Description

Die Erfindung betrifft einen Laufwagen mit höhenverstellbarer Lagereinheit (eine Höhenverstellung erlaubende/ermöglichende Lagereinheit) für einen Flügel als Abstellschiebetür oder -Fenster. Ein an dem Laufwagen schwenkbar angeordneter Ausstellarm wird höhenverstellbar mit einem an einem unteren Flügelprofil (Flügelrand) anbringbaren Stützprofil verbunden bzw. gekoppelt. Ebenso erfasst die Erfindung ein Verfahren des Arbeitens dieser Lagereinheit.The invention relates to a carriage with height-adjustable storage unit (a height adjustment permitting / enabling storage unit) for a wing as Abstellschiebetür or window. A pivotally arranged on the carriage extension arm is height-adjustable connected or coupled with a mountable on a lower wing profile (wing edge) support profile. Likewise, the invention covers a method of operating this storage unit.

Lagereinheiten für Abstellflügel sind bekannt und dienen dazu, bei der Montage auftretende oder festgestellte Toleranzen durch geringes Anheben oder Absenken des genannten Flügels auszugleichen, vgl. für große Türen (Hangartüren) die US-A1,899,175 (Willard ).Bearing units for Abstellflügel are known and serve to compensate for occurring or detected tolerances during assembly by slightly raising or lowering the said wing, see. for large doors (hangar doors) the US-A1,899,175 (Willard ).

Für parallel abstellbare Flügel ist eine solche Lagereinheit aus der EP-A1 378 624 (Siegenia) bekannt, bei der ein Lagerbolzen, dessen unteres Ende fest mit dem Ausstellarm verbunden ist, an seinem oberen Ende mit einer radial mehrfach abgestuften axialen Einsenkung (als Senkloch) versehen ist, in die ein Zapfen-Verstellelement eingreift, wobei zwischen dem Boden der Einsenkung und der flachen Unterseite des Verstellelements eine Kugel angeordnet ist, auf der sich das - in einer Gewindeöffnung eines mit dem Flügelrahmen fest verbundenen Gehäuseteils (dort 20) schraubbare - Verstellelement im wesentlichen punktförmig axial abstützt. Das Verstellelement, das die Flügellast auf den Lagerbolzen überträgt, kann nur eine - gegenüber dem Bolzen - vergleichsweise geringe radiale Abmessung aufweisen, da es bis zur Berührung mit der Kugel tief in das obere Ende des Lagerbolzens eintauchen muss. Dieses Element und die zugehörigen Gewindebereiche sind daher "hoch belastet". Es sind für die Teile somit hochwertige Materialien erforderlich.For parallel shut off wing is such a storage unit of the EP-A1 378 624 (Siegenia), in which a bearing pin whose lower end is fixedly connected to the stay, at its upper end with a radially multi-stepped axial recess (as a counterbore) is provided, in which a pin-adjusting element engages, wherein between the bottom the depression and the flat bottom of the adjusting element is arranged a ball on which the - in a threaded opening of a fixedly connected to the casement housing part (there 20) screwable - adjusting substantially axially punctiform supported. The adjustment, which transmits the wing load on the bearing pin, only one - relative to the bolt - have comparatively small radial dimension, since it must dive deeply into the upper end of the bearing pin to the touch with the ball. This element and the associated threaded areas are therefore "heavily loaded". Thus, high quality materials are required for the parts.

In der genannten US-A1,899,175 ist ein Laufrad für eine auf einer Spur geführte Tür gezeigt. Das Laufrad wird über eine Kugel an einem vertikal - durch ein Drehen - verstellbaren Einstellbolzen gestützt, dort Seite 2, Zeilen 9 bis 32.In the mentioned US A1,899,175 An impeller for a guided on a track door is shown. The impeller is supported by a ball on a vertical - by turning - adjustable adjusting bolt, there page 2, lines 9 to 32.

Andere Arten von vertikalen Stützlagern in Scharnieren, die mit einer Stützkugel arbeiten, sind aus US 2,096,311 (Strough), AU-B63 582/86 (Highland Bond) und GB 2 071 201 (Walter Pfäffli) bekannt.Other types of vertical support bearings in hinges that work with a support ball are off US 2,096,311 (Strough) AU-B63 582/86 (Highland Bond) and GB 2 071 201 (Walter Pfäffli) known.

Es ist Aufgabe der Erfindung eine höhenverstellbare Lagereinheit für einen Ausstellarm an einem Laufwagen vorzuschlagen, welche sowohl bezüglich der Herstellung wie auch bezüglich der einzusetzenden Materialien für ihre Teile einfach und kostengünstig ist. Dabei soll eine Tragfähigkeit oberhalb 150 kg bis hin zu 200 kg erreicht werden, bzw. erreichbar sein (für zwei Laufwägen oder zwei Lager, die einen Flügel tragen).It is an object of the invention to provide a height-adjustable storage unit for a stay on a carriage, which is both in terms of production as well as with respect to the materials used for their parts easy and inexpensive. In this case, a load capacity above 150 kg up to 200 kg should be achieved or be achievable (for two carriages or two bearings that carry a wing).

Diese Aufgabe wird mit Anspruch 1 oder 19, alternativ als Arbeitsverfahren nach Anspruch 17 gelöst.This object is achieved by claim 1 or 19, alternatively, as a working method according to claim 17.

Der Lagerbolzen ist mit seinem "unteren Ende" formschlüssig im Ausstellarm gehalten, insbesondere eingepresst. Sein "oberes Ende" ist im Durchmesser gegenüber dem Durchmesser des übrigen Lagerbolzens verringert und weist eine unflache (halbkugel- oder kegelförmige) Stirnfläche auf. Dieses "profilierte" Ende greift von unten in eine dem verringerten Durchmesser entsprechend angepasste Aufnahmeöffnung eines tragenden Lagerteils ein (Anspruch 1). Die Abstützung auf kleiner Fläche kann auch invertiert werden, wenn der Boden der Aufnahmeöffnung kleinflächig nach unten endet, und sich auf der Stirnfläche des Lagerbolzens abstützt (Anspruch 19). In beiden Fällen erfolgt die Kraftübertragung nach Art einer Spurzapfenlagerung, auf kleinster Fläche. Ein Vergleich der Krümmungsradien macht das anschaulich. Unten sind größere Radien, oder eine ebene Fläche, oben sind kleinere Krümmungsradien, bis zu einem spitzen Kegel.The bearing pin is positively held with its "lower end" in the extension arm, in particular pressed. Its "upper end" is reduced in diameter over the diameter of the rest of the bearing pin and has a flat (hemispherical or conical) face. This "profiled" end engages from below into a receiving opening adapted to the reduced diameter of a bearing bearing part (claim 1). The support on a small surface can also be inverted when the bottom of the receiving opening ends small area down, and is supported on the end face of the bearing pin (claim 19). In both cases, the power transmission takes place in the manner of a Spurzapfenlagerung, on the smallest area. A comparison of the radii of curvature makes this clear. Below are larger radii, or a flat surface, above are smaller radii of curvature, up to a pointed cone.

Damit können die Abmessungen des tragenden Lagerteils und seine zur Verstellung dienenden Koppelelemente, wie Außengewinde, groß genug gewählt werden, um Axiallasten eines schweren Flügels sicher aufnehmen und auf den Lagerbolzen übertragen zu können, bspw. größer 150 kg bis 200 kg Flügelgewicht (das sich auf üblicherweise zwei Laufwagen aufteilt).Thus, the dimensions of the bearing bearing part and its serving for adjustment coupling elements, such as external thread, be large enough to accommodate axial loads of a heavy wing safely and transferred to the bearing pin can, for example. Greater 150 kg to 200 kg sash weight (based on usually divides two carriages).

Eine offene Aufnahme an der Unterseite des tragenden Lagerteils ist als einfache zylindrische Ausnehmung mit glattem, ebenem Boden ausgebildet. Auch ohne gesonderte Kugel als Übertragungsglied kann die axiale Lastübertragung zwischen dem tragenden Lagerteil und dem Lagerbolzen kleinflächig bis praktisch punktförmig erfolgen. Das ist für eine Drehbewegung des Lagerbolzens gegenüber dem tragenden Lagerteil von Vorteil. Die kleine Fläche ist dabei entweder von oben oder von unten veranlasst oder vorgegeben (Ansprüche 1, 19).An open receptacle on the underside of the bearing bearing part is formed as a simple cylindrical recess with a smooth, flat bottom. Even without a separate ball as a transmission member, the axial load transfer between the bearing bearing part and the bearing pin small area to practically punctiform occur. This is for a rotational movement of the bearing pin relative to the bearing bearing part of advantage. The small area is initiated or predetermined either from above or from below (claims 1, 19).

Radiale Lager halten den Lagerbolzen drehbar und axial verschiebbar. Durch diese Lager wird das (radiale) Reibmoment stark herabgesetzt (Anspruch 4). Ihr Abstand kann zur Aufrechterhaltung der Achsrichtung groß gewählt werden (Anspruch 5, 14,15).Radial bearings keep the bearing pin rotatable and axially displaceable. Through these bearings, the (radial) friction torque is greatly reduced (claim 4). Their distance can be chosen to maintain the axial direction large (claim 5, 14,15).

Da bei dieser Ausbildung nur sehr geringe Reibkräfte (beispielsweise in radialer/tangentialer Richtung) auf das tragende Lagerteil einwirken, kann auf eine aufwändige Sicherung gegen selbsttätiges Verdrehen bei der Schwenkbewegung des Ausstellarmes verzichtet werden. Die Reibung (das Reibmoment) wird durch die Spurzapfenlagerung gesenkt. Die Wirklinie der axialen Last fällt mit der Drehachse zusammen und der Wirkabstand der Reibung Fr geht gegen Null bzw. ist sehr nahe an der Achse. Dadurch wird das Reibmoment und die Reibleistung, wenn die Drehbewegung berücksichtigt wird, sehr gering. Dieses Reibmoment ist kleiner als ein Drehmoment, welches benötigt wird um das nach unten offene Lagerteil mit seinem Gewinde in dem Gewindeöffnung des Stützprofils zu bewegen. Somit braucht das Lagerteil nicht gegen Verdrehung gesichert zu werden.Since only very small frictional forces (for example, in the radial / tangential direction) act on the supporting bearing part in this embodiment, an elaborate safeguard against automatic rotation during the pivoting movement of the extension arm can be dispensed with. The friction (the friction torque) is lowered by the Spurzapfenlagerung. The line of action of the axial load coincides with the axis of rotation and the effective distance of the friction F r approaches zero or is very close to the axis. As a result, the friction torque and the friction power, when the rotational movement is taken into account, very low. This friction torque is smaller than a torque which is required to move the downwardly open bearing part with its thread in the threaded opening of the support profile. Thus, the bearing part does not need to be secured against rotation.

Die beanspruchte Lagereinheit ist einfach im Aufbau, in der Herstellung und in der Montage und ihr tragendes Lagerteil kann aus weniger hochwertigen Werkstoffen (bspw. Zinkdruckguss) bestehen, insbesondere, wenn am Boden der nach unten offenen Aufnahme im tragenden Lagerteil eine Scheibe aus hochfestem Material zur Übertragung der Axialkräfte angeordnet wird (Anspruch 10), beispielsweise härtbarer Stahl, hoch legierter Stahl, Federstahl oder ein Sinterwerkstoff. Sie kann auch spitz nach unten auslaufen, um auf einer flächigeren Stirnfläche aufzusitzen.The claimed storage unit is simple in construction, in the manufacture and in the assembly and their bearing bearing part may consist of less high-quality materials (eg zinc die casting), especially if at the bottom of the downwardly open receptacle in the bearing bearing part a disc of high-strength material for Transmission of axial forces is arranged (claim 10), for example, hardenable steel, high alloy steel, spring steel or a sintered material. It can also taper down to sit on a more flat face.

Die innere Wand der nach unten offenen Aufnahmeöffnung ist bevorzugt im Wesentlichen zylindrisch. Allein eine quer verlaufende Aufnehmung für einen Sicherungsstift kann vorgesehen sein, um eine sichere Kopplung zu erreichen. Der Lagerbolzen wird so gegen ein Herausziehen aus der Aufnahmeöffnung des tragenden Lagerteils gesperrt (Anspruch 6). Ein "Sicherungsmaterial" ist insoweit ein Stift, ein Ring oder ein klemmender Werkstoff.The inner wall of the downwardly open receiving opening is preferably substantially cylindrical. Only a transverse Aufnehmung for a locking pin can be provided to achieve a secure coupling. The bearing pin is locked against withdrawal from the receiving opening of the bearing bearing part (claim 6). A "securing material" is insofar a pin, a ring or a clamping material.

Bevorzugt für die geringe Reibung sind geeignete Materialpaarungen, das tragende Lagerteil aus Zinkgussdruck, sowie der Lagerbolzen aus härtbarem Stahl und die Druckplatte/Scheibe aus Keramik oder Sinterwerkstoff.Preferred for the low friction are suitable material pairings, the bearing bearing part made of zinc casting, as well as the bearing pin made of hardenable steel and the pressure plate / disc made of ceramic or sintered material.

Die Druckplatte/Scheibe kann alternativ aus Federstahl gebildet werden. Nicht geeignet sind beispielsweise Kunststoffe oder Leichtmetalle.The pressure plate / disc may alternatively be formed of spring steel. Not suitable are, for example, plastics or light metals.

Ein Spalt sorgt für einen nicht spürbaren Reibungsbeitrag (Anspruch 5, Anspruch 12) von der radialen Seite, so dass die Spurzapfenreibung alleine bestimmend ist. Die Reibbeträge der Nadelhülsen sind klein, bis ganz unerheblich. Die Platte oder Scheibe (Anspruch 10) dreht in der Regel nicht selbst gegenüber ihrer Lagerfläche (oben), stützt nur den Spurzapfen des Lagerbolzens ab (in unflacher Form auf der einen oder anderen Seite).A gap provides a non-noticeable friction contribution (claim 5, claim 12) from the radial side, so that the Spurzapfenreibung alone is determinative. The amounts of friction of the needle sleeves are small, to very insignificant. The plate or disc (claim 10) does not turn itself against its bearing surface (above), supports only the track journal of the bearing pin (in flat form on one side or the other).

Die Buchse (Anspruch 13) hat die Radiallager vormontiert und kann in das Tragprofil eingeschoben werden, insbesondere eingesetzt werden. Tragarm und Achse wird dann montiert, durch die Nadellager hindurch, wobei das tragende Lagerteil mit eingesetztem Endabschnitt durch die Lager der Buchse geschoben werden. Es erfolgt dann ein Eindrehen dieses tragenden Lagerteils in das Gewinde des Tragprofils.The bushing (claim 13) has the radial bearings preassembled and can be inserted into the support profile, in particular used. Support arm and axle is then mounted, through the needle bearings through, the bearing bearing part are inserted with inserted end portion through the bearings of the socket. It then takes a screwing this bearing bearing part in the thread of the support profile.

In Figur 1 sind die üblichen Teile gezeigt, denen die höhenverstellbare Lagereinheit 10 zugeordnet ist. Mit 1 ist ein mit dem unteren Rand des Flügelrahmens fest verbindbares Stützprofil bezeichnet, das über die Lagereinheit 10 mit dem darunter liegenden Ausstellarm 8 höhenverstellbar verbunden ist oder werden soll. Der Ausstellarm selbst ist mit seinem anderen Ende über ein Gelenk mit dem Laufwagen 11 verbunden. Der Laufwagen 11 wird über eine Stange S mit einem weiteren, beabstandeten Laufwagen gekoppelt. In Figur 1 ist von der Lagereinheit 10 nur die obere Kontur 17 für den Eingriff eines Verstellwerkzeuges zu sehen.In FIG. 1 the usual parts are shown, which is associated with the height-adjustable storage unit 10. 1 with a fixed to the lower edge of the sash support profile is referred to, which is connected via the bearing unit 10 with the underlying extension arm 8 adjustable in height or to be. The extension arm itself is connected at its other end via a hinge with the carriage 11. The carriage 11 is coupled via a rod S with another, spaced carriage. In FIG. 1 is to be seen by the bearing unit 10, only the upper contour 17 for the engagement of an adjusting tool.

In Figur 2 sind die Teile der höhenverstellbaren Lagereinheit 10 - mit Ausnahme des Lagerbolzens 4 - in einer die Achse 100 des Lagerbolzens enthaltenden senkrechten Ebene geschnitten dargestellt. Wie ersichtlich, ist der Lagerbolzen 4 mit seinem unteren Abschnitt 4a formschlüssig in einer entsprechenden Aufnahme des Ausstellarms 8 gehalten, insbesondere eingepresst. Sein "mittlerer" Längenbereich 4b als Zwischenabschnitt ist in einer Axialbohrung 18 des Stützprofils, das vorzugsweise als Leichtmetall-Strangprofil ausgebildet ist, mittels zweier Radiallager 2a und 2b dreh- und axial verschiebbar gelagert.In FIG. 2 the parts of the height-adjustable bearing unit 10 - with the exception of the bearing pin 4 - shown cut in a vertical axis containing the axis 100 of the bearing pin. As can be seen, the bearing pin 4 is positively held with its lower portion 4a in a corresponding receptacle of the extension arm 8, in particular pressed. Its "middle" length region 4b as an intermediate portion is mounted in an axial bore 18 of the support profile, which is preferably formed as a light metal extruded profile, by means of two radial bearings 2a and 2b rotatable and axially displaceable.

Diese beiden Lager, die in Figur 2 als Nadelhülsen dargestellt sind, haben einen möglichst großen Abstand in Richtung der Achse 100. Der Abstand der Mitten der Lager ist größer als die Hälfte der Tiefe der Bohrung 18. Diese passt sich radial zwischen zwei vertikalen Schürzen 1a,1b des Hohlprofils ein. Eine eventuelle Zwischenwand 1c wird von der Bohrung 18 durchbrochen, die bis zum oberen Profilsteg 1d reicht.These two camps in FIG. 2 The distance between the centers of the bearings is greater than half the depth of the bore 18. This fits radially between two vertical aprons 1a, 1b of the hollow profile. A possible intermediate wall 1c is pierced by the bore 18, which extends to the upper profile web 1d.

Zur leichten Montage sind die beiden Lager 2a, 2b vorzugsweise in einer Buchse 3 vormontiert, die in die Bohrung 18 eingesetzt und mit ihrem unteren Bereich 3a in der Axialbohrung 18 des Stützprofils eingepresst verankert wird.For ease of assembly, the two bearings 2a, 2b are preferably preassembled in a bushing 3, which is inserted into the bore 18 and is anchored with its lower portion 3a pressed into the axial bore 18 of the support profile.

In seinem oberen Endbereich 4c ist der Lagerbolzen zu einem gegenüber dem axial belasteten Zwischenabschnitt 4b auf d2 verjüngten zylindrischen Abschnitt ausgebildet. Seine Stirnfläche 4d ist konvex oder kegelförmig profiliert gestaltet. Dies sind Beispiele von unflachen Formen, die eine kleine Stützfläche für eine Kraftübertragung eröffnen. Im Abstand von dieser Stirnfläche weist er eine umlaufende Nut 19 auf. Es ist ersichtlich, dass der Lagerbolzen 4 insgesamt eine einfache Gestaltung bei einem Durchmesser d1 im Zwischenabschnitt 4b aufweist, die sich in einfachen Bearbeitungsschritten herstellen lässt, auch bei Verwendung eines hochwertigen Stahls für den Lagerbolzen, der vorzugsweise gehärtet ist.In its upper end portion 4c of the bearing pin is formed to a relation to the axially loaded intermediate portion 4b on d2 tapered cylindrical portion. Its end face 4d is convex or conically profiled. These are examples of flat shapes that open up a small support surface for power transmission. At a distance from this end face, it has a circumferential groove 19. It can be seen that the bearing pin 4 has a total of a simple design with a diameter d1 in the intermediate portion 4b, which can be produced in simple processing steps, even when using a high-quality steel for the bearing pin, which is preferably cured.

In axialer Fluchtung mit dem Lagerbolzen 4 ist in dem Stützprofil 1 ein tragender Lagerteil 5 verstellbar angeordnet. Dieses Lagerteil weist eine von seiner unteren Stirnfläche ausgehende zylindrische Aufnahme 12 mit ebenem Boden 14 auf. Die Aufnahme 12 ist in ihren radialen und axialen Abmessungen im Wesentlichen an die Außenabmessungen des auf d1 verjüngten Endabschnitts 4c des Lagerbolzens angepasst. Die Anpassung erfolgt nur bis zur Belassung eines umfänglichen Spalts. Es ist ersichtlich, dass das tragende Lagerteil 5, das im Bereich seines oberen Endes die Kontur 17 zum Eingriff eines Verstellwerkzeuges aufweist, ein generell - das heißt außen wie innen - einfaches, leicht herzustellendes Profil aufweist.In axial alignment with the bearing pin 4, a supporting bearing part 5 is adjustably arranged in the support profile 1. This bearing part has an outgoing from its lower end face cylindrical receptacle 12 with a flat bottom 14. The receptacle 12 is adapted in its radial and axial dimensions substantially to the outer dimensions of the d1 tapered end portion 4c of the bearing pin. The adjustment takes place only until the leaving of a circumferential gap. It can be seen that the bearing bearing part 5, which has in the region of its upper end the contour 17 for engagement of an adjusting tool, a generally - that is outside and inside - simple, easy to manufacture profile.

Das tragende Lagerteil 5 hat einen Außendurchmesser d15, welcher nicht ganz dem des Lagerbolzens 4 in seinem Mittelabschnitt 4b entspricht. Damit wird erreicht, dass das Lagerteil 5 die vom Flügel verursachte Belastung in dem - auf seiner Außenseite vorgesehenen - Verstellgewinde 15 aufnehmen und über eine kleinflächige, insbesondere punktförmige Kontaktstelle mit dem Kopfprofil 4d des Lagerbolzens 4 auf diesen übertragen kann. Besonders vorteilhaft ist das leicht und sicher möglich. Bei kleiner Fläche ergibt sich keine hohe Reibkraft trotz hoher Axiallast.The bearing bearing part 5 has an outer diameter d15, which does not quite correspond to that of the bearing pin 4 in its middle section 4b. It is thereby achieved that the bearing part 5 can absorb the load caused by the wing in the adjustment thread 15 provided on its outside and can transmit it to the head profile 4d of the bearing pin 4 via a small-area, in particular punctiform contact point. This is particularly easy and safe possible. With a small area there is no high frictional force despite high axial load.

Der Lagerteil 5 braucht nicht aus einer hochwertigen Legierung hergestellt zu werden, insb. dann nicht, wenn zwischen seiner Bodenfläche 14 und dem Kopfprofil 4d des Lagerbolzens eine Scheibe 6 aus hochfestem Material angeordnet ist, wie dies die Figur 2 und Figur 3 zeigen. Als Werkstoffe eignen sich gesinterte Materialien, ggf. auch selbst schmierende Plattenstücke für eine weitere Reibungsverringerung. Der Boden 14 ist eben und drückt entweder direkt oder über die Scheibe 6 auf einen nur kleinen Bereich der unflachen Kopffläche 4d am oberen Ende des oberen Endabschnitts 4c. Gleiches ist auch umgekehrt zu realisieren, ohne gesonderte Darstellung. Die Scheibe hat ein spitz nach unten auslaufendes Ende, beispielsweise einen Kegel, oder eine Halbkugel, die kleinflächig auf einer nach oben weisenden Stirnfläche des Lagerbolzens aufsitzt.The bearing part 5 need not be made of a high-quality alloy, esp. Not if between its bottom surface 14 and the head profile 4 d of the bearing pin a disc 6 is arranged made of high-strength material, as the FIG. 2 and FIG. 3 demonstrate. Suitable materials are sintered materials, possibly also self-lubricating plate pieces for a further reduction in friction. Of the Bottom 14 is flat and presses either directly or over the disc 6 on only a small portion of the flat head surface 4d at the upper end of the upper end portion 4c. The same thing is to be realized vice versa, without separate presentation. The disc has a tapered end, for example, a cone, or a hemisphere, which sits on a small surface on an upwardly facing end face of the bearing pin.

Die zuvor schon erwähnte umlaufende Nut 19 im verjüngten Kopfteil 4c des Lagerbolzens dient zum Einbringen eines die Unverlierbarkeit des Lagerbolzens sichernden Materials, z.B. in Form eines in Figur 2 gezeigten handelsüblichen Spannstiftes 21, dessen Durchmesser etwas kleiner als die Nut ist, oder in Form eines Sicherungsringes (nicht gezeigt), oder in Form von in die Nut eingepressten Materials. Der Stift 21 sitzt in einer Querbohrung 20 auf der Höhe der Nut 19, aber im tragenden Lagerteil 5.The already mentioned circumferential groove 19 in the tapered head part 4c of the bearing pin is used for introducing a captive the bearing bolt locking material, for example in the form of an in FIG. 2 shown commercially available clamping pin 21, whose diameter is slightly smaller than the groove, or in the form of a retaining ring (not shown), or in the form of pressed-in material in the groove. The pin 21 is seated in a transverse bore 20 at the level of the groove 19, but in the bearing bearing part. 5

Die Höhenverstellung - als Arbeitsverfahren - erfolgt durch entsprechendes Drehen des Lagerteils 5 in dem Gewinde 16 einer axialen Durchbrechung im Stützteil 1. Von Vorteil ist, wenn der Außendurchmesser des Lagerteils 5 geringfügig kleiner ist, als der Durchmesser d2 des Mittelbereichs 4b des Lagerbolzens 4. Dadurch wird gewährleistet, dass bei einer axialen Verstellbewegung weit nach axial unten das Lagerteil 5 ohne weiteres in das obere Radiallager 2a eintauchen kann. Dadurch kann der gegenseitige Abstand der beiden Radiallager 2a, 2b groß gewählt werden. Die Stabilität und Kraftübertragung zur Buchse 3 und die axiale Ausrichtung 100 des Lagerbolzens werden so verbessert.It is advantageous if the outer diameter of the bearing part 5 is slightly smaller than the diameter d2 of the central region 4b of the bearing pin 4. As a result, by adjusting the bearing part 5 in the thread 16 of an axially ensures that in an axial adjustment movement far axially down the bearing part 5 can easily dip into the upper radial bearing 2a. Thereby, the mutual distance of the two radial bearings 2a, 2b can be made large. The stability and power transmission to the bushing 3 and the axial alignment 100 of the bearing pin are improved.

"Groß" ist nach den Figuren ein Abstand von Mittelebenen der beiden Radiallager 2a, 2b um mehr als die Hälfte der Tiefe der Bohrung 18 im Stützprofil 1."Large" is according to the figures, a distance from the center planes of the two radial bearings 2a, 2b by more than half the depth of the bore 18 in the support section. 1

Das Maß d2 ist möglichst groß, womit der Vorteil der guten Lastaufnahmefähigkeit und Lastübertragbarkeit des tragenden Lagerteils 5 aufgrund seines dem Lagerbolzen weitgehend entsprechenden Außendurchmessers erhalten wird.The dimension d2 is as large as possible, so that the advantage of the good load-bearing capacity and load transferability of the bearing bearing part 5 is obtained due to its outer diameter largely corresponding to the bearing pin.

Insgesamt ergibt sich bei der höhenverstellbaren Lagereinheit eine einfache, kostengünstig herstellbare Konstruktion bei minimalen Reibkräften in Axial- und Radialrichtung. Auch bezüglich der verwendeten Materialen ergeben sich Einsparungsmöglichkeiten.Overall, results in the height-adjustable storage unit a simple, inexpensive to produce construction with minimal friction forces in the axial and radial directions. Also regarding the materials used there are savings.

Vorteilhaft ist auch, dass die Einheit aus Lagerbolzen 4 und Lagerteil 5 bei in dem Stützprofil 1 vormontierter Führungseinheit aus Buchse 3 und den beiden Radiallagern 2a, 2b von unten her leicht eingebracht und montiert werden kann.It is also advantageous that the unit of bearing pin 4 and bearing part 5 can be easily inserted and mounted from below in the guide profile 1 preassembled guide unit from bushing 3 and the two radial bearings 2a, 2b from below.

Wenn, wie bevorzugt, der Außendurchmesser des Lagerteils 5 kleiner ist als der des Lagerbolzens 4, kann der Achsbolzen 4 danach durch die beabstandeten Lager 2a,2b geschoben werden.If, as is preferred, the outer diameter of the bearing part 5 is smaller than that of the bearing pin 4, the axle bolt 4 can then be pushed through the spaced bearings 2a, 2b.
