  By operating the glemon handle 50 to lower the lock rod 56 to the lowermost position of the movement range by operating the glemon handle 50, the lock rod 56 is projected from the door end material 12 as shown in FIG. The rubber sheet 56a is brought into contact with the floor 4 below the door 1 which is a portion facing the door 1 to restrict the rotation of the door 1. Here, the lock rod 56 is provided so as to be able to project downward, and corresponds to a projecting support member capable of projecting and abutting a portion facing the door body and supporting the door body. Further, the lowermost position of the movement range by the operation of the Gremont handle 50 corresponds to the contact position where the protruding support member is in contact with the portion facing the door body.

  In the magnet latch 55, a pedestal 55a fixed to the upper end of the upper connecting rod 53 projects inward from the indoor wall portion 13a, and the magnet 55b is exposed on the indoor surface of the pedestal 55a. A pedestal projecting piece 55c that projects downward from the lower surface of the pedestal 55a is provided at a position spaced apart from the indoor wall 13a in the prospective direction.

  A metal latch receiver 57 is fixed to the opening side wall edge portion 2b of the wall 2, and the magnet latch 55 is kept in contact with the magnetic latch 55 to maintain the contact state. The latch receiver 57 extends along the outer surface of the opening side wall edge portion 2b from the outdoor side edge of the latch receiver fixing portion 57a fixed to the inner peripheral surface of the opening side wall edge portion 2b. The latch receiving extension 57b that has been extended, the latch receiving lower extension 57c that extends from the lower end of the latch receiving extension 57b to the outside of the room, and the upper edge of the outside of the latch receiving lower extension 57c And a latch receiving upward extension portion 57d extended to the.

  When the latch receiver 57 provided on the wall 2 side is located at the uppermost position of the movement range by the operation of the Gremont handle 50, as shown in FIG. 5, the pedestal projecting piece 55c is more than the latch receiving upward extending portion 57d. The latch receiving extension 57b is arranged so as to be located at a high position, and when the door 1 is closed, the magnet 55b of the magnet latch 55 abuts the latch receiving extension 57b to open the door 1. The closed state of 2a is maintained. Then, by operating the Gremont handle 50 to lower the magnet latch 55 and moving it to the lowest position in the moving range, the pedestal projecting piece 55c extends the latch receiving extension 57b and the latch receiving upward as shown in FIG. The door 1 is inserted into the protruding portion 57d, and the movement of the door tip portion of the door 1 to the outside of the door is restricted and locked. In the present embodiment, the magnet 55b corresponds to the closing maintaining member, the latch receiving extending portion 57b corresponds to the engaging portion with which the closing maintaining member is engaged, and the pedestal projecting piece 55c corresponds to the locking member.

  In the door 1 of the present embodiment, when the magnet latch 55 and the lock rod 56 are located at the uppermost position of the movement range by the operation of the Gremont handle 50, the pedestal projecting piece 55c of the magnet latch 55 is located above the latch receiving upward extending portion 57d. Is located at a higher position, the lock bar 56 is separated from the floor 4 facing the door 1 below and is openable and closable. Here, the uppermost position of the movement range by the operation of the Gremont handle 50 corresponds to the separated position where the protruding support member is separated from the portion facing the door body.

  When the door 1 is closed in this state, the opening 2a can be maintained in the closed state by the magnetic force of the magnet latch 55, and the magnet latch 55 and the lock rod 56 are closed when the door 1 is closed. When the Glemon handle 50 is moved to the lowest position in the movement range, the lock rod 56 restricts the rotation of the door and the locking mechanism 5 locks the door 1. Further, even when the magnet latch 55 and the lock rod 56 are moved to the lowermost position of the movement range by the operation of the Gremont handle 50 with the door 1 opened, the abutting plate portion 56c of the lock rod 56 is placed on the floor. The door 1 is restricted from rotating by coming into contact with the door 4.

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, first, as shown in FIG. The hinge fixing portion 3b of the pivot hinge 3 is fixed to the lower end of the peripheral surface (lower hinge fixing step). At this time, the pivot hinge 3 is arranged so that the pin 3a is located outside the room.

  Further, the latch receiver fixing portion 57a of the latch receiver 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 tip side of the door 1 in the opening 2a of the wall 2 (fixing engagement portion). Process). At this time, the latch receiving extension portion 57b is arranged along the surface of the opening side wall edge portion 2b on the outdoor side. At this time, either the lower hinge fixing step or the engaging portion fixing step may be performed first.

  Next, the door 1 provided with the locking mechanism 5 is made to stand on the outside of the opening side wall edge portion 2b of the wall 2 (door body self-standing process). More specifically, by operating the Gremont handle 50 to move the lock rod 56 to the lowest position in the range of movement by operating the Gremont handle 50, the lock rod 56 projects below the lower end of the vertical member 13 on the door end side. I will let you. At this time, the magnet latch 55 connected to the lock bar 56 by the link bar 52 is also located at the lowermost position of the movement range by the operation of the Gremont handle 50.

  The door 1 with the lock bar 56 protruding is moved to the outside 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 portion 2b is located on the side from which the door 1 is suspended. The door 1 is lowered from above so as to be inserted into the hinge receiver provided at the lower end of the vertical member 13. At this time, the door 1 is lowered from above the pin 3a while being substantially parallel to the wall 2.

  The pin 3a is inserted into the hinge receiver, the lock bar 56 is brought into contact with the floor 4, and the pedestal projecting piece 55c of the magnet latch 55 is located between the latch receiving extension 57b and the latch receiving upward extension 57d. Inserted in. At this time, the door 1 is supported by the lower pivot hinge 3 and the lock rod 56, the pedestal projecting piece 55c engages with the latch receiving upward extending portion 57d, and the magnet 55b of the magnet latch 55 receives the latch receiving extending portion. Since it is abutted against 57b and attracted, 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-supporting door 1 to mount the pivot hinge 3 on the vertical member 13. Place. The mounted pivot hinge 3 rotates the hinge plate 3d about 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. The door 1 is fixed and the attachment of the door 1 to the wall 2 is completed (upper hinge fixing step).

  According to the door 1 of the present embodiment, the door 1 is moved to a desired position because it has the lock bar 56 that projects downward and contacts the floor 4 facing the door 1 and can support the door 1. After that, the lock rod 56 is made to project downward and abut against the floor 4, so that it is possible to easily maintain the state where the door 1 is open at a desired position. Further, since the lock bar 56 supports the door 1, the weight of the door 1 acts and the frictional force generated between the lock bar 56 and the floor 4 allows the door 1 to be more reliably positioned 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, the rotation of the door 1 can be restricted by a higher frictional force.

  Further, the door 1 is supported on the wall 2 by the pivot hinges 3 on the upper end side and the lower end side on the suspension base side which is one end in the width direction. Therefore, for example, it is possible to make the door 1 self-supporting by the pivot hinge 3 on the lower end side and the protruding lock bar 56. Therefore, it is possible to attach the pivot hinge 3 on the upper end side in a state where the door 1 is self-supporting after the door 1 with the lock rod 56 protruding is engaged with the pivot hinge 3 on the lower end side. That is, since the upper-side pivot hinge 3 and the lower-side pivot hinge 3 are not engaged at the same time, they can be easily engaged with the lower-side pivot hinge 3, and after engaging with the lower-end pivot hinge 3. 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 with better workability.

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

  Further, since the pedestal projecting piece 55c is locked by being engaged with the latch receiver 57 provided on the wall 2 side when the lock lemon 56 is moved to the abutting position by operating the Gremont handle 50, the lock rod 56 is locked. It is possible to lock the door 1 while restricting its movement. Further, when the Gremont handle 50 is operated to move the lock rod 56 to the separated position, the engagement between the pedestal projecting 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 method of constructing the door 1 described above, the door 1 with the lock rod 56 protruding 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. Then, the magnet latch 55 is brought into contact with the latch receiver 57 at the upper portion of the door 1 and the pedestal projecting piece 55c is engaged with the latch receiver 57 to lock the door 1 so that the door 1 can be made independent. Therefore, the heavy door 1 does not have to be supported after being easily engaged with the pivot hinge 3 on the lower end side and engaged with the pivot hinge 3 on the lower end side, so that the burden on the operator can be reduced. At this time, the upper portion of the door 1 is maintained in the state in which the door 1 closes the opening 2a by the magnet latch 55 and the pedestal projecting piece 55c, so that the door 1 can be more reliably made to stand by itself.

  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 by itself, it is possible to easily fix the pivot hinge 3 on the upper end side. Therefore, the burden on the operator is small and the door 1 can be easily attached.

  In the above embodiment, the magnet 55b is used as the closing maintaining member and the pedestal projecting piece 55c is used as the locking member, but the present invention is not limited to this. For example, a magnet is not provided, the pedestal projecting piece 55c and the latch receiving upward extending portion 57d serve as a closing maintaining member and a locking member, and the pedestal projecting piece 55c is engaged with the latch receiving upward extending portion 57d. At this time, the door 1 may be configured to maintain the state in which the opening 2a is closed.

  In addition, in the above-described embodiment, the projecting support member can be moved to the contact position and the separation position by operating the Glemont handle 50 that is gripped when the door 1 is opened and closed, and the locking member is used as an operable operation unit. Although an example has been described, the present invention is not limited to this. For example, as shown in FIG. 8, the opening / closing operation unit 6 held by the operator when opening / closing the door 1 and the lock rod 56 can be moved to the contact position and the separation position, and the pedestal projecting piece 55c can be operated. The operation unit 7 may be provided separately. In this case, in the operation unit 7, the pinion 7b provided on the rotary shaft 7a along the prospective direction meshes with the rack 51a of the vertical movement member 51, as in the Gremont handle 50 of the above embodiment.

  By separately providing the opening / closing operation unit 6 and the operation unit 7 in this way, the operation unit 7 is made smaller than the Gremont handle 50, and the opening / closing operation unit 6 is a digging puller recessed from the surface of the door 1. As a result, the amount of protrusion from the surface of the door 1 can be reduced and the weight can be reduced.

  The above embodiment is for facilitating the understanding of the present invention, and is not for limiting the interpretation of the present invention. It goes without saying that the present invention can be modified and improved without departing from the spirit thereof and that the present invention includes equivalents thereof.
