Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sloping stair lift for evacuation of vulnerable people in disasters.

[0002]

2. Description of the Related Art An evacuation stair is provided in an evacuation staircase enclosed by a fire-resistant structure wall in accordance with the Building Standards Law, and has a safe structure protected from fire and smoke during a fire. Therefore, in the event of a fire, it is the safest and safest evacuation method for people on higher floors to evacuate to lower floors via evacuation stairs, but vulnerable people such as the sick and elderly can walk on their own or Because it is difficult to go down the stairs, you cannot use the evacuation stairs to evacuate without some help. But,
No mechanical device has been developed to evacuate the vulnerable people to the lower floors using the evacuation stairs, and the fact is that they rely on human power from caregivers.

[0003] When a caregiver evacuates a vulnerable person via the evacuation stairs, at present, generally, two caregivers carry their arms together to carry the vulnerable person from both sides and drop it to the lower floor. However, this method requires two evacuees for each evacuee, and it is quite hard work for the evacuees to go down the stairs with the evacuees. There are limits to carrying many people.

In the case of a building on the second or third floor, there is a method of providing a slide on a balcony and evacuating by sliding down the slide. However, the balcony is not architecturally protected from fire and smoke. Being vulnerable to fire and high risk, the balconies are not directly connected to the corridors and require considerable effort to take them to the balconies,
Further, the balcony has a drawback that it is not easy to move laterally to the position of the slide because the width of the balcony is small or objects are placed on the balcony. Buildings with four or more floors cannot be evacuated on a slide because it is dangerous to slide down on the slide.

At present, there are various types of stair climbing devices for wheelchairs (Japanese Patent Application Laid-Open No. 9-58950 and Japanese Utility Model Application Laid-Open No. 63-142373). Most of them are of the system type, and there are various measures in the event that the device becomes unusable due to a power outage or the like, but in any case, there is still a problem in securing operation during a disaster. Furthermore, the current equipment is based on the use of lower floors, and it is considered difficult to accommodate the recently increasing middle and high rise facilities for the elderly.

[0006]

In short, this is an emergency evacuation facility used for evacuation stairs in a multi-story building, which does not rely on electric energy (electric power) or the like only in one direction of descending. Nothing to move is currently found. The present invention seeks to solve such a point and to provide a simple and safe one that can be used easily.

[0007]

To achieve the above object, according to the first aspect of the present invention, the guide rails 2 are sequentially provided from the upper layer to the lower layer on the back surface 19 of the evacuation stairs 1 in the evacuation staircase A. At the same time, a pull-in rail 3 connected to the guide rail 2 is arranged at various points to provide a stock yard 4, and the guide rail 2 is detachably engaged with the pull-in rail 3 and the guide rail 2 to guide the lower portion. Multiple descenders 5
These descenders 5 are provided with a traveling means 6 which engages with the guide rail 2 and an accumulator which obtains a bias for horizontal movement by mechanical energy accumulated with the descending movement by interlocking with the traveling means. And a lifting device 8 with a stopper, and a lowering device 5
An appropriate number is always provided on each of the pull-in rails 3 of each of the stock yards 4.

According to a second aspect of the present invention, there is provided the evacuation stairs lift for evacuation of the weak vulnerable in the first embodiment, wherein the stock yard 4 having the pull-in rails 3 is arranged in the evacuation staircase A on each floor. It is provided in a space other than the room floor 9 and the evacuation staircase A, and the energy storage device 7 serves as a mainspring, a flywheel, an air pressure accumulator, and other mechanical energy accumulators.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of the present invention in which a rectangular evacuation staircase is equipped with a sloping stair lift for evacuation of vulnerable persons. In the figure, 1 is a rectangular evacuation staircase in the evacuation staircase A of various concrete buildings, and 2 is
The guide rails 3 are attached to the evacuation stairs from the upper part to the lower part on the back surface 19 of the stairs on the second and higher floors. The pull-in rails 4, which are attached to the corners and the ceiling surface of each floor 11 other than the evacuation staircase A in connection with the guide rails 2, are stock yards formed with these pull-in rails. 10 is a landing in the evacuation staircase A. Reference numeral 5 denotes a plurality of descenders which are detachably engaged with the pull-in rails 3 and the guide rails 2 to guide and move downward.
In each case, a suitable number is provided on each of the pull-in rails 3.

The guide rail 2 is made of a metal material (for example, an aluminum material) as shown in FIG. 3 or the like. 3 and, specifically, as shown in FIG. 3, mounting hardware 12 is fixed to various places on the back surface 19 of the stairs, and projecting pieces are provided on these mounting hardware from various locations on the upper surface of the rail. 13 is attached by fastening with bolts and nuts 14. The same applies to each pull-in rail 3. Also, each pull-in rail 3 and guide rail 2
Although not shown, the connecting portion is normally urged to form a guide rail line, and
Side has a normal switching means for forcibly entering against the bias. Further, a rack gear 15 extends along the guide rail 2 and the pull-in rail 3 on the inner surface.

As shown in FIG. 3, the descender 5 is provided with a traveling means 6 which engages with the guide rail 2 and a mechanical movement which is mechanically interlocked with the traveling means and which is used for horizontal movement by mechanical energy accumulated with the descending movement. And a power storage device 7 for obtaining the bias of the above, and a manual lifting device 8 for a suspension rope with a stopper. The traveling means 6 has a wheel 17 to be engaged with the guide rail 2, the retracting rail 3, the connecting rail 11 and a pinion gear 18 to be meshed with the rack gear 15 on the descender body 16,
The pinion gear is mechanically connected to the energy storage device 7 in the descender body 16. As the energy storage device 7, a mainspring, a flywheel, an air pressure accumulator, and other mechanical energy accumulators are used. The number of these mechanical energy storage means is not limited to one, and it is needless to say that several mechanical energy storage means may be arranged side by side, and when they are arranged side by side, they can be operated all at once or sequentially. is there. The hanging rope manual hoisting device 8 with a stopper is a general hand-operated one and is mounted on the lower part of the descender body 16.

[0012] For example, when a vulnerable person in a wheelchair is evacuated from the second or more floors to the first floor (evacuation floor), the caregiver must use the stockyard on the floor 9 of the evacuation staircase room. 4 and pull out the suspending rope from the suspending rope manual hoisting device 8 with a stopper.
Hanging on a wheelchair or the like on which a vulnerable person such as the elderly rides, and manually lifting the hanging rope manual hoisting device 8 with the stopper, the wheelchair and the like are lifted together, and then the descender 5 is moved to the guide rail 2 (the inclined portion). Up to). Guide rail 2
The descending machine 5 sent downward moves the inclined portion of the guide rail 2 downward by the load of the wheelchair or the like on which the vulnerable person of the disaster rides and the weight of the descending machine 5, and at this time, the pinion gear 18 Mechanical energy is transmitted to the energy storage device 7,
It is stored in the energy storage device 7. At this time, the speed of the movement is moderately braked (1 m / sec) by using the energy storage device 7 as a load before there is no danger. In this way, when the descender 5 reaches the horizontal portion through the inclined portion of the guide rail 2, the mechanical energy stored in the energy storage device 7 is released in reverse here, and the descender 5 Self-propelled to the next inclined part using the power source as the power source, and the inclined part is moved downward again by its loading load and the own weight of the descending machine 5. Automatically descends to the floor (evacuation floor). After that, on the first floor (evacuation floor), the caregiver manually operates the hanging rope manual hoisting device 8 with the stopper of the descending machine 5 to lower the wheelchair or the like on which the vulnerable person is on the floor and evacuate. That is, it can function without using any electric energy or the like, and does not hinder a power failure or the like in the event of a disaster. The descending machine 5 after descending may be disengaged, lifted up to the upper floor again, and engaged with the rail at important points.

The descending machine 5 may be equipped with a rear-end collision preventing mechanism such as a nose for setting an interval in order to prevent a rear-end collision.
Further, the descending machine 5 may be equipped with a mechanical brake so that it can be stopped arbitrarily. The specific forms of the various rails and the traveling means 6 are not limited to those shown in FIG.

[0014]

According to the present invention, since the configuration is as described above,
In the descending machine 5 engaged with the pull-in rail 3 or the guide rail 2, the wheelchair or the like on which a sick person, an elderly person or the like, on which a vulnerable person such as a disaster is riding, can be easily lifted manually by the suspension rope manual hoisting device 8 with stopper. In addition, the descender 5 can automatically lower the inclined portion of the guide rail 2 by utilizing the mounted load and the own weight of the lowerer itself, and accumulate along with the lowering movement. Power device 7
Can store mechanical energy, and can be mechanically self-propelled to the next inclined portion by the stored mechanical energy during the subsequent movement in the horizontal portion. In the downward movement at the inclined portion, the mechanical energy is stored in the energy storage device 7 so that the lowering device 5 is moved.
Can be braked moderately, and can be moved down safely. Therefore, electric energy is unnecessary, and there is no possibility of being unusable due to a power outage or the like during a disaster, and operation can be secured safely as long as sufficient disaster countermeasures are taken in the evacuation staircase A of the building. It can be used safely in multi-story facilities for the elderly without any problems. In addition, a large number of vulnerable to disaster can be evacuated easily and easily by a small number of caregivers with little labor. Furthermore, since the evacuation stairs of the evacuation staircase A can be equipped with the evacuation stairs, even in the event of a disaster, the vulnerable people can safely evacuate using the evacuation stairs. In the yard 4, the required number of the drop-in rails 3 can be kept at a constant level, and when a disaster occurs, it can be quickly and appropriately adapted. In addition, the structure can be simplified, easily manufactured and provided at low cost.
