At the outer — in FIG. 3: lower — end of the arms 11 connected to the webs 5 and 6, the likewise outer — in FIGS. 1 to 3: likewise lower — ends of the webs 2 and 3 are articulated. Therefore, if in the following it is mentioned that the outer ends of the webs 2, 3 are articulated to the outer ends of the webs 5, 6, the outrigger 11 are also considered to be components of the webs 5, 6.

This is thus with its head part 24 against the bottom part 3 '(see FIG. 4) of the web which is also U-shaped in cross section (see FIG. 4) 3. These parts are not all shown in full in Figure 3, as the figure would otherwise be overloaded, but it results from Figures 4, 5 and 6.

  • Figure 8 shows the same view as Figure 7, but with the difference that the disc 9 has been removed. It can be seen from this that the circularly widened region 31 of the web 2, which is hidden behind the disk 9 in FIG. 7, is provided with two bores 32, 33; Furthermore, the circular region 31 is provided with a quarter-circular groove 34. If the web 2 is now folded relative to the web 3 and thus also the disk 9 fixed to the web 3 relative to the web 2, the raised portion 29 extends in the folded parallel position of the webs 2, 3 with respect to one another (as in FIGS. 1 to 4) in the opening 32. In the unfolded (operating) position of the punch - as in Figures 5 to 8 - the elevation 29 presses into the bore 33. The transition is brought about by the fact that the leaf spring 28 is so far from the Area 21 of the web 2 lifts that the elevation 29 is released and can rotate relative to the web 2.
  • the movement of the webs 2, 3 against one another is limited in that in one position the elevation 30 (see FIG. 10) bears against the left end 34 'of the groove 34. In the other, ie the folded position, of the webs 2, 3, the elevation 30 bears against the right end 34 "of the groove 34. In this way it is also ensured that the desired unfolding or spreading of the two webs of the parts 1, 4 - namely by 90 * - is observed, which must correspond to a certain standardized measure.

Abstract

Il est décrit un perforateur pliant. La partie supérieure (1) et la partie inférieure (4) sont constituées chacune de 2 traverses (2, 3) et (5, 6). Les extrémités des traverses (2, 3) sont articulées aux extrémités des traverses (5, 6) (axes de rotation 12, 13) constituées par les bras (11). Les traverses (2, 3) et (5, 6) sont reliées entre elles de manière pliable. Dans une position (figure 1-4), les traverses (2, 3) de la partie supérieure (1) et (5, 6) de la partie inférieure (4) sont parallèles entre elles. Ceci est la position repliée. Dans l'autre position, les traverses (2, 3) et (5, 6) sont dépliées l'une par rapport à l'autre. C'est dans ce cas que les axes de rotation (12, 13) sont alignés. Le perforateur se déplie; il est alors en position de fonctionnement.There is described a folding perforator. The upper part (1) and the lower part (4) each consist of 2 crosspieces (2, 3) and (5, 6). The ends of the crosspieces (2, 3) are articulated at the ends of the crosspieces (5, 6) (axes of rotation 12, 13) formed by the arms (11). The crosspieces (2, 3) and (5, 6) are folded together. In one position (Figure 1-4), the crosspieces (2, 3) of the upper part (1) and (5, 6) of the lower part (4) are parallel to each other. This is the stowed position. In the other position, the crosspieces (2, 3) and (5, 6) are unfolded relative to each other. It is in this case that the axes of rotation (12, 13) are aligned. The perforator unfolds; it is then in the operating position.

Der Locher ist in den Figuren 1 bis 3 im zusammengefalteten Zustand gezeigt, in dem man ihn leicht in eine Jacken- oder Hosentasche stecken kann. In der Draufsicht (Figur 1) sieht man die beiden das Oberteil 1 bildenden Stege 2 und 3; in der Ansicht von unten (Figur 2) sieht man die beiden das Unterteil 4 bildenden Stege 5 und 6. Die Stege 2 und 3 sind miteinander über eine Drehverbindung, die durch die Schraube 7 (Fig. 3) gebildet wird, faltbar verbunden. Die Stege 5 und 6 sind miteinander über eine Drehverbindung, die durch die Schraube 8 (Fig. 2, Fig. 3) gebildet wird, drehbar verbunden. Diese drehbare Verbindung gestattet eine gegenseitige Drehung der Stege 2 , 3 bzw. 5, 6 gegeneinander, dies jedoch nur in winkelmäßig auf 90° begrenztem Maße und in einer Ebene; aus diesem Grunde wird im folgenden davon gesprochen, daß die Stege 2 , 3 bzw. 5, 6 gegeneinander "faltbar" sind. Wie aus Figur 3 zu ersehen ist, ist an der Stelle der Faltverbindung der Stege 2 und 3 mit diesen eine weitere Scheibe 9 verbunden, die derart in den Steg 3 eingesetzt ist, daß sich diesem gegenüber nicht verdrehen kann und die dazu dient, die Stege 2 und 3 sowohl in der in den Figuren 1 bis 3 gezeigten zusammengefalteten Stellung, als auch in einer auseinandergefalteten Stellung gegeneinander festzulegen.The punch is shown in Figures 1 to 3 in the folded state, in which it can easily be put in a jacket or trouser pocket. The top view (FIG. 1) shows the two webs 2 and 3 forming the upper part 1; the view from below (FIG. 2) shows the two webs 5 and 6 forming the lower part 4. The webs 2 and 3 are foldably connected to one another by means of a rotary connection which is formed by the screw 7 (FIG. 3). The webs 5 and 6 are rotatably connected to one another via a rotary connection which is formed by the screw 8 (FIG. 2, FIG. 3). This rotatable connection allows a mutual rotation of the webs 2, 3 and 5, 6 against each other, but only in angularly limited to 90 ° and in one plane; for this reason it is said in the following that the webs 2, 3 and 5, 6 are "foldable" against each other. As can be seen from Figure 3, at the location of the folding connection of the webs 2 and 3 with this another disc 9 is connected, which is inserted into the web 3 in such a way that it cannot rotate relative to it and which serves the webs 2 and 3 both in the folded position shown in Figures 1 to 3, as well as in an unfolded position to fix against each other.
An dem Steg 5 - und (in Fig. 3) dahinter entsprechend am Steg 6 - sind mittels Schrauben 10 je treppenför ig gekröpfte Ausleger 11 angebracht. Zwischen den freien Enden der Ausleger 11 und der Stege 5 bzw. 6 ergeben sich die Schlitze 22 und 22' zum Einlegen eines zu lochenden Blattes 23 (vgl. auch Fig. 4, 5 , 6). Am äußeren - in Figur 3: unteren - Ende der mit den Stegen 5 bzw. 6 verbundenen Ausleger 11 sind dann die ebenfalls äußeren - in den Figuren 1 bis 3: ebenfalls unteren - Enden der Stege 2, bzw. 3 angelenkt. Wenn daher im folgenden davon die Rede ist, daß die äußeren Enden der Stege 2, 3 an den äußeren Enden der Stege 5, 6 angelenkt sind, so werden dabei die Ausleger 11 mit als Bestandteile der Stege 5, 6 betrachtet. Die Anlenkung erfolgt mittels Drehachsen 12, 13, die, wie aus Figur 4 ersichtlich, in die Seitenteile der U-förmigen Stege 2 bzw. 3 eingeschraubt sind.On the web 5 - and (in Fig. 3) behind it on the web 6 - are attached by means of screws 10 each stepped cantilever arm 11. Between the free ends of the arms 11 and the webs 5 and 6 there are the slots 22 and 22 'for inserting a sheet 23 to be punched (cf. also FIGS. 4, 5, 6). At the outer — in FIG. 3: lower — end of the arms 11 connected to the webs 5 and 6, the likewise outer — in FIGS. 1 to 3: likewise lower — ends of the webs 2 and 3 are articulated. Therefore, if in the following it is mentioned that the outer ends of the webs 2, 3 are articulated to the outer ends of the webs 5, 6, the outrigger 11 are also considered to be components of the webs 5, 6. The articulation is carried out by means of axes of rotation 12, 13 which, as can be seen from FIG. 4, are screwed into the side parts of the U-shaped webs 2 and 3, respectively.
Wie aus Figur 3 zu ersehen, befindet sich an dem Steg 5 oben eine zur Ebene der Stege quer angeordnete Lasche 14 mit einer Öffnung 15. Diese Lasche ist am Steg 5 befestigt oder mit ihm einteilig ausgebildet. Die Lasche 15 weist einen Schlitz 16 auf, in den in der zusammengefalteten Stellung (Figur 1 bis 4) ein Nocken 17 hineinragt. Der Nocken 17 ist am Steg 2 befestigt. Der Steg 5, verbunden mit Lasche 14 gehört zum Unterteil 4. Der Steg 2, an dem der Nocken 17 befestigt ist, gehört zum Oberteil 1. Durch die Festlegung des Nockens 17 im Schlitz 16 bzw. an dessen einer Seite ist somit in dieser zusammengefalteten Stellung (Figur 1 bis 4) - das Oberteil 1 gegenüber dem Unterteil 4 derart verriegelt, daß die beiden durch die zwischen ihnen wirksame Feder 18 nicht auseinander gedrückt werden können.As can be seen from FIG. 3, on the web 5 there is a tab 14 which is arranged transversely to the level of the webs and has an opening 15. This tab is fastened to the web 5 or formed in one piece with it. The tab 15 has a slot 16 into which a cam 17 projects in the folded position (FIGS. 1 to 4). The cam 17 is attached to the web 2. The web 5, connected to the tab 14 belongs to Lower part 4. The web 2, on which the cam 17 is attached, belongs to the upper part 1. By fixing the cam 17 in the slot 16 or on one side, the upper part is thus in this folded position (FIGS. 1 to 4) 1 locked to the lower part 4 in such a way that the two cannot be pressed apart by the spring 18 acting between them.
Die Feder 18 ist in Figur 3 der Übersichtlichkeit halber lediglich angedeutet. Sie ist U-förmig ausgebildet. Ihr einer Schenkel 18' ist mit dem Bodenteil 5' (vgl. Fig.) des im Querschnitt U-förmigen Steges 5 fest verbunden. Der andere Schenkel 18" der Feder bildet das freie Ende und trägt den Lochstempel 19. Dieser wird somit mit seinem Kopfteil 24 gegen den Bodenteil 3' (vgl. Fig. 4) des im Querschnitt ebenfalls U-förmigen (vgl. Figur 4) Steges 3 gedrückt. Diese Teile sind in Figur 3 nicht alle voll dargestellt, da sonst die Figur überlastet würde. Es ergibt sich aber aus den Figuren 4, 5 und 6.The spring 18 is only indicated in Figure 3 for the sake of clarity. It is U-shaped. One of its legs 18 'is firmly connected to the base part 5' (see FIG.) Of the web 5 which is U-shaped in cross section. The other leg 18 "of the spring forms the free end and carries the punch 19. This is thus with its head part 24 against the bottom part 3 '(see FIG. 4) of the web which is also U-shaped in cross section (see FIG. 4) 3. These parts are not all shown in full in Figure 3, as the figure would otherwise be overloaded, but it results from Figures 4, 5 and 6.
wird nun der Locher auseinandergefaltet, d.h. die Stege 2, 6 von den Stegen 3, 5 in Richtung der Pfeile 21 (Fig. 1, 2) auseinandergefaltet, so ist die beschriebene Verriegelung der Nocke 17 im Schlitz 16 nicht mehr gegeben. Die Feder 18 drückt das Oberteil 1 vom Unterteil 4 weg, und zwar in Richtung der Pfeile 20 in Figur 2. Die äußeren Enden der Stege 2, 3 können sich also nun gegenüber den äußeren Enden der Stege 5, 6 drehen bzw. aufklappen (Fig. 5, 6). Voraussetzung dafür ist aber ferner, daß die Auffaltung soweit erfolgt, daß die Drehachsen 12, 13 miteinander fluchten. Dies ist aber der Fall, wenn man den Locher in Richtung der Pfeile 21 in Figur 1 und 2 derart auseinanderfaltet, daß die Stege 2, 3 und 5, 6 je miteinander einen Winkel von 90* bilden. Ist diese Stellung jedoch nicht gegeben, d.h. stehen die Drehachsen 12, 13 nicht fluchtend zueinander, so kann sich der Locher nicht derart "auffalten".If the punch is now unfolded, ie the webs 2, 6 are unfolded by the webs 3, 5 in the direction of the arrows 21 (FIGS. 1, 2), the locking of the cam 17 in the slot 16 is no longer given. The spring 18 presses the upper part 1 away from the lower part 4, specifically in the direction of the arrows 20 in FIG. 2. The outer ends of the webs 2, 3 can thus now rotate or open relative to the outer ends of the webs 5, 6 (FIG 5, 6). However, a prerequisite for this is that the unfolding takes place to such an extent that the axes of rotation 12, 13 are aligned with one another. However, this is the case if the perforator is unfolded in the direction of the arrows 21 in FIGS. 1 and 2 in such a way that the webs 2, 3 and 5, 6 each form an angle of 90 * with one another. However, if this position is not given, ie the axes of rotation 12, 13 are not aligned with each other, the punch cannot "unfold" in this way.
Die Ausbildung der Feder 18 ist am besten aus Figur 6 ersichtlich. Sie ist mit dem Schenkel 18', wie bereits erwähnt, am Bodenteil 5' des Schenkels 5 befestigt, z.B. angelötet oder verschraubt.The design of the spring 18 is best seen in Figure 6. As already mentioned, it is attached with the leg 18 'to the bottom part 5' of the leg 5, e.g. soldered or screwed.
Wie auf der rechten Seite von Figur 6 gestrichelt dargestellt ist, weist der Ausleger 11 eine Führungsöffnung 25 auf, die derart angeordnet ist, daß der Lochstempel 19, wenn er herabgedrückt wird, in ihr geführt wird. Mit der Führungsöffnung 25 fluchtend, weist das äußere Ende des Steges 6 eine Stempelöffnung 26 auf, in die der Lochstempel 19 bei seiner Abwärtsbewegung hineingedrückt wird, und zwar derart, daß seine Schneidkanten in bekannter Weise ein in den Schlitz 21 eingelegtes Blatt 23 lochen. Die Herabbewegung des Lochstempelε 19 wird dadurch bewirkt, daß man den Locher an der Stelle, an der die Stege 2, 3 des Oberteils 1 und 5, 6 des Unterteils 4 aneinander drehbar angelenkt sind, d.h. in Figur 6 links, - bei eingelegtem Blatt 23 - zwischen Daumen und Zeigefinger erfaßt und in Richtung der Pfeile 27 zusammendrückt. Dann drückt der Bodenteil 2' des im Querschnitt U-förmig ausgebildeten Steges 2 auf die Kopffläche 24 des Lochεte pels 9. Dadurch werden die Federn 18 zusammengedrückt und dadurch wiederum die Lochstempel 19 abwärts bewegt.As shown in dashed lines on the right-hand side of FIG. 6, the boom 11 has a guide opening 25 which is arranged such that the punch 19, when it is pressed down, is guided in it. Aligned with the guide opening 25, the outer end of the web 6 has a punch opening 26 into which the punch 19 is pressed during its downward movement, in such a way that its cutting edges punch a sheet 23 inserted into the slot 21 in a known manner. The downward movement of the punch 19 is effected in that the punch is pivoted at the point at which the webs 2, 3 of the upper part 1 and 5, 6 of the lower part 4 are pivoted to one another, i.e. in Figure 6 left, - with sheet 23 inserted - between thumb and forefinger and pressed in the direction of arrows 27. Then the bottom part 2 'of the cross-sectionally U-shaped web 2 presses onto the head surface 24 of the hole element 9. This compresses the springs 18 and in turn moves the hole punches 19 downward.
Figur 7 zeigt in vergrößerter Darstellung die Faltverbindung der Stege 2 und 3 mit der Scheibe 9. Die Scheibe 9 ist - wie bereits erwähnt - mittels der Schraube 8 mit den Stegen 2, 3 an deren Drehpunkt verbunden. Sie weist einen Lappen 9' auf, der derart zwischen den beiden Schenkeln des im Querschnitt U-förmigen Steges 3 eingelegt ist, daß sich die Scheibe 9 gegenüber dem Steg 3 nicht verdrehen kann. Die Scheibe 9 weist ferner, wie aus den Figuren 6 und 10 zu ersehen ist, einen Schlitz 27 auf, der um die Schraube 8 einen viertelkreisförmigen Verlauf hat. Das eine Ende des Schlitzes endet stumpf innerhalb der Scheibe 9; das andere Ende öfnet sich radial nach außen. Auf diese Weise entsteht eine Blattfeder 28 mit der Form eines Viertelkreissegmentes, deren vorderes freies Ende 28' gegenüber dem Steg 2 federn kann. Verallgemeinert man diese Situation, so ist am Steg 3 - mittels Lappen 9' und Schraube 8 - eine Blattfeder 28 festgelegt, deren freies Ende 28' gegen den Steg 2 drückt.FIG. 7 shows an enlarged view of the folded connection of the webs 2 and 3 to the disk 9. The disk 9 is - as already mentioned - connected to the webs 2, 3 at their pivot point by means of the screw 8. It has a tab 9 'which is inserted between the two legs of the cross-sectionally U-shaped web 3 such that the disk 9 cannot twist relative to the web 3. The disc 9 also has, as can be seen from FIGS. 6 and 10, a slot 27 which has a quarter-circular course around the screw 8. One end of the slot ends bluntly within the disc 9; the other end opens radially outwards. In this way, a leaf spring 28 is formed with the shape of a quarter circle segment, the front free end 28 'of which can spring relative to the web 2. If this situation is generalized, a leaf spring 28 is fixed to the web 3 - by means of tab 9 'and screw 8 - the free end 28' of which presses against the web 2.
Figur 9 zeigt die Scheibe 9 von derselben Seite wie Figur 7, jedoch als Einzelteil. Figur 10 zeigt die Scheibe 9 von der Rückseite. Daraus ist ersichtlich, daß am vorderen Ende 28-* der Blattfeder 28 - dem verbreiterten Bereich 31 des Steges 2 zugewandt - eine kleine stift- oder warzenförmige Erhebung 29 angebracht ist.Figure 9 shows the disc 9 from the same side as Figure 7, but as a single part. Figure 10 shows the disc 9 from the rear. From this it can be seen that at the front end 28- * of the leaf spring 28 - facing the widened region 31 of the web 2 - a small pin or wart-shaped elevation 29 is attached.
Figur 8 zeigt dieselbe Ansicht wie Figur 7, jedoch mit dem Unterschied, daß die Scheibe 9 entfernt worden ist. Es zeigt sich daraus, daß der kreisförmig verbreiterte Bereich 31 des Steges 2, der in Figur 7 hinter der Scheibe 9 verborgen liegt, mit zwei Bohrungen 32, 33 versehen ist; ferner ist der kreisförmige Bereich 31 mit einer viertelkreisförmigen Nut 34 versehen. Faltet man nun den Steg 2 gegenüber dem Steg 3 und damit auch die am Steg 3 festgelegte Scheibe 9 gegenüber dem Steg 2, so erstreckt sich in zusammengefalteter paralleler Position der Stege 2, 3 zueinander (wie in den Figuren 1 bis 4) die Erhebung 29 in die Öffnung 32. In der auseinandergefalteten (Betriebs-)Stellung des Lochers - wie in den Figuren 5 bis 8 - drückt sich die Erhebung 29 in die Bohrung 33. Der Übergang wird dadurch bewirkt, daß sich bei leichter Kraftanwendung die Blattfeder 28 soweit vom Bereich 21 des Steges 2 abhebt, daß die Erhebung 29 freigegeben wird und sich gegenüber dem Steg 2 verdrehen kann.Figure 8 shows the same view as Figure 7, but with the difference that the disc 9 has been removed. It can be seen from this that the circularly widened region 31 of the web 2, which is hidden behind the disk 9 in FIG. 7, is provided with two bores 32, 33; Furthermore, the circular region 31 is provided with a quarter-circular groove 34. If the web 2 is now folded relative to the web 3 and thus also the disk 9 fixed to the web 3 relative to the web 2, the raised portion 29 extends in the folded parallel position of the webs 2, 3 with respect to one another (as in FIGS. 1 to 4) in the opening 32. In the unfolded (operating) position of the punch - as in Figures 5 to 8 - the elevation 29 presses into the bore 33. The transition is brought about by the fact that the leaf spring 28 is so far from the Area 21 of the web 2 lifts that the elevation 29 is released and can rotate relative to the web 2.
Die Bewegung der Stege 2, 3 gegeneinander ist dadurch begrenzt, daß in der einen Stellung die Erhebung 30 (vgl. Figur 10) am linken Ende 34' der Nut 34 anliegt. In der anderen, d.h. der zusammengefalteten Stellung, der Stege 2, 3 liegt die Erhebung 30 am rechten Ende 34" der Nut 34 an. Auf diese Weise ist also auch gewährleistet, daß die gewünschte Auffaltung oder Spreizung der beiden Stege der Teile 1, 4 - nämlich um 90* - sicher eingehalten wird. Diese muß einem bestimmten genormten Maß entsprechen.The movement of the webs 2, 3 against one another is limited in that in one position the elevation 30 (see FIG. 10) bears against the left end 34 'of the groove 34. In the other, ie the folded position, of the webs 2, 3, the elevation 30 bears against the right end 34 "of the groove 34. In this way it is also ensured that the desired unfolding or spreading of the two webs of the parts 1, 4 - namely by 90 * - is observed, which must correspond to a certain standardized measure.
Die Figuren 11 bis 13 zeigen eine Klammer 40 und ihre Anbringung in der Oberseite des faltbaren Lochers nach Figur 1 bis 10. Die Klammer 40 ist an der Stelle der Drehverbindungen der Stege 2, 3 angebracht. Mit Hilfe des freistehenden Endes 41, das federnd gegen die vorne liegenden Stege 2, 3 drückt, kann man den Locher in der'Brusttasche eines Hemdes oder der Innentasche eine Jackets fest-klippen. Diese Klammer 40 stellt somit einen Klipp dar, wie er auch bei Bleistiften, Kugelschreibern, etc. verwendet wird, der jedoch dem speziellen zweck des vorliegenden Falles besonders angepaßt ist. Der Klipp weist außerdem eine pfeilförmige Öffnung 42 auf. Sorgt man dafür, daß die Klammer 40 sich in der Position der Winkelhalbierenden zwischen den Stegen 2, 3 in deren aufgeklappter und ausgefalteter Stellung befindet, dient die pfeilförmige Öffnung 42 dazu, eine bedruckte oder durch Faltung markierte Mittellinie eines Blattes 23 so im Locher zu positionieren, daß die zwei Löcher symmetrisch zur Mittellinie gelocht werden.FIGS. 11 to 13 show a clip 40 and its attachment in the top of the foldable hole punch according to FIGS. 1 to 10. The clip 40 is attached to the location of the rotary connections of the webs 2, 3. With the help of the free end 41 which resiliently presses against the front lying webs 2, 3, one can determined the punch Cliffs in the 'breast pocket of a shirt or the inside pocket of a jacket. This clip 40 thus represents a clip, as is also used in pencils, ballpoint pens, etc., which is, however, particularly adapted to the special purpose of the present case. The clip also has an arrow-shaped opening 42. If you ensure that the clamp 40 is in the position of the bisector between the webs 2, 3 in their opened and unfolded position, the arrow-shaped opening 42 serves to position a printed or fold-marked center line of a sheet 23 in the hole that the two holes are punched symmetrically to the center line.
Die Klammer 40 ist, wie am besten aus dem Querschnitt nach Figur 13 ersichtlich, U-förmig gebogen, wobei der untere Schenkel 43 kürzer als der obere Schenkel 44 ausgebildet ist. Die Klammer 40 ist mittels der Schraube 44, die anstelle der Schraube 8 in den Figuren 1 bis 10 vorgesehen ist, mit den Stegen 2, 3 und der Scheibe 9 verschraubt. Aus einem Einschnitt 46 im oberen Schenkel 44 ist ein kleiner Lappen 47 ausgestanzt und in der aus Figur 11 und 13 ersichtlichen Weise nach unten abgebogen und mit einer kleinen Kröpfung 48 versehen, mit der er die beiden miteinander verbundenen Bereiche der Stege 2, 3 und die Scheibe 9 übergreift. Gleichzeitig weist das in Figur 13 untere Ende des unteren Schenkels 43 eine Erhebung 49 auf, die in der Arbeitsstellung des Lochers (Figur 5 bis 8) in eine Öffnung 50 im darunterliegenden Bereich 31 des Steges 2 einschnappt. Faltet man den Locher zusammen (Figur 1 bis 4), dann kann man manuell auch die Klammer 40 so verdrehen, daß nunmehr die Erhebung 49 in die Öffnung 51 einschnappt und damit die Klammer 40 parallel zu den Schenkeln 2, 3 ausgerichtet ist. As best seen in the cross section according to FIG. 13, the clamp 40 is bent in a U-shape, the lower one Leg 43 is shorter than the upper leg 44. The clamp 40 is screwed to the webs 2, 3 and the washer 9 by means of the screw 44, which is provided instead of the screw 8 in FIGS. 1 to 10. A small tab 47 is punched out of an incision 46 in the upper leg 44 and bent downwards in the manner shown in FIGS. 11 and 13 and provided with a small offset 48 with which it connects the two interconnected regions of the webs 2, 3 and Disc 9 overlaps. At the same time, the lower end of the lower leg 43 in FIG. 13 has an elevation 49 which, in the working position of the punch (FIGS. 5 to 8), snaps into an opening 50 in the region 31 of the web 2 below. If you fold the punch together (FIGS. 1 to 4), you can also manually turn the clamp 40 so that the elevation 49 now snaps into the opening 51 and the clamp 40 is thus aligned parallel to the legs 2, 3.
