  A mounting structure for rotatably mounting the door 100 to the door frame 110 is formed using the lower hinge device A, the lower mounting base 60, the upper hinge device B, and the upper mounting base 80 described above.

  Specifically, the door 100 is attached as described below. First, the frame side mounting base 63 of the lower side mounting base 60 is screwed to the lower part of the inner side surface of the door frame 110. At this time, the lower mounting base 60 is provided so that the lower surface of the mounting table 72 is in contact with the floor surface (see FIG. 11). The frame-side mounting base 63 of the upper mounting base 80 is fixed to the upper part of the inner side surface of the door frame 110 with screws. The lower mounting base 60 and the upper mounting base 80 fixed to the door frame 110 are arranged so that the basic configuration is turned upside down.

The lower hinge device A and the upper hinge device B fixed to the door 100 are arranged so that the basic configuration is turned upside down.

  Here, the movable blocks 2 of both the lower hinge device A and the upper hinge device B are set in a state of being rotated by a predetermined angle (for example, 90 °) with respect to the fixed block 1. In this state, the left and right end portions of the door 100 are lifted, and the fixed block 1 of the lower hinge device A is first placed on the upper surface of the mounting table 72 of the lower mounting base 60. At this time, the engaged portion (that is, the lower portion of the position adjusting shaft 23) that protrudes downward from the fixed block 1 is inserted into the recessed groove of the positioning engaging portion 73 provided on the mounting table 72, thereby positioning the door 100. Is made.

  By using the positioning portion as a fulcrum, the entire door 100 is pushed into the door frame 110 side, so that the frame side connector 14 provided in the lower hinge device A is provided between the pair of locking claw pieces 69 provided in the lower mounting base 60. The vertical plate 13 is elastically locked. Similarly, the vertical plate 13 of the frame side connector 14 included in the upper hinge device B is elastically locked between the pair of locking claw pieces 69 provided in the upper mounting base 80. That is, the entire door 100 is temporarily held by the door frame 110 through these attachment structures by the operation of pushing the entire door 100 with the positioning engagement portion 73 as a fulcrum.

  In this temporary holding state, the door 100 is permanently fixed to the door frame 110 via the mounting structure. Specifically, a fixing screw 68 is inserted from a position fixing hole 28 provided in the vertical plate 13 of the frame side connector 14 provided in the lower hinge device A, and this is screwed into a deformed nut 75 of the lower mounting base 60. Let As a result, the frame side connector 14 of the lower hinge device A is fixed to the lower mounting base 60. Similarly, in the upper hinge device B, the frame-side connector 14 of the upper hinge device B is fixed to the upper mounting base 80 by inserting the fixing screw 68 from the position fixing hole 28 and screwing it into the deformed nut 75. The

  That is, in the lower mounting base 60 and the upper mounting base 80, the pair of locking claw pieces 69 function as a temporary holding structure, and the nut hole 66 and the deformed nut 75 fitted therein function as the main fixing structure. .

  As described above, in the mounting structure of the present embodiment, by using the temporary holding structure and the main fixing structure provided on the lower mounting base 60 and the upper mounting base 80, the door 100 can be used even if there is only one worker. Can be easily attached.

  Here, an opening / closing operation of the door 100 attached to the door frame 110, that is, an opening / closing operation of the lower hinge device A and the upper hinge device B will be described. The basic operation of the lower hinge device A and the upper hinge device B of the present embodiment is the same as that described in Japanese Patent Application Laid-Open No. 2005-146625. When the door 100 is in the fully closed position, FIG. As shown, the fixed block 1 and the movable block 2 are completely overlapped.

  In the fully closed position of FIG. 1, the tip end portion of the first locking pin 35 protruding downward from the intermediate block 3 is located at the suspension side end of the first arc-shaped long hole 26 of the fixed block 2. Further, the tip end portion of the second locking pin 36 protruding upward from the intermediate block 3 is positioned at the end of the bent portion 49 of the second arc-shaped elongated hole 48 of the door side block 4.

  When the door 100 is opened from the fully closed position, the door block 4 does not rotate around the second rotation shaft 6 but rotates around the first rotation shaft 5 with respect to the fixed block 1 integrally with the intermediate block 3. . This is because the second locking pin 36 is located at the end of the bent portion 49 of the second arcuate long hole 48. The intermediate block 3 including the interlocking arm 37 and the door-side block 4 rotate around the first rotation shaft 5 while being overlapped. At this time, the first locking pin 35 slides in the first arc-shaped long hole 26. Then, at the position of the specified angle shown in FIG. 7, the first locking pin 35 comes into contact with the intersecting portion between the first arc-shaped long hole 26 and the bent portion 27, and the intermediate block 3 stops rotating.

  When the door 100 is further opened from the state of FIG. 7, the intermediate block 3 cannot be rotated any further, and thus a force to rotate around the second rotation shaft 6 acts on the door side block 4. By this force, the bent portion 49 of the second arc-shaped long hole 48 pushes out the second locking pin 36 and rotates the interlocking arm 37 to the intersection of the second arc-shaped long hole 48 and the bent portion 49. The second locking pin 36 is moved. That is, the rotation lock of the door side block 4 with respect to the intermediate block 3 is released, and the door side block 4 is rotatable about the second rotation shaft 6 with respect to the intermediate block 3. At this time, the first locking pin 35 slides to the end of the bent portion 27 of the first arc-shaped elongated hole 26 by the rotation of the interlocking arm 37, and locks the rotation of the intermediate block 3 relative to the fixed block 1. The door side block 4 is rotated 90 ° as it is to the position shown in FIG.

  To summarize the above operation, the interlock arm 37 does not operate with respect to the intermediate block 3 from the fully closed position in FIG. 1 to the specified angle as shown in FIG. The intermediate block 3 and the door-side block 4 rotate integrally around the first rotation shaft 5 while sliding in the arc-shaped long hole 26. If a force is further applied in the direction of rotation from the specified angle, the interlocking arm 37 rotates with respect to the intermediate block 3, locks the rotation of the intermediate block 3 with respect to the fixed block 1, and rotates the door side block 4 with respect to the intermediate block 3. unlock. That is, only the door side block 4 rotates further about the second rotation shaft 6.

  These structures constitute the rotation restricting mechanism of the present embodiment. This rotation restricting mechanism prohibits the rotation of the door block 4 around the second rotation axis 6 until the rotation of the intermediate block 3 around the first rotation axis 5 reaches a specified angle, and if the rotation reaches the specified angle, the second rotation. This enables rotation around the axis 6. You may implement | achieve this rotation control with another mechanism.

  When the door 100 is closed from the fully opened state shown in FIG. 8, each member operates in the reverse order of the above operation. That is, first, only the door side block 4 rotates while the intermediate block 3 is rotationally locked with respect to the fixed block 1. When the door side block 4 reaches the position where it overlaps the intermediate block 3, this time, the door side block 4 is rotationally locked with respect to the intermediate block 3, and the intermediate block 3 and the door side block 4 rotate integrally with the fixed block 1. To do.

  Next, the structure and procedure for adjusting the position of the door 100 in a state of being attached to the door frame 110 will be described.

  In the present embodiment, as described above, the fixed block 1 provided in each of the lower hinge device A and the upper hinge device B includes the cam mechanism that adjusts the left and right positions of the movable block 2 and thus the door 100 by the rotation of the cam plate 16. ing. Further, the lower mounting base 60 and the upper mounting base 80 are provided with a cam mechanism that adjusts the front-rear position of the door 100 by the rotation of the cam plate 65. The mounting table 72 of the lower mounting base 60 is provided with an elevating mechanism for adjusting the vertical position of the door 100. Hereinafter, these position adjusting mechanisms will be described in order.

  The cam mechanism for adjusting the left / right position inserts the tip of the driver into the cross groove of the cam plate 16 through the position adjustment windows 17 and 18 of the fixed block 1 and rotates the cam plate 16 to move the position adjustment plate 7 in the left / right direction. The position is adjusted. The left and right cam operation portions including the position adjusting windows 17 and 18 and the cross groove are covered with the intermediate block 3 and the door side block 4 and cannot be operated in the fully closed position shown in FIG. Further, the fixed operation portion including the fixed operation windows 21 and 22 and the fixing screw 19 is also covered with the intermediate block 3 and the door side block 4 and cannot be operated in the fully closed position of FIG.

  On the other hand, when the intermediate block 3 and the door side block 4 reach a specified angle in FIG. 7 beyond a predetermined angle from the fully closed position, the cam operation unit and the fixed operation unit are provided so as to be exposed. When adjusting the left-right position, the door 100 is opened to expose the cam operation unit and the fixed operation unit, and first the fixing screw 19 of the fixed operation unit is loosened to release the fixed state. After that, the tip of the driver is inserted into the cross groove of the cam operating portion, and the cam plate 16 is rotated to adjust the left-right position, and the fixing screw 19 is tightened again to fix the left-right position.

  The cam mechanism for front / rear position adjustment inserts the tip of the driver into the cross groove of the cam plate 65 through the position adjustment window 29 of the frame side connector 14 and rotates the cam plate 65 to thereby adjust the position adjustment plate 61 and the position adjustment. The position of the spacer 62 is adjusted in the front-rear direction. These position adjustment windows 29 and the position adjustment portion in the front-rear direction formed by the cross groove are hidden behind the door 100 and cannot be operated in the fully closed position of FIG.

  On the other hand, when the intermediate block 3 and the door-side block 4 exceed the predetermined angle from the fully closed position and reach the specified angle in FIG. 7, the cam operation part in the front-rear direction is provided to be exposed. Therefore, when adjusting the front / rear position, the front / rear direction cam operation part is exposed by opening the door 100, the driver tip is inserted into the cross groove of the cam operation part, and the cam plate 65 is rotated to rotate the front / rear position. Make adjustments.

  The elevating mechanism for adjusting the vertical position is a metal member that forms the positioning engagement portion 73 by inserting and rotating the tip of the driver into the cross groove of the vertical adjustment screw 74 provided on the mounting table 72 of the lower mounting base 60. Is moved up and down to adjust the vertical position.

  As described above, according to the mounting structure of the present embodiment, the front / rear, left / right, and vertical position adjustment can be easily performed even if there is only one worker. In particular, after the load of the door 100 is received by the facing surface between adjacent blocks 1, 3, 4, the cam plate 16 is rotated around the vertical axis in the fixed block 1, and the position adjustment plate portion Since the position can be adjusted by moving 10 in the horizontal direction, the position can be adjusted with a small force.

  In the present embodiment, the cam mechanism in the fixed block 1 is used for left-right position adjustment, but may be provided so as to be used for front-rear position adjustment. Further, the fixed block 1 may be provided with both a left-right position adjusting cam mechanism and a front-rear position adjusting cam mechanism.

  Next, the structure and procedure for removing the door 100 from the door frame 110 will be described.

  In the present embodiment, as described above, the temporary holding release piece 50 is provided in the frame-side connector 14 included in the fixing block 1 of the lower hinge device A, thereby releasing the lower hinge device A from the temporary holding state. Means. Similarly, also in the upper hinge device B, by providing the temporary holding release piece 50 in the frame side connector 14 included in the fixed block 1, a releasing means for releasing the upper hinge device B from the temporary holding state is configured.

  In the fully closed position in FIG. 1, the release operation unit 70 formed of a cross groove for rotating the temporary holding release piece 50 is hidden behind the door 100 and cannot be operated. On the other hand, when the intermediate block 3 and the door block 4 exceed the predetermined angle from the fully closed position to the specified angle of FIG. 7, and when the door 100 is further opened to reach the fully open position of FIG. The operation unit 70 is provided so as to be exposed. In addition, as shown in FIG. 8, in the fully open state, the door side block 4 is located ahead (the direction which opens the door 100) rather than the fixed block 1, and it is provided so that it may face the reverse direction.

  When removing the door 100, the door 100 is opened to expose the fixing screw 68 and the release operation unit 70, the fixing screw 68 is removed to release the main fixing, and the driver tip is inserted into the cross groove of the release operation unit 70. And the temporary holding release piece 50 may be rotated. The rotated temporary holding release piece 50 pushes the claw portion of the locking claw piece 69 outward to release the temporary holding state. And the door 100 can be easily removed by moving the whole door 100 by using the positioning engagement part 73 as a fulcrum.
