Description

Die Erfindung bezieht sich auf einen Schnellverstellzirkel mit einer die Zirkelschenkel in darin gelagerten Gewindehülsen durchsetzenden mitlaufenden Gewinde-Verstellspindel mit einem mittig angeordneten, drehfest mit der Verstellspindel verbundenen Verstellrad, wobei die Verstellspindel mittels die Zirkelschenkel zumindest teilweise durchsetzender Feststellschrauben in den Gewindehülsen blockierbar ist.The invention relates to a Schnellverstellzirkel with one of the compass legs in therein threaded sleeves passing through running threaded adjusting spindle with a centrally arranged, non-rotatable with the adjusting spindle connected adjusting wheel, wherein the adjusting spindle by means of the compass legs at least partially enforcing locking screws in the threaded sleeves is blockable.

Ein herkömmlicher, nicht schnell verstellbarer Zirkel zeichnet sich dadurch aus, dass zwischen der Verstellspindel und dem in der Gewindehülse angebrachten Muttergewinde bei Druck gegen die Schenkel eine Selbsthemmung auftritt. Das bedeutet, dass eine Verstellung des Zirkels nur über eine Feinverstellung mit Hilfe des Verstellrades möglich ist. Diese Verstellung ist bei größeren Verstellstrecken jedoch entsprechend aufwändig.A conventional, not quickly adjustable compass is characterized by that between the adjusting spindle and the mounted in the threaded sleeve Female thread when pressure against the thighs a self-locking occurs. The means that an adjustment of the compass using only a fine adjustment the adjusting wheel is possible. This adjustment is at larger Verstellstrecken however, correspondingly expensive.

In der deutschen Auslegeschrift DE 1 761 101 wird nun vorgeschlagen, die Zahl der Gewindegänge und ihre Steigung so zu bemessen, dass diese Selbsthemmung nicht mehr besteht. Die Spindel läuft also bei Druck auf die Schenkel mit und erlaubt so eine Schnellverstellung sowie über das Verstellrad eine Feinabstimmung. Eine solche Anordnung kann aber leicht ungewollt verstellt werden, da bereits kleine Kräfte zum Mitlaufen der Spindel führen.In German Auslegeschrift DE 1 761 101 it is now proposed to use the number the threads and their pitch so that this self-locking no longer exists. The spindle thus runs with pressure on the legs and thus allows a quick adjustment as well as a fine tuning via the adjusting wheel. Such an arrangement can easily be adjusted unintentionally, since already lead small forces to run along the spindle.

Zur Herstellung solcher Schnellverstellzirkel ist beispielsweise bereits vorgeschlagen worden, die Gewindehülsen in einer durch die Achse der Verstellspindel gehenden Ebene zu teilen, wobei diese Teile durch eine Feststellschraube indirekt unter Zwischenordnung von Schwenkplatten gegeneinander verspannbar sind. Dies bedingt aber ein außerordentlich festes Anziehen der Verstellschraube und führt in vielen Fällen zwar zu einer Bremswirkung, aber nicht zu einer exakten Feststellung.For the preparation of such Schnellverstellzirkel example, has already been proposed been, the threaded sleeves in a going through the axis of the adjusting spindle To divide plane, these parts indirectly by a locking screw can be braced against each other with the interposition of pivot plates. However, this requires an extremely tight tightening the adjustment and Although in many cases leads to a braking effect, but not to a precise Finding.

Darüber hinaus ist aber auch bereits eine Anordnung bekannt geworden, bei der aus dem Zirkelschenkel herausragende Enden der Gewindehülsen geschlitzt und mit konischen Außenflächen versehen sind, auf die entsprechende Gegenkonushülsen verschiebbar sind, die in der einen Stellung den Gewindehülsenkonus freigeben, sodass ein freies Verdrehen der Verstellspindel möglich ist und in der anderen Stellung den geschlitzten Gewindehülsenkonus zusammendrücken um auf diese Weise die Verstellspindel zu blockieren. Diese Lösung ist nicht nur sehr aufwändig, sondern hat, wie die bereits angesprochene Konstruktion, den Nachteil, dass ein völliges spielfreies Blockieren der Verstellspindel und damit der gewünschten Stellung des Schnellverstellzirkels nicht erzielbar ist.In addition, however, an arrangement has already become known in the slotted out of the compass legs protruding ends of the threaded sleeves and are provided with conical outer surfaces, on the corresponding Gegenkonushülsen are displaceable, which release the threaded sleeve cone in one position, so that a free rotation of the adjusting spindle is possible and in the other Position the slotted threaded sleeve cone together to press on this way to block the adjusting spindle. This solution is not only very consuming, but has, like the construction already mentioned, the disadvantage that a complete backlash blocking the adjusting spindle and thus the desired Position of Schnellverstellzirkels is not achievable.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Schnellverstellzirkel der eingangs genannten Art so auszugestalten, dass bei einfachem Aufbau ein völliges spielfreies Blockieren der Verstellspindel in jeder beliebigen Schwenkstellung des Schnellverstellzirkels möglich ist.The invention is therefore based on the object, a Schnellverstellzirkel the the type mentioned above in such a way that with a simple structure a complete play-free blocking of the adjusting spindle in any pivot position the quick-release compass is possible.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass durch die Feststellschraube die Verstellspindel mit ihrem Gewinde direkt an ein Blockierglied anpressbar ist.To solve this problem, the invention provides that through the Locking screw, the adjusting spindle with its thread directly to a blocking member can be pressed.

Eine erste Ausführungsform dieser erfindungsgemäßen Lösung, bei der nicht die Gewindehülse zum Feststellen der Verstellspindel verspannt wird, sieht zu diesem Zweck vor, dass die Gewindehülse ein in einer senkrecht zur Achse der Gewindestange durchgehende Ausnehmung des Zirkelschenkels verschiebbar gelagerter Bolzen mit Quergewindebohrungen für die Gewindestange ist, der durch eine auf einen endseitigen Außengewindeabschnitt aufschraubbare Gewindemutter unter Verspannen der Gewindestange an der Innenwand des von ihr durchsetzten Querdurchbruchs des Zirkelschenkels verstellbar ist.A first embodiment of this solution according to the invention, in which not the Threaded sleeve is tightened for detecting the adjusting spindle, looks at this Purpose before that the threaded sleeve in a direction perpendicular to the axis of the threaded rod continuous recess of the compass leg slidably mounted Bolt with cross threaded holes for the threaded rod is by a on an end male threaded portion screwed threaded nut below Bracing the threaded rod on the inner wall of the enforced by her Transverse breakthrough of the compass leg is adjustable.

Bei dieser Lösung wird also durch die Feststellschraube der Bolzen mit der Verstellspindel quer zu der Längsachse seitlich verschoben, sodass sich die Verstellspindel mit ihrem Außengewinde unmittelbar an die Innenwand des Querdurchbruchs des Zirkelschenkels anlegt und auf diese Art und Weise blockiert wird. Bei dieser Ausführungsform bildet also die Innenwand des Querdurchbruchs des Zirkelschenkels das Blockierglied für die Verstellspindel. In this solution, so by the locking screw of the bolt with the adjusting spindle moved laterally to the longitudinal axis, so that the adjusting spindle with its external thread directly to the inner wall of the transverse breakthrough of the circular leg and blocked in this way. at This embodiment thus forms the inner wall of the transverse breakthrough of the compass leg the blocking element for the adjusting spindle.

Gemäß einer zweiten Ausführungsform der erfindungsgemäßen Lösung mit einem gesonderten Blockierglied ist vorgesehen, dass die Feststellschraube einen die Gewindehülse quer zur Gewindebohrung für die Verstellspindel durchsetzenden Blockierstift in das Gewinde der Verstellspindel drückt. Diese Lösung, bei der der Blockierstift bevorzugt aus Kunststoff ausgebildet sein kann, sodass eine Beschädigung des Gewindes der Verstellspindel nicht stattfinden kann, führt in ganz besonders einfacher Weise zu einer exakten spielfreien Blockierung der Verstellspindel.According to a second embodiment of the solution according to the invention with a Separate blocking member is provided that the locking screw a the Pass threaded sleeve across the threaded hole for the adjusting spindle Locking pin presses into the thread of the adjusting spindle. This solution, in which the Blocking pin may preferably be formed of plastic, so that damage the thread of the adjusting spindle can not take place leads in particular easy way to an exact play-free blocking of the adjustment.

In Weiterbildung dieses zweiten Ausführungsbeispiels der Erfindung kann entweder vorgesehen sein, dass der Blockierstift der Gewindestift der Feststellschraube ist, die in eine Quergewindebohrung der Gewindehülse oder des Zirkelschenkels einschraubbar ist oder aber dass die Gewindehülse ein in einer senkrecht zur Achse der Gewindestange durchgehende Ausnehmung des Zirkelschenkels gelagerter Bolzen mit hohlem Schaft ist, der auf einer Seite sich mit einem Kopf am Zirkelschenkel abstützt, auf dessen herausstehenden anderen, mit einem Außengewinde versehenen Ende, eine Hutmutter unter Verschiebung des Blockierstifts in der Innenbohrung des Schaftes aufschraubbar ist.In development of this second embodiment of the invention can either be provided that the locking pin of the set screw of the locking screw is that in a cross threaded hole of the threaded sleeve or the circular leg is screwed or that the threaded sleeve in a perpendicular to the Axle of the threaded rod through recess of the compass leg mounted Bolt with hollow shaft is on one side with a head on Gimbal legs supported, on the other protruding, with an external thread provided end, a cap nut under displacement of the locking pin in the inner bore of the shaft can be screwed.

Die Ausbildung ist bei dieser zweiten Variante ähnlich der Lösung mit am Zirkelschenkel verklemmter Verstellspindel, wobei allerdings hier die Verstellspindel nicht durch Verklemmen an den Zirkelschenkel blockiert wird sondern durch den im hohlen Bolzen der Gewindehülse über die Feststell-Hutmutter verschiebbaren Blockierstift.The training is similar in this second variant of the solution with the compass legs jammed adjusting spindle, although here the adjusting spindle is not blocked by jamming to the compass legs but by the slidable in the hollow bolt of the threaded sleeve over the locking cap nut Blocking pin.

Fig. 2 to 5
enlarged partially cutaway partial side views of the compass leg at the height of the threaded adjusting spindle in the direction of arrow P in Fig. 1st

In Fig. 1 erkennt man einen Schnellverstellzirkel mit zwei an einem Kopfteil 1 schwenkbar gelagerten Zirkelschenkeln 2 und 3, die von einer Gewindeverstellspindel 4 mit Verstellrad 5 durchsetzt werden, wobei die Gewindeverstellspindel in unterschiedlicher Weise ausbildbare, in Fig. 2 gezeigte Gewindehülsen 6 durchsetzt, die in quer zur Achse der Gewindeverstellspindel verlaufenden Durchbrechungen der Zirkelschenkel 2, 3 gelagert sind. Ein in Fig. 2 gezeigter großer Durchbruch 7 ermöglicht jeweils das starke Querverstellen zwischen Zirkelschenkel und Gewindeverstellspindel.In Fig. 1 can be seen a Schnellverstellzirkel with two on a headboard. 1 pivotally mounted compass legs 2 and 3, by a threaded adjusting spindle 4 are traversed with adjusting 5, wherein the threaded adjusting spindle in enforced in different ways, shown in Fig. 2 threaded sleeves 6 interspersed, the openings extending transversely to the axis of the threaded adjusting spindle the compass legs 2, 3 are stored. A shown in Fig. 2 large Breakthrough 7 allows each strong transverse displacement between compass legs and threaded adjusting spindle.

Im gezeigten Ausführungsbeispiel sind an jedem der Zirkelschenkel 2, 3 Feststelleinrichtungen angeordnet, obgleich es für die Funktionsweise natürlich ausreichend wäre, wenn nur einer der Schenkel mit einer solchen Feststelleinrichtung versehen wäre. Die einfachste Form der Blockierung der Gewindeverstellspindel und damit der Feststellung des Schnellverstellzirkels in einer gewünschten Schwenkposition ist in Fig. 2 dargestellt. Die Gewindehülse 6 bildet dort den in der senkrecht zur Achse der Verstellspindel durchgehenden Ausnehmung 8 gelagerten Bolzen mit einer Gewindebohrung 9 für die Verstellspindel, in die eine Quergewindebohrung 10 einmündet, in die eine Feststellschraube 11 einschraubbar ist. Der Schaft 12 dieser Feststellschraube greift beim Einschrauben direkt am Außengewinde der Verstellspindel 4 an und blockiert diese und damit den Zirkel in der gewünschten Position.In the illustrated embodiment, each of the compass legs 2, 3 locking devices Although it is sufficient for the operation of course would be if only one of the legs with such a locking device would be provided. The simplest form of blocking the threaded adjusting spindle and thus the determination of Schnellverstellzirkels in a desired Pivoting position is shown in Fig. 2. The threaded sleeve 6 forms there in the mounted perpendicular to the axis of the adjusting spindle through recess 8 Bolt with a threaded hole 9 for the adjusting spindle into which a cross threaded hole 10 opens, in which a locking screw 11 is screwed. The shaft 12 of this locking screw engages when screwing directly to the external thread the adjusting 4 and blocks them and thus the compass in the desired position.

Die Fig. 3 zeigt eine Abwandlung die sich von der nach Fig. 2 nur dadurch unterscheidet, dass es sich bei der Feststellschraube 11' um eine Kunststoffschraube handelt, was den Vorteil hat, dass bei der Blockierung der meist metallischen Gewindeverstellspindel 4 deren Außengewinde nicht durch die Feststellschraube verdrückt wird, wie dies bei der metallischen Feststellschraube 11 nach Fig. 2 der Fall sein könnte. 3 shows a modification which differs from that of FIG. 2 only by that it is at the locking screw 11 'to a plastic screw acts, which has the advantage that when blocking the most metallic threaded spindle 4 whose external thread is not through the locking screw is pressed, as in the metallic locking screw 11 of FIG. 2 of Case could be.

Bei der Anordnung nach Fig. 4 ist der die Gewindehülse 6' für die Gewindeverstellspindel bildende Bolzen in gleicher Weise im Zirkelschenkel 2 (und gegebenenfalls auch 3) gelagert, wobei der Bolzen auf der rechten Seite mit einem Außengewinde 13 versehen ist, auf die eine Hutmutter 14 mit Innengewinde aufschraubbar ist, sobald diese Hutmutter 14 an der Seite 15 des Zirkelschenkels anliegt, zieht sie beim Weiterdrehen den Bolzen nach rechts und drückt damit die Gewindeverstellspindel 4 an die Innenseite 16 des Durchbruchs 7 an, sodass wiederum eine Blockierung der Verstellspindel 4 erreicht wird.In the arrangement of FIG. 4 is the threaded sleeve 6 'for the threaded adjusting spindle forming bolts in the same way in the compass leg 2 (and optionally Also 3) stored, with the bolt on the right side with an external thread 13 is provided, on which a cap nut 14 with internal thread screwed is, as soon as this cap nut 14 on the side 15 of the compass leg As it continues to rotate, it pulls the bolt to the right and thus presses the bolt Thread adjusting spindle 4 to the inside 16 of the opening 7, so in turn a blockage of the adjusting spindle 4 is achieved.

Beim Ausführungsbeispiel nach Fig. 5, bei dem der ein Durchdrücken verhindernde Bund 17 auf der linken Seite auch weggelassen werden könnte, ist der die Gewindehülse 6" bildende Bolzen wiederum mit einem Außengewinde 13 für eine Hutmutter 14 versehen, doch dient diese hierbei zum Verschieben eines Stiftes 18 in einer Innenbohrung 19, die bis zur Quergewindebohrung 9 reicht. Beim Aufschrauben der Hutmutter 14 auf das Außengewinde 13 des Bolzens wird der Stift 18, vorzugsweise ein Kunststoffstift, wegen der Schonung des Außengewindes der Verstellspindel 4 nach links an die Verstellspindel 4 angedrückt und blockiert diese in der jeweiligen Stellung.In the embodiment of Fig. 5, in which the press-through preventing Covenant 17 on the left side could be omitted, which is the threaded sleeve 6 "forming bolts turn with an external thread 13 for a Cap nut 14 provided, but this serves to move a pin 18th in an inner bore 19 which extends to the transverse threaded hole 9. When screwing the cap nut 14 on the external thread 13 of the bolt is the pin 18, preferably a plastic pin, because of the protection of the external thread the adjusting spindle 4 is pressed to the left to the adjusting spindle 4 and blocked these in the respective position.
