３）が開示されている。BACKGROUND OF THE INVENTION Generally, a tandem connection of cars, as seen in trailers and trains,
Due to its good directional controllability, a system is adopted in which the preceding vehicle is driven and the rear vehicle is towed. However, if the front vehicle is pushed by hand when the wheelchair is connected in tandem, the connection device will interfere with the caregiver and the caregiver will be sandwiched between the two wheelchairs, which may affect the patient in the rear vehicle. The problem is that the caregiver cannot see what is happening. Further, as the invention of the prior application, for example, Japanese Patent Application Laid-Open No. 9-56750, “Method for transporting a wheelchair on which a patient rides on the road and a connector used in the method”

対応、軽量化、着脱の簡略化が難しい。In the conventional method 1, a wheelchair on which a patient rides is
It is a method of towing by a wheeled vehicle or a three-wheeled vehicle, and is not suitable for connecting two wheelchairs. The conventional method 2 is a method of connecting two wheelchairs side by side. Because the width is too wide, there are places where the width exceeds the width of doors, etc., and there is a place where it cannot enter, or it interferes with other passages in narrow passages. Prone. In the conventional method 3, since the front wheelchair and the rear wheelchair are connected by only one connecting rod that can be bent in the left, right, up, and down directions, the intention of operating the rear wheelchair is hard to be transmitted to the front wheelchair, and the straightness and direction control are difficult. There is. Further, since a beam that straddles the left and right frames of the wheelchair is required, it is difficult to flexibly cope with the dimensional disparity of commercially available wheelchairs, reduce weight, and simplify attachment / detachment.

（７）構造が簡単で軽く、非力な看護婦でも簡単に脱着
できる。According to the present invention, the following effects are exhibited. (1) The intention to operate the rear wheelchair can be reliably transmitted to the front wheelchair, and one caregiver can freely and easily move and operate the two wheelchairs in a desired direction while observing the state of the patient. (2) Since one caregiver can move two wheelchairs without requiring an unnatural posture or force, the caregiver's physical fatigue can be reduced. (3) Since the connecting device is not influenced by the frame width of the wheelchair, it is possible to flexibly deal with the dimensional difference of various commercially available wheelchairs. (4) In the shortage of caregivers in the medical field, it is possible to reduce the labor required for moving patients to the hospital and taking walks outdoors. (5) Patients will be able to receive sufficient services for in-hospital and outdoor walks. (6) Since the connecting device does not require a mounting jig such as a beam that straddles the left and right frames of the wheelchair, the connecting device can be made lighter in weight and simpler to attach and detach than the connecting device of the prior art. (7) The structure is simple and light, and even a weak nurse can easily attach and detach.
