Abstract

The present invention relates to an evacuation device in case of a disaster in a building, which helps people safely escape from flames or toxic gases. The evacuation device allows a bottom rotating part of a balcony to be rotated downward and opened by a user's load when a lock is released with the user being positioned on a support plate on the bottom surface of the balcony, and a ring-shaped leaf spring to be compressed and a wire to be released from a roller at the same time when a hydraulic cylinder is released by the load of the person positioned on the support plate. The support plate is moved down to a lower floor by the wire, wherein a winding and unwinding length of the wire is controlled by a gear ratio between a gear on which a cylinder wire of the hydraulic cylinder is wound and a gear on which the wire is wound. Then, the support plate is restored to the original position by a restoring force of the ring-shaped leaf spring and the hydraulic cylinder after the person steps down from the support plate, so the next person can continue to use the evacuation device.

Description

Evacuation device in case of disaster in building {omitted}

The present invention relates to an evacuation device in the event of a disaster in a building, and more particularly, when the lock is released while the user is positioned on the pedestal on the bottom of the balcony, the bottom rotating part of the balcony rotates downward by the user's own load and opens, The hydraulic cylinder is released by the load of the person located on the pedestal, and the ring-shaped leaf spring is compressed while the wire is unwound while being wound on the roller. It relates to an evacuation device in case of a disaster in a building so that the pedestal can be moved to its original position by the return force of the cylinder and ring-type leaf spring and the next person can continue to use it so that it can be safely evacuated from flames or toxic gas in case of a disaster. .

In general, a veranda of an apartment house is a living space that is used as a place to view the outside and install a drying rack to grow flowers or dry clothes.

There is a handrail installed in the veranda, and the handrail functions to prevent accidents such as falling from the building by preventing the occupants from going out of the veranda when the window is opened.

In addition, a lightweight partition (boundary wall) is installed on one wall of the veranda that can be destroyed and moved to the next door in case of a fire. Therefore, in case of emergency such as fire, it cannot be used for its original purpose in many cases.

Accordingly, in the event of a fire in a building or apartment house, the evacuation of evacuees temporarily evacuated to the veranda is delayed and life-threatening.

In the prior art, fire evacuation devices such as a top-down evacuation exit that can be installed on a balcony in preparation for the occurrence of a fire in a building structure, such as an evacuation device, have been developed.

These fire evacuation devices are sometimes used as a means of transport for intruders, they are vulnerable to the risk of falling, and various household items are placed on the balcony where the fire evacuation device is installed. There is a problem that it does not work.

[Prior Art Document 1] discloses an evacuation structure that can secure a space for the rescued person to temporarily wait on the outer wall of the building.

This evacuation structure is

An external frame provided to be rotatable at a predetermined angle so that a person to be rescued can wait in the open part of the outer wall of the building;

It is provided inside the outer frame and includes a footrest provided with a support for supporting a load.

As another example, [Prior Art Document 2] discloses a fire evacuation facility installed on a balcony, etc. in a foldable manner.

This fire evacuation and evacuation facility was developed so that evacuees can evacuate from flames and poisonous gas furnaces and wait for rescue while staying inside the evacuation facility by securing an evacuation space by spreading the panel walls to the outside of the building in case of a fire.

As another example, [Prior Art Document 3] discloses an emergency escape facility in which the handrail is deployed in an emergency to provide an evacuation space and at the same time escape out of the building through a ladder.

However, in the case of [Prior Art Document 1] and [Prior Art Document 2], in case of an emergency such as a fire, an evacuator must stay at the fire location and wait for rescue, so a safe evacuation site is selected due to the limitation that cannot be completely escaped from the fire risk. There is a downside to not being able to provide it.

In addition, [Prior Art Document 3] has the advantage of being able to evacuate to the ground in case of fire, but when evacuating vertically to the lower floor, the evacuation passage formed at the bottom of the evacuation facility is always open, so there is a risk of falling when evacuating from a high floor. There was the problem of coexistence.

Thus, on November 20, 2018, registered patent No. 10-1922174 (deployment type fire evacuation device) was proposed,

This includes a side fence unit having a pair of ladder blocks that are rotatably installed on the railing of the building structure,

A front fence portion having a plate-shaped block rotatably installed in the side fence portion and having a plurality of through holes formed therein;

a gate block body composed of a footrest unit having a pair of stepping plates rotatably installed at the lower end of the front fence unit;

a fixed post fixedly coupled to the railing;

A support frame that can be moved down using a connector inserted into the fixed post;

A pair of side fence portions rotatably coupled to both sides of the support frame;

A plate-shaped plate block coupled to the pair of side fences and disposed on the front side;

a transport block body comprising a footrest having a pair of stepping plates hinged to the support frame and the plate-shaped block, respectively;

Auxiliary connector for connecting between the fixed post and the plate-shaped block; including,

When unlocking by releasing the lock line connected to the pillar, the gate block body is deployed forward to form an evacuation space, and the transport block body is separated from the gate block body and arranged side by side when unlocking the lock line connected to the pillar is deployed forward to form an evacuation space and to move downward in the vertical direction from the fixed post,

The auxiliary coupler is rotatably coupled to each other using ball bearings installed on both fixed shafts, or the auxiliary coupler is configured to rotate by inserting hooks on both fixed shafts.

However, according to the conventional deployable fire evacuation device as described above, when the lock is released by releasing the lock line, the gate block body is deployed forward to the evacuation space formed so that the transport block body descends from the fixed post in the vertical direction to cause a fire on the upper floor. Although it was possible to safely evacuate when there was a problem, there was a problem that other people on the same floor could not evacuate because there was no function to return to the original state after one person moved down.

Accordingly, the present invention is to solve the conventional problems as described above, and when the user releases the lock while the user is positioned on the pedestal on the bottom of the balcony, the rotating part of the bottom of the balcony rotates downwardly and opens by the user's own load, The hydraulic cylinder is released by the load of the person located on the pedestal, and the ring-shaped leaf spring is compressed while the wire is unwound while being wound on the roller. The purpose of this is to provide an evacuation device in case of a disaster in a building so that the pedestal can be moved to its original position by the return force of the cylinder and ring-type leaf spring and the next person can continue to use it so that they can safely evacuate when a disaster occurs.

The evacuation device in case of a disaster in the building of the present invention for achieving the above object,

When the lock is released while the user is positioned on the pedestal on the bottom of the balcony, the rotating part of the bottom of the balcony in contact with the pedestal can be rotated around the hinge by the user's own load,

The hydraulic cylinder is released by the self-load of the person located on the pedestal, and at the same time compresses the ring-type leaf spring wound around the shaft of the gearbox so that the wire is unwound while being wound on the roller.

As the pedestal moves downward, the bottom rotating part of the balcony is opened while rotating downward around the hinge, so that the pedestal where the person is located in the space moves to the lower floor,

The pedestal moves downwards to the lower floor by the wire whose length is unwound and wound by the gear ratio between the gear rotated by the saline wire of the hydraulic cylinder and the gear on which the wire is wound,

After the pedestal is reached and a person gets off the pedestal, the pedestal moves to its original position by the restoring force of the hydraulic cylinder and the ring-type leaf spring so that the next person can continue to use it. It is characterized in that it is configured to do so.

In the event of a disaster in the building according to the present invention, the evacuation device releases the locking device while the user is positioned on the pedestal on the bottom of the balcony so that the bottom rotating part of the balcony is rotated downwardly and opened by the user's own load,

The hydraulic cylinder is released by the load of a person located on the pedestal, and at the same time compressing the ring-shaped leaf spring while the wire is unwound while being wound around the roller,

The pedestal moves down to the lower floor by the wire whose length is controlled after being unwound by the gear ratio between the gear rotated by the cylinder wire of the hydraulic cylinder and the gear on which the wire is wound. By the return force of the leaf spring, the pedestal moves to its original position so that the next person can continue to use it, which has the effect of safely evacuating from flames or toxic gases when a disaster occurs.
