A movable umbrella base comprises a housing (1), a wheel frame (2) disposed under the bottom of the housing (1), at least three wheels (3) connected at intervals to the wheel frame (2) and located partially under the wheel frame (2), a plurality of air bags (4) located inside a space defined by the wheel frame (2) and the housing (1), and a plurality of elastic members (6) limit displacement of the wheel frame (2) and the wheels (3) from the housing (1); when the air bags (4) are inflated, the housing (1) is lifted up relative to the wheel frame (2) and the wheels (3) from the ground; when the air bags (4) are deflated, the housing (1) is lowered relative to the wheel frame (2) and the wheels (3) and contacts the ground. The umbrella base can be moved by the air bags (4), the whole operation process is easier, and it saves more time and effort.

The device comprises a combination of an inflatable air cushion member of a flexible but non-stretchable air tight sheet material and a support block. The inflatable air cushion member is formed as a bag unit comprising opposite layers of said sheet material provided face to face and joined along an edge area to form a double layer edge.

The jack includes an upper support portion (upper plate) fixed to the lower portion of the vehicle body, and an airbag provided below the upper support portion (upper plate) and inflated and deployed by the supply of gas. According to the jack, the airbag is inflated and deployed under the vehicle body by the supply of the gas. When the gas is further supplied to the airbag in contact with the ground, the vehicle body fixed to the upper support portion (upper plate) is lifted. When the vehicle body is lifted in this manner, the state of contact between the wheels and the ground is changed, and the vehicle can escape from the stacked state.
