DETAILED DESCRIPTION

[0035] FIG. 1 shows an example of a device (1) for salvaging a wrecked, for example burning, motor vehicle, also referred to below as a salvage lance, which has a telescopic cylinder 2 in the form of a telescopic tube, which is shown in the retracted state. The telescopic cylinder (2) is preferably driven hydraulically, for example by water for extinguishing fires. Other linear drives, for example an electric linear drive, are of course also possible.

[0036] A platform 3 is attached at the tip of the telescopic cylinder 2, which can be designed in the form of a carriage or sled. In FIG. 1 the platform 3 is provided with wheels or rollers 4 for easier transport and movement. Barbs or catches 5 are foldably attached by means of a hinge 6 on the platform 3. In the case shown, the catches 5 are shown folded, lying, in rest position. An actuating device in the form of a cable pull 7 is fastened to the short end of the catches 5, which runs along the telescopic cylinder 2 by means of deflections, so that the catches 5 can be raised, i.e. brought into the locking position, by an actuating means 8, as is shown below with reference to FIG. 2. At the top of the telescopic cylinder 2 there are two handles 9 for transporting the salvage lance. The end of the telescopic cylinder 2 is provided with a fitting 10 through which a hydraulic fluid, preferably water such as water for extinguishing fires, can be supplied. Furthermore, at the end of the telescopic cylinder 2 there is a towing eye 11 for a cable winch or a manual cable hoist for pulling back the device 1 and the motor vehicle 12.

[0037] In FIG. 2, the device 1 or salvage lance according to FIG. 1 is also shown in a side view but in the extended state, with the extended telescopic cylinder 2 being shown discontinuous for better illustration and comparison. In this case of the working position the catches 5 are shown folded up in the locking position. This locking position was reached by pulling on the actuating means 8 so that the cable pull 7 acting on the end of the catch 5 pivoted the catches 5 about the axis of the hinge 6 into the vertical.

[0038] The functioning of the device 1 will now be explained in more detail with reference to FIGS. 3 and 4. If a wrecked, for example burning motor vehicle 12 is to be pulled out of a danger area, the salvage lance is carried by two or more firefighters 13 as rescue workers on the carrying handle 9 into the area of the motor vehicle 12 involved in the accident, here behind the motor vehicle 12 involved in the accident. There, a hydraulic hose 14 is then connected to the fitting 10, which is connected on the other side to a pump, for example in a fire engine (not shown). The telescopic cylinder 2 can then preferably be driven with the water for extinguishing fires present in the fire engine.

[0039] However, the telescopic cylinder 2 can also be connected to a hydraulic rescue tool. The hydraulic rescue tool is powered by a high pressure hydraulic pump. Since the pump and working tools are separate from each other, they are connected by hydraulic hoses. The hoses are often on reels for better handling. Optionally, an operating element with a corresponding control can be provided, via which it can be decided, if necessary, whether the salvage lance extends or retracts.

[0040] The telescopic cylinder 2 is extended by means of the liquid, with the platform 3 being pushed on the rollers 4 under the motor vehicle 12 until the catches 5 designed as swivel pins are completely in front of the burning motor vehicle 12. Then the catches 5 are raised by a fireman 13 by pulling on the cable pull 7. The device can then be pulled back, for example by means of a cable winch (not shown), which is hooked into the towing eye 11, with the catches 5 pulling the burning motor vehicle 12 out of the danger zone.

[0041] FIGS. 5 and 6 show the fully extended device 1 in a side view and top view with the catches 5 folded together, so that they are ready for use.

[0042] FIGS. 7 and 8 now show the fully extended device 1 in a side view and top view with the catches 5 folded up and ready for use, so that they could pull the burning motor vehicle 12 out of the danger zone.

[0043] FIG. 9 shows an alternative embodiment of the device according to the invention, in which the platform 3 is provided with a locking device, for example a locking hook 16, for the catches 5, which keeps the catches 5 in the rest position against the force of a tension spring 15. The locking device can then be triggered by the cable pull 7. After the cable pull 7 has unlocked the locking hook 16, the catches 5 are pulled up by the tensioned tension spring 15, so that when the salvage lance is pulled back, the burning motor vehicle 12 is also pulled back.

[0044] In a further embodiment, the catches 5 can be held folded up by the tension spring 15. If the platform 3 is pushed under the burning motor vehicle 12, the catches 5 are folded down against the force of the tension spring 15. Only when the platform 3 comes out from under the burning motor vehicle 12 do the catches 5 fold back up and when the salvage lance 1 is pulled back, the catches 5 pull the burning motor vehicle 12 back with them.

[0045] FIG. 10 shows an alternative design of the catch 5 in a top view. Here grippers 17 are arranged at the tip of the platform 3, the joint 18 of which is fixed on the platform 3. The gripping jaws 19, 19 of the grippers 17 can bite, for example, on a wheel of the motor vehicle. The ends 20, 20 of the respective two-armed levers opposite the gripping jaws 19, 19 are connected to one another via an actuating cable 21. The cable pull 7 engages in the middle of the actuating cable.

[0046] If the actuating means 8 of the cable pull 7 is pulled, the levers pivot with the ends 20, 20 about the joint 18. At the same time, the gripping jaws 19, 19 are pivoted toward one another for clamping the motor vehicle 12 or for clamping parts of the motor vehicle 12. After the clamped connection to the motor vehicle 12 has been established, it can be pulled out of the danger zone by the device 1

[0047] In summary, it can be stated that this type of device 1 allows the firefighters to safely salvage the burning motor vehicle 12. The salvage lance can be positioned by the firefighters 13 at a large distance from the danger zone. The telescopic cylinder 2 is then extended so that the platform 3 is moved into the working area of the catches 5 in the area of the motor vehicle 12. There, the catches 5 mounted on the platform 3 are actuated by means of the cable pull 7. Then the device 1 can be pulled back together with the motor vehicle 12. Since the fire brigade always has water, the telescopes of the salvage lance 1 is preferably operated by applied water.
