Definitions

  • the present invention relates to a device for opening and closing umbrellas comprising a flexible canopy fixed centrally to the top of a pole by means of a retaining member from which a first array of spokes for supporting the canopy extends, the spokes being pivotable between a raised position and a collapsed position, a collar slidable axially along the pole and carrying a second array of support spokes articulated to the spokes of the first array.
  • umbrellas of this type are opened and closed by the manual displacement of the slidable collar along the pole. This operation is inconvenient and difficult and involves considerable physical effort, particularly in the case of large umbrellas. Systems with cables and transmission pulleys have also been proposed for these umbrellas but they have similar problems.
  • the object of the present invention is to avoid these problems and to provide a device for opening and closing umbrellas of the type defined which not only reduces the manual effort, but also ensures the necessary stability of the umbrella under all conditions, even when it is windy.
  • an opening and closing device characterised in that it comprises: - a third array of support spokes articulated to intermediate zones of the spokes of the second array and to a fixed collar of the pole, above the slidable collar, - a rod mounted slidably in the upper part of the pole and carrying the retaining member, - manual operating means for sliding the rod relative to the pole between an extended position and a retracted position, the operating means including a crank supported rotatably by the pole and transmission means inside the pole for transforming the rotation of the crank into a translation of the rod, and - catch means for stopping the rod at the ends of its extension and retraction strokes.
  • the transmission means conveniently comprise a pinion supported for rotation by a radial spindle which is rotatable in the pole and is coupled to the crank, and an axial rack fixed to the rod and meshed with the pinion.
  • the catch means include a radial spring pin carried by the pole and snap-engageable in corresponding upper and lower recesses in the rod, the pin being provided with an external grip for manual release.
  • an umbrella is generally indicated 1 and includes a flexible canopy 2 supported on a vertical pole 3 by means of an opening and closing device, generally indicated 4.
  • the device 4 includes essentially a generally circular retaining member 5, normally of metal, to which the central part of the flexible canopy 2 is fixed by means of a cap 6.
  • the retaining member 5 is fixed to the top of a tubular rod 7 which can slide axially, in the manner made clear below, in the upper part 3a of the pole 3 which, as can be seen better in Figures 4 and 5, is hollow.
  • the retaining member 5 has a ring of paired tabs 8 to which an array of spokes or ribs 9 supporting the flexible canopy 2 is articulated.
  • spoke 9 has a telescopic free end defined by an end part 10 which can be retracted into the spoke 9 against the action of an opposing spring 11.
  • the end portions 10 are inserted in corresponding pockets 12 in the flexible canopy 2 so as to tension it correctly.
  • the spokes 9 are adapted to pivot between the raised position shown in Figure 2, which corresponds to the open condition of the umbrella 1 shown in Figure 1, and the collapsed position shown in Figure 3, which corresponds to the closed condition of the umbrella.
  • a second array of spokes 10 is articulated to the array of spokes 9 at a certain distance from the retaining member 5 and at their lower ends are articulated in turn to a collar 13 which is slidable axially along the upper part 3a of the pole 3.
  • the collar 13 is normally of metal and has an inner sliding ring 14 of self-lubricating plastics material in contact with the outer surface of the pole 3.
  • a third array of shorter spokes 15 is articulated to the spokes 10 at a certain distance from the slidable collar 13 and their upper ends are articulated in turn to a collar 16 which is fixed to the top of the pole 3, that is, above the collar 13.
  • the articulations between the spokes 10 and the slidable collar 13 and between the spokes 15 and the fixed collar 16 are similar to the articulations between the spokes 9 and the retaining member 5.
  • the rod 7 is guided slidably in the upper tubular part 3a of the pole 3 by means of a pair of rings, an upper ring 17 and an intermediate ring 18, also of self-lubricating plastics material.
  • the guide ring 18 is conveniently formed in two parts.
  • a diametral shaft 19 passes rotatably through this ring and is supported at its ends by a pair of bushes 20 fixed radially to the pole 3 and positioned by means of a pair of opposing longitudinal slots 25 in the rod 7.
  • a pinion 21 is keyed to the shaft 19 and meshes with a vertical rack 22 which is fixed, for example, by means of screws 23, to the inside of the rod 7.
  • a crank 24 is fixed to one end of the shaft 19 and can be operated manually to rotate the shaft 19 and, by means of the pinion 21 and the rack 22, to move the rod 7 vertically relative to the pole 3.
  • a pin, indicated 26, is mounted for sliding through a radial passage 27 formed in the wall of the pole 3 and through the sliding ring 18 and has a head 28 at its inner end which is adapted to engage one or other of two holes, an upper hole and a lower hole respectively, formed in the rod 7. Only one of these holes is shown, indicated 29, in Figure 4.
  • the rod 26 is urged radially inwardly of the pole 3 by the action of a spring 30 and has a gripping knob 31 at its outer end, whereby it can be retracted radially so as to be released from one or other of the holes 29 against the action of the spring 27.
