Sonnenschirme grosser Spannweite, wie sie z.B. für Restaurantgärten gebraucht werden, stellen in zusammengefaltetem Zustand ein zumindest entsprechend der Länge der Tragstäbe hohes säulenartiges Gebilde dar, das sich zudem durch die beim Aufspreizen sich nach aussen bewegenden Tragstäbe nur schwer öffnen lässt. In der Nähe stehende Tische oder Stühle müssen zuvor beiseite geräumt werden.Large-span parasols such as for restaurant gardens are needed, put in folded Condition at least according to the length of the support rods high columnar structure, which is also characterized by the when spreading outward-moving supporting rods only difficult to open. Nearby tables or chairs must first be cleared aside.

Der Erfindung liegt die Aufgabe zugrunde, einen Sonnenschirm der genannten Art zu finden, die eine Vergrösserung ihrer Abschirmfläche ermöglicht, die in zusammengefaltetem Zustand besonders kompakt ist und die sich leicht öffnen lässt, ohne dass dabei eine Behinderung durch umstehende Einrichtungen gegeben ist. Ausserdem soll eine Vorrichtung solcher Art gefunden werden, die aufgrund ihres grundsätzlichen Konstruktionsprinzips zahlreiche neue Ausführungsformen und Anwendungsmöglichkeiten eröffnet, die eine optimale, den örtlichen Gegebenheiten und der Sonnenstrahlung angepasste Verwendung ermöglichen.The invention has for its object a parasol of the type mentioned to find an enlargement of their Shielding surface allows that in the folded state is particularly compact and can be opened easily without that there is a disability due to surrounding facilities given is. In addition, a device of this type is to be found be due to their basic design principle numerous new embodiments and possible applications opened, the optimal, the local Conditions and use adapted to solar radiation enable.

Aufgrund der erfindungegemässen Merkmale ist es möglich, die Tragstäbe beim Zusammenlegen des Sonnenschirms auf angenähert die Hälfte ihrer Länge zu verkürzen, so dass ein kompaktes Gebilde entsteht. Bei aufgespannten können die übereinanderschiebbaren Flächengebilde mit verschiedenen Ueberdeckungspositionen zum Abschirmen gegen Sonneneinstrahlung benutzt werden, z.B. um die Sonneneinstrahlung durch begrenzt durchlässige Flächenelemente unterschiedlich abzufiltern, um Windkräfte zu reduzieren und/oder um bei Regen eine sichere Abschirmung zu erreichen. Zwischen sich überdeckenden Flächenelementen kann Luft zirkulieren, so dass die Wärmeentwicklung bei Sonneneinstrahlung unter der Vorrichtung weiter reduziert wird.Due to the features of the invention, it is possible to Support rods when folding the parasol shorten to approximately half their length so that a compact structure is created. With clamped can the superimposed fabrics with different coverage positions to shield against Solar radiation are used, e.g. to the sun exposure different due to limited permeable surface elements filter to reduce wind forces and / or to achieve safe shielding in the rain. Between overlapping surface elements can circulate air, so that the heat development when exposed to sunlight the device is further reduced.

Um das zusammenlegen des Sonnenschirms zu einer kompakten Einheit zu erleichtern, bestehen die Flächenelemente vorzugsweise aus plissiertem Flächenmaterial, so dass die Plissierfalten von übereinander angeordneten Flächenelementen beim Zusammenlegen ineinandergreifen.To fold the parasol into a compact one To facilitate unity, the surface elements preferably consist from pleated surface material, so that the Pleats of surface elements arranged one above the other interlock when folding.

Eine besonders ästhetische, geschlossene Form erhält die kompakte Einheit des Sonnenschirms in bevorzugter Ausführungsform der Erfindung durch Hüllflächen, die an den in dieser Position äusseren Stabelementen vorgesehen sind.The is given a particularly aesthetic, closed form compact unit of the parasol in a preferred embodiment of the invention by enveloping surfaces on the in this Position outer rod elements are provided.

Die kompakte, geschlossene Form des Sonnenschirms kann weiter verbessert werden, wenn bei ihrer AUsführung als Gartenschirm der Mast so weit verkürzbar ist, bis die Enden der parallel zum Mast zusammengelegten Tragstäbe mindestens angenähert an den Boden oder einen Sockel des Sonnenschirms heranreichen.The compact, closed shape of the parasol can go further can be improved if they are designed as a garden umbrella the mast can be shortened until the ends of the At least support rods folded parallel to the mast approximated to the floor or a base of the parasol reach up.

Die Tragstäbe 1, von denen beispielsweise acht vorhanden sind, erstrecken sich bei aufgespreizter Vorrichtung von einem zentralen Kopfteil 2 aus, z.B. leicht geneigt, radial nach aussen und sind mit diesem durch ein einachsiges Gelenk verbunden, so dass sie zu einer kompakten Einheit, z.B. entsprechend Fig. 18,19,21, mindestens angenähert parallel zueinander nach unten schwenkbar sind.The support rods 1, of which eight are present, for example are, with the device spread out from a central head part 2, e.g. slightly inclined, radial to the outside and are with this through a uniaxial Joint connected so that it becomes a compact unit, e.g. corresponding to Fig. 18,19,21, at least approximately parallel are pivotable towards each other downwards.

Die acht Tragstäbe 1 des Ausführungsbeispieles nach Fig. 1,2 oder nach Fig.26 und 28 haben jeweils ein im aufgespreizten Zustand der Sonnenschirms radial inneres und äusseres Stabelement 4,5, die verschiebbar aneinander geführt sind, indem sie entsprechend der Schnittdarstellung in Fig.3 oder in Fig.36 aus ineinandergreifenden Profilstäben bestehen. Der gegenseitige Eingriff erfolgt beispielsweise in Form eines T-Querschnittes, mit einem umfassenden T-förmigen Hohlquerschnitt und einem T-förmigen Eingriffsteil 6,6'. Ausserdem hat der Querschnitt der Stabelemente 4,5 zur Bildung längsverlaufender Aufnahmekanäle 7 bis 12 beidseitig nach aussen offene, z.B. c-förmige Querschnittsbereiche.The eight support rods 1 of the embodiment shown in FIG. 1,2 or according to Fig. 26 and 28 each have a spread Condition of the parasol radially inner and outer rod element 4,5, which are slidably guided together by they according to the sectional view in Figure 3 or in Fig. 36 consist of interlocking profile bars. The mutual engagement takes place, for example, in the form of a T-section, with a comprehensive T-shaped hollow section and a T-shaped engagement part 6,6 '. Furthermore has the cross section of the rod elements 4.5 to form longitudinal Receiving channels 7 to 12 on both sides to the outside open, e.g. C-shaped cross-sectional areas.

Das oberste oder äussere Paar 7,8 der Aufnahmekanäle des inneren Stabelementes 4 dient der Aufnahme des wulstförmigen Randes 13 (Fig.15) von steifen Schalenelementen 14,15, z.B. aus Aluminium, die gemeinsam mit den anderen, jeweils zwischen zwei Tragstäben 1 gehaltenen Schalenelementen 14,15 eine geschlossene Hülle bilden, die den Schirm in geschlossenem Zustand entsprechend den Darstellungen der Fig.18 und 19 verkleidet und die nach Oeffnen des Schirmes mit Abstand voneinander auf diesem aufliegen. Dies zeigt die Aufsicht auf eine Vorrichtung nach Fig.16 und insbesondere die zugehörige Querschnittsdarstellung der Fig.17. Anstatt in Aufnahmekanälen leicht schwenkbar gelagert zu sein, können Schalenelemente auch flügelartig beidseitig an dem jeweiligen Stabelement 4 starr angeformt sein, wie es die Querschnittsdarstellung nach Fig. 30 zeigt.The top or outer pair 7,8 of the receiving channels of the inner Bar element 4 serves to accommodate the bead-shaped Edge 13 (Fig. 15) of rigid shell elements 14, 15, e.g. made of aluminum, which, together with the others, each between two supporting rods 1 held shell elements 14, 15 form a closed envelope, which the screen in closed State according to the representations of Fig. 18 and 19 disguised and after opening the screen with a distance of each other lie on this. This shows the supervision on a device according to Fig.16 and in particular the associated Cross-sectional view of Fig.17. Instead of in recording channels can be easily pivoted Shell elements also wing-like on both sides of the respective Rod element 4 can be rigidly formed, as is the cross-sectional representation 30 shows.

Die übrigen Aufnahmekanäle 9 bis 12 des Ausführungsbeispieles nach Fig.15 dienen der Aufnahme und Halterung eines Randes 16 einzelner, dreieck- oder trapezförmiger flexibler Flächenelemente 17,18, z.B. nach Art eines Kedereingriffs, wie es für die Befestigung der Ränder von Markisenflächen üblich ist.The remaining receiving channels 9 to 12 of the embodiment according to Fig. 15 are used to hold and hold an edge 16 individual, triangular or trapezoidal flexible Surface elements 17, 18, e.g. in the manner of a piping intervention, like it is for fixing the edges of awning surfaces is common.

Da sich die Ränder der Flächenelemente 17,18 jeweils über die Länge der Stabelemente 4,5 erstrecken, überlappen sich bei voll aufgespreiztem Schirm (Fig.5) die inneren und äusseren Flächenelemente 17,18 innerhalb eines verbleibenden Eingriffsbereiches 20 zwischen den Stabelementen 4,5. Da das radial innere Flächenelemente 17 im Bereich der Ueberlappung mit einem Abstand über dem radial äusseren Flächenelement 18 angeordnet ist, der dem durch die Dimension und Gestaltung des Querschnittes der nebeneinander und aneinander geführten Stabelemente 4,5 betimmten Abstand zwischen den Aufnahmekanälen 9 und 11 bzw. 10 und 12 entspricht, hat die Vorrichtung eine diesem Abstand entsprechende, umlaufende Spaltöffnung, durch die ein Luftaustausch erfolgen kann, so dass der Raum unterhalb der Abschirmfläche des Sonnenschirms belüftet oder entlüftet wird.Since the edges of the surface elements 17, 18 each overlap extend the length of the rod elements 4.5, overlap with the screen fully open (Fig. 5) the inner and outer Area elements 17, 18 within a remaining one Engagement area 20 between the rod elements 4.5. Since that radially inner surface elements 17 in the area of the overlap at a distance above the radially outer surface element 18 is arranged by the dimension and design of the cross section of the side by side and led together Rod elements 4.5 determined distance between the receiving channels 9 and 11 or 10 and 12 corresponds to the device a circumferential gap opening corresponding to this distance, through which an air exchange can take place, so that the Ventilated space below the shielding surface of the parasol or is vented.

Die Stützstäbe 21 sind gelenkig mit den radial nach aussen schiebbaren Stabelementen 5 verbunden, so dass sich bei zu maximaler Grösse aufgespanntem Sonnenschirm durch die weit nach aussen ragenden Stützstäbe 21 eine stabile Abstützung ergibt. Damit die Stützstäbe 21 und entsprechend der Mast 3 nicht entsprechend lang ausgeführt werden müssen und sich auch zu Beginn der Aufspreizung statisch günstige Winkelpositionen der Stützstäbe 21 ergeben, bestehen diese beispielsweise aus zwei über ein Gelenk 22 miteinander verbundenen Stützstabelementen 23,24. Die an dem unteren Schiebekörper 25 angelenkten inneren Stützstabelemente 23 sind jeweils durch einen zwischen seinen Enden angreifenden Hilfsstützstab 26 zusätzlich gehalten, indem dieser an einem zweiten, auf dem Mast 3 geführten oberen Schiebekörper 27 angelenkt ist. The support rods 21 are articulated with the radially outward sliding rod elements 5 connected, so that when maximum size stretched parasol through the far a stable support projecting outwards results. So that the support rods 21 and accordingly the mast 3rd do not have to be carried out accordingly long and yourself Statically favorable angular positions also at the beginning of the spreading of the support rods 21, these are, for example of two connected to each other via a joint 22 Support rod elements 23.24. The on the lower sliding body 25 articulated inner support rod elements 23 are each by an auxiliary support rod engaging between its ends 26 additionally held by this on a second upper sliding body 27 guided on the mast 3 is articulated.

Fig.2 veranschaulicht eine Position der Stützstabelemente 23,24, wenn sich der Schirm in einer kleineren Spreizposition (Fig.6) befindet, in der der Schirm beispielsweise einen Durchmesser von 3 m hat. Bei weiterem Aufwärtsschieben des unteren Schiebekörpers 25 wird der obere Schiebekörper 27 an einem Anschlag 28 gestoppt, so dass das innere Stützstabelement 23 weiter nach aussen schwenkt und zu dem verschiebbaren Stabelement 5 eine Winkelposition einnimmt, bei der dieses nach aussen geschoben wird, so dass sich die Abschirmfläche der Vorrichtung entsprechend kontinuierlich vergrössern lässt. Eine gleichartige Kinematik ist auch bei dem Ausführungsbeispiel der Fig. 28 vorhanden.Fig. 2 illustrates a position of the support bar elements 23.24 when the umbrella is in a smaller spread position (Fig.6), in which the screen, for example, a Has a diameter of 3 m. When pushing further up of the lower sliding body 25 becomes the upper sliding body 27 stopped at a stop 28, so that the inner support rod element 23 pivots further out and towards the movable Rod element 5 assumes an angular position which is pushed outwards so that the Shielding surface of the device accordingly continuously lets enlarge. A similar kinematics is also with 28 of the embodiment of FIG.

Das Ausführungsbeispiel nach Fig.10 und 11 unterscheidet sich vom zuvor beschriebenen im wesentlichen durch eine dreiteilige Ausführung der Tragstäbe 1', indem zwischen dem unteren, mit dem Stützstab 21' verbundenen Stabelement 5' und dem oberen, an dem Kopfteil 2' angelenkten Stabelement 4' ein drittes Stabelement 30 sich mit diesen in Schiebeeingriff befindet. Die Querschnittsdarstellung nach Fig.11 zeigt, dass dieser Schiebeeingriff nach dem Prinzip des Ausführungsbeispieles der Fig.3 gestaltet sein kann. Die somit zwischen jeweils zwei Stabelementen 4' und 5' geführten mittleren Stabelemente 30 lassen sich zusammen mit den an ihnen befestigten Flächenelementen 31 von der in Fig.10 gezeigten inneren Position nach aussen verschieben. Ihre Flächenelemente 31 werden somit in der gezeigten inneren Position von denjenigen der inneren Stabelemente 4' überdeckt, und in ausgezogener Position überdecken die Flächenelemente 31 diejenigen der Stabelemente 5'. Zwischen beiden Positionen sind stufenlos Zwischenpositionen einstellbar. Die verschiedenen überdeckenden Positionen, die auch für in Umfangsrichtung der Vorrichtung benachbarte Flächenelemente unterschiedlich ausgeführt werden können, ermöglichen somit eine den örtlichen Gegebenheiten oder dem Sonnenstand angepasste verbesserte Abschirmung gegenüber Sonneneinstrahlung. Die Luftschicht zwischen den übereinander liegenden Flächenelementen 17,31 bzw. 18,31 trägt zur guten Wärmeisolation bei.The embodiment of Figures 10 and 11 differs differs from the previously described essentially by a three-part design of the support rods 1 'by between lower rod element 5 'connected to the support rod 21' and the upper rod element articulated on the head part 2 ' 4 ', a third rod element 30 engages with it in sliding engagement located. The cross-sectional view according to Fig.11 shows that this sliding intervention according to the principle of the embodiment 3 can be designed. The thus guided between two rod elements 4 'and 5' middle bar elements 30 can be together with the attached surface elements 31 of that shown in Fig.10 move the inner position outwards. Your surface elements 31 are thus in the inner position shown covered by those of the inner rod elements 4 ', and in the extended position cover the surface elements 31 those of the bar elements 5 '. Between the two positions intermediate positions are infinitely adjustable. The different overlapping positions, also for circumferentially surface elements adjacent to the device can thus be carried out differently one adapted to the local conditions or the position of the sun improved shielding from solar radiation. The air layer between the superimposed surface elements 17.31 and 18.31 contributes to good thermal insulation at.

Vorzugsweise sind die zwischen den Stabelementen 4' und 5' geführten mittleren Stabelemente 30 mit den Stabelementen 5' lösbar verriegelt, mit denen die Stützstäbe 21' verbunden sind. Folglich können diese Stabelemente 30 wahlweise mit den an ihnen befestigten Flächenelementen beim vollständigen Oeffnen der Vorrichtung gemeinsam mit den Stabelementen 5' durch die Stützstäbe 21' nach aussen geschoben werden, z.B. um auch im äusseren Umfangsbereich des Sonnenschirms eine regendichte Abschirmung zu erreichen. Falls jedoch die Ueberdeckung der den Stabelementen 5' und 30 zugeordneten Flächenelemente im äusseren Umfangsbereich des Sonnenschirms vermieden werden soll, so ist die Verriegelung zwischen den Stabelementen 5' und 30 bei unvollständig geöffneter Vorrichtung zu lösen. Sie kann stattdessen zwischen den Stabelementen 4' und 30 hergestellt werden. Die Verriegelung kann auf einfachste Weise mittels einer Andruckschraube erfolgen oder z.B. durch Klemmhebel, wie sie beispielsweise für die gegenseitige Verriegelung der Beinelemente von Stativen üblich sind.Preferably between the bar elements 4 'and 5' guided middle bar elements 30 with the bar elements 5 ' releasably locked, with which the support rods 21 'connected are. Consequently, these rod elements 30 can optionally with the surface elements attached to them when complete Opening the device together with the rod elements 5 ' are pushed outwards by the support rods 21 ', e.g. to ensure that it is rainproof even in the outer circumferential area of the parasol To achieve shielding. However, if the overlap of the surface elements assigned to the rod elements 5 'and 30 avoided in the outer circumferential area of the parasol is to be the interlock between the Bar elements 5 'and 30 when the device is incompletely open to solve. Instead, it can be placed between the bar elements 4 'and 30 are produced. The lock can be done in the simplest way using a pressure screw or e.g. by clamping levers, such as those for the mutual locking of the leg elements of tripods are common.

Die mögliche gegenseitige Ueberdeckung der Flächenelemente ermöglicht auch vorteilhaft die wahlweise Verwendung von Sonnenstrahlen begrenzt filternden Textil- oder Folienmaterialien, um eine schonendere Hautbräunung zuzulassen. Für eine stärkere Abschirmung werden dann durch teilweises Zusammenschieben des Schirms diese durchlässigeren Flächenelemente 17,18 durch ein anderes Flächenelement 31 von oben oder unten überdeckt.The possible mutual overlap of the surface elements also advantageously allows the optional use of Filtering textile or foil materials, to allow a more gentle skin tanning. For a stronger shielding is then achieved by partially pushing them together of the screen these more permeable surface elements 17, 18 by another surface element 31 from above or covered below.

Um ein Durchhängen der Flächenelemente 17,18,31 bei unvollständiger Spreizung des Schirmes zu vermeiden und um ein leichtes Schliessen des Schirmes in eine kompakte Form zu ermöglichen, bestehen diese vorzugsweise aus plissiertem Markisenstoff oder aus einem vergleichbaren Material, das in entspanntem Zustand bei zusammengelegtem Sonnenschirm entsprechend den Querschnittsdarstellungen der Fig.4 und 33 eine spitze, zickzackförmige Querschnittsform einnimmt. Ausserdem erstrecken sich mit Federzügen 33,34 verbundene Spannschnüre 35, 36 zwischen den Tragstäben 1' in Umfangsrichtung des Sonnenschirms. Diese Federzüge verlaufen beispielsweise entlang der Tragstäbe 1', und somit längs der Seitenkanten der Flächenelemente 17,18,31, so dass in den Eckbereichen Umlenkstellen 38 vorzusehen sind. Die Verbindung mit den Flächenelementen 17,18,31 erfolgt durch Hindurchführung der Spannschnüre 35,36 durch Löcher oder Schlitze in deren Faltungsbereichen 39.For sagging of the surface elements 17, 18, 31 in the case of incomplete Avoid spreading the screen and around one easy closing of the screen in a compact form enable, these are preferably made of pleated Awning fabric or a comparable material that in relaxed state when the parasol is folded the cross-sectional representations of Figures 4 and 33 assumes a pointed, zigzag cross-sectional shape. In addition, 33.34 connected with spring balancers Tension cords 35, 36 between the support rods 1 'in the circumferential direction of the parasol. These balances run, for example along the support rods 1 ', and thus along the Side edges of the surface elements 17, 18, 31, so that in the Corner areas deflection points 38 are to be provided. The connection with the surface elements 17, 18, 31 is carried out of the tension cords 35, 36 through holes or Slits in their folding areas 39.

Die Aufteilung des der Abschirmung gegen Sonne, Wind, Regen oder unerwünschte Einblicke dienenden Flächengebildes in einzelne austauschbare Flächenelemente ermöglicht die beschriebene, vergrösserbare und/oder mehrschichtige Gestaltung eines Sonnenschirms. Sie ermöglicht aber auch auf einfache Weise die Realisierung von besonderen Formen des Flächengebildes, wie es die Ausführungsbeispiele der Fig.7 bis 9 zeigen. Die Ausführungsformen der Fig.7 bis 9 lassen sich ohne wesentliche Aenderungen am Traggestänge des Schirmes verwirklichen, indem in mindestens einem bestimmten Umfangsbereich des Schirmes lediglich äussere Flächenelemente 40,41;40', 41'; 40'',41'' zwischen äusseren Stabelementen 5 eine andere Zuschnittform aufweisen und ein äusseres Stabelement 5 jeweils verkürzt oder verlängert wird. The division of the shield against sun, wind, rain or unwanted insight serving fabric in The described, enlargeable and / or multilayer design of an umbrella. But it also enables simple way of realizing special forms of Flat structure, as is the embodiment of Fig.7 show to 9. The embodiments of Fig.7 up to 9 can be made on the supporting linkage without significant changes of the screen by at least one certain peripheral area of the screen only outer Surface elements 40, 41; 40 ', 41'; 40 '', 41 '' between outer Rod elements 5 have a different cut shape and a Outer rod element 5 shortened or lengthened becomes.

Fig.26 und 27 zeigen eine Austührungsform des Sonnenschirms bei dem im Gegensatz zu denjenigen der Fig.1,2 und 10 die Stützstäbe 50 einteilig sind. Um dennoch die Abstützstelle an dem Gelenk 51 beim zunehmenden Aufspreizen entlang dem jeweiligen Tragstab 1 nach aussen zu bewegen, ist das Gelenk 51 für den Stützstab 50 entweder entsprechend Fig.26 an dem nach aussen verschiebbaren Stabelement 5 vorgesehen oder entsprechend Fig.27 an einem relativ kurzen Gleitelement 53, das an dem Tragstab 1 bzw. an einem Stabelement 4 oder 5 geführt ist. Beim Aufwärtsschieben des unteren Schiebekörpers 25 werden die Tragstäbe 1 durch die Stützstäbe 50 zuerst nach oben geschwenkt. Anschliessend wird der obere Schiebekörper 27 an einem an dem Mast 3 befestigten Anschlag 54 gestoppt. Bei weiterer Aufwärtsbewegung des unteren Schiebekörpers 25 schwenken die Stützstäbe 50 nach Art eines Scherenschenkels nach aussen, so dass die Gleitelelemente 53 oder die Stabelemente 5 mit den zugehörigen Flächenelementen 18 entsprechend kontinuierlich nach aussen geschoben werden. Die somit nach aussen verlagerte Abstützung trägt wesentlich zur Stabilität des Sonnenschirms bei. Fig.28 zeigt eine Ausführungsform mit dem kinematischen System nach Fig.1,2, wobei durch Strich- und Strich-Punktlinien zwei weitere Spreizpositionen der Stützstabelemente 23,24 dargestellt sind. Wie auch bei den Ausführungsbeispieien der Fig.26 und 27 wird die Rückwärtsbewegung des Stabelementes 5 und damit auch die dem Spreizen entgegengesetzte Rückwärtsbewegung der Stützstabelemente 23,24 durch eine Zugfeder 52 erleichtert, die zwischen den kopfseitigen Enden der Stabelemente 4,5 befestigt ist.Fig. 26 and 27 show an embodiment of the parasol in which, in contrast to those of FIGS. 1, 2 and 10, the Support rods 50 are in one piece. To the support point anyway on the joint 51 as it spreads along the To move the respective support rod 1 outwards is the joint 51 for the support rod 50 either according to Fig.26 on the provided to the outside displaceable rod element 5 or 27 on a relatively short sliding element 53, performed on the support rod 1 or on a rod element 4 or 5 is. When pushing the lower slide body upwards 25, the support rods 1 through the support rods 50 first pivoted upwards. Then the upper sliding body 27 stopped at a stop 54 attached to the mast 3. With further upward movement of the lower sliding body 25 pivot the support rods 50 in the manner of a scissor leg outwards so that the sliding elements 53 or the rod elements 5 with the associated surface elements 18 are correspondingly continuously pushed outwards. The support thus shifted to the outside is essential to the stability of the parasol. Fig. 28 shows an embodiment with the kinematic system according to Fig. 1,2, whereby two more by dash and dash-dotted lines Spread positions of the support rod elements 23,24 shown are. As with the exemplary embodiments in FIGS. 26 and 27 is the backward movement of the rod element 5 and thus also the backward movement of the Support rod elements 23, 24 relieved by a tension spring 52, attached between the head ends of the rod elements 4.5 is.

Für die Aufwärtsbewegung des unteren Schlebekörpers 25 ist vorzugsweise ein Drehantrieb 55 vorhanden, der einen nichtdargestellten Elektromotor oder eine langgestreckte Handkurbel 56 aufweist. Der Drehantrieb 55 hat eine Gewindeschnecke 57, die in ein Schneckenrad 58 eingreift. Letzteres treibt entweder die Rolle eines im oberen Bereich des Mastes 3 befestigten seilzuges 59 an oder ein Zahnrad, das mit einer sich längs des Mastes 3 erstreckenden Zahnstange in Eingriff steht.For the upward movement of the lower body 25 is preferably a rotary drive 55 is present, which is not shown Electric motor or an elongated hand crank 56 has. The rotary drive 55 has a screw 57, which engages in a worm wheel 58. The latter drives either the role of an attached in the upper part of the mast 3 cable 59 or a gear that with a gear rack extending along the mast 3 stands.

Um im vollständig zusammengelegten Zustand des Gartenschirmes, d.h. bei nach unten gerichteten, durch Zusammenschieben verkürzten Tragstäben 1 ein besonders kompaktes Gebilde entsprechend der ersten Position der Darstellungen in Fig.21 zu erhalten, ist weiterhin der Mast teleskopartig verlängerbar, so dass er sich vor dem Aufspreizen mit dem Ende 61 der zusammengeschobenen Tragstäbe 1 über Tischhöhe hinaus nach oben bewegen lässt. Auch für diese Aufwärtsbewegung ist vorzugsweise ein Drehantrieb 62 vorgesehen, z.B. mit einer Antriebsschnecke 63 und einem Schneckenrad 64. Letzteres treibt eine Hubspindel 65 an, die mit einer Spindelmutter 66 in Eingriff steht, so dass diese zusammen mit dem an ihr befestigten, den oberen Mastteil 67 tragenden Schaft 68 auf- und abwärts bewegbar ist. Somit lässt sich die Vorrichtung leicht aufspreizen, obwohl die sich dabei erheblich nach aussen bewegenden Tragstäbe 1 einen Aufenthalt in der Nähe des Mastes 3 verhindern würden.In the fully folded state of the garden umbrella, i.e. with downwards, by pushing together shortened support rods 1 a particularly compact structure corresponding to the first position of the representations in Fig. 21 the mast can be extended telescopically, so that it spreads out with the end 61 of the collapsed support rods 1 beyond table height can move up. Also preferred for this upward movement a rotary drive 62 is provided, e.g. with a drive screw 63 and a worm wheel 64. The latter drives a lifting spindle 65, which has a spindle nut 66 is engaged so that this together with the attached to it the upper mast part 67 carrying shaft 68 up and is movable downwards. The device can thus be slightly spread out, although the outside moving support rods 1 a stay nearby of the mast 3 would prevent.

Ein Gartenschirm mit einer minimalen Spannweite von z.B. 4 m entsprechend Fig.22 und mit einer maximalen Spannweite von z.B. 8 m entsprechend Fig.23 lässt sich somit bei Nichtgebrauch auf ein säulenartiges, kompaktes Gebilde nach Art der ersten Position der Fig.21 verkleinern, dessen Höhe nur ca. 2 m beträgt. Ein solches, relativ kurzes säulenartiges Gebilde, das durch die äusseren, die Flächenelemente 17,18 einschliessenden Hüllklappen 14,15 eine geschlossene, ästhetisch ansprechende Form hat,, passt sich gut in eine Gartenanlage o.dgl.ein, während ein zusammengeklappter Gartenschirm vorbekannter Bauart mit vergleichbarer Spannweite bereits aufgrund seiner Höhe von 4 m, zuzüglich seiner freien unteren Mastlänge, hierfür meist nicht akzeptiert werden kann.A garden umbrella with a minimum span of e.g. 4 m corresponding to Fig. 22 and with a maximum span of e.g. 8 m according to Fig. 23 can thus be used when not in use to a columnar, compact structure of the type of reduce the first position of Fig. 21, the height of which is only approx. Is 2 m. Such a relatively short columnar structure, by the outer, the surface elements 17, 18 enclosing flaps 14, 15 a closed, aesthetic has an attractive shape, fits well in a garden or the like, while a folded garden umbrella already known design with a comparable span already due to its height of 4 m, plus its free lower mast length, mostly not accepted for this can.

Die Querschnittsdarstellung der Fig.11 und 29 veranschaulichen, dass aufgrund der übereinanderliegenden Anordnung der Stabelemente 4,5 die in Umfangsrichtung der Vorrichtung benachbarten, dreieck- und trapezförmigen Flächenelemente 17,18 nicht wie bei üblichen Regenschirmen zu einem einheitlichen Flächengebilde miteinander vernäht sein können, sondern dass ihre einzelne, seitliche Befestigung an den Stabelementen 4,5 erforderlich ist. Hierzu eignet sich eine Befestigung nach dem in Fig.15 dargestellten Kederprinzip. Dieses hat jedoch den Nachteil, dass der Rand 16 der Flächenelemente 17,18 in seiner Längsrichtung in die Aufnahmerille 9,10 eingezogen werden muss, so dass er über seine Länge nicht gegen Verschieben gesichert ist und folglich ein Verziehen der Flächenelemente nur im Bereich seiner befestigten Enden verhindern kann. Ausserdem hat ein eingenähter Keder den Nachteil, dass sich an den Nähten Kraftkonzentrationen ergeben, die bei Dauerbeanspruchung zum Lösen der Naht oder Beschädigungen am Flächenelement 17,18 führen können.11 and 29 illustrate that because of the stacked arrangement the rod elements 4, 5 in the circumferential direction of the device neighboring, triangular and trapezoidal surface elements 17.18 not like a common umbrella Fabric can be sewn together, but that their individual, lateral attachment to the bar elements 4.5 is required. A is suitable for this Fastening according to the piping principle shown in Fig. 15. However, this has the disadvantage that the edge 16 of the surface elements 17.18 in its longitudinal direction in the receiving groove 9.10 must be confiscated so that it passes over its Length is not secured against shifting and consequently one Warp of the surface elements only in the area of its fastened Can prevent ends. Also has a sewn in Keder the disadvantage that there are concentrations of force at the seams result in the permanent stress to solve the Seam or damage to the surface element 17, 18 can result.

In bevorzugter Ausführungsform der Erfindung wird vorgeschlagen, entsprechend dem Ausführungsbeispiel nach Fig.29 bis 34, den durch z.B. lose Faltung oder loses Einrollen zumindest doppelt gelegten Rand 70 der Flächenelemente 17,18 durch mindestens ein leistenförmiges Blockierelement 71 in einem Kanal 72 des Stabelementes (4,5) zu halten. In diesem Aufnahmekanal 72 ist in der Position, die das Blockierelement 71 einnimmt oder aufgrund der Querschnittsform des Blockierelementes 71 zwischen diesem und einer Kanalwand 73 ein keilspaltförmiger Raum 74 vorhanden, der den zumindest doppelt gelegten Rand des Flächenelementes 17,18 einschliesst.In a preferred embodiment of the invention, it is proposed that corresponding to the embodiment according to Fig. 29 to 34, which by e.g. loose folding or rolling at least double edge 70 of the surface elements 17, 18 by at least one strip-shaped blocking element 71 in to hold a channel 72 of the rod element (4,5). In this Receiving channel 72 is in the position that the blocking element 71 occupies or due to the cross-sectional shape of the Blocking element 71 between this and a channel wall 73 a wedge-shaped space 74 is present, which at least double edge of the surface element 17,18 includes.

Vorzugsweise hat der durch Hinterschneidungen 75,76 an seinen beiden Querschnittsenden begrenzte Aufnahmekanal 72 eine grösste Breite, die ausreichend grösser ist als die Breite des leistenförmigen Blockierelementes 71, um in verkanteter Position ein Einsetzen des Blockierelementes 71 in den Kanal quer zu dessen Längsrichtung zu ermöglichen. Somit ist diese Breite mindestens um das Mass einer der Hinterschneidungen 76 zuzüglich der Dicke des Flächenelementes 17,18 grösser als die grösste Breite des Blockierelementes 71, wie es der Darstellung der Fig.31 entnommen werden kann. Dieses Uebermass der Breite des Aufnahmekanals 72 gegenüber der Breite des Blockierelementes 71 kann jedoch auch kleiner sein. In diesem Fall ist das Blockierelement 71 vom Kanalende her einzuschieben. Ein dennoch vorhandenes deutliches Uebermass ermöglicht ein leichtes Einschieben, ohne dass der beispielsweise zuvor eingelegte Rand 70 des Flächenelementes in seiner Längsrichtung verschoben werden känn.Preferably, the undercut has 75,76 on its receiving channel 72 limited at both ends of the cross section greatest width, which is sufficiently larger than the width of the strip-shaped blocking element 71 in order to be tilted Position an insertion of the blocking element 71 in the channel to enable transverse to its longitudinal direction. So this is Width at least by the measure of one of the undercuts 76 plus the thickness of the surface element 17.18 larger than the largest width of the blocking element 71, as the Illustration of Fig. 31 can be seen. This excess the width of the receiving channel 72 compared to the width of the blocking element 71 can, however, also be smaller. In in this case the blocking element 71 is from the channel end to insert. An existing clear excess enables easy insertion without the need for example previously inserted edge 70 of the surface element in its longitudinal direction can be shifted.

Ein Eindrücken des leistenförmigen Blockierelementes 71 quer zur Längsrichtung des Kanals 72 kann jedoch auch ermöglicht werden, indem sein Querschnitt federnd verformbar ist. Die federnde Verformbarkeit des Querschnittes kann durch mindestens eine Querschnittskrümmung 78 gegeben sein. Beim dargestellten Ausführungsbeispiel sind zwei entgegengesetzt gerichtete Krümmungen 78,79 mit verschiedenem Radius an den Querschnittsenden vorgesehen. Das Flächenelement 17,18 ist über die den grösseren Radius aufweisende obere Krümmung 78 geführt, während die untere, entgegengesetzt gerichtete Krümmung 79 der Abstützung dient, sowie der Aufnahme des z.B. zwei Faltungen 80,81 aufweisenden Randes 70. Die entgegengesetzt gerichteten Krümmungen 78,79 des Querschnittes des Blockierelementes bewirken den schräg nach oben und zu dem Stabelement 4,5 hingerichteten Verlauf des mittleren Querschnittsteils 83, so dass mit der Kanalwand 73 der keilspaltförmige Raum 74 gebildet ist.A pushing in of the strip-shaped blocking element 71 transversely to the longitudinal direction of the channel 72 can, however, also be made possible by resiliently deforming its cross section. The resilient deformability of the cross section can by at least there is a cross-sectional curvature 78. In the illustrated Embodiment are two opposite directed curvatures 78.79 with different radius at the Cross-sectional ends provided. The surface element is 17, 18 over the larger curvature 78 led, while the lower, oppositely directed Curvature 79 is used for support, and the inclusion of e.g. two folds 80, 81 having edge 70. The opposite directed curvatures 78.79 of the cross section of the blocking element cause the diagonally upwards and towards the 4.5 element executed course of the middle Cross-sectional part 83, so that with the channel wall 73 the wedge-shaped Room 74 is formed.

Die Zugspannung an dem Flächenelement 17, 18 infolge der Aufspreizung der Vorrichtung, die bestrebt ist, dieses aus dem keilspaltförmigen Raum 74 herauszuziehen, führt einerseits zur Festklemmung des mindestens doppelt gelegten Randes 70 im keilspaltförmigen Raum 74 und ausserdem zur Festklemmung zwischen dem eine Hinterschneidung bildenden Profilschenkel 84 und an der oberen Krümmung 78 des Blockierelementes 71. Diese nur klemmende Halterung des Randes 70 der Flächenelemente 17,18 führt zu einer geringeren Beanspruchung ihres Materials und somit zu einer grösseren Dauerhaftigkeit der Vorrichtung. Neben der leichten Herstellbarkeit und Montage dieser Verbindung zwischen einem Flächenelement 17,18 und einem Stabelement 4,5 oder einer Tragstange 1 ermöglicht sie auch ein leichtes Auswechseln einzelner Flächenelemente 17, 18, um besondere Abschirmungseffekte der bereits erwähnten Art oder um neue ästhetische Effekte zu erzielen.The tensile stress on the surface element 17, 18 due to the spreading of the device that seeks to do this from the Pulling out wedge-shaped space 74 leads on the one hand for clamping the at least double edge 70 in the wedge-shaped space 74 and also for clamping between the profile leg forming an undercut 84 and on the upper curvature 78 of the blocking element 71. This only clamping bracket of the edge 70 of the surface elements 17.18 leads to less stress on her Material and thus to a greater durability of the Contraption. In addition to the ease of manufacture and assembly this connection between a surface element 17, 18 and a bar element 4,5 or a support rod 1 enables them also easy replacement of individual surface elements 17, 18 to special shielding effects of the aforementioned Art or to achieve new aesthetic effects.

Für eine möglichst zentrale Lagerung der Tragstäbe 1 oder der Stabelemente 4 an einem Kopfteil 2 der Vorrichtung, durch die ihr Auswärtsschwenken kinematisch erleichtert wird, haben diese ein Kopfende 86, das schräg oder rechtwinklig zu dem jeweiligen Lager 87 hin nach innen gerichtet ist. Auf diese Weise ergibt sich die in Fig.24 gezeigte seitliche Versetzung der Achsen der Lager 51 und 87, die ein Auswärtsschwenken der Tragstäbe 1 oder von Stabelementen 4 durch den Antrieb 55 ermöglicht.For a central storage of the support rods 1 or the rod elements 4 on a head part 2 of the device, by kinematically facilitating your swinging away , they have a head end 86 that is slanted or rectangular directed inward toward the respective bearing 87 is. This results in the one shown in Fig. 24 lateral displacement of the axes of bearings 51 and 87, the one Swiveling the support rods 1 or rod elements 4 outwards made possible by the drive 55.

Fig.35 zeigt eine weitere Ausgestaltung der Ausführungsform nach Fig.32, indem die Stützstäbe 50' ebenfalls über ein Gelenk 51 mit einem nach aussen verschiebbaren Stabelement 5'' der Tragstäbe 1 verbunden sind. Um jedoch die Stabelemente 5'' weiter zur Vergrösserung des Schirmes nach aussen schieben zu können, als es allein durch Ausschwenken der Stützstäbe 50' möglich ist, sind in vorteilhafter Ausgestaltung der Erfindung die Stützstäbe 50' durch die Spreizbewegung des Schirmes teleskopartig verlängerbar.Fig. 35 shows a further embodiment of the embodiment 32 by the support rods 50 'also via a joint 51 with an outwardly displaceable rod element 5 '' the support rods 1 are connected. However, around the bar elements Slide 5 '' further out to enlarge the screen to be able to do it just by swinging out the support rods 50 'is possible, are in an advantageous embodiment the invention the support rods 50 'by the spreading movement the screen can be extended telescopically.

Als Antrieb für diese teleskopartige Stützstabverlängerung dient die scherenartige Aufspreizbewegung die zwischen dem Hilfsstab 26 und dem Stützstab 50' während der Aufwärtsbewegung des unteren Schiebekörpers 25 und bei Anlage des oberen Schiebekörpers 27 an dem Anschlag 54 erfolgt. Hierfür ist ein Drahtseil 90 oder ein Band mit einem Ende 91 mit Abstand von dem Gelenk 92 an dem Hilfsstab 26 befestigt und mit beispielsweise gleichem Abstand von diesem Gelenk 92 über eine an dem Stützstab 50' bzw. an dessen unterem Stützstabelement 95 befestigte erste Rolle 93 geführt. Die Weiterführung des Drahtseiles 90 erfolgt über eine, zweite, am äusseren oder oberen Ende 96 des unteren Stützstablementes 95 befestigte Rolle 97 und nach Umlenkung um 180° bis zu einer Befestigungsstelle 98 am inneren oder unteren Ende 99 eines oberen Stützstabelementes 100. Das obere Stützstabelement 100 hat einen kleineren Querschnitt als das untere Stützstabelement 95, so dass es in letzerem teleskopartig geführt ist. Dabei kann an der Befestigungsstelle 98 für das andere Ende 101 des Seils 90 ein Gleit- und Distanzkörper 102 am Stützstabelement 100 befestigt sein und an der Innenwand des anderen Stützstabelementes 95 ein zweiten Gleit- und Distanzkörper vorgesehen sein, in dem das Drahtseil 90 geführt ist. Auf diese Weise kann das Drahtseil 90 zwischen den Profilwänden beider Stabelemente 95,100 geführt sein.As a drive for this telescopic support rod extension serves the scissor-like spreading movement between the Auxiliary rod 26 and the support rod 50 'during the upward movement of the lower sliding body 25 and the upper one Sliding body 27 takes place on the stop 54. For this is a wire rope 90 or tape with one end 91 at a distance attached by the hinge 92 to the auxiliary rod 26 and with for example the same distance from this joint 92 one on the support rod 50 'or on its lower support rod element 95 attached first roller 93 guided. The continuation of the wire rope 90 takes place via one, second, on the outside or upper end 96 of the lower support member 95 attached roller 97 and after deflection by 180 ° to one Attachment point 98 at the inner or lower end 99 of a upper support member 100. The upper support member 100 has a smaller cross section than the lower support rod element 95, making it telescopic in the latter is. It can be at the attachment point 98 for the other End 101 of the rope 90 a sliding and spacer 102 on Support rod element 100 and attached to the inner wall of the other support rod element 95 a second sliding and spacer be provided in which the wire rope 90 is guided is. In this way, the wire rope 90 can be between the profile walls of both rod elements 95, 100.

Bei zunehmender Aufwärtsbewegung des unteren Schiebekörpers 25 bewegt sich die erste Rolle 93 zunehmend von der Befestigungsstelle des Seilendes 91 am Hilfsstab 26 weg, so dass der sich somit ergebende Zug am Drahtseil 90 dazu führt, dass das obere Stützstabelement 100 teleskopartig aus dem unteren Stützstabelement herausgezogen wird. Entsprechend verlängert sich der Stützstab 50', so dass die verschiebbaren Stabelemente 5'' der Tragstäbe 1 zur Vergrösserung des Schirmes weit nach aussen geschoben werden.With increasing upward movement of the lower sliding body 25, the first roller 93 moves increasingly from the fastening point of the rope end 91 on the auxiliary rod 26 away, so that the resulting pull on the wire rope 90 leads to that the upper support rod element 100 telescopically from the lower support rod element is pulled out. Corresponding extends the support rod 50 'so that the displaceable Rod elements 5 '' of the support rods 1 to enlarge the Screen are pushed far out.

Zur Erleichterung des Zusammenschiebens und Zusammenfaltens des Schirmes sind entsprechend dem Ausführungsbeispiel nach Fig. 26 zwischen den Kopfenden 86 der Tragstäbe 1 und dem kopfseitigen Ende der verschiebbaren Stabelemente 5'' der Tragstäbe 1 Zugfedern 52 vorgesehen. Beim Ausführungsbeispiel nach Fig.35 wird diese Schirmbeweguhg durch zusätzliche Zugfedern 103 erleichtert, die das untere Ende 99 der oberen Stützstabelemente 100 mit einer weiter unten liegenden Stelle z.B. am Gelenk 92 des unteren Stützstabelementes 95 verbinden. Diese Zugfedern 103 wirken somit dem Zug des Drahtseiles 90 bzw. der Verlängerung der Stützstäbe 50' entgegen.To facilitate pushing and folding of the screen are according to the embodiment Fig. 26 between the head ends 86 of the support rods 1 and the head end of the displaceable rod elements 5 '' Support rods 1 tension springs 52 are provided. In the embodiment according to Fig. 35 this screen movement is done by additional Tension springs 103 facilitates the lower end 99 of the upper support rod elements 100 with a lower one Place e.g. on the joint 92 of the lower support rod element 95 connect. These tension springs 103 thus act on the train of the Wire rope 90 or the extension of the support rods 50 ' opposite.

Als Antrieb für die teleskopartige Verlängerungsbewegung der Stützstäbe über ein Zugseilsystem kann jede beim Spreizen der Vorrichtung auftretende Auseinanderbwegung von Elementen der Vorrichtung bzw. von Bereichen der Vorrichtung ausgenutzt werden, wie z.B. auch die Aufwärtsbewegung des unteren Gleitkörpers 25 relativ zu einem darunter angeordneten Stelle des Führungselementes 3.As a drive for the telescopic extension movement the support rods can be spread by a pull rope system the device spreading apart Elements of the device or areas of the device can be exploited, e.g. also the upward movement of the lower sliding body 25 relative to one arranged below Place of the guide element 3.

Die anhand der Fig.35 und 36 beschriebene Schirmkinematik lässt sich vorteilhaft auch für einen Schirm anwenden, der entsprechend der Darstellung in Fig.27, d.h ohne Verlängerbarkeit der Tragstäbe 1 ausgeführt ist.The screen kinematics described with reference to FIGS. 35 and 36 can also be used advantageously for a screen that as shown in Fig. 27, i.e. without extensibility the support rods 1 is executed.
