Definitions

• the present invention relates to a rescue device with the further features of the preamble of patent claim 1.
• the previously known portable rescue devices are, for example, spreading tools or combined cutting-spreading tools which, for. B. serve to open an accident vehicle and to rescue the people inside.
• a rescue device comprises tool halves pivotably arranged on a head part, each of which has a working tip.
• different opening widths of the tool halves are required. So z. B. when spreading a jammed door or when moving seats large expansion openings and only comparatively low forces to apply. In contrast, z. B. when opening a door gap to expose hinges, high forces and only small opening widths necessary.
• At least one working tip of the rescue device is attached to the respective tool half in a longitudinally displaceable manner.
• the opening width can also be correspondingly changed when the tool halves are pivoted.
• the lever arm With the change in the opening width, the lever arm also changes, so that different forces can be applied depending on the positioning of the working tip. Due to the longitudinal displacement of the working tip, the opening width and the forces required for use can be changed quickly and easily. No additional spare parts have to be carried to adapt the rescue device to the respective requirements.
• the rescue device remains compact as a portable unit.
• the working tip is expediently attached to each half of the tool so that it can be adjusted so that the optimum opening width can be set and a uniform distribution of forces between the two tool halves is ensured.

• This two-part construction of the tool half ensures a stable longitudinal displacement of the working tip.
• the guide part can be fixed to the receiving part in at least two positions, so that the respectively set arm length is retained even with high force and z. B. the spreading process can be carried out safely and quickly.
• the receiving part can have a shaft in which the guide part is longitudinally displaceable.
• the shaft on the one hand ensures a stable opening function of the tool halves even when the tool arm is extended, since the shaft still provides a secure connection between the receiving part and the guide part even when the guide part is pulled out represents.
• the shaft offers protection against external influences, e.g. B. before contamination or mechanical influences, so that the longitudinal displaceability of the guide part is always quick, easy and can be carried out in the desired pull-out length without jamming.
• the guide part has a shaft in which the receiving part is longitudinally displaceable.
• the guide part can be fixed to the receiving part in a specific position by means of at least one securing bolt which connects the two parts.
• the securing bolt In the inserted state, the securing bolt can penetrate a hole in the receiving part and a hole arranged directly below it on the guide part.
• the fixing by means of the safety bolt can be carried out easily and quickly and also represents an inexpensive way of securely fixing the arm length.
• the securing bolt can expediently be flush with the surface of the guide part and / or the receiving part, so that it is not a hindrance in use.
• the securing bolt can have a laterally arranged recess into which a spring-loaded projection arranged on the receiving part or on the guide part engages.
• a spring-loaded projection arranged on the receiving part or on the guide part engages.
• the recess can be semicircular.
• the recess advantageously extends around the entire circumference of the securing bolt so that it engages with the protrusion in every inserted position.
• the safety bolt In order to always have the safety bolt within reach when in use, it can be connected using a flexible connecting part, e.g. B. a chain, be attached to the receiving part or on the head part.
• the flexible connecting part ensures that the securing bolt is inserted into the bores on the receiving part or on the guide part at different distances from the attachment point of the connecting part. The safety bolt is therefore always secured against loss and is always within reach.
• the guide part can have reinforced outer edges.
• the shaft can expediently have grooves extending in its longitudinal direction, in which these outer edges are guided.
• the working tip can e.g. B. have a sawtooth-shaped outer profile, which in particular for spreading z. B. a vehicle door has extremely advantageous barbs for clamping in a gap in the vehicle door.
• the work tip can also be designed for other functions and z. B. have a cutting edge so that the rescue device can also be used as a cutting device.
• the rescue device with its longitudinally displaceable arm tips can therefore be used as a spreading device and / or as a cutting device and / or as a pulling device.

• Reference number 1 designates the rescue device in its entirety.
• the rescue device 1 has a head part 2, on which two pivotable tool halves 4, 5 are arranged via a coupling element 3.
• the tool halves 4, 5 each have a working tip 6, the z. B. in the closed state a can be inserted in the gap of a jammed car door and pivoted outward to open the car door in an open position b. Since different expansion openings and different forces are required depending on the area of use, it is provided according to the invention that the working tips 6 are attached to the respective tool half 4, 5 so as to be longitudinally displaceable. It is thus possible that different opening widths of the working tips 6 can be set without additional components being necessary or the tool halves having to be replaced with tool halves of different arm lengths.
• FIGS. 1, 2 and 3 show the advantageous portable unit of the rescue device 1 with only one tool half 5 in the closed a and in the open position b for a better overview and for better understanding.
• the dashed lines show the extended positions of the Working peaks 6 reproduced.
• the respective tool half 4, 5 comprises a receiving part 7, to which a guide part 8 connected to the working tip 6 is arranged to be longitudinally displaceable.
• the guide part 8 to the receiving part 7 can be fixed in two positions, so that the set arm length and thus the desired opening width of the tool halves 4, 5 are retained even when a force is applied.
• the receiving part 7 has a shaft 9 (in dashed lines) into which the guide part 8 is longitudinally displaceable.
• the shaft 9 thus protects against contamination, mechanical influences from the outside or the like.
• the guide part 8 can be fixed to the receiving part 7 by means of a securing bolt 10 in a certain position.
• the securing bolt 10 passes through a bore 11 on the receiving part 7 and a bore 12 on the guide part 8 in the inserted state.
• the bores 11, 12 are arranged one above the other in the extended position of the guide part 8, so that the securing bolt 10 can be inserted to fix the position of the long tool arm. 4, the securing bolt 10 also prevents an undesired arm extension of the tool half 5.
