[0029] The upper flange 525a extends upward from the X + - side end portion of the upper end portion Ue of the base portion 525b. The lower flange 525c extends downward from the X + - side end portion of the lower end portion De of the base portion 525b. The upper flange 525a and the lower flange 525c are provided with holes 52h for screwing the first frame side portion 52 to the first holding portion 30. Hereinafter, these holes 52h are referred to as "holes 52h for screwing the first frame side portion 52".

[0030] The upper flange 525a is received in the upper shallow groove 32a. The base portion 525b is received in the deep groove 32b. The lower flange 525c is received in the lower shallow groove 32c.

[0031] As shown in FIG. 2, a cover Cv is attached to the first latch 50. Specifically, with respect to the first frame side portion 52, the cover Cv is attached in a manner that closes the opening of the first holding groove 32. Also, with respect to the first door side portion 57, the cover Cv is attached in a manner that closes the opening of the first groove 75.

[0032] Next, the second hinge attachment structure shown in FIG. 8 will be described. As shown in FIG. 9, the second hinge attachment structure A2 includes a second holding portion 40 and a second hinge 60. In this embodiment, the second hinge 60 has the same shape as the first hinge 50. However, it may have a different shape.

[0033] A second holding groove 42 is provided at the lower part of the vertical frame 22. The second holding portion 40 includes the bottom surface and the inner peripheral surface of the second holding groove 42, and an upper member 45a and a lower member 45c attached inside the second holding groove 42. The second holding groove 42 includes an upper shallow groove 42a, a deep groove 42b, and a lower shallow groove 42c. The upper member 45a and the lower member 45c are provided with screw holes 40h for screwing. Hereinafter, these screw holes 40h for screwing will be referred to as "the screw holes 40h for screwing of the second holding portion 40".

[0034] 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 part of one 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. Screw holes 62h for screwing are provided in the upper flange 625a and the lower flange 625c, respectively. Hereinafter, these screw holes 62h for screwing will be referred to as "the screw holes 62h for screwing of the second frame side portion 62".

[0035] The more detailed description of the second hinge attachment structure A2 shown above is the same as the description of the first hinge attachment structure A1 described above, with the following replacements. That is, replace "first" with "second", "the upper part of the vertical frame 22" with "the lower part of the vertical frame 22", "the upper part of one side portion 72 of the door body" with "the lower part of one side portion 72 of the door body", and replace each figure number and each reference sign with the corresponding ones.

[0036] Note that the "first frame side part 52" may be read as the "first numbered frame side part". Also, the "first door side part 57" may be read as the "first numbered door side part". Further, the "second frame side part 62" may be read as the "second numbered frame side part". Also, the "second door side part 67" may be read as the "second numbered door side part". Also, the "first holding part 30" of the first holding part 30 and the second holding part 40 may be simply read as the "holding part". Also, the "first number 50" of the first number 50 and the second number 60 may be simply read as the "number".

[0037] Hereinafter, the first number 50 and the second number 60 are simply referred to as "numbers 50, 60". Also, in the Y direction shown in FIG. 2, the direction on the side where the numbers 50, 60 are biased by the self-weight of the door body 70 in the door open state is referred to as the "Y direction self-weight side". The "Y direction self-weight side" may be read as the "expected direction self-weight side".

[0038] Specifically, the first number 50 shown in FIG. 3 is attached above the center of gravity of the door body 70. Therefore, the Y direction self-weight side for the first number 50 is the Y+ side. On the other hand, the second number 60 shown in FIG. 8 is attached below the center of gravity of the door body 70. Therefore, the Y direction self-weight side for the second number 60 is the Y- side.

[0039] Next, the problems to be solved in this embodiment will be described. When assembling the door device 100 shown in FIG. 1, the door body 70 is attached to the vertical frame 22 as follows. That is, in the initial state, as shown in FIG. 6, the first door side part 57 is attached to the upper part of the side part 72 of the door body, and as shown in FIG. 9, the second door side part 67 is attached to the lower part of the side part 72 of the door body. From this state, first, the second frame side part 62 shown in FIG. 9 is temporarily fixed to the second holding part 40, and then the first frame side part 52 shown in FIG. 6 is temporarily fixed to the first holding part 30.

[0040] In this case, during the temporary fixing operation of the first frame side portion 52, since the second frame side portion 62 is temporarily fixed, a sufficient gap cannot be secured between the vertical frame 22 and the side portion 72 of the door body. Therefore, the operator cannot grasp the side portion 72 of the door body by hand and can only place a hand on the side portion 72 of the door body. As a result, the temporary fixing operation of the first frame side portion 52 becomes difficult. Further, during the temporary fixing operation of the first frame side portion 52, there is a risk that the temporary fixing of the second door side portion 67 may become loose.

[0041] In order to solve the above problems, the door device 100 of the present embodiment further has the following configuration. That is, as shown in FIG. 4, the first holding portion 30 is provided with a first temporary fixing portion 30t, and the first frame side portion 52 is provided with a first portion to be temporarily fixed 52t.

[0042] As shown in FIG. 6, the first temporary fixing portion 30t is a protrusion protruding downward from the end portions on the X+ side and the Y+ side at the lower end portion of the upper side member 35a. As shown in FIG. 7, the first portion to be temporarily fixed 52t is the inner side surface of a slit provided at the end portions on the X+ side and the Y+ side at the upper end Ue of the base portion 525b of the outer portion 525. The slit has the X direction as the width direction and the Y direction as the length direction, and is open in the vertical direction and toward the Y+ side.

[0043] Further, as shown in FIG. 9, the second holding portion 40 is provided with a second temporary fixing portion 40t, and the second frame side portion 62 is provided with a second portion to be temporarily fixed 62t. The second temporary fixing portion 40t is a protrusion protruding upward from the intermediate portion in the Y direction of the end portion on the X+ side at the upper end portion of the lower side member 45c. On the other hand, the second portion to be temporarily fixed 62t is the inner peripheral surface of a through hole penetrating in the vertical direction provided at the lower end portion De of the base portion 625b of the outer portion 625.

[0044] Note that the "first temporary fixing portion 30t" among the first temporary fixing portion 30t and the second temporary fixing portion 40t may be simply read as "temporary fixing portion". Also, the "first portion to be temporarily fixed 52t" among the first portion to be temporarily fixed 52t and the second portion to be temporarily fixed 62t may be simply read as "portion to be temporarily fixed".

[0045] Next, a method for attaching the door body 70 to the vertical frame 22 shown in FIG. 1 will be described. Note that the attachment method described here can also be read as "hinge attachment method".

[0046] First, in the initial state, as shown in FIG. 6, the first door side portion 57 is attached to the upper part of the door body side portion 72. Also, as shown in FIG. 9, the second door side portion 67 is attached to the lower part of the door body side portion 72.

[0047] From this state, as shown in FIG. 10, the operator moves the lower part of the door body side portion 72 to the X - side, and as shown in FIG. 11, fits the second frame side portion 62 into the second holding groove 42. As a result, as shown in FIG. 12, the second temporarily fixed portion 62t is arranged above the second temporary fixing portion 40t.

[0048] Next, as shown in FIG. 13, the operator lowers the door body side portion 72 to fit the second temporarily fixed portion 62t into the second temporary fixing portion 40t. As a result, the second frame side portion 62 is temporarily fixed to the second holding portion 40. At this time, the screw hole 62h of the second frame side portion 62 and the screw hole 40h of the second holding portion 40 communicate with each other.

[0049] Next, as shown in FIG. 14, the operator moves the upper part of the door body side portion 72 to the X - side, and as shown in FIG. 15, fits the first frame side portion 52 into the first holding groove 32. As a result, as shown in FIG. 16, the first temporarily fixed portion 52t is arranged on the Y - side of the first temporary fixing portion 30t.

[0050] Next, as shown in FIG. 17, the operator moves the upper part of the door body side portion 72 to the Y + side to slide the first frame side portion 52 to the Y + side with respect to the first holding portion 30. Thereby, the first temporary fixing portion 30t is arranged inside the first temporarily fixed portion 52t, and the first temporarily fixed portion 52t engages with the first temporary fixing portion 30t. As a result, the first frame side portion 52 is temporarily fixed to the first holding portion 30. At this time, the screw hole 52h of the first frame side portion 52 and the screw hole 30h of the first holding portion 30 communicate with each other.

[0051] Next, the operator attaches screws Sb to the screwing holes 52h and 30h in the first hinge attachment structure A1 shown in FIG. 17 and the screwing holes 62h and 40h in the second hinge attachment structure A2 shown in FIG. 13, respectively, as shown in FIG. 18. That is, the first frame side portion 52 is firmly fixed to the first holding portion 30 with two screws Sb vertically, and the second frame side portion 62 is firmly fixed to the second holding portion 40 with two screws Sb vertically.

[0052] Through the above operations, one side portion 72 of the door body is attached to the vertical frame 22 via the first hinge attachment structure A1 and the second hinge attachment structure A2.

[0053] Next, a method for removing the door body 70 from the vertical frame 22 will be described. Note that this method may be read as "hinge removal method".

[0054] First, the operator performs the following operations from the state shown in FIG. 18, that is, the state where the first frame side portion 52 is temporarily fixed and firmly fixed to the first holding portion 30 and the second frame side portion 62 is temporarily fixed and firmly fixed to the second holding portion 40. That is, the two screws Sb that firmly fix the first frame side portion 52 are removed, and the two screws Sb that firmly fix the second frame side portion 62 are removed.

[0055] Next, as shown in FIG. 19, the operator moves the upper part of the one side portion 72 of the door body to the Y - side, thereby sliding the first frame side portion 52 to the Y - side with respect to the first holding portion 30. As a result, the engagement between the first temporarily fixed portion 52t and the first temporary fixing portion 30t is released, and the temporary fixing of the first frame side portion 52 is released.

[0056] Next, as shown in FIG. 20, the operator moves the upper part of the one side portion 72 of the door body to the X + side, thereby removing the first frame side portion 52 from the first holding groove 32.

[0057] Next, as shown in FIG. 21, the operator slightly lifts the lower part of the one side portion 72 of the door body. As a result, the fitting between the second temporarily fixed portion 62t and the second temporary fixing portion 40t is released, and the temporary fixing of the second frame side portion 62 is released.

[0058] Next, as shown in FIG. 22, the operator moves the lower part of the side portion 72 of the door body to the X+ side to remove the second frame side portion 62 from the second holding groove 42.

[0059] By the above operations, the side portion 72 of the door body is removed from the vertical frame 22.

[0060] The configuration and effects of the present embodiment are summarized below.

[0061] As shown in FIG. 17, when the first frame side portion 52 is slid with respect to the first holding portion 30 to the Y+ side, that is, to the self-weight side in the Y direction, the first temporarily fixed portion 52t engages with the first temporary fixing portion 30t. Therefore, the operator can engage the first temporarily fixed portion 52t with the first temporary fixing portion 30t and temporarily fix the first frame side portion 52 to the first holding portion 30 only by sliding the first frame side portion 52 with respect to the first holding portion 30 to the Y+ side according to the self-weight of the door body 70. Therefore, even in a situation where the operator cannot grasp the side portion 72 of the door body by hand and can only place a hand on the side portion 72 of the door body, the operator can easily temporarily fix the first frame side portion 52 to the first holding portion 30.

[0062] Moreover, at this time, even if the operator releases the hand from the door body 70, the temporary fixing of the first frame side portion 52 is stably maintained by the self-weight of the door body 70. Therefore, the operator can permanently fix the first frame side portion 52 to the first holding portion 30 in a state where the temporary fixing is stably maintained. Therefore, the operator can easily perform the permanent fixing work.

[0063] The first temporary fixing portion 30t is a protrusion protruding downward at the upper part of the first holding portion 30. The second temporarily fixed portion 62t is the inner surface of a slit into which the first temporary fixing portion 30t enters inward when the first frame side portion 52 is slid to the Y+ side with respect to the first holding portion 30. Therefore, the first temporarily fixed portion 52t and the first temporary fixing portion 30t can be realized with such a simple configuration.

[0064] As shown in FIG. 14, the first holding portion 30 is provided with a first holding groove 32 into which the first frame side portion 52 can be inserted. As shown in FIG. 15, the first frame side portion 52 is fitted into the first holding groove 32. From the state shown in FIG. 16, as shown in FIG. 17, when the first frame side portion 52 is slid in the Y+ direction with respect to the first holding portion 30, the first temporarily fixed portion 52t engages with the first temporary fixing portion 30t. Therefore, the operator can insert the first frame side portion 52 into the first holding groove 32, roughly position the first frame side portion 52 with respect to the first holding portion 30, and then engage the first temporarily fixed portion 52t with the first temporary fixing portion 30t. Therefore, also in this regard, the operator can easily temporarily fix the first frame side portion 52 to the first holding portion 30.

[0065] As shown in FIG. 17, the first frame side portion 52 and the first holding portion 30 are provided with screw holes 52h and 30h that communicate with each other in a state where the first temporarily fixed portion 52t engages with the first temporary fixing portion 30t. Therefore, when the first temporarily fixed portion 52t is engaged with the first temporary fixing portion 30t, those screw holes 52h and 30h necessarily communicate with each other. In that state, the operator secures the first frame side portion 52 to the first holding portion 30 with screws Sb inserted into those screw holes 52h and 30h, as shown in FIG. 18. Therefore, also in this regard, the operator can easily secure the first frame side portion 52.

[0066] As shown in FIG. 13, after temporarily fixing the second frame side portion 62, the first frame side portion 52 is temporarily fixed as shown in FIG. 17. Therefore, with the already temporarily fixed second frame side portion 62 as a fulcrum, that is, with the lower part of the door body side portion 72 as a fulcrum, the operator can engage the first frame side portion 52, which is located at the upper part of the door body side portion 72, with the first holding portion 30 simply by sliding the first frame side portion 52 in the Y+ direction with respect to the first holding portion 30. Therefore, also in this regard, the operator can easily temporarily fix the first frame side portion 52.

[0067] As shown in FIG. 9, a second temporary fixing portion 40t protruding upward is provided at the lower portion of the second holding portion 40. A second portion to be temporarily fixed 62t that fits into the second temporary fixing portion 40t is provided at the lower portion of the second frame side portion 62. That is, the lower end portion of the second holding portion 40 and the lower end portion of the second frame side portion 62 have a fitting shape that fits together in the vertical direction. As shown in FIG. 13, due to the fitting by the fitting shape, the second frame side portion 62 is temporarily fixed to the second holding portion 40. Therefore, although the temporary fixing operation of the second frame side portion 62 is more difficult than that of the first frame side portion 52, the temporary fixing is difficult to come off. By first performing the temporary fixing of the second frame side portion 62 that is difficult to come off, and then performing the temporary fixing of the first frame side portion 52 where the temporary fixing operation is easy, these two temporary fixing operations can be efficiently carried out.

[0068] When removing the first latch 50, remove each screw Sb shown in FIG. 18 to release the permanent fixing of the first frame side portion 52 and the second frame side portion 62. In that state, as shown in FIG. 19, slide the first frame side portion 52 with respect to the first holding portion 30 to the Y-side, that is, the side opposite to the self-weight side in the Y direction. Thereby, the engagement between the first portion to be temporarily fixed 52t and the first temporary fixing portion 30t is released, and the temporary fixing of the first frame side portion 52 is released. Therefore, the temporary fixing of the first frame side portion 52 can be released by such a simple operation.

[0069] The operation of releasing the temporary fixing of the first frame side portion 52 shown in FIG. 19 is performed prior to the operation of releasing the temporary fixing of the second frame side portion 62 shown in FIG. 21. Therefore, when performing the operation of releasing the temporary fixing of the first frame side portion 52 shown in FIG. 19, the second frame side portion 62 is still temporarily fixed. By sliding the first frame side portion 52 located at the upper part of the door body side portion 72 to the Y-side with the still temporarily fixed second frame side portion 62 as a fulcrum, that is, with the lower part of the door body side portion 72 as a fulcrum, the engagement between the first portion to be temporarily fixed 52t and the first temporary fixing portion 30t can be released. After the engagement between the first portion to be temporarily fixed 52t and the first temporary fixing portion 30t is released and the temporary fixing of the first frame side portion 52 is released, the restraint on the door body 70 disappears except for the temporary fixing of the second frame side portion 62 shown in FIG. 21. Therefore, the operator can move the door body 70 relatively freely. Therefore, the operator can relatively easily release the temporary fixing of the second frame side portion 62.

[0070] [Other Embodiments] The above embodiments can be implemented with the following modifications, for example.

[0071] Contrary to FIG. 1, the first hinge attachment structure A1 may be on the lower side and the second hinge attachment structure A2 may be on the upper side. That is, the second hinge attachment structure A2 may be provided at the position of the first hinge attachment structure A1 shown in FIG. 1, and the first hinge attachment structure A1 may be provided at the position of the second hinge attachment structure A2 shown in FIG. 1. However, in this case, in the first hinge attachment structure A1 at the lower part of the door device 100, the self-weight side in the Y direction is the Y− side, not the Y+ side. Therefore, contrary to FIG. 4, when the first frame side portion 52 is slid to the Y− side with respect to the first holding portion 30, the first temporarily fixed portion 52t is temporarily fixed to the first temporary fixing portion 30t. Specifically, contrary to FIG. 4, the first temporary fixing portion 30t is provided at the Y− side end of the first holding portion 30. And the first temporarily fixed portion 52t is provided at the Y− side end of the first frame side portion 52.

[0072] The first hinge attachment structure A1 may be provided at both the upper and lower parts of the door device 100 shown in FIG. 1. That is, instead of the second hinge attachment structure A2 at the lower part of the door device 100 in FIG. 1, the first hinge attachment structure A1 may be provided. However, also in this case, for the lower first hinge attachment structure A1, contrary to FIG. 4, when the first frame side portion 52 is slid to the Y− side with respect to the first holding portion 30, the first temporarily fixed portion 52t is temporarily fixed to the first temporary fixing portion 30t.

[0073] Contrary to FIG. 6, the first temporary fixing portion 30t may be a protrusion protruding upward from the lower member 35c, and the first portion to be temporarily fixed 52t may be provided at the lower part of the first frame side portion 52. Further, the first portion to be temporarily fixed 52t may be a convex portion protruding toward the self-weight side in the Y direction, and the first temporary fixing portion 30t may be a concave portion engaging with the convex portion. Further, the first portion to be temporarily fixed 52t may be a concave portion recessed from the end portion on the self-weight side in the Y direction of the first frame side portion 52 toward the side opposite to the self-weight side in the Y direction, and the first temporary fixing portion 30t may be a convex portion engaging with the concave portion. Also in these cases, when the first portion to be temporarily fixed 52t and the first temporary fixing portion 30t slide the first frame side portion 52 toward the self-weight side in the Y direction with respect to the first holding portion 30, they engage with each other, and when they slide to the side opposite to the self-weight side in the Y direction, the engagement is released.

[0074] The pins 50 and 60 may be pins other than hidden pins such as flag pins. In addition to the first pin 50 and the second pin 60 shown in FIG. 1, another pin may be further attached to the side portion 72 of the door body shown in FIG. 1, and in addition to the first holding portion 30 and the second holding portion 40, another holding portion may be provided on the vertical frame 22. That is, the door device 100 may include three or more pins.

[0075] The first pin 50 shown in FIG. 6 may be a non-integral pin. That is, when attaching the door body 70 to the vertical frame 22, any one of the first frame side portion 52, the first connection portion 55, and the first door side portion 57 of the first pin 50 may be configured to be separable from the other portions. Similarly, the second pin 60 shown in FIG. 9 may also be a non-integral pin. However, as described above, in the above embodiments, even if the first pin 50 and the second pin 60 shown in FIG. 1 are integral pins, the side portion 72 of the door body can be attached to the vertical frame 22 without problems. Therefore, the first pin 50 and the second pin 60 are preferably integral pins.
