Definitions

  • the invention relates to a pocket screwdriver with bits magazine and clip, in which an assortment of bit inserts is accommodated in the handle and which is equipped with a clip for connection.
  • Such pocket screwdrivers can always be carried by the user, such as a voltage tester screwdriver or pen, secured against loss by the clip, so that the tool is always at hand with a variety of different tool inserts.
  • the object of the invention is to provide a universally usable pocket screwdriver with clip and magazine for a large number of interchangeable tools insert, so-called bits, in which both the exchange is convenient and quick and also makes it easier to find the required use, and that relatively high torques can also be applied due to the size and shape of the handle when the shape of the handle is ergonomically adapted .
  • the universal usability of the subject of the invention both in the longitudinal direction and in an angular version is achieved in that an insertion opening in the tool booklet for the tool inserts is provided, one starting from its end face and the other in the transverse direction.
  • the design or arrangement of a clip for attaching to pockets of clothing or the like can, depending on the most favorable conditions of the manufacturing company, as one in the transverse direction horizontal insertion opening for the tool inserts, which can be used and locked, or selected as a single piece with the handle or as an attached part.
  • the drawers are only of one length for a tool set and are present between these webs in the booklet, preferably three drawers in the longitudinal direction thereof for two tool inserts to be inserted next to each other.
  • the advantages achieved by the invention are, in particular, that due to the proposed shape of the tool handle of the pocket screwdriver, namely its square and thinned shape, a relatively high screwing torque can be expended with a particularly favorable, hand-protecting, ergonomic shape, this pocket screwdriver is to be used universally as a straight and angled screwing tool and the different tool inserts are stored so that they are clearly recognizable and cannot be lost, so that such a tool can be used by several types of bits, e.g. up to 6 pieces, always at hand and it is fully suitable for hobbyists as well as for professional purposes.
  • FIG. 1 is a sectional view taken along the line A-B of FIG. 2,
  • FIG. 2 is a plan view of FIG. 1 in the direction of arrow Z, 3 shows a cross section along the line CD of FIG. 1,
  • FIG. 4 shows an end part corresponding to FIG. 2, but with a clip inserted
  • FIG. 6 is a sectional view along the line E-F of FIG. 5,
  • Fig. 7 in partial view an embodiment with a clip.
  • a pocket screwdriver with bits magazine and clip 1 according to FIGS. 1-3 has a square tool handle 2 with rounded edges 3 and shape 4 gradually thinning towards the center, in which three openings 5 for inserting bits tool inserts 9 receiving drawers 6 or 7 are provided.
  • the drawers 6 and 7 boxes 8 for inserting the bits tool inserts 9 or similar tool parts are designed so that the latter can be used with little play, so that there is no excessive rattling noise during the transport movements of the pocket screwdriver.
  • the drawers can be made of relatively soft material.
  • the drawers 6. 7 are preferably made of transparent material so that the user can see the inserted bits tool inserts 9 from the outside. They can also be designed as parts tinted differently in color, so that this provides the user with further support in recognizing the respective bit tool insert. It can also be expedient to image the internal bits tool inserts 9 on the outside of the drawers 6 and 7, preferably not washable.
  • the openings 5 are partitioned off by webs 15, and this increases the stability of the tool booklet 2 with respect to the bending stress and the indentation.
  • the drawers 6 and 7 are fitted into the openings 5 with little play; a dimension 25 from the upper edge of the bit tool insert 9 to the inner surface of the opening 5 can also be kept correspondingly small for the almost play-free storage of the bit tool insert 9, e.g. 0.2 - 0.4 mm, so that they do not cause high noises in the movements of the subject of the invention in this respect either.
  • the two bits-tool inserts 9 are each to be inserted from the opposite side, whereas in the drawer 7 this is done from one side.
  • An insertion opening 18 extends from an end face 17 into the tool handle 2 and has a mating coupling profile corresponding to a hexagon of the bits tool inserts 9. Following this coupling part, a magnet 19 for the system and thus for holding the bits tool inserts 9 in the inserted state is firmly inserted into the tool booklet 2.
  • a can be inserted in the front area of the insertion opening 18 Detonating or an O-ring 20 can be used, which engages in grooves 21 of the bits tool inserts 9 known per se.
  • an explosive or O-ring 20 also being provided for holding.
  • a clip 27 is inserted into the insertion opening 18, which has thin, elastic lip rings 29 and / or elastic inserts 30 for a firm hold on its hexagon piece 28, the end face of which rests on the coupling surfaces of the insertion opening 18.
  • Such inserts 30 can also be used in the tool booklet 2 in the area of the coupling surfaces.
  • the means for additionally holding the clips are only to be chosen so effectively that they can be used under comfortably exerted pressure and can also be removed by hand with reasonable effort if necessary.
  • the clip bracket 26 protrudes laterally in the area of the insert 31 opposite the latter with bevelled surfaces 32.
  • a clip 33 can also be made in one piece with a tool booklet 2a or attached to it in another way, e.g. by welding, riveting or the like.
  • the hold for the bits-tool inserts 9 can also be achieved in an insertion opening 18 a according to FIG. 5 only or additionally by a magnet 34 inserted in the handle 2 a.
  • a clip 35 as shown in FIG. 7, is fixedly attached with a holding part 36 to a square extension 37 of the handle 2 b, the holding part 36 in the area of the insertion opening for the bits tool insert 9 providing adequate space.

Abstract

Cet outil (1) permet à l'utilisateur de travailler sur différents types de vis sans avoir à emporter avec lui un important assortiment d'outils. Pour pouvoir utiliser rapidement et commodément, sans avoir à les chercher, un nombre relativement élevé de lames amovibles (2), par exemple six, et avoir la possibilité d'appliquer sans difficultés la force nécessaire dans chaque cas, le manche (3) de l'outil a une forme carrée et comporte une partie centrale légèrement plus mince dans laquelle sont disposés des tiroirs (4) destinés à recevoir chacun deux lames (2).
