Abstract: A pushcart according to the present disclosure provides a warning on the basis of a first weight at a position outside a region between a shaft of front wheels and a shaft of rear wheels when viewed from the vertical direction and a predetermined weight. For example, the predetermined weight is the weight on a mounting portion located between the shaft of the front wheels and the shaft of the rear wheels when viewed from the vertical direction. When the first weight is larger than the predetermined weight, an informing unit can provide a warning by using a sound, light, and the like and enable a user to recognize that there is a possibility that the pushcart will turn over.

Abstract: A support unit is connected to a shaft of a main wheel and thus is always maintained in parallel to or at a predetermined angle to a road surface, independently of an inclination angle of a main body. Accordingly, an incline estimating unit regards an inclination angle θ3 being a value in an inclination sensor as being equal to an inclination angle θ2 of the road surface (or in a case where the support unit is inclined a predetermined angle to the road surface, an angle from θ3 to the predetermined angle is subtracted from or added to the crossing angle) and outputs the estimated inclination angle θ2 of the road surface to a target inclination angle determining unit.

The first housing includes a first outlet, the rotating body includes a first coupling port and a first coupling path, and the second housing includes a first inlet and a second outlet. The rotating body is configured to rotate between a first position and a second position. At the first position, the first outlet is coupled to the first coupling port in a state that the first housing and the second housing are separated from each other. At the second position, the first housing is attached to the second housing by the rotation of the first housing to approach the second housing in a state that the first outlet is coupled to the first coupling port.

Abstract: A handcart (includes a main body unit, a pair of main wheels provided to the main body unit, a grip unit that is provided to the main body unit and gripped by a user, a grip switch that detects whether the user is gripping the grip unit, a tilt angle sensor, a camera, an acceleration sensor, or other devices that detect the state of the cart body, and a wheel lock mechanism that locks the main wheels if the grip switch does not detect user's gripping of the grip unit and if the cart body is in a predetermined state, for example, if it is detected by the acceleration sensor or other devices that the cart body is moving. This configuration provides a handcart that locks the wheels without necessarily compromising usability.

Abstract: A pushcart includes a main body, a pair of main wheels, a supporter, an auxiliary wheel, a blocking unit, a switching lever, a slope angle sensor, a gyrosensor, a driver unit, and a supporter rotary encoder. The supporter rotary encoder detects an intersecting angle which is an angle formed by the main body and the supporter, and outputs the detected result to a controller. The gyrosensor detects an angular velocity of the main body in a pitch direction and outputs the detected result to the controller. The controller performs inverted pendulum control in a first control mode based on the detected results of the gyrosensor and the supporter rotary encoder. The controller performs inverted pendulum control in a second control mode based on the detected result of the gyrosensor.

Abstract: A step board is attached to a main body in a rotatable manner. The step board is biased toward the upper side due to a tensile force of a spring while taking a position at which the step board is attached to the main body as an axis, and an attachment angle thereof is so fixed by a stopper as to fall within a predetermined angle. On the lower side of the step board, a cylinder unit covering a side surface of the bar-like main body is provided. The cylinder unit is connected to a brake shoe. Accordingly, when the step board is stepped on, the cylinder unit is moved downward so that the brake shoe makes contact with part of a rear wheel, thereby limiting a rotational velocity of the rear wheel.
