Definitions
- the invention relates to a closure for releasably holding a grid with cross-sectionally V-shaped lamellae in a lamp housing, with two mirror-image spring arms, each having a hook-shaped shoulder at one free end and which are connected to one another at their opposite end by a crossbar, and so are attached to the lamp housing via this cross-member that the spring arms can be moved transversely to the longitudinal axis of the lamp housing, the outwardly directed hook-shaped shoulders engaging in the grid by notches.
- Such a closure is designed as a bent sheet metal part in which the hook-shaped shoulders have a relatively large extension in the longitudinal direction of the lamp housing. These shoulders grip through a correspondingly large notch in a V-shaped longitudinal web that supports the transverse lamellas and are therefore visible. This is particularly undesirable for grids made of reflective material.
- the invention is therefore based on the object of specifying a closure which is simple to manufacture, assemble and operate and which does not require any changes in visible areas of the grid and is easy to operate.
- each lock is assigned th two notches are located in an upward edge of a transverse lamella, that each spring arm has at its free end a vertically flat head piece that extends parallel to the vertical plane running between the spring arms and has the hook-shaped shoulder, one of which extends after outside contact surface extends obliquely inwards.
- the notches required for the holder thus lie in the upper edge of the transverse slats, which is not visible to the user of the lamp.
- the flat design of the hook-shaped shoulders even makes it possible to apply this closure to the two outermost slats of a grid, which are generally only designed as "half-slats" with only one reflecting side.
- the two closures assigned to these half-slats are then attached to the two end faces of the lamp housing and advantageously have additional stops which project downwards over the head pieces and which facilitate the insertion of the grid.
- the closure 2 which is designed as a one-piece plastic part, is formed symmetrically to the section line II-II and consists of two spring arms 21, 21 'which are connected to one another at their upper end by a crossbar 212 and at a distance therefrom by a spring leg 213.
- each spring arm is equipped with a foot 214, 214 'which extends transversely to the plane E, which runs between the two spring arms and is identical to the plane of the drawing in FIG.
- Each spring arm has a head piece 211 and a stop 215; because of the symmetry to the line II-II, only the spring arm 21 is referred to below.
- Its head piece 211 has a hook-shaped shoulder 2111 which extends outwards in relation to the planes of symmetry and to which one extends from top to bottom and to the plane of symmetry adjoining inclined contact surface 2112. This head piece is flat and extends parallel to the plane E.
- a stop 215 is arranged on the spring arm 21, which projects above the head piece 211 downward.
- the second housing part to be held by the closure is here a mirror grid 1 with transverse slats, of which the last transverse slat 11 is shown. At the top, this has a cross-sectionally U-shaped edge 111 with notches 112 for the head pieces 211.
- the transverse lamella 11 When inserting the mirror grid 1, the transverse lamella 11 is pressed with its notches 112 over the head pieces 211, the stops 215 serving as a guide.
- the spring arms are pressed against one another by the lateral edges of the notches 112 of the transverse lamella 11 which press against the contact surfaces 2112 until the shoulders 2111 reach through the notch and are pressed back into the rest position shown in the figures by the spring leg 213.
- the spring arms must be pressed accordingly until the shoulders 2111 release the transverse lamella.
- the spring arms have recessed grips (at B) which are freely accessible above the adjacent transverse lamella 11 and are at a distance such that they can be gripped with the fingers of one hand.

Abstract
Description
Die Erfindung betrifft einen Verschluß zum lösbaren Haltern eines Rasters mit im Querschnitt V-förmigen Querlamellen in einem Leuchtengehäuse, mit zwei spiegelbildlich ausgeführten Federarmen, die jeweils an einem freien Ende eine hakenförmige Schulter aufweisen und die an ihrem entgegengesetzten Ende durch eine Quertraverse miteinander verbunden und so über diese Quertraverse an dem Leuchtengehäuse befestigt sind, daß die Federarme quer zur Längsachse des Leuchtengehäuses bewegbar sind, wobei die nach außen gerichteten hakenförmigen Schultern durch Ausklinkungen in dem Raster greifen.The invention relates to a closure for releasably holding a grid with cross-sectionally V-shaped lamellae in a lamp housing, with two mirror-image spring arms, each having a hook-shaped shoulder at one free end and which are connected to one another at their opposite end by a crossbar, and so are attached to the lamp housing via this cross-member that the spring arms can be moved transversely to the longitudinal axis of the lamp housing, the outwardly directed hook-shaped shoulders engaging in the grid by notches.
Ein derartiger, in dem DE-Gbm 75 22 065 beschriebener Verschluß ist als Blechbiegeteil ausgebildet, bei dem die hakenförmigen Schultern eine verhältnismäßig große Ausdehnung in Längsrichtung des Leuchtengehäuses haben. Diese Schultern greifen durch entsprechend große Ausklinkungen in einem V-förmigen, die Querlamellen tragenden Längssteg und sind daher sichtbar. Dieser Umstand ist besonders bei Rastern aus spiegelndem Material unerwünscht.Such a closure, described in DE-Gbm 75 22 065, is designed as a bent sheet metal part in which the hook-shaped shoulders have a relatively large extension in the longitudinal direction of the lamp housing. These shoulders grip through a correspondingly large notch in a V-shaped longitudinal web that supports the transverse lamellas and are therefore visible. This is particularly undesirable for grids made of reflective material.
Der Erfindung liegt daher die Aufgabe zugrunde, einen einfach zu fertigenden, zu montierenden und zu bedienenden Verschluß anzugeben, der keine Veränderungen in sichtbaren Flächen des Rasters erfordert-und leicht bedienbar ist.The invention is therefore based on the object of specifying a closure which is simple to manufacture, assemble and operate and which does not require any changes in visible areas of the grid and is easy to operate.
Die erfindungsgemäße Lösung dieser Aufgabe ist dadurch gekennzeichnet, daß sich die jedem Verschluß zugeordneten beiden Ausklinkungen in einem nach oben gerichteten Rand einer Querlamelle befinden, daß jeder Federarm an seinem freien Ende ein in vertikaler Richtung flaches Kopfstück aufweist, das sich parallel zu der zwischen den Federarmen verlaufenden Vertikalebene erstreckt und die hakenförmige Schulter aufweist, von der sich eine nach außen gerichtete Anlauffläche schräg nach innen erstreckt.The inventive solution to this problem is characterized in that each lock is assigned th two notches are located in an upward edge of a transverse lamella, that each spring arm has at its free end a vertically flat head piece that extends parallel to the vertical plane running between the spring arms and has the hook-shaped shoulder, one of which extends after outside contact surface extends obliquely inwards.
Bei der Erfindung liegen somit die für die Halterung erforderlichen Ausklinkungen in dem für den Benutzer der Leuchte nicht sichtbaren oberen Rand der Querlamellen. Die flache Ausbildung der hakenförmigen Schultern ermöglicht es sogar, diesen Verschluß auch bei den beiden äussersten Lamellen eines Rasters anzuwenden, die in der Regel nur als "Halblamellen" mit nur einer spiegelnden Seite ausgebildet sind. Die diesen Halblamellen zugeordneten beiden Verschlüsse sind dann an den beiden Stirnseiten des Leuchtengehäuses angebracht und haben vorteilhafterweise zusätzliche, die Kopfstücke nach unten überragende, Anschläge, die das Einsetzen des Rasters erleichtern.In the invention, the notches required for the holder thus lie in the upper edge of the transverse slats, which is not visible to the user of the lamp. The flat design of the hook-shaped shoulders even makes it possible to apply this closure to the two outermost slats of a grid, which are generally only designed as "half-slats" with only one reflecting side. The two closures assigned to these half-slats are then attached to the two end faces of the lamp housing and advantageously have additional stops which project downwards over the head pieces and which facilitate the insertion of the grid.
Vorzugsweise ist jeder Verschluß als einstückiges Kunststoffteil ausgebildet; um hierbei die erforderliche Rückstellkraft nicht mit entsprechend hohem Materialaufwand erkaufen zu müssen, ist zwischen den beiden Federarmen ein zusätzlicher Federschenkel vorgesehen. Ein Ausführungsbeispiel dieser Art wird.anhand der Figuren näher erläutert; es zeigen
- FIG 1 eine Draufsicht auf einen Verschluß in Verbindung mit einem Raster,
- FIG 2 einen Querschnitt durch die Anordnung nach FIG 1 entlang Linie II-II,
- FIG 3 einen Schnitt entlang Linie III-III in FIG 1 und
- FIG 4 einen Schnitt entlang Linie IV-IV in FIG 1.
- 1 shows a plan view of a closure in connection with a grid,
- 2 shows a cross section through the arrangement according to FIG. 1 along line II-II,
- 3 shows a section along line III-III in FIG. 1 and
- 4 shows a section along line IV-IV in FIG.
Der als einstückiges Kunststoffteil ausgebildete Verschluß 2 ist symmetrisch zur Schnittlinie II-II ausgebildet und besteht aus zwei Federarmen 21, 21', die an ihrem oberen Ende durch eine Quertraverse 212 und im Abstand von dieser durch einen Federschenkel 213 miteinander verbunden sind. Im Bereich der Quertraverse ist jeder Federarm mit einem Fuß 214, 214' ausgerüstet, der sich quer zu der Ebene E erstreckt, die zwischen den beiden Federarmen verläuft und in FIG 1 mit der Zeichenebene identisch ist. Diese Füße dienen zur Befestigung an einem nicht dargestellten Bodenblech des Leuchtengehäuses, das beispielsweise Längsnuten zum Einstecken dieser Füße aufweist: Beim Zusammendrücken der Federarme 21, 21' in Richtung der Pfeile B werden die hierbei um die Längsachse L auftretenden Drehmomente von den Füßen aufgefangen, so daß ein Verdrehen der Federarme vermieden wird. Das erwähnte Drehmoment hat seine Ursache darin, daß der Federschenkel 213 wesentlich schwächer als die Quertraverse 212 ausgebildet ist; ferner kann es durch schräg ansetzende Druckkräfte beim Zusammendrücken der Federarme hervorgerufen oder verstärkt werden.The
Jeder Federarm weist ein Kopfstück 211 und einen Anschlag 215 auf; wegen der Symmetrie zur Linie II-II wird im folgenden nur auf den Federarm 21 Bezug genommen.. Sein Kopfstück 211 hat eine hakenförmige Schulter 2111, die sich bezogen auf die Symmetrieebenen nach außen erstreckt und an die sich eine von oben nach unten und zur Symmetrieebene hin geneigte Anlauffläche 2112 anschließt. Dieses Kopfstück ist flach ausgebildet und erstreckt sich parallel zu der Ebene E.Each spring arm has a
Im Abstand von dem Kopfstück 211 und parallel zu diesem ist an dem Federarm 21 ein Anschlag 215 angeordnet, der das Kopfstück 211 nach unten überragt.At a distance from the
Das durch den Verschluß zu halternde zweite Gehäuseteil ist hier ein Spiegelraster 1 mit Querlamellen, von denen die letzte Querlamelle 11 dargestellt ist. Diese hat oben einen im Querschnitt U-förmigen Rand 111 mit Ausklinkungen 112 für die Kopfstücke 211.The second housing part to be held by the closure is here a
Beim Einsetzen des Spiegelrasters 1 wird die Querlamelle 11 mit ihren Ausklinkungen 112 über die Kopfstücke 211 gedrückt, wobei die Anschläge 215 als Führung dienen. Hierbei werden die Federarme durch die auf die Anlaufflächen 2112 drückenden seitlichen Kanten der Ausklinkungen 112 der Querlamelle 11 gegeneinander gedrückt bis die Schultern 2111 durch die Ausklinkung hindurchgreifen und durch den Federschenkel 213 in die in den Figuren gezeigte Ruhestellung zurückgedrückt werden. Zum Lösen des Spiegelrasters sind die Federarme dementsprechend gegeneinander zu drücken, bis die Schultern 2111 die Querlamelle freigeben. Die Federarme haben hierzu Griffmulden (bei B), die oberhalb der benachbarten Querlamelle 11 frei zugänglich sind und einen solchen Abstand haben, daß sie mit den Fingern einer Hand greifbar sind.When inserting the
