Description

[Detailed Description of the Invention] Industrial Application Field The present invention is an opening/closing door device for partitioning indoor and outdoor areas, and is a piece having an opening/closing door in a door frame and a single locking device at the upper and lower intermediate portions of the opening/closing door. It relates to an opening/closing door system, such as a double door system, in which the opening or one door is integral with the door frame, usually with a French drop or the like.

Prior Art Conventionally, such an opening/closing door device can be described as a double door device.As shown in Figs. It is hinged so that it opens to the outside. The child door 3 is normally attached to the door frame 1 by means of well-known French traps 5, 5 disposed above and below within the door frame 4.
It is integrated with the main door 2, and only the main door 2 can be opened and closed. A locking device 7 is attached to the upper and lower intermediate portions of the connecting frame 6 of the main door 2, and the locking device 7 is locked when the door is to be locked at night or when going out. Further, the door frame 1 has protrusions 15 on its upper and lower, left and right frames 11 to 14, and an airtight material 16 is attached to the outdoor side of the protrusions 15.

Problems to be Solved by the Invention According to the conventional opening/closing door device, for example, in the case of a typhoon, large positive pressure (pressure in the direction of closing the main door 2) is applied from outside to the outer surface of the main door 2 due to wind pressure. When the upper and lower frames 8 and 9 of the main door 2 and the hanging vertical frame 10 are pressed against the airtight material 16 of the upper and lower frames 11 and 12 and the left frame 13, the connecting frame 6 of the main door 2 The upper and lower parts are completely prevented from bending. However, when the pressure from outside becomes a large negative pressure or when pressure is applied from inside the room, the main door 2 has its connecting stile 6 locked in one place by the fixed child door 3 and the locking device 7. Since they are only connected, using this as a fulcrum, the upper and lower ends of the stile 6 will bend greatly toward the outside, causing plastic deformation of the material, and a large gap will be created between the main door 2 and the door frame 1, allowing rain and wind to leak out. There was a fear that someone might come in.

The object of the present invention is to provide a deflection prevention device for an opening/closing door device that prevents a gap from forming between the door frame and the stile even if a large force is applied to the closed door to open it toward the outside. shall be.

Means for Solving the Problems The present invention is an opening/closing door device that partitions indoors and outdoors, in which the opening/closing door is hinged to the door frame so as to open from the closed state to the outside of the room, and the lock side stile of the opening/closing door is Up,
A locking device between the fixed door member and the lower middle part is installed.
In an opening/closing door device equipped with a lock side stile of the opening/closing door, one member of a fixed door member that faces the lock side stile in a closed state in the left and right direction orthogonal to the indoor/outdoor direction includes a door frame. A receiving part having a receiving surface capable of receiving the opening direction force toward the outdoor side of the opening/closing door at the upper part close to the upper frame and the lower part close to the lower frame of the door frame is provided inside the member or on the inner side surface of the member, The other member is characterized in that an engaging member that can be engaged with and detached from the receiving surface from the indoor side is disposed at a position facing the receiving portion in the left-right direction in the closed state.

Function According to the above configuration, in addition to engaging the locking device, by engaging the engaging member and the receiving surface, it is possible to open the door normally used for opening and closing to the outside when the door is locked. To prevent the upper and lower parts of a connecting stile of an opening/closing door from deflecting toward the outdoor side even when a large force is applied.

First Embodiment In this embodiment, the present invention is applied to the above-mentioned double door device, and the same parts as in the conventional device are given the same numbers. An airtight material holding piece 17 is provided over almost the entire length of the lock side stile 4 of the child door 3 as a fixed door member, which faces the tip (lock side stile 6) of the main door 2 which is normally used as an opening/closing door. Two receiving portions 18 are fixedly provided above this airtight material holding piece 17 and on the side surfaces of the upper and lower parts of the room near the lower frames 11 and 12. The receiving portion 18 has a cylindrical hole 19 formed in the left-right direction, and a receiving surface 20 is formed by a curved portion of the cylindrical hole 19 facing toward the indoor side. This upper and lower receiving part 1
Bases 21 are disposed at the upper and lower parts of the lock side stile 6 of the main door 2, respectively, facing the lock side stile 8, and a slide bar 22 shown as an engaging member is attached to the base 21 so as to be slidable and rotatable in the left and right direction, Further, a handle 23 is attached to the slide bar 22 so that the slide bar 22 is slid in the axial direction by the handle 23, and its tip is engaged with and disengaged from the cylindrical hole 19. Moreover, 24, 24 are engagement holes in which the handle 23 is engaged and the slide bar 22 is positioned.

When locking the door, engage the locking device 7 and move the vertical slide bar 22 to the right to close the cylindrical hole 1.
9. In this case, for example, when the wind pressure from outside is positive, the main door 2 is only pressed against the door frame 1 as in the conventional case, and the upper and lower parts of the connecting frame 6 do not bend. Also, when pressure is applied to open the main door 2 to the outside, the upper and lower ends of the stile 6 try to bend to the outside using the locking device 7 as a fulcrum, but the slide bar 22,
22 is pressed against the receiving surfaces 20, 20. Receiving surface 20,2
0 is located at the upper and lower portions of the stile 6 which are closer to the upper and lower frames 11 and 12, which are more difficult to bend than the middle part of the stile 6 due to the locking of the French drop 5 and the upper and lower frames 11 and 12. The force toward the outdoor side can be reliably received, and the upper and lower ends of the joining frame 6 can be surely prevented from bending toward the outdoor side.

Second Embodiment Figures 4 and 5 show another embodiment applied to a double door device, in which a rectangular engagement hole 119 that opens toward the main door 2 is provided in the joining stile 4 of the child door 3. Receiving part 11
8 is fixedly installed, and the indoor side surface of this engagement hole 119 constitutes a receiving surface 120. On the other hand, an engagement bar 122 is integrally connected to the tip of an operating pin 123 in the connecting frame 6 of the main door 2, and is rotatably supported by a base 121, so that the operating pin 123 can be rotated from the indoor side. The engagement bar 122 can be engaged with and disengaged from the receiving surface 120 by moving the engagement bar 122 . According to this embodiment, most of the device is hidden within the stile, and the exterior appearance of the door is less affected.

Third Embodiment Figures 6 and 7 are examples of application to a single door device.
An airtight material holding piece 217 is protruded from a vertical frame 214 serving as a fixed door member that faces the tip (lock side stile 206) of the opening/closing door 202 over almost the entire length of the top and bottom. On the side of the room,
Receptacles 218, 218 are fixedly provided at the lower part, respectively.
This receiving portion 218 includes a receiving surface 220 facing toward the indoor side, and also includes a receiving piece 219 protruding from this receiving surface 220 toward the indoor side. On the other hand, the opening/closing door 202
A conventional locking device (not shown) is attached to the lock side stile 206 at the middle part in the vertical direction, and a base 221 is fixed facing the receiving part 218, and an engagement bar 222 is fixed to the base 221. is rotatably supported, and its tip engages and disengages from the receiving surface 220.

In the above three embodiments, the receiving portion is provided on the fixed door member, and the engaging member is provided on the opening/closing door, but they may be attached in the completely opposite manner.

Effects of the Invention As described above, in the present invention, in an opening/closing door device having a locking device at one location between the top and bottom of a lock side stile, when this opening/closing door is in a closed state, a fixed door member facing this opening/closing door is opened/closed. We made it possible to connect the upper and lower parts of the door lock side stile close to the upper and lower frames, so
By connecting them in this way, when a force such as negative pressure from outside is applied to open the door during a typhoon, the upper and lower parts of the lock side stile of the door will
It is close to the connecting part with the lower frame and locks with the upper and lower parts of the fixed door member, which is difficult to bend, and can reliably receive large forces such as negative pressure, preventing the upper and lower parts of the lock side stile of the opening/closing door from bending outside. This has the advantage that there is no gap between the door frame and the top and bottom of the opening/closing door, preventing rain and wind from entering. In addition, the receiving part is provided within one of the lock side stile of the opening/closing door and the fixed door member, or on the indoor side of that member, and the other member is provided with an engaging member that engages and disengages from the receiving surface of the receiving part from the indoor side. Therefore, even if the locking device is removed from outside, no one can gain access from outside, which is advantageous in terms of crime prevention.
