Benefits of technology

The invention is about a small vehicle that can be driven by a motor and has a switch to control power transmission. The vehicle can also have a steering linkage to control its direction. Additionally, the vehicle can have removable performance-altering members that can be connected to the vehicle to change its operation. The vehicle can also have a voltage-controlled switch to control the motor. The technical effects of this invention include improved control and performance of small vehicles through the use of magnetically-responsive members and a removable performance-altering system.

Problems solved by technology

Currently available play sets with electrically powered miniature vehicles suffer from several problems.
While the vehicles are typically capable of reaching high speeds, the tracks for such systems can be expensive.
One problem with this is that, in order to obtain strong acceleration and high speeds, one or more relatively expensive batteries may be needed and these batteries can be drained relatively quickly of their charge.
Additionally, play patterns with some prior art vehicles and track systems can be relatively limited, even in situations where the track is reconfigurable.

Embodiment Construction

[0028]Reference is made to FIG. 1, which shows a set 10 including a miniature vehicle 12, a guideway 14, and other associated components which are used for controlling the operation of the vehicle 12, in accordance with an embodiment of the present invention. FIG. 2a shows the vehicle 12 with its body shell 19 on. FIG. 2b shows the vehicle 12 without its body shell 19 to better show the components underneath. Referring to FIG. 2b, the miniature vehicle 12 includes a chassis 20, a plurality of wheels 22 (shown individually as 22a, 22b, 22c and 22d) which are rotatable with respect to the chassis and a motor 30 that drives two of the wheels 22. In the embodiment shown in FIG. 2b, the driven wheels are the rear wheels 22a and 22b. The rear wheels 22a and 22b are fixedly mounted to a rear axle 26. The motor 30 drives the rear axle 26 via a geartrain 27. It will be understood that, in other embodiments, any single wheel 22 or any combination of wheels 22 may be driven by the motor 30.

Abstract

In an aspect, the invention is directed to a set that includes a miniature vehicle that drives one or more wheels with an on-board motor that draws power from an on-board power source. A switch is provided to control the transmission of power from the power source to the motor. A first drive-related magnetically-responsive member is movable between first and second positions to control whether the switch is off or on. A second drive-related magnetically-responsive member is positionable to interact with the first drive-related magnetically responsive member to move the first drive-related magnetically-responsive member to the second position so as to close the switch.

Description

FIELD OF THE INVENTION[0001]The present invention relates to miniature electrically powered vehicles and sets including guideways on which the vehicles travel.BACKGROUND OF THE INVENTION[0002]Currently available play sets with electrically powered miniature vehicles suffer from several problems. Some playsets incorporate a track that has embedded conductive members. The vehicle contains brushes or conductive members that engage conductive members on the track and draws power from a power source through this engagement. While the vehicles are typically capable of reaching high speeds, the tracks for such systems can be expensive. In some playsets, the vehicle has an on-board power source, in the form of a battery. One problem with this is that, in order to obtain strong acceleration and high speeds, one or more relatively expensive batteries may be needed and these batteries can be drained relatively quickly of their charge. Additionally, play patterns with some prior art vehicles an...
