Abstract: Self-propelled aquatic toys lide toy sharks are known having a body portion, a middle tail and an outer tail. The middle tail has been driven to oscillate from side to side while outer tail has flapped freely from side to side. Better propulsion and simulation is, however, achieved by driving the outer tail. In this way, operation of the drive at either limit of oscillation initially drives the outer tail to the same sense, i.e. left or right, as the middle tail and thereafter the middle tail and together with the outer tail is moved from that limit position towards the other limit position.

Abstract: A toy is provided which simulates a marine creature. The toy comprises a body portion and a tail portion with a tail fin pivotally mounted thereto; a battery operated motor housed in a water-tight compartment in the body portion to move the tail and the tail fin relative to the body portion to propel the toy through the water; a drive to drive the tail portion comprising a pair of parallel cranks mounted opposite one another on a single spindle and driven through gearing by the motor; and a drive member extending down within the top portion of the tail, the drive member being provided with a pair of slots, each slot receiving a pin connected to one of the cranks. Buoyancy may be achieved using floats located in the body and tail portions.

Abstract: A plurality of toy vehicle track sections, each having at one or both ends of each track section, a protruding plug portion of plastics material and socket, the socket being adapted to receive a similar plug portion on the next track section, and the plug portion fitting into a similar socket on the next track section, the plug portion or socket having a detent, and the socket or plug portion correspondingly having a detent receiving means for locking engagement with the detent.

Abstract: A floating toy comprising a body simulating a human swimmer or diver, and a battery operated motor housed in a water-tight compartment and connected to the leg(s) and/or arms of the body by a linkage the linkage being such as to cause the legs and/or arms of the said body to oscillate to and fro relative to the body in simulation of the kicking movement of the legs of a swimmer, to propel the toy through water, on which the toy is floating.

Abstract: An electrical connection device for a toy vehicle track constructed of a track base to which conductor rails are mounted. The connection device comprises a contact base, two or more contacts resilently mounted in or on the base, each contact being arranged and extending through a hole in the track base to engage electrically with the conductor rail of the track, and bias elements holding each contact in engagement with the track.

Abstract: A toy track for use with electrically operated self-propelled toys such as vehicles or railway trains comprising a plurality of track section, each track section including at least one pair of electrically conductive rails extending substantially the length of the section and provided at least at one end with an electrical junction means adapted to be joined with a corresponding electrical junction means on the adjacent section, said junction means comprising on the one section an insulating member which protrudes from the end of the track section in overlapping relationship with the adjacent track section and on the adjacent track section a recess adapted to receive said projecting portion, said projecting portion mounting and projecting beyond at least one electrically conductive member for coupling a conductive rail of the respective track section with the conductive rail of the adjacent track section.

Abstract: A submersible toy or model comprising a body having a motor arranged to propel it in a forward direction, a watertight buoyancy compartment, and at least one elevator flap which is preset, or capable of being preset, at a downward inclination to the forward direction of movement of the toy, the surface area of the elevator or elevators, the size of the buoyancy compartment, and the power of the motor all being so related that when the model is placed in water with its elevator(s) in the downward position with the motor on, it continually dives and resurfaces.
