Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stretcher for carrying a victim.

[0002]

[Prior art]

 A stretcher, which is mounted on an ambulance or the like and carries a sudden sick person or an injured person, is generally composed of a rectangular frame body and a canvas stretched over the frame body. The frame body is formed by a double frame including an outer frame and an inner frame formed by bending an iron shaft, and the canvas is stretched over the inner frame.

In addition, a plurality of support legs are provided on both sides of the outer frame along the longitudinal direction, and a hanging metal fitting is provided. Further, both ends in the longitudinal direction of the outer frame project outward from the inner frame and are formed as handles.

Therefore, when the stretcher is placed on the floor or the ground, the support legs cause the frame and the handle to float a few cm above the floor or the ground, so that a victim can be placed on the handle and the handle can be carried by fingers. it can.

[0005]

[Problems to be solved by the device]

 By the way, a stretcher is used to carry a victim, and it is desirable that the stretcher be lightweight.However, as described above, the structure in which the frame body is formed by bending the iron shaft is heavy, In addition, the frame (usually 1850 mm x 550 mm) is integrated, making it inconvenient to carry and store when not in use.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a stretcher which is lightweight and excellent in strength and which can be folded and carried and stored when not in use. It is in.

[0007]

[Means and Actions for Solving the Problems]

 In order to achieve the above-mentioned object, this invention uses a hinge mechanism to rotate two substantially U-shaped frame components made of pipes with an inner layer made of a thin-walled metal tube and a fiber-reinforced synthetic resin-based composite material as an outer layer. It is characterized in that it is movably connected to form a rectangular frame body that can be folded in two, to which canvas is stretched, and a plurality of handles are provided.

The frame is lightweight because it is formed of a pipe with an inner layer made of a thin-walled metal tube and a fiber-reinforced synthetic resin-based composite material as an outer layer, and when not in use, the hinge mechanism is used as a fulcrum to support the frame. It can be folded in two, and the frame can be formed in half the size, so you can carry it with the handle.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 6, reference numeral 1 denotes a frame body, and the frame body 1 is formed by two substantially U-shaped frame component members 1a and 1b. The frame-constituting members 1a and 1b are formed by a pipe having an inner layer 2 made of a thin metal tube and an outer layer 3 made of a fiber-reinforced synthetic resin composite material.

The inner layer 2 of the pipe is, for example, an aluminum tube having an inner diameter of 23φ and an outer diameter of 25φ, and the outer layer 3 has, for example, an inner side as a GFRP layer 3 a as a second moment of inertia increasing layer and an outer side as a main reinforcing layer. It is formed on the CFRP layer 3b. The GF RP layer 3a is formed to have an inner diameter of 25φ and an outer diameter of 33φ, and the CFRP layer 3b is formed to have an inner diameter of 33φ and an outer diameter of 37φ.

The frame components 1a and 1b are connected at their end portions by hinge mechanisms 4 and 4 formed of a metal such as SUS. The hinge mechanism 4 is composed of a pair of rotating metal fittings 6 and 6 rotatably supported by a pivot shaft 5, and pipes 7 and 7 fixed to the rotating metal fittings 6 and 6. The tubular bodies 7, 7 are fitted to the ends of the frame constituent members 1a, 1b. Therefore, the pair of frame constituent members 1a and 1b are rotatably connected by the hinge mechanisms 4 and 4 to form a rectangular frame body 1. The frame body 1 has a pivot shaft 5 as a center. It is configured to be folded in one.

Support legs 8 and 8 are provided on the lower surfaces of the left and right sides of the frame body 1 so as to be spaced apart from each other so that the frame body 1 floats about 30 mm from the floor surface or the ground when placed on the floor surface or the ground. The fingers of rescue workers can be inserted into the lower surface of the frame 1. Further, the supporting legs 8 and 8 are arranged so as to be displaced in the longitudinal direction of the frame body 1 so as not to interfere with each other when the frame body 1 is folded in two.

A plurality of hanging metal fittings 9 ... Are attached to the upper portions of the left and right side portions of the frame body 1 at predetermined intervals, and the hanging metal fittings are located in the longitudinal middle portion of the frame body 1. A handle 10 is provided on the outside of 9. The handle 10 has a shape in which a metal rod is bent in a U shape and both legs thereof are bent outward, and the bent portions 10 a and 10 a are bound to the frame body 1 by a binding band 11.

Further, a canvas 12 is stretched over the opening of the frame 1 so as to close it. The canvas 12 is formed of a material having excellent strength such as a synthetic fiber sheet. The outer peripheral edge portion of the canvas 12 is wound so as to wrap the frame body 1, and the edges facing each other are placed on the back side of the frame body 1. It is stretched by connecting it with a synthetic resin string with excellent tensile strength. Further, notches 13 are provided in the canvas 12 at the four corners 14 of the frame 1, the hinge mechanism 4, the hanging metal fitting 9, and the handle 10.

In the stretcher thus configured, the victim is placed on the upper surface of the canvas 12 surrounded by the frame body 1, and the rescue workers have the four corners 14 ... Can be carried to a place. When not in use, the hinges 4 and 4 are used as fulcrums to fold the frame 1 in two, and the hanging metal fitting 9 is hung on a hook or the like, so that it can be compactly stored even in a narrow space such as an ambulance. Also, when carrying a stretcher, by folding the frame body 1 in two and raising the handle 10 to the top, the width dimension becomes 1/2, so that it is easy to carry.

In the above embodiment, the inner layer 2 of the pipe constituting the frame constituting members 1a and 1b is made of an aluminum tube, and the outer layer 3 is made of the GFRP layer 3a and the CFRP layer 3b. The present invention is not limited to the above embodiment, but may be composed of an inner layer 2 made of another thin metal tube and an outer layer 3 made of a fiber-reinforced synthetic resin-based composite material.

[0017]

[Effect of device]

 As described above, according to the present invention, two substantially U-shaped frame components made of pipes are rotated by a hinge mechanism with an inner layer made of a thin metal tube and a fiber-reinforced composite material of a synthetic resin type as an outer layer. It is movably connected to form a rectangular frame that can be folded in two, and by stretching canvas on this frame, it is lightweight, yet has excellent strength, and can be folded when not in use. The effect is that it can be carried and stored.

Moreover, since the second moment of area can be increased by using the composite material, the weight can be reduced by 30% or more as compared with the stretcher using the conventional iron frame body, and the canvas The area can be increased by 10% or more compared with the conventional double frame, and it has the effect of being able to accommodate the physique of human beings, which tends to increase year by year.
