Abstract

A battery receptacle in which either of individual dry batteries and individual or packaged nickel-cadmium batteries can be received to be used as a power source for a radio controllable motor toy so that interchangeability of batteries used in the motor toys and space saving can be realized.

Claims

1. In a battery receptacle for radio controllable motor toys including a battery-receiving chamber which is formed in predetermined configuration on a bottom face of a plastic vehicle body of the radio controllable motor toy, batteries in said battery-receiving chamber being used as a power source for a radio receiver and a drive motor of the radio controllable motor toy;

the improvement wherein

said battery-receiving chamber is formed so as to have enough space to receive either of a packaged nickel-cadmium battery unit capable of developing a given combined output voltage and a battery casing capable of receiving a given number of individual batteries;

a cut out portion which is formed on one side wall of the battery receptacle including said battery-receiving chamber so as to receive two connectors and lead wires through which the radio receiver and the drive motor of the radio controllable motor toy are connected to said packaged nickel-cadmium battery unit or the battery casing to be used as the power source therefor; and

two pairs of grooves formed on inner faces of a pair of opposite side walls of the battery receptacle to receive two pairs of projections formed on outer faces of a pair of opposite side walls of the battery casing, one of said opposite side walls of the battery receptacle having also said cut out portion.

2. A battery receptacle as claimed in claim 1, wherein said grooves are vertical.

3. A battery receptacle as claimed in claim 2, wherein said grooves in said one of said opposite side walls are disposed on opposite sides of said cut out portion.
