In addition to the fields that manufacture and provide carry carts that can be used as trolleys and stretchers that enable elderly people and injured people to be transported manually, the equipment required for their transportation, storage, assembly, and installation, From the field of providing and selling instruments, the field of providing materials, machinery, and parts necessary for such materials, such as wood, stone, various fibers, plastics, various metal materials, etc. The field of parts and control-related equipment that integrates them, the field of various measuring instruments, the field of equipment, the power machinery that moves the equipment, the electricity that is the energy and the electricity that is the energy source Fields generally referred to as industrial machinery, such as the field of oil, as well as testing and researching those facilities and instruments, fields related to their display, sales, import and export, generals, and their use In addition to the results, the equipment used to build them, the fields related to the collection and transportation of garbage debris generated by the operation of equipment, and the recycling field where these waste debris can be reused efficiently, new ones that cannot be envisaged at this time There are so many unrelated technical fields.

(Points of interest)
In Japan, with the rapid aging of the population, the number of elderly people who have to go out on a daily basis for daily shopping is increasing nationwide. In addition, various circumstances such as the development of large-scale suburban commercial facilities have overlapped, and the distance from homes to fresh food stores such as supermarkets has been increasing, and the so-called “shopping weak” has been steadily increasing. .
In this way, people who have become “shopping weak” have to walk to the supermarket, bring heavy purchases such as daily grocery and household goods, and take a heavy physical burden. However, as a means to alleviate such a burden, many related products have spread to the market as a wheelbarrow with a loading platform and a shopping cart are very useful.

    On the other hand, how to safely and quickly accuse elderly people and people with disabilities living in areas close to the coastline in the event of a disaster such as a tsunami that must be accused of walking long distances There is a problem that accusing using automobiles has the disadvantage that it causes traffic congestion and delays accusing, and it is necessary to consider purchasing a wheelchair only for emergency evacuation, and a new economy The actual situation is that it has to be burdensome.

(Conventional technology)
Reflecting this situation, proposals that can be used to overcome this situation are not unheard of.
For example, as typified by what is proposed in Patent Document 1 (1) below, it can be used as a normal seat chair, and can be used by a wheel at the rear of the seat and a grip at the top of the backrest. The folding chair is integrated into one end of the stretcher, as shown in the patent document 1 (2) and the patent document 1 (3), and transported with the patient. As shown in the patent document (4), a stretcher or the like in which a suitable position of a wheelchair can be detachably connected to one end and can be pushed and pulled by one person is sometimes seen.

However, the seat mounted with a wheel as shown in the former patent document 1 (1) is advantageous for transporting indoors, but is not suitable for outdoor transport. Yes, one that incorporates a folding chair at one end of the stretcher as in Patent Documents 1 (2) and 1 (3), and the wheelchair can be connected to one end of the stretcher as in the latter Patent Document 1 (4) Goods are effective in preparing hospitals and nursing care facilities that require stretchers and stretchers, but in order to prepare them for ordinary households, they require a narrow range of use and a large and wide storage space. Therefore, there was a fatal defect that it was not practical.
