Description

Die Erfindung betrifft eine teleskopierbare Haltestange mit einer als Innenrohr ausgebildeteten Innenstange und einer als Außenrohr ausgebildeten Außenstange, wobei die Innenstange, die innerhalb der Außenstange geführt ist, relativ zu der Außenstange in einer Wahlstellung verrastbar ist.The invention relates to a telescopic support rod with an inner tube designed as an inner tube and an outer rod designed as an outer tube, wherein the inner rod, which is guided within the outer rod, can be locked relative to the outer rod in a selected position.

Derartige Haltestangen werden bspw. zur Aufhängung von Gardinen, Vorhänge etc. verwendet, insbesondere wenn unterschiedliche Abstände zu überbrücken sind.Handrails of this type are used, for example, for hanging curtains, curtains, etc., in particular if different distances have to be bridged.

Bei einer bekannten Haltestange der vorstehend bezeichneten Art (vgl. US-PS 2,974,805) ist das Innenrohr außenseitig mit einem Nocken ausgebildet, welcher gegen einen Anschlag des Außenrohres anliegt. Die Verstellung ist ohne weiteren Eingriff nur in einer Richtung möglich. Ansonsten muß das Innenrohr relativ zu dem Außenrohr verdreht werden, um den Nocken außer Eingriff mit dem Anschlag zu bringen.In a known support rod of the type described above (cf. US Pat. No. 2,974,805), the inner tube is formed on the outside with a cam which bears against a stop of the outer tube. The adjustment is only possible in one direction without further intervention. Otherwise, the inner tube must be rotated relative to the outer tube to disengage the cam from the stop.

Bei der aus der US-PS 2,519,996 bekannten Haltestange weist das Innenrohr gleichfalls außenseitig eine überlaufbare Rastausnehmung auf und ist der Anschlag des Außenrohres durch Federkraft in die Ausnehmung eingedrückt. Zudem ist noch ein Hüllrohr vorgesehen, um das vorstehende Innenrohr hinsichtlich der Ausnehmungen ohne weiteres benutzen zu können. Schließlich ist noch auf die DE-PS 69 928 zu verweisen. Hieraus ist eine teleskopierbare Stange mit zweiseitig über Zahnstangen ausfahrbare Verlängerungsteile bekannt. Diese sind in einer bestimmten Ausfahrstellung festsetzbar. Hierzu ist eine aufwendige Festsetzvorrichtung vorgesehen.In the case of the holding rod known from US Pat. No. 2,519,996, the inner tube also has an overflowable locking recess on the outside and the stop of the outer tube is pressed into the recess by spring force. In addition, a cladding tube is also provided in order to be able to use the protruding inner tube with regard to the recesses without any problems. Finally, reference is made to DE-PS 69 928. From this, a telescopic rod with extension parts that can be extended on two sides via toothed racks is known. These can be fixed in a certain extended position. For this purpose, an expensive fixing device is provided.

Die Erfindung beschäftigt sich mit der technischen Problematik, eine teleskopierbare Haltestange der oben bezeichneten Art bei einfacher Herstellbarkeit gebrauchstechnisch zu verbessern.The invention deals with the technical problem, a telescopic handrail of the above to improve the designated type with simple manufacturability.

Die Problematik ist zunächst und im wesentlichen beim Gegenstand des Anspruches 1 gelöst, wobei darauf abgestellt ist, daß das Innenrohr innenseitig einen überlaufbaren, axial abgestützen Rastnocken aufweist, der mit einem Anschlag des Außenrohres zur Aufnahme einer Axialkraft zusammenwirkt, wobei der Anschlag schwerkraftabhängig in und außer Eingriff mit dem Rastnocken steuerbar ist. Die Axialorientierung vermeidet Querkräfte auf die hohle Innenstange bzw. Außenstange, so daß sogar hierfür auf Schlitzrohre zurückgegriffen werden kann. Eine solche als Klemmstange wirkende Haltestange ist dadurch einfach handbar, daß der Anschlag schwerkraftabhängig in und außer Eingriff mit den Rastnocken steuerbar ist. Eine vorteilhafte Weiterbildung ist dadurch gegeben. daß der Rastnocken Weise derart weitergebildet, daß ihr Rastnocken stirnseitig des Innenrohres ausgebildet ist. Hierbei kann es sich um einen einstückig mit dem Innenrohr ausgebildeten Rastnocken handeln, was den Vorteil einer reduzierten Teilezahl hätte; alternativ wird jedoch vorgeschlagen, daß der Rastnocken als Einsatzteil des Innenrohres gestaltet ist und eine umlaufende Schulter aufweist, die an der Stirnfläche des Innenrohres anliegt. Dies hätte zugleich den Vorteil, daß die in aller Regel recht schmale Stirnfläche so eine Art Stirnschutz erhält. Außerdem ergibt sich für diese relativ hoher mechanischer Beanspruchung ausgesetzte Zone eine stabilisierend wirkende Doppelwandigkeit.The problem is solved first and foremost in the subject matter of claim 1, with the focus being that the inner tube has an overflowable, axially supported locking cam on the inside, which interacts with a stop of the outer tube for receiving an axial force, the stop depending on gravity in and out Engagement with the locking cam is controllable. The axial orientation avoids lateral forces on the hollow inner rod or outer rod, so that even slotted tubes can be used for this. Such a holding rod acting as a clamping rod is easy to handle in that the stop can be controlled depending on gravity in and out of engagement with the locking cams. This provides an advantageous further development. that the locking cam Formed in such a way that their locking cam is formed on the front side of the inner tube. This can be a locking cam formed in one piece with the inner tube, which would have the advantage of a reduced number of parts; alternatively, however, it is proposed that the latching cam is designed as an insert part of the inner tube and has a circumferential shoulder which bears against the end face of the inner tube. At the same time, this would have the advantage that the generally very narrow end face is given a kind of forehead protection. In addition, a stabilizing double wall results for this relatively high mechanical stress zone.

Bei einer teleskopierbaren Haltestange mit einer als Innenrohr ausgebildeten Innenstange und einer als Außenrohr ausgebildeten Außenstange, wobei die Innenstange die innerhalb der Außenstange geführt ist, relativ zu der Außenstange in einer Wahlstellung verrastbar ist, wobei mehrere Anschlagnocken vorgesehen sind, wird nun weiterhin vorgeschlagen, daß die Anschlagnocken des Außenrohres auf einer innerhalb des Außenrohres angeordneten Nockenstange ausgebildet sind. Die entsprechende, eine Stufenverstellung bringende Anschlagnocken-Folge führt praktisch zu einer Art Zahnstange in der Struktur von Sägezähnen, also mit einer steilen Flanke, welche gegen den Rastnocken tritt und einer fliehenden Flanke, die bei längenvergrößernder Teleskopbewegung einer Überlaufbarkeit in Bezug auf den Rastnocken bringt. Dabei erweist sich eine Maßnahme dahingehend als vorteilhaft, daß die Anschlagnocken quer zu einer Längenerstreckung des Außenrohres bewegbar sind. Diese Bewegbarkeit bringt das Ausklinken bzw. Ausrasten, um die nächste oder sonst gewünschte Stufen- bzw. Wahlstellung einzustellen. Vorteilhafterweise sind die Anschlagnocken lagenabhängig quer zur Längsertreckung des Außenrohres bewegbar. In der einen Lage stehen Rastnocken und Anschlagnocken in Eingriff; in der anderen Lage treten diese Nocken außer Eingriff zueinander. Weiter erweist es sich als vorteilhaft, daß die Anschlagnocken in einer axial federnden Halterung in dem Außenrohr befestigt sind. Die axial orientierte Federung wirkt im Sinne einer Verlängerung der teleskopierbaren Haltestange, stellt also ein zwischen den Grobverstell-Schritten stufenlos wirkendes Federpolster für die Haltestange bzw. Klemmstange dar. Um auch bei einer solchen Ausgestaltung das Ausklinken bzw. Einklinken von Rastnocken und Anschlagnocken zu ermöglichen, sind die Anschlagnocken (Nockenstange oder Nockenleiste) in der Halterung senkrecht zur Axialerstreckung bewegbar. Konkret sieht das so aus, daß die Halterung eine Schlitzführung in einer Richtung quer zur Längserstreckung des Außenrohres ausbildet, in welcher Schlitzführung ein Winkelabschnitt der Nockenleiste geführt ist. Weiter erweist es sich als günstig, daß die Federung im Rücken der Halterung liegt und ein Widerlager für eine Druckfeder im Endbereich des Außenrohres ausgebildet ist. Zudem ist es vorteilhaft, daß der Rohrquerschnitt von Innenrohr und Außenrohr unrund ist. Eine vorteilhafte Ausgestaltung besteht sodann in der Ausbildung eines ovalen Rohrquerschnitts bezüglich beider Rohre.In a telescopic support rod with an inner tube designed as an inner tube and an outer tube designed as an outer tube, wherein the inner rod which is guided within the outer rod can be locked in a selected position relative to the outer rod, with several stop cams being provided, it is now further proposed that the Stop cams of the outer tube are formed on a cam rod arranged inside the outer tube. The corresponding stop cam sequence, which brings about a step adjustment, practically leads to a kind of rack in the structure of saw teeth, i.e. with a steep flank that comes into contact with the locking cam and a fleeing flank that, in the case of a lengthening telescopic movement, brings overflow with respect to the locking cam. A measure proves to be advantageous in that the stop cams can be moved transversely to a length extension of the outer tube. This mobility brings notching or disengaging to set the next or otherwise desired step or selection position. The stop cams are advantageously position-dependent Movable transversely to the longitudinal extension of the outer tube. In one position, locking cams and stop cams are engaged; in the other position, these cams disengage from each other. It also proves advantageous that the stop cams are fastened in an axially resilient holder in the outer tube. The axially oriented suspension acts in the sense of an extension of the telescopic support rod, that is, it represents a spring cushion for the support rod or clamping rod, which acts continuously between the rough adjustment steps. In order to enable the release or engagement of latching cams and stop cams even in such a configuration, the stop cams (cam rod or cam bar) can be moved in the holder perpendicular to the axial extent. Specifically, this means that the holder forms a slot guide in a direction transverse to the longitudinal extension of the outer tube, in which slot guide an angular section of the cam bar is guided. It also proves to be favorable that the suspension lies in the back of the holder and an abutment for a compression spring is formed in the end region of the outer tube. It is also advantageous that the tube cross section of the inner tube and outer tube is out of round. An advantageous embodiment then consists in the formation of an oval tube cross section with respect to both tubes.

Bei einer teleskopierbaren Haltestange mit einer als Innenrohr ausgebildeten Innenstange und einer als Außenrohr ausgebildeten Außenstange, wobei die Innenstange, die innerhalb der Außenstange geführt ist, relativ zu der Außenstange in einer Wahlstellung verrastbar ist, erweist es sich sodann als vorteilhaft, daß eine Nockenleiste der Außenstange in der Innenstange geführt ist und schwerkraftabhängig in und außer Eingriff mit dem Rastnocken steuerbar ist. Hierdurch liegt gerade im Bereich der Verstellmechanik ein stabilisierend wirkender wechselseitiger, praktisch geschachtelter Durchgriff der die Verstelleinrichtung der Haltestange bildenden Bauteile vor. Die Teile stützen sich gegenseitig geführt ab. Das vermeidet Belastungsbeeinträchtigungen und erhält der Nockenleiste die erstrebte Umsteuerfähigkeit.In the case of a telescopic holding rod with an inner rod designed as an inner tube and an outer rod designed as an outer tube, the inner rod which is guided inside the outer rod being able to be locked in a selection position relative to the outer rod, it then proves to be advantageous that a cam bar of the outer rod is guided in the inner rod and can be controlled depending on gravity in and out of engagement with the locking cam. As a result, there is a stabilizing, mutual, practically nested penetration of the components forming the adjusting device of the holding rod, particularly in the area of the adjusting mechanism. The parts are mutually supported. This avoids negative effects on the load and gives the cam bar the desired reversibility.

Schließlich erweist es sich bei einer teleskopierbaren Haltestange mit einer als Innenrohr ausgebilden Innenstange und einer aus Außenrohr ausgebildeten Außenstange, wobei die Innenstange, die innerhalb der Außenstange geführt ist, relativ zu der Außenstange in einer Wahlstellung verrastbar ist als vorteilhaft, daß eine im Inneren der Außenstange angeordnete Nockenleiste mit einem Rastnocken der Innenstange überlaufbar zusammenwirkt.Finally, it proves to be the case with a telescopic support rod with an inner rod designed as an inner tube and an outer rod formed from an outer tube, the inner rod, which is guided inside the outer rod, being lockable in a selected position relative to the outer rod, such that one inside the outer rod arranged cam bar interacts with a locking cam of the inner rod overflow.

Inner tube 3 and outer tube 4 are realized as a slotted tube and consist of metal. In the oval cross-sectional shape of both tubes shown in FIG. 3, the longitudinal slot 3 'of the inner tube 3 is in the lower bulge zone and the 4' of the outer tube 4 is in the upper.

Es handelt sich um topfförmige, querschnittsangepaßte gummielastische Schuhe 5, deren Boden außenseitig noch mit einem hochelastischen Schaumstoffplättche 6 besetzt ist.The outward-pointing tube ends a, b of the holding rod H are shoeed. It is pot-shaped, cross-sectionally adapted rubber-elastic shoes 5, the bottom of which is still covered on the outside with a highly elastic foam plate 6.

Das Innenrohr 3 ist relativ zum Außenrohr 4 in einer Wahlstellung grob verrastbar. Sie ist stufenförmig erreichbar. Die entsprechende Rastvorrichtung V befindet sich im Bereich des linksseitigen, nach auswärts weisenden Rohrendes b. Dieser Bereich ist in Figur 6 offengeschnitten dargestellt. Besagte Rastvorrichtung V umfaßt einen in Teleskopverlängerungsrichtung verlagerbaren Rastnocken R. Der Rastnocken R sitzt am einwärtsweisenden Rohrende c des Innenrohres 3 und wirkt mit einem Anschlagnocken A des Außenrohres 4 zur Aufnahme einer Axialkraft zusammen.The inner tube 3 can be roughly locked relative to the outer tube 4 in a selected position. It can be reached in stages. The corresponding locking device V is located in the area of the left-hand, outward-pointing pipe end b. This area is shown in an open section in FIG. Said latching device V comprises a latching cam R which can be displaced in the telescopic extension direction. The latching cam R sits at the inward-pointing pipe end c of the inner pipe 3 and interacts with a stop cam A of the outer pipe 4 for receiving an axial force.

Die Axialkraft kann aus der Federfähigkeit der Schuhe 5 als elastische Puffer herrühren einschließlich der Wirkung der Schaumstoffplättchen 6 oder aber aus einem Speicher kommen in Form einer der Haltestange H einverleibten Druckfeder 7.The axial force can result from the resilience of the shoes 5 as an elastic buffer, including the effect of the foam plate 6, or else come from a memory in the form of a compression spring 7 incorporated into the holding rod H.

Gemäß der bevorzugten, dargestellten Ausgestaltung ist der Rastnocken R stirnseitig des Innenrohres 3 ausgebildet. Obwohl er einstückig mit besagtem Innenrohr sein kann, sieht die dargestellte Lösung seine Ausbildung als separat gestaltetes Einsatzteil 8 vor. Es handelt sich um einen stopfenförmigen, aus Kunststoff bestehenden, abgesetzten Körper, welcher mit einem Teil seiner axialen Länge im offenen Rohrende c des Innenrohres 3 steckt und mit einem anderen Teil frei über die dortige Stirnfläche 9 des Innenrohres 3 vorragt, wobei durch den erwähnten Absatz eine quer zur Stangenerstreckung verlaufende Schulter 10 besteht, die lagesichernd gegen die besagte Stirnfläche 9 tritt, in deren Richtung das Einsatzteil 8 via Rastnocken R in Funktionsstellung (Fig. 4) belastet ist. Es genügt bezüglich des Einsatzteiles ein reibungsbedingter Haftsitz. Das rechtsseitige Rohrende des Außenrohres 4 ist mit d bezeichnet.According to the preferred embodiment shown, the locking cam R is formed on the end face of the inner tube 3. Although it can be in one piece with said inner tube, the solution shown provides for its design as a separately designed insert 8. It is a stopper-shaped, made of plastic, stepped body, which is part of its axial length in the open pipe end c of the inner tube 3 and with another part protrudes freely over the end face 9 of the inner tube 3 there, by the paragraph mentioned there is a shoulder 10 which extends transversely to the rod extension and which secures the position against said end face 9, in the direction of which the insert part 8 is loaded into the functional position (FIG. 4) via locking cams R. A friction-related adhesive seat is sufficient with regard to the insert part. The right-hand pipe end of the outer pipe 4 is denoted by d.

Die eigentliche Rastflanke des Rastnockens R ist von der äußeren, quer zur Achsrichtung der Haltestange H liegenden Kopffläche 11 gebildet, gegen welche eine entsprechend ausgerichtete, also steile Flanke 12 des Anschlagnockens A tritt (vgl. Figur 9).The actual latching flank of the latching cam R is formed by the outer head surface 11 lying transversely to the axial direction of the holding rod H, against which a correspondingly aligned, ie steep flank 12 of the stop cam A occurs (see FIG. 9).

Der Rücken des Anschlagnockens A bildet eine Auflaufschräge 13, so daß der Anschlagnocken bei Vergrößerung der wirksamen Teleskoplänge der Haltestange H verhakungsfrei über eine jenseits der Kopffläche 11 des Einsatzteiles 8 liegende Rampe 14 laufen kann. Dabei wird eine ausweichende Bewegung erforderlich, die dadurch möglich ist, daß der Anschlagnocken A quer zu einer Längsstreckung der Haltestange H bewegbar ist. Dazu bildet das Einsatzteil 8 oberhalb des Abschnitts der Kopffläche 11, welche den Rastnocken R formt, eine Schlitzführung 15 aus. Letztere erstreckt sich über die gesamte Länge des Einsatzteiles 8 und durchdringt die Mantelwand des oberen auf den Rohrquerschnitt abgestimmten Krümmungsabschnitt dieses Einsatzteils. Somit liegt bezüglich 8 ein U-Profil vor. Auch im Übergangsbereich zur Rampe 14 liegt eine durchgehend gleiche Breite des Schlitzes 15 vor.The back of the stop cam A forms a run-up slope 13, so that the stop cam can run hook-free over a ramp 14 located beyond the top surface 11 of the insert part 8 when the effective telescopic length of the holding rod H is increased. An evasive movement is required, which is possible in that the stop cam A is movable transversely to a longitudinal extension of the support rod H. For this purpose, the insert part 8 forms a slot guide 15 above the section of the head surface 11 which forms the latching cam R. The latter extends the entire length of the Insert 8 and penetrates the outer wall of the upper curved section of the insert, which is matched to the tube cross section. Thus there is a U-profile with respect to FIG. 8. Also in the transition area to the ramp 14, the width of the slot 15 is the same throughout.

Der Schlitz 15 ist in Querrichtung gesehen von solcher Länge x, daß der sägezahnförmig gestaltete Anschlagnocken A quer aus dem Wirkungsbereich der Kopffläche 11 verlagert werden kann (vgl. Figur 6).The slot 15 is seen in the transverse direction of such a length x that the sawtooth-shaped stop cam A can be moved transversely out of the effective area of the head surface 11 (see FIG. 6).

Dies geschieht nicht nur bezüglich des beschriebenen Anschlagnockens A alleine, sondern zugleich bezüglich einer Anzahl gleich gestalteter, axial beabstandeter Anschlagnocken A, die zu einer sie tragenden Nockenleiste 16 zusammengefaßt sind. Diese praktisch wie ein Sägeblatt gestaltete, aus Metall bestehende Nockenleiste 16 ist in den Figuren 7 und 8 isoliert dargestellt. Sie steht mit dem Außenrohr 4 montagemäßig in Verbindung, d.h. sie ist innerhalb des Außenrohres 4 angeordnet. Sie (16) sitzt im Bereich des mit b bezeichneten Rohrendes und greift ein gutes Stück mit ihrem freien Ende 16', also mit Rastnocken R, in das Innere des Innenrohres 3 und wirkt so mit dem überlaufbaren Rastnocken R zusammen.This occurs not only with respect to the stop cam A described, but also with regard to a number of identically designed, axially spaced stop cams A, which are combined to form a cam bar 16 which supports them. This practically like a saw blade, made of metal cam 16 is shown in Figures 7 and 8 isolated. It is connected to the outer tube 4 in terms of assembly, i.e. it is arranged within the outer tube 4. It (16) sits in the area of the tube end labeled b and engages a good deal with its free end 16 ', that is to say with locking cams R, into the interior of the inner tube 3 and thus interacts with the locking cam R which can be overflowed.

Die Verbindung des fesselungsseitigen, also linksseitigen Endes der Nockenleiste 16 mit dem Außenrohr 4 geschieht über eine Halterung 17. Letztere fungiert zugleich als Druckstück und besteht aus einem der Innenkontur des Außenrohres 4 angepaßten Kunststoffkörper. Der ist im Außenrohr axial verlagerbar geführt.The connection of the restraint-side, that is to say the left-hand end of the cam strip 16 to the outer tube 4 takes place via a holder 17. The latter also acts as a pressure piece and consists of a plastic body adapted to the inner contour of the outer tube 4. The is guided axially displaceable in the outer tube.

Die Halterung 17 steht unter Belastung durch die erwähnte Druckfeder 7. Deren in Richtung des Rückens 17' der Halterung 17 gehende endständigen Windungen der Druckfeder sitzen auf einem frei stehenden Dorn 18. Letztere ist der Halterung 17 gleich angeformt. Ein gleiches Federlager finden die in Gegenrichtung weisenden endständigen Windungen der Druckfeder 7 vor, hier an einem Widerlager 19. Dieses besteht aus einem dem Außenrohr querschnittsangepaßten Kunststoffspritzteil, welches stopfenartig vom linksseitigen freien Ende der Haltestange H her in das Rohrende b eingesetzt ist. Der von der Brust 19' des Widerlagers 19 ausgehende, koaxial zum Dorn 18 liegende Dorn des Widerlagers trägt das Bezugszeichen 20. Die in der Längsmittelebene der Haltestange H liegenden, gegeneinander gerichteten der Dorne 18,20 sind gefast.The holder 17 is under load by the aforementioned compression spring 7. Its end windings of the compression spring going in the direction of the back 17 'of the holder 17 sit on a free-standing mandrel 18. The latter is molded onto the holder 17 in the same way. The end windings of the compression spring 7 pointing in the opposite direction find an identical spring bearing, here on an abutment 19. This consists of a plastic injection-molded part which is cross-sectionally adapted to the outer tube and which is inserted like a stopper from the left-hand free end of the holding rod H into the tube end b. The mandrel of the abutment, which extends from the breast 19 'of the abutment 19 and lies coaxially to the mandrel 18, bears the reference numeral 20. The mandrels 18, 20 directed towards one another in the longitudinal center plane of the holding rod H are chamfered.

In entspanntem Zustand nehmen die freien Enden der Dorne 18,20 einen dem entspannten Zustand der Druckfeder 7 entsprechenden axialen Abstand y zueinander ein, der bei Ladung dieses Kraftspeichers zur Aufbringung der Axialkraft sich, wie aus der Funktionsstellung in Figur 4 hervorgeht, deutlich verringert und dort mit y' bezeichnet ist. Die Axialkraft belastet via Anschlagnocken A und Rastnocken R das Innenrohr 3 nach auswärts. Der komprimierbare Abstand y entspricht in entspanntem Zustand etwa dem dreifachen Maß des axialen Abstandes z zwischen zwei benachbarten Anschlagnocken A (z beträgt ca. 10 mm).In the relaxed state, the free ends of the mandrels 18, 20 have an axial distance y from one another which corresponds to the relaxed state of the compression spring 7 and which, when the force accumulator is loaded to apply the axial force, significantly reduces and there, as can be seen from the functional position in FIG is denoted by y '. The axial force loads the inner tube 3 outwards via stop cams A and locking cams R. The compressible distance y corresponds in the relaxed state to approximately three times the axial distance z between two adjacent stop cams A (z is approximately 10 mm).

Die lagen- bzw. schwerkraftabhängige Ausklinkung des Anschlagnockens A bzw. der ganzen Nockenleiste 16 ist auch im Bereich der Halterung 17 baulich berücksichtigt. Zunächst zur Fesselung: diese besteht leistenseitig aus einer Abwinkelung 21. Die im Winkel von 90 Grad abgehende Abwinkelung greift in eine Schlitzführung 22 der Halterung 17 ein. Diese quer liegende Schlitzführung 22 öffnet zur gleichen Seite hin wie der Schlitz 15 des Einsatzteils 8, so daß bezüglich der Nockenleiste 16 eine gleichsinnige d.h. Parallelverschiebung stattfinden kann.The position-dependent or gravity-dependent notching of the stop cam A or the entire cam bar 16 is also taken into account structurally in the area of the holder 17. First of all about the bondage: this consists of a bend 21 on the groin side, the one going out at an angle of 90 degrees Bending engages in a slot guide 22 of the holder 17. This transverse slot guide 22 opens to the same side as the slot 15 of the insert part 8, so that with respect to the cam bar 16, a parallel displacement can take place.

Dem als Querschlitz realisierten Abschnitt der Schlitzführung steht ein fensterförmiger Abschnitt 23 benachbart, der den Durchtritt des Querschnitts der Nockenleiste 16 erlaubt. Aufgrund des fensterförmigen Abschnitts 23 verbleiben zwei seitliche Gabelzinken 24 stehen. Die Tiefe der Schlitzführung 23 berücksichtigt auch hier den Raumbedarf für die funktionsgerechte Querverlagerung.The section of the slot guide realized as a transverse slot is adjacent to a window-shaped section 23 which allows the cross section of the cam strip 16 to pass through. Because of the window-shaped section 23, two lateral fork tines 24 remain. The depth of the slot guide 23 also takes into account the space required for the functional transverse displacement.

Die als Gebelzinken 24 auftretenen Partieen sind von geringerer Materialanhäufung als der sich auf der anderen Seite der Schlitzführung 23 fortsetzende Abschnitt, so daß dieser mit seiner schlitzführungsseitigen Fläche 25 die Belastung auf den durch Abwinklung versteiften zugleich flächenvergrößerten Endabschnitt der Nockenleiste 16 überträgt. Ein Teil des Schlitzgrundes im Abschnitt 23 weist eine Abschrägung 26 auf.The parts occurring as prongs 24 are of a smaller material accumulation than the section continuing on the other side of the slot guide 23, so that with its slot guide-side surface 25 it transmits the load to the end section of the cam bar 16, which is stiffened by angling and at the same time area-enlarged. Part of the slot base in section 23 has a bevel 26.

Der im Rücken 17' der Halterung 17 ansetzende Dorn 18 wurzelt im Zentrum des Querschnitts der Halterung 17.The mandrel 18 which is located in the back 17 ′ of the holder 17 is rooted in the center of the cross section of the holder 17.

Die Funktion ist, kurz zusammengefaßt, wie folgt: zum Einbringen der als Klemmstange fungierenden Haltestange H zwischen die Vertikalwände 1,2 wird grob der Teleskopabstand eingestellt, der aber über dem lichten Maß zwischen den beiden Vertikalwänden 1,2 liegt. Dann wird die in der Horizontalen gehaltene Haltestange H so gewendet, daß die Nockenleiste 16 mit ihren Anschlagnocken A gewichtsabhängig in die sperraktive Lage gemäß Figur 6 fällt. Dabei tritt die steile Flanke 12 des dem Rastnocken R nächstliegenden Anschlagnockens A vor die korrespondierende Kopffläche 11 des Rastnocken R. Dies bedarf nicht einmal der optischen Verfolgung. Der Montierende spürt die Verrrastung, da sich das Innenrohr 3 nun nur noch gegen Federwirkung unter Verkürzung der Haltestange H einschieben läßt. Dies geschieht gegen den deutlichen, zunehmenden Widerstand der Druckfeder 7 bzw. den einer äquivalenten Axialkraft. Es erfolgt das Einspannen der Haltestange H unter Loslassen des weiter als nötig eingeschobenen Innenrohres 3. Dieses federt aus. Die Klemmstellung liegt vor.The function is, briefly summarized, as follows: to insert the holding rod H, which acts as a clamping rod, between the vertical walls 1, 2, the telescopic distance is roughly set, but this is above the clear dimension between the two vertical walls 1, 2. Then the holding rod H held in the horizontal is turned so that the cam bar 16 with its stop cams A depends on the weight into the locked position according to FIG. 6 falls. The steep flank 12 of the stop cam A closest to the locking cam R comes in front of the corresponding head surface 11 of the locking cam R. This does not even require optical tracking. The assembler feels the latching, since the inner tube 3 can now only be pushed in against the spring action while shortening the holding rod H. This takes place against the clear, increasing resistance of the compression spring 7 or that of an equivalent axial force. The holding rod H is clamped in while releasing the inner tube 3 which is pushed further than necessary. This springs out. The clamping position is present.

Soll eine andere Weite eingestellt werden, wird die Haltestange H wiederum unter Eindrücken des Innenrohres 3 in das Außenrohr 4 aus der Nische zwischen 1 und 2 herausgenommen. Hier genügen praktisch wenige Millimeter, eben nur um den Freistand der Haltestange H zu erhalten. Dann wird die Haltestange H gewendet derart, daß der zuvor sperraktive Anschlagnocken A aus seiner Zuordnung zum Rastnocken R fällt, was aufgrund des beschriebenen Schlitzes 15 und der erörterten Schlitzführung 22 schwerkraftabhängig stattfindet. Die Nockenleiste 16 fällt also nach unten. Nun läßt sich die neue Weitenstellung festlegen usw.If a different width is to be set, the holding rod H is again taken out of the recess between 1 and 2 by pressing the inner tube 3 into the outer tube 4. Here, practically a few millimeters are enough, just to maintain the free handrail H. Then the support rod H is turned such that the previously locking stop cam A falls out of its assignment to the locking cam R, which takes place due to the described slot 15 and the slot guide 22 discussed gravity. The cam bar 16 thus falls down. Now you can set the new width position, etc.

Dieses Prinzip hat Gültigkeit für alle denkbaren Klemmstangen, besonders aber für Schlitzrohr-Gardinenstangen, da bei diesem System auf die Rohre Kein Innendruck ausgeübt werden darf.This principle applies to all conceivable clamping rods, but especially for slotted tube curtain rods, since no internal pressure may be exerted on the tubes with this system.
