THE CART ABLE TO CARRY GOODS EASILY AT STAIRS |
摘要 |
PURPOSE: A carrying apparatus for carrying objects on stairs is provided to easily transfer objects even on a slope road requiring a lot of by using a principle of force distribution. CONSTITUTION: A fly wheel is adapted for using a stair cart with human strength without any battery cell, wherein a small wheel(12) of the fly wheel rotates a big fly wheel(11) for executing movement of a cart wheel and lift(18) with less force. A power motor(13) rotates butted with an inner saw-tooth gear of the fly wheel. A lift has a lift gear to rotate by a gear for lifting and descending. The gear delivers power to a lift-power-delivery-gear and to a lift-power-no-transfer shaft. As power delivery is not demanded, the lift gear and the lift-power-no-transfer shaft contact with each other by a power deliver S/W(16) for stopping operation of the lift. When lifting over stairs, a cart wheel rises up as high as the stairs and the lift rotates reversely using a handle and a brake to move stairs.
