[0007] Technical problem to be solved by the invention

[0008] The inventor of the present disclosure considers installing the door body to the vertical frame in such a door device as follows. That is, in the initial state, the door side of the first hinge and the door side of the second hinge are respectively installed on the door body. Then, the frame side of the first hinge is installed on the door side of the first hinge so that it can be opened and closed, and the frame side of the second hinge is installed on the door side of the second hinge so that it can be opened and closed. Starting from such a state, first, the frame side of the second hinge is temporarily fixed to the second holding part, and then, the frame side of the first hinge is temporarily fixed to the first holding part.

[0009] However, in this case, the inventor of the present disclosure has focused on the following technical problems that may arise. That is, when temporarily fixing the first hinge, since the second hinge is temporarily fixed, a sufficient gap cannot be ensured between the vertical frame and one side of the door body. Therefore, the operator cannot grasp one side of the door body with his hand, but can only put his hand on the side. Therefore, it is difficult to temporarily fix the first hinge.

[0010] The present disclosure is made in view of the above situation, and its purpose is to easily temporarily fix the hinge to the holding portion even in a situation where one side of the door body cannot be grasped by hand and one can only place the hand on the side.

DETAILED DESCRIPTION

[0054] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. However, the present disclosure is not limited to the following embodiments at all, and can be implemented with appropriate modifications within the scope of the present disclosure.

[0055] [First embodiment]

[0056] like Figure 1 As shown, the door device 100 includes a frame 20, a door body 70, a first hinge mounting structure A1, and a second hinge mounting structure A2. Hereinafter, the first hinge mounting structure A1 and the second hinge mounting structure A2 are simply referred to as "hinge mounting structures A1, A2".

[0057] In addition, if Figure 2 As shown, hereinafter, the width direction of the frame 20 is referred to as the "X direction", and the thickness direction of the frame 20 is referred to as the "Y direction". In addition, one side of the X direction is referred to as the "X-side", and the opposite direction thereof is referred to as the "X+ side". In addition, one side of the Y direction is referred to as the "Y-side", and the opposite direction thereof is referred to as the "Y+ side".

[0058] like Figure 1 As shown, the frame 20 includes an upper frame 21, a lower frame 24, and two vertical frames 22, 23. The two vertical frames 22, 23 are arranged in an interval in the X direction. Therefore, the two vertical frames 22, 23 include a vertical frame 22 on the X-side and a vertical frame 23 on the X+ side. Each vertical frame 22, 23 extends in the up-down direction. The upper frame 21 and the lower frame 24 extend in the X direction. The upper frame 21 connects the upper ends of the two vertical frames 22, 23 to each other. The lower frame 24 connects the lower ends of the two vertical frames 22, 23 to each other.

[0059] Hereinafter, the "X-side vertical frame 22" will be referred to as the "vertical frame 22". Figure 3As shown in FIG. 1 , a mounting groove 22a is provided in the vertical frame 22, which is recessed toward the X-side and extends in the vertical direction. A rod member 20b extending in the vertical direction is installed relative to the mounting groove 22a. Therefore, the rod member 20b protrudes from the vertical frame 22 toward the X+ side in a protruding strip shape. However, Figures 10 to 22 In the figure, the rod member 20b is omitted for visibility of the hinge mounting structures A1 and A2.

[0060] The following, such as Figure 1 As shown, the "side portion adjacent to the vertical frame 22 in the door body 70" is referred to as the "door body side portion 72". The door body side portion 72 is mounted on the vertical frame 22 via hinge mounting structures A1 and A2 so as to be openable and closable in the vertical direction. Thus, the door body 70 is opened by rotating to the Y+ side and closed by rotating to the opposite side.

[0061] The following, such as Figure 1 As shown in FIG. 1 , the state in which the door body 70 is closed is referred to as the "door closed state". Figure 2 As shown, the state in which the door body 70 is opened is referred to as an “open door state.” In addition, the width direction of the door body 70 is referred to as a “door width direction,” and the thickness direction of the door body 70 is referred to as a “door thickness direction.”

[0062] exist Figure 1 In the closed state shown, the "door width direction" is the "X direction" and the "door thickness direction" is the "Y direction". In addition, in this closed state, the "door body side 72" is the "X-side side of the door body 70".

[0063] The door body 70 has a plate-like shape extending in the vertical direction and the X direction when the door is closed. A door handle 79 is attached to the end of the upper and lower middle portion of the door body 70 on the X+ side when the door is closed.

[0064] Next, Figure 3 The first hinge installation structure A1 shown in FIG. Figure 6 As shown, the first hinge mounting structure A1 includes a first holding portion 30 and a first hinge 50 .

[0065] A first holding groove 32 recessed toward the X-side is provided at the upper portion of the vertical frame 22. The first holding portion 30 includes a bottom surface and an inner peripheral surface of the first holding groove 32, and an upper member 35a and a lower member 35c attached to the inner side of the first holding groove 32.

[0066] The first retaining groove 32 includes an upper shallow groove 32a, a deep groove 32b, and a lower shallow groove 32c. The deep groove 32b is recessed to the X-side at a predetermined depth. The upper shallow groove 32a is continuous upward from the upper end of the deep groove 32b. The lower shallow groove 32c is continuous downward from the lower end of the deep groove 32b. The depth of the upper shallow groove 32a and the lower shallow groove 32c on the X-side is shallower than the depth of the deep groove 32b on the X-side.

[0067] The upper part 35a and the lower part 35c are both metal parts. The upper part 35a is in a shape that covers the inner side surface of the upper side of the deep groove 32b and the bottom surface of the upper shallow groove 32a. The lower part 35c is in a shape that covers the inner side surface of the lower side of the deep groove 32b and the bottom surface of the lower shallow groove 32c. The upper part 35a is fixed to the bottom surface of the upper shallow groove 32a by two screws Sa. The lower part 35c is fixed to the bottom surface of the lower shallow groove 32c by two screws Sa. Holes 30h for threading the first hinge 50 are provided in the upper part 35a and the lower part 35c. Hereinafter, these holes 30h are referred to as "holes 30h for threading the first retaining portion 30".

[0068] The first hinge 50 is a concealed hinge made of metal or the like. The first hinge 50 includes a first frame side portion 52, a first connecting portion 55, and a first door side portion 57. The first hinge 50 is an integrated hinge. Thus, when the door body 70 is mounted relative to the vertical frame 2, any of the first frame side portion 52, the first connecting portion 55, and the first door side portion 57 cannot be separated from the other portions. A first groove 75 is provided at the upper portion of one side portion 72 of the door body. The first door side portion 57 is accommodated in the first groove 75.

[0069] The first door side portion 57 is adjusted in the vertical direction relative to the door body side portion 72 by two upper and lower screws Sd, and is fixed by Figure 5 The upper portion of the first door side portion 57 is mounted to a side portion 72 of the door body by two screws Sc. The lower portion of the first door side portion 57 is mounted to a side portion 72 of the door body by another two screws Sc.

[0070] like Figure 6 As shown, the first frame side portion 52 includes an inner portion 521 and an outer portion 525. The inner portion 521 is installed on the first door side portion 57 so as to be openable and closable in the up-down direction via the first connecting portion 55. The outer portion 525 includes an upper flange 525a, a base 525b, and a lower flange 525c. The base 525b is in the shape of a plate extending in the up-down direction. The upper end Ue and the lower end De of the base 525b protrude to the X+ side. Between the upper end Ue and the lower end De in the base 525b, the inner portion 521 is installed so as to be positionally adjustable in the Y direction by two upper and lower screws Sf.

[0071] The upper flange 525a extends upward from the end of the X+ side of the upper end Ue of the base 525b. The lower flange 525c extends downward from the end of the X+ side of the lower end De of the base 525b. Holes 52h for screwing the first frame side portion 52 to the first retaining portion 30 are provided in the upper flange 525a and the lower flange 525c. Hereinafter, these holes 52h are referred to as "holes 52h for screwing the first frame side portion 52".

[0072] The upper flange 525a is received in the upper shallow groove 32a, the base 525b is received in the deep groove 32b, and the lower flange 525c is received in the lower shallow groove 32c.

[0073] like Figure 2 As shown, the cover Cv is mounted on the first hinge 50. Specifically, the cover Cv is mounted on the first frame side portion 52 so as to block the opening of the first holding groove 32. In addition, the cover Cv is mounted on the first door side portion 57 so as to block the opening of the first groove 75.

[0074] Next, Figure 8 The second hinge installation structure shown in FIG. Fig. 9 As shown, the second hinge mounting structure A2 includes a second holding portion 40 and a second hinge 60. It should be noted that in this embodiment, the second hinge 60 and the first hinge 50 have the same shape. However, they may have different shapes.

[0075] A second retaining groove 42 is provided at the lower portion of the vertical frame 22. The second retaining portion 40 includes the bottom surface and inner peripheral surface of the second retaining groove 42, and an upper component 45a and a lower component 45c installed inside the second retaining groove 42. The second retaining groove 42 includes an upper shallow groove 42a, a deep groove 42b, and a lower shallow groove 42c. Holes 40h for threaded fixing are provided in the upper component 45a and the lower component 45c. Hereinafter, these holes 40h for threaded fixing are referred to as "holes 40h for threaded fixing of the second retaining portion 40".

[0076] The second hinge 60 includes a second frame side portion 62, a second connecting portion 65, and a second door side portion 67. A second groove 76 is provided at the lower portion of a side portion 72 of the door body. The second frame side portion 62 includes an inner portion 621 and an outer portion 625. The outer portion 625 includes an upper flange 625a, a base portion 625b, and a lower flange 625c. Holes 62h for screw fixing are provided at the upper flange 625a and the lower flange 625c, respectively. Hereinafter, the holes 62h for screw fixing are referred to as "holes 62h for screw fixing of the second frame side portion 62".

[0077] A more detailed description of the second hinge installation structure A2 shown above is the same as the description of the first hinge installation structure A1 described above, with the following substitutions. That is, "first" is replaced with "second", "upper part of the vertical frame 22" is replaced with "lower part of the vertical frame 22", "upper part of one side of the door body 72" is replaced with "lower part of one side of the door body 72", and each figure number and each reference numeral are replaced with the corresponding figure number and reference numeral.

[0078] It should be noted that the "first frame side 52" can be replaced by the "frame side of the first hinge". In addition, the "first door side 57" can be replaced by the "door side of the first hinge". In addition, the "second frame side 62" can be replaced by the "frame side of the second hinge". In addition, the "second door side 67" can be replaced by the "door side of the second hinge". In addition, the "first retaining portion 30" in the first retaining portion 30 and the second retaining portion 40 can be simply replaced by the "retaining portion". In addition, the "first hinge 50" in the first hinge 50 and the second hinge 60 can be simply replaced by the "hinge".

[0079] Hereinafter, the first hinge 50 and the second hinge 60 are referred to as "hinges 50, 60". Figure 2 The side where the hinges 50 and 60 are biased by the deadweight of the door body 70 in the open state in the Y direction is referred to as the “Y direction deadweight side.” The “Y direction deadweight side” may be replaced by the “thickness direction deadweight side.”

[0080] Specifically, Figure 3 The first hinge 50 shown is installed at a position above the center of gravity of the door body 70. Therefore, the Y-direction deadweight side of the first hinge 50 is the Y+ side. Figure 8 The second hinge 60 shown is installed at a position lower than the center of gravity of the door body 70. Therefore, the self-weight side in the Y direction with respect to the second hinge 60 is the Y-side.

[0081] Next, the technical problems to be solved in this embodiment are described. Figure 1 When assembling the door device 100 shown in FIG. 1 , the door body 70 is mounted on the vertical frame 22 as follows. That is, in the initial state, as shown in FIG. Figure 6 As shown, the first door side portion 57 is mounted on the upper portion of a side portion 72 of the door body, as shown in FIG. Fig. 9 As shown, the second door side portion 67 is installed at the lower part of one side portion 72 of the door body. Fig. 9 The second frame side portion 62 shown in FIG. 1 is temporarily fixed to the second holding portion 40. Next, Figure 6 The first frame side portion 52 shown is temporarily fixed to the first holding portion 30 .

[0082] In this case, when temporarily fixing the first frame side portion 52, since the second frame side portion 62 is temporarily fixed, a sufficient gap cannot be ensured between the vertical frame 22 and the door body side portion 72. Therefore, the operator cannot grasp the door body side portion 72 with his hand, and can only put his hand on the door body side portion 72. Therefore, it is difficult to temporarily fix the first frame side portion 52. In addition, when temporarily fixing the first frame side portion 52, the temporary fixation of the second door side portion 67 may fall off.

[0083] In order to solve the above technical problems, the door device 100 of this embodiment further has the following structure. Figure 4 As shown, the first holding portion 30 is provided with a first temporarily fixed portion 30 t , and the first frame side portion 52 is provided with a first temporarily fixed portion 52 t .

[0084] like Figure 6 As shown in FIG. 1 , the first temporary fixing portion 30t is a protrusion protruding downward from the ends of the X+ side and the Y+ side of the lower end of the upper member 35a. Figure 7 As shown, the first temporarily fixed portion 52t is the inner side of the slit provided at the ends of the X+ side and the Y+ side of the upper end Ue of the base 525b of the outer portion 525. The slit is a slit with the X direction as the width direction and the Y direction as the length direction, and is open in the up-down direction and the Y+ side.

[0085] In addition, if Fig. 9 As shown, the second holding portion 40 is provided with a second temporary fixing portion 40t, and the second temporarily fixed portion 62t is provided on the second frame side portion 62. The second temporarily fixed portion 40t is a protrusion protruding upward from the middle portion in the Y direction of the end portion on the X+ side of the upper end portion of the lower part 45c. On the other hand, the second temporarily fixed portion 62t is the inner peripheral surface of the through hole provided at the lower end portion De of the base portion 625b of the outer portion 625 and penetrating in the vertical direction.

[0086] It should be noted that the "first temporarily fixing portion 30t" in the first temporarily fixing portion 30t and the second temporarily fixing portion 40t can be simply replaced by the "temporarily fixing portion". In addition, the "first temporarily fixed portion 52t" in the first temporarily fixed portion 52t and the second temporarily fixed portion 62t can be simply replaced by the "temporarily fixed portion".

[0087] Next, Figure 1 The method of installing the door body 70 relative to the vertical frame 22 is described. It should be noted that the installation method here can be replaced by a "hinge installation method".

[0088] First, in the initial state, Figure 6 As shown, the first door side portion 57 is mounted on the upper portion of one side portion 72 of the door body. Fig. 9As shown, the second door side portion 67 is installed at the lower portion of a side portion 72 of the door body.

[0089] Starting from this state, Fig.10 As shown, the operator moves the lower portion of one side 72 of the door body toward the X-side, as shown in FIG. Fig.11 As shown, the second frame side portion 62 is inserted into the second retaining groove 42. Fig.12 As shown in FIG. 1 , the second temporarily fixed portion 62 t is arranged above the second temporarily fixed portion 40 t.

[0090] Next, if Fig.13 As shown, the operator lowers one side of the door body 72 to engage the second temporarily fixed portion 62t with the second temporarily fixed portion 40t. Therefore, the second frame side portion 62 is temporarily fixed to the second holding portion 40. At this time, the threaded fixing hole 62h of the second frame side portion 62 and the threaded fixing hole 40h of the second holding portion 40 are connected to each other.

[0091] Next, the operator Fig.14 As shown in FIG. 1 , the upper portion of one side 72 of the door body is moved toward the X-side, as shown in FIG. Fig.15 As shown in FIG. 5 , the first frame side portion 52 is inserted into the first retaining groove 32. Fig.16 As shown in FIG. 1 , the first temporarily fixed portion 52 t is arranged on the Y-side relative to the first temporarily fixed portion 30 t.

[0092] Next, if Fig.17 As shown, the operator moves the upper part of one side portion 72 of the door body toward the Y+ side, thereby sliding the first frame side portion 52 toward the Y+ side relative to the first holding portion 30. Therefore, the first temporarily fixed portion 30t is arranged inside the first temporarily fixed portion 52t, and the first temporarily fixed portion 52t is engaged with the first temporarily fixed portion 30t. As a result, the first frame side portion 52 is temporarily fixed to the first holding portion 30. At this time, the threaded fixing hole 52h of the first frame side portion 52 and the threaded fixing hole 30h of the first holding portion 30 are connected to each other.

[0093] Next, the operator Fig.18 As shown, Fig.17 The holes 52h, 30h and 40h for threaded fixing in the first hinge mounting structure A1 shown in FIG. Fig.13 The screw holes 62h, 40h in the second hinge mounting structure A2 shown are used to mount screws Sb. That is, the first frame side 52 is formally fixed to the first holding portion 30 by two upper and lower screws Sb, and the second frame side 62 is formally fixed to the second holding portion 40 by two upper and lower screws Sb.

[0094] Through the above operations, one side portion 72 of the door body is mounted to the vertical frame 22 via the first hinge mounting structure A1 and the second hinge mounting structure A2.

[0095] Next, a method of removing the door body 70 from the vertical frame 22 will be described. It should be noted that this method can also be replaced by a "hinge removal method".

[0096] First, the operators Fig.18 In the state shown, that is, in the state where the first frame side portion 52 is temporarily and formally fixed to the first holding portion 30 and the second frame side portion 62 is temporarily and formally fixed to the second holding portion 40, the following operation is performed. That is, the upper and lower two screws Sb that formally fix the first frame side portion 52 are removed, and the upper and lower two screws Sb that formally fix the second frame side portion 62 are removed.

[0097] Next, the operator passes the following Fig.19 As shown, the upper portion of one side of the door 72 is moved toward the Y-side, so that the first frame side portion 52 slides toward the Y-side relative to the first holding portion 30. Thus, the first temporarily fixed portion 52t is released from the first temporarily fixed portion 30t, and the temporary fixation of the first frame side portion 52 is released.

[0098] Next, the operator passes the following Fig. 20 As shown, the upper portion of one side portion 72 of the door body is moved toward the X+ side, thereby removing the first frame side portion 52 from the first holding groove 32 .

[0099] Next, the operator Fig.21 As shown, the lower portion of one side portion 72 of the door body is slightly lifted. As a result, the engagement between the second temporarily fixed portion 62t and the second temporarily fixed portion 40t is released, and the temporary fixation of the second frame side portion 62 is released.

[0100] Next, the operator Fig. 22 As shown, the lower portion of one side portion 72 of the door body is moved toward the X+ side, thereby removing the second frame side portion 62 from the second holding groove 42 .

[0101] Through the above operations, one side portion 72 of the door body is removed from the vertical frame 22.

[0102] The configuration and effects of this embodiment are summarized below.

[0103] like Fig.17As shown, if the first frame side portion 52 is slid toward the Y+ side, that is, toward the self-weight side in the Y direction, relative to the first holding portion 30, the first temporarily fixed portion 52t is engaged with the first temporarily fixed portion 30t. Therefore, the operator can engage the first temporarily fixed portion 52t with the first temporarily fixed portion 30t and temporarily fix the first frame side portion 52 to the first holding portion 30 by simply sliding the first frame side portion 52 toward the Y+ side relative to the first holding portion 30 due to the self-weight of the door body 70. Therefore, even if the operator cannot grasp the side portion 72 of the door body with his hand and can only place his hand against the side portion 72 of the door body, he can easily temporarily fix the first frame side portion 52 to the first holding portion 30.

[0104] Furthermore, at this time, even if the operator releases his hand from the door body 70, the temporary fixation of the first frame side portion 52 can be stably maintained by the weight of the door body 70. Therefore, the operator can formally fix the first frame side portion 52 to the first holding portion 30 while stably maintaining the temporary fixation. Therefore, the operator can also easily perform the formal fixing operation.

[0105] The first temporarily fixed portion 30t is a protrusion protruding downward in the upper portion of the first holding portion 30. The first temporarily fixed portion 52t is the inner side surface of the gap into which the first temporarily fixed portion 30t enters when the first frame side portion 52 slides toward the Y+ side relative to the first holding portion 30. Therefore, the first temporarily fixed portion 52t and the first temporarily fixed portion 30t can be realized by such a simple structure.

[0106] like Fig.14 As shown, the first retaining portion 30 is provided with a first retaining groove 32 into which the first frame side portion 52 can be inserted. Fig.15 As shown, the first frame side portion 52 is embedded relative to the first retaining groove 32. Fig.16 The state shown starts as Fig.17 As shown, the first frame side portion 52 is slid toward the Y+ side relative to the first holding portion 30, and the first temporarily fixed portion 52t is engaged with the first temporarily fixed portion 30t. Therefore, the operator inserts the first frame side portion 52 into the first holding groove 32, roughly positions the first frame side portion 52 relative to the first holding portion 30, and can engage the first temporarily fixed portion 52t with the first temporarily fixed portion 30t. Therefore, at this point, the operator can also easily temporarily fix the first frame side portion 52 to the first holding portion 30.

[0107] like Fig.17As shown in FIG. 1 , the first frame side portion 52 and the first holding portion 30 are provided with screw fixing holes 52h and 30h that are interconnected when the first temporarily fixed portion 52t is engaged with the first temporarily fixed portion 30t. Therefore, if the first temporarily fixed portion 52t is engaged with the first temporarily fixed portion 30t, these screw fixing holes 52h and 30h are necessarily interconnected. In this state, the operator inserts the screws Sb into the screw fixing holes 52h and 30h, as shown in FIG. Fig.18 As shown, the first frame side portion 52 is permanently fixed to the first holding portion 30. Therefore, at this point, the operator can also easily permanently fix the first frame side portion 52.

[0108] like Fig.13 As shown, after temporarily fixing the second frame side portion 62, as shown in Fig.17 The first frame side portion 52 is temporarily fixed as shown. Therefore, the first frame side portion 52 can be engaged with the first holding portion 30 by simply sliding the first frame side portion 52 located at the upper portion of the door side portion 72 toward the Y+ side relative to the first holding portion 30 with the second frame side portion 62 that has been temporarily fixed as a fulcrum, that is, with the lower portion of the door side portion 72 as a fulcrum. Therefore, at this point, the operator can also easily temporarily fix the first frame side portion 52.

[0109] like Fig. 9 As shown, a second temporary fixing portion 40t protruding upward is provided at the lower portion of the second holding portion 40. A second temporarily fixed portion 62t engaged with the second temporary fixing portion 40t is provided at the lower portion of the second frame side portion 62. In other words, the lower end portion of the second holding portion 40 and the lower end portion of the second frame side portion 62 have an interlocking shape that interlocks with each other in the vertical direction. Fig.13 As shown, by the fitting of the fitting shape, the second frame side portion 62 is temporarily fixed to the second holding portion 40. Therefore, although the second frame side portion 62 is difficult to temporarily fix compared to the first frame side portion 52, it is difficult to fall off temporarily. By first temporarily fixing the second frame side portion 62 that is difficult to fall off, and then temporarily fixing the first frame side portion 52 that is easy to temporarily fix, the two temporary fixing operations can be efficiently performed.

[0110] When disassembling the first hinge 50, remove Fig.18 The screws Sb shown in the figure release the formal fixation of the first frame side 52 and the second frame side 62. In this state, Fig.19 As shown, the first frame side portion 52 is slid relative to the first holding portion 30 toward the Y-side, that is, toward the side opposite to the self-weight side in the Y direction. As a result, the engagement between the first temporarily fixed portion 52t and the first temporarily fixed portion 30t is released, and the temporary fixation of the first frame side portion 52 is released. Therefore, the temporary fixation of the first frame side portion 52 can be released by such a simple action.

[0111] Fig.19 The temporary fixing release operation of the first frame side portion 52 shown in FIG. Fig.21 The temporary fixing release operation of the second frame side portion 62 shown in FIG. Fig.19 When the temporary fixation of the first frame side portion 52 is released, the second frame side portion 62 is still temporarily fixed. The first temporarily fixed portion 52t and the first temporarily fixed portion 30t can be released by sliding the first frame side portion 52 located at the upper part of the door side portion 72 toward the Y-side with the second frame side portion 62 still temporarily fixed as a fulcrum, that is, with the lower part of the door side portion 72 as a fulcrum. Then, after the first temporarily fixed portion 52t and the first temporarily fixed portion 30t are released and the temporary fixation of the first frame side portion 52 is released, Fig.21 Except for the temporary fixation of the second frame side portion 62 shown, there is no restriction on the door body 70. Therefore, the operator can relatively freely move the door body 70. Thus, the operator can also relatively easily release the temporary fixation of the second frame side portion 62.

[0112] [Other embodiments]

[0113] The above embodiment can be implemented by being modified as follows, for example.

[0114] and Figure 1 On the contrary, the first hinge mounting structure A1 may be on the lower side and the second hinge mounting structure A2 may be on the upper side. Figure 1 The second hinge installation structure A2 is set at the position of the first hinge installation structure A1 shown in FIG. Figure 1 The first hinge mounting structure A1 is set at the position of the second hinge mounting structure A2 shown in the figure. However, in this case, in the first hinge mounting structure A1 located at the lower part of the door device 100, the self-weight side in the Y direction is not the Y+ side but the Y- side. Figure 4 On the contrary, the first frame side portion 52 is slid toward the Y-side relative to the first holding portion 30, and the first temporarily fixed portion 52t is temporarily fixed to the first temporarily fixed portion 30t. Figure 4 On the contrary, the first temporarily fixed portion 30 t is provided at the end portion on the Y-side of the first holding portion 30 . Furthermore, the first temporarily fixed portion 52 t is provided at the end portion on the Y-side of the first frame side portion 52 .

[0115] Also available in Figure 1 The first hinge mounting structure A1 is provided on both the upper and lower parts of the door device 100 shown in FIG. Figure 1The second hinge installation structure A2 located at the lower part of the door device 100 is replaced by the first hinge installation structure A1. However, in this case, the first hinge installation structure A1 at the lower side is different from the first hinge installation structure A2 at the lower part of the door device 100. Figure 4 On the contrary, the first frame side portion 52 is slid toward the Y-side relative to the first holding portion 30 , and the first temporarily fixed portion 52 t is temporarily fixed to the first temporarily fixed portion 30 t .

[0116] and Figure 6 On the contrary, the first temporarily fixed portion 30t may be a protrusion protruding upward from the lower part 35c, and the first temporarily fixed portion 52t may be provided at the lower part of the first frame side portion 52. Furthermore, the first temporarily fixed portion 52t may be a convex portion protruding toward the self-weight side in the Y direction, and the first temporarily fixed portion 30t may be a concave portion engaged with the convex portion. In addition, the first temporarily fixed portion 52t may be a concave portion recessed from the end of the self-weight side in the Y direction of the first frame side portion 52 toward the opposite side of the self-weight side in the Y direction, and the first temporarily fixed portion 30t may be a convex portion engaged with the concave portion. In these cases, if the first frame side portion 52 is slid toward the self-weight side in the Y direction relative to the first holding portion 30, the first temporarily fixed portion 52t and the first temporarily fixed portion 30t are engaged with each other, and if it is slid toward the opposite side of the self-weight side in the Y direction, the engagement is released.

[0117] The hinges 50 and 60 may be other than hidden hinges such as flag hinges. In addition to the first hinge 50 and the second hinge 60, Figure 1 The illustrated door body side 72 is further provided with other hinges, and in addition to the first retaining portion 30 and the second retaining portion 40, other retaining portions may be further provided on the vertical frame 22. In other words, the door device 100 may have more than three hinges.

[0118] Figure 6 The first hinge 50 shown may be a non-integrated hinge. That is, when the door body 70 is installed relative to the vertical frame 22, the first hinge 50 may be configured so that any part of the first frame side portion 52, the first connecting portion 55, and the first door side portion 57 can be separated from the other parts. Fig. 9 The second hinge 60 shown may also be a non-integrated hinge. However, as described above, in the above embodiment, even if Figure 1 The first hinge 50 and the second hinge 60 shown are integral hinges, and since one side 72 of the door body can be mounted to the vertical frame 22 without any problem, it is preferred that the first hinge 50 and the second hinge 60 are integral hinges.
