door 12. When the doors are opened, the three doors open and close in the horizontal direction so as to be hidden by the left side of the vertical frame 22 on the opposite side of the door width direction W. The opening and closing speed of the first door 41 is low, the second door 42 is medium, and the third door 43 is high, and they open and close synchronously.

The upper roller 48 is rotatably supported on the upper surface of the rail 54, and supports the door so that it can be hung so that it can be opened and closed laterally. The lower roller 48 contacts the lower surface of the rail 54 to suppress the vertical movement of the door in the door height direction H.

[Three-sided frame]
The pair of vertical frames 22 of the three-sided frame 2 are narrowed toward the door depth direction D on the first door 41 side in the door width direction W and widened toward the door depth direction D on the third door 43 side in accordance with the opening and closing positions of the three doors shown in Fig. 3. The upper frame 21 of the three-sided frame, although not shown, is formed in a stepped shape when viewed from the door height direction H in accordance with the opening and closing positions of the three doors. In other words, it is formed in a stepped shape to match the step formed between the end side of the first door 41 in the door width direction W and the end side of the second door 42 in the door width direction W. The same applies to the upper frame 21 of the three-sided frame 2 for the second door 42 and the third door 43.

As shown in FIG. 5, the end of the upper frame 21 of the jamb 2 in the door depth direction D has a raised portion 211 bent toward the door height direction H. The upper frame 21 has two mounting members 23 and a three-sided frame airtight portion 24 sandwiched between these mounting members 23 and fixed to the structure 52 of the automatic door 12, making the inside and outside of the entrance 1 in the door depth direction D of the jamb 2 airtight. The side of the upper frame 21 facing the main body 1A is closed by a finishing member 25 that fills the gap between the upper frame 21 and the main body 1A, and this finishing member 25 also creates an airtight state between the jamb 2 and the main body 1A. This finishing member 25 also creates an airtight state between the vertical frame 22 and the main body 1A.

As a result, when the first door 41 is closed along the door width direction W to be in a closed state, the surface of the end side 45A of the first door 41 is in close contact with the silicon plate 102. When the surface of the end side 45A of the first door 41 is in close contact with the silicon plate 102, the surface of the end side 45A of the second door 41 is also in close contact with the silicon plate 102 for the second door 42 at the same time. At this time, the first door 41 to the third door 43 are in close contact with each synthetic resin plate 63 provided on the rising portion 211 in the upper frame 22 of the three-sided frame 2, so that all the upper ends of each door are in an airtight state.

The silicone rubber packing 82 or 92 used in the third airtight section to the fifth airtight section is shown in FIG. 15. Since the silicone rubber packing 82 or 92 has the same structure, only the silicone rubber packing 82 will be described here.

As shown in FIG. 15, the silicone rubber packing 82 includes a base portion 82A that is attached to the bracket, a straight portion 82B, and a contact portion 82C. The silicone rubber packing 82 is flexible overall, and is designed to bend along the door width direction W when pressure is applied in the door width direction W. The silicone rubber packing 82 has multiple holes (not shown) spaced apart along the door height direction H so that the base portion 82A can be fixed with a bolt.

<Function of main parts>
Next, the operation of the first airtight portion to the fifth airtight portion will be described.

[Function of the first airtight portion]
As shown in Figs. 7 and 8, in the first airtight section 6, a synthetic resin plate 63 provided on the rising portion 211 of the frame 2 via a leaf spring 62 is biased against the surface 45 of the first door 41 or the airtight plate 61 and is in close contact with the surface 45 of the first door 41. This state is the same for the second door 42 and the third door 43. When each door starts to close in the door width direction W, the synthetic resin plate 63 slides against the surface of each airtight plate 61 or the surface 45 of each door of the first door 41, the second door 42, and the third door 43 and comes into close contact with them. When each door is in a closed state, the synthetic resin plate 63 and the surface of each airtight plate 61 or the surface 45 of each door are in close contact with each other over the entire area of the door width direction W. As a result, the upper ends of the first door 41, the second door 42, and the third door 43 are maintained in an airtight state.

[Function of the second airtight portion]
As shown in Figs. 9 and 10, the second airtight section 7 is in close contact with the synthetic resin plate 72 provided on the inner surface 45B of the first door 41 that opens downward via a leaf spring 71, which is biased against the airtight rail 74 fixed to the surface facing upward of the threshold 3. This state is similar for the second door 42 and the third door 43. When each door starts to close in the door width direction W, the synthetic resin plate 72 comes into close contact with the surface of the airtight rail 74 that faces the door depth direction D while sliding. When each door is in a closed state, the synthetic resin plate 72 provided on each door and the surface of the airtight rail 74 provided corresponding to each door come into close contact over the entire area of the door width direction W. As a result, the lower ends of the first door 41, the second door 42, and the third door 43 are maintained in an airtight state.

[Function of the third airtight portion]
As shown in Fig. 11, the third airtight section 8 is formed by a silicone rubber packing 82 provided inside the end side 45A on the side of the door width direction W of the first door 41 facing the opposite side of the door width direction W, and a bracket 83 fixed to the end side 45A on the opposite side of the door width direction W of the second door 42 and having an airtight surface 84 that contacts the silicone rubber packing 82, which are in close contact with each other when the doors are closed. This state is similar in the relationship between the second door 42 and the third door 43. When each door starts to close in the door width direction W, the airtight surface 84 of the bracket 83 provided on the second door 42 approaches toward the silicone rubber packing 82 of the first door 41. When each door is in a closed state, the silicone rubber packing 82 provided on the first door 41 and the airtight surface 84 provided on the second door 42 are in close contact with each other. This maintains the end sides 45A of the first door 41 and the second door 42, or the second door 42 and the third door 43 in an airtight state.

[Function of the fourth airtight portion]
As shown in Figures 12 and 13, the fourth airtight section 9 is provided in two locations: between the first door 41 and the vertical frame 22 on the first door 41 side of the frame 2, and between the third door 43 and the vertical frame 22 on the third door 41 side of the frame 2.

(Fourth airtight section between the first door and the vertical frame 22)
As shown in Fig. 12, between the first door 41 and the vertical frame 22 on the first door 41 side of the three-sided jamb 2, the silicone rubber packing 92 fixed to the surface facing the opposite side in the door width direction W of the bracket 91 fixed inside the vertical frame 22 and the airtight surface 94 of the bracket 93 fixed to the end side 45A on the opposite side of the door width direction W of the first door 41 are in airtight contact with each other in the door closed state. When each door starts to close in the door width direction W, the airtight surface 94 of the bracket 93 provided on the first door 41 approaches the silicone rubber packing 92 provided on the vertical frame 22 on the first door 41 side. When each door is in the closed state, the silicone rubber packing 82 provided on the vertical frame 22 and the airtight surface 94 of the bracket 93 provided on the first door 41 are in airtight contact with each other. As a result, the first door 41 and the vertical frame 22 on the first door 41 side are maintained in an airtight state.

(Fourth airtight section between the third door and the vertical frame 22)
As shown in Fig. 13, between the third door 43 and the vertical frame 22 on the third door 43 side of the three-sided frame 2, the silicone rubber packing 92 fixed to the surface facing the opposite side in the door width direction W of the bracket 91 fixed to the door depth direction D side of the vertical frame 22 and the airtight surface 93 of the end side 45A on the door width direction W side of the third door 43 are in airtight contact with each other in the door closed state. When each door starts to close in the door width direction W, the airtight surface 93 of the third door 43 approaches the silicone rubber packing 92 provided on the vertical frame 22 on the third door 43 side. When each door is in the closed state, the silicone rubber packing 92 provided on the vertical frame 22 and the airtight surface 93 of the third door 43 are in airtight contact with each other. As a result, the third door 43 and the vertical frame 22 on the third door 43 side are maintained in an airtight state.

[Function of the fifth airtight portion]
As shown in FIG. 14, the fifth airtight section is formed in a step-like shape in a plan view along the surface 45 of each of the first door 41 and the second door 42, and the opposing plate 101 is provided in a direction along the door depth direction D so as to connect the respective rising portions 211, and the airtight surface 103 of the silicon plate 102 fixed to the surface facing the opposite side of the door width direction W of the opposing plate 101 and the surface of the end side 45A of the first door 41 on the door width direction W side are in airtight contact. When each door starts to close toward the door width direction W, the surface of the end side 45A of the first door 41 approaches toward the airtight surface 103 of the silicon plate 102 on the first door 41 side. When each door is in a closed state, the airtight surface 103 of the silicon plate 102 provided on the opposing plate 101 and the surface of the end side 45A of the first door 41 are in airtight contact. As a result, the first door 41 and the opposing plate 101 are maintained in an airtight state. Similarly, on the end side 45A of the second door 42 in the door width direction W, the airtight surface 103 of the silicon plate 102 provided on the opposing plate 101 and the surface of the end side 45A of the second door 42 are in airtight contact with each other.

As described above in detail, the side-opening door with a smoke-tight structure according to this embodiment has an airtight state between the jamb 2 and the door, between the threshold 3 and the door, and between the doors themselves, due to the structure and action of the first airtight section to the fifth airtight section, which prevents smoke from a fire from leaking out of the entrance/exit 1. In addition, the release of fluorocarbons or carbon dioxide due to a fire is also prevented from leaking out of the entrance/exit 1.

In this way, the side-opening door 12 with a smoke-tight structure according to this embodiment is a side-opening door with a smoke-tight structure on at least two doors that can be opened and closed horizontally relative to the jamb 2 and the threshold 3, and has a first airtight section 6 that seals the gap between the upper parts of the doors 41, 42, 43 and the upper frame 21 of the jamb 2, a second airtight section 7 that seals the gap between the lower parts of the doors 41, 42, 43 and the threshold 3, a third airtight section 8 that seals the gap between the ends of the gable sides 45A of the doors 41, 42, 43, a fourth airtight section 9 that seals the gap between the ends of the gable sides 45A of the doors 41, 42, 43 and the vertical frame 22 of the jamb 2, and a fifth airtight section 10 that seals the gap between the ends of the gable sides 45A of the doors 41, 42, 43 and the upper frame 21 of the jamb 2.

As a result, the airtightness of the side-opening door 12 is ensured and a smoke-blocking effect is achieved by simply closing the doors 41, 42, and 43, compared to when the door is moved and pressed against the frame on three sides.

The first airtight section 6 is also configured to include a leaf spring 62 that is fixed to the upper frame 21 facing the surface 45 of the doors 41, 42, and 43 and biases the doors 41, 42, and 43, and a synthetic resin plate 63 that is fixed to the free end of the leaf spring 62 and contacts the surface 45 of the doors 41, 42, and 43.

As a result, the upper part of the side-opening door 12 is kept airtight by simply closing the doors 41, 42, and 43, and a smoke-blocking effect is achieved, compared to when the door is moved and pressed against the frame on three sides.

The second airtight section 7 is composed of an airtight rail 74 fixed along the opening and closing direction of the doors 41, 42, and 43 of the threshold 3, a leaf spring 71 fixed to the lower part of the doors 41, 42, and 43 and biasing them toward the airtight rail 74, and a synthetic resin plate 72 fixed to the free end of the leaf spring 71 and in contact with the airtight rail 74.

As a result, the bottom of the side-opening door 12 is kept airtight by simply closing the doors 41, 42, and 43, compared to when the door is moved and pressed against the frame on three sides, and a smoke-blocking effect is achieved.

The third airtight section 8 is located inside one of the doors 41 or 42 and includes a silicone rubber packing 82 facing the opening direction of the other door 42 or 43, and an airtight plate 83B that is fixed to the end of the end side 45A of the other door 42 or 43 and contacts the silicone rubber packing 82. When the doors 41, 42, and 43 are closed, the silicone rubber packing 82 and the airtight plate 83B come into contact.

As a result, compared to moving the doors and pressing them against the frame on three sides, simply closing the doors 41, 42, and 43 ensures airtightness between the doors of the side-opening door 12, providing a smoke-blocking effect.

The fourth airtight section 9 is composed of a silicone rubber packing 92 fixed to one of the vertical frames 22 facing the closing direction of the door 41, and an airtight material 93B fixed to the end side 45A facing the opening direction of the door 41 and facing the closing direction of the door 41, and when the door 41 is closed, the silicone rubber packing 92 and the airtight material 93B come into contact.

As a result, compared to moving the door and pressing it against the frame, simply closing the doors 41, 42, and 43 ensures airtightness between the door 41 at one end of the side-opening door 12 and the vertical frame 22 of the frame 2, providing a smoke-blocking effect.

It also includes a silicone rubber packing 92 that is fixed to one vertical frame 22 and the other vertical frame 22 on the opposite side facing the opening direction of the door 43, and a surface 93 at the end of the gable side 45A that faces the closing direction of the door 43. When the door 43 is closed, the silicone rubber packing 92 and the surface 93 at the end of the gable side 45A come into contact.

As a result, compared to moving the door and pressing it against the frame on three sides, simply closing the doors 41, 42, and 43 ensures airtightness between the door 43 at the other end of the side-opening door 12 and the vertical frame 22 of the frame 2, providing a smoke-blocking effect.

The fifth airtight section 10 is composed of an opposing plate 101 fixed to a position facing the end of one of the end sides 45A of the door 41 or 42 in the upper frame 21 of the three-sided frame 2, and a silicon plate 102 fixed facing the surface of the end of the end side 45A of the door 41 or 42 on the opposing plate 101, and when the door 41 or 42 is closed, the silicon plate 102 comes into contact with the surface of the end of one of the end sides 45A of the door 41 or 42.

As a result, compared to moving the door and pressing it against the jamb on three sides, the airtightness of the end of the side-opening door 12 facing the opening direction of door 41 or 42 is ensured by simply closing doors 41, 42, and 43, and a smoke-blocking effect is achieved.

The mechanical parking device also includes a boarding/de-boarding room where the vehicle moves in and out, a storage room where the vehicle moves between the boarding/de-boarding room, and a side-opening door 12 having a smoke-blocking structure described in any one of the first to seventh aspects, which is installed at the entrance/exit of the boarding/de-boarding room.

This ensures that the entrance doors to the boarding and disembarking compartments through which vehicles move in and out are airtight, providing a smoke-blocking effect. In addition, even if a fire extinguishing system is activated in the compartment in which the mechanical parking device is installed and fluorocarbons or carbon dioxide are released, leakage of the fluorocarbons or carbon dioxide from the entrance doors is suppressed.

The above describes one embodiment of the present invention, but this embodiment is merely an example, and various modifications can be made without departing from the spirit of the present invention. It goes without saying that the scope of the present invention is not limited to these embodiments.
