[Detailed Description of the Invention] The present invention aims to provide an evacuation device that allows people of all ages, men and women, sick people, physically disabled people, etc., to quickly and safely escape in the event of an emergency in a high-rise building such as a building fire. The purpose is

Buildings constructed in recent years are equipped with emergency stairs, evacuation ladders,
Evacuation equipment such as rescue bags has been installed, but there is a sense of anxiety in using these, and although they are useful for people who can move freely, they are not a very effective means of evacuation for the injured, sick, children, the elderly, women, etc. Nakatsuta.

This invention addresses the above-mentioned problems, and the gist of the invention is to suspend a boarding/disembarking case from a frame which is equipped with a braking function and has a drum around which a hanging wire is wound. In the braking mechanism, the drum and the braking wheel integrated with the drum are mounted around the horizontal axis of the upper part of the frame, one end is pivotally attached to the upper part of the frame, and the other end is free. A braking block for a brake lever, which is provided with a tension spring at the end to apply braking force, against which the peripheral surface of the brake wheel is pressed, and which is pivoted to the upper part of the frame so as to swing about the center as a fulcrum. A pushing piece fixed to one end of the interlocking lever is engaged with the free end of the brake lever against the force of a tension spring. The door is provided so that it can be opened and closed freely, and a foot-operated operating lever is attached to the bottom of the case, using the bottom inside of the back as a fulcrum, with the condition that its point of action is behind the center of the bottom of the case. In this structure, the braking mechanism and the boarding/exiting casing are swingably connected at the left and right ends of the lower part of the bifurcated frame to the central part of the upper side of the left and right side walls, with the door facing the front. At the same time, the point of action of the foot-operated operating lever and the other end of the interlocking lever of the braking mechanism section are connected by pivotal connection using a connecting rod, and a hanging wire wound around the drum is connected to the drum. The gist is an evacuation device characterized in that the evacuation device is pulled out through a guide cylinder that passes through the upper part of the frame, bypassing a guide roller supported by the lower part of the frame.

The present invention will be described below based on examples.

In the figure, reference numeral 1 is a boarding/disembarking case for evacuees to ride in.It has a height slightly lower than a person's height, is open at the top, and has a door 2 that can be freely opened at the front, which is completely open. installed. Further, an operating lever 15 is attached to the inner bottom of the boarding/disembarking case, with its fulcrum at the bottom of the inner surface of the rear surface and extending toward the front, with its operating point at the back of the center of the case.

A hanging frame 3 is attached to the upper part of the getting-on/off case 1, and a drum 5 around which a hanging wire 4 is wound is mounted on the frame 3 so as to be rotatable around a horizontal axis. The hanging frame 3 is made by vertically connecting a pair of large and small downward U-shaped band plates, with the left and right ends of the lower part 3a facing the outer surface of the upper center of the left and right side walls, with the door facing the front. is connected by pin 6.

The drum 5 is mounted on a shaft inside the U-shape of the upper part 3b of the frame 3.

The wire 4 pulled out from the drum 5
It bypasses the guide roller 7 on the lower side of the frame and is guided upward from the guide tube 8 of the upper frame portion 3b, and its upper end is engaged with a fixing member such as a hook (not shown).

A brake mechanism including a brake wheel 9, a brake lever 10, etc. is provided between the drum 5 and the frame 3. The brake wheel 9 is coaxial with the drum 5 and integrally connected to its side surface, and has a rough outer peripheral surface.

The upper end of the brake lever 10 is pivotally connected to the upper part 3b of the frame, and the brake block 1 is provided in the middle part.
1 is fixed to the brake wheel 9, and the braking block 11 is always pressed against the outer peripheral surface of the brake wheel 9 by the elasticity of a tension spring 12 stretched between the lower end and the frame 3.

Reference numeral 13 denotes an interlocking lever, whose middle part is pivotally connected to the frame 3, and a pushing piece 14 is fixedly attached to one end, and by swinging clockwise in FIG.
The pusher piece 14 pushes the brake lever 10 in the direction of releasing the brake. Interlocking lever 13
The other end and the point of action of the operating lever 15 provided at the inner bottom of the boarding/exiting case are connected by a connecting rod 16, and by stepping on the force point of the operating lever 15, the other end of the interlocking lever 13 is pulled down. and the interlocking lever 1
3 is adapted to swing counterclockwise in FIG. Along with this swinging, the pushing piece 14 at the tip of the interlocking lever 13 pushes the brake lever 10, so the brake lever 10 swings in the direction of releasing the brake against the biasing elasticity of the tension spring 12. The brake block 11 is separated from the brake guide wheel 9. As a result, the braking of the drum 5 is released and the drum 5 rotates in the direction in which the wire 4 is fed out, and the boarding case 1 is lowered in accordance with the length of the wire 4 fed out. When you want to stop the descent, all you have to do is take your foot off the operating lever 15, and the elasticity of the tension spring 12 will automatically push the braking block 11 against the braking wheel 9, applying braking to the drum 5 again. The feeding of the wire 4 is stopped.

As described above, in this invention, a drum on which a hanging wire is wound is mounted on the upper part of a boarding/exiting case, and this drum is equipped with a brake mechanism that constantly acts in the braking direction, and the drum is operated by operating a control lever. The system allows the evacuee to release the brakes on the evacuee, and simply by getting into the evacuee and operating the control lever, the entire casing will be lowered by its weight, making it easy and quick to lower the evacuee without much effort. You can evacuate from a high place to a safe low place. Therefore, regardless of whether the patient is sick or injured, young or old, men and women can easily escape to a safe area, and since their feet are always on the floor of the cage, they can use it without feeling anxious.

In addition, since the device does not require any power to operate, it will not be affected by accidents such as power outages and can be used without problems in emergencies.

In particular, in the device of the present invention, the interlocking lever and the brake lever are interlocked so that the pushing piece fixed to the interlocking lever moves the brake lever in the release direction at the free end of the brake lever. The resulting inclination of the casing in a certain direction, that is,
The tilt of the housing when the door is opened and weight is applied to the bottom of its entrance will cause the linking rod to move the end of the linking lever counterclockwise, which is in the same direction as the brake release direction. Since this is the opposite, the pushing piece is separated from the free end of the brake lever, the braking state is maintained, and there is no fear that the housing will start to fall inadvertently. In addition, even if your weight is applied to the back of the case from the center of the case when getting into the case, the point of action of the foot-operated control lever will be located further back from just below the pin connection position between the case and the frame. Since it is connected to the connecting rod, there is less error between the turning trajectory of the lower end of the connecting rod due to the inclination of the case around the pin connection point and the turning path of the lower end of the connecting rod around the fulcrum of the interlocking lever. This reduces the influence of the interlocking lever on the pushing piece. Therefore, even if you get into the back of the vehicle and the vehicle tilts, the brake will not be released, thereby increasing safety.

Furthermore, since the door for getting on and off is provided on the entire front surface, it is possible to get into the case extremely smoothly and quietly without making any dangerous movements such as climbing over the frame wall etc. and without shaking the case significantly. can. In other words, when climbing over a frame wall, etc.,
Shaking of the cage is caused by not being able to determine where the weight is applied on the bottom of the cage, and fear is caused by the height increasing by the frame wall or if the bottom of the cage is low relative to the boarding position. The feeling increases,
This makes people hesitate to get into the evacuation cage and becomes a hindrance to emergency evacuation. However, with the device of the present invention, where the entire front side is opened and a door is provided here so that the entry position and the bottom of the evacuation cage are horizontal, emergency evacuation due to fear etc. The factors that cause delays are eliminated.

Furthermore, the bifurcated suspension frame and the casing are pin-coupled at the center of the upper edges of the left and right side walls with the door facing the front, and an interlocking lever of the braking mechanism supported by the frame; Since the point of action of the foot-operated operating lever is connected to the point of action of the foot-operated lever mounted so that the point of action is located further back from the center of the case, the swinging movement of the case relative to the frame supporting the drum is restrained by the link. You can stabilize your upper body by grasping the bifurcated frame with your hands. Therefore, stability not only when boarding but also when descending is improved, the sense of fear during evacuation is significantly reduced, and smooth and quick evacuation becomes possible.

In addition, the hanging wire wound around the drum is pulled out through the guide cylinder that passes through the upper part of the frame, bypassing the guide roller supported by the lower part of the frame below the drum. The wire can be smoothly fed out, which has the effect of eliminating a stoppage caused by the wire stopping to feed out when the boarding/exiting casing is lowered.
