[Overall configuration 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.

As shown in Figures 1 to 4, a rectangular wall opening Wa is formed in the wall W. The frame of the door 10 in this embodiment includes a door frame (vertical frames 21, 21, upper frame 22, and lower frame 37) that is arranged along the wall opening Wa, and adjustment mechanisms (vertical frame adjustment mechanisms 23, 23 and upper frame adjustment mechanism 24) that adjust the position of the door frame in the thickness direction of the wall W.

In the wall opening Wa, vertical frames 21, 21 that form the 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 the 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 the door frame is provided along the lower inner surface of the wall opening Wa.

In the door 10 according to this embodiment, an opening is formed by the vertical frames 21, 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, 21, the upper frame 22, and the lower frame 37 (see Figures 5, 6, and 8).

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

The door body 30 is formed as a plate with a thickness in the front-to-rear direction, constructed by combining metal members. 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, with plate materials provided on both the front and rear of the combined door frame. A protrusion 31 extending rearward is formed on the peripheral edge of the door body 30.

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 driven wheel 35 roll on the rail 12. This allows the door body 30 to slide left and right along the rail 12.

As shown in Figure 7, in the door 10 according to this embodiment, the upper frame 22 is fixed to the 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.

In addition, three guide rollers 36 are mounted on the upper part of the door body 30 via roller support portions 36a. Each guide roller 36 is rotatable around a vertical rotation axis and is housed inside a guide rail 42. The guide rail 42 clamps the guide rollers 36 from the front and rear, thereby restricting the movement of the door body 30 in the front and rear directions and guiding sliding movement in the left and right directions.

[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 with reference to 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 that adjust the positions of the vertical frames 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 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.

In the door 10 according to this embodiment, as shown in FIG. 3, the vertical frame adjustment mechanism 23 includes a support pillar 26, which is an H-beam steel erected inside the structure and serves as a support member supported by the structure including the wall W, a first support portion 27 fixed to the support pillar 26, a second support portion 28 fixed to the first support portion 27, and an adjustment member 29 fixed to the second support portion 28. Additionally, a bolt B is provided as a connecting member connecting the adjustment member 29, which constitutes the support member, to the vertical frame 21.

As shown in Figures 5 and 6, the adjustment member 29 that constitutes the support member is provided adjacent to the rear of the vertical frame 21 in the thickness direction of the wall body W, along the vertical frame 21. Additionally, multiple vertical spacers 21a with female 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 threaded into the female threaded holes of each vertical spacer 21a, connecting the support member and the vertical frame 21.

As shown in Figures 5 and 6, in the vertical frame adjustment mechanism 23, one or more adjustment plates 29b are interposed between the adjustment surface 29a, which is the front surface of the adjustment member 29, and the vertical spacer 21a provided on the vertical frame 21. The relative position between the adjustment member 29 and the vertical frame 21 can be adjusted by adjusting the number of adjustment plates 29b. In other words, compared to the first embodiment shown in Figure 5, where there are two adjustment plates 29b, the second embodiment shown in Figure 6, where there are five adjustment plates 29b, allows the vertical frame 21 to be positioned further forward.

In addition, in the door 10 according to this embodiment, as shown in FIG. 7, the upper frame adjustment mechanism 24 includes a support column 26 as a support member supported by a structure including a wall W, a third support portion 43 fixed to the support column 26, and adjustment members 44, 44 fixed to both the upper and lower ends of the third support portion 43. Furthermore, a bolt B is provided as a connecting member connecting the adjustment member 44 constituting the support member to the upper frame 22.

As shown in Figures 8(a) and (b), the adjustment members 44, 44 that make up the support member are arranged adjacent to and behind the upper frame support plate 22a that supports the upper frame 22 in the thickness direction of the wall body W, along the upper frame support plate 22a. Additionally, multiple upper spacers 22b with female 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 female threaded holes of each upper spacer 22b, connecting the support member to the upper frame support plate 22a and upper frame 22.

As shown in Figures 8(a) and (b), in the upper frame adjustment mechanism 24, one or more adjustment plates 44b are interposed between the adjustment surface 44a, which is the front surface of the adjustment member 44, and the upper spacer 22b provided on the upper frame support plate 22a. By adjusting the number of adjustment plates 44b, the relative position of the adjustment member 44, the upper frame support plate 22a, and the upper frame 22 can be adjusted. In other words, compared to the first embodiment shown in Figure 8(a) where there are two adjustment plates 44b, the second embodiment shown in Figure 8(b) where there are five adjustment plates 44b allows the upper frame support plate 22a and upper frame 22 to be positioned further forward.

As described above, in the door 10 according to this embodiment, the adjustment mechanisms (vertical frame adjustment mechanisms 23 and upper frame adjustment mechanism 24) allow the position of the door frame (vertical frames 21 and upper frame 22) to be adjusted 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 body 30 after installation is not within a specified 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.

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 door body 30 closes the opening. Because the front-to-rear position of the door frame can be adjusted in the door 10, it is possible to easily adjust the sealing performance of the shielding member 25 between the door frame and the door body 30.

In addition, in the door 10 according to this embodiment, one or more adjustment plates 29b/44b are inserted between the support member (adjustment member 29/44) and the door frame, making it possible to adjust the relative position between the support member and the door frame. This makes it easy to adjust the position of the door frame by changing the number of adjustment plates 29b/44b between the support member and the door frame.

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

[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 W, will be described using Figure 9. In the modifications 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 according to this modification includes a fixing portion 125 that is fixed along the vertical frame 21, and anchor bolts 124 and nuts N that are fixing members that fix the fixing portion 125 to the wall W. Multiple anchor bolts 124 are fixed at predetermined intervals.

The fixing portion 125 is positioned adjacent to the rear of the wall W in the thickness direction of the wall W. As shown in Figure 9, the anchor bolt 124 passes through the fixing portion 125 and the nut N is threaded onto the anchor bolt 124, thereby fixing the fixing portion 125 to the wall W.

In the vertical frame adjustment mechanism 123 of this modified example, as shown in Figure 9, one or more adjustment plates 125b are interposed between the adjustment surface 125a, which is the front surface of the fixed part 125, and the wall body W. By adjusting the number of adjustment plates 125b, the relative position between the fixed part 125 and the wall body W can be adjusted. In other words, compared to when two adjustment plates 125b are used as shown in Figure 9, if the number of adjustment plates 125b is increased, the vertical frame 21 can be positioned further rearward.

As described above, the vertical frame adjustment mechanism 123 of 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 body 30 after installation is not within the specified 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.

Furthermore, in the vertical frame adjustment mechanism 123 of this modified example, one or more adjustment plates 125b are inserted between the fixed part 125 and the wall body W, making it possible to adjust the relative position of 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.

[Second Modification]
Next, a second modified example of 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 with reference to Figure 10. As shown in Figure 10, the vertical frame adjustment mechanism 223 according to this modified example includes a fixing portion 225 fixed along the vertical frame 21, a frame member 224 which is a fixing member for fixing the fixing portion 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.

The fixing portion 225 is positioned adjacent to the rear of the wall W in the thickness direction of the wall W. As shown in Figure 10, the fixing portion 225 is fixed to the wall W by threading the bolt B through the fixing portion 225 and into the embedded nut 224a.

In the vertical frame adjustment mechanism 223 of this modified example, as shown in Figure 10, one or more adjustment plates 225b are interposed between the adjustment surface 225a, which is the front surface of the fixed part 225, and the wall W. By adjusting the number of adjustment plates 225b, the relative position between the fixed part 225 and the wall W can be adjusted. In other words, compared to when two adjustment plates 225b are used as shown in Figure 10, if the number of adjustment plates 225b is increased, the vertical frame 21 can be positioned further rearward.

As described above, the vertical frame adjustment mechanism 223 of 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 body 30 after installation is not within the specified 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.

Furthermore, in the vertical frame adjustment mechanism 223 of this modified example, one or more adjustment plates 225b are inserted between the fixed part 225 and the wall body W, making it possible to adjust the relative position of 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.

[Other Modifications]
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.

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 the wall body W, but the large door according to the present invention is not limited to this embodiment. That is, an opening in the wall body W can also be configured to open and close with 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.

The door 10 in this embodiment is configured so that the door body 30 slides along a rail 12 provided below the opening, but it is also possible to provide wheels on the top of the door body and have the door body slide along a rail 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.

In the door 10 according to this embodiment, the door body 30 uses a motor M as its drive device, but it is also possible to use other configurations, such as a hydraulic mechanism, instead of an electric mechanism, as the drive device for the door body 30.

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

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 elongated, it is possible to configure the door frame to allow displacement in directions perpendicular to the longitudinal direction (left-right for the vertical frame 21, and up-down for the upper frame 22).

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 door frame, such as a combination of a push bolt and double nut, can also be used.
