Abstract

In the cart (10) of invention The load compartment (11) will be supported by at least one stationary wheel (15) and several movable wheels (14). Movable wheels (14) will be installed respectively. With the object (11) at the leading and rear in the direction of movement when the trolley (10) moves the wheel axle (146) of the wheel carrier (142) of each one of the movable wheels (14) being Position on The leading side in the direction of movement will move downward. So the point of contact (145) of the wheel (141) with the displacement surface. Of the wheel is transformed into a condition in which it is at least below the contact point (155) of the wheel (151) of the stationary wheel (15), while the wheel axis (146) of the wheel carrier (142) of each One of the wheels The movable (14) that is positioned on the rear in the direction of movement will move upward, so the contact (145) of the wheel (141) with the moving surface of the wheel is transformed into a state in which it will high Than the contact point (155) of the wheel (151) of the wheel is at (15).

Claims (3)

Disclaimer (all) which will not appear on the announcement page: EDIT 26 May 2017 1. Cart in the cargo area will be supported by at least 1 fixed wheel and capable wheel. Movable with multiple wheels Which has specific characteristics Each movable wheel is installed at the front and rear in the direction of movement of the cargo area when the trolley goes forward. The movable wheels, mounted in the direction of movement, receive friction from the road surface, the movable wheel brace changes direction. Make the wheel center of the stabilizer The wheels move downward. Therefore, the point of contact of the wheel with the moving surface of the wheel is changed to a state in That is, at least the point of contact of the wheel of the stationary wheel with the lowest point of contact. The movable third wheel, installed at the rear in the direction of movement, receives the friction from the road surface, the movable wheel stabilizer changes direction. This causes the wheel center of the wheel carrier to move upward so that the contact point of the wheel with the moving surface of the wheel is changed to a state in which it will Above at least the contact point of the wheel of a stationary wheel with the lowest point of contact While the trolley moves At the leading side in the direction of movement of the trolley, there are wheels that can be touched. To the surface of the movement of the wheels And at the end in the direction of movement there is a fixed wheel that is in contact with the moving surface of the wheel 1. a cart of a model in which the storage compartment is supported by at least one fixed wheel, and Several movable wheels, where the movable wheels are respectively mounted to the cargo hold at the leading and rear in Direction of movement, where when the trolley is moved The axle of the wheel carrier of each one of the movable wheels. Correct position on the leading side in the direction of movement will move downward Therefore, the point of contact of the wheel with the surface The movement of the wheels is transformed into a condition in which it is at least below the point of contact of the wheel of the wheel. Stationary with the lowest point of contact While the caster axis of the caster of each wheel, one of the wheels can move. Has been positioned on the rear in the upward movement direction Therefore, the point of contact of the wheel with the surface The movement of the wheel is transformed into a state in which it is at least the point of contact of the wheel of the wheel. Is stationary with the lowest point of contact, and where while the wheelchair is in motion At the leading side in the direction of movement of the trolley Movable wheels Will touch the surface of the wheel, while the rear in the direction of movement The wheel is stationary to touch the surface of the wheel movement. 2. Trolley as defined in claim 1, where each of the wheels can be moved. It consists of a spindle that acts as the center of rotation when the wheel traction turns around, where when the trolley moves, and the wheels of each one of the movable wheels that are positioned on it. The leading side in the direction of movement is applied to the friction from the road surface. The wheel restraint may turn around while there is Rotation around the spindle And according to the results The position of the wheel inductor may be changed by an inclined surface, so the wheel axis may be moved downwards. 3. Trolley as defined in claim 2, where when the wheelchair moves and the wheel of each one. The movable wheels that are positioned on the rear in the direction of motion are applied to the friction from the road surface, the wheel spacers may turn around while the pivot is rotated. And as a result, the position of the wheel stabilizer may be changed by the inclined surface. Therefore, the wheel axis may be moved upward.
