Definitions

  • the invention relates to a screwdriver for hook screws and the like.
  • a shaft for turning the screwdriver is provided on one end face and a radial groove for receiving a screw hook is provided on the opposite, free end face thereof, cf. e.g. DE-U-78 18 746.
  • the hook In conventional hook screws, the hook is provided with a slot for attaching the blade of a screwdriver. Nevertheless, screwing in such hook screws is often tedious, especially since the screwdriver blade can easily slip off the hook. It is known to use a generic screwdriver for screwing in such hook screws, in which the transverse screw hook is more or less positively received by a radial groove of the screwdriver, so that the risk of the screwdriver slipping off the hook screw is largely eliminated.
  • the known screwdrivers of this type are not suitable for screwing in or unscrewing screws provided with an open or closed eyelet, and the object of the invention is to develop a hook screwdriver in such a way that it can also be used for this application.
  • the base body additionally has a diametral groove on the free end face in the form of a circular disk segment for receiving an open or closed screw eyelet. It is expediently provided here that the radial groove and diametrical groove intersect at right angles and open into a T-shaped opening on the free front side of the base body.
  • the base body of the screwdriver according to the invention can be designed in a very inexpensive manner as a relatively small die-cast part. Since the diametral groove is formed in a part of the base body which was not previously used in the known hook screwdrivers, the screwdriver according to the invention can be produced with approximately the same dimensions as the known hook screwdrivers.
  • the screwdriver according to the invention can be used for screws with a circular eyelet, with a flattened eyelet or, as according to the prior art, for hook screws and is distinguished by its increased use due to its more universal usability.
  • the radial groove and the diametral groove are stepped in the direction of depth. This makes it possible to use the screwdriver for hook screws or eyebolts of very different sizes. Further features of the invention are specified in the subclaims and explained in more detail in connection with the following description of the figures.
  • a radial groove 9 with an essentially flat bottom 10 is recessed, and in the bottom 10 of this radial groove a narrower, further radial groove 11 is formed in the center.
  • the radial grooves 9, 11 serve to receive the hooks of hook screws.
  • a diametral groove 12 is excluded from the shape of a circular disk segment, a further, narrower diametral groove 14 being excluded in the center of the circular arc-shaped base 13.
  • the radius of the bottom of this diametral groove 14 is smaller than the radius of the bottom 13 of the diametral groove 9, and the diametral grooves 9, 14 serve to receive the eyelets of eyebolts.
  • the radial grooves 9, 11 are each directed at right angles to the diametral grooves 12, 14, the grooves 9 and 12 opening into a T-shaped opening on the end face 7.
  • the base body 1 is also provided on its shoulder surface 15 with a plurality of recesses 16, 17, 18 to save material.
  • the grooves 9, 11, 12, 14 are closed towards the circumferential surface of the cylindrical base body 1, and the closed groove ends lie on the circumferential surface with marking beads 19.
  • the base body 1 is identical to the embodiment of FIGS. 1 to 6.
  • the shaft 20 here consists of a relatively short hexagonal profile which can be clamped into the chuck of a drill or into the bit holder of a cordless screwdriver or the like.
