Abstract

The screw (5) passes through a hole (4) in a glass panel (2) to fasten it in place and has a screw head (6) in the form of a tapered nut locating in the hole and an adjusting nut (10) which can be screwed into an internal thread (9) of the tapered nut. The shank (7) of the screw is separate from the head and is received in a cup-shaped recess (8) of the head. It has a retaining flange (11) located between the adjusting nut and the base (14) of the recess. Locking members in the form of pegs (16) and grooves (15) fit together with clearances to form a connection which prevents rotation. The clearance between the pegs and grooves gives four degrees of freedom for adjustment. The outside diameter of the flange is smaller than the outside diameter of the adjusting nut.

Description

Die Erfindung betrifft einen Klemmbeschlag für die Befestigung von Glasscheiben mit einer eine Bohrung in der Glasscheibe durchfassenden Klemmschraube, deren Schraubenschaft und Schraubenkopf als getrennte Bauteile ausgebildet sind, wobei der Schraubenschaft gegenüber dem Schraubenkopf senkrecht zur Schraubenschaftachse in vier Freiheitsgraden verstellbar festlegbar ist und der eine Kegelmutter aufweisende Schraubenkopf eine mit einem Innengewinde versehene topfartige Ausnehmung für die Aufnahme des Schraubenschaftes aufweist.The invention relates to a clamp fitting for fastening glass panes with a hole penetrating the glass pane Clamping screw, its screw shaft and screw head as separate Components are formed, the screw shaft compared to the Screw head perpendicular to the screw shaft axis in four degrees of freedom is adjustable and can be fixed with a conical nut Screw head a pot-like recess provided with an internal thread for receiving the screw shaft.

Die Verbindung von Glasscheiben untereinander zu flächendeckenden Glasfronten oder die Befestigung von Glasscheiben an geeigneten Trägerelementen erfolgt regelmäßig über in der Glasscheibe angeordnete Bohrungen. Da die vorgenannten Bohrungen ebenso wie die in sie einfassenden oder sie durchfassenden Befestigungselemente oder Verbindungselemente einer gewissen Fertigungstoleranz unterliegen, besteht regelmäßig die Problematik, die Bohrung in der Glasscheibe mit der Achse des Befestigungselementes oder Klemmelementes in eine fluchtende Deckung zu bringen. Soweit die jeweilige Verbindung zwischen der Glasscheibe und dem Befestigungs- oder Trägerelement dies zuläßt, weicht man hierbei auf das Befestigungs- oder Trägerelement aus, d.h. der erforderliche Toleranzausgleich wird in das Befestigungs- oder Trägerelement gelegt.The connection of glass panes to each other to cover the entire area Glass fronts or the attachment of glass panes to suitable support elements takes place regularly via arranged in the glass pane Holes. Since the aforementioned bores as well as those encasing them or fasteners or fasteners encompassing them subject to a certain manufacturing tolerance, exists regularly the problem, the hole in the glass plate with the axis of the Fastening element or clamping element in an aligned cover bring to. As far as the respective connection between the glass pane and the fastening or carrier element allows this, one softens here the fastener or support member, i.e. the required tolerance compensation is placed in the fastener or support element.

Aus der EP 0 735 227 A2 ist eine Halterung für an Gebäuden anzubringende Platten bekannt, welche eine eine Bohrung in der Platte durchfassende Kegelmutter aufweist, in deren topfartige Ausnehmung ein Schraubeinsatz einschraubbar ist, welches an seinem freien Ende mit einem - ggf. exzentrisch zur Achse des Schraubeinsatzes angeordneten - Befestigungsbolzen oder Gewindestück versehen ist. Mittels der exzentrischen Anordnung des Befestigungsbolzens oder des Gewindestückes gegenüber dem Schraubeinsatz kann ein seitlicher Versatz der beiden vorgenannten Bauteile zueinander erreicht werden. Die Einstellung des erforderlichen seitlichen Versatzes ist damit zwangsläufig mit einer Veränderung der Einschraubtiefe des Schraubeinsatzes verbunden. Ferner sind innerhalb des Schraubeinsatzes eine als Pendelbeschlag wirkende Kugel oder außerhalb des Schraubeinsatzes ein als Pendelbeschlag wirkender Gummiblock vorgesehen, so daß der mit dem Gebäude zu verbindende Befestigungsbolzen gegenüber der Platte eine Pendelbewegung ausführen kann.EP 0 735 227 A2 discloses a holder for attaching to buildings Known plates, which a hole in the plate encompassing Has a tapered nut in its pot-like recess can be screwed in, which at its free end with a - if necessary Eccentric to the axis of the screw insert - fastening bolts or threaded piece is provided. By means of the eccentric Arrangement of the fastening bolt or the threaded piece opposite the screw insert can be offset laterally of the two aforementioned Components can be reached to each other. Setting the required lateral offset is therefore inevitable with a change in the screw-in depth connected to the screw insert. Furthermore, within the Screw insert a ball acting as a pendulum fitting or outside a rubber block acting as a pendulum fitting is provided for the screw insert, so that the fastening bolt to be connected to the building can perform a pendulum movement against the plate.

Aus dem deutschen Gebrauchsmuster 77 05 090 ist ein Klemmbeschlag für Ganzglasanlagen bekannt, bei dem zur Verbindung benachbarter Glasscheiben eine Klemmschiene dient, wobei zur Erzielung eines Toleranzausgleiches in der Klemmschiene entsprechend größere Bohrungen vorgesehen sind, so daß der, der Klemmschraube zugeordneten Mutter ein ausreichendes seitliches Spiel verbleibt.From the German utility model 77 05 090 is a clamp fitting known for all-glass systems, in which for connecting adjacent glass panes a clamping rail is used to achieve tolerance compensation Larger holes are provided in the clamping rail are so that the, assigned to the clamping screw nut sufficient lateral play remains.

Die französische Patentanmeldung 0 617 190 A1 offenbart eine Verbindung zwischen zwei benachbarten Glasscheiben, bei der die Klemmschiene von der Glasscheibe beabstandet angeordnet ist und der Schraubenschaft der Klemmschraube mit einem balligen Kopf in der Klemmschiene gelagert ist.French patent application 0 617 190 A1 discloses a connection between two adjacent glass panes, where the clamping rail is spaced from the glass plate and the screw shaft the clamping screw with a spherical head in the clamping rail is stored.

In ähnlicher Weise löst das US-Patent 4689928 die Problematik des Toleranzausgleiches; hier ist allerdings die ballige Lagerung unmittelbar in die Bohrung in der Scheibe verlegt worden. Zur Erzielung eines wirksamen Toleranzausgleiches ist es hierbei zwingend erforderlich, die an die ballige Lagerung anschließenden Tragelemente entsprechend aufwendig mit zueinander flexiblen Gliedern auszubilden.Similarly, US Patent 4689928 solves the problem of tolerance compensation; here, however, the spherical bearing is directly in the Hole in the disc has been relocated. To achieve effective Tolerance compensation, it is imperative that the crowned Storage subsequent support elements correspondingly expensive with each other to train flexible members.

Einen Toleranzausgleich der Bohrungen zwischen den beabstandeten Platten einer Mehrfach-lsolier-Glasplatte offenbart das deutsche Gebrauchsmuster 93 18 862. Hier sind sowohl in der äußeren als auch in der inneren Glasplatte Bohrungen relativ großen Durchmessers vorgesehen, wobei im Zuge der Montage der die eigentliche Klemmschraube umgebende Bohrungsraum mit Gießharz ausgespritzt wird. Derartig große Bohrungen sind zum einen aus optischen Gründen unerwünscht, zum anderen gestaltet sich die Montage aufgrund der erforderlichen Verwendung von Gießharz entsprechend aufwendig. Tolerance compensation of the holes between the spaced The plates of a multiple insulating glass plate reveal the German utility model 93 18 862. Here are both in the outer and in the inner glass plate holes relatively large diameter provided whereby in the course of assembly the actual clamping screw surrounding Hole space is sprayed with resin. Such large holes are undesirable on the one hand for optical reasons, on the other hand the assembly is based on the required use of Cast resin correspondingly expensive.

Aus der europäischen Patentanmeldung 0 506 522 B1 ist es bekannt, den Toleranzausgleich innerhalb des Bohrloches in der Scheibe durch das Bohrloch teilweise auskleidende und gegeneinander verdrehbare exzentrische Ringe zu bewirken. Auch hier gestaltet sich die Montage aufwendig, weil ein spielfreies Einsetzen der Ringe in das Bohrloch erforderlich ist.From European patent application 0 506 522 B1 it is known that Tolerance compensation within the borehole in the disc through the Borehole partially lining and rotatable eccentric Effect rings. Here, too, the assembly is complex, because it is necessary to insert the rings into the borehole without play.

Aus der EP 0 655 543 A1 ist ein Klemmbeschlag für Glasscheiben bekannt, welcher eine Klemmschraube aufweist, deren Schraubenschaft einen Flansch besitzt, der unter Zwischenschaltung elastischer Stützmittel zwischen einem als Kegelmutter ausgebildeten Schraubenkopf und einer mit dem Schraubenkopf verschraubten Gegenmutter eingespannt ist. Diese Einspannung bildet den Abstützpunkt für die Klemmschraube, so daß der Schraubenschaft gegenüber dem Abstützpunkt eine Pendelbewegung ausführen kann. Eine seitliche Verschiebbarkeit des Schraubenschaftes gegenüber dem Schraubenkopf ist nicht vorgesehen; diese Lösung entspricht somit prinzipiell der kardanischen Abstützung nach dem US-Patent 4689928.A clamp fitting for glass panes is known from EP 0 655 543 A1, which has a clamping screw, the screw shaft has a flange with the interposition of elastic support means between a screw head designed as a taper nut and one is locked with the screw head screwed lock nut. This clamping forms the support point for the clamping screw, see above that the screw shaft has a pendulum movement relative to the support point can execute. Lateral displacement of the screw shaft opposite the screw head is not provided; this solution basically corresponds to the gimbal support after U.S. Patent 4689928.

Aus der EP 0 663 507 A2 ist ferner eine Halterung zur Lagerung einer Platte bekannt, bei der die Bohrung der Glasscheibe ohne Toleranzausgleich von einer Befestigungsschraube durchfaßt wird, die gleichzeitig ein Ankerteil oder ein Aufnahmelager an der Glasscheibe festlegt. Ankerteil bzw. Aufnahmelager sind Bestandteil eines Ausgleichsteils, welches translatorisch oder rotatorisch zueinander bewegliche Bauteile aufweist, so daß eine Anpassung an die erforderliche Position einer weiteren, die eigentliche Verbindung mit einer Unterkonstruktion bewirkenden Halteschraube erfolgen kann. Das zusätzlich zur Befestigungsschraube vorhandene Ausgleichsteil bedingt einen nicht unterschreitbaren Mindestabstand zur Unterkonstruktion und einen entsprechenden baulichen Mehraufwand.From EP 0 663 507 A2 is also a holder for storing a Plate known in which the hole in the glass sheet without tolerance compensation is grasped by a fastening screw, which at the same time Defines anchor part or a receiving bearing on the glass pane. anchor part or receiving bearings are part of a compensating part, which has components that are movable with respect to one another in translation or rotation, so that an adjustment to the required position of another, the actual connection with a substructure effecting retaining screw can be done. The one in addition to the fastening screw Compensating part requires a minimum distance that cannot be undercut for the substructure and a corresponding additional construction effort.

Aufgabe der Erfindung ist es, eine Möglichkeit zur exzentrischen Lagerung einer ein Bohrloch in einer Glasscheibe durchfassenden Klemmschraube zu schaffen, wobei mit geringem baulichen Aufwand und unter einfacher Montage eine genaue Anpassung des Klemmschraubenschaftes an das anzuschließende Träger- oder Verbindungselement erfolgen muß. Die Erfindung zielt insbesondere auf solche Verbindungen ab, bei denen am Trägerelement keine oder keine ausreichende Möglichkeit für einen Toleranzausgleich gegeben ist. Dies ist beispielsweise bei der hängenden Abstützung von Glastüren der Fall, bei denen der Schraubenschaft mit einer Schiebestange verbunden werden muß, d.h. bei denen der Schraubenschaft ohne möglichen Toleranzausgleich in eine Sackbohrung der Schiebestange eingeschraubt wird.The object of the invention is a possibility for eccentric storage a clamping screw encompassing a hole in a glass pane to create, with little construction and under simple Assembly an exact adjustment of the clamping screw shaft to the support or connecting element to be connected must be made. The invention is particularly aimed at those connections where the support element no or insufficient possibility for tolerance compensation given is. This is the case with hanging supports, for example of glass doors, in which the screw shaft with a Push rod must be connected, i.e. where the screw shaft without tolerance compensation in a blind hole in the push rod is screwed in.

Dabei soll weiter gewährleistet sein, daß der Toleranzausgleich in allen senkrecht zur Achse des Schraubenschaftes verlaufenden Ebenen innerhalb der Bohrung in der Glasscheibe möglich ist. Auf zusätzliche Losteile wie exzentrische Klemmringe und dgl. soll verzichtet werden. Insbesondere sollen die für den Toleranzausgleich erforderlichen baulichen Mittel innerhalb der Bohrung in der Glasscheibe angeordnet werden.It should also be ensured that the tolerance compensation in all planes perpendicular to the axis of the screw shaft within the hole in the glass pane is possible. On additional lot parts like eccentric clamping rings and the like should be dispensed with. In particular should be the structural means required for tolerance compensation be arranged within the hole in the glass pane.

Die Erfindung löst die gestellte Aufgabe mit der Lehre nach Anspruch 1.The invention solves this problem with the teaching according to claim 1.

Hiemach ist der Schraubenkopf zweiteilig, nämlich durch eine Kegelmutter und eine in das Innengewinde der Kegelmutter einschraubbare Verstellmutter ausgebildet, wobei zwischen der Kegelmutter und der Verstellmutter miteinander korrespondierende Verriegelungselemente angeordnet sind, die geeignet sind, einen am Schraubenschaft angeordneten Halteflansch zugfest, jedoch in vier Freiheitsgraden verschieblich einzuspannen, wobei die gesamte Klemmvorrichtung innerhalb der Bohrung in der Glasscheibe angeordnet ist. Dies bedingt bei ausreichender Möglichkeit des Toleranzausgleiches einen geringen baulichen Aufwand; insbesondere sind die erfindungsgemäßen Vorteile jedoch nutzbar, wenn nur ein geringer Abstand der Glasscheibe zur angrenzenden Unterkonstruktion oder dgl. gegeben ist.The screw head is therefore in two parts, namely a cone nut and an adjusting nut that can be screwed into the internal thread of the taper nut formed, being between the taper nut and the adjusting nut corresponding locking elements are arranged, which are suitable, a holding flange arranged on the screw shaft tensile, but can be moved in four degrees of freedom, whereby the entire clamping device within the hole in the glass pane is arranged. This requires a sufficient tolerance compensation a low construction effort; in particular are those according to the invention Advantages, however, can be used if only a small distance given the glass pane to the adjacent substructure or the like is.

Weitere Merkmale der Erfindung sind durch die Unteransprüche gekennzeichnet.Further features of the invention are characterized by the subclaims.

Dabei ermöglicht das in vier Freiheitsgraden ausgebildete Spiel zwischen den Verriegelungselementen ein senkrecht zur Achse des Schraubenschaftes gerichtetes Verschieben des Schraubenschaftes gegenüber der Verstellmutter. Der mögliche Verschiebeweg wird noch dadurch begünstigt. daß der Außendurchmesser des Halteflansches kleiner ist als der Außendurchmesser der Verstellmutter sowie zusätzlich dadurch, daß in der topfartigen Ausnehmung im Bereich des Halteflansches eine Freidrehung angeordnet ist, so daß bei entsprechender Ausbildung des Spiels der Halteflansch bis in die vorgenannte Freidrehung eintauchen kann.The game, which is designed in four degrees of freedom, allows between the locking elements perpendicular to the axis of the screw shaft directed displacement of the screw shaft relative to the Adjusting nut. The possible displacement path is further favored by this. that the outer diameter of the retaining flange is smaller than that Outside diameter of the adjusting nut and also in that the pot-like recess in the area of the holding flange a free rotation is arranged so that with appropriate training of the game Retaining flange can immerse into the aforementioned free rotation.

Im einzelnen kann die Verriegelung so ausgebildet sein, daß an der dem Topfboden des Schraubenkopfes zugewandten Seite der Verstellmutter wenigstens zwei, mit Spiel in in dem Halteflansch angeordneten Nuten einfassende Zapfen angeordnet sind.In particular, the lock can be designed so that on the Pot bottom of the screw head facing side of the adjusting nut at least two, with play in grooves arranged in the retaining flange edging pins are arranged.

Um auch bei fest mit der Verstellmutter verschraubtem Schraubenkopf noch eine seitliche Verschiebung des Schraubenschaftes zu ermöglichen, ist vorgesehen, daß die Länge der Zapfen geringfügig größer als die Dicke des Halteflansches ist, so daß bei fest mit der Verstellmutter verschraubtem Schraubenkopf die freien Enden der Zapfen am Topfboden des Schraubenkopfes anliegen, wobei der Halteflansch zwar axial festgelegt, jedoch nicht zwischen Verstellmutter und Topfboden eingeklemmt wird.To even with the screw head firmly screwed to the adjusting nut to allow a lateral shift of the screw shaft, it is intended that the length of the pegs be slightly greater than the thickness of the retaining flange, so that when screwed tightly to the adjusting nut Screw the free ends of the pins on the bottom of the pot Screw head rest, although the retaining flange is fixed axially, but is not caught between the adjusting nut and the base of the pot.

Im Ergebnis wird durch die Maßnahme, daß der Schraubenkopf zweiteilig ausgebildet ist und zwischen den beiden Teilen des Schraubenkopfes der Halteflansch des Schraubenschaftes axial zugfest festlegbar ist, eine baulich einfache Lösung zum Toleranzausgleich innerhalb der Bohrung einer Scheibe geschaffen.As a result, the measure that the screw head in two parts is formed and between the two parts of the screw head Retaining flange of the screw shaft is axially tensile, a structural simple solution for tolerance compensation within the bore of one Disc created.

In der Figur 1 ist ein mit 1 bezeichneter Klemmbeschlag dargestellt, welcher eine Bohrung 4 in einer Glasscheibe 2 durchfaßt und an einer mit 3 bezeichneten Schiebestange festgelegt ist. Bei dem dargestellten Ausführungsbeispiel handelt es sich um eine Glastür, welche über den Klemmbeschlag 1 an der Schiebestange 3 festgelegt ist, die ihrerseits in nicht dargestellter, jedoch bekannter Weise rollend abgestützt ist. Da die Glasscheibe 2 mehrfach über die Klemmbeschläge 1 mit der Schiebestange 3 verbunden und in der Schiebestange 3 ein Toleranzausgleich nicht möglich ist, ist der Toleranzausgleich innerhalb der Bohrung 4 in der Glasscheibe 2 vorgesehen. Zu diesem Zweck findet eine Klemmschraube 5 Verwendung, welche aus einem als Kegelmutter ausgebildeten Schraubenkopf 6 und einem als Verstellschraube dienenden Schraubenschaft 7 besteht. Der Schraubenkopf 6 besitzt eine als Sackbohrung ausgebildete topfartige Ausnehmung 8 mit einem Innengewinde 9. In das Innengewinde 9 ist eine mit 10 bezeichnete Verstellmutter einschraubbar, die ein entsprechendes Außengewinde aufweist.FIG. 1 shows a clamp fitting designated 1, which a bore 4 in a glass pane 2 and one with 3 designated push rod is set. In the illustrated embodiment it is a glass door, which over the clamp fitting 1 on the push rod 3 is fixed, which in turn in a not shown, but is known to be supported on a rolling basis. Because the glass pane 2 several times over the clamp fittings 1 with the push rod 3 connected and a tolerance compensation is not possible in the push rod 3 is the tolerance compensation within the bore 4 in the glass pane 2 intended. A clamping screw 5 is used for this purpose, which consists of a screw head 6 and a screw shaft 7 serving as an adjusting screw. The Screw head 6 has a cup-shaped cup hole Recess 8 with an internal thread 9. In the internal thread 9 is a with 10 designated adjusting nut can be screwed in, which has a corresponding Has external thread.

Der Schraubenschaft 7 besitzt an seinem dem Topfboden 14 zugewandten Ende einen Halteflansch 11, welcher im aufgezeigten Ausführungsbeispiel diametral gegenüberliegende Nuten 15 aufweist. In die Nuten 15 greifen zwei ebenfalls diametral gegenüberliegende Zapfen 16 ein, welche an der Verstellmutter 10 angeordnet und von der Verstellmutter 10 ausgehend gegen den Topfboden 14 gerichtet sind.The screw shaft 7 has on its pot bottom 14 facing End a retaining flange 11, which in the illustrated embodiment has diametrically opposite grooves 15. Grip in the grooves 15 two diametrically opposite pins 16, which on the Adjusting nut 10 arranged and starting from the adjusting nut 10 are directed against the bottom of the pot 14.

Wie aus den Figuren 2 und 3 erkennbar, besteht zwischen den Zapfen 16 und den Nuten 15 ein ausreichendes, mit 12, 12', 12" bezeichnetes Spiel.As can be seen from FIGS. 2 and 3, there is between the pins 16 and the grooves 15 a sufficient game, designated 12, 12 ', 12 ".

Bei der Montage des Klemmbeschlages 1 kann deshalb zunächst die Verstellmutter 10 auf die Klemmschraube 5 aufgesteckt und nach Aufsetzen des mit einem Glasschutz 19 versehenen Anlageflansches 18 der Schraubenschaft 7 in die Sackbohrung 21 über das Gewinde 22 eingeschraubt werden. Anschließend wird der als Kegelmutter ausgebildete Schraubenkopf 6 auf die Verstellmutter 10 aufgeschraubt, wobei die an der Verstellmutter 10 angeordneten, gegen den Topfboden 14 gerichteten Zapfen 16 nach vollständigem Einschrauben des Schraubenkopfes 6 an dem Topfboden 14 anliegen. Da die Länge der Zapfen 16 etwas größer ist als die Dicke des Halteflansches 11, ist auch bei fest angezogenem Schraubenkopf 6 noch ein seitliches Verschieben des Schraubenschaftes 7 senkrecht zur Achse 20 möglich, wenngleich der Halteflansch 11 axial einerseits durch den Topfboden 14 und andererseits durch die Verstellmutter 10 festgelegt ist.When installing the clamp fitting 1, the adjusting nut can therefore be used first 10 placed on the clamping screw 5 and after fitting of the contact flange 18 provided with a glass protection 19 of the screw shaft 7 screwed into the blind bore 21 via the thread 22 become. Then the screw head designed as a taper nut 6 screwed onto the adjusting nut 10, the on the adjusting nut 10 arranged, against the pot bottom 14 pin 16 after screwing the screw head 6 completely into the bottom of the pot 14 concerns. Since the length of the pin 16 is slightly larger than that Thickness of the holding flange 11 is even when the screw head is firmly tightened 6 a lateral displacement of the screw shaft 7 vertically to axis 20 possible, although the retaining flange 11 axially on the one hand through the pot base 14 and on the other hand through the adjusting nut 10 is set.

Der Schraubenkopf 6 ist somit immer zentrisch mit Bezug auf die in der Glasscheibe 2 angeordnete Bohrung 4 festgelegt und stützt sich dabei in bekannter Weise am Klemmring 17 ab.The screw head 6 is thus always centric with respect to that in the Glass pane 2 arranged hole 4 is fixed and is supported in in a known manner from the clamping ring 17.

In der Figur 2 ist die Situation gemäß Figur 1 dargestellt, d.h. die Achse des Schraubenkopfes 6 und die Achse 20 des Schraubenschaftes 7 sind fluchtend angeordnet.FIG. 2 shows the situation according to FIG. 1, i.e. the axis of the screw head 6 and the axis 20 of the screw shaft 7 arranged in alignment.

In der Figur 3 ist eine Situation dargestellt, bei der die Achse 24 der Bohrung 4 (und damit die Achse des Schraubenkopfes 6 bzw. der Verstellmutter 10) von der Achse 20 des Schraubenschaftes 7 (und damit von der Achse 23 der Sackbohrung in der Schiebestange 3) abweicht, so daß unter maximaler Ausnutzung des mit 12, 12', 12" bezeichneten Spiels eine spannungsfreie Verbindung über den Klemmbeschlag 1 unter Ausgleich der Fertigungstoleranzen in der Schiebestange 3 möglich wird. 3 shows a situation in which the axis 24 of the bore 4 (and thus the axis of the screw head 6 or the adjusting nut 10) from the axis 20 of the screw shaft 7 (and thus from the Axis 23 of the blind hole in the push rod 3) deviates so that under maximum utilization of the game designated 12, 12 ', 12 " tension-free connection via the clamp fitting 1 with compensation the manufacturing tolerances in the push rod 3 is possible.
