Abstract

The device is especially made of sheet metal (3) with at least one deformation region (14) with a deformation field and connecting bridges with free fields between them. The deformation field is at least partly connected to the surrounding metal plate by the bridges, which are shaped and/or arranged to stretch or change position when pressure is applied to the deformation field, which thus remains protruding from the surrounding metal sheet.

Description

Die vorliegende Erfindung betrifft ein Leuchtengehäuse, in das eine oder mehrere Vertiefungen eingebracht werden sollen.The present invention relates to a lamp housing in which one or more Wells should be introduced.

Das Verformen von Blech spielt in zahlreichen technischen Gebieten eine bedeutende Rolle. So werden Bauteile aus Blech üblicherweise dadurch hergestellt, daß zunächst ein ebenes Blechteil ausgestanzt und anschließend in die gewünschte Form gebracht wird. Dabei werden die Blechteile nicht nur um bestimmte Achsen gefaltet bzw. gebogen, sondern oftmals auch derart verformt, daß Vertiefungen oder Eindellungen gebildet werden.The shaping of sheet metal plays an important role in numerous technical fields Role. So components made of sheet metal are usually made by first flat sheet metal part is punched out and then brought into the desired shape. The sheet metal parts are not only folded or bent around specific axes, but often deformed so that depressions or indentations are formed become.

Ein Anwendungsbeispiel hierfür ist in Fig. 1 dargestellt, die eine Deckeneinbauleuchte 1 im Schnitt zeigt. Das Leuchtengehäuse 2 wird durch eine kastenförmige Blechwanne gebildet, welche an einer (nicht dargestellten) Raumdecke zu befestigen ist. Zur Befestigung der einzelnen Leuchtenelemente innerhalb der Blechwanne 2 werden Befestigungsmittel in Form von Riegelelementen 11 verwendet. An der Unterseite dieser Riegelelemente 11 werden beispielsweise ein Reflektor 5 sowie ein davor angeordneter Diffusor 6 befestigt, an denen wiederum ein Raster 7 sowie die Lampe 8 angeordnet werden. Die Befestigung des Reflektors 5 und des Diffusors 6 in dem Leuchtengehäuse 2 erfolgt dadurch, daß das Riegelelement 11 durch ein Loch in der Bodenseite des Leuchtengehäuses 2 hindurchgeführt und anschließend verdreht und damit arretiert wird.An application example for this is shown in Fig. 1, which is a recessed ceiling light 1 shows in section. The lamp housing 2 is through a box-shaped sheet metal trough formed, which is to be attached to a (not shown) ceiling. to Attachment of the individual lamp elements within the sheet metal tub 2 Fasteners in the form of locking elements 11 are used. On the bottom these locking elements 11 become, for example, a reflector 5 and one in front of it arranged diffuser 6, on which in turn a grid 7 and the lamp 8th to be ordered. The attachment of the reflector 5 and the diffuser 6 in the Luminaire housing 2 takes place in that the locking element 11 through a hole in the Passed through the bottom of the lamp housing 2 and then rotated and so that it is locked.

Wäre die Bodenseite 3 des Leuchtengehäuses 2, in der sich die Löcher für die Riegelelemente 11 befinden, vollkommen eben, hätte diese zur Folge hat, daß die Oberseiten der Riegelelemente 11 über die Bodenseite 3 vorstehen würden. In diesem Fall könnte das Leuchtengehäuse 2 mit den darin bereits montierten Leuchtenelementen nur schlecht verpackt und gestapelt werden. Aus diesem Grund werden in die Bodenseite 3 des Leuchtengehäuses 2 nach innen ragende Vertiefung 4 eingebracht, deren Bodenseiten die Löcher für die Riegelelemente 11 enthalten, so daß diese nicht mehr hervorstehen.Would be the bottom 3 of the lamp housing 2, in which the holes for the Bolt elements 11 are completely flat, would have the consequence that the The upper sides of the locking elements 11 would protrude beyond the bottom side 3. In this Case could be the lamp housing 2 with the lamp elements already mounted therein poorly packed and stacked. For this reason, in the Bottom side 3 of the luminaire housing 2, recess 4 projecting inwards, whose bottom sides contain the holes for the locking elements 11 so that they do not stand out more.

Das Einbringen solcher Vertiefungen in ein ebenes Blech erfordert besondere Stanzprägewerkzeuge, welche in der Anschaffung äußerst teuer sind. Der Grund hierfür liegt darin, daß beachtliche Kräfte aufgebracht werden müssen, um eine Vertiefung genügender Höhe in ein ebenes Blech einzuformen, ohne dabei die umgebenden Bereiche des Blechs zu beeinflussen oder sogar zu zerstören. Neben den hohen Kosten besteht eine weitere Schwierigkeit darin, daß bei einem bestimmten Stanzprägewerkzeug die Tiefe und Form der Vertiefung vorgegeben ist, d.h., mit einem bestimmten Werkzeug kann auch nur eine bestimmte Vertiefung hergestellt werden.The introduction of such depressions in a flat sheet metal requires special Punching dies, which are extremely expensive to buy. The reason for that lies in the fact that considerable forces have to be applied in order to deepen them of sufficient height in a flat sheet metal, without the surrounding To influence or even destroy areas of the sheet. In addition to the high costs Another difficulty is that with a particular Stamping tool the depth and shape of the recess is specified, i.e. with a certain tools, only a certain recess can be made.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die Verformung an Blechteilen zur Bildung von Vertiefungen einfacher und flexibler zu gestalten.The present invention is therefore based on the object of the deformation To make sheet metal parts easier and more flexible to form recesses.

Diese Aufgabe wird durch ein Leuchtengehäuse gemäß Anspruch 1 gelöst.This object is achieved by a lamp housing according to claim 1.

Das erfindungsgemäße Leuchtengehäuse weist mindestens einen Ausformungsbereich auf, der aus einem Verformungsfeld und mehreren Verbindungsstegen, zwischen denen sich Freifelder befinden, besteht, wobei das Verformungsfeld zumindest teilweise über die Verbindungsstege mit dem umgebenden Metallblech verbunden ist. Die Verbindungsstege verlaufen dabei derart oder sind so geformt, daß sie sich bei Druck auf das Verformungsfeld strecken oder in ihrer Position verändern, so daß in Folge davon das Verformungsfeld bleibend aus dem umgebenden Metallblech heraustritt.The luminaire housing according to the invention has at least one shaping area that consists of a deformation field and several connecting webs between which there are free fields, with the deformation field at least partially over the connecting webs are connected to the surrounding metal sheet. The Connecting webs run in this way or are shaped so that they are under pressure stretch on the deformation field or change its position, so that in succession of which the deformation field permanently emerges from the surrounding metal sheet.

Bei dem erfindungsgemäßen Leuchtengehäuse wird der Aufwand zum Verformen des Ausformungsbereichs gegenüber dem umgebenden Bereich deutlich reduziert, da lediglich die Verbindungsstege gestreckt und /oder verbogen werden müssen. Die hierfür benötigten Kräfte sind allerdings deutlich niedriger als bei einem Verformen eines vollständig geschlossenen Blechs. Ein weiterer Vorteil besteht darin, daß je nach Form und Anordnung des Ausformungsbereichs verschiedene Formen und Tiefen für die in das Blechteil einzubringende Vertiefung realisiert werden können, ohne daß hierfür jeweils ein eigenes Stanzprägewerkzeug verwendet werden muß.In the luminaire housing according to the invention, the effort for deforming the Forming area significantly reduced compared to the surrounding area, because only the connecting webs have to be stretched and / or bent. The the forces required for this are, however, significantly lower than in the case of deformation of a completely closed sheet. Another advantage is that depending on Shape and arrangement of the molding area different shapes and depths for the depression to be introduced into the sheet metal part can be realized without a separate stamping die must be used for this.

Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Developments of the invention are the subject of the dependent claims.

So sind die Verbindungsstege vorzugsweise konkav oder konvex gekrümmt. Alternativ dazu können aber beispielsweise auch S-förmige oder andere nicht-gerade Formen verwendet werden. Um ferner eine möglichst gleichmäßige Kraftverteilung zu erzielen, sind die Verbindungsstege vorzugsweise gleichmäßig verteilt und/oder jeweils zwei benachbarte Verbindungsstege symmetrisch zueinander angeordnet.The connecting webs are preferably curved in a concave or convex manner. alternative this can also be done, for example, with S-shaped or other non-straight shapes be used. In order to achieve a force distribution that is as even as possible, the connecting webs are preferably evenly distributed and / or two each Adjacent connecting webs are arranged symmetrically to one another.

Die in Fig. 1 dargestellte Leuchte 1 mit der in die Bodenseite 3 des Leuchtengehäuses 2 eingebrachten Vertiefung 4 wurde bereits oben erläutert. Im folgenden soll nunmehr das in Fig. 2 dargestellte Blechteil 12, welches zur Bildung des Leuchtengehäuses 2 verwendet wird, näher erläutert werden.The lamp 1 shown in FIG. 1 with the bottom 3 of the lamp housing 2 introduced recess 4 has already been explained above. In the following, the 2, which is used to form the luminaire housing 2 is used to be explained in more detail.

Das in Fig. 2 dargestellte ebene Blechteil 12 wird aus einem einzigen ebenen Blech gestanzt und anschließend in die kastenförmige Struktur zur Bildung eines Leuchtengehäuses verformt. Dabei werden die vier um die Bodenseite 3 herum angeordneten Seitenbereiche 13 nach unten gebogen, so daß sich die in Fig. 1 dargestellte Struktur ergibt. Dieses Verbiegen der Seitenteile 13 ist mit einem verhältnismäßig niedrigem Kraftaufwand möglich. Darüber hinaus werden zwei Ausformungsbereiche 14 gegenüber der Bodenseite 3 verformt, um die beiden nach innen ragenden Vertiefungen 4 zu bilden, die zur Aufnahme der Riegelelemente 11 zur Befestigung der Leuchtenelemente in dem Gehäuse 2 vorgesehen sind.The flat sheet metal part 12 shown in FIG. 2 is made from a single flat sheet metal punched and then into the box-shaped structure to form a Luminaire housing deformed. The four around the bottom 3 arranged side areas 13 bent downward so that the in Fig. 1st structure shown results. This bending of the side parts 13 is with a relatively low effort possible. In addition, two Forming areas 14 deformed relative to the bottom 3 to the two after to form internally projecting recesses 4 for receiving the locking elements 11 for Attachment of the lamp elements are provided in the housing 2.

Einer der beiden Ausformungsbereiche 14 ist vergrößert in Fig. 3 dargestellt. Es besteht aus einem kreisförmigen mittleren Verformungsfeld 15, sowie aus mehreren das Verformungsfeld 15 mit dem umgebenden Bereich der Bodenseite 3 verbindenden Verbindungsstegen 16, und 17, zwischen denen Freifelder 18 und 19 angeordnet sind. Das Einbringen der Freifelder 18, 19 zum Bilden der Verbindungssteg 16, 17 erfolgt bereits während des Ausstanzens des Blechteils 12.One of the two shaping regions 14 is shown enlarged in FIG. 3. It exists from a circular central deformation field 15, as well as from several Deformation field 15 connecting with the surrounding area of the bottom side 3 Crosspieces 16 and 17, between which free fields 18 and 19 are arranged. The free fields 18, 19 are introduced to form the connecting web 16, 17 already during the punching out of the sheet metal part 12.

Die Verbindungsstege 16, 17 sind jeweils konkav oder konvex gekrümmt, wobei jeweils zwei benachbarte Verbindungsstege 16, 17 symmetrisch zueinander angeordnet sind. Dies hat den Vorteil, daß bei Druckausübung auf das Verformungsfeld 15 eine gleichmäßige Kraftverteilung auf die Verbindungsstege 16, 17 erzielt wird. In die Mitte des Verformungsfelds 15 ist ferner ein Loch 20 eingestanzt, durch welches das in Fig. 1 dargestellte Verriegelungselement 11 hindurchgeführt werden kann.The connecting webs 16, 17 are each concave or convex curved, wherein each two adjacent connecting webs 16, 17 arranged symmetrically to each other are. This has the advantage that when pressure is exerted on the deformation field 15 a uniform force distribution on the connecting webs 16, 17 is achieved. In the center of the deformation field 15 is also punched a hole 20 through which the in Fig. 1st locking element 11 shown can be passed.

Die Vertiefung 4 wird dadurch gebildet, daß auf das Verformungsfeld 15 Druck ausgeübt wird, so daß dieses aus der durch die Bodenseite 3 gebildeten Ursprungsebene herausgehoben wird. Hierbei werden die Verbindungsstege 16 und 17 je nach Tiefe der Vertiefung um ihre gekrümmten Bereiche 16a bzw. 17a längs gestreckt. Die hierfür notwendige Kraft ist deutlich niedriger als das Einbringen einer Vertiefung in ein geschlossenes Blech.The recess 4 is formed in that 15 pressure on the deformation field is exercised so that this from the plane of origin formed by the bottom side 3 is lifted out. Here, the connecting webs 16 and 17 depending on the depth of the Recess stretched longitudinally around their curved regions 16a and 17a. The one for this necessary force is significantly lower than the insertion of a depression in one closed sheet.

An den Endbereichen, an denen die zwei Verbindungssteg 16, 17 wieder zusammenlaufen, sind ferner kleine Einkerbungen 20 vorgesehen, die bewirken, daß bei einer Längsstreckung der Verbindungsstege 16, 17 keine zusätzlichen Verformungen in diesen Endbereichen auftreten. Hierdurch wir zum einen der Kraftaufwand reduziert, zum anderen ist die Gefahr, daß die Verbindungsstege 16, 17 brechen oder reißen, geringer.At the end areas where the two connecting webs 16, 17 again converge, small notches 20 are also provided, which cause a longitudinal extension of the connecting webs 16, 17 no additional deformations in occur in these end areas. On the one hand, this reduces the effort, on the other hand there is the risk that the connecting webs 16, 17 break or tear, lower.

Anstelle der in Fig. 3 dargestellten konkav bzw. konvex gekrümmten Verbindungsstege können auch andere Strukturen verwendet werden. Beispielsweise wäre auch die Verwendung von abgewinkelten oder S-förmigen Verbindungsstegen denkbar. Darüber hinaus ist es nicht notwendig, daß alle Verbindungsstege gleichartig ausgestaltet sind. Soll beispielsweise das Verformungsfeld nicht in eine zur Ursprungsebene parallele sondern in eine geneigte Ebene verformt werden, so können die Verbindungsstege an der Seite der Vertiefung, die eine größere Tiefe aufweisen soll, länger sein. Auch kann der Verformungsbereich anstelle einer Kreisform eine beliebige Form annehmen. Ferner wäre auch denkbar, daß das Verformungsfeld an einer Seite unmittelbar mit dem umgebenden Bereich der Bodenseite verbunden ist, so daß das Verformungsfeld lediglich gegenüber der Bodenseite verbogen wird.Instead of the concave or convex curved connecting webs shown in FIG. 3 other structures can be used. For example, that would also be Use of angled or S-shaped connecting bars is conceivable. About that furthermore, it is not necessary for all the connecting webs to be of the same design. For example, the deformation field should not be in a parallel to the original plane but are deformed into an inclined plane, the connecting webs can the side of the recess that is to have a greater depth is longer. Can too the deformation area takes any shape instead of a circular shape. It would also be conceivable that the deformation field on one side directly with the surrounding area of the bottom side is connected, so that the deformation field is only bent towards the bottom side.

Eine weitere Möglichkeit für einen erfindungsgemäßen Ausformungsbereich 14 ist in Fig. 4 dargestellt. Bei dieser Variante sind die Verbindungsstege 16 gerade und verbinden das Verformungsfeld 15 in nicht-radialer Weise mit dem umgebenden Bereich der Bodenseite 3. Wird in diesem Fall Druck auf das Verformungsfeld 15 ausgeübt, so verändern die Verbindungsstege 16 derart ihre Position, daß das Verformungsfeld 15 aus der Ursprungsebene unter einer leichten Rotationsbewegung heraustritt.Another possibility for a shaping region 14 according to the invention is shown in FIG Fig. 4 shown. In this variant, the connecting webs 16 are straight and connect the deformation field 15 in a non-radial manner to the surrounding one Area of the bottom side 3. In this case, pressure is applied to the deformation field 15 exercised, the connecting webs 16 change their position such that the Deformation field 15 from the original plane with a slight rotational movement emerges.

Bei dem erfindungsgemäßen Leuchtengehäuse wird somit der Aufwand zum Verformen des Blechs zum Bilden von Vertiefungen derart reduziert, daß die in ihrer Anschaffung sehr teuren Stanzprägewerkzeuge nicht mehr notwendig sind. Darüber hinaus können die Vertiefungen in ihrer Form und Struktur flexibel gestaltet werden.In the luminaire housing according to the invention, the effort for deforming is thus reduced of the sheet for forming depressions reduced so that the purchase very expensive stamping dies are no longer necessary. In addition, you can the shape and structure of the recesses are flexible.
