Description

Werkzeug  Tool
Die Erfindung betrifft ein Werkzeug, insbesondere Schraubwerkzeug, mit einem Handgriff, einem mit dem Handgriff verbundenen, einem Öffnen oder Schließen einer Schraubverbindung dienenden Arbeitsteil und einer einen Arbeitswert, beispielsweise ein Anzugsmoment der Schraubverbindung anzeigenden Anzeigevorrichtung, wobei die Anzeigevorrichtung zumindest zwei Darstellungen des Arbeitswertes, insbesondere des Anzugsmomentes aufweist. The invention relates to a tool, in particular screwing, with a handle, a connected to the handle, opening or closing a screw working part and a labor value, for example, a tightening torque of the screw indicating display device, wherein the display device at least two representations of the labor value, in particular having the tightening torque.
Derartige Werkzeuge sind aus dem Stand der Technik bekannt und hierbei handelt es sich insbesondere um sogenannte Drehmoment-Schraubwerkzeuge, die einen Handgriff und einen Arbeitsteil aufweisen, welcher Arbeitsteil in der Regel aus einem drehbar in einem Kopf gelagerten Vierkant besteht, der in Abhängigkeit des Arbeitsvorgangs, nämlich des Öffnens oder Schließens einer Schraubverbindung sperrbar ist. Darüber hinaus weisen derartige Werkzeuge eine Einrichtung auf, die das Anzugsmoment des Werkzeugs in Abhängigkeit des zulässigen Anzugsmomentes der Schraubverbindung beschränken. In der Regel erhält der Benutzer dazu ein Signal (hörbar, sichtbar, fühlbar) von dem Werkzeug und oder der Kraftfluss wird ganz oder zweiteilig unterbrochen. Mit dieser Ausgestaltung kann das Werkzeug auf das zulässige Anzugsmoment der Schraubverbindung eingestellt werden, so dass ein zu großes Anzugsmoment vermieden wird. Beispielsweise sind derartige Vorgehensweisen bei der Montage von Leichtmetallrädern an Kraftfahrzeugen bekannt. Such tools are known from the prior art and these are in particular so-called torque screwdriving tools, which have a handle and a working part, which working part usually consists of a rotatably mounted in a head square, which depends on the operation, namely the opening or closing of a screw can be blocked. In addition, such tools have a device that limits the tightening torque of the tool as a function of the permissible tightening torque of the screw. As a rule, the user receives a signal (audible, visible, tactile) from the tool and / or the power flow is interrupted in whole or in two parts. With this configuration, the tool can be adjusted to the allowable torque of the screw, so that too large a tightening torque is avoided. For example, such procedures are known in the assembly of light-alloy wheels on motor vehicles.
Darüber hinaus weisen derartige Werkzeuge Anzeigevorrichtungen auf, die entsprechende Anzugsmomente bei der Handhabung des Werkzeugs anzeigen. Da für die Anzeige von Anzugsmomenten unterschiedliche Dimensionen verwendet werden, wie beispielsweise Newtonmeter (Nm) oder Ibf ft. ist es üblich, mehrere, zumindest zwei Arbeitswerte in der Anzeigevorrichtung anzuzeigen. In addition, such tools have display devices that indicate appropriate tightening torques when handling the tool. Since different dimensions are used for the display of tightening torques, such as Newton meters (Nm) or Ibf ft., It is common to display several, at least two working values in the display device.
Diese Anzeige führt aber mitunter zu Problemen, da nicht auszuschließen ist, dass das vorgesehene Anzugsmoment in der einen Dimension angegeben ist, die Handhabung des Werkzeugs aber in der anderen Dimension erfolgt, so dass ein zu großes oder ein zu geringes Anzugsmoment auf die Schraubverbindung übertragen wird. However, this display sometimes leads to problems, since it can not be ruled out that the intended tightening torque is specified in the one dimension, but the handling of the tool takes place in the other dimension, so that too great or too low a tightening torque is transmitted to the screw connection ,
Ein weiteres Problem derartiger Werkzeuge liegt darin, dass die Anzugsmomente justierbar sind und dass die Justierung derartiger Anzugsmomente nicht dauerhaft fehlerfrei arbeitet, so dass derartige Werkzeuge von Zeit zu Zeit kalibriert werden müssen. Auch hierbei könnte es durch eine Verwechslung der Einheiten zu Fehlern kommen. Another problem of such tools is that the torques are adjustable and that the adjustment of such torques does not work permanently error-free, so that such tools must be calibrated from time to time. Again, it could be due to a confusion of units to errors.
Ausgehend von dem voranstehend dargestellten Stand der Technik liegt der Erfindung die A u f g a b e zugrunde, ein gattungsgemäßes Werkzeug derart auszubilden, dass die voranstehend beschriebene fehlerhafte Handhabung mit ausreichender Sicherheit ausgeschlossen werden kann. Starting from the above-described prior art, the invention is based on the invention to form a generic tool such that the incorrect handling described above can be excluded with sufficient certainty.
Eine L ö s u n g dieser Aufgabenstellung sieht vor, dass eine Abdeckvorrichtung vorgesehen ist, die zumindest einen Arbeitswert abdeckt und/oder derart ausgebildet ist, dass lediglich ein Arbeitswert in der Anzeigevorrichtung anzeigbar ist. A solution of this problem provides that a covering device is provided which covers at least one labor value and / or is designed such that only one labor value can be displayed in the display device.
Demzufolge weist ein Werkzeug, insbesondere ein Schraubwerkzeug mit einer Anzeigevorrichtung ergänzend eine Abdeckvorrichtung auf, die derart bewegbar ist, dass immer nur maximal ein Arbeitswert der möglichen Arbeitswerte erkennbar ist. Hierdurch kann der Arbeitswert, insbesondere die Dimension voreingestellt werden, die mit dem Arbeitswert beziehungsweise der Dimension des für eine bestimmte Schraubverbindung vorgesehenen Anzugsmomentes übereinstimmt. Hierdurch lassen sich Fehlbedienungen aufgrund unterschiedlicher Dimensionen weitestgehend ausschließen. Die Anzeigevorrichtung ist vorzugsweise im Bereich des Handgriffs angeordnet, so dass die Anzeigevorrichtung für die handhabende Person sehr gut erkennbar ist. Vorzugsweise ist die Abdeckvorrichtung als Schieber ausgebildet, der zwischen zumindest zwei Einstellungen relativ zur Anzeigevorrichtung verschiebbar ist. Dem Grunde nach kann die Abdeckvorrichtung aber auch mehr als zwei Positionen relativ zur Anzeigevorrichtung einnehmen. Von Bedeutung ist hierbei lediglich, dass die Abdeckvorrichtung immer nur einen Arbeitswert in der Anzeigevorrichtung erkennen lässt, so dass Fehlhandhabungen aufgrund unterschiedlicher Arbeitswerte ausgeschlossen werden können. Accordingly, a tool, in particular a screwdriving tool with a display device additionally has a covering device which is movable in such a way that only a maximum of one working value of the possible working values is recognizable. In this way, the labor value, in particular the dimension can be preset, which coincides with the labor value or the dimension of the intended for a particular screw tightening torque. As a result, incorrect operation due to different dimensions can be largely excluded. The display device is preferably arranged in the region of the handle, so that the display device for the person handling is very easily recognizable. Preferably, the cover device is designed as a slide which is displaceable relative to the display device between at least two settings. Basically, however, the cover device can also occupy more than two positions relative to the display device. It is only important here that the cover device always reveals only one work value in the display device, so that incorrect handling due to different labor values can be ruled out.
Es besteht aber auch die Möglichkeit, dass der Schieber nicht verschiebbar sondern auf den Handgriff oder einen Skalenrahmen aufsteckbar ist, wobei auch in diesem Fall der Schieber derart ausgebildet ist, dass er nur einen Teilbereich der Anzeigevorrichtung erkennbar lässt, nämlich einen solchen Teilbereich, der entsprechend nur die Anzeige eines Arbeitswertes ermöglicht. But there is also the possibility that the slider is not displaceable but attachable to the handle or a scale frame, in which case the slider is designed such that it only recognizes a portion of the display device, namely such a sub-area corresponding to only the display of a labor value allows.
Es ist nach einer weiteren Ausgestaltung der Erfindung vorgesehen, dass die Abdeckvorrichtung an eine Außenkontur des Handgriffs angepasst ausgebildet und relativ zum Handgriff in Umfangsrichtung und / oder Längsrichtung des Handgriffs verschiebbar am Handgriff angeordnet ist. Vorzugsweise weist die Abdeckvorrichtung einen Umschalter oder Fingeransatz auf, der beispielsweise mittels des Daumens betätigbar ist, um die Abdeckvorrichtung vor der Handhabung des Werkzeugs auf die entsprechende Position einzustellen. It is provided according to a further embodiment of the invention that the covering device adapted to an outer contour of the handle adapted and is arranged relative to the handle in the circumferential direction and / or longitudinal direction of the handle displaceable on the handle. Preferably, the covering device has a switch or finger attachment which can be actuated, for example, by means of the thumb in order to adjust the covering device to the corresponding position before handling the tool.
Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass die Anzeigevorrichtung im Bereich einer Öffnung im Bereich des Handgriffs und/oder des Arbeitsteils angeordnet und relativ zu dieser Öffnung derart bewegbar, vorzugsweise verdrehbar ist, dass nur ein bestimmungsgemäßer Arbeitswert in der Öffnung erkennbar ist. Bei dieser Ausgestaltung wird die Anzeigevorrichtung nicht durch einen verschiebbaren und/oder aufsteckbaren Schieber teilweise abgedeckt, sondern ein Träger mit den Arbeitswerten wird relativ zur Anzeigevorrichtung, beispielsweise in Form einer Öffnung in dem Handgriff verschoben, so dass auch in diesem Fall lediglich ein eingestellter Arbeitswert durch die Anzeigevorrichtung erkennbar ist. Die Abdeckvorrichtung kann mit einer Zugangsberechtigungsvorrichtung ausgebildet sein, so dass eine Verstellung der Abdeckvorrichtung nur mit einer Zugangsberechtigung ermöglicht ist. Auf diese Weise ist sichergestellt, dass die Abdeckvorrichtung nicht während der Handhabung unbeabsichtigt verstellt wird, so dass nach der Verstellung Fehlhandhabungen aufgrund unterschiedlicher Dimensionen verursacht werden. According to a further feature of the invention it is provided that the display device is arranged in the region of an opening in the region of the handle and / or the working part and relative to this opening so movable, preferably rotatable that only a normal working value in the opening can be seen. In this embodiment, the display device is not partially covered by a displaceable and / or attachable slide, but a carrier with the working values is relatively shifted to the display device, for example in the form of an opening in the handle, so that in this case only a set work value the display device is recognizable. The cover device may be formed with an access authorization device, so that an adjustment of the cover device is only possible with an access authorization. In this way, it is ensured that the cover device is not inadvertently adjusted during handling, so that caused by the adjustment incorrect handling due to different dimensions.
Wie bereits ausgeführt ist es nach einem weiteren Merkmal der Erfindung vorgesehen, dass ein solches Werkzeug als Drehmoment-Schraubwerkzeug ausgebildet ist, welches beispielsweise eine Aufnahme in Form eines Vierkants für Aufsteckwerkzeuge aufweist. Es besteht aber auch die Möglichkeit, dass ein derartiges Werkzeug als Schraubendreher ausgebildet ist beziehungsweise das entsprechende Werkzeugeinsätze, sogenannte Bits-in entsprechenden Aufnahmen angeordnet werden können. As already stated, it is provided according to a further feature of the invention that such a tool is designed as a torque-screwing tool, which has, for example, a receptacle in the form of a square for Aufsteckwerkzeuge. But there is also the possibility that such a tool is designed as a screwdriver or the corresponding tool inserts, so-called bits can be arranged in corresponding receptacles.
Ergänzend ist bei einem erfindungsgemäßen Werkzeug vorgesehen, dass die Abdeckvorrichtung mittels eines Umschalters bewegbar ist, wobei der Umschalter vorzugsweise in einer Führung geführt ist. Durch die Führung ist die Bewegbarkeit der Abdeckvorrichtung definiert. Der Umschalter ist zwischen zwei Endstellungen bewegbar, bei denen es sich hinsichtlich der Abdeckvorrichtung um solche Stellungen handelt, die lediglich einen Bereich der Anzeigevorrichtung erkennbar lassen. Die Führung des Umschalters ermöglicht eine einfache Handhabung. In addition, it is provided in a tool according to the invention that the cover device is movable by means of a changeover switch, wherein the changeover switch is preferably guided in a guide. By the leadership of the mobility of the cover device is defined. The switch is movable between two end positions in which it is in terms of the cover device to such positions, which can only recognize a portion of the display device. The leadership of the switch allows easy handling.
Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass der Umschalter in seinen Endstellungen in der Führung mit dem Handgriff verrastbar ist. Diese Ausgestaltung verhindert ein unbeabsichtigtes Verstellen der Abdeckvorrichtung während der Handhabung des Werkzeuges, wobei die nicht unerhebliche Gefahr bestehen würde, dass eine derartige unbeabsichtigte Verstellung bei der weiteren Arbeit mit dem Werkzeug unbemerkt bleibt, so dass anschließend fehlerhafte Arbeiten mit dem Werkzeug ausgeführt werden. According to a further feature of the invention it is provided that the switch can be latched in its end positions in the guide with the handle. This embodiment prevents inadvertent adjustment of the covering during handling of the tool, wherein the considerable risk would exist that such unintentional adjustment goes unnoticed in the further work with the tool, so that subsequently erroneous work is performed with the tool.
Vorzugsweise ist der Umschalter mit endseitigen Ausnehmungen ausgebildet, in die im Handgriff angeordnete federbelastete Rastelemente, insbesondere Kugeln oder ein halbkugelförmiges Ende aufweisende Stifte eingreifen. Alternativ kann vorgesehen sein, dass im Umschalter federbelastete Rastelemente, insbesondere Kugeln oder ein halbkugelförmiges Ende aufweisende Stifte angeordnet sind, die in Ausnehmung des Handgriffs eingreifen. Durch die Rastelemente wird der Umschalter und damit die daran befestigte Abdeckvorrichtung in den gegenüberliegend angeordneten Endstellungen fixiert. Die Fixierung ist nur durch Aufbringen einer erhöhten Kraft aufhebbar, die in der Regel nicht dadurch aufgebracht wird, dass mit dem Werkzeug gearbeitet wird. Vielmehr wird diese Kraft ganz bewusst bei der Betätigung des Umschalters zur Verstellung der Abdeckvorrichtung aufgebracht, so dass hier ein gezieltes Handeln verbunden mit der Einstellung des Werkzeuges erfolgt. Die Rastelemente können entweder im Umschalter oder im Handgriff angeordnet sei beispielsweise jeweils aus einer federbelasteten Kugel bestehen, die in der ordnungsgemäßen Endstellung in eine entsprechende Ausnehmung durch die Feder eingedrückt wird. Alternativ kann aber auch ein Stift vorgesehen sein, der ein halbkugelförmiges Ende aufweist, welches der Ausnehmung zugewandt ausgerichtet ist. Durch die Ausgestaltung der Rastelemente als Kugeln oder als ein halbkugelförmiges Ende aufweisende Stifte wird die Handhabung vereinfacht und dennoch das Einnehmen der Raststellung deutlich wahrnehmbar angezeigt. Es sind selbstverständlich auch andere Rastelemente, wie federbelastete Schieber oder vorgespannte Kunststoffelemente mit Rastvorsprüngen möglich, die in korrespondierende Ausnehmungen einrasten. Darüber hinaus ist es auch nicht zwingend, dass die Rastelemente endseitig angeordnet sind. Es besteht auch die Möglichkeit ein Rastelement im Mittelbereich des Umschalters anzuordnen, wobei jedoch dafür Sorge getragen werden muss, dass die beiden Raststellungen deutlich wahrnehmbar sind und darüber hinaus eine deutliche Festlegung des Umschalters in der Führung ermöglichen. Preferably, the switch is formed with end-side recesses into which arranged in the handle spring-loaded locking elements, in particular balls or a hemispherical end having pins engage. Alternatively it can be provided that in the switch spring-loaded locking elements, in particular Arranged spheres or a hemispherical end having pins which engage in recess of the handle. By the locking elements of the switch and thus the cover device attached thereto is fixed in the opposite end positions. The fixation can only be canceled by applying an increased force, which is usually not applied by working with the tool. Rather, this force is deliberately applied to the operation of the switch for adjusting the covering, so that there is a targeted action associated with the setting of the tool. The locking elements can be arranged either in the switch or in the handle, for example, each consist of a spring-loaded ball, which is pressed in the proper end position in a corresponding recess by the spring. Alternatively, however, a pin may be provided which has a hemispherical end, which is aligned facing the recess. Due to the design of the locking elements as balls or as a hemispherical end having pins handling is simplified and yet the adoption of the detent position clearly visible. There are of course other locking elements, such as spring-loaded slide or prestressed plastic elements with locking projections possible, which engage in corresponding recesses. Moreover, it is also not mandatory that the locking elements are arranged end. It is also possible to arrange a locking element in the central region of the switch, but care must be taken that the two locking positions are clearly perceptible and also allow a clear determination of the switch in the guide.

Fig. 1 zeigt ein Schraubwerkzeug 1 in Form eines Drehmoment-Schraubwerkzeuges mit einem Handgriff 2, der im Wesentlichen einen kreisförmigen Querschnitt aufweist. Der Handgriff 2 besteht vorzugsweise aus einem oder mehreren Kunststoffen. Fig. 1 shows a screwing tool 1 in the form of a torque-screwing tool with a handle 2, which has a substantially circular cross-section. The handle 2 is preferably made of one or more plastics.
An einem mit dem Handgriff 2 verbundenen Ende 4 weist das Schraubwerkzeug 1 einen Arbeitsteil 5 üblicher Ausgestaltung auf. Der Arbeitsteil 5 besteht aus einem im Wesentlichen ringförmigen Gehäuse 6, in welches ein drehbares Element 7 eingesetzt ist, dessen Drehbarkeit relativ zum Gehäuse 6 alternativ in beide Drehrichtungen festlegbar ist und welches Element 7 einen im Querschnitt quadratischen Antrieb 8 aufweist, der mit nicht näher dargestellten Werkzeugnüssen verbindbar ist, die unterschiedliche Schlüsselweiten aufweisen und die der Verbindung mit der nicht näher dargestellten Schraubverbindung dienen. Des Weiteren sind Arbeitsteile in Form eines Zapfens einer Rechteckaufnahme oder weiteren nicht näher beschriebener Aufnahmen bekannt um Werkzeuge mit unterschiedlicher Form und/oder Schlüsselweite anbringen zu können. At an end 4 connected to the handle 2, the screwing tool 1 has a working part 5 of conventional design. The working part 5 consists of a substantially annular housing 6, in which a rotatable element 7 is inserted, whose rotatability relative to the housing 6 is alternatively fixed in both directions of rotation and which element 7 has a square in cross section drive 8, which is not shown in detail Tool nuts can be connected, which have different key widths and which serve the connection with the screw not shown. Furthermore, working parts in the form of a pin of a rectangular recording or other unspecified recordings are known to attach tools with different shape and / or width across flats.
Der Antrieb 8 ist hinsichtlich seines übertragbaren Drehmoments beispielsweise durch Verdrehen zweier Abschnitte des Handgriffs 2 relativ zueinander einstellbar. The drive 8 is adjustable relative to one another with regard to its transmittable torque, for example by turning two sections of the handle 2.
Die Technik eines derartigen Drehmoment-Schraubwerkzeugs ist hinlänglich bekannt und es wird diesbezüglich auf die DE 203 15 000 U1 verwiesen, die eine Ausführungsform eines derartigen Drehmoment-Schraubwerkzeugs offenbart. The technique of such torque wrenching tool is well known and reference is made in this regard to DE 203 15 000 U1, which discloses an embodiment of such a torque wrenching tool.
Das Schraubwerkzeug 1 gemäß Fig. 1 weist darüber hinaus eine Anzeigevorrichtung 10 auf, die der Anzeige verschiedener Arbeitswerte dient. In der Regel werden in derartigen Anzeigevorrichtungen 10 die vom Schraubwerkzeug 1 auf die Schraubverbindung zu übertragenen Anzugsmomente angezeigt. Eine detaillierte Darstellung der Anzeigevorrichtung 10 ergibt sich aus den Fig. 2 bis 4, die nachfolgend beschrieben werden. The screwing tool 1 according to FIG. 1 furthermore has a display device 10, which serves to display various working values. As a rule, in such display devices 10, the tightening torques to be transmitted from the screwing tool 1 to the screw connection are displayed. A detailed representation of the display device 10 results from FIGS. 2 to 4, which are described below.
Fig. 2 ist zu entnehmen, dass die Anzeigevorrichtung 10 eine erste Skala aufweist, die aus einer Werteangabe 12 und einem daneben angeordneten Einheitenfeld 13 besteht. Die Werteangabe 12 weist eine feststehende Referenzlinie 14 (Fig.en 3 und 4) sowie eine relativ zur Referenzlinie 14 bewegbare Skalierung 15 (Fig.en 3 und 4) auf. FIG. 2 shows that the display device 10 has a first scale, which consists of a value specification 12 and a unit field 13 arranged next to it. The value indication 12 has a fixed reference line 14 (FIGS. 3 and 4) and a scaling 15 (FIGS. 3 and 4) which can be moved relative to the reference line 14.
Neben der ersten Skala 1 1 kann eine zweite, als Nonius-Skala 16 ausgebildete Skala vorgesehen sein, die sich in Längsrichtung des Handgriffs 2 oberhalb der ersten Skala 11 befindet. Diese Nonius-Skala 16 und die Position der Referenzlinie zeigen dass eingestellte Anzugsmoment an. In addition to the first scale 11, a second scale designed as a vernier scale 16 may be provided, which is located in the longitudinal direction of the handle 2 above the first scale 11. This vernier scale 16 and the position of the reference line indicate the set tightening torque.
In Fig. 2 ist nur ein Teil der Anzeigevorrichtung 10 dargestellt, die unterteilt ist in den in Fig. 2 beziehungsweise Fig. 3 dargestellten Teil und den in Fig. 4 dargestellten Teil, der die Anzeige des Anzugsmoment in einer anderen Dimension nämlich Ibf. ft aufweist, während in den Fig. 2 und 3 zu erkennen ist, dass das Anzugsmoment in der Dimension Nm (Newtonmeter) dargestellt ist. Andere Dimensionen, wie Ibt.in, Kgm, Kgfm, Kpm oder dergleichen sind möglich. In Fig. 2, only a part of the display device 10 is shown, which is divided into the part shown in Fig. 2 and Fig. 3 and the part shown in Fig. 4, the display of the tightening torque in another dimension namely Ibf. ft, while it can be seen in FIGS. 2 and 3 that the tightening torque is shown in the dimension Nm (Newton meters). Other dimensions, such as Ibt.in, Kgm, Kgfm, Kpm or the like are possible.
Das Schraubwerkzeug 1 weist im Bereich der Anzeigevorrichtung 10 eine Abdeckvorrichtung 17 auf, die als Schieber ausgebildet ist und relativ zum Skalenrahmen 3 radial zwischen zwei Endstellungen verschiebbar ist. Zu diesem Zweck ist die Abdeckvorrichtung 17 mit einem Umschalter 18 ausgebildet, der in einer Führung 19 des Handgriffs 2 geführt ist, wobei die Führung 19 die beiden Endstellungen definiert. The screwing tool 1 has in the region of the display device 10 on a cover 17, which is designed as a slide and is displaceable relative to the scale frame 3 radially between two end positions. For this purpose, the cover 17 is formed with a switch 18 which is guided in a guide 19 of the handle 2, wherein the guide 19 defines the two end positions.
Der Umschalter 18 kann hierbei in besonders griffgünstiger Weise mittels des Daumens einer handhabenden Person bedient werden. The switch 18 can be operated in a particularly convenient way by means of the thumb of a person handling.
Über den Umschalter 18 wird die Abdeckvorrichtung 17 derart bewegt, dass in der Anzeigevorrichtung 10 immer nur ein Arbeitswert erkennbar ist, während der zweite Arbeitswert abgedeckt ist, wobei die Arbeitswerte eine Angabe des eingestellten Anzugsmomentes in einer Dimension Nm oder Ibf.ft sind. Die Abdeckung eines Arbeitsbetrages schließt Fehlablesungen aus. Hierbei ist zu berücksichtigen, dass bei der Arbeit mit derartigen Schraubwerkzeugen 1 der handhabenden Person für die betreffende Schraubverbindung ein bestimmtes Anzugsmoment vorgegeben ist. Um dieses Anzugsmoment nicht wesentlich zu überschreiten ist es für die handhabende Person erforderlich, das momentan eingestellte Anzugsmoment zu kennen. Da die Anzugsmomente in unterschiedlichen Dimensionen angegeben werden ist es nicht unüblich, dass fehlerhafte Bedienungen derartiger Schraubwerkzeuge 1 ausgeführt werden, bei denen beispielsweise ein vorgegebenes Anzugsmoment in Nm auf der Skala in Ibf.ft eingestellt wurde. Hierdurch kann es zu nicht korrekt angezogenen Schraubverbindungen kommen. About the changeover switch 18, the cover 17 is moved so that in the display device 10 only a labor value is recognizable, while the second labor value is covered, the labor values are an indication of the set torque in a dimension Nm or Ibf.ft. The cover of a Amount of work excludes incorrect readings. It should be noted that when working with such a screwing tools 1 of the person handling a specific torque is specified for the relevant screw. In order not to exceed this tightening torque significantly, it is necessary for the person handling to know the currently set tightening torque. Since the torques are given in different dimensions, it is not uncommon that erroneous operations of such screwing tools 1 are performed in which, for example, a predetermined torque in Nm was set on the scale in Ibf.ft. This can lead to incorrectly tightened screw.
Die Fig. 3 und 4 zeigen die Anzeigevorrichtung 10 in Fig. 3 in einer Darstellung des momentan eingestellten Anzugsmomentes in Nm und in Fig. 4 in Ibf.ft und es ist zu erkennen, dass der Umschalter 18 in Fig. 3 an einem ersten Ende der Führung 19 und in Fig. 4 am gegenüberliegenden Ende der Führung 19 angeordnet ist. Hierdurch ist erkennbar, dass die Abdeckvorrichtung 17 relativ zum Handgriff 2 verschiebbar ausgebildet ist, wobei sich die Abdeckvorrichtung 17 zwischen zwei Endstellungen um den Handgriff 2 herum verdrehen lässt. Die Nonius Skala kann sich in der Regel nur auf eine Einheit beziehen (z.B. Nm) und wird daher bei der Verwendung der alternativen Einheit abgedeckt. 3 and 4 show the display device 10 in Fig. 3 in a representation of the currently set torque in Nm and in Fig. 4 in Ibf.ft and it can be seen that the switch 18 in Fig. 3 at a first end the guide 19 and in Fig. 4 at the opposite end of the guide 19 is arranged. As a result, it can be seen that the covering device 17 is designed to be displaceable relative to the handle 2, wherein the covering device 17 can be rotated around the handle 2 between two end positions. The vernier scale can usually only refer to one unit (e.g., Nm) and is therefore covered when using the alternative unit.
Die voranstehend beschriebene Ausführungsform gemäß den Fig. 1 bis 4 stellt lediglich eine Ausführungsform dar. Es besteht auch die Möglichkeit, dass nicht die Abdeckvorrichtung 17 relativ zum Handgriff 2 bzw. Skalenrahmen 3 verdrehbar ist, sondern dass die Anzeigevorrichtung 10 relativ zu einer Öffnung im Handgriff 2 verstellbar ist, so dass über diese Öffnung, die wiederum die Anzeigevorrichtung 10 darstellt lediglich ein Wertebereich erkennbar ist. The embodiment described above according to FIGS. 1 to 4 represents only one embodiment. It is also possible that the cover device 17 is not rotatable relative to the handle 2 or scale frame 3, but that the display device 10 relative to an opening in the handle 2 is adjustable, so that this opening, which in turn represents the display device 10, only a range of values can be seen.
