2. Description of the Related Art Conventionally, when carrying a tatami mat to an upper floor of a high-rise house, the tatami mat has generally been manually carried up to a predetermined floor. Further, in recent years, it has been seen that tatami mats are carried into the upper floors by using a crane truck or a lift truck.

[0003]

[Problems to be Solved by the Invention] However, when tatami mats are manually carried up to the upper floors of a high-rise house, it is necessary for a person to carry the tatami mats one by one up and down the stairs many times. The work was extremely heavy and the work efficiency was extremely poor. Even in a house with an elevator, there is a considerable distance for a person to carry a tatami mat (the distance from the position of the transport vehicle to the elevator and the distance from the elevator to the loading place), and transportation between them was difficult.

Further, when a tatami mat is carried in by using a crane truck or a lift truck, a large-scale mechanical device such as a crane truck is required (especially, a large model is required in the upper floors), resulting in equipment cost. In addition to being expensive, there is a problem that it cannot be used at a work site where a mobile crane or the like cannot be installed side by side. Also, especially when carrying a small amount of tatami,
Such a large mechanical device is not suitable.

In view of the above-mentioned conventional problems, the present invention is relatively light work and efficient when carrying in tatami mats to the upper floors (higher than 2 floors) of a high-rise house regardless of the number of floors (height) of unloading. It is an object of the present invention to provide a tatami hoisting device that can be carried in well and is small enough to be carried by a person (inexpensive) and can be used in a wide range of places.
