Description

[Detailed explanation of the invention] [Purpose of the invention] "Industrial application field" This invention relates to evacuation equipment used when evacuating from buildings of two or more stories in the event of a fire. This relates to evacuation equipment that allows safe evacuation.

``Problems to be solved by conventional techniques and ideas'' Conventionally, in high-story buildings, rope ladders, chutes, or ropes are installed inside the building for emergency purposes.
It is desirable to install a large number of these chutes and rope ladders, but it is expensive to install a large number of them, and in reality, unless you have a number close to the number of people that can be accommodated in the building, you will not be able to do it in time in an emergency. Despite this, the number of installations is small. Although it is easy to prepare a rope, descending using a rope requires skill and physical strength, and the descent can take a long time, and a steep descent can result in burns to the hands.

The purpose of this invention is to solve the above-mentioned problems of the prior art and provide an inexpensive and easy-to-use evacuation tool for evacuation from buildings with two or more floors.

[Structure of the idea]

``Means for solving the problem'' This idea has a drum equipped with a rope winding drum section and a braking section that is rotatably supported on the machine frame around a horizontal axis, and the braking section of this drum has a sliding force. The machine frame is equipped with a brake piece that is movably held toward the brake part of the drum, and the pulley is pivoted by a horizontal pulley shaft connected to the brake piece. This evacuation device is characterized by having its protruding side wrapped around a pulley and a rope extending from the pulley.

``Operation'' When the machine frame is held in the building and an evacuation target, for example a human body, is held at the end of the rope, the rope is pulled downward by the gravity acting on the human body, the pulley rotates, and the rope is wound around the winding section. A certain rope is let out and the drum rotates. At this time, at least the weight is applied to the pulley, so the pulley shaft that supports the pulley transmits force to the brake piece, and the brake piece presses the brake part of the drum, so the speed at which the rope is let out is limited. The human body reaches the ground at a moderate speed.

"Example" Hereinafter, an example of this invention will be described with reference to the drawings. FIG. 4 is a front view, and FIG. 2 is a side view of FIG. 1.

A horizontal drum shaft 2 is fixed to a machine frame 1 made of sheet metal. A drum 3 is rotatably fitted into the drum shaft 2, and the drum 3 is attached to the part 1 of the machine frame 1.
a and 1b to prevent it from moving in the axial direction. The drum 3 is a rope winding section 3 that winds the rope.
a, and a brake drum section 3b as a braking section. The machine frame 1 is provided with a brake piece 4 movable toward the brake drum portion 3b. The brake piece 4 has a brake piece part 4a that slides against the upper part of the brake drum part 3b serving as a brake part, and a vertical guide groove 1 of the machine frame 1.
c, 1c, and has a holding piece 4b so as to be allowed to move up and down. This holding piece portion 4b is not limited to this, but is movable so as to be able to press the brake piece portion 4a of the brake piece 4 against the brake drum portion 3b, and is also movable so as to be prevented from rotating together with the brake drum portion 3b. Any mechanism is sufficient.

A pulley shaft 5 is fixed to the holding piece 4b of the brake piece 4, which is perpendicular to the drum shaft 2 and located above the brake drum part 3b. The pulley shaft 5 is the holding piece 4
b, and is fitted into a long hole 6 in the vertical direction provided in the machine frame 1 so as to be vertically movable, so as not to interfere with the application of force of the brake piece 4 toward the brake drum portion 3b. It's getting old. The holding piece 4b of the brake piece is bifurcated, and the pulley 7 is fitted into the fork between them, and the pulley 7 is rotatably fitted into the pulley shaft 5.

One end of a rope 8 is fixedly wound around the rope winding portion 3a of the drum. and rope 8
A rope 8 let out from the rope winding part 3a is wound approximately 180 degrees above the pulley 7, and a human body holding means 9 is tied to the end of the rope 8 hanging down from the pulley 7.

In this embodiment, the human body holding means 9 is a handle 9a connected to the rope 8, but this part is a hanging basket tied to the rope 8 and suspended, or a two-tiered basket whose upper part is tied to the rope 8, or a handle 9a connected to the rope 8. It may be part of a ladder with several steps, or it may be a vehicle that can move vertically using the wall of the building as a moving surface, but is not limited to this.

Reference numeral 11 denotes a hanging ring attached to the upper part of the machine frame 1, and its position is selected so that the evacuation equipment can be hung in the posture shown in the figure.

In the above, the rope 8 is made of nylon fiber, for example, and is thin and strong, and has a diameter of about 3 to 4 m/m to support one human body.

Next, the effect will be explained. Normally, the hanging ring 11 is placed at an appropriate location in the building so that it can be hung in a usable condition, or it is installed inside the building and in case of an emergency, the hanging ring 11 is used to hang it outdoors, for example, under the eaves. Lower it.
Normally, the rope 8 is stored in the rope winding section 3a, wound up to the maximum extent possible, and the handle 9a of the human body holding means 9 is located near the pulley 7. In case of emergency, handle 9
When a person holds a in their hands and hangs it, one side of the pulley 7 is pulled in the direction of the cut line due to the gravity acting on the human body, and the part of the rope 8 facing the rope winding part 3a from the other side of the pulley 7 is pulled by the gravity acting on the human body. The rope 8 wound around the winding section 3a is pulled out in the direction of the cutting line, and the drum 3 is rotated on the drum shaft 2. Pulley 7 rotates on pulley shaft 5. The gravity acting on the human body applied to the handle 9a is applied to the pulley shaft 5 via the pulley 7, and the pulley shaft 5 pushes down the brake piece 4. The brake piece 4 is located in the guide groove 1c of the machine frame 1.
The brake piece part 4a moves slightly inside and presses the outer periphery of the brake drum part 3b of the drum. This results in
The speed at which the rope 8 is accelerated and pulled out by gravity acting on the human body is limited, and the human body can descend toward the ground at an appropriate speed.

Although the embodiment has been described with respect to a building, it goes without saying that it may also be used for transferring from a ship to a lifeboat in the event of a marine accident.

In the embodiment, the evacuation target is a person, but it may be an object or an animal.

Although the embodiment describes the case of vertical descent, it is also effective when descending on a steep slope.

[Effect of idea]

This idea consists of a drum equipped with a rope winding drum part and a braking part, which is rotatably supported on the machine frame around a horizontal axis, and which is equipped with a rope winding drum part and a braking part. The pulley is pivotally supported by a horizontal pulley shaft connected to the brake piece. Since the evacuation device is characterized by being provided with a stretched rope, when used in the event of a fire or other emergency in a building, etc., a person can quickly descend to a low place such as the ground at an appropriate speed. Since no special operations are required, evacuation can be started quickly in the event of an emergency. Since it is simple and inexpensive, the equipment cost is small even if it is installed in excess of the number of people the building can accommodate. It only supports the weight of the human body, and since it is small, it is unnoticeable even if it is hung under the eaves all the time.
