Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a rescue bag used for evacuation between upper and lower floors in the event of a fire or other emergency.

[Conventional technology]

Most of the conventional ones were long enough to hang down a tubular evacuation rescue bag toward the lower floor when a fire broke out, and most of them had no special consideration.

[Problems to be solved by the device]

As mentioned above, in the case of the conventional one, the evacuees who are embarrassed when the fire breaks down and the bag is shaken, tilted, and twisted and deformed so that a smooth descent cannot be performed, and when the descent falls, the narrow balcony of the building, etc. There was a risk of injury by touching the body with the wall, handrails, or the protruding part such as the lower lid when hanging down.

[Means for Solving the Problems]

When the rescue bag was hung down, a required strong cloth or synthetic resin stool was placed at a certain distance below the upper end of the rescue bag to measure the posture and mental stability of the descendant. The evacuated and evacuated refugee was also allowed to step down on the stool provided a little below the upper end of the opening of the rescue bag, sit down, stabilize the posture, and then descend, so that unreasonable deformation stress is also applied to the rescue bag. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. In the floor 1 ', a hole penetrating between the upper floor 1 and the lower floor 2 is provided, and A through-hole frame A is fitted into the frame body A, and an upper lid 3 pivotally attached at one end through a hinge 11 is provided on the upper part of the frame A so as to be openable and closable.
In the lower part of the hinge, a lower lid 4 pivotally attached at one end via a hinge or the like is provided at the lower position of the hinge so as to be openable and closable, and a handle 13 is attached to the end of the upper lid 3 on the opposite side of the hinge 11. A horizontal locking ring 17 is fixed to the inner surface of the lower lid 4 on the side opposite to the hinge 12, and 5 has one end pivotally attached to the back surface of the upper lid 3 and the other end pivotally attached to the frame A to make the upper lid 3 The locking rod 14 for holding the opened state at the time of opening the lid, the gripping rod provided on the rear surface of the upper lid can be used to hang the safety rope 16 for gripping. Further, a lower lid releasing device B is provided on one inner surface of the frame A opposite to the hinges 11 and 12 side. The lower lid releasing device B has a grip portion 18 at the upper end and a lower end. The locking lever provided with a hook 21 on the lower lid 4 is configured to rotate freely with respect to the locking ring of the lower lid 4. Reference numeral 20 is a rotation shaft of the lever 19 and one end thereof is inserted through the lever 19. And is fixed to the inner surface of the frame body A.

Next, C is a tubular rescue bag, the upper end of which is wrapped with a bag mounting frame 6 and downward hooks are formed on the outer sides of the extension of each of the two parallel sides of the mounting frame 6. -Shaped support rod 10 is provided so as to project from the support rod.
Reference numeral 10 is configured to be engageable with and disengageable from an engagement ring 9 fixed to an inner side surface below the upper edge of the frame body A. The hook-shaped support rod 10 is inserted into and engaged with the engagement ring 9 to rescue the rescue ring. The bag C is suspended from the frame body A. Then, the evacuee sits down on the floor 1'of the upper floor 1 and lowers his foot into the opening of the rescue bag for the evacuee, which is located slightly below this floor, and the lower position of the rescue bag where this foot can easily reach In addition, the rescue bag is made of polyester and other suitable strong and flexible cloth at the horizontal position in the rescue bag formed by the inner surface of the rescue bag on the entry side of the evacuee and the pair of left and right inner surfaces of the rescue bag. The stool 7 having a required size is strongly sewn to the exterior body portion 8 of the rescue bag C. The evacuee once descends on the stool piece 7 and sits down to correct the posture, and then the descent opening D It is configured to descend more. A reinforcing belt may be sewn around the periphery of the seat-shaped piece 7.
Reference numeral 22 denotes a spreading member that supports the body of the rescue bag, 23 is a spiral descent cloth on which an evacuee descends, 24 is a lower exit of the rescue bag, and 25 is a bottom protection cloth.

The present invention is constructed as described above, and the rescue bag C is provided with the hook-shaped support rod 10 in the engagement ring 9 in the frame A when not in use.
By being engaged with the frame A, the hook 21 at the tip of the locking lever 19 is engaged with the locking ring 17 and folded on the inner surface of the closed lower lid 4 to be placed and stored. The locking rod 5 is bent and accommodated in the frame A, and the upper lid 3 covers the upper surface of the hole of the floor 1 '.

When using due to a fire or the like, the evacuee lifts the handle 13 of the upper lid 3 as shown in FIG. 5, and the upper lid 3 is easily opened by the hinge 11 and further opened by the locking rod 5. Held in.

Next, the evacuee turns the grip 18 of the locking lever 19 after confirming the safety status of the lower floor 2, and the hook 21 is disengaged from the locking ring 17, so that the lower lid 4 is hung down at the same time. The rescue bag C placed on the inner surface of 4 is automatically lowered and spread on the floor of the lower floor, and the evacuee holds the gripping rod 14 or the safety rope 16 and sits down on the floor 1 ', and rests his / her feet. After getting on one side and sitting down, the posture is corrected, and it is possible to get down from the descent opening for deposition, so that it is possible to take a descent action in a mentally and physically stable state.

Although the stool-shaped piece 7 is used as a stool itself as described above, it may be used as a suitable stool to adjust the posture of the evacuee.

[Effect of device]

That is, since the present invention is configured as described above, the evacuation person is less likely to sway or deform the rescue bag at the time of descent, and the descent start position is at least 25 m lower than the mounting position of the rescue bag. It will descend from the lower part of A, and it will be possible to evacuate normally, safely and reliably without contacting the lower lid hanging on the wall surface, fence, etc., and it will be effective to achieve the intended purpose. It is a thing.

Although the embodiment of the present invention shows a two-stage upper and lower lid releasing device in which an evacuee opens the upper lid and then rotates the locking lever to open the lower lid, the present invention is not limited to this. It is also applied to the case of the lid interlocking simultaneous release device.
