Definitions
- the invention relates to a stop bracket, consisting of a stop rail and a ruler fastened at one end and extending at right angles to it according to the first part of claim 1.
- a stop bracket is known from GB-A-519 637.
- the stop rail When working with this stop angle, the stop rail is placed on the end face of an edge of the workpiece.
- the stop bracket must be held in this position.
- the object of the invention is to design the stop angle so that it remains on the workpiece by itself.
- the support tongue consists of a swivel plate which is pivotally mounted on the stop rail about a swivel axis.
- the swivel axis is located at a point that is close to the ruler and near the inner longitudinal edge of the stop rail. In its rest position, the tongue lies within the contour of the stop rail, although it can also protrude from the front on its free narrow side.
- the opening width of the longitudinal slot is preferably determined by the wall thickness of the ruler, while the wall thickness of the support tongue has a small undersize compared to the wall thickness of the ruler, which is sufficient for easily moving the tongue out of the longitudinal slot.
- the advantage of the invention is that the support tongue rests on the workpiece and holds the stop angle in position. A slight overlap of the workpiece is sufficient to achieve this goal.
- the advantage of the longest possible contact tongue which is approximately equal to the length of the stop rail reduced by the ruler width, enables several straight lines to be provided at an angle to one another, e.g. form an angle of 15 °, 30 and / or 45 with the straight longitudinal edge of the support tongue, so that either one of the lines is made to coincide with the inner longitudinal edge of the stop rail forming the stop surface, so that the longitudinal edge of the support tongue for marking the under the selected angle lying line on the workpiece can be used. It goes without saying that the lines can also be replaced by marking lines and at smaller angular intervals in the manner of an angle meter.
- the stop bracket 10 consists of a ruler 12 and a stop rail 14 which are connected to one another at right angles.
- the stop rail 14 consists of two profile pieces 16, 18, each having a top wall 20 or 22, each of which has a flange 26 on the inner longitudinal edge 24 forming the stop surface, which flange forms a widened stop surface.
- the profile piece 22 On the opposite outer edge 28, the profile piece 22 has a longitudinal projection of a height approximately equal to the wall thickness of the ruler 12. From this projection, a longitudinal web 30 protrudes upwards, which engages in a longitudinal groove 32 in the other profile piece 16, so that a positive connection is created .
- the two profile pieces 16, 18 are glued to the mutual contact surfaces in the region of the longitudinal web 30 and the longitudinal groove 32 and to the adjacent surfaces of the projection, so that there is an approximately U-shaped cross section of the stop rail, with a flat, extending over the entire rail length central chamber.
- the ruler 12 is inserted into this chamber at one end of the stop rail 14 and connected by means of rivets 34, 36.
- a support tongue 38 is housed, the length of which is approximately equal to the length of the stop rail 14 reduced by the ruler width and the width of which is slightly less than the clear width of the flat receiving chamber, so that the rest tongue is in its rest position fully inside the stop rail is included if one disregards an end recess 40 of the stop rail provided on the free transverse edge, which recess represents a handle opening for moving out the support tongue 38.
- a pin 42 Adjacent to the ruler 12 and adjacent to the inner longitudinal edge 24, a pin 42 passes through the stop rail 14.
- the pin 42 forms a pivot pin for the support tongue 38.
- the wall thickness of the support tongue is slightly smaller than that of the ruler 12, so that the support tongue 38 easily through the longitudinal slot can emerge from the inner longitudinal edge 25 of the stop rail.
- the support tongue consists of an approximately rectangular plate with a straight-line marking edge 44 which, in the rest position, lies approximately parallel to the inner longitudinal edge 24 within the stop rail 14 and slightly within this longitudinal edge. Furthermore, there are at least one, but preferably on both cover surfaces of the support tongue 38 marking lines 46, 48, 50, which in the exemplary embodiment are 15 °, 30 °. 45 ° with the Form scribing edge 44. These marking lines 46, 48, 50 do not meet exactly at one point together with the marking edge 44, which would require that the support tongue could be pivoted about this geometric point, rather their respective position is defined in such a way that when the support tongue 38 is pivoted the respective angle, the associated marking line with the longitudinal edge 24 of the stop rail 14 comes to coincide.
- the rest tongue 38 is fully accommodated in the rest position within the contour of the stop rail and therefore does not interfere with the usual handling of the stop angle.
- a slight outward pivoting of the support tongue is sufficient to ensure that the tongue overlaps the workpiece or the work table, so that the stop angle can be released and maintains its position.
- the angular graduation on the support tongue 38 enables angular lines to be marked quickly.

Abstract
Description
Die Erfindung betrifft einen Anschlagwinkel, bestehend aus einer Anschlagschiene und einem an deren einem Ende befestigten und sich zu ihr rechtwinklig erstreckenden Lineal nach dem ersten Teil des Anspruchs 1. Ein derartiger Anschlagwinkel ist aus der GB-A-519 637 bekannt.The invention relates to a stop bracket, consisting of a stop rail and a ruler fastened at one end and extending at right angles to it according to the first part of claim 1. Such a stop bracket is known from GB-A-519 637.
Beim Arbeiten mit diesem Anschlagwinkel wird die Anschlagschiene stirnseitig an eine Kante des Werkstückes angelegt. Der Anschlagwinkel muß in dieser Stellung festgehalten werden.When working with this stop angle, the stop rail is placed on the end face of an edge of the workpiece. The stop bracket must be held in this position.
Aufgabe der Erfindung ist es, den Anschlagwinkel so auszubilden, daß er von selbst auf dem Werkstück liegen bleibt.The object of the invention is to design the stop angle so that it remains on the workpiece by itself.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the features of claim 1.
Die Auflagezunge besteht aus einer Schwenkplatte, die um eine Schwenkachse an der Anschlagschiene schwenkbar gelagert ist. Die Schwenkachse befindet sich an einer Stelle, die nahe dem Lineal und nahe dem inneren Längsrand der Anschlagschiene liegt. Die Zunge liegt dabei in ihrer Ruhestellung innerhalb der Kontur der Anschlagschiene, obwohl sie auch an deren freier Schmalseite stirnseitig überstehen kann. Die Öffnungsweite des Längsschlitzes wird dabei vorzugsweise durch die Wanddicke des Lineals bestimmt, während die Wanddicke der Auflagezunge ein gegenüber der Wanddicke des Lineals geringes Untermaß hat, das zum leichten Herausbewegen der Zunge aus dem Längsschlitz ausreicht.The support tongue consists of a swivel plate which is pivotally mounted on the stop rail about a swivel axis. The swivel axis is located at a point that is close to the ruler and near the inner longitudinal edge of the stop rail. In its rest position, the tongue lies within the contour of the stop rail, although it can also protrude from the front on its free narrow side. The opening width of the longitudinal slot is preferably determined by the wall thickness of the ruler, while the wall thickness of the support tongue has a small undersize compared to the wall thickness of the ruler, which is sufficient for easily moving the tongue out of the longitudinal slot.
Der Vorteil der Erfindung besteht darin, daß die Auflagezunge auf dem Werkstück aufliegt und den Anschlagwinkel in Position hält. Es genügt schon eine geringfügige Überlappung des Werkstückes um dieses Ziel zu erreichen.The advantage of the invention is that the support tongue rests on the workpiece and holds the stop angle in position. A slight overlap of the workpiece is sufficient to achieve this goal.
Der Vorteil einer möglichst langen Auflagezunge, die etwa gleich der um die Linealbreite verringerten Länge der Anschlagschiene ist, ermöglicht auf der Auflagezunge mehrere winklig zueinanderliegende gerade Linien vorzusehen, die z.B. mit der geraden Längkante der Auflagezunge einen Winkel von 15 °, 30 und/oder 45 bilden, so daß wahlweise eine der Linien mit dem inneren die Anschlagfläche bildenden Längsrand der Anschlagschiene zur Deckung gebracht wird, so daß die Längskante der Auflagezunge zum Anreißen der unter dem gewählten Winkel liegenden Linie auf dem Werkstück benutzt werden kann. Dabei versteht sich, daß die Linien auch durch Markierungsstriche und auch in geringeren Winkelabständen nach Art eines Winkelmessers ersetzt werden können.The advantage of the longest possible contact tongue, which is approximately equal to the length of the stop rail reduced by the ruler width, enables several straight lines to be provided at an angle to one another, e.g. form an angle of 15 °, 30 and / or 45 with the straight longitudinal edge of the support tongue, so that either one of the lines is made to coincide with the inner longitudinal edge of the stop rail forming the stop surface, so that the longitudinal edge of the support tongue for marking the under the selected angle lying line on the workpiece can be used. It goes without saying that the lines can also be replaced by marking lines and at smaller angular intervals in the manner of an angle meter.

Der Anschlagwinkel 10 besteht aus einem Lineal 12 und einer Anschlagschiene 14, die miteinander rechtwinklig verbunden sind. Die Anschlagschiene 14 besteht aus zwei Profilstücken 16, 18, die je eine Deckwand 20 bzw. 22 aufweisen, welche am inneren, die Anschlagfläche bildenden Längsrand 24 jeweils einen Flansch 26 aufweisen, der eine verbreiterte Anschlagfläche bildet. Am gegenüberliegenden Außenrand 28 hat das Profilstück 22 einen Längsvorsprung von einer Höhe etwa gleich der Wanddicke des Lineals 12. Von diesem Vorsprung ragt weiterhin ein Längssteg 30 nach oben, der in eine Längsnut 32 im anderen Profilstück 16 eingreift, so daß eine formschlüssige Verbindung geschaffen wird. Die beiden Profilstücke 16, 18 sind an den gegenseitigen Berührungsflächen im Bereich des Längssteges 30 und der Längsnut 32 und an den benachbarten Flächen des Vorsprunges verklebt, sodaß sich ein etwa U-förmiger Querschnitt der Anschlagschiene ergibt, mit einer flachen, über die gesamte Schienenlänge reichenden zentralen Kammer.The
In diese Kammer ist an einem Ende der Anschlagschiene 14 das Lineal 12 eingesteckt und mittels Nieten 34, 36 verbunden.The
In der flachen Kammer ist eine Auflagezunge 38 untergebracht, deren Länge etwa gleich der um die Linealbreite verringerten Länge der Anschlagschiene 14 ist und deren Breite geringfügig kleiner als die lichte Breite der flachen Aufnahmekammer ist, so daß die Auflagezunge in ihrer Ruhestellung voll im Innern der Anschlagschiene aufgenommen ist, wenn man von einer am freien Querrand vorgesehenen stirnseitigen Aussparung 40 der Anschlagschiene absieht, die eine Grifföffnung zum Herausbewegen der Auflagezunge 38 darstellt.In the flat chamber a
Benachbart des Lineals 12 und benachbart des inneren Längsrandes 24 durchsetzt ein Stift 42 die Anschlagschiene 14. Der Stift 42 bildet einen Schwenkzapfen für die Auflagezunge 38. Die Wandstärke der Auflagezunge ist geringfügig kleiner als diejenige des Lineals 12, sodaß die Auflagezunge 38 leicht durch den Längsschlitz am inneren Längsrand 25 der Anschlagschiene austreten kann.Adjacent to the
Die Auflagezunge besteht aus einer etwa rechteckigen Platte mit einer geradlinigen Anreißkante 44, die in der Ruhestellung innerhalb der Anschlagschiene 14 etwa parallel zum inneren Längsrand 24 und geringfügig innerhalb dieses Längsrandes liegt. Weiterhin befinden sich mindestens auf einer, vorzugsweise aber auf beiden Deckflächen der Auflagezunge 38 Markierungslinien 46, 48, 50, die im Ausführungsbeispiel 15°, 30°. 45° mit der Anreißkante 44 bilden. Diese Markierungslinien 46, 48, 50 treffen sich nicht exakt in einem Punkt zusammen mit der Anreißkante 44, was erforderlich machen würde, daß die Auflagezunge um diesen geometrischen Punkt schwenkbar wäre, vielmehr ist ihre jeweilige Lage so definiert, daß bei Verschwenkung der Auflagezunge 38 um den jeweiligen Winkel die zugehörige Markierungslinie mit dem Längsrand 24 der Anschlagschiene 14 zur Deckung kommt.The support tongue consists of an approximately rectangular plate with a straight-line marking edge 44 which, in the rest position, lies approximately parallel to the inner
Die Auflagezunge 38 ist in ihrer Ruhestellung voll innerhalb der Kontur der Anschlagschiene aufgenommen und stört also nicht die übliche Handhabung der Anschlagwinkels. Ein geringfügiges Auswärtsschwenken der Auflagezunge genügt schon, um zu erreichen, daß die Zunge das Werkstück oder den Arbeitstisch überlappt, sodaß der Anschlagwinkel losgelassen werden kann und seine Position beibehält. Die Winkeleintreilung auf der Auflagezunge 38 ermöglicht das schnelle Anreißen von Winkellinien.The
