Definitions
- the invention relates to a device for the assembly of a door frame in a wall opening with a telescopic strut that can be adjusted to the clear distance between two vertical frame legs, two contact surfaces arranged on the front ends of the telescopic strut and facing the outside on the face side for the support organs having mutually facing inner surfaces of the frame legs NEN and one each on the support members by means of a manually operable actuating element with the interposition of a spring with a clamping surface against an inner surface facing away from the outer surface of the relevant frame leg clamping body.
- Devices of this type are used as an assembly aid when installing door frames, in order to align the opposite vertical frame legs parallel to one another and to hold them in this position until an assembly foam introduced between the frame legs and the wall opening has hardened.
- the assembly aid supported on the inner surfaces of the frame legs prevents the expanding assembly foam from moving or bending the frame legs towards one another.
- a mounting device of this type is known (US-A-2 806 495), the support members of which each have a vertical outwardly pointing vertical arm that can be struck against the edge of the frame and the wall surface, and its clamping body are designed as angle pieces that are designed with a leg parallel to the boom are guided in an opening of the respective support member and their clamping leg, which is here perpendicular, extends through an opening in the boom which also serves as a guide opening.
- the clamping body is actuated by means of a threaded bolt which slidably reaches through a bore in the support member and is positively connected with its outside end to the clamping leg of the clamping body and carries a handwheel guided on its thread at its inside end.
- two compression springs are arranged on the threaded bolt, of which an inner compression spring is supported between the handwheel and the inner surface of the support member and an outer compression spring between the clamping leg of the clamping member and the outer surface of the support member.
- an inner compression spring is supported between the handwheel and the inner surface of the support member and an outer compression spring between the clamping leg of the clamping member and the outer surface of the support member.
- both springs are tensioned by lifting the clamping body from the outer stop of its clamping leg until the clamping surface of the clamping leg lies against the outer surface of the frame. From this state on, when the handwheel is turned further in the tensioning direction, only the inner spring is tensioned and the frame with the appropriate force between Clamping legs and contact surface clamped. To release the assembly device, the handwheels are first rotated in the direction of relaxation of the springs until the clamping leg of the clamping body lifts off the outer surface of the frame. It is perceived as a disadvantage that the two support members must be clamped to the frame legs one after the other, since it is not possible to hold the telescopic strut horizontally at the same time and to turn both handwheels at the same time.
- Another disadvantage is that two compression springs counteracting the tensioning process are provided, the prestresses of which cancel each other out until the clamping leg rests against the outer surface of the frame leg during the tensioning process. Until the clamping leg rests, the two compression springs have only a spacing function, while in the subsequent tensioning process the differential tension between the two springs comes into effect.
- the invention is based on the object of improving the known assembly device in such a way that it is easier to handle and quicker and more reliable to assemble.
- the invention is based on the idea of being able to be clamped to the frame legs by spring force Support members to enable the mounting device to be attached or detached to both frame legs at the same time, in order to simplify and accelerate the workflow when installing the door frame.
- This is achieved according to the invention in that the clamping body, in its basic position defining a predetermined minimum distance between the clamping surfaces and the contact surface, rests against the base stop of the supporting member under the action of the spring, and in that the clamping member by means of the actuating member designed as a pressure member counteracts the spring force against Ver the distance between the clamping surface and the contact surface can be displaced relative to the contact surface.
- the clamping body can be stopped with the aid of the pressure element against the spring force against a preferably adjustable end stop defining a maximum distance between the clamping surface and the contact surface.
- the displacement distance of the clamping body can be reduced by the predetermined minimum distance when the support member is clamped.
- the minimum distance is expediently somewhat smaller than the smallest frame wall thickness that occurs in practice.
- the clamping body counteracts the spring force with the help of the pressure body against a preferably adjustable end stop that defines a maximum distance between the clamping surface and the contact surface. If this maximum distance is set only slightly larger than the wall thickness of the door frames to be installed, the displacement of the clamping bodies when clamping the support members and thus also the the effort required for this is reduced to a minimum.
- a preferred embodiment provides that the clamping body is preferably non-rotatably guided in a guide recess of the support member.
- a plurality of guide recesses are arranged on a cantilever of the support member and arranged at different distances from the telescopic strut for the optional insertion of the clamping body.
- the clamping body expediently has a guide pin guided in the guide recess of the support member and a preferably thin-walled clamping jaws formed on the free end of the guide pin and having the clamping surface.
- the guide pin advantageously has a pin part which projects outwards beyond the contact surface and which is delimited inwards by a stop shoulder forming the basic stop.
- Tilting of the assembly device in relation to the plane spanned by the door frame can, as is known, be prevented by the support members having an edge stop for the door frame which is offset parallel to the telescopic strut.
- the edge stop is expediently arranged on the clamping body and is advantageously formed by the protruding pin part of the guide pin. Tilting or pushing the door frame out of the wall opening through the Expanding assembly foam can be prevented if the clamping body additionally has a wall stop protruding on the end face, perpendicular to the clamping surface and offset parallel to the telescopic strut.

Description
Vorrichtung für die Montage einer Türzarge in einer WandöffnungDevice for mounting a door frame in a wall opening
Die Erfindung betrifft eine Vorrichtung für die Montage einer Türzarge in einer Wandöffnuπg mit einer auf den lichten Abstand zweier vertikaler Zargenschenkel ein¬ stellbaren Teleskopstrebe, zwei an stirnseitigeπ Enden der Teleskopstrebe angeordneten, stirnseitig nach außen weisende Anlageflächen für die einander zugewandten Innenflächen der Zargenschenkel aufweisenden Stützorga¬ nen und je einem an den Stützorganen mittels eines von Hand betätigbaren Betätigungsorgans unter Zwischenschal¬ tung einer Feder mit einer Klemmfläche gegen eine der Innenfläche abgewandte Außenfläche des betreffenden Zargenschenkels anpreßbaren Klemmkörper.The invention relates to a device for the assembly of a door frame in a wall opening with a telescopic strut that can be adjusted to the clear distance between two vertical frame legs, two contact surfaces arranged on the front ends of the telescopic strut and facing the outside on the face side for the support organs having mutually facing inner surfaces of the frame legs NEN and one each on the support members by means of a manually operable actuating element with the interposition of a spring with a clamping surface against an inner surface facing away from the outer surface of the relevant frame leg clamping body.
Vorrichtungen dieser Art werden als Montagehilfe beim Einbau von Türzargen eingesetzt, um die einander gegen¬ überliegenden vertikalen Zargenschenkel parallel zueinan¬ der auszurichten und in dieser Lage zu halten, bis ein zwischen Zargenschenkel und Wandöffnung eingebrachter Montageschaum ausgehärtet ist. Die an den Innenflächen der Zargenschenkel abgestützte Montagehilfe verhindert dabei, daß der sich ausdehnende Montageschaum die Zargen¬ schenkel aufeinanderzu verschiebt oder verbiegt.Devices of this type are used as an assembly aid when installing door frames, in order to align the opposite vertical frame legs parallel to one another and to hold them in this position until an assembly foam introduced between the frame legs and the wall opening has hardened. The assembly aid supported on the inner surfaces of the frame legs prevents the expanding assembly foam from moving or bending the frame legs towards one another.
Es ist eine Montagevorrichtung dieser Art bekannt (US-A-2 806 495) , deren Stützorgaπe je einen senkrecht nach außen weisenden, gegen die Zargenkante und die Wandfläche anschlagbaren senkrechten Ausleger und dessen Klemmkörper als Winkelstücke ausgebildet sind, die mit einem zum Ausleger parallelen Schenkel in einer Öffnung des jeweiligen Stützorgans geführt sind und deren hier¬ zu senkrechter Klemmschenkel durch einen zugleich als Führungsöffnung dienenden Durchbruch im Ausleger hin¬ durchgreift. Die Betätigung des Klemmkörpers erfolgt über einen Gewindebolzen, der verschiebbar durch eine Bohrung im Stützorgan hindurchgreift und mit seinem außenseitigen Ende formschlüssig mit dem Klemmschenkel des Klemmkörpers verbunden ist und an seinem innensei¬ tigen Ende ein auf seinem Gewinde geführtes Handrad trägt. Auf dem Gewindebolzen sind außerdem zwei Druck¬ federn angeordnet, von denen sich eine innere Druckfeder zwischen Handrad und Innenfläche des Stützorgans und eine äußere Druckfeder zwischen Klemmschenkel des Klemm¬ körpers und Außenfläche des Stützorgans abstützen. Beim Lösen des Handrades entspannen sich die beiden Federn, bis der Klemmschenkel des Klemmkörpers gegen die Außen¬ kante des Auslegerdurchbruchs anschlägt und dabei einen maximalen Abstand* zwischen Klemmfläche und Anlagefläche definiert. In diesem Zustand des Klemmkörpers wird die Montagevorrichtung auf die beiden einzuspannenden Zar¬ gen aufgeschoben, nachdem zuvor die lichte Weite an der Teleskopstrebe eingestellt wurde. Zum Festklemmen an den Zargen müssen sodann nacheinander die Handräder in Spannrichtung gedreht werden. Dabei werden zunächst beide Federn unter Abheben des Klemmkörpers vo Außen¬ anschlag seines Klemmschenkels gespannt, bis die Klemm¬ fläche des Klemmschenkels gegen die Zargenaußenfläche anliegt. Von diesem Zustand an wird beim Weiterdrehen des Handrads in Spannrichtung nur noch die innere Feder gespannt und die Zarge mit entsprechender Kraft zwischen Klemmschenkel und Anlagefläche eingespannt. Zum Lösen der Montagevorrichtung werden zunächst die Handräder in Entspannungsrichtung der Federn gedreht, bis sich der Klemmschenkel des Klemmkörpers von der Zargenaußenflä¬ che abhebt. Dabei wird einmal als nachteilig empfunden, daß das Festklemmen der beiden Stützorgane an den Zar¬ genschenkeln nacheinander erfolgen muß, da es nicht möglich ist, zu gleicher Zeit die Teleskopstrebe waage¬ recht zu halten und beide Handräder gleichzeitig zu drehen. Ein weiterer Nachteil besteht darin, daß zwei beim Spannvorgang entgegenwirkende Druckfedern vorge¬ sehen sind, deren Vorspannungen sich gegenseitig aufhe¬ ben, bis beim Spannvorgang der Klemmschenkel gegen die Außenfläche des Zargenschenkels anliegt. Bis zum Anlie¬ gen des Klemmschenkels haben die beiden Druckfedern ausschließlich eine Abstandshaltefuπktion , während beim anschließenden Spannvorgang die Differenzspannung zwi¬ schen den beiden Federn zur Wirkung kommt.A mounting device of this type is known (US-A-2 806 495), the support members of which each have a vertical outwardly pointing vertical arm that can be struck against the edge of the frame and the wall surface, and its clamping body are designed as angle pieces that are designed with a leg parallel to the boom are guided in an opening of the respective support member and their clamping leg, which is here perpendicular, extends through an opening in the boom which also serves as a guide opening. The clamping body is actuated by means of a threaded bolt which slidably reaches through a bore in the support member and is positively connected with its outside end to the clamping leg of the clamping body and carries a handwheel guided on its thread at its inside end. In addition, two compression springs are arranged on the threaded bolt, of which an inner compression spring is supported between the handwheel and the inner surface of the support member and an outer compression spring between the clamping leg of the clamping member and the outer surface of the support member. When the handwheel is released, the two springs relax until the clamping leg of the clamping body strikes against the outer edge of the boom opening and thereby defines a maximum distance * between the clamping surface and the contact surface. In this state of the clamping body, the assembly device is pushed onto the two frames to be clamped after the clear width has previously been set on the telescopic strut. To clamp onto the frames, the handwheels must then be turned one after the other in the tensioning direction. First, both springs are tensioned by lifting the clamping body from the outer stop of its clamping leg until the clamping surface of the clamping leg lies against the outer surface of the frame. From this state on, when the handwheel is turned further in the tensioning direction, only the inner spring is tensioned and the frame with the appropriate force between Clamping legs and contact surface clamped. To release the assembly device, the handwheels are first rotated in the direction of relaxation of the springs until the clamping leg of the clamping body lifts off the outer surface of the frame. It is perceived as a disadvantage that the two support members must be clamped to the frame legs one after the other, since it is not possible to hold the telescopic strut horizontally at the same time and to turn both handwheels at the same time. Another disadvantage is that two compression springs counteracting the tensioning process are provided, the prestresses of which cancel each other out until the clamping leg rests against the outer surface of the frame leg during the tensioning process. Until the clamping leg rests, the two compression springs have only a spacing function, while in the subsequent tensioning process the differential tension between the two springs comes into effect.
Ausgehend hiervon liegt der Erfindung die Aufgabe zu¬ grunde, die bekannte Montagevorrichtung dahingehend zu verbessern, daß sie einfacher handhabbar und schneller und zuverlässiger montierbar ist.Proceeding from this, the invention is based on the object of improving the known assembly device in such a way that it is easier to handle and quicker and more reliable to assemble.
Zur Lösung dieser Aufgabe werden die im Patentanspruch 1 angegebenen Merkmale vorgeschlagen. Weitere vorteilhaf¬ te Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To achieve this object, the features specified in claim 1 are proposed. Further advantageous refinements and developments of the invention result from the dependent claims.
Der Erfindung liegt der Gedanke zugrunde, mit Hilfe von durch Federkraft an den Zargenschenkeln festklemmbaren Stützorganen das Befestigen bzw. Lösen der Montagevor¬ richtung an beiden Zargenschenkeln gleichzeitig zu ermöglichen, um damit den Arbeitsablauf beim Einbau der Türzarge zu vereinfachen und zu beschleunigen. Dies wird erfindungsgemäß dadurch erreicht, daß der Klemm¬ körper in seiner einen vorgegebenen Minimalabstand zwischen Klemmflächen und Anlagefläche definierenden Grundstellung unter Einwirkung der Feder gegen .einen Grundanschlag des Stützorgans anliegt, und daß der Klemmkörper mittels des als Druckorgan ausgebildeten Betätigungsorgans entgegen der Federkraft unter Ver¬ größerung des Abstandes zwischen Klemmfläche und Anlage¬ fläche relativ zur Anlagefläche verschiebbar ist. Vor¬ teilhafterweise ist der Klemmkörper mit Hilfe des Druck¬ organs entgegen der Federkraft gegen eine einen Maximal¬ abstand zwischen Klemmfläche und Anlagefläche definie¬ renden, vorzugsweise verstellbaren Endanschlag anschlag¬ bar. Durch den vorgegebenen Minimalabstand kann beim Festklemmen des Stützorgans der Verschiebeweg des Klemm¬ körpers reduziert werden. Der Minimalabstand ist dabei zweckmäßig etwas kleiner als die kleinste in der Praxis vorkommende Zargenwandstärke.The invention is based on the idea of being able to be clamped to the frame legs by spring force Support members to enable the mounting device to be attached or detached to both frame legs at the same time, in order to simplify and accelerate the workflow when installing the door frame. This is achieved according to the invention in that the clamping body, in its basic position defining a predetermined minimum distance between the clamping surfaces and the contact surface, rests against the base stop of the supporting member under the action of the spring, and in that the clamping member by means of the actuating member designed as a pressure member counteracts the spring force against Ver the distance between the clamping surface and the contact surface can be displaced relative to the contact surface. Advantageously, the clamping body can be stopped with the aid of the pressure element against the spring force against a preferably adjustable end stop defining a maximum distance between the clamping surface and the contact surface. The displacement distance of the clamping body can be reduced by the predetermined minimum distance when the support member is clamped. The minimum distance is expediently somewhat smaller than the smallest frame wall thickness that occurs in practice.
Vorteilhafterweise ist der Klemmkörper entgegen, der Federkraft mit Hilfe des Druckkörpers gegen einen einen Maximalabstand zwischen Klemmfläche und Anlagefläche definierenden, vorzugsweise verstellbaren Endanschlag anschlagbar. Wenn dieser Maximalabstand nur geringfügig größer als die Wandstärke der einzubauenden Türzargen eingestellt wird, kann der Verschiebeweg der Klemmkör¬ per beim Festklemmen der Stützorgane und damit auch der hierfür erforderliche Kraftaufwand auf ein Minimum reduziert werden.Advantageously, the clamping body counteracts the spring force with the help of the pressure body against a preferably adjustable end stop that defines a maximum distance between the clamping surface and the contact surface. If this maximum distance is set only slightly larger than the wall thickness of the door frames to be installed, the displacement of the clamping bodies when clamping the support members and thus also the the effort required for this is reduced to a minimum.
Eine bevorzugte Ausgestaltung sieht vor, daß der Klemm¬ körper in einer Führungsausnehmung des Stützorgans vorzugsweise unverdrehbar geführt ist. Um die Montage- vorrichtuπg an unterschiedliche Zargenbreiten anpassen zu können, sind an einem Ausleger des Stützorgans meh¬ rere, in unterschiedlichem Abstand von der Teleskop¬ strebe angeordnete Führungsausnehmungen zum wahlweisen Einsetzen des Klemmkörpers angeordnet.A preferred embodiment provides that the clamping body is preferably non-rotatably guided in a guide recess of the support member. In order to be able to adapt the mounting device to different frame widths, a plurality of guide recesses are arranged on a cantilever of the support member and arranged at different distances from the telescopic strut for the optional insertion of the clamping body.
Zweckmäßig weist der Klemmkörper einen in der Führungs¬ ausnehmung des Stützorgans geführten Führungszapfen und einen am freien Ende des Führungszapfens angeformten, die Klemmfläche aufweisenden, vorzugsweise dünnwandigen Klemmbacken auf. Der Führungszapfen weist dabei vorteil¬ hafterweise einen nach außen über die Anlagefläche überstehenden Zapfenteil auf, der nach innen durch eine den Grundanschlag bildende Anschlagschulter begrenzt ist .The clamping body expediently has a guide pin guided in the guide recess of the support member and a preferably thin-walled clamping jaws formed on the free end of the guide pin and having the clamping surface. The guide pin advantageously has a pin part which projects outwards beyond the contact surface and which is delimited inwards by a stop shoulder forming the basic stop.
Ein Verkanten der Montagevorrichtung gegenüber der von der Türzarge aufgespannten Ebene läßt sich bekannter¬ maßen dadurch verhindern, daß die Stützorgane einen gegenüber der Teleskopstrebe parallel versetzten Kanten¬ anschlag für die Türzarge aufweisen. Der Kantenanschlag ist dabei zweckmäßig am Klemmkörper angeordnet und vorteilhafterweise durch den überstehenden Zapfenteil der Führungszapfen gebildet. Ein Verkanten bzw. Heraus¬ schieben der Türzarge aus der Wandöffnung durch den sich ausdehnenden Montageschaum kann verhindert werden, wenn der Klemmkörper zusätzlich einen stirnseitig über¬ stehenden, zur Klemmfläche senkrechten, gegenüber der Teleskopstrebe parallel versetzten Wandanschlag aufweist Der zum Kantenaπschlag parallele Wandanschläg kann von der Längsachse der Teleskopstrebe einen anderen, vorzugs¬ weise größeren Abstand aufweisen als der Kantenanschlag.Tilting of the assembly device in relation to the plane spanned by the door frame can, as is known, be prevented by the support members having an edge stop for the door frame which is offset parallel to the telescopic strut. The edge stop is expediently arranged on the clamping body and is advantageously formed by the protruding pin part of the guide pin. Tilting or pushing the door frame out of the wall opening through the Expanding assembly foam can be prevented if the clamping body additionally has a wall stop protruding on the end face, perpendicular to the clamping surface and offset parallel to the telescopic strut. The wall stop parallel to the edge stop can have a different, preferably larger, distance from the longitudinal axis of the telescopic strut Edge stop.
Im folgenden wird die Erfindung anhand eines in der Zeichnung schematisch dargestellten Ausführungsbei¬ spiels näher erläutert. Es zeigenThe invention is explained in more detail below on the basis of an exemplary embodiment shown schematically in the drawing. Show it

Der in der Zeichnung dargestellte, als Montagehilfe beim Einbau von Türzargen dienende Türzargenpanner be¬ steht im wesentlichen aus einer in ihrer Länge ver¬ stellbaren Teleskopstrebe 12 und zwei an den stirnsei¬ tigen Enden der Teleskopstrebe 12 angeordneten, an den einander gegenüberliegenden vertikalen Schenkeln der Türzarge lösbar festklemmbaren Stützorganen 14,14'.The door frame tensioner shown in the drawing, which serves as an assembly aid when installing door frames, essentially consists of a telescopic strut 12, which is adjustable in length, and two arranged on the front ends of the telescopic strut 12, on the opposite vertical legs of the door frame releasably clampable support members 14, 14 '.
Die Stützorgane 14,14' weisen jeweils drei sternförmig angeordnete, im rechten Winkel von der Teleskopstrebe abstehende Ausleger 16,16' mit einer in einer gemeinsa¬ men Ebene angeordneten, nach außen weisenden Anlageflä¬ che 18 für die einander zugewandten Innenflächen der nicht dargestellten Zargenschenkel auf. Einer der Aus¬ leger 16' ist jeweils länger ausgebildet und mit drei Führungsausneh ungen 20, 20' , 20' ' zur Aufnahme eines Klemmkörpers 22 versehen, mit dem das Stützorgan 14,14' am Zargenschenkel lösbar festklemmbar ist.The support members 14, 14 'each have three star-shaped, at right angles from the telescopic strut protruding arms 16, 16 'with an outwardly facing contact surface 18 arranged in a common plane for the mutually facing inner surfaces of the frame legs, not shown. One of the cantilevers 16 'is each longer and provided with three guide recesses 20, 20', 20 '' for receiving a clamping body 22 with which the support member 14, 14 'can be releasably clamped to the frame leg.
Der entgegen der Kraft einer Feder 23 verschiebbar in der Fuhrungsausnehmung 20 gelagerte Klemmkörper 22 besteht im wesentlichen aus einem parallel zur Längs¬ achse 25 der Teleskopstrebe 12 verschiebbar geführten, nach außen über die Anlagefläche 18 überstehenden Füh¬ rungszapfen 24, einem am freien Ende des Führungszap¬ fens 24 angeformten dünnwandigen Klemmbacken 26 mit einer der Anlagefläche 18 zugewandten Klemmfläche 28, sowie einem stirnseitig über den Klemmbacken 26 über¬ stehenden, parallel zur Teleskopstrebe 12 ausgerichte¬ ten Wandanschlag 30. Der im Querschnitt kreissegment- förmige Führungszapfen 24 durchsetzt auf der der Anlage¬ fläche 18 zugewandten Seite der Fuhrungsausnehmung 20 eine Durchtrittsöffnung 27 mit entsprechendem Quer¬ schnitt, so daß ein Verdrehen des Führungszapfens 24 in der Fuhrungsausnehmung 20 nicht möglich ist. Der in der Grundstellung (Fig. 4) nach außen über die Anlagefläche 18 überstehende Teil durch eine Aπschlagschulter 44 begrenzte Teil 29 des Führungszapfens 24 bildet einen parallel zur Teleskopstrebe 12 ausgerichteten Kantenan¬ schlag für die schmale Läπgsseitenflache der Türzarge. Gegenüber der Längsachse 25 der Teleskopstrebe 12 weist der Kantenanschlag 29 einen geringeren Abstand auf als der Wandanschlag 30.The clamping body 22, which is displaceably mounted in the guide recess 20 against the force of a spring 23, essentially consists of a guide pin 24, which is guided parallel to the longitudinal axis 25 of the telescopic strut 12 and projects outwards beyond the contact surface 18, one at the free end of the guide pin ¬ fens 24 molded thin-walled clamping jaws 26 with a clamping surface 28 facing the contact surface 18, and a wall stop 30 protruding on the end face above the clamping jaws 26 and aligned parallel to the telescopic strut 12 ¬ surface 18 facing side of the guide recess 20, a passage opening 27 with a corresponding cross-section, so that a rotation of the guide pin 24 in the guide recess 20 is not possible. The part 29 of the guide pin 24, which in the basic position (FIG. 4) projects beyond the contact surface 18 and is delimited by an abutment shoulder 44, forms an edge stop for the narrow longitudinal side surface of the door frame which is aligned parallel to the telescopic strut 12. Facing the longitudinal axis 25 of the telescopic strut 12 the edge stop 29 has a smaller distance than the wall stop 30.
An seinem inneren, freien Ende weist der Führungszapfen 24 eine zur Innenseite des Auslegers 16' hin offene Gewiπdebohrung 32 auf, in welche der Gewindeschaft 34 eines als Druckorgan in Form einer Sterngriffschraube 36 ausgebildeten Betätigungsorgans 36 eingedreht ist. Die als Druckfeder ausgebildete, unter Vorspannung stehende Feder 23 stützt sich gegen eine Schulter 38 des Betätigungsorgans 36 sowie gegen eine Schulter.40 der Fuhrungsausnehmung 20 ab. In der Grundstellung wird der von der Feder 23 nach innen gedrückte Klemmkörper 22 durch die am Führungszapfen 24 angeformte, gegen die Anlagefläche 18 anliegenden Anschlagschulter 44 in einer Lage gehalten, in der die Klemmfläche 28 des Klemmbackens 26 einen vorgegebenen Minimalabstaπd von der Anlagefläche 18 aufweist.At its inner, free end, the guide pin 24 has a threaded bore 32 which is open toward the inside of the arm 16 'and into which the threaded shaft 34 of an actuating member 36 designed as a pressure element in the form of a star grip screw 36 is screwed. The spring 23, which is designed as a compression spring and is pretensioned, is supported against a shoulder 38 of the actuating member 36 and against a shoulder . 40 of the guide recess 20. In the basic position, the clamping body 22 pressed inward by the spring 23 is held in a position by the stop shoulder 44 formed on the guide pin 24 and abutting against the contact surface 18, in which the clamping surface 28 of the clamping jaw 26 has a predetermined minimum distance from the contact surface 18.
Zum Aufsetzen der Stützorgane 14,14' auf die Zargen¬ schenkel werden die Klemmkörper 22 zunächst durch Ein¬ drücken der Betätigungsorgane 36 entgegen der Kraft der Druckfedern 23 unter Vergrößerung der zwischen Anla¬ gefläche 18 und Klemmfläche 28 eingeschlossenen Klemm¬ spalte verschoben, bis die - Schultern 38 der Betätigungs¬ organe 36 gegen den von einer Ringschulter 46 der Fuh¬ rungsausnehmung 20 gebildeten Endanschlag anschlagen. Anschließend werden die Klemmbacken 26 beider Stützor¬ gane 14,14' gleichzeitig bis zum Anschlag der Zargen¬ schenkel an den Kantenanschlägen 29 in den Spalt zwi¬ schen der Maueröffnung und den Zargenscheπkeln einge- führt. Nach Entlastung der Betätigungsorgane werden die Zargenschenkel dann durch die Federkraft zwischen der Anlagefläche 18 und der Klemmfläche 28 festgeklemmt.To place the support members 14, 14 'on the frame legs, the clamping bodies 22 are first displaced by pressing in the actuating members 36 against the force of the compression springs 23 and increasing the clamping gaps enclosed between the contact surface 18 and the clamping surface 28 until the - Strike the shoulders 38 of the actuating members 36 against the end stop formed by an annular shoulder 46 of the guide recess 20. Subsequently, the clamping jaws 26 of both support organs 14, 14 'are simultaneously inserted into the gap between the wall opening and the frame legs until the frame legs stop at the edge stops 29. leads. After relieving the actuators, the frame legs are then clamped by the spring force between the contact surface 18 and the clamping surface 28.
Durch Verdrehen der Betätigungsorgane 36 kann der Ver¬ schiebeweg des Klemmkörpers 22 verlängert bzw. verkürzt und damit an unterschiedliche Türzargenwandstärken angepaßt werden.By turning the actuating members 36, the displacement of the clamping body 22 can be lengthened or shortened and thus adapted to different door frame wall thicknesses.
Die zwischen den Stützorganen 14,14' angeordnete Tele¬ skopstrebe 12 besteht aus einem mit dem Stützorgan 14 starr verbundenen, als Vierkantrohr ausgebildeten Tele¬ skoprohr 52, in welchem die al.s Vierkantrohr ausgebil¬ dete, mit dem Stützorgan 14' verbundene Teleskopstange 54 gleitend längsverschiebbar gelagert ist. Die Tele¬ skopstange 54 läßt sich mit Hilfe einer in eine Gewin¬ debohrung der verstärkten Teleskoprohrwand eingedrehten Klemmschraube 56 in beliebigen Verschiebestellungen arretieren. Eine auf der Teleskopstange 54 angeordnete, nicht dargestellte Längenskala zeigt beim Ablesen der am offenen Ende des Teleskoprohrs 52 sichtbaren Markie¬ rung den genauen Abstand zwischen den beiden Anlageflä¬ chen 18 an.The telescopic strut 12 arranged between the supporting members 14, 14 'consists of a telescopic tube 52 which is rigidly connected to the supporting member 14 and is designed as a square tube and in which the al. Square tube designed and connected to the supporting member 14' is connected to the telescopic rod 54 is slidably mounted longitudinally. The telescopic rod 54 can be locked in any displacement positions with the aid of a clamping screw 56 screwed into a threaded bore of the reinforced telescopic tube wall. A length scale, not shown, arranged on the telescopic rod 54 shows the exact distance between the two contact surfaces 18 when the marking visible at the open end of the telescopic tube 52 is read.
Zusammenfassend ist folgendes festzustellen: Die Erfin¬ dung bezieht sich auf eine Montagehilfe, die beim Ein¬ bau von Türzargen in einer Wandöffnung Verwendung fin¬ det. Die Montagehilfe 10 weist eine auf den lichten Abstand zwischen den zwei einander gegenüberliegenden vertikalen Zargenschenkeln einstellbare Teleskopstrebe 12 und zwei an den stirnseitigen Enden der Teleskop- strebe 12 angeordnete, an je einem der vertikalen Zar¬ genschenkel lösbar festklemmbare Stützorgane 14,14' auf, welche sich mit stirnseitig nach außen weisenden Anlageflächen 18 gegen die einander zugewandten Innen¬ flächen der Zargenschenkel abstützen. Um ein einfaches und schnelles Festklemmen beider Stützorgane 14,14' zu gewährleisten, ist an den Stützorganen 14,14' je ein entgegen der Kraft einer Feder 23 relativ zur Anlage¬ fläche 18 bewegbarer, unter der Einwirkung der Feder 23 mit einer Klemmfläche 28 gegen eine der Innenfläche abgewandte Außenfläche des betreffenden Zargenschenkels anpreßbarer Klemmkörper 22 angeordnet. In summary, the following can be stated: The invention relates to an assembly aid which is used in the installation of door frames in a wall opening. The assembly aid 10 has a telescopic strut 12 that can be adjusted to the clear distance between the two mutually opposite vertical frame legs and two at the front ends of the telescopic strut 12 arranged on each of the vertical frame legs releasably clampable support members 14, 14 ', which are supported with outwardly facing end faces 18 against the mutually facing inner surfaces of the frame legs. In order to ensure that the two support members 14, 14 'can be clamped easily and quickly, one each can be moved on the support members 14, 14' against the force of a spring 23 relative to the contact surface 18 and under the action of the spring 23 with a clamping surface 28 an outer surface of the relevant frame leg that can be pressed against the inner surface and that is capable of pressing on the clamping body 22.
