Description

mit dem ersten Winkelschenkel an einer Deckplatte des Tragrahmens angeordnete Blattfeder gebildet ist, die am freien Endbereich des zweiten Winkelschenkels mit einer in die Randrillung einrastenden, rohrartigen, offenen Rollung ausgestattet ist, wobei jedes Verschlußglied im ersten Rahmenbereich in seiner Biegeverformung durch einen an ihm und/oder am Tragrahmen vorgesehenen Begrenzungsanschlag begrenzt ist und jedes Verschlußglied im zweiten Rahmenbereich mit Hilfe der Stellschraube etwa in Richtung auf den Lippenrand verschieblich gelagert istis formed with the first angle leg arranged on a cover plate of the support frame leaf spring, which on the free end area of the second angle leg with a tubular, open rolling is equipped, each closure member in the first frame area in its bending deformation is limited by a limit stop provided on it and / or on the support frame and each locking member in the second frame area with the help of the adjusting screw approximately in the direction of the The edge of the lip is displaceably mounted

Die als Blattfedern ausgebildeten Verschlußglieder weichen beim Einschieben aufgrund des Zusammentreffens der Rollung mit dem Lippenrand radial nach außen und schnappen anschließend elastisch in den Lippenrand ein, wodurch dann eine formschlüssige Verankerung gegeben ist Sofern die Stellschraube noch nicht gaüz zugestellt ist, ist der Fonnglaskörper innerhalb der Befestigungeinrichtung noch veränderbar gehalten, was insbesondere für Einstellarbeiten vorteilhaft ist Je nach Stellung der Stellschraube kann der Formglaskörper auch unter gleichzeitiger ZurQckbiegung der Verschlußglieder wieder aus der Verankerung herausgenommen werden, um z. B. bei einem handgefertigten Formglaskörper zu überprüfen, ob der Lippenrand an den den Verschlußgliedern zugeordneten Stellen eine sichere Verankerung ermöglicht Die als Blattfedern ausgebildeten Verschlußglieder weichen dabei elastisch radial nach außen zurück.The closing elements, which are designed as leaf springs, give way when they are pushed in due to the coincidence the curl with the lip edge radially outwards and then snap elastically into the lip edge a, which then gives a positive anchoring If the set screw is not yet is completely delivered, the mold glass body is within the Fastening device still kept changeable, which is particularly advantageous for adjustment work Depending on The molded glass body can also position the adjusting screw while simultaneously bending the locking elements back can be removed from the anchorage again to z. B. with a handmade molded glass body to check whether the lip edge is secure at the points assigned to the closure members Anchoring is made possible. The closure members, which are designed as leaf springs, give way elastically and radially back to the outside.

Soll der Formglaskörper endgültig in der Befestigungseinrichtung festgelegt werden, so genügt es die eine vorhandene Stellschraube so weit zuzustellen, daß die Verschlußglieder mit ihrer Rollung mit leichtem Druck in der umlaufenden Rille des Lippenrandes anliegen. In diesem Fall werden die Verschlußglieder im ersten Rahmenbereich an die jeweiligen Anschläge angedrückt wodurch auch ein unfreiwilliges Ausrasten des Formglaskörpers aus der Befestigungseinrichtung verhindert ist. Die rohrartige, offene Rollung der Verschlußglieder erleichtert die Wasserabfuhr im Bereich des Lippenrandes, da daß Wasser ungehindert hindurchfließen kann. Dies ist vor allem wichtig bei einer Montage von mit derartigen Formglaskörpern ausgestatteten Leuchten an der senkrechten Wand.If the molded glass body is to be finally fixed in the fastening device, it is sufficient to deliver an existing set screw so far that the locking members with their rolling with easy Apply pressure in the circumferential groove of the lip edge. In this case, the locking members in first frame area pressed against the respective stops, which also causes an involuntary disengagement the molded glass body is prevented from the fastening device. The tubular, open curl of the Closure elements facilitate the drainage of water in the area of the lip edge, since that water is unhindered can flow through. This is particularly important when assembling molded glass bodies of this type equipped lights on the vertical wall.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der "Zeichnung näher erläutert. Fs zeigtAn exemplary embodiment of the invention is explained in more detail below with reference to the "drawing. Fs shows

F i g. 1 eine schematische Seitenansicht einer Befestigungseinrichtung für Leuchtenhohlglas undF i g. 1 is a schematic side view of a fastening device for hollow glass luminaires and

Fig.2 einen Schnitt durch die Befestigungseinrichtung gemäß F i g. 1 längs der Linie H-II.2 shows a section through the fastening device according to FIG. 1 along the line H-II.

In der Zeichnung ist als Formglaskörper eine Leuchtenschale 1 (in F i g. 1 nur strichpunktiert angedeutet) dargestellt, die einen einrilligen Lippenrand la aufweist. Die Befestigungseinrichtung besteht aus einem wahlweise an einer Wand oder einer sonstigen Stützfläche befestigbaren Tragrahmen 2 für den Lippenrand la der Leuchtenschale 1 und weist an wenigstens zwei einander gegenüberliegenden Randbereichen 2a, 2b gegen den Lippenrand la elastisch vorspannbare und in dessen Rillung einrastbare Verschlußglieder 3, 4 auf. Der Rahmen 2 ist mit einer Deckplatte 2c ausgebildet, an der die Verschlußglieder 3 befestigt sind und das Verschlußglied 4 etwas parallel zur Vorspannrichtung bezüglich des Lippenrandes la verschieblich gelagert sowie durch eine von der Außenseite des Rahmens 2 zugängliche Stellschraube 5 verstellbar istIn the drawing, a lamp shell 1 (only indicated by dash-dotted lines in FIG. 1) is shown as a molded glass body, which has a single-groove lip edge la. The fastening device consists of a support frame 2 for the lip rim la of the lamp shell 1, which can be optionally attached to a wall or other supporting surface, and has closure members 3, 4 that can be elastically pretensioned against the lip rim la and snap into its grooves on at least two opposite edge regions 2a, 2b . The frame 2 is formed with a cover plate 2c, to which the closure members 3 are attached and the closure member 4 is mounted displaceably somewhat parallel to the pretensioning direction with respect to the lip edge la and is adjustable by an adjusting screw 5 accessible from the outside of the frame 2

Wie insbesondere der Fig.2 entnommen werden kann, bestehen die Verschlußglieder 3, 4 jeweils aus einer etwa rechtwinklig gebogenen Blattfeder, die mit dem ersten Winkelschenkel an der Deckplatte 2c des Rahmens 2 befestigt bzw. verschieblich gelagert und im freien Endbereich des zweiten Winkelschenkels mit einer in den Lippenrand la einrastbaren Roilung ausgebildet vorzugsweise offen angerollt istAs can be seen in particular from FIG. 2, the closure members 3, 4 each consist of an approximately right-angled leaf spring, which is fastened or slidably mounted with the first angle leg on the cover plate 2c of the frame 2 and in the free end region of the second angle leg with a formed in the lip edge la latchable roll is preferably rolled open

Die Verschlußglieder 3 im ersten Rahmenbereich 2a sind durch den Lippenrand la im Sinne einer Ausweichbewegung biegeverformbar angeordnet, jedoch im Bewegungsbereich durch Anschläge 2d, 3a begrenzt welch letztere am Federmaterial und/oder am Rahmen 2 angeordnet bzw. ausgebildet sind.The closure members 3 in the first frame area 2a are arranged so that they can be deformed by the lip edge la in the sense of an evasive movement, but limited in the movement area by stops 2d, 3a, the latter being arranged or formed on the spring material and / or on the frame 2.

Die Stellschraube 5 ist am Rahmen 2 parallel zur Schieberichtung des zugeordneten Verschlußgliedes 4 gewindegängig gelagert, mit dem letzteren etwa im mittleren Längenbereich des zweiten Winkelschenkels axiaJ schiebefest drehbar verbunden und mit einem verbreiterten Schraubenkopf 5a ausgebildet, der den Stellbereich der Schraube und demzufolge auch den Verschiebungsbereich des Verschlußglieds 4 in Richtung zum Lippenrand la auf eine bestimmte Größenordnung begrenztThe adjusting screw 5 is threadedly mounted on the frame 2 parallel to the sliding direction of the associated closure member 4, is axially connected to the latter so that it cannot slide in approximately the middle length range of the second angle leg and is designed with a widened screw head 5a , which controls the adjusting range of the screw and consequently also the displacement range of the Closure member 4 is limited in the direction of the lip edge la to a certain order of magnitude

Der Rahmen 2 bzw. dessen Deckplatte Ic ist für das Verschlußgiied 4 mit einer Schiebeführung 2e ausgestattet bzw. ausgebildet, der ein Nietbolzen 2e' zugeordnet ist. Dieser durchsetzt ein Langloch im ersten Winkelschenkel des Verschlußglieds 4 verschieblich und hält das letztere mit einem verbreiterten Bolzenkopf im Gleitsitz an der Deckplatte 2c. Der Nielbolzen 2e' begrenzt außerdem den Verschiebungsbereich des Verschlußglieds 4 zusätzlich.The frame 2 or its cover plate Ic is equipped or designed for the closure member 4 with a sliding guide 2e to which a rivet bolt 2e 'is assigned. This slidably penetrates an elongated hole in the first angle leg of the closure member 4 and holds the latter with a widened bolt head in a sliding fit on the cover plate 2c. The Nielbolzen 2e 'also limits the range of displacement of the closure member 4 in addition.

Die Begrenzungen der Verschiebungs- bzw. Stellbereiche des Verschlußglieds 4 und der Schraube 5 sind derart gewählt, daß der zweite Winkelschenkel des Verschlußgliedes 4 am lippenrandseitigen Ende des Verschiebungs- bzw. Stellbereichs gemäß der F i g. 2 sowohl einen Abstand vom Lippenrand la aufweist bzw. höchstens am letzteren drucklos anliegt und lediglich die Rollung am freien Endbereich des zweiten Winkelschenkels in die Rillung des Lippenrands la, vorzugsweise im Klemmsitz aufgrund der offenen Anrollung, eingerastet ist.The limits of the displacement or setting ranges the closure member 4 and the screw 5 are chosen such that the second angle leg of the Closure member 4 at the lip edge-side end of the displacement or adjustment area according to FIG. 2 both has a distance from the lip edge la or at most rests on the latter without pressure and only the Rolling at the free end area of the second angle leg into the grooves of the lip edge la, preferably is locked in a press fit due to the open curl.

Um ein zentriertes Einführen des Lippenrands la in den Rahmen 2 zu erleichtern, können am letzteren den Einrastweg des Lippenrands la bestimmende Rippen 2f angeordnet bzw. ausgebildet sein, die vorzugsweise gegen die Einrastrichtung keilförmig verjüngt sind.In order to facilitate a centered insertion of the lip rim la into the frame 2, ribs 2f which determine the latching path of the lip rim la can be arranged or formed on the latter, which are preferably tapered in a wedge-shaped manner against the latching direction.

Für einen Formglaskörper mit wenigstens zwei Rillen des Lippenrands könnten die Verschlußglieder auch in die körperfernste Randrille einrasten. Ebenso könnte es bei einer Befestigungseinrichtung für das Leuchtenhohlglas einer Segmentleuchte vorteilhaft sein, die Rippen 2/ des Rahmens 2 entweder gänzlich wegzulassen oder derart anzuordnen, daß die einzelnen Hohlglaskörpersegmente querachsig zu den Stellschrauben 5 justierbar sind. Weiterhin wäre es denkbar, das mittels der Stellschraube 5 bewegbare Verschlußglied 4 in der vorher beschriebenen Ausbildung als gebogene Blattfeder mit dem ersten Winkelschenkel nicht verschieblich, sondern fest am Rahmen 2 bzw. dessen Deckplatte 2c anzuordnen und gleichfalls durch elastische Biegeverformung mittels der Stellschraube 5 auf dem durch die letztere begrenzten Bewegungsbereich gegen den Lippenrand la des Formglaskörpers 1 vorzuspannen.For a molded glass body with at least two grooves on the lip edge, the closure members could also be in engage the furthest edge groove. The same could be the case with a fastening device for the hollow lamp glass a segment lamp be advantageous to either omit the ribs 2 / of the frame 2 entirely or to be arranged in such a way that the individual hollow glass body segments can be adjusted transversely to the adjusting screws 5 are. Furthermore, it would be conceivable that by means of the adjusting screw 5 movable closure member 4 in the previously described training as a curved leaf spring with the first angle leg not displaceable, but to be fixed to the frame 2 or its cover plate 2c and likewise by elastic bending deformation by means of the adjusting screw 5 on the range of motion limited by the latter against the Tension the lip edge la of the molded glass body 1.

5. Fastening device according to claim 4, characterized in that the ribs (21) are tapered in a wedge shape against the locking direction of the lip edge (la).

6. Fastening device according to claim 1, characterized in that the frame for Receiving an at least two-groove lip edge of the molded glass body is dimensioned, the Snap the locking links into the furthest edge groove.

The invention relates to a fastening device for molded glass bodies, in particular hollow glass for lamps with an outer lip edge, consisting of a support frame for at least one on a first Frame area arranged, designed as a leaf spring and with a curl elastically behind the lip edge engaging the edge groove, at least that of a second frame area arranged approximately opposite the first one with the help of an adjustable screw accessible from the outside of the support frame at its distance from the is associated with another locking member variable locking member.

From US-PS 18 10 520 a fastening device of the type just mentioned is known to hold a lamp hollow glass or a cover screen, it has a total of three locking members that are distributed over the circumference of the circular support frame. Two of these locking members are predominantly solid attached, while the third closure member in its distance to the other closure members It consists of a metal strip that is attached to the inside of the support frame via a limited part of the circumference extends and is riveted at its ends to the support frame Opposite the center of the strip, the set screw is provided in the support frame, which is then inserted into the interior of the support frame can be screwed in that the metal strip from its resting on the support frame Position is bent inwards.

When installing the cover screen or the hollow glass luminaire, it is therefore necessary to use the Turn back the adjusting screw in order to bring the metal strip into its starting position. Only in this one Position, the hollow glass luminaire can be inserted into the support frame. Then the adjusting screw be screwed back in, whereupon the metal strip bends inward and after enough long rotation of the adjusting screw in contact with the lip edge of the mounted hollow glass comes.

The disadvantage of the known fastening device is that it occurs during the assembly of the lamp hollow glass it is necessary to hold the same after introduction into the support frame until the inside The screwed adjusting screw creates the necessary form-fitting anchoring of the luminaire glass. Thereafter the luminaire glass can now be removed from the support frame, provided that the adjusting screw also is screwed back again.

Another disadvantage of the known fastening device is that the metal strip rests tangentially on the lip edge, whereby the water drainage from the lip edge in can be undesirably disturbed. This is especially critical if the hollow glass of the luminaire is on to be attached to a vertical wall, where the unobstructed through the adjacent metal strip Water drainage from the lip edge is somewhat obstructed.

The invention is therefore based on the object of providing a fastening device of the type mentioned at the beginning Art to create, with the help of which even heavy and misshapen molded glass body is held quickly and safely can be and with the possibility of the irregular shaped glass body Alignment is given.

This object is achieved in that each closure member is bent approximately at right angles.
