    Furthermore, there is also a need in special cases where great consideration must be given to the object's appearance or precision that a transmission of a rotating torque does not cause the objects negative damage (scratches, edge impacts, etc.). This can occur when installing and assembling, for example, works of art, jewelery or other decoration or advanced scientific equipment specially developed for very special purposes. There is a need here for aids that can ensure that the tools for transmitting torque do not slip or otherwise lose grip in an undesired manner.
    A further problem with known types of wrenches is that the object to which the rotating torque is to be transmitted can slide out of the tool in connection with the object being operated with the wrench. This can, for example, lead to the skull of a screw, nut or the like being pulled around, ie damaged. Furthermore, the person performing the work with the wrench can easily be injured, for example on the hand with which the wrench is operated, in connection with the wrench involuntarily coming loose from the operated object.
    A further problem with known wrenches is that they easily slip, which means that they easily cause screw heads and the like to be pulled round.
    Prior art Tools of the wrench type, which was originally called a wrench by the inventor Johansson, are already known. For example, the original wrench is described in the Swedish patent specification SE4066. The wrench has proven to be a great commercial success and it has been sold in very large numbers.
    Furthermore, tools such as fixed keys have been developed through the ages. However, these are limited to a specific dimension. In addition, so-called polygrip pliers have been developed.
    The previously known tools have a number of shortcomings which limit their usefulness.
    For example, it is not possible to maneuver all types of objects with these pliers.
    Applicant's patent application SE0700664 describes an addition to a tool which comprises arcuate abutment surfaces. The construction according to the patent specification SE0700664 differs to a large extent from that of the present invention. For example, the construction according to the patent specification SE0700664 is not intended to be used for transmitting a rotating moment to an object but is intended to hold and temporarily fix one or more objects. Although the above constructions may individually serve the purposes thereof, none of them constitute a construction in accordance with the present invention.
    Brief Description of the Invention The main object of the present invention is to provide a considerably improved tool for holding objects as well as transmitting rotating torques to a screw head nut or the like. A further object of the present invention is to provide an aid which allows one and the same tool to be used for your shapes and dimensions other than what it was designed for. An even further object is to provide an aid which in a reliable and very gentle manner transmits rotating moments to and between objects which are very sensitive to negative damage.
    Detailed Description of the Invention The invention will be described in more detail in the following with reference to the accompanying schematic drawings which, by way of example, show the presently preferred embodiment of the invention.
    Figure 1 schematically shows the present invention seen in perspective.
    Figures 2A - 2C show alternative embodiments of abutment surfaces.
    Figure 3 shows a second alternative embodiment of the present invention.
    Figure 4 shows a third alternative embodiment of the present invention.
    Figure 5 shows a fourth alternative embodiment of the present invention.
    With reference to figures, a tool 1 is shown in accordance with the present invention.
    The construction comprises at least one lever 2 and at least one grip 3, the grip of which comprises at least a first jaw 4 and a second jaw S. The lever 2 preferably consists of a shaft or the like. The design of the slopes 4 and 5 can vary greatly within the scope of the present invention. Furthermore, the jaws 4 and 5 are preferably spaced apart to be adjustable with an adjusting member 6. The adjustment can take place by that jaw being fixed and the other movably arranged as is the case in a wrench, polygrip or the like. Alternatively, the implement can be designed so that both jaws are movably arranged. The design of the shaft (lever) can vary widely within the scope of the present invention.
    For example, the shaft may have a corresponding construction as known types of wrenches or the like, as shown for example in Figure 1. Alternatively, the levers may be a first and a second operating member as is the case in a polygrip as shown in Figure 3.
    The unique thing about the present invention is that each jaw comprises at least one recess 7. The recess 7 comprises a first abutment surface 8 and a second abutment surface 9 which connect to each other a tip 10. The abutment surfaces 8 and 9 can be arcuate or straight. In the first embodiment, shown in Figure 1, the first abutment surface 8 and the second abutment surface 9 are arcuate. The arcuate shape may be of an elliptical shape, radial shape or of another arcuate shape suitable for the purpose. The first abutment surface 8 and the second abutment surface 9 form a tip 10.
    Figures 2A and 2B show a variant with straight abutment surfaces (infinite radius) on the abutment surfaces. The angle 1 1 between the first abutment surface and the second abutment surface in ranges of 85 to 165 degrees. Preferably, however, the angle 11 between the first abutment surface 8 and the second abutment surface 9 is about 120 degrees. Figure 2A also shows an actuated object 12. In variants of the present invention, one of the abutment surfaces 8 or 9 may be arcuate and the other of the abutment surfaces 8 or 9 may be straight as shown in Figure 2C.
    More specifically, Figure 1 shows a tool of the wrench type whose jaws 4 and 5 are provided with arcuate abutment surfaces 8 and 9.
    Figure 3 shows a variant of the tool in accordance with the present invention, where it essentially consists of a tool of the polygrip type. Figures 3 do not show parts of the handle, but this is designed in accordance with known technology.
    Figure 4 shows a variant of the present invention where the respective jaws 4 and 5 are provided with a first recess 7 and a second recess 13 with arcuate abutment surfaces 8 and 9.
    Construction can consist of a tool with a similar construction such as a wrench, polygrip or other tool suitable for the purpose, which is provided with recesses 7 with arcuate abutment surfaces 8 and 9. Figure 4 does not show the handle, but this is designed in accordance with prior art.
    More specifically, a tool with loose jaws 14 and 15 is shown in Figure 5. The loose jaws 14 and 15 can be applied to existing jaws as shown in Figure 2, for example. The loose jaws 14 and 15 each comprise at least one recess 7 with at least one arcuate abutment surface 8. or 9. The figure shows a variant in which both the abutment surface 8 and the abutment surface 9 are arcuate. Otherwise, the shape and size of the jaws 14 and 15 can vary widely within the scope of the present invention. A tool in accordance with the present invention can thereby both be used as a tool with the advantages in accordance with the present invention and also be used as a previously known tool such as a wrench, polygrip or other corresponding tool.
    In alternative embodiments, the adjusting device on the tool may be of an automatic type as marketed by Black & Decker, for example. Alternatively, the adjusting device may consist of another already known adjusting device or in the future developed adjusting device which is suitable for the purpose.
    In alternative embodiments, the abutment surfaces may be provided with transverse grooves (not shown in figures) in one or more directions. It is conceivable, for example, that the contact surfaces are completely or partially lightened.
    It is conceivable that the present invention is only defined as an addition to an existing tool. The invention then consists only of a jaw shown as position 14 or 15.
    Advantages of the Invention With the present invention, a number of advantages are achieved. The most obvious is that one and the same tool can be used for your shapes and dimensions than what it was designed for. Another advantage of the present invention is that worn or damaged tightening surfaces on, for example, nuts, bolts and screws do not prevent them from being loosened or tightened. A further advantage of the present invention is that it reliably and very gently transmits rotating torques to and between objects which are very sensitive to adverse effects. Although certain preferred embodiments have been described in detail, variations and modifications within the scope of the invention may be apparent to those skilled in the art, and all such are considered to fall within the scope of the appended claims. For example, it is conceivable that the present invention may be designed with a locking function such as in a so-called locking shaft or similar construction. It is also conceivable that a tool with at least three jaws would be developed.
