Description

Evacuation ladder with bed guiding mechanism

This creation is related to an evacuation ladder with a guiding mechanism for hospital beds, especially a building with floor guide rails on the floor of a building for the beds to lead to the entrance of the evacuation ladder, and the supporting surface of the carrier of the evacuation ladder The four casters of the hospital bed are used as a guide and a second guide groove, so that the hospital bed can be quickly pushed into the evacuation ladder for escape.

According to the fact that the current cities where humans live are already narrow and densely populated and land prices are becoming increasingly expensive, high-rise buildings on urban floors are extremely common. According to the current fire regulations, high-rise buildings must also have safety-related escape equipment. As a benchmark, there will always be building fire accidents in China where there is no rush to escape from the building and cause heavy casualties. The main cause of serious deaths and injuries is mostly inadequate escape measures; except for the failure of thorough public safety inspections In addition to implementation, the building’s own lack of escape measures is also unavoidable. If a fire accident occurred in the Carnival Building in Chiayi City, some of the victims were killed by jumping off the building in a hurry because they were unable to escape. How to deal with various unexpected disasters such as : In the event of unwarned disasters such as fires and earthquakes, the escape of lodging personnel living on high floors is obviously something that the residents of the building should take seriously. In the current general high-rise building escape equipment, the most commonly used are rope-type vertical landing equipment and escape ladders. The rope-type vertical landing equipment is often difficult to operate and shakes when climbing. Dare to try, and not everyone can apply, these devices are especially for the elderly It is even more difficult for patients, patients, people with mobility impairments, and children to provide quick and safe escape protection; in fact, most people have no experience in using this type of rappelling escape device, and they cannot be activated immediately in emergencies. Under the circumstances, most people do not dare to descend directly into the sky, and fall accidents due to improper operation may also occur.

Moreover, everyone knows that fire and water are ruthless, especially the occurrence of fires in buildings. When a fire occurs, in addition to fatal crises such as flames and dense smoke, the darkness generated after the loss of power is an obstacle to escape. A big killer, and when power is lost, the elevator that can quickly take people away from the fire is useless. In view of this, general fire escape equipment must comply with the principle that no electricity can be used. Therefore, there are no electricity escape equipment such as escape descent pipes (rescue bags) and descending machines. The regulator, in order to achieve the effect of emergency escape, has the same principle as the ancient pulley-type ancient well. It uses a pulley device and a centrifugal brake to control the descent speed. The equipment cost is low, but its operation is more complicated. When operating, personnel must hang and slow down outside the outer walls of high-rise buildings. When personnel are directly exposed to extremely high environments, they are easily affected by height fear and cannot be carried out. Operation, on the other hand, the operating procedures and formulas are too complicated. If it is not easy to operate by non-trained persons (such as firefighters), and its personnel escape efficiency is low (only for one person to operate), the effect of use is not obvious.

In view of the above, the structure of the rescue bag for the escape equipment is the simplest. It is fastened in a high-tensile cloth tube and installed in an appropriate position with a funnel-shaped ring belt with elastic effect. The ring belt has a slow-down effect so that personnel can quickly Drilling from the top of the pipe to slide to the bottom of the pipe to escape. Although the escape efficiency is higher than that of the slow-descent machine, the difference in descending speed caused by the size and motor nerves of the often restricted escapers may cause collisions between the escapees. On the other hand, if the pipe installation position is far away When the wall is too close, people may hit the wall and be injured. It is difficult for escapers with mobility difficulties to use rescue bags to escape, so there are still shortcomings in the use of rescue bags.

Please refer to the invention patent of the "Emergency Self-Propelled Evacuation Ladder Structure" of the Republic of China Announcement No. I652092, which discloses an evacuation ladder for personnel to escape. However, the area of its bearing seat is too small, and each bearing seat can be used. The number of escaped personnel is about a few, or an escape for a wheelchair person and a wheelchair person. Therefore, it is impossible for bedridden patients to use this kind of evacuation ladder to escape. In order to avoid such regrets, this creation is an evacuation ladder designed for bedridden patients, which can effectively help them to escape.

Therefore, in view of the above-mentioned problems and deficiencies, the creators collected relevant information, and through multiple evaluations and considerations, they began to design the creation of such an evacuation ladder with a bed guiding mechanism.
