[0046] FIG. 10 is a greatly simplified partial sectional representation of a rescue device according to the present invention using a planar display.

[0047] FIG. 1 shows a first embodiment of a rescue device according to the present invention. The reference numeral 1 designates the rescue device in its entirety. The rescue device 1 shown in FIG. 1 is a cutter device (cutter) which is used, for example, by emergency personnel to free people who have had an accident in road traffic. The rescue device 1 is portable, i.e. it can be carried by hand by an operator.

[0048] The rescue device 1 comprises a housing 2, with a hydraulic cylinder 5 connected to the front side of the housing. In the front region of the rescue device 1 there are two tool halves 6a, 6b. In the example shown in FIG. 1, there are two cutting edges. In addition, the rescue device 1 comprises a cover 7 and a first hand grip 3, which serves as a carrying handle, in the region of the hydraulic cylinder 5, and a second hand grip 4, which is gripped around during use, in the region of the housing 2. In the region of the second hand grip 4 there is a handle 9, for example a so-called star grip, with which the relevant working direction of the tool halves 6a, 6b can be selected by the operator.

[0049] During use, the rescue device 1 is held by the operator with two hands on the two hand grips 3, 4.

[0050] In addition, the rescue device 1 comprises a video-enabled display 8. A “video-enabled display” is to be understood as a display which is able to play back or display video data VD, that is to say films or film sequences. The video data VD can be played back as black and white films or as color films. The video data VD are so-called user guidance data, that is to say video data relating to the use of the rescue device 1. This makes it possible, during use, for the user of the rescue device 1 to play video data VD relating to the use of the rescue device 1 on the vehicle that has actually been involved in the accident, for example after arriving at a car that has been involved in an accident. For example, he can use this to display where or how the high-voltage supply can be deactivated in the car. The user of the rescue device 1 is thus “guided” in his rescue measures by first deactivating the high-voltage circuit of the car and then cutting through electrical connections with the rescue device 1.

[0051] The video-enabled display 8 is preferably a so-called touch screen, i.e. a display via which control commands can be entered by the user by touch.

[0052] FIG. 2 shows the essential functional elements of the rescue devices 1 of the individual embodiments in a greatly simplified schematic representation. The mechanical part of the rescue device 1 is located in the upper region of FIG. 2. This comprises a hydraulic tank 16 for storing hydraulic fluid and a hydraulic cylinder 11 with a piston rod 12 which is located therein and is connected to the tool halves 6a, 6b via a mechanical linkage 10. Depending on the position of the piston rod 12, due to the mechanical linkage 10, the tool halves 6a, 6b are either moved towards or away from one another. The reference numeral 13 denotes a so-called multi-way valve, which determines whether the piston rod 12 is extended or retracted in the hydraulic cylinder or whether the controller 5 is in a passive state in which hydraulic fluid is only fed back from the hydraulic tank 16 to the multi-way valve 13 and in bypass mode. To operate the multi-way valve 13, a handle 9 is provided which, in the example shown in FIG. 1, is designed as a star grip.

[0053] Furthermore, the rescue device comprises a hydraulic pump 14 and a compensation device 17 on the tank, which ensures that volume compensation can take place depending on the position of the piston rod 12 within the hydraulic cylinder 11.

[0054] The hydraulic pump 14 is controlled by an open- and closed-loop control unit 21, which is also shown schematically in a highly simplified manner in FIG. 2. It comprises a processor 18 with a memory 19 and a battery 15 which is carried on the rescue device 1. In addition, the open- and closed-loop control unit 21 also includes the video-enabled display 8 and a loudspeaker 23 for reproducing audio data.

[0055] In order to supply the video-enabled display 8 with corresponding video data VD, a communication interface 20 for video data VD is provided. Via the communication interface 20, video data VD can be transmitted to the rescue device 1 or the open- and closed-loop control unit 21 thereof, stored in the memory 19 and can be retrieved via the processor 18 if required. The control and/or command input is preferably carried out via the video-enabled display 8, which is designed as a touch screen.

[0056] In addition, if required, not only video data VD but also audio data AD can be transmitted to the rescue device 1 via the communication interface 20.

[0057] The video-enabled display 8 expediently has a protective layer 8a which is permanently fastened to the display 8, cf. FIG. 10. This can be a glass layer or a transparent plastics layer. A so-called touch foil 8b is located below it. Below this is the display layer sequence 8c, which can be, for example, a so-called LCD display (liquid crystal display).

[0058] FIG. 3 shows a further embodiment of the rescue device 1 according to the invention, in which the video-enabled display 8 is covered by means of a protective cover 22. The protective cover 22 ensures that the display 8 cannot be damaged during storage and also during use of the rescue device 1. The protective cover 22 is a cover which is effective against impact, pressure and/or scratch damage and which surrounds the display 8. The protective cover 22 is only removed, i.e. the display 8 is exposed, when the user requires information from the display. For this purpose, the protective cover 22 can be fixed to the housing 2 of the rescue device 1 via a suitable mechanically releasable connection, for example a latching or snap connection (not shown in each case) or at least one holder. If necessary, as shown in FIG. 4, the connection can be released to expose the display 8, so that the protective cover 22 can be removed.

[0059] In the embodiment of the rescue device 1 according to FIG. 5, the protective cover 22 remains on the rescue device 1 during storage and operation. However, its position in relation to the display 8 or housing 2 can be changed. In the example shown in FIG. 5, the protective cover 22 is fastened to the housing 2 or display 8 in such a way that it can be displaced in the direction of the tool halves 6a, 6b, that is, along the main extent of the rescue device 1, as a result of which the display 8 is exposed. If the operator has received the information, the protective cover 22 is moved back into the starting position over the display 8.

[0060] Alternatively, as shown in FIG. 6, the fastening of the protective cover 22 can also be designed in such a way that the protective cover 22 can be opened to the side of the display 8. This also enables the display 8 to be exposed quickly and subsequently reclosed.

[0061] According to an expedient embodiment of the present invention, the display 8 can also be designed as a so-called folding display. Here, too, the display 8 comprises a protective layer 8a, a touch foil 8b and the actual display layer sequence 8c. However, the protective layer 8a, like the touch foil 8b, must be flexible in this case. In the folded state according to FIG. 7b, the display 8 is protected against mechanical impairment. If the user requires information, he only needs to unfold the folding display, as shown in FIG. 7a. On the underside of the display 8, the outline of the housing 2 is shown in a greatly simplified manner.

[0062] According to a particularly expedient embodiment, the display 8 can also be curved, as shown in FIG. 8. The respective layers 8a, 8b and 8c are omitted in the illustration according to FIG. 8 for the sake of clarity. However, the curved display 8 according to FIG. 8 can also contain the layer sequence 8a-8c. The curved display 8 ensures that the user can see the video data VD even better during use. In addition, the curvature of the display 8 adapts approximately to the curved course of the housing 2.

[0063] From FIG. 9 it can be seen how data can be transferred to the rescue device 1. Correspondingly, near-field communication, wireless communication or wired communication can be established via the communication interface 20, see FIG. 2, with a portable computer 26, expediently a smartphone or hand-held device. In the embodiment shown in FIG. 9, wireless communication 24 is provided between the portable computer 26 and the rescue device 1. The data of the portable computer 26 can in turn be transmitted by the latter, for example via a GSM communication network 25 or WAN network. The reference numeral 27 shows an example of a transmission mast of the GSM communication network 25.

[0064] The communication interface 20 is, for example, a near-field communication interface or an RIFD-based interface, also called an NFC interface. With such communication, the portable computer 26 or the smartphone is brought into close proximity to the corresponding receiving part in the open- and closed-loop control unit 21 of the rescue device 1, whereupon data can be transmitted.

[0065] Alternatively, a wireless communication interface with a maximum range of 100 m, preferably a Bluetooth interface or a WLAN interface, can also be provided. As an alternative or in addition, it is also possible to transfer data from the portable computer 26 to the rescue device 1 by cable.

[0066] The rescue device can also be switched on and/or off in an advantageous manner via the display 8, i.e. by actuating the display 8. A separate mechanical on or off switch is thus no longer necessary.

[0067] It is emphasized that the rescue devices 1 of the present examples can also be a spreader or a so-called combination device, which can be used both for cutting and for spreading. Likewise, a rescue device according to the invention can also be a so-called rescue cylinder which has only one hand grip and is guided by the operator with only one hand during use. When using a rescue cylinder, it is also very important to be able to retrieve user guidance data quickly during the operation if necessary.

[0068] It is expressly pointed out that sub-combinations of the features of the individual embodiments of the invention described in the text are also considered to be included in the subject matter of the invention.
