Description

Die Erfindung betrifft einen Kalender gemäß Oberbegriff des Anspruchs 1.The invention relates to a calendar according to the preamble of claim 1.

Ein Kalender dieser Art ist aus der FR-E-017 039 bekannt. Bei dieser bekannten Anordnung sind das Gehäuseunterteil und der Gehäusedeckel als aufeinander aufsteckbare, quaderförmige Wannen ausgebildet, die beide zur Bildung von Lagern für die Wickelwellen und diesen zugeordneten Niederhaltern mit von ihrem Rand ausgehenden Schlitzen versehen sind. Dies erschwert eine exakte, stoßfreie Lagerung der Wickelwellen und erschwert die Handhabung. Gleichzeitig ergibt die bekannte Anordnung ein vergleichsweise plumpes, sperriges, kastenförmiges Gehäuse.A calendar of this kind is known from FR-E-017 039. In this known arrangement, the lower housing part and the housing cover are designed as cuboidal troughs which can be plugged onto one another, both of which are provided with slots extending from their edge to form bearings for the winding shafts and holding-down devices associated therewith. This makes exact, shock-free mounting of the winding shafts difficult and makes handling more difficult. At the same time, the known arrangement results in a comparatively clumsy, bulky, box-shaped housing.

Die FR-A 4 37 024 zeigt einen ähnlichen Bandkalender mit einer quaderförmigen Wanne zur Aufnahme der Wickelwellen. Diese sind dabei jedoch in Bohrungen der Wannenseitenflanken gelagert, was die Herstellung und Montage erschwert.FR-A 4 37 024 shows a similar band calendar with a cuboid-shaped trough for receiving the winding shafts. However, these are stored in bores in the side walls of the tub, which complicates manufacture and assembly.

Die FR-A 818 337 zeigt einen Bandkalender mit durch eine Brücke miteinander verbundenen Trögen zur Aufnahme der Wickelwellen. Diese sind jeweils durch eine Feder in axialer Richtung beaufschlagt und damit in Drehrichtung reibschlüssig am zugeordneten Gehäuse gebremst. Diese bekannte Anordnung erweist sich jedoch als sehr kompliziert und aufwendig in der Herstellung und der Montage. Zudem sind die verwendeten Federn sehr störanfällig.FR-A 818 337 shows a band calendar with troughs connected to each other by a bridge for receiving the winding shafts. These are each acted upon by a spring in the axial direction and are thus frictionally braked in the direction of rotation on the associated housing. This well-known However, the arrangement proves to be very complicated and complex to manufacture and assemble. In addition, the springs used are very prone to failure.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, einen Massenartikel in Form eines Kalenders gattungsgemäßer Art mit einfachen und kostengünstigen Mittel so zu verbessern, daß sich eine handliche, kompakte und gleichzeitig ansehliche Bauweise sowie eine hohe Funktionssicherheit ergeben.Proceeding from this, it is therefore the object of the present invention to improve a mass-produced article in the form of a calendar of the generic type with simple and inexpensive means in such a way that a handy, compact and, at the same time, attractive design and high functional reliability result.

Diese Aufgabe wird erfindungsgemäß durch das Kennzeichen des Anspruchs 1 gelöst.This object is achieved by the characterizing part of claim 1.

Die erfindungsgemäßen Maßnahmen ergeben eine zuverlässige Lagerung und axiale Abstützung der Wickelwellen, was einen ruhigen Lauf erwarten läßt. Infolge der reibschlüssigen Kupplung der Wickelwellen mit dem Gehäuseunterteil wird außerdem sichergestellt, daß das Kalenderband in Form strammer Wicklungen auf die Wickelwellen aufgewickelt und im Bereich zwischen den Wickelwellen sauber gespannt werden kann, ohne daß eine selbsttätige Rückstellung und Lockerung erfolgen. Dies ermöglicht in vorteilhafter Weise nicht nur eine einfache und störungsfreie Handhabung, sondern auch eine platzsparende Unterbringung von eine vergleichsweise große Bandlänge speichernden Wickelballen. Es kann daher in vorteilhafter Weise ein vergleichsweise langes Kalenderband Verwendung finden, das einen vergleichsweise langen Kalenderzeitraum enthält. Außerdem lassen sich die obigen Vorteile auch bei Verwendung eines vergleichsweise steifen Kalenderbands erreichen, was eine hohe Qualität und Lebensdauer ermöglicht. Mit den erfindungsgemäßen Maßnahmen gelingt demnach eine beträchtliche Verbesserung des hier in Frage stehenden Massenartikels.The measures according to the invention result in reliable storage and axial support of the winding shafts, which can be expected to run smoothly. As a result of the frictional coupling of the winding shafts to the lower housing part, it is also ensured that the calendar tape can be wound onto the winding shafts in the form of tight windings and can be stretched cleanly in the area between the winding shafts without automatic resetting and loosening. This advantageously enables not only simple and trouble-free handling, but also space-saving accommodation of wrapping bales that store a comparatively large length of tape. A comparatively long calendar tape that contains a comparatively long calendar period can therefore advantageously be used. In addition, the above advantages can also be compared when using one stiff calendar tape, which enables high quality and durability. The measures according to the invention accordingly result in a considerable improvement in the mass article in question here.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben und aus der nachstehenden Beispielsbeschreibung anhand der Zeichnung entnehmbar.Advantageous refinements and expedient further training of the higher-level measures are specified in the subclaims and can be found in the following description of the examples with reference to the drawing.

In der nachstehend beschriebenen Zeichnung zeigen:

In the drawing described below:
Figure 1
2 shows a longitudinal section through a desk calendar according to the invention in an exploded view,
Figure 2
a plan view of the lower housing part and
Figure 3
a plan view of the inside of the housing cover.

Der der Figur 1 zugrundeliegende Tischkalender enthält ein mit kalendarischen Daten bedrucktes, in Form einer strichpunktierten Linie angedeutetes Kalenderband 1, das mit seinen Enden an Wickelwellen 2 befestigt ist. Das Kalenderband 1 wird durch Drehen der Wickelwellen 2 von der einen Wickelwelle ab- und auf die andere Wickelwelle aufgewickelt. Die dabei entstehenden Wickelballen sind ebenfalls durch strichpunktierte Linien angedeutet.The desk calendar on which FIG. 1 is based contains a calendar tape 1 printed with calendar data and indicated in the form of a dash-dotted line, the ends of which are attached to winding shafts 2. The calendar tape 1 is turned by rotating the winding shafts 2 from one winding shaft and onto the other winding shaft wound up. The resulting wrapping bales are also indicated by dash-dotted lines.

Die Wickelwellen 2 sind in einem Gehäuse aufnehmbar. Dieses besteht aus einem Gehäuseunterteil 3 und einem Gehäusedeckel 4. Das Gehäuseunterteil ist mit zwei durch eine Brücke 5 voneinander distanzierten Trögen 6 versehen, in denen die Wickelwellen 2 samt den auf diese aufwickelbaren Wickelballen aufnehmbar sind. Die Brücke 5 bildet eine Unterlage, auf der das Kalenderband 1 mit seinem von den Wickelwellen 1 abgewickelten Bereich läuft. Zur Bewerkstelligung einer seitlichen Führung des über die Brücke 5 hinweglaufenden Kalenderbands 1 ist die Brücke 5 mit seine Laufbahn seitlich begrenzenden Führungsleisten 7 versehen. Die Wickelwellen 2 sind mit die hierauf aufnehmbaren Wickelballen seitlich begrenzenden, mit den Führungsleisten 7 fluchtenden Flanschen 8 versehen.The winding shafts 2 can be accommodated in a housing. This consists of a lower housing part 3 and a housing cover 4. The lower housing part is provided with two troughs 6 spaced apart from one another by a bridge 5, in which the winding shafts 2 together with the winding bales which can be wound thereon can be received. The bridge 5 forms a base on which the calendar band 1 runs with its area which is unwound from the winding shafts 1. To accomplish lateral guidance of the calendar tape 1 running over the bridge 5, the bridge 5 is provided with guide rails 7 which laterally delimit its track. The winding shafts 2 are provided with the winding bales which can be laterally delimited thereon and which are aligned with the guide strips 7, with flanges 8.

Die Wickelwellen 2 sind, wie am besten aus Figur 2 erkennbar ist, mit einem Ende aus dem jeweils zugeordneten Trog 6 herausgeführt und mit einem außerhalb des Gehäuses angeordneten Betätigungsknopf 9 versehen. Die betreffende Trogstirnwand ist mit einer vom Trogrand 2 ausgehenden, schlitzförmigen Durchgangsausnehmung 10 versehen, die, wie Figur 2 zeigt, vom den Betätigungsknopf 9 tragenden Ende der zugehörigen Wickelwelle 2 durchsetzt wird. Die Durchgangsausnehmung 10 ist in Figur 1 unten angedeutet. Die gegenüberliegende Trogstirnseite ist, wie in Figur 1 oben angedeutet ist, mit einem vom Trogrand ausgehenden, nur nach innen offenen Nut 11 versehen, in die, wie Figur 2 zeigt, ein stummelförmiges Ende der zugehörigen Wickelwelle 2 eingreift. Zur Lagesicherung der in die Ausnehmung 10 bzw. Nut 11 eingelegten Wickelwellen 2 sind an den Gehäusedeckel 4, wie die Figuren 1 und 3 zeigen, Niederhalter 12 angeformt, die bei auf das Gehäuseunterteil 3 aufgesetztem Gehäusedeckel 4 in die stirnseitige Durchgangsausnehmung 10 bzw. Nut 11 eingreifen und die dort eingelegten Wickelwellen 2 gegen Ausheben sichern. Die Niederhalter 12 sind laschenförmig ausgebildet und an ihren inneren Enden mit konkaven Lagerausnehmungen 13 versehen. Die unterteilseitige Durchgangsausnehmung 10 bzw. Nut 11 sind mit zu den konkaven Lagerausnehmungen 13 symmetrischen Lagerflächen versehen, wodurch sich eine Abstützung der Wickelwellen 2 auf ihrem ganzen Umfang ergibt.As can best be seen from FIG. 2, the winding shafts 2 are led out of the respectively assigned trough 6 with one end and provided with an actuating button 9 arranged outside the housing. The trough end wall in question is provided with a slit-shaped passage recess 10 starting from the trough edge 2 and, as shown in FIG. 2, penetrated by the end of the associated winding shaft 2 carrying the actuating button 9. The passage recess 10 is indicated in Figure 1 below. The opposite side of the trough, as indicated in FIG. 1 above, is provided with a groove 11, which starts from the edge of the trough and is only open inwards and into which, as shown in FIG. 2, a stub-shaped one Engages end of the associated winding shaft 2. To secure the position of the winding shafts 2 inserted into the recess 10 or groove 11, hold-down devices 12 are integrally formed on the housing cover 4, as shown in FIGS. 1 and 3 intervene and secure the winding shafts 2 inserted there against lifting. The hold-down devices 12 are tab-shaped and are provided with concave bearing recesses 13 at their inner ends. The lower-side passage recess 10 or groove 11 are provided with bearing surfaces symmetrical to the concave bearing recesses 13, which results in support of the winding shafts 2 over their entire circumference.

Die Wickelwellen 2 sind mit dem sie aufnehmenden Gehäuseunterteil 3 reibschlüssig gekuppelt, um eine Lockerung des Kalenderbands 1 bzw. der Wickelballen zu verhindern. Hierzu können ein Flansch 8 oder beide Flansche 8 reibschlüssig, d.h. mit Pressung an der Innenseite der jeweils benachbarten Trogstirnwand anliegen. Zur Verbesserung der Reibung können ein Reibbelag oder eine reibbelagähnliche Reiboberfläche vorgesehen sein. Im dargestellten Ausführungsbeispiel ist zur Bewerkstelligung des erwünschten Reibschlusses in den Spalt zwischen dem betätigungsknopfseitigen Flansch 8 und der benachbarten Trogstirnwand ein auf dem betreffenden Wickelwellenende aufgenommener O-Ring 14 aus gummielastischem Material eingelegt. Der Durchmesser des O-Rings 14 ist etwas grösser als die Spaltweite. Der O-Ring 14 liegt dementsprechend mit Vorspannung am benachbarten Flansch 8 und der Trogstirnwand an. Die Gegenkraft wird über das gegenüberliegende, in eine Nut 11 eingreifende, stummelförmige Wellenende auf die gegenüberliegende Trogstirnwand übertragen.The winding shafts 2 are frictionally coupled to the housing lower part 3 receiving them in order to prevent the calendar band 1 or the winding bale from loosening. For this purpose, a flange 8 or both flanges 8 can be in frictional engagement, ie with pressure, on the inside of the adjacent trough end wall. A friction lining or a friction surface similar to a friction lining can be provided to improve the friction. In the illustrated embodiment, in order to achieve the desired frictional engagement, an O-ring 14 made of rubber-elastic material is inserted into the gap between the flange 8 on the actuating button side and the adjacent trough end wall. The diameter of the O-ring 14 is slightly larger than the gap width. The O-ring 14 is accordingly with prestress on the adjacent flange 8 and the trough end wall. The opposing force is in a groove 11 engaging, stubby shaft end transferred to the opposite trough end wall.

Das Kalenderband 1 kann durch eine Klebverbindung etc. an den Wickelwellen 2 befestigt sein. Im dargestellten Ausführungsbeispiel ist eine Klemmhalterung vorgesehen. Hierzu sind die Wickelwellen 2 außerhalb ihres Betätigungsknopfes 9 auf ihrer ganzen Länge durchgehend geschlitzt, so daß sich praktisch zwei entlang eines Mittelschlitzes 15 aneinander anpreßbare Backen ergeben, zwischen denen ein zugeordnetes Ende des Kalenderbands 1 einklemmbar ist. Durch den Schlitz 15 werden auch die Flansche 8 geteilt.The calendar tape 1 can be attached to the winding shafts 2 by an adhesive connection etc. In the illustrated embodiment, a clamp bracket is provided. For this purpose, the winding shafts 2 are continuously slotted along their entire length outside their actuation button 9, so that practically two cheeks can be pressed against one another along a central slot 15, between which an associated end of the calendar tape 1 can be clamped. The flanges 8 are also divided by the slot 15.

Der Gehäusedeckel 4 ist durch Schnappverschluß am Gehäuseunterteil festlegbar. Hierzu ist der Gehäusedeckel 4, wie aus den Figuren 1 und 3 entnehmbar ist, mit einem um]aufenden Rahmen 16 versehen, der nach innen vorspringende Rastzähne 17 trägt. Das Gehäuseunterteil 3 ist, wie am besten aus Figur 2 erkennbar ist, mit seitlich vorspringenden Randleisten 18 versehen, unter welche die Rastzähne 17 beim Aufsetzen des Gehäusedeckels 4 einrasten können. Der vorgesehene Schnappverschluß ergibt einerseits eine zuverlässige, gegenseitige Sicherung der beiden Gehäuseteile und gewährleistet andererseits auch eine einfache, gegenseitige Lösbarkeit, womit das Gehäuse beispielsweise zum Austausch des Kalenderbands 1 geöffnet werden kann.The housing cover 4 can be fixed by a snap lock on the lower housing part. For this purpose, the housing cover 4, as can be seen from FIGS. 1 and 3, is provided with a frame 16 which rises and bears inwardly projecting locking teeth 17. As can best be seen from FIG. 2, the lower housing part 3 is provided with laterally projecting edge strips 18, under which the latching teeth 17 can snap when the housing cover 4 is put on. The provided snap lock results on the one hand in a reliable, mutual securing of the two housing parts and on the other hand also ensures simple, mutual releasability, with which the housing can be opened, for example, for exchanging the calendar tape 1.

Der Gehäusedeckel 4 ist, wie die Figuren 1 und 3 weiter erkennen lassen, mit einem der unterteilseitigen Brücke 5 zugeordneten Sichtfenster 19 versehen, in dessen Bereich das über die Brücke 5 hinweg-geführte Kalenderband 1 sichtbar ist. Im Bereich der Tröge 6 wird das Gehäuseunterteil durch den Gehäusedeckel 4 verschlossen. Um eine Tagesanzeige zu ermöglichen, sind das Sichtfenster 19 durchquerende, eine Zeile 20 begrenzende Stege 21 vorgesehen. Auf diesen ist ein rahmenförmiger Reiter 22 verschiebbar aufgenommen, der eine kästchenförmige Ausnehmung 23 enthält. Der Reiter 22 hintergreift die Stege 21, d. h. wird von der Gehäuseinnenseite her aufgesteckt, wodurch sichergestellt ist, daß der Reiter 22 durch die infolge ihrer geringen Stärke elastischen Stege 21 auf die Unterlage in Form des über die Brücke 5 gezogenen Kalenderbands 1 gedrückt wird und dementsprechend nicht verlorengehen kann. Durch seitliches Verschieben des Reiters 22 läßt sich über der Länge der Zeile 20 eine spaltenförmige Einteilung erreichen.As can further be seen from FIGS. 1 and 3, the housing cover 4 is provided with one of the lower-side bridges 5 assigned viewing window 19, in the area of which the calendar band 1 guided over the bridge 5 is visible. In the area of the troughs 6, the lower housing part is closed by the housing cover 4. In order to enable a daily display, webs 21 crossing the viewing window 19 and delimiting a line 20 are provided. On this a frame-shaped tab 22 is slidably received, which contains a box-shaped recess 23. The tab 22 engages behind the webs 21, that is to say is plugged on from the inside of the housing, thereby ensuring that the tab 22 is pressed onto the base in the form of the calendar tape 1 pulled over the bridge 5 by the elastic webs 21 due to its low thickness and accordingly cannot be lost. By moving the tab 22 laterally, a columnar division can be achieved over the length of the line 20.

Um den Sichtbereich besonders hervortreten zu lassen, ist die Oberseite des Gehäuseunterteils einschließlich der die Tröge 6 miteinander verbindenden Brücke 5 konvex gewölbt. Der Gehäusedeckel 4 besitzt eine hierzu parallele Wölbung. Hierdurch wird erreicht, daß der die Zeile 20, entlang welcher der Reiter 22 verschiebbar ist, enthaltende Bereich besonders hervortritt und ins Auge springt.In order to make the field of vision stand out, the upper side of the lower housing part, including the bridge 5 connecting the troughs 6, is convexly curved. The housing cover 4 has a curvature parallel to this. This ensures that the area containing the line 20 along which the tab 22 is displaceable particularly stands out and is eye-catching.

Zur Bewerkstelligung einer stehenden Anordnung des vorliegenden Kalenders sind an der Rückseite der Brücke 5 eine Einstecknut 24 begrenzende Vorsprünge 25 angeformt. In die Einstecknut 24 kann eine Sütztplatte 26 zur Bewerkstelligung einer rückwärtigen Abstützung eingesteckt werden. Die Vorsprünge 25 und die Stützplatte 26 können dabei so gestaltet sein, daß sich ein gegenseitiger Formschluß ergibt. Hierzu können beispielsweise in stützplattenseitige Rostkerben einrastende Rastzähne vorgesehen sein. Es wäre aber auch denkbar, im Bereich des oberen Trogs 6 eine Aufhängeeinrichtung vorzusehen, um die vorliegende Anordnung auch als Wandkalender verwenden zu können.In order to accomplish a standing arrangement of the present calendar, protrusions 25 delimiting an insertion groove 24 are formed on the back of the bridge 5. A support plate 26 can be inserted into the insertion groove 24 to accomplish a rear support become. The projections 25 and the support plate 26 can be designed so that there is a mutual positive engagement. For this purpose, for example, latching teeth can be provided which engage in grate notches on the support plate side. However, it would also be conceivable to provide a suspension device in the area of the upper trough 6 in order to be able to use the present arrangement as a wall calendar.

Sämtliche Bauteile in Form von Gehäuseunterteil 3, Gehäusedeckel 4, Wickelwellen 2, Reiter 22 und Stützplatte 26 können als Spritzgußformlinge aus Kunststoff hergestellt werden. Zur Bildung des O-Rings 14 findet zweckmäßig gummielastisches Material Verwendung.All components in the form of lower housing part 3, housing cover 4, winding shafts 2, tabs 22 and support plate 26 can be produced as injection molded plastic parts. Rubber-elastic material is expediently used to form the O-ring 14.
