下方向の防振を図った除振装置が開発された。For example, - Ambulances carried on boats are usually not equipped with vibration isolators, so the stretcher carrying the patient is loaded directly onto the ambulance bed and secured by a fixing device on the vehicle body. It was just that. Therefore, the vibrations of the vehicle body were directly transmitted to the stretcher and patient. Therefore, a vibration isolator has been developed in which a platform for placing a stretcher is provided on the loading platform of a vehicle, and dampers and springs are provided between the platform and the loading platform to prevent vibrations in the vertical direction.
従来の除振装置は、上下方向の振動だけを除振するため
、左右方向の振動は患者に伝わり、患者輸送のスピード
アップは図れなかった。Conventional vibration isolators only isolate vibrations in the vertical direction, so vibrations in the left and right directions are transmitted to the patient, making it impossible to speed up patient transportation.
そこで、この発明は、患者又は輸送対象物への車両の振

れつないだものである。In order to achieve the above-mentioned object, the present invention provides a lower, middle,
A vertical vibration isolating means consisting of an air spring is provided between each upper frame, and a rolling prevention means consisting of a stabilizer or an X-link is provided, and a horizontal vibration isolating means consisting of laminated rubber is provided between the other frames. , the lower frame is connected to the vehicle side, and the upper frame is connected to the transported object side.
この発明の除振装置は、車両の荷台に固定するだけで良
く、車両の大幅な改造を必要としない。The vibration isolator of the present invention only needs to be fixed to the loading platform of a vehicle, and does not require major modification of the vehicle.
