A second part is clipped onto the first part and defines the floor 122 and the remaining parts of the sidewalls 128 , front wall 120 and rear wall 124 .
  • the front wall 120 is arcuate with a rearward facing concavity and terminating in a front portion 130 of the roof 126 .
  • the rear wall 124 is also arcuate with a forward facing concavity and terminates in a rear portion 132 of the roof 126 .
  • the floor 122 and the sidewalls 128 are flat.
  • the front portion 130 terminates at a rearward facing edge 134 .
  • the rear portion 132 terminates at a forward facing edge 136 .
  • the edges 134 , 136 define a whistle opening 138 in communication with the chamber 118 .
  • the volume of the whistle chamber 118 is between about 0.7 cm 3 and 1.8 cm 3 , preferably about 1.1 cm 3 .
  • the overall height of the whistle chamber 118 is between about 8 mm and 15 mm, preferably about 10 mm to 11 mm.
  • the overall length of the whistle chamber 118 is between about 15 mm and 25 mm, preferably about 18 mm.
  • a width of the whistle chamber is between about 5 mm and 13 mm, for example, 8 mm.
  • a radius defined by the floor 122 and the front wall 120 is between about 3 mm and 5 mm, preferably about 4 mm.
  • a radius defined by the front wall 120 and the front portion 130 is between about 3 mm and 5 mm, preferably about 4 mm.
  • the front wall 120 is shaped so that a distance between the two radii is between about 1 mm and 3 mm, preferably about 2 mm.
  • a radius defined by the floor 122 and the rear wall 124 is between about 2 mm and 4 mm, preferably about 3 mm.
  • a radius defined by the rear wall 124 and the rear portion 132 is between about 2 mm and 4 mm, preferably about 3 mm.
  • the edge 134 is offset relative to the edge 136 , towards the chamber 118 .
  • the offset is between about 0.2 mm and 0.6 mm, preferably about 0.4 mm.
  • the offset serves to feed air into the chamber 118 as shown in FIG. 16 .
  • a pair of vortices is set up in the chamber 118 .
  • One of the vortices is generated at a rear of the chamber 118 while another vortex is generated at a front of the chamber 118 .
  • the interference of the vortices and the pressure build up within the chamber 118 followed by the subsequent escape of air generates the whistling sound.
  • the sound generated is similar to that of a skyrocket and thus provides a festive atmosphere without the danger of fireworks.
  • the two vortices are formed when an airflow velocity drops to between about 1.5 and 4 m/s.
  • the velocity is higher, for example about 4 m/s and higher there only exists a single vortex in the chamber 118 .
  • a whistling tone of the device drops when the device 100 slows down and the two vortices are generated.
  • the device 100 is capable of generating two distinct tones. This enhances the amusement factor and generates an atmosphere of festivity, as would a conventional skyrocket.
  • the town increases by about a “mediant” or “third”, from major key “A” to major key “C”.
  • the device 100 can be launched to travel upwardly for about three seconds. During about the first 70% of this upward flight, the whistle produces a frequency of about 3200 Hz. During the remainder of the upward flight, the frequency drops to about 3000 Hz. At about an apex of the flight of the device 100 , the frequency increases to between about 3600 Hz to 3500 Hz for about one second. Thus, for about the first two seconds of flight, the frequency generated by the whistle is from 3200 Hz to 3000 Hz and then for one second, the frequency is between 3600 Hz to 3500 Hz. It will be appreciated that this is a unique sound associated with an elastically hand-launched projectile. It follows that a user can create an air of festivity usually associated with fireworks. Recently, fireworks have become controversial because of safety issues and the often dramatic effects they can have on pets.
  • the device 100 provides a means whereby a user can generate a festive atmosphere, particularly when the LED 144 is switched on.
  • the front portion 130 of the roof 126 has an arcuate convex profile.
  • the radius of that profile is between approximately 8 mm and 18 mm, for example, about 13 mm.
  • the rear portion 132 also has an arcuate convex profile.
  • the radius of that profile is between approximately 40 mm and 45 mm, for example, about 42 mm.
  • the rear portion 132 is angled generally with respect to the floor 122 to define an included angle of between approximately 20° and 35°, for example, about 25°.
  • the front portion 130 of the roof 126 has an arcuate external convex profile.
  • the radius of that profile is between approximately 8 mm and 18 mm, for example, about 13 mm.”
  • a profile of the front portion 130 is such that an arc defined by its outer surface will intersect with the forward facing edge 136 , if extended.
  • a printed circuit board, LED driving circuitry, or similar can be interposed between the stem 117 and a battery compartment 142 defined by the battery retainer 104 .
  • the stem 117 serves to secure that circuitry in position relative to the battery compartment 142 and also battery cells in the compartment 142 .
  • the battery cells are connected to an LED 144 that protrudes from a rear of the front portion 14 .
  • a switch 146 allows a user to switch on the LED 144 before launching the device.
  • the LED circuitry can be configured so that the LED 144 can strobe at a selected frequency and in different colours, where the LED is a multicolour LED.
  • the device 100 includes an elongate vane member 148 ( FIG. 21 ) that can be folded to define a pair of vanes 150 .
  • the vane member 148 defines a pair of symmetrically opposed slots 152 to accommodate the flight 20 , as shown in FIG. 19 .
  • the vane member 148 also defines a central slot 154 through which the flight 20 and the stem 18 are received when the vane member 148 is mounted on the stem 18 .
  • a pair of pins 156 extends oppositely and outwardly from the stem 18 , close to the front portion 14 to be against a fold 158 in the vane member 148 .
  • the pins 156 are interposed between a pair of lugs or spigots 160 that also extend from the stem 18 at right angles to the pins 156 .
  • the spigots 160 are received through the central slot 154 .
  • the vane member 148 defines two symmetrically opposite slots 162 , each slot 162 being interposed between a respective slot 152 and the central slot 154 .
  • a pair of opposed locating formations 174 extends from the stem 18 .
  • Each locating formation 174 is shaped to be received through a respective slot 162 .
  • the formations 174 are shaped to engage the vanes 150 to retain the vanes 150 in a suitable orientation with respect to each other when they are folded.
  • Each spigot 160 defines a bulbous end 164 .
  • Each end of the vane member 148 defines an opening 166 .
  • Each bulbous end 164 is received through a respective opening 166 to retain the vanes 150 in a folded-over stored condition.
  • the device 100 can be stored in a suitable receptacle, such as a transparent receptacle 172 as shown in FIG. 18 .
  • the device 100 can be protected from damage and can also be presented in an aesthetically pleasing manner.
  • the vane member 148 is comprised of a central portion 168 interposed between a pair of end portions 170 . Each end portion 170 is angularly offset, in opposite directions, relative to the central portion 168 .
  • An angle of offset can be between approximately 3° and 7°, for example, 5°.
  • a user can store the device 100 in the receptacle 172 by first folding the vanes 150 so that the spigots 160 are received through the openings 166 and the locating formations 174 are received through the slots 162 . It will be appreciated that it is not strictly necessary for the user to have the spigots 160 extending through the slots 162 .
  • Simply folding the vanes 150 and inserting the device 100 into the receptacle 172 facilitates retention of the appropriate shape of the vanes 150 when the device 100 is withdrawn from the receptacle 172 . This is enhanced by the offset described above, that serves to ensure that the vanes 150 are folded to facilitate a return to an appropriate position when the device 100 is withdrawn from the receptacle.
  • the locating formations 174 also serve to ensure that the vanes 150 are maintained in their optimal for orientation since the vanes 150 are not released from the formations 174 while the device 100 is being used.
  • the vane member 148 can be of a number of different materials.
  • the vane member 148 can be of a plastics or other suitable material that carries a reflective coating.
  • the device 100 can be particularly noticeable.
  • the LED can shine onto the reflective coating creating an effect similar to fireworks. This coupled with the whistling sounds described above can impart a festive atmosphere and can enhance the enjoyment of the device 100 .
  • the vane member 148 can also be coated so as to generate holographic images.
  • any elements can be integrated, segregated, and/or duplicated
  • any activity can be repeated, any activity can be performed by multiple entities, and/or any activity can be performed in multiple jurisdictions;
  • any activity or element can be specifically excluded, the sequence of activities can vary, and/or the interrelationship of elements can vary.
