Abstract

The drawing head, having a catch and brake device (3) for fixing the drawing angle (1) in relation to a support plate (2), is equipped with preferably two sliding feet (8, 8') which are moulded onto spring arms and raise the drawing head from the drawing support. <IMAGE>

Description

Die Erfindung betrifft einen Zeichenkopf, der mit einer Rast- und einer Bremsvorrichtung zum Feststellen des Zei­chenwinkels gegenüber einer Tragplatte versehen ist, und bei dem die Rastvorrichtung sowohl ein stufenweises - in vorzugsweise 15° Schritten - Feststellen wie auch ein stufenloses Feststellen des Zeichenwinkels gegenüber der Tragplatte ermöglicht. Eine Bremseinrichtung fixiert dann den eingestellten Winkel, wenn dieser ungleich 15° oder eines Vielfachen hiervon ist.The invention relates to a drawing head, which is provided with a locking and a braking device for determining the drawing angle relative to a support plate, and in which the locking device both a step-wise - in preferably 15 ° steps - as well as a continuous determination of the drawing angle relative to the support plate enables. A braking device then fixes the set angle if it is not equal to 15 ° or a multiple thereof.

Derartige Zeichenköpfe sind beispielsweise aus der DE-PS 36 14 887 bekannt. Der in dieser Patentschrift beschrie­bene Zeichenkopf ist nicht nur mit den o.g. Merkmalen ausgestatten, sondern der Führungskörper dieses Zeichen­kopfes weist neben einer Bremsvorrichtung auch eine Führungsleiste, eine Einstellmarke für dessen Positionie­rung auf einer Führungsschiene, eine weitere Einstellmarke für die Winkelpositionierung des Zeichenwinkels auf.Such drawing heads are known for example from DE-PS 36 14 887. The drawing head described in this patent specification is not only compatible with the above. Features, but the guide body of this drawing head has in addition to a braking device also a guide bar, a setting mark for its positioning on a guide rail, a further setting mark for the angular positioning of the drawing angle.

Der Führungskörper ist einstückig mit Lagerkopf, Einstell­marke und Führungsleiste ausgebildet und kann durch eine Klemmtaste auf der Führungsschiene eines Zeichenlineales fixiert werden.
In gleicher Weise sind Zeichenköpfe bekannt, in deren Führungskörper - besser Tragplatte genannt - statt der Führungsleiste eine auf eine entsprechende Rippe der Zei­chenschiene aufsteckbare Nut vorgesehen ist. Auch bei die­ser Lösung sind Fixierelemente bekannt.The guide body is made in one piece with a bearing head, setting mark and guide bar and can be fixed on the guide rail of a drawing ruler using a clamping button.
In the same way, drawing heads are known, in the guide body - better called the support plate - instead of the guide bar, a groove which can be plugged onto a corresponding rib of the drawing rail is provided. Fixing elements are also known in this solution.

Nachteilig an diesen bekannten Lösungen ist, daß diese ausschließlich auf Zeichenplatten oder Zeichenanlagen gleicher Hersteller eingesetzt werden können, da die Führungselemente des Zeichenkopfes direkt in die Gegen­stücke der Zeichenschiene eingreifen.A disadvantage of these known solutions is that they are used exclusively on drawing boards or drawing systems same manufacturer can be used, since the guide elements of the drawing head directly engage in the counterparts of the drawing rail.

Aufgabe der Erfindung ist es daher, einen Zeichenkopf zu schaffen, der bei preiswerter Gestaltung und einfacher Handhabung universell auf allen Zeichenanlagen eingesetzt werden kann.The object of the invention is therefore to provide a drawing head which can be used universally on all drawing systems with inexpensive design and simple handling.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 in besonders vorteilhafter Weise gelöst.This object is achieved in a particularly advantageous manner by the features of claim 1.

Eine bevorzugte Ausführungsform dieser Erfindung wird in den weiteren Ansprüchen dieser Anmeldung beschrieben.A preferred embodiment of this invention is described in the further claims of this application.

Anhand der ein Ausführungsbeispiel zeigenden Figuren wird die Erfindung näher erläutert. Hierbei zeigt:

  • Figur 1 - eine Draufsicht auf einen Zeichen­kopf, wobei die Lineale abgeschnit­ten wurden,
  • Figur 2 - eine Vorderansicht in entlasteter Position,
  • Figur 3 - eine Vorderansicht in belasteter Position.
The invention is explained in more detail with reference to the figures showing an exemplary embodiment. Here shows:
  • FIG. 1 shows a plan view of a drawing head, the rulers being cut off,
  • FIG. 2 - a front view in the unloaded position,
  • Figure 3 - a front view in the loaded position.

Der in Figur 1 mit abgeschnitten Linealen dargestellte erfindungsgemäße Zeichenkopf ist mit einer Drucktaste (4) zur Betätigung der Rasteinrichtung, die zusammen mit dem Drehgriff (14) und dem Zeichenwinkel (1) fest verbunden aber gegenüber der Tragplatte (2) verdrehbar ist. Soll ein bestimmter Winkel eingestellt werden, hält man mit der einen Hand die Tragplatte (2) fest und verdreht mittels Drucktaste (4) und Drehgriff (14) den Zeichenwinkel (1) so lange, bis der gewünschte Winkel an der Einstellmarke (10) abgelesen werden kann. Dieser Winkel kann dann mittels der Bremseinrichtung (3) fixiert werden. Wird beim Einstellen des gewünschten Winkels die Tragplatte (2) auf den Zeichenträger (9) gedrückt, so bekommen die Antirutschfüßchen (6,6′) Kontakt mit dem Zeichenträger, und ein Verrutschen der Tragplatte ist da­mit unmöglich.The drawing head according to the invention shown in FIG. 1 with cut-off rulers is connected to a push button (4) for actuating the latching device, which together with the turning handle (14) and the drawing angle (1) are firmly connected but is rotatable relative to the support plate (2). If a certain angle is to be set, hold the support plate (2) with one hand and turn the drawing angle (1) using the pushbutton (4) and rotary handle (14) until the desired angle can be read on the setting mark (10) can be. This angle can then be fixed by means of the braking device (3). If the support plate (2) is pressed onto the character carrier (9) when setting the desired angle, the anti-slip feet (6,6 ') get in contact with the character carrier, and slipping of the carrier plate is impossible.

Das nunmehr eingestellt Gerät kann auf seinen Gleitfüß­chen (8,8′) auf der Zeichenunterlage (9) leicht verscho­ben werden. Sollen nun mehrere parallele Linien gezeich­net werden, so kann der Zeichenkopf mit seiner Führungs­leiste (5) an der Zeichenkante eines Lineals geführt wer­den.The now discontinued device can be easily moved on its sliding feet (8.8 ') on the drawing pad (9). If several parallel lines are now to be drawn, the drawing head can be guided with its guide bar (5) on the drawing edge of a ruler.

An den Endbereichen der Tragplatte (2) sind auf deren dem Zeichenträger zugewandten Seite sog. Antirutschfüßchen (6,6′) angeordnet. Während des Verschiebevorganges haben die Antirutschfüßchen (6,6′) keinen Kontakt zum Zeichen­träger (9). Durch die Wirkung der in die Gleitfüßchen übergehenden Feder (7) wird die Tragplatte (2) vom Zei­chenträger abgehoben. Diese Feder (7) ist in einer ent­sprechenden Vertiefung der Tragplatte (2) untergebracht. Um der Feder (7) einen sicheren Halt zu geben, ist an der Tragplatte (2) ein zylinderförmiger Zapfen (11) vorgesehen, auf den die Feder (7) aufgesteckt wird.At the end regions of the support plate (2) so-called anti-slip feet (6,6 ') are arranged on the side facing the character carrier. During the displacement process, the anti-slip feet (6,6 ') have no contact with the character carrier (9). Due to the action of the spring (7) passing into the sliding feet, the support plate (2) is lifted off the character carrier. This spring (7) is housed in a corresponding recess in the support plate (2). In order to give the spring (7) a secure hold, a cylindrical pin (11) is provided on the support plate (2), onto which the spring (7) is attached.

Die Gleitfüßchen (8,8′) können, um ein besseres Gleiten zu gewährleisten, mit einem gleitfähigen Material be­schichtet werden. Hierfür dürfte besonders PTFE geeignet sein.
Selbstverständlich können Gleitfüßchen (8,8′) und Feder (7) aus einem Stück und somit aus demselben Material ge­fertigt sein.The sliding feet (8.8 ') can be coated with a lubricious material to ensure better sliding. PTFE should be particularly suitable for this.
Of course, sliding feet (8,8 ') and spring (7) can be made from one piece and thus from the same material.
