[0014] [Overall structure of Door 10] The overall configuration of a door 10, which is one embodiment of a large door according to the present invention, will be described below with reference to Figures 1 to 4. In this embodiment, the direction of the door 10 is defined as viewed from the front as shown in Figure 1. That is, the right side in Figure 1 is the right side of the door 10, and the front side of the paper in Figure 1 is the front of the door 10. As shown in Figures 1 to 4, the door 10 according to this embodiment is installed on a wall W of a structure erected on a floor F.

[0015] 1 to 4, a rectangular wall opening Wa is formed in a wall body W. The frame body of the door 10 according to this embodiment includes a door frame (vertical frames 21, upper frame 22, and lower frame 37) that is provided along the wall opening Wa, and an adjustment mechanism (vertical frame adjustment mechanism 23 and upper frame adjustment mechanism 24) that adjusts the position of the door frame in the thickness direction of the wall body W.

[0016] In the wall opening Wa, vertical frames 21, 21 that form a door frame are provided along the left and right inner surfaces of the wall opening Wa. In addition, in the wall opening Wa, an upper frame 22 that forms a door frame is provided along the upper inner surface of the wall opening Wa. In addition, in the wall opening Wa, a lower frame 37 that forms a door frame is provided along the lower inner surface of the wall opening Wa.

[0017] In the door 10 according to this embodiment, an opening is formed by the vertical frames 21, the upper frame 22, and the lower frame 37. A shielding member 25 extending forward is attached to the front surfaces of the vertical frames 21, the upper frame 22, and the lower frame 37 (see Figures 5, 6, and 8).

[0018] A rail support member 11 is provided on the floor surface F in front of the wall opening Wa along the lower edge of the wall opening Wa. A rail 12 that supports a door main body 30 is fixed to the rail support member 11. In the door 10 according to this embodiment, the door main body 30 slides left and right along the rail 12, thereby opening and closing the opening. In this embodiment, the state in FIG. 1 in which the door main body 30 is positioned in front of the opening is referred to as the "closed state." Furthermore, the state in FIG. 2 in which the door main body 30 has retreated to the right from in front of the opening is referred to as the "open state."

[0019] The door body 30 is formed by combining metal members and is shaped like a plate that is thick in the front-to-rear direction. Specifically, the door body 30 is made by combining door frames made of steel materials of various types and sizes, such as multiple H-shaped steel and L-shaped steel, into a rectangle, and plate materials are provided on both the front and back surfaces of the combined door frame. A protrusion 31 that extends rearward is formed on the peripheral edge of the door body 30.

[0020] A drive case 32 is provided at the lower left of the door body 30. A drive wheel 33 and a motor M, which serves as a drive device, are housed inside the drive case 32. Meanwhile, a driven case 34 is provided at the lower right of the door body 30. A driven wheel 35 is housed inside the driven case 34. When the motor M is driven, the drive wheel 33 rotates, and the drive wheel 33 and the driven wheel 35 roll on the rail 12. This allows the door body 30 to slide left and right along the rail 12.

[0021] As shown in Figure 7, in the door 10 according to this embodiment, the upper frame 22 is fixed to an upper frame support plate 22a. The upper frame support plate 22a is provided with a eaves portion 41 that protrudes forward. A guide rail 42 is provided inside the eaves portion 41 and faces downward.

[0022] Additionally, three guide rollers 36 are provided on the upper portion of the door body 30 via roller support portions 36a. Each guide roller 36 is rotatable about a rotation axis facing in the vertical direction and is housed inside a guide rail 42. The guide rail 42 clamps the guide rollers 36 from the front-to-rear direction, thereby restricting displacement of the door body 30 in the front-to-rear direction and guiding sliding displacement in the left-to-right direction.

[0023] [Adjustment mechanism] Next, an adjustment mechanism for adjusting the position of the door frame in the front-to-rear direction, which is the thickness direction of the wall body W, will be described using Figures 5 to 8. As shown in Figures 1 to 4, the door 10 according to this embodiment is equipped with vertical frame adjustment mechanisms 23, 23 that adjust the position of the vertical frames 21, 21 in the front-to-rear direction, and an upper frame adjustment mechanism 24 that adjusts the position of the upper frame 22 in the front-to-rear direction as adjustment mechanisms. Note that the vertical frame adjustment mechanisms 23, 23 provided on the left and right sides of the door 10 are symmetrical and have the same configuration, so the following description will focus on the vertical frame adjustment mechanism 23 on the left side.

[0024] 3, in the door 10 according to this embodiment, the vertical frame adjustment mechanism 23 includes a support pillar 26, which is an H-beam erected inside the structure as a support member supported by the structure having a wall W, a first support part 27 fixed to the support pillar 26, a second support part 28 fixed to the first support part 27, and an adjustment member 29 fixed to the second support part 28. In addition, a bolt B is provided as a connecting member that connects the adjustment member 29 constituting the support member and the vertical frame 21.

[0025] 5 and 6, the adjustment member 29 constituting the support member is provided adjacent to the rear of the vertical frame 21 in the thickness direction of the wall body W and along the vertical frame 21. In addition, a plurality of vertical spacers 21a with internally threaded holes are fixed at predetermined intervals to the rear surface of the vertical frame 21. Bolts B pass through the adjustment member 29 and are screwed into the internally threaded holes of the respective vertical spacers 21a, thereby connecting the support member and the vertical frame 21.

[0026] 5 and 6, in the vertical frame adjustment mechanism 23, one or more adjustment plates 29b are interposed between an adjustment surface 29a, which is the front surface of the adjustment member 29, and a vertical spacer 21a provided on the vertical frame 21. By adjusting the number of adjustment plates 29b, it is possible to adjust the relative position between the adjustment member 29 and the vertical frame 21. That is, compared to the case where two adjustment plates 29b are used as in the first embodiment shown in Fig. 5, when five adjustment plates 29b are used as in the second embodiment shown in Fig. 6, the vertical frame 21 can be positioned more forward.

[0027] 7, in the door 10 according to this embodiment, the upper frame adjustment mechanism 24 includes a support pillar 26 as a support member supported by a structure including a wall body W, a third support part 43 fixed to the support pillar 26, and adjustment members 44, 44 fixed to both upper and lower ends of the third support part 43. A bolt B is provided as a connecting member that connects the adjustment member 44 constituting the support member to the upper frame 22.

[0028] 8(a) and 8(b), the adjustment members 44·44 constituting the support member are provided adjacent to the rear of the upper frame support plate 22a supporting the upper frame 22 in the thickness direction of the wall body W and along the upper frame support plate 22a. In addition, a plurality of upper spacers 22b with internally threaded holes are fixed at predetermined intervals to the rear surface of the upper frame support plate 22a. Bolts B pass through the adjustment members 44 and are threaded into the internally threaded holes of each upper spacer 22b, thereby connecting the support member to the upper frame support plate 22a and the upper frame 22.

[0029] 8(a) and 8(b), in the upper frame adjustment mechanism 24, one or more adjustment plates 44b are interposed between an adjustment surface 44a, which is the front surface of the adjustment member 44, and an upper spacer 22b provided on the upper frame support plate 22a. By adjusting the number of adjustment plates 44b, it is possible to adjust the relative positions of the adjustment member 44, the upper frame support plate 22a, and the upper frame 22. That is, compared to the first embodiment shown in FIG. 8(a) where there are two adjustment plates 44b, the second embodiment shown in FIG. 8(b) where there are five adjustment plates 44b allows the upper frame support plate 22a and the upper frame 22 to be positioned closer to the front.

[0030] As described above, in the door 10 according to this embodiment, the position of the door frame (the vertical frames 21 and the upper frame 22) in the thickness direction of the wall W can be adjusted by the adjustment mechanisms (the vertical frame adjustment mechanisms 23 and the upper frame adjustment mechanism 24). This makes it possible to adjust the position of the door frame after installation. Therefore, even if the distance between the door frame and the door body 30 after installation is not within a predetermined range, the front-to-rear position of the door frame can be adjusted, making it easier to ensure sealing performance between the door frame and the door body 30.

[0031] In the door 10 according to this embodiment, the door frame is provided with a shielding member 25 that closes the gap between the door body 30 and the door frame when the opening is closed by the door body 30. In the door 10, the front-to-rear position of the door frame can be adjusted, so that the sealing performance of the shielding member 25 between the door frame and the door body 30 can be easily adjusted.

[0032] Furthermore, in the door 10 according to this embodiment, one or more adjustment plates 29b-44b are inserted between the support members (adjustment members 29-44) and the door frame, making it possible to adjust the relative position between the support members and the door frame. This makes it possible to easily adjust the position of the door frame by changing the number of adjustment plates 29b-44b between the support members and the door frame.

[0033] Furthermore, in the door 10 according to this embodiment, multiple vertical spacers 21a and upper spacers 22b are provided at predetermined intervals, so that by partially changing the number of adjustment plates 29b, 44b, it is possible to locally adjust the front-to-rear position of the door frame.

[0034] [First Modification] Next, a first modified example of an adjustment mechanism that adjusts the position of the door frame in the front-to-rear direction, which is the thickness direction of the wall body W, will be described using Figure 9. In the modified examples described below, the overall configuration of the large door other than the adjustment mechanism is generally the same, so a detailed description of the large door will be omitted. As shown in Figure 9, the vertical frame adjustment mechanism 123 of this modified example includes a fixing part 125 that is fixed along the vertical frame 21, and anchor bolts 124 and nuts N that are fixing members that fix the fixing part 125 to the wall body W. Multiple anchor bolts 124 are fixed at predetermined intervals.

[0035] The fixing portion 125 is disposed adjacent to the rear of the wall W in the thickness direction of the wall W. As shown in Fig. 9 , the anchor bolt 124 passes through the fixing portion 125, and the nut N is screwed onto the anchor bolt 124, whereby the fixing portion 125 is fixed to the wall W.

[0036] 9, in the vertical frame adjustment mechanism 123 according to this modification, one or more adjustment plates 125b are interposed between an adjustment surface 125a, which is the front surface of the fixed part 125, and the wall body W. By adjusting the number of these adjustment plates 125b, the relative position between the fixed part 125 and the wall body W can be adjusted. That is, compared to the case where two adjustment plates 125b are used as shown in FIG. 9, if the number of adjustment plates 125b is increased, the vertical frame 21 can be positioned further rearward.

[0037] As described above, the vertical frame adjustment mechanism 123 according to this modified example also makes it possible to adjust the position of the vertical frame 21 in the thickness direction of the wall body W. This makes it possible to adjust the position of the door frame after installation. Therefore, even if the distance between the door frame and the door main body 30 after installation is not within a predetermined range, the front-to-rear position of the door frame can be adjusted, making it easier to ensure sealing performance between the door frame and the door main body 30.

[0038] Furthermore, in the vertical frame adjustment mechanism 123 according to this modification, one or more adjustment plates 125b are inserted between the fixed part 125 and the wall body W, thereby making it possible to adjust the relative position between the vertical frame 21 and the wall body W. This makes it possible to easily adjust the position of the door frame by changing the number of adjustment plates 125b between the fixed part 125 and the wall body W.

[0039] [Second Modification] Next, a second modified example of an adjustment mechanism that adjusts the position of the door frame in the front-to-rear direction, which is the thickness direction of the wall body W, will be described using Figure 10. As shown in Figure 10, the vertical frame adjustment mechanism 223 according to this modified example includes a fixing part 225 fixed along the vertical frame 21, a frame member 224 that is a fixing member for fixing the fixing part 225 to the wall body W, an embedded nut 224a fixed to the frame member 224, and a bolt B. The frame member 224 and the embedded nut 224a are configured integrally with the wall body W. A plurality of embedded nuts 224a are provided at predetermined intervals.

[0040] The fixing portion 225 is disposed adjacent to the rear of the wall W in the thickness direction of the wall W. As shown in Fig. 10, the bolt B penetrates the fixing portion 225 and is threaded into the embedded nut 224a, thereby fixing the fixing portion 225 to the wall W.

[0041] 10, in the vertical frame adjustment mechanism 223 according to this modification, one or more adjustment plates 225b are interposed between an adjustment surface 225a, which is the front surface of the fixed part 225, and the wall body W. By adjusting the number of these adjustment plates 225b, the relative position between the fixed part 225 and the wall body W can be adjusted. That is, compared to the case where two adjustment plates 225b are used as shown in FIG. 10, if the number of adjustment plates 225b is increased, the vertical frame 21 can be positioned further rearward.

[0042] As described above, the vertical frame adjustment mechanism 223 according to this modified example also makes it possible to adjust the position of the vertical frame 21 in the thickness direction of the wall body W. This makes it possible to adjust the position of the door frame after installation. Therefore, even if the distance between the door frame and the door main body 30 after installation is not within a predetermined range, the front-to-rear position of the door frame can be adjusted, making it easier to ensure sealing performance between the door frame and the door main body 30.

[0043] Furthermore, in the vertical frame adjustment mechanism 223 according to this modified example, one or more adjustment plates 225b are inserted between the fixed part 225 and the wall body W, thereby making it possible to adjust the relative position between the vertical frame 21 and the wall body W. This makes it possible to easily adjust the position of the door frame by changing the number of adjustment plates 225b between the fixed part 225 and the wall body W.

[0044] [Other variations] The above embodiment can be modified as appropriate as shown in the following modifications. Each modification may be applied in combination with other modifications as long as no contradiction occurs.

[0045] The door 10 according to this embodiment is configured to open and close by sliding the door body 30 left and right in an opening formed in a wall W, but the large door according to the present invention is not limited to this embodiment. That is, the opening in the wall W can also be configured to be opened and closed by a door body that moves up and down. Also, an opening in a horizontal plane can be configured as a hatch type, where the door body moves horizontally or up and down to open and close.

[0046] The door 10 according to this embodiment is configured so that the door body 30 slides along the rails 12 provided below the opening, but it is also possible to provide wheels on the top of the door body so that the door body slides along rails provided above the opening. It is also possible to displace the door body by displacing a hanging member such as a chain while the door body is suspended by the hanging member.

[0047] In the door 10 according to this embodiment, the door body 30 employs the motor M as a drive device, but as a drive device for the door body 30, other configurations such as a hydraulic mechanism other than an electric mechanism can also be employed.

[0048] In the door 10 according to this embodiment, the shielding member 25 is configured to be provided on the door frame, but it is also possible to configure the shielding member to be provided on the rear surface of the protrusion 31 on the door body 30.

[0049] In the door 10 according to this embodiment, by making the holes in the adjustment members 29 and 44 through which the bolts B pass long holes, it is possible to configure the door frame to allow displacement in directions perpendicular to the longitudinal direction (left-right direction for the vertical frame 21, and up-down direction for the upper frame 22).

[0050] In the door 10 according to this embodiment, the position of the door frame is adjusted by inserting adjustment plates 29b and 44b between the support members (adjustment members 29 and 44) ​​and the door frame, but other methods for adjusting the position of the support members and the door frame, such as a combination of a push bolt and a double nut, can also be used.
