Detailed Description of the Invention The present invention provides an escape device installed inside a building, especially when an emergency situation such as a fire occurs on the upper or lower floor. Regarding the escape device used when evacuating, an evacuation route is formed that connects the floors of the upper and lower floors by the footrest provided on the frame and the auxiliary cylinder, and the tread of the evacuation device attached to the lower inner wall of the auxiliary cylinder. To provide an escape device that allows a person to evacuate quickly and safely by smoothly transferring from an evacuation device to a foothold or from a foothold to an evacuation device without feeling discomfort. It is.

The structure of the present invention will be explained in detail with reference to the embodiments shown in the attached drawings. 1 is a floor slab 2 that partitions the ground floor and underground floor of a building.
A frame 3 is fitted into the hole 1, and a holding part 4 is provided at the open end on the floor side to maintain the open state. A cover plate 5 is provided rotatably around a rotating shaft.

An auxiliary cylindrical body 7 made of noncombustible material such as iron or stainless steel is arranged between the lower end of the floor slab 2 and a ceiling plate 6 that is stretched at an appropriate distance from the floor slab 2. The upper end of the auxiliary cylinder 7 is joined to the lower surface of the hole 1, that is, the lower surface of the floor slab 2 around the periphery of the hole 1, and the lower end is joined to the ceiling plate 6 for installation.

At the lower inner wall of the auxiliary cylinder 7, the upper end of the evacuation device 10, in which a plurality of sliding rods 9 each having a step board 8 protruding from the lower end, are slidably connected to each other, that is, the uppermost sliding rod 9 The upper end is attached via a bracket 11, and when not in use, each sliding rod 9 is stacked together and stored inside the lower end of the auxiliary cylinder 7, and when in use, each sliding rod 9 is connected to the It is designed to extend toward the floor of the floor.

In addition to the above-mentioned evacuation equipment, rope ladders and steel ladders may also be used.

A plurality of footrests 12 formed in a substantially U-shape are provided on the inner walls of the frame body 3 and the auxiliary cylinder body 7 located directly above the evacuation device 10.
The base side of the evacuation device 10 is fixed at an appropriate interval, and the step board 8 of the evacuation device 10 is made to protrude left and right from the sliding rod 9 so as to be located directly below the step portion 13 of the footrest 12.

When the evacuation device 10 extends downward, the plurality of treads 8 of the evacuation device 10 and the tread portions 13 of the plurality of treads 8 provided on the frame 3 and the auxiliary cylinder 7 cover the floor surfaces of the upper and lower floors. Evacuation routes are now being formed.

Reference numeral 14 denotes an opening/closing cable which has a grip part 15 at one end and a locking protrusion 16 at the other end, and this opening/closing cable 14 is guided by a pulley 1T provided on the back side of the ceiling plate 6 while being guided by the lower end force of the auxiliary cylinder 7. The locking protrusion 16 is removably fitted into a locking piece 19 of the cover plate 18 provided on the opening side of the ceiling surface of the auxiliary cylindrical body 7, so that the cover plate 18 is closed. The state is maintained.

To evacuate using the escape device configured as described above, first, when an emergency situation such as a fire occurs on the lower floor, the evacuee on the lower floor pulls the opening/closing cable 14 downward, and the tip The locking protrusion 16 is released from the locking piece 19, the cover plate 18 is opened, and the evacuation device 10 extends to the floor, and the footboard 8 of the evacuation device 10 and the treads of the plurality of footrests 12 are removed. 13 and
Evacuation routes are formed that are arranged vertically in a straight line and connect the floor surface of the upper floor and the floor surface of the lower floor.

The evacuee should follow this evacuation route, that is, the footboard 8 of the evacuation equipment 10.
and from the lower floor to the upper floor by passing through the auxiliary cylinder 7 and the footrest 13 of the foothold 12 of the frame 3. In the event of a fire or other emergency situation occurring on the upper floor, evacuees on the upper floor When the lid plate 5 is opened and the opening/closing cable 14 formed on the auxiliary cylinder body 7 is pulled upward, the locking protrusion 16 at the tip of the opening/closing cable 14 is released from the locking piece 9, and the lid is closed. As the plate 18 opens, the evacuation device 10 extends to the floor, and the footboard 8 of this evacuation device 10
and the tread portions 13 of the plurality of footrests 12 form an evacuation route that lines up in a straight line in the vertical direction and connects the floor surface of the upper floor and the floor surface of the lower floor.

The evacuees evacuate to the lower floor along this evacuation route, but first the evacuees sink their bodies into the hole 1 through the opening on the floor side and move to the foothold 12, but at that time, the surrounding area is flooded. Even if you are an evacuee, you can firmly support your body with the fixed foothold 12, and it is safe and does not cause fear.

Furthermore, the person moves from this foothold 12 to the evacuation device 10 and evacuates to the lower floor, but even when changing from this foothold 12 to the evacuation device 10, the hand firmly grasps and supports the fixed foothold 12. This eliminates the psychological fear of being at high places.

As described above, according to the present invention, a substantially U-shaped footrest is provided on the inner wall of the frame,
A plurality of roughly U-shaped footrests are fixed to the inner wall of the auxiliary cylinder, so when evacuees rush through the opening on the floor side and sink their bodies into the hole and move to the footholds, they are able to avoid contact with surrounding evacuees. It is safe because the fixed footrest can firmly support your body even if you are thrown.

Since the footrest can be used until most of the body is submerged in the hole, it is much safer than a conventional device with a handle provided only on the frame, making it ideal as an evacuation device.

When evacuating from an opening on the floor side using footrests and evacuation equipment, if you are in a high position near the floor side, you can use the fixed footrests to support your body with your hands and feet.
Even when your feet move onto the evacuation device, your hands can firmly grasp and support the fixed footrests, making it easier to use in high places compared to conventional devices that have handles only on the frame. You can safely evacuate without creating psychological fear of being in a certain position.

In addition, a retractable evacuation device having a plurality of treads is installed so as to be located directly below the footrest, and a passage connecting the floors of the upper and lower floors is created using the plurality of treads of this evacuation device and the plurality of footrests. Because of this, there is no difference in level between the footboard of the evacuation device and the plurality of footholds, especially when it is in use.
Since the evacuation route is almost on the same plane and connects the floors of the upper and lower floors in a straight line, evacuees can move from evacuation equipment to footrests, or from footrests to evacuation equipment without feeling any discomfort. , you can evacuate safely and quickly by grasping it smoothly with your hands or firmly placing your feet on it.

Furthermore, since the evacuation equipment is installed at the bottom of the auxiliary cylinder, relatively short evacuation equipment is required, and the auxiliary cylinder can be used for various floor heights and ceiling heights due to differences in height or ceiling height. Only the body needs to be adjusted, there is no need to manufacture frames of various sizes and evacuation equipment for each site, and they can be manufactured on an integrated production line.
The production line can be simplified, standard products can be used, the cost is low, and the delivery date can be shortened.

In addition, during construction, the frame, auxiliary cylindrical body, and evacuation equipment can be separated, making the work easier. Moreover, there is no need to complete construction of the building's floors and ceilings, and the work can be carried out separately. This can be done one after another as each part is completed, speeding up the installation as a whole, further shortening the installation time, and reducing construction costs.
