A cover 105 that covers the legs is provided at the lower part of the box. An opening 104 is formed in the cover 105 so that a space (a gap between the lower surface of the box body and the base plate) formed by the leg portion 103 is a fork entry portion into which a fork of a forklift for moving a container can be inserted. I have. As shown in FIG. 6, such an aircraft container is fixed in the aircraft by a fixing device 106 in which a locking portion 102A formed on a container base plate 102 of the aircraft container is provided below the aircraft cargo compartment floor 109. No other securing means is used. The fixing device 106 is composed of a hook 107 and a driving means (eg, a hydraulic cylinder) 108 for driving the hook.
A can be locked.

By the way, as air cargo in recent years, the transportation of electronic devices, precision instruments, fresh foods and the like has been increasing year by year.
Many of these cargoes are sensitive to vibration and shock, and the vibrations and shocks generated during transportation may cause looseness and slack in the product assembly. You need to be careful. However, although the strength of the above-mentioned aircraft container used at present is sufficiently considered, the above-mentioned vibration is not always sufficient, and anti-vibration measures are urgently required.

[0005] Against this background, there have been proposed pallets and the like which are provided with measures against vibration (Japanese Patent Laid-Open No. 11-189242).

Numeral 0 denotes a top panel 112 on which luggage is placed, and leg portions 1 provided at a lower portion of the top panel and configured as vibration isolating means for supporting the top panel while securing an interval into which a forklift claw is inserted.
The legs 111 are made of materials 111a and 111b having a cushioning property in order to exhibit an anti-vibration function, and a plurality of the legs 111 are alternately arranged in a lattice point with respect to the top panel. ing. Cargo is on this pallet 11
In this state, it is stored and fixed in a container by a forklift in a state where it is placed on the zero. For this reason, vibration from the aircraft can be suppressed by the vibration damping function of the pallet leg 111 itself, and effective damping can be performed even for various vibrations. Damage due to vibration can be minimized.

[0006]

However, when the vibration isolating means is provided on the pallet itself stored in the container as described above, the following problems occur. That is,
Loading the anti-vibration pallet in the container causes an increase in the weight of the container and a decrease in the internal volume of the pallet, thereby deteriorating the original container performance. Further, a means for fixing the pallet itself in the container is required, which causes another problem such as further increase in weight.

Accordingly, the present invention provides an anti-vibration means which also serves as a support member for a box between a box constituting a container and a base plate;
By attaching the stopper means, it is possible to reliably prevent the transmission of vibrations to the cargo while substantially satisfying the strength and safety standards of the conventional container without significantly changing the configuration of the conventional aircraft container. An object of the present invention is to solve the above problems by providing an anti-vibration container for an aircraft. In this anti-vibration container for an aircraft, the legs forming the fork entry for fixing the conventional base plate and the container floor are removed, and the anti-vibration means and the stopper means are attached to the anti-vibration container so that the entire container is anti-vibration. As a result, the same volume as that of the conventional container can be secured, and the increase in weight can be suppressed much smaller than that of the pallet.
