- Figures 14 and 15 and is otherwise similar to the rung holder described above Figures 7 and 8 designed.
- the spacer 4 has a rectangular cross section with two opposite broad sides 41 and 42 and two opposite narrow sides 43 and 44. If the spacer 4 is designed as a spacer band, the narrow sides 43, 44 are each set up to be placed on the respective glass panel 2, 3. For this purpose, the narrow sides 43, 44 can have grooves and/or gradations in a manner not shown but known per se for receiving adhesive, which bonds the spacer 4 to the glass panels 2, 3.
- the magnet 15 is inserted into the spacer 4 from the broad side 42 facing the inside of the insulating glass pane 1.
- the opposite broadside 41 remains intact. This can be advantageous if the spacer tape is provided on its broad side 41 with a water vapor impermeable film in a manner known per se.

- the exemplary embodiments are: Figures 11 and 12 in the same way as the exemplary embodiment Figure 9 designed.
- the rung holder 9 is also formed in one piece with the magnet 19, but is inserted into the spacer 4 from the outward-facing broad side 41. This can be advantageous if the spacer 4 was applied as a plastic strand to the glass panel 2 and the magnet 18 is then inserted into the still plastic strand. There is more space available on the outside of the spacer 4 for a device for inserting the magnet 19.
- the pointed thorn 33 is pierced through the spacer 4 and protrudes from the spacer 4 on the inward-facing broad side 42. To insert the rung insert 5, a corresponding distance 45 of the end 7 from the spacer 4 is therefore required.
- the magnet 18 is also mounted in the rung holder 8 by means of a linear guide 26.
- An additional magnet 24 can also be provided here in a manner not shown.
- the magnet pair 28 consisting of the magnets 18 and 19 thus holds the rung insert 5 in position in a form-fitting manner.

Die Sprossenhalterung kann den wenigstens einen Magneten und einen Magnethalter, insbesondere aus Kunststoff, umfassen. Der Magnet, insbesondere der Hartmagnet, ist beweglich in der Sprossenhaltererung angeordnet, und zwar in entlang der Längsrichtung der Sprosse beweglicher Weise. Die Sprossenhaltung kann dabei als Sprossenendstück ausgebildet sein. Das Sprossenendstück kann in ein Ende einer hohlen Sprosse einsetzbar sein. Eine als Sprossenendstück ausgebildete Sprossenhalterung kann insbesondere einen Magneten aus einem hartmagnetischen Werkstoff enthalten.The rung holder according to the invention for attaching the rung insert to the spacer of the insulating glass pane contains at least one magnet. The rung holder is set up to hold the magnet on the rung insert or on the spacer. The rung holder can be formed in one piece with the magnet, in particular made of soft magnetic material. The rung holder can consist of a single part if it is designed as a magnet. A one-piece rung holder can be designed to be inserted into the spacer. Alternatively, the rung holder can consist of several parts. The rung holder can include at least one magnet and a magnet holder, in particular made of plastic. The magnet, in particular the hard magnet, is movably arranged in the rung holder, specifically in a movable manner along the longitudinal direction of the rung. The rung holder can be designed as a rung end piece. The rung end piece can be inserted into one end of a hollow rung. A rung holder designed as a rung end piece can in particular contain a magnet made of a hard magnetic material.
Bei dem erfindungsgemäßen Verfahren zum Herstellen einer Isolierglasscheibe mit einem durch Magnetkraft gehaltenen Sprosseneinsatz wird der Abstandhalter aus einem kunststoffbasierten Material rahmenförmig auf eine erste der Glastafeln appliziert. Der Abstandhalter verläuft entlang der Ränder der Glastafel. In den Abstandhalter wird wenigstens ein Magnet eingesetzt. Dies kann vor oder nach dem Applizieren des Abstandhalters auf die erste Glastafel erfolgen. Der Magnet kann in einer Sprossenhalterung enthalten sein, welche in den Abstandhalter eingesetzt wird. An den rahmenförmigen Abstandhalter, welcher sich auf der ersten Glastafel befindet und mit wenigstens einem Magneten versehen ist, wird dann der Sprosseneinsatz angesetzt. Jeweils ein Magnet in dem Sprosseneinsatz und ein Magnet in dem Abstandhalter wirken zusammen und bilden ein Magnetpaar, welches den Sprosseneinsatz in Position hält. Nach dem Ansetzen des Sprosseneinsatzes wird der rahmenförmige Abstandhalter mit einer zweiten der Glastafeln zusammengefügt, sodass sich der Abstandhalter und der Sprosseneinsatz zwischen der ersten und der zweiten Glastafel befinden. Dabei können sich in an sich bekannter Weise weitere Verfahrensschritte, wie beispielsweise ein Gasfüllen, zwischen- oder nachgeschaltet werden.In the method according to the invention for producing an insulating glass pane with a rung insert held by magnetic force, the spacer made of a plastic-based material is applied in a frame shape to a first of the glass panels. The spacer runs along the edges of the glass panel. At least one magnet is inserted into the spacer. This can be done before or after applying the spacer to the first glass panel. The magnet can be contained in a rung holder, which is inserted into the spacer. The rung insert is then attached to the frame-shaped spacer, which is located on the first glass panel and is provided with at least one magnet. One magnet in the rung insert and one magnet in the spacer work together and form a pair of magnets that hold the rung insert in position. After attaching the rung insert, the frame-shaped spacer is joined to a second of the glass panels so that the spacer and the rung insert are located between the first and the second glass panel. Included Further process steps, such as gas filling, can be interposed or followed in a manner known per se.
Als Abstandhalter kann beispielsweise ein plastischer Strang verwendet werden, welcher mit einer vorgegebenen Solldicke auf die erste Glastafel appliziert wird. Der Strang kann insbesondere aus einem thermoplastischen Kunststoffmaterial bestehen. Ein Verfahren und eine Vorrichtung zum Auftragen eines plastischen Strangs als Abstandhalter sind aus der
Alternativ kann als Abstandhalter auch ein ein von der Rolle zu verarbeitendes vorgefertigtes Band aus Kunststoff eingesetzt werden, welches beispielsweise aus der
Die Erfindung hat wesentliche Vorteile:
- Das Ansetzen eines Sprosseneinsatzes an einen Abstandhalter aus einem kunststoffbasierten Material, insbesondere aus einem noch plastischen Strang, kann einfacher und besser durchgeführt werden. Dies vereinfacht insbesondere den Montageprozess bei der Herstellung der Isolierglasscheibe deutlich.
- Beim Ansetzen des Sprosseneinsatzes an den rahmenförmigen Abstandhalter wirken im Wesentlichen nur die Magnetkräfte auf den Abstandhalter. Diese sind sehr gering. Die Gefahr, dass sich der Abstandhalter in unerwünschter Weise verformt oder beim Ansetzen beschädigt wird, wird dadurch minimiert.
- Gleichwohl reichen die Haltekräfte von den Magneten aus, um den Sprosseneinsatz sicher in Position zu halten. Nachdem vollständigen Zusammenbau der Isolierglasscheibe ist der Sprosseneinsatz präzise und sicher im Inneren der Isolierglasscheibe gehalten.
- Die Magnetbefestigung des Sprosseneinsatzes am Abstandhalter ermöglicht eine Positionierung des Sprosseneinsatzes derart zwischen den beiden Glastafeln, dass der Sprosseneinsatz keine der beiden Glastafeln berührt. Dies ist insbesondere vorteilhaft, wenn die Glastafeln auf ihrer nach innen weisenden Oberfläche eine Beschichtung aufweisen. Auch die Sprossenhalterungen bzw. Magnete berühren die Glastafeln nicht.
- Das Einsetzen der Sprossenhalterungen in den Abstandhalter kann leicht automatisiert werden. Dadurch lässt sich eine sehr genaue Positionierung des Sprosseneinsatzes in dem rahmenförmigen Abstandhalter bzw. in der Isolierglasscheibe gewährleisten.
- Insgesamt kann das Erscheinungsbild und die Qualität von Isolierglasscheiben mit eingesetztem Sprossenrahmen verbessert werden.
- Attaching a rung insert to a spacer made of a plastic-based material, in particular a strand that is still plastic, can be carried out more easily and better. This significantly simplifies the assembly process in particular when producing the insulating glass pane.
- When the rung insert is placed on the frame-shaped spacer, essentially only the magnetic forces act on the spacer. These are very low. This minimizes the risk that the spacer will deform in an undesirable manner or be damaged when it is placed.
- Nevertheless, the holding forces from the magnets are sufficient to hold the rung insert securely in position. After the insulating glass pane has been completely assembled, the rung insert is held precisely and securely inside the insulating glass pane.
- The magnetic attachment of the rung insert to the spacer enables the rung insert to be positioned between the two glass panels in such a way that the rung insert does not touch either of the two glass panels. This is particularly advantageous if the glass panels have a coating on their inward-facing surface. The rung holders or magnets also do not touch the glass panels.
- Inserting the rung holders into the spacer can be easily automated. This ensures very precise positioning of the rung insert in the frame-shaped spacer or in the insulating glass pane.
- Overall, the appearance and quality of insulating glass panes with inserted lattice frames can be improved.
In Ausgestaltung der Erfindung kann das Abstandhalterband mehrere Magnete enthalten, welche entlang der Längsrichtung des Abstandhalterbandes in vorbestimmten Abständen eingesetzt sind. Dies kann für eine rationelle Fertigung von Isolierglasscheiben in Standardformaten vorteilhaft sein.In an embodiment of the invention, the spacer band can contain a plurality of magnets which are inserted at predetermined intervals along the longitudinal direction of the spacer band. This can be advantageous for the efficient production of insulating glass panes in standard formats.
In weiterer Ausgestaltung der Erfindung kann einer der Magnete des Magnetpaares bzw. die diesen enthaltende Sprossenhalterung in den Abstandhalter eingesetzt sein. Der andere Magnet des Magnetpaares bzw. die diesen enthaltende Sprossenhalterung kann in dem Sprosseneinsatz angeordnet sein, insbesondere beweglich in einem seiner Enden. Insbesondere kann der Hartmagnet in dem Sprosseneinsatz und der Weichmagnet in dem Abstandhalter angeordnet sein. Insbesondere ist an beiden Enden der Sprosse jeweils wenigstens ein Magnet angeordnet. Eine Sprossenhalterung kann zwei oder mehr Magnete enthalten, um eine höhere Haltekraft für den Sprosseneinsatz bereitzustellen.In a further embodiment of the invention, one of the magnets of the magnet pair or the rung holder containing it can be inserted into the spacer. The other magnet of the magnet pair or the rung holder containing it can be arranged in the rung insert, in particular movable in one of its ends. In particular, the hard magnet can be arranged in the rung insert and the soft magnet in the spacer. In particular, at least one magnet is arranged at both ends of the rung. A rung holder may contain two or more magnets to provide greater holding force for the rung insert.
Der wenigstens eine Magnet kann in beweglicher Weise in dem Magnethalter angeordnet sein, und zwar entlang der Längsrichtung der Sprosse beweglich. In Ausgestaltung kann der wenigstens eine Magnet beweglich an der Sprossenhalterung befestigt sein. Es kann eine Linearführung für den Magneten vorgesehen sein, um den Magneten entlang der Längsrichtung der Sprosse beweglich zu führen. Der Sprosseneinsatz und/oder der Magnethalter kann die Linearführung enthalten. Der Magnet kann einen zylindrischen Abschnitt aufweisen, mit welchem er in der Linearführung sitzt und relativ zu dem Magnethalter und/oder dem Sprosseneinsatz verschiebbar ist. Der Magnet kann eine Vertiefung zum Kontaktieren des anderen Magneten des Magnetpaares in der Isolierglasscheibe aufweisen. Hierdurch entsteht ein Formschluss zwischen den Magneten, welcher die Haltekräfte des Magnetpaares erhöht. In der Sprossenhalterung kann ein Zusatzmagnet fixiert sein. Der Zusatzmagnet ist unbeweglich in dem Magnethalter befestigt.The at least one magnet can be arranged in a movable manner in the magnet holder, namely movable along the longitudinal direction of the rung. In one embodiment, the at least one magnet can be movably attached to the rung holder. A linear guide can be provided for the magnet in order to movably guide the magnet along the longitudinal direction of the rung. The rung insert and/or the magnet holder can contain the linear guide. The magnet can have a cylindrical section with which it sits in the linear guide and can be moved relative to the magnet holder and/or the rung insert. The magnet can have a recess for contacting the other magnet of the magnet pair in the insulating glass pane. This creates a positive connection between the magnets, which increases the holding forces of the pair of magnets. An additional magnet can be fixed in the rung holder. The additional magnet is fixed immovably in the magnet holder.
In weiterer Ausgestaltung kann die Sprossenhalterung wenigstens einen Vorsprung aufweisen. Mithilfe des Vorsprungs ist die Sprossenhalterung in den Sprosseneinsatz oder in den Abstandhalter einsetzbar. Der Vorsprung kann einstückig mit dem Magneten oder dem Magnethalter ausgeformt sein. Der Vorsprung ist zum Halten der Sprossenhalterung in dem Sprosseneinsatz bzw. in dem Abstandhalter eingerichtet. Hierzu kann der Vorsprung eine Spitze zum Einstechen in den Abstandhalter aufweisen. Der Vorsprung kann als spitzer Dorn ausgebildet sein. Der Vorsprung kann scharfkantige Fortsätze und/oder Widerhaken zum Halten des Magneten in dem Abstandhalter und/oder der Sprosse enthalten.In a further embodiment, the rung holder can have at least one projection. Using the projection, the rung holder can be inserted into the rung insert or into the spacer. The projection can be formed in one piece with the magnet or the magnet holder. The projection is designed to hold the rung holder in the rung insert or in the spacer. For this purpose, the projection can have a tip for piercing the spacer. The projection can be designed as a pointed thorn. The projection can contain sharp-edged extensions and/or barbs for holding the magnet in the spacer and/or the rung.

Der Magnethalter 21 weist Vorsprünge 23 auf, welche in den Abstandhalter 4 eingedrückt werden. Die Vorsprünge 23 sind spitz und/oder scharfkantig ausgeführt, um die Sprossenhalterung 8 in dem noch plastischen Strang des Abstandhalters 4 zu verankern.The
Die Sprossenhalterung 8 enthält Zusatzmagnete 24 und 25, welche in dem Magnethalter 20 fixiert sind. Der Zusatzmagnet 24 ist dem Magneten 10 und der Zusatzmagnet 25 dem Magneten 12 zugeordnet. Der Magnethalter 20 enthält ferner Linearführungen 26. Die Linearführungen 26 verlaufen in Längsrichtung der Sprosse 6. Jeder der Magnete 10, 12 ist mit einem zylindrischen Abschnitt in der jeweiligen Linearführung 26 relativ zu dem Magnethalter 20 verschiebbar gelagert. Die Magnete 10 und 12 sind Hartmagnete. Bei den Magneten 11 und 13 sowie bei den Zusatzmagneten 24 und 25 handelt es sich um Weichmagnete. Vor dem Einbau des Sprossenhalters 8 in das Ende 7 sitzen die Magnete 10 und 12 vollständig in dem Magnethalter 20 und stehen mit den Zusatzmagneten 24, 25 in Kontakt, vgl.
Nach dem Applizieren des rahmenförmigen Abstandhalters 4 auf die erste Glastafel 2 wird für jedes Ende 7 eine Sprossenhalterung 9 an der entsprechenden Position in den Abstandhalter 4 eingesetzt. Dabei kann falls nötig gegengehalten werden, um ein unbeabsichtigtes Verschieben des Abstandhalters 4 zu vermeiden. Anschließend wird der vorbereitete Sprosseneinsatz 5, welcher an jedem Ende 7 eine Sprossenhalterung 8 enthält, an den Abstandhalter 4 angesetzt. Beim Ansetzen des Sprosseneinsatzes 5 an den Abstandhalter 4 wird der Magnet 10 von dem Magneten 11 angezogen. Wenn sich aufgrund von Maßtoleranzen ein kleiner Spalt 31 zwischen den beiden Sprossenhalterungen 8 und 9 befindet, so wird der Magnet 10 ein Stück weit aus der Linearführung 26 herausgezogen bis er mit dem Magneten 11 in Kontakt steht, vgl.
