Description

[Detailed description of the invention]

0001

FIELD OF INDUSTRIAL APPLICATION The present invention relates generally to container shapes made in accordance with both international harmonized standards and other standards intended for the transportation of goods or other more habitable mobile or temporary housing types of use. The present invention relates to cases, tanks and the like, and in particular to a built-in device for the self-raising of a comprehensive tank of this type, which makes it easy to mobilize (move) and position with great spatial precision.

0002

BACKGROUND OF THE INVENTION As is well known, with the widespread use of containers with characteristics that comply with national and international harmonization standards, on the one hand, and on the other hand, the practical implications that the same use can bring to the maximum extent. and numerous problems related to efforts to develop potential benefits had to be resolved.

For example, tanks of this type are equipped with equally uniform corner blocks and fittings, and are equipped with cranes,
It can only be mobilized, ie, loaded, unloaded, moved, etc., by large equipment external to it, such as loader bridges, large lifts, and the like.

0004

The first problem encountered in attempts to improve tank cases of this type is the addition of mechanical or hydraulic legs, so-called "rams", which at the same time fit within their respective predetermined dimensions. It lies in the difficulty of doing things.

A second problem, for which no solution has hitherto been found, is that once the case has been lowered and it becomes necessary to place it in place or in any case move it, the large forces or the practical impossibility of displacing it from the drag, which in any case requires the use of cumbersome equipment.

[0006]

SUMMARY OF THE INVENTION It is therefore a primary object of the present invention to provide a means for facilitating loading and unloading operations on motor vehicles, railway vehicles and the like. The object of the present invention is to realize a tank case of the type described above, which incorporates a mechanical or hydraulic leg that allows automatic lifting of the tank independently of the device.

A further object of the invention is that the movement, or at least the precise adjustment of the position, of the tank itself relative to another surface, for example on a motor vehicle or railcar, also requires the power of one or two people. The object of the present invention is to realize a tank case as described above, in which the self-raising leg is made possible by manual force without using any external equipment.

Further features and advantages of the invention will become apparent from the continuation of the disclosure with reference to the accompanying drawings, in which preferred embodiments are shown by way of illustration and not limitation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Here, the drawings, particularly FIG. 1(a), will be explained. A container, tank or the like 1 in the form of a parallelepiped as defined by the specification shall be provided with an equal number of self-raising mechanical or hydraulic It can be seen that it has four spaces 2 created within its vertical walls to accommodate pressure legs (rams/jacks) 3.

FIG. 1A and FIG. 2 will be explained. A mechanical or hydraulic (hydraulic driven) leg 3 is flag-hinged on the axis 11 by at least two sets of articulated arms 12, 13, so that the leg 3
and from the retracted rest position shown in solid line in Figure 2,
It can be seen that it can be rotated to the extended or activated position, which is shown in dash-dotted lines in the same figure.

Axis 11 is connected to four pairs of vertically arranged corner fittings 4.

[0012] The legs 3 do not necessarily have to be arranged in four sets on the vertical edges of the tank; there may be fewer or more of them to meet specific requirements, and they may also be removable. .

Suitable members for locking the leg 3 to the tank case 1 are indicated by the reference numeral 5 and, if they are permanent parts thereof, retain the leg within a predetermined dimensional contour; or suitable for fixing them in an external or deployed position.

At the lower end of the leg 3 there is provided a support foot 6 of suitable shape and size (circular, square, built-in and the like), which also corresponds to (b) in FIG.
) may be a rotatable roller or wheel 6a.

[0015] Axial multi-joint joint element 7, two sets of bearings,
its radius of rotation, preferably by ball bearings (not shown);
The piston 8 of the self-raising leg 3 as well as the vertical axis 9 of the foot 6 or wheel 6a are of critical importance for the purposes of the invention. It is assumed that the bearings described above are parallel to each other and have different centers.

As will be seen, the above-mentioned axially articulated joint element 7 is important and, in combination with the flag (or waving) movement of the self-raising leg 3, makes it possible and convenient to move the tank by human pressure. Make it into something.

A suitable hydraulic drive box 10 is provided, which may also be internal to the tank, or external to it to serve more tanks.

FIG. 3(a) to FIG. 3(e) will be explained. A tank according to the invention is shown in FIG. 3(a) in its resting position with the legs in their retracted position. In the second stage of FIG. 3(b), the legs are rotated into the external position, for example in the pre-arranged and self-raising position on a motor vehicle equipped for the transport of unified containers. In FIG. 3(c), the tank is self-raising. In the next step, FIG. 3(d), by human pressure acting on the corner fitting and the fixed connection provided on the vehicle, which inserts itself under the tank at the same time as its loading platform. , the tank can be easily centered. Finally, in its external shape, its legs can be retracted and fixed on the car,
A tank ready to be transported is shown in FIG. 3(e).

FIG. 4(a) to FIG. 4(c) will be explained. A clearly repeatable and combinable possibility of horizontal movement by human pressure of 360° and on non-horizontal ground is seen.

[0020]The use of roller feet or wheels, in addition to offering the possibility of actual movement on the ground, also provides greater flexibility in positional arrangement, which means lower stresses on the tension legs themselves. It is desirable to keep an eye on the granting.

Regarding the positioning of the self-raising legs, it allows the use of a suitable tank that precisely abuts another similar tank or abuts the cab of a transport truck, without leaving any intermediate gaps. Therefore, it is timely to state clearly that at least two sets of such legs should be arranged on the sides and not on the front.

As a final observation, it is desirable to conclude that the axially articulated joint element provided between the leg and the foot can also be inserted into the arm of the flag hinge of the self-raising leg.

Although preferred embodiments have been disclosed above and various modifications have been suggested, other changes and modifications in details, details of structure and arrangement may fall significantly outside the scope of protection of the present invention. This can be done by a person skilled in the art.
