Abstract

A mobile toy is described. The mobile toy includes a wheel assembly having a hubcap for removably engaging a wheel of the wheel assembly. The mobile toy may also include a transmitter having a charging pad for charging of a radio-controlled embodiment of the toy. The transmitter comprises an indicator showing certain states of the toy as well as a storage compartment for housing items associated with the toy. Additional embodiments include an assembly for retaining the toy on the charging pad during charging of the toy. A kit for storing the components of the radio-controlled embodiment of the toy is also described.

Claims

1. A transmitter for a radio-controlled toy, comprising:

a housing having a front, a side and a top;

a control circuit located within the housing;

a charging circuit located within the housing;

a switch extending from the front of the housing and user-operable to activate the control circuit and the charging circuit;

a plug associated with the charging circuit and configured to engage a corresponding jack associated with the radio-controlled toy;

an antenna extending from the top of the housing and operably coupled to the control circuit;

a pair of controls housed within raised portions of the front of the housing and user-operable to control movement of the radio-controlled toy via the control circuit;

a three-way LED indicator located on the front of the housing and configured to indicate an operational mode of the transmitter;

a charging pad located on the top of the housing and configured to charge a battery housed within the radio-controlled toy,

a spring configured to support the radio-controlled toy on the charging pad;

a catch operatively connected to the release button and configured to engage a corresponding groove formed on the underside of the radio-controlled toy to releasably retain the radio-controlled toy on the charging pad;

a release button extending from the front of the housing and user-operable to release the radio-controlled toy from the catch;

wherein the charging pad includes;

first and second slots through which the plug passes for engaging the corresponding jack associated with the radio-controlled toy;

a third slot through which the spring passes; and

a fourth slot through which the catch passes; and

a release assembly configured to releasably retain the radio-controlled toy on the charging pad, the release assembly comprising;

the release button, which is disposed through a bore formed in the front of the housing, the release button including a rod extending from the exterior of the housing through the bore and into an annular recess defined by a sleeve structure located within the housing;

a rim extending around at least a portion of the rod in a coaxial relationship;

a coil spring coaxially positioned about a portion of the rod adjacent to the rim and into the annular recess, wherein the spring biases the rod against an inside surface of the housing via a stop associated with the rod; and

a flange having a beveled surface engaging an actuator associated with the button, the actuator comprising a stepped portion having a coiled spring positioned coaxially there about, wherein the spring abuts a fixed surface and biases the actuator against the flange;

wherein the actuator is coupled to the catch via a coupling device that is configured to impart opposing motion, in a lateral direction, between the actuator and the catch upon depression of the release button;

wherein the catch comprises an elongated surface at its distal end for engaging and retaining the radio-controlled toy on the transmitter; and

wherein the catch extends from the housing in a direction substantially perpendicular to the longitudinal axis of the release button.

2. The transmitter of claim 1 wherein the charging pad further comprises a flange and a lip each extending away from the charging pad and configured to align the radio-controlled toy on the charging pad during charging.

3. The transmitter of claim 1 further comprising a cover operatively connected to the housing and configured to enclose the charging pad and the antenna during non-use, wherein:

the housing comprises a step-down portion configured to accommodate movement of the cover from an open position to a closed position; and

a stepped flange extending from the charging pad is configured to engage a lip of the cover to secure the cover in the closed position.

4. The transmitter of claim 3 wherein:

a first protrusion extends from the step-down portion for receiving a first bore formed through a first flange of the cover;

a second protrusion extends from the step-down portion for receiving a second bore formed through a second flange of the cover, wherein the first and second protrusions extend in opposite directions; and

the first and second protrusions cooperate with the first and second bores, respectively, for rotatably connecting the cover to the housing.

5. The transmitter of claim 1 wherein the catch extends substantially perpendicularly from the top of the housing, wherein the release button extends substantially perpendicularly from the front of the housing, and wherein the top and the front of the housing are substantially perpendicular.
