Description

[Detailed description of the invention] (Field of industrial application) This invention can be attached to any part of a descending strip suspended from a high place on a building, and can be adjusted to a safe location while adjusting the descending speed. This relates to a descent evacuation device that allows descent.

(Prior art) In recent years, buildings have become more and more high-rise, and many people use these high-rise buildings as residences and hotels. However, when a disaster such as a fire occurs on the upper floors of a high-rise building, The current situation is that ladder trucks and other rescue vehicles are unable to reach the upper floors, resulting in tragic accidents in which precious lives are lost. Therefore, for example, Utility Model Application No. 49-5300, Utility Model Application No. 50-27698, or Utility Model Application No. 53-
Various evacuation devices have been proposed, as disclosed in Publication No. 93000.

(Problem that the invention aims to solve) However, most of the various evacuation devices mentioned above use centrifugal brakes to suppress acceleration due to gravity when descending along a rope, for example, and the structure is There are problems such as being complicated and bulky, difficult to operate, and inconvenient to store when not in use. Furthermore, for example, when descending along the rope, the rope must be passed through the evacuation equipment in advance, and it is not possible to attach the evacuation equipment to the rope midway through the rope suspended from a high place. There is also the problem that it is extremely difficult.

(Means for solving the problem) The present invention solves the problem,
It has a simple structure and is compact, and can be easily attached to any part of the descending strip installed along the outer wall of a building, and can be moved to a safe place while adjusting the descending speed by gripping with your fingers. The purpose is to provide a descent evacuation gear that can be descended.

That is, the present invention provides a rope wheel that clamps a descending strip of an appropriate thickness between opposing substrates of required dimensions, and a braking device is interlocked with the rope wheel by a gear train, and the braking device can be controlled remotely. This descending evacuation device includes a braking device that allows the user to descend along a descending strip while adjusting the braking force by gripping a lever with his or her fingers. Therefore, the present invention is an evacuation device that can be attached to a descending strip suspended from a high place and can be lowered at a safe speed along this descending strip, and that is capable of lowering the evacuation device between opposing substrates. A first gear consisting of a rope wheel on one side of a pair of rope wheels for holding a descending strip body of an appropriate thickness, and appropriate gears superimposed on the upper and lower surfaces of the rope wheels is attached to the shaft. A gear train is engaged with the first gear to form a speed-increasing gear train, and the last gear of the gear train is a braking device that normally stops the rotation of the gear train. A pulley on which a descending strip is hung is provided near the gear train and the braking device, and a pulley on which the descending strip is hung is provided near the gear train and the braking device. An induction gear on which a rope wheel is attached is inserted into a shaft body, and the shaft body into which this induction gear is inserted is pivotally supported by a shaft installed between opposing boards and has a required length. , and is supported by a hinge with elasticity so that the induction gear can freely engage with the first gear, and is provided with a deflectable arm that supports the shaft of the induction gear with the shaft as a fulcrum, and this arm A grip bar and an operating lever communicating with the braking device are provided on the extension of the rope, and a notch with a width that allows the descending strip to be introduced between the opposing base plates is provided at the side of each rope car. is provided on one board.

(Function) The function of the descent evacuation device of the present invention will be explained (see Figures 4a and 4b, Figures 5 and 6).
Since the descending evacuation device A is constructed as described above, the rope R serving as the descending strip is connected to an appropriate location on the building, and the rope R is suspended downward.
Then, by tilting the arm 16 of the descent evacuation gear A toward the right side in the drawing, the guide gear 11 separates from the first gear 3 to form a gap, and an arbitrary part of the rope R is introduced into the gap, and the two rope wheels 3a , 11a
The rope pulleys 3a, 11a reliably clamp the rope R by locking the arms 16 to the pulleys 10 and returning the arms 16 to their original positions. Furthermore, as shown in FIG. 5, for example, a holding body 30 is formed of something like a narrow band 31, and by hanging the holding body 30 at an appropriate position of the descent evacuation device A, a stable state can be maintained. By folding the holding body 30 into a small size when not in use, it does not get in the way of storage. Then, as shown in FIG. 6, the user can transfer his/her body to the holder 30 of the descent evacuation tool A to which the rope R is attached, and be able to grasp the grip bar 17. At this time, the descending evacuation gear A is in a stopped state, so the previous movements can be performed easily without any problems, and the body is moved to the arm 16.
Since the rope R is held in a tensioned state, the descending evacuation gear A can securely hold the rope R.
Then, by grasping the operating lever 18 with your fingers, the braking force of the braking device 7 is slightly reduced, so the rope cars 3a and 11a can be rotated, and the descending evacuation gear A
The person can gradually descend along the rope R and evacuate to a safe place.

(Effects of the invention) The descending evacuation device of the present invention can be extremely easily and stably attached to any part of the descending strip installed at an appropriate location such as along the outer wall of a building, and It securely clamps the body and allows descent at a safe speed, and has a simple structure that anyone can easily operate. Therefore, it can be attached not only from the tip of the rope but also at any point along the way, allowing the evacuee to descend while adjusting the descent speed, regardless of the weight of the person evacuating. This provides a sense of security, and since it is easy to operate, anyone can use it.
Since the structure is simple and compact, it is convenient for storage and has great practical effects.

(Example) Next, an example of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, multiple grooves are carved on the left side of the opposing substrates 1 and 2 of the required dimensions on the surface where the descending strip, e.g., the rope R, comes into contact with, so that the rope R can be held between the legs. A reliable rope wheel 3a is provided, and a gear 3b with rounded tooth tips to facilitate meshing with the adjacent gear 11b is provided on the upper surface thereof, and a gear 3b with a larger number of teeth and a larger pitch circle than the gear 3b on the lower surface. 3c is attached to the rope wheel 3a so that the first gear 3 has a common shaft attached to the rope wheel 3a. A second gear 4 which is a small gear is provided at a position adjacent to the gear 3c, a gear 5b having approximately the same size as the second gear 4 is provided at a position adjacent to the second gear 4, and a large gear 5a is provided above the second gear 4.
A third gear 5 is mounted on the shaft, and a small gear 6a that meshes with the large gear 5a is provided at a position adjacent to the third gear 5, and a middle gear 6b is mounted on the lower part. A gear train is formed by pivoting the fourth gear 6. A brake gear 7' having approximately the same size as the intermediate gear 6b is pivotally attached to a position adjacent to the intermediate gear 6b in the gear train, and the brake gear 7' is covered with a casing 7a as shown in FIG.
A plurality of disks 7b form a clutch and are housed inside the casing 7a. When supporting the brake gear 7', a spring body 7d is inserted into the shaft 7c having a spiral cut thereon, and a sleeve 7e is screwed onto the shaft 7c to complete the braking device 7.
form. The brake lever 8 protruding from the sleeve 7e is always kept in tension by a tension spring 8', that is, the spring body 7d and the sleeve 7e
By strongly pressing the disk 7b at the end of the brake gear 7', the brake gear 7' is always in a braking stopped state and does not move even slightly. Because it is a gear train,
The rotational force applied to the first gear 3 is attenuated as it is transmitted to the braking gear 7', and braking is reliably performed with a small force. A rope R is guided near the gear train,
The pulley 1 also includes a safety claw 10' to prevent the main body from falling when attached to the rope R upside down.
0 is mounted on the shaft. Then, an induction gear 11 is formed by superimposing a gear 11b and a rope wheel 11a having the same shape as the upper gear 3b and rope wheel 3a of the first gear 3, and a shaft 12 fitted into the induction gear 11. A shaft 13 installed at the center of the lower part between the opposing substrates 1 and 2 is supported by hinges 14, 14 of a required length, and at the same time, the hinges 14, 14 are supported by the repulsive force of a coil spring 15 inserted through the shaft 13. The upper gear 3b of the gear 3 and the upper gear 11b of the induction gear 11 are always in mesh with each other. At this time, the induction gear 11 is placed on the line connecting the axis of the first gear 3 and the axis of the shaft 13, that is, beyond the dead line L by θ degrees to stabilize the clamping action. Next, an arm 16 is provided which is connected to the shaft body 12 fitted into the induction gear 11 using the shaft 13 as a fulcrum, and is extended downward by an appropriate length from the fulcrum position of the arm 16, and the tip of the extended arm 16 is A grip rod 17 is attached to the grip rod 17, and a well-known operating lever 18 is provided on the grip rod 17, and this operating lever 18 is connected to a loosening lever 9 provided on the sleeve 7e by a cable release 9'. By gripping with fingers with a force stronger than the tension of the tension spring 8', the sleeve 7e rotates in the direction of loosening, and the disc 7b
The pressing force on the rope wheels 3a, 11a is thereby gradually rotated. Further, on one of the opposing substrates 1 and 2, for example, the front substrate 1, a rope R is introduced between each substrate 1 and 2 on the side of the part where each rope wheel 3a, 11a is joined, and each A notch 1' with a width that allows the rope wheels 3a and 11a to be fitted is bored, and appropriate elongated holes 1'' and 2' are bored in the opposing substrates 1 and 2 on the movement line of the induction gear 11, and the structure is simple. This is a descent evacuation device A that is configured to be easily operated.

In addition, the descending evacuation device of this invention can also be used by resting the body directly on the grip bar without hanging the holder.
It goes without saying that the technical scope of the present invention also applies to single-plate braking devices in addition to multi-plate braking devices.
