  • the invention relates to a deterring device used to scare birds.
  • Prior art bird deterrents and scarers come in many different forms. Such devices are all in some way designed to keep birds away from areas or locations to which they are by nature attracted and which they tend to choose as preferred perches, feeding sites or roosts .
  • a first category of deterrents used to keep nuisance birds away from designated areas includes static mechanical devices which cover the area to be protected and which may be nets or screens, or "combs" consisting of sets of metal spikes mounted on strips of material of variable length.
  • a second category of deterrents used to keep nuisance birds away from designated areas is that of electrical devices. These usually consist of two flat or round electrical conductors laid side by side lengthways with a small gap between them in such a way that a bird alighting on them touches both conductors at the same time.

  • the deterring device comprises a plurality of the tubular rod-like elements 14 made of flexible elastic material and projecting from a central block 15.
  • the tubular rod-like elements 14 are connected to the central block 15 by their bottom ends 14a. Starting from this end 14a, the tubular rod-like elements 14 extend upwards and bend under their own weight in such a way as to form a substantially arc-shaped curve.

  • the central block 15 is fixed on a base 18 by which the deterring device 1" can be mounted in a permanent position.
  • the base 18 consists of a pole 19 with a pointed end 19a designed to be inserted into the ground.
  • each tubular rodlike element 14 is hollow and in fluid communication, through a conduit 20, with a source of fluid under pressure, schematically represented as a block 21 in the illustration.
  • An interposed valvular element 22, advantageously of the electrically operated type, is fitted between the pressurised fluid source 21 and the tubular rod-like elements 14 and is designed to control the flow of the pressurised fluid into the elements 14.

  • the outlet openings 24 may be equipped with second audible means designed to emit sounds when the fluid under pressure is discharged through the outlet openings 24 themselves.
  • the control unit 11 activates the electric motor 6 which causes the threaded rod 9 to rotate rapidly for a certain length of time.
  • the rotation of the threaded rod 9 makes the annular slider 4 move up or down thanks to the screwing or unscrewing action of its internal threaded portions 4a engaged with the threaded rod 9.
  • the annular slider 4 imparts this substantially impulsive motion on the rod-like elements 5 fixed to it, causing the elements 5 to move in undulating fashion starting from a static state of equilibrium.
  • This motion is comparable to that of a whip which undulates under the action of the initial impulsive force which gradually gets weaker until the whip returns to the state of equilibrium it had before the impulsive was applied. Birds in the vicinity of the deterring device 1 are scared by the sudden irregular movements of the rodlike elements 5 and thus keep away from the area surrounding the device 1.
  • control unit 11 activates the electric motor 6 which causes the discshaped platform 12 to rotate rapidly for a certain length of time, dragging the rod-like elements 5 along with it and thus imparting on the latter, thanks to their length and flexibility, an undulating motion, represented in the illustration by the dashed lines.
  • birds in the vicinity of the deterring device 1' are scared by the sudden irregular movements of the rod-like elements 5.
  • the deterring device 1" is activated when the control unit 23 forces fluid under pressure into the tubular rod-like elements 14. Thanks to the flexibility of the rod-like elements 14 and the limited number of restraints on them, the fluid under pressure makes them move with undulating motion very similar to a whiplash, as described above and represented by the dashed lines in Figure 4.
  • the fluid under pressure is discharged into the atmosphere through the outlet openings 24. The resulting jet of fluid under pressure may even strike the bird, without harming it in any way but creating alarm which scares it away.
  • the flexible rodlike elements 14 have a first tubular portion which is close to the central blodk 15 and connected to the pressurised fluid source 21, and a second portion which is away from t ⁇ j-e central block and not connected to the pressurised fluid source.
  • the undulating motion is therefore transmitted to the second portion by the first tubular portion driven by the pressurised fluid flow.
  • control unit 11, 23 may comprise a timing device designed to activate the actuating means according to a defined time sequence and/or a sensor designed to detect the presence of a bird close to the deterring device 1, 1', 1 " itself, and/or an optical scanning device also designed to detect the presence of birds in the vicinity of the deterring device itself.
  • These presence sensors which are not illustrated, may be of the laser or ultrasound type.
  • timing, presence sensor and optical scanning devices are of customary type and therefore not described in any detail in terms of structural features .
  • control unit 11, 23 may be connected to the optical scanning device or to the presence sensor. When birds are detected within the operating range of the device, a signal is sent to the control unit 11, 23 to start the actuating means 26.
  • each tubular rodlike element has a respective valvular element, each valvular element being separately controlled by the control unit 23, so that the rod-like elements 14 are activated at different times according to predetermined sequences .
  • the device 1" comprises one or more tubular elements 14 placed on plants, that is to say, on tree branches, hedges or vines.
  • the tubular element or elements 14 may be partly fastened to the plant or to its supporting structures by customary fastening means, such as clips, for example, in order to limit and concentrate the undulating motion of the elements 14 in certain areas of the plant.
