[0032]
Next, the operation of the door structure configured as described above will be described.
In the description of this operation, the door 1 is not in a state of being locked by the cylinder lock 5 or the thumb turn 6.
[0033]
First, when the door is closed, the door can be opened by a normal opening operation in a state where there is no pressure difference between the room and the room. That is, the door 1 can be opened by performing an operation of grasping and pulling the grip 2 outdoors and an operation of pushing the grip 2 indoors. In the operation of the grip 2, the link pieces 8 and 9 swing in conjunction with the moving direction of approaching or detaching with respect to the door surfaces 1 a and 1 b to operate the interlocking mechanism 10 in the lock box 13, thereby latch 12. When the door 1 is pulled together with the grip 2 on the outdoor side O, and the door 1 is pushed together with the grip 2 on the indoor side I, the latch 12 is disengaged from the strike plate 17 and released. Become.
[0034]
Next, when the door 1 is closed, it becomes difficult to open the door 1 due to a pressure difference between the room and the outside, and the lever 26 extending obliquely between the grip 2 and the door surfaces 1a and 1b. , 27 together with the grip 2. That is, the levers 26 and 27 are swung so as to follow the grip 2 (arrow A in FIG. 4).
[0035]
Then, as shown in FIGS. 5 and 7, in conjunction with the swinging of the lever 26 (27), the projecting rod 23 linked to this starts to advance. The tip 23 a of the protruding rod 23 that advances from the front plate 15 comes into contact with the roller 44 of the contact portion 41.
As the lever 26 (27) swings, the protruding rod 23 advances, and the inclined surface 23b at the tip of the protruding rod 23 comes into contact with the roller 44 of the contact portion 41 by this advancement, and the inclined surface 23b becomes the door by rotating the roller 44. It moves in the opening direction, that is, the door 1 itself is moved in the opening direction.
According to the configuration of the inclined surface 23b at the tip of the protruding collar 23 and the roller 44 of the abutting portion 41, the contact between each other becomes a line contact, and the roller 44 rotates so that the protruding collar 23 The advance movement can be assisted, and the movement of the door 1 in the opening direction can be made smooth.
[0036]
As a result, the gap between the edge of the indoor side surface 1a of the door 1 and the door stop 46 of the building side frame 42 can be opened, and from this, the distance between the edge of the door 1 and the door stop 46 C In this case, a gap of several mm to several tens of mm is generated in order to eliminate the pressure difference between the inside and outside of the room. In the present embodiment, the protruding rod 23 advances about 17 mm, and the inclined surface 23 b of the protruding rod 23 and the roller 44 of the contact portion 41 move the door 1 about 12 mm in the opening direction and only the swing operation of the lever 26. The opening of the door 1 can be started by an operation that does not require a large force.
[0037]
At the same time, by the swinging operation of the lever 26, the restriction state for the latch 12 is released via the interlocking mechanism 10 in the lock box 23 (see FIG. 7), and then the grip 2 is pulled from the outdoor side O. By pressing from the indoor side I, the latch 12 is reversed and retracted, and the door 1 is opened. Since the opening at this time is after the pressure difference is eliminated, the opening operation can be performed with a small force.
[0038]
That is, since the swing of the lever 26 is transmitted to the interlocking mechanism 10, the operation from the swing of the lever 26 to the opening of the door 1 can be performed smoothly, and when the door 1 is opened, the pressure difference is eliminated. Only the lever operation is added to the push-pull lock that facilitates the opening operation of the door without being aware of having an operation for the purpose, and the operation of the lever 26 is made to be aware that the door is opened. Can do.
[0039]
On the side of pulling the grip 2 that is the outdoor side O, the grip 2 is grasped and pulled together with the lever 26. However, by providing a universal joint 36 at the base end of the lever 26, as shown in FIG. As the grip 2 moves, the distal end side of the lever 26 swings and moves in a direction away from the door surface 1b, so that the movement of the grip 2 is not hindered and the door 1 can be opened smoothly.
[0040]
Therefore, in the door structure configured as described above, when the door 1 such as a front door in a high-rise house such as an apartment building has a pressure difference between the room and the outside, and it becomes difficult to open the door 1, By swinging the levers 26 and 27 in the vicinity of the grip 2 disposed on 1a and 1b, the protruding hook 23 is advanced from the mouth 1c of the door 1, and the protruding hook 23 is provided on the building side frame 42. The movement of the door 1 in the opening direction caused by contact with the contact portion 41 causes a gap C between the door edge and the edge on the building side, and the atmospheric pressure difference between the indoor and the outdoor Let go. Thereby, the opening difficulty by the pressure difference is eliminated, and the door 1 can be opened with a small force. In addition, it is not a special structure with a conventional window hole or the like, and since it does not use a complicated mechanism, it does not cause a decrease in airtightness or a crime prevention, and it can be easily achieved with a simple configuration. realizable.
[0041]
In the above-described embodiment, the example in which the inclined surface 23b is provided at the tip of the protruding rod 23 and the contact portion 41 including the roller 44 is provided on the building frame side 42 has been described. The contact portion 41 may have other configurations, for example, a rotatable roller may be provided at the tip of the protruding rod 23, and a slope may be provided on the building frame side 42.
In this case, the roller rolls along the slope as the tip of the protruding rod 23 advances, and thus the door 1 can be moved in the opening direction. This can be resolved when there is a pressure difference.
[0042]
Further, in the embodiment described above, the universal joint 36 is provided at the base end of the lever 26 so that it can swing in a direction parallel to the door surface 1b and swings in the disengagement direction with respect to the door surface 1b. An example in which the lever 26 can be freely moved with the movement of the grip 2, and the interlocking mechanism 10 and the lever 26 are interlocked to transmit the swing of the lever 26 to the interlocking mechanism 10. As described above, since the gap C between the edge of the door 1 and the door stop 46 on the building side is generated only by the swinging operation parallel to the door surface 1b of the lever 26, the universal joint as described above. Even without the configuration of 36 or the configuration of interlocking connection with the interlocking mechanism 10, the same effect as described above that can eliminate the atmospheric pressure difference between the inside and outside of the room can be obtained.
[0043]
