Definitions
- the present invention relates to a door closer with a door closer housing, which has a housing opening which is closed by a lid.
- Door closers are known, for example in the form of overhead door closers or floor door closers and serve to automatically close the wing of a door after its opening and subsequent release.
- a closer element such as a closer shaft is movably mounted, which can be coupled to the wing or an associated frame of the door.
- a closer drive can be accommodated as a closing spring, which provides the closing force.
- the components to be accommodated in the interior of the door closer housing can be introduced via the housing opening.
- the interior of a door closer housing is also filled with a damping fluid, which can also be done via the housing opening.
- the housing opening is closed with the lid.
- the lid must be tight and possibly fluid-tight.
- the covers of door closer housings may therefore be bolted or pinned to the cover seat. However, this is associated with a relatively high manufacturing and assembly costs.
- the cover has an elastically deformable and / or resilient holding section, by means of which the cover is clipped into a cover seat of the door closer housing and / or clamped or can be clipped and / or clamped.
- the lid can then be placed in the context of the production of the door closer in a simple manner to the housing opening and clipped with appropriate force and / or clamped. A complicated screwing is not required. There are also no additional fasteners such as screws, pins, bolts or retaining rings necessary, whereby the manufacturing costs can be reduced. Due to the resilient action of the elastically deformable holding portion of the lid is securely held in the lid seat after insertion into the housing opening.
- the elastically deformable holding portion can be designed relatively simple and is therefore easy to manufacture. It may be, for example, a strip, a tongue, a flange or a ring of an elastic material such as steel.
- the lid can also be made entirely of an elastic material.
- the production of a door closer can be considerably simplified by a cover which can be clipped into the cover seat of the door closer housing and / or clamped.
- the lid is held exclusively by a clip and / or clamp connection in the lid seat. That is, it is preferred that no additional screw, pin or locking ring connections are provided for holding the lid in the lid seat. As a result, the production costs can be kept particularly low.
- the cover may have a flat, the housing opening covering cover portion along the edge of the holding portion extends in particular in the circumferential direction.
- the circumferentially arranged holding section ensures reliable securing of the cover section in the housing opening.
- the holding portion may be formed flat.
- the cover can be designed as a sheet-metal component. Deep-drawn sheet metal components may have a bottom, a frame and a flange. In a deep-drawn lid thus the bottom can form the cover portion, while the frame and the flange together form the holding portion.
- the holding section can be formed completely circumferentially with respect to the cover section in the circumferential direction.
- the holding portion may comprise a flange portion extending radially outward from the cover portion.
- the flange portion Upon insertion of the lid in the lid seat, the flange portion is moved radially inwardly under elastic deformation of the lid, whereby a clamping action results.
- the flange portion In the presence of a corresponding recess in the cover seat, the flange portion can move radially outward again after reaching the end position and thus bring about a latching or a clipping.
- the flange portion may be inclined with respect to an areal extent of the deck portion. This means that a surface extension of the flange portion does not extend at an angle of 0 ° and not at an angle of 90 ° to the surface extension of the cover portion, but obliquely to this, for example at an angle of between 10 ° and 80 °, in particular between 30 ° and 60 °, in particular about 45 °. In an outward pressure on the lid, in particular by a hydraulic fluid in the door closer housing for damping a closing operation, this spreads due to the inclined flange portion in the lid seat, whereby the holding force is even increased.
- a special embodiment of the invention provides that the flange portion comprises circumferentially distributed locking lugs, which are separated by respective interruptions or recesses. Such locking lugs allow a particularly simple clipping or locking the lid in the lid seat.
- the holding portion has a peripheral to the edge of the cover portion skirt portion from which the flange portion projects radially outward.
- a jacket section may extend at least substantially at right angles to the planar extension of the cover section.
- the jacket portion may be formed by the frame. The shell portion may rest against an inner wall portion of the door closer housing, preferably by clamping, and thus increase the holding and sealing action.
- At least one receptacle for engagement of the holding portion of the lid may be formed on the lid seat.
- the holding section can clasp or snap into such a receptacle.
- a receptacle serve as an end stop when inserting the lid into the cover seat and thus contribute to the simplification of the assembly.
- such an end stop facilitates the correct positioning of the lid.
- a groove and / or a shoulder may be provided in a housing wall section surrounding the housing opening of the door closer housing. Such a groove or such a shoulder may in particular be formed completely encircling.
- a further embodiment of the invention provides that the cover has an excess, at least in sections, relative to the cover seat. As a result, there is a press fit, which improves the grip of the lid. In addition, the sealing effect is increased.
- a sealing element to be clamped between the cover and the door closer housing may be provided.
- the sealing element can be arranged on the cover or on the cover seat before final assembly of the door closer housing. If required, a plurality of sealing elements can be provided.
- the clip-in and / or clampable lid supports the use of clampable sealing elements.
- the sealing element may be arranged in a groove provided for the holding section of the lid or in a groove provided for the sealing element in the door closer housing. In such a groove, the sealing element is reliably held before merging the door closer housing and lid. In addition, the groove ensures always correct positioning of the sealing element.
- the sealing element can also be arranged in a groove formed on the cover, in particular the holding section.
- the sealing element can interact in particular in the region of the holding section with the lid.
- the elastic holding portion then exerts a pressure on the sealing element and thus contributes to an increase in the sealing effect.
- the lid may have a cup-like shape. This allows a particularly simple construction.
- the lid is formed as a deep-drawn part.
- deep-drawing enables particularly simple, rapid and cost-effective production.
- the holding section can be easily produced by deep drawing, for example as a frame and / or flange.
- the lid and the lid seat can be made of different materials. This can in particular increase the sealing effect.
- the materials are preferably selected specifically with regard to a sealing effect to be achieved.
- the door closer housing may have an elongated shape, wherein the opening is located on an end face of the door closer housing.
- the lid may then extend across a longitudinal axis of the door closer housing. It can also be provided on both end faces of an elongated door closer housing closable housing openings.
- the door closer housing may be formed as a fluid-filled hydraulic cylinder, in which a displaceable piston of the closer drive is guided.
- the lid can be designed in this case as a cylinder cover.
- the cover in a plan view may be round, in particular circular.
- the invention further relates to a system and / or arrangement comprising a door closer housing and a lid, wherein the door closer housing has a housing opening which is closed by the lid, and wherein the lid has an elastically deformable holding portion, by means of which the lid in a lid seat of Door closer housing is clipped and / or clamped. Described further developments relate both to the door closer according to the invention and to the system / arrangement according to the invention.
- door closer 11 may be formed as a top door closer or as a floor door closer and includes an elongated door closer housing 13 in which a not shown, coupled to a door of a swing door closer shaft is rotatably mounted.
- the door closer housing 13 forms a filled with a damping medium hydraulic cylinder, in the interior 15 a against the biasing force of a closer spring displaceable piston 17 is guided.
- a not shown, fixed to the closer shaft pinion engages in a rack of the piston 17 and ensures that upon rotation of the closer shaft, a displacement of the piston 17 and vice versa.
- the door closer housing 13 has an in Fig. 1 upper end face on a housing opening 19 which is circular here according to the cross section of the interior 15.
- the housing opening 19 is closed by a cover 21, which is held in a cover seat 25 of the door closer housing 13.
- the in Fig. 1 shown in a vertical orientation door closer 11 mounted horizontally.
- the lid 21 is designed as a deep-drawn part of an elastic material, preferably made of sheet steel, and accordingly has a cup-like shape. Specifically, a bottom of the cup-like lid 21 forms a flat, preferably flat cover section 27, which covers the housing opening 19. As in particular from the individual representations of the lid 21 according to Fig. 5 and 6 shows, around the edge 28 of the cover portion 27 encircling shell portion 29 extending transversely to the cover portion 27, here cylindrical side wall. Starting from the upper edge 30 of the jacket section 29 in the picture, a flange section 31 protrudes radially outward, which at the in Fig. 1 embodiment shown by a plurality of circumferentially distributed locking lugs 33 is formed. The latching lugs 33 are separated from one another by respective recesses 35 extending to the jacket section 29. As illustrated, the detents 33 are each inclined with respect to an areal extent of the deck portion 27.
- a first, inner groove 39 and a second outer groove 40 parallel thereto is formed in a housing wall opening 19 surrounding the inner wall portion 37 of the door closer housing 13. Both grooves 39, 40 are circumferentially completely formed circumferentially.
- a sealing element 45 in the form of an O-ring made of an elastic material.
- the sealing element 45 is further clamped between the shell portion 29 of the lid 21 and the inner wall portion 37.
- the jacket section 29 thus forms, together with the latching lugs 33, a holding section 47 which extends in the circumferential direction along the edge 28 of the cover section 27.
- the holding portion 47 is elastically deformable. It is thus possible to insert the lid 21 along a mounting direction M in the housing opening 19, wherein the locking lugs 33 are bent radially inwardly. Once the locking lugs 33 the outer groove 40 have reached, they snap into this and hold the lid 21 in the lid seat 25 firmly. At the same time, the jacket section 29 presses against the sealing element 45 located in the inner groove 39, so that a fluid-tight fit of the cover 21 is ensured. As a result, the cover 21 is clipped into the cover seat 25 and held in the cover seat 25 in a fluid-tight manner exclusively by the clip connection.
- Fig. 2 shows a second embodiment of the invention, which is designed similar to that in Fig. 1 shown embodiment, which is why like-acting components are denoted by the same reference numerals.
- the holding portion 47 'of in Fig. 7 and 8th has no latching noses. Rather, the flange portion 31 'of the holding portion 47' in the circumferential direction completely around the upper edge 30 of the shell portion 29 circumferentially formed.
- groove 50 is formed in the inner wall portion 37 'in the region of the cover seat 25' only a single, here opposite to the in Fig. 1 shown outer groove 40 widened.
- groove 50 is formed in a lower portion of this widened groove 50.
- a sealing element 45 is arranged, which, moreover, as in connection with Fig. 1 described sealing element is executed. The sealing element 45 thus directly adjoins the flange portion 31 '.
- the flange portion 31 'of the holding portion 47' is also formed completely circumferentially in the circumferential direction.
- a single groove 50 is formed, which is not widened here.
- the lid 21 ' is in principle designed as in Fig. 2 .
- Fig. 7 and Fig. 8 shown lid 21 ', except that it has a shortened skirt portion 29.
- the cover 21 ' also has an excess of the groove bottom 51 of the groove 50, so that the cover 21' is held with a press fit in the door closer housing 13. The press fit ensures a sufficient sealing effect, so that it is possible to dispense with a separate sealing element.
- the sealing effect is also reinforced by the fact that the lid 21 'and the inner wall portion 37' made of different, with respect to the sealing effect selected materials are.
- the flange portion 31' spreads into the groove 50, so that the holding and sealing action is further enhanced.
- the cover 21 ' is thus held in the cover seat 25' of the door closer housing 13 both by a clip connection and by a clamping connection.
- Fig. 4 shows a fourth embodiment of the invention, in which instead of one or two grooves, a slanting step 55 is formed in the inner wall section 37 ", the cover 21" does not have a jacket section in this embodiment.
- the flange portion 31 ' which is in turn formed completely circumferentially in the circumferential direction, directly from the edge 28 of the cover portion 27 from.
- the cover 21 has over the inner wall portion 37" of the door closer housing 13 on an excess, so that the lid 21 "as in the embodiment according to Fig. 3 is held with a press fit in the door closer housing 13.
- the press fit not only provides such a pronounced sealing effect that it is possible to dispense with a separate sealing element, but holds the lid 21 "without latching, ie the flange section 31 'forms an elastically deformable holding section 47".
- the sealing effect is reinforced by the fact that the cover 21 "and the inner wall section 37" are made of different materials which are specially selected with regard to the sealing effect.
- a clip-in and / or clampable lid has the advantage over lids to be screwed or pinned on, that not only the assembly is simplified, but that in addition to separate attachment means can be completely dispensed with.

Abstract
Ein Türschließer umfasst ein Türschließergehäuse, welches eine Gehäuseöffnung aufweist, die durch einen Deckel verschlossen ist. Der Deckel weist einen elastisch deformierbaren Halteabschnitt auf, mittels dem der Deckel in einen Deckelsitz des Türschließergehäuses eingeclipst und/oder eingeklemmt ist.A door closer comprises a door closer housing which has a housing opening which is closed by a cover. The lid has an elastically deformable holding section, by means of which the lid is clipped into a cover seat of the door closer housing and / or clamped.
Description
Die vorliegende Erfindung betrifft einen Türschließer mit einem Türschließergehäuse, welches eine Gehäuseöffnung aufweist, die durch einen Deckel verschlossen ist.The present invention relates to a door closer with a door closer housing, which has a housing opening which is closed by a lid.
Türschließer sind beispielsweise in Form von Obentürschließern oder Bodentürschließern bekannt und dienen dazu, den Flügel einer Tür nach dessen Öffnen und anschließendem Loslassen selbsttätig wieder zu schließen. Zu diesem Zweck ist in dem Türschließergehäuse üblicherweise ein Schließerelement wie eine Schließerwelle beweglich gelagert, welches mit dem Flügel oder einem zugehörigen Blendrahmen der Tür koppelbar ist. Weiterhin kann in dem Türschließergehäuse ein Schließerantrieb wie eine Schließerfeder untergebracht sein, welcher die Schließkraft bereitstellt.Door closers are known, for example in the form of overhead door closers or floor door closers and serve to automatically close the wing of a door after its opening and subsequent release. For this purpose, in the door closer housing usually a closer element such as a closer shaft is movably mounted, which can be coupled to the wing or an associated frame of the door. Furthermore, in the door closer housing, a closer drive can be accommodated as a closing spring, which provides the closing force.
Bei der Herstellung eines Türschließers können die im Inneren des Türschließergehäuses unterzubringenden Komponenten über die Gehäuseöffnung eingeführt werden. Häufig ist das Innere eines Türschließergehäuses außerdem mit einem Dämpfungsfluid zu befüllen, was ebenfalls über die Gehäuseöffnung erfolgen kann. Schließlich wird die Gehäuseöffnung mit dem Deckel verschlossen. Der Deckel muss fest und gegebenenfalls fluiddicht sitzen. Die Deckel von Türschließergehäusen können daher mit dem Deckelsitz verschraubt oder verstiftet sein. Dies ist jedoch mit einem relativ hohen Herstellungs- und Montageaufwand verbunden.In the manufacture of a door closer, the components to be accommodated in the interior of the door closer housing can be introduced via the housing opening. Frequently, the interior of a door closer housing is also filled with a damping fluid, which can also be done via the housing opening. Finally, the housing opening is closed with the lid. The lid must be tight and possibly fluid-tight. The covers of door closer housings may therefore be bolted or pinned to the cover seat. However, this is associated with a relatively high manufacturing and assembly costs.
Es ist eine Aufgabe der Erfindung, einen einfach und kostengünstig zu fertigenden Türschließer mit einem zuverlässig verschlossenen Gehäuse anzugeben.It is an object of the invention to provide a simple and inexpensive to produce door closer with a reliably sealed housing.
Die Lösung der Aufgabe erfolgt durch einen Türschließer mit den Merkmalen des Anspruchs 1.The object is achieved by a door closer with the features of claim 1.
Erfindungsgemäß weist der Deckel einen elastisch deformierbaren und/oder federnden Halteabschnitt auf, mittels dem der Deckel in einen Deckelsitz des Türschließergehäuses eingeclipst und/oder eingeklemmt ist bzw. einclipsbar und/oder einklemmbar ist. Der Deckel kann dann im Rahmen der Herstellung des Türschließers in einfacher Weise auf die Gehäuseöffnung aufgesetzt und unter entsprechender Kraftausübung eingeklipst und/oder eingeklemmt werden. Ein umständliches Einschrauben ist nicht erforderlich. Es sind auch keine zusätzlichen Befestigungselemente wie Schrauben, Stifte, Bolzen oder Sicherungsringe notwendig, wodurch die Fertigungskosten gesenkt werden können. Aufgrund der federnden Wirkung des elastisch deformierbaren Halteabschnitts wird der Deckel nach dem Einsetzen in die Gehäuseöffnung sicher im Deckelsitz gehalten. Ein besonderer Vorteil besteht hierbei darin, dass der elastisch deformierbare Halteabschnitt relativ einfach gestaltet sein kann und dementsprechend leicht zu fertigen ist. Es kann sich beispielsweise um einen Streifen, eine Zunge, einen Flansch oder einen Ring aus einem elastischen Material wie Stahlblech handeln. Der Deckel kann auch vollständig aus einem elastischen Material gefertigt sein. Die Fertigung eines Türschließers kann durch einen in den Deckelsitz des Türschließergehäuses einclipsbaren und/oder einklemmbaren Deckel beträchtlich vereinfacht werden.According to the invention, the cover has an elastically deformable and / or resilient holding section, by means of which the cover is clipped into a cover seat of the door closer housing and / or clamped or can be clipped and / or clamped. The lid can then be placed in the context of the production of the door closer in a simple manner to the housing opening and clipped with appropriate force and / or clamped. A complicated screwing is not required. There are also no additional fasteners such as screws, pins, bolts or retaining rings necessary, whereby the manufacturing costs can be reduced. Due to the resilient action of the elastically deformable holding portion of the lid is securely held in the lid seat after insertion into the housing opening. A particular advantage here is that the elastically deformable holding portion can be designed relatively simple and is therefore easy to manufacture. It may be, for example, a strip, a tongue, a flange or a ring of an elastic material such as steel. The lid can also be made entirely of an elastic material. The production of a door closer can be considerably simplified by a cover which can be clipped into the cover seat of the door closer housing and / or clamped.
Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen, der Beschreibung sowie den beigefügten Zeichnungen angegeben.Further developments of the invention are specified in the dependent claims, the description and the accompanying drawings.
Prinzipiell ist es bei Bedarf möglich, zusätzlich zu der Clips- und/oder Klemmverbindung eine weitere Verbindung wie zum Beispiel eine Schraubverbindung vorzusehen. Vorzugsweise ist der Deckel jedoch ausschließlich durch eine Clips- und/oder Klemmverbindung in dem Deckelsitz gehalten. Das heißt es ist bevorzugt, dass keine zusätzlichen Schraub-, Stift- oder Sicherungsring-Verbindungen zum Halten des Deckels im Deckelsitz vorgesehen sind. Dadurch können die Herstellungskosten besonders gering gehalten werden.In principle, it is possible, if necessary, in addition to the clip and / or clamp connection to provide a further connection, such as a screw connection. Preferably, however, the lid is held exclusively by a clip and / or clamp connection in the lid seat. That is, it is preferred that no additional screw, pin or locking ring connections are provided for holding the lid in the lid seat. As a result, the production costs can be kept particularly low.
Der Deckel kann einen flächigen, die Gehäuseöffnung abdeckenden Deckabschnitt aufweisen, entlang dessen Rand sich der Halteabschnitt insbesondere in Umfangsrichtung erstreckt. Der umfangsseitig angeordnete Halteabschnitt sorgt für eine zuverlässige Sicherung des Deckabschnitts in der Gehäuseöffnung. Auch der Halteabschnitt kann flächig ausgebildet sein. Insbesondere kann der Deckel insgesamt als flächiges Blechbauteil ausgeführt sein. Tiefgezogene Blechbauteile können einen Boden, eine Zarge und einen Flansch aufweisen. Bei einem tiefgezogenen Deckel kann somit der Boden den Deckabschnitt bilden, während die Zarge und der Flansch gemeinsam den Halteabschnitt bilden.The cover may have a flat, the housing opening covering cover portion along the edge of the holding portion extends in particular in the circumferential direction. The circumferentially arranged holding section ensures reliable securing of the cover section in the housing opening. Also, the holding portion may be formed flat. In particular, the cover can be designed as a sheet-metal component. Deep-drawn sheet metal components may have a bottom, a frame and a flange. In a deep-drawn lid thus the bottom can form the cover portion, while the frame and the flange together form the holding portion.
Um eine optimale Halt- und gegebenenfalls Dichtwirkung zu erzielen, kann der Halteabschnitt bezüglich des Deckabschnitts in Umfangsrichtung vollständig umlaufend ausgebildet sein.In order to achieve an optimal holding and optionally sealing action, the holding section can be formed completely circumferentially with respect to the cover section in the circumferential direction.
Weiterhin kann der Halteabschnitt einen sich von dem Deckabschnitt radial auswärts erstreckenden Flanschabschnitt umfassen. Bei einem Einsetzen des Deckels in den Deckelsitz wird der Flanschabschnitt unter elastischer Verformung des Deckels radial einwärts bewegt, wodurch eine Klemmwirkung resultiert. Bei Vorhandensein einer entsprechenden Aussparung im Deckelsitz kann sich der Flanschabschnitt nach Erreichen der Endposition wieder radial auswärts bewegen und somit eine Verrastung bzw. ein Einclipsen herbeiführen.Furthermore, the holding portion may comprise a flange portion extending radially outward from the cover portion. Upon insertion of the lid in the lid seat, the flange portion is moved radially inwardly under elastic deformation of the lid, whereby a clamping action results. In the presence of a corresponding recess in the cover seat, the flange portion can move radially outward again after reaching the end position and thus bring about a latching or a clipping.
Der Flanschabschnitt kann in Bezug auf eine Flächenerstreckung des Deckabschnitts geneigt sein. Das bedeutet, dass eine Flächenerstreckung des Flanschabschnitts nicht in einem Winkel von 0° und nicht in einem Winkel von 90° zu der Flächenerstreckung des Deckabschnitts verläuft, sondern schräg zu dieser, beispielsweise in einem Winkel von zwischen 10° und 80°, insbesondere zwischen 30° und 60°, insbesondere etwa 45°. Bei einem nach außen gerichteten Druck auf den Deckel, insbesondere durch eine Hydraulik-Flüssigkeit in dem Türschließergehäuse zur Dämpfung eines Schließvorgangs, spreizt sich dieser aufgrund des geneigten Flanschabschnitts im Deckelsitz ein, wodurch die Haltekraft sogar noch erhöht wird.The flange portion may be inclined with respect to an areal extent of the deck portion. This means that a surface extension of the flange portion does not extend at an angle of 0 ° and not at an angle of 90 ° to the surface extension of the cover portion, but obliquely to this, for example at an angle of between 10 ° and 80 °, in particular between 30 ° and 60 °, in particular about 45 °. In an outward pressure on the lid, in particular by a hydraulic fluid in the door closer housing for damping a closing operation, this spreads due to the inclined flange portion in the lid seat, whereby the holding force is even increased.
Eine spezielle Ausgestaltung der Erfindung sieht vor, dass der Flanschabschnitt in Umfangsrichtung verteilt angeordnete Rastnasen umfasst, welche durch jeweilige Unterbrechungen oder Aussparungen voneinander getrennt sind. Derartige Rastnasen ermöglichen ein besonders einfaches Einclipsen oder Einrasten des Deckels in den Deckelsitz.A special embodiment of the invention provides that the flange portion comprises circumferentially distributed locking lugs, which are separated by respective interruptions or recesses. Such locking lugs allow a particularly simple clipping or locking the lid in the lid seat.
Gemäß einer weiteren Ausgestaltung der Erfindung weist der Halteabschnitt einen um den Rand des Deckabschnitts umlaufenden Mantelabschnitt auf, von dem der Flanschabschnitt radial nach außen absteht. Ein solcher Mantelabschnitt kann zumindest im Wesentlichen rechtwinklig zu der flächigen Erstreckung des Deckabschnitts verlaufen. Bei einem tiefgezogenen Deckel kann der Mantelabschnitt durch die Zarge gebildet sein. Der Mantelabschnitt kann an einem Innenwandabschnitt des Türschließergehäuses anliegen, vorzugsweise klemmend, und so die Halt- und Dichtwirkung erhöhen.According to a further embodiment of the invention, the holding portion has a peripheral to the edge of the cover portion skirt portion from which the flange portion projects radially outward. Such a jacket section may extend at least substantially at right angles to the planar extension of the cover section. In a deep-drawn lid, the jacket portion may be formed by the frame. The shell portion may rest against an inner wall portion of the door closer housing, preferably by clamping, and thus increase the holding and sealing action.
Ferner kann an dem Deckelsitz wenigstens eine Aufnahme für einen Eingriff des Halteabschnitts des Deckels ausgebildet sein. Der Halteabschnitt kann in eine solche Aufnahme einclipsen oder einrasten. Alternativ oder zusätzlich kann eine Aufnahme als Endanschlag beim Einsetzen des Deckels in den Deckelsitz dienen und so zur Vereinfachung der Montage beitragen. Insbesondere erleichtert ein solcher Endanschlag die korrekte Positionierung des Deckels. Als Aufnahme kann insbesondere eine Nut und/oder ein Absatz in einem die Gehäuseöffnung umgebenden Innenwandabschnitt des Türschließergehäuses vorgesehen sein. Eine solche Nut oder ein solcher Absatz kann insbesondere vollständig umlaufend ausgebildet sein.Further, at least one receptacle for engagement of the holding portion of the lid may be formed on the lid seat. The holding section can clasp or snap into such a receptacle. Alternatively or additionally, a receptacle serve as an end stop when inserting the lid into the cover seat and thus contribute to the simplification of the assembly. In particular, such an end stop facilitates the correct positioning of the lid. In particular, a groove and / or a shoulder may be provided in a housing wall section surrounding the housing opening of the door closer housing. Such a groove or such a shoulder may in particular be formed completely encircling.
Eine weitere Ausführungsform der Erfindung sieht vor, dass der Deckel zumindest abschnittsweise gegenüber dem Deckelsitz ein Übermaß aufweist. Dadurch besteht eine Presspassung, welche den Halt des Deckels verbessert. Außerdem ist die Dichtwirkung erhöht.A further embodiment of the invention provides that the cover has an excess, at least in sections, relative to the cover seat. As a result, there is a press fit, which improves the grip of the lid. In addition, the sealing effect is increased.
Alternativ oder zusätzlich kann ein zwischen dem Deckel und dem Türschließergehäuse einzuklemmendes Dichtelement, beispielsweise in Form eines O-Rings, vorgesehen sein. Das Dichtelement kann vor der Endmontage des Türschließergehäuses je nach Ausgestaltung an dem Deckel oder an dem Deckelsitz angeordnet sein. Bei Bedarf können mehrere Dichtelemente vorgesehen sein. Der einclipsbare und/oder einklemmbare Deckel unterstützt die Verwendung von einklemmbaren Dichtelementen.Alternatively or additionally, a sealing element to be clamped between the cover and the door closer housing, for example in the form of an O-ring, may be provided. Depending on the configuration, the sealing element can be arranged on the cover or on the cover seat before final assembly of the door closer housing. If required, a plurality of sealing elements can be provided. The clip-in and / or clampable lid supports the use of clampable sealing elements.
Das Dichtelement kann in einer für den Halteabschnitt des Deckels vorgesehenen Nut oder in einer eigens für das Dichtelement vorgesehenen Nut im Türschließergehäuse angeordnet sein. In einer solchen Nut ist das Dichtelement vor dem Zusammenführen von Türschließergehäuse und Deckel zuverlässig gehalten. Außerdem sorgt die Nut für eine stets korrekte Positionierung des Dichtelements. Alternativ oder zusätzlich kann das Dichtelement auch in einer an dem Deckel, insbesondere dem Halteabschnitt ausgebildeten Nut angeordnet sein.The sealing element may be arranged in a groove provided for the holding section of the lid or in a groove provided for the sealing element in the door closer housing. In such a groove, the sealing element is reliably held before merging the door closer housing and lid. In addition, the groove ensures always correct positioning of the sealing element. Alternatively or additionally, the sealing element can also be arranged in a groove formed on the cover, in particular the holding section.
Das Dichtelement kann insbesondere im Bereich des Halteabschnitts mit dem Deckel zusammenwirken. Der elastische Halteabschnitt übt dann einen Druck auf das Dichtelement aus und trägt somit zu einer Verstärkung der Dichtwirkung bei.The sealing element can interact in particular in the region of the holding section with the lid. The elastic holding portion then exerts a pressure on the sealing element and thus contributes to an increase in the sealing effect.
Der Deckel kann eine napfartige Form aufweisen. Dies ermöglicht eine besonders einfache Konstruktion.The lid may have a cup-like shape. This allows a particularly simple construction.
Vorzugsweise ist der Deckel als Tiefziehteil ausgebildet. Im Gegensatz zu einer spanenden Formgebung oder einem Gussverfahren ermöglicht das Tiefziehen eine besonders einfache, schnelle und kostengünstige Herstellung. Der Halteabschnitt ist leicht durch Tiefziehen herstellbar, zum Beispiel als Zarge und/oder Flansch.Preferably, the lid is formed as a deep-drawn part. In contrast to a metal-cutting or casting process, deep-drawing enables particularly simple, rapid and cost-effective production. The holding section can be easily produced by deep drawing, for example as a frame and / or flange.
Der Deckel und der Deckelsitz können aus unterschiedlichen Materialien gefertigt sein. Dies kann insbesondere die Dichtwirkung erhöhen. Bevorzugt sind die Materialien speziell im Hinblick auf eine zu erzielende Dichtwirkung ausgewählt.The lid and the lid seat can be made of different materials. This can in particular increase the sealing effect. The materials are preferably selected specifically with regard to a sealing effect to be achieved.
Das Türschließergehäuse kann eine längliche Form aufweisen, wobei sich die Öffnung an einer Stirnseite des Türschließergehäuses befindet. Der Deckel kann sich dann quer zu einer Längsachse des Türschließergehäuses erstrecken. Es können auch an beiden Stirnseiten eines länglichen Türschließergehäuses verschließbare Gehäuseöffnungen vorgesehen sein. Insbesondere kann das Türschließergehäuse als fluidgefüllter Hydraulikzylinder ausgebildet sein, in welchem ein verschiebbarer Kolben des Schließerantriebs geführt ist. Der Deckel kann in diesem Fall als Zylinderdeckel ausgeführt sein. Insbesondere kann der Deckel in einer Draufsicht rund, insbesondere kreisrund, sein.The door closer housing may have an elongated shape, wherein the opening is located on an end face of the door closer housing. The lid may then extend across a longitudinal axis of the door closer housing. It can also be provided on both end faces of an elongated door closer housing closable housing openings. In particular, the door closer housing may be formed as a fluid-filled hydraulic cylinder, in which a displaceable piston of the closer drive is guided. The lid can be designed in this case as a cylinder cover. In particular, the cover in a plan view may be round, in particular circular.
Die Erfindung betrifft weiterhin ein System und/oder eine Anordnung umfassend ein Türschließergehäuse und einen Deckel, wobei das Türschließergehäuse eine Gehäuseöffnung aufweist, die durch den Deckel verschlossen ist, und wobei der Deckel einen elastisch deformierbaren Halteabschnitt aufweist, mittels dem der Deckel in einen Deckelsitz des Türschließergehäuses eingeclipst und/oder eingeklemmt ist. Beschriebene Weiterbildungen betreffen sowohl den erfindungsgemäßen Türschließer als auch das/die erfindungsgemäße System/Anordnung.The invention further relates to a system and / or arrangement comprising a door closer housing and a lid, wherein the door closer housing has a housing opening which is closed by the lid, and wherein the lid has an elastically deformable holding portion, by means of which the lid in a lid seat of Door closer housing is clipped and / or clamped. Described further developments relate both to the door closer according to the invention and to the system / arrangement according to the invention.

Das Türschließergehäuse 13 weist an einer in
Der Deckel 21 ist als Tiefziehteil aus einem elastischen Material, vorzugsweise aus Stahlblech, ausgeführt und weist dementsprechend eine napfartige Form auf. Speziell bildet ein Boden des napfartigen Deckels 21 einen flächigen, vorzugsweise ebenen Deckabschnitt 27, welcher die Gehäuseöffnung 19 abdeckt. Wie insbesondere aus den Einzeldarstellungen des Deckels 21 gemäß
In einem die Gehäuseöffnung 19 umgebenden Innenwandabschnitt 37 des Türschließergehäuses 13 ist eine erste, innere Nut 39 und eine hierzu parallele zweite, äußere Nut 40 ausgebildet. Beide Nuten 39, 40 sind in Umfangsrichtung vollständig umlaufend ausgebildet. In der dem Innenraum 15 zugewandten inneren Nut 39 befindet sich ein Dichtelement 45 in Form eines O-Rings aus einem elastischen Material. In die dem Innenraum 15 abgewandte äußere Nut 40 greifen die Rastnasen 33 des Deckels 21 ein. Das Dichtelement 45 ist weiterhin zwischen dem Mantelabschnitt 29 des Deckels 21 und dem Innenwandabschnitt 37 eingeklemmt. Der Mantelabschnitt 29 bildet somit gemeinsam mit den Rastnasen 33 einen Halteabschnitt 47, der sich in Umfangsrichtung entlang des Rands 28 des Deckabschnitts 27 erstreckt.In a housing wall opening 19 surrounding the
Da der Deckel 21 aus einem elastischen bzw. federnden Material gefertigt ist, ist der Halteabschnitt 47 elastisch deformierbar. Es ist somit möglich, den Deckel 21 entlang einer Montagerichtung M in die Gehäuseöffnung 19 einzuführen, wobei die Rastnasen 33 radial einwärts gebogen werden. Sobald die Rastnasen 33 die äußere Nut 40 erreicht haben, schnappen sie in diese ein und halten den Deckel 21 in dem Deckelsitz 25 fest. Gleichzeitig drückt der Mantelabschnitt 29 gegen das in der inneren Nut 39 befindliche Dichtelement 45, sodass ein fluiddichter Sitz des Deckels 21 gewährleistet ist. Im Ergebnis ist der Deckel 21 in den Deckelsitz 25 eingeclipst und ausschließlich durch die Clipsverbindung fluiddicht in dem Deckelsitz 25 gehalten.Since the
Bei der in
Ein einclipsbarer und/oder einklemmbarer Deckel weist gegenüber zu verschraubenden oder zu verstiftenden Deckeln den Vorteil auf, dass nicht nur die Montage vereinfacht ist, sondern dass darüber hinaus auch auf separate Befestigungsmittel vollständig verzichtet werden kann. Zudem ermöglicht die Ausführung als Blechteil und insbesondere als Tiefziehteil eine besonders kostengünstige Fertigung.A clip-in and / or clampable lid has the advantage over lids to be screwed or pinned on, that not only the assembly is simplified, but that in addition to separate attachment means can be completely dispensed with. In addition, the design allows as a sheet metal part and in particular as a deep-drawn part a particularly cost-effective production.
