Abstract

A handle for a file contains an elongated cross-sectionally polygonal body having a constriction (16) in the file-side end region of the handle and a second constriction (13) in the free end region. Beyond the constriction of the free end region, the end (11) of the file is constructed in the form of a partial sphere, the sphere preferably being larger than a hemisphere. <IMAGE>

Description

Die Erfindung betrifft ein Feilenheft nach dem ersten Teil des Anspruchs 1.The invention relates to a file handle according to the first part of claim 1.

Feilen haben üblicherweise ein aus Holz oder Kunststoff bestehendes Heft, das eine langgestreckte Form aufweist. Im feilenseitigen Endbereich ist eine sehr flache Einschnürung vorhanden, während sich im Bereich des gegenüberliegenden freien Endes das Heft allmählich verjüngt, so daß eine zwar abgerundete, aber doch relativ schmale Endfläche gebildet wird. Der Griff hat üblicherweise einen kreisrunden Querschnitt.Files usually have a handle made of wood or plastic that has an elongated shape. A very flat constriction is present in the file-side end area, while the booklet gradually tapers in the area of the opposite free end, so that a rounded, but relatively narrow end surface is formed. The handle usually has a circular cross section.

Bei sehr kleinen Feilen ist es auch schon bekannt, aus Kunststoff bestehende Hefte zu verwenden, die einen ovalen Griffquerschnitt aufweisen.In the case of very small files, it is also known to use plastic-made booklets with an oval grip cross-section.

Bei einem bekannten Feilenheft der eingangs genannten Art (US-A-20 56 054) ist das Ende derart abgerundet, daß im Längsschnitt eine ellipsenartige Form gegeben ist. Das Feilenheft enthält eine Stelle eines zweiten Durchmessermaximums, so daß vor dem abgerundeten Endbereich eine Einschnürung gegeben ist, in der ein Finger liegen kann. Der Querschnitt des Feilenhefts ist kreisrund.In a known file handle of the type mentioned (US-A-20 56 054), the end is rounded such that an elliptical shape is given in longitudinal section. The file booklet contains one point of a second maximum diameter, so that there is a constriction in front of the rounded end region in which a finger can lie. The cross section of the file handle is circular.

Weiterhin bekannt ist ein Feilenheft (US-A-23 77 745), bei dem in dem der Feile zugewandten Endbereich des Griffs Vertiefungen für den Zeigefinger angeordnet sind. Damit soll dem Benutzer die Möglichkeit gegeben werden, die Orientierung der Feile zu fühlen.Also known is a file booklet (US Pat. No. 2,377,745) in which depressions for the index finger are arranged in the end region of the handle facing the file. This is intended to give the user the opportunity to feel the orientation of the file.

Die Handhabung einer Feile muß unterschiedliche Anforderungen erfüllen. Feilen ab einer bestimmten Größe werden üblicherweise mit beiden Händen gehandhabt, wobei die eine Hand am Griff anfaßt. Dabei muß die Feile mit den Händen gesteuert werden, d.h. es muß eine bestimmte Orientierung der Feile, üblicherweise einer Bearbeitungsfläche der Feile, vorgegeben werden. Die Feile muß in ihrer Winkelstellung bzgl. dreier aufeinander senkrechter Achsen positioniert werden. Zusätzlich muß aber noch die eigentliche Feilbearbeitung durchgeführt werden, bei der während der Bewegung der Feile eine Kraft ausgeübt werden muß. Diese Kraft muß einmal in Bewegungsrichtung, üblicherweise der Vorschubrichtung, und aber auch in einer Richtung senkrecht zur Bearbeitungsfläche aufgebracht werden. Diesen unterschiedlichen Anforderungen werden die zur Zeit verwendeten Feilenhefte nicht gerecht.The handling of a file must meet different requirements. Files of a certain size are usually handled with both hands, with one hand on the handle. The file must be controlled by hand, i.e. a certain orientation of the file, usually a processing area of the file, must be specified. The file must be positioned in its angular position with respect to three mutually perpendicular axes. In addition, however, the actual file processing still has to be carried out, in which a force has to be exerted during the movement of the file. This force must be applied once in the direction of movement, usually the feed direction, but also in a direction perpendicular to the machining surface. The file booklets currently used do not meet these different requirements.

Der Erfindung liegt die Aufgabe zugrunde, ein Feilenheft zu schaffen, das den Bedürfnissen des Benutzers einer Feile besser angepaßt ist.The invention has for its object to provide a file handle that is better adapted to the needs of the user of a file.

Zur Lösung dieser Aufgabe schlägt die Erfindung ein Feilenheft mit den Merkmalen des Anspruchs 1 vor. Durch die Kugelform wird eine gut im Handteller liegende Form geschaffen, die zu einer Verringerung der Flächenbelastung und damit zu einem besseren und ermüdungsfreieren Einwirken der Hand auf die Feile führt. Aufgrund der Kugelform kann ein Druck nicht nur in Längsrichtung der Feile, also beim Schieben, sondern auch schräg zu dieser Richtung ausgeübt werden, so daß sich ein gutes Feilergebnis erzielen läßt.To achieve this object, the invention proposes a file book with the features of claim 1. The spherical shape creates a shape that lies well in the palm of the hand, which leads to a reduction in the surface load and thus to a better and fatigue-free action of the hand on the file. Due to the spherical shape, pressure can be exerted not only in the longitudinal direction of the file, ie when pushing, but also at an angle to this direction, so that a good filing result can be achieved.

Es ist vorgesehen, daß das freie Ende des Feilenhefts die Form einer mehr als halben Kugel aufweist. Dies bedeutet, daß sich der Querschnitt des Feilenhefts nach dem Ende verringert, so daß das Ende einen größeren Teil als eine Halbkugel bildet. Dies schafft eine Anlagefläche für die Fingerspitze des kleinen und Ringfingers.It is envisaged that the free end of the file handle has the shape of more than half a ball. This means that the cross section of the file handle decreases after the end, so that the end forms a larger part than a hemisphere. This creates a contact surface for the fingertip of the little and ring finger.

Es ist vorgesehen, daß unmitttelbar vor dem teilkugelförmigen Ende des Hefts eine Querschnittseinschnürung angeordnet ist. Auch diese kann zur Anlage des kleinen Fingers dienen. Die Griffigkeit des Heftes wird dadurch vergrößert. Dies ist insbesondere bei der Rückwärtsbewegung, also dem Ziehen der Feile von Wichtigkeit, da die Feile hier dann besser mitgenommen werden kann.It is provided that a cross-sectional constriction is arranged immediately in front of the partially spherical end of the booklet. This can also be used to place the little finger. This increases the grip of the booklet. This is particularly important when moving backwards, i.e. when pulling the file, since the file can then be carried more easily.

Bei fast allen Arten von Feilen, allenfalls mit Ausnahme einer Rundfeile, muß während des Feilens eine bestimmte Orientierung der Feile durchgeführt werden. Um diese Möglichkeit zu verbessern, ist der Querschnitt des Hefts von seinem feilenseitigen Ende bis zu der Endeinschnürung vor der Kugel mehreckig mit abgerundeten Kanten bzw. Ecken ausgebildet. Es fällt dem Benutzer aufgrund der mehrkantigen Form leichter, die Orientierung der Feile zu kontrollieren.With almost all types of files, except possibly a round file, a certain orientation of the file must be carried out during the file. In order to improve this possibility, the cross section of the booklet is polygonal with rounded edges or corners from its file-side end to the end constriction in front of the ball. The polygonal shape makes it easier for the user to control the orientation of the file.

In Weiterbildung der Erfindung kann vorgesehen sein, daß an der Stelle des lokalen Querschnittmaximums der Durchmesser des Hefts etwa dem Durchmesser des teilkugelförmigen Endes gleich ist. Diese Stelle des Durchmessermaximums liegt dabei erfindungsgemäß etwa in der Mitte der Längserstreckung des Heftes. Damit wird eine gute Lage des Griffes in der geschlossenen Hand erreicht. Diese gute Grifflage in der Hand ist für die Positionierung der Feile von Wichtigkeit.In a further development of the invention it can be provided that the diameter of the booklet is approximately equal to the diameter of the part-spherical end at the location of the local cross-sectional maximum. According to the invention, this point of the maximum diameter lies approximately in the middle of the longitudinal extent of the booklet. This ensures a good position of the handle in the closed hand. This good grip position in the hand is important for the positioning of the file.

In Weiterbildung kann vorgesehen sein, daß der Querschnitt des Hefts von der Stelle des Querschnittmaximums bis zu der vorderen Einschnürung wieder abnimmt.In a further development it can be provided that the cross section of the booklet decreases again from the point of the maximum cross section to the front constriction.

Die Einschnürung dient zum Einlegen des Daumens. Die Erfindung schlägt nun vor, die an sich bekannte Einschnürung wesentlich deutlicher auszubilden, wobei beispielsweise mit Vorteil der größte Durchmesser um ca. 40 bis 50 % größer ist als der kleinste Durchmesser des Hefts.The constriction is used to insert the thumb. The invention now proposes to make the constriction known per se much clearer, for example the largest diameter advantageously being approximately 40 to 50% larger than the smallest diameter of the booklet.

Erfindungsgemäß kann vorgesehen sein, daß der maximale Durchmesser des Hefts mindestens etwa ein Viertel der Länge des Hefts beträgt.According to the invention it can be provided that the maximum diameter of the booklet is at least about a quarter of the length of the booklet.

In Weiterbildung kann vorgesehen sein, daß eine der Begrenzungsflächen des mehrkantigen Hefts parallel zu einer Arbeitsfläche der Feile verläuft.In a further development it can be provided that one of the boundary surfaces of the polygonal booklet runs parallel to a working surface of the file.

Further features, details and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention and from the drawing. Here show:
Fig. 1
a side view of a file handle proposed by the invention;
Fig. 2
schematically an end view showing the mutual orientation of the bounding surfaces of the booklet and the surfaces of the file.

Das in der Fig. 1 dargestellte Feilenheft beginnt im Bereich seines freien Endes 11 mit einer Teilkugelform, die sich über einen senkrecht zur Längsachse des Hefts verlaufenden Äquator 12 bis zu einer Einschnürung 13 fortsetzt. Von dieser Einschnürung 13 an wird die Querschnittsform von der Kreisform zu einer Mehrkantform, siehe auch Fig. 2. Gleichzeitig vergrößert sich der Querschnitt von der Einschnürung 13 bis etwa zu der Mitte der Längserstreckung des Heftes, wo eine Stelle 14 maximalen Durchmessers erreicht wird. An dieser Stelle ist der Durchmesser des Heftes praktisch gleich groß wie am Äquator 12 des kugelförmigen Endes. Weiter zum gegenüberliegenden vorderen Ende 15 des Hefts fortschreitend verringert sich der Querschnitt des Hefts wieder, bis an einer Stelle etwa im vorderen Drittel bis Viertel des Hefts eine weitere Einschnürung 16 erreicht wird. Von dieser Einschnürung 16 an vergrößert sich der Querschnitt wieder bis zum vorderen Ende 15.The file handle shown in FIG. 1 begins in the region of its free end 11 with a partial spherical shape, which continues through an equator 12 running perpendicular to the longitudinal axis of the handle to a constriction 13. From this constriction 13 on, the cross-sectional shape changes from a circular shape to a polygonal shape, see also FIG. 2. At the same time, the cross-section increases from the constriction 13 to approximately the middle of the longitudinal extent of the booklet, where a point 14 of maximum diameter is reached. At this The diameter of the booklet is practically the same size as at the equator 12 of the spherical end. Continuing to the opposite front end 15 of the booklet, the cross section of the booklet is reduced again until a further constriction 16 is reached at a point approximately in the front third to quarter of the booklet. From this constriction 16, the cross section increases again to the front end 15.

Vom vorderen Ende 15 aus erstreckt sich die eigentliche Feile 17, die in Fig. 1 nur angedeutet ist.The actual file 17 extends from the front end 15 and is only indicated in FIG. 1.

Mit Ausnahme des kugelförmigen Endes ist die Querschnittsform von einem regelmäßigen Vieleck, im dargestellten Beispiel einem Achteck, gebildet. Die einzelnen Flächen 18 der Außenseite des Hefts Verden durch Kanten 19 voneinander getrennt, die abgerundet verlaufen.With the exception of the spherical end, the cross-sectional shape is formed by a regular polygon, in the example shown an octagon. The individual surfaces 18 of the outside of the booklet Verden are separated from one another by edges 19 which are rounded.

Wie sich aus Fig. 2 ergibt, verläuft jeweils die obere und untere Fläche des Hefts in der dargestellten Stellung parallel zu der ebenen Arbeitsfläche 20 der Halbrundfeile. Der Benutzer der Feile hat daher in der Hand ein gewisses Gefühl dafür, wo seine Arbeitsfläche liegt und wie sie orientiert ist.As can be seen from FIG. 2, the upper and lower surfaces of the booklet in the position shown run parallel to the flat working surface 20 of the semicircular file. The user of the file therefore has a certain feeling in his hand for where his work surface is and how it is oriented.

Wenn man annimmt, daß bei der Darstellung der Fig. 1 die Arbeitsfläche 20 auf der Unterseite der Feile ist, so kann der Benutzer durch Angreifen an dem Heft eine Kraft sowohl in Vorwärtsrichtung als auch in Abwärtsrichtung auf das Heft ausüben, anders ausgedrückt auch eine Kraft schräg zur Längsachse. Die Richtung dieser Kraft ist in weiten Grenzen veränderbar, wobei in allen diesen Richtungen der Vorteil einer gleichmäßigen Kraftverteilung auf eine große Fläche im Handteller gegeben ist. Die Hand ermüdet also langsamer. Beim Zurückziehen der Feile können sich der kleine und der Ringfinger an der im Endbereich gebildeten Einschnürung 13 abstützen, wobei gleichzeitig auch die Vorderfinger der Hand in der vorderen Einschnürung 16 liegen und die Feile führen können. Aufgrund der von der Kreisform abweichenden Querschnittsform des kantigen Teils des Heftes kann der Benutzer auch gut Drehmomente auf die Feile ausüben, was sowohl zur Orientierung der Feile als auch zur Ausübung von ungleichmäßigem Druck erforderlich sein kann.If it is assumed that the work surface 20 is on the underside of the file in the illustration of FIG. 1, the user can exert a force in both forward and downward direction on the handle by gripping the handle, in other words also a force obliquely to the longitudinal axis. The direction of this force can be changed within wide limits, with the advantage of uniform force distribution over a large area in the palm of the hand in all of these directions. The hand tired more slowly. When the file is withdrawn, the small and the ring fingers can be on the constriction 13 formed in the end region support, the front fingers of the hand also lying in the front constriction 16 and being able to guide the file. Due to the cross-sectional shape of the angular part of the handle deviating from the circular shape, the user can also exert good torques on the file, which can be necessary both for orienting the file and for exerting uneven pressure.
