Description

{Apparatus For Emergency Escape For Building}

The present invention relates to a disaster prevention facility, and more particularly, to an emergency escape apparatus capable of helping a quick escape from a high-rise building in the event of a fire.

The main cause of deaths in buildings is fire due to toxic gas. Therefore, if the structure of the firefighting personnel is delayed, it is urgent to escape from the building promptly while protecting the respiratory system. For this reason, according to the Fire Service Act, an emergency escape device or a stiffener should be provided in a certain building. Conventionally, emergency escape apparatuses of various forms or systems have been proposed. Emergency escape devices should be considered for users who are in an uneasy state of mind and body, and it is desirable to allow many people to evacuate safely and quickly. The conventional emergency escape apparatus is as follows.

Korean Patent Application No. 10-2013-0073699 discloses a fire extinguisher having a guide portion vertically installed on an underside of an escape cap installed in a escape hole of a floor escape space of a building, A lower portion lowered along the guide portion when the large pizza is loaded, a tough portion lowering the lower portion along the guide portion at a constant speed, a return portion returning the lower portion lowered along the guide portion to the original position, A locking portion formed at one side of the descending portion and the guide portion to maintain the depression portion positioned above the guide portion and a friction portion provided at the descending portion to provide a frictional force between the descending portion and the guide portion when the hardening function of the hardened portion is lost And an emergency control section for enabling a stable descent of the descending section. According to this, the descending portion has an area that is longer than 1.5 times in the longitudinal direction so that a plurality of persons can be carried, and the emergency escape portion including the guide portion, the stiffness portion, the return portion, and the emergency control portion on both sides in the longitudinal direction of the descending portion, Device is provided.

In addition, Korean Patent Application No. 10-2011-0012870 discloses an escape cap which is installed in an escape hole of a floor escape space of a building, a guide member vertically installed on the lower side of the escape port cap, A descent member descending along the guide member when the large pizza is loaded, an intensifying member for descending the descending member at a constant speed along the guide member, a return member for returning the descending member lowered along the guide member to the original position, And a locking member for maintaining the lowering member in a state of being positioned above the guide member, wherein the returning member is configured to lower the lowering member in a winding operation and lower the lowering force in a releasing operation And a spring for transmitting the spring to the stiffening member connected to the member so that the descending member is lifted.

As can be seen, the conventional emergency escape apparatus generally includes a means for descending at a constant speed by means of an elevator, and a descending portion (or descending member). However, the descent part should be returned to the original state for the next user. This is because an emergency escape device can not be provided depending on the number of users of each user.

Because of this situation, it takes too much time for many people to escape. So, you may get an accident while escaping. There is also a problem in that rainwater may be impregnated when stored without being used for a long period of time, or a possibility that a fault may occur due to sunlight or temperature change.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings attached hereto. First, one embodiment will be described with reference to Figs. 1 to 3 and Fig. Other drawings are to be quoted where necessary.

The emergency escape apparatus for a building according to the present invention has a size and a shape of an entrance. The evacuee does not have to try to escape from the uneasy attitude through the narrow window. The emergency escape apparatus for a building according to the present invention (hereinafter referred to simply as an escape apparatus) can be provided without protruding outside the building as shown in Figs. 1 and 7. The outer surface can be made of material and color similar to the exterior of the building, so that it can not be seen clearly from the outside. Hereinafter, the detailed configuration will be described.

A door frame having an entrance size is fixed to an entrance of a building of the building (B). The door frame 10 includes a pair of horizontal bars 11 and 12 and a pair of vertical bars 13 and 14 and has an elongated rectangular shape in the vertical direction. It is very similar to the door frame in general doors, but it should be installed firmly so as not to be detached from the entrance due to external force. For this purpose, the door frame 10 may be provided with anchor means fixed to the building wall.

The door 10 is provided with an outward opening / closing door 20 which is opened in a hinged manner toward the outside as indicated by an arrow. According to the embodiment of the present invention, the outward opening / closing door 20 can include two upper opening / closing doors 21 and 22 and one lower opening / closing door 23.

The upper opening and closing doors 21 and 22 may be hinged doors that are opened while rotating about a vertical axis by hinges provided on both side vertical bars 11 and 12 of the door frame 10. [ The lower opening / closing door 23 may be a hinged door which is opened while rotating about a horizontal axis by a hinged portion provided in the lower side horizontal bar 12 or the vicinity thereof. On the inner surface of the outward opening / closing door, the handles 21a, 22a, and 23a can be opened or closed by hand (see FIG. 6).

According to the embodiment of the present invention, the lower opening and closing door 23 can have a rigidity that can be used as a footrest by two to four persons in a fully opened state. The inner surface of the lower opening / closing door 23 may be provided with a recessed portion for preventing slippage. The link mechanism allows the lower opening and closing door 23 to be opened only at a predetermined angle, preferably until it is horizontal as shown in Fig. The link mechanism is provided through a handrail 30 described later.

Since the lower opening and closing door 23 serves as a foot plate for spreading to the outside of the building, the escaping person standing on the lower opening and closing door 23 can reduce the suction of the smoke generated in the building and can escape to some extent from the heat caused by the fire. Such a configuration can contribute greatly to reducing human injury.

The railing 30 is installed over the door frame 10 or the outward opening / closing door 20 so as to spread out toward the outside of the building B. The handrail 30 is provided to prevent falling, and the transverse bars 32 and 37 provided at the chest height from the waist of the adult are connected in a " C "shape. Each handle 21a and 22a of the upper opening and closing doors 21 and 22 is formed to be bent at right angles in the upward direction so that the side transverse bar 32 of the handrail 30 is opened, (21a, 22a).
On the inner surface of the lower opening / closing door (23) of the outward opening / closing door, a rigidity holding bar (31) for reinforcing the rigidity is fixed in the lateral direction. The rigidity holding bar 31 may function as a handle. The transverse bars 32 and 37 are connected to the rigidity maintaining bar 31 by longitudinal connecting bars 33 and 34 on the left and right sides. They are all hinged and foldable.

As a result, the transverse bars 32 and 37, the connecting bars 33 and 34, and the lower opening and closing door 23 constitute a polygonal link mechanism in the form of a rhombus when viewed from the side. The lower opening and closing door 23 may be opened or closed by the link mechanism and the opening angle may be limited. As shown in FIG. 3, the connecting bars 33 and 34 are composed of the upper bars 33a and 34a and the lower bars 34a and 34b, respectively, by having folds that can be folded or unfolded like a joint. This is a mechanical consideration that allows the link mechanism including the outward opening / closing door 23 to be folded or opened smoothly. On the other hand, an intermediate connecting bar 35 for constituting a ladder having rigidity can be hingedly connected between the transverse bar 37 and the stiffness retaining bar 31. The intermediate connecting bar 35 also has a structure in which the upper bar 35a and the lower bar 35b are foldably connected.

On the other hand, a descending member is provided for allowing the escenter to ascend to the footstool, that is, the lower opening and closing door 23 and then ride down toward the ground. The descending member is fixed at one end to the railing (30) or the door frame (10) and the other end extends toward the ground outside the building (B). According to the present embodiment, the descending member may be the stem ladder 40. The descending member made of the ladder 40 can be stored in a state of being dried like a roll.

The string ladder 40 is composed of a pair of ropes 41 and a step 42 fixed at regular intervals along the extending direction of the rope. The length of the string ladder 40 will be determined by the height at which the escape apparatus is installed.

The descending member can take various forms. For example, a ladder that can be pulled out of a scope antenna can be possible, and it can be a single rope. Also, a net having a width that can be used by two or more persons at the same time may be used. This descending member is normally held in a folded state between the door frames 10.

According to this embodiment, the aforementioned ladder is also provided between the handrail and the lower opening / closing door. This ladder is rigid and is provided on an extension of the ladder 40. [ The escapee can easily move to the ladder by using the crossbar 36 of this ladder.

According to another embodiment of the present invention, the door frame 10 may further include an inwardly opening / closing door (not shown) opened toward the inside of the building. This is a linkage including the handrail 30 and a connection to it to ensure that the ladder wound like a roll is not visually exposed in the interior of the building. The manner of opening the inward opening / closing door can be variously selected. The inward opening / closing door may also be configured to open automatically upon a fire or to automatically release the locking device.

4 to 5 relate to a handrail 30 'and a link mechanism including the handrail 30' according to another embodiment of the present invention. According to this embodiment, the structure is somewhat simplified. The ladder is installed on the ledge (30 ') through the carabiner and extends toward the ground. Although not shown, the lower opening and closing door 23 and the railing 30 'are unfolded to the angle shown in Fig. 5 through the unfolding process of Fig. 4 by a predetermined lever mechanism. For example, a flexible tension wire such as a chain, a wire or a rope may be connected between the lower opening and closing door 23 and the door frame 10 to prevent the lower opening and closing door 23 from sagging downward.

A handle bar 38 may be provided on the handrail 30 'to connect the stem ladder 40 and hold it by hand when it is lowered. Reference numerals not previously described will refer to the previous embodiments.

According to another embodiment of the present invention, it is preferable that the outward opening and closing door 20 is normally locked by a locking device. There is a risk of a fall accident when opened incorrectly. And the outward opening / closing door 20 may have a configuration such that when a fire occurs, it is automatically opened or released by the signal of the fire detector. The fire alarm may be opened at the same time as the fire alarm is activated, or may be opened by turning on a switch provided near the entrance. This switch can have a shape and structure similar to a switch that rings a fire alarm.

According to another embodiment of the present invention, a ventilation window (or a smoking window) may be installed in the outward opening / closing door. In the normal case, it is possible to ventilate the room through the ventilation window. In the event of a fire, it can be used to discharge smoke.

According to another embodiment of the present invention, the outward opening / closing door is provided as a non-combustible material. And the upper door or the above-mentioned door may be closed again to completely or partially seal the doorway. In other words, it is intended to provide an effect of being maximally deviated from the smoke or flame generated in the building by closing the upper opening door and the inward opening door when the escapee climbs on the lower opening and closing door functioning as a footing function.

The above description is only an example based on the technical idea of the present invention. Those skilled in the art will recognize that various modifications may be made by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims. For example, all embodiments described above may be freely combined and practiced by those skilled in the art, and any combination thereof should be construed as being included within the scope of the present invention.
