Description

Die Erfindung betrifft ein mit Klinge und Heft ausgestatte­tes Werkzeug, insbesondere Schraubendreher, mit am oberen Heftende vorgesehenen Fächern für Schraubeinsätze oder der­gleichen, welche Fächer von einem gemeinsamen Deckel ver­schließbar sind.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.

Es ist bekannt, den Deckel zur Zugänglichkeit der Fächer wegzuschwenken. Hierzu ist er exzentrisch gelagert. Da über das freie Ende des Heftes beim Einziehen von Schrauben oder dergleichen Druckkräfte eingeleitet werden, kann der Deckel sich verlagern und ungünstigstenfalls sogar abbrechen.It is known to swing the lid away for access to the compartments. For this purpose, it is mounted eccentrically. Since compressive forces are introduced via the free end of the booklet when screws or the like are pulled in, the cover can shift and, in the worst case, even break off.

Aufgabe der Erfindung ist es, ein gattungsgemäßes Werkzeug bei herstellungstechnisch einfachem Aufbau handhabungsgünsti­ger auszubilden.The object of the invention is to design a generic tool with a simple construction in terms of manufacturing technology.

Gelöst ist diese Aufgabe durch die im Anspruch 1 angegebene Erfindung.This object is achieved by the invention specified in claim 1.

Die Unteransprüche sind vorteilhafte Weiterbildungen des erfindungsgemäßen Werkzeuges.The subclaims are advantageous developments of the tool according to the invention.

Zufolge solcher Ausgestaltung ist ein gattungsgemäßes Werk­zeug von insbesondere erhöhtem Gebrauchswert erzielt: Bei weiterhin günstigst erreichter Magazinierung der Schraubein­sätze etc. ist der die Fächer gemeinsam verschließende Dek­ kel bequem lös- und zuordbar. Hierzu kommt eine Steck-­Rastverbindung zur Anwendung. Diese ist zentral orientiert. Der wie eine Schutzkappe wirkende Deckel bildet dabei quasi eine Druckplatte, die gut in der Hand liegt und zufolge ihrer freien Drehbarkeit in der Steck-Rast-Verbindungs­achse Reibungen im Handteller der Bedienungshand vermeidet. Die Rastkräfte sind so eingestellt, daß durch einfaches Abziehen des Deckels die Fächer zugänglich werden, anderer­seits aber die genügende Unverlierbarkeit gegeben ist. Kon­kret besteht die Steck-Rastverbindung aus einem Zapfen mit darauf aufgespengtem Federring, welcher auch im aufgeweite­ten Zustand frei drehbar in einer Nut einliegt, die in der Wand der Zapfen-Aufnahmehöhlung des Deckels angeordnet ist. Eine solche Art der lösbaren Kupplung läßt auch genügend Spiel, so daß sogar ggf. leichte Kippbewegungen des Deckels kompensiert werden. Weiter erweist es sich als vorteilhaft, daß der Federring runden und der Zapfen sechseckigen Quer­schnitt besitzt mit mindestens eckseitigen Rastkerben. Der entsprechende Rund-Querschnitt des Federringes begünstigt das Aufgleiten in die Rastposition bzw. das Aufheben der Rastverbindung. Hinsichtlich des hexagonalen Querschnitts des Zapfens ergeben sich am Umfang desselben gleichmäßig verteilte Rastzonen. Außerdem kann der meist sechseckigen Querschnitt aufweisende Werkzeugschaft zur Bildung des Zap­fens durch den Heftkörper durchgezogen sein bis in den Be­reich der Deckellagerung. Um beispielsweise auszuschließen, daß bei Deckelabzug gleich sämtliche Fächer zugänglich offen liegen, ist eine vorteilhafte Ausgestaltung erzielt durch eine auf dem Zapfen drehbar gelagerte Wählscheibe mit einem jeweils über ein Fach drehbarem Entnahmeloch und mit an der Oberseite vorgesehenen Kehlen, die bis in die Umfangsfläche reichen. Zufolge der Zwischenschaltung einer solchen Wähl­scheibe wird das Loch in kongruente Lage mit dem ausgewähl­ten Fach gebracht. Durch Stürzen des nach unten gerichteten Heftes kann so der entsprechende Schraubeinsatz aus dem Magazin herausrutschen. Die an der Oberseite der Wählscheibe vorgesehenen Kehlen gestalten die Wählscheibe griffig. Sie läßt sich daher auch bei fettverschmierter Bedienungshand schlupffrei drehen. Da die Kehlen bis zur Umfangsfläche lau­fen, ist die Fuge erweitert, so daß man mit der Fingerkuppe dort eingreifen und den Deckel bequem absprengen kann. Hin­sichtlich der Lagerung der Wählscheibe ist es von Vorteil, daß diese von einem Federring axial fixiert ist, der in einer zentralen Kehle der Wählscheibe einliegt und überfan­gen ist vom Boden einer topfförmigen Vertiefung an der Unter­seite des Deckels. Eine vor allem verschleißfeste Drehlage­rung des in Rast-Steckverbindung stehenden Deckels ist da­durch realisiert, daß die Nut in einer in dem aus Kunststoff bestehenden Deckel einsitzenden Metallbüchse angeordnet ist, welche die Zapfen-Aufnahmehölung formt. Eine solche die Höhlung ausfütternde Metallbüchse läßt sich beim Spritzen des Deckels einfachst einverleiben.As a result of such an embodiment, 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. For this purpose, 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. Specifically, 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. Such a type of releasable coupling also leaves enough play so that even slight tilting movements of the cover can be compensated for. It also proves to be advantageous that 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. With regard to the hexagonal cross section of the pin, there are evenly distributed locking zones on the circumference thereof. In addition, 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. In order to rule out, for example, that all compartments are immediately accessible when the cover is removed, 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. As a result of the interposition of such a dial, the hole is brought into a congruent position with the selected compartment. The corresponding screw insert can slip out of the magazine by falling down the handle. The grooves provided on the top of the dial make the dial easy to grip. they can therefore be turned without slippage even with greasy operating hands. Since the throats run up to the circumferential surface, the joint is widened so that you can intervene there with your fingertip and easily detach the lid. 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.

Das als Schraubendreher ausgebildete Werkzeug besitzt ein mit axial hintereinanderliegenden Griffmulden 1 ausgestatte­tes Heft 2 zur Erzielung eines sogenannten "Kraftform"-­Griffes.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.

Vom oberen Heftende her sind in gleichmäßiger Winkelvertei­lung raumparallel zur Längsmittelachse x-x des Werkzeuges orientierte Fächer 3 berücksichtigt. Letztere bilden ein Magazin zur Aufnahme von Schraubeinsätzen 4, sogenannte Bits. Die Fächer 3 sind Bohrungen vergleichbar. Das diesbe­zügliche Heftende besteht aus Klarsichtmaterial und ist am restlichen Heftkörper gegen Drehung gesichert befestigt.From the top of the booklet, 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.

Die Schraubeinsätze 4 weisen unterschiedlich gestaltete Köpfe 5 auf, beispielsweise im Rahmen der sogenannten Kreuz­schlitzung. Auch übliche Flachklingen etc. können zum Sorti­ment gehören. Die Einsätze 4 lassen sich einem am freien Ende des in Querschnitt hexagonalen Werkzeugschaftes 6 sit­zenden Spannfutter 7 zuordnen.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.

Die Fächer 3 sind, unter Zwischenlage einer Wählscheibe 8, von einem Deckel 9 überfangen.The compartments 3 are covered with a cover 9 with the interposition of a dial 8.

Die relativ dünnwandige Wählscheibe 8 ist zentral gelagert und weist ein in deckungsgleiche Ausrichtung zu den Quer­schnitten der Fächer 3 bringbares Entnahmeloch 10 auf. Bei entsprechend kongruenter Lage des Loches 10 wird der ausge­wählte Schraubeinsatz 4, nach vorherigem Entfernen des Dek­kels 9 natürlich, freigebbar. Durch Einsetzen eines Fingers in das Entnahmeloch 10 läßt sich die Wählscheibe 8 wie die eines Telefons drehen.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.

Der Deckel 9 ist über eine Steck-Rastverbindung am Heft 2 lösbar gehalten und um seine zentral liegende Steck-Rast­Verbindungsachse, die mit der Längsmittelachse x-x des Schraubendrehers zusammenfällt, frei drehbar. Bestandteil der besagten Steck-Rastverbindung ist ein das obere Heften­ de, also Fächer 3 und Wählscheibe 8 überragender Zapfen 11. Letzterer ist dem Heftkörper zentral eingeformt und kann sich, je nach Grundversion des Werkzeuges, unterbrechungs­frei in den Werkzeugschaft 6 fortsetzen. Beim Ausführungsbei­spiel ist jedoch eine getrennte Zuordnung des Zapfens 11 bevorzugt.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.

Der rastvermittelnde Körper ist ein offener Federring 12, der auch in aufgeweitetem Zustand frei drehbar in einer Nut 13 in der Wand 14 der Aufnahmehöhlung 15 des Deckels 9 ein­liegt. Sie wirkt wie das Matrizenteil eines Druckknopfes, dessen Patrizenteil der Zapfen 11 ist.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.

Der Federring 12 weist kreisrunden Querschnitt auf und ragt, die Fuge F übergreifend, in eckseitige Rastkerben 16 des im Querschnitt sechseckigen Zapfens 11. Die einer schwimmenden Einlagerung vergleichbare Zuordnung des Federinges 12 berück­sichtigt, bezogen auf die Fuge F, einen hälftigen Eintritt in die Nut 13 und einen hälftigen Eintritt in die Rastkerben 16. Ihre endseitigen Kerbeneinläufe besitzen eine etwa 45° geschrägte Flanke 16′ bzw. 16˝. Beim Ausführungsbeispiel trägt die dem Heftende weiter entfernte Flanke 16′. Die andere, 16˝, liegt in einem etwa dem 2-fachen Durchmesser des Federringes 12 entsprechenden Abstand zur anderen. Die Nut 13 weist dagegen parallelverlaufende, horizontale Flan­ken 13′ und 13˝ auf. Die in der axialen gemessene Breite der Nut ist etwas größer als der Querschnittsdurchmesser des Federringes 12. Die Nuttiefe ist dagegen größer als der Querschnittsdurchmesser des Federringes 12, so daß er bis in die Ebene der Wand 14 ausweichen kann.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˝. In the embodiment, 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, however, is larger than the cross-sectional diameter of the spring ring 12, so that it can deflect into the plane of the wall 14.

Auch die unterhalb des abnehmbaren Deckels 9 angeordnete Wählscheibe 8 ist unter Nutzung des gleichen Zapfens 11 drehbar gelagert und durch einen Federring 17 axial fixiert. Dieser Federing liegt in einer nach oben offenen, axialen Kehle 18 der Wählscheibe 8 ein. Es handelt sich um eine an eine Drehscheiben-Zentralöffnung 19 anschließende, im Durch­ messer größere Ausdrehung. Die axiale Tiefe ist größer als der Querschnittsdurchmesser dieses Federringes 17, der die horizontale Ausdrehungsschulter 20 unmittelbar überlagert. Seinen axialen Halt findet der Federing 17 in Rastkerben 21. Diese sind der Kontur des einliegenden Federquerschnitts angepaßt.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.

Oberhalb der Kehle 18 bildet die Wählscheibe 8 an ihrer Unterseite eine relativ flache topfförmige Vertiefung 22 aus, so daß die Zapfen-Aufnahmehöhlung 15 in einem Abstands­bereich zur ebenen Unterseite 9′ des Deckels 9 ansetzt. Der diesbezügliche Boden der topfförmigen Vertiefung trägt das Bezugszeichen 22′.Above the throat 18, 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 '.

Die Zapfen-Aufnahmehöhlung 15 ist ausgefüttert. Es handelt sich um eine topfförmige Metallbüchse 23. Zur sicheren Ein­spritz-Verankerung bildet ihre Mantelfläche in der oberen Hälfte der Metallbüchse 23 eine Ringnut 24 aus. Die zur Steck-Rastverbindung beitragende Nut 13 liegt dagegen in dem demgegenüber wandungsdickeren Bereich der Metallbüchse 23. Ihr Stirnrand schließt ebenengleich mit dem Boden 22′ der Vertiefung 22 ab. Der Boden bzw. besser gesagt die Decke 25 der topfförmigen Metallbüchse 23 weist eine gegenüber der Wandung der Büchse größere Dicke auf. In Anpassung an die Fase 11′ des Zapfens 11 läuft der Boden in eine zentral orientierte Kegelmulde aus, und zwar unter Berücksichtigung des Fasenwinkels.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 contributing to the plug-lock connection groove 13, however, lies in the thicker wall area of the metal sleeve 23. Its end edge is flush with the bottom 22 'of the recess 22. 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.

Die Wählscheibe 8 weist an ihrer Oberseite in die Umfangsflä­che 8˝ der Wählscheibe 8 auslaufende Kehlen 26 auf (vergleiche Figuren 2 und 4). Über diese Kehlen läßt sich das Abstemmen des Deckels relativ leicht bewerkstelligen, indem man beispielsweise mit einer Fingerkuppe in den Be­reich der Kehle 26 fährt oder ein klingenartiges Werkzeug einsetzt und verkantet. Dagegen sind zufällige Berührungen mangels entsprechender Angriffsfläche nicht in eine Öffnungs­bewegung umsetzbar. Andererseits erweisen sich die sichel- oder linsenförmigen Kehlen auch als Drehhilfe. Beispielswei­se fettverschmierte Finger können nicht abrutschen. Es liegt vielmehr eine kronenartige Randrauhung für das Drehen der Wählscheibe vor, wenn nicht die oben erläuterte wählscheiben­artige Handhabung bevorzugt wird.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. On the other hand, 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.

Die Handhabung ist, kurz zusammengefaßt, wie folgt: Zum Entnehmen eines Schraubeinsatzes wird der Deckel 9 unter Überwindung der ihn fesselnden Rastkräfte vom Zapfen 11 abgezogen. Dadurch liegt die Wählscheibe 8 frei. Ihr Entnah­meloch 10 wird in die gewünschte, vorher zufolge der Durch­sichtigkeit des Magazins ausgewählte Position gefahren. Nach deckungsgleicher Ausrichtung von Loch und Fach braucht das Werkzeug nur im Sinne eines Ausschüttens gekippt zu werden. Die restlichen Schraubeinsätze 4 sind gegen Herausrutschen gesperrt. Nach Aufsetzen des Deckels liegt wieder die ergono­misch günstige Grundform des Heftkörpers vor, da der Deckel 9 eine domartig gewölbte Oberseite 9˝ aufweist, so daß der entsprechend kalottenförmig gestaltete Endanschnitt gut in der Hand liegt und so auch als Druckplatte fungieren kann.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.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestellten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
