JPH1099462A - Clearance expanding machine for rescue of person from collapsed house - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an expanding machine which generates a good gap for lifting a collapsed part of a house for the purpose of rescue of person(s) living under the collapsed house. SOLUTION: A plurality of expansion devices 3 are furnished between a pair of upper and lower plates 2, and a power transmitting member 4 is installed to transmit the power required to expand each expansion device. The expansion devices may be operated mechanically or by fluid pressure. These are inserted to a gap in a collapsed house and expansion is made so that a good gap is produced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[Technical field to which the invention pertains] A lever used to rescue a survivor trapped in a house that has collapsed due to an earthquake or the like, and to extend the depth of a gap leading to the survivor.

2. Description of the Related Art Since fires and aftershocks, which are expected to occur after an earthquake, must be rescued as soon as possible, pillars and the like are used to enlarge the gap.

[Problems to be Solved by the Invention] It is difficult to extend the deep part of the gap by the method using the pillars and the like as levers.

[Means for Solving the Problems] In order to extend to the far side of the gap, an extension device is provided entirely up to the tip between two long levers as in the present invention, and a strong force is applied to the tip. If it can be extended to, it is possible to solve the problem.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, the present invention is extended to several places between a tip (1) between two long levers (2) and (7) to a root operating part (5). A device (3) is provided and the expansion device (3) and the operating part (5) are connected by a power transmission tube (or rod) (4).
The operating unit (5) is provided with an operating handle (6).

[Embodiment] 1. It is convenient to move the present invention if it is structured to be mounted on wheels. 2. The operation method such as expansion and contraction of the present invention is manual, electric,
Various methods such as hydraulic pressure can be adopted, and the operation is solid if two or more types are combined. 3. Combined use of compressed gas is also good to increase the efficiency of operation. 4. The present invention can also be used by being incorporated in an automobile. 5. The operation of the present invention can utilize an engine of a vehicle or a load power source.

[Effects of the Invention] Survivors who are trapped in a house that has collapsed due to an earthquake or the like must be rescued as soon as possible by the time of the next expected fire or aftershocks. The present invention can quickly and powerfully extend the depth of the gap leading to the survivor, and if the present invention is used on a wheel, movement and operation can be performed with only one person. Because it is possible, it is effective for rescue in case of urgent need.
