Definitions
- the invention relates to a letter punch with a lower part, a pivotally mounted on lateral bearing blocks of the lower part, acting on the punch on the lower part acting against the restoring force of a spring pressure lever, the pressure lever two laterally bent down, the bearing blocks overlapping on the outside bearing tabs and one on the front Pressure lever in the area between the bearing tabs bent down, under the action of the restoring force of the spring against the stop edges on the bearing blocks has apron.
- a letter punch has become known to the experts before the priority date of this application.
- the invention is based on the object, the known letter punch the above Type to improve in such a way that a risk of injury is avoided even with improper handling of the punch hole.
- the solution according to the invention is based on the knowledge that when the pressure lever is actuated, no gap which is accessible from the outside may occur, into which hand parts can inadvertently penetrate even when handled improperly.
- the stop edges are arranged on thin-walled cantilevers of the bearing blocks which are aligned parallel to the bearing flaps and that the apron has a bend on its side edges near its lower edge which together with the adjacent bearing tab, a gap open towards the lower part for the engagement of the boom is limited.
- the stop edge can either be formed by an upward-facing step that abuts an upper boundary edge of the gap, which is preferably arranged on the apron, or by a front edge of the arm that abuts the apron in the region near the gap.
- cantilever arms which extend underneath the apron, are arranged on the bearing blocks, the upper edges of which are the stop edges form, while the apron has at the distance from its lower edge protruding stops for the upper edges of the boom. So that when the pressure lever is actuated over the entire swivel range between the apron and the boom, there is no gap into which a finger could be pinched, the booms have a partially cylindrical surface curvature that is coaxial with the swivel axis of the pressure lever, at least in their area overlapped, over the entire length Swivel path releases a constant gap of less than 4 mm.
- the apron is also formed in a shell-like manner on its inner surface facing the partially cylindrical arm part.
- the arrangement of the stops provided according to the second variant of the invention makes it possible to arrange in the area between the lower edge of the apron and the stops a transversely displaceable on the apron between two end positions, in one end position engaging in the swivel path of one of the upper boom edges, designed as a hold-down for the pressure lever .
- the stop slide can preferably be locked in a latching connection at least in the end position disengaged from the pivoting path of the boom.
- the stop slide is advantageously guided in a substantially horizontal elongated hole in the apron and has an actuating head which extends through the elongated hole to the end face of the punch.
- the distance between the apron and a cross bar covering the punch on the end face is selected at least finger width over the entire swivel range of the pressure lever. This ensures that accidental pinching of hand parts is avoided in this area as well.
- the sheet metal punch shown in FIGS. 1 and 2 essentially consists of a lower part 10, a bearing part 12 rigidly connected to the lower part and an on the bearing blocks 14 of the bearing part 12 about an axis 16 pivotally mounted pressure lever 18.
- In the bearing part 12 are also surrounded by a helical spring 20 perforated punches 22, which are pushed downward against the restoring force of the springs 20 when the pressure lever 18 is pushed down while penetrating the insertion slot 24 and a die opening 26 in the lower part 10.
- the pressure lever is automatically pivoted back into its starting position under the action of the springs 20.
- the pressure lever 18 has two laterally bent bearing tabs 28 which overlap the bearing blocks 14 on the outside. Furthermore, the pressure lever 18 is provided with a stop apron 30 which is bent downward on the end face and connects the two bearing lugs 28 to one another. In the vicinity of its side edges and in the area of its lower edge 32, the apron 30 has a flap-like bend 34 pointing backwards, which, together with the adjacent bearing tab 28, delimits a gap 38 which is open at the bottom and closed at the top by a punched edge 36 in the apron. A thin-walled arm 40 of the bearing block 14 engages in this gap and has a step 42 serving as a stop for the transverse edge 36 arranged on the skirt 30.
- an edge part of the arm 40 which engages under the apron 30 serves as a stop for the pressure lever. Since the width of the gap 38 can be made smaller than 4 mm, there is no danger that a finger is pinched between the stop edges. It is only important that the bend 34 is so long that the boom 40 still engages in the gap 38 even when the pressure lever 18 is depressed.
- the punching guides in the bearing part 12 are covered on the end face by a cross bar 43.
- the apron 30 and the crossbeam 43 are at least a finger-wide apart from one another in all swivel positions of the pressure lever 18.
- the lower part 10 and the bearing blocks 14 are integrally connected to one another, leaving the insertion slot 24 free.
- uprights 50 are arranged on the end faces, which reach under the apron 30 with their upper edge 52, which serves as a stop edge.
- the arms 50 have a part-cylindrical curvature coaxial to the pivot axis 16 in their part which engages under the skirt 30, while the skirt 30 on its side facing the arms 50 is formed accordingly bowl-shaped.
- the described arrangement of the stops of the cast hole punch according to FIGS. 3 and 4 is also suitable for accommodating an adjustable stop slide 56 in the area between the lower skirt edge 32 and one of the stop cams 54.
- a stop slide 56 which is arranged displaceably in a horizontal slot 58 of the apron 30 serves as a hold-down device for the pressure lever 18, which can be brought into engagement with the adjacent upper edge 52 of the jib, for example for transport or storage purposes.
- the stop slide 56 should preferably be lockable in a latching connection at least in the end position disengaged from the pivoting path of the boom 50 on the pressure lever 18.

Abstract
Description
Die Erfindung betrifft einen Brieflocher mit einem Unterteil, einem an seitlichen Lagerböcken des Unterteils schwenkbar gelagerten, auf am Unterteil verschiebbar geführte Lochstempel gegen die Rückstellkraft einer Feder einwirkenden Druckhebel, wobei der Druckhebel zwei seitlich nach unten gebogene, die Lagerböcke außenseitig überlappende Lagerlappen und eine stirnseitig am Druckhebel im Bereich zwischen den Lagerlappen nach unten gebogene, unter der Einwirkung der Rückstellkraft der Feder gegen Anschlagkanten an den Lagerböcken anschlagende Schürze aufweist. Ein derartiger Brieflocher ist der Fachwelt vor dem Prioritätstag dieser Anmeldung bekannt geworden.The invention relates to a letter punch with a lower part, a pivotally mounted on lateral bearing blocks of the lower part, acting on the punch on the lower part acting against the restoring force of a spring pressure lever, the pressure lever two laterally bent down, the bearing blocks overlapping on the outside bearing tabs and one on the front Pressure lever in the area between the bearing tabs bent down, under the action of the restoring force of the spring against the stop edges on the bearing blocks has apron. Such a letter punch has become known to the experts before the priority date of this application.
Bei Brieflochern dieser Art wird beim Niederdrücken des Druckhebels die Schürze von ihrer Anschlagkante abgehoben. Dabei bildet sich in der Regel ein von außen zugänglicher Spalt, in den vor allem bei unsachgemäßer Handhabung des Lochers ein Finger oder ein Handteil eindringen und dort beim anschließenden Zurückfedern des Druckhebels eingeklemmt werden kann. Im Hinblick auf die für das Zurückziehen der Lochstempel aus gelochten Papierstapeln erforderliche große Rückstellkraft besteht hierbei eine erhebliche Verletzungsgefahr, die dadurch noch verstärkt wird, daß die gegeneinander anschlagenden Locherteile oft recht scharfkantig ausgebildet sind.In the case of letter punches of this type, the apron is lifted off its stop edge when the pressure lever is depressed. As a rule, an externally accessible gap is formed, into which a finger or a hand part can penetrate, especially when the punch is handled improperly, and can be pinched there when the pressure lever springs back. With regard to the large restoring force required for retracting the punch from perforated paper stacks, there is a considerable risk of injury, which is exacerbated by the fact that the perforating parts which strike one another are often quite sharp-edged.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, die bekannten Brieflocher der eingangs angegebenen Art dahingehend zu verbessern, daß eine Verletzungsgefahr auch bei unsachgemäßer Handhabung des Brieflochers vermieden wird.Proceeding from this, the invention is based on the object, the known letter punch the above Type to improve in such a way that a risk of injury is avoided even with improper handling of the punch hole.
Die erfindungsgemäße Lösung geht von der Erkenntnis aus, daß beim Betätigen des Druckhebels kein von außen zugänglicher Spalt auftreten darf, in den auch bei unsachgemäßer Handhabung Handteile versehentlich eindringen können.The solution according to the invention is based on the knowledge that when the pressure lever is actuated, no gap which is accessible from the outside may occur, into which hand parts can inadvertently penetrate even when handled improperly.
Um dies zu erreichen, wird gemäß einer ersten, vor allem für Blechlocher geeigneten Erfindungsvariante vorgeschlagen, daß die Anschlagkanten an parallel zu den Lagerlappen ausgerichteten dünnwandigen Auslegern der Lagerböcke angeordnet sind und daß die Schürze an ihren Seitenrändern in der Nähe ihrer Unterkante eine Abbiegung aufweist, die gemeinsam mit dem benachbarten Lagerlappen einen zum Unterteil hin randoffenen Spalt für den Eingriff des Auslegers begrenzt. Die Anschlagkante kann dabei entweder durch eine nach oben weisende, gegen eine obere, vorzugsweise an der Schürze angeordnete Begrenzungskante des Spalts anschlagende Stufe oder durch eine im spaltnahen Bereich rückseitig gegen die Schürze anschlagende Stirnkante des Auslegers gebildet sein.In order to achieve this, it is proposed according to a first variant of the invention which is particularly suitable for sheet metal punches that the stop edges are arranged on thin-walled cantilevers of the bearing blocks which are aligned parallel to the bearing flaps and that the apron has a bend on its side edges near its lower edge which together with the adjacent bearing tab, a gap open towards the lower part for the engagement of the boom is limited. The stop edge can either be formed by an upward-facing step that abuts an upper boundary edge of the gap, which is preferably arranged on the apron, or by a front edge of the arm that abuts the apron in the region near the gap.
Gemäß einer zweiten, vor allem bei Gußlochern realisierbaren Erfindungsvariante sind an den Lagerböcken stirnseitig nach oben weisende die Schürze untergreifende Ausleger angeordnet, deren Oberkanten die Anschlagkanten bilden, während die Schürze im Abstand von ihrer Unterkante rückseitig überstehende Anschläge für die Oberkanten der Ausleger aufweist. Damit beim Betätigen des Druckhebels über den gesamten Schwenkbereich zwischen Schürze und Ausleger kein Spalt entsteht, in den ein Finger eingeklemmt werden könnte, weisen die Ausleger zumindest in ihrem von der Schürze übergriffenen Bereich eine zur Schwenkachse des Druckhebels koaxiale teilzylindrische Oberflächenkrümmung auf, die über den gesamten Schwenkweg einen konstanten Spalt von weniger als 4 mm freigibt. Eine weitere Verbesserung in dieser Hinsicht wird dadurch erzielt, daß auch die Schürze an ihrer dem teilzylindrischen Auslegerteil zugewandten Innenfläche schalenartig ausgebildet ist.According to a second variant of the invention, which can be implemented especially in the case of cast holes, cantilever arms, which extend underneath the apron, are arranged on the bearing blocks, the upper edges of which are the stop edges form, while the apron has at the distance from its lower edge protruding stops for the upper edges of the boom. So that when the pressure lever is actuated over the entire swivel range between the apron and the boom, there is no gap into which a finger could be pinched, the booms have a partially cylindrical surface curvature that is coaxial with the swivel axis of the pressure lever, at least in their area overlapped, over the entire length Swivel path releases a constant gap of less than 4 mm. A further improvement in this regard is achieved in that the apron is also formed in a shell-like manner on its inner surface facing the partially cylindrical arm part.
Die nach der zweiten Erfindungsvariante vorgesehene Anordnung der Anschläge ermöglicht es, im Bereich zwischen der Schürzenunterkante und den Anschlägen einen zwischen zwei Endstellungen quer an der Schürze verschiebbaren, in der einen Endstellung in den Schwenkweg einer der Auslegeroberkanten eingreifenden, als Niederhalter für den Druckhebel ausgebildeten Anschlagschieber anzuordnen. Um den Niederhalter nicht versehentlich während der Betätigung des Druckhebels auszulösen, ist der Anschlagschieber zumindest in der aus dem Schwenkweg des Auslegers ausgerückten Endstellung am Druckhebel vorzugsweise in einer Rastverbindung arretierbar. Der Anschlagschieber ist vorteilhafterweise in einem im wesentlichen horizontalen Langloch der Schürze geführt und weist einen durch das Langloch zur Stirnseite des Lochers hindurchgreifenden Betätigungskopf auf.The arrangement of the stops provided according to the second variant of the invention makes it possible to arrange in the area between the lower edge of the apron and the stops a transversely displaceable on the apron between two end positions, in one end position engaging in the swivel path of one of the upper boom edges, designed as a hold-down for the pressure lever . In order not to trigger the hold-down device accidentally during the actuation of the pressure lever, the stop slide can preferably be locked in a latching connection at least in the end position disengaged from the pivoting path of the boom. The stop slide is advantageously guided in a substantially horizontal elongated hole in the apron and has an actuating head which extends through the elongated hole to the end face of the punch.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung wird der Abstand zwischen der Schürze und einem die Lochstempel stirnseitig verdeckenden Querbalken über den gesamten Schwenkbereich des Druckhebels mindestens fingerbreit gewählt. Dadurch ist sichergestellt, daß auch in diesem Bereich ein versehentliches Einklemmen von Handteilen vermieden wird.According to a further preferred embodiment of the invention, the distance between the apron and a cross bar covering the punch on the end face is selected at least finger width over the entire swivel range of the pressure lever. This ensures that accidental pinching of hand parts is avoided in this area as well.

Der in Fig. 1 und 2 gezeigte Blechlocher besteht im wesentlichen aus einem Unterteil 10, einem mit dem Unterteil starr verbundenen Lagerteil 12 und einem an den Lagerböcken 14 des Lagerteils 12 um eine Achse 16 schwenkbar gelagerten Druckhebel 18. In dem Lagerteil 12 sind außerdem von je einer Schraubenfeder 20 umschlossene Lochstempel 22 geführt, die beim Niederdrücken des Druckhebels 18 unter Durchdringen des Einschubschlitzes 24 und einer Matrizenöffnung 26 im Unterteil 10 entgegen der Rückstellkraft der Federn 20 nach unten verschoben werden. Beim anschließenden Loslassen wird der Druckhebel unter der Einwirkung der Federn 20 in seine Ausgangslage selbsttätig zurückgeschwenkt.The sheet metal punch shown in FIGS. 1 and 2 essentially consists of a
Der Druckhebel 18 weist zwei seitlich nach unten gebogene Lagerlappen 28 auf, die die Lagerböcke 14 außenseitig überlappen. Weiter ist der Druckhebel 18 mit einer stirnseitig nach unten gebogenen, die beiden Lagerlappen 28 miteinander verbindenden Anschlagschürze 30 versehen. Die Schürze 30 weist in der Nähe ihrer Seitenränder und im Bereich ihrer Unterkante 32 eine nach hinten weisende lappenartige Abbiegung 34 auf, die zusammen mit dem benachbarten Lagerlappen 28 einen nach unten randoffenen und nach oben durch eine Stanzkante 36 in der Schürze geschlossenen Spalt 38 begrenzt. In diesen Spalt greift ein dünnwandiger Ausleger 40 des Lagerbocks 14 ein, der eine als Anschlag für die an der Schürze 30 angeordnete Querkante 36 dienende Stufe 42 aufweist. Grundsätzlich besteht auch die Möglichkeit, daß anstelle der Stufe 42 ein die Schürze 30 untergreifender Kantenteil des Auslegers 40 als Anschlag für den Druckhebel dient. Da die Weite des Spaltes 38 kleiner als 4 mm ausgebildet werden kann, besteht keine Gefahr, daß ein Finger zwischen die Anschlagkanten eingeklemmt wird. Wichtig ist nur, daß die Abbiegung 34 so lang ist, daß der Ausleger 40 auch bei niedergedrücktem Druckhebel 18 noch in den Spalt 38 eingreift.The
Die Lochstempelführungen im Lagerteil 12 sind stirnseitig durch einen Querbalken 43 verdeckt. Um auch in diesem Bereich ein Einklemmen von Handteilen zu vermeiden, weisen die Schürze 30 und der Querbalken 43 in allen Schwenklagen des Druckhebels 18 einen mindestens fingerbreiten Abstand voneinander auf.The punching guides in the
Bei dem in den Fig. 3 und 4 gezeigten Gußlocher sind das Unterteil 10 und die Lagerböcke 14 unter Freilassung des Einschubschlitzes 24 einstückig miteinander verbunden. Am Druckhebel 18 sind ebenfalls seitlich nach unten gebogene Lagerlappen 28 sowie eine die Lagerlappen stirnseitig miteinander verbindende, nach unten gebogene Schürze 30 vorgesehen. An den Lagerböcken 14 sind stirnseitig nach oben weisende Ausleger 50 angeordnet, die mit ihrer als Anschlagkante dienenden Oberkante 52 unter die Schürze 30 greifen. Auf der Innenseite der Schürze 30 stehen im Abstand von der Unterkante 32 Anschlagnocken 54 über, mit denen der Druckhebel 18 beim Zurückschwenken unter der Einwirkung der Federkraft gegen die Oberkanten 52 der Ausleger 50 anschlägt. Die Ausleger 50 weisen in ihrem unter die Schürze 30 greifenden Teil eine zur Schwenkachse 16 koaxiale teilzylindrische Krümmung auf, während die Schürze 30 auf ihrer den Auslegern 50 zugewandten Seite entsprechend schalenförmig ausgebildet ist. Dadurch kann der beim Niederdrücken des Druckhebels 18 zwischen der Schürze 30 und den Auslegern 50 vorhandene Spalt auf konstanter Weite von kleiner als 4 mm gehalten und damit die Einklemmgefahr vermieden werden.In the cast hole punch shown in FIGS. 3 and 4, the
Die beschriebene Anordnung der Anschläge des Gußlochers nach Fig. 3 und 4 eignet sich außerdem zur Unterbringung eines verstellbaren Anschlagschiebers 56 im Bereich zwischen der Schürzenunterkante 32 und einem der Anschlagnocken 54. Ein solcher Anschlagschieber 56, der in einem horizontalen Langloch 58 der Schürze 30 verschiebbar angeordnet ist, dient als Niederhalter für den Druckhebel 18, der beispielsweise für Transport- oder Lagerzwecke in Eingriff mit der benachbarten Ausleger-Oberkante 52 gebracht werden kann. Um den Lochvorgang nicht zu behindern, sollte der Anschlagschieber 56 zumindest in der aus dem Schwenkweg des Auslegers 50 ausgerückten Endstellung am Druckhebel 18 vorzugsweise in einer Rastverbindung arretierbar sein.The described arrangement of the stops of the cast hole punch according to FIGS. 3 and 4 is also suitable for accommodating an
