Description

[Correction under Rule 26 04.05.2017] Handrail with evacuation function

The present invention relates to a handrail having an evacuation function that is simple in structure, beautiful in appearance, and has no trouble of trouble and malfunction, so that it can be easily operated at the time of evacuation to secure an evacuation space and safely descend downstairs.

In general, a balcony is a space configured for the purpose of space utilization and aesthetics of a high-rise building such as an apartment.

These balconies are equipped with railings using pipes to prevent safety accidents such as falling people or objects.

On the other hand, apartments do not have a separate emergency escape means due to fire law, so if an emergency such as a fire occurs, use an entrance or a balcony, but only use special personnel and equipment such as an elevated ladder to use the balcony. Emergency escape was possible.

Therefore, a technique that can be used by converting into an emergency ladder in an emergency such as a fire by using a handrail provided in a balcony of an apartment has been disclosed in Patent Documents 0001 to 0010.

In the case of Patent Documents 0001 to 0010, that is, in the related art, both ends of the railing frame composed of a plurality of vertical frames connecting the upper and lower horizontal frames and the upper and lower horizontal frames are connected to the balcony wall by a detachable joint, and the lower part of the one side is connected to the rotating shaft. After the joint was separated, the railing frame was separated from the balcony wall and rotated downward by using the rotating shaft on one side to be used as an emergency ladder to evacuate to the balcony below.

However, the emergency ladder has a problem that it is very inconvenient to work by lifting the ladder as a whole, the handrail frame is a heavy weight, the joint separated state.

Thus, as a countermeasure for improving the above-described problems in the prior art, a method using a driving means for automatically operating the rotation operation of the handrail frame through power supply has been disclosed. Since the wire is disconnected or the cover of the wire melts so that a short circuit occurs frequently, the power supply is not smoothly performed, and thus there is a problem in that the emergency function cannot be performed.

The plate portion 101 may be elastically supported such that the front and rear movement shaft 102 may move back and forth together with the plate portion 101 in a horizontally prepared state.

Next, the scaffolding part 310 and the auxiliary scaffolding part 350 are prevented from being exposed in the front side outward direction of the handrail frame part 40 and the front side outward direction of the fall prevention frame part 50, respectively. In order to make the appearance of the handrail frame portion 40 and the appearance of the fall prevention frame portion 50 more beautiful, as shown in FIGS. 2 and 3, the lower front side and the fall of the handrail frame portion 40. The front side of the prevention frame portion 50 may be fixed in a variety of ways, such as

bolts

200, 300 covering the scaffolding 310 and the auxiliary scaffolding 350, respectively.

In addition, in order to prevent the other handrail 320 from being exposed to the front side outward direction of the handrail frame 40, the other handrail 320 is located at the front side of the accommodation space 430 to cover the other handrail 320. The plate 400 may be fixed in various ways such as bolt fixing on the other front upper part of the handrail frame part 40.

In order to prevent noise generated while the

plates

200, 300, and 400 are shaken by strong winds, the

plates

200, 300 have a plurality of through

holes

201, 301, and 401 through which strong winds may pass. Each may be formed at regular intervals.

The present invention configured as described above has the advantage that the structure is simple and beautiful in appearance, there is no fear of trouble and malfunctions, so that it can be easily operated at the time of evacuation to secure an evacuation space and safely descend to the lower floor.
