Generally, a "safety belt" is used to ensure the safety of workers engaged in aerial work during work. As described in the above-mentioned prior art, for example, a firefighter during firefighting activities may carry an air respirator on his back. Therefore, as a safety belt, a body belt type safety belt connected to the body of the firefighter is usually used. Is used.

However, for example, if a firefighter accidentally falls from a high place and becomes suspended during work, the firefighter will be in a state where his waist is bent in a dogleg shape when wearing the above-mentioned torso belt type safety belt. Therefore, a large traction load is applied to the waist and torso. Especially when wearing a respiratory organ, the weight of the respiratory organ is additionally added to the upper body of the firefighter, and the impact applied to the bent waist when the falling motion is stopped and the person is suspended in the air becomes considerably large. Furthermore, if it takes a long time to lift and rescue from the suspended state, firefighters will be injured, for example, by visceral damage due to the action of a large traction load due to the heavy weight of the respiratory organs and fire protection clothing. There is also a risk of suffering.

It should be noted that other workers who may carry out activities with their respiratory organs on their backs, such as mountain rescue workers, SDF personnel, police officers, and other special workers, have similar problems.

An object of the present invention is to provide a worker holder capable of reducing the physical burden on a worker who is suspended by carrying a respiratory organ on his / her back.

In order to achieve the above object, the present invention is provided on a backpack plate which is carried on the back of a worker and a respiratory organ is attached to the anti-worker side, and a lifting tool which is provided on the upper part of the backpack plate and can be engaged with the lifting tool. A pair of left and right leg belts, one end of which is attached to the left and right thighs of the worker and the other end of which can be connected to the left and right lower ends of the backpack plate, respectively. One end side is connected to the upper part of the backpack plate, and the other end side is connected to the lower part of the backpack plate after being passed over the shoulder of the worker through the chest side of the worker and under the armpit of the worker. A pair of left and right back straps and a second engagement part on which the lifting tool can be engaged are provided on one end side, and the other end can be connected to the left and right lower ends of the backpack plate, respectively. It is characterized by having a thoracoabdominal belt portion in which an intermediate portion between the one end side and the other end side is connected to the back carrying strap portion.

The worker holder of the present invention has a backpack plate having a first engaging portion on the upper portion and to which a respirator is attached, and a pair of left and right leg belt portions. One end of each leg belt is attached to the thigh of the worker, and the other end can be connected to the lower end of the backpack plate. As a result, by performing the work at a high place with the leg belt part connected to the backpack plate in advance, the traction load applied when the worker is suspended (or lifted for rescue) is first. It can act on the left and right thighs of the worker by the route of the engaging part → the upper part of the backpack plate → the left / right lower end part of the backpack plate → the left / right leg belt part. As a result, the worker is in a state where the back-carrying plate is hung from the back side together with the back-carrying plate (hereinafter, this state is appropriately referred to as a "rear-hanging state"), and also in the thigh by the above route. It will be in a suspended state. As a result, in the post-suspended state, the worker can be maintained in a stable and safe state in a posture as close as possible to the upright state, and the physical burden on the worker can be greatly reduced. In particular, it is possible to prevent the risk of refraction of the lumbar region and injury as in the case of using a body belt type safety belt.

According to the present invention, it is possible to reduce the physical burden on the operator who is in a state of being suspended by carrying the respiratory organ on his back.
