Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a basement emergency escape exit that is installed above ground to serve as a backup when the basement entrance used for emergency evacuation is broken and becomes unusable. This relates to a door device.

(Problem to be solved by the invention) In underground rooms used for emergency evacuation such as shelters, when the regular entrance of the club room is destroyed by a blast or sand and becomes unusable, A backup emergency exit leading to the area must be provided.

However, other escape exits may become unusable due to being buried by the explosion wind, flying sand, and other falling objects, so the above-ground escape exit should be configured so that it does not easily become clogged, and that those who expose themselves are inside. The problem is that the door must be placed so that it can be opened and closed from the outside. The present invention seeks to solve this problem.

(Means for Solving the Problems) The present invention aims to solve the problems mentioned in the previous section. It consists of a sloping roof-type hood with a diagonal angle, and a slanted lid whose lower end is pivotally supported and whose upper end is pressed into contact with the hood in a palm-shaped manner.The slanted lid is pivotally supported inside the wall of the emergency escape hole, and its axis The handle is below the support part, and the handle is above the pivot part in contact with the inner surface of the tilted lid.
''-shaped lever, with the handle protruding diagonally downward into the inside of the emergency escape hole, and at the same time when the handle is pushed until it almost touches the wall, the portion of the ``<''-shaped lever that contacts the inner surface of the slanted lid is moved along an arcuate trajectory. The device is characterized by a structure in which the escape port is opened by sliding it downward and pushing the inclined cover from the inside.

(Example) A preferred embodiment of the present invention will be described with reference to the accompanying drawings.

In the figure, 1 is a basement constructed with concrete as a shelter, and is equipped with an entrance staircase 2, an entrance door 3 with extremely thick walls and filled with concrete, and an interior 4 surrounded by concrete, etc. A nearly vertical emergency escape hole 5 surrounded by a wall is provided.

This hall 5 has a long wall extending from the interior 4 and a hall 5!7.8 rising from the ceiling of the interior on all four sides, and an almost perpendicular staircase 9 is attached to the extension wall 6. . Although not shown in the drawings, this can be achieved by providing a shutoff door on the ceiling of the indoor interior 4 that can open and close the emergency escape hole 5.

At the ground level of the emergency escape hall 5, an extension wall 6 and a hall wall 7.8 are provided to protrude slightly from the ground, the hall wall 7.8 is further extended, and the upper part of the hall wall 7 shown in the drawing is a hood with a slanted roof 10. form 9.

The slanted roof type 10 covers most of the internal cross-sectional area of the emergency escape hole 5, and opens an escape exit 11 on the ground depending on the shape of the hood 9.

Reference numeral 12 denotes a hinge 14 attached to the inner surface of the above-ground protrusion of the extension wall 6.
It is an opening/closing door with the lower end attached to the hood 9, and the h1 is inclined in the shape of palms together as shown in Fig. 1.2 with respect to the hood 9.
A drainer 15 is provided at the upper edge to cover the hood 9, and the inner surface 13 is finished at a smooth oblique angle.

Emergency escape hall 5! On the hole wall 7 facing the long wall 6, a "<"-shaped lever 18 supported by a pongee 17 is pivotally supported, as shown in an enlarged view in FIG. The "<" shaped lever 18 is! As shown in Fig. #3, a handle 19 is located below the shaft 17, and a roll 20 for horizontal force is fitted to the upper end above the shaft 17, and the handle 19 is diagonally shaped for emergency escape. Protruding into the interior of Hall 5,
The projecting angle of the 1 ton wheel 19 is determined by the roll 2° coming into contact with the upper part of the inner surface 13 of the opening/closing door 12. 1
Reference numeral 6 denotes a ventilation hole provided in the slanted roof 10 with the outer end slanting downward.

In the present invention, when a person ascends the emergency escape hole 5 and presses the handle 19 until it comes to rest against the hole wall 7,
The "<"-shaped lever 18 rotates around the shaft 17, and its upper end slides on the inner surface 13 of the opening/closing section 12 in an arc-shaped trajectory.

As a result, the opening/closing door 12 is pushed and falls down as shown by the chain line in FIG.
open.

The escapee manually removes the upper part of the shaft 17 of the "<"-shaped lever 12 which is placed over the upper part of the emergency escape hole 5, or passes through the side and exits from the escape port 11.

(Operations and Effects of the Present Invention) As described above, the above-ground part of the basement emergency escape exit of the present invention is opened and closed by pressing the handle 19 located below the pivot portion of the "<"-shaped lever 18 and using the upper end of the lever 18. In addition to having a simple structure that opens the escape exit 11 on the ground by pushing the door 12, the slanted roof 10 of the hood 9 and the opening/closing door 12 are shaped like palms together, so that dirt and other fallen objects blown away by the blast wave can be removed. It is possible to prevent as much as possible the damage that the escape exit 11 and opening/closing port 12 on the ground are buried by sliding on the upper surface. Further, damage caused by falling objects falling into the indoor interior 4 of the basement can be prevented.

Furthermore, even if an external force is applied to the above-mentioned palm-shaped hood 9 and opening/closing door 12 from a horizontal direction, the external force is repelled by the inclined surface as shown by the repulsion arrow #Ia in FIG. This has various effects such as preventing loss of function of the above-ground part of the emergency escape hall 5 as much as possible.
