Description

.Die vorliegende Erfindung betrifft ein Werkzeugheft, bestehend aus einem Heftkörper mit mittiger Längsbohrung zur Aufnahme eines Werkzeugschaftes sowie mit am vorderen Ende ausgebildetem Kragen und einer sich daran anschließenden konkav profilierten Zylinderzone und einem sich an die Zylinderzone anschließenden doppel-konischen Abschnitt.The present invention relates to a tool booklet, consisting of a booklet body with a central longitudinal bore for receiving a tool shaft and with a collar formed at the front end and an adjoining concavely profiled cylinder zone and a double-conical section adjoining the cylinder zone.

Ein derartiges Werkzeugheft ist z. B. bereits aus der DE-PS 1 298 060 bekannt. Bei diesem Werkzeugheft tragen die konischen Bereiche des doppel-konischen Abschnitts in winkelsymmetrischer Anordnung um die Längsachse liegend Einzelhohlkehlen, die in Längsrichtung des Heftes konkav verlaufen. Dieses bekannte Werkzeugheft ist insbesondere auf die Verwendung in Verbindung mit Schraubendrehern abgestellt und ergonomisch gestaltet. Soll das Werkzeugheft aber als universelles Werkzeugheft an vielen verschiedenen Werkzeugen, wie z. B. bei Knarren zum Antrieb bei Steckschlüsseleinsätzen oder bei Drehkurbeln für Steckschlüssel oder als Feilenheft oder auch als handliches Heft für Schraubendreher, Verwendung finden, so wird durch.die mittlere Ringzone zwischen den beiden konischen Bereichen des doppel-konischen Abschnitts ein optimaler Halt in der Hand der Bedienungsperson, der aber zur Kraftübertragung erforderlich ist, verhindert.Such a tool book is z. B. already known from DE-PS 1 298 060. In this tool booklet, the conical areas of the double-conical section have angularly symmetrical arrangements around the longitudinal axis of individual grooves which are concave in the longitudinal direction of the booklet. This well-known tool book is especially designed for use in connection with screwdrivers and is ergonomically designed. Should that Tool booklet as a universal tool booklet on many different tools, such as B. with ratchets for driving socket wrench inserts or with crank handles for socket wrenches or as a file handle or also as a handy handle for screwdrivers, the middle ring zone between the two conical areas of the double-conical section provides an optimal hold in the hand the operator, but which is required for power transmission, prevented.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, ein Werkzeugheft derart zu gestalten, daß es universell für die unterschiedlichsten Werkzeuge, z.B. Knarren, Drehkurbeln, Feilen, Schraubendreher, Verwendung finden kann, und zwar in einer derartigen Weise, daß unter Ermöglichung einer optimalen Kraftübertragung von der Bedienungshand auf das Werkzeugheft und einer ergonomisch der geschlossenen Hand angepaßten Form.The present invention has for its object to design a tool book so that it is universal for a wide variety of tools, e.g. Creaking, turning cranks, files, screwdrivers, can be used in such a way that, while allowing optimal power transmission from the operating hand to the tool booklet and an ergonomically adapted shape of the closed hand.

Erfindungsgemäß wird dies dadurch erreicht, daß mindestens der doppel-konische Abschnitt einen quadratischen Querschnitt über seine gesamte Länge besitzt. Durch den durchgehenden quadratischen Querschnitt wird der beispielsweise aus dem Stand der Technik bekannte Ringbereich vermieden und somit insbesondere bei der Verwendung des Heftes in Verbindung mit Knarren oder Drehkurbeln ein besonders sicherer Halt des Werkzeug- _heftes in der Bedienungshand gewährleistet. Durch die doppel-konische Form des hinteren Bereiches des Werkzeugheftes in Verbindung mit der konkav profilierten Zylinderzone besitzt das erfindungsgemäße Werkzeugheft aber auch eine sehr gute Eignung in Verbindung mit Schraubendrehern. Der wesentliche Vorteil des erfindungsgemäßen Werkzeugheftes ist also die universelle Form, welche sich nicht nur auf ein Werkzeug festlegt, sondern auf eine Vielzahl von Handwerkzeugen aller Art, aber trotzdem allen Handantriebsarten derart gerecht wird, daß sowohl beim Ziehen, Drehen oder Drücken ein hohes Drehmoment bzw. eine hohe Kraft übertragen werden kann, ohne daß in der geschlossenen Hand ein Schmerzgefühl erzeugt wird, so daß auch Druckstellen bei längerem Gebrauch vermieden werden.This is achieved according to the invention in that at least the double-conical section has a square cross section over its entire length. The continuous square cross section avoids the ring area known from the prior art, for example, and thus ensures a particularly secure hold of the tool booklet in the operating hand, especially when the booklet is used in conjunction with ratchets or rotary cranks. Due to the double-conical shape of the rear area of the tool handle in connection with the concave profiled cylinder zone, the tool handle according to the invention is also very suitable in connection with screws spin. The main advantage of the tool booklet according to the invention is thus the universal shape, which is not only determined by one tool, but also by a multitude of hand tools of all kinds, but nevertheless does justice to all types of manual drive in such a way that a high torque or torque is obtained when pulling, turning or pressing A high force can be transmitted without causing a feeling of pain in the closed hand, so that pressure points are avoided with prolonged use.

Anhand des in den beiliegenden Zeichnungen dargestellten Ausführungsbeispiels wird die Erfindung näher erläutert. Es zeigen:

  • Fig. 1 eine perspektivische Ansicht eines erfindungsgemäßen Werkzeugheftes,
  • Fig. 2 eine Ansicht von hinten auf das erfindungsgemäße Werkzeugheft, wenn es von einer Bedienungshand umschlossen ist,
  • Fig. 3 einen Schnitt entlang der Schnittlinie III-III in Fig. 1.
The invention is explained in more detail with reference to the exemplary embodiment illustrated in the accompanying drawings. Show it:
  • 1 is a perspective view of a tool booklet according to the invention,
  • 2 is a rear view of the tool booklet according to the invention when it is enclosed by an operating hand,
  • 3 shows a section along the section line III-III in FIG. 1.

Ein erfindungsgemäßes Werkzeugheft besteht aus einem Heftkörper 1, der an seinem vorderen Ende, das dem Schaft eines einzusetzenden Werkzeuges zugekehrt ist, einen zylindrischen Kragen 2 aufweist. Zur Aufnahme des Werkzeugschaftes besitzt der Heftkörper 1 eine mittige Längsbohrung 3. An den Kragen 2 schließt sich eine konkav profilierte Zylinderzone 4 an. Das dem Kragen 2 gegenüberliegende Ende 5 der Zylinderzone 4 besitzt vorzugsweise einen größeren Durchmesser als der Kragen 2. Vom Ende 5 aus ist eine abfallende, mit großem Durchmesser ausgerundete Zone 6 ausgebildet, die in einen ersten ansteigenden Konusbereich 7 eines doppel- konischen Abschnitts 8 übergeht, und zwar mit einem großen Rundungsdurchmesser. Den hinteren Endbereich des Heftkörpers 1 bildet ein abfallender zweiter Konusbereich 9 des doppel-konischen Abschnitts 8. Die Querschnittsfläche des Heftkörpers 1 ist von dem Ende 5 ab bis zur hinteren Endfläche 10 stets quadratisch, wobei die vier Längskanten 11 bzw. die Ecken der Querschnittsfläche abgerundet sind. Der Übergang 2 der beiden Konusbereiche 7, 9 besitzt die größte Querschnittsfläche, so daß der Heftkörper von vorne bis zum Übergang 2 im ganzen dicker wird. Vorteilhafterweise beträgt die Kantenlänge der quadratischen Querschnittsfläche am Übergang 12 etwa 25 % mehr als am Ende 5 der konkaven Zylinderzone 4, und die Kantenlänge der Querschnittsfläche am Ende 5 ist etwa 10 % größer als der Durchmesser des Kragens 2. Die Längen der einzelnen Bereiche bzw. Abschnitte sind derart bemessen, daß die Bereiche, die abfallende Zone 6 und der erste Konusbereich 7, zusammen insgesamt länger sind als jeweils die Zylinderzone 4 oder der Konusbereich 9. Hierbei ist der Konusbereich 9 kürzer als die Zylinderzone 4. Die abfallende Zone 6 und der erste Konusbereich 7 sind zusammen etwa 15 % länger als die Zylinderzone 4,und der Konusbereich 9 ist etwa 15 % kürzer als die Zylinderzone 4. Aufgrund dieser vorteilhaften Gestaltung des Heftkörpers ergibt sich eine . besonders günstige Lage des Heftes in der Bedienungshand, wobei die verschiedenen Längen, wie sie im Vorstehenden beschrieben sind, der einzelnen Bereiche, insbesondere die Verlängerung.der konkaven Zylinderzone gegenüber dem Endbereich 9, es erlauben, daß die Finger der Bedienungshand relativ gestreckt sind, wodurch sich eine besonders angenehme und entspannte Handhaltung ergibt.A tool booklet according to the invention consists of a booklet body 1 which has a cylindrical collar 2 at its front end which faces the shaft of a tool to be used. The tacking body 1 has a central longitudinal bore 3 for receiving the tool shank. A concave profiled cylinder zone 4 adjoins the collar 2. The end 5 of the cylinder zone 4 opposite the collar 2 preferably has a larger diameter than the collar 2. From the end 5 there is a sloping one with a large one Diameter rounded zone 6 formed, which merges into a first rising cone region 7 of a double-conical section 8, with a large rounding diameter. The rear end area of the tack body 1 is formed by a sloping second cone area 9 of the double-conical section 8. The cross-sectional area of the tack body 1 is always square from the end 5 to the rear end face 10, the four longitudinal edges 11 or the corners of the cross-sectional area being rounded off are. The transition 2 of the two cone regions 7, 9 has the largest cross-sectional area, so that the stitching body becomes thicker from the front to the transition 2 as a whole. The edge length of the square cross-sectional area at the transition 12 is approximately 25% more than at the end 5 of the concave cylinder zone 4, and the edge length of the cross-sectional area at the end 5 is approximately 10% larger than the diameter of the collar 2. The lengths of the individual areas or Sections are dimensioned such that the areas, the falling zone 6 and the first cone area 7, together are overall longer than the cylinder zone 4 or the cone area 9. The cone area 9 is shorter than the cylinder zone 4. The falling zone 6 and the first cone region 7 are together approximately 15% longer than cylinder zone 4, and cone region 9 is approximately 15% shorter than cylinder zone 4. This advantageous design of the stitching body results in a. Particularly favorable position of the booklet in the operating hand, the different lengths, as described above, of the individual areas, in particular the extension. of the concave cylinder zone relative to the end area 9, allow the Fingers of the operating hand are relatively stretched, which results in a particularly pleasant and relaxed hand position.

Aus Fig. 3 ist ersichtlich, daß durch den quadratischen Querschnitt des Heftkörpers 1 hinter der Zylinderzone 4 eine Kontur des Werkzeugheftes erreicht wird, die in optimaler Weise der Form einer geschlossenen Hand angepaßt ist, wodurch sich das erfindungsgemäße Werkzeugheft insbesondere auch als Werkzeugheft für Knarren und Drehkurbeln eignet. Durch die Abrundung der Ecken und ebenfalls die Abrundung der Übergangsbereiche mit großen Rundungsradius wird eine Verletzungsgefahr der inneren Handfläche weitgehend vermieden, wobei trotzdem' ein hinreichend großer Widerstand erhalten bleibt, der eine sichere Handhabung gewährleistet.From Fig. 3 it can be seen that a contour of the tool handle is achieved by the square cross section of the handle body 1 behind the cylinder zone 4, which is optimally adapted to the shape of a closed hand, whereby the tool handle according to the invention in particular as a tool handle for creaking and Crank handles. By rounding the corners and also rounding off the transition areas with a large radius of curvature, a risk of injury to the inner palm is largely avoided, although a sufficiently high resistance is maintained which ensures safe handling.
