FR2628054A1 - Vehicle to transport one standing person - is driven by engine situated at front of vehicle to give improved stability - Google Patents

Abstract

The vehicle comprises a horizontal chassis (1) which moves on a front, steering wheel (3) and a rear driving wheel (2). The front wheel has handlebars (4) supported by a suspension fork (7). The rear wheel is driven by an engine (5), whose traction is transmitted by means of a belt (14) controlled by the clutch pedal (23). The platform (1) is held on the lower part of the handlebars by a frame (12). A handle (29) on the handlebars activates, by means of a cable (28), a small fixed pulley (25) connected to another pulley (24) operates the brakes. USE - To transport adults around such places as large factory sites and also as a child's toy.

Description

 The invention relates to vehicles of the scooter type for transporting a standing person.

Currently, there are known scooters operated by a pedal, which drives a chain pi
n under the pressure of the foot, which scooters are used as a toy by young children.

 Another scooter is also known which has a motor for driving the wheels.

A disadvantage of this motorized scooter is that the engine is placed on the rear wheel, not giving good stability.

Another drawback has also been revealed in order to obtain rational braking with a vehicle having this configuration.

A third disadvantage exists in that it is not provided for an articulation of its chassis, making its transport by car, for example, difficult.

 The present invention aims to remedy these drawbacks. The invention, as presented in the claims, solves the problems of stability and space during transport, in that it comprises a horizontal frame the rear end of which is carried by a drive wheel and the end front carries a motor and is connected by a frame to a fork placed on the front wheel which supports a handlebar.

 The handlebar support is provided in the lower part with an articulation mores allowing its folding on the fork and the chassis can quickly be detached from the fork by the removal of two quick couplers positioned at the upper end of the frame .

 This vehicle can be fitted with all regulatory accessories. such as lighting means to see xant and be xu from the rear, as well as acoustic means that 1 'commonly found in trade.

 The internal or electric combustion engine controls the rear wheel by the heme -t trick of transmission elements such as pinion, pulley, chain, idler shaft.

 Given the driver's standing position, this vehicle is fitted with a handbrake which actuates a cable, the latter tensioning a belt which blocks, via pulleys, the drive axis.

This brake has the advantage of being very efficient when braking.

 The invention is set out below in more detail with the aid of drawings showing only one embodiment by way of example.

 Figure 1 shows, in elevation, a front view of the vehicle.

 Figure 2 shows, partially, in elevation, the braking and drive means.

 Figure 3 shows, partially, the drive means.

 Figure 4 shows, in elevation, the front part of the vehicle, with handlebars in the folded position.

 Figure 5 shows, partially, the vehicle in top view.

 The figures represent a scooter comprising a horizontal chassis 1 carried by a rear driving wheel 2 and a front steering wheel 3 which carries a handlebar 4 which chassis 1 carries at the front an internal combustion engine 5 located very low, ensuring good stability, which motor 5 actuates the rear wheel 2 by means of transmission elements which are protected by a lateral casing 6.

 In accordance with the present invention, a fork 7 provided with spring dampers 8 is placed in a known manner on the steering wheel 3 and carries the handlebar 4, which handlebar 4 consists of two vertical and parallel elements 10 which respectively have a articulation 9 for positioning said handlebar parallel to the horizontal frame 1.

 The joints 9 are provided with wrists 11 enabling them to be actuated quickly with one hand.

 The front part of the horizontal chassis 1 is fixed to the fork 7 by means of a frame 12 and wing nuts 13, and supports the engine block 5 which drives the rear wheel 2 by means of a belt 14 which connects the pulley 15 taken out of the engine with a large diameter receiving pulley 16, the axis 17 of which also carries a small pinion 18 which drives the rear wheel 3 through a chain 19 via a large pinion 20.

 This scooter is provided with a clutch comprising a movable roller 21 carried by the upper end of a rod 22, the latter oscillates by its lower end fixed to the chassis 1. A pedal 23 located on the right, on the platform form, actuates the roller 21 which tightens the belt 14 allowing the transmission of the movement of the motor on the pulley 16. When the pedal is released, the clutch is released, the rear wheel 2 is no longer driven.

 Given the relatively reduced speed of this vehicle, the brake consists of a pulley 24 coupled to the pulley lh of large diameter, which pulley 24 is connected to the mcxen of a belt 26 6 to another small fixed pulley 25 placid further.

 The small pulley 25 oscillating on the end of a rod 27 fixed by a rotary axis to the chassis 1, is brought forward by a cable 28 under the action of a handle 29 placed on the handlebar which has the effect of tighten the belt 26 thereby immobilizing the twin pulleys 24 and 16 for stopping the scooter.

 The horizontal frame 1 is covered with a sheet forming a platform 30 intended for the location of the driver's feet.

 The upper part of the cylinder is protected by a grid 31 and the lateral casing 6 contains the transmission and brake elements.

 A handle 32 positioned on the handlebar 4 is connected by a cable 33 to the motor to modulate the acceleration.

 A reservoir 34 is positioned by any suitable means on the front of the chassis 1 next to the engine block.

 The present scooter can indifferently have the engine block and the transmission elements positioned on the right or on the left according to the customs of driving.

 This scooter or mobile vehicle is more particularly intended for the movement of a person in places such as factories, warehouses, as well as for children's games.
