Abstract

Auxiliary tool for mutual clamping of two plates 7, 8 which butt together with their edges 9, 10, in particular when adhesively bonding the plates to produce a composite plate for interior furnishings. Such a composite plate is suitable, for example, as a worktop for fitted kitchens or as a wall panel. A particularly easy and reliable clamping of the plates against one another, in particular when the edges 9, 10 are to be glued together, is achieved by the fact that adhesion elements 2, 3, each designed as vacuum adhesion devices, are connected by means of a clamping device 6, 17, 19 so as to be displaceable towards one another. The vacuum adhesion devices adhere to the surface 11, 12 of the plates. <IMAGE>

Description

Die Erfindung betrifft ein Hilfswerkzeug zum gegenseitigen Ver­spannen von zwei mit ihren Kanten aneinanderstoßenden Platten, insbesondere beim Verkleben der Platten zur Herstellung eines plattenverbunds für Inneneinrichtungen, wie er z.B. für Einbau­küchen-Arbeitsplatten oder für Wandpaneele benötigt wird.The invention relates to an auxiliary tool for mutually bracing two panels abutting one another with their edges, in particular when gluing the panels to produce a composite panel for interior fittings, as described e.g. for fitted kitchen worktops or for wall panels.

Arbeitsplatten für Einbauküchen sollen möglichst ununter­brochen durchgehende Oberflächen haben. Dies ist nicht nur aus optischen Gründen erwünscht, sondern vor allem, weil jede Art von Fugen zur Verschmutzung und zum Eindringen von Feuchtigkeit führen könnte. Sie werden deswegen über­wiegend aus langen, vorproduzierten Stücken hergestellt, die individuell an die Verhältnisse in der jeweiligen Küche angepaßt werden. Dieses Verfahren ist jedoch auf­wendig, weil ein Großteil des Zuschnitts erst an Ort und Stelle durchgeführt werden kann. Damit sind Lärm und Schmutz verbunden. Das gleiche gilt sinngemäß auch z.B. für Wandpaneele in Duschkabinen, Badezimmern usw.Worktops for fitted kitchens should have continuous surfaces as continuously as possible. This is desirable not only for optical reasons, but above all because any type of joint could lead to contamination and moisture penetration. Therefore, they are mainly made from long, pre-produced pieces, which are individually adapted to the conditions in the respective kitchen. However, this process is complex because a large part of the cutting can only be carried out on the spot. This is associated with noise and dirt. The same applies analogously to wall panels in shower cubicles, bathrooms, etc.

Soweit bisher in einzelnen Fällen Arbeitsplatten für Ein­bauküchen an ihren Kanten aneinanderstoßend miteinander verklebt wurden, war auch hier der Aufwand erheblich. Ins­besondere war es schwierig, die aneinanderstoßenden Plat­ten während der Abbindezeit des Klebstoffs gegeneinander zu verspannen. Üblicherweise wurden hierzu im Schreiner­handwerk vielfach verwendete Hilfswerkzeuge eingesetzt,wie Zwingen, Keile oder Spannhölzer. Gelegentlich wurden auch von der Unterseite der Arbeitsplatte her Leisten oder dgl. eingeschraubt, um die Platten vorübergehend zu fixieren.As far as worktops for fitted kitchens have been glued together at their edges in individual cases, the effort was also considerable here. In particular, it was difficult to clamp the abutting plates against each other during the setting time of the adhesive. Auxiliary tools, such as clamps, wedges or tensioning sticks, are commonly used for this purpose in the carpentry trade. Occasionally, strips or the like were screwed in from the underside of the worktop in order to temporarily fix the plates.

Hiervon ausgehend liegt der Erfindung die Aufgabenstellung zugrunde, eine Möglichkeit zu schaffen, zwei mit ihren Kan­ten aneinanderstoßende Platten erheblich einfacher und doch zuverlässig gegeneinander zu verspannen.Proceeding from this, the object of the invention is to create a possibility of bracing two plates abutting one another with their edges considerably easier and yet reliably against one another.

Dies wird bei einem Hilfswerkzeug der eingangs bezeichneten Art dadurch erreicht, daß zwei Halteelemente, die jeweils an einer der Platten befestigbar sind, mittels einer Spann­vorrichtung gegeneinander verschiebbar verbunden und die Halteelemente als Vakuumhaftvorrichtungen ausgebildet sind, die auf der Oberfläche der Platten haften.This is achieved in an auxiliary tool of the type described in the introduction in that two holding elements, each of which can be fastened to one of the plates, are displaceably connected to one another by means of a tensioning device and the holding elements are designed as vacuum holding devices which adhere to the surface of the plates.

Im Rahmen der vorliegenden Erfindung wurde gefunden, daß vakuumhaftvorrichtungen, wie sie für andere Anwendungs­ zwecke, beispielsweise für den Transport und das Einset­zen von Glasscheiben, vorbekannt sind, sich hervorragend für den erfindungsgemäßen Zweck eignen, wenn man sie mit einer möglichst fein verstellbaren Spann­vorrichtung verbindet. Die Haltekraft der Vakuumhaftvor­richtungen auf einer glatten Arbeitsplattenoberfläche hat sich als ausreichend erwiesen, obwohl die Kräfte bei der erfindungsgemäßen Verwendung nicht, wie sonst üblich, über­wiegend senkrecht zur Haftfläche, sondern parallel zu dieser, angreifen. Die Haftvorrichtungen beginnen erst auf der Oberfläche zu rutschen, wenn verhältnismäßig große Kräfte angewendet werden. Dies ist im Rahmen der vorliegenden Er­findung häufig sogar als Vorteil anzusehen, weil dadurch ver­hindert wird, daß die Arbeitsflächenkanten übermäßig stark gegeneinandergedrückt werden.In the context of the present invention, it has been found that vacuum holding devices such as those used for other applications purposes, for example for the transport and insertion of glass panes, are well known, are outstandingly suitable for the purpose according to the invention if they are connected with a tensioning device which is as finely adjustable as possible. The holding force of the vacuum adhesive devices on a smooth worktop surface has proven to be sufficient, although the forces in the use according to the invention do not act predominantly perpendicularly to the adhesive surface, but rather parallel to it, as is otherwise customary. The adhesive devices only begin to slide on the surface when relatively large forces are applied. In the context of the present invention, this is often even to be regarded as an advantage because it prevents the work surface edges from being pressed against one another excessively.

Die Spannvorrichtung kann in verschiedener Weise gestaltet und an den Vakuumhaftvorrichten befestigt sein. Wichtig ist dabei, daß sie eine fein einstellbare Verschiebung der Va­kuumhaftvorrichtungen gegeneinander erlaubt und die Kräfte derart an den Vakuumhaftvorrichtungen angreifen, daß kein zu großes Kippmoment auf diese ausgeübt wird, durch das sie von der Oberfläche abgehoben werden könnten.The tensioning device can be designed in various ways and attached to the vacuum holding devices. It is important that it allows a finely adjustable displacement of the vacuum holding devices against one another and that the forces act on the vacuum holding devices in such a way that they do not exert a too large tilting moment, by which they could be lifted off the surface.

Beispielsweise kann die Spannvorrichtung als Spanndraht ausgebildet sein, der jeweils an einer am Umfang der Vakuum­haftvorrichtung befestigten Öse befestigt ist. Seine Länge kann dabei durch verschiedene bekannte Mittel, im einfach­sten Fall durch einen in einen Doppeldraht einsteckbaren Knebel fein verändert werden.For example, the tensioning device can be designed as a tension wire, which is fastened to an eyelet attached to the circumference of the vacuum holding device. Its length can be finely changed by various known means, in the simplest case by a toggle that can be inserted into a double wire.

Die Spannvorrichtung kann auch als Exzentervorrichtung ausge­bildet sein, durch die die Halteelemente gegeneinander ver­schiebbar verbunden sind. Eine andere Alternative ist eine Zahnstange mit einem Zahnradantrieb.The tensioning device can also be designed as an eccentric device, by means of which the holding elements are connected to one another so as to be displaceable. Another alternative is one Rack with a gear drive.

Vorzugsweise sind an den Vakuumhaftvorrichtungen Tragteile für die Spannvorrichtung befestigt, die im Regel­fall einige Zentimeter von diesen hervorstehen. In diesem fall werden unzulässige Kippmomente dadurch vermieden, daß die Spannvorrichtung selbst in sich biegesteif ist (bei­spielsweise ein längenveränderlicher Stab oder Profilkörper) und daß sie derartig starr an den Tragteilen befestigt ist, daß sie parallel zur Haftfläche angreift. Dadurch wirken die Spannkräfte praktisch nur parallel zur Haftfläche.Carrier parts for the tensioning device are preferably fastened to the vacuum holding devices and generally protrude a few centimeters from the latter. In this case, inadmissible tilting moments are avoided by the fact that the tensioning device itself is rigid (for example, a rod or profile body variable in length) and that it is rigidly attached to the supporting parts in such a way that it acts parallel to the adhesive surface. As a result, the clamping forces practically only act parallel to the adhesive surface.

Gemäß einer weiteren bevorzugten Ausführungsform hat die spannvorrichtung eine Zugkraftbegrenzungseinrichtung, durch die die Kraft, die zwischen den Halteelementen parallel zu der Plattenoberfläche wirkt auf einen vorbestimmbaren Maximal­wert einstellbar ist. Dadurch wird eine Überlastung der Arbeits­platten und das weiter oben erwähnte verhältnismäßig unkontrol­lierte Rutschen der Haftvorrichtungen vermieden. Darüberhinaus kann die Kraft, mit der die Kanten der Platten durch das HIlfs­werkzeug aneinandergedrückt werden auf die Eigenschaften des Klebstoffes bzw. Klebemittels, mit dem die Platten verbunden werden, abgestimmt werden. Infolgedessen läßt sich auf ein­fache Weise eine gleichmäßige, qualitativ hochwertige Verbindung der Platten erreichen.According to a further preferred embodiment, the tensioning device has a tensile force limiting device by means of which the force which acts between the holding elements parallel to the plate surface can be set to a predeterminable maximum value. This prevents overloading of the worktops and the relatively uncontrolled slipping of the adhesive devices mentioned above. In addition, the force with which the edges of the plates are pressed together by the auxiliary tool can be matched to the properties of the adhesive or adhesive to which the plates are connected. As a result, a uniform, high-quality connection of the plates can be achieved in a simple manner.

Die Erfindung wird im folgenden anhand eines in den Figuren schematisch dargestellten Ausführungsbeispiels näher er­läutert. Es zeigen:

  • Fig. 2 ein Hilfswerkzeug nach Fig. 1 im Schnitt in der Anwendung zum Verspannen von zwei Platten
  • Fig. 3 einen Längsschnitt durch eine Spannvorrichtung für ein erfindungsgemäßes Hilfswerkzeug in einer gegenüber Fig. 2 abgewandelten Ausführungsform
  • Fig 4 einen Querschnitt durch eine weitere abgewandelte Ausführungsform einer Spannvorrichtung
The invention is explained in more detail below on the basis of an exemplary embodiment shown schematically in the figures. Show it:
  • Fig. 1 shows an auxiliary tool according to the invention in a perspective view
  • Fig. 2 shows an auxiliary tool according to Fig. 1 in section in the application for bracing two plates
  • FIG. 3 shows a longitudinal section through a clamping device for an auxiliary tool according to the invention in an embodiment modified from FIG. 2
  • 4 shows a cross section through a further modified embodiment of a tensioning device

Das in den Figuren dargestellte Hilfswerkzeug 1 besteht im wesentlichen aus zwei Vakuumhaftvorrichtungen 2 und 3, an denen jeweils ein Tragteil 4,5 befestigt ist und aus einem die Vakuumhaftvorrichtungen verbindenden Handgriff 6.The auxiliary tool 1 shown in the figures consists essentially of two vacuum holding devices 2 and 3, to each of which a supporting part 4, 5 is fastened and a handle 6 connecting the vacuum holding devices.

In Fig.2 ist das Hilfswerkzeug 1 in Funktion dargestellt. Die Platten 7,8 sollen an ihren Kanten 9,10, welche mit ei­nem nicht dargestellten Klebstoff bestrichen sind, mitein­ander verbunden werden.The auxiliary tool 1 is shown in operation in FIG. The plates 7, 8 are to be connected to one another at their edges 9, 10, which are coated with an adhesive (not shown).

Zu diesem Zweck wird das Hilfswerkzeug 1 mit den beiden vakuumhaftvorrichtungen 2,3 - wie dargestellt - auf die glatte Oberfläche 11,12 der Platten 7,8 aufgesetzt. Der Teil der Oberfläche, auf dem die Haftvorrichtungen 2,3 haf­ten, wird als Haftfläche bezeichnet.For this purpose, the auxiliary tool 1 with the two vacuum holding devices 2, 3 - as shown - is placed on the smooth surface 11, 12 of the plates 7, 8. The part of the surface on which the adhesive devices 2, 3 adhere is referred to as the adhesive surface.

Die Vakuumhaftvorrichtungen 2,3 haben jeweils eine starre, beispielsweise aus Metall hergestellte, etwa tellerförmige Membranhalterung 2a und 3a und eine darunter angeordnete gummielastische Membran 2b, 3b. Der Mittelteil der gummi­elastischen Membranen 2b, 3b läßt sich mit Hilfe von Fest­spannelementen 13,14 anheben, die uber Handgriffe 15,16 betätigt werden können.The vacuum holding devices 2, 3 each have a rigid, for example made of metal, approximately plate-shaped membrane holder 2a and 3a and a rubber-elastic membrane 2b, 3b arranged underneath. The middle part of the rubber-elastic membranes 2b, 3b can be raised with the aid of clamping elements 13, 14, which can be actuated by means of handles 15, 16.

Von jeder Vakuumhaftvorrichtung 2,3 steht ein Tragteil 4,5 hervor, an dessen Oberende jeweils ein Lager vorgesehen ist, in dem der Handgriff 6 drehbar gelagert ist.From each vacuum holding device 2, 3 there is a supporting part 4, 5, at the upper end of which a bearing is provided, in which the handle 6 is rotatably mounted.

Das in Fig. 2 linke Lager 17 hat einen Gleitlagerring 17a, in den ein Lagerzapfen 6a des Handgriffs 6 eingreift. Auf dem Zapfen 6a sitzt ein Haltering 6b, durch den der Zapfen 6a gehalten wird, wenn eine Kraft zu der anderen Haftvorrichtung 3 hin wirkt. Auf der in der Figur rechten Seite geht der Halte­griff 6 in eine Gewindespindel 6c über, die in ein entspre­chendes Gewinde 18 eines am Tragteil 5 befestigten Lagers 19 eingreift.The left bearing 17 in FIG. 2 has a slide bearing ring 17a, in which a bearing pin 6a of the handle 6 engages. On the pin 6a is a retaining ring 6b, by which the pin 6a is held when a force acts on the other adhesive device 3. On the right-hand side in the figure, the handle 6 merges into a threaded spindle 6c, which engages in a corresponding thread 18 of a bearing 19 fastened to the supporting part 5.

Der Griff 6 und die Lager 17,19 bilden eine Spannvorrichtung, durch die die Vakuumhaftvorrichtungen 2,3 gegeneinander ver­schiebbar sind. Um eine feinfühlige Verschiebung zu gewähr­leisten, ist das Gewinde 18 als Feingewinde ausgebildet.The handle 6 and the bearings 17, 19 form a tensioning device through which the vacuum holding devices 2, 3 can be displaced relative to one another. In order to ensure a sensitive displacement, the thread 18 is designed as a fine thread.

Nach dem Aufsetzen des Hilfswerkzeugs werden die Festspann­elemente 13, 14 betätigt, so daß die Membranen 2b, 3b in der Mitte angehoben werden und darunter die Hohlräume 20,21 entstehen, in denen ein Vakuum herrscht. Durch das Vakuum werden die Haftvorrichtungen an den glatten Haftflächen 11a, 12 a festgehalten.After attaching the auxiliary tool, the clamping elements 13, 14 are actuated, so that the membranes 2b, 3b are raised in the middle and the cavities 20, 21 are formed below, in which a vacuum prevails. The adhesive devices are held on the smooth adhesive surfaces 11a, 12a by the vacuum.

Danach wird der Griff in der Weise gedreht, daß die Gewinde­spindel 6c in das Gewinde 18 eindringt. Dadurch werden die Vakuumhaftvorrichtungen aufeinander zu verschoben, bis die Kanten 9, 10 der Platten 7,8 aneinanderliegen. Die Kraft, mit der sie gegeneinandergedrückt werden, läßt sich dadurch variieren, daß der Handgriff mehr oder weniger stark weiter­gedreht wird. Bei zu großer Kraftaufwendung beginnen die Vakuumhaftvorrichtugen 2,3 auf den entsprechenden Oberflä­chen 11, 12 zu rutschen, so daß automatisch ein zu starkes Spannen vermieden wird. Wie aus Fig. 2 zu ersehen ist, ver­läuft die Achse A des Handgriffs 6 (und damit zugleich des Zapfens 6a und der Gewindespindel 6c) parallel zu den Haft­flächen 11a und 12a. Die Lager 17 und 19 sind über die Trag­teile 4,5 starr mit den Vakuumhaftvorrichtungen 2,3 verbun­den. Durch diese Maßnahme wird vermieden, daß bei dem Spann­vorgang ein Kippmoment auf die Haftvorrichtungen 2,3 wirkt und diese abheben könnte.The handle is then rotated in such a way that the threaded spindle 6c penetrates into the thread 18. As a result, the vacuum holding devices are moved towards one another until the edges 9, 10 of the plates 7, 8 lie against one another. The force with which they are pressed against each other can be varied by turning the handle more or less. If too much force is applied, the vacuum holding devices 2, 3 begin to slide on the corresponding surfaces 11, 12, so that excessive tensioning is automatically avoided. As can be seen from Fig. 2, the axis A of the handle 6 (and thus of the pin 6a and the threaded spindle 6c) runs parallel to the adhesive surfaces 11a and 12a. The bearings 17 and 19 are rigidly connected to the vacuum holding devices 2, 3 via the supporting parts 4, 5. By this measure it is avoided that during the tensioning process a tilting moment acts on the holding devices 2, 3 and could lift them off.

In Fig 3 ist eine ebenfalls als drehbarer Handgriff ausge­bildete Ausführungsform einer Spannvorrichtung dargestellt, bei der eine Zugkraftbegrenzung vorgesehen ist Die Zugkraft­begrenzungseinrichtung besteht bei der dargestellten Aus­führungsform aus zwei Permanentmagneten 30, 31, die gemeinsam einen zylindrischen Zugbolzen bilden und deren plane Stirn­flächen 30a, 31a gegeneinander anliegen Die Stirnflächen haben verschiedene magnetische Polarität, so daß sie gegen­einander angezogen werden.FIG. 3 shows an embodiment of a tensioning device, which is also designed as a rotatable handle, in which a tensile force limitation is provided. The tensile force limitation device in the embodiment shown consists of two permanent magnets 30, 31, which together form a cylindrical tension bolt and whose flat end faces 30a, 31a abut against each other The end faces have different magnetic polarities so that they are attracted to each other.

Die Permanentmagneten 30, 31 sind von einer nichtmagnetischen Drehhülse 32 umgeben und in axialer Richtung geführt. Um ein gegenseitiges Drehen zu vermeiden hat die Drehhülse zwei Führungsstifte 33, 34, die in eine entsprechende Längsnut 35 der beiden von den Permanentmagneten 30, 31 gebildeten Zugbolzen­hälften eingreifen.The permanent magnets 30, 31 are surrounded by a non-magnetic rotating sleeve 32 and are guided in the axial direction. In order to avoid mutual rotation, the rotating sleeve has two guide pins 33, 34 which engage in a corresponding longitudinal groove 35 of the two halves of the draw bolt formed by the permanent magnets 30, 31.

Eine weitere Abwandlung der in Fig 3 dargestellten Ausführungs­form gegenüber Fig 2 besteht darin, daß die Drehbewegung des Handgriffes 6 in diesem Falle mit Hilfe zweier gegenläufiger Gewinde in eine Axialbewegung umgesetzt wird. Entsprechende Gewindezapfen 34, 35 der Permanentmagneten 30, 31 dringen in Gewindehülsen 36, 37 der Lager 17, 19 ein. Durch diese Ausführung mit zwei Gewinden wird eine symmetrische Verschiebung der Tragteile 4, 5 gegeneinander erreicht.A further modification of the embodiment shown in FIG. 3 compared to FIG. 2 is that the rotary movement of the handle 6 in this case is converted into an axial movement with the aid of two opposing threads. Corresponding threaded pins 34, 35 of the permanent magnets 30, 31 penetrate into threaded sleeves 36, 37 of the bearings 17, 19. This design with two threads results in a symmetrical displacement of the supporting parts 4, 5 relative to one another.

Die Permanentmagneten 30, 31 sind so ausgelegt, daß bei einer vorbestimmten axialen Zugkraft ihre gegenseitige Haltekraft überschritten und infolgedessen der Zugbolzen in der Mitte getrennt wird.The permanent magnets 30, 31 are designed so that their mutual holding force is exceeded at a predetermined axial tensile force and, as a result, the draw bolt is separated in the middle.

Fig. 4 dient dazu, eine weitere Ausführungsform einer Zugkraft­begrenzungsvorrichtung mit Hilfe formschlüssig zusammenwirkender Elemente zu verdeutlichen. Auch in diesem Fall ist die Spann­vorrichtung als drehbarer Handgriff ähnlich Fig 2 ausgebildet, wobei der Handgriff 6 jedoch in diesem Fall aus einem äußeren zylinderförmigen Drehgriff 40 und einem in der Zylinderbohrung geführten Führungsbolzen 41 besteht. Dabei sind der Drehgriff 40 und der Führungsbolzen 41 jeweils in einem der Lager 17, 19 gelagert, wobei die Drehbewegung nach einem der in den Figuren 2 und 3 dargestellten Prinzipien in eine Axialbewegung umgesetzt wird.4 serves to illustrate a further embodiment of a tensile force limiting device with the aid of form-fittingly interacting elements. In this case too, the tensioning device is designed as a rotatable handle similar to FIG. 2, but in this case the handle 6 consists of an outer cylindrical rotary handle 40 and a guide pin 41 guided in the cylinder bore. The rotary handle 40 and the guide pin 41 are each mounted in one of the bearings 17, 19, the rotary movement being converted into an axial movement according to one of the principles shown in FIGS. 2 and 3.

Die Zugkraftbegrenzungseinrichtung wird durch eine Kugel 42 gebildet, die in eine entsprechende Ausnehmung 43 des inneren Führungsbolzens 41 eingreift Die Kugel 42 wird durch eine feder 44, deren Federkraft mit Hilfe einer Einstellschraube 45 einstellbar ist, gegen die Ausnehmung 43 gedrückt.The tensile force limiting device is formed by a ball 42 which engages in a corresponding recess 43 of the inner guide pin 41. The ball 42 is pressed against the recess 43 by a spring 44, the spring force of which can be adjusted with the aid of an adjusting screw 45.

Wenn ein zu starkes Drehmoment zwischen den Bauteilen 40 und 41 wirkt, rastet die Kugel in radialer Richtung aus, so daß die formschlüssige Verbindung zwischen dem Drehgriff 40 und dem Führungsbolzen 41 aufgehoben wird. Entsprechendes gilt auch bei zu hoher Kraft in axialer Richtung, wobei dann die Kugel axial ausrastet. Durch entsprechende Formgebung der form­schlüssig zusammenwirkenden Bauteile 42, 43, insbesondere durch Gestaltung der Nut 43, kann die vorbestimmte maximale Kraft, auf die die Zugkraft begrenzt wird, eingestellt werden.If excessive torque acts between the components 40 and 41, the ball disengages in the radial direction, so that the positive connection between the rotary handle 40 and the guide pin 41 is canceled. The same applies to excessive force in the axial direction, in which case the ball disengages axially. The predetermined maximum force, to which the tensile force is limited, can be set by appropriate shaping of the components 42, 43 that cooperate in a form-fitting manner, in particular by designing the groove 43.

Alternativ zu den beiden dargestellten Ausführungsformen kann die Zugkraftbegrenzung auch in anderer Weise, beispielsweise mit Hilfe eines Scherstiftes oder einer Rutschkupplung, reali­siert werden.As an alternative to the two illustrated embodiments, the tractive force limitation can also be implemented in a different way, for example with the aid of a shear pin or a slip clutch.
