The rectangular container (2) is mounted in a two wheeled trolley frame (1) which is supported in a raised setting by two struts. The wheels (3) are set at the ends of expanding struts to position the centre of gravity of the container over the wheels. The frame is tilted over to drop the container flat onto the ground for draining vehicle fuel tanks. The edges of the container have clips (20) which hook onto the tubular frame and hold the container in the selected setting. No pumps are required and the container can be used in the field.

Description

Tank emptying device for automobiles

according to patent (patent application P 30 08 612 ...) In the main patent is a Described tank emptying device, which is used for emptying a motor vehicle tank in a horizontal position and to refill the fuel in grooves vertical 5t; eLlung is respected. With this tank emptying device, you can use the Gravity achieved a particularly economical Arheitweise, with the device is inexpensive and has no wearing parts.

To this tank emptying device from the horizontal to the vertical To bring it into position, it is tilted upwards, the pivot axis being through the wheels is formed.

So that it doesn't roll away when it tips up, one of them is there Embodiment provided that the frame protrudes beyond the circumference of the wheels and thereby the pivot axis is formed in the area of the vertical position. In order to an unstable position in the area of the vertical position is avoided.

On the other hand, the tank emptying device must therefore be transported in be held in a relatively inclined position so that substantial forces are required to hold on must be applied because the center of gravity is far off the axis of the wheels. It must be used when dimensioning the frame part protruding beyond the circumference of the wheels always a compromise between the stable position in the vertical area (in the sense of a Danger of rolling away) when tilting up the tank emptying device and the required Transport forces getting closed.

The invention is based on the object of the tank emptying device in such a way that it is tilted up from the horizontal to the vertical Position cannot roll away at any time, but that for transporting the. main emphasis nevertheless over or to the respectively desired small extent next to the axis of the wheels can be held.

This object is achieved in that the wheels of the Cart are arranged at the end of the support, which protrudes from the frame. It becomes so achieved that the tank emptying device when tilting up without additional elements or tipping down, the fixed end of the frame is secure on the floor at all times and the wheels do not hit the ground until they reach the vertical end position touch. This design allows it to be transported further along the axis of the Wheels are tilted so that the required handles are kept as small as desired can be, while at the same time a high ground clearance of the vertical Rest position on the ground supporting frame end is reached. With that namely also ensured that the tank emptying device during transport with no Part hooked on the floor.

With one telescopic from the support over the wheels In the vertical position, booms can relieve the wheels and at the same time the stand area will be considerably coarser. The increased stability achieved in this way is particularly important if the tank emptying device has been switched off for a long period of time will and with it possibly the risk of accidental knocking over consists.

A significant reduction in the forces required when tipping up from the horizontal to the vertical position is achieved by a tilting edge, which protrudes on a side of the frame facing away from the support and that of a the lower end of the frame is arranged offset towards the container. So that is the beginning the tilting up of the lever arm between the container and the pivot axis is shortened and thus the lever arm ratios force application point - pivot axis to center of gravity - pivot axis Crucially improved, especially when the container is full. The actual framework then only supports itself at a certain incline on the ground, when the helm conditions anyway have become cheaper because the focus is in the direction of yourself has migrated on the ground supporting frame end, the lever arm force application point - The new swivel axis has become larger.

The tilting edge is made in a particularly simple manner by a corner of the Container formed when this the container is slightly inclined to the main direction of the frame can be locked so that the corner of the container formed to the tilting edge protrudes. This means that no additional elements have to be attached to the frame to create the tilting edge apart from the locking device, which is useful anyway. This locking device expediently consists of a bolt movable transversely to the frame on which the Container rests or engages in a counterpart on the container, whereby the container is also secured against pivoting in the second direction.

If between the tipping edge and the one in a vertical position on the floor A curved roller runner is arranged at the end of the frame when it is tipped up the pivot axis continuously from the tilting edge to the vertical position the end of the frame standing on the ground.

There will be a sudden shift in the pivot axis and the associated jump in force avoided.

A simple and inexpensive design is achieved by the Frame is angled in its main direction so that the tilting edge directly is formed on the frame.

The frame can then also be positioned directly between the tilting edge and in a vertical position Position of the frame end standing on the ground must be bent to the roller skid. So be then from the frame without any wearing parts the functions of the tilting edge and the Abrollkufe taken over, with only a simple bending process for production is required. During this bending process, the vertical Position the top ends of the frame to angled handles towards the wheels will. By such angled handles it is achieved that this is in a lying position Position of the tank emptying device have a certain ground clearance and thus light can be seized. In addition, this inevitably results in a vertical position from which side the tank emptying device is expediently to be seized.

The invention allows numerous possible embodiments.

Examples are and are shown schematically in the drawing described in more detail below. As far as possible, the same reference numbers are used as used in the main patent.

FIG. 1 shows a side view of the tank emptying device according to the invention in a vertical position with the container at rest; figure 2 - the tank emptying device of Figure 1 in a lying position, the process tipping up is shown by thin lines indicating the relative position to the ground is; Figure 3 - another embodiment with a curved frame.

The tank emptying device according to the invention consists essentially from a cart 1 and a flat container 2. The container 2 is shown in FIG Rest position shown. The position of the container is indicated by dashed lines 2 indicated for the tank filling. This also includes the position of the fuel connection 10 shown. The auxiliary devices on the container 2, such as the injector, are not shown or strut, which can correspond to the embodiment in the main patent. The basic function when emptying and filling the vehicle tank also corresponds to the im Function described in the main patent, so that repetition is not necessary is.

The main difference to the main patent is the 3 wheels at the end the support 5 is arranged, which protrudes from the frame 4. Furthermore, the container 2 by a Locking device 21 in the illustrated, slightly inclined to the main direction of the frame 4 held extending position. This locking device 21 can be designed as a transversely to the cart in the frame movable bolt 21, the behind the container 2 or in a corresponding counterpart.

It should also be mentioned that the upper ends of the frame 4 from the Main direction to the wheels 3 are angled towards handles. Furthermore is by a thick dashed line the floor and thus the contact area for the Tank emptying device shown.

The tank emptying device is seen in FIG. 1 for transport the handles 24 tilted to the right, making the center of gravity on the Wheels shifted and the tank emptying device can be moved easily.

All fixed parts have a lot of ground clearance, so that none Time during transport, the tank emptying device can get caught on the floor or that it is therefore held in a strong incline that is unfavorable in terms of force would have to; It is seen in FIG. 1 for tipping down into the tank emptying position tilted to the left over the end of the frame standing on the floor 22. The lift Wheels 3 immediately from the ground 22 and there is no time during this process more the risk that the tank emptying device threatens to roll away in an uncontrolled manner. It always stands up on the floor 22 with fixed, immovable parts.

In FIG. 2, the tank emptying device of FIG. 1 is in the tank emptying position shown, in which it rests directly with the flat container 2 on the bottom 22, 90 that not the slightest difference in height to the vehicle tank is given away. It should be noted that the handles 24 protrude from the floor 22 in this position and therefore easy to grasp.

An arrow 25 is the force application point when tilting the Tank emptying device shown. Thin lines show how the Tilting up changes the position of the tank emptying device relative to the ground. It can be clearly seen over which pivot axes the tank emptying device is moved during this process and how the lever arm relationships are change.

At the beginning of the upturn, the tank emptying device is operated via the as Tilt edge 20 formed corner of the container 2 pivoted. The center of gravity of the lever arm. - The pivot axis is very much shorter than the lever arm force application point 25 - swivel axis. If the container 2 is only partially filled, it will still shift the center of gravity with increasing inclination in the direction of the 'pivot axis, because the Fuel always flows to the lower part of the container 2.

Aob a certain inclination, the frame 4 sets on the ground, such as this is illustrated by a floor line 22a. If you tip up further, it will the tank emptying device moves about this pivot axis. The lever arm is the point of application of force - Swivel axis significantly enlarged.

The lever arm ratios are then again more and more favorable because the center of gravity moves to the pivot axis until it passes over the pivot axis and finally the tank emptying device with the wheels 3 on the floor 22 into the stable position shown in Figure 1 comes.

In Figure 3 is a further embodiment of the Tank emptying device according to the invention shown, in which the frame 4 in his Main direction is bent in such a way that the tilting edge 20 directly through the frame 4 is trained. For this purpose, the middle frame part is simply bent out accordingly. In addition, the frame 4 is between the tilting edge 20 and in the vertical position The end standing on the ground is formed into a curved roller runner 23. By this Abrollkufe 23 is a gradual continuous wandering when tipping up the pivot axis from the already rounded tilting edge 20 to the lower Frame end causes. So there is no longer a sudden change in the lever arm ratio instead of, as explained for Figure 2, but a gradual change, which is hardly noticed by the operator.

It should also be noted that in the embodiment of Figure 3, the Support 5 is also formed in one piece with the frame. It is easy to do so a corresponding piece of profile material, from which the frame is also made, for the support angled. The support 5 is bent slightly upwards so that it is defined Riot points arise.
