FIG. 2 and FIG. 3 are perspective views showing an emergency escape apparatus according to an embodiment of the present invention before and after operation.

The emergency escape apparatus 100 according to the embodiment of the present invention is installed in a platform of a ship residence as shown in FIG. 1, and when the door of the ladder is unlocked by driving the driving unit, the emergency escape ladder So that it can be used as an emergency escape route.

2 and 3, the emergency escape apparatus 100 includes a ladder storage 110, an emergency ladder 200, a driving unit 120, a door gripper 130, a support unit 132, and a grip unit 134 do.

The ladder storage box 110 is an empty box, and the emergency ladder 200 is accommodated therein. On the front surface of the ladder storage box 110, a door 112 which can be opened and closed is provided. The upper portion of the door 112 is hinged and can be rotated 90 degrees about the hinge axis to open or close the internal space of the ladder storage box 110.

Although the door 112 is illustrated as being hinged at the top, it is to be understood that the door 112 is merely an embodiment and may be hinged at the bottom.

The emergency ladder 200 may have a rope ladder 220 wound around a cylindrical winding section 210 and stored in the ladder storage box 110. One end of the rope ladder 220 may be fixedly coupled to the inner rear surface of the ladder storage 110, and the other end may be coupled to the winding portion 210. When the door 112 is unlocked, the winding unit 210 advances to the outside of the ladder storage box 110 by its own weight, and the rope ladder 220 unfolds to function as an emergency escape means.

A driving part 120 is installed on the rear surface of the ladder storage 110 and a door gripper 130 for opening and closing the door 112 is installed on the driving part 120. The door gripper 130 includes a supporting portion 132 hinged to the driving portion 120 and a grip portion 134 bent at 90 degrees from the end of the supporting portion 132 and has an L-shaped cross section.

The grip portion 134 is bent toward the door 112 when the support portion 132 is adjacent to the side surface of the ladder storage box 110 so that the door 112 is prevented from rotating around the hinge axis, (See Fig. 2).

When the supporting part 132 is rotated and moves away from the side surface of the ladder case 110, the grip part 134 is also distant from the door 112 to prevent the door 112 from being caught and the door 112 to be closed. In this case, the emergency ladder 200 stored in the ladder storage box 110 can push the door 112 out (see FIG. 3).

An inclined plate 114 having a predetermined inclination may be provided on the inner bottom surface of the ladder case 110. The swash plate 114 has a high rear portion and a low front portion so that the winding portion 210 of the emergency ladder 200 slidable by its own weight can advance to the front side. That is, the swash plate 114 assists the emergency ladder 200 to spread even when the degree of inclination of the offshore structure 10 is not severe.

Hereinafter, the driving principle of the driving unit 120 for rotating the door gripper 130 will be described with reference to the drawings.

FIGS. 4 and 5 are views showing a state before and after a driving unit of the emergency escape apparatus according to an embodiment of the present invention is driven, and FIG. 6 is an enlarged side view of the bearing force providing module.

4 and 5 show the ladder storage 110, the emergency ladder 200, the winding part 210, the rope ladder 220, the door 112, the door gripper 130, the support part 132, the grip part 134, The hinge 136, the driving unit 120, the driving unit body 300, the spring 302, the push button 316, the through hole 322 for the button, and the module bodies 310, 310a and 310b 306a, 306b, hereinafter also referred to as "306"), a liquid material receiving portion 314, a storage space 312 (also referred to as " (Also collectively referred to as '312'), liquid material discharge holes 320, 320a and 320b (also collectively referred to as '320'), and an ampule 308 are shown. It is assumed that the upper side corresponds to the rear side and the lower side corresponds to the entirety.

The driving unit 120 is installed on the rear surface of the ladder storage box 110 and includes a driving unit body 300 in which one end of the supporting part 132 of the door gripper 130 is received. One end of the support portion 132 is rotated about the hinge 136 and one end thereof is accommodated in the drive unit body 300 so that the rotation of the support portion 132 is controlled by the restoring force of the spring 302 and the supporting force of the support rod 304,

Spring supporting portions are provided at both ends of the driving unit body 300 so that the spring 302 can be interposed between the supporting portion 132 and one end. The spring 302 may be a compression spring, which may provide a restoring force in the unfolding direction when compressed. In this embodiment, the direction of the restoring force may be the direction toward the center of the driving unit body 300.

A supporting force providing module may be provided at an inner center portion of the driving unit body 300 and a supporting rod 304 may be extended toward both sides of the supporting force providing module.

The end of the support rod 304 supports one end of the support portion 132 of the door gripper 130.

That is, the spring 302 and the support rod 304 are opposed to each other with one end of the support portion 132 as the center, and the support rod 304 maintains the restoring force by the spring 302 to keep the door gripper 130, So that the door lock state can be maintained (see FIG. 4).

However, when the support force provided by the support force providing module is lost, the support rod 304 is pushed by the restoring force of the spring 302 to the center of the drive unit body 300 so that the door gripper 130 moves the hinge 136 to the center The door lock state is released, and the state can be switched to the door open state. In this case, the winding unit 210 inside the ladder storage box 110 pushes the door 112 and advances to the outside to unfold the rope ladder 220 (see FIG. 5).

The supporting force providing module includes a module body 310 in which a storage space 312 for storing the liquid material is formed.

The storage space 312 is a space in which one side is opened, and a support plate 306 provided at an end of the support rod 304 is slidably coupled to the opened side. The interior of the storage space 312 is completely closed by the support plate 306, and liquid material may be filled in the storage space 312. The support rod 304 connected to the support plate 306 due to the hydraulic pressure of the liquid material overcomes and restores the restoring force of the spring 302 so that the door gripper 130 can be in the door lock state.

The storage space 312 may have various shapes such as polygonal, circular, and elliptical shapes corresponding to the shape of the support plate 306 (see FIG. 6).

A liquid material discharge hole 320 may be formed in the other side of the storage space 312 and an ampule 308 may be provided outside the liquid material discharge hole 320. The inner space of the ampule 308 communicates with the storage space 312, so that the liquid material can freely pass through.

A push button 316 may protrude from a rear surface of the driving unit body 300 in correspondence with a position where the ampule 308 is installed.

The push button 316 has a pointed tip 318. When the push button 316 is pressed by an external force, the tip portion 318 exerts an external force on the ampule 308, and the ampule 308 made of a material easily broken by an external force such as glass can be broken.

When the ampule 308 is broken, the liquid material in the storage space 312 communicating with the ampule 308 can be discharged from the storage space 312 through the damaged portion. As the liquid material flows out of the storage space 312, the supporting force applied to the support rod 304 is reduced and the restoring force of the spring 302 is relatively increased. Thus, the support part 132, that is, the door gripper 130, The door lock state can be released (see FIG. 5).

The liquid material flowing out along the damaged portion of the ampule 308 may flow into the liquid material receiving portion 314 of the module body 310 and be accommodated.

Since the emergency escape apparatus 100 according to the present embodiment operates mechanically without using electricity, the emergency escape apparatus 100 according to the present embodiment is characterized in that it is suitable for emergency escape when its operation is ensured even when electricity is cut off due to an emergency situation in an offshore structure.

Although the description has been made on the case where the liquid material is used as a means for providing the support force in the support force providing module, this is merely an example. However, in addition to the liquid material, compressed air or the like capable of providing a predetermined- May be used in place of the above.

Although the present embodiment has been described on the assumption that there are two door grippers, it is possible to control the opening and closing of the door even when the door gripper has one door. In this case, it is needless to say that only one side portion of the driving unit described in the symmetrical structure may be provided.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the following claims And changes may be made without departing from the spirit and scope of the invention.
