Definitions

  • the present invention relates to an infant's wheeled vehicle.
  • the invention relates to a tricycle (or trike), particularly one which is compactable from an operative configuration in which the infant may use the tricycle in its usual fashion, and a second stowage configuration which is more compact than the operative configuration.
  • International patent publication WO 2004/096629 discloses a tricycle which is able to be folded from an operating position to a more compact stowage configuration.
  • a steering column extends between a front wheel and the handlebars and is received in a collar pivotally mounted to the seat. The steering column is thus pivotally mounted relative to the seat to enable the steering column to lie at least partially under the seat when in the stowage configuration. To shorten the length of the steering column extending out beyond the seat, the steering column is slidably received in the collar.
  • This prior art tricycle has a number of difficulties. Firstly, the sliding arrangement of the steering column adds complexity to the tricycle, and even in the stowage configuration, the handlebars still extend beyond the seat. Secondly, this tricycle uses rather small wheels. Even so, when the front wheel is in the stowage configuration, the wheel is accommodated by a recess provided in the seat, to enable a more compact folding of the steering column against the underside of the seat. This arrangement is feasible with such small wheels. However, such small wheels are impractical where the tricycle is mainly intended for outdoor use, in which case bigger wheels may be more appropriate.
  • a folding wheeled vehicle for use by an infant, the vehicle being foldable from an operative configuration to a stowage configuration and comprising: a body defining a scat for the infant; wheel assemblies including at least a front wheel assembly having a front wheel and one or more rear wheel assemblies each having at least One wheel, the wheel assemblies movable from the operative configuration where the wheels are ground engageable to the stowage configuration, wherein the front wheel assembly further comprises a steering limiter for limiting the steering arc of the vehicle, wherein the steering limiter is rendered ineffective when the front wheel assembly moves from the operative configuration to the stowage configuration, such that the front wheel is moveable to lie in a substantially flat configuration against the body in the stowage configuration.
  • the front wheel assembly preferably further comprises: a fork portion for receiving the front wheel; a rotatable steering column extending upwardly from the fork portion; and a mounting portion receiving the steering column and pivotally mounted to the body.
  • the steering column may be selectively slideable relative to the mounting portion for more compact storage in the stowage configuration.
  • a manually operable release actuator to permit relative sliding between the steering column and the mounting portion.
  • the sliding of the steering column relative to the mounting portion upon release by the manually operable release actuator renders the steering limiter ineffective.
  • the steering limiter is most preferably effected by engagement of mutually engaging portions on the mounting portion and the steering column, with the mutually engaging portions disengaging on sliding of the steering column from relative to the mounting portion upon release by the manually operable release actuator.
  • the mounting portion includes a collar surrounding the steering column and a pivot projection which is pivotally mounted to the body for pivotal movement of the front wheel assembly.
  • the pivot axis is transverse to the longitudinal axis of the front wheel assembly.
  • the steering limiter is preferably effective in the operative configuration to limit turning of the front wheel assembly to 40° to 45° on either side of a central wheel position.
  • the wheeled vehicle may also include a steering lock to selectively lock the steering column in the central wheel position, preventing rotation thereof and consequent turning of the front wheel.
  • the body may also includes an engagement portion to receive a parent bar enabling the wheeled vehicle to be pushed.
  • the front wheel assembly may also include a handle portion for gripping by hand by the infant.
  • the handle portion is removably and replaceably mounted relative to the body.
  • the front wheel assembly preferably lies at least partially underneath the seat.
  • the front wheel is rotatable about its normal turning axis to lie flat against the underside of the seat in the stowage configuration.
  • the front wheel may be permitted to turn through approximately 90° from its central wheel position and in this approximately 90° position, it therefore lies 'flat' against the underside of the seat when in the stowage position. This enables the most compact form in the stowage configuration.
  • the handle portion extends upwardly forward of the body.
  • the handle portion may be removably receivable in the mounting portion.
  • the handle is removably receivable in the front wheel assembly.
  • the handle portion may be completely separable from the remainder of the wheeled vehicle. Alternatively the handle portion may remain tethered once it is removed. For example, an elastomeric cord may run between the removable handle portion and the mounting portion in which it is received.
  • the handle portion may be operably connected to the front wheel assembly to facilitate steering.
  • turning of the handle portion effects the same or a similar degree of turning of the front wheel.
  • the steering limiter limits the degree of turn permitted by the handle portion and/or the front wheel assembly for stability reasons.
  • the degree of turn permitted by the handle portion and the front wheel may be an included angle of up to about 90°, e.g. 40° to 45° each side of centre.
  • the handle portion may be selectively lockable, preventing rotation thereof and consequent turning of the front wheel, depending upon whether the wheeled vehicle is in self- drive mode, or adult-assisted mode.
  • a steering lock may be provided for this purpose.
  • the handle portion may be in the form of an upright portion with an upper transverse bar such that the handle portion is shaped as a T-piece.
