Description

aus zwei U-förniigen Schienen besteht, von denen die eine die ihr zugekehrten Schenkel der anderen aufnimmt und in ihrem Jochteil die Löcher aufweist, weil dadurch die Hohlschiene aus zwei U-Profilschienen zusammengesetzt werden kann.consists of two U-shaped rails, of which the one of the legs facing it receives the other and has the holes in its yoke part, because this allows the hollow rail to be assembled from two U-profile rails.

Im folgenden ist die Erfindung an Hand eines in der Zeichnung dargestellten Ausführungsbeispiels im einzelnen e läutert. Es zeigtIn the following the invention is based on an embodiment shown in the drawing in individual e purifies. It shows

Fig. 2 einen Querschnitt nach der Linie H-II der Fig. 1.Fig. 2 is a cross section along the line H-II of Fig. 1.

Fig. 3 einen unvollständig dargestellten Schnitt nach der Linie III-III der F i g. 2.3 shows an incomplete section according to the line III-III of FIG. 2.

An den beiden Enden einer U-Profilschiene 1 sind je ein Holm 2 bzw. 3 angelenkt, wobei die Gelenkachse senkrecht zur Längsachse der Profilschiene 1 und senkrecht zu deren Schenkel steht. Die Holme 2 und 3 sind daher in einer durch die Längsachse der U-P'rofilschine 1 gehenden Ebene schwenkbar. Die Schenkel der U-Profhschiene 1 weisen von den Holmen 2 und 3 weg, in der Gebrauchslage, in der die beiden Holme in vertikalstehende Rohre eines nicht dargestellten Arbeitsbockes eingeseü* sind, also nach oben.At the two ends of a U-profile rail 1 a spar 2 and 3 are hinged, the hinge axis perpendicular to the longitudinal axis of the profile rail 1 and perpendicular to the legs. the Spars 2 and 3 can therefore be pivoted in a plane passing through the longitudinal axis of the U-profile rail 1. The legs of the U-Profhschiene 1 point away from the bars 2 and 3, in the position of use, in the two spars in vertical tubes of a work trestle, not shown * are, so to the top.

Wie Fig.2 zeigt, ist auf die untere U-Profilschiene 1 eine obere U-Profilschiene 4 aufgesetzt, deren nach unten weisende Schenkel die nach oben weisenden Schenkel der unteren Profilschiene 1 aufnehmen. Die beiden lösbar mittels Schrauben S verbundenen U-Profilschienen 1 und 4 bilden eine Traverse. Der obenliegende Jochteil der oberen U-Profilschiene 4 ist mit einer in Längsrichtung verlaufenden Reihe von kreisrunden Löchern 6 versehen, deren Ränder 7 leicht nach oben gebogen sind. Der Durchmesser dieser Löcher 6 ist etwas kleiner gewählt als der Durchmesser von Kugelrollen 8, die die Auflagefläche der Traverse bilden und deren größerer Teil im Inneren der Traverse Hegt. _As Figure 2 shows, an upper U-profile rail 4 is placed on the lower U-profile rail 1, the downwardly pointing legs take up the upwardly pointing legs of the lower profile rail 1. The two U-profile rails 1 and 4 releasably connected by means of screws S form a traverse. The overhead yoke part of the upper U-profile rail 4 is provided with a longitudinal direction Series of circular holes 6 provided, the edges 7 of which are slightly bent upwards. The diameter this holes 6 is chosen to be slightly smaller than the diameter of ball rollers 8, which the support surface form the traverse and the greater part of which lies inside the traverse. _

Jede Kugelrolle 8 liegt auf Kugeln 9 eines als Ganzes mit 10 bezeichneten Lagers auf. Die Kugeln sind in einem Käfigring 11 gelagert und gleichmäßig auf dessen Umfang verteilt. Die Lager 10 sind auf einem schienenförmigen Träger 12 befestigt, der in die untere U-Profilschiene I eingelegt und gegen eine Querverschiebung durch deren Schenkel gesichert ist. Der Träger 12 liegt, wie Fig. 2 zeigt, nicht unmittelbar auf dem Jochteil der unteren Profilschine 1 auf. Vielmehr ist zwischen den Träger 12 und diesen Jochteil ein schienenförmiger Abstandhalter 13 eingeschoben. Die Höhe dieses Abstandhalters 13 ist so gewählt, daß die Lager 10 die Kugelrollen 8 in einer solchen Höhe halten, daß sie mit geringem Spiel in das zugeordnete Loch 6 rap η.Each ball roller 8 rests on balls 9 of a bearing designated as a whole as 10. The bullets are stored in a cage ring 11 and evenly distributed over its circumference. The bearings 10 are on one rail-shaped support 12 attached, which is in the lower U-profile rail I inserted and against a transverse displacement is secured by the legs. As FIG. 2 shows, the carrier 12 is not located directly on the yoke part of the lower profile rail 1. Rather, between the carrier 12 and this yoke part a rail-shaped spacer 13 is inserted. The height of this spacer 13 is chosen so that the bearings 10 hold the ball rollers 8 at such a height that they are in the associated with little play Hole 6 rap η.

Das Reinigen der Lager 10 kann in zweierlei Weise erfolgen. Entweder werden die Schrauben 5 gelöst und sodann die obere Profilschiene 4 abgehe ben. Die Lager 10 können dann in der normalen Gebrauchslage gereinigt werden. Selbstverständlich kann aber auch der Träger 12 aus der Schiene 1 herausgenommen werden. Will man die Schrauben 5 nicht lösen oder sind die beiden Schienen 1 und 4 unlösbar miteinander verbunden, so braucht nur der Abstandhaltei 13 aus der Profilschiene 1 in deren Längsrichtung herausgezogen zu werden. Der Träger 12 kann dann so weit abgesenkt werden, daß die Kugelrolien 8 nicht mehr in die Löcher 6 ragen, so daß auch der Träger 12 aus der Traverse 1,4 herausgezogen werden kann. Der Einbau nach der Reinigung erfolgt in der umgekehrten Reihenfolge.The bearings 10 can be cleaned in two ways. Either the screws 5 solved and then the upper rail 4 abhe ben. The bearings 10 can then be in the normal position of use getting cleaned. Of course, the carrier 12 can also be removed from the rail 1 will. If you do not want to loosen the screws 5 or the two rails 1 and 4 cannot be loosened connected to each other, so only needs the spacer 13 from the profile rail 1 in their To be pulled out lengthways. The carrier 12 can then be lowered so far that the ball races 8 no longer protrude into the holes 6, so that the carrier 12 is also pulled out of the traverse 1,4 can be. Installation after cleaning is carried out in the reverse order.
