Claims

[Scope of Claim for Utility Model Registration] (1) A triangular structure consisting of a vehicle body provided with a mounting portion, three wheels mounted in a triangular arrangement with pivots on a support plate, and an axle mounted at the center of the triangular arrangement. a wheel mechanism in which wheels are arranged on both sides of the vehicle body and are associated with a rotation regulating means for regulating rotation of the wheels when a substantially vertical load is applied to each wheel; and a wheel mechanism for rotating the axle. The vehicle body support mechanism includes an electric motor, and a crank arm that is compressible and deformable in the length direction and is installed in parallel to the lower part of the vehicle body, and a sled-shaped guide bar is pivotally attached to the lower ends of both crank arms. Electric transport vehicle. (2) A long hole that is elongated in the direction of the axle mounting position is provided at the mounting position of each pivot on the support plate, and the shaft is loosely inserted into the long hole to mount the axle so that it can move up and down. The electric transport vehicle according to claim 1, wherein a friction member is provided at a position where the wheel surface abuts to constitute a rotation regulating means. (3) Using a DC motor as the electric motor,
The electric transport vehicle according to claim 1 or 2 of the utility model registration claim, further comprising a battery mounted at an appropriate position on the vehicle body. (4) A gripping rod is provided at the rear of the vehicle body to guide the movement of the vehicle, and an interlock switch is installed on the gripping rod to control an electric motor that is turned on when the grip is gripped and turned off when the hand is released. Claim 1 of the above-mentioned utility model registration claims,
The electric transport vehicle described in paragraph 2 or 3. (5) The electric transport vehicle according to claim 1, 2, 3, or 4 of the utility model registration claim, which uses a geared motor associated with a ratchet mechanism as the electric motor. (6) The electric motor according to claim 1, 2, 3, 4, or 5 of the utility model registration claim, wherein both lengthwise ends of the sled guide bar are curved upward. Transport vehicle. (7) Paragraph 1 of the above-mentioned utility model registration claim, wherein the lower surface of the sled-shaped guide bar is treated with an anti-slip finish;
The electric transport vehicle according to item 2, 3, 4, 5, or 6.
