Definitions
- the invention relates to a linear connector for hollow, provided with a perforation Distance profiles of a multi-pane insulating glass, with a flat elongated body, whose cross section rectilinearly to the cavity cross section of the two connecting spacing profiles is adapted and preferably corresponds to this, and from consists of two parts, one part in the one spacing profile and the other part can be inserted into the other spacing profile of the two profiles to be connected to one another are, and the surface of which is provided with at least one upstanding center stop is that when inserting the linear connector into the spacer profiles with their Leading edges come into contact.
- linear connectors are, for example, from DE-OS 28 09 822 and G 90 16 592 known.
- the problem with linear connectors of this and similar type is that after insertion or insertion into the cavity of the associated spacing profiles the frictional effect between the surface of the linear connector and it surrounding inner wall of the spacer profiles often leaves something to be desired, although in In many cases, additional spring elements on or in the surface of the linear connector Find use that attach themselves to the wall of the cavity to the frictional force to increase and thereby prevent the junction of the spacer profiles opens again after installing the linear connector.
- the object of the invention is therefore to continue the linear connector to improve that between its surface and the inner wall surface of the Spacer profile occurring friction is increased, so that a tight fit after installation the linear connector is guaranteed, especially in cases where, how common with insulating glass panes nowadays, the spacing profiles are provided with a perforation are, which has the task of the air in the space between the panes in the To allow clearance profile cavity to dehumidify the air with the help of the to effect this cavity molecular sieve.
- the center stop as part of a Cutting edge brake on the top of the elongated body has a cross rib to which Adjacent wedges rising from the surface of the upper side on both sides, whose highest elevation is below the apex of the cross rib, and that at the parallel side faces of the elongated body in the area of the transverse rib and several wedges are arranged side by side spaced ribs, their apex height increases on both sides of the cutting edge brake towards the transverse rib and at those of the transverse rib on next lying side ribs is so large that the width of the linear connector, characterized by the distance between the side surfaces, is slightly larger than outside this Area, the cross rib of the cutting edge brake with respect to the side ribs so is arranged that its lateral extension lies in a side rib valley.
- the linear connector shown in Fig. 1 consists of a known rigid plastic material and has an almost rectangular cross section. Its flat, elongated body 1 is used to connect the hollow spacer profiles 4, 5 and is for this purpose with its parts 2 and 3 in the two Inserted spacer profiles until the profile faces 7 and 8 at its center stop, which as part of a cutting edge brake on the top 7 of the elongated body 1 has a transverse rib 6. Wedges 8, 9 rising from the surface of the upper side to the transverse rib border on both sides of it, the highest elevation of which lies below the apex of the transverse rib 6.
- wedges 8, 9 are part of the cutting edge brake, by means of which the cutting edge, which can form when the linear connector is pushed into the cavity of the spacing profiles, is scraped off by the fact that the front edges 15, 16 of the spacing profiles scrape plastic material from the surface of the linear connector and push in front, in the space 10 mixing the front edge edges 17, 18 of the wedges 8, 9 and the transverse rib 6 shown in FIG. 3 is deposited. This prevents this degree of cutting, that is the scraped-off material, from building up in front of the transverse rib 6 and preventing extensive joining of the front edges 15, 16 of the spacer profiles 4, 5. To reinforce this effect, the cross rib 6 of the cutting edge brake is longer than the wedges 8, 9 are wide.
- the transverse rib 6 At the extension of the center line designated 19 there is the transverse rib 6, that is, the transverse rib is arranged with respect to the side ribs 13 so that their lateral extension falls into a side rib valley 14.
- the distance A of the individual side ribs 13 from each other in the illustrated embodiment, as shown in FIG. 4 is 1.5 mm and the height of the side ribs increases in the direction of the center of the elongated body 1 and thus in the direction of the transverse rib 6, as Already stated above, in the embodiment shown by 0.1 mm each.
- the side ribs 13 extend only over part of the total height H of the elongated body 1 by being arranged in the region of the cutting edge brake consisting of the wedges 8, 9 and the transverse rib 6.
- the side ribs as can be seen from Fig. 3 , have a cross section which corresponds to an isosceles triangle whose apex angle is 90 °, while the transverse rib 6 also has a triangular cross section which forms an isosceles triangle, the apex angle of which includes 30 °.
- the wall of the spacer profiles 4, 5 facing the space between the panes of insulating glass is usually provided with a perforation, i.e. with openings, through which a connection is made between the cavity of the spacer profiles and the space between the panes with the aim of using the air in the space between the panes to dehumidify filled in the cavity of the spacer profiles, also called molecular sieve.
- a perforation i.e. with openings
- the cutting edge brake formed from the transverse rib 6 and the wedges 8 and 9 can either be arranged on the upper side of the elongated body 1, as can be seen in FIG. 1 , or on the lower side 20, depending on the cutting edge direction of the saw when cutting the distance profiles.
- the linear connector shown in Fig. 5 also consists of a known rigid plastic material and has an almost rectangular cross section. Its flat, elongated body 21 is used to connect the hollow spacer profiles 24, 25, and for this purpose, as in the embodiment according to FIGS. 1 to 4 , its parts 22 and 23 are inserted into the two spacer profiles until the profile faces 27 and 27, respectively 28 abut the center stop 26, on which the so-called cutting edge brake in the form of a wedge 220, 221 rising to the upper edge of the stop 6 is positioned at a short distance on both sides.
- These openings 212 are made in that for example with the help of a spiked roller, the hollow profile wall is pierced, whereby the breakthrough edges usually form a sharp-edged ridge at the penetration points, which is indicated schematically in Fig. 5 at 210.
- corrugations 213, 214 are in the form of themselves transverse to the longitudinal direction of the Body 1 extending and strip-like in the insertion direction at a distance one behind the other ribs 215 which, as shown in FIG.
- each use a row of ribs which are known within slot-shaped material recesses 218, 219 and, as shown at 223 and 224, May have interruptions, which may be due to mold construction, by ejectors for the injection molded part, ie the Linear connector, sit.
- the depth of the sawtooth-like profile of the ribs 215 shown in FIG. 1 is 0.72 mm, the rib spacing approx. 2.5 mm, whereby these dimensions correspond to the existing ones Perforation breakthroughs 212 are adapted.
- Dimensions and location as well as size and type of corrugation or ribs are at least chosen so that the desired goal, namely a mechanical friction between the tips of the ribs and the perforations becomes.

Die Erfindung betrifft einen Linearverbinder für hohle, mit einer Perforation versehene Abstandsprofile eines Mehrscheibenisolierglases, mit einem flachen länglichen Körper, dessen Querschnitt an den Hohlraumquerschnitt der beiden miteinander geradlinig zu verbindenden Abstandsprofile angepaßt ist und diesem vorzugsweise entspricht, und der aus zwei Teilen besteht, von denen der eine Teil in das eine Abstandsprofil und der andere Teil in das andere Abstandsprofil der beiden miteinander zu verbindenden Profile einsteckbar sind, und dessen Oberfläche mit wenigstens einem aufstehenden Mittenanschlag versehen ist, der beim Einschieben des Linearverbinders in die Abstandsprofile mit deren Vorderkanten in Berührung tritt.The invention relates to a linear connector for hollow, provided with a perforation Distance profiles of a multi-pane insulating glass, with a flat elongated body, whose cross section rectilinearly to the cavity cross section of the two connecting spacing profiles is adapted and preferably corresponds to this, and from consists of two parts, one part in the one spacing profile and the other part can be inserted into the other spacing profile of the two profiles to be connected to one another are, and the surface of which is provided with at least one upstanding center stop is that when inserting the linear connector into the spacer profiles with their Leading edges come into contact.
Derartige Linearverbinder sind beispeilsweise aus der DE-OS 28 09 822 und dem G 90 16 592 bekannt. Bei Linearverbindern dieser und ähnlicher Art ergibt sich das Problem, daß nach dem Einschieben oder Einschlagen in den Hohlraum der zugehörigen Abstandsprofile die Reibungswirkung zwischen der Oberfläche des Linearverbinders und der sie umgebenden Innenwand der Abstandsprofile oftmals zu wünschen übrig läßt, obgleich in vielen Fällen auf bzw. in der Oberfläche des Linearverbinders zusätzliche Federelemente Verwendung finden, die sich an die Wandung des Hohlraums anlegen, um die Reibungskraft zu erhöhen und dadurch zu verhindern, daß sich die Verbindungsstelle der Abstandsprofile nach dem Einbau des Linearverbinders wieder öffnet. Such linear connectors are, for example, from DE-OS 28 09 822 and G 90 16 592 known. The problem with linear connectors of this and similar type is that after insertion or insertion into the cavity of the associated spacing profiles the frictional effect between the surface of the linear connector and it surrounding inner wall of the spacer profiles often leaves something to be desired, although in In many cases, additional spring elements on or in the surface of the linear connector Find use that attach themselves to the wall of the cavity to the frictional force to increase and thereby prevent the junction of the spacer profiles opens again after installing the linear connector.
Die Aufgabe der Erfindung besteht deshalb darin, den Linearverbinder weiter dahingehend zu verbessern, daß die zwischen seiner Oberfläche und der Innenwandoberfläche des Abstandsprofils auftretende Reibung verstärkt wird, so daß nach dem Einbau ein fester Sitz des Linearverbinders gewährleistet ist, und zwar insbesondere in den Fällen, in denen, wie bei Isolierglasscheiben heutzutage üblich, die Abstandsprofile mit einer Perforation versehen sind, die die Aufgabe hat, die in dem Scheibenzwischenraum befindliche Luft in den Abstandsprofilhohlraum eintreten zu lassen, um eine Entfeuchtung der Luft mit Hilfe des in diesem Hohlraum befindlichen Molekularsiebs zu bewirken.The object of the invention is therefore to continue the linear connector to improve that between its surface and the inner wall surface of the Spacer profile occurring friction is increased, so that a tight fit after installation the linear connector is guaranteed, especially in cases where, how common with insulating glass panes nowadays, the spacing profiles are provided with a perforation are, which has the task of the air in the space between the panes in the To allow clearance profile cavity to dehumidify the air with the help of the to effect this cavity molecular sieve.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Mittenanschlag als Teil einer Schneidgratbremse auf der Oberseite des länglichen Körpers eine Querrippe aufweist, an die beidseitig aus der Oberfläche der Oberseite zu ihr ansteigende Keile mit Abstand angrenzen, deren höchste Erhebung unterhalb des Scheitels der Querrippe liegt, und daß an den parallelen Seitenflächen des länglichen Körpers im Bereich der Querrippe und Keile mehrere mit Abstand hintereinanderliegende Seitenrippen angeordnet sind, deren Scheitelhöhe beidseitig der Schneidgratbremse zur Querrippe hin ansteigt und bei den der Querrippe am nächsten liegenden Seitenrippen so groß ist, daß die Breite des Linearverbinders, gekennzeichnet durch den Abstand der Seitenflächen, etwas größer ist als außerhalb dieses Bereiches, wobei die Querrippe der Schneidgratbremse in bezug auf die Seitenrippen so angeordnet ist, daß ihre seitliche Verlängerung in einem Seitenrippental liegt.This object is achieved in that the center stop as part of a Cutting edge brake on the top of the elongated body has a cross rib to which Adjacent wedges rising from the surface of the upper side on both sides, whose highest elevation is below the apex of the cross rib, and that at the parallel side faces of the elongated body in the area of the transverse rib and several wedges are arranged side by side spaced ribs, their apex height increases on both sides of the cutting edge brake towards the transverse rib and at those of the transverse rib on next lying side ribs is so large that the width of the linear connector, characterized by the distance between the side surfaces, is slightly larger than outside this Area, the cross rib of the cutting edge brake with respect to the side ribs so is arranged that its lateral extension lies in a side rib valley.
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche. Zu ihnen gehört insbesondere die Maßnahme, daß diejenige Oberflächenseite des länglichen Körpers, die mit der Innenseite der perforierten Wandfläche des Abstandsprofils, welche mit durch den Perforationsvorgang verursachten scharfen Ecken und Durchbruchrändern versehen ist, beim Einschieben des Linearverbinders in das Abstandsprofil in Berührung tritt, eine Feinstrukur, insbesondere eine Riffelung aufiveist, die mit den Perforationsecken und - rändern in Eingriff bringbar ist.Advantageous developments of the invention are the subject of the dependent claims. To them belongs in particular to the measure that the surface side of the elongated body, the one with the inside of the perforated wall surface of the spacer profile, which with through there are sharp corners and breakthrough edges in the perforation process, comes into contact when inserting the linear connector into the spacing profile Fine structure, in particular a corrugation with the perforation corners and - edges can be brought into engagement.
Diese besondere Maßnahme wird in Anspruch 21 als zusätzlicher Aspekt der Erfindung angegeben.This special measure is specified in

Der in Fig. 1 dargestellte Linearverbinder besteht aus einem bekannten steifen Kunststoffmaterial
und weist einen nahezu rechteckigen Querschnitt auf Sein flacher,
länglicher Körper 1 dient zur Verbindung der hohlen Abstandsprofile 4, 5 und wird zu
diesem Zweck mit seinen Teilen 2 bzw. 3 in die beiden Abstandsprofile hineingesteckt,
bis die Profilstirnseiten 7 bzw. 8 an seinem Mittenanschlag, der als Teil einer
Schneidgratbremse auf der Oberseite 7 des länglichen Körpers 1 eine Querrippe 6
aufweist. An diese Querrippe grenzen beidseitig von ihr aus der Oberfläche der Oberseite
zu ihr ansteigende Keile 8, 9 mit Abstand an, deren höchste Erhebung unterhalb des
Scheitels der Querrippe 6 liegt. Diese Keile 8, 9 sind Bestandteil der Schneidgratbremse,
durch die erreicht wird, daß der Schneidgrat, der sich beim Hineinschieben des
Linearverbinders in den Hohlraum der Abstandsprofile dadurch bilden kann, daß die
Vorderkanten 15, 16 der Abstandsprofile Kunststoffmaterial von der Oberfläche des
Linearverbinders abschaben und vor sich herschieben, in den Zwischenraum 10 Mischen
den in Fig. 3 gezeigten vorderen Randkanten 17, 18 der Keile 8, 9 und der Querrippe 6
abgelegt wird. Dadurch wird verhindert, daß dieser Schneidgrad, also das abgeschabte
Material, sich vor der Querrippe 6 aufbaut und ein weitgehendes Zusammenfügen der
Vorderkanten 15, 16 der Abstandsprofile 4, 5 verhindert. Um diesen Effekt zu verstärken,
ist die Querrippe 6 der Schneidgratbremse länger als die Keile 8, 9 breit sind.The linear connector shown in Fig. 1 consists of a known rigid plastic material and has an almost rectangular cross section. Its flat, elongated body 1 is used to connect the
An den parallelen Seitenflächen 11, 12 des länglichen Körpers 1 sind, wie aus den Fig. 1
und 2 ersichtlich, im Bereich der Querrippe 6 und Keile 8, 9 mehrere mit Abstand
hintereinander liegende Seitenrippen 13 angeordnet, deren Scheitelhöhe beidseitig der
Schneidgratbremse zur Querrippe 6 hin ansteigt und bei den der Querrippe am nächsten
liegenden Seitenrippen 13 so groß ist, daß die Breite des Linearverbinders,
gekennzeichnet durch den Abstand der Seitenflächen 11, 12, etwas größer ist als
außerhalb dieses Bereiches. Dies ist der vergrößerten Detaildarstellung von Fig. 4 zu
entnehmen. An der Verlängerung der mit 19 bezeichneten Mittellinie liegt dort die
Querrippe 6, d.h, die Querrippe ist in bezug auf die Seitenrippen 13 so angeordnet, daß
ihre seitliche Verlängerung in ein Seitenrippental 14 hineinfällt. Der Abstand A der
einzelnen Seitenrippen 13 voneinander beträgt bei dem dargestellten Ausführungsbeispiel,
wie aus Fig. 4 ersichtlich, 1,5 mm und die Höhe der Seitenrippen nimmt in
Richtung auf die Mitte des länglichen Körpers 1 und damit in Richtung auf die Querrippe
6, wie oben bereits ausgeführt, zu, und zwar bei dem gezeigten Ausführungsbeispiel um
jeweils 0,1 mm. Auf diese Weise bilden die Seitenrippen 13 in ihrer Aufeinanderfolge
beim Einschieben des Linearverbinders in die Abstandsprofile seitliche keilförmige
Auflaufflächen, welche einen zusätzlichen Reibschluß des Linearverbinders mit den ihn
umgebenden Hohlraumwänden der Abstandsprofile erzeugen und damit seinen festen
Sitz nach dem Einbau noch verbessern. Dieser feste Sitz soll gewährleisten, daß sich die
Verbindungsstelle der Abstandsprofile 4, 5 nicht wieder öffnet, bevor der Abstandsprofilrahmen
durch die seitlich auf ihn aufgebrachten Glasscheiben endgültig festgelegt
wird.On the
Wie ersichtlich, erstrecken sich die Seitenrippen 13 nur über einen Teil der gesamten
Höhe H des länglichen Körpers 1, indem sie im Bereich der aus den Keilen 8, 9 und der
Querrippe 6 bestehenden Schneidgratbremse angeordnet sind. Die Seitenrippen weisen,
wie aus Fig. 3 ersichtlich, einen Querschnitt auf, der einem gleichschenkeligen Dreieck
entspricht, dessen Scheitelwinkel 90° beträgt, während die Querrippe 6 ebenfalls einen
dreieckförmigen Querschnitt hat, der ein gleichschenkeliges Dreieck bildet, dessen
Scheitelwinkel von 30° einschließt.As can be seen, the
Die dem Scheibenzwischenraum des Mehrscheibenisolierglases zugewendete Wandung
der Abstandsprofile 4, 5 ist überlichweise mit einer Perforation, also mit Durchbrüchen,
versehen, durch die zwischen dem Hohlraum der Abstandsprofile und dem Scheibenzwischenraum
eine Verbindung hergestellt wird mit dem Ziel, die im Scheibenzwischenraum
befindliche Luft mit Hilfe des in den Hohlraum der Abstandsprofile
eingefüllten Entfeuchtungsmittels, auch Molekularsieb genannt, zu entfeuchten. Die
Oberfläche dieser Unterseite 20 des länglichen Körpers 1 ist, wie in Fig. 2 schematisch
angedeutet, mit einer Riffelung 21 versehen, die beim Hineinschieben des Linearverbinders
in den Hohlraum der Abstandsprofile mit dem Grat der Perforation in Eingriff
tritt und auf diese Weise eine mechanische Verriegelung zwischen Linearverbinder und
Abstandsprofilen bewirkt, die entweder alleinig oder in Verbindung mit anderen
reibungserzeugenden Elementen auf der Oberfläche des Linearverbinders ein
Herausrutschen des Linearverbinders aus dem Abstandsprofilhohlraum bzw. ein Öffnen
des an der Querrippe 6 vorhandenen Spaltes zwischen den gegenüberliegenden
Vorderkanten 15, 16 der beiden Abstandsprofile verhindert.The wall of the
Im übrigen kann die aus der Querrippe 6 und den Keilen 8 und 9 gebildete
Schneidgratbremse entweder auf der Oberseite des länglichen Körpers 1 angeordnet sein,
wie aus Fig. 1 ersichtlich, oder auf der Unterseite 20 liegen, und zwar in Abhängigkeit
von der Schneidgratrichtung der Säge beim Ablängen der Abstandsprofile.Otherwise, the cutting edge brake formed from the transverse rib 6 and the
Der in Fig. 5 dargestellte Linearverbinder besteht ebenfalls aus einem bekannten steifen
Kunststoffmaterial und weist einen nahezu rechteckigen Querschnitt auf. Sein flacher,
länglicher Körper 21 dient zur Verbindung der hohlen Abstandsprofile 24, 25, und wird zu
diesem Zweck wie bei der Ausführungsform nach den Fig. 1 bis 4 mit seinen Teilen 22 bzw.
23 in die beiden Abstandsprofile hineingesteckt, bis die Profilstirnseiten 27 bzw. 28 an dem
Mittenanschlag 26 anstoßen, an dem zu beiden Seiten die sogenante Schneidgratbremse in
Form eines zur Oberkante des Anschlags 6 ansteigenden Keils 220, 221 mit geringem
Abstand vorgelagert ist.The linear connector shown in Fig. 5 also consists of a known rigid plastic material and has an almost rectangular cross section. Its flat,
Die Innenseite 211 des Abstandsprofils 24, 25, das ist also die Profilseite, die dem
Scheibenzwischenraum des Mehrscheibenisolierglases zugewendet ist, bildet üblicherweise
eine perforierte Wandfläche, ist also mit Durchbrüchen 212 versehen, durch die die im
Scheibenzwischenraum befindliche Luft in den Profilhohlraum 222 eindringen kann, um
durch das dort vorhandene Molekularsieb, also einem Feuchtigkeit absorbierenden Mittel,
entfeuchtet zu werden. Diese Durchbrüche 212 werden dadurch hergestellt, daß
beispielsweise mit Hilfe einer Stachelwalze die Hohlprofilwand durchstoßen wird, wobei an
den Durchstoßstellen die Durchbruchränder gewöhnlich einen scharfkantigen Grat bilden,
der in Fig. 5 bei 210 schematisch angedeutet ist.The inside 211 of the
Auf der Bodenseite 29 des länglichen Körpers 21, also auf der Seite des
Linearverbinders, die mit der Innenseite 211 der perforierten Wandfläche der
Abstandsprofile 24, 25 beim Einstecken des Linearverbinders in Berührung tritt, sind
Riffelungen 213, 214 in Form von sich quer zur Längsrichtung des Körpers 1
erstreckenden und in Einsteckrichtung streifenartig mit Abstand hintereinanderliegenden
Rippen 215 angeordnet, die, wie aus Fig. 6 ersichtlich, bei diesem Ausführungsbeispiel
zwei parallele Streifen bilden und so positioniert sind, daß sie im Querschnitt, wie aus
Fig. 5 ersichtlich, ein sägezahnartiges Profil 225 bilden und mit den scharfen Ecken und
Rändern 210 der Durchbrüche 212 in Eingriff treten, wodurch die Haftreibung zwischen
dem Linearverbinder und dem Abstandsprofil gegenüber den herkömmlichen
Konstruktionen, die keine derartigen Riffelungen verwenden, erheblich gesteigert wird,
so daß auf weitere reibungserhöhende Mittel, wie Federn, mechanische Profilverformungen
u. dgl., verzichtet werden kann.On the
Bei dem dargestellten Ausführungsbeispiel wird im Bereich der beiden Längsseiten 216,
217 des Körpers 21 je eine Rippenreihe verwendet, die innerhalb von an sich bekannten
langlochförmigen Materialaussparungen 218, 219 liegt und, wie bei 223 und 224 gezeigt,
Unterbrechungen aufweisen kann, welche durch den Formenbau bedingt sein kann,
indem an diesen Stellen an der Spritzgußform Auswerfer für das Spritzgußteil, also den
Linearverbinder, sitzen.In the illustrated embodiment, in the area of the two long sides 216,
217 of the
Die Tiefe des in Fig. 1 gezeigten sägezahnartigen Profils der Rippen 215 beträgt 0,72
mm, der Rippenabstand ca. 2,5 mm, wobei diese Maße an die jeweils vorhandenen
Perforationsdurchbrüche 212 angepaßt sind.The depth of the sawtooth-like profile of the
Anstelle der beiden streifenartig angeordneten Rippenreihen läßt sich auch nur eine einzige Reihe verwenden, die dann breiter sein kann als eine der dargestellten beiden Reihen und sich auch unter Umständen über die gesamte Breite des Geradverbindes, also seine gesamte Bodenfläche, erstrecken kann.Instead of the two rows of ribs arranged in strips, only one can be used use only one row, which can then be wider than one of the two shown Rows and sometimes under the entire width of the straight connection, so can extend over its entire floor area.
Abmessungen und Lage sowie Größe und Art der Riffelung bzw. der Rippen sind jedenfalls so gewählt, daß das angestrebte Ziel, nämlich einen mechanischen Reibschluß zwischen den Rippenspitzen und den Perforationsdurchbrüchen zu schaffen, erreicht wird.Dimensions and location as well as size and type of corrugation or ribs are at least chosen so that the desired goal, namely a mechanical friction between the tips of the ribs and the perforations becomes.
