Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a descent device used in an emergency.

[0002]

2. Description of the Related Art In the case of a rope used in an emergency, stability is lacking in terms of holding a body.

[0003]

Therefore, the present invention has been made to solve the above-mentioned drawbacks.

[0004]

Now, the structure will be described. (A) A spring 2 is provided inside the descending device 1. (B) A lever 3 for changing the diameter of the spring 2 is provided. The device is operated as described above.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a pipe 4 penetrates a spring 2 provided inside a descent device 1. This pipe 4 corresponds to a conventional rope. One end of the spring 2 rotates together with the rotating body 5, and at this time, the diameter of the spring 2 changes. This figure shows a situation where the diameter of the spring 2 after rotation is reduced, that is, the spring 2 and the pipe 4 are in close contact with each other and the descending device 1 does not drop. The rotating body 5 is rotated by operating the lever 3 integrated therewith, and a grip 6 is provided to efficiently perform the operation. When using the descent device 1, the lever 3 is first pulled, the grip 6 is held with the right hand, and then the body is brought into close contact with the descent device 1 in a hugging condition. Thereafter, the falling speed of the descending device 1 is adjusted by adjusting the lever 3 to loosen. Since the body and the descending device 1 are in close contact with each other, it is safer to seal the spring 2 inside the descending device 1.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, a rope 7 is bound to the head of a descending device 1. This is for raising the descent device 1 after the body lands. After the landing, the body separates from the descending device 1, but at the same time, the lever 3 returns so that the diameter of the spring 2 increases. As a result, the rescue operation can be performed promptly. It is convenient to use a storage type in which the pipe 4 is divided into fixed lengths and a rope is passed through the pipe.
The whole can be formed smoothly.

[0007]

As described above, the use of the descent device 1 enables a more stable descent than the conventional one using a rope, but on the other hand, the body can be lowered in a situation where it is hugged by the descent device 1. Therefore, when the rope is used, it is effective without causing damage due to friction between the body and the rope.

In FIGS. 4 to 6, the lowering device 1 is stopped by pushing down the lever 3, whereas in FIG.
1 shows that the lowering device 1 is lowered by pushing down the lever 3. A portion where the rotating body 5 does not function is omitted, and a spring 19 is provided in the space, and the rope 19 becomes entangled with the spring 19 via the rotating body 5 and the outer frame side, and the descent device 1 is in a stopped state. Although the adjusting plate 20 having a plurality of holes is provided on the outer frame side, the degree of the entanglement of the rope 11 can be changed by changing the hooking position of the holes. Further, by utilizing the fact that the adjusting plate 20 is a projection, an appropriate position is determined so as to function as a stopper against excessive turning of the lever 3. The method of lowering the lowering device 1 by depressing the lever 3 as described above has a merit that an accident due to an erroneous operation of a person unfamiliar with the lowering device 1 can be prevented beforehand, and FIGS.
It can also be introduced to the configuration shown in FIG. However,
The configuration shown in FIGS. 1 to 3 is not suitable for repeated use because the descent device 1 and the pipe 4 are fixed at the end of the descent when the body lands and cannot be lifted up with the rope 7. In order to solve this problem, it is necessary to turn the lever 3 again at the end of the descent and fix the lever 3 so that the position can be maintained, for example, to insert a pin.

FIG. 10 is a front perspective view based on FIG. 1, in which the lowering device 1 descends when the lever 3 is pulled. At the time of landing, the descent device 1 is pulled up by the rope 7, but in such a situation, the diameter of the spring 2 needs to be increased. In this figure, it is possible to maintain the increased diameter of the spring 2 by inserting a pin 25 that engages with the hole 24 provided in the rotating body 5 in the limit state where the lever 3 is pulled.
Further, by screwing the cap 26 into the bottom of the descending device 1, the rotating body 5 presses the spring 2, and the rotation of the rotating body 5 becomes stable. That is, by adopting this configuration, the step of mounting the rotating body 5 inside the descending device 1 can be simplified. This also allows the spring 2 to be replaced smoothly, which is effective for maintenance and inspection.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a descent device used for evacuation during a disaster.

[0002]

2. Description of the Related Art In some cases, a rope is used for evacuation in the event of a disaster, and descends while being entangled with the rope from the upper floor.

[0003]

In the case of descending while being entangled with the rope, if the entanglement between the person and the rope is increased, the stability increases but the descending ability decreases. Also, if the entanglement between the person and the rope is weakened, the descent ability is increased, but the stability is weakened, and the person is exposed to the danger of falling.

[0004]

A spring 2 is provided inside a lowering device 1 and a lever 3 for changing the diameter of the spring 2 is provided. Since the pipe 4 penetrates through the spring 2, the descent device 1 enables the descent between the pipes 4. However, it is necessary to stop the descent device 1 and suppress the descent speed. To ensure uniform tightening.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a pipe 4 penetrates a spring 2 provided inside a lowering device 1. The lowering state of the lowering device 1 depends on the degree of tightening of the spring 2 with respect to the pipe 4. Is to adjust. Tightening of the spring 2 is performed by holding the lever 3 and the grip 6 by hand through the rotating body 5 to which the upper end of the spring 2 is fixed, and stopping the descent by pulling the lever 3 and
This controls the descent speed. In use,
The person on the floor first pulls the lever 3 sufficiently to form a strong tightening of the spring 2 against the pipe 4. In this state, the person shifts to the descending device 1 and thereafter descends while adjusting the tightening of the spring 2 according to the situation of the disaster.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a lever 3 and a grip 6 are arranged at the upper end of a lowering device 1 to create a situation in which the lowering device 1 can be in close contact with the body of a person. Further, a rope 7 for lifting the descent device 1 is provided. That is, when the person lands using the descent device 1, the person on the floor can lift the descent device 1 using the rope 7 and use it again for descent. Also, the pipe 4 is of a split type, and a rope 8 is passed through all the split pipes 4.
It forms a pipe 4 used for descent. In addition,
In FIG. 1, in order to write the rope 8, the rope 7 is illustrated so as to avoid the center line of the descending device 1. This pipe 4 is chamfered at its tip so that the entire pipe 4 can be formed smoothly. That is, for example, when this descending device 1 is used in a building fire, the pipe 4 is easily affected by convection in the building wind and the hot wind. As a result, a large amplitude is generated in the entire pipe 4 and the descent is dangerous, but the same applies to the pipe 4 having a high degree of adhesion between the pipes 4 and without the chamfering process. In this regard, since the chamfered pipes 4 do not have close contact between the pipes 4 and disperse the wind power, the entire pipes 4 can maintain a relatively stable state.

[0007]

(A) Since the surface of the pipe 4 is a smooth surface, there is no resistance between the spring 3 and the pipe 4 and the lowering device 1
Can be reliably performed by stopping the spring 3 uniformly on the pipe 4 when stopping. (B) When descending while being entangled with a rope, it is difficult to bring a person into close contact with one rope, and even if the entanglement is increased, the descending ability is inferior. On the other hand, in the case of the descending device 1, it is easy to bring a person into close contact with the descending device 1, and the spring 2 and the pipe 4
Has a high descent ability due to the interaction of. (C) When descending while being entangled with the rope, skin damage may be caused by friction in the tight contact state between the rope and the person. In the case of the descending device 1, friction occurs in the tight contact state between the descending device 1 and the person. Is completely absent and safe. (D) The ropes and rope ladders are easy to fall when blown by the wind and are dangerous, and the material is flammable. However, in the case of the descent device 1, it copes with the wind pressure by its own holding capacity and the chamfer pipe 4 It is easy to make the device 1 and the pipe 4 flame-retardant.
