Description

Die Erfindung betrifft einen Standschirm zum Einsatz als Sonnenschirm, Gartenschirm, Marktschirm usw. Dieser Schirm weist ein zentrales Standrohr mit einem Schirmgestänge auf, sowie ein Schirmtuch als Dachhaut, welche im geöffneten Zustand die Dachstreben überspannt.The invention relates to a parasol for use as a parasol, garden umbrella, Market umbrella etc. This umbrella has a central standpipe with a Umbrella poles on, as well as an umbrella cloth as roof skin, which in the open Condition of the roof struts spanned.

Garten-, Sonnen- und Marktschirme sind in verschiedenen Ausführungen bekannt. Ein besonders weit entwickelter Schirm ist aus der PCT/DE92/00155 bekanntgeworden. Er weist drei Kronen auf, nämlich eine Endkrone, welche die Spitze des Schirmes bildet und sich beim Schliessen des Schirmes nach oben bewegt, eine in der Höhe fixe Krone, die fest am Standrohr montiert ist und für die Koordination der Schliess- und Oeffnungsbewegung des Schirmgestänges nötig ist, sowie eine Läuferkrone, an welcher die Schirmstreben angelenkt sind und die am Standrohr auf und ab bewegbar ist. Zwischen den Dachstreben und der fixen Krone sind dabei weitere Hilfsstreben angeordnet, welche ebenfalls eine Koordinationsaufgabe beim Oeffnen und Schliessen des Schirmes übernehmen. Bei der Oeffnungsbewegung laufen die beiden beweglichen Kronen aufeinander zu, das heisst die Endkrone bewegt sich abwärts und die Läuferkrone aufwärts und gleichzeitig werden die Dachstreben nach aussen gespreizt und spannen das Schirmtuch. Umgekehrt bewegt sich beim Schliessen die Endkrone nach aufwärts und die Läuferkrone nach abwärts, und die Dachstreben werden gegen unten zugeschwenkt. Diese Mechanik bringt kinetische Vorteile, weil der geöffnete Schirm nicht so hoch über dem Boden aufgespannt ist wie das der Fall wäre, wenn seine Endkrone stationär am Ende eines Standrohres angeordnet wäre. Die Konstruktion stösst aber an Grenzen, wenn sie für besonders grosse Schirme eingesetzt werden soll, oder wenn der Schirm möglichst leicht bedienbar sein soll. Bei grossen Schirmen werden die Kräfte zum Bedienen zu gross. Es werden aber zunehmend Schirme mit grossen Schirmflächen verlangt, und diese sollen aber leicht zu bedienen sein, das heisst mit wenig Kraftaufwand.Garden, sun and market umbrellas are available in different designs known. A particularly developed umbrella is from PCT / DE92 / 00155 known. It has three crowns, namely an end crown, which the The top of the umbrella forms and when the umbrella closes, it moves upwards moved, a height-fixed crown, which is fixed to the standpipe and for which Coordination of the closing and opening movement of the umbrella rod is necessary is, as well as a rotor crown to which the shield struts are articulated and the is movable up and down on the standpipe. Between the roof struts and the fixed Krone further auxiliary struts are arranged, which also have a coordination task when opening and closing the screen. In the Opening movement, the two movable crowns converge towards each other means the end crown moves down and the rotor crown up and at the same time the roof struts are spread outwards and tension that Screen cloth. Conversely, when closing, the end crown moves upwards and the runner crown down, and the roof struts go down pivoted closed. This mechanism brings kinetic advantages because of the open one The umbrella is not as high above the ground as it would be if its end crown were stationary at the end of a standpipe. The Construction has its limits, however, when it is used for particularly large umbrellas should be used, or if the screen should be as easy to use as possible. With large umbrellas, the forces to operate are too great. But there will be Umbrellas with large umbrella areas are increasingly required, but these should be easy to use, that means with little effort.

Ein weiterer Schirm, der dem Oberbegriff des Anspruchs 1 entspricht, ist in EP 0 392 989 A offenbart.Another screen that corresponds to the preamble of claim 1 is in EP 0 392 989 A. disclosed.

Es ist daher die Aufgabe der vorliegenden Erfindung, einen Standschirm dieser Art anzugeben, der mit weniger Kraftaufwand zu öffnen und zu schliessen ist.It is therefore the object of the present invention to provide a parachute Specify the type that can be opened and closed with less effort.

Diese Aufgabe wird gelöst von einem Standschirm mit einem Standrohr, einem Schirmgestänge aus Dachstreben, die an einer beweglichen Endkrone angelenkt sind, welche am oberen Ende eines Zugrohres sitzt, das längsverschiebbar im Standrohr geführt ist, weiter mit Stützstreben, welche mit ihrem oberen Ende an den Dachstreben zu deren Abstützung angelenkt sind und mit ihrem unteren Ende an einer am Standrohr verschiebbaren Läuferkrone angelenkt sind, sowie Hilfsstreben zur Koordination der Oeffnungs- und Schliessbewegung der Dachund Stützstreben, die zwischen einer stationären Krone, welche am oberen Standrohrende sitzt, und den Stützstreben gelenkig angeordnet sind, wobei sich dieser Standschirm dadurch auszeichnet, dass im Standrohr eine Stahl- oder Gasfeder zum teilautomatischen Oeffnen und Schliessen des Schirmes vorhanden ist, derart, dass die Endkrone teilautomatisch, das heisst mit wenig Kraftaufwand durch Bewegen einer Dachstrebe, unter Oeffnen des Schirmes in ihre unterste Position und zum Schliessen umgekehrt in ihre oberste Position bringbar ist.This problem is solved by a standing umbrella with a standpipe, a Umbrella frame made of roof struts, which are articulated on a movable end crown are, which sits at the upper end of a draw tube that is longitudinally displaceable in the Standpipe is guided, further with support struts, which with their upper end the roof struts are articulated to support them and with their lower end are articulated on a sliding crown movable on the standpipe, and Auxiliary struts for coordinating the opening and closing movements of the roof and Support struts between a stationary crown, which at the top Stand pipe end sits, and the support struts are articulated, whereby This standing umbrella is characterized by the fact that a steel or Gas spring for semi-automatic opening and closing of the umbrella is present, such that the end crown is semi-automatic, i.e. with little Exertion of force by moving a roof strut while opening the screen in their bottom position and vice versa to close to their top position is feasible.

In den Zeichnungen sind Ausführungsformen dieses Standschirmes als Beispiele dargestellt. Anhand dieser Zeichnungen wird nachfolgend der Standschirm beschrieben und seine Funktion erläutert wird. In the drawings, embodiments of this parachute are examples shown. The standing umbrella is described below with the aid of these drawings and its function is explained.

In Figur 1 ist der Schirm von der Seite her gesehen gezeigt, und zwar einmal in geschlossener und einmal in geöffneter Stellung. Er weist ein Standrohr 1 auf, das an seinem oberen Ende eine stationäre Krone 2 aufweist. Im Standrohr 1 steckt ein Zugrohr 3, das im Standrohr 1 verschiebbar ist und oben eine Endkrone 4 trägt. Am Standrohr 1, unterhalb der stationären Krone 3, ist eine Laufkrone 5 angeordnet, auf der sich Stützstreben 6 für die Dachstreben 7 des Schirmes abstützen, indem sie an dieser Laufkrone 5 angelenkt sind. Beim Oeffnen des Schirmes bewegt sich die Laufkrone 5 aufwärts und gleichzeitig bewegt sich die Endkrone 4, an der die Dachstreben 7 angelenkt sind, abwärts. Diese Gegenbewegung erfolgt aufgrund der Geometrie des Schirmgestänges, indem Hilfsstreben 8 zwischen der stationären Krone 2 und den Stützstreben 6 angeordnet sind. Die Dachstreben 7 tragen das Schirmtuch 25.In Figure 1, the screen is shown from the side, once in closed and once in the open position. It has a standpipe 1 that has a stationary crown 2 at its upper end. Stuck in standpipe 1 a draw tube 3 which is displaceable in the standpipe 1 and an end crown 4 at the top wearing. On the standpipe 1, below the stationary crown 3, there is a crown 5 arranged on which support struts 6 for the roof struts 7 of the screen are supported, by being articulated on this crown 5. When opening the Umbrella moves the crown 5 upwards and at the same time moves End crown 4, on which the roof struts 7 are articulated, downwards. This counter movement takes place due to the geometry of the umbrella rod, by auxiliary struts 8 are arranged between the stationary crown 2 and the support struts 6. The Roof struts 7 carry the umbrella cloth 25.

In Figur 2 ist das Schirmgestänge dieses Standschirmes deutlicher dargestellt. Es besteht aus dem Standrohr 1, in welchem von oben ein Zugrohr 3 hineingesteckt ist, das im Standrohr 1 auf- und abwärts verschiebbar geführt ist. Am oberen Ende des Standrohres 1 ist eine stationäre Krone 2 befestigt, an welcher Hilfsstreben 8 angelenkt sind. Am oberen Ende des Zugrohres 3 sitzt die Endkrone 4, an welcher die Dachstreben 7 angelenkt sind. Die Stützstreben 6 für das Stützen der Dachstreben 7 sind an einer Läuferkrone 5 angelenkt, welche am Standrohr 1 auf und ab bewegbar ist. Zum Oeffnen und Aufspannen des Schirmes muss die Endkrone 4 gegen abwärts bewegt werden, oder die Läuferkrone 5 muss gegen aufwärts bewegt werden. Weil die Stützstreben 6 über die Hilfsstreben 8 mit der fixen Krone 2 verbunden sind, wird die Bewegung der Dachstreben 7 beim Verschieben der beweglichen Kronen 4,5 in einer gewissen Weise erzwungen, nämlich so, dass sie beim Oeffnen gegen aussen gespreizt werden, und umgekehrt beim Schliessen des Schirmes zuklappen. Infolge der Geometrie dieser Anordnung der Dach- 7, Stütz- 6 und Hilfsstreben 8 kann nun zum Beispiel bloss die Endkrone 4 nach abwärts bewegt werden, und die Geometrie sorgt für eine Koordination der Bewegung der übrigen Teile, sodass die Dachstreben 7 dabei gespreizt werden und die Läuferkrone 5 sich nach aufwärts bewegt. In gleicher Weise wird das Schliessen des Schirmes durch einfaches Ausfahren des Zugrohres 3 und somit der Endkrone 4 bewirkt. Die Geometrie der Streben 6,7,8 bewirkt das Schliessen des Schirmes bzw. das Zusammenklappen der Dachstreben 7. Bei einem kleinen Schirm kann die Kraft zum Beispiel dadurch aufgebracht werden, dass die Endkrone 4 mittels eines Seiles nach unten gezogen wird, wodurch der Schirm geöffnet wird, oder aber man ergreift eine einzelne Dachstrebe 7 an ihrem Ende und schwenkt sie nach aussen und aufwärts, wodurch gleichzeitig die Endkrone 4 nach unten fährt und die Läuferkrone 5 nach aufwärts. Als dritte Variante kann auch die Läuferkrone 5 nach aufwärts bewegt werden. Dadurch werden die Dachstreben 7 nach aussen gespreizt und die Endkrone 4 bewegt sich abwärts. In Figure 2, the umbrella rod of this parachute is shown more clearly. It consists of the standpipe 1, in which a draw tube 3 is inserted from above is, which is guided in the standpipe 1 up and down. At the upper end of the standpipe 1, a stationary crown 2 is attached, on which auxiliary struts 8 are articulated. The end crown 4 is seated at the upper end of the draw tube 3 which the roof struts 7 are articulated. The support struts 6 for supporting the Roof struts 7 are articulated on a rotor crown 5, which on the standpipe 1 and is movable from. To open and open the umbrella, the End crown 4 to be moved downwards, or the rotor crown 5 must be against be moved upwards. Because the support struts 6 on the auxiliary struts 8 with the fixed crown 2 are connected, the movement of the roof struts 7 when moving of the movable crowns 4, 5 forced in a certain way, namely so that they are spread outwards when opened, and vice versa close when closing the umbrella. Due to the geometry of this arrangement the roof 7, support 6 and auxiliary struts 8 can now, for example, only the End crown 4 can be moved downwards, and the geometry ensures coordination the movement of the other parts, so that the roof struts 7 spread apart and the rotor crown 5 moves upwards. In the same The umbrella is closed simply by pulling out the draw tube 3 and thus the end crown 4 causes. The geometry of the struts 6,7,8 closing the umbrella or folding the roof struts 7. With a small screen, for example, the force can be applied by that the end crown 4 is pulled down by means of a rope, whereby the screen is opened, or one attacks a single roof strut 7 its end and swings it outwards and upwards, thereby simultaneously creating the End crown 4 moves down and the rotor crown 5 upwards. As a third variant the rotor crown 5 can also be moved upwards. This will the roof struts 7 spread outwards and the end crown 4 moves down.

Ueblicherweise werden solche Standschirme in Durchmessern von 3.8m, 4.4m, 5m, 5.6m und grösser hergestellt, jeweils in einer Abstufung von 60cm. Bei einem solch grossen Standschirm von zum Beispiel 3.8m Schirmdach-Durchmesser und mehr bereitet das Oeffnen und Schliessen des Schirmes von Hand Mühe. Deswegen weist der hier vorgestellte Standschirm eine Stahl- oder Gasfeder zum teiloder halbautomatischen Oeffnen und Schliessen auf.Usually, such parasols are available in diameters of 3.8m, 4.4m, 5m, 5.6m and larger, each in a gradation of 60cm. At a such a large parachute of, for example, 3.8m canopy diameter and opening and closing the screen by hand is more difficult. therefore the standing umbrella presented here has a steel or gas spring in part or semi-automatic opening and closing.

Dieser teilautomatische Standschirmes arbeitet mit einer mechanischen Feder oder einer Gasfeder. Mittels der Federkraft wird die obere Endkrone 4 aktiv gegen unten in Richtung zum Standrohr 1 hin gezogen, und als Folge davon bewegt sich die Läuferkrone 5 am Standrohr 1 aufwärts und die Dachstreben 7 werden gespreizt. Hierzu ist zum Beispiel eine Gasdruckfeder 9 im Standrohr 1 untergebracht, wie das in Figur 3 gezeigt ist. Die Gasdruckfeder 9 sitzt hier mit ihrem Zylinder 11 gegen oben und ihre Kolbenstange 10 fährt gegen unten aus und ist an ihrem Ende mit dem Zugrohr 3 verbunden. Im Detail ist der Gasdruckzylinder 11 mittels eines Bolzens 12 am Standrohr 1 verankert. Am unteren Ende der Kolbenstange 10 sitzt ebenfalls ein Bolzen 13, über den die Kolbenstange 10 fest mit dem Zugrohr 3 verbunden ist.This semi-automatic standing umbrella works with a mechanical spring or a gas spring. The upper end crown 4 is actively counteracted by means of the spring force pulled down towards the standpipe 1, and as a result moves the rotor crown 5 on the standpipe 1 upwards and the roof struts 7 spread. For this purpose, there is, for example, a gas pressure spring 9 in the standpipe 1 housed, as shown in Figure 3. The gas pressure spring 9 sits here their cylinder 11 towards the top and their piston rod 10 extends towards the bottom and is connected at its end to the draw tube 3. In detail is the gas pressure cylinder 11 anchored to the standpipe 1 by means of a bolt 12. At the bottom the piston rod 10 also has a bolt 13, via which the piston rod 10 is firmly connected to the draw tube 3.

In der nebenstehenden kleinen Figur 4 ist anhand eines Querschnittes gezeigt, wie dieser Bolzen 12 das Standrohr 1 durchsetzt, durch die Schlitze im Zugrohr 3 verläuft und den Gasdruckzylinder 11 hält, sodass dieser also fest mit dem Standrohr 1 verbunden ist.In the small figure 4 on the left, a cross section is shown, how this bolt 12 passes through the standpipe 1, through the slots in the draw tube 3 runs and holds the gas pressure cylinder 11 so that it is firmly attached to the Standpipe 1 is connected.

Wenn nun die Kolbenstange 10 ein- und ausfährt, bewegt sich das Zugrohr 3 innerhalb des Standrohres 1. Deshalb weist das Zugrohr 3 einen Schlitz 24 auf, sodass es über die Länge dieses Schlitzes 24 am stationären Bolzen 12 vorbeifahren kann. Im komprimierten Zustand der Gasfeder 9 ist also die Kolbenstange 10 eingefahren und der Schirm ist geschlossen. Die Endkrone 4 befindet sich in ihrer obersten Position. In der hier gezeigten Zeichnung ist die Endkrone noch mit einer Abdeckkappe 14 abgedeckt. Wenn nun die Kolbenstange 10 ausgefahren ist, wird der Zustand erreicht, der in der Figur 3 dargestellt ist. Der Schlitz 24 ist am Bolzen 12 nach unten vorbeigefahren, bis fast an sein Ende. Das Ende der Kolbenstange 10 hat das Zugrohr 3 mit sich nach unten gezogen und somit auch die Endkrone 4. Die an der Endkrone 4 angelenkten Dachstreben 7 sind damit aufgespreizt, wie angedeutet, und der Schirm somit aufgespannt. Unten am Standrohr 1 wurde durch die schon beschriebene Geometrie der Streben die Läuferkrone 5 mit den daran angelenkten Stützstreben nach oben bewegt und sie hat ihre oberste Position eingenommen. Dieser ganze Bewegungsablauf zur Oeffnung des Schirmes vollzieht sich fast von selbst. Man muss bloss das Ende einer Dachstrebe ergreifen und kann sozusagen mit einem Finger diese Dachstreben nach aussen ziehen und etwas nach aufwärts schwenken, wonach die Aufspannung des Schirmes von selbst erfolgt. Das ganze Oeffnen oder Aufspannen des Schirmes erfolgt daher teilautomatisch, mit einem durchaus zumutbaren Arbeits- bzw. Kraftaufwand. Umgekehrt sind die wirkenden Kräfte aufgrund der Geometrie und der Kraft der gewählten Gasdruckfeder so ausgewogen, dass auch das Schliessen des Schirmes mit einer sehr geringen Kraft möglich ist. Man ergreift wiederum das Ende einer Dachstrebe und klappt diese nach unten. Das erfolgt gegen die wirkende Kraft der Gasdruckfeder, was aber aufgrund der Geometrie nur eine sehr geringe Kraft erfordert. Den genau gleichen Effekt erzielt man selbstverständlich, indem man die Gasdruckfeder umgekehrt einbaut, sodass also die Kolbenstange stationär ist und somit der Gasdruckzylinder ausfährt und dabei das Zugrohr mit sich nach unten zieht. Anstelle einer Gasfeder kann auch eine mechanische Feder eingesetzt werden, die zum Beispiel im Standrohr ganz unten befestigt ist, und deren anderes Ende am Zugrohr befestigt ist. Wichtig ist, dass diese mechanische Feder über den gesamten zurückzulegenden Weg des Zugrohres eine etwa konstante Kraft entwickelt. Nötigenfalls kann man die Feder über die gesamte Schirmlänge spannen, das heisst von ganz unten im Standrohr bis an die Spitze des Schirmes, das heisst bis an die Endkrone.If the piston rod 10 now moves in and out, the draw tube 3 moves within of the standpipe 1. Therefore, the draw tube 3 has a slot 24, so that it passes the stationary bolt 12 over the length of this slot 24 can. The piston rod is in the compressed state of the gas spring 9 10 retracted and the screen is closed. The end crown 4 is in their top position. In the drawing shown here, the end crown is still with a cap 14 covered. If the piston rod 10 is now extended the state shown in FIG. 3 is reached. The slot 24 is drove past the bolt 12 down to almost its end. The end of Piston rod 10 has pulled the draw tube 3 down with it and thus also the end crown 4. The roof struts 7 articulated on the end crown 4 are thus spread out, as indicated, and thus the screen opened. Down on Standpipe 1 was the already described geometry of the struts Runner crown 5 with the hinged support struts moved up and it has taken her top position. This whole movement sequence for opening the screen is almost automatic. You just have to end one Take hold of the roof strut and, as it were, use a finger to grip this roof strut pull outwards and swing slightly upwards, after which the clamping the screen is done by itself. The whole opening or opening of the Umbrella is therefore semi-automatic, with a reasonable work or effort. The opposite forces are due to the geometry and the force of the selected gas pressure spring so balanced that that too Closing the screen with a very low force is possible. One seizes again the end of a roof strut and folds it down. That happens against the force of the gas pressure spring, but this is due to the geometry requires very little force. You get the exact same effect of course, by installing the gas spring upside down, so that the piston rod is stationary and thus the gas pressure cylinder extends and thereby pulls the draw tube down with it. Instead of a gas spring, a mechanical spring can be used, for example in the standpipe at the bottom is attached, and the other end is attached to the draw tube. It's important, that this mechanical spring over the entire distance to be covered Draw tube develops an approximately constant force. If necessary, you can use the spring Tension over the entire length of the umbrella, i.e. from the bottom in the standpipe to the top of the screen, that is to the end crown.

Das Spannen der Dachhaut erfolgt manuell. Hierfür ist ein Kniehebelmechanismus vorgesehen, der in Figur 5 und 6 dargestellt ist. Beim Oeffnen des Schirmes läuft ja die Laufkrone 5 aufwärts und zum Spannen der Dachhaut bzw. des Schirmtuches muss diese Laufkrone 5 noch einige Zentimeter weiter nach oben gespannt werden. Hierzu ist an dieser Laufkrone 5 ein Hebel 15 angelenkt, welcher vom Standrohr 1 aus gesehen leicht nach aussen abgewinkelt ist. Unterhalb der Zeichnung ist übrigens die Krone 5 von oben gesehen dargestellt. Am Ende des Hebels 15 trägt dieser eine Griffkugel 16. Am Ende des von der Läuferkrone 5 aus geraden Hebelteils 15 ist ein Kniehebel 17 angelenkt, welcher mittels einer Feder 18 federbelastet ist, sodass er stets in der gezeigten abgewinkelten Position gehalten wird. An seinem Ende weist dieser Kniehebel 17 einen Nocken 19 auf, welcher in eine Anzahl Löcher 20 passt, die in einer vertikal verlaufenden Reihe am Standrohr 1 vorhanden sind. In der Zeichnung ist allerdings nur ein einzelnes solches Loch 20 gezeigt. Wenn nun der Schirm kraft der Gasfeder oder mechanischen Feder praktisch geöffnet ist, ergreift man diesen Hebel 15 und führt den Kniehebel 17 mit seinem Nocken 19 in ein passendes Loch 20 und drückt dann den Hebel 15 gegen das Standrohr 1 hin, worauf kraft der Hebelwirkung des Kniehebels 17 sich die Läuferkrone 5 über den daran angelenkten Hebel 15 nach oben bewegt, bis der gerade Teil des Hebels 15 am Standrohr 1 anliegt. In dieser Position kann ein Splint in das Loch 21 am Hebel 15 gesteckt werden, der auch durch ein entsprechendes Loch 22 an der Verlängerung 23 der Läuferkrone 5 einpasst. Damit ist der Hebel 15 in dieser Lage gesichert und die Dachhaut gespannt, wie das in der Figur 6 gezeigt ist. Falls ein kräftigeres Spannen gewünscht wird, kann der Hebel 15 einfach mit seinem Kniehebel 17 mit einem höher angeordneten Loch 20 am Standrohr 1 in Eingriff gebracht und gespannt werden.The roof skin is tensioned manually. For this is an Toggle lever mechanism is provided, which is shown in Figures 5 and 6. At the Opening the screen, the crown 5 runs upwards and to tension the Roof skin or the umbrella cloth, this crown 5 must still a few centimeters be stretched further up. For this purpose, a lever 15 is on this crown 5 articulated, which seen from the standpipe 1 angled slightly outwards is. By the way, below the drawing the crown 5 is seen from above shown. At the end of the lever 15, this carries a grip ball 16. At the end of the a toggle lever 17 is articulated from the rotor crown 5 from a straight lever part 15, which is spring-loaded by means of a spring 18, so that it is always shown in the angled position is held. At its end, this toggle lever 17 a cam 19 which fits into a number of holes 20 which are vertical in a extending row on the standpipe 1 are available. In the drawing is however, only a single such hole 20 is shown. If the screen is now powerful the gas spring or mechanical spring is practically open, you grab it Lever 15 and guides the toggle lever 17 with its cam 19 into a suitable one Hole 20 and then pushes the lever 15 against the standpipe 1, whereupon force the leverage of the toggle lever 17, the rotor crown 5 over it Articulated lever 15 moves up until the straight part of the lever 15 on Standpipe 1 is applied. In this position, a split pin can be inserted in hole 21 on lever 15 be inserted, which also through a corresponding hole 22 on the Extension 23 of the rotor crown 5 fits. So that the lever 15 is in this Position secured and the roof skin stretched, as shown in Figure 6. If a stronger tensioning is desired, the lever 15 can simply with his toggle 17 with a higher hole 20 on the standpipe 1 in Be brought in and excited.

Claims (5)

  1. An upright shade comprising an upright tube (1), a shade structure made up of roof struts (7) which are joined to a mobile end crown (4) disposed at the top end of a push tube (3) which can be longitudinally displaced inside upright tube (1), also comprising supporting struts (6), which are connected at their top ends to roof struts (7) in order to provide support, and at their bottom ends to a runner crown (5) which can be displaced along upright tube (1), and further comprising auxiliary struts (8) to coordinate the opening and closing movements of the roof struts (7) and supporting struts (6), said auxiliary struts being articulated, and arranged between a stationary crown (2) disposed at the top end of upright tube, and the supporting struts (6), characterized in that a steel or pneumatic spring is fitted inside upright tube (1) for semi-automatic opening and closing of the shade, said spring being connected with the upright tube (1) and the push tube (3) in such way that the end crown (4) is semi-automatically moveable - i.e. with little expenditure of effort - by displacing one roof strut (7) into its lowest position, thereby opening the shade, or into its uppermost position, thereby closing the shade.
  2. The upright shade of claim 1, characterized in that a gas pressure spring (9) is fitted inside the upright tube so that its cylinder (11) is securely connected to upright tube (1), and the end of its piston rod (10) is securely connected to push tube (3) in such a manner that by manually initiating the opening movement of roof struts (7), the extension of piston rod (10) under the effect of the pneumatic spring moves push tube (3) with the end crown (4) mounted on its end, downwards towards its lowest position, thereby opening the shade.
