For easy recognition of tools or wrenches, the supports for identification are formed from a coloured plastic part (K) which consists of a collar (5) surrounding the shank, the clear cross- section (6, 12) of which collar corresponds to the cross-section of the shank (3, 10) at the location surrounded by the plastic part (K), the colour of the plastic part (K) preferably being different for each tool or wrench size, but the same for identical tool or wrench sizes. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Werkzeug, insbesondere Schraubenschlüssel, mit einem am Werkstück bzw. der Schraube angreifenden Kopfteil und einem zum Anfassen dienenden, in der Dicke gegenüber dem Kopfteil rückversetzten schwächeren Schaft, auf dessen Breitseiten je eine Auflage zur Kennzeichnung des Werkzeuges bzw. des Schraubenschlüssels angebracht ist, die zwecks Befestigung am Werkzeug bzw. Schraubenschlüssel miteinander verbunden sind.The invention relates to a tool, in particular a wrench, with a head part acting on the workpiece or the screw and a grasping serving serving to touch, weaker in the thickness compared to the head part, on the broad sides of each a support to identify the tool or Wrench is attached, which are connected to each other for attachment to the tool or wrench.

Zur Kenntlichmachung der Größe, z. B. der Schraubenschlüssel, ist es üblich, auf beiden Seiten am oder nahe dem Kopfteil die Größe in Millimeter anzugeben, was durch irgendeine bekannte Methode, z.B. durch Einstanzen, geschehen kann. Diese Zeichen, die naturgemäß entsprechend klein sein müssen, sind insbesondere bei Verschmutzung des Werkzeuges, schlecht oder nicht lesbar. Es ist deshalb vielfach schwierig, aus einer Vielzahl von gleichartigen Werkzeugen, z. B. Schraubenschlüsseln das bzw. den jeweils richtige(n) rasch herauszufinden. Dies ist insbesondere bei schlechten Lichtverhältnissen oder bei übereinanderliegenden Werkzeugen, wie Schraubenschlüsseln, Zangen und Schraubenziehern der Fall, wo die Bezeichnungen der darunterliegenden Werkzeuge teilweise verdeckt sein können.To indicate the size, e.g. E.g. the wrench, it is common to indicate the size in millimeters on either side of or near the head part, which can be done by any known method, e.g. by punching. These characters, which naturally have to be correspondingly small, are bad or illegible, especially when the tool is dirty. It is therefore often difficult to use a variety of similar tools, e.g. B. wrenches to find out the correct one (s) quickly. This is particularly the case with poor lighting conditions or with tools lying on top of one another, such as wrenches, pliers and screwdrivers, where the names of the tools underneath can be partially hidden.

Aus der EP-A1 0 246 144 ist weiters ein Werkzeug, insbesondere Schraubenschlüssel bekannt, der auf einem flachen Griff mit einem abstehenden und umlaufenden Rand zwei einander ähnliche Identifizierungsplaketten aufweist, die beidseits des Werkzeugs angeordnet, vom umlaufenden Rand seitlich geführt und miteinander verbunden sind. Die Verbindung erfolgt hiebei über zwei Rundbohrungen im Schaft, z.B. durch Schweißen. Da die Identifizierungszeichen auf den somit versenkt am Schraubenschlüssel angebrachten Plaketten vorgesehen sind, sind auch hier naturgemäß die einleitend für die herkömmliche Schraubenschlüsselmarkierung z.B. durch Einstanzen, angegebenen Nachteile größtenteils vorhanden.From EP-A1 0 246 144 a tool, in particular a wrench, is also known which has two identifying badges on a flat handle with a protruding and circumferential edge, which are arranged on both sides of the tool, are guided laterally by the circumferential edge and are connected to one another. The connection is made via two round holes in the shaft, for example by welding. Since the identification marks are provided on the badges attached to the wrench, they are of course also the introductory part of the conventional wrench marking For example, by stamping, the disadvantages indicated largely exist.

Aufgabe der Erfindung ist es, die Nachteile der bekannten Werkzeugausführungen zu vermeiden und insbesondere ein rasches Auffinden eines Werkzeuges, z.B. eines Schraubenschlüssels gewünschter Größe besonders in größeren Werkstätten, zu erleichtern und dadurch den Arbeitsablauf zu verbessern und zu beschleunigen.The object of the invention is to avoid the disadvantages of the known tool designs and in particular to find a tool quickly, e.g. a wrench of the desired size, especially in larger workshops, and thereby improve and accelerate the workflow.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß die Auflagen zur Kennzeichnung von einem färbigen Kunststoffteil gebildet sind, der aus einer den Schaft umfassenden Manschette besteht, deren lichter Querschnitt dem Queischnitt des Schaftes an der vom Kunststoffteil umfaßten Stelle entspricht, wobei vorzugsweise die Farbe des Kunststoffteiles für jede Werkzeug- bzw. Schraubenschlüsselgröße verschieden, für gleiche Werkzeug- bzw. Schraubenschlüsselgrößen aber dieselbe ist. Dadurch ist das Auffinden eines Werkzeuges z.B. Schraubenschlüssels bestimmter Größe ohne weiteres möglich. Der Hauptvorteil der Werkzeuge, insbesondere Schraubenschlüssel mit Kunststoff-Kennzeichnung in der erfindungsgemäßen Form und derem Farbgebung liegt in der leichten Erkennbarkeit. Die farbige Kunststoff-Manschette stellt, im Gegensatz zu den bekannten Ausführungen, eine Rundum-Kennzeichnung des Werkzeuges dar, sodaß die genaue Größe des Werkzeuges, z.B. der Maulweiten des Schraubenschlüssels in jeder Lage des Schlüssels und bei jedem beliebigen Betrachtungswinkel leicht und eindeutig erkennbar sind. Es ergibt sich ferner ein sehr guter Sitz der Kennzeichnung auf dem Schaft des Werkzeuges sowie eine sehr gute Handhabung desselben. Durch die bunte Kunststoffkennzeichnung erhalten die Werkzeuge ein augenscheinlich neues Erscheinungsbild und erleichtern dadurch auch den Verkauf. Die Kunststoffmanschetten können problemlos farbbeständig, kratz- und schlagfest, benzin- und ölbeständig hergestellt werden, wobei die Formgebung in weiten Grenzen variiert werden kann.According to the invention, this object is achieved in that the supports for identification are formed by a colored plastic part, which consists of a sleeve surrounding the shaft, the clear cross-section of which corresponds to the cross-section of the shaft at the location encompassed by the plastic part, preferably the color of the Plastic part is different for each tool or wrench size, but is the same for the same tool or wrench sizes. This makes finding a tool e.g. Wrench of a certain size is easily possible. The main advantage of the tools, in particular wrenches with plastic identification in the shape according to the invention and their coloring, lies in the easy recognition. In contrast to the known designs, the colored plastic sleeve represents an all-round identification of the tool, so that the exact size of the tool, e.g. the width of the wrench in any position of the wrench and at any viewing angle are easily and clearly recognizable. There is also a very good fit of the marking on the shank of the tool and very good handling of the same. The colorful plastic marking gives the tools an apparently new appearance, which also makes sales easier. The plastic sleeves can easily be made color-resistant, scratch and impact resistant, petrol and oil resistant, whereby the shape can be varied within wide limits.

Es ist auch eine von den zu markierenden Werkzeugen zeitlich und örtlich unabhängige Herstellung des Kunststoffteiles von den Werkzeugen erreicht, wodurch die Produktionskosten niedrig gehalten werden können.It is also possible to produce the plastic part of the tools independently of the tools to be marked in terms of time and location, as a result of which the production costs can be kept low.

Für die Werkzeuge nach der Erfindung kann es von besonderem Vorteil sein, wenn der die Manschette bildende Kunststoffteil eine reflektierende und/oder fluoreszierende Farbe besitzt. Dadurch können die Werkzeuge auch bei schlechten Lichtverhältnissen, z.B. mittels einer Taschenlampe, leicht aufgefunden bzw. erkannt werden.For the tools according to the invention it can be particularly advantageous if the plastic part forming the sleeve has a reflective and / or fluorescent color. As a result, the tools can also be used in poor lighting conditions, e.g. can be easily found or recognized using a flashlight.

In weiterer Ausgestaltung der Erfindung kann der die Manschette bildende Kunststoffteil auf einer Breitseite, vorzugsweise in deren Mitte, einen der Länge nach verlaufenden Schlitz aufweisen und an der gegenüberliegenden zweiten Breitseite einen zum Eingriff in eine Durchbrechung des Schaftes dienenden Ansatz besitzen, und der Kunststoffteil zusätzlich durch Kleben oder Schweißen am Schaft befestigt sein. Unter gewissen Produktionsvoraussetzungen kann es von Vorteil sein, daß der Kunststoffteil an den Schaft angegossen wird.In a further embodiment of the invention, the plastic part forming the sleeve can have a slot running lengthwise on one broad side, preferably in the middle thereof, and have an attachment on the opposite second broad side for engaging in an opening in the shaft, and the plastic part additionally Glue or weld to the shaft. Under certain production conditions, it can be advantageous for the plastic part to be cast onto the shaft.

Von besonderem Vorteil ist es, wenn die Höhe des Kunststoffteiles höchstens gleich der Höhe des zugehörigen Kopfteiles des Werkzeuges ist. Dadurch wird eine Behinderung beim Einsatz des Schraubenschlüssels vermieden, die darin bestehen könnte, daß der Kopfteil des Werkzeuges nur so weit an eine parallel zum eingesetzten Schraubenschlüssel verlaufende Fläche herangebracht werden kann, als dies die Manschette zuläßt.It is particularly advantageous if the height of the plastic part is at most equal to the height of the associated head part of the tool. This avoids a hindrance when using the wrench, which could consist in the fact that the head part of the tool can only be brought up to a surface running parallel to the wrench used as far as the sleeve allows.

Der in Fig. 1 bis 3 dargestellte Doppel-Schraubenschlüssel weist auf einer Seite des Schaftes 3 einen Gabelkopf 1 und auf der anderen Seite einen Ringkopf 2 auf. Der im querschnitt doppel-T-förmige Schaft 3 weist nahe dem Gabelkopf 1 in seiner biegeneutralen Zone eine als Bohrung ausgeführte Durchbrechung 4 auf, welche durch die aus Kunststoff, beispielsweise aus mechanisch und chemisch widerstandsfähigem, thermoplastischem Material, bestehende Manschette 5 überdeckt ist. Die Manschette 5 weist einen lichten Querschnitt 6 auf, welcher dem doppel-T-förmigen Querschnitt des Schaftes 3 entspricht. Auf der unteren Breitseite ist ein zylindrischer Ansatz 7 angeformt, welcher im montierten Zustand die Durchbrechung 4 durchsetzt. Um die Montage zu ermöglichen, bzw. zu erleichtern, weist die Manschette 5 an ihrer dem Ansatz 7 gegenüberliegenden Seite einen Längsschlitz 8 auf, der das Überstülpen der Manschette über den Schaft 3 ermöglicht. Bei der Montage wird der Ansatz 7 durch die Durchbrechung 4 hindurchgesteckt und sodann durch Verschweißen oder Kleben zusätzlich mit dem Schaft 3 fest verbunden. Hiebei wird der Schlitz 8 geschlossen und die beiden den Schlitz 8 begrenzenden Stirnflächen 9 stoßen dann aufeinander, wie Fig. 2 zeigt. Die Manschette 5 weist eine der Größe des Gabelschlüssels zugeordnete Farbe auf. Ist der Ringkopf 2 für Schrauben der gleichen Größe bestimmt, so kann in der Nähe dieses Ringkopfes ebenfalls ein Kunststoffteil K bzw. eine Manschette 5 in der gleichen Farbe angebracht werden. Ist der Ringkopf 2 für eine andere Schraubengröße bestimmt als der Gabelkopf 1, so wird in der Nähe des Ringkopfes ein Kunststoffteil mit einer anderen Farbe angebracht.The double wrench shown in FIGS. 1 to 3 has a fork head 1 on one side of the shaft 3 and a ring head 2 on the other side. The cross-sectionally double-T-shaped shaft 3 near the fork head 1 in its bending-neutral zone has an opening 4 designed as a bore, which is covered by the sleeve 5 made of plastic, for example of mechanically and chemically resistant, thermoplastic material. The cuff 5 has a clear cross section 6, which corresponds to the double T-shaped cross section of the shaft 3. A cylindrical extension 7 is formed on the lower broad side and passes through the opening 4 in the assembled state. In order to enable or facilitate assembly, the sleeve 5 has a longitudinal slot 8 on its side opposite the shoulder 7, which enables the sleeve to be slipped over the shaft 3. During assembly, the projection 7 is pushed through the opening 4 and then additionally connected to the shaft 3 by welding or gluing. The slot 8 is closed and the two end faces 9 delimiting the slot 8 then meet, as shown in FIG. 2. The cuff 5 has a color assigned to the size of the fork wrench. If the ring head 2 is intended for screws of the same size, a plastic part K or a sleeve 5 in the same color can also be attached near this ring head. If the ring head 2 is intended for a different screw size than the fork head 1, a plastic part with a different color is attached in the vicinity of the ring head.

Die Fig. 4 bis 6 zeigen einen Schraubenschlüssel mit einem Ringkopf 2 und einem Schaft 10 mit im wesentlichen rechteckigem Querschnitt, welcher eine Durchbrechung in Form einer Bohrung 4 aufweist. Die darauf zu montierende Manschette 11 unterscheidet sich von der Manschette 5 lediglich durch den lichten Querschnitt 12, der dem Rechtecksquerschnitt des Schaftes 10 entspricht. Die übrigen gleichen Teile sind mit denselben Bezugszeichen wie in Fig. 2 und 3 versehen.4 to 6 show a wrench with a ring head 2 and a shaft 10 with an essentially rectangular cross section, which has an opening in the form of a bore 4. The cuff 11 to be mounted thereon differs from the cuff 5 only in the clear cross section 12, which corresponds to the rectangular cross section of the shaft 10. The remaining same parts are provided with the same reference numerals as in FIGS. 2 and 3.

Der mit der Manschette 5 umschlossene Teil des Schaftes 3 (Fig. 1-3) hat dieselbe Höhe h wie der Gabelkopf 1; es kann jedoch von Vorteil sein, wenn die Höhe des von der Manschette 5 umschlossenen Teiles des Schaftes 3 etwas niedriger ist als der Gabelkopf 1. Dasselbe gilt für den Ringkopf 2 am Schaft 10 (Fig. 4-6), wobei der mit der Kunststoffmanschette 11 umgebene Schaftteil die gleiche Höhe h′ aufweist wie der Ringkopf 2.The part of the shaft 3 (FIGS. 1-3) enclosed by the sleeve 5 has the same height h as the fork head 1; however, it can be beneficial if the height of the cuff 5 enclosed part of the shaft 3 is slightly lower than the fork head 1. The same applies to the ring head 2 on the shaft 10 (Fig. 4-6), the shaft part surrounded by the plastic sleeve 11 having the same height h 'as the ring head 2.
