  • a first branch 1 having a handle part 2 and a second branch 3 having a handle part 4 are intended to be gripped by an operator.
  • the first branch 1 shows, in the end being most distant from the operator, an holder-on 5, a part 6 for vice attachment, and a former 7.
  • the second branch 3 shows, in the end being most distant from the operator, a link arm 8 and a sliding jaw 9.
  • a first shaft 10 in a corresponding first mounting in the former 7 and/or the link arm 8 pivotably unites the former 7 and the link arm 8.
  • a second shaft 11 in a corresponding second mounting in the link arm 8 and/or the second branch 3 pivotably unites the link arm 8 and the second branch 3.
  • the presence of the shafts 10, 11 means that the first branch 1 is pivotably united to the second branch 3 and that the tool can be manoeuvred by an operator having a branch 1 , 3 in each hand.
  • the branches 1 , 3 are substancially straight except in the handle parts 2, 4 where they, in the ends thereof being closest to the operator, are bent inwards towards each other. This means that the tool is more comfortable to handle in the open state, when the handle parts 2, 4 are far from each other, than the tool would be if the handle parts 2, 4 were straight.
  • the branches 1 , 3 are made of pipes of metal, such as steel or the like, and the pipes also extend substancially through the handle parts 2, 4 but the surface layer of the handle parts 2, 4 consists of a substancially soft elastomer or the like.
  • each one of said pipes instead extends through only a part of the corresponding handle part 2, 4 or not at all extends through the corresponding handle part 2, 4.
  • the two pipes may also be differently long and extend differently far through the respective corresponding handle part, the elastomer or another suitable material making up so that the branches 1 , 3 become substancially equally long.
  • a transport locking device 2a see Figure 5, in the form of a strap that forms at least one loop. If the loop is threaded over the second handle part 4, the handle parts 2, 4 and thereby also the branches 1 , 3 are kept well together during transportation of the tool.
  • the strap of the transport locking device is deflectable and flexible and manufactured from elastic textile, rubber or the like.
  • the holder-on 5 has a curved hook-like shape, see particularly Figures 3 and 4, to be able to retain a pipe 12 in connection with a bending operation. With the concept bending ("bockning") the same as bending (“b ⁇ jning”) is here meant and as a result of the operation, a pipe bend is obtained.
  • the part 6 for vice attachment protrudes from the tool and is provided with two substancially plane- parallel sides 13, 14 suitable for vice attachment.
  • the former 7 has the shape of a modified cylinder segment, the periphery of which has a groove 15 for the receipt of said pipe 12 to be bent.
  • the groove 15 extends alongside said periphery along at least a semicircle in a substancial plane of extension of said modified cylinder segment, which plane of extension is parallel to the plane of the paper in the Figures 2 and 5-7.
  • This semicircle shows a first radius corresponding to the perpendicular distance between the bottom of the groove 15 and the centre of the shaft 10, which first radius should be chosen in view of the dimension of the pipe 12 to be bent, the radius being chosen to be approx. 37-47 mm, preferably approx. 42 mm for pipe dimension 12, and approx. 50-60 mm, preferably approx. 55 mm for pipe dimension 15.
  • said first radius should be smaller than or possibly equal to four times the diameter of the pipe 12. Said first radius corresponds directly to the resulting bending radius of the pipe 12.
  • the groove 15 shows, in a section perpendicular to the substancial length extension thereof, a substancially semicircular shape having a second radius that should correspond to the cross-sectional radius of the pipe 12 and that accordingly also should be chosen in view of the dimension of the pipe 12 to be bent.
  • the entire former 7 is easily replaceable on the tool, and therefore a former having suitable measures of occurring radii can be used for each one of the normally occurring pipe dimensions.
  • the former 7 is fitted to the branch 1 by means of a screw, a pin on the branch 1 simultaneously meeting a corresponding hole in the former 7 to prevent the former 7 from rotating around the screw when the tool is used.
  • the described arrangement is only an example and the corresponding functions may be obtained in any other known way.
  • the web part of the former 7, i.e., the part between the groove 15 and the first shaft 10, is, in comparison with surrounding parts, thin and furthermore broken up with a plurality of through holes 16 of varying shapes.
  • the former 7 is provided with a scale 17 graduated in angular degrees from 0° to 180°, the degree values of 0, 45, 90, 135 and 180 having been marked particularly by the fact that not only scale lines are present for said degree values but also by the fact that the degree values are written numerically. Scale lines and numerals are recessed in the surface of the scale 17 and marked with a colour deviating from the rest of the surface.
  • a pipe-positioning index 18 and a pipe- positioning index 19 are present, which are located along an imaginary, basically straight, line starting from an imaginary extension of the marking for 0° on the scale 17, the pipe-positioning index 18 being located closer than the pipe- positioning index 19 to the marking for 0° on the scale 17, and said line extending substancially parallel to each pipe piece 12 properly placed in the tool in order to be bent.
  • the former 7 also shows five particular overbending indexes 20.
  • an extra handle part/thumb-grip part may be present on the former 7.
  • the sliding jaw 9 is attached to the second branch 3 by two pins 21 of a suitable type, e.g., tension pins 21.
  • the sliding jaw 9 is made of polymer material or the like and provided with a start index 22 and two pipe-positioning indexes 23, 24. Also the sliding jaw 9 shows a groove 25 for the receipt of said pipe 12 to be bent.
  • the groove 25 extends along the entire length of the sliding jaw 9 and shows, in a section perpendicular to the substancial length extension thereof, a substancially semicircular shape having a third radius that should correspond to the cross-section radius of the pipe 12 and that accordingly also should be chosen in view of the dimension of the pipe 12 to be bent. It may also be a modified semicircular shape.
  • the sliding jaw 9 is also easily replaceable on the tool, and therefore a sliding jaw having a suitable measure of occurring radius can be used for each one of the normally occurring pipe dimensions.
  • the holder-on 5, the part 6 for vice attachment, the link arm 8 and the end of the second branch 3, closest to the shaft 11 are manufactured from forged steel or the like.
  • the shafts 10, 11 are manufactured from steel or the like and the former 7 is manufactured from aluminium or the like.
  • the materials mentioned in this description are without exception to be seen as examples.
  • the branches 1 , 3 may, in addition to steel, be made of a number of alternative known materials, such as, for instance, another metal, light metal, composite and/or plastic, and the same applies to the holder-on 5, the part 6 for vice attachment, the link arm 8 and the shafts 10, 11.
  • the former 7 may, in addition to aluminium, be made of a number of alternative known materials, such as, for instance, another light metal, metal, composite and/or plastic.
  • the sliding jaw 9 may, in addition to polymer material, be made of a number of alternative known materials, such as, for instance, metal, ceramic and/or composite.
  • the pipe 12 suitably in the form of a pipe piece 12 having an index for a bending measure of the pipe bend intended to be produced, is placed in the tool in such a way that the pipe 12 will rest in the groove 15 and simultaneously be positioned in the holder-on 5 in the hook-shaped end part thereof.
  • Said bending measure constitutes, for the pipe bend intended to be produced and as for a bending of approx.
  • a plane substancially coincident with a substancially straight centre line here is meant a plane that intersects the centre line and simultaneously extends substancially parallel to the same, i.e., the centre line lies entirely in the plane.
  • centre line here is meant a line that interconnects the circle centres in each cross-section of the pipe 12.
  • the proper bending of the pipe 12 is carried out, the operator bringing together the branches 1 , 3 using a greater force in a continuous motion, the sliding jaw 9 sliding on the pipe 12 and pressing the same against the former 7 until the desired bending angle has been attained.
  • the attained bending angle is given by the degree-value marking on the scale 17 where the start index 22 on the sliding jaw 9 is.
  • overbending indexes 20 will be useful, which mark overbending by 3, 6, 9, 12 and 15° over 90° respectively.
  • angular degree values are the ones preferred, but overbending indexes in the intervals of approx. 1-3 and/or approx. 4-6 and/or approx. 7-9 and/or approx. 10-12 and/or approx. 13-15° over 45°, or over any other degree value, are also possible.
  • the tool according to the invention shows, among other things, the following advantages.
  • the handle parts 2, 4 are patterned and made with large diameter and bent shape to afford the operator a good grip.
  • the branches 1 , 3 are longer than usual, so that less force than usual should be needed upon bending. Occurring start and pipe-positioning indexes on the former 7 and the sliding jaw 9 and a large opening between the former 7 and the holder-on 5 makes it easy to quickly place the pipe 12 to be bent in the proper position.
  • the sliding jaw 9 is of polymer material, the pipe 12 is not scratched upon bending.
  • the scale 17 is easily read since the markings and the numerals are clearly made, recessed and have a deviating colour, and the same applies to occurring start, pipe-positioning and overbending indexes on the former 7 and the sliding jaw 9.
  • the special part 6 for vice attachment means a simple mounting in this way.
  • the particular transport locking device 2a facilitates transportation and storing of the tool.
