The repulsive force of the compression spring 61 is set to be weaker than the pulling force of the door body 13 by the closer 15, and the door body 13 is configured to be securely closed to the door frame 12 by the pulling force of the closer 15.

  Next, operation | movement of the door apparatus 11 of 1st Embodiment is demonstrated.

  As shown in FIGS. 1 (a) and 3 to 5, in the closed state where the door body 13 is closed to the door frame 12, the latch lock 29 of the door tip 13 b of the door body 13 is the side frame portion of the door frame 12. The door bottom 13a of the door body 13 is pulled into the non-shift position S1 by the pulling force of the closer 15, and the entire door body 13 is housed in the door body housing recess 23 of the door frame 12. In addition, the peripheral portion of the inner surface 13d of the door body 13 is in close contact with the packing 25 in a state where the packing 25 of the door contact portion 24 of the door frame 12 is crushed. Further, when the door body 13 is closed, a repulsive force toward the door opening side A of the door body 13 is accumulated in the compression spring 61. Further, the shift member 57 is set to a retracted position that is turned up and turned to the opposite door opening side B, and allows the door bottom 13a of the door body 13 to be accommodated in the door body accommodating recess 23 of the door frame 12. Yes.

  When opening the closed door body 13, when the handle 30 is operated and the latch lock 29 is released from the strike of the side frame portion 19 of the door frame 12, the door of the door body 13 is driven by the repulsive force of the compression spring 61. The tip 13b automatically moves to the door opening side A with the door bottom 13a side of the door body 13 supported by the hinge 14 as a fulcrum and opens slightly. Note that the door 13 is not necessarily automatically opened by the compression spring 61, but may be one that acts as an assist force when the door 13 is opened.

  Further, by pushing the door end 13b side of the door body 13 to the door opening side A, the door end 13b of the door body 13 is moved to the first hinge shaft 36 of the hinge 14 as shown in FIG. Is pivoted open to the door opening side A. As a result, the opening 22 of the door frame 12 is opened, and people and objects can enter and exit.

  Further, when closing the opened door body 13, by releasing the pushing operation of the door body 13 to the door opening side A, the door body 13 is pulled into the door frame 12 in the closing direction by the pulling force of the closer 15. Will automatically rotate and close.

  When the door body 13 is pulled by the closer 15, the torsion spring 47 as the shift means 46 attached to the second hinge shaft 37 of the hinge 14 causes the rotation side hinge portion 38 of the hinge 14 and the door body 13 to be connected. The shift position S2 is forcibly moved so that the shift position S2 is maintained, and the shift position S2 is maintained after the movement.

  Thus, since the rotation side hinge part 38 of the hinge 14 and the door body 13 are in the relationship of the shift position S2, when the door body 13 is closed, first, the door tip 13b of the door body 13 is moved to the door frame 12. The door body accommodating recess 23 is entered, and the packing 25 portion of the side frame portion 19 of the door frame 12 is crushed and stopped, and the latch lock 29 is locked to the strike of the side frame portion 19 of the door frame 12. In this state, as shown in FIG. 1 (b), the door bottom 13 a of the door body 13 is in a shift position S 2 where the door frame 13 is shifted to the outside of the door body housing recess 23. In FIG. 1 (b), the shift member 57 is in the restricted position where it is tilted to the door opening side A. However, in this description, the shift member 57 is moved to the counter door opening side B as shown in FIG. 1 (a). It is assumed that the door bottom 13a of the door body 13 is allowed to be accommodated in the door body accommodating recess 23 of the door frame 12 in the retracted position that is turned up.

  Subsequently, due to the pulling force of the closer 15, the door bottom 13a of the door body 13 enters the door body housing recess 23 of the door frame 12 and is pulled into the non-shift position S1, and the entire door body 13 is the door of the door frame 12. While being accommodated in the body accommodating recess 23, the entire peripheral portion of the inner surface 13d of the door body 13 is in close contact with the packing 25 in a state where the packing 25 of the door frame 12 is crushed. Further, when the door body 13 is closed, the door body 13 comes into contact with the compression spring 61, and the compression spring 61 is compressed by a part of the pulling force of the closer 15, and the door of the door body 13 is compressed to the compression spring 61. Accumulate repulsive force toward the opening side A.

  Therefore, when the door body 13 is closed, first, when the door tip 13b of the door body 13 is closed to the door frame 12, the door butt 13a of the door body 13 is in the shift position S2, and the door butt 13a of the door body 13 is Since a gap 64 is formed between the door frame 12 and the door contact portion 24 of the side frame portion 18 of the door frame 12, even when a finger or an object is caught in the gap 64, the finger or the object from the gap 64 before being caught Can be easily removed.

  Further, when the door body 13 is closed, first, the door tip 13b of the door body 13 is closed to the door frame 12, so that the door tip 13b of the door body 13 is used as a fulcrum, and the door body 13 is connected to a position near the door butt. Because the closer 15 causes the door bottom 13a of the door body 13 to be pulled from the shift position S2 to the non-shift position S1 that contacts the packing 25 of the door frame 12, that is, the door bottom 13a of the door body 13 is moved to the door frame 12. Since it becomes a movement that approaches almost parallel from the front side of the door stop 24, the pinching force between the door butt 13a of the door body 13 and the door stop 24 of the side frame 18 of the door frame 12 at this time is As compared with the conventional uniaxial hinge, it can be weakened compared to the strong clamping force generated by this principle, and even if a finger or an object is sandwiched, it does not matter.

  Moreover, when the door body 13 is opened, the door body 13 is set to a restricting position (a two-dot chain line position in FIGS. 1B and 1C and FIG. 2) where the shift member 57 is tilted to the door opening side A. When the door is closed, the door tip 13b of the door body 13 enters the door body housing recess 23 of the door frame 12, crushes and stops the packing 25 portion of the side frame portion 19 of the door frame 12, and the latch lock 29 is After being locked by the strike of the side frame portion 19 of the frame 12, the door bottom 13a of the door body 13 abuts on the shift member 57, and the door bottom 13a of the door body 13 is accommodated in the door body accommodating recess 23 of the door frame 12. In other words, the door bottom 13a of the door 13 is held at the shift position S2. As a result, a gap 64 is formed between the door butt 13a of the door body 13 and the door frame 12 so as to communicate with the door opening side A and the counter door opening side B, thereby ensuring ventilation. Even when the door body 13 is closed, the door bottom 13a of the door body 13 is shifted from the non-shift position S1 to the shift position S2 against the pulling force of the closer 15, and the shift member 57 is moved to the door opening side A. It can also be placed in a regulated position that has been defeated.

  Thus, according to the door device 11, the hinge 14 supports the door bottom 13a of the door body 13 so as to be rotatable with respect to the door frame 12, and the door tip 13b of the door body 13 is the door body of the door frame 12. While permitting the door butt 13a of the door body 13 to shift to the shift position S2 while being housed in the housing recess 23, the door of the door body 13 with the door butt 13a of the door body 13 being at the shift position S2 In order to allow the tip 13b to open and close with respect to the door body accommodating recess 23 of the door frame 12, when the door body 13 is closed, the gap between the door bottom 13a of the door body 13 and the door contact portion 24 of the door frame 12 A gap 64 can be formed on the door 13 to prevent fingers and objects from being pinched, and it can be prevented from being pinched strongly. Even when the door 13b of the door 13 is closed, the door butt 13a of the door 13 is shifted to the shift position. By shifting to S2, ventilation can be secured.

  Further, the door bottom 13a of the door 13 can be shifted in parallel to the shift position S2 by the biaxial hinge 14 having the first hinge shaft 36 and the second hinge shaft 37.

  Further, when the door body 13 is closed by the shift means 46, the door bottom 13a of the door body 13 can be forcibly shifted to the shift position S2, and pinching prevention and air permeability can be ensured. As the shift means 46, a biasing means for shifting, which is interposed between the rotation side hinge portion 38 of the hinge 14 and the door body 13, and biases the door bottom 13a of the door body 13 to shift to the shift position S2. Since the torsion spring 47 is provided as a body, when the door body 13 is closed, the door bottom 13a of the door body 13 can be forcibly shifted to the shift position S2. Note that the door body 13 is also closed by making the rotational resistance of the door body 13 relative to the first hinge shaft 36 of the hinge 14 greater than the rotational resistance of the door body 13 relative to the second hinge shaft 37 as the shift means 46. Sometimes the door bottom 13a of the door 13 can be forcibly shifted to the shift position S2.

  Further, when closing the door body 13, first, the door tip 13b of the door body 13 contacts the packing 25 of the door frame 12, and is locked to the door frame 12 by the latch lock 29 of the door tip 13b of the door body 13. As a result, the door bottom 13a of the door 13 is moved from the shift position S2 to the packing 25 of the door frame 12 by the closer 15 connected to the position near the door bottom of the door 13 with the door tip 13b of the door 13 as a fulcrum. The door body 13 and the packing 25 of the door frame 12 can be closely contacted with each other to increase the tightness and sound insulation, and the door body 13 can be opened. In some cases, the door tip 13b of the door body 13 that is separated from the connection position of the closer 15 can be opened with a light force. If the connecting position of the closer 15 in the door body 13 and the retracting force of the closer 15 are adjusted, the retracting force of the door bottom 13a can be increased without changing the operating force of the door tip 13b.

  Further, a repulsive force is accumulated in the compression spring 61 as an urging member for opening by the pulling force that closes the door body 13 by the closer 15, and the door tip 13 b side of the door body 13 is urged in the opening direction by the compression spring 61. Therefore, when the door body 13 is opened, the door tip 13b of the door body 13 can be opened with a light force.

  Also, the door tip 13b of the door body 13 is provided with a latch lock 29 that is engaged with the door frame 12 side, and the door body 13 is connected by the hinge 14 with the latch lock 29 engaged with the door frame 12 side. Since the door bottom 13a is allowed to shift to the shift position S2, it is possible to ensure ventilation while ensuring crime prevention.

  Moreover, since the conventional door device has a structure in which the packing is crushed and latched by the door body, a closer having a strong closing force is required, and the latching action (closing with the pattern) when closing the door body is large. There is no need for such a closer, and the door 13 can be quietly closed with a light operating force.

  For example, even when a door bolt 13 is provided with a dead bolt lock that engages and locks on the door frame 12 side, the dead bolt lock engages with the door frame 12 side. The door bottom 13a of the door body 13 is allowed to shift to the shift position S2 by the hinge 14 in a state in which the door 13 is in the air-tight state.

  Further, by moving the shift member 57 provided on the door frame 12 to the restriction position, the door bottom 13a of the door body 13 is restricted from being housed in the door body housing recess 23 at the position shifted to the shift position S2. In addition, by moving the door body 13 to the retracted position, the door bottom 13a of the door body 13 can be allowed to be received in the door body receiving recess 23 of the door frame 12, and the shift state of the door body 13 can be changed. Easy to change and set.

  In the first embodiment, the shift means 46 is not provided, and the rotational resistance of the door body 13 with respect to the first hinge shaft 36 of the hinge 14 is smaller than the rotational resistance of the door body 13 with respect to the second hinge shaft 37. Thus, the door body 13 can be opened and closed while the door bottom 13a of the door body 13 is positioned at the shift position S2 or the non-shift position S1. In this case, a handle is provided on at least the inner surface 13d of the door body 13, and the door butt 13a of the door body 13 is moved to the shift position S2 or the non-shift position S1 by the handle while the door body 13 is closed. That's fine. In this case, the closer 15 may not be provided. In this case as well, if the door butt 13a of the door body 13 is moved to the shift position S2, a gap 64 is provided between the door butt 13a of the door body 13 and the door frame 12 when the door body 13 is closed. Is formed, and pinching can be prevented and air permeability can be secured. In addition, when the door body 13 is moved to the non-shift position S1 with the door body 13 moved to the non-shift position S1, fingers and objects are caught between the door body 13a of the door body 13 and the door frame 12. However, the door bottom 13a of the door body 13 is shifted to the shift position S2, so that it is not pinched strongly, and it does not matter.

  Further, in the first embodiment, the shift means 46 is not provided, and the shift return bias that biases the hinge 14 in the direction in which the door bottom 13a of the door body 13 is returned from the shift position S2 to the original non-shift position S1. A body may be provided. In this shift return biasing body, instead of the torsion spring 47 as the shift biasing body in the first embodiment, the door bottom 13a of the door body 13 is returned from the shift position S2 to the original non-shift position S1. What is necessary is just to comprise with the torsion spring urged | biased to. Thereby, while allowing the door bottom 13a of the door body 13 to shift to the shift position S2, an opening / closing mode similar to that of a general door body can be adopted. In this case, the door bottom 13a of the door 13 can be closed to the door frame 12 without providing the closer 15.
