Description

Die Erfindung betrifft einen Rolladenpanzer für Kastenmöbel, bestehend aus über Filmscharniere gelenkig miteinander verbundenen Einzelprofilen, wobei die Einzelprofile trapezartige Hohlstäbe sind. Rolladen mit Einzelprofilen sind in vielfachen Ausführungsformen bekannt. So beschreibt die DE-A-21 11 317 einen Rolladen-Hohlprofilstab aus stranggepresstem Kunststoff, den Querschnitt aus mindestens einer in sieh geschlossenen Kammer mit zwei gleichsinnig gekrümmten, in geringem Abstand zueinander angeordneten Hauptwandungen besteht. Die Krümmungsmittelpunkte liegen dabei auf der der Rolladenwalze zugewandten Seite. Die Hauptwandungen sind durch Verbindungsstege miteinander verbunden, wobei einer der Verbindungsstege einen zur Rolladenwalze abgebogenen Haken aufweist, während an dem anderen Verbindungssteg eine mit einem Einhängeschlitz für den Haken des benachbarten Profilstabes versehene Gelenkkammer angeformt ist. Die Krümmung der Hauptwandungen und die Gelenkigkeit der Schlitz- Hakenverbindungen bestimmen bei diesem bekannten Stand der Technik die Größe des Aufwickelradius des Rolladenelementes. Mit derart aufgebauten Rolläden können sowohl Fenster- als auch Schranköffnungen verschlossen werden. Speziell für den Verschluß von Schranköffnungen sind nach dem Stand der Technik weiterhin Rolladen bekannt, welche aus einer rollfähigen Schichtstoffplatte mit quer zur Rollrichtung angeordneten Querversteifungen aufgebaut sind. Als Beispiel hierfür wird die DE-U-79 13 550 genannt. Derart aufgebaute Schrankrolläden haben den Nachteil, daß ihre Herstellung jeweils individuell für den einzelnen Anwendungsfall erfolgen muß. Eine nachträgliche Veränderung, z.B. eine Verlängerung, ist bei dieser Herstellungsmethode nicht mehr möglich.The invention relates to a roller shutter curtain for cabinet furniture, consisting of individual profiles articulated to one another via film hinges, the individual profiles being trapezoidal hollow bars. Roller shutters with individual profiles are known in multiple embodiments. For example, DE-A-21 11 317 describes a roller shutter hollow profile rod made of extruded plastic, the cross-section of which consists of at least one chamber closed with two equally curved main walls arranged at a short distance from one another. The centers of curvature lie on the side facing the roller shutter roller. The main walls are connected to one another by connecting webs, one of the connecting webs having a hook bent toward the roller shutter roller, while an articulated chamber provided with a suspension slot for the hook of the adjacent profile bar is formed on the other connecting web. In this known prior art, the curvature of the main walls and the articulation of the slot hook connections determine the size of the winding radius of the roller shutter element. With such roller shutters, both window and cabinet openings can be closed. Especially for the closure of cabinet openings, roller shutters are also known from the prior art, which are constructed from a rollable laminated board with transverse stiffeners arranged transversely to the rolling direction. DE-U-79 13 550 is mentioned as an example of this. Cabinet roller shutters constructed in this way have the disadvantage that their manufacture must be carried out individually for the individual application. A subsequent change, e.g. an extension is no longer possible with this manufacturing method.

Aus der EP-A-0 368 695 ist ein Einzelprofil für Rolladen bekannt, das aus zwei Halbprofilen besteht, welche annähernd symmetrisch aufgebaut und durch ein Filmscharnier miteinander verbunden sind.From EP-A-0 368 695 a single profile for roller shutters is known which consists of two half profiles which are constructed approximately symmetrically and are connected to one another by a film hinge.

Die Außenseite des einen Halbprofils weist eine T-förmige Verdickung auf, die halternd in eine Nut eines benachbarten Halbprofil eingreift. Dadurch wird eine starre Verbindung zwischen zwei benachbarten Halbprofilen geschaffen, wodurch der Rollradius derart aufgebauter Rolladenpanzer nachteilig vergrößert wird. Als weiterer Nachteil der bekannten Rolladenprofile ist herauszustellen, daß jeweils zwei Halbprofile an ihrer Sichtseite über eine Polymerbrücke als Filmscharnier miteinander verbunden sind. Dadurch lassen sich unansehnliche Übergänge im Sichtbereich zwischen dem harten Kunststoff der Halbprofile und dem weichen Kunststoff des Filmscharniers nicht vermeiden.The outside of one half profile has a T-shaped thickening which engages in a groove in an adjacent half profile. This creates a rigid connection between two adjacent half profiles, which disadvantageously increases the rolling radius of the roller shutter curtain constructed in this way. Another disadvantage of the known roller shutter profiles is that two half profiles are connected to each other on their visible side via a polymer bridge as a film hinge. As a result, unsightly transitions in the field of view between the hard plastic of the half profiles and the soft plastic of the film hinge cannot be avoided.

Hier setzt die Erfindung ein, die es sich zur Aufgabe gestellt hat, einen Rolladen für den Schrank- bzw. Möbelbau anzugeben, der aufbauend auf den Erkenntnissen des Standes der Technik auch eine nachträgliche Anpassung an die Vielzahl der gegebenen Einsatzmöglichkeiten beinhaltet.This is where the invention comes in, which has set itself the task of specifying a roller shutter for cabinet or furniture construction, which, based on the knowledge of the prior art, also includes a subsequent adaptation to the multitude of possible uses.

Erfindungsgemäß wird dazu vorgeschlagen, daß mehrere Einzelprofile über an deren schmaleren, von der Sichtseite abgewandten Basis als profilverbindende Polymerbrücken angeordnete Filmscharniere zu einem Rolladenelement verbunden sind, und daß an den freien Enden jedes Rolladenelementes einerseits ein Profil mit einer Nutenöffnung und andererseits ein Profil mit einer Feder zum Festlegen zweier Rolladenelemente aneinander angeformt sind.According to the invention it is proposed that several individual profiles are connected to a roller shutter element via film hinges arranged on their narrower base facing away from the visible side as profile-connecting polymer bridges, and that on the free ends of each roller shutter element on the one hand a profile with a groove opening and on the other hand a profile with a spring are molded together to define two roller shutter elements.

Die fertigungstechnische Zussammenfassung mehrerer Einzelprofile zu einem Rolladenelement, wobei die Einzelprofile jeweils über Filmscharniere miteinander verbunden sind, ergibt eine Arbeitserleichterung bei der Montage, verbunden mit einer erheblichen Zeiteinsparung. Anstelle des Einfädelns der Hakenstege in die zugeordneten Schlitzöffnungen der Folgeprofile bei jedem Einzelprofil oder jedem benachbarten Halbprofil muß dieser zeitaufwendige Arbeitsgang bei Verarbeitung des neuerungsgemäßen Rolladenelementes nur noch im Rahmen der Herstellungsbreiten dieser Rolladenelemente ausgeführt werden.The production-related combination of several individual profiles to form a roller shutter element, the individual profiles being connected to one another via film hinges, makes work easier during assembly, combined with considerable time savings. Instead of threading the hook webs into the assigned slot openings of the subsequent profiles for each individual profile or each adjacent half-profile, this time-consuming operation when processing the innovative roller shutter element only has to be carried out within the scope of the manufacturing width of these roller shutter elements.

Gegenüber den bekannten Rolladenelementen mit rollfähigen Folien und Querversteifungen bringt die Anwendung des erfindungsgemäßen Rolladenelementes den Vorteil, daß die Baulängen des Rolladens beliebig variiert werden können. Das einmal gefertigte Rolladenelement kann durch beliebiges Aneinanderfügen mehrerer solcher Elemente den erforderlichen Baugrößen ohne weiteres angepaßt werden.Compared to the known roller shutter elements with rollable foils and transverse reinforcements, the use of the roller shutter element according to the invention has the advantage that the overall lengths of the roller shutter can be varied as desired. The roller shutter element once manufactured can be easily adapted to the required sizes by joining several such elements together.

Vorteilhaft sind die Einzelprofile trapezartiger Hohlstäbe, an deren schmalerer, von der Sichtseite abgewandten Basis die Filmscharniere als profilverbindende Polymerbrücken angeordnet sind. Ferner besitzen die Einzelprofile an den Profilschenkeln im Anlagebereich einerseits eine Profilverdickung und andererseits eine Profileinschnürung zur Aufnahme der zugeordneten Profilverdickung. Durch diese Maßnahme wird eine zusätzliche Verfestigung des Rolladenpanzers in geschlossenem Zustand bewirkt.The individual profiles of trapezoidal hollow bars are advantageous, on the narrower base of which, facing away from the visible side, the film hinges are arranged as profile-connecting polymer bridges. Furthermore, the individual profiles on the profile legs in the contact area have on the one hand a profile thickening and on the other hand a profile constriction for receiving the assigned profile thickening. This measure causes the roller shutter curtain to additionally solidify in the closed state.

Die Nutenöffnung für die Verbindung zweier erfindungsgemäßer Rolladenelemente miteinander ist vorteilhaft in die Basis des außenliegenden Hohlstabes eingelassen. Hierbei ist es für den Gesamtaufbau günstig, daß die Basis des außenliegenden Hohlstabes um seine Wanddicke zurückversetzt ist. Die Wanddicke des Hohlstabes wird bei der Herstellung des Rolladenelementes gleichgesetzt mit der Wanddicke des die Feder tragenden Profils. Auf diese Weise wird mit der Herstellung der Nut-Feder-Verbindung ein im Umfang den anderen Einzelprofilen des Rolladenelementes völlig entsprechendes Verbindungsprofil geschaffen.The groove opening for connecting two roller shutter elements according to the invention to one another is advantageously embedded in the base of the external hollow bar. It is favorable for the overall structure that the base of the outer hollow rod is set back by its wall thickness. In the manufacture of the roller shutter element, the wall thickness of the hollow rod is equated with the wall thickness of the profile carrying the spring. In this way, with the production of the tongue and groove connection, a connection profile that is completely equivalent in scope to the other individual profiles of the roller shutter element is created.

Zur zusätzlichen Verfestigung kann der Hohlstab mit der Nutenöffnung einen die Profilschenkel verbindenden inneren Verstärkungssteg aufweisen.For additional strengthening, the hollow rod with the groove opening can have an inner reinforcing web connecting the profile legs.

Das zur Herstellung der Nut-Feder-Verbindung erforderliche Federprofil ist ein von seiner Basis abragendes, pilzkopfartiges Rastelement, welches im Bereich seiner größten Ausladung dicker ist als der lichte Durchgang der Nutenöffnung.The tongue profile required to produce the tongue and groove connection is a mushroom-like locking element which projects from its base and which is thicker in the area of its largest projection than the clear passage of the slot opening.

Dieses pilzkopfartige Rastelement kann von seinen Abmessungen her so gestaltet sein, daß es in die Nutenöffnung des zugeordneten Verbindungshohlstabes eingedrückt oder seitlich eingezogen werden kann.The dimensions of this mushroom-like locking element can be designed such that it can be pressed into the groove opening of the associated connecting hollow rod or drawn in laterally.

In diesem Zustand hintergreifen die aufeinander zugerichteten freien Enden der die Nutenöffnung begrenzenden Wandbereiche der Basis eines außenliegenden Hohlstabes die Außenbereiche des zugeordneten pilzkopfartigen Rastelementes in Form einer festen Halterung.In this state, the mutually facing free ends of the wall regions of the base of an outer hollow rod that delimit the groove opening engage behind the outer regions of the associated mushroom-shaped locking element in the form of a fixed holder.

In der Zeichnung ist das erfindungsgemäße Rolladenelement 1 im Querschnitt dargestellt. Das gezeigte Rolladenelement besitzt fünf gleichgroße Einzelprofile 2, 3, 4, 5, 6. Diese Einzelprofile 2, 3, 4, 5, 6 sind an ihrer Basis 21, 31, 41, 51, 61 jeweils über die Filmscharniere 22, 32, 42, 52 fest miteinander verbunden. Diese Verbindung erfolgt im Urformprozess bei der Herstellung der Einzelprofile. Hierzu wird das als Koextrusion bekannte Herstellungsverfahren angewendet, bei dem beispielsweise Kunststoffe verschiedener Härteeinstellungen in einem Arbeitsgang miteinander verbunden werden.In the drawing, the roller shutter element 1 according to the invention is shown in cross section. The roller shutter element shown has five individual sections 2, 3, 4, 5, 6 of the same size. These individual sections 2, 3, 4, 5, 6 are at their bases 21, 31, 41, 51, 61 each via the film hinges 22, 32, 42 , 52 firmly connected. This connection takes place in the original molding process during the manufacture of the individual profiles. For this purpose, the manufacturing process known as coextrusion is used, in which, for example, plastics of different hardness settings are connected to one another in one operation.

An den Profilschenkeln 23, 33, 43, 53, 63 besitzen die Einzelprofile 2, 3, 4, 5, 6 im Anlagebereich zueinander eine Profilverdickung 231, 331, 431, 531, 631. An den gegenüberliegenden Profilschenkeln 24, 34, 44, 54, 64 besitzen die Einzelprofile 2, 3, 4, 5, 6 auf der gleichen Höhe der Profilverdickungen 231, 331, 431, 531, 631 eine diesen entsprechend gestaltete Profileinschnürung 241, 341, 441, 541, 641. In dem in der Zeichnung dargestellten geschlossenen Zustand liegen die Profilverdickungen 231, 331, 431, 531 in den Profileinschnürungen 341, 441, 541, 641.On the profile legs 23, 33, 43, 53, 63, the individual profiles 2, 3, 4, 5, 6 have a thickened profile 231, 331, 431, 531, 631 in the contact area with one another. On the opposite profile legs 24, 34, 44, 54 , 64, the individual profiles 2, 3, 4, 5, 6 at the same height of the profile thickenings 231, 331, 431, 531, 631 have a constriction 241, 341, 441, 541, 641 designed accordingly. In the drawing shown in the drawing closed state, the profile thickenings 231, 331, 431, 531 lie in the profile constrictions 341, 441, 541, 641.

An die Basis 21 des Einzelprofils 2 ist über das Filmscharnier 72 die Basis 71 des Federprofils 7 angelenkt. Das Federprofil 7 ist ein pilzkopfartiges Rastelement mit abgerundetem Kopf 73 und von den Bereichen der größten Ausladung 74, 75 zur Basis 71 gradlinig aufeinander zulaufenden Verbindungsstegen 76, 77 besteht.The base 71 of the spring profile 7 is articulated to the base 21 of the individual profile 2 via the film hinge 72. The spring profile 7 is a mushroom-shaped locking element with a rounded head 73 and from the areas of the largest projection 74, 75 to the base 71 there are connecting webs 76, 77 which converge in a straight line.

Die gezeigte Darstellung dient lediglich als Beispiel für den Aufbau eines solchen Rastelementes. Andere Querschnittsformen dieser Raster mit gleichen Eigenschaften werden als unter das Schutzrecht fallend angesehen.The illustration shown serves only as an example for the construction of such a locking element. Other cross-sectional shapes of these grids with the same properties are considered to be covered by the property right.

Am gegenüberliegenden Ende des gezeigten Rolladenelementes 1 ist über das Filmscharnier 82 das die Nutenöffnung 85 enthaltende Profil 8 fest an das Einzelprofil 6 angelenkt. Die Nutenöffnung 85 ist in die Basis 81 des Profils 8 längsverlaufend eingelassen, so daß die Basisstege 811, 812 die Nutenöffnung 85 begrenzen. Die Basis 81 des Profils 8 ist um die Wanddicke der Basis 71 des Profils 7 zum Inneren des Profils 8 zurückversetzt, wobei der Stegbereich 842, an den das Filmscharnier 82 angelenkt ist, stehen gelassen worden ist. In den Profilschenkel 84 ist in Entsprechung zu den Einzelprofilen 2, 3, 4, 5, 6 die Profileinschnürung 841 eingelassen, in die in der gezeigten Darstellung die Profilverdickung 631 des vorausgehenden Einzelprofils 6 eingreift. Am gegenüberliegenden Profilschenkel 83 ist die Profilverdickung 831 angeformt, welche in die entsprechende Profileinschnürung des zugeordneten Einzelprofils eines angeordneten, in der Zeichnung nicht dargestellten zweiten Rolladenelementes eingreift.At the opposite end of the roller shutter element 1 shown, the profile 8 containing the slot opening 85 is articulated to the individual profile 6 via the film hinge 82. The groove opening 85 is let into the base 81 of the profile 8 so that the base webs 811, 812 delimit the groove opening 85. The base 81 of the profile 8 is set back by the wall thickness of the base 71 of the profile 7 to the inside of the profile 8, the web area 842 to which the film hinge 82 is articulated has been left standing. Corresponding to the individual profiles 2, 3, 4, 5, 6, the profile constriction 841 is embedded in the profile leg 84, in which the profile thickening 631 of the preceding individual profile 6 engages in the illustration shown. On the opposite profile leg 83, the profile thickening 831 is molded, which engages in the corresponding profile constriction of the associated individual profile of an arranged second roller shutter element, not shown in the drawing.

Das Profil 8 besitzt im Bereich des Beginns der Profileinschnürung 841 einen die Profilschenkel 83, 84 verbindenden inneren Verstärkungssteg 86. Dieser Verstärkungssteg 86 dient zur Erhöhung der Festigkeit des Profils 8.In the area of the beginning of the constriction 841, the profile 8 has an inner reinforcement web 86 connecting the profile legs 83, 84. This reinforcement web 86 serves to increase the strength of the profile 8.
