Description
<B>Verstellbare metallene Stütze, z. B.</B> für <B>Bauzwecke</B> Gegenstand der Erfindung ist eine ver stellbare metallene Stütze, z. B. für Baa- zwecke, welche eine in einer äussern Hohl stange teleskopa.rtig verschiebbare innere Stange mit Aussengewinde und einen auf der letzteren verschiebbaren Ring mit zwei daran angelenkten Spannzangengliedern aufweist, welche lösbar im Eingriff mit dem Aussen gewinde der innern Stange stehen.
Gemäss der Erfindung sind die Spann- zangenglieder mit einer Aussenkonusflädie versehen, mittels welcher sie sich auf einer am obern Ende der äussern Stange den Spa.nn- za.ngeng(Iiedern zugekehilt angeordneten:Innen- konusfläche abstützen, um in ihrer Eingriffs lage gehalten zu werden. Ferner sind die Spannzangenglieder auf dem Innenkonus um die Stangenachse drehbar, um eine Feinver stellung der innern Stange relativ zur äussern Stange herbeizuführen.
Ein Ausführungsbeispiel der erfindungs gemässen Stütze ist auf der beiliegenden Zeichnung im Axialschnitt :dargestellt.
Die veranschaulichte Stütze weist zwei teleskopartig zueinander versehiebbare, rohr- förmige Stangen 10 und 11 -auf, von denen die äussere Stange 10 am untern Stirnende mit einer Fussplatte 12 und die innere Stange 11 auf einem Teil ihrer Länge auf der Aussenseite mit. einer gewindeartigen, aus- gerundeten Rillung 13 und am obern Stirn ende mit einer Abstützplatte 14 versehen ist.
An einem auf der Stange 11 axial verschieb- baren und drehbaren Gehäusering 15 sind zwei Spannzangenglieder 16 und 16' einander diametral gegenüber, in einer Axialebene des Ringes schwenkbar, mit ihrem obern Ende an je einem zylindrischen Wulst 17 bzw. 17' ein- gehängt. Das untere Ende der Spannzangen glieder 16 und 16' weist einen zum Eingriff in die Gewinderillung 13 bestimmten, abge rundeten Vorsprung 18 bzw. 18' und eine konische Aussenfläche 19 bzw.
19' auf, welche zum Abstützen an einem entsprechenden Innenkonus 20 eines am obern Stirnende der äussern Stange 10 befestigten Ringes 21 be stimmt ist, wodurch die Spannzangenglieder mit ihren Vorsprüngen 18 und 18' in der Ein griffslage gehalten werden.
Von den Spann- zangengliedern 16 lind 16' erstreckt sich je ein Arm 22 bzw. 22' durch je eine öffnung 23 bzw. 23' in dem die Glieder glockenaxtig überdeckenden Gehäusering 15 nach aussen, wo an den beiden Armen je ein in der Axial- ebene auf und ab. schwenkbarer Handgriff 24 bzw. 24' angelenkt ist. Die ganze Stütze ist aus Metall, z. B. Stahl, hergestellt.
Beim Ausziehen der beschriebenen Stütze durch Hochheben der innern Stange 11 wer den die Spannzangenglieder 16 und 16' vom Innenkonus 20 des Ringes 21 abgehoben und gleiten mitsamt dem Gehäusering. 15 auf der Stange 11, da die Vorsprünge 18 und 18' ohne die seitliche Druckwirkung des Innenkonus in der Gewinderillung keinen Halt finden, obgleich das Eigengewieht jedes Spannzan- gengliedes und seines Handgriffes den Vor sprung 18 bzw. 18' mit der Stangenaussen fläche in Berührung hält.
Ist die Stange 11 in annähernd gewünschter Länge ausgezogen, so gelangen die Spannzangenglieder 16 -und<B>1.6'</B> durch Abstützung am Innenkonus mit der Gewinderilhmg 13 selbsttätig wieder in festen Eingriff. Die Feineinstellung erfolgt durch Drehen des Gehäuseringes 15 und der Spannzangenglieder 16 und 16' mittels der Handgriffe 24 und 24' relativ zur Stange 11.
Ziun Zusammenschieben der Stütze wird diese zunächst entlastet, was durch Ver drehung des Gehäuseringes 15 gegenüber der Stange 11 geschehen kann. Dann werden die Handgriffe 24 und 24' nach oben in eine ,durch Anschläge begrenzte Lage geschwenkt, wodurch der Gehäusering 15 etwas gehoben wird und die Vorsprünge 18 und 18' der Spannzangenglieder aus der GewinderillLLng 13 austreten. Die Stange 11 geitet dann ab wärts.
<B> Adjustable metal support, e.g. B. </B> for <B> building purposes </B> The invention relates to a ver adjustable metal support, e.g. B. for Baa- purposes, which rod teleskopa.rtig in an outer hollow inner rod with external thread and a sliding ring on the latter with two articulated collet members, which are releasably in engagement with the external thread of the inner rod.
According to the invention, the collet members are provided with an outer conical surface by means of which they are supported on an inner conical surface arranged with a wedge on the upper end of the outer rod, in order to keep them in their engagement position Furthermore, the collet members can be rotated on the inner cone about the rod axis in order to bring about a fine adjustment of the inner rod relative to the outer rod.
An embodiment of the support according to the Invention is shown in axial section on the accompanying drawing.
The illustrated support has two tubular rods 10 and 11 which can be moved telescopically to one another, of which the outer rod 10 at the lower end with a footplate 12 and the inner rod 11 along part of its length on the outside. a thread-like, rounded groove 13 and is provided with a support plate 14 at the upper front end.
On a housing ring 15 that is axially displaceable and rotatable on the rod 11, two collet members 16 and 16 'are diametrically opposed to one another, pivotable in an axial plane of the ring, with their upper end suspended from a respective cylindrical bead 17 or 17'. The lower end of the collet members 16 and 16 'has a certain to engage in the thread groove 13, rounded projection 18 or 18' and a conical outer surface 19 or
19 ', which is to be supported on a corresponding inner cone 20 of a ring 21 attached to the upper end of the outer rod 10, whereby the collet members with their projections 18 and 18' are held in the A grip position.
From each of the collet members 16 and 16 ', an arm 22 or 22' extends outwards through an opening 23 or 23 'in the housing ring 15, which covers the members in a bell-ax-like manner, where on the two arms there is an axial level up and down. pivotable handle 24 or 24 'is articulated. The whole support is made of metal, e.g. B. steel.
When pulling out the support described by lifting the inner rod 11 who the collet members 16 and 16 'lifted from the inner cone 20 of the ring 21 and slide together with the housing ring. 15 on the rod 11, since the projections 18 and 18 'without the lateral pressure effect of the inner cone do not find a hold in the thread groove, although the inherent weight of each collet member and its handle makes the projection 18 and 18' with the rod outer surface in contact holds.
Once the rod 11 has been pulled out to an approximately desired length, the collet members 16 and 1.6 automatically come back into firm engagement with the threaded rail 13 by being supported on the inner cone. The fine adjustment is made by rotating the housing ring 15 and the collet members 16 and 16 'relative to the rod 11 by means of the handles 24 and 24'.
Ziun pushing together the support, this is initially relieved, which can be done by rotating the housing ring 15 relative to the rod 11. The handles 24 and 24 'are then pivoted upwards into a position limited by stops, as a result of which the housing ring 15 is lifted slightly and the projections 18 and 18' of the collet members emerge from the thread groove 13. The rod 11 then slides downwards.
