Description

An emergency escape apparatus

The present invention relates to an emergency escape device, and more particularly, to a non-power emergency escape device capable of emergency emergency escape from the upper floor ceiling slab to the lower floor slab during a disaster.

Generally, buildings with a certain size or more are equipped with elevators to evacuate in the event of a disaster such as a fire or earthquake. The elevator is installed and operated on a window or a veranda, and if it is difficult to use stairs or elevators in the event of a disaster, the evacuator escapes to the outside through the elevator.

However, since evacuees have to escape while hanging on a slow-moving elevator rope, rapid evacuation is not easy, and accordingly, it is difficult to evacuate many people. In addition, in the case of the elderly, children, and women, there was a situation in which the use of the elevator was refused due to limitations in physical fitness or fear of heights, and in this case, rapid evacuation was not possible. For many of these reasons, a large number of disaster deaths and injuries have occurred.

In order to solve this problem, the need for an emergency escape device to form an escape hole in the ceiling forming the floor of the building and to escape to the bottom floor through the escape hole has emerged. Accordingly, recently, a pair of support pillars installed between the escape hole and the floor slab, a winch on which the wire is wound as being installed on the upper portion of the support pillar, and a mainspring that reversely rotates the winch after the winch is rotated and before being rotated. An emergency escape device has been developed, which consists of a foot and a scaffold that is removably coupled to a support column while connected to a wire. By such an emergency escape device, the evacuator can escape from the upper floor to the lower floor while riding on the scaffold, and then the mainspring part rotates the winch in the opposite direction to return the scaffold to the initial position so that other evacuators can escape. Did.

However, in the case of the emergency evacuation device, the footrests had to be durable for adults to board, so the weights were significant, and the size of the springs for returning these heavy footrests to the initial position was also inevitable. Therefore, the mainspring part prominently protrudes to the upper side of the emergency escape device, deteriorating the utilization of the surrounding space, and causing the evacuation of the evacuator to stumble during an emergency emergency escape process with water spoiling the exterior of the building.

In addition, the plate spring embedded in the mainspring portion is corroded over time and the return elastic force decreases. In this case, the springboard portion does not return smoothly to the initial position due to the decrease in the return elastic force, which delays the emergency escape. There was a problem that was connected to.

The present invention was created to solve the problems as described above, and by not using a clockwork, it is possible to realize the overall size compactly, and to provide a non-powered emergency ejection device that is easy to maintain by having a structure that does not fail. The purpose.

The rim housing 10, as shown in FIG. 2, has a rectangular shape as a whole, and is fixed to the emergency exit hole H of the ceiling slab S1.

Profile pillar 20, as shown in Figures 3 and 4, a pair of first and second edge fastening ends 23, 24 and a pillar body formed long along the front edge of the pillar body 21, (21) It includes a pillar hole 25 formed inside.

The first and second corner fastening ends 23 and 24 have a rod shape protruding toward the front side of the pillar body 21, and the emergency brake 100, which will be described later, is in close contact with the first and second brakes 103 and 104. As a result, a braking force for preventing the fall of the elevating skin 30 is generated.

The profile pillar 20 is manufactured by extruding a metal, for example, aluminum, and is used by cutting to a required length.

The elevating skin 30 includes first and second sliders 33 and 34 that are slidably coupled to the first and second edge fastening ends 23 and 24, and the first and second sliders 33 and 34. The slider support block 35 is coupled, the first and second support frames 36 and 37 fixed to the slider support block 35 and extending to the front side, and the first and second support frames 36 and 37 It is mounted on the support and includes a footrest 38 to which the evacuee boards.

By the configuration of the profile pillar 20 and the lifting sheath 30, the lifting sheath 30 is not separated from the profile pillar 20 but is moved up and down between the ceiling slab S1 and the floor slab S2.

The weight 40 is elevated along the profile column 20 and is guided to be safely elevated in the vertical direction and is embedded in the pillar hole 25 formed in the profile column so as not to be exposed to the outside. However, of course, the weight 40 may be raised and lowered in a state exposed to the outside of the profile pillar 20 rather than the pillar hole 25.

The weight 40 is for raising the lifting sheath 30, and by adding the weight, the lifting sheath 30 can be quickly raised. In addition, when installed in a high-rise building, when the distance for raising the lifting sheath 30 increases, it is possible to raise the lifting sheath 30 by using a heavier weight 40.

The winch drum 50 is rotatably installed on the bracket formed on the upper end of the pillar body 21, and the large winch drum 51 of small diameter and the small winch drum 52 of small diameter are composed of one body. The first wire 60 is wound clockwise on the drum 51, and the second wire 70 is wound counterclockwise on the small winch drum 52.

The first wire 60 is connected to the elevating skin 30 while being wound on the large winch drum 51, and the second wire 70 is weighted 40 while being wound on the small winch drum 52. It is connected with. At this time, since the winding direction of the first wire 60 and the second wire 70 is opposite, when the first wire 60 is released from the large winch drum 51, the second wire 70 is a small winch drum 52 ), on the contrary, when the first wire 60 is wound, the second wire 70 is released.

Here, since the diameter of the large winch drum 51 is larger than that of the small winch drum 52, the length of the first wire 60 being wound or unwound on the large winch drum 51 is the second wire 70 is small It is longer than the length wound or unwound on the winch drum 52. Therefore, although the distance between the weight 40 and the profile column 20 to move up and down is short, the lifting skin 30 can be moved from the bottom to the top of the profile column 20, and also the weight 40 and The friction time with the profile column 20 is shortened, and noise generation can be minimized.

The centrifugal brake 80 has a structure in which a brake shoe assembly that is axially coupled to the winch drum 50 inside the brake drum and moves toward the brake drum in centrifugal force is interlocked with the rotational speed of the winch drum 50. The braking force is provided so that the 50 rotates slowly. That is, the centrifugal brake 80 generates a large breaking force according to the rotational speed of the winch drum 50 by the descending of the lifting skin 30, thereby preventing the winch drum 50 from rotating excessively rapidly. Will be. Since the centrifugal brake 80 is a configuration generally used in the art, further detailed description will be omitted.

As described above, the evacuation member who boarded the elevating evacuation unit 30 can properly maintain the descending speed of the elevating evacuation unit 30 connected to the first wire 60 by the centrifugal brake 80. You can prevent injury. In particular, the centrifugal brake 80 is provided with a reducer, so that the winch drum 50 is not excessively rotated so that the first wire 60 is slowly released.

The shock absorber 110 is composed of a shock absorber body 111 fixed to the footrest 38 and a shock absorber rod 112 protruding to the lower side of the footrest 38 on the shock absorber body 111. By this configuration, when the lifting sheath 30 is completely lowered, the shock absorber 112 absorbs the shock applied from the floor slab S2 while being pressed against the floor slab S2, and the evacuator falls over by the impact. You can eliminate the possibility of being injured.

FIG. 10 is a view showing an excerpt of the guide handle portion of FIG. 1, FIG. 11 is a view for explaining the first operation of the guide handle portion of FIG. 10, and FIG. 12 is a diagram illustrating the second operation of the guide handle portion of FIG. 11 It is for drawing.

As shown, the guide handle portion 120 is installed on the lift evacuation portion 30 and guides the evacuee so as not to collide inside the frame housing 10 during the ascent.

The guide handle 120 is a pair of handle support rods that are pivotally coupled to both sides of the footrest bracket 121 and the footrest bracket 121 which is fixed to protrude upward to the front side of the footrest 38 of the lift evacuation part ( 122), the handle bar 123 is pivotally coupled to both ends of the handle support bar 122, and is installed between the footrest bracket 121 and the handle support bar 122 so that the handle support bar 122 maintains a certain angle It includes a first angle maintaining joint 124 and a second angle maintaining joint 125 installed between the handle support rod 122 and the handle rod 123 so that the handle rod 123 maintains a specific angle. .

The first angle maintaining joint 124 is implemented by axially coupling the disk formed on each of the footrest bracket 121 and the handle supporting rod 122, and the second angle maintaining joint 125 is the handle rod of the handle supporting rod 122 123) The disks formed on each are implemented by axial coupling. At this time, in order to keep the handle support rod 122 and the handle rod 123 at a specific angle, the faces of the opposing disks constituting the first and second angle maintaining joints 124 and 125 are formed roughly.

On the other hand, on the outer circumferential surface of the first angle maintaining joint 124, as shown in FIG. 11, two first stopper grooves 124a and 124b facing horizontal and oblique directions are formed, and the handle support rod 122 The first stopper protrusion 126 may be installed in one of the two first stopper grooves. Here, the first stopper protrusion 126 can be moved to the rear side of the handle support rod 122 by manipulation of the evacuator, and the handle support rod 122 is rotated while the first stopper protrusion 126 is moved to the rear side. After being coupled to the two first stopper grooves 124a and 124b, the handle support bar 122 can be positioned in a horizontal or oblique direction.

In addition, two second stopper grooves 125a and 125b facing a specific direction are formed on the outer circumferential surface of the second angle maintaining joint 125, and the handle bar 122 is selectively selected from any one of the two second stopper grooves. The second stopper protrusion 127 may be installed. Here, the second stopper protrusion 127 can be moved to the rear side of the handle bar 123 by manipulation of the evacuator, and the handle bar 123 is rotated while the second stopper protrusion 127 is moved to the rear side. Then, by engaging the two second stopper grooves 125a and 125b, the handle bar 123 can be positioned in a specific direction.

By the above structure, the handle bar 123 and the handle support bar 122 are folded by the first and second angle maintaining joints 124 and 125, as shown in FIG. 10, as shown in FIG. As the load is located on the lower side relative to the surface of the rim housing 10, as a result, it does not protrude to the upper surface of the ceiling slab (S1).

And in the case of emergency escape, when the evacuee grabs the handle bar 123 and lifts it to the upper side, as shown in FIGS. 11 and 12, the handle support bar 122 and the handle bar 123 maintain the first and second angle joints ( 124) It is guided so that the evacuee is positioned only on the inside of the elevating evacuation part 30 as it goes upward by the 125. Accordingly, the evacuator is prevented from being injured by striking the inner circumferential surface of the rim housing 10 during the descent process, and can be prevented from falling from the elevating sheath 30 during the descent as the holding rod 123 is held.

On the other hand, the present invention, as shown in Figure 2, the winch drum 50 is axially coupled to the power generation unit 130 for generating and charging power when rotating the winch drum 50 is installed, shown in Figure 5 As described above, a plurality of light emitting LEDs 132 that emit light by power applied from the power generation unit 130 may be installed in a plurality of grooves 131 formed at the bottom edge of the footrest 38. In this case, when the winch drum 50 is rotated in the emergency escape process, the power generation unit 130 generates power to emit a plurality of light emitting LEDs 132, so that the evacuator can safely evacuate even in a dark environment.

As described above, according to the present invention, the evacuee is evacuated by the first and second wires 60 and 70 wound in opposite directions to the winch drum 50 composed of the large winch drum 51 and the small winch drum 52. The boarded lift skin 30 may be lowered and raised. Accordingly, the spring structure such as the mainspring is not adopted, and it can be implemented in a compact structure, so that the protruding part of the ceiling slab can be eliminated, and the factor that can trip over during the escape process is eliminated and failure occurs. It is easy to maintain by minimizing, and furthermore, it is possible to prevent damage to the building exterior and increase space utilization.

In addition, since the winch drum 50 operated by the weight 40, not the spring part operated by the plate spring, is adopted as a configuration for returning the elevated skin 30 to the initial position, the ceiling slab S1 and the floor slab S2 ) Even if the distance between them has a high floor height of 5~6 m or more, installation is possible.

In addition, by the guide handle 120, the evacuee can be positionally guided so as to be positioned only on the inside of the elevating evacuation part 30, thereby preventing the evacuator from being injured by hitting the inner circumferential surface of the edge housing 10 during the descent process. , As holding the handle bar 123 and supporting it, it is possible to prevent the fall from the lifting sheath 30 during the descent.

In addition, by having a structure in which the footrest 38 and the weight 40 are wound on each winch through each wire, after fixing the footrest 38 and the weight 40 to one end of each wire, each wire Through a simple operation of fixing each winch to the other end, the wire connection can be made very easily.

Then, the step 38 is lowered from the top of the profile column 20 to the bottom at a constant or safe speed and rapidly returns from the bottom to the top.
