Definitions

  • the invention relates to an adjustable ring wrench according to the preamble of claim 1.
  • the tongue is held on the shaft element by means of bolts which protrude from the tongue through a slot in the shaft element and rest on the back with its head.
  • bolts which protrude from the tongue through a slot in the shaft element and rest on the back with its head.
  • the force that can be applied to the nut to be loosened or tightened is relatively low, since the tongue is very flat and the nut engages in an equally flat or narrow area. When a greater force is applied, the mother is then destroyed.
  • the invention has for its object to develop an adjustable ring wrench of the type mentioned in such a way that the forces that can be applied are increased and the handling of the arrangement is improved.
  • This object is achieved in that the tongue is held displaceably in the region of the key ring by means of a cross band on the shaft element.
  • This type of attachment ensures that the tongue is effectively secured exactly at the point where the greatest force, which is perpendicular to its flat side, is effectively secured and therefore cannot break out upwards.
  • the tongue preferably has a thickened region at its end which can be inserted into the key ring, the thickness of which corresponds to that of the key ring. This measure ensures that the gripping surface of the key ring and tongue are of the same size, so that damage to the nut only occurs with significantly higher forces (if any).
  • key rings of different grip widths are provided on both ends of the shaft element, so that the entire arrangement covers a further adjustment range without having to use a very narrow tongue.
  • transverse bands are provided at both ends of the shaft element.
  • the manufacture of the ring wrench can be simplified and the durability can be improved that one of the two transverse bands is welded to the shaft element, while the other transverse band can be subsequently attached to the shaft element.
  • this cross band is non-detachably held at one end by a bolt with the shaft element, but parallel to its surface and parallel to the surface of the tongue, while a screw is used for attachment at the other end.
  • the tongue is then pushed under the fixed transverse band, laid flat on the shaft element and finally the other transverse band is pivoted back and screwed on after pivoting the one transverse band.
  • the ring wrench is then particularly easy to handle and is particularly similar to a "normal" ring wrench in terms of use if its back is flat. Furthermore, the usability of the arrangement with a key ring at each end is improved by the fact that the worm drive in the The middle of the shaft element is attached, because the "grip feeling" is then particularly good.
  • a lubrication and cleaning hole is preferably provided in the tongue and / or in the shaft element.
  • this is of particular advantage, in particular in combination with the manner in which the tongue is held on the shaft element. It has been shown that the known adjustable ring wrench gets dirty very quickly and to an extent that its adjustability suffers considerably. This is not the case with the ring wrench according to the invention.
  • the adjustable ring wrench has a flat shaft element 10 which has a groove with limiting rails 11, 12 over its entire length. Key rings 20, 20 'are formed at both ends of the shaft element 10, the two key rings 20, 20' having different dimensions from one another.
  • a tongue 14 is mounted in the groove in the shaft element 10.
  • the tongue 14 has end sections shaped in such a way that it continues the contour of the left, larger key ring 20 in the position drawn to the right in FIG. 1, while in the position shifted to the far left (in FIG. 1) in the smaller key ring 20 'whose largest opening width is defined.
  • a worm 31 is rotatably mounted on the one limiting rail 12 or on the shaft element 10, specifically in the middle thereof, and engages with a toothing 32.
  • the tongue 14 can be shifted to the left and to the right via the worm drive 30 thus formed.
  • a transverse band 21, 21' In the area of the key rings 20, 20 ', a transverse band 21, 21', the tongue 14 covering the shaft element 10 or the limiting rails 11, 12 is attached.
  • the one cross belt 21 ' is welded here, while the other cross belt 21 is fixed at one end by a bolt 22, at the other end by a releasable screw 23 is.
  • the bolt 22 is designed so that the cross belt 21 can be pivoted after loosening the screw 23 and so the tongue 14 can be pulled out obliquely above the other cross belt 21 '.
  • the tongue 14 has at its ends a thickened area 14 ', 14 ⁇ , which projects so far down over the tongue 14 (in Fig. 3) that its thickness corresponds to that of the key ring 20 or 20'. Accordingly, a recess 10 'or 10' is provided in the underside 13 of the shaft element 10, which preferably protrudes so deeply into the shaft element that the tongue 14 is guided on its underside just as far perpendicular to its flat side as on its upper side by the respective cross belt 21, 21 '.
  • the underside 13 of the shaft element 10 is flat.
  • a lubrication and cleaning bore 15 is provided in the tongue 14, and a lubrication bore 16 in the underside 13 of the shaft element.
