Description

[Detailed Description of the Invention] (Industrial Application IF) The present invention uses an eddy current brake in a descending device for a person descending from a high place such as a building when a disaster such as a fire occurs,
Automatically limits descent speed to ensure safe descent, and
This invention relates to a device that facilitates descent.

(Prior Art) Conventionally, when a disaster such as a fire occurs and a person is stranded in a high place in a building, a hanging rope ladder or the like is often used to escape by descending from that place. However, when descending and escaping using a hanging rope ladder, the person descending and the person operating the hanging rope ladder must:
Both had the disadvantage that it was difficult to descend safely unless well trained, and it was impossible to descend depending on the physical ability of the person descending.

(Objective of the Invention) The present invention aims to achieve the effect that when a disk placed in a magnetic field is rotated by an external force, the eddy current flowing in the disk brakes the external force (7). By providing a descent device using eddy current brakes that can be adjusted to automatically limit the rate of descent when descending from a height, making the descent easier and safer, The purpose is to make it possible to adjust the descent speed limit according to the person's weight.

(Structure of the Invention) In order to achieve the object of the present invention, the present invention provides an eddy current brake that generates braking force in response to external torque and that can arbitrarily adjust the braking force. a speed increasing gear device connected to the rotating disk of the eddy current brake to rotate the rotating disk; and a speed increasing gear device releasably connected to the input side of the speed increasing gear device and having a hook attached to one of the terminal parts. A cable drum that can pull out and unwind the cable, and a case that houses the cable drum and has a grip bar and hanging rope to support the body during descent. It uses brakes and is also a descent device.

('4! Embodiment of the Invention) The structure of an embodiment of the present invention will be explained with reference to FIGS. 1 to 5.

As shown in FIGS. 1 and 2, a descending device using an eddy current brake as an embodiment of the present invention includes an eddy current brake section 1, a speed increasing gear box 2, and a speed increasing gear box. 2 and a cable drum 6 connected by a knob 4, and a case 5 that covers the cable drum 6.

The eddy current type brake section 1 is shown in FIG.
- As shown in FIG. 3 showing the A cross section, an eddy current is generated between the yoke A11 and the yoke B12, in which a plurality of permanent magnets 13 are attached at approximately equal intervals on the circumference. The disc 14 is directly connected to the final 1i32 gear of the speed increasing gear box 2, which is made up of a disc 14Vi and a plurality of gears (not shown). By rotating, the disk 14 rotates at an increased rotational speed. As shown in FIG. 4, the magnetic circuit for causing an eddy current to flow through the disk 14 is as follows: permanent magnet 16 → disk 14 → yoke A11 → yoke B1
2 occurs.

Yoke A11 accelerates I'm-S! The yoke B12 is integrated with the yoke A12 by screws or the like, and is fitted into the yoke A11 so as to be rotatable on the inner diameter side of the yoke A11 and slidably in the axial direction.

The rat shaft 17 is connected to the yoke B12 by the pin 18.
When integrated with the cover 19, the cover 19 is engaged with the screw T420.

A brake adjustment knob 21 for adjusting the amount of braking of the eddy current player is fixed to the latch shaft 17 by a pin 22, and by turning the brake adjustment knob 21, the difference between the yoke B12 and the disc 14 is adjusted. It is formed so that the air gap can be adjusted. Also, the latch machined into the threaded part 20 of the latch shaft 17? Jf23 and'
Yoke B12 and disk 1 by Y-notch 24
It is possible to maintain a constant air gap between 4 and 4.

Next, as shown in FIG. 2, the cable drum 6 is wrapped with a cape (v26) with a hook 25 attached to its tip, and is directly connected to the input shaft 15 of the speed increasing gear box 2 by the knob 4. , the rotation of the cable drum 6 causes the disk 14 of the eddy current brake section to rotate via the speed increasing gear box 2. Furthermore, after manually turning and removing the knob 4 that connects the cable drum 6 directly to the input shaft 15 of the speed increasing gear box 2, the cable drum 5 can be easily replaced with another cartridge type cable drum. configured to be able to do so.

The case 5 covers the cable drum 3 and has a grip on its outer periphery that supports the body for the safety of the person during descent.
and a suspension row 128 are provided.

(Operation of the embodiment) Next, the operation of the wooden embodiment will be explained. There's a fire right now7.
When a person stranded in a high place of a building descends using the pre-equipped descending device on the Kinomoto side, the hook 25 is fixed to the building, the body is fixed to the hanging row 128, and the person is grabbed. Grab your stick and start descending.

When the descent is started, the cable drum 6 rotates, and the rotation is input to the input shaft 15 of the speed increasing gear box 2. When the rotation axis of the cable drum 3 is transmitted to the speed-increasing gear box 2, the final stage of the gears constituting the speed-increasing gear M2 rotates the disc 14 at an increased rotation speed tl. Since the disk 14 rotates in the magnetic circuit 16 shown in FIG.
A braking force is generated in the direction opposite to the direction of rotation of the disc 14.
limit the rotation speed of.

By turning the brake adjustment knob 21, the yoke B1
2 and the disk 14 changes, causing the disk 1
4, the braking force due to the eddy current changes. When descending, the person can be safely descended by setting the brake adjustment knob 21 to a position that matches the body of the person descending. share good luck.

After the first descent is completed, the person who will be descending next unscrews the knob 4 by hand, removes the cable drum 5, and then attaches a spare cartridge/Fuji type cable drum 3. can be done many times.

Next, other 181 of the present invention! An example will be explained.

In this embodiment, the hook 25 and hanging lobe 28 on the @8 real male side shown in FIG. 1 are installed in reverse.

By attaching the hook 25 and the hanging lobe 28 in the opposite direction, if the hook 25 falls during descent, the hook 25 will be identified to a building, etc., so the hanging gear @ unbody will not descend, but the hanging lobe 28 and the cable 26 will descend. . Therefore, the lowering device on the Kitsuyu side is used when lowering a person who is unable to move freely, and
It is effective in cases such as lifesaving.

(Effects of the Invention) According to the present invention, when a disk placed in a magnetic field is rotated by an external force, the eddy current flowing in the disk acts to brake the external force. By using a dynamically adjustable eddy-electric brake in the descending device, the descent speed of City 1 is automatically limited when descending from a height, making the descent easier and safer, as well as protecting the descending person. This has the effect of making it possible to adjust the descent speed limit according to body weight.
