DETAILED DESCRIPTION OF DRAWINGS
Referring initially to FIGS. 1 to 10 there is shown a pogo stick, generally designated 5, according to a first embodiment of the present invention. The pogo stick 5 comprises illuminatable or illumination means 10a, 10b provided on either side of a central member 15. The central member 15 comprises a sheath 20 within which is provided a frame 25 comprising a tubular member 30 (not shown), Also provided within the sheath 20 and tubular member 30 is a biasing means 35 (not shown), which will be described hereinafter in greater detail.
The pogo stick 5 also comprises a leg 65. A lower end of the leg 65 comprises a ground engaging foot 70 which may be made of rubber or the like. An upper end of the leg 65 passes through a lower portion of the tubular member 30 and the biasing means 35 (which is in the form of a coiled spring), and is received within a lower end of an upper portion of the tubular member 30 through an annular wall or baffle (not shown). A lower end of the biasing means 35 is attached to the leg 65 via an annular lip member 75 (not shown), while an upper end of the biasing means 35 abuts the annular wall which is provided at or near a lower end of the upper portion of tubular member 30.
Each handle 40a, 40b comprises a fixed end and a free end, the free ends of each handle 40a, 40b in this embodiment substantially facing one another, as can best be seen from FIG. 1. In a non-operational mode (i.e. without a user standing on the platform means 45) the biasing means 35 bias the leg member 65 to a first extended position, as shown in FIGS. 1 to 5, relative to the frame 25.
Each illumination means 10a, 10b comprises at least one vertically extending tubular member 80. In this embodiment the illumination means 10a, 10b comprises a pair of vertically extending tubular members 80a, 80b located on either side of the frame 25 and sheath 20. Each vertically extending member 80a, 80b is in this example, made from a polymeric or plastics material, e.g. polyvinychloride (PVC), or any other suitably robust and/or shatterproof material.
Each illumination means 10a, 10b comprises a plurality of illumination devices, and in this implementation a plurality of light emitting diodes (LEDs) 85. The plurality of LED's comprise a plurality of sets of LEDs 85a, 85b, 85c, the illumination of which is, in use, controlled by control circuitry 90 provided within electronic enclosure 60. The circuitry 90 controls the illumination of the plurality of sets of LEDs 85a, 85b, 85c such that the LEDs are either nonilluminated, illuminated and/or different sets of LEDs are illuminated at different times, as can best be seen from FIGS. 2, 3, 4, and 5. The illumination effect can
also be seen from FIGS. 7, 8, 9, and 10. The LEDs 85 are in this embodiment powered by battery means 95 provided within the electronic enclosure 60.
Further, the pogo stick 5 comprises switch means 100 for switching the illuminatable or illumination means 10a, 10b on and/or off. The switch means 100 comprises in this embodiment, a rocker switch. However, alternative switches may be provided, as will be appreciated, for example, a push-button switch. Alternatively or additionally, the switch means may comprise a vibration switch or movement sensor, which activates when the pogo stick is in use, or is otherwise moved.
The leg 65 may be made of steel, footrests 50a, 50b from aluminum, support member 55 from steel, connection member 75 from steel, biasing means 35 from a suitable metal, and annular lip member 75 from steel. An inner surface of support member 55 may be provided with a bush 36 (not shown), which may be made from PVC. Further, vertically extending tubular members 80a, 80b may be made from PVC, and the sheath 20 may also be made from PVC, suitably coated or painted to have a metallic appearance. The tubular member 30 may be made from a suitable metal, e.g. steel. Further, the electronic enclosure 60 may be made from a suitable metal. Finally, the foot 70 may be made from rubber or the like, e.g. polypropylene.
In use, a user may hingeably deploy the footrests 50a, 50b from a first non-operational configuration as shown in FIG. 1 to a lowered operational configuration shown in FIG. 2. The user may then switch on the illuminatable means by means of switch 95. The user may then stand on the footrests 50a, 50b and use the pogo stick 5 in a conventional manner. Sequencing of illumination of the LEDs 85, and movement of the pogo stick 5, creates novel lighting effects. These effects can be controlled by the user by virtue of the amount by which the user causes the pogo stick to bounce or jump.
Referring now to FIGS. 11 to 17, there is shown a pogo stick, generally designated 105, according to a second embodiment of the present invention. The pogo stick 105 resembles the pogo stick 5 of FIGS. 1 to 10 in many respects, like parts being designated by like numerals, but increased by “100”.
The arrangement of the upper end of the leg 165 extending within the tubular member 130 can best be seen from FIG. 16.
The tubular member 130 extends substantially longitudinally, and is positioned substantially coaxially with a central longitudinal axis of the pogo stick 105, and comprises a structural member. The tubular member 130 comprises a first upper tubular portion 131 and a second or lower tubular portion 132, and first and second portion 131, 132 being joined end to end. An annular baffle 133 is provided within the tubular member 130 between adjacent ends of the first and second tubular portions 131, 132. A lower end of the second tubular portion 132 provide a tubular bush 136 for guiding the leg member 165, and for spacing the tubular member 130 and leg member 165 one from the other.
Also shown in FIG. 17 is a detailed schematic circuit diagram of LEDs 185 controlled by switch 195, and IC 196.
Referring now to FIG. 18, there is shown a third embodiment of a pogo stick 205 according to the present invention. The pogo stick 205 resembles the pogo stick 5 of FIGS. 1 to 10 in many respects, like parts being designated by like numerals, but increased by “200”.
The pogo stick 205 does, however, have a different handle arrangement 240, wherein the ends of the handles 240a, 240b are connected to one another so as to provide a closed shape. Further, frame members 226a, 226b are provided, which extend to a connection member 227, which connects the frame members 226a, 226b to a tubular member 230, and illuminatable means 210a, 210b. 
It will be appreciated that the embodiments of the invention hereinbefore described, are given by way of example only, and are not meant limit the scope thereof in any way.
It will be particularly appreciated that the disclosed embodiments provide novel lighting effects over prior art pogo sticks.
Further, it will be appreciated that the disclosed pogo sticks of the present invention provide advantage over the prior art in providing a single vertically extending central structural member.
