Definitions

  • the invention relates to a free-arm standing umbrella, in particular for sun and rain protection, according to the preamble of claim 1.
  • a free-arm standing umbrella of this type is known from EP 0 741 531 B1 .
  • This umbrella has a functional technology for the simultaneous extension and retraction of the boom while opening or closing the umbrella part.
  • Figure 3 shown provides a first actuator 84 to the guide carriage 72 to which the boom 10 is pivotally connected while the second actuator 26 is coupled to the organ 84 and is guided along the mast 6 via connecting strut 18 and boom 10 to the slide (rosette) 42, which through Raising or lowering via actuating member 26 spans or closes the umbrella part.
  • Guide carriage 72 and slide 42 perform identical routes.
  • Another revelation shows EP 1 250 065 : An umbrella after Figs.
  • the drive 16 consists of a primary drive wheel 44 which on the one hand drives the cable reel 45 for lifting the mast carriage 14 and on the other hand the cable reel 46 for lowering the mast carriage 14.
  • the stroke lengths of the two actuators 25 and 26 are identical.
  • the object of the invention is therefore to propose a free-arm free-standing umbrella of the type mentioned, which is able to overcome the weak points of the prior art that have been identified.
  • the object of the invention is achieved by a free-arm standing umbrella according to claim 1.
  • the umbrella part is connected to a drive unit on the mast via actuating elements, a first actuating element being connected to the mast slide via first deflection rollers in order to move it over a first functional section.
  • a second actuating element is coupled to the first actuating element via an operative connection and connected to the screen slide via second pulleys in order to move the latter over a second functional path.
  • the umbrella according to the invention has a transmission unit for extending the functional path of the umbrella slide.
  • the translation unit is built as a pulley. In this way, a transmission ratio determined by the number of roller pairs acting in the pulley system and thus the ratio between the first and second functional sections can be set up.
  • the translation unit is built as a mechanical gear. In particular, it can be designed as a toothed gear (claim 3) or as a two-stage cable reel (claim 4). In principle, the translation unit can be integrated into the second actuating member at any advantageous point.
  • the second actuating member is guided by the operative connection along the mast, support element and boom to the slide.
  • the second actuating member is guided from a fixing point on the mast via a deflection roller on the mast slide along from the boom to the umbrella slide.
  • the drive unit (claim 7) it is designed as a gear with two cable reels, a first cable reel for lifting the mast carriage and a second cable reel are provided for lowering the mast carriage.
  • the first actuating member comprises a counter-pull rope for lowering the mast slide.
  • a tension spring for stretching the counter-pull rope and for compensating for winding differences.
  • the free-arm standing umbrella comprises a standing mast 1 with a boom 2, which is guided with its mast-side end 2.1 over a height-adjustable mast carriage 4 and by a pivotable support element 3 from the mast 1 to the boom 2 in position holds.
  • the mast slide 4 can be moved up and down via a first functional section 4.1.
  • the boom 2 At its end 2.3 facing away from the mast 1, the boom 2 carries an umbrella part 5, on the crown 5.1 of which the radial main struts 5.2 and support struts 5.3 with the height-adjustable umbrella slide 5.5 carry the canopy 5.8 made of a flexible sheet material.
  • an advantageously self-locking drive unit 6 with a hand crank 6.1 and / or a motor drive is installed in the mast 1.
  • the drive unit 6 can be equipped with a gear unit 6.3 that increases or decreases in speed.
  • a closed rotating toothed belt 6.6 or a pull rope 6.7 is used as the first actuating element 6.5 for the mast slide 4. If the circulating element is not closed, a counter-pull rope 6.9 can be used for the mast slide 4.
  • a second actuating element 7 for example a cable pull, is coupled directly or indirectly to the first operating element 6.5 at an operative connection 6.8.
  • the screen slide is thereby displaceable over a second functional section 5.7.
  • the second actuating member 7 is fixed with its one end 7.1 below the slide 4 on the mast 1 and guided into the boom 2 via a deflection roller 7.2 on the mast slide 4.
  • the second actuating element 7 is equipped with a transmission unit 8, for example with a pulley block 8.1.
  • a pulley pulley 8.2 is attached to the cable 7, over which the pulley rope 8.3 is guided, which on the one hand is attached to the boom end 2.3 at a fixing point 8.4 and on the other hand carries the screen slide 5.5 via the pulley 5.6.
  • the translation unit 8 is equipped in such a way that the first functional section 4.1 and the second functional section 5.7 have different lengths.
  • a second embodiment according to the Fig. 7 and 8th is the second actuator 7 with the translation unit 8 inside the mast on the Operational connection 6.8 coupled to the first actuating element 6.5 and connected via pulleys from the mast 1 via the boom support element 3 and in the boom 2 with the pulley roller 8.2 of the translation unit 8, which has a greater stroke for the umbrella slide 5.5 than for the mast slide 4 causes.
  • Fig. 8 shows a variant in which the transmission unit 8 is designed as a mechanical transmission with a double cable reel with different diameters.
  • the drive cable reel 8.6 is anchored with its axis 8.5 in the boom 2 and is firmly connected to the end 7.3 of the cable 7 remote from the mast.
  • the output cable reel 8.7 has a larger diameter and is fixedly connected to the screen slide cable 8.8. This results in a different stroke distance for the screen slide than that of the mast slide 4.
  • the transmission unit can be designed as a gear with toothing, which enables more specific gradations of the different stroke distances.
