Description

  The present invention relates to a wheelchair for a handicapped person when a fire is generated in an indoor passage of a building, and when the evacuation door is opened in a sleeve door provided with an evacuation door on the side of a shutter partitioning the space. The present invention relates to a shutter sleeve door device with an evacuation door for a wheelchair that can easily pass through without obstacles.

  In general, a sleeve door provided in this type of shutter opening / closing device includes, for example, an escape door on a part of the sleeve door. However, the evacuation door is generally implemented such that the sleeve door is provided with an opening of the size of the door so that the door can be opened and closed for evacuation.

As described above, the sleeve door with the conventional evacuation door has the evacuation door installed in the frame of the opening portion where the outer periphery of the sleeve door is a frame. There was a problem that the wheelchair of the handicapped could not pass because the lower frame was located.
The present invention is an improvement of these conventional sleeve doors, the bottom frame of the opening for attaching the escape door of the sleeve door is removed, the passage is formed flat, and the escape door is opened. At the same time, wheelchairs can freely pass and evacuate. Further, the present invention provides a shutter sleeve door device with a evacuation door for a wheelchair, in which a smoke-proof and fire-proof smoke barrier seals are respectively installed at a joint portion and a lower end of the sleeve door and the evacuation door.

In the present invention, in order to achieve the above object, an opening for installing an evacuation door is formed in the sleeve door. The opening is formed in a lacking state in which a lower frame is not provided at the lower end. The escape door is pivotally attached to a predetermined position of the sleeve door by an upper hinge and a lower hinge so as to be freely opened and closed.
In addition, a smoke-proof and fire-proof hermetic seal made of synthetic rubber or the like is installed at the summing portion where the sleeve door and the evacuation door are joined. Furthermore, various smoke barrier seals are attached to the lower ends of the sleeve door and the evacuation door.

  As described above, according to the shutter sleeve door device with a evacuation door for a wheelchair, as in the past, the effect of solving the disadvantage that the frame of the sleeve door is located under the evacuation door and the wheel of the wheelchair is obstructed and cannot be passed. In the event of a fire, people with disabilities can safely and easily escape from the evacuation door by operating their own wheelchairs. In addition, a smoke-proof and fire-proof smoke-proof seal is also installed at the summit of the sleeve door and the evacuation door and at the lower end of the sleeve door and the evacuation door. There is an effect to have a good smoke barrier.

  It is the front view which a part of sleeve door with a refuge door of the present invention removed.   It is the top view which similarly showed the crossing of FIG. 1 of this invention.   It is the cross-sectional top view which showed the summoning part of the closed state of the evacuation door and sleeve door of this invention.   It is the slope figure which showed a part of lower end of the sleeve door of this invention.

  In the present invention, the sleeve door with the evacuation door is rotated and closed by the operation of the sleeve door (1) with the occurrence of a fire, and the shutter (3) lowers the guide rail (7) of the sleeve door (1) by its own weight. And close it all. At this time, the evacuation door (2) can be evacuated by driving by itself without any help from the handicapped person's wheelchair as well as the refugee and the fire extinguisher by the free opening / closing operation.

The embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a front view of a closed state in which an escape door (2) serving as an entrance is installed on a sleeve door (1), and reference numeral (3) denotes A shutter is shown, and the sleeve door (1) is positioned in the sleeve door storage frame (5) of the side wall (4), and is formed in a vertically long dimension up to the height of the lintel. The sleeve door (1) is installed on one or both sides of the shutter (3).
The sleeve door (1) is not formed with a lower frame at the lower end of the opening for installing the evacuation door (2), and the upper and lower hinges (6) in the sleeve door storage frame (5) of the side wall (4). ) (6) is pivotally mounted so as to be openable and closable, and a guide rail (7) for raising and lowering the shutter (3) is formed at the open end of the sleeve door (1). The sleeve door (1) is provided with a limit switch (8) that operates in conjunction with opening and closing at the top, and is fixed by an upper lock (9) for stopping and a lower lock (10) at the bottom. The storage case (15) is provided with a winding shaft (16), an automatic shutter closing device that operates in conjunction with the limit switch (8), a switch for releasing the brake, and the like.

Next, the evacuation door (2) is pivotably attached to the upper and lower ends by an upper hinge closer (11) and a lower hinge closer (12).
Further, as shown in FIGS. 3 and 4, the joint surface between the escape door (2) and the opening of the sleeve door (1) is made of synthetic rubber or the like and has an airtight seal (14) (14). It is in contact. Further, a smoke-proof and fire-proof smoke-shielding seal (13) is attached to the lower end surface of the sleeve door (1) and the lower end surface of the evacuation door (2) so as to be completely sealed.
