Abstract: A toy boat includes a screw 29 driven by a driving source 26, a screw bracket 30 configured to support the screw 29 and function as a rudder, and a servo mechanism 31 configured to turn the screw bracket 30 towards a horizontal position. The driving source 26 is mounted on the inner side of a boat body 22. The screw 29 is connected to a drive shaft 27 by a universal joint 28 on the outer side of the boat body 22, wherein the drive shaft 27 is driven by the driving source 26. A screw adjustment mechanism 38 configured to adjust the angle and depth of the screw 29 is provided, wherein the adjustment is centered around a connection part 28a connecting the universal joint 28 and the drive shaft 27.

Abstract: A toy watercraft including: a housing defining an interior section of the watercraft; a motor mounted in the housing; a propeller shaft operatively connected to the motor and extending through an opening in the housing; a propeller mounted on an end portion of the propeller shaft; and a propeller shaft sealing arrangement for preventing water from entering the housing through the opening in the housing. The propeller shaft includes a polygon shaped propeller driving element that is countersunk into a rear portion of the propeller. A shaft stabilizing arrangement is positioned adjacent an end of the shaft where the shaft connects with the motor.

Abstract: A turbine assembly with directional control for use in a toy watercraft, including: a turbine housing defining an impeller cavity and including a forward opening and a rearward opening; a directional control valve positioned in the impeller cavity and having a valve opening in a sidewall thereof, the directional control valve being operable to rotate to a first position which closes the forward opening in the turbine housing and aligns the valve opening with the rearward opening in the turbine housing, and a second position which closes the rearward opening in the turbine housing an aligns the valve opening with the forward opening in the turbine housing; and a motor driven impeller positioned in the directional control valve.

Abstract: The present invention relates to a magnetic drive and clutch assembly, especially to an assembly suitable for use in radio or remote-controlled toys and model vehicles. There is described a magnetic drive for a wheel or other rotating body comprising (i) a motor assembly (23) coupled to an axle (30) carrying a housing (14) carrying at least one drive magnet (15) of a chosen polarity, and (ii) a wheel (27) or other rotating body including at least one wheel magnet (9) of the opposite polarity; the motor assembly and wheel (or other rotating body) being mounted for support such that the drive (15) and wheel (9) magnets are positioned adjacently axially with a spacing therebetween.

Abstract: A water propelled toy torpedo including a main housing having an open forward end and an open rearward end. A battery pack is disposed within the main housing inwardly of the open forward end. A battery cap is disposed within the open forward end of the housing in communication with the battery pack. A forward portion has a micro switch extending forwardly therefrom. A motor is disposed within the open rearward end of the main housing. The motor is in communication with the battery cap. The motor has a shaft extending rearwardly therefrom whereby an outer end of the shaft is disposed outwardly with respect to the open rearward end of the main housing. A transparent cap portion couples with the open forward end of the main housing. The cap portion has an open inner end and a closed arcuate outer end. The arcuate outer end has a post extending inwardly from an inner surface thereof. An inner end of the post selectively contacts the micro switch of the battery cap to facilitate activation of the torpedo.

Abstract: An apparatus and method of retrieving a radio-controlled fuel-powered model boat is disclosed. The apparatus includes a pivot arm, with a pinion gear and an idler gear, that is attached to the shaft of a secondary motor. The idler gear in said pivot arm engages a driven gear that turns the model boat's propeller shaft by transferring the secondary motor shaft's rotation through gears to the propeller shaft. The apparatus includes a movement limiting bracket that limits the pivot arm's movement to either engage or disengage the driven gear attached to the model boat's propeller drive shaft.
