연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

An embodiment of the invention is directed to a system having a pulley attached to a building. A closed loop of cable is installed around the pulley. The loop is of sufficient length so as to reach, when deployed outside of the building, below the pulley to where emergency personnel gather in an area next to a base of the building (when responding to a disaster situation in the building). A winch around which the loop is to be operatively installed is located in the area next to the base. Other embodiments are also described and claimed.

What is claimed is: 1. A system comprising: a pulley permanently attached to a non-portable structure; a closed loop of cable installed around the pulley and being of sufficient length so as to reach, when deployed outside of the structure, below the pulley to an area next to a base of the structure; a load attached to the loop; a traction winch around which the loop is operatively installed to lift the attached load, the traction winch being located in the area next to the base; and a moveable pulley around which the loop is installed, the moveable pulley being located in the area next to the base and designed to be moved relative to the winch and said pulley to (i) increase tension in the loop as installed so that the load, suspended by the loop, moves away from a side of the structure and (ii) decrease tension in the loop as installed so that the suspended load moves towards the side of the structure. 2. The system of claim 1 wherein the structure is a building and the pulley is permanently attached to a structural support of the building located near an edge of a roof of the building. 3. The system of claim 2 wherein the winch is mounted on a vehicle and is designed to move relative to the vehicle and relative to said pulley to change tension in the loop as installed so as to move the load, suspended by the loop, towards and away from a side of the structure. 4. The system of claim 2 wherein the winch is mounted on a vehicle, and wherein the vehicle is to move horizontally in the area next to the base to adjust a horizontal distance between the load, while suspended by the loop, and a side of the structure. 5. The system of claim 1 wherein the winch is designed to be moved one of horizontally and vertically relative to the pulley to move the load, suspended by the loop, towards and away from a side of the structure. 6. The system of claim 1 wherein the winch is mounted on a vehicle. 7. The system of claim 1 further comprising means for automatically deploying the loop from a resting state in the structure. 8. The system of claim 1 wherein the load is attached to a near section of the loop and wherein a far section of the loop, when the loop has been deployed and installed on the traction winch, is positioned farther from a side of the structure than the near section. 9. The system of claim 8 wherein the traction winch uses power and braking to directly act upon the far section of the loop, wherein power is used to pull in the far section and thereby lift the load and braking is used to let out the far section to thereby lower the load. 10. The system of claim 8 further comprising a load stabilizing mechanism that includes: a guide cable attached to the structure and running along the side of the structure between the pulley and the base; a first guide line that is under tension and connects the guide cable to the load and can slide along the guide cable as the load is one of raised and lowered; and a second guide line that is under tension and connects the far section of the loop to the load and can slide along the far section as the load is one of raised and lowered. 11. The system of claim 8 comprising a further load attached to the far section of the loop and designed for carrying further equipment or personnel. 12. A system for raising firefighters and equipment to and evacuating people from an upper floor of a multistory building, the building having a roof, a base, and at least one upper floor, said system comprising: a bi-directional traction winch disposed at the base of the building to cooperate with a first pulley permanently mounted on the roof or an upper floor of the building and a closed loop of cable connected around said first pulley and said traction winch; a first container for holding at least one person connected to said loop of cable at the base of the building, so that (1) when said traction winch is activated in a first direction, said first container travels to the upper floor of the building, and (2) when said traction winch is activated in an opposite second direction, said first container travels to the base of the building; and a plurality of pulleys around which said loop is further connected, one or more of said plurality of pulleys being designed to be moveable under power and under control of an operator of the system, relative to the traction winch and the first pulley, to move the first container towards and away from a face of the building. 13. A system according to claim 12, further including: a second container connected to said loop of cable, said second container disposed on an opposite side of said loop of cable from said first container, so that (1) when said winch is activated in said first direction, said second container travels to the base of the building, and (2) when said winch is activated in said opposite second direction, said second container travels to the upper floor of the building. 14. A system according to claim 12, further including: means for moving said first pulley from a retracted position on the roof to an extended position wherein said first pulley hangs over an edge of the roof. 15. A system according to claim 12, further including: means for storing said loop of cable on the roof of the building prior to said loop of cable being connected around said winch. 16. A system according to claim 12, further including: means for storing said loop of cable next to a face of the building prior to said loop of cable being connected around said winch. 17. A system according to claim 12, wherein a plurality of selected positions along said loop are defined to which said first container is connectable.
