Description

[Detailed Description of the Invention] [Industrial field of application] The present invention consists of an integral fixed pillar that is always fixedly installed on the wall of the hatch part of the evacuation gate such as a corridor of a high-rise building, a general building, a veranda, etc. It is an evacuation ladder with the steps folded inside, and by operating the lever provided in case of emergency, the handles of the movable stanchions on both sides make it a ladder shape and open the hatch, it is safe to go downstairs or upstairs Evacuate, and after use, close the hatch, operate the lever to close the part, and use the handle on the column to hold the step inside the fixed column.
It relates to an evacuation ladder, more specifically to an evacuation ladder.

[Conventional technology]

Heretofore, as this type of evacuation ladder, it has been known that a suspension ladder made of wire rope or the like, installed on the outer wall of the window, or a ladder installed under the evacuation gate.

[Problems to be solved by the device]

Among those described in the prior art, the wire rope ladder is unstable because it swings, the installation of window creases is dangerous when moving to the ladder, and the ladder under the evacuation gate pushes the hatch due to invasion from the downstairs. Can be opened. Also, if a key is attached, there is a problem that the operation in an emergency becomes slow.

The present invention has been made in view of such problems of the conventional technology, and the purpose thereof is an emergency evacuation ladder, so that the step portion is always included in the fixed column, In the event of an emergency, by operating the lever and handle, a ladder can be formed safely and securely without impact, and it is intended to provide an evacuation ladder that is always a single strut that is unobtrusive and has an excellent appearance. .

[Means for Solving the Problems]

In order to achieve the above object, the evacuation ladder according to the present invention has a generally rectangular column-shaped fixed support column in which a substantially U-shaped cross section has a central portion pivoted widely with a pivot pin. It has a lockable part for opening and closing around the periphery, and it is a step in which movable struts are connected to both ends, and by operating the lever and handle part, it can be folded or opened and closed like a ladder. Along with the eggplant, it also opens and closes the hatch.

[Action]

The fixed column with the folding ladder is always fixed to the wall surface by the fixed body, and in the event of an emergency, it becomes a stable and stable evacuation ladder by operating the lever and the handle, which makes the evacuation agile and prevents accidents.

〔Example〕

 Examples will be described with reference to the drawings.

1 to 6, the fixed support column 1 has a width of approximately 9 cm,
It is formed in a tubular shape of a rectangular metal plate with a horizontal thickness of 5 cm. More specifically, a plurality of pivot pins 4 for steps, movable pins 6'and lever-leverages are provided in the central portion, and rolling portions 1'of step 2 and the locked portion 1 "for maintaining the horizontal position on both side surfaces. Multiple parts of the husband and wife are fixedly installed on the wall surface with fixed posts formed by sheet metal processing. In step 2, a slightly thick metal plate is formed with a wide center and wide narrow ends, and the cross section is roughly U-shaped. Pressed, pivot pin 4 is provided in the central portion, and opening 7 and closing 7'are provided in the periphery with some of the engaged portions of the husbands, and movable columns 3 and 3 connected to both ends. ′ Is approximately 5 cm wide,
Concave handle 10, concave engagement part of the stopper 9'of the hatch 9
12. Sheet metal working is applied to each part of the plurality of pivot pins 2 ', and the side surface of the fixed support column 1 is covered.

1 to 2 and 5, the lever 8 for opening and closing step 2 is a lever 8 in which the movable pin 6'and the bracket 6 are connected via the spring 5 from the pivot pin 4 It consists of a processed body.

The connecting rod 6 ″ in FIGS. 2 to 4 and 5 to 6 is provided with a plurality of pins 6 on a strip-shaped metal plate, is provided with an intermediate portion of the lever 8, and is connected to the movable pin 6 ′. By the action of the lever 8, it is engaged with or disengaged from the opening 7 portion of step 2, and also serves as a joint when adding.

In FIG. 4, the hatch 9 of the evacuation opening is always locked between the convex locking metal fitting 9 ′ between the concave locked portion 12 of the movable support column 3 and the fixed support column 1.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

The evacuation ladder according to claim 1 is a ladder in which a step is normally included in a fixed column in a foldable manner and can be opened and closed. Since the space for the fixed support is always available, the installation space is small, and therefore it is easy to install and use in a wide range, and the cost is low, and the appearance is excellent.

According to a second aspect of the present invention, the fixed pillar of the evacuation ladder is provided with a plurality of step portions, and is securely held by a horizontal locked portion, and is easily fixed to a wall surface or the like by a fixed body.

When the step of the evacuation ladder according to claim 3 is used, opening and closing is easy, and the foot is wide so that it is stable.

The movable pillar of the evacuation ladder according to claim 4 functions as a cover for the side surface of the fixed pillar when in a flat state, and is easy to grip when the ladder is used, and an accident is prevented by locking the hatch portion.

When the lever of the evacuation ladder according to the fifth aspect is used, it can be opened and closed easily and reliably and stably fixed by operating the lever with the movable pin interposed.

In the guide rod for the escape ladder according to the sixth aspect, the step is reliably stabilized by the plurality of pins of the band-shaped body. It also serves as an opening and closing part on the upper floors.
