By abutting on 4, the rotation of the door 1 is restricted.

The construction method of the door 1 of this embodiment will be described.
When the door 1 is attached to the opening side wall edge 2b of the wall 2, as shown in FIG. 7, first, in the opening 2a of the wall 2, the inside of the opening 2a forming the opening side wall edge 2b on the hanging side of the door 1. The hinge fixing portion 3b of the pivot hinge 3 is fixed to the lower end portion of the peripheral surface (lower hinge fixing step). At this time, the pivot hinge 3 is arranged so that the pin 3a is located on the outdoor side.

Further, the latch receiving fixing portion 57a of the latch receiving 57 is fixed to the upper end side of the inner peripheral surface of the opening 2a forming the opening side wall edge portion 2b on the door end side of the door 1 in the opening 2a of the wall 2 (engagement portion fixing). Process). At this time, the latch receiving extension portion 57b is arranged along the outdoor surface of the opening side wall edge portion 2b. At this time, it does not matter which of the lower hinge fixing step and the engaging portion fixing step comes first.

Next, the door 1 provided with the locking mechanism 5 is made to stand on the outdoor side of the opening side wall edge portion 2b of the wall 2 (door body independence step). More specifically, by operating the Gremon handle 50 to move the lock rod 56 to the lowest position of the movement range by operating the Gremon handle 50, it protrudes downward from the lower end of the vertical member 13 on the door end side. Let me do it. At this time, the magnet latch 55 connected to the lock rod 56 by the link bar 52 is also located at the lowest position of the movement range by the operation of the Gremon handle 50.

The door 1 with the lock rod 56 projected is moved to the outdoor side of the wall 2 and the opening 2a, and the pin 3a of the lower pivot hinge 3 fixed to the opening side wall edge 2b is on the hanging side of the door 1. The door 1 is lowered from above so as to be inserted into the hinge holder provided at the lower end of the vertical member 13. At this time, the door 1 is lowered from above the pin 3a in a state of being substantially parallel to the wall 2.

The pin 3a is inserted into the hinge holder, the lock rod 56 is brought into contact with the floor 4, and the pedestal protruding piece 55c of the magnet latch 55 is between the latch receiving extension portion 57b and the latch receiver upper extension portion 57d. Will be inserted into.

Since it is attracted to the 57b, the movement of the upper side of the door 1 to the outdoor side is restricted, so that the door 1 becomes independent.

Next, the pin 3a of the upper pivot hinge 3 is inserted into the hinge receiver provided at the upper end of the vertical member 13 on the hanging side of the self-standing door 1, and the pivot hinge 3 is placed on the vertical member 13. Place. In the mounted pivot hinge 3, the hinge plate 3d is rotated around the pin 3a so that the hinge fixing portion 3b faces the upper end portion of the inner peripheral surface of the opening 2a forming the opening side wall edge portion 2b. After fixing, the attachment of the door 1 to the wall 2 is completed (upper hinge fixing process).

According to the door 1 of the present embodiment, since the door 1 has a lock rod 56 that protrudes downward and abuts on the floor 4 facing the door 1 and can support the door 1, the door 1 is moved to a desired position. By projecting the lock rod 56 downward and bringing it into contact with the floor 4, it is possible to easily maintain the door 1 open at a desired position. Further, since the lock rod 56 supports the door 1, the weight of the door 1 acts on the lock rod 56, and the frictional force generated between the lock rod 56 and the floor 4 causes the door 1 to be more reliably placed at a desired position. It is possible to keep it open. In particular, since the rubber sheet 56a is provided on the lower surface of the lock rod 56, it is possible to regulate the rotation of the door 1 by a higher frictional force.

Further, the door 1 is supported by the wall 2 by the pivot hinge 3 on the upper end side and the lower end side on the hanging side which is one end in the width direction. Therefore, for example, the door 1 can be made to stand on its own by the pivot hinge 3 on the lower end side and the protruding lock rod 56. Therefore, after the door 1 on which the lock rod 56 is projected is engaged with the pivot hinge 3 on the lower end side, it is possible to attach the pivot hinge 3 on the upper end side while the door 1 is self-supporting. That is, since the pivot hinge 3 on the upper end side and the pivot hinge 3 on the lower end side are not engaged at the same time, they can be easily engaged with the pivot hinge 3 on the lower end side, and after engaging with the pivot hinge 3 on the lower end side, Since the pivot hinge 3 on the upper end side can be fixed without supporting the door 1, it is possible to provide the door 1 having more excellent workability.

Further, since the magnet latch 55 that causes the door 1 to face the wall 2 and keeps the opening 2a in a closed state is provided on the upper part of the door end side that is the other end in the width direction, it faces the wall 2. It is possible to prevent the door 1 from falling over. Further, since the door 1 is maintained in a closed state by the magnetic force of the magnet latch 55, the opening 2a can be maintained in a closed state even if the door 1 is not attached at an accurate position. It is possible.

Further, when the lock rod 56 moves to the contact position by operating the Gremon handle 50, the pedestal projecting piece 55c engages with the latch receiver 57 provided on the wall 2 side and is locked, so that the lock rod 56 is locked. It is possible to lock the door 1 while restricting its movement. Further, when the lock rod 56 is moved to the separated position by operating the Gremon handle 50, the engagement between the pedestal protruding piece 55c and the latch receiver 57 is released. Therefore, when the lock is released, the restriction on the rotation of the door 1 is also released, so that the door 1 can be easily opened.

Further, according to the construction method of the door 1, the door 1 having the lock rod 56 projected is engaged with the lower pivot hinge 3 in a state where the lower pivot hinge 3 and the latch receiver 57 are attached to the wall 2. The door 1 can be made to stand on its own by locking the door 1 by bringing the magnet latch 55 into contact with the latch receiver 57 at the upper part of the door 1 and engaging the pedestal projecting piece 55c with the latch receiver 57. Therefore, it is not necessary to easily engage with the pivot hinge 3 on the lower end side and support the heavy door 1 after engaging with the pivot hinge 3 on the lower end side, so that the burden on the operator can be reduced. At this time, since the upper part of the door 1 is maintained in a state where the door 1 is closed with the opening 2a by the magnet latch 55 and the pedestal projecting piece 55c, the door 1 can be made to stand on its own more reliably.

Since the pivot hinge 3 on the upper end side is fixed in a state where the door 1 closes the opening 2a and stands on its own, the pivot hinge 3 on the upper end side can be easily fixed. Therefore, the burden on the operator is small and the door 1 can be easily attached.

In the above embodiment, an example in which the magnet 55b is used as the closing maintenance member and the pedestal protruding piece 55c is used as the locking member has been described, but the present invention is not limited to this. For example, no magnet is provided, the pedestal projecting piece 55c and the latch receiving upward extending portion 57d also serve as a locking member and the locking member, and the pedestal projecting piece 55c engages with the latch receiving upward extending portion 57d. Occasionally, the door 1 may be configured to remain closed with the opening 2a.

Further, in the above embodiment, the protruding support member can be moved to the contact position and the separated position by operating the Gremon handle 50 gripped when the door 1 is opened and closed, and the locking member is used as an operable operation unit. An example has been described, but it is not limited to this. For example, as shown in FIG. 8, the opening / closing operation unit 6 gripped by the operator when opening / closing the door 1 and the lock rod 56 can be moved to the contact position and the separated position, and the pedestal protruding piece 55c can be operated. The operation unit 7 may be provided separately. In this case, the operation unit 7 has the pinion 7b provided on the rotation shaft 7a along the prospective direction meshing with the rack 51a of the vertically moving member 51, similarly to the Gremon handle 50 of the above embodiment.

By providing the opening / closing operation unit 6 and the operation unit 7 separately in this way, the operation unit 7 is made smaller than the Gremon handle 50, and the opening / closing operation unit 6 is used as a digging puller recessed from the surface of the door 1. This makes it possible to reduce the amount of protrusion of the door 1 from the surface and reduce the weight.
