Description

Die Erfindung betrifft eine Zwingenanordnung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a clamp arrangement according to the preamble of patent claim 1.

Eine derartige Anordnung ist bekannt aus dem DE-U 8702 315. Dort ist eine Anordnung mit zwei verstellbaren Klemmbacken vorgesehen, welche an der Oberkante bzw. der Unterkante eines Möbelstücks festgeklemmt werden können. Hierzu ist die eine Klemmbacke mit einer Spindelmutter versehen, und eine Stellspindel ist vorgesehen, mittels deren die Lage der anderen Klemmbacke verstellt werden kann. An der einen Klemmbacke ist höhenverstellbar ein Rohr befestigt, an welchem über verschwenkbare Arme eine Beistellplatte befestigt ist.Such an arrangement is known from DE-U 8702 315. An arrangement with two adjustable clamping jaws is provided there, which can be clamped on the upper edge or the lower edge of a piece of furniture. For this purpose, the one jaw is provided with a spindle nut, and an adjusting spindle is provided, by means of which the position of the other jaw can be adjusted. On one clamping jaw, a tube is attached in a height-adjustable manner, to which a side plate is attached via pivotable arms.

Es handelt sich hier um eine aufwendige Anordnung, die relativ viel Platz einnimmt und ästhetisch wenig befriedigt. Deshalb ist es eine Aufgabe der Erfindung, hier eine Verbesserung zu schaffen.It is a complex arrangement that takes up a lot of space and is aesthetically unsatisfactory. It is therefore an object of the invention to provide an improvement here.

Nach der Erfindung wird diese Aufgabe gelöst durch die im Anspruch 1 angegebenen Maßnahmen. Man erhält so eine äußerst kompakte und formschöne Zwingenanordnung, die bei entsprechender Ausgestaltung sehr belastbar ist.According to the invention, this object is achieved by the measures specified in claim 1. In this way, an extremely compact and shapely clamp arrangement is obtained which, with the appropriate design, is very resilient.

Mit besonderem Vorteil geht man dabei nach Anspruch 2 vor, da man in diesem Fall zur Anbringung oder zur Demontage der Zwingenanordnung kein Werkzeug benötigt, sondern die Arbeitsvorgänge von Hand ausführen kann.It is particularly advantageous to proceed according to claim 2, since in this case no tools are required for attaching or removing the clamp arrangement, but the operations can be carried out by hand.

In sehr vorteilhafter Weise wird die Zwingenanordnung ferner gemäß Anspruch 5 weitergebildet, wobei die Hülse zweckmäßig gemäß Anspruch 6 gegen axiale Verschiebungen gesichert wird.In a very advantageous manner, the clamp arrangement is further developed according to claim 5, the sleeve being expediently secured against axial displacement according to claim 6.

Eine sehr variable Anordnung ergibt sich ferner durch die Merkmale der Ansprüche 10 und 11. Dies erlaubt eine Verstellung des Gegenstücks, das z. B. einen Bildschirm tragen kann, in sehr weiten Grenzen, wobei eine leichte Beweglichkeit durch die Merkmale des Anspruchs 12 sichergestellt wird.A very variable arrangement also results from the features of the claims 10 and 11. This allows an adjustment of the counterpart, the z. B. can carry a screen, within very wide limits, easy mobility is ensured by the features of claim 12.

Die Begriffe oben, unten, links und rechts beziehen sich im folgenden jeweils auf die Darstellung in der Zeichnung bzw. auf die normale Arbeitsstellung der Zwingenanordnung, wenn sie z.B. an einer Tischplatte montiert ist.The terms above, below, left and right each refer to the representation in the drawing or to the normal working position of the clamp arrangement if they e.g. is mounted on a table top.

Fig. 1 zeigt eine erfindungsgemäße Zwingenanordnung 10, die hier an einer Platte 11 befestigt dargestellt ist. Die Platte 11 kann z.B. die Tischplatte eines im übrigen nicht dargestellten Tisches sein. Sie hat an ihrem Außenrand bei diesem Beispiel eine Abschrägung 12.Fig. 1 shows a clamp assembly 10 according to the invention, which is shown attached to a plate 11. The plate 11 can e.g. the table top of a table, not otherwise shown. In this example, it has a bevel 12 on its outer edge.

Die Zwingenanordnung 10 hat ein an die Querschnittsform der Platte 11 angepaßtes Zwingen-Formstück 13, das etwa die Form eines langgestreckten C hat und auf seiner Unterseite 14 in beiden Richtungen mit einer Verbreiterung 15, 15' versehen ist, um eine gute Stabilität in seitlicher Richtung zu erzielen und den Druck auf eine große Fläche zu verteilen.The clamp arrangement 10 has a clamp fitting 13 which is adapted to the cross-sectional shape of the plate 11 and which has approximately the shape of an elongated C and is provided on its underside 14 with a broadening 15, 15 'in both directions in order to provide good lateral stability to achieve and distribute the pressure over a large area.

An seiner Oberseite 18 hat das Formstück 13 eine Erhebung 20, die mit einer Gewindebohrung 22 versehen ist, welche nach unten in eine im Querschnitt trapezförmige Ausnehmung 24 größeren Durchmessers übergeht.On its upper side 18, the shaped piece 13 has an elevation 20 which is provided with a threaded bore 22 which merges downwards into a recess 24 of larger diameter which is trapezoidal in cross section.

In der trapezförmigen Ausnehmung 24 befindet sich eine an deren Form angepaßte Klemmbacke 26, die auch als Anpreßteil bezeichnet werden kann und welche mittels einer nur schematisch angedeuteten Schraube 28 mit einem Gewindeabschnitt 30 verbunden ist, der einstückig mit einem zylindrischen Abschnitt 32 ausgebildet ist, welcher z.B. einen Durchmesser von 30 mm und eine Länge von etwa 100 mm haben kann. Der zylindrische Abschnitt 32, sowie der Gewindeabschnitt 30, können z.B. aus Messing oder aus einem formstabilen Kunststoff ausgebildet sein. Der Gewindeabschnitt 30 ist mit seinem Außengewinde 34 in der Gewindebohrung 22 des Formstücks 13 geführt und kann aus dieser herausgeschraubt werden, um die Zwingenanordnung 10 von der Platte 11 zu lösen, oder in diese hineingeschraubt werden, um die Klemmbacke 26 gegen die Platte 11 zu pressen und dadurch die Zwingenanordnung 10 an der Platte 11 zu befestigen. Dabei ist sehr vorteilhaft, daß der zylindrische Abschnitt 32 "handgerecht" ausgebildet ist, d.h. man kann ihn mit der geschlossenen Faust packen und leicht das erforderliche Drehmoment auf ihn übertragen, ohne daß man dazu irgendwelche Werkzeuge benötigt.In the trapezoidal recess 24 there is a jaw 26 adapted to its shape, which can also be referred to as a pressing part and which is connected by means of a screw 28, which is only indicated schematically, to a threaded section 30 which is integrally formed with a cylindrical section 32, which, for example can have a diameter of 30 mm and a length of about 100 mm. The cylindrical section 32, as well as the threaded section 30, can be formed, for example, from brass or from a dimensionally stable plastic. The threaded section 30 is guided with its external thread 34 in the threaded bore 22 of the shaped piece 13 and can be screwed out of this in order to detach the clamp arrangement 10 from the plate 11, or screwed into it in order to press the clamping jaw 26 against the plate 11 and thereby secure the clamp assembly 10 to the plate 11. It is very advantageous that the cylindrical portion 32 is "hand-made", ie you can grab it with your closed fist and easily transfer the required torque to it without the need for any tools.

Nach der Befestigung der Zwingenanordnung 10 an der Platte 11 wird über den zylindrischen Abschnitt 32 eine Hülse 36 gestülpt, welche den Abschnitt 32 mit leichtem Spiel umgibt, so daß sie auf ihm gedreht werden kann. Der zylindrische Abschnitt 32 hat eine Ringnut 38; ihr gegenüberliegend befindet sich in der Hülse 36 eine Gewindebohrung 40, in die eine (nicht dargestellte) Schraube geschraubt werden kann, deren Ende in die Ringnut 38 ragt und dadurch die Hülse 36 als Eingriffsglied gegen axiale Bewegungen sichert.After fastening the clamp assembly 10 to the plate 11, a sleeve 36 is placed over the cylindrical section 32, which surrounds the section 32 with a slight play so that it can be rotated on it. The cylindrical section 32 has an annular groove 38; opposite is located in the sleeve 36, a threaded bore 40 into which a screw (not shown) can be screwed, the end of which protrudes into the annular groove 38 and thereby secures the sleeve 36 as an engagement member against axial movements.

Mit dem oberen Ende der Hülse 36 ist bei 42 exzentrisch ein Trägerteil in Form einer kreisrunden Schreibe 44 verbunden, deren Form aus den Fig. 1 und 4 klar hervorgeht.With the upper end of the sleeve 36, a support part in the form of a circular disc 44 is connected eccentrically at 42, the shape of which can be clearly seen from FIGS. 1 and 4.

Auf der in Fig. 1 oberen Seite der Scheibe 44 - diese Seite ist in Fig. 4 dargestellt - sind zwei flache Kreisringe 46 und 48 aus einem Kunststoff mit niedrigem Reibungskoeffizienten befestigt, z.B. aus Delrin. Auf diesen Ringen 46, 48 gleitet ein Gegenstück zum Trägerteil 44, hier ebenfalls in Form einer kreisrunden Scheibe 50. Die Scheiben 44 und 50 sowie die Hülse 36 sind bevorzugt aus Stahl hergestellt. Mittels schematisch angedeuteter Schrauben 54, 56 ist an der Scheibe 50 ein Abstütz- bzw. Beistellbrett 58 befestigt, auf das z.B. der (nicht dargestellte) Bildschirm eines Computers gestellt werden kann. Die beiden Scheiben 44 und 50 sind im Bereich ihrer gemeinsamen Drehachse 60 mittels einer Schraube 62 drehbar miteinander verbunden. Die Drehachse 60 hat einen Abstand a von der Drehachse 64 der Hülse 36.On the upper side of the disk 44 in FIG. 1 - this side is shown in FIG. 4 - two flat circular rings 46 and 48 made of a plastic with a low coefficient of friction are fastened, e.g. from Delrin. A counterpart to the carrier part 44 slides on these rings 46, 48, here also in the form of a circular disk 50. The disks 44 and 50 and the sleeve 36 are preferably made of steel. By means of schematically indicated screws 54, 56, a support or side board 58 is attached to the disk 50, on which e.g. the computer screen (not shown) can be set. The two disks 44 and 50 are rotatably connected to one another in the region of their common axis of rotation 60 by means of a screw 62. The axis of rotation 60 is at a distance a from the axis of rotation 64 of the sleeve 36.

Durch diese Exzentrizität der beiden Drehachsen 60 und 64 ergeben sich für das Stützbrett 58 weite Verstellmöglichkeiten, wozu auf die Fig. 5 bis 7 verwiesen wird. Gleiche oder gleichwirkende Teile wie in den vorhergehenden Figuren werden auch in den nachfolgenden Figuren mit denselben Bezugszeichen bezeichnet und gewöhnlich nicht nochmals beschrieben.This eccentricity of the two axes of rotation 60 and 64 results in wide adjustment possibilities for the support board 58, for which reference is made to FIGS. 5 to 7. Parts that are the same or have the same effect as in the previous figures are also designated with the same reference symbols in the subsequent figures and are usually not described again.

Aus Fig. 5 erkennt man, daß die Stützplatte 58 relativ zum Tisch 11 in der hier dargestellten Richtung um den Weg 2a verschoben werden kann, und zwar längs einer Kreisbahn 68. Die neue Lage der Stützplatte 58 wird dann mit 58' bezeichnet, die verschobene Lage der Drehachse 60 mit 60', und die verschobene Lage der Scheibe 50 mit 50'.From Fig. 5 it can be seen that the support plate 58 can be displaced relative to the table 11 in the direction shown here by the path 2a, namely along a circular path 68. The new position of the support plate 58 is then designated 58 ', the displaced Position of the axis of rotation 60 with 60 ', and the shifted position of the disc 50 with 50'.

Fig. 6 zeigt, daß die Stützplatte 58 bei dieser Translationsbewegung zusätzlich auch noch verdreht werden kann, wobei die verschiedenen dargestellten Stellungen mit 58'', 58‴ und 58'''' bezeichnet sind. Dies gibt einen guten Eindruck von den Verstellmöglichkeiten.FIG. 6 shows that the support plate 58 can also be rotated during this translational movement, the various positions shown being designated 58 ″, 58 ‴ and 58 ″ ″. This gives a good impression of the adjustment options.

Fig. 7 zeigt eine längliche Stützplatte 70, die an zwei Zwingenanordnungen 10 und 10' abgestützt ist, und zwar bei diesem Beispiel in einem Abstand von etwa 11a, wobei a der Angabe in Fig. 1 entspricht. Die Stützplatte 70 ist also an der oberen Scheibe 50 beider Zwingenanordnungen 10 und 10' befestigt, wobei die Ruhelage dieser beiden Scheiben in Fig. 7 mit A und B bezeichnet ist und der voll ausgezogenen Lage der Stützplatte 70 entspricht.FIG. 7 shows an elongated support plate 70 which is supported on two clamp arrangements 10 and 10 ', in this example at a distance of approximately 11a, where a corresponds to the information in FIG. 1. The support plate 70 is therefore fastened to the upper plate 50 of both clamp arrangements 10 and 10 ', the rest position of these two plates being designated A and B in FIG. 7 and corresponding to the fully extended position of the support plate 70.

Auch hier ist eine Parallelverschiebung um den Abstand 2a in die Lage 70' möglich, oder z.B. eine Verschiebung nur des linken Abschnitts nach hinten, während der rechte vorne bleibt, wobei sich dann bei der rechten Zwingenanordnung 10' der Mittelpunkt 60 um den Winkel alpha von z.B. 30° in die Stellung 60'' bezüglich der Drehachse 64 verdreht. In diesem Fall nimmt die Stützplatte die Lage 70'' ein. Eine solch breite Stützplatte 70 ist ideal für datenverarbeitende Geräte, z.B. für große Monitore für CAD-Anwendungen. Da sie von zwei Zwingenanordnungen 10 und 10' abgestützt wird, hat sie eine große Tragkraft.A parallel displacement by the distance 2a into the position 70 'is also possible here, or e.g. a displacement of only the left section to the rear while the right section remains in front, in which case the center 60 in the right clamp arrangement 10 'then moves by the angle alpha of e.g. Twisted 30 ° in the position 60 '' with respect to the axis of rotation 64. In this case, the support plate takes up the position 70 ″. Such a wide support plate 70 is ideal for data processing devices, e.g. for large monitors for CAD applications. Since it is supported by two clamp arrangements 10 and 10 ', it has a large load capacity.

Fig. 8 zeigt eine Variante, bei welcher eine längere Hülse 36' verwendet und auf den zylindrischen Abschnitt 32 aufgebracht wird.8 shows a variant in which a longer sleeve 36 ′ is used and is applied to the cylindrical section 32.

An dieser Hülse 36' ist seitlich eine Klemmschraube 76 angebracht, mittels deren ein Stützrohr 78 in Höhenrichtung in der Hülse 36' verstellt und dort in der gewünschten Stellung festgeklemmt werden kann. Das Stützrohr 78 ist seinerseits mit dem Fuß 80 einer Stützplatte 82 verbunden, auf der ein Rednerpult 84 beispielsweise unter 30° befestigt sein kann.A clamping screw 76 is attached to the side of this sleeve 36 ', by means of which a support tube 78 can be adjusted vertically in the sleeve 36' and clamped there in the desired position. The support tube 78 is in turn connected to the foot 80 of a support plate 82 on which a lectern 84 is attached, for example at 30 ° can be.

Ein solches Redner- oder Stehpult kann leicht an einem Tisch oder Schreibtisch befestigt und anschließend wieder abgenommen werden, wenn es nicht mehr benötigt wird. Dabei ergibt sich ein modularer Aufbau, d.h. die Zwingenanordnung 10 kann z.B. mit einem Rednerpult oder Stehpult (Fig. 8) oder mit einer Stützplatte (Fig. 1 bis 4), oder mit einem Telefontablar, einer Halterung für eine Tischleuchte, einer Halterung für eine Briefablage, etc. verbunden werden, oder mit einem sonstigen Gerät, je nach den Bedürfnissen des Augenblicks. Dabei kommt, wenn die Zwingenanordnung mit einer Halterung kombiniert wird, der Lagerung mittels einer Scheibenanordnung selbständige Bedeutung zu, da sie sich in der Praxis als außerordentlich vorteilhaft erweist.Such a lectern or standing desk can easily be attached to a table or desk and then removed again when it is no longer needed. This results in a modular structure, i.e. the clamp assembly 10 may e.g. with a lectern or standing desk (Fig. 8) or with a support plate (Fig. 1 to 4), or with a telephone shelf, a holder for a table lamp, a holder for a letter tray, etc., or with another device, depending on the needs of the moment. When the clamp arrangement is combined with a holder, storage by means of a disc arrangement is of independent importance since it proves to be extremely advantageous in practice.

Claims (13)

  1. Clamp arrangement for fixing to an element of a piece of furniture, in particular to the top (11) of a table or of a cupboard, with a shaped piece (13) gripping around the element and a threaded part (30) provided with a pressure part (26) and guided in a thread (22) of the shaped piece (13), characterised in that the threaded part (30) is disposed on the upper side of the shaped piece (13) and exhibits an essentially cylindrical projection (32) protruding upwards, and in that an element (36) which carries an implement is disposed rotatably on this cylindrical projection (32).
  2. Clamp arrangement according to claim 1, characterised in that the essentially cylindrical projection (32) exhibits a handy diameter, e.g. of the order of magnitude of 20 to 50 mm and preferably about 30 mm, in order to be able to transmit an adequate torque to it manually.
  3. Clamp arrangement according to claim 1 or 2, characterised in that the shaped piece (13) gripping around the element (11) of the piece of furniture is adapted to the cross-sectional shape of this element (11).
  4. Clamp arrangement according to any preceding claim, characterised in that on its side opposite the threaded part (30) the shaped piece (13) is provided with an enlargement (15, 15') adapted to rest against the underside of the element (11) of the piece of furniture when in use.
  5. Clamp arrangement according to any preceding claim, characterised in that the pivotably disposed element is embodied as a sleeve (36) engaging over the essentially cylindrical projection (32).
  6. Clamp arrangement according to claim 5, characterised in that the essentially cylindrical projection (32) is provided with an annular groove (38), and in that an engaging element (40), in particular a screw, is associated with said sleeve (36) for engagement in this annular groove (38).
  7. Clamp arrangement according to any preceding claim, characterised in that the implement is embodied as a lectern (84) (Fig. 8).
  8. Clamp arrangement according to any preceding claim, characterised in that the implement is embodied as a carrier part (44, 58).
  9. Clamp arrangement according to claims 5 and 8, characterised in that the sleeve (36) is connected to the carrier part (44).
  10. Clamp arrangement according to claim 9, characterised in that the carrier part (44) is connected rotatably to a counterpart (50), and in that the axis of rotation (60) of these two parts (44, 50) is different to the axis of rotation (64) of the sleeve (36).
  11. Clamp arrangement according to claim 10, characterised in that at least one planar sliding bearing element (46, 48) is provided between the carrier part (44) and the counterpart (50).
  12. Clamp arrangement according to claim 11, characterised in that the at least one planar sliding bearing element (46, 48) is embodied as a circular ring-shaped plastic part made of a slideable plastic.
  13. Clamp arrangement according to any of claims 1 to 6, characterised in that the implement is embodied as a stand, telephone stand, fixture for a table lamp or container for correspondence/documents.
