Or even when the user's upper body is tilted to the left or right during use of the walking vehicle 200, the user can be supported from the left and right directions.

  Referring to FIG. 27, the left and right central wheels 202L and 202R that cannot turn are respectively arranged at positions overlapping with the left and right upper body support frames 230L and 230R in the front-rear direction. More specifically, the rear ends or the ground contact positions of the left and right central wheels 202L, 202R that cannot turn are positioned in front of the rear ends of the left and right upper body support frames 230L, 230R in the front-rear direction. More preferably, the front ends or the ground contact positions of the left and right central wheels 202L, 202R that cannot turn are positioned rearward of the front ends of the left and right upper body support frames 230L, 230R in the front-rear direction, and The rear ends or the ground contact positions of the central rings 202L and 202R are positioned in front of the rear ends of the left and right upper body support frames 230L and 230R in the front-rear direction. Thereby, the stability in the left-right direction of the walking vehicle 200 is improved.

  In addition, the risk of causing unintentional turning is reduced for the user whose left and right upper body support frames 230L and 230R restrict the movement in the left and right directions, and thus the risk of falling is reduced. In other words, when the walking vehicle 200 turns, since the left and right upper body support frames 230L and 230R are positioned on the axis connecting the central wheels 202L and 202R in a plan view, the axis becomes a turning axis and is stable with the user as an axis. You can turn around. In this regard, referring to FIG. 3, similarly, in the walking vehicle 100, the non-turnable rear wheels 102L and 102R are arranged at positions overlapping with the left and right contact support members 131L and 131R in the front-rear direction. Has been. Accordingly, the left and right stability of the walking vehicle 100 is improved. In addition, the risk of causing an unintended turn is reduced for a user whose movement is restricted in the left-right direction by the left and right contact support members 131L, 131R, and thus the risk of falling is similarly reduced.

  In addition, in the present embodiment, each of the left and right central wheels 202L, 202R that cannot turn is disposed at a position behind the front ends of the left and right armrests 220L, 220R in the front-rear direction. As a result, the user can easily use the axis line connecting the central wheels 202L, 202R with respect to the walking vehicle 200 as a turning axis while applying a weight to the left and right armrests 220L, 220R with or without gripping the handle 112. A turning force can be added.

  In addition, in the present embodiment, the front ends of the left and right armrests 220L, 220R are positioned forward of the front ends of the upper body support frames 230L, 202R. As a result, the user can walk stably with his / her own weight in the forward direction.

  Further, in the present embodiment, the front portions of the left and right upper body support frames 230L and 230R are pivotally supported by the left and right armrests 220L and 220R, respectively. Each of the left and right upper body support frames 230L and 230R is fixed at a position where the rear part is rotated upward as shown in FIG. On the other hand, for example, when the user stops using the walking car 200 and sits on a chair or bed, or when the user stands up and starts using the walking car 200, the left and right upper body support frames are shown in FIG. The rear portions of 230L and 230R are rotated downward. Then, as shown in FIG. 28, the left and right upper body support frames 230L and 230R are finally fixed at a position where they are lowered to a position where they do not protrude above the left and right armrests 220L and 220R.

  Thus, for example, when the user moves to the walking vehicle 200, the left and right armrests 220L and 220R are lowered to a low position, and the user moves to the upper body support frames 230L and 230R with respect to the left and right armrests 220L and 220R. The armrests 220L and 220R can be raised and positioned in the walking posture after being able to lean on without being obstructed. Further, when the armrests 220L and 220R are raised and positioned in the walking posture, the upper body support frames 230L and 230R are moved upward in accordance with the rise of the armrests 220L and 220R to lift the upper body (eg, the armpit area). Thus, the user can be more easily positioned in the walking posture. As another use configuration, when raising and lowering the walking car 200, the upper body support frames 230L and 230R support the user to prevent the user from falling due to the raising and lowering of the walking car 200. The user can be safely transferred or positioned in the walking posture without the support of the person.

  In addition, it is preferable that the walking vehicle 200 is equipped with a human sensor around it.

  Furthermore, the walking vehicle 200 preferably includes a guide light. And when a person is detected in the vicinity of the walking car 200 by a human sensor, it is preferable to turn on the guide light. Thereby, even when the room is dark, the user can easily grasp the position of the walking vehicle 200.

  Moreover, it is preferable that the walking vehicle 200 is equipped with an electric motor. And it is preferable that the rear wheels 102L and 102R or the central wheels 202L and 202R that cannot turn are driven by the electric motor. In this case, it is preferable that the walking car 200 has a self-propelled running function by including a camera and a communication device. For example, the walking car 200 preferably has a function of automatically traveling to the charger when the remaining battery level is low.

According to the present invention, the user can be maintained in a stable walking posture by supporting the upper body of the user with the left and right armrests 220L and 220R. In this regard, the user can stably walk using the walking vehicle 200 in a state where the falling in the left-right direction is reduced. On the other hand, when the user moves in the forward direction using the walking car, the walking posture is corrected in the upright direction. For example, the user's physical ability is left and right due to age or disease. If there is a difference, the walking vehicle 200 may be skewed without the user's intention. Therefore, by mounting the electric motor, for example, the rotation speed of the rear wheels 102L, 102R or the center wheels 202L, 202R that cannot turn can be controlled independently from each other, and the occurrence of the skew is suppressed. You can move forward better in the forward direction.
