  • Figure 11 is a sectional view of the device of Figure 10. Detailed Description of the Preferred Embodiments
  • the bird deterrent device of Figures 1 to 4 is indicated generally at 10, and comprises a substantially flat elongate plastics base member 12 which is typically about 30 to 40 cm in length.
  • the base member 12 is provided with a plurality of substantially uniformly spaced sideways projecting portions 14 on each side, the projecting portions on one side being longitudinally positioned between the projecting portions on the other side.
  • a respective upstanding integral boss 16 is provided on the base member 12 in the vicinity of each projecting portion 14, each boss being generally circular and located partly in the projecting portion and partly in the main part of the base member to one side of its longitudinal centre line.
  • two thin rod like members 18 (which although not very sharp, effectively serve as spikes, and will therefore be referred to for simplicity in the rest of this description as spikes) are moulded into each boss 16 at diametrically opposite positions in the boss, so that they project substantially perpendicularly upwardly from the base member 12.
  • the respective ends of a group of four spikes 18 are moulded into each pair of adjacent bosses 16, the spikes in each group being distributed across the width of the base member 12.
  • the spikes 18 are typically about 12 to 15 cm long, and made from resilient galvanised metal wire.
  • the spikes 18 After being moulded into the base member 12, the spikes 18 are bent outwardly from the centre line of the base member in a plane at right angles to the centre line, typically so that in a longitudinal group of four adjacent spikes, their upper ends are approximately uniformly laterally spaced with a total lateral spread of between 10 and 20 cm.
  • each device 10 has pairs of apertures 20 formed along the length of the base member 12, each pair being adjacent a respective boss 16 and having its apertures disposed one on each side of the centre line of the base member.
  • each aperture 20 has a concentric groove or well 22 around it, so that when adhesive is injected into and around the apertures, it fills the groove or well to create a "keying" effect.
  • each device is provided with a projecting connecting element 24, while the other end is provided with a complementary recess 26 to receive and hold the connecting element of the adjacent device.
  • the device 10 is provided with break through notches 28 between each pair of adjacent bosses 16. As best seen in Figure 4, the notch 28 has deeper portions 30 interspersed by significantly shorter shallower portions 32, to reduce the possibility of accidental breakage.
  • FIG. 5 to 9 part of a mould tool 40 for use in making the bird deterrent device 10 is shown in section: the arrows in Figures 5 to 9 indicate the directions of movement of the various principal components of the mould tool.
  • the principal components of the mould tool 40 comprise a fixed mould plate 42 containing sprues 44 through which molten plastic is injected, a floating mould plate 46 containing a mould cavity 48 shaped to form the base 12 of the device 10, a loading frame 50 for bringing the spikes 18 into alignment with holes 52 in the floating mould plate 46 leading into the mould cavity 48, a moving mould plate 54 containing holes 56 aligned with the holes 52 in the floating mould plate 46, and an ejector system 58.
  • Figure 5 shows the loading frame 50 in the position where it has just brought the spikes 18 into alignment with the holes 52 in the floating mould plate 46
  • Figure 6 shows the loading frame in the position where it has just achieved location of the right hand ends of the spikes in the mouths of the holes 52, which are slightly flared to facilitate this
  • Figure 7 shows the moving mould plate 54 in the position where it has just achieved location of the other ends of the spikes 18 in the mouths of the holes 56, which are also slightly flared to facilitate this.
  • the mould tool 40 is opened by moving the moving mould plate 54 and the floating mould plate 46 away from the fixed mould plate 42, and the moulded device 10 is ejected from the mould cavity 48 by the ejector system 58 pushing on the ends of the spikes 18.
  • the removed device 10 is finished by the removal of flash and any other excess plastic attached to the base 12 as a result of the moulding process.
  • the bird deterrent device of Figures 10 and 11 is indicated generally at 60, and comprises a plurality of short individual plastics base members 62 each having four bosses 64 into which each of which a respective single spike 66 is moulded in a process basically the same as that used to mould the bird deterrent device 10.
  • Each base member 62 has substantially parallel sides, and the four bosses 64, and therefore the four spikes 66, are spaced apart diagonally across the base member between the parallel sides.
  • the bosses 64 are formed on the underside of the base member 62 rather than on its upper surface, but this is entirely optional.
  • each base member 62 is substantially flat (or planar) when initially moulded, it is sufficiently flexible and resilient to be bendable about an axis parallel to its sides to render its cross section arcuate, preferably a semicircle.
  • the spikes 66 extend substantially perpendicularly to the upper surface of the base member 62, so that they are all parallel when the base member is flat.
  • the spikes 66 fan out to adopt an angular spread similar to the widest spread of the spikes 18 of the device 10.
  • a multiplicity of the devices 60 are secured to a ledge or window sill of a building by means of an elongate extruded metal or plastics auxiliary base member 68.
  • the auxiliary base member 68 is substantially flat, and has apertures 70 substantially analogous to the apertures 20 of the device 10, to enable it to be secured to the ledge or window sill with adhesive as described earlier.
  • Both side edges of the auxiliary base member 68 extend upwardly and then inwardly to create respective inwardly facing hook-shaped sections 72 running the length of the auxiliary base member, while both side edges of each base member 62 have downwardly projecting hook-shaped sections 74 which, when the base member 62 is bent into its semicircular shape, become outwardly facing and effectively clip into the hook-shaped sections 72 of the auxiliary base member 68.
  • Each base member 62 is thus firmly secured to and held in its semicircular shape by the auxiliary base member 68.
  • the base members 62 are spaced apart along the auxiliary base member 68 so that the apertures 70 remain accessible.
  • the base members 62 can be clipped into the auxiliary base member in their final positions by virtue of their flexibility and resilience, or they can be slid in from one end.
  • the spikes 18 or 66 can be made from stainless steel rather than galvanised wire, and their length and spread can be varied from the values given by way of example to suit particular applications, eg unusually narrow ledges or window sills.
  • the moulded in ends of the spikes 18 and 66 can be flattened or provided with grooves, to key them more securely into the plastics base member 12 or 62.
  • the elongate base member 12 can be provided at intervals along its length with sideways projecting fingers, to tend to prevent it from tilting about its longitudinal axis if birds try to pull on the spikes 18.
  • Another modification which can be made is to form the spikes 18 or 66 in pairs by bending a single metal rod or wire into a generally U-shape or V- shape.
  • the ends of one pair of adjacent ends of each pair of spikes 18 or 66 are integrally joined together, and it is the joined-together ends which are moulded into the base member 12 or 62.
  • a mould tool of the kind described in detail in my UK Patent No. 2 148 133 the disclosure of which is incorporated herein by reference, is used.
  • yet another modification which can be made to the bird deterrent devices of the invention is to mould a pair of electrical conductors into the base member, these conductors being connected within the base member to selected pairs of the spikes.
  • the conductors are connected to a relatively low voltage source of the kind used for electric fences around fields containing sheep or cattle, to thus electrifying the selected pairs of spikes and providing a further deterrence effect.
  • the deterrence effect can be further enhanced by using the voltage source to make the spikes vibrate and/or create a humming noise.
