ES2232926T3 - MOTORIZED SYSTEM THAT PROMOTES A TOY THAT IS DIRECTED BY ITS TILT. - Google Patents

Abstract

A motorized propulsion system, designed to be steered by rocking on straight and oblique wheels, comprises a chassis (2), a support and control bar with handles and an accelerator, a motor (1) and driven wheels (5). The motor is located at one end of the chassis, leaving a place between it and a center wheel for one of the user's feet. A place for the other foot is located on the other side of the center wheel. The system also has a speed changer and a pulley to transmit power to the driven wheels.

Description

Motorized system that propels a toy that He steers for his swing.

The present invention aims at of new industrial product, a motorized system, which allows propel a downhill toy that has a chassis, five wheels, a support ramp and is directed by its tilting on wheels straight and oblique lines (French Patent No. 92 12 562).

First this motorized system allows this Descent toy be used on the plane, to avoid Always nasty climbs.

Slopes sufficiently pronounced no they are frequently numerous or close, unlike the land planes that agree because of this motorized adaptation are numerous since this new mechanical toy can be used, by For example, in the handball fields, the running tracks, the go-karting tracks, parking lots and of course, on tracks specially conditioned, covered with asphalt or sand.

The motorized system, as claimed in claim 1, brings a very important change and improvement To the descent toy.

In addition to the fact that it can be used on the flat, its weight and its gauge give it exceptional stability.

The toy without a motor should be of construction Slight because of the climbs.

Accelerations and decelerations, a speed larger especially in curves produce feelings of another dimension.

The toy propelled by the motorized system object of the invention is normally used by only one person, but it is possible for a child to be installed in the part front for you to enjoy more, whenever you roll at a speed moderate

The technique, use, weight and gauge of the Motorized skateboard, are not comparable.

The accompanying drawings illustrate the invention.

Figure 1 shows the toy in general, where the motorized system is fixed, in position to go straight ahead. Figure 2 shows the motorized system in position in a curve.

The motorized system, object of the invention, which propels the wheeled toy that is driven by its Tilt must be adequate and specific. The same happens with Your location

The motorized system (1) is placed on a chassis end (2) on the outer side of the site (11) of the user's foot.

The imbalance caused by this location of the motorized system is restored by one or some counterweights (3) fixed at the other end.

In short circuits, the tilt is almost permanent. No counterweight or counterweight and a motorized system without concordance, it would be difficult to swing the toy and it He would lose all his playful interest.

The simplest and most adapted location of the Motorized system is the rear end of the chassis, but with some inconveniences, it could get in the front and the steering wheels would be placed in this case in the part later.

A braking system on the central wheel and a second on the driving wheels, complete the safety of this new set.

Its two handles (4) are placed on the ramp support.

The gauge and the weight of the new motorized toy they are different from those of the descent toy and two of the four peripheral wheels become motive.

Thus, the size of the wheels, the wheel size difference as well as the over lift of the peripheral wheels in relation to the central wheel may be different.

The steering wheels can also be set more oblique.

To obtain a necessary stability at performance of this sports toy, the length of the chassis is of approximately 1.80 m, the width of approximately 0.80 m and The weight of the toy set of about 120kg.

The driving wheels (5) must be robust and the central wheel (6) that serves as a pivot, can exceed 0.60 m of diameter.

All this allows to easily roll over 60 km / hour

The gauge and the weight of the set may vary according to the desired use and speed.

When the chassis is tilted, it activates the system motorized, comprising a set of axle (7) and wheels (5) engines equipped with very round tires, in one piece, that allows to propel the toy or with the two driving wheels at the same time to go straight, or only with one of them to turn The wheel that does not touch the ground rotates in a vacuum.

The recreational and sporting requirements of this toy need a lot of accelerations and decelerations fast.

Mobilize a hand, at the moment it speeds change, it is a particular disadvantage in curves

The choice of a sufficiently powerful engine to avoid having to use the speeds has the disadvantage to increase the weight of the whole, as well as the consumption.

The system of some velomotors whose speeds are changed with the throttle using a cable It has practically been abandoned.

The best adapted solution that allows benefit from parts manufactured in large series, is the use of variable speed drive

The scooter that was designed to circulate mainly in the city it comprises a motor set and two variable speed drives in the same compact block that corresponds to the requirements required for the propulsion of this toy, as for this part.

The driving wheel is replaced with a pulley (9), this pulley is placed near the pulley (10) that drives the shaft (7) that spins the wheels.

The pulley (9) is placed on the inner side of the speed variation system (8).

In this way, the two pulleys are placed in the center of the axle (7) that drives the driving wheels.

This allows to prevent the shaft from being driven by the pulley by one of its ends, which would be disastrous mechanically, especially when the driving wheel is in the Another extreme was the only one to propel the toy.

The pulleys are connected by a belt. The pulleys can be replaced with pinions and the belt with a chain.

Another way to do it allows not having to use pulleys, but you need a special adaptation of the end outside of the gearbox or variation system of speeds, as well as an adequate position of the motorized system. It consists in that the axle that drives the driving wheels crosses directly the outer end of the demultiplication system or of variation of speeds and is driven by grooves, by example, in the center of its length.

The motorized system placed more or less by on the axle that drives the driving wheels, it has its system of outward multiplication and should leave enough space (11) for the user's foot that is placed between said motorized system (1) and the central wheel (6).

The centrifugal clutch allows to control the propulsion only with the throttle (12).

Accelerations and decelerations are very numerous The hand that drives the throttle also serves, in association with the other hand, to push and pull the ramp to Lead the toy.

To have enough power to press the wheels, legs and arms of the user should to be separated.

It is a position that is about that of windsurfing users.

To combine the two positions of one of the two hands, the throttle (12) is placed on the ramp (13) of support, vertically or almost vertically with one of the two places (11) where the user places the feet.

The use of very rounded tires is indispensable; allows smooth tilt and get the sufficient adhesion when the wheel is only in cornering contact with the ground on its outer side.

This new motorized toy, very sporty may be acquired by leisure centers, clubs, collectivities as well as by individuals.

Claims (3)

1. Motorized system (1) that propels a toy that is driven by its tilting on fixed and oblique wheels (5, 6), characterized in that the motorized system (1) is placed at one end of the chassis (2) so that leaves a location (11) sufficient for the user to place the foot between said motorized system (1) and a central wheel (6), because the imbalance caused by this location of the motorized system is restored by a counterweight (3) or several fixed at the other end, because the motorized system comprises an axle (7) and drive wheels (5), equipped with very rounded tires, in one piece, and because the accelerator (12) is placed on the ramp (13) of support, vertically or almost vertically with one of the two places (11) in which the user places the feet, which allows this set, by its tilting, to propel the toy either with the two driving wheels at the same time, or Only with one of them. 2.
