Abstract

2.1 Known assembly display cases, which comprise merely horizontal frames and vertical panels placed in grooves of the same, exhibit sufficient stability only when the panels are inserted into the grooves using great force. For the rapid and simple assembly of a display case this is too laborious. 2.2 It is proposed that the grooves be assigned resilient clamping lips which act as a type of barb when forces are exerted on the panels to be inserted which try to remove the panels from the grooves again. 2.3 use for assembly display cases in fair and exhibition construction. <IMAGE>

Description

Die Erfindung betrifft eine Aufbauvitrine, bei der mindestens zwei im Abstand übereinander angeordnete horizontale Rahmen mit auf der Ober- und/oder Unterseite umlaufenden Nuten vorgesehen sind, in die Platten gleicher Höhe vertikal eingesetzt und gehalten sind.The invention relates to a display case in which at least two horizontal frames spaced one above the other provided with circumferential grooves on the top and / or bottom are inserted vertically into the panels of the same height and are kept.

Eine Aufbauvitrine dieser Art ist bekannt (DE-U-82 10 244). Bei diesen Bauarten sind Holzrahmen vorgesehen, die auf drei ihrer Seiten nach oben und unten je eine umlaufende Nut gleicher Tiefe und Stärke aufweisen, die dazu dient, Glasplatten mit einer bestimmten Stärke aufzunehmen, die in die Nuten eingeschoben und in diesen Nuten verklemmt werden. Auf der späteren Vorderseite besitzen die Rahmen eine doppelt so breite Nut, in die Einsatzleisten mit zwei nebeneinanderliegenden Nuten eingefügt sind, deren Breite wiederum der Breite der ersten Nuten entsprechen. Diese Doppelnut dient dazu, Glasplatten in der Form von Schiebetüren aufzunehmen, die in den Doppelnuten aneinander vorbeigleiten können.A display case of this type is known (DE-U-82 10 244). In these designs, wooden frames are provided, which are based on three their sides up and down each have a circumferential groove the same Have depth and strength that serves glass plates with a certain strength to take up in the grooves inserted and jammed in these grooves. On the later frames have a double wide groove, in the insert strips with two side by side Grooves are inserted, the width of which in turn is the width correspond to the first grooves. This double groove is used Record glass plates in the form of sliding doors that in the double grooves can slide past each other.

Die Rahmen besitzen außerdem auf der nach innen gerichteten Seite einen umlaufenden Absatz, auf dem weitere Platten als Boden oder Decken der Vitrine aufgelegt werden können. Diese Bauarten erlauben zwar den Aufbau einer Vitrine ausschließlich aus umlaufenden Rahmen und vertikal stehenden Platten. Nachteilig ist aber, daß die Platten, die nicht als Schiebetüren verwendet werden sollen, entweder nur sehr schwer in die zugeordneten Nuten eingefügt werden können, was unter Umständen, insbesondere wenn ein Einschlagen der Platten mit einem Gummihammer erforderlich wird, zu einem Bruch der Glasplatten, insbesondere bei einer späteren Demontage führt. Sind die Abmessungen dagegen so gewählt, daß die vertikalen Glasplatten mehr oder weniger mit Spiel in den Rahmen geführt sind, dann ist zwar der Zusammenbau sehr einfach, der Halt einer solchen Vitrine ist aber für den praktischen Einsatz zu gering. Jede Belastung der Vitrine, die nicht senkrecht nach unten erfolgt, beispielsweise Zug auf eine der Platten, kann zum Zusammenfallen der Vitrine führen.The frames also have an inward facing Page a circumferential paragraph on which other plates as Floor or ceiling of the showcase can be placed. These designs only allow the construction of a display case from surrounding frames and vertical ones Plates. The disadvantage is that the plates that are not considered Sliding doors are to be used, either only very much what can be difficult to insert into the associated grooves under certain circumstances, especially if the panels are knocked in with a rubber mallet is required to break of the glass plates, especially during later disassembly leads. However, the dimensions are chosen so that the vertical Glass plates more or less with play in the frame then assembly is very simple Holding such a display case is for practical use too low. Any load on the showcase that is not vertical down, for example, train on one of the Plates can cause the display case to collapse.

Aus der US-A-4 979 078 ist allerdings eine Vitrine bekannt, bei der in eine umlaufende Ausnehmung eines Grundkastens ein Kunststoffprofil zur Halterung von Glasplatten eingesetzt ist, das an seinen beiden nach oben ragenden Schenkeln jeweils mit einer dachförmigen, nach beiden Seiten abragenden Lippenanordnung versehen ist, von denen die inneren Lippenteile sich beim Einschieben der Glasplatten der Vitrine nach unten biegen und somit für einen Halt der Platten in dem nutenförmigen Profil auch gegen Herausziehen sorgen. Gesonderte Maßnahmen allerdings, die ein besonders leichtes Einschieben der Platten ermöglichen, ein Wiederherausziehen dagegen verhindern, sind dort nicht vorgesehen.However, a display case is known from US-A-4 979 078, in the in a circumferential recess of a basic box Plastic profile used to hold glass plates is that on its two upstanding legs with a roof-shaped, protruding on both sides Lip arrangement is provided, of which the inner lip parts itself when inserting the glass plates of the showcase bend below and thus for a hold of the plates in the groove-shaped Also ensure that the profile is not pulled out. Separate However, measures that make insertion particularly easy enable the plates to be prevented from being pulled out, are not provided there.

Der Erfindung liegt die Aufgabe zugrunde, eine Aufbauvitrine der eingangs genannten Art so auszugestalten, daß eine einfache Montage der Vitrine ohne Zuhilfenahme von Werkzeugen möglich ist, ohne daß jedoch die Gefahr auftritt, daß der Zusammenhalt der zunächst zusammengesteckten Bauteile gefährdet ist. The invention has for its object a display case of the type mentioned in such a way that a simple The display case can be assembled without the use of tools is, but without the risk of cohesion of the components that were initially plugged together is.

Zur Lösung dieser Aufgabe wird eine Aufbauvitrine gemäß Anspruch 1 vorgeschlagen.To solve this problem proposed a display case according to claim 1.

Durch diese Ausgestaltung wird die Anbindung der Klemmlippen am Nutrand sehr elastisch, so daß das Einschieben der Platten ohne nennenswerten Widerstand erfolgen kann. Die Klemmlippen wirken im übrigen in der Art von Widerhaken, die zwar das Einsetzen der Platten ermöglichen, deren Herausnahme aus dem Nuten aber nicht oder nur äußerst schwer und unter Zuhilfenahme besonderer Maßnahmen möglich macht.This configuration makes the connection of the clamping lips very elastic at the edge of the groove so that the panels can be pushed in can be done without any significant resistance. The clamping lips otherwise act in the manner of barbs, which indeed Allow insertion of the plates, their removal from the But not grooving or only extremely difficult and with the help makes special measures possible.

Dabei wird zweckmäßigerweise vorgesehen, daß die Weite der die Klemmlippe enthaltenden Nut um ein bestimmtes Maß größer ist als die Stärke der Platten, das dabei so auf die Eigenschaften der Klemmlippe abzustimmen ist, daß diese, wenn sie bei eingeschobener Platte an dieser anliegt, aufgrund der zwischen ihr und der Platte auftretenden Reibung, die wiederum abhängig ist von den Reibungskoeffizienten und von der durch die Elastizität der Lippe bewirkten Andrückkraft, ausreichend fest gehalten ist, um ein Abgleiten der Platte an der Klemmlippe zu verhindern. Die Klemmlippe wird daher bei Zug auf eine der Platten in sich verformt oder gestaucht und drückt daher mit noch größerer Kraft und unter Erzeugung größerer Reibungskräfte gegen die Platte. Durch diese Ausgestaltung tritt der vorher erwähnte Widerhakeneffekt ein, der hier dazu ausgenützt wird, um die einmal eingeschobenen Platten auch sicher in den Nuten des Rahmens zu halten.It is conveniently provided that the width of the the groove containing the clamping lip is larger by a certain amount is as the strength of the panels, so doing so on the properties The pinch lip is to be tuned when this when the plate is inserted, due to the friction occurring between it and the plate, which in turn depends on the coefficient of friction and the sufficient pressure due to the elasticity of the lip is firmly held to slide off the plate to prevent the pinch lip. The clamping lip is therefore at Train on one of the plates deformed or compressed and therefore presses with even greater force and with greater production Frictional forces against the plate. Through this configuration the barb effect mentioned above occurs here is used to the inserted plates also hold securely in the grooves of the frame.

In Weiterbildung der Erfindung kann bei einer ersten Ausführungsform, die sich in der Praxis bewährt hat, der bewegliche Teil der Klemmlippe deren freies Ende bilden. Die Klemmlippe steht daher mit einem zum Nutboden gerichteten Ende in die Nut herein. Wenn sie ein gewölbtes, zur zugeordneten Wand der Nut hin gebogenes Profil bildet und eine im Bereich des freien Endes auf der in die Nut hereingerichteten Seite an die Klemmlippe gelegte Tangente etwa parallel zu der Befestigungswand für die Klemmlippe verläuft, dann bildet die Klemmlippe mit der gegenüberliegenden Nutwand eine Einführschräge für die einzusetzenden Platten, weicht beim Einsetzen der Platten elastisch aus, und liegt dann aber zur Bildung des Widerhakeneffektes mit dem Bereich des freien Endes an der Platte an.In a development of the invention, in a first embodiment, which has proven itself in practice, the mobile one Form part of the clamping lip with its free end. The The clamping lip is therefore with one end facing the groove bottom into the groove. If it is a domed, assigned to Wall of the groove forms a curved profile and one in the area of the free end on the one set in the groove Tangent placed on the side of the clamping lip approximately parallel to the Fastening wall for the clamping lip runs, then forms the Clamping lip with the opposite groove wall an insertion bevel for the panels to be used, gives way when inserting of the plates from elastic, and then lies for formation of the barb effect with the area of the free end the plate.

Die Unteransprüche kennzeichnen eine Möglichkeit, durch die auch zwei Klemmlippen vorgesehen werden können. Bei allen Ausführungsformen hat es sich als vorteilhaft erwiesen, die Rahmen und die Klemmlippen aus Kunststoff herzustellen, die Klemmlippen an die Nutwandungen einstückig anzuformen und für die Rahmen ein Hart-PVC und für die Klemmlippen ein Weich-PVC zu verwenden. Es hat sich gezeigt, daß sich solche Rahmen wirtschaftlich herstellen lassen.The subclaims indicate a possibility through which two clamping lips can also be provided. At all Embodiments have proven to be advantageous Frame and the clamping lips made of plastic that To form clamping lips on the groove walls in one piece and for the frames are made of hard PVC and soft PVC for the clamping lips to use. It has been shown that such frames Have it manufactured economically.

In der Fig. 1 sind Aufbauvitrinen 1 und 2 gezeigt, die jeweils ausschließlich aus horizontal angeordneten Rahmen 3 und aus vertikal in Nuten derselben eingeschobenen Platten, beim Ausführungsbeispiel Glassplatten 4, bestehen. Die Glasplatten weisen dabei, da der Rahmen rechteckig ausgebildet ist, unterschiedliche Längenabmessungen auf, sind aber alle in ihrer Höhe gleich ausgebildet. Bein Ausführungsbeispiel der Fig. 1 sind die Platten 4, wie später noch erläutert werden wird, in innen am Rahmen 3 umlaufende Nuten 5 eingesteckt, während zusätzliche Glasplatten 7 in äußere Nuten 6 eingeführt sind. Diese Glasplatten 7 dienen, da die Nuten 6 anders als die Nuten 5 ausgebildet sind, als Schiebetüren für die Regale 1 und 2.In Fig. 1 showcases 1 and 2 are shown, each exclusively from horizontally arranged frames 3 and from plates inserted vertically into grooves of the same, when Embodiment glass plates 4 exist. The glass plates have different, since the frame is rectangular Length dimensions, but are all in height equally trained. 1 are the embodiment of FIG the plates 4, as will be explained later, inside on the frame 3 circumferential grooves 5 inserted, while additional Glass plates 7 are inserted into outer grooves 6. These glass plates 7 serve because the grooves 6 differently than the grooves 5 are designed as sliding doors for shelves 1 and 2.

Die Fig. 3 zeigt, daß jeder der Rahmen 3 aus einem aus Kunststoff hergestellten Profil besteht, das nach oben und nach unten weisende Nuten 5 und 6 aufweist, und außerdem mit einem nach innen gerichteten umlaufenden Absatz 8 versehen ist, der in nicht näher erläuterter, weil bekannter Weise, zum Auflegen von Boden oder Deckenplatten zur Unterteilung der Vitrinen 1 und 2 in verschieden hohe Fächer dient.Fig. 3 shows that each of the frames 3 made of a plastic manufactured profile, the up and down having grooves 5 and 6 pointing below, and also with a is provided inward circumferential paragraph 8, the in a manner that is not explained in detail because it is known, for hanging up of floor or ceiling panels for dividing the showcases 1 and 2 in subjects of different heights.

Aus den Figuren 3 und 3a wird deutlich, daß die innere umlaufende Nut 5 auf der Innenseite mit einer in die Nut hereinragenden Klemmlippe 9 versehen ist, die am oberen Rand der Nutwand 10 einteilig angeformt ist, und zwar in einem Bereich 10a, der schmaler als die übrige Breite der Wand 10 ist und der durch eine Schräge 10b von dem Verlauf der Wand 10 nach außen abgesetzt ist. Die innere Wand 11, die auch die Zwischenwand zwischen den Nuten 5 und 6 bildet, besitzt beim Ausführungs beispiel nach den Figuren 3a und 4 keine Klemmlippe. Natürlich währe es auch möglich, dort noch zusätzlich eine Klemmlippe vorzusehen.From Figures 3 and 3a it is clear that the inner circumferential Groove 5 on the inside with one protruding into the groove Clamping lip 9 is provided at the top of the Groove wall 10 is formed in one piece, in one area 10a, which is narrower than the remaining width of the wall 10 and the through a slope 10b from the course of the wall 10 to the outside is discontinued. The inner wall 11, which is also the partition forms between the grooves 5 and 6, has the execution example according to Figures 3a and 4 no clamping lip. Naturally it would also be possible to have an additional clamping lip there to provide.

Aus der Darstellung der Fig. 3 ergibt sich im übrigen auch, daß eine im Bereich des freien Endes 9a an die Innenseite 9b der Klemmlippe 9 gelegte Tangente 25 etwa parallel zur Wand 10 verläuft. 3 also shows that one in the area of the free end 9a to the inside 9b of the Clamping lip 9 tangent 25 placed approximately parallel to wall 10 runs.

Die Breite b der Nut 5 ist, wie Fig. 4 deutlich werden läßt, größer als die Dicke a der Platten 4 gewählt. Die Figuren 3a und 4 zeigen, daß die Klemmlippe 9, die im Bereich ihrer Befestigungsstelle am Wandteil 10a dicker als an ihrem freien Ende 9a ist, als ein kreisbogenartig gewölbtes Profil ausgebildet ist, so daß zwischen der Wand 11 und ihrer nach innen gerichteten Seite 9b zum Nutboden 5a hin ein immer enger werdender Spalt entsteht. Die beim Ausführungsbeispiel gezeigten Rahmen 3 sind aus einem Hart-PVC als extrudierte Profile hergestellt. Die Klemmlippen 9 bestehen aus einem Weich-PVC, das beim Ausführungsbeispiel eine Härte von 66 Shore im Vergleich zu 80 Shore des Hart-PVCs des Rahmens 3 besitzt. Die Klemmlippe 9 ist wesentlich elastischer als das Hart-PVC des Übrigen Rahmens 3. Sie ist im Bereich 10a einstückig mit an das Rahmenprofil extrudiert. Die Rahmen selbst werden dadurch gebildet, daß die extrudierten Profile auf Gehrung geschnitten und miteinander verschweißt werden.The width b of the groove 5 is, as can be seen in FIG. 4, chosen larger than the thickness a of the plates 4. Figures 3a and 4 show that the clamping lip 9, which in the area of their Fastening point on the wall part 10a thicker than on its free End 9a is formed as an arcuate profile is so that between the wall 11 and its inside directed side 9b to the groove bottom 5a an increasingly narrow gap is created. The shown in the embodiment Frame 3 are made of hard PVC as extruded profiles manufactured. The clamping lips 9 consist of a soft PVC, that in the exemplary embodiment a hardness of 66 shore in comparison owns to 80 Shore of frame 3 rigid PVC. The Clamping lip 9 is much more elastic than the hard PVC of the Other frame 3. It is in one piece in the area 10a with the Extruded frame profile. This will make the frames themselves formed that the extruded profiles are mitred and welded together.

Die Figuren 3a und 4 machen deutlich, daß beim Einschieben einer Platte 4 in die offene Seite der Nut 5 die Klemmlippe 9 elastisch nach außen ausweicht, bis in die in der Fig. 4 gezeigte Endlage, in der sie mit einem Teil ihrer Oberfläche 9b unter einer durch die elastische Verformung bedingten Kraft an der zugeordneten Seite der Platte 4 anliegt. Die Elastizitätseigenschaften des Weich-PVCs der Klemmplippe 9 sind dabei so gewählt, daß die zwischen Klemmlippe 9 und der Platte 4, beispielsweise einer Glasplatte, auftretende Haftreibung, die bestimmt wird durch die elastische Andrückkraft und die Reibungskoeffizienten, groß genug ist, um ein Abgleiten der Platte 4 an der Klemmlippe 9 zu verhindern, wenn auf die Platte 4 eine Zugkraft in Richtung des Pfeiles 12 ausgeübt wird. Die Klemmlippe 9 wird daher beim Auftreten einer solchen Kraft versucht sein, sich im Uhrzeigersinn zu verschwenken. Dadurch drückt sie sich aber noch mit einer größeren Kraft an die Platte 4 an und verhindert so das Herausziehen der Platte 4. Figures 3a and 4 make it clear that when inserting a plate 4 in the open side of the groove 5, the clamping lip 9 resiliently dodges outwards, into that shown in FIG. 4 End position in which part of its surface 9b under a force caused by the elastic deformation the assigned side of the plate 4 abuts. The elasticity properties the soft PVC of the clip 9 are so chosen that between the clamping lip 9 and the plate 4, for example a glass plate, static friction that occurs is determined by the elastic pressure and the Coefficient of friction, is large enough to slip off Prevent plate 4 on the clamping lip 9 when on the plate 4 a tensile force is exerted in the direction of arrow 12. The Clamping lip 9 is therefore when such a force occurs be tempted to turn clockwise. Thereby but it presses itself against the with a greater force Plate 4 and thus prevents pulling out of plate 4.

Es hat sich bei einem Ausführungsbeispiel nach den Figuren 1 bis 4 gezeigt, daß die gesamten Aufbauvitrinen, obwohl sie nur durch Zusammenstecken von Rahmen und Platten gebildet sind, durch Ergreifen der obersten Rahmen 3 wie festgefügte Nöbelstücke versetzt werden können. Die Platten werden durch die Klemmlippen fest in den Rahmen gehalten, obwohl sie sich beim Zusammenstecken der Vitrine relativ leicht in die Nuten 5 einschieben lassen.In an exemplary embodiment according to FIGS shown to 4 that the entire display cabinets, although only are formed by putting frames and plates together, by grasping the uppermost frame 3 like firmly attached pieces of furniture can be moved. The plates are made by the Clamping lips held firmly in the frame, even though they are in the Sliding the display case relatively easily into the grooves 5 let it slide in.

Die Figuren 5 bis 10 zeigen Varianten der Ausbildung der Klemmlippe 9, bei denen aber immer der widerhakenähnliche Effekt der Klimmlippen zur Verhinderung der Entnahme der Platten aus der Nut 5 auftritt.Figures 5 to 10 show variants of the design of the Clamping lip 9, but always with the barb-like one Effect of the chin lips to prevent the removal of the Plates from the groove 5 occurs.

Die Figuren 5 und 6 zeigen eine Ausführungsform, bei der die Klemmlippe 14 an ihrem freien Ende mit einer Hohlprofil 15 versehen ist. Die Wand 10 der Nut 5 ist hier mit einer kreisbogenförmigen Ausnehmung 16 so versehen, daß sich das hohlprofil 15 der Klemmlippe 14 beim Einschieben einer Platte 4 (Fig. 6) in die Ausnehmung 16 legt und daher selbst kaum verformt wird. Hier muß die Ausbildung der Klemmlippe 14 in ihrer Befestigungsbereich so gewählt werden, daß das elastische Zurseitedrücken der Klemmlippe 14 eine genügend große Rückstellkraft bewirkt, die ausreicht, um den vorher erwähnten Hafteffekt der Klemmlippe 14 an der Platte 4 zu bewirken und um die dadurch bedingte Widerhakenfunktion zu sichern.Figures 5 and 6 show an embodiment in which the Clamping lip 14 at its free end with a hollow profile 15 is provided. The wall 10 of the groove 5 is here with a provided an arcuate recess 16 so that the hollow profile 15 of the clamping lip 14 when inserting a plate 4 (Fig. 6) in the recess 16 and therefore hardly itself is deformed. Here the formation of the clamping lip 14 in their attachment area should be chosen so that the elastic Push the clamping lip 14 to a sufficiently large restoring force causes that is sufficient to the previously mentioned Adhesion effect of the clamping lip 14 on the plate 4 and around to secure the resulting barb function.

Die Figuren 7 und 8 zeigen eine ähnliche Ausführungsform, bei der die Klemmlippe 16 an ihrem freien Ende auch mit einem Hohlprofil 17 versehen ist. Hier ist im Gegensatz zur Ausführungsform der Figuren 5 und 6 die Anlenkstelle der Klemmlippe 16 an der Wand 10 aber dünner ausgebildet. Die Abmessungen des Hohlprofiles 17 und der Nut 5 sind aber so gewählt, daß sich das Hohlprofil 17 beim Einfuhren einer Platte 14 elastisch zu einem Oval verformt, wie das in Fig. 8 gezeigt ist. Dadurch entstehen zusätzliche elastische Rückstellkräfte, die wiederum ausreichend sein müssen, um aufgrund der gegebenen Reibungskoeffizienten die Klemmlippe 16 mit dem an der Platte anliegenden Teil an dieser zu halten, wenn eine Zugkraft auf die Platte ausgeübt wird. Auch dann wird die Klemmlippe 16 im Uhrzeigersinn bewegt und verklemmt sich dadurch immer mehr an der Platte 4.Figures 7 and 8 show a similar embodiment, at of the clamping lip 16 at its free end with one Hollow profile 17 is provided. Here is in contrast to the embodiment 5 and 6 the articulation point of the clamping lip 16 on the wall 10 but thinner. The dimensions of the hollow profile 17 and the groove 5 are so chosen that the hollow profile 17 when importing a plate 14 elastically deformed into an oval, as shown in FIG. 8 is. This creates additional elastic restoring forces, which in turn have to be sufficient to Friction coefficient the clamping lip 16 with that on the plate adjacent part to hold on to this when a pulling force is on the plate is exercised. Even then, the clamping lip 16 in Clockwise moves and jams more and more the plate 4.

Die Figuren 9 und 10 zeigen eine Ausführungsform, bei der zwei Klemmlippen 18 und 19, die im Querschnitt etwa Tropfenform aufweisen, dessen schmälere Seite an der Wandung 10 befestigt ist, mit dem Rahmen 3 verbunden sind. Die erste, obere Klemmlippe 18 ist einschließlich ihrer Befestigungsstelle in etwa identisch zu der zweiten Klemmlippe 19 ausgebildet. Bei der Herstellung ist lediglich das Weich-PVC der Klemmlippe 19 an der Grenzlinie zum Hart-PVC der Ward 10 etwas anders geneigt als bei der oberen Klemmlippe 18. Fig. 10 zeigt, daß beim Einschieben der Platte beide Klemmlippen zunächst im Gegenuhrzeigersinn nach unten zum Nutgrund 5a hin schwenken, bei einer Zugkraft auf die Platte 4 aber versuchen, sich im Uhrzeigersinn zu verschwenken und so den Klemmeffekt hervorrufen.Figures 9 and 10 show an embodiment in which two Clamping lips 18 and 19, which are approximately teardrop-shaped in cross section, the narrower side of which is attached to the wall 10, are connected to the frame 3. The first, upper clamping lip 18 is approximately identical, including its attachment point to the second clamping lip 19. In the preparation of is only the soft PVC of the clamping lip 19 on the Boundary line to the hard PVC of Ward 10 inclined slightly different than at the upper clamping lip 18. Fig. 10 shows that when inserting the plate, both clamping lips initially counterclockwise Swivel down to the groove base 5a with a pulling force on plate 4 but try to pivot clockwise and so cause the pinching effect.
