Description of Invention

Improvements in or relating to a wheeled vehicle.

This invention relates to a wheeled vehicle, and particularly to such a vehicle suitable for use by children.

A wide variety of tricycles, scooters, go-karts etc. are available for use by chi ldren and. in order to meet the desires of children it is often necessary for a single family to purchase separately two or more of these vehicles for a single chi ld. Clearly the child can only use one of these vehicles at a time and thus, at any given time any remaining vehicle is not used. If more , than one vehicle is bought more space is required to store the vehicles, for example during the winter months, and the expense of purchasing more than one vehicle may be prohibitive, considering the relatively short length of time that a child will be able to use a particular size of vehicle.

The present invention seeks to provide a vehicle which may obviate or reduce the problems outlined above.

Accordingly, the invention provides a kit of parts for assembly to form a wheeled vehicle, which kit of parts may be assembed in a plurality of relative positions to form a plurality of relative positions to form a plurality of different vehicles.

The vehicles may advantageously be selected from the group comprising a tricycle, a bicycle, a go-kart and a scooter. Preferably, the kit of parts comprises a front wheel frame assembly that is connectable with a chassis assembly in a plurality of relative orientations the front wheel assembly being adapted to carry at least one wheel, and the chassis assembly being adapted to carry at least one wheel. Desirably the front wheel frame assembly is pivotably connectable with the chassis assembly via connection means comprising a pair of spaced apart plates connected to the front wheel frame

dnd adapted to receive and retain therebetween a mounting member fixed at one end of the chassis assembly.

Conveniently, the mounting member be fixed in one of at least two selectable angular orientations relative to said plates. Desirably, the front wheel frame assembly presents, at its lower end, a pair of forks for receiving a wheel for rotation therebetween and. preferably, the front wheel frame removably receives at its upper end. a handlebar assembly, the handlebar- assembly being of selectively positionable in a plurality of orientations relative to said front wheel frame.

Advantageously, the handlebar assembly is received within the front wheel frame for telescoping movement relative thereto, there being means for retaining the handlebar assembly in at least one selected relative telescopic position.

Preferably, the handlebar assembly has a first linear portion to be received in the front wheel frame, and a second portion inclined thereto, said handlebar assembly being receivable within the front wheel frame assembly in a first position or in a second reversed position.

In a preferred embodiment the chassis is cranked, and the chassis is connectable with the front wheel frame assembly with the chassis in a first position, or with the chassis in a second inverted position.

In order that the invention may be more readi ly understood, and so that further features thereof may be appTeciated. a vehicle embodying the invention wil l now be described, by way of example, with reference to the accompanying drawings, in which:

FIGURE 1 il lustrates schematically the front part of one configuration of a vehicle made from a kit of parts in accordance with the invention;

FIGURE 9 i llustrates a vehicle in accordance with the invention in a modified go-kart configuration; and

FIGURE 10 il lustrates a vehicle in accordance with the invention in a scooter configuration.

Referring to the drawings, and especially to Figures 1 and 2. a vehicle embodying the invention is generally indicated 1. The vehicle 1 comprises a rear chassis assembly 2 connectable with a front frame assembly 3 via chassis engagement means generally indicated at 4. The front frame assembly 3 comprises a pair of spaced apart elongate members 5. At their lower regions the members 5 define front forks 6 for removably receiving a wheel 7. The wheel 7 is mounted for rotation between the forks 5 on an axle member 8 fixed to the forks 5 by retaining nuts 9.

Pedals, not shown may be provided for direct drive of the front wheel. However, the pedals should be easily removable so that they can be discarded and stored when not required.

At least in their upper region, the members 5 are hol low and are adapted to receive, for telescoping movement therein, a handlebar assembly 10. The handlebar assembly is illustrated in Figure 5. The handlebar assembly 10 comprises two parallel spaced apart elongate elements 1 1 that are connected together βs wi ll now be described. Each element 1 1 can be considered to comprise two sections, namely a lower telescoping section 12, that is adapted to be received within the upper region of the sectional elements 5 of the front frame assembly 3, and an upper inclined section 13. The elements 1 1 are located parallel with each other in corresponding orientation. A handle assembly interconnects the free ends of the inclined sections 13 of the elements 1 1 , defining outwardly and upwardly extending handgrip portions 14 and a transverse connector portion 15. The elements 1 1 are also interconnected by a crossbar 15 positioned just below the juncture of the inclined portion 13 and the telescoping portion 12 of each element 1 1. The region bounded by the connector portion 15, the inclined portions 13 and the crossbar 16 may be provided with an infil panel. As wil l become apparent the provision of the portion 13 at an inclination relative ' to the axis to the telescoping section 12 of each handlebar element 1 1 is an important feature of this invention. To allow adjustment- of the height of the handlebar assembly 10 relative to the front frame assembly 3 a plurality of holes 17 are provided in each of the elements 1 1 to cooperate with a single pair of holes 18 in the front frame assembly that receive a retaining pin [not shown) to fix selectively the relative position of the handlebar assembly 10,

Referring again to Figures 1 and 2, the chassis assembly 2 comprises a pair of square cross-section elements 19. In a mid region of the chassis assembly 2 the elements 19 are substantially parallel and are connected by a plate assembly 20. Towards the front " of the chassis assembly 2 the elements 19 extend upwardly (in the orientation i l lustrated] and inwardly to meet at an apex 21 that cooperates with the engagement means 4 removably to connect the chassis assembly 2 with the front frame assembly 3 whilst allowing pivotal movement of the front frame assembly about the point of connection for steerage. The elements 19 extend rearwardly to form rear axle supporting members 22 which extend outwardly from, but in the same horizontal plane (as viewed in the Figures] as the mid region of the chassis. A square cross-sectioned tube 23 that interconnects the free ends of the members 22 and extends outwardly beyond the free ends

of the members 22 receives and retains an axle (not shown) that supports rear wheels 24 which are retained in position by wheel nuts 25.

Pin receiving holes 2B are provided In the parallel portion of the chassis assembly 2 to receive, removably, retaining pins for positioning a seat assembly 27 (shown in Figure 4).

Referring to Figures 1 and 3, the chassis engagement means 4 comprises an upper plate 2B and a lower plate 29 that are fixably connected to, and project rearwardly from the elements 5 of front frame assembly 3. The plates 28. 29 are spaced apart, but lie in parallel planes. As best shown in Figure 3 a single hole is provided substantially centrally in the upper plate 28 and a pair of holes 30. 31 are provided in the lower plate 29. A bolt 32 is passable through the hole in the upper plate 28 to pass either through the front hole 30 in the plate 29, the bolt 32 then being parallel to the axis of the elements 5 or through the hole 31 in the lower plate 29 the bolt 32 then bolts inclined relative to the axis of the elements 5. To facilitate this selective cooperation of the bolt 32, the hole in the plate 28 and the rearward hole '31 in the lower plate are formed slightly larger than the hole 30. For example, if the shaft of the bolt is 10mm in diameter, the hole 30 may be

12mm in diameter and the hole in the plate 28 and the hole 31 may be 1 4mm in diameter.

To facilitate connection of the chassis assembly 2 with the frame assembly 3 the chassis assembly 2 is provided, at its apex 21. with a tubular connector assembly 34 that is adapted to receive the shaft 33 of the bolt 32. By passing the bolt 33 through the upper plate 28. the connector assembly 34 and a selected one of the holes 30. 31 in the plate 29 the chassis assembly can be connected as desired to the front frame assembly 3. The lower end of the bolt 33 wi l l be provided with an appropriate nut. It wi ll be appreciated that the relative positions of the chassis assembly 2 and the front frame assembly 3 can be selected by appropriate selection of either the hole 30 or the hole 31 for receiving the bolt 32.

As will be appreciated, the angled nature of both the handlebar assembly 1 0 and the chassis assembly 2 enable a variety of combinations of the respective parts of the vehicle 1 so that the vehicle can be configured

dither as a scooter, a go-kart or βs a tricycle. The configurations of the parts of the vehicle to form these alternative configurations are shown in Figures 5 to 10.

Figures 6 and 7 show two alternative configurations of the vehicle to form a tricycle. To form the tricycle the chassis assembly is inverted from the configuration shown In Figures 1 and 2 and the inverted chassis is connected with the front frame assembly 3 by passing the bolt 34 either through the rear hole 31, to form the arrangement shown in Figure B. or through the front hole 30 to form the arrangement of Figure 7. In either case the handlebar assembly 10 is reversed from the position shown in Figure 1 to provide the typical more upright handlebar arrangement for a child's tricycle. It wil l be appreciated that pedals can be positioned for direct drive of the front wheel as desired and that the seat member 27 can be fixed to the chassis assembly 2 via pins retained in the holes 26. The handlebar assembly 10 is typically positioned in its lowest possible telescoping position.

To arrange the parts of the vehicle as a go-kart (as shown in Figures 8 and 9], the handlebar assembly 10 is reversed, to the orientation shown in Figure 1. and the chassis assembly 2 is also inverted to the orientation of Figures 1 and 2. Again bolt 34 may be secured either in hole 30 or hole 31 of the plate 29 to select one of the two possible positions of the handlebars as desired. The handlebar assembly 10 may be telescoped to any comfortable position. Again the seat 27 is suitably positioned and retained on the chassis assembly 2.

Finally, to arrange the vehicle parts as a scooter, the chassis assembly is positioned in the same configuration as for the go-kart of Figure 8 .with the bolt 32 positioned in the hole 30 to provide a more upright position of the handlebars. The handlebar assembly 10 is reversed to the same configuration as for the tricycle of Figures 6 and 7 and is telescoped outwardly to the desired height for a scooter. In this configuration the seat 27 is omitted and the plate 20 provides a- foot support.

It will be appreciated that any suitable materials can be used for manufacture of the frame assemblys and for the wheels and that the frame assemblys may be of square, circular or any other convenient cross-section.

Additional elements, Buch as mud-guards, may also be provided.

Whilst the il lustrated embodiment may be assembled as either a tricycle, a go-kart or as a scooter, it wi ll be appreciated that other arrangements, such as a bicycle or a unicycle may be formed as alternative arrangements in other embodiments.
