An emergency descender that can be carried and used.

In general, in the event of a fire, distress at sea or distress in the mountains, professionally trained rescue workers will rescue and save lives.

However, because this situation is urgently occurring and the situation develops in an instant, many lives are injured before rescue workers are dispatched. In preparation for this situation, high-rise buildings have emergency descents around the window frames. In such a conventional emergency descender, in particular, a descender using a rope, a friction braking device is coupled to the rope, or a roller is wound around the brake shoe and the user manually brakes the brake. There was a fear of descent because there was no mental room to operate the device, and women and the elderly had a problem that it was virtually impossible to safely descend due to the weak power to operate the manual braking device.

In order to solve this problem, an emergency descender has been developed in which the rope is automatically unwinded. As shown in FIG. 1, the conventional emergency lowering machine is provided with a driving pulley 20 and a driven pulley 30 in a frame formed inside the outer case 10, and the driving pulley 20 and the driven pulley 30. The prime mover 21 and the reduction gear 31 are formed at both sides of the. Then, the drum 40 is wound around the inner case 10, the rope 50 is wound, the rope 50 is released from the drum 40 is driven to the driven pulley 20 and driven pulley 30 Each is wound, and a fastener 51 is formed at the end of the rope 50. In addition, a band brake 41 is formed at one side of the drum 40, and one end of the band brake 41 is connected to the emergency braking strap 42 formed by extending to the outside of the outer case 10.

Emergency lowering device configured as described above is accommodated in the backpack (not shown), in the emergency to fix the fixture of the rope to the fixture, when the jumping down the backpack containing the emergency lowering device is applied to the rope 50, the tensile force is applied to the rope 50, Is released from the drum 40 while rotating the prime pulley 20 and the driven pulley 30. At this time, the rotational force is transmitted to the driving gear 21 and the reduction gear 31 coupled to both sides of the driving pulley 20 and the driven pulley 30 to control the loosening of the rope 50 to loosen the rope 50. It will be made slowly so that you can safely descend to the ground. In addition, the band brake 41 may be operated to stop or lower the lowering speed during the lowering.

Such a conventional emergency descender is designed to put the descender in a backpack, so it cannot be carried because it is bulky, and should always be provided at emergency exits such as windows of buildings, and it is difficult to carry because of the bulky emergency descender. There was a problem that could be used.

In addition, there is a problem in that the structure of the emergency lowering machine is complicated to increase the production cost during production, which is a major cause for the general public is reluctant to purchase.

The present invention has been devised to solve the problems as described above, by improving the structure of the descender with a rope embedded therein can escape the emergency or emergency in emergency situations such as fire, distress, etc. without a separate rope, An object of the present invention is to provide an emergency lowering machine that can be easily carried and used in ordinary times.

First, the components formed inside the outer casing 100 will be described. The outer casing 100 has a hollow shape inside, can be hand-made for easy portability, and the size can be carried on the waist dance. A fixing plate is installed at the lower portion of the outer case so that the first fixing ring 101 under load is fixed firmly, and the first fixing ring 101 is fixed to the outer casing 100 and the fixing plate. This is to effectively receive the load during the emergency descent. And, a through hole 102 is formed in the upper portion, the gear cover 110 is installed on one side.

The roll drum 200 is rotatably fixed to the inside of the outer casing 100, and guide plates 201 are formed at both sides thereof. One end of the wire rope 210 is fixed to the outer circumferential surface of the roll drum 200, and the wire rope 210 is wound around the roll drum 200. In addition, one side is coupled to the first gear 300, the other side is the rewinding knob 130 is coupled to the outer casing 100 outside.

One end of the wire rope 210 is fixed to the roll drum 200 and wound around the roll drum 200. In addition, a second fixing ring 211 is formed at the other end, and can be fixed to an external fixture. The wire rope 210 is made by twisting a plurality of strands by combining a steel wire having a fine outer diameter, which has the advantage of being able to withstand more load than using the steel wire itself. Such wire rope 210 has an outer diameter of about 3 mm, can withstand a load of 200 kg or more, and the length can be arbitrarily specified. The war rope is a steel wire, but has a predetermined ductility and is wound around the roll drum 200.

The pressing plate 120 serves to closely adhere the wire rope 210 to the roll drum 200 so that the wire rope 210 can be closely wound. This prevents the wire rope 210 from being unwound in an unwound state, and the wire rope 210 is constantly unwound by an external force by keeping the wire rope 210 constantly wound. The pressing plate 120 is the front of the wire rope 210 is pressed, a plurality of fixing rods 211 is formed on the back. The fixing rod 211 is fixed to the fixing guide 103 formed inside the outer casing 100, and an elastic spring 122 is formed at the outer circumference of the fixing rod 211 to provide an elastic force to the pressing plate 120 to compress the pressing rod. The plate 120 compresses the wire rope to prevent the wire rope from being unwound in an unrolled state in the roll drum.

Guide member 500 is formed on the upper side of the roll drum 200, so that the unwinding or winding of the wire rope 210 released from the roll drum 200 can be made efficiently. The guide member 500 is fixed to the inside of the outer casing 100, one side of which is inserted through the guide rod 510 and the guide rod 510 formed with the groove 511 on the outer circumferential surface of the guide casing 511 to the left and right. It consists of a guide piece 520 to flow. The guide rod 510 is formed on the outer circumferential surface so that a pair of grooves 511 intersect at a plurality of points, and rotates in conjunction with the roll drum 200 released from the roll drum 200 by an external force. And, the guide piece 520 is formed in the groove 511 formed in the guide rod 510 in the through-hole 102 is formed to be inserted into the guide rod 510 so as to flow in one side of the through-hole 102. The guide bar is formed to be hooked, so that when the guide rod 510 is rotated, the guide rod flows from side to side along the groove 511 so that the wire rope 210 released from the roll drum 200 is constantly released. The guide member 500 flows left and right while guide rods are guided to a pair of grooves 511 intersecting at a plurality of points irrespective of the rotation direction of the guide rod 510.

Next, the gears formed on one side of the outer casing 100 will be described.

The first gear 300 is connected to one side of the roll drum 200 is rotated in the same manner as the roll drum 200 is rotated by the loosening of the wire rope (210). The first gear 300 is the same as the gears generally used, and a high strength material is used because the volume of the first gear 300 must be small.

The reduction gear group 320 is formed on one side of the first gear 300, the first reduction gear 321, the second reduction gear 322, the third reduction gear 323 and the third reduction gear 323 Is formed on one side of the control pin 324 for controlling the rotation of the third reduction gear 323 is made. The first, second, and third reduction gears are made of the same material as the first gear 300, and the rotational speed transmitted from the first gear 300 is different from the first gear 300 by the gear ratio. In order to reduce the unwinding speed of the wire rope 210 released from the roll drum 200 connected to the first gear 300 while being transmitted in the order of three reduction gears. The control pin 324 is installed outside the third reduction gear 323. The end of the control pin 324 has a shape corresponding to the thread formed on the outside of the third reduction gear 323, the other end is fixed to the outer casing 100 to be rotatable, the elastic spring ( Not shown) is installed. The control pin 324 as described above is caught by the gear mount of the third reduction gear 323, the rotation is stopped by the elastic force of the elastic spring (not shown) when the third reduction gear 323 is rotated by the external force is applied. When the elastic threshold of the elastic spring (not shown) is exceeded, the end portion is released. In addition, the end of the gear is repeatedly caught by the elastic force of the elastic spring to reduce the rotation speed of the third reduction gear 323.

The second gear 310 rotates in engagement with the first gear 300 and is connected to the guide rod 510 of the guide member 500. When the first gear 300 is rotated when the first gear 300 is rotated, the guide piece 520 flows from side to side along the guide rod 510 by rotating the guide rod 510.

The gear cover 110 is coupled to one side of the outer casing 100 to protect the gears such as to seal the gears.

The stop member 400 is formed outside the gear cover 110 and is connected to the first gear 300. The stop member 400 includes a stop gear 410 and a stopper 420. Storm gear is formed on the outer circumferential surface of the locking step 411 and the gear mountain formed with a sliding inclined surface to the outside of the locking step 411. And, the stopper 420 is formed so that the end is caught on the locking jaw 411 and is configured to release the locking. The reason is that the stopper 420 is released from the catching jaw 411 when the emergency descends, and the stopper 420 is caught by the catching jaw 411 when it is necessary to stop the falling in an urgent situation. to be.

Then, the folding handle 130 is formed on the outer casing 100 on the other end side of the roll drum 200. The handle 130 is rotated in the same way as the roll drum 200 because one side is combined with the roll drum 200, the other side is folded when not in use, when used to expand the folded handle 130. The handle 130 is installed to re-wind the wire rope 210 released from the roll drum 200 to the roll drum 200 after using the descender in an emergency situation.

It describes the operation of the portable emergency lowering device according to the present invention having the configuration as described above.

The portable emergency lowering device as described above is usually carried in a waist dance or a pocket, and when an emergency occurs, the first fixing ring 101 formed at the bottom of the outer casing 100 is part of the body (waist, chest, etc.). After fixing to the second fixing ring 211 formed at the end of the wire rope 210 is fixed to the fixture. Then, when jumping off the building, the load is applied to the wire rope 210 by the weight of the user, the wire rope 210 is released from the roll drum 200 by the load. At this time, as the wire rope 210 is released from the roll drum 200, the roll drum 200 is rotated and the first gear 300 is rotated. The rotation speed of the first gear 300 is reduced by the high gear ratio while the rotation of the first gear 300 is transmitted to the first, second and third reduction gears of the reduction gear group 320 having different gear ratios. Unwinding of the wire rope 210 to be released at 200 is made slowly. In addition, it is possible to finally control the loosening of the wire rope 210 by the control pin 324 formed on one side of the third reduction gear 323. This operation allows the user to safely descend to the ground.

In addition, the stop member 400 formed on one side of the outer casing 100 can stop the descender by engaging the scope to the locking step 411 of the stop gear 410 when the situation to stop the descender during the lowering. .

As the above-mentioned descender is small in overall volume, it can be easily carried, so it is not only used in high buildings or rock walls, but also without the need for a separate rope in case of distress caused by waves when fishing on the beach. By dissipating the wire rope 210 inherent to the lowering device that can be easily carried on the waist dance, rescue the distress within a short time.

As described above, according to the portable emergency lowering device according to the present invention, there is an advantage that can escape the emergency or rescue lives in an emergency situation such as fire, distress, etc. without a separate rope.

In addition, since the volume is small, it can be conveniently carried in a waist dance or a pocket in ordinary times, and there is an advantage in that it can be used to save lives by using it quickly in case of an emergency.
