Description
Auszugseinrichtung für Schubladen. Bei bekannten Auszugseinrichtungen für Schubladen, bei denen beidseitig von den Schublade abstehende Schienen von an Füh- rungs;schienen eines Wagens montierten Rol len getragen werden, wobei diese Führungs schienen weitere Rollen tragen, mittels wel chen sie in fest angeordneten Laufschienen geführt :sind, :schwächen Aussparungen für die Rollen in den stark auf Biegung bean- spruehten Führungsschienen dieselben.
Da durch ist man gezwungen, diese Schienen entsprechend stark und schwer zu machen.
Die erTindungsgemäss.e Auszugsführung ist dadurch gekennzeichnet, dass .die Füh rungsschienen Z-f örmige.s Profil haben, an dessen Schenkeln die Lagerungen für die Tollen befestigt sind.
Die Rollen können da durch neben. :den Schenkeln und: die umum- gänglich. notwendigen Aussparungen im Steg angeordnet werden, der in oder zumindest ;sehr nahe an der neutralen Zone des auf Bie- gung beanspruchten Profils liegt.
Die Zeichnung stellt eine beispielsweise A.usfübrungsform des Erfindungsgegenstan des dar. Es zeigen: Fig. 7. einen Aufriss, Fig. 2 einen Grundriss, Fig. 3 einen Querschnitt und Fi.g.4 einen Schnitt längs der Linie IV-IV der Fig. 2.
An der Schublade 1 ist beidseitig eine L-Profilschiene 2 mit abstehendem Schenkel befestigt. Diese Schienen laufen zwischen zwei übereinanderäRegenden Rollenpaaren 3 und 4 und auf dem Rollenpaar 5. Die Rol len 4 und 5 sind spielfrei auf Zapfen gela gert, die festsitzen auf beidseitig -der Schub lade angeordneten, miteinander stabil zu einem Wagen verbundenen Führungsschie nen 6. Die Rollen 3 sind je auf Schwing hebeln 7 spielfrei gelagert, die auf ebenfalls an den Führungsschienen 'befestigten Zap fen 8 .drehbar sind.
Mit den Rollenpaaren 3, 5 und einem weiteren Rollenpaar 9, .das hin ten oben angeordnet ist, ist der ,Wagen in zwei fest angeordneten, U-förmigen Lauf schienen 10 geführt. Die Führungsschienen 6 ,des Wagens 'haben Z-förmiges Profil und die Zapfen der Rollen sind an deren senkrechten Schenkeln befestigt. Die Rollenpaare 3 und 5 ragen durch Aussparungen im Steg dieser Z-förmigen Schienen. hindurch, so dass sie die Schienen 2 tragen, ohne dass letztere mit den Führungbsschi.enen in sseTührung kommen.
Um die Zäpfen B der Schwinghebel sind Torsionss.ehraubenfedern 11. angeordnet, die sich mit einem Ende auf den Steg der Füh- rungssehienen abstützen und mit ihrem andern Ende die S.chwinghebe'1 zu heben trachten, so .dass die Rollen 3 immer oben an liegen.
Auf dem Wagen montierte Pufferfedern 1'2 und<B>13</B> stossen 'bei Erreichung der Extrem- stellungen der Schublade gegen am Möhel resP. an der Schublade befestigte Bügel 14 und 15. Diese Pufferfedern sind, um Platz zu sparen, in. Abweichung von den üblichen, runden Pufferfedern, oval gedrückt.
Pull-out device for drawers. In known pull-out devices for drawers in which rails protruding from the drawer on both sides are carried by rollers mounted on guide rails of a carriage, these guide rails carrying additional rollers by means of which they are guided in fixed rails: Recesses for the rollers in the guide rails, which are subject to strong bending, weaken the same.
As a result, one is forced to make these rails correspondingly strong and heavy.
The pull-out slide according to the invention is characterized in that the guide rails have a Z-shaped profile, on the legs of which the bearings for the jugs are attached.
The roles can go through as well. : the thighs and: the affable. necessary recesses are arranged in the web, which is in or at least; very close to the neutral zone of the profile subject to bending.
The drawing shows an exemplary embodiment of the subject matter of the invention. They show: FIG. 7 an elevation, FIG. 2 a plan view, FIG. 3 a cross section and FIG. 4 a section along the line IV-IV of FIG 2.
On both sides of the drawer 1, an L-profile rail 2 with protruding legs is attached. These rails run between two superimposed pairs of rollers 3 and 4 and on the pair of rollers 5. The rollers 4 and 5 are stored free of play on pins that are stuck on both sides of the drawer and are stably connected to form a carriage 6. The guide rails Rollers 3 are each mounted on rocker levers 7 free of play, which are also rotatable on Zap fen 8 also attached to the guide rails.
With the pairs of rollers 3, 5 and another pair of rollers 9, .das is arranged back th above, the carriage is in two fixed, U-shaped rails 10 out. The guide rails 6 of the carriage have a Z-shaped profile and the pins of the rollers are attached to their vertical legs. The roller pairs 3 and 5 protrude through recesses in the web of these Z-shaped rails. so that they carry the rails 2 without the latter coming into contact with the guide rails.
Around the pegs B of the rocker arms, torsion cage springs 11 are arranged, which are supported at one end on the web of the guide rails and at their other end strive to lift the rocker arms 1 so that the rollers 3 are always on top issue.
Buffer springs 1'2 and <B> 13 </B> mounted on the trolley hit against the Möhel resP when the extreme position of the drawer is reached. Brackets 14 and 15 attached to the drawer. In order to save space, these buffer springs are pressed into an oval shape. In contrast to the usual round buffer springs.
