Description

Titel: BodentürschließerTitle: Floor door closer
Beschreibungdescription
Die Erfindung betrifft einen Bodentürschließer mit einem Gehäuse zur Aufnahme eines Schließmechanismusses, wobei das Gehäuse von einem Gehäusedeckel abgedeckt ist, der eine eine Tür oder dergleichen tragende Achse des Schließmechanismusses lagert.The invention relates to a floor door closer with a housing for receiving a locking mechanism, the housing being covered by a housing cover which supports an axis of the locking mechanism which carries a door or the like.
Solche Bodentürschließer sind hinlänglich bekannt. Sie weisen ein Gehäuse auf, in dem der eigentliche Schließmechanismus des Türschließers untergebracht ist. Aus dem Gehäuse erstreckt sich eine Achse nach außen, welche eine zu betätigende Tür oder dergleichen lagert. Das Gehäuse ist mit einem Gehäusedeckel verschließbar, welcher vorzugsweise über Schrauben mit dem Gehäuse verbindbar ist und welcher die Achse lagert. Ein solcher Gehäusedeckel ist z. B. in der DE 295 01 929.8 U1 dargestellt.Such floor closers are well known. They have a housing in which the actual closing mechanism of the door closer is housed. An axis extends out of the housing and supports a door or the like to be operated. The housing can be closed with a housing cover, which can preferably be connected to the housing via screws and which supports the axle. Such a housing cover is such. B. in DE 295 01 929.8 U1.
Eine allgemeine Forderung bei der Ausbildung von Bodentürschließern besteht darin, dass das Gehäuse möglichst flach ausgebildet sein soll. Um diese Forderung zu erfüllen, wird ein Bodentürschließer mit zwei Federn verwendet. Dies wiederum bedingt jedoch, dass für die Achse, welche die Tür oder dergleichen lagert, in dem Bodentürschließer ein größeres Loch in dem Gehäusedeckel vorgesehen sein muss. Dadurch nimmt die Steifig- keit des Gehäusedeckels als Ganzes ab und es kann durch Verformungen des Gehäusedeckels zu Problemen beim Betrieb des Bodentürschließers kommen.A general requirement when designing floor door closers is that the housing should be as flat as possible. To meet this requirement, a floor spring with two springs is used. However, this in turn means that a larger hole in the housing cover must be provided in the bottom door closer for the axle that supports the door or the like. As a result, the rigidity of the housing cover as a whole decreases and deformations of the housing cover can lead to problems when operating the floor closer.
Es ist daher Aufgabe der vorliegenden Erfindung, einen Bodentürschließer zu schaffen, der trotz einer flachen Bauweise einen problemlosen Betrieb gewährleistet. Diese Aufgabe wird bei einem Bodentürschließer der eingangs erläuterten Art dadurch gelöst, dass der Gehäusedeckel an mindestens einem Randbereich eine Versteifungsschulter aufweist.It is therefore an object of the present invention to provide a floor door closer which, despite a flat design, ensures problem-free operation. This object is achieved in a floor closer of the type described at the outset in that the housing cover has a stiffening shoulder on at least one edge region.
Durch die erfindungsgemäße Versteifungsschulter wird gewährleistet, dass sich der Gehäusedeckel auch bei einer relativ flachen Ausgestaltung nicht verformt, so dass jederzeit ein problemloser Betrieb der Tür oder dergleichen möglich ist.The stiffening shoulder according to the invention ensures that the housing cover does not deform even in the case of a relatively flat design, so that the door or the like can be operated at any time without problems.
Die Unteransprüche stellen weitere Ausgestaltungen des erfindungsgemäßen Gegenstandes dar.The subclaims represent further refinements of the subject matter according to the invention.
Insbesondere, wenn nach einer bevorzugten Ausgestaltung eine Versteifungsschulter an der Stirnseite und je eine weitere Versteifungsschulter an den Querseiten vorgesehen ist, ergibt sich eine besonders verformungsarme Ausgestaltung des Gehäusedeckels.In particular, if, according to a preferred embodiment, a stiffening shoulder is provided on the front side and a further stiffening shoulder is provided on the transverse sides, this results in a particularly low-deformation design of the housing cover.
Der erfindungsgemäße Gegenstand wird anhand eines beispielhaft aufge- führten Ausführungsbeispieles näher erläutert.The subject matter of the invention is explained in more detail using an exemplary embodiment listed as an example.

In den Figuren ist von dem gesamten Bodentürschließer lediglich ein hier interessierender Gehäusedeckel 1 dargestellt. In Figur 3 ist eine Ansicht des erfindungsgemäßen Gehäusedeckels 1a von unten gezeigt. Der gleiche Gehäusedeckel 1a ist in Figur 5 in einer Ansicht von oben und in Figur 4 in einer Ansicht aus Richtung des Pfeiles X in Figur 3 dargestellt.Of the entire floor door closer, only one housing cover 1 of interest here is shown in the figures. FIG. 3 shows a view of the housing cover 1a according to the invention from below. The same housing cover 1a is shown in FIG. 5 in a view from above and in FIG. 4 in a view from the direction of arrow X in FIG.
Der Gehäusedeckel 1a ist in herkömmlicher Weise mit Schraubenlöchern a' bis e1 versehen, in welche Schrauben zur Verbindung des Gehäusedek- keis 1a mit einem nicht dargestellten Gehäuse eines Bodentürschließers eingesetzt werden können.The housing cover 1a is provided in a conventional manner with screw holes a 'to e 1 , in which screws can be used to connect the housing cover 1a with a housing of a floor closer, not shown.
Wie man aus den Figuren erkennt, sind von der Unterseite des Gehäuse- deckeis 1 a vorstehende Versteifungsschultern 2, 3 vorgesehen.As can be seen from the figures, stiffening shoulders 2, 3 projecting from the underside of the housing cover plate 1 a are provided.
Eine der Versteifungsschultern 2, 3, nämlich die Versteifungsschulter 2, ist bündig mit einer Stirnseite des Gehäusedeckels 1a ausgebildet und verläuft mittig zu einer Längsmittelachse L des Gehäusedeckels 1a. Sie hat einen geradlinigen Verlauf und erstreckt sich im Wesentlichen rechtwinke- lig zur Längsmittelachse L.One of the stiffening shoulders 2, 3, namely the stiffening shoulder 2, is formed flush with an end face of the housing cover 1a and extends centrally to a longitudinal central axis L of the housing cover 1a. It has a straight course and extends essentially at right angles to the longitudinal central axis L.
Die beiden anderen Versteifungsschultern 3 sind jeweils an den Querseiten des Gehäusedeckels 1a vorgesehen. Sie werden von einer Quermittelachse Q des Gehäusedeckels 1a durchschnitten und verlaufen nicht geradlinig wie die Versteifungsschulter 2, sondern sind mit einem Knick ver- sehen.The two other stiffening shoulders 3 are each provided on the transverse sides of the housing cover 1a. They are intersected by a transverse central axis Q of the housing cover 1a and do not run in a straight line like the stiffening shoulder 2, but are provided with a kink.
Anstelle des dargestellten Knicks können die Versteifungsschultern 3 auch z. B. gekrümmt ausgebildet sein.Instead of the kink shown, the stiffening shoulders 3 can also, for. B. be curved.
Die an den Querseiten des Gehäusedeckels 1a vorgesehenen Versteifungsschultern 3 sind an Vorsprüngen 4 ausgebildet, welche sich in der Ebene des Gehäusedeckels 1a in Richtung der Quermittelachse Q nach außen erstrecken. Die Versteifungsschultern 3 verlaufen auch hier bündig mit der Außenkante der Vorsprünge. Es versteht sich, dass die Versteifungsschultern an beliebigen Stellen des Gehäusedeckels 1a angeordnet sein können. Dabei kann die Anordnung symmetrisch oder asymmetrisch zu den Achsen Q und/oder L ausgeführt werden. Ebenfalls ist die Form nicht an eine bestimmte Gestaltung gebun- den. The stiffening shoulders 3 provided on the transverse sides of the housing cover 1a are formed on projections 4 which extend outward in the plane of the housing cover 1a in the direction of the transverse central axis Q. The stiffening shoulders 3 here also run flush with the outer edge of the projections. It is understood that the stiffening shoulders can be arranged anywhere on the housing cover 1a. The arrangement can be carried out symmetrically or asymmetrically to the axes Q and / or L. The shape is also not tied to a specific design.
