2. Description of the Related Art Escape from the ground floor of a mandatory veranda is the worst in escape efficiency, and is a method impossible for a disabled person. Gondolas, etc. cannot be used from an unenclosed high-rise building with anxiety and the required area cannot be obtained. In addition, when a plurality of baskets are continuously formed, there is no method for suppressing variation in load. Indoor elevators are costly to provide for private power generation in the event of a power outage, are not continuous, and cannot be used at the discretion of each person in an emergency. In addition, the function is obligatory for indoor use because of the chimney phenomenon, but there is no example used.

SUMMARY OF THE INVENTION In the present invention, there is a drawback in providing an evacuation staircase outdoors, regardless of the cost in recent years, especially in the case where a turning staircase has been used. This unutilized central steel pipe section is expanded for safety, and an escape disk with an appropriate area is attached and detached so that it can descend continuously by its own weight, making it difficult for people who can not walk on stairs etc. It is intended for use. When utilizing the rigidity of the parallel folding stairs, expand the rectangular space in the gap of the stairs that is not used as well, install this device on the left and right sides, one for the descending one to return to the top of the escape disk If it is used, continuous circulation can be performed, which is more effective. That is, in the case of a single staircase around the former, an appropriate number of escape boards are stored in advance on the top floor, and a space for receiving the escape board is provided on the bottom floor, or the bottom is cut short to make it larger. It must be of a type that has a part that can be connected to the section of the steel pipe and that can be removed by each person. These proposals cover cases depending on the budget, building structure, and circumstances of the building space. In any case, the wheelchair area is intended for elderly people with disabilities, and it is difficult to consider legally because there is no conventional method. Trying to solve part. In fact, every time a high-rise building is created, the municipality is obliged to prepare a fire truck with a high-rise ladder, but the problems of modern budgets and imperfect functions are problems. To explain the basic structure of the present invention, as described above, the central steel pipe part having the building strength of the turning stairs is directly attached to a large-diameter steel pipe on a cylinder of an appropriate diameter, or an inscribed circle of the same diameter is formed. Attach the round stairs to the four vertical pillars to eliminate the non-utilized treads, and at the same time, provide an evacuation disk at the inner diameter, and properly fit the shield bearing in the vertical direction at the four-circumferential position inside the steel pipe. Attach at the screw pitch, but at that time, it shall be set as a female screw in the circumferential direction,
A short cylindrical disk set is set by inserting a male screw-shaped short cylinder that is screwed into the outer circumference with a rail provided on the outer circumference and screwed in. The disc is a wheelchair area escape board. On the disk, a non-rotating abutment plate is provided at the bearing position at the periphery of the disk to protrude to the bearing part, and the bearing is sandwiched.
It is also a function to prevent from the direction. In addition, it is equipped with an automatic braking device that holds the rotating shaft of the short cylinder when necessary, and an automatic governor device that keeps constant speed rotation, and furthermore has a sensor function to prevent danger when approaching each other. ,
It is designed to be as thin as possible so that it can be stored and stored in the upper part, and it can be operated electromagnetically so that the locking claws can be removed alternately. A projecting lever that stops at the calling position is provided. In the folding stairs, this cylindrical escape device is installed on the left and right, and the short cylindrical disk set is used for lowering one side and for restoring the other side, so that it can be circulated continuously. Or set up a small motor enough to raise the short cylinder set, rotate the short cylinder to raise, and when the short cylinder comes off the bearing on the top floor or the bottom floor, the sensor will work and move left and right respectively. However, the rotation axis of the short cylinder disk is slightly protruded above and below the short cylinder disk set, and a male screw is cut in that part, and it is attached to the female screw bush at the tip of the rotating arm provided on the top floor or the bottom floor. At the time of rotation and screwing in, the protrusion sensor on the bottom of the female screw bush worked, and the short cylinder disk was slightly raised on the top floor, and the magnet for lowering was activated on the bottom floor. , To motor swing arm may be adapted to transfer the short cylindrical rotated 180 degrees to the left or right may simply be used bushing mechanism. An automatic rotation system using an external power supply may be used, or a normal elevator system that operates the motor power supply by calling may be used. In the case of round stairs, in order to return to the upper part after use of the short cylindrical disk after accident treatment, set a small battery motor with enough torque on the disk to set up on the disk in advance and set it free on the shaft May be
Simply, an indoor ordinary elevator is used. This lifting mechanism can be the usual equipment of a fire engine if a single motor or a parallel mounting is used, and if a large motor is attached to a set of short cylindrical disks of the same type in some cases,
The extension cord of 0V power supply can be used for getting on and off firefighters for rescue. If it is possible to freely attach and detach the short cylinder disc set from the side including this case, it is convenient if it is possible to store an appropriate number of short cylinder disc sets on each floor and allow each person to freely attach and detach from that floor, In this case, of the four bearing pillars, one pillar facing the entrance is cut off at an appropriate size and detached from that part. For this purpose, at least the right and left ones of the contact plates provided in four directions are discs. Must be designed so that it can be manually moved in the direction of the center. The spring may be restored manually or automatically after loading. Since the cut portion of the pillar can be covered by three pillars, there is no problem in the lowering function. However, if all the supporting plates can be moved, the pillar can be removed without cutting. In any case, it is more convenient to use a cam groove, a lever, etc., and to use a spring to restore it with one touch in an emergency. In order to prevent this, two examples are shown in the embodiment instead of ultrasonic waves, lasers and the like, but at low cost. Further, for controlling the rotation of the short cylinder, the ordinary governor has a large volume mass and cannot be used. The present invention is implemented so that the standard rotation is maintained by the repulsive force of the floating permanent magnet and the fixed permanent magnet in order to perform the operation at a low cost and light weight.

[0004]

[Function] The large-diameter steel pipe in the center is indispensable as a pillar for the round staircase, and it is natural that the larger diameter is better if it becomes a high-rise building. With a small additional cost, the bearing-type drop mechanism requires no power and multiple escape stands can be dropped at the same time. In terms of safety, it is unlikely that multiple bearings will fall off. There is almost no need for maintenance and inspection with oil etc. because of the sealed bearing. It can be used for rescuing elderly people, children, physically handicapped, and those who cannot use stairs such as wheelchair users, and no measures are currently available. If there is an outer shell around the column periphery, there is also an advantage as fire protection. A disk and a set of short cylinders with one roll of rail wound at a pitch interval make it possible to store and store a plurality of thin and thin units. It is more efficient and effective to rotate the set of cylindrical disks. In that case, if the rectangular space of the folding stairs is expanded and used, it is convenient with low rigidity and low cost. In addition, because the risk of rear-end collision is performed by the approach prevention sensor,
There is no danger in getting on and off. Safety can be secured by using both automatic governor and manual brake braking. Healthy people can do it on the stairs, and disabled people have resolved to use this evacuation disk.
When a bearing is used, the cost of the bearing is negligible compared to the cost of building the surrounding stairs. In addition, it can be freely added to any height, and the cost is low due to unitization of factory production as a single set of rotating stairs, and the short cylindrical disk set itself is inexpensive if it is simple because it is cut once. A fixed and enclosed safety and a sense of security are inventions that have never existed before.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described by way of an embodiment. A cylinder 2 having a diameter of about 1 meter is constructed vertically in the center of the interior of a conventional round staircase 1, and the vertical columns 3.3 are formed at positions where the circumference thereof is divided into four equal parts.
, And the shield bearings 4, 4... Are mounted on the inner ring while maintaining an appropriate pitch, and are arranged in an appropriate female thread shape in the circumferential direction. A short cylinder 6 with one turn of a band iron 5 wound around a male screw
, And a disk 7 of substantially the same diameter is rotatably mounted on the center shaft of the short cylinder via a bearing 8.
In accordance with the position of the outer peripheral bearing on the peripheral surface of the disk 7, abutment plates 9, 9... The short cylinder 6 is rotated and dropped by its own weight according to the male and female screw lead angles. At this time, the disk 7 is prevented from rotating on the outer ring side surfaces of the abutment plates 9, 9,... And the bearings 4, 4,..., So that the disk 7 does not rotate, and supports the rotation runout of the short cylinder in the XY directions. The outer cylinder is made of fire-resistant material and the escape entrance is provided between the vertical bearing rows at appropriate positions. It is natural that the outer cylinder may be omitted and the pillar may be covered by four pillars. When the opening is provided on each floor, the pillar of that part is cut off at an appropriate size and if it is covered by the three parts, the width of the wider boarding area can be increased. Can also be secured. In this case, the center cam plate 1
By rotating 0 and moving in the axial direction, it is possible to store an appropriate number of short cylindrical disk sets on each floor and escape from each floor. In this case, if the spring K can be used for restoring, it can be loaded with one touch, which is convenient. The disk 9 has a double structure, and a space is provided between the disk 9 and the pad plate 9 and other components such as a braking device, a proximity prevention device, and a small motor for lifting. That is, the cylindrical evacuation mechanism of the same mechanism is installed on the left and right, and when the short cylinder comes off the bearing at the top floor and the bottom floor underground, the short cylinder disk set is moved left and right, and the short cylinder disk set It is effective to rotate between two units to make them endless. For this purpose, it is necessary to mount a small motor m with a clutch and brake on a disk and raise each of them. The female screw bush RR at the tip of the arm A provided at the shaft end of the upper and lower rotary motor devices SS has a vertically protruding male screw portion H of a short cylindrical disk set.
Is detected by the sensor J on the bottom surface of the female screw bush R at the time of screw connection, and the upper and lower electromagnetic magnets Q and
When the Q is operated and the set is slightly moved up or down, and then the rotating motor device S is rotated 180 degrees and then moves down, the clutch may be released, and in that case, the case moves up If the function is restored, the short cylindrical disk set with the number of bellies can be circulated and rotated between both units, which is more effective. The rotation motor may be a push mechanism. Next, as a consideration when a plurality of disks naturally fall, it is necessary to provide a proximity prevention sensor to avoid a rear-end collision. In the case of strong electric power, bare conduits D, D,... Cut at a distance twice as long as the proximity limit distance are provided along a plurality of rows of outer cylinders at shifted cutting positions s, s,.・ P and the magnet side pantograph or contact roller P ′ ・ P ′ are mounted on the disk side, and the bare conduit is fitted with a diode d at an appropriate short distance from the insulator h.
h is interposed in the pipe, the current is limited only in the upward direction, and a brake B of a type in which a short cylindrical shaft provided on the upper disk 7 is grasped only by a circuit from the battery power supply 11 provided on the lower disk. Is operated by the magnet M. The circuit diagram is shown in FIG. That is, the conduits D, D cut to the double of the proximity limit distance are set along the cylinder to the left and right with the cutting position s shifted by the proximity limit distance,
The contact rollers P, P, P ', P',... Are slid and the conduit D is further cut, and the diodes d, d,. Then, the circuit of the upper battery power supply including the own disk is cut off, and the brake magnet M operates when the lower battery power supply enters the proximity limit. Instead of this, a nested large and small steel pipe X with a structure that extends by an appropriate distance by natural fall is set to protect the electric wire circuit, and at the tip, a contact prevention sensor such as a reed switch Y working with a magnet, etc. What is necessary is just to perform with a self-disc battery power supply in a non-contact sensing system. Photovoltaic sensors, laser sensors, etc. all have large tolerances and are expensive, and the battery power consumption is severe. When using a motor for rotation, it is necessary to attach and switch a sensor for automatic selection up and down, but it is natural to provide a double row of diodes with different orientations. Alternatively, a coil spring may be provided. Also, a permanent magnet T of an appropriate length is provided on the disk 7 in the peripheral direction in order to make the rotation of the short cylinder constant by the governor mechanism, and the permanent magnet piece G is located at the appropriate position of the rotating short cylinder 6 at the center in normal rotation. Return spring k so that it moves to the circumference by increasing rotation
If the two magnets are installed so that they rebound in the event of excessive rotation, they can be covered by a lightweight and inexpensive governor device, and this device is considered to be a new and effective governor device in all general fields.

[0006]

According to the present invention, the installation cost is low, and a plurality of escape mechanisms which are impossible in the past can be made, and unlike the maintenance and inspection of ordinary elevators, oil application is not required because of sealed bearings, and there is an enclosure because there is an enclosure. There is no feeling of anxiety, and factory-installed products can be easily added depending on the degree of high rise.
