Description

Technisches GebietTechnical field

Die Erfindung betrifft einen Schirmstock gemäss Oberbegriff des Anspruches 1 sowie einen Schirm gemäss Anspruch 19.The invention relates to an umbrella stick according to the preamble of claim 1 and an umbrella according to claim 19.

Stand der TechnikState of the art

Ein Schirmstock beziehungsweise ein Schirm der eingangs genannten Art ist beispielsweise aus der CH-A-661 189 bekannt, wobei der Seiltrieb aus einem Flaschenzug besteht, der zwischen dem Schieber und der Krone des Schirmes angeordnet ist. Der Flaschenzug ist umständlich zu handhaben, wobei insbesondere bei grösseren Schirmen die Zugänglichkeit in geschlossenem Zustand des Schirmes erschwert ist. Ausserdem liegt der Flaschenzug frei, so dass die Seillängen des Flaschenzuges bei geöffnetem Schirm schwierig abzulegen sind und das Erscheinungsbild des geöffneten Schirmes beeinträchtigen.A canopy or an umbrella of the type mentioned is known for example from CH-A-661 189, the cable drive consisting of a pulley block which is arranged between the slider and the crown of the umbrella. The pulley is difficult to handle, with access to the umbrella in the closed state being made more difficult, particularly with larger umbrellas. In addition, the pulley is exposed, so that the rope lengths of the pulley are difficult to put down when the screen is open and impair the appearance of the open screen.

Aus der CH-A-367 290 und 666 166 sind Schirme bekannt, die jeweils mittels eines Kugelgelenkes abnehmbar an einem Ausleger angehängt sind, der sich quer zu einem Ständer erstreckt. Das Öffnen des Schirmes erfolgt von Hand, wobei man das Schirmdach zunächst von Hand etwas öffnen muss, damit man dann von unten in den Schirm eingreifen und den Schieber erfassen kann, um ihn gegen die Krone des Schirmes zu bewegen und in geöffnetem Zustand mit dieser zu verrasten. Insbesondere bei grossen Schirmen ist dieser Öffnungsvorgang sehr mühevoll, da relativ grosse Kräfte erforderlich sind und überdies die Zugänglichkeit erschwert ist.From CH-A-367 290 and 666 166 umbrellas are known, each of which is detachably attached by means of a ball joint to an extension arm which extends transversely to a stand. The umbrella is opened by hand, whereby you first have to open the umbrella roof a bit by hand so that you can then reach into the umbrella from below and grasp the slide to move it against the crown of the umbrella and in the open state with it lock. This opening process is particularly difficult with large umbrellas, since relatively large forces are required and, moreover, access is difficult.

Es sind auch Schirme bekannt, die an einem mit einem Ständer verbundenen Ausleger angeordnet sind und über einen Seilzug geöffnet und geschlossen werden können. Ein Ende des Seilzuges ist mit dem Schieber des Schirmes verbunden. Das Seil des Seilzuges verläuft dann über die Krone und den Ausleger bis zu einer Seilwinde im Ständer oder Ausleger. Ein solcher Schirm ist zwar einfach zu handhaben, aber der Schirm kann nicht vom Ausleger abgenommen werden, wie dies bei den oben erwähnten Schirmen der Fall ist, ohne dass die Seilverbindung gelöst werden muss.Umbrellas are also known which are arranged on a boom connected to a stand and can be opened and closed by means of a cable. One end of the cable is connected to the slider of the screen. The cable of the cable pull then runs over the crown and the extension to a winch in the stand or extension. Such an umbrella is easy to use, but the umbrella cannot be removed from the boom, like this is the case with the above-mentioned umbrellas without having to loosen the cable connection.

Darstellung der ErfindungPresentation of the invention

Aufgabe der Erfindung ist es, einen Schirmstock der eingangs genannten Art zu schaffen, mit dem hängende Schirme verbessert werden können.The object of the invention is to provide a umbrella stick of the type mentioned, with which hanging umbrellas can be improved.

Diese Aufgabe wird erfindungsgemäss gelöst durch die Merkmale der Ansprüche 1 beziehungsweise 19.This object is achieved according to the invention by the features of claims 1 and 19, respectively.

Dadurch, dass der Seiltrieb als eine mit dem Schieber zu verbindende Seilwinde ausgebildet ist und das Seil koaxial mit der Stockachse verläuft, ergibt sich ein Antrieb, der leicht zugänglich ist, leicht zu bedienen ist und sich überdies in die Konstruktion des Schirmes harmonisch einfügt. Insbesondere ist das Seil im Schirmstock geschützt untergebracht, sodass umständliche Ablagen entfallen und das Erscheinungsbild des geöffneten Schirmes nicht gestört wird. Ausserdem ermöglicht ein solcher Schirmstock einen Schirm, der von einem Ausleger abgenommen werden kann, ohne auch die Seilverbindung lösen zu müssen. Ausserdem behindert der Schirmstock ein Aus- und Einfahren des Auslegers nicht.The fact that the cable drive is designed as a cable winch to be connected to the slider and the cable runs coaxially with the axis of the pole results in a drive that is easily accessible, easy to use and, moreover, fits harmoniously into the construction of the screen. In particular, the rope is protected in the umbrella stick, so that cumbersome storage is no longer necessary and the appearance of the open umbrella is not disturbed. In addition, such a umbrella stick enables an umbrella that can be removed from a boom without having to loosen the cable connection. In addition, the umbrella stick does not hinder extension and retraction of the boom.

Die Seilwinde kann in beliebiger Form direkt oder indirekt an einem Schieber angeordnet werden oder sein, vorteilhaft ist jedoch die Ausbildung nach Anspruch 2, da dann die Seilwinde mittels des Stockteiles in eine Öffnung des Schiebers eines Schirmes eingesetzt und mit diesem verbunden werden kann. Der Stockteil kann ausschliesslich dem Schieber zugeordnet sein und beim Öffnen des Schirmes mit einer Öffnung in der Krone verrasten. Vorteilhaft ist jedoch eine Ausgestaltung nach Anspruch 3 wonach der Stockteil mit der Krone des Schirmes verbindbar ist. Besonders bevorzugt ist eine Ausgestaltung nach Anspruch 4, wobei sowohl dem Schieber wie der Krone ein Stockteil zugeordnet wird, die in geöffnetem Zustand des Schirmes miteinander kuppelbar sind, wobei vorzugsweise ein Stockteil einen profilierten Zapfen und der andere Stockteil eine Buchse mit dem entsprechenden Gegenprofil aufweisen, sodass über die Stockteile ein Drehmoment übertragbar ist.The cable winch can be arranged in any form directly or indirectly on a slider or be, but the embodiment according to claim 2 is advantageous, since then the cable winch can be inserted into an opening of the slider of a screen and connected to it by means of the stick part. The cane part can only be assigned to the slider and lock with an opening in the crown when the screen is opened. However, an embodiment according to claim 3 is advantageous, according to which the stick part can be connected to the crown of the screen. An embodiment according to claim 4 is particularly preferred, wherein a stick part is assigned to both the slider and the crown, which can be coupled to one another in the open state of the screen, wherein preferably one stick part has a profiled pin and the other stick part a socket with the corresponding Have a counter profile so that a torque can be transmitted via the pole parts.

Die Seilwinde kann mit einem elektrischen Antrieb ausgerüstet sein. Vorteilhafter ist jedoch die Ausbildung nach Anspruch 5 mit einer Handkurbel. Zweckmässigerweise ist die Seilwinde nach Anspruch 6 mit einer Rastvorrichtung zum Verrasten beim Öffnen des Schirmes ausgestattet sowie nach Anspruch 7 mit einer Bremsvorrichtung zum kontrollierten Schliessen des Schirmes. Vorteilhafterweise sind die Rastvorrichtung sowie die Bremsvorrichtung gemäss Anspruch 8 miteinander kombiniert und durch die Handkurbel bedienbar. Die Ansprüche 9 bis 11 umschreiben vorteilhafte Ausgestaltungen dieser kombinierten Rast- und Bremsvorrichtung. Besonders zweckmässig sind Weiterbildungen nach den Ansprüchen 12 bis 15, wonach der Rastvorrichtung eine Freilaufvorrichtung zugeordnet ist, welche die Bremsvorrichtung und die Rastvorrichtung ausschaltet und ein schnelles Schliessen des Schirmes ermöglicht.The cable winch can be equipped with an electric drive. However, the embodiment according to claim 5 with a hand crank is more advantageous. Advantageously, the cable winch is equipped according to claim 6 with a locking device for locking when opening the screen and according to claim 7 with a braking device for controlled closing of the screen. The latching device and the braking device are advantageously combined with one another and can be operated by the hand crank. The claims 9 to 11 describe advantageous embodiments of this combined locking and braking device. Developments according to claims 12 to 15 are particularly expedient, according to which the latching device is assigned a freewheel device which switches off the braking device and the latching device and enables the screen to be closed quickly.

Besonders vorteilhaft ist die Ausgestaltung des Schirmstockes nach Anspruch 16 mit einem Haltegriff und insbesondere in dessen ringartiger Weiterbildung nach Anspruch 17, da der Haltegriff das Erfassen des Schiebers und damit der Seilwinde erleichtert, ohne dass der Benutzer erst in den Schirm eingreifen und diesen voröffnen muss. Der Haltegriff erleichtert auch die Bedienung der Seilwinde mit der Handkurbel. Insbesondere der ringartige Haltegriff deckt im übrigen die Handkurbel ab, wenn diese nach unten weist, wodurch einerseits die Handkurbel vor Beschädigungen und andererseits der Benutzer vor Verletzungen durch eine vorstehende Handkurbel geschützt wird. Der Haltegriff kann überdies eine zusätzliche Bedienungsfunktion zur Übertragung eines Drehmomentes übernehmen, um beispielsweise den Stockteil nach Anspruch 18 mit einem Gewindebolzen in eine Krone des Schirmes einzuschrauben und mit einem Kugelgelenk zusammenzuwirken, um das Kugelgelenk zu blockieren oder frei zu geben.The configuration of the umbrella pole according to claim 16 with a handle and in particular in its ring-like development according to claim 17 is particularly advantageous, since the handle makes it easier to grasp the slide and thus the cable winch without the user having to first intervene in the umbrella and open it. The handle also makes it easier to operate the winch with the hand crank. In particular, the ring-shaped handle covers the hand crank when it points downwards, thereby protecting the hand crank from damage on the one hand and protecting the user from injury from a protruding hand crank on the other hand. The handle can also take over an additional operating function for transmitting a torque, for example, to screw the stick part according to claim 18 with a threaded bolt into a crown of the screen and to cooperate with a ball joint to block or release the ball joint.

Der Schirmstock kann als selbständiges Bauelement ausgeführt sein und zum nachträglichen Einbau beziehungsweise Austausch eines Schirmstockes an einem bestehenden Schirm dienen, um bei einem solchen Schirm die eingangs erwähnten Nachteile zu beseitigen und Vorteile zu erzielen. Allerdings kann ein Schirm auch direkt mit dem erfindungsgemässen Schirmstock ausgerüstet sein.The umbrella stick can be designed as an independent component and for subsequent installation or replacement of a umbrella stick on one Existing screen are used to eliminate the disadvantages mentioned at the beginning and to achieve advantages with such a screen. However, a screen can also be equipped directly with the umbrella stick according to the invention.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention

Die Figur 1 zeigt einen Schirm 2 in geschlossenem Zustand, der an einem Ausleger 4 angeordnet ist, welcher ausfahrbar an einem Ständer 6 befestigt ist. Ein solcher Schirm ist beispielsweise aus der CH-A-367 290 und 666 166 bekannt.Figure 1 shows a screen 2 in the closed state, which is arranged on a boom 4 which is extendably attached to a stand 6. Such an umbrella is known for example from CH-A-367 290 and 666 166.

Dieser bekannte Schirm 2 weist ein Schirmgestell auf, das eine Krone 8 enthält, die über ein Kugelgelenk 10 mit dem Ausleger 4 verbunden ist. An der Krone 8 sind Dachstangen 12 angelenkt, die sich über Stützstangen 14 an einem Schieber 16 abstützen. Der Schieber 16 und die Krone 8 sind über einen Schirmstock 18 miteinander verbunden.This known umbrella 2 has an umbrella frame which contains a crown 8 which is connected to the boom 4 via a ball joint 10. Roof rods 12 are articulated to the crown 8 and are supported on a slide 16 via support rods 14. The slider 16 and the crown 8 are connected to each other via a screen stick 18.

Der nach der Erfindung ausgebildete Schirmstock 18 enthält einen ersten unteren Stockteil 20, der mit dem Schieber 6 verbunden ist, wobei er in eine Öffnung des Schiebers 16 eingesetzt und mittels einer Sicherung 21 gegen Herausgleiten gesichert ist. Am unteren Ende des Stockteiles ist eine Seilwinde 22 angeordnet, die durch eine Handkurbel 24 betätigt wird. Weiter enthält der Schirmstock 18 einen zweiten oberen Stockteil 26, der mit der Krone 8 verbunden ist. Bei geschlossenem Schirm gemäss Figur 1 sind der erste Stockteil 20 und der zweite Stockteil 26 voneinander getrennt und nur über ein Seil 28 der Seilwinde 22 miteinander verbunden. Bei geöffnetem Schirm sind die Stockteile 20 und 26 über eine Kupplungsvorrichtung 30 miteinander verbunden, wie dies aus den Figuren 2 und 3 hervorgeht. Die Kupplungsvorrichtung 30 wird gebildet durch einen profilierten Zapfen 32 an einem der Stockteile 20, der mit einer Buchse 34 des anderen Stockteiles 26 zusammenwirkt, wobei die Buchse mit einem entsprechenden Gegenprofil 36 ausgestattet ist, um eine drehfeste Verbindung zwischen den Stockteilen 20, 26 zu erzielen. Das Seil 28 ist durch die hohl ausgebildeten Stockteile 20, 26 im wesentlichen koaxial zur Achse 35 geführt und auf der Innenseite der Buchse 34 der Kupplungsvorrichtung 30 mittels einer Plombe 37 oder eines Knotens befestigt.The umbrella stick 18 designed according to the invention contains a first lower stick part 20 which is connected to the slide 6, wherein it is inserted into an opening of the slide 16 and is secured against sliding out by means of a fuse 21. At the lower end of the stick part a cable winch 22 is arranged, which is operated by a hand crank 24. Furthermore, the umbrella stick 18 contains a second upper stick part 26, which is connected to the crown 8. When the screen according to FIG. 1 is closed, the first floor part 20 and the second floor part 26 are separated from one another and are only connected to one another via a cable 28 of the cable winch 22. When the screen is open, the pole parts 20 and 26 are connected to one another via a coupling device 30, as can be seen from FIGS. 2 and 3. The coupling device 30 is formed by a profiled pin 32 on one of the stick parts 20, which cooperates with a socket 34 of the other stick part 26, the socket being equipped with a corresponding counter profile 36 in order to achieve a rotationally fixed connection between the stick parts 20, 26 , The cable 28 is guided through the hollow-shaped stick parts 20, 26 essentially coaxially to the axis 35 and fastened on the inside of the bush 34 of the coupling device 30 by means of a seal 37 or a knot.

Einzelheiten der Ausbildung des Schirmstockes 18 sind den Figuren 3 und 4 zu entnehmen.Details of the design of the umbrella pole 18 can be found in FIGS. 3 and 4.

Der erste Stockteil 20 weist die Seilwinde 22 mit der Handkurbel 24 auf. Ferner ist der erste Stockteil 20 mit einem ringartigen Haltegriff 38 ausgestattet, der sich quer zur Achse der Seilwinde 22 nach unten erstreckt und am Gehäuse 40 der Seilwinde angeformt ist. Im vorliegenden Beispiel sind der erste Stockteil 20, das Gehäuse 40 der Seilwinde 22 und der ringartige Haltegriff 38 einstückig ausgestaltet und sie werden aus zwei Formhälften 42a und 42b gebildet, die in einer vertikalen Mittelebene 44 aneinanderliegen, welche quer zur Achse der Seilwinde 22 ausgerichtet ist.The first floor part 20 has the cable winch 22 with the hand crank 24. Furthermore, the first floor part 20 is equipped with a ring-like handle 38 which extends downward transversely to the axis of the cable winch 22 and is integrally formed on the housing 40 of the cable winch. In the present example, the first floor part 20 is the The housing 40 of the cable winch 22 and the ring-like handle 38 are made in one piece and they are formed from two mold halves 42a and 42b which lie against one another in a vertical central plane 44 which is oriented transversely to the axis of the cable winch 22.

Die Seilwinde 22 wird gebildet aus der Handkurbel 24, die an einer Achse 46 befestigt ist, welche in einer Seiltrommel 48 gelagert ist. Die Seiltrommel ihrerseits ist in Lagerplatten 50a, 50b des Gehäuses 40 gelagert. Die Seiltrommel dient zum Auf- und Abwickeln des Seiles 28. Die Seilwinde 22 ist mit einer Rastvorrichtung 52 ausgestattet, um das Schirmgestell und damit den Schirm in geöffnetem Zustand zu halten. Diese Rastvorrichtung ist mit einer Bremsvorrichtung 54 kombiniert, die ein kontrolliertes Schliessen des Schirmes ermöglicht.The cable winch 22 is formed from the hand crank 24, which is attached to an axis 46, which is mounted in a cable drum 48. The cable drum in turn is mounted in bearing plates 50a, 50b of the housing 40. The cable drum is used to wind and unwind the cable 28. The cable winch 22 is equipped with a locking device 52 in order to keep the umbrella frame and thus the umbrella in the open state. This locking device is combined with a braking device 54, which enables a controlled closing of the screen.

Die Rastvorrichtung 52 besteht aus einem auf der Seiltrommel 48 frei drehbaren Rastkranz 56, an dem eine Klinke 58 angreift, die im Gehäuse 40 gelagert ist und mittels einer Feder 60 gegen den Rastkranz vorgespannt ist. Die Achse 46 steht über einen Flansch 62 und eine Bremsscheibe 64 an dem Rastkranz 56 an. Die koaxial in einer Öffnung 66 der Seiltrommel 48 angeordnete Achse 46 ist über eine Gewindeverbindung mit dieser verbunden und weist hierzu ein Aussengewinde 68 auf, das mit einem Innengewinde 70 der Öffnung 66 der Seiltrommel zusammenwirkt.The locking device 52 consists of a locking ring 56 which can be freely rotated on the cable drum 48 and which is engaged by a pawl 58 which is mounted in the housing 40 and is biased against the locking ring by means of a spring 60. The axis 46 is in contact with the locking ring 56 via a flange 62 and a brake disk 64. The axis 46 arranged coaxially in an opening 66 of the cable drum 48 is connected to the latter via a threaded connection and for this purpose has an external thread 68 which cooperates with an internal thread 70 of the opening 66 of the cable drum.

Die Funktionsweise der Seilwinde 22 mit der Rastvorrichtung 52 und der Bremsvorrichtung 54 ist wie folgt:The function of the cable winch 22 with the locking device 52 and the braking device 54 is as follows:

Wird die Handkurbel 24 zum Öffnen des Schirmes im Uhrzeigersinn gedreht, so wird das Aussengewinde 68 der Achse 46 weiter in das Innengewinde 70 der durch den Zug des Seiles 28 gebremsten Seiltrommel 48 eingeschraubt, wodurch der Flansch 62 der Achse 46 die Bremsscheibe 64 gegen den Rastkranz 56 presst und diesen auf der Seiltrommel 48 fixiert. Dadurch wird die Handkurbel 24 mit der Seiltrommel 48 verbunden und das Seil 28 kann aufgewickelt werden, wobei die Rastklinke 58 am Rastkranz 56 ein Zurückdrehen der Seiltrommel verhindert. Soll der Schirm geschlossen werden, so wird die Handkurbel 24 im Gegenuhrzeigersinn bewegt, wodurch die Achse 46 über das Aussengewinde 68 aus der Seiltrommel 48 herausgeschraubt wird und sich die Pressung des Flansches 62 an der Bremsscheibe 64 im Sinne einer Rutschkupplung lockert. Sobald die Bremskraft der Bremsscheibe 64 kleiner wird als die Zugkraft des Seils 28 an der Seiltrommel 48 ist die Wirkung der Rastvorrichtung 52 ausgeschaltet und das Seil 28 beginnt von der Seiltrommel 48 abzulaufen. Wird die Handkurbel 24 angehalten, so bewirkt die Zugkraft des Seiles ein Weiterdrehen der Seiltrommel 48 und damit ein Festziehen des Aussengewindes 68 und des Innengewindes 70, wodurch sich die Bremskraft an der Bremsscheibe 64 vergrössert bis die Seiltrommel 48 zum Stillstand kommt. Erst durch erneutes Zurückdrehen der Handkurbel 24 im Gegenuhrzeigersinn kann das Abrollen des Seiles 28 und damit das Schliessen des Schirmes wieder in Gang gesetzt werden. Auf diese Weise ist ein kontrolliertes Schliessen des Schirmes möglich.If the hand crank 24 is rotated clockwise to open the screen, the external thread 68 of the axis 46 is screwed further into the internal thread 70 of the cable drum 48 braked by the pull of the cable 28, whereby the flange 62 of the axis 46 brakes the brake disk 64 against the locking ring 56 presses and fixes this on the cable drum 48. As a result, the hand crank 24 is connected to the cable drum 48 and the cable 28 can be wound up, the latching pawl 58 on the latching ring 56 preventing the cable drum from turning back. Should the screen is closed, the crank handle 24 is moved counterclockwise, whereby the axis 46 is unscrewed from the cable drum 48 via the external thread 68 and the pressure of the flange 62 on the brake disc 64 loosens in the sense of a slip clutch. As soon as the braking force of the brake disk 64 becomes smaller than the tensile force of the rope 28 on the rope drum 48, the action of the locking device 52 is switched off and the rope 28 begins to run off the rope drum 48. If the hand crank 24 is stopped, the tensile force of the rope causes the rope drum 48 to turn further and thus tighten the external thread 68 and the internal thread 70, as a result of which the braking force on the brake disk 64 increases until the cable drum 48 comes to a standstill. Only by turning the crank handle 24 counterclockwise again can the unwinding of the rope 28 and thus the closing of the screen be started again. In this way, a controlled closing of the screen is possible.

Für ein rasches Schliessen des Schirmes ist die Seilwinde 22 noch mit einer Freilaufvorrichtung 71 mit einer Freilauftaste 72 ausgestattet, die auf der der Handkurbel 24 abgewandten Seite des Gehäuses 40 angeordnet ist. Die Freilauftaste 72 enthält einen Haltestift 74, der gegen ein Arretierprofil 76 der Seiltrommel 48 entgegen der Kraft einer Vorspannfeder 78 bewegbar ist. Die Freilaufvorrichtung 71 enthält nun weiter eine auf der der Handkurbel 24 abgewandten Seite der Achse 46 angeordnete Achsverlängerung 80 mit einer Blockiervorrichtung 81, die einen Anschlag 82 trägt, der über eine Feder 84 mit der zugewandten Stirnseite 86 der Seiltrommel 48 zusammenwirkt. Die Achsverlängerung 80 weist ein Gewinde 88 auf, welches den als Mutter ausgebildeten Anschlag 82 trägt. Ein Sicherungsring 90 mit einer radial nach innen weisenden Rastnase greift in eine Nut 92 in der Achsverlängerung 80 der Achse ein, um ein ungewolltes Verstellen des Anschlages 82 zu verhindern.For a quick closing of the screen, the cable winch 22 is also equipped with a freewheel device 71 with a freewheel button 72, which is arranged on the side of the housing 40 facing away from the hand crank 24. The freewheel button 72 contains a holding pin 74 which can be moved against a locking profile 76 of the cable drum 48 against the force of a biasing spring 78. The freewheel device 71 now also contains an axle extension 80 arranged on the side of the axis 46 facing away from the hand crank 24 with a blocking device 81 which carries a stop 82 which cooperates with the facing end face 86 of the cable drum 48 via a spring 84. The axis extension 80 has a thread 88 which carries the stop 82 designed as a nut. A locking ring 90 with a radially inward-facing locking lug engages in a groove 92 in the axle extension 80 of the axle in order to prevent an unintentional adjustment of the stop 82.

Die Funktionsweise der Freilaufvorrichtung 71 ist wie folgt:The function of the freewheel device 71 is as follows:

Beim Betätigen der Freilauftaste 72 wird der Haltestift 74 mit dem Arretierprofil 76 der Seiltrommel 48 in Eingriff gebracht und die Seiltrommel 48 blockiert. In diesem Zustand kann die Handkurbel 24 im Gegenuhrzeigersinn weiter gedreht werden, bis das Aussengewinde 68 und das Innengewinde 70 soweit gelöst sind, dass keine Reibverbindung zwischen der Bremsscheibe 64 und dem Rastkranz 56 besteht. Gleichzeitig presst dabei der Anschlag 82 die Feder 84 gegen die Stirnseite 86 der Seiltrommel 48, sodass die Seiltrommel 48 und die Achse 46 blockiert sind und sich das Aussengewinde 68 und das Innengewinde 70 nicht mehr relativ zueinander bewegen können. Dadurch wird verhindert, dass die Bremsscheibe 64 an dem Rastkranz 56 wirksam werden kann. Wird nun die Freilauftaste 72 los gelassen, so rollt das Seil 28 unter der Zugkraft des Seiles 28 von der Seiltrommel 48 ab und dreht die Seiltrommel 48 und die mit dieser verbundene Handkurbel. Die Blockierung der Blockiervorrichtung 81 wird aufgehoben und die Bremsvorrichtung 54 und die Rastvorrichtung 52 werden wieder aktiviert, wenn die Handkurbel 24 bei erhöhtem Seilzug im Uhrzeigersinn, das heisst in Öffnungsrichtung des Schirmes bewegt wird, wodurch der Anschlag 82 von der Stirnseite 86 frei kommt und die Klemmwirkung der Bremsscheibe 64 wieder zu wirken beginnt.When the freewheel button 72 is actuated, the holding pin 74 is brought into engagement with the locking profile 76 of the cable drum 48 and the cable drum 48 is blocked. In this state, the hand crank 24 can be rotated further counterclockwise until the external thread 68 and the internal thread 70 are loosened to such an extent that there is no frictional connection between the brake disk 64 and the locking ring 56. At the same time, the stop 82 presses the spring 84 against the end face 86 of the cable drum 48, so that the cable drum 48 and the axis 46 are blocked and the external thread 68 and the internal thread 70 can no longer move relative to one another. This prevents the brake disk 64 from being able to take effect on the locking ring 56. If the freewheel button 72 is now released, the rope 28 rolls under the tensile force of the rope 28 from the rope drum 48 and rotates the rope drum 48 and the crank handle connected to it. The blocking of the blocking device 81 is released and the braking device 54 and the latching device 52 are reactivated when the hand crank 24 is moved clockwise with an increased cable pull, that is to say in the opening direction of the screen, as a result of which the stop 82 comes free from the end face 86 and the Clamping effect of the brake disc 64 begins to take effect again.

Wie aus den Figuren 1 und 2 hervorgeht, ist der zweite Stockteil 26 mit der Krone 8, die am Kugelgelenk 10 befestigt ist, verbunden. Hierzu weist der obere Stockteil 26 einen Gewindebolzen 94 auf, der in eine Gewindeöffnung 96 der Krone 8 eingeschraubt ist. Die Krone ist mit einer Kugelpfanne 98 über einen hier nicht näher dargestellten Bajonettverschluss verbunden (Details hierzu können aus der CH-A-666 166 entnommen werden). Der Gewindebolzen 94 kann nun soweit in die Krone 8 beziehungsweise die Kugelpfanne 98 eingeschraubt werden, dass er direkt oder indirekt über ein Zwischenglied mit dem Kugelkopf 100 des Kugelgelenks 10 in Eingriff kommt. Durch Drehen am ringartigen Haltegriff 38 im Uhrzeigersinn kann der Gewindebolzen 94 gegen den Kugelkopf 100 vorgespannt werden und das Kugelgelenk 10 arretieren, wodurch der Schirm in einer gewünschten Lage festgestellt werden kann. Durch Drehen des ringartigen Haltegriffes 38 im Gegenuhrzeigersinn kann diese Blockade wieder aufgehoben werden und der Schirm am Ausleger 4 frei schwingen. Durch weiteres Zurückdrehen des ringartigen Haltegriffes 38 im Gegenuhrzeigersinn kann der Gewindebolzen 94 die Verbindung zum Kugelgelenk soweit öffnen, dass die Krone 8 in nicht dargestellter Weise durch Lösen des Bajonettverschlusses vom Kugelgelenk abgenommen werden kann.As can be seen from FIGS. 1 and 2, the second stick part 26 is connected to the crown 8, which is fastened to the ball joint 10. For this purpose, the upper stick part 26 has a threaded bolt 94 which is screwed into a threaded opening 96 of the crown 8. The crown is connected to a ball socket 98 via a bayonet lock (not shown in more detail here) (details on this can be found in CH-A-666 166). The threaded bolt 94 can now be screwed into the crown 8 or the ball socket 98 to such an extent that it engages directly or indirectly with the ball head 100 of the ball joint 10 via an intermediate member. By turning the ring-like handle 38 clockwise, the threaded bolt 94 can be biased against the ball head 100 and lock the ball joint 10, whereby the screen can be locked in a desired position. By turning the ring-shaped handle 38 counterclockwise, this blockage can be removed again and the screen on the arm 4 can swing freely. By turning back the ring-like handle 38 in the counterclockwise direction, the threaded bolt 94 can open the connection to the ball joint to such an extent that the crown 8 can be removed from the ball joint in a manner not shown by loosening the bayonet catch.

Die Figuren 5 und 6 zeigen ein weiteres Ausführungsbeispiel eines Schirmstockes 18a an einem Schirm 2a und zwar in Abwandlung des Schirms gemäss der CH-A-661 189. Der mit der Seilwinde 22 verbundene erste Stockteil 20a ist nur sehr kurz ausgebildet und dient ausschliesslich zum Befestigen in einer Öffnung 102 des Schiebers 16a. Der zweite Stockteil 26a ist mit der Krone 8a verbunden und in dieser in axialer Richtung verschiebbar geführt. Der zweite Stockteil weist eine Öse 104 auf, mittels der er an einem Haken 106 eines Auslegers einhängbar ist. Der zweite Stockteil 26a ist über eine Arretierhülse 108 in der Krone 8a geführt. Hierzu ist der zweite Stockteil 26a mit einem axialen Langloch 110 ausgestattet, durch das ein Bolzen 112 greift, der die Arretierhülse 108 durchdringt und in der Krone 8a befestigt ist.FIGS. 5 and 6 show a further exemplary embodiment of a canopy 18a on a canopy 2a, specifically in a modification of the canopy according to CH-A-661 189. The first cane part 20a connected to the cable winch 22 is only very short and is used exclusively for fastening in an opening 102 of the slide 16a. The second stick part 26a is connected to the crown 8a and is guided in the crown so that it can be moved in the axial direction. The second floor part has an eyelet 104, by means of which it can be hung on a hook 106 of a jib. The second stick part 26a is guided via a locking sleeve 108 in the crown 8a. For this purpose, the second stick part 26a is equipped with an axial elongated hole 110 through which a bolt 112 engages, which penetrates the locking sleeve 108 and is fastened in the crown 8a.

Das Seil 28a der Seilwinde 22 ist mit dem zweiten Stockteil 26a verbunden. Beim Öffnen des Schirmes wird der Schieber 16a gegen den zweiten Stockteil 26a bewegt, bis der Stockteil in die Öffnung 102 des Schiebers 16a eingreift. Dabei wird der Stockteil 26a in die Arretierhülse 108 eingezogen und die Arretierhülse 108 wird über einen Zapfen 114 des Auslegers gestülpt, der den Haken 106 trägt, an dem der Stockteil 26a angehängt ist. Dadurch ist der Schirm gegen ungewolltes Lösen und Verschwenken an dem Zapfen 114 des Auslegers arretiert.The cable 28a of the cable winch 22 is connected to the second floor part 26a. When the screen is opened, the slide 16a is moved against the second stick part 26a until the stick part engages in the opening 102 of the slide 16a. The stick part 26a is drawn into the locking sleeve 108 and the locking sleeve 108 is placed over a pin 114 of the boom, which carries the hook 106 to which the stick part 26a is attached. As a result, the screen is locked against unintentional loosening and pivoting on the pin 114 of the boom.

Die Figur 7 zeigt eine weitere Seilwinde 22a, die eine Abwandlung der Seilwinde 22 der Figuren 3 und 4 ist, sodass gleiche Teile mit gleiche Bezugszeichen versehen sind. Die in den Lagerplatten 50a,50b des Gehäuses gelagerte Seiltrommel 48a für das Seil 28 weist einen Achsstummel 116 auf, der die Rastvorrichtung 52 mit dem Rastkranz 56, die Bremsvorrichtung 54 mit der Bremsscheibe 64 und über eine Gewindeverbindung die Handkurbel 24a trägt. Hierzu sind der Achsstummel 116 mit einem Aussengewinde 118 und eine Nabe 120 der Handkurbel 24a mit einem Innengewinde 122 versehen. Weiter enthält der Achsstummel 116 die Blockiervorrichtung 81a. Diese wird gebildet durch eine Achsverlängerung 124, auf der der Anschlag 82a in Form einer Mutter angeordnet ist, die über einen Sicherungsring 90 und eine Feder 84 mit einer Stirnseite 126 der Nabe 120 der Handkurbel 24a zusammenwirkt. Die Seilwinde 22a ist ferner mit der Freilaufvorrichtung 71 ausgestattet, welche die Freilauftaste 72 enthält, die mittels Vorspannfeder 78 in FREI Stellung vorgespannt ist und mittels des Haltestiftes 74 mit dem Arretierprofil 74 der Seiltrommel 48a in der bereits oben beschriebenen Weise zusammenwirkt.FIG. 7 shows a further cable winch 22a, which is a modification of the cable winch 22 of FIGS. 3 and 4, so that the same parts are provided with the same reference numerals. The cable drum 48a for the cable 28, which is mounted in the bearing plates 50a, 50b of the housing, has an axle stub 116 which carries the locking device 52 with the locking ring 56, the braking device 54 with the brake disc 64 and, via a threaded connection, the hand crank 24a. For this purpose, the axle stub 116 with an external thread 118 and a hub 120 of the hand crank 24a provided with an internal thread 122. The stub axle 116 further includes the blocking device 81a. This is formed by an axis extension 124, on which the stop 82a is arranged in the form of a nut, which interacts via a locking ring 90 and a spring 84 with an end face 126 of the hub 120 of the hand crank 24a. The cable winch 22a is also equipped with the freewheel device 71, which contains the freewheel button 72, which is pretensioned in the FREE position by means of pretensioning spring 78 and which cooperates with the locking profile 74 of the cable drum 48a by means of the retaining pin 74 in the manner already described above.

Die Seilwinde 22a funktioniert analog der Seilwinde 22 der Figuren 3 und 4, das heisst, beim Öffnen des Schirmes wird die Handkurbel 24a im Uhrzeigersinn gedreht und schraubt sich dabei unter dem Einfluss der entgegenwirkenden Seilkraft über das Aussengewinde 118 auf das Innengewinde 122 des Achsstummels 116 und presst dabei die Nabe 120 der Handkurbel 24a über die Bremsscheibe 64 gegen den Rastkranz 56 der Rastvorrichtung 52 bis die Antriebskraft der Handkurbel grösser ist als die Zugkraft des Seiles, sodass der Rastkranz 56 und die Seiltrommel 48a mitgenommen werden und das Seil 28 aufwickeln. Beim Schliessen des Schirmes wird die Handkurbel 24a im Gegenuhrzeigersinn gedreht, wodurch die Gewindeverbindung unter dem arretierenden Einfluss der Rastvorrichtung 52 zwischen der Handkurbel 24a und der Seiltrommel 48a gelöst wird und die Bremsvorrichtung 54 als Rutschkupplung wirkt und das Seil 28 kontrolliert von der Seiltrommel 48a ablaufen kann. Um den Freilauf des Seiles 28 zu erzielen, muss die Freilauftaste 72 der Freilaufvorrichtung 71 betätigt werden, welche mittels des Haltestiftes 74 am Arretierprofil 76 einwirkt und die Seiltrommel 48a arretiert hält. Daraufhin kann die Handkurbel 24a soweit zurückgedreht werden bis die Stirnseite 126 der Nabe 120 der Handkurbel 24a an dem Anschlag 82a der Blockiervorrichtung 81 a ansteht, wodurch die Bremsvorrichtung 54 und damit die Rastvorrichtung 52 gelöst sind und die Seiltrommel 48a beim Loslassen der Freilauftaste 72 unter Mitnahme der Handkurbel 24a frei drehen und das Seil 28 ungehindert frei ablaufen und sich schliesslich der Schirm ungehindert schliessen kann. Die Blockiervorrichtung 81a wird erst wieder gelöst, wenn die Handkurbel 24a eine im Uhrzeigersinn erfolgende Öffnungsbewegung ausführt und die dabei anwachsende Seilkraft die Blockierung löst und damit die Bremsvorrichtung 54 und die Rastvorrichtung 52 aktiviert.The cable winch 22a functions analogously to the cable winch 22 of FIGS. 3 and 4, that is to say that when the screen is opened, the hand crank 24a is rotated clockwise and, under the influence of the counteracting cable force, screws onto the internal thread 122 of the axle stub 116 and via the external thread 118 The hub 120 of the hand crank 24a presses via the brake disk 64 against the locking ring 56 of the locking device 52 until the driving force of the hand crank is greater than the tensile force of the cable, so that the locking ring 56 and the cable drum 48a are taken along and wind up the cable 28. When the screen is closed, the hand crank 24a is rotated counterclockwise, as a result of which the threaded connection is released under the locking influence of the latching device 52 between the hand crank 24a and the cable drum 48a and the braking device 54 acts as a slip clutch and the cable 28 can run off the cable drum 48a in a controlled manner , In order to achieve the freewheeling of the rope 28, the freewheeling button 72 of the freewheeling device 71 must be actuated, which acts on the locking profile 76 by means of the retaining pin 74 and holds the rope drum 48a locked. The crank handle 24a can then be turned back until the end face 126 of the hub 120 of the crank handle 24a abuts the stop 82a of the blocking device 81a, as a result of which the braking device 54 and thus the latching device 52 are released and the cable drum 48a when the freewheel button 72 is released, taking it with it the crank handle 24a can rotate freely and the rope 28 can run freely and finally the screen can close without hindrance. The blocking device 81a is only released again when the hand crank 24a is in the position Executes clockwise opening movement and the increasing rope force releases the blockage and thus activates the braking device 54 and the locking device 52.
