Definitions

  • the invention relates to a screwing tool for tightening and loosening screws according to the preamble of claim 1.
  • Screwing tools of the type mentioned here have a blade and a trained as a polygonal working end. This passes over a constriction area and a transition area in the blade.
  • the tools are used to tighten and loosen screws. Characterized in that between the working end and the transition region a constriction region is formed, a ball head is quasi formed, which engages in the head of a screw.
  • This can be designed for example as a Torx screw. Due to the constriction, it is possible not only to arrange the screwing tool perpendicular to the screw head, ie in extension to the axis of rotation of the screw, but at an angle thereto. This facilitates the tightening and loosening of screws in poorly accessible areas. It has been found that the working end can be turned off by the constriction area, as a result of which the screwing tool becomes unusable.
  • the object of the invention is therefore to provide a screwing tool for tightening and loosening of screws, which does not have this disadvantage.
  • a screwing tool for tightening and loosening of screws which avoids this disadvantage. It has a handle, a blade and a trained as a polygonal working end. The between the end of work and the Blade lying portion includes a immediately adjacent to the working end neck area and a transition area. The tool is characterized in that the transition region is also formed as a polygon. It is provided that the outer contour of the transition region and that of the working end are substantially identical. If too high torques are applied with the screwing tool, the working end tears off in the constriction area. Since the transition region has the same outer contour as the working end, this can continue to be used for tightening and loosening screws. The screwing tool is not completely useless.
  • a preferred exemplary embodiment of the screwing tool is characterized in that a circumference around the working end has the same diameter as a circumference around the transitional area.
  • the working end and the transition area can therefore be used for the same screw type. That is, a working end is designed for example on an 8 mm screw, so the transition area is just right for these screws. If, therefore, there is a marking on the screwing tool which indicates the associated screw type, no problems arise for the user of the screwing tool if the working end breaks off because it can still be used for the same screw type.
  • the constriction area is designed such that the end of the transitional area facing this has a chamfer which tapers towards the working end. So the end of work should be due to an overload of the screwdriver Tool be turned off, so this chamfer acts as Ein Industriesfase for the screwing, which facilitates the insertion of the transition region in a screw head.
  • the outer contour of the working end and the transition region are tuned to Torx screws.
  • the blade is rotatably connected to a handle.
  • an embodiment of the screwing tool is particularly preferred in which the working end, the necking, the transition region and the blade are formed as a bit. This screwing tool can then be used in the recording of a screwdriver.
  • Figure 1 is a perspective view of the front end of a
  • Figure 2 is a perspective view of the screwing tool with turned off working end.
  • Figure 1 shows a perspective view of the front end of a screw 1. It includes a working end 3, which is designed as a polygon. It has a main body 5, in which, by way of example, six in the direction of a longitudinal axis 7 of the screw Tool 1 extending recesses 9, between which six projections 11 are formed accordingly.
  • the recesses 9 and the projections 11 are each formed identically so that they need not be explained individually.
  • the projections 11 of the working end 3 go over an arc 13 in the end face 15 of the working end 3 over. At the working end 3 is followed by a constriction area 17 to the right. In these, the projections pass over a curved region 19. It can be seen that the arc 13 continuously merges into the region of curvature 19, so that the outer contour of the projections 11 is curved as a whole.
  • the working end 3 thus forms a screw head. It is thereby possible to introduce the working end 3 in the head of a screw which is provided with a corresponding recess whose inner contour corresponds to the outer contour of the working end 3.
  • the screwing tool 1 can not only be arranged in alignment with the screw axis, so that therefore the longitudinal axis 7 of the screwing tool is aligned with the screwing axis. Rather, it is possible to arrange the longitudinal axis 7 at an angle relative to the screw axis.
  • a transition region 21 is provided on the working end 3 side facing away from the constriction region 17. This passes through a step 23 in a blade 25, whose outer contour is preferably formed as a polygon, in particular as a hexagon.
  • the working end 3, the constriction region 17, the transition region 21 and the blade 25 are integrally formed.
  • the working end 3, the necking region 7 and the transition region 21 are preferably produced in a cold forming process.
  • the outer contour in the transition region 21 coincides with the outer contour of the working end 3. That is, in the peripheral surface of the transition region 27 recesses 29 are introduced, between which projections 31 are located.
  • the coincidence of the outer contour of the working end 3 and the transition region 21 is that the number of recesses and projections is the same.
  • a projection 11 of the working end 3 continues in a projection 31 of the transition region 21. Accordingly, a recess 9 continues in the working end 3 in a recess 29 in the transition region 21.
  • an imaginary circumference around the working end 3 has the same diameter as a circumference around the transitional region 21.
  • the constriction region 17 is formed such that a chamfer 35 is formed at the end 33 of the transitional region 21 facing the constriction region 17. That is, the outer contour of the transition region 21 tapers conically in the direction of the working end 3 to the bottom 37 of the constriction region 17, that is to say, where the constriction region 17 has the smallest outside diameter.
  • the outer contour of the working end 3 and the outer contour of the transitional region 21 are configured such that they coincide with the inner contour of a Torx screw.
  • the screwing tool 1 shown in FIG. 1 is a bit which holds the working end 3, the necking rich 17, the transition region 21 and the blade 25 includes.
  • Such a bit can be inserted in known manner in a receptacle of a screwing tool with a handle, which serves to manually tighten and loosen screws. It is also conceivable, however, to use wine such a bit in a screwing, which attracts and dissolves with engine power screws.
  • FIG. 2 shows the screwing tool 1 with the blade 25 and the transition region 21.
  • the same parts are provided with the same reference numerals, so reference is made in this regard to the description of Figure 1.
  • the illustration according to FIG. 2 shows that the working end 3 of the screwing tool has been torn off. This can be done, for example, that too high torque on the blade 25, the transition region 21, the constriction region 17 and the working end 3 acts either when loosening seized screws or too tight tightening screws.
  • the working end 3 can also be deliberately turned off if the projections 11 of the working end 3 are worn out due to frequent use.
  • the tool 1 is characterized in that the constriction region 17 is specially designed. It is so thin in the region of the reason 37, thus has such a small outer diameter, that the working end 3 is turned off at a certain maximum torque just here in the area of the bottom 37 or breaks off.
  • the chamfer 35 remains at the end 33 remote from the blade 25. Since the outer contour of the transitional region 21 coincides with that of the working end 3, the transition region 21 can now be used for tightening and loosening screws by the transition region 21 in FIG the corresponding recesses in the head of screws is inserted.
  • the chamfer 35 serves as Einriosfase and thus facilitates the use of the screwing.
  • the screwing tool can be used for tightening and loosening certain screws, either with the working end 3 or after tearing it off with the transition region 21. Both times one and the same screwing tool 1 can be used for tightening and loosening the same screws.
  • constriction region 17 in particular the dimensioning of the base 37, causes the working end 3 to be twisted or torn so that the transition region 21 remains intact and the screwing tool 1 remains usable, whether it is designed as a bit or that it is realized as a normal screwdriver with a handle.
  • the tearing off of a working end 3 does not therefore mean a total loss for a user.
