DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable stretcher provided with a sliding portion on a lower surface, which is used for carrying an injured person or the like at the bottom of a ship to an upper deck or the like.

[0002]

2. Description of the Related Art Conventionally, when an injured person or the like appears on the bottom of a ship or the like, conventionally, the injured person or the like is laid on a stretcher, and a person who carries out the injured person with the injured person lying on the stretcher. He lifted the stretcher with both ends, and moved and turned around on the narrow bottom of the ship as it was.

[0003] Further, in order to carry out the injured person or the like from the bottom of the ship to the upper deck, a steep ladder must be climbed. A person carrying injured persons was climbing up the ladder while holding the stretcher by the ends of the stretcher.

However, the bottom of the ship is very narrow, and the ladder leading to the upper deck is steep as described above, and the hatch is very narrow. It was not easy to move the ship's bottom with the ends of the stretcher, and then lift the ladder and carry the injured person to the upper deck.

[0005] In particular, when climbing a ladder or the like, the ladder was lifted while lifting a stretcher that was long,
It required considerable effort.

Further, it has been almost difficult to change the direction at the bottom of the ship with the injured person or the like on a stretcher.

Also, the stretcher needs a certain length so that an injured person or the like can be sufficiently laid down, but the stretcher used conventionally can adjust the entire length of the stretcher. However, since it could not be folded, when not in use, it was necessary to secure a sufficient storage space for the stretcher, which was inconvenient for storage.

Accordingly, the present invention is capable of easily moving an injured person or the like when the injured person comes out at the bottom of the ship or the like, easily changing the direction in the bottom of the ship, and using a steep ladder. The object is to provide a stretcher that requires a minimum amount of labor when climbing and that takes up little space for storage.

[0009]

The stretcher according to the present invention comprises a backrest, a seat foldably connected to the backrest 2, a front leg foldably connected to the seat, and one end. It consists of a sliding portion connected to the backrest portion and a rear leg portion foldably connected to the other end of the sliding portion, and adjusts the angle of the seat portion with respect to the backrest portion and the angle of the front leg portion with respect to the seat portion. Angle fixing means that can be fixed arbitrarily.

As described above, in the stretcher according to the present invention, the backrest portion and the seat portion are foldably connected, and the seat portion and the front leg portion are also foldably connected. Since it has angle fixing means capable of arbitrarily fixing the angle and the angle of the front leg portion with respect to the seat portion, when an injured person or the like occurs, the seat portion is bent with respect to the back portion and the chair type. Therefore, it is possible to move the ship bottom while the injured person or the like is sitting, and the injured person or the like can easily move and turn in the narrow ship bottom.

In addition, since the backrest has a sliding portion having one end connected thereto, even when climbing a steep ladder, the stretcher is lifted up by a rope or the like while sliding the sliding portion on the ladder. It became possible to lift the stretcher on the deck, and it became unnecessary to lift the stretcher, so that injured persons could be carried to the deck or the like with minimum effort.

Further, in the present invention, the rear leg is also connected to the sliding portion so as to be foldable, so that when the stretcher according to the present invention is folded, the storage space is not so much required.

Still further, the stretcher of the present invention has angle fixing means which can arbitrarily fix the angle of the seat with respect to the backrest and the angle of the front leg with respect to the seat. The angle and the angle of the front leg with respect to the seat can be arbitrarily fixed. Therefore, when leaving a narrow hatch, the angle of the seat with respect to the backrest should be reduced to reduce the distance between the sliding portion and the seat. This makes it possible to easily exit the narrow hatch.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION In a stretcher according to the present invention, a seat is connected to a backrest via a joint so as to be foldable, so that the seat can be bent and folded.

A front leg portion is also connected to the seat portion via a joint so as to be foldable, and the leg portion is also foldable and foldable.

Further, one end of a sliding portion is connected to the backrest portion, and a rear leg is connected to the other end of the sliding portion via a joint or the like so as to be foldable.
The rear legs can also be bent.

An angle fixing means is provided on the rear leg so that the angle of the seat with respect to the backrest and the angle of the front leg with respect to the seat can be arbitrarily fixed.

Therefore, when an injured person or the like occurs, the stretcher of the present invention is formed into a chair shape by bending the seat portion and fixing the angle with respect to the backrest portion. It is possible to sit and carry people etc.,
After the injured person or the like is carried out to the deck or the like, it is possible to release the bending of the seat portion, lay the injured person horizontally with respect to the backrest portion, and carry the injured person directly to an ambulance or the like.

Further, when raising the stretcher on which the injured person or the like is sitting on the upper deck, the runner may be lifted with a rope or the like while sliding on a ladder, as in the case of the conventional stretcher. Eliminates the need to lift the ladder while lifting the stretcher.

Further, when not in use, the seat, the front leg, and the rear leg can be folded down to be stored.
