Description

KältegerätRefrigerator
Die Erfindung betrifft ein Kältegerät, wie ein Kühl- oder Gefriergerät oder dergleichen, mit einem wärmeisolierenden Gehäuse und wenigstens einer Tür, über welcher am Gehäuse eine zur Aufnahme einer elektronischen Steuerung oder Anzeigeelementen oder dergleichen dienende haubenähnliche Abdeckung vorgesehen ist, welche an ihrer Frontseite wenigstens eine zu dieser hin offene und durch eine Blende zumindest weitestgehend abgedeckte Aufnahme aufweist, über welche eine von einem Kraftspeicher beaufschlagte und entgegen der Wirkung des Kraftspeichers in der Aufnahme gehaltene Drucktaste aus der Abdeckung herausgeführt ist.The invention relates to a refrigerator, such as a refrigerator or freezer or the like, with a heat-insulating housing and at least one door, above which a hood-like cover is provided on the housing for receiving an electronic control or display elements or the like, which cover has at least one on its front side to this open and at least largely covered receptacle via which a pushbutton acted upon by an energy accumulator and held against the effect of the energy accumulator in the receptacle is led out of the cover.
Bei Kühl- und Gefriergeräten ist es Stand der Technik, daß über deren Türen als so- genannte Vorsatzgehäuse bezeichnete haubenähnliche Abdeckungen zur Unterbringung von Anzeigeelementen oder aber auch mit elektronischen Bauteilen bestückte Leiterplatten angeordnet sind, auf denen dann üblicherweise ein als Geräteschalter dienender Druckschalter festgesetzt ist, welcher über eine aus der Abdeckung herausgeführte und für eine Bedienperson zugängliche Drucktaste betätigbar ist. Die Druck- taste ist dabei in einer an der Abdeckung vorgesehenen Aufnahme gelagert und durch eine Feder in eine definierte Bedienposition gedrückt, wobei die von der Feder auf die Drucktaste ausgeübte Kraft von einer an der Frontseite der Abdeckung vorgesehenen und die Aufnahme abdeckende Verblendung abgefangen ist, durch welche die Drucktaste über einen Durchbruch hindurchgeführt ist. Um die auf die Drucktaste mittels ei- ner Feder ausgeübte Kraft durch die Blende abfangen zu können, ist letztere entweder durch ihre Gestaltung oder durch die Werkstoffwahl entsprechend formsteif auszubilden. Die nötige Biegesteifheit der Blende wurde bei den bekannten Ausführungsformen entweder durch ein metallisches Verkleidungsprofil oder durch ein Kunststoffprofil mit entsprechender Materialstärke erreicht. Für den Fall, daß die Verkleidungs- profile zudem mit Markierungen zur Darstellung der Einstell- und Geräteparameter versehen werden sollen, ist das Bedrucken derartiger Verblendungsprofile mit den entsprechenden Markierungen ziemlich kostenträchtig, da jedes der Verblendungsprofile im Einzelverfahren bedruckt werden muß. Darüber hinaus gestaltet sich eine Beleuch- tung der Markierungen, um diese für eine Bedienperson besser kenntlich zu machen, insbesondere bei aus metallischen Werkstoffen hergestellten Verblendungsprofilen äußerst aufwendig. Bei Kunststoffverblendungen gestaltet sich die Beleuchtung der Markierungen durch die Wahl eines durchscheinenden Werkstoffes zwar einfacher, jedoch ist die aus Steifigkeitsgründen mit relativ hoher Materialstärke zu dimensionie- rende Kunststoffverblendung nur relativ schwierig mit einem gefälligen Design in die Abdeckung zu integrieren.In the case of refrigerators and freezers, it is state of the art that hood-like covers, known as so-called front housings, for accommodating display elements or else printed circuit boards equipped with electronic components are arranged on their doors, on which a pressure switch serving as a device switch is then usually fixed, which can be actuated via a push button which is led out of the cover and is accessible to an operator. The pushbutton is mounted in a receptacle provided on the cover and pressed into a defined operating position by a spring, the force exerted by the spring on the pushbutton being intercepted by a facing provided on the front of the cover and covering the receptacle, through which the push button is passed over an opening. In order to be able to absorb the force exerted on the pushbutton by means of a spring through the cover, the latter must be designed to be dimensionally stable either by its design or by the choice of material. The necessary bending stiffness of the panel was achieved in the known embodiments either by a metal cladding profile or by a plastic profile with the appropriate material thickness. In the event that the cladding Profiles should also be provided with markings to represent the setting and device parameters, the printing of such veneer profiles with the corresponding markings is quite costly, since each of the veneer profiles must be printed in a single process. In addition, the markings are illuminated in order to make them easier to recognize for an operator, particularly in the case of veneer profiles made of metallic materials, which is extremely complex. In the case of plastic facings, the lighting of the markings is made easier by the choice of a translucent material, but it is relatively difficult to integrate the plastic facings with a pleasing design into the cover for reasons of rigidity with a relatively high material thickness.
Der Erfindung liegt die Aufgabe zugrunde, bei einem Kältegerät gemäß dem Oberbegriff des Anspruches 1 mit einfachen konstruktiven Maßnahmen die Nachteile des Standes der Technik zu vermeiden und darüber hinaus die Montage zu verbessern.The invention has for its object to avoid the disadvantages of the prior art in a refrigerator according to the preamble of claim 1 with simple design measures and also to improve the assembly.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Drucktaste und/oder die Abdeckung Mittel aufweisen, welche beim Einfügen der Drucktaste in die Aufnahme zusammenwirken und die Drucktaste und die Abdeckung entgegen der Wirkung des Kraftspeichers zusammenzuhalten vermögen.This object is achieved according to the invention in that the push button and / or the cover have means which cooperate when the push button is inserted into the receptacle and are able to hold the push button and the cover together against the action of the energy accumulator.
Durch die erfindungsgemäße Maßnahme erfolgt die Abstützung der über den Kraftspeicher auf die Drucktaste zu deren genauer Positionsdefinition eingeleiteten Kraft ausschließlich auf die statisch von vornherein ausreichend dimensionierten Bauteile, nämlich die Drucktaste einerseits und die Abdeckung andererseits, so daß von einer das Abdeckgehäuse frontseitig verkleidenden Verblendung keinerlei Kräfte aufzunehmen sind, wodurch sich für diese Verblendung die Möglichkeit ergibt, diese beispielsweise aus kostengünstig zu bedruckendem Folienmaterial herzustellen. Darüber hinaus ist die Drucktaste nach ihrem Einfügevorgang in die Aufnahme der Abdeckung ohne zusätzliche Maßnahmen bereits an dieser fixiert. Des weiteren ergibt sich der Vorteil, daß die Abdeckung und die Drucktaste als vormontierte Baueinheit bereitgestellt und von einer Zulieferfirma bezogen werden kann, da das Verblendungsprofil mit den darauf aufgebrachten gerätespezifischen Einstellmarkierungen nicht mehr notwendigerweise Bestandteil der vormontierten Baugruppe sein muß, sondern vom Käl- tegerätehersteller gerätespezifisch in einem fortgeschrittenen Stadium des Fertigungsverfahrens am Kältegerät angebracht werden kann. Entsprechend einer bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Mittel als Rasthaken ausgebildet sind, welche mit Vorsprüngen an der Drucktaste und/oder der Abdeckung formschlüssig zusammenzuwirken vermö- gen.The measure according to the invention supports the force introduced via the energy accumulator onto the pushbutton for the precise definition of its position exclusively on the statically sufficiently dimensioned components, namely the pushbutton on the one hand and the cover on the other hand, so that no forces are exerted by a covering covering the front of the cover housing are to be recorded, which results in the possibility of this veneer being produced, for example, from film material which can be printed inexpensively. In addition, the pushbutton is already fixed to the cover after its insertion into the receptacle without additional measures. Furthermore, there is the advantage that the cover and the push button can be provided as a pre-assembled unit and can be obtained from a supplier, since the facing profile with the device-specific setting markings applied thereon no longer necessarily have to be a component of the pre-assembled module, but rather device-specific from the refrigeration device manufacturer can be attached to the refrigerator at an advanced stage of the manufacturing process. According to a preferred embodiment of the subject matter of the invention, it is provided that the means are designed as latching hooks which are able to cooperate with projections on the push button and / or the cover in a form-fitting manner.
Hierdurch ist ein einfaches und sicheres Zusammenfügen und Verrasten der Drucktaste mit der Abdeckung von der offenen Seite der Aufnahme her möglich, wodurch großflächige und zugleich mit vorsichtiger Handhabung zu montierende Bauteile, wie beispielsweise die elektronische Steuerung, vor dem Einbringen der Drucktaste in der haubenähnlichen Abdeckung montiert sein können.This enables simple and secure assembly and locking of the pushbutton with the cover from the open side of the receptacle, as a result of which large components that are to be assembled with careful handling, such as the electronic control, are mounted in the hood-like cover before the pushbutton is inserted could be.
Gemäß einer nächsten bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß wenigstens zwei Rasthaken vorgesehen sind, die zumindest annähernd einander gegenüberliegend angeordnet sind.According to a next preferred embodiment of the object of the invention, it is provided that at least two locking hooks are provided, which are arranged at least approximately opposite one another.
Durch eine derartige Maßnahme ist nicht nur eine Schiefstellung der mit dem Kraftspeicher beaufschlagten Drucktaste vermieden, sondern zugleich auch erreicht, daß sich die Drucktaste in ihrer durch die Federkraft bestimmten Ausgangsposition nicht verkantet und somit bei der Betätigung der Drucktaste, deren Leichtgängigkeit garantiert ist.Such a measure not only prevents skewing of the pushbutton acted upon by the energy accumulator, but at the same time also ensures that the pushbutton does not jam in its starting position determined by the spring force and thus when the pushbutton is actuated, its smooth operation is guaranteed.
Konstruktiv und fertigungstechnisch besonders einfach gestaltet sich die Verbindung zwischen der Drucktaste und der Abdeckung, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß die Rasthaken an der Drucktaste angeordnet sind und mit je einem Vorsprung an der Abdeckung formschlüssig zusammenwirken.The connection between the pushbutton and the cover is particularly simple in terms of construction and manufacturing technology if, according to a next advantageous embodiment of the object of the invention, it is provided that the latching hooks are arranged on the pushbutton and interact positively with a projection on the cover.
Besonders einfach herzustellen sind die Vorsprünge, wenn nach einer weiteren bevor- zugten Ausführungform des Gegenstandes der Erfindung vorgesehen ist, daß die Vorsprünge an den Napfwänden der Aufnahme vorgesehen sindThe projections are particularly easy to manufacture if, according to a further preferred embodiment of the object of the invention, it is provided that the projections are provided on the cup walls of the receptacle
Besonders robust und leicht zugänglich sind die Vorsprünge an der haubenähnlichen Abdeckung, wenn nach einer nächsten bevorzugten Ausführungsform des Gegen- Standes der Erfindung vorgesehen ist, daß die Vorsprünge an den Wänden der Aufnahme außerhalb des von dieser umgrenzten Raumes angeordnet und über im Boden der Aufnahme vorgesehene Durchtrittsöffnungen zugänglich sind, welchen Zuführschrägen vorgelagert sind, entlang welcher die Rashaken den Durchtrittsöffnungen zugeführt sind.The projections on the hood-like cover are particularly robust and easily accessible if, according to a next preferred embodiment of the subject of the invention, it is provided that the projections are arranged on the walls of the receptacle outside of the space delimited by it and above in the floor through openings provided in the receptacle are accessible, upstream of which feed bevels along which the rash hooks are fed to the through openings.
Gemäß einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung ist vorgesehen, daß den Durchtrittsöffnungen Zuführschrägen vorgelagert sind, entlang welchen die Rasthaken den Durchtrittsöffnungen zugeführt sind.According to a next advantageous embodiment of the object of the invention, it is provided that the through openings are preceded by bevels along which the latching hooks are fed to the through openings.
Hierdurch ist ein zielsicheres, mit geringem Zeitaufwand verbundenes und somit ein großseriengerechtes Zusammenfügen und Verbinden der Drucktaste mit der Abdeckung gewährleistet.This ensures a reliable, time-saving and therefore large-scale assembly and connection of the push button with the cover.
Nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Aufnahme stufenartig in ihren Raum ragende Absätze auf- weist, welche als Tiefenanschläge für den Verschiebeweg des Drucktasters in der Aufnahme dienen.According to a further preferred embodiment of the object of the invention, it is provided that the receptacle has shoulders projecting into its space in steps, which serve as depth stops for the displacement path of the pushbutton in the receptacle.
Durch die Verschiebewegbegrenzung für den Drucktaster ist sichergestellt, daß der beispielsweise auf einer Leiterplatte montierte Druckschalter auch infolge einer über- mäßigen Krafteinleitung auf den Drucktaster keinen Schaden nimmt.The travel path limitation for the pushbutton ensures that the pressure switch, which is mounted on a printed circuit board, for example, is not damaged as a result of excessive force being applied to the pushbutton.
Besonders einfach herstellbar und zugleich in der Aufnahme der Abdeckung unterbringbar ist ein Kraftspeicher, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß die Drucktaste mit einer als Kraftspeicher dienenden Blattfeder versehen ist, welche sich an der Bodenwand der Aufnahme abstützt. Zudem ist durch die Zuordnung der Blattfeder zur Drucktaste der Montagevorgang der Drucktaste zu der Aufnahme deutlich vereinfacht.A force accumulator is particularly easy to produce and at the same time can be accommodated in the receptacle of the cover if, according to a next advantageous embodiment of the object of the invention, it is provided that the push button is provided with a leaf spring serving as an energy accumulator, which is supported on the bottom wall of the receptacle. In addition, the assembly process of the push button to the receptacle is significantly simplified by the assignment of the leaf spring to the push button.
Gemäß einer letzten bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Drucktaste aus Kunststoffspritzguß hergestellt ist, an welche die Blattfeder einstückig mitangeformt ist.According to a last preferred embodiment of the object of the invention it is provided that the push button is made of injection molded plastic, to which the leaf spring is integrally formed.
Durch eine derartige Ausführung der Drucktaste ist diese nicht nur besonders kostengünstig herstellbar, sondern zugleich infolge der Teilereduzierung besonders einfach montierbar. Die Erfindung ist in der nachfolgenden Beschreibung anhand eines in der beigefügten Zeichnung vereinfacht dargestellten Ausführungsbeispieles erläutert.Such a design of the push button not only makes it particularly cost-effective to manufacture, but at the same time it is particularly easy to assemble due to the reduction in parts. The invention is explained in the following description with reference to an embodiment shown in simplified form in the accompanying drawing.

In addition to electrical display elements (not shown), the cover 10 also accommodates a printed circuit board 12 which carries a pressure switch 13 and which is fixed within the receiving space of the cover 10 by means of latching means 14 provided on the legs 11. The U-shaped cover 10 is provided on the outside of its base serving as the front wall 15 serving as a visible surface with a receiving region 16 which springs back in steps in relation to the outside. Within the recording area
16 ist eine napfähnlich ausgebildete, zur Außenseite der Frontwand 15 hin offen ausgebildete und sich zu den freien Enden der Schenkel 11 hin erstreckende, napfähnlich geformte Aufnahme 17 mit rechteckförmigem Querschnitt vorgesehen. Die Aufnahme16 is a bowl-shaped receptacle 17 with a rectangular cross-section, designed to be open towards the outside of the front wall 15 and extending towards the free ends of the legs 11, and shaped like a bowl. The recording
17 weist einen Napfraum 18 auf, dessen Tiefe zu den freien Enden der Schenkel 11 hin durch einen Napfboden 19 begrenzt ist, welcher in seinem Zentrum einen Durchbruch 20 aufweist und welcher an seinen Randabschnitten mit Durchtrittsöffnungen 21 versehen ist. Der Napfboden 19 ist zur seitlichen Eingrenzung des Napfraumes 18 mit seitlichen Napfwänden 22 verbunden, von denen die im wesentlichen senkrecht zu den Schenkeln 11 verlaufenden Napfwände mit stufenartig in den Napfraum 18 ragenden, als Tiefenanschlag dienenden, einander gegenüberliegenden Absätzen 23 versehen sind, deren parallel zur Frontwand 15 verlaufende Stufenabschnitte als Anschlagfläche 24 dienen. Neben den stufenartig ausgeführten Absätzen 23 weisen die senkrecht zu den Schenkeln 11 angeordneten Napfwände 22 in den Durchtrittsöffnungen 21 mündende Zuführschrägen 25 auf, welche mit ihrer schiefen Ebene zu den Durchtrittsöff- nungen 21 hingerichtet sind und welche an diesen Napfwänden 22 nicht unmittelbar einander gegenüberliegend angeordnet sind, sondern einen seitlichen Versatz zueinander aufweisen. Die senkrecht zu den Schenkeln 11 ausgerichteten Napfwände 22 weisen im Bereich der Durchtrittsöffnungen 21 jeweils einen Vorsprung 26 auf, welcher mit seinem freien Ende zur Leiterplatte 12 hin gerichtet ist.17 has a bowl space 18, the depth of which is limited towards the free ends of the legs 11 by a bowl bottom 19 which has an opening 20 in its center and which is provided with passage openings 21 at its edge sections. The bowl bottom 19 is connected to the lateral delimitation of the bowl space 18 with lateral bowl walls 22, of which the bowl walls which run essentially perpendicular to the legs 11 are provided with step-like projections into the bowl space 18, serving as a depth stop, opposite shoulders 23, the parallel to which Front wall 15 extending step sections serve as stop surface 24. In addition to the step-like shoulders 23, the cup walls 22 arranged perpendicular to the legs 11 have feed bevels 25 which open into the through openings 21 and which have an inclined plane to the through openings. openings 21 are executed and which are not arranged directly opposite each other on these cup walls 22, but have a lateral offset to one another. The cup walls 22 aligned perpendicular to the legs 11 each have a projection 26 in the area of the passage openings 21, which has its free end directed towards the printed circuit board 12.
Der Napfraum 18 der Aufnahme 17 dient zur Einbringung eines Drucktasters 27, welcher ein im wesentlichen in Form eines Kreiszylinders ausgebildetes Bedienteil 28 aufweist, welches mit einer seiner Stirnseiten bezüglich der Frontwand 15 übersteht und an dieser Stirnseite mit einer zur Bedienung des Drucktasters 27 dienenden linsenförmig geformten Abdeckung 29 versehen ist. Gegenüber der Abdeckung 29 weist das Bedienteil 28 an seinem anderen freien Ende zwei einander gegenüberliegende, den mit den Absätzen 23 ausgestatteten Napfwänden 22 zugewandte Ausleger 30 auf. Diese sind im Nahbereich ihres freien Randes, an ihrer dem Napfboden 19 zugewand- ten Unterseite mit federnden Rasthaken 31 ausgestattet, welche im Einbauzustand des Drucktasters 27 in der Aufnahme 17 die in dessen Napfboden 19 vorgesehenen Durchtrittsöffnungen 21 durchdringen und mit ihrem parallel zum Napfboden 19 verlaufenden Hakenabschnitt die Vorsprünge 26 hintergreifen. Ferner ist an der Unterseite eines jeden Auslegers 30 eine Blattfeder 32 festgesetzt, welche sich mit ihrem freien Ende im Einbauzustand des Drucktasters 27 unter Vorspannung an der dem Bedienteil 28 zugewandten Innenseite des Napfbodens 19 abstützt (siehe hierzu Fig. 2). Das Bedienteil 28 ist ferner mit einer Betätigungshülse 33 ausgestattet, welche konzentrisch innerhalb des Bedienteiles 28 angeordnet ist und mit ihrem freien Ende gegenüber dem Bedienteil 28 vorspringt. Das vorspringende Ende der Betätigungshülse 33 durchdringt den Durchbruch 20 im Napfboden 19 und steht mit dem Druckstößel des Druckschalters 13 in Eingriff. Das Bedienteil 28 durchdringt eine in einer folienartigen, gegebenenfalls durchscheinend ausgebildeten und mit Geräteeinstellmarkierungen bedruckten Blende 34 eingebrachte Öffnung 35 und sitzt innerhalb des Aufnahmebereiches 16, wobei die Öffnung 35 zumindest weitestgehend auf den Durchmesser des Bedienteiles 28 abgestimmt ist. Das durch die Öffnung 35 hindurchtretende Bedienteil 28 steht mit der zu seiner Bedienung dienenden Abdeckung 29 gegenüber der die frontseitig offene Aufnahme 17 abdeckende Blende 34 über. Durch die vor der Montage der Blende 34 frontseitig offene Aufnahme 17 läßt sich die Drucktaste 27 auch noch nach der bereits erfolgten Montage der Leiterplatte 12 in die Aufnahme 17 einfü- gen. Das positionsrichtige Einsetzen der Drucktaste 27 in der Aufnahme 17 ist durch die Ausleger 30 der ersteren bestimmt, welche mit ihren freien, von der Betäti- gungshülse 33 abgewandten Enden entlang der Innenseiten der mit den Absätzen 23 ausgestatteten Napfwände 22 zu gleiten vermögen. Beim Einsetzvorgang der Drucktaste 27 in die Aufnahme 19 werden die Rasthaken 31 über die Zuführschrägen 25 den Durchtrittsöffnungen 21 zugeführt und durchdringen diese, bevor sie mit ihren parallel zu den Auslegern 30 verlaufenden Abschnitten an den Vorsprüngen 26 verra- sten. In dieser Rastposition üben die sich am Napfboden 19 unter Vorspannung abstützenden Blattfedern 32 eine Vorspannkraft auf die mittels ihrer Rasthaken 31 an der Abdeckung 10 verrasteten Drucktaste 27 aus. Der Betätigungshub der Drucktaste 27 ist durch das Zusammenwirken der Anschlagfläche 24 mit der ihr zugewandten Unter- seite an den Auslegern 30 begrenzt, wodurch die von einer Bedienperson über die Drucktaste 27 auf den Druckschalter 13 ausübbare Kraft limitiert ist und somit eine Beschädigung des Druckschalters 13 vermieden ist.The bowl space 18 of the receptacle 17 is used for introducing a pushbutton 27 which has an operating part 28 which is essentially in the form of a circular cylinder and which protrudes with one of its end faces with respect to the front wall 15 and on this end face with a lens-shaped part serving to operate the pushbutton 27 Cover 29 is provided. Compared to the cover 29, the operating part 28 has at its other free end two mutually opposite arms 30 facing the cup walls 22 equipped with the shoulders 23. These are equipped in the vicinity of their free edge, on their underside facing the bowl bottom 19, with resilient latching hooks 31 which, when the pushbutton 27 is in the installed state in the receptacle 17, penetrate the passage openings 21 provided in its bowl bottom 19 and which run parallel to the bowl bottom 19 Hook portion engage behind the projections 26. Furthermore, a leaf spring 32 is fixed on the underside of each arm 30, which is supported with its free end in the installed state of the pushbutton 27 under pretension on the inside of the bowl bottom 19 facing the operating part 28 (see FIG. 2). The control panel 28 is also equipped with an actuating sleeve 33, which is arranged concentrically within the control panel 28 and projects with its free end relative to the control panel 28. The projecting end of the actuating sleeve 33 penetrates the opening 20 in the cup base 19 and is in engagement with the pressure plunger of the pressure switch 13. The operating part 28 penetrates an opening 35 made in a film-like, possibly translucent and printed with device setting markings and sits within the receiving area 16, the opening 35 being at least largely matched to the diameter of the operating part 28. The operating part 28 passing through the opening 35 projects with the cover 29 serving for its operation in relation to the cover 34 covering the receptacle 17 which is open at the front. Due to the receptacle 17 which is open on the front prior to the assembly of the panel 34, the pushbutton 27 can also be inserted into the receptacle 17 after the circuit board 12 has already been assembled. The positionally correct insertion of the pushbutton 27 in the receptacle 17 is ensured by the extension arm 30 the former determines which, with their free, Gungshülse 33 opposite ends are able to slide along the inner sides of the cup walls 22 equipped with paragraphs 23. When the pushbutton 27 is inserted into the receptacle 19, the latching hooks 31 are fed to the through-openings 21 via the feed bevels 25 and penetrate them before they engage the projections 26 with their sections running parallel to the arms 30. In this latching position, the leaf springs 32, which are supported on the bowl bottom 19 under pretension, exert a pretensioning force on the pushbutton 27 which is latched on the cover 10 by means of their latching hooks 31. The actuation stroke of the pushbutton 27 is limited by the interaction of the stop surface 24 with the underside facing it on the brackets 30, as a result of which the force that can be exerted by an operator on the pushbutton 13 via the pushbutton 27 is limited and damage to the pushbutton 13 is thus avoided is.
Zur Herstellung der Abdeckung 10 und der Drucktaste 27 haben sich vor allem im Kunststoffspritzgußverfahren verarbeitbare thermoplastische Kunststoffe bewährt. Thermoplastic materials which can be processed in the plastic injection molding process have proven particularly suitable for producing the cover 10 and the pushbutton 27.
