していた。 Conventionally, as shown in FIG. 1, an air cushion device includes a platform 1 on which a load is placed, a support member 2 formed on the underside of the platform 1 for seating on the floor, and a support member 2 formed on the underside of the platform 1 for seating on the floor. Annular diaphragm 3 for blowing out air
The one consisting of the following has been widely known as Special Publication No. 54-569. This air cushion device is installed in the air chamber 4 of the platform 1 in a suitable manner.
The pressurized air supplied to the diaphragm 3 is introduced into the diaphragm 3 through an inlet 5 connected to the diaphragm 3, and this pressurized air is ejected from an outlet 6 provided in the diaphragm 3, thereby floating the main body of the device. let me,
The purpose of this is to make it possible to easily move heavy loads by reducing the contact resistance with the floor surface 7 due to the load of the load to zero, but in the process of moving, unevenness may occur on the floor surface 7. If a portion of the diaphragm 3 falls into the unevenness and the platform 1 is tilted, the internal air pressure will move to the inner surface of the diaphragm 3 on the opposite side of the depression, creating a strong pressure. After the diaphragm 3 is partially pulled out from the uneven surface, strong air pressure moves to the low-pressure part of the depressed part, and as a result of repeating this state, the platform 1 is rolled significantly, which deteriorates the stability of the main body of the device. It had certain drawbacks.

In a device consisting of an annular diaphragm for ejection, the tube made of soft elastic material connected to the pressurized gas supply device is placed on the floor surface so that the diaphragm does not expand and come into contact with the floor surface during normal operation. By attaching the tube to the bottom surface of the platform in the outer circumferential direction of the diaphragm with an appropriate interval between the two tubes, and supplying pressurized gas from the pressurized gas supply device to the tube in response to vibrations of the diaphragm, the pressure is lower than the internal pressure of the diaphragm. It is made by maintaining strong internal pressure in the tube.

た浮上および移動を可能とするものである。 Since the present invention is formed as described above, if a part of the diaphragm falls into unevenness on the floor and the platform is tilted, the diaphragm will be subjected to vibration in response to the vibration caused by this fall. Pressurized gas is supplied from the pressurized gas supply device to the tube in the falling direction, and this tube provides appropriate buffering with an internal pressure stronger than the internal pressure of the diaphragm, reducing the falling deformation of the diaphragm, and reducing the falling part. This prevents strong pressure from being applied to the inner surface of the diaphragm on the opposite side, and also prevents strong air pressure from moving to the low-pressure part of the depression even after a part of the diaphragm is pulled out of the uneven surface. Even if a part of the diaphragm falls into the unevenness of the platform, the inclination of the platform should be kept to a minimum and the rolling of the platform should not occur.
Even if a small amount occurs, it can be stabilized quickly, and the main body of the device can be stably floated and moved when transporting heavy objects.

である。 Furthermore, during normal operation when the diaphragm 24 is inflated, the tube 30 is urged toward the floor surface 22 by an internal pressure stronger than the internal pressure of the diaphragm 24.
An appropriate number of annular or plurally divided parts are installed on the lower surface of the platform 20 in the outer peripheral direction of the diaphragm 24 at an appropriate distance from the floor 22 so as not to come into contact with the floor 22. is forming. The tube 30 is fixedly formed on the lower surface of the platform 20 on the outer periphery of the support member 23, and its lower surface is located at an intermediate portion between the lower surface of the support member 23 and the lower surface of the diaphragm 24. Further, the tube 30 is connected to a pressurized gas supply device 33 such as a compressor via a connecting pipe 31, and when the main body of the device is not in operation, the pressurized gas in the tube 30 is removed together with the diaphragm 24, and the support member To facilitate seating on a floor surface by a person 23. and,
Pressurized gas is supplied to the tube 30 by sensing the occurrence of vibrations in the diaphragm 24 and in response to the occurrence of vibrations. This vibration generation can be detected by installing a vibration meter 34 on the platform 20, and transmitting electric pulses generated by the vibration meter 34 to the tube 3.
In response to the electromagnetic valve 35 of the supply/exhaust mechanism to the tube 30, the tube 30 is supplied with/exhausted. Furthermore, pressurized gas is supplied to the tube 30 via a pressure regulating valve 36 between the supply device 33 and the solenoid valve 35, so that an internal pressure stronger than the internal pressure of the diaphragm 24 is applied to the tube 30 at the floor surface. This is to hold it in the same direction.
