Definitions

  • the invention relates to a tool equipped with a blade and a handle, in particular a screwdriver, with compartments for screw inserts or the like provided at the top of the handle, which compartments can be closed by a common cover.
  • the object of the invention is to design a generic tool with a simple construction in terms of manufacturing technology.
  • a generic tool of in particular increased utility value is achieved: if the screw inserts etc. are still stored in the most economical way, the joint that closes the compartments is releasable and assignable.
  • a snap-in connection is used. This is centrally oriented.
  • the cover which acts like a protective cap, forms a pressure plate that lies comfortably in the hand and, due to its free rotatability in the plug-lock connection axis, avoids friction in the palm of the operating hand.
  • the locking forces are set so that the compartments are accessible by simply pulling off the cover, but on the other hand there is sufficient captivity.
  • the plug-in snap-in connection consists of a pin with a spring ring spanned thereon, which, even in the expanded state, lies freely rotatable in a groove which is arranged in the wall of the pin-receiving cavity of the cover.
  • a type of releasable coupling also leaves enough play so that even slight tilting movements of the cover can be compensated for.
  • the spring ring is round and the pin has a hexagonal cross section with at least corner notches. The corresponding round cross-section of the spring washer favors sliding into the locking position or lifting the locking connection.
  • the hexagonal cross section of the pin there are evenly distributed locking zones on the circumference thereof.
  • the tool shank which usually has a hexagonal cross section, can be pulled through the stapling body to form the pin, right up to the region of the cover bearing.
  • an advantageous embodiment is achieved by means of a dial rotatably mounted on the pin, with a removal hole which can be rotated via a compartment in each case and with throats provided on the upper side, which extend into the peripheral surface.
  • the dial With regard to the storage of the dial, it is advantageous that it is axially fixed by a spring ring which lies in a central throat of the dial and is overlaid from the bottom of a pot-shaped recess on the underside of the cover.
  • a particularly wear-resistant rotary bearing of the lid in the snap-plug connection is realized in that the groove is arranged in a metal bushing which is seated in the plastic lid and which forms the pin-receiving cavity. Such a metal can lining the cavity can be easily incorporated when the cover is sprayed.
  • the tool which is designed as a screwdriver, has a handle 2 with axially arranged recessed grips 1 to achieve a so-called "Kraftform" handle.
  • compartments 3 oriented in a uniform angular distribution parallel to the longitudinal central axis x-x of the tool are taken into account.
  • the latter form a magazine for receiving screw inserts 4, so-called bits.
  • the compartments 3 are comparable to bores.
  • the relevant binding end consists of transparent material and is secured to the rest of the binding body against rotation.
  • the screw inserts 4 have heads 5 of different designs, for example in the context of the so-called cross recess. Standard flat blades etc. can also be part of the range.
  • the inserts 4 can be assigned to a chuck 7 seated at the free end of the tool shank 6, which is hexagonal in cross section.
  • the compartments 3 are covered with a cover 9 with the interposition of a dial 8.
  • the relatively thin-walled dial 8 is mounted centrally and has a removal hole 10 which can be brought into congruent alignment with the cross sections of the compartments 3. With a correspondingly congruent position of the hole 10, the selected screw insert 4 can, of course, be released after the cover 9 has been removed. By inserting a finger into the removal hole 10, the dial 8 can be rotated like that of a telephone.
  • the cover 9 is detachably held on the booklet 2 by means of a plug-and-snap connection and can be freely rotated about its central plug-and-snap connection axis, which coincides with the longitudinal central axis xx of the screwdriver.
  • Part of the plug-in snap-in connection is a top stapling de, so subjects 3 and dial 8 projecting pin 11.
  • the latter is molded centrally into the staple body and, depending on the basic version of the tool, can continue without interruption in the tool shank 6. In the exemplary embodiment, however, a separate assignment of the pin 11 is preferred.
  • the detent-imparting body is an open spring ring 12 which, even in the expanded state, lies freely rotatably in a groove 13 in the wall 14 of the receiving cavity 15 of the cover 9. It acts like the female part of a push button, the male part of which is the pin 11.
  • the spring ring 12 has a circular cross-section and, overlapping the joint F, projects into the corner-side locking notches 16 of the pin 11, which is hexagonal in cross-section and a half entry into the locking notches 16.
  • Their end notch inlets have an approximately 45 ° beveled flank 16 'or 16 ⁇ .
  • the flank 16 'further away carries the end of the booklet.
  • the other, 16 ⁇ is approximately twice the diameter of the spring ring 12 corresponding distance to the other.
  • the groove 13, on the other hand, has parallel, horizontal flanks 13 'and 13 ⁇ .
  • the axially measured width of the groove is somewhat larger than the cross-sectional diameter of the spring ring 12.
  • the groove depth is larger than the cross-sectional diameter of the spring ring 12, so that it can deflect into the plane of the wall 14.
  • the dial 8 arranged below the removable cover 9 is also rotatably mounted using the same pin 11 and axially fixed by a spring ring 17.
  • This spring is in an upwardly open, axial throat 18 of the dial 8. It is a through to a central turntable opening 19 knife larger turn.
  • the axial depth is greater than the cross-sectional diameter of this spring ring 17, which directly overlaps the horizontal turning shoulder 20.
  • the spring ring 17 is axially held in locking notches 21. These are adapted to the contour of the inserted spring cross section.
  • the dial 8 forms a relatively flat cup-shaped depression 22 on its underside, so that the pin-receiving cavity 15 attaches to the flat underside 9 'of the cover 9 in a distance region.
  • the relevant bottom of the pot-shaped recess has the reference numeral 22 '.
  • the pin receiving cavity 15 is lined. It is a cup-shaped metal sleeve 23. For safe injection anchoring, its outer surface forms an annular groove 24 in the upper half of the metal sleeve 23.
  • the bottom or rather the ceiling 25 of the cup-shaped metal sleeve 23 has a greater thickness than the wall of the sleeve. In adaptation to the chamfer 11 'of the pin 11, the bottom runs out into a centrally oriented conical trough, taking into account the chamfer angle.
  • the dial 8 has on its top in the peripheral surface 8 ⁇ of the dial 8 throats 26 (see Figures 2 and 4). Using these throats, it is relatively easy to pry off the lid, for example by moving a fingertip into the area of the throat 26 or using and tilting a blade-like tool. In contrast, accidental touches cannot be converted into an opening movement due to the lack of a corresponding contact surface.
  • the sickle or lenticular throats as a turning aid. For example, fingers smeared with fat cannot slip off. Rather, there is a crown-like edge roughening for rotating the dial, unless the dial-type handling explained above is preferred.
  • the handling is, briefly summarized, as follows: To remove a screw insert, the cover 9 is removed from the pin 11 while overcoming the locking forces captivating it. As a result, the dial 8 is exposed. Your removal hole 10 is moved into the desired position previously selected based on the transparency of the magazine. After congruent alignment of the hole and the tray, the tool only needs to be tilted in the sense of being poured out. The remaining screw inserts 4 are locked against slipping out. After putting the lid back on, the ergonomically favorable basic shape of the stapling body is again present, since the lid 9 has a domed top 9 ⁇ , so that the appropriately dome-shaped end section lies well in the hand and can thus also act as a pressure plate.
