  • the lever 537 shares a common pivot 538 with the brake shoe 535.
  • a release spring may also be provided as described above in connection with Figure 8(d) .
  • Figure 10(b) shows a plan view of the wheel mounting assembly having brakes from which it will be noted that the lever 537 operates two shoes 535, each acting on a respective one of the pair of wheels 12 sharing a common axle 122.
  • Figure 10(c) shows a front view of the wheel mounting system with the braking arrangement described above.
  • Figures 11(a) , (b) shows a second embodiment of a brake including a centre pull brake with pull-off springs in which.
  • Figure 11(a) is a front view of a wheel assembly having a brake and
  • Figure 11(b) is a section along arrow headed lines B-B of Figure 11(a) .
  • a wheel assembly 561 of different form to that shown in Figures 5(a), 5(b) has a curved member 551 extending forwardly of the wheel axle upwardly toward the lower surface of the platform 1.
  • the member 551 has a socket engaging the outer of the brake control cable 525, while the inner wire 532 passes through the member 551 to couple to a centre pull saddle member
  • the saddle member in turn connects to the brake shoes 535 and the shoes are connected together on a common axle
  • Brake pull-off springs 550 may be helical torsion springs located with one end in a hole in the shoe, and the other end in a hole 555 in the wheel assembly 561.
  • Figure 12(a) , (b) show another wheel mounting arrangement in which the pulley 15 has a centre fixing hole 545, through which a bolt or screw 546 may be inserted to attach the pulley to the underside of the platform.
  • a ball or roller bearing could be provided for rotation of the pulley with respect to the platform, but it has been found possible to dispense with such a bearing, and instead a low-friction washer 560, for example of PTFE, between the bearing faces of the platform and pulley, with the screw 546 left sufficiently loose for rotation of the pulley 15.
  • Diametrically opposite the hole 547 is an oblique socket 544 for engaging with a spigot protruding obliquely from the wheel assembly.
  • Such an arrangement for mounting the driven wheels provides an easy and rapid connection for mounting or demounting the motor connected thereto.
  • On the outer edge of the pulley 15 are two circumferential grooves 542, 543 for the steering cables 25, 28, one groove 543 being deeper than the other groove 542, thus giving a smaller operating radius for the cable associated therewith.
  • Such grooves of differential radial extend give a user the possibility of further changing the steering ratio between the front and rear wheels to cope with different conditions of use as well as the above described use of different cable fixings 21, 22, 23.
  • Figure 13 is a side view of the platform 1 with the engine 503, transmission unit 509 and the centre rear wheels 502 mounted on the platform.
  • the centre rear wheels 502, driven by the motor, are preferably not in contact with the ground unless loaded by a user occupying the platform. This may be achieved by using smaller wheels, a different sized wheel assembly or pulley, or by varying the thickness of the spacer between the pulley and wheel assembly.
  • Such a provision has the advantage that the engine can be run without the platform moving, and provides a safety feature that even with the engine running at speed, no drive will take place if the user is dislodged from the platform.
  • the shape of the toy may be modified as desired and, although the toy has been described with three or more wheels (or pairs of wheels) , the toy is not intended to be limited thereto.
  • the construction of the platform can be of any suitable material such as wood, reinforced plastics, or unreinforced plastics and glass resin fibre. It is also possible to use metal, either in the form of an in-filled platform, or as a space framework, which may be covered with another material, or left open.

Abstract

L'invention concerne un jouet possédant une plateforme (1) sur laquelle se trouve un siège (4) et un repose-pied (5). La plateforme est montée sur des roues (11, 12) pouvant être des roues de planche à roulettes. Les roues sont orientables grâce à un bras (8) qui est relié pour les faire tourner par l'intermédiaire de, par exemple, des câbles (25, 28) de telle sorte qu'elles sont orientables simultanément, les roues avant en sens opposé aux roues arrières. Selon les modes de réalisation du jouet, celui-ci peut être équipé de freins et entraîné par un moteur (503).
